PROSPECTUS
                        PROSPECT MEDICAL HOLDINGS, INC.
 
                        3,000,000 SHARES OF COMMON STOCK
            AND 3,000,000 REDEEMABLE COMMON STOCK PURCHASE WARRANTS
 
    This Prospectus relates to the offering (the "Offering") of 3,000,000 shares
(the "Shares") of common stock, $.01 par value per share (the "Common Stock"),
and 3,000,000 Redeemable Common Stock Purchase Warrants (the "Warrants") of
Prospect Medical Holdings, Inc., a Delaware corporation (the "Company"). The
Shares and Warrants are sometimes hereinafter collectively referred to as the
"Securities." The Shares and the Warrants may be purchased separately and will
be transferable separately immediately following completion of this Offering.
 
    Each Warrant entitles the registered holder thereof to purchase one share of
Common Stock at an initial exercise price of $8.40 per share at any time during
the period commencing            , 1999 [the first anniversary of the effective
date of the registration statement filed with respect to the Securities] and
terminating on       , 2003 [the day immediately preceding the fifth anniversary
of said effective date]. The Warrant exercise price is subject to adjustment
under certain circumstances. Commencing            , 1999 [the first anniversary
of said effective date], the Company may redeem the Warrants, in whole but not
in part, at $.10 per Warrant on thirty (30) days' prior written notice to the
Warrant holders, provided that the average closing sales price of the Common
Stock as reported on the American Stock Exchange (the "American Stock Exchange")
equals or exceeds $18.00 per share for any twenty (20) trading days within a
period of thirty (30) consecutive trading days ending on the fifth trading day
prior to the date of the notice of redemption. See "Description of Capital
Stock."
 
    Prior to this Offering, there has been no active trading market for the
Common Stock or the Warrants, and there can be no assurance that such a market
will develop after the completion of this Offering or, if such a market does
develop, that it will be sustained. It is currently anticipated that the initial
public offering prices of the Common Stock and the Warrants will be $6.00 per
share and $.10 per Warrant, respectively. For information regarding the factors
considered in determining the initial public offering prices of the Securities
and the terms of the Warrants, see "Risk Factors" and "Underwriting." The
Company intends to apply to list the Shares and the Warrants on the American
Stock Exchange under the symbols "PXX" and "PXX.W," respectively. No assurance
can be given that such application will be granted or, if granted, that an
active trading market will develop.
THE SECURITIES OFFERED HEREBY INVOLVE A HIGH DEGREE OF RISK AND IMMEDIATE
       AND SUBSTANTIAL DILUTION. SEE "RISK FACTORS" BEGINNING ON
                             PAGE 8 AND "DILUTION."
  THESE SECURITIES HAVE NOT BEEN APPROVED OR DISAPPROVED BY THE SECURITIES AND
 EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION NOR HAS THE SECURITIES
  AND EXCHANGE COMMISSION OR ANY STATE SECURITIES COMMISSION PASSED UPON THE
      ACCURACY OR ADEQUACY OF THIS PROSPECTUS. ANY REPRESENTATION TO THE
                        CONTRARY IS A CRIMINAL OFFENSE.

                                  THE COMPANY
 
    The Company primarily manages physician organizations that specialize in
providing medical services to individuals enrolled in managed care programs
offered by health maintenance organizations ("HMOs"). The Company's affiliated
physician organizations have entered into agreements with HMOs. Under these
agreements, the affiliated physician organizations provide medical services to
the HMO's enrollees in consideration for its payment of prepaid monthly fees
known as "capitation" payments. Physician organizations include medical groups
that employ physicians and independent practice associations that contract with
physicians.
 
    Physician organizations increasingly are viewing managed care
administrators, such as the Company, as a means to increase their bargaining
power in response to the growth of HMOs. Additionally, physician organizations
are responding to the cost-containment pressures within the managed care
industry by affiliating with managed care administrators, such as the Company,
to control economic risk and perform the non-medical management and
administrative tasks that arise from the practice of medicine in a managed care
setting.
 
    The Company's growth strategy has thus far focused on the acquisition by its
affiliated physician organizations of other medical groups and independent
practice associations. These organizations provide services in Orange, Los
Angeles, Ventura and Santa Barbara Counties of the State of California. As of
June 30, 1998, the Company had approximately 350 primary care physicians and
approximately 1,390 specialists within its provider network. More specifically,
the Company has grown principally through four strategic acquisitions (Santa
Ana/Tustin Physicians Group, Sierra Medical Group, Western Medical Group and
Antelope Valley Medical Group (as such terms are defined herein)) and through
internal growth by the addition of new enrollees to its existing affiliated
physician organizations. As of June 30, 1998, the affiliated physician
organizations provided services pursuant to agreements with 17 HMOs. The table
set forth below shows the increase since July 31, 1996, when current management
assumed control of the Company, in the number of commercial, Medicare and
Medicaid enrollees served by the Company's affiliated physician organizations.

share of the potential acquisition candidate's own local marketplace; (iii) a
favorable hospital relationship; and/or (iv) willingness of the acquisition
candidate's management to continue managing the acquired entity following its
acquisition.
 
    Currently, the non-physician components of hospitalization and hospital
facilities are generally provided to the enrollees by hospitals that contract
with and are paid by the HMOs. The future strategy of the Company is to provide
and manage all health care services, including hospital health care services. To
implement this strategy, the Company intends to obtain a license pursuant to
California law which will allow the Company to contract with HMOs on a full-risk
basis. The Company also intends to seek a certification under federal law which
will allow the Company to contract with the United States Department of Health
and Human Services, Health Care Financing Administration ("HCFA"), to manage and
provide health care services on a full-risk basis directly to Medicare
beneficiaries without an HMO intermediary.
 
    Southern California is a highly-developed managed care market. Management
believes that there is more economic opportunity in developed markets because
(i) physicians and hospitals in developed markets have established practice and
referral patterns that are consistent with providing services within a managed
care framework and (ii) there is generally a higher concentration of physicians
and hospitals in a developed market, creating a more competitive environment
with greater opportunities for the Company and its affiliated physician
organizations to negotiate more favorable provider contracts. The Company
believes that the managed care industry operates most effectively on a regional
basis, and is affected most by provider competition, physician referral
patterns, custom and practice and local hospital relationships. Management also
believes that developing a significant local market presence permits economies
of scale and greater efficiencies through centralization of operations.
 
    The Company believes that physician management fosters better relationships
with providers. The Chief Executive Officer, Jacob Y. Terner, M.D., and
President, Gregg DeNicola, M.D., have been practicing physicians. More recently
Dr. Terner served as Chairman of the Board and Chief Executive Officer of
Century MediCorp, Inc. ("Century MediCorp"), a publicly-traded corporation
operating through three wholly-owned HMO subsidiaries, hospitals and an
affiliated independent practice association, until its October 1992 merger with
a major publicly-traded HMO. The Company typically retains senior management of
the entities that it acquires.

    The Company provides management and other administrative services to
physician organizations that specialize in managed care, including personnel,
claims administration, utilization management and quality assurance, case
management and data collection and management information systems. The Company
also helps these physician organizations by negotiating capitation rates and
incentive payment arrangements with HMOs. The Company assists physician
organizations that accept full financial risk for all physician services to be
provided under an HMO agreement. The Company and its direct subsidiaries are
prohibited by California law from engaging in the corporate practice of medicine
and, therefore, do not practice medicine or employ physicians. The physician
organizations affiliated with the Company hire and contract with physicians and
ancillary health care service providers for the provision of medical services.
 
    The Company has entered into a long-term management services agreement with
each affiliated physician organization. The Company helps its affiliated
physician organizations acquire other physician organizations that have
contracts with HMOs. The Company then enters into a long-term management
services agreement with each newly-acquired physician organization. Under the
long-term management services agreements, the Company provides the physician
organizations with certain management and administrative support services as
described above in return for a fee calculated with reference to certain
components of the physician organization's revenues and the Company's costs of
providing its services. The Company's management fee fluctuates based on the
profitability of the affiliated physician organizations as the Company is
entitled to a residual interest in the profits of the affiliated physician
organizations. The Company's fee arrangements are structured so that, by
enabling its affiliated physician organizations to deliver required medical
services in a more cost-effective manner, the Company will benefit from the
savings so obtained.

GENERALLY. PROSPECTIVE INVESTORS ARE CAUTIONED THAT ANY SUCH FORWARD-LOOKING
STATEMENTS ARE NOT GUARANTEES OF FUTURE PERFORMANCE AND INVOLVE RISKS AND
UNCERTAINTIES. ACTUAL EVENTS OR RESULTS MAY DIFFER MATERIALLY FROM THOSE
DISCUSSED IN THE FORWARD-LOOKING STATEMENTS AS A RESULT OF VARIOUS FACTORS,
INCLUDING, WITHOUT LIMITATION, THE RISK FACTORS SET FORTH BELOW AND THE MATTERS
SET FORTH IN THIS PROSPECTUS GENERALLY.
 
    LACK OF PROFITABLE HISTORY AND NEGATIVE WORKING CAPITAL.  The Company has a
limited history of operations and earnings following implementation of the
Company's current growth strategy in mid-1996. The Company's audited financial
statements for the fiscal years ended September 30, 1995, 1996 and 1997 reflect
net income (loss) of $188,250, $555,428, and $(2,639,415), respectively, and the
Company's unaudited financial statements for the nine months ended June 30, 1998
reflect net income of $375,516. There can be no assurance that the Company will
be able to integrate and manage profitably the physician organizations with
which it affiliates, or that the Company will be able to successfully and
profitably manage HMO and other payor contracts on behalf of these physician
organizations. See "Selected Consolidated Financial Data" and "Management's
Discussion and Analysis of Financial Condition and Results of Operations." In
addition, the Company had negative working capital of $2,569,000 and $2,003,000
at June 30, 1998 and September 30, 1997, respectively.
 
    DIFFICULTY IN CONTROLLING HEALTH CARE COSTS; CAPITATED NATURE OF
REVENUE.  As of June 30, 1998, the Company received approximately 89% of its
revenues from agreements with HMOs. The Company's continuing profitability
primarily depends upon the ability to pay out less in medical and administrative
costs than the capitation revenue received from HMOs. HMOs are increasingly
overseeing the provision of and the prices charged for medical services with the
goal of reducing costs and lowering capitation payments. The Company's success
therefore depends in large part on the effective management of health care
costs, including controlling utilization of specialty care and other ancillary
care and purchasing services at competitive prices. Any adjustment downward in
capitation payments caused by the increasing efforts by HMOs to reduce costs
could have a material adverse effect on the Company's operating results and
financial position. In addition, employer groups are becoming increasingly
successful in negotiating reductions in the growth of premiums paid for their
employees' health insurance, which tends to depress the payments for health care
services. At the same time, employer groups are demanding higher accountability
from payors and providers of health care services with respect to measurable
accessibility, quality and service. If these trends continue, the cost of
providing physician services could increase while the level of payment could
grow at a lower rate or could decrease. There can be no assurance that these
pricing pressures will not have a material adverse effect on the operating
results and financial condition of the Company.
 
    Agreements with HMOs may also contain shared-risk arrangements under which
additional compensation can be earned based on the provision of high quality,
cost-effective health care to enrollees but which may require that a portion of
any loss in connection with such shared-risk arrangements, including losses
resulting from the provision of hospital services, be assumed by the Company,
thereby reducing the Company's net income. The amount of non-capitated and
hospital costs in any period could be affected by factors beyond the control of
the Company, such as changes in treatment protocols, new technologies and
inflation. To the extent that such non-capitated and hospital costs are higher
than anticipated, revenue paid to the Company may not be sufficient to cover the
costs the Company is responsible for paying. Any such insufficiency could have a
material adverse effect on the operating results and financial condition of the
Company.
 
                                       8

    RISKS ASSOCIATED WITH GROWTH STRATEGY.  The Company's strategy primarily
involves growth through acquisition of additional physician organizations that
specialize in managed care and the expansion of their medical practices;
establishing a health plan with a limited license to provide hospital, ancillary
health care and physician services to commercial and Medicare enrollees within
the Company's service network; and formation and development of a Medicare
Health Plan to provide hospital, ancillary health care and physician services to
Medicare enrollees not currently served by the Company's provider network.
Several of the acquisitions by the Company were large transactions which involve
significant risks and uncertainties for the Company. The Company anticipates
continuing to pursue growth through acquisitions and expansion of existing
medical practices. The success of past and future acquisitions is largely
dependent on the ability of the Company to integrate the operations of the
acquired physician organizations into the Company's operations in an efficient
and effective manner. The histories, business models and cultures of acquired
physician organizations may differ from those of the Company and its affiliated
physician organizations. The process of integrating management services, which
includes management information systems, claims administration and billing
services, utilization management of medical services, care coordination and case
management, quality and cost monitoring and physician recruitment, as well as
administrative functions, facilities and other aspects of operations, while
managing a larger entity with differing histories, business models and cultures,
presents a significant challenge to the Company's management. In addition,
integration must be carried out so that the Company is able to control medical
and administrative costs. The ability to control such costs is key to the
successful future operations of the Company. There can be no assurance that the
Company's acquisitions will be successfully integrated on a timely basis, if at
all, or that the anticipated benefits of these acquisitions, including cost
savings, will be realized. Furthermore, there can be no assurance that any cost
savings which are realized will not be offset by increases in other expenses or
operating losses. The Company will encounter similar uncertainties and risks
with respect to any future acquisitions it may make. Failure to effectively
accomplish the integration of acquired companies could have a material adverse
effect on the Company's results of operations and financial condition. Further,
there can be no assurance that the Company will be able to successfully expand
and manage the physician organizations with which it affiliates. The Company's
growth is dependent on its ability to affiliate with physician organizations, to
manage and control costs, and to realize economies of scale.
 
    Certain of the companies whose assets were recently acquired by affiliated
physician organizations have recently or historically operated at a loss. Other
acquired companies have experienced fluctuations in quarter-to-quarter operating
results. See "--Fluctuations in Quarterly Results." The Company has commenced
the institution of certain measures intended to reduce any operating losses and
to operate the acquired businesses profitably. However, there can be no
assurance that the Company will reverse these trends or operate these assets
profitably. If there are continuing operating losses from the acquired assets,
the Company may need additional capital to fund its business, and there can be
no assurance that such additional capital can be obtained at all or, if
obtained, that it will be on terms acceptable to the Company.
 
    The Company and its affiliated physician organizations are regularly in
discussions with potential acquisition candidates and may from time to time
enter into letters of intent or definitive agreements with respect to the
acquisition of such businesses. No assurance can be given as to the Company's or
the affiliated physician organizations' ability to identify suitable acquisition
candidates, to compete successfully at favorable prices for available
acquisition candidates or to complete future acquisitions, or as to the
financial effect on the Company of any acquired business. Future acquisitions by
the Company may involve the issuance of additional shares of common stock, which
could have a dilutive effect on earnings per share, or could involve significant
cash expenditures and may result in increased indebtedness and interest and
amortization expenses or decreased operating income, which could have an adverse
impact on the Company's future operating results.
 
    There can be no assurance that the Company and/or its affiliated physician
organizations will be able to achieve and manage its planned growth or that
suitable physician organizations will continue to be
 
                                       9
<PAGE>
available for affiliation upon terms satisfactory to the Company, if at all. In
addition, there can be no assurance that the Company will be able to continue to
attract and retain a sufficient number of qualified physicians and other health
care professionals to continue to expand its operations or otherwise to maintain
an adequate infrastructure to support continued growth. Any failure of the
Company to consummate economically feasible acquisitions, effectively integrate
acquisitions or price services appropriately could have a material adverse
effect on the Company's growth, financial condition and results of operations.
 
    The integration of acquired entities also requires the dedication of
management resources, which may distract the attention of management from the
day-to-day business of the combined companies. Furthermore, new acquisitions may
expose the Company's service network to new payors and providers with which it
has had no previous business experience. The Company cannot predict whether it
will be able to enroll into the Company's service network all members currently
served by physicians affiliated with newly acquired entities. Also, there can be
no assurance that there will not be substantial unanticipated costs or other
material adverse effects associated with acquisition and integration activities,
any of which could result in significant one-time charges to earnings or
otherwise adversely affect the Company's operating results.
 
    To establish a health plan to provide hospital, physician and ancillary
health care services to commercial and Medicare enrollees and thereby accept
full financial risk for the provision of hospital as well as physician and
ancillary health care services, the Company or an affiliated physician
organization will need to obtain a license under the State of California
Knox-Keene Health Care Service Plan Act of 1975 ("Knox-Keene") which Act is
administered by the State of California Department of Corporations ("DOC").
Further, in order to accept full risk for Medicare beneficiaries, in addition to
a Knox-Keene license, the Company or its affiliated physician organization or
organizations will need to obtain certification as a Medicare Health Plan from
HCFA. There can be no assurance that the Company and/or its affiliated physician
organizations will be able to obtain the necessary licenses or certifications to
operate as a health plan with a limited license or as a Medicare Health Plan.
The application process to obtain such licenses and/or certifications is also
time-consuming and expensive.
 
    Even if the Company obtains a limited license under Knox-Keene to operate as
a health plan, the Company will need to enter into agreements with
fully-licensed HMOs to provide hospital, physician and ancillary health care
services to commercial and/or Medicare enrollees. The Company cannot predict
which, if any, HMOs will be willing or able to enter into agreements with the
Company pursuant to which the Company or an affiliated physician organization
would assume full risk for all hospital, physician and ancillary health care
services or if any such agreements will be available on terms acceptable to the
Company. Even if the necessary licenses and certifications to form a Medicare
Health Plan are obtained, the Medicare Health Plan will need to enter into one
or more agreements with HCFA to provide health care services to Medicare
beneficiaries. There also can be no assurance that the Medicare Health Plan will
be able to enter into one or more contracts with HCFA to assume full risk for
all health care services provided to Medicare beneficiaries or if any such
contracts will be available on terms acceptable to the Company. There can be no
assurance that the Company or an affiliate, as the case may be, will be able to
implement or operate as a health plan with a limited license or as a Medicare
Health Plan. A Medicare Health Plan performs all marketing and sales functions
directed at Medicare beneficiaries. The Company has no experience in direct
marketing or sales to Medicare beneficiaries. There can be no assurance that the
Company will be able to successfully market or sell to Medicare beneficiaries.
There also can be no assurance that, even if the Company or an affiliate
satisfies all of the conditions stated above to assume full risk for all health
care services, the Company will earn a profit or not incur losses from such
operations.
 
    NEED FOR ADDITIONAL CAPITAL.  Implementation of the Company's growth
strategy requires substantial capital resources to permit its affiliated
physician organizations to acquire the assets or stock of additional physician
organizations that specialize in managed care, for the effective integration,
operation, and
 
                                       10
<PAGE>
expansion of affiliated physician organizations, and/or for the acquisition of
related management companies and for the effective integration and operation of
such management companies. Such resources will also be needed to obtain a
limited Knox-Keene license and the certifications required to form a Medicare
Health Plan. The Company may also require working capital in connection with its
ongoing operations.
 
    A portion of the Company's revenues is derived from incentive payments under
HMO agreements that are accrued monthly but are not received until approximately
the third quarter of the calendar year, which is well after the revenue has
accrued. These payments are not always made in a timely manner. Subsequent to
this Offering, the Company anticipates that a renewal or replacement of its
credit facility, including any additional amounts available thereunder, and cash
flows from operations will be sufficient to meet the Company's currently
anticipated acquisition, health plan formation and development, expansion and
working capital needs through September 30, 1999; subsequent to September 30,
1999, the Company anticipates that the capital needed to implement its business
plan may exceed the capital sources described above. To finance its ongoing
capital requirements, the Company may from time to time to issue additional
equity securities or incur additional debt. A greater amount of debt or
additional equity financing could be required to the extent that the Company's
Common Stock fails to maintain a market value sufficient to warrant its use in
future acquisitions or to the extent that physician organizations are unwilling
to accept Common Stock in exchange for their operating assets or common stock.
Pursuant to the Company's agreements with the Representative, the Company's
ability to issue any securities is restricted for a period commencing in March
1998 and ending twelve months following the effective date of the Registration
Statement of which this Prospectus forms a part (the "Effective Date"), except
for certain specified purposes, which purposes include acquisitions. See
"--Shares Eligible for Future Sale" herein for further discussion. The Company's
ability to issue any convertible debt or equity securities in a public or
private sale may also be restricted under certain circumstances pursuant to
contractual restrictions in the Company's agreements with its commercial lender.
There can be no assurance that the Company will be able to obtain additional
required capital on terms acceptable to the Company, if at all. Any additional
capital could result in increased indebtedness and interest and financing
expense, decreased operating income to fund future expansion and dilution of the
existing equity owners. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations--Liquidity and Capital Resources."
 
    CURRENT FINANCING ARRANGEMENTS.  The Company currently has a revolving
credit facility with Imperial Bank, a California banking corporation (the
"Bank"). The maximum amount available to the Company under the credit facility
is $12,500,000. The credit facility matures on July 3, 1999. The Company
currently intends to renegotiate the terms of or replace its credit facility
upon maturity. There can be no assurance that the Company will be able to
renegotiate the terms of or replace the credit facility or that any renegotiated
or replacement financing can be obtained on terms acceptable to the Company.
 
    HIGH CONCENTRATION OF HMO CONTRACTS; SHORT-TERM NATURE OF HMO CONTRACTS.  In
the current fiscal year, based on revenues for the nine-month period ended June
30, 1998, the Company anticipates that contracts with three HMOs will account
for approximately 70% of the Company's revenue, of which the contracts with
PacifiCare of California/FHP, Inc. will account for approximately 50% of the
Company's revenue, the contracts with Cigna Healthcare of California, Inc. will
account for slightly less than 10% of the Company's revenue and the contract
with Blue Cross of California will account for slightly more than 10% of the
Company's revenue. HMO contracts generally are for one-year terms, may be
terminated earlier without cause upon notice and upon renewal and are subject to
annual negotiation of capitation rates, covered benefits and other terms and
conditions. At times, HMO contracts may be continued on a month-to-month basis
while the parties renegotiate the terms of the contracts. There can be no
assurance that any of such contracts will not be terminated, will be renewed or,
if renewed, that they will contain favorable terms. The loss of any HMO contract
and the failure to regain or retain such HMO's members or the related revenues
could have a material adverse effect on the Company.
 
                                       11
<PAGE>
    RELIANCE ON GOVERNMENT SPONSORED HEALTH CARE PROGRAMS.  Although the
Company's affiliated physician organizations do not directly contract with HCFA,
the Company estimates that approximately 35% of the revenues of such affiliated
physician organizations are derived from payments made to their contracting HMOs
under Medicare, Medicaid and other government-sponsored health care programs.
Consequently, any change in the regulations, policies, practices,
interpretations or statutes adversely affecting payments made to HMOs under
these government-sponsored health care programs could adversely affect the
results of operations of the Company.
 
    DEPENDENCE ON HMO MEMBER GROWTH.  The Company is also largely dependent on
the continued increase in the number of HMO members who use its service
networks. This growth may come from affiliation with additional physician
organizations, increased membership in HMOs currently contracting with the
Company through its affiliated physician organizations, additional agreements
with HMOs and development or acquisition of other management companies. There
can be no assurance that the Company will be successful in identifying,
acquiring and integrating additional physician organizations or other management
companies or in increasing the number of enrollees. A decline in membership in
HMOs could have a material adverse effect on the operating results and financial
condition of the Company.
 
    DEPENDENCE ON AFFILIATED PHYSICIAN ORGANIZATIONS.  Substantially all of the
Company's revenues are derived from management agreements with its affiliated
physician organizations. The Company's management agreements are for a term of
30 years with additional renewal terms of 10 years and may be terminated only
for cause. Physicians are employed by the affiliated medical groups (and not by
the Company) pursuant to employment agreements with initial terms ranging from
three to seven years. The Company's affiliated independent practice associations
generally contract with independent physicians pursuant to provider agreements
with a term of one year, terminable by either party upon 30 days' (for primary
care physicians) or 90 days' (for specialty care physicians) notice. Key members
of a physician organization could retire, become disabled, terminate their
employment agreements or provider contracts, or otherwise become unable or
unwilling to continue generating revenues at the current level or practicing
medicine within such physician organization. There can be no assurance that (i)
physicians presently in the Company's affiliated physician organizations will
not leave such physician organizations and that enrollees served by such
physicians will not enroll in an unaffiliated physician organization, (ii) the
Company will be able to attract additional physicians into its affiliated
physician organizations, or (iii) the amount of capitation and risk-sharing
payments to such physicians will not have to be increased. In addition, each of
the Company's affiliated physician organizations operates within a limited
geographic area, and a deterioration of economic or other conditions within such
area could have a material adverse impact upon the Company. Any material decline
in revenue of the Company's affiliated physician organizations, whether as a
result of physicians leaving the affiliated physician organizations or
otherwise, could have a material adverse effect on the Company.
 
    The Company's affiliated independent practice associations seek to include
exclusivity and non-diversion arrangements with contracting physicians in their
agreements. In an exclusivity agreement generally, a contracting physician
agrees to refrain from providing physician services to members of HMOs except
through Company-affiliated physician organizations. Under a non-diversion
agreement, a physician is required to refrain from diverting enrollees in a
Company-affiliated independent practice association to an independent practice
association unaffiliated with the Company. Although the affiliated independent
practice associations have entered into exclusivity and/or non-diversion
agreements of varying degrees with certain physicians, there can be no assurance
as to the enforceability of such restrictive agreements. There can also be no
assurance that the affiliated independent practice associations will be able to
enter into additional exclusivity arrangements. In addition, the affiliated
independent practice associations do not have exclusivity and/or non-diversion
agreements with a substantial number of the contracting physicians.
 
                                       12
<PAGE>
    RECENT SETTLEMENT AGREEMENT WITH YORBA LINDA MEDICAL GROUP.  Certain
physicians who are employed by Yorba Linda Medical Group have provided medical
services to enrollees of an affiliated physician organization, Prospect Medical
Group, under separate provider agreements. Under the agreements between these
physicians and Prospect Medical Group, these physicians had agreed to be
exclusive providers for Prospect Medical Group. These physicians sought release
from the exclusivity and other noncompetition provisions in their agreements
with Prospect Medical Group in order to join another physician organization. As
described under "Business of the Company--History of the Company," the Company
and Prospect Medical Group have agreed to the release in exchange for the return
of 1,126,323 shares of Common Stock of the Company pursuant to a settlement
agreement (the "Yorba Linda Settlement Agreement"). The Board of Directors of
the Company believed that the return of the Common Stock constituted adequate
consideration for the release of such physicians from their agreements. The
Company estimates that no more than approximately 13,000 of the Company's
enrollees who were served by these physicians as of June 30, 1998 may enroll
with an unaffiliated physician organization, that any such change in enrollment
would occur by October 1, 1998 and that the loss of these enrollees could reduce
the Company's capitation revenues by no more than 16%, or total revenues by no
more than 15% based on the results of operations for the nine months ended June
30, 1998. Management of the Company believes these reductions in revenue will
not materially adversely affect the Company's business, operations, financial
condition or cash flows because the costs associated with this revenue were
relatively higher than the costs associated with the Company's other revenue.
See "Unaudited Pro Forma Financial Information" herein for a description of the
anticipated effect of the Yorba Linda Settlement Agreement on the results of
operations, financial condition or cash flows of the Company.
 
    HIGHLY COMPETITIVE MARKET.  The managed care industry is highly competitive
and is subject to continuing changes with respect to the manner in which
services are provided and how providers are selected and compensated. The
Company competes with any entity that contracts with HMOs and other payors for
the provision of prepaid health services, including but not limited to: (i)
other companies that provide management services to health care providers; (ii)
hospitals that affiliate with one or more medical groups; (iii) HMOs that employ
or contract directly with physicians; and (iv) other physician organizations.
Additionally, the physician organizations with which the Company is affiliated
compete with other medical groups and independent practice associations in the
areas in which the Company does business, or is expected to do business in the
future. Pressures to reduce the cost of medical care, through legal reform of
the health care system or through market forces such as the continued expansion
of managed care, could adversely impact the Company's revenues. Further,
increased enrollment in prepaid plans because of health care reform or for other
reasons, increased participation by physicians in group practices and other
factors may attract new entrants into the managed care industry and result in
increased competition for the Company. Certain of the Company's competitors are
significantly larger and better capitalized, provide a wider variety of
services, may have more experience in providing health care management services
and may have longer established relationships with HMOs. There can be no
assurance that the Company will be able to compete effectively with such
competitors, that additional competitors will not enter the market or that such
competition will not make it more difficult to enter into affiliations with
physician organizations on terms beneficial to the Company, if at all. See
"Business of the Company--Competition."
 
    DEPENDENCE ON INFORMATION SYSTEMS.  New systems are critical to developing
and implementing operational, financial and disease management information. To
develop its network, the Company has invested in a sophisticated management
information system. See "--Year 2000 Risks" and "Management's Discussion and
Analysis of Financial Condition and Results of Operations." The Company may
experience unanticipated delays, complications and expenses in implementing,
integrating and operating such systems. Furthermore, such systems may require
modifications, improvements or replacements as the Company expands and as new
technologies become available. See "Management's Discussion and Analysis of
 
                                       13
<PAGE>
Financial Condition and Results of Operations--Liquidity and Capital
Resources--Year 2000" for a discussion of the effects of the year 2000 on the
Company's management information systems. Such modifications, improvements or
replacements may require substantial expenditures and may require interruptions
in operations during periods of implementation. Moreover, implementation of such
systems is subject to the availability of information technology and skilled
personnel to assist the Company in creating and implementing the systems. No
assurance can be given that the Company will be able to enhance existing and/or
implement new information systems. The failure to successfully implement and
maintain operational, financial and clinical information systems would have a
material adverse effect on the Company. See "Business of the Company--Strategy
of the Company."
 
    DEPENDENCE ON KEY PERSONNEL.  The Company's future success depends on the
services of its key management personnel, who include Jacob Y. Terner, M.D. and
Gregg DeNicola, M.D. The loss of either of these individuals, or the inability
to attract and retain a sufficient number of qualified management personnel,
could have a materially adverse effect on the Company's results of operations.
Currently, the Company maintains no life insurance on its key management
personnel.
 
    RISKS INHERENT IN PROVISION OF MEDICAL SERVICES.  Each of the affiliated
physician organizations is involved in the delivery of health care services to
the public and, therefore, is exposed to the risk of professional liability
claims. Each of the affiliated physician organizations' contracts with HMOs
generally require such physician organizations to indemnify the HMO for losses
resulting from the negligence of physicians who were employed by or contracted
with the physician organization. Claims of this nature, if successful, could
result in substantial damage awards to the claimants, which may exceed the
limits of any applicable insurance coverage. Insurance against losses related to
claims of this type can be expensive. Moreover, in recent years, physicians,
hospitals and other participants in the health care industry have become subject
to an increasing number of lawsuits alleging medical malpractice and related
claims based on the withholding of approval for or reimbursement of necessary
medical services. Many of these lawsuits involve large claims and substantial
defense costs. Although the Company does not engage in the practice of medicine
or the provision of medical services, there can be no assurance that the Company
will not become involved in such litigation in the future. The Company and its
affiliated physician organizations are currently insured under policies which
cover general and professional liability (including malpractice) and directors'
and officers' liability insurance on a "claims made" basis in amounts deemed
appropriate by management, based upon historical claims and the nature and risk
of its business. In addition, the affiliated independent practice association
provider contracts with physicians typically require each physician to maintain
professional liability insurance coverage of the physician and of each employee,
servant and agent of the physician. There can be no assurance, however, that
future claims will not exceed the limits of available insurance coverage, that
existing insurers will remain solvent and able to meet their obligations to
provide coverage for any such claims, or that such coverage will continue to be
available or available with sufficient limits and at reasonable cost to
adequately and economically insure the Company's and affiliated physician
organizations' operations in the future. A judgment against the Company or any
of its affiliated physician organizations could have a material adverse effect
on the Company.
 
    FULL RISK CAPITATION.  Under all current HMO contracts, the affiliated
physician organizations accept the financial risk for the provision of physician
(including certain specialty care physician) services and certain ancillary
health care services. Pursuant to the Company's future growth strategy, the
Company or an affiliated entity may also accept the financial risk for hospital
services. In the event that (i) the Company is unable to negotiate favorable
prices or rates in contracts with providers of these services on behalf of
itself or its affiliate, or (ii) the affiliated physician organizations are
unable to effectively control the utilization of these services, the Company
could experience material adverse effects on its results of operations.
 
    FLUCTUATIONS IN QUARTERLY RESULTS.  The Company's financial statements
(including interim financial statements) contain accruals which are calculated
quarterly for estimates of incentive payments to be made
 
                                       14
<PAGE>
by the HMOs to the affiliated physician organizations based upon a comparison of
specialist and hospital utilization to budgeted costs. Quarterly results have in
the past and may in the future be affected by adjustments to such estimates for
actual costs incurred. Historically, the affiliated physician organizations and
HMOs generally reconcile differences between actual and estimated amounts
receivable or payable relating to HMO incentive payment arrangements by the
third quarter of each calendar year. In the event that the affiliated physician
organizations and HMOs are unable to reconcile such differences, extensive
negotiation, arbitration or litigation relating to the final settlement of these
amounts may occur. Any delay in the settlement of these amounts may result in an
inability of the Company to record anticipated income. As the Company's network
expands to include additional HMOs, the timing of these reconciliations may
vary; this variation in timing may cause the Company's results not to be
directly comparable to corresponding quarters in other years. The Company's
financial statements also include estimates of costs for covered medical
benefits incurred by enrollees, which costs have not yet been reported by the
providers. While these estimates are based on information available to the
Company at the time of calculation, actual costs may differ from the Company's
estimates of such amounts. If the actual costs differ significantly from the
amounts estimated by the Company, adjustments will be required and quarterly
results may be affected. Quarterly results may also be affected by movements of
HMO members from one HMO to another, particularly during periods of open
enrollment for HMOs. Additionally, the Company, through the affiliated physician
organizations, anticipates making acquisitions in the future. Such acquisitions
could cause fluctuations in the Company's quarterly results. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
    YEAR 2000 RISKS.  The Company is seeking to ensure that its electronic data
processing systems, including any embedded systems that control equipment, will
recognize the year 2000 and will not treat any date after December 31, 1999 as a
date during the twentieth century. See "Management's Discussion and Analysis of
Financial Condition and Results of Operations--Liquidity and Capital
Resources--Year 2000." However, no assurances can be given that the Company will
be able to avoid all year 2000 problems, especially those that could originate
with third parties with whom the Company engages in electronic transactions or
otherwise does business. If the Company or any third party with whom the Company
does business were to have a year 2000 problem, the Company's business could be
seriously disrupted and the Company's financial condition and results of
operations could be materially adversely affected.
 
    RISK RELATED TO INTANGIBLE ASSETS AND AMORTIZATION OF GOODWILL.  The Company
has a significant amount of intangible assets. As a result of acquisitions,
intangible assets (net of accumulated amortization) of approximately $18,588,000
have been recorded in the Company's balance sheet as of June 30, 1998.
Additional acquisitions will result in the recognition of additional intangible
assets which will cause a further increase in amortization expense. Further, any
future determination that a significant impairment of the value of acquired
intangible assets has occurred would require the write-down of the impaired
portion of unamortized goodwill to fair value, which would have a material
adverse effect on the Company's results of operations. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations."
 
    GOVERNMENT REGULATION.  The activities currently conducted by the Company
and its affiliated physician organizations are subject to extensive regulation
at the local, state, and federal levels. The Company believes its operations are
in material compliance with applicable laws. However, the assortment of laws and
regulations affecting the Company's business are complex, in many cases
ambiguous and many provisions have not been the subject of regulatory or
judicial interpretation. There can be no assurance that a review of the
Company's business by courts or regulatory authorities will not result in a
determination that the Company has not complied fully with all applicable laws
and regulations in one or more aspects of its business which could adversely
affect the operations of the Company. Further, there can be no assurance that
the health care regulatory environment will not change so as to restrict the
Company's existing operations or their expansion. See "Business of the
Company--Governmental Regulation."
 
                                       15
<PAGE>
    In California, and in certain other states in which the Company may attempt
to conduct business in the future, general business corporations are not
permitted to practice medicine, exercise control over physicians who practice
medicine or engage in certain practices such as fee-splitting with physicians.
The statutory prohibitions against the corporate practice of medicine generally
proscribe lay entities from employing or hiring health care practitioners, or
from otherwise interfering directly or indirectly with a health care
practitioner's practice of medicine. The Company believes that it is not engaged
in the corporate practice of medicine as it neither represents to the public
that it offers medical services nor purports to control the practice of
medicine. Further, although the Company provides the affiliated physician
organizations with administrative, management and support services, the
affiliated physician organizations continue to be exclusively in control of and
responsible for all aspects of the practice of medicine and delivery of medical
services. The Company's agreements with its affiliated physician organizations
specifically reserve to the physicians exclusive authority to make all decisions
regarding medical care, including the right to employ physicians or enter into
contracts for the provision of medical services or make other financial
commitments. See "Business of the Company--The Affiliated Physician
Organizations." There can be no assurance, however, that regulatory authorities,
courts or parties with which the Company does business will not assert that the
Company is engaged in the corporate practice of medicine and seek relief
prohibiting the Company from carrying on business or voiding existing
contractual relationships. If such assertions are made, the Company might be
required to restructure its contracts with HMOs or with its affiliated physician
organizations. Any such restructuring could have a material adverse effect on
the Company.
 
    The Company is subject to federal legislation that prohibits activities and
arrangements that provide kickbacks or other economic inducements for the
referral of business under the Medicare and Medicaid programs. "Safe harbor"
regulations have been promulgated to identify certain business and payment
practices which are deemed not to violate this legislation. In addition, federal
legislation (known as Stark II) currently restricts the ability of physicians to
refer Medicare/Medicaid patients to entities providing certain designated health
services if the physician has an ownership interest or compensation arrangement
in such entity. Non-compliance with either the federal anti-kickback legislation
or the federal self-referral prohibition can result in exclusion from the
Medicare and Medicaid programs and civil and criminal penalties. In addition,
with respect to the self-referral prohibition, the entity and the referring
physician are prohibited from receiving reimbursement for services rendered.
Many states, including California, have similar anti-kickback and self-referral
laws which provide for similar penalties. Although the Company believes that its
operations comply with all federal and state anti-kickback and self-referral
laws, no assurances can be given that the Company's operations fall outside the
scope of these prohibitions. Further, there can be no assurance that the Company
will be able to comply with any prospective legislation which may be enacted to
regulate the health care industry. See "Business of the Company-- Governmental
Regulation."
 
    In April 1998, the Office of the Inspector General of the Department of
Health and Human Services (the "OIG") issued an advisory opinion under the
Medicare/Medicaid anti-kickback statute with respect to compensation
arrangements in a proposed management services agreement between a medical
practice management company and a primary care physician practice. Based upon
such advisory opinion, the Company has revised its standard management agreement
with its affiliated physician organizations to specify a flat fee payable on a
monthly basis as compensation for marketing services. However, no assurance can
be given that the OIG or any other health care regulatory agency will not
interpret the Company's compensation arrangements to be in violation of the
prohibitions of the anti-kickback statute. See "Business of the
Company--Governmental Regulation."
 
    There are also state and federal civil and criminal statutes imposing
substantial penalties, including civil and criminal fines and imprisonment, on
health care providers that fraudulently or wrongfully bill governmental or other
third-party payors for health care services. The federal law prohibiting false
billings allows a private person to bring a civil action in the name of the
United States government for violations of its provisions. The Company believes
it is in material compliance with such laws, but there is no assurance
 
                                       16
<PAGE>
that the Company's activities will not be challenged or scrutinized by
governmental authorities. Moreover, technical Medicare and other reimbursement
rules affect the structure of physician billing arrangements. The Company
believes it is in material compliance with such regulations, but regulatory
authorities may differ and in such event the Company may have to modify its
physician billing arrangements. Non-compliance with such regulations may
adversely affect the operation of the Company and subject it to penalties and
additional costs.
 
    INACTIVE PRIOR MARKET FOR THE COMMON STOCK; NO ASSURANCE OF AMERICAN STOCK
EXCHANGE LISTING.  Prior to the Offering, the Company's Common Stock has been
the subject of limited and sporadic trading on the OTC-Bulletin Board. The
Company intends to apply to list the Shares and the Warrants on the American
Stock Exchange under the proposed symbols "PXX" and "PXX.W," respectively. No
assurance can be given that such application will be granted or, if granted,
that an active trading market will develop. See "Price Range of Common Stock and
Dividend Policy." There can be no assurance that an active trading market, if
developed, will be sustained.
 
    The Board of Governors of the American Stock Exchange, Inc. has established
certain standards for the initial listing and continued listing of a security on
the American Stock Exchange. The standards for initial listing require, among
other things, that an issuer have a three-year history of operations; minimum
public distribution of 500,000 shares together with a minimum of 800 public
holders or 1,000,000 shares together with a minimum of 400 public holders, and
stockholders equity of at least $4,000,000; the minimum bid price for the listed
securities be $3.00 per share; and the minimum market value of the public float
(the shares held by non-insiders) be at least $15,000,000. The maintenance
standards require, among other things, that an issuer maintain a minimum market
value of its public float of at least $1,000,000, a minimum public distribution
of 200,000 shares and a minimum of 300 holders and comply with certain filing
requirements of the American Stock Exchange. There can be no assurance that the
Company will continue to satisfy the requirements for maintaining an American
Stock Exchange listing. If the Company's securities were to be de-listed from
the American Stock Exchange, it would adversely affect the prices of such
securities and the ability of holders to sell them, and the Company would be
required to comply with the initial listing requirements to be relisted on the
American Stock Exchange.
 
    DETERMINATION OF OFFERING PRICE; POSSIBLE VOLATILITY OF STOCK PRICE.  The
Offering Price of the Common Stock and the Warrants has been established by
negotiation between the Company and the Representative of the Underwriters and
may not be indicative of the prices that will prevail in the public market. See
"Underwriting." There has been a history of significant volatility in the market
prices for shares of health care companies and smaller capitalization companies
generally, and it is likely that the market price of the Common Stock will be
highly volatile. There can be no assurance that shares of Common Stock or the
Warrants may be resold at or above the Offering Price after this Offering.
Prices for the Common Stock and the Warrants following this Offering may be
influenced by many factors, including announcements of legislation or regulation
affecting the health care industry in general and reimbursement for health care
services in particular, the depth and liquidity of the market for the Common
Stock and the Warrants, investor perception of the Company and fluctuations in
the Company's operating results and market conditions.
 
    RISK OF LOW-PRICED SECURITIES; RISK OF APPLICATION OF PENNY STOCK RULES.  If
the Company is unable to satisfy the American Stock Exchange's listing and/or
maintenance requirements, the Common Stock would remain on, or return to, as the
case may be, the OTC Bulletin Board, a screen-based electronic bulletin board
maintained by the National Association of Securities Dealers, Inc. If the price
per share were to drop below $5.00, then unless the Company satisfied certain
net asset tests, the Company's securities would become subject to certain penny
stock rules promulgated by the Securities and Exchange Commission (the
"Commission"). The penny stock rules require a broker-dealer, prior to a
transaction in a penny stock not otherwise exempt from the rules, to deliver a
standardized risk disclosure document prepared by the Commission that provides
information about penny stocks and the nature and level of risks in the penny
stock market. The broker-dealer also must provide the customer with current bid
and offer quotations for
 
                                       17
<PAGE>
the penny stock, the compensation of the broker-dealer and its salesperson in
the transaction and monthly account statements showing the market value of each
penny stock held in the customer's account. In addition, the penny stock rules
require that prior to a transaction in a penny stock not otherwise exempt from
such rules, the broker-dealer must make a special written determination that the
penny stock is a suitable investment for the purchaser and receive the
purchaser's written agreement to the transaction. These disclosure requirements
may have the effect of reducing the level of trading activity in the secondary
market for a stock that becomes subject to the penny stock rules. If the Common
Stock becomes subject to the penny stock rules, investors in the Offering may
find it more difficult to sell their shares.
 
    SPECULATIVE NATURE OF WARRANTS.  The Warrants do not confer any rights of
Common Stock ownership on their holders, such as voting rights or the right to
receive dividends, but rather merely represent the right to acquire shares of
Common Stock at a fixed price for a limited period of time. Following the
completion of this Offering, the market value of the Warrants will be uncertain
and there can be no assurance that the market value of the Warrants will equal
or exceed their initial public offering price. There can be no assurance that
the market price of the Common Stock will ever equal or exceed the exercise
price of the Warrants, and consequently, whether it will ever be profitable for
holders of the Warrants to exercise the Warrants.
 
    POTENTIAL ADVERSE EFFECT OF REDEMPTION OF WARRANTS.  Commencing       , 1999
[the first anniversary of the effective date of the registration statement filed
with respect to the Securities], the Warrants are subject to redemption by the
Company at $.10 per Warrant on thirty days' prior written notice to the warrant
holders if the average closing sales price of the Common Stock as reported on
the American Stock Exchange equals or exceeds $18.00 per share of Common Stock
for any twenty (20) trading days within a period of thirty (30) consecutive
trading days ending on the fifth trading day prior to the date of the notice of
redemption. If the Warrants are redeemed, holders of the Warrants will lose
their rights to exercise the Warrants after the expiration of the 30-day notice
of redemption period. Upon receipt of a notice of redemption, holders would be
required to: (i) exercise the Warrants and pay the exercise price at a time when
it may be disadvantageous for them to do so; (ii) sell the Warrants at the
current market price, if any, when they might otherwise wish to hold the
Warrants; or (iii) accept the redemption price which is likely to be
substantially less than the market value of the Warrants at the time of
redemption. See "Description of Capital Stock--Warrants."
 
    POTENTIAL ADVERSE EFFECT OF SUBSTANTIAL SHARES OF COMMON STOCK
RESERVED.  The Company has reserved a total of 4,504,559 shares of Common Stock
for issuance as follows: (i) 3,000,000 shares for issuance upon exercise of the
3,000,000 Warrants; (ii) 300,000 shares for issuance upon exercise of the
Representative's Warrants; (iii) 300,000 shares for issuance upon exercise of
the Warrants issuable upon exercise of the Representative's Warrants; (iv)
166,000 shares of Common Stock reserved for issuance pursuant to grants that may
be made under the Company's Stock Option Plan, including but not limited to
55,000 shares of Common Stock reserved for issuance upon exercise of options
granted to two officers of the Company at an exercise price equal to $5.00 per
share; (v) 477,119 shares of Common Stock in the aggregate reserved for issuance
upon exercise of options granted to three current directors and a former
director of the Company at an exercise price equal to $1.25 per share; (vi)
10,000 shares of Common Stock reserved for issuance upon exercise of options
granted to a recently elected director at an exercise price equal to $5.00 per
share, (vii) 35,000 shares of Common Stock reserved for issuance upon exercise
of options granted to the sellers of stock of Sierra Primary Care Medical Group,
A Medical Corporation and Sierra Medical Management, Inc., at an exercise price
equal to $5.00 per share; (viii) 13,635 shares of Common Stock reserved for
issuance upon exercise of warrants granted to certain finders in connection with
the 1996 Merger and related transactions at an exercise price equal to $1.375
per share; (ix) 192,725 shares of Common Stock reserved for issuance upon
exercise of warrants granted to the Company's commercial lender at an exercise
price of $5.00 per share; and (x) 10,080 shares that may be issued to a

The existence of the Warrants, the Representative's Warrants and any other
options or warrants may adversely affect the Company's ability to
 
                                       18
<PAGE>
consummate future equity financings. Further, the holders of such warrants and
options may exercise them at a time when the Company would otherwise be able to
obtain additional equity capital on terms more favorable to the Company. See
"Shares Eligible for Future Sale."
 
    LEGAL RESTRICTIONS ON SALES OF SHARES UNDERLYING THE WARRANTS.  The Warrants
are not exercisable for one year and will not then be exercisable unless, at the
time of the exercise, the Company has a current prospectus covering the shares
of Common Stock issuable upon exercise of the Warrants, and such shares have
been registered, qualified or deemed to be exempt under the securities laws of
the state of residence of the exercising holder of the Warrants.
 
    LACK OF EXPERIENCE OF REPRESENTATIVE.  Securities Capital Trading, Inc., the
Representative, commenced operations in June 1995. The Representative has
co-managed and participated as an underwriter in only two previous public
offerings of securities. Accordingly, the Representative has limited experience
as a co-manager or underwriter of public offerings of securities. In addition,
the Representative is a relatively small firm and no assurance can be given that
the Representative will be able to participate as a market maker of the
Securities. No assurance can be given that any broker-dealer will be a market
maker in any of the Securities. See "Underwriting."
 
    REPRESENTATIVE'S POTENTIAL INFLUENCE ON THE MARKET AND THE COMPANY.  A
significant amount of the Securities offered hereby may be sold to customers of
the Representative. Such customers subsequently may engage in transactions for
the sale or purchase of such Securities through or with the Representative. If
the Representative participates in the market, as a market maker or otherwise,
the Representative may exert a dominating influence on the market, if one
develops, for the Securities described in this Prospectus. Such market making
activity may be discontinued at any time. The price and liquidity of the Common
Stock and the Warrants may be significantly affected by the degree, if any, of
the Representative's participation in such market. In addition, the
Representative may have a continuing influence on the Company through exercise
of the Representative's Warrants. See "Underwriting."
 
    DILUTION.  The Offering Price is substantially higher than the book value
per share of Common Stock. Investors purchasing shares of Common Stock in this
Offering will, therefore, incur immediate, substantial dilution in net tangible
book value of their shares. Substantial additional dilution could result from
the expected issuance of other equity securities of the Company, including
shares issued upon the exercise of currently outstanding options and warrants.
See "Shares Eligible for Future Sale." In addition, the Company's expansion
strategy includes acquisitions of, and affiliations with, physician
organizations and acquisition of related management companies. Such acquisitions
and affiliations may be consummated using newly-issued shares of Common Stock as
consideration. The issuance of additional shares of Common Stock may have a
dilutive effect on the net tangible book value or earnings per share following
such issuance.
 
    SHARES ELIGIBLE FOR FUTURE SALE.  Sales of substantial amounts of Common
Stock in the public market following this Offering could have an adverse effect
on the market price of the Common Stock. Upon completion of the Offering and
after giving effect to the Yorba Linda Settlement Agreement (see "Business of
the Company--History of the Company"), the Company will have outstanding
approximately 7,449,395 shares of Common Stock (7,899,395 shares if the
Underwriters' over-allotment option is exercised in full), of which 3,000,000
shares offered hereby (3,450,000 shares if the Underwriters' over-allotment
option is exercised in full) will be freely tradeable without restriction or
further registration under the Securities Act to the extent they are not held by
"affiliates" of the Company, as that term is defined in Rule 144 ("Rule 144")
promulgated under the Securities Act of 1933, as amended ("Securities Act"). The
remaining 4,449,395 shares of Common Stock outstanding upon completion of the
Offering will be "restricted securities" as that term is defined in Rule 144, of
which 2,597,083 shares will be eligible for resale without restriction in
compliance with Rule 144(k), 1,025,039 shares will be eligible for resale
subject to the manner of sale, volume, notice and current public information
requirements of Rule 144, and 827,273 shares will subsequently become eligible
for resale under Rule 144 upon expiration of their
 
                                       19
<PAGE>
respective one-year holding periods. Additionally, upon completion of the
Offering the Company will have outstanding Warrants, Representative's Warrants
and other options and warrants for the purchase of up to approximately 4,504,559
shares of Common Stock (4,954,559 shares if the Underwriters' over-allotment
option is exercised in full). The existence of a large number of shares eligible
for future sale could have an adverse effect on the Company's ability to raise
additional equity capital or on the price at which such equity capital could be
raised. See "Shares Eligible for Future Sale."
 
    The officers, directors and certain other stockholders of the Company, who
upon completion of the Offering will own in the aggregate 1,649,039 shares of
Common Stock (including all of the shares that will be eligible for resale under
Rule 144 and 624,000 of the shares that will not yet be eligible for resale
under Rule 144 following the Offering) and options and/or warrants to purchase
up to 460,000 shares of Common Stock, are required to agree that they will not,
without the consent of the Underwriters, directly or indirectly, offer, sell,
transfer, pledge, assign, hypothecate or otherwise encumber any of such shares
or securities exercisable or exchangeable for or convertible into shares of
Common Stock, whether or not owned, or otherwise dispose of any interest therein
under Rule 144 promulgated by the Commission or otherwise, for a period of not
less than twelve months following the effective date (the "Effective Date") of
the Registration Statement filed with respect to this Offering (the
"Registration Statement"). In addition, without the consent of the Underwriters,
the Company will not sell or offer for sale any of its securities for a period
commencing on March 24, 1998 through a date twelve months following the
Effective Date, except pursuant to or in connection with (i) the exercise of
options granted by the Company under any incentive stock ownership plan (a
"Plan") authorized by the Company's stockholders, (ii) the exercise of non-Plan
options and warrants granted by the Company prior to March 24, 1998 and/or (iii)
the issuance of shares of Common Stock in transactions involving acquisitions by
the Company of the assets or equity ownership of unrelated business entities.
 
    In connection with obtaining its credit facility, the Company issued to the
Bank warrants to purchase shares of Common Stock of the Company (the "Bank
Warrants"). In the event the Company offers to the Company's shareholders the
right to purchase any securities of the Company, then the holders of the Bank
Warrants are entitled to participate in such rights offering.
 
    Certain holders of warrants to purchase shares of Common Stock have certain
registration rights with respect to such shares and additional shares that may
be issued to such persons upon certain dilutive events (subject to certain
limitations on the numbers of shares such holders are entitled to have
registered under any registration statement).
 
    NO DIVIDENDS.  The Company has never paid cash dividends on its Common Stock
and anticipates that for the foreseeable future, all earnings, if any, will be
retained for the operation and expansion of the Company's business. In addition,
under the Company's credit facility, the Company is prohibited from declaring or
paying any dividends or distributions of earnings to its stockholders. See
"Price Range of Common Stock and Dividend Policy."
 
    ANTI-TAKEOVER EFFECT OF CERTAIN CHARTER AND OTHER PROVISIONS.  The Company's
Certificate of Incorporation and By-laws contain certain provisions that could
have the effect of making it more difficult for a person to acquire, or of
discouraging a third party from attempting to acquire, control of the Company,
including transactions in which stockholders might receive a substantial premium
for their shares over then current market prices, and may limit the ability of
stockholders to approve transactions that they deem to be in their best
interest. The Company's Certificate of Incorporation authorizes the Board of
Directors to issue preferred stock ("Preferred Stock") without stockholder
approval and upon such terms as the Board of Directors may determine. The rights
of the holders of Common Stock will be subject to, and may be adversely affected
by, the rights of the holders of any Preferred Stock that may be issued in the
future. The issuance of Preferred Stock, while providing desirable flexibility
in connection with possible acquisitions and other corporate purposes, could
have the effect of discouraging a person from acquiring a majority of the
outstanding Common Stock of the Company. There are no shares of Preferred Stock
presently
 
                                       20
<PAGE>
outstanding and the Company has no present plans to issue any shares of
Preferred Stock. See "Description of Capital Stock--Preferred Stock." The
Company's Certificate of Incorporation further provides for the classification
of its Board of Directors into three classes, with each class of directors
serving staggered terms of three years. In addition, stockholders do not have
the right (i) to take action by written consent without authorization by a
resolution of the Board of Directors or (ii) to call special meetings of
stockholders. Any amendment to the Company's Bylaws or certain provisions of the
Company's Certificate of Incorporation requires the affirmative vote of the
holders of at least 75% of the outstanding shares of the Company. In addition,
the Company will, upon consummation of this Offering, be subject to the anti-
takeover provision of Section 203 of the Delaware General Corporation Law. In
general, this statute prohibits a publicly held Delaware corporation from
engaging in a "business combination" with an "interested stockholder" for a
period of three years after the date of the transaction in which the person
became an interested stockholder unless such business combination is approved in
the prescribed manner. See "Description of Capital Stock."
 
    Provisions in Dr. DeNicola's employment agreement provide for
post-termination compensation, including payment of his salary for two years,
following a merger or consolidation in which the Company is not the consolidated
or surviving corporation or a transfer of substantially all of the assets of the
Company. See "Management of the Company--Employment Arrangements." A change in
control of the Company also constitutes an event of default under the Company's
credit facility. The foregoing matters may, together or separately, have the
effect of discouraging or making more difficult an acquisition or change of
control of the Company.

                                  THE COMPANY
 
    The Company manages and administers physician organizations (i.e., medical
groups and independent practice associations) that have entered into agreements
with HMOs to provide physician and certain ancillary health care services to HMO
members under capitated or prepaid fee arrangements. Management services are
provided by the Company to each affiliated physician organization pursuant to a
long-term management services agreement. Under this long-term management
services agreement, the Company provides the physician organization with certain
management and administrative support services, such as claims administration,
utilization management and quality assurance, case management, data collection
and management information systems and payor and provider contracting. The
Company also provides its affiliated medical groups with leased premises,
furniture, fixtures, equipment and personnel (which the Company does not provide
to its affiliated independent practice associations, as such associations are
operated as separate businesses with respect to these items). In order to secure
its rights under the management services agreement, the Company enters into an
assignable option agreement with the physician organization which gives the
Company the right to designate the physician or physicians who will own the
physician organization.
 
    Physician organizations increasingly are responding to the cost-containment
pressures within the managed care industry by affiliating with managed care
administrators such as the Company. The Company's management services are
intended to allow affiliated physician organizations to deliver required medical
services in a more cost effective manner. Management believes that cost savings
can be generated without adversely affecting the quality of care provided by the
physician organizations by, for example, managing the risk for hospital services
as well as physician and ancillary health care services, negotiating favorable
HMO and provider contracts, and generating operating efficiencies. The Company's
fee arrangements with affiliated physician organizations are structured so as to
allow the Company to benefit from the savings so obtained.
 
    The Company believes that the managed care industry operates most
effectively on a regional basis, and is affected most by provider competition,
physician referral patterns, custom and practice and local hospital
relationships. Management believes that developing a significant local market
presence permits economies of scale and greater efficiencies through
centralization of operations. Management believes there is more economic
opportunity in developed rather than in undeveloped managed care markets because
(i) physicians and hospitals in developed markets have established practice and
referral patterns that are consistent with providing services within a managed
care framework and (ii) there is generally a higher concentration of physicians
and hospitals in a developed market, creating a more competitive environment
with greater opportunities for the Company and its affiliated physician
organizations to negotiate more favorable provider contracts. The Company has
selected certain counties in Southern California as the initial primary service
area for its operations because management believes that Southern California is
a highly-developed managed care market.
 
    The Company's primary strategy is to grow through acquisition by its
affiliated physician organizations of other medical groups and independent
practice associations. The criteria which the Company has developed to assess
potential acquisition candidates include (i) either a history of profitable
operation or a compelling synergy with opportunities for economies of scale
through combining operations; (ii) either geographic proximity to the Company's
current operations or a material share of the potential acquisition candidate's
own local marketplace; (iii) a favorable hospital relationship; and/or (iv)
willingness of the acquisition candidate's management to continue managing the
acquired entity following its acquisition. The Company is continuously seeking
new acquisition and affiliation candidates as part of its growth strategy. There
can be no assurance that any definitive agreements will be executed or that any
such acquisitions or affiliations will be consummated.
 
    As part of the Company's future growth strategy, the Company through its
affiliated physician organizations intends to seek to provide and manage all
hospital health care services as well as physician and ancillary health care
services to (i) enrollees within the Company's service network and (ii) Medicare
 
                                       22
<PAGE>
enrollees not currently served through the Company's provider network, in each
case in exchange for a monthly per member capitation payment from the respective
payor. To implement this strategy the Company intends to seek to obtain a
license pursuant to California law to contract with HMOs on a full-risk basis
and certification under federal law to form and develop a Medicare Health Plan
to contract with HCFA on a full-risk basis. The ability of the Company and/or
any affiliated physician organization to assume the financial and managerial
responsibility for hospital as well as physician and ancillary health care
services will also require the Company to obtain contracts with fully-licensed
HMOs or HCFA, as applicable. There can be no assurance that any such license or
federal Medicare Health Plan certification can be obtained. See "Risk
Factors--Risks Associated with Growth Strategy."
 
    Since July 1997, Prospect Medical Group has acquired four physician
organizations for the aggregate consideration of approximately $12,700,000 in
cash, plus promissory notes in the aggregate principal amount of $3,000,000 and
the issuance of 800,000 shares of the Company's Common Stock and options to
purchase 35,000 shares of the Company's Common Stock. These acquisitions
increased the Company's service network in Central Orange County and resulted in
the Company managing one of the largest managed care practices in the Antelope
Valley region of Southern California.
 
                                USE OF PROCEEDS
 
    The estimated net proceeds to the Company from the sale of the 3,000,000
shares of Common Stock and Warrants to purchase 3,000,000 shares of Common Stock
offered hereby are $15,524,000 ($17,954,000 if the Underwriters' over-allotment
option is exercised in full), based on an assumed initial public offering price
of $6.00 per share and $0.10 per Warrant and after deducting underwriting
discounts and commissions and costs of the Offering. The Company intends to use
such net proceeds as follows:

- ------------------------
 
(1) The Company intends to use a portion of the proceeds of the Offering to pay
    the outstanding debt under the Company's credit facility provided by its
    commercial lender. Approximately $10,000,000 was drawn under this facility
    by the Company as of June 30, 1998 in connection with the acquisitions of
    Santa Ana/Tustin Physicians Group, Inc., a California professional
    corporation ("Santa Ana/Tustin Physicians Group") and Sierra Primary Care
    Medical Group, A Medical Corporation ("Sierra Medical Group"). See "Business
    of the Company--History of the Company" and "Management's Discussion and
    Analysis of Financial Condition and Results of Operations--Liquidity and
    Capital Resources." Application of proceeds to pay the outstanding balance
    will make funds available under the Company's credit facility for future
    acquisitions. See "Risk Factors--Need for Additional Capital" and "Business
    of the Company--Strategy of the Company." The interest rate on the Company's
    credit facility varies based upon the prime rate plus an applicable margin
    ranging from 50 to 150 basis points. The credit facility matures on July 3,
    1999.
 
(2) The Company intends to apply approximately $2,250,000 (outstanding balance
    at June 30, 1998) of proceeds of the Offering to pay off the outstanding
    principal of two promissory notes issued by Prospect Medical Group to
    acquire Sierra Medical Group and one promissory note issued by the Company
    to acquire Sierra Medical Management and approximately $1,000,000 of
    proceeds of the Offering to pay the cash portion and to pay off the
    principal of a promissory note that the Company
 
                                       23
<PAGE>
    issued in connection with the acquisition of certain assets of PrimeCare
    Medical Group of Antelope Valley, Inc., a California professional
    corporation ("Antelope Valley Medical Group").
 
(3) The Company intends to use approximately $1,100,000 of proceeds of the
    Offering to pay an additional draw under the Company's credit facility that
    was used for working capital.
 
(4) The Company intends to apply approximately $500,000 of proceeds of the
    Offering to pay certain costs associated with the formation and development
    of health plans. See "Business of the Company" and "Management's Discussion
    and Analysis of Financial Condition and Results of Operations." Such costs
    include organizational expenses and initial operating expenses and making a
    deposit into a tangible net equity reserve. The Company intends to use a
    draw on its credit facility to pay for any additional costs which the
    Company currently estimates will total approximately $2,500,000.
 
    Allocation of the net proceeds of this Offering by the Company, as set forth
above, represents the Company's best estimate, based upon its present plans and
certain assumptions regarding general economic and industry conditions. If any
of such plans or assumptions should change, the Company may find it necessary or
advisable to reallocate some of the Offering proceeds within the above-described
categories, or to other purposes.
 
    Pending any of the other uses described above, the Company intends to apply
the net proceeds of the Offering to pay off any outstanding balances under the
Company's credit facility and then to invest any remaining net proceeds in
short-term, investment grade, interest-bearing securities, certificates of
deposit or direct or guaranteed obligations of the United States.
 
                PRICE RANGE OF COMMON STOCK AND DIVIDEND POLICY
 
    Prior to this Offering, Prospect Medical Holdings' Common Stock has been the
subject of limited and sporadic trading on the OTC Bulletin Board, a
screen-based electronic bulletin board maintained by the National Association of
Securities Dealers, Inc. Accordingly, there is no established public trading
market for the Company's Common Stock. See "Risk Factors--Inactive Prior Market
for the Common Stock; No Assurance of American Stock Exchange Listing" and
"Description of Capital Stock--Listing on American Stock Exchange."
 
    As of July 1, 1998, the estimated number of beneficial owners of the
Company's Common Stock was approximately 695 and the number of stockholders of
record was 459. See "The Offering."
 
    No cash dividends have been paid by the Company to date and none is expected
to be paid in the near future. In the event the Company becomes profitable,
management currently is of the view that all earnings will be retained for the
operation and expansion of the Company's business. The future dividend policy of
the Company will be subject to the discretion of its Board of Directors and will
depend upon a number of factors, including future earnings, financial
conditions, cash needs and general business conditions. In addition, under the
Company's credit facility, the Company is prohibited from declaring or paying
any dividends or distributions of earnings to its stockholders. See "Risk
Factors--No Dividends."

this Offering constitutes the dilution to investors in this Offering. Net
tangible book value per share is determined by dividing the net tangible book
value of the Company (total tangible assets reduced by the amount of total
liabilities) by the number of outstanding shares of Common Stock. The following
discussion allocates no value to the Warrants.
 
    The historical net negative tangible book value of the Company at June 30,
1998 was approximately $(13,939,504), or $(2.50) per share of Common Stock
($(13,882,742) or $(3.12) per share of Common Stock after giving effect to the
Yorba Linda Settlement Agreement (see "Risk Factors--Recent Settlement Agreement
with Yorba Linda Medical Group" and "Business of the Company--History of the
Company")). See "Management's Discussion and Analysis of Financial Condition and
Results of Operations-- Liquidity and Capital Resources." After giving effect to
the Offering and the application of the net proceeds from the Offering (with an
initial public offering price of $6.00 per share), the Company's net tangible
book value at June 30, 1998 would have been approximately $1,962,000, or $0.26
per share. This represents an immediate increase in net tangible book value of
$2.76 per share to existing stockholders and an immediate dilution in net
tangible book value of $5.74 per share to new investors purchasing shares of
Common Stock in the Offering. The following table illustrates this per share
dilution:

(1) Assuming the Underwriters' over-allotment option is exercised in full, sales
    of Common Stock by the Company in the Offering will reduce the number of
    shares of Common Stock held by existing stockholders to 56.3% of the total
    number of shares of Common Stock to be outstanding after the Offering, and
    will increase the number of shares held by new investors to 43.7% of the
    total number of shares of Common Stock to be outstanding after the Offering.
    See "Beneficial Ownership of Capital Stock."
 
(2) After giving effect to the reduction of 1,126,323 shares of Common Stock
    outstanding in conjunction with the Yorba Linda Settlement Agreement.
 
(3) The above computations assume no exercise after June 30, 1998 of any of the
    outstanding options and warrants to purchase shares of the Common Stock. As
    of June 30, 1998, there were options and warrants outstanding to purchase a
    total of 783,479 shares of Common Stock at a weighted average exercise price
    of $2.65 per share, all of which were exercisable on such date. To the
    extent that these options and warrants are exercised, there will be further
    dilution to new investors.

                   UNAUDITED PRO FORMA FINANCIAL INFORMATION
 
    The following unaudited pro forma consolidated balance sheet at June 30,
1998 and the unaudited pro forma consolidated statements of operations for the
year ended September 30, 1997 and the nine months ended June 30, 1998 have been
prepared to reflect adjustments to the Company's historical financial position
and results of operations to give effect to the following completed transactions
as if such transactions had been consummated at earlier dates.
 
    Effective July 14, 1997, Prospect Medical Group (an affiliate of the
Company) acquired Santa Ana/ Tustin Physicians Group for cash consideration of
$5,000,000. Effective September 25, 1997 Prospect Medical Group and the Company
acquired Sierra Medical Group and Sierra Medical Management, Inc., respectively,
for consideration totaling $9,000,000 in cash and notes and 600,000 shares of
the Company's common stock and options to purchase 35,000 shares of the
Company's common stock. These two acquisitions resulted in goodwill and other
intangible assets of $5,081,343 and $11,127,000, respectively.
 
    Effective as of June 1, 1998, Sierra Medical Group and the Company acquired
certain assets (primarily management rights and provider contracts) of Antelope
Valley Medical Group and its affiliated management company for $1,000,000 in
cash and notes and 200,000 shares of the Company's common stock. This
acquisition resulted in goodwill and other intangible assets of $2,047,375. None
of the personnel or facilities of Antelope Valley Medical Group or its related
management company were acquired by Sierra Medical Group or the Company. The
general and administrative costs shown in the unaudited pro forma consolidated
statements of operations for the year ended September 30, 1997 and the nine
months ended June 30, 1998 for Antelope Valley Medical Group reflect historical
costs incurred by or on behalf of Antelope Valley Medical Group for the year
ended September 30, 1997 and eight months ended May 31, 1998, respectively. The
Company believes that it will be able to integrate the acquired assets into the
existing operations of its affiliated physician organizations utilizing
personnel and facilities already located and operating in the Antelope Valley
and thereby significantly reduce the general and administrative costs associated
with the operations of the assets acquired from Antelope Valley Medical Group.
Therefore, the Company does not believe that the historical general and
administrative costs of Antelope Valley Medical Group are indicative of the
costs likely to be incurred in future periods. In addition, prior to
acquisition, the former management of Antelope Valley Medical Group had
determined that it could not operate Antelope Valley Medical Group profitably,
and therefore a non-recurring expense totaling $3,168,260 was recorded by the
former management of Antelope Valley Medical Group in the twelve-month period
ended December 31, 1997.
 
    The unaudited pro forma financial information also gives effect to the Yorba
Linda Settlement Agreement. Certain physicians employed by Yorba Linda Medical
Group who have provided physician services to enrollees of Prospect Medical
Group sought release from the exclusivity and other noncompetition provisions in
their agreements with Prospect Medical Group. Effective July 1, 1998, the
Company and Prospect Medical Group entered into the Yorba Linda Settlement
Agreement with these physicians who were also stockholders of the Company.
Pursuant to the Yorba Linda Settlement Agreement, the stockholders returned to
the Company an aggregate of 1,126,323 shares of the Company's common stock that
had been issued to them in connection with the 1996 Merger in exchange for a
release by Prospect Medical Group from the non-competition and exclusivity
provisions contained in their agreements. The Company estimates that a maximum
of approximately 13,000 enrollees who were served by the departing physicians
related to Yorba Linda Medical Group may be transferred from Prospect Medical
Group. The effect of the Yorba Linda Settlement Agreement was to reduce
operating revenues on the pro forma consolidated statements of operations as
compared to the historical consolidated statements of operations. Likewise, the
cost of medical services was reduced on the pro forma consolidated statements of
operations as compared to the historical statements of operations because the
costs associated with providing the medical services to the Yorba Linda Medical
Group enrollees would not have been incurred; however, no other adjustments to
reduce operating expenses, except for an estimate of the costs incurred related
to
 
                                       27
<PAGE>
management fee revenues which will no longer be earned, which might have
resulted from such reduction have been made. See "Risk Factors--Recent
Settlement Agreement with Yorba Linda Medical Group."
 
    The unaudited pro forma consolidated statements of operations for the year
ended September 30, 1997 and the nine months ended June 30, 1998 reflect the pro
forma results of operations of all entities acquired and the impact from the
Yorba Linda Settlement Agreement as if such acquisitions and Settlement
Agreement had been effected as of October 1, 1996.
 
    The pro forma financial information has been prepared by management based on
the historical consolidated audited and unaudited financial statements of the
Company and the affiliated physician organizations as of and for the year ended
September 30, 1997 and as of and for the nine months ended June 30, 1998.
Additional general and administrative expenses, which may have been required to
support the operations of the acquired entities, are not included in the
consolidated pro forma results of operations. The Company and its affiliated
physician organizations have not had any experience prior to June 1, 1998
operating or managing the assets acquired from Antelope Valley Medical Group and
its affiliated management company. These assets will need to be integrated with
those assets currently managed by the Company. Consequently, the Company's
actual results of operations or financial condition may differ from the
information presented in the pro forma financial information as a result of this
acquisition. Similarly, the effect of the Yorba Linda Settlement Agreement on
the Company's actual results of operations or financial condition may differ
from the pro forma financial information since the Company has historically
included the revenues and related expenses derived from the enrollees of Yorba
Linda Medical Group within its affiliated physician organizations' service
network and such enrollees may be transferred from the Company's affiliated
physicians organization in the future. The pro forma financial information is
presented for illustrative purposes and does not purport to represent what the
results of operations or financial condition of the Company for the periods or
at the dates presented would have been if such transactions had been consummated
as of such dates and is not indicative of the results that may be obtained in
the future.
 
    The pro forma statement of operations for the year ended September 30, 1997
also reflects the proposed Offering of Common Stock including the Warrants, at
an assumed initial public offering price of $6.00 per share and $.10 per
Warrant, and gives effect to the receipt and application of the estimated net
proceeds from this Offering, as if such transaction had occurred on October 1,
1996. The pro forma statement of operations for the nine months ended June 30,
1998 also reflects the proposed Offering and gives effect to receipt and
application of the estimated net proceeds from this Offering, including the
repayment of certain indebtedness, as if such transactions had occurred on
October 1, 1997. The pro forma balance sheet as of June 30, 1998 also reflects
the proposed Offering and gives effect to the receipt and application of the
estimated net proceeds from this Offering, as if such transaction had occurred
on June 30, 1998.
 
    The pro forma financial information is based on the financial statements of
the Company, after giving effect to the assumptions and adjustments in the
accompanying notes to the pro forma financial information.

(1) The reductions in revenues related to the Yorba Linda Settlement Agreement
    include primarily lost capitation and shared risk revenues based on the
    estimate of lost enrollees serviced by the specific physicians at their
    capitated rates and revenues under the management agreement with Yorba Linda
    Medical Group. Medical costs and operating expenses are reduced based upon
    the estimated medical loss ratio calculated with respect to the related
    capitation revenue and an adjustment to general and administrative costs
    related to the provision of management services.
 
(2) Assumed aggregate interest costs of $1,206,000 with respect to debt incurred
    related to the three acquisitions made are as follows:
 
     (i) The $5,000,000 debt incurred related to Santa Ana/Tustin Physicians
         Group is for nine and one-half months at an interest rate of 9% per
         annum.

Company. This consolidation is required under EITF Issue No. 97-2, "Application
of FASB Statement No. 94 and APB Opinion No. 16 to Physician Practice Management
Entities and Certain Other Entities with Contractual Management Arrangements"
issued by the Emerging Issues Task Force of the Financial Accounting Standards
Board because the Company is deemed to hold a controlling financial interest in
such organizations through a nominee shareholder. The Company can (through an
assignable option agreement) change the nominee shareholder at will on an
unlimited basis and for nominal cost. There is no limitation on who may be named
by the Company as a nominee shareholder except that such person must be a
licensed physician or otherwise permitted by law to hold shares in a
professional corporation. See "Business of the Company--The Affiliated Physician
Organizations--Management Services" and "Business of the Company--The Affiliated
Physician Organizations--Assignable Option Agreements" for a description of the
management services agreements and assignable option agreements. As a
consequence of this consolidation, the operations of the Company's affiliated
physician organizations have, and will continue to have, a significant impact
upon the Company's financial statements.
 
    On July 31, 1996, a wholly-owned subsidiary of the Company merged into
Prospect Medical Systems in the 1996 Merger, with Prospect Medical Systems being
the surviving corporation and a wholly-owned subsidiary of the Company.
Concurrently with the 1996 Merger, the name of the Company was changed from
Med-Search, Inc. ("Med-Search") to its current name, Prospect Medical Holdings,
Inc. Under applicable financial reporting requirements, Prospect Medical Group,
Inc. (a medical group that is and was affiliated with Prospect Medical Systems
prior to the 1996 Merger) is considered the predecessor entity to the Company
for periods prior to July 31, 1996 for financial statement reporting purposes.
 
    Prospect Medical Group's subsidiaries, Santa Ana/Tustin Physicians Group and
Sierra Medical Group, were acquired on July 14, 1997, and September 25, 1997,
respectively. As of the dates of acquisition by Prospect Medical Group, Santa
Ana/Tustin Physicians Group and Sierra Medical Group had approximately 12,000
and 15,000 covered lives, respectively. Pegasus Medical Group, a wholly-owned
subsidiary of Prospect Medical Group that was formed on November 7, 1996, had no
medical operations until its acquisition of certain assets of Western Medical
Group on October 31, 1997. Based upon the number of lives served by Western
Medical Group on October 31, 1997, this acquisition provided Pegasus Medical
Group with approximately 5,300 covered lives. Sierra Medical Group acquired
certain assets of Antelope Valley Medical Group effective as of June 1, 1998,
including responsibility for approximately 12,000 covered lives. Such
acquisitions have been accounted for under the purchase method of accounting and
the operations of such acquired physician organizations have been included on a
consolidated basis in the
 
                                       33
<PAGE>
Company's financial statements for periods after the effective date of such
acquisitions. Consequently, the Company's financial statements for the fiscal
year ending September 30, 1997 reflect only 2.5 months of the operations of
Santa Ana/Tustin Physicians Group and no operations for either Sierra Medical
Group or Pegasus Medical Group. In addition, the Company's balance sheet as of
September 30, 1997 does not reflect the acquisition of certain assets of Western
Medical Group by Pegasus Medical Group or any assets of Antelope Valley Medical
Group and its related management company. The Western Medical Group acquisition
was not considered material when the determination was made for inclusion of
separate historical financial statements.
 
    The Company's consolidated revenues are composed primarily of (1) monthly
payments (capitation) made by HMOs to the Company's affiliated physician
organizations on behalf of the HMOs' members who have chosen or been assigned to
one of these organizations to provide for the HMOs' members' medical needs under
managed care arrangements, (2) fee-for-service collections generated by the
affiliated physician organizations for medical services provided and (3)
incentive payments made under risk-sharing agreements with HMOs utilizing funds
(i.e. "risk pools" or "bonus pools") withheld or paid by the HMOs to promote and
reward savings obtained through the efficient utilization of medical services.
See "Business of the Company--Managed Care Industry Overview" for a brief
description of such payments. Additional revenues are received by the Company in
the form of management fees from non-affiliated physician organizations.
 
    The Company's consolidated cost of medical services consists largely of (1)
monthly capitation payments to those primary care physicians and specialists
contracting with the affiliated independent practice associations who have
elected that means of compensation, (2) mostly discounted fee-for-service
payments made to non-capitated specialists and other providers of medical
services who are not employed by Prospect Medical Group or its medical group
subsidiaries and (3) salaries, benefits and other compensation paid to
physicians and other medical professionals who are employees of Prospect Medical
Group or its medical group subsidiaries.
 
    In order for the Company to implement its growth strategy, the Company has
been required to invest in the expansion of its operating infrastructure.
Approximately 68 additional persons were hired during the period from April 1,
1997 to March 31, 1998, in part to establish separate departments to manage the
areas of (i) clinical operations, including case management and quality control,
(ii) claims and management information systems operations, (iii) contracting,
and (iv) independent practice association/medical management, including billing
and collecting, practice management, medical staff and provider relations. Each
of these departments operates under the supervision of a vice president; since
March 31, 1998 the Company has not significantly increased the number of its
permanent employees.
 
    Other general and administrative expenses incurred in preparation for
implementation of the Company's growth strategy included investment in advanced
management information systems equipment and increased legal and accounting
costs in connection with the Company's acquisition program. In fiscal year 1998,
Prospect Medical Systems acquired the hardware and software for a sophisticated
management information system at an initial investment of approximately
$1,100,000. The Company currently estimates that the total cost will be expended
in fiscal year 1998. The Company commenced using the new system on September 1,
1998. The Company borrowed approximately $600,000 of the total cost from an
unaffiliated lender under a long-term loan agreement at an interest rate of
10.25% per annum. The Company anticipates that any additional costs that are
incurred to install and implement this system will be paid from cash generated
from operations.
 
RESULTS OF OPERATIONS
 
    Comparison of the Company's historical results of operations for the fiscal
years ended September 30, 1997, 1996 and 1995 and for the nine month periods
ended June 30, 1998 and 1997 will not, in the view of management of the Company,
prove meaningful because of the rapid growth of the Company during such
 
                                       34
<PAGE>
periods and because the affiliation relationships entered into by the Company
during those periods are not reflected in the Company's historical results of
operations for prior periods. Instead, a summary of the elements which
management of the Company believes essential to an analysis of the results of
operations for such periods is presented below.
 
FISCAL YEAR ENDED SEPTEMBER 30, 1997 COMPARED WITH FISCAL YEAR ENDED SEPTEMBER
  30, 1996
 
    The Company's operating revenues increased to $29,955,000 in the fiscal year
ended September 30, 1997 from $24,435,000 in the fiscal year ended September 30,
1996, representing an increase of $5,520,000. Of this increase, $4,355,000
resulted from an increase in capitation revenue to $24,606,000 in the fiscal
year ended September 30, 1997 from $20,251,000 in the fiscal year ended
September 30, 1996. The increase of $4,355,000 in capitation revenues from 1996
resulted from the addition of 13,000 enrollees or approximately $2,555,000 from
internal growth and approximately 27,000 enrollees or approximately $1,800,000
as a result of the acquisitions. As of September 30, 1997, the number of managed
care patients enrolled in the Company's networks totaled approximately 75,000 as
compared to approximately 35,000 at the same date in 1996.
 
    Fee-for-service revenue increased to $1,188,000 during the fiscal year ended
September 30, 1997 from $705,000 during the fiscal year ended September 30,
1996. This increase is primarily the result of an increase in co-payments made
by enrollees under HMO agreements and fees from non-capitated patients.
Fee-for-service revenue as a percentage of operating revenues increased to
approximately 4.0% during the fiscal year ended September 30, 1997 from
approximately 2.9% during the fiscal year ended September 30, 1996. The Company
believes that this percentage will not increase significantly as the Company and
its affiliated physician organizations undertake additional acquisitions.
 
    Incentive payments consist of bonus pool revenue that is paid to affiliated
physician organizations. Bonus pool revenue increased to $2,509,000 during the
fiscal year ended September 30, 1997 from $1,562,000 during the fiscal year
ended September 30, 1996. This increase was due to increased enrollees and
better risk management.
 
    Revenue from management services provided to unaffiliated physician
organizations ("MSO Revenue") increased to $1,429,000 for the fiscal year ended
September 30, 1997 from $945,000 for the fiscal year ended September 30, 1996.
The increase resulted from the Company managing additional unaffiliated
physician organizations during the year ended September 30, 1997. For the fiscal
year ended September 30, 1997, $891,000 of the MSO Revenue and for the fiscal
year ended September 30, 1996, $901,000 of the MSO Revenue was derived from
management services provided to Yorba Linda Medical Group. A portion of such
revenues terminated as of July 1, 1998. See "Risk Factors--Recent Settlement
Agreement with Yorba Linda Medical Group."
 
    The cost of medical services for the fiscal year ended September 30, 1997
was $23,202,000, representing an increase of $3,710,000 from $19,492,000 in the
prior fiscal year. The total cost of medical services increased from fiscal year
1996 to fiscal year 1997 as a result of the increase in the number of enrollees
from the Company's acquisition program and internal growth. The medical loss
ratio (the ratio of the cost of medical services to operating revenues derived
from medical services) was 82.0% and 86.6% for the fiscal years ended September
30, 1997 and 1996, respectively. The decrease in the medical loss ratio from
fiscal year 1996 to fiscal year 1997 resulted from lower medical costs per
enrollee at the acquired physician organizations.
 
    The Company and its affiliates have taken several additional actions since
October 1, 1997 in an attempt to continue to reduce their respective costs.
These actions include closer monitoring of claims authorizations, renegotiation
of contracts for certain specialty and ancillary health care services, including
obstetrics and gynecology, orthopedics, general surgery, outpatient radiology
and physical therapy and entering into new agreements for certain hospital
services and hospital-based physicians. The Company
 
                                       35
<PAGE>
has entered into a lease to consolidate the operations of Santa Ana/Tustin
Physicians Group with certain operations of Prospect Medical Group. The Company
has also entered into a lease to consolidate the management and administrative
functions performed by Prospect Medical Systems for Prospect Medical Group and
Santa Ana/Tustin Physicians Group into a single location on or about the end of
the first quarter of fiscal year 1999.
 
    Gross margin for the fiscal year ended September 30, 1997 increased to
$6,753,000 from $4,943,000 for the prior fiscal year, representing 22.5% and
20.2% of total operating revenues for the fiscal years ended September 30, 1997
and 1996, respectively. The increase in gross margin resulted from a larger
increase in total operating revenues than the increase in the cost of medical
services as a result of lower medical costs per enrollee at the acquired
physician organizations.
 
    General and administrative expenses for the fiscal year ended September 30,
1997 rose to $7,300,000 from $4,212,000 for the preceding fiscal year,
representing 24% and 17% of gross revenues for the respective year. The largest
component of such costs is non-physician salaries and benefits. Salaries and
benefits increased to $4,318,000 during the fiscal year ended September 30, 1997
from $2,559,000 during the fiscal year ended September 30, 1996, an increase of
69%. This increase resulted from the increase in the number of management
personnel hired in preparation for implementation of the Company's growth
strategy and cost containment programs.
 
    Other general and administrative expenses incurred in preparation for
implementation of the Company's growth strategy included employee training in
connection with investment in advanced management information systems equipment,
and increased legal and accounting costs. Physician office expenses increased to
$869,000 during the fiscal year ended September 30, 1997 from $696,000 during
the fiscal year ended September 30, 1996. This increase is primarily the result
of additional offices for the medical groups acquired pursuant to the Company's
acquisition program. Other operating expenses increased to $2,113,000 during the
fiscal year ended September 30, 1997 from $957,000 during the fiscal year ended
September 30, 1996, an increase of 121%. This increase is primarily the result
of the Company's acquisition program and an increase in personnel support.
 
    Depreciation and amortization rose to $244,000 for the fiscal year ended
September 30, 1997 as compared to $102,000 for the fiscal year ended September
30, 1996.
 
    The acquisition of the stock of Santa Ana/Tustin Physicians Group, Sierra
Medical Group and Sierra Medical Management (and certain assets of Western
Medical Group and Antelope Valley Medical Group) and related entities have been
accounted for by the Company using the purchase method of accounting, under
which the Company records as goodwill the excess of the purchase price over the
fair value of the net tangible assets of the acquired businesses. As of
September 30, 1997, the Company's total consolidated assets were approximately
$24,511,000, of which approximately $16,530,000, or 67.4% was goodwill. Goodwill
is being amortized on a straight-line basis over a 20 year period.
 
    Substantially all of the goodwill on the Company's consolidated balance
sheet as of September 30, 1997 is related to acquiring the stock of Santa
Ana/Tustin Physicians Group, Sierra Medical Group and Sierra Medical Management.
The Company evaluates each acquisition and establishes an appropriate
amortization period based on the underlying facts and circumstances. Currently,
the Company uses 20 years based on a preliminary allocation of the estimated
fair values of the net assets acquired. Subsequent to each acquisition, the
Company will reevaluate such facts and circumstances to determine if the related
goodwill continues to be realizable and if the amortization period continues to
be appropriate.
 
    Amortization of goodwill for the fiscal year ended September 30, 1997 was
$49,000. In addition, during the fiscal year ended September 30, 1997 the
Company voluntarily terminated one HMO contract related to the provider network
acquired in the 1996 Merger because the capitation payments made under this
contract were not sufficient to cover the cost of medical services provided
thereunder. This HMO contract was the primary asset acquired in that
transaction. Consequently, all intangible assets acquired
 
                                       36
<PAGE>
from Med-Search were considered impaired and of no continuing value. To reflect
this asset impairment, a loss totaling $2,197,000 was recorded in the fiscal
year ended September 30, 1997.
 
    Affiliations with additional physician organizations which result in the
recognition of additional goodwill would cause amortization expense to increase
further. Any future determination that a significant impairment has occurred
would require the write-down of the impaired portion of unamortized goodwill to
fair value, which would have a material adverse effect on the Company's results
of operations. See "Risk Factors--Risk Related to Intangible Assets and
Amortization of Goodwill."
 
    Interest expense was $152,000 during the fiscal year ended September 30,
1997, as compared to none in the prior year, and was attributable to two and one
half months of interest on funds drawn on the Company's revolving credit
agreement for acquisition purposes.
 
    As a consequence of incurring the foregoing expenses, the Company suffered a
net loss of $2,639,000 for the fiscal year ended September 30, 1997 as compared
to net income of $555,000 for the prior fiscal year.
 
FISCAL YEAR ENDED SEPTEMBER 30, 1996 COMPARED WITH FISCAL YEAR ENDED SEPTEMBER
  30, 1995
 
    The Company's operating revenues increased to $24,435,000 in the fiscal year
ended September 30, 1996 from $14,657,000 in the fiscal year ended September 30,
1995, representing an increase of $9,778,000, as a result of internal growth. As
of September 30, 1996 the number of managed care patients enrolled in the
Company's networks totaled approximately 35,000 as compared to approximately
27,000 at the same date in 1995.
 
    The cost of medical services for the fiscal year ended September 30, 1996
was $19,492,000, representing an increase of $8,832,000 from $10,660,000 the
prior fiscal year. During the fiscal year ended September 30, 1996, the increase
in operating revenues was slightly higher than the increase in the cost of
medical services, resulting in a $946,000 increase in gross profit (from
$3,997,000 to $4,943,000). The gross margin for the fiscal year ended September
30, 1996 was 20.2% as compared to 27.3% for the prior fiscal year. The decrease
in gross margin is attributable to higher costs relating to patient services and
treatment (including higher utilization of specialists that the Company had to
provide).
 
    General and administrative expenses for the fiscal year ended September 30,
1996 increased to $4,212,000 from $3,545,000 for the preceding fiscal year,
representing 17% and 24%, respectively, of operating revenues for such years.
 
    Depreciation and amortization was approximately $102,000 for the fiscal year
ended September 30, 1996 as compared to $125,000 in the prior fiscal year.
 
    Investment income was $175,000 for the fiscal year ended September 30, 1996,
as compared to none in the prior year, and was attributed to the ability of the
Company to invest the surplus cash balances generated by the sale of Company's
common stock in a private placement.
 
    During the fiscal year ended September 30, 1996 the Company incurred a
$240,000 loss from the sale of property and equipment to an affiliate.
 
    As a result of an increase in gross margin and reduced general and
administrative expenses as a percentage of operating revenues the Company
experienced an increase in net income to $555,000 for the fiscal year ended
September 30, 1996 as compared to $188,000 in fiscal year September 30, 1995.
 
NINE MONTHS ENDED JUNE 30, 1998 COMPARED WITH NINE MONTHS ENDED JUNE 30, 1997
 
    The Company's operating revenues increased to $40,314,000 in the nine months
ended June 30, 1998 from $19,977,000 in the nine months ended June 30, 1997,
representing an increase of $20,337,000 or
 
                                       37
<PAGE>
101.8%. The majority of this increase resulted from the increase in capitation
revenue during the nine months ended June 30, 1998 to $33,860,000 from
$16,165,000 during the nine months ended June 30, 1997. Approximately 90% of the
increase in the capitation revenues from the nine months ended June 30, 1997
when compared to the nine months ended June 30, 1998 resulted from the increase
in the number of managed care patients served by the Company's affiliated
physician organizations as a result of the Company's acquisition program and
approximately 10% of the increase resulted from internal growth of 9,000
enrollees during periods of open enrollment for HMO plans under contract with
the Company's affiliated physician organizations.
 
    Fee-for-service revenue increased to $2,610,000 during the nine months ended
June 30, 1998 from $762,000 during the nine months ended June 30, 1997. This
increase is largely the result of the Company's acquisition program.
Fee-for-service revenue as a percentage of operating revenues increased to
approximately 6.5% during the nine months ended June 30, 1998 from approximately
3.8% during the nine months ended June 30, 1997.
 
    Incentive payments consist of bonus pool revenue that is paid to affiliated
physician organizations. Bonus pool revenue increased to $2,122,000 during the
nine months ended June 30, 1998 from $1,795,000 during the nine months ended
June 30, 1997. This increase was due to additional bonus pools for which
physician organizations that became affiliated with the Company during fiscal
year 1997 and the first quarter of fiscal year 1998 were eligible.
 
    MSO Revenue increased to $1,467,000 for the nine months ended June 30, 1998
from $924,000 for the nine months ended June 30, 1997. The increase in MSO
Revenue resulted from managing additional unaffiliated physician organizations
when compared to the comparable prior period. For the nine months ended June 30,
1998, $631,000 of the MSO Revenue, and for the nine months ended June 30, 1997,
$668,000 of the MSO Revenue, was derived from management services provided to
Yorba Linda Medical Group. As of July 1, 1998, a portion of such revenues was
terminated. See "Risk Factors--Recent Settlement Agreement with Yorba Linda
Medical Group."
 
    The cost of medical services increased to $26,854,000 during the nine months
ended June 30, 1998 from $16,107,000 during the nine months ended June 30, 1997.
Of such cost, monthly capitation payments to primary care physicians and
specialists increased to $8,656,000 during the nine months ended June 30, 1998
from $5,635,000 during the nine months ended June 30, 1997. This increase was
largely attributable to an increase in the number of physicians receiving
capitation payments as a result of the Company's acquisition program. The
reduction in medical costs as a percentage of total operating revenues derived
from medical services from 86.0% for the nine months ended June 30, 1997 as
compared to 69.6% for the nine months ended June 30, 1998 results from the
acquirees operating at significantly lower medical costs and the Company
implementing new contracts with specialists and ancillary health care providers.
The acquired physician organizations have lower medical costs because they have
more control over the utilization of medical services as a result of employing
primary care physicians rather than paying monthly capitation payments to
independent primary care physicians.
 
    During the nine months ended June 30, 1998, operating revenues rose at a
faster rate than the cost of medical services, resulting in an $9,591,000
increase in gross margin (from $3,869,000 during the nine months ended June 30,
1997 to $13,460,000 during the nine months ended June 30, 1998). The gross
margin was 33.4% of total operating revenues during the nine month period ended
June 30, 1998, as compared to 19.4% for the nine month period ended June 30,
1997. The increase in gross margin is a result of the lower medical cost per
enrollee at the acquired physician organizations and the implementation of new
contracts with specialists and ancillary health care providers.
 
                                       38
<PAGE>
    General and administrative expenses for the nine months ended June 30, 1998
rose to $11,299,000 from $4,503,000 for the nine months ended June 30, 1997,
representing 28.0% and 22.5% of gross revenues for such periods. The largest
component of such costs is salaries and benefits. Salaries and benefits
increased to $6,580,000 during the nine months ended June 30, 1998 from
$2,513,000 during the nine months ended June 30, 1997, an increase of more than
162%. This increase resulted from the increase in the number of management and
other personnel hired in preparation for implementation of the Company's growth
strategy and cost containment programs and the increase in personnel
incorporated from the Company's acquisition program.
 
    Physician office expenses increased to $1,097,000 during the nine months
ended June 30, 1998 from $535,000 during the nine months ended June 30, 1997.
This increase is primarily the result of additional offices for the medical
groups acquired pursuant to the Company's acquisition program. Other operating
expenses increased as a result of the implementation of the Company's growth
strategy to $3,622,000 during the nine months ended June 30, 1998 from
$1,455,000 during the nine months ended June 30, 1997, an increase of 149%.
 
    Depreciation and amortization rose to $786,000 for the nine months ended
June 30, 1998 as compared to $114,000 for the nine months ended June 30, 1997,
an increase of 589%.
 
    Interest expense was $1,028,000 during the nine months ended June 30, 1998,
as compared to none in the prior year. Interest expense during the nine months
ended June 30, 1998 was attributable to nine months of interest on funds drawn
on the Company's credit facility for acquisition purposes, including interest
due on promissory notes made by Prospect Medical Group and the Company to the
sellers of Sierra Medical Group and its related physician practice management
company.
 
    As a consequence of the foregoing, the Company earned a net income of
$376,000 for the nine months ended June 30, 1998 as compared to a net loss of
$2,944,000 for the nine months ended June 30, 1997.
 
PRO FORMA NINE MONTHS ENDED JUNE 30, 1998 COMPARED WITH HISTORICAL NINE MONTHS
  ENDED JUNE 30, 1998
 
    The pro forma consolidated statement of operations gives effect to the
acquisition of assets of Antelope Valley Medical Group, the Yorba Linda
Settlement Agreement in which common stock shares were returned to the Company
and the utilization of proceeds of this Offering to repay debt. During June
1998, Sierra Medical Group acquired certain assets of Antelope Valley Medical
Group and the Company acquired certain assets of its related management company.
None of the personnel or facilities of Antelope Valley Medical Group or its
related management company were acquired by Sierra Medical Group or the Company.
The Company believes that it will be able to integrate the acquired assets into
the existing operations of its affiliated physician organizations, thereby
reducing the costs associated with the operations of the assets acquired from
Antelope Valley Medical Group in future periods. The pro forma statement of
operations data has not been adjusted to reflect any reduction in the historical
operating costs of Antelope Valley Medical Group.
 
    The pro forma financial information for the period also gives effect to the
Yorba Linda Settlement Agreement. Certain physicians employed by Yorba Linda
Medical Group who have provided physician services to enrollees of Prospect
Medical Group sought release from the exclusivity and other noncompetition
provisions in their agreements with Prospect Medical Group. Effective July 1,
1998, the Company and Prospect Medical Group entered into the Yorba Linda
Settlement Agreement pursuant to which these physicians who were also
stockholders of the Company have returned to the Company an aggregate of
1,126,323 shares of the Company's Common Stock in exchange for the release from
the exclusivity and other noncompetition provisions in their agreements with
Prospect Medical Group.
 
                                       39
<PAGE>
    The Company's pro forma operating revenues decreased by $978,000 as compared
to the historical operating revenues as a result of including the historical
unaudited revenues of Antelope Valley Medical Group and the reduction in
revenues related to the Yorba Linda Settlement Agreement as if they had been
effected at the beginning of the period. These two events resulted in a net
enrollee decrease of approximately 1,000. The increase in the cost of medical
services of $552,000 can be attributed to the higher historical medical cost per
enrollee of Antelope Valley Medical Group as compared to Yorba Linda Medical
Group. The decrease in general and administrative costs results from cost
savings derived from services no longer provided to Yorba Linda Medical Group
physicians, including a reduction in rent expense. In addition, prior to
acquisition, the former management of Antelope Valley Medical Group had
determined that it could not operate Antelope Valley Medical Group profitably,
and therefore a non-recurring expense totaling $312,000 was recorded by such
management in the eight-month period ended May 31, 1998 in addition to a charge
of $2,856,000 recorded prior to September 30, 1997. Lastly, the pro forma
consolidated statements of operations have also been adjusted to give effect to
the utilization of proceeds of the Offering to pay down debt and thereby reduce
interest expense.
 
LIQUIDITY AND CAPITAL RESOURCES
 
    GENERAL.  The Company requires capital primarily to facilitate its
acquisition strategy and to develop the infrastructure necessary to effectively
manage its affiliated physician organizations. Prior to or concurrent with
establishment of an affiliation relationship with a physician organization,
Prospect Medical Holdings may advance funds to one of its wholly-owned
subsidiaries to acquire the non-medical assets used to operate and manage the
physician organization. Prospect Medical Holdings may also advance funds to an
affiliated physician organization to acquire the medical assets or, in some
cases, the stock of another physician organization.
 
    Generally, contractual payments for capitation tend to be received by the
Company's affiliated physician organizations from the HMOs before the dates when
the Company's capitation and claim payments to its providers are due, improving
cash flow. However, the portion of the Company's revenues that is derived from
its share of HMO bonus pools may be settled quarterly, semi-annually or
annually, well after the revenue has been accrued. Generally, bonus pools are
settled after the end of the contract year. Historically, amounts payable to the
Company that are derived from bonus pools are generally paid in the third
quarter of each calendar year. See "Risk Factors--Fluctuations in Quarterly
Results" for further discussion.
 
    The Company's primary sources of cash since 1996 have been funds provided by
borrowing under the Company's credit facility, by the issuance of equity
securities and by operating activities. Upon consummation of the 1996 Merger in
the fiscal year ended September 30, 1996 the Company raised a net of $2,359,000
through a sale of the Company's common stock in a private transaction. During
fiscal year 1997 the Company began to implement its growth strategy through a
series of acquisitions and affiliations for cash, debt and equity securities.
Through June 30, 1998, the Company paid or committed to pay consideration in an
aggregate amount of approximately $15,950,000 in connection with its
acquisitions plus the issuance of approximately 800,000 shares of common stock
and options to purchase 35,000 shares of common stock of the Company.
 
    In July 1997, the Company (through Prospect Medical Group) acquired all of
the stock of Santa Ana/ Tustin Physicians Group for $5,000,000. In September
1997, the Company acquired all of the stock of Sierra Medical Management and
(through Prospect Medical Group) acquired all of the stock of Sierra Medical
Group for an aggregate purchase price of $6,500,000 in cash, plus $2,500,000
payable pursuant to notes issued by Prospect Medical Group to the sellers,
600,000 shares of the Company's common stock and options to purchase 35,000
shares of common stock of the Company. Such notes bear interest at the rate of
7% per annum, require interest to be paid monthly with $125,000 principal
payable quarterly plus annual principal payments of $250,000 until March 1999
when the unpaid principal balance then outstanding, and all accrued but unpaid
interest, is due and payable in full. The notes to the former shareholders of
Sierra
 
                                       40
<PAGE>
Medical Group provide that Prospect Medical Group will prepay the principal of
such notes in full from the proceeds of this Offering; the interest on such
notes will be paid from internally generated funds. See "Use of Proceeds."
 
    ACQUISITIONS DURING THE CURRENT FISCAL YEAR.  In October 1997 the Company
(through Pegasus Medical Group) acquired certain assets of Western Medical Group
for $700,000. The Company (through Prospect Medical Group) also acquired certain
assets of two medical practices for a total consideration of approximately
$250,000 plus the issuance of up to approximately 10,000 shares of Common Stock
of the Company. As of June 1998 the Company and Sierra Medical Group acquired
certain assets of the Antelope Valley Medical Group and a related entity for
consideration consisting of $500,000 in cash, $500,000 in promissory notes and
200,000 shares of the Company's common stock.
 
    WORKING CAPITAL.  The Company had negative working capital of $2,569,000 and
$2,003,000 at June 30, 1998 and September 30, 1997, respectively. The negative
working capital at September 30, 1997 resulted primarily from current
liabilities incurred in connection with acquisitions and the use of cash in
operations. At June 30, 1998, the negative working capital resulted primarily
from current liabilities incurred in connection with acquisitions. At June 30,
1998, the Company had cash and cash equivalents of $1,765,000 and a working
capital ratio (currents assets to current liabilities) of .73 compared to cash
and cash equivalents of $2,822,000 and a working capital ratio of .77 at
September 30, 1997 and cash and cash equivalents of $693,000 and a working
capital ratio of .78 at June 30, 1997. The increase in cash and cash equivalents
of approximately $2,129,000 from June 30, 1997 to September 30, 1997 resulted
primarily from the receipt of risk pool moneys, cash received from the
acquisition of Santa Ana/Tustin Physicians Group and an increase in capitation
revenues received as a result of the Santa Ana/Tustin Physician Group
acquisition. The decrease in cash from $2,822,000 at September 30, 1997 to
$1,765,000 at June 30, 1998 resulted from the utilization of cash to repay a
portion of the outstanding balance under the Company's credit facility resulted
primarily from the use of the Company's credit line and the Company's income. At
September 30, 1997, the Company had cash and cash equivalents of $2,822,000 and
a working capital ratio of .77 compared to cash and cash equivalents of
$5,333,000 and a working capital ratio of 1.81 at September 30, 1996 and cash
and cash equivalents of $822,000 and a working capital ratio of 1.51 at
September 30, 1995. The decrease in cash and cash equivalents of approximately
$2,511,000 from September 30, 1996 to September 30, 1997 resulted primarily from
the use of $2,200,000 for the Company's acquisition activities and the operating
losses. The increase in cash and cash equivalents of approximately $4,511,000
from September 30, 1995 to September 30, 1996 resulted primarily from proceeds
from the private placement and from operations. The only significant current
asset of the Company other than cash comprises accounts receivable. Accounts
receivable consists primarily of the Company's interest in risk sharing pools,
accrued management fees due from managed physician practices which are not
consolidated, and fee-for-service amounts due from patients and third party
payors. These receivable balances increased from $1,328,000 at September 30,
1996 to $3,247,000 at September 30, 1997 to $4,865,000 at June 30, 1998,
increases of $1,919,000 and $1,618,000, respectively, primarily due to (a) the
increase of 44,000 enrollees as a result primarily of the Company's acquisition
program, the most significant portion of which arose as a result of the July
1997 acquisition of Santa/Ana Tustin Physicians Group, the September 1997
acquisition of certain assets of Sierra Medical Group and Sierra Medical
Management and the June 1998 acquisition of Antelope Valley Medical Group; and
(b) the increase in shared risk receivables of $1,947,000 related to Prospect
Medical Group's acquisitions and internal growth due to an increase in
enrollment and timing of the receipt of payments under the shared risk programs
with HMOs which are typically made during the second and third quarter of the
calendar year.
 
    The Company's current liabilities consist of (i) accrued medical claims,
which are amounts accrued as payable to specialty care physicians and ancillary
providers, (ii) accounts payable and (iii) the current portion of notes payable
and capital lease obligations. The Company's accrued medical claims include
claims received by the Company, together with amounts accrued as estimated costs
for covered medical benefits incurred by the enrollees in the Company's network
but not yet reported to the Company by
 
                                       41
<PAGE>
providers ("IBNR"). Claims that are not disputed by the Company are typically
paid within 30 days of their receipt. The increase in accrued medical claims
from $2,953,000 at June 30, 1997 to $5,918,000 at September 30, 1997 and to
$6,025,000 at June 30, 1998 resulted primarily from the increased number of
enrollees as a result of the Company's acquisition program. The increase in
accrued medical claims from $1,278,000 at September 30, 1995 to $3,063,000 at
September 30, 1996 resulted from internal growth. The increase in accrued
medical claims from $3,063,000 at September 30, 1996 to $5,918,000 at September
30, 1997 resulted primarily from the increased number of enrollees as a result
of the Company's acquisition program.
 
    CREDIT FACILITY.  In July 1997, the Company obtained a credit facility of
$10,000,000 from the Bank in the form of a revolving credit agreement (the
"Facility"). The full Facility was utilized by the Company in connection with
its acquisitions of Santa Ana/Tustin Physicians Group, Sierra Medical Group and
Sierra Medical Management. In February 1998, the Company obtained an increase in
the Facility to $12,500,000. The Facility matures on July 3, 1999, bears
interest at a variable rate based on prime plus applicable margin and is secured
by a first lien on substantially all of the assets of the Company and its
subsidiaries. The Facility is also subject to both affirmative and negative
covenants, including financial covenants. The financial covenants include
maintaining certain financial ratios, such as a current ratio, leverage ratio
and coverage ratio, as well as satisfying a net worth test. As of September 30,
1997, the Company did not meet certain financial ratios. The Bank has waived
compliance with these ratios as of September 30, 1997, and December 31, 1997,
made the waivers effective retroactive to September 1, 1997, and has revised the
ratios for periods thereafter. As of March 31, 1998 and June 30, 1998, the
Company did not meet certain financial ratios and negative covenants. The Bank
has waived compliance with these ratios and negative covenants at those dates.
In connection with the conferral of the Facility and the increase in the amount
available under the Facility, the Company granted seven year warrants to the
Bank for the purchase of 192,725 shares of common stock at $5.00 per share. The
Company intends to renegotiate the terms of or replace the Facility upon
expiration.
 
    As described above, the Company has primarily funded its acquisition program
with draws on its Facility. The assets acquired by the Company and its
affiliated physician organizations have largely been intangible assets. The
result of acquiring such intangible assets with draws on the Facility is
reflected in the significant negative net tangible book value of the Company.
See "Dilution."
 
    EQUIPMENT LOAN.  The Company entered into a loan agreement in September 1997
to finance a portion of the cost of a management information system. The loan
agreement had an original principal balance of approximately $600,000 with an
interest rate of 10.25% per annum and a term of seven years.
 
    ADDITIONAL FINANCING.  As the Company continues to aggressively pursue its
business strategy, additional financing specifically in connection with the
Company's acquisitions will be required. Establishing a health plan with a
limited license under California law and the formation and development of a
Medicare Health Plan will also require additional financing. In addition, the
operation and expansion of affiliated physician organizations will require
ongoing capital expenditures. The Company anticipates repaying the outstanding
balance on the Facility with proceeds of this Offering. The Company anticipates
applying approximately $500,000 of proceeds of this Offering to pay a portion of
the cost to establish a limited license Knox-Keene health plan and a Medicare
Health Plan. The Company anticipates using a draw on its Facility to pay for any
additional costs to establish such plans which the Company currently estimates
will total approximately $2,500,000. The Company anticipates financing future
acquisitions and potential business expansion with a combination of the proceeds
of this Offering, the Facility, and cash flows from operations. Subsequent to
this Offering, the Company believes that a renewal or replacement of the
Facility, including any additional amounts thereunder and cash flow from
operations will be sufficient to meet the Company's currently anticipated
acquisition, health plan establishment, Medicare Health Plan formation and
development, expansion and working capital needs through September 30, 1999. In
addition, in order to meet its long-term liquidity needs, the Company may incur,
from time to time,
 
                                       42
<PAGE>
additional short and long term bank indebtedness and may issue additional equity
and debt securities, the availability and terms of which will depend upon market
and other conditions. Pursuant to the Company's agreements with the
Representative, the Company's ability to issue any securities is restricted for
a period commencing in March 1998 and ending twelve months following the
Effective Date, except for certain specified purposes, which purposes include
acquisitions. See "Risk Factors--Shares Eligible for Future Sale" herein for
further discussion. The Company's ability to issue any convertible debt or
equity securities in a public or private sale may also be restricted under
certain circumstances pursuant to contractual restrictions in the Company's
agreements with its commercial lender. There can be no assurance that such
additional financing will be available upon terms acceptable to the Company, if
at all. The failure to raise the funds necessary to finance its future cash
requirements could adversely affect the Company's ability to pursue its strategy
and could adversely affect its results of operations for future periods.
 
    The Company may require additional financing to the extent the Company
identifies new acquisition candidates that meet its criteria for potential
acquisition candidates and is able to enter into acquisition agreements with
such candidates. The Company may issue shares of its Common Stock for all or a
portion of the consideration to be paid for any such acquisition. There can be
no assurances that the Company will be able to identify any such acquisition
candidates, that the Company will be able to enter into any acquisition
agreements on acceptable terms or that the Company will be able to obtain
sufficient financing to consummate any such future acquisitions.
 
    YEAR 2000.  Many existing computer systems and programs process transactions
using two digits rather than four digits for the year of a transaction. Unless
the hardware and/or the software have been or will be modified, a significant
number of those computer systems and programs may process a transaction with a
date of the year 2000 as the year "00", which could cause the system or the
program to fail or create erroneous results before, on or after January 1, 2000
(the "Year 2000 Issue"). The Company has recently explored the effect of the
Year 2000 Issue in connection with its management information systems,
computerized accounting system, computerized telephone system and all of the
Company's personal computers.
 
    The Company has formed a Year 2000 project team that includes members of its
management information systems department, finance department, senior management
and a computer consultant to continue evaluating and analyzing all systems. An
inventory of all systems and programs that could be affected by the Year 2000
date change has been developed and categorized as to importance.
 
    The Company has recently purchased a sophisticated management information
system (including software, licensing, training and support) for approximately
$1,100,000. The management information system is specifically designed for the
managed care segment of the Company's business, which accounts for approximately
89% of the Company's revenue. The vendor of this system is obligated under the
purchase contract to provide and install a Year 2000 module designed to address
the Year 2000 Issue. The Company commenced using the system on September 1,
1998. The Company anticipates that the Year 2000 module will be installed in
February 1999, and will be tested within 90 days thereafter. No assurances can
be given that the Year 2000 module will resolve the Year 2000 Issue. The Company
does not expect any additional costs associated with the installation of its
Year 2000 module.
 
    The Company also uses a computer system which was leased commencing in 1996
for billing and collection of fee-for-service accounts receivable, which
accounts for less than 7.5% of the Company's revenues. This system is not
currently Year 2000 compliant; however, the vendor is scheduled to provide a
software upgrade on October 1, 1998 to enable the computer system to become Year
2000 compliant. The Company anticipates commencing to test the software upgrade
within 30 days after receipt and to complete testing by December 31, 1998 to
confirm that the upgrade will resolve the Year 2000 Issue. No assurance can be
made at this time that the upgrade will resolve the Year 2000 Issue. The vendor
has agreed to provide the upgrade and any technical support required at no cost
to the Company, and has assured the Company that the upgrade has been fully
tested to resolve the Year 2000 Issue. In the event
 
                                       43
<PAGE>
the software upgrade will not resolve the Year 2000 Issue, the Company intends
to terminate the lease for the computer system and the Company anticipates that
it will purchase another computer system which is Year 2000 compliant at a cost
of approximately $100,000 to perform these services. The Company anticipates
that any such cost, if incurred, would be paid from cash flow generated by
operations.
 
    The Company's financial and general ledger systems use a licensed software
program. The licensor has provided a software upgrade to address the Year 2000
Issue at a negligible cost. The Company anticipates that the upgrade will be
tested by approximately October 15, 1998. Although no assurance can be given
that the software upgrade will make the financial and general ledger systems
Year 2000 compliant, accounting software has recently been priced by
representatives of the Company who found that new accounting software for the
Company, which is Year 2000 compliant, currently costs under $5,000. The Company
anticipates that any such cost, if incurred, would be paid from cash flow
generated by operations.
 
    In connection with the anticipated relocation of the administrative offices
of Prospect Medical Systems to its new facilities in Santa Ana, California
(approximately November 1, 1998), management will be entering into a contract
for a new state-of-the-art telephone interconnect system. The software in
connection with the operation and management of the telephone system is operated
through Microsoft Windows NT technology, and the Year 2000 module included with
the telephone interconnect software has already been tested by the manufacturer
who reports that the software is Year 2000 compliant. The telephone interconnect
system will be leased directly from the manufacturer and the lease will provide
for a full service guarantee for the life of the lease (8 years). The cost of
the telephone interconnect system will be approximately $130,000, plus lease
charges which include full service of the equipment by the manufacturer for the
8 year term. The Company anticipates that any such cost will be paid from cash
flow generated by operations.
 
    The Company utilizes personal computers that are connected to a network for
all of its employee workstations. These personal computers all utilize Microsoft
Windows NT as their operating system. The Company believes that the Windows NT
operating system is Year 2000 compliant. Management replaces personal computers
after five years, and the Company anticipates replacing a portion of its
personal computers in 1999 and 2000. The cost anticipated is approximately
$75,000 per year. This cost is generally paid from cash flow generated by
operations.
 
    The Company also has facilities in other parts of Orange County, California,
Santa Barbara and the Antelope Valley region of Los Angeles County (Palmdale,
California and Lancaster, California). All of these facilities will be connected
to the management information system and the computer system for billing and
collections by October 1, 1998. These facilities also operate with personal
computers, which use the Windows NT operating system. Telephone systems at each
location are currently being analyzed to determine if they meet the Year 2000
Issue, or whether they will require replacement. The cost associated with
replacement of telephone systems at these offices is negligible.
 
    The medical equipment at the medical offices managed by the Company has all
been tested and the Company has verified that this equipment is Year 2000
compliant, based on testing of the medical equipment and its related software.
 
    The Company primarily does business with hospitals and HMOs. The Company has
contacted all of the hospitals and HMOs with which it does business and has
verified that they are in the process of preparing for the Year 2000. The
Company has been provided assurances that the hospitals and HMOs will be Year
2000 compliant by March 1999, although no assurances can be given by the Company
with respect to these other parties.
 
    Any failure of the HMOs and third-party payors to become prepared for the
Year 2000 could result in substantial adverse difficulties for the Company and
its business. The most reasonably likely worst case scenario for the Company is
the failure of the HMOs to become Year 2000 compliant. In the event the HMOs
that contract with the affiliated physician organizations do not become Year
2000 compliant in a
 
                                       44
<PAGE>
timely manner, the impact could severely and adversely affect the Company's
results of operations and financial condition. Additionally, all information
between the Company and its HMOs would have to be prepared and processed
manually, at substantial cost to the Company.
 
    In the case of third-party payors (Medicare, Medicaid, and indemnity
insurance companies) not becoming Year 2000 compliant in a timely manner, there
would be some impact on the Company's revenues and additional cost to manually
prepare and process claims. However, this segment of the Company's business
accounts for less than 7.5% of its revenues, and is not a primary source of the
Company's business.
 
    In the case of the Company's hospital relationships, in the event the
hospitals are not Year 2000 compliant, all claims, authorizations, and
in-patient hospital days would have to be processed manually, which could delay
patients from obtaining needed medical care promptly, and potentially expose the
Company to possible liability from the patients. The Company does not
anticipate, however, that a failure of the hospitals to become Year 2000
compliant would materially adversely affect its business, results of operations
or financial condition.
 
    The Company's project team is in the process of developing a contingency
plan which will be completed by March 31,1999, in the event that a) any of
Company's systems or programs fail to be Year 2000 compliant; or b) that any of
the parties with which the Company has its principal business relationships
(hospitals, HMOs or third-party payors as described above) fail to be Year 2000
compliant. See "Risk Factors--Year 2000 Risks."

                            BUSINESS OF THE COMPANY
 
GENERAL
 
    The Company manages and administers physician organizations (i.e., medical
groups and independent practice associations) that have entered into agreements
with HMOs to provide physician and certain ancillary health care services to HMO
members under capitated or prepaid fee arrangements. Management services are
provided by the Company to each affiliated physician organization pursuant to a
long-term management services agreement. Under this long-term management
services agreement, the Company provides the physician organization with certain
management and administrative support services, such as claims administration,
utilization management and quality assurance, case management, data collection
and management information systems and payor and provider contracting. The
Company also provides its affiliated medical groups with leased premises,
furniture, fixtures, equipment and personnel (which the Company does not provide
its affiliated independent practice associations, as such associations are
operated as separate businesses with respect to these items). In order to secure
its rights under the management services agreement, the Company enters into an
assignable option agreement with the physician organization which gives the
Company the right to designate the physician or physicians who will own the
physician organization. See "The Affiliated Physician Organizations--Management
Services", below.
 
    Physician organizations increasingly are responding to the cost-containment
pressures within the managed care industry (see "Managed Care Industry
Overview", below) by affiliating with organizations such as the Company. The
Company's management services are intended to allow affiliated physician
organizations to deliver required medical services in a more cost effective
manner. Management believes that cost savings can be generated without adversely
affecting the quality of care provided by the physician organizations by, for
example, managing the risk for hospital services as well as physician and
ancillary health care services, negotiating favorable HMO and provider
contracts, and generating operating efficiencies. See "Strategy of the Company",
below. The Company's fee arrangements with affiliated physician organizations
are structured so as to allow the Company to benefit from the savings so
obtained. See "The Affiliated Physician Organizations--Management Services",
below.
 
    The Company's management and administrative functions are performed by its
wholly-owned subsidiaries, Prospect Medical Systems and Sierra Medical
Management. Prospect Medical Systems conducts its operations in Orange, Los
Angeles, Ventura and Santa Barbara Counties of Southern California and currently
manages Prospect Medical Group and Santa Ana/Tustin Physicians Group. Sierra
Medical Management conducts its operations in the Antelope Valley region of Los
Angeles County and currently manages Sierra Medical Group (including the assets
acquired from Antelope Valley Medical Group) and Pegasus Medical Group. Under
California law, the Company and its subsidiaries are prohibited both from
engaging in the corporate practice of medicine and from contracting directly
with HMOs. Therefore, the physician organizations with which the Company
affiliates (see "The Affiliated Physician Organizations," below) enter into all
HMO contracts and hire and contract with physicians and ancillary health care
service providers in order to provide the medical services which such physician
organizations are obligated to provide under their HMO contracts. See "The
Affiliated Physician Organizations--Provider Agreements", below. The
non-physician components of hospitalization are provided to the enrollees by
hospitals that contract with and are paid by the HMOs. Currently, the Company's
affiliated physician organizations have contracts with approximately 17 HMOs,
from which the Company's revenue is primarily derived.
 
    The Company's primary growth strategy includes the acquisition by its
affiliated physician organizations of other medical groups and independent
practice associations. See "Strategy of the Company", below. Since July 31,
1996, when current management assumed control of the Company, the number of
enrollees served by the Company's affiliated physician organizations has
increased from approximately 6,800 to approximately 97,000 as of June 30, 1998,
and over 100,000 as of July 31, 1998, principally through four strategic
acquisitions. As of June 30, 1998, the affiliated physician organizations
provided services
 
                                       46
<PAGE>
through approximately 350 primary care physicians and 1,390 specialists in the
Company's provider network. See "History of the Company", below.
 
    The Company believes that one of its strengths is its experienced
management, which has provided a foundation to develop and manage the Company's
current operations and future growth. See "Management of the Company."
Management believes that the Company is viewed more favorably by potential
acquisition candidates because its Chief Executive Officer and President have
been practicing physicians. Its Chief Executive Officer, Jacob Y. Terner, M.D.,
previously served as Chairman of the Board and Chief Executive Officer of
Century MediCorp, a publicly-traded corporation operating through three wholly-
owned HMO subsidiaries, hospitals and an affiliated independent practice
association until its October 1992 merger with a major publicly-traded HMO. The
Company believes that physician management fosters better relationships with
providers, thereby enhancing existing operations as well as appealing to
potential acquisition candidates. In keeping with the Company's strategy of
"corporate clout/local control," the Company typically retains senior management
of the entities which it acquires.
 
MANAGED CARE INDUSTRY OVERVIEW
 
    Medical services have traditionally been provided on a fee-for-service basis
with insurance companies assuming responsibility for paying all or a portion of
such fees. Over the past decade, however, the costs of medical services have
generally risen at a higher rate than the consumer price index. As a result,
insurers, employers, state and federal governments and other health insurance
payors have been seeking to reduce or control the sustained increases in health
care costs. The response to these cost increases has been a shift away from the
traditional fee-for-service method of paying for health care, and the resultant
emergence of HMOs and other managed health care organizations which rely on the
concept that prepayment based on prior negotiation is an effective way of
controlling health care costs.
 
    HMOs offer a comprehensive health care benefits package in exchange for a
fixed, prepaid monthly fee or premium per enrollee that does not vary through
the contract period regardless of the quantity or quality of medical services
used. HMOs enroll members by entering into contracts with employer groups or
directly with individuals to provide a broad range of health care services for a
prepaid charge, with minimal or no deductibles or co-payments required of the
members. HMOs, in turn, contract directly with physicians, physician groups,
hospitals and other health care providers to administer medical care to HMO
members. These contracts provide for payment to the provider on either a
discounted fee-for-service or per diem basis, or through a fixed monthly payment
(also referred to as a capitation payment) based on the number of members
covered, regardless of the actual need for and utilization of covered services.
Under these contracts the provider assumes the financial risk that all necessary
health care services can be provided at a cost less than the amount paid to the
provider by the HMO. These contracts may also include incentive arrangements
from HMOs for efficient utilization of hospital services or specialist services.
Such arrangements include incentive payments to be made by the HMO or amounts
withheld by the HMO from the contracted payment amounts. These payments or
amounts are distributed to the physician organization and other participants
(e.g., the hospital) following a reconciliation of budgeted expenses against
actual expenses. To the extent actual expenses exceed budgeted expenses, the
physician organization and other participants may be required to contribute
additional amounts to pay such expenses.
 
    In states such as California, a provider can only accept risk from an HMO
for those services which the provider is authorized to perform within the scope
of its licensure. Thus, a physician or physician group cannot accept risk for
the provision of hospital services, and a hospital cannot accept risk for
physician or certain ancillary health care services. A provider in California,
however, may obtain a license under Knox-Keene, the same California law that
governs HMOs, and thereby accept risk for both physician and certain ancillary
health care and hospital services.
 
    Practitioners in small to mid-sized physician organizations find themselves
at a competitive disadvantage in the managed care environment. They generally do
not have the market presence, expertise, or
 
                                       47
<PAGE>
sophisticated cost accounting and quality management systems required for
capitated risk-sharing arrangements. In addition, they often lack the capital
required to purchase new medical equipment and information systems to enhance
the efficiency and quality of their practices. Administrative burdens have been
exacerbated by the proliferation of HMOs, which require physicians to comply
with multiple formats for claims processing, credentialing and other
administrative reporting requirements. As a result, physicians' operating
expenses and the number of hours devoted to non-medical activities have
increased.
 
    Physician organizations increasingly are responding to the cost-containment
pressures within the managed care industry by affiliating with organizations,
such as the Company, to control economic risk and perform the non-medical
management and administrative tasks that arise from the practice of medicine in
a managed care setting. These organizations provide management and other
administrative services to physician organizations, including personnel,
utilization management and quality assurance, case management and data
collection and management information systems. These organizations also help
physician organizations by negotiating capitation rates and incentive payment
arrangements with HMOs and other payors. These organizations may manage a
portion of the economic risks involved in providing health care or assist
physician organizations that accept full financial risk for all physician and
ancillary health care services to be provided under HMO agreements.
 
HISTORY OF THE COMPANY
 
    The Company was formed on May 12, 1993 as a Delaware corporation. Following
its formation, the Company (then named Med-Search, Inc.) provided managed care
and medical practice management services to a California professional
corporation doing business as Interstate Care Providers ("ICP"). As of July 31,
1996, ICP had managed care contracts with four HMOs, through which it managed
approximately 6,800 capitated lives, primarily in Ventura County, California.
 
    On July 31, 1996, control of the Company was transferred to certain
investors (including Jacob Y. Terner, M.D.) in a private transaction and to
former physician stockholders of Prospect Medical Systems (including Gregg
DeNicola, M.D.). A new Board of Directors was elected and the new Board of
Directors appointed Dr. Terner as the Chairman of the Board and Chief Executive
Officer and Dr. DeNicola as the President. Concurrently with the change of
control, the 1996 Merger was completed. Upon consummation of the 1996 Merger,
the Company's name was changed to Prospect Medical Holdings, Inc. The Company
raised $2,500,000 in the private transaction to finance short-term working
capital needs immediately after the 1996 Merger.
 
    Following the 1996 Merger, management began to implement the Company's
growth strategy through a series of acquisitions and affiliations. On July 14,
1997, Prospect Medical Group acquired all of the outstanding shares of stock of
Santa Ana/Tustin Physicians Group for the cash consideration of $5,000,000. The
founder and former sole shareholder of Santa Ana/Tustin Physicians Group
continues to serve as its president pursuant to the terms of a two-year
employment agreement. Concurrently, Santa Ana/Tustin Physicians Group signed a
long-term management services agreement with Prospect Medical Systems.
 
    On September 25, 1997, Prospect Medical Group acquired all of the
outstanding shares of stock of Sierra Medical Group. Sierra Medical Management,
Inc. ("Old Sierra") concurrently merged into a wholly-owned subsidiary of
Prospect Medical Holdings, Inc., which subsidiary signed an amended and restated
management services agreement with Sierra Medical Group. The aggregate
consideration paid was $6,500,000 plus promissory notes in the aggregate
principal amount of $2,500,000 and the issuance of 600,000 shares of the
Company's common stock and options to purchase 35,000 shares of the Company's
common stock. The founders and former shareholders of Sierra Medical Group,
Sinnadurai E. Moorthy, M.D. and Karunyan Arulanantham, M.D., executed three-year
consulting and employment agreements, respectively, with Sierra Medical Group
subsequent to the acquisition. Jayaratnam Jayakumar, the administrator of Sierra
Medical Group, executed a three-year employment agreement with Sierra Medical

Management and has primary responsibility for the day-to-day management of
Sierra Medical Management.
 
    On October 31, 1997, Pegasus Medical Group, a wholly-owned subsidiary of
Prospect Medical Group, acquired certain assets of Western Medical Group located
in the same service area as Sierra Medical Group for the aggregate cash
consideration of $700,000. Concurrently, Pegasus Medical Group signed a
long-term management services agreement with Sierra Medical Management.
 
    During June 1998, Sierra Medical Group acquired certain assets of Antelope
Valley Medical Group and the Company acquired certain assets of its related
management company for the aggregate consideration of $500,000 in cash and
$500,000 payable pursuant to promissory notes issued by the Company plus the
issuance of 200,000 shares of the Common Stock of the Company. Antelope Valley
Medical Group is located in the same service area as Sierra Medical Group.
 
    As of July 1, 1998, the Company and Prospect Medical Group entered into the
Yorba Linda Settlement Agreement. Pursuant to the Yorba Linda Settlement
Agreement the physicians who were released from their exclusivity and
noncompetition agreements with Prospect Medical Group returned to the Company an
aggregate of 1,126,323 shares of the Company's Common Stock that was previously
issued to them and repaid approximately $60,000. See "Risk Factors--Recent
Settlement Agreement with Yorba Linda Medical Group" and "Unaudited Pro Forma
Financial Information" for a description of the anticipated effect of the Yorba
Linda Settlement Agreement on the results of operations, financial condition and
cash flows of the Company.
 
STRATEGY OF THE COMPANY
 
    The Company believes that the managed care industry operates most
effectively on a regional basis, and is affected most by provider competition,
physician referral patterns, custom and practice and local hospital
relationships. Management believes that developing a significant local market
presence permits economies of scale and greater efficiencies through
centralization of operations. Management believes there is more economic
opportunity in developed rather than in undeveloped managed care markets because
(i) physicians and hospitals in developed markets have established practice and
referral patterns that are consistent with providing services within a managed
care framework and (ii) there is generally a higher concentration of physicians
and hospitals in a developed market, creating a more competitive environment
with greater opportunities for the Company and its affiliated physician
organizations to negotiate more favorable provider contracts. The Company has
selected Southern California as the initial primary service area for its
operations because management believes that Southern California is a highly-
developed managed care market.
 
    Management of the Company intends to focus on the following factors in
seeking to achieve its business strategy. These factors relate primarily to the
expansion of the Company's business through acquisitions and establishment of a
licensed health plan as well as increasing operational efficiencies.
 
    ACQUISITIONS.  The Company views the acquisition and incorporation of
additional physician organizations with a concentration of managed care patients
into its provider network as the most direct route to size and stability. The
Company is focusing on physician organizations with approximately 10,000 or more
capitated HMO enrollees as possible acquisition candidates. The criteria which
the Company has developed to assess potential acquisitions include (i) either a
history of profitable operation or a compelling synergy with opportunities for
economies of scale through combining operations; (ii) either geographic
proximity to the Company's current operations or a material share of the
potential acquisition candidate's own local marketplace; (iii) a favorable
hospital relationship; and/or (iv) willingness of the acquisition candidate's
management to continue managing the acquired entity following its acquisition.
The Company also intends to increase its operations through the acquisition of
additional management companies in order to create a regional network to provide
management services to additional physician organizations.
 
                                       49
<PAGE>
However, there can be no assurance that any definitive agreements will be
executed or that any such acquisitions or affiliations will be consummated.
 
    The Company believes that it will be able to continue to attract physician
organizations by (i) offering the affiliated physicians of the incorporated
entities the benefits of payor contracts negotiated by the Company on behalf of
one of the Company's affiliated physician organizations, together with the
opportunity to build a larger patient base; (ii) allowing physicians who are
otherwise reluctant to associate with management companies (a) substantial
control over the provision of medical services and operations in their
geographic areas according to the needs of their patients, thus providing
flexibility in a continually changing market, and (b) an opportunity to play an
ongoing role in the management of their practices; and (iii) relieving
physicians from the administrative burden imposed by compliance with a variety
of HMO contracts. At the same time, the Company can offer to these physicians
the benefits of improved information resulting from its centralized management
information systems, accounting and other financial services.
 
    INTERNAL GROWTH.  Management of the Company also intends to grow through the
addition of new enrollees to its service network. The Company provides marketing
services to its affiliated physician organizations to promote such growth. With
respect to Prospect Medical Group, the Company seeks to increase its enrollment
through the development of relationships with sales representatives and
marketing directors of HMOs and marketing directors and administrators of
hospitals. Representatives of Prospect Medical Group attend health fairs and
community and other events directed at commercial and Medicare enrollees and
seek to attend these fairs and events as the sole physician organization
whenever possible. The Company has also established a speakers bureau to make
the physicians of Prospect Medical Group available to speak at public events. In
addition, the Company has set up a Web page for Prospect Medical Group and is in
the process of expanding its Web page. The Company intends to develop similar
marketing programs for Sierra Medical Group, Santa Ana/Tustin Physicians Group
and Pegasus Medical Group.
 
    EXPANDING SCOPE OF LICENSURE; ESTABLISHING FULL-RISK HEALTH PLANS.  Under
applicable California law, the Company's affiliated physician organizations can
accept risk under their contracts with HMOs only with respect to services which
are within the scope of their licensure, such as physician and ancillary health
care services. The affiliated physician organizations cannot accept risk from an
HMO with respect to services which are currently outside of the scope of their
licensure, such as hospital services. The HMOs which now contract with the
Company's affiliated physician organizations for physician services must
contract directly with hospitals for hospital services, which deprives the
Company and its affiliated physician organizations of control over the way in
which such services are provided.
 
    As part of its future strategy, the Company or an affiliated physician
organization may seek to obtain the state and federal regulatory approvals
necessary to establish a licensed health plan in order to manage both hospital
and physician and ancillary health care services. As a health plan, the Company
or its affiliate would receive a fixed payment in return for full responsibility
to provide and pay for all hospital, physician and ancillary health care
services. By managing full risk the Company believes that it can achieve greater
control over patient care through its utilization management and quality
assurance protocols.
 
    The Company intends to seek to allocate the risk for hospital services to
the hospitals within its inpatient provider network by entering into fixed fee
or capitated payment arrangements. All other services not provided directly by
an affiliated physician organization would be subcontracted out to other
providers; the Company intends to seek to use fixed fee schedules that include
per diems, case rates and other favorable arrangements. The profitability of any
licensed health plan established by the Company will be dependent upon the
ability of the Company to negotiate favorable arrangements with hospitals and
other subcontractors. There can be no assurance, however, that any hospital or
other subcontractor will agree to provide such services on a fixed fee or
capitated payment basis or upon terms otherwise favorable to the Company.
 
                                       50
<PAGE>
    In order to be able to provide hospital, physician and ancillary health care
services on a full-risk basis under California law, the Company expects to seek
a form of Knox-Keene HMO licensure known as a "limited license" or a "license
with waivers". The holder of a limited license under Knox-Keene may provide
services on a full-risk basis to commercial, Medicare and/or Medicaid members of
other (fully-licensed) plans and is precluded from contracting directly with
subscribers. A limited Knox-Keene health care service plan license, unlike a
full Knox-Keene health care service plan license, would not permit the Company
to market directly to employer groups to promote its health plan. With such a
license, the Company must enter into contracts with fully-licensed health plans
and can provide services only to the members of the plans with which it
contracts. The fully-licensed HMO performs all advertising and marketing
functions, collects all premiums from the purchasers of plan services and
performs certain administrative services that vary by HMO. The Company expects
that such a limited license would be easier to obtain than a full license,
although no assurances can be given, and would forestall direct competition
between the Company and the HMOs with which it contracts. Upon obtaining the
required licensure, the Company believes that it or its affiliate will be able
to obtain full-risk contracts with HMOs, although no assurances can be given.
 
    The Company might alternatively seek a full Knox-Keene license in order to
market directly to, and collect premiums from, Medicare enrollees (but not
commercial enrollees). It is expected that this form of license would permit the
Company to both operate as a Medicare Health Plan and to accept full risk from
other fully-licensed plans as if it held a limited license as described above.
To date, however, no health plan has received such a license, and no assurance
can be given that such a license can be obtained. While such a license may be
harder to obtain, it would enable the Company's health plan to contract directly
with HCFA (the federal governmental agency responsible for administering and
overseeing the Medicare program) to serve Medicare beneficiaries under the
Medicare+Choice program which was established under the Federal Balanced Budget
Act of 1997 (the "Budget Act"). The Medicare+Choice program was formulated to
give Medicare beneficiaries health plan options in addition to the original
Medicare fee-for-service program and already existing Medicare HMOs.
 
    The Company believes that formation and development of a Medicare+Choice
health plan may provide opportunities for future growth. According to an article
in the Winter 1998 edition of the California Health Care Financial Management
journal, enrollment growth in managed care plans by Medicare beneficiaries has
been increasing at an annual rate of approximately 25% nationwide, with HMOs
enrolling approximately 13% of all Medicare beneficiaries nationwide. The same
article indicated that enrollment in managed care plans by Medicare
beneficiaries in the State of California increased 9.8% during the year ending
June 30, 1997, bringing the total enrollment to nearly 1.4 million
beneficiaries, or 35% of the eligible population.
 
    One of the plan categories available to members under the Medicare+Choice
program is the Coordinated Care Plan, which includes HMO plans,
provider-sponsored organization ("PSO") plans, and preferred-provider
organization plans. A PSO is an entity that is established or organized and
operated by a provider or group of affiliated health care providers and must be
majority-owned by affiliated health care providers. The Budget Act defined
"health care provider" as an individual who is engaged in the delivery of health
care services and is required by state law or regulation to be licensed or
certified to deliver such services, or an entity which is engaged in the
delivery of health care services and is licensed or certified to provide such
services, if so required.
 
    A Medicare+Choice Coordinated Care Plan (a "Medicare Health Plan") contracts
directly with HCFA to provide hospital, physician and ancillary health care
services to Medicare beneficiaries. A Medicare Health Plan is allowed to provide
services on behalf of only one payor (HCFA) and only one enrollee population
(Medicare beneficiaries). A Medicare Health Plan performs all advertising and
marketing functions and collects all premiums from enrollees. As a result, the
formation of a Medicare Health Plan could potentially place the Company in
competition for Medicare beneficiaries with the HMOs now contracting with the
Company's affiliated physician organizations. The Company intends to
 
                                       51
<PAGE>
avoid competing with such HMOs by marketing its Medicare Health Plan only in
areas where the Company's affiliated physician organizations do not serve
Medicare beneficiaries. The Company does not intend to operate a Medicare Health
Plan in a manner that would interfere with the established relationships of its
affiliated physician organizations with their contracting HMOs. However, no
assurances can be given as to the response of existing HMOs to any perceived
competition by a new Medicare Health Plan.
 
    A Medicare Health Plan is required to obtain certification from HCFA. The
Company or an affiliated physician organization may apply for licensure as a
Medicare Health Plan to serve Medicare beneficiaries within its service area who
currently are not served by providers within its network. In addition, in
California, Medicare Health Plans which are HMO plans or PSO plans must be
licensed as Knox-Keene health care service plans. To date, however, no PSO has
been licensed under Knox-Keene, and no assurances can be given that such a
license can be obtained.
 
    As described under "Governmental Regulation" below, once the Company or its
affiliate has obtained a license under Knox-Keene, whatever its form, the
Company or its affiliate will be subject to continuing regulation by the DOC and
must continue to meet certain operating requirements. The Company believes that
the management information system that it is currently implementing and the
infrastructure that it has developed will satisfy a substantial portion of the
data reporting and organizational and administrative capacity requirements to
assume full risk as a limited license Knox-Keene plan or additional HCFA
requirements for a Medicare Health Plan, or to assist an affiliated physician
organization to meet such requirements, although management is aware that HCFA
has not yet established specific reporting requirements for Medicare Health
Plans. There can be no assurance, however, that the Company or its affiliate
will be able to obtain the required licenses or certification or to satisfy any
other regulatory requirements. See "Governmental Regulation," below.
 
    Management of the Company anticipates that state licensure for a health plan
under Knox-Keene could occur in six to twelve months and the federal Medicare
certification process would take four to six months following submission of the
application to HCFA. To finance all or a portion of the cost of formation and
development of a licensed health plan, the Company intends to apply, or lend to
its affiliated physician organization, a portion of the proceeds from this
Offering; the Company intends to finance the remainder of such cost from
borrowings under its revolving credit agreement (the "Facility"). No assurance
can be given that the Company or an affiliated physician organization will be
able to obtain a Knox-Keene license or Medicare Health Plan certification or
that sufficient funds will be available to finance the associated costs which
would satisfy regulatory reserve and working capital requirements.
 
    ABILITY TO NEGOTIATE FAVORABLE HMO AND PROVIDER CONTRACTS.  Management
believes that the most significant benefit of increased size of its affiliated
physician organizations may be the ability to negotiate HMO and specialist
contracts on a more favorable basis. The Company believes that as its affiliated
physician organizations provide services to a larger number of members of each
of their contracting HMOs, the Company's bargaining power will increase and, as
a result, the Company may be able to negotiate more favorable contract terms,
including capitation rates. The Company believes that the ability to offer a
larger number of enrollees to specialist physicians may also enable the
affiliated independent practice associations to contract with specialist
physicians at more competitive rates.
 
    STRENGTHEN PROVIDER NETWORK.  Management of the Company also recognizes the
importance of contractual arrangements that strengthen relationships with the
providers. The Company assists its affiliated independent practice associations
in negotiating agreements with contracting physicians and other medical
providers. The Company seeks to include in these agreements provisions under
which (i) a contracting physician agrees to refrain from providing physician
services to members of HMOs except through Company-affiliated physician
organizations (an exclusivity provision), and (ii) a contracting physician is
required to refrain from soliciting or diverting an enrollee of a
Company-affiliated physician organization to enroll with a physician
organization unaffiliated with the Company (a non-solicitation or
 
                                       52
<PAGE>
non-diversion provision). Providers are offered higher capitation rates as an
incentive to become an exclusive provider. The Company believes that as of June
30, 1998 approximately 9 of the physicians within its provider network had
exclusivity provisions in their contracts with an affiliated independent
practice association (see "The Affiliated Physician Organizations," below).
Certain other physicians have non-diversion or non-solicitation provisions in
their contracts with an affiliated independent practice association. The Company
believes the inclusion of these provisions, particularly exclusivity,
non-solicitation and non-diversion provisions, strengthens and differentiates
its provider network. No assurances can be given as to the enforceability of
these provisions.
 
    OPERATING EFFICIENCIES.  The Company believes that consolidating additional
physician organizations that are acquired by the Company's affiliates will
enable the Company to provide improved management services to the affiliated
physician organizations on a more cost-effective basis. To integrate the newly
acquired physician organizations, the Company intends to centralize the
functions of credentialing, claims, finance, utilization management, quality
assurance and management information systems with the assistance of an on-site
person for quality assurance and utilization review. The Company will evaluate
each acquired physician organization on a case-by-case basis in order to
determine which, if any, administrative and management functions are most
efficiently handled locally.
 
    Since August 1996, the Company has taken several significant steps to
develop its management and operations infrastructure and improve its operational
efficiencies. Infrastructure development has included creation of distinct
departments with specific responsibilities for clinical operations, including
quality management and case management; claims and management information
systems operations; contracting; and independent practice association/medical
management and the appointment of experienced managers for each such department.
 
    DECENTRALIZED MANAGEMENT STRUCTURE.  In keeping with the Company's strategy
of "corporate clout/ local control," the Company believes that each physician
organization presents unique management issues and therefore is best served by
decentralized management. As described above, the Company typically retains
senior management of the entities which it acquires or with which it affiliates,
adding additional management personnel as the entity expands. Each physician
organization's physicians continue to maintain full professional control of the
practice of medicine.
 
    ALIGNMENT OF ECONOMIC INTERESTS.  The Company intends to issue shares of its
common stock as all or a portion of the consideration for most future
acquisitions as part of its strategy to give management of entities acquired by
the Company or its affiliates a stake in the Company's future. No assurances can
be given, however, that potential future acquisition candidates or affiliates
will accept shares of the Company's common stock.
 
THE AFFILIATED PHYSICIAN ORGANIZATIONS
 
    The Company provides management and administrative services to the
affiliated physician organizations under long-term management services
agreements that, together with the assignable option agreements, establish an
affiliation relationship. See "Management Services" below for a description of
the management services agreements and "Assignable Option Agreements" below for
a description of the assignable option agreements. The affiliated physician
organizations include medical groups that employ physicians and independent
practice associations that contract with physicians and other medical providers.
As of June 30, 1998, the affiliated physician organizations employed
approximately 28 primary care physicians and 1 specialist and contracted with
approximately 326 primary care physicians and 1,389 specialists.
 
    Currently, the Company provides management and administrative services to
the four affiliated physician organizations described below (the "Physician
Organizations"). Dr. DeNicola is currently the
 
                                       53
<PAGE>
sole shareholder, a director and officer of Prospect Medical Group and Prospect
Medical Group is the sole shareholder of the three remaining Physician
Organizations.
 
    PROSPECT MEDICAL GROUP.  Prospect Medical Group, which includes a medical
group and independent practice association, operates substantially in Orange
County with smaller operations in Ventura, Santa Barbara and Los Angeles
Counties. As of June 30, 1998, Prospect Medical Group provided professional
medical services to approximately 54,000 enrollees through capitated contracts
with 15 HMOs. If the Yorba Linda Settlement Agreement had been entered into on
or before June 30, 1998, the Company estimates that Prospect Medical Group would
have provided medical services to at least 40,600 enrollees as of June 30, 1998.
In addition, Prospect Medical Group provides limited services on a traditional
fee-for-service basis. See "Management of the Company."
 
    SANTA ANA/TUSTIN PHYSICIANS GROUP.  Santa Ana/Tustin Physicians Group is
located in Central Orange County, California. Santa Ana/Tustin Physicians Group
includes a medical group practice composed of primary care physicians located in
Santa Ana, California as well as a physician delivery network consisting of
multiple independent physician practices. As of June 30, 1998, Santa Ana/Tustin
Physicians Group provided professional medical services to approximately 10,400
enrollees through capitated contracts with three HMOs.
 
    SIERRA MEDICAL GROUP.  Sierra Medical Group is located in the Antelope
Valley region of Los Angeles County, California. As of June 30, 1998, Sierra
Medical Group provided professional medical services at three offices, located
in the cities of Palmdale and Lancaster, to approximately 27,000 individuals,
including individuals who previously were enrollees of Antelope Valley Medical
Group, assigned to it under contracts with thirteen HMOs as well as other health
care programs. As of June 30, 1998, Sierra Medical Group received approximately
90% of its revenues from managed care contracts with HMOs. The remaining 10% was
made up from fee-for-service revenues.
 
    PEGASUS MEDICAL GROUP.  Pegasus Medical Group is located in the Antelope
Valley region of Los Angeles County, California. As of June 30, 1998, Pegasus
Medical Group provided professional medical services to approximately 5,600
persons through capitated contracts with four HMOs.
 
    Set forth below is a chart showing each of the HMOs contracting with the
affiliated Physician Organizations, the number of enrollees of the Physician
Organizations served pursuant to each HMO's contracts and the percentage of the
total number of enrollees of the Physician Organizations served pursuant to each
HMO's contracts as of June 30, 1998. The chart below shows the contracts
covering commercial members, Medicare beneficiaries and Medicaid beneficiaries
as separate contracts although the contracts may be held by the same HMO.

    PROVIDER AGREEMENTS
 
    Decisions regarding patient health care are made exclusively by physicians
who are employees of or contract with the Company's affiliated Physician
Organizations and are rendered in connection with guidelines and policies
developed and administered by the medical director of the affiliated medical
group.
 
                                       55
<PAGE>
Each independent practice association enters into the following types of
contracts for the provision of physician and ancillary health care services:
 
    PRIMARY CARE PHYSICIAN AGREEMENT.  This agreement provides that primary care
physicians contracting with an independent practice association are responsible
both for the provision of primary care services to enrollees and for the
referral of enrollees to specialists affiliated with the independent practice
association when appropriate. Primary care physicians receive monthly capitation
or reduced fee-for-service payments for the provision of primary care services
to enrollees. An independent practice association can terminate the primary care
physician agreement immediately upon the occurrence of certain specified events,
including suspension, restriction or revocation of the physician's license to
practice medicine in California, denial, restriction or revocation of medical
staff privileges at any hospital for medical disciplinary reasons, and loss of
professional liability insurance, among others. Either party may terminate the
agreement, with cause, upon 30 days' prior written notice. During the term of
the agreement, neither party may terminate the agreement without cause.
 
    SPECIALIST AGREEMENT.  This agreement provides that specialty care
physicians contracting with an independent practice association receive either
(i) discounted fee-for-service or case rate payments, or (ii) subcapitated
payments for the provision of specialty services to those enrollees referred to
them by the independent practice association's primary care physicians. An
independent practice association can terminate the specialist agreement
immediately upon the occurrence of certain specified events, including
suspension, restriction or revocation of the physician's license to practice
medicine in California, denial, restriction or revocation of medical staff
privileges at any hospital for medical disciplinary reasons, and loss of
professional liability insurance, among others. Generally, either party may
terminate the agreement, with or without cause, upon 90 days' prior written
notice.
 
    ANCILLARY PROVIDER AGREEMENT.  This agreement provides that ancillary
service providers (generally non-physician providers such as physical
therapists, laboratories, etc.) contracting with an independent practice
association receive monthly capitation or discounted fee-for-service payments
for the provision of services to enrollees on an as-needed basis. Generally,
either party can terminate the ancillary provider agreement with or without
cause upon 60-90 days' written notice.
 
    MANAGEMENT SERVICES
 
    Prospect Medical Systems has executed separate long-term management services
agreements with each of Prospect Medical Group and Santa Ana/Tustin Physicians
Group. Sierra Medical Management has executed separate long-term management
services agreements with Sierra Medical Group and Pegasus Medical Group. Each of
the management services agreements contains terms substantially similar to those
summarized below.
 
    Pursuant to the management services agreements, each Physician Organization
has delegated to the Company the non-physician administrative, management and
support functions that are required by the Physician Organization in the
practice of medicine. As compensation for the services provided to each
Physician Organization pursuant to its respective management services agreement,
the Company receives from the revenues of each Physician Organization (i) the
costs of the Company in providing services and satisfying its obligations
thereunder, plus (ii) an additional percentage of the gross revenues, a fixed
fee for marketing and public relations services and a portion of net pre-tax
income of the Physician Organization. Under certain circumstances, the Company
may defer the amount of gross revenues to be paid to the Company.
 
    To secure the payment of all accrued management fees, each Physician
Organization has granted to the Company a security interest in its accounts and
rights to payment. The management services agreements have a thirty (30) year
term and will renew automatically for successive ten-year terms unless either
party elects to terminate them. The management services agreements are
terminable by the
 
                                       56
<PAGE>
unilateral action of the applicable Physician Organization prior to their normal
expiration only for the breach by the Company of its obligations thereunder or
for certain bankruptcy events.
 
    The management services agreements specifically obligate the Company to
provide suitable facilities, fixtures and equipment and non-physician support
personnel (including marketing, clerical, administrative and maintenance
personnel) to each of its affiliated medical groups so that the affiliated
medical groups can adequately provide for all medical services. The Company is
further obligated to provide to the Physician Organizations (including
affiliated independent practice associations) administrative, accounting and
billing services and to assist in all phases of contract administration and
marketing. The Company provides management and administrative functions that do
not constitute the practice of medicine. Under the management services
agreements, the Physician Organizations continue to be solely and exclusively in
control of and responsible for all aspects of the practice of medicine.
 
    The management and administrative services provided under the management
services agreements to the Physician Organizations include the following:
 
    UTILIZATION MANAGEMENT/QUALITY ASSURANCE.  Pursuant to the management
services agreements, the Company assists the Physician Organizations with
development and implementation of a utilization and quality management plan. The
Company further implements systems, programs and procedures necessary for the
Physician Organizations and participating providers to perform utilization and
quality management; organizes procedures for prior authorization of elective,
urgent and emergent out-patient ambulatory surgery and hospital procedures;
assists the Physician Organizations with prospective, concurrent and
retrospective review of medical procedures in accordance with their policies and
HMO health plan requirements; provides data regarding the use of outpatient and
inpatient services by the provider to the Physician Organizations and the use of
noncontracting providers; and assists the medical director and the utilization
review/quality assurance committee of each affiliated medical group in
responding to the HMO plan member grievances based on the instructions of such
medical director.
 
    CASE MANAGEMENT.  Case management is administered by the clinical operations
department and is the clinical and administrative process by which health care
service referrals to specialists and ancillary health care providers are
evaluated, coordinated and implemented on an ongoing basis for both acute
illnesses and enrollees experiencing chronic disability, complex medical cases
or problems requiring long-term care. The latter involve coordination by case
management. The goal of case management is to provide a continuum of quality
care throughout the enrollee's treatment period.
 
    PHYSICIAN CREDENTIALING.  The Company's physician credentialing program
seeks to monitor the physicians within the network. The physician credentialing
program includes the investigation and verification of physicians'
qualifications, credentials and medical staff privileges at the time they are
brought into the network, as well as periodically reviewing competency and
continuing medical education.
 
    MANAGED CARE CONTRACTING.  The Company's services are aimed at evaluating,
negotiating and administering agreements with payors, such as prepaid health
plans; negotiating agreements with specialist and ancillary service providers;
negotiating agreements with out-of-area hospital and ancillary providers; and
coordinating each Physician Organization's network and, with respect to
affiliated medical groups, their office operations.
 
    CLAIMS ADMINISTRATION.  The Company possesses complete medical claims
processing capabilities. These capabilities include determining enrollee
eligibility, identifying appropriate benefits, issuing payments to providers,
processing hospital and outpatient facility charges for the payment of claims
and providing and analyzing encounter data.
 
    FINANCIAL SERVICES.  The Company has exclusive decision-making authority
with respect to the establishment and preparation of annual budgets for the
practice of each affiliated medical group that reflect in reasonable detail
anticipated revenues and expenses. In consultation with each affiliated medical
group the
 
                                       57
<PAGE>
Company establishes bank accounts for the deposit of all sums received by each
affiliated medical group for services provided to members. In addition the
Company may endorse all checks made payable to each affiliated medical group and
deposit checks and funds; prepare financial statements on a monthly basis;
receive and deposit capitation and other payments received by the Physician
Organizations; calculate primary care capitation and specialty, ancillary and
other payable claims based on the records provided by the participating plans
and prepare checks to pay the amounts due; monitor subscribers or enrollees
exceeding stop loss deductibles and communicate with HMOs orally or in writing
to seek reimbursement on behalf of the Physician Organizations; bill other
payors for coordination of benefits and other third party liability payments;
administer capitation and other distributions from HMOs including auditing and
monitoring of HMO incentive payments; negotiate and settle the Physician
Organization's share of such payments; establish and maintain IBNR reserves for
the Physician Organization; and assist the Physician Organizations in
establishing and administering a physician incentive system and a system to
establish and adjust reserves for medical expenses.
 
    BILLING SERVICES.  The Company also provides bookkeeping and accounting
services including the preparation, distribution and recording of all bills and
statements for fee-for-service professional services rendered by the Physician
Organizations as well as all reports and forms required by applicable third
party payors; collection of accounts receivable; and submission, processing and
collection of all claims for payment to, and receipt of payments from,
third-party payors. The Physician Organizations at all times have the ultimate
responsibility for setting all fees for professional services provided on a fee
for service basis to patients of the practice, as well as establishing the terms
of each managed care contract.
 
    PROVIDER RELATIONS.  The Company's services include the preparation,
negotiation and renewal of agreements with each Physician Organization's
providers, and the maintenance of eligibility data in a computerized database.
The Company provides resources to train providers in each Physician
Organization's policies and procedures and assist each Physician Organization in
developing and updating manuals.
 
    MANAGEMENT INFORMATION SYSTEMS.  The Company's management information
systems, which support both practice-oriented and administrative functions,
assist management in maintaining control over the significant growth experienced
during the last two years and are critical to the growth which is anticipated in
the future. The Company's newly acquired management information system is a
sophisticated software system specifically designed for managed care. The
Company commenced using the new system on September 1, 1998. Further, the
Company maintains an on-line database that provides inpatient and outpatient
utilization statistics, and patient encounter reporting. The Company believes
that the availability of timely information on utilization patterns improves
physician productivity and effectiveness. This data also plays an integral role
in the physician utilization control process by enabling the medical directors
and utilization control nurses of the affiliated medical groups to monitor case
management decisions, evaluate patient outcomes and monitor utilization trends.
In addition, the Company's management information systems are capable of
performing various administrative functions including insurance verification,
billing, accounts payable and receivable, outside service referrals and
verification, and all third party claims processing. See "Risk
Factors--Dependence on Information Systems."
 
    PATIENT ELIGIBILITY AND SERVICES.  The Company provides a variety of
services related to patient eligibility, including obtaining eligibility lists
from health plans, assisting with the determination of eligibility of patients
for health care coverage prior to the provision of medical services, maintaining
a computerized eligibility database, distributing eligibility reports and
coordinating health education and wellness programs to enrollees of each
Physician Organization.
 
    PATIENT AND PHYSICIAN RELATIONS.  The Company employs staff to aid patients
and physicians in understanding managed care and the nature and extent of
coverages, assist patients in making informed decisions concerning their medical
care and treatment alternatives, and provide support in resolving financial
questions.
 
                                       58
<PAGE>
    MARKETING AND PUBLIC RELATIONS SERVICES.  The Company will assist each
Physician Organization in the Physician Organization's marketing, public
relations and advertising of the health care services provided by the Physician
Organization. The Company shall provide and be principally responsible for
marketing and advertising services for each Physician Organization. In providing
its marketing services, the Company is acting solely in its capacity as
administrator for the Physician Organization. All such marketing services are to
be conducted in accordance with the laws, rules, regulations and guidelines of
all applicable governmental and quasi-governmental agencies, including but not
limited to the Medical Board of California.
 
    The Company has the right to decline to manage new medical facilities which
a Physician Organization desires to establish or acquire. Consistent with a
Physician Organization's exclusive control of all aspects of patient medicine,
the Physician Organization retains the right to purchase from outside providers
any equipment, facilities or services not provided by the Company. The Company
is obligated to provide all medical and non-medical supplies reasonably
requested by the Physician Organization.
 
    ASSIGNABLE OPTION AGREEMENTS
 
    The assignable option agreements give the Company the assignable right to
designate a successor physician or physicians, which person or persons must be
duly-licensed physicians in the State of California or otherwise permitted by
law to be a shareholder in a professional corporation, to purchase all or any
portion of the stock of an affiliated medical group. The Company may elect to
exercise the option at any time. Dr. DeNicola is currently the sole shareholder,
a director and an officer of Prospect Medical Group (the "nominee shareholder")
and a director and officer of the Company. Prospect Medical Group is the sole
shareholder of Santa/Ana Tustin Physicians Group, Sierra Medical Group and
Pegasus Medical Group. Under the assignable option agreement between Prospect
Medical Systems, Prospect Medical Group and Dr. DeNicola, Prospect Medical
Systems has the right to designate a successor physician or physicians to
purchase for nominal consideration all of the stock of Prospect Medical Group
from Dr. DeNicola. The assignable option agreements effectively give the Company
the ability to protect its rights under the management services agreements.
 
COMPETITION
 
    The managed care industry is highly competitive and is subject to continuing
changes with respect to the manner in which services are provided and how
providers are selected and paid. The Company is subject to significant
competition both in affiliating with physician organizations and in seeking
managed care contracts on behalf of its affiliated Physician Organizations.
Generally, the Company and the Physician Organizations compete with any entity
that contracts with payors for the provision of prepaid health care services,
including but not limited to (i) other companies that provide management
services to health care providers, (ii) hospitals that affiliate with one or
more physician organizations, (iii) HMOs that employ or contract directly with
physicians and (iv) other physician organizations. Additionally, the Physician
Organizations with which the Company is affiliated compete with other medical
practices in the areas in which the Company does business, or is expected to do
business in the future. Pressures to reduce the cost of medical care, through
legal reform of the health care system or through market forces such as the
continued expansion of managed care, could adversely impact the Company's
revenues. Further, increased enrollment in prepaid plans because of health care
reform or for other reasons, increased participation by physicians in group
practices and other factors may attract new entrants into the managed care
industry and result in increased competition for the Company. Certain
competitors, including but not limited to MedPartners, Inc., and Phy Cor, Inc.
and certain of its subsidiaries are significantly larger and better capitalized
than the Company, provide a wider variety of services, have greater experience
in providing health care management services and have longer-established
relationships with buyers of such services than does the Company. There can be
no assurance that the Company will be able to compete effectively with such
competitors, that additional competitors will not enter the market, or that such
 
                                       59
<PAGE>
competition will not make it more difficult to enter into affiliations with
physician organizations on terms beneficial to the Company.
 
    The Company also experiences competition in the recruitment and retention of
qualified physicians and other health care professionals on behalf of its
affiliated Physician Organizations. There can be no assurance that the Company
will be able to recruit or retain a sufficient number of qualified physicians
and other health care professionals to continue to expand its operations. See
"Risk Factors--Highly Competitive Market."
 
GOVERNMENTAL REGULATION
 
    GENERAL HEALTH CARE REGULATIONS.  The health care industry is highly
regulated, and there can be no assurance that the regulatory environment in
which the Company operates will not change significantly in the future.
Generally, regulation of health care companies is increasing and health care
transactions continue to be subject to substantial scrutiny by regulatory
authorities. The Health Insurance Portability and Accountability Act of 1996 is
among the most significant and comprehensive anti-fraud laws to be enacted. Its
provisions create new anti-fraud programs, amend existing anti-fraud statutes to
cover more health care providers and to impose greater penalties for violations,
and create new crimes to combat health care fraud and abuse. In addition to
increased scrutiny of fraud and abuse activity, legislation has been introduced,
and in some cases enacted, which may significantly affect the reimbursement of
health care services under certain health care programs. The recently-enacted
Budget Act will reduce funds available to the Medicare program by $115 billion
over five years. Federal, state and local officials and legislators continue to
propose a variety of reforms to the health care system. Certain reforms could,
if adopted, have a material adverse effect on the Company.
 
    Both federal and state law, including California law, generally specify who
may practice medicine and limit the scope of relationships between medical
practitioners and other parties. Under these laws, the Company is prohibited
from practicing medicine or exercising control over the provision of medical
services. To comply with such laws, the provider network is organized so that
all physician services are offered by the physicians who are employed by or
contract with a Physician Organization. The Company does not employ physicians
to provide medical services, exert control over medical decision-making or
represent to the public that it offers medical services. The Company has entered
into a separate management services agreement with each of the Physician
Organizations which delegates to the Company the performance of administrative,
management and support functions. These agreements specifically reserve
exclusive control and responsibility for all aspects of the practice of medicine
and the delivery of medical services to the Physician Organizations. See "The
Affiliated Physician Organizations--Management Services."
 
    Further, state law imposes licensing requirements on individual physicians
and on facilities operated by physicians. In addition, federal and state laws
regulate HMOs and other managed care organizations with which the Physician
Organizations may have contracts. Some states also require licensing of third-
party administrators and collection agencies. This may affect the Company's
operations in states in which the Company may seek to do business in the future.
In connection with its existing operations and its expansion into new markets,
the Company believes it is in compliance with all such laws and regulations and
current interpretations thereof, but there can be no assurance that such laws,
regulations or interpretations will not change in the future or that additional
laws and regulations will not be enacted. The ability of the Company to operate
profitably will depend in part upon the Company and its affiliated Physician
Organizations obtaining and maintaining all necessary licenses and other
approvals and operating in compliance with applicable health care regulations.
 
    Subject to limited exceptions, federal anti-kickback legislation prohibits
the offer, payment, solicitation or receipt of any form of remuneration, whether
direct or indirect, in return for, or in order to induce: (i) the referral of a
person for services; (ii) the furnishing or arranging for the furnishing of
items or
 
                                       60
<PAGE>
services; or (iii) the purchase, lease or order of, arranging or recommending
purchasing, leasing or ordering of, any item or service, in each case,
reimbursable under any federally-funded health care programs, including the
Medicare or Medicaid programs. A violation of the federal anti-kickback statute
generally requires several elements: (i) the offer, payment, solicitation, or
receipt of remuneration; (ii) the intent to induce referrals; and (iii) the
ability of the parties to make or influence referrals of patients for services
reimbursable under federally-funded health care programs or to provide items
reimbursable under such programs. Noncompliance with, or violation of, the
federal anti-kickback legislation can result in exclusion from the Medicare and
Medicaid programs and civil and criminal penalties. Many states, including
California, have similar anti-kickback prohibitions with similar penalties.
 
    In addition to the statutory exceptions to the federal anti-kickback
statute, the accompanying regulations set forth certain "safe harbor"
arrangements which are protected from scrutiny under the legislation. Although
satisfaction of the requirements of any of these safe harbors generally provides
a guarantee of compliance with the law, failure to meet the safe harbor does not
necessarily mean that a transaction violates the prohibitions. Included among
the safe harbor regulations is a safe harbor for management contracts which meet
certain criteria. The Company believes its activities are not in violation of
the anti-kickback legislation. Further, the Company believes that the business
operations of its affiliated Physician Organizations do not involve the offer,
payment, solicitation or receipt of remuneration to induce referrals of patients
because compensation arrangements between the Physician Organizations and the
primary care physicians who make referrals are designed to discourage referrals
to the extent they are medically unnecessary. These physicians are paid either
on a capitation or fee-for-service basis and do not receive any financial
benefit from making referrals. Although the Company believes its activities do
not violate the anti-kickback legislation, no assurances can be given that its
operations will not ultimately be construed to fall within the ambit of such
prohibitions.
 
    Federal legislation also restricts the ability of physicians to refer
patients to entities in which they or one of their immediate family members has
an ownership interest or compensation arrangement for the provision of certain
designated health services reimbursable under federally-funded health plans.
Further, the entity providing health care services is also prohibited from
presenting, or causing to be presented, a claim or bill for the designated
services furnished pursuant to a prohibited referral. Penalties for violations
include, without limitation, denial of reimbursement, forfeiture of amounts
collected in violation of the provision, civil monetary penalties and exclusion
from the Medicare and Medicaid programs. Many states, including California, have
similar self-referral laws which provide for similar penalties.
 
    The Company believes that its business arrangements do not involve the
referral of patients to entities with whom referring physicians have an
ownership interest or compensation arrangement within the meaning of federal and
state self-referral laws, because referrals are made directly to other providers
rather than to entities in which referring physicians have an ownership interest
or compensation arrangement. The Company further believes its financial
arrangements with physicians fall within various exceptions to state and federal
self-referral laws, including exceptions for ownership or compensation
arrangements with certain managed care organizations and for physician incentive
plans that limit referrals. In addition, the Company believes that the methods
that it uses to acquire existing physician organizations and to recruit new
physicians do not violate such laws and regulations.
 
    The federal government continues to engage in increased scrutiny of joint
ventures and other transactions among health care providers in an effort to
reduce potential fraud and abuse relating to patients of federal health care
programs, and no assurances can be given that the Company's operations will not
fall within the ambit of the anti-kickback or self-referral prohibitions or that
other laws or regulations will not be enacted that will have a material adverse
effect on the Company. The application of the anti-kickback and self-referral
laws and regulations to many kinds of business transactions in the health care
industry has not been subject to regulatory or judicial interpretation. Should
any of the Company's business arrangements be deemed to constitute arrangements
designed to induce the referral of Medicare or Medicaid patients or to involve
referrals to entities with which the referring physician has an ownership
 
                                       61
<PAGE>
interest or compensation arrangement, then such arrangements could be viewed as
violating anti-kickback or self-referral laws and regulations. A determination
of liability under any such law could have a material adverse effect on the
Company's financial condition and results of operations.
 
    Upon written request, the OIG is authorized to issue advisory opinions,
which clarify whether a proposed arrangement implicates the Medicare/Medicaid
anti-kickback statute and, if so, whether it fits within a statutory exception
or safe harbor. In April 1998, the OIG issued an advisory opinion under the
Medicare/Medicaid anti-kickback statute regarding a proposed management services
contract between a medical practice management company and a primary care
physician practice. Pursuant to the agreement, the management company would
provide facilities, equipment, billing services, and marketing services to the
physician practice, as well as negotiate on behalf of the physician practice
with managed care plans and establish specialty physician networks to which
referrals may be made by the primary care physicians. The compensation paid to
the management company included a fee based on a percentage of the physician
practice's net revenues, including revenues from business derived from managed
care contracts arranged by the management company. The OIG concluded that the
proposed arrangement was problematic because: (1) percentage of revenue
compensation arrangements may include financial incentives to increase patient
referrals since the revenue includes revenue from business derived from managed
care contracts arranged by the management company and the management company
would be establishing networks of specialist physicians to whom the primary care
physicians would be required to make referrals in some circumstances; (2) the
proposed arrangement contained no safeguards against utilization which is
particularly problematic in light of the proposed establishment of provider
networks with required referral arrangements; and (3) percentage of revenue
compensation arrangements may include financial incentives that encourage
abusive billing practices since the management company had an incentive to
maximize the physician practice's revenue. However, the OIG did not rule that
the proposed contract was illegal, noting that it had not received any
information on the proposed arrangement from the management company and that the
legality of the arrangement might depend on the intent of the parties. After
studying the legal implications of the advisory opinion, the Company has revised
its standard management agreement with its affiliated physician organizations to
specify a flat fee payable on a monthly basis as compensation for marketing
services. The Company is also in the process of adopting a corporate compliance
program designed to prevent violation of the anti-kickback statute in both its
acquisitions and day-to-day operations. The Company believes that, although it
continues to receive percentage of revenue remuneration under management
services agreements, it is not in a position to make or influence the referral
of patients or services reimbursed under government programs to the Physician
Organizations, and therefore, believes that its compensation arrangements do not
violate the anti-kickback statute. However, there can be no assurances that the
OIG or any other health care regulatory agency will not interpret the Company's
compensation arrangements under its management services agreements to be in
violation of the prohibitions of the anti-kickback statute.
 
    Federal and state laws prohibit anti-competitive conduct among health care
providers within the same or overlapping markets, such as price-fixing
agreements between competitors, agreements allocating or dividing geographic
market areas in which competitors will separately operate, or agreements to
boycott or refuse to deal with another competitor. Such antitrust laws also
prohibit the monopolization of markets, or mergers and other agreements among
competitors intended to monopolize markets. Because the Physician Organizations
remain separate legal entities, they may be deemed to be competitors, and
therefore may be subject to these antitrust laws. In such case, their
activities, including the coordination of their contracting efforts, could
violate antitrust prohibitions. The Company intends to comply with state and
federal antitrust laws, but there is no assurance that the review of the
Company's operations by courts or regulatory authorities will not result in a
determination that could adversely affect the operation of the Company and the
Physician Organizations.
 
    Federal and state laws regulate insurance companies, HMOs and other managed
care organizations. Generally, these laws apply to entities that accept
financial risk. Certain of the risk arrangements entered
 
                                       62
<PAGE>
into by the affiliated Physician Organizations could be characterized by some
states as the business of insurance or of an HMO. The Company, however, believes
that the acceptance of capitation payments by a health care provider does not
constitute the conduct of the business of insurance or of an HMO. The Company
believes that it is in compliance with these laws in California where it
conducts its business, but there can be no assurance that interpretations of
these laws by the regulatory authorities in California will not require
licensure or a restructuring of some or all of the Company's operations. In the
event that the Company is required to become licensed under these laws, the
Company would be required to obtain a license under Knox-Keene and comply with
the requirements thereunder as described under "--Regulatory Requirements for a
Limited License Knox-Keene Health Plan and Medicare Health Plan."
 
    REGULATORY REQUIREMENTS FOR A LIMITED LICENSE KNOX-KEENE HEALTH PLAN AND
MEDICARE HEALTH PLAN.  To operate a health plan in the State of California, an
organization must apply for a license under Knox-Keene from the DOC. All
Knox-Keene health care service plan applicants must demonstrate the projected
financial viability of the plan in the marketplace, and that the proposed
business will "break even" within a reasonable period of time. Traditionally,
this is accomplished through market feasibility studies and letters of interest
that support enrollment projections, actuarial studies that justify medical
utilization costs, and comprehensive financial projections. The DOC requires all
plans to demonstrate fiscal soundness and full assumption of financial risk,
which includes (i) demonstrating that health care rates and charges are
financially sound and will provide for achievement and maintenance of a positive
cash flow; (ii) showing that adequate working capital will be available,
including provisions for contingencies; (iii) providing adequate insurance for
extraordinary losses; (iv) substantiating enrollment projections; (v) projecting
financial viability; (vi) listing the entity's sources of tangible net equity;
and (vii) demonstrating that the overall business plan has been validated by
feasibility studies and actuarial reports.
 
    The organization must also meet certain quality assurance and utilization
review standards and will be subject to audit by its contracting HMOs or HCFA
(in the case of a Medicare Health Plan). These audits may be performed by the
individual HMOs or HCFA, or by an independent auditor on behalf of the HMO or
HCFA, as applicable. The organization must also implement grievance and
complaint procedures to identify, evaluate and remedy problems relating to
access, continuity and quality of care, and utilization management, and to
document that provider reimbursement exceeds the costs of services expected to
be provided. The organization must also continually demonstrate sufficient
organizational and administrative capacity.
 
    Newly licensed plans are required to maintain a minimum tangible net equity
of $1,000,000. The DOC also expects that a plan will have at least another
$2,000,000 to $3,000,000 available for working capital and expansion needs,
including an amount sufficient to pay for all obligations incurred through a
projected break even date. After the plan becomes operational, tangible net
equity requirements may exceed the above-listed amounts if the annualized
revenues or enrollment of the plan exceed certain criteria.
 
    Once an entity has obtained a license under Knox-Keene, it will be subject
to continuing regulation by the DOC; to assume full risk for the provision of
hospital, physician and ancillary health care services to enrollees, it must
continue to meet certain operating requirements. These requirements include
significant data reporting specifications, particularly regarding financial
viability, quality management and general organizational and administrative
capacity. These requirements may involve significant investment in management
information systems and organizational and administrative capacity.
 
    In addition to compliance with the foregoing requirements of the DOC, a
Medicare Health Plan is also required to meet certain requirements of HCFA.
These requirements generally cover similar areas (finance, quality management
and organizational and administrative capacity) that the DOC underscores.
 
    GENERAL REGULATORY REQUIREMENTS.  In addition to the regulations referred to
above, significant aspects of the Company's and its affiliated physician
organizations' operations are subject to state and federal statutes and
regulations governing workplace health and safety, dispensing of controlled
substances and the disposal of medical waste. The Company's operations may also
be affected by changes in ethical
 
                                       63
<PAGE>
guidelines and operating standards of professional and trade associations such
as the American Medical Association. Accordingly, changes in existing laws and
regulations, adverse judicial or administrative interpretations of such laws and
regulations or enactment of new legislation could have a material adverse effect
on the operating results and financial condition of the Company.
 
MALPRACTICE INSURANCE
 
    The Company currently is not covered by malpractice insurance but does carry
general liability insurance. Each of the Company's affiliated medical groups
maintains malpractice insurance as well as managed care professional liability
insurance for the corporate entity and its employees. The Company requires all
physicians who contract with an affiliated independent practice association to
carry malpractice insurance coverage. See "Legal Proceedings" below.
 
EMPLOYEES
 
    At June 30, 1998, Prospect Medical Holdings had approximately 10 full-time
employees. Prospect Medical Systems had approximately 134 full-time and 17
part-time employees. Sierra Medical Management had approximately 95 full-time
and 5 part-time employees. None of such employees is subject to a collective
bargaining agreement. Management believes that its employee relations are good.
 
PROPERTIES
 
    The Company does not own any real property. The Company or its affiliated
Physician Organizations currently lease space for medical and administrative
offices as described in the following charts. The space described below may be
shared space used for medical and administrative office purposes or separate
space used for medical and/or administrative offices located at the same address
and may be leased under the same or separate leases.

    Sierra Medical Group owns an approximately 10,000 square foot undeveloped
lot located near its offices in Palmdale, California that is currently used as a
parking lot.
 
    The Company has entered into a lease for approximately 19,446 square feet in
Santa Ana to replace the general office space leased in Santa Ana, California
and in Yorba Linda, California. The Company believes that the new general office
space, together with the general office space that will continue to be leased by
the Company, will be sufficient to serve its operational needs for the
foreseeable future, although the growth which is intended as part of the ongoing
business plan of the combined companies, if successful, may require additional
space. Further, as the Company affiliates with, and the Physician Organizations
acquire, additional physician organizations, management expects that the Company
will enter into additional medical office space leases.
 
LEGAL PROCEEDINGS
 
    In addition, the Company is a party to certain legal actions arising in the
ordinary course of business. In the opinion of the Company's management,
liability, if any, under these claims is adequately covered by insurance or will
not have a material effect on the Company's financial position or results of
operations.
 
    Effective July 1, 1998, a settlement agreement was entered into among the
Company, Prospect Medical Group, Yorba Linda Medical Group, and the
physician-shareholders of Yorba Linda Medical Group (the "Yorba Linda Settlement
Agreement"). On July 31, 1998, certain parties related to the Company filed a
motion to enforce the Yorba Linda Settlement Agreement (the "Company's Motion"),
in a pending action entitled DENICOLA V. MCGINTY, Orange County Superior Court
Case No. 795018. The opposing parties, consisting of Yorba Linda Medical Group
and the members of its Board of Directors, responded by filing a cross-motion
for enforcement (the "YLMG Motion"). On or about August 14, 1998, prior to a
ruling on either motion, Yorba Linda Medical Group and its remaining
physician-shareholders filed a lawsuit against the Company, Prospect Medical
Group, Prospect Medical Systems, Dr. DeNicola
 
                                       66
<PAGE>
and certain other individual physicians seeking damages and injunctive relief
based upon allegations of breach of contract, fraud and certain related claims
with respect to the Yorba Linda Settlement Agreement (MCGINTY V. PROSPECT
MEDICAL GROUP, ET AL., Orange County Superior Court Case No. 798208 (the
"MCGINTY Lawsuit")). The court on September 1, 1998 granted the material
portions of the Company's Motion to enforce the Yorba Linda Settlement
Agreement, denied the material portions of the YLMG Motion, and ordered the
parties to mediate the remaining unresolved issues. The Company believes the
MCGINTY Lawsuit is without merit and is barred by the Yorba Linda Settlement
Agreement. See "Risk Factors-- Recent Settlement Agreement with Yorba Linda
Medical Group" and "Business of the Company--History of the Company" for further
discussion of the recently executed Yorba Linda Settlement Agreement.

DIRECTORS AND EXECUTIVE OFFICERS
 
    The Board of Directors is classified into three classes. The first class was
elected pursuant to stockholder written consent effective as of the 1996 Merger
to serve until the annual meeting of stockholders to be held in 1997 ("Class I
Directors"), the second class to serve until the annual meeting of stockholders
to be held in 1998 ("Class II Directors") and the third class to serve until the

Directors will be elected by the stockholders of the Company at each annual
meeting of stockholders and serve until the third annual meeting of stockholders
following their election and until their successors are elected and qualified or

been removed from office. There are no family relationships between any
directors or current officers of the Company. Officers serve at the discretion
of the Board of Directors.
 
    The following sets forth certain biographical information, the present

issuance of an order by the SEC concerning the late filing of reports of
transactions in the securities of Century MediCorp of which Dr. Terner was then
Chairman of the Board of Directors and Chief Executive Officer. The order found
that Dr. Terner filed reports on Form 4 under Section 16(a) of the Securities
Exchange Act of 1934, as amended, in an untimely fashion between 1987 and 1991
and required that Dr. Terner cease and desist from any further late filings.
 
    On June 30, 1997, Dr. Terner consented, without admitting or denying any of
the allegations in a complaint relating to an insider trading investigation by
the SEC, except as specifically set forth therein, to the entry of a final
judgment of permanent injunction and other relief. The SEC's investigation

with Foundation Health, a California Health Plan. The judgment permanently
restrained and enjoined Dr. Terner from employing any fraudulent device, scheme
or artifice, making material misstatements or omitting material statements of
fact or engaging in fraudulent or deceitful acts, practices or courses of
business in violation of Section 10(b) of the 1934 Act and Rule 10b-5
thereunder. No allegations were made that Dr. Terner had personally engaged in

    Certain of the physician executive officers of the Company and its
subsidiaries are the sole stockholder and officers and directors of Prospect
Medical Group, Santa Ana/Tustin Physicians Group, Sierra Medical Group and
Pegasus Medical Group, all of which are Physician Organizations.
 
    The ownership, control and continuous management of the Physician
Organizations are governed in part by agreements (the "Assignable Option
Agreements") entered into by the Company's subsidiaries, the stockholder of the
Physician Organization and each such Physician Organization. The Assignable
Option Agreements prohibit the transfer of stock of the applicable Physician
Organization without the prior written consent of the Company's subsidiary. Each
Assignable Option Agreement terminates upon termination of the management
services agreement between the Physician Organization and the Company's
subsidiary that are parties to such Assignable Option Agreement.
 
    Each Assignable Option Agreement grants to the Company's subsidiary an
assignable right to designate a successor physician(s), which person(s) must be
duly licensed physicians in the State of California or otherwise permitted by
law to be a shareholder in a professional corporation, to purchase all or part
of the stock of the Physician Organization in its sole discretion. Gregg
DeNicola, M.D., who is a stockholder, director and President of the Company, is
the sole shareholder, President, Chief Financial Officer and Secretary of
Prospect Medical Group. Jacob Y. Terner, M.D., who is a stockholder, director,
Chairman of the Board and Chief Executive Officer of the Company, is a Vice
President of Prospect Medical Group. Prospect Medical Group is the sole
shareholder of the other Physician Organizations.
 
    During July and September 1997, the Company made two loans of $5,000,000
each to Prospect Medical Group in connection with the acquisitions of Santa
Ana/Tustin Physicians Group and Sierra Medical Group. In October 1997, the
Company made a loan of $700,000 to Pegasus Medical Group in connection with the
acquisition of Western Medical Group. In June 1998, the Company made a loan of
$25,000 to Sierra Medical Group in connection with the acquisition of assets of
Antelope Valley Medical Group. None of such amounts have been repaid. Of these
loans, a loan for a portion of one $5,000,000 loan (in the principal amount of
$3,000,000), a loan for $5,000,000 and a loan for $700,000 are required to be
repaid on or before July 3, 1999. These loans were structured to require
repayment on July 3, 1999 in accordance with the terms of the Facility. The
Company may seek to extend the maturity of these loans in connection with an
extension of the maturity of the Facility, which will be subject to the consent
of the Bank. Each of these three loans bears interest at the rate of 6% per
annum. The remaining loans currently bear interest at the rate of 10% per annum
and are repayable on demand. Since these loans are payable from revenues of the
affiliated physician organizations, the Company does not anticipate that
sufficient funds will available to repay such loans or that such organizations
will be able to obtain financing to repay these loans. As the Company prepares
its financial statements on a consolidated basis for financial statement
reporting purposes, these loans are eliminated in the consolidation. See "Risk
Factors--Need for Additional Capital." All of the loans are collateralized by
the accounts and rights to payment of the applicable Physician Organization.
 
    So long as the Facility is outstanding, the Company is required to comply
with the covenants in its agreements with the Bank. The Facility prohibits the
Company from incurring any further debt without the approval of the Bank.

(1) Thomas A. Maloof resigned as Chief Financial Officer of Prospect Medical
    Holdings as of February 28, 1998.
 
(2) At September 30, 1997, there was no active trading market for the Company's
    Common Stock. Therefore, for illustrative purposes, valuations at that date
    have been based on the $2.00 per share price in a recent private sale of the
    Company's Common Stock.
 
STOCK OPTION PLAN
 
    The Board of Directors has recently approved the Stock Option Plan. A total
of 166,000 shares of the Company's Common Stock has been reserved for issuance
upon the exercise of options pursuant to the Stock Option Plan. Such shares may
be either authorized but unissued shares or shares acquired by the Company and
held in its treasury. The Stock Option Plan will be administered by the
Compensation Committee of at least two members of the Board of Directors, who
are not officers or employees of the Company and who are appointed by the Board
of Directors, or by the entire Board of Directors.
 
    Each option granted under the Stock Option Plan will be a qualified
incentive stock option evidenced by a Stock Option Agreement between the Company
and the optionee. The price to be paid for shares of stock upon exercise of each
option will be determined by the Compensation Committee at the time such option
is granted, but shall be not less than the fair market value of the stock, as
determined in accordance with the Stock Option Plan, on the date the option is
granted. The maximum term of each option will be ten years. The aggregate fair
market value of the Common Stock with respect to which options are first
exercisable by any single optionee in any calendar year will be limited to
$100,000.
 
    An option under the Stock Option Plan will terminate in the event the holder
ceases to be employed by the Company, except in the case of death or disability.
In the case of death or disability, the option will be permitted to be exercised
within 12 months by the holder, holder's legal representative, executor,
administrator, legatee or heirs, as the case may be. The Board has approved the
grant of options to purchase 111,000 shares of Common Stock under the Stock
Option Plan. The Company may issue options to Mr. Kahn and Ms. Vigil under the
Stock Option Plan in replacement for the options previously granted to him or
her.

Company effective upon the change of control of management on July 31, 1996.
Under the terms of this agreement, as amended, Dr. Terner received no
compensation until September 30, 1997, after which time he is to be compensated

                          DESCRIPTION OF CAPITAL STOCK
 
GENERAL
 
    Prospect Medical Holdings is a Delaware corporation. The Company has two
classes of stock: Common Stock and Preferred Stock.
 
COMMON STOCK
 
    The Company's Certificate of Incorporation currently authorizes the issuance
of 40,000,000 shares of $.01 par value Common Stock, of which 4,449,395 of such
shares are currently validly issued and outstanding, and 904,559 shares are
reserved for issuance (i) upon the exercise of outstanding options and warrants,
(ii) pursuant to the proposed Stock Option Plan and (iii) in connection with a
completed medical asset acquisition. Holders of Common Stock are entitled to one
vote, either in person or by proxy, for each share held of record on all matters
submitted to a vote of stockholders.
 
    Except as otherwise provided by law and by the Company's Certificate of
Incorporation, action can be taken by a majority of shares entitled to vote at a
meeting. Holders of Common Stock are entitled to dividends when and as may be
declared by the Board of Directors out of funds legally available therefor, and,
in the event of liquidation or dissolution of the Company, are entitled to share
ratably in the assets of the Company remaining after payment of liabilities and
payment in respect of any preferred stock. Holders of Common Stock have no
conversion, preemptive or other subscription rights, and there are no redemption
or sinking fund provisions with respect to the Common Stock. The outstanding
shares of Common Stock of the Company are fully paid and nonassessable.
 
PREFERRED STOCK
 
    The Company's Certificate of Incorporation currently authorizes the issuance
of 1,000,000 shares of preferred stock, $.01 par value ("Preferred Stock"),
which may be issued from time to time in one or more series as determined by the
Board of Directors without stockholder approval. The Board of Directors has been
authorized to fix the designation, powers, preferences, and rights of the shares
of each such series and any qualifications, limitations or restrictions thereon.
Preferred Stock could be given voting and conversion rights which would dilute
the voting power and equity of holders of Common Stock and could rank prior to
the Common Stock or a newly created series of Preferred Stock with respect to
dividend rights, rights on liquidation or other rights. The Company has no
current plans for the issuance of any of the shares of authorized Preferred
Stock, and as of the date of this Prospectus, no shares of Preferred Stock are
outstanding.
 
    Such Preferred Stock could create impediments to persons seeking to gain
control of the Company, although there is no present intention to do so. The
issuance of such shares could prevent holders of the Company's Common Stock from
receiving a premium for their shares from a potential third-party acquiror. See
"Risk Factors--Anti-Takeover Effect of Certain Charter and Other Provisions."
 
WARRANTS
 
    The following summary description of certain provisions of the Warrants is
believed to reflect the material provisions of the Warrants but is not
necessarily complete and is qualified in all respects by reference to the actual
text of the Warrant Agreement between the Company and American Stock Transfer &
Trust Company (the "Warrant Agent"), a copy of which has been filed as an
exhibit to the Registration Statement of which this Prospectus is a part. See
"Available Information."
 
    EXERCISE PRICE AND TERMS.  Each Warrant entitles the registered holder
thereof to purchase, at any time commencing       , 1999 [the first anniversary
of the effective date of the registration statement filed with respect to the
Warrants]until       , 2003 [the day immediately preceding the fifth anniversary
of such effective date], one share of Common Stock at a price of $8.40 per
share, subject to adjustment in
 
                                       76
<PAGE>
accordance with the anti-dilution and other provisions referred to below. The
holder of any Warrant may exercise such Warrant by surrendering the certificate
representing the Warrant to the Warrant Agent, with the subscription form
thereon properly completed and executed, together with payment of the exercise
price. No fractional shares will be issued upon the exercise of the Warrants.
The exercise price of the Warrants bears no relationship to any objective
criteria of value and should in no event be regarded as an indication of any
future market price of the Securities offered hereby.
 
    ADJUSTMENTS.  The exercise price and the number of shares of Common Stock
purchasable upon the exercise of the Warrants are subject to adjustment upon the
occurrence of certain events, including stock dividends, stock splits,
combinations or reclassifications of the Common Stock or the sale by the Company
of its Common Stock or other securities convertible into Common Stock at a price
below the exercise price of the Warrants. Additionally, an adjustment would be
made in the case of a reclassification or exchange of Common Stock,
consolidation or merger of the Company with or into another corporation (other
than a consolidation or merger in which the Company is the surviving
corporation) or sale of all or substantially all of the assets of the Company,
in order to enable warrantholders to acquire the kind and number of shares of
stock or other securities or property receivable in such event by a holder of
the number of shares of Common Stock that might otherwise have been purchased
upon the exercise of the Warrant.
 
    REDEMPTION PROVISIONS.  Commencing       , 1999 [the first anniversary of
the effective date of the registration statement filed with respect to the
Securities], the Warrants are subject to redemption by the Company, in whole but
not in part, at $.10 per Warrant on not less than thirty (30) days' prior
written notice to the warrantholders, if the average closing sale price of the
Common Stock as reported on the American Stock Exchange equals or exceeds $18.00
per share for any twenty (20) trading days within a period of thirty (30)
consecutive trading days ending on the fifth trading day prior to the date of
the notice of redemption. In the event the Company exercises the right to redeem
the Warrants, such Warrants will be exercisable until 5:00 p.m. (New York time)
on the business day immediately preceding the date for redemption fixed in such
notice. If any Warrant called for redemption is not exercised by such time, it
will cease to be exercisable and the holder will be entitled only to the
redemption price.
 
    TRANSFER, EXCHANGE AND EXERCISE.  The Warrants are in registered form and
may be presented to the Warrant Agent for transfer, exchange or exercise at any
time on or prior to their expiration date which is the day immediately preceding
the fifth anniversary of the date of this Prospectus, at which time the Warrants
will become wholly void and of no value. If a market for the Warrants develops,
the holder may sell the Warrants instead of exercising them. There can be no
assurance, however, that a market for the Warrants will develop or continue.
 
    WARRANTHOLDER NOT A STOCKHOLDER.  The Warrants do not confer upon holders
thereof any voting, dividend, or other rights as stockholders of the Company.
 
    MODIFICATION OF WARRANTS.  The Company and the Warrant Agent may make such
modifications to the Warrants as they deem appropriate to cure ambiguities or to
make certain corrections or as they deem necessary or desirable that do not
adversely affect the interests of the warrantholders; any other modifications,
supplements or alterations can only be made with the consent in writing of the
warrantholders representing not less than 66 2/3% of the Warrants then
outstanding. The Company may, in its sole discretion, lower the exercise price
of the Warrants for a period of not less than thirty (30) days on not less than
thirty (30) days' prior written notice to the warrantholders and the
Representative. Modification of the number of securities purchasable upon the
exercise of any Warrant, an increase in the exercise price or acceleration of
the expiration date with respect to any Warrant requires the consent of the
applicable warrantholder.
 
    The Warrants are not exercisable unless, at the time of the exercise, the
Company has a current prospectus covering the shares of Common Stock issuable
upon exercise of the Warrants, and such shares
 
                                       77
<PAGE>
have been registered, qualified or deemed to be exempt under the securities or
"blue sky" laws of the state of residence of the exercising holder of the
Warrants.
 
LISTING ON AMERICAN STOCK EXCHANGE
 
    There is no established public trading market for the Company's Common
Stock. See "Risk Factors-- Inactive Prior Market for the Common Stock; No
Assurance of American Stock Exchange Listing." The Company intends to make an
application for a listing on the American Stock Exchange. As of the date of this
Prospectus, to obtain an American Stock Exchange listing a company must have a
three-year history of operations; and minimum public distribution of 500,000
shares together with a minimum of 800 public holders or 1,000,000 shares
together with a minimum of 400 public holders; the minimum bid price for the
listed securities must be $3.00 per share; the minimum market value of the
public float (the shares held by non-insiders) must be at least $15,000,000; and
stockholders equity must be at least $4,000,000. In the event that the Company
is able to sell all 3,000,000 Shares being offered hereby, it is hoped that the
Company will (on a pro forma basis) satisfy all American Stock Exchange
requirements for new listing. There can be no assurances however, as to when, if
ever, such a listing may be obtained or if obtained, that an active trading
market will develop. See "Risk Factors--Inactive Prior Market for the Common
Stock; No Assurance of American Stock Exchange Listing."
 
CERTAIN PROVISIONS OF THE COMPANY'S CERTIFICATE OF INCORPORATION AND BYLAWS
 
    Under the Company's Certificate of Incorporation, the Board of Directors is
divided into three classes which are to be as nearly equal in number as
reasonably possible. The initial term of office of the first class expired at
the 1994 annual meeting of stockholders, the initial term of office of the
second class expired at the 1995 annual meeting of stockholders and the initial
term of office of the third class expired at the 1996 annual meeting of
stockholders. At each annual meeting of stockholders coinciding with the
expiration of the term of office of class of directors, successor directors are
elected for a term of office to expire at the third succeeding annual meeting of
stockholders after their election. Under the Company's Certificate of
Incorporation, a director holds office until the annual meeting of stockholders
for the year in which his term expires and until his successor shall be elected
and shall qualify. The Company has not held an annual meeting of its
stockholders to elect members to the Board of Directors since the 1996 Merger
that was consummated on July 31, 1996. Under the Delaware General Corporation
Law, or under the California General Corporation Law, to the extent that such
law is applicable, if an annual meeting has not been held to elect directors,
for a period of 13 months (15 months under California law), upon application of
any stockholder or director (a director may apply only under Delaware law), the
Court of Chancery in the State of Delaware or the Superior Court in the State of
California may summarily order a meeting to be held to elect directors. The
directors elected at the 1996 Merger have continued to serve as directors, other
than Thomas A. Maloof who has since resigned. Having a classified Board of
Directors may make it more difficult to effect a change in control of the
Company than if the Board of Directors were not classified with staggered terms.
See "Risk Factors--Anti-Takeover Effect of Certain Charter and Other
Provisions."
 
    Under the Company's Certificate of Incorporation special meetings of the
stockholders for any purpose or purposes may be called at any time only by the
Board of Directors, the Chairman of the Board, or by the Chief Executive Officer
or President of the Company. The Company's Certificate of Incorporation further
provides that any action required or permitted to be taken at any annual or
special meeting of stockholders may not be taken by a written consent of the
stockholders pursuant to the Delaware Corporation Law, unless such action by
written consent is authorized by resolution of the Board of Directors of the
Company. Since the stockholders of the Company do not have the right to call a
special stockholders' meeting, this requirement in the Company's Certificate of
Incorporation for Board of Directors authorization of stockholders' action by
written consent eliminates the ability of stockholders of the Company to take
any actions independently of the Board of Directors of the Company. See "Risk
Factors--Anti-Takeover Effect of Certain Charter and Other Provisions."
 
                                       78
<PAGE>
    The Company's Certificate of Incorporation also provides that certain
provisions thereof may not be amended, altered, changed or repealed without the
affirmative vote of the holders of not less than 75% of the outstanding shares
of Company stock entitled to vote. Under the Company's Certificate of
Incorporation and the Company's Bylaws, the Company's Bylaws may be adopted,
amended or repealed by the affirmative vote of the holders of 75% of the
outstanding shares and, subject to the rights of the Company's stockholders to
adopt, amend or repeal bylaws pursuant to the Delaware Corporation Law, the
Board of Directors may adopt, amend or repeal the Company's Bylaws.
 
LIMITATION OF LIABILITY OF DIRECTORS
 
    Under the Delaware Corporation Law, a director's liability cannot be
eliminated or limited: (i) for breaches of duty of loyalty, (ii) for acts or
omissions not in good faith or which involve intentional misconduct or a knowing
violation of law, (iii) for the payment of unlawful dividends or expenditure of
funds for unlawful stock purchases or redemptions, or (iv) for transactions from
which the director derived an improper personal benefit. Under the Company's
Certificate of Incorporation no director of the Company shall be personally
liable to the Company or its stockholders for monetary damages for any breach of
fiduciary duty by such director as a director. The Company's Certificate of
Incorporation further provides that notwithstanding the foregoing a director
shall be liable to the extent provided by applicable law as described in clauses
(i) through (iv) above. This provision, in effect, eliminates the rights of the
Company and its stockholders (through stockholders' derivative suits on behalf
of the Company) to recover monetary damages from a director for breach of his or
her fiduciary duty of care as a director, except in the situations set forth in
clauses (i) through (iv) above. In addition, the Certificate of Incorporation
does not alter the liability of directors under federal securities laws, and
does not limit or eliminate the rights of the Company or any stockholder to seek
non-monetary relief, such as an injunction or rescission, in the event of a
breach in a director's duty of care. The Certificate of Incorporation requires
the Company to indemnify all directors and officers of the Company to the
fullest extent permitted by law, provided, however, that, with certain limited
exceptions, the Company will only indemnify an officer or director in connection
with a proceeding that was authorized by the Board of Directors. The Bylaws also
authorize the Company to indemnify and advance indemnification expenses to the
Company's officers and directors.
 
    The Company's Certificate of Incorporation further provides that if and to
the extent final legal determination is ever made that and for so long as
Section 204(a)(10) or Section 317 of the California Corporations Code are
applicable to the Company, the provision of the Company's Certificate of
Incorporation relating to limitation of a director's liability for monetary
damages and the provisions relating to indemnification set forth therein will
apply only to the extent permissible under Sections 204(a)(10) and 317 of the
California Corporations Code.
 
TRANSACTIONS WITH INTERESTED PERSONS
 
    Section 203 of the Delaware Corporation Law regulates certain "business
combinations" involving Delaware corporations. Generally, Section 203 of the
Delaware Corporation Law prohibits a publicly held Delaware corporation from
engaging in a broad range of "business combinations" with an "interested
stockholder" (defined generally as a person owning 15% or more of the
corporation's outstanding voting stock) for three years following the date such
person became an interested stockholder unless (i) before the person becomes an
interested stockholder, the transaction resulting in such person becoming an
interested stockholder or the business combination is approved by the board of
directors of the corporation, (ii) upon consummation of the transaction which
resulted in the stockholder becoming an interested stockholder, the interested
stockholder owned at least 85% of the outstanding voting stock of the
corporation (excluding shares owned by directors who are also officers of the
corporation or shares held by employee stock plans that do not provide employees
with the right to determine confidentially whether
 
                                       79
<PAGE>
shares held subject to the plan will be tendered in a tender offer or exchange
offer) or (iii) on or after such date on which such person became an interested
stockholder the business combination is approved by the board of directors and
authorized at an annual or special meeting, and not by written consent, by the
affirmative vote of at least 66 2/3% of the outstanding voting stock excluding
shares owned by the interested stockholder. The restrictions of Section 203 do
not apply, among other reasons, if a corporation, by action of its stockholders,
adopts an amendment to its certificate of incorporation or bylaws expressly
electing not to be governed by Section 203, provided that, in addition to any
other vote required by law, such amendment to the certificate of incorporation
or bylaws must be approved by the affirmative vote of a majority of the shares
entitled to vote. Moreover, an amendment so adopted generally is not effective
until twelve months after its adoption and does not apply to any business
combination between the corporation and any person who became an interested
stockholder of such corporation on or prior to such adoption. The Company's
Certificate of Incorporation and Bylaws do not currently contain any provisions
electing not to be governed by Section 203 of the Delaware Corporation Law.
 
    These provisions are intended to make unsolicited takeover bids more
difficult, even if desired by holders of a majority of the outstanding shares.
However, these provisions also make it more difficult to remove incumbent
directors.
 
    Section 203 applies only to Delaware corporations that have a class of
voting stock that is listed on a national securities exchange, are quoted on an
inter-dealer quotation system such as Nasdaq or are held of record by more than
2,000 stockholders. Since the Company currently does not have a class of voting
stock that is listed on a national securities exchange or is quoted on an
inter-dealer quotation system such as Nasdaq, and has fewer than 2,000
stockholders of record, Section 203 does not currently apply to the Company.
Following the Offering, however, if the Company's application for listing on the
American Stock Exchange is granted or the Company has 2,000 or more stockholders
of record, Section 203 would apply to the Company in the absence of an amendment
to the Company's Certificate of Incorporation or Bylaws as described above.
 
    Section 203 is subject to possible challenge in takeover disputes, and it is
not yet clear whether and to what extent its constitutionality will be upheld by
the courts. Although the United States District Court for the District of
Delaware has consistently upheld the constitutionality of Section 203, the
Delaware Supreme Court has not yet considered the issue. The Company believes
that so long as the constitutionality of Section 203 is upheld, Section 203 will
(if applicable to the Company) encourage any potential acquiror to negotiate
with the Company's Board of Directors. Section 203 would also have the effect of
limiting the ability of a potential acquiror to make a two-step bid for the
Company in which all stockholders are not treated equally. The application of
Section 203 to the Company would confer upon the Board of Directors the power to
reject a proposed business combination, even though a potential acquiror may be
offering a substantial premium for the Company's shares over the then current
market price. Section 203 could also discourage certain potential acquirors
unwilling to comply with its provisions.
 
    Apart from the restrictions set forth in the Delaware Corporation Law
Section 203, the Company Certificate includes restrictions on transactions
between "Interested Persons" (as described below) and the Company. In general,
these provisions prevent an "Interested Person" from engaging in these business
combinations with the Company, unless certain stockholder approvals, including
approval by stockholders other than the interested stockholders, have been
obtained.
 
    Under the Company Certificate, an "Interested Person" is any person, firm or
corporation, or any group thereof, acting or intending to act in concert,
including any person directly or indirectly controlling or controlled by or
under direct or indirect common control with such person, firm, or corporation
or group, which owns of record or beneficially, directly or indirectly, five
percent (5%) or more of the shares of any class of voting securities of the
Company.
 
    Under the Company Certificate, except as set forth in the following
paragraph, the affirmative vote of the holders of 75% of the outstanding shares
of the Company entitled to vote on the applicable record date
 
                                       80
<PAGE>
is required for: (i) any merger or consolidation to which the Company, or any of
its subsidiaries, and an Interested Person are parties; (ii) any sale, lease,
exchange or other disposition by the Company, or any of its subsidiaries, of all
or substantially all of the Company's or its subsidiaries' assets to an
Interested Person; (iii) any purchase or other acquisition by the Company, or
any of its subsidiaries, of assets or stock of an Interested Person, the
aggregate purchase price of which exceeds $20,000,000; and (iv) any other
transaction with an Interested Person which requires the approval of the
stockholders of the Company under the Delaware Corporation Law, as in effect
from time to time.
 
    The provisions of the preceding paragraph are not applicable to any
transaction described therein if the transaction is approved by resolution of
the Board of Directors, provided that a majority of the members of the Board of
Directors voting for the approval of such transaction are duly elected and
acting members of the Board of Directors prior to the time that the person, firm
or corporation, or any group thereof, with whom such transaction is proposed,
became an Interested Person.
 
CERTAIN PROVISIONS OF CALIFORNIA LAW
 
    The Company is a corporation organized under the laws of Delaware and
generally the laws of the state of incorporation govern the corporate operations
of a corporation and the rights of its stockholders. Certain provisions of the
California Corporations Code may become applicable to a corporation incorporated
outside of California, however, if (i) the corporation transacts intrastate
business in California and the average of its California property, payroll and
sales factors (as defined in the California Revenue and Taxation Code) with
respect to it is more than 50% during its latest fiscal year, (ii) more than
one-half of its outstanding voting securities are held of record by persons
having addresses in California and (iii) the corporation is not otherwise
exempt. An exemption is provided if the corporation has outstanding securities
listed on the American Stock Exchange (a "Listed Corporation").
 
    The Company intends to apply to list its Common Stock on the American Stock
Exchange. However, no assurances can be given that the Company's application
will be granted. If granted, the Company would be exempt as a Listed
Corporation.
 
    Except as discussed herein, provisions of California law which could be
applicable to the Company if the Company meets these tests and is not exempt as
a listed company include, without limitation, those provisions relating to the
stockholders' right to cumulative votes in elections of directors (cumulative
voting is mandatory under California law), and the Company's ability to
indemnify its officers, directors and employees (which is more limited in
California than in Delaware). Notwithstanding the foregoing, a corporation may
provide for a classified board of directors, or eliminate cumulative voting, or
both if it is a Listed Corporation.
 
TRANSFER AGENT, REGISTRAR AND WARRANT AGENT
 
    The transfer agent and registrar for the Company's Common Stock and the
warrant agent for the Warrants is American Stock Transfer & Trust Company, New
York, New York.
 
                        SHARES ELIGIBLE FOR FUTURE SALE
 
    Upon completion of the Offering, the Company will have approximately
7,449,395 shares of Common Stock outstanding (7,899,395 shares if the
Underwriters' over-allotment option is exercised in full), as well as Warrants,
Representative's Warrants and other options and warrants for the purchase of up
to approximately 4,504,559 additional shares of Common Stock (5,954,559 shares
if the Underwriters' over-allotment option is exercised in full).
 
    Of the shares that will then be outstanding, the 3,000,000 shares sold in
the Offering (3,450,000 shares if the Underwriters' over-allotment option is
exercised in full) will be freely tradable without restriction under the
Securities Act, unless they are held by an "affiliate" of the Company, as that
term is defined in
 
                                       81
<PAGE>
Rule 144 under the Securities Act, in which case resales would be subject to
certain limitations and restrictions described below.
 
    The remaining 4,449,395 shares of Common Stock outstanding upon completion
of the Offering will be "restricted securities" as defined in Rule 144 and may
be sold in the public market only if registered under the Securities Act or sold
in accordance with an applicable exemption from registration, such as Rule 144.
Of these restricted shares, 2,597,083 shares (the "Rule 144(k) Shares") will be
eligible for resale without restriction under the Securities Act in compliance
with Rule 144(k) as described below, 1,025,039 shares (the "Rule 144 Shares")
will be eligible for resale subject to the other provisions of Rule 144
described below, and 827,273 shares (the "Non-Rule 144 Shares") will
subsequently become eligible for resale under Rule 144 upon expiration of their
respective one-year holding periods. However, all of the Rule 144 Shares and
624,000 of the Non-Rule 144 Shares will be subject to contractual lock-up
agreements between the holders of such shares and the Company or the
Underwriters. The lock-up agreements will prohibit the Company's officers,
directors and beneficial owners of 5% or more of the Common Stock from directly
or indirectly offering, selling or otherwise transferring a beneficial interest
in securities of the Company without the prior written consent of the Company
and the Representative for a period of twelve months after the Effective Date.
The Company has also agreed, with limited exceptions, not to sell or offer for
sale any of its securities without the consent of the Underwriters until twelve
months after the Effective Date.
 
    In general, under Rule 144 as currently in effect, a person (or persons
whose shares are aggregated) who has beneficially owned restricted shares for at
least one year is entitled to sell, within any three-month period, a number of
such shares that does not exceed the greater of (i) 1% of the then-outstanding
shares of Common Stock (approximately 74,494 shares immediately after the
Offering) and (ii) the average weekly trading volume during the four calendar
weeks preceding the sale. Sales under Rule 144 are also currently subject to
certain requirements as to the manner of sale, the filing of a notice of
proposed sale, and the availability of current public information about the
Company. Rule 144 also provides that affiliates who own securities that are not
restricted shares must nonetheless comply with the same restrictions applicable
thereunder to restricted shares, with the exception of the one-year holding
period requirement. A person who has not been an affiliate of the Company at any
time within three months prior to the sale and has beneficially owned the
restricted shares for at least two years is entitled to sell such shares under
Rule 144(k) without regard to the volume limitations or any of the other
requirements described above.
 
    Prior to the Offering, there has been no established public trading market
for the Company's Common Stock. See "Price Range of Common Stock and Dividend
Policy." Any sale of substantial amounts of Common Stock, or the perception that
such sales could occur, could adversely affect the prevailing market price for
the Common Stock and could impair the Company's future ability to raise capital
through an offering of its equity securities. See "Risk Factors--Shares Eligible
for Future Sale."

    The Underwriters named below (the "Underwriters"), for whom Security Capital
Trading, Inc., is acting as representative (in such capacity, the
"Representative"), have severally agreed, subject to the terms and conditions of
the Underwriting Agreement (the "Underwriting Agreement") to purchase from the
Company and the Company has agreed to sell to the Underwriters on a firm
commitment basis, the respective numbers of Shares and Warrants set forth
opposite their names:

    The Underwriters are committed to purchase all the Shares of Common Stock
and Warrants offered hereby, if any of such securities are purchased. The
Underwriting Agreement provides that the obligations of the several Underwriters
are subject to conditions precedent specified therein.
 
    The Company has been advised by the Representative that the Underwriters
propose initially to offer the Securities to the public at the initial public
offering prices set forth on the cover page of this Prospectus and to certain
dealers at such prices less concessions not in excess of $         per Share and
$         per Warrant. Such dealers may reallow a concession not in excess of
$         per Share and $         per Warrant to certain other dealers. After
the initial public offering, the offering prices, concessions and reallowances
to dealers may be changed by the Representative. No such change, however, shall
change the amount of proceeds to be received by the Company as set forth on the
cover page of this Prospectus.
 
    The Representative has informed the Company that it does not expect sales to
discretionary accounts by the Underwriters to exceed five percent of the
Securities offered hereby.
 
    The Company has agreed to indemnify the Underwriters against certain
liabilities, including liabilities under the Securities Act, or to contribute to
payments that the Underwriters may be required to make. The Company has been
advised that in the opinion of the Securities and Exchange Commission such
indemnification is against public policy as expressed in the Securities Act and
is, therefore, unenforceable. The Company has also agreed to pay to the
Representative a non-accountable expense allowance equal to 2.5% of the gross
proceeds derived from the sale of the Securities underwritten, of which $50,000
has been paid to date.
 
    The Company has granted to the Underwriters an over-allotment option,
exercisable during the forty-five (45) day period from the date of this
Prospectus, to purchase up to an additional 450,000 shares of Common Stock
and/or 450,000 Warrants at the initial public offering price per Share and
Warrant, respectively, offered hereby, less underwriting discounts and the
non-accountable expense allowance. Such option may be exercised only for the
purpose of covering over-allotments, if any, incurred in the sale of the
Securities offered hereby. To the extent such option is exercised in whole or in
part, each Underwriter will have a firm commitment, subject to certain
conditions, to purchase the number of the additional Securities proportionate to
its initial commitment.
 
    In connection with this Offering, the Company has agreed to sell to the
Representative, for nominal consideration, warrants (the "Representative's
Warrants") to purchase from the Company up to 300,000 shares of Common Stock
and/or 300,000 Warrants (the "Underlying Warrants"). The Representative's
Warrants are initially exercisable at a price of $7.20 per share of Common Stock
and $.12 per Warrant for a period of four (4) years, commencing at the beginning
of the second year after their issuance and sale and are restricted from sale,
transfer, assignment or hypothecation for a period of twelve (12) months from
the date hereof, except to officers of the Representative. The Representative's
Warrants provide for adjustment in the number of shares of Common Stock and
Warrants issuable upon the exercise thereof and in
 
                                       83
<PAGE>
the exercise price of the Representative's Warrants as a result of certain
events, including subdivisions and combinations of the Common Stock. The
Representative's Warrants grant to the holders thereof certain rights of
registration for the securities issuable upon exercise thereof. The Underlying
Warrants are initially exercisable at a price of $8.40 per share of Common Stock
for a period of four (4) years, commencing at the beginning of the second year
after their issuance and sale and otherwise have substantially the same terms
and provisions as the Warrants.
 
    In connection with this Offering, certain Underwriters and selling group
members and their respective affiliates may engage in transactions that
stabilize, maintain or otherwise affect the market prices of the Securities.
Such transactions may include stabilization transactions effected in accordance
with Rule 104 of Regulation M, pursuant to which such persons may bid for or
purchase the Common Stock and/or Warrants for the purpose of stabilizing their
respective market prices. The Underwriters also may create a short position for
the account of the Underwriters by selling more Securities in connection with
the Offering than they are committed to purchase from the Company, and in such
case may purchase Securities in the open market following completion of the
Offering to cover all or a portion of such short position. The Underwriters may
also cover all or a portion of such short position, up to 450,000 shares of
Common Stock and/or 450,000 Warrants, by exercising the over-allotment option
referred to above. In addition, the Representative may impose "penalty bids"
under contractual arrangements with the Underwriters whereby it may reclaim from
an Underwriter (or dealer participating in the Offering) for the account of
other Underwriters, the selling concession with respect to the Securities that
are distributed in the Offering but subsequently purchased for the account of
the Underwriters in the open market. Any of the transactions described in this
paragraph may result in the maintenance of the prices of the Securities at a
level above which might otherwise prevail in the open market. None of the
transactions described in this paragraph is required, and, if they are
undertaken, they may be discontinued at any time.
 
    Prior to this Offering, there has been no active trading market for the
Common Stock or the Warrants. Consequently, the initial public offering prices
of the Securities and the exercise price of the Warrants have been determined
arbitrarily by negotiations between the Company and the Representative and do
not necessarily bear any relationship to the Company's asset value, net worth,
or other established criteria of value. The factors considered in such
negotiations, in addition to prevailing market conditions, included the history
of and prospects for the industry in which the Company competes, an assessment
of the Company's management, the prospects of the Company, its capital structure
and the market for initial public offerings.
 
    Securities Capital Trading, Inc., the Representative, commenced operations
in June 1995. The Representative has co-managed and participated as an
underwriter in only two previous public offerings of securities. Accordingly,
the Representative has limited experience as a co-manager or underwriter of
public offerings of securities. In addition, the Representative is a relatively
small firm and no assurance can be given that the Representative will be able to
participate as a market maker of the Securities. No assurance can be given that
any broker-dealer will be a market maker in any of the Securities. See "Risk
Factors-- Lack of Experience of Representative."
 
                                 LEGAL MATTERS
 
    Certain legal matters with respect to the Common Stock offered hereby will
be passed upon for the Company by Miller & Holguin, Los Angeles, California.
Miller & Holguin owns 160,162 shares of the Company's outstanding Common Stock.
Certain legal matters in connection with the Offering will be passed upon for
the Underwriters by Hall Dickler Kent Friedman & Wood LLP, New York, New York.

Board of Directors
Prospect Medical Holdings, Inc.
 
    We have audited the consolidated balance sheet of Prospect Medical Holdings,
Inc., as of September 30, 1997, and the related consolidated statements of
operations, shareholders' equity and cash flows for the year then ended. These
financial statements are the responsibility of the Company's management. Our
responsibility is to express an opinion on these consolidated financial
statements based on our audit. The financial statements of Prospect Medical

other auditors whose report dated November 20, 1996, expressed an unqualified
opinion on those statements.
 
    We conducted our audit in accordance with generally accepted auditing
standards. Those standards require that we plan and perform the audit to obtain
reasonable assurance about whether the financial statements are free of material
misstatement. An audit includes examining, on a test basis, evidence supporting
the amounts and disclosures in the financial statements. An audit also includes
assessing the accounting principles used and significant estimates made by
management, as well as evaluating the overall financial statement presentation.
We believe that our audit provides a reasonable basis for our opinion.
 
    In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the consolidated financial position of
Prospect Medical Holdings, Inc., at September 30, 1997, and the consolidated
results of their operations and their cash flows for the year then ended, in
conformity with generally accepted accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
 
                               SEPTEMBER 30, 1997
 
1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES
 
BUSINESS AND BASIS OF PRESENTATION
 
    Prospect Medical Holdings, Inc., a Delaware corporation (the Company or
Prospect), was incorporated on May 12, 1993. Prospect is a health care
management services organization which develops integrated delivery systems, and
provides medical management systems and services to affiliated and unaffiliated
medical organizations. The affiliated medical organizations employ and/or
contract with physicians and professional medical corporations, and contract
with managed care payors.
 
    Prospect currently manages the provision of prepaid health care services for
their affiliated medical organizations in Southern California. The Network
consists of the following related medical organizations as of September 30,
1997:
 
    Prospect Medical Group, Inc. (PMG)
 
    Sierra Primary Care Medical Group, a Medical Corporation (SPCMG)
 
    Santa Ana-Tustin Physicians Group, Inc. (SATPG)
 
    Each of the medical organizations listed above is owned by a nominee
physician shareholder who is also an employee, member of management and a
shareholder of Prospect. Under the nominee shareholder agreements, Prospect has
the unilateral right to establish or effect change of the nominee, at will, and
without consent of the nominee on an unlimited basis and at nominal cost
throughout the term of the Agreements described below. Effective June 5, 1996,
for Prospect Medical Group, Inc., and upon acquisition, the remaining network
affiliates (the Affiliates), each entered into a long-term management agreement
(the Agreements) whereby the Affiliates have agreed to pay a management fee to
Prospect Medical Systems or Sierra Medical Management, Inc., as applicable (each
of which is a wholly owned subsidiary of Prospect). The fee is based on a
percentage of revenues the Affiliate is entitled to receive for the performance
of medical services by the Affiliate's employees and independent contractor
physicians and physician extenders, and for all other services performed by the
Affiliates. This includes medical capitation, all sums earned from participation
in any risk pools and all fee revenue earned. The Agreements have initial terms
of 30 years renewable for successive 10-year periods thereafter unless
terminated by either party for cause. In return for payment of the management
fee, Prospect has agreed to provide financial management, information systems,
marketing, advertising and public relations, risk management, and administrative
support for utilization review and quality of care. The Company has exclusive
decision making authority with respect to the establishment and preparation of
operating and capital budgets and the establishment of policies and procedures
for the Affiliates and makes recommendations for the development of guidelines
for selection and hiring of health care professionals, compensation payable to
such personnel, scope of services to be provided, patient acceptance policies,
pricing of services, and contract negotiation and execution. At its cost,
Prospect has assumed the obligations for all facilities, medical and nonmedical
supplies for its affiliated medical groups, and employment of nonphysician
personnel. All remaining funds are remitted to the Affiliate, from which the
Affiliate pays for the cost of all medical services. The management fee earned
by Prospect fluctuates based on the profitability of the affiliated medical
groups as Prospect retains a 50% residual interest in the profits of the groups,
including proceeds from the sale of assets or the merger or other business
combination of the Affiliate.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    The Agreements are not terminable by the Affiliates except in the case of
gross negligence, fraud or other illegal acts of Prospect, or bankruptcy of the
Company. Through the Company's nominee shareholder, Prospect has exclusive
authority over all decision making related to the ongoing major or central
operations of the physician practices, including compensation of the physicians
and physician extenders. The Company, however, does not engage in the practice
of medicine.
 
    Further, Prospect's rights under the Agreements are unilaterally salable or
transferable. Based on the provisions of the Agreements, Prospect has determined
that it has a controlling financial interest in the Affiliates and consequently
consolidates the revenue and expenses of the Affiliates from the date of
execution of the agreements. All significant inter-entity balances have been
eliminated in consolidation.
 
    As of September 30, 1997, Prospect managed health care services to
approximately 62,000 commercial, 7,300 senior and 6,000 Medicaid enrollees under
contracts with various health plans.
 
REVERSE ACQUISITION
 
    In July 1996, Prospect changed its name from Med-Search, Inc. (Med-Search)
in connection with an Agreement and Plan of Reorganization (the Merger
Agreement). Under the Merger Agreement, Med-Search Acquisition Corporation, a
wholly owned subsidiary of Med-Search, a physician practice management company,
was merged with and into Prospect Medical Systems (PMS), with PMS being the
surviving corporation. The transaction has been accounted for as a reverse
acquisition as the shareholders of PMS became the majority shareholders of
Med-Search after the combination of the companies. Therefore, the assets
acquired and liabilities assumed of Med-Search were recorded at fair value as of
the acquisition date. Concurrent with the merger, Prospect completed a private
placement offering raising $2,500,000 in cash ($2,359,143 net of costs) in
exchange for 2,002,023 shares of Prospect's common stock. Med-Search
shareholders were issued 763,033 shares of Prospect common stock in connection
with the merger and, based on the share price of the private placement, were
valued at $1.25 per share or $953,791.
 
    In addition to the issuance of shares, Prospect incurred costs totaling
$489,784 in attorneys' fees and other costs, and incurred $526,327 of costs to
settle litigation and costs related to former shareholders/ officers of
Med-Search. The excess of costs over the fair value of Med-Search's net assets
totaled $2,196,612, and has been reflected in goodwill and other intangible
assets as of September 30, 1996.
 
MEDICAL REVENUES AND COST RECOGNITION
 
    Operating revenue of the Company consists primarily of fees for medical
services provided by the Affiliates under capitated contracts with various
managed care payors including health maintenance organizations (HMOs) or under
fee-for-service type arrangements. During the year ended September 30, 1997, the
Company received approximately 33%, 16% and 11% of its total revenue from
contracts with three HMOs. Capitation revenue under HMO contracts is prepaid
monthly to the Affiliates (and assigned to Prospect) based on the number of
enrollees electing any one of the Affiliates as their health care provider. HMO
contracts also include provisions to share in the risk for hospitalization
whereby Prospect can earn additional incentive revenue or incur penalties based
upon the utilization of hospital services. Estimated shared-risk amounts
receivable from the HMOs are recorded based upon estimated hospital utilization
and estimated associated costs incurred by assigned HMO enrollees, compared to
budgeted costs. Differences between actual contract settlements and estimated
receivables relating to HMO risk-sharing arrangements are recorded in the year
of final settlement.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    In connection with providing services to HMO enrollees, the Affiliates are
responsible for the medical services their affiliated physicians provide to
assigned HMO enrollees. The cost of health services is recognized in the period
in which it is provided and includes an estimate of the cost of services which
have been incurred but not yet reported. The estimate for accrued medical costs
is based on actuarial projections of costs using historical studies of claims
paid. Estimates are continually monitored and reviewed and, as settlements are
made or estimates adjusted, differences are reflected in current operations.
 
    The Affiliates participate in reinsurance protection programs which limit
the amount of risk they ultimately bear by providing reimbursement payments once
medical services provided to an individual enrollee exceed an agreed-upon
deductible amount. Estimates of reinsurance recoveries are included in accounts
receivable in the accompanying financial statements and, in the opinion of
management, adjustments, if any, would not have a material effect on the
consolidated financial position of the Company.
 
PROPERTY, IMPROVEMENTS AND EQUIPMENT
 
    Property, improvements and equipment are stated on the basis of cost.
Depreciation of equipment is provided using the straight-line method over the
estimated useful lives of the assets, and amortization of leasehold improvements
is provided using the straight-line basis over the shorter of the lease period
or the estimated useful lives of the leasehold improvements. Capitalized lease
obligations are amortized over the life of the lease. Lease amortization is
included in depreciation expense.
 
GOODWILL AND OTHER INTANGIBLE ASSETS
 
    Goodwill and other intangible assets totaling $16,208,343 arose as the
result of the acquisition of Sierra Medical Management, Inc., Sierra Primary
Care Medical Group and Santa Ana-Tustin Physicians Group, Inc. Other intangible
assets consist of the fair value of acquired HMO contracts, covenants not to
compete and workforce in place. Goodwill represents the excess of the
consideration paid and liabilities assumed over the fair value of the assets
acquired including identifiable intangible assets. The fair values of these
assets have been preliminarily allocated to such assets. Such acquisitions are
discussed in Note 2 following.
 
    Goodwill and other intangible assets have been recorded at cost and are
being amortized on the straight-line method over an average life of 20 years
based on a preliminary allocation of the estimated fair values of the net assets
acquired. Accumulated amortization was $49,292 at September 30, 1997.
 
    The Company periodically evaluates the realization of these assets and they
are written down to estimated fair value when appropriate. During fiscal 1997,
Prospect terminated the HMO contract supporting the network acquired in the
Med-Search combination discussed above. Consequently, all intangible assets
acquired from Med-Search were considered impaired and of no continuing value. An
impairment loss totaling $2,196,612 has been recorded in fiscal 1997 related to
this circumstance.
 
MEDICAL MALPRACTICE LIABILITY INSURANCE
 
    Certain of the Affiliates maintain claims-made basis medical malpractice
insurance coverage of up to $2,000,000 per incident and $4,000,000 in the
aggregate on an annual basis. Claims-made coverage covers only those claims
reported during the policy period. An estimate of losses, if any, for incurred

unreported claims is recorded based upon historical experience. In 1997,
Prospect caused its affiliates to renew their existing policies and expects to
be able to continue to obtain coverage in future years. Further, it has been the
Company's experience that substantially all claims are reported within a year of
the incident date.
 
    The individual physicians who contract with the Affiliates carry their own
medical malpractice insurance.
 
EARNINGS (LOSS) PER SHARE
 
    Effective December 15, 1997, the Company was required to adopt Statement of
Financial Accounting Standards (SFAS) No. 128 "Earnings per Share." SFAS No. 128
requires the presentation of "basic earnings per share" (which excludes
dilution) and "diluted earnings per share." All earnings per share calculations
presented in the financial statements have been presented in accordance with
SFAS No. 128.
 
    Basic earnings (loss) per share is computed by dividing net income (loss) by
the weighted average number of common shares outstanding. Diluted earnings
(loss) per share is computed by dividing net income (loss) by the weighted
average number of common shares outstanding, after giving effect to potentially
dilutive shares computed using the treasury stock method. Such shares are
excluded if determined to be anti-dilutive. Common stock issued at below
estimated fair value on the issuance date is included in weighted average number
of common shares as if such shares have been outstanding for all periods
presented.

(2) Stock options and warrants are excluded from the calculation of diluted loss
    per share for the fiscal year ended September 30, 1997, and the nine months
    ended June 30, 1997, because the inclusion of stock options and warrants
    would have an anti-dilutive effect.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
 
1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
 
STOCK OPTIONS
 
    In October 1995, SFAS No. 123 "Accounting for Stock-Based Compensation" was
issued which provides an alternative to Accounting Principles Board (APB)
Opinion 25 "Accounting for Stock Issued to Employees." SFAS No. 123 encourages,
but does not require, that compensation expense for grants of stock, stock
options and other equity instruments to employees be based on the fair value of
such instrument. The statement also allows companies to continue to measure
compensation expense using the intrinsic value method prescribed by APB Opinion
No. 25. The Company has elected to continue using the intrinsic value based
method.
 
    With respect to stock options granted at an exercise price which is less
than the fair market value on the date of grant, the difference between the
option exercise price and market value at date of grant is charged to operations
over the period the options vest. Income tax benefits attributable to stock
options are credited to additional paid-in capital when exercised.
 
CASH AND CASH EQUIVALENTS
 
    Cash equivalents are considered to be all liquid investments with a maturity
of three months or less when purchased.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The financial instruments reported in the accompanying consolidated balance
sheets consist primarily of cash and cash equivalents, accounts receivable,
notes payable and capital lease obligations and all other liabilities. The
carrying amounts of current assets and liabilities approximate their fair value
due to the relatively short period of time between the origination of the
instruments and their expected realization.
 
    The carrying amounts of notes payable and capital lease obligations
approximate fair value since the outstanding debt relates primarily to revolving
bank loans which bear interest at the prime rate plus applicable margin. The
carrying amounts of the remaining notes payable approximate their fair value as
interest rates used in valuing these instruments approximate interest rates
currently available to the Company.
 
CONCENTRATIONS OF CREDIT RISK
 
    Financial instruments which potentially subject the Company to
concentrations of credit risk consist of shared-risk and stop-loss receivables.
The Company's credit risk with respect to shared-risk and stop-loss receivables
is limited since amounts are generally due from large HMOs.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets, liabilities, revenues
and expenses at the date and for the periods that the financial statements are
prepared. Actual results could differ from those estimates.

    At September 30, 1997, the Company has a revolving credit agreement with a
bank for $10,000,000 with interest at the bank's prime rate, plus an applicable
margin (ranging from .50% to 1.50%). As of February 6, 1998, the Company
increased the principal available under the revolving credit agreement to
$12,500,000. Interest is payable monthly on a 360-day basis. The line expires
July 3, 1999. The line is collateralized by the stock of Prospect's subsidiaries
and the Company's accounts receivable, inventory and unencumbered equipment. The
line is also subject to financial covenants, including maintaining certain
financial ratios. As of September 30, 1997, the Company did not meet certain
financial ratios. The bank has waived compliance with these ratios as of
September 30, 1997, and December 31, 1997, made the waivers effective
retroactive to September 1, 1997, and has revised the ratios for periods
thereafter (see Note 8). The Company expects to be able to meet the revised
ratios in the future. The line has a facility fee of 0.5% per year on the unused
balance of the line. In connection with the revolving credit agreement, Prospect
granted a warrant to the bank to purchase 192,725 (132,375 as of September 30,
1997), shares of common stock at $5.00 per share (see Note 5). The fair value of
notes payable approximates the carrying value due either to the short-term
nature of such notes or the fact that the notes bear interest at rates currently
available to the Company under similar terms.
 
    Interest paid totaled $36,850, $36,313, and $151,654 in 1995, 1996 and 1997,
respectively.
 
    Payments under long-term notes as of September 30, 1997, follow:

</TABLE>
 
    The Company has elected to follow APB Opinion No. 25 and related
interpretations in accounting for its stock options because, as discussed below,
the alternative fair value accounting provided for under SFAS No. 123 requires
use of option valuation models that were not developed for use in valuing stock
options. Under APB No. 25, because the exercise price of the Company's stock
options equals or exceeds the market price of the underlying stock on the date
of grant, no compensation expense is recognized.
 
    Pro forma information regarding net loss and loss per share is required by
SFAS No. 123, and has been determined as if the Company had accounted for its
stock options under the fair value method of that Statement. The fair value of
these options was estimated at the date of grant using a Minimum Value option
pricing model with the following weighted average assumptions for 1997: expected
market price of the Company's common stock at $1.25 for 477,119 option shares
and $2 for 35,000 option shares on the respective dates of grant, a weighted
average expected life of the options of five years, risk-free interest rate of
6%, and dividend yield of 0%.
 
    The Minimum Value option valuation model was developed for use in estimating
the fair value of traded options which have no vesting restrictions and are
fully transferable. In addition, option valuation models require the input of
highly subjective assumptions including the expected stock price volatility.
Because the Company's stock options have characteristics significantly different
from those of traded options, and because changes in the subjective input
assumptions can materially affect the fair value estimate, in management's
opinion, the existing models do not necessarily provide a reliable single
measure of the fair value of its stock options.

    Pro forma disclosures required by SFAS No. 123 include the effects of all
stock option awards granted by the Company in fiscal 1997. During the initial
phase-in period, the effects of applying this Statement for generating pro forma
disclosures are not likely to be representative of the effects on pro forma net
income or loss for future years, for example, because options may vest over
several years and additional awards generally are made for each year. For
purposes of pro forma disclosures, the estimated fair value of the options is
amortized to expense over the options' vesting period. The Company's pro forma
information is as follows for the year ended September 30, 1997.

WARRANTS
 
    As of July 31, 1996, warrants to purchase 13,635 shares of the Company's
common stock at $1.375 per share were issued to finders in connection with the
Med-Search merger. The warrants are exercisable at the date of grant and expire
in July 2001. In connection with the $10 million revolving line of credit,
Prospect granted a warrant in July 1997 to the bank to purchase 192,725 (132,375
at September 30, 1997), shares of common stock at $5.00 per share. The warrants
are immediately exercisable. The warrant to purchase 132,375 common shares
expires in July 2004 and the warrant to purchase 60,350 common shares expires in
February 2005.

REGULATORY MATTERS
 
    Laws and regulations governing the Medicare program are complex and subject
to interpretation. Prospect and its affiliates believe that they are in
compliance with all applicable laws and regulations and are not aware of any
pending or threatened investigations involving allegations of potential
wrongdoing.

While no such regulatory inquiries have been made, compliance with such laws and
regulations can be subject to future government review and interpretation as
well as significant regulatory action including fines, penalties, and exclusion
from the Medicare and Medicaid programs.
 
LITIGATION
 
    Prospect is involved in various legal proceedings in the ordinary course of
business. Management believes that the ultimate resolution of such legal
proceedings will not have a material adverse effect on the financial position
and results of operations of the Company.
 
YEAR 2000 - UNAUDITED
 
    The Company has formed a Year 2000 project team which has completed an
inventory of all systems and programs, categorized as to importance, which could
be affected by the Year 2000 date change.
 
    The Company has recently purchased a sophisticated management information
system for approximately $1,100,000 for its managed care segment which accounts
for 89% of the Company's revenue. The purchase agreement requires the vendor to
install a Year 2000 module to handle the Year 2000 issue at no additional cost.
The Company expects to install this module in February 1999 and complete testing
within 90 days. The billing and collection system currently leased by the
Company for its fee-for-service segment, which accounts for less than 7.5% of
its revenues, is not Year 2000 compliant. A Year 2000 software upgrade is
scheduled in October 1998 at no additional cost from the vendor with testing to
be completed within 30 days. In addition, the Company has obtained a Year 2000
software upgrade for its financial and general ledger systems at negligible cost
to be installed and tested by October 15, 1998. The Company tested and
determined all medical equipment to be Year 2000 compliant. Management believes
that its personal computers which utilize the Windows NT operating system are
capable of handling the Year 2000 date change. In addition to replacing or
modifying its programs and systems, the Company has also contacted all hospitals
and health plans with which it transacts business and has been provided
assurance that they will be Year 2000 compliant by March 1999.
 
    Since no assurance can be provided that the Year 2000 issue will be
successfully resolved, the Company's project team will complete a contingency
plan by March 31, 1999 to address potential problems in the event the Company's
systems or programs or principal business partners fail to be Year 2000
compliant. Costs of modifying the software to remediate Year 2000 problems are
charged to expense as incurred.
 
7. SUBSEQUENT EVENTS
 
COMPLETED AND PENDING ACQUISITIONS
 
    In October 1997, Pegasus Medical Group Inc., an affiliate of Prospect,
purchased substantially all the assets of AV Western Medical Group, Inc. The
acquisition price of $700,000 was allocated to goodwill.
 
    On December 17, 1997, the Company executed a binding commitment letter to
purchase certain assets of Antelope Valley Medical Group, Inc. for consideration
totaling $500,000 in cash and $500,000 in a short-term promissory note bearing
interest at 8% per year and 200,000 shares of the Company's common stock. The
acquisition was completed effective as of June 1, 1998.

SHAREHOLDER SETTLEMENT
 
    The Company maintains an administrative service agreement with Yorba Linda
Medical Group (YLMG) under which the Company provides administrative and
operational services such as contract management, utilization review, case
management, claims processing and payment and quality assurance. Pursuant to the
agreement, YLMG and the professional physician groups have agreed to pay to the
Company a management fee for its services. A majority of the YLMG shareholders
are also shareholders of Prospect.
 
    On July 1, 1998, the Company entered into a settlement agreement with a
group of YLMG physicians whereas the physicians surrendered 1,126,323 shares of
the Company's common stock previously issued to them in return for a release
from noncompetition and nondiversion provisions contained in certain agreements.
Prospect estimates a loss of approximately 13,000 enrollees who were served by
these physicians. Revenues, medical costs and operating expenses related to
these enrollees in fiscal 1997 were estimated at approximately $8,278,000,
$5,866,000 and $891,000, respectively.
 
8. NOTE TO UNAUDITED INTERIM FINANCIAL STATEMENTS
 
    The unaudited financial information for the nine-month periods ended June
30, 1997, and June 30, 1998, has been prepared in accordance with generally
accepted accounting principles for interim financial information. In the opinion
of management, all adjustments considered necessary for a fair presentation,
which consist solely of normal recurring adjustments, have been included. The
interim information should be read in conjunction with the financial statements
for the years ended September 30, 1995, 1996, and 1997. Operating results for
interim periods are not necessarily indicative of the results which may be
expected for the entire year.
 
    The Company was not in compliance with certain financial covenants at March
31, 1998 and June 30, 1998, respectively. The Company has received waivers from
its lender with respect to compliance with those covenants as of those dates.
 
    Effective July 1, 1998, a settlement agreement was entered into among the
Company, Prospect Medical Group, Yorba Linda Medical Group, and the
physician-shareholders of Yorba Linda Medical Group (the "Yorba Linda Settlement
Agreement"). On July 31, 1998, certain parties related to the Company filed a
motion to enforce the Yorba Linda Settlement Agreement (the "Company's Motion"),
in a pending action entitled DENICOLA V. MCGINTY, Orange County Superior Court
Case No. 795018. The opposing parties, consisting of Yorba Linda Medical Group
and the members of its Board of Directors, responded by filing a cross-motion
for enforcement (the "YLMG Motion"). On or about August 14, 1998, prior to a
ruling on either motion, Yorba Linda Medical Group and its remaining
physician-shareholders filed a lawsuit against the Company, Prospect Medical
Group, Prospect Medical Systems, Dr. DeNicola and certain other individual
physicians seeking damages and injunctive relief based upon allegations of
breach of contract, fraud and certain related claims with respect to the Yorba
Linda Settlement Agreement (MCGINTY V. PROSPECT MEDICAL GROUP, ET AL., Orange
County Superior Court Case No. 798208 (the "MCGINTY Lawsuit")). The court on
September 1, 1998 granted the material portions of the Company's Motion to
enforce the Yorba Linda Settlement Agreement, denied the material portions of
the YLMG Motion, and ordered the parties to mediate the remaining unresolved
issues. The Company believes the MCGINTY Lawsuit is without merit and is barred
by the Yorba Linda Settlement Agreement.

1. BACKGROUND AND ORGANIZATION
 
    Antelope Valley Medical Group, Inc. (AVMG or the Group) was incorporated as
a not-for-profit organization in 1985 as Antelope Valley Group (AVG). In 1987,
AVG reorganized as a mutual benefit organization. In June 1995, AVG became a
for-profit corporation through a statutory merger with a for-profit entity and
was renamed Antelope Valley Medical Group, Inc. The Group is a primary care
physicians group which services patients in the communities of Lancaster and
Palmdale, California. AVMG is organized as a professional corporation under the
Internal Revenue Code.
 
    In June 1996, the outstanding common stock of the Group was purchased by
PrimeCare Medical Group of Antelope Valley, Inc. (PCAV), which is solely owned
by the controlling physician shareholder of PrimeCare International, Inc. (PCI).
Concurrent with the acquisition, AVMG entered into a management services
agreement (MSA) with PCI.
 
    The MSA has an initial term of 30 years renewable for successive 15-year
periods unless terminated by either party for cause. Under the agreement, PCI
provides centralized non-medical administrative and operational services such as
accounting, information systems, quality assurance, billing and collections,
claims processing and payment, utilization and review, contract management,
provider and member services, marketing, financial reporting, and case
management. As compensation for services rendered, PCI receives a management fee
equal to the Group's capitation and incentive program revenues less provider
expenses.
 
    At December 31, 1997, AVMG provides health services to approximately 11,100
commercial and 1,000 Medicare enrollees under contracts with various health
plans.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
PUSH-DOWN ACCOUNTING
 
    As discussed further in Note 6, all of the common stock of AVMG was acquired
by PCAV as of June 30, 1996, for total consideration of $3 million including $1
million in cash and a non-interest bearing note for $2 million. The purchase
consideration and resulting goodwill has been recorded on the books of AVMG. The
push-down entries resulted in an increase in shareholder's equity of $1,777,000,
notes payable of $2 million, $800,000 liability associated with an employee
termination and goodwill of $4,577,000 as of the acquisition date. In January
1997, the $2 million note was paid to the former shareholders and recorded by
PCI as a capital contribution to AVMG in the accompanying financial statements.
 
    The financial statements reflect the combined operating results of the Group
as well as non-medical expenses incurred by PCI in the management of the Group's
operations (see Note 5).
 
MEDICAL REVENUE AND COST RECOGNITION
 
    Net patient service revenue consists primarily of fees for medical services
provided by the Group under capitated contracts with health maintenance
organizations (HMOs). Capitation revenue is prepaid monthly to the Group based
on the number of enrollees electing the Group as their health care provider. In
1997, four contracts accounted for 63% of the Group's capitated enrollees and
68% of its revenue. These contracts accounted for 74% of the Group's capitated
enrollees and 79% of its revenue in 1996.
 
    HMO contracts include provisions to share in the risk for hospitalization
whereby the Company can earn additional incentive revenue or incur penalties
based upon the utilization of hospital services. Shared-

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
risk amounts receivable from the HMOs or hospitals are recorded based upon
estimated hospital utilization and associated costs incurred by assigned HMO
enrollees, compared to budgeted costs. Differences between actual contract
settlements and estimated receivables relating to HMO risk-sharing arrangements
are recorded in the year of final settlement. In 1997 and 1996, the Group
recorded shared-risk revenue from HMOs and unaffiliated hospitals totaling
$99,000 and $155,000, respectively.
 
    Included in net patient service revenue in 1997 was net institutional
revenue of $317,000, relating to Desert Valley Hospital (DVH), an affiliated
medical facility owned by PCI. The institutional revenue represents capitation
payments received by DVH relating to the Group's enrollees less medical expenses
for institutional services rendered. Such net revenues are allocated to the
Group under an intercompany risk sharing agreement.
 
    In connection with providing services to HMO enrollees, the Group is
responsible for all covered medical services provided to assigned HMO enrollees.
The cost of medical services is recognized in the period in which it is provided
and includes an estimate of the cost of services which have been incurred but
not yet reported. The estimate for accrued medical costs is based on actuarial
projections of costs using historical studies of claims payments. Estimates are
continually monitored and reviewed and, as settlements are made or estimates
adjusted, differences are reflected in current operations.
 
    The Group participates in reinsurance protection programs which limit the
amount of risk it ultimately bears by providing reimbursement payments once
medical services provided to an individual enrollee exceed an agreed-upon
amount. Estimates of reinsurance recoveries are included in accounts receivable
and are reflected as a reduction of medical provider expense in the accompanying
financial statements.
 
CASH AND CASH EQUIVALENTS
 
    The Company considers all highly liquid investments with a maturity of three
months or less when purchased to be cash equivalents.

PROPERTY AND EQUIPMENT
 
    Property and equipment are stated at cost, and are depreciated using the
straight-line method over the useful lives of the assets which range from five
to seven years. Leasehold improvements are amortized using the straight-line
method over the shorter of the lease period or the estimated useful lives of the
leasehold improvements.

2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
MEDICAL MALPRACTICE LIABILITY INSURANCE
 
    The Group purchases claims-made basis professional liability coverage of up
to $1,000,000 per incident and $3,000,000 in the aggregate on an annual basis,
with a $25,000 deductible per case. Claims-made coverage covers only those
claims reported during the policy period. The recorded liability for claim
losses not covered by insurance, including losses incurred but not reported, is
estimated by an independent actuary based on the Group's claims experience using
a discount rate of 9% for both 1997 and 1996. There is no assurance that the
amount accrued will be adequate to cover actual claims settled.
 
GOODWILL
 
    Goodwill totaling $5,074,000 arose as the result of the acquisition of the
Group by PCAV. The amount represents the excess of the consideration paid and
liabilities assumed over the fair value of the assets acquired. Included in
total goodwill was an adjustment in 1997 of $497,000 to reflect the resolution
of an acquisition contingency which was primarily related to the resolution of
litigation arising from the Group's acquisition (see Note 6). Goodwill is being
amortized over 15 years.
 
    At each reporting period, management reviews the carrying value of goodwill
to determine if facts and circumstances exist which would suggest that goodwill
may be impaired or that the amortization period needs to be modified. Among the
factors considered in making the evaluation are changes in the payor or
physician contracts, local market developments, changes in regulations, national
health care trends, changes in third-party payment patterns and other factors.
In December 1997, PCI adopted a formal plan to exit the Lancaster market and
subsequently entered into an agreement in June 1998 to sell certain assets to
Prospect Medical Holdings, Inc. (Prospect--see Note 7).
 
    The sale of AVMG was based on PCI's assessment that it could not operate
AVMG profitably. Consequently, as a result of these factors, PCI determined that
the goodwill of AVMG was impaired and a write-down was necessary. Since PCI
entered into an agreement with Prospect to sell AVMG's management services
agreement and physician contracts of AVMG, PCI has determined that the sale
price represents the fair value of AVMG's goodwill as of December 31, 1997.
Therefore, an impairment adjustment of $3,168,000 was recorded as of December
31, 1997, and has been reflected in the accompanying statements of operations.
Amortization expense totaled $343,000 and $163,000 for 1997 and 1996,
respectively. Accumulated amortization, exclusive of the impairment charge, was
$506,000 and $163,000 at December 31, 1997 and 1996, respectively.
 
FAIR VALUE OF FINANCIAL INSTRUMENTS
 
    The carrying amounts of financial instruments reported in the accompanying
balance sheets (consisting primarily of cash and cash equivalents, accounts
receivable, and all liabilities) approximate their fair value due to the
relatively short period of time between the origination of the instruments and
their expected realization.
 
CONCENTRATION OF CREDIT RISK
 
    Financial instruments which potentially subject AVMG to concentrations of
credit risk consist primarily of cash and cash equivalents, accounts receivable
shared risk and reinsurance receivable. Concentration of credit risk with
respect to accounts receivable is limited, due to the large number of

payors comprising AVMG's customer base. Concentration of credit risk with
respect to shared risk and reinsurance receivable is limited since amounts are
generally due from large HMOs.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities as of the date of the financial
statements. Estimates also affect the reported amounts of revenues and expenses
during the reporting period. Estimates made by the Group relate primarily to
valuation of receivables and deferred tax assets, recoverability of intangibles,
accrued medical claims and medical malpractice liability. Actual results could
differ from these estimates.

</TABLE>
 
    Depreciation expense totaled $21,000 and $19,000 for 1997 and 1996,
respectively. In 1997, the Group recorded a charge of $57,000 to write off the
net carrying value of its property and equipment due to impairment of such
assets. The amount is included in depreciation and amortization expense.
 
4. INCOME TAXES
 
    The Group accounts for income taxes using the liability method as required
by Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" (SFAS No. 109). SFAS No. 109 is an asset and liability method which
requires the recognition of deferred tax assets and liabilities for the expected
future tax consequences of events that have been recognized in the Group's
financial statements or tax returns. Deferred income taxes reflect the net tax
effects of the temporary differences between the carrying amounts of assets and
liabilities for financial reporting purposes and the amounts used for income tax
return purposes. Deferred income taxes may also be recognized for operating
losses incurred that will be available to offset future federal and state
taxable income. In estimating future tax consequences, SFAS No. 109 generally
considers all expected future events other than enactments of changes in the tax
law or rates.
 
    The Group did not record a provision for income taxes for the years ended
December 31, 1997 and 1996, due to operating losses incurred.

    At December 31, 1997, the Group has net operating losses (NOLs) for income
tax purposes of approximately $917,000. The federal and state carryforwards,
unless utilized, will expire at various dates through 2011. The Tax Reform Act
of 1986 includes provisions which may limit the net operating loss carryforwards
available for use in any given year if certain events, including changes in
stock ownership could occur. Management believes that a portion of the NOLs may
be subject to an annual limitation under the provisions of Section 382 of the
Internal Revenue Code and may not be available during the 15-year carryforward
period. As such, a valuation allowance is provided for all deferred tax assets.
Benefits of deferred tax assets will be recognized when realized. Taxes paid in
1997 and 1996 were not significant.
 
5. RELATED PARTY TRANSACTIONS
 
ACQUISITION DEBT
 
    In June 1996, PCAV acquired all of the outstanding common stock of AVMG for
$3 million. $1 million was paid upon closing and recorded as paid in capital at
December 31, 1996. The remaining $2 million in a non-interest bearing note was
paid in January 1997. Prior to the acquisition, AVMG made distributions of cash
and other assets to the shareholders totaling $1.3 million. $1 million was
distributed

5. RELATED PARTY TRANSACTIONS (CONTINUED)
prior to closing and the remaining $300,000 was held pending the outcome of the
Group's litigation with a former officer (see Note 6). $150,000 was paid in
October 1997, and the remaining $150,000 was canceled due to the adverse outcome
of such legal matter. Total amounts due to former shareholders at December 31,
1996, of $2,300,000 were included in current liabilities in the accompanying
balance sheet. All amounts due were paid or canceled as of December 31, 1997.
 
MANAGEMENT COST
 
    PCI incurs certain expenses for the provision of management services to the
Group. Pursuant to the MSA, these costs are not separately reimbursable and are
included in the management fee. As discussed in Note 1, manager costs are
included in the accompanying financial statements to reflect the operating
results of the Group on a stand-alone basis. Direct expenses are recorded as
non-medical operating costs and general expenses of PCI allocable to the Group
are included in purchased services in the statements of operations. Total direct
and allocable expenses of PCI (excluding depreciation and amortization), were
$873,000 for 1997 and $448,000 for the six-month period from the acquisition
date to December 31, 1996. Payables to PCI for costs incurred in the amount of
$634,000 and $293,000 are included in due to affiliates (non-current) at
December 31, 1997 and 1996, respectively. Management fees computed in accordance
with the MSA were $186,000 and $587,000 for 1997 and the six months ended
December 31, 1996, respectively.
 
FULL RISK INCOME
 
    AVMG shares certain institutional revenue with Desert Valley Hospital (DVH),
a wholly owned subsidiary of PCI. Under an intercompany agreement, capitation
revenue received by DVH attributable to the Group's enrollees, net of the
related cost of institutional services, is allocated to the Group. Net revenues
totaled $317,000 in 1997, all of which were outstanding at year end. No amounts
were allocated to the Group in 1996.
 
OTHER
 
    Due to/from affiliates included in current assets (liabilities) arise from
the ordinary course of business and relates primarily to cash transfers between
the Group and PCI as the Group is included in PCI's centralized cash management
system.
 
6. COMMITMENTS AND CONTINGENCIES
 
LEASES
 
    The Company leases certain office space and equipment under operating leases
which expire through 1998. Minimum rental payments required in 1998 under the
operating leases that have initial or remaining noncancelable lease terms in
excess of one year at December 31, 1997, totaled $43,000. Rental expense for
1997 and 1996 was $40,000 and $71,000, respectively.
 
LITIGATION
 
    In June 1996, the Group terminated a former officer upon acquisition by PCAV
and recorded a liability of $800,000 for certain obligations pursuant to the
officer's employment agreement, although PCI had disputed its obligation to pay
such amount. This amount was included in goodwill recorded upon the

acquisition of the Group by PCI. In February 1998, the dispute was settled and
the Group received an adverse ruling totaling $1,112,000 in binding arbitration.
The award in excess of the amount accrued was recorded as an increase to
goodwill in 1997. Outstanding amounts due to the former officer included in
other current liabilities were $398,000, $1,112,000, and $800,000 at March 31,
1998, December 31, 1997 and December 31, 1996, respectively.
 
ASSETS PLEDGED
 
    In May 1997, PCI obtained a $75 million senior secured credit facility from
a commercial bank. At December 31, 1997, $55 million principal amount was
outstanding under this facility. To secure this facility, PCI, its subsidiaries
and affiliated professional corporations, including AVMG, provided to the bank a
first priority perfected security interest in all real and personal assets.
AVMG's outstanding common stock was also pledged to the bank. On May 19, 1998,
this credit facility was fully repaid, and all security interests and stock
pledges, including those of AVMG, were fully released.
 
REGULATORY MATTERS
 
    Laws and regulations governing the Medicare program are complex and subject
to interpretation. The Company believes that it is in compliance with all
applicable laws and regulations and is not aware of any pending or threatened
investigations involving allegations of potential wrongdoing. While no such
regulatory inquiries have been made, compliance with such laws and regulations
can be subject to future government review and interpretation as well as
significant regulatory action including fines, penalties, and exclusion from the
Medicare program.
 
YEAR 2000--UNAUDITED
 
    The Group processes its financial and operating data using PCI's centralized
computer systems. As certain assets of the Group were acquired on June 1, 1998
(see Note 7), and the operations of the Group's business were assumed by
Prospect Medical Holdings, Inc. (Prospect) on such date, subsequent financial
and operational transaction processing will be performed using separate computer
systems implemented for the Group by Prospect.
 
    Prospect's accounting software is currently capable of processing
transactions in the year 2000 and beyond. Prospect is implementing a purchase
contract for its management information system which provides for a software
upgrade to be installed in February 1999 to address year 2000 matters.
Implementation costs are not expected to be significant.
 
7. SUBSEQUENT EVENT AND CURRENT LIQUIDITY ISSUES
 
    On June 1, 1998, Prospect acquired certain assets of AVMG (primarily
goodwill and management rights to the Group). Of the total purchase price,
$500,000 is payable in cash, $500,000 in a short-term promissory note at an
annual interest rate of 8% and the balance in 200,000 shares of Prospect common
stock. Prospect intends to provide necessary funds to finance the Group's
working capital deficiency.

8. NOTE TO UNAUDITED INTERIM FINANCIAL STATEMENTS
 
    The unaudited financial information for the three-month periods ended March
31, 1998 and 1997, has been prepared in accordance with generally accepted
accounting principles for interim financial information. In the opinion of
management, all adjustments considered necessary for a fair presentation, which
consist solely of normal recurring adjustments, have been included. The interim
information should be read in conjunction with the financial statements for the
years ended December 31, 1997 and 1996. Operating results for interim periods
are not necessarily indicative of the results which may be expected for the
entire year.

1. BACKGROUND AND ORGANIZATION
 
    Sierra Primary Care Medical Group, a Medical Corporation (SPCMG) was
incorporated in 1984 as a primary care physician group which serves patients in
the communities of Lancaster and Palmdale, California. SPCMG is organized as a
C-corporation under the Internal Revenue Code.
 
    Sierra Medical Management, Inc. (SMM) was incorporated in April 1997, as a
healthcare management services organization which provides comprehensive medical
management services, organizational development and contracting support to
SPCMG. SMM is organized as a C-corporation under the Internal Revenue Code and
it commenced operations on June 1, 1997.
 
    SPCMG and SMM are owned and managed by two physician shareholders. Effective
May 21, 1997, SPCMG and SMM (collectively the Company) entered into a management
services agreement with an initial term of 30 years renewable for successive
10-year periods thereafter, unless terminated by either party with advance
written notice.
 
    Under the management services agreement, SMM agrees to provide
administrative and operational services such as contract management, network
development, provider and member services, marketing, financial reporting,
utilization review, case management, claims processing and payment, and quality
assurance for a fee, based upon a contractual formula.
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
BASIS OF PRESENTATION
 
    The combined financial statements include the accounts of SPCMG and SMM from
commencement of operations in April 1997. SPCMG and SMM are under common
ownership and management for all periods presented and these financial
statements represent the results of a single business enterprise. All
significant intercompany transactions and balances have been eliminated in
combination.
 
MEDICAL REVENUE AND COST RECOGNITION
 
    Net patient service revenue consists primarily of fees for medical services
provided by the Company under capitated contracts with health maintenance
organizations (HMOs). Capitation revenue under HMO contracts is prepaid monthly
to the Company based on the number of enrollees electing the Company as their
health care provider. The Company received approximately 92% of its net patient
service revenue under capitated arrangements for the nine months ended September
30, 1997, and the year ended December 31, 1996. The remainder of the Company's
revenue is derived under fee-for-service arrangements. For the nine months ended
September 30, 1997, three contracts accounted for 73% of the Company's capitated
enrollees and 49% of its revenue. These contracts accounted for 55% of the
Company's capitated enrollees and 47% of its revenue in 1996. HMO contracts
include provisions to share in the risk for hospitalization whereby the Company
can earn additional revenue or incur penalties based upon the utilization of
hospital services. Shared-risk revenues are estimated based upon hospital
utilization and associated costs incurred by assigned HMO enrollees, compared to
budgeted costs. Differences between actual contract settlements and estimated
amounts relating to HMO risk-sharing arrangements are recorded in the year of
final settlement.

                             A MEDICAL CORPORATION
                      AND SIERRA MEDICAL MANAGEMENT, INC.
 
               NOTES TO COMBINED FINANCIAL STATEMENTS (CONTINUED)
 
2. SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
    In connection with providing services to HMO enrollees, the Company is
responsible for all covered medical services provided to assigned HMO enrollees.
The cost of medical services is recognized in the period in which it is provided
and includes an estimate of the cost of services which have been incurred but
not yet reported. The estimate for accrued medical costs is based on actuarial
projections of costs using historical studies of claims paid. Estimates are
continually monitored and reviewed and, as settlements are made or estimates
adjusted, differences are reflected in current operations.
 
    The Company participates in reinsurance protection programs with the HMOs
which limit the amount of risk the Company ultimately bears by providing
reimbursement payments once medical services provided to an individual enrollee
exceed an agreed-upon amount. Reinsurance recoveries are recorded once the
attachment point is achieved and the amounts are collected from the HMOs.
 
DEPRECIATION
 
    Property and equipment are depreciated using the straight-line method over
the useful lives of the assets which range from five to seven years. Leasehold
improvements are amortized over the shorter of the useful lives or the lease
period.
 
MEDICAL MALPRACTICE LIABILITY INSURANCE
 
    The Company procures professional liability coverage on behalf of its
physicians on a claims-made basis of up to $1,000,000 per claim and a $3,000,000
annual aggregate. The insurance contract specifies that coverage is available
only during the term of each insurance contract and covers only those claims
reported while the policies are in force. The Company has renewed its policy
through September 30, 1998. Based on a review of prior claims experience,
including reporting patterns and the number and severity of claims, and in
consideration of the cost of available tail coverage, the Company has recorded
an estimate for incurred but not reported claims at September 30, 1997. There is
no assurance that the amount accrued will be adequate to cover actual claims
settled.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of revenues and expenses during the
reporting period. Actual results could differ from these estimates.
 
REGULATORY MATTERS
 
    Laws and regulations governing the Medicare program are complex and subject
to interpretation. The Company believes that it is in compliance with all
applicable laws and regulations and is not aware of any pending or threatened
investigations involving allegations of potential wrongdoing. Compliance with
such laws and regulations can be subject to future government review and
interpretation as well as significant regulatory action including fines,
penalties, and exclusion from the Medicare and Medicaid programs.

3. BENEFIT PLANS
 
    The Company sponsors a defined contribution plan (the Plan) for employees
who meet the minimum length of service and age requirements. The plan was
adopted in 1990. Eligible employees may contribute up to the statutory limit in
the Plan year. The Company may, at its discretion, match up to 25% of employee
contributions not to exceed 4% of an employee's compensation. The Company is
responsible for the administration of the Plan as the Plan administrator and
trustee.
 
    The Company's contributions totaled $8,742 for the nine months ended
September 30, 1997, and $11,377 for the year ended December 31, 1996.
 
4. INCOME TAXES
 
    The Company accounts for income taxes using the liability method as required
by Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" (SFAS No. 109). SFAS No. 109 is an asset and liability method which
requires the recognition of deferred tax assets and liabilities for the expected
future tax consequences of events that have been recognized in the Company's
financial statements or tax returns. In estimating future tax consequences, SFAS
No. 109 generally considers all expected future events other than enactments of
changes in the tax law or rates.
 
    The provision for income taxes is as follows:

    During fiscal 1996, the Internal Revenue Service (IRS) assessed additional
taxes of $131,690 and interest of $26,704 in the course of an audit of the
Company's tax returns for the years ended June 30, 1995 and 1994. These
assessments were paid in 1996. In fiscal 1997, the Company utilized its net
operating loss (NOL) carrybacks to reduce the additional taxable income in 1995
and 1994 as a result of the audit, and consequently received a refund of
$143,643. In January 1997, the Company also amended its 1995 and 1994 state
franchise tax returns to reflect the federal tax adjustments and paid additional
taxes of $31,265. Total assessments and additional taxes, net of the NOL
benefit, of $19,312 have been included in the provision for income taxes for
1996.
 
5. RELATED PARTY TRANSACTIONS
 
    The shareholders of the Company are partners in Sierra Medical Group
Partnership (the Partnership), an affiliated medical group which comprises
primary care and specialist physicians. The Partnership's sole contract is a
provider services agreement with the Company to provide medical services to its
HMO enrollees. As consideration for its services, the Partnership receives a
percentage of the Company's total capitation revenue, which is determined at the
discretion of the Company's board of directors and is adjusted periodically
(13.5% for the nine months ended September 30, 1997, and the year ended December
31, 1996). Payments to the Partnership totaled $1,152,943 for the nine months
ended September 30, 1997, and $1,419,526 for the year ended December 31, 1996.
The Company also contracts with other non-affiliated specialists, who are
reimbursed on a discounted fee-for-service basis.
 
    One physician shareholder also provides specialty services to the Company's
patients. Fees paid to the physician shareholder totaled $142,296 for the nine
months ended September 30, 1997, and $218,415 for the year ended December 31,
1996.
 
    The Company leases medical facilities and office space from companies owned
by the physician shareholders. The leases expire between 1998 and 2001 at total
monthly payments of $52,124. Total rental expense under these leases for the
nine months ended September 30, 1997, was $469,116 and $625,488 for the year
ended December 31, 1996.

6. SUBSEQUENT EVENT
 
    Effective September 25, 1997, Prospect Medical Holdings, Inc. (Prospect),
together with a physician shareholder, purchased the outstanding common stock of
SPCMG and SMM for total consideration of $10,200,000 consisting of $6,500,000 in
cash, promissory notes of $2,500,000 bearing interest at 7%, and 600,000 shares
valued at $2 per share of Prospect common stock. Principal on the notes is due
in quarterly installments of $125,000 and an annual payment of $250,000.
Simultaneous with this purchase transaction, Prospect Medical Systems, Inc.
(Systems), a subsidiary of Prospect, entered into a long-term management and
assignment of revenues agreement with SPCMG with an initial 30-year term,
renewable for successive 10-year periods thereafter. All revenues for the
performance of medical services are assigned to Systems. In exchange, Systems
has agreed to provide financial, management, information systems, marketing,
advertising and public relations, risk management, and administrative support
for utilization review and quality care. Additionally, Systems at its cost, has
assumed the obligations of the facilities, medical and non-medical supplies, and
employment of non-physician personnel. All remaining funds are remitted to the
Company, from which the costs of all medical services are paid. The management
fee earned by Systems fluctuates based on the profitability of the Company as
Systems retains a 50% residual interest in the net profits of the Company.

                               DECEMBER 31, 1997
 
1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES
 
BUSINESS DESCRIPTION
 
    Santa Ana-Tustin Physicians Group, Inc. (the Company) is an independent
physicians association (IPA) incorporated in 1981 which operates in Orange
County, California, and provides medical services primarily through capitated
contracts with health maintenance organizations (HMOs). The Company's healthcare
services are performed by employed physicians, independent providers and by IPAs
under contract with the Company. In addition, the Company provides management
services to various unaffiliated medical groups and IPAs. The Company is
organized as a C-corporation under the Internal Revenue Code.
 
MEDICAL REVENUES AND COST RECOGNITION
 
    Net patient service revenue consists primarily of fees for medical services
provided by the Company under capitated contracts with HMOs. Capitated revenue
under HMO contracts is prepaid monthly to the Company based on the number of
enrollees electing the Company as their health care provider. The Company
received approximately 97% of its net patient service revenue under capitated
arrangements for the period January 1, 1997 to July 13, 1997, and the ten months
ended December 31, 1996. The remainder of the Company's revenue is derived under
fee-for-service arrangements. Three contracts accounted for 97% and 95% of the
Company's revenue for the period January 1, 1997 to July 13, 1997, and for the
ten months ended December 31, 1996, respectively. HMO contracts include
provisions to share in the risk for hospitalization whereby the Company can earn
additional revenue or incur penalties based upon the utilization of hospital
services. Estimated shared-risk amounts due from the HMOs are estimated based
upon hospital utilization and associated costs incurred by the assigned HMO
enrollees, compared to budgeted costs. Differences between actual contract
settlements and estimated amounts relating to HMO risk-sharing arrangements are
recorded in the year of final settlement.
 
    In connection with providing services to HMO enrollees, the Company is
responsible for all covered medical services provided to assigned HMO enrollees.
The costs of medical services are recognized in the period in which they are
provided and include an estimate of the costs of services which have been
incurred but not yet reported. The estimate for accrued medical costs is based
on actuarial projections of costs using historical studies for claims paid.
Estimates are continually monitored and reviewed and, as settlements are made or
estimates adjusted, differences are reflected in current operations.
 
    The Company participates in reinsurance protection programs with the HMOs
which limit the amount of risk the Company ultimately bears by providing
reimbursement payments once the medical services provided to an individual
enrollee exceed an agreed-upon amount. Reinsurance recoveries are recorded once
the attachment point is achieved and the amounts are collected from the HMOs.
 
MANAGEMENT FEE REVENUE
 
    Management fee revenue consists of management fees from Western Individual
Practice Association and Premier Medical Group for provision of non-medical
practice support services. Management fees are recorded in the period the
services are rendered.

                   NOTES TO FINANCIAL STATEMENTS (CONTINUED)
 
1. OPERATIONS AND SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)
DEPRECIATION
 
    Property and equipment are depreciated using the Modified Cost Recovery
System (MACRS) method, which method is similar to an accelerated method of
depreciation, over the estimated useful life of each class of depreciable
assets.
 
MEDICAL MALPRACTICE LIABILITY INSURANCE
 
    The Company procures professional liability coverage on behalf of its
physicians on a claims-made basis of up to $2,000,000 per claim and a $4,000,000
annual aggregate with no deductible. The insurance contract specifies that
coverage is available only during the term of each insurance contract and covers
only those claims reported while the policies are in force. The Company has
renewed its policy through June 1, 1998. Based on a review of prior claims
experience, including reporting patterns and the number and severity of claims,
and in consideration of the cost of available tail coverage, the Company
determined that incurred but not reported claims were not significant at
September 30, 1997. There is no assurance that actual claims will not exceed
management's estimate.
 
USE OF ESTIMATES
 
    The preparation of financial statements in conformity with generally
accepted accounting principles requires management to make estimates and
assumptions that affect the reported amounts of assets and liabilities and
disclosure of contingent assets and liabilities as of the date of the financial
statements. Estimates also affect the reported amounts of revenues and expenses
during the reporting period. Actual results could differ from those estimates.
 
REGULATORY MATTERS
 
    Laws and regulations governing the Medicare program are complex and subject
to interpretation. The Company believes that it is in compliance with all
applicable laws and regulations and is not aware of any pending or threatened
investigations involving allegations of potential wrongdoing. Compliance with
such laws and regulations can be subject to future government review and
interpretation as well as significant regulatory action including fines,
penalties, and exclusion from the Medicare and Medicaid programs.
 
RECLASSIFICATIONS
 
    Certain prior period account balances have been reclassified to conform with
the 1997 financial statements presentation.
 
2. INCOME TAXES
 
    The Company accounts for income taxes using the liability method as required
by Statement of Financial Accounting Standards No. 109, "Accounting for Income
Taxes" (SFAS No. 109). SFAS No. 109 is an asset and liability method which
requires the recognition of deferred tax assets and liabilities for the expected
future tax consequences of events that have been recognized in the Company's
financial statements or tax returns. In estimating future tax consequences, SFAS
No. 109 generally considers all expected future events other than enactments of
changes in the tax law or rates.

ITEM 14.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
    The Registrant is a Delaware corporation. Section 145 of the Delaware
General Corporation Law ("DGCL") provides that a corporation may indemnify any
person who was or is a party or is threatened tobe made a party to any
threatened, pending or completed action, suit or proceeding, whether civil,
criminal, administrative or investigative (other than an action by or in the
right of the corporation) by reason of the fact that such person is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid
in settlement actually and reasonably incurred by such person in connection with
such action, suit or proceeding if such person acted in good faith and in a
manner such person reasonably believed to be in or not opposed to the best
interests of the corporation, and, with respect to any criminal action or
proceeding, had no reasonable cause to believe such person's conduct was
unlawful.
 
    Section 145 further provides that a corporation may indemnify any person who
was or is a party or is threatened to be made a party to any threatened, pending
or completed action or suit by or in the right of the corporation to procure a
judgment in its favor by reason of the fact that such person is or was a
director, officer, employee or agent of the corporation, or is or was serving at
the request of the corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees) actually and reasonably incurred by
such person in connection with the defense or settlement of such action or suit
if such person acted in good faith and in a manner such person reasonably
believed to be in or not opposed to the best interests of the corporation and
except that no indemnification shall be made in respect of any claim, issue or
matter as to which such person shall have been adjudged to be liable to the
corporation unless and only to the extent that the Delaware Court of Chancery or
the court in which such action or suit was brought shall determine that, despite
an adjudication of liability but in view of all the circumstances of the case,
such person is fairly and reasonably entitled to indemnity for such expenses
which the Court of Chancery or such other court shall deem proper.
 
    Additionally, Section 145 provides that indemnification pursuant to its
provisions ("permissive indemnification") shall not be deemed exclusive of any
other rights to which a person seeking indemnification may be entitled under any
bylaw, agreement, vote of stockholders or disinterested directors or
 
                                      II-1
<PAGE>
otherwise, both as to action in such person's official capacity and as to action
in another capacity while holding such office.
 
    The indemnification provisions in Article V of the Registrant's Bylaws are
substantially consistent with the permissive indemnification provisions of
Section 145 of the DGCL.
 
    Paragraph 8 of the Registrant's Certificate of Incorporation provides
generally that each person who was or is made a party or is threatened to be
made a party to or is otherwise involved in any action, suit or proceeding by
reason of the fact that he or she is or was a director or officer of the
Registrant or, while a director or officer of the Registrant, is or was serving
at the request of the Registrant as a director, officer, employee or agent of
another entity or enterprise, shall be indemnified and held harmless by the
Registrant to the fullest extent authorized by the DGCL against all expense,
liability and loss reasonably incurred or suffered in connection therewith. Such
right to indemnification is deemed a contract right and is not exclusive of any
right which any person may have or acquire under any statute, provision of the
Certificate of Incorporation, Bylaw, agreement, vote of stockholders or
disinterested directors or otherwise. In any suit brought against the Registrant
to enforce such indemnification right, it shall be a defense that the person
seeking indemnification has not met the applicable standard of conduct set forth
in the DGCL. Further, no person who is entitled to indemnification under
Paragraph 8 shall be entitled to payment of consequential damages, including,
without limitation, damages for inconvenience, emotional distress, lost profits,
injury to privacy, publicity or reputation, or punitive damages.
 
    Paragraph 7 of the Registrant's Certificate of Incorporation provides that
no director of the Registrant shall be personally liable to the Registrant or
its stockholders for monetary damages for any breach of fiduciary duty by such
director as a director. Notwithstanding the foregoing sentence, a director shall
be liable to the extent provided by applicable law (i) for any breach of the
director's duty of loyalty to the Registrant or its stockholders, (ii) for acts
or omissions not in good faith or which involve intentional misconduct or a
knowing violation of law, (iii) pursuant to Section 174 of the DGCL, or (iv) for
any transaction from which the director derived an improper personal benefit.
 
    The Registrant also has purchased a liability insurance policy which insures
its directors and officers against certain liabilities, including liabilities
under the Securities Act of 1933, as amended ("Securities Act").
 
ITEM 15.  RECENT SALES OF UNREGISTERED SECURITIES.
 
    Except as otherwise indicated, the Registrant believes that each of the
transactions described in the table below was exempt from the registration
requirements of the Securities Act pursuant to Section 4(2) as a transaction not
involving any public offering. In each case, the number of investors was
limited, the investors were either accredited or otherwise qualified and had
access to material information about the Registrant, and restrictions were
placed on the resale of the securities sold. Where appropriate, the numbers of
securities shown in the table have been adjusted to reflect the 1:44 reverse
stock split which became effective on July 31, 1996.

ITEM 17. UNDERTAKINGS.
 
    (a) The undersigned Registrant hereby undertakes:
 
        (1) To file, during any period in which offers or sales are being made,
    a post-effective amendment to this Registration Statement:
 
           (i) To include any prospectus required by section 10(a)(3) of the
               Securities Act;
 
           (ii) To reflect in the prospectus any facts or events arising after
               the effective date of the Registration Statement (or the most
               recent post-effective amendment thereof) which, individually or
               in the aggregate, represent a fundamental change in the
               information set forth in the Registration Statement.
               Notwithstanding the foregoing, any increase or decrease in volume
               of securities offered (if the total dollar value of securities
               offered would not exceed that which was registered) and any
               deviation from the low or high end of the estimated maximum
               offering range may be reflected in the form of prospectus filed
               with the Securities and Exchange Commission pursuant to Rule
               424(b) if, in the aggregate, the changes in volume and price
               represent no more than 20% change in the maximum aggregate
               offering price set forth in the "Calculation of Registration Fee"
               table in the effective Registration Statement.
 
           (iii) To include any material information with respect to the plan of
               distribution not previously disclosed in the Registration
               Statement or any material change to such information in the
               registration statement;
 
        (2) That, for the purpose of determining any liability under the
    Securities Act, each such post-effective amendment shall be deemed to be a
    new registration statement relating to the securities offered therein, and
    the offering of such securities at that time shall be deemed to be the
    initial bona fide offering thereof.
 
        (3) To remove from registration by means of a post-effective amendment
    any of the securities being registered which remain unsold at the
    termination of the offering.
 
    (f) The undersigned Registrant hereby undertakes to provide to the
       Underwriters at the closing specified in the Underwriting Agreement
       certificates in such denominations and registered in such names as
       required by the Underwriters to permit prompt delivery to each purchaser.
 
    (h) Insofar as indemnification for liabilities arising under the Securities
       Act may be permitted to directors, officers and controlling persons of
       the Registrant pursuant to the foregoing provisions, or otherwise, the
       Registrant has been advised that in the opinion of the Securities and
       Exchange Commission such indemnification is against public policy as
       expressed in the Securities Act and is, therefore, unenforceable. In the
       event that a claim for indemnification against such liabilities (other
       than the payment by the Registrant of expenses incurred or paid by a
       director, officer or controlling person of the Registrant in the
       successful defense of any action, suit or proceeding) is asserted by such
       director, officer or controlling person in connection with the securities
       being registered, the Registrant will, unless in the opinion of its
       counsel the matter has been settled by controlling precedent, submit to a
       court of appropriate jurisdiction the question whether such

SECURITY CAPITAL TRADING, INC. 
  As Representative of the several Underwriters
  named in Schedule A annexed hereto 
520 Madison Avenue 
10th Floor 
New York, New York 10022 

Ladies and Gentlemen: 

    Prospect Medical Holdings, Inc., a Delaware corporation (the "Company"),
confirms its agreement with Security Capital Trading, Inc. ("Security Capital")
and each of the underwriters named in Schedule A hereto (collectively, the
"Underwriters," which term shall also include any underwriter substituted as
hereinafter provided in Section 11), for whom Security Capital is acting as
Representative (in such capacity, Security Capital shall hereinafter be referred
to as "you" or the "Representative"), with respect to the sale by the Company
and the purchase by the Underwriters, acting severally and not jointly, of the
respective number of shares ("Shares") of the Company's common stock, $0.01 par
value per share ("Common Stock"), and redeemable common stock purchase warrants
(the "Redeemable Warrants"), each to purchase one share of Common Stock, set
forth in Schedule A hereto. The aggregate 3,000,000 shares of Common Stock and
3,000,000 Redeemable Warrants will be separately tradable upon issuance and are
hereinafter referred to as the "Firm Securities."  Each Redeemable Warrant is
exercisable commencing on _____________________, 1999 [one year from the date
of this Agreement] until ____________________, 2003 [60 months from the date
of this Agreement], unless previously redeemed by the Company, at an initial
exercise price of $______________ [140% of the initial public offering price per
share of Common Stock] per share of Common Stock. The Redeemable Warrants may be
redeemed by the Company at a redemption price of $.10 per Redeemable Warrant at
any time after _________________, 1999 [one year from the date of this
Agreement] on thirty (30) days' prior written notice, provided that the closing
bid price of the Common Stock equals or exceeds $18.00 per share, for any twenty
(20) trading days within a period of thirty (30) consecutive trading days ending
on the fifth trading day prior to the notice of 


<PAGE>

redemption, all in accordance with the terms and conditions of the Warrant 
Agreement (as hereinafter defined). 

    Upon your request, as provided in Section 2(b) of this Agreement, the 
Company shall also issue and sell to the Underwriters, acting severally and 
not jointly, up to an additional 450,000 shares of Common Stock and/or 
450,000 Redeemable Warrants for the purpose of covering over-allotments, if 
any. Such 450,000 shares of Common Stock and 450,000 Redeemable Warrants are 
hereinafter collectively referred to as the "Option Securities." The Company 
also proposes to issue and sell to you warrants (the "Representative's 
Warrants") pursuant to the Representative's Warrant Agreement (the 
"Representative's Warrant Agreement") for the purchase of an additional 
300,000 shares of Common Stock and/or 300,000 Redeemable Warrants. The shares 
of Common Stock and Redeemable Warrants issuable upon exercise of the 
Representative's Warrants are hereinafter referred to as the 
"Representative's Securities." The Firm Securities, the Option Securities, 
the Representative's Warrants and the Representative's Securities 
(collectively, hereinafter referred to as the "Securities") are more fully 
described in the Registration Statement and the Prospectus referred to below. 

    1.   REPRESENTATIONS AND WARRANTIES OF THE COMPANY.  The Company 
represents and warrants to, and agrees with, each of the Underwriters as of 
the date hereof, and as of the Closing Date (as hereinafter defined) and each 
Option Closing Date (as hereinafter defined), if any, as follows: 

         (a)  The Company has prepared and filed with the Securities and
Exchange Commission (the "Commission") a registration statement, and an
amendment or amendments thereto, on Form S-1 (No. 333-_______________),
including any related preliminary prospectus ("Preliminary Prospectus"), for the
registration of the Firm Securities, the Option Securities and the
Representative's Securities under the Securities Act of 1933, as amended (the
"Act"), which registration statement and amendment or amendments have been
prepared by the Company in conformity with the requirements of the Act, and the
rules and regulations (the "Regulations") of the Commission under the Act. 
Except as the context may otherwise require, such registration statement, as
amended, on file with the Commission at the time the registration statement
becomes effective (including the prospectus, financial statements, schedules,
exhibits and all other documents filed as a part thereof or incorporated therein
(including, but not limited to, those documents or information incorporated by
reference therein) and all information deemed to be a part thereof as of such
time pursuant to paragraph (b) of Rule 430(A) of the Regulations), is
hereinafter called the "Registration Statement", and the form of prospectus in
the form first filed with the Commission pursuant to Rule 424(b) of the
Regulations, is hereinafter called the "Prospectus." For purposes hereof, "Rules
and Regulations" mean the rules and regulations adopted by the Commission under
either the Act or the Securities Exchange Act of 1934, as amended (the "Exchange
Act"), as applicable. 

         (b)  Neither the Commission nor any state regulatory authority has
issued any order preventing or suspending the use of any Preliminary Prospectus,
the Registration Statement or Prospectus or any part of any thereof and no
proceedings for a stop order suspending the effectiveness of the Registration
Statement or any of the Company's securities have been instituted 


                                      2

<PAGE>

or are pending or threatened.  Each of the Preliminary Prospectus, the 
Registration Statement and Prospectus at the time of filing thereof conformed 
with the requirements of the Act and the Regulations, and none of the 
Preliminary Prospectus, the Registration Statement or Prospectus at the time 
of filing thereof contained an untrue statement of a material fact or omitted 
to state a material fact required to be stated therein or necessary to make 
the statements therein, in light of the circumstances under which they were 
made, not misleading, except that this representation and warranty does not 
apply to statements made in reliance upon and in conformity with written 
information furnished to the Company with respect to the Underwriters by or 
on behalf of the Underwriters expressly for use in such Preliminary 
Prospectus, Registration Statement or Prospectus or any amendment thereof or 
supplement thereto. 

         (c)  When the Registration Statement becomes effective and at all
times subsequent thereto up to the Closing Date (as defined herein) and each
Option Closing Date (as defined herein), if any, and during such longer period
as the Prospectus may be required to be delivered in connection with sales by
the Underwriters or a dealer, the Registration Statement and the Prospectus will
contain all statements which are required to be stated therein in accordance
with the Act and the Regulations, and will conform to the requirements of the
Act and the Regulations; neither the Registration Statement nor the Prospectus,
nor any amendment or supplement thereto, will contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary to make the statements therein, in light of the circumstances under
which they were made, not misleading, provided, however, that this
representation and warranty does not apply to statements made or statements
omitted in reliance upon and in strict conformity with information furnished to
the Company in writing by or on behalf of any Underwriter expressly for use in
the Preliminary Prospectus, Registration Statement or Prospectus or any
amendment thereof or supplement thereto. 

         (d)  The Company has been duly organized and is validly existing as a
corporation in good standing under the laws of the state of its incorporation.
Except as set forth in the Prospectus, the Company does not own an interest in
any corporation, partnership, trust, joint venture or other business entity. The
Company is duly qualified and licensed and in good standing as a foreign
corporation in each jurisdiction in which its ownership or leasing of any
properties or the character of its operations requires such qualification or
licensing. The Company has all requisite power and authority (corporate and
other), and has obtained any and all necessary authorizations, approvals,
orders, licenses, certificates, franchises and permits of and from all
governmental or regulatory officials and bodies (including, without limitation,
those having jurisdiction over environmental or similar matters), to own or
lease its properties and conduct its business as described in the Prospectus;
the Company is and has been doing business in compliance with all such
authorizations, approvals, orders, licenses, certificates, franchises and
permits and all applicable federal, state, local and foreign laws, rules and
regulations; and the Company has not received any notice of proceedings relating
to the revocation or modification of any such authorization, approval, order,
license, certificate, franchise, or permit which, singly or in the aggregate, if
the subject of an unfavorable decision, ruling or finding, would materially and
adversely affect the condition, financial or otherwise, or the earnings,
position, prospects, value, operation, properties, business or results of
operations of the Company. The disclosures in the Registration Statement
concerning the effects of federal, state, local, and foreign laws, rules and
regulations on the Company's business as currently 


                                      3

<PAGE>

conducted and as contemplated are correct in all material respects and do not 
omit to state a material fact required to be stated therein or necessary to 
make the statements contained therein not misleading in light of the 
circumstances under which they were made. 

         (e)  The Company has a duly authorized, issued and outstanding
capitalization as set forth in the Prospectus under "Capitalization" and
"Description of Capital Stock" and will have the adjusted capitalization set
forth therein under "Capitalization" on the Closing Date and each Option Closing
Date, if any, based upon the assumptions set forth therein, and the Company is
not a party to or bound by any instrument, agreement or other arrangement
providing for it to issue any capital stock, rights, warrants, options or other
securities, except for this Agreement, the Warrant Agreement, the
Representative's Warrant Agreement and as described in the Prospectus. The
Securities and all other securities issued or issuable by the Company conform
or, when issued and paid for, will conform, in all respects to all statements
with respect thereto contained in the Registration Statement and the Prospectus.
All issued and outstanding securities of the Company have been duly authorized
and validly issued and are fully paid and non-assessable and the holders
thereof have no rights of rescission with respect thereto, and are not subject
to personal liability by reason of being such holders; and none of such
securities were issued in violation of the preemptive rights of any holders of
any security of the Company or similar contractual rights granted by the
Company. The Securities are not and will not be subject to any preemptive or
other similar rights of any stockholder, have been duly authorized and, when
issued, paid for and delivered in accordance with the terms hereof, will be
validly issued, fully paid and non-assessable and will conform to the
description thereof contained in the Prospectus; the holders thereof will not be
subject to any liability solely as such holders; all corporate action required
to be taken for the authorization, issuance and sale of the Securities has been
duly and validly taken; and the certificates representing the Securities will be
in due and proper form. Upon the issuance and delivery pursuant to the terms
hereof of the Securities to be sold by the Company hereunder, the Underwriters
or the Representative, as the case may be, will acquire good and marketable
title to such Securities free and clear of any lien, charge, claim, encumbrance,
pledge, security interest, defect or other restriction or equity of any kind
whatsoever. 

         (f)  The financial statements of the Company, together with the
related notes and schedules thereto, included in the Registration Statement,
each Preliminary Prospectus and the Prospectus fairly present the financial
position, changes in cash flow, changes in stockholders' equity and the results
of operations of the Company at the respective dates and for the respective
periods to which they apply and such financial statements have been prepared in
conformity with generally accepted accounting principles and the Rules and
Regulations, consistently applied throughout the periods involved and such
financial statements have been examined by Ernst & Young LLP and BDO Seidman,
LLP, who are independent certified public accountants with respect to the
Company. There has been no adverse change or development involving a prospective
adverse change in the condition, financial or otherwise, or in the earnings,
position, prospects, value, operation, properties, business, or results of
operations of the Company, whether or not arising in the ordinary course of
business, since the date of the financial statements included in the
Registration Statement and the Prospectus and the outstanding debt, the
property, both tangible and intangible, and the business of the Company, conform
in all material respects to the descriptions thereof contained in the
Registration Statement and the Prospectus. The financial disclosures (including,
without limitation, 


                                      4

<PAGE>

any pro forma financial information) set forth in the Prospectus under the 
headings "Selected Consolidated Financial Data," "Capitalization," and 
"Management's Discussion and Analysis of Financial Condition and Results of 
Operations," fairly present, on the basis stated in the Prospectus, the 
information set forth therein, and have been derived from or compiled on a 
basis consistent with that of the audited financial statements included in 
the Prospectus; and, in the case of pro forma financial information, if any, 
the assumptions used in the preparation thereof are reasonable and the 
adjustments used therein are appropriate to give effect to the transactions 
and circumstances referred to therein. The amounts shown as accrued for 
current and deferred income and other taxes in such financial statements are 
sufficient for the payment of all accrued and unpaid federal, state, local 
and foreign income taxes, interest, penalties, assessments or deficiencies 
applicable to the Company, whether disputed or not, for the applicable period 
then ended and periods prior thereto; adequate allowance for doubtful 
accounts has been provided for unindemnified losses due to the operations of 
the Company; and the statements of income do not contain any items of special 
or nonrecurring income not earned in the ordinary course of business, except 
as specified in the notes thereto. 

         (g)  The Company (i) has paid all due and payable federal, state,
local, and foreign taxes for which it is liable, including, but not limited to,
withholding taxes and amounts payable under Chapters 21 through 24 of the
Internal Revenue Code of 1986, as amended (the "Code"), and has furnished all
information returns it is required to furnish pursuant to the Code, (ii) has
established adequate reserves for such taxes which are not due and payable, and
(iii) does not have any tax deficiency or claims outstanding, proposed or
assessed against it. 

         (h)  No transfer tax, stamp duty or other similar tax is payable by or
on behalf of the Underwriters in connection with (i) the issuance by the Company
of the Securities, (ii) the purchase by the Underwriters of the Firm Securities
and the Option Securities from the Company and the purchase by the
Representative of the Representative's Warrants from the Company, (iii) the
consummation by the Company of any of its obligations under this Agreement, or
(iv) resales of the Firm Securities and the Option Securities in connection with
the distribution contemplated hereby. 

         (i)  The Company maintains insurance policies, including, but not
limited to, general liability, malpractice and property insurance, which insures
each of the Company and its employees, against such losses and risks generally
insured against by comparable businesses.  The Company (A) has not failed to
give notice or present any insurance claim with respect to any matter, including
but not limited to the Company's business, property or employees, under any
insurance policy or surety bond in a due and timely manner, (B) does not have
any disputes or claims against any underwriter of such insurance policies or
surety bonds and has not failed to pay any premiums due and payable thereunder,
and (C) has not failed to comply with all conditions contained in such insurance
policies and surety bonds.  There are no facts or circumstances under any such
insurance policy or surety bond which would relieve any insurer of its
obligation to satisfy in full any valid claim of the Company. 

         (j)  There is no action, suit, proceeding, inquiry, arbitration,
investigation, litigation or governmental proceeding (including, without
limitation, those relating to environmental or similar matters), domestic or
foreign, pending or  threatened against (or circumstances that are reasonably
likely to give rise to the same), or involving the properties or business of,
the Company 


                                      5

<PAGE>

which (i) questions the validity of the capital stock of the Company, this 
Agreement, the Warrant Agreement or the Representative's Warrant Agreement, 
or of any action taken or to be taken by the Company pursuant to or in 
connection with this Agreement, the Warrant Agreement or the Representative's 
Warrant Agreement, (ii) is required to be disclosed in the Registration 
Statement which is not so disclosed (and such proceedings as are summarized 
in the Registration Statement are accurately summarized in all material 
respects), or (iii) might materially and adversely affect the condition, 
financial or otherwise, or the earnings, position, prospects, stockholders' 
equity, value, operation, properties, business or results of operations of 
the Company. 

         (k)  The Company has full legal right, power and authority to
authorize, issue, deliver and sell the Securities, enter into this Agreement,
the Warrant Agreement and the Representative's Warrant Agreement and to
consummate the transactions provided for in this Agreement, the Warrant
Agreement and the Representative's Warrant Agreement; and this Agreement, the
Warrant Agreement and the Representative's Warrant Agreement have each been duly
and properly authorized, executed and delivered by the Company. Each of this
Agreement, the Warrant Agreement and the Representative's Warrant Agreement
constitutes a legal, valid and binding agreement of the Company enforceable
against the Company in accordance with its terms, and none of the Company's
issuance and sale of the Securities, execution or delivery of this Agreement,
the Warrant Agreement or the Representative's Warrant Agreement, its performance
hereunder and thereunder, its consummation of the transactions contemplated
herein and therein, or the conduct of its business as described in the
Registration Statement, the Prospectus, and any amendments or supplements
thereto, conflicts with or will conflict with or results or will result in any
breach or violation of any of the terms or provisions of, or constitutes or will
constitute a default under, or result in the creation or imposition of any lien,
charge, claim, encumbrance, pledge, security interest, defect or other
restriction or equity of any kind whatsoever upon, any property or assets
(tangible or intangible) of the Company pursuant to the terms of (i) the
certificate of incorporation or by-laws of the Company, (ii) any license,
contract, collective bargaining agreement, indenture, mortgage, deed of trust,
lease, voting trust agreement, stockholders agreement, note, loan or credit
agreement or any other agreement or instrument to which the Company is a party
or by which the Company is or may be bound or to which it or its assets
(tangible or intangible) is or may be subject, or any indebtedness, or (iii) any
statute, judgment, decree, order, rule or regulation applicable to the Company
of any arbitrator, court, regulatory body or administrative agency or other
governmental agency or body (including, without limitation, those having
jurisdiction over environmental or similar matters), domestic or foreign, having
jurisdiction over the Company or any of its activities or properties.

         (l)  No consent, approval, authorization or order of, and no filing
with, any court, regulatory body, government agency or other body, domestic or
foreign, is required for the issuance of the Securities in the manner described
in the Prospectus and the Registration Statement, the performance of this
Agreement, the Warrant Agreement and the Representative's Warrant Agreement and
the transactions contemplated hereby and thereby, including without limitation,
any waiver of any preemptive, first refusal or other rights that any entity or
person may have for the issuance and/or sale of any of the Securities, except
such as have been or may be obtained under the Act or may be required under
state securities or Blue Sky laws or by the National Association of Securities
Dealers, Inc. ("NASD") in connection with the Underwriters' purchase and
distribution 


                                       6

<PAGE>

of the Firm Securities and the Option Securities, and the Representative's 
Warrants to be sold by the Company hereunder. 

         (m)  All executed agreements, contracts or other documents or copies
of executed agreements, contracts or other documents filed as exhibits to the
Registration Statement to which the Company is a party or by which it may be
bound or to which its assets, properties or business may be subject have been
duly and validly authorized, executed and delivered by the Company and
constitute the legal, valid and binding agreements of the Company, as the case
may be, enforceable against it in accordance with their respective terms. The
descriptions in the Registration Statement of agreements, contracts and other
documents are accurate and fairly present the information required to be shown
with respect thereto by Form S-1, and there are no contracts or other documents
which are required by the Act to be described in the Registration Statement or
filed as exhibits to the Registration Statement which are not described or filed
as required, and the exhibits which have been filed are complete and correct
copies of the documents of which they purport to be copies. 

         (n)  Subsequent to the respective dates as of which information is set
forth in the Registration Statement and Prospectus, and except as may otherwise
be indicated or contemplated herein or therein, the Company has not (i) issued
any securities or incurred any liability or obligation, direct or contingent,
for borrowed money, (ii) entered into any transaction other than in the ordinary
course of business, or (iii) declared or paid any dividend or made any other
distribution on or in respect of its capital stock of any class, and there has
not been any change in the capital stock, or any change in the debt (long or
short term) or liabilities, or material adverse change in or affecting the
general affairs, management, financial operations, stockholders' equity or
results of operations, of the Company. 

         (o)  No default exists in the due performance and observance of any
term, covenant or condition of any license, contract, collective bargaining
agreement, indenture, mortgage, installment sale agreement, lease, deed of
trust, voting trust agreement, stockholders agreement, partnership agreement,
note, loan or credit agreement, purchase order, or any other agreement or
instrument evidencing an obligation for borrowed money, or any other material
agreement or instrument to which the Company is a party or by which the Company
may be bound or to which the property or assets (tangible or intangible) of the
Company is subject or affected which might materially and adversely affect the
business, financial condition or operations of the Company. 

         (p)  The Company has generally enjoyed a satisfactory
employer-employee relationship with its employees and is in compliance with all
federal, state, local and foreign laws and regulations respecting employment and
employment practices, terms and conditions of employment and wages and hours. 
There are no pending investigations involving the Company by the U.S. Department
of Labor, or any other governmental agency responsible for the enforcement of
such federal, state, local, or foreign laws and regulations. There is no unfair
labor practice charge or complaint against the Company pending before the
National Labor Relations Board or any lockout, strike, picketing, boycott,
dispute, slowdown or stoppage pending or threatened against or involving the
Company, or any predecessor entity, and none has ever occurred. No
representation question exists respecting the employees of the Company, and no
collective bargaining agreement 


                                      7

<PAGE>

or modification thereof is currently being negotiated by the Company. No 
grievance or arbitration proceeding is pending under any expired or existing 
collective bargaining agreements of the Company. No labor dispute with the 
employees of the Company exists or is imminent. 

         (q)  The Company does not maintain, sponsor or contribute to any
program or arrangement that is an "employee pension benefit plan," an "employee
welfare benefit plan," or a "multiemployer plan" as such terms are defined in
Sections 3(2), 3(1) and 3(37), respectively, of the Employee Retirement Income
Security Act of 1974, as amended ("ERISA") ("ERISA Plans").  The Company does
not maintain or contribute, now or at any time previously, to a defined benefit
plan, as defined in Section 3(35) of ERISA.  No ERISA Plan (or any trust created
thereunder) has engaged in a "prohibited transaction" within the meaning of
Section 406 of ERISA or Section 4975 of the Code, which could subject the
Company to any tax penalty on prohibited transactions and which has not
adequately been corrected.  Each ERISA Plan is in compliance with all reporting,
disclosure and other requirements of the Code and ERISA as they relate to any
such ERISA Plan.  Determination letters have been received from the Internal
Revenue Service with respect to each ERISA Plan which is intended to comply with
Code Section 401(a), stating that such ERISA Plan and the attendant trust are
qualified thereunder.  The Company has never completely or partially withdrawn
from a "multiemployer plan." 

         (r)  Neither the Company, nor any of its employees, directors,
stockholders, partners, or affiliates (within the meaning of the Regulations) of
any of the foregoing has taken or will take, directly or indirectly, any action
designed to or which has constituted or which might be expected to cause or
result in, under the Exchange Act, or otherwise, stabilization or manipulation
of the price of any security of the Company to facilitate the sale or resale of
the Securities or otherwise. 

         (s)  Except as otherwise disclosed in the Prospectus, none of the
patents, patent applications, trademarks, service marks, trade names and
copyrights, and licenses and rights to the foregoing presently owned or held by
the Company, so far as known by the Company, are in dispute  or are in any
conflict with the right of any other person or entity.  The Company (i) owns or
has the right to use, free and clear of all liens, charges, claims,
encumbrances, pledges, security interests, defects or other restrictions or
equities of any kind whatsoever, all patents, trademarks, service marks, trade
names and copyrights, technology and licenses and rights with respect to the
foregoing, used in the conduct of its business as now conducted or proposed to
be conducted without infringing upon or otherwise acting adversely to the right
or claimed right of any person, corporation or other entity under or with
respect to any of the foregoing and (ii) is not obligated or under any liability
whatsoever to make any payment by way of royalties, fees or otherwise to any
owner or licensee of, or other claimant to, any patent, trademark, service mark,
trade name, copyright, know-how, technology or other intangible asset, with
respect to the use thereof or in connection with the conduct of its business or
otherwise. 

         (t)  The Company has good and marketable title to, or valid and
enforceable leasehold estates in, all material items of real and personal
property stated in the Prospectus to be owned or leased by it, free and clear of
all liens, charges, claims, encumbrances, pledges, security interests, defects,

with the Commission as a part of the Registration Statement, are independent
certified public accountants with respect to the Company as required by the Act
and the Rules and Regulations. 

         (v)  The Company has caused to be duly executed legally binding and
enforceable agreements pursuant to which each of the Company's officers and
directors, and all persons or entities who, immediately prior to the declaration

or otherwise) or dispose of any beneficial interest therein for a period of not
less than twelve (12) months following the effective date of the Registration

the effective date of the Registration Statement, the Company shall not sell or
offer for sale any of its securities without the prior consent of the
Representative, except pursuant to or in connection with (i) the exercise of

understandings, whether oral or written, for services in the nature of a
finder's or origination fee with respect to the sale of the Securities hereunder

respect to the Company, or any of its officers, directors, stockholders,
partners, employees or affiliates, that may affect the Underwriters'
compensation, as determined by the NASD.

listing on the American Stock Exchange (the "ASE"). 

         (y)  None of the Company, nor any of its officers, employees, agents

customer, supplier, employee or agent of a customer or supplier, or official or
employee of any governmental agency (domestic or foreign) or instrumentality of
any government

(domestic or foreign) or any political party or candidate for office 
(domestic or foreign) or other person who was, is, or may be in a position to 
help or hinder the business of the Company (or assist the Company in

the Company, or any other such person to any damage or penalty in any civil, 
criminal or governmental litigation or proceeding (domestic or foreign), (b) 
if not given in the past, might have had a material adverse effect on the 
assets, business or operations of the Company, or (c) if not continued in the 
future, might adversely affect the assets, business, financial condition or 
operations of the Company. The Company's internal accounting controls are 
sufficient to cause the Company to comply with the Foreign Corrupt Practices 
Act of 1977, as amended. 

         (z)  Except as set forth in the Prospectus, no officer, director or
stockholder of the Company, or any "affiliate" or "associate" (as these terms

foregoing persons or entities has or has had, either directly or indirectly, (i)
a material interest in any person or entity which (A) furnishes or sells
services or products which are furnished or sold or are proposed to be furnished
or sold by the Company, or (B) purchases from or sells or furnishes to the
Company any goods or services, or (ii) a material beneficial interest in any
contract or agreement to which the Company is a party or by which it may be
bound or affected, in either case of a value equal to or greater than $25,000 in
any fiscal year of the Company. Except as set forth in the Prospectus under
"Certain Transactions," there are no existing agreements, arrangements,
understandings or transactions, or proposed agreements, arrangements,
understandings or transactions, between or among the Company, and any officer,
director, or 5% or greater stockholder of the Company, or any partner, affiliate
or associate of any of the foregoing persons or entities. 

         (aa) Any certificate signed by any officer of the Company, and
delivered to the Underwriters or to Underwriters' Counsel (as defined herein)
shall be deemed a representation and warranty by the Company to the Underwriters
as to the matters covered thereby. 

         (bb) The minute books of the Company have been made available to the
Underwriters and contain a complete summary of all meetings and actions of the
directors (including committees thereof) and stockholders of the Company, since
the time of its incorporation, and reflect all transactions referred to in such
minutes accurately in all material respects. 

         (cc) Except and to the extent described in the Prospectus, no holders
of any securities of the Company or of any options, warrants or other
convertible or exchangeable securities of the Company have the right to include
any securities issued by the Company in the Registration Statement or any
registration statement to be filed by the Company or to require the Company to
file a registration statement under the Act and no person or entity holds any
anti-dilution rights with respect to any securities of the Company.

contemplated and the application of the net proceeds therefrom as described 
in the Prospectus under the caption "Use of Proceeds" will not be, an 
"investment company" or an entity "controlled" by an "investment company" as 
such terms are defined in the Investment Company Act of 1940, as amended (the 
"1940 Act"). 

         (ff) The Company maintains a system of internal accounting controls
sufficient to provide reasonable assurance that (i) transactions are executed in
accordance with management's general or specific authorizations; (ii)
transactions are recorded as necessary to permit preparations of financial
statements in conformity with generally accepted accounting principles and to
maintain accountability for assets; (iii) access to assets is permitted only in
accordance with management's general or specific authorizations; and (iv) the
recorded accountability for assets is compared with the existing assets at
reasonable intervals and appropriate action is taken with respect to any
differences. 

         (gg) The Company has entered into a warrant agreement substantially in
the form filed as Exhibit 4.2 to the Registration Statement (the "Warrant
Agreement") with American Stock Transfer and Trust Company, as Warrant Agent, in
form and substance satisfactory to the Representative, with respect to the
Redeemable Warrants. 

    2.   PURCHASE, SALE AND DELIVERY OF THE SECURITIES. 

         (a)  On the basis of the representations, warranties, covenants and
agreements herein contained, but subject to the terms and conditions herein set
forth, the Company agrees to sell to each Underwriter, and each Underwriter,
severally and not jointly, agrees to purchase from the Company at a price of 
$______ [91% of the initial public offering price per share of Common Stock]
per share of Common Stock and $_______ [91% of the initial public offering
price per Redeemable Warrant] per Redeemable Warrant, that number of Firm
Securities set forth in Schedule A opposite the name of such Underwriter,
subject to such adjustment as the Representative in its sole discretion shall
make to eliminate any sales or purchases of fractional shares, plus any
additional number of Firm Securities which such Underwriter may become obligated
to purchase pursuant to the provisions of Section 11 hereof. 

         (b)  In addition, on the basis of the representations, warranties,
covenants and agreements herein contained, but subject to the terms and
conditions herein set forth, the Company hereby grants an option to the
Underwriters, severally and not jointly, to purchase all  or  any  part  of an
additional 450,000 shares of Common Stock at a price of $ _________ per share
of Common Stock [91% of the initial public offering price per share of Common
Stock] and/or an additional 450,000 Redeemable Warrants at a price of 
$________  per Redeemable Warrant [91% of the initial public offering price per 
Redeemable Warrant]. The option granted hereby will expire forty-five (45) days 
after (i) the date the Registration Statement becomes effective, if the 
Company has elected not to rely on Rule 430A under the Regulations, or (ii) 
the date of this Agreement if the Company has elected to rely upon Rule 430A 
under the Regulations, and may be exercised in whole or in part from time to 
time only for the purpose of covering over-allotments which may be made in 
connection with the offering and distribution of the Firm Securities upon 
notice by the Representative to the Company setting forth the number of 
Option Securities as to which the several Underwriters are then 


                                      11

<PAGE>

exercising the option and the time and date of payment and delivery for any 
such Option Securities. Any such time and date of delivery (an "Option 
Closing Date") shall be determined by the Representative, but shall not be 
later than three (3) full business days after the exercise of said option, 
nor in any event prior to the Closing Date, as hereinafter defined, unless 
otherwise agreed upon by the Representative and the Company. Nothing herein 
contained shall obligate the Underwriters to make any over-allotments. No 
Option Securities shall be delivered unless the Firm Securities shall be 
simultaneously delivered or shall theretofore have been delivered as herein 
provided. 

         (c)  Payment of the purchase price for, and delivery of certificates
for, the Firm Securities shall be made at the offices of Security Capital at 520
Madison Avenue, 10th Floor, New York, New York 10022, or at such other place as
shall be agreed upon by the Representative and the Company.  Such delivery and
payment shall be made at 10:00 a.m. (New York City time) on _______________,
1998 or at such other time and date as shall be agreed upon by the
Representative and the Company, but not less than three (3) nor more than five
(5) full business days after the effective date of the Registration Statement
(such time and date of payment and delivery being herein called the "Closing
Date").  In addition, in the event that any or all of the Option Securities are
purchased by the Underwriters, payment of the purchase price for, and delivery
of certificates for, such Option Securities shall be made at the above-mentioned
office of the Representative or at such other place as shall be agreed upon by
the Representative and the Company on each Option Closing Date as specified in
the notice from the Representative to the Company relating thereto. Delivery of
the certificates for the Firm Securities and the Option Securities, if any,
shall be made to the Underwriters against payment by the Underwriters, severally
and not jointly, of the purchase price for the Firm Securities and the Option
Securities, if any, to the order of the Company for the Firm Securities and the
Option Securities, if any, by New York Clearing House funds. In the event such
option is exercised, each of the Underwriters, acting severally and not jointly,
shall purchase that proportion of the total number of Option Securities then
being purchased which the number of Firm Securities set forth in Schedule A
hereto opposite the name of such Underwriter bears to the total number of Firm
Securities, subject in each case to such adjustments as the Representative in
its discretion shall make to eliminate any sales or purchases of fractional
shares.  Certificates for the Firm Securities and the Option Securities, if any,
shall be in definitive, fully registered form, shall bear no restrictive legends
and shall be in such denominations and registered in such names as the
Underwriters may request in writing at least two (2) business days prior to the
Closing Date or the relevant Option Closing Date, as the case may be. The
certificates for the Firm Securities and the Option Securities, if any, shall be
made available to the Representative at such office or such other place as the
Representative may designate for inspection, checking and packaging no later
than 9:30 a.m. on the last business day prior to the Closing Date or the
relevant Option Closing Date, as the case may be. 

         (d)  On the Closing Date, the Company shall issue and sell to the
Representative Representative's Warrants at a purchase price of $.0001 per
warrant, which Representative's Warrants shall entitle the holders thereof to
purchase an aggregate of 300,000 shares of Common Stock and/or 300,000
Redeemable Warrants.  The Representative's Warrants shall be exercisable for a
period of four years commencing one year from the effective date of the
Registration Statement at a price equaling 120% of the respective initial public
offering price of the Shares and the


                                      12

<PAGE>

Redeemable Warrants. The Representative's Warrant Agreement and form of 
Warrant Certificate shall be substantially in the form filed as Exhibit 4.3 
to the Registration Statement. Payment for the Representative's Warrants 
shall be made on the Closing Date. 

    3.   PUBLIC OFFERING OF THE SHARES AND REDEEMABLE WARRANTS.  As soon after
the Registration Statement becomes effective as the Representative deems
advisable, the Underwriters shall make a public offering of the Shares and
Redeemable Warrants (other than to residents of or in any jurisdiction in which
qualification of the Securities is required and has not become effective) at the
price and upon the other terms set forth in the Prospectus. The Representative
may from time to time increase or decrease the public offering price after
distribution of the Shares and Redeemable Warrants has been completed to such
extent as the Representative, in its sole discretion, deems advisable. The
Underwriters may enter into one of more agreements as the Underwriters, in each
of their sole discretion, deem advisable with one or more broker-dealers who
shall act as dealers in connection with such public offering. 

    4.   COVENANTS AND AGREEMENTS OF THE COMPANY.  The Company covenants and
agrees with each of the Underwriters as follows: 

         (a)  The Company shall use its best efforts to cause the Registration
Statement and any amendments thereto to become effective as promptly as
practicable and will not at any time, whether before or after the effective date
of the Registration Statement, file any amendment to the Registration Statement
or supplement to the Prospectus or file any document under the Act or Exchange
Act before termination of the offering of the Shares and the Redeemable Warrants
by the Underwriters of which the Representative shall not previously have been
advised and furnished with a copy, or to which the Representative shall have
objected or which is not in compliance with the Act, the Exchange Act or the
Regulations. 

         (b)  As soon as the Company is advised or obtains knowledge thereof,
the Company will advise the Representative and confirm the notice in writing (i)
when the Registration Statement, as amended, becomes effective, if the
provisions of Rule 430A promulgated under the Act will be relied upon, when the
Prospectus has been filed in accordance with said Rule 430A and when any post-
effective amendment to the Registration Statement becomes effective; (ii) of the
issuance by the Commission of any stop order or of the initiation, or the
threatening, of any proceeding suspending the effectiveness of the Registration
Statement or any order preventing or suspending the use of the Preliminary
Prospectus or the Prospectus, or any amendment or supplement thereto, or the
institution of proceedings for that purpose; (iii) of the issuance by the
Commission or by any state securities commission of any proceedings for the
suspension of the qualification of any of the Securities for offering or sale in
any jurisdiction or of the initiation, or the threatening, of any proceeding for
that purpose; (iv) of the receipt of any comments from the Commission; and (v)
of any request by the Commission for any amendment to the Registration Statement
or any amendment or supplement to the Prospectus or for additional information.
If the Commission or any state securities commission shall enter a stop order or
suspend such qualification at any time, the Company will make every effort to
obtain promptly the lifting of such order. 

         (c)  The Company shall file the Prospectus (in form and substance
satisfactory to 


                                     13

<PAGE>

the Representative) or transmit the Prospectus by a means reasonably 
calculated to result in filing with the Commission pursuant to Rule 424(b)(1) 
(or, if applicable and if consented to by the Representative, pursuant to 
Rule 424(b)(4)) not later than the Commission's close of business on the 
earlier of (i) the second business day following the execution and delivery 
of this Agreement and (ii) the fifth business day after the effective date of 
the Registration Statement. 

         (d)  The Company will give the Representative notice of its intention
to file or prepare any amendment to the Registration Statement (including any
post-effective amendment) or any amendment or supplement to the Prospectus
(including any revised prospectus which the Company proposes for use by the
Underwriters in connection with the offering of the Securities which differs
from the corresponding prospectus on file at the Commission at the time the
Registration Statement becomes effective, whether or not such revised prospectus
is required to be filed pursuant to Rule 424(b) of the Regulations), and will
furnish the Representative with copies of any such amendment or supplement a
reasonable amount of time prior to such proposed filing or use, as the case may
be, and will not file any such prospectus to which the Representative or Hall
Dickler Kent Friedman & Wood, LLP ("Underwriters' Counsel") shall object. 

         (e)  The Company shall endeavor in good faith, in cooperation with the
Representative, at or prior to the time the Registration Statement becomes
effective, to qualify the Securities for offering and sale under the securities
laws of such jurisdictions as the Representative may designate to permit the
continuance of sales and dealings therein for as long as may be necessary to
complete the distribution, and shall make such applications, file such documents
and furnish such information as may be required for such purpose; provided,
however, the Company shall not be required to qualify as a foreign corporation
or file a general or limited consent to service of process in any such
jurisdiction. In each jurisdiction where such qualification shall be effected,
the Company will, unless the Representative agrees that such action is not at
the time necessary or advisable, use all reasonable efforts to file and make
such statements or reports at such times as are or may reasonably be required by
the laws of such jurisdiction to continue such qualification. 

         (f)  During the time when a prospectus relating to the Securities is
required to be delivered under the Act, the Company shall use all reasonable
efforts to comply with all requirements imposed upon it by the Act and the
Exchange Act, as now and hereafter amended and by the Regulations, as from time
to time in force, so far as necessary to permit the continuance of sales of or
dealings in the Securities in accordance with the provisions hereof and the
Prospectus, or any amendments or supplements thereto.  If at any time when a
prospectus relating to the Securities is required to be delivered under the Act,
any event shall have occurred as a result of which, in the opinion of counsel
for the Company or Underwriters' Counsel, the Prospectus, as then amended or
supplemented, includes an untrue statement of a material fact or omits to state
any material fact required to be stated therein or necessary to make the
statements therein, in the light of the circumstances under which they were
made, not misleading, or if it is necessary at any time to amend the Prospectus
to comply with the Act, the Company will notify the Representative promptly and
prepare and file with the Commission an appropriate amendment or supplement in
accordance with Section 10 of the Act, each such amendment or supplement to be
satisfactory to Underwriters' Counsel, and the Company will furnish to the
Underwriters copies of such amendment or supplement as soon as available and in
such quantities as the Underwriters may request. 


                                      14

         (g)  As soon as practicable, but in any event not later than 45 days
after the end of the 12-month period beginning on the day after the end of the
fiscal quarter of the Company during which the effective date of the
Registration Statement occurs (90 days in the event that the end of such fiscal
quarter is the end of the Company's fiscal year), the Company shall make
generally available to its security holders, in the manner specified in Rule
158(b) of the Regulations, and to the Representative, an earnings statement
which will be in the detail required by, and will otherwise comply with, the
provisions of Section 11(a) of the Act and Rule 158(a) of the Regulations, which
statement need not be audited unless required by the Act, covering a period of
at least 12 consecutive months after the effective date of the Registration
Statement. 

         (h)  During a period of five years after the date hereof, the Company
will furnish to its stockholders, as soon as practicable, annual reports
(including financial statements audited by independent public accountants) and
unaudited quarterly reports of earnings, and will deliver to the Representative:

              (i)  copies of such unaudited quarterly reports concurrently 
with furnishing such quarterly reports to its stockholders, accompanied by a 
certificate thereon by the Company's principal financial or accounting 
officer; 

             (ii)   copies of such annual reports concurrently with 
furnishing such reports to its stockholders; 

             (iii)  as soon as they are available, copies of all reports 
(financial or other) mailed to stockholders; 

             (iv)   as soon as they are available, copies of all reports and 
financial statements furnished to or filed with the Commission, the NASD or 
any securities exchange; 

             (v)    every press release and every material news item or 
article of interest to the financial community in respect of the Company, or 
its affairs, which was released or prepared by or on behalf of the Company; 
and 

             (vi)   any additional information of a public nature concerning 
the Company (and any future subsidiary) or its businesses which the 
Representative may request. 

         During such five-year period, if the Company has an active subsidiary,
the foregoing financial statements will be on a consolidated basis to the extent
that the accounts of the Company and its subsidiary(ies) are consolidated, and
will be accompanied by similar financial statements for any significant
subsidiary which is not so consolidated. 

         (i)  The Company will maintain a transfer agent and warrant agent
("Transfer Agent") and, if necessary under the jurisdiction of incorporation of
the Company, a Registrar (which may be the same entity as the Transfer Agent)
for its Common Stock and Redeemable Warrants. 


                                      15

<PAGE>

         (j)  The Company will furnish to the Representative or on the
Representative's order, without charge, at such place as the Representative may
designate, copies of each Preliminary Prospectus, the Registration Statement and
any pre-effective or post-effective amendments thereto (two of which copies will
be signed and will include all financial statements and exhibits), the
Prospectus, and all amendments and supplements thereto, including any prospectus
prepared after the effective date of the Registration Statement, in each case as
soon as available and in such quantities as the Representative may request. 

         (k)  On or before the effective date of the Registration Statement,
the Company shall provide the Representative with true original copies of duly
executed, legally binding and enforceable agreements from each of the Company's
officers and directors, and all persons or entities who, immediately prior to
the declaration of effectiveness of the Registration Statement are (a) holders
of 5% or more of the shares of Common Stock; and/or (b) holders of securities
exercisable or exchangeable for or convertible into 5% or more of the shares of
Common Stock, providing that such persons or entities shall  not, directly or
indirectly, offer, sell, grant any option for the sale or purchase of, assign,
transfer, pledge, hypothecate or otherwise encumber or dispose of any shares of
Common Stock or securities convertible into, exercisable or exchangeable for or
evidencing any right to purchase or subscribe for any shares of Common Stock
(either pursuant to Rule 144 of the Regulations or otherwise) or dispose of any
beneficial interest therein during the Lock-Up Period without the prior written
consent of the Representative and the Company (collectively, the "Lock-up
Agreements"). During the 12 month period commencing on the effective date of the
Registration Statement, the Company shall not sell or offer for sale any of its
securities without the prior consent of the Representative, except pursuant to
or in connection with (i) the exercise of options granted by the Company under a
Plan, (ii) the exercise of non-Plan options and warrants granted by the Company
prior to the date hereof and/or (iii) the issuance of shares of Common Stock in
transactions involving acquisitions by the Company of the assets or equity
ownership of unrelated business entities.  On or before the Closing Date, the
Company shall deliver instructions to the Transfer Agent authorizing it to place
appropriate legends on the certificates representing the securities subject to
the Lock-up Agreements and to place appropriate stop transfer orders on the
Company's ledgers. 

         (l)  None of the Company, nor any of its officers, directors,
stockholders, nor any of its affiliates (within the meaning of the Regulations)
will take, directly or indirectly, any action designed to, or which might in the
future reasonably be expected to cause or result in, stabilization or
manipulation of the price of any securities of the Company. 

         (m)  The Company shall apply the net proceeds from the sale of the
Securities in the manner, and subject to the conditions, set forth under "Use of
Proceeds" in the Prospectus.  No portion of the net proceeds will be used,
directly or indirectly, to acquire any securities issued by the Company. 

         (n)  The Company shall timely file all such reports, forms or other
documents as may be required from time to time, under the Act, the Exchange Act,
and the Regulations, and all such reports, forms and documents filed will comply
as to form and substance with the applicable requirements under the Act, the
Exchange Act, and the Regulations. 


                                      16

<PAGE>

         (o)  The Company shall furnish to the Representative as early as
practicable prior to each of the date hereof, the Closing Date and each Option
Closing Date, if any, but no later than two full business days prior thereto, a
copy of the latest available unaudited interim financial statements of the
Company (which in no event shall be as of a date more than 30 days prior to the

use its reasonable best efforts to maintain the ASE listing of the Common Stock
and the Redeemable Warrants to the extent outstanding. 

         (q)  As and when reasonably requested by the Representative from time
to time during the period of five years from the Closing Date, the Company shall

consolidated transfer sheets relating to the Common Stock and Redeemable
Warrants (ii) the list of holders of all of the Company's securities and (iii) a

Company shall file a Form 8-A with the Commission providing for the registration
under the Exchange Act of the Securities and (ii) but in no event more than 30
days after the effective date of the Registration Statement, in the event that

Poor's Corporation Descriptions and Moody's OTC Manual and to continue such
inclusion for a period of not less than five years. 

         (s)  The Company hereby agrees that it will not, for a period of 12
months from the effective date of the Registration Statement, adopt, propose to
adopt or otherwise permit to exist any employee, officer, director, consultant

    6.   CONDITIONS OF THE UNDERWRITERS' OBLIGATIONS.  The obligations of the
Underwriters hereunder shall be subject to the continuing accuracy of the
representations and warranties of the Company herein as of the date hereof and
as of the Closing Date and each Option Closing Date, if any, as if they had been
made on and as of the Closing Date or each Option Closing Date, as the case may

each Option Closing Date, if any, of its covenants and obligations hereunder and
to the following further conditions: 

         (a)  The Registration Statement shall have become effective not later
than 12:00 P.M., New York time, on the date of this Agreement or such later date
and time as shall be consented to in writing by the Representative, and at the
Closing Date and each Option Closing Date, if any, no stop order suspending the
effectiveness of the Registration Statement shall have been issued and no
proceedings for that purpose shall have been instituted or shall be pending or
contemplated by the Commission and any request on the part of the Commission for
additional information shall have been complied with to the reasonable
satisfaction of Underwriters' Counsel. If the Company has elected to rely upon
Rule 430A of the Regulations, the price of the Firm Securities and any
price-related information previously omitted from the effective Registration
Statement pursuant to such Rule 430A shall have been transmitted to the
Commission for filing pursuant to Rule 424(b) of the Regulations within the

the Regulations. 

         (b)  The Representative shall not have advised the Company that the
Registration Statement, or any amendment thereto, contains an untrue statement
of fact which, in the Representative's opinion, is material, or omits to state a
fact which, in the Representative's opinion, is material and is required to be
stated therein or is necessary to make the statements therein not 


                                      19

<PAGE>

misleading, or that the Prospectus, or any supplement thereto, contains an 
untrue statement of fact which, in the Representative's opinion, is material, 
or omits to state a fact which, in the Representative's opinion, is material 
and is required to be stated therein or is necessary to make the statements 
therein, in light of the circumstances under which they were made, not 
misleading. 

         (c)  On or prior to each of the Closing Date and each Option Closing
Date, if any, the Representative shall have received from Underwriters' Counsel,
such opinion or opinions with respect to the organization of the Company, the
validity of the Securities, the Registration Statement, the Prospectus and other
related matters as the Representative may request and Underwriters' Counsel
shall have received such papers and information as they request to enable them
to pass upon such matters. 

         (d)  At the Closing Date, the Underwriters shall have received the
favorable opinion of Miller & Holguin ("M&H"), counsel to the Company, dated the
Closing Date,  addressed to the Underwriters and in form and substance
satisfactory to Underwriters' Counsel, to the effect that: 

              (i)  The Company (A) has been duly organized and is validly
existing as a corporation in good standing under the laws of its jurisdiction,
(B) is duly qualified and licensed and in good standing as a foreign corporation
in each jurisdiction in which its ownership or leasing of any properties or the
character of its operations requires such qualification or licensing (except
where the failure to so qualify would not have a material adverse effect on the
business, financial condition or operations of the Company), and (C) has all
requisite corporate power and authority to own or lease its properties and
conduct its business as described in the Prospectus, and has obtained any and
all necessary authorizations, approvals, orders, licenses, certificates,
franchises and permits of and from all governmental or regulatory officials and
bodies to conduct its business as described in the Prospectus, and, to the
current actual knowledge of such counsel, has not received any notice of
proceedings relating to the revocation or modification of any such
authorization, approval, order, license, certificate, franchise, or permit
which, singly or in the aggregate, if the subject of an unfavorable decision,
ruling or finding, would materially adversely affect the business, financial
condition or operations of the Company. The disclosures in the Registration
Statement concerning the effects of federal, state and local laws, rules and
regulations on the Company's business as described in the Prospectus are correct
in all material respects and do not omit to state a fact required to be stated
therein or necessary to make the statements contained therein not misleading in
light of the circumstances in which they were made. 

              (ii) To the current actual knowledge of such counsel, except as
described in the Prospectus, the Company does not own an interest in any other
corporation, partnership, joint venture, trust or other business entity.

              (iii) The Company has a duly authorized, and issued and 
outstanding capitalization as set forth in the Prospectus, and any amendment 
or supplement thereto, under "Capitalization", and the Company is not, to the 
current actual knowledge of such counsel, a party to or bound by any 
instrument, agreement or other arrangement providing for it to issue, sell, 
transfer, purchase or redeem any capital stock, rights, warrants, options or 
other securities, except

                                      20

<PAGE>

for this Agreement, the Warrant Agreement and the Representative's Warrant 
Agreement and as described in the Prospectus.  The Securities and all other 
securities issued or issuable by the Company conform in all material respects 
to all statements with respect thereto contained in the Registration 
Statement and the Prospectus.  All issued and outstanding securities of the 
Company have been duly authorized and validly issued and are fully paid (to 
the current actual knowledge of such counsel) and non-assessable; the holders 
thereof do not have any rights of rescission with respect thereto, and are 
not subject to personal liability by reason of being such holders; and none 
of such securities were issued in violation of the preemptive rights of any 
holders of any security of the Company or any similar rights imposed by the 
Company's certificate of incorporation.  The Securities to be sold by the 
Company hereunder and under the Warrant Agreement and the Representative's 
Warrant Agreement are not and will not be subject to any preemptive or other 
similar rights of any stockholder imposed by the Company's certificate of 
incorporation or, to the current actual knowledge of such counsel, by any 
agreement or other instrument binding upon the Company, have been duly 
authorized and, when issued, paid for and delivered in accordance with the 
terms hereof and thereof, will be validly issued, fully paid and 
non-assessable and conform to the description thereof contained in the 
Prospectus; the holders thereof will not be subject to any liability solely 
as such holders; all corporate action required to be taken for the 
authorization, issuance and sale of the Securities has been duly and validly 
taken; and the certificates representing the Securities are in due and proper 
form. The Representative's Warrants and the Redeemable Warrants will, when 
issued, paid for and delivered in accordance with the terms set forth herein 
and in the Warrant Agreement and Representative's Warrant Agreement, 
constitute valid and binding obligations of the Company to issue and sell, 
upon exercise thereof and payment therefor, the number and type of securities 
of the Company called for thereby. Upon the issuance and delivery pursuant to 
this Agreement of the Firm Securities and the Option Securities and the 
Representative's Warrants to be sold by the Company, the Underwriters and the 
Representative, respectively, will acquire good title to the Firm Securities 
and the Option Securities and the Representative's Warrants free and clear of 
any pledge, lien, charge, claim, encumbrance, pledge, security interest, or 
other restriction or equity of any kind whatsoever created by or imposed 
against the Company.

              (iv) The Registration Statement is effective under the Act, and,
if applicable, filing of all pricing information has been timely made in the
appropriate form under Rule 430A of the Regulations, and no stop order
suspending the use of the Preliminary Prospectus, the Registration Statement or
Prospectus or any part of any thereof or suspending the effectiveness of the
Registration Statement has been issued and no proceedings for that purpose, to
the current actual knowledge of such counsel, have been instituted or are
pending or, to the current actual knowledge of such counsel, threatened or
contemplated under the Act.

              (v)  Each of the Preliminary Prospectus, the Registration
Statement, and the Prospectus and any amendments or supplements thereto (other
than the financial statements and other financial and statistical data included
therein, as to which no opinion need be rendered) complies as to form in all
material respects with the requirements of the Act and the Regulations. 

              (vi) To the current actual knowledge of such counsel (A) there is
not any agreement, contract or other document required by the Act to be
described in the Registration Statement and the Prospectus and filed as an
exhibit to the Registration Statement other than those 


                                      21

<PAGE>

described in the Registration Statement (or required to be filed under the 
Exchange Act if upon such filing they would be incorporated, in whole or in 
part, by reference therein) and the Prospectus and filed as an exhibit 
thereto, and the exhibits which have been filed are correct copies of the 
documents of which they purport to be copies; (B) the descriptions in the 
Registration Statement and the Prospectus and any supplement or amendment 
thereto of contracts and other documents to which the Company is a party or 
by which it is bound, including any document to which the Company is a party 
or by which it is bound, incorporated by reference into the Prospectus and 
any supplement or amendment thereto, are accurate and fairly present in all 
material respects the information required to be shown by Form S-1; (C) there 
is not pending or threatened against the Company any action, arbitration, 
suit, proceeding, inquiry, investigation, litigation, governmental or other 
proceeding (including, without limitation, those having jurisdiction over 
environmental or similar matters), domestic or foreign, pending or threatened 
against (or circumstances that may give rise to the same), or involving the 
properties or business of, the Company which (x) is required to be disclosed 
in the Registration Statement which is not so disclosed (and such proceedings 
as are summarized in the Registration Statement are accurately summarized in 
all respects), or (y) questions the validity of the capital stock of the 
Company or this Agreement, the Warrant Agreement or the Representative's 
Warrant Agreement, or of any action taken or to be taken by the Company 
pursuant to or in connection with any of the foregoing; (D) there is no 
statute or regulation or legal or governmental proceeding required to be 
described in the Prospectus which is not described as required; and (E) there 
is no action, suit or proceeding pending, or threatened, against or affecting 
the Company before any court or arbitrator or governmental body, agency or 
official (or any basis thereof known to such counsel) in which there is a 
reasonable possibility of a decision which would result in a material adverse 
change in the business, financial condition or operations of the Company, 
which would adversely affect the present or prospective ability of the 
Company to perform its obligations under this Agreement, the Warrant 
Agreement or the Representative's Warrant Agreement or which in any manner 
would draw into question the validity or enforceability of this Agreement, 
the Warrant Agreement or the Representative's Warrant Agreement.

              (vii)     The Company has full legal right, power and authority
to enter into each of this Agreement, the Warrant Agreement and the
Representative's Warrant Agreement, and to consummate the transactions provided
for therein; and each of this Agreement, the Warrant Agreement and the
Representative's Warrant Agreement has been duly authorized, executed and
delivered by the Company. Each of this Agreement, the Warrant Agreement and the
Representative's Warrant Agreement, assuming due authorization, execution and
delivery by and enforceability against each other party thereto, constitutes a
legal, valid and binding agreement of the Company enforceable against the
Company in accordance with its terms (except as such enforceability may be
limited by applicable bankruptcy, insolvency, reorganization, moratorium or
other laws of general application relating to or affecting enforcement of
creditors' rights and the application of equitable principles in any action,
legal or equitable, and except as rights to indemnity or contribution may be
limited by applicable law), and none of the Company's execution or delivery of
this Agreement, the Warrant Agreement and the Representative's Warrant
Agreement, its performance hereunder or thereunder, its consummation of the
transactions contemplated herein or therein, or the conduct of its business as
described in the Registration Statement, the Prospectus, and any amendments or
supplements thereto, conflicts with or will conflict with or results or will
result in any breach or violation of any of the terms or provisions of, or
constitutes or will constitute a default under, or 


                                      22

<PAGE>

results or will result in the creation or imposition of any lien, charge, 
claim, encumbrance, pledge, security interest, defect or other restriction or 
equity of any kind whatsoever upon, any property or assets (tangible or 
intangible) of the Company pursuant to the terms of, (A) the certificate of 
incorporation or by-laws of the Company, or (B) to the current actual 
knowledge of such counsel, any license, contract, collective bargaining 
agreement, indenture, mortgage, deed of trust, lease, voting trust agreement, 
stockholders agreement, note, loan or credit agreement or any other agreement 
or instrument to which the Company is a party or by which it is or may be 
bound or to which any of its properties or assets (tangible or intangible) is

actual knowledge of such counsel, any statute, judgment, decree, order, rule 
or regulation applicable to the Company of any arbitrator, court, regulatory 
body or administrative agency or other governmental agency or body 
(including, without limitation, those having jurisdiction over environmental 
or similar matters), domestic or foreign, having jurisdiction over the 
Company or any of its activities or properties. 

              (viii)    Except for the order of the Commission declaring the
Registration Statement to be effective, no consent, approval, authorization or
order, and no filing with, any court, regulatory body, government agency or

Firm Securities and the Option Securities pursuant to the Prospectus and the
Registration Statement, the issuance of the Representative' Warrants, the
performance of this Agreement, the Warrant Agreement and the Representative's
Warrant Agreement, and the transactions contemplated hereby and thereby.

              (ix) Except to the extent that it would not have a material
adverse effect on the business, financial condition or operations of the
Company, the Company has good and marketable title to, or valid and enforceable
leasehold estates in, all items of real and personal property stated in the

liens, charges, claims, encumbrances, pledges, security interests, defects or

to in the Prospectus and liens for taxes not yet due and payable. 

              (x)  The Company is not, to the current actual knowledge of such
counsel, in breach of, or in default under, any term or provision of any
license, contract, collective bargaining agreement, indenture, mortgage,
installment sale agreement, deed of trust, lease, voting trust agreement,
stockholders' agreement, partnership agreement, note, loan or credit agreement
or any other agreement or instrument evidencing an obligation for borrowed

<PAGE>

Company," "Business of the Company," "Management of the Company," "Beneficial
Ownership of Capital Stock," "Certain Transactions," "Description of Capital
Stock " and "Shares Eligible for Future Sale" have been reviewed by such

statutes, regulatory permits, licenses, rules or regulations or legal
conclusions, are correct in all material respects.

              (xii)     The Securities have been accepted for listing on the

              (xiii)    To the current actual knowledge of such counsel, no

or, if filed, to include any security in such registration statement. 

              (xiv)     To the current actual knowledge of such counsel, except
as described in the Prospectus, there are no claims, payments, issuances,
arrangements or understandings for services in the nature of a finder's or
origination fee with respect to the sale of the Securities hereunder or
financial consulting arrangements or any other arrangements, agreements,
understandings, payments or issuances that may affect the Underwriters'
compensation, as determined by the NASD. 

              (xv) Assuming due authorization, execution and delivery by the
parties thereto, the Lock-up Agreements in the form of Exhibit A annexed hereto
are legal, valid and binding obligations of the parties thereto, enforceable
against such parties in accordance with their respective terms (except as such

reorganization, moratorium or other laws of general application relating to or
affecting enforcement of creditors' rights and the application of equitable
principles in any action, legal or equitable, and except as rights to indemnity
or contribution may be limited by applicable law). 

              (xvi)     To the current actual knowledge of such counsel, except
as described in the Prospectus, the Company does not (A) maintain, sponsor or
contribute to any ERISA Plans, (B) maintain or contribute, now or at any time
previously, to a defined benefit plan, as defined in Section 3(35) of ERISA, and
(C) has ever completely or partially withdrawn from a "multiemployer plan". 

              (xvii)    The Company shall not, solely as a result of the offer
and sale of the Securities as described in the Prospectus, be deemed to be an
"Investment Company," pursuant to and as defined under the Investment Company
Act of 1940. 

    Such counsel shall state that such counsel has participated in conferences
with officers and other representatives of the Company, and representatives of
the independent public accountants for the Company, at which conferences such
counsel made inquiries of such officers, representatives and accountants and
discussed the contents of the Preliminary Prospectus, the Registration
Statement, the Prospectus, and related matters and, although such counsel is not
passing upon and does not assume any responsibility for the accuracy,
completeness or fairness of the statements contained in the Preliminary
Prospectus, the Registration Statement or the Prospectus, on the basis of the


                                      24

<PAGE>

foregoing, no facts have come to the attention of such counsel which lead them
to believe that either the Registration Statement or any amendment thereto, at
the time such Registration Statement or amendment became effective, or the
Preliminary Prospectus or Prospectus or amendment or supplement thereto as of
the date of such opinion, contained any untrue statement of a material fact or
omitted to state a material fact required to be stated therein or necessary to
make the statements therein, in light of the circumstances in which they were
made, not misleading(it being understood that such counsel need express no
opinion with respect to the financial statements and schedules and other
financial and statistical data included in the Preliminary Prospectus, the
Registration Statement and the Prospectus). Such counsel shall further state
that its opinions may be relied upon by Underwriters' Counsel in rendering its
opinion to the Underwriters. 

    In rendering such opinion, such counsel may rely (A) as to matters
involving the application of laws other than the laws of the United States and
jurisdictions in which they are admitted, to the extent such counsel deems
proper and to the extent specified in such opinion, if at all, upon an opinion
or opinions (in form and substance satisfactory to Underwriters' Counsel) of
other counsel acceptable to Underwriters' Counsel, familiar with the applicable
laws; (B) as to matters of fact, to the extent they deem proper, on certificates
and written statements of responsible officers of the Company and certificates
or other written statements of officers of departments of various jurisdictions
having custody of documents respecting the corporate existence or good standing
of the Company, provided that copies of any such statements or certificates
shall be delivered to Underwriters' Counsel if requested. The opinion of such
counsel for the Company shall state that the opinion of any such other counsel
is in form satisfactory to such counsel and that the Representative,
Underwriters' Counsel and they are each justified in relying thereon.  Such
opinion may state that whenever a statement therein is qualified to such
counsel's current actual knowledge, it is intended to indicate that, during the
course of such counsel's representation of the Company in connection with the
offer and sale of the Securities, no information that would give such counsel
awareness of the inaccuracy of such statement has come to the attention of those
attorneys in the firm who have rendered legal services in connection therewith.
Any opinion of counsel for the Company shall not state that it is to be governed
or qualified by, or that it is otherwise subject to, any treatise, written
policy or other document relating to legal opinions, including, without
limitation, the Legal Opinion Accord of the ABA Section of Business Law (1991)
or any comparable state accord. 

         (e)  At each Option Closing Date, if any, the Underwriters shall have
received the favorable opinion of M&H dated such Option Closing Date, addressed
to the Underwriters and in form and substance satisfactory to Underwriters'
Counsel, confirming as of such Option Closing Date the statements made by M&H in
its opinion delivered on the Closing Date. 

         (f)  On or prior to the Closing Date and each Option Closing Date, if
any, Underwriters' Counsel shall have been furnished such documents,
certificates and opinions as they may reasonably require for the purpose of
enabling them to review or pass upon the matters referred to in subsection (c)
of this Section 6, or in order to evidence the accuracy, completeness or
satisfaction of any of the representations, warranties or covenants of the
Company. 

         (g)  As of the Closing Date and each Option Closing Date, if any, (i)
there shall have been no material adverse 


                                      25

<PAGE>

change in the business, financial condition or operations of the Company, 
whether or not in the ordinary course of business, from the latest dates as 
of which such condition is set forth in the Registration Statement and 
Prospectus; (ii) there shall have been no transaction, not in the ordinary 
course of business, entered into by the Company, from the latest date as of 
which the financial condition of the Company is set forth in the Registration 
Statement and Prospectus which is adverse to the Company; (iii) the Company 
shall not be in default under any provision of any instrument relating to any 
outstanding indebtedness of the Company which default could have a material 
adverse effect upon the business, operations or financial condition of the 
Company; (iv) the Company shall not have issued any securities (other than 
the Securities) or declared or paid any dividend or made any distribution in 
respect of its capital stock of any class and there shall not have been any 
change in the capital stock or any material change in the debt (long or short 
term) or liabilities or obligations of the Company (contingent or otherwise), 
in each case, since the date hereof; (v) no material amount of the assets of 
the Company shall be pledged or mortgaged, except as set forth in the 
Registration Statement and Prospectus; (vi) no action, suit or proceeding, at 
law or in equity, shall be pending or threatened (or circumstances giving 
rise to same) against the Company, or affecting any of its properties or 
business before or by any court or federal, state or foreign commission, 
board or other administrative agency wherein an unfavorable decision, ruling 
or finding may adversely affect the business, operations, earnings, position, 
value, properties, results of operations, prospects or financial condition or 
income of the Company; and (vii) no stop order relating to the offer and sale 
of the Securities shall be in effect under the Act and no proceedings 
therefor shall be pending, threatened or contemplated by the Commission. 

         (h)  At the Closing Date and each Option Closing Date, if any, the
Underwriters shall have received a certificate of the Company signed by the
principal executive officer and by the principal financial or principal
accounting officer of the Company, dated the Closing Date or Option Closing
Date, as the case may be, to the effect that each of such persons has carefully
examined the Registration Statement, the Prospectus and this Agreement, and
that: 

              (i)  The representations and warranties of the Company in this
Agreement are true and correct, as if made on and as of the Closing Date or the
Option Closing Date, as the case may be, and the Company has complied in all
material respects with all agreements and covenants and satisfied all conditions
contained in this Agreement on its part to be complied with or satisfied at or
prior to such Closing Date or Option Closing Date, as the case may be; 

              (ii) No stop order suspending the effectiveness of the
Registration Statement or any part thereof has been issued, and no proceedings
for that purpose have been instituted  or are pending or, to the best of each of
such person's knowledge, are contemplated or threatened under the Act; 

              (iii) The Registration Statement and the Prospectus and, if 
any, each amendment and each supplement thereto, contain all statements and 
information required to be included therein, and none of the Registration 
Statement, the Prospectus nor any amendment or supplement thereto includes 
any untrue statement of a material fact or omits to state any material fact 
required to be stated therein or necessary to make the statements therein not 
misleading and neither the Preliminary Prospectus or any supplement thereto 
included any untrue statement of a material 

                                      26

<PAGE>

fact or omitted to state any material fact required to be stated therein or 
necessary to make the statements therein, in light of the circumstances under 
which they were made, not misleading; and 

              (iv) Subsequent to the respective dates as of which information
is given in the Registration Statement and the Prospectus, (A) the Company has
not incurred up to and including the Closing Date or the Option Closing Date, as
the case may be, other than in the ordinary course of its business, any material
liabilities or obligations, direct or contingent; (B) the Company has not paid
or declared any dividends or other distributions on its capital stock; (C) the
Company has not entered into any transactions not in the ordinary course of

the short-term borrowings in the ordinary course of business) of the Company;
(E) the Company has not sustained any material loss or damage to its properties
or assets, whether or not insured; (F) there is no litigation which is pending
or threatened (or circumstances giving rise to same) against the Company or any
affiliated party which is required to be set forth in an amended or supplemented
Prospectus which has not been set forth; and (G) there has occurred no event
required to be set forth in an amended or supplemented Prospectus which has not
been so set forth. 

References to the Registration Statement and the Prospectus in this subsection
(h) are to such documents as amended and supplemented at the date of such
certificate. 

         (i)  By the Closing Date, the Underwriters will have received
clearance from the NASD as to the amount of compensation allowable or payable to
the Underwriters, as described in the Registration Statement. 

         (j)  At the time this Agreement is executed, the Underwriters shall
have received "cold comfort" letters, dated such date, addressed to the
Underwriters in form and substance customary for initial public offerings of
securities, and satisfactory (including the non-material nature of the changes
or decreases, if any, referred to in clause (iii) below) in all respects to the
Underwriters and Underwriters' Counsel, from (i) Ernst & Young LLP addressing
the matters set forth in sub-sections (i) - (vi) hereof as they relate to the
Company's financial statements and disclosures for the year ended December 31,
1997 and any interim period set forth in the Prospectus which are contained in
the Prospectus; and (ii) from BDO Seidman LLP addressing the matters set forth
in sub-sections (i) - (vi) hereof as they relate to the Company's financial
statements and disclosures for the two years ended December 31, 1996 which are
contained in the Prospectus: 

              (i)  confirming that they are independent certified public
accountants with respect to the Company within the meaning of the Act and the
applicable Regulations; 

              (ii) stating that it is their opinion that the financial
statements and supporting schedules of the Company included in the Registration
Statement comply as to form in all material respects with the applicable
accounting requirements of the Act and the Regulations thereunder and that the
Representative may rely upon the opinion of Ernst & Young LLP or BDO Seidman
LLP, as the case may be, with respect to the financial statements and supporting
schedules included in the Registration Statement; 


                                      27

<PAGE>

              (iii)     stating that, on the basis of a limited review which
included a reading of the latest available unaudited interim financial
statements of the Company, a reading of the latest available minutes of the
stockholders and board of directors and the various committees of the board of
directors of the Company, consultations with officers and other employees of the
Company responsible for financial and accounting matters and other specified
procedures and inquiries, nothing has come to their attention which would lead
them to believe that (A) the unaudited financial statements and supporting
schedules of the Company included in the Registration Statement do not comply as
to form in all material respects with the applicable accounting requirements of
the Act and the Regulations or are not fairly presented in conformity with
generally accepted accounting principles applied on a basis substantially
consistent with that of the audited financial statements of the Company included
in the Registration Statement, or (B) at a specified date not more than five
days prior to the effective date of the Registration Statement, there has been
any change in the capital stock or long-term debt of the Company, or any
decrease in the stockholders' equity or net current assets or net assets of the
Company as compared with amounts shown in the December 31, 1997 balance sheet
included in the Registration Statement, other than as set forth in or
contemplated by the Registration Statement, or, if there was any change or
decrease, setting forth the amount of such change or decrease, and (C) during
the period from December 31, 1997 to a specified date not more than five days
prior to the effective date of the Registration Statement, there was any
decrease in net revenues, net earnings or net earnings per common share of the
Company, in each case as compared with the corresponding period from December
31, 1996, other than as set forth in or contemplated by the Registration
Statement, or, if there was any such decrease, setting forth the amount of such
decrease; 

              (iv) setting forth, at a date not later than five days prior to
the date of the Registration Statement, the total amount of liabilities of the
Company (including a break-down of commercial paper and notes payable to banks);

              (v)  stating that they have compared specific dollar amounts,
numbers of shares, percentages of revenues and earnings, statements and other
financial information pertaining to the Company set forth in the Prospectus in
each case to the extent that such amounts, numbers, percentages, statements and
information may be derived from the general accounting records, including work
sheets, of the Company and excluding any questions requiring an interpretation
by legal counsel, with the results obtained from the application of specified
readings, inquiries and other appropriate procedures (which procedures do not
constitute an examination in accordance with generally accepted auditing
standards) set forth in the letter and found them to be in agreement; and

              (vi) statements as to such other matters incident to the
transaction contemplated hereby as the Representative may reasonably request. 

         (k)  At the Closing Date and each Option Closing Date, if any, the
Underwriters shall have received from each of Ernst & Young LLP and BDO Seidman
LLP a letter, dated as of the Closing Date or the Option Closing Date, as the
case may be, to the effect that they reaffirm that statements made in the
letters respectively furnished by them pursuant to subsection (j) of this
Section, except that the specified date referred to shall be a date not more
than five days prior to the Closing Date or the Option Closing Date, as the case
may be, and, if the Company has elected to rely 


                                      28

<PAGE>

on Rule 430A of the Regulations, to the further effect that they have carried 
out procedures as specified in clause (v) of subsection (j) of this Section 
with respect to certain amounts, percentages and financial information as 
specified by the Representative and deemed to be a part of the Registration 
Statement pursuant to Rule 430A(b) and have found such amounts, percentages 
and financial information to be in agreement with the records specified in 
such clause (v). 

         (l)  On each of the Closing Date and each Option Closing Date, if any,
there shall have been duly tendered to the Representative for the several
Underwriters' accounts the appropriate number of Securities. 

         (m)  No order suspending the sale of the Securities in any
jurisdiction designated by the Representative pursuant to subsection (e) of
Section 4 hereof shall have been issued on either the Closing Date or the Option
Closing Date, if any, and no proceedings for that purpose shall have been
instituted or shall be contemplated. 

         (n)  On or before the Closing Date, the Company shall have executed
and delivered to the Representative, (i) the Representative's Warrant Agreement
substantially in the form filed as Exhibit 4.3 to the Registration Statement, in
final form and substance satisfactory to the Representative, and (ii) the
Representative's Warrants in such denominations and to such designees as shall
have been provided to the Company. 

         (o)  On or before the Closing Date, the Firm Securities and Option
Securities shall have been duly approved for listing on the ASE, subject to
official notice of issuance. 

         (p)  On or before the Closing Date, there shall have been delivered to
the  Representative all of the Lock-up Agreements, in form and substance
satisfactory to Underwriters' Counsel. 

         (q)  On or before the Closing Date, the Company shall have executed
and delivered to the Representative and the Transfer Agent the Warrant Agreement
substantially in the form filed as Exhibit 4.2 the Registration Statement, in
final form and substance satisfactory to the Representative. 

If any condition to the Underwriters' obligations hereunder to be fulfilled
prior to or at the Closing Date or the relevant Option Closing Date, as the case
may be, is not so fulfilled, the Representative may terminate this Agreement or,
if the Representative so elects, it may waive any such conditions which have not
been fulfilled or extend the time for their fulfillment. 

    7.   INDEMNIFICATION. 

         (a)  The Company agrees to indemnify and hold harmless each of the
Underwriters (for purposes of this Section 7 "Underwriter" shall include the
officers, directors, partners, employees, agents and counsel of an Underwriter,
including specifically each person who may be substituted for an Underwriter as
provided in Section 11 hereof), and each person, if any, who controls the
Underwriter ("controlling person") within the meaning of Section 15 of the Act
or 


                                      29

<PAGE>

Section 20(a) of the Exchange Act, from and against any and all losses,
claims, damages, expenses or liabilities, joint or several (and actions,
proceedings, investigations, inquiries, suits and litigation in respect
thereof), whatsoever (including but not limited to any and all expenses
whatsoever reasonably incurred in investigating, preparing or defending against
any such claim, action, proceeding, investigation, inquiry, suit or litigation,
commenced or threatened, or any claim whatsoever), as such are incurred, to
which the Underwriter or such controlling person may become subject under the
Act, the Exchange Act or any other statute or at common law or otherwise or
under the laws of foreign countries, arising out of or based upon (A) any untrue
statement or alleged untrue statement of a material fact contained (i) in any
Preliminary Prospectus, the Registration Statement or the Prospectus (as from
time to time amended and supplemented); (ii) in any post-effective amendment or
amendments or any new registration statement and prospectus in which is included
securities of the Company issued or issuable upon exercise of the Securities; or
(iii) in any application or other document or written communication (in this
Section 7 collectively called "application") executed by the Company or based
upon written information furnished by the Company in any jurisdiction in order
to qualify the Securities under the securities laws thereof or filed with the
Commission, any state securities commission or agency, ASE or any other
securities exchange; (B) the omission or alleged omission therefrom of a
material fact required to be stated therein or necessary to make the statements
therein, in the light of the circumstances under which they were made, not
misleading; or (C) any breach of any representation, warranty, covenant or
agreement of the Company contained herein or in any certificate by or on behalf
of the Company or any of its officers delivered pursuant hereto, unless, in the
case of clause (A) or (B) above, such statement or omission was made in reliance
upon and in strict conformity with written information furnished to the Company
with respect to any Underwriter by or on behalf of such Underwriter expressly
for use in any Preliminary Prospectus, the Registration Statement or Prospectus,
or any amendment thereof or supplement thereto, or in any application, as the
case may be. 

The indemnity agreement in this subsection (a) shall be in addition to any
liability which the Company may have at common law or otherwise. 

         (b)  Each of the Underwriters agrees severally, but not jointly, to
indemnify and hold harmless the Company, each of its directors, each of its
officers who has signed the Registration Statement, and each other person, if
any, who controls the Company within the meaning of the Act, to the same extent
as the foregoing indemnity from the Company to the Underwriters but only with
respect to statements or omissions, if any, made in any Preliminary Prospectus,
the Registration Statement or Prospectus or any amendment thereof or supplement
thereto or in any application made in reliance upon, and in strict conformity
with, written information furnished to the Company with respect to any
Underwriter by such Underwriter expressly for use in such Preliminary
Prospectus, the Registration Statement or Prospectus or any amendment thereof or
supplement thereto or in any such application, provided that such written
information or omissions only pertain to disclosures in the Preliminary
Prospectus, the Registration Statement or Prospectus directly relating to the
transactions effected by the Underwriters in connection with this Offering. The
Company acknowledges that the statements with respect to the public offering of
the Firm Securities and the Option Securities set forth under the heading
"Underwriting" and the stabilization legend in the Prospectus and the last
sentence of the front cover page of the Prospectus have been furnished by the
Underwriters expressly for use therein and constitute the only information
furnished in writing 


                                      30

<PAGE>

by or on behalf of the Underwriters for inclusion in the Prospectus. 

         (c)  Promptly after receipt by an indemnified party under this Section
7 of notice of the commencement of any claim, action, suit, investigation,
inquiry, proceeding or litigation, such indemnified party shall, if a claim in
respect thereof is to be made against one or more indemnifying parties under
this Section 7, notify each party against whom indemnification is to be sought
in writing of the commencement thereof (but the failure so to notify an
indemnifying party shall not relieve it from any liability which it may have
under this Section 7 except to the extent that it has been prejudiced in any
material respect by such failure or from any liability which it may have
otherwise). In case any such claim, action, suit, investigation, inquiry,
proceeding or litigation is brought against any indemnified party, and it
notifies an indemnifying party or parties of the commencement thereof, the
indemnifying party or parties will be entitled to participate therein, and to
the extent it may elect by written notice delivered to the indemnified party
promptly after receiving the aforesaid notice from such indemnified party, to
assume the defense thereof with counsel reasonably satisfactory to such
indemnified party. Notwithstanding the foregoing, the indemnified party or
parties shall have the right to employ its or their own counsel in any such case
but the fees and expenses of such counsel shall be at the expense of such
indemnified party or parties unless (i) the employment of such counsel shall
have been authorized in writing by the indemnifying parties in connection with
the defense thereof at the expense of the indemnifying party, (ii) the
indemnifying parties shall not have employed counsel reasonably satisfactory to
such indemnified party to have charge of the defense thereof within a reasonable
time after notice of commencement thereof, or (iii) such indemnified party or
parties shall have reasonably concluded that there may be defenses available to
it or them which are different from or additional to those available to one or
all of the indemnifying parties (in which case the indemnifying parties shall
not have the right to direct the defense thereof on behalf of the indemnified
party or parties), in any of which events such fees and expenses of one
additional counsel shall be borne by the indemnifying parties. In no event shall
the indemnifying parties be liable for fees and expenses of more than one
counsel (in addition to any local counsel) separate from their own counsel for
all indemnified parties in connection with any one claim, action, suit,
investigation, inquiry, proceeding or litigation or separate but similar or
related claims, actions, suits, investigations, inquiries, proceedings or
litigation in the same jurisdiction arising out of the same general allegations
or circumstances.  Anything in this Section 7 to the contrary notwithstanding,
an indemnifying party shall not be liable for any settlement of any claim,
action, suit, investigation, inquiry, proceeding or litigation effected without
its written consent; provided, however, that such consent was not unreasonably
withheld.  An indemnifying party will not, without the prior written consent of
the indemnified parties, settle, compromise or consent to the entry of any
judgment with respect to any pending or threatened claim, action, suit,
investigation, inquiry, proceeding or litigation in respect of which
indemnification or contribution may be sought hereunder (whether or not the
indemnified parties are actual or potential parties to such claim, action, suit,
investigation, inquiry, proceeding or litigation), unless such settlement,
compromise or consent (i) includes an unconditional release of each indemnified
party from all liability arising out of such claim, action, suit, investigation,
inquiry, proceeding or litigation and (ii) does not include a statement as to or
an admission of fault, culpability or a failure to act by or on behalf of any
indemnified party. 

         (d)  In order to provide for just and equitable contribution in any
case in which 


                                      31

<PAGE>

(i) an indemnified party makes claim for indemnification pursuant to this 
Section 7, but it is judicially determined (by the entry of a final judgment 
or decree by a court of competent jurisdiction and the expiration of time to 
appeal or the denial of the last right of appeal) that such indemnification 
may not be enforced in such case notwithstanding the fact that the express 
provisions of this Section 7 provide for indemnification in such case, or 
(ii) contribution under the Act may be required on the part of any 
indemnified party, then each indemnifying party shall contribute to the 
amount paid as a result of such losses, claims, damages, expenses or 
liabilities (or actions in respect thereof) (A) in such proportion as is 
appropriate to reflect the relative benefits received by each of the 
contributing parties, on the one hand, and the party to be indemnified on the 
other hand, from the offering of the Firm Securities and the Option 
Securities or (B) if the allocation provided by clause (A) above is not 
permitted by applicable law, in such proportion as is appropriate to reflect 
not only the relative benefits referred to in clause (i) above but also the 
relative fault of each of the contributing parties, on the one hand, and the 
party to be indemnified, on the other hand, in connection with the statements 
or omissions that resulted in such losses, claims, damages, expenses or 
liabilities, as well as any other relevant equitable considerations. In any 
case where the Company is the contributing party and the Underwriters are the 
indemnified party, the relative benefits received by the Company on the one 
hand, and the Underwriters, on the other, shall be deemed to be in the same 
proportion as the total net proceeds from the offering of the Firm Securities 
and the Option Securities (before deducting expenses) bear to the total 
underwriting discounts received by the Underwriters hereunder, in each case 
as set forth in the table on the Cover Page of the Prospectus. Relative fault 
shall be determined by reference to, among other things, whether the untrue 
or alleged untrue statement of a material fact or the omission or alleged 
omission to state a material fact relates to information supplied by the 
Company, or by the Underwriters, and the parties' relative intent, knowledge, 
access to information and opportunity to correct or prevent such untrue 
statement or omission. The amount paid or payable by an indemnified party as 
a result of the losses, claims, damages, expenses or liabilities (or actions 
in respect thereof) referred to above in this subsection (d) shall be deemed 
to include any legal or other expenses reasonably incurred by such 
indemnified party in connection with investigating or defending any such 
action or claim. Notwithstanding the provisions of this subsection (d), the 
Underwriters shall not be required to contribute any amount in excess of the 
underwriting discount applicable to the Firm Securities and the Option 
Securities purchased by the Underwriters hereunder. No person guilty of 
fraudulent misrepresentation (within the meaning of Section 11(f) of the Act) 
shall be entitled to contribution from any person who was not guilty of such 
fraudulent misrepresentation. For purposes of this Section 7, each person, if 
any, who controls the Company or the Underwriter within the meaning of the 
Act, each officer of the Company who has signed the Registration Statement, 
and each director of the Company shall have the same rights to contribution 
as the Company or the Underwriter, as the case may be, subject in each case 
to this subsection (d). Any party entitled to contribution will, promptly 
after receipt of notice of commencement of any action, suit or proceeding 
against such party in respect to which a claim for contribution may be made 
against another party or parties under this subsection (d), notify such party 
or parties from whom contribution may be sought, but the omission so to 
notify such party or parties shall not relieve the party or parties from whom 
contribution may be sought from any obligation it or they may have hereunder 
or otherwise than under this subsection (d), or to the extent that such party 
or parties were not adversely affected by such omission. The contribution 
agreement set forth above shall be in addition to any liabilities which any 
indemnifying party may have at common law or otherwise.

    8.   REPRESENTATIONS AND AGREEMENTS TO SURVIVE DELIVERY.  All 
representations, warranties and agreements contained in this Agreement or 
contained in certificates of officers of the Company submitted pursuant 
hereto, shall be deemed to be representations, warranties and agreements at 
the Closing Date and the Option Closing Date, as the case may be, and such 
representations, warranties and agreements of the Company and the indemnity 
and contribution agreements contained in Section 7 hereof, shall remain 
operative and in full force and effect regardless of any investigation made 
by or on behalf of any Underwriter, the Company, any controlling person of 
any Underwriter or the Company, and shall survive termination of this 
Agreement or the issuance and delivery of the Securities to the Underwriters 
and the Representative, as the case may be. 

    9.   EFFECTIVE DATE.  This Agreement shall become effective at 10:00 a.m.,
New York City time, on the next full business day following the date hereof, or
at such earlier time after the Registration Statement becomes effective as the
Representative, in its discretion, shall release the Securities for sale to the
public; provided, however, that the provisions of Sections 5, 7 and 10 of this
Agreement shall at all times be effective.  For purposes of this Section 9, the
Securities to be purchased hereunder shall be deemed to have been so released
upon the earlier of dispatch by the Representative of telegrams to securities
dealers releasing such securities for offering or the release by the
Representative for publication of the first newspaper advertisement which is
subsequently published relating to the Securities. 

    10.  TERMINATION. 

         (a)  Subject to subsection (b) of this Section 10, the Representative
shall have the right to terminate this Agreement, (i) if any domestic or
international event or act or occurrence has materially adversely disrupted, or
in the Representative's opinion will in the immediate future materially
adversely disrupt, the financial markets; or (ii) if any material adverse change
in the financial markets shall have occurred; or (iii) if trading generally
shall have been suspended or materially limited on or by, as the case may be,
any of the New York Stock Exchange, the American Stock Exchange, the Nasdaq
Stock Market, the Boston Stock Exchange, the Commission or any governmental
authority having jurisdiction over such matters; or (iv) if trading of any of
the securities of the Company shall have been suspended, or any of the
securities of the Company shall have been delisted, on any exchange or in any
over-the-counter market; or (v) if the United States shall have become involved
in a war or major hostilities, or if there shall have been an escalation in an
existing war or major hostilities or a national emergency shall have been
declared in the United States; or (vi) if a banking moratorium has been declared
by a state or federal authority; or (vii) if a moratorium in U.S. foreign
exchange trading has been declared; or (viii) if the Company shall have
sustained a loss material or substantial to the Company by fire, flood,
accident, hurricane, earthquake, theft, sabotage or other calamity or malicious
act which, whether or not such loss shall have been insured, will, in the
Representative's opinion, make it inadvisable to proceed with the offering, sale
and/or delivery of the Securities; or (ix) if there shall have been such a
material adverse change in the conditions or prospects of the Company, or such
material adverse change in the general market, political or economic conditions,
in the United States or elsewhere, that, in each case, in the Representative's
judgment, would make it inadvisable to proceed with the offering, sale and/or
delivery of the Securities or (x) if either Dr. Jacob Y. Terner or Dr. Gregg A.
DeNicola shall no longer serve the Company in their respective present
capacities. 


                                      33

<PAGE>

         (b)  If this Agreement is terminated by the Representative in
accordance with the provisions of Section 10(a) the Company shall promptly
reimburse and indemnify the Representative for all of its actual out-of-pocket
expenses, including the fees and disbursements of counsel for the Underwriters
(less amounts previously paid pursuant to Section 5(c) above). Notwithstanding
any contrary provision contained in this Agreement, if this Agreement shall not
be carried out within the time specified herein, or any extension thereof
granted by the Representative, by reason of any failure on the part of the
Company to perform any undertaking or satisfy any condition of this Agreement by
it to be performed or satisfied (including, without limitation, pursuant to
Section 6 or Section 12) then, the Company shall promptly reimburse and
indemnify the Representative for all of its actual out-of-pocket expenses,
including the fees and disbursements of counsel for the Underwriters (less
amounts previously paid pursuant to Section 5(c) above). In addition, the
Company shall remain liable for all Blue Sky counsel fees and disbursements,
expenses and filing fees. Notwithstanding any contrary provision contained in
this Agreement, any election hereunder or any termination of this Agreement
(including, without limitation, pursuant to Sections 6, 10, 11 and 12 hereof),
and whether or not this Agreement is otherwise carried out, the provisions of
Section 5 and Section 7 shall not be in any way affected by such election or
termination or failure to carry out the terms of this Agreement or any part
hereof. 

    11.  SUBSTITUTION OF THE UNDERWRITERS.  If one or more of the Underwriters
shall fail (otherwise than for a reason sufficient to justify the termination of
this Agreement under the provisions of Section 6, Section 10 or Section 12
hereof) to purchase the Securities which it or they are obligated to purchase on
such date under this Agreement (the "Defaulted Securities"), the Representative
shall have the right, within 24 hours thereafter, to make arrangement for one or
more of the non-defaulting Underwriters, or any other underwriters, to purchase
all, but not less than all, of the Defaulted Securities in such amounts as may
be agreed upon and upon the terms herein set forth; if, however, the
Representative shall not have completed such arrangements within such 24-hour
period, then: 

         (a)  if the number of Defaulted Securities does not exceed 10% of the
total number of Firm Securities to be purchased on such date, the non-
defaulting Underwriters shall be obligated to purchase the full amount thereof
in the proportions that their respective underwriting obligations hereunder bear
to the underwriting obligations of all non-defaulting Underwriters, or 

         (b)  if the number of Defaulted Securities exceeds 10% of the total
number of Firm Securities, this Agreement shall terminate without liability on
the part of any non-defaulting Underwriters (or, if such default shall occur
with respect to any Option Securities to be purchased on an Option Closing Date,
the Underwriters may at the Representative's option, by notice from the
Representative to the Company, terminate the Underwriters' obligation to
purchase Option Securities from the Company on such date). 

No action taken pursuant to this Section 11 shall relieve any defaulting
Underwriter from liability in respect of any default by such Underwriter under
this Agreement. 

In the event of any such default which does not result in a termination of this
Agreement, the Representative shall have the right to postpone the Closing Date
for a period not exceeding seven 


                                       34

<PAGE>

(7) business days in order to effect any required changes in the Registration 
Statement or Prospectus or in any other documents or arrangements. 

    12.  DEFAULT BY THE COMPANY.  If the Company shall fail at the Closing Date
or at any Option Closing Date, as applicable, to sell and deliver the number of
Securities which it is obligated to sell hereunder on such date, then this
Agreement shall terminate (or, if such default shall occur with respect to any
Option Securities to be purchased on an Option Closing Date, the Underwriters
may at the Representative's option, by notice from the Representative to the
Company, terminate the Underwriters' obligation to purchase Option Securities
from the Company on such date) without any liability on the part of any non-
defaulting party other than pursuant to Section 5, Section 7 and Section 10
hereof. No action taken pursuant to this Section 12 shall relieve the Company
from liability, if any, in respect of such default. 

    13.  NOTICES.  All notices and communications hereunder, except as herein
otherwise specifically provided, shall be in writing and shall be deemed to have
been duly given if mailed or transmitted by any standard form of

Security Capital Trading, Inc.

New York, New York 10022


Gentlemen:


     The undersigned understands that Security Capital Trading, Inc. (the
"Representative") is considering acting as Representative for an initial public
offering (the "Offering") of securities of Prospect Medical Holdings, Inc., a
Delaware corporation (the "Company"), pursuant to a registration statement on
Form S-1 (the "Registration Statement") filed with the Securities and Exchange
Commission (the "Commission").

     The Representative has informed the Company that the Representative's
obligation to execute an underwriting agreement with respect to the Offering,
and to purchase the securities which the Company will be offering to the public,
will be conditioned upon the Company's receipt of agreements from all persons or
entities who, immediately prior to the declaration of effectiveness of the
Registration Statement are (a) holders of 5% or more of the shares of the
Company's common stock, par value $.01 per share (the "Common Stock"); and/or
(b) holders of securities exercisable or exchangeable for or convertible into 5%
or more of the shares of Common Stock, regarding the imposition of restrictions
on the sale or other disposition of their respective securities.

     In consideration of the foregoing, and for other good and valuable
consideration, the receipt and sufficiency of which are hereby acknowledged, the
undersigned agrees that the undersigned will not, for a period of 12 months
following the date the Registration Statement is declared effective by the
Commission, without the prior written consent of the Company and the
Representative, directly or indirectly, offer, sell, transfer, pledge, assign,
hypothecate or otherwise encumber any of the shares of Common Stock or
securities exercisable or exchangeable for or convertible into shares of Common
Stock ("Derivative Securities") held by the undersigned, or otherwise dispose of
any interest therein under Rule 144 promulgated by the Commission or otherwise,
except as to transfers by gift or under the laws of descent and distribution
when the donee or transferee enters into an agreement of like tenor herewith.

                                      THE MERGER

     2.1  EFFECTIVE TIME OF THE MERGER.  Subject to the provisions of this
Agreement and the prior filing with the Delaware Secretary of State of a
Certificate of Amendment of Certificate of Incorporation increasing the number
of authorized shares of Med-Search Common from 29,000,000 to 250,000,000, a
Certificate of Merger shall be duly prepared, executed and acknowledged by the
Surviving Corporation (as defined in Section 2.2) and thereafter delivered to
the Secretary of State of the State of Delaware, for filing, in accordance with
the Delaware General Corporation Law as soon as practicable on or after the
Closing Date (as defined in Article 8 of this Agreement).  The Merger shall
become effective upon the filing of the Certificate of Merger with the Delaware
Secretary of State or such time thereafter as is provided by the Certificate of
Merger (the "Effective Time").

     2.2  EFFECTS OF THE MERGER.  At the Effective Time, (a) MS Acquisition
Corporation shall be merged with and into Prospect Medical Systems, which shall
be the surviving corporation (the "Surviving Corporation"), and the separate
existence of MS Acquisition Corporation shall cease, (b) the Certificate of
Incorporation of Prospect Medical Systems immediately prior to the Effective
Time shall be the Certificate of Incorporation of the Surviving Corporation; (c)
the Bylaws of Prospect Medical Systems shall be the Bylaws of the Surviving
Corporation; (d) the directors of the Surviving Corporation shall be as set
forth in Section 2.5 hereof; (e) the officers of the Surviving Corporation shall
be as set forth in Section 2.5 hereof; and (f) the Merger shall, from and after
the Effective Time, have all the effects provided by applicable law.

     2.3  EFFECT ON CAPITAL STOCK.  As of the Effective Time, by virtue of the
Merger and without any action on the part of the holder of any shares of the
issued and outstanding shares of Prospect Medical Systems Common:

          (a)  CAPITAL STOCK OF MS ACQUISITION CORPORATION.  All issued and
outstanding shares of capital stock of MS Acquisition Corporation shall continue
to be issued and shall be converted into 1,000 shares of Common Stock of the
Surviving Corporation.  Each stock certificate


                                         -3-
<PAGE>

of MS Acquisition Corporation evidencing ownership of any such shares shall
continue to evidence ownership of such shares of capital stock of the Surviving
Corporation.

          (b)  CONVERSION OF PROSPECT MEDICAL SYSTEMS COMMON.  Other than
fractional shares as provided in Section 2.3(e), each share of Prospect Medical
Systems Common issued and outstanding immediately prior to the Effective Time
shall be converted, without any action on the part of the holders thereof, into
approximately 55,056 shares of Med-Search Common (hereinafter the "Stock
Exchange Ratio") such that shareholders of Prospect Medical Systems collectively
will own 88,089,312 shares of the Med-Search Common (which is intended to
represent approximately 42% of Med-Search Common immediately after the Effective
Time, including shares issued in the Med-Search Placement (defined in Section
7.1(g) herein).

          (c)  ADJUSTMENT OF EXCHANGE RATIO.  If between the date of this
Agreement and the Effective Time, the outstanding shares of Med-Search Common or
Prospect Medical Systems Common shall have been changed or are proposed to be
changed into a different number of shares or a different class by reason of any
reclassification, recapitalization, split-up, combination, exchange of shares or
readjustment due to due diligence or other investigation (including but not
limited to the Franklin lawsuit, described more fully in Exhibit D hereto), the
Stock Exchange Ratio shall be correspondingly adjusted, so that the existing
Med-Search Stockholders, Prospect Medical Systems Stockholders and Investor will
hold approximately 16%, 42% and 42%, respectively, of the outstanding Med-Search
Common, at the Closing Date, including shares issued in the Med-Search
Placement.

          (d)  DISSENTERS' RIGHTS OF STOCKHOLDERS.  Any Dissenting Shares shall
receive such consideration as may be determined pursuant to Section 1300 of the
California General Corporation Law.  Each of Med-Search and Prospect Medical
Systems agrees that except with the prior written consent of the Investor, or as
required under the California General Corporation Law, it will not voluntarily
make any payment with respect to, or settle or offer to settle, any such demand
for appraisal.  Each Dissenting Stockholder who becomes entitled to payment of
the value of shares shall receive payment therefor (but only after the value
therefor shall have been agreed upon or finally determined pursuant to such
provisions). 

          (e)  FRACTIONAL SHARES.  No fractional shares of Med-Search Common
shall be issued, but in lieu thereof each holder of shares of Prospect Medical
Systems Common who would otherwise be entitled to receive a fraction of a share
of Med-Search Common (after aggregating all fractional shares of Med-Search
Common to be received by such holder) shall receive from Med-Search an amount of
cash (rounded up to the nearest whole cent) equal to the product of (i) the
fraction of a share to which such holder would otherwise be entitled, multiplied
by (ii) the average closing bid price of a share of Med-Search Common for the
ten (10) most recent days on which Med-Search Common has traded on the OTC
Bulletin Board ending the trading day immediately prior to the Closing Date.

     2.4  EXCHANGE OF CERTIFICATES.

          (a)  EXCHANGE AGENT.  Prior to the Effective Time, Med-Search shall
appoint  American Stock Transfer & Trust to act as exchange agent (the "Exchange
Agent") in the Merger.



                                         -4-
<PAGE>

          (b)  MED-SEARCH TO PROVIDE COMMON STOCK.  Promptly after the Effective
Time, Med-Search shall make available to the Exchange Agent for exchange in
accordance with this Article 2 and the Certificate of Merger, through such
reasonable procedures as Med-Search may adopt, the shares of Med-Search Common
issuable pursuant to Section 2.3 in exchange for outstanding shares of Prospect
Medical Systems Common.

          (c)  EXCHANGE PROCEDURES.  As soon as practicable after the Effective
Time, the Exchange Agent shall mail to each holder of record of a certificate or
certificates which immediately prior to the Effective Time represented
outstanding shares of Prospect Medical Systems Common (the "Certificates") whose
shares are being converted into Med-Search Common pursuant to Section 2.3,
instructions for use in effecting the surrender of the Certificates in exchange
for Med-Search Common.  Upon surrender of a Certificate for cancellation to the
Exchange Agent, the holder of such Certificate shall be entitled to receive in
exchange therefor the number of shares of Med-Search Common and payments in lieu
of fractional shares to which the holder of Prospect Medical Systems Common is
entitled pursuant to Section 2.3 and the Certificate of Merger and is
represented by the Certificate so surrendered.  The Certificate so surrendered
shall forthwith be canceled.  In the event of a transfer of ownership of
Prospect Medical Systems Common which is not registered in the transfer records
of Prospect Medical Systems, the appropriate number of shares of Med-Search
Common may be delivered to a transferee if the Certificate representing the
right to receive such Med-Search Common is presented to the Exchange Agent and
accompanied by all documents required to evidence and effect such transfer and
to evidence that any applicable stock transfer taxes have been paid.  Until
surrendered as contemplated by this Section 2.4, each Certificate shall be
deemed at any time after the Effective Time to represent the right to receive
upon such surrender the number of shares of Med-Search Common as provided by
this Section 2.4 and the Delaware General Corporation Law.  The Exchange Agent
shall follow the same procedure with respect to lost, stolen or mutilated
Prospect Medical Systems certificates as it follows with respect to lost, stolen
or mutilated Med-Search certificates.  Unless and until any such certificates
shall be so surrendered, any dividends paid or other distributions made to
holders of record of Med-Search Common after the Effective Time shall be paid to
and retained by the Exchange Agent and paid over to such holder when such
certificate is surrendered in accordance with this Section 2.4(c).

     2.5  BOARD OF DIRECTORS, OFFICERS.  Upon the Effective Time:

          (a)  The directors of the Surviving Corporation shall be as named in
the Certificate of Merger and each shall remain a director from the Effective
Time until such director's successor shall have been elected and shall qualify,
or as otherwise provided in the By-laws of the Surviving Corporation.

          (b)  The officers of the Surviving Corporation shall be as named in
the Certificate of Merger and shall each hold office from the Effective Time
until such officer's successor shall have been elected and shall qualify, or as
otherwise provided in the By-laws of the Surviving Corporation.

          (c)  If at the Effective Time a vacancy shall exist in the Board of
Directors or in any of the offices of the Surviving Corporation, such vacancy
may thereafter be filled in the manner provided in the Bylaws of the Surviving
Corporation.


                                         -5-
<PAGE>

     2.6  NO FURTHER OWNERSHIP RIGHTS IN PROSPECT MEDICAL SYSTEMS COMMON.  All
Prospect Medical Systems Common delivered upon the surrender for exchange of
shares of Med-Search Common in accordance with the terms hereof shall be deemed
to have been delivered in full satisfaction of all rights pertaining to such
shares of Prospect Medical Systems Common.  There shall be no further
registration of transfers on the stock transfer books of the Surviving
Corporation of the shares of Prospect Medical Systems Common which were
outstanding immediately prior to the Effective Time.  If, after the Effective
Time, Certificates are presented to the Surviving Corporation for any reason,
they shall be canceled and exchanged as provided in this Article 2.

     2.7  TAX TREATMENT.  The parties intend that the Merger will be a
non-taxable transaction to the holders of Prospect Medical Systems Common under
section 368 of the Internal Revenue Code of 1986, as amended (the "Code").

     2.8  SECTION 203 OF THE DGCL NOT APPLICABLE.  The provisions of Section 203
of the Delaware General Corporation Law will not, prior to the termination of
this Agreement, apply to this Agreement, the Merger or the transactions
contemplated hereby and thereby.


                                      ARTICLE 3

                         REPRESENTATIONS AND WARRANTIES OF
                PROSPECT MEDICAL SYSTEMS AND PROSPECT MEDICAL GROUP

     Each of Prospect Medical Systems and Prospect Medical Group, individually,
hereby represent and warrant to Med-Search and Investor as follows; provided

Group is a corporation duly organized, validly existing and in good standing
under the laws of its state of incorporation and in each of the other
jurisdictions in which it owns or leases property or conducts business, except

authority to own, lease and operate its properties and to carry on its business,

Certificate of Merger will be duly executed and delivered by Prospect Medical
Systems and will constitute a valid and binding obligation of Prospect Medical

Provided the conditions in Article 7 are satisfied, the execution and delivery

material benefit under (a) any provision of the charter documents or Bylaws of
Prospect Medical Systems or Prospect Medical Group or (b) any agreement or
instrument, permit, franchise, license, judgment or order, applicable to

or Prospect Medical Group.  Prospect Medical Systems and Prospect Medical Group
have prepared and delivered to Med-Search a full and complete list of all
necessary regulatory consents, waivers and approvals (together with any other
material consents, waivers or approvals from third parties, the "Consents") of

     12.10     DISPUTE.  The parties acknowledge that the transactions
contemplated by this Agreement are of a special, unique and extraordinary
character, which gives this Agreement a peculiar value, the loss of which cannot
be reasonably or adequately compensated in damages in an action at law, and a
breach by any party of the provisions of this Agreement will cause irreparable
injury.  It is, therefore, expressly acknowledged that this Agreement may be
enforced by the parties and by Investor by injunction and other equitable
remedies, without bond.  Such relief shall not be exclusive, but shall be in
addition to any other available rights or remedies.  If injunctive relief is not
sought, any controversy or claim arising out of or relating to this Agreement,
or breach thereof, including without limitation claims against either party, its
affiliates, employees, professionals, officers or directors shall be settled by
binding arbitration in Los Angeles, California, in accordance with the
Commercial Rules of the American Arbitration Association.  The arbitrator shall
be an active member of the California bar.  In the proceeding, the arbitrator
shall apply California substantive law and the California Evidence Code, except
that the arbitrator's authority in awarding damages shall be interpreted under
New York law.  THE PARTIES AGREE THAT THE ARBITRATOR SHALL HAVE NO AUTHORITY TO
AWARD PUNITIVE DAMAGES, AND THE PARTIES HAVE BEEN ADVISED TO SEEK COUNSEL
CONCERNING THE POSSIBLE WAIVER BY THE PARTIES OF CERTAIN RIGHTS OTHERWISE
AVAILABLE AS A CONSEQUENCE OF SUCH AGREEMENT.  The arbitrator shall prepare an
award in writing, which shall include factual findings and any legal conclusions
on which the decision is based.  Judgment upon any award rendered by the
Arbitrator(s) may be entered in any court having jurisdiction thereof.  In any
such proceeding, the prevailing party shall be entitled, in addition to any
other relief awarded or adjudged, such sum as the Arbitrator(s) may fix as and
for reasonable attorneys' fees and costs, and the same shall be included in the
award and any judgment.

     12.11     SEVERABILITY.  If for any reason whatsoever, any one or more of
the provisions of this Agreement shall be held or deemed to be inoperative,
unenforceable or invalid as applied to any particular case or in all cases, such
circumstances shall not have the effect of rendering such provision invalid in
any other case or of rendering any of the other provisions of this Agreement
inoperative, unenforceable or invalid.

     12.12     THIRD PARTY BENEFICIARIES.  Except as expressly set forth herein,
no provision of this Agreement, including the Exhibits and Schedules hereto, is
intended or should be construed to create any third party beneficiaries or to
give any rights, including rights of subrogation, to any person other than the
parties to this Agreement.  Notwithstanding the foregoing, Med-Search and
Prospect Medical Systems each hereby agree and acknowledge that Investor is
relying on their respective representations in Articles 3 and 4 and that
Investor or his investor group are relying on the same representations for their
investment in the Med-Search Private Placement.

     12.13     BEST EFFORTS; FURTHER ASSURANCES.  Subject to the terms and
conditions of this Agreement, each party shall use its best efforts to take, or
cause to be taken, all action and to do, or cause to be done, all things
necessary, proper or advisable consistent with applicable laws and regulations
to consummate the transactions contemplated by this Agreement as promptly as
possible.  The parties hereto shall do and perform or cause to be done and

                     AGREEMENT FOR THE PURCHASE AND SALE OF STOCK


     THIS AGREEMENT FOR THE PURCHASE AND SALE OF STOCK ("Stock Purchase
Agreement") is made and entered into as of the 23 day of  June, 1997, by and
among Prospect Medical Group, Inc., a California professional corporation
("Purchaser"), as buyer, Melvin L. Reich, D.O. ("Seller") as seller, and Santa
Ana/Tustin Physicians Group, Inc. a California professional corporation
("Company").


                                   R E C I T A L S

     This Stock Purchase Agreement is made with reference to the following facts
and circumstances:

     A.     Seller owns all of the capital stock of the Company, which owns and
operates a medical practice and an independent practice association located at
999 North Tustin Avenue, Suite 120, Santa Ana, California (the "Practice");

     B.     The Practice provides professional medical services in Orange
County, California, primarily through a capitated contract with PacifiCare, a
health maintenance organization;

     C.     Seller desires to sell to Purchaser and Purchaser desires to
purchase from Seller all of the issued and outstanding stock (the "Stock") of
the Company on the terms and conditions set forth in this Stock Purchase
Agreement.

            NOW, THEREFORE, in consideration of the covenants and conditions
contained herein and for other valuable consideration, the receipt and
sufficiency of which are hereby acknowledged, the parties hereby agree as
follows:

1.   PURCHASE AND SALE OF STOCK:

     On the "Closing Date" (as defined in Section 8.1 herein), Seller shall sell
and assign to Purchaser, and Purchaser shall acquire from Seller, all right,
title and interest in and to the Stock, free and clear of all liens, mortgages,
pledges, claims, security interests, title defects, encumbrances, charges and
other restrictions of every kind (collectively, the "Liens") on the terms and
subject to the conditions set forth in this Stock Purchase Agreement.  Seller is
the owner of record of all of the Company's issued and outstanding capital
Stock.

2.   ASSUMPTION OF LIABILITIES:

     Except for trade payables arising in the ordinary course of business, all
of the liabilities of Company or the Practice as of March 31, 1997, exceeding
$5,000 individually, are set forth on Exhibit 2 attached hereto, which Exhibit 2
shall also include aggregate amounts for each category of liabilities. Seller
shall provide for the payment of such liabilities out of the Reserve Account, as

<PAGE>

defined in Section 3.5 herein, and, to the extent that the Reserve Account is
insufficient to pay such liabilities, Seller shall be individually responsible
for payment of all claims or liabilities of the Company or the Practice which
arose or accrued prior to the Closing.  Purchaser shall assume no liabilities of
Company or the Practice existing as of the Closing Date, and in the event that
Purchaser is unable to satisfy or pay such liabilities from the Reserve Account
or otherwise, Purchaser shall have a right of indemnification against Seller
with respect to any such liabilities or obligations of the Company which
Purchaser is ultimately required to pay.

3.   PURCHASE PRICE OF STOCK:

     3.1    CONSIDERATION.  Subject to the terms and conditions of this Stock
Purchase Agreement, in reliance on the representations, warranties and covenants
of the parties hereto (including the Non-Competition Agreement of Seller
attached hereto as Exhibit 8.2(f) and incorporated herein by this reference),
and in full consideration of the sale, assignment and delivery of the Stock,
Purchaser shall pay to the Seller Five Million Dollars ($5,000,000) on or before
the Closing, as set forth herein, plus all amounts, if any, which remain in the
Reserve Account, as defined in Section 3.5 herein, on the date one year from the
date of this Stock Purchase Agreement in accordance with Section 3.2 below (the
"Purchase Price").  For the purposes of this Stock Purchase Agreement, the
parties agree that no portion of the sale price shall be apportioned to
Company's CalOPTIMA contract or assets related thereto, although Company is
transferring all right, title and interest to such contracts or assets as
permitted by law.  The parties further agree that the restrictions contained in
the Non-Competition Agreement by and between Purchaser and Seller, the form of
which is attached hereto as Exhibit 8.2(f), are incidental to the goodwill being
acquired by Purchaser hereunder and that no separate compensation or
consideration is being paid with respect to the provisions contained in the
Non-Competition Agreement.

     3.2    PAYMENT OF THE PURCHASE PRICE.

            (a)    Purchaser shall pay Seller in the aggregate, Five Million
Dollars ($5,000,000) in cash, plus all amounts, if any, which remain in the
Reserve Account on the date one year from the date of this Stock Purchase
Agreement.  Payment shall be made as follows:  At the date of the parties'
execution of this Stock Purchase Agreement, Purchaser shall (i) pay One Hundred
Thousand Dollars ($100,000) to Seller, and (ii) deposit One Million Nine Hundred
Thousand Dollars ($1,900,000) into an escrow account established by Purchaser
with Seller's consent, established pursuant to instructions given in the form of
those set forth on Exhibit 3.2(a) ("Escrow Account").  At the conclusion of
twenty-one (21) days from the date hereof, Nine Hundred Thousand Dollars
($900,000) from the Escrow Account shall be paid to Seller.  Unless such funds
have already been disbursed to Seller, at the Closing Date Purchaser shall pay
Three Million Dollars ($3,000,000) to Seller and direct the payment of the
remaining One Million Dollars ($1,000,000) in the Escrow Account to Seller.  On
the date that is forty-two (42) days from the date of this Stock Purchase
Agreement, the One Million Dollars ($1,000,000) remaining in the Escrow Account
shall be paid to Seller, and the remaining Three Million Dollars ($3,000,000)
owed shall be paid on the Closing Date.  It shall be a condition to the
effectiveness of the Stock Purchase Agreement that the $1.9 million to be paid
into the Escrow Account have been wired into the Escrow Account.


                                          2

            (b)    Except for the payment of the $100,000 deposit, which shall
be paid through a journal entry transfer from Purchaser's Merrill Lynch account
to Seller's Merrill Lynch account, and which shall be confirmed by facsimile and
telephone, all such sums payable hereunder shall be payable to Seller by way of
wire transfer of immediately available funds into a deposit account designated
in writing by Seller.  Purchaser and Seller agree that the $100,000 payment made
as of the date of this Stock Purchase Agreement shall be non-refundable.  The
parties further agree that in the event that the transactions contemplated
herein have not been consummated on or before forty-two (42) days from the date
hereof, all remaining funds in the Escrow Account shall be paid to Seller unless
(i) Seller commits fraud related to this Stock Purchase Agreement or the
operation of the Company or the Practice, or (ii) there is a material breach of
the representations, warranties and covenants set forth in Sections 4.1, 4.2,
4.3, 4.4 (solely with respect to agreements with health maintenance
organizations, provider agreements and the leases of Company's facilities, and
in such cases only where the material breach is so severe as to interfere with
Company's business), 4.6, 4.7(a), 4.7(e), 4.12(b), 4.12(c), 4.14 (only to the
extent such undisclosed lawsuit is not covered by insurance), 4.15 (only to the
extent Seller has violated a criminal statute), 4.17, 4.18(b) and 4.32 of this
Stock Purchase Agreement by Company or Seller; provided however, that in the
event of the aforementioned material breaches of the representations, warranties
and covenants of this Stock Purchase Agreement set forth in item (ii), Seller
shall have 20 days from the date of notice of such material breach to cure such
breach ("Cure Period").  During the Cure Period the Purchaser's obligations to
pay any amounts from the Escrow Account shall be suspended.

            (c)    Prior to the Closing, in the event that any or all of the
amounts in the Escrow Account have been disbursed to Seller and Purchaser
becomes aware of a material breach of this Agreement as set forth in items (i)
or (ii) above, Seller shall immediately return such amounts (except for the
nonrefundable $100,000 deposit) to Purchaser, subject to Seller's Cure Period.

     3.3    OTHER CONSIDERATION.  As additional consideration for the execution
of this Stock Purchase Agreement and the transactions contemplated hereby, the
parties agree that Seller and Company shall assign to Purchaser the option to
purchase Premier IPA and will assign, if executed, an option to purchase Western
IPA.

     3.4    FAIR MARKET VALUE.  The parties agree that the Purchase Price
reflects the fair market value of the Stock as valued by a third party,
independent appraiser in accordance with accepted business practices for valuing
the stock of professional medical practices.  The parties agree no consideration
is or will be paid for the value of any referrals (direct or indirect) to or
from Purchaser, Seller, or any of his affiliates.

     3.5    RESERVE ACCOUNT.  Concurrent with the Closing (as hereinafter
defined in Section 8.1), the Company shall establish a reserve account (the
"Reserve Account").  The Reserve Account will be used to offset liabilities of
the Company existing as of the Closing Date.  The Reserve Account shall
initially consist of the liquid assets of the Company as of the Closing,
including, but not limited to, the Company's cash, money market accounts,
reserves, securities, checking accounts and Merrill Lynch account.  All money
earned or accrued for the period prior to the Closing but received by the
Company after the Closing, including, but not limited to, such items as receipt
of hospital control funds, stop loss payments, maternity guarantee, mammogram


                                          3
<PAGE>

pools, retroactive capitation payments, and the Company's accounts receivable
existing as of the Closing shall be deposited in the Reserve Account.
Additionally, any prepaid liabilities of the Company for the period relating to
after the Closing shall be credited to the amount of the Reserve Account.  Any
refunds given to the Company after the Closing which relate to the period prior
to the Closing shall also be deposited into the Reserve Account.  Purchaser
shall notify Seller of any such required deposits within five (5) days of
receipt of such funds by Company or Purchaser.  The Reserve Account shall be a
separate mutually agreed upon account for which the signatures of both Seller
and Purchaser shall be required, although Seller shall oversee all payments made
from the Reserve Account.  Seller shall provide Purchaser with copies of all
checks issued relating to the Reserve Account together with copies of the
supporting bills which are being paid.  Except for liabilities related to the
transfer of capitated lives from Seoul Medical Group, Inc. prior to
December 1, 1996 (the "Seoul Liabilities"), any pre-Closing liabilities of the
Company shall be paid by Seller from the Reserve Account, including, but not
limited to, pre-Closing tax liabilities and the premiums for Seller's "tail"
malpractice insurance policy relating to the period prior to the Closing.
Except for the Seoul Liabilities, the pre-Closing liabilities will include any
liability of the Company which has a date of service (regardless of when billed)
prior to the Closing.  The funds in the Reserve Account shall not be removed
from the Reserve Account for any purpose other than (i) for the payment of the
pre-Closing liabilities of the Company; (ii) for possible indemnification
purposes pursuant to Section 9 of this Agreement; or (iii) for distribution to
Seller upon liquidation of the Reserve Account.  Prior to Seller incurring any
liability for any indemnification pursuant to Section 9 of this Agreement, it
shall be a precondition first that funds in the Reserve Account shall first be
required to be used and applied until all such funds in the Reserve Account have
been exhausted.  There shall be no requirement for the Company to deposit any
funds into the Reserve Account other than as required pursuant to this Section
3.5.  At any time after the Closing up through the date when the Reserve Account
is liquidated, in the event that the amount of the pre-Closing claims and
pre-Closing liabilities of the Company exceed the amount which is held in the
Reserve Account, Seller shall pay to Purchaser within thirty (30) days the
amount by which such claims and liabilities exceed the amount held in the
Reserve Account.  On the first anniversary of the Closing Date, in the event
that the pre-Closing liabilities of the Company and the pre-Closing claims
against the Company are less in the aggregate than the amount held in the
Reserve Account, such surplus shall be distributed from the Reserve Account to
Seller.  The Reserve Account will have a balance of at least Five Hundred
Thousand Dollars ($500,000) cash or other liquid securities at the Closing.

     3.6    EXPENSES.  Seller shall be individually responsible for all federal,
state and local taxes, transfer tax and documentary stamps, if any, through and
including the date of Closing attributable to or arising out of the sale of the
Stock to Purchaser or with respect to the Company, and the arrangements in
connection with the Closing of such sale.

credit for their prior service on behalf of Company, including, but not limited

with Purchaser's current policies.  With respect to severance benefits,
Purchaser agrees that if any Company employee listed in Section 8.5(e) of this
Stock Purchase Agreement is terminated without cause prior to the end of such
person's employment agreement, such employee shall receive severance pay equal
to (i) the remaining term of his or her employment agreement, plus (ii) one

entitled to receive bonuses for services rendered prior to Closing at the
discretion of Seller from Hospital Bonus Funds to be paid into the Reserve

Prospect Medical Systems does not enter into an employment agreement with
Ingels, Purchaser agrees to provide Ingels with health and vacation benefits and
the severance benefits set forth in this Section 6.1, as if Ingels were employed
under the form of employment agreement set forth in Schedule 8.2(h) for one
year.  In the event of a termination of Ingels without cause, any such severance
payments paid by Purchaser or Company will offset the remaining amount owed by
Seller to Ingels under Ingel's current employment agreement with Company.

(18) month period following the Closing, Purchaser will maintain Company's

any of their affiliates (collectively, "St. Joseph's").  Purchaser further
agrees that for a period of six (6) months following the Closing Date, Purchaser
will not sell, offer or otherwise dispose of the shares or assets of Company to
any other purchaser.  In the event that Purchaser sells Company after such six
month period, Purchaser agrees that such sale will contain negative covenants
prohibiting the subsequent purchaser of Company from selling Company to St.
Joseph's for a twenty-four (24) month period following the Closing Date of this
transaction.  Notwithstanding the foregoing, Seller and Company acknowledge that
nothing herein shall be construed to prevent or otherwise limit the sale of all
or a part of Purchaser to another entity.

9.   INDEMNIFICATION:

     9.1    SELLER'S INDEMNITY.

            (a)    Except as provided in subsection (b) herein, for a period of
three (3) years from the Closing Date, Seller shall indemnify, defend and hold
Purchaser, its affiliates (including without limitation, Company), and their
directors, officers, employees, attorneys, and agents harmless from and against
any and all liabilities, losses, damages, claims, causes of action, costs and
expenses (collectively "Claims") (including, without limitation, reasonable
attorneys' fees and expenses and court costs), whether known or unknown, whether
suit is instituted or not, and, if instituted, whether at any trial and
appellate level, for the period prior to the Closing, arising out of, relating
to or as a result of:  (a) Company's and/or Seller's ownership or operation of
Company or the Practice, including any defects in title; (b) any other actions
or omissions of Company prior to the Closing Date; (c) any default or breach by
Company or Seller of any representation, warranty or any other material term or
condition in this Stock Purchase Agreement (including the exhibits and
attachments) or any ancillary agreement, document, or certificate to be
delivered in connection with this Stock Purchase Agreement; (d) the conduct of
Company's business on or prior to the date of the Closing, including, without
limitation, any litigation now existing or hereafter arising from such conduct
occurring on or prior to the Closing Date, (e) any inaccuracy of the Company
Financial Statements; and (f) any act, conduct, omission or commitment of
Company or Seller occurring on or prior to the Closing Date, which may hereafter
be asserted against Company or Seller, whether or not unknown, unasserted or
undiscovered by Purchaser as of Closing, but only to the extent not actually
reimbursed to Purchaser by insurance and only in an amount up to $1,000,000,
exclusive of any amounts in the Reserve Account.  Purchaser agrees that with
respect to any matter for which Seller has the foregoing obligations, Purchaser
shall first attempt to satisfy the amount owed by Seller out of the Reserve
Account.  Without limiting the generality of the foregoing, with respect to the
measurement of damages, the Purchaser shall have the right to be put in the same
financial position as it would have been in had the representations and
warranties of Seller been true and correct, had each of the covenants of Company
and Seller been performed in full, and had Company and Seller paid, discharged
and performed all of the liabilities and obligations of the Seller.

            (b)    Notwithstanding the foregoing, the three year duration of
Seller's indemnification and the limit of $1,000,000 in amount set forth in
subsection (a) above shall not apply to Claims related to (i) fraud, (ii) tax
liabilities, (iii) a violation of state or federal statutes or regulations
governing the practice of medicine, or (iv) Claims of which Seller was aware as
of the Closing Date that were not disclosed to Purchaser, which Claims shall
survive indefinitely.


                                          24
<PAGE>

     9.2    PURCHASER'S INDEMNITY.  Purchaser shall indemnify, defend and hold
Seller harmless from and against any and all Claims (including, without
limitation, reasonable attorneys' fees), arising out of (a) Purchaser's
ownership or operation of Company or the Practice following the Closing Date,
(b) any other actions or omissions of Company following the Closing Date; (c)
any default or breach by Purchaser of any representation, warranty or any other
material term or condition in this Stock Purchase Agreement (including the
exhibits and attachments) or any ancillary agreement, document, or certificate
to be delivered in connection with this Stock Purchase Agreement; (d) the
conduct of Company's business following the date of the Closing; and (e) any
act, conduct, omission or commitment of Company occurring following the Closing
Date.  Notwithstanding the foregoing, Purchaser's indemnification of Seller
shall be limited to a period of three (3) years from the Closing Date and an
amount up to $1,000,000, except for Claims related to (i) fraud, (ii) tax
liabilities, or (iii) a violation of state or federal statutes or regulations
governing the practice of medicine, which claims shall survive indefinitely.

     9.3    INDEMNIFICATION PROCEDURE.

     (a)    In the event any person or entity not a party to this Stock Purchase
Agreement shall make a demand or Claim or file or threaten to file or continue
any lawsuit, which demand, Claim or lawsuit may result in liability to an
indemnified party under this Stock Purchase Agreement, or in the event that a
potential loss, damage or expense comes to the attention of any party, then the
party receiving notice or aware of such event shall promptly notify the other
party or parties of the demand, Claim or lawsuit.  Within ten (10) days after
notice by the indemnified party (the "Notice") to an indemnifying party of such
demand, Claim or lawsuit, except as provided in subsection (b) herein, the
indemnifying party shall have the option, at its cost and expense, to retain
counsel for the indemnified party, to defend any such demand, claim or lawsuit,
provided that counsel who will conduct the defense of such claim or litigation
will be approved by the indemnified party whose approval will not unreasonably
be withheld.  The indemnified party shall have the right, at its own expense, to
participate in the defense of any suit, action or proceeding brought against it
with respect to which indemnification may be sought hereunder, provided, (a) if
the named parties to any such proceeding (including any impleaded parties)
include both the indemnifying party and the indemnified party and representation
of both parties by the same counsel would be inappropriate due to actual or
potential differing interests between them, (b) the employment of counsel by
such indemnified party has been authorized in writing by the indemnifying party,
or (c) the indemnifying party has not in fact employed counsel to assume the
defense of such action within a reasonable time; then, the indemnified party
shall have the right to retain its own counsel at the cost and expense of the
indemnifying party.  No indemnifying party, in the defense of any such claim or
litigation, will consent to entry of any judgment or enter into any settlement
without the consent of the indemnified party.  If any indemnified party will
have been advised by counsel chosen by it that there may be one or more legal
defenses available to such indemnified party which are different from or
additional to those available to and which have not been asserted by the
indemnifying party, the indemnifying party will not have, at the election of the
indemnified party, the right to continue the defense of such claim or action on
behalf of such indemnified party and will reimburse such indemnified party and
any person controlling such indemnified party for the reasonable fees and
expenses of any counsel retained by the indemnified party to undertake the
defense. In the event that the indemnifying party shall fail to respond within
ten (10) days after receipt of the Notice, the indemnified party may retain
counsel and


                                          25
<PAGE>

conduct the defense of such demand, claim or lawsuit, as it may in its sole
discretion deem proper, at the sole cost and expense of the indemnifying party.
Except as explicitly provided in this Section 9.3, failure to provide Notice
shall not limit the rights of such party to indemnification.

     (b)    Notwithstanding the foregoing, in the event that any demand, Claim
or lawsuit for which indemnification is payable hereunder relates with respect
to Seller or Company, to a criminal investigation, quasi criminal investigation,
governmental regulatory claim, civil claim involving allegations of criminal
conduct, or a matter in which the licensure of Purchaser or Company could be
jeopardized, Purchaser shall have the sole right to retain counsel to represent
it or the Company in such matter and Seller shall pay the reasonable fees of
such counsel on a current basis; provided however, that Purchaser shall
collaborate in good faith with Seller and his counsel in the handling of such
matters.  In the event Purchaser determines to settle any such matter, it shall
provide Seller and his counsel with 30 days prior notice of Purchaser's
intention to settle, specifying the amount payable and other material terms of
the proposed settlement.  Within 10 days of such notice, Seller shall notify
Purchaser of its intention to pay such proposed settlement.  If Seller elects
not to pay the settlement amount, Purchaser may at its sole discretion elect
either to (i) provide for the payment of such settlement and may seek
reimbursement from Seller for the amount of such settlement and all fees and
costs associated therewith, by submitting a claim in arbitration to determine
whether Purchaser's actions were reasonable actions for a prudent person under
the circumstances under which they were made, or (ii) tender the continuing
defense of such action to Seller and its counsel as provided herein.

     9.4    PAYMENT; PURCHASER'S RIGHT TO OFFSET.  All amounts paid by either
party pursuant to this Section 9 shall be on a dollar-for-dollar basis as to the
claims for which indemnification is to be paid.  All amounts shall be on an
after-tax basis, with such tax effects to be determined within 20 days of the
completion of an audit of Company's financial statements for the first fiscal
period following the Closing Date.  With regard to claims of third parties for
which indemnification is payable hereunder, such indemnification shall be paid
by the indemnifying party in advance of settlement or final adjudication thereof
on a current basis within thirty (30) days of receipt from the indemnified party
of such supporting documentation as the indemnifying party may reasonably
request, and any offset of such amounts due to the determination of the tax
effects as set forth herein shall be paid within 30 days of the completion of
such audit of Company's financial statements for the first fiscal period
following the Closing Date.  Anything herein to the contrary notwithstanding,
Purchaser shall be required to offset any amounts due to Purchaser from Seller
under this Section 9 by first offsetting the amount of the Reserve Account,
after which Purchaser may seek indemnification directly from the Seller.
Purchaser shall not be permitted to offset any amounts owed hereunder against
sums owed to Seller under the Employment Agreement.

     9.5    NON-EXCLUSIVE REMEDY/MITIGATION OF DAMAGES.  The provisions of this
Section 9 do not limit the parties' right to choose any and all available
remedies for breach, provided, however, that the parties shall first look to
indemnification to the extent such monetary remedy shall be appropriate.
Notwithstanding the foregoing, before seeking indemnification from Seller,
Purchaser shall be required to mitigate all amounts owed by Seller hereunder.
Such duty to mitigate shall include, but not be limited to, Purchaser's
obligation to satisfy amounts owed out of the Reserve Account.


                                          26
<PAGE>

10.  PURCHASER'S CANCELLATION OF STOCK PURCHASE AGREEMENT:

     10.1   JEOPARDY.  In the event the performance by Seller of any term,
covenant, condition or provision of this Agreement should be in violation of any
statute, ordinance, or be otherwise deemed illegal, by a state or federal court
or governmental agency  (collectively, "Jeopardy Event"), then the parties shall
use their best efforts to meet forthwith and attempt to negotiate an amendment
to this Stock Purchase Agreement to remove or negate the effect of the Jeopardy
Event.  In the event the parties are unable to negotiate such an amendment
within twenty (20) days following written notice by either party of the Jeopardy
Event, then Purchaser may cancel this Agreement immediately upon written notice
("Cancellation Option"), and except for the $100,000 deposit, all amounts
previously paid by Purchaser to Seller shall be paid within ten (10) days.

     10.2   EXERCISE OF CANCELLATION OPTIONS.  In the event Purchaser exercises
the Cancellation Option described above, it shall so notify Company in writing
and each party shall return forthwith all originals and copies of any financial
or other records, instruments, or other documents it has received from the other
party and, except as provided in this Agreement, all of the parties' respective
rights and obligations hereunder shall terminate immediately.  Notwithstanding
the foregoing, the parties' respective obligations under Section 7.2 above shall
survive Purchaser's exercise of any of said cancellation options.

11.  MUTUAL RELEASE

     Except as provided in Sections 3.5 and 9 of this Stock Purchase Agreement,

     (a)    Effective upon the Closing, Seller hereby irrevocably waives,
releases and discharges the Company from any and all liabilities and obligations
of Company to Seller of any kind, or nature whatsoever, whether in his capacity
as the Seller hereunder, as a stockholder, officer, or director of the Company
or otherwise, including, without limitation, in respect of rights of
contribution or indemnification, in each case whether absolute or contingent,
liquidated or unliquidated, and whether arising at law or equity, and Seller
hereby covenants and agrees that he will not seek to recover any amounts in
connection therewith or thereunder from the Company; provided, however, that
nothing in this Section 11 will constitute a waiver of any claims Seller may
have against the Company pursuant to the terms of this Agreement, including but
not limited to a material breach of any representation or warranty contained
herein, and/or any acts or events which occur after the Closing.

     (b)    Effective upon the Closing, Company hereby irrevocably waives,
releases and discharges Seller from any and all liabilities and obligations of
Seller to the Company of any kind or nature whatsoever, including, without
limitation, in respect of rights of contribution or indemnification, in each
case whether absolute or contingent, liquidated or unqualified, and whether
arising at law or equity, and the Company hereby covenants and agrees that it
will not seek to recover any amounts in connection therewith or thereunder from
Seller; provided, however, that nothing in this Section 11 will constitute a
waiver of any claims that the Company may have against Seller pursuant to the
terms of this Agreement, including but not limited to a material breach of any
representation or warranty contained herein.


                                          27

     It is the intention of the parties hereto that the foregoing releases shall

     12.1   RISK OF LOSS. Until the Closing, Seller shall bear all risk of loss,
damage or destruction to the assets.

     12.2   NO THIRD PARTY BENEFICIARIES.  The parties intend that the benefits
of this Stock Purchase Agreement shall inure only to Purchaser and the Seller
except as expressly so stated herein.  Notwithstanding anything contained
herein, or any conduct or course of conduct by any party hereto, before or after
signing this Stock Purchase Agreement, this Stock Purchase Agreement shall not
be construed as creating any right, claim or cause of action against Purchaser,
Company or Seller by any other person or entity.

     12.3   ENTIRE AGREEMENT.  This Stock Purchase Agreement, together with all
exhibits and schedules hereto, and all documents referred to herein (including
without limitation any ancillary agreements), constitutes the entire agreement
between the parties with respect to the subject matter hereof, supersedes all

the subject matter hereof.  Each party to this Stock Purchase Agreement
acknowledges that no representations, inducements, promises, or agreements,
orally or otherwise, have been made by the other party(ies), or by anyone acting
on behalf of any party, that are not embodied herein, and that no other
agreement, statement, or promise not contained in this Stock Purchase Agreement

     12.4   SUCCESSORS AND ASSIGNS.  This Stock Purchase Agreement shall be

interests or obligations hereunder; provided, however, that Purchaser may, (i)
assign any or all of its rights and interests hereunder to one or more of its
Affiliates, except for the actual purchase of Seller's stock in Company, and
(ii) designate one or more of its Affiliates to perform its obligations
hereunder (in any or all of which cases Purchaser shall remain liable and
responsible for the performance of all of its obligations hereunder).  Any
assignment or delegation in contravention of this Section shall be null and
void.

original document, but which together shall constitute one and the same
instrument.

injunctive relief to prevent such a breach and specifically to enforce the terms
and provisions hereof in any action instituted in a court of competent
jurisdiction.

Stock Purchase Agreement and each and every provision hereof of which time of
performance is a factor.

     12.16  WAIVERS.  No waiver by any party, whether express or implied, of its
rights under any provision of this Agreement shall constitute a waiver of the
party's rights under such provisions at any other time or a waiver of the
party's rights under any other provision of this Stock Purchase Agreement.  No
failure by any party to take any action against any breach of this Stock
Purchase Agreement or default by another party shall constitute a waiver of the
former party's right to enforce any provision of this Stock Purchase Agreement
or to take action against such breach or default or any subsequent breach or
default by the other party.  To be effective any waiver must be in writing and
signed by the waiving party.

     12.17  ARBITRATION.  The parties firmly desire to resolve all disputes
arising hereunder without resort to litigation in order to protect their
respective business reputations and the confidential nature of certain aspects
of their relationship.  Accordingly, any controversy or claim arising out of or
relating to this Agreement, or the breach thereof, shall be settled by
arbitration as set forth below.

            (a)    All disputes which in any manner arise out of or relate to
this Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 12.17.  Either
party may commence arbitration by sending a written demand for arbitration to
the other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

            (b)    The parties stipulate to arbitration before a single,
mutually agreed upon arbitrator sitting on the Los Angeles, California Judicial
Arbitration Mediation Services (JAMS) panel.  In the event that the parties are
unable to agree upon the person chosen as arbitrator within 30 days of the
demand for arbitration, the arbitrator shall be selected in the sole discretion
of the JAMS administrator.  The arbitrator shall be a member of the California
bar.

            (c)    The parties shall share all costs of arbitration.  The
prevailing party shall be entitled to reimbursement by the other party of such
party's attorneys' fees and costs and any arbitration fees and expenses incurred
in connection with the arbitration hereunder.

            (d)    The substantive law of the State of California shall be
applied by the arbitrator.  All proceedings in arbitration shall be in
accordance with the California Code of Civil Procedure, as amended, and the
parties shall have the right to legal discovery in any matter submitted to
arbitration in satisfaction of California Code of Civil Procedure Section
1283.05, as permitted by California Code of Civil Procedure Section 1283.1(b).

            (e)    Arbitration shall take place in Los Angeles, California
unless the parties otherwise agree.  As soon as reasonably practicable, a
hearing with respect to the dispute or matter to be resolved shall be conducted
by the arbitrator.  As soon as reasonably practicable thereafter, the arbitrator
shall arrive at a final decision, which shall be reduced to writing, signed by
the arbitrator and mailed to each of the parties and their legal counsel.

            (f)    All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement.  The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

            (g)    Notwithstanding the foregoing, because time is of the essence
of this Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar equitable
relief.

            (h)    The decision and award of the arbitrator shall be kept
confidential by the parties to the greatest extent possible.  No disclosure of
such decision or award shall be made by the parties except as required by law or
as necessary or appropriate to effect the enforcement thereof.

            (i)    Should either Employer or Physician institute any action or
procedure to enforce this Agreement or any provision hereof, or for damages by
reason of any alleged breach of this Agreement or of any provision hereof, or
for a declaration of rights hereunder (including without limitation
arbitration), the prevailing party in any such action or proceeding shall be
entitled to receive from the other party all costs and expenses, including
without limitation reasonable attorneys' fees, incurred by the prevailing party
in connection with such action or proceeding.

     12.18  CONSTRUCTION.  The parties have participated jointly in the
negotiation and drafting of this Stock Purchase Agreement and in the event of
any ambiguity or question of intent or interpretation, no presumption or burden
of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any of the provisions of this Stock Purchase Agreement.

     12.19  FURTHER ASSURANCES.  The parties shall take such actions and execute
and deliver such further documentation as may reasonably be required in order to
give effect to the transactions contemplated by this Stock Purchase Agreement
and the intentions of the parties hereto.

(the "Audited Company Financial Statements"); and (ii) an unaudited statement of
operations and accumulated deficit, statement of cash flows for the fiscal

on the Company Balance Sheet or the accompanying notes thereto except for
liabilities incurred in the ordinary course of business since the date of said
balance sheet which are usual and normal in amount and those liabilities which
are set forth in Schedule 3.5.  The reserves reflected in the Audited Company
Financial Statements for IBNR are adequate provisions for such liabilities and
have been established in accordance with GAAP consistently applied.

owing by Company.  No extensions of time or requests therefor or waiver thereof

reports, returns or taxes  ("Taxes").  Company has timely filed or will cause to
be filed on its own behalf and on behalf of the Partnership all tax returns
(federal, state and local) required to be filed on or before the Closing Date,
and all Taxes shown to be due and payable on said returns have been paid.  There
are no actions, suits, proceedings, investigations, audits, claims or liens now
pending against or related to Company or the Partnership regarding any tax or
assessment.  No claim for any additional tax, assessment or reassessment is

Company or Sellers which could result in any claim being asserted with respect
to any such Taxes.  There is no action, dispute, suit, proceeding, investigation

8.   INDEMNIFICATION:

     8.1  SELLER'S INDEMNITY.  Sellers shall indemnify, defend and hold
Purchaser, its affiliates, and their directors, officers, employees, attorneys,
and agents harmless from and against any and all liabilities, losses, damages,
claims, causes of action, costs and expenses (including, without limitation,
reasonable attorneys' fees and expenses and court costs), whether known or
unknown, whether suit is instituted or not, and, if instituted, whether at any
trial and appellate level, exceeding $100,000 in the aggregate, that arise out
of, relate to or result from any default or breach by Company or Sellers of any
representation, warranty, covenant or any other material term or condition in
this Stock Purchase Agreement, including the exhibits and schedules hereto. 
Without limiting the generality of the foregoing, except as provided in Section
8.5 herein, with respect to the measurement of damages, the Purchaser shall have
the right to be put in the same financial position as it would have been in had
the representations, warranties and covenants of Sellers been true and correct,
had each of the covenants of Company and Sellers been performed in full, and had
Company and Sellers paid, discharged and performed all of the liabilities and
obligations of the Sellers.

     8.2  PURCHASER'S INDEMNITY.  Purchaser shall indemnify, defend and hold
Sellers harmless from and against any and all liabilities, losses, damages,
claims, causes of action, costs and expenses (including, without limitation,
reasonable attorneys' fees and expenses and court costs), whether known or
unknown, whether suit is instituted or not, and, if instituted, whether at any
trial and appellate level, exceeding $100,000 in the aggregate, that arise out
of or relate to (a) any default or breach by Purchaser of any representation,
warranty, covenant or any other material term or condition in this Stock
Purchase Agreement, including the exhibits and schedules hereto, or (b) the
conduct of Company's business after the date of the Closing, including, without
limitation, any litigation hereafter arising from such conduct occurring after
the Closing Date.

     8.3  INDEMNIFICATION PROCEDURE.  

          (a)  THIRD PARTY CLAIMS.  

               (i)  In the event any person or entity not a party to this
Agreement shall make a demand or claim or file or threaten to file or continue
any lawsuit, which demand, claim or lawsuit may result in liability to an
indemnified party under this Agreement, or in the event that a potential loss,
damage or expense comes to the attention of any party, then the party receiving
notice or aware of such event shall promptly notify the other party or parties
of the claim.  Within ten (10) days after notice by such third party or by the
indemnified party (the "Notice") to an indemnifying party of such demand, claim
or lawsuit, the indemnifying party must, at its cost and expense, retain counsel
for the indemnified party to defend any such demand, claim or lawsuit, provided
that counsel who will conduct the defense of such claim or litigation will be
approved by the indemnified party 


                                      23
<PAGE>


whose approval will not unreasonably be withheld.  In the event the parties 
cannot agree on such counsel within 30 days of the date of the Notice, the 
indemnified party may select its own counsel and provide for the payment of 
such counsel and its expenses related thereto, during the pendency of such 
demand, claim or lawsuit.  In such cases, at the conclusion of such demand, 
claim or lawsuit, the parties shall select an arbitrator in accordance with 
the provisions set forth in Section 10.18 herein for the sole purpose of 
determining the responsible party for payment of such fees.

               (ii) The indemnified party shall have the right, at its own
expense, to participate in the defense of any suit, action or proceeding brought
against it with respect to which indemnification may be sought hereunder,
provided, that: (a) if the named parties to any such proceeding (including any
impleaded parties) include both the indemnifying party and the indemnified party
and representation of both parties by the same counsel would be inappropriate
due to actual or potential differing interests between them, (b) the employment
of counsel by such indemnified party has been authorized in writing by the
indemnifying party, or (c) the indemnifying party has not in fact employed
counsel to assume the defense of such action within a reasonable time; then, the
indemnified party shall have the right to retain its own counsel at the cost and
expense of the indemnifying party.  No indemnifying party, in the defense of any
such claim or litigation, will consent to entry of any judgment or enter into
any settlement without the consent of the indemnified party.  If any indemnified
party is advised by counsel chosen by it that there may be one or more legal
defenses available to such indemnified party that are different from or
additional to those available to and which have not been asserted by the
indemnifying party, the indemnifying party will not have, at the election of the
indemnified party, the right to continue the defense of such claim or action on
behalf of such indemnified party and will reimburse such indemnified party and
any person controlling such indemnified party for the reasonable fees and
expenses of any counsel retained by the indemnified party to undertake the
defense.  In the event that the indemnifying party shall fail to respond within
ten (10) days after receipt of the Notice, the indemnified party may retain
counsel and conduct the defense of such demand, claim or lawsuit, as it may in
its sole discretion deem proper, at the sole cost and expense of the
indemnifying party.  Except as explicitly provided in this Section 8.3, failure
to provide Notice shall not limit the rights of such party to indemnification.

          (b)  DIRECT BREACH OF AGREEMENT.  In the event any party to this Stock
Purchase Agreement makes a direct demand or claim for indemnification against
the other party hereto for a breach or default of any representation, warranty,
covenant or other material term or conditions of this Stock Purchase Agreement,
the parties shall follow the arbitration procedure set forth in Section 10.18
herein.

     8.4  PAYMENT; PURCHASER'S RIGHT TO OFFSET.  All amounts paid by either
party pursuant to this Section 8.4 shall be on a dollar-for-dollar basis as to
claims for which indemnification is to be paid.  With regard to claims of third
parties for which indemnification is payable hereunder, such indemnification
shall be paid by the indemnifying party in advance of settlement or final
adjudication thereof on a current basis within thirty (30) days of receipt from
the indemnified party of such supporting documentation as the indemnifying party
may reasonably request.  Notwithstanding anything herein to the contrary, in the
event Purchaser seeks indemnification from Sellers related to claims or matters
that have already been adjudicated or settled with the mutual agreement of the
parties hereto, Purchaser shall have the right to offset any amounts due from
Sellers 


                                        24
<PAGE>


under this Section 8.4 by reducing any other amounts due and payable by 
Purchaser to Sellers under the Notes, unless payment is agreed through other 
means.  In the event Purchaser seeks indemnification from Sellers related to 
claims or matters that have not been adjudicated or settled with the mutual 
agreement of the parties hereto and Purchaser desires to reduce any other 
amounts due and payable by Purchaser to Sellers under the Notes, Purchaser 
shall notify Sellers of its intention to settle or pay such claim and offset 
payments under the Notes; provided however, that in such circumstances 
Purchaser shall only reduce payments to be made under the Notes after 
Purchaser has paid an amount equal to the amount proposed to be paid in 
settlement of such third party claim into a mutually agreed upon depository 
account.  The parties shall then follow the arbitration procedures set forth 
in Section 10.18 herein to determine the party responsible for making such 
payment.

     8.5  LIMITATION OF INDEMNITIES.  The aggregate liability of (i) Purchaser,
or (ii) Sellers together, shall not exceed Three Million Dollars
($3,000,000.00), including all costs, expenses and attorneys fees; provided
however, that Sellers' liability shall be joint and several.  Notwithstanding
the foregoing, the Three Million Dollar ($3,000,000) limitation of Sellers'
liability shall not apply to civil or criminal fraud or tax matters, for which
Sellers' liability shall not exceed Three Million Dollars ($3,000,000)
individually, for an aggregate of Six Million Dollars ($6,000,000).  Such
limitation of each party's liability shall include the aggregate amounts paid by
such party as indemnification pursuant to the terms of the Agreement and Plan of
Reorganization by and among Prospect Medical Holdings, Sierra Medical
Management, Inc., Sinnadurai E. Moorthy, M.D., Karunyan Arulanantham, M.D. and
Jayaratnam Jayakumar provided further, that any amounts paid by Prospect Medical
Holdings or any of its affiliates pursuant to such agreement shall count toward
the maximum owed by Purchaser herein.

9.   PURCHASER'S CANCELLATION OF STOCK PURCHASE AGREEMENT:

     9.1  JEOPARDY.  In the event the performance by Sellers of any term,
covenant, condition or provision of this Agreement should be in violation of any
statute, ordinance, or be otherwise deemed illegal, by a state or federal court
or governmental agency  (collectively, "Jeopardy Event"), then the parties shall
use their best efforts to meet forthwith and attempt to negotiate an amendment
to this Stock Purchase Agreement to remove or negate the effect of the Jeopardy
Event.  In the event the parties are unable to negotiate such an amendment
within thirty (30) days following written notice by either party of the Jeopardy
Event, then Purchaser may cancel this Agreement immediately upon written notice
("Cancellation Option").

     9.2  EXERCISE OF CANCELLATION OPTION.  In the event Purchaser exercises the
Cancellation Option described above, it shall so notify Company in writing and
each party shall return forthwith all originals and copies of any financial or
other records, instruments, or other documents it has received from the other
party and, except as provided in this Agreement, all of the parties' respective
rights and obligations hereunder shall terminate immediately.  Notwithstanding
the foregoing, the parties' respective obligations under Section 6.2 above shall
survive Purchaser's exercise of said Cancellation Option.

10.  MISCELLANEOUS

to perform its obligations hereunder (in any or all of which cases Purchaser
shall remain liable and responsible for the performance of all of its

Section 10.4 shall be null and void.

     10.5 COUNTERPARTS.  This Stock Purchase Agreement, and any amendments

original document, but which together shall constitute one and the same
instrument.

     10.8 GOVERNING LAW.  This Stock Purchase Agreement shall be governed by and
construed in accordance with the laws of the State of California.

     10.9 AMENDMENT.  This Stock Purchase Agreement may be amended at any time
by agreement of the parties, provided that any amendment shall be in writing and
executed by all parties.

     10.10     SPECIFIC PERFORMANCE.  Sellers acknowledge, and agree with
Purchaser that, in the event either Seller terminates this Stock Purchase
Agreement or otherwise fails to close, Purchaser would be irreparably damaged
thereby and that monetary damages would not provide an adequate remedy. 
Accordingly, it is agreed that, in addition to any other remedies that Purchaser
may have at law or in equity, Purchaser shall be entitled to specific
performance and injunctive relief to prevent 


                                        27
<PAGE>


such a breach and specifically to enforce the terms and provisions hereof in 
any action instituted in a court of competent jurisdiction.

     10.11     SEVERABILITY.  If any provision of this Stock Purchase Agreement
is held by a court of competent jurisdiction to be invalid or unenforceable, the
remaining provisions will nevertheless continue in full force and effect, unless
such invalidity or unenforceability would defeat an essential business purpose
of this Stock Purchase Agreement.

     10.12     FEES AND EXPENSES.  Except for accountant's fees directly related
to the audit of the Company, which fees the parties agree are to be paid by
Purchaser, or as otherwise explicitly set forth otherwise in writing signed by
the parties, Sellers and Purchaser agrees to bear their own expenses including,
without limitation, attorneys' fees in connection with the preparation of this
Stock Purchase Agreement and the transactions contemplated hereby.  Sellers
further agree that all legal fees exceeding $30,000 incurred in connection with
this Stock Purchase Agreement and the transactions contemplated hereby shall be
the responsibility of Sellers and not Company.

     10.13     EXHIBITS AND SCHEDULES.  All exhibits and schedules attached to
this Stock Purchase Agreement are incorporated herein by this reference and all
references herein to "Stock Purchase Agreement" shall mean this Stock Purchase
Agreement together with all such exhibits and schedules, and all ancillary
agreements to be delivered at Closing.

     10.14     SURVIVAL OF INDEMNIFICATION, REPRESENTATIONS AND WARRANTIES. 
Except as expressly stated to the contrary herein, the indemnifications,
representations and warranties of the parties contained in this Stock Purchase
Agreement or in any certificate or document delivered pursuant to the provisions
hereof shall survive the Closing Date for a period of three (3) years and shall
not be affected by any investigation made by or on behalf of Purchaser, Company
or Sellers.

     10.15     TIME OF ESSENCE.  Time is expressly made of the essence of this
Stock Purchase Agreement and each and every provision hereof of which time of
performance is a factor.

     10.16     WAIVERS.  No waiver by any party, whether express or implied, of
its rights under any provision of this Agreement shall constitute a waiver of
the party's rights under such provisions at any other time or a waiver of the
party's rights under any other provision of this Stock Purchase Agreement.  No
failure by any party to take any action against any breach of this Stock
Purchase Agreement or default by another party shall constitute a waiver of the
former party's right to enforce any provision of this Stock Purchase Agreement
or to take action against such breach or default or any subsequent breach or
default by the other party.  To be effective any waiver must be in writing and
signed by the waiving party.

     10.17     ATTORNEYS' FEES.  Subject to the rights and obligations of the
parties set forth in Article 8, should any party institute any action or
procedure to enforce this Stock Purchase Agreement or any provision hereof, or
for damages by reason of any alleged breach of this Stock Purchase Agreement or
of any provision hereof, or for a declaration of rights hereunder (including
without limitation arbitration), the prevailing party in any such action or
proceeding shall be entitled 


                                       28
<PAGE>


to receive from the other party all costs and expenses, including without 
limitation reasonable attorneys' fees, incurred by the prevailing party in 
connection with such action or proceeding.

     10.18     ARBITRATION.  The parties firmly desire to resolve all disputes
arising hereunder without resort to litigation in order to protect their
respective business reputations and the confidential nature of certain aspects
of their relationship.  Accordingly, any controversy or claim arising out of or
relating to this Agreement, or the breach thereof, shall be settled by
arbitration as set forth below.

          (a)  All disputes which in any manner arise out of or relate to this
Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 10.18.  Either
party may commence arbitration by sending a written demand for arbitration to
the other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

          (b)  The parties stipulate to arbitration before a single, mutually
agreed upon arbitrator sitting on the Los Angeles, California Judicial
Arbitration Mediation Services (JAMS) panel.  In the event that the parties are
unable to agree upon the person chosen as arbitrator within 30 days of the
demand for arbitration, the arbitrator shall be selected in the sole discretion
of the JAMS administrator.  The arbitrator shall be a member of the California
bar.

          (c)  The parties shall share all costs of arbitration.  The prevailing
party shall be entitled to reimbursement by the other party of such party's
attorneys' fees and costs and any arbitration fees and expenses incurred in
connection with the arbitration hereunder.

          (d)  The substantive law of the State of California shall be applied
by the arbitrator.  All proceedings in arbitration shall be in accordance with
the California Code of Civil Procedure, as amended, and the parties shall have
the right to legal discovery in any matter submitted to arbitration in
satisfaction of California Code of Civil Procedure Section 1283.05, as permitted
by California Code of Civil Procedure Section 1283.1(b).

          (e)  Arbitration shall take place in Los Angeles, California unless
the parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable thereafter, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

          (f)  All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement.  The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

          (g)  Notwithstanding the foregoing, because time is of the essence of
this Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, 


                                      29
<PAGE>


preliminary injunction, or other similar equitable relief.

          (h)  The decision and award of the arbitrator shall be kept
confidential by the parties to the greatest extent possible.  No disclosure of
such decision or award shall be made by the parties except as required by law or
as necessary or appropriate to effect the enforcement thereof.

          (i)  Should either party institute any action or procedure to enforce
this Agreement or any provision hereof, or for damages by reason of any alleged
breach of this Agreement or of any provision hereof, or for a declaration of
rights hereunder (including without limitation arbitration), the prevailing
party in any such action or proceeding shall be entitled to receive from the
other party all costs and expenses, including without limitation reasonable
attorneys' fees, incurred by the prevailing party in connection with such action
or proceeding.


     10.19     CONSTRUCTION.  The parties have participated jointly in the
negotiation and drafting of this Stock Purchase Agreement and in the event of
any ambiguity or question of intent or interpretation, no presumption or burden
of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any of the provisions of this Stock Purchase Agreement.

     10.20     FURTHER ASSURANCES.  The parties shall take such actions and
execute and deliver such further documentation as may reasonably be required in
order to give effect to the transactions contemplated by this Stock Purchase
Agreement and the intentions of the parties hereto.

Act which has been filed by Prospect and declared effective by the SEC or (b) in
the opinion of counsel for Prospect, no such registration statement or
post-effective amendment is required, or (c) the SEC has first issued a "no
action" letter regarding any such proposed disposition of the Prospect Common.

       12.9   DISPUTE.  The parties firmly desire to resolve all disputes
arising hereunder without resort to litigation in order to protect their
respective business reputations and the confidential nature of certain aspects
of their relationship.  Accordingly, any controversy or claim arising out of or
relating to this Agreement, or the breach thereof, shall be settled by
arbitration as set forth below.

              (a)    All disputes which in any manner arise out of or relate to
this Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 12.9.  Either
party may commence arbitration by sending a written demand for arbitration to
the other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

              (b)    The parties stipulate to arbitration before a single,
mutually agreed upon arbitrator sitting on the Los Angeles, California Judicial
Arbitration Mediation Services (JAMS) panel.  In the event that the parties are
unable to agree upon the person chosen as arbitrator within 30 days of the
demand for arbitration, the arbitrator shall be selected in the sole discretion
of the JAMS administrator.  The arbitrator shall be a member of the California
bar.

              (c)    The parties shall share all costs of arbitration.  The
prevailing party shall be entitled to reimbursement by the other party of such
party's attorneys' fees and costs and any arbitration fees and expenses incurred
in connection with the arbitration hereunder.

              (d)    The substantive law of the State of California shall be
applied by the arbitrator.  All proceedings in arbitration shall be in
accordance with the California Code of Civil Procedure, as amended, and the
parties shall have the right to legal discovery in any matter submitted to
arbitration in satisfaction of California Code of Civil Procedure Section
1283.05, as permitted by California Code of Civil Procedure Section 1283.1(b).

              (e)    Arbitration shall take place in Los Angeles, California
unless the parties otherwise agree.  As soon as reasonably practicable, a
hearing with respect to the dispute or matter to be resolved shall be conducted
by the arbitrator.  As soon as reasonably practicable thereafter, the arbitrator
shall arrive at a final decision, which shall be reduced to writing, signed by
the arbitrator and mailed to each of the parties and their legal counsel.

              (f)    All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement.  The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

              (g)    Notwithstanding the foregoing, because time is of the
essence of this Agreement, the parties specifically reserve the right to seek a
judicial temporary restraining order, preliminary injunction, or other similar
equitable relief.

confidential by the parties to the greatest extent possible.  No disclosure of
such decision or award shall be made by the parties except as required by law or
as necessary or appropriate to effect the enforcement thereof.

              (i)    Should either party institute any action or procedure to
enforce this Agreement or any provision hereof, or for damages by reason of any
alleged breach of this Agreement or of any provision hereof, or for a
declaration of rights hereunder (including without limitation arbitration), the
prevailing party in any such action or proceeding shall be entitled to receive
from the other party all costs and expenses, including without limitation
reasonable attorneys' fees, incurred by the prevailing party in connection with
such action or proceeding.

       12.10  SEVERABILITY.  If for any reason whatsoever, any one or more of
the provisions of this Agreement shall be held or deemed to be inoperative,
unenforceable or invalid as applied to any particular case or in all cases, such
circumstances shall not have the effect of rendering such provision invalid in
any other case or of rendering any of the other provisions of this Agreement
inoperative, unenforceable or invalid.

       12.11  THIRD PARTY BENEFICIARIES.  Except as expressly set forth herein,
no provision of this Agreement, including the Exhibits and Schedules hereto, is
intended or should be construed to create any third party beneficiaries or to
give any rights, including rights of subrogation, to any person other than the
parties to this Agreement.

       12.12  BEST EFFORTS; FURTHER ASSURANCES.  Subject to the terms and
conditions of this Agreement, each party shall use its best efforts to take, or
cause to be taken, all action and to do, or cause to be done, all things
necessary, proper or advisable consistent with applicable laws and regulations
to consummate the transactions contemplated by this Agreement as promptly as
possible.  The parties hereto shall do and perform or cause to be done and

borne by Seller, and thereafter shall be borne by Buyer.  If any material

to the Closing, other than use, wear or loss in the ordinary course of the
Business, Seller shall give written notice to Buyer as soon as practicable
after, but in any event within five (5) calendar days of, discovery of such
damage or destruction, the amount of insurance, if any, covering such Assets and

would be ineffective or would affect the rights with respect thereto so that
Buyer would not receive all such rights, Seller will cooperate with Buyer in all
reasonable respect without liability to Seller, to provide to Buyer the benefits
with respect to any such Asset, including without limitation enforcement for the
benefit of Buyer of any and all rights of Seller against a third party arising
out of the breach or cancellation by such third party or otherwise. If any Asset
determined in the sole discretion of Buyer to be material to the transaction is
not transferable pursuant to the provisions of this Section, Buyer may terminate
this Agreement.

              (c)    COOPERATION.  The indemnified party shall cooperate in all
reasonable respects with the indemnifying party in the investigation, trial and
defense of any lawsuit or action that may be subject to this Section 10.3 and
any appeal arising thereform; PROVIDED, HOWEVER, that the indemnified party may,
at its own cost, participate in the investigation, trial and defense of such
lawsuit or action and any appeal arising therefrom.  The parties shall cooperate
with each other in any notivications to insurers.

              (d)    DEFENSE OF CLAIMS.  If a claim for Damages (a "Claim") is
to be made by a party entitled to indemnification hereunder against the
indemnifying party, the party claiming such indemnification shall, subject to
Section 10.3, give written notice (a "Claim Notice") to the indemnification may
be sought under this Section 10.3.  If any lawsuit or enforcement action is
filed against any party entitled to the benefit of indemnity hereunder, written
notice thereof shall be given to the indemnifying party as promptly as
practicable (and in any event within fifteen (15) calendar days after the
service of the citation or summons).  The failure of any indemnified party

<PAGE>

to give timely notice hereunder shall not affect rights to indemnification
hereunder, except to the extent that the indemnifying party demonstrates actual
damage caused by such failure.  After such notice, if the indemnifying party
shall acknowledge in writing to the indemnified party that the indemnifying
party shall be obligated under the terms of its indemnity hereunder in
connection with such lawsuit or action, then the indemnifying party shall be
entitled, if it so elects, (i) to take control of the defense and investigation
of such lawsuit or action, (ii) to employ and engage attorneys of its own choice
to handle and defend the same, at the indemnifying party's cost, risk and
expense unless the named parties to such action or proceeding include both the
indemnifying party and the indemnified party and the indemnified party has been
advised in writing by counsel that there may be one or more legal defenses
available to such indemnified party that are different from or additional to
those available to the indemnifying party, and (iii) to compromise or settle
such claim, which compromise or settlement shall be made only with the written
consent of the indemnified party, such consent not to be unreasonably withheld.
If the indemnifying party fails to assume the defense of such claim within
fifteen (15) calendar days after receipt of the Claim Notice, the indemnified
party against which such claim has been asserted will (upon delivering notice to
such effect to the indemnifying party) have the right to undertake, at the
indemnifying party's cost and expense, the defense, compromise or settlement of
such claim on behalf of and for the account and risk of the indemnifying party;
PROVIDED, HOWEVER, that such Claim shall not be compromised or settled without
the written consent of the indemnifying party, which consent shall not be
unreasonably withheld.  In the event the indemnified party assumes the defenseof
the lcaim, the indemnified party will keep the indemnifying party reasonably
informed of the progress of any such defense, compromise or settlement.  The
indemnifying party shall be liable for any settlement of any action effected
pursuant to and in accordance with this Section 10.3 and for any final judgment
(subject to any right of appeal), and the indemnifying party agrees to indemnify
and hold harmless an indemnified party from and against any Damages by reason of
such settlement or judgment.

              (e)    BROKERS AND FINDERS.  Pursuant to the provisions of this
Section 10.3, each of Buyer and Seller shall indemnify, hold harmless and defend
the other party from the payment of any and all broker's and finder's expenses,
commissions, fees or other forms of compensation that may be due or payable from
or by the indemnifying party, or may have been earned by any third party acting
on behalf of the indemnifying party in connection with the negotiation and
execution hereof and the consummation of the transactions contemplated hereby.

reeipt by Buyer or Seller of any funds, deposits or other proceeds properly
belonging to the other party hereunder, said funds shall be deposited by the
recipient in the account designated by the other party for such purpose.

       Section 10.6  INSURANCE.  Seller agrees to maintain and pay all premiums
on "tail" coverage for its malpractice insurance policies for a period of 24
months after the Closing. One-


                                          23

half of such cost will be paid at Closing by Seller; the remaining cost will be

concerning the business of Clinics, its manner of operation or other
confidential data of any kind, nature, or description, the parties hereto
stipulating that as between them, the same are important, material and
confidential trade secrets and affect the successful conduct of the business of
Clinics and its goodwill.

contractor of West makes any derogatory remarks regarding Buyer to any plan
member, plan member's employer, health plan or health maintenance organization.

              (d)    If any term or provision of this Section is determined to
be illegal, unenforceable or invalid in whole or in part for any reason, such
illegal, unenforceable or invalid provision or part thereof shall be stricken
from this Agreement, and such provision shall not affect the legality,
enforceability or validity of the remainder of this Agreement.  If any provision
or part thereof of this Section is stricken from this Agreement, in accordance

                                          24

similar in tenor to the stricken provision as is legally possible.

                               PURCHASE PRICE OF ASSETS

          3.1 CONSIDERATION: PAYMENT OF PURCHASE PRICE.

               (a)  Subject to the terms and conditions of this Agreement and in
full consideration of the sale and transfer of the Assets, Prospect Holdings
shall pay to PrimeCare International a total purchase price in cash and stock,
as set forth below (the "Asset Purchase Price"), as follows:

                    (i)  Prospect Holdings shall pay Four Hundred Seventy-Five
Thousand ($475,000.00) ("PrimeCare Down Payment") to PrimeCare International at
the Closing, as defined in Section 7 herein, payable by way of a wire transfer
of immediately available funds into a deposit account designated in writing by
PrimeCare International prior to the Closing Date;

                    (ii) Prospect Holdings will execute and deliver to PrimeCare
International at the Closing, a promissory note in the principal amount of Five

                                          3
<PAGE>

($500,000.00), made payable to PrimeCare International, with interest thereon
payable at 8% per annum, and principal due in two (2) equal installments of Two
Hundred Fifty Thousand Dollars ($250,000.00) each, together with accrued
interest thereon, payable at ninety (90) days and one hundred eighty (180) days
from the Closing, the form of which is attached hereto as Exhibit 3.1(a)(ii)
(the "Note") (the obligations of Prospect Holdings under the Note are
subordinated, in accordance with that certain Subordination Agreement of even
date herewith, to the obligations under a note and security agreement made by
Prospect Holdings in favor of Imperial Bank, a California banking corporation);
and

                    (iii) Prospect Holdings will issue to PrimeCare
International, two hundred thousand (200,000) shares of Prospect Holdings's
$0.01 par value common stock, as adjusted herein (the "Shares").  In the event
that during the Equitable Adjustment Period (as defined below), Prospect
Holdings issues any shares of common stock at a price less than Five Dollars
($5.00) per share or issues any other security that can be converted into common
stock (including, but not limited to, preferred stock, warrants, or options)
with a strike price/exercise price/effective conversion price of less than Five
Dollars ($5.00) per share ("Market Price or Exercise Price"), then Prospect
Holdings shall immediately issue to PrimeCare International the number of shares
of common stock (at no additional consideration) determined as follows
("Equitable Adjustment"):  (a) one million (1,000,000) divided by the Market
Price or Exercise Price, less (b) two hundred thousand (200,000).  In the event
of further issuances of common stock or additional securities as described above
during the Equitable Adjustment Period, as to which Equitable Adjustment is
required, the Shares shall be subject to further Equitable Adjustment using the
same formula except that two hundred thousand (200,000) shall be replaced by the
total number of shares then issued to, and held by, PrimeCare International.
For purposes of this Section 3.1(a)(iii), "Equitable Adjustment Period" shall
mean the period beginning on the Closing Date and ending on the earlier of:  (i)
three (3) years from the Closing Date, or (ii) the date of an initial public
offering of Prospect Holdings stock ("IPO").  In the event of an IPO, Prospect
Holdings shall use reasonable efforts to avoid any restrictions on PrimeCare
International to freely transfer or sell the Shares, except as required by
Prospect Holdings lender or underwriters.  Notwithstanding the above, the
following issuances of securities shall not result in an Equitable Adjustment:
(i) the issuance of common stock pursuant to a conversion subsequent to the
Closing of convertible securities issued prior to the Closing; (ii) the
issuances of securities in consideration, in part or in whole, of services
previously rendered or to be rendered (including, without limitation, securities
issued as part of an employee incentive plan), so long as such issuances during
the Equitable Adjustment Period total less than five percent (5%) of the issued
and outstanding stock of Prospect Holdings on the Closing Date; and


                                          4
<PAGE>

(iii) the issuance of additional securities by reason of a third-party's
equitable adjustment rights.

               (b)  Subject to the terms and conditions of this Agreement and in
full consideration of the transfer of Member Responsibility, the transfer and
assignment of the Provider Agreements, and the transfer and sale of Antelope
Valley Group Assets, Sierra Group shall pay to Antelope Valley Group a total
acquisition price of Twenty-Five Thousand Dollars ($25,000.00) ("Contract
Acquisition Price") at the Closing, as defined in Section 7 herein, payable by
way of a wire transfer of immediately available funds into a deposit account
designated in writing by PrimeCare International prior to the Closing Date.

               (c) The parties acknowledge that David Jensen, M.D. ("Dr.
Jensen") has entered into that certain Affiliation Agreement dated April 1,
1997, that certain Provider Service Agreement dated January 1, 1998, and that
certain Consent to Assignment of Provider Service Agreement and Affiliation
Agreement dated February 25, 1998.  The parties agree that, notwithstanding the
assignment of the Affiliation Agreement as set forth in this Agreement,
PrimeCare International shall continue to be responsible for payments made to
Dr. Jensen referred to in the Affiliation Agreement as "Variable Consideration
Fee", which PrimeCare International and Prospect agree shall be equal to
Twenty-Five Thousand Dollars ($25,000.00) (the "Prepayment Fee").  On the date
of the first payment due under the Note by Prospect Holdings ("First Date"),
Prospect Holdings shall pay to PrimeCare International an amount computed as
follows:  the Prepayment Fee multiplied by a fraction, the numerator of which is
(i) the total number of members assigned to Dr. Jensen by Antelope Valley Group
or Sierra Group on the First Date, less (ii) one thousand nine hundred
twenty-one (1,921) (being the number of members assigned to Dr. Jensen by
Antelope Valley Group as the base for determining the Variable Consideration
Fee), and the denominator of which is six hundred (600).  On the date of the
second (final) payment due under the Note by Prospect Holdings, Prospect
Holdings shall pay to PrimeCare International an amount computed as set forth
above, less the amount of any payment previously made as set forth above.
Prospect Holdings and Sierra shall provide to PrimeCare International and
Antelope Valley Group capitation reports and enrollment data regarding the total
members assigned to Dr. Jensen during the periods set forth above.

          3.2 FAIR MARKET VALUE.  The parties agree that the Asset Purchase
Price reflects the fair market value of the Assets, and the Contract Acquisition
Price reflects the fair market value of the transfer of Member Responsibility,
the Provider Agreements, and Antelope Valley Group Assets.  The parties agree no
consideration is or will be paid for the value of any referrals (direct or
indirect) to or from Sierra Group or Antelope Valley Group, or any of their
affiliates.

          3.3 SALES AND TRANSFER TAXES.  Any sales and transfer taxes related to
this transaction shall be borne by PrimeCare International or Antelope Valley
Group, as the case may be.

          3.4 THE SHARES.  PrimeCare International agrees and acknowledges that
the Shares to be issued pursuant to this Agreement are "restricted securities,"
as that term is defined under the Securities Act of 1933, as amended, and are
not freely tradeable.  Prior to issuing the Shares to PrimeCare International,
PrimeCare International and Prospect Holdings will execute a Stockholder
Representation Agreement in the form of that attached hereto as Exhibit 3.4, in
order to comply with applicable federal and State securities laws.  The
Stockholder Representation Agreement shall contain mutually acceptable
representations, warranties and covenants, including an agreement not to sell,
transfer, or make any other disposition of the Shares unless and until (a) such
Shares are included in a registration statement or a post-effective amendment
under the Securities Act which has been filed by Prospect Holdings and declared
effective by the SEC, or (b) in the opinion of counsel for Prospect Holdings, no
such registration statement or post-effective amendment is required, or (c) the
SEC has first issued a "no action" letter regarding any such proposed
disposition of the Shares.  Further, the Stockholder Representation Agreement
will contain mutually acceptable registration rights.

Group by or from Antelope Valley Group or PrimeCare International, as the case
may be, are true, correct and complete copies of what they purport to be,(iii)
to their actual knowledge, neither Antelope Valley Group nor PrimeCare
International has failed to state or disclose any material fact in connection
with the transactions contemplated by this Agreement, and (iv) neither Antelope
Valley Group nor PrimeCare International, as the case may be, knows of any fact
or has misrepresented any facts concerning its ability, financial or otherwise,
to consummate the transactions contemplated by this Agreement or that would
otherwise materially adversely affect Prospect Holding's decision to acquire the
Assets, or Sierra Group's decision to acquire the Antelope Valley Group Assets,
assume the Provider Agreements, and accept Member Responsibility.

          4.22 NAMES.  Neither PrimeCare International nor Antelope Valley Group
has operated during the past five (5) years under any name other than as set
forth in the preamble above.

          4.23 COVENANT NOT TO COMPETE.

               (a) The parties acknowledge and agree that Antelope Valley Group
and PrimeCare International, as the case may be, are parties to certain
covenants not to compete related to that certain Stock Purchase Agreement dated
June 14, 1996 ("Provider Covenants").  Such Provider Covenants are not
assignable to Sierra Group or Prospect Holdings.  However, in the event of an
alleged breach of a Provider Covenant by a party at or after the Effective Time
and upon the written request of Prospect Holdings, PrimeCare International shall
exercise any and all remedies available to PrimeCare International at the
direction and supervision of Prospect Holdings, although PrimeCare International
makes no representation or warranty regarding the successfulness of any
litigation or PrimeCare International's legal right to enforce such covenants.
PrimeCare International and Prospect Holdings shall mutually agree upon the
costs and fees to be incurred and the actions to be taken in the exercise of
such remedies, and Prospect Holdings agrees to pay all costs (including all
attorneys' fees) and all fees associated with the exercise of remedies by
PrimeCare International in advance.  In the event, PrimeCare International and
Prospect Holdings cannot mutually agree upon the actions to be taken in the
exercise of the remedies discussed above, PrimeCare International shall
undertake all actions instructed by Prospect Holdings so long as Prospect
Holdings pays all costs (including


                                          14
<PAGE>

attorneys' fees) and all fees associated with such instructions in advance, and
so long as such actions do not, in the reasonable opinion of PrimeCare
International, materially and adversely affect the financial condition of
PrimeCare International.  The parties hereto acknowledge and agree that a breach
by PrimeCare International of the obligation to enforce such covenants will
cause irreparable damage to Prospect Holdings, the exact amount of which will be
difficult to ascertain, and that remedies at law for any such breach will be
inadequate.  Accordingly, PrimeCare International agrees that if it breaches the
obligation to enforce such covenants as set forth above, then Prospect Holdings
shall be entitled to injunctive relief, and PrimeCare International agrees not
to assert in any proceeding that Prospect Holdings has an adequate remedy at
law.

               (b) The parties further acknowledge and agree that litigation has
been undertaken to enforce the above-described covenants not to compete, and
PrimeCare International agrees, at its sole cost and expense, to pursue such
litigation as it reasonably determines.  Any recovery from such litigation shall
be the sole property of PrimeCare International.  Prospect Holdings and Sierra
Group agree to reasonably cooperate (including making officers and directors
familiar with this Agreement available to testify) with PrimeCare International
in such litigation, in order to assist PrimeCare International in establishing
the damages (including the reduction in the value of the assets and rights
transferred in this Agreement) caused by (i) the loss of revenue related to the
actions of the physicians violating the above-described covenant, (ii) the risk
of instability to the Practice caused by the withdrawal of such physicians,
(iii) the damage caused by the loss of a large percentage of available
pediatricians to the Practice, and (iv) the overall damages caused by the breach
of the above-described covenant not to compete by such physicians.

or consulting agreement with any physician, hospital, nursing facility, home

referrals to or from such medical groups, to provide services, lease space,
lease equipment or engage in any other venture or activity, other than pursuant

from operations or credit available to pay its obligations under the Note as
such obligations become due.  Further, Prospect Holdings is not in default under
any line of credit, promissory note, or security agreement nor has any event
occurred that, with notice or the passage of time, or both, would constitute a
default by Prospect Holdings under any such credit agreements, and there is no
basis for any of the other parties to such credit agreements to assert that
Prospect Holdings is in default thereunder.

                             CERTIFICATE OF INCORPORATION

                                          OF

                                   MED-SEARCH, INC.


     1.   NAME:  The name of the corporation is Med-Search, Inc. (hereafter, the
"corporation").

     2.   REGISTERED OFFICE:  The address of the registered office of the
corporation in the State of Delaware is 1013 Centre Road, in the City of
Wilmington, County of New Castle, and its registered agent is Corporate Agents,
Inc.

     3.   PURPOSE:  The purpose of the corporation is to engage in any lawful
act or activity for which a corporation may now or hereafter be organized under
the General Corporation Law of the State of Delaware as set forth in Title 8 of
the Delaware Code (the "GCL").

     4.   CORPORATE STOCK:
          a.   The total number of shares of stock which the corporation shall
have authority to issue is Thirty Million (30,000,000) shares, consisting of
Twenty-nine Million (29,000,000) shares of Common Stock, having a par value of
$.01 per share, and One Million (1,000,000) shares of Preferred Stock, having a
par value of $.01 per share.

          b.   Shares of the Preferred Stock of the corporation may be issued
from time to time in one or more classes or series, each of which class or
series shall have such distinctive designation or title as shall be fixed by the
Board of Directors of the corporation (the "Board of Directors") prior to the
issuance of any shares thereof.  Each such class or series of Preferred Stock
shall have such voting powers, full or limited, or no voting powers, and such
preferences and relative, participating, optional or other special rights and
such qualifications, limitations or restrictions thereof, as shall be stated in
such resolution or resolutions providing for the issue of such class or series
of Preferred Stock as may be adopted from time to time by the Board of Directors
prior to the issuance of any shares thereof pursuant to the authority hereby
expressly vested in it, all in accordance with the laws of the State of
Delaware.  The number of authorized shares of Preferred Stock may be increased
or decreased (but not below the number of shares thereof then outstanding) by
the affirmative vote of the holders of a majority of the Common Stock, without a
vote of the holders of the Preferred Stock, or of any class or series thereof,
unless a vote of any such holders is required pursuant to the certificate or
certificates establishing the class or series of Preferred Stock.


<PAGE>

          c.   The shares of Common Stock and Preferred Stock shall be issued
only as fully paid and non-assessable shares.

          d.   Holders of shares of Common Stock shall be entitled to one (1)
vote for each share held of record.  Shares of the Common Stock shall have no
preference over any other shares of capital stock of the corporation with
respect to distribution of assets on dissolution or liquidation or with respect
to payment of dividends.

     5.   DIRECTORS:
          a.   The business and affairs of the corporation shall be managed by
or under the direction of the Board of Directors consisting of an odd number of
not less than three (3) directors nor more than seven (7) directors, the exact
number of directors to be determined from time to time by resolution adopted by
the Board of Directors.  The directors shall be divided into three classes,
designated Class I, Class II and Class III.  The term of the initial Class I
directors shall terminate on the date of the 1994 annual meeting of
stockholders; the term of the initial Class II directors shall terminate on the
date of the 1995 annual meeting of stockholders and the term of the initial
Class III directors shall terminate of the date of the 1996 annual meeting of
stockholders.  At each annual meeting of stockholders beginning in 1994,
successors to the class of directors whose term expires at that annual meeting
shall be elected for a three-year term.  If the number of directors is changed,
any increase or decrease shall be apportioned among the classes so as to
maintain the number of directors in each class as nearly equal as reasonably
possible, and any additional directors of any class elected to fill a vacancy
resulting from an increase in such class shall hold office for a term that shall
coincide with the remaining term of that class, but in no case will a decrease
in the number of directors shorten the term of any incumbent directors.  A
director shall hold office until the annual meeting for the year in which his
term expires and until his successor shall be elected and shall qualify,
subject, however, to prior death, resignation, retirement, disqualification or
removal from office.  Any vacancy on the Board of Directors, howsoever
resulting, shall be filled only by a majority of the directors then in office,
even if less than a quorum, or by a sole remaining director and not by the
stockholders.  Any director elected to fill a vacancy shall hold office for a
term that shall coincide with the terms of the class to which such director
shall have been elected.

          b.   Subject to the rights, if any, of the holders of shares of
Preferred Stock then outstanding, any or all of the directors of the corporation
may be removed from office at any time, for cause only, by the affirmative vote
of the holders of seventy-five percent (75%) of the outstanding shares of the
corporation then entitled to vote generally in the election of directors,
considered for purposes of this Paragraph 5(b) as one class.

          c.   Notwithstanding the foregoing, whenever the holders of any one or
more classes or series of Preferred Stock issued by the corporation shall have
the right, voting separately by class or series, to elect directors at an annual
or special meeting of stockholders, the 


                                          2
<PAGE>

election, term of office, filling of vacancies and other features of such 
directorships shall be governed by the terms of this Certificate of 
Incorporation or the resolution or resolutions adopted by the Board of 
Directors pursuant to Paragraph 4(b) applicable thereto, and such directors 
so elected shall not be divided into classes pursuant to this Paragraph 5 
unless expressly provided by such terms.

     6.   STOCKHOLDERS:
          a.   SPECIAL MEETINGS:  Special meetings of the stockholders for any
purpose or purposes may be called at any time only by the Board of Directors,
the Chairman of the Board, or by the Chief Executive Officer or President of the
corporation.

          b.   MEETINGS LOCATION:  Meetings of stockholders may be held within
or without the State of Delaware, as the Bylaws may provide.  The books of the
corporation may be kept (subject to any provision contained in the GCL) outside
the State of Delaware at such place or places as may be designated from time to
time by the Board of Directors or in the Bylaws of the corporation.

          c.   POWER OF STOCKHOLDERS:  Bylaws may be adopted, amended, or
repealed by the affirmative vote of the holders of seventy-five percent (75%) of
the outstanding shares of the corporation except as otherwise provided by law or
by this Certificate of Incorporation.

          d.   POWER OF DIRECTORS:  Subject to the rights of stockholders as
provided in Paragraph 6(c) to adopt, amend or repeal Bylaws and except as
otherwise provided in Paragraph 6(c), Bylaws may be adopted, amended or repealed
by the Board of Directors at any regular or special meeting thereof.

          e.   ELECTION OF DIRECTORS BY BALLOT:  Election of directors need not
be by ballot unless a stockholder demands election by ballot at the meeting and
before the voting begins.

          f.   VOTE OF STOCKHOLDERS:  Any action required or permitted to be
taken at any annual or special meeting of stockholders may be taken only upon
the vote of the stockholders at an annual or special meeting duly noticed and
called, as provided in the Bylaws of the corporation, and may not be taken by a
written consent of the stockholders pursuant to the GCL unless such action by
consent shall be authorized by resolution of the Board of Directors.

     7.   LIMITATION ON LIABILITY OF DIRECTORS:  No director of the corporation
shall be personally liable to the corporation or its stockholders for monetary
damages for any breach of fiduciary duty by such director as a director.
Notwithstanding the foregoing sentence, a director shall be liable to the extent
provided by applicable law (i) for any breach of the director's duty of loyalty
to the corporation or its stockholders, (ii) for acts or omissions not in good
faith or which involve intentional misconduct or a knowing violation of law,
(iii) pursuant to Section 174 of the


                                          3
<PAGE>

GCL or (iv) for any transaction from which the director derived an improper
personal benefit.  If, and to the extent final legal determination is ever made
that and for so long as Section 204(a)(10) or Section 317 of the California
Corporations Code (as now or hereafter in effect) are applicable to the
corporation, the provisions of Paragraphs 7 and 8 hereof shall apply only to the
extent necessary and permissible under the GCL so that such Paragraphs shall
comply with Sections 204(a)(10) and 317.  No amendment to or repeal of this
Paragraph 7 shall apply to or have any effect on the liability or alleged
liability of any director of the corporation for or with respect to any acts or
omissions of such director occurring prior to such amendment or repeal.

     8.   INDEMNITY:
          a.   RIGHT TO INDEMNIFICATION:  Each person who was or is made a party
or is threatened to be made a party to or is otherwise involved in any action,
suit or proceeding, whether civil, criminal, administrative or investigative
("proceeding"), by reason of the fact that he or she is or was a director or
officer of this corporation or, while a director or officer of this corporation,
is or was serving at the request of this corporation as a director, officer,
employee or agent of another corporation or of a partnership, joint venture,
trust or other enterprise, including service with respect to employee benefit
plans ("indemnitee"), whether the basis of such proceeding is alleged action in
an official capacity as a director, officer, employee or agent, or in any other
capacity while serving as a director, officer, employee or agent, shall be
indemnified and held harmless by this corporation to the fullest extent
authorized by the GCL against all expense, liability and loss (including
attorneys' fees, judgments, fines, excise taxes under the Employee Retirement
Income Security Act of 1974 or penalties, and amounts paid or to be paid in
settlement) reasonably incurred or suffered by indemnitee in connection
therewith and such indemnification shall continue as to any indemnitee who has
ceased to be director, officer, employee or agent and shall inure to the benefit
of his or her heirs, executors or administrators; provided, however, that except
as provided in Paragraph 8(d) with respect to proceedings to enforce rights of
indemnification this corporation shall indemnify any indemnitee seeking
indemnification in connection with a proceeding (or part thereof) initiated by
such indemnitee only if such proceeding (or part thereof) was authorized by the
Board of Directors of this corporation.  The right to indemnification conferred
in these Paragraphs 8(a) - (e) shall be a contract right and shall include the
right to be paid by this corporation the expenses incurred in defending such
proceeding in advance of its final disposition; provided, however, that, if the
GCL requires, the payment of such expenses incurred by indemnitee in his or her
capacity as a director or officer (and not in any other capacity in which
service was or is rendered by an indemnitee while a director or officer,
including, without limitation, service with respect to an employee benefit plan)
in advance of the final disposition of such proceeding, shall be made only upon
delivery to this corporation of an undertaking, by or on behalf of such
indemnitee, to repay all amounts so advanced if it shall ultimately be
determined by final judicial determination from which there is no right to
appeal that such indemnitee is not entitled to be indemnified under these
Paragraphs 8(a) - (e) or otherwise.  This corporation may, by action of its
Board of Directors, provide indemnification to employees and agents of this
corporation and any subsidiary of this


                                          4
<PAGE>

corporation with the same scope and effect as the foregoing indemnification 
of directors and officers.

          b.   NON-EXCLUSIVITY OF RIGHTS:  The right to indemnification and the
payment of expenses incurred in defending a proceeding in advance of its final
disposition conferred in these Paragraphs 8(a) - (e) shall not be exclusive of
any right which any person may have or hereafter acquire under any statute,
provision of this Certificate of Incorporation, Bylaw, agreement, vote of
stockholders or disinterested directors or otherwise.

          c.   INSURANCE:  The corporation may maintain insurance, at its
expense, to protect itself and any director, officer, employee or agent of the
corporation or another corporation, partnership, joint venture, trust or other
enterprise against any such expense, liability  or loss, whether or not the
corporation would have the power to indemnify such person against such expense,
liability or loss under the GCL.

          d.   RIGHT OF INDEMNITEE TO BRING SUIT:  If a claim under Paragraph
(a) of this Paragraph 8 is not paid in full by the corporation within sixty days
after a written claim has been received by the corporation, except in the case
of a claim for advancement of expenses, in which case the applicable period
shall be twenty days, the indemnitee may at any time thereafter bring suit
against the corporation to recover the unpaid amount of the claim.  If
successful in whole or in part in any such suit or in a suit brought by the
corporation to recover an advancement of expenses pursuant to the terms of the
undertaking, the indemnitee shall be entitled to be paid also the expense of the
prosecuting or defending such suit.  In any suit brought by the indemnitee to
enforce a right to indemnification hereunder (but not in a suit brought by the
indemnitee to enforce a right to an advancement of expenses) it shall be a
defense that the indemnitee has not met the applicable standard of conduct set
forth in the GCL, and, in any suit by the corporation to recover an advancement
of expenses pursuant to the terms of an undertaking, the corporation shall be
entitled to recover such expenses upon a final adjudication that the indemnitee
has not met the applicable standard of conduct set forth in the GCL.  Neither
the failure of the corporation (including its Board of Directors, independent
legal counsel, or its stockholders) to have made a determination prior to the
commencement of such suit that indemnification of the indemnitee is proper in
the circumstances because the indemnitee has met the applicable standard of
conduct set forth in the GCL, nor an actual determination by the corporation
(including its Board of Directors, independent legal counsel, or its
stockholders) that the indemnitee has not met such applicable standard of
conduct, shall create a presumption that the indemnitee, has not met the
applicable standard of conduct or, in the case of such a suit brought by the
indemnitee, be a defense to such suit.  In any suit brought by the indemnitee to
enforce a right hereunder, or by the corporation to recover an advancement of
expenses pursuant to the terms of an undertaking, the burden of proving that the
indemnitee is not entitled to be indemnified or to such advancement of expenses
under this Paragraph 8(d) or otherwise shall be on the corporation.



                                          5
<PAGE>

          e.   In any suit or proceeding with respect to the corporation's
refusal to grant indemnification, (i) the corporation shall conclusively be
deemed to have acted in good faith and to have fully complied with any implied
covenant of good faith and fair dealing unless the indemnitee affirmatively
proves by clear and convincing evidence that the corporation acted or omitted to
act without any reasonable basis; and (ii) no indemnitees shall be entitled
hereunder or otherwise to consequential damages, including without limitation,
damages for inconvenience, emotional distress, lost profits, injury to privacy,
publicity, or reputation, or punitive damages, all of which are expressly
waived.

     9.   CERTAIN EXTRAORDINARY TRANSACTIONS:
          a.   Except as set forth in Paragraph 9(b) the affirmative vote of the
holders of seventy-five percent (75%) of the outstanding shares of the
corporation entitled to vote on the applicable Record Date shall be required
for:

               (i)    any merger or consolidation to which the corporation, or
               any of its subsidiaries, and an Interested Person (as hereinafter
               defined) are parties;

               (ii)   any sale, lease, exchange or other disposition by the
               corporation, or any of its subsidiaries, of all or substantially
               all of the corporation's or its subsidiaries'assets to an 
               Interested Person.

               (iii)  any purchase or other acquisition by the corporation, or
               any of its subsidiaries, of assets or stock of an Interested
               Person, the aggregate purchase price of which exceeds
               $20,000,000.00; and

               (iv)   any other transaction with an Interested Person which
               requires the approval of the stockholders of the corporation
               under the Delaware General Corporation Law, as in effect from
               time to time.

          b.   The provisions of Paragraph 9(a) shall not be applicable to any
transaction described therein if such transaction is approved by resolution of
the Board, provided that a majority of the members of the Board voting for the
approval of such transaction were duly elected and acting members of the Board
prior to the time that the person, firm or corporation, or any group thereof,
with whom such transaction is proposed, became an Interested Person.

          c.   As used in this Paragraph 9, the term "Interested Person" shall
mean any person, firm or corporation, or any group thereof, acting or intending
to act in concert, including any person directly or indirectly controlling or
controlled by or under direct or indirect common control with such person, firm,
or corporation or group, which owns of record or beneficially, directly or
indirectly, five percent (5%) or more of the shares of any class of voting
securities of the corporation.

                           OF CERTIFICATE OF INCORPORATION
                                 OF MED-SEARCH, INC.


     MED-SEARCH, INC., a corporation organized and existing under and by virtue
of the General Corporation Law of the State of Delaware (the "Corporation"),
does hereby certify that:

     1.   The name of the Corporation is Med-Search, Inc.

     2.   On March 25, 1996, the Board of Directors of the Corporation adopted
by unanimous written consent  resolutions proposing and declaring advisable
amendments to the certificate of incorporation of the Corporation as follows:

          "1.  NAME:  The name of the corporation is Prospect Medical Holdings,
Inc. (hereafter, the "corporation")."

          "4.  CORPORATE STOCK:

               a.     The total number of shares of stock which the corporation
          shall have authority to issue is Forty-One Million (41,000,000)
          shares, consisting of Forty Million (40,000,000) shares of Common
          Stock, having a par value of $.01 per share, and One Million
          (1,000,000) shares of Preferred Stock, having a par value of $.01 per
          share.  Upon the amendment of this Paragraph to read as herein set
          forth, each forty-four (44) outstanding shares of Common Stock shall
          be converted and combined into one (1) outstanding share of Common
          Stock.  No fractional shares shall be issued pursuant to this
          amendment.  Each stockholder who would otherwise be entitled to
          receive a fractional share shall receive, in lieu thereof, a cash
          payment from the Corporation determined by multiplying such fractional
          share of Common Stock by forty-four times the average last reported
          bid price of a share of previously existing Common Stock on the OTC
          Bulletin Board for the ten trading days immediately preceding the
          effective date, and upon such other terms as the officers of the
          Corporation, in their sole discretion, deem to be advisable and in the
          best interests of the Corporation."

     3.   The amendments of the certificate of incorporation herein certified
have been duly adopted by the stockholders of the Corporation in accordance with
the provisions of Sections 228 and 242 of the General Corporation Law of the
State of Delaware and any notice required to be given thereunder has been given.

shall be effective on the date this Certificate of Amendment is filed and

                                   MED-SEARCH, INC.
                                A Delaware Corporation

                                      ARTICLE I
                                  CORPORATE OFFICES

     Section 1.     REGISTERED OFFICE.  The registered office of the Corporation
in the State of Delaware shall be located at Corporate Trust Center, 1209 Orange

     Section 2.     Principal Office.  The principal office of the Corporation
shall be located at 5400 The Toledo, Suite 701, Long Beach, California, 90803

The Board of Directors (herein referred to as the "Board") is hereby granted the
full power and authority, by a resolution of a majority of the directors, to
change the principal office from one location to another.  Any such change shall
be noted in these Bylaws opposite this section, and this section may be amended
to state the new location.

     Section 3.     OTHER OFFICES.  The corporation may establish any additional
offices, at any place or places, as the Board may designate, or as the business
of the Corporation shall require.

                                      ARTICLE II
                                STOCKHOLDERS MEETINGS

     Section 1.     PLACE OF MEETING.  Meetings of the Stockholders of the
Corporation shall be held at the principal office or at such place, within or
without the State of Delaware, as may from time to time be designated for that
purpose by the Board.

     Section 2.     ANNUAL MEETINGS.  The annual meeting of the Stockholders
shall be held on such date and at such time designated, from time to time, by
resolution of the Board.

     Section 3.     SPECIAL MEETINGS.  Special Meetings of the Stockholders for
the purpose of taking any action which the Stockholders are permitted to take
under the General Corporation Law of the State of Delaware (herein, as the same
may from time to time be amended, referred to as the "General Corporation Law")
may be called at any time by the Chief Executive Officer, the President, the
Chairman of the Board or the Board.

     Section 4.     NOTICE OF MEETINGS.  Except as otherwise provided by
statute, written or printed notice of each meeting of the Stockholders of the
Corporation, whether annual or special, shall be given not less than ten or more
than sixty days prior to the date upon which the meeting 

<PAGE>

is to be held to each stockholder entitled to vote at such meeting by leaving
such notice with him personally at, or by transmitting such notice with
confirmed recorded communication, provided that delivery (including telex,
telegraph, cable or other form of recorded communication, provided that delivery
of such notice in written form is confirmed in a writing) to, his residence or
usual place of business.  If mailed, such notice shall be deemed delivered when
deposited in the United States mail in a sealed envelope addressed to the
stockholder at his address as it appears on the stock records of the
Corporation, with postage thereon prepaid.  Such notice shall state the place,
date and hour of the meeting, and, in the case of a special meeting, the purpose
or purposes for which the meeting is called.  If a meeting is adjourned to
another time or place, notice need not be given of the adjourned meeting if the
time and place thereof are announced at the meeting at which the adjournment is
taken and, at the adjourned meeting, such business may be transacted as might
properly have been transacted at the original meeting.  If the adjournment is
for more than 30 days, or if after the adjournment a new record date is fixed
for the adjourned meeting, a notice of the adjourned meeting shall be given to
each stockholder of record entitled to vote at such meeting.

     Notice of a Stockholders' meeting or adjournment thereof is waived upon the
occurrence of the following:

     (a)  A Stockholders' meeting is adjourned and a time and place for
readjournment is announced at the meeting at which the adjournment is taken, and
such date of readjournment is no more than 30 days from the date of adjournment;

     (b)  Receipt by the Corporation of a written notice of waiver, signed by
the person entitled to notice before or after the time stated therein;

     (c)  Attendance by the person entitled to notice and failure of such person
to object to the transaction of any business because the meeting is not lawfully
called or convened.

     Wherever notice is required to be given under any statute or the
Certificate of Incorporation or these Bylaws to any Stockholder to whom (a)
notice of two consecutive annual meetings, and all notices of meetings or of the
taking of action by written consent without a meeting to such person during the
period between such two consecutive annual meetings or (b) all, and at least
two, payments (if sent by first class mail) of dividends or interest on
securities during a twelve month period, have been mailed addressed to such
person at his address as shown on the records of the Corporation and have been
returned because undeliverable, the giving of notice to such person shall not be
required.  Any action or meeting which shall be taken or held without notice to
such person shall have the same force and effect as if such notice had been duly
given.  If any such person shall deliver to the Corporation a written notice
setting forth his then current address, the requirement that notice be given to
such person shall be reinstated.  In the event that the action taken by the
Corporation is such as to require the filing of a certificate under 


                                          2
<PAGE>

any of the other sections of the General Corporation Law, the certificate need
not state that notice was not given to persons to whom notice was not required
to be given pursuant to this Section 4.

     Section 5.     QUORUM.  On all questions, the presence of the holders of a
majority of the shares entitled to vote, in person or by proxy, shall constitute
a quorum for the transaction of business at any meeting of the Stockholders.  On
all questions, the Stockholders present at a duly called or held meeting at
which a quorum is present may continue to do business until adjournment,
notwithstanding the withdrawal of enough Stockholders to leave less than a
quorum, if any action taken (other than adjournment) is approved by at least a
majority of the shares required to constitute a quorum.

     Section 6.     ADJOURNED MEETING.  Any Stockholders' meeting, annual or
special, whether or not a quorum is present, may be adjourned by vote of a
majority of the shares present, either in person or by proxy, but in the absence
of a quorum no other business may be transacted at such meeting, except as
expressly provided in Section 5 of this Article.

     Section 7.     VOTING.

     (a)  The Stockholders entitled to notice of any meeting or to vote at such
meeting shall only be persons whose names stand on the stock records of the
Corporation on the record date determined in accordance with the provisions of
Section 12 of this Article, provided, however, that if no such record date shall
be fixed by the Board, only persons in whose names shares stand on the stock
records of the corporation at the close of business on the business day next
preceding the day on which notice of the meeting is given or if such notice is
waived, at the close of business on the business day next preceding the day on
which the meeting of Stockholders is held, shall be entitled to vote at such
meeting, and such day shall be the record date for such meeting.

     (b)  Voting shall in all cases be subject to the provisions of Sections 217
and 128 of the General Corporation Law (relating to voting of shares held by
fiduciaries or pledgors, held in joint ownership, and voting of shares by voting
trusts or in accordance with other voting agreements).

     (c)  At each meeting of the Stockholders of the Corporation, holders of a
majority of the voting power of the Corporation entitled to vote thereat,
present either in person or by proxy, shall constitute a quorum for the
transaction of business.  In the absence of quorum, the Stockholders of the
Corporation present in person or by proxy and entitled to vote at the meeting
may, by majority vote, or, in the absence of all Stockholders, any officer
entitled to preside or act as Secretary at such meeting, shall have the power to
adjourn the meeting from time to time until Stockholders holding the requisite
amount of stock shall be present in person or by proxy.  At any 


                                          3
<PAGE>

such adjourned meeting at which a quorum may be present, any business may be
transacted which might have been transacted at the meeting as originally called.

     (d)  On all questions, each Stockholder of the Corporation entitled to vote
on such questions shall be entitled to vote in person or by proxy one vote for
each share of Common Stock of the Corporation held by such Stockholder.  Unless
otherwise provided in the Certificate of Incorporation or by statute, the
affirmative vote of a majority of the shares represented and voting at a duly
held meeting at which a quorum is present shall be the act of the Stockholders. 
Unless demanded by a Stockholder present in person or by proxy at any meeting
and entitled to vote thereat, the vote on any question need not be by ballot. 
Upon demand for a vote by ballot upon any question by any Stockholder present in
person or by proxy at any meeting and entitled to vote thereat, such vote shall
be taken by ballot.  On any vote taken by ballot, each ballot shall be signed by
the Stockholder voting, or by his lawful proxy, and shall state the number and
kind of shares voted.

     Section 8.     PROXIES.  Each Stockholder entitled to vote at a meeting of
Stockholders may authorize another person or persons to act for him by proxy,
but no such proxy shall be voted or acted upon after three years from its date,
unless the proxy provides for a longer period.  Any such proxy shall be
delivered to the secretary of such meeting, at or prior to the time designated
in the order of business for so delivering such proxies.  A duly elected proxy
shall be irrevocable if it states that it is irrevocable and if, and only so
long as, it is coupled with an interest sufficient in law to support an
irrevocable power.  A proxy may be made irrevocable regardless of whether the
interest with which it is coupled is an interest in the stock itself or and
interest in the Corporation generally.

     Section 9.     STOCKHOLDER LIST.  The officer who has charge of the stock
ledger of the Corporation shall prepare and make, at least ten days before every
meeting of Stockholders, a complete list of the Stockholders entitled to vote at
the meeting, arranged in alphabetical order, and showing the address of each
Stockholder and the number of shares registered in the name of each Stockholder.
Such list shall be open to the examination of any Stockholder, for any purposes
germane to the meeting, during ordinary business hours, for a period of at least
ten days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held. 
The list shall also be produced and kept at the time and place of the meeting
during the whole time thereof, and may be inspected by an Stockholder who is
present.

     Section 10.    INSPECTORS OF ELECTION.  In advance of any meeting of the
Stockholders, the Board shall appoint at least one person, other than nominees
for office, as inspector of election to act at such meeting or any adjournment
thereof.  The number of such inspectors of election shall be one or three.  In
case any person appointed as inspector fails to appear or refuses to act, the
vacancy shall be filled by appointment by the Board in advance of the meeting,
or at the 


                                          4
<PAGE>

meeting by the chairman of the meeting.  If there are three inspectors of
election, the decision, act or certificate of a majority is effective in all
respects as the decision, act or certificate of all.

     The duties of each such inspector of election shall include:

     (a)  determining the number of shares outstanding and the voting power of
each;

     (b)  determining the shares represented at the meeting;

     (c)  determining the existence of a quorum;

     (d)  determining the authenticity, validity and effect of proxies;

     (e)  receiving votes, ballots or consents;

     (f)  hearing and determining all challenges and questions in any way
arising in connection with the right to vote;

     (g)  retaining for a reasonable period the disposition of any challenges
made to the inspector's determinations;

     (h)  counting and tabulating all votes;

     (i)  determining when the polls shall close;

     (j)  determining the result of any election;

     (k)  certifying the determination of the number of shares represented at
the meeting, and the count of all votes and ballots;

     (l)  certifying any information considered in determining the validity and
counting of proxies and ballots if that information is used for the purpose of
reconciling proxies and ballots submitted by or on behalf of banks, brokers,
their nominees or similar persons which represent more votes than the
Stockholder holds of record; and

     (m)  performing such acts as may be proper to conduct the election or vote
with fairness to all Stockholders.

     Section 11.    RECORD DATE.  In order that the Corporation may determine
the Stockholders entitled to notice of or to vote at any meeting of Stockholders
or any adjournment thereof, or entitled to receive payment of any dividend or
other distribution or allotment of any rights, or 


                                          5
<PAGE>

entitled to exercise any rights in respect of any change, conversion or exchange
of stock or for the purpose of any other lawful action, the Board may fix, in
advance, a record date, which shall not be more than sixty nor less than ten
days before the date of such meeting, nor more than sixty days prior to any
other action.

     If no record date is fixed:

     (a)  The record date for determining Stockholders entitled to notice of or
to vote at a meeting of Stockholders shall be at the close of business on the
day next preceding the day on which notice is given, if notice is waived, at the
close of business on the day next preceding the day on which the meeting is
held;

     (b)  The record date for determining Stockholders for any other purpose
shall be at the close of business on the day on which the Board adopts the
resolution relating thereto.

     A determination of Stockholders of record entitled to notice of or to vote
at a meeting of Stockholders shall apply to any adjournment of the meeting;
provided, however, that the Board may fix a new record date for the adjourned
meeting.

     Section 12.    PROCEDURES FOR MEETINGS.  All meetings of Stockholders shall
be conducted according to such rules and procedures as the Board of Directors
may establish by resolution or, absent such a resolution, which the person
presiding over the meeting shall determine from time to time as being in the
best interests of the Stockholders and as may be deemed appropriate for insuring
that such meetings are conducted in a fair and orderly manner and in accordance
with the Certificate of Incorporation and these Bylaws.

     Section 13.    OPENING AND CLOSING OF POLLS.  An announcement shall be made
at each meeting of the Stockholders by the Chairman of the meeting of the date
and time of the opening and closing of polls for each matter upon which the
Stockholders will vote at the meeting.  No ballots, proxies or votes, nor any
revocations thereof or changes thereto, shall be accepted by the inspectors of
election after the closing of the polls unless the Delaware Court of Chancery
upon application by a Stockholder shall determine otherwise.


                                     ARTICLE III
                                  BOARD OF DIRECTORS


     Section 1.     POWERS.  The business and affairs of the Corporation shall
be managed by, or under the direction of the Board, except as may be otherwise
provided by the General Corporation Law or in the Certificate of Incorporation
or these Bylaws.  Without prejudice to 


                                          6
<PAGE>

such powers, but subject to the same limitation, it is hereby expressly declared
that the directors shall have the following powers in addition to other powers
enumerated in these Bylaws:

     (a)  To select and remove all officers, agents and employees of the
Corporation; prescribe any powers and duties for them that are consistent with
law, with the Certificate of Incorporation, and with these Bylaws; fix their
compensation; and require from them security for faithful service;

     (b)  To conduct, manage and control the affairs and business of the
Corporation, and to make rules and regulations therefor consistent with law,
with the Certificate of Incorporation and with these Bylaws;

     (C)  To change the offices of the Corporation from one location to another;
to fix and locate from time to time one or more other offices of the Corporation
within or without the State of Delaware; to cause the Corporation to be
qualified to do business and to conduct business in any other state, territory,
dependency or country; and to designate any place within or without the State of
Delaware for the holding of any Stockholders' meeting or meetings, including
annual meetings;

     (d)  To adopt, make and use a corporate seal; to prescribe the forms and
certificates of stock; and to alter the form of the seal and certificates;

     (e)  To authorize the issuance of shares of stock of the Corporation from
time to time, upon such terms and for such consideration as may be lawful;

     (f)  To borrow money and incur indebtedness for the purposes of the
Corporation, and to cause to be executed and delivered therefor, in the
corporate name, promissory notes, bonds, debentures, deeds of trust, mortgages,
pledges, hypothecations, and other evidences of debt and securities therefor.

     Section 2.     NUMBER AND QUALIFICATIONS.  The number of directors of the
Corporation shall be as specified in the Certificate of Incorporation. 
Directors need not be Stockholders of the Corporation unless required by the
Certificate of Incorporation.

     Section 3.     ELECTION AND TERM OF OFFICE.  Members of the Board of
Directors shall hold office for the terms specified in the Certificate of
Incorporation and until their successors have been elected as provided in the

                                          7
<PAGE>

     (a)  Any vacancy on the Board of Directors however resulting, shall be
filled only by a majority of the directors then in office, although less than a
quorum, or by a sole remaining director, and not by the Stockholders.  Any
director elected to fill a vacancy shall hold office for a term that shall
coincide with the term of the class to which such director shall have been
elected.

     (b)  If at any time, by reason of death, resignation or other cause, the
Corporation should have no directors in office, then any officer or any
Stockholder or an executor, administrator, trustee or guardian of a Stockholder,
or other fiduciary entrusted with like responsibility of the person or estate of
a Stockholder, may call a special meeting of Stockholders in accordance with the
provisions of the Certificate of Incorporation and the Bylaws or may apply to
the Delaware Court of Chancery for a decree summarily ordering an election as
provided in Section 211 of the General Corporation Law.

     (c)  If, at the time of filling any vacancy or any newly created
directorship, the directors then in office shall constitute less than a majority
of the whole Board (as constituted immediately prior to any such increase), the
Delaware Court of Chancery may, upon application of any Stockholder or
Stockholders holding at least 10 percent of the total number of shares at the
time outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office as aforesaid,
which election shall be governed by Section 211 of the General Corporation Law.

     (d)  Any of all of the directors of the Corporation may be removed from
office at any time, for cause only, by the affirmative vote of the holders of
75% of the shares of the Corporation then entitled to vote generally in the
election of directors, considered for purposes of this Section 4(a) as one
class.

     (e)  Any director may resign effective upon giving written notice to the
Chairman of the Board, the President, the Secretary or the Board, unless the
notice specifies a later date for the effectiveness of such resignation.

     Section 5.     PLACE OF MEETING.  Unless otherwise provided in the
Certificate of Incorporation, or by unanimous written consent of all action
directors, meetings, both regular and special, of the Board shall be held at the
Corporation's principal executive offices or at such other place or places
within or without the State of Delaware, as the Board may from time to time
determine.

     Section 6.     REGULAR MEETINGS.  Immediately following each annual meeting
of the Stockholders of the Corporation the Board shall hold a regular meeting at
the same time at which 


                                          8
<PAGE>

such Stockholders' meeting is held, or any other place as may be fixed from time
to time by the Board of Directors.  Notice of such meeting need not be given.

     Other regular meetings of the Board shall be held without call at such time
and place as the Board may from time to time by resolution determine.  If any
day fixed for a regular meeting shall be a legal holiday at the place where the
meeting is to be held, then the meeting which would otherwise be held on that
day shall be held at the same hour on the next succeeding business day not a
legal holiday.  Notice of a regular meeting need not be given.

     Section 7.     SPECIAL MEETINGS.  Except as otherwise provided in the
Certificate of Incorporation, special meetings of the Board for any purpose or
purposes may be called at any time by the Chairman of the Board, the Chief
Executive Officer, the President, the Secretary or by any three directors.

     Written notice of the time and place of special meetings shall be delivered
personally to each director or communicated to each director by telephone,
telegraph, telex, facsimile transmission, courier service, cable or mail or
other form of recorded communication, charges prepaid, addressed to each
director at that director's address as it is shown on the records of the
Corporation or, if it is not so shown on such records or is not readily
ascertainable, at the director's residence or usual place of business.  In case
such notice is mailed, it shall be deposited in the United States mail at least
seven days prior to the time of the holding of the meeting.  In case such notice
is delivered personally or by other form of written communication, it shall be
delivered at least 48 hours before the time of the holding of the meeting.  The
notice shall state the time of the meeting, but need not specify the place of
the meeting if the meeting is to be held at the principal executive office of
the Corporation.  The notice need not state the purpose of the meeting unless
expressly provided otherwise by statute.

     Section 8.     MEETINGS BY COMMUNICATION EQUIPMENT.  Members of the Board
of the Corporation, or any committee designated by the Board, may participate in
a meeting of the Board or committee by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other.  Participation in a meeting pursuant to this
section shall constitute presence in person at such meeting.

     Section 9.     QUORUM AND MANNER OF ACTING.  The presence of a majority of
the total number of directors shall constitute a quorum for the transaction of
business, and the act of a majority of the directors present at a meeting duly
held shall be the act of the Board.  In the absence of a quorum, a majority of
the directors present may adjourn any meeting from time to time until a quorum
is present.  Notice of a adjourned meeting need not be given.

     Section 10.     VALIDATION OF DEFECTIVELY CALLED OR NOTICED MEETINGS.  The
transactions of any meeting of the Board, however called and noticed and
wherever held, shall be as valid as 


                                          9
<PAGE>

though made or performed at a meeting duly held after regular call and notice,
if, either before or after the meeting, each of the directors not present or
who, though present, has prior to the meeting or at its commencement protested
the lack of proper notice to such director, signs a written waiver of notice or
a consent to holding such meeting or approval of the minutes thereof.  All such

                         OFFICERS, EMPLOYEES AND OTHER AGENTS

     Section 1.     AGENTS, PROCEEDINGS AND EXPENSES.  for the purposes of this
Article, "agent" means any person who is or was a director, officer, employee or
other agent of the corporation, or is or was a director, officer, employee or
agent of corporation as a director, officer, employee or agent of another
foreign or domestic corporation, partnership, joint venture, trust or other
enterprise, or was a director, officer, employee or agent of a foreign or
domestic corporation which was a predecessor corporation of the corporation or
of another enterprise at the request of such predecessor corporation;
"proceeding" means any threatened, pending or complete action or proceeding,
whether civil, criminal, administrative, or investigative; and "expenses"
includes, without limitation, attorneys' fees and any expenses of establishing a
right to indemnification under Section 2 or Section 3 of this Article.

     Section 2.     ACTIONS OTHER THAN BY THE CORPORATION.  The Corporation
shall have power to indemnify any person who was or is a party or is threatened
to be made a party to any threatened, pending or completed action, suit or
proceeding, whether civil, criminal, administrative or investigative (other than
a action by or in the right of the Corporation) by reason of the fact that he is
or was a director, officer, employee or agent of the Corporation, or is or was
serving at the request of the Corporation as a director, officer, employee or
agent of another corporation, partnership, joint venture, trust or other
enterprise, against expenses (including attorneys' fees), judgments, fines and
amounts paid in settlement actually and reasonably incurred by him in connection
with such action, suit or proceeding if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interest of the
Corporation, and with respect to any criminal action or proceeding, had no
reasonable cause to believe his conduct was unlawful.  The termination of any
action, suit or proceeding by judgment, order, settlement, conviction, or upon a
plea of nolo contendere or its equivalent, shall not, of itself, create a
presumption that the person did not act in good faith and in a manner which he
reasonably believed to be in or not opposed to the best interests of the
Corporation, and, with respect to any criminal action or proceeding, had
reasonable cause to believe that his conduct was unlawful.

     Section 3.     ACTIONS BY THE CORPORATION.  The Corporation shall have
power to indemnify any person who was or is a party or is threatened to be made
a party to any threatened, 


                                          13
<PAGE>

pending or completed action or suit by or in the right of the Corporation to
procure a judgment in its favor by reason of the fact that he is or was a
director, officer, employee or agent of the Corporation, or is or was serving at
the request of the Corporation as a director, officer, employee or agent of
another corporation, partnership, joint venture, trust or other enterprise
against expenses (including attorneys' fees) actually and reasonably incurred by
him in connection with the defense or settlement of such action or suit if he
acted in good faith and in a manner he reasonably believed to be in or not
opposed to the best interests of the Corporation and except that no
indemnification shall be made in respect of any claim, issue or matter as to
which such person shall have been adjudged to be liable for negligence or
misconduct in the performance of his duty to the Corporation unless and only to
the extent that the Court of Chancery or the court in which such action or suit
was brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is
fairly and reasonably entitled to indemnity for such expenses which the Court of
Chancery or such other court shall deem proper.

     Section 4.     SUCCESSFUL DEFENSE BY AGENT.  To the extent that a director,
officer, employee or agent of the Corporation has been successful on the merits
or otherwise in defense of any action, suit or proceeding referred to in
Sections 2 and 3, or in defense of any claim, issue or matter therein, he shall
be indemnified against expenses (including attorneys' fees) actually and
reasonably incurred by him in connection therewith.

     Section 5.     REQUIRED APPROVAL.  Any indemnification under Sections 1 and
2 (unless ordered by a court) shall be made by the Corporation only as
authorized in the specific case upon a determination that indemnification of the
director, officer, employee or agent is proper in the circumstances because he
has met the applicable standard of conduct set forth in Sections 2 and 3.  Such
determination shall be made (a) by the Board by a majority vote of quorum
consisting of directors who were not parties to such actions, suit or
proceedings, or (b) if such disinterested directors so direct, by independent
legal counsel in a written opinion, or (c) by the affirmative vote of a majority
of Stockholders.

     Section 6.     ADVANCE OF EXPENSES.  Expenses incurred in defending a civil
or criminal action, suit or proceeding may be paid by the Corporation in advance
of the final disposition of such action, suit or proceeding as authorized by the
Board in the specific case upon receipt of an undertaking by or on behalf of the
director, officer, employee or agent to repay such amount unless it shall
ultimately be determined that he is entitled to be indemnified by the
Corporation as authorized in this Article.  Such expenses incurred by other
employees and agents, may be so paid upon such terms and conditions, if any, as
the Board deems appropriate.

     Section 7.     CONTRACTUAL RIGHTS.  The indemnification provided by this
Article shall not be deemed exclusive of any other rights to which those seeking
indemnification may be entitled under any agreement, vote of Stockholders or
disinterested directors or otherwise, both as to 


                                          14
<PAGE>

action in his official capacity and as to action in another capacity while
holding such office, and shall continue as to a person who has ceased to be a
director, officer, employee or agent and shall inure to the benefit of the
heirs, executors and administrators of such a person.

     Section 8.     LIMITATIONS.  No indemnification or advance shall be made
under this Article, except as provided in Section 4, in any circumstances where
it appears:

     (a)  That it would be inconsistent with a provision of the Certificate of
Incorporation, a resolution of the Stockholders or an agreement in effect at the
time of accrual of the alleged cause of action asserted in the proceeding in
which the expenses were incurred or other amounts were paid, which prohibits or
otherwise limits indemnification;

     (b)  That it would be inconsistent with any condition expressly imposed by
a court in approving a settlement.

     Section 9.     INSURANCE.  The Corporation shall have the power to purchase
and maintain insurance on behalf of any person who is or was director, officer,
employee or agent of the Corporation, or is or was serving at the request of the
Corporation as a director, officer, employee or agent of another corporation,
partnership, joint venture, trust or other enterprise against any liability
asserted against him and incurred by him in any such capacity or arising out of
his status as such, whether or not the Corporation would have the power to
indemnify him against such liability under the provisions of this Article.

     Section 10.    CONSTITUENT CORPORATIONS.  For purposes of this Article,
references to "the Corporation" shall include, in addition to the Corporation,
any constituent corporation (including any constituent of a constituent)
absorbed in a consolidation or merger which, if its separate existence had
continued, would have had power and authority to indemnify its directors,
officers, employees or agents of such constituent corporation, or is or was
serving at the request of such constituent corporation as a director, officer,
employee or agent of another corporation, partnership, joint venture, trust or
other enterprise, shall stand in the same position under the provisions of this
Article with respect to the resulting or surviving corporation as he would have
with respect to such constituent corporation if its separate existence had
continued.

     Section 11.    DEFINITIONS.  For purposes of this Article, references to
"other enterprises" shall include employee benefit plans; references to "fines"
shall include any excise taxes assessed on a person with respect to an employee
benefit plan; and references to "serving at the request of the Corporation"
shall include any service as a director, officer, employee or agent of the
Corporation which imposes duties on, or involves services by, such director,
officer, employee, or agent with respect to an employee benefit plan, its
participants, or beneficiaries; and an person who acted in good faith and in a
manner he reasonably believed to be in the interests of the 


                                          15
<PAGE>

participants and beneficiaries of an employee benefit plan shall be deemed to
have acted in a manner "not opposed to that best interest of the Corporation" as
referred to in this Article.

stock ledger, a list of Stockholders, and its other books and records, and to

     SECTION 3.     FORM AND EXECUTION OF WARRANT CERTIFICATES.

     (a)  The Warrant Certificates shall be substantially in the form annexed 
hereto as Exhibit A (the provisions of which are hereby incorporated herein) 
and may have such letters, numbers or other marks of identification or 
designation and such legends, summaries or endorsements printed, lithographed 
or engraved thereon as the Company may deem appropriate and as are not 
inconsistent with the provisions of this Agreement, or as may be required to 
comply with any law or with any rule or regulation made pursuant thereto or 
with any rule or regulation of any stock exchange on which the Warrants may 
be listed, or to conform to usage.  The Warrant Certificates shall be dated 
the date of issuance thereof (whether upon initial issuance, transfer, 
exchange or in lieu of mutilated, lost, stolen or destroyed Warrant 
Certificates) and issued in registered form. Warrants shall be numbered 
serially with the letter W on the Warrants. 

     (b)  Warrant Certificates shall be executed on behalf of the Company by

Warrant Certificates, nevertheless, may be countersigned by the Warrant 
Agent, issued and delivered with the same force and effect as though the 
person who signed such Warrant Certificates had not ceased to be such officer 
of the Company.  After countersignature by the Warrant Agent, Warrant 
Certificates shall be delivered by the Warrant Agent to the Registered Holder 
promptly and without further action by the Company, except as otherwise 
provided by Section 4(a) hereof. 

                                       4

     SECTION 4.  EXERCISE.

     (a)  Warrants in denominations of one or whole number multiples thereof 
may be exercised by the Registered Holder thereof commencing at any time on 
or after the Initial Warrant Exercise Date, but not after the Warrant 
Expiration Date, upon the terms and subject to the conditions set forth 
herein and in the applicable Warrant Certificate.  A Warrant shall be deemed 
to have been exercised immediately prior to the close of business on the 
Exercise Date and the person entitled to receive the securities deliverable 
upon such exercise shall be treated for all purposes as the holder, upon 
exercise thereof, as of the close of business on the Exercise Date.  If 
Warrants in denominations other than whole number multiples thereof shall be 
exercised at one time by the same Registered Holder, the number of full 
shares of Common Stock which shall be issuable upon exercise thereof shall be 
computed on the basis of the aggregate number of full shares of Common Stock 
issuable upon such exercise.  As soon as practicable on or after the Exercise 
Date and in any event within five business days after such date, if one or 
more Warrants have been exercised, the Warrant Agent on behalf of the Company 
shall cause to be issued to the person or persons entitled to receive the 
same a Common Stock certificate or certificates for the shares of Common 
Stock deliverable upon such exercise, and the Warrant Agent shall deliver the 
same to the person or persons entitled thereto.  Upon the exercise of any one 
or more Warrants, the Warrant Agent shall promptly notify the Company in 
writing of such fact and of the number of securities deliverable upon such 
exercise and shall cause the payment of an amount in cash or by check made 
payable to the order of the Company, equal to the Purchase Price for such 
securities, to be deposited promptly in the Company's designated bank 
account. 

     (b)  The Company shall not be required to issue fractional shares on the 
exercise of Warrants.  Warrants may only be exercised in such multiples as 
are required to permit the issuance by the Company of one or more whole 
shares.  If one or more Warrants shall be presented for exercise in full at 
the same time by the same Registered Holder, the number of whole shares which 
shall be issuable upon such exercise thereof shall be computed on the basis 
of the aggregate number of shares purchasable on exercise of the Warrants so 
presented.  If any fraction of a share would, except for the provisions 
provided herein, be issuable on the exercise of any Warrant (or specified 
portion thereof), the Company shall pay an amount in cash equal to such 
fraction multiplied by the then current market value of a share of Common 
Stock, determined as follows: 

          (1)  If the Common Stock is listed, or admitted to unlisted trading 
privileges, on a national securities exchange, or is traded on Nasdaq, the 
current market value of a share of Common Stock shall be the closing sale 
price of the Common Stock at the end of the regular trading session on the 
last business day prior to the date of exercise of the Warrants on whichever 
of such exchanges or Nasdaq had the highest average daily trading volume for 
the Common Stock on such day; or 

          (2)  If the Common Stock is not listed or admitted to unlisted 
trading privileges on any national securities exchange, or listed, quoted or 
reported for trading on Nasdaq, but is traded in the over-the-counter market, 
the current market value of a share of Common Stock shall be the average of 
the last reported bid and asked prices of the Common Stock reported by the 
National

                                       5

<PAGE>

Quotation Bureau, Inc. on the OTC Electronic Bulletin Board operated by 
Nasdaq on the last business day prior to the date of exercise of the 
Warrants; or 

          (3)  If the Common Stock is not listed, admitted to unlisted 
trading privileges on any national securities exchange, or listed, quoted or 
reported for trading on Nasdaq, and bid and asked prices of the Common Stock 
are not reported by the National Quotation Bureau, Inc. on the OTC Electronic 
Bulletin Board operated by Nasdaq, the current market value of a share of 
Common Stock shall be an amount, not less than the book value thereof as of 
the end of the most recently completed fiscal quarter of the Company ending 
prior to the date of exercise, determined by the members of the Board of 
Directors of the Company exercising good faith and using customary valuation 
methods.

     SECTION 5.  RESERVATION OF SHARES; LISTING; PAYMENT OF TAXES; ETC.

     (a)  The Company covenants that it will at all times reserve and keep 
available out of its authorized Common Stock, solely for the purpose of issue 
upon exercise of Warrants, such number of shares of Common Stock as shall 
then be issuable upon the exercise of all outstanding Warrants.  The Company 
covenants that all shares of Common Stock which shall be issuable upon 
exercise of the Warrants shall, at the time of issuance and delivery thereof 
in accordance with the terms hereof and of the Warrant Certificates, be duly 
and validly issued and fully paid and nonassessable and free from all 
preemptive or similar rights, taxes, liens and charges with respect to the 
issue thereof, and that upon issuance such shares shall be listed on each 
securities exchange, if any, on which the other shares of outstanding Common 
Stock of the Company are then listed.  

     (b)  The Company covenants that if any securities to be reserved for the 
purpose of exercise of Warrants hereunder require registration with, or 
approval of, any governmental authority under any federal securities law 
before such securities may be validly issued or delivered upon such exercise, 
then the Company will file a registration statement under the federal 
securities laws or a post-effective amendment to a then effective 
registration statement, use its reasonable best efforts to cause such filed 
registration statement to become effective and to keep any such effective  
registration statement current while any of the Warrants are outstanding, and 
deliver a prospectus which complies with Section 10(a)(3) of the Act to the 
Registered Holder exercising the Warrant (except, if in the opinion of 
counsel to the Company, such registration is not required under the federal 
securities law or if the Company receives a letter from the staff of the 
Commission stating that it would not take any enforcement action if such 
registration is not effected).  The Company will use its reasonable best 
efforts to obtain appropriate approvals or registrations under state "blue 
sky" securities laws with respect to any such securities.  However, Warrants 
may not be exercised by, or shares of Common Stock issued to, any Registered 
Holder in any state in which such exercise would be unlawful.

     (c)  The Company shall indemnify the Representative and each person, if 
any, who controls the Representative within the meaning of Section 15 of the 
Act or Section 20(a) of the Exchange Act against all loss, claim, damage, 
expense or liability (including all expenses reasonably incurred in 
investigating, preparing or defending against any claim whatsoever) to which 
any of them may become subject under the Act, the Exchange Act or otherwise, 
arising from the registration statement or prospectus referred to in Section 
5(b) hereof to the same extent and with the same effect (including

                                       6

<PAGE>

the provisions regarding contribution) as the provisions pursuant to which 
the Company has agreed to indemnify the Representative contained in Section 7 
of the Underwriting Agreement. 

     (d)  The Company shall pay all documentary, stamp or similar taxes and 
other governmental charges that may be imposed with respect to the issuance 
of Warrants, or the issuance or delivery of any shares of Common Stock upon 
exercise of the Warrants; provided, however, that if shares of Common Stock 
are to be delivered in a name other than the name of the Registered Holder of 
the Warrant Certificate representing any Warrant being exercised, then no 
such delivery shall be made unless the person requesting the same has paid to 
the Warrant Agent the amount of transfer taxes or charges incident thereto, 
if any. 

     (e)  The Warrant Agent is hereby irrevocably authorized as the Transfer 
Agent to (i) register the transfer of Warrant Certificates and (ii) 
requisition from time to time certificates representing shares of Common 
Stock or other securities required upon exercise of the Warrants, and the 
Company will comply with all such requisitions. 

     SECTION 6.  EXCHANGE AND REGISTRATION OF TRANSFER.

     (a)  Warrant Certificates may be exchanged for other Warrant 
Certificates representing an equal aggregate number of Warrants or may be 
transferred in whole or in part.  Warrant Certificates to be exchanged shall 
be surrendered to the Warrant Agent at the Corporate Office, and, upon 
satisfaction of the terms and provisions hereof, the Company shall execute 
and the Warrant Agent shall countersign, issue and deliver in exchange 
therefor the Warrant Certificate or Certificates which the Registered Holder 
making the exchange shall be entitled to receive.

     (b)  The Warrant Agent shall keep, at the Corporate Office, books in 
which, subject to such reasonable regulations as it may prescribe, it shall 
register Warrant Certificates and the transfer thereof in accordance with 
customary practice.  Upon due presentment for registration of transfer of any 
Warrant Certificate at such office, the Company shall execute and the Warrant 
Agent shall countersign and issue and deliver to the transferee or 
transferees a new Warrant Certificate or Certificates representing an equal 
aggregate number of Warrants.

     (c)  With respect to all Warrant Certificates presented for registration 
of transfer, or for exchange or exercise, the subscription or exercise form, 
as the case may be, on the reverse thereof shall be duly endorsed or be 
accompanied by a written instrument or instruments of transfer and 
subscription, in form satisfactory to the Company and the Warrant Agent, duly 
executed by the Registered Holder thereof or his attorney-in-fact duly 
authorized in writing. 

     (d)  A service charge may be imposed by the Warrant Agent and charged to 
the Registered Holder for any exchange or registration of transfer of Warrant 
Certificates.  In addition, the Company may require payment by such Holder of 
a sum sufficient to cover any tax or other governmental charge that may be 
imposed in connection therewith. 

     (e)  All Warrant Certificates surrendered for exercise or for exchange 
in case of mutilated Warrant Certificates shall be promptly canceled by the 
Warrant Agent and thereafter retained by the Warrant Agent until termination 
of this Agreement. 

                                       7

<PAGE>

     (f)  Prior to due presentment for registration of transfer thereof, the 
Company and the Warrant Agent may deem and treat the Registered Holder of any 
Warrant Certificate as the absolute owner thereof and of each Warrant 
represented thereby (notwithstanding any notations of ownership or writing 
thereon made by anyone other than a duly authorized officer of the Company or 
the Warrant Agent) for all purposes and shall not be affected by any notice 
to the contrary. 

     SECTION 7.  LOSS OR MUTILATION.

     Upon receipt by the Company and the Warrant Agent of evidence 
satisfactory to them of the ownership of and the loss, theft, destruction or 
mutilation of any Warrant Certificate and (in the case of loss, theft or 
destruction) of indemnity satisfactory to them, and (in case of mutilation) 
upon surrender and cancellation thereof, the Company shall execute and the 
Warrant Agent shall (in the absence of notice to the Company and/or the 
Warrant Agent that a new Warrant Certificate has been acquired by a bona fide 
purchaser) countersign and deliver to the Registered Holder in lieu thereof a 
new Warrant Certificate of like tenor representing an equal aggregate number 
of Warrants.  Applicants for a substitute Warrant Certificate shall also 
comply with such other reasonable regulations and pay such other reasonable 
charges as the Warrant Agent may prescribe.

     SECTION 8.   ADJUSTMENT OF PURCHASE PRICE AND NUMBER OF SHARES OF COMMON
                  STOCK DELIVERABLE.

     (a)  Except as hereinafter provided, in the event the Company shall, at 
any time or from time to time after the date hereof and prior to the Warrant 
Expiration Date, issue or sell any shares of Common Stock for a consideration 
per share less than the Purchase Price or issue any shares of Common Stock as 
a stock dividend to the holders of Common Stock, or subdivide or combine the 
outstanding shares of Common Stock into a greater or lesser number of shares 
(any such issuance, subdivision or combination being herein called a "Change 
of Shares"), then, and thereafter upon each further Change of Shares, the 
Purchase Price for the Warrants (whether or not the same shall be issued and 
outstanding) in effect immediately prior to such Change of Shares shall be 
changed to a price (including any applicable fraction of a cent to the 
nearest cent) determined by dividing (i) the sum of (a) the total number of 
shares of Common Stock outstanding immediately prior to such Change of 
Shares, multiplied by the Purchase Price in effect immediately prior to such 
Change of Shares and (b) the consideration, if any, received by the Company 
upon such sale, issuance, subdivision or combination, by (ii) the total 
number of shares of Common Stock outstanding immediately after such Change of 
Shares; provided, however, that in no event shall the Purchase Price be 
adjusted pursuant to this computation to an amount in excess of the Purchase 
Price in effect immediately prior to such computation, except in the case of 
a combination of outstanding shares of Common Stock. 

     For the purposes of any adjustment to be made in accordance with this 
Section 8(a), the following provisions shall be applicable:

     (A)  In case of the issuance or sale of shares of Common Stock (or of 
other securities deemed hereunder to involve the issuance or sale of shares 
of Common Stock) for a consideration part or all of which shall be cash, the 
amount of the cash portion of the consideration therefor deemed to have been 
received by the Company shall be (i) the subscription price, if shares of 
Common Stock

                                       8

<PAGE>

are offered by the Company for subscription, or (ii) the gross public 
offering price (before deducting therefrom any compensation paid or discount 
allowed in the sale, underwriting or purchase thereof by underwriters or 
dealers or others performing similar services, or any expenses incurred in 
connection therewith), if such securities are sold to underwriters or dealers 
for public offering without a subscription offering, or (iii) the gross 
amount of cash actually received by the Company for such securities, in any 
other case. 

     (B)  In case of the issuance or sale (otherwise than as a dividend or 
other distribution on any stock of the Company, and otherwise than on the 
exercise of options, rights or warrants or the conversion or exchange of 
convertible or exchangeable securities) of shares of Common Stock (or of 
other securities deemed hereunder to involve the issuance or sale of shares 
of Common Stock) for a consideration part or all of which shall be other than 
cash, the amount of the consideration therefor other than cash deemed to have 
been received by the Company shall be the value of such consideration as 
determined in good faith by the Board of Directors of the Company, using 
customary valuation methods and on the basis of prevailing market values for 
similar property or services. 

     (C)  Shares of Common Stock issuable by way of dividend or other 
distribution on any stock of the Company shall be deemed to have been issued 
immediately after the opening of business on the day following the record 
date for the determination of shareholders entitled to receive such dividend 
or other distribution and shall be deemed to have been issued without 
consideration. 

     (D)  The reclassification of securities of the Company other than shares 
of Common Stock into securities including shares of Common Stock shall be 
deemed to involve the issuance of such shares of Common Stock for a 
consideration other than cash immediately prior to the close of business on 
the date fixed for the determination of security holders entitled to receive 
such shares, and the value of the consideration allocable to such shares of 
Common Stock shall be determined as provided in subsection (B) of this 
Section 8(a). 

     (E)  The number of shares of Common Stock at any one time outstanding 
shall be deemed to include the aggregate maximum number of shares issuable 
(subject to readjustment upon the actual issuance thereof) upon the exercise 
of options, rights or warrants and upon the conversion or exchange of 
convertible or exchangeable securities. 

     (b)  Upon each adjustment of the Purchase Price pursuant to this Section 
8, the number of shares of Common Stock purchasable upon the exercise of each 
Warrant shall be the number derived by multiplying the number of shares of 
Common Stock purchasable immediately prior to such adjustment by the Purchase 
Price in effect prior to such adjustment and dividing the product so obtained 
by the applicable adjusted Purchase Price. 

     (c)  In case the Company shall at any time after the date hereof issue 
options, rights or warrants to subscribe for shares of Common Stock, or issue 
any securities convertible into or exchangeable for shares of Common Stock, 
for a consideration per share (determined as provided in Sections 8(a) and 
8(b) and as provided below) less than the Purchase Price in effect 
immediately prior to the issuance of such options, rights or warrants, or 
such convertible or exchangeable securities, or without consideration 
(including the issuance of any such securities by way of dividend or other 
distribution), the Purchase Price for the Warrants (whether or not the same 
shall be issued and

                                       9

<PAGE>

outstanding) in effect immediately prior to the issuance of such options, 
rights or warrants, or such convertible or exchangeable securities, as the 
case may be, and the number of shares of Common Stock purchasable upon the 
exercise of such Warrants, shall be reduced to a price determined by making 
the computation in accordance with the provisions of Sections 8(a) and 8(b) 
hereof, provided that: 

          (A)  The aggregate maximum number of shares of Common Stock 
issuable or that may become issuable under such options, rights or warrants 
(assuming exercise in full even if not then currently exercisable or 
currently exercisable in full) shall be deemed to be issued and outstanding 
at the time such options, rights or warrants were issued, for a consideration 
equal to the minimum exercise price per share provided for in such options, 
rights or warrants at the time of issuance, plus the consideration, if any, 
received by the Company for the grant of such options, rights or warrants; 
provided, however, that upon the expiration or other termination of such 
options, rights or warrants, if any thereof shall not have been exercised, 
the number of shares of Common Stock deemed to be issued and outstanding 
pursuant to this subsection (A) (and for the purposes of subsection (E) of 
Section 8(a) hereof) shall be reduced by the number of shares as to which 
options, warrants and/or rights shall have expired, and such number of shares 
shall no longer be deemed to be issued and outstanding, and the Purchase 
Price then in effect shall forthwith be readjusted and thereafter be the 
price that it would have been had adjustment been made on the basis of the 
issuance only of the shares actually issued plus the shares remaining 
issuable upon the exercise of those options, rights or warrants as to which 
the exercise rights shall not have expired or terminated unexercised. 

          (B)  The aggregate maximum number of shares of Common Stock 
issuable or that may become issuable upon conversion or exchange of any 
convertible or exchangeable securities (assuming conversion or exchange in 
full even if not then currently convertible or exchangeable in full) shall be 
deemed to be issued and outstanding at the time of issuance of such 
securities, for a consideration equal to the consideration received by the 
Company for such securities, plus the minimum consideration, if any, 
receivable by the Company upon the conversion or exchange thereof; provided, 
however, that upon the termination of the right to convert or exchange such 
convertible or exchangeable securities (whether by reason of redemption or 
otherwise), the number of shares of Common Stock deemed to be issued and 
outstanding pursuant to this subsection (B) (and for the purposes of 
subsection (E) of Section 8(a) hereof) shall be reduced by the number of 
shares as to which the conversion or exchange rights shall have expired or 
terminated unexercised, and such number of shares shall no longer be deemed 
to be  issued and outstanding, and the Purchase Price then in effect shall 
forthwith be readjusted and thereafter be the price that it would have been 
had adjustment been made on the basis of the issuance only of the shares 
actually issued plus the shares remaining issuable upon conversion or 
exchange of those convertible or exchangeable securities as to which the 
conversion or exchange rights shall not have expired or terminated 
unexercised. 

          (C)  If any change shall occur in the price per share provided for 
in any of the options, rights or warrants referred to in subsection (A) of 
this Section 8(c), or in the price per share or ratio at which the securities 
referred to in subsection (B) of this Section 8(c) are convertible or 
exchangeable, such options, rights or warrants or conversion or exchange 
rights, as the case may be, to the extent not theretofore exercised, shall be 
deemed to have expired or terminated on the date when such price change 
became effective in respect of shares not theretofore issued pursuant to the

                                       10

<PAGE>

exercise or conversion or exchange thereof, and the Company shall be deemed 
to have issued upon such date new options, rights or warrants or convertible 
or exchangeable securities. 

     (d)  In case of any reclassification or change of outstanding shares of 
Common Stock issuable upon exercise of the Warrants (other than a change in 
par value, or from par value to no par value, or from no par value to par 
value or as a result of a subdivision or combination), or in case of any 
consolidation or merger of the Company with or into another corporation 
(other than a merger with a subsidiary of the Company in which merger the 
Company is the continuing corporation) and which does not result in any 
reclassification or change of the then outstanding shares of Common Stock or 
other capital stock issuable upon exercise of the Warrants (other than a 
change in par value, or from par value to no par value, or from no par value 
to par value or as a result of subdivision or combination) or in case of any 
sale or  conveyance to another corporation of the property of the Company as 
an entirety or substantially as an entirety, then, as a condition of such 
reclassification, change, consolidation, merger, sale or conveyance, the 
Company, or such successor or purchasing corporation, as the case may be, 
shall make lawful and adequate provision whereby the Registered Holder of 
each Warrant then outstanding shall have the right thereafter to receive on 
exercise of such Warrant the kind and amount of securities and property 
receivable upon such reclassification, change, consolidation, merger, sale or 
conveyance by a holder of the number of securities issuable upon exercise of 
such Warrant immediately prior to such reclassification, change, 
consolidation, merger, sale or conveyance and shall forthwith file at the 
Corporate Office a statement signed by its Chief Executive Officer, President 
or a Vice President and by its Chief Financial Officer or an Assistant Chief 
Financial Officer or its Secretary or an Assistant Secretary evidencing such 
provision.  Such provisions shall include provision for adjustments which 
shall be as nearly equivalent as may be practicable to the adjustments 
provided for in Sections 8(a), (b) and (c).  The above provisions of this 
Section 8(d) shall similarly apply to successive reclassifications and 
changes of shares of Common Stock and to successive consolidations, mergers, 
sales or conveyances. 

     (e)  Irrespective of any adjustments or changes in the Purchase Price or 
the number of shares of Common Stock purchasable upon exercise of the 
Warrants, the Warrant Certificates theretofore and thereafter issued shall, 
unless the Company shall exercise its option to issue new Warrant 
Certificates pursuant to Section 2(d) hereof, continue to express the 
Purchase Price per share and the number of shares purchasable thereunder as 
the Purchase Price per share and the number of shares purchasable thereunder 
were expressed in the Warrant Certificates when the same were originally 
issued. 

     (f)  After each adjustment of the Purchase Price pursuant to this 
Section 8, the Company will promptly prepare a certificate signed by the 
Chairman, Chief Executive Officer or President, and by the Chief Financial 
Officer or an Assistant Chief Financial Officer or the Secretary or an 
Assistant Secretary, of the Company setting forth:  (i) the Purchase Price as 
so adjusted; (ii) the number of shares of Common Stock purchasable upon 
exercise of each Warrant, after such adjustment; and (iii) a brief statement 
of the facts accounting for such adjustment.  The Company will promptly file 
such certificate with the Warrant Agent and cause a brief summary thereof to 
be sent by ordinary first class mail to each Registered Holder at his last 
address as it shall appear on the registry books of the Warrant Agent.  No 
failure to mail such notice nor any defect therein or in the mailing thereof 
shall affect the validity thereof except as to the holder to whom the Company 
failed to mail such notice, or except as to the holder whose notice was 
defective.  The affidavit of an officer of the Warrant

                                       11

<PAGE>

Agent or the Secretary or an Assistant Secretary of the Company that such 
notice has been mailed shall, in the absence of fraud, be prima facie 
evidence of the facts stated therein. 

     (g)  No adjustment of the Purchase Price shall be made as a result of or 
in connection with the issuance or sale of shares of Common Stock if the 
amount of said adjustment shall be less than $.10, provided, however, that in 
such case, any adjustment that would otherwise be required then to be made 
shall be carried forward and shall be made at the time of and together with 
the next subsequent adjustment that shall amount, together with any 
adjustment so carried forward, to at least $.10.  In addition, Registered 
Holders shall not be entitled to cash dividends paid by the Company prior to 
the exercise of any Warrant or Warrants held by them. 

     (h)  No adjustment of the Purchase Price or the number of shares of 
Common Stock purchasable upon exercise of any Warrant shall be made as a 
result of or in connection with:  (A) the issuance or sale of shares of 
Common Stock pursuant to options, warrants, stock purchase agreements or 
convertible or exchangeable securities outstanding or in effect on the date 
hereof and on the terms described in the final prospectus relating to the 
public offering contemplated by the Underwriting Agreement; (B) the issuance, 
grant or sale of options under an incentive stock option plan to purchase 
shares of Common Stock in an aggregate amount not to exceed 166,000 shares; 
(C) the issuance, grant or sale of options, rights or warrants to subscribe 
for shares of Common Stock to a commercial lender in connection with a loan, 
credit facility or other form of indebtedness; or (D) the issuance or sale of 
shares of Common Stock in transactions involving acquisitions by the Company 
or an affiliated physician organization of all or a portion of the assets or 
equity ownership of unrelated business entities.

     (i)  Notwithstanding the foregoing, none of the provisions of this 
Section 8 shall apply to any of the Warrants issued to the Representative 
pursuant to the Representative's Warrant Agreement.  All adjustments to the 
exercise price of and the number and kind of securities covered by such 
Warrants shall be exclusively as set forth in Section 8 of the 
Representative's Warrant Agreement.

     SECTION 9.  REDEMPTION.

     (a)  Commencing on the Initial Warrant Redemption Date, the Company may, 
on not less than 30 days' prior written notice, redeem all, but not less than 
all, the Warrants at ten cents ($.10) per Warrant (subject to the same sorts 
of adjustments as are set forth in Section 8 with respect to the Purchase 
Price, predicated on a non-variable aggregate Redemption Price of $405,000), 
provided, however, that before any such call for redemption of Warrants can 
take place, the average closing bid price for the Common Stock as reported on 
Nasdaq, if the Common Stock is then traded on Nasdaq, (or the closing sale 
price, if the Common Stock is then traded on a national securities exchange) 
shall have equaled or exceeded $18.00 per share for any twenty (20) trading 
days within a period of thirty (30) consecutive trading days ending on the 
fifth trading day prior to the date on which the notice to Registered Holders 
contemplated hereby is given (subject to adjustment in the event of any stock 
splits or other similar events as provided in Section 8 hereof). 

     (b)  In case the Company shall exercise its right to redeem all of the 
Warrants, it shall give or cause to be given notice to the Registered Holders 
of the Warrants, by mailing to such Registered

                                       12

<PAGE>

Holders a notice of redemption, first class, postage prepaid, at their last 
address as shall appear on the records of the Warrant Agent.  Any notice 
mailed in the manner provided herein shall be conclusively presumed to have 
been duly given whether or not the Registered Holder receives such notice.  
Not less than five (5) business days prior to the mailing to the Registered 
Holders of the Warrants of the notice of redemption, the Company shall 
deliver or cause to be delivered to the Representative a similar notice 
telephonically and confirmed in writing together with a list of the 
Registered Holders (including their respective addresses and number of 
Warrants beneficially owned) to whom such notice of redemption has been or 
will be given. 

     (c)  The notice of redemption shall specify (i) the Redemption Price, 
(ii) the Redemption Date, which shall in no event be less than thirty (30) 
days after the date of mailing of such notice, (iii) the place where the 
Warrant Certificate shall be delivered and the Redemption Price shall be 
paid, and (iv) that the right to exercise the Warrant shall terminate at 5:00 
p.m. (New York time) on the business day immediately preceding the Redemption 
Date.  No failure to mail such notice nor any defect therein or in the 
mailing thereof shall affect the validity of the proceedings for such 
redemption except as to a holder (a) to whom notice was not mailed or (b) 
whose notice was defective.  An affidavit of the Warrant Agent or the 
Secretary or Assistant Secretary of the Company that notice of redemption has 
been mailed shall, in the absence of fraud, be prima facie evidence of the 
facts stated therein. 

     (d)  Any right to exercise a Warrant shall terminate at 5:00 p.m. (New 
York time) on the business day immediately preceding the Redemption Date.  
The Redemption Price payable to the Registered Holders shall be mailed to 
such persons at their addresses of record. 

     SECTION 10.  CONCERNING THE WARRANT AGENT.

     (a)  The Warrant Agent acts hereunder as agent and in a ministerial 
capacity for the Company and its duties shall be determined solely by the 
provisions hereof.  The Warrant Agent shall not, by issuing and delivering 
Warrant Certificates or by any other act hereunder, be deemed to make any 
representations as to the validity or value or authorization of the Warrant 
Certificates or the Warrants represented thereby or of any securities or 
other property delivered upon exercise of any Warrant or whether any stock 
issued upon exercise of any Warrant is fully paid and nonassessable.

     (b)  The Warrant Agent shall not at any time be under any duty or 
responsibility to any holder of Warrant Certificates to make or cause to be 
made any adjustment of the Purchase Price or the Redemption Price provided in 
this Agreement, or to determine whether any fact exists which may require any 
such adjustments, or with respect to the nature or extent of any such 
adjustments, when made, or with respect to the method employed in making the 
same.  It shall not (i) be liable for any recital or statement of fact 
contained herein or for any action taken, suffered or omitted by it in 
reliance on any Warrant Certificate or other document or instrument believed 
by it in good faith to be genuine and to have been signed or presented by the 
proper party or parties, (ii) be responsible for any failure on the part of 
the Company to comply with any of its covenants and obligations contained in 
this Agreement or in any Warrant Certificate, or (iii) be liable for any act 
or omission in connection with this Agreement except for its own negligence, 
bad faith or willful misconduct. 

                                       13

<PAGE>

     (c)  The Warrant Agent may at any time consult with counsel satisfactory 
to it (who may be counsel for the Company or for the Representative) and 
shall incur no liability or responsibility for any action taken, suffered or 
omitted by it in good faith in accordance with the opinion or advice of such 
counsel. 

     (d)  Any notice, statement, instruction, request, direction, order or 
demand of the Company shall be sufficiently evidenced by an instrument signed 
by the Chairman of the Board of Directors, Chief Executive Officer, President 
or any Vice President (unless other evidence in respect thereof is herein 
specifically prescribed).  The Warrant Agent shall not be liable for any 
action taken, suffered or omitted by it in accordance with such notice, 
statement, instruction, request, direction, order or demand reasonably 
believed by it to be genuine. 

     (e)  The Company agrees to pay the Warrant Agent reasonable compensation 
for its services hereunder and to reimburse it for its reasonable expenses 
hereunder; the Company further agrees to indemnify the Warrant Agent and save 
it harmless from and against any and all losses, expenses and liabilities, 
including judgments, costs and counsel fees, for anything done or omitted by 
the Warrant Agent in the execution of its duties and powers hereunder except 
losses, expenses and liabilities arising as a result of the Warrant Agent's 
negligence, bad faith or willful misconduct. 

     (f)  The Warrant Agent may resign its duties and be discharged from all 
further duties and liabilities hereunder (except liabilities arising as a 
result of the Warrant Agent's own negligence, bad  faith or willful 
misconduct), after giving 30 days' prior written notice to the Company.  At 
least 15 days prior to the date such resignation is to become effective, the 
Warrant Agent shall cause a copy of such notice of resignation to be mailed 
to the Registered Holder of each Warrant Certificate at the Company's 
expense.  Upon such resignation, or any inability of the Warrant Agent to act 
as such hereunder, the Company shall appoint in writing a new warrant agent.  
If the Company shall fail to make such appointment within a period of 15 days 
after it has been notified in writing of such resignation by the resigning 
Warrant Agent, then the Registered Holder of any Warrant Certificate may 
apply to any court of competent jurisdiction for the appointment of a new 
warrant agent.  Any new warrant agent, whether appointed by the Company or by 
such a court, shall be a bank or trust company having a capital and surplus, 
as shown by its last published report to its stockholders, of not less than 
$100,000,000 or a stock transfer company.  After acceptance in writing of 
such appointment by the new warrant agent is received by the Company, such 
new warrant agent shall be vested with the same powers, rights, duties and 
responsibilities as if it had been originally named herein as the Warrant 
Agent, without any further assurance, conveyance, act or deed; but if for any 
reason it shall be necessary or expedient to execute and deliver any further 
assurance, conveyance, act or deed, the same shall be done at the expense of 
the Company and shall be legally and validly executed and delivered by the 
resigning Warrant Agent.  Not later than the effective date of any such 
appointment the Company shall file notice thereof with the resigning Warrant 
Agent and shall forthwith cause a copy of such notice to be mailed to the 
Registered Holder of each Warrant Certificate. 

     (g)  Any corporation into which the Warrant Agent or any new warrant 
agent may be converted or merged, any corporation resulting from any 
consolidation to which the Warrant Agent or any new warrant agent shall be a 
party, or any corporation succeeding to the corporate trust business of the 
Warrant Agent or any new warrant agent shall be a successor warrant agent 
under this Agreement without any further act, provided that such corporation 
is eligible for appointment as

                                       14

<PAGE>

successor to the Warrant Agent under the provisions of the preceding 
paragraph.  Any such successor warrant agent shall promptly cause notice of 
its succession as warrant agent to be mailed to the Company and to the 
Registered Holders of each Warrant Certificate. 

     (h)  The Warrant Agent, its subsidiaries and affiliates, and any of its 
or their officers or directors, may buy and hold or sell Warrants or other 
securities of the Company and otherwise deal with the Company in the same 
manner and to the same extent and with like effect as though it were not 
Warrant Agent. Nothing herein shall preclude the Warrant Agent from acting in 
any other capacity for the Company or for any other legal entity. 

     (i)  The Warrant Agent shall retain for a period of two years from the 
date of exercise any Warrant Certificate received by it upon such exercise. 

     SECTION 11.  MODIFICATION OF AGREEMENT.

     The Warrant Agent and the Company may by supplemental agreement make any 
changes or corrections in this Agreement (i) that they shall deem appropriate 
to cure any ambiguity or to correct any defective or inconsistent provision 
or manifest mistake or error herein contained; or (ii) that they may deem 
necessary or desirable and which shall not adversely affect the interests of 
the holders of Warrant Certificates; provided, however, that this Agreement 
shall not otherwise be modified, supplemented or altered in any respect 
except with the consent in writing of the Registered Holders representing not 
less than 66-2/3% of the Warrants then outstanding; provided, further, that 
no change in the number or nature of the securities purchasable upon the 
exercise of any Warrant, or to increase the Purchase Price therefor or to 
accelerate the Warrant Expiration Date, shall be made without the consent in 
writing of the Registered Holder of the Warrant Certificate representing such 
Warrant, other than such changes as are presently specifically prescribed by 
this Agreement as originally executed.  In addition, this Agreement may not 
be modified, amended or supplemented without the prior written consent of the 
Representative, other than to cure any ambiguity or to correct any provision 
which is inconsistent with any other provision of this Agreement or to make 
any such change that is necessary or desirable and which shall not adversely 
affect the interests of the Representative and except as may be required by 
law. 

     SECTION 12.  NOTICES.

     All notices, requests, consents and other communications hereunder shall 
be in writing and shall be deemed to have been made when delivered or mailed 
first-class registered or certified mail, postage prepaid, as follows: if to 
the Registered Holder of a Warrant Certificate, at the address of such holder 
as shown on the registry books maintained by the Warrant Agent; if to the 
Company, at 515 S. Flower Street, Suite 1640, Los Angeles, California 90071, 
Attention: Jacob Y. Terner, M.D., Chief Executive Officer, or at such other 
address as may have been furnished to the Warrant Agent in writing by the 
Company; and if to the Warrant Agent, at the Corporate Office.  Copies of any 
notice delivered pursuant to this Agreement shall also be delivered to 
Security Capital Trading, Inc., ________________________, New York, New York, 
_____________________, Attention: General Counsel, or at such other address 
as may have been furnished to the Company and the Warrant Agent in writing.

     This Agreement shall be binding upon and inure to the benefit of the 
Company, the Representative, the Warrant Agent and their respective 
successors and assigns and the holders from time to time of Warrant 
Certificates or any of them.  Nothing in this Agreement is intended or shall 
be construed to confer upon any other person any right, remedy or claim, at 
equity or in law, or to impose upon any other person any duty, liability or 
obligation. 

     SECTION 15.  TERMINATION.

     This Agreement shall terminate at the close of business on the Warrant 
Expiration Date or such earlier date upon which all Warrants have been 
exercised or redeemed, except that the Warrant Agent shall account to the 
Company for cash held by it and the provisions of Section 10 hereof shall 
survive such termination.

                                REDEEMABLE WARRANT TO
                          PURCHASE ONE SHARE OF COMMON STOCK

                           PROSPECT MEDICAL HOLDINGS, INC.

                                     CUSIP ______


     THIS CERTIFIES THAT, FOR VALUE RECEIVED, _____________________________ 
or registered assigns (the "Registered Holder") is the owner of the number of 
Redeemable Warrants (the "Warrants") specified above.  Each Warrant initially 
entitles the Registered Holder to purchase, subject to the terms and 
conditions set forth in this Certificate and the Warrant Agreement (as 
hereinafter defined), one fully paid and nonassessable share of Common Stock, 
$.01 par value, of Prospect Medical Holdings, Inc., a Delaware corporation 
(the "Company"), at any time between _______________, 1999 (the "Initial 
Warrant Exercise Date"), and the Expiration Date (as hereinafter defined) 
upon the presentation and surrender of this Warrant Certificate with the 
Subscription Form on the reverse hereof duly executed, at the corporate 
office of American Stock Transfer and Trust Company, as Warrant Agent, or its 
successor (the "Warrant Agent"), accompanied by payment of $8.40 (the 
"Purchase Price"), subject to adjustment as provided in Section 8 of the 
Warrant Agreement, in lawful money of the United States of America in cash or 
by check made payable to the Warrant Agent for the account of the Company. 

     This Warrant Certificate and each Warrant represented hereby are issued 
pursuant to and are subject in all respects to the terms and conditions set 
forth in the Warrant Agreement (the "Warrant Agreement"), dated 
_________________, 1998 [date of the Prospectus], between the Company and the 
Warrant Agent. 

     In the event of certain contingencies provided for in the Warrant 
Agreement, the Purchase Price and the number of shares of Common Stock 
subject to purchase upon the exercise of each Warrant represented hereby are 
subject to modification or adjustment. 

     Each Warrant represented hereby is exercisable at the option of the 
Registered Holder, but no fractional interests will be issued.  In the case 
of the exercise of less than all the Warrants represented hereby, the Company 
shall cancel this Warrant Certificate upon the surrender hereof and shall 
execute and deliver a new Warrant Certificate or Warrant Certificates of like 
tenor, which the Warrant Agent shall countersign, for the balance of such 
Warrants.

<PAGE>

     The term "Expiration Date" shall mean 5:00 p.m. (New York time) on the 
date which is immediately preceding the fourth anniversary of the Initial 
Warrant Exercise Date.  If each such date shall in the State of New York be a 
holiday or a day on which the banks are authorized to close, then the 
Expiration Date shall mean 5:00 p.m. (New York time) on the next following 
day which in the State of New York is not a holiday or a day on which banks 
are authorized to close.

     The Company shall not be obligated to deliver any securities pursuant to 
the exercise of this Warrant unless a registration statement under the 
Securities Act of 1933, as amended (the "Act"), with respect to such 
securities is effective or an exemption thereunder is available.  The Company 
has covenanted and agreed that, to the extent required by applicable federal 
securities laws, it will file a registration statement under the Federal 
securities laws or a post-effective amendment to a then effective 
registration statement, use its reasonable best efforts to cause such filed 
registration statement to become effective and to keep any such effective 
registration statement current while any of the Warrants are outstanding, and 
deliver a prospectus which complies with Section 10(a)(3) of the Act to the 
Registered Holder exercising this Warrant.  This Warrant shall not be 
exercisable by a Registered Holder in any state where such exercise would be 
unlawful. 

     This Warrant Certificate is exchangeable, upon the surrender hereof by 
the Registered Holder at the Corporate Office of the Warrant Agent, for a new 
Warrant Certificate or Warrant Certificates of like tenor representing an 
equal aggregate number of Warrants, each of such new Warrant Certificates to 
represent such number of Warrants as shall be designated by such Registered 
Holder at the time of such surrender.  Upon due presentment and payment of 
any tax or other charge imposed in connection therewith or incident thereto, 
for registration of transfer of this Warrant Certificate at such office, a 
new Warrant Certificate or Warrant Certificates representing an equal 
aggregate number of Warrants will be issued to the transferee in exchange 
therefor, subject to the limitations provided in the Warrant Agreement.

     Prior to the exercise of any Warrant represented hereby, the Registered 
Holder shall not be entitled to any rights of a stockholder of the Company, 
including, without limitation, the right to vote or to receive dividends or 
other distributions, and shall not be entitled to receive any notice of any 
proceedings of the Company, except as provided in the Warrant Agreement.

     Subject to the provisions of the Warrant Agreement, this Warrant may be 
redeemed at the option of the Company, at a redemption price of $0.10 per 
Warrant (subject to adjustment as provided in the Warrant Agreement), at any 
time commencing after ______________, 1999 
[the first anniversary of the effective date of the Registration Statement], 
provided that the average closing bid price for the Common Stock as reported 
by Nasdaq (or the closing sale price, if the Common Stock is then traded on a 
national securities exchange), shall have equaled or exceeded $18.00 per 
share for any twenty (20) trading days within a period of thirty (30) 
consecutive trading days ending on the fifth trading day prior to the Notice 
of Redemption, as defined below (subject to adjustment in the event of any 
stock splits or other similar events).  Notice of redemption (the "Notice of 
Redemption") shall be given not later than the thirtieth day before the date 
fixed for redemption, all as provided in the Warrant Agreement.  On and after 
the date fixed for redemption, the Registered Holder shall have no rights 
with respect to the Warrants except to receive the redemption price upon 
surrender of this Warrant Certificate. 

                                        2

<PAGE>

     Prior to due presentment for registration of transfer hereof, the 
Company and the Warrant Agent may deem and treat the Registered Holder as the 
absolute owner hereof and of each Warrant represented hereby (notwithstanding 
any notations of ownership or writing hereon made by anyone other than a duly 
authorized officer of the Company or the Warrant Agent) for all purposes and 
shall not be affected by any notice to the contrary, except as provided in 
the Warrant Agreement. 

     This Warrant Certificate shall be governed by and construed in 
accordance with the laws of the State of New York without giving effect to 
conflicts of laws. 

     This Warrant Certificate is not valid unless countersigned by the 
Warrant Agent.

     IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to 
be duly executed, manually or in facsimile by two of its officers thereunto 
duly authorized and a facsimile of its corporate seal to be imprinted hereon.

                             WARRANT AGREEMENT

                     Dated as of _______________, 1998


<PAGE>

    REPRESENTATIVE'S WARRANT AGREEMENT dated as of _______________, 1998 
between PROSPECT MEDICAL HOLDINGS, INC., a Delaware corporation (the 
"Company"), and SECURITY CAPITAL TRADING, INC. (hereinafter referred to 
variously as the "Holder" or "Holders" or the "Representative"). 

                             W I T N E S S E T H:

    WHEREAS, the Company proposes to issue to the Representative warrants 
("Warrants") to purchase up to an aggregate of 300,000 shares of Common 
Stock, $0.01 par value, of the Company and/or 300,000 redeemable Common Stock 
purchase warrants of the Company ("Redeemable Warrants"), each Redeemable 
Warrant to purchase one additional share of Common Stock; and 

    WHEREAS, the Representative has agreed pursuant to the underwriting 
agreement (the "Underwriting Agreement") dated as of the date hereof between 
the Company and the several Underwriters listed therein to act as the 
Representative in connection with the Company's proposed public offering of 
up to 3,000,000 shares of Common Stock and 3,000,000 Redeemable Warrants (the 
"Public Warrants") at a public offering price of $_____ per share of Common 
Stock and $______ per Redeemable Warrant (the "Public Offering"); and 

    WHEREAS, the Warrants to be issued pursuant to this Agreement will be 
issued on the Closing Date (as such term is defined in the Underwriting 
Agreement) by the Company to the Representative in consideration for, and as 
part of the Representative's compensation in connection with, the 
Representative acting as the Representative pursuant to the Underwriting 
Agreement; 

    NOW, THEREFORE, in consideration of the premises, the payment by the 
Representative to the Company of an aggregate of thirty  dollars ($30.00), 
the agreements herein set forth and other good and valuable consideration, 
hereby acknowledged, the parties hereto agree as follows: 

    1.   GRANT.  The Representative (or its designees) is hereby granted the 
right to purchase, at any time from _______________, 1999 [one year after date 
of this Agreement], until 5:30 P.M., New York time, on ___________, 2003 [five 
years after date of this Agreement], up to an aggregate of 300,000 shares of 
Common Stock and/or 300,000 Redeemable Warrants at an initial exercise price 
(subject to adjustment as provided in Section 8 hereof) of $_____ per share of 
Common Stock [120% of initial public offering price per share of Common Stock], 
and $_____ per Redeemable Warrant [120% of initial public offering price per 
Redeemable Warrant], subject to the terms and conditions of this Agreement. One 
Redeemable Warrant is exercisable to purchase one additional share of Common 
Stock at an initial exercise price of $_____ [140% of initial public offering 
price per share of the Common Stock] from ______________, 1999 [one year after 
date of this Agreement] until 5:30 p.m. New York time on ____________, 2003[5 
years after date of this Agreement], at which time the Redeemable Warrants 
shall expire. Except as set forth herein, the shares of Common Stock and the 
Redeemable Warrants issuable upon exercise of the Warrants are in all respects 
identical to the shares of Common Stock and the Public Warrants being purchased 
by the Underwriters for resale to the public pursuant to the terms and 
provisions of the Underwriting Agreement. The shares of Common Stock and the 
Redeemable Warrants issuable upon exercise of the Warrants are sometimes 
hereinafter referred to collectively as the "Securities." 


<PAGE>

    2.   WARRANT CERTIFICATES.  The warrant certificates (the "Warrant 
Certificates") delivered and to be delivered pursuant to this Agreement shall 
be in the form set forth in Exhibit A, attached hereto and made a part 
hereof, with such appropriate insertions, omissions, substitutions, and other 
variations as required or permitted by this Agreement.
 
    3.   EXERCISE OF WARRANT. 

         3.1  METHOD OF EXERCISE.  The Warrants initially are exercisable at 
an initial exercise price per share of Common Stock and per Redeemable 
Warrant set forth in Section 6 hereof payable by certified or official bank 
check in New York Clearing House funds, subject to adjustment as provided in 
Section 8 hereof. Upon surrender of a Warrant Certificate with the annexed 
Form of Election to Purchase Pursuant to Section 3.1 duly executed, together 
with payment of the Exercise Price (as hereinafter defined) for the shares of 
Common Stock and/or the Redeemable Warrants to be purchased at the Company's 
principal executive offices in California (presently located at 515 South 
Flower Street, Suite 1640, Los Angeles, California 90071) the registered 
holder of a Warrant Certificate ("Holder" or "Holders") shall be entitled to 
receive a certificate or certificates for the shares of Common Stock so 
purchased and a certificate or certificates for the Redeemable Warrants so 
purchased. The purchase rights represented by each Warrant Certificate are 
exercisable at the option of the Holder thereof, in whole or in part (but not 
as to fractional shares of the Common Stock and Redeemable Warrants 
underlying the Warrants). In the event the Company redeems all of the Public 
Warrants, then the Warrants may only be exercised if such exercise is 
accompanied by the simultaneous exercise of the Redeemable Warrant(s) 
underlying the Warrants being so exercised. Warrants may be exercised to 
purchase all or part of the shares of Common Stock together with an equal or 
unequal number of the Redeemable Warrants represented thereby. In the case of 
the purchase of less than all the shares of Common Stock and/or the 
Redeemable Warrants purchasable under any Warrant Certificate, the Company 
shall cancel said Warrant Certificate upon the surrender thereof and shall 
execute and deliver a new Warrant Certificate of like tenor for the balance 
of the shares of Common Stock and Redeemable Warrants purchasable thereunder. 

         3.2  EXERCISE BY SURRENDER OF WARRANT.  In addition to the method of 
payment set forth in Section 3.1 and in lieu of any cash payment required 
thereunder, the Holder(s) of the Warrants shall have the right at any time 
and from time to time to exercise the Warrants in full or in part by 
surrendering the Warrant Certificate in the manner specified in Section 3.1 
hereof. The number of shares of Common Stock to be issued pursuant to this 
Section 3.2 shall be equal to the difference between (a) the number of shares 
of Common Stock in respect of which the Warrants are exercised and (b) a 
fraction, the numerator of which shall be the number of shares of Common 
Stock in respect of which the Warrants are exercised multiplied by the 
Exercise Price and the denominator of which shall be the Market Price (as 
defined in Section 3.3 hereof) of the shares of Common Stock. The number of 
Redeemable Warrants to be issued pursuant to this Section 3.2 shall be equal 
to the difference between (a) the number of Redeemable Warrants in respect of 
which the Warrants are exercised and (b) a fraction, the numerator of which 
shall be the number of Redeemable Warrants in respect of which the Warrants 
are exercised multiplied by the Exercise Price and the denominator of which 
shall be the Market Price (as defined in Section 3.3 hereof) of the 
Redeemable Warrants. Solely for the purposes of this paragraph, Market Price 
shall be calculated either (i) on the date on which the Form of Election To 
Purchase Pursuant to Section 3.2 annexed to the Warrant Certificate is deemed 
to have been sent to the Company pursuant to Section 14 hereof ("Notice 
Date") or (ii) 


                                      2

<PAGE>

as the average of the Market Prices for each of the five trading days 
preceding the Notice Date, whichever of (i) or (ii) is greater. 

         3.3  DEFINITION OF MARKET PRICE.   As used herein, the phrase 
"Market Price" at any date shall be deemed to be (i) when referring to the 
Common Stock, the last reported sale price, or, in case no such reported sale 
takes place on such day, the average of the last reported sale prices for the 
last three trading days, in either case as officially reported by the 
principal securities exchange on which the Common Stock is listed or admitted 
to trading or by the Nasdaq SmallCap Market or the Nasdaq National Market (in 
either case, "Nasdaq") or, if the Common Stock is not listed or admitted to 
trading on any national securities exchange or quoted by Nasdaq, the average 
closing bid price as furnished by the National Association of Securities 
Dealers, Inc. ("NASD") through Nasdaq or a similar organization if Nasdaq is 
no longer reporting such information, or if none of the foregoing conditions 
applies, as determined in good faith (using customary valuation methods) by 
resolution of the members of the Board of Directors of the Company, based on 
the best information available to it, or (ii) when referring to a Redeemable 
Warrant, the last reported sales price, or, in the case no such reported sale 
takes place on such day, the average of the last reported sale prices for the 
last three trading days, in either case as officially reported by the 
principal securities exchange on which the Redeemable Warrants are listed or 
admitted to trading or by Nasdaq, or, if the Redeemable Warrants are not 
listed or admitted to trading on any national securities exchange or quoted 
by Nasdaq, the average closing bid price as furnished by the NASD through 
Nasdaq or a similar organization if Nasdaq is no longer reporting such 
information, or if none of the foregoing conditions applies, the Market Price 
of a Redeemable Warrant shall equal the difference between the Market Price 
of the Common Stock and the Exercise Price of the Redeemable Warrant. 

    4.   ISSUANCE OF CERTIFICATES.  Upon the exercise of the Warrants, the 
issuance of certificates for shares of Common Stock and Redeemable Warrants 
and/or other securities, properties or rights underlying such Warrants and, 
upon the exercise of the Redeemable Warrants, the issuance of certificates 
for shares of Common Stock and/or other securities, properties or rights 
underlying such Redeemable Warrants, shall be made forthwith (and in any 
event within five business days thereafter) without charge to the Holder 
thereof including, without limitation, any tax which may be payable in 
respect of the issuance thereof, and such certificates shall (subject to the 
provisions of Sections 5 and 7 hereof) be issued in the name of, or in such 
names as may be directed by, the Holder thereof; provided, however, that the 
Company shall not be required to pay any tax which may be payable in respect 
of any transfer involved in the issuance and delivery of any such 
certificates in a name other than that of the Holder, and the Company shall 
not be required to issue or deliver such certificates unless or until the 
person or persons requesting the issuance thereof shall have paid to the 
Company the amount of such tax or shall have established to the satisfaction 
of the Company that such tax has been paid. 

         The Warrant Certificates and the certificates representing the 
shares of Common Stock and the Redeemable Warrants underlying the Warrants 
and the shares of Common Stock underlying the Redeemable Warrants (and/or 
other securities, property or rights issuable upon the exercise of the 
Warrants or the Redeemable Warrants) shall be executed on behalf of the 
Company by the manual or facsimile signature of the then Chairman or Vice 
Chairman of the Board of Directors or President or Vice President of the 
Company. Warrant Certificates shall be dated the date of execution by the 
Company upon initial issuance, division, exchange, substitution or transfer. 


                                      3

<PAGE>

Certificates representing the shares of Common Stock and Redeemable Warrants, 
and the shares of Common Stock underlying each Redeemable Warrant (and/or 
other securities, property or rights issuable upon exercise of the Warrants) 
shall be dated as of the Notice Date (regardless of when executed or 
delivered) and dividend-bearing securities so issued shall accrue dividends 
from the Notice Date. 

    5.   RESTRICTION ON TRANSFER OF WARRANTS.  The Holder of a Warrant 
Certificate, by its acceptance thereof, covenants and agrees that the 
Warrants are being acquired as an investment and not with a view to the 
distribution thereof; that the Warrants may not be sold, transferred, 
assigned, hypothecated or otherwise disposed of, in whole or in part, for a 
period of one year from the date hereof, except to officers of the 
Representative. 

    6.   EXERCISE PRICE. 

         6.1  INITIAL AND ADJUSTED EXERCISE PRICE.  Except as otherwise 
provided in Section 8 hereof, the initial exercise price of each Warrant 
shall be $______ per share of Common Stock [120% of the initial public 
offering price of the Common Stock] and $_____ per Redeemable Warrant 
[120% of the initial public offering price of the Redeemable Warrants]. The 
adjusted exercise price shall be the price which shall result from time to 
time from any and all adjustments of the initial exercise price in accordance 
with the provisions of Section 8 hereof. Any transfer of a Warrant shall 
constitute an automatic transfer and assignment of the registration rights 
set forth in Section 7 hereof with respect to the Securities or other 
securities, properties or rights underlying the Warrants. 

         6.2  EXERCISE PRICE.  The term "Exercise Price" herein shall mean 
the initial exercise price or the adjusted exercise price, depending upon the 
context or unless otherwise specified. 

    7.   REGISTRATION RIGHTS. 

         7.1  REGISTRATION UNDER THE SECURITIES ACT OF 1933.  The Warrants, 
the shares of Common Stock and Redeemable Warrants, or other securities 
issuable upon exercise of the Warrants, and the shares of Common Stock or 
other securities issuable upon exercise of the Redeemable Warrants 
(collectively, the "Warrant Securities") have been registered under the 
Securities Act of 1933, as amended (the "Act") pursuant to the Company's 
Registration Statement on Form S-1 (Registration No. 333-            ) (the 
"Registration Statement").  All of the representations and warranties of the 
Company contained in the Underwriting Agreement relating to the Registration 
Statement, the Preliminary Prospectus and Prospectus (as such terms are 
defined in the Underwriting Agreement) and made as of the dates provided 
therein, are incorporated by reference herein. The Company agrees and 
covenants promptly to file post-effective amendments to such Registration 
Statement as may be necessary in order to maintain its effectiveness and 
otherwise to take such action as may be necessary to maintain the 
effectiveness of the Registration Statement as long as any Warrants are 
outstanding. In the event that, for any reason, whatsoever, the Company shall 
fail to maintain the effectiveness of the Registration Statement, the 
certificates representing the Warrant Securities shall bear the following 
legend: 

         The securities represented by this certificate have not been registered


                                      4

<PAGE>

         under the Securities Act of 1933, as amended ("Act"), and may not be 
         offered or sold except pursuant to (i) an effective registration 
         statement under the Act, (ii) to the extent applicable, Rule 144 under 
         the Act (or any similar rule under such Act relating to the disposition
         of securities), or (iii) an opinion of counsel, if such opinion 
         shall be reasonably satisfactory to counsel to the issuer, that an 
         exemption from registration under such Act is available. 

         7.2  PIGGYBACK REGISTRATION.  If, at any time commencing after the 
date hereof and expiring seven years thereafter, the Company proposes to 
register any of its securities under the Act (other than pursuant to Form 
S-4, Form S-8 or a comparable registration statement), the Company will give 
written notice by registered mail, at least 30 days prior to the filing of 
each such registration statement, to the Representative and to all other 
Holders of the Warrants and/or Warrant Securities of its intention to do so.  
If the Representative or other Holders of the Warrants and/or Warrant 
Securities notify the Company within 20 business days after receipt of any 
such notice of its or their desire to include any such Warrant Securities in 
such proposed registration statement, the Company shall afford the 
Representative and such Holders of the Warrants and/or Warrant Securities the 
opportunity to have any such Warrant Securities registered under such 
registration statement, unless and to the extent that the managing 
underwriter, if any, of the offering covered by such registration statement 
determines that the inclusion of such securities therein would impair the 
success of said offering.

         Notwithstanding the provisions of this Section 7.2, the Company 
shall (i) have the right at any time after it shall have given written notice 
pursuant to this Section 7.2 (irrespective of whether a written request for 
inclusion of any such securities shall have been made) to elect not to file 
any such proposed registration statement, or to withdraw the same after the 
filing but prior to the effective date thereof, and (ii) have no obligation 
pursuant to this Section 7.2 to the extent that, at the time the registration 
statement is proposed to be filed, the holders of such securities may freely 
sell such securities pursuant to the Rules and Regulations. 

         7.3  DEMAND REGISTRATION. 

              (a)  At any time commencing after the date hereof and expiring 
five years thereafter, the Holders of the Warrants and/or Warrant Securities 
representing a "Majority" (as hereinafter defined) of such securities 
(assuming the exercise of all of the Warrants) shall have the right (which 
right is in addition to the registration rights under Section 7.2 hereof), 
exercisable by written notice to the Company, to have the Company prepare and 
file with the Securities and Exchange Commission (the "Commission"), on one 
occasion, a registration statement and such other documents, including a 
prospectus, as may be necessary in the opinion of both counsel for the 
Company and counsel for the Representative and Holders, in order to comply 
with the provisions of the Act, so as to permit a public offering and sale of 
their respective Warrant Securities for six consecutive months by such 
Holders and any other Holders of the Warrants and/or Warrant Securities who 
notify the Company within ten days after receiving notice from the Company of 
such request. 

              (b)  The Company covenants and agrees to give written notice of
any 


                                      5

<PAGE>

registration request under this Section 7.3 by any Holder or Holders to all 
other registered Holders of the Warrants and the Warrant Securities within 
ten days from the date of the receipt of any such registration request. 

              (c)  Notwithstanding anything to the contrary contained herein, 
if the Company shall not have filed a registration statement for the Warrant 
Securities within the time period specified in Section 7.4(a) hereof pursuant 
to the written notice specified in Section 7.3(a) of a Majority of the 
Holders of the Warrants and/or Warrant Securities, the Company may, at its 
option, upon the written notice of election of a Majority of the Holders of 
the Warrants and/or Warrant Securities requesting such registration, 
repurchase (i) any and all Warrant Securities of such Holders at the higher 
of the Market Price per share of Common Stock and per Redeemable Warrant, 
determined as of (x) the date of the notice sent pursuant to Section 7.3(a) 
or (y) the expiration of the period specified in Section 7.4(a) and (ii) any 
and all Warrants of such Holders at such Market Price less the Exercise Price 
of such Warrant. Such repurchase shall be in immediately available funds and 
shall close within two (2) days after the later of (i) the expiration of the 
period specified in Section 7.4(a) or (ii) the delivery of the written notice 
of election specified in this Section 7.3(c). 

         7.4  COVENANTS OF THE COMPANY WITH RESPECT TO REGISTRATION.  In 
connection with any registration under Section 7.2 or 7.3 hereof, the Company 
covenants and agrees as follows: 

              (a)  The Company shall use its best efforts to file a 
registration statement within 90 days of receipt of a demand therefor 
pursuant to Section 7.3 hereof, shall use its reasonable best efforts to have 
any registration statements declared effective at the earliest practicable 
time, and shall furnish each Holder desiring to sell Warrant Securities such 
number of prospectuses as shall reasonably be requested. 

              (b)  The Company shall pay all costs (excluding fees and 
expenses of Holder(s)' counsel and any underwriting or selling commissions), 
fees and expenses in connection with all registration statements filed 
pursuant to Sections 7.2 and 7.3(a) hereof including, without limitation, the 
Company's legal and accounting fees, printing expenses and blue sky fees and 
expenses. 

              (c)  The Company will take all necessary action which may be 
required in qualifying or registering the Warrant Securities included in a 
registration statement for offering and sale under the securities or blue sky 
laws of such states as reasonably are requested by the Holder(s), provided 
that the Company shall not be obligated to execute or file any general 
consent to service of process or to qualify as a foreign corporation to do 
business under the laws of any such jurisdiction. 

              (d)  The Company shall indemnify the Holder(s) of the Warrant 
Securities to be sold pursuant to any registration statement hereunder and 
each person, if any, who controls such Holders within the meaning of Section 
15 of the Act or Section 20(a) of the Securities Exchange Act of 1934, as 
amended ("Exchange Act"), against all loss, claim, damage, expense or 
liability (including all expenses reasonably incurred in investigating, 
preparing or defending against any claim whatsoever) to which any of them may 
become subject under the Act, the Exchange Act or otherwise, arising from 
such registration statement but only to the same extent and with the same 


                                      6

<PAGE>

effect as the provisions pursuant to which the Company has agreed to 
indemnify each of the Underwriters contained in Section 7 of the Underwriting 
Agreement. 

              (e)  The Holder(s) of the Warrant Securities to be sold 
pursuant to a registration statement hereunder, and their successors and 
assigns, shall severally, and not jointly, indemnify the Company, its 
officers and directors and each person, if any, who controls the Company 
within the meaning of Section 15 of the Act or Section 20(a) of the Exchange 
Act, against all loss, claim, damage, expense or liability (including all 
expenses reasonably incurred in investigating, preparing or defending against 
any claim whatsoever) to which they may become subject under the Act, the 
Exchange Act or otherwise, arising from information furnished by or on behalf 
of such Holders, or their successors or assigns, for specific inclusion in 
such registration statement to the same extent and with the same effect as 
the provisions contained in Section 7 of the Underwriting Agreement pursuant 
to which the Underwriters have agreed to indemnify the Company. 

              (f)  Nothing contained in this Agreement shall be construed as 
requiring the Holder(s) to exercise their Warrants prior to the initial 
filing of any registration statement or the effectiveness thereof. 

              (g)  The Company shall not permit the inclusion of any 
securities other than the Warrant Securities to be included in any 
registration statement filed pursuant to Section 7.3 hereof, or permit any 
other registration statement to be filed during the effectiveness of a 
registration statement filed pursuant to Section 7.3 hereof (other than 
registrations on Form S-4 or S-8), without the prior written consent of the 
Holders of the Warrants and Warrant Securities representing a Majority of 
such securities covered by such registration statement. 

              (h)  The Company shall furnish to each Holder participating in 
an offering covered by a registration statement hereunder and to each 
underwriter, if any, a signed counterpart, addressed to such Holder or 
underwriter, of (i) an opinion of counsel to the Company, dated the effective 
date of such registration statement (and, if such registration relates to an 
underwritten public offering, an opinion dated the date of the closing under 
the underwriting agreement) relating to the due incorporation of the Company, 
the validity of the shares being sold and the due execution and delivery by 
the Company of the underwriting agreement, if any, and (ii) a "cold comfort" 
letter dated the effective date of such registration statement (and, if such 
registration relates to an underwritten public offering, a letter dated the 
date of the closing under the underwriting agreement) signed by the 
independent public accountants who have issued a report on the Company's 
financial statements included in such registration statement, covering 
substantially the same matters with respect to such registration statement 
(and the prospectus included therein) and, with respect to events subsequent 
to the date of such financial statements, as are customarily covered in 
accountants' "cold comfort" letters delivered to underwriters in underwritten 
public offerings of securities. 

              (i)  The Company shall as soon as practicable, and in any event 
within 15 months after the effective date of the registration statement, make 
"generally available to its security holders" (within the meaning of Rule 158 
under the Act) an earnings statement (which need not be audited) complying 
with Section 11(a) of the Act and covering a period of at least 12 
consecutive months beginning after the effective date of the registration 
statement.

<PAGE>

              (j)  The Company shall deliver promptly to each Holder 
participating in the offering requesting the correspondence and memoranda 
described below and to the managing underwriters, copies of all 
correspondence between the Commission and the Company, its counsel or 
auditors and all Company-prepared memoranda relating to discussions with the 
Commission or its staff with respect to the registration statement and permit 
each Holder and underwriter to do such investigation, upon reasonable advance 
notice, with respect to information contained in or omitted from the 
registration statement as it deems reasonably necessary to comply with 
applicable securities laws or rules of the NASD.  Such investigation shall 
include access to books, records and properties and opportunities to discuss 
the business of the Company with its officers and independent auditors, all 
to such reasonable extent and at such reasonable times and as often as any 
such Holder or underwriter shall reasonably request. 

              (k)  The Company shall enter into an underwriting agreement 
with the managing underwriters selected for such underwriting by Holders 
holding a Majority of the Warrant Securities requested pursuant to Section 
7.3(a) to be included in such underwriting, which may be the Representative. 
Such agreement shall be satisfactory in form and substance to the Company, 
each Holder and such managing underwriter(s), and shall contain such 
representations, warranties and covenants by the Company and such other terms 
as are customarily contained in agreements of that type used by the managing 
underwriter(s). The Holders shall be parties to any underwriting agreement 
relating to an underwritten sale of their Warrant Securities whether pursuant 
to Section 7.2 or Section 7.3(a) and may, at their option, require that any 
or all of the representations, warranties and covenants of the Company to or 
for the benefit of such underwriter(s) shall also be made to and for the 
benefit of such Holders. Such Holders shall not be required to make any 
representations or warranties to or agreements with the Company or the 
underwriter(s) except as they may relate to such Holders and their intended 
methods of distribution, or as otherwise provided for herein. 

              (l)  For purposes of this Agreement, the term "Majority" in 
reference to the Holders of Warrants or Warrant Securities, shall mean in 
excess of 50% of the then outstanding Warrants or Warrant Securities that (i) 
are not held by the Company, an affiliate, officer, creditor, employee or 
agent thereof or any of their respective affiliates, members of their family, 
persons acting as nominees therefor or in conjunction therewith and (ii) have 
not been resold to the public pursuant to a registration statement filed with 
the Commission under the Act. 

    8.   ADJUSTMENTS TO EXERCISE PRICE AND NUMBER OF SECURITIES. 

         8.1  SUBDIVISION AND COMBINATION.  In case the Company shall at any 
time subdivide or combine the outstanding shares of Common Stock, the 
Exercise Price shall forthwith be proportionately decreased in the case of 
subdivision or increased in the case of combination. 

         8.2  STOCK DIVIDENDS AND DISTRIBUTIONS.  In case the Company shall 
pay a dividend in, or make a distribution of, shares of Common Stock or of 
the Company's capital stock convertible into Common Stock, the Exercise Price 
shall forthwith be proportionately decreased. An adjustment made pursuant to 
this Section 8.2 shall be made as of the record date for the subject stock 
dividend or distribution. 

         8.3  ADJUSTMENT IN NUMBER OF SECURITIES.  Upon each adjustment of 
the Exercise 


                                      8

<PAGE>

Price pursuant to the provisions of this Section 8, the number of Warrant 
Securities issuable upon the exercise at the adjusted exercise price of each 
Warrant shall be adjusted to the nearest full amount by multiplying a number 
equal to the Exercise Price in effect immediately prior to such adjustment by 
the number of Warrant Securities issuable upon exercise of the Warrants 
immediately prior to such adjustment and dividing the product so obtained by 
the adjusted Exercise Price. 

         8.4  DEFINITION OF COMMON STOCK.  For the purpose of this Agreement, 
the term "Common Stock" shall mean (i) the class of stock designated as 
Common Stock in the Certificate of Incorporation of the Company as may be 
amended as of the date hereof, or (ii) any other class of stock resulting 
from successive changes or reclassifications of such Common Stock consisting 
solely of changes in par value, or from par value to no par value, or from no 
par value to par value. 

         8.5  MERGER OR CONSOLIDATION.  In case of any consolidation of the 
Company with, or merger of the Company with, or merger of the Company into, 
another corporation (other than a consolidation or merger which does not 
result in any reclassification or change of the outstanding Common Stock), 
the corporation formed by such consolidation or merger shall execute and 
deliver to the Holder a supplemental warrant agreement providing that the 
holder of each Warrant then outstanding or to be outstanding shall have the 
right thereafter (until the expiration of such Warrant) to receive, upon 
exercise of such Warrant, the kind and amount of shares of stock and other 
securities and property receivable upon such consolidation or merger, by a 
holder of the number of securities of the Company for which such Warrant 
might have been exercised immediately prior to such consolidation or merger. 
Such supplemental warrant agreement shall provide for adjustments which shall 
be identical to the adjustments provided in Section 8. The above provision of 
this subsection shall similarly apply to successive consolidations or 
mergers. 

         8.6  NO ADJUSTMENT OF EXERCISE PRICE IN CERTAIN CASES.  No 
adjustment of the Exercise Price shall be made if the amount of said 
adjustment shall be less than two cents ($.02) per Warrant, provided, 
however, that in such case any adjustment that would otherwise be required 
then to be made shall be carried forward and shall be made at the time of and 
together with the next subsequent adjustment which, together with any 
adjustment so carried forward, shall amount to at least two cents ($.02) per 
Warrant. 

    9.   EXCHANGE AND REPLACEMENT OF WARRANT CERTIFICATES.  Each Warrant 
Certificate is exchangeable without expense, upon the surrender thereof by 
the registered Holder at the principal executive office of the Company, for a 
new Warrant Certificate or Warrant Certificates of like tenor and date 
representing in the aggregate the right to purchase the same number of 
Warrant Securities in such denominations as shall be designated by the Holder 
thereof at the time of such surrender. 

         Upon receipt by the Company of evidence reasonably satisfactory to 
it of the loss, theft, destruction or mutilation of any Warrant Certificate, 
and, in case of loss, theft or destruction, of indemnity or security 
reasonably satisfactory to it, and reimbursement to the Company of all 
reasonable expenses incidental thereto, and upon surrender and cancellation 
of the Warrants, if mutilated, the Company will make and deliver a new 
Warrant Certificate of like tenor, in lieu thereof. 

    10.  ELIMINATION OF FRACTIONAL INTERESTS.  The Company shall not be 
required to issue 


                                      9

<PAGE>

certificates representing fractions of shares of Common Stock or Redeemable 
Warrants upon the exercise of the Warrants, nor shall it be required to issue 
scrip or pay cash in lieu of fractional interests, it being the intent of the 
parties that all fractional interests shall be eliminated by rounding any 
fraction up or down to the nearest whole number of shares of Common Stock or 
Redeemable Warrants or other securities, properties or rights. 

    11.  RESERVATION AND LISTING OF SECURITIES.  The Company shall at all 
times reserve and keep available out of its authorized shares of Common 
Stock, solely for the purpose of issuance upon the exercise of the Warrants 
and the Redeemable Warrants, such number of shares of Common Stock or other 
securities, properties or rights as shall be issuable upon the exercise 
thereof.  The Company covenants and agrees that, upon exercise of the 
Warrants and payment of the Exercise Price therefor, all shares of Common 
Stock, Redeemable Warrants and other securities issuable upon such exercise 
shall be duly and validly issued, fully paid, non-assessable and not subject 
to the preemptive rights of any stockholder.  The Company further covenants 
and agrees that upon exercise of the Redeemable Warrants underlying the 
Warrants and payment of the respective Redeemable Warrant exercise price 
therefor, all shares of Common Stock and other securities issuable upon such 
exercise shall be duly and validly issued, fully paid, non-assessable and not 
subject to the preemptive rights of any stockholder.  As long as the Warrants 
shall be outstanding, the Company shall use its reasonable best efforts to 
cause all shares of Common Stock issuable upon the exercise of the Warrants 
and Redeemable Warrants and all Redeemable Warrants underlying the Warrants 
to be listed (subject to official notice of issuance) on all securities 
exchanges on which the Common Stock or the Public Warrants issued to the 
public in connection herewith may then be listed and/or quoted on Nasdaq. 

    12.  NOTICES TO WARRANT HOLDERS.  Nothing contained in this Agreement 
shall be construed as conferring upon the Holders the right to vote or to 
consent or to receive notice as a stockholder in respect of any meetings of 
stockholders for the election of directors or any other matter, or as having 
any rights whatsoever as a stockholder of the Company.  If, however, at any 
time prior to the expiration of the Warrants and their exercise, any of the 
following events shall occur: 

         (a)  the Company shall take a record of the holders of its shares of 
Common Stock for the purpose of entitling them to receive a dividend or 
distribution payable otherwise than in cash, or a cash dividend or 
distribution payable otherwise than out of current or retained earnings or 
capital surplus (in accordance with applicable law), as indicated by the 
accounting treatment of such dividend or distribution on the books of the 
Company; or 

         (b)  the Company shall offer to all the holders of its Common Stock 
any additional shares of capital stock of the Company or securities 
convertible into or exchangeable for shares of capital stock of the Company, 
or any option, right or warrant to subscribe therefor; or 

         (c)  a dissolution, liquidation or winding up of the Company (other 
than in connection with a consolidation or merger) or a sale of all or 
substantially all of its property, assets and business as an entirety shall 
be proposed; 

then, in any one or more of said events, the Company shall give written 
notice of such event at least 30 days prior to the date fixed as a record 
date or the date of closing the transfer books for the 


                                      10

<PAGE>

determination of the stockholders entitled to such dividend, distribution, 
convertible or exchangeable securities or subscription rights, or entitled to 
vote on such proposed dissolution, liquidation, winding up or sale.  Such 
notice shall specify such record date or the date of closing the transfer 
books, as the case may be. Failure to give such notice or any defect therein 
shall not affect the validity of any action taken in connection with the 
declaration or payment of any such dividend, or the issuance of any 
convertible or exchangeable securities, or subscription rights, options or 
warrants, or any proposed dissolution, liquidation, winding up or sale. 

    13.  REDEEMABLE WARRANTS.  The form of the certificate representing 
Redeemable Warrants (and the form of election to purchase shares of Common 
Stock upon the exercise of Redeemable Warrants and the form of assignment 
printed on the reverse thereof) shall be substantially as set forth in 
Exhibit "A" to the Warrant Agreement dated as of the date hereof by and 
between the Company and American Stock Transfer and Trust Company (the 
"Redeemable Warrant Agreement"). Each Redeemable Warrant issuable upon 
exercise of the Warrants shall evidence the right to initially purchase a 
fully paid and non-assessable share of Common Stock at an initial purchase 
price of $_____ per share [140% of the initial public offering price per share 
of Common Stock] from ________________, 1999 [one year after date of 
Prospectus] until 5:30 p.m. New York time on ________________, 2003 [five years 
after date of Prospectus] at which time the Redeemable Warrants, unless the 
exercise period has been extended, shall expire. The exercise price of the 
Redeemable Warrants and the number of shares of Common Stock issuable upon the 
exercise of the Redeemable Warrants are subject to adjustment, whether or not 
the Warrants have been exercised and the Redeemable Warrants have been issued, 
in the manner and upon the occurrence of the events set forth in Section 8 of 
the Redeemable Warrant Agreement, which is hereby incorporated herein by 
reference and made a part hereof as if set forth in its entirety herein. Subject
to the provisions of this Agreement and upon issuance of the Redeemable Warrants
underlying the Warrants, each registered holder of such Redeemable Warrant 
shall have the right to purchase from the Company (and the Company shall issue 
to such registered holders) up to the number of fully paid and non-assessable 
shares of Common Stock (subject to adjustment as provided herein and in the 
Redeemable Warrant Agreement), free and clear of all preemptive rights of 
stockholders, provided that such registered holder complies with the terms 
governing exercise of the Redeemable Warrant set forth in the Redeemable 
Warrant Agreement, and pays the applicable exercise price, determined in 
accordance with the terms of the Redeemable Warrant Agreement.  Upon exercise 
of the Redeemable Warrants, the Company shall forthwith issue to the 
registered holder of any such Redeemable Warrant in his name or in such name 
as may be directed by him, certificates for the number of shares of Common 
Stock so purchased.  Except as otherwise provided in this Agreement, the 
Redeemable Warrants underlying the Warrants shall be governed in all respects 
by the terms of the Redeemable Warrant Agreement.  The Redeemable Warrants 
shall be transferable in the manner provided in the Redeemable Warrant 
Agreement, and upon any such transfer, a new Redeemable Warrant Certificate 
shall be issued promptly to the transferee. The Company covenants to, and 
agrees with, the Holder(s) that without the prior written consent of the 
Holder(s), which will not be unreasonably withheld, the Redeemable Warrant 
Agreement will not be modified, amended, canceled, altered or superseded, and 
that the Company will send to each Holder, irrespective of whether or not the 
Warrants have been exercised, any and all notices required by the Redeemable 
Warrant Agreement to be sent to holders of Redeemable Warrants.

or inconvenient forum. Any such process or summons to be served upon any of 
the Company, the Representative and the Holders (at the option of the party 
bringing such action, proceeding or claim) may be served by transmitting a 
copy thereof, by registered or certified mail, return receipt requested, 
postage prepaid, addressed to it at the address set forth in Section 14

                               WARRANT CERTIFICATE

    This Warrant Certificate certifies that ____________________________, or 
registered assigns, is the registered holder of ______________ Warrants to 
purchase initially, at any time from _______________, 1999 until 5:30 p.m. New 
York time on _______________, 2003 ("Expiration Date"), up to _______________ 
fully paid and non-assessable shares of common stock, $0.01 par value ("Common 
Stock"), of PROSPECT MEDICAL HOLDINGS, INC., a Delaware corporation (the 
"Company"), and Redeemable Warrants of the Company (one Redeemable Warrant 
entitling the owner to purchase one fully paid and non-assessable share of 
Common Stock) at the initial exercise price, subject to adjustment in certain 
events (the "Exercise Price"), of $______ per share of Common Stock and $______ 
per Redeemable Warrant, upon surrender of this Warrant Certificate and payment 
of the Exercise Price at an office or agency of the Company, but subject to the 
conditions set forth herein and in the Representative's Warrant Agreement dated 
as of ________________, 1998 between the Company and SECURITY CAPITAL TRADING, 
INC. (the "Warrant Agreement"). Payment of the Exercise Price shall be made by 
certified or official bank check in New York Clearing House funds payable to 
the order of the Company or by surrender of this Warrant Certificate, as 
provided in Section 3 of the Warrant Agreement.

    No Warrant may be exercised after 5:30 p.m., New York time, on the 
Expiration Date, at which time all Warrants evidenced hereby, unless 
exercised prior thereto, shall thereafter be void. 


                                     A-1

<PAGE>

    The Warrants evidenced by this Warrant Certificate are part of a duly 
authorized issue of Warrants issued pursuant to the Warrant Agreement, which 
Warrant Agreement is hereby incorporated by reference in and made a part of 
this instrument and is hereby referred to for a description of the rights, 
limitation of rights, obligations, duties and immunities thereunder of the 
Company and the holders (the words "holders" or "holder" meaning the 
registered holders or registered holder) of the Warrants. 

    The Warrant Agreement provides that upon the occurrence of certain events 
the Exercise Price and the type and/or number of the Company's securities 
issuable thereupon may, subject to certain conditions, be adjusted.  In such 
event, the Company will, at the request of the holder, issue a new Warrant 
Certificate evidencing the adjustment in the Exercise Price and the number 
and/or type of securities issuable upon the exercise of the Warrants; 
provided, however, that the failure of the Company to issue such new Warrant 
Certificates shall not in any way change, alter, or otherwise impair, the 
rights of the holder as set forth in the Warrant Agreement. 

    Upon due presentment for registration of transfer of this Warrant 
Certificate at the principal office of the Company, a new Warrant Certificate 
or Warrant Certificates of like tenor and evidencing in the aggregate a like 
number of Warrants shall be issued to the transferee(s) in exchange for this 
Warrant Certificate, subject to the limitations provided herein and in the 
Warrant Agreement, without any charge except for any tax or other 
governmental charge imposed in connection with such transfer. 

    Upon the exercise of less than all of the Warrants evidenced by this 
Certificate, the Company shall forthwith issue to the holder hereof a new 
Warrant Certificate representing such number of unexercised Warrants. 

    The Company may deem and treat the registered holder(s) hereof as the 
absolute owner(s) of this Warrant Certificate (notwithstanding any notation 
of ownership or other writing hereon made by anyone), for the purpose of any 
exercise hereof, and of any distribution to the holder(s) hereof, and for all 
other purposes, and the Company shall not be affected by any notice to the 
contrary.


                                      A-2

<PAGE>

    All terms used in this Warrant Certificate which are defined in the 
Warrant Agreement shall have the meanings assigned to them in the Warrant 
Agreement. 

    IN WITNESS WHEREOF, the Company has caused this Warrant Certificate to be 
duly executed under its corporate seal.

     NOW, THEREFORE, in consideration of the mutual covenants and conditions
hereinafter set forth and in exchange for good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties agree as
follows:

                                          2
<PAGE>

                                      AGREEMENT

    1.   PREMISES.

         Pursuant to the Master Lease specified below, Manager shall provide
adequate GROUP administrative office space at the addresses described therein
(the "Premises") and facilities for the operation of the Practice with leasehold
improvements, auxiliary services and utilities in order that GROUP may
effectively perform its functions and duties.

         In consideration of the sums to be paid to Manager under the terms of
this Agreement, Manager hereby leases to GROUP during the term of this Agreement
the facilities and leasehold improvements at the Premises and the furniture,
fixtures and equipment (the "FF&E") listed on Exhibit "B" attached hereto and
incorporated herein by this reference, under the following terms and conditions:

         1.1.     Manager is the lessee under certain leases for the Premises
(hereinafter collectively referred to as the "Master Lease") copies of which are
attached hereto as Exhibit "A" and incorporated herein by this reference.  GROUP
hereby acknowledges that the Premises described in the Master Lease are suitable
for the administrative office of the Practice.  Based and contingent upon
GROUP's promise to timely pay all amounts due under this Agreement, Manager
hereby agrees to sublease the leased Premises to GROUP upon the following terms
and conditions:

                  1.1.1.   This sublease between Manager and GROUP of the
Premises shall be subject to all of the terms and conditions of the Master
Lease.  In the event of the termination of Manager's interest as lessee under
the Master Lease for any reason, then the sublease created hereby shall
simultaneously terminate unless GROUP is willing to assume the obligations under
the Master Lease and the Lessor consents thereto.

                  1.1.2.   All of the terms and conditions contained in the
Master Lease are incorporated herein as terms and conditions of the sublease
(with each reference therein to "Lessor" and "Lessee," to be deemed to refer to
Manager and GROUP, respectively) and, along with the provisions of this Section
1.1 and Exhibit "A," shall be the complete terms and conditions of the sublease
created hereby.

                  1.1.3.   Notwithstanding the foregoing, as between Manager and
GROUP, Manager shall remain responsible for meeting the financial obligations of
"Lessee" under the Master Lease, and GROUP shall have no monetary obligation in
that regard.  In addition, as between Manager and GROUP, Manager shall retain
all rights to exercise any options to purchase the Premises, or other similar
rights of ownership or possession, which may be granted under the Master Lease,
and GROUP shall have no rights in that regard.

                  1.1.4.   In the event this Agreement is terminated according
to its terms, this sublease shall also terminate automatically.


                                          3
<PAGE>

                  1.1.5.   If the Master Lease contains an option to renew the
term thereof, Manager shall notify GROUP, at least thirty (30) days prior to the
expiration of the time for exercising such option, of Manager's intention to
renew or not to renew such term.  If Manager determines not to renew such term,
Manager shall, at GROUP's option and upon the consent of the Landlord in
accordance with the terms of the Master Lease, assign the Master Lease to GROUP,
including Manager's right to renew the term thereof.

    2.   PROVISION OF FURNITURE, FURNISHINGS AND EQUIPMENT ("FF&E").

         Manager hereby provides to GROUP, and GROUP hereby leases from Manager,

following conditions:

         2.1.     Title to all of the FF&E shall remain in Manager at all times,
and upon the termination of this Management Services Agreement, GROUP shall
immediately surrender the FF&E to Manager in as good condition as of the date
hereof, normal wear and tear excepted.  Alternatively, GROUP, in its sole
discretion, shall have the option to purchase any or all of the FF&E upon
termination hereof.  GROUP shall exercise such option, if at all, by giving
Manager written notice of same (the "Notice") within twenty (20) days of the
effective date of termination hereof.  Upon exercise of such option, Manager
shall convey to GROUP within thirty (30) days of the effective date of
termination hereof, all of the FF&E identified in the Notice, together with (i)
any manufacturer's warranties that Manager has received in connection with such
FF&E and (ii) a bill of sale or such other instrument of conveyance as is
reasonably necessary to accomplish said purchase; and GROUP shall simultaneously
convey to Manager the purchase price for said FF&E.  The purchase price shall be
paid all in cash, and shall equal the fair market value of the FF&E.

         2.2.     Manager shall be responsible for all repairs and maintenance
of the FF&E other than damage caused by negligence or willful misuse by GROUP;
provided, however, GROUP shall employ reasonable efforts to prevent damage to
and excessive wear of the FF&E, and shall promptly notify Manager of any needed
repairs thereto.

         2.3.     Manager shall be responsible for all property taxes and other
assessments relating to or arising out of ownership or use of the FF&E that
accrue on and after the date hereof.

         2.4.     Manager shall provide and maintain, at its expense, such
additional or replacement FF&E as the Practice reasonably requires from time to
time, as determined by Manager in its sole discretion, in consultation with
GROUP.  Such additional or replacement FF&E shall be subject to all of the terms
of Section 2.1 above.

         2.5.     GROUP may provide additional equipment at the Practice ("GROUP
Equipment") at its sole cost and expense.  GROUP shall be responsible for all
repairs, maintenance and replacement of, as well as all property taxes and other
assessments relating to or arising out of ownership or use of, such additional

God, or any other event which is beyond the reasonable control of Manager or
which was not reasonably foreseeable by Manager.

    4.   RESPONSIBILITIES OF GROUP.

         4.1.     GROUP covenants and agrees that, at all times during the term

appointment of committee members including but not limited to the Utilization
Review and Quality Assurance Committees.  In addition, GROUP agrees to appoint a
Medical Director.  GROUP shall be solely responsible for payment of any and all
compensation, payroll taxes, fringe benefits, disability insurance, workers'
compensation insurance and any other benefits of all such individuals.

Providers unless such Participating Providers have: (i) current unrestricted

Enforcement Agency ("DEA") numbers.  In addition, where GROUP contracts with
individual physicians, such physicians shall have medical staff membership at
the hospitals required by Participating Plans and where GROUP contracts with
licensed clinics and medical groups, at least one primary care physician
practicing at each clinic or medical group shall have medical staff membership
at the hospitals required by Participating Plans.  GROUP further agrees to
establish procedures to ensure that Participating Providers meet these
requirements on an ongoing basis.  Manager shall reasonably cooperate with and
assist GROUP to meet its obligations under this Section 4.2; provided however,
that GROUP acknowledges and agrees that it shall retain ultimate responsibility
for meeting such obligations.

for making all required reports to the Medical Board of California under Section
805 of the California Business and Professions Code and the National
Practitioner Data Bank.

         4.4.     GROUP shall, at its sole cost and expense, procure and
maintain at all times during the term of this Agreement comprehensive general
and professional liability insurance covering all activities of GROUP directly
or indirectly relating to GROUP, each policy in a minimum amount of
$1,000,000.00 per occurrence and $3,000,000.00 in the aggregate.  The
aforedescribed comprehensive general and professional liability insurance shall
be issued by a company or companies authorized to do business in California with
a financial rating of at least A:12 or better in "Best's Key Rating Guide" or
its equivalent.  In the event GROUP procures a "claims made" policy as
distinguished from an "occurrence" policy, GROUP shall procure and maintain at
its sole cost and expense, prior to termination of such insurance, "tail"
coverage to continue and extend coverage complying with this Agreement after the
end of the "claims made" policy.  Upon reasonable request from Manager, GROUP
shall cause to be issued to Manager proper certificates of insurance, evidencing
that the foregoing provisions of this Agreement have been complied with, and
said certificates shall provide that prior to any cancellation or change in the
underlying insurance during the policy period, the insurance carrier shall first
give thirty (30) calendar days written notice to Manager.

         4.5.     Subject to the terms and conditions of Sections 3.1.6.3 and

limited to, the payment of all salaries, benefits, medical malpractice
insurance, employ or contract with such physicians as shall be reasonably
necessary for the conduct of the Practice.

maintain professional liability insurance with minimum coverage amounts of
$1,000,000.00 per occurrence and $3,000,000.00 in the aggregate.  GROUP shall
ensure that any Participating Provider who procures insurance required hereunder
on a "claims made" rather than an "occurrences" form will obtain either extended
reporting insurance coverage ("tail coverage") with liability limits equal to
those most recently in effect prior to the day of termination of such
Participating Provider's contract with GROUP, or will enter into such other
arrangements as shall reasonably assure the maintenance of coverage for such
Provider, GROUP, and Manager against the risk of loss in respect of professional
services rendered by such provider while this Agreement was in effect and for a
period of not less than seven (7) years after the date of termination of this
Agreement.

to this Agreement are incorporated herein by this reference and all references
herein to "Agreement" shall mean this Agreement together with all such exhibits

this Agreement and each and every provision hereof of which time of performance
is a factor.

                  15.12.1. Subject to the terms of Section 15.12.2, in the event
the parties hereto are unable to resolve any and all disputes in connection with
this Agreement, either party may commence arbitration by sending a written
demand for arbitration to the other party, setting forth the nature of the
matter to be resolved by arbitration.  Except as may be expressly provided to
the contrary herein, the arbitration procedure described in this Section shall
be the sole means of resolving any disputes hereunder.

                  15.12.2. Notwithstanding the foregoing, it is expressly
understood by the parties that the arbitration procedure described in this
Section shall not be applicable to any disputes between the parties as to
matters over which Manager has exclusive decision-making authority pursuant to
the terms hereof, including without limitation, the Manager's exclusive
decision-making authority with respect to the development of guidelines for the
selection, hiring and firing of health care professionals, compensation payable

                  15.12.3. There shall be one arbitrator.  If the parties shall
fail to select a mutually acceptable arbitrator within ten (10) days after the

                  15.12.4. The parties shall share all costs of arbitration.

be applied by the arbitrator.  The parties shall have the rights of discovery as
provided for in Part 4 of the California Code of Civil Procedure and as provided
for in Section 1283.05 of said Code.  The California Code of Evidence shall
apply to testimony and documents submitted to the arbitrator.

                  15.12.6. Arbitration shall take place in Los Angeles,
California unless the parties otherwise agree.  As soon as reasonably
practicable, a hearing with respect to the dispute or matter to be resolved
shall be conducted by the arbitrator.  As soon as reasonably practicable
thereafter, the arbitrator shall arrive at a final decision, which shall be
reduced to writing, signed by the arbitrator and mailed to each of the parties
and their legal counsel.

                  15.12.7. All decisions of the arbitrator shall be final,
binding and conclusive on the parties and shall constitute the only method of
resolving disputes or matters subject to arbitration pursuant to this Agreement.
The arbitrator or a court of appropriate jurisdiction may issue a writ of
execution to enforce the arbitrator's judgment.  Judgment may be entered upon
such a decision in accordance with applicable law in any court having
jurisdiction thereof.

                  15.12.8. Notwithstanding the foregoing, because time is of the
essence of this Agreement, the parties specifically reserve the right to seek a
judicial temporary restraining order, preliminary injunction, or other similar
short term equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or
dissolve such court order.

                  15.12.9. Notwithstanding the foregoing, any and all
arbitration proceedings are conditional upon such proceedings being covered
under the parties' respective risk insurance policies.

         15.13.   ATTORNEYS' FEES.  Should either party institute any action or
procedure to enforce this Agreement or any provision hereof, or for damages by
reason of any alleged breach of this Agreement or of any provision hereof, or
for a declaration of rights hereunder (including, without limitation,
arbitration), the prevailing party in any such action or proceeding shall be
entitled to receive from the other party all costs and expenses, including
without limitation reasonable attorneys' fees, incurred by the prevailing party
in connection with such action or proceeding.

         15.14.   FURTHER ASSURANCES.  The parties shall take such actions and
execute and deliver such further documentation as may reasonably be required in
order to give effect to the transactions contemplated by this Management
Services Agreement and the intentions of the parties hereto.

         15.15.   RIGHTS CUMULATIVE.  The various rights and remedies herein
granted to Manager or GROUP shall be cumulative and in addition to any other
rights Manager or GROUP, respectively, may be entitled to under law.  The
exercise of one or more rights or remedies shall


                                          23
<PAGE>

not impair the right of Manager or GROUP to exercise any other right or remedy,

     C.   Pursuant to the terms of a proposed Agreement and Plan of 
Reorganization, Med-Search Acquisition Corporation, a Delaware corporation 
and a wholly owned subsidiary of Med-Search, Inc., a Delaware corporation, 
("Med-Search") is intended to merge with and into Buyer (the "Merger").

     D.   Effective as of the Closing of the Merger, Seller desires to grant to

shall mean all of Seller's and Shareholder right, title, interest and estate in
and to all the assets of every kind and description used in or pertaining to the
Practice, including but not limited to the assets set forth on Exhibit A, not
including any assets transferred to Seller pursuant to the terms of the Asset
Transfer Agreement.  When used in this Agreement, the term "Stock" shall mean
all of Shareholder's right, title, interest and estate in and to all of the
issued and outstanding stock in Seller, including any rights to any additional
stock, preemptive rights, warrants, and the like, as set forth on Exhibit B.

     E.   Shareholder, Seller and Buyer desire to enter into this Agreement to
incorporate within the terms of one agreement all of the amendments previously
made and to be made as of the date of execution hereof to an Assignable Option
Agreement made as of June 5, 1996 (the "Original Agreement").

     NOW, THEREFORE, in consideration of the foregoing promises and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged by the parties, Seller, Shareholder, and Buyer agree as follows:

<PAGE>

1.   GRANT OF OPTION.

     1.1  Seller hereby grants to Buyer an assignable option to purchase all or
any part of the Assets (the "Assets Option"), on the terms and subject to the
conditions set forth in this Agreement.

     1.2   Seller and Shareholder hereby grant to Buyer the assignable right to
designate a Successor Physician or Successor Physicians, which person or persons
must be duly licensed physicians in the State of California or otherwise
permitted by law to be a shareholder in a professional corporation, to purchase
all or part of the Stock (the "Stock Option"), on the terms and subject to the
conditions set forth herein.  In its sole discretion, Buyer may designate the
amount of Stock which is to be purchased.  The Assets Option and the Stock
Option are collectively referred to herein as the "Option."

     1.3  Seller and Shareholder represent and warrant that as of the day and
year first above written and during the term of this Agreement, Exhibits A and B
are true and complete listings of the Assets and Stock, respectively, as revised
from time to time pursuant to this Agreement.

     1.4  Except as set forth in the Amended and Restated Credit Succession
Agreement, dated as of July 14, 1997, by and among Prospect Medical Holdings,
Inc., a Delaware corporation, Seller, Shareholder, Buyer, Santa Ana/Tustin
Physicians Group, Inc., a California professional corporation, and Imperial
Bank, a California banking corporation ("Imperial"), as amended (the "Credit
Succession Agreement"), Seller shall not recognize any share transfer or other
action not in compliance with the terms of this Agreement.

2.   TERM OF AGREEMENT.  The term of this Agreement commences as of the day and
year first above written and continues for thirty (30) years ("Term").  So long
as the term of the Management Services Agreement, made and entered into as of
June 4, 1996, as amended,  by and between Buyer and Seller (the "Management
Services Agreement"), is automatically extended pursuant thereto, the term of
this Agreement shall be automatically extended for additional coextensive terms
of ten (10) years each.  In the event the Management Services Agreement is
terminated pursuant to its terms, this Agreement shall terminate upon the
effective date of termination of said Management Services Agreement.

3.   OPTION PRICE.  The purchase price for the Option (the "Option Price") is
One Hundred Dollars ($100) and Seller and Shareholder acknowledge receipt of
such payment.

4.   EXERCISE OF OPTION.

     4.1  During the Term of this Agreement, Buyer may elect to exercise the
Option at any time.  In the event of an election by Buyer to exercise the
Option, Buyer may exercise either the Assets Option or the Stock Option, or
both, at Buyer's sole discretion.

     4.2  Notwithstanding the provisions of Section 4.1, if the Management
Services Agreement is terminated by either party, for any reason, Buyer's right
to exercise the Option is 

                                       2

<PAGE>

automatically and immediately exercised as of the termination date of the 
Management Services Agreement such that Buyer may exercise either the Assets 
Option or the Stock Option, or both, at such time.

     4.3  To the extent that the Assets Option is exercised by Buyer, Buyer will
send Seller a written notice (the "Assets Exercise Notice") specifying the
Assets to be purchased.  Buyer may exercise the Assets Option as many times as
Buyer elects in its sole discretion.

     4.4  To the extent that the Stock Option is exercised by Buyer, Buyer will
send Seller a written notice (the "Stock Exercise Notice") specifying the Stock
to be purchased.  Buyer may designate the Successor Physician(s) who will
exercise the Stock Option as many times as Buyer elects in its sole discretion.

      4.5 The Assets Option and the Stock Option are independent of each other,
and can be exercised at different times during the Term.

      4.6 Buyer may cancel any Assets Exercise Notice or Stock Exercise Notice
at any time.

      4.7 Seller and Shareholder shall cooperate with Buyer in any due
diligence.

5.   ASSIGNMENT OF THE OPTION.  Buyer may elect to assign either the Assets
Option or the Stock Option or both to any person, by a written assignment,
signed by both Buyer and the assignee, which designates the Assets and/or Stock.
The assignee shall agree as a condition of the assignment to be bound by the
terms of this Agreement.  Thereafter, only the assignee named in the assignment
shall have the right to exercise the applicable Assets Option and/or the Stock
Option as to the designated Assets and/or Stock, and that assignee, rather than
Buyer, shall enter into a purchase agreement upon exercise of the Assets Option
and/or the Stock Option, as applicable.  Written notice of any such assignment
shall be given by Buyer to Seller and Shareholder within a reasonable time
period following execution of any assignment pursuant to this Agreement.  When
the context so requires in this Agreement, the term "Buyer" shall be deemed to
refer to an assignee holding an assignment of an Asset Option or Stock Option,
and the terms "party" and "parties" shall be deemed to include that assignee.

6.   PURCHASE PRICE OF THE ASSETS OR STOCK.

     6.1  PURCHASE PRICE.

     a.   ASSETS PURCHASE PRICE.  The purchase price for the Assets to be 
purchased pursuant to the exercise of the Assets Option shall be $1,000 
("Assets Purchase Price").  The purchase price of any partial purchase of the 
Assets shall be a pro-rata percentage of the full Assets Purchase Price.

     b.   STOCK PURCHASE PRICE.  The purchase price for the Stock to be 
purchased pursuant to the exercise of the Stock Option shall be $1,000 
("Stock Purchase Price").  The purchase price 

                                       3

<PAGE>

of less than all of the issued and outstanding Stock is a pro-rata percentage 
of the full Stock Purchase Price.

     6.2  PAYMENT.  For the Assets, Buyer shall pay Seller the Assets Purchase
Price at Closing in the form of immediately available funds transferred by wire
to an account at a financial institution designated by Seller.  For the Stock,
Buyer shall cause the Successor Physician to pay the Shareholder the Stock
Purchase Price.

     6.3  CLOSING.  The transactions contemplated by this Agreement are to close
forty-five (45) days after the date of either the Assets Exercise Notice or the
Stock Exercise Notice, as the case may be ("Closing"), unless extended by Buyer.

7.   ADDITIONAL OBLIGATIONS OF SELLER.

     9.14 DISPUTE RESOLUTION.  In the event the parties hereto are unable to
resolve any dispute in connection with this Agreement, the parties may mutually
agree to arbitrate as set forth below.

     a.   There shall be one arbitrator.  If the parties shall fail to select a

     b.   The substantive law of the State of California shall be applied by the
arbitrator.

     c.   Arbitration shall take place in Los Angeles, California, unless Seller

reduced to writing, signed by the arbitrator and mailed to each of the parties
and their legal counsel.

on the parties and shall constitute the only method of resolving disputes or
matters subject to arbitration pursuant to this Agreement.  The arbitrator or a
court of appropriate jurisdiction may issue a writ of execution to enforce the
arbitrator's judgment.  Judgment may be entered upon such a decision in
accordance with applicable law in any court having jurisdiction thereof.

     e.   Notwithstanding the foregoing, because time is of the essence of this
Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar short term
equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or
dissolve such court order.

     f.   Notwithstanding the foregoing, any and all arbitration proceedings are
conditional upon such proceedings being covered within the parties' respective

prevailing party in any such action or proceeding shall be entitled to receive
from the other party all costs and expenses, including without limitation
reasonable attorneys' fees, incurred by the prevailing party in connection with
such action or proceeding.

     9.16 FURTHER ASSURANCES.  The parties shall take such actions and execute

give effect to the transactions contemplated by this Agreement and the
intentions of the parties hereto.

     9.17 RIGHTS CUMULATIVE.  The various rights and remedies herein granted to
the respective parties hereto shall be cumulative and in addition to any other
rights any such party may 

                                       8

     THIS INDIVIDUAL NON-COMPETITION AGREEMENT ("Agreement") is made as of this

professional corporation ("Prospect Medical Group") and Gregg DeNicola, M.D.,

                                       RECITALS

     A.   Prospect Medical Group and Prospect Medical Group's Affiliates are in
the business of developing and operating an integrated healthcare delivery
system in the State of California and other areas.  Such system includes primary
care physicians, specialty care physicians, other outpatient and ancillary
services, and management and administrative services. 

     B.   To develop an integrated healthcare delivery system, Prospect Medical
Group previously caused the formation of a management services organization,
Prospect Medical Systems, Inc., a Delaware corporation ("Prospect Medical
Systems"), to provide management and administrative services to Prospect Medical
Group and its other Affiliates.  

     C.   Following formation of Prospect Medical Systems, Prospect Medical
Group and Prospect Medical Systems entered into an Asset Transfer Agreement
providing for the transfer of certain non-professional assets to Prospect
Medical Systems from Prospect Medical Group.

     D.   In connection therewith Prospect Medical Group, Physician and Prospect
Medical Systems previously entered into an Assignable Option Agreement, dated as
of June 5, 1996 (the "Assignable Option Agreement") pursuant to which Prospect
Medical Group granted to Prospect Medical Systems an assignable option to
purchase all of Prospect Medical Group's remaining assets and the right to
designate the purchaser of all or a part of the issued and outstanding stock in
Prospect Medical Group under certain circumstances.  

     E.   Prospect Medical Group and Prospect Medical Systems previously entered
into a Management Services Agreement pursuant to which Prospect Medical Systems
provides management and administrative services to Prospect Medical Group in
return for a management fee which is calculated based upon the revenues derived

shall inure to the benefit of the parties and their respective heirs (as
applicable), legal representatives, and permitted successors and assigns.  No
party may assign this Agreement or the rights, interests or obligations
hereunder; PROVIDED, however, Prospect Medical Group may, (i) assign any or all
of its rights and interests hereunder to one or more of its Affiliates and (ii)
designate one or more of its Affiliates to perform its obligations hereunder (in
any or all of which cases Prospect Medical Group shall remain liable and
responsible for the performance of all of its obligations hereunder). Any
assignment or delegation in contravention of this Section shall be null and
void.

     6.2  COUNTERPARTS.  This Agreement, and any amendments thereto, may be
executed in counterparts, each of which shall constitute an original document,
but which together shall constitute one and the same instrument.

     6.3  HEADINGS.  The section headings contained in this Agreement are
inserted for convenience only and shall not affect in any way the meaning or
interpretation of this Agreement.

     6.4  AMENDMENT.  This Agreement may not be amended except by a writing
executed by all parties.

     6.5  TIME OF ESSENCE.  Time is expressly made of the essence of this
Agreement and each and every provision hereof of which time of performance is a
factor.

personal delivery; twenty-four (24) hours following deposit with a courier for

Mail, registered or certified mail, postage prepaid, return-receipt requested,
addressed to the parties at the following addresses or to such other addresses
as the parties may specify in writing:

                              Attn:  President         

     6.7  GOVERNING LAW.  This Agreement shall be governed by and construed in
accordance with the laws of the State of California.

     6.8  INJUNCTIVE RELIEF.  The parties hereto acknowledge and agree that a 
breach by Physician of this Agreement will cause irreparable damage to 
Prospect Medical Group, the exact 

                                     -4-
<PAGE>

amount of which will cause difficult to ascertain, and that remedies at law 
for any such breach will be inadequate.  Accordingly, Physician agrees that 
if Physician breaches this Agreement, then Prospect Medical Group shall be 
entitled to injunctive relief, and Physician agrees not to assert in any 
proceeding that Prospect Medical Group has an adequate remedy at law.  
Physician shall pay the reasonable fees and expenses, including attorneys 
fees, incurred by Prospect Medical Group or any successor or assign in 
enforcing this Agreement.

     6.9  SEVERABILITY.  If any provision or portion of this Agreement is held
by a court of competent jurisdiction to be invalid or unenforceable, the
remainder of this Agreement will nevertheless continue in full force and effect
and shall not be invalidated or rendered unenforceable or otherwise adversely
affected, unless such invalidity or unenforceability would defeat an essential
business purpose of this Agreement.  Without limiting the generality of the
foregoing, if the provisions of this Agreement shall be deemed to create a
restriction, which is unreasonable as to either duration or geographical area or
both, the parties agree that the provisions of this Agreement shall be enforced
for such duration and in such geographic area as any court of competent
jurisdiction may determine to be reasonable.

     6.10 ATTORNEYS' FEES.  Should either Prospect Medical Group or Physician
institute any action or procedure to enforce this Agreement or any provision
hereof, or for damages by reason of any alleged breach of this Agreement or of
any provision hereof, or for a declaration of rights hereunder (including
without limitation arbitration), the prevailing party in any such action or
proceeding shall be entitled to receive from the other party all costs and
expenses, including without limitation reasonable attorneys' fees, incurred by
the prevailing party in connection with such action or proceeding.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of
the day and year first written above.

          THIS EMPLOYMENT AGREEMENT (this "Agreement") is executed as of the
31st day of July, 1996, by and between Med-Search, Inc., a Delaware corporation
("Employer"), and Gregg DeNicola, M.D. ("Employee").

duties shall include, but not be limited to, the following:

          (a)  General supervision, direction, and control of the business and
the officers of Employer, subject to the control of the Board of Directors;

          (b)  In the absence of the Chairman of the Board, preside at all

Directors or the Bylaws of Employer.

2.   COMPENSATION

     2.1  SALARY.  Employer shall pay Employee the salary of three hundred
thousand dollars ($300,000) per annum.  Employer shall pay Employee in
accordance with Employer's policies for the payment of exempt, salaried

cost of and subject to all state and federal withholding taxes and any other
applicable taxes.

<PAGE>

     2.2  PERFORMANCE CRITERIA.  Employer may determine from time to time to pay
Employee additional compensation/discretionary bonus(es).  Any such
determination shall be made by the Compensation Committee, or similar committee,
if any, of the Board of Directors of Employer or, if there is no such committee,
by the Board of Directors of Employer.

     2.3  BENEFITS.  During the term of this Agreement, Employer shall provide
Employee and his or her beneficiaries with certain employment benefits,
including but not limited to health insurance benefits.  However, Employer's
life insurance company and/or disability insurer may require Employee to

policy to Employee, and Employee shall comply with all such reasonable
requirements.  In addition, Employer may elect to obtain key-man life insurance
coverage on Employee, and Employee agrees to submit to any required examination
therefor.  Employee shall be entitled to participate in Employer's retirement

with the retirement benefits offered to Employer's other employees at the
Practice.

3.   TERM AND TERMINATION OF AGREEMENT

     3.1  CONTRACT TERM.  The initial term of this Agreement shall commence on
the closing of the merger of Employer and Med-Search, Inc., a Delaware
corporation (the "Effective Date"), and shall continue for a period of three (3)
years, subject to earlier termination of this Agreement as provided herein.

     3.2  TERMINATION WITHOUT CAUSE.  No party may terminate this Agreement or
Employee's employment hereunder, without cause.

     3.3  TERMINATION BY EMPLOYER.  Employer may terminate Employee's employment
hereunder at any time for "cause" by giving written notice of termination to the
defaulting party (the "Termination Notice").  In the event such breach is not
cured within thirty (30) days after the giving of the Termination Notice, this
Agreement shall automatically terminate at the election of the Employer thirty

following:

          (a)  Upon material violation by Employee of any provision of this
Agreement.

policies and procedures; or upon inability of Employee to perform duties
required hereunder for a designated period of time in accordance with Employer's
employment policies and procedures.

          (c)  Upon Employee's conviction of a felony or crime of moral
turpitude.

          (d)  Upon the use of alcohol or a controlled substance which
materially impairs the ability of Employee to effectively perform Employee's
duties and obligations under this Agreement.

<PAGE>

     3.4  TERMINATION BY EMPLOYEE.  Employee may terminate his or her employment
hereunder at any time for "cause."  Cause is limited to Employer's breach of its

cause, termination shall be effective immediately upon notification to Employer
by Employee.

     3.5  EFFECT OF TERMINATION.  Upon and after termination of this Agreement,
Employee will be provided full access to copy Employer patient medical records
in the event of a malpractice action or administrative investigation or
proceeding against Employee.

4.   CONFIDENTIALITY/TRADE SECRETS.  Employee acknowledges that his position
with Employer will be one of the highest trust and confidence both by reason of
his position and by reason of his access to and contact with the trade secrets
and confidential and propriety business information of Employer and all of its
Affiliates (as defined below), during the term of this Agreement and thereafter.
Employee covenants and agrees as follows:

     4.1  PROTECTION.  That Employee shall use his best efforts and exercise
utmost diligence to protect and safeguard the trade secrets and confidential and
proprietary information of Employer and its "Affiliates" (which term as used in
this Agreement shall include any person, corporation, partnership, general
partner or other entity that directly, or indirectly through one or more
intermediaries, controls or is controlled by or is under common control with
Employer), including, without limitation, their trade secrets, proprietary
information, the identity of their customers and suppliers, their arrangements
with their customers and suppliers, and their technical data, records,
compilations of information, processes, computer software, and specifications
relating to their customers, suppliers, products and services (collectively,
"Confidential Information").

     4.2  NON-DISCLOSURE.  That Employee shall not disclose any Confidential
Information, except as may be required in the course of his employment or as may
be required by law.

     4.3  NON-USAGE.  That Employee shall not use, directly or indirectly, for
his own benefit or for the benefit of another, any Confidential Information.

     The covenants contained in this Section 4 shall not be applicable to any
information which is in the public domain other than as a result of action by
Employee or which Employee can establish was obtained from sources other than
Employer or any of its Affiliates, who are not under a duty of nondisclosure.
All Confidential Information and all files, records, documents, drawings,
specifications, computer software, memoranda, notes, or other documents relating
thereto or otherwise relating to the business of Employer and its Affiliates,
whether prepared by Employee or otherwise coming into his possession, shall be
the exclusive property of Employer (and/or its Affiliates, as applicable) and
shall be delivered to Employer or its Affiliates as appropriate and not retained
by (nor any copies thereof retained by) Employee upon termination of his
employment for any reason whatsoever.


                                         -3-
<PAGE>

5.   NON-COMPETITION.  Employee covenants and agrees that:

     5.1  NON-COMPETITION.  So long as Employee is receiving any compensation
from Employer pursuant to this Agreement, Employee shall not, without the prior
written consent of Employer, directly or indirectly, as an employee, employer,
agent, principal, proprietor, partner, shareholder, consultant, director, or
corporate officer, engage in any business or render any services to any business
that is in direct competition with the business of Employer, any of its
affiliates or any individual, corporation, firm, partnership, association or
other entity to which Employer or any of its affiliates provides services under
an agreement with such individual, corporation, firm, partnership, association
or other entity within a fifteen (15) mile radius area of each facility of
Employer or any of its affiliates now existing or hereafter established.  For
reference, the current facilities of Employer and its affiliates are listed in
Attachment A hereto.

     5.2  MODIFICATION.  If the scope of any restrictions contained in Section 5
hereof are too broad to permit enforcement of such restrictions to their full
extent, then such restrictions shall be enforced to the maximum extent permitted
by law, and Employee hereby consents and agrees that such scope may be modified
accordingly in any proceeding brought to enforce such restrictions.

6.   REMEDIES FOR BREACH OF COVENANTS OF EMPLOYEE.  The covenants set forth in
Sections 4 and 5 of this Agreement shall continue to be binding upon Employee
notwithstanding the termination of his employment with Employer for any reason
whatsoever.  Such covenants shall be deemed and construed as separate agreements
independent of any other provision of this Agreement.  The existence of any
claim or cause of action by Employee against Employer or any of its Affiliates,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by Employer or any of its Affiliates of any or all of
such covenants.  It is expressly agreed that the remedy at law for the breach of
any such covenant is inadequate and that temporary and permanent injunctive
relief shall be available to prevent the breach or any threatened breach
thereof, without the necessity of proof of actual damages and without the
necessity of posting a bond, cash or otherwise.  In this connection, Employee
agrees not to assert any defense that monetary damages would be sufficient.

7.   ARBITRATION.  The parties firmly desire to resolve all disputes arising
hereunder without resort to litigation in order to protect their respective
business reputations and the confidential nature of certain aspects of their
relationship.  Accordingly, any controversy or claim arising out of or relating
to this Agreement, or the breach thereof, shall be settled by arbitration as set
forth below.

     (1)  All disputes which in any manner arise out of or relate to this
Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 7.  Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.


                                         -4-
<PAGE>

     (2)  There shall be one arbitrator.  If the parties shall fail to select a
mutually acceptable arbitrator within ten (10) days after the demand for
arbitration is mailed, then the parties stipulate to arbitration before a single
arbitrator sitting on the Los Angeles, California Judicial Arbitration Mediation
Services (JAMS) panel, and selected in the sole discretion of the JAMS
administrator.

     (3)  The parties shall share all costs of arbitration.  The prevailing
party shall be entitled to reimbursement by the other party of such party's
attorneys' fees and costs and any arbitration fees and expenses incurred in
connection with the arbitration hereunder.

     (4)  The substantive law and the Evidence Code of the State of California
shall be applied by the arbitrator, except that the arbitrator's authority in
awarding damages shall be interpreted under New York law.  THE PARTIES AGREE
THAT THE ARBITRATOR SHALL HAVE NO AUTHORITY TO AWARD PUNITIVE DAMAGES, AND THE
PARTIES HAVE BEEN ADVISED TO SEEK COUNSEL CONCERNING THE POSSIBLE WAIVER BY THE
PARTIES OF CERTAIN RIGHTS OTHERWISE AVAILABLE AS A CONSEQUENCE OF SUCH
AGREEMENT.

     (5)  Arbitration shall take place in Los Angeles, California unless the
parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable thereafter, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

     (6)  All decisions of the arbitrator shall be final, binding and conclusive
on the parties and shall constitute the only method of resolving disputes or
matters subject to arbitration pursuant to this Agreement.  The arbitrator or a
court of appropriate jurisdiction may issue a writ of execution to enforce the
arbitrator's judgment.  Judgment may be entered upon such a decision in
accordance with applicable law in any court having jurisdiction thereof.

     (7)  Notwithstanding the foregoing, because time is of the essence of this
Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar short term
equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or
dissolve such court order.

     (8)  The decision and award of the arbitrator shall be kept confidential by
the parties to the greatest extent possible.  No disclosure of such decision or
award shall be made by the parties except as required by law or as necessary or
appropriate to effect the enforcement thereof.

                                EMPLOYMENT AGREEMENT

      THIS EMPLOYMENT AGREEMENT (this "Agreement") is executed as of the 31st
day of July, 1996, by and between Med-Search, Inc., a Delaware corporation
("Employer"), and Jacob Y. Terner, M.D. ("Employee").

                                  P R E A M B L E

      A.    Employer is a provider of management services to medical practices;
and

      B.    Employer desires to obtain the services of Employee as Chief
Executive Officer of Employer, and Employee desires to be employed by Employer,
upon the terms and conditions hereinafter set forth;

      NOW, THEREFORE, in consideration of the premises and other good and
valuable consideration, the sufficiency of which is hereby acknowledged, the
parties agree as follows:

1.    TERMS AND CONDITIONS OF EMPLOYMENT

      1.1   EMPLOYMENT. Employer hereby employs Employee and Employee hereby
accepts employment as Chief Executive Officer of Employer subject to the terms
and conditions hereinafter set forth.

      1.2   FULL-TIME EMPLOYMENT. Employee agrees to devote his full time and
attention to the performance of his duties as Chief Executive Officer of
Employer. Employee's duties shall include, but not be limited to, the following:

            (a)   General supervision, direction, and control of the business
and the officers of Employer, subject to the control of the Board of Directors;

            (b)   Preside at all meetings of the shareholders and at all
meetings of the Board of Directors; and

            (c)   Such other powers and duties as may be prescribed by the Board
of Directors or the Bylaws of Employer.

2.    COMPENSATION

      2.1   SALARY. Employer shall reimburse Employee for any and all costs,
fees and expenses incurred by Employee in the course of his duties as Chief
Executive Officer. Employee acknowledges that, due to Employer's current
financial condition, Employer does not have sufficient funds to adequately
compensate Employee for his services. Employer and Employee agree to negotiate a
fair and equitable salary to compensate Employee for his services, in accordance
with the policies and procedures established by the Board of Directors, at such
time as Employer's financial condition improves. At that time, Employer shall
pay Employee in accordance with Employer's policies for the payment of exempt,
salaried employees in effect from

<PAGE>

time to time. Salary payments are to be reduced by the cost of and subject to 
all state and federal withholding taxes and any other applicable taxes

      2.2   PERFORMANCE CRITERIA. Employer may determine from time to time to 
pay Employee additional compensation/discretionary bonus(es). Any such 
determination shall be made by the Compensation Committee, or similar 
committee, if any, of the Board of Directors of Employer or, if there is no 
such committee, by the Board of Directors of Employer.

      2.3   BENEFITS. During the term of this Agreement, Employer shall 
provide Employee and his or her beneficiaries with certain employment 
benefits, including but not limited to health insurance benefits. However, 
Employer's life insurance company and/or disability insurer may require 
Employee to satisfactorily pass a physical examination in order to issue a 
life insurance policy to Employee, and Employee shall comply with all such 
reasonable requirements. In addition, Employer may elect to obtain key-man 
life insurance coverage on Employee, and Employee agrees to submit to any 
required examination therefor. Employee shall be entitled to participate in 
Employer's retirement and other benefit plans as offered from time to time at 
a level commensurate with the retirement benefits offered to Employer's other 
employees at the Practice.

3.    TERM AND TERMINATION OF AGREEMENT

      3.1   CONTRACT TERM. The initial term of this Agreement shall commence on
the closing of the merger of Employer and Med-Search, Inc., a Delaware
corporation (the "Effective Date"), and shall continue for a period of three (3)
years, subject to earlier termination of this Agreement as provided herein.

      3.2   TERMINATION WITHOUT CAUSE. No party may terminate this Agreement or
Employee's employment hereunder, without cause.

      3.3   TERMINATION BY EMPLOYER. Employer may terminate Employee's
employment hereunder at any time for "cause" by giving written notice of
termination to the defaulting party (the "Termination Notice"). In the event
such breach is not cured within thirty (30) days after the giving of the
Termination Notice, this Agreement shall automatically terminate at the election
of the Employer thirty (30) days after the giving of the Termination Notice.
Cause includes the following:

            (a)   Upon material violation by Employee of any provision of this
Agreement.

            (b)   Upon total disability of Employee.

            (c)   Upon the use of alcohol or a controlled substance which
materially impairs the ability of Employee to effectively perform Employee's
duties and obligations under this Agreement.

      3.4   TERMINATION BY EMPLOYEE   Employee may terminate his or her
employment hereunder at any time for "cause." Cause is limited to Employer's
breach of its obligation to

                                     -2-
<PAGE>

provide Employee with the Compensation and Benefits required pursuant to this
Agreement. In the event Employee terminates this Agreement for cause,
termination shall be effective immediately upon notification to Employer by
Employee.

      3.5   EFFECT OF TERMINATION. Upon and after termination of this Agreement,
Employee will be provided full access to copy Employer patient medical records
in the event of a malpractice action or administrative investigation or
proceeding against Employee.


4.    CONFIDENTIALITY/TRADE SECRETS. Employee acknowledges that his position 
with Employer will be one of the highest trust and confidence both by reason 
of his position and by reason of his access to and contact with the trade 
secrets and confidential and propriety business information of Employer and 
all of its Affiliates (as defined below), during the term of this Agreement 
and thereafter. Employee covenants and agrees as follows:

      4.1   PROTECTION. That Employee shall use his best efforts and exercise 
utmost diligence to protect and safeguard the trade secrets and confidential 
and proprietary information of Employer and its "Affiliates" (which term as 
used in this Agreement shall include any person, corporation, partnership, 
general partner or other entity that directly, or indirectly through one or 
more intermediaries, controls or is controlled by or is under common control 
with Employer), including, without limitation, their trade secrets, 
proprietary information, the identity of their customers and suppliers, their 
arrangements with their customers and suppliers, and their technical data, 
records, compilations of information, processes, computer software, and 
specifications relating to their customers, suppliers, products and services 
(collectively, "Confidential Information").

      4.2   NON-DISCLOSURE.  That Employee shall not disclose any Confidential
Information, except as may be required in the course of his employment or as may
be required by law.

      4.3   NON-USAGE.  That Employee shall not use, directly or indirectly, for
his own benefit or for the benefit of another, any Confidential Information.

      The covenants contained in this Section 4 shall not be applicable to any
information which is in the public domain other than as a result of action by
Employee or which Employee can establish was obtained from sources other than
Employer or any of its Affiliates, who are not under a duty of nondisclosure.
All Confidential Information and all files, records, documents, drawings,
specifications, computer software, memoranda, notes, or other documents relating
thereto or otherwise relating to the business of Employer and its Affiliates,
whether prepared by Employee or otherwise coming into his possession, shall be
the exclusive property of Employer (and/or its Affiliates, as applicable) and
shall be delivered to Employer or its Affiliates as appropriate and not retained
by (nor any copies thereof retained by) Employee upon termination of his
employment for any reason whatsoever.


                                     -3-
<PAGE>

5.    NON-COMPETITION.  Employee covenants and agrees that:

      5.1  NON-COMPETITION. So long as Employee is receiving any compensation 
from Employer pursuant to this Agreement, Employee shall not, without the 
prior written consent of Employer, directly or indirectly, as an employee, 
employer, agent, principal, proprietor, partner, shareholder, consultant, 
director, or corporate officer, engage in any business or render any services 
to any business that is in direct competition with the business of Employer 
or any of its affiliates within a ten (10) mile radius area of 18200 Yorba 
Linda Boulevard, Suite 409, Yorba Linda, California.

      5.2   MODIFICATION. If the scope of any restrictions contained in Section
5 hereof are too broad to permit enforcement of such restrictions to their full
extent, then such restrictions shall be enforced to the maximum extent permitted
by law, and Employee hereby consents and agrees that such scope may be modified
accordingly in any proceeding brought to enforce such restrictions.

6.    REMEDIES FOR BREACH OF COVENANTS OF EMPLOYEE.  The covenants set forth in
Sections 4 and 5 of this Agreement shall continue to be binding upon Employee
notwithstanding the termination of his employment with Employer for any reason
whatsoever. Such covenants shall be deemed and construed as separate agreements
independent of any other provision of this Agreement. The existence of any claim
or cause of action by Employee against Employer or any of its Affiliates,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by Employer or any of its Affiliates of any or all of
such covenants. It is expressly agreed that the remedy at law for the breach of
any such covenant is inadequate and that temporary and permanent injunctive
relief shall be available to prevent the breach or any threatened breach
thereof, without the necessity of proof of actual damages and without the
necessity of posting a bond, cash or otherwise. In this connection, Employee
agrees not to assert any defense that monetary damages would be sufficient.

7.     ARBITRATION  The parties firmly desire to resolve all disputes arising
hereunder without resort to litigation in order to protect their respective
business reputations and the confidential nature of certain aspects of their
relationship. Accordingly, any controversy or claim arising out of or relating
to this Agreement, or the breach thereof, shall be settled by arbitration as
set forth below.

      (1)   All disputes which in any manner arise out of or relate to this
Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 7. Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

      (2)   There shall be one arbitrator. If the parties shall fail to select a
mutually acceptable arbitrator within ten (10) days after the demand for
arbitration is mailed, then the parties stipulate to arbitration before a single
arbitrator sitting on the Los Angeles, California Judicial Arbitration Mediation
Services (JAMS) panel, and selected in the sole discretion of the JAMS
administrator. 

                                     -4-
<PAGE>

      (3)   The parties shall share all costs of arbitration. The prevailing
party shall be entitled to reimbursement by the other party of such party's
attorneys' fees and costs and any arbitration fees and expenses incurred in
connection with the arbitration hereunder.

      (4)   The substantive law and the Evidence Code of the State of
California shall be applied by the arbitrator, except that the arbitrator's
authority in awarding damages shall be interpreted under New York Law. THE
PARTIES AGREE THAT THE ARBITRATOR SHALL HAVE NO AUTHORITY TO AWARD PUNITIVE
DAMAGES, AND THE PARTIES HAVE BEEN ADVISED TO SEEK COUNSEL CONCERNING THE
POSSIBLE WAIVER BY THE PARTIES OF CERTAIN RIGHTS OTHERWISE AVAILABLE AS A
CONSEQUENCE OF SUCH AGREEMENT.

      (5)   Arbitration shall take place in Los Angeles, California unless the
parties otherwise agree. As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator. As soon as reasonably practicable thereafter, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

      (6)   All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement. The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrator's judgment. Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

      (7)   Notwithstanding the foregoing, because time is of the essence of
this Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar short term
equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or
dissolve such court order.

      (8)   The decision and award of the arbitrator shall be kept confidential
by the parties to the greatest extent possible. No disclosure of such decision
or award shall be made by the parties except as required by law or as necessary
or appropriate to effect the enforcement thereof.

8.    MISCELLANEOUS.

      8.1   NOTICES. Any notice, demand, or communication required, permitted
or desired to be given hereunder shall be deemed effectively given when
personally delivered or mailed by prepaid certified mail, return receipt
requested, addressed as follows:

formation or acquisition of other medical groups or independent practice
associations and the preceding and subsequent negotiations with such entities,

reasonable evidence thereof accompanied by a Certificate in the form of 
Exhibit D, attached hereto, certifying that such Reimbursable Expenses have 
been incurred or advanced by Terner, his assigns and/or designees.

Expenses.

     4. COVENANTS OF THE CORPORATION.  The Corporation covenants and agrees as
follows:

California, New York or such jurisdictions as Terner may request, and to make
such applications, file such documents, and furnish such information as may
reasonably be required for such purposes.

          (b)  AMENDMENTS.  If at any time before the Expiration Date, any event
occurs as a result of which the Offering Memorandum, as then amended or
supplemented, would include any untrue statement of a material fact or omit to
state a material fact necessary to make the statements therein not misleading,
or if it is necessary at any time to amend the Offering Memorandum to comply
with the Act, or with any Blue Sky law, the Corporation shall promptly notify
Terner thereof and provide Terner with such information as may be required to
prepare an amendment.

     5. REPRESENTATIONS AND WARRANTIES OF THE CORPORATION.  The Corporation

<PAGE>

untrue statement of a material fact or omit to state any material fact 
required to be stated therein or necessary to make statements therein, in the 
light of the circumstances under which they are made, not misleading; when 
the final Offering Memorandum is distributed and at all times subsequent 
thereto up to and including the Expiration Date: (i) the Offering Memorandum 
and any amendment or supplements thereto will contain all statements which 
are required to be stated therein by the Act and the rules and regulations 
thereunder and will comply in all material respects with the Act and the 
rules and regulations thereunder, and (ii) neither the Offering Memorandum 
nor any amendment or supplement thereto will at any such time include any 
untrue statement of a material fact or omit to state any material fact 
required to be stated therein or necessary to make the statements therein not 
misleading.

          (b)  NO SUBSEQUENT MATERIAL EVENTS.  Subsequent to the respective
dates of which information is given in the Offering Memorandum and prior to the
Expiration Date, except as contemplated in the Offering Memorandum, the
Corporation has not incurred and will not have incurred any material liabilities
or obligations, direct or contingent, or entered into any material transactions
not in the ordinary course of business, and there has not been and will not have
been any material adverse change in the financial position or results of
operation of the Corporation.

and has full power and authority to conduct its business and to enter into this
Agreement.

          (d)  AUTHORIZATION OF AGREEMENT.  This Agreement has been duly
authorized, executed and delivered by the Corporation and constitutes a valid
and binding agreement of the Corporation enforceable in accordance with its
terms; the performance of this Agreement and the consummation of the

     6. COVENANTS OF TERNER.  Terner covenants and agrees with the Corporation
as follows:

          (a)  QUALIFICATIONS OF INVESTORS.  Terner will use best efforts to
independently determine that each person who desires to invest in the
Corporation meets the investor suitability requirements set forth in the
Offering Memorandum, including without limitation that each investor is an
"accredited" investor.  Such efforts shall include an independent verification,
by any reasonable means utilized in the ordinary course of business, of the
income and net worth of each person whose investment commitment is obtained by
Terner.  In recommending to a prospective investor the purchase of Stock, Terner
will:

               (1)  have reasonable grounds to believe, on the basis of
information obtained from the prospective investor concerning his investment
objectives, other investments, financial situation and needs, and any other
information known by Terner, that:

                    (i)  the prospective investor is or will be in a financial
position appropriate to enable him to realize to a significant extent any
benefits described in the Offering Memorandum;

                    (ii)  the prospective investor has a fair market net worth
sufficient to sustain the risks inherent to an investment in the Corporation,
including loss of investment and lack of liquidity; and
          
                    (iii)  investment in the Corporation is otherwise suitable
for the prospective investor; and 

               (2)  maintain documents disclosing the basis upon which the
determination of suitability was reached as to each prospective investor.

     7. INDEMNIFICATION.  The Corporation shall indemnify and hold harmless
Terner and each of Terner's affiliates within the meaning of the Act against any
losses, claims, damages or liabilities, joint or several, including costs and
reasonable attorneys fees incurred in the investigation and defense of such
claims, to which Terner or such controlling person may become subject under the
Act or otherwise, insofar, as such losses, claims, damages or liabilities (or
actions in respect thereof), arise out of or are based upon any untrue statement
or alleged untrue statement of any material fact contained in the Offering
Memorandum, or any amendment or supplement thereto, or arise out of or are based
upon the omission or alleged omission to state therein a material fact required
to be stated therein or necessary to make the statements therein not misleading,
and will reimburse Terner and each such affiliate for any legal or other
expenses 


                                     -5-

reasonably incurred in connection with investigating or defending any such 
loss, claim, damage, liability or action.

     8. NOTICE.  Any notice, payment, demand or communication required or
permitted to be given by any provision of this Agreement shall be deemed to have
been sufficiently given or served for all purposes if delivered personally in

or if sent by registered or certified mail, postage and charges prepaid,

mail, addressed and sent as aforesaid.

     9. CONSTRUCTION.  The parties have each been represented by separate
counsel and have participated jointly in the negotiation and drafting of this
Agreement and in the event of any ambiguity or question of intent or
interpretation, no presumption or burden of proof shall arise favoring or
disfavoring any party by virtue of the authorship of any of the provisions of
this Agreement.

     10. GOVERNING LAW.  This Agreement shall be governed, construed and
enforced in accordance with the internal laws of the State of California.

     11. DISPUTE RESOLUTION.

          (a)  In the event the parties hereto are unable to resolve any dispute
in connection with this Agreement, the parties agree to arbitrate in accordance
with the following.

          (b)  There shall be one arbitrator.  If the parties shall fail to

for arbitration is mailed, the parties stipulate to arbitration before a retired
judge sitting on the Los Angeles Judicial Arbitration Mediation Services (JAMS)

          (c)  The parties shall share all costs of arbitration.  The prevailing
party shall be entitled to reimbursement by the other party(ies) of such
party's(ies') attorney's fees and costs and any arbitration fees and expenses

          (d)  The substantive law of the State of California shall be applied
by the arbitrator to the resolution of the dispute.  The parties shall have the
rights of discovery as provided for in Part 4 of the California Code of Civil

Code of Evidence shall apply to testimony and documents submitted to the
arbitrator.

the parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable thereafter, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

          (f)  All decisions of the arbitrator shall be final, binding and
conclusive on all parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement.  The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrators judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

          (g)  Notwithstanding the foregoing, because time is of the essence of
this Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar short term
equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or
dissolve such court order.

prevailing party in any such action or proceeding shall be entitled to receive
from the other party all costs and expenses, including without limitation
reasonable attorneys' fees, incurred by the prevailing party in connection with
such action or proceeding.

     13. SEVERABILITY.  Should any one or more of the provisions of this
Agreement be determined to be illegal or unenforceable, all other provisions of
this Agreement shall be given effect separately from the provision or provisions
determined to be illegal or unenforceable and shall not be affected thereby.

     14. PARTIES IN INTEREST.  Terner's assigns and designees are expressly made
third party beneficiaries of this Agreement.  Except as specifically set forth

<PAGE>

                                     AGREEMENT

     This AGREEMENT ("Agreement") is made and entered into as of July 31, 1996,
by and among Jacob Y. Terner, M.D. ("Terner"), Barbara Noble ("Noble"), both
individually and as representative ("Representative") of Joseph W. Noble, M.D.,
deceased ("Dr. Noble"), and the Noble 1992 Family Trust (the "Trust") of which
Noble is the sole Trustee.

                                      RECITALS

     This Agreement is made with reference to the following facts and
circumstances:

     A.   Noble controls disposition of Suncrest Medical Group, Inc., a
California professional corporation ("Suncrest") of which Dr. Noble was the sole
shareholder;

     B.   Noble is the sole owner of 1.5 million (1,500,000) shares and the
Trust is the sole owner of 3.5 million (3,500,000) shares for a total of five
million (5,000,000) shares ("Pre-Split Shares") of the Common Stock of
Med-Search, Inc., a Delaware corporation ("Company");

     C.   Pursuant to the terms of that certain Agreement and Plan of
Reorganization, of even date herewith, a wholly owned subsidiary of the Company
is merging with and into Prospect Medical Systems, Inc. (the "Merger"). At the
closing of the Merger, Terner will be appointed Chairman of the Board of
Directors and Chief Executive Officer of the Company;

     D.   Concurrent with the Merger, Prospect Medical Group, Inc., a California
professional corporation ("Prospect Medical Group"), is purchasing certain of
the assets of Suncrest, pursuant to that certain Agreement for the Purchase and
Sale of Assets of even date herewith ("Asset Purchase Agreement");

     E.   Prospect Medical Group has previously entered into a Management
Services Agreement, dated June 4, 1996, with Prospect Medical Systems, Inc., a
Delaware corporation ("Prospect Medical Systems") pursuant to which Prospect
Medical Systems has agreed to provide certain management and administrative
services to Prospect Medical Group. As consideration for providing such
services, Prospect Medical Group pays a management fee to Prospect Medical
Systems in an amount which is calculated based upon the revenues generated by
Prospect Medical Group. Following the closing of the Merger, as a result of the
purchase of certain assets of Suncrest by Prospect Medical Group pursuant to the
terms of the Asset Purchase Agreement, Prospect Medical Systems expects that the
revenues generated by Prospect Medical Group will increase with a corresponding
increase in the management fees payable to Prospect Medical Systems. Since
Prospect Medical Systems will be a wholly-owned subsidiary of the Company
following the Merger, the increased management fees payable to Prospect Medical
Systems after the Merger will further increase the Company's revenues.

<PAGE>

     F.   Subsequent to the Merger, the Company intends to engage in a reverse
stock split ("Reverse Stock Split") pursuant to which the Company will issue one
(1) new share ("Post-Split Share") of its Common Stock in exchange for each
forty-four (44) Pre-Split Shares.

     NOW THEREFORE, in consideration of the covenants and conditions contained
herein and for other valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereby agree as follows:

     1.   ASSET PURCHASE AGREEMENT

     Noble, as Representative of Dr. Noble, will take such action as she deems
necessary or advisable to cause Suncrest to consummate the transactions
contemplated by the Asset Purchase Agreement.

     2.   STOCK PRICE GUARANTY AND ISSUANCE OF ADDITIONAL SHARES

          2.1  STOCK PRICE GUARANTY. In the event the Value, as defined herein,
of the Post-Split Shares is less than one dollar and seventy five cents ($1.75)
per share as of a date ("Calculation Date") thirty (30) months following the
date of the closing of the Merger, Terner will pay to Noble and the Trust,
respectively, the difference between one dollar and seventy five cents ($1.75)
per share and the Value of the Post-Split Shares then held by Noble and the
Trust, respectively, and resulting from the Pre-Split Shares; provided, however,
that if, at any time during such thirty (30) month period the closing bid price
of the Company's stock equals or exceeds one dollar and seventy five cents
($1.75) per share for twenty (20) consecutive trading days, Terner's obligation
to pay such difference will terminate. As used in this Section 2. 1, the
term "Value" shall mean the average closing bid price of the Post-Split Shares
for the twenty (20) consecutive trading days preceding the Calculation Date.

          2.2  ISSUANCE OF ADDITIONAL SHARES. Within sixty (60) days following
the later of the Reverse Stock Split or the Merger, Terner will use his best
efforts to cause the Company to issue to Noble an additional fifty thousand
(50,000) Post-Split Shares. These additional 50,000 Post-Split Shares constitute
additional inducement to Noble to consummate the transactions contemplated by
the Asset Purchase Agreement which transactions are expected to increase the
Company's revenues as recited above. The Stock Price Guaranty set forth in
Section 2.1 shall not apply to the Post-Split Shares issued to Noble pursuant to
this Section 2.2.

     3.   REPRESENTATIONS, WARRANTIES AND COVENANTS OF NOBLE

     Noble, individually, as Representative of Dr. Noble and on behalf of the
Trust, represents and warrants to Terner that the statements in this Section 3
are correct and complete as of the Closing Date, as defined in the Asset
Purchase Agreement (as though made then and as though the Closing Date were
substituted for the date of this Agreement throughout this Section 3).

          3.1  OWNERSHIP OF SHARES. Noble is the sole owner of 1,500,000
Pre-Split Shares. The Trust is the sole owner of 3,500,000 Pre-Split Shares.

                                     -2-
<PAGE>

          3.2  SOLE TRUSTEE. Noble is the sole Trustee of the Trust.

          3.3  SOLE REPRESENTATIVE.  Noble is the sole Representative of Dr.
Noble for purposes of Section 13407 of the California Corporations Code.

          3.4  AUTHORIZATION. Noble, individually, as Representative of Dr.
Noble and as Trustee of the Trust, has the power and authority to enter into

action on the part of Noble, both individually and as Representative of Dr.
Noble, and the Trust necessary for the authorization, execution, delivery and
performance of this Agreement and the consummation of the transactions
contemplated hereby has been or will be taken prior to the Closing Date, and
this Agreement constitutes the legal, valid and binding obligation of Noble,
both individually and as Representative of Dr. Noble, and the Trust, enforceable
in accordance with its terms, except as enforceability may be restricted,
limited or delayed by applicable bankruptcy or other laws affecting creditor's
rights generally and except as enforceability is subject to general principles
of equity.

          3.5  NO CONSENT REQUIRED.  Neither the execution of this Agreement by
Noble, either individually, as Representative of Dr. Noble or as Trustee of the
Trust, nor the performance by Noble, either individually, as Representative of
Dr. Noble or as Trustee of the Trust, of her obligations under this Agreement,
requires the consent of any third party, which has not been obtained and
delivered to Terner prior to the Closing Date.

          3.6  NO VIOLATION OF OTHER AGREEMENTS. Neither this Agreement nor any
of the transactions contemplated hereunder violates or shall violate any lease,
contract, document, understanding, agreement or instrument to which Noble,
either individually or as Representative of Dr. Noble, or the Trust is a party
or by which either may be bound.

          3.7  NO DEFAULT.  Neither Noble, either individually or as
Representative of Dr. Noble, nor the Trust is in default under the terms of any
lease, contract, document, understanding, agreement or instrument pertaining to
or affecting the transactions contemplated hereunder, nor has any event occurred
that shall constitute a default by Noble, either individually or as
Representative of Dr. Noble, or the Trust under any of the same following the
passage of time or consummation of any of the transactions contemplated
hereunder, nor has Noble, either individually or as Representative of Dr. Noble,
or the Trust received any notice of any default under any of the same. No
acceleration or other right to accelerate, terminate, modify, cancel, create a
security interest or otherwise change any existing arrangement will be created
as a result of the consummation of any of the transactions contemplated
hereunder.

          3.8  NO LITIGATION. Except as set forth in Schedule 3.8, there is no
pending litigation or, to the best knowledge of Noble, individually, as
Representative of Dr. Noble and as Trustee of the Trust, threatened litigation,
unasserted claim, or governmental investigation, relating to the Pre-Split
Shares.

          3.9  NO VIOLATION OF LAWS.  To the best knowledge of Noble,
individually, as Representative of Dr. Noble and as Trustee of the Trust,
neither Noble, either individually or as


                                     -3-
<PAGE>

Representative of Dr. Noble, nor the Trust is in violation of any law, rule, 
regulation or administrative or judicial order pertaining to the Pre-Split 
Shares, and, to the best knowledge of Noble, individually, as a 
Representative of Dr. Noble and as Trustee of the Trust, there is no law, 
rule, regulation or administrative or judicial order that any of the 
transactions contemplated by this Agreement would violate.

          3.10 NO BANKRUPTCY PROCEEDINGS. Except as set forth in Schedule 3.10,
neither Noble, either individually or as Representative of Dr. Noble, nor the
Trust has (i) made a general assignment for the benefit of creditors, (ii) filed
any voluntary petition in bankruptcy or suffered the filing of an involuntary
petition by her or its creditors, (iii) suffered the appointment of a receiver
to take possession of all or substantially all of her or its assets, (iv)
suffered the attachment or other judicial seizure of all or substantially all,
of her or its assets, (v) admitted in writing her or its inability to pay her or
its debts as they come due, or (vi) made an offer of settlement, extension or
compromise to her or its creditors generally.
     
          3.11 NO UNTRUE STATEMENTS. To the best knowledge of Noble,

Agreement, (ii) there are no undisclosed liabilities of any nature whatsoever in
connection with the Pre-Split Shares, (iii) neither Noble, either individually

nor as Trustee of the Trust, knows of any facts and has not misrepresented any
facts concerning her, either individually or as Representative of Dr. Noble, or
the Trust's ability, financial or otherwise, to consummate the transactions
contemplated by this Agreement or that would otherwise materially adversely
affect Terner's decision to consummate the transactions contemplated by this
Agreement.

          7.11 FEES AND EXPENSES. Except as otherwise explicitly set forth in a
writing signed by the parties, each party shall bear its own expenses including,
without limitation, attorneys' and accountants' fees in connection with the

judge sitting on the Los Angeles Judicial Arbitration Mediation Services (JAMS)
panel.

               (c)  The parties shall share all costs of arbitration. The

               (d)  The substantive law of the State of California shall be
applied by the arbitrator to the resolution of the dispute. The parties shall
have the rights of discovery as provided for in Part 4 of the California Code of
Civil Procedure and as provided for in Section 1283.05 of said Code. The
California Code of Evidence shall apply to testimony and documents submitted to
the arbitrator.

               (e)  Arbitration shall take place in Los Angeles, California,
unless the parties otherwise agree.  As soon as reasonably practicable, a
hearing with respect to the dispute or matter to be resolved shall be conducted
by the arbitrator. As soon as reasonably practicable thereafter, the arbitrator
shall arrive at a final decision, which shall be reduced to writing, signed
by the arbitrator and mailed to each of the parties and their legal counsel.

               (f)  All decisions of the arbitrator shall be final, binding and
conclusive on all parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement. The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrators judgment. Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

               (g)  Notwithstanding the foregoing, because time is of the
essence of this Agreement, the parties specifically reserve the right to seek a
judicial temporary restraining order, preliminary injunction, or other similar
short term equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or
dissolve such court order.

given by a Responsible Officer of Borrower, followed by a Notice of Borrowing,

11:00 a.m., California time, on the day on which such Borrowing is to be made,
and such notice shall state the amount thereof (subject to the limitations set

accordance therewith.

                 (c)     Bank shall not incur any liability to Borrower in

                 (d)     So long as all of the conditions for a Borrowing set

available to Borrower on the applicable Borrowing date by transferring same day

disbursement instructions given by Borrower


                                          18

to Bank, in form and substance satisfactory to Bank and otherwise consistent
with Section 6.1.

          2.5    INTEREST RATES; PAYMENTS OF INTEREST.

                 (a)     INTEREST RATE.  The unpaid principal balance of all
Loans shall bear interest at the Lending Rate.

                 (b)     DEFAULT RATE.  If any payment of principal or interest
on the Loans shall not be paid when due (whether at the stated maturity, by
acceleration or otherwise), in addition to and not in substitution of any of
Bank's other rights and remedies with respect to such nonpayment, the entire
unpaid principal balance of the Loans shall bear interest at the Lending Rate
PLUS five hundred (500) basis points until such overdue payment is paid in full.
In addition, interest, Bank Expenses, the Fees, and other amounts due hereunder
not paid when due shall bear interest at the Lending Rate PLUS five hundred
(500) basis points until such overdue payment is paid in full.

                 (c)     COMPUTATION OF INTEREST.  All computations of interest
shall be calculated on the basis of a year of three hundred sixty (360) days for
the actual days elapsed.  In the event that the Prime Rate announced is, from
time to time, changed, adjustment in the rate of interest payable hereunder on
the Loans shall be made as of 12:01 a.m. (California time) on the effective date
of the change in the Prime Rate.  Interest shall accrue from the Closing Date to
the date of repayment of the Loans in accordance with the provisions of this
Agreement.

                 (d)     MAXIMUM INTEREST RATE.  In no event shall the interest
rate and other charges hereunder exceed the highest rate permissible under any
law which a court of competent jurisdiction shall, in a final determination,
deem applicable hereto.  In the event that such a court determines that Bank has
received interest and other charges hereunder in excess of the highest rate
applicable hereto, such excess shall be deemed received on account of, and shall
automatically be applied to reduce, the Obligations, other than interest, in the
inverse order of maturity, and the provisions hereof shall be deemed amended to
provide for the highest permissible rate.  If there are no Obligations
outstanding, Bank shall refund to Borrower such excess.

                 (e)     PAYMENTS OF INTEREST.  All accrued but unpaid interest
on the Loans, calculated in accordance with this Section 2.5, shall be due and
payable, in arrears, on the first Business Day of each and every month.

                 (f)     CHANGE IN APPLICABLE MARGIN.  Changes in the Applicable
Margin, resulting from a change in the Leverage Ratio, shall become effective on
the 45th day following the last day of each fiscal quarter of Borrower, and
shall be based on the Leverage Ratio disclosed in the Compliance Certificate
with respect to such fiscal quarter; PROVIDED, HOWEVER, for purposes of
determining the aforementioned margins, (i) until Borrower accurately completes
and delivers to Bank the first Compliance Certificate due


                                          19
<PAGE>

hereunder, the Leverage Ratio shall be conclusively presumed to be greater than
3.5:1.0 and (ii) if Borrower fails to deliver to Bank an accurately completed
Compliance Certificate within forty-five (45) days following the end of each
fiscal quarter of Borrower, the Leverage Ratio shall be conclusively presumed to
be greater than 3.5:1.0 until the applicable Compliance Certificate has been so
completed and delivered to Bank.

          2.6    NOTE; STATEMENTS OF OBLIGATIONS.  The Revolving Loans and
Borrower's obligation to repay the same shall be evidenced by the Note, this
Agreement and the books and records of Bank.  Bank shall render monthly
statements of the Loans to Borrower, including statements of all principal and
interest owing on the Loans, and all Fees and Bank Expenses owing, and such
statements shall be presumed to be correct and accurate and constitute an
account stated between Borrower and Bank unless, within thirty (30) days after
receipt thereof by Borrower, Borrower delivers to Bank, at the address specified
in Section 9.1, written objection thereof specifying the error or errors, if
any, contained in any such statement.

          2.7    HOLIDAYS.  Any principal or interest in respect of the Loans
which would otherwise become due on a day other than a Business Day, shall
instead become due on the next succeeding Business Day and such adjustment shall
be reflected in the computation of interest; PROVIDED, HOWEVER, that in the
event that such due date shall, subsequent to the specification thereof by Bank,
for any reason no longer constitute a Business Day, Bank may change such
specified due date in accordance with this Section 2.7.

          2.8    TIME AND PLACE OF PAYMENTS.

                 (a)     All payments due hereunder shall be made available to

Payment Fee shall be due and payable on the eleventh day after the due date of
the overdue payment with respect thereto.

permanently reduce the Revolving Credit Commitment at any time, upon three (3)
Business Days' notice to Bank (an "OPTIONAL COMMITMENT REDUCTION"), and Borrower

of payment of any Taxes, Borrower shall furnish to Bank the original or a
certified copy of a receipt evidencing payment thereof.  If no Taxes are payable

furnish to Bank a certificate from each


                                          46
<PAGE>

appropriate taxing authority, or an opinion of counsel acceptable to Bank, in
either case stating that such payment is exempt from or not subject to Taxes.

right, power or privilege hereunder or under any Loan Document shall operate as

other or further exercise thereof or the exercise of any other right, power or
privilege.

orders, directions, ordinances, criteria or guidelines (except to the extent
that it is finally judicially determined to have resulted from the gross

extent that the obligations of Borrower hereunder are unenforceable for any
reason, Borrower hereby agrees to make the maximum contribution to the payment
and satisfaction of such obligations of Bank which is permissible under
applicable law.

in connection therewith regarding security interests in real or personal
property; or (ii) the appointment of a receiver, or the exercise of other
provisional remedies (any and all of which may be initiated pursuant to
applicable law), each controversy, dispute or claim between the parties arising
out of or relating to this Agreement, which controversy, dispute or claim is not
settled in writing within thirty (30) days after the "CLAIM DATE" (defined as
the date on which a party subject to this Agreement gives written notice to all
other parties that a controversy, dispute or claim exists), will be settled by a
reference proceeding in California in accordance with the provisions of Section
638 ET SEQ. of the California Code of Civil Procedure, or their successor
section ("CCP"), which shall constitute the exclusive remedy for the settlement
of any controversy, dispute or claim concerning this Agreement, including
whether such controversy, dispute or claim is subject to the reference
proceeding and except as set forth above, the parties waive their rights to
initiate any legal proceedings against each other in any court or jurisdiction
other than the Superior Court in the County where any real property collateral
is located, or Los Angeles County, if none (the "COURT").  The referee shall be
a retired Judge of the Court selected by mutual agreement of the parties, and if
they cannot so agree within forty-five (45) days after the Claim Date, the
referee shall be promptly selected by the Presiding Judge of the Court (or his
or her representative).  The referee shall be appointed to sit as a temporary
judge, with all of the powers for a temporary judge, as authorized by law, and
upon selection should take and subscribe to the oath of office as provided for
in Rule 244 of the California Rules of Court (or any subsequently enacted Rule).
Each party shall have one peremptory challenge pursuant to CCP Section 170.6.
The referee shall (i) be requested to set the matter for hearing within sixty
(60) days after the Claim Date and (ii) try any and all issues of law or fact
and report a statement of decision upon them, if possible, within ninety (90)
days of the Claim Date.  Any decision rendered by the referee will be final,

in any court in the State of California having jurisdiction.  Any party may
apply for a reference proceeding at any time after thirty (30) days following
notice to any other party of the nature of the controversy, dispute or claim, by
filing a petition for a hearing and/or trial.  All discovery permitted by this
Agreement shall be completed no later than fifteen (15) days before the first
hearing date established by the referee.  The referee may extend such period in
the event of a party's refusal to provide requested discovery for any reason
whatsoever, including, without limitation, legal objections raised to such
discovery or unavailability of a witness due to absence or illness.  No party
shall be entitled to "priority" in conducting discovery.  Depositions may be
taken by either party upon seven (7) days written notice, and request for
production or inspection of documents shall be responded to within ten (10) days
after


                                          50

service.  All disputes relating to discovery which cannot be resolved by the
parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Superior Court is empowered to issue temporary and/or provisional
remedies, as appropriate.

                 (b)     Except as expressly set forth in this Agreement, the
referee shall determine the manner in which the reference proceeding is
conducted including the time and place of all hearings, the order of
presentation of evidence, and all other questions that arise with respect to the
course of the reference proceeding.  All proceedings and hearings conducted
before the referee, except for trial, shall be conducted without a court
reporter except that when any party so requests, a court reporter will be used
at any hearing conducted before the referee.  The party making such a request
shall have the obligation to arrange for and pay for the court reporter.  The
costs of the court reporter at the trial shall be borne equally by the parties.

                 (c)     The referee shall be required to determine all issues
in accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties.  The referee shall issue a single judgment at the
close of the reference proceeding which shall dispose of all of the claims of
the parties that are the subject of the reference.  The parties hereto expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee.  The parties hereto
expressly reserve the right to findings of fact, conclusions of laws, a written
statement of decision, and the right to move for a new trial or a different
judgment, which new trial, if granted, is also to be a reference proceeding
under this provision.

                 (d)     In the event that the enabling legislation which
provides for appointment of a referee is repealed (and no successor statute is
enacted), any dispute between the parties that would otherwise be determined by
the reference procedure herein described will be resolved and determined by
arbitration.  The arbitration will be conducted by a retired judge of the Court,
in accordance with the California Arbitration Act, Section 1280 through Section
1294.2 of the CCP as amended from time to time.  The limitations with respect to
discovery as set forth hereinabove shall apply to any such arbitration

<PAGE>

          9.   RIGHTS AND REMEDIES.

               9.1  During the continuance of an Event of Default, Bank, without
notice or demand, may do any one or more of the following, all of which are
authorized by Borrower:

                    (a)  Settle or adjust disputes and claims directly with
Account Debtors for amounts and upon terms which Bank considers advisable, and
in such cases, Bank will credit the Secured Obligations with only the net
amounts received by Bank in payment of such disputed Accounts after deducting
all Bank Expenses incurred or expended in connection therewith;

                    (b)  Cause Borrower to hold all returned Inventory in trust
for Bank, segregate all returned Inventory from all other property of Borrower
or in Borrower's possession and conspicuously label said returned Inventory as
the property of Bank;

                    (c)  Without notice to or demand upon Borrower or any
guarantor, make such payments and do such acts as Bank considers necessary or
reasonable to protect its security interests in the Collateral.  Borrower agrees
to assemble the Collateral if Bank so requires, and to make the Collateral
available to Bank as Bank may designate.  Borrower authorizes Bank to enter the
premises where the Collateral is located, to take and maintain possession of the
Collateral, or any part of it, and to pay, purchase, contest, or compromise any
encumbrance, charge, or Lien that in Bank's determination appears to conflict
with its security interests and to pay all expenses incurred in connection
therewith.  With respect to any of Borrower's owned or leased premises, Borrower
hereby grants Bank a license to enter into possession of such premises and to
occupy the same, without charge, for up to 120 days in order to exercise any of
Bank's rights or remedies provided herein, at law, in equity, or otherwise;

                    (d)  Without notice to Borrower (such notice being expressly
waived), and without constituting a retention of any collateral in satisfaction
of an obligation (within the meaning of Section 9505 of the Code), set off and
apply to the Secured Obligations any and all (i) balances and Deposit Accounts
of Borrower held by Bank, or (ii) indebtedness at any time owing to or for the
credit or the account of Borrower held by Bank;

                    (e)  Hold, as cash collateral, any and all balances and
Deposit Accounts of Borrower held by Bank, to secure the full and final
repayment of all of the Secured Obligations;

                    (f)  Ship, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner provided
for herein) the Collateral.  Bank is hereby granted a license or other right to
use, without charge, Borrower's labels, patents, copyrights, rights of use of
any name, trade secrets, trade


                                          14
<PAGE>

names, trademarks, service marks, and advertising matter, or any property of a
similar nature, as it pertains to the Collateral, in completing production of,
advertising for sale, and selling any Collateral and Borrower's rights under all
licenses and all franchise agreements shall inure to Bank's benefit;

                    (g)  Sell the Collateral at either a public or private sale,
or both, by way of one or more contracts or transactions, for cash or on terms,
in such manner and at such places (including Borrower's premises) as Bank
determines is commercially reasonable.  It is not necessary that the Collateral
be present at any such sale;

                    (h)  Bank shall give notice of the disposition of the
Collateral as follows:

                         (i)    Bank shall give Borrower and each holder of a
security interest in the Collateral who has filed with Bank a written request
for notice, a notice in writing of the time and place of public sale, or, if the
sale is a private sale or some other disposition other than a public sale is to
be made of the Collateral, then the time on or after which the private sale or
other disposition is to be made;

                         (ii)   The notice shall be personally delivered or
mailed, postage prepaid, to Borrower as provided in SECTION 9.1 of the Loan
Agreement, at least 5 days before the date fixed for the sale, or at least 5
days before the date on or after which the private sale or other disposition is
to be made; no notice needs to be given prior to the disposition of any portion
of the Collateral that is perishable or threatens to decline speedily in value
or that is of a type customarily sold on a recognized market.  Notice to Persons
other than Borrower claiming an interest in the Collateral shall be sent to such
addresses as they have furnished to Bank;

                         (iii)  If the sale is to be a public sale, Bank also
shall give notice of the time and place by publishing a notice one time at least
5 days before the date of the sale in a newspaper of general circulation in the
county in which the sale is to be held;

                    (i)  Bank may credit bid and purchase at any public sale;
and

                    (j)  Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Borrower.  Any excess
will be returned, without interest and subject to the rights of third Persons,
by Bank to Borrower.

               9.2  Upon the exercise by Bank of any power, right, privilege, or
remedy pursuant to this Security Agreement which requires any consent, approval,
registration, qualification, or authorization of any Governmental Authority,
Borrower agrees to execute and deliver, or will cause the execution and delivery
of, all applications, certificates, instruments, assignments, and other
documents and papers that Bank or any


                                          15
<PAGE>

purchaser of the Collateral may be required to obtain for such governmental
consent, approval, registration, qualification, or authorization.

               9.3  The rights and remedies of Bank under this Security
Agreement, the Loan Agreement, the other Loan Documents, and all other
agreements contemplated hereby and thereby shall be cumulative.  Bank shall have
all other rights and remedies not inconsistent herewith as provided under the
Code, by law, or in equity.  No exercise by Bank of any one right or remedy
shall be deemed an election of remedies, and no waiver by Bank of any default on
Borrower's part shall be deemed a continuing waiver of any further defaults.  No
delay by Bank shall constitute a waiver, election or acquiescence with respect
to any right or remedy.

          10.  BANK NOT LIABLE.  So long as Bank complies with the obligations,
if any, imposed by Section 9207 of the Code, Bank shall not otherwise be liable
or responsible in any way or manner for:  (a) the safekeeping of the Collateral;
(b) any loss or damage thereto occurring or arising in any manner or fashion or
from any cause; (c) any diminution in the value thereof; or (d) any act or
default of any carrier, warehouseman, bailee, forwarding agency, or other person
whomsoever.

          11.  INDEFEASIBLE PAYMENT.  The Secured Obligations shall not be
considered indefeasibly paid for purposes of this Security Agreement unless and
until all payments to Bank are no longer subject to any right on the part of any
Person, including Borrower, Borrower as a debtor in possession, or any trustee
(whether appointed under the Bankruptcy Code or otherwise) of Borrower or
Borrower's Assets to invalidate or set aside such payments or to seek to recoup
the amount of such payments or any portion thereof, or to declare same to be
fraudulent or preferential.  In the event that, for any reason, any portion of
such payments to Bank is set aside or restored, whether voluntarily or
involuntarily, after the making thereof, then the obligation intended to be
satisfied thereby shall be revived and continued in full force and effect as if
said payment or payments had not been made.

          12.  NOTICES.  All notices or demands by any party hereto to the other
party and relating to this Security Agreement shall be made in the manner and to
the addresses set forth in Section 9.1 of the Loan Agreement.

          13.  GENERAL PROVISIONS.

               13.1 SUCCESSORS AND ASSIGNS.  This Security Agreement shall bind
and inure to the benefit of the respective successors and assigns of Borrower
and Bank; PROVIDED, HOWEVER, that Borrower may not assign this Security
Agreement nor delegate any of its duties hereunder without Bank's prior written
consent and any prohibited assignment or delegation shall be absolutely void.
No consent by Bank to an assignment by Borrower shall release Borrower from the
Secured Obligations.  Bank reserves its right to sell, assign, transfer,
negotiate, or grant participations in all or any part of, or any interest in,
the rights and benefits hereunder pursuant to and in accordance with the
provisions of the Loan


                                          16
<PAGE>

Agreement.  In connection therewith, Bank may disclose all documents and
information which Bank now or hereafter may have relating to Borrower,
Borrower's business, or the Collateral to any such prospective or actual
Transferee, subject to the terms of Section 9.5(e) of the Loan Agreement.

               13.2 EXHIBITS AND SCHEDULES.  All of the exhibits and schedules
attached hereto shall be deemed incorporated by reference.

               13.3 NO PRESUMPTION AGAINST ANY PARTY.  Neither this Security
Agreement nor any uncertainty or ambiguity herein shall be construed or resolved
against Bank or Borrower, whether under any rule of construction or otherwise.
On the contrary, this Security Agreement has been reviewed by each of the
parties and their counsel and shall be construed and interpreted according to
the ordinary meaning of the words used so as to accomplish fairly the purposes
and intentions of all parties hereto.

               13.4 AMENDMENTS AND WAIVERS.  Any provision of this Agreement or
any of the Loan Documents to which Borrower is a party may be amended or waived
if, but only if, such amendment or waiver is in writing and is signed by the
party asserted to be bound thereby, and then such amendment or waiver shall be
effective only in the specific instance and specific purpose for which given.

               13.5 COUNTERPARTS; INTEGRATION; EFFECTIVENESS.  This Security
Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument.  This Security Agreement constitutes the entire agreement
and understanding among the parties hereto and supersedes any and all prior
agreements and understandings, oral or written, relating to the subject matter
hereof.  This Security Agreement shall become effective when executed by each of
the parties hereto and delivered to Bank.

               13.6 SEVERABILITY.  The provisions of this Agreement are
severable.  The invalidity, in whole or in part, of any provision of this
Agreement shall not affect the validity or enforceability of any other of its
provisions.  If one or more provisions hereof shall be declared invalid or
unenforceable, the remaining provisions shall remain in full force and effect
and shall be construed in the broadest possible manner to effectuate the
purposes hereof.

          14.  GOVERNING LAW.  This Security Agreement shall be deemed to have
been made in the State of California and the validity, construction,
interpretation, and enforcement hereof, and the rights of the parties hereto,
shall be determined under, governed by, and construed in accordance with the
internal laws of the State of California, without regard to principles of
conflicts of law.

          15.  JUDICIAL REFERENCE.

               15.1 Other than (i) nonjudicial foreclosure and all matters in
connection therewith regarding security interests in real or personal property;
or (ii) the appointment of a receiver, or the exercise of other provisional
remedies (any and all of which may be initiated pursuant to applicable law),
each controversy, dispute or claim between the parties arising out of or
relating to this Security Agreement, which controversy, dispute or claim is not
settled in writing within thirty (30) days after the "Claim Date" (defined as
the date on which Borrower or Bank gives written notice to the other that a
controversy, dispute or claim exists), will be settled by a reference proceeding
in California in accordance with the provisions of Section 638 ET SEQ. of the
California Code of Civil Procedure, or their successor section ("CCP"), which
shall constitute the exclusive remedy for the settlement of any controversy,
dispute or claim concerning this Security Agreement, including whether such
controversy, dispute or claim is subject to the reference proceeding and except
as set forth above, the parties waive their rights to initiate any legal
proceedings against each other in any court or jurisdiction other than the
Superior Court in the County where any real property Collateral is located or
Los Angeles County if none (the "Court").  The referee shall be a retired Judge
of the Court selected by mutual agreement of the parties, and if they cannot so
agree within forty-five (45) days after the Claim Date, the referee shall be
promptly selected by the Presiding Judge of the Court (or his representative).
The referee shall be appointed to sit as a temporary judge, with all of the
powers for a temporary judge, as authorized by law, and upon selection should
take and subscribe to the oath of office as provided for in Rule 244 of the
California Rules of Court (or any subsequently enacted Rule).  Each party shall
have one peremptory challenge pursuant to CCP Section 170.6.  The referee shall
(a) be requested to set the matter for hearing within sixty (60) days after the
Claim Date and (b) try any and all issues of law or fact and report a statement
of decision upon them, if possible, within ninety (90) days of the Claim Date.
Any decision rendered by the referee will be final, binding and conclusive and
judgment shall be entered pursuant to CCP Section 644 in any court in the State
of California having jurisdiction.  Any party may apply for a reference
proceeding at any time after thirty (30) days following notice to any other
party of the nature of the controversy, dispute or claim, by filing a petition
for a hearing and/or trial.  All discovery permitted by this Security Agreement
shall be completed no later than fifteen (15) days before the first hearing date
established by the referee.  The referee may extend such period in the event of
a party's refusal to provide requested discovery for any reason whatsoever,
including, without limitation, legal objections raised to such discovery or
unavailability of a witness due to absence or illness.  No party shall be
entitled to "priority" in conducting discovery.  Depositions may be taken by
either party upon seven (7) days written notice, and request for production or
inspection of documents shall be responded to within ten (10) days after
service.  All disputes relating to discovery which cannot be resolved by the
parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Superior Court is empowered to issue temporary and/or provisional
remedies, as appropriate.

               15.2 Except as expressly set forth in this Security Agreement,
the referee shall determine the manner in which the reference proceeding is
conducted including the time and place of all hearings, the order of
presentation of evidence, and all other questions that arise with respect to the
course of the reference proceeding.  All proceedings and hearings conducted
before the referee, except for trial, shall be conducted without a court
reporter except that when any party so requests, a court reporter will be used
at any hearing conducted before the referee.  The party making such a request
shall have the obligation to arrange for and pay for the court reporter.  The
costs of the court reporter at the trial shall be borne equally by the parties.

               15.3 The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties.  The referee shall issue a single judgment at the
close of the reference proceeding which shall dispose of all of the claims of
the parties that are the subject of the reference.  The parties hereto expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee.  The parties hereto
expressly reserve the right to findings of fact, conclusions of laws, a written
statement of decision, and the right to move for a new trial or a different
judgment, which new trial, if granted, is also to be a reference proceeding
under this provision.

               15.4 In the event that the enabling legislation which provides
for appointment of a referee is repealed (and no successor statute is enacted),
any dispute between the parties that would otherwise be determined by the
reference procedure herein described will be resolved and determined by
arbitration.  The arbitration will be conducted by a retired judge of the Court,
in accordance with the California Arbitration Act, Section 1280 through Section
1294.2 of the CCP as amended from time to time.  The limitations with respect to
discovery as set forth hereinabove shall apply to any such arbitration
proceeding.

                                 CONTINUING GUARANTY


          This CONTINUING GUARANTY (this "GUARANTY"), dated as of July 3, 1997,
is executed and delivered by PROSPECT MEDICAL SYSTEMS, INC., a Delaware
corporation ("GUARANTOR"), with reference to the following facts:

                                   R E C I T A L S

          A.   Prospect Medical Holdings, Inc., a Delaware corporation
("BORROWER"), and Imperial Bank, a California banking corporation ("BANK"), have
entered into that certain Loan Agreement, dated as of July 3, 1997 (as the same
may be amended, restated, supplemented or otherwise modified from time to time,
the "LOAN AGREEMENT").

          B.   Guarantor is materially interested in the financial success of
Borrower, agrees that the Loan Agreement is in Borrower's best interests, and
acknowledges that the execution and delivery of this Guaranty formed a material
part of the consideration to Bank to induce Bank to enter into the Loan
Agreement.

                                  A G R E E M E N T

          NOW, THEREFORE, in consideration of the foregoing, Guarantor hereby
agrees, in favor of Bank, as follows:

          1.   DEFINITIONS AND CONSTRUCTION.

               (a)  DEFINITIONS.  All initially capitalized terms used but not
defined herein shall have the meanings assigned to such terms in the Loan
Agreement.  In addition, the following terms, as used in this Guaranty, shall
have the following meanings:

                    "GUARANTEED OBLIGATIONS" means any and all obligations,
indebtedness, or liabilities of any kind or character owed by Borrower to Bank
(including without limitation, all principal and interest owing under the Loans,
all Bank Expenses, the Fees, any other fees and expenses due under the Loan
Agreement, and all other indebtedness evidenced by the Loan Agreement and the
other Loan Documents), including all such obligations, indebtedness, or
liabilities, whether for principal, interest (including any interest which, but
for the application of the provisions of the Bankruptcy Code, would have accrued
on such amounts), premium, reimbursement obligations, fees, costs, expenses
(including, attorneys' fees and attorneys' fees incurred pursuant to proceedings
arising under the Bankruptcy Code), or indemnity obligations, whether
heretofore, now, or hereafter made, incurred, or created, whether voluntarily or
involuntarily made, incurred, or created, whether secured or unsecured (and if
secured, regardless of the nature or extent of the security), whether absolute
or contingent, liquidated or unliquidated, determined or indeterminate, whether
Borrower is liable individually or jointly with others, and whether


                                          1
<PAGE>

recovery is or hereafter becomes barred by any statute of limitations or
otherwise becomes unenforceable for any reason whatsoever, including any act or
failure to act by Bank.

                    "LOAN DOCUMENTS" shall mean the Loan Agreement, this
Guaranty, and the other Loan Documents (as defined in the Loan Agreement).

               (b)  CONSTRUCTION.  Unless the context of this Guaranty clearly
requires otherwise, references to the plural include the singular, references to
the singular include the plural, and the term "including" is not limiting.  The
words "hereof," "herein," "hereby," "hereunder," and other similar terms refer
to this Guaranty as a whole and not to any particular provision of this
Guaranty.  Any reference herein to any of the Loan Documents includes any and
all alterations, amendments, extensions, modifications, renewals, or supplements
thereto or thereof, as applicable.  Neither this Guaranty nor any uncertainty or
ambiguity herein shall be construed or resolved against Bank or Guarantor,
whether under any rule of construction or otherwise.  On the contrary, this
Guaranty has been reviewed by Guarantor, Bank, and their respective counsel, and
shall be construed and interpreted according to the ordinary meaning of the
words used so as to fairly accomplish the purposes and intentions of Bank and
Guarantor.

          2.   GUARANTEED OBLIGATIONS.  Guarantor hereby irrevocably and
unconditionally guarantees to Bank, as and for Guarantor's own debt, until final
and indefeasible payment thereof has been made, (a) payment of the Guaranteed
Obligations, in each case when and as the same shall become due and payable,
whether at maturity, pursuant to a mandatory prepayment requirement, by
acceleration, or otherwise; it being the intent of Guarantor that the guaranty
set forth herein shall be a guaranty of payment and not a guaranty of
collection, and (b) the punctual and faithful performance, keeping, observance,
and fulfillment by Borrower of all of the agreements, conditions, covenants, and
obligations of Borrower contained in the Loan Documents.

          3.   CONTINUING GUARANTY.  This Guaranty includes Guaranteed
Obligations arising under successive transactions continuing, compromising,
extending, increasing, modifying, releasing, or renewing the Guaranteed
Obligations, changing the interest rate, payment terms, or other terms and
conditions thereof, or creating new or additional Guaranteed Obligations after
prior Guaranteed Obligations have been satisfied in whole or in part.  To the
maximum extent permitted by law, Guarantor hereby waives and agrees not to
assert any right Guarantor has under Section 2815 of the California Civil Code,
or otherwise, to revoke this Guaranty as to future indebtedness.

          4.   PERFORMANCE UNDER THIS GUARANTY.  In the event that Borrower
fails to make any payment of any Guaranteed Obligations on or before the due
date thereof, or if Borrower shall fail to perform, keep, observe, or fulfill
any other obligation referred to in clause (b) of Section 2 hereof in the manner
provided in the Loan Documents, Guarantor immediately shall cause such payment
to be made or each of such obligations to be performed, kept, observed, or
fulfilled.


                                          2
<PAGE>

          5.   PRIMARY OBLIGATIONS.  This Guaranty is a primary and original
obligation of Guarantor, is not merely the creation of a surety relationship,
and is an absolute, unconditional, and continuing guaranty of payment and
performance which shall remain in full force and effect without respect to
future changes in conditions, including any change of law or any invalidity or
irregularity with respect to the Loan Documents.  Guarantor agrees that
Guarantor is severally and not jointly and severally liable, with any other
guarantor of the Guaranteed Obligations, to Bank, to the extent set forth in
Section 2 hereof, that the obligations of Guarantor hereunder are independent of
the obligations of Borrower or any other guarantor, and that a separate action
may be brought against Guarantor whether such action is brought against Borrower
or any other guarantor or whether Borrower or any such other guarantor is joined
in such action.  Guarantor agrees that Guarantor's liability hereunder shall be
immediate and shall not be contingent upon the exercise or enforcement by Bank
of whatever remedies it may have against Borrower or any other guarantor, or the
enforcement of any lien or realization upon any security Bank may at any time
possess.  Guarantor agrees that any release which may be given by Bank to
Borrower or any other guarantor shall not release Guarantor.  Guarantor consents
and agrees that Bank shall be under no obligation to marshal any assets of
Borrower or any other guarantor in favor of Guarantor, or against or in payment
of any or all of the Guaranteed Obligations.

          6.   WAIVERS.

               (a)  Guarantor absolutely, unconditionally, knowingly, and
expressly waives:

                    (i)    (1) notice of acceptance hereof; (2) notice of any
loans or other financial accommodations made or extended under the Loan
Documents or the creation or existence of any Guaranteed Obligations; (3) notice
of the amount of the Guaranteed Obligations, subject, however, to Guarantor's
right to make inquiry of Bank to ascertain the amount of the Guaranteed
Obligations at any reasonable time; (4) notice of any adverse change in the
financial condition of Borrower or of any other fact that might increase
Guarantor's risk hereunder; (5) notice of presentment for payment, demand,
protest, and notice thereof as to any instruments among the Loan Documents;
(6) notice of any Unmatured Event of Default or Event of Default; and (7) all
other notices (except if such notice is specifically required to be given to
Guarantor hereunder or under the Loan Documents) and demands to which Guarantor
might otherwise be entitled.

                    (ii)   its right, under Sections 2845 or 2850 of the
California Civil Code, or otherwise, to require Bank to institute suit against,
or to exhaust any rights and remedies which Bank has or may have against,
Borrower or any third party, or against any collateral for the Guaranteed
Obligations provided by Borrower or any third party.  In this regard, Guarantor
agrees that Guarantor is bound to the payment of all Guaranteed Obligations,
whether now existing or hereafter accruing, as fully as if such Guaranteed
Obligations were directly owing to Bank by Guarantor.  Guarantor further waives
any defense arising by reason of any disability or other defense (other than the
defense that the


                                          3
<PAGE>

Guaranteed Obligations shall have been fully and finally performed and
indefeasibly paid) of Borrower or by reason of the cessation from any cause
whatsoever of the liability of Borrower in respect thereof.

                    (iii)  (1) any rights to assert against Bank any defense
(legal or equitable), set-off, counterclaim, or claim which Guarantor may now or
at any time hereafter have against Borrower or any other party liable to Bank;
(2) any defense, set-off, counterclaim, or claim, of any kind or nature, arising
directly or indirectly from the present or future lack of perfection,
sufficiency, validity, or enforceability of the Guaranteed Obligations or any
security therefor; (3) any defense Guarantor has to performance hereunder, and
any right Guarantor has to be exonerated, provided by Sections 2819, 2822, or
2825 of the California Civil Code, or otherwise, arising by reason of:  the
impairment or suspension of Bank's rights or remedies against Borrower; the
alteration by Bank of the Guaranteed Obligations; any discharge of Borrower's
obligations to Bank by operation of law as a result of Bank's intervention or
omission; or the acceptance by Bank of anything in partial satisfaction of the
Guaranteed Obligations; (4) the benefit of any statute of limitations affecting
Guarantor's liability hereunder or the enforcement thereof, and any act which
shall defer or delay the operation of any statute of limitations applicable to
the Guaranteed Obligations shall similarly operate to defer or delay the
operation of such statute of limitations applicable to Guarantor's liability
hereunder.

               (b)  Guarantor absolutely, unconditionally, knowingly, and
expressly waives any defense arising by reason of or deriving from (i) any claim
or defense based upon an election of remedies by Bank including any defense
based upon an election of remedies by Bank under the provisions of
Sections 580a, 580b, 580d, and 726 of the California Code of Civil Procedure or
any similar law of California or any other jurisdiction; or (ii) any election by
Bank under Bankruptcy Code Section 1111(b) to limit the amount of, or any
collateral securing, its claim against Borrower.  Pursuant to Section 2856 of
the California Civil Code:

               Guarantor waives all rights and defenses arising out of an
election of remedies by the creditor, even though that election of remedies,
such as a nonjudicial foreclosure with respect to security for a guaranteed
obligation, has destroyed Guarantor's rights of subrogation and reimbursement
against Borrower by the operation of Section 580(d) of the California Code of
Civil Procedure or otherwise.

               Guarantor waives all rights and defenses that Guarantor may have
because Borrower's Obligations are secured by real property.  This means, among
other things:

               (1)  Bank may collect from Guarantor without first foreclosing on
any real or personal property collateral pledged by Borrower.

               (2)  If Bank forecloses on any real property collateral pledged
by Borrower:


                                          4
<PAGE>

                    (A)    The amount of the Guaranteed Obligations may be
reduced only by the price for which that collateral is sold at the foreclosure
sale, even if the collateral is worth more than the sale price.

                    (B)    Bank may collect from Guarantor even if Bank, by
foreclosing on the real property collateral, has destroyed any right Guarantor
may have to collect from Borrower.

               This is an unconditional and irrevocable waiver of any rights and
defenses Guarantor may have because Borrower's Obligations are secured by real
property.  These rights and defenses include, but are not limited to, any rights
or defenses based upon Section 580a, 580b, 580d, or 726 of the California Code
of Civil Procedure.

If any of the Guaranteed Obligations at any time are secured by a mortgage or
deed of trust upon real property, Bank may elect, in its sole discretion, upon a
default with respect to the Guaranteed Obligations, to foreclose such mortgage
or deed of trust judicially or nonjudicially in any manner permitted by law,
before or after enforcing the Loan Documents, without diminishing or affecting
the liability of Guarantor hereunder except to the extent the Guaranteed
Obligations are repaid with the proceeds of such foreclosure.  Guarantor
understands that (a) by virtue of the operation of California's antideficiency
law applicable to nonjudicial foreclosures, an election by Bank nonjudicially to
foreclose such a mortgage or deed of trust probably would have the effect of
impairing or destroying rights of subrogation, reimbursement, contribution, or
indemnity of Guarantor against Borrower or other guarantors or sureties, and
(b) absent the waiver given by Guarantor, such an election would prevent Bank
from enforcing the Loan Documents against Guarantor.  Understanding the
foregoing, and understanding that Guarantor is hereby relinquishing a defense to
the enforceability of the Loan Documents, Guarantor hereby waives any right to
assert against Bank any defense to the enforcement of the Loan Documents,
whether denominated "estoppel" or otherwise, based on or arising from an
election by Bank nonjudicially to foreclose any such mortgage or deed of trust.
Guarantor understands that the effect of the foregoing waiver may be that
Guarantor may have liability hereunder for amounts with respect to which
Guarantor may be left without rights of subrogation, reimbursement,
contribution, or indemnity against Borrower or other guarantors or sureties.
Guarantor also agrees that the "fair market value" provisions of Section 580a of
the California Code of Civil Procedure shall have no applicability with respect
to the determination of Guarantor's liability under the Loan Documents.

               (c)  Guarantor hereby absolutely, unconditionally, knowingly, and
expressly waives:  (i) any right of subrogation Guarantor has or may have as
against Borrower with respect to the Guaranteed Obligations; (ii) any right to
proceed against Borrower or any other person or entity, now or hereafter, for
contribution, indemnity, reimbursement, or any other suretyship rights and
claims, whether direct or indirect, liquidated or contingent, whether arising
under express or implied contract or by operation of law, which Guarantor may
now have or hereafter have as against Borrower with respect


                                          5
<PAGE>

to the Guaranteed Obligations; and (iii) any right to proceed or seek recourse
against or with respect to any property or asset of Borrower.

               (d)  WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER
PROVISION SET FORTH IN THIS GUARANTY, GUARANTOR HEREBY ABSOLUTELY, KNOWINGLY,
UNCONDITIONALLY, AND EXPRESSLY WAIVES AND AGREES NOT TO ASSERT ANY AND ALL
BENEFITS OR DEFENSES ARISING DIRECTLY OR INDIRECTLY UNDER ANY ONE OR MORE OF
CALIFORNIA CIVIL CODE SECTIONS 2799, 2808, 2809, 2810, 2815, 2819, 2820, 2821,
2822, 2825, 2839, 2845, 2848, 2849, AND 2850, CALIFORNIA CODE OF CIVIL PROCEDURE
SECTIONS 580A, 580B, 580C, 580D, AND 726, AND CHAPTER 2 OF TITLE 14 OF PART 4 OF
DIVISION 3 OF THE CALIFORNIA CIVIL CODE.

          7.   RELEASES.  Guarantor consents and agrees that, without notice to
or by Guarantor, and without affecting or impairing the obligations of Guarantor
hereunder, Bank may, by action or inaction:

               (a)  compromise, settle, extend the duration or the time for the
                    payment of, or discharge the performance of, or may refuse
                    to or otherwise not enforce this Guaranty, the other Loan
                    Documents, or any part thereof, with respect to Borrower or
                    any other Person;

               (b)  release Borrower or any other Person or grant other
                    indulgences to Borrower or any other Person in respect
                    thereof;

               (c)  amend or modify in any manner and at any time (or from time
                    to time) any of the Loan Documents; or

               (d)  release or substitute any other guarantor, if any, of the
                    Guaranteed Obligations, or enforce, exchange, release, or
                    waive any security for the Guaranteed Obligations or any
                    other guaranty of the Guaranteed Obligations, or any portion
                    thereof.

          8.   NO ELECTION.  Bank shall have all of the rights to seek recourse
against Guarantor to the fullest extent provided for herein, and no election by
Bank to proceed in one form of action or proceeding, or against any party, or on
any obligation, shall constitute a waiver of Bank's right to proceed in any
other form of action or proceeding or against other parties unless Bank has
expressly waived such right in writing.  Specifically, but without limiting the
generality of the foregoing, no action or proceeding by Bank under any document
or instrument evidencing the Guaranteed Obligations shall serve to diminish the


                                          6
<PAGE>

liability of Guarantor under this Guaranty except to the extent that Bank
finally and unconditionally shall have realized indefeasible payment by such
action or proceeding.

          9.   INDEFEASIBLE PAYMENT.  The Guaranteed Obligations shall not be
considered indefeasibly paid for purposes of this Guaranty unless and until all
payments to Bank are no longer subject to any right on the part of any Person,
including Borrower, Borrower as a debtor in possession, or any trustee (whether
appointed under the Bankruptcy Code or otherwise) of any of Borrower's assets,
to invalidate or set aside such payments or to seek to recoup the amount of such
payments or any portion thereof, or to declare same to be fraudulent or
preferential.  Upon such full and final performance and indefeasible payment of
the Guaranteed Obligations, whether by Borrower pursuant to the Loan Agreement
or by any other Person, Bank shall have no obligation whatsoever to transfer or
assign its interests in the Loan Documents to Guarantor.  In the event that, for
any reason, any portion of such payments to Bank is set aside or restored,
whether voluntarily or involuntarily, after the making thereof, then the
obligation intended to be satisfied thereby shall be revived and continued in
full force and effect as if said payment or payments had not been made, and
Guarantor shall be liable for the full amount Bank is required to repay plus any
and all costs and expenses (including attorneys' fees and expenses and
attorneys' fees and expenses incurred pursuant to proceedings arising under the
Bankruptcy Code) paid by Bank in connection therewith.

          10.  FINANCIAL CONDITION OF BORROWER.  Guarantor represents and
warrants to Bank that Guarantor is currently informed of the financial condition
of Borrower and of all other circumstances which a diligent inquiry would reveal
and which bear upon the risk of nonpayment of the Guaranteed Obligations.
Guarantor further represents and warrants to Bank that Guarantor has read and
understands the terms and conditions of the Loan Documents.  Guarantor hereby
covenants that Guarantor will continue to keep informed of Borrower's financial
condition, the financial condition of other guarantors, if any, and of all other
circumstances which bear upon the risk of nonpayment or nonperformance of the
Guaranteed Obligations.

          11.  SUBORDINATION.  Guarantor hereby agrees that any and all present
and future indebtedness of Borrower owing to Guarantor is postponed in favor of
and subordinated to payment, in full, in cash, of the Guaranteed Obligations.
In this regard, no payment of any kind whatsoever shall be made with respect to
such indebtedness until the Guaranteed Obligations have been indefeasibly paid
in full.

          12.  PAYMENTS; APPLICATION.  All payments to be made hereunder by
Guarantor shall be made in lawful money of the United States of America at the
time of payment, shall be made in immediately available funds, and shall be made
without deduction (whether for taxes or otherwise) or offset.  All payments made
by Guarantor hereunder shall be applied as follows: first, to all costs and
expenses (including attorneys' fees and expenses and attorneys' fees and
expenses incurred pursuant to proceedings arising under the Bankruptcy Code)
incurred by Bank in enforcing this Guaranty or in collecting the Guaranteed
Obligations; second, to all accrued and unpaid interest, premium, if any, and


                                          7
<PAGE>

fees owing to Bank constituting Guaranteed Obligations; and third, to the
balance of the Guaranteed Obligations.

          13.  REPRESENTATIONS AND WARRANTIES.  Guarantor hereby represents and
warrants to Bank that:

               (a)  Guarantor is a corporation duly organized and existing under
the laws of Delaware and has the power and authority to own its own properties
and assets, and to transact the business in which it is engaged, and is properly
licensed, qualified to do business and in good standing in every jurisdiction
where the conduct of its business requires it to be so qualified.

               (b)  The execution, delivery and performance of this Guaranty are
within Guarantor's powers, are not in conflict with the terms of any charter,
bylaw, [certificate/articles] of incorporation or other organization papers of
Guarantor, and do not result in a breach of or constitute a default under any
contract, obligation, indenture or other instrument to which Guarantor is a
party or by which Guarantor is bound or affected.  There is no law, rule or
regulation, nor is there any judgment, decree or order of any court or
governmental authority binding on Guarantor which would be contravened by the
execution, delivery, performance or enforcement of this Guaranty and the other
Loan Documents to which Guarantor is a party.

               (c)  Guarantor has taken all corporate action necessary to
authorize the execution and delivery of this Guaranty and the other Loan
Documents to which Guarantor is a party, and the consummation of the
transactions contemplated hereby and thereby.  Upon their execution and delivery
in accordance with their respective terms, this Guaranty and the other Loan
Documents to which Guarantor is a party will constitute legal, valid and binding
agreements and obligations of Guarantor enforceable against Guarantor in
accordance with their respective terms, except as enforceability may be limited
by bankruptcy, insolvency, fraudulent conveyance, and similar laws and equitable
principles affecting the enforcement of creditors' rights generally.

               (d)  No approval, consent, exemption or other action by, or
notice to or filing with, any governmental authority is necessary in connection
with the execution, delivery, performance or enforcement of this Guaranty and
the other Loan Documents to which Guarantor is a party except as may have been
obtained by Guarantor and certified copies of which have been delivered to Bank.

               (e)  Guarantor has no Debt other than Debt owing to Bank
hereunder, and Guarantor covenants and agrees that until the indefeasible
payment, performance and satisfaction in full of the Guaranteed Obligations,
Guarantor will not create, incur, assume or suffer to exist any Debt without the
prior written consent of Bank.

          14.  ATTORNEYS' FEES AND COSTS.  Guarantor agrees to pay, on demand,
all attorneys' fees (including attorneys' fees incurred pursuant to proceedings
arising under the


                                          8
<PAGE>

Bankruptcy Code) and all other costs and expenses which may be incurred by Bank
in the enforcement of this Guaranty or in any way arising out of, or
consequential to the protection, assertion, or enforcement of the Guaranteed
Obligations (or any security therefor), whether or not suit is brought.

          15.  NOTICES.  All notices, requests and other communications to any
party hereunder shall be sent in accordance with Section 9.1 of the Loan

the parties that are the subject of the reference.  The parties hereto expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee.  The parties hereto

interests in the Collateral.  Guarantor agrees that neither Bank, nor any of its
designees or attorneys-in-fact, will be liable for any act of commission or

affect Guarantor's title to, or the security interest of Bank in, any of the
Collateral; and (iii) upon demand of Bank, allow inspection of Collateral by

               4.3  With respect to the Negotiable Collateral (other than drafts
received in the ordinary course of business so long as no Event of Default is
continuing), Guarantor shall, immediately upon request by Bank, endorse (where
appropriate) and assign the Negotiable Collateral over to Bank, and deliver to
Bank actual physical possession of the Negotiable Collateral to Bank together
with any instruments of transfer or assignment, all in form and substance
satisfactory to Bank, in order to fully perfect the security interest therein of
Bank.

               4.4  Guarantor shall cooperate with Bank in obtaining a control
agreement in form and substance satisfactory to Bank with respect to all Deposit
Accounts and Investment Property.

                                          13
<PAGE>

                    (a)  Settle or adjust disputes and claims directly with
Account Debtors for amounts and upon terms which Bank considers advisable, and
in such cases, Bank will credit the Secured Obligations with only the net
amounts received by Bank in payment of such disputed Accounts after deducting
all Bank Expenses incurred or expended in connection therewith;

                    (b)  Cause Guarantor to hold all returned Inventory in trust
for Bank, segregate all returned Inventory from all other property of Guarantor
or in Guarantor's possession and conspicuously label said returned Inventory as
the property of Bank;

                    (c)  Without notice to or demand upon Guarantor or any
guarantor, make such payments and do such acts as Bank considers necessary or
reasonable to protect its security interests in the Collateral.  Guarantor
agrees to assemble the Collateral if Bank so requires, and to make the
Collateral available to Bank as Bank may designate.  Guarantor authorizes Bank
to enter the premises where the Collateral is located, to take and maintain
possession of the Collateral, or any part of it, and to pay, purchase, contest,
or compromise any encumbrance, charge, or Lien that in Bank's determination
appears to conflict with its security interests and to pay all expenses incurred
in connection therewith.  With respect to any of Guarantor's owned or leased
premises, Guarantor hereby grants Bank a license to enter into possession of
such premises and to occupy the same, without charge, for up to 120 days in
order to exercise any of Bank's rights or remedies provided herein, at law, in
equity, or otherwise;

                    (d)  Without notice to Guarantor (such notice being
expressly waived), and without constituting a retention of any collateral in
satisfaction of an obligation (within the meaning of Section 9505 of the Code),
set off and apply to the Secured Obligations any and all (i) balances and
Deposit Accounts of Guarantor held by Bank, or (ii) indebtedness at any time
owing to or for the credit or the account of Guarantor held by Bank;

                    (e)  Hold, as cash collateral, any and all balances and
Deposit Accounts of Guarantor held by Bank, to secure the full and final
repayment of all of the Secured Obligations;

                    (f)  Ship, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner provided
for herein) the Collateral.  Bank is hereby granted a license or other right to
use, without charge, Guarantor's labels, patents, copyrights, rights of use of
any name, trade secrets, trade names, trademarks, service marks, and advertising
matter, or any property of a similar nature, as it pertains to the Collateral,
in completing production of, advertising for sale, and selling any Collateral
and Guarantor's rights under all licenses and all franchise agreements shall
inure to Bank's benefit;

                    (g)  Sell the Collateral at either a public or private sale,
or both, by way of one or more contracts or transactions, for cash or on terms,
in such manner


                                          14
<PAGE>

and at such places (including Guarantor's premises) as Bank determines is
commercially reasonable.  It is not necessary that the Collateral be present at
any such sale;

                    (h)  Bank shall give notice of the disposition of the
Collateral as follows:

                         (i)    Bank shall give Guarantor and each holder of a
security interest in the Collateral who has filed with Bank a written request
for notice, a notice in writing of the time and place of public sale, or, if the
sale is a private sale or some other disposition other than a public sale is to
be made of the Collateral, then the time on or after which the private sale or
other disposition is to be made;

                         (ii)   The notice shall be personally delivered or
mailed, postage prepaid, to Guarantor as provided in SECTION 15 of the Guaranty,
at least 5 days before the date fixed for the sale, or at least 5 days before
the date on or after which the private sale or other disposition is to be made;
no notice needs to be given prior to the disposition of any portion of the
Collateral that is perishable or threatens to decline speedily in value or that
is of a type customarily sold on a recognized market.  Notice to Persons other
than Guarantor claiming an interest in the Collateral shall be sent to such
addresses as they have furnished to Bank;

                         (iii)  If the sale is to be a public sale, Bank also
shall give notice of the time and place by publishing a notice one time at least
5 days before the date of the sale in a newspaper of general circulation in the
county in which the sale is to be held;

                    (i)  Bank may credit bid and purchase at any public sale;
and

                    (j)  Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Guarantor.  Any excess
will be returned, without interest and subject to the rights of third Persons,
by Bank to Guarantor.

               9.2  Upon the exercise by Bank of any power, right, privilege, or
remedy pursuant to this Security Agreement which requires any consent, approval,
registration, qualification, or authorization of any Governmental Authority,
Guarantor agrees to execute and deliver, or will cause the execution and
delivery of, all applications, certificates, instruments, assignments, and other
documents and papers that Bank or any purchaser of the Collateral may be
required to obtain for such governmental consent, approval, registration,
qualification, or authorization.

               9.3  The rights and remedies of Bank under this Security
Agreement, the Guaranty, the other Loan Documents, and all other agreements
contemplated hereby and thereby shall be cumulative.  Bank shall have all other
rights and remedies not inconsistent herewith as provided under the Code, by
law, or in equity.  No exercise by Bank of any one right or remedy shall be
deemed an election of remedies, and


                                          15
<PAGE>

no waiver by Bank of any default on Guarantor's part shall be deemed a
continuing waiver of any further defaults.  No delay by Bank shall constitute a
waiver, election or acquiescence with respect to any right or remedy.

          10.  BANK NOT LIABLE.  So long as Bank complies with the obligations,
if any, imposed by Section 9207 of the Code, Bank shall not otherwise be liable
or responsible in any way or manner for:  (a) the safekeeping of the Collateral;
(b) any loss or damage thereto occurring or arising in any manner or fashion or
from any cause; (c) any diminution in the value thereof; or (d) any act or
default of any carrier, warehouseman, bailee, forwarding agency, or other person
whomsoever.

          11.  INDEFEASIBLE PAYMENT.  The Secured Obligations shall not be
considered indefeasibly paid for purposes of this Security Agreement unless and
until all payments to Bank are no longer subject to any right on the part of any
Person, including Guarantor, Guarantor as a debtor in possession, or any trustee
(whether appointed under the Bankruptcy Code or otherwise) of Guarantor or
Guarantor's Assets to invalidate or set aside such payments or to seek to recoup
the amount of such payments or any portion thereof, or to declare same to be
fraudulent or preferential.  In the event that, for any reason, any portion of
such payments to Bank is set aside or restored, whether voluntarily or
involuntarily, after the making thereof, then the obligation intended to be
satisfied thereby shall be revived and continued in full force and effect as if
said payment or payments had not been made.

          12.  NOTICES.  All notices or demands by any party hereto to the other
party and relating to this Security Agreement shall be made in the manner and to
the addresses set forth in Section 15 of the Guaranty.

          13.  GENERAL PROVISIONS.

               13.1 SUCCESSORS AND ASSIGNS.  This Security Agreement shall bind
and inure to the benefit of the respective successors and assigns of Guarantor
and Bank; PROVIDED, HOWEVER, that Guarantor may not assign this Security
Agreement nor delegate any of its duties hereunder without Bank's prior written
consent and any prohibited assignment or delegation shall be absolutely void.
No consent by Bank to an assignment by Guarantor shall release Guarantor from
the Secured Obligations.  Bank reserves its right to sell, assign, transfer,
negotiate, or grant participations in all or any part of, or any interest in,
the rights and benefits hereunder pursuant to and in accordance with the
provisions of the Loan Agreement.  In connection therewith, Bank may disclose
all documents and information which Bank now or hereafter may have relating to

conflicts of law.

          15.  JUDICIAL REFERENCE.

               15.1 Other than (i) nonjudicial foreclosure and all matters in
connection therewith regarding security interests in real or personal property;
or (ii) the appointment of a receiver, or the exercise of other provisional
remedies (any and all of which may be initiated pursuant to applicable law),
each controversy, dispute or claim between the parties arising out of or
relating to this Security Agreement, which controversy, dispute or claim is not
settled in writing within thirty (30) days after the "Claim Date" (defined as
the date on which Guarantor or Bank gives written notice to the other that a
controversy, dispute or claim exists), will be settled by a reference proceeding
in California in accordance with the provisions of Section 638 ET SEQ. of the
California Code of Civil Procedure, or their successor section ("CCP"), which
shall constitute the exclusive remedy


                                          17
<PAGE>

for the settlement of any controversy, dispute or claim concerning this Security
Agreement, including whether such controversy, dispute or claim is subject to
the reference proceeding and except as set forth above, the parties waive their
rights to initiate any legal proceedings against each other in any court or
jurisdiction other than the Superior Court in the County where any real property
Collateral is located or Los Angeles County if none (the "Court").  The referee
shall be a retired Judge of the Court selected by mutual agreement of the
parties, and if they cannot so agree within forty-five (45) days after the Claim
Date, the referee shall be promptly selected by the Presiding Judge of the Court
(or his representative).  The referee shall be appointed to sit as a temporary
judge, with all of the powers for a temporary judge, as authorized by law, and
upon selection should take and subscribe to the oath of office as provided for
in Rule 244 of the California Rules of Court (or any subsequently enacted Rule).
Each party shall have one peremptory challenge pursuant to CCP Section 170.6.
The referee shall (a) be requested to set the matter for hearing within sixty
(60) days after the Claim Date and (b) try any and all issues of law or fact and
report a statement of decision upon them, if possible, within ninety (90) days
of the Claim Date.  Any decision rendered by the referee will be final, binding
and conclusive and judgment shall be entered pursuant to CCP Section 644 in any
court in the State of California having jurisdiction.  Any party may apply for a
reference proceeding at any time after thirty (30) days following notice to any
other party of the nature of the controversy, dispute or claim, by filing a
petition for a hearing and/or trial.  All discovery permitted by this Security
Agreement shall be completed no later than fifteen (15) days before the first
hearing date established by the referee.  The referee may extend such period in
the event of a party's refusal to provide requested discovery for any reason
whatsoever, including, without limitation, legal objections raised to such
discovery or unavailability of a witness due to absence or illness.  No party
shall be entitled to "priority" in conducting discovery.  Depositions may be
taken by either party upon seven (7) days written notice, and request for
production or inspection of documents shall be responded to within ten (10) days
after service.  All disputes relating to discovery which cannot be resolved by
the parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Superior Court is empowered to issue temporary and/or provisional
remedies, as appropriate.

               15.2 Except as expressly set forth in this Security Agreement,
the referee shall determine the manner in which the reference proceeding is
conducted including the time and place of all hearings, the order of
presentation of evidence, and all other questions that arise with respect to the
course of the reference proceeding.  All proceedings and hearings conducted
before the referee, except for trial, shall be conducted without a court
reporter except that when any party so requests, a court reporter will be used
at any hearing conducted before the referee.  The party making such a request
shall have the obligation to arrange for and pay for the court reporter.  The
costs of the court reporter at the trial shall be borne equally by the parties.

               15.3 The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable


                                          18
<PAGE>

as well as legal relief, to provide all temporary and/or provisional remedies
and to enter equitable orders that will be binding upon the parties.  The
referee shall issue a single judgment at the close of the reference proceeding
which shall dispose of all of the claims of the parties that are the subject of
the reference.  The parties hereto expressly reserve the right to contest or
appeal from the final judgment or any appealable order or appealable judgment
entered by the referee.  The parties hereto expressly reserve the right to
findings of fact, conclusions of laws, a written statement of decision, and the
right to move for a new trial or a different judgment, which new trial, if
granted, is also to be a reference proceeding under this provision.

               15.4 In the event that the enabling legislation which provides
for appointment of a referee is repealed (and no successor statute is enacted),
any dispute between the parties that would otherwise be determined by the
reference procedure herein described will be resolved and determined by
arbitration.  The arbitration will be conducted by a retired judge of the Court,
in accordance with the California Arbitration Act, Section 1280 through Section
1294.2 of the CCP as amended from time to time.  The limitations with respect to
discovery as set forth hereinabove shall apply to any such arbitration
proceeding.

       NOW THEREFORE, in consideration of the mutual promises, covenants,
conditions, representations, and warranties hereinafter set forth and for other
good and valuable consideration, the parties hereto mutually agree as follows:

       1.   DEFINITIONS AND CONSTRUCTION.

            (a)  DEFINITIONS.  All initially capitalized terms used but not

of Common Stock of Company in which Pledgor has an interest at any time while
this Agreement is in effect (collectively, the "SHARES");


                                          1
<PAGE>

                    (ii)   All of Pledgor's presently existing and hereafter

Company's capital stock and all rights represented thereby (the "OPTIONS"); and

                    (iii)  The proceeds of each of the foregoing, including any
and all dividends, cash, stock, instruments, and other property from time to

Loan Agreement) and the obligations of Pledgor hereunder.

                    "'33 ACT" means the Securities Act of 1933, as amended and
supplemented from time to time, and any successor statute, and any and all rules
promulgated in connection therewith.

               (b)  CONSTRUCTION.  Unless the context of this Agreement clearly
requires otherwise, references to the plural include the singular, references to
the singular include the plural, the part includes the whole, "including" is not
limiting, and "or" has the inclusive meaning represented by the phrase "and/or."
References in this Agreement to "determination" by Pledgee include reasonable
estimates (absent manifest error) by Pledgee, as applicable (in the case of
quantitative determinations) and reasonable beliefs (absent manifest error) by
Pledgee, as applicable (in the case of qualitative determinations).  The words
"hereof," "herein," "hereby," "hereunder," and similar terms in this Agreement
refer to this Agreement as a whole and not to any particular provision of this
Agreement.  Article, section, subsection, exhibit, and schedule references are
to this Agreement unless otherwise specified.

          2.   PLEDGE.  As security for the prompt and complete payment and
performance of the Secured Obligations, Pledgor hereby delivers, pledges, and
grants to Pledgee a continuing security interest in all of Pledgor's now-owned
or hereafter-acquired right, title, and interest in and to the Collateral.

          3.   CONTROL OF COLLATERAL.  Pledgor shall promptly deliver to Pledgee
any and all Certificated Securities comprising all or any portion of the
Collateral for Pledgee to hold pursuant to the terms hereof, and if such
Certificated Securities are in Registered Form, (i) such Certificated Securities
shall be endorsed in blank by an effective undated Endorsement, in form and
substance satisfactory to Pledgee in its sole and absolute discretion, or (ii)
Pledgor shall cause the Company or the Company's transfer agent to transfer such
Securities into the name of Pledgee and issue a replacement Security


                                          2
<PAGE>

Certificate evidencing the same in the name of Pledgee.  In the event that all
or any portion of the Collateral consists of Uncertificated Securities, Pledgor
shall cause the Company to enter into a control agreement with respect to such
Uncertificated Securities, in form and substance satisfactory to Pledgee in its
sole and absolute discretion.

          4.   FURTHER ASSURANCES.  Pledgor agrees that it shall cooperate with
Pledgee and shall execute and deliver, or cause to be executed and delivered, to
Pledgee all stock powers, proxies, assignments, financing statements,
instruments, control agreements and other documents, and shall take all further
action, at the expense of Pledgor, from time to time requested by Pledgee, in
order to maintain a continuing, first-priority, perfected security interest in
the Collateral in favor of Pledgee, and to enable Pledgee to exercise and
enforce its rights and remedies hereunder with respect to the Collateral, and
Pledgor agrees that it shall execute and deliver to Pledgee at Pledgee's request
any further applications, agreements, documents and instruments, and shall
perform any and all acts deemed necessary by Pledgee to carry into effect the
terms, conditions, and provisions of this Agreement and the transactions
connected herewith.  Should Pledgor fail to execute or deliver any such
applications, agreements, documents, financing statements and instruments, or to
perform any such acts, Pledgor acknowledges that Pledgee may execute and deliver
the same and perform such acts in the name of Pledgor and on its behalf as its
attorney-in-fact in accordance with Section 13.

          5.   PLEDGEE'S DUTIES.  Pledgee shall not have any duties with respect
to the Collateral other than the duty to use reasonable care if the Collateral
is in its possession.  In accordance with Section 9207 of the Code, Pledgee
shall be deemed to have used reasonable care if it observes substantially the
same standard of care with respect to the custody or preservation of the
Collateral as it observes with respect to similar assets owned by Pledgee.
Without limiting the generality of the foregoing, Pledgee shall be under no
obligation to take any steps necessary to preserve rights in the Collateral
against any other parties, to sell the same if it threatens to decline in value,
or to exercise any rights represented thereby (including rights with respect to
calls, conversions, exchanges, maturities, or tenders); PROVIDED, HOWEVER, that
Pledgee may, at its option, do so, and any and all expenses incurred in
connection therewith shall be for the account of Pledgor.

          6.   VOTING RIGHTS; DIVIDENDS; ETC.

               6.1  During the term of this Agreement, and as long as no Event
of Default is continuing:

                    (a)  Pledgor shall be entitled to exercise any and all
voting and other consensual rights pertaining to the Shares or any part thereof;
PROVIDED, HOWEVER, no vote shall be cast or any consent, waiver or ratification
given or any action taken which would violate or be inconsistent with the terms
of this Agreement, the Loan Agreement or any other instrument or agreement
referred to therein or herein, or which could have the effect of impairing the
value of the Collateral or any part thereof or the position or interest of
Pledgee therein.


                                          3
<PAGE>

                    (b)  Pledgor shall be entitled to receive and retain any and
all dividends and distributions paid in respect of the Shares not otherwise
prohibited by the Loan Agreement; PROVIDED, HOWEVER, that any and all:

                         (i)    dividends and distributions paid or payable
other than in cash in respect of, and any and all additional Shares or
instruments or other property received, receivable, or otherwise distributed in
respect of, or in exchange for, any Shares;

                         (ii)   dividends and distributions paid or payable in
cash in respect of any Shares in connection with a partial or total liquidation
or dissolution, merger, consolidation of the Company, or any exchange of stock,
conveyance of assets, or similar corporate reorganization; and

                         (iii)  cash paid with respect to, payable, or
otherwise distributed on redemption of, or in exchange for, any Shares,shall be
forthwith delivered to Pledgee to hold as Collateral and shall, if received by
Pledgor, be received in trust for the benefit of Pledgee, be segregated from the
other property or funds of Pledgor, and be forthwith delivered to Pledgee as
Collateral in the same form as so received (with any necessary endorsement),
and, if deemed appropriate by Pledgee, Pledgor shall take such actions,
including the actions described in Section 2, as Pledgee may require.

               6.2  Upon the occurrence of an Event of Default or if any amounts
shall be due and payable (whether by acceleration, maturity, or otherwise) under
any of the Secured Obligations, all rights of Pledgor to exercise the voting and
other consensual rights that it would otherwise be entitled to exercise pursuant
to Section 6.1(a) and to receive the dividends and distributions that it would
otherwise be authorized to receive and retain pursuant to Section 5.1(b) shall,
at Pledgee's option, cease, and all such rights shall, at Pledgee's option,
thereupon become vested in Pledgee, and Pledgee shall, at its option, thereupon
have the sole right to exercise such voting and other consensual rights and to
receive and hold as Collateral such dividends and interest payments.  Any
payments received by Pledgor contrary to the provisions of this Section 6.2
shall be held in trust by Pledgor for the benefit of Pledgee, shall be
segregated from other funds of Pledgor, and shall be promptly paid over to
Pledgee, with any necessary endorsement.

          7.   REPRESENTATIONS, WARRANTIES, AND COVENANTS.  In order to induce
Pledgee to enter into the Loan Agreement and make and continue to make Loans to
Pledgor, Pledgor hereby warrants, represents, and covenants that:

               7.1  There are no restrictions upon the transfer of any of the
Collateral to or by Pledgee and Pledgor is the sole beneficial owner of the
Collateral and has the right to pledge and grant a security interest in or
otherwise transfer such Collateral free of any encumbrances or rights of third
Persons.


                                          4
<PAGE>

               7.2  All of the Collateral is and shall remain free from all
Liens except as created hereby.  Pledgor shall not, without Pledgee's prior
written consent, sell or otherwise dispose of any of the Collateral.

               7.3  The execution and delivery of this Agreement, and the
completion of the actions described in Section 3, creates a valid, perfected and
first-priority security interest in the Collateral in favor of Pledgee, and all
actions necessary or desirable to such perfection have been duly taken.

               7.4  No authorization or other action by, and no notice to or
filing with, any Governmental Authority is required either:  (a) for the grant
by Pledgor of the security interest granted hereby or for the execution,
delivery, or performance of this Agreement by Pledgor; (b) for the perfection of
or exercise by Pledgee of its rights and remedies hereunder except as may be
required in connection with a disposition of the Collateral by laws affecting
the offering and sale of securities generally; or (c) for the exercise by
Pledgee of the voting or other rights provided for in this Agreement or the
remedies in respect of the Collateral pursuant to this Agreement except as may
be required in connection with a disposition of the Collateral by laws affecting
the offering and sale of securities generally.

               7.5  The pledge of the Collateral pursuant to this Agreement, and
the making of the loans in accordance with the terms of the Loan Agreement, does
not violate Regulation G, T, U, or X of the Board of Governors of the Federal
Reserve System.

               7.6  The Company presently has issued and outstanding One
Thousand Six Hundred (1,600) shares of Common Stock of which one hundred percent
(100%) is owned by Pledgor and they constitute, respectively, all of the capital
stock of Company and the Shares referenced herein.

               7.7  There are no presently existing Options.

               7.8  All of the outstanding Shares have been duly and validly
issued by the Company, and they are fully paid and nonassessable.

               7.9  Pledgor has made its own arrangements for keeping informed
of changes or potential changes affecting the Collateral (including, but not
limited to, rights to convert, rights to subscribe, payment of dividends,
reorganization or other exchanges, tender offers, and voting rights), and
Pledgor agrees that Pledgee shall not have any responsibility or liability for
informing Pledgor of any such changes or potential changes or for taking any
action or omitting to take any action with respect thereto.

               7.10 Pledgor shall at all times keep its books and records
concerning the Collateral at its chief executive office.  Pledgor shall not
change the location of its chief executive office without giving Pledgee at
least thirty (30) days' prior written notice thereof.


                                          5
<PAGE>

               7.11 Pledgor shall prevent the Company from issuing any
additional Shares or Options.

          8.   SHARE ADJUSTMENTS.  In the event that during the term of this
Agreement any reclassification, readjustment, or other change is declared or
made in the capital structure of any Company, Pledgor shall give Pledgee prompt
written notice thereof and all new substituted and additional shares or other
Securities, issued or issuable to Pledgor by reason of any such change or
exercise shall be subject to the security interest created hereby and Pledgor
shall as soon as practicable but in no event more than 10 days thereafter, take
all of the actions required under Section 3 with respect thereto.

          9.   OPTIONS.  In the event that during the term of this Agreement
Options shall be issued or exercised in connection with the Collateral, Pledgor
shall give Pledgee prompt written notice thereof and such Options acquired by
Pledgor shall be immediately assigned by Pledgor to Pledgee pursuant to an
assignment agreement in form and substance satisfactory to Pledgee in its sole
and absolute discretion, and all new shares or other Securities so acquired by
Pledgor shall also be subject to the security interest created hereby and
Pledgor shall as soon as practicable but in no event more than 10 days
thereafter, take all of the actions required under Section 3 with respect
thereto.

          10.  CONSENT.  Pledgor hereby consents that, from time to time, before
or after the occurrence or existence of any Event of Default with or without
notice to or assent from Pledgor, any other security at any time held by or
available to Pledgee for any of the Secured Obligations or any other security at
any time held by or available to Pledgee of any other person, firm, or
corporation secondarily or otherwise liable for any of the Secured Obligations,
may be exchanged, surrendered, or released and any of the Secured Obligations
may be changed, altered, renewed, extended, continued, surrendered, compromised,
waived, or released, in whole or in part, as Pledgee may see fit.  Pledgor shall
remain bound under this Agreement notwithstanding any such exchange, surrender,
release, alteration, renewal, extension, continuance, compromise, waiver, or
inaction, or extension of further credit.

          11.  EVENTS OF DEFAULT.  The occurrence of an Event of Default under
the Loan Agreement shall constitute an event of default ("EVENT OF DEFAULT")
under this Agreement.

          12.  REMEDIES UPON DEFAULT.

               12.1 Upon the occurrence of an Event of Default, Pledgee shall
have, in addition to any other rights given by law or in this Agreement, in the
Loan Agreement, or in any other agreement between Pledgee and Pledgor, all of
the rights and remedies with respect to the Collateral of a secured party under
the Code, and also shall have, without limitation, the following rights, which
Pledgor hereby agrees to be commercially reasonable:


                                          6
<PAGE>

                    (a)  to receive all amounts payable in respect of the
Collateral to Pledgor under Section 6.1(b) hereof;

                    (b)  to register all or any part of the Collateral on the
books of the Company in Pledgee's name or the name of its nominee or nominees;

                    (c)  to vote all or any part of the Shares (whether or not
transferred into the name of the Pledgee) in accordance with Section 6.2 hereof,
and give all consents, waivers and ratifications in respect of the Collateral
and otherwise act with respect thereto as though it were the outright owner
thereof; PLEDGOR HEREBY IRREVOCABLY CONSTITUTES AND APPOINTS PLEDGEE THE PROXY
AND ATTORNEY-IN-FACT OF PLEDGOR, COUPLED WITH AN INTEREST, WITH FULL POWER OF
SUBSTITUTION FOR ANY AND ALL OF SUCH PURPOSES;  WHICH PROXY AND POWER OF
ATTORNEY SHALL CONTINUE IN FULL FORCE AND EFFECT AND TERMINATE UPON THE EARLIER
TO OCCUR OF (a) UPON THE INDEFEASIBLE PAYMENT IN FULL OF THE SECURED
OBLIGATIONS, AND (b) TEN (10) YEARS FROM THE DATE HEREOF.

                    (d)  at any time or from time to time, to sell, assign and
deliver, or grant options to purchase, all or any part of the Collateral, or any
interest therein, at any public or private sale, without demand of performance,
advertisement or notice of intention to sell or of the time or place of sale or
adjournment thereof or to redeem or otherwise (all of which are hereby waived by
Pledgor), for cash, on credit or for other property, for immediate or future
delivery without any assumption of credit risk, and for such price or prices and
on such terms as the Pledgee in its absolute discretion may determine; PROVIDED,
that at least five (5) days notice of the time and place of any such sale shall
be given to Pledgor.  Pledgee shall not be obligated to make any such sale of
Collateral regardless of whether any such notice of sale has therefore been
given.  Pledgor hereby waives any other requirement of notice, demand, or
advertisement for sale, to the extent permitted by law.  Pledgor hereby waives
and releases to the fullest extent permitted by law any right or equity of
redemption with respect to the Collateral, whether before or after sale
hereunder, and all rights, if any, of marshalling the Collateral and any other
security for the Secured Obligations or otherwise.  At any such sale, unless
prohibited by applicable law, Pledgee may bid for and purchase all or any part
of the Collateral so sold free from any such right or equity of redemption.
Pledgee shall not be liable for failure to collect or realize upon any or all of
the Collateral or for any delay in so doing nor shall Pledgee be under any
obligation to take any action whatsoever with regard thereto;

                    (e)  to buy the Collateral, in its own name, or in the name
of a designee or nominee.  Pledgee shall have the right to execute any document
or form, in its name or in the name of the Pledgor, that may be necessary or
desirable in connection with such sale of the Collateral.

                    (f)  to sell all or any part of the Collateral by a private
placement, restricting bidders and prospective purchasers to those who will
represent and agree that they are purchasing for investment only and not for
distribution.  In so doing,


                                          7
<PAGE>

Pledgee may solicit offers to buy the Collateral, or any part of it for cash,
from a limited number of investors deemed by Pledgee, in its reasonable
judgment, to be responsible parties who might be interested in purchasing the
Collateral.  If Pledgee shall solicit such offers from not less than four (4)
such investors, then the acceptance by Pledgee of the highest offer obtained
therefore shall be deemed to be a commercial reasonable method of disposition of
such Collateral, even though the sales price established and/or obtained may be
substantially less than the price that would be obtained pursuant to a public
offering.  Notwithstanding the foregoing, should Pledgee determine that, prior
to any public offering of any securities contained in the Collateral, such
securities should be registered under the '33 Act and/or registered or qualified
under any other federal or state law, and that such registration and/or
qualification is not practical, Pledgor agrees that it will be commercially
reasonable if a private sale is arranged so as to avoid a public offering even
if offers are solicited from fewer than four (4) investors, and even though the
sales price established and/or obtained may be substantially less than the price
that would be obtained pursuant to a public offering.

          13.  PLEDGEE AS PLEDGOR'S ATTORNEY-IN FACT.  Pledgor hereby
irrevocably appoints Pledgee as its attorney-in-fact, coupled with an interest,
(i) to arrange for the register, at any time after the occurrence of an Event of
Default, of the Collateral on the books of the Company to the name of Pledgee or
to the name of Pledgee's nominee and (ii) to receive, endorse and collect all
instruments made payable to Pledgor of any dividend, distribution or other
payment on account of the Collateral, or any part thereof, and to give full
discharge for the same and to execute and file governmental notifications and
reporting forms.  Pledgor hereby further authorizes Pledgee to perform any and
all acts which Pledgee deems necessary for the protection and preservation of
the Collateral or of the value of Pledgee's security interest therein, including
but not limited to receiving income thereon as additional security hereunder,
and all expenses paid or incurred by Pledgee in connection therewith shall
constitute Bank Expenses.  Pledgor hereby further grants to Pledgee a power of
attorney coupled with an interest to execute all agreements, forms,
applications, documents and instruments and to take all actions and do all
things as could be executed, taken, or done by Pledgor in connection with the
protection and preservation of the Collateral or this Agreement.  This power of
attorney is irrevocable and authorizes Pledgee to act for Pledgor in connection
with the matters described herein without notice to or demand upon Pledgor.

          14.  GENERAL PROVISIONS.

               14.1 CUMULATIVE REMEDIES; NO PRIOR RECOURSE TO COLLATERAL.  The
enumeration herein of Pledgee's rights and remedies is not intended to be
exclusive, and such rights and remedies are in addition to and not by way of
limitation of any other rights or remedies that the Pledgee may have under the
Loan Agreement, the Loan Documents, the Code, or other applicable law.  Pledgee
shall have the right, in its sole discretion, to determine which rights and
remedies are to be exercised and in which order.  The exercise of one right or
remedy shall not preclude the exercise of any others, all of which shall be
cumulative.

<PAGE>

               14.2 NO IMPLIED WAIVERS.  No act, failure, or delay by Pledgee
shall constitute a waiver of any of its rights and remedies.  No single or
partial waiver by Pledgee of any provision of this Agreement or any other Loan
Document, or of a breach or default hereunder or thereunder, or of any right or
remedy which the Pledgee may have, shall operate as a waiver of any other
provision, breach, default, right, or remedy or of the same provision, breach,
default, right, or remedy on a future occasion.  No waiver by Pledgee shall
affect its rights to require strict performance of this Agreement.

               14.3 NOTICES.  All notices or demands by any party hereto to the
other party and relating to this Agreement shall be sent in accordance with the
terms of Section 9.1 of the Loan Agreement.

               14.4 SUCCESSORS AND ASSIGNS.  This Agreement shall bind the
successors and assigns of Pledgor, and shall inure to the benefit of the
successors and assigns of Pledgee; PROVIDED, HOWEVER, that Pledgor may not
assign this Agreement nor delegate any of its duties hereunder without Pledgee's
prior written consent and any prohibited assignment shall be absolutely void.
Pledgee may assign this Agreement and its rights and duties hereunder and no
consent or approval by Pledgor is required in connection with any such
assignment.  Pledgee reserves the right to sell, assign, transfer, negotiate, or
grant participations in all or any part of, or any interest in Pledgee's rights
and benefits hereunder.  In connection with any such assignment or
participation, Pledgee may disclose all documents and information which Pledgee
now or hereafter may have relating to Pledgor or Pledgor's business to any
prospective or actual Transferee, subject to the terms of Section 9.5(e) of the
Loan Agreement.

               14.5 EXHIBITS AND SCHEDULES.  All of the exhibits and schedules
attached hereto shall be deemed incorporated by reference.

               14.6 NO PRESUMPTION AGAINST ANY PARTY.  Neither this Agreement
nor any uncertainty or ambiguity herein shall be construed or resolved against
Pledgor or Pledgee, whether under any rule of construction or otherwise.  On the
contrary, this Agreement has been reviewed by each of the parties and their
counsel and shall be construed and interpreted according to the ordinary meaning
of the words used so as to accomplish fairly the purposes and intentions of all
parties hereto.

               14.7 SECTION HEADINGS.  Headings and numbers have been set forth
herein for convenience only.  Unless the contrary is compelled by the context,
everything contained in each section applies equally to this entire Agreement.

               14.8 SEVERABILITY OF PROVISIONS.  If any provision of this
Agreement is for any reason held to be invalid, illegal or unenforceable in any
respect, that provision shall not affect the validity, legality or
enforceability of any other provision of this Agreement.

               14.9 ENTIRE AGREEMENT; AMENDMENTS AND WAIVERS.  This Agreement
constitutes the entire agreement between Pledgor and Pledgee pertaining to the
subject


                                          9
<PAGE>

matter contained herein.  Any provision of this Agreement may be amended or
waived if, but only if, such amendment or waiver is in writing and is signed by
the party asserted to be bound thereby, and then such amendment or waiver shall
be effective only in the specific instance and specific purpose for which given.

               14.10     COUNTERPARTS; TELEFACSIMILE EXECUTION.  This Agreement
may be executed in any number of counterparts and by different parties on
separate counterparts, each of which, when executed and delivered, shall be
deemed to be an original, and all of which, when taken together, shall
constitute but one and the same Agreement.  Delivery of an executed counterpart
of this Agreement by telefacsimile shall be equally as effective as delivery of
a manually executed counterpart of this Agreement.  Any party delivering an
executed counterpart of this Agreement by telefacsimile also shall deliver a
manually executed counterpart of this Agreement but the failure to deliver a
manually executed counterpart shall not affect the validity, enforceability, and
binding effect of this Agreement.

               14.11     TERMINATION BY PLEDGEE.  After termination of the Loan
Agreement and when Pledgee has received payment and performance, in full, of the
Secured Obligations, Pledgee shall execute and deliver to Pledgor a termination
of all of the security interests granted by Pledgor hereunder and, to the extent
they have been delivered to Pledgee and not disposed of in accordance with this
Agreement, certificates evidencing the Shares.

          15.  GOVERNING LAW; JUDICIAL REFERENCE.

               15.1 GOVERNING LAW.  This Agreement shall be deemed to have been
made in the State of California and the validity, construction, interpretation,
and enforcement hereof, and the rights of the parties hereto, shall be
determined under, governed by, and construed in accordance with the internal
laws of the State of California, without regard to principles of conflicts of
law.

               15.2 JUDICIAL REFERENCE.

                    (a)  Other than (i) nonjudicial foreclosure and all matters
in connection therewith regarding security interests in real or personal
property; or (ii) the appointment of a receiver, or the exercise of other
provisional remedies (any and all of which may be initiated pursuant to
applicable law), each controversy, dispute or claim between the parties arising
out of or relating to this Agreement, which controversy, dispute or claim is not
settled in writing within thirty (30) days after the "CLAIM DATE" (defined as
the date on which a party subject to this Agreement gives written notice to all
other parties that a controversy, dispute or claim exists), will be settled by a
reference proceeding in California in accordance with the provisions of Section
638 ET SEQ. of the California Code of Civil Procedure, or their successor
section ("CCP"), which shall constitute the exclusive remedy for the settlement
of any controversy, dispute or claim concerning this Agreement, including
whether such controversy, dispute or claim is subject to the reference
proceeding and except as set forth above, the parties waive their rights to
initiate any legal proceedings against each other in any court or jurisdiction
other than the Superior Court in the County


                                          10
<PAGE>

where the Real Property, if any, is located or Los Angeles County if none (the
"COURT").  The referee shall be a retired Judge of the Court selected by mutual
agreement of the parties, and if they cannot so agree within forty-five (45)
days after the Claim Date, the referee shall be promptly selected by the
Presiding Judge of the Court (or his representative).  The referee shall be
appointed to sit as a temporary judge, with all of the powers for a temporary
judge, as authorized by law, and upon selection should take and subscribe to the
oath of office as provided for in Rule 244 of the California Rules of Court (or
any subsequently enacted Rule).  Each party shall have one peremptory challenge
pursuant to CCP Section 170.6.  The referee shall (a) be requested to set the
matter for hearing within sixty (60) days after the date of selection of the
referee and (b) try any and all issues of law or fact and report a statement of
decision upon them, if possible, within ninety (90) days of the Claim Date.  Any
decision rendered by the referee will be final, binding and conclusive and
judgment shall be entered pursuant to CCP Section 644 in any court in the State
of California having jurisdiction.  Any party may apply for a reference
proceeding at any time after thirty (30) days following notice to any other
party of the nature of the controversy, dispute or claim, by filing a petition
for a hearing and/or trial.  All discovery permitted by this Agreement shall be
completed no later than fifteen (15) days before the first hearing date
established by the referee.  The referee may extend such period in the event of
a party's refusal to provide requested discovery for any reason whatsoever,
including, without limitation, legal objections raised to such discovery or
unavailability of a witness due to absence or illness.  No party shall be
entitled to "priority" in conducting discovery.  Depositions may be taken by
either party upon seven (7) days written notice, and request for production or
inspection of documents shall be responded to within ten (10) days after
service.  All disputes relating to discovery which cannot be resolved by the
parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Superior Court is empowered to issue temporary and/or provisional
remedies, as appropriate.

                    (b)  Except as expressly set forth in this Agreement, the
referee shall determine the manner in which the reference proceeding is
conducted including the time and place of all hearings, the order of
presentation of evidence, and all other questions that arise with respect to the
course of the reference proceeding.  All proceedings and hearings conducted
before the referee, except for trial, shall be conducted without a court
reporter except that when any party so requests, a court reporter will be used
at any hearing conducted before the referee.  The party making such a request
shall have the obligation to arrange for and pay for the court reporter.  The
costs of the court reporter at the trial shall be borne equally by the parties.

                    (c)  The referee shall be required to determine all issues
in accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties.  The referee shall issue a single judgment at the
close of the reference proceeding which shall dispose of all of the claims of
the parties that are the subject of the reference.  The parties hereto expressly
reserve the 


                                          11
<PAGE>

right to contest or appeal from the final judgment or any appealable order or 
appealable judgment entered by the referee.  The parties hereto expressly 
reserve the right to findings of fact, conclusions of laws, a written 
statement of decision, and the right to move for a new trial or a different 
judgment, which new trial, if granted, is also to be a reference proceeding 
under this provision.

                    (d)  In the event that the enabling legislation which
provides for appointment of a referee is repealed (and no successor statute is
enacted), any dispute between the parties that would otherwise be determined by
the reference procedure herein described will be resolved and determined by
arbitration.  The arbitration will be conducted by a retired judge of the Court,
in accordance with the California Arbitration Act, Section 1280 through Section
1294.2 of the CCP as amended from time to time.  The limitations with respect to
discovery as set forth hereinabove shall apply to any such arbitration
proceeding.

          IN WITNESS WHEREOF, the parties have executed this Agreement on the
date first written above.

          THIS COLLATERAL ASSIGNMENT OF TRANSACTION DOCUMENTS (this
"ASSIGNMENT") has been executed and delivered as of July 3, 1997, by and between
PROSPECT MEDICAL SYSTEMS, INC., a Delaware corporation ("ASSIGNOR"), and
IMPERIAL BANK, a California banking corporation ("BANK"), with reference to the
following facts:

                                   R E C I T A L S

          B.   Assignor is contemporaneously herewith executing that certain
Continuing Guaranty, dated as of July 3, 1997, in favor of Bank (as the same may

"GUARANTY") pursuant to which Assignor guarantees the Guaranteed Obligations (as
defined in the Guaranty), including, without limitation, all obligations,
indebtedness and liabilities owed by Prospect Medical Holdings, Inc., a Delaware
corporation ("BORROWER") to Bank under that certain Revolving Credit Agreement,
dated as of July 3, 1997 (as the same may be amended, restated, supplemented or
otherwise modified from time to time, the "LOAN AGREEMENT").

          C.   Assignor has executed and delivered that certain Security
Agreement, dated as of even date with the Guaranty ("SECURITY AGREEMENT"), in
order to secure the Guaranteed Obligations.

          D.   Assignor has agreed to execute and deliver this Assignment to
Bank in order to supplement the terms of the Security Agreement with respect to
the Transaction Documents (as hereinafter defined).

          E.   Assignor is a wholly-owned subsidiary of Borrower which will
directly and materially benefit from the Loans made by Bank to Borrower under
the Loan Agreement, and Assignor acknowledges that Bank would not enter into the
Loan Agreement absent Assignor's agreements under the Guaranty, the Security
Agreement and hereunder.

                                  A G R E E M E N T

          In consideration of the premises and the mutual agreements herein set

          2.   ASSIGNMENT.  As additional security for the Guaranteed
Obligations, Assignor hereby collaterally assigns and transfers to Bank, and
acknowledges that pursuant to the Security Agreement Assignor has granted to

interest in and to the following documents (collectively, the "TRANSACTION
DOCUMENTS"):

and Physician Group;

                    (b)  Assignable Option Agreement, dated as of June 5, 1996,

Statements with respect thereto ("PHYSICIAN GROUP SECURITY AGREEMENT").

               2.2  RIGHTS AND REMEDIES.  All of the rights, benefits, remedies,
privileges and claims of Assignor with respect to the Transaction Documents
(collectively, the "RIGHTS AND REMEDIES"), including, without limitation, (i)
all rights to monies or payments owing to Assignor under the Transaction
Documents, and any and all security therefor and for all other obligations owing
to Assignor thereunder, (ii) any right that Assignor may have to indemnification
under the Transaction Documents, (iii) all Rights and Remedies of Assignor with
respect to any breach of the representations, warranties and covenants set forth
in the Purchase Agreement, and (iv) the proceeds thereof (the Transaction
Documents and the Rights and Remedies are collectively referred to herein as,
the "COLLATERAL").

          3.   RIGHT AND REMEDIES GENERALLY.  Prior to the occurrence of a
breach or default of any of the agreements, covenants and obligations of
Assignor under the Guaranty (a "DEFAULT"), Assignor will enforce all of its
Rights and Remedies diligently and in good faith.  Effective from and after the
occurrence of a Default, Assignor hereby irrevocably authorizes and empowers
Bank, in Bank's own discretion, to assert as Bank may deem proper, either
directly or on behalf of Assignor, any of the Rights and Remedies which Assignor
may from time to time have under the Transaction Documents, and to receive and
collect all damages, awards and other monies resulting therefrom and to apply
the same on account of any of the Guaranteed Obligations.

          4.   FURTHER ASSURANCES.  Assignor shall execute and deliver to Bank
concurrently with Assignor's execution of this Assignment, and from time to time
at the request of Bank, all financing statements, continuation financing
statements, fixture filings,


                                          2
<PAGE>

security agreements, chattel mortgages, assignments, and all other documents
that Bank may request, in form satisfactory to Bank, to perfect and maintain
perfected Bank's security interests in the Collateral and in order to consummate
fully all of the transactions contemplated by this Assignment.

          5.   TRANSACTION DOCUMENTS.  Concurrent herewith, Assignor is
delivering to Bank possession of the original Transaction Documents, together
with any and all amendments thereto, as in effect on the date hereof, including
the Note and Physician Group Security Agreement, duly endorsed to Bank pursuant
to an allonge in form and substance satisfactory to Bank, to hold in accordance
with the terms of the Security Agreement until the Security Agreement is
terminated in accordance with its terms.

          6.   ATTORNEY-IN-FACT.  Assignor hereby irrevocably makes,
constitutes, and appoints Bank (and Bank's officers, employees, or agents) as
Assignor's true and lawful agent and attorney-in-fact for the purposes of
enabling Bank or its agent(s) after the occurrence of a Default to (a) assert
such Rights and Remedies and to collect such damages, awards and other monies
and to apply them in the manner set forth hereinabove, and (b) to sign the name
of Assignor on any documents which need to be executed, recorded, or filed, and
to do any and all things necessary in the name and on behalf of Assignor in
order to protect Bank's interests in the Transaction Documents.  Assignor agrees
that neither Bank, nor any of its designers or attorneys-in-fact, will be liable
for any act of commission or omission, or for any error of judgment or mistake
of fact or law with respect to the exercise of the power of attorney granted
under this Section 6, other than as a result of its or their gross negligence or
wilful misconduct.  The power of attorney granted under this Section 6 is
coupled with an interest and shall be irrevocable until all of the Guaranteed
Obligations have been paid in full, the Guaranty terminated, and Assignor's
duties under this Assignment have been discharged in full.

          7.   MODIFICATION OF RIGHTS AND REMEDIES.  Assignor shall keep Bank
informed of all circumstances bearing upon the Rights and Remedies and shall
immediately provide Bank with copies of any notices delivered to Assignor in
connection with the Transaction Documents.  Assignor shall also provide Bank
with a copy of any notice sent by Assignor in connection with the Transaction
Documents, concurrently with the sending of any such notice.  Assignor shall not
waive, amend, alter or modify any of the Rights and Remedies in any material
respect without the prior written consent of Bank.  Assignor shall not, without
Bank's prior written consent, amend, alter, modify or terminate any of the
Transaction Documents, or waive any of the provisions thereof, or do or permit
any act in contravention thereof.

          8.   ASSIGNOR TO REMAIN LIABLE.  Notwithstanding the foregoing,

understanding between the parties with respect to the subject matter hereof and
supersedes all prior agreements, consents and understandings relating to such

          14.  JUDICIAL REFERENCE.

               14.1   REFERENCE PROCEEDING.  Other than (i) nonjudicial
foreclosure and all matters in connection therewith regarding security interests
in real or personal property; or (ii) the appointment of a receiver, or the
exercise of other provisional remedies (any and all of which may be initiated
pursuant to applicable law), each controversy, dispute or claim between the
parties arising out of or relating to this Assignment, which controversy,
dispute or claim is not settled in writing within thirty (30) days after the
"CLAIM DATE" (defined as the date on which either Assignor or Bank gives written
notice to the other that a controversy, dispute or claim exists), will be
settled by a reference proceeding in California in accordance with the
provisions of Section 638 ET SEQ. of the California Code of Civil Procedure, or
their successor section ("CCP"), which shall constitute the exclusive remedy for
the settlement of any controversy, dispute or claim


                                          4
<PAGE>

concerning this Assignment, including whether such controversy, dispute or claim
is subject to the reference proceeding and except as set forth above, the
parties waive their rights to initiate any legal proceedings against each other
in any court or jurisdiction other than the Superior Court in Los Angeles County
(the "COURT").  The referee shall be a retired Judge of the Court selected by
mutual agreement of the parties, and if they cannot so agree within forty-five
(45) days after the Claim Date, the referee shall be promptly selected by the
Presiding Judge of the Court (or his representative).  The referee shall be
appointed to sit as a temporary judge, with all of the powers for a temporary
judge, as authorized by law, and upon selection should take and subscribe to the
oath of office as provided for in Rule 244 of the California Rules of Court (or
any subsequently enacted Rule).  Each party shall have one peremptory challenge
pursuant to CCP Section 170.6.  The referee shall (a) be requested to set the
matter for hearing within sixty (60) days after the date of selection of the
referee and (b) try any and all issues of law or fact and report a statement of
decision upon them, if possible, within ninety (90) days of the Claim Date.  Any
decision rendered by the referee will be final, binding and conclusive and
judgment shall be entered pursuant to CCP Section 644 in any court in the State
of California having jurisdiction.  Any party may apply for a reference
proceeding at any time after thirty (30) days following notice to any other
party of the nature of the controversy, dispute or claim, by filing a petition
for a hearing and/or trial.  All discovery permitted by this Assignment shall be
completed no later than fifteen (15) days before the first hearing date
established by the referee.  The referee may extend such period in the event of
a party's refusal to provide requested discovery for any reason whatsoever,
including, without limitation, legal objections raised to such discovery or
unavailability of a witness due to absence or illness.  No party shall be
entitled to "priority" in conducting discovery.  Depositions may be taken by
either party upon seven (7) days written notice, and request for production or
inspection of documents shall be responded to within ten (10) days after
service.  All disputes relating to discovery which cannot be resolved by the
parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Court is empowered to issue temporary and/or provisional remedies,
as appropriate.

               14.2   MANNER OF REFERENCE PROCEEDING.  Except as expressly set
forth in this Assignment, the referee shall determine the manner in which the
reference proceeding is conducted including the time and place of all hearings,
the order of presentation of evidence, and all other questions that arise with
respect to the course of the reference proceeding.  All proceedings and hearings
conducted before the referee, except for trial, shall be conducted without a
court reporter except that when any party so requests, a court reporter will be
used at any hearing conducted before the referee.  The party making such a
request shall have the obligation to arrange for and pay for the court reporter.
The costs of the court reporter at the trial shall be borne equally by the
parties.

               14.3   DUTIES OF REFEREE.  The referee shall be required to
determine all issues in accordance with existing case law and the statutory laws
of the State of California.  The rules of evidence applicable to proceedings at
law in the State of California will be applicable to the reference proceeding.
The referee shall be empowered to enter equitable as well as legal relief, to
provide all temporary and/or provisional remedies and


                                          5
<PAGE>

to enter equitable orders that will be binding upon the parties.  The referee
shall issue a single judgment at the close of the reference proceeding which
shall dispose of all of the claims of the parties that are the subject of the
reference.  The parties hereto expressly reserve the right to contest or appeal
from the final judgment or any appealable order or appealable judgment entered
by the referee.  The parties hereto expressly reserve the right to findings of
fact, conclusions of laws, a written statement of decision, and the right to
move for a new trial or a different judgment, which new trial, if granted, is
also to be a reference proceeding under this provision.

               14.4   ARBITRATION ALTERNATIVE.  In the event that the enabling
legislation which provides for appointment of a referee is repealed (and no
successor statute is enacted), any dispute between the parties that would
otherwise be determined by the reference procedure herein described will be
resolved and determined by arbitration.  The arbitration will be conducted by a
retired judge of the Court, in accordance with the California Arbitration Act,
Section 1280 through Section 1294.2 of the CCP as amended from time to time.
The limitations with respect to discovery as set forth hereinabove shall apply
to any such arbitration proceeding.

     EXECUTED as of the date first above written.

Collateral as follows:

                         (i)    Manager shall give Physician Group and each
holder of a security interest in the Collateral who has filed with Manager a

<PAGE>

                         (iii)  If the disposition is to be a public sale,
Manager shall also give notice of the time and place of said sale by publishing
a notice at least five (5) calendar days before the date of the sale in a
newspaper of general circulation, if one exists, in the county in which the sale
is to be held;

                    (e)  Manager may, in its own name, or in the name of a
designee or nominee, credit bid and purchase at any public sale;

                    (f)  Physician Group shall pay all Expenses; and

                    (g)  Any portion of the Secured Obligations which remains
unpaid after disposition of the Collateral as provided above shall be paid
immediately by Physician Group.  Any excess which exists after disposition of
the Collateral and payment in full of the Secured Obligations shall be returned
promptly, without interest and subject to the rights of third persons, to

       (m)  JUDICIAL REFERENCE.  Other than (i) nonjudicial foreclosure and
all matters in connection therewith regarding security interests in real or
personal property; or (ii) the appointment of a receiver, or the exercise of
other provisional remedies (any and all of which may be initiated pursuant to
applicable law), each controversy, dispute or claim between the parties arising
out of or relating to this Agreement, which controversy, dispute or claim is not
settled in writing within thirty (30) days after the "CLAIM DATE" (defined as
the date on which a party subject to the Agreement gives written notice to all
other parties that a controversy, dispute or claim exists), will be settled by a
reference proceeding in California in accordance with the provisions of Section
638 ET SEQ. of the California Code of Civil Procedure, or their successor
section ("CCP"), which shall constitute the exclusive remedy for the settlement
of any controversy, dispute or claim concerning this Agreement, including
whether such controversy, dispute or claim is subject to the reference
proceeding and except as set forth above, the parties waive their rights to
initiate any legal proceedings against each other in any court or jurisdiction
other than the Superior Court in the County where the Real Property, if any, is
located or Los Angeles County if none (the "Court").  The referee shall be a
retired Judge of the Court selected by mutual agreement of the parties, and if
they cannot so agree within forty-five (45) days after the Claim Date, the
referee shall be promptly selected by the Presiding Judge of the Court (or his
representative).  The referee shall be appointed to sit as a temporary judge,
with all of the powers for a temporary judge, as authorized by law, and upon
selection should take and subscribe to the oath of office as provided for in
Rule 244 of the California Rules of Court (or any subsequently enacted Rule).
Each party shall have one peremptory challenge pursuant to CCP Section 170.6.
The referee shall (a) be requested to set the matter for hearing within sixty
(60) days after the Claim Date and (b) try any and all issues of law or fact and
report a statement of decision upon them, if possible, within ninety (90) days
of the Claim Date.  Any decision rendered by the referee will be final, binding
and conclusive and judgment shall be entered pursuant to CCP Section 644 in any
court in the State of California having jurisdiction.  Any party may apply for a
reference proceeding at any time after thirty (30) days following notice to any
other party of the nature of the controversy, dispute or claim, by filing a
petition for a hearing and/or trial.  All discovery permitted by this Agreement
shall be completed no later than fifteen (15) days before the first hearing date
established by the referee.  The referee may extend such period in the event of
a party's refusal to provide requested discovery for any reason whatsoever,
including, without limitation, legal objections raised to such discovery or
unavailability of a witness due to absence or illness.  No party shall be
entitled to "priority" in conducting discovery.  Depositions may be taken by
either party upon seven (7) days written notice, and request for production or
inspection of documents shall be responded to within ten (10) days after
service.  All disputes relating to discovery which cannot be resolved by the
parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Superior Court is empowered to issue temporary and/or provisional
remedies, as appropriate.

       Except as expressly set forth in this Agreement, the referee shall
determine the manner in which the reference proceeding is conducted including
the time and place of all hearings, the order of presentation of evidence, and
all other questions that arise with


                                          11
<PAGE>

respect to the course of the reference proceeding.  All proceedings and
hearings conducted before the referee, except for trial, shall be conducted
without a court reporter except that when any party so requests, a court
reporter will be used at any hearing conducted before the referee.  The party
making such a request shall have the obligation to arrange for and pay for the
court reporter.  The costs of the court reporter at the trial shall be borne
equally by the parties.

       The referee shall be required to determine all issues in accordance
with existing case law and the statutory laws of the State of California.  The
rules of evidence applicable to proceedings at law in the State of California
will be applicable to the reference proceeding.  The referee shall be empowered
to enter equitable as well as legal relief, to provide all temporary and/or
provisional remedies and to enter equitable orders that will be binding upon the
parties.  The referee shall issue a single judgment at the close of the
reference proceeding which shall dispose of all of the claims of the parties
that are the subject of the reference.  The parties hereto expressly reserve the
right to contest or appeal from the final judgment or any appealable order or
appealable judgment entered by the referee.  The parties hereto expressly
reserve the right to findings of fact, conclusions of laws, a written statement
of decision, and the right to move for a new trial or a different judgment,
which new trial, if granted, is also to be a reference proceeding under this
provision.

       In the event that the enabling legislation which provides for
appointment of a referee is repealed (and no successor statute is enacted), any
dispute between the parties that would otherwise be determined by the reference
procedure herein described will be resolved and determined by arbitration.  The
arbitration will be conducted by a retired judge of the Court, in accordance
with the California Arbitration Act, Section 1280 through Section 1294.2 of the
CCP as amended from time to time.  The limitations with respect to discovery as
set forth hereinabove shall apply to any such arbitration proceeding.

       IN WITNESS WHEREOF, the parties hereto have executed this Agreement as
of the date and year first above written.

with respect to Common Stock or any other security that is not listed on a 
national securities exchange or traded on the over-the-counter market or 
quoted on NASDAQ, and (ii) the average of the daily closing prices for the

directed by agreement of the Company and such holders, such firms, in their sole
discretion, shall choose another investment banking firm independent of the
Company and such holders, which firm shall make the determination and render an
opinion as promptly as practicable.  In either case, the determination so made
shall be conclusive and binding on the Company and such holders.  The fees and
expenses of any such determination made by any and all such independent
investment banking firms shall be paid by the Company.  If there is more than
one holder of Warrants, and/or Warrant Shares entitled to a determination of
Fair Value in any particular instance, each action to be taken by the holders of
such Warrants and/or Warrant Shares under this Section shall be taken by a
majority in interest of such holders


                                          3
<PAGE>

and the action taken by such majority (including as to any mutual agreement with
the Company with respect to Fair Value and as to any selection of investment
banking firms) shall be binding upon all such holders.  In the case of a
determination of the Fair Value per share of Common Stock, the Company and such
holders shall not take into consideration, and shall instruct all such
investment banking firms not to take into consideration, any premium for shares
representing control of the Company, any discount for any minority interest
therein or any restrictions on transfer under applicable federal and state

otherwise in connection with, such Warrant Shares.  For purposes of Section 11,

Warrant Shares and other securities issuable pursuant to the Warrants.

respect of which the Warrant is exercised.

     3.   FORM OF PAYMENT OF EXERCISE PRICE.  Anything contained herein to the

(c) by the cancellation of any indebtedness owed by the Company and/or any
subsidiaries of the Company to the Warrantholder, and/or (d) by the surrender to

     4.   CASHLESS EXERCISE/CONVERSION.  In lieu of exercising this Warrant as

exercise of this Warrant minus the aggregate Exercise Price of such shares by
(B) the Fair Value of one such share.

     5.   CERTIFICATES FOR WARRANT SHARES; NEW WARRANT.  The Company agrees that

conversion) in accordance with the terms of this Warrant.  Certificates for the
Warrant Shares shall be delivered to the Warrantholders within a reasonable

the Company at the time of exercise.

     6.   ADJUSTMENT OF EXERCISE PRICE, NUMBER OF SHARES AND NATURE OF
SECURITIES ISSUABLE UPON EXERCISE OF WARRANTS.

          (a)  EXERCISE PRICE:  ADJUSTMENT OF NUMBER OF SHARES.  The Exercise
Price shall be subject to adjustment from time to time as hereinafter provided.
Upon each adjustment of the Exercise Price, the Warrantholders shall thereafter
be entitled to purchase, at the Exercise Price resulting from such adjustment, a
number of shares determined by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number


                                          5
<PAGE>

of shares purchasable pursuant hereto immediately prior to such adjustment and
dividing the product thereof by the Exercise Price resulting from such
adjustment.

          (b)  ADJUSTMENT OF EXERCISE PRICE UPON ISSUANCE OF COMMON STOCK.  If
and whenever after the date hereof the Company shall issue or sell Additional
Shares of Common Stock without consideration or for a consideration per share
less than the Current Market Price or the Exercise Price then in effect
immediately prior to the issuance or sale of such shares, then the Exercise
Price in effect immediately prior to such issuance or sale of such shares shall
be reduced to a number which shall be calculated by dividing (A) an amount equal
to the sum of (1) the number of shares of Common Stock outstanding immediately
prior to such issue or sale MULTIPLIED BY the then existing Exercise Price PLUS
(2) the aggregate consideration, if any, received by the Company upon such issue
or sale, by (B) the total number of shares of Common Stock outstanding
immediately after such issue or sale.

               No adjustment of the Exercise Price, however, shall be made in an
amount less than $.01 per share, but any such lesser adjustment shall be carried
forward and shall be made at the time and together with the next subsequent
adjustment which, together with any adjustments so carried forward, shall amount
to $.01 per share or more.

               The provisions of this Section 6(b) shall not apply to any
Additional Shares of Common Stock which are distributed to holders of Common
Stock pursuant to a stock split for which an adjustment is provided for under
Section 6(f).

          (c)  FURTHER PROVISIONS FOR ADJUSTMENT OF EXERCISE PRICE UPON ISSUANCE
OF ADDITIONAL SHARES OF COMMON STOCK AND CONVERTIBLE SECURITIES.  For purposes
of Section 6(b), the following provisions shall also be applicable:

               (i)    In case at any time on or after the date hereof, the
Company shall declare any dividend, or authorize any other distribution, upon
any stock of the Company of any class, payable in Additional Shares of Common
Stock or by the issuance of Convertible Securities, such declaration or
distribution shall be deemed to have been issued or sold (as of the record date)
without consideration and shall thereby cause an adjustment in the Exercise
Price as required by Section 6(b).

               (ii)   (A)     In case at any time on or after the date hereof,
the Company shall in any manner issue or sell any Convertible Securities,
whether or not the rights to exchange or convert thereunder are immediately
exercisable, there shall be determined the price per share for which Additional
Shares of Common Stock are issuable upon the conversion or exchange thereof,
such determination to be made by dividing (a) the total amount received or
receivable by the Company as consideration for the issue or sale of such
Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the conversion or exchange
thereof by (b) the maximum aggregate number of Additional Shares of Common Stock
issuable upon conversion or exchange of all such Convertible Securities for such
minimum aggregate


                                          6
<PAGE>

amount of additional consideration; and such issue or sale shall be deemed to be
an issue or sale for cash (as of the date of issue or sale of such Convertible
Securities) of such maximum number of Additional Shares of Common Stock at the
price per share so determined, and shall thereby cause an adjustment in the
Exercise Price, if such an adjustment is required by Section 6(b) hereof.

                      (B)     If such Convertible Securities shall by their
terms provide for an increase or increases, with the passage of time, in the
amount of additional consideration, if any, payable to the Company, or in the
rate of exchange upon the conversion or exchange thereof, the adjusted Exercise
Price shall, upon any such increase becoming effective, be increased to such
Exercise Price as would have been in effect had the adjustments made upon the
issuance of such Convertible Securities been made upon the basis of (and the
total consideration received therefor) (a) the issuance of the number of shares
of Common Stock theretofore actually delivered upon the exercise of such
Convertible Securities, (b) the issuance of all Common Stock, all Convertible
Securities and all rights and options to purchase Common Stock issued after the
issuance of such Convertible Securities, and (c) the original issuance at the
time of such change of any such Convertible Securities then still outstanding;
PROVIDED, HOWEVER, that any such increase or increases shall not exceed, in the
aggregate, the amount of the original reduction of the Exercise Price
attributable to the Convertible Securities.

                      (C)     If any rights of conversion or exchange evidenced
by such Convertible Securities shall expire without having been exercised, the
adjusted Exercise Price shall forthwith be readjusted to such Exercise Price as
would have been in effect had an adjustment with respect to such Convertible
Securities been made on the basis that the only Additional Shares of Common
Stock issued or sold were those issued upon the conversion or exchange of such
Convertible Securities, and that they were issued or sold for the consideration
actually received by the Company upon such exercise, plus the consideration, if
any, actually received by the Company for the granting of such Convertible
Securities.

               (iii)  (A)     In case at any time on or after the date hereof,
the Company shall in any manner grant or issue any rights or options to
subscribe for, purchase or otherwise acquire Additional Shares of Common Stock,
whether or not such rights or options are immediately exercisable, except for
the granting of employee stock options to purchase one hundred thirty thousand
(130,000) shares of the Company's Common Stock per year, at an exercise price
equal to the Current Market Price, and except for: (x) four hundred
seventy-seven thousand one hundred nineteen (477,119) shares of Common Stock
issuable upon exercise of those outstanding employee stock options which are in
existence as of the date hereof, and (y) one hundred nineteen thousand four
hundred one (119,401) shares of Common Stock issuable upon the exercise of
warrants in existence as of the date hereof, other than this Warrant, and
issuable under certain other agreements of the Company which agreements are in
existence as of the date hereof, as such shares of Common Stock are more fully
set forth in Section 12(a) below, there shall be determined the price per share
for which Additional Shares of Common Stock are issuable upon the 


                                          7
<PAGE>

exercise of such rights or options, such determination to be made by dividing 
(a) the total amount, if any, received or receivable by the Company as 
consideration for the granting of such rights or options, plus the minimum 
aggregate amount of additional consideration, if any, payable to the Company 
upon the exercise of such rights or options if the maximum number of 
Additional Shares were issued pursuant to such rights or options for such 
minimum aggregate amount of additional consideration, by (b) the maximum 
number of Additional Shares of Common Stock of the Company issuable upon the 
exercise of all such rights or options for such minimum aggregate amount of 
additional consideration; and the granting of such rights or options shall be 
deemed to be an issue or sale for cash (as of the date of the granting of 
such rights or options) of such maximum number of Additional Shares of Common 
Stock at the price per share so determined, and shall thereby cause an 
adjustment in the Exercise Price, if such an adjustment is required by 
Section 6(b) hereof.

                      (B)     If such rights or options shall by their terms
provide for an increase or increases, with passage of time, in the amount of
additional consideration payable to the Company upon the exercise thereof, the
adjusted Exercise Price shall, upon any such increases becoming effective, be
increased to such Exercise Price as would have been in effect had the
adjustments made upon the issuance of such rights or options been made upon the
basis of (and the total consideration received therefor) (a) the issuance of the
number of shares of Common Stock theretofore actually delivered upon the
exercise of such rights or options, (b) the issuance of all Common Stock, all
rights and options and all Convertible Securities issued after the issuance of
such rights and options, and (c) the original issuance at the time of such
change of any such rights or options then still outstanding; PROVIDED, HOWEVER,
that any such increase or increases in the Exercise Price shall not exceed, in
the aggregate, the amount of the original reduction of the Exercise Price
attributable to the grant of such rights or options.

                      (C)     If any such rights or options shall expire without
having been exercised, the adjusted Exercise Price shall forthwith be readjusted
to such Exercise Price as would have been in effect had an adjustment with
respect to such rights or options been made on the basis that the only
Additional Shares of Common Stock so issued or sold were those issued or sold
upon the exercise of such rights or options and that they were issued or sold
for the consideration actually received by the Company upon such exercise, plus
the consideration, if any, actually received by the Company for the granting of
such rights or options.

               (iv)   (A)     In case at any time on or after the date hereof,
the Company shall grant any rights or options to subscribe for, purchase or
otherwise acquire Convertible Securities, there shall be determined the price
per share for which Additional Shares of Common Stock are issuable upon the
exchange or conversion of such Convertible Securities if such rights or options
were exercised, such determination to be made by dividing (a) the total amount,
if any, received or receivable by the Company as consideration for the issuance
of such rights or options, plus the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the exercise of such rights
or options if the maximum number of Convertible Securities were issued pursuant
to such


                                          8
<PAGE>

rights or options for such minimum aggregate amount of additional consideration,
plus the minimum aggregate amount of additional consideration, if any, payable
to the Company upon the exchange or conversion of such Convertible Securities if
the maximum number of Additional Shares were issued pursuant to such Convertible
Securities for such minimum aggregate amount of additional consideration, by
(b) the maximum aggregate number of Additional Shares of Common Stock issuable
upon the exchange or conversion of the Convertible Securities for such minimum
aggregate amount of additional consideration; and the issue or sale of such
rights or options shall be deemed to be an issue or sale for cash (as of the
date of the granting of such rights or options) of such maximum number of
Additional Shares of Common Stock at the price per share so determined, and
thereby shall cause an adjustment in the Exercise Price, if such an adjustment
is required by Section 6(b).

                      (B)     If such rights or options to subscribe for or
otherwise acquire Convertible Securities shall by their terms provide for an
increase or increases, with the passage of time, in the amount of additional
consideration payable to the Company upon the exercise, exchange or conversion
thereof, the adjusted Exercise Price shall, forthwith upon any such increase
becoming effective, be increased to such Exercise Price as would have been in
effect had the adjustments made upon the issuances of such rights or options
been made upon the basis of (and the total consideration received therefor)
(a) the issuance of the number of shares of Common Stock theretofore actually
delivered upon the exchange or conversion of such Convertible Securities,
(b) the issuances of all Common Stock and all rights, options and Convertible
Securities issued after the issuance of such rights and options, and (c) the
original issuances at the time of such change of any such rights, options and
Convertible Securities issued upon exercise of such rights or options which are
then still outstanding; provided, however, that any such increase or increases
shall not exceed, in the aggregate, the amount of the original reduction of the
Exercise Price attributable to the grant of such rights or options.

                      (C)     If any such rights, options or rights of
conversion or exchange of such Convertible Securities shall expire without
having been exercised, exchanged or converted, the adjusted Exercise Price shall
forthwith be readjusted to such Exercise Price as would have been in effect had
an adjustment been made with respect to such rights, options or rights of
conversion or exchange of such Convertible Securities on the basis that the only
Additional Shares of Common Stock so issued or sold were those issued or sold
upon the exercise of such rights or options and exchange or conversion of such
Convertible Securities and that they were issued or sold for the consideration
actually received by the Company upon exercise of such rights and options and
exchange or conversion of such Convertible Securities, plus the consideration,
if any, actually received by the Company for the granting of such rights,
options or Convertible Securities.

               (v)    In any case where an adjustment has been made in the
Exercise Price upon the issuance of Convertible Securities or any rights or
options to purchase Convertible Securities or Additional Shares of Common Stock
pursuant to this Section 6(c), no further adjustment shall be made at the time
of the conversion of any such Convertible Securities or at the time of the
exercise of any such rights or options.


                                          9
<PAGE>

               (vi)   In case at any time on or after the issuance of this
Warrant any shares of Common Stock or Convertible Securities shall be issued or
sold for a consideration other than cash, the amount of the consideration other
than cash payable to the Company shall be deemed to be the Fair Value of such
consideration.  Whether or not the consideration so received is cash, the amount
thereof shall be determined after deducting therefrom any expenses incurred or
any underwriting commissions or concessions or discounts paid or allowed by the
Company in connection therewith.

               (vii)  In case at any time the Company shall fix a record date
of the holders of its Common Stock for the purpose of entitling them (a) to
receive a dividend or other distribution payable in Common Stock, Convertible
Securities or rights or options to purchase either thereof, or (b) to subscribe
for or purchase Common Stock, Convertible Securities or rights or options to
purchase either thereof, then such record date shall be deemed to be the date of
the issue or sale of the shares of Common Stock deemed, pursuant to this
Section 6(c), to have been issued or sold upon the declaration of such dividend
or the making of such other distribution or the date of the granting of such
right of subscription or purchase, as the case may be.

               (viii) The number of shares of Common Stock outstanding at any
given time shall not include shares owned or held by or for the account of the
Company, and the disposition of any such shares shall be considered an issue or
sale of Common Stock for the purposes of this Section 6(c).

          (d)  REORGANIZATION, RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE.
If any capital reorganization or reclassification of the capital stock of the
Company, or any consolidation or merger of the Company with another corporation,
or the sale of all or substantially all of its assets to another corporation
shall be effected in such a way that holders of Common Stock shall be entitled
to receive cash, stock, securities or assets with respect to or in exchange for
Common Stock, then, as a condition of such reorganization, reclassification,
consolidation, merger or sale, lawful and adequate provisions shall be made
whereby the Warrantholders shall thereafter have the right to purchase and
receive upon the basis and upon the terms and conditions specified in this
Warrant upon exercise of this Warrant and in lieu of the shares of the Common
Stock of the Company immediately theretofore purchasable and receivable upon the
exercise of the rights represented hereby, such cash, shares of stock,
securities or assets as may be issued or payable with respect to or in exchange
for a number of outstanding shares of Common Stock equal to the number of shares
of such Common Stock immediately theretofore purchasable and receivable upon the
exercise of the rights represented hereby, and in any such case appropriate
provision shall be made with respect to the rights and interest of the
Warrantholders to the end that the provisions hereof (including, without
limitation, provisions for adjustments of the Exercise Price and of the number
of shares purchasable and receivable upon the exercise of this Warrant) shall
thereafter be applicable, as nearly as may be, in relation to any shares of
stock, securities or assets thereafter deliverable upon the exercise hereof.
The Company shall not effect any consolidation, merger or sale of all or
substantially all of the assets of the Company unless prior to or simultaneous
with the consummation thereof the successor


                                          10
<PAGE>

corporation (if other than the Company) resulting from such consolidation,
merger or purchase of such assets shall assume, by written instrument executed
and mailed or delivered to the Warrantholders, the obligation to deliver to such
Warrantholders such cash (or cash equivalent), shares of stock, securities or
assets as, in accordance with the foregoing provisions, the Warrantholders may
be entitled to receive and containing the express assumption of such successor
corporation of the due and punctual performance and observance of each provision
of this Warrant to be performed and observed by the Company and of all
liabilities and obligations of the Company hereunder; PROVIDED, HOWEVER, in the
case of any consolidation or merger of the Company with another corporation or
the sale of all or substantially all of its assets to another corporation
effected in such a manner that the holders of Common Stock shall be entitled to
receive stock, securities or assets with respect to or in exchange for Common
Stock, then, at the election of each Warrantholder, in lieu of receiving such
stock, securities or assets, such Warrantholder shall receive cash equal to the
Fair Value of the Common Stock issuable upon exercise of the Warrant, less the
Exercise Price payable upon exercise thereof.

               In case any Additional Shares of Common Stock or Convertible
Securities or any rights or options to purchase any Additional Shares of Common
Stock or Convertible Securities shall be issued in connection with any merger of
another corporation into the Company, except for any acquisitions made by the
Company with the proceeds of the loan from the Bank, as set forth in the Loan
Agreement, of management service organizations which manage medical practices,
the amount of consideration therefor shall be deemed to be the Fair Value of
such portion of the assets of such merged corporation as the Board of Directors
of the Company shall in good faith determine to be attributable to such
Additional Shares of Common Stock, Convertible Securities or rights or options,
as the case may be, and the Exercise Price shall be adjusted in accordance with
this Section 6(d).

          (e)  COMPANY TO PREVENT DILUTION.  In case at any time or from time to
time conditions arise by reason of action taken by the Company which are not
adequately covered by the provisions of this Section 6, and which might
materially and adversely affect the exercise rights of the Warrantholders under
any provision of this Warrant, unless the adjustment necessary shall be agreed
upon by the Company and the Warrantholders, the Board of Directors of the
Company shall appoint a firm of independent certified public accountants of
recognized national standing (who have not been employed by the Company within
the last five years), acceptable to the Warrantholders, who at the Company's
expense shall give their opinion upon the adjustment, if any, on a basis
consistent with the standards established in the other provisions of this
Section 6, necessary with respect to the Exercise Price and the number of shares
purchasable upon exercise of the Warrants, so as to preserve, without dilution,
the exercise rights of the Warrantholders.  Upon receipt of such opinion, such
Board of Directors shall forthwith make the adjustments described therein.

          (f)  STOCK SPLITS AND REVERSE SPLITS.  In case at any time the Company
shall subdivide its outstanding shares of Common Stock into a greater number of
shares, the Exercise Price in effect immediately prior to such subdivision shall
be proportionately


                                          11
<PAGE>

reduced and the number of shares of Common Stock purchasable pursuant to this
Warrant immediately prior to such subdivision shall be proportionately
increased, and conversely, in case at any time the Company shall combine its
outstanding shares of Common Stock into a smaller number of shares, the Exercise
Price in effect immediately prior to such combination shall be proportionately
increased and the number of shares of Common Stock purchasable upon the exercise
of this Warrant immediately prior to such combination shall be proportionately
reduced.

          (g)  DISSOLUTION, LIQUIDATION AND WINDING-UP.  In case the Company
shall, at any time prior to the expiration of this Warrant, dissolve, liquidate
or wind up its affairs, the Warrantholders shall be entitled, upon the exercise
of this Warrant, to receive, in lieu of the shares of Common Stock of the
Company which such Warrantholders would have been entitled to receive, the same
kind and amount of assets as would have been issued, distributed or paid to such
Warrantholders upon any such dissolution, liquidation or winding up with respect
to such shares of Common Stock of the Company, had such Warrantholders been the
holders of record of the Warrant Shares receivable upon the exercise of this
Warrant on the record date for the determination of those persons entitled to
receive any such liquidating distribution.  After any such dissolution,
liquidation or winding up which shall result in any cash distribution in excess
of the Exercise Price provided for by this Warrant, the Warrantholders may, at
each such Warrantholder's option, exercise the same without making payment of
the Exercise Price, and in such case the Company shall, upon the distribution to
said Warrantholders, consider that said Exercise Price has been paid in full to
it and in making settlement to said Warrantholders, shall deduct from the amount
payable to such Warrantholders an amount equal to such Exercise Price.

          (h)  NONCASH CONSIDERATION.  In case any Additional Shares of Common
Stock or Convertible Securities or any rights or options to purchase any
Additional Shares of Common Stock or Convertible Securities shall be issued for
a consideration in a form other than cash, the amount of such consideration
shall be deemed to be the Fair Value thereof.

          (i)  ACCOUNTANTS' CERTIFICATE.  In each case of an adjustment in the
number of shares of Common Stock or other stock, securities or property
receivable on the exercise of the Warrants, the Company at its expense shall
cause independent public accountants of recognized standing selected by the
Company and acceptable to the Warrantholders to compute such adjustment in
accordance with the terms of this Warrant and prepare a certificate setting
forth such adjustment and showing in detail the facts upon which such adjustment
is based, including a statement of (a) the consideration received or to be
received by the Company for any Additional Shares of Common Stock, rights,
options or Convertible Securities issued or sold or deemed to have been issued
or sold, (b) the number of shares of Common Stock of each class outstanding or
deemed to be outstanding, (c) the adjusted Exercise Price and (d) the number of
shares issuable upon exercise of this Warrant.  The Company will forthwith mail
a copy of each such certificate to each Warrantholder.


                                          12

     7.   SPECIAL AGREEMENTS OF THE COMPANY.

          (a)  RESERVATION OF SHARES.  The Company covenants and agrees that all
Warrant Shares will, upon issuance, be validly issued, fully paid and
nonassessable and free from all preemptive rights of any stockholder, and from
all taxes, liens and charges with respect to the issue thereof.  The Company
further covenants and agrees that during the period within which the rights
represented by this Warrant may be exercised, the Company will at all times have
authorized, and reserved, a sufficient number of shares of Common Stock to
provide for the exercise of the rights represented by this Warrant.  The Company
hereby covenants and agrees to take all such action as may be necessary to
assure that the par value per share of the Common Stock is at all times equal to
or less than the Exercise Price.

          (b)  AVOIDANCE OF CERTAIN ACTIONS.  The Company will not, by amendment
of its Articles or Certificate of Incorporation or through any reorganization,
transfer of assets, consolidation, merger, issue or sale of securities or
otherwise, avoid or take any action which would have the effect of avoiding the
observance or performance of any of the terms to be observed or performed
hereunder by the Company, but will at all times in good faith assist in carrying
out all of the provisions of this Warrant and in taking all of such action as
may be necessary or appropriate in order to protect the rights of the
Warrantholders against dilution or other impairment of their rights hereunder.

          (c)  SECURING GOVERNMENTAL APPROVALS.  If any shares of Common Stock
required to be reserved for the purposes of exercise of this Warrant require
registration with or approval of any governmental authority under any federal
law (other than the Securities Act) or under any state law before such shares
may be issued upon exercise of this Warrant, the Company will, at its expense,
as expeditiously as possible, cause such shares to be duly registered or
approved, as the case may be.

          (d)  LISTING ON SECURITIES EXCHANGES; REGISTRATION.  If, and so long
as, any class of the Company's Common Stock shall be listed on any national
securities exchange (as defined in the Exchange Act), the Company will, at its
expense, obtain and maintain the approval for listing upon official notice of
issuance of all Warrant Shares and maintain the listing of Warrant Shares after
their issuance; and the Company will so list on such national securities
exchange, will register under the Exchange Act (or any similar statute then in
effect), and will maintain such listing of, any other securities that at any
time are issuable upon exercise of this Warrant if and at the time any
securities of the same class shall be listed on such national securities
exchange by the Company.

          (e)  INFORMATION RIGHTS.  So long as the Warrantholders hold this
Warrant and/or any of the Warrant Shares, the Company shall deliver to the
Warrantholders (i) promptly after mailing, copies of all communications to the
shareholders of the Company, (ii) within ninety (90) days after the end of each
fiscal year of the Company, the annual audited financial statements of the
Company certified by the independent public accountants of recognized standing,
and (iii) within forty-five (45) days after the end of each


                                          13
<PAGE>

of the first three quarters of each fiscal year, the Company's quarterly,
unaudited financial statements.

          (f)  RESTRICTIONS ON PUBLIC SALE BY THE COMPANY.  The Company will not
effect any public or private sale or distribution of its convertible debt or
equity securities, including a sale pursuant to Regulation D under the
Securities Act, during the Protected Period of each underwritten offering by the
Company made pursuant to a registration statement filed pursuant to
Sections 11(a) or 11(b).  In addition, the Company shall cause each holder of
its privately placed convertible debt or equity securities issued by it at any
time on or after the date of this Warrant to agree not to effect any public sale
or distribution of any such securities during such Period, including a sale
pursuant to Rule 144 or Rule 144A under the Securities Act; provided, however,
that no such agreement shall be required with respect to any such debt or equity
securities which are to be issued by the Company in a transaction which is
intended to be treated as a pooling of interests if the existence of such
agreement would cause the transaction to fail to qualify for such treatment.

          (g)  PREEMPTIVE RIGHTS.  In the event the Company offers to the
Company's shareholders the right to purchase any securities of the Company, then
all shares of Common Stock issuable pursuant to the Warrants shall be deemed to
be issued and outstanding and held by the Warrantholders and the Warrantholders
shall be entitled to participate in such rights offering.

          (h)  COMPLIANCE WITH LAW.  The Company shall comply with all
applicable laws, rules and regulations of the United States and of all states,
municipalities and agencies and of any other jurisdiction applicable to the
Company and shall do all things necessary to preserve, renew and keep in full
force and effect and in good standing its corporate existence and authority
necessary to continue its business.

     8.   FRACTIONAL SHARES.  No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant.  With
respect to any fraction of a share called for upon exercise hereof, the Company
shall pay to the Warrantholder an amount in cash equal to such fraction
multiplied by the Current Market Value of one share of Common Stock.

     9.   NOTICES OF STOCK DIVIDENDS, SUBSCRIPTIONS, RECLASSIFICATIONS,
CONSOLIDATIONS, MERGERS, ETC.  If at any time:  (i) the Company shall declare a
cash dividend (or an increase in the then existing dividend rate), or declare a
dividend on Common Stock payable otherwise than in cash out of its net earnings
after taxes for the prior fiscal year; or (ii) the Company shall authorize the
granting to the holders of Common Stock of rights to subscribe for or purchase
any shares of capital stock of any class or of any other rights; or (iii) there
shall be any capital reorganization, or reclassification, or redemption of the
capital stock of the Company, or consolidation or merger of the Company with, or
sale of all or substantially all of its assets to, another corporation or firm;
or (iv) there shall be a voluntary or involuntary dissolution, liquidation or
winding up of the Company, then the Company shall give to the Warrantholders at
the addresses of such Warrantholders as shown


                                          14
<PAGE>

on the books of the Company, at least twenty (20) days prior to the applicable
record date hereinafter specified, a written notice summarizing such action or
event and stating the record date for any such dividend or rights (or, if a
record date is not to be selected, the date as of which the holders of Common
Stock of record entitled to such dividend or rights are to be determined), the
date on which any such reorganization, reclassification, consolidation, merger,
sale of assets, dissolution, liquidation or winding up is expected to become
effective, and the date as of which it is expected the holders of Common Stock
of record shall be entitled to effect any exchange of their shares of Common
Stock for cash (or cash equivalent), securities or other property deliverable
upon any such reorganization, reclassification, consolidation, merger, sale of
assets, dissolution, liquidation or winding up.

     10.  REGISTERED HOLDER; TRANSFER OF WARRANTS OR WARRANT SHARES.

          (a)  MAINTENANCE OF REGISTRATION BOOKS; OWNERSHIP OF THIS WARRANT.
The Company shall keep at its principal office a register in which the Company
shall provide for the registration, transfer and exchange of this Warrant.  The
Company shall not at any time, except upon the dissolution, liquidation or
winding-up of the Company, close such register so as to result in preventing or
delaying the exercise or transfer of this Warrant.

          (b)  EXCHANGE AND REPLACEMENT.  This Warrant is exchangeable upon
surrender hereof by the registered holder to the Company at its principal office
for new Warrants of like tenor and date representing in the aggregate the right
to purchase the number of shares purchasable hereunder, each of such new
Warrants to represent the right to purchase such number of shares as shall be
designated by said registered holder at the time of surrender.  Subject to
compliance with all restrictions and provisions of this Warrant, this Warrant
and all rights hereunder are transferable in whole or in part upon the books of
the Company by the registered holder hereof in person or by duly authorized
attorney, and new Warrants shall be made and delivered by the Company, of the
same tenor and date as this Warrant but registered in the name of the
transferee(s), upon surrender of this Warrant, duly endorsed, to said office of
the Company.  Upon receipt by the Company of evidence reasonably satisfactory to
it of the loss, theft, destruction or mutilation of this Warrant, and upon
surrender and cancellation of this Warrant, if mutilated, the Company will make
and deliver a new Warrant of like tenor, in lieu of this Warrant, without
requiring the posting of any bond or the giving of any other security.  This
Warrant shall be promptly cancelled by the Company upon the surrender hereof in
connection with any exchange, transfer or replacement.  The Company shall pay
all expenses, taxes and other charges payable in connection with the
preparation, execution and delivery of Warrants pursuant to this Section 10.

          (c)  WARRANTS AND WARRANT SHARES NOT REGISTERED.  The holder of this
Warrant, by accepting this Warrant, represents and acknowledges that this
Warrant and the Warrant Shares are not being registered under the Securities Act
on the grounds that the issuance of this Warrant and the offering and sale of
such Warrant Shares are exempt from registration under Section 4(2) of the
Securities Act as not involving any public offering.


                                          15
<PAGE>

     11.  REGISTRATION.

          (a)  REQUIRED REGISTRATION.  After three (3) years from the date of
this Warrant, whenever the Company shall receive a written request therefor from
any holder or holders of at least 10% of the Registrable Stock, the Company
shall promptly prepare and file a registration statement under the Securities
Act covering the Registrable Stock which is the subject of such request and
shall use its best efforts to cause such registration statement to become
effective as expeditiously as possible.  Upon the receipt of such request, the
Company shall promptly give written notice to all holders of Registrable Stock
that such registration is to be effected.  The Company shall include in such
registration statement such Registrable Stock for which it has received written
requests to register such shares by the holders thereof within thirty (30) days
after the effectiveness of the Company's written notice to such other holders.
The Registrable Stock owned by the Bank under this Warrant shall receive
priority over all other shares of stock included in a registration statement
under this Section 11(a).  Notwithstanding the above, the Company is obligated
to effect only one (1) registration pursuant to this Section 11(a).

          (b)  INCIDENTAL REGISTRATION.  Each time the Company shall determine
to file a registration statement under the Securities Act (other than on
Form S-8 or Form S-4) in connection with the proposed offer and sale for money
of any of its securities by it or by any of its security holders, the Company
will give written notice of its determination to all holders of Registrable
Stock.  Upon the written request of a holder of any Registrable Stock, the
Company will cause all such Registrable Stock, the holders of which have so
requested registration thereof, to be included in such registration statement,
all to the extent requisite to permit the sale or other disposition by the
prospective seller or sellers of the Registrable Stock to be so registered in
accordance with the terms of the proposed offering.  If the registration
statement is to cover an underwritten distribution, the Company shall use its
best efforts to cause the Registrable Stock requested for inclusion pursuant to
this Section 11(b) to be included in the underwriting on the same terms and
conditions as the securities otherwise being sold through the underwriters.  If,
in the good faith judgment of the managing underwriter of such public offering,
the inclusion of all of the Registrable Stock requested to be registered would
materially and adversely affect the successful marketing of the other shares
proposed to be offered, then the amount of the Registrable Stock to be included
in the offering shall be reduced and the Registrable Stock and the other shares
to be offered shall participate in such offering as follows:  the shares to be
sold by the Company, the Registrable Stock to be included in such offering and
the other shares of Common Stock to be included in such offering shall each be
reduced pro rata in proportion to the number of shares of Common Stock proposed
to be included in such offering by each holder of such shares and by the
Company.

          (c)  REGISTRATION PROCEDURES.  If and whenever the Company is required
by the provisions of Section 11(a) or 11(b) to effect the registration of
Registrable Stock under the Securities Act, the Company will, at its expense, as
expeditiously as possible:

required to be stated therein or necessary to make the statements therein not
misleading;

               (ix)   In case any of such holders or any underwriter for any

then in circulation is not in compliance with the Securities Act or the rules
and regulations of the Commission, prepare promptly upon request such amendments
or supplements to such registration statement and such prospectus as may be
necessary in order for such prospectus to comply with the requirements of the
Securities Act and such rules and regulations;

               (x)    Advise such holders, promptly after it shall receive
notice or obtain knowledge thereof, of the issuance of any stop order by the
Commission suspending the effectiveness of such registration statement or the
initiation or threatening of any proceeding for that purpose and promptly use
its best efforts to prevent the issuance of any stop order or to obtain its
withdrawal if such stop order should be issued;

               (xi)   If requested by the managing underwriter or underwriters

relating to the plan of distribution with respect to such Registrable Stock,
including information with respect to the Registrable Stock being sold to such
underwriters, the purchase price being paid therefor by such underwriters and
with respect to any other terms of the underwritten (or best efforts
underwritten) offering of the Registrable Stock to be sold in such offering; and

amendment as soon as notified of the matters to be incorporated in such
prospectus supplement or post-effective amendment;

               (xii)  Cooperate with the selling holders of Registrable Stock
and the managing underwriters, if any, to facilitate the timely preparation and
delivery of certificates representing Registrable Stock to be sold and not
bearing any restrictive legends; and enable such Registrable Stock to be in such
denominations and registered in such names as the managing underwriters may
request at least two business days prior to any sale of Registrable Stock to the
underwriters;

               (xiii) Prepare a prospectus supplement or post-effective
amendment to the registration statement or the related prospectus or any

state any material fact necessary to make the statements therein not misleading;


                                          18
<PAGE>

               (xiv)  Enter into such agreements (including an underwriting
agreement) and take all such other actions in connection therewith in order to
expedite or facilitate the disposition of such Registrable Stock and in such
connection, whether or not an underwriting agreement is entered into and whether
or not the registration is an underwritten registration:

                      (A)     make such representations and warranties to the
holders of such Registrable Stock and the underwriters, if any, in form,
substance and scope as are customarily made by issuers to underwriters in
primary underwritten offerings;

                      (B)     If an underwriting agreement is entered into, the
same shall set forth in full the indemnification provisions and procedures of
Section 11(e) hereof with respect to all parties to be indemnified pursuant to

                      (C)     The Company shall deliver such documents and
certificates as may be requested by the holders of the majority of the

               (xv)   Make available for inspection by a representative of the
holders of a majority of the Registrable Stock, any underwriter participating in
any disposition pursuant to a registration statement, and any attorney or
accountant retained by the sellers or underwriter, all financial and other
records, pertinent corporate documents and properties of the Company, and cause
the Company's officers, directors and employees to supply all information
reasonably requested by any such representative, underwriter, attorney or
accountant in connection with the preparation of the registration statement;
provided, that any records, information or documents that are designated by the

unless disclosure of such records, information or documents is required by court

               (xvi)  Otherwise use its best efforts to comply with all

the end of any twelve (12) month period (or ninety (90) days, if such a period
is a fiscal year) (i) commencing at the end of any fiscal quarter in which
Registrable Stock is sold to underwriters in an underwritten offering, or, if
not sold to underwriters in such an offering, (ii) beginning with the first

                                          19
<PAGE>

               (xvii) Not file any amendment or supplement to such registration
statement or prospectus to which a majority in interest of such holders has
objected on the grounds that such amendment or supplement does not comply in all
material respects with the requirements of the Securities Act or the rules and
regulations thereunder, after having been furnished with a copy thereof at least
five (5) business days prior to the filing thereof; provided, however, that the
failure of such holders or their counsel to review or object to any amendment or
supplement to such registration statement or prospectus shall not affect the
rights of such holders or any controlling person or persons thereof or any
underwriter or underwriters therefor under Section 11(e) hereof; and

               (xviii)   At the request of any such holder (i) furnish to such
holder on the effective date of the registration statement or, if such
registration includes an underwritten public offering, at the closing provided
for in the underwriting agreement, an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, addressed to the
underwriters, if any, and to the holder or holders making such request, covering
such matters with respect to the registration statement, the prospectus and each
amendment or supplement thereto, proceedings under state and federal securities
laws, other matters relating to the Company, the securities being registered and
the offer and sale of such securities as are customarily the subject of opinions
of issuer's counsel provided to underwriters in underwritten public offerings,
and such opinion of counsel shall additionally cover such legal and factual
matters with respect to the registration as such requesting holder or holders
may reasonably request, and (ii) use its best efforts to furnish to such holder
letters dated each such effective date and such closing date, from the
independent certified public accountants of the Company, addressed to the
underwriters, if any, and to the holder or holders making such request, stating

Securities Act and dealing with such matters as the underwriters may request,
or, if the offering is not underwritten, that in the opinion of such accountants
the financial statements and other financial data of the Company included in the
registration statement or the prospectus or any amendment or supplement thereto
comply in all material respects with the applicable accounting requirements of
the Securities Act, and additionally covering such other financial matters,
including information as to the period ending immediately prior to the date of
such letter with respect to the registration statement and prospectus, as such
requesting holder or holders may reasonably request.

          (d)  EXPENSES OF REGISTRATION.  All expenses incident to the Company's
performance of or compliance with this Warrant, including, without limitation,
the following shall be borne by the Company, regardless of whether the

respect to filings required to be made with the National Association of
Securities Dealers, Inc.);

               (iii)  Printing, messenger, telephone and delivery expenses;

               (iv)   Fees and disbursements of counsel for the Company, the

               (vii)  Fees and expenses of other persons retained by the

holders of a majority of such Registrable Stock.

          (e)  INDEMNIFICATION.

               (i)    The Company hereby agrees to indemnify each of the
holders of Registrable Stock against all claims, losses, damages and liabilities
(or actions in respect thereof) arising out of or based on any untrue statement
(or alleged untrue statement) of a material fact contained in any registration
statement, preliminary or final prospectus, or other document incident to any
such registration, qualification or compliance (or in any related registration
statement, notification or the like) or any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, or any violation by the Company of any
rule or regulation promulgated under the Securities Act applicable to the
Company and relating to action or


                                          21
<PAGE>

inaction required of the Company in connection with any such registration,
qualification or compliance, and to reimburse the holders of Registrable Stock
(including officers and directors of the same and controlling persons) for any
legal and any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability or action,
PROVIDED, HOWEVER, that the Company will not be liable in any such case to the
extent that any such claim, loss, damage or liability arises out of or is based
on any untrue statement or omission based upon written information furnished to
the Company by Warrantholders in an instrument duly executed by Warrantholders
and stated to be specifically for use therein.

               (ii)   The Warrantholders severally and not jointly agree to
indemnify the Company and its officers and directors and each person, if any,
who controls any thereof within the meaning of Section 15 of the Securities Act
and their respective successors against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement of a material fact contained in any prospectus, offering
circular or other document incident to any registration, qualification or
compliance relating to securities purchased pursuant to the Warrants (or in any
related registration statement, notification or the like) or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading and will reimburse
the Company and each other person indemnified pursuant to this subsection (ii)
for any legal and any other expenses reasonably incurred in connection with
investigating or defending any such claim, loss, damage, liability or action;
PROVIDED, HOWEVER, that this subsection (ii) shall apply only if (and only to
the extent that) such statement or omission was made in reliance upon
information (including, without limitation, written negative responses to
inquiries) furnished to the Company by an instrument duly executed by
Warrantholders and stated to be specifically for use in such prospectus, or
other document (or related registration statement, notification or the like) or
any amendment or supplement thereto.

               (iii)  Each party entitled to indemnification hereunder (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party (at such Indemnifying Party's expense) to assume
the defense of any claim or any litigation resulting therefrom, provided that
counsel for the Indemnifying Party, who shall conduct the defense of such claim
or litigation, shall be satisfactory to the Indemnified Party, and the
Indemnified Party may participate in such defense at such party's expense, and
provided, further, that the omission by any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations
under this Section 11(e) except to the extent that the omission results in a
failure of actual notice to the Indemnifying Party and such Indemnifying Party
is materially damaged solely as a result of the failure to give notice.  No
Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the


                                          22
<PAGE>

claimant or plaintiff to such Indemnified Party of a release from all liability
in respect to such claim or litigation.

               (iv)   If the indemnification provided for in this Section 11(e)
is unavailable or insufficient to hold harmless an Indemnified Party in respect
of any losses, claims, damages, liabilities, expenses or actions in respect
thereof referred to herein, then the Indemnifying Party shall contribute to the
amount paid or payable by such Indemnified Party as a result of such losses,
claims, damages, liabilities, expenses or actions in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party on the one
hand, and the Indemnified Party on the other, in connection with the statements
or omissions which resulted in such losses, claims, damages, liabilities,
expenses or actions as well as any other relevant equitable considerations,
including the failure to give the notice required hereunder.  The relative fault
of the Indemnifying Party and the Indemnified Party shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact relates to information supplied by the Indemnifying Party or
the Indemnified Party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Warrantholders  agree that it would not be just and
equitable if contributions pursuant to this Section 11(e) were determined by pro
rata allocation or by any other method of allocation which did not take account
of the equitable considerations referred to above.  The amount paid or payable
to an Indemnified Party as a result of the losses, claims, damages, liabilities
or actions in respect thereof, referred to above, shall be deemed to include any
legal or other expenses reasonably incurred by such Indemnified Party in
connection with investigating or defending any such action or claim.
Notwithstanding the contribution provisions of this Section 11(e), in no event
shall the amount contributed by any seller of Registrable Stock exceed the
aggregate net offering proceeds received by such seller from the sale of
Registrable Stock to which such contribution or indemnification claim relates.
No person guilty of fraudulent misrepresentations (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who is not guilty of such fraudulent misrepresentation.

               (v)    The indemnification required by this Section 11(e) shall
be made by periodic payments during the course of the investigation or defense,
as and when bills are received or expenses incurred.  Anything contained herein
to the contrary notwithstanding, the maximum aggregate liability of any holder
of Registrable Stock under this Section 11(e) shall not exceed the amount of the
net proceeds actually received by such holder from the sale of its Registrable
Stock pursuant to the registration, qualification, notification or compliance in
respect of which such liability arose.

          (f)  REPORTING REQUIREMENTS UNDER EXCHANGE ACT.  From and after the
effective date of the first registration statement filed by the Company under
the Securities Act, the Company shall (whether or not it shall then be required
to do so) timely file such information, documents and reports as the Commission
may require or prescribe under Section 13 or 15(d) (whichever is applicable) of
the Exchange Act.  Immediately upon becoming subject to the reporting
requirements of either Section 13 or 15(d) of the


                                          23
<PAGE>

Exchange Act, the Company shall forthwith upon request furnish any holder of
Registrable Stock (i) a written statement by the Company that it has complied
with such reporting requirements, (ii) a copy of the most recent annual or
quarterly report of the Company, and (iii) such other reports and documents
filed by the Company with the Commission as such holder may reasonably request
in availing itself of an exemption for the sale of Registrable Stock without
registration under the Securities Act.  The Company acknowledges and agrees that
the purpose of the requirements contained in this Section 11(f) is to enable any
such holder to comply with the current public information requirement contained
in Rule 144 under the Securities Act should such holder ever wish to dispose of
any of the securities of the Company acquired by it without registration under
the Securities Act in reliance upon Rule 144 (or any other similar exemptive
provision).  In addition, the Company shall take such other measures and file
such other information, documents and reports as shall hereafter be required by
the Commission as a condition to the availability of Rule 144 and Rule 144A
under the Securities Act (or any similar exemptive provision hereafter in
effect).

          (g)  STOCKHOLDER INFORMATION.  The Company may require each holder of
Registrable Stock as to which any registration is to be effected pursuant to
this Section 11 to furnish the Company such information with respect to such
holder and the distribution of such Registrable Stock as shall be required by
law or by the Commission in connection therewith.

     12.  REPRESENTATION AND WARRANTIES.  The Company hereby represents and
warrants to and covenants with Imperial, the Bank, each Warrantholder, and each
holder of Warrant Shares that:

          (a)  ORGANIZATION AND CAPITALIZATION OF THE COMPANY.  The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware.  As of the date hereof, the authorized capital of the
Company consists of forty million (40,000,000) shares of Common Stock and one
million (1,000,000) shares of Preferred Stock, of which four million six hundred
ninety-eight thousand four hundred seventy-one (4,698,471) shares of Common
Stock and no shares of Preferred Stock are issued and outstanding.  The Company
has, and at all times during the Exercise Period will have, reserved for
issuance pursuant to the Warrants that number of shares of Common Stock that are
issuable pursuant to the Warrants.  No unissued shares of Common Stock are
reserved for any purpose other than: (i) for issuance upon the exercise of the
Warrants, (ii) four hundred seventy-seven thousand one hundred nineteen
(477,119) shares of Common Stock reserved for issuance upon the exercise of
employee stock options, and (iii) one hundred nineteen thousand four hundred one
(119,401) shares of Common Stock reserved for issuance upon the exercise of
warrants other than this Warrant and under certain other agreements of the
Company as in existence on the date hereof.  There are no preemptive rights in
effect with respect to the issuance of any shares of Common Stock.  All the
outstanding shares of Common Stock and Preferred Stock have been validly issued
without violation of any preemptive or similar rights, are fully paid and
nonassessable and have been issued in compliance with all federal and applicable
state securities laws.


                                          24
<PAGE>

          (b)  AUTHORITY.  The Company has full corporate power and authority to
execute and deliver this Warrant, to issue the shares of Common Stock issuable
upon exercise of this Warrant, and to perform all of its obligations hereunder,
and the execution, delivery and performance hereof has been duly authorized by
all necessary corporate action on its part.  This Warrant has been duly executed
on behalf of the Company and constitutes the legal, valid and binding obligation
of the Company enforceable in accordance with its terms.

          (c)  NO LEGAL BAR.  Neither the execution, delivery or performance of
this Warrant nor the issuance of the shares of Common Stock issuable upon
exercise of this Warrant will (a) conflict with or result in a violation of the
Certificate of Incorporation or By-Laws of the Company, (b) conflict with or
result in a violation of any law, statute, regulation, order or decree
applicable to the Company or any affiliate, (c) require any consent or
authorization or filing with, or other act by or in respect of any governmental
authority, or (d) result in a breach of, constitute a default under or
constitute an event creating rights of acceleration, termination or cancellation
under any mortgage, lease, contract, franchise, instrument or other agreement to
which the Company is a party or by which it is bound.

          (d)  VALIDITY OF SHARES.  When issued upon the exercise of this
Warrant as contemplated herein, the shares of Common Stock so issued will have
been validly issued and will be fully paid and nonassessable.  On the date
hereof, the par value of the Common Stock is less than the Exercise Price per
share of Common Stock.

     13.  CONTINUING VALIDITY.  The Bank and each holder of Warrant Shares shall
continue to be entitled to all rights to which a Warrantholder is entitled
pursuant to the provisions of this Warrant except such rights as by their terms
apply solely to a Warrantholder, notwithstanding the fact that this Warrant has
been exercised or the period of exercisability has expired.  The Company will,
at any time upon the request of the Bank or a holder of the Warrant Shares,
acknowledge in writing, in form reasonably satisfactory to the Bank or such
holder, the Company's continuing obligation to afford to the Bank or such holder
all rights to which the Bank or such holder shall continue to be entitled in
accordance with the provisions of this Warrant; PROVIDED, HOWEVER, that if the
Bank or such holder shall fail to make any such request, such failure shall not
affect the continuing obligation of the Company to afford to Imperial, the Bank
and such holder all such rights.

     14.  MISCELLANEOUS PROVISIONS.

          (a)  NOTICE OF EXPIRATION.  The Company shall give written notice to
the Warrantholders specifically advising them of the Expiration Date and of
their right to exercise the Warrants not more than one hundred eighty (180) days
and not less than ninety (90) days before the Expiration Date.  If such written
notice is not so given, the Expiration Date shall automatically be extended
until ninety (90) days after the date that the Company gives the Warrantholders
such written notice.

          (b)  JUDICIAL REFERENCE.

               (i)    Other than the appointment of a receiver, or the exercise
of other provisional remedies (any and all of which may be initiated pursuant to
applicable law), each controversy, dispute or claim arising out of or relating
to this Warrant, which controversy, dispute or claim is not settled in writing
within thirty (30) days after the "CLAIM DATE" (defined as the date on which the
Company or a Warrantholder gives written notice to the other that a controversy,
dispute or claim exists), will be settled by a reference proceeding in
California in accordance with the provisions of Section 638 et seq. of the
California Code of Civil Procedure, or their successor section ("CCP"), which
shall constitute the exclusive remedy for the settlement of any controversy,
dispute or claim concerning this Warrant, including whether such controversy,
dispute or claim is subject to the reference proceeding and except as set forth
above, the parties waive their rights to initiate any legal proceedings against
each other in any court or jurisdiction other than the Superior Court in
counties of Los Angeles or Orange, California (the "COURT").  The referee shall
be a retired Judge of the Court selected by mutual agreement of the parties, and
if they cannot so agree within forty-five (45) days after the Claim Date, the
referee shall be promptly selected by the Presiding Judge of the Court (or his
or her representative).  The referee shall be appointed to sit as a temporary
judge, with all of the powers for a temporary judge, as authorized by law, and
upon selection should take and subscribe to the oath of office as provided for
in Rule 244 of the California Rules of Court (or any subsequently enacted Rule).
Each party shall have one peremptory challenge pursuant to CCP Section 170.6.
The referee shall (i) be requested to set the matter for hearing within sixty
(60) days after the Claim Date and (ii) try any and all issues of law or fact
and report a statement of decision upon them, if possible, within ninety (90)
days of the Claim Date.  Any decision rendered by the referee will be final,
binding and conclusive and judgment shall be entered pursuant to CCP Section 644
in any court in the State of California having jurisdiction.  Any party may
apply for a reference proceeding at any time after thirty (30) days following
notice to any other party of the nature of the controversy, dispute or claim, by
filing a petition for a hearing and/or trial.  All discovery permitted by this
Warrant shall be completed no later than fifteen (15) days before the first
hearing date established by the referee.  The referee may extend such period in
the event of a party's refusal to provide requested discovery for any reason
whatsoever, including, without limitation, legal objections raised to such
discovery or unavailability of a witness due to absence or illness.  No party
shall be entitled to "priority" in conducting discovery.  Depositions may be
taken by either party upon seven (7) days written notice, and request for
production or inspection of documents shall be responded to within ten (10) days
after service.  All disputes relating to discovery which cannot be resolved by
the parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Court is empowered to issue temporary and/or provisional remedies,
as appropriate.

               (ii)   Except as expressly set forth in this Warrant, the
referee shall determine the manner in which the reference proceeding is
conducted including the time and place of all hearings, the order of
presentation of evidence, and all other questions that arise


                                          26
<PAGE>

with respect to the course of the reference proceeding.  All proceedings and
hearings conducted before the referee, except for trial, shall be conducted
without a court reporter except that when any party so requests, a court
reporter will be used at any hearing conducted before the referee.  The party
making such a request shall have the obligation to arrange for and pay for the
court reporter.  The costs of the court reporter at the trial shall be borne
equally by the parties.

               (iii)  The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties.  The referee shall issue a single judgment at the
close of the reference proceeding which shall dispose of all of the claims of
the parties that are the subject of the reference.  The parties hereto expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee.  The parties hereto
expressly reserve the right to findings of fact, conclusions of laws, a written
statement of decision, and the right to move for a new trial or a different
judgment, which new trial, if granted, is also to be a reference proceeding
under this provision.

               (iv)   In the event that the enabling legislation which provides
for appointment of a referee is repealed (and no successor statute is enacted),
any dispute between the parties that would otherwise be determined by the
reference procedure herein described will be resolved and determined by
arbitration.  The arbitration will be conducted by a retired judge of the Court,
in accordance with the California Arbitration Act, Section 1280 through Section
1294.2 of the CCP as amended from time to time.  The limitations with respect to
discovery as set forth hereinabove shall apply to any such arbitration
proceeding.

                   AMENDED AND RESTATED ASSIGNABLE OPTION AGREEMENT

     THIS AMENDED AND RESTATED ASSIGNABLE OPTION AGREEMENT ("Agreement") is made
as of the 2nd day of September, 1998, and deemed to have been effective as of
July 14, 1997, by and among Prospect Medical Systems, Inc. ("Prospect Medical

California professional medical corporation ("Group"), together with Prospect
Medical Group, Inc., a California professional corporation ("Prospect Medical

                                       RECITALS

     A.   Group is a professional corporation that is organized and operated as
an independent practice association (the "Practice").

     B.   Group, Prospect Medical Group and Melvin L. Reich, D.O. ("Reich")

Medical Group, (i) an assignable option to purchase all of the assets of Group,
and (ii) the right to designate the purchaser ("Successor Physician") of all or
part of the issued and outstanding stock in Group.  When used in this Agreement,
the term "Assets" shall mean all of Group's and Prospect Medical Group's right,
title, interest and estate in and to all the assets of every kind and
description used in or pertaining to the Practice, including but not limited to
the assets set forth on Exhibit A.  When used in this Agreement, the term
"Stock" shall mean all of Prospect Medical Group's right, title, interest and
estate in and to all of the issued and outstanding stock in Group, including any
rights to any additional stock, preemptive rights, warrants, and the like, as
set forth on Exhibit B.

     D.   Prospect Medical Group, Group and Prospect Medical Systems desire to
enter into this Agreement to incorporate within the terms of one agreement all
of the amendments previously made and to be made as of the date of execution
hereof to an Assignable Option Agreement made as of July 14, 1997 (the "Original
Agreement").

     NOW, THEREFORE, in consideration of the foregoing promises and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged by the parties, Group, Prospect Medical Group, and Prospect Medical
Systems agree as follows:

1.   GRANT OF OPTION.

     1.1  Prospect Medical Group hereby grants to Prospect Medical Systems an
assignable option to purchase all or any part of the Assets (the "Assets
Option"), on the terms and subject to the conditions set forth in this
Agreement.

<PAGE>

     1.2  Group and Prospect Medical Group hereby grant to Prospect Medical
Systems the assignable right to designate a Successor Physician or Successor
Physicians, which person or persons must be duly licensed physicians in the
State of California or otherwise permitted by law to be a shareholder in a
professional corporation, to purchase all or part of the Stock (the "Stock
Option"), on the terms and subject to the conditions set forth herein.  In its
sole discretion, Prospect Medical Systems may designate the amount of Stock
which is to be purchased.  The Assets Option and the Stock Option are
collectively referred to herein as the "Option."

     1.3  Group and Prospect Medical Group represent and warrant that as of the
day and year first above written and during the term of this Agreement, Exhibits
A and B are true and complete listings of the Assets and Stock, respectively, as
revised from time to time pursuant to this Agreement.

     1.4  Other than in connection with that certain Amended and Restated Credit
Succession Agreement, dated as of July 14, 1997, by and among Prospect Medical
Holdings, Inc., a Delaware corporation, Prospect Medical Group, Gregg DeNicola,
M.D., Group, Prospect Medical Systems, Inc., a Delaware corporation, and
Imperial Bank, a California banking corporation ("Imperial"), as amended (the
"Amended and Restated Credit Succession Agreement"), Group shall not recognize
any share transfer or other action not in compliance with the terms of this
Agreement.

2.   TERM OF AGREEMENT.  The term of this Agreement commences as of the day and
year first above written and continues for thirty (30) years ("Term").  So long
as the term of the Management Services Agreement, made and entered into as of
even date herewith, by and between Prospect Medical Systems and Group (the
"Management Services Agreement"), is automatically extended pursuant thereto,
the term of this Agreement shall be automatically extended for additional
coextensive terms of ten (10) years each.  In the event the Management Services
Agreement is terminated pursuant to its terms, this Agreement shall terminate
upon the effective date of termination of said Management Services Agreement.

3.   OPTION PRICE.  The purchase price for the Option (the "Option Price") is
One Hundred Dollars ($100) and Group and Prospect Medical Group acknowledge
receipt of such payment.

4.   EXERCISE OF OPTION.

     4.1  During the Term of this Agreement, Prospect Medical Systems may elect
to exercise the Option at any time.  In the event of an election by Prospect
Medical Systems to exercise the Option, Prospect Medical Systems may exercise
either the Assets Option or the Stock Option, or both, at Prospect Medical
Systems' sole discretion.

     4.2  Notwithstanding the provisions of Section 4.1, if the Management
Services Agreement is terminated by either party, for any reason, Prospect
Medical Systems' right to exercise the Option is automatically and immediately
exercised as of the termination date of the Management Services Agreement such
that Prospect Medical Systems may exercise either the Assets Option or the Stock
Option, or both, at such time.

                                       2

<PAGE>

     4.3  To the extent that the Assets Option is exercised by Prospect Medical
Systems, Prospect Medical Systems will send Group a written notice (the "Assets
Exercise Notice") specifying the Assets to be purchased.  Prospect Medical
Systems may exercise the Assets Option as many times as Prospect Medical Systems
elects in its sole discretion.

     4.4  To the extent that the Stock Option is exercised by Prospect Medical
Systems, Prospect Medical Systems will send Group a written notice (the "Stock
Exercise Notice") specifying the Stock to be purchased.  Prospect Medical
Systems may designate the Successor Physician(s) who will exercise the Stock
Option as many times as Prospect Medical Systems elects in its sole discretion.

     4.5  The Assets Option and the Stock Option are independent of each other,
and can be exercised at different times during the Term.

     4.6  Prospect Medical Systems may cancel any Assets Exercise Notice or
Stock Exercise Notice at any time.

     4.7  Group and Prospect Medical Group shall cooperate with Prospect Medical
Systems in any due diligence.

5.   ASSIGNMENT OF THE OPTION.  Prospect Medical Systems may elect to assign
either the Assets Option or the Stock Option or both to any person, by a written
assignment, signed by both Prospect Medical Systems and the assignee, which
designates the Assets or Stock.  The assignee shall agree as a condition of the
assignment to be bound by the terms of this Agreement.  Thereafter, only the
assignee named in the assignment shall have the right to exercise the applicable
Assets Option and/or the Stock Option as to the designated Assets and/or Stock,
and that assignee, rather than Prospect Medical Systems, shall enter into a
purchase agreement upon exercise of the Assets Option and/or the Stock Option,
as applicable.  Written notice of any such assignment shall be given by Prospect
Medical Systems to Group and Prospect Medical Group within a reasonable time
period following execution of any assignment pursuant to this Agreement.  When
the context so requires in this Agreement, the term "Prospect Medical Systems"
shall be deemed to refer to an assignee holding an assignment of an Asset Option
or Stock Option, and the terms "party" and "parties" shall be deemed to include
that assignee.

6.   PURCHASE PRICE OF THE ASSETS OR STOCK.

     6.1  PURCHASE PRICE.

          a.   ASSETS PURCHASE PRICE.  The purchase price for the Assets to be
purchased pursuant to the exercise of the Assets Option shall be $1,000 ("Assets
Purchase Price").  The purchase price of any partial purchase of the Assets
shall be a pro-rata percentage of the full Assets Purchase Price.

                                       3

<PAGE>

          b.   STOCK PURCHASE PRICE.  The purchase price for the Stock to be
purchased pursuant to the exercise of the Stock Option shall be $1,000 ("Stock
Purchase Price").  The purchase price of less than all of the issued and
outstanding Stock is a pro-rata percentage of the full Stock Purchase Price.

     6.2  PAYMENT.  For the Assets, Prospect Medical Systems shall pay Group the
Assets Purchase Price at Closing in the form of immediately available funds
transferred by wire to an account at a financial institution designated by
Group.  For the Stock, Prospect Medical Systems shall cause the Successor
Physician to pay Prospect Medical Group the Stock Purchase Price.

     6.3  CLOSING.  The transactions contemplated by this Agreement are to close
forty-five (45) days after the date of either the Assets Exercise Notice or the
Stock Exercise Notice, as the case may be ("Closing"), unless extended by
Prospect Medical Systems.

     9.14 DISPUTE RESOLUTION.  In the event the parties hereto are unable to

agree to arbitrate as set forth below.

          a.   There shall be one arbitrator.  If the parties shall fail to

retired judge sitting on the Los Angeles, California, Judicial Arbitration

by the arbitrator.

which shall be reduced to writing, signed by the arbitrator and mailed to 
each of the parties and their legal counsel.

          d.   All decisions of the arbitrator shall be final, binding and 
conclusive on the parties and shall constitute the only method of resolving

execution to enforce the arbitrator's judgment.  Judgment may be entered upon 
such a decision in accordance with applicable law in any court having 
jurisdiction thereof.

          e.   Notwithstanding the foregoing, because time is of the essence of
this Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar short term
equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or

Succession Agreement shall control and such conflicting provision herein shall

14th day of July, 1997, by and between Prospect Medical Group, Inc., a

<PAGE>

    NOW, THEREFORE, in consideration of the foregoing premises and other good
and valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, the parties hereto agree as follows.

1.  PHYSICIAN'S COVENANTS.  

    1.1    As a material inducement to Purchaser to enter into the Stock
Purchase Agreement and except as set forth herein, or as permitted under the
Employment Agreement between Physician and Purchaser, Physician shall not
(directly or indirectly through any business, enterprise, venture, partnership,
corporation or any other entity controlled directly or indirectly by Physician
whether alone or as a partner, stockholder, creditor or otherwise) in the
Service Area described in Section 4 below:

           A.     During the term of Physician's employment with Company,

                  (i)    practice medicine, or engage, participate, aid, assist,
or hold any interest in any business or provision of any service which is, or as
of Physician's engagement or participation, would become, competitive with any
aspect of Purchaser's or any of Purchaser's Affiliates' outpatient or other
healthcare services;

                  (ii)   sell, transfer, assign or otherwise permit another
party to benefit from, any remaining goodwill attributable to Physician based
upon the provision of physician services by or through Physician;

                  (iii)  engage or contract (other than with Purchaser or any of
Purchaser's Affiliates) for the provision of any management services to
Physician or any physician employed or under contract to Physician (as
applicable) which are the same as or substantially similar to any of the
services that Purchaser furnishes;

                  (iv)   commit any other act or assist others to commit any
other act which might injure the business of Purchaser or Purchaser's
Affiliates;

           B.     During the term of Physician's employment with Company and for
a period of two (2) years thereafter,

                  (i)    solicit or assist any other person to solicit any
business relating to a competing line of business (other than for Purchaser or
any of its affiliates) from any present or potential customer (including all
third party payors) of Physician, Seller, Purchaser, or any of their affiliates;

                  (ii)   directly or indirectly employ, contract, solicit or
encourage any employee or other person under contract with Purchaser or any of
its Affiliates to leave the employ of any such entity, except pursuant to the
terms of the Stock Purchase Agreement; and


                                          2
<PAGE>

                  (iii)  directly or indirectly solicit, request, advise, or
encourage any present or future supplier, customer, patient or employee of
Purchaser or its Affiliates (including practices managed by Purchaser) to
withdraw, curtail, disenroll, or become enrolled with another provider of health
care, or cancel its business dealings with Purchaser or its affiliates, or take
any actions that might impair the relations of Purchaser or any of its
affiliates and their respective suppliers, customers, employees or others.

    1.2    If any term or provision of this Section is determined to be illegal,
unenforceable or invalid in whole or in part for any reason, such illegal,
unenforceable or invalid provision or part thereof shall be stricken from this
Agreement, and such provision shall not affect the legality, enforceability or
validity of the remainder of this Agreement.  If any provision or part thereof
of this Agreement is stricken from this Agreement, in accordance with the
provisions of this Section, then the stricken provision shall automatically be
replaced to the extent possible, with a legal, enforceable and valid provision
which is as similar in tenor to the stricken provision as is legally possible.

2.  CONFIDENTIALITY.  From and after the Closing Date, Physician shall keep
secret and retain in strictest confidence, and shall not use for the benefit of
any other party, except for Purchaser or any of Purchaser's Affiliates, trade
secrets known to Physician relating to the business and operations of Physician,
Seller, Purchaser or any of their affiliates, including without limitation,
customer lists, utilization data, patient records, business acquisition plans,
relating to the business and operations of Physician, Seller, Purchaser or any
of their affiliates learned by Physician before or after the date of this
Agreement, and shall not disclose them to anyone outside of Purchaser and its
Affiliates, provided however, that this section shall not apply to information
in the public domain or to information that is sought from Physician pursuant to
subpoena or court order (but Physician must provide notice to Purchaser or its
Affiliates in order for them to contest such subpoenas or court orders).

3.  PHYSICIAN'S REPRESENTATION.  Physician specifically acknowledges,
represents, and warrants that (i) Physician's covenants set forth in this
Agreement are being purchased in connection with the sale of the Stock to
Purchaser, (ii) such covenants are reasonable and necessary to protect the
legitimate interests of Purchaser, and (iii) Purchaser would not have entered
into the Stock Purchase Agreement in the absence of such restrictions. 
Physician acknowledges that this Agreement is subject to all representations,
warranties and covenants in the Stock Purchase Agreement.

4.  SERVICE AREA.  The Service Area to which Physician's covenants in Section 1
applies is  set forth in Exhibit A attached hereto.

5.  TERM.  Except for the provisions contained in Section 1.1.B, the term of
this Agreement commences as of the day and year first above written and
terminates upon the earlier to occur of:

           (i)    the termination of Physician's employment under the Employment
Agreement; or


                                          3
<PAGE>

           (ii)   the date on which the Stock Purchase between Purchaser and
Physician is terminated due to a "Jeopardy Event" as defined in Section 10.1 of
the Stock Purchase Agreement; or

           (iii)  the date upon which Employer is in material default of any of
Employer's obligations under its Employment Agreement with Physician or the
Stock Purchase Agreement, and Physician terminates the Employment Agreement as a
result of such material breach.  In the event of termination of Physician's
Employment Agreement by Physician for cause, as set forth therein, Employer
shall be required to pay to Physician the remaining compensation and benefits
owed under the Employment Agreement at such times as if the Employment Agreement
were still in full force and effect.

6.  MISCELLANEOUS.

    A.     SUCCESSORS AND ASSIGNS.  This Agreement shall be binding upon and
shall inure to the benefit of the parties and their respective heirs (as
applicable), legal representatives, and permitted successors and assigns.  No
party may assign this Agreement or the rights, interests or obligations
hereunder.  Any assignment or delegation in contravention of this Section shall
be null and void.

    B.     MEDICAL STAFF PRIVILEGES.  Nothing in this Agreement is intended to
prohibit Physician from maintaining professional staff membership or clinical
privileges at any acute care hospital or other health facility licensed to
provide patient care for stays in excess of twenty-four (24) hours, so long as
maintaining such privileges does not in any manner result in Physician competing
with Employer in the Service Area.

    C.     COUNTERPARTS.  This Agreement, and any amendments thereto, may be
executed in counterparts, each of which shall constitute an original document,
but which together shall constitute one and the same instrument.

    D.     HEADINGS.  The section headings contained in this Agreement are
inserted for convenience only and shall not affect in any way the meaning or
interpretation of this Stock Purchase Agreement.

    E.     STOCKHOLDER IN PUBLIC COMPANY.  Notwithstanding any provision to the
contrary, nothing contained herein shall prevent Physician from purchasing or
otherwise acquiring equity securities of a company that has a class of
securities traded on a national securities exchange whose business competes with
that of the Company, so long as Physician's ownership of such securities does
not exceed one percent (1%) of the total outstanding shares of such competitive
company.

    F.     AMENDMENT.  This Agreement may not be amended except in writing and
as executed by all parties.


                                          4

    I.     GOVERNING LAW.  This Agreement shall be governed by and construed in
accordance with the laws of the State of California.

    J.     SEVERABILITY.  If any provision or portion of this Agreement is held
by a court of competent jurisdiction to be invalid or unenforceable, the
remainder of this Agreement will nevertheless continue in full force and effect
and shall not be invalidated or rendered unenforceable or otherwise adversely
affected, unless such invalidity or unenforceability would defeat an essential
business purpose of this Stock Purchase Agreement.  Without limiting the
generality of the foregoing, if the provisions of this Agreement shall be deemed
to create a restriction which is unreasonable as to either duration or
geographical area, or both, the parties agree that the provisions of this
Agreement shall be enforced for such duration and in such geographical area as
any court of competent jurisdiction may determine to be reasonable.

    K.     ARBITRATION. The parties firmly desire to resolve all disputes
arising hereunder without resort to litigation in order to protect their
respective business reputations and the 


                                          5
<PAGE>

confidential nature of certain aspects of their relationship.  Accordingly, any
controversy or claim arising out of or relating to this Agreement, or the breach
thereof, shall be settled by arbitration as set forth below.

           (i)    All disputes which in any manner arise out of or relate to
this Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section K.  Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

           (ii)   The parties stipulate to arbitration before a single, mutually
agreed upon arbitrator sitting on the Los Angeles, California Judicial
Arbitration Mediation Services (JAMS) panel.  In the event that the parties are
unable to agree upon the person chosen as arbitrator within 30 days of the
demand for arbitration, the arbitrator shall be selected in the sole discretion
of the JAMS administrator.  The arbitrator shall be a member of the California
bar.

           (iii)  The parties shall share all costs of arbitration.  The
prevailing party shall be entitled to reimbursement by the other party of such
party's attorneys' fees and costs and any arbitration fees and expenses incurred
in connection with the arbitration hereunder.

           (iv)   The substantive law of the State of California shall be
applied by the arbitrator.  All proceedings in arbitration shall be in
accordance with the California Code of Civil Procedure, as amended, and the
parties shall have the right to legal discovery in any matter submitted to
arbitration in satisfaction of California Code of Civil Procedure Section
1283.05, as permitted by California Code of Civil Procedure Section 1283.1(b).

           (v)    Arbitration shall take place in Los Angeles, California unless
the parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable thereafter, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

           (vi)   All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement.  The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

           (vii)  Notwithstanding the foregoing, because time is of the essence
of this Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar equitable
relief.

           (viii) The decision and award of the arbitrator shall be kept
confidential by the 


                                          6
<PAGE>

parties to the greatest extent possible.  No disclosure of such decision or
award shall be made by the parties except as required by law or as necessary or
appropriate to effect the enforcement thereof.

           (ix)   Should either Employer or Physician institute any action or
procedure to enforce this Agreement or any provision hereof, or for damages by
reason of any alleged breach of this Agreement or of any provision hereof, or

                     PERSONAL GUARANTY OF PAYMENT AND PERFORMANCE

     THIS PERSONAL GUARANTY OF PAYMENT AND PERFORMANCE ("Guaranty"), is made as
of July 14, 1997, by Melvin L. Reich, D.O. ("Guarantor"), whose address is 4603
Seashore Drive, Newport Beach, California 92663, in favor of Prospect Medical
Group, Inc., a California professional corporation ("Purchaser"), whose address
is 18200 Yorba Linda Blvd., Suite 409, Yorba Linda, California 92686.

                                     WITNESSETH:

     WHEREAS, Guarantor is the sole shareholder of Santa Ana/Tustin Physicians
Group, Inc., a California professional corporation ("Company"); and

     WHEREAS, Purchaser is acquiring all of the shares of Company pursuant to
the terms of that certain Agreement for the Purchase and Sale of Stock, dated
June 23, 1997, by and among Purchaser, Company and Guarantor ("Stock Purchase
Agreement"); and

     WHEREAS, Company, Guarantor, and Purchaser are also willing to enter into
certain ancillary agreements in the form attached as exhibits to the Stock
Purchase Agreement (the term "Stock Purchase Agreement" includes the exhibits,
schedules and ancillary agreements to be delivered at Closing; all capitalized
terms are as defined in the Stock Purchase Agreement unless otherwise defined
herein); and

     WHEREAS, Guarantor makes certain representations, warranties, indemnities,
and covenants in the Stock Purchase Agreement, relating to the payment and
performance of certain liabilities and claims of Company which occurred or arose
prior to the Closing Date from the Reserve Account (collectively, the
"Obligations"); and

     WHEREAS, to the extent that the Reserve Account is insufficient to provide
for the payment of such Obligations, Guarantor is willing to guarantee the
Obligations to induce Purchaser to enter into the Stock Purchase Agreement;

     NOW, THEREFORE, to induce Purchaser to enter into the Stock Purchase
Agreement and in consideration of the foregoing promises and for other good and
valuable consideration, the receipt and sufficiency of which are hereby
acknowledged, Guarantor hereby covenants and agrees for the benefit of
Purchaser, as follows:

1.   GUARANTY.

     1.1    Notwithstanding anything to the contrary contained in this Guaranty,
pursuant to the terms of the Stock Purchase Agreement, in the event Purchaser is
required to provide for the payment of any Obligation, Purchaser is required to
exhaust all sums in the Reserve Account prior to making a demand upon Guarantor
for payment.  In the event that the funds in the Reserve Account are
insufficient to pay any or all claims or liabilities of Company which were
incurred 

<PAGE>

prior to the Closing Date for which payment has not already been made, Guarantor
does hereby unconditionally and irrevocably guarantee to Purchaser the full and
prompt performance of the Obligations when such performance is due on a
dollar-for-dollar, after-tax basis (with such tax effects to be determined
within 20 days of the completion of an audit of Company's financial statements
for the first fiscal period following the Closing Date), including but not
limited to payment for breach of any of the Obligations.  Purchaser and
Guarantor agree that Guarantor's liability for the Obligations shall be limited
to $1,000,000, exclusive of any amounts in the Reserve Account; provided
however, that the following shall not count toward such $1,000,000 limitation: 
(i) any Obligation known by Guarantor to exist at the time of the execution of
the Stock Purchase Agreement which was not disclosed to Purchaser, or (ii)
Obligations resulting from fraud, tax liabilities, or a violation of state or
federal statutes or regulations governing the practice of medicine.

     1.2    Subject to the limitations of Section 4 of this Guaranty, Guarantor
hereby agrees that if any performance of the Obligations is not rendered in
accordance with their terms for any reason whatsoever, Guarantor shall
immediately make such payments and performance.  Guarantor further agrees to pay
Purchaser all expenses (including, without limitation, reasonable attorneys'
fees) paid or incurred by Purchaser in endeavoring to obtain performance of the
Obligations, to enforce any other obligations guaranteed hereby, or to enforce
this Guaranty.

2.   REINSTATEMENT OF OBLIGATIONS.  If at any time all or any part of any
payment or performance made by Guarantor or received by Purchaser from Guarantor
under or with respect to this Guaranty is or must be rescinded or returned for
any reason whatsoever (including, but not limited to, the insolvency, bankruptcy
or reorganization of Guarantor or Company), then the obligations of Guarantor
hereunder shall, to the extent of the payment or performance rescinded or
returned, be deemed to have continued in existence, notwithstanding such
previous payment or performance made by Guarantor, or receipt of payment or
performance by Purchaser, and the obligations of Guarantor hereunder shall
continue to be effective or be reinstated, as the case may be, as to such
payment or performance, all as though such previous payment or performance by
Guarantor had never been made.

3.   WAIVERS BY GUARANTOR.  To the extent permitted by law, Guarantor hereby
waives and agrees not to assert or take advantage of (as a defense or otherwise)
any one or more of the following:

     3.1    Except as provided in Section 1.1 herein, any right to require
Purchaser to proceed against Company or any other person or to proceed against
or exhaust any security held by Purchaser at any time or to pursue any other
remedy in Purchaser's power or under any other agreement before proceeding
against Guarantor hereunder; and any right or claim or right to cause a
marshaling of the assets of Guarantor;

     3.2    Any defense arising from the failure of Purchaser (i) to file or
enforce a claim against the estate (in administration, bankruptcy or any other
proceeding) of any other person or 


                                          2
<PAGE>

persons; (ii) to ascertain the extent or nature of the Collateral or other
rights with respect thereto, or the liability of any liable party or the
obligations evidenced or secured thereby; and

     3.3    An assertion or claim that the automatic stay provided by 11 U.S.C.
Section 362 (arising upon the voluntary or involuntary bankruptcy proceeding of
Company) or any other stay provided under any other debtor relief law (whether
statutory, common law, case law or otherwise) of any jurisdiction whatsoever,
now or hereafter in effect, which may be or become applicable, shall operate or
be interpreted to stay, interdict, condition, reduce or inhibit the ability of
Purchaser to enforce any of its rights, whether now or hereafter required, which
Purchaser may have against Guarantor.

4.   TERM.  The term of this Guaranty shall be three (3) years from the date
hereof, except for (i) any Obligation known by Guarantor to exist at the time of
the execution of the Stock Purchase Agreement which was not disclosed to
Purchaser, or (ii) Obligations resulting from fraud, tax liabilities, or a
violation of state or federal statutes or regulations governing the practice of
medicine, in which case the Guaranty shall continue.

5.   GENERAL PROVISIONS.

     5.1    FULL RECOURSE.  Except as provided in Section 1.1 herein concerning
the requirement that Purchaser first exhaust all sums in the Reserve Account
prior to making demand on Guarantor, or in Section 4 covering the term of this
Guaranty, all of the terms and provisions of this Guaranty are recourse
obligations as to  Guarantor and not restricted by any limitation on personal
liability.

     5.2    KNOWLEDGE OF COMPANY AND COMPANY'S SHAREHOLDER.  As the sole
shareholder, director, and officer of Company prior to the Closing, Guarantor
warrants and represents that  Guarantor is fully aware of the financial and
other conditions and status of Company and is executing and delivering this
Guaranty based solely upon Guarantor's own knowledge and independent
investigation of all matters pertinent hereto, and that Guarantor is not relying
in any manner upon any representation or statement of Purchaser, except as set
forth in the Stock Purchase Agreement.  Guarantor warrants, represents and
agrees that Guarantor is in a position to obtain, and Guarantor hereby assumes
full responsibility for obtaining, any additional information concerning the
financial and other conditions and status of Company and any other matter
pertinent hereto, and that Guarantor is not relying upon Purchaser to furnish,
and shall have no right to require Purchaser to obtain or disclose, any
information with respect to the Obligations guaranteed hereby, the financial
condition or character of Company or the ability of Company to pay or perform
the Obligations guaranteed hereby, the existence of any security for any or all
of such indebtedness or obligations, the existence or nonexistence of any other
guaranties of all or any part of such indebtedness or obligations, any actions
or non-action on the part of Purchaser, Company or any other person or entity,
or any other matter, fact or occurrence whatsoever.  By executing this Guaranty,
Guarantor acknowledges and knowingly accepts the full range of risks encompassed
within a contract of guaranty.


                                          3
<PAGE>

     5.3    SURVIVAL/BREACH BY PURCHASER.  Except for a material breach by
Purchaser of a provision of the Stock Purchase Agreement and Employment
Agreement, and subject to the term set forth herein, this Guaranty shall be and
shall remain in full force and effect and shall survive the exercise of any
remedy by Purchaser under law, in equity, and under the Stock Purchase
Agreement, including, without limitation, any foreclosure or deed in lieu
thereof.  In the event of a material breach by Purchaser of a provision of the
Stock Purchase Agreement or the Employment Agreement, the obligations, waivers
and subrogation of Guarantor hereunder shall be suspended until such breach is
cured.

     5.4    RESERVATION OF RIGHTS.  Nothing contained in this Guaranty shall
prevent or in any way diminish or interfere with any rights or remedies,
including, without limitation, the right to contribution, which Purchaser may
have against Company, Guarantor or any other party under any applicable federal,
state or local laws, all such rights being hereby expressly reserved.

     5.5    RIGHTS CUMULATIVE.  Purchaser's rights under this Guaranty shall be
in addition to all rights of Purchaser under law, in equity, and any other
agreement.

     5.6    MITIGATION.  Purchaser must act in good faith to mitigate any
damages or costs suffered as a result of Guarantor's failure to perform the
Obligations.

     5.7    ENTIRE AGREEMENT; AMENDMENT; SEVERABILITY.  Except as set forth in
the Stock Purchase Agreement, this Guaranty contains the entire agreement
between the parties respecting the matters herein set forth and supersedes all
prior agreements, whether written or oral, between the parties respecting such
matters; and Guarantor and Purchaser acknowledge that there are no
contemporaneous oral agreements with respect to the subject matter hereof.  This
Guaranty may not be changed, modified or amended, except by a writing executed
by the parties hereto; and no obligation of Guarantor can be released or waived
by Purchaser or any agent of Purchaser, except by a writing duly executed by
Purchaser.  A determination that any provision of this Guaranty is unenforceable
or invalid shall not affect the enforceability or validity of any other
provision, and any determination that the application of any provision of this
Guaranty to any person or circumstance is illegal or unenforceable shall not
affect the enforceability or validity of such provision as it may apply to any
other persons or circumstances.

     5.8    GOVERNING LAW; BINDING EFFECT; ASSIGNMENT; WAIVER OF ACCEPTANCE. 
This Guaranty shall be governed by and construed in accordance with the laws of
the State of California, except to the extent that the applicability of any of
such laws may now or hereafter be preempted by Federal law, in which case such
Federal law shall so govern and be controlling.  The provisions of this Guaranty
shall be binding upon Guarantor and its respective heirs, executors, legal
representatives, successors and assigns and shall inure to the benefit of
Purchaser, the heirs, executors, legal representatives, successors and assigns
of Purchaser.  This Guaranty shall in no event be impaired by any change which
may arise by reason of the death of Guarantor or by reason of the dissolution of
Company.  Except for an assignment to St. Joseph's Hospital Systems, St Joseph's
Foundation, St. Joseph's Medical Corporation, or any of their affiliates, this
Guaranty is assignable by Purchaser with Seller's consent, which consent shall
not 


                                          4
<PAGE>

be unreasonably withheld, and any full or partial assignment hereof by Purchaser
shall operate to vest in the assignee all rights and powers herein conferred
upon and granted to Purchaser and so assigned by Purchaser.  Guarantor expressly
waives notice of transfer or assignment of this Guaranty and acknowledges that
the failure by Purchaser to give any such notice shall not affect the
liabilities of  Guarantor hereunder.  Notwithstanding the foregoing, Guarantor
shall not assign any of its rights or obligations under this Guaranty. 
Guarantor hereby waives any acceptance of this Guaranty by Purchaser, and this
Guaranty shall immediately be binding upon Guarantor.

     5.9    NOTICES.  All notices, demands, requests or other communications to
be sent by one party to the other hereunder or required by law shall be in
writing and shall be deemed to have been validly given or served by delivery of
the same in person to the intended addressee, or by depositing the same with
Federal Express or another reputable private courier service for next business
day delivery to the intended addressee at its address set forth on the first
page of this Guaranty or at such other address as may be designated by such
party as herein provided, or by depositing the same in the United States mail,
postage prepaid, registered or certified mail, return receipt requested,
addressed to the intended addressee at its address set forth on the first page
of this Guaranty or at such other address as may be designated by such party as
herein provided.  All notices, demands and requests shall be effective upon such
personal delivery, or one (1) business day after being deposited with the
private courier service, or two (2) business days after being deposited in the
United States mail as required above.  Rejection or other refusal to accept or
the inability to deliver because of changed address of which no notice was given
as herein required shall be deemed to be receipt of the notice, demand or
request sent.  By giving to the other party hereto at least fifteen (15) days'
prior written notice thereof in accordance with the provisions hereof, the
parties hereto shall have the right from time to time to change their respective
addresses and each shall have the right to specify as its address any other
address within the United States of America.

     5.10   NO WAIVER; TIME OF ESSENCE; BUSINESS DAY.  The failure of any party
hereto to enforce any right or remedy hereunder, or to promptly enforce any such
right or remedy, shall not constitute a waiver thereof nor give rise to any
estoppel against such party nor excuse any of the parties hereto from their
respective obligations hereunder.  Any waiver of such right or remedy must be in
writing and signed by the party to be bound.  This Guaranty is subject to
enforcement at law or in equity, including actions for damages or specific
performance.  All damages sought shall be on a dollar-for-dollar, after-tax
basis, with such tax effects to be determined within 20 days of the completion
of an audit of Company's financial statements for the first fiscal period
following the Closing Date..  Time is of the essence hereof.  The term "business
day" as used herein shall mean a weekday, Monday through Friday, except a legal
holiday.

     5.11   SUCCESSIVE ACTIONS.  A separate right of action hereunder shall
arise each time Purchaser acquires knowledge of any failure of payment or
performance of any matter guaranteed by Guarantor under this Guaranty.  Separate
and successive actions may be brought hereunder to enforce any of the provisions
hereof at any time and from time to time.  No action hereunder shall preclude
any subsequent action, and Guarantor hereby waives and covenants not to assert
any defense in the nature of splitting of causes of action or merger of
judgments.


                                          5
<PAGE>

6.   ARBITRATION.  The parties firmly desire to resolve all disputes arising
hereunder without resort to litigation in order to protect their respective
business reputations and the confidential nature of certain aspects of their
relationship.  Accordingly, any controversy or claim arising out of or relating
to this Agreement, or the breach thereof, shall be settled by arbitration as set
forth below.

     6.1    All disputes which in any manner arise out of or relate to this
Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 6.  Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

     6.2    The parties stipulate to arbitration before a single, mutually
agreed upon arbitrator sitting on the Los Angeles, California Judicial
Arbitration Mediation Services (JAMS) panel.  In the event that the parties are
unable to agree upon the person chosen as arbitrator within 30 days of the
demand for arbitration, the arbitrator shall be selected in the sole discretion
of the JAMS administrator.  The arbitrator shall be a member of the California
bar.

     6.3    The parties shall share all costs of arbitration.  The prevailing
party shall be entitled to reimbursement by the other party of such party's
attorneys' fees and costs and any arbitration fees and expenses incurred in
connection with the arbitration hereunder.

     6.4    The substantive law of the State of California shall be applied by
the arbitrator.  All proceedings in arbitration shall be in accordance with the
California Code of Civil Procedure, as amended, and the parties shall have the
right to legal discovery in any matter submitted to arbitration in satisfaction
of California Code of Civil Procedure Section 1283.05, as permitted by
California Code of Civil Procedure Section 1283.1(b).

     6.5    Arbitration shall take place in Los Angeles, California unless the
parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable thereafter, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

     6.6    All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement.  The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

     6.7    Notwithstanding the foregoing, because time is of the essence of
this Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar equitable
relief.


                                          6
<PAGE>

     6.8    The decision and award of the arbitrator shall be kept confidential
by the parties to the greatest extent possible.  No disclosure of such decision
or award shall be made by the parties except as required by law or as necessary
or appropriate to effect the enforcement thereof.

     6.9    Should either Employer or Physician institute any action or
procedure to enforce this Agreement or any provision hereof, or for damages by
reason of any alleged breach of this Agreement or of any provision hereof, or
for a declaration of rights hereunder (including without limitation
arbitration), the prevailing party in any such action or proceeding shall be
entitled to receive from the other party all costs and expenses, including
without limitation reasonable attorneys' fees, incurred by the prevailing party
in connection with such action or proceeding.

     IN WITNESS WHEREOF, the undersigned Guarantor has executed this Guaranty as
of the day and year first above written.

                                   DR. JACOB TERNER
                                  PERSONAL GUARANTY
                                          OF
                               PAYMENT AND PERFORMANCE


     THIS GUARANTY OF REPAYMENT AND PERFORMANCE (the "Guaranty") is made and
entered into and effective this 23rd day of June, 1997 by and between Jacob Y.
Terner, M.D. and Santa Ana/Tustin Physicians Group, Inc., a California
Professional Corporation ("Company") and Melvin L. Reich, D.O. ("Reich").
Capitalized terms not used herein and not otherwise defined herein shall have
the meanings assigned to them in that certain Agreement For the Purchase and
Sale of Stock of Santa Ana/Tustin Physicians Group, Inc. ("Stock Purchase
Agreement") of even date herewith by and among Purchaser, Company, and Reich.

                                       RECITALS

     A.   WHEREAS, pursuant to the terms of the Stock Purchase Agreement,
Purchaser is purchasing from Reich, all the issued and outstanding shares of the
Company for the aggregate consideration of Five Million Dollars ($5,000,000).

     B.   WHEREAS, Section 8.5(j) of the Stock Purchase Agreement provides that
in the event Purchaser does not timely make any payment when due, Terner shall
personally fund up to One Million Dollars ($1,000,000) of the Purchase Price.

     C.   WHEREAS, as additional security for the payment of the Purchase Price
and as a condition to the sale of the outstanding shares of the Company,
Purchaser is required by the Stock Purchase Agreement to have Terner execute and
deliver to Reich this Guaranty.

                                      AGREEMENT

     NOW, THEREFORE, in consideration of the foregoing, and of the mutual
covenants, conditions, agreements, representations and warranties hereinafter
contained and such other good and valuable consideration, the legal sufficiency
of which is acknowledged by Terner, the parties hereto agree as follows:

     1.   GUARANTY OF REPAYMENT AND PERFORMANCE.  Terner hereby acknowledges
receipt of good, adequate, legal and valuable consideration including but not
limited to the fact that (i) Terner owns directly a cash equity interest in
Prospect Medical Holdings which will receive revenue from the Company based upon
a management agreement between the Company and Prospect Medical Holdings and
(ii) Terner not having to be the buyer for this acquisition.  In the event
Purchaser does not timely pay any portion of the Purchase Price when due, as set
forth in the Stock Purchase Agreement, upon five (5) days prior written notice
from Reich, Terner hereby


<PAGE>


agrees to personally pay up to $1,000,000 of such amount (the "Guarantee
Amount") to Reich, on behalf of Purchaser.  Reich agrees and acknowledges that
Terner's obligation to pay up to the Guarantee Amount shall not arise until such
time as Prospect does not timely make any payment required under the Stock
Purchase Agreement.  Notwithstanding the foregoing, Terner's obligations
hereunder shall only arise if Purchaser has already deposited $1,900,000 into
the Escrow Account at the time the Escrow Account is opened and shall not arise
until forty two (42) days from the date of execution of the Stock Purchase
Agreement unless Purchaser elects to close earlier than forty two (42) days from
the execution date of this Stock Purchase Agreement in which event Terner's
obligations under this Guaranty shall commence the Closing Date.  Terner's
liability hereunder shall be in an amount up to the Guarantee Amount plus
interest, costs, and fees including reasonable attorney fees incurred in the
enforcement of the Guarantee including those that would have accrued under the
Stock Purchase Agreement but for the commencement of a case under Title 11 of
the United States Bankruptcy Code (the "Bankruptcy Code") or any other law
governing insolvency, bankruptcy, reorganization, liquidation or like
proceeding.  Terner's liability under this Guaranty is a guaranty of performance
and payment of the Guarantee Amount and not of collectability.  In the event of
any breach of any of the terms and conditions of the Stock Purchase Agreement by
Reich, Terner's performance under this Guaranty shall be suspended until such
breach is cured.

     2.   CHANGES DO NOT AFFECT LIABILITY.  Reich may without notice to Terner
and in his absolute discretion and without prejudice to him or in any way
limiting Terner's liability under this Guaranty, (a) grant extensions of time,
renewals or other indulgences and modifications to Terner or Prospect or any
other party under the Stock Purchase Agreement and all documents related thereto
or evidencing the transactions set forth in the Stock Purchase Agreement
(collectively, the "Stock Purchase Documents"), (b) change, amend or modify the
Stock Purchase Documents, (c) discharge or release any party or parties liable
under the Stock Purchase Documents, (d) accept or make compositions or other
arrangements or file or refrain from filing a claim in any bankruptcy proceeding
of Purchaser or any other guarantor or pledgor, (e) credit payments in such a
manner and order of priority to principal, interest or other obligations as
Reich may determine in his discretion, and (g) otherwise deal with Purchaser or
any party related to the transactions set forth in the Stock Purchase Documents.
Without limiting the generality of the foregoing, Terner hereby waives the
rights and benefits under CC Section 2819 and agrees that by doing so Terner's
liability shall continue even if Reich alters any obligations under the Stock
Purchase Documents in any respect or Reich's remedies or rights against
Purchaser are in any way impaired or suspended without Terner's consent.

     3.   WAIVERS OF CERTAIN RIGHTS AND DEFENSES.  Except as provided in the
next paragraph, Terner hereby waives any and all benefits and defenses under CC
Section 2845, 2849 and 2850, including, without limitation, the right to require
Reich to (a) proceed against Purchaser or any other guarantor or pledgor and
without proceeding against or exhausting any security or collateral Reich holds.
Terner agrees that Reich may unqualifiedly exercise in its sole


                                          2
<PAGE>

discretion any or all rights and remedies in enforcing this Guaranty, under
which Terner's liabilities shall remain independent and unconditional.  Terner
agrees that Reich's exercise of certain of such rights or remedies may affect or
eliminate Terner's right of subrogation or recovery against Purchaser and that
Terner may incur a partially or totally nonreimbursable liability under this
Guaranty.

     4.   ADDITIONAL WAIVERS.  Terner hereby waives diligence and all demands,
protests, presentments and notices of every kind or nature, including notices of
protest, dishonor, nonpayment, acceptance of this Guaranty and the creation,
renewal, extension, modification or accrual of any of the obligations Terner has
hereby guarantied.  No failure or delay on Reich's part in exercising any power,
right or privilege hereunder shall impair any such power, right or privilege or
be construed as a waiver of or an acquiescence therein.  Terner hereby waives
any defense to the enforcement of this Guaranty based upon the lack of
consideration in whole or in part.

     5.   GUARANTY MADE WITH FULL KNOWLEDGE.  Terner has had the opportunity to
review matters discussed and contemplated by the Stock Purchase Documents,
including the remedies Reich may pursue against Purchaser in the event of a
default under the Stock Purchase Documents and Purchaser's financial condition
and ability to perform under the Stock Purchase Documents.  Terner further
agrees to keep himself fully informed on all aspects of Purchaser's  financial
condition and the performance of Purchaser's obligations to Reich and that Reich
has no duty to disclose to Terner any information pertaining to Purchaser or any
security of collateral.

     9.   ARBITRATION.  The parties firmly desire to resolve all disputes
arising hereunder without resort to litigation in order to protect their
respective business reputations and the confidential nature of certain aspects
of their relationship.  Accordingly, any controversy or claim arising out of or
relating to this agreement or the breach thereof, shall be settled by
arbitration as set forth below.

          9.1  All disputes in any manner arise out of or relate to this
Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 10.  Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

          9.2  The parties stipulate to arbitration before a single, mutually
agreed upon arbitrator sitting on the Los Angeles, California Judicial
Arbitration Mediation Services (JAMS) panel.  In the event that the parties are
unable to agree upon the person chosen as arbitrator within 30 days of the
demand for arbitration, the arbitrator shall be selected in the sole discretion
of the JAMS administrator.  The arbitrator shall be a member of the California
bar.

          9.3  The parties shall share all costs of arbitration.  The prevailing
party shall be entitled to reimbursement by the other party of such party's
attorneys' fees, and costs and any arbitration fees and expenses incurred in
connection with the arbitration hereunder.

          9.4  The substantive law of the State of California shall be applied
by the arbitrator.  All proceedings in arbitration shall be in accordance with
the California Code of Civil Procedure, as amended, and the parties shall have
the right to legal discovery in any matter submitted to arbitration in
satisfaction of California Code of Civil Procedure Section 1283.05, as permitted
by California Code of Civil Procedure Section 1283.1(b).

          9.5  Arbitration shall take place in Los Angeles, California unless
the parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable


                                          4
<PAGE>

thereafter, the arbitrator shall arrive at a final decision, which shall be
reduced to writing, signed by the arbitrator and mailed to each of the parties
and their legal counsel.

          9.6  All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement.  The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrator's judgement.  Judgement may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

          9.7  Notwithstanding the foregoing, because time is of the essence of
this Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar short term
equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or
dissolve such court order.

          9.8  The decision and award of the arbitrator shall be kept
confidential by the parties to the greatest extent possible.  No disclosure of
such decision or award shall be made by the parties except as required by law or
as necessary or appropriate to effect the enforcement thereof.

          9.9  In the event of any dispute concerning this guaranty, the
prevailing party in any such action or proceeding shall be entitled to receive
from the other party all costs and expenses, including without limitation
reasonable attorneys' fees, incurred by the prevailing party in connection with
such action or proceeding.

<PAGE>

                                      AGREEMENT


     1.   PREMISES.  Pursuant to the Master Lease specified below, Manager shall
provide adequate GROUP administrative office space at the addresses described
therein (the "Premises") and facilities for the operation of the Practice with
leasehold improvements, auxiliary services and utilities in order that GROUP may
effectively perform its functions and duties.

          In consideration of the sums to be paid to Manager under the terms of
this Agreement, Manager hereby leases to GROUP during the term of this Agreement
the facilities and leasehold improvements at the Premises and the furniture,
fixtures and equipment (the "FF&E") listed on Exhibit "B" attached hereto and
incorporated herein by this reference, under the following terms and conditions:

          1.1.    Manager is the lessee, or will become lessee, under certain
leases for the Premises (hereinafter collectively referred to as the "Master
Lease") copies of which are attached hereto as Exhibit "A" and incorporated
herein by this reference.  GROUP hereby acknowledges that the Premises described
in the Master Lease are suitable for the administrative office of the Practice.
Based and contingent upon GROUP's promise to timely pay all amounts due under
this Agreement, Manager hereby agrees to sublease the leased Premises to GROUP
upon the following terms and conditions:

                  1.1.1.    This sublease between Manager and GROUP of the
Premises shall be subject to all of the terms and conditions of the Master
Lease.  In the event of the termination of Manager's interest as lessee under
the Master Lease for any reason, then the sublease created hereby shall
simultaneously terminate unless GROUP is willing to assume the obligations under
the Master Lease and the Lessor consents thereto.

                  1.1.2.    All of the terms and conditions contained in the
Master Lease are incorporated herein as terms and conditions of the sublease
(with each reference therein to "Lessor" and "Lessee," to be deemed to refer to
Manager and GROUP, respectively) and, along with the provisions of this Section
1.1 and Exhibit "A," shall be the complete terms and conditions of the sublease
created hereby.

                  1.1.3.    Notwithstanding the foregoing, as between Manager
and GROUP, Manager shall remain responsible for meeting the financial
obligations of "Lessee" under the Master Lease, and GROUP shall have no monetary
obligation in that regard.  In addition, as between Manager and GROUP, Manager
shall retain all rights to exercise any options to purchase the Premises, or
other similar rights of ownership or possession, which may be granted under the
Master Lease, and GROUP shall have no rights in that regard.

                  1.1.4.    In the event this Agreement is terminated according
to its terms, this sublease shall also terminate automatically.


                                          3
<PAGE>

                  1.1.5.    If the Master Lease contains an option to renew the
term thereof, Manager shall notify GROUP, at least thirty (30) days prior to the
expiration of the time for exercising such option, of Manager's intention to
renew or not to renew such term.  If Manager determines not to renew such term,
Manager shall, at GROUP's option and upon the consent of the Landlord in
accordance with the terms of the Master Lease, assign the Master Lease to GROUP,
including Manager's right to renew the term thereof.

     2.   PROVISION OF FURNITURE, FURNISHINGS AND EQUIPMENT ("FF&E").  Manager
hereby provides to GROUP, and GROUP hereby leases from Manager, all the FF&E,
which FF&E GROUP agrees are suitable and sufficient for GROUP's use in the
operation of GROUP's administrative office at the Premises and are generally in
good repair.  The use by GROUP of said FF&E shall be subject to the following
conditions:

          2.1.    Title to all of the FF&E shall remain in Manager at all times,
and upon the termination of this Management Services Agreement, GROUP shall
immediately surrender the FF&E to Manager in as good condition as of the date
hereof, normal wear and tear excepted.  Alternatively, GROUP, in its sole
discretion, shall have the option to purchase any or all of the FF&E upon
termination hereof.  GROUP shall exercise such option, if at all, by giving
Manager written notice of same (the "Notice") within twenty (20) days of the
effective date of termination hereof.  Upon exercise of such option, Manager
shall convey to GROUP within thirty (30) days of the effective date of
termination hereof, all of the FF&E identified in the Notice, together with (i)
any manufacturer's warranties that Manager has received in connection with such
FF&E and (ii) a bill of sale or such other instrument of conveyance as is
reasonably necessary to accomplish said purchase; and GROUP shall simultaneously
convey to Manager the purchase price for said FF&E.  The purchase price shall be
paid all in cash, and shall equal the fair market value of the FF&E.

          2.2.    Manager shall be responsible for all repairs and maintenance
of the FF&E other than damage caused by negligence or willful misuse by GROUP;
provided, however, GROUP shall employ reasonable efforts to prevent damage to
and excessive wear of the FF&E, and shall promptly notify Manager of any needed
repairs thereto.

          2.3.    Manager shall be responsible for all property taxes and other
assessments relating to or arising out of ownership or use of the FF&E that
accrue on and after the date hereof.

          2.4.    Manager shall provide and maintain, at its expense, such
additional or replacement FF&E as the Practice reasonably requires from time to
time, as determined by Manager in its sole discretion, in consultation with

of Section 2.1 above.

          2.5.    GROUP may provide additional equipment at the Practice ("GROUP
Equipment") at its sole cost and expense.  GROUP shall be responsible for all
repairs, maintenance and replacement of, as well as all property taxes and other
assessments relating to or arising out of ownership or use of, such additional
equipment, unless GROUP requests that Manager provide such repairs, maintenance

Manager shall, in its sole and absolute discretion, determine the types and
numbers of personnel and the number of hours and schedules of said personnel it

required of Manager hereunder.

          3.6.    Subject to applicable securities, health care and other laws

shall not be liable to GROUP and shall not be deemed to be in default hereunder

such failure is a result of collective bargaining, a labor dispute, act(s) of
God, or any other event which is beyond the reasonable control of Manager or
which was not reasonably foreseeable by Manager.

     4.   RESPONSIBILITIES OF GROUP.

          4.1.    GROUP covenants and agrees that, at all times during the term

not limited to election of a Board of Directors, election of Officers,

Review and Quality Assurance Committees.  In addition, GROUP agrees to appoint a
Medical Director.  GROUP shall be solely responsible for payment of any and all
compensation, payroll taxes, fringe benefits, disability insurance, workers'
compensation insurance and any other benefits of all such individuals.

          4.2.    GROUP shall not enter into any agreements with Participating
Providers unless such Participating Providers have: (i) current unrestricted
licenses to practice their respective professions in the State of California and
(ii) current unrestricted Federal Drug Enforcement Agency ("DEA") numbers.  In
addition, where GROUP contracts with individual physicians, such physicians
shall have medical staff membership at the hospitals required by Participating
Plans and where GROUP contracts with licensed clinics and medical groups, at
least one primary care physician practicing at each clinic or medical group
shall have medical staff membership at the hospitals required by Participating
Plans.  GROUP further agrees to establish procedures to ensure that
Participating Providers meet these requirements on an ongoing basis.  Manager
shall reasonably cooperate with and assist GROUP to meet its obligations under
this Section 4.2; provided however, that GROUP acknowledges and agrees that it
shall retain ultimate responsibility for meeting such obligations.

          4.3.    GROUP acknowledges and agrees that it is solely responsible
for making all required reports to the Medical Board of California under Section

maintain at all times during the term of this Agreement comprehensive general
and professional liability insurance covering all activities of GROUP directly
or indirectly relating to GROUP, each policy in a


                                          12
<PAGE>

minimum amount of $1,000,000.00 per occurrence and $3,000,000.00 in the
aggregate.  The aforedescribed comprehensive general and professional liability
insurance shall be issued by a company or companies authorized to do business in
California with a financial rating of at least A:12 or better in "Best's Key
Rating Guide" or its equivalent.  In the event GROUP procures a "claims made"
policy as distinguished from an "occurrence" policy, GROUP shall procure and
maintain at its sole cost and expense, prior to termination of such insurance,
"tail" coverage to continue and extend coverage complying with this Agreement
after the end of the "claims made" policy.  Upon reasonable request from
Manager, GROUP shall cause to be issued to Manager proper certificates of
insurance, evidencing that the foregoing provisions of this Agreement have been
complied with, and said certificates shall provide that prior to any
cancellation or change in the underlying insurance during the policy period, the
insurance carrier shall first give thirty (30) calendar days written notice to
Manager.

          4.5.    Subject to the terms and conditions of Sections 3.1.6.3 and

$1,000,000.00 per occurrence and $3,000,000.00 in the aggregate.  GROUP shall

on a "claims made" rather than an "occurrences" form will obtain either extended
reporting insurance coverage ("tail coverage") with liability limits equal to
those most recently in effect prior to the day of termination of such
Participating Provider's contract with GROUP, or will enter into such other
arrangements as shall reasonably assure the maintenance of coverage for such
Provider, GROUP, and Manager against the risk of loss in respect of professional
services rendered by such provider while this Agreement was in effect and for a
period of not less than seven (7) years after the date of termination of this
Agreement.

          4.7.    GROUP acknowledges and agrees that it shall reasonably assist
and cooperate with Manager to meet all of Manager's obligations under this
Agreement, including approval of agreements and provision of information.  GROUP
acknowledges and agrees that Manager shall have no liability for GROUP's failure
to pay any and all of GROUP's debts and expenses.

Bylaws or any license, lease, franchise, mortgage, instrument, or other

reimbursed its Costs (as defined in Exhibit D attached hereto) and paid a
management fee (the "Management Fee") in the amount set forth on Exhibit D
attached hereto and incorporated herein by reference.

          9.2.    After deduction of amounts which are reimbursed by Manager and

on GROUP's behalf, the Cost of Medical Services (as defined in Exhibit D
attached hereto) such other payments or disbursement which Manager may be
authorized or required to make pursuant to this Agreement and such payments or
disbursements which GROUP shall direct Manager to make.  Should the funds in
GROUP's accounts not be sufficient at any time during the term of this Agreement
to make such disbursements and to meet the GROUP's financial obligations,
Manager shall have the right (but not the obligation) to loan to GROUP funds in
an amount sufficient to allow GROUP to meet its financial obligations.  Such
loan shall bear interest at a rate that is at or above fair market value and
shall have such other terms as the parties may agree from time to time.  Manager
shall not lend any funds to GROUP for such purposes without the prior approval
of GROUP's Board of Directors or the officer(s) of GROUP delegated such power of
approval by GROUP's Board of Directors.

     10.  RECORDS.

          10.1.   All medical records and documents, including reports, x-rays,
and other similar types of reports for patients of GROUP providers shall be the
property of GROUP's providers.  GROUP agrees to require GROUP providers to allow
Manager and its duly authorized representatives to inspect, audit and duplicate
any data or records necessary for Manager to perform its duties pursuant to this
Agreement.  GROUP and Manager shall comply with all applicable federal, state,
and local laws and regulations pertaining to the confidentiality of said medical
records.

          10.2.   All business records, information, software and systems of the
Manager relating to the provision of its services under this Agreement shall
remain the property of the Manager and may be removed by the Manager upon any
termination of this Agreement.

     11.  INDEMNIFICATION.  Each party shall indemnify, defend and hold harmless
the other, its officers, directors, agents, contractors, representatives and
employees, and each of its affiliates from and against any and all liability,
loss, damages, claims, causes of action, and expenses associated therewith
(including, without limitation, attorneys' fees) caused or asserted to have been
caused, directly or indirectly, by or as a result of any acts, errors or
omissions hereunder of the other, its contractors, shareholders, employees or
agents during the term hereof.  The provisions of this section shall survive the
expiration or earlier termination of this Agreement.

          12.1.   At all times during the term hereof and following the
expiration or earlier termination of this Agreement, all trade secrets and
proprietary confidential information of Manager, including without limitation,
all forms of contracts and other business documents or information of Manager,
whether currently or in the future developed or maintained by Manager and
including any and all deletions, additions, modifications and amendments thereto
and further including the amount of compensation to be paid to Manager for its
services hereunder  (collectively, "Manager's Proprietary Materials"), shall be
the exclusive, sole and absolute property of Manager.  Both parties acknowledge
and agree that Manager has developed Manager's Proprietary Materials at
significant expense, and that said Proprietary Materials are not available for
review or use by members of the public.  All of Manager's Proprietary Materials
are and shall at all times remain confidential and proprietary and constitute
valuable trade secrets of Manager.  Except in the ordinary course of performing
its obligations under this Agreement and except upon Manager's prior written
consent, GROUP shall not disclose to anyone, use, copy, or take any such trade
secrets or confidential and proprietary information for GROUP's benefit or gain
either during the term of this Agreement or at any time after the termination
hereof.  Upon any expiration or earlier termination of this Agreement for any
reason, GROUP shall not, without the prior written consent of Manager, take or
use any of Manager's Proprietary Materials, and shall return to Manager all of
Manager's Proprietary Materials in GROUP's possession or control.

          12.2.   At all times during the term hereof and following the
termination of this Agreement, GROUP shall not, directly or indirectly,
interfere with, disrupt or attempt to disrupt the relationship, contractual or
otherwise, between Manager and any health care provider or supplier (including,
without limitation, any physician or osteopath), or any employee, independent
contractor, consultant or agent of Manager.  GROUP further agrees not to hire,
engage or contract with, either as an independent contractor, employee or in any
other capacity, any personnel of Manager, other than personnel of Manager who
are GROUP's Former Employees, during the first twelve (12) months following the
effective expiration or termination date hereof without Manager's prior written
consent.

          12.3.   GROUP shall inform all of GROUP's Former Employees specified
by Manager in writing, within ten (10) days following the date hereof, that they
are now employees of Manager.  Notwithstanding the provisions of Section 12.2
above, upon termination of this Agreement, Manager may, at its option, require
GROUP upon written notice to hire any or all of GROUP's Former Employees at
salary and benefit levels equal to or greater than the salary and benefits that
Manager was paying those individuals as of their last day of employment with
Manager.

          12.4.   The provisions of this Section 12 shall survive the
termination of this Agreement.

     13.  INDEPENDENT CONTRACTORS.  The parties hereto acknowledge and agree
that the relationship created between Manager and GROUP is strictly that of

creating a partnership or joint venture


                                          19
<PAGE>

relationship between the parties.  Each party hereto shall be responsible for
all compensation, salaries, taxes, withholdings, contributions, benefits, and
workers' compensation insurance with respect to all personnel employed or
contracted by said party and shall indemnify, defend and hold harmless the other
party and its officers, directors, agents, contractors, representatives and
employees (and, in the case of GROUP's indemnification of Manager, Manager's
affiliates and subcontractors) from and against any and all liability, loss,
damages, claims, causes of action, and expenses associated therewith (including,
without limitation, attorneys' fees) caused or asserted to have been caused,
directly or indirectly, by or as a result of same.  The provisions of this
Section shall survive the expiration or earlier termination of this Agreement.

Assignable Option  Agreement in the form attached hereto as Exhibit E.

     15.  MISCELLANEOUS.

          15.1.   NO THIRD PARTY BENEFICIARIES.  The parties intend that the
benefits of this Agreement shall inure only to Manager and GROUP and not to any
third person, except as expressly so stated herein.  Notwithstanding anything
contained herein, or any conduct or course of conduct by any party hereto,
before or after signing this Agreement, this Agreement shall not be construed as
creating any right, claim or cause of action against either Manager or GROUP by
any other person or entity.

          15.2.   ENTIRE AGREEMENT.  This Agreement, together with all exhibits
and schedules hereto, and all documents referred to herein, constitutes the
entire agreement between the parties with respect to the subject matter hereof,
supersedes all other and prior agreements on the same subject, whether written
or oral, and contains all of the covenants and agreements between the parties
with respect to the subject matter hereof.  Each party to this Agreement
acknowledges that no representations, inducements, promises, or agreements,
orally or otherwise, have been made by the other party(ies), or by anyone acting
on behalf of any party, that are not embodied herein, and that no other
agreement, statement, or promise not contained in this Agreement shall be valid
or binding.  This Agreement incorporates the Original Management Services
Agreement, together with all amendments previously made and to be made to the
date of execution hereof, and is deemed to have been effective as of the date of
the Original Management Services Agreement.

          15.3.   SUCCESSORS AND ASSIGNS.  All of Manager's rights and duties
under this Agreement may be assigned or delegated by Manager, including but not

nor the rights and duties of this Agreement may be assigned or delegated by

the parties.

          15.4.   COUNTERPARTS.  This Agreement, and any amendments thereto, may
be executed in counterparts, each of which shall constitute an original
document, but which together shall constitute one and the same instrument.

          15.9.   SEVERABILITY.  If any provision of this Agreement is held by a
court of competent jurisdiction to be invalid or unenforceable, the remaining

invalidity or unenforceability would defeat an essential business purpose of
this Agreement.

          15.10.  EXHIBITS AND SCHEDULES.  All exhibits and schedules attached
to this Agreement are incorporated herein by this reference and all references
herein to "Agreement" shall mean this Agreement together with all such exhibits
and schedules.

          15.11.  TIME OF ESSENCE.  Time is expressly made of the essence of
this Agreement and each and every provision hereof of which time of performance
is a factor.

          15.12.  DISPUTE RESOLUTION.

                  15.12.1. Subject to the terms of Section 15.12.2, in the event
the parties hereto are unable to resolve any and all disputes in connection with
this Agreement, either party may commence arbitration by sending a written
demand for arbitration to the other party, setting


                                          21
<PAGE>

forth the nature of the matter to be resolved by arbitration.  Except as may be
expressly provided to the contrary herein, the arbitration procedure described
in this Section shall be the sole means of resolving any disputes hereunder.

                  15.12.2. Notwithstanding the foregoing, it is expressly
understood by the parties that the arbitration procedure described in this
Section shall not be applicable to any disputes between the parties as to
matters over which Manager has exclusive decision-making authority pursuant to
the terms hereof, including without limitation, the Manager's exclusive
decision-making authority with respect to the development of guidelines for the
selection, hiring and firing of health care professionals, compensation payable
to health care professionals, scope of services to be provided, patient
acceptance policies and procedures, pricing of services, negotiation and
execution of contracts, and approval of operating and capital budgets.

                  15.12.3. There shall be one arbitrator.  If the parties shall
fail to select a mutually acceptable arbitrator within ten (10) days after the
demand for arbitration is mailed, then the parties stipulate to arbitration
before a retired judge sitting on the Los Angeles Judicial Arbitration Mediation
Services (JAMS) panel.

                  15.12.4. The parties shall share all costs of arbitration.
The prevailing party shall be entitled to reimbursement by the other party of
such party's attorneys' fees and costs and any arbitration fees and expenses
incurred in connection with the arbitration hereunder.

                  15.12.5. The substantive law of the State of California shall
be applied by the arbitrator.  The parties shall have the rights of discovery as
provided for in Part 4 of the California Code of Civil Procedure and as provided
for in Section 1283.05 of said Code.  The California Code of Evidence shall
apply to testimony and documents submitted to the arbitrator.

                  15.12.6. Arbitration shall take place in Los Angeles,
California unless the parties otherwise agree.  As soon as reasonably
practicable, a hearing with respect to the dispute or matter to be resolved
shall be conducted by the arbitrator.  As soon as reasonably practicable
thereafter, the arbitrator shall arrive at a final decision, which shall be
reduced to writing, signed by the arbitrator and mailed to each of the parties
and their legal counsel.

                  15.12.7. All decisions of the arbitrator shall be final,
binding and conclusive on the parties and shall constitute the only method of
resolving disputes or matters subject to arbitration pursuant to this Agreement.
The arbitrator or a court of appropriate jurisdiction may issue a writ of
execution to enforce the arbitrator's judgment.  Judgment may be entered upon
such a decision in accordance with applicable law in any court having
jurisdiction thereof.

                  15.12.8. Notwithstanding the foregoing, because time is of the
essence of this Agreement, the parties specifically reserve the right to seek a
judicial temporary restraining order, preliminary injunction, or other similar
short term equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or
dissolve such court order.

                  15.12.9. Notwithstanding the foregoing, any and all
arbitration proceedings are conditional upon such proceedings being covered
under the parties' respective risk insurance policies.

          15.13.  ATTORNEYS' FEES.  Should either party institute any action or
procedure to enforce this Agreement or any provision hereof, or for damages by
reason of any alleged breach of this Agreement or of any provision hereof, or
for a declaration of rights hereunder (including, without limitation,
arbitration), the prevailing party in any such action or proceeding shall be
entitled to receive from the other party all costs and expenses, including
without limitation reasonable attorneys' fees, incurred by the prevailing party
in connection with such action or proceeding.

          15.14.  FURTHER ASSURANCES.  The parties shall take such actions and
execute and deliver such further documentation as may reasonably be required in
order to give effect to the transactions contemplated by this Management
Services Agreement and the intentions of the parties hereto.

          15.15.  RIGHTS CUMULATIVE.  The various rights and remedies herein
granted to Manager or GROUP shall be cumulative and in addition to any other
rights Manager or GROUP, respectively, may be entitled to under law.  The
exercise of one or more rights or remedies shall not impair the right of Manager
or GROUP to exercise any other right or remedy, at law or equity.

          15.16.  FEDERAL SOCIAL SECURITY REQUIREMENTS.  Pursuant to Section
1395x (V)(1)(I) of Title 42 of the United States Code, with respect to any
services furnished under the terms of this Agreement if the value or cost of
which is Ten Thousand Dollars ($10,000) or more over a twelve (12) month period,
until the expiration of four (4) years after the termination of this Agreement,
Manager shall make available upon written request to the Secretary of the United

costs of the services provided by Manager under this Agreement.

          Manager further agrees that in the event Manager carries out any of
its duties under this Agreement through a subcontract, with a value or cost of
Ten Thousand Dollars ($10,000) or more over a twelve (12) month period, such
subcontract shall contain a clause to the effect that until the expiration of
four (4) years after the furnishing of such services pursuant to such
subcontract, the subcontractor shall make available, upon written request to the
Secretary of the United States Department of Health and Human Services, or upon
request to the Comptroller General of the United States General Accounting
Office, or any of their duly authorized representatives, the subcontract and
such books, documents and records of such organization as are necessary to
verify the nature and extent of such costs.

          1.   FOR VALUE RECEIVED, PROSPECT MEDICAL SYSTEMS, INC., a Delaware
corporation ("MAKER"), promises to pay to the order of PROSPECT MEDICAL
HOLDINGS, INC., a Delaware corporation ("PAYEE"), on or before the Maturity Date
unless sooner accelerated in accordance with the terms hereof, the principal sum
of Three Million Dollars ($3,000,000).  As used herein the term "MATURITY DATE"
has the meaning given to such term in that certain Revolving Credit Agreement,
dated as of July 3, 1997, between Payee and Imperial Bank (as amended or
restated from time to time, the "CREDIT AGREEMENT").

          2.   This Secured Promissory Note shall bear interest at a per annum
rate equal to six percent (6%).  All computations of interest shall be
calculated on the basis of a year of three hundred sixty-five (365) days for the
actual days elapsed.  Interest shall accrue from the date of this Secured
Promissory Note to the date of repayment of this Secured Promissory Note in
accordance with the provisions hereof.  Maker shall pay all accrued but unpaid
interest on the principal balance hereof, in arrears, on the first day of each
and every month.

          3.   Maker shall make all payments hereunder in lawful money of the
United States of America and in immediately available funds to the holder hereof
("HOLDER") at Holder's office or to such other address as Holder may from time
to time specify by notice to Maker.

          4.   In no event shall the interest rate and other charges hereunder
exceed the highest rate permissible under any law which a court of competent
jurisdiction shall, in a final determination, deem applicable hereto.  In the
event that such a court determines that Holder has received interest and other
charges hereunder in excess of the highest rate applicable hereto, such excess
shall be deemed received on account of, and shall automatically be applied to
reduce, the principal balance hereof, and the provisions hereof shall be deemed
amended to provide for the highest permissible rate.  If there is no principal
balance outstanding, Holder shall refund to Maker such excess.

          5.   The unpaid principal balance hereof together with all accrued but
unpaid interest thereon shall be all due and payable upon (i) failure by Maker
to pay any installment of principal or interest due hereunder when due,
(ii) commencement of any proceeding by or against Maker under any bankruptcy or
insolvency laws, or (iii) the occurrence of an "Event of Default" under the
Credit Agreement.

          6.   This Secured Promissory Note is secured by that certain Security
Agreement, dated as of event date herewith, between Maker and Payee.

          7.   Maker hereby waives presentment for payment, notice of dishonor,
protest and notice of protest.

          8.   This Secured Promissory Note shall be governed by and construed
in accordance with the internal laws of the State of California without regard
to principles of conflicts of laws.

          IN WITNESS WHEREOF, Maker has duly executed this Secured Promissory
Note as of the date first above written.

references to the singular include the plural, the part includes the whole,
"including" is not limiting, and "or" has the inclusive meaning represented by

          3.   CREATION OF SECURITY INTEREST.  Debtor hereby grants to Secured
Party a continuing security interest in all presently existing and hereafter
acquired or arising Collateral in order to secure the prompt payment and

without further act on the part of Secured Party or Debtor.

               4.1  Debtor shall execute and deliver to Secured Party
concurrently with Debtor's execution of this Security Agreement, and from time
to time at the request of Secured Party, all financing statements, continuation
financing statements, fixture filings, security agreements, chattel mortgages,
assignments, and all other documents that Secured Party may request, in form
satisfactory to Secured Party, to perfect and maintain perfected Secured Party's
security interests in the Collateral and in order to consummate fully all of the
transactions contemplated by this Security Agreement and the Loan Agreement.
Debtor hereby irrevocably makes, constitutes, and appoints Secured Party (and
Secured Party's officers, employees, or agents) as Debtor's true and lawful
attorney with power to sign the


                                          6
<PAGE>

name of Debtor on any of the above-described documents or on any other similar
documents which need to be executed, recorded, or filed, and to do any and all
things necessary in the name and on behalf of Debtor in order to perfect, or
continue the perfection of, Secured Party's security interests in the
Collateral.  Debtor agrees that neither Secured Party, nor any of its designees
or attorneys-in-fact, will be liable for any act of commission or omission, or
for any error of judgment or mistake of fact or law with respect to the exercise
of the power of attorney granted under this Section 4.1, other than as a result
of its or their gross negligence or wilful misconduct.  THE POWER OF ATTORNEY
GRANTED UNDER THIS SECTION 4.1 IS COUPLED WITH AN INTEREST AND SHALL BE
IRREVOCABLE UNTIL ALL OF THE SECURED OBLIGATIONS HAVE BEEN INDEFEASIBLY PAID IN
FULL, THE LOAN AGREEMENT TERMINATED, AND ALL DEBTOR'S DUTIES HEREUNDER AND
THEREUNDER HAVE BEEN DISCHARGED IN FULL.

               4.2  Without limiting the generality of the foregoing Section 4.1
or any of the provisions of the Loan Agreement, Debtor will:  (i) at the request
of Secured Party, mark conspicuously all of its records pertaining to the
Collateral with a legend, in form and substance satisfactory to Secured Party,
indicating that the Collateral is subject to the security interest granted
hereby; (ii) at the request of Secured Party, appear in and defend any action or
proceeding which may affect Debtor's title to, or the security interest of
Secured Party in, any of the Collateral; and (iii) upon demand of Secured Party,
allow inspection of Collateral by Secured Party or Persons designated by Secured
Party at any time during normal business hours.

               4.3  With respect to the Negotiable Collateral (other than drafts
received in the ordinary course of business so long as no Event of Default is
continuing), Debtor shall, immediately upon request by Secured Party, endorse
(where appropriate) and assign the Negotiable Collateral over to Secured Party,
and deliver to Secured Party actual physical possession of the Negotiable
Collateral to Secured Party together with any instruments of transfer or
assignment, all in form and substance satisfactory to Secured Party, in order to
fully perfect the security interest therein of Secured Party.

               4.4  Debtor shall cooperate with Secured Party in obtaining a
control agreement in form and substance satisfactory to Secured Party with
respect to all Deposit Accounts and Investment Property.

          5.   EVENT OF DEFAULT.  Failure by Debtor to make any payment required
under the Note when due, whether for principal, interest, or otherwise, shall
constitute an Event of Default under this Security Agreement.

          6.   RIGHTS AND REMEDIES.

               6.1  During the continuance of an Event of Default, Secured
Party, without notice or demand, may do any one or more of the following, all of
which are authorized by Debtor:


                                          7
<PAGE>

                    (a)  Settle or adjust disputes and claims directly with
Account Debtors for amounts and upon terms which Secured Party considers
advisable, and in such cases, Secured Party will credit the Secured Obligations
with only the net amounts received by Secured Party in payment of such disputed
Accounts after deducting all Secured Party Expenses incurred or expended in
connection therewith;

                    (b)  Cause Debtor to hold all returned Inventory in trust
for Secured Party, segregate all returned Inventory from all other property of
Debtor or in Debtor's possession and conspicuously label said returned Inventory
as the property of Secured Party;

                    (c)  Without notice to or demand upon Debtor or any
guarantor, make such payments and do such acts as Secured Party considers
necessary or reasonable to protect its security interests in the Collateral.
Debtor agrees to assemble the Collateral if Secured Party so requires, and to
make the Collateral available to Secured Party as Secured Party may designate.
Debtor authorizes Secured Party to enter the premises where the Collateral is
located, to take and maintain possession of the Collateral, or any part of it,
and to pay, purchase, contest, or compromise any encumbrance, charge, or Lien
that in Secured Party's determination appears to conflict with its security
interests and to pay all expenses incurred in connection therewith.  With
respect to any of Debtor's owned or leased premises, Debtor hereby grants
Secured Party a license to enter into possession of such premises and to occupy
the same, without charge, for up to 120 days in order to exercise any of Secured
Party's rights or remedies provided herein, at law, in equity, or otherwise;

                    (d)  Without notice to Debtor (such notice being expressly
waived), and without constituting a retention of any collateral in satisfaction
of an obligation (within the meaning of Section 9505 of the Code), set off and
apply to the Secured Obligations any and all (i) balances and Deposit Accounts
of Debtor held by Secured Party, or (ii) indebtedness at any time owing to or
for the credit or the account of Debtor held by Secured Party;

                    (e)  Hold, as cash collateral, any and all balances and
Deposit Accounts of Debtor held by Secured Party, to secure the full and final
repayment of all of the Secured Obligations;

                    (f)  Ship, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner provided
for herein) the Collateral.  Secured Party is hereby granted a license or other
right to use, without charge, Debtor's labels, patents, copyrights, rights of
use of any name, trade secrets, trade names, trademarks, service marks, and
advertising matter, or any property of a similar nature, as it pertains to the
Collateral, in completing production of, advertising for sale, and selling any
Collateral and Debtor's rights under all licenses and all franchise agreements
shall inure to Secured Party's benefit;


                                          8
<PAGE>

                    (g)  Sell the Collateral at either a public or private sale,
or both, by way of one or more contracts or transactions, for cash or on terms,
in such manner and at such places (including Debtor's premises) as Secured Party
determines is commercially reasonable.  It is not necessary that the Collateral
be present at any such sale;

                    (h)  Secured Party shall give notice of the disposition of
the Collateral as follows:

                         (i)  Secured Party shall give Debtor and each holder of
a security interest in the Collateral who has filed with Secured Party a written
request for notice, a notice in writing of the time and place of public sale,
or, if the sale is a private sale or some other disposition other than a public
sale is to be made of the Collateral, then the time on or after which the
private sale or other disposition is to be made;

                        (ii)  The notice shall be personally delivered or
mailed, postage prepaid, to Debtor as provided in SECTION 9 of this Security
Agreement, at least 5 days before the date fixed for the sale, or at least 5
days before the date on or after which the private sale or other disposition is
to be made; no notice needs to be given prior to the disposition of any portion
of the Collateral that is perishable or threatens to decline speedily in value
or that is of a type customarily sold on a recognized market.  Notice to Persons
other than Debtor claiming an interest in the Collateral shall be sent to such
addresses as they have furnished to Secured Party;

                       (iii)  If the sale is to be a public sale, Secured Party
also shall give notice of the time and place by publishing a notice one time at
least 5 days before the date of the sale in a newspaper of general circulation
in the county in which the sale is to be held;

                    (i)  Secured Party may credit bid and purchase at any public
sale; and

                    (j)  Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Debtor.  Any excess
will be returned, without interest and subject to the rights of third Persons,
by Secured Party to Debtor.

               6.2  Upon the exercise by Secured Party of any power, right,
privilege, or remedy pursuant to this Security Agreement which requires any
consent, approval, registration, qualification, or authorization of any
Governmental Authority, Debtor agrees to execute and deliver, or will cause the
execution and delivery of, all applications, certificates, instruments,
assignments, and other documents and papers that Secured Party or any purchaser
of the Collateral may be required to obtain for such governmental consent,
approval, registration, qualification, or authorization.

               6.3  The rights and remedies of Secured Party under this Security
Agreement, the Loan Agreement, the other Loan Documents, and all other
agreements


                                          9
<PAGE>

contemplated hereby and thereby shall be cumulative.  Secured Party shall have
all other rights and remedies not inconsistent herewith as provided under the
Code, by law, or in equity.  No exercise by Secured Party of any one right or
remedy shall be deemed an election of remedies, and no waiver by Secured Party
of any default on Debtor's part shall be deemed a continuing waiver of any
further defaults.  No delay by Secured Party shall constitute a waiver, election
or acquiescence with respect to any right or remedy.

          7.   SECURED PARTY NOT LIABLE.  So long as Secured Party complies with
the obligations, if any, imposed by Section 9207 of the Code, Secured Party
shall not otherwise be liable or responsible in any way or manner for:  (a) the
safekeeping of the Collateral; (b) any loss or damage thereto occurring or
arising in any manner or fashion or from any cause; (c) any diminution in the
value thereof; or (d) any act or default of any carrier, warehouseman, bailee,
forwarding agency, or other person whomsoever.

          8.   INDEFEASIBLE PAYMENT.  The Secured Obligations shall not be
considered indefeasibly paid for purposes of this Security Agreement unless and
until all payments to Secured Party are no longer subject to any right on the
part of any Person, including Debtor, Debtor as a debtor in possession, or any
trustee (whether appointed under the Bankruptcy Code or otherwise) of Debtor or
Debtor's Assets to invalidate or set aside such payments or to seek to recoup
the amount of such payments or any portion thereof, or to declare same to be
fraudulent or preferential.  In the event that, for any reason, any portion of
such payments to Secured Party is set aside or restored, whether voluntarily or
involuntarily, after the making thereof, then the obligation intended to be
satisfied thereby shall be revived and continued in full force and effect as if
said payment or payments had not been made.

          9.   NOTICES.  All notices, requests and other communications to any
party hereunder shall be in writing (including facsimile transmission or similar
writing) and shall be given to such party at its address or facsimile number set
forth on the signature pages hereof or such other address or facsimile number as
such party may hereafter specify by notice to the other party in accordance with
this Section 9.  Each such notice, request or other communication shall be
deemed given on the second business day after mailing; PROVIDED that actual
notice, however and from whomever given or received, shall always be effective
on receipt; PROVIDED FURTHER that notices sent by Secured Party in connection
with Sections 9504 or 9505 of the California Uniform Commercial Code shall be
deemed given when deposited in the mail or personally delivered, or, where
permitted by law, transmitted by facsimile.

          10.  GENERAL PROVISIONS.

               10.1 SUCCESSORS AND ASSIGNS.  This Security Agreement shall bind
and inure to the benefit of the respective successors and assigns of Debtor and
Secured Party; PROVIDED, HOWEVER, that Debtor may not assign this Security
Agreement nor delegate any of its duties hereunder without Secured Party's prior
written consent and any prohibited assignment or delegation shall be absolutely
void.  No consent by Secured Party to an assignment by Debtor shall release
Debtor from the Secured Obligations.  Secured Party


                                          10

from time to time to Imperial Bank or its assigns without prior notice to, or
the consent of Debtor and Debtor agrees to recognize such lender as Secured
Party's assignee under this Security Agreement.

               10.2 EXHIBITS AND SCHEDULES.  All of the exhibits and schedules
attached hereto shall be deemed incorporated by reference.

               10.3 NO PRESUMPTION AGAINST ANY PARTY.  Neither this Security
Agreement nor any uncertainty or ambiguity herein shall be construed or resolved
against Secured Party or Debtor, whether under any rule of construction or
otherwise.  On the contrary, this Security Agreement has been reviewed by each
of the parties and their counsel and shall be construed and interpreted
according to the ordinary meaning of the words used so as to accomplish fairly
the purposes and intentions of all parties hereto.

               10.4 AMENDMENTS AND WAIVERS.  Any provision of this Agreement may
be amended or waived if, but only if, such amendment or waiver is in writing and
is signed by the party asserted to be bound thereby, and then such amendment or
waiver shall be effective only in the specific instance and specific purpose for
which given.

               10.5 COUNTERPARTS; INTEGRATION; EFFECTIVENESS.  This Security
Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument.  This Security Agreement constitutes the entire agreement
and understanding among the parties hereto and supersedes any and all prior
agreements and understandings, oral or written, relating to the subject matter
hereof.  This Security Agreement shall become effective when executed by each of
the parties hereto and delivered to Secured Party.

               10.6 SEVERABILITY.  The provisions of this Agreement are
severable.  The invalidity, in whole or in part, of any provision of this
Agreement shall not affect the validity or enforceability of any other of its
provisions.  If one or more provisions hereof shall be declared invalid or
unenforceable, the remaining provisions shall remain in full force and effect
and shall be construed in the broadest possible manner to effectuate the
purposes hereof.

          11.  GOVERNING LAW.  This Security Agreement shall be deemed to have
been made in the State of California and the validity, construction,
interpretation, and enforcement hereof, and the rights of the parties hereto,
shall be determined under, governed by, and construed in accordance with the
internal laws of the State of California, without regard to principles of
conflicts of law.

          12.  SUBORDINATION OF SECURITY INTEREST.  Secured Party hereby
expressly agrees that the security interests granted to it under this Security

inferior to any and all liens, rights, powers, titles and interests of Imperial
Bank or its assigns in the Collateral ("SENIOR LIENS") granted by Debtor
pursuant to that certain Security Agreement, dated as of July 3, 1997, between
Debtor and Imperial Bank, and Secured Party agrees that all Senior Liens shall

shall be and remain expressly subject and subordinate to any renewal, extension,
refinancing, consolidation, modification or supplement of the liens, rights,
titles and interests of the Senior Liens, as well as any and all increases
thereof.

          14.  JUDICIAL REFERENCE.

               14.1 REFERENCE PROCEEDING.  Other than (i) nonjudicial
foreclosure and all matters in connection therewith regarding security interests
in real or personal property; or (ii) the appointment of a receiver, or the
exercise of other provisional remedies (any and all of which may be initiated
pursuant to applicable law), each controversy, dispute or claim between the
parties arising out of or relating to this Assignment, which 


                                          4
<PAGE>

controversy, dispute or claim is not settled in writing within thirty (30) days
after the "CLAIM DATE" (defined as the date on which either Assignor or Bank
gives written notice to the other that a controversy, dispute or claim exists),
will be settled by a reference proceeding in California in accordance with the
provisions of Section 638 ET SEQ. of the California Code of Civil Procedure, or
their successor section ("CCP"), which shall constitute the exclusive remedy for
the settlement of any controversy, dispute or claim concerning this Assignment,
including whether such controversy, dispute or claim is subject to the reference
proceeding and except as set forth above, the parties waive their rights to
initiate any legal proceedings against each other in any court or jurisdiction
other than the Superior Court in Los Angeles County (the "COURT").  The referee
shall be a retired Judge of the Court selected by mutual agreement of the
parties, and if they cannot so agree within forty-five (45) days after the Claim
Date, the referee shall be promptly selected by the Presiding Judge of the Court
(or his representative).  The referee shall be appointed to sit as a temporary
judge, with all of the powers for a temporary judge, as authorized by law, and
upon selection should take and subscribe to the oath of office as provided for
in Rule 244 of the California Rules of Court (or any subsequently enacted Rule).
Each party shall have one peremptory challenge pursuant to CCP Section 170.6. 
The referee shall (a) be requested to set the matter for hearing within sixty
(60) days after the date of selection of the referee and (b) try any and all
issues of law or fact and report a statement of decision upon them, if possible,
within ninety (90) days of the Claim Date.  Any decision rendered by the referee
will be final, binding and conclusive and judgment shall be entered pursuant to
CCP Section 644 in any court in the State of California having jurisdiction. 
Any party may apply for a reference proceeding at any time after thirty (30)
days following notice to any other party of the nature of the controversy,
dispute or claim, by filing a petition for a hearing and/or trial.  All
discovery permitted by this Assignment shall be completed no later than fifteen
(15) days before the first hearing date established by the referee.  The referee
may extend such period in the event of a party's refusal to provide requested
discovery for any reason whatsoever, including, without limitation, legal
objections raised to such discovery or unavailability of a witness due to
absence or illness.  No party shall be entitled to "priority" in conducting
discovery.  Depositions may be taken by either party upon seven (7) days written
notice, and request for production or inspection of documents shall be responded
to within ten (10) days after service.  All disputes relating to discovery which
cannot be resolved by the parties shall be submitted to the referee whose
decision shall be final and binding upon the parties.  Pending appointment of
the referee as provided herein, the Court is empowered to issue temporary and/or
provisional remedies, as appropriate.

               14.2 MANNER OF REFERENCE PROCEEDING.  Except as expressly set
forth in this Assignment, the referee shall determine the manner in which the
reference proceeding is conducted including the time and place of all hearings,
the order of presentation of evidence, and all other questions that arise with
respect to the course of the reference proceeding.  All proceedings and hearings
conducted before the referee, except for trial, shall be conducted without a
court reporter except that when any party so requests, a court reporter will be
used at any hearing conducted before the referee.  The party making such a
request shall have the obligation to arrange for and pay for the court reporter.
The costs 


                                          5
<PAGE>

of the court reporter at the trial shall be borne equally by the parties.

               14.3 DUTIES OF REFEREE.  The referee shall be required to
determine all issues in accordance with existing case law and the statutory laws
of the State of California.  The rules of evidence applicable to proceedings at
law in the State of California will be applicable to the reference proceeding. 
The referee shall be empowered to enter equitable as well as legal relief, to
provide all temporary and/or provisional remedies and to enter equitable orders
that will be binding upon the parties.  The referee shall issue a single
judgment at the close of the reference proceeding which shall dispose of all of
the claims of the parties that are the subject of the reference.  The parties
hereto expressly reserve the right to contest or appeal from the final judgment
or any appealable order or appealable judgment entered by the referee.  The
parties hereto expressly reserve the right to findings of fact, conclusions of
laws, a written statement of decision, and the right to move for a new trial or
a different judgment, which new trial, if granted, is also to be a reference
proceeding under this provision.

               14.4 ARBITRATION ALTERNATIVE.  In the event that the enabling
legislation which provides for appointment of a referee is repealed (and no
successor statute is enacted), any dispute between the parties that would
otherwise be determined by the reference procedure herein described will be
resolved and determined by arbitration.  The arbitration will be conducted by a
retired judge of the Court, in accordance with the California Arbitration Act,
Section 1280 through Section 1294.2 of the CCP as amended from time to time. 
The limitations with respect to discovery as set forth hereinabove shall apply
to any 


                                          6

such arbitration proceeding.

     EXECUTED as of the date first above written.

following, all of which are authorized by Physician Group:

                    (a)  Make such payments and do such acts as it considers
necessary or reasonable to protect Manager's security interest in the
Collateral.  Physician Group agrees to assemble and make available any or all of
the Collateral if Manager so requires.  Physician Group authorizes Manager to
enter the premises where the Collateral is located, take and maintain possession
of the Collateral, or any part of it, and to pay, purchase, contest, or
compromise any encumbrance, charge, or lien which, in the opinion of the
Manager, appears to be prior or superior to Manager's security interest, and to
pay all costs and expenses incurred in connection therewith;

                    (b)  Sell the Collateral, at either a public or private
sale, or both, by way of one or more contracts or transactions, for cash or on
terms, in such manner and at such places (including Physician Group's premises)
as is commercially reasonable, and apply any proceeds of any sale or other
disposition of the Collateral in the order provided in Section 9504 of the Code,
including the payment of Expenses.  It is not necessary that the Collateral be
present at any such sale;

                    (c)  Without constituting a retention of collateral in
satisfaction of indebtedness as provided for in Section 9505 of the Code, notify
account debtors and other obligors of Physician Group of Manager's security
interests in the Collateral, and proceed to collect the same and apply the net
cash proceeds therefrom to the Secured Obligations;

                    (d)  Manager shall give notice of any disposition of the
Collateral as follows:

                         (i)   Manager shall give Physician Group and each
holder of a security interest in the Collateral who has filed with Manager a
written request for notice, a written notice stating the time and place of a
public sale, or, if the disposition


                                          6
<PAGE>

is to be either a private sale or some other disposition that is not a public
sale, the time on or after which the private sale or other disposition is to be
made;

                         (ii)  The notice described in the immediately
preceding paragraph shall be delivered to Physician Group as provided in Section
8.3 of the Management Agreement at least five (5) calendar days before the date
fixed for a sale.  Notice to persons other than Physician Group claiming an
interest in the Collateral shall be sent to such addresses as such persons have
furnished to Manager prior to the date of such notice;

                         (iii) If the disposition is to be a public sale,
Manager shall also give notice of the time and place of said sale by publishing
a notice at least five (5) calendar days before the date of the sale in a
newspaper of general circulation, if one exists, in the county in which the sale
is to be held;

                    (e)  Manager may, in its own name, or in the name of a
designee or nominee, credit bid and purchase at any public sale;

                    (f)  Physician Group shall pay all Expenses; and

                    (g)  Any portion of the Secured Obligations which remains
unpaid after disposition of the Collateral as provided above shall be paid
immediately by Physician Group.  Any excess which exists after disposition of
the Collateral and payment in full of the Secured Obligations shall be returned
promptly, without interest and subject to the rights of third persons, to
Physician Group by Manager.

               8.2  FURTHER DOCUMENTATION.  Upon the exercise by Manager of any
power, right, privilege, or remedy pursuant to this Security Agreement which
requires any consent, approval, registration, qualification, or authorization of
any Governmental Authority, Physician Group agrees to execute and deliver, or
will cause the execution and delivery of, all applications, certificates,
instruments, assignments, and other documents and papers that Manager or any
purchaser of the Collateral may be required to obtain for such governmental
consent, approval, registration, qualification, or authorization.

               8.3  CUMULATIVE REMEDIES; WAIVERS.  The rights and remedies of
Manager under this Security Agreement, the Management Agreement, and all other
agreements contemplated hereby and thereby shall be cumulative.  Manager shall
have all other rights and remedies not inconsistent herewith as provided under
the Code, by law, or in equity.  No exercise by Manager of any one right or
remedy shall be deemed an election of remedies, and no waiver by Manager of any
default on Physician Group's part shall be deemed a continuing waiver of any
further defaults.  No delay by Manager shall constitute a waiver, election or
acquiescence with respect to any right or remedy.

          12.  NO VIOLATION OF APPLICABLE LAW.  To the extent that any lien or
security interest on any Asset(s) granted by Physician Group herein violates any
applicable Health Care Law, the grant of such lien or security interest on such
Asset(s) shall be automatically null and void; provided however, that to the
extent such lien or security interest at any time hereafter no longer violates

interests on other Asset(s) granted by Physician Group herein that do not
violate any applicable Health Care Law shall remain at all times in full force

and severally, shall indemnify and defend Bank against any and all claims,
expenses, liabilities and losses, including reasonable attorneys' fees, incurred

          (b)  SURVIVAL.  The obligations of the parties under this Section 10

     11.  FURTHER AGREEMENTS.

          (a)  PARTY TO AGREEMENT.  The PC Shareholders, or their estate, as the
case may be, Holdings, the Management Companies and each of the Professional
Corporations hereby agree that they shall cause any New Shareholder and any
Successor Shareholder to become a party to this Agreement upon and as a
condition to becoming a New Shareholder or a Successor Shareholder and agree
that each such New Shareholder or Successor Shareholder shall be, and the PC
Shareholders, and each of the Professional Corporations shall cause them to be,
bound by the terms hereof with the same obligations and liabilities as the PC
Shareholders.  The parties hereto agree that any shares of any of the
Professional Corporations acquired by any party hereto, any New Shareholder, any
Successor Shareholder shall be or become Shares hereunder and the PC
Shareholders, the Management Companies, Holdings and the Professional
Corporations shall cause such Shares to be delivered to Bank in accordance with
the terms hereof.

          (b)  TRANSFER OF SHARES.  During the term of this Agreement no New

respect to the subject matter hereof.  Upon the occurrence of a Succession
Event, in the case of any conflict or inconsistency between this Agreement and
any Option Agreement, this Agreement shall control.

     14.  SPECIFIC PERFORMANCE.  The PC Shareholders and the Professional
Corporations agree that a breach of any covenants contained in this Agreement
will cause irreparable injury to Bank, that Bank has no adequate remedy at law

covenant contained in this Agreement shall be specifically enforceable against
each of them, and each hereby waives and agrees not to assert any defenses
against an action for specific performance of such covenants.

     15.  NOTICES.  All notices, requests, demands and other communications

     16.  ATTORNEYS' FEES.  Should any parties hereto institute any action or
proceeding at law, in equity or in arbitration to enforce any provision of this
Agreement, including an action for declaratory relief or for damages by reason
of an alleged breach of any provision of this Agreement or otherwise in

shall be entitled to recover from the losing party such prevailing party's
reasonable attorneys' fees and costs in such action or proceeding.

     17.  MISCELLANEOUS.

          (a)  ENTIRE AGREEMENT.  This Agreement and the other Loan Documents
constitute the entire understanding and agreement of the parties with respect to
the subject matter hereof and any and all prior agreements, understandings or
representations with respect to such subject matter are hereby terminated and
canceled in their entirety and are of no further force or effect.

          (b)  SEVERABILITY.  Nothing contained herein shall be construed so as
to require the commission of any act contrary to law, and whenever there is any
conflict between any provision contained herein and any present or future
constitution, statute, law, ordinance, rule or regulation, the latter shall
prevail; PROVIDED, HOWEVER, that the provision of this Agreement which is
affected shall be curtailed and limited only to the extent necessary to bring it
within the requirements of the law.  In any event, all other provisions of this
Agreement shall be deemed valid and enforceable to the fullest extent possible.

          (c)  FURTHER ASSURANCES.  Each of the parties hereto shall execute and
deliver any and all additional papers, documents, and other assurances, and
shall do any and all acts and things reasonably necessary in connection with the
performance of its obligations hereunder to carry out the intent of the parties
hereto.

          (d)  MODIFICATIONS OR AMENDMENTS.  No amendment, change or
modification of this Agreement shall be valid, unless in writing and signed by
all of the parties hereto.

          (e)  NO WAIVER; AMENDMENTS.  No failure on the part of Bank to
exercise, no delay in exercising and no course of dealing with respect to, any
right hereunder shall operate as a waiver thereof; nor shall any single or
partial exercise of any right hereunder or under any of the other Loan Documents
preclude any other or further exercise thereof or the exercise of any other
right.  The remedies herein provided are cumulative and not exclusive of any
remedies provided by law.

                                          8

          (f)  JOINT AND SEVERAL LIABILITY.  The PC Shareholders, Holdings, the
Management Companies and the Professional Corporations each agree that the
liability hereunder shall be the immediate, direct, and primary obligation of
such Person and shall not be contingent upon Bank's exercise or enforcement of
any remedy it may have against any of them or against any other Person, or
against the Collateral or any other security for the Obligations or the Guaranty
Obligations.  Without limiting the generality of the foregoing, this Agreement
shall remain in full force and effect without regard to and shall not be

               (viii) Bank's vote, claim, distribution, election, acceptance,
action or inaction in any bankruptcy case related to the Obligations, the

          (k)  ASSIGNMENT.  This Agreement may not be assigned by any PC

                                          10
<PAGE>


GOVERNED BY, CONSTRUED AND INTERPRETED IN ACCORDANCE WITH THE INTERNAL LAWS OF
THE STATE OF CALIFORNIA WITHOUT GIVING EFFECT TO ANY PRINCIPLES OF CONFLICT OF
LAWS.

          (m)  AMENDED AND RESTATED AGREEMENT.  This Agreement shall amend and
restate in its entirety, supersede, and continue the obligations incurred under,
the Prior Agreement.

          (n)  JUDICIAL REFERENCE.  Other than (i) nonjudicial foreclosure and
all matters in connection therewith regarding security interests in real or
personal property; or (ii) the appointment of a receiver, or the exercise of
other provisional remedies (any and all of which may be initiated pursuant to
applicable law), each controversy, dispute or claim between the parties arising
out of or relating to this Agreement, which controversy, dispute or claim is not
settled in writing within thirty (30) days after the "CLAIM DATE" (defined as
the date on which a party subject to the Agreement gives written notice to all
other parties that a controversy, dispute or claim exists), will be settled by a
reference proceeding in California in accordance with the provisions of Section
638 ET SEQ. of the California Code of Civil Procedure, or their successor
section ("CCP"), which shall constitute the exclusive remedy for the settlement
of any controversy, dispute or claim concerning this Agreement, including
whether such controversy, dispute or claim is subject to the reference
proceeding and except as set forth above, the parties waive their rights to
initiate any legal proceedings against each other in any court or jurisdiction
other than the Superior Court in the County where the Real Property, if any, is
located or Los Angeles County if none (the "Court").  The referee shall be a
retired Judge of the Court selected by mutual agreement of the parties, and if
they cannot so agree within forty-five (45) days after the Claim Date, the
referee shall be promptly selected by the Presiding Judge of the Court (or his
representative).  The referee shall be appointed to sit as a temporary judge,
with all of the powers for a temporary judge, as authorized by law, and upon
selection should take and subscribe to the oath of office as provided for in
Rule 244 of the California Rules of Court (or any subsequently enacted Rule). 
Each party shall have one peremptory challenge pursuant to CCP Section 170.6. 
The referee shall (a) be requested to set the matter for hearing within sixty
(60) days after the Claim Date and (b) try any and all issues of law or fact and
report a statement of decision upon them, if possible, within ninety (90) days
of the Claim Date.  Any decision rendered by the referee will be final, binding
and conclusive and judgment shall be entered pursuant to CCP Section 644 in any
court in the State of California having jurisdiction.  Any party may apply for a
reference proceeding at any time after thirty (30) days following notice to any
other party of the nature of the controversy, dispute or claim, by filing a
petition for a hearing and/or trial.  All discovery permitted by this Agreement
shall be completed no later than fifteen (15) days before the first hearing date
established by the referee.  The referee may extend such period in the event of
a party's refusal to provide requested discovery for any reason whatsoever,
including, without limitation, legal objections raised to such discovery or
unavailability of a witness due to absence or illness.  No party shall be
entitled to "priority" in conducting discovery.  Depositions may be taken by
either party upon seven (7) days written notice, and request for production or
inspection of documents shall be responded to within ten (10) days after 

                                          11
<PAGE>

service.  All disputes relating to discovery which cannot be resolved by the
parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Superior Court is empowered to issue temporary and/or provisional
remedies, as appropriate.

          Except as expressly set forth in this Agreement, the referee shall
determine the manner in which the reference proceeding is conducted including
the time and place of all hearings, the order of presentation of evidence, and
all other questions that arise with respect to the course of the reference
proceeding.  All proceedings and hearings conducted before the referee, except
for trial, shall be conducted without a court reporter except that when any
party so requests, a court reporter will be used at any hearing conducted before
the referee.  The party making such a request shall have the obligation to
arrange for and pay for the court reporter.  The costs of the court reporter at
the trial shall be borne equally by the parties.

          The referee shall be required to determine all issues in accordance
with existing case law and the statutory laws of the State of California.  The
rules of evidence applicable to proceedings at law in the State of California
will be applicable to the reference proceeding.  The referee shall be empowered
to enter equitable as well as legal relief, to provide all temporary and/or
provisional remedies and to enter equitable orders that will be binding upon the
parties.  The referee shall issue a single judgment at the close of the
reference proceeding which shall dispose of all of the claims of the parties
that are the subject of the reference.  The parties hereto expressly reserve the
right to contest or appeal from the final judgment or any appealable order or
appealable judgment entered by the referee.  The parties hereto expressly
reserve the right to findings of fact, conclusions of laws, a written statement
of decision, and the right to move for a new trial or a different judgment,
which new trial, if granted, is also to be a reference proceeding under this
provision.

          In the event that the enabling legislation which provides for
appointment of a referee is repealed (and no successor statute is enacted), any
dispute between the parties that would otherwise be determined by the reference
procedure herein described will be resolved and determined by arbitration.  The
arbitration will be conducted by a retired judge of the Court, in accordance
with the California Arbitration Act, Section 1280 through Section 1294.2 of the
CCP as amended from time to time.  The limitations with respect to discovery as
set forth hereinabove shall apply to any such arbitration proceeding.

     1.3  Group and Prospect Medical Group represent and warrant that as of the
day and year first above written and during the term of this Agreement, Exhibits
A and B are true and complete listings of the Assets and Stock, respectively, as
revised from time to time pursuant to this Agreement.

     1.4  Other than in connection with that certain Amended and Restated Credit
Succession Agreement, dated as of July 14, 1997, by and among Prospect Medical
Holdings, Inc., a Delaware corporation ("Prospect Medical Holdings"), Prospect
Medical Group, Gregg DeNicola, M.D., Santa Ana/Tustin Physicians Group, Inc., a
California professional corporation ("Santa Ana"), Prospect Medical Systems,
Inc., a Delaware corporation ("Prospect Medical Systems"), and Imperial Bank, a
California banking corporation ("Imperial"), as amended, and as supplemented by

Sierra Medical Management, Group, Gregg DeNicola, M.D., Prospect Medical
Holdings, Prospect Medical Systems, Prospect Medical Group, Santa Ana and
Imperial (as amended and supplemented, the "Amended and Restated Credit
Succession Agreement"), Group shall not recognize any share transfer or other
action not in compliance with the terms of this Agreement.

2.   TERM OF AGREEMENT.  The term of this Agreement commences as of the day and
year first above written and continues for thirty (30) years ("Term").  So long
as the term of the Management Services Agreement, made and entered into of even
date herewith, by and between Sierra Medical Management and Group, as amended
(the "Management Services Agreement"), is automatically extended pursuant
thereto, the term of this Agreement shall be automatically extended for
additional coextensive terms of ten (10) years each.  In the event the
Management Services Agreement is terminated pursuant to its terms, this
Agreement shall terminate upon the effective date of termination of said
Management Services Agreement.

3.   OPTION PRICE.  The purchase price for the Option (the "Option Price") is

receipt of such payment.

                                       2

<PAGE>

4.   EXERCISE OF OPTION.

     4.1  During the Term of the this Agreement, Sierra Medical Management may
elect to exercise the Option at any time.  In the event of an election by Sierra
Medical Management to exercise the Option, Sierra Medical Management may
exercise either the Assets Option or the Stock Option, or both, at Sierra
Medical Management's sole discretion.

     4.2  Notwithstanding the provisions of Section 4.1, if the Management
Services Agreement is terminated by either party, for any reason, Sierra Medical
Management's right to exercise the Option  is automatically and immediately
exercised as of the termination date of the Management Services Agreement such
that Sierra Medical Management may exercise either the Assets Option or the
Stock Option, or both, at  such time.

     4.3  To the extent that the Assets Option is exercised by Sierra Medical
Management, Sierra Medical Management will send Group a written notice (the
"Assets Exercise Notice") specifying the Assets to be purchased.   Sierra
Medical Management may exercise the Assets Option as many times as Sierra
Medical Management elects in its sole discretion.

     4.4  To the extent that the Stock Option is exercised by Sierra Medical
Management, Sierra Medical Management will send Group a written notice (the
"Stock Exercise Notice") specifying the Stock to be purchased.   Sierra Medical
Management may designate the Successor Physician(s) who will exercise the Stock
Option as many times as Sierra Medical Management elects in its sole discretion.

     4.5  The Assets Option and the Stock Option are independent of each other,
and can be exercised at different times during the Term.

     4.6  Sierra Medical Management may cancel any Assets Exercise Notice or
Stock Exercise Notice at any time.

     4.7  Group and Prospect Medical Group shall cooperate with Sierra Medical
Management in any due diligence.

5.   ASSIGNMENT OF THE OPTION.  Sierra Medical Management may elect to assign
either the Assets Option or the Stock Option or both to any person, by a written
assignment, signed by both Sierra Medical Management and the assignee, which
designates the Assets or Stock.  The assignee shall agree as a condition of the
assignment to be bound by the terms of this Agreement.   Thereafter, only the
assignee named in the assignment (or its nominee) shall have the right to
exercise the applicable Assets Option and/or the Stock Option as to the
designated Assets and/or Stock, and that assignee, rather than Sierra Medical
Management, shall enter into a purchase agreement upon exercise of the Assets
Option and/or the Stock Option, as applicable.  Written notice of any such
assignment shall be given by Sierra Medical Management to Group and 

                                       3

<PAGE>

Prospect Medical Group within a reasonable time period following execution of 
any assignment pursuant to this Agreement.  When the context so requires in 
this Agreement, the term "Sierra Medical Management" shall be deemed to refer 
to an assignee holding an assignment of an Asset Option or Stock Option, and 
the terms "party" and "parties" shall be deemed to include that assignee.  
The parties further understand and agree that the Assets Option and the Stock 
Option are concurrently herewith being collaterally assigned to Imperial 
pursuant to that certain Collateral Assignment of Transaction Documents, 
dated as of September 25, 1997.

6.   PURCHASE PRICE OF THE ASSETS OR STOCK.

     6.1  PURCHASE PRICE.

          (a)  ASSETS PURCHASE PRICE.  The purchase price for the Assets to be
purchased pursuant to the exercise of the Assets Option shall be $1,000 ("Assets
Purchase Price").  The purchase price of any partial purchase of the Assets
shall be a pro-rata percentage of the full Assets Purchase Price.

          (b)  STOCK PURCHASE PRICE.  The purchase price for the Stock to be
purchased pursuant to the exercise of the Stock Option shall be $1,000 ("Stock
Purchase Price").  The purchase price of less than all of the issued and
outstanding Stock is a pro-rata percentage of the full Stock Purchase Price.

     6.2  PAYMENT.  For the Assets, Sierra Medical Management shall pay Group
the Assets Purchase Price at Closing in the form of immediately available funds
transferred by wire to an account at a financial institution designated by
Group.  For the Stock, Sierra Medical Management shall cause the Successor
Physician to pay Prospect Medical Group the Stock Purchase Price.

     6.3  CLOSING.  The transactions contemplated by this Agreement are to close
forty-five (45) days after the date of either the Assets Exercise Notice or the

     9.14 DISPUTE RESOLUTION.  In the event the parties hereto are unable to

agree to arbitrate as set forth below.

          (a)  There shall be one arbitrator.  If the parties shall fail to
select a mutually acceptable arbitrator within ten (10) days after the demand
for arbitration is mailed, then the parties stipulate to arbitration before a
retired judge sitting on the Los Angeles, California, Judicial Arbitration
Mediation Services (JAMS) panel.

          (b)  The substantive law of the State of California shall be applied
by the arbitrator.

          (c)  Arbitration shall take place in Los Angeles, California, unless
Group and a majority of the other parties otherwise agree.  As soon as
reasonably practicable, a hearing with respect to the dispute or matter to be
resolved shall be conducted by the arbitrator.  As soon as reasonably
practicable thereafter, the arbitrator shall arrive at a final decision, which
shall be reduced to writing, signed by the arbitrator and mailed to each of the
parties and their legal counsel.

          (d)  All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement.  The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

          (e)  Notwithstanding the foregoing, because time is of the essence of
this Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar short term
equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or
dissolve such court order.

          (f)  Notwithstanding the foregoing, any and all arbitration
proceedings are conditional upon such proceedings being covered within the
parties' respective risk insurance policies.

     9.15 ATTORNEYS' FEES.  Should any of the parties hereto institute any
action or procedure to enforce this Agreement or any provision hereof (including
without limitation, arbitration), or for damages by reason of any alleged breach
of this Agreement or of any provision hereof, or for a declaration of rights
hereunder (including, without limitation, by means of arbitration), the

                                       9

<PAGE>

prevailing party in any such action or proceeding shall be entitled to receive
from the other party all costs and expenses, including without limitation
reasonable attorneys' fees, incurred by the prevailing party in connection with
such action or proceeding.

     9.16 FURTHER ASSURANCES.  The parties shall take such actions and execute
and deliver such further documentation as may reasonably be required in order to
give effect to the transactions contemplated by this Agreement and the
intentions of the parties hereto.

     9.17 RIGHTS CUMULATIVE.  The various rights and remedies herein granted to
the respective parties hereto shall be cumulative and in addition to any other
rights any such party may be entitled to under law.  The exercise of one or more
rights or remedies by a party shall not impair the right of such party to
exercise any other right or remedy, at law or equity.

     9.18 CONFLICTS. In the event that any provision contained herein shall
conflict with the Credit Succession Agreement, the provision of the Credit
Succession Agreement shall control and such conflicting provision herein shall
be of no further force or effect.

     IN WITNESS WHEREOF, Group, Prospect Medical Group, and Sierra Medical
Management execute this Agreement by their duly authorized representatives as
set forth below.

<PAGE>

     Should interest not be paid when due, it shall thereafter bear like
interest as the principal, but such unpaid interest so compounded shall not
exceed an amount equal to simple interest on the unpaid principal at the maximum
rate permitted by the laws of the State of California.  Purchaser shall at its
option be eligible to receive a one-time six month extension of the Maturity
Date of this Note by delivering written notice of such extension election not
later than thirty (30) days prior to the Maturity Date, with principal payments
continuing and 7% interest to be paid monthly on the unpaid principal.

     Purchaser may assign its obligations under this Note to an affiliate at any
time provided such affiliate accepts such assignment and assumes all of the
obligations set forth herein.  No such assignment shall relieve Purchaser of its
obligations hereunder.  This Note is non-negotiable and may not be assigned by
Holder.

     Holder may waive compliance with any of the provisions of this Note.

     At the option of the holder hereof, this Note shall be immediately due and

amended, or any part thereof, or under any other laws, whether state or 
federal, for the relief of debtors, now or hereafter existing, by any of the 
foregoing parties, or against any of the foregoing parties, which shall not 
be discharged within thirty (30) days of their commencement.

     The Purchaser may, at any time and from time to time, without penalty, 
make prepayments which will be applied to the final payment of principal 
under this Note, or the principal components of the remaining payments under 
this Note in the order or inverse order of maturity, all as the Purchaser 
hereof may determine.  Payment of this Note is guarantied by Prospect Medical 
Holdings.

     In the event AV Hospital, or its affiliates, acquires a portion of 
Purchaser's ownership interest in any affiliate of Company, Purchaser agrees 
to use up to 25% of any cash proceeds from such transaction to prepay, on a 
pro-rata basis, this Note and promissory notes issued to Karunyan 
Arulanantham, M.D. and Jayaratnam Jayakumar, in the principal amounts of 
$1,125,000 and $250,000, respectively.  Purchaser further agrees to prepay

or omission on the part of the holder hereof in exercising any right hereunder
shall operate as a waiver of such right or of any other right under this Note.

     The payments under this Note are subject to the rights of recoupment,

breach of any warranty, or any other breach of the Stock Purchase Agreement by
Holder.  In exercising its rights of recoupment, offset, or setoff, Purchaser
shall not hold back and keep from the total outstanding principal balance more
than the amount of the liability, loss, costs, or expense.

agrees, that, notwithstanding the terms of this Note, the payment of the
principal, interest and any other amounts due under this Note is subordinated,

                  Option to Purchase 15,750 Shares of Common Stock.



                           OPTION TO PURCHASE COMMON STOCK
                                          OF
                           PROSPECT MEDICAL HOLDINGS, INC.


     This is to Certify that, FOR VALUE RECEIVED, Sinnadurai E. Moorthy, M.D.,
or assigns ("Holder"), is entitled to purchase, subject to the provisions of
this Option, from Prospect Medical Holdings, Inc., a Delaware corporation
("Company"), 15,750 shares of Common Stock, $0.01 par value, of the Company
("Common Stock") at a price of $5.00 per share at any time during the period
from the date hereof to five (5) years from the date hereof (the "Expiration
Date"), but not later than 5:00 p.m., New York Time, on the Expiration Date. 
Such number and price may be adjusted from time to time as hereinafter set
forth.  The shares of Common Stock deliverable upon such exercise and as
adjusted from time to time are hereinafter sometimes referred to as "Option
Shares" and the exercise price of each share of Common Stock in effect at any
time and as adjusted from time to time is hereinafter sometimes referred to as
the "Exercise Price".

     (a)  EXERCISE OF OPTION.  Subject to the provisions of Section (j) hereof,
this Option may be exercised in whole or in part at any time or from time to
time on or after the date hereof and until the Expiration Date, or if any such
day is a day on which banking institutions in the State of New York are
authorized by law to close, then on the next succeeding day which shall not be
such a day, by presentation and surrender hereof to the Company at its principal
office, or at the office of its stock transfer agent, if any, with the Purchase
Form annexed hereto duly executed and accompanied by payment of the Exercise
Price for the number of Option Shares specified in such form.  If this Option
should be exercised in part only, the Company shall, upon surrender of this
Option for cancellation, execute and deliver a new Option evidencing the rights
of the Holder thereof to purchase the balance of the Option Shares purchasable
thereunder.  Upon receipt by the Company of this Option at its office, or by the
stock transfer agent of the Company at its office, in proper form for exercise,
the Holder shall be deemed to be the holder of record of the shares of Common
Stock issuable upon such exercise, notwithstanding that the stock transfer books
of the Company shall then be closed or that certificates representing such
shares of Common Stock shall not then be actually delivered to the Holder.

<PAGE>

     (b)  RESERVATION OF SHARES.  The Company hereby agrees that at all times
there shall be reserved for issuance and/or delivery upon exercise of this
Option such number of shares of its Common Stock as shall be required for
issuance and delivery upon exercise of this Option.

     (c)  FRACTIONAL SHARES.  No fractional shares or script representing
fractional shares shall be issued upon the exercise of this Option.  With
respect to any fraction of a share called for upon any exercise hereof, the
Company shall pay to the Holder an amount in cash equal to such fraction
multiplied by the current market value of a share, determined as follows:

          (1)  If the Common Stock is listed on a National Securities Exchange
     or admitted to unlisted trading privileges on such exchange or listed for
     trading on the NASDAQ system, the current market value shall be the last
     reported sale price of the Common Stock on such exchange or system on the
     last business day prior to the date of exercise of this Option or if no
     such sale is made on such day, the average closing bid and asked prices for
     such day on such exchange or system; or

          (2)  If the Common Stock is not so listed or admitted to unlisted
     trading privileges, the current market value shall be the mean of the last
     reported bid and asked prices reported by the National Quotation Bureau,
     Inc. on the last business day prior to the date of the exercise of this
     Option; or

          (3)  If the Common Stock is not so listed or admitted to unlisted
     trading privileges and bid and asked prices are not so reported, the
     current market value shall be an amount not less than the book value
     thereof at the end of the most recent fiscal year of the Company ending
     prior to the date of the exercise of the Option, determined in such
     reasonable manner as may be prescribed by the Board of Directors of the
     Company.

     (d)  EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF OPTION.  This Option is 
exchangeable, without expense, at the option of the Holder, upon presentation 
and surrender hereof to the Company or at the office of its stock transfer 
agent, if any, for other options of different denominations entitling the 
holder thereof to purchase in the aggregate the same number of shares of 
Common Stock purchasable hereunder.  This Option is transferable and may be 
assigned or hypothecated from the date hereof.  Subject to the provisions of 
Section (j), upon surrender of this Option to the Company at its principal 
office or at the office of its stock transfer agent, if any, with the 
Assignment Form annexed hereto duly executed and funds sufficient to pay any 
transfer tax, the Company shall, without charge, execute and deliver a new 
Option in the name of the assignee named in such instrument of assignment and 
this Option shall promptly be canceled.  This Option may be divided or 
combined with other options which carry the same rights upon presentation 
hereof at the principal office of the Company or at the office of its stock 
transfer agent, if any, together with a written notice specifying the names 
and denominations in which new Options are to be issued and signed by the 
Holder hereof.  The term "Option" as used herein includes any Options into 
which this Option may be divided or exchanged.  Upon receipt by the Company 
of evidence satisfactory to it of the loss, theft, destruction or mutilation 
of this Option, and in the case of loss, theft or destruction, of reasonably 

                                     -2-
<PAGE>

satisfactory indemnification and upon surrender and cancellation of this 
Option, if mutilated, the Company will execute and deliver a new Option of 
like tenor and date. 

     (e)  RIGHTS OF THE HOLDER.  The Holder shall not, by virtue hereof, be
entitled to any rights of a shareholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in the Option and
are not enforceable against the Company except to the extent set forth herein. 
Furthermore, Holder by acceptance hereof, consents to and agrees to be bound by
and to comply with all the provisions of this Option, including, without
limitation, all the obligations imposed upon the holder hereof by Section (j). 
In addition, the holder of this Option, by accepting the same, agrees that the
Company and the transfer agent may deem and treat the person in whose name this
Option is registered as the absolute, true and lawful owner for all purposes
whatsoever, and neither the Company nor the transfer agent shall be affected by
any notice to the contrary.

     (f)  ANTI-DILUTION PROVISIONS.  The Exercise Price and the number and kind
of securities purchasable upon the exercise of this Option shall be subject to
adjustment from time to time upon the happening of certain events as hereinafter
provided.  The Exercise Price in effect at any time and the number and kind of
securities purchasable upon exercise of each Option shall be subject to
adjustment as follows:

          (1)  In case the Company shall (i) pay a dividend or make a
     distribution on its shares of Common Stock in shares of Common Stock, (ii)
     subdivide or reclassify its outstanding Common Stock in shares of Common
     Stock into a greater number of shares, or (iii) combine or reclassify its
     outstanding Common Stock into a smaller number of shares, the Exercise
     Price in effect at the time of the record date for such dividend or
     distribution or of the effective date of such subdivision, combination or
     reclassification shall be proportionately adjusted so that the Holder of
     this Option exercised after such date shall be entitled to receive the
     aggregate number and kind of shares which, if this Option had been
     exercised by such Holder immediately prior to such date, he would have
     owned upon such exercise and been entitled to receive upon such dividend,
     subdivision, combination or reclassification.  For example, if the Company
     declares a 2 for 1 stock dividend or stock split and the Exercise Price
     immediately prior to such event was $10.00 per share, the adjusted Exercise
     Price immediately after such event would be $5.00 per share.  Such
     adjustment shall be made successively whenever any event listed above shall
     occur.

          (2)  Whenever the Exercise Price payable upon exercise of each Option
     is adjusted pursuant to Subsection (1) above, the number of Shares
     purchasable upon exercise of this Option shall simultaneously be adjusted
     by multiplying the number of Shares initially issuable upon exercise of
     this Option by the Exercise Price in effect on the date hereof and dividing
     the product so obtained by the Exercise Price, as adjusted.

          (3)  No adjustment in the Exercise Price shall be required unless such
     adjustment would require an increase or decrease of at least five cents
     ($0.05) in such price; provided, however, that any adjustments which by
     reason of this Subsection (3) are 

                                     -3-
<PAGE>

     not required to be made shall be carried forward and taken into account 
     in any subsequent adjustment required to be made hereunder.  All 
     calculations under this Section (f) shall be made to the nearest cent 
     or to the nearest one-hundredth of a share, as the case may be.  
     Anything in this Section (f) to the contrary notwithstanding, the 
     Company shall be entitled, but shall not be required, to make such 
     changes in the Exercise Price, in addition to those required by this 
     Section (f), as it, in its sole discretion, shall determine to be 
     advisable in order that any dividend or distribution in shares of 
     Common Stock, subdivision, reclassification or combination of Common 
     Stock referred to hereinabove in this Section (f) hereafter made by the 
     Company to the holders of its Common Stock shall not result in any tax 
     to the holders of its Common Stock or securities convertible into 
     Common Stock.

          (4)  Whenever the Exercise Price is adjusted, as herein provided, the
     Company shall promptly cause a notice setting forth the adjusted Exercise
     Price and adjusted number of Shares issuable upon exercise of each Option
     to be mailed to the Holder of such Option at the Holder's last address
     appearing in the Option Register, and shall cause a certified copy thereof
     to be mailed to its transfer agent, if any.  The Company may retain a firm
     of independent certified public accountants selected by the Board of
     Directors (who may be the regular accountants employed by the Company) to
     make any computation required by this Section (f), and a certificate signed
     by such firm shall be conclusive evidence of the correctness of such
     adjustment.

          (5)  In the event that at any time, as a result of an adjustment made
     pursuant to Subsection (1) above, the Holder of this Option thereafter
     shall become entitled to receive any shares of the Company, other than
     Common Stock, thereafter the number of such other shares so receivable upon
     exercise of this Option shall be subject to adjustment from time to time in
     a manner and on terms as nearly equivalent as practicable to the provisions
     with respect to the Common Stock contained in Subsection (1) to (3),
     inclusive above.

          (6)  Irrespective of any adjustments in the Exercise Price or the
     number or kind of shares purchasable upon exercise of this Option, Options
     theretofore or thereafter issued may continue to express the same price and
     number and kind of shares as are stated in the similar Options initially
     issuable pursuant to this Agreement.

     (g)  OFFICER'S CERTIFICATE.  Whenever the Exercise Price shall be adjusted
as required by the provisions of the foregoing Section, the Company shall
forthwith file in the custody of its Secretary or an Assistant Secretary at its
principal office and with its stock transfer agent, if any, an officer's
certificate showing the adjusted Exercise Price determined as herein provided,
setting forth in reasonable detail the facts requiring such adjustment,
including a statement of the number of additional shares of Common Stock, if
any, and such other facts as shall be necessary to show the reason for and the
manner of computing such adjustment.  Each such officer's certificate shall be
made available at all reasonable times for inspection by the Holder or any
holder of a Option executed and delivered pursuant to Section (a) and the
Company shall, forthwith after each such adjustment, mail a copy by certified
mail of such certificate to the Holder or any such holder.

                                     -4-
<PAGE>

     (h)  NOTICES TO OPTION HOLDERS.  So long as this Option shall be
outstanding, (i) if Company shall pay any dividend or make any distribution upon
the Common Stock or (ii) if the Company shall offer to the holders of Common
Stock for subscription or purchase by them any share of another class of capital
stock or (iii) if any capital reorganization of the Company, reclassification of
the capital stock of the Company, consolidation or merger of the Company with or
into another corporation, sale, lease, or transfer of all or substantially all
of the property and assets of the Company to another corporation, or voluntary
or involuntary dissolution, liquidation or winding up of the Company shall be
effected, then in any such case, the Company shall cause to be mailed by
certified mail to the Holder, at least fifteen days prior the date specified in
(x) or (y) below, as the case may be, a notice containing a brief description of
the proposed action and stating the date on which (x) a record is to be taken
for the purpose of such dividend, distribution or rights, or (y) such
reclassification, reorganization, consolidation, merger, conveyance, lease,
dissolution, liquidation or winding up is to take place and the date, if any is
to be fixed, as of which the holders of Common Stock or other securities shall
receive cash or other property deliverable upon such reclassification,
reorganization, consolidation, merger, conveyance, dissolution, liquidation or
winding up.

     (i)  RECLASSIFICATION, REORGANIZATION OR MERGER.  In case of any
reclassification, capital reorganization or other change of outstanding shares
of Common Stock of the Company, or in case of any consolidation or merger of the
Company with or into another corporation (other than a merger with a subsidiary
in which merger the Company is the continuing corporation and which does not
result in any reclassification, capital reorganization or other change of
outstanding shares of Common Stock of the class issuable upon exercise of this
Option) or in case of any sale, lease, or conveyance to another corporation of
the property of the Company as an entirety, the Company shall, as a condition
precedent to such transaction, cause effective provisions to be made so that the
Holder shall have the right thereafter by exercising this Option at any time
prior to the expiration of the Option, to purchase the kind and amount of shares
of stock and other securities and property receivable upon such
reclassification, capital reorganization and other change, consolidation,
merger, sale, lease or conveyance by a holder of the number of shares of Common
Stock which might have been purchased upon exercise of this Option immediately
prior to such reclassification, reorganization, change, consolidation, merger,
sale, lease or conveyance.  Any such provision shall include provision for
adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided for in this Option.  The foregoing provisions of this
Section (i) shall similarly apply to successive reclassifications, capital
reorganizations, and changes of shares of Common Stock and to successive
consolidations, mergers, sales, leases or conveyances.  In the event that in
connection with any such capital reorganization or reclassification, change,
consolidation,  merger, sale, lease or conveyance, additional shares of Common
Stock shall be issued in exchange, conversion, substitution, or payment, in
whole or in part, for a security of the Company other than Common Stock, any
such issue shall be treated as an issue of Common Stock covered by the
provisions of Subsection (1) of Section (f) hereof.

     (j)  EXERCISE AND TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933.  The
holder of this Option and any transferee hereof, by their acceptance hereof,
hereby agree that:  (a) the Options being acquired hereunder are being purchased
for investment purposes


                                     -5-
<PAGE>

only and not with a view to distribution and will not be transferred without 
the prior written consent of the Company and unless registered or unless 
there is an exemption available from the registration requirements of the 
Securities Act of 1933, as amended, which exemption has been established to 
the satisfaction of the Company; (b) no public distribution of the Options or 
Option Shares will be made in violation of the provisions of the Securities 
Act of  1933, as amended, or the Rules and Regulations promulgated thereunder 
(such Act and Rules and Regulations being hereinafter referred to as the 
"Act") or any applicable state laws; and (c) during such period as delivery 
of a prospectus with respect to the Options or Option Shares may be required 
by the Act, no public distribution of the Options or Option Shares will be 
made in a manner or on terms different from those set forth in, or without 
delivery of, a prospectus then meeting the requirements of Section 10 of the 
Act and in compliance with all applicable state laws.  The holder of this 
Option and any such transferee hereof further agree that if any distribution 
of any of the Options or Option Shares is proposed to be made by them 
otherwise than by delivery of a prospectus meeting the requirements of 
Section 10 of the Act, such action shall be taken only after submission to 
the Company of an opinion of counsel, reasonably satisfactory in form and 
substance to the Company's counsel, to the effect that the proposed 
distribution will not be in violation of the Act or of applicable state law.  
Furthermore, it shall be a condition to the transfer of the Options or Option 
Shares thereof to deliver to the Company his or its written agreement to 
accept and be bound by all of the terms and conditions of this Option.  
Lastly, the holder of this Option has executed and delivered to the Company a 
Stockholder's Representation Agreement containing certain representations and 
warranties of the holder which are incorporated herein by reference.

     (k)  GOVERNING LAW.  This Option is made with reference to the laws of the
State of California and shall be governed by and construed in accordance
therewith.

     (l)  ARBITRATION. The parties firmly desire to resolve all disputes arising
hereunder without resort to litigation in order to protect their respective
business reputations and the confidential nature of certain aspects of their
relationship.  Accordingly, any controversy or claim arising out of or relating
to this Option, or the breach thereof, shall be settled by arbitration as set
forth below.

          i.   All disputes which in any manner arise out of or relate to this
Option or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section (l).  Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

          ii.  The parties stipulate to arbitration before a single, mutually
agreed upon arbitrator sitting on the Los Angeles, California Judicial
Arbitration Mediation Services (JAMS) panel.  In the event that the parties are
unable to agree upon the person chosen as arbitrator within 30 days of the
demand for arbitration, the arbitrator shall be selected in the sole discretion
of the JAMS administrator.  The arbitrator shall be a member of the California
bar.

                                     -6-
<PAGE>

          iii. The parties shall share all costs of arbitration.  The prevailing
party shall be entitled to reimbursement by the other party of such party's
attorneys' fees and costs and any arbitration fees and expenses incurred in
connection with the arbitration hereunder.

          iv.  The substantive law of the State of California shall be applied
by the arbitrator.  All proceedings in arbitration shall be in accordance with
the California Code of Civil Procedure, as amended, and the parties shall have
the right to legal discovery in any matter submitted to arbitration in
satisfaction of California Code of Civil Procedure Section 1283.05, as permitted
by California Code of Civil Procedure Section 1283.1(b).

          v.   Arbitration shall take place in Los Angeles, California unless
the parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable thereafter, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

          vi.  All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Option.  The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

          vii. Notwithstanding the foregoing, because time is of the essence of
this Option, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar equitable
relief.

          viii.     The decision and award of the arbitrator shall be kept
confidential by the parties to the greatest extent possible.  No disclosure of
such decision or award shall be made by the parties except as required by law or
as necessary or appropriate to effect the enforcement thereof.

          ix.  Should either party institute any action or procedure to enforce
this Option or any provision hereof, or for damages by reason of any alleged
breach of this Option or of any provision hereof, or for a declaration of rights
hereunder (including without limitation arbitration), the prevailing party in
any such action or proceeding shall be entitled to receive from the other party
all costs and expenses, including without limitation reasonable attorneys' fees,
incurred by the prevailing party in connection with such action or proceeding.

THE OPTIONS AND OPTION SHARES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
OF 1933, AS AMENDED, AND THE OPTIONS AND THE OPTION SHARES MAY NOT BE EXERCISED,
OFFERED OR SOLD UNLESS THERE IS A REGISTRATION STATEMENT IN EFFECT COVERING THE
OPTIONS AND OPTION SHARES OR THERE IS AVAILABLE AN EXEMPTION FROM THE
REGISTRATION REQUIREMENTS OF THE SECURITIES ACT OF 1933, AS AMENDED.


              Void after 5:00 p.m. New York Time, on September 24, 2002.
                  Option to Purchase 15,750 Shares of Common Stock.



                           OPTION TO PURCHASE COMMON STOCK
                                          OF
                           PROSPECT MEDICAL HOLDINGS, INC.


     This is to Certify that, FOR VALUE RECEIVED, Karunyan Arulanantham, M.D.,
or assigns ("Holder"), is entitled to purchase, subject to the provisions of
this Option, from Prospect Medical Holdings, Inc., a Delaware corporation
("Company"), 15,750 shares of Common Stock, $0.01 par value, of the Company
("Common Stock") at a price of $5.00 per share at any time during the period
from the date hereof to five (5) years from the date hereof (the "Expiration
Date"), but not later than 5:00 p.m., New York Time, on the Expiration Date. 
Such number and price may be adjusted from time to time as hereinafter set
forth.  The shares of Common Stock deliverable upon such exercise and as
adjusted from time to time are hereinafter sometimes referred to as "Option
Shares" and the exercise price of each share of Common Stock in effect at any
time and as adjusted from time to time is hereinafter sometimes referred to as
the "Exercise Price".

     (a)  EXERCISE OF OPTION.  Subject to the provisions of Section (j) hereof,
this Option may be exercised in whole or in part at any time or from time to
time on or after the date hereof and until the Expiration Date, or if any such
day is a day on which banking institutions in the State of New York are
authorized by law to close, then on the next succeeding day which shall not be
such a day, by presentation and surrender hereof to the Company at its principal
office, or at the office of its stock transfer agent, if any, with the Purchase
Form annexed hereto duly executed and accompanied by payment of the Exercise
Price for the number of Option Shares specified in such form.  If this Option
should be exercised in part only, the Company shall, upon surrender of this
Option for cancellation, execute and deliver a new Option evidencing the rights
of the Holder thereof to purchase the balance of the Option Shares purchasable
thereunder.  Upon receipt by the Company of this Option at its office, or by the
stock transfer agent of the Company at its office, in proper form for exercise,
the Holder shall be deemed to be the holder of record of the shares of Common
Stock issuable upon such exercise, notwithstanding that the stock transfer books
of the Company shall then be closed or that certificates representing such
shares of Common Stock shall not then be actually delivered to the Holder.

<PAGE>

     (b)  RESERVATION OF SHARES.  The Company hereby agrees that at all times
there shall be reserved for issuance and/or delivery upon exercise of this
Option such number of shares of its Common Stock as shall be required for
issuance and delivery upon exercise of this Option.

     (c)  FRACTIONAL SHARES.  No fractional shares or script representing
fractional shares shall be issued upon the exercise of this Option.  With
respect to any fraction of a share called for upon any exercise hereof, the
Company shall pay to the Holder an amount in cash equal to such fraction
multiplied by the current market value of a share, determined as follows:

          (1)  If the Common Stock is listed on a National Securities Exchange
     or admitted to unlisted trading privileges on such exchange or listed for
     trading on the NASDAQ system, the current market value shall be the last
     reported sale price of the Common Stock on such exchange or system on the
     last business day prior to the date of exercise of this Option or if no
     such sale is made on such day, the average closing bid and asked prices for
     such day on such exchange or system; or

          (2)  If the Common Stock is not so listed or admitted to unlisted
     trading privileges, the current market value shall be the mean of the last
     reported bid and asked prices reported by the National Quotation Bureau,
     Inc. on the last business day prior to the date of the exercise of this
     Option; or

          (3)  If the Common Stock is not so listed or admitted to unlisted
     trading privileges and bid and asked prices are not so reported, the
     current market value shall be an amount not less than the book value
     thereof at the end of the most recent fiscal year of the Company ending
     prior to the date of the exercise of the Option, determined in such
     reasonable manner as may be prescribed by the Board of Directors of the
     Company.

     (d)  EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF OPTION.  This Option is 
exchangeable, without expense, at the option of the Holder, upon presentation 
and surrender hereof to the Company or at the office of its stock transfer 
agent, if any, for other options of different denominations entitling the 
holder thereof to purchase in the aggregate the same number of shares of 
Common Stock purchasable hereunder.  This Option is transferable and may be 
assigned or hypothecated from the date hereof.  Subject to the provisions of 
Section (j), upon surrender of this Option to the Company at its principal 
office or at the office of its stock transfer agent, if any, with the 
Assignment Form annexed hereto duly executed and funds sufficient to pay any 
transfer tax, the Company shall, without charge, execute and deliver a new 
Option in the name of the assignee named in such instrument of assignment and 
this Option shall promptly be canceled.  This Option may be divided or 
combined with other options which carry the same rights upon presentation 
hereof at the principal office of the Company or at the office of its stock 
transfer agent, if any, together with a written notice specifying the names 
and denominations in which new Options are to be issued and signed by the 
Holder hereof.  The term "Option" as used herein includes any Options into 
which this Option may be divided or exchanged.  Upon receipt by the Company 
of evidence satisfactory to it of the loss, theft, destruction or mutilation 
of this Option, and in the case of loss, theft or destruction, of reasonably 

                                     -2-
<PAGE>

satisfactory indemnification and upon surrender and cancellation of this 
Option, if mutilated, the Company will execute and deliver a new Option of 
like tenor and date. 

     (e)  RIGHTS OF THE HOLDER.  The Holder shall not, by virtue hereof, be
entitled to any rights of a shareholder in the Company, either at law or equity,
and the rights of the Holder are limited to those expressed in the Option and
are not enforceable against the Company except to the extent set forth herein. 
Furthermore, Holder by acceptance hereof, consents to and agrees to be bound by
and to comply with all the provisions of this Option, including, without
limitation, all the obligations imposed upon the holder hereof by Section (j). 
In addition, the holder of this Option, by accepting the same, agrees that the
Company and the transfer agent may deem and treat the person in whose name this
Option is registered as the absolute, true and lawful owner for all purposes
whatsoever, and neither the Company nor the transfer agent shall be affected by
any notice to the contrary.

     (f)  ANTI-DILUTION PROVISIONS.  The Exercise Price and the number and kind
of securities purchasable upon the exercise of this Option shall be subject to
adjustment from time to time upon the happening of certain events as hereinafter
provided.  The Exercise Price in effect at any time and the number and kind of
securities purchasable upon exercise of each Option shall be subject to
adjustment as follows:

          (1)  In case the Company shall (i) pay a dividend or make a
     distribution on its shares of Common Stock in shares of Common Stock, (ii)
     subdivide or reclassify its outstanding Common Stock in shares of Common
     Stock into a greater number of shares, or (iii) combine or reclassify its
     outstanding Common Stock into a smaller number of shares, the Exercise
     Price in effect at the time of the record date for such dividend or
     distribution or of the effective date of such subdivision, combination or
     reclassification shall be proportionately adjusted so that the Holder of
     this Option exercised after such date shall be entitled to receive the
     aggregate number and kind of shares which, if this Option had been
     exercised by such Holder immediately prior to such date, he would have
     owned upon such exercise and been entitled to receive upon such dividend,
     subdivision, combination or reclassification.  For example, if the Company
     declares a 2 for 1 stock dividend or stock split and the Exercise Price
     immediately prior to such event was $10.00 per share, the adjusted Exercise
     Price immediately after such event would be $5.00 per share.  Such
     adjustment shall be made successively whenever any event listed above shall
     occur.

          (2)  Whenever the Exercise Price payable upon exercise of each Option
     is adjusted pursuant to Subsection (1) above, the number of Shares
     purchasable upon exercise of this Option shall simultaneously be adjusted
     by multiplying the number of Shares initially issuable upon exercise of
     this Option by the Exercise Price in effect on the date hereof and dividing
     the product so obtained by the Exercise Price, as adjusted.

          (3)  No adjustment in the Exercise Price shall be required unless such
     adjustment would require an increase or decrease of at least five cents
     ($0.05) in such price; provided, however, that any adjustments which by
     reason of this Subsection (3) are 

                                     -3-
<PAGE>

     not required to be made shall be carried forward and taken into account 
     in any subsequent adjustment required to be made hereunder.  All 
     calculations under this Section (f) shall be made to the nearest cent 
     or to the nearest one-hundredth of a share, as the case may be.  
     Anything in this Section (f) to the contrary notwithstanding, the 
     Company shall be entitled, but shall not be required, to make such 
     changes in the Exercise Price, in addition to those required by this 
     Section (f), as it, in its sole discretion, shall determine to be 
     advisable in order that any dividend or distribution in shares of 
     Common Stock, subdivision, reclassification or combination of Common 
     Stock referred to hereinabove in this Section (f) hereafter made by the 
     Company to the holders of its Common Stock shall not result in any tax 
     to the holders of its Common Stock or securities convertible into 
     Common Stock.

          (4)  Whenever the Exercise Price is adjusted, as herein provided, the
     Company shall promptly cause a notice setting forth the adjusted Exercise
     Price and adjusted number of Shares issuable upon exercise of each Option
     to be mailed to the Holder of such Option at the Holder's last address
     appearing in the Option Register, and shall cause a certified copy thereof
     to be mailed to its transfer agent, if any.  The Company may retain a firm
     of independent certified public accountants selected by the Board of
     Directors (who may be the regular accountants employed by the Company) to
     make any computation required by this Section (f), and a certificate signed
     by such firm shall be conclusive evidence of the correctness of such
     adjustment.

          (5)  In the event that at any time, as a result of an adjustment made
     pursuant to Subsection (1) above, the Holder of this Option thereafter
     shall become entitled to receive any shares of the Company, other than
     Common Stock, thereafter the number of such other shares so receivable upon
     exercise of this Option shall be subject to adjustment from time to time in

     with respect to the Common Stock contained in Subsection (1) to (3),
     inclusive above.

          (6)  Irrespective of any adjustments in the Exercise Price or the
     number or kind of shares purchasable upon exercise of this Option, Options
     theretofore or thereafter issued may continue to express the same price and
     number and kind of shares as are stated in the similar Options initially
     issuable pursuant to this Agreement.

     (g)  OFFICER'S CERTIFICATE.  Whenever the Exercise Price shall be adjusted
as required by the provisions of the foregoing Section, the Company shall
forthwith file in the custody of its Secretary or an Assistant Secretary at its
principal office and with its stock transfer agent, if any, an officer's
certificate showing the adjusted Exercise Price determined as herein provided,
setting forth in reasonable detail the facts requiring such adjustment,
including a statement of the number of additional shares of Common Stock, if
any, and such other facts as shall be necessary to show the reason for and the
manner of computing such adjustment.  Each such officer's certificate shall be
made available at all reasonable times for inspection by the Holder or any
holder of a Option executed and delivered pursuant to Section (a) and the
Company shall, forthwith after each such adjustment, mail a copy by certified
mail of such certificate to the Holder or any such holder.

     (h)  NOTICES TO OPTION HOLDERS.  So long as this Option shall be 
outstanding, (i) if Company shall pay any dividend or make any distribution 
upon the Common Stock or (ii) if the Company shall offer to the holders of 
Common Stock for subscription or purchase by them any share of another class 
of capital stock or (iii) if any capital reorganization of the Company, 
reclassification of the capital stock of the Company, consolidation or merger 
of the Company with or into another corporation, sale, lease, or transfer of 
all or substantially all of the property and assets of the Company to another 
corporation, or voluntary or involuntary dissolution, liquidation or winding 
up of the Company shall be effected, then in any such case, the Company shall 
cause to be mailed by certified mail to the Holder, at least fifteen days 
prior the date specified in (x) or (y) below, as the case may be, a notice 
containing a brief description of the proposed action and stating the date on 
which (x) a record is to be taken for the purpose of such dividend, 
distribution or rights, or (y) such reclassification, reorganization, 
consolidation, merger, conveyance, lease, dissolution, liquidation or winding 
up is to take place and the date, if any is to be fixed, as of which the 
holders of Common Stock or other securities shall receive cash or other 
property deliverable upon such reclassification, reorganization, 
consolidation, merger, conveyance, dissolution, liquidation or winding up.

     (i)  RECLASSIFICATION, REORGANIZATION OR MERGER.  In case of any 
reclassification, capital reorganization or other change of outstanding 
shares of Common Stock of the Company, or in case of any consolidation or 
merger of the Company with or into another corporation (other than a merger 
with a subsidiary in which merger the Company is the continuing corporation 
and which does not result in any reclassification, capital reorganization or 
other change of outstanding shares of Common Stock of the class issuable upon 
exercise of this Option) or in case of any sale, lease, or conveyance to 
another corporation of the property of the Company as an entirety, the 
Company shall, as a condition precedent to such transaction, cause effective 
provisions to be made so that the Holder shall have the right thereafter by 
exercising this Option at any time prior to the expiration of the Option, to 
purchase the kind and amount of shares of stock and other securities and 
property receivable upon such reclassification, capital reorganization and 
other change, consolidation, merger, sale, lease or conveyance by a holder of 
the number of shares of Common Stock which might have been purchased upon 
exercise of this Option immediately prior to such reclassification, 
reorganization, change, consolidation, merger, sale, lease or conveyance.  
Any such provision shall include provision for adjustments which shall be as 
nearly equivalent as may be practicable to the adjustments provided for in 
this Option.  The foregoing provisions of this Section (i) shall similarly 
apply to successive reclassifications, capital reorganizations, and changes 
of shares of Common Stock and to successive consolidations, mergers, sales, 
leases or conveyances.  In the event that in connection with any such capital 
reorganization or reclassification, change, consolidation,  merger, sale, 
lease or conveyance, additional shares of Common Stock shall be issued in 
exchange, conversion, substitution, or payment, in whole or in part, for a 
security of the Company other than Common Stock, any such issue shall be 
treated as an issue of Common Stock covered by the provisions of Subsection 
(1) of Section (f) hereof.

     (j)  EXERCISE AND TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933.  
The holder of this Option and any transferee hereof, by their acceptance 
hereof, hereby agree that:  (a) the Options being acquired hereunder are 
being purchased for investment purposes 


                                     -5-
<PAGE>

only and not with a view to distribution and will not be transferred without 
the prior written consent of the Company and unless registered or unless 
there is an exemption available from the registration requirements of the 
Securities Act of 1933, as amended, which exemption has been established to 
the satisfaction of the Company; (b) no public distribution of the Options or 
Option Shares will be made in violation of the provisions of the Securities 
Act of  1933, as amended, or the Rules and Regulations promulgated thereunder 
(such Act and Rules and Regulations being hereinafter referred to as the 
"Act") or any applicable state laws; and (c) during such period as delivery 
of a prospectus with respect to the Options or Option Shares may be required 
by the Act, no public distribution of the Options or Option Shares will be 
made in a manner or on terms different from those set forth in, or without 
delivery of, a prospectus then meeting the requirements of Section 10 of the 
Act and in compliance with all applicable state laws.  The holder of this 
Option and any such transferee hereof further agree that if any distribution 
of any of the Options or Option Shares is proposed to be made by them 
otherwise than by delivery of a prospectus meeting the requirements of 
Section 10 of the Act, such action shall be taken only after submission to 
the Company of an opinion of counsel, reasonably satisfactory in form and 
substance to the Company's counsel, to the effect that the proposed 
distribution will not be in violation of the Act or of applicable state law.  
Furthermore, it shall be a condition to the transfer of the Options or Option 
Shares thereof to deliver to the Company his or its written agreement to 
accept and be bound by all of the terms and conditions of this Option.  
Lastly, the holder of this Option has executed and delivered to the Company a 
Stockholder's Representation Agreement containing certain representations and 
warranties of the holder which are incorporated herein by reference.

     (k)  GOVERNING LAW.  This Option is made with reference to the laws of 
the State of California and shall be governed by and construed in accordance 
therewith.

     (l)  ARBITRATION. The parties firmly desire to resolve all disputes 
arising hereunder without resort to litigation in order to protect their 
respective business reputations and the confidential nature of certain 
aspects of their relationship.  Accordingly, any controversy or claim arising 
out of or relating to this Option, or the breach thereof, shall be settled by 
arbitration as set forth below.

          i.   All disputes which in any manner arise out of or relate to this
Option or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section (l).  Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

          ii.  The parties stipulate to arbitration before a single, mutually
agreed upon arbitrator sitting on the Los Angeles, California Judicial
Arbitration Mediation Services (JAMS) panel.  In the event that the parties are
unable to agree upon the person chosen as arbitrator within 30 days of the
demand for arbitration, the arbitrator shall be selected in the sole discretion
of the JAMS administrator.  The arbitrator shall be a member of the California
bar.

                                     -6-
<PAGE>

          iii. The parties shall share all costs of arbitration.  The prevailing
party shall be entitled to reimbursement by the other party of such party's
attorneys' fees and costs and any arbitration fees and expenses incurred in
connection with the arbitration hereunder.

          iv.  The substantive law of the State of California shall be applied
by the arbitrator.  All proceedings in arbitration shall be in accordance with
the California Code of Civil Procedure, as amended, and the parties shall have
the right to legal discovery in any matter submitted to arbitration in
satisfaction of California Code of Civil Procedure Section 1283.05, as permitted
by California Code of Civil Procedure Section 1283.1(b).

          v.   Arbitration shall take place in Los Angeles, California unless
the parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable thereafter, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

          vi.  All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Option.  The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

          vii. Notwithstanding the foregoing, because time is of the essence of
this Option, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar equitable
relief.

          viii.     The decision and award of the arbitrator shall be kept
confidential by the parties to the greatest extent possible.  No disclosure of
such decision or award shall be made by the parties except as required by law or
as necessary or appropriate to effect the enforcement thereof.

          ix.  Should either party institute any action or procedure to enforce
this Option or any provision hereof, or for damages by reason of any alleged
breach of this Option or of any provision hereof, or for a declaration of rights
hereunder (including without limitation arbitration), the prevailing party in
any such action or proceeding shall be entitled to receive from the other party
all costs and expenses, including without limitation reasonable attorneys' fees,
incurred by the prevailing party in connection with such action or proceeding.

which are authorized by Guarantor:


                                          13
<PAGE>

               (a)  settle or adjust disputes and claims directly with Account
Debtors for amounts and upon terms which Agent considers advisable, and in such
cases, Agent will credit the Secured Obligations with only the net amounts
received by Agent in payment of such disputed Accounts after deducting all Agent
Expenses incurred or expended in connection therewith;

               (b)  cause Guarantor to hold all returned Inventory in trust for
Agent, segregate all returned Inventory from all other property of Guarantor or
in Guarantor's possession and conspicuously label said returned Inventory as the
property of Agent;

               (c)  without notice to or demand upon Guarantor or any guarantor,
make such payments and do such acts as Agent considers necessary or unable to
protect its security interests in the Collateral.  Guarantor agrees to assemble
the Collateral if Agent so requires, and to make the Collateral available to
Agent as Agent may designate.  Guarantor authorizes Agent to enter the premises
where the Collateral is located, to take and maintain possession of the
Collateral, or any part of it, and to pay, purchase, contest, or compromise any
encumbrance, charge, or lien that in Agent's determination appears to conflict
with its security interests and to pay all expenses incurred in connection
therewith.  With respect to any of Guarantor's owned or leased premises,
Guarantor hereby grants Agent a license to enter into possession of such
premises and to occupy the same, without charge, for up to 120 days in order to
exercise any of Agent's rights or remedies provided herein, at law, in equity,
or otherwise;

               (d)  ship, reclaim, recover, store, finish, maintain, repair,
prepare for sale, advertise for sale, and sell (in the manner provided for
herein) the Collateral.  Agent is hereby granted a license or other right to
use, without charge, Guarantor's labels, patents, copyrights, rights of use of
any name, trade secrets, trade names, trademarks, service marks, and advertising
matter, or any property of a similar nature, as it pertains to the Collateral,
in completing production of, advertising for sale, and selling any Collateral
and Guarantor's rights under all licenses and all franchise agreements shall
inure to Agent's benefit;

               (e)  sell the Collateral at either a public or private sale, or
both, by way of one or more contracts or transactions, for cash or on terms, in
such manner and at such places (including Guarantor's premises) as Agent
determines is commercially reasonable.  It is not necessary that the Collateral
be present at any such sale;

               (f)  agent shall give notice of the disposition of the Collateral
as follows:

                    (i)  agent shall give Guarantor and each holder of a
security interest in the Collateral who has filed with Agent a written request
for notice, a notice in writing of the time and place of public sale, or, if the
sale is a private sale or some other disposition other than a public sale is to
be made of the Collateral, then the time on or after which the private sale or
other disposition is to be made;


                                          14
<PAGE>

                    (ii) the notice shall be personally delivered or mailed,
postage prepaid, to Guarantor as provided in SECTION 15 of the Guaranty, at
least 5 days before the date fixed for the sale, or at least 5 days before the
date on or after which the private sale or other disposition is to be made; no
notice needs to be given prior to the disposition of any portion of the
Collateral that is perishable or threatens to decline speedily in value or that
is of a customarily sold on a recognized market.  Notice to persons other than
Guarantor claiming an interest in the Collateral shall be sent to such addresses
as they have furnished to Agent;

                    (iii)     if the sale is to be a public sale, Agent also
shall give notice of the time and place by publishing a notice one time at least
5 days before the date of the sale in a newspaper of general circulation in the
county in which the sale is to be held;

               (g)  agent may credit bid and purchase at any public sale; and

               (h)  any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Guarantor.  Any excess
will be returned, without interest and subject to the rights of third persons,
by Agent to Guarantor.

          9.2  Upon the exercise by Agent of any power, right, privilege, or
remedy pursuant to this Security Agreement which requires any consent, approval,
registration, qualification, or authorization of any governmental authority,
Guarantor agrees to execute and deliver, or will cause the execution and
delivery of, all applications, certificates, instruments, assignments, and other
documents and papers that Agent or any purchaser of the Collateral may be
required to obtain for such governmental consent, approval, registration,
qualification, or authorization.

          9.3  The rights and remedies of Agent under this Security Agreement,
the Guaranty,  and all other agreements contemplated hereby and thereby shall be
cumulative.  Agent shall have all other rights and remedies not inconsistent
herewith as provided under the UCC, by law, or in equity.  No exercise by Agent
of any one right or remedy shall be deemed an election of remedies, and no
waiver by Agent of any default on Guarantor's part shall be deemed a continuing
waiver of any further defaults.  No delay by Agent shall constitute a waiver,
election or acquiescence with respect to any right or remedy.

     10.  AGENT NOT LIABLE.  So long as Agent complies with the obligations, if
any, imposed by Section 9207 of the Code, Agent shall not otherwise be liable or
responsible in any way or manner for:  (a) the safekeeping of the Collateral;
(b) any loss or damage thereto occurring or arising in any manner or fashion or
from any cause; (c) any diminution in the value thereof; or (d) any act or
default of any carrier, warehouseman, bailee, forwarding agency, or other person
whomsoever.

     11.  INDEFEASIBLE PAYMENT.  The Secured Obligations shall not be considered

law.

     15.  ARBITRATION.

     The parties firmly desire to resolve all disputes arising hereunder without
resort to litigation in order to protect their respective business reputations
and the confidential nature of certain aspects of their relationship.
Accordingly, any controversy or claim arising out of or relating to this
Agreement, or the breach thereof, shall be settled by arbitration as set forth
below.

          (a)  All disputes which in any manner arise out of or relate to this
Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 15.  Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

          (b)  The parties stipulate to arbitration before a single, mutually
agreed upon arbitrator sitting on the Los Angeles, California Judicial
Arbitration Mediation Services (JAMS) panel.  In the event that the parties are
unable to agree upon the person chosen as arbitrator within 30 days of the
demand for arbitration, the arbitrator shall be selected in the sole discretion
of the JAMS administrator.  The arbitrator shall be a member of the California
bar.

          (c)  The parties shall share all costs of arbitration.  The prevailing
party shall be entitled to reimbursement by the other party of such party's
attorneys' fees and costs and any arbitration fees and expenses incurred in
connection with the arbitration hereunder.

<PAGE>

          (d)  The substantive law of the State of California shall be applied
by the arbitrator.  All proceedings in arbitration shall be in accordance with
the California Code of Civil Procedure, as amended, and the parties shall have
the right to legal discovery in any matter submitted to arbitration in
satisfaction of California Code of Civil Procedure Section 1283.05, as permitted
by California Code of Civil Procedure Section 1283.1(b).

          (e)  Arbitration shall take place in Los Angeles, California unless
the parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable thereunder, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

          (f)  All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement.  The
arbitrator or a court of appropriate jurisdiction may issue a write of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

          (g)  Notwithstanding the foregoing, because time is of the essence of
this Agreement, the parties specifically reserve the right to a judicial
temporary restraining order, preliminary injunction, or other similar equitable
relief.

          (h)  The decision and award of the arbitrator shall be kept
confidential by the parties to the greatest extent possible.  No disclosure of
such decision or award shall be made by the parties except as required by law or
as necessary or appropriate to effect the enforcement thereof.

          (i)  Should either party institute any action or procedure to enforce
this Agreement or any provision hereof, or for damages by reason of any alleged
breach of this Agreement or of any provision hereof, or for a declaration of
rights hereunder (including, without limitation, arbitration), the prevailing
party in any such action or proceeding shall be entitled to


                                          18
<PAGE>

receive from the other party all costs and expenses, including, without
limitation, reasonable attorneys' fees, incurred by the prevailing party in
connection with such action or proceeding.

     IN WITNESS WHEREOF, the parties have executed this Security Agreement as of
the date first set forth above.

     NOW, THEREFORE, in consideration of the mutual covenants and conditions
hereinafter set forth and in exchange for good and valuable consideration, the
receipt and sufficiency of which are hereby acknowledged, the parties agree as
follows:


                                          2
<PAGE>


                                      AGREEMENT

     1.   PREMISES.  Pursuant to the Master Lease specified below, Manager shall
provide GROUP with adequate administrative office space at the addresses
described therein (the "Premises") and Group shall retain all of its remaining
facilities for the operation of the Practice with leasehold improvements,
auxiliary services and utilities in order that GROUP may effectively perform its
functions and duties.

          In consideration of the sums to be paid to Manager under the terms of
this Agreement, Manager hereby leases to GROUP during the term of this Agreement
the furniture, fixtures and equipment (the "FF&E") listed on Exhibit "B"
attached hereto and incorporated herein by this reference, under the following
terms and conditions:

          1.1.   Manager is the lessee under certain leases for the Premises
(hereinafter collectively referred to as the "Master Lease") copies of which are
attached hereto as Exhibit "A" and incorporated herein by this reference.  GROUP
hereby acknowledges that the Premises described in the Master Lease are suitable
for the administrative office of the Practice.  Based and contingent upon
GROUP's promise to timely pay all amounts due under this Agreement, Manager
hereby agrees to sublease the leased Premises to GROUP upon the following terms
and conditions:

                 1.1.1.     This sublease between Manager and GROUP of the
Premises shall be subject to all of the terms and conditions of the Master
Lease.  In the event of the termination of Manager's interest as lessee under
the Master Lease for any reason, then the sublease created hereby shall
simultaneously terminate unless GROUP is willing to assume the obligations under
the Master Lease and the Lessor consents thereto.

                 1.1.2.     All of the terms and conditions contained in the
Master Lease are incorporated herein as terms and conditions of the sublease
(with each reference therein to "Lessor" and "Lessee," to be deemed to refer to
Manager and GROUP, respectively) and, along with the provisions of this Section
1.1 and Exhibit "A," shall be the complete terms and conditions of the sublease
created hereby.

                 1.1.3.     Notwithstanding the foregoing, as between Manager
and GROUP, Manager shall remain responsible for meeting the financial
obligations of "Lessee" under the Master Lease, and GROUP shall have no monetary
obligation in that regard.  In addition, as between Manager and GROUP, Manager
shall retain all rights to exercise any options to purchase the Premises, or
other similar rights of ownership or possession, which may be granted under the
Master Lease, and GROUP shall have no rights in that regard.

                 1.1.4.     In the event this Agreement is terminated according
to its terms, this sublease shall also terminate automatically.

                 1.1.5.     If the Master Lease contains an option to renew the
term thereof, Manager shall notify GROUP, at least thirty (30) days prior to the
expiration of the time for exercising such option, of Manager's intention to
renew or not to renew such term.  If Manager


                                          3
<PAGE>

determines not to renew such term, Manager shall, at GROUP's option and upon the
consent of the Landlord in accordance with the terms of the Master Lease, assign
the Master Lease to GROUP, including Manager's right to renew the term thereof.

     2.   PROVISION OF FURNITURE, FURNISHINGS AND EQUIPMENT ("FF&E").  Manager
hereby provides to GROUP, and GROUP hereby leases from Manager, all the FF&E,
which FF&E GROUP agrees are suitable and sufficient for GROUP's use in the
operation of GROUP's medical practice at the Premises and are generally in good
repair.  The use by GROUP of said FF&E shall be subject to the following
conditions:

          2.1.   Title to all of the FF&E shall remain in Manager at all times,
and upon the termination of this Management Services Agreement, GROUP shall
immediately surrender the FF&E to Manager in as good condition as of the date
hereof, normal wear and tear excepted.  Alternatively, GROUP, in its sole
discretion, shall have the option to purchase any or all of the FF&E upon
termination hereof.  GROUP shall exercise such option, if at all, by giving
Manager written notice of same (the "Notice") within twenty (20) days of the
effective date of termination hereof.  Upon exercise of such option, Manager
shall convey to GROUP within thirty (30) days of the effective date of
termination hereof, all of the FF&E identified in the Notice, together with (i)
any manufacturer's warranties that Manager has received in connection with such
FF&E and (ii) a bill of sale or such other instrument of conveyance as is
reasonably necessary to accomplish said purchase; and GROUP shall simultaneously
convey to Manager the purchase price for said FF&E.  The purchase price shall be
paid all in cash, and shall equal the fair market value of the FF&E.

          2.2.   Manager shall be responsible for all repairs and maintenance
of the FF&E other than damage caused by negligence or willful misuse by GROUP;
provided, however, GROUP shall employ reasonable efforts to prevent damage to
and excessive wear of the FF&E, and shall promptly notify Manager of any needed
repairs thereto.

          2.3.   Manager shall be responsible for all property taxes and other
assessments relating to or arising out of ownership or use of the FF&E that
accrue on and after the date hereof.

          2.4.   Manager shall provide and maintain, at its expense, such
additional or replacement FF&E as the Practice reasonably requires from time to
time, as determined by Manager in its sole discretion, in consultation with
GROUP.  Such additional or replacement FF&E shall be subject to all of the terms
of Section 2.1 above.

          2.5.   GROUP may provide additional equipment at the Practice ("GROUP
Equipment") at its sole cost and expense.  GROUP shall be responsible for all
repairs, maintenance and replacement of, as well as all property taxes and other
assessments relating to or arising out of ownership or use of, such additional
equipment, unless GROUP requests that Manager provide such repairs, maintenance
and replacement upon such terms and conditions as the parties may agree
including, without limitation, an increase in the Management Fee (as defined in
Section 9 below).  Title to said GROUP Equipment shall remain in GROUP's name at
all times.

shall not be liable to GROUP and shall not be deemed to be in default hereunder

God, or any other event which is beyond the reasonable control of Manager or
which was not reasonably foreseeable by Manager.

     4.   RESPONSIBILITIES OF GROUP.

          4.1.   GROUP covenants and agrees that, at all times during the term

activities required by its Articles of Incorporation and Bylaws, including but
not limited to election of a Board of Directors, election of Officers,
appointment of committee members including but not limited to the Quality and
Utilization Management Committee.  In addition, GROUP agrees to appoint a
Medical Director.  GROUP shall be solely responsible for payment of any and all
compensation, payroll taxes, fringe benefits, disability insurance, workers'
compensation insurance and any other benefits of all such individuals.

          4.2.   GROUP shall not enter into any agreements with Participating
Providers unless such Participating Providers have: (i) current unrestricted
licenses to practice their respective professions in the State of California and
(ii) current unrestricted Federal Drug Enforcement Agency ("DEA") numbers.  In
addition, where GROUP contracts with individual physicians, such physicians
shall have medical staff membership at the hospitals required by Participating
Plans and where GROUP contracts with licensed clinics and medical groups, at
least one primary care physician practicing at each clinic or medical group
shall have medical staff membership at the hospitals required by Participating
Plans.  GROUP further agrees to establish procedures to ensure that
Participating Providers meet these requirements on an ongoing basis.  Manager

shall retain ultimate responsibility for meeting such obligations.

          4.3.   GROUP acknowledges and agrees that it is solely responsible
for making all required reports to the Medical Board of California under Section
805 of the California Business and Professions Code and the National
Practitioner Data Bank.

          4.4.   GROUP shall, at its sole cost and expense, procure and
maintain at all times during the term of this Agreement comprehensive general
and professional liability insurance covering all activities of GROUP directly
or indirectly relating to GROUP, each policy in a minimum amount of
$1,000,000.00 per occurrence and $3,000,000.00 in the aggregate.  The
aforedescribed comprehensive general and professional liability insurance shall
be issued by a company or companies authorized to do business in California with
a financial rating of at least A:12 or better in "Best's Key Rating Guide" or
its equivalent.  In the event GROUP procures a "claims made" policy as
distinguished from an "occurrence" policy, GROUP shall procure and maintain at
its sole cost and expense, prior to termination of such insurance, "tail"
coverage to continue and extend coverage complying with this Agreement after the
end of the "claims made"


                                          12

policy.  Upon reasonable request from Manager, GROUP shall cause to be issued to
Manager proper certificates of insurance, evidencing that the foregoing
provisions of this Agreement have been complied with, and said certificates
shall provide that prior to any cancellation or change in the underlying
insurance during the policy period, the insurance carrier shall first give
thirty (30) calendar days written notice to Manager.

maintain professional liability insurance with minimum coverage amounts of
$1,000,000.00 per occurrence and $3,000,000.00 in the aggregate.  GROUP shall
ensure that any Participating Provider who procures insurance required hereunder
on a "claims made" rather than an "occurrences" form will obtain either extended
reporting insurance coverage ("tail coverage") with liability limits equal to
those most recently in effect prior to the day of termination of such
Participating Provider's contract with GROUP, or will enter into such other
arrangements as shall reasonably assure the maintenance of coverage for such
Provider, GROUP, and Manager against the risk of loss in respect of professional
services rendered by such provider while this Agreement was in effect and for a
period of not less than seven (7) years after the date of termination of this
Agreement.

          4.7.   GROUP acknowledges and agrees that it shall reasonably assist
and cooperate with Manager to meet all of Manager's obligations under this
Agreement, including approval of agreements and provision of information.  GROUP

Agreement shall terminate automatically and immediately upon the expiration of
said sixty (60) calendar day period; provided, however, that if the obligation
which Manager fails to perform is other than the failure to make payment of
money, and greater than sixty (60) calendar days are required to perform said
obligation, then such party shall not be in default of this Agreement and the
Agreement shall not terminate as provided hereinabove if such party commences
performance within said sixty day period and diligently pursues said obligation
to completion.

                 5.2.3. Either party may terminate this Agreement for cause at

calendar days after its


                                          14
<PAGE>

entry, termination shall be effective automatically and immediately upon the
occurrence of the foregoing.

          5.3.   JEOPARDY.  In the event the performance by either party hereto

negotiate an amendment to this Agreement to remove or negate the effect of the
Jeopardy Event.  In the event the parties are unable to negotiate such an

reimbursed its Costs (as defined in Exhibit D attached hereto) and paid a
management fee (the "Management Fee") in the amount set forth on Exhibit D

meet its financial obligations.  Such loan shall bear interest at a rate that is
at or above fair market value and shall have such other terms as the parties may
agree from time to time.  Manager shall not lend any funds to GROUP for such

any data or records necessary for Manager to perform its duties pursuant to this
Agreement.  GROUP and Manager shall comply with all applicable federal, state,
and local laws and regulations pertaining to the confidentiality of said medical
records.

          10.2.  All business records, information, software and systems of the
Manager relating to the provision of its services under this Agreement shall

the other, its officers, directors, agents, contractors, representatives and
employees, and each of its affiliates from and against any and all liability,
loss, damages, claims, causes of action, and expenses associated therewith
(including, without limitation, attorneys' fees) caused or asserted to have been
caused, directly or indirectly, by or as a result of any acts, errors or
omissions hereunder of the other, its contractors, shareholders, employees or
agents during the term hereof.  The provisions of this section shall survive the

all forms of contracts and other business documents or information of Manager,
whether currently or in the future developed or maintained by Manager and
including any and all deletions, additions, modifications and amendments thereto
and further including the amount of compensation to be paid to Manager for its

the exclusive, sole and absolute property of Manager.  Both parties acknowledge

upon Manager's prior written consent, GROUP shall not disclose to anyone, use,
copy, or take any such trade secrets or confidential and proprietary information
for GROUP's benefit or gain either during the term of this Agreement or at any
time after the termination hereof.  Upon any expiration or earlier termination
of this Agreement for any reason, GROUP shall not, without the prior written
consent of Manager, take or use any of Manager's Proprietary Materials, and
shall return to Manager all of Manager's Proprietary Materials in GROUP's
possession or control.

          12.2.  At all times during the term hereof and following the

otherwise, between Manager and any health care provider or supplier (including,
without limitation, any physician or osteopath), or any employee, independent

this Agreement, either party may commence arbitration by sending a written

                 15.12.3. There shall be one arbitrator.  If the parties shall

                 15.12.4. The parties shall share all costs of arbitration.

reduced to writing, signed by the arbitrator and mailed to each of the parties
and their legal counsel.

                 15.12.7. All decisions of the arbitrator shall be final,
binding and conclusive on the parties and shall constitute the only method of
resolving disputes or matters subject to arbitration pursuant to this Agreement.
The arbitrator or a court of appropriate jurisdiction may issue a writ of

such a decision in accordance with applicable law in any court having
jurisdiction thereof.

                 15.12.8. Notwithstanding the foregoing, because time is of the
essence of this Agreement, the parties specifically reserve the right to seek a
judicial temporary restraining order, preliminary injunction, or other similar
short term equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or
dissolve such court order.

reason of any alleged breach of this Agreement or of any provision hereof, or
for a declaration of rights hereunder (including, without limitation,
arbitration), the prevailing party in any such action or proceeding shall be
entitled to receive from the other party all costs and expenses, including

execute and deliver such further documentation as may reasonably be required in
order to give effect to the transactions contemplated by this Management
Services Agreement and the intentions of the parties hereto.

          15.15. RIGHTS CUMULATIVE.  The various rights and remedies herein
granted to Manager or GROUP shall be cumulative and in addition to any other
rights Manager or GROUP, respectively, may be entitled to under law.  The
exercise of one or more rights or remedies shall not impair the right of Manager
or GROUP to exercise any other right or remedy, at law or equity.

1395x (V)(1)(I) of Title 42 of the United States Code, with respect to any
services furnished under the terms of this Agreement if the value or cost of

corporation ("Guarantor"), in favor of Karanyan Arulanantham, M.D. ("Guarantied
Party") with reference to the following facts:

                                  R E C I T A L S

     A.   Prospect Medical Group, Inc., a California professional corporation
("Purchaser"), Guarantied Party, and certain others have entered into the Stock
Purchase Agreement in which certain financial accommodations were granted to
Purchaser by Guarantied Party.


<PAGE>

     B.   Guarantor is materially interested in the financial success of
Purchaser, agrees that the Stock Purchase Agreement is in Purchaser's best
interests, and acknowledges that the execution and delivery of this Guaranty
formed a material part of the consideration to Guarantied Party to induce
Guarantied Party to enter into the Stock Purchase Agreement.

                                 A G R E E M E N T

     NOW, THEREFORE, in consideration of the foregoing, Guarantor hereby agrees,
in favor of Guarantied Party, as follows:

     1.   DEFINITIONS AND CONSTRUCTION.

          (a)  DEFINITIONS.  The following terms, as used in this Guaranty,
shall have the following meanings:

               "Bankruptcy Code" shall mean The Bankruptcy Reform Act of 1978
(11 U.S.C. Sections 101-1330), as amended or supplemented from time to time, and
any successor statute, and any and all rules issued or promulgated in connection
therewith.

               "Guarantied Obligations" shall mean the due and punctual payment
of the principal of, and interest (including, any and all interest which, but
for the application of the provisions of the Bankruptcy Code, would have accrued
on such amounts) on, and premium, if any, on the Subordinated Note.

               "Guarantied Party" shall have the meaning set forth in the
preamble of this Guaranty.

               "Guarantor" shall have the meaning set forth in the preamble to
this Guaranty.

               "Guaranty" shall have the meaning set forth in the preamble to
this document.

               "Subordinated Note" shall mean the Contingent Promissory Note of
even date herewith, in the amount of $1,125,000, issued by Purchaser to
Guarantied Party pursuant to the terms of the Stock Purchase Agreement.

          (b)  CONSTRUCTION.  Unless the context of this Guaranty clearly
requires otherwise, references to the plural include the singular, references to
the singular include the plural, the part includes the whole, the terms
"include" and "including" are not limiting, and the term "or" has the inclusive
meaning represented by the phrase "and/or." The words "hereof," "herein,"
"hereby," "hereunder," and other similar terms refer to this Guaranty as a whole
and not to any particular provision of this Guaranty.  Any reference in this
Guaranty to any of the following documents includes any and all alterations,
amendments, extensions, modifications,


                                          2
<PAGE>

renewals, or supplements thereto or thereof, as applicable:  this Guaranty and
the Subordinated Note.  Neither this Guaranty nor any uncertainty or ambiguity
herein shall be construed or resolved against the Guarantied Party or Guarantor,
whether under any rule of construction or otherwise.  On the contrary, this
Guaranty has been reviewed by Guarantor, Guarantied Party, and their respective
counsel, and shall be construed and interpreted according to the ordinary
meaning of the words used so as to fairly accomplish the purposes and intentions
of Guarantied Party and Guarantor.

     2.   GUARANTEED OBLIGATIONS.  Guarantor hereby irrevocably and
unconditionally guarantees to Guarantied Party, as and for Guarantor's own debt,
until final and indefeasible payment thereof has been made, (a) payment of the
Guaranteed Obligations, in each case when and as the same shall become due and
payable, whether at maturity, pursuant to a mandatory prepayment requirement, by
acceleration, or otherwise; it being the intent of Guarantor that the guaranty
set forth herein shall be a guaranty of payment and not a guaranty of
collection, and (b) the punctual and faithful performance, keeping, observance,
and fulfillment by Purchaser of all of the agreements, conditions, covenants,
and obligations of Purchaser contained in the Subordinated Note and the Security
Agreement referred to in Section 20.

     3.   OMITTED.

     4.   PERFORMANCE UNDER THIS GUARANTY.  In the event that Purchaser fails to
make any payment of any Guaranteed Obligations on or before the due date
thereof, or if Purchaser shall fail to perform, keep, observe, or fulfill any
other obligation referred to in clause (b) of Section 2 hereof in the manner
provided in the Subordinated Note, Guarantor immediately shall cause such
payment to be made or each of such obligations to be performed, kept, observed,
or fulfilled.


                                          3
<PAGE>

     5.   PRIMARY OBLIGATIONS.  This Guaranty is a primary and original
obligation of Guarantor, is not merely the creation of a surety relationship,
and is an absolute, unconditional, and continuing guaranty of payment and
performance which shall remain in full force and effect without respect to
future changes in conditions, including any change of law or any invalidity or
irregularity with respect to the Subordinated Note.  Guarantor agrees that
Guarantor is directly, jointly and severally liable, with any other guarantor of
the Guaranteed Obligations, to Guarantied Party, to the extent set forth in
Section 2 hereof, that the obligations of Guarantor hereunder are independent of
the obligations of Purchaser or any other guarantor, and that a separate action
may be brought against Guarantor whether such action is brought against
Purchaser or any other guarantor or whether Purchaser or any such other
guarantor is joined in such action.  Guarantor agrees that Guarantor's liability
hereunder shall be immediate and shall not be contingent upon the exercise or
enforcement by Guarantied Party of whatever remedies it may have against
Purchaser or any other guarantor, or the enforcement of any lien or realization
upon any security Guarantied Party may at any time possess.  Guarantor agrees
that any release which may be given by Guarantied Party to Purchaser or any
other guarantor shall not release Guarantor.  Guarantor consents and agrees that
Guarantied Party shall be under no obligation to marshal any assets of Purchaser
or any other guarantor in favor of Guarantor, or against or in payment of any or
all of the Guaranteed Obligations.

     6.   WAIVERS.

          (a)  Guarantor absolutely, unconditionally, knowingly, and expressly
waives:

               (i)    (A) notice of acceptance hereof; (B) notice of the
creation or existence of any Guaranteed Obligations; (C) notice of the amount of
the Guaranteed Obligations, subject, however, to Guarantor's right to make
inquiry of Guarantied Party to ascertain the amount of the Guaranteed
Obligations at any reasonable time; (D) notice of any adverse change in the
financial condition of Purchaser or of any other fact that might increase
Guarantor's risk hereunder; (E) notice of presentment for payment, demand,
protest, and notice thereof as to the subordinated Note or any other
instruments; (F) notice of any unmatured event of default or Event of Default
under the Subordinated Note; and (G) all other notices (except if such notice is
specifically required to be given to Guarantor hereunder or under this Guaranty)
and demands to which Guarantor might otherwise be entitled.

               (ii)   its right, under Sections 2845 or 2850 of the California
Civil Code, or otherwise, to require Guarantied Party to institute suit against,
or to exhaust any rights and remedies which Guarantied Party has or may have
against, Purchaser or any third party, or against any collateral for the
Guaranteed Obligations provided by Purchaser or any third party.  In this
regard, Guarantor agrees that Guarantor is bound to the payment of all
Guaranteed Obligations, whether now existing or hereafter accruing, as fully as
if such Guaranteed Obligations were directly owing to Guarantied Party by
Guarantor.  Guarantor further waives any defense arising by reason of any
disability or other defense (other than the defense that the Guaranteed
Obligations shall have been fully and finally performed and indefeasibly paid)
of Purchaser or by reason of the cessation from any cause whatsoever of the
liability of Purchaser in respect thereof.


                                          4
<PAGE>

               (iii)  (A) any rights to assert against Guarantied Party any
defense (legal or equitable), set-off, counterclaim, or claim which Guarantor
may now or at any time hereafter have against Purchaser or any other party
liable to Guarantied Party; (B) any defense, set-off, counterclaim, or claim, of
any kind or nature, arising directly or indirectly from the present or future
lack of perfection, sufficiency, validity, or enforceability of the Guaranteed
Obligations or any security therefor; (C) any defense Guarantor has to
performance hereunder, and any right Guarantor has to be exonerated, provided by
Sections 2819, 2822, or 2825 of the California Civil Code, or otherwise, arising
by reason of: the impairment or suspension of Guarantied Party's rights or
remedies against Purchaser; the alteration by Guarantied Party of the Guaranteed
Obligations; any discharge of Purchaser's obligations to Guarantied Party by
operation of law as a result of Guarantied Party's intervention or omission; or
the acceptance by Guarantied Party of anything in partial satisfaction of the
Guaranteed Obligations; (D) the benefit of any statute of limitations affecting
Guarantor's liability hereunder or the enforcement thereof, and any act which
shall defer or delay the operation of any statute of limitations applicable to
the Guaranteed Obligations shall similarly operate to defer or delay the
operation of such statute of limitations applicable to Guarantor's liability
hereunder.

          (b)  Guarantor absolutely, unconditionally, knowingly, and expressly
waives any defense arising by reason of or deriving from (i) any claim or
defense based upon an election of remedies by Guarantied Party including any
defense based upon an election of remedies by Guarantied Party under the
provisions of Sections 580a, 580b, 580d, and 726 of the California Code of Civil
Procedure or any similar law of California or any other jurisdiction; or (ii)
any election by Guarantied Party under Bankruptcy Code Section 1111(b) to limit
the amount of, or any collateral securing, its claim against Purchaser.
Pursuant to Section 2856 of the California Civil Code:

               Guarantor waives all rights and defenses arising out of an
election of remedies by the creditor, even though that election of remedies,
such as a nonjudicial foreclosure with respect to security for a guaranteed
obligation, has destroyed Guarantor's rights of subrogation and reimbursement
against Purchaser by the operation of Section 580(d) of the California Code of
Civil Procedure or otherwise.

               Guarantor waives all rights and defenses that Guarantor may have
because Purchaser's obligations are secured by real property.  This means, among
other things:

               (i)    Guarantied Party may collect from Guarantor without first
foreclosing on any real or personal property collateral pledged by Purchaser.

               (ii)   If Guarantied Party forecloses on any real property
collateral pledged by Purchaser:

                      (A)     The amount of the Guaranteed Obligations may be
reduced only by the price for which that collateral is sold at the foreclosure
sale, even if the collateral is worth more than the sale price.


                                          5
<PAGE>

                      (B)     Guarantied Party may collect from Guarantor even
if Guarantied Party, by foreclosing on the real property collateral, has
destroyed any right Guarantor may have to collect from Purchaser.

               This is an unconditional and irrevocable waiver of any rights and
defenses Guarantor may have because Purchaser's Obligations are secured by real
property.  These rights and defenses include, but are not limited to, any rights
or defenses based upon Section 580a, 580b, 580d, or 726 of the California Code
of Civil Procedure.

If any of the Guaranteed Obligations at any time are secured by a mortgage or
deed of trust upon real property, Guarantied Party may elect, in its sole
discretion, upon a default with respect to the Guaranteed Obligations, to
foreclose such mortgage or deed of trust judicially or nonjudicially in any
manner permitted by law, before or after enforcing the Subordinated Note,
without diminishing or affecting the liability of Guarantor hereunder except to
the extent the Guaranteed Obligations are repaid with the proceeds of such
foreclosure.  Guarantor understands that (a) by virtue of the operation of
California's antideficiency law applicable to nonjudicial foreclosures, an
election by Guarantied Party nonjudicially to foreclose such a mortgage or deed
of trust probably would have the effect of impairing or destroying rights of
subrogation, reimbursement, contribution, or indemnity of Guarantor against
Purchaser or other guarantors or sureties, and (b) absent the waiver given by
Guarantor, such an election would prevent Guarantied Party from enforcing the
Subordinated Note against Guarantor.  Understanding the foregoing, and
understanding that Guarantor is hereby relinquishing a defense to the
enforceability of the Subordinated Note, Guarantor hereby waives any right to
assert against Guarantied Party any defense to the enforcement of the
Subordinated Note, whether denominated "estoppel" or otherwise, based on or
arising from an election by Guarantied Party nonjudicially to foreclose any such
mortgage or deed of trust.  Guarantor understands that the effect of the
foregoing waiver may be that Guarantor may have liability hereunder for amounts
with respect to which Guarantor may be left without rights of subrogation,
reimbursement, contribution, or indemnity against Purchaser or other guarantors
or sureties.  Guarantor also agrees that the "fair market value" provisions of
Section 580a of the California Code of Civil Procedure shall have no
applicability with respect to the determination of Guarantor's liability under
the Subordinated Note.

          (c)  Guarantor hereby absolutely, unconditionally, knowingly, and
expressly waives:  (i) any right of subrogation Guarantor has or may have as
against Purchaser with respect to the Guaranteed Obligations; (ii) any right to
proceed against Purchaser or any other person or entity, now, or hereafter, for
contribution, indemnity, reimbursement, or any other suretyship rights and
claims, whether direct or indirect, liquidated or contingent, whether arising
under express or implied contract or by operation of law, which Guarantor may
now have or hereafter have as against Purchaser with respect to the Guaranteed
Obligations; and (iii) any right to proceed or seek recourse against or with
respect to any property or asset of Purchaser.  Guarantor hereby agrees that, in
light of the waivers contained in this section, Guarantor shall not be deemed to
be a "creditor" (as that term is defined in the Bankruptcy Code or otherwise) of
Purchaser, whether for purposes of the application of Sections 547 or 550 of the
Bankruptcy Code or otherwise.


                                          6
<PAGE>

          (d)  WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER
PROVISION SET FORTH IN THIS GUARANTY, GUARANTOR HEREBY ABSOLUTELY, KNOWINGLY,
UNCONDITIONALLY, AND EXPRESSLY WAIVES AND AGREES NOT TO ASSERT ANY AND ALL
BENEFITS OR DEFENSES ARISING DIRECTLY OR INDIRECTLY UNDER ANY ONE OR MORE OF
CALIFORNIA CIVIL CODE SECTIONS 2799, 2808, 2809, 2810, 2815, 2819, 2820, 2821,
2822, 2825, 2839, 2845, 2848, 2849, AND 2850, CALIFORNIA CODE OF CIVIL PROCEDURE
SECTIONS 580a, 580b, 580c, 580d, AND 726, AND CHAPTER 2 OF TITLE 14 OF PART 4 OF
DIVISION 3 OF THE CALIFORNIA CIVIL CODE.

     7.   RELEASES.  Guarantor consents and agrees that, without notice to or by
Guarantor, and without affecting or impairing the obligations of Guarantor
hereunder, Guarantied Party may, by action or inaction:

          (a)  compromise, settle, extend the duration or the time for the
payment of, or discharge the performance of, or may refuse to or otherwise not
enforce this Guaranty, the Subordinated Note, or any part thereof, with respect
to Purchaser or any other Person;

          (b)  release Purchaser or any other person or grant other indulgences
to Purchaser or any other Person in respect thereof;

          (c)  amend or modify in any manner and at any time (or from time to
time) the Subordinated Note; or

          (d)  release or substitute any other guarantor, if any, of the
Guaranteed Obligations, or enforce, exchange, release, or waive any security for
the Guaranteed Obligations or any other guaranty of the Guaranteed Obligations,
or any portion thereof.

     8.   NO ELECTION.  Guarantied Party shall have all of the rights to seek
recourse against Guarantor to the fullest extent provided for herein, and no
election by Guarantied Party to proceed in one form of action or proceeding, or
against any party, or on any obligation, shall constitute a waiver of Guarantied
Party's right to proceed in any other form of action or proceeding or against
other parties unless Guarantied Party has expressly waived such right in
writing.  Specifically, but without limiting the generality of the foregoing, no
action or proceeding by Guarantied Party under any document or instrument
evidencing the Guaranteed Obligations shall serve to diminish the liability of
Guarantor under this Guaranty except to the extent that Guarantied Party finally
and unconditionally shall have realized indefeasible payment by such action or
proceeding.


                                          7
<PAGE>

     9.   INDEFEASIBLE PAYMENT.  The Guaranteed Obligations shall not be
considered indefeasibly paid for purposes of this Guaranty unless and until all
payments to Guarantied Party are no longer subject to any right on the part of
any person, including Purchaser, Purchaser as a debtor in possession, or any
trustee (whether appointed under the Bankruptcy Code or otherwise) of any of
Purchaser's assets, to invalidate or set aside such payments or to seek to
recoup the amount of such payments or any portion thereof, or to declare same to
be fraudulent or preferential.  Upon such full and final performance and
indefeasible payment of the Guaranteed Obligations, whether by Purchaser
pursuant to the Subordinated Note or by any other person, Guarantied Party shall
have no obligation whatsoever to transfer or assign its interests in the
Subordinated Note to Guarantor.  In the event that, for any reason, any portion
of such payments to Guarantied Party is set aside or restored, whether
voluntarily or involuntarily, after the making thereof, then the obligation
intended to be satisfied thereby shall be revived and continued in full force
and effect as if said payment or payments had not been made, and Guarantor shall
be liable for the full amount Guarantied Party is required to repay plus any and
all costs and expenses (including attorneys' fees and expenses and attorneys'
fees and expenses incurred pursuant to proceedings arising under the Bankruptcy
Code) paid by Guarantied Party in connection therewith.

     10.  FINANCIAL CONDITION OF PURCHASER.  Guarantor represents and warrants
to Guarantied Party that Guarantor is currently informed of the financial
condition of Purchaser and of all other circumstances which a diligent inquiry
would reveal and which bear upon the risk of nonpayment of the Guaranteed
Obligations.  Guarantor further represents and warrants to Guarantied Party that
Guarantor has read and understands the terms and conditions of the Subordinated
Note.  Guarantor hereby covenants that Guarantor will continue to keep informed
of Purchaser's financial condition, the financial condition of other guarantors,
if any, and of all other circumstances which bear upon the risk of nonpayment or
nonperformance of the Guaranteed Obligations.

     11.  SUBORDINATION.  Guarantor and Guarantied Party agree that,
notwithstanding the terms of this Guaranty, the payment of the Guarantied
Obligations and all other obligations of Guarantor hereunder is subordinated, to
the extent and in the manner set forth in the Subordination and Note
Cancellation Agreement, to the prior payment of all indebtedness and obligations
of Guarantor owing to Bank, as more particularly set forth in the Subordination
and Note Cancellation Agreement.  In the event that any conflict exists between
the terms of this Guaranty, any document executed in connection with the
delivery of this Guaranty and the terms of the Subordination and Note
Cancellation Agreement, the terms of the Subordination and Note Cancellation
Agreement shall govern and be controlling.

     12.  PAYMENTS; APPLICATION.  All payments to be made hereunder by Guarantor
shall be made in lawful money of the United States of America at the time of
payment, shall be made in immediately available funds, and shall be made without
deduction (whether for taxes or otherwise) or offset.  All payments made by
Guarantor hereunder shall be applied as follows: first, to all costs and
expenses (including attorneys' fees and expenses and attorneys' fees and
expenses incurred pursuant to proceedings arising under the Bankruptcy Code)
incurred by Guarantied Party in enforcing this Guaranty or in collecting the
Guaranteed Obligations; second,


                                          8
<PAGE>

to all accrued and unpaid interest, premium, if any, and fees owing to
Guarantied Party constituting Guaranteed Obligations; and third, to the balance
of the Guaranteed Obligations.

     13.  REPRESENTATIONS AND WARRANTIES.  Guarantor hereby represents and
warrants to Guarantied Party that:

          (a)  Guarantor is a corporation duly organized and existing under the
laws of Delaware and has the power and authority to own its own properties and
assets, and to transact the business in which it is engaged, and is properly
licensed, qualified to do business and in good standing in every jurisdiction
where the conduct of its business requires it to be so qualified.

          (b)  The execution, delivery and performance of this Guaranty are
within Guarantor's powers, are not in conflict with the terms of any charter,
bylaw, certificate of incorporation or other organization papers of Guarantor,
and do not result in a breach of or constitute a default under any contract,
obligation, indenture or other instrument to which Guarantor is a party or by
which Guarantor is bound or affected.  There is no law, rule or regulation, nor
is there any judgment, decree or order of any court or governmental authority
binding on Guarantor which would be contravened by the execution, delivery,
performance or enforcement of this Guaranty.

          (c)  Guarantor has taken all corporate action necessary to authorize
the execution and delivery of this Guaranty, and the consummation of the
transactions contemplated hereby and thereby.  Upon their execution and delivery
in accordance with their respective terms, this Guaranty will constitute legal,
valid and binding agreements and obligations of Guarantor enforceable against
Guarantor in accordance with its terms, except as enforceability may be limited
by Bankruptcy, insolvency, fraudulent conveyance, and similar laws and equitable
principles affecting the enforcement of creditors' rights generally.

          (d)  No approval, consent, exemption or other action by, or notice to
or filing with, any governmental authority is necessary in connection with the
execution, delivery, performance or enforcement of this Guaranty except as may
have been obtained by Guarantor and certified copies of which have been
delivered to Guarantied Party.

     14.  ATTORNEYS' FEES AND COSTS.  Guarantor agrees to pay, on demand, all
attorneys' fees (including attorneys' fees incurred pursuant to proceedings
arising under the Bankruptcy Code) and all other costs and expenses which may be
incurred by Guarantied Party in the enforcement of this Guaranty or in any way
arising out of, or consequential to the protection, assertion, or enforcement of
the Guaranteed Obligations (or any security therefor), whether or not suit is
brought.

     15.  NOTICES. Unless otherwise specifically provided herein, any notice or
other communication herein required or permitted to be given shall be in writing
and may be personally served, sent by telefacsimile, telexed, or sent by courier
service or United States mail and shall be deemed to have been given when
delivered in person or by courier service, on the next business day after
receipt of a telefacsimile or telex, or four business days after deposit in

     16.  CUMULATIVE REMEDIES.  No remedy under this Guaranty or the
Subordinated Note is intended to be exclusive of any other remedy, but each and
every remedy shall be cumulative and in addition to any and every other remedy
given hereunder or under the Subordinated Note, and those provided by law or in
equity.  No delay or omission by Guarantied Party to exercise any right under
this Guaranty shall impair any such right nor be construed to be a waiver
thereof.  No failure on the part of Guarantied Party to exercise, and no delay
in exercising, any right hereunder shall operate as a waiver thereof; nor shall
any single or partial exercise of any right hereunder preclude any other or
further exercise thereof or the exercise of any other right.

     17.  BOOKS AND RECORDS.  Guarantor agrees Guarantied Party's books and
records showing the account between Guarantied Party and Purchaser shall be
admissible in any action or proceeding and shall be binding upon Guarantor for
the purpose of establishing the items therein set forth and shall constitute
prima facie proof thereof.

     18.  SEVERABILITY OF PROVISIONS.  If any provision of this Guaranty is for
any reason held to be invalid, illegal or unenforceable in any respect, that
provision shall not affect the validity, legality or enforceability of any other
provision of this Guaranty.


                                          10

     19.  ENTIRE AGREEMENT, AMENDMENTS AND WAIVERS.  This Guaranty constitutes
the entire agreement between Guarantor and Guarantied Party pertaining to the
subject matter contained herein.  Any provision of this Guaranty may be amended
or waived if, but only if, such amendment or waiver is in writing and is signed
by the party asserted to be bound thereby, and then such amendment or waiver
shall be effective only in the specific instance and specific purpose for which
given.

     20.  SECURITY.  This Guaranty is secured by that certain Security
Agreement, as of even date herewith, between Guarantor and Guarantied Party, as
the same may be amended from time to time.

     21.  SUCCESSORS AND ASSIGNS.  This Guaranty shall bind the successors and
assigns of Guarantor, and shall inure to the benefit of the respective
successors and assigns of Guarantied Party; PROVIDED, HOWEVER, Guarantor may not
assign this Guaranty or delegate any of his duties hereunder without Guarantied
Party's prior written consent and any such prohibited assignment shall be
absolutely null and void.  In the event of any assignment or other transfer of
rights by a Guarantied Party, the rights and benefits herein conferred upon such
Guarantied Party shall automatically extend to and be vested in such assignee or
other transferee.

     22.  GOVERNING LAW.  This Guaranty shall be deemed to have been made in the
State of California and the validity, construction, interpretation, and
enforcement hereof, and the rights of the parties hereto, shall be determined
under, governed by, and construed in accordance with the internal laws of the
State of California, without regard to principles of conflicts of law.

     23.  ARBITRATION.  The parties firmly desire to resolve all disputes
arising hereunder without resort to litigation in order to protect their
respective business reputations and the confidential nature of certain aspects
of their relationship.  Accordingly, any controversy or claim arising out of or
relating to this Guaranty, or the breach thereof, shall be settled by
arbitration as set forth below.

          (a)  All disputes which in any manner arise out of or relate to this
Guaranty or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 23.  Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

          (b)  The parties stipulate to arbitration before a single, mutually
agreed upon arbitrator sitting on the Los Angeles, California Judicial
Arbitration Mediation Services (JAMS) panel.  In the event that the parties are
unable to agree upon the person chosen as arbitrator within 30 days of the
demand for arbitration, the arbitrator shall be selected in the sole discretion
of the JAMS administrator.  The arbitrator shall be a member of the California
bar.


                                          11
<PAGE>

          (c)  The parties shall share all costs of arbitration.  The prevailing
party shall be entitled to reimbursement by the other party of such party's
attorneys' fees and costs and any arbitration fees and expenses incurred in
connection with the arbitration hereunder.

          (d)  The substantive law of the State of California shall be applied
by the arbitrator.  All proceedings in arbitration shall be in accordance with
the California Code of Civil Procedure, as amended, and the parties shall have
the right to legal discovery in any matter submitted to arbitration in
satisfaction of California Code of Civil Procedure Section 1283.05, as permitted
by California Code of Civil Procedure Section 1283.1(b).

          (e)  Arbitration shall take place in Los Angeles, California unless
the parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable thereunder, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

          (f)  All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Guaranty.  The
arbitrator or a court of appropriate jurisdiction may issue a write of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

          (g)  Notwithstanding the foregoing, because time is of the essence of
this Guaranty, the parties specifically reserve the right to a judicial
temporary restraining order, preliminary injunction, or other similar equitable
relief.

          (h)  The decision and award of the arbitrator shall be kept
confidential by the parties to the greatest extent possible.  No disclosure of
such decision or award shall be made by the parties except as required by law or
as necessary or appropriate to effect the enforcement thereof.

          (i)  Should either party institute any action or procedure to enforce
this Guaranty or any provision hereof, or for damages by reason of any alleged
breach of this Guaranty or of any provision hereof, or for a declaration of
rights hereunder (including, without limitation, arbitration), the prevailing
party in any such action or proceeding shall be entitled to


                                          12
<PAGE>

receive from the other party all costs and expenses, including, without
limitation, reasonable attorneys' fees, incurred by the prevailing party in
connection with such action or proceeding.

     IN WITNESS WHEREOF, Guarantor has executed and delivered this Guaranty as
of the date set forth in the first paragraph hereof.

     This SUBORDINATE GUARANTY (this "GUARANTY"), dated as of  September 25,
1997, is executed and delivered by Prospect Medical Holdings, Inc., a Delaware
corporation ("Guarantor"), in favor of Sinnadurai E. Moorthy, M.D. ("Guarantied

                                  R E C I T A L S

     A.   Prospect Medical Group, Inc., a California professional corporation
("Purchaser"), Guarantied Party, and certain others have entered into the Stock
Purchase Agreement in which certain financial accommodations were granted to

<PAGE>

     B.   Guarantor is materially interested in the financial success of
Purchaser, agrees that the Stock Purchase Agreement is in Purchaser's best
interests, and acknowledges that the execution and delivery of this Guaranty
formed a material part of the consideration to Guarantied Party to induce
Guarantied Party to enter into the Stock Purchase Agreement.

                                 A G R E E M E N T

     NOW, THEREFORE, in consideration of the foregoing, Guarantor hereby agrees,
in favor of Guarantied Party, as follows:

     1.   DEFINITIONS AND CONSTRUCTION.

          (a)  DEFINITIONS.  The following terms, as used in this Guaranty,
shall have the following meanings:

               "Bankruptcy Code" shall mean The Bankruptcy Reform Act of 1978
(11 U.S.C. Sections 101-1330), as amended or supplemented from time to time, and
any successor statute, and any and all rules issued or promulgated in connection
therewith.

               "Guarantied Obligations" shall mean the due and punctual payment
of the principal of, and interest (including, any and all interest which, but
for the application of the provisions of the Bankruptcy Code, would have accrued
on such amounts) on, and premium, if any, on the Subordinated Note.

               "Guarantied Party" shall have the meaning set forth in the
preamble of this Guaranty.

               "Guarantor" shall have the meaning set forth in the preamble to
this Guaranty.

               "Guaranty" shall have the meaning set forth in the preamble to
this document.

               "Subordinated Note" shall mean the Contingent Promissory Note of
even date herewith, in the amount of $1,125,000, issued by Purchaser to
Guarantied Party pursuant to the terms of the Stock Purchase Agreement.

          (b)  CONSTRUCTION.  Unless the context of this Guaranty clearly
requires otherwise, references to the plural include the singular, references to
the singular include the plural, the part includes the whole, the terms
"include" and "including" are not limiting, and the term "or" has the inclusive
meaning represented by the phrase "and/or." The words "hereof," "herein,"
"hereby," "hereunder," and other similar terms refer to this Guaranty as a whole
and not to any particular provision of this Guaranty.  Any reference in this
Guaranty to any of the following documents includes any and all alterations,
amendments, extensions, modifications,


                                          2
<PAGE>

renewals, or supplements thereto or thereof, as applicable:  this Guaranty and
the Subordinated Note.  Neither this Guaranty nor any uncertainty or ambiguity
herein shall be construed or resolved against the Guarantied Party or Guarantor,
whether under any rule of construction or otherwise.  On the contrary, this
Guaranty has been reviewed by Guarantor, Guarantied Party, and their respective
counsel, and shall be construed and interpreted according to the ordinary
meaning of the words used so as to fairly accomplish the purposes and intentions
of Guarantied Party and Guarantor.

     2.   GUARANTEED OBLIGATIONS.  Guarantor hereby irrevocably and
unconditionally guarantees to Guarantied Party, as and for Guarantor's own debt,
until final and indefeasible payment thereof has been made, (a) payment of the
Guaranteed Obligations, in each case when and as the same shall become due and
payable, whether at maturity, pursuant to a mandatory prepayment requirement, by
acceleration, or otherwise; it being the intent of Guarantor that the guaranty
set forth herein shall be a guaranty of payment and not a guaranty of
collection, and (b) the punctual and faithful performance, keeping, observance,
and fulfillment by Purchaser of all of the agreements, conditions, covenants,
and obligations of Purchaser contained in the Subordinated Note and the Security
Agreement referred to in Section 20.

     3.   PERFORMANCE UNDER THIS GUARANTY.  In the event that Purchaser fails to
make any payment of any Guaranteed Obligations on or before the due date
thereof, or if Purchaser shall fail to perform, keep, observe, or fulfill any
other obligation referred to in clause (b) of Section 2 hereof in the manner
provided in the Subordinated Note, Guarantor immediately shall cause such
payment to be made or each of such obligations to be performed, kept, observed,
or fulfilled.


                                          3
<PAGE>

     4.   PRIMARY OBLIGATIONS.  This Guaranty is a primary and original
obligation of Guarantor, is not merely the creation of a surety relationship,
and is an absolute, unconditional, and continuing guaranty of payment and
performance which shall remain in full force and effect without respect to
future changes in conditions, including any change of law or any invalidity or
irregularity with respect to the Subordinated Note.  Guarantor agrees that
Guarantor is directly, jointly and severally liable, with any other guarantor of
the Guaranteed Obligations, to Guarantied Party, to the extent set forth in
Section 2 hereof, that the obligations of Guarantor hereunder are independent of
the obligations of Purchaser or any other guarantor, and that a separate action
may be brought against Guarantor whether such action is brought against
Purchaser or any other guarantor or whether Purchaser or any such other
guarantor is joined in such action.  Guarantor agrees that Guarantor's liability
hereunder shall be immediate and shall not be contingent upon the exercise or
enforcement by Guarantied Party of whatever remedies it may have against
Purchaser or any other guarantor, or the enforcement of any lien or realization
upon any security Guarantied Party may at any time possess.  Guarantor agrees
that any release which may be given by Guarantied Party to Purchaser or any
other guarantor shall not release Guarantor.  Guarantor consents and agrees that
Guarantied Party shall be under no obligation to marshal any assets of Purchaser
or any other guarantor in favor of Guarantor, or against or in payment of any or
all of the Guaranteed Obligations.

     5.   WAIVERS.

          (a)  Guarantor absolutely, unconditionally, knowingly, and expressly
waives:

               (i)       (A) notice of acceptance hereof; (B) notice of the
creation or existence of any Guaranteed Obligations; (C) notice of the amount of
the Guaranteed Obligations, subject, however, to Guarantor's right to make
inquiry of Guarantied Party to ascertain the amount of the Guaranteed
Obligations at any reasonable time; (D) notice of any adverse change in the
financial condition of Purchaser or of any other fact that might increase
Guarantor's risk hereunder; (E) notice of presentment for payment, demand,
protest, and notice thereof as to the subordinated Note or any other
instruments; (F) notice of any unmatured event of default or Event of Default
under the Subordinated Note; and (G) all other notices (except if such notice is
specifically required to be given to Guarantor hereunder or under this Guaranty)
and demands to which Guarantor might otherwise be entitled.

               (ii)      its right, under Sections 2845 or 2850 of the
California Civil Code, or otherwise, to require Guarantied Party to institute
suit against, or to exhaust any rights and remedies which Guarantied Party has
or may have against, Purchaser or any third party, or against any collateral for
the Guaranteed Obligations provided by Purchaser or any third party.  In this
regard, Guarantor agrees that Guarantor is bound to the payment of all
Guaranteed Obligations, whether now existing or hereafter accruing, as fully as
if such Guaranteed Obligations were directly owing to Guarantied Party by
Guarantor.  Guarantor further waives any defense arising by reason of any
disability or other defense (other than the defense that the Guaranteed
Obligations shall have been fully and finally performed and indefeasibly paid)
of Purchaser or by reason of the cessation from any cause whatsoever of the
liability of Purchaser in respect thereof.


                                          4
<PAGE>

               (iii)     (A) any rights to assert against Guarantied Party any
defense (legal or equitable), set-off, counterclaim, or claim which Guarantor
may now or at any time hereafter have against Purchaser or any other party
liable to Guarantied Party; (B) any defense, set-off, counterclaim, or claim, of
any kind or nature, arising directly or indirectly from the present or future
lack of perfection, sufficiency, validity, or enforceability of the Guaranteed
Obligations or any security therefor; (C) any defense Guarantor has to
performance hereunder, and any right Guarantor has to be exonerated, provided by
Sections 2819, 2822, or 2825 of the California Civil Code, or otherwise, arising
by reason of: the impairment or suspension of Guarantied Party's rights or
remedies against Purchaser; the alteration by Guarantied Party of the Guaranteed
Obligations; any discharge of Purchaser's obligations to Guarantied Party by
operation of law as a result of Guarantied Party's intervention or omission; or
the acceptance by Guarantied Party of anything in partial satisfaction of the
Guaranteed Obligations; (D) the benefit of any statute of limitations affecting
Guarantor's liability hereunder or the enforcement thereof, and any act which
shall defer or delay the operation of any statute of limitations applicable to
the Guaranteed Obligations shall similarly operate to defer or delay the
operation of such statute of limitations applicable to Guarantor's liability
hereunder.

          (b)  Guarantor absolutely, unconditionally, knowingly, and expressly
waives any defense arising by reason of or deriving from (i) any claim or
defense based upon an election of remedies by Guarantied Party including any
defense based upon an election of remedies by Guarantied Party under the
provisions of Sections 580a, 580b, 580d, and 726 of the California Code of Civil
Procedure or any similar law of California or any other jurisdiction; or (ii)
any election by Guarantied Party under Bankruptcy Code Section 1111(b) to limit
the amount of, or any collateral securing, its claim against Purchaser.
Pursuant to Section 2856 of the California Civil Code:

               Guarantor waives all rights and defenses arising out of an
election of remedies by the creditor, even though that election of remedies,
such as a nonjudicial foreclosure with respect to security for a guaranteed
obligation, has destroyed Guarantor's rights of subrogation and reimbursement
against Purchaser by the operation of Section 580(d) of the California Code of
Civil Procedure or otherwise.

               Guarantor waives all rights and defenses that Guarantor may have
because Purchaser's obligations are secured by real property.  This means, among
other things:

               (i)       Guarantied Party may collect from Guarantor without
first foreclosing on any real or personal property collateral pledged by
Purchaser.

               (ii)      If Guarantied Party forecloses on any real property
collateral pledged by Purchaser:

                    (A)  The amount of the Guaranteed Obligations may be reduced
only by the price for which that collateral is sold at the foreclosure sale,
even if the collateral is worth more than the sale price.


                                          5
<PAGE>

                    (B)  Guarantied Party may collect from Guarantor even if
Guarantied Party, by foreclosing on the real property collateral, has destroyed
any right Guarantor may have to collect from Purchaser.

               This is an unconditional and irrevocable waiver of any rights and
defenses Guarantor may have because Purchaser's Obligations are secured by real
property.  These rights and defenses include, but are not limited to, any rights
or defenses based upon Section 580a, 580b, 580d, or 726 of the California Code
of Civil Procedure.

If any of the Guaranteed Obligations at any time are secured by a mortgage or
deed of trust upon real property, Guarantied Party may elect, in its sole
discretion, upon a default with respect to the Guaranteed Obligations, to
foreclose such mortgage or deed of trust judicially or nonjudicially in any
manner permitted by law, before or after enforcing the Subordinated Note,
without diminishing or affecting the liability of Guarantor hereunder except to
the extent the Guaranteed Obligations are repaid with the proceeds of such
foreclosure.  Guarantor understands that (a) by virtue of the operation of
California's antideficiency law applicable to nonjudicial foreclosures, an
election by Guarantied Party nonjudicially to foreclose such a mortgage or deed
of trust probably would have the effect of impairing or destroying rights of
subrogation, reimbursement, contribution, or indemnity of Guarantor against
Purchaser or other guarantors or sureties, and (b) absent the waiver given by
Guarantor, such an election would prevent Guarantied Party from enforcing the
Subordinated Note against Guarantor.  Understanding the foregoing, and
understanding that Guarantor is hereby relinquishing a defense to the
enforceability of the Subordinated Note, Guarantor hereby waives any right to
assert against Guarantied Party any defense to the enforcement of the
Subordinated Note, whether denominated "estoppel" or otherwise, based on or
arising from an election by Guarantied Party nonjudicially to foreclose any such
mortgage or deed of trust.  Guarantor understands that the effect of the
foregoing waiver may be that Guarantor may have liability hereunder for amounts
with respect to which Guarantor may be left without rights of subrogation,
reimbursement, contribution, or indemnity against Purchaser or other guarantors
or sureties.  Guarantor also agrees that the "fair market value" provisions of
Section 580a of the California Code of Civil Procedure shall have no
applicability with respect to the determination of Guarantor's liability under
the Subordinated Note.

          (c)  Guarantor hereby absolutely, unconditionally, knowingly, and
expressly waives:  (i) any right of subrogation Guarantor has or may have as
against Purchaser with respect to the Guaranteed Obligations; (ii) any right to
proceed against Purchaser or any other person or entity, now, or hereafter, for
contribution, indemnity, reimbursement, or any other suretyship rights and
claims, whether direct or indirect, liquidated or contingent, whether arising
under express or implied contract or by operation of law, which Guarantor may
now have or hereafter have as against Purchaser with respect to the Guaranteed
Obligations; and (iii) any right to proceed or seek recourse against or with
respect to any property or asset of Purchaser.  Guarantor hereby agrees that, in
light of the waivers contained in this section, Guarantor shall not be deemed to
be a "creditor" (as that term is defined in the Bankruptcy Code or otherwise) of
Purchaser, whether for purposes of the application of Sections 547 or 550 of the
Bankruptcy Code or otherwise.


                                          6
<PAGE>

          (d)  WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER
PROVISION SET FORTH IN THIS GUARANTY, GUARANTOR HEREBY ABSOLUTELY, KNOWINGLY,
UNCONDITIONALLY, AND EXPRESSLY WAIVES AND AGREES NOT TO ASSERT ANY AND ALL
BENEFITS OR DEFENSES ARISING DIRECTLY OR INDIRECTLY UNDER ANY ONE OR MORE OF
CALIFORNIA CIVIL CODE SECTIONS 2799, 2808, 2809, 2810, 2815, 2819, 2820, 2821,
2822, 2825, 2839, 2845, 2848, 2849, AND 2850, CALIFORNIA CODE OF CIVIL PROCEDURE
SECTIONS 580a, 580b, 580c, 580d, AND 726, AND CHAPTER 2 OF TITLE 14 OF PART 4 OF
DIVISION 3 OF THE CALIFORNIA CIVIL CODE.

     6.   RELEASES.  Guarantor consents and agrees that, without notice to or by
Guarantor, and without affecting or impairing the obligations of Guarantor
hereunder, Guarantied Party may, by action or inaction:

          (a)  compromise, settle, extend the duration or the time for the
payment of, or discharge the performance of, or may refuse to or otherwise not
enforce this Guaranty, the Subordinated Note, or any part thereof, with respect
to Purchaser or any other Person;

          (b)  release Purchaser or any other person or grant other indulgences
to Purchaser or any other Person in respect thereof;

          (c)  amend or modify in any manner and at any time (or from time to
time) the Subordinated Note; or

          (d)  release or substitute any other guarantor, if any, of the
Guaranteed Obligations, or enforce, exchange, release, or waive any security for
the Guaranteed Obligations or any other guaranty of the Guaranteed Obligations,
or any portion thereof.

     7.   NO ELECTION.  Guarantied Party shall have all of the rights to seek
recourse against Guarantor to the fullest extent provided for herein, and no
election by Guarantied Party to proceed in one form of action or proceeding, or
against any party, or on any obligation, shall constitute a waiver of Guarantied
Party's right to proceed in any other form of action or proceeding or against
other parties unless Guarantied Party has expressly waived such right in
writing.  Specifically, but without limiting the generality of the foregoing, no
action or proceeding by Guarantied Party under any document or instrument
evidencing the Guaranteed Obligations shall serve to diminish the liability of
Guarantor under this Guaranty except to the extent that Guarantied Party finally
and unconditionally shall have realized indefeasible payment by such action or
proceeding.

     8.   INDEFEASIBLE PAYMENT.  The Guaranteed Obligations shall not be
considered indefeasibly paid for purposes of this Guaranty unless and until all
payments to Guarantied Party are no longer subject to any right on the part of
any person, including Purchaser, Purchaser as a debtor in possession, or any
trustee (whether appointed under the Bankruptcy Code or otherwise) of any of
Purchaser's assets, to invalidate or set aside such payments or to seek to
recoup the amount of such payments or any portion thereof, or to declare same to
be fraudulent or preferential.  Upon such full and final performance and
indefeasible payment of the Guaranteed Obligations, whether by Purchaser
pursuant to the Subordinated Note or by any other person, Guarantied Party shall
have no obligation whatsoever to transfer or assign its interests in the
Subordinated Note to Guarantor.  In the event that, for any reason, any portion
of such payments to Guarantied Party is set aside or restored, whether
voluntarily or involuntarily, after the making thereof, then the obligation
intended to be satisfied thereby shall be revived and continued in full force
and effect as if said payment or payments had not been made, and Guarantor shall
be liable for the full amount Guarantied Party is required to repay plus any and
all costs and expenses (including attorneys' fees and expenses and attorneys'
fees and expenses incurred pursuant to proceedings arising under the Bankruptcy
Code) paid by Guarantied Party in connection therewith.

     9.   FINANCIAL CONDITION OF PURCHASER.  Guarantor represents and warrants
to Guarantied Party that Guarantor is currently informed of the financial
condition of Purchaser and of all other circumstances which a diligent inquiry
would reveal and which bear upon the risk of nonpayment of the Guaranteed
Obligations.  Guarantor further represents and warrants to Guarantied Party that
Guarantor has read and understands the terms and conditions of the Subordinated
Note.  Guarantor hereby covenants that Guarantor will continue to keep informed
of Purchaser's financial condition, the financial condition of other guarantors,
if any, and of all other circumstances which bear upon the risk of nonpayment or
nonperformance of the Guaranteed Obligations.

     10.  SUBORDINATION.  Guarantor and Guarantied Party agree that,
notwithstanding the terms of this Guaranty, the payment of the Guaranteed
Obligations and all other obligations of Guarantor hereunder is subordinated, to
the extent and in the manner set forth in the Subordination and Note
Cancellation Agreement, to the prior payment of all indebtedness and obligations
of Guarantor owing to Bank, as more particularly set forth in the Subordination
and Note Cancellation Agreement.  In the event that any conflict exists between
the terms of this Guaranty, any document executed in connection with the
delivery of this Guaranty and the terms of the Subordination and Note
Cancellation Agreement, the terms of the Subordination and Note Cancellation
Agreement shall govern and be controlling.

     11.  PAYMENTS; APPLICATION.  All payments to be made hereunder by Guarantor
shall be made in lawful money of the United States of America at the time of
payment, shall be made in immediately available funds, and shall be made without
deduction (whether for taxes or otherwise) or offset.  All payments made by
Guarantor hereunder shall be applied as follows: first, to all costs and
expenses (including attorneys' fees and expenses and attorneys' fees and
expenses incurred pursuant to proceedings arising under the Bankruptcy Code)
incurred by Guarantied Party in enforcing this Guaranty or in collecting the
Guaranteed Obligations; second,


                                          8
<PAGE>

to all accrued and unpaid interest, premium, if any, and fees owing to
Guarantied Party constituting Guaranteed Obligations; and third, to the balance
of the Guaranteed Obligations.

     12.  REPRESENTATIONS AND WARRANTIES.  Guarantor hereby represents and
warrants to Guarantied Party that:

          (a)  Guarantor is a corporation duly organized and existing under the
laws of Delaware and has the power and authority to own its own properties and
assets, and to transact the business in which it is engaged, and is properly

          (b)  The execution, delivery and performance of this Guaranty are

obligation, indenture or other instrument to which Guarantor is a party or by
which Guarantor is bound or affected.  There is no law, rule or regulation, nor
is there any judgment, decree or order of any court or governmental authority
binding on Guarantor which would be contravened by the execution, delivery,
performance or enforcement of this Guaranty.

          (c)  Guarantor has taken all corporate action necessary to authorize
the execution and delivery of this Guaranty, and the consummation of the
transactions contemplated hereby and thereby.  Upon their execution and delivery
in accordance with their respective terms, this Guaranty will constitute legal,
valid and binding agreements and obligations of Guarantor enforceable against
Guarantor in accordance with its terms, except as enforceability may be limited
by Bankruptcy, insolvency, fraudulent conveyance, and similar laws and equitable
principles affecting the enforcement of creditors' rights generally.

          (d)  No approval, consent, exemption or other action by, or notice to
or filing with, any governmental authority is necessary in connection with the
execution, delivery, performance or enforcement of this Guaranty except as may

Party's prior written consent and any such prohibited assignment shall be

relating to this Guaranty, or the breach thereof, shall be settled by
arbitration as set forth below.

          (a)  All disputes which in any manner arise out of or relate to this
Guaranty or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 23.  Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

          (b)  The parties stipulate to arbitration before a single, mutually
agreed upon arbitrator sitting on the Los Angeles, California Judicial
Arbitration Mediation Services (JAMS) panel.  In the event that the parties are

bar.

<PAGE>

          (c)  The parties shall share all costs of arbitration.  The prevailing
party shall be entitled to reimbursement by the other party of such party's
attorneys' fees and costs and any arbitration fees and expenses incurred in
connection with the arbitration hereunder.

          (d)  The substantive law of the State of California shall be applied

arbitrator and mailed to each of the parties and their legal counsel.

conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Guaranty.  The
arbitrator or a court of appropriate jurisdiction may issue a write of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

          (g)  Notwithstanding the foregoing, because time is of the essence of
this Guaranty, the parties specifically reserve the right to a judicial
temporary restraining order, preliminary injunction, or other similar equitable
relief.

          (h)  The decision and award of the arbitrator shall be kept
confidential by the parties to the greatest extent possible.  No disclosure of
such decision or award shall be made by the parties except as required by law or
as necessary or appropriate to effect the enforcement thereof.

          (i)  Should either party institute any action or procedure to enforce
this Guaranty or any provision hereof, or for damages by reason of any alleged
breach of this Guaranty or of any provision hereof, or for a declaration of
rights hereunder (including, without limitation, arbitration), the prevailing
party in any such action or proceeding shall be entitled to

with Physician's performance of his obligations hereunder.  The parties agree

spouse of Physician, from practicing medicine.

            During the Term, Physician shall not, at any time or place, either
directly or indirectly, engage in the practice of medicine or surgery to any

            (i)    If Employer, in good faith, determines that Physician is not

patients is jeopardized by continuing the employment of Physician.

            (j)    In the event the performance by either party hereto of any

payment programs; or if for any other reason said performance should be in

the parties shall use their best efforts to meet forthwith and attempt to
negotiate an amendment to this Agreement to remove or negate the effect of the
Jeopardy Event. In the event the parties are unable to negotiate such an
amendment within fifteen (15) days following such notice, then the provisions of
this Agreement that give rise to the Jeopardy Event shall be ineffective only to

of this Agreement, Physician will be provided full access to copy Employer
patient medical records in the event of a malpractice action or administrative
investigation or proceeding against Physician.

4.   CONFIDENTIALITY/TRADE SECRETS.   Physician acknowledges that his position
with the Practice will be one of the highest trust and confidence both by reason
of his position and by reason of his access to and contact with the trade
secrets and confidential and proprietary business information of Employer and
all of its Affiliates (as defined below), during the term of this Agreement and
thereafter.  Physician covenants and agrees as follows:

     4.1    PROTECTION.  That Physician shall use his best efforts and 
exercise utmost diligence to protect and safeguard the trade secrets and 
confidential and proprietary information of Employer and its "Affiliates" 
(which term as used in this Agreement shall include any person, corporation, 
partnership, general partner or other entity that (i) provides management or 
other 

                                       7
<PAGE>

services to the Practice ("Manager"), or (ii) directly, or indirectly through 
one or more intermediaries, controls or is controlled by or is under common 
control with Employer or Manager), including, without limitation, their trade 
secrets, proprietary information, the identity of their customers and 
suppliers, their arrangements with their customers and suppliers, and their 
technical data, records, compilations of information, processes, computer 
software, and specifications relating to their customers, suppliers, products 
and services (collectively, "Confidential Information").

     4.2    NONDISCLOSURE.  That Physician shall not disclose any Confidential
Information, except as may be required in the course of his employment or as may
be required by law.

     4.3    NON-USAGE.  That Physician shall not use, directly or indirectly,
for his own benefit or for the benefit of another, any Confidential Information.

     The covenants contained in this Section 4 shall not be applicable to any
information which is in the public domain other than as a result of action by
Physician or which Physician can establish was obtained from sources other than
Employer or any of its Affiliates, who are not under a duty of nondisclosure. 
All Confidential Information and all files, records, documents, drawings,
specifications, computer software, memorandums, notes, or other documents
relating thereto or otherwise relating to the business of Employer and its
Affiliates or the Practice, whether prepared by Physician or otherwise coming
into his possession, shall be the exclusive property of Employer (and/or its
Affiliates, as applicable) and shall be delivered to Employer or its Affiliates
as appropriate and not retained by (nor any copies thereof retained by)
Physician upon termination of his employment for any reason whatsoever.

5.   NON-SOLICITATION; NON-DIVERSION.

     5.1    PLAN MEMBER CONTACT.  Physician acknowledges and agrees that 
Employer has expended a great deal of time, effort and money in developing 
its business and obtaining the patients enrolled in prepaid capitated health 
plans (each a "Plan Member") that are enrolled with Employer, and that all of 
the patients to whom Physician renders professional medical services pursuant 
to this Agreement are and will remain patients of Employer ("Employer 
Patients"). Because of this, Employer considers, and Physician acknowledges, 
that the Employer Patients constitute an important corporate asset and 
Employer's Plan Member lists constitute valuable proprietary information.  In 
consideration of Employer providing current Employer Patients (I.E. Plan 
Members), as well as future Employer Patients, to Physician, Physician 
acknowledges and agrees that Employer will suffer irreparable harm and injury 
if Physician attempts to, or does, communicate with Employer Patients in any 
way concerning termination of this Agreement or concerning any other Employer 
business matter.  As such, Physician expressly waives any rights (including 
those set forth in California Business and Professions Code Section 651) to 
contact Employer Patients in any way about the termination of this Agreement 
or about any other Employer business matter.  Physician agrees that, except 
to the extent that Employer has provided written authorization, Physician 
shall not directly contact Employer Patients, their employers or 

                                       8
<PAGE>

health plans in regard to business related matters pertaining to Employer 
contracted heath plans including, but not limited to, (1) switching plans or 
similar entities or contracting directly with Physician (or some other 
provider organization that Physician is a member of) instead of Employer; (2) 
the options Employer Patients have to transfer to other plans (or to switch 
to other providers as a result of termination of this Agreement; or (3) the 
fact that the Employer Patient will no longer be able to obtain services from 
Physician.  Understanding and acknowledging the foregoing, Physician agrees 
to cooperate fully with Employer in any communications to Employer Patients 
concerning termination of this Agreement and other Employer business matters, 
and Physician agrees not to interfere in any way with the relationship 
between Employer and Employer Patients.  In the event that Physician violates 
this provision, Employer may seek a temporary restraining order and/or 
injunction to preclude such activity, as well as all appropriate damages 
resulting from Physician's breach of this provision.  Notwithstanding the 
foregoing, nothing contained herein shall be construed to limit the 
Physician's opportunity to discuss with any Employer Patient information 
relevant to such Employer Patient's medical condition, including such 
Employer Patient's treatment options, alternative plans or other coverage 
arrangements.

     5.2    NON-SOLICITATION OF PLAN MEMBERS.  As part of the consideration for
Employer to enter into this Agreement, during the initial and any succeeding
term of this Agreement and for a period of three (3) years following the date of
termination of this Agreement, Physician will not directly or indirectly, either
individually or on behalf of or as a provider for any person or entity other
than Employer whose business competes with the business of Employer, (i) advise
any Employer Plan Member or patient to disenroll from Employer, or (ii) solicit
any Plan Member or patient or any Plan Member's or patient's employer to become
enrolled with any other health maintenance organization, provider organization,
or any other similar hospitalization or medical payment plan or insurance
program.  Physician shall use his best efforts to ensure that no employee, agent
or independent contractor of Physician makes any derogatory remarks regarding
Employer to any Plan Member, Plan Member's employer, health plan or health
maintenance organization.

     5.3    OTHER AGREEMENTS FOLLOWING TERMINATION.  Nothing contained herein
shall prevent Physician, following the termination of this Agreement, from:

            (a)    Entering into contracts or other agreements with any
capitated health plan that does not have an agreement or contract with Employer
as of the date of this Agreement; 

            (b)    Providing services to fee for service patients; or 

            (c)    Joining or otherwise becoming a member of an independent
practice association or physician network.

     Notwithstanding the foregoing, in the event an Employer Patient seeks, 
without being solicited or otherwise contacted by Physician or any agent of 
Physician in violation of the 

                                       9
<PAGE>

provisions of Sections 5.1 and 5.2 herein, to receive medical services from 
Physician and Physician desires to provide medical services to such former 
Employer Patient, Physician shall only be entitled to provide such services 
as an outside provider of Employer under the terms of Employer's standard 
participating provider agreement then in effect, and pursuant to Employer's 
agreement with the respective health plan under which the capitation payments 
for such former Employer Patient are paid.

6.   REMEDIES FOR BREACH OF COVENANTS OF PHYSICIAN.  The covenants set forth in
Sections 4 and 5 of this Agreement shall continue to be binding upon Physician
notwithstanding the termination of his employment with Employer for any reason
whatsoever.  Such covenants shall be deemed and construed as separate agreements
independent of any other provision of this Agreement.  The existence of any
claim or cause of action by Physician against Employer or any of its Affiliates,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by Employer or any of its Affiliates of any or all of
such covenants.  It is expressly agreed that the remedy at law for the breach of
any such covenant is inadequate and that temporary and permanent injunctive
relief shall be available to prevent the breach or any threatened breach
thereof, without the necessity of proof of actual damages and without the
necessity of posting a bond, cash or otherwise.  In this connection, Physician
agrees not to assert any defense that monetary damages would be sufficient.

7.   DEFAULT.  Any default by Employer in the payment when due, of any amount
owed by Employer to Physician under the Contingent Promissory Note, of even date
herewith, payable from Employer to Physician, in the principal amount of
$1,125,000, which default continues for a period of ten (10) days, shall
constitute a default under this Agreement.  Upon written notice from Physician
of such default, Employer shall have a thirty (30) day period in which to cure
such default.  In the event Employer fails to cure such default within thirty
(30) days of such notice, at Physician's option, except for the provisions
contained in Sections 4 and 5 hereinabove, which shall remain in full force and
effect, this Agreement shall terminate and Physician shall have no further
obligations hereunder.

8.   ARBITRATION.  The parties firmly desire to resolve all disputes arising
hereunder without resort to litigation in order to protect their respective
business reputations and the confidential nature of certain aspects of their
relationship.  Accordingly, any controversy or claim arising out of or relating
to this Agreement, or the breach thereof, shall be settled by arbitration as set
forth below.

     8.1    All disputes which in any manner arise out of or relate to this
Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 8.  Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.


                                      10
<PAGE>

     8.2    There shall be one arbitrator.  If the parties shall fail to select
a mutually acceptable arbitrator within ten (10) days after the demand for
arbitration is mailed, then the parties stipulate to arbitration before a single
arbitrator sitting on the Los Angeles, California Judicial Arbitration Mediation
Services (JAMS) panel, and selected in the sole discretion of the JAMS
administrator.

     8.3    The parties shall share all costs of arbitration.  The prevailing
party shall be entitled to reimbursement by the other party of such party's
attorneys' fees and costs and any arbitration fees and expenses incurred in
connection with the arbitration hereunder.

     8.4    The substantive law of the State of California shall be applied by
the arbitrator.

     8.5    Arbitration shall take place in Los Angeles, California unless the
parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable thereafter, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

     8.6    All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement.  The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

     8.7    Notwithstanding the foregoing, because time is of the essence of
this Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar short term
equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or
dissolve such court order.

     8.8    The decision and award of the arbitrator shall be kept confidential
by the parties to the greatest extent possible.  No disclosure of such decision
or award shall be made by the parties except as required by law or as necessary
or appropriate to effect the enforcement thereof.

9.   CONTRACTS.  Physician shall not have the right or authority and hereby
expressly covenants not to, enter into a contract in the name of Employer or the
Practice or otherwise bind Employer or the Practice, in any way, without the
express written consent of Employer.  Physician shall hold Employer and the
Practice harmless from any loss attributable to a violation of this covenant.  

10.  USE OF PREMISES.  Physician covenants not to use, or permit any other
personnel under the control of Physician to use, any part of the premises of the
Practice for any purpose other than the performance of services hereunder.

or reappointment of membership on the medical staff of any hospital, and no 
hospital medical staff membership or clinical privileges of Physician have

above becomes untrue or inaccurate in any material respect during the Term 
(as hereinafter defined), Physician shall send the Practice a notice (the 
"Physician Warranty Notice") within ten (10) days thereafter setting forth

("collected revenues"), and Physician agrees that Physician shall not take 
any actions whatsoever to bill (or cause to be billed, other than by Employer 
or its designee) any patient or other individual or entity for any such 
services. The fees for services rendered by Physician shall be established by 
Employer. The fees for services may be changed from time to time by Employer 
to reflect charges that may have been agreed upon between Employer and 
third-party providers, including insurance companies, managed care plans, 
HMOs and PPOs. Employer (or its designee) shall bill Physician's charges and 
collect payments for all Physician's services, and Physician agrees to work 
with Employer's office staff to ensure the prompt billing of all patients for 
all services rendered and to use his or her best efforts to help office staff 
(or Employer's designee) collect all patient accounts. The "Physician 
charges" shall mean all billings for all of Physician's services provided 
hereunder. All fees from billings generated by Physician shall be the sole

transfers, assigns or otherwise conveys to Employer all right, title and 
interest of Physician in and to any fees resulting from or incident to 
Physician's practice of medicine under this Agreement.

with others, including covering calls for other physicians except as an 
employee of Employer and for the benefit of Employer and the Practice.  
Further, Physician shall not become an employee of any other group, hospital 
or institution wherein Physician provides direct or indirect services to 
patients of such entities.  Except for services rendered in Physician's 
internal medicine and gastroenterology practice, as provided hereinbelow, all 
fees and billings produced by Physician for services for patients other than 
patients of the Practice shall be income of the Practice. Physician's duties 
shall include, but not be limited to the following:

            (a)    Providing professional medical services within Physician's 
field of practice to any and all patients of the Practice in any office of

claims reports and 


                                      3

correspondence (including, without limitation, patient charts) relating to 
all services rendered by him under this Agreement in accordance with all 
Practice, professional, and governmental record keeping and reporting 
requirements, all of which records shall be and remain the property or in the 
possession of Employer;

seminars and generally performing all things necessary to maintain and

            (d)    Performing such other duties as Employer shall from time 
to time reasonably direct.

            Nothing in this Agreement is intended nor shall be construed as 
limiting or restricting Physician's right to engage in any activity unrelated 
to the direct practice of medicine, provided that such activities do not 
interfere with Physician's performance of his or her obligations hereunder.

            During the Term, Physician shall not, at any time or place, 
either directly or indirectly, engage in the practice of medicine or surgery 
to any extent whatsoever, except pursuant to and in accordance with this 
Agreement. Except as otherwise expressly provided herein, Physician shall 
comply with all policies and procedures applicable to Practice employees 
generally. Notwithstanding the foregoing, Physician shall be entitled to 
maintain an internal medicine and gastroenterology practice located at 44725 
10th Street West, Suite 250, Lancaster, CA 93534 provided that he shall not 
perform medical services for any capitated primary care patient outside his 
employment with Employer.

            Nothing herein shall be construed to prevent Physician from 
receiving honoraria or other stipends for performing services outside the 
scope of his employment hereunder; provided however, that Physician shall not 
perform any such services on behalf of any competitor of Employer or its 
affiliates.

            (e)    Upon the imposition of any restrictions or limitations on

<PAGE>


adequate patient care or that the health, safety or welfare of patients is 
jeopardized by continuing the employment of Physician.

            (j)    In the event the performance by either party hereto of any 
term, covenant, condition or provision of this Agreement should jeopardize 
(1) the licensure of Employer, any Affiliate of Employer, or Physician, or 
(2) Employer's (or any Affiliate's) or Physician's participation in, or 
reimbursement from, Medicare, Medicaid (Medi-Cal) or other reimbursement or 
payment programs; or if for any other reason said performance should be in 
violation of any statute, ordinance, or be otherwise deemed illegal, by a 
state or federal court or governmental agency (collectively, "Jeopardy 
Event"), then the parties shall use their best efforts to meet forthwith and 
attempt to negotiate an amendment to this Agreement to remove or negate the 
effect of the Jeopardy Event. In the event the parties are unable to 
negotiate such an amendment within fifteen (15) days following such notice, 
then the provisions of this Agreement that give rise to the Jeopardy Event 
shall be ineffective only to the extent that they are in contravention of 
applicable law or otherwise give rise to the Jeopardy Event, without 
invalidating the remaining provisions of this Agreement, unless the same 
should defeat an essential business purpose of this Agreement.

     3.4    TERMINATION BY PHYSICIAN.  Physician may terminate his or her 
employment hereunder at any time for "cause." Cause is limited to a material 
breach by Employer of a material term of this Agreement by Employer.  In the

receive accrued but unpaid salary through the date of such termination. Upon 
and after termination of this Agreement, Physician will be provided full 
access to copy Employer patient medical records in the event of a malpractice 
action or administrative investigation or proceeding against Physician.

4.   CONFIDENTIALITY/TRADE SECRETS.  Physician acknowledges that his position 
with the Practice will be one of the highest trust and confidence both by 
reason of his position and by reason of his access to and contact with the 
trade secrets and confidential and proprietary business information of 
Employer and all of its Affiliates (as defined below), during the term of 
this Agreement and thereafter.  Physician covenants and agrees as follows:

     4.1    PROTECTION.  That Physician shall use his best efforts and 
exercise utmost diligence to protect and safeguard the trade secrets and 
confidential and proprietary information of Employer and its "Affiliates" 
(which term as used in this Agreement shall include any person, corporation, 
partnership, general partner or other entity that (i) provides management or 
other services to the Practice ("Manager"), or (ii) directly, or indirectly 
through one or more intermediaries, controls or is controlled by or is under 
common control with Employer or 


                                      7
<PAGE>


Manager), including, without limitation, their trade secrets, proprietary 
information, the identity of their customers and suppliers, their 
arrangements with their customers and suppliers, and their technical data, 
records, compilations of information, processes, computer software, and 
specifications relating to their customers, suppliers, products and services 
(collectively, "Confidential Information").

     4.2    NONDISCLOSURE.  That Physician shall not disclose any 
Confidential Information, except as may be required in the course of his 
employment or as may be required by law.

     4.3    NON-USAGE.  That Physician shall not use, directly or indirectly, 
for his own benefit or for the benefit of another, any Confidential 
Information.

     The covenants contained in this Section 4 shall not be applicable to any 
information which is in the public domain other than as a result of action by 
Physician or which Physician can establish was obtained from sources other 
than Employer or any of its Affiliates, who are not under a duty of 
nondisclosure. All Confidential Information and all files, records, 
documents, drawings, specifications, computer software, memorandums, notes, 
or other documents relating thereto or otherwise relating to the business of 
Employer and its Affiliates or the Practice, whether prepared by Physician or 
otherwise coming into his possession, shall be the exclusive property of 
Employer (and/or its Affiliates, as applicable) and shall be delivered to 
Employer or its Affiliates as appropriate and not retained by (nor any copies 
thereof retained by) Physician upon termination of his employment for any 
reason whatsoever.

5.   NON-SOLICITATION; NON-DIVERSION.

     5.1    PLAN MEMBER CONTACT.  Physician acknowledges and agrees that 
Employer has expended a great deal of time, effort and money in developing 
its business and obtaining the patients enrolled in prepaid capitated health 
plans (each a "Plan Member") that are enrolled with Employer, and that all of 
the patients to whom Physician renders professional medical services pursuant 
to this Agreement are and will remain patients of Employer ("Employer 
Patients"). Because of this, Employer considers, and Physician acknowledges, 
that the Employer Patients constitute an important corporate asset and 
Employer's Plan Member lists constitute valuable proprietary information.  In 
consideration of Employer providing current Employer Patients (I.E. Plan 
Members), as well as future Employer Patients, to Physician, Physician 
acknowledges and agrees that Employer will suffer irreparable harm and injury 
if Physician attempts to, or does, communicate with Employer Patients in any 
way concerning termination of this Agreement or concerning any other Employer 
business matter.  As such, Physician expressly waives any rights (including 
those set forth in California Business and Professions Code Section 651) to 
contact Employer Patients in any way about the termination of this Agreement 
or about any other Employer business matter.  Physician agrees that, except 
to the extent that Employer has provided written authorization, Physician 
shall not directly contact Employer Patients, their employers or health plans 
in regard to business related matters pertaining to Employer contracted heath 
plans including, but not limited to, (1) switching plans or similar entities 
or contracting directly with 


                                      8
<PAGE>


Physician (or some other provider organization that Physician is a member of) 
instead of Employer; (2) the options Employer Patients have to transfer to 
other plans (or to switch to other providers as a result of termination of 
this Agreement; or (3) the fact that the Employer Patient will no longer be 
able to obtain services from Physician.  Understanding and acknowledging the 
foregoing, Physician agrees to cooperate fully with Employer in any 
communications to Employer Patients concerning termination of this Agreement 
and other Employer business matters, and Physician agrees not to interfere in 
any way with the relationship between Employer and Employer Patients.  In the 
event that Physician violates this provision, Employer may seek a temporary 
restraining order and/or injunction to preclude such activity, as well as all 
appropriate damages resulting from Physician's breach of this provision.  
Notwithstanding the foregoing, nothing contained herein shall be construed to 
limit the Physician's opportunity to discuss with any Employer Patient 
information relevant to such Employer Patient's medical condition, including 
such Employer Patient's treatment options, alternative plans or other 
coverage arrangements.

     5.2    NON-SOLICITATION OF PLAN MEMBERS.  As part of the consideration 
for Employer to enter into this Agreement, during the initial and any 
succeeding term of this Agreement and for a period of three (3) years 
following the date of termination of this Agreement, Physician will not 
directly or indirectly, either individually or on behalf of or as a provider 
for any person or entity other than Employer whose business competes with the 
business of Employer, (i) advise any Employer Plan Member or patient to 
disenroll from Employer, or (ii) solicit any Plan Member or patient or any 
Plan Member's or patient's employer to become enrolled with any other health 
maintenance organization, provider organization, or any other similar 
hospitalization or medical payment plan or insurance program.  Physician 
shall use his best efforts to ensure that no employee, agent or independent 
contractor of Physician makes any derogatory remarks regarding Employer to 
any Plan Member, Plan Member's employer, health plan or health maintenance 
organization.

     5.3    OTHER AGREEMENTS FOLLOWING TERMINATION.  Nothing contained herein 
shall prevent Physician, following the termination of this Agreement, from:

            (a)    Entering into contracts or other agreements with any 
capitated health plan that does not have an agreement or contract with 
Employer as of the date of this Agreement; 

            (b)    Providing services to fee for service patients; or 

            (c)     Joining or otherwise becoming a member of an independent 
practice association or physician network.

     Notwithstanding the foregoing, in the event an Employer Patient seeks, 
without being solicited or otherwise contacted by Physician or any agent of 
Physician in violation of the provisions of Sections 5.1 and 5.2 herein, to 
receive medical services from Physician and Physician desires to provide 
medical services to such former Employer Patient, Physician shall 


                                      9
<PAGE>


only be entitled to provide such services as an outside provider of Employer 
under the terms of Employer's standard participating provider agreement then 
in effect, and pursuant to Employer's agreement with the respective health 
plan under which the capitation payments for such former Employer Patient are 
paid.

6.   REMEDIES FOR BREACH OF COVENANTS OF PHYSICIAN.  The covenants set forth 
in Sections 4 and 5 of this Agreement shall continue to be binding upon 
Physician notwithstanding the termination of his employment with Employer for 
any reason whatsoever.  Such covenants shall be deemed and construed as 
separate agreements independent of any other provision of this Agreement.  
The existence of any claim or cause of action by Physician against Employer 
or any of its Affiliates, whether predicated on this Agreement or otherwise, 
shall not constitute a defense to the enforcement by Employer or any of its 
Affiliates of any or all of such covenants.  It is expressly agreed that the 
remedy at law for the breach of any such covenant is inadequate and that 
temporary and permanent injunctive relief shall be available to prevent the 
breach or any threatened breach thereof, without the necessity of proof of 
actual damages and without the necessity of posting a bond, cash or 
otherwise.  In this connection, Physician agrees not to assert any defense 
that monetary damages would be sufficient.

7.   DEFAULT.  Any default by Employer in the payment when due of any amount 
owed by Employer to Physician under the Contingent Promissory Note, of even 
date herewith, issued from Employer to Physician, in the principal amount of 
$1,125,000, which default continues for a period of ten (10) days, shall 
constitute a default under this Agreement.  Upon written notice from 
Physician of such default, Employer shall have a thirty (30) day period in 
which to cure such default.  In the event Employer fails to cure such default 
within thirty (30) days of such notice, at Physician's option, except for the 
provisions continued in Sections 4 and 5 hereinabove, which shall remain in 
full force and effect, this Agreement shall terminate and Physician shall 
have no further obligations hereunder.

8.   ARBITRATION.  The parties firmly desire to resolve all disputes arising 
hereunder without resort to litigation in order to protect their respective 
business reputations and the confidential nature of certain aspects of their 
relationship.  Accordingly, any controversy or claim arising out of or 
relating to this Agreement, or the breach thereof, shall be settled by 
arbitration as set forth below.

     8.1    All disputes which in any manner arise out of or relate to this 
Agreement or the subject matter thereof, shall be resolved exclusively by 
arbitration in accordance with the provisions of this Section 8.  Either 
party may commence arbitration by sending a written demand for arbitration to 
the other party, setting forth the nature of the controversy, the dollar 
amount involved, if any, and the remedies sought, and attaching a copy of 
this Section to the demand.

     8.2    There shall be one arbitrator.  If the parties shall fail to 
select a mutually acceptable arbitrator within ten (10) days after the demand 
for arbitration is mailed, then the parties stipulate to arbitration before a 
single arbitrator sitting on the Los Angeles, California Judicial Arbitration 


                                      10
<PAGE>


Mediation Services (JAMS) panel, and selected in the sole discretion of the 
JAMS administrator.

     8.3    The parties shall share all costs of arbitration.  The prevailing 
party shall be entitled to reimbursement by the other party of such party's 
attorneys' fees and costs and any arbitration fees and expenses incurred in 
connection with the arbitration hereunder.

     8.4    The substantive law of the State of California shall be applied 
by the arbitrator. 

     8.5    Arbitration shall take place in Los Angeles, California unless 
the parties otherwise agree.  As soon as reasonably practicable, a hearing 
with respect to the dispute or matter to be resolved shall be conducted by 
the arbitrator.  As soon as reasonably practicable thereafter, the arbitrator 
shall arrive at a final decision, which shall be reduced to writing, signed 
by the arbitrator and mailed to each of the parties and their legal counsel.

     8.6    All decisions of the arbitrator shall be final, binding and 
conclusive on the parties and shall constitute the only method of resolving 
disputes or matters subject to arbitration pursuant to this Agreement.  The 
arbitrator or a court of appropriate jurisdiction may issue a writ of 
execution to enforce the arbitrator's judgment.  Judgment may be entered upon 
such a decision in accordance with applicable law in any court having 
jurisdiction thereof.

     8.7    Notwithstanding the foregoing, because time is of the essence of 
this Agreement, the parties specifically reserve the right to seek a judicial 
temporary restraining order, preliminary injunction, or other similar short 
term equitable relief, and grant the arbitrator the right to make a final 
determination of the parties' rights, including whether to make permanent or 
dissolve such court order.

     8.8    The decision and award of the arbitrator shall be kept 
confidential by the parties to the greatest extent possible.  No disclosure 
of such decision or award shall be made by the parties except as required by 
law or as necessary or appropriate to effect the enforcement thereof.

9.   CONTRACTS.  Physician shall not have the right or authority and hereby 
expressly covenants not to, enter into a contract in the name of Employer or 
the Practice or otherwise bind Employer or the Practice, in any way, without 
the express written consent of Employer.  Physician shall hold Employer and 
the Practice harmless from any loss attributable to a violation of this 
covenant.  

10.  USE OF PREMISES.  Physician covenants not to use, or permit any other 
personnel under the control of Physician to use, any part of the premises of 
the Practice for any purpose other than the performance of services hereunder.

11.  MISCELLANEOUS.  

     11.1   NOTICES.  Any notice, demand, or communication required,

or amount of reimbursement or payment for services under this Agreement, or 
(ii) any or all of such payors/authorities impose requirements which require 
a material change in the manner of either party's operations under this 
Agreement and/or the costs related thereto, then, upon the request of either 
party materially affected by any such change in circumstances, the parties 
shall enter into good faith negotiations for the purpose of establishing such 
amendments or modifications as may be appropriate in order to accommodate the 
new requirements and change of circumstances while preserving the original 
intent of this Agreement to the greatest extent possible. If, after thirty 
(30) days of such negotiations, the parties are unable to reach an agreement

accordance with the laws of the State of California.

     I.     INJUNCTIVE RELIEF.  The parties hereto acknowledge and agree that a
breach by Physician of this Agreement will cause irreparable damage to
Purchaser, the exact amount of which will be difficult to ascertain, and that
remedies at law for any such breach will be inadequate.  Accordingly, Physician

affected, unless such invalidity or unenforceability would defeat an essential
business purpose of this Agreement.  Without limiting the generality of the
foregoing, if the provisions of this Agreement shall be deemed to create a
restriction which is unreasonable as to either duration or geographical area, or
both, the parties agree that the provisions of this Agreement shall be enforced
for such duration and in such geographical area as any court of competent
jurisdiction may determine to be reasonable.

     K.     ATTORNEYS' FEES.  Should either Purchaser or Physician institute any
action or procedure to enforce this Agreement or any provision hereof, or for
damages by reason of any alleged breach of this Agreement or of any provision
hereof, or for a declaration of rights hereunder (including without limitation
arbitration), the prevailing party in any such action or proceeding shall be
entitled to receive from the other party all costs and expenses, including
without limitation reasonable attorneys' fees, incurred by the prevailing party
in connection with such action or proceeding.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement of the
day and year first written above.

remainder of this Agreement will nevertheless continue in full force and effect
and shall not be invalidated or rendered unenforceable or otherwise adversely
affected, unless such invalidity or unenforceability would defeat an essential
business purpose of this Agreement.  Without limiting the generality of the
foregoing, if the provisions of this Agreement shall be deemed to create a
restriction which is unreasonable as to either duration or geographical area, or
both, the parties agree that the provisions of this Agreement shall be enforced
for such duration and in such geographical area as any court of competent
jurisdiction may determine to be reasonable.

     K.     ATTORNEYS' FEES.  Should either Purchaser or Physician institute any
action or procedure to enforce this Agreement or any provision hereof, or for
damages by reason of any alleged breach of this Agreement or of any provision
hereof, or for a declaration of rights hereunder (including without limitation
arbitration), the prevailing party in any such action or proceeding shall be
entitled to receive from the other party all costs and expenses, including
without limitation reasonable attorneys' fees, incurred by the prevailing party
in connection with such action or proceeding.

4.   CONFIDENTIALITY/TRADE SECRETS.  Employee acknowledges that his position
with Employer will be one of the highest trust and confidence both by reason of
his position and by reason of his access to and contact with the trade secrets
and confidential and propriety business information of Employer and all of its
Affiliates (as defined below), during the term of this Agreement and thereafter.
Employee covenants and agrees at all times during and after the term of this
Agreement as follows:

     4.1  PROTECTION.  That Employee shall use his best efforts and exercise
utmost diligence to protect and safeguard the trade secrets and confidential and
proprietary information of Employer and its "Affiliates" (which term as used in
this Agreement shall include any person, corporation, partnership, general
partner or other entity that directly, or indirectly through one or more
intermediaries, controls or is controlled by or is under common control with
Employer), including, without limitation, their trade secrets, proprietary
information, the identity of their customers and suppliers, their arrangements
with their customers and suppliers, and their technical data, records,
compilations of information, processes, computer software, and specifications
relating to their customers, suppliers, products and services (collectively,
"Confidential Information").

     4.2  NON-DISCLOSURE.  That Employee shall not disclose any Confidential
Information, except as may be required in the course of his employment or as
may be required by law.

     4.3  NON-USAGE.  That Employee shall not use, directly or indirectly, for
his  own benefit or for the benefit of another, any Confidential Information.

     The covenants contained in this Section 4 shall not be applicable to any
information which is in the public domain other than as a result of action by
Employee or which Employee can establish was obtained from sources other than
Employer or any of its Affiliates, who are not under a duty of nondisclosure.
All Confidential Information and all files, records, documents, drawings,
specifications, computer software, memoranda, notes, or other documents relating
thereto or otherwise relating to the business of Employer and its Affiliates,
whether prepared by Employee or otherwise coming into his  possession, shall be
the exclusive property of Employer (and/or its Affiliates, as applicable) and
shall be delivered to Employer or its Affiliates as appropriate and not retained
by (nor any copies thereof retained by) Employee upon termination of his
employment for any reason whatsoever.

5.   REMEDIES FOR BREACH OF COVENANTS OF EMPLOYEE.  The covenants set forth in
Section 4 of this Agreement shall continue to be binding upon Employee
notwithstanding the termination of his employment with Employer for any reason
whatsoever.  Such covenants shall be deemed and construed as separate agreements
independent of any other provision of this Agreement.  The existence of any
claim or cause of action by Employee against Employer or any of its Affiliates,
whether predicated on this Agreement or otherwise, shall not constitute a
defense to the enforcement by Employer or any of its Affiliates of any or all of
such covenants.  It is expressly agreed that the remedy at law for the breach of
any such covenant is inadequate and that temporary and permanent injunctive
relief shall be available to prevent the breach or any threatened breach
thereof, without the necessity of proof of actual damages and without the
necessity of posting a bond, cash or otherwise.  In this connection, Employee
agrees not to assert any defense that monetary damages would be sufficient.


                                         G-4
<PAGE>

6.   DEFAULT.  Any default by Prospect Medical Holdings, Inc. in the payment
when due, of any amount owed by Prospect Medical Holdings, Inc. to Employee
under the Promissory Note, of even date herewith, issued from Prospect Medical
Holdings, Inc. to Employee, in the principal amount of $250,000, which default
continues for a period of ten (10) days, shall constitute a default under this
Agreement.  Upon written notice from Employee of such default, Prospect Medical
Holdings, Inc. shall have a thirty (30) day period in which to cure such
default.  In the event Prospect Medical Holdings, Inc. fails to cure such
default within thirty (30) days of such notice, at Employee's option, this
Agreement shall terminate and Employee shall have no further obligations
hereunder.

7.   ARBITRATION.  The parties firmly desire to resolve all disputes arising
hereunder without resort to litigation in order to protect their respective
business reputations and the confidential nature of certain aspects of their
relationship.  Accordingly, any controversy or claim arising out of or relating
to this Agreement, or the breach thereof, shall be settled by arbitration as set
forth below.

     7.1  All disputes which in any manner arise out of or relate to this
Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 7.  Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

     7.2  There shall be one arbitrator.  If the parties shall fail to select a
mutually acceptable arbitrator within ten (10) days after the demand for
arbitration is mailed, then the parties stipulate to arbitration before a single
arbitrator sitting on the Los Angeles, California Judicial Arbitration Mediation
Services (JAMS) panel, and selected in the sole discretion of the JAMS
administrator.

     7.3  The parties shall share all costs of arbitration.  The prevailing
party shall be entitled to reimbursement by the other party of such party's
attorneys' fees and costs and any arbitration fees and expenses incurred in
connection with the arbitration hereunder.

     7.4  The substantive law of the State of California shall be applied by the
arbitrator.

     7.5  Arbitration shall take place in Los Angeles, California unless the
parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable thereafter, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

     7.6  All decisions of the arbitrator shall be final, binding and conclusive
on the parties and shall constitute the only method of resolving disputes or
matters subject to arbitration pursuant to this Agreement.  The arbitrator or a
court of appropriate jurisdiction may issue a writ of execution to enforce the
arbitrator's judgment.  Judgment may be entered upon such a decision in
accordance with applicable law in any court having jurisdiction thereof.

     7.7  Notwithstanding the foregoing, because time is of the essence of this
Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar short term
equitable relief, and grant the arbitrator the right to make a


                                         G-5
<PAGE>

final determination of the parties' rights, including whether to make permanent
or dissolve such court order.

     7.8  The decision and award of the arbitrator shall be kept confidential by
the parties to the greatest extent possible.  No disclosure of such decision or
award shall be made by the parties except as required by law or as necessary or
appropriate to effect the enforcement thereof.

     7.8    INJUNCTIVE RELIEF.  The parties hereto acknowledge and agree that a

business purpose of this Agreement.  Without limiting the generality of the
foregoing, if the provisions of this Agreement shall be deemed to create a
restriction which is unreasonable as to either duration or geographical area, or
both, the parties agree that the provisions of this Agreement shall be enforced

jurisdiction may determine to be reasonable.

action or proceeding shall be entitled to receive from the other party all costs
and expenses, including without limitation reasonable attorneys' fees, incurred

$250,000                                                      September 25, 1997
                                                         Los Angeles, California

     For value received, the undersigned Prospect Medical Holdings promises to
pay to Jayaratnam Jayakumar ("Holder"), at 44343 Soft Avenue, Lancaster, CA
93536, or at such other place as Holder may from time to time designate, the
principal sum of Two Hundred Fifty Thousand Dollars ($250,000), payable interest
only on the tenth (10) day of each month on the unpaid principal balance at the
rate of seven percent (7%) per annum, with principal payable (i) in quarterly
installments of $12,500 plus (ii) annual payments of $25,000 and continuing
thereafter for 18 months until March 24, 1999 (the "Maturity Date"), when the
unpaid principal balance of this Subordinated Promissory Note ("Note") then
outstanding, and all accrued but unpaid interest, shall be due and payable in
full.

     Should interest not be paid when due, it shall thereafter bear like 
interest as the principal, but such unpaid interest so compounded shall not 
exceed an amount equal to simple interest on the unpaid principal at the 
maximum rate permitted by the laws of the State of California.  Prospect 
Medical Holdings shall at its option be eligible to receive a one-time six

of such extension election not later than thirty 

<PAGE>

(30) days prior to the Maturity Date, with principal payments continuing and 
7% interest to be paid monthly on the unpaid principal.

     Prospect Medical Holdings may assign its obligations under this Note to 
an affiliate at any time provided such affiliate accepts such assignment and 
assumes all of the obligations set forth herein.  No such assignment shall 
relieve Prospect Medical Holdings of its obligations hereunder.  This Note is 
non-negotiable and may not be assigned by Holder.

     Holder may waive compliance with any of the provisions of this Note.

     At the option of the holder hereof, this Note shall be immediately due and
payable, without notice or demand, upon the occurrence at any time of any of the
following events:

     1.   DEFAULT.  Any default in the payment of principal or interest when due
hereunder; and

     2.   BANKRUPTCY.  The commencement of proceedings in bankruptcy, or for the
reorganization of any party liable hereon, whether as maker, endorser,
guarantor, surety or otherwise, or for the readjustment of any of the debts of
any of the foregoing parties, under the Federal Bankruptcy Code, as amended, or
any part thereof, or under any other laws, whether state or federal, for the
relief of debtors, now or hereafter existing, by any of the foregoing parties,
or against any of the foregoing parties, which shall not be discharged within
thirty (30) days of their commencement.

     Prospect Medical Holdings may, at any time and from time to time, without
penalty, make prepayments which will be applied to the final payment of
principal under this Note, or the principal components of the remaining payments
under this Note in the order or inverse order of maturity, all as the Prospect
Medical Holdings hereof may determine.

     In the event AV Hospital, or its affiliates, acquires a portion of
Purchaser's ownership interest in any affiliate of Sierra Primary Care Medical
Group, Inc., a California professional corporation, Prospect Medical Holdings
agrees to use up to 25% of any cash proceeds received by it or Prospect Medical
Group, Inc., a California professional corporation ("Prospect Medical Group") in
such transaction to prepay, on a pro-rata basis, this Note and promissory notes
issued to Sinnadurai E. Moorthy, M.D. and Karunyan Arulanantham, M.D., each in
the principal amount of $1,125,000.

     Presentment, demand and protest, and notices of protest, dishonor, and
non-payment of this Note and all notices of every kind, are hereby waived.

     No single or partial exercise of any power hereunder shall preclude the
other or further exercise thereof or the exercise of any other power.  No delay
or omission on the part of the holder hereof in exercising any right hereunder
shall operate as a waiver of such right or of any other right under this Note.

     The payments under this Note are subject to the rights of recoupment, 
offset, and setoff available to Prospect Medical Holdings based on any 
misrepresentation, any breach of any warranty, or any other breach of the 
Agreement of Reorganization by Holder.  In exercising its rights of 

                                     C-2
<PAGE>

recoupment, offset, or setoff, Prospect Medical Holdings shall not hold back 
and keep from the total outstanding principal balance more than the amount of 
the liability, loss, costs, or expense.

     Prospect Medical Holdings agrees, and the Holder of this Note by acceptance
hereof likewise agrees, that, notwithstanding the terms of this Note, the
payment of the principal, interest and any other amounts due under this Note is
subordinated, to the extent and in the manner set forth in the Subordination
Agreement, to the prior payment of all indebtedness and obligations of Prospect
Medical Holdings owing to Bank, as more particularly set forth in the
Subordination Agreement.  In the event that any conflict exists between the
terms of this instrument, any document executed in connection with the delivery
of this instrument and the terms of the Subordination Agreement, the terms of
the Subordination Agreement shall govern and be controlling.

     This Note shall be governed by and construed in accordance with the laws of
the State of California.

                           OPTION TO PURCHASE COMMON STOCK
                                          OF
                           PROSPECT MEDICAL HOLDINGS, INC.


     This is to Certify that, FOR VALUE RECEIVED, Jayaratnam Jayakumar, or 
assigns ("Holder"), is entitled to purchase, subject to the provisions of 
this Option, from Prospect Medical Holdings, Inc., a Delaware corporation 
("Company"), 3,500 shares of Common Stock, $0.01 par value, of the Company 
("Common Stock") at a price of $5.00 per share at any time during the period 
from the date hereof to five (5) years from the date hereof (the "Expiration 
Date"), but not later than 5:00 p.m., New York Time, on the Expiration Date. 
Such number and price may be adjusted from time to time as hereinafter set 
forth.  The shares of Common Stock deliverable upon such exercise and as 
adjusted from time to time are hereinafter sometimes referred to as "Option 
Shares" and the exercise price of each share of Common Stock in effect at any 
time and as adjusted from time to time is hereinafter sometimes referred to 
as the "Exercise Price".

     (a)  EXERCISE OF OPTION.  Subject to the provisions of Section (j) 
hereof, this Option may be exercised in whole or in part at any time or from 
time to time on or after the date hereof and until the Expiration Date, or if 
any such day is a day on which banking institutions in the State of New York 
are authorized by law to close, then on the next succeeding day which shall 
not be such a day, by presentation and surrender hereof to the Company at its 
principal office, or at the office of its stock transfer agent, if any, with 
the Purchase Form annexed hereto duly executed and accompanied by payment of 
the Exercise Price for the number of Option Shares specified in such form.  
If this Option should be exercised in part only, the Company shall, upon 
surrender of this Option for cancellation, execute and deliver a new Option 
evidencing the rights of the Holder thereof to purchase the balance of the 
Option Shares purchasable thereunder.  Upon receipt by the Company of this 
Option at its office, or by the stock transfer agent of the Company at its 
office, in proper form for exercise, the Holder shall be deemed to be the 
holder of record of the shares of Common Stock issuable upon such exercise, 
notwithstanding that the stock transfer books of the Company shall then be 
closed or that certificates representing such shares of Common Stock shall 
not then be actually delivered to the Holder.


<PAGE>


     (b)  RESERVATION OF SHARES.  The Company hereby agrees that at all times 
there shall be reserved for issuance and/or delivery upon exercise of this 
Option such number of shares of its Common Stock as shall be required for 
issuance and delivery upon exercise of this Option.

     (c)  FRACTIONAL SHARES.  No fractional shares or script representing 
fractional shares shall be issued upon the exercise of this Option.  With 
respect to any fraction of a share called for upon any exercise hereof, the 
Company shall pay to the Holder an amount in cash equal to such fraction 
multiplied by the current market value of a share, determined as follows:

          (1)  If the Common Stock is listed on a National Securities 
     Exchange or admitted to unlisted trading privileges on such exchange or 
     listed for trading on the NASDAQ system, the current market value shall 
     be the last reported sale price of the Common Stock on such exchange or 
     system on the last business day prior to the date of exercise of this 
     Option or if no such sale is made on such day, the average closing bid 
     and asked prices for such day on such exchange or system; or 

          (2)  If the Common Stock is not so listed or admitted to unlisted 
     trading privileges, the current market value shall be the mean of the 
     last reported bid and asked prices reported by the National Quotation 
     Bureau, Inc. on the last business day prior to the date of the exercise 
     of this Option; or

          (3)  If the Common Stock is not so listed or admitted to unlisted 
     trading privileges and bid and asked prices are not so reported, the 
     current market value shall be an amount not less than the book value 
     thereof at the end of the most recent fiscal year of the Company ending 
     prior to the date of the exercise of the Option, determined in such 
     reasonable manner as may be prescribed by the Board of Directors of the 
     Company.

     (d)  EXCHANGE, TRANSFER, ASSIGNMENT OR LOSS OF OPTION.  This Option is 
exchangeable, without expense, at the option of the Holder, upon presentation 
and surrender hereof to the Company or at the office of its stock transfer 
agent, if any, for other options of different denominations entitling the 
holder thereof to purchase in the aggregate the same number of shares of 
Common Stock purchasable hereunder.  This Option is transferable and may be 
assigned or hypothecated from the date hereof.  Subject to the provisions of 
Section (j), upon surrender of this Option to the Company at its principal 
office or at the office of its stock transfer agent, if any, with the 
Assignment Form annexed hereto duly executed and funds sufficient to pay any 
transfer tax, the Company shall, without charge, execute and deliver a new 
Option in the name of the assignee named in such instrument of assignment and 
this Option shall promptly be canceled.  This Option may be divided or 
combined with other options which carry the same rights upon presentation 
hereof at the principal office of the Company or at the office of its stock 
transfer agent, if any, together with a written notice specifying the names 
and denominations in which new Options are to be issued and signed by the 
Holder hereof.  The term "Option" as used herein includes any Options into 
which this Option may be divided or exchanged.  Upon receipt by the Company 
of evidence satisfactory to it of the loss, theft, destruction or mutilation 
of this Option, and in the case of loss, theft or destruction, of reasonably 


                                     -2-


<PAGE>


satisfactory indemnification and upon surrender and cancellation of this 
Option, if mutilated, the Company will execute and deliver a new Option of 
like tenor and date. 

     (e)  RIGHTS OF THE HOLDER.  The Holder shall not, by virtue hereof, be 
entitled to any rights of a shareholder in the Company, either at law or 
equity, and the rights of the Holder are limited to those expressed in the 
Option and are not enforceable against the Company except to the extent set 
forth herein. Furthermore, Holder by acceptance hereof, consents to and 
agrees to be bound by and to comply with all the provisions of this Option, 
including, without limitation, all the obligations imposed upon the holder 
hereof by Section (j). In addition, the holder of this Option, by accepting 
the same, agrees that the Company and the transfer agent may deem and treat 
the person in whose name this Option is registered as the absolute, true and 
lawful owner for all purposes whatsoever, and neither the Company nor the 
transfer agent shall be affected by any notice to the contrary.

     (f)  ANTI-DILUTION PROVISIONS.  The Exercise Price and the number and 
kind of securities purchasable upon the exercise of this Option shall be 
subject to adjustment from time to time upon the happening of certain events 
as hereinafter provided.  The Exercise Price in effect at any time and the 
number and kind of securities purchasable upon exercise of each Option shall 
be subject to adjustment as follows:

         (1)  In case the Company shall (i) pay a dividend or make a 
      distribution on its shares of Common Stock in shares of Common Stock, 
      (ii) subdivide or reclassify its outstanding Common Stock in shares of 
      Common Stock into a greater number of shares, or (iii) combine or 
      reclassify its outstanding Common Stock into a smaller number of 
      shares, the Exercise Price in effect at the time of the record date for 
      such dividend or distribution or of the effective date of such 
      subdivision, combination or reclassification shall be proportionately 
      adjusted so that the Holder of this Option exercised after such date 
      shall be entitled to receive the aggregate number and kind of shares 
      which, if this Option had been exercised by such Holder immediately 
      prior to such date, he would have owned upon such exercise and been 
      entitled to receive upon such dividend, subdivision, combination or 
      reclassification.  For example, if the Company declares a 2 for 1 stock 
      dividend or stock split and the Exercise Price immediately prior to 
      such event was $10.00 per share, the adjusted Exercise Price 
      immediately after such event would be $5.00 per share.  Such adjustment 
      shall be made successively whenever any event listed above shall occur.

         (2)  Whenever the Exercise Price payable upon exercise of each 
      Option is adjusted pursuant to Subsection (1) above, the number of 
      Shares purchasable upon exercise of this Option shall simultaneously be 
      adjusted by multiplying the number of Shares initially issuable upon 
      exercise of this Option by the Exercise Price in effect on the date 
      hereof and dividing the product so obtained by the Exercise Price, as 
      adjusted.

         (3)  No adjustment in the Exercise Price shall be required unless 
      such adjustment would require an increase or decrease of at least five 
      cents ($0.05) in such price; provided, however, that any adjustments 
      which by reason of this Subsection (3) are 


                                     -3-


<PAGE>


      not required to be made shall be carried forward and taken into account 
      in any subsequent adjustment required to be made hereunder.  All 
      calculations under this Section (f) shall be made to the nearest cent 
      or to the nearest one-hundredth of a share, as the case may be.  
      Anything in this Section (f) to the contrary notwithstanding, the 
      Company shall be entitled, but shall not be required, to make such 
      changes in the Exercise Price, in addition to those required by this 
      Section (f), as it, in its sole discretion, shall determine to be 
      advisable in order that any dividend or distribution in shares of 
      Common Stock, subdivision, reclassification or combination of Common 
      Stock referred to hereinabove in this Section (f) hereafter made by the 
      Company to the holders of its Common Stock shall not result in any tax 
      to the holders of its Common Stock or securities convertible into 
      Common Stock.

         (4)  Whenever the Exercise Price is adjusted, as herein provided, 
      the Company shall promptly cause a notice setting forth the adjusted 
      Exercise Price and adjusted number of Shares issuable upon exercise of 
      each Option to be mailed to the Holder of such Option at the Holder's 
      last address appearing in the Option Register, and shall cause a 
      certified copy thereof to be mailed to its transfer agent, if any.  The 
      Company may retain a firm of independent certified public accountants 
      selected by the Board of Directors (who may be the regular accountants 
      employed by the Company) to make any computation required by this 
      Section (f), and a certificate signed by such firm shall be conclusive 
      evidence of the correctness of such adjustment.

         (5)  In the event that at any time, as a result of an adjustment 
      made pursuant to Subsection (1) above, the Holder of this Option 
      thereafter shall become entitled to receive any shares of the Company, 
      other than Common Stock, thereafter the number of such other shares so 
      receivable upon exercise of this Option shall be subject to adjustment 
      from time to time in a manner and on terms as nearly equivalent as 
      practicable to the provisions with respect to the Common Stock 
      contained in Subsection (1) to (3), inclusive above.

         (6)  Irrespective of any adjustments in the Exercise Price or the 
      number or kind of shares purchasable upon exercise of this Option, 
      Options theretofore or thereafter issued may continue to express the 
      same price and number and kind of shares as are stated in the similar 
      Options initially issuable pursuant to this Agreement.

     (g)  OFFICER'S CERTIFICATE.  Whenever the Exercise Price shall be 
adjusted as required by the provisions of the foregoing Section, the Company 
shall forthwith file in the custody of its Secretary or an Assistant 
Secretary at its principal office and with its stock transfer agent, if any, 
an officer's certificate showing the adjusted Exercise Price determined as 
herein provided, setting forth in reasonable detail the facts requiring such 
adjustment, including a statement of the number of additional shares of 
Common Stock, if any, and such other facts as shall be necessary to show the 
reason for and the manner of computing such adjustment.  Each such officer's 
certificate shall be made available at all reasonable times for inspection by 
the Holder or any holder of a Option executed and delivered pursuant to 
Section (a) and the Company shall, forthwith after each such adjustment, mail 
a copy by certified mail of such certificate to the Holder or any such holder.


                                     -4-

     (h)  NOTICES TO OPTION HOLDERS.  So long as this Option shall be 
outstanding, (i) if Company shall pay any dividend or make any distribution 
upon the Common Stock or (ii) if the Company shall offer to the holders of 
Common Stock for subscription or purchase by them any share of another class 
of capital stock or (iii) if any capital reorganization of the Company, 
reclassification of the capital stock of the Company, consolidation or merger 
of the Company with or into another corporation, sale, lease, or transfer of 
all or substantially all of the property and assets of the Company to another 
corporation, or voluntary or involuntary dissolution, liquidation or winding 
up of the Company shall be effected, then in any such case, the Company shall 
cause to be mailed by certified mail to the Holder, at least fifteen days 
prior the date specified in (x) or (y) below, as the case may be, a notice 
containing a brief description of the proposed action and stating the date on 
which (x) a record is to be taken for the purpose of such dividend, 
distribution or rights, or (y) such reclassification, reorganization, 
consolidation, merger, conveyance, lease, dissolution, liquidation or winding 
up is to take place and the date, if any is to be fixed, as of which the 
holders of Common Stock or other securities shall receive cash or other 
property deliverable upon such reclassification, reorganization, 
consolidation, merger, conveyance, dissolution, liquidation or winding up.

     (i)  RECLASSIFICATION, REORGANIZATION OR MERGER.  In case of any 
reclassification, capital reorganization or other change of outstanding 
shares of Common Stock of the Company, or in case of any consolidation or 
merger of the Company with or into another corporation (other than a merger 
with a subsidiary in which merger the Company is the continuing corporation 
and which does not result in any reclassification, capital reorganization or 
other change of outstanding shares of Common Stock of the class issuable upon 
exercise of this Option) or in case of any sale, lease, or conveyance to 
another corporation of the property of the Company as an entirety, the 
Company shall, as a condition precedent to such transaction, cause effective 
provisions to be made so that the Holder shall have the right thereafter by 
exercising this Option at any time prior to the expiration of the Option, to 
purchase the kind and amount of shares of stock and other securities and 
property receivable upon such reclassification, capital reorganization and 
other change, consolidation, merger, sale, lease or conveyance by a holder of 
the number of shares of Common Stock which might have been purchased upon 
exercise of this Option immediately prior to such reclassification, 
reorganization, change, consolidation, merger, sale, lease or conveyance.  
Any such provision shall include provision for adjustments which shall be as 
nearly equivalent as may be practicable to the adjustments provided for in 
this Option.  The foregoing provisions of this Section (i) shall similarly 
apply to successive reclassifications, capital reorganizations, and changes 
of shares of Common Stock and to successive consolidations, mergers, sales, 
leases or conveyances.  In the event that in connection with any such capital 
reorganization or reclassification, change, consolidation,  merger, sale, 
lease or conveyance, additional shares of Common Stock shall be issued in 
exchange, conversion, substitution, or payment, in whole or in part, for a 
security of the Company other than Common Stock, any such issue shall be 
treated as an issue of Common Stock covered by the provisions of Subsection 
(1) of Section (f) hereof.

     (j)  EXERCISE AND TRANSFER TO COMPLY WITH THE SECURITIES ACT OF 1933.  
The holder of this Option and any transferee hereof, by their acceptance 
hereof, hereby agree that:  (a) the Options being acquired hereunder are 
being purchased for investment purposes 


                                     -5-


<PAGE>


only and not with a view to distribution and will not be transferred without 
the prior written consent of the Company and unless registered or unless 
there is an exemption available from the registration requirements of the 
Securities Act of 1933, as amended, which exemption has been established to 
the satisfaction of the Company; (b) no public distribution of the Options or 
Option Shares will be made in violation of the provisions of the Securities 
Act of  1933, as amended, or the Rules and Regulations promulgated thereunder 
(such Act and Rules and Regulations being hereinafter referred to as the 
"Act") or any applicable state laws; and (c) during such period as delivery 
of a prospectus with respect to the Options or Option Shares may be required 
by the Act, no public distribution of the Options or Option Shares will be 
made in a manner or on terms different from those set forth in, or without 
delivery of, a prospectus then meeting the requirements of Section 10 of the 
Act and in compliance with all applicable state laws.  The holder of this 
Option and any such transferee hereof further agree that if any distribution 
of any of the Options or Option Shares is proposed to be made by them 
otherwise than by delivery of a prospectus meeting the requirements of 
Section 10 of the Act, such action shall be taken only after submission to 
the Company of an opinion of counsel, reasonably satisfactory in form and 
substance to the Company's counsel, to the effect that the proposed 
distribution will not be in violation of the Act or of applicable state law.  
Furthermore, it shall be a condition to the transfer of the Options or Option 
Shares thereof to deliver to the Company his or its written agreement to 
accept and be bound by all of the terms and conditions of this Option.  
Lastly, the holder of this Option has executed and delivered to the Company a 
Stockholder's Representation Agreement containing certain representations and 
warranties of the holder which are incorporated herein by reference.

     (k)  GOVERNING LAW.  This Option is made with reference to the laws of 
the State of California and shall be governed by and construed in accordance 
therewith.

     (l)  ARBITRATION. The parties firmly desire to resolve all disputes 
arising hereunder without resort to litigation in order to protect their 
respective business reputations and the confidential nature of certain 
aspects of their relationship.  Accordingly, any controversy or claim arising 
out of or relating to this Option, or the breach thereof, shall be settled by 
arbitration as set forth below.

          i.   All disputes which in any manner arise out of or relate to 
this Option or the subject matter thereof, shall be resolved exclusively by 
arbitration in accordance with the provisions of this Section (l).  Either 
party may commence arbitration by sending a written demand for arbitration to 
the other party, setting forth the nature of the controversy, the dollar 
amount involved, if any, and the remedies sought, and attaching a copy of 
this Section to the demand.

          ii.  The parties stipulate to arbitration before a single, mutually 
agreed upon arbitrator sitting on the Los Angeles, California Judicial 
Arbitration Mediation Services (JAMS) panel.  In the event that the parties 
are unable to agree upon the person chosen as arbitrator within 30 days of 
the demand for arbitration, the arbitrator shall be selected in the sole 
discretion of the JAMS administrator.  The arbitrator shall be a member of 
the California bar.


                                     -6-


<PAGE>


          iii. The parties shall share all costs of arbitration.  The 
prevailing party shall be entitled to reimbursement by the other party of 
such party's attorneys' fees and costs and any arbitration fees and expenses 
incurred in connection with the arbitration hereunder.

          iv.  The substantive law of the State of California shall be 
applied by the arbitrator.  All proceedings in arbitration shall be in 
accordance with the California Code of Civil Procedure, as amended, and the 
parties shall have the right to legal discovery in any matter submitted to 
arbitration in satisfaction of California Code of Civil Procedure Section 
1283.05, as permitted by California Code of Civil Procedure Section 1283.1(b).

          v.   Arbitration shall take place in Los Angeles, California unless 
the parties otherwise agree.  As soon as reasonably practicable, a hearing 
with respect to the dispute or matter to be resolved shall be conducted by 
the arbitrator.  As soon as reasonably practicable thereafter, the arbitrator 
shall arrive at a final decision, which shall be reduced to writing, signed 
by the arbitrator and mailed to each of the parties and their legal counsel.

          vi.  All decisions of the arbitrator shall be final, binding and 
conclusive on the parties and shall constitute the only method of resolving 
disputes or matters subject to arbitration pursuant to this Option.  The 
arbitrator or a court of appropriate jurisdiction may issue a writ of 
execution to enforce the arbitrator's judgment.  Judgment may be entered upon 
such a decision in accordance with applicable law in any court having 
jurisdiction thereof.

          vii. Notwithstanding the foregoing, because time is of the essence 
of this Option, the parties specifically reserve the right to seek a judicial 
temporary restraining order, preliminary injunction, or other similar 
equitable relief.

          viii.     The decision and award of the arbitrator shall be kept 
confidential by the parties to the greatest extent possible.  No disclosure 
of such decision or award shall be made by the parties except as required by 
law or as necessary or appropriate to effect the enforcement thereof.

          ix.  Should either party institute any action or procedure to 
enforce this Option or any provision hereof, or for damages by reason of any 
alleged breach of this Option or of any provision hereof, or for a 
declaration of rights hereunder (including without limitation arbitration), 
the prevailing party in any such action or proceeding shall be entitled to 
receive from the other party all costs and expenses, including without 
limitation reasonable attorneys' fees, incurred by the prevailing party in 
connection with such action or proceeding.

use of any name, trade secrets, trade names, trademarks, service marks, and
advertising matter, or any property of a similar nature, as it pertains to the
Collateral, in completing production of, advertising for sale, and selling any
Collateral and Debtor's rights under all licenses and all franchise agreements
shall inure to Secured Party's benefit;

               (e)  sell the Collateral at either a public or private sale, or
both, by way of one or more contracts or transactions, for cash or on terms, in
such manner and at such places (including Debtor's premises) as Secured Party
determines is commercially reasonable.  It is not necessary that the Collateral
be present at any such sale;

               (f)  Secured Party shall give notice of the disposition of the
Collateral as follows:

                    (i)       Secured Party shall give Debtor and each holder of
a security interest in the Collateral who has filed with Secured Party a written
request for notice, a notice in writing of the time and place of public sale,
or, if the sale is a private sale or some other disposition other than a public
sale is to be made of the Collateral, then the time on or after which the
private sale or other disposition is to be made;

                    (ii)      the notice shall be personally delivered or
mailed, postage prepaid to Debtor, as provided in the Agreement and Plan of
Reorganization, at least 5 days before the date fixed for the sale, or at least

is to be made; no notice needs to be given prior to the disposition of any
portion of the Collateral that is perishable or threatens to decline speedily in
value or that is of a customarily sold on a recognized market.  Notice to
persons other than Debtor claiming an interest in the Collateral shall be sent
to such addresses as they have furnished to Secured Party;

                    (iii)     if the sale is to be a public sale, Secured Party
also shall give notice of the time and place by publishing a notice one time at
least 5 days before the date of the sale in a newspaper of general circulation
in the county in which the sale is to be held;

               (g)  Secured Party may credit bid and purchase at any public

               (h)  any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Debtor.  Any excess
will be returned, without interest and subject to the rights of third persons,
by Secured Party to Debtor.

          9.2  Upon the exercise by Secured Party of any power, right,
privilege, or remedy pursuant to this Security Agreement which requires any
consent, approval, registration, qualification, or authorization of any
governmental authority, Debtor agrees to execute and deliver, or will cause the
execution and delivery of, all applications, certificates, instruments,
assignments, and other documents and papers that Secured Party or any purchaser
of the Collateral may be required to obtain for such governmental consent,
approval, registration, qualification, or authorization.

          9.3  The rights and remedies of Secured Party under this Security
Agreement, the Promissory Note, and all other agreements contemplated hereby and
thereby shall be cumulative.  Secured Party shall have all other rights and
remedies not inconsistent herewith as provided under the UCC, by law, or in
equity.  No exercise by Secured Party of any one right or remedy shall be deemed
an election of remedies, and no waiver by Secured Party of any default on
Debtor's part shall be deemed a continuing waiver of any further defaults.  No
delay by Secured Party shall constitute a waiver, election or acquiescence with
respect to any right or remedy.

     10.  SECURED PARTY NOT LIABLE.  So long as Secured Party complies with the
obligations, if any, imposed by Section 9207 of the Code, Secured Party shall
not otherwise be liable or responsible in any way or manner for:  (a) the
safekeeping of the Collateral; (b) any loss or damage thereto occurring or
arising in any manner or fashion or from any cause; (c) any diminution in the
value thereof; or (d) any act or default of any carrier, warehouseman, bailee,
forwarding agency, or other person whomsoever.

     11.  INDEFEASIBLE PAYMENT.  The Secured Obligations shall not be considered
indefeasibly paid for purposes of this Security Agreement unless and until all
payments to Secured Party under the Promissory Notes are no longer subject to
any right on the part of any person, including Debtor as a debtor in possession,
or any trustee (whether appointed under the Bankruptcy Code or otherwise) of
Debtor or Debtor's assets to invalidate or set aside such payments or to seek to
recoup the amount of such payments or any portion thereof, or to declare same to
be fraudulent or preferential.  In the event that, for any reason, any portion
of such payments to Secured Party is set aside or restored, whether voluntarily
or involuntarily, after the making thereof, then the obligation intended to be
satisfied thereby shall be revived and continued in full force and effect as if
said payment or payments had not been made.

     12.  NOTICES.  All notices or demands by any party hereto to the other
party and relating to this Security Agreement shall be made in the manner and to
the addresses set forth in the Agreement and Plan of Reorganization.

     15.  ARBITRATION.

     The parties firmly desire to resolve all disputes arising hereunder without
resort to litigation in order to protect their respective business reputations
and the confidential nature of certain aspects of their relationship.
Accordingly, any controversy or claim arising out of or relating to this
Agreement, or the breach thereof, shall be settled by arbitration as set forth
below.

          (a)  All disputes which in any manner arise out of or relate to this
Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the provisions of this Section 15.  Either party
may commence arbitration by sending a written demand for arbitration to the
other party, setting forth the nature of the controversy, the dollar amount
involved, if any, and the remedies sought, and attaching a copy of this Section
to the demand.

          (b)  The parties stipulate to arbitration before a single, mutually
agreed upon arbitrator sitting on the Los Angeles, California Judicial
Arbitration Mediation Services (JAMS) panel.  In the event that the parties are
unable to agree upon the person chosen as arbitrator within 30 days of the
demand for arbitration, the arbitrator shall be selected in the sole discretion
of the JAMS administrator.  The arbitrator shall be a member of the California
bar.

          (c) The parties shall share all costs of arbitration.  The 
prevailing party shall be entitled to reimbursement by the other party of 
such party's attorneys' fees and costs and any arbitration fees and expenses 
incurred in connection with the arbitration hereunder.

          (d) The substantive law of the State of California shall be applied 
by the arbitrator.  All proceedings in arbitration shall be in accordance 
with the California Code of Civil Procedure, as amended, and the parties 
shall have the right to legal discovery in any matter submitted to 
arbitration in satisfaction of California Code of Civil Procedure Section 
1283.05, as permitted by California Code of Civil Procedure Section 1283.1(b).

          (e)  Arbitration shall take place in Los Angeles, California unless
the parties otherwise agree.  As soon as reasonably practicable, a hearing with
respect to the dispute or matter to be resolved shall be conducted by the
arbitrator.  As soon as reasonably practicable thereunder, the arbitrator shall
arrive at a final decision, which shall be reduced to writing, signed by the
arbitrator and mailed to each of the parties and their legal counsel.

          (f)  All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement.  The
arbitrator or a court of appropriate jurisdiction may issue a write of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

          (g)  Notwithstanding the foregoing, because time is of the essence of
this Agreement, the parties specifically reserve the right to a judicial
temporary restraining order, preliminary injunction, or other similar equitable
relief.


                                          17
<PAGE>

          (h)  The decision and award of the arbitrator shall be kept
confidential by the parties to the greatest extent possible.  No disclosure of
such decision or award shall be made by the parties except as required by law or
as necessary or appropriate to effect the enforcement thereof.

          (i)  Should either party institute any action or procedure to enforce
this Agreement or any provision hereof, or for damages by reason of any alleged
breach of this Agreement or of any provision hereof, or for a declaration of
rights hereunder (including, without limitation, arbitration), the prevailing
party in any such action or proceeding shall be entitled to receive from the
other party all costs and expenses, including, without limitation, reasonable
attorneys' fees, incurred by the prevailing party in connection with such action
or proceeding.

     IN WITNESS WHEREOF, the parties have executed this Security Agreement as of
the date first set forth above.

                                                              September 25, 1997


          1.   FOR VALUE RECEIVED, PROSPECT MEDICAL SYSTEMS, INC., a Delaware
corporation ("MAKER"), promises to pay to the order of PROSPECT MEDICAL
HOLDINGS, INC., a Delaware corporation ("PAYEE"), on or before the Maturity Date
unless sooner accelerated in accordance with the terms hereof, the principal sum
of Five Million Dollars ($5,000,000), or such lesser sum as shall equal the
aggregate outstanding principal amount of the loans made by Payee to Maker
hereunder.  As used herein the term "MATURITY DATE" has the meaning given to
such term in that certain Revolving Credit Agreement, dated as of July 3, 1997,
between Payee and Imperial Bank (as amended or restated from time to time, the
"CREDIT AGREEMENT").

          2.   This Secured Promissory Note shall bear interest at a per annum
rate equal to six percent (6%).  All computations of interest shall be
calculated on the basis of a year of three hundred sixty-five (365) days for the
actual days elapsed.  Interest shall accrue from the date of this Secured
Promissory Note to the date of repayment of this Secured Promissory Note in
accordance with the provisions hereof.  Maker shall pay all accrued but unpaid
interest on the principal balance hereof, in arrears, on the first day of each
and every month.

          3.   Maker hereby authorizes Payee to record in its books and records
the date and amount of the loans made by Payee to Maker hereunder, and of each
payment of principal made by Maker, and Maker agrees that all such notations
shall, in the absence of manifest error, be conclusive as to the matters so
noted; PROVIDED, HOWEVER, any failure by Payee to make such notation with
respect to any loan or payment thereof shall not limit or otherwise affect
Maker's obligations under the Secured Promissory Note.

          4.   Maker shall make all payments hereunder in lawful money of the
United States of America and in immediately available funds to the holder hereof
("HOLDER") at Holder's office or to such other address as Holder may from time
to time specify by notice to Maker.

          5.   In no event shall the interest rate and other charges 
hereunder exceed the highest rate permissible under any law which a court of 
competent jurisdiction shall, in a final determination, deem applicable 
hereto.  In the event that such a court determines that Holder has received 
interest and other charges hereunder in excess of the highest rate applicable 
hereto, such excess shall be deemed received on account of, and shall 
automatically be applied to reduce, the principal balance hereof, and the 
provisions hereof shall be 

                                          1
<PAGE>

deemed amended to provide for the highest permissible rate.  If there is no 
principal balance outstanding, Holder shall refund to Maker such excess.

          6.   The unpaid principal balance hereof together with all accrued but
unpaid interest thereon shall be all due and payable upon (i) failure by Maker
to pay any installment of principal or interest due hereunder when due,
(ii) commencement of any proceeding by or against Maker under any bankruptcy or
insolvency laws, or (iii) the occurrence of an "Event of Default" under the
Credit Agreement.

          7.   This Secured Promissory Note is secured by that certain Security
Agreement, dated as of event date herewith, between Maker and Payee.

          8.   Maker hereby waives presentment for payment, notice of dishonor,
protest and notice of protest.

          9.   This Secured Promissory Note shall be governed by and construed
in accordance with the internal laws of the State of California without regard
to principles of conflicts of laws.

          IN WITNESS WHEREOF, Maker has duly executed this Secured Promissory
Note as of the date first above written.

                           (PROSPECT MEDICAL SYSTEMS, INC.)


          This AMENDMENT NUMBER ONE TO INTER-COMPANY SECURITY AGREEMENT, dated
as of September 25, 1997 (this "AMENDMENT"), is entered into between PROSPECT
MEDICAL SYSTEMS, INC., a Delaware corporation ("DEBTOR"), and PROSPECT MEDICAL
HOLDINGS, INC., a Delaware corporation ("SECURED PARTY"), with reference to the
following facts:

                                   R E C I T A L S

          A.   Debtor and Secured Party have previously entered into that
certain Security Agreement, dated as of July 14, 1997 (the "SECURITY
AGREEMENT"), in order to secure obligations owing by Debtor to Secured Party
under a Secured Promissory Note, dated as of even date with the Security
Agreement;

          B.   Debtor is issuing to Secured Party a second Secured Promissory
Note in the principal amount of Five Million Dollars ($5,000,000), dated as of
even date herewith (the "NOTE TWO)"; and

          B.   Debtor and Secured Party are entering into this Amendment in
order to secure the payment of Note Two and all other obligations of Debtor
owing to Secured Party by the Security Agreement.

                                  A G R E E M E N T

          1.   AMENDMENT TO SECTION 1.1.  The definition of "SECURED
OBLIGATIONS" set forth in Section 1.1 of the Security Agreement is hereby
amended in its entirety as follows:

                         "SECURED OBLIGATIONS" shall mean any and all debts,
          liabilities, obligations, or undertakings owing by Debtor to Secured
          Party, whether direct or indirect, absolute or contingent, matured or
          unmatured, due or to become due, voluntary or involuntary, whether now
          existing or hereafter arising, and including all interest not paid
          when due and all Secured Party Expenses which Debtor is required to
          pay or reimburse pursuant to this Security Agreement, the other Loan
          Documents or by law.  Without limiting the generality of the
          foregoing, the Secured Obligations include, without limitation, all

               payment required under any Secured Obligation when due, whether
               for principal, interest, or otherwise, shall constitute an Event
               of Default under this Security Agreement.

          3.   EFFECTIVENESS.  The effectiveness of this Amendment is subject to
and contingent upon the execution and delivery of this Amendment by Debtor and
Secured Party.

          4.   COUNTERPARTS.  This Amendment may be signed in any number of

          5.   AFFIRMATION.  The Security Agreement as amended hereby, and all
other agreements, instruments and documents executed between Debtor and Secured
Party, or by Debtor in favor of Secured Party, remain in full force and effect.

          IN WITNESS WHEREOF, the parties have executed this Amendment as of the
date first set forth above.

                                 CONTINUING GUARANTY


          This CONTINUING GUARANTY (this "GUARANTY"), dated as of September 25,
1997, is executed and delivered by SIERRA MEDICAL MANAGEMENT, INC., a Delaware
corporation ("GUARANTOR"), with reference to the following facts:

                                   R E C I T A L S

          A.   Prospect Medical Holdings, Inc., a Delaware corporation
("BORROWER"), and Imperial Bank, a California banking corporation ("BANK"), have
entered into that certain Revolving Credit Agreement, dated as of July 3, 1997
(as the same may be amended, restated, supplemented or otherwise modified from
time to time, the "LOAN AGREEMENT").

          B.   Guarantor is materially interested in the financial success of
Borrower, agrees that the Loan Agreement is in Borrower's best interests, and
acknowledges that the execution and delivery of this Guaranty formed a material
part of the consideration to Bank to induce Bank to enter into the Loan
Agreement.

                                  A G R E E M E N T

          NOW, THEREFORE, in consideration of the foregoing, Guarantor hereby
agrees, in favor of Bank, as follows:

          1.   DEFINITIONS AND CONSTRUCTION.

               (a)  DEFINITIONS.  All initially capitalized terms used but not
defined herein shall have the meanings assigned to such terms in the Loan
Agreement.  In addition, the following terms, as used in this Guaranty, shall
have the following meanings:

                    "GUARANTEED OBLIGATIONS" means any and all obligations,
indebtedness, or liabilities of any kind or character owed by Borrower to Bank
(including without limitation, all principal and interest owing under the Loans,
all Bank Expenses, the Fees, any other fees and expenses due under the Loan
Agreement, and all other indebtedness evidenced by the Loan Agreement and the
other Loan Documents), including all such obligations, indebtedness, or
liabilities, whether for principal, interest (including any interest which, but
for the application of the provisions of the Bankruptcy Code, would have accrued
on such amounts), premium, reimbursement obligations, fees, costs, expenses
(including, attorneys' fees and attorneys' fees incurred pursuant to proceedings
arising under the Bankruptcy Code), or indemnity obligations, whether
heretofore, now, or hereafter made, incurred, or created, whether voluntarily or
involuntarily made, incurred, or created, whether secured or unsecured (and if
secured, regardless of the nature or extent of the security), whether absolute
or contingent, liquidated or unliquidated, determined or indeterminate, whether
Borrower is liable individually or jointly with others, and whether

                                          1
<PAGE>

recovery is or hereafter becomes barred by any statute of limitations or
otherwise becomes unenforceable for any reason whatsoever, including any act or
failure to act by Bank.

                    "LOAN DOCUMENTS" shall mean the Loan Agreement, this
Guaranty, and the other Loan Documents (as defined in the Loan Agreement).

               (b)  CONSTRUCTION.  Unless the context of this Guaranty clearly
requires otherwise, references to the plural include the singular, references to
the singular include the plural, and the term "including" is not limiting.  The
words "hereof," "herein," "hereby," "hereunder," and other similar terms refer
to this Guaranty as a whole and not to any particular provision of this
Guaranty.  Any reference herein to any of the Loan Documents includes any and
all alterations, amendments, extensions, modifications, renewals, or supplements
thereto or thereof, as applicable.  Neither this Guaranty nor any uncertainty or
ambiguity herein shall be construed or resolved against Bank or Guarantor,
whether under any rule of construction or otherwise.  On the contrary, this
Guaranty has been reviewed by Guarantor, Bank, and their respective counsel, and
shall be construed and interpreted according to the ordinary meaning of the
words used so as to fairly accomplish the purposes and intentions of Bank and
Guarantor.

          2.   GUARANTEED OBLIGATIONS.  Guarantor hereby irrevocably and
unconditionally guarantees to Bank, as and for Guarantor's own debt, until final
and indefeasible payment thereof has been made, (a) payment of the Guaranteed
Obligations, in each case when and as the same shall become due and payable,
whether at maturity, pursuant to a mandatory prepayment requirement, by
acceleration, or otherwise; it being the intent of Guarantor that the guaranty
set forth herein shall be a guaranty of payment and not a guaranty of
collection, and (b) the punctual and faithful performance, keeping, observance,
and fulfillment by Borrower of all of the agreements, conditions, covenants, and
obligations of Borrower contained in the Loan Documents.

          3.   CONTINUING GUARANTY.  This Guaranty includes Guaranteed
Obligations arising under successive transactions continuing, compromising,
extending, increasing, modifying, releasing, or renewing the Guaranteed
Obligations, changing the interest rate, payment terms, or other terms and
conditions thereof, or creating new or additional Guaranteed Obligations after
prior Guaranteed Obligations have been satisfied in whole or in part.  To the
maximum extent permitted by law, Guarantor hereby waives and agrees not to
assert any right Guarantor has under Section 2815 of the California Civil Code,
or otherwise, to revoke this Guaranty as to future indebtedness.

          4.   PERFORMANCE UNDER THIS GUARANTY.  In the event that Borrower
fails to make any payment of any Guaranteed Obligations on or before the due
date thereof, or if Borrower shall fail to perform, keep, observe, or fulfill
any other obligation referred to in clause (b) of Section 2 hereof in the manner
provided in the Loan Documents, Guarantor immediately shall cause such payment
to be made or each of such obligations to be performed, kept, observed, or
fulfilled.

                                          2
<PAGE>

          5.   PRIMARY OBLIGATIONS.  This Guaranty is a primary and original
obligation of Guarantor, is not merely the creation of a surety relationship,
and is an absolute, unconditional, and continuing guaranty of payment and
performance which shall remain in full force and effect without respect to
future changes in conditions, including any change of law or any invalidity or
irregularity with respect to the Loan Documents.  Guarantor agrees that
Guarantor is severally and not jointly and severally liable, with any other
guarantor of the Guaranteed Obligations, to Bank, to the extent set forth in
Section 2 hereof, that the obligations of Guarantor hereunder are independent of
the obligations of Borrower or any other guarantor, and that a separate action
may be brought against Guarantor whether such action is brought against Borrower
or any other guarantor or whether Borrower or any such other guarantor is joined
in such action.  Guarantor agrees that Guarantor's liability hereunder shall be
immediate and shall not be contingent upon the exercise or enforcement by Bank
of whatever remedies it may have against Borrower or any other guarantor, or the
enforcement of any lien or realization upon any security Bank may at any time
possess.  Guarantor agrees that any release which may be given by Bank to
Borrower or any other guarantor shall not release Guarantor.  Guarantor consents
and agrees that Bank shall be under no obligation to marshal any assets of
Borrower or any other guarantor in favor of Guarantor, or against or in payment
of any or all of the Guaranteed Obligations.

          6.   WAIVERS.

               (a)  Guarantor absolutely, unconditionally, knowingly, and
expressly waives:

                    (i)   (1) notice of acceptance hereof; (2) notice of any
loans or other financial accommodations made or extended under the Loan
Documents or the creation or existence of any Guaranteed Obligations; (3) notice
of the amount of the Guaranteed Obligations, subject, however, to Guarantor's
right to make inquiry of Bank to ascertain the amount of the Guaranteed
Obligations at any reasonable time; (4) notice of any adverse change in the
financial condition of Borrower or of any other fact that might increase
Guarantor's risk hereunder; (5) notice of presentment for payment, demand,
protest, and notice thereof as to any instruments among the Loan Documents;
(6) notice of any Unmatured Event of Default or Event of Default; and (7) all
other notices (except if such notice is specifically required to be given to
Guarantor hereunder or under the Loan Documents) and demands to which Guarantor
might otherwise be entitled.

                    (ii)  its right, under Sections 2845 or 2850 of the
California Civil Code, or otherwise, to require Bank to institute suit against,
or to exhaust any rights and remedies which Bank has or may have against,
Borrower or any third party, or against any collateral for the Guaranteed
Obligations provided by Borrower or any third party.  In this regard, Guarantor
agrees that Guarantor is bound to the payment of all Guaranteed Obligations,
whether now existing or hereafter accruing, as fully as if such Guaranteed
Obligations were directly owing to Bank by Guarantor.  Guarantor further waives
any defense arising by reason of any disability or other defense (other than the
defense that the

                                          3
<PAGE>

Guaranteed Obligations shall have been fully and finally performed and
indefeasibly paid) of Borrower or by reason of the cessation from any cause
whatsoever of the liability of Borrower in respect thereof.

                    (iii) (1) any rights to assert against Bank any defense
(legal or equitable), set-off, counterclaim, or claim which Guarantor may now or
at any time hereafter have against Borrower or any other party liable to Bank;
(2) any defense, set-off, counterclaim, or claim, of any kind or nature, arising
directly or indirectly from the present or future lack of perfection,
sufficiency, validity, or enforceability of the Guaranteed Obligations or any
security therefor; (3) any defense Guarantor has to performance hereunder, and
any right Guarantor has to be exonerated, provided by Sections 2819, 2822, or
2825 of the California Civil Code, or otherwise, arising by reason of:  the
impairment or suspension of Bank's rights or remedies against Borrower; the
alteration by Bank of the Guaranteed Obligations; any discharge of Borrower's
obligations to Bank by operation of law as a result of Bank's intervention or
omission; or the acceptance by Bank of anything in partial satisfaction of the
Guaranteed Obligations; (4) the benefit of any statute of limitations affecting
Guarantor's liability hereunder or the enforcement thereof, and any act which
shall defer or delay the operation of any statute of limitations applicable to
the Guaranteed Obligations shall similarly operate to defer or delay the
operation of such statute of limitations applicable to Guarantor's liability
hereunder.

               (b)  Guarantor absolutely, unconditionally, knowingly, and
expressly waives any defense arising by reason of or deriving from (i) any claim
or defense based upon an election of remedies by Bank including any defense
based upon an election of remedies by Bank under the provisions of
Sections 580a, 580b, 580d, and 726 of the California Code of Civil Procedure or
any similar law of California or any other jurisdiction; or (ii) any election by
Bank under Bankruptcy Code Section 1111(b) to limit the amount of, or any
collateral securing, its claim against Borrower.  Pursuant to Section 2856 of
the California Civil Code:

               Guarantor waives all rights and defenses arising out of an
election of remedies by the creditor, even though that election of remedies,
such as a nonjudicial foreclosure with respect to security for a guaranteed
obligation, has destroyed Guarantor's rights of subrogation and reimbursement
against Borrower by the operation of Section 580(d) of the California Code of
Civil Procedure or otherwise.

               Guarantor waives all rights and defenses that Guarantor may have
because Borrower's Obligations are secured by real property.  This means, among
other things:

               (1)  Bank may collect from Guarantor without first foreclosing on
any real or personal property collateral pledged by Borrower.

               (2)  If Bank forecloses on any real property collateral pledged
by Borrower:

                                          4
<PAGE>

                    (A)  The amount of the Guaranteed Obligations may be reduced
only by the price for which that collateral is sold at the foreclosure sale,
even if the collateral is worth more than the sale price.

                    (B)  Bank may collect from Guarantor even if Bank, by
foreclosing on the real property collateral, has destroyed any right Guarantor
may have to collect from Borrower.

               This is an unconditional and irrevocable waiver of any rights and
defenses Guarantor may have because Borrower's Obligations are secured by real
property.  These rights and defenses include, but are not limited to, any rights
or defenses based upon Section 580a, 580b, 580d, or 726 of the California Code
of Civil Procedure.

If any of the Guaranteed Obligations at any time are secured by a mortgage or
deed of trust upon real property, Bank may elect, in its sole discretion, upon a
default with respect to the Guaranteed Obligations, to foreclose such mortgage
or deed of trust judicially or nonjudicially in any manner permitted by law,
before or after enforcing the Loan Documents, without diminishing or affecting
the liability of Guarantor hereunder except to the extent the Guaranteed
Obligations are repaid with the proceeds of such foreclosure.  Guarantor
understands that (a) by virtue of the operation of California's antideficiency
law applicable to nonjudicial foreclosures, an election by Bank nonjudicially to
foreclose such a mortgage or deed of trust probably would have the effect of
impairing or destroying rights of subrogation, reimbursement, contribution, or
indemnity of Guarantor against Borrower or other guarantors or sureties, and
(b) absent the waiver given by Guarantor, such an election would prevent Bank
from enforcing the Loan Documents against Guarantor.  Understanding the
foregoing, and understanding that Guarantor is hereby relinquishing a defense to
the enforceability of the Loan Documents, Guarantor hereby waives any right to
assert against Bank any defense to the enforcement of the Loan Documents,
whether denominated "estoppel" or otherwise, based on or arising from an
election by Bank nonjudicially to foreclose any such mortgage or deed of trust.
Guarantor understands that the effect of the foregoing waiver may be that
Guarantor may have liability hereunder for amounts with respect to which
Guarantor may be left without rights of subrogation, reimbursement,
contribution, or indemnity against Borrower or other guarantors or sureties.
Guarantor also agrees that the "fair market value" provisions of Section 580a of
the California Code of Civil Procedure shall have no applicability with respect
to the determination of Guarantor's liability under the Loan Documents.

               (c)  Guarantor hereby absolutely, unconditionally, knowingly, and
expressly waives:  (i) any right of subrogation Guarantor has or may have as
against Borrower with respect to the Guaranteed Obligations; (ii) any right to
proceed against Borrower or any other person or entity, now or hereafter, for
contribution, indemnity, reimbursement, or any other suretyship rights and
claims, whether direct or indirect, liquidated or contingent, whether arising
under express or implied contract or by operation of law, which Guarantor may
now have or hereafter have as against Borrower with respect

                                          5
<PAGE>

to the Guaranteed Obligations; and (iii) any right to proceed or seek recourse
against or with respect to any property or asset of Borrower.

               (d)  WITHOUT LIMITING THE GENERALITY OF ANY OTHER WAIVER OR OTHER
PROVISION SET FORTH IN THIS GUARANTY, GUARANTOR HEREBY ABSOLUTELY, KNOWINGLY,
UNCONDITIONALLY, AND EXPRESSLY WAIVES AND AGREES NOT TO ASSERT ANY AND ALL

          7.   RELEASES.  Guarantor consents and agrees that, without notice to
or by Guarantor, and without affecting or impairing the obligations of Guarantor
hereunder, Bank may, by action or inaction:

               (a)  compromise, settle, extend the duration or the time for the
                    payment of, or discharge the performance of, or may refuse
                    to or otherwise not enforce this Guaranty, the other Loan
                    Documents, or any part thereof, with respect to Borrower or
                    any other Person;

               (b)  release Borrower or any other Person or grant other
                    indulgences to Borrower or any other Person in respect
                    thereof;

               (c)  amend or modify in any manner and at any time (or from time
                    to time) any of the Loan Documents; or

               (d)  release or substitute any other guarantor, if any, of the
                    Guaranteed Obligations, or enforce, exchange, release, or
                    waive any security for the Guaranteed Obligations or any
                    other guaranty of the Guaranteed Obligations, or any portion
                    thereof.

          8.   NO ELECTION.  Bank shall have all of the rights to seek recourse
against Guarantor to the fullest extent provided for herein, and no election by
Bank to proceed in one form of action or proceeding, or against any party, or on
any obligation, shall constitute a waiver of Bank's right to proceed in any
other form of action or proceeding or against other parties unless Bank has
expressly waived such right in writing.  Specifically, but without limiting the
generality of the foregoing, no action or proceeding by Bank under any document
or instrument evidencing the Guaranteed Obligations shall serve to diminish the

                                          6
<PAGE>

liability of Guarantor under this Guaranty except to the extent that Bank
finally and unconditionally shall have realized indefeasible payment by such
action or proceeding.

          9.   INDEFEASIBLE PAYMENT.  The Guaranteed Obligations shall not be
considered indefeasibly paid for purposes of this Guaranty unless and until all
payments to Bank are no longer subject to any right on the part of any Person,
including Borrower, Borrower as a debtor in possession, or any trustee (whether
appointed under the Bankruptcy Code or otherwise) of any of Borrower's assets,
to invalidate or set aside such payments or to seek to recoup the amount of such
payments or any portion thereof, or to declare same to be fraudulent or
preferential.  Upon such full and final performance and indefeasible payment of
the Guaranteed Obligations, whether by Borrower pursuant to the Loan Agreement
or by any other Person, Bank shall have no obligation whatsoever to transfer or
assign its interests in the Loan Documents to Guarantor.  In the event that, for
any reason, any portion of such payments to Bank is set aside or restored,
whether voluntarily or involuntarily, after the making thereof, then the
obligation intended to be satisfied thereby shall be revived and continued in
full force and effect as if said payment or payments had not been made, and
Guarantor shall be liable for the full amount Bank is required to repay plus any
and all costs and expenses (including attorneys' fees and expenses and
attorneys' fees and expenses incurred pursuant to proceedings arising under the
Bankruptcy Code) paid by Bank in connection therewith.

          10.  FINANCIAL CONDITION OF BORROWER.  Guarantor represents and
warrants to Bank that Guarantor is currently informed of the financial condition
of Borrower and of all other circumstances which a diligent inquiry would reveal
and which bear upon the risk of nonpayment of the Guaranteed Obligations.
Guarantor further represents and warrants to Bank that Guarantor has read and
understands the terms and conditions of the Loan Documents.  Guarantor hereby
covenants that Guarantor will continue to keep informed of Borrower's financial
condition, the financial condition of other guarantors, if any, and of all other
circumstances which bear upon the risk of nonpayment or nonperformance of the
Guaranteed Obligations.

          11.  SUBORDINATION.  Guarantor hereby agrees that any and all present
and future indebtedness of Borrower owing to Guarantor is postponed in favor of
and subordinated to payment, in full, in cash, of the Guaranteed Obligations.
In this regard, no payment of any kind whatsoever shall be made with respect to
such indebtedness until the Guaranteed Obligations have been indefeasibly paid
in full.

          12.  PAYMENTS; APPLICATION.  All payments to be made hereunder by
Guarantor shall be made in lawful money of the United States of America at the
time of payment, shall be made in immediately available funds, and shall be made
without deduction (whether for taxes or otherwise) or offset.  All payments made
by Guarantor hereunder shall be applied as follows: first, to all costs and
expenses (including attorneys' fees and expenses and attorneys' fees and
expenses incurred pursuant to proceedings arising under the Bankruptcy Code)
incurred by Bank in enforcing this Guaranty or in collecting the Guaranteed
Obligations; second, to all accrued and unpaid interest, premium, if any, and

                                          7
<PAGE>

fees owing to Bank constituting Guaranteed Obligations; and third, to the
balance of the Guaranteed Obligations.

          13.  REPRESENTATIONS AND WARRANTIES.  Guarantor hereby represents and
warrants to Bank that:

               (a)  Guarantor is a corporation duly organized and existing under
the laws of Delaware and has the power and authority to own its own properties
and assets, and to transact the business in which it is engaged, and is properly
licensed, qualified to do business and in good standing in every jurisdiction
where the conduct of its business requires it to be so qualified.

               (b)  The execution, delivery and performance of this Guaranty are
within Guarantor's powers, are not in conflict with the terms of any charter,
bylaw, [certificate/articles] of incorporation or other organization papers of
Guarantor, and do not result in a breach of or constitute a default under any
contract, obligation, indenture or other instrument to which Guarantor is a
party or by which Guarantor is bound or affected.  There is no law, rule or
regulation, nor is there any judgment, decree or order of any court or
governmental authority binding on Guarantor which would be contravened by the
execution, delivery, performance or enforcement of this Guaranty and the other
Loan Documents to which Guarantor is a party.

               (c)  Guarantor has taken all corporate action necessary to
authorize the execution and delivery of this Guaranty and the other Loan
Documents to which Guarantor is a party, and the consummation of the
transactions contemplated hereby and thereby.  Upon their execution and delivery
in accordance with their respective terms, this Guaranty and the other Loan
Documents to which Guarantor is a party will constitute legal, valid and binding
agreements and obligations of Guarantor enforceable against Guarantor in
accordance with their respective terms, except as enforceability may be limited
by bankruptcy, insolvency, fraudulent conveyance, and similar laws and equitable
principles affecting the enforcement of creditors' rights generally.

               (d)  No approval, consent, exemption or other action by, or
notice to or filing with, any governmental authority is necessary in connection
with the execution, delivery, performance or enforcement of this Guaranty and
the other Loan Documents to which Guarantor is a party except as may have been
obtained by Guarantor and certified copies of which have been delivered to Bank.

               (e)  Guarantor has no Debt other than Debt owing to Bank
hereunder, and Guarantor covenants and agrees that until the indefeasible
payment, performance and satisfaction in full of the Guaranteed Obligations,
Guarantor will not create, incur, assume or suffer to exist any Debt without the
prior written consent of Bank.

          14.  ATTORNEYS' FEES AND COSTS.  Guarantor agrees to pay, on demand,
all attorneys' fees (including attorneys' fees incurred pursuant to proceedings
arising under the

                                          8
<PAGE>

Bankruptcy Code) and all other costs and expenses which may be incurred by Bank
in the enforcement of this Guaranty or in any way arising out of, or
consequential to the protection, assertion, or enforcement of the Guaranteed
Obligations (or any security therefor), whether or not suit is brought.

          15.  NOTICES.  All notices, requests and other communications to any
party hereunder shall be sent in accordance with Section 9.1 of the Loan

          16.  CUMULATIVE REMEDIES.  No remedy under this Guaranty or under any
Loan Document is intended to be exclusive of any other remedy, but each and
every remedy shall be cumulative and in addition to any and every other remedy
given hereunder or under any Loan Document, and those provided by law or in
equity.  No delay or omission by Bank to exercise any right under this Guaranty
shall impair any such right nor be construed to be a waiver thereof.  No failure
on the part of Bank to exercise, and no delay in exercising, any right hereunder
shall operate as a waiver thereof; nor shall any single or partial exercise of
any right hereunder preclude any other or further exercise thereof or the
exercise of any other right.

provision shall not affect the validity, legality or enforceability of any other
provision of this Guaranty.

constitutes the entire agreement between Guarantor and Bank pertaining to the
subject matter contained herein.  Any provision of this Guaranty may be amended

          21.  SUCCESSORS AND ASSIGNS.  This Guaranty shall bind the successors
and assigns of Guarantor, and shall inure to the benefit of the respective
successors and assigns of Bank; PROVIDED, HOWEVER, Guarantor may not assign this
Guaranty or delegate any of his duties hereunder without Bank's prior written
consent and any such prohibited assignment shall be absolutely null and void.
Bank reserves its right to sell, assign, transfer, negotiate, or grant
participations in all or any part of, or any interest in, the rights and
benefits hereunder pursuant to and in accordance with the provisions of the Loan
Documents.  In connection therewith, Bank may disclose all documents and

enforcement hereof, and the rights of the parties hereto, shall be determined
under, governed by, and construed in accordance with the internal laws of the
State of California, without regard to principles of conflicts of law.

          23.  JUDICIAL REFERENCE.

               (a)  Other than (i) nonjudicial foreclosure and all matters in
connection therewith regarding security interests in real or personal property;
or (ii) the appointment of a receiver, or the exercise of other provisional
remedies (any and all of which may be initiated pursuant to applicable law),
each controversy, dispute or claim between the parties arising out of or
relating to this Guaranty, which controversy, dispute or claim is not settled in
writing within thirty (30) days after the "CLAIM DATE" (defined as the date on
either Guarantor or Bank gives written notice to the other that a controversy,
dispute or claim exists), will be settled by a reference proceeding in
California in accordance with the provisions of Section 638 ET SEQ. of the
California Code of Civil Procedure, or their successor section ("CCP"), which
shall constitute the exclusive remedy for the settlement of any controversy,
dispute or claim concerning this Guaranty, including whether such controversy,
dispute or claim is subject to the reference proceeding and except as set forth
above, the parties waive their rights to initiate any legal proceedings against
each other in any court or jurisdiction other than the Superior Court in the
County where any real property collateral for this Guaranty is located or Los
Angeles County if none (the "COURT").  The referee shall be a retired Judge of
the Court selected by mutual agreement of the parties, and if they cannot so
agree within forty-five (45) days after the Claim Date, the referee shall be
promptly selected by the Presiding Judge of the Court (or his representative).
The referee shall be appointed to sit as a temporary judge, with all of the
powers for a temporary judge, as authorized by law, and upon selection should
take and subscribe to the oath of office as provided for in Rule 244 of the
California Rules of Court (or any subsequently enacted Rule).  Each party shall

<PAGE>

matter for hearing within sixty (60) days after the date of selection of the
referee and (b) try any and all issues of law or fact and report a statement of
decision upon them, if possible, within ninety (90) days of the Claim Date.  Any
decision rendered by the referee will be final, binding and conclusive and
judgment shall be entered pursuant to CCP Section  644 in any court in the State
of California having jurisdiction.  Any party may apply for a reference
proceeding at any time after thirty (30) days following notice to any other
party of the nature of the controversy, dispute or claim, by filing a petition
for a hearing and/or trial.  All discovery permitted by this Guaranty shall be
completed no later than fifteen (15) days before the first hearing date
established by the referee.  The referee may extend such period in the event of
a party's refusal to provide requested discovery for any reason whatsoever,
including, without limitation, legal objections raised to such discovery or
unavailability of a witness due to absence or illness.  No party shall be
entitled to "priority" in conducting discovery.  Depositions may be taken by
either party upon seven (7) days written notice, and request for production or
inspection of documents shall be responded to within ten (10) days after
service.  All disputes relating to discovery which cannot be resolved by the
parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Superior Court is empowered to issue temporary and/or provisional
remedies, as appropriate.

               (b)  Except as expressly set forth in this Guaranty, the referee
shall determine the manner in which the reference proceeding is conducted
including the time and place of all hearings, the order of presentation of
evidence, and all other questions that arise with respect to the course of the
reference proceeding.  All proceedings and hearings conducted before the
referee, except for trial, shall be conducted without a court reporter except
that when any party so requests, a court reporter will be used at any hearing
conducted before the referee.  The party making such a request shall have the
obligation to arrange for and pay for the court reporter.  The costs of the
court reporter at the trial shall be borne equally by the parties.

               (c)  The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties.  The referee shall issue a single judgment at the
close of the reference proceeding which shall dispose of all of the claims of
the parties that are the subject of the reference.  The parties hereto expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee.  The parties hereto
expressly reserve the right to findings of fact, conclusions of laws, a written
statement of decision, and the right to move for a new trial or a different
judgment, which new trial, if granted, is also to be a reference proceeding
under this provision.

<PAGE>

               (d)  In the event that the enabling legislation which provides
for appointment of a referee is repealed (and no successor statute is enacted),
any dispute between the parties that would otherwise be determined by the
reference procedure herein described will be resolved and determined by
arbitration.  The arbitration will be conducted by a retired judge of the Court,
in accordance with the California Arbitration Act, Section  1280 through Section
1294.2 of the CCP as amended from time to time.  The limitations with respect
to discovery as set forth hereinabove shall apply to any such arbitration
proceeding.

          8.   EVENTS OF DEFAULT.  The occurrence of any Event of Default under
the Loan Agreement shall constitute an event of default ("Event of Default")
under this Security Agreement.

          9.   RIGHTS AND REMEDIES.

               9.1  During the continuance of an Event of Default, Bank, without
notice or demand, may do any one or more of the following, all of which are
authorized by Guarantor:

                    (a)  Settle or adjust disputes and claims directly with
Account Debtors for amounts and upon terms which Bank considers advisable, and
in such cases, Bank will credit the Secured Obligations with only the net
amounts received by Bank in payment of such disputed Accounts after deducting
all Bank Expenses incurred or expended in connection therewith;

                    (b)  Cause Guarantor to hold all returned Inventory in trust
for Bank, segregate all returned Inventory from all other property of Guarantor
or in Guarantor's possession and conspicuously label said returned Inventory as
the property of Bank;

                    (c)  Without notice to or demand upon Guarantor or any
guarantor, make such payments and do such acts as Bank considers necessary or
reasonable to protect its security interests in the Collateral.  Guarantor
agrees to assemble the Collateral if Bank so requires, and to make the
Collateral available to Bank as Bank may designate.  Guarantor authorizes Bank
to enter the premises where the Collateral is located, to take and maintain
possession of the Collateral, or any part of it, and to pay, purchase, contest,
or compromise any encumbrance, charge, or Lien that in Bank's determination
appears to conflict with its security interests and to pay all expenses incurred
in connection therewith.  With respect to any of Guarantor's owned or leased
premises, Guarantor hereby grants Bank a license to enter into possession of
such premises and to occupy the same, without charge, for up to 120 days in
order to exercise any of Bank's rights or remedies provided herein, at law, in
equity, or otherwise;

                    (d)  Without notice to Guarantor (such notice being
expressly waived), and without constituting a retention of any collateral in
satisfaction of an obligation (within the meaning of Section 9505 of the Code),
set off and apply to the Secured Obligations any and all (i) balances and
Deposit Accounts of Guarantor held by Bank, or (ii) indebtedness at any time
owing to or for the credit or the account of Guarantor held by Bank;

                    (e)  Hold, as cash collateral, any and all balances and
Deposit Accounts of Guarantor held by Bank, to secure the full and final
repayment of all of the Secured Obligations;


                                          14
<PAGE>

                    (f)  Ship, reclaim, recover, store, finish, maintain,
repair, prepare for sale, advertise for sale, and sell (in the manner provided
for herein) the Collateral.  Bank is hereby granted a license or other right to
use, without charge, Guarantor's labels, patents, copyrights, rights of use of
any name, trade secrets, trade names, trademarks, service marks, and advertising
matter, or any property of a similar nature, as it pertains to the Collateral,
in completing production of, advertising for sale, and selling any Collateral
and Guarantor's rights under all licenses and all franchise agreements shall
inure to Bank's benefit;

                    (g)  Sell the Collateral at either a public or private sale,
or both, by way of one or more contracts or transactions, for cash or on terms,
in such manner and at such places (including Guarantor's premises) as Bank
determines is commercially reasonable.  It is not necessary that the Collateral
be present at any such sale;

                    (h)  Bank shall give notice of the disposition of the
Collateral as follows:

                         (i)    Bank shall give Guarantor and each holder of a
security interest in the Collateral who has filed with Bank a written request
for notice, a notice in writing of the time and place of public sale, or, if the
sale is a private sale or some other disposition other than a public sale is to
be made of the Collateral, then the time on or after which the private sale or
other disposition is to be made;

                         (ii)   The notice shall be personally delivered or
mailed, postage prepaid, to Guarantor as provided in SECTION 15 of the Guaranty,
at least 5 days before the date fixed for the sale, or at least 5 days before
the date on or after which the private sale or other disposition is to be made;
no notice needs to be given prior to the disposition of any portion of the
Collateral that is perishable or threatens to decline speedily in value or that
is of a type customarily sold on a recognized market.  Notice to Persons other
than Guarantor claiming an interest in the Collateral shall be sent to such
addresses as they have furnished to Bank;

                         (iii)  If the sale is to be a public sale, Bank also
shall give notice of the time and place by publishing a notice one time at least
5 days before the date of the sale in a newspaper of general circulation in the
county in which the sale is to be held;

                    (i)  Bank may credit bid and purchase at any public sale;
and

                    (j)  Any deficiency that exists after disposition of the
Collateral as provided above will be paid immediately by Guarantor.  Any excess
will be returned, without interest and subject to the rights of third Persons,
by Bank to Guarantor.


                                          15

               9.2  Upon the exercise by Bank of any power, right, privilege, or
remedy pursuant to this Security Agreement which requires any consent, approval,
registration, qualification, or authorization of any Governmental Authority,
Guarantor agrees to execute and deliver, or will cause the execution and
delivery of, all applications, certificates, instruments, assignments, and other
documents and papers that Bank or any purchaser of the Collateral may be
required to obtain for such governmental consent, approval, registration,
qualification, or authorization.

               9.3  The rights and remedies of Bank under this Security
Agreement, the Guaranty, the other Loan Documents, and all other agreements
contemplated hereby and thereby shall be cumulative.  Bank shall have all other
rights and remedies not inconsistent herewith as provided under the Code, by
law, or in equity.  No exercise by Bank of any one right or remedy shall be
deemed an election of remedies, and no waiver by Bank of any default on
Guarantor's part shall be deemed a continuing waiver of any further defaults.
No delay by Bank shall constitute a waiver, election or acquiescence with
respect to any right or remedy.

          10.  BANK NOT LIABLE.  So long as Bank complies with the obligations,
if any, imposed by Section 9207 of the Code, Bank shall not otherwise be liable
or responsible in any way or manner for:  (a) the safekeeping of the Collateral;
(b) any loss or damage thereto occurring or arising in any manner or fashion or
from any cause; (c) any diminution in the value thereof; or (d) any act or
default of any carrier, warehouseman, bailee, forwarding agency, or other person
whomsoever.

          11.  INDEFEASIBLE PAYMENT.  The Secured Obligations shall not be
considered indefeasibly paid for purposes of this Security Agreement unless and
until all payments to Bank are no longer subject to any right on the part of any
Person, including Guarantor, Guarantor as a debtor in possession, or any trustee
(whether appointed under the Bankruptcy Code or otherwise) of Guarantor or
Guarantor's Assets to invalidate or set aside such payments or to seek to recoup
the amount of such payments or any portion thereof, or to declare same to be
fraudulent or preferential.  In the event that, for any reason, any portion of
such payments to Bank is set aside or restored, whether voluntarily or
involuntarily, after the making thereof, then the obligation intended to be
satisfied thereby shall be revived and continued in full force and effect as if
said payment or payments had not been made.

          12.  NOTICES.  All notices or demands by any party hereto to the other
party and relating to this Security Agreement shall be made in the manner and to
the addresses set forth in Section 15 of the Guaranty.

          13.  GENERAL PROVISIONS.

               13.1 SUCCESSORS AND ASSIGNS.  This Security Agreement shall bind
and inure to the benefit of the respective successors and assigns of Guarantor
and Bank; PROVIDED, HOWEVER, that Guarantor may not assign this Security
Agreement nor delegate any


                                          16
<PAGE>

of its duties hereunder without Bank's prior written consent and any prohibited
assignment or delegation shall be absolutely void.  No consent by Bank to an
assignment by Guarantor shall release Guarantor from the Secured Obligations.
Bank reserves its right to sell, assign, transfer, negotiate, or grant
participations in all or any part of, or any interest in, the rights and
benefits hereunder pursuant to and in accordance with the provisions of the Loan
Agreement.  In connection therewith, Bank may disclose all documents and
information which Bank now or hereafter may have relating to Guarantor,
Guarantor's business, or the Collateral to any such prospective or actual
Transferee, subject to the terms of Section 9.5(e) of the Loan Agreement.

               13.2 EXHIBITS AND SCHEDULES.  All of the exhibits and schedules
attached hereto shall be deemed incorporated by reference.

               13.3 NO PRESUMPTION AGAINST ANY PARTY.  Neither this Security
Agreement nor any uncertainty or ambiguity herein shall be construed or resolved
against Bank or Guarantor, whether under any rule of construction or otherwise.
On the contrary, this Security Agreement has been reviewed by each of the
parties and their counsel and shall be construed and interpreted according to
the ordinary meaning of the words used so as to accomplish fairly the purposes
and intentions of all parties hereto.

               13.4 AMENDMENTS AND WAIVERS.  Any provision of this Agreement or
any of the Loan Documents to which Guarantor is a party may be amended or waived
if, but only if, such amendment or waiver is in writing and is signed by the
party asserted to be bound thereby, and then such amendment or waiver shall be
effective only in the specific instance and specific purpose for which given.

               13.5 COUNTERPARTS; INTEGRATION; EFFECTIVENESS.  This Security
Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument.  This Security Agreement constitutes the entire agreement
and understanding among the parties hereto and supersedes any and all prior
agreements and understandings, oral or written, relating to the subject matter
hereof.  This Security Agreement shall become effective when executed by each of
the parties hereto and delivered to Bank.

               13.6 SEVERABILITY.  The provisions of this Agreement are
severable.  The invalidity, in whole or in part, of any provision of this
Agreement shall not affect the validity or enforceability of any other of its
provisions.  If one or more provisions hereof shall be declared invalid or
unenforceable, the remaining provisions shall remain in full force and effect
and shall be construed in the broadest possible manner to effectuate the
purposes hereof.

          14.  GOVERNING LAW.  This Security Agreement shall be deemed to have
been made in the State of California and the validity, construction,
interpretation, and enforcement hereof, and the rights of the parties hereto,
shall be determined under,


                                          17
<PAGE>

governed by, and construed in accordance with the internal laws of the State of
California, without regard to principles of conflicts of law.

          15.  JUDICIAL REFERENCE.

               15.1 Other than (i) nonjudicial foreclosure and all matters in
connection therewith regarding security interests in real or personal property;
or (ii) the appointment of a receiver, or the exercise of other provisional
remedies (any and all of which may be initiated pursuant to applicable law),
each controversy, dispute or claim between the parties arising out of or
relating to this Security Agreement, which controversy, dispute or claim is not
settled in writing within thirty (30) days after the "Claim Date" (defined as
the date on which Guarantor or Bank gives written notice to the other that a
controversy, dispute or claim exists), will be settled by a reference proceeding
in California in accordance with the provisions of Section 638 ET SEQ. of the
California Code of Civil Procedure, or their successor section ("CCP"), which
shall constitute the exclusive remedy for the settlement of any controversy,
dispute or claim concerning this Security Agreement, including whether such
controversy, dispute or claim is subject to the reference proceeding and except
as set forth above, the parties waive their rights to initiate any legal
proceedings against each other in any court or jurisdiction other than the
Superior Court in the County where any real property Collateral is located or
Los Angeles County if none (the "Court").  The referee shall be a retired Judge
of the Court selected by mutual agreement of the parties, and if they cannot so
agree within forty-five (45) days after the Claim Date, the referee shall be
promptly selected by the Presiding Judge of the Court (or his representative).
The referee shall be appointed to sit as a temporary judge, with all of the
powers for a temporary judge, as authorized by law, and upon selection should
take and subscribe to the oath of office as provided for in Rule 244 of the
California Rules of Court (or any subsequently enacted Rule).  Each party shall
have one peremptory challenge pursuant to CCP Section 170.6.  The referee shall
(a) be requested to set the matter for hearing within sixty (60) days after the
Claim Date and (b) try any and all issues of law or fact and report a statement
of decision upon them, if possible, within ninety (90) days of the Claim Date.
Any decision rendered by the referee will be final, binding and conclusive and
judgment shall be entered pursuant to CCP Section 644 in any court in the State
of California having jurisdiction.  Any party may apply for a reference
proceeding at any time after thirty (30) days following notice to any other
party of the nature of the controversy, dispute or claim, by filing a petition
for a hearing and/or trial.  All discovery permitted by this Security Agreement
shall be completed no later than fifteen (15) days before the first hearing date
established by the referee.  The referee may extend such period in the event of
a party's refusal to provide requested discovery for any reason whatsoever,
including, without limitation, legal objections raised to such discovery or
unavailability of a witness due to absence or illness.  No party shall be
entitled to "priority" in conducting discovery.  Depositions may be taken by
either party upon seven (7) days written notice, and request for production or
inspection of documents shall be responded to within ten (10) days after
service.  All disputes relating to discovery which cannot be resolved by the
parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending


                                          18
<PAGE>

appointment of the referee as provided herein, the Superior Court is empowered
to issue temporary and/or provisional remedies, as appropriate.

               15.2 Except as expressly set forth in this Security Agreement,
the referee shall determine the manner in which the reference proceeding is
conducted including the time and place of all hearings, the order of
presentation of evidence, and all other questions that arise with respect to the
course of the reference proceeding.  All proceedings and hearings conducted
before the referee, except for trial, shall be conducted without a court
reporter except that when any party so requests, a court reporter will be used
at any hearing conducted before the referee.  The party making such a request
shall have the obligation to arrange for and pay for the court reporter.  The
costs of the court reporter at the trial shall be borne equally by the parties.

               15.3 The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties.  The referee shall issue a single judgment at the
close of the reference proceeding which shall dispose of all of the claims of
the parties that are the subject of the reference.  The parties hereto expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee.  The parties hereto
expressly reserve the right to findings of fact, conclusions of laws, a written
statement of decision, and the right to move for a new trial or a different
judgment, which new trial, if granted, is also to be a reference proceeding
under this provision.

               15.4 In the event that the enabling legislation which provides
for appointment of a referee is repealed (and no successor statute is enacted),
any dispute between the parties that would otherwise be determined by the
reference procedure herein described will be resolved and determined by
arbitration.  The arbitration will be conducted by a retired judge of the Court,
in accordance with the California Arbitration Act, Section 1280 through Section
1294.2 of the CCP as amended from time to time.  The limitations with respect to
discovery as set forth hereinabove shall apply to any such arbitration
proceeding.

       B.   Pledgor has agreed to provide additional security for its
obligations under the Loan Agreement by pledging to Pledgee all of Pledgor's
right, title and interest in and to the Collateral (as hereinafter defined), to

       NOW THEREFORE, in consideration of the mutual promises, covenants,
conditions, representations, and warranties hereinafter set forth and for other
good and valuable consideration, the parties hereto mutually agree as follows:

       1.   DEFINITIONS AND CONSTRUCTION.

            (a)  DEFINITIONS.  All initially capitalized terms used but not
defined in this Agreement shall have the meanings ascribed to such terms in the
Loan Agreement.  In addition, the following terms, as used in this Agreement,
have the following meanings:

                 "CERTIFICATED SECURITY, "ENDORSEMENT", "REGISTERED FORM",

               (iii)  The proceeds of each of the foregoing, including any
and all dividends, cash, stock, instruments, and other property from time to

                 "SECURED OBLIGATIONS" means Obligations (as defined in the
Loan Agreement) and the obligations of Pledgor hereunder.

                 "'33 ACT" means the Securities Act of 1933, as amended and
supplemented from time to time, and any successor statute, and any and all rules
promulgated in connection therewith.

            (b)  CONSTRUCTION.  Unless the context of this Agreement clearly
requires otherwise, references to the plural include the singular, references to
the singular include the plural, the part includes the whole, "including" is not
limiting, and "or" has the inclusive meaning represented by the phrase "and/or."
References in this Agreement to "determination" by Pledgee include reasonable
estimates (absent manifest error) by Pledgee, as applicable (in the case of
quantitative determinations) and reasonable beliefs (absent manifest error) by
Pledgee, as applicable (in the case of qualitative determinations).  The words
"hereof," "herein," "hereby," "hereunder," and similar terms in this Agreement
refer to this Agreement as a whole and not to any particular provision of this
Agreement.  Article, section, subsection, exhibit, and schedule references are
to this Agreement unless otherwise specified.

       2.   PLEDGE.  As security for the prompt and complete payment and
performance of the Secured Obligations, Pledgor hereby delivers, pledges, and
grants to Pledgee a continuing security interest in all of Pledgor's now-owned
or hereafter-acquired right, title, and interest in and to the Collateral.

       3.   CONTROL OF COLLATERAL.  Pledgor shall promptly deliver to Pledgee
any and all Certificated Securities comprising all or any portion of the
Collateral for Pledgee to hold pursuant to the terms hereof, and if such
Certificated Securities are in Registered Form, (i) such Certificated Securities
shall be endorsed in blank by an effective undated Endorsement, in form and
substance satisfactory to Pledgee in its sole and absolute discretion, or (ii)
Pledgor shall cause the Company or the Company's transfer agent to


                                          2
<PAGE>

transfer such Securities into the name of Pledgee and issue a replacement
Security Certificate evidencing the same in the name of Pledgee.  In the event
that all or any portion of the Collateral consists of Uncertificated Securities,
Pledgor shall cause the Company to enter into a control agreement with respect
to such Uncertificated Securities, in form and substance satisfactory to Pledgee
in its sole and absolute discretion.

       4.   FURTHER ASSURANCES.  Pledgor agrees that it shall cooperate with
Pledgee and shall execute and deliver, or cause to be executed and delivered, to
Pledgee all stock powers, proxies, assignments, financing statements,
instruments, control agreements and other documents, and shall take all further
action, at the expense of Pledgor, from time to time requested by Pledgee, in
order to maintain a continuing, first-priority, perfected security interest in
the Collateral in favor of Pledgee, and to enable Pledgee to exercise and
enforce its rights and remedies hereunder with respect to the Collateral, and
Pledgor agrees that it shall execute and deliver to Pledgee at Pledgee's request
any further applications, agreements, documents and instruments, and shall
perform any and all acts deemed necessary by Pledgee to carry into effect the
terms, conditions, and provisions of this Agreement and the transactions
connected herewith.  Should Pledgor fail to execute or deliver any such
applications, agreements, documents, financing statements and instruments, or to
perform any such acts, Pledgor acknowledges that Pledgee may execute and deliver
the same and perform such acts in the name of Pledgor and on its behalf as its
attorney-in-fact in accordance with Section 13.

       5.   PLEDGEE'S DUTIES.  Pledgee shall not have any duties with respect
to the Collateral other than the duty to use reasonable care if the Collateral
is in its possession.  In accordance with Section 9207 of the Code, Pledgee
shall be deemed to have used reasonable care if it observes substantially the
same standard of care with respect to the custody or preservation of the
Collateral as it observes with respect to similar assets owned by Pledgee.
Without limiting the generality of the foregoing, Pledgee shall be under no
obligation to take any steps necessary to preserve rights in the Collateral
against any other parties, to sell the same if it threatens to decline in value,
or to exercise any rights represented thereby (including rights with respect to
calls, conversions, exchanges, maturities, or tenders); PROVIDED, HOWEVER, that
Pledgee may, at its option, do so, and any and all expenses incurred in
connection therewith shall be for the account of Pledgor.

       6.   VOTING RIGHTS; DIVIDENDS; ETC.

            6.1  During the term of this Agreement, and as long as no Event
of Default is continuing:

                 (a)  Pledgor shall be entitled to exercise any and all
voting and other consensual rights pertaining to the Shares or any part thereof;
PROVIDED, HOWEVER, no vote shall be cast or any consent, waiver or ratification
given or any action taken which would violate or be inconsistent with the terms
of this Agreement, the Loan Agreement or any other instrument or agreement
referred to therein or herein, or which could have the effect of impairing the
value of the Collateral or any part thereof or the position or interest


                                          3
<PAGE>

of Pledgee therein.

                 (b)  Pledgor shall be entitled to receive and retain any and
all dividends and distributions paid in respect of the Shares not otherwise
prohibited by the Loan Agreement; PROVIDED, HOWEVER, that any and all:

                      (i)  dividends and distributions paid or payable other
than in cash in respect of, and any and all additional Shares or instruments or
other property received, receivable, or otherwise distributed in respect of, or
in exchange for, any Shares;

                     (ii)  dividends and distributions paid or payable in
cash in respect of any Shares in connection with a partial or total liquidation
or dissolution, merger, consolidation of the Company, or any exchange of stock,
conveyance of assets, or similar corporate reorganization; and

                    (iii)  cash paid with respect to, payable, or otherwise
distributed on redemption of, or in exchange for, any Shares,

shall be forthwith delivered to Pledgee to hold as Collateral and shall, if
received by Pledgor, be received in trust for the benefit of Pledgee, be
segregated from the other property or funds of Pledgor, and be forthwith
delivered to Pledgee as Collateral in the same form as so received (with any
necessary endorsement), and, if deemed appropriate by Pledgee, Pledgor shall
take such actions, including the actions described in Section 2, as Pledgee may
require.

            6.2  Upon the occurrence of an Event of Default or if any amounts
shall be due and payable (whether by acceleration, maturity, or otherwise) under
any of the Secured Obligations, all rights of Pledgor to exercise the voting and
other consensual rights that it would otherwise be entitled to exercise pursuant
to Section 6.1(a) and to receive the dividends and distributions that it would
otherwise be authorized to receive and retain pursuant to Section 5.1(b) shall,
at Pledgee's option, cease, and all such rights shall, at Pledgee's option,
thereupon become vested in Pledgee, and Pledgee shall, at its option, thereupon
have the sole right to exercise such voting and other consensual rights and to
receive and hold as Collateral such dividends and interest payments.  Any
payments received by Pledgor contrary to the provisions of this Section 6.2
shall be held in trust by Pledgor for the benefit of Pledgee, shall be
segregated from other funds of Pledgor, and shall be promptly paid over to
Pledgee, with any necessary endorsement.

       7.   REPRESENTATIONS, WARRANTIES, AND COVENANTS.  In order to induce
Pledgee to continue to make Loans to Pledgor, Pledgor hereby warrants,
represents, and covenants that:

            7.1  There are no restrictions upon the transfer of any of the
Collateral to or by Pledgee and Pledgor is the sole beneficial owner of the
Collateral and has the right to pledge and grant a security interest in or
otherwise transfer such Collateral


                                          4
<PAGE>

free of any encumbrances or rights of third Persons.

            7.2  All of the Collateral is and shall remain free from all
Liens except as created hereby.  Pledgor shall not, without Pledgee's prior
written consent, sell or otherwise dispose of any of the Collateral.

            7.3  The execution and delivery of this Agreement, and the
completion of the actions described in Section 3, creates a valid, perfected and
first-priority security interest in the Collateral in favor of Pledgee, and all
actions necessary or desirable to such perfection have been duly taken.

            7.4  No authorization or other action by, and no notice to or
filing with, any Governmental Authority is required either:  (a) for the grant
by Pledgor of the security interest granted hereby or for the execution,
delivery, or performance of this Agreement by Pledgor; (b) for the perfection of
or exercise by Pledgee of its rights and remedies hereunder except as may be
required in connection with a disposition of the Collateral by laws affecting
the offering and sale of securities generally; or (c) for the exercise by
Pledgee of the voting or other rights provided for in this Agreement or the
remedies in respect of the Collateral pursuant to this Agreement except as may
be required in connection with a disposition of the Collateral by laws affecting
the offering and sale of securities generally.

            7.5  The pledge of the Collateral pursuant to this Agreement, and
the making of the loans in accordance with the terms of the Loan Agreement, does
not violate Regulation G, T, U, or X of the Board of Governors of the Federal
Reserve System.

            7.6  The Company presently has issued and outstanding one
thousand (1,000) shares of Common Stock of which one hundred percent (100%) is
owned by Pledgor and they constitute, respectively, all of the capital stock of
Company and the Shares referenced herein.

            7.7  There are no presently existing Options.

            7.8  All of the outstanding Shares have been duly and validly
issued by the Company, and they are fully paid and nonassessable.

            7.9  Pledgor has made its own arrangements for keeping informed
of changes or potential changes affecting the Collateral (including, but not
limited to, rights to convert, rights to subscribe, payment of dividends,
reorganization or other exchanges, tender offers, and voting rights), and
Pledgor agrees that Pledgee shall not have any responsibility or liability for
informing Pledgor of any such changes or potential changes or for taking any
action or omitting to take any action with respect thereto.

            7.10 Pledgor shall at all times keep its books and records
concerning the Collateral at its chief executive office.  Pledgor shall not
change the location of its chief


                                          5
<PAGE>

executive office without giving Pledgee at least thirty (30) days' prior written
notice thereof.

            7.11 Pledgor shall prevent the Company from issuing any
additional Shares or Options.

       8.   SHARE ADJUSTMENTS.  In the event that during the term of this
Agreement any reclassification, readjustment, or other change is declared or
made in the capital structure of any Company, Pledgor shall give Pledgee prompt
written notice thereof and all new substituted and additional shares or other
Securities, issued or issuable to Pledgor by reason of any such change or
exercise shall be subject to the security interest created hereby and Pledgor
shall as soon as practicable but in no event more than 10 days thereafter, take
all of the actions required under Section 3 with respect thereto.

       9.   OPTIONS.  In the event that during the term of this Agreement
Options shall be issued or exercised in connection with the Collateral, Pledgor
shall give Pledgee prompt written notice thereof and such Options acquired by
Pledgor shall be immediately assigned by Pledgor to Pledgee pursuant to an
assignment agreement in form and substance satisfactory to Pledgee in its sole
and absolute discretion, and all new shares or other Securities so acquired by
Pledgor shall also be subject to the security interest created hereby and
Pledgor shall as soon as practicable but in no event more than 10 days
thereafter, take all of the actions required under Section 3 with respect
thereto.

       10.  CONSENT.  Pledgor hereby consents that, from time to time, before
or after the occurrence or existence of any Event of Default with or without
notice to or assent from Pledgor, any other security at any time held by or
available to Pledgee for any of the Secured Obligations or any other security at
any time held by or available to Pledgee of any other person, firm, or
corporation secondarily or otherwise liable for any of the Secured Obligations,
may be exchanged, surrendered, or released and any of the Secured Obligations
may be changed, altered, renewed, extended, continued, surrendered, compromised,
waived, or released, in whole or in part, as Pledgee may see fit.  Pledgor shall
remain bound under this Agreement notwithstanding any such exchange, surrender,
release, alteration, renewal, extension, continuance, compromise, waiver, or
inaction, or extension of further credit.

       11.  EVENTS OF DEFAULT.  The occurrence of an Event of Default under
the Loan Agreement shall constitute an event of default ("EVENT OF DEFAULT")
under this Agreement.

       12.  REMEDIES UPON DEFAULT.

            12.1 Upon the occurrence of an Event of Default, Pledgee shall
have, in addition to any other rights given by law or in this Agreement, in the
Loan Agreement, or in any other agreement between Pledgee and Pledgor, all of
the rights and remedies with respect to the Collateral of a secured party under
the Code, and also shall have, without limitation, the following rights, which
Pledgor hereby agrees to be


                                          6
<PAGE>

commercially reasonable:

                 (a)  to receive all amounts payable in respect of the
Collateral to Pledgor under Section 6.1(b) hereof;

                 (b)  to register all or any part of the Collateral on the
books of the Company in Pledgee's name or the name of its nominee or nominees;

                 (c)  to vote all or any part of the Shares (whether or not
transferred into the name of the Pledgee) in accordance with Section 6.2 hereof,
and give all consents, waivers and ratifications in respect of the Collateral
and otherwise act with respect thereto as though it were the outright owner
thereof; PLEDGOR HEREBY IRREVOCABLY CONSTITUTES AND APPOINTS PLEDGEE THE PROXY
AND ATTORNEY-IN-FACT OF PLEDGOR, COUPLED WITH AN INTEREST, WITH FULL POWER OF
SUBSTITUTION FOR ANY AND ALL OF SUCH PURPOSES;  WHICH PROXY AND POWER OF
ATTORNEY SHALL CONTINUE IN FULL FORCE AND EFFECT AND TERMINATE UPON THE EARLIER
TO OCCUR OF (a) UPON THE INDEFEASIBLE PAYMENT IN FULL OF THE SECURED
OBLIGATIONS, AND (b) TEN (10) YEARS FROM THE DATE HEREOF.

                 (d)  at any time or from time to time, to sell, assign and
deliver, or grant options to purchase, all or any part of the Collateral, or any
interest therein, at any public or private sale, without demand of performance,
advertisement or notice of intention to sell or of the time or place of sale or
adjournment thereof or to redeem or otherwise (all of which are hereby waived by
Pledgor), for cash, on credit or for other property, for immediate or future
delivery without any assumption of credit risk, and for such price or prices and
on such terms as the Pledgee in its absolute discretion may determine; PROVIDED,
that at least five (5) days notice of the time and place of any such sale shall
be given to Pledgor.  Pledgee shall not be obligated to make any such sale of
Collateral regardless of whether any such notice of sale has therefore been
given.  Pledgor hereby waives any other requirement of notice, demand, or
advertisement for sale, to the extent permitted by law.  Pledgor hereby waives
and releases to the fullest extent permitted by law any right or equity of
redemption with respect to the Collateral, whether before or after sale
hereunder, and all rights, if any, of marshalling the Collateral and any other
security for the Secured Obligations or otherwise.  At any such sale, unless
prohibited by applicable law, Pledgee may bid for and purchase all or any part
of the Collateral so sold free from any such right or equity of redemption.
Pledgee shall not be liable for failure to collect or realize upon any or all of
the Collateral or for any delay in so doing nor shall Pledgee be under any
obligation to take any action whatsoever with regard thereto;

                 (e)  to buy the Collateral, in its own name, or in the name
of a designee or nominee.  Pledgee shall have the right to execute any document
or form, in its name or in the name of the Pledgor, that may be necessary or
desirable in connection with such sale of the Collateral.


                                          7
<PAGE>

                 (f)  to sell all or any part of the Collateral by a private
placement, restricting bidders and prospective purchasers to those who will
represent and agree that they are purchasing for investment only and not for
distribution.  In so doing, Pledgee may solicit offers to buy the Collateral, or
any part of it for cash, from a limited number of investors deemed by Pledgee,
in its reasonable judgment, to be responsible parties who might be interested in
purchasing the Collateral.  If Pledgee shall solicit such offers from not less
than four (4) such investors, then the acceptance by Pledgee of the highest
offer obtained therefore shall be deemed to be a commercial reasonable method of
disposition of such Collateral, even though the sales price established and/or
obtained may be substantially less than the price that would be obtained
pursuant to a public offering.  Notwithstanding the foregoing, should Pledgee
determine that, prior to any public offering of any securities contained in the
Collateral, such securities should be registered under the '33 Act and/or
registered or qualified under any other federal or state law, and that such
registration and/or qualification is not practical, Pledgor agrees that it will
be commercially reasonable if a private sale is arranged so as to avoid a public
offering even if offers are solicited from fewer than four (4) investors, and
even though the sales price established and/or obtained may be substantially
less than the price that would be obtained pursuant to a public offering.

       13.  PLEDGEE AS PLEDGOR'S ATTORNEY-IN FACT.  Pledgor hereby
irrevocably appoints Pledgee as its attorney-in-fact, coupled with an interest,
(i) to arrange for the register, at any time after the occurrence of an Event of
Default, of the Collateral on the books of the Company to the name of Pledgee or
to the name of Pledgee's nominee and (ii) to receive, endorse and collect all
instruments made payable to Pledgor of any dividend, distribution or other
payment on account of the Collateral, or any part thereof, and to give full
discharge for the same and to execute and file governmental notifications and
reporting forms.  Pledgor hereby further authorizes Pledgee to perform any and
all acts which Pledgee deems necessary for the protection and preservation of
the Collateral or of the value of Pledgee's security interest therein, including
but not limited to receiving income thereon as additional security hereunder,
and all expenses paid or incurred by Pledgee in connection therewith shall
constitute Bank Expenses.  Pledgor hereby further grants to Pledgee a power of
attorney coupled with an interest to execute all agreements, forms,
applications, documents and instruments and to take all actions and do all
things as could be executed, taken, or done by Pledgor in connection with the
protection and preservation of the Collateral or this Agreement.  This power of
attorney is irrevocable and authorizes Pledgee to act for Pledgor in connection
with the matters described herein without notice to or demand upon Pledgor.

       14.  GENERAL PROVISIONS.

            14.1 CUMULATIVE REMEDIES; NO PRIOR RECOURSE TO COLLATERAL.  The
enumeration herein of Pledgee's rights and remedies is not intended to be
exclusive, and such rights and remedies are in addition to and not by way of
limitation of any other rights or remedies that the Pledgee may have under the
Loan Agreement, the Loan Documents, the Code, or other applicable law.  Pledgee
shall have the right, in its sole discretion, to


                                          8
<PAGE>

determine which rights and remedies are to be exercised and in which order.  The
exercise of one right or remedy shall not preclude the exercise of any others,
all of which shall be cumulative.

            14.2 NO IMPLIED WAIVERS.  No act, failure, or delay by Pledgee
shall constitute a waiver of any of its rights and remedies.  No single or
partial waiver by Pledgee of any provision of this Agreement or any other Loan
Document, or of a breach or default hereunder or thereunder, or of any right or
remedy which the Pledgee may have, shall operate as a waiver of any other
provision, breach, default, right, or remedy or of the same provision, breach,
default, right, or remedy on a future occasion.  No waiver by Pledgee shall
affect its rights to require strict performance of this Agreement.

            14.3 NOTICES.  All notices or demands by any party hereto to the
other party and relating to this Agreement shall be sent in accordance with the
terms of Section 9.1 of the Loan Agreement.

            14.4 SUCCESSORS AND ASSIGNS.  This Agreement shall bind the
successors and assigns of Pledgor, and shall inure to the benefit of the
successors and assigns of Pledgee; PROVIDED, HOWEVER, that Pledgor may not
assign this Agreement nor delegate any of its duties hereunder without Pledgee's
prior written consent and any prohibited assignment shall be absolutely void.
Pledgee may assign this Agreement and its rights and duties hereunder and no
consent or approval by Pledgor is required in connection with any such
assignment.  Pledgee reserves the right to sell, assign, transfer, negotiate, or
grant participations in all or any part of, or any interest in Pledgee's rights
and benefits hereunder.  In connection with any such assignment or
participation, Pledgee may disclose all documents and information which Pledgee
now or hereafter may have relating to Pledgor or Pledgor's business to any
prospective or actual Transferee, subject to the terms of Section 9.5(e) of the
Loan Agreement.

            14.5 EXHIBITS AND SCHEDULES.  All of the exhibits and schedules
attached hereto shall be deemed incorporated by reference.

            14.6 NO PRESUMPTION AGAINST ANY PARTY.  Neither this Agreement
nor any uncertainty or ambiguity herein shall be construed or resolved against
Pledgor or Pledgee, whether under any rule of construction or otherwise.  On the
contrary, this Agreement has been reviewed by each of the parties and their
counsel and shall be construed and interpreted according to the ordinary meaning
of the words used so as to accomplish fairly the purposes and intentions of all
parties hereto.

            14.7 SECTION HEADINGS.  Headings and numbers have been set forth
herein for convenience only.  Unless the contrary is compelled by the context,
everything contained in each section applies equally to this entire Agreement.

            14.8 SEVERABILITY OF PROVISIONS.  If any provision of this
Agreement is for any reason held to be invalid, illegal or unenforceable in any
respect, that provision


                                          9
<PAGE>

shall not affect the validity, legality or enforceability of any other provision
of this Agreement.

            14.9 ENTIRE AGREEMENT; AMENDMENTS AND WAIVERS.  This Agreement
constitutes the entire agreement between Pledgor and Pledgee pertaining to the
subject matter contained herein.  Any provision of this Agreement may be amended
or waived if, but only if, such amendment or waiver is in writing and is signed
by the party asserted to be bound thereby, and then such amendment or waiver
shall be effective only in the specific instance and specific purpose for which
given.

            14.10     COUNTERPARTS; TELEFACSIMILE EXECUTION.  This Agreement
may be executed in any number of counterparts and by different parties on
separate counterparts, each of which, when executed and delivered, shall be
deemed to be an original, and all of which, when taken together, shall
constitute but one and the same Agreement.  Delivery of an executed counterpart
of this Agreement by telefacsimile shall be equally as effective as delivery of
a manually executed counterpart of this Agreement.  Any party delivering an
executed counterpart of this Agreement by telefacsimile also shall deliver a
manually executed counterpart of this Agreement but the failure to deliver a
manually executed counterpart shall not affect the validity, enforceability, and
binding effect of this Agreement.

            14.11     TERMINATION BY PLEDGEE.  After termination of the Loan
Agreement and when Pledgee has received payment and performance, in full, of the
Secured Obligations, Pledgee shall execute and deliver to Pledgor a termination
of all of the security interests granted by Pledgor hereunder and, to the extent
they have been delivered to Pledgee and not disposed of in accordance with this
Agreement, certificates evidencing the Shares.

       15.  GOVERNING LAW; JUDICIAL REFERENCE.

            15.1 GOVERNING LAW.  This Agreement shall be deemed to have been
made in the State of California and the validity, construction, interpretation,
and enforcement hereof, and the rights of the parties hereto, shall be
determined under, governed by, and construed in accordance with the internal
laws of the State of California, without regard to principles of conflicts of
law.

            15.2 JUDICIAL REFERENCE.

                 (a)  Other than (i) nonjudicial foreclosure and all matters
in connection therewith regarding security interests in real or personal
property; or (ii) the appointment of a receiver, or the exercise of other
provisional remedies (any and all of which may be initiated pursuant to
applicable law), each controversy, dispute or claim between the parties arising
out of or relating to this Agreement, which controversy, dispute or claim is not
settled in writing within thirty (30) days after the "CLAIM DATE" (defined as
the date on which a party subject to this Agreement gives written notice to all
other parties that a controversy, dispute or claim exists), will be settled by a
reference proceeding in


                                          10
<PAGE>

California in accordance with the provisions of Section 638 ET SEQ. of the
California Code of Civil Procedure, or their successor section ("CCP"), which
shall constitute the exclusive remedy for the settlement of any controversy,
dispute or claim concerning this Agreement, including whether such controversy,
dispute or claim is subject to the reference proceeding and except as set forth
above, the parties waive their rights to initiate any legal proceedings against
each other in any court or jurisdiction other than the Superior Court in the
County where the Real Property, if any, is located or Los Angeles County if none
(the "COURT").  The referee shall be a retired Judge of the Court selected by
mutual agreement of the parties, and if they cannot so agree within forty-five
(45) days after the Claim Date, the referee shall be promptly selected by the
Presiding Judge of the Court (or his representative).  The referee shall be
appointed to sit as a temporary judge, with all of the powers for a temporary
judge, as authorized by law, and upon selection should take and subscribe to the
oath of office as provided for in Rule 244 of the California Rules of Court (or
any subsequently enacted Rule).  Each party shall have one peremptory challenge
pursuant to CCP Section 170.6.  The referee shall (a) be requested to set the
matter for hearing within sixty (60) days after the date of selection of the
referee and (b) try any and all issues of law or fact and report a statement of
decision upon them, if possible, within ninety (90) days of the Claim Date.  Any
decision rendered by the referee will be final, binding and conclusive and
judgment shall be entered pursuant to CCP Section 644 in any court in the State
of California having jurisdiction.  Any party may apply for a reference
proceeding at any time after thirty (30) days following notice to any other
party of the nature of the controversy, dispute or claim, by filing a petition
for a hearing and/or trial.  All discovery permitted by this Agreement shall be
completed no later than fifteen (15) days before the first hearing date
established by the referee.  The referee may extend such period in the event of
a party's refusal to provide requested discovery for any reason whatsoever,
including, without limitation, legal objections raised to such discovery or
unavailability of a witness due to absence or illness.  No party shall be
entitled to "priority" in conducting discovery.  Depositions may be taken by
either party upon seven (7) days written notice, and request for production or
inspection of documents shall be responded to within ten (10) days after
service.  All disputes relating to discovery which cannot be resolved by the
parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Superior Court is empowered to issue temporary and/or provisional
remedies, as appropriate.

                 (b)  Except as expressly set forth in this Agreement, the
referee shall determine the manner in which the reference proceeding is
conducted including the time and place of all hearings, the order of
presentation of evidence, and all other questions that arise with respect to the
course of the reference proceeding.  All proceedings and hearings conducted
before the referee, except for trial, shall be conducted without a court
reporter except that when any party so requests, a court reporter will be used
at any hearing conducted before the referee.  The party making such a request
shall have the obligation to arrange for and pay for the court reporter.  The
costs of the court reporter at the trial shall be borne equally by the parties.

                 (c)  The referee shall be required to determine all issues
in


                                          11
<PAGE>

accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties.  The referee shall issue a single judgment at the
close of the reference proceeding which shall dispose of all of the claims of
the parties that are the subject of the reference.  The parties hereto expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee.  The parties hereto
expressly reserve the right to findings of fact, conclusions of laws, a written
statement of decision, and the right to move for a new trial or a different
judgment, which new trial, if granted, is also to be a reference proceeding
under this provision.

                 (d)  In the event that the enabling legislation which
provides for appointment of a referee is repealed (and no successor statute is
enacted), any dispute between the parties that would otherwise be determined by
the reference procedure herein described will be resolved and determined by
arbitration.  The arbitration will be conducted by a retired judge of the Court,
in accordance with the California Arbitration Act, Section 1280 through Section
1294.2 of the CCP as amended from time to time.  The limitations with respect to
discovery as set forth hereinabove shall apply to any such arbitration
proceeding.

       IN WITNESS WHEREOF, the parties have executed this Agreement on the
date first written above.

                                  PROMISSORY NOTE
                           [PROSPECT MEDICAL GROUP, INC.]


$5,000,000                                               Los Angeles, California
                                                              September 25, 1997


          1.   FOR VALUE RECEIVED, Prospect Medical Group, Inc., a California
professional corporation ("MAKER"), promises to pay to the order of Prospect
Medical Systems, Inc., a Delaware corporation ("PAYEE"), on or before the
Maturity Date unless sooner accelerated in accordance with the terms hereof, the
principal sum of Five Million Dollars ($5,000,000), or such lesser sum as shall
equal the aggregate outstanding principal amount of the loans made by Payee to
Maker hereunder.  As used herein the term "MATURITY DATE" has the meaning given
to such term in that certain Revolving Credit Agreement, dated as of July 3,
1997, between Prospect Medical Holdings, Inc., a Delaware corporation, and
Imperial Bank (as amended or restated from time to time, the "CREDIT
AGREEMENT").

          2.   This Promissory Note shall bear interest at a per annum rate
equal to six percent (6%).  All computations of interest shall be calculated on
the basis of a year of three hundred sixty-five (365) days for the actual days
elapsed.  Interest shall accrue from the date of this Promissory Note to the
date of repayment of this Promissory Note in accordance with the provisions
hereof.  Maker shall pay all accrued but unpaid interest on the principal
balance hereof, in arrears, on the first day of each and every month.

          3.   Maker hereby authorizes Payee to record in its books and records
the date and amount of the loans made by Payee to Maker hereunder, and of each
payment of principal made by Maker, and Maker agrees that all such notations
shall, in the absence of manifest error, be conclusive as to the matters so
noted; PROVIDED, HOWEVER, any failure by Payee to make such notation with
respect to any loan or payment thereof shall not limit or otherwise affect
Maker's obligations under this Promissory Note.

          4.   Maker shall make all payments hereunder in lawful money of the
United States of America and in immediately available funds to the holder hereof
("HOLDER") at Holder's office or to such other address as Holder may from time
to time specify by notice to Maker.

          5.   In no event shall the interest rate and other charges hereunder
exceed the highest rate permissible under any law which a court of competent
jurisdiction shall, in a final determination, deem applicable hereto.  In the
event that such a court determines that Holder has received interest and other
charges hereunder in excess of the highest rate applicable hereto, such excess
shall be deemed received on account of, and shall automatically be applied to
reduce, the principal balance hereof, and the provisions hereof shall be 


                                          1
<PAGE>

deemed amended to provide for the highest permissible rate.  If there is no
principal balance outstanding, Holder shall refund to Maker such excess.

          6.   The unpaid principal balance hereof together with all accrued but
unpaid interest thereon shall be all due and payable upon (i) failure by Maker
to pay any installment of principal or interest due hereunder when due,
(ii) commencement of any proceeding by or against Maker under any bankruptcy or
insolvency laws, or (iii) the occurrence of an "Event of Default" under the
Credit Agreement.

          7.   Maker hereby waives presentment for payment, notice of dishonor,
protest and notice of protest.

          8.   This Promissory Note shall be governed by and construed in
accordance with the internal laws of the State of California without regard to
principles of conflicts of laws.

          IN WITNESS WHEREOF, Maker has duly executed this Promissory Note as of
the date first above written.

               2.2  RIGHTS AND REMEDIES.  All of the rights, benefits, remedies,
privileges and claims of Assignor with respect to the Transaction Documents
(collectively, the "RIGHTS AND REMEDIES"), including, without limitation, (i)
all rights to monies or payments owing to Assignor under the Transaction
Documents, and any and all security therefor and for all other obligations owing

respect to any breach of the representations, warranties and covenants set forth
in any of the Transaction Documents, and (iv) the proceeds thereof (the
Transaction Documents and the Rights and Remedies are collectively referred to
herein as, the "COLLATERAL").

          3.   RIGHT AND REMEDIES GENERALLY.  Prior to the occurrence of a
breach or default of any of the agreements, covenants and obligations of
Assignor under the Guaranty (a "DEFAULT"), Assignor will enforce all of its
Rights and Remedies diligently and in good faith.  Effective from and after the
occurrence of a Default, Assignor hereby irrevocably authorizes and empowers
Bank, in Bank's own discretion, to assert as Bank may deem proper, either
directly or on behalf of Assignor, any of the Rights and Remedies which Assignor
may from time to time have under the Transaction Documents, and to receive and
collect all damages, awards and other monies resulting therefrom and to apply
the same on account of any of the Guaranteed Obligations.

          4.   FURTHER ASSURANCES.  Assignor shall execute and deliver to Bank
concurrently with Assignor's execution of this Assignment, and from time to time
at the request of Bank, all financing statements, continuation financing

with the terms of the Security Agreement until the Security Agreement is
terminated in accordance with its terms.

          6.   ATTORNEY-IN-FACT.  Assignor hereby irrevocably makes,
constitutes, and appoints Bank (and Bank's officers, employees, or agents) as
Assignor's true and lawful agent and attorney-in-fact for the purposes of
enabling Bank or its agent(s) after the occurrence of a Default to (a) assert
such Rights and Remedies and to collect such damages, awards and other monies
and to apply them in the manner set forth hereinabove, and (b) to sign the name
of Assignor on any documents which need to be executed, recorded, or filed,



                                          3

and to do any and all things necessary in the name and on behalf of Assignor in
order to protect Bank's interests in the Transaction Documents.  Assignor agrees
that neither Bank, nor any of its designers or attorneys-in-fact, will be liable
for any act of commission or omission, or for any error of judgment or mistake
of fact or law with respect to the exercise of the power of attorney granted
under this Section 6, other than as a result of its or their gross negligence or
wilful misconduct.  The power of attorney granted under this Section 6 is
coupled with an interest and shall be irrevocable until all of the Guaranteed
Obligations have been paid in full, the Guaranty terminated, and Assignor's
duties under this Assignment have been discharged in full.

          7.   MODIFICATION OF RIGHTS AND REMEDIES.  Assignor shall keep Bank
informed of all circumstances bearing upon the Rights and Remedies and shall
immediately provide Bank with copies of any notices delivered to Assignor in
connection with the Transaction Documents.  Assignor shall also provide Bank
with a copy of any notice sent by Assignor in connection with the Transaction
Documents, concurrently with the sending of any such notice.  Assignor shall not
waive, amend, alter or modify any of the Rights and Remedies in any material
respect without the prior written consent of Bank.  Assignor shall not, without
Bank's prior written consent, amend, alter, modify or terminate any of the
Transaction Documents, or waive any of the provisions thereof, or do or permit
any act in contravention thereof.

          8.   ASSIGNOR TO REMAIN LIABLE.  Notwithstanding the foregoing,
Assignor expressly acknowledges and agrees that it shall remain liable under the
Transaction Documents to observe and perform all of the conditions and
obligations in the Transaction Documents which Assignor is bound to observe and
perform, and that neither this Assignment, nor any action taken pursuant hereto,
shall cause Bank to be under any obligation or liability in any respect
whatsoever to observe or perform any of the representations, warranties,
conditions, covenants, agreements or terms of the Transaction Documents.

          9.   COUNTERPARTS; EFFECTIVENESS.  This Assignment may be executed in
any number of counterparts, each of which, when executed and delivered, shall be
deemed to be an original.  All of such counterparts, taken together, shall
constitute but one and the same agreement.  This Assignment shall become
effective upon the execution of a counterpart of this Assignment by each of the
parties hereto.

          10.  NOTICES.  All notices, requests and other communications to any
party hereunder shall be sent in accordance with Section 15 of the Guaranty.

          11.  MODIFICATIONS AND AMENDMENTS.  This Assignment shall not be

          12.  SEVERABILITY.  If any provision of this Assignment is held to be
illegal, invalid or unenforceable under present or future laws, the legality,
validity and enforceability of the remaining provisions of this Assignment shall
not be affected thereby, and this Assignment shall be liberally construed so as
to carry out the intent of the parties to it.

          13.  GOVERNING LAW; SUCCESSORS AND ASSIGNS; ENTIRE AGREEMENT.  This
Assignment (a) shall be governed and construed according to the laws of the
State of California, without regard to principles of conflicts of law; (b) shall
be binding upon and inure to the benefit of the parties hereto and their
respective successors and assigns; and (c) embodies the entire agreement and
understanding between the parties with respect to the subject matter hereof and
supersedes all prior agreements, consents and understandings relating to such
subject matter.

          14.  JUDICIAL REFERENCE.

               14.1 REFERENCE PROCEEDING.  Other than (i) nonjudicial
foreclosure and all matters in connection therewith regarding security interests
in real or personal property; or (ii) the appointment of a receiver, or the
exercise of other provisional remedies (any and all of which may be initiated
pursuant to applicable law), each controversy, dispute or claim between the
parties arising out of or relating to this Assignment, which controversy,
dispute or claim is not settled in writing within thirty (30) days after the
"CLAIM DATE" (defined as the date on which either Assignor or Bank gives written
notice to the other that a controversy, dispute or claim exists), will be
settled by a reference proceeding in California in accordance with the
provisions of Section 638 ET SEQ. of the California Code of Civil Procedure, or
their successor section ("CCP"), which shall constitute the exclusive remedy for
the settlement of any controversy, dispute or claim concerning this Assignment,
including whether such controversy, dispute or claim is subject to the reference
proceeding and except as set forth above, the parties waive their rights to
initiate any legal proceedings against each other in any court or jurisdiction
other than the Superior Court in Los Angeles County (the "COURT").  The referee
shall be a retired Judge of the Court selected by mutual agreement of the
parties, and if they cannot so agree within forty-five (45) days after the Claim
Date, the referee shall be promptly selected by the Presiding Judge of the Court
(or his representative).  The referee shall be appointed to sit as a temporary
judge, with all of the powers for a temporary judge, as authorized by law, and
upon selection should take and subscribe to the oath of office as provided for
in Rule 244 of the California Rules of Court (or any subsequently enacted Rule).
Each party shall have one peremptory challenge pursuant to CCP Section 170.6.
The referee shall (a) be requested to set the matter for hearing within sixty
(60) days after the date of selection of the referee and (b) try any and all
issues of law or fact and report a statement of decision upon them, if possible,
within ninety (90) days of the Claim Date.  Any decision rendered by the referee
will be final, binding and conclusive and judgment shall be entered pursuant to
CCP Section 644 in any court in the State of California having jurisdiction.
Any party may apply for a reference proceeding at any time after thirty (30)
days following notice to any other party of the nature of the controversy,
dispute or claim, by filing a petition for a hearing and/or


                                          5
<PAGE>

trial.  All discovery permitted by this Assignment shall be completed no later
than fifteen (15) days before the first hearing date established by the referee.
The referee may extend such period in the event of a party's refusal to provide
requested discovery for any reason whatsoever, including, without limitation,
legal objections raised to such discovery or unavailability of a witness due to
absence or illness.  No party shall be entitled to "priority" in conducting
discovery.  Depositions may be taken by either party upon seven (7) days written
notice, and request for production or inspection of documents shall be responded
to within ten (10) days after service.  All disputes relating to discovery which
cannot be resolved by the parties shall be submitted to the referee whose
decision shall be final and binding upon the parties.  Pending appointment of
the referee as provided herein, the Court is empowered to issue temporary and/or
provisional remedies, as appropriate.

               14.2 MANNER OF REFERENCE PROCEEDING.  Except as expressly set
forth in this Assignment, the referee shall determine the manner in which the
reference proceeding is conducted including the time and place of all hearings,
the order of presentation of evidence, and all other questions that arise with
respect to the course of the reference proceeding.  All proceedings and hearings
conducted before the referee, except for trial, shall be conducted without a
court reporter except that when any party so requests, a court reporter will be
used at any hearing conducted before the referee.  The party making such a
request shall have the obligation to arrange for and pay for the court reporter.
The costs of the court reporter at the trial shall be borne equally by the
parties.

               14.3 DUTIES OF REFEREE.  The referee shall be required to
determine all issues in accordance with existing case law and the statutory laws
of the State of California.  The rules of evidence applicable to proceedings at
law in the State of California will be applicable to the reference proceeding.
The referee shall be empowered to enter equitable as well as legal relief, to
provide all temporary and/or provisional remedies and to enter equitable orders
that will be binding upon the parties.  The referee shall issue a single
judgment at the close of the reference proceeding which shall dispose of all of
the claims of the parties that are the subject of the reference.  The parties
hereto expressly reserve the right to contest or appeal from the final judgment
or any appealable order or appealable judgment entered by the referee.  The
parties hereto expressly reserve the right to findings of fact, conclusions of
laws, a written statement of decision, and the right to move for a new trial or
a different judgment, which new trial, if granted, is also to be a reference
proceeding under this provision.

               14.4 ARBITRATION ALTERNATIVE.  In the event that the enabling
legislation which provides for appointment of a referee is repealed (and no
successor statute is enacted), any dispute between the parties that would
otherwise be determined by the reference procedure herein described will be
resolved and determined by arbitration.  The arbitration will be conducted by a
retired judge of the Court, in accordance with the California Arbitration Act,
Section 1280 through Section 1294.2 of the CCP as amended from time to


                                          6
<PAGE>

time.  The limitations with respect to discovery as set forth hereinabove shall
apply to any such arbitration proceeding.

     EXECUTED as of the date first above written.

interests in the Collateral, and proceed to collect the same and apply the net
cash proceeds therefrom to the Secured Obligations;

Manager shall also give notice of the time and place of said sale by publishing
a notice at least five (5) calendar days before the date of the sale in a
newspaper of general circulation, if one exists, in the county in which the sale
is to be held;

                    (e)    Manager may, in its own name, or in the name of a
designee or nominee, credit bid and purchase at any public sale;

                    (f)    Physician Group shall pay all Expenses; and

                    (g)    Any portion of the Secured Obligations which remains
unpaid after disposition of the Collateral as provided above shall be paid
immediately by Physician Group.  Any excess which exists after disposition of
the Collateral and payment in full of the Secured Obligations shall be returned
promptly, without interest and subject to the rights of third persons, to
Physician Group by Manager.

               8.2  FURTHER DOCUMENTATION.  Upon the exercise by Manager of any
power, right, privilege, or remedy pursuant to this Security Agreement which
requires any consent, approval, registration, qualification, or authorization of
any Governmental Authority, Physician Group agrees to execute and deliver, or
will cause the execution and delivery of, all applications, certificates,
instruments, assignments, and other documents and papers that Manager or any
purchaser of the Collateral may be required to obtain for such governmental
consent, approval, registration, qualification, or authorization.

               8.3  CUMULATIVE REMEDIES; WAIVERS.  The rights and remedies of
Manager under this Security Agreement, the Management Agreement, and all other
agreements contemplated hereby and thereby shall be cumulative.  Manager shall
have all other rights and remedies not inconsistent herewith as provided under
the Code, by law, or in equity.  No exercise by Manager of any one right or
remedy shall be deemed an election of remedies, and no waiver by Manager of any
default on Physician Group's part shall be deemed a continuing waiver of any
further defaults.  No delay by Manager shall constitute a waiver, election or
acquiescence with respect to any right or remedy.

                   SUBORDINATION AND NOTE CANCELLATION AGREEMENT


     This SUBORDINATION AND NOTE CANCELLATION AGREEMENT (this "AGREEMENT"),
dated as of September 25, 1997, is entered into by and among SINNADURAI E.
MOORTHY, M.D. ("DR. MOORTHY"), KARUNYAN ARULANANTHAM, M.D. ("DR. ARULANANTHAM")
(Dr. Moorthy and Dr. Arulanantham are sometimes collectively referred to herein
as "SUBORDINATE CREDITORS" and individually as a "SUBORDINATE CREDITOR"),
PROSPECT MEDICAL HOLDINGS, INC., a Delaware corporation ("BORROWER"), PROSPECT
MEDICAL SYSTEMS, INC., a Delaware corporation ("MANAGER"), PROSPECT MEDICAL
GROUP, INC., a California professional corporation ("PURCHASER"), and IMPERIAL
BANK, a California banking corporation ("SENIOR CREDITOR"), with reference to
the following facts:

                                  R E C I T A L S

     A.   Subordinate Creditors, The Arulanantham Charitable Remainder Trust
("TRUST"), Purchaser, and Sierra Primary Care Medical Group, Inc., a California
professional corporation ("COMPANY"), are party to that certain Agreement for
the Purchase and Sale of Stock of Sierra Primary Care Medical Group, Inc., dated
as of September 23, 1997 (the "STOCK PURCHASE AGREEMENT"), pursuant to which
Purchaser is purchasing one hundred percent (100%) of the stock of Company from
Subordinate Creditors and Trust.

     B.   Pursuant to the terms of the Stock Purchase Agreement, Purchaser is
concurrently herewith executing and delivering to each Subordinate Creditor a
Contingent Promissory Note, dated as of September 25, 1997 (each as it may have
been renewed, extended or rearranged, a "SUBORDINATE NOTE" and collectively, the
"SUBORDINATE NOTES"), each in the original principal sum of One Million One
Hundred Twenty-Five Thousand Dollars ($1,125,000).  In addition, pursuant to the
terms of the Stock Purchase Agreement, Borrower is concurrently herewith
executing and delivering to each Subordinate Creditor a Subordinated Guaranty,
dated as of September 25, 1997 (each, a "SUBORDINATE GUARANTY" and collectively,
the "SUBORDINATE GUARANTEES"), in order to guaranty the payment of the
Subordinate Notes.  All liens, security interests and assignments now or
hereafter securing payment or performance of the Subordinate Notes and/or the
Subordinate Guarantees are herein called "SUBORDINATE LIENS."

     C.   Borrower has previously executed and delivered to Senior Creditor that
certain Secured Revolving Note, dated July 3, 1997 (as it may have been renewed,
extended and rearranged, the "NOTE"), in the original principal sum of Ten
Million Dollars ($10,000,000).  The Note has been issued pursuant to that
certain Revolving Credit Agreement of even date with the Note (as it may have
been amended, supplemented or restated, the "LOAN AGREEMENT") between Borrower
and Senior Creditor.  All liens, security interests and assignments now or
hereafter securing payment or performance of the Note and/or the Loan Agreement
are herein called "SENIOR LIENS."  The Senior Liens include,


                                          1
<PAGE>

without limitation, the security instruments described on EXHIBIT A, attached
hereto and incorporated herein.

     D.   Manager has previously executed and delivered to Senior Creditor that
certain Continuing Guaranty, dated as of even date with the Loan Agreement and
the Note ("MANAGER GUARANTY"), pursuant to which Manager has guaranteed the
payment and performance of Borrower's obligations owing to Senior Creditor under
the Note and the Loan Agreement.

     E.   Manager and Purchaser have previously executed and delivered that
certain Management Services Agreement, dated as of June 4, 1996, as amended (the
"MANAGEMENT AGREEMENT"), pursuant to which Manager provides management services
to Purchaser in consideration of certain management fees, all as more
particularly set forth in the Management Agreement.  In order to secure
Purchaser's obligations owing to Manager, Manager and Purchaser have previously
executed and delivered that certain Security Agreement, dated as of July 3,
1997, as amended by that certain Amendment Number One, dated July 14, 1997 (the
"SECURITY AGREEMENT"), pursuant to which Purchaser has granted to Manager a
first priority security interest and lien upon certain assets of Company.  Both
the Management Agreement and the Security Agreement have been collaterally
assigned by Manager to Senior Creditor, pursuant to a Collateral Assignment of
Transaction Documents, dated as of July 3, 1997, between Manager and Senior
Creditor, in order to secure Manager's obligations owing to Senior Creditor
under the Manager Guaranty.

     F.   Borrower, Manager and Purchaser are part of a group of companies under
common control which all benefit from the loans made by Senior Creditor under
the Loan Agreement and evidenced by the Note.  Borrower has requested that
Senior Creditor make a loan under the Loan Agreement to Borrower, which Borrower
shall relend to Manager and Manager shall relend to Purchaser such that
Purchaser will be able to have funds necessary to pay the cash consideration to
Subordinate Creditors and Trust pursuant to the terms of the Stock Purchase
Agreement to acquire the stock of Company.  As a condition to its making such
loan to Borrower, Senior Creditor has required that Borrower's obligations under
the Subordinate Guarantees and Purchaser's obligations under the Subordinate
Notes and the Stock Purchase Agreement, and the Subordinate Liens securing any
of the same, be subordinated to Borrower's indebtedness under the Loan Agreement
and the Note, the Senior Liens securing same, and Purchaser's obligations under
the Management Agreement and the Security Agreement.

     G.   The parties hereto now hereby agree to subordinate the lien position,
payment and performance of the Subordinate Notes, the Stock Purchase Agreement,
the Subordinate Guarantees and the Subordinate Liens to the payment and
performance of the Management Agreement, the Security Agreement, the Note, the
Loan Agreement and the Senior Liens, all as set forth in the succeeding
provisions of this Agreement (which shall control over any conflicting or
inconsistent recitals above).

     In consideration of the premises and the mutual agreements herein set
forth, Borrower, Manager, Purchaser, Subordinate Creditors and Senior Creditor
hereby agree as follows:

     1.   All initially capitalized terms used but not defined in this Agreement
shall have the meanings given to such terms in the Loan Agreement.  In addition,
as used in this Agreement, the following terms shall have the respective
meanings indicated:

          "SENIOR DEBT" shall mean all Debt now existing or hereafter created of
Borrower or Purchaser to Senior Creditor, whether direct or indirect, primary or
secondary, joint or several, fixed or contingent and whether originally payable
to Senior Creditor or to Manager or any other third Person and subsequently
acquired by or assigned to Senior Creditor, and whether evidenced by note,
application for or agreement for reimbursement of advance under letter of
credit, open account, overdraft, indorsement, surety agreement, guaranty or
otherwise, including, without limitation, all indebtedness evidenced by the Note
and all renewals, extensions, rearrangements, refundings and modifications of
the Note, and all Debt arising under or incurred pursuant to the Loan Agreement
and any other documents executed or delivered in connection therewith, and all
Debt arising under or incurred pursuant to the Management Agreement or the
Security Agreement.  The Senior Debt shall include amounts accruing subsequent
to the filing of any bankruptcy, receivership, insolvency or like petition.
Without limiting the generality of the foregoing, Senior Debt shall include all
obligations for fees, to indemnify, to reimburse for expenses and to reimburse
for advances (whether for the payment of taxes, insurance premiums, the
preservation or protection of property or the title thereto or for any other
reason).

          "SUBORDINATED DEBT" shall mean all Debt now existing or hereafter
created of Borrower or Purchaser to Subordinate Creditors, whether direct or
indirect, primary or secondary, joint or several, fixed or contingent and
whether originally payable to Subordinate Creditors or to a third Person and
subsequently acquired by Subordinate Creditors, and whether evidenced by note,
application for or agreement for reimbursement of advance under letter of
credit, open account, overdraft, indorsement, surety agreement, guaranty or
otherwise, including, without limitation, all Debt evidenced by the Subordinate
Notes and all renewals, extensions, rearrangements, refundings and modifications
of the Subordinate Notes, and all Debt arising under or incurred pursuant to the
Subordinate Guarantees and any other documents executed or delivered in
connection therewith.

     2.   (a) Unless and until all Senior Debt shall have been fully paid and
satisfied and the obligation of Senior Creditor to make any further loans or
advances to Borrower shall have ceased and terminated, Subordinate Creditors
will not, except as otherwise provided in SECTION 2(b) hereof, (i) ask, demand,
sue for, take or receive, or retain, from Borrower, Purchaser or any other
Person, by setoff or in any other manner, payment of all or any part of the
Subordinated Debt, (ii) forgive, cancel or discharge, or permit to be converted
into any evidence of equity or ownership, any of the Subordinated Debt, (iii)
ask,


                                          3
<PAGE>

demand or receive any security for the Subordinated Debt in addition to the
security described on EXHIBIT B attached hereto and incorporated herein
("PERMITTED SUBORDINATED LIENS"), (iv) amend the Subordinate Notes, the
Subordinate Guarantees, or any other document existing in connection with the
Subordinated Debt, or (v) declare the Subordinated Debt due and payable by
reason of any default or for any other reason, or bring or join with any
creditor in bringing any proceeding against Borrower or Purchaser under any
bankruptcy, reorganization, readjustment or arrangement of debt, suspension of
payments, receivership, liquidation or insolvency or similar law or statute now
or hereafter in effect ("PROCEEDINGS").  Subordinate Creditors hereby direct
Borrower and Purchaser to make, and Borrower and Purchaser hereby agree to make,
such prior payment of the Senior Debt to Senior Creditor.

          (b)  Notwithstanding the foregoing, Purchaser may make regularly
scheduled payments (but no prepayments) of interest and principal due on the
Subordinate Notes, PROVIDED that on the date of the proposed payment, no Event
of Default has occurred and is continuing or will result from the making of such
payment.  Upon the occurrence of an Event of Default and upon written notice
thereof given to Borrower, Purchaser and Subordinate Creditors by Senior
Creditor or its representative, no further payments shall be made by Purchaser
with respect to the principal of or interest on the Subordinate Notes, and the
Subordinate Notes shall thereupon be immediately and automatically cancelled,
and all unpaid obligations thereunder shall thereupon be immediately and
automatically extinguished, without further action required on the part of
Senior Creditor, Borrower, Purchaser, Subordinate Creditors or any other Person.
SUBORDINATE CREDITORS HEREBY ACKNOWLEDGE THAT THE TERMS OF THIS SECTION 2(b)
FORM A MATERIAL PART OF THE CONSIDERATION FOR SENIOR CREDITOR'S AGREEMENT TO
MAKE THE LOAN DESCRIBED IN RECITAL F HEREINABOVE WHICH ULTIMATELY PROVIDED THE
FUNDS TO PURCHASER FOR PAYMENT TO SUBORDINATE CREDITORS OF THE PURCHASE PRICE
UNDER THE STOCK PURCHASE AGREEMENT.

     3.   (a)  Upon any distribution of the assets of Borrower and/or Purchaser
in connection with any dissolution, winding up, liquidation or reorganization of
Borrower and/or Purchaser (whether in Proceedings or upon an assignment for the
benefit of creditors or any other marshalling of the assets and liabilities of
Borrower and/or Purchaser, or otherwise), Senior Creditor shall first be
entitled to receive payment in full of all Senior Debt before Subordinate
Creditors shall be entitled to receive any payment in respect of the
Subordinated Debt.  Upon any such dissolution, winding up, liquidation or
reorganization, any payment or distribution of assets of Borrower and/or
Purchaser of any kind or character, whether in cash, property or securities, to
which Subordinate Creditors would be entitled except for the provisions of this
Agreement (including any such payment or distribution which may be payable or
deliverable by virtue of the provisions of any securities which are subordinated
as junior in right of payment to the Subordinated Debt)


                                          4
<PAGE>

shall be made by the liquidating trustee or agent or other Persons making such
payment or distribution (whether a trustee in bankruptcy, a receiver or
liquidating trustee or otherwise) (a "PAYING PARTY"), or if received by either
Subordinate Creditor, by such Subordinate Creditor, directly to Senior Creditor,
to the extent necessary to pay in full the Senior Debt remaining unpaid, after
giving effect to any concurrent payment or distribution to Senior Creditor.
Subordinate Creditors hereby authorize and direct each Paying Party to pay over
to Senior Creditor upon demand by Senior Creditor, all such payments or
distributions without the necessity of any inquiry as to the status or balance
of the Senior Debt, and without further notice to or consent of Subordinate
Creditors.  In furtherance of the foregoing, but not by way of limitation
thereof, in the event Borrower and/or Purchaser is subject to any Proceeding,
with the result that Borrower and/or Purchaser is excused from the obligation to
pay all or part of the interest otherwise payable in respect of the Senior Debt
during the period subsequent to the commencement of any such Proceeding,
Subordinate Creditors agree that all or such part of such interest, as the case
may be, shall be payable out of, and to that extent diminish and be at the
expense of, reorganization dividends or distributions in respect of the
Subordinated Debt.

          (b)  Subordinate Creditors hereby irrevocably authorize and empower
Senior Creditor to demand, sue for, collect and receive every such payment or
distribution and give acquittance therefor, to execute, sign, endorse, transfer
and deliver any and all receipts and instruments, and to file claims and take
such other proceedings, all in the name of Subordinate Creditors, or otherwise,
as Senior Creditor may deem necessary or advisable for the enforcement of this
Agreement, but Senior Creditor has no obligation to do so.  Each Subordinate
Creditor hereby (i) agrees duly and promptly to take such action as may be
required by Senior Creditor to collect the Subordinated Debt for the account of
Senior Creditor and/or to file appropriate proofs of claim in respect of the
Subordinated Debt, (ii) authorizes and empowers Senior Creditor to vote the full
amount of the Subordinated Debt in any bankruptcy, reorganization or similar
proceeding affecting Borrower and/or Purchaser and in any meeting of creditors
of Borrower and/or Purchaser, (iii) agrees to execute and deliver to Senior
Creditor or its representatives on demand such powers of attorney, proofs of
claim and other instruments as may be requested by Senior Creditor or its
representatives in order to enable Senior Creditor to enforce any and all claims
upon or with respect to the Subordinated Debt, to collect and receive any and
all such payments or distributions which may be payable or deliverable at any
time upon or with respect to the Subordinated Debt, and to vote the full amount
of the Subordinated Debt in any proceeding or meeting referred to in clause (ii)
of this subparagraph (b).

          (c)  In the event any payment or distribution of assets of Borrower
and/or Purchaser of any kind or character, whether in cash, property or
securities, and whether or not pursuant to any dissolution, winding up,
liquidation or reorganization, not permitted by or in accordance with the
provisions of this Agreement shall be received by either Subordinate Creditor,
such payment or distribution to such Subordinate Creditor shall not be
commingled with other funds and shall be held in trust for the benefit of, and
shall be paid over or delivered to, Senior Creditor, or to its representative,
in precisely the form received (except for the endorsement or assignment of such
Subordinate Creditor where


                                          5

<PAGE>

necessary).  In the event of any failure by such Subordinate Creditor to make
any such endorsement or assignment, Senior Creditor is hereby irrevocably
authorized to make same.

          (d)  Notwithstanding the terms and provisions of this Agreement,
Subordinate Creditors shall not be entitled to be subrogated to any of the
rights of Senior Creditor against Borrower, Purchaser or any other Person or any
Senior Liens or other collateral security or rights of offset held by Senior
Creditor for the payment of the Senior Debt, nor shall Subordinate Creditors
have any right of indemnity, reimbursement or contribution against Borrower,
Purchaser or any other Person for any payment of the Senior Debt, and
Subordinate Creditors hereby expressly waive each and every such right of
subrogation, indemnity, reimbursement and contribution.

          (e)  The provisions of this Agreement are and are intended solely for
the purpose of defining the relative rights of Subordinate Creditors and Senior
Creditor, and are solely for the benefit of Senior Creditor and may not be
relied upon or enforced by any party other than Senior Creditor, and nothing
contained in this Agreement is intended to or shall impair the obligation of
Borrower and/or Purchaser, which is unconditional and absolute, to pay to
Subordinate Creditors the principal of and interest on the Subordinated Debt as
and when the same shall become due and payable in accordance with its terms
(except as otherwise provided in Section 2(b) hereof), or to affect the relative
rights of Subordinate Creditors and creditors of Borrower and Purchaser other
than Senior Creditor.

          (f)  Senior Creditor may, at any time and from time to time, without
the consent of or notice to Subordinate Creditors, and without impairing or
releasing the obligations of Subordinate Creditors hereunder (i) change the
manner, place or terms of payment or change or extend the time of payment of, or
renew or alter, the Senior Debt or the security therefor, or otherwise amend in
any manner the Management Agreement, the Note, the Loan Agreement or any
document executed in connection therewith; (ii) exercise or refrain from
exercising any rights against Borrower, Purchaser and others; (iii) apply any
sums by whomsoever paid or however realized to the Senior Debt; (iv) sell,
exchange, release, surrender, realize upon or otherwise deal with in any manner
and in any order any property whatsoever and by whomsoever at any time pledged
or mortgaged to secure, or howsoever securing, any Senior Debt; (v) release
anyone liable in any manner for the payment or collection of any Senior Debt;
and (vi) settle or compromise all or any part of the Senior Debt, and
subordinate the payment of any part of the Senior Debt to the payment of any
other indebtedness (including any other part of the Senior Debt).  No
invalidity, irregularity or unenforceability of all or any part of the Senior
Debt or of any of the Senior Liens shall affect, impair or be a defense to this
Agreement.

     4.   Subordinate Creditors jointly and severally represent and warrant that
no liens, security interests or assignments exist to secure any Subordinated
Debt other than the Permitted Subordinated Liens, and agree that no further
liens, security interests or assignments will arise or will be taken in the
future to secure any Subordinated Debt.  Without limiting the foregoing,
Subordinate Creditors hereby agree (a) that Subordinate Creditors will not
enforce the Subordinate Liens without the prior written consent of Senior


                                          6

<PAGE>

Creditor and (b) that the Subordinate Liens, to the extent enforceable, will be
enforceable by Senior Creditor. All amounts, whether in the form of cash,
proceeds, checks, drafts, orders or other instruments for the payment of money,
recovered with respect to any property of Borrower subject to the Subordinate
Liens by the enforcement of the Subordinate Liens shall immediately upon receipt
thereof by either Subordinate Creditor be paid over and delivered in the form
received, but with any necessary endorsements or instruments required for
payment to Senior Creditor, and, until so delivered shall not be commingled with
any other funds or property but shall be held by such Subordinate Creditor upon
an express trust for the benefit of Senior Creditor.

     5.   Subordinate Creditors do hereby expressly subordinate and make second,
junior and inferior any and all liens, rights, powers, titles and interests of
Subordinate Creditors under, pursuant to or by virtue of the Subordinate Liens
to all liens, rights, titles and interests of Senior Creditor under, pursuant to
or by virtue of the Senior Liens, and Subordinate Creditors agree that all
liens, rights, titles and interests of the Senior Liens shall be unconditionally
first, prior and superior to any and all liens, rights, powers, titles and
interests of Subordinate Creditors under, pursuant to or by virtue of the
Subordinate Liens. Subordinate Creditors further agree that any and all liens,
rights, titles and interests of Subordinate Creditors under, pursuant to or by
virtue of the Subordinate Liens shall be and remain expressly subject and
subordinate to any renewal, extension, refinancing, consolidation, modification
or supplement of the liens, rights, titles and interests of the Senior Liens, as
well as any and all increases thereof.

     6.   Subordinate Creditors, their successors or assigns or any other legal
holder of the Subordinated Debt shall not acquire by subrogation, contract or
otherwise any lien upon or other estate, right or interest in any property
(including but not limited to any which may arise in respect to real estate
taxes, assessments or other governmental charges) which is or may be prior in
right to the Senior Liens or any renewal, extension, refinancing, consolidation,
modification or supplement thereof.

     7.   Subordinate Creditors, their successors or assigns or any other legal
holder of the Subordinated Debt hereby assign and release to the legal holder of
the Senior Debt:

          (i)  all of their right, title, interest or claim, if any, in and to
               the proceeds of all policies of insurance covering any property
               for application upon the indebtedness secured by or other
               disposition thereof in accordance with the provisions of the
               Senior Liens;

          (ii) all of their right, title and interest or claim, if any, in and
               to all awards or other compensation made for any taking of any
               part of any property covered by the Senior Liens to be applied
               upon the indebtedness secured by or disposed of in accordance
               with the provisions of the Senior Liens.


                                          7

<PAGE>

In the event that following any such application and disposition of the
insurance proceeds and condemnation award and other compensation, any balance
remains, then, except as Borrower and Subordinate Creditors may otherwise agree,
such excess shall be made payable to the joint order of Subordinate Creditors
and Borrower or their successors or assigns. If the legal holder of the Senior
Liens shall at any time release to Borrower any such insurance proceeds or
condemnation award for the purpose of restoration, such release shall not be
deemed to be an additional advance under the Senior Liens nor shall it otherwise
be deemed to be in violation of any restriction of this instrument upon the
amount permitted to be secured by Senior Liens and to which the Subordinate
Liens are subordinate.

     8.   The Subordinate Liens shall be and the same are hereby are and shall
continue subject and subordinate to any and all leases upon all or any part of
any property covered by the Senior Liens and to which the Senior Liens shall now
be or shall hereafter have been made subject and subordinate.

     9.   Subordinate Creditors represent to Senior Creditor that the
Subordinated Debt is in good standing and in full force and effect and no
breaches or defaults exist thereunder which have not been cured or waived, that
all accrued interest on the Subordinate Notes has been paid in full through
September 25, 1997 and that the aggregate outstanding principal balance of the
Subordinate Notes on this date is $2,250,000.

     10.  This Agreement extends to and covers all amounts due on the Senior
Debt both before and after any filing of any Proceeding by or against Borrower
or Purchaser, and Senior Creditor shall be entitled to amounts accruing on the
Senior Debt from the date of filing of said Proceeding to the date of full and
final payment of the Senior Debt.

     11.  No part of the Subordinated Debt or any instrument evidencing or
securing the same has been heretofore transferred or assigned, and Subordinate
Creditors will not transfer or assign any part of the Subordinated Debt nor any
instrument evidencing the same while the Senior Debt remains unpaid.
Subordinate Creditors shall promptly deliver to Senior Creditor any instrument
evidencing the Subordinated Debt, including without limitation, the Subordinate
Notes and the Subordinate Guarantees for Senior Creditor to hold for the term of
this Agreement.

     12.  In the event of a breach by any party hereto of any of the provisions
of this Agreement, or in the event any representation or warranty contained
herein or furnished to Senior Creditor by any party hereto shall prove to have
been false when made, Senior Creditor shall have all rights provided to it under
law or equity, including without limitation the right to sue the breaching party
or parties to recover damages suffered by Senior Creditor as a result of such
breach, and the right to obtain injunctive relief.

     13.  Subordinate Creditors shall give, execute and deliver any notice,
statement, instrument, document, agreement or other papers, and shall permit
Senior Creditor, upon request, to make any notation or  endorsement upon any
promissory note or other instrument or documents evidencing or securing the
Subordinated Debt, that may be


                                          8

<PAGE>

necessary or desirable, or that Senior Creditor any reasonably request, in order
to create, preserve or validate the rights of Senior Creditor hereunder, to
enable Senior Creditor to exercise or enforce its rights hereunder, or otherwise
to effect the purposes of this Agreement.

     14.  This Agreement is a continuing one, and all Senior Debt to which it
applies or may apply under the terms hereof shall conclusively be presumed to
have been created in reliance hereon.

     15.  Borrower hereby agrees to pay upon demand all attorneys' fees and
expenses reasonably incurred by Senior Creditor in connection with the
enforcement of its rights under this Agreement.

     16.  Subordinate Creditors and Borrower agree that, if at any time all or
any part of any payment previously applied by Senior Creditor to the Senior Debt
is or must be returned by Senior Creditor--or recovered from Senior
Creditor--for any reason (including the order of any bankruptcy court), this
Agreement shall automatically be reinstated to the same effect, as if the prior
application had not been made, and, in addition, Borrower hereby agrees to
indemnify Senior Creditor against, and to save and hold Senior Creditor harmless
from any required return by Senior Creditor--or recovery from Senior
Creditor--of any such payments because of its being deemed preferential under
applicable bankruptcy, receivership or insolvency laws, or for any other reason.

     17.  Each Subordinate Creditor acknowledges that he has received a copy and
is familiar with the terms of and conditions of the Note, the Loan Agreement,
the Management Agreement and the other Loan Documents, and that each Subordinate
Creditor approves all such terms and conditions and consents to the execution
and delivery thereof and of this Agreement by Borrower and Purchaser, and to the
performance of each thereof by Borrower and Purchaser.

     18.  All notices, requests and other communications to any party hereunder
shall be in writing (including facsimile transmission or similar writing) and
shall be given to such party at its address or facsimile number set forth below
or such other address or facsimile number as such party may hereafter specify by
notice to the other party in accordance with this Section 18.  Each such notice,
request or other communication shall be deemed given on the second business day
after mailing; PROVIDED that actual notice, however and from whomever given or
received, shall always be effective on receipt.

     19.  This Agreement shall not be changed orally but shall be changed only
by agreement in writing signed by Subordinate Creditors and Senior Creditor
(without any necessity for notice to or consent by Borrower or Purchaser, which
are expressly WAIVED by Borrower and Purchaser).  No course of dealing between
the parties, no usage of trade and no parole or extrinsic evidence of any nature
shall be used to supplement or modify any of the terms or provisions of this
Agreement.

     20.  This Agreement may be signed in any number of counterparts, each of
which shall be an original, with the same effect as if the signatures thereto
and hereto were upon the same instrument.  This Agreement constitutes the entire
agreement and understanding among the parties hereto and supersedes any and all
prior agreements and understandings, oral or written, relating to the subject
matter hereof and thereof.

     21.  The provisions of this Agreement are severable.  The invalidity, in
whole or in part, of any provision of this Agreement shall not affect the
validity or enforceability of any other of its provisions.  If one or more
provisions hereof shall be declared invalid or unenforceable, the remaining
provisions shall remain in full force and effect and shall be construed in the
broadest possible manner to effectuate the purposes hereof.

     22.  This Agreement shall be deemed to have been made in the State of
California and the validity, construction, interpretation, and enforcement
hereof, and the rights of the parties hereto, shall be determined under,
governed by, and construed in accordance with the internal laws of the State of
California, without regard to principles of conflicts of law.

     23.  (a)  Each controversy, dispute or claim between the parties arising
out of or relating to this Agreement, which controversy, dispute or claim is not
settled in writing within thirty (30) days after the "CLAIM DATE" (defined as
the date on which a party subject to this Agreement gives written notice to all
other parties that a controversy, dispute or claim exists), will be settled by a
reference proceeding in California in accordance with the provisions of Section
638 ET SEQ. of the California Code of Civil Procedure, or their


                                          10

<PAGE>

successor section ("CCP"), which shall constitute the exclusive remedy for the
settlement of any controversy, dispute or claim concerning this Agreement,
including whether such controversy, dispute or claim is subject to the reference
proceeding and except as set forth above, the parties waive their rights to
initiate any legal proceedings against each other in any court or jurisdiction
other than Los Angeles County (the "COURT").  The referee shall be a retired
Judge of the Court selected by mutual agreement of the parties, and if they
cannot so agree within forty-five (45) days after the Claim Date, the referee
shall be promptly selected by the Presiding Judge of the Court (or his or her
representative).  The referee shall be appointed to sit as a temporary judge,
with all of the powers for a temporary judge, as authorized by law, and upon
selection should take and subscribe to the oath of office as provided for in
Rule 244 of the California Rules of Court (or any subsequently enacted Rule).
Each party shall have one peremptory challenge pursuant to CCP Section 170.6.
The referee shall (i) be requested to set the matter for hearing within sixty
(60) days after the Claim Date and (ii) try any and all issues of law or fact
and report a statement of decision upon them, if possible, within ninety (90)
days of the Claim Date.  Any decision rendered by the referee will be final,
binding and conclusive and judgment shall be entered pursuant to CCP Section 644
in any court in the State of California having jurisdiction.  Any party may
apply for a reference proceeding at any time after thirty (30) days following
notice to any other party of the nature of the controversy, dispute or claim, by
filing a petition for a hearing and/or trial.  All discovery permitted by this
Agreement shall be completed no later than fifteen (15) days before the first
hearing date established by the referee.  The referee may extend such period in
the event of a party's refusal to provide requested discovery for any reason
whatsoever, including, without limitation, legal objections raised to such
discovery or unavailability of a witness due to absence or illness.  No party
shall be entitled to "priority" in conducting discovery.  Depositions may be
taken by either party upon seven (7) days written notice, and request for
production or inspection of documents shall be responded to within ten (10) days
after service.  All disputes relating to discovery which cannot be resolved by
the parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Superior Court is empowered to issue temporary and/or provisional
remedies, as appropriate.

          (b)  Except as expressly set forth in this Agreement, the referee
shall determine the manner in which the reference proceeding is conducted
including the time and place of all hearings, the order of presentation of
evidence, and all other questions that arise with respect to the course of the
reference proceeding.  All proceedings and hearings conducted before the
referee, except for trial, shall be conducted without a court reporter except
that when any party so requests, a court reporter will be used at any hearing
conducted before the referee.  The party making such a request shall have the
obligation to arrange for and pay for the court reporter.  The costs of the
court reporter at the trial shall be borne equally by the parties.

          (c)  The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the


                                          11

<PAGE>

reference proceeding.  The referee shall be empowered to enter equitable as well
as legal relief, to provide all temporary and/or provisional remedies and to
enter equitable orders that will be binding upon the parties.  The referee shall
issue a single judgment at the close of the reference proceeding which shall
dispose of all of the claims of the parties that are the subject of the
reference.  The parties hereto expressly reserve the right to contest or appeal
from the final judgment or any appealable order or appealable judgment entered
by the referee.  The parties hereto expressly reserve the right to findings of
fact, conclusions of laws, a written statement of decision, and the right to
move for a new trial or a different judgment, which new trial, if granted, is
also to be a reference proceeding under this provision.

          (d)  In the event that the enabling legislation which provides for
appointment of a referee is repealed (and no successor statute is enacted), any
dispute between the parties that would otherwise be determined by the reference
procedure herein described will be resolved and determined by arbitration.  The
arbitration will be conducted by a retired judge of the Court, in accordance
with the California Arbitration Act, Section 1280 through Section 1294.2 of the
CCP as amended from time to time.  The limitations with respect to discovery as
set forth hereinabove shall apply to any such arbitration proceeding.

                               SUBORDINATION AGREEMENT


     This SUBORDINATION AGREEMENT (this "AGREEMENT"), dated as of September 25,
1997, is entered into by and among JAYARATNAM JAYAKUMAR, an individual
("SUBORDINATE CREDITOR"), PROSPECT MEDICAL HOLDINGS, INC., a Delaware
corporation ("BORROWER"), and IMPERIAL BANK, a California banking corporation
("SENIOR CREDITOR"), with reference to the following facts:

                                   R E C I T A L S

     A.   Borrower, Sierra Medical Management Inc., a Delaware corporation,
Sinnadurai E. Moorthy, M.D., Karunyan Arulanantham, and Subordinate Creditor,
are concurrently herewith entering into that certain Agreement and Plan of
Reorganization, dated as of September 23, 1997 (the "REORGANIZATION AGREEMENT").

     B.   Pursuant to the terms of the Reorganization Agreement, Borrower is
concurrently herewith executing and delivering to Subordinate Creditor a
Subordinated Promissory Note, dated as of even date herewith, 1997 (as it may
have been renewed, extended or rearranged, "SUBORDINATE NOTE"), in the original
principal sum of Two Hundred Fifty Thousand Dollars ($250,000). All liens,
security interests and assignments now or hereafter securing payment or
performance of the Subordinate Note are herein called "SUBORDINATE LIENS."

     C.   Borrower has previously executed and delivered to Senior Creditor that
certain Secured Revolving Note, dated July 3, 1997 (as it may have been renewed,
extended and rearranged, the "NOTE"), in the original principal sum of Ten
Million Dollars ($10,000,000).  The Note has been issued pursuant to that
certain Revolving Credit Agreement of even date with the Note (as it may have
been amended, supplemented or restated, the "LOAN AGREEMENT") between Borrower
and Senior Creditor.  All liens, security interests and assignments now or
hereafter securing payment or performance of the Note and/or the Loan Agreement
are herein called "SENIOR LIENS."  The Senior Liens include, without limitation,
the security instruments described on EXHIBIT A, attached hereto and
incorporated herein.

     D.   Borrower has requested that Senior Creditor make a loan under the Loan
Agreement to Borrower, which Borrower shall use to, among other things, fund its
obligations owing to Subordinate Creditor under the Reorganization Agreement. 
As a condition to its making such loan to Borrower, Senior Creditor has required
that Borrower's obligations under the Subordinate Note and the Reorganization
Agreement, and the Subordinate Liens securing any of the same, be subordinated
to Borrower's indebtedness under the Loan Agreement and the Note, the Senior
Liens securing same.

     E.   The parties hereto now hereby agree to subordinate the lien position,
payment and performance of the Subordinate Note, the Reorganization Agreement
and the 


                                          1
<PAGE>

Subordinate Liens to the payment and performance of the Note, the Loan Agreement
and the Senior Liens, all as set forth in the succeeding provisions of this
Agreement (which shall control over any conflicting or inconsistent recitals
above).

                                 A G R E E M E N T S

     In consideration of the premises and the mutual agreements herein set
forth, Borrower, Subordinate Creditor and Senior Creditor hereby agree as
follows:

     1.   All initially capitalized terms used but not defined in this Agreement
shall have the meanings given to such terms in the Loan Agreement.  In addition,
as used in this Agreement, the following terms shall have the respective
meanings indicated:

          "SENIOR DEBT" shall mean all Debt now existing or hereafter created of
Borrower to Senior Creditor, whether direct or indirect, primary or secondary,
joint or several, fixed or contingent and whether originally payable to Senior
Creditor or any third Person and subsequently acquired by or assigned to Senior
Creditor, and whether evidenced by note, application for or agreement for
reimbursement of advance under letter of credit, open account, overdraft,
indorsement, surety agreement, guaranty or otherwise, including, without
limitation, all indebtedness evidenced by the Note and all renewals, extensions,
rearrangements, refundings and modifications of the Note, and all Debt arising
under or incurred pursuant to the Loan Agreement and any other documents
executed or delivered in connection therewith.  The Senior Debt shall include
amounts accruing subsequent to the filing of any bankruptcy, receivership,
insolvency or like petition.  Without limiting the generality of the foregoing,
Senior Debt shall include all obligations for fees, to indemnify, to reimburse
for expenses and to reimburse for advances (whether for the payment of taxes,
insurance premiums, the preservation or protection of property or the title
thereto or for any other reason).

          "SUBORDINATED DEBT" shall mean all Debt now existing or hereafter
created of Borrower to Subordinate Creditor, whether direct or indirect, primary
or secondary, joint or several, fixed or contingent and whether originally
payable to Subordinate Creditor or to a third Person and subsequently acquired
by Subordinate Creditor, and whether evidenced by note, application for or
agreement for reimbursement of advance under letter of credit, open account,
overdraft, indorsement, surety agreement, guaranty or otherwise, including,
without limitation, all Debt evidenced by the Subordinate Note and all renewals,
extensions, rearrangements, refundings and modifications of the Subordinate Note
and any other documents executed or delivered in connection therewith.

     2.   (a) Unless and until all Senior Debt shall have been fully paid and
satisfied and the obligation of Senior Creditor to make any further loans or
advances to Borrower shall have ceased and terminated, Subordinate Creditor will
not, except as otherwise provided in SECTION 2(B) hereof, (i) ask, demand, sue
for, take or receive, or retain, from Borrower or any other Person, by setoff or
in any other manner, payment of all or any part of the Subordinated Debt, (ii)
forgive, cancel or discharge, or permit to be converted into 


                                          2
<PAGE>

any evidence of equity or ownership, any of the Subordinated Debt, (iii) ask,
demand or receive any security for the Subordinated Debt in addition to the
security described on EXHIBIT B attached hereto and incorporated herein
("PERMITTED SUBORDINATED LIENS"), (iv) amend the Subordinate Note or any other
document existing in connection with the Subordinated Debt, or (v) declare the
Subordinated Debt due and payable by reason of any default or for any other
reason, or bring or join with any creditor in bringing any proceeding against
Borrower under any bankruptcy, reorganization, readjustment or arrangement of
debt, suspension of payments, receivership, liquidation or insolvency or similar
law or statute now or hereafter in effect ("PROCEEDINGS").  Subordinate Creditor
hereby directs Borrower to make, and Borrower hereby agrees to make, such prior
payment of the Senior Debt to Senior Creditor.

          (b)  Notwithstanding the foregoing, Borrower may make regularly
scheduled payments (but no prepayments) of interest and principal due on the
Subordinate Note, PROVIDED that on the date of the proposed payment, no Event of
Default has occurred and is continuing or will result from the making of such
payment.  Upon the occurrence of an Event of Default and upon written notice
thereof given to Borrower and Subordinate Creditor by Senior Creditor or its
representative, no further payments shall be made by Purchaser with respect to
the principal of or interest on the Subordinate Note.

     3.   (a)  Upon any distribution of the assets of Borrower in connection
with any dissolution, winding up, liquidation or reorganization of Borrower
(whether in Proceedings or upon an assignment for the benefit of creditors or
any other marshalling of the assets and liabilities of Borrower or otherwise),
Senior Creditor shall first be entitled to receive payment in full of all Senior
Debt before Subordinate Creditor shall be entitled to receive any payment in
respect of the Subordinated Debt.  Upon any such dissolution, winding up,
liquidation or reorganization, any payment or distribution of assets of Borrower
of any kind or character, whether in cash, property or securities, to which
Subordinate Creditor would be entitled except for the provisions of this
Agreement (including any such payment or distribution which may be payable or
deliverable by virtue of the provisions of any securities which are subordinated
as junior in right of payment to the Subordinated Debt) shall be made by the
liquidating trustee or agent or other Persons making such payment or
distribution (whether a trustee in bankruptcy, a receiver or liquidating trustee
or otherwise) (a "PAYING PARTY"), or if received by Subordinate Creditor, by
Subordinate Creditor, directly to Senior Creditor, to the extent necessary to
pay in full the Senior Debt remaining unpaid, after giving effect to any
concurrent payment or distribution to Senior Creditor.  Subordinate Creditor
hereby authorizes and directs each Paying Party to pay over to Senior Creditor
upon demand by Senior Creditor, all such payments or distributions without the
necessity of any inquiry as to the status or balance of the Senior Debt, and
without further notice to or consent of Subordinate Creditor.  In furtherance of
the foregoing, but not by way of limitation thereof, in the event Borrower is
subject to any Proceeding, with the result that Borrower is excused from the
obligation to pay all or part of the interest otherwise payable in respect of
the Senior Debt during the period subsequent to the commencement of any such
Proceeding, Subordinate Creditor agrees that all or such part of such interest, 


                                          3
<PAGE>

as the case may be, shall be payable out of, and to that extent diminish and be
at the expense of, reorganization dividends or distributions in respect of the
Subordinated Debt.

          (b)  Subordinate Creditor hereby irrevocably authorizes and empowers
Senior Creditor to demand, sue for, collect and receive every such payment or
distribution and give acquittance therefor, to execute, sign, endorse, transfer
and deliver any and all receipts and instruments, and to file claims and take
such other proceedings, all in the name of Subordinate Creditor, or otherwise,
as Senior Creditor may deem necessary or advisable for the enforcement of this
Agreement, but Senior Creditor has no obligation to do so.  Subordinate Creditor
hereby (i) agrees duly and promptly to take such action as may be required by
Senior Creditor to collect the Subordinated Debt for the account of Senior
Creditor and/or to file appropriate proofs of claim in respect of the
Subordinated Debt, (ii) authorizes and empowers Senior Creditor to vote the full
amount of the Subordinated Debt in any bankruptcy, reorganization or similar
proceeding affecting Borrower and in any meeting of creditors of Borrower, (iii)
agrees to execute and deliver to Senior Creditor or its representatives on
demand such powers of attorney, proofs of claim and other instruments as may be
requested by Senior Creditor or its representatives in order to enable Senior
Creditor to enforce any and all claims upon or with respect to the Subordinated
Debt, to collect and receive any and all such payments or distributions which
may be payable or deliverable at any time upon or with respect to the
Subordinated Debt, and to vote the full amount of the Subordinated Debt in any
proceeding or meeting referred to in clause (ii) of this subparagraph (b).

          (c)  In the event any payment or distribution of assets of Borrower of
any kind or character, whether in cash, property or securities, and whether or
not pursuant to any dissolution, winding up, liquidation or reorganization, not
permitted by or in accordance with the provisions of this Agreement shall be
received by Subordinate Creditor, such payment or distribution to Subordinate
Creditor shall not be commingled with other funds and shall be held in trust for
the benefit of, and shall be paid over or delivered to, Senior Creditor, or to
its representative, in precisely the form received (except for the endorsement
or assignment of Subordinate Creditor where necessary).  In the event of any
failure by Subordinate Creditor to make any such endorsement or assignment,
Senior Creditor is hereby irrevocably authorized to make same.

          (d)  Notwithstanding the terms and provisions of this Agreement,
Subordinate Creditor shall not be entitled to be subrogated to any of the rights
of Senior Creditor against Borrower or any other Person or any Senior Liens or
other collateral security or rights of offset held by Senior Creditor for the
payment of the Senior Debt, nor shall Subordinate Creditor have any right of
indemnity, reimbursement or contribution against Borrower or any other Person
for any payment of the Senior Debt, and Subordinate Creditor hereby expressly
waives each and every such right of subrogation, indemnity, reimbursement and
contribution.

          (e)  The provisions of this Agreement are and are intended solely for
the purpose of defining the relative rights of Subordinate Creditor and Senior
Creditor, and are 


                                          4
<PAGE>

solely for the benefit of Senior Creditor and may not be relied upon or enforced
by any party other than Senior Creditor, and nothing contained in this Agreement
is intended to or shall impair the obligation of Borrower, which is
unconditional and absolute, to pay to Subordinate Creditor the principal of and
interest on the Subordinated Debt as and when the same shall become due and
payable in accordance with its terms (except as otherwise provided in Section
2(b) hereof), or to affect the relative rights of Subordinate Creditor and
creditors of Borrower other than Senior Creditor.

          (f)  Senior Creditor may, at any time and from time to time, without
the consent of or notice to Subordinate Creditor, and without impairing or
releasing the obligations of Subordinate Creditor hereunder (i) change the
manner, place or terms of payment or change or extend the time of payment of, or
renew or alter, the Senior Debt or the security therefor, or otherwise amend in
any manner the Note, the Loan Agreement or any document executed in connection
therewith; (ii) exercise or refrain from exercising any rights against Borrower
and others; (iii) apply any sums by whomsoever paid or however realized to the
Senior Debt; (iv) sell, exchange, release, surrender, realize upon or otherwise
deal with in any manner and in any order any property whatsoever and by
whomsoever at any time pledged or mortgaged to secure, or howsoever securing,
any Senior Debt; (v) release anyone liable in any manner for the payment or
collection of any Senior Debt; and (vi) settle or compromise all or any part of
the Senior Debt, and subordinate the payment of any part of the Senior Debt to
the payment of any other indebtedness (including any other part of the Senior
Debt).  No invalidity, irregularity or unenforceability of all or any part of
the Senior Debt or of any of the Senior Liens shall affect, impair or be a
defense to this Agreement.

     4.   Subordinate Creditor represents and warrants that no liens, security
interests or assignments exist to secure any Subordinated Debt other than the
Permitted Subordinated Liens, and agree that no further liens, security
interests or assignments will arise or will be taken in the future to secure any
Subordinated Debt.  Without limiting the foregoing, Subordinate Creditor hereby
agrees (a) that Subordinate Creditor will not enforce the Subordinate Liens
without the prior written consent of Senior Creditor and (b) that the
Subordinate Liens, to the extent enforceable, will be enforceable by Senior
Creditor. All amounts, whether in the form of cash, proceeds, checks, drafts,
orders or other instruments for the payment of money, recovered with respect to
any property of Borrower subject to the Subordinate Liens by the enforcement of
the Subordinate Liens shall immediately upon receipt thereof by Subordinate
Creditor be paid over and delivered in the form received, but with any necessary
endorsements or instruments required for payment to Senior Creditor, and, until
so delivered shall not be commingled with any other funds or property but shall
be held by Subordinate Creditor upon an express trust for the benefit of Senior
Creditor.

     5.   Subordinate Creditor does hereby expressly subordinate and make
second, junior and inferior any and all liens, rights, powers, titles and
interests of Subordinate Creditor under, pursuant to or by virtue of the
Subordinate Liens to all liens, rights, titles and interests of Senior Creditor
under, pursuant to or by virtue of the Senior Liens, and Subordinate Creditor
agrees that all liens, rights, titles and interests of the Senior Liens shall 


                                          5
<PAGE>

be unconditionally first, prior and superior to any and all liens, rights,
powers, titles and interests of Subordinate Creditor under, pursuant to or by
virtue of the Subordinate Liens. Subordinate Creditor further agrees that any
and all liens, rights, titles and interests of Subordinate Creditor under,
pursuant to or by virtue of the Subordinate Liens shall be and remain expressly
subject and subordinate to any renewal, extension, refinancing, consolidation,
modification or supplement of the liens, rights, titles and interests of the
Senior Liens, as well as any and all increases thereof.
 
     6.   Subordinate Creditor, his successors or assigns or any other legal
holder of the Subordinated Debt shall not acquire by subrogation, contract or
otherwise any lien upon or other estate, right or interest in any property
(including but not limited to any which may arise in respect to real estate
taxes, assessments or other governmental charges) which is or may be prior in
right to the Senior Liens or any renewal, extension, refinancing, consolidation,
modification or supplement thereof.

     7.   Subordinate Creditors, his successors or assigns or any other legal
holder of the Subordinated Debt hereby assigns and releases to the legal holder
of the Senior Debt:

          (i)    all of his right, title, interest or claim, if any, in and to
                 the proceeds of all policies of insurance covering any
                 property for application upon the indebtedness secured by or
                 other disposition thereof in accordance with the provisions of
                 the Senior Liens;

          (ii)   all of his right, title and interest or claim, if any, in and
                 to all awards or other compensation made for any taking of any
                 part of any property covered by the Senior Liens to be applied
                 upon the indebtedness secured by or disposed of in accordance
                 with the provisions of the Senior Liens.

In the event that following any such application and disposition of the
insurance proceeds and condemnation award and other compensation, any balance
remains, then, except as Borrower and Subordinate Creditor may otherwise agree,
such excess shall be made payable to the joint order of Subordinate Creditor and
Borrower or their successors or assigns. If the legal holder of the Senior Liens
shall at any time release to Borrower any such insurance proceeds or
condemnation award for the purpose of restoration, such release shall not be
deemed to be an additional advance under the Senior Liens nor shall it otherwise
be deemed to be in violation of any restriction of this instrument upon the
amount permitted to be secured by Senior Liens and to which the Subordinate
Liens are subordinate.

     8.   The Subordinate Liens shall be and the same are hereby are and shall
continue subject and subordinate to any and all leases upon all or any part of
any property covered by the Senior Liens and to which the Senior Liens shall now
be or shall hereafter have been made subject and subordinate.


                                          6

     9.   Subordinate Creditor represents to Senior Creditor that the
Subordinated Debt is in good standing and in full force and effect and no
breaches or defaults exist thereunder which have not been cured or waived, that
all accrued interest on the Subordinate Note has been paid in full through
September 25, 1997 and that the aggregate outstanding principal balance of the
Subordinate Note on this date is $250,000.

     10.  This Agreement extends to and covers all amounts due on the Senior
Debt both before and after any filing of any Proceeding by or against Borrower,
and Senior Creditor shall be entitled to amounts accruing on the Senior Debt
from the date of filing of said Proceeding to the date of full and final payment
of the Senior Debt.

     11.  No part of the Subordinated Debt or any instrument evidencing or
securing the same has been heretofore transferred or assigned, and Subordinate
Creditor will not transfer or assign any part of the Subordinated Debt nor any
instrument evidencing the same while the Senior Debt remains unpaid. 
Subordinate Creditors shall promptly deliver to Senior Creditor any instrument
evidencing the Subordinated Debt, including without limitation, the Subordinate
Note for Senior Creditor to hold for the term of this Agreement.

     12.  In the event of a breach by any party hereto of any of the provisions
of this Agreement, or in the event any representation or warranty contained
herein or furnished to Senior Creditor by any party hereto shall prove to have
been false when made, Senior Creditor shall have all rights provided to it under
law or equity, including without limitation the right to sue the breaching party
or parties to recover damages suffered by Senior Creditor as a result of such
breach, and the right to obtain injunctive relief.

     13.  Subordinate Creditor shall give, execute and deliver any notice,
statement, instrument, document, agreement or other papers, and shall permit
Senior Creditor, upon request, to make any notation or  endorsement upon any
promissory note or other instrument or documents evidencing or securing the
Subordinated Debt, that may be necessary or desirable, or that Senior Creditor
any reasonably request, in order to create, preserve or validate the rights of
Senior Creditor hereunder, to enable Senior Creditor to exercise or enforce its
rights hereunder, or otherwise to effect the purposes of this Agreement.

     14.  This Agreement is a continuing one, and all Senior Debt to which it
applies or may apply under the terms hereof shall conclusively be presumed to
have been created in reliance hereon.

     15.  Borrower hereby agrees to pay upon demand all attorneys' fees and
expenses reasonably incurred by Senior Creditor in connection with the
enforcement of its rights under this Agreement.

     16.  Subordinate Creditor and Borrower agree that, if at any time all or
any part of any payment previously applied by Senior Creditor to the Senior Debt
is or must be returned by Senior Creditor--or recovered from Senior
Creditor--for any reason (including 


                                          7
<PAGE>

the order of any bankruptcy court), this Agreement shall automatically be
reinstated to the same effect, as if the prior application had not been made,
and, in addition, Borrower hereby agrees to indemnify Senior Creditor against,
and to save and hold Senior Creditor harmless from any required return by Senior
Creditor--or recovery from Senior Creditor--of any such payments because of its
being deemed preferential under applicable bankruptcy, receivership or
insolvency laws, or for any other reason.

     17.  Subordinate Creditor acknowledges that he has received a copy and is
familiar with the terms of and conditions of the Note, the Loan Agreement, and
the other Loan Documents, and that Subordinate Creditor approves all such terms
and conditions and consents to the execution and delivery thereof and of this
Agreement by Borrower and to the performance of each thereof by Borrower.

     18.  All notices, requests and other communications to any party hereunder
shall be in writing (including facsimile transmission or similar writing) and
shall be given to such party at its address or facsimile number set forth below
or such other address or facsimile number as such party may hereafter specify by
notice to the other party in accordance with this Section 18.  Each such notice,
request or other communication shall be deemed given on the second business day
after mailing; PROVIDED that actual notice, however and from whomever given or
received, shall always be effective on receipt.

     20.  This Agreement may be signed in any number of counterparts, each of
which shall be an original, with the same effect as if the signatures thereto
and hereto were upon the same instrument.  This Agreement constitutes the entire
agreement and understanding among the parties hereto and supersedes any and all
prior agreements and understandings, oral or written, relating to the subject
matter hereof and thereof.

     21.  The provisions of this Agreement are severable.  The invalidity, in
whole or in part, of any provision of this Agreement shall not affect the
validity or enforceability of any other of its provisions.  If one or more
provisions hereof shall be declared invalid or unenforceable, the remaining
provisions shall remain in full force and effect and shall be construed in the
broadest possible manner to effectuate the purposes hereof.

     22.  This Agreement shall be deemed to have been made in the State of
California and the validity, construction, interpretation, and enforcement
hereof, and the rights of the parties hereto, shall be determined under,
governed by, and construed in accordance with the internal laws of the State of
California, without regard to principles of conflicts of law.

     23.  (a)  Each controversy, dispute or claim between the parties arising
out of or relating to this Agreement, which controversy, dispute or claim is not
settled in writing within thirty (30) days after the "CLAIM DATE" (defined as
the date on which a party subject to this Agreement gives written notice to all
other parties that a controversy, dispute or claim exists), will be settled by a
reference proceeding in California in accordance with the provisions of Section
638 ET SEQ. of the California Code of Civil Procedure, or their successor
section ("CCP"), which shall constitute the exclusive remedy for the settlement
of any controversy, dispute or claim concerning this Agreement, including
whether such controversy, dispute or claim is subject to the reference
proceeding and except as set forth above, the parties waive their rights to
initiate any legal proceedings against each other in any court or jurisdiction
other than Los Angeles County (the "COURT").  The referee shall be a retired
Judge of the Court selected by mutual agreement of the parties, and if they
cannot so agree within forty-five (45) days after the Claim Date, the referee
shall be promptly selected by the Presiding Judge of the Court (or his or her
representative).  The referee shall be appointed to sit as a temporary judge,
with all of the powers for a temporary judge, as authorized by law, and upon
selection should take and subscribe to the oath of office as provided for in
Rule 244 of the California Rules of Court (or any subsequently enacted Rule). 
Each party shall have one peremptory challenge pursuant to CCP Section 170.6. 
The referee shall (i) be requested to set the matter for hearing within sixty
(60) days after the Claim Date and (ii) try any and all issues of law or fact
and report a statement of decision upon them, if possible, within ninety (90)
days of the Claim Date.  Any decision rendered by the referee will be final,
binding and conclusive and judgment shall be entered pursuant to CCP Section 644
in any court in the State of California having jurisdiction.  Any party may
apply for a reference proceeding at any time after thirty (30) days following
notice to any other party of the nature of the controversy, dispute or claim, by
filing a petition for a hearing and/or trial.  All discovery permitted by this
Agreement shall be completed no later than fifteen (15) days before the first
hearing date established by the referee.  The referee may extend such period in
the event of a party's refusal to 


                                          9
<PAGE>

provide requested discovery for any reason whatsoever, including, without
limitation, legal objections raised to such discovery or unavailability of a
witness due to absence or illness.  No party shall be entitled to "priority" in
conducting discovery.  Depositions may be taken by either party upon seven (7)
days written notice, and request for production or inspection of documents shall
be responded to within ten (10) days after service.  All disputes relating to
discovery which cannot be resolved by the parties shall be submitted to the
referee whose decision shall be final and binding upon the parties.  Pending
appointment of the referee as provided herein, the Superior Court is empowered
to issue temporary and/or provisional remedies, as appropriate.

          (b)  Except as expressly set forth in this Agreement, the referee
shall determine the manner in which the reference proceeding is conducted
including the time and place of all hearings, the order of presentation of
evidence, and all other questions that arise with respect to the course of the
reference proceeding.  All proceedings and hearings conducted before the
referee, except for trial, shall be conducted without a court reporter except
that when any party so requests, a court reporter will be used at any hearing
conducted before the referee.  The party making such a request shall have the
obligation to arrange for and pay for the court reporter.  The costs of the
court reporter at the trial shall be borne equally by the parties.

          (c)  The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties.  The referee shall issue a single judgment at the
close of the reference proceeding which shall dispose of all of the claims of
the parties that are the subject of the reference.  The parties hereto expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee.  The parties hereto
expressly reserve the right to findings of fact, conclusions of laws, a written
statement of decision, and the right to move for a new trial or a different
judgment, which new trial, if granted, is also to be a reference proceeding
under this provision.

          (d)  In the event that the enabling legislation which provides for
appointment of a referee is repealed (and no successor statute is enacted), any
dispute between the parties that would otherwise be determined by the reference
procedure herein described will be resolved and determined by arbitration.  The
arbitration will be conducted by a retired judge of the Court, in accordance
with the California Arbitration Act, Section 1280 through Section 1294.2 of the
CCP as amended from time to time.  The limitations with respect to discovery as
set forth hereinabove shall apply to any such arbitration proceeding.

                  1.1.2.    All of the terms and conditions contained in the
Master Lease are incorporated herein as terms and conditions of the sublease

Medical Director.  GROUP shall be solely responsible for payment of any and all
compensation, payroll taxes, fringe benefits, disability insurance, workers'
compensation insurance and any other benefits of all such individuals.

          4.2.    GROUP shall not enter into any agreements with Participating
Providers unless such Participating Providers have: (i) current unrestricted
licenses to practice their respective professions in the State of California and
(ii) current unrestricted Federal Drug Enforcement Agency ("DEA") numbers.  In
addition, where GROUP contracts with individual physicians, such physicians
shall have medical staff membership at the hospitals required by the Plans and
where GROUP contracts with licensed clinics and medical groups, at least one
primary care physician practicing at each clinic or medical group shall have
medical staff membership at the hospitals required by the Plans.  GROUP further
agrees to establish procedures to ensure that Participating Providers meet these
requirements on an ongoing basis.  Manager shall reasonably cooperate with and
assist GROUP to meet its obligations under this Section 4.2; provided however,
that GROUP acknowledges and agrees that it shall retain ultimate responsibility
for meeting such obligations.

          4.3.    GROUP acknowledges and agrees that it is solely responsible
for making all required reports to the Medical Board of California under Section
805 of the California Business and Professions Code and the National
Practitioner Data Bank.

          4.4.    GROUP shall, at its sole cost and expense, procure and
maintain at all times during the term of this Agreement comprehensive general
and professional liability insurance covering all activities of GROUP directly
or indirectly relating to GROUP, each policy in a minimum amount of
$1,000,000.00 per occurrence and $3,000,000.00 in the aggregate.  The
aforedescribed comprehensive general and professional liability insurance shall
be issued by a company or companies authorized to do business in California with
a financial rating of at least A:12 or better in "Best's Key Rating Guide" or
its equivalent.  In the event GROUP procures a "claims made" policy as
distinguished from an "occurrence" policy, GROUP shall procure and maintain at
its sole cost and expense, prior to termination of such insurance, "tail"
coverage to continue and extend coverage complying with this Agreement after the
end of the "claims made" policy.  Upon reasonable request from Manager, GROUP
shall cause to be issued to Manager proper certificates of insurance, evidencing
that the foregoing provisions of this Agreement have been complied with, and
said certificates shall provide that prior to any cancellation or change in the
underlying insurance during the policy period, the insurance carrier shall first
give thirty (30) calendar days written notice to Manager.

          4.5.    Subject to the terms and conditions of Sections 3.1.6.3 and
3.1.6.4 herein, GROUP shall, at its sole cost and expense, including, but not
limited to, the payment of all salaries, benefits, medical malpractice
insurance, employ or contract with such physicians as shall be reasonably
necessary for the conduct of the Practice.

          4.6.    GROUP shall ensure that Participating Providers procure and
maintain professional liability insurance with minimum coverage amounts of
$1,000,000.00 per occurrence and $3,000,000.00 in the aggregate.  GROUP shall
ensure that any Participating Provider who procures insurance required hereunder
on a "claims made" rather than an "occurrences" form will obtain either extended
reporting insurance coverage ("tail coverage") with liability limits equal to
those most recently in effect prior to the day of termination of such
Participating Provider's contract with GROUP, or will enter into such other
arrangements as shall reasonably assure the maintenance of coverage for such
Provider, GROUP, and Manager against the risk of loss in respect of professional
services rendered by such provider while this Agreement was in effect and for a
period of not less than seven (7) years after the date of termination of this
Agreement.

          4.7.    GROUP acknowledges and agrees that it shall reasonably assist
and cooperate with Manager to meet all of Manager's obligations under this
Agreement, including approval of agreements and provision of information.  GROUP
acknowledges and agrees that Manager shall have no liability for GROUP's failure
to pay any and all of GROUP's debts and expenses.

any obligation required hereunder which failure amounts to gross negligence,
fraud or an illegal act on the part of Manager, and such default shall continue
for sixty (60) calendar days after written notice from GROUP specifying the

Agreement shall terminate automatically and immediately upon the expiration of
said sixty (60) calendar day period; provided, however, that if the obligation
which Manager fails to perform is other than the failure to make payment of
money, and greater than sixty (60) calendar days are required to perform said
obligation, then such party shall not be in default of this Agreement and the
Agreement shall not terminate as provided hereinabove if such party commences
performance within said sixty day period and diligently pursues said obligation
to completion.

                  5.2.3. Either party may terminate this Agreement for cause at

make a general assignment for the benefit of creditors, file a petition or
answer seeking reorganization or arrangement with creditors, or take advantage
of any bankruptcy, insolvency, reorganization, moratorium or other law for the
benefit of creditors or if any order, judgment, or decree shall be entered by
any court of competent jurisdiction on the application of a creditor or
otherwise adjudicating either party bankrupt or approving a petition seeking
reorganization of either party or appointment of a receiver, trustee or
liquidator of either party of all or a substantial part of its assets, and such
order, judgment or decree shall continue stayed and in effect for sixty (60)
calendar days after its entry, termination shall be effective automatically and
immediately upon the occurrence of the foregoing.

          5.3.    JEOPARDY.  In the event the performance by either party hereto
of any term, covenant, condition or provision of this Agreement should be
determined by a state or federal court or governmental agency to be in violation

                                          14
<PAGE>

deemed illegal ("Jeopardy Event"), then the parties shall use their best efforts
to meet forthwith and attempt to negotiate an amendment to this Agreement to
remove or negate the effect of the Jeopardy Event.  In the event the parties are
unable to negotiate such an amendment within thirty (30) days following written
notice by either party of the Jeopardy Event, then either party may terminate
this Agreement immediately upon written notice.

such a decision in accordance with applicable law in any court having
jurisdiction thereof.

the essence of this Agreement, the parties specifically reserve the right to 
seek a judicial temporary restraining order, preliminary injunction, or other 
similar short term equitable relief, and grant the arbitrator the right to 
make a final determination of the parties' rights, including whether to make 
permanent or dissolve such court order.

hereunder (including, without limitation, arbitration), the prevailing party in

order to give effect to the transactions contemplated by this Agreement and the
intentions of the parties hereto.

          15.15.  RIGHTS CUMULATIVE.  The various rights and remedies herein
granted to Manager or GROUP shall be cumulative and in addition to any other
rights Manager or GROUP, respectively, may be entitled to under law.  The

1395x (V)(1)(I) of Title 42 of the United States Code, with respect to any

3.   OPTION PRICE.  The purchase price for the Option (the "Option Price") is

receipt of such payment.

4.   EXERCISE OF OPTION.

<PAGE>

          (a)  There shall be one arbitrator.  If the parties shall fail to
select a mutually acceptable arbitrator within ten (10) days after the demand
for arbitration is mailed, then the parties stipulate to arbitration before a
retired judge sitting on the Los Angeles, California, Judicial Arbitration
Mediation Services (JAMS) panel.

          (b)  The substantive law of the State of California shall be applied
by the arbitrator.

          (c)  Arbitration shall take place in Los Angeles, California, unless
Group and a majority of the other parties otherwise agree.  As soon as
reasonably practicable, a hearing with respect to the dispute or matter to be
resolved shall be conducted by the arbitrator.  As soon as reasonably
practicable thereafter, the arbitrator shall arrive at a final decision, which
shall be reduced to writing, signed by the arbitrator and mailed to each of the
parties and their legal counsel.

          (d)  All decisions of the arbitrator shall be final, binding and
conclusive on the parties and shall constitute the only method of resolving
disputes or matters subject to arbitration pursuant to this Agreement.  The
arbitrator or a court of appropriate jurisdiction may issue a writ of execution
to enforce the arbitrator's judgment.  Judgment may be entered upon such a
decision in accordance with applicable law in any court having jurisdiction
thereof.

          (e)  Notwithstanding the foregoing, because time is of the essence of
this Agreement, the parties specifically reserve the right to seek a judicial
temporary restraining order, preliminary injunction, or other similar short term
equitable relief, and grant the arbitrator the right to make a final
determination of the parties' rights, including whether to make permanent or
dissolve such court order.

          (f)  Notwithstanding the foregoing, any and all arbitration
proceedings are conditional upon such proceedings being covered within the
parties' respective risk insurance policies.

     9.15 ATTORNEYS' FEES.  Should any of the parties hereto institute any
action or procedure to enforce this Agreement or any provision hereof (including
without limitation, arbitration), or for damages by reason of any alleged breach
of this Agreement or of any provision hereof, or for a declaration of rights
hereunder (including, without limitation, by means of arbitration), the
prevailing party in any such action or proceeding shall be entitled to receive
from the other party all costs and expenses, including without limitation
reasonable attorneys' fees, incurred by the prevailing party in connection with
such action or proceeding.

     9.16 FURTHER ASSURANCES.  The parties shall take such actions and execute
and deliver such further documentation as may reasonably be required in order to
give effect to the transactions contemplated by this Agreement and the
intentions of the parties hereto.

                                       9

     9.17 RIGHTS CUMULATIVE.  The various rights and remedies herein granted to
the respective parties hereto shall be cumulative and in addition to any other
rights any such party may be entitled to under law.  The exercise of one or more
rights or remedies by a party shall not impair the right of such party to
exercise any other right or remedy, at law or equity.

     9.18 CONFLICTS. In the event that any provision contained herein shall
conflict with the Amended and Restated Credit Succession Agreement, the
provision of the Amended and Restated Credit Succession Agreement shall control
and such conflicting provision herein shall be of no further force or effect.

     IN WITNESS WHEREOF, Group, Prospect Medical Group, and Sierra Medical

               2.2  RIGHTS AND REMEDIES.  All of the rights, benefits, remedies,
privileges and claims of Assignor with respect to the Transaction Documents
(collectively, the "RIGHTS AND REMEDIES"), including, without limitation, (i)
all rights to monies or payments owing to Assignor under the Transaction

          3.   RIGHT AND REMEDIES GENERALLY.  Prior to the occurrence of a

Rights and Remedies diligently and in good faith.  Effective from and after the
occurrence of a Default, Assignor hereby irrevocably authorizes and empowers
Bank, in Bank's own discretion, to assert as Bank may deem proper, either
directly or on behalf of Assignor, any of the Rights and Remedies which Assignor
may from time to time have under the Transaction Documents, and to receive and
collect all damages, awards and other monies resulting therefrom and to apply
the same on account of any of the Guaranteed Obligations.

accordance with the terms of the Security Agreement until the Security Agreement
is terminated in accordance with its terms.

          6.   ATTORNEY-IN-FACT.  Assignor hereby irrevocably makes,

such Rights and Remedies and to collect such damages, awards and other monies
and to apply them in the manner set forth hereinabove, and (b) to sign the name
of Assignor on any documents which need to be executed, recorded, or filed, and

order to protect Bank's interests in the Transaction Documents.  Assignor agrees
that neither Bank, nor any of its designees or attorneys-in-fact, will be liable
for any act of commission or omission, or for any error of judgment or mistake
of fact or law with respect to the exercise of the power of attorney granted
under this Section 6, other than as a result of its or their gross negligence or
wilful misconduct.  The power of attorney granted under this Section 6 is
coupled with an interest and shall be irrevocable until all of the Guaranteed
Obligations have been paid in full, the Guaranty terminated, and Assignor's
duties under this Assignment have been discharged in full.

with a copy of any notice sent by Assignor in connection with the Transaction
Documents, concurrently with the sending of any such notice.  Assignor shall not
waive, amend, alter or modify any of the Rights and Remedies in any material
respect without the prior written consent of Bank.  Assignor shall not, without
Bank's prior written consent, amend, alter, modify or terminate any of the
Transaction Documents, or waive any of the provisions thereof, or do or permit
any act in contravention thereof.

          8.   ASSIGNOR TO REMAIN LIABLE.  Notwithstanding the foregoing,
Assignor expressly acknowledges and agrees that it shall remain liable under the
Transaction Documents to observe and perform all of the conditions and
obligations in the Transaction Documents which Assignor is bound to observe and
perform, and that neither this Assignment, nor any action taken pursuant hereto,
shall cause Bank to be under any obligation or liability in any respect
whatsoever to observe or perform any of the

                                          3

          14.  JUDICIAL REFERENCE.

               14.1   REFERENCE PROCEEDING.  Other than (i) nonjudicial
foreclosure and all matters in connection therewith regarding security interests
in real or personal property; or (ii) the appointment of a receiver, or the
exercise of other provisional remedies (any and all of which may be initiated
pursuant to applicable law), each controversy, dispute or claim between the
parties arising out of or relating to this Assignment, which controversy,
dispute or claim is not settled in writing within thirty (30) days after the
"CLAIM DATE" (defined as the date on which either Assignor or Bank gives written
notice to the other that a controversy, dispute or claim exists), will be
settled by a reference proceeding in California in accordance with the
provisions of Section 638 ET SEQ. of the California Code of Civil Procedure, or
their successor section ("CCP"), which shall

                                          4
<PAGE>

constitute the exclusive remedy for the settlement of any controversy, dispute
or claim concerning this Assignment, including whether such controversy, dispute
or claim is subject to the reference proceeding and except as set forth above,
the parties waive their rights to initiate any legal proceedings against each
other in any court or jurisdiction other than the Superior Court in Los Angeles
County (the "COURT").  The referee shall be a retired Judge of the Court
selected by mutual agreement of the parties, and if they cannot so agree within
forty-five (45) days after the Claim Date, the referee shall be promptly
selected by the Presiding Judge of the Court (or his representative).  The
referee shall be appointed to sit as a temporary judge, with all of the powers
for a temporary judge, as authorized by law, and upon selection should take and
subscribe to the oath of office as provided for in Rule 244 of the California
Rules of Court (or any subsequently enacted Rule).  Each party shall have one
peremptory challenge pursuant to CCP Section 170.6.  The referee shall (a) be
requested to set the matter for hearing within sixty (60) days after the date of
selection of the referee and (b) try any and all issues of law or fact and
report a statement of decision upon them, if possible, within ninety (90) days
of the Claim Date.  Any decision rendered by the referee will be final, binding
and conclusive and judgment shall be entered pursuant to CCP Section 644 in any
court in the State of California having jurisdiction.  Any party may apply for a
reference proceeding at any time after thirty (30) days following notice to any
other party of the nature of the controversy, dispute or claim, by filing a
petition for a hearing and/or trial.  All discovery permitted by this Assignment
shall be completed no later than fifteen (15) days before the first hearing date
established by the referee.  The referee may extend such period in the event of
a party's refusal to provide requested discovery for any reason whatsoever,
including, without limitation, legal objections raised to such discovery or
unavailability of a witness due to absence or illness.  No party shall be
entitled to "priority" in conducting discovery.  Depositions may be taken by
either party upon seven (7) days written notice, and request for production or
inspection of documents shall be responded to within ten (10) days after
service.  All disputes relating to discovery which cannot be resolved by the
parties shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Court is empowered to issue temporary and/or provisional remedies,
as appropriate.

               14.2   MANNER OF REFERENCE PROCEEDING.  Except as expressly set
forth in this Assignment, the referee shall determine the manner in which the
reference proceeding is conducted including the time and place of all hearings,
the order of presentation of evidence, and all other questions that arise with
respect to the course of the reference proceeding.  All proceedings and hearings
conducted before the referee, except for trial, shall be conducted without a
court reporter except that when any party so requests, a court reporter will be
used at any hearing conducted before the referee.  The party making such a
request shall have the obligation to arrange for and pay for the court reporter.
The costs of the court reporter at the trial shall be borne equally by the
parties.

               14.3   DUTIES OF REFEREE.  The referee shall be required to
determine all issues in accordance with existing case law and the statutory laws
of the State of California.  The rules of evidence applicable to proceedings at
law in the State of California


                                          5
<PAGE>

will be applicable to the reference proceeding.  The referee shall be empowered
to enter equitable as well as legal relief, to provide all temporary and/or
provisional remedies and to enter equitable orders that will be binding upon the
parties.  The referee shall issue a single judgment at the close of the
reference proceeding which shall dispose of all of the claims of the parties
that are the subject of the reference.  The parties hereto expressly reserve the
right to contest or appeal from the final judgment or any appealable order or
appealable judgment entered by the referee.  The parties hereto expressly
reserve the right to findings of fact, conclusions of laws, a written statement
of decision, and the right to move for a new trial or a different judgment,
which new trial, if granted, is also to be a reference proceeding under this
provision.

               14.4   ARBITRATION ALTERNATIVE.  In the event that the enabling
legislation which provides for appointment of a referee is repealed (and no
successor statute is enacted), any dispute between the parties that would
otherwise be determined by the reference procedure herein described will be
resolved and determined by arbitration.  The arbitration will be conducted by a
retired judge of the Court, in accordance with the California Arbitration Act,
Section 1280 through Section 1294.2 of the CCP as amended from time to time.
The limitations with respect to discovery as set forth hereinabove shall apply
to any such arbitration proceeding.

          EXECUTED as of the date first above written.

a notice at least five (5) calendar days before the date of the sale in a
newspaper of general circulation, if one exists, in the county in which the sale

                    (e)  Manager may, in its own name, or in the name of a
designee or nominee, credit bid and purchase at any public sale;

                    (f)  Physician Group shall pay all Expenses; and

                    (g)  Any portion of the Secured Obligations which remains
unpaid after disposition of the Collateral as provided above shall be paid
immediately by Physician Group.  Any excess which exists after disposition of
the Collateral and payment in full of the Secured Obligations shall be returned
promptly, without interest and subject to the rights of third persons, to
Physician Group by Manager.

               8.2  FURTHER DOCUMENTATION.  Upon the exercise by Manager of any
power, right, privilege, or remedy pursuant to this Security Agreement which
requires any consent, approval, registration, qualification, or authorization of
any Governmental Authority, Physician Group agrees to execute and deliver, or

instruments, assignments, and other documents and papers that Manager or any
purchaser of the Collateral may be required to obtain for such governmental
consent, approval, registration, qualification, or authorization.

               8.3  CUMULATIVE REMEDIES; WAIVERS.  The rights and remedies of
Manager under this Security Agreement, the Management Agreement, and all other
agreements contemplated hereby and thereby shall be cumulative.  Manager shall
have all other rights and remedies not inconsistent herewith as provided under
the Code, by law, or in equity.  No exercise by Manager of any one right or
remedy shall be deemed an election of remedies, and no waiver by Manager of any
default on Physician Group's part shall be deemed a continuing waiver of any

               10.1 SUCCESSORS AND ASSIGNS.  This Security Agreement shall bind
and inure to the benefit of the respective successors and assigns of Physician
Group and Manager; PROVIDED, HOWEVER, that Physician Group may not assign this
Security Agreement nor delegate any of its duties hereunder without Manager's
prior written consent and any prohibited assignment or delegation shall be
absolutely void.  No consent by Manager to an assignment by Physician Group
shall release Physician Group from the Secured Obligations.  Manager may assign
this Security Agreement and delegate its duties hereunder, if any, from time to
time to its lender or lenders or to its parent's lender or lenders, without
prior notice to, or the consent of, Physician Group, and Physician Group agrees
to recognize such lender or lenders as Manager's assignee under this Security
Agreement.

               10.2 NO PRESUMPTION AGAINST ANY PARTY.  Neither this Security
Agreement nor any uncertainty or ambiguity herein shall be construed or resolved
against Manager or Physician Group, whether under any rule of construction or
otherwise.  On the contrary, this Security Agreement has been reviewed by each
of the parties and their counsel and shall be construed and interpreted
according to the ordinary meaning of the words used so as to accomplish fairly
the purposes and intentions of all parties hereto.

               10.3 AMENDMENTS AND WAIVERS.  Any provision of this Security
Agreement may be amended or waived if, but only if, such amendment or waiver is
in writing and is signed by the party asserted to be bound thereby, and then
such amendment or waiver shall be effective only in the specific instance and
specific purpose for which given.

               10.4 COUNTERPARTS; INTEGRATION; EFFECTIVENESS.  This Security
Agreement may be signed in any number of counterparts, each of which shall be an
original, with the same effect as if the signatures thereto and hereto were upon
the same instrument.  This Security Agreement constitutes the entire agreement
and understanding among the parties hereto and supersedes any and all prior
agreements and understandings, oral or written, relating to the subject matter
hereof.  This Security Agreement shall become effective when executed by each of
the parties hereto and delivered to Manager.

          11.  GOVERNING LAW.  This Security Agreement shall be deemed to have
been made in the State of California and the validity, construction,
interpretation, and enforcement hereof, and the rights of the parties hereto,
shall be determined under, governed by, and construed in accordance with the
internal laws of the State of California.

          12.  NO VIOLATION OF APPLICABLE LAW.  To the extent that any lien or
security interest on any Asset(s) granted by Physician Group herein violates any
applicable Health Care Law, the grant of such lien or security interest on such
Asset(s) shall be automatically null and void; provided however, that to the
extent such lien or security interest at any time hereafter no longer violates
any applicable Health Care Law, then such


                                          8
<PAGE>

lien or security interest shall automatically and without any further action
attach and become fully effective at that time (giving effect to any retroactive
effect to any change in applicable law or regulation); and, provided further,
that the liens or security interests on other Asset(s) granted by Physician
Group herein that do not violate any applicable Health Care Law shall remain at
all times in full force and effect.

          1.   FOR VALUE RECEIVED, PROSPECT MEDICAL SYSTEMS, INC., a Delaware

HOLDINGS, INC., a Delaware corporation ("PAYEE"), on or before the Maturity Date
unless sooner accelerated in accordance with the terms hereof, the principal sum
of Seven Hundred Thousand Dollars ($700,000).  As used herein the term "MATURITY
DATE" has the meaning given to such term in that certain Revolving Credit
Agreement, dated as of July 3, 1997, between Payee and Imperial Bank (as amended
or restated from time to time, the "CREDIT AGREEMENT").

          2.   This Secured Promissory Note shall bear interest at a per annum
rate equal to six percent (6%).  All computations of interest shall be
calculated on the basis of a year of three hundred sixty-five (365) days for the
actual days elapsed.  Interest shall accrue from the date of this Secured
Promissory Note to the date of repayment of this Secured Promissory Note in

United States of America and in immediately available funds to the holder hereof
("HOLDER") at Holder's office or to such other address as Holder may from time

          4.   In no event shall the interest rate and other charges hereunder
exceed the highest rate permissible under any law which a court of competent
jurisdiction shall, in a final determination, deem applicable hereto.  In the
event that such a court determines that Holder has received interest and other
charges hereunder in excess of the highest rate applicable hereto, such excess
shall be deemed received on account of, and shall automatically be applied to
reduce, the principal balance hereof, and the provisions hereof shall be deemed
amended to provide for the highest permissible rate.  If there is no principal
balance outstanding, Holder shall refund to Maker such excess.

          5.   The unpaid principal balance hereof together with all accrued but
unpaid interest thereon shall be all due and payable upon (i) failure by Maker
to pay any installment of principal or interest due hereunder when due,
(ii) commencement of any proceeding by or against Maker under any bankruptcy or
insolvency laws, or (iii) the occurrence of an "Event of Default" under the
Credit Agreement.

                          REPLACEMENT SECURED REVOLVING NOTE


$12,500,000                                             Los Angeles, California
                                                               February 6, 1998


          1.   FOR VALUE RECEIVED, PROSPECT MEDICAL HOLDINGS, INC., a Delaware
corporation, ("MAKER"), promises to pay to the order of IMPERIAL BANK, a
California banking corporation ("PAYEE"), on or before the Maturity Date, the
principal sum of Twelve Million Five Hundred Thousand Dollars ($12,500,000), or
such lesser sum as shall equal the aggregate outstanding principal amount of the
Revolving Loans made by Payee to Maker pursuant to the Agreement (as defined
below).

          2.   This Replacement Secured Revolving Note (this "NOTE") shall bear
interest at a per annum rate equal to the Prime Rate PLUS the Applicable Margin
(the "LENDING RATE").  As used herein "PRIME RATE" means the rate of interest
announced by Payee at its corporate headquarters as its prime rate and which
serves as the basis upon which effective rates of interest are calculated for
those loans making reference thereto.  The Prime Rate is determined by Payee
from time to time as a means of pricing credit extensions to some customers and
is neither directly tied to some external rate of interest or index nor
necessarily the lowest rate of interest charged by Payee at any given time for
any particular class of customers or credit extensions.  All computations of
interest shall be calculated on the basis of a year of three hundred sixty (360)
days for the actual days elapsed.  In the event that the Prime Rate announced
is, from time to time, changed, adjustment in the rate of interest payable
hereunder shall be made as of 12:01 a.m. (California time) on the effective date
of the change in the Prime Rate.  Interest shall accrue from the date of this
Note to the date of repayment of this Note in accordance with the provisions
hereof.  Maker shall pay all accrued but unpaid interest on the Revolving Loans,
in arrears, on the first Business Day of each and every month.  As used herein,
"BUSINESS DAY" means any day other than a Saturday, a Sunday, or a day on which
commercial banks in the City of Los Angeles, California are authorized or
required by law or executive order or decree to close.

          3.   Maker hereby authorizes Payee to record in its books and records
the date and amount of each Revolving Loan, and of each payment of principal
made by Maker, and Maker agrees that all such notations shall, in the absence of
manifest error, be conclusive as to the matters so noted; PROVIDED, HOWEVER, any
failure by Payee to make such notation with respect to any Revolving Loan or
payment thereof shall not limit or otherwise affect Maker's obligations under
the Agreement or this Note.

          4.   If any payment due hereunder or under the Agreement shall not be
paid when due (whether at the stated maturity, by acceleration or otherwise), in
addition to and not in substitution of any other rights and remedies which Payee
may have with respect to such nonpayment, the entire principal balance owing
hereunder shall bear interest at the Lending Rate PLUS five hundred (500) basis
points until such overdue payment is paid in full.  In addition, interest, Bank
Expenses and Fees due hereunder or under the Agreement

<PAGE>

not paid when due shall bear interest at the Lending Rate PLUS five hundred
(500) basis points until such overdue payment is paid in full.

          5.   If any payment due hereunder, whether for principal, interest, or
otherwise, is not paid on or before the tenth day after the date such payment is
due, in addition to and not in substitution of any of Payee's other rights and
remedies with respect to such nonpayment, Maker shall pay to Payee, a late
payment fee ("LATE PAYMENT FEE") equal to five percent (5%) of the amount of
such overdue payment.  The Late Payment Fee shall be due and payable on the
eleventh day after the due date of the overdue payment with respect thereto.

          6.   Maker shall make all payments hereunder in lawful money of the
United States of America and in immediately available funds to Payee at Payee's
office located at 9920 South La Cienega Boulevard, Suite 628, Inglewood, CA
90301, Attention Lending Services Department; or to such other address as Payee
may from time to time specify by notice to Maker in accordance with the terms of
the Agreement.

          7.   In no event shall the interest rate and other charges hereunder
exceed the highest rate permissible under any law which a court of competent
jurisdiction shall, in a final determination, deem applicable hereto.  In the
event that such a court determines that Payee has received interest and other
charges hereunder in excess of the highest rate applicable hereto, such excess
shall be deemed received on account of, and shall automatically be applied to
reduce, the principal balance hereof, and the provisions hereof shall be deemed
amended to provide for the highest permissible rate.  If there is no principal
balance outstanding, Payee shall refund to Maker such excess.

          8.   This Note is the "Note" referred to in that certain Revolving
Credit Agreement, dated as of July 3, 1997, as amended by that certain Amendment
Number One, dated as of July 14, 1997, that certain Amendment Number Two, dated
as of September 25, 1997, and that certain Amendment Number Three, dated as of
even date herewith (as may be at any time hereafter further amended,
supplemented, or otherwise modified or restated, the "AGREEMENT"), by and
between Maker, as Borrower, and Payee, as Bank, and is governed by the terms
thereof.  Initially capitalized terms used but not defined herein shall have the
meanings assigned to such terms in the Agreement.  The Agreement, among other
things, contains provisions for acceleration of the maturity of this Note upon
the happening of certain stated events and also for prepayments on account of
principal of this Note prior to the maturity hereof upon the terms and
conditions specified in the Agreement.

          9.   This Note is secured by the Liens granted to Payee under the Loan
Documents.

          10.  Maker hereby waives presentment for payment, notice of dishonor,
protest and notice of protest.


                                          2
<PAGE>

          11.  This Note shall be governed by and construed in accordance with
the internal laws of the State of California without regard to principles of
conflicts of laws.

          12.  (a)  Other than (i) nonjudicial foreclosure and all matters in
connection therewith regarding security interests in real or personal property;
or (ii) the appointment of a receiver, or the exercise of other provisional
remedies (any and all of which may be initiated pursuant to applicable law),
each controversy, dispute or claim between Maker and Payee arising out of or
relating to this Note, which controversy, dispute or claim is not settled in
writing within thirty (30) days after the "CLAIM DATE" (defined as the date on
which either Maker or Payee gives written notice to the other that a
controversy, dispute or claim exists), will be settled by a reference proceeding
in California in accordance with the provisions of Section 638 ET SEQ. of the
California Code of Civil Procedure, or their successor section ("CCP"), which
shall constitute the exclusive remedy for the settlement of any controversy,
dispute or claim concerning this Note, including whether such controversy,
dispute or claim is subject to the reference proceeding and except as set forth
above, Maker and Payee waive their rights to initiate any legal proceedings
against each other in any court or jurisdiction other than the Superior Court in
the County where any real property collateral is located, or Los Angeles County,
if none (the "COURT").  The referee shall be a retired Judge of the Court
selected by mutual agreement of Maker and Payee, and if they cannot so agree
within forty-five (45) days after the Claim Date, the referee shall be promptly
selected by the Presiding Judge of the Court (or his or her representative).
The referee shall be appointed to sit as a temporary judge, with all of the
powers for a temporary judge, as authorized by law, and upon selection should
take and subscribe to the oath of office as provided for in Rule 244 of the
California Rules of Court (or any subsequently enacted Rule).  Each party shall
have one peremptory challenge pursuant to CCP Section 170.6.  The referee shall
(i) be requested to set the matter for hearing within sixty (60) days after the
Claim Date and (ii) try any and all issues of law or fact and report a statement
of decision upon them, if possible, within ninety (90) days of the Claim Date.
Any decision rendered by the referee will be final, binding and conclusive and
judgment shall be entered pursuant to CCP Section 644 in any court in the State
of California having jurisdiction.  Any party may apply for a reference
proceeding at any time after thirty (30) days following notice to any other
party of the nature of the controversy, dispute or claim, by filing a petition
for a hearing and/or trial.  All discovery permitted by herein shall be
completed no later than fifteen (15) days before the first hearing date
established by the referee.  The referee may extend such period in the event of
a party's refusal to provide requested discovery for any reason whatsoever,
including, without limitation, legal objections raised to such discovery or
unavailability of a witness due to absence or illness.  No party shall be
entitled to "priority" in conducting discovery.  Depositions may be taken by
either party upon seven (7) days written notice, and request for production or
inspection of documents shall be responded to within ten (10) days after
service.  All disputes relating to discovery which cannot be resolved by Maker
and Payee shall be submitted to the referee whose decision shall be final and
binding upon the parties.  Pending appointment of the referee as provided
herein, the Superior Court is empowered to issue temporary and/or provisional
remedies, as appropriate.

<PAGE>

               (b)  Except as expressly set forth herein, the referee shall
determine the manner in which the reference proceeding is conducted including
the time and place of all hearings, the order of presentation of evidence, and
all other questions that arise with respect to the course of the reference
proceeding.  All proceedings and hearings conducted before the referee, except
for trial, shall be conducted without a court reporter except that when any
party so requests, a court reporter will be used at any hearing conducted before
the referee.  The party making such a request shall have the obligation to
arrange for and pay for the court reporter.  The costs of the court reporter at
the trial shall be borne equally by the parties.

               (c)  The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties.  The referee shall issue a single judgment at the
close of the reference proceeding which shall dispose of all of the claims of
the parties that are the subject of the reference.  Maker and Payee expressly
reserve the right to contest or appeal from the final judgment or any appealable
order or appealable judgment entered by the referee.  Maker and Payee expressly
reserve the right to findings of fact, conclusions of laws, a written statement
of decision, and the right to move for a new trial or a different judgment,
which new trial, if granted, is also to be a reference proceeding under this
provision.

               (d)  In the event that the enabling legislation which provides
for appointment of a referee is repealed (and no successor statute is enacted),
any dispute between Maker and Payee that would otherwise be determined by the
reference procedure herein described will be resolved and determined by
arbitration.  The arbitration will be conducted by a retired judge of the Court,
in accordance with the California Arbitration Act,


                                          4
<PAGE>

Section 1280 through Section 1294.2 of the CCP as amended from time to time.
The limitations with respect to discovery as set forth hereinabove shall apply
to any such arbitration proceeding.

          13.  This Note replaces that certain Secured Revolving Note, dated as
of July 3, 1997, in the amount of Ten Million Dollars ($10,000,000), executed by
Maker to the order of Payee, and continues the obligations of Maker incurred
thereunder.

          IN WITNESS WHEREOF, Maker has duly executed this Note as of the date
first above written.

opinion as promptly as practicable.  In either case, the determination so made

any mutual agreement with the Company with respect to Fair Value and as to any
selection of investment banking firms) shall be binding upon all such holders.

     6.   ADJUSTMENT OF EXERCISE PRICE, NUMBER OF SHARES AND NATURE OF

          (a)  EXERCISE PRICE:  ADJUSTMENT OF NUMBER OF SHARES.  The Exercise
Price shall be subject to adjustment from time to time as hereinafter provided.
Upon each adjustment of the Exercise Price, the Warrantholders shall thereafter

number of shares determined by multiplying the Exercise Price in effect
immediately prior to such adjustment by the number of shares purchasable
pursuant hereto immediately prior to such adjustment and dividing the product
thereof by the Exercise Price resulting from such adjustment.

          (b)  ADJUSTMENT OF EXERCISE PRICE UPON ISSUANCE OF COMMON STOCK.  If
and whenever after the date hereof the Company shall issue or sell Additional
Shares of Common Stock without consideration or for a consideration per share
less than the Exercise Price then in effect immediately prior to the issuance or
sale of such shares, then the Exercise Price in effect immediately prior to such
issuance or sale of such shares shall be reduced to the lesser of (a) the amount
of such consideration per share of Additional Shares so issued (with the
consideration being deemed to be $.01 per share for issuances for no
consideration), and (b) the Current Market Price of the Common Stock.

               No adjustment of the Exercise Price, however, shall be made in an
amount less than $.01 per share, but any such lesser adjustment shall be carried
forward and shall be made at the time and together with the next subsequent
adjustment which, together with any adjustments so carried forward, shall amount
to $.01 per share or more.

               The provisions of this Section 6(b) shall not apply to (x) any
Additional Shares of Common Stock which are distributed to holders of Common
Stock pursuant to a stock split for which an adjustment is provided for under
Section 6(f), or (y) the issuance of not to exceed 597,000 shares of Common
Stock which may hereafter be issued to employees, consultants or other vendors
of services pursuant to incentive plans or as compensation for their services.

          (c)  FURTHER PROVISIONS FOR ADJUSTMENT OF EXERCISE PRICE UPON ISSUANCE
OF ADDITIONAL SHARES OF COMMON STOCK AND CONVERTIBLE SECURITIES.  For purposes
of Section 6(b), the following provisions shall also be applicable:

               (i)    In case at any time on or after the date hereof, the
Company shall declare any dividend, or authorize any other distribution, upon
any stock of the Company of any class, payable in Additional Shares of Common
Stock or by the issuance of Convertible Securities, such declaration or
distribution shall be deemed to have been issued or sold (as of the record date)
without consideration and shall thereby cause an adjustment in the Exercise
Price as required by Section 6(b).


                                          6

               (ii)   (A)     In case at any time on or after the date hereof,
the Company shall in any manner issue or sell any Convertible Securities,
whether or not the rights to exchange or convert thereunder are immediately
exercisable, there shall be determined the price per share for which Additional
Shares of Common Stock are issuable upon the conversion or exchange thereof,
such determination to be made by dividing (a) the total amount received or
receivable by the Company as consideration for the issue or sale of such
Convertible Securities, plus the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the conversion or exchange
thereof by (b) the maximum aggregate number of Additional Shares of Common Stock
issuable upon conversion or exchange of all such Convertible Securities for such
minimum aggregate amount of additional consideration; and such issue or sale
shall be deemed to be an issue or sale for cash (as of the date of issue or sale
of such Convertible Securities) of such maximum number of Additional Shares of
Common Stock at the price per share so determined, and shall thereby cause an
adjustment in the Exercise Price, if such an adjustment is required by
Section 6(b) hereof.

                      (B)     If such Convertible Securities shall by their
terms provide for an increase or increases, with the passage of time, in the
amount of additional consideration, if any, payable to the Company, or in the
rate of exchange upon the conversion or exchange thereof, the adjusted Exercise
Price shall, upon any such increase becoming effective, be increased to such
Exercise Price as would have been in effect had the adjustments made upon the
issuance of such Convertible Securities been made upon the basis of (and the
total consideration received therefor) (a) the issuance of the number of shares
of Common Stock theretofore actually delivered upon the exercise of such
Convertible Securities, (b) the issuance of all Common Stock, all Convertible
Securities and all rights and options to purchase Common Stock issued after the
issuance of such Convertible Securities, and (c) the original issuance at the
time of such change of any such Convertible Securities then still outstanding;
PROVIDED, HOWEVER, that any such increase or increases shall not exceed, in the
aggregate, the amount of the original reduction of the Exercise Price
attributable to the Convertible Securities.

                      (C)     If any rights of conversion or exchange evidenced
by such Convertible Securities shall expire without having been exercised, the
adjusted Exercise Price shall forthwith be readjusted to such Exercise Price as
would have been in effect had an adjustment with respect to such Convertible
Securities been made on the basis that the only Additional Shares of Common
Stock issued or sold were those issued upon the conversion or exchange of such
Convertible Securities, and that they were issued or sold for the consideration
actually received by the Company upon such exercise, plus the consideration, if
any, actually received by the Company for the granting of such Convertible
Securities.

               (iii)  (A)     In case at any time on or after the date hereof,
the Company shall in any manner grant or issue any rights or options to
subscribe for, purchase or otherwise acquire Additional Shares of Common Stock,
whether or not such rights or options are immediately exercisable, except the
granting of employee stock options to


                                          7
<PAGE>

purchase one hundred thirty thousand (130,000) shares of the Company's Common
Stock per year, at an exercise price equal to the Current Market Price, and
except for: (x) four hundred seventy-seven thousand one hundred nineteen
(477,119) shares of Common Stock issuable upon exercise of those outstanding
employee stock options which are in existence as of the date hereof, (y) one
hundred and forty-seven thousand one hundred and forty-six (147,146) shares of
Common Stock issuable upon the exercise of warrants in existence as of the date
hereof, other than this Warrant, but including a warrant for 132,375 shares of
Common Stock issued to the Bank or its affiliate on July 3, 1997, as amended and
restated (the "Prior Warrant"), and issuable under certain other agreements of
the Company which agreements are in existence as of the date hereof and
(z) 35,000 shares of Common Stock reserved for issuance upon the exercise of
options granted by the Company in an acquisition permitted under the Loan
Agreement, as such shares of Common Stock are more fully set forth in Section
12(a) below, there shall be determined the price per share for which Additional
Shares of Common Stock are issuable upon the exercise of such rights or options,
such determination to be made by dividing (a) the total amount, if any, received
or receivable by the Company as consideration for the granting of such rights or
options, plus the minimum aggregate amount of additional consideration, if any,
payable to the Company upon the exercise of such rights or options if the
maximum number of Additional Shares were issued pursuant to such rights or
options for such minimum aggregate amount of additional consideration, by
(b) the maximum number of Additional Shares of Common Stock of the Company
issuable upon the exercise of all such rights or options for such minimum
aggregate amount of additional consideration; and the granting of such rights or
options shall be deemed to be an issue or sale for cash (as of the date of the
granting of such rights or options) of such maximum number of Additional Shares
of Common Stock at the price per share so determined, and shall thereby cause an
adjustment in the Exercise Price, if such an adjustment is required by
Section 6(b) hereof.

                      (B)     If such rights or options shall by their terms
provide for an increase or increases, with passage of time, in the amount of
additional consideration payable to the Company upon the exercise thereof, the
adjusted Exercise Price shall, upon any such increases becoming effective, be
increased to such Exercise Price as would have been in effect had the
adjustments made upon the issuance of such rights or options been made upon the
basis of (and the total consideration received therefor) (a) the issuance of the
number of shares of Common Stock theretofore actually delivered upon the
exercise of such rights or options, (b) the issuance of all Common Stock, all
rights and options and all Convertible Securities issued after the issuance of
such rights and options, and (c) the original issuance at the time of such
change of any such rights or options then still outstanding; PROVIDED, HOWEVER,
that any such increase or increases in the Exercise Price shall not exceed, in
the aggregate, the amount of the original reduction of the Exercise Price
attributable to the grant of such rights or options.

                      (C)     If any such rights or options shall expire without
having been exercised, the adjusted Exercise Price shall forthwith be readjusted
to such Exercise Price as would have been in effect had an adjustment with
respect to such rights or options been made on the basis that the only
Additional Shares of Common Stock so issued or sold


                                          8
<PAGE>

were those issued or sold upon the exercise of such rights or options and that
they were issued or sold for the consideration actually received by the Company
upon such exercise, plus the consideration, if any, actually received by the
Company for the granting of such rights or options.

               (iv)   (A)     In case at any time on or after the date hereof,
the Company shall grant any rights or options to subscribe for, purchase or
otherwise acquire Convertible Securities, there shall be determined the price
per share for which Additional Shares of Common Stock are issuable upon the
exchange or conversion of such Convertible Securities if such rights or options
were exercised, such determination to be made by dividing (a) the total amount,
if any, received or receivable by the Company as consideration for the issuance
of such rights or options, plus the minimum aggregate amount of additional
consideration, if any, payable to the Company upon the exercise of such rights
or options if the maximum number of Convertible Securities were issued pursuant
to such rights or options for such minimum aggregate amount of additional
consideration, plus the minimum aggregate amount of additional consideration, if
any, payable to the Company upon the exchange or conversion of such Convertible
Securities if the maximum number of Additional Shares were issued pursuant to
such Convertible Securities for such minimum aggregate amount of additional
consideration, by (b) the maximum aggregate number of Additional Shares of
Common Stock issuable upon the exchange or conversion of the Convertible
Securities for such minimum aggregate amount of additional consideration; and
the issue or sale of such rights or options shall be deemed to be an issue or
sale for cash (as of the date of the granting of such rights or options) of such
maximum number of Additional Shares of Common Stock at the price per share so
determined, and thereby shall cause an adjustment in the Exercise Price, if such
an adjustment is required by Section 6(b).

                      (B)     If such rights or options to subscribe for or
otherwise acquire Convertible Securities shall by their terms provide for an
increase or increases, with the passage of time, in the amount of additional
consideration payable to the Company upon the exercise, exchange or conversion
thereof, the adjusted Exercise Price shall, forthwith upon any such increase
becoming effective, be increased to such Exercise Price as would have been in
effect had the adjustments made upon the issuances of such rights or options
been made upon the basis of (and the total consideration received therefor)
(a) the issuance of the number of shares of Common Stock theretofore actually
delivered upon the exchange or conversion of such Convertible Securities,
(b) the issuances of all Common Stock and all rights, options and Convertible
Securities issued after the issuance of such rights and options, and (c) the
original issuances at the time of such change of any such rights, options and
Convertible Securities issued upon exercise of such rights or options which are
then still outstanding; provided, however, that any such increase or increases
shall not exceed, in the aggregate, the amount of the original reduction of the
Exercise Price attributable to the grant of such rights or options.

                      (C)     If any such rights, options or rights of
conversion or exchange of such Convertible Securities shall expire without
having been exercised, exchanged or converted, the adjusted Exercise Price shall
forthwith be readjusted to such


                                          9
<PAGE>

Exercise Price as would have been in effect had an adjustment been made with
respect to such rights, options or rights of conversion or exchange of such
Convertible Securities on the basis that the only Additional Shares of Common
Stock so issued or sold were those issued or sold upon the exercise of such
rights or options and exchange or conversion of such Convertible Securities and
that they were issued or sold for the consideration actually received by the
Company upon exercise of such rights and options and exchange or conversion of
such Convertible Securities, plus the consideration, if any, actually received
by the Company for the granting of such rights, options or Convertible
Securities.

               (v)    In any case where an adjustment has been made in the
Exercise Price upon the issuance of Convertible Securities or any rights or
options to purchase Convertible Securities or Additional Shares of Common Stock
pursuant to this Section 6(c), no further adjustment shall be made at the time
of the conversion of any such Convertible Securities or at the time of the
exercise of any such rights or options.

               (vi)   In case at any time on or after the issuance of this
Warrant any shares of Common Stock or Convertible Securities shall be issued or
sold for a consideration other than cash, the amount of the consideration other
than cash payable to the Company shall be deemed to be the Fair Value of such
consideration.  Whether or not the consideration so received is cash, the amount
thereof shall be determined after deducting therefrom any expenses incurred or
any underwriting commissions or concessions or discounts paid or allowed by the
Company in connection therewith.

               (vii)  In case at any time the Company shall fix a record date
of the holders of its Common Stock for the purpose of entitling them (a) to
receive a dividend or other distribution payable in Common Stock, Convertible
Securities or rights or options to purchase either thereof, or (b) to subscribe
for or purchase Common Stock, Convertible Securities or rights or options to
purchase either thereof, then such record date shall be deemed to be the date of
the issue or sale of the shares of Common Stock deemed, pursuant to this
Section 6(c), to have been issued or sold upon the declaration of such dividend
or the making of such other distribution or the date of the granting of such
right of subscription or purchase, as the case may be.

               (viii) The number of shares of Common Stock outstanding at any
given time shall not include shares owned or held by or for the account of the
Company, and the disposition of any such shares shall be considered an issue or
sale of Common Stock for the purposes of this Section 6(c).

          (d)  REORGANIZATION, RECLASSIFICATION, CONSOLIDATION, MERGER OR SALE.
If any capital reorganization or reclassification of the capital stock of the
Company, or any consolidation or merger of the Company with another corporation,
or the sale of all or substantially all of its assets to another corporation
shall be effected in such a way that holders of Common Stock shall be entitled
to receive cash, stock, securities or assets with respect to or in exchange for
Common Stock, then, as a condition of such reorganization, reclassification,
consolidation, merger or sale, lawful and adequate provisions shall be made


                                          10
<PAGE>

whereby the Warrantholders shall thereafter have the right to purchase and
receive upon the basis and upon the terms and conditions specified in this
Warrant upon exercise of this Warrant and in lieu of the shares of the Common
Stock of the Company immediately theretofore purchasable and receivable upon the
exercise of the rights represented hereby, such cash, shares of stock,
securities or assets as may be issued or payable with respect to or in exchange
for a number of outstanding shares of Common Stock equal to the number of shares
of such Common Stock immediately theretofore purchasable and receivable upon the
exercise of the rights represented hereby, and in any such case appropriate
provision shall be made with respect to the rights and interest of the
Warrantholders to the end that the provisions hereof (including, without
limitation, provisions for adjustments of the Exercise Price and of the number
of shares purchasable and receivable upon the exercise of this Warrant) shall
thereafter be applicable, as nearly as may be, in relation to any shares of
stock, securities or assets thereafter deliverable upon the exercise hereof.
The Company shall not effect any consolidation, merger or sale of all or
substantially all of the assets of the Company unless prior to or simultaneous
with the consummation thereof the successor corporation (if other than the
Company) resulting from such consolidation, merger or purchase of such assets
shall assume, by written instrument executed and mailed or delivered to the
Warrantholders, the obligation to deliver to such Warrantholders such cash (or
cash equivalent), shares of stock, securities or assets as, in accordance with
the foregoing provisions, the Warrantholders may be entitled to receive and
containing the express assumption of such successor corporation of the due and
punctual performance and observance of each provision of this Warrant to be
performed and observed by the Company and of all liabilities and obligations of
the Company hereunder; PROVIDED, HOWEVER, in the case of any consolidation or
merger of the Company with another corporation or the sale of all or
substantially all of its assets to another corporation effected in such a manner
that the holders of Common Stock shall be entitled to receive stock, securities
or assets with respect to or in exchange for Common Stock, then, at the election
of each Warrantholder, in lieu of receiving such stock, securities or assets,
such Warrantholder shall receive cash equal to the Fair Value of the Common
Stock issuable upon exercise of the Warrant, less the Exercise Price payable
upon exercise thereof.

               In case any Additional Shares of Common Stock or Convertible
Securities or any rights or options to purchase any Additional Shares of Common
Stock or Convertible Securities shall be issued in connection with any merger of
another corporation into the Company, except for any acquisitions made by the
Company with the proceeds of the loan from the Bank, as set forth in the Loan
Agreement, of management service organizations which manage medical practices,
the amount of consideration therefor shall be deemed to be the Fair Value of
such portion of the assets of such merged corporation as the Board of Directors
of the Company shall in good faith determine to be attributable to such
Additional Shares of Common Stock, Convertible Securities or rights or options,
as the case may be, and the Exercise Price shall be adjusted in accordance with
this Section 6(d).

          (e)  COMPANY TO PREVENT DILUTION.  In case at any time or from time to
time conditions arise by reason of action taken by the Company which are not
adequately covered by the provisions of this Section 6, and which might
materially and adversely affect


                                          11
<PAGE>

the exercise rights of the Warrantholders under any provision of this Warrant,
unless the adjustment necessary shall be agreed upon by the Company and the
Warrantholders, the Board of Directors of the Company shall appoint a firm of
independent certified public accountants of recognized national standing (who
have not been employed by the Company within the last five years), acceptable to
the Warrantholders, who at the Company's expense shall give their opinion upon
the adjustment, if any, on a basis consistent with the standards established in
the other provisions of this Section 6, necessary with respect to the Exercise
Price and the number of shares purchasable upon exercise of the Warrants, so as
to preserve, without dilution, the exercise rights of the Warrantholders.  Upon
receipt of such opinion, such Board of Directors shall forthwith make the
adjustments described therein.

          (f)  STOCK SPLITS AND REVERSE SPLITS.  In case at any time the Company
shall subdivide its outstanding shares of Common Stock into a greater number of
shares, the Exercise Price in effect immediately prior to such subdivision shall
be proportionately reduced and the number of shares of Common Stock purchasable
pursuant to this Warrant immediately prior to such subdivision shall be
proportionately increased, and conversely, in case at any time the Company shall
combine its outstanding shares of Common Stock into a smaller number of shares,
the Exercise Price in effect immediately prior to such combination shall be
proportionately increased and the number of shares of Common Stock purchasable
upon the exercise of this Warrant immediately prior to such combination shall be
proportionately reduced.

          (g)  DISSOLUTION, LIQUIDATION AND WINDING-UP.  In case the Company
shall, at any time prior to the expiration of this Warrant, dissolve, liquidate
or wind up its affairs, the Warrantholders shall be entitled, upon the exercise
of this Warrant, to receive, in lieu of the shares of Common Stock of the
Company which such Warrantholders would have been entitled to receive, the same
kind and amount of assets as would have been issued, distributed or paid to such
Warrantholders upon any such dissolution, liquidation or winding up with respect
to such shares of Common Stock of the Company, had such Warrantholders been the
holders of record of the Warrant Shares receivable upon the exercise of this
Warrant on the record date for the determination of those persons entitled to
receive any such liquidating distribution.  After any such dissolution,
liquidation or winding up which shall result in any cash distribution in excess
of the Exercise Price provided for by this Warrant, the Warrantholders may, at
each such Warrantholder's option, exercise the same without making payment of
the Exercise Price, and in such case the Company shall, upon the distribution to
said Warrantholders, consider that said Exercise Price has been paid in full to
it and in making settlement to said Warrantholders, shall deduct from the amount
payable to such Warrantholders an amount equal to such Exercise Price.

          (h)  NONCASH CONSIDERATION.  In case any Additional Shares of Common
Stock or Convertible Securities or any rights or options to purchase any
Additional Shares of Common Stock or Convertible Securities shall be issued for
a consideration in a form other than cash, the amount of such consideration
shall be deemed to be the Fair Value thereof.


                                          12
<PAGE>

          (i)  ACCOUNTANTS' CERTIFICATE.  In each case of an adjustment in the
number of shares of Common Stock or other stock, securities or property
receivable on the exercise of the Warrants, the Company at its expense shall
cause independent public accountants of recognized standing selected by the
Company and acceptable to the Warrantholders to compute such adjustment in
accordance with the terms of this Warrant and prepare a certificate setting
forth such adjustment and showing in detail the facts upon which such adjustment
is based, including a statement of (a) the consideration received or to be
received by the Company for any Additional Shares of Common Stock, rights,
options or Convertible Securities issued or sold or deemed to have been issued
or sold, (b) the number of shares of Common Stock of each class outstanding or
deemed to be outstanding, (c) the adjusted Exercise Price and (d) the number of
shares issuable upon exercise of this Warrant.  The Company will forthwith mail
a copy of each such certificate to each Warrantholder.

          (j)  Notwithstanding anything contained herein to the contrary, if the
Company shall issue or sell Additional Shares of Common Stock or Convertible
Securities (whether for consideration per share less or in excess of the
Exercise Price in effect prior to such issuance) in connection with the
acquisition of assets, stock or management rights by the Company or any of its
subsidiaries or affiliates of Prime Care Medical Group of Antelope Valley, Inc.,
also known as Antelope Valley Medical Group (or of any other entity if such
acquisition occurs after the date hereof but on or before June 1, 1998), the
Warrantholders shall thereafter be entitled to purchase at the Exercise Price an
additional number of shares of Common Stock equal to the product of (i) 1%
times, (ii) the number of shares of Common Stock issued or number of shares of
Common Stock issuable upon conversion or exercise of the Convertible Securities,
whichever is the case ("Acquisition Adjustment"); provided, however, that if
without giving effect to this Section 6(j), the number of shares resulting from
the adjustment provided by Section 6(a), 6(b), 6(c) and/or 6(d) would exceed the
Acquisition Adjustment, then the result obtained by application of Section 6(a),
6(b), 6(c) and/or 6(d) shall supersede the Acquisition Adjustment amount.

     7.   SPECIAL AGREEMENTS OF THE COMPANY.

          (a)  RESERVATION OF SHARES.  The Company covenants and agrees that all
Warrant Shares will, upon issuance, be validly issued, fully paid and
nonassessable and free from all preemptive rights of any stockholder, and from
all taxes, liens and charges with respect to the issue thereof.  The Company
further covenants and agrees that during the period within which the rights
represented by this Warrant may be exercised, the Company will at all times have
authorized, and reserved, a sufficient number of shares of Common Stock to
provide for the exercise of the rights represented by this Warrant.  The Company
hereby covenants and agrees to take all such action as may be necessary to
assure that the par value per share of the Common Stock is at all times equal to
or less than the Exercise Price.

          (b)  AVOIDANCE OF CERTAIN ACTIONS.  The Company will not, by amendment
of its Articles or Certificate of Incorporation or through any reorganization,
transfer of assets, consolidation, merger, issue or sale of securities or
otherwise, avoid or take any


                                          13
<PAGE>

action which would have the effect of avoiding the observance or performance of
any of the terms to be observed or performed hereunder by the Company, but will
at all times in good faith assist in carrying out all of the provisions of this
Warrant and in taking all of such action as may be necessary or appropriate in
order to protect the rights of the Warrantholders against dilution or other
impairment of their rights hereunder.

          (c)  SECURING GOVERNMENTAL APPROVALS.  If any shares of Common Stock
required to be reserved for the purposes of exercise of this Warrant require
registration with or approval of any governmental authority under any federal
law (other than the Securities Act) or under any state law before such shares
may be issued upon exercise of this Warrant, the Company will, at its expense,
as expeditiously as possible, cause such shares to be duly registered or
approved, as the case may be.

          (d)  LISTING ON SECURITIES EXCHANGES; REGISTRATION.  If, and so long
as, any class of the Company's Common Stock shall be listed on any national
securities exchange (as defined in the Exchange Act), the Company will, at its
expense, obtain and maintain the approval for listing upon official notice of
issuance of all Warrant Shares and maintain the listing of Warrant Shares after
their issuance; and the Company will so list on such national securities
exchange, will register under the Exchange Act (or any similar statute then in
effect), and will maintain such listing of, any other securities that at any
time are issuable upon exercise of this Warrant if and at the time any
securities of the same class shall be listed on such national securities
exchange by the Company.

          (e)  INFORMATION RIGHTS.  So long as the Warrantholders hold this
Warrant and/or any of the Warrant Shares, the Company shall deliver to the
Warrantholders (i) promptly after mailing, copies of all communications to the
shareholders of the Company, (ii) within ninety (90) days after the end of each
fiscal year of the Company, the annual audited financial statements of the
Company certified by the independent public accountants of recognized standing,
and (iii) within forty-five (45) days after the end of each of the first three
quarters of each fiscal year, the Company's quarterly, unaudited financial
statements.

          (f)  RESTRICTIONS ON PUBLIC SALE BY THE COMPANY.  The Company will not
effect any public or private sale or distribution of its convertible debt or
equity securities, including a sale pursuant to Regulation D under the
Securities Act, during the Protected Period of each underwritten offering by the
Company made pursuant to a registration statement filed pursuant to
Sections 11(a) or 11(b).  In addition, the Company shall cause each holder of
its privately placed convertible debt or equity securities issued by it at any
time on or after the date of this Warrant to agree not to effect any public sale
or distribution of any such securities during such Period, including a sale
pursuant to Rule 144 or Rule 144A under the Securities Act; provided, however,
that no such agreement shall be required with respect to any such debt or equity
securities which are to be issued by the Company in a transaction which is
intended to be treated as a pooling of interests if the existence of such
agreement would cause the transaction to fail to qualify for such treatment.


                                          14
<PAGE>

          (g)  PREEMPTIVE RIGHTS.  In the event the Company offers to the
Company's shareholders the right to purchase any securities of the Company, then
all shares of Common Stock issuable pursuant to the Warrants shall be deemed to
be issued and outstanding and held by the Warrantholders and the Warrantholders
shall be entitled to participate in such rights offering.

          (h)  COMPLIANCE WITH LAW.  The Company shall comply with all
applicable laws, rules and regulations of the United States and of all states,
municipalities and agencies and of any other jurisdiction applicable to the
Company and shall do all things necessary to preserve, renew and keep in full
force and effect and in good standing its corporate existence and authority
necessary to continue its business.

     8.   FRACTIONAL SHARES.  No fractional shares or scrip representing
fractional shares shall be issued upon the exercise of this Warrant.  With
respect to any fraction of a share called for upon exercise hereof, the Company
shall pay to the Warrantholder an amount in cash equal to such fraction
multiplied by the Current Market Value of one share of Common Stock.

     9.   NOTICES OF STOCK DIVIDENDS, SUBSCRIPTIONS, RECLASSIFICATIONS,
CONSOLIDATIONS, MERGERS, ETC.  If at any time:  (i) the Company shall declare a
cash dividend (or an increase in the then existing dividend rate), or declare a
dividend on Common Stock payable otherwise than in cash out of its net earnings
after taxes for the prior fiscal year; or (ii) the Company shall authorize the
granting to the holders of Common Stock of rights to subscribe for or purchase
any shares of capital stock of any class or of any other rights; or (iii) there
shall be any capital reorganization, or reclassification, or redemption of the
capital stock of the Company, or consolidation or merger of the Company with, or
sale of all or substantially all of its assets to, another corporation or firm;
or (iv) there shall be a voluntary or involuntary dissolution, liquidation or
winding up of the Company, then the Company shall give to the Warrantholders at
the addresses of such Warrantholders as shown on the books of the Company, at
least twenty (20) days prior to the applicable record date hereinafter

selected, the date as of which the holders of Common Stock of record entitled to
such dividend or rights are to be determined), the date on which any such
reorganization, reclassification, consolidation, merger, sale of assets,
dissolution, liquidation or winding up is expected to become effective, and the
date as of which it is expected the holders of Common Stock of record shall be
entitled to effect any exchange of their shares of Common Stock for cash (or
cash equivalent), securities or other property deliverable upon any such
reorganization, reclassification, consolidation, merger, sale of assets,
dissolution, liquidation or winding up.

     10.  REGISTERED HOLDER; TRANSFER OF WARRANTS OR WARRANT SHARES.

          (a)  MAINTENANCE OF REGISTRATION BOOKS; OWNERSHIP OF THIS WARRANT.
The Company shall keep at its principal office a register in which the Company
shall provide for the registration, transfer and exchange of this Warrant.  The
Company shall not at any time,


                                          15
<PAGE>

except upon the dissolution, liquidation or winding-up of the Company, close
such register so as to result in preventing or delaying the exercise or transfer
of this Warrant.

          (b)  EXCHANGE AND REPLACEMENT.  This Warrant is exchangeable upon
surrender hereof by the registered holder to the Company at its principal office
for new Warrants of like tenor and date representing in the aggregate the right
to purchase the number of shares purchasable hereunder, each of such new
Warrants to represent the right to purchase such number of shares as shall be
designated by said registered holder at the time of surrender.  Subject to
compliance with all restrictions and provisions of this Warrant, this Warrant
and all rights hereunder are transferable in whole or in part upon the books of
the Company by the registered holder hereof in person or by duly authorized
attorney, and new Warrants shall be made and delivered by the Company, of the
same tenor and date as this Warrant but registered in the name of the
transferee(s), upon surrender of this Warrant, duly endorsed, to said office of
the Company.  Upon receipt by the Company of evidence reasonably satisfactory to
it of the loss, theft, destruction or mutilation of this Warrant, and upon
surrender and cancellation of this Warrant, if mutilated, the Company will make
and deliver a new Warrant of like tenor, in lieu of this Warrant, without
requiring the posting of any bond or the giving of any other security.  This
Warrant shall be promptly cancelled by the Company upon the surrender hereof in
connection with any exchange, transfer or replacement.  The Company shall pay
all expenses, taxes and other charges payable in connection with the
preparation, execution and delivery of Warrants pursuant to this Section 10.

          (c)  WARRANTS AND WARRANT SHARES NOT REGISTERED.  The holder of this
Warrant, by accepting this Warrant, represents and acknowledges that this
Warrant and the Warrant Shares are not being registered under the Securities Act
on the grounds that the issuance of this Warrant and the offering and sale of
such Warrant Shares are exempt from registration under Section 4(2) of the
Securities Act as not involving any public offering.

     11.  REGISTRATION.

          (a)  REQUIRED REGISTRATION.  After three (3) years from the date of
this Warrant, whenever the Company shall receive a written request therefor from
any holder or holders of at least 10% of the Registrable Stock, the Company
shall promptly prepare and file a registration statement under the Securities
Act covering the Registrable Stock which is the subject of such request and
shall use its best efforts to cause such registration statement to become
effective as expeditiously as possible.  Upon the receipt of such request, the
Company shall promptly give written notice to all holders of Registrable Stock
that such registration is to be effected.  The Company shall include in such
registration statement such Registrable Stock for which it has received written
requests to register such shares by the holders thereof within thirty (30) days
after the effectiveness of the Company's written notice to such other holders.
The Registrable Stock owned by the Bank under this Warrant shall receive
priority over all other shares of stock included in a registration statement
under this Section 11(a).  Notwithstanding the above, the Company is obligated
to effect only one (1) registration pursuant to this Section 11(a).


                                          16
<PAGE>

          (b)  INCIDENTAL REGISTRATION.  Each time the Company shall determine
to file a registration statement under the Securities Act (other than on
Form S-8 or Form S-4) in connection with the proposed offer and sale for money
of any of its securities by it or by any of its security holders, the Company
will give written notice of its determination to all holders of Registrable
Stock.  Upon the written request of a holder of any Registrable Stock, the
Company will cause all such Registrable Stock, the holders of which have so
requested registration thereof, to be included in such registration statement,
all to the extent requisite to permit the sale or other disposition by the
prospective seller or sellers of the Registrable Stock to be so registered in
accordance with the terms of the proposed offering.  If the registration
statement is to cover an underwritten distribution, the Company shall use its
best efforts to cause the Registrable Stock requested for inclusion pursuant to
this Section 11(b) to be included in the underwriting on the same terms and
conditions as the securities otherwise being sold through the underwriters.  If,
in the good faith judgment of the managing underwriter of such public offering,
the inclusion of all of the Registrable Stock requested to be registered would
materially and adversely affect the successful marketing of the other shares
proposed to be offered, then the amount of the Registrable Stock to be included
in the offering shall be reduced and the Registrable Stock and the other shares
to be offered shall participate in such offering as follows:  the shares to be
sold by the Company, the Registrable Stock to be included in such offering and
the other shares of Common Stock to be included in such offering shall each be
reduced pro rata in proportion to the number of shares of Common Stock proposed
to be included in such offering by each holder of such shares and by the
Company.

          (c)  REGISTRATION PROCEDURES.  If and whenever the Company is required
by the provisions of Section 11(a) or 11(b) to effect the registration of
Registrable Stock under the Securities Act, the Company will, at its expense, as
expeditiously as possible:

               (i)    In accordance with the Securities Act and the rules and
regulations of the Commission, prepare and file with the Commission a
registration statement on the form of registration statement appropriate with
respect to such securities and use its best efforts to cause such registration
statement to become and remain effective until the earlier of (x) the date on
which the securities covered by such registration statement have been sold, or
(y) one hundred eighty (180) days after the effective date thereof, and prepare
and file with the Commission such amendments to such registration statement and
supplements to the prospectus contained therein as may be necessary to keep such
registration statement effective and such registration statement and prospectus
accurate and complete until the securities covered by such registration
statement have been sold;

               (ii)   If the offering is to be underwritten, in whole or in
part, enter into a written underwriting agreement with the holders of the
Registrable Stock participating in such offering and the underwriter in form and
substance reasonably satisfactory to the managing underwriter of the public
offering and the holders of the Registrable Stock participating in such
offering;


                                          17
<PAGE>

               (iii)  Furnish to the holders of securities participating in
such registration and to the underwriters of the securities being registered
such reasonable number of copies of the registration statement, preliminary
prospectus, final prospectus and such other documents as such underwriters and
holders may reasonably request in order to facilitate the public offering of
such securities;

               (iv)   Use its best efforts to register or qualify the
securities covered by such registration statement under such state securities or
blue sky laws of such jurisdictions as such participating holders and
underwriters may reasonably request;

               (v)    Notify the holders participating in such registration,
promptly after it shall receive notice thereof, of the date and time when such
registration statement and each post-effective amendment thereto has become
effective or a supplement to any prospectus forming a part of such registration
statement has been filed;

               (vi)   Notify such holders promptly of any request by the
Commission for the amending or supplementing of such registration statement or
prospectus or for additional information;

               (vii)  Prepare and file with the Commission, promptly upon the
request of any such holders, any amendments or supplements to such registration
statement or prospectus which, in the opinion of counsel for such holders, is
required under the Securities Act or the rules and regulations thereunder in
connection with the distribution of the Registrable Stock by such holders;

               (viii) Prepare and promptly file with the Commission, and
promptly notify such holders of the filing of, such amendments or supplements to
such registration statement or prospectus as may be necessary to correct any
statements or omissions if, at the time when a prospectus relating to such
securities is required to be delivered under the Securities Act, any event has
occurred as the result of which any such prospectus or any other prospectus as
then in effect may include an untrue statement of a material fact or omit to
state any material fact required to be stated therein or necessary to make the
statements therein not misleading;

               (ix)   In case any of such holders or any underwriter for any
such holders is required to deliver a prospectus at a time when the prospectus
then in circulation is not in compliance with the Securities Act or the rules
and regulations of the Commission, prepare promptly upon request such amendments
or supplements to such registration statement and such prospectus as may be
necessary in order for such prospectus to comply with the requirements of the
Securities Act and such rules and regulations;

               (x)    Advise such holders, promptly after it shall receive
notice or obtain knowledge thereof, of the issuance of any stop order by the
Commission suspending the effectiveness of such registration statement or the
initiation or threatening of any


                                          18
<PAGE>

proceeding for that purpose and promptly use its best efforts to prevent the
issuance of any stop order or to obtain its withdrawal if such stop order should
be issued;

               (xi)   If requested by the managing underwriter or underwriters
or a holder of Registrable Stock being sold in connection with an underwritten
offering, immediately incorporate in a prospectus supplement or post-effective
amendment such information as the managing underwriters and the holders of a
majority of the Registrable Stock being sold agree should be included therein
relating to the plan of distribution with respect to such Registrable Stock,
including information with respect to the Registrable Stock being sold to such
underwriters, the purchase price being paid therefor by such underwriters and
with respect to any other terms of the underwritten (or best efforts
underwritten) offering of the Registrable Stock to be sold in such offering; and
make all required filings of such prospectus supplement or post-effective
amendment as soon as notified of the matters to be incorporated in such
prospectus supplement or post-effective amendment;

               (xii)  Cooperate with the selling holders of Registrable Stock
and the managing underwriters, if any, to facilitate the timely preparation and
delivery of certificates representing Registrable Stock to be sold and not
bearing any restrictive legends; and enable such Registrable Stock to be in such
denominations and registered in such names as the managing underwriters may
request at least two business days prior to any sale of Registrable Stock to the
underwriters;

               (xiii) Prepare a prospectus supplement or post-effective
amendment to the registration statement or the related prospectus or any
document incorporated therein by reference or file any other required documents
so that, as thereafter delivered to the purchasers of the Registrable Stock, the
prospectus will not contain an untrue statement of material fact or omit to
state any material fact necessary to make the statements therein not misleading;

               (xiv)  Enter into such agreements (including an underwriting
agreement) and take all such other actions in connection therewith in order to
expedite or facilitate the disposition of such Registrable Stock and in such
connection, whether or not an underwriting agreement is entered into and whether
or not the registration is an underwritten registration:

                      (A)     make such representations and warranties to the
holders of such Registrable Stock and the underwriters, if any, in form,
substance and scope as are customarily made by issuers to underwriters in
primary underwritten offerings;

                      (B)     If an underwriting agreement is entered into, the
same shall set forth in full the indemnification provisions and procedures of
Section 11(e) hereof with respect to all parties to be indemnified pursuant to
said Section; and

                      (C)     The Company shall deliver such documents and
certificates as may be requested by the holders of the majority of the
Registrable Stock being


                                          19
<PAGE>

sold and the managing underwriters, if any, to evidence compliance with the
terms of this Section 11(c) and with any customary conditions contained in the
underwriting agreement or other agreement entered into by the Company.

                      The above shall be done at each closing under such
underwriting or similar agreement or as and to the extent required thereunder;

               (xv)   Make available for inspection by a representative of the
holders of a majority of the Registrable Stock, any underwriter participating in
any disposition pursuant to a registration statement, and any attorney or
accountant retained by the sellers or underwriter, all financial and other
records, pertinent corporate documents and properties of the Company, and cause
the Company's officers, directors and employees to supply all information
reasonably requested by any such representative, underwriter, attorney or
accountant in connection with the preparation of the registration statement;
provided, that any records, information or documents that are designated by the
Company in writing as confidential shall be kept confidential by such persons
unless disclosure of such records, information or documents is required by court
or administrative order;

               (xvi)  Otherwise use its best efforts to comply with all
applicable rules and regulations of the Commission, and make generally available
to the Company's security holders, earning statements satisfying the provisions
of Section 11(a) of the Securities Act, no later than forty-five (45) days after
the end of any twelve (12) month period (or ninety (90) days, if such a period
is a fiscal year) (i) commencing at the end of any fiscal quarter in which
Registrable Stock is sold to underwriters in an underwritten offering, or, if
not sold to underwriters in such an offering, (ii) beginning with the first
month of the Company's first fiscal quarter commencing after the effective date
of a registration statement;

               (xvii) Not file any amendment or supplement to such registration
statement or prospectus to which a majority in interest of such holders has
objected on the grounds that such amendment or supplement does not comply in all
material respects with the requirements of the Securities Act or the rules and
regulations thereunder, after having been furnished with a copy thereof at least
five (5) business days prior to the filing thereof; provided, however, that the
failure of such holders or their counsel to review or object to any amendment or
supplement to such registration statement or prospectus shall not affect the
rights of such holders or any controlling person or persons thereof or any
underwriter or underwriters therefor under Section 11(e) hereof; and

               (xviii)At the request of any such holder (i) furnish to
such holder on the effective date of the registration statement or, if such
registration includes an underwritten public offering, at the closing provided
for in the underwriting agreement, an opinion, dated such date, of the counsel
representing the Company for the purposes of such registration, addressed to the
underwriters, if any, and to the holder or holders making such request, covering
such matters with respect to the registration statement, the prospectus and each
amendment or supplement thereto, proceedings under state and federal securities
laws, other matters relating to the Company, the securities being registered and
the offer and sale


                                          20
<PAGE>

of such securities as are customarily the subject of opinions of issuer's
counsel provided to underwriters in underwritten public offerings, and such
opinion of counsel shall additionally cover such legal and factual matters with
respect to the registration as such requesting holder or holders may reasonably
request, and (ii) use its best efforts to furnish to such holder letters dated
each such effective date and such closing date, from the independent certified
public accountants of the Company, addressed to the underwriters, if any, and to
the holder or holders making such request, stating that they are independent
certified public accountants within the meaning of the Securities Act and
dealing with such matters as the underwriters may request, or, if the offering
is not underwritten, that in the opinion of such accountants the financial
statements and other financial data of the Company included in the registration
statement or the prospectus or any amendment or supplement thereto comply in all
material respects with the applicable accounting requirements of the Securities
Act, and additionally covering such other financial matters, including
information as to the period ending immediately prior to the date of such letter
with respect to the registration statement and prospectus, as such requesting
holder or holders may reasonably request.

          (d)  EXPENSES OF REGISTRATION.  All expenses incident to the Company's
performance of or compliance with this Warrant, including, without limitation,
the following shall be borne by the Company, regardless of whether the

          (e)  INDEMNIFICATION.

               (i)    The Company hereby agrees to indemnify each of the
holders of Registrable Stock against all claims, losses, damages and liabilities
(or actions in respect thereof) arising out of or based on any untrue statement
(or alleged untrue statement) of a material fact contained in any registration
statement, preliminary or final prospectus, or other document incident to any
such registration, qualification or compliance (or in any related registration
statement, notification or the like) or any omission (or alleged omission) to
state therein a material fact required to be stated therein or necessary to make
the statements therein not misleading, or any violation by the Company of any
rule or regulation promulgated under the Securities Act applicable to the
Company and relating to action or inaction required of the Company in connection
with any such registration, qualification or compliance, and to reimburse the
holders of Registrable Stock (including officers and directors of the same and
controlling persons) for any legal and any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action, PROVIDED, HOWEVER, that the Company will not be liable in
any such case to the extent that any such claim, loss, damage or liability
arises out of or is based on any untrue statement or omission based upon written
information furnished to the Company by Warrantholders in an instrument duly
executed by Warrantholders and stated to be specifically for use therein.

               (ii)   The Warrantholders severally and not jointly agree to
indemnify the Company and its officers and directors and each person, if any,
who controls any thereof within the meaning of Section 15 of the Securities Act
and their respective successors against all claims, losses, damages and
liabilities (or actions in respect thereof) arising out of or based on any
untrue statement of a material fact contained in any prospectus, offering
circular or other document incident to any registration, qualification or
compliance relating to securities purchased pursuant to the Warrants (or in any
related registration statement, notification or the like) or any omission (or
alleged omission) to state therein a material fact required to be stated therein
or necessary to make the statements therein not misleading and


                                          22
<PAGE>

will reimburse the Company and each other person indemnified pursuant to this
subsection (ii) for any legal and any other expenses reasonably incurred in
connection with investigating or defending any such claim, loss, damage,
liability or action; PROVIDED, HOWEVER, that this subsection (ii) shall apply
only if (and only to the extent that) such statement or omission was made in
reliance upon information (including, without limitation, written negative
responses to inquiries) furnished to the Company by an instrument duly executed
by Warrantholders and stated to be specifically for use in such prospectus, or
other document (or related registration statement, notification or the like) or
any amendment or supplement thereto.

               (iii)  Each party entitled to indemnification hereunder (the
"Indemnified Party") shall give notice to the party required to provide
indemnification (the "Indemnifying Party") promptly after such Indemnified Party
has actual knowledge of any claim as to which indemnity may be sought, and shall
permit the Indemnifying Party (at such Indemnifying Party's expense) to assume
the defense of any claim or any litigation resulting therefrom, provided that
counsel for the Indemnifying Party, who shall conduct the defense of such claim
or litigation, shall be satisfactory to the Indemnified Party, and the
Indemnified Party may participate in such defense at such party's expense, and
provided, further, that the omission by any Indemnified Party to give notice as
provided herein shall not relieve the Indemnifying Party of its obligations
under this Section 11(e) except to the extent that the omission results in a
failure of actual notice to the Indemnifying Party and such Indemnifying Party
is materially damaged solely as a result of the failure to give notice.  No
Indemnifying Party, in the defense of any such claim or litigation, shall,
except with the consent of each Indemnified Party, consent to entry of any
judgment or enter into any settlement which does not include as an unconditional
term thereof the giving by the claimant or plaintiff to such Indemnified Party
of a release from all liability in respect to such claim or litigation.

               (iv)   If the indemnification provided for in this Section 11(e)
is unavailable or insufficient to hold harmless an Indemnified Party in respect
of any losses, claims, damages, liabilities, expenses or actions in respect
thereof referred to herein, then the Indemnifying Party shall contribute to the
amount paid or payable by such Indemnified Party as a result of such losses,
claims, damages, liabilities, expenses or actions in such proportion as is
appropriate to reflect the relative fault of the Indemnifying Party on the one
hand, and the Indemnified Party on the other, in connection with the statements
or omissions which resulted in such losses, claims, damages, liabilities,
expenses or actions as well as any other relevant equitable considerations,
including the failure to give the notice required hereunder.  The relative fault
of the Indemnifying Party and the Indemnified Party shall be determined by
reference to, among other things, whether the untrue or alleged untrue statement
of a material fact relates to information supplied by the Indemnifying Party or
the Indemnified Party and the parties' relative intent, knowledge, access to
information and opportunity to correct or prevent such statement or omission.
The Company and the Warrantholders  agree that it would not be just and
equitable if contributions pursuant to this Section 11(e) were determined by pro
rata allocation or by any other method of allocation which did not take account
of the equitable considerations referred to above.  The amount


                                          23
<PAGE>

paid or payable to an Indemnified Party as a result of the losses, claims,
damages, liabilities or actions in respect thereof, referred to above, shall be
deemed to include any legal or other expenses reasonably incurred by such
Indemnified Party in connection with investigating or defending any such action
or claim.  Notwithstanding the contribution provisions of this Section 11(e), in
no event shall the amount contributed by any seller of Registrable Stock exceed
the aggregate net offering proceeds received by such seller from the sale of
Registrable Stock to which such contribution or indemnification claim relates.
No person guilty of fraudulent misrepresentations (within the meaning of
Section 11(f) of the Securities Act) shall be entitled to contribution from any
person who is not guilty of such fraudulent misrepresentation.

               (v)    The indemnification required by this Section 11(e) shall
be made by periodic payments during the course of the investigation or defense,
as and when bills are received or expenses incurred.  Anything contained herein
to the contrary notwithstanding, the maximum aggregate liability of any holder
of Registrable Stock under this Section 11(e) shall not exceed the amount of the
net proceeds actually received by such holder from the sale of its Registrable
Stock pursuant to the registration, qualification, notification or compliance in
respect of which such liability arose.

          (f)  REPORTING REQUIREMENTS UNDER EXCHANGE ACT.  From and after the
effective date of the first registration statement filed by the Company under
the Securities Act, the Company shall (whether or not it shall then be required
to do so) timely file such information, documents and reports as the Commission
may require or prescribe under Section 13 or 15(d) (whichever is applicable) of
the Exchange Act.  Immediately upon becoming subject to the reporting
requirements of either Section 13 or 15(d) of the Exchange Act, the Company
shall forthwith upon request furnish any holder of Registrable Stock (i) a
written statement by the Company that it has complied with such reporting
requirements, (ii) a copy of the most recent annual or quarterly report of the
Company, and (iii) such other reports and documents filed by the Company with
the Commission as such holder may reasonably request in availing itself of an
exemption for the sale of Registrable Stock without registration under the
Securities Act.  The Company acknowledges and agrees that the purpose of the
requirements contained in this Section 11(f) is to enable any such holder to
comply with the current public information requirement contained in Rule 144
under the Securities Act should such holder ever wish to dispose of any of the
securities of the Company acquired by it without registration under the
Securities Act in reliance upon Rule 144 (or any other similar exemptive
provision).  In addition, the Company shall take such other measures and file
such other information, documents and reports as shall hereafter be required by
the Commission as a condition to the availability of Rule 144 and Rule 144A
under the Securities Act (or any similar exemptive provision hereafter in
effect).

          (g)  STOCKHOLDER INFORMATION.  The Company may require each holder of
Registrable Stock as to which any registration is to be effected pursuant to
this Section 11 to furnish the Company such information with respect to such
holder and the distribution of such Registrable Stock as shall be required by
law or by the Commission in connection therewith.


                                          24

          (h)  TERMINATION OF REQUIREMENTS TO REGISTER.  The obligations of the
Company under Sections 11(a) and 11(b) hereof shall terminate when all of the
Registrable Stock may be sold by all holders without restriction under the
Securities Act.

     12.  REPRESENTATION AND WARRANTIES.  The Company hereby represents and
warrants to and covenants with the Bank, each Warrantholder, and each holder of
Warrant Shares that:

          (a)  ORGANIZATION AND CAPITALIZATION OF THE COMPANY.  The Company is a
corporation duly organized, validly existing and in good standing under the laws
of the State of Delaware.  As of the date hereof, the authorized capital of the
Company consists of forty million (40,000,000) shares of Common Stock and one
million (1,000,000) shares of Preferred Stock, of which five million three

and the execution, delivery and performance hereof has been duly authorized by
all necessary corporate action on its part.  This Warrant has been duly executed
on behalf of the Company and constitutes the legal, valid and binding obligation
of the Company enforceable in accordance with its terms.

          (c)  NO LEGAL BAR.  Neither the execution, delivery or performance of
this Warrant nor the issuance of the shares of Common Stock issuable upon
exercise of this Warrant will (a) conflict with or result in a violation of the

result in a violation of any law, statute, regulation, order or decree
applicable to the Company or any affiliate, (c) require any consent or

continue to be entitled to all rights to which a Warrantholder is entitled
pursuant to the provisions of this Warrant except such rights as by their terms
apply solely to a Warrantholder, notwithstanding the fact that this Warrant has
been exercised or the period of exercisability has expired.  The Company will,
at any time upon the request of the Bank or a holder of the Warrant Shares,
acknowledge in writing, in form reasonably satisfactory to the Bank or such
holder, the Company's continuing obligation to afford to the Bank or such holder
all rights to which the Bank or such holder shall continue to be entitled in
accordance with the provisions of this Warrant; PROVIDED, HOWEVER, that if the
Bank or such holder shall fail to make any such request, such failure shall not
affect the continuing obligation of the Company to afford to the Bank and such
holder all such rights.

     14.  MISCELLANEOUS PROVISIONS.

          (a)  NOTICE OF EXPIRATION.  The Company shall give written notice to
the Warrantholders specifically advising them of the Expiration Date and of
their right to exercise the Warrants not more than one hundred eighty (180) days
and not less than ninety (90) days before the Expiration Date.  If such written
notice is not so given, the Expiration Date shall automatically be extended
until ninety (90) days after the date that the Company gives the Warrantholders
such written notice.

          (b)  JUDICIAL REFERENCE.

               (i)    Other than the appointment of a receiver, or the exercise
of other provisional remedies (any and all of which may be initiated pursuant to
applicable law), each controversy, dispute or claim arising out of or relating
to this Warrant, which controversy, dispute or claim is not settled in writing
within thirty (30) days after the "CLAIM DATE" (defined as the date on which the
Company or a Warrantholder gives written notice to the other that a controversy,
dispute or claim exists), will be settled by a reference proceeding in
California in accordance with the provisions of Section 638 et seq. of the
California Code of Civil Procedure, or their successor section ("CCP"), which
shall constitute the exclusive remedy for the settlement of any controversy,
dispute or claim concerning this Warrant, including whether such controversy,
dispute or claim is subject to the reference proceeding and except as set forth
above, the parties waive their rights to initiate any legal proceedings against
each other in any court or jurisdiction other than the


                                          26
<PAGE>

Superior Court in counties of Los Angeles or Orange, California (the "COURT").
The referee shall be a retired Judge of the Court selected by mutual agreement
of the parties, and if they cannot so agree within forty-five (45) days after
the Claim Date, the referee shall be promptly selected by the Presiding Judge of
the Court (or his or her representative).  The referee shall be appointed to sit
as a temporary judge, with all of the powers for a temporary judge, as
authorized by law, and upon selection should take and subscribe to the oath of
office as provided for in Rule 244 of the California Rules of Court (or any
subsequently enacted Rule).  Each party shall have one peremptory challenge
pursuant to CCP Section 170.6.  The referee shall (i) be requested to set the
matter for hearing within sixty (60) days after the Claim Date and (ii) try any
and all issues of law or fact and report a statement of decision upon them, if
possible, within ninety (90) days of the Claim Date.  Any decision rendered by
the referee will be final, binding and conclusive and judgment shall be entered
pursuant to CCP Section 644 in any court in the State of California having
jurisdiction.  Any party may apply for a reference proceeding at any time after
thirty (30) days following notice to any other party of the nature of the
controversy, dispute or claim, by filing a petition for a hearing and/or trial.
All discovery permitted by this Warrant shall be completed no later than fifteen
(15) days before the first hearing date established by the referee.  The referee
may extend such period in the event of a party's refusal to provide requested
discovery for any reason whatsoever, including, without limitation, legal
objections raised to such discovery or unavailability of a witness due to
absence or illness.  No party shall be entitled to "priority" in conducting
discovery.  Depositions may be taken by either party upon seven (7) days written
notice, and request for production or inspection of documents shall be responded
to within ten (10) days after service.  All disputes relating to discovery which
cannot be resolved by the parties shall be submitted to the referee whose
decision shall be final and binding upon the parties.  Pending appointment of
the referee as provided herein, the Court is empowered to issue temporary and/or
provisional remedies, as appropriate.

               (ii)   Except as expressly set forth in this Warrant, the
referee shall determine the manner in which the reference proceeding is
conducted including the time and place of all hearings, the order of
presentation of evidence, and all other questions that arise with respect to the
course of the reference proceeding.  All proceedings and hearings conducted
before the referee, except for trial, shall be conducted without a court
reporter except that when any party so requests, a court reporter will be used
at any hearing conducted before the referee.  The party making such a request
shall have the obligation to arrange for and pay for the court reporter.  The
costs of the court reporter at the trial shall be borne equally by the parties.

               (iii)  The referee shall be required to determine all issues in
accordance with existing case law and the statutory laws of the State of
California.  The rules of evidence applicable to proceedings at law in the State
of California will be applicable to the reference proceeding.  The referee shall
be empowered to enter equitable as well as legal relief, to provide all
temporary and/or provisional remedies and to enter equitable orders that will be
binding upon the parties.  The referee shall issue a single judgment at the
close of the reference proceeding which shall dispose of all of the claims of
the parties that are the subject of the reference.  The parties hereto expressly
reserve the


                                          27
<PAGE>

right to contest or appeal from the final judgment or any appealable order or
appealable judgment entered by the referee.  The parties hereto expressly
reserve the right to findings of fact, conclusions of laws, a written statement
of decision, and the right to move for a new trial or a different judgment,
which new trial, if granted, is also to be a reference proceeding under this
provision.

               (iv)   In the event that the enabling legislation which provides
for appointment of a referee is repealed (and no successor statute is enacted),
any dispute between the parties that would otherwise be determined by the
reference procedure herein described will be resolved and determined by
arbitration.  The arbitration will be conducted by a retired judge of the Court,
in accordance with the California Arbitration Act, Section 1280 through Section
1294.2 of the CCP as amended from time to time.  The limitations with respect to
discovery as set forth hereinabove shall apply to any such arbitration
proceeding.

to patients of such entities.  Except for services rendered in Physician's

with Physician's performance of his or her obligations hereunder.

Practice employees generally.  Notwithstanding the foregoing, Physician shall be
entitled to maintain an internal medicine and gastroenterology practice located

not perform medical services for any capitated primary care patient outside the
consulting arrangement between Company and Sierra pursuant to this Agreement.

            Nothing herein shall be construed to prevent Physician from

services under any circumstances, including but not limited to the event of

receiving notice of any such surcharge or other prohibited payment by Physician,
shall take appropriate action to assist the affected enrollee in obtaining
restitution and to prevent a recurrence by, for example, terminating this
Agreement for material breach, which shall be deemed not to be subject to cure
unless otherwise determined by Sierra, in its sole discretion.  The term
"surcharge" shall have the meaning provided in regulations promulgated pursuant

immediate family; and

            (f)  A policy of vision insurance for Physician and Physician's
immediate family.

     However, with respect to the foregoing benefits, Sierra's life insurance
company, if any, and/or disability insurer, if any, may require Physician to
satisfactorily pass a physical examination in order to issue a life insurance
policy to Physician, and Physician shall comply with all such reasonable
requirements.  In addition, Sierra may elect to obtain key-man life insurance
coverage on Physician, and Physician agrees to submit to any required
examination therefor.

     2.3    VACATION BENEFITS.  Company shall be entitled to allow Physician
four weeks of paid vacation for each twelve month period ending on September 24,
commencing on the date hereof; provided, however, that for the twelve month

reduced by any such paid vacation taken by Physician under the Employment
Agreement.  Additionally, Company shall be entitled to allow Physician to take
up to one week per year for continuing medical education classes.

     2.4    MALPRACTICE INSURANCE. Sierra will purchase and maintain a
professional liability insurance policy for Physician on Company's behalf which

3.   TERM AND TERMINATION OF AGREEMENT

     3.1    CONTRACT TERM.  The initial term of this Agreement shall commence

                                      6

<PAGE>

     3.3    TERMINATION BY SIERRA.  Sierra may terminate this Agreement 
hereunder at any time for "cause" by giving notice of termination (the 
"Termination Notice") to the Company.  Cause includes the following:

            (a)  Upon material violation by Company or Physician of any
provisions of this Agreement or the rules, policies, and/or procedures of the

performance, or productivity standards established by Sierra for the Practice.

            (c)  Upon revocation, cancellation, suspension or limitation of

appropriate licensing authority including, without limitation, the revocation,
suspension, limitation, or reduction of such license or of Physician's DEA
license.

            (d)  Upon cancellation of Company's or Physician's coverage, or his
uninsurability, under the terms and conditions of the professional liability
insurance provided by Sierra as set forth above.

            (e)  Upon the imposition of any restrictions or limitations on
Company or Physician by any governmental or professional authority having
jurisdiction over Physician to such an extent that Company or Physician cannot
engage in the practice of medicine as required hereunder.

            (f)  Upon Company's or Physician's conviction of a felony or crime
of moral turpitude.

            (g)  Upon repeated failure by Company or Physician to conform and
comply with Sierra's professional requirements concerning maintenance of medical
records.

            (h)  Upon the use of alcohol or a controlled substance which

            (i)  If Sierra, in good faith, determines that Physician is not
providing adequate patient care or that the health, safety or welfare of
patients is jeopardized by continuing the consulting arrangement with the
Company for the services of Physician.

            (j)  In the event the performance by either party hereto of any
term, covenant, condition or provision of this Agreement should jeopardize (1)
the licensure of Sierra, any Affiliate of Sierra, or Physician, or (2) Sierra's
(or any Affiliate's) or Physician's participation in, 

                                      7

<PAGE>

or reimbursement from, Medicare, Medicaid (Medi-Cal) or other reimbursement 
or payment programs; or if for any other reason said performance should be in 
violation of any statute, ordinance, or be otherwise deemed illegal, by a 
state or federal court or governmental agency (collectively, "Jeopardy 
Event"), then the parties shall use their best efforts to meet forthwith and 
attempt to negotiate an amendment to this Agreement to remove or negate the 
effect of the Jeopardy Event. In the event the parties are unable to 
negotiate such an amendment within fifteen (15) days following such notice, 
then the provisions of this Agreement that give rise to the Jeopardy Event 
shall be ineffective only to the extent that they are in contravention of 
applicable law or otherwise give rise to the Jeopardy Event, without 
invalidating the remaining provisions of this Agreement, unless the same 
should defeat an essential business purpose of this Agreement.

     3.4    TERMINATION BY COMPANY OR PHYSICIAN.  Company or Physician may
terminate this Agreement at any time for "cause." Cause is limited to a material
breach by Sierra of a material term of this Agreement.  In the event Company or
Physician terminates this Agreement for cause, termination shall be effective
upon two (2) weeks notification to Sierra by Company or Physician.  In such
case, upon notification, Sierra shall have a two (2) week period in which to
cure such breach.

     3.5    EFFECT OF TERMINATION.  Unless otherwise set forth below, neither
Company nor  Physician shall be entitled to any severance pay for the services
of Physician upon the termination this Agreement by Sierra for cause.  Company
shall only be entitled to receive accrued but unpaid fees for the services of
Physician through the date of such termination. Upon and after termination of
this Agreement, Physician will be provided full access to copy Sierra patient
medical records in the event of a malpractice action or administrative
investigation or proceeding against Physician.

4.   CONFIDENTIALITY/TRADE SECRETS.  Company and Physician acknowledge that the
position of Physician with the Practice will be one of the highest trust and
confidence both by reason of his position and by reason of his access to and
contact with the trade secrets and confidential and proprietary business
information of Sierra and all of its Affiliates (as defined below), during the
term of this Agreement and thereafter.  Company and Physician covenant and agree
as follows:

     4.1    PROTECTION.  That Company and Physician shall use their best
efforts and exercise utmost diligence to protect and safeguard the trade secrets
and confidential and proprietary information of Sierra and its "Affiliates"
(which term as used in this Agreement shall include any person, corporation,
partnership, general partner or other entity that (i) provides management or
other services to the Practice ("Manager"), or (ii) directly, or indirectly
through one or more intermediaries, controls or is controlled by or is under
common control with Sierra or Manager), including, without limitation, their
trade secrets, proprietary information, the identity of their 

                                      8

<PAGE>

customers and suppliers, their arrangements with their customers and 
suppliers, and their technical data, records, compilations of information, 
processes, computer software, and specifications relating to their customers, 
suppliers, products and services (collectively, "Confidential Information").

     4.2    NONDISCLOSURE.  That neither Company nor Physician shall disclose
any Confidential Information, except as may be required in the course of
Physician's consulting arrangement or as may be required by law.

     4.3    NON-USAGE.  That neither Company nor Physician shall use, directly
or indirectly, for its or his own benefit or for the benefit of another, any
Confidential Information.

     The covenants contained in this Section 4 shall not be applicable to any
information which is in the public domain other than as a result of action by
Company or Physician or which Company or Physician can establish was obtained
from sources other than Sierra or any of its Affiliates, who are not under a
duty of nondisclosure.  All Confidential Information and all files, records,
documents, drawings, specifications, computer software, memorandums, notes, or
other documents relating thereto or otherwise relating to the business of Sierra
and its Affiliates or the Practice, whether prepared by Company or Physician or
otherwise coming into its or his possession, shall be the exclusive property of
Sierra (and/or its Affiliates, as applicable) and shall be delivered to Sierra
or its Affiliates as appropriate and not retained by (nor any copies thereof
retained by) Company or Physician upon termination of the consulting arrangement
hereunder for any reason whatsoever.

5.   NON-SOLICITATION; NON-DIVERSION.

     5.1    PLAN MEMBER CONTACT.  Company and Physician acknowledge and agree
that Sierra has expended a great deal of time, effort and money in developing
its business and obtaining the patients enrolled in prepaid capitated health
plans (each a "Plan Member") that are enrolled with Sierra, and that all of the
patients to whom Physician renders professional medical services pursuant to
this Agreement are and will remain patients of Sierra ("Sierra Patients"). 
Because of this, Sierra considers, and Company and Physician acknowledge, that
the Sierra Patients constitute an important corporate asset and Sierra's Plan
Member lists constitute valuable proprietary information.  In consideration of
Sierra providing current Sierra Patients (I.E. Plan Members), as well as future
Sierra Patients, to Physician, Company and Physician acknowledge and agree that
Sierra will suffer irreparable harm and injury if Company or Physician attempts
to, or does, communicate with Sierra Patients in any way concerning termination
of this Agreement or concerning any other Sierra business matter.  As such,
Company and Physician expressly waive any rights (including those set forth in
California Business and Professions Code Section 651) to contact Sierra Patients
in any way about the termination of this Agreement or about any other Sierra
business matter.  Company and Physician agree that, except to the extent 

                                      9

<PAGE>

that Sierra has provided written authorization, neither Company nor Physician 
shall directly contact Sierra Patients, their employers or health plans in 
regard to business related matters pertaining to Sierra contracted heath 
plans including, but not limited to, (1) switching plans or similar entities 
or contracting directly with Company or Physician (or some other provider 
organization that Physician is a member of) instead of Sierra; (2) the 
options Sierra Patients have to transfer to other plans (or to switch to 
other providers) as a result of termination of this Agreement; or (3) the 
fact that the Sierra Patient will no longer be able to obtain services from 
Physician.  Understanding and acknowledging the foregoing, Company and 
Physician agree to cooperate fully with Sierra in any communications to 
Sierra Patients concerning termination of this Agreement and other Sierra 
business matters, and Company and Physician agree not to interfere in any way 
with the relationship between Sierra and Sierra Patients.  In the event that 
either Company or Physician violates this provision, Sierra may seek a 
temporary restraining order and/or injunction to preclude such activity, as 
well as all appropriate damages resulting from Company's or Physician's 
breach of this provision.  Notwithstanding the foregoing, nothing contained 
herein shall be construed to limit the Physician's opportunity to discuss 
with any Sierra Patient information relevant to such Sierra Patient's medical 
condition, including such Sierra Patient's treatment options, alternative 
plans or other coverage arrangements.

     5.2    NON-SOLICITATION OF PLAN MEMBERS.  As part of the consideration for
Sierra to enter into this Agreement, during the initial and any succeeding term
of this Agreement and for a period of three (3) years following the date of
termination of this Agreement, neither Company nor Physician will directly or
indirectly, either individually or on behalf of or as a provider for any person
or entity other than Sierra whose business competes with the business of Sierra,
(i) advise any Sierra Plan Member or patient to disenroll from Sierra, or
(ii) solicit any Plan Member or patient or any Plan Member's or patient's
employer to become enrolled with any other health maintenance organization,
provider organization, or any other similar hospitalization or medical payment
plan or insurance program.  Company and Physician shall use their best efforts
to ensure that no employee, agent or independent contractor of Company or
Physician makes any derogatory remarks regarding Sierra to any Plan Member, Plan
Member's employer, health plan or health maintenance organization.

     5.3    OTHER AGREEMENTS FOLLOWING TERMINATION.  Nothing contained herein
shall prevent Physician, following the termination of this Agreement, from:

            (a)  Entering into contracts or other agreements with any capitated
health plan that does not have an agreement or contract with Sierra as of the
date of this Agreement; 

            (b)  Providing services to fee for service patients; or 

            (c)   Joining or otherwise becoming a member of an independent
practice association or physician network.

                                      10

<PAGE>

     Notwithstanding the foregoing, in the event a Sierra Patient seeks, without
being solicited or otherwise contacted by Physician or any agent of Physician in
violation of the provisions of Sections 5.1 and 5.2 herein, to receive medical
services from Physician and Physician desires to provide medical services to
such former Sierra Patient, Physician shall only be entitled to provide such
services as an outside provider of Sierra under the terms of Sierra's standard
participating provider agreement then in effect, and pursuant to Sierra's
agreement with the respective health plan under which the capitation payments
for such former Sierra Patient are paid.

6.   REMEDIES FOR BREACH OF COVENANTS OF PHYSICIAN.  The covenants set forth in
Sections 4 and 5 of this Agreement shall continue to be binding upon Company and
Physician notwithstanding the termination of this Agreement  for any reason
whatsoever.  Such covenants shall be deemed and construed as separate agreements
independent of any other provision of this Agreement.  The existence of any
claim or cause of action by Company or Physician against Sierra or any of its
Affiliates, whether predicated on this Agreement or otherwise, shall not
constitute a defense to the enforcement by Sierra or any of its Affiliates of
any or all of such covenants.  It is expressly agreed that the remedy at law for
the breach of any such covenant is inadequate and that temporary and permanent
injunctive relief shall be available to prevent the breach or any threatened
breach thereof, without the necessity of proof of actual damages and without the
necessity of posting a bond, cash or otherwise.  In this connection, Company and
Physician agree not to assert any defense that monetary damages would be
sufficient.

7.   DEFAULT.  Any default by Sierra in the payment when due of any amount owed
by Sierra to Physician under the Contingent Promissory Note, of even date
herewith, issued from Sierra to Physician, in the original principal amount of
$1,125,000, of which $1,068,750 principal amount is currently outstanding, which
default continues for a period of ten (10) days, shall constitute a default
under this Agreement.  Upon written notice from Physician of such default,
Sierra shall have a thirty (30) day period in which to cure such default.  In
the event Sierra fails to cure such default within thirty (30) days of such
notice, at Physician's or Company's option, except for the provisions continued
in Sections 4 and 5 herein above, which shall remain in full force and effect,
this Agreement shall terminate and neither Physician nor Company shall have any
further obligations hereunder.

8.   ARBITRATION.  The parties firmly desire to resolve all disputes arising
hereunder without resort to litigation in order to protect their respective
business reputations and the confidential nature of certain aspects of their
relationship.  Accordingly, any controversy or claim arising out of or relating
to this Agreement, or the breach thereof, shall be settled by arbitration as set
forth below.

     8.1    All disputes which in any manner arise out of or relate to this
Agreement or the subject matter thereof, shall be resolved exclusively by
arbitration in accordance with the 

                                      11

<PAGE>

provisions of this Section 8.  Either party may commence arbitration by 
sending a written demand for arbitration to the other party, setting forth 
the nature of the controversy, the dollar amount involved, if any, and the 
remedies sought, and attaching a copy of this Section to the demand.

     8.2    There shall be one arbitrator.  If the parties shall fail to 
select a mutually acceptable arbitrator within ten (10) days after the demand 
for arbitration is mailed, then the parties stipulate to arbitration before a 
single arbitrator sitting on the Los Angeles, California Judicial Arbitration 
Mediation Services (JAMS) panel, and selected in the sole discretion of the 
JAMS administrator.

     8.3    The parties shall share all costs of arbitration.  The prevailing 
party shall be entitled to reimbursement by the other party of such party's 
attorneys' fees and costs and any arbitration fees and expenses incurred in 
connection with the arbitration hereunder.

     8.4    The substantive law of the State of California shall be applied 
by the arbitrator. 

     8.5    Arbitration shall take place in Los Angeles, California unless 
the parties otherwise agree.  As soon as reasonably practicable, a hearing 
with respect to the dispute or matter to be resolved shall be conducted by 
the arbitrator.  As soon as reasonably practicable thereafter, the arbitrator 
shall arrive at a final decision, which shall be reduced to writing, signed 
by the arbitrator and mailed to each of the parties and their legal counsel.

     8.6    All decisions of the arbitrator shall be final, binding and 
conclusive on the parties and shall constitute the only method of resolving 
disputes or matters subject to arbitration pursuant to this Agreement.  The 
arbitrator or a court of appropriate jurisdiction may issue a writ of 
execution to enforce the arbitrator's judgment.  Judgment may be entered upon 
such a decision in accordance with applicable law in any court having 
jurisdiction thereof.

     8.7    Notwithstanding the foregoing, because time is of the essence of 
this Agreement, the parties specifically reserve the right to seek a judicial 
temporary restraining order, preliminary injunction, or other similar short 
term equitable relief, and grant the arbitrator the right to make a final 
determination of the parties' rights, including whether to make permanent or 
dissolve such court order.

     8.8    The decision and award of the arbitrator shall be kept 
confidential by the parties to the greatest extent possible.  No disclosure 
of such decision or award shall be made by the parties except as required by 
law or as necessary or appropriate to effect the enforcement thereof.

9.   CONTRACTS.  Neither Company nor Physician shall have the right or authority
and each hereby expressly covenants not to, enter into a contract in the name of
Sierra or the Practice or otherwise bind Sierra or the Practice, in any way,
without the express written consent of Sierra.

                                      12

<PAGE>

Company and Physician shall hold Sierra and the Practice harmless from any 
loss attributable to a violation of this covenant.  

10.  USE OF PREMISES.  Company and Physician covenant not to use, or permit any
other personnel under the control of Company or Physician to use, any part of
the premises of the Practice for any purpose other than the performance of
services hereunder.

11.  MEDICAL RECORDS.

     11.1   ENROLLEE RECORDS.  Physician shall maintain the usual and customary
records, in accordance with all applicable federal and state statutory and
regulatory requirements, for each enrollee in the same manner as for other
patients of Physician.  Each enrollee's medical record shall be opened upon the
enrollee's first visit to Physician, and all enrollees' medical records shall be
completed in a timely fashion, be legible, and fully document billed services.

     11.2   ACCESS TO RECORDS.  Subject to applicable federal and state law
regarding privacy and confidentiality requirements, Physician shall, upon
reasonable request, make an enrollee's medical records available to Sierra and
to any contracting health plans, and to each Sierra physician treating the
enrollee and to duly authorized representatives of federal, state and local
governments.

     11.3   CONFIDENTIALITY.  Except as otherwise required by applicable law,
Sierra and Physician agree to keep confidential, and to take the usual
precautions to prevent the unauthorized disclosure of, any and all records
required to be prepared or maintained by  Physician hereunder.

12.  MISCELLANEOUS.

solely to Sierra and contracting health plans for payment for services rendered
to enrollees (excluding non-covered benefits and copayments).  In the event that
Sierra or contracting health plans fail to pay for services as provided in this
Agreement, enrollees shall not be liable to Physician for any services owed to
Physician by Sierra or contracting health plans, and no claim or action of law
shall be maintained by Physician against enrollee for such services rendered to
enrollee.

     12.5   STATUTORY AND REGULATORY REQUIREMENTS.  The parties understand and
agree that they and contracting health plans are subject to the requirements of

be retained by Physician for at least two (2) years, and this obligation shall
continue after termination of this Agreement whether by rescission or otherwise.

     12.7   ACCESS TO BOOKS, RECORDS AND PAPERS.  To the extent required by the
Knox-Keene Health Care Service Plan Act of 1975 and all rules and regulations
adopted pursuant thereto, 

                                      14

<PAGE>

Sierra, any contracting health plan and the Commissioner of Corporations of 
the State of California shall have access at reasonable times upon demand to

     12.8   QUALITY ASSURANCE AND PEER REVIEW.  Physician shall participate in,
cooperate and comply with all applicable requirements of Sierra's and any
contracting health plan's Quality Assurance/Utilization Review Program, which

Agreement, with respect to the subject matter hereof, shall be of any force or
effect.

to be unenforceable or void for any reason, the remainder of the Agreement shall
be unaffected and shall remain in full force and effect in accordance with its
terms, unless such unenforceability or svoidness defeats an essential business
term hereof.

     12.12  NO ASSIGNMENT; BINDING EFFECT.  Neither Company nor Physician shall
assign this Agreement to any other party or parties without the prior written
consent of Sierra.  Except for an assignment to Imperial Bank, a California

     12.14  COUNTERPARTS.  This Agreement may be executed in counterparts, each
of which will be deemed to be an original, but all of which together will
constitute one and the same agreement.

     12.15  CHANGE OF CIRCUMSTANCES.  In the event (i) Medicare, Medicaid
(Medi-Cal), any third-party payor or any federal, state or local legislative or
regulatory authority adopts any law, rule, regulation, policy, procedure or

amount of reimbursement or payment for services under this Agreement, or (ii)
any or all of such payors/authorities impose requirements which require a
material change in the manner of any party's operations under this Agreement
and/or the costs related thereto, then, upon the request of any party materially
affected by any such change in circumstances, the parties shall enter into good
faith negotiations for the purpose of establishing such amendments or
modifications as may be appropriate in order to accommodate the new requirements
and change of circumstances while preserving the original intent of this
Agreement to the greatest extent possible. If, after thirty (30) days of such
negotiations, the parties are unable to reach an agreement as to how or whether
this Agreement shall continue, then any party may terminate this Agreement upon
thirty (30) days prior written notice.

     12.16  COMPLIANCE WITH LAW.  The parties recognize that this Agreement at
all times is to be subject to applicable state, local and federal law.

contracting health plan's evidence of coverage, or by operation of law, and who

termination until: (a) the covered services being rendered by the Physician are
completed; or (b) the contracting health plan or Physician makes reasonable and
medically appropriate provision for the assumption of such covered services by
another participating provider.  Physician shall be compensated for such
services according to the terms of this Agreement.

                              NON-COMPETITION AGREEMENT


     THIS NON-COMPETITION AGREEMENT ("Agreement") is made as of this 1st day 
of June, 1998, by and between Sierra Primary Care Medical Group, A Medical 
Corporation, A California professional corporation, and Prospect Medical 
Holdings, Inc., a Delaware corporation, on the one hand ("Buyers"), and 
PrimeCare Medical Group of Antelope Valley, Inc., a California professional 
corporation, and PrimeCare International, Inc., a Delaware corporation, on 
the other hand ("Sellers").  All capitalized terms used herein and not 
otherwise expressly defined shall have the same meanings set forth in the 
Agreement for the Purchase and Sale of Assets/Transfer of Member 
Responsibility ("Asset Purchase Agreement"), made and entered into as of 
May 13, 1998, by and among Buyers and Sellers.

                                       RECITALS

          A.   Buyers are in the business of developing and operating 
integrated health care delivery systems.  Such systems include primary care 
physicians, specialty care physicians, other outpatient and ancillary 
services providers, and the furnishing of management and administrative 
services to the systems' providers.

          B.   Through its integrated delivery systems, Buyers can contract 
with payors, including capitated payors, to provide the full range of health 
care services to those payors and thereby obtain additional business for 
Buyers and Buyers' contracting providers.

          C.   A key component of the development of an integrated delivery 
system is a strong network of physicians who can provide the necessary 
professional medical services to payors in a designated geographic area.

          D.   To build the physician component of an integrated delivery 
system, Buyers provide a range of alternative services to and have a range of 
relationships with physicians including the recruitment of physicians to a 
designated geographic area, the management of physician practices, the 
acquisition of assets and/or physician practices, the consolidation of 
physician practices, the formation of medical groups, the establishment of 
outpatient clinics, etc.

          E.   Sellers are selling to Buyers and Buyers are buying from 
sellers certain of Sellers' assets pursuant to the Asset Purchase Agreement.

          F.   Buyers desire to purchase such Sellers' assets pursuant to 
Buyers' goal developing and operating an integrated delivery system.

          G.   As a condition to the closing of the Asset Purchase Agreement, 
Sellers shall enter into this Agreement and deliver it to Buyers at the 
Closing, as defined in the Asset Purchase Agreement.

          NOW, THEREFORE, in consideration of the foregoing premises and 
other good and valuable consideration (including a portion of the Purchase 
Price, as defined in the Purchase Agreement, allocated to the covenant not to

parties hereto agree as follows.

1    SELLERS' COVENANTS.  During the term of this Agreement, Sellers (on 
behalf of themselves and any entity or person directly or indirectly 
controlled by Sellers) shall not:

               a.(i) establish, own, or operate an office in the Service 
               Area, as described in Section 4, in which the practice of 
               medicine occurs, (ii) own an interest in any entity or person 
               that establishes, owns, or operates such an office, or (iii) 
               manage or provide management services to such an office;

               b. solicit those physicians that prior to the Closing 
               contracted with Sellers and after the Closing will contract 
               with the Buyers to terminate their contract with Buyers;

               c. solicit those persons that prior to the Closing were 
               employees of Sellers and after the Closing will become 
               employees of Buyers to leave the employ of Buyers;

               d. solicit those persons that prior to the Closing were 
               members of HMOs receiving medical services from physicians who 
               prior to the Closing contracted with  Sellers and after the 
               Closing will receive medical services from Buyers to terminate 
               their relationship with Buyers;

               e. aid or assist any third-party, whether or not for 
               compensation, to do anything that Sellers are prevented from 
               doing as set forth herein;

               f. "Solicit" shall not include general advertisements that do 
               not target specific individuals or general advertisements that 
               do not target those groups of persons that prior to the

               Closing were members of HMOs receiving medical services from 
               Sellers.

          If any term or provision of this Section is determined to be 
illegal, unenforceable or invalid in whole or in part for any reason, such 
illegal, unenforceable or invalid provision or part thereof shall be stricken 
from this Agreement, and such provision shall not affect the legality, 
enforceability or validity of the remainder of this Agreement.  If any 
provision or part thereof of this Agreement is stricken from this Agreement, 
in accordance with the provisions of this Section, then the stricken 
provision shall automatically be replaced, to the extent possible, with a 
legal, enforceable and valid provision which is a similar in tenor to the 
stricken provision as is legally possible.

2    CONFIDENTIALITY.  From and after the closing date, Sellers shall keep 
secret and retain in strictest confidence, and shall not use for the benefit 
of any third party (other than affiliates and successors-in-interest of 
Sellers), except for Buyers or any of Buyers' affiliates, all confidential 
matters and trade secrets known to Sellers relating to the assets that are 
being transferred to Buyers pursuant to the Asset Purchase Agreement 
(collectively, the "Confidential Information").  The Confidential Information

compensation paid to employees and other terms of employment, inventions and 
research projects, and other confidential information of, about, or 
concerning the business and operations of Buyers or any of their affiliates 
learned by Sellers heretofore or hereafter.  Sellers shall not disclose the 
Confidential Information to third parties, other than Buyers and Buyers' 
affiliates, the parties hereto stipulating that as between them the 
Confidential Information consists of important, material and confidential 
trade secrets and affects the successful conduct of the business of Buyers 
and buyers' goodwill.  This Section shall not apply to information in the 
public domain or to information that is sought from Sellers pursuant to 
subpoena or court order (but Sellers must provide notice to Buyers or Buyers' 
affiliates in order for them to contest such subpoenas or court orders).

and warrant that (i) Sellers' covenants set forth in this Agreement are being 
purchased in connection with the sale of the assets to Buyers, and (ii) such 
covenants are reasonable and necessary to protect the legitimate interests of 
Buyers.  Sellers acknowledge that this Agreement is subject to all 


                                      3

                              Attention: Dale S. Miller, Esq.

     6.7  GOVERNING LAW.  This Agreement shall be governed by and construed in
accordance with the laws of the State of California.

     6.8  INJUNCTIVE RELIEF.  The parties hereto acknowledge and agree that a 
breach by Sellers of this Agreement will cause irreparable damage to Buyers, 
the exact amount of which will be difficult to ascertain, and that remedies 
at law for any such breach will be inadequate.  Accordingly, Sellers agrees 
that if Sellers breach this Agreement, then Buyers shall be entitled to 
injunctive relief, and Sellers agree not to assert in any proceeding that 
Buyers have an adequate remedy at law.  Sellers shall pay the reasonable fees 
and expense, including attorneys' fees, incurred by Buyers or any successor 
or assign in enforcing this Agreement.

     6.9  SEVERABILITY.  If any provision or portion of this Agreement is 
held by a court of competent jurisdiction to be invalid or unenforceable, the 
remainder of this Agreement will nevertheless continue in full force and 
effect and shall not be invalidated or rendered unenforceable or otherwise 
adversely affected, unless such invalidity or unenforceability would defeat 
an essential business purpose of this Agreement.  Without limiting the 
generality of the foregoing, if the provisions of this Agreement shall be 
deemed to create a restriction which is unreasonable as to either duration or 
geographical area, or both, the parties agree that the provisions of this 
Agreement shall be enforced for such duration and in such geographical area 
as any court of competent jurisdiction may determine to be reasonable.

     6.10 ATTORNEYS' FEES.  Should either Buyers or Sellers institute any 
action or procedure to enforce this Agreement or any provisions hereof, or 
for damages by reason of any alleged breach of this Agreement or of any 
provision hereof, or for a declaration of rights hereunder (including without 
limitation arbitration), the prevailing party in any such action or 
proceeding shall be entitled to receive from the other party all costs and 
expenses, including without limitation reasonable attorneys' fees, incurred 
by the prevailing party in connection with such action or proceeding.

          IN WITNESS WHEREOF, the parties hereto have executed this Agreement 
as of the day and year first written above.

amended from time to time. Subject to Section 12.11 herein, PacifiCare shall
notify IPA of any material amendments to the Secure Horizons Medical and
Hospital Plan, which amendments shall become effective upon thirty (30) days
written notice by PacifiCare to IPA, and IPA has not objected to PacifiCare in
writing within the thirty (30) day period to be bound by such amendments. IPA
approval of such amendments shall not be unreasonably withheld. If IPA does
provide PacifiCare reasonable written objection to be bound by such amendments

          2.02  LIABILITY FOR OBLIGATION - Notwithstanding any other section or
provision of this Agreement, nothing contained herein shall cause either party
to be liable or responsible for any debt, liability, or obligation of the other

IPA is an independent contractor relationship. Neither IPA nor members,

neither PacifiCare nor any employee or agent of PacifiCare is a member, partner,
employee or agent of IPA. As such, all medical decisions are rendered solely by
IPA and not by PacifiCare. IPA is solely responsible for all Medical Services
arranged by IPA and provided to Subscribers. None of the provisions of this
Agreement shall be construed to create a relationship of agency, representation,
joint venture, ownership, control of employment between the parties other than
that of independent parties contracting solely for the purpose of effectuating
this Agreement.

          2.04  DUTY TO DEFEND AND INDEMNIFY - To the extent not covered by

damage, cost, expense or liability arising out of or related to the performance
or nonperformance by IPA, its Specialist Physicians or employees of any Medical
Services to be performed or arranged by IPA under this Agreement. It is
understood and agreed by PacifiCare that the foregoing

indemnification obligation is in no way whatsoever intended to reduce or
eliminate any insurance coverage maintained by IPA and that PacifiCare shall be
entitled to indemnification from IPA only for claims, losses, damages, costs,
expenses or liabilities in excess of the applicable insurance policy limits or
arising from uninsured events or occurrences.

           To the extent not covered by insurance maintained by IPA, whether
because of liability in excess of the policy limits or because of the occurrence
of a non-insured event, PacifiCare shall defend, indemnify and hold harmless IPA
from and against any claims, loss damage, cost, expense or liability arising out
of or related to the performance or nonperformance of PacifiCare, its employees
or agents of any service to be performed or provided by PacifiCare under this
Agreement. It is understood and agreed by IPA that the foregoing indemnification
obligation is in no way whatsoever intended to reduce or eliminate any insurance
coverage maintained by PacifiCare and that IPA shall be entitled to
indemnification from PacifiCare only for claims, losses, damages, costs,
expenses or liabilities in excess of the applicable insurance policy limits or
arising from uninsured events or occurrences.

     3.   DUTIES OF IPA

           3.01 IPA RESPONSIBILITIES - IPA agrees to arrange for or provide
Medical Services twenty-four (24) hours a day in coordination with PacifiCare
and with Hospital and other providers, as necessary, for each Subscriber who has

financially responsible for all Medical Services specified in Attachment A2,
incorporated in full herein by reference, provided to Subscribers for whom IPA
is to receive a monthly Capitation Payment from PacifiCare based upon the
PacifiCare provided Eligibility List. IPA shall be responsible for determining
whether Subscribers are eligible for Medical Services on the basis of the most

Member Physicians shall be provided by professional personnel and at physical

credentialed to practice in the State of California.

          3.03 INSURANCE - IPA shall maintain professional liability insurance
and general liability insurance in the minimum amounts of one million dollars

coverage, for its agents and employees, as applicable. In the event IPA procures
a claims made policy as distinguished from an occurrence policy, IPA shall
procure and maintain prior to termination of such insurance continuing "tail"
coverage, unless successor policy coverage provides such "tail" protection.   
IPA shall provide PacifiCare with evidence of such insurance coverage upon
PacifiCare's request. IPA shall immediately notify PacifiCare of any material
changes in insurance coverage and shall provide a certificate of such insurance
coverage to PacifiCare upon PacifiCare's reasonable request. In the event IPA
contracts with independent contractor physicians to provide Medical Services
under this Agreement, IPA will require such independent contractor physicians
and their agents to maintain professional liability insurance and general
liability insurance in the minimum amounts as is usual and customary in the
community.

          3.04 REFERRALS - IPA shall refer Subscribers in need of specialty care
services only with the approval of the IPA Utilization Review Committee.

with Section 3.05 below.

          3.05 HOSPITAL ADMISSIONS - Whenever IPA determines that a Subscriber
on IPA's eligibility list requires Hospital Services which are not Emergency
Services, IPA shall arrange for such Hospital admissions and outpatient
surgeries through the IPA's Utilization Review Committee and its developed
utilization review program. IPA and its Member Physicians shall not serve as
admitting physicians for any Subscriber without such prior approval except in
the event that Emergency Services are required. If IPA or a Member Physician
admits a Subscriber to a Hospital for Emergency Services, IPA shall notify
PacifiCare of such admission within the time frames as required in the

          3.06 ELIGIBILITY LIST - IPA shall accept as patients those Subscribers
who are on IPA's eligibility list provided by PacifiCare to IPA. Member
Physicians and IPA shall be entitled to rely on the most current provided list
until a new list has been provided to IPA. IPA understands that in order to
update the eligibility list, PacifiCare is dependent on the receipt of
information from HCPA.

          3.07 COLLECTION OF CHARGES FROM SUBSCRIBERS - IPA shall collect
applicable Copayments from Subscribers upon the rendition of Medical Services to
Subscribers pursuant to the Secure Horizons Medical and Hospital Plan. With the
exception of Copayments and charges for non-covered services delivered on a
fee-for-service basis to Subscribers, IPA shall in no event, including, without
limitation, to non-payment by PacifiCare, insolvency of PacifiCare, or breach of
the Agreement, bill, charge, collect and deposit, or attempt to bill, charge,
collect or receive any form of payment, from any Subscriber for Medical Services
provided pursuant to this Agreement and for which Subscriber is entitled under
the Secure Horizons Medical and Hospital Plan in effect for such Subscriber.

          IPA shall not maintain any action at law or equity against a
Subscriber to collect sums owed by PacifiCare to IPA. Upon notice of any such
charge, PacifiCare may terminate this Agreement consistent with the provisions
contained in Section 7.01.02 and take all other appropriate action consistent
with the terms of this Agreement to eliminate such charges, including, without
limitation, requiring IPA and Specialist Physicians to return all sums collected
as Surcharges from Subscribers or their representatives. Nothing in this
Agreement, however, shall be construed to prevent IPA from providing non-covered
Medical Services on a usual and customary fee-for-service basis to Subscribers.

          IPA'S obligations regarding the collection of charges from Subscribers
shall survive the termination of this Agreement with respect to Medical Services
provided during the term of the Agreement without regard to the cause of
termination of this Agreement.

          3.08 COLLECTION OF CHARGES FROM THIRD PARTIES WHEN MEDICARE NOT THE
PRIMARY PAYOR - IPA and Member Physicians accept payment from PacifiCare (plus
applicable Copayments) for Medical Services as provided herein as full payment
for such Medical Services from PacifiCare except as provided herein; provided
however, when Medicare is not the primary payor for Medical Services, such as
when the Subscriber is entitled to payment from another third party or for
payment for a Workers' Compensation claim, or from other primary insurance
coverage maintained by Subscriber, IPA and Member Physicians shall make no
demand upon PacifiCare for reimbursement under the Individual Subscriber Stop
Loss Program as specified in Attachment A3 hereto until all primary sources of
payment have been pursued and it is determined that full payment cannot be
obtained within the (10) months from the date of the provision of Medical
Services.

this Agreement, subject to the following conditions:

                3.08.01 IPA shall not commence any legal or equitable action
against a third party without obtaining the prior written consent of PacifiCare.
It is agreed that collection or demand letters consistent with the PacifiCare
Provider Policies and Procedures Manual shall not constitute the commencement of
legal or equitable action.

                3.08.02 IPA shall defend, indemnify and hold PacifiCare harmless
for all actions by IPA which relate to collections of an account pursuant to
this Section 3.08.

                3.08.03 IPA shall perform such collection activities consistent
with the procedures set forth in the PacifiCare Provider Policies and Procedures
Manual.

                3.08.04 PacifiCare may immediately rescind such assignment on a
claim-by-claim basis for any reason by providing written notice of recision to
IPA.

                In the event IPA receives payment from a third party after
receipt of payment from PacifiCare, IPA shall reimburse PacifiCare to the extent
that the combined amounts received from all payors exceeds one hundred percent
(100%) of IPA's usual and customary fee-for-service charges.

          3.09 DUTIES OF IPA UPON TERMINATION DURING PHASE-OUT PERIOD - Should

7.01.01(b), IPA shall be released of its obligation to continue to provide or
arrange for Medical Services to Subscribers during the phase-out period as
stated in this Section 3.09. If this Agreement is terminated for any other
reason by either party or if this Agreement terminates at the end of the Initial
Term or any renewal term, IPA shall not be released of its obligation to
continue to provide or arrange for Medical Services to Subscribers during the
phase-out period, which phase-out period shall end on the earlier of:

          3.10 CONTINUING CARE RESPONSIBILITIES - IPA and Member Physicians 
shall provide or arrange for Medical Services to Subscribers for the term of 
this Agreement in accordance with Section 3.01 hereof. In the event of 
termination of this Agreement and the expiration of IPA's duty to provide or 
arrange for Medical Services during the phase-out period pursuant to Section 
3.09, if applicable, IPA and Member Physicians shall continue to provide or 
arrange for Medical Services to Subscribers until the effective date of 
transfer of such Subscribers to another Participating Medical Group for 
further treatment and written notice of such transfer has been provided by 
PacifiCare to IPA. If a Subscriber's care cannot be transferred for the 
reason of hospitalization of Subscriber, continuity of care, or other legally 
required medical treatment reasons, IPA shall continue to provide or arrange 
for Medical Services for such Subscriber until PacifiCare, through 
consultation with the Subscriber's attending participating physician, has 
made provision for the transfer of such Subscriber to another participating 
provider for further Medical Services and has notified IPA of such transfer 
in writing. The payment provisions for any continued Medical Services after

any recourse against a Subscriber for Medical Services provided after PacifiCare
ceases operation. This continuation of Medical Services obligation shall be for
the period for which Subscriber Premiums have been paid, but shall not exceed a
period of thirty (30) days, except for those Subscribers who are hospitalized on
an inpatient basis as provided below.

          In the event PacifiCare ceases operations or IPA terminates this 
Agreement on the basis of PacifiCare's failure to make timely Capitation 
Payments, IPA shall continue to arrange for Medical Services to those 
Subscribers who are hospitalized on an inpatient basis at the time PacifiCare 
ceases operations or IPA terminates the Agreement until such Subscribers are 
discharged from the hospital. IPA may file a claim with PacifiCare for such 
Medical Services at [  **  ] of IPA's usual and customary fee for service 
charges then in effect.

          IPA agrees that the provisions of this Section 3.10 and IPA's
obligations herein shall survive the termination of this Agreement without
regard to the cause of termination of the Agreement, and shall be construed to
be for the benefit of the Subscribers.

                         a.   FINANCIAL FAILURE OF IPA - PacifiCare's reasonable

(180) days of the effective date of termination of this Agreement as provided
herein, an accounting shall be made by PacifiCare of monies due and owing either

equipment, books and records relating to the performance of this Agreement,

inspection.

          8.05  CITATIONS - IPA shall notify PacifiCare in writing of each and
every report of any governmental or quasi-governmental agency with jurisdiction

provide to PacifiCare, within forty five (45) days of the end of each calendar
year, copies of its audited annual financial statements.

     9.   EXCLUSIVITY

          9.01  UTILIZATION OF IPA BY PACIFICARE - Nothing in this Agreement
shall be construed to require PacifiCare to assign any minimum or maximum number
of Subscribers to IPA, nor to require PacifiCare to utilize the Medical Services
of IPA for any or all Subscribers in the IPA Service Area.

     10.  GOVERNING LAW AND DISPUTE RESOLUTION

          10.01 GOVERNING LAW - This Agreement and the rights and obligations of

          10.02 DISPUTES BETWEEN IPA AND SUBSCRIBER NOT GOVERNED BY AGREEMENT -
Any controversies or claims between IPA and Subscriber arising out of IPA's
performance of this Agreement are not governed by this Agreement.  IPA and
Subscriber may seek any appropriate legal action to resolve such controversy or
claim deemed necessary.

          In the event of a dispute between IPA and a Subscriber and upon mutual
agreement between IPA and such Subscriber, PacifiCare agrees to make available
the Subscriber Grievance Resolution Process described in the Secure Horizons
Medical and Hospital Plan Agreement for resolution of such dispute.  In such
instance, the decision of the PacifiCare Subscriber Satisfaction Committee and
Board of Directors shall not be binding upon the parties except upon agreement
between IPA and the Subscriber. Nor shall such grievance be subject to binding
arbitration except upon agreement between the parties. Should IPA and Subscriber
fail to resolve the grievance, IPA and Subscriber may seek any appropriate legal
action deemed necessary by such party.

          10.03 PAYMENT DISPUTES INVOLVING IPA - In the event IPA fails to make
a payment to a Specialist Physician within sixty (60) days of the submission of
the bill by Specialist Physician to IPA and the validity and the amount of the
submitted bill are undisputed, PacifiCare may, in its sole and absolute
discretion, elect to pay the Specialist Physician on behalf of IPA and deduct
such payment from IPA's next monthly Capitation Payment.

          Should a dispute concerning a claim for payment for Medical Services
rendered to Subscribers arise between IPA and a Specialist Physician who is a
Participating Medical Provider, IPA or the Specialist Physician may submit a
written complaint to PacifiCare. The complaint shall describe the disputed
claims and the basis for the amounts claimed and include the applicable written
agreement between IPA and the Specialist Physician. PacifiCare shall investigate
the complaint and make a determination of whether or not the claim is valid and
should be paid.  In the event PacifiCare determines that IPA owes any amount to
Specialist Physician, IPA shall make such payment within thirty (30) days of
PacifiCare's termination. If IPA fails to pay the amount due within this thirty
(30) day period, PacifiCare may deduct the amount owed from IPA's next monthly
capitation payment. This amount will temporarily be placed in an account (the
"Claims Dispute Account") which shall be established by PacifiCare.  If IPA or
Specialist Physician wishes to contest PacifiCare's determination, either may do
so by initiating an action for binding arbitration and notifying PacifiCare of
such initiation within thirty (30) days of PacifiCare's determination. If IPA or
Specialist Physician fails to request arbitration within thirty (30) days or if
the arbitration affirms PacifiCare's decision that amounts are owing from IPA to
Specialist Physician, PacifiCare shall release from the Claims Dispute Account
the amount owing to Specialist. If the arbitration results in a decision that no
money or a lesser amount than was determined by PacifiCare is owing to
Specialist Physician, PacifiCare shall release to IPA the amounts which were
erroneously withheld from IPA's Capitation Payment.

          In the event this Agreement has been terminated prior to PacifiCare's
investigation and written determination and PacifiCare's investigation results
in a determination that IPA owes money to Specialist Physician, PacifiCare may,
in its sole and absolute discretion, elect to pay Specialist Physician on behalf
of IPA and seek reimbursement from IPA.

demand, require or seek directly or indirectly the transfer, discharge, or

of, Medically Necessary Medical or Hospital Services, except in accordance with

between IPA and PacifiCare consistent with the Secure Horizons Medical and
Hospital Plan.

          12.04 CONFIDENTIAL AND PROPRIETARY INFORMATION

                12.04.01  INFORMATION CONFIDENTIAL AND PROPRIETARY TO
PACIFICARE - IPA acknowledges that all PacifiCare Subscribers participating in a
Secure Horizons Medical and Hospital Plan individually or through an employer
group and receiving Medical Services shall be Subscribers of PacifiCare.
Subscriber and employer group information shall include, without limitation, the
names, addresses and telephone number of all Subscribers; member, employer and
administrative service manuals and all forms related thereto; and records, files
(other than patient medical files) and lists contained in IPA and PacifiCare
files.

                IPA acknowledges that all such information is confidential and
proprietary to PacifiCare and that such Subscriber and employer group
information contains valuable trade secrets of PacifiCare.

                All PacifiCare Subscriber agreements and the information
contained therein regarding PacifiCare, IPA, employer groups, Subscribers or the
financial arrangements between a hospital, IPA and PacifiCare is confidential
and proprietary to PacifiCare.

                IPA shall maintain all Subscriber information and other
PacifiCare trade secret information confidential. IPA shall not disclose or use
any confidential and proprietary information for its own benefit or gain either
during the term of this Agreement or after the date of termination of this
Agreement; provided, however, that IPA may use the name, address and telephone
number or other medical information of a PacifiCare Subscriber if Medically
Necessary for the proper treatment of such Subscriber or upon express prior
written permission of PacifiCare or the Subscriber.

                12.04.02  INFORMATION CONFIDENTIAL AND PROPRIETARY TO IPA - IPA
shall provide PacifiCare with a written description of all information
proprietary to IPA which is confidential and contains trade secrets of IPA ("IPA
Information"). PacifiCare shall maintain IPA Information confidential.
PacifiCare shall not disclose or use any IPA Information for its own benefit
either during the term of this Agreement or after the effective date of
termination of this Agreement.  Upon termination of this Agreement, PacifiCare
shall provide and return to IPA all IPA Information in its possession in a
manner to be specified by IPA. PacifiCare shall cooperate with IPA in
maintaining the confidentiality of IPA Information at all times.

                12.04.03  SOLICITATION OF PACIFICARE SUBSCRIBERS OR EMPLOYER
GROUPS - IPA shall not directly or indirectly engage in the practice of
solicitation or the patronage of PacifiCare's Subscribers or employer groups
without PacifiCare's prior written consent. Solicitation shall mean conduct by
an officer, agent, employee or Member Physician of IPA or its assignee or
successor during the Initial Term or any subsequent term of this Agreement and
continuing for a period of one (1) year after the effective date of termination
of this Agreement which may be reasonably interpreted as designed to persuade
PacifiCare Subscribers to discontinue their Subscriber agreements with
PacifiCare or to continue to receive health care from IPA on a fee-for-service
basis or to encourage PacifiCare Subscribers to participate


                                       - 22 -

<PAGE>

in the prepaid health service plan offered by IPA, or any other prepaid health
service plan (the "Solicitation").  The breach of this Section 12.O4.03 during

pursuant to Section 7.01.02 of this Agreement.

          12.05 CONFIDENTIALITY OF THIS AGREEMENT - To the extent reasonably
possible, each party agrees to maintain this Agreement as a confidential

benefits hereunder shall not be assigned, transferred, pledged, or hypothecated
in any way by IPA or PacifiCare and shall not be subject to execution,
attachment or similar process, nor shall the duties imposed herein be
subcontracted or delegated without the written consent of the other party.
Notwithstanding, PacifiCare may assign, transfer, pledge or hypothecate this
Agreement and its rights, interests and benefits hereunder to any entity which
has at least majority control of PacifiCare or to any entity of which PacifiCare
has at least majority control.

          12.07 INVALIDITY OF SECTIONS OF AGREEMENT - The unenforceability or
invalidity of any paragraph or subparagraph of any section or subsection of this
Agreement shall not affect the enforceability and validity of the balance of
this Agreement.

          12.08 WITHDRAWAL OF SUBSCRIBERS BY PACIFICARE - PacifiCare reserves
the right to withdraw from IPA all or part of the Subscribers from IPA whose
Medical Services are not being properly provided pursuant to this Agreement.
PacifiCare shall provide written notice to IPA of such withdrawal and the
reasons therefore. PacifiCare shall then allow IPA thirty (30) days from the
date of such notice to correct deficiencies. If such deficiencies are not
corrected to PacifiCare's satisfaction within said period, PacifiCare may
withdraw its Subscribers as provided in this Section 12.08 and remove IPA's name
from PacifiCare's marketing materials.

          12.09 TRANSFER OF SUBSCRIBERS - PacifiCare and IPA shall exercise
reasonable efforts in discouraging Subscriber transfers except at reenrollment
periods, or when a Subscriber can show just cause for such transfer and
PacifiCare agrees to such transfer. Nevertheless, PacifiCare may require
transfer of Subscribers assigned to IPA for any reason; or, IPA may request
transfer of Subscribers assigned to it by PacifiCare to other IPAs for cause or
if the capacity of IPA is overburdened so that the provision of Medical Services
as required by this Agreement is affected; all such transfers shall be
consistent with the PacifiCare Provider Policies and Procedures Manual.

notice to IPA in order to maintain compliance with applicable federal and state
laws; provided, however, any such amendment which affects a material duty or
responsibility of IPA and has a material adverse economic effect upon IPA as
reasonably demonstrated by IPA to PacifiCare, shall be subject to the provisions
of Section 12.12 below.

          12.12 MODIFICATIONS OF THIS AGREEMENT AND/OR PACIFICARE PROVIDER
POLICIES AND PROCEDURES MANUAL AND/OR PACIFICARE HEALTH PLAN - Anything to the
contrary herein notwithstanding, in the event of any material modification of
this Agreement and/or the PacifiCare Provider Policies and Procedures Manual

responsibility and reimburses the material economic detriment caused to IPA. In

shall not be effective.

          12.13 TERMS; SECTIONS - Unless otherwise indicated, all terms in any
appropriate attachments, addendum and amendments hereto shall have the same
meaning attributed to such terms in the body of this Agreement and references to
section numbers are to the appropriate sections of this Agreement.

     b.   Costs incurred by IPA for Medical Services provided during the last

     For purposes of this Agreement, the Cost of Care for Medical Services

     b) [  **  ] of the fees actually paid, if the services are rendered by 
providers other than IPA.

     IPA shall provide PacifiCare with a copy of IPA's fee-for-service fee 
schedule and shall notify PacifiCare thirty (30) days prior to the effective 
date of any changes in such fee schedule. The amount of increase of IPA's 
fees shall be limited to [  **  ] per Year for purposes of any calculations

     1.   Services provided by IPA which are not a benefit, as specified in the

          Compensation, or any other source including Copayments, shall not be
          included in the Cost of Care. If, at a later date, these claims are
          not collectible, or only partially collectible, then these services
          will be included in the relevant programs, based on the Cost of Care
          calculation cited above.

In the event that the annual Hospital Services Expense exceeds the annual 
Hospital Services Budget, PacifiCare shall pay IPA the Withhold Amount, if 
any, minus an amount equal to [  **  ] of the amount by which the Hospital 
Services Expense exceeds the Hospital Services Budget, up to a limit of 
[  **  ] of the annual Hospital Services Budget.

          To the extent that the portion of the calculated deficit for which IPA
is responsible exceeds the Withhold Amount, IPA shall not be entitled to any of
the Withhold Amount. After the Withhold Amount has been exceeded, any remaining
portion of the deficit for which IPA is responsible shall be carried forward
into the succeeding term. An amount equal to this remaining portion of the
deficit will be withheld from IPA's monthly Capitation Payment, using a mutually
agreed upon payment schedule, not to exceed one (1) year.

          Should this Agreement terminate leaving no successive term to carry
forward an existing deficit amount, such deficit amount shall be due and payable
by IPA to PacifiCare within one hundred fifty (150) days of the effective date
of termination of this Agreement.

     e.   SETTLEMENT OF HOSPITAL INCENTIVE PROGRAM PAYMENTS

          PacifiCare shall make interim Hospital Incentive Program 
calculations and payments, if any, on a [  **  ] within sixty (60) days after 
the end of each [  **  ] from the Effective Date. The Hospital Services 
Expense figure used in [  **  ] incentive program calculations shall also 
include an "Incurred But Not Reported" factor in order to account for 
outstanding Medical Services claims. PacifiCare shall make an annual Hospital 
Incentive Program payment to IPA within one hundred and fifty (150) days of 
the end of each Year.

     f.   MEDICAL SERVICES RESERVE FUND REPAYMENT

If the medical group borrows against the Medical Services Reserve Fund, the
monies borrowed will be subtracted from the final surplus of the Hospital
Incentive Program. If the Hospital Incentive Program results in a

deficit, the amount owed to PacifiCare from the Medical Services Reserve Fund
will be carried forward to the next year's Hospital Incentive Program in
addition to the deficit.

                               CAPITATION PAYMENT RATES

     The monthly Capitation Payment which PacifiCare shall pay IPA shall equal:

     [  **  ] of both the Monthly HCFA Payment and any applicable Subscriber 
     Premiums, less [  **  ] of the Monthly HCFA Payment as payment for the
     premium for Individual Stop-Loss coverage specified in Attachment "A3" 
     hereto, and also less [  **  ] for the Pharmacy Control Program as 
     specified in Attachment E hereto.  The payment per Subscriber per month by
     PacifiCare to IPA shall be increased or decreased by PacifiCare to reflect
     increases or decreases made by HCFA in the Monthly HCFA Payment. PacifiCare
     shall make monthly retroactive adjustments in IPA's succeeding Capitation
     Payment to reflect the retroactive adjustments made by HCFA in the HCFA 
     Payment, if any.

     PacifiCare shall provide IPA appropriate documentation in support of the
actual Capitation Payment made.  Should IPA desire additional billing
information, PacifiCare shall make available for inspection other mutually
agreed upon documents, upon thirty (30) days prior written notice from IPA. IPA
shall have the right to reasonably audit PacifiCare's books and records directly
relating only to IPA's Capitation Payment determinations upon thirty (30) days
prior written notice at IPA's sole expense.

MAMMOGRAPHY SERVICES

     IPA shall receive [  **  ] for each screening and diagnostic mammography 
study performed above the 1987 PacifiCare wide baseline, specific to the 
Secure Horizons Medical and Hospital Plan, for such studies. This baseline 
equals two hundred sixty-seven (267) studies per one thousand (1,000) adult 
females per Year. The amount due to IPA shall be calculated based upon 
utilization data submitted by IPA and shall be paid within one hundred fifty 
(150) days of the end of the Year.

INSTITUTION-TO-INSTITUTION TRANSFERS

     IPA shall bill PacifiCare and PacifiCare shall pay for Medical Services 
provided to Subscribers who designate IPA as their Participating Medical 
Group through a transfer from another PacifiCare Participating Medical Group 
and who are in a skilled nursing facility, acute care hospital, or are 
receiving any other type of acute institutional care at time of designating 
IPA as their Participating Medical Group. Medical Services provided by IPA to 
such Subscribers shall be reimbursed under this special program, until the 
Subscriber is discharged from such institution, at [  **  ] of IPA's ordinary 
and customary fee-for-service rates then in effect but no greater than the 
ISL deductible (as specified in Attachment A3) per Subscriber during the 
Initial Term or any subsequent term of this Agreement.

     IPA shall batch these bills together and identify the bills as
institution-to-institution prior to submitting bills to PacifiCare. Bills must
be submitted to PacifiCare no later than sixty (60) days from the provision of
Medical Services. Expenses for Medical Services identified as
institution-to-institution and rendered from January 1, 1990 through December
31, 1990 only will be included in the institution-to-institution program. A
final claim must be filed for such Medical Services by March 31, 1991 to be
reimbursed under this institution-to-institution program.

                               PHARMACY CONTROL PROGRAM

     The purpose of the Pharmacy Control Program (PCP) is to provide an
incentive to the IPA to foster the efficient utilization of prescription
services. The PCP gives the IPA the ability to share in any savings when
comparing actual utilization against an established budget.

     The budget will be set at ______________ ($   ) on a per Subscriber per
month (pmpm) basis and will be calculated based on the number of Subscribers who
have designated IPA as their Participating Medical Group and who are eligible to
receive the prescription benefit.

     Debited against this budget will be the actual expenses paid by 
PacifiCare for pharmacy services of those Subscribers who have designated IPA 
as their Participating Medical Group for the applicable month. The IPA will 
share [  **  ] of any savings in comparing the budget and actual expenses. 
PacifiCare shall provide, on a quarterly basis, utilization reports 
pertaining to the cost of prescriptions written on a physician specific 
basis. A final calculation and final payment will be made within one hundred 
fifty (150) days of the end of each Year.

     IPA agrees to participate in a generic drug substitution program and
formulary program established by PacifiCare's Quality Assurance Committee.

                         DIVISION OF FINANCIAL RESPONSIBILITY


     The attached template outlines the division of financial responsibility
between IPA, Hospital and PacifiCare, the intent being to clarify Medical
Services and Medical Service categories in order to provide for accurate
administration.  As it is impossible to include every Medical Service available,
the template serves as a model under which broad Medical Service categories
suggest the appropriate financial responsibility for Medical Services or items
not specifically listed.

     NOW THEREFORE, the Agreement shall be amended as follows:

1.   The following definitions shall be added to Section One of the
     Agreement.

     SECURE HORIZONS POINT-OF-SERVICE PLAN COVENANT NOT TO COMPETE

     IPA will receive an additional [  **  ] of the Monthly HCFA Payment

     the monthly capitation payment by this [  **  ] commencing the
     month in which this breach occurs.

The effective date of this Amendment shall be January 1, 1996.

By signing below, both parties hereto have executed and agreed to this

                SECURE HORIZONS POINT-OF-SERVICE PLAN CONTROL PROGRAM


1.   INTRODUCTION

The Secure Horizons Point-of-Service Plan Control Program is designed to provide
a financial incentive for the control of In-Network Hospital Services and
Out-of-Network Services provided to Secure Horizons Point-of-Service Plan
Members.

Secure Horizons Point-of-Service Plan Subscriber months and related In-Network
Hospital Service expenses shall not be included in calculating the Conventional
Utilization Control Program described in Attachment A5.

2.   DEFINITIONS

The following terms shall have the meanings set forth below when utilized in
this Attachment A6.

a.   SECURE HORIZONS POINT-OF-SERVICE PLAN BUDGET - shall equal [  **  ] of the 
     Monthly HCFA Payment, less [  **  ] of the Reinsurance Premium specified in
     Paragraph 5.05 of this Agreement for In-Network Hospital Services 
     reinsurance.

b.   ACTUAL COSTS consist of:

     i.   In-Network Hospital Services costs incurred during the period of
          calculation for which PacifiCare has received a claim and paid net of
          discounts; In-Network Hospital Services incurred prior to the period
          of calculation and paid during the current period; and for quarterly
          interim calculations, In-Network Hospital Services incurred during the
          period for which PacifiCare has received a claim but has not paid,
          less an average aggregate discount factor (for year-end calculations,
          only paid claims will be included); LESS Subscriber claim costs in
          excess of the reinsurance deductible specified above; PLUS

     ii.  Claims paid charges for Out-of-Network Services incurred during the
          current period; and claims paid charges for Out-of-Network Services
          incurred but not included in prior period Secure Horizons

                                        4

<PAGE>

     iii. Third party liability and coordination of benefit recoveries for
          In-Network Hospital Services and Out-of-Network Services that are
          received during the period of calculation.

c.   BUDGET SAVINGS - is the difference between the Secure Horizons
     Point-of-Service Plan Budget and Actual Costs, to the extent
     Actual Costs are less than the Secure Horizons Point-of-
     Service Budget.

3.   SAVINGS DISTRIBUTION

To the extent Budget Savings are available, such savings shall be shared between
IPA and PacifiCare as follows:

IPA shall receive [  **  ] between actual Capitation Payments for Secure
Horizons Point-of-Service Plan Subscribers for the period and the amount of
Capitation Payments the IPA would have received if the Secure Horizons
Point-of-Service Plan Subscribers were enrolled in the Conventional Plan. The
above distribution to IPA shall be limited to the Budget Savings available
pursuant to the Secure Horizons Point-of-Service Plan Control Program
calculation. Additionally, IPA shall receive [  **  ] of any remaining Budget
Savings after reimbursing IPA up to the [  **  ] amount.

4.   BUDGET DEFICITS.  IPA shall have [  **  ] financial responsibility in the 
event that Actual Costs exceed the Secure Horizons Point-Of-Service Plan Budget.

5.   PERIODIC CALCULATIONS - The Secure Horizons Point-Of-Service Plan Control
Program shall be administered on an IPA-specific basis. For IPAs with multiple
IPA Facilities, the program shall be calculated for each IPA Facility. However,
Budget Savings and payment distributions shall be based on IPA's consolidated
results.

Cumulative calculations of the Secure Horizons Point-Of-Service Plan Control 
Program results will be based on calendar quarters and shall be calculated 
within one hundred and twenty (120) days of the end of each calendar quarter, 
except for the fourth quarter for which no calculation or payment will be 
made in anticipation of the year-end settlement. Interim distribution 
payments will be made within one hundred and twenty (120) days following the 
end of each quarter, except for the fourth quarter, and will be limited to 
[  **  ] of calculated Budget Savings to account for incurred but not received 
claims. Year-end calculations and payments of the Secure Horizons 
Point-of-Service Plan Control Program shall be made within one hundred eighty 
(180) days of the end of each calendar year.

                        BENEFIT WITHHOLD INCENTIVE PROGRAM
                        ----------------------------------

     The purpose of the Benefit Withhold Incentive Program (BWIP) is to 
provide an incentive to the IPA to foster the efficient utilization of the 
following Subscriber benefits:

              1)  Outpatient prescription drugs
              2)  Acute hospital days greater than 150/year
              3)  Respite Care
              4)  Immunosuppressive drugs
              5)  Mammography (see Section E of Attachment C)

     The BWIP gives the IPA the ability to share in any savings when 
comparing actual utilization against the budgeted withhold amount.

     The budget will be set at [  **  ] of the monthly revenue received from 
HCFA for Subscribers who have designated IPA as their Participating Medical 
Group.

     Debited against this budget will be the actual expenses paid by 
PacifiCare for the earmarked benefits list above in this Attachment for 
Subscribers who have designated IPA as their Participating Medical Group for 
the applicable month. The IPA will share [  **  ] of any savings in comparing 
the budget and actual expenses. PacifiCare shall provide, on a quarterly 
basis, utilization reports pertaining to the cost of prescriptions written on 
a physician specific basis. A final calculation and final payment will be 
made within one hundred fifty (150) days of the end of each Year.

     IPA agrees to participate in a generic drug substitution program and 
formulary program established by PacifiCare's Quality Assurance Committee.

                     DIVISION OF FINANCIAL RESPONSIBILITY


The attached template outlines the division of financial responsibility 
between IPA, the Hospital Incentive Program (HIP), and PacifiCare (PC), the 
intent being to clarify Medical Service and Hospital Service categories in 
order to provide for accurate administration. As it is impossible to include 
every service available, the template serves as a model under which broad 
Medical Service and Hospital Service categories suggest the appropriate 
financial responsibility for services or items not specifically listed.

                                 ATTACHMENT A4

                                 COST OF CARE

For purposes of this Agreement, the Cost of Care for Medical Services 
provided or arranged by IPA to Subscribers shall equal:

    a)   For services provided to Subscribers by Member Physicians who 
         practice at IPA Facilities, [  **  ] of the Medicare Locality 
         Fee Schedule for Participating Providers as published by the 
         Part B carrier.

    b)   For services provided to Subscribers by Specialist Physicians or
         Outside Providers, [  **  ] of the fees actually paid by IPA.

General guidelines and special situations:

    1.   Services provided by IPA which are not a benefit, as specified in 
         the Subscriber's Secure Horizons Medical and Hospital Agreement, will
         not be considered a part of Cost of Care.

    2.   The Cost of Care of Anesthesia Professional Services rendered by IPA 
         shall be set at [  **  ] of usual and customary charges. The Cost of 
         Care for Anesthesia Professional Services rendered through an outside 
         referral or reciprocity referral shall be set at [  **  ] or [  **  ] 
         of usual and customary charges, whichever is higher.

    3.   Any Medical Services provided where payment is considered 
         collectible through the coordination of benefits, third-party 
         liability, Worker's Compensation, or any other source including 
         Copayments, shall not be included in the Cost of Care. If, at a 
         later date, these claims are not collectible, or only partially 
         collectible, then these services will be included in the relevant 
         programs, based on the Cost of Care calculation cited above.

                   IPA MEDICARE SHARED RISK SERVICES AGREEMENT


The Undersigned parties to the PacifiCare IPA Medicare Partial Risk Services 
Agreement between PacifiCare of California ("PacifiCare") and Santa 
Ana-Tustin Physician's Group, Inc. ("IPA") do hereby amend said Agreement as 
follows:

1.    Paragraph 1.03 is amended to read as follows:

      1.03 CATASTROPHIC CASE - is any single medical condition, including 
complications arising from such medical condition, where the total cost of 
Health Care Services to treat such condition is expected to exceed [  **  ] 
per condition, regardless of payment source.

2.    Paragraph 3.02 is amended in full to read as follows:

      3.02 STANDARDS - All Medical Services arranged for or provided by IPA 
and its Member Physicians shall be provided by professional personnel and at 
physical facilities according to generally accepted standards of medical 
practice and management in the community. IPA further agrees to provide or 
arrange for Referrals to Specialist Physicians and facilities as are 
necessary, appropriate, and in accordance with generally accepted standards of 
medical practice in the community in compliance with the standards developed 
by PacifiCare's Quality Assurance Committee. If IPA contracts with Specialist 
Physicians to provide Medical Services under this Agreement, IPA shall 
require such Specialist Physicians to provide IPA with the credentialing 
information set forth herein. IPA shall obtain and maintain information 
concerning each Member Physician's and Specialist Physician's education, 
training, references, malpractice liability insurance, hospital staff status, 
hospital clinical privileges, and hospital staff reappointment dates. Such 
information shall be kept in a form prescribed by or acceptable to 
PacifiCare. Upon request, the credentialing information shall be made 
available to PacifiCare for review or copying.

      IPA acknowledges and agrees that it shall report Member Physicians or 
Specialist Physicians as required by the California Business and Professions 
Code Section 805 ("Section 805"). IPA further agrees to maintain and 
demonstrate to PacifiCare upon request compliance with the following:

      3.02.01 IPA shall use best efforts to ensure that its Member Physicians 
and Specialist Physicians are licensed by the State of California and have 
current Drug Enforcement Agency ("DEA") registration. IPA shall immediately 
notify PacifiCare in writing of any of the following actions taken by or 
against a Member

                                           1

any malpractice claim of more than ten thousand dollars ($10,000); and (vi) 
a change in hospital staff status or hospital clinical privileges, including 
any restrictions or limitations.

      3.02.02 In the event that it is determined by PacifiCare that IPA does

agrees to assist PacifiCare in obtaining credentialing information concerning 
each Member Physician's and Specialist Physician's education, training, 
references, malpractice liability insurance, hospital staff status, hospital 
clinical privileges, and hospital staff reappointment dates. IPA shall 
obtain from each Member Physician and Specialist Physician a signed waiver, 
acceptable to PacifiCare, allowing PacifiCare access to such credentialing 
information at any acute care hospital or health care facility. If IPA is 
unable to obtain a signed waiver from a Member Physician or Specialist 
Physician, IPA shall obtain the credentialing information directly from the 
acute care hospital or health care facility and make such information 
available to PacifiCare upon request for review and copying.

      3.02.03 IPA agrees to provide access to continuing education programs 
for its Member Physicians and Specialist Physicians in accordance with the 
standards established by the California Medical Association for continuing 
education. The content and delivery of such continuing education programs

standards for the delivery of Medical Services pursuant to this Agreement. 
IPA further agrees to gather, correlate, and distribute to its Member 
Physicians and Specialist Physicians, information regarding professional 
medical activities and developments which IPA believes may be of assistance 
in providing Medical Services pursuant to this Agreement.

      3.02.04 IPA agrees to provide reasonable evidence that all nurses and 
other ancillary and paramedical personnel who are employed by and contract 
with IPA or Specialist Physicians are properly licensed by the State of 
California.

3.    Paragraph 5.02 is amended to read as follows:

reference.

To the extent that each party owes an amount to the other party in the risk 
programs noted above, IPA agrees that PacifiCare shall combine the results of 
all applicable risk programs such that one aggregate payment is payable to or 
receivable from IPA.  A fully detailed accounting of the results of each 
program shall accompany the aggregate payment or notice of amount due.

4.   Attachment A4 COST OF CARE - is amended in part to read as follows:

                              HOSPITAL SERVICES

    Hospital Services are authorized by IPA, are initially paid by PacifiCare 
    and, except as otherwise indicated, are the financial responsibility of 
    PacifiCare and IPA. A summary of most Hospital Services includes the 
    following:

         1.   INPATIENT HOSPITAL CARE - Medically Necessary inpatient 
              hospital care, as defined by Medicare, but limited to a total 
              of one hundred fifty (150) days per Subscriber per Year. 
              Unlimited days of inpatient hospital care shall be provided to 
              Subscribers, but PacifiCare shall be financially responsible 
              for days in excess of one hundred fifty (150) days. Subscriber 
              shall be assigned semi-private units, unless medical necessity 
              dictates private accommodations. Where the Subscriber requests 
              private accommodations, not required for medical purposes, the 
              incremental difference in fee-for-service rates shall be the 
              responsibility of the Subscriber. A summary of inpatient care 
              includes:

              a.   Medical/Surgical Care, Intensive Care, Cardiac Care and 
                   other special care units (including Hospital Services 
                   associated with non-experimental transplants as defined 
                   by Medicare);

              b.   Inpatient psychiatric;

              c.   Nursing Services, meals, drugs, medications (excluding take-
                   home medications), blood transfusions;

              d.   Medical and Surgical supplies and appliances;

              e.   Inpatient rehabilitation services, such as: inpatient 
                   physical, occupational and speech therapy;

              f.   Inpatient alcohol and drug treatment and rehabilitation.

         2.   SKILLED NURSING - Medically Necessary Skilled Nursing Facility 
              care, as defined by Medicare. Patients shall be assigned 
              semi-private units, unless medical necessity dictates private 
              accommodations. Where the Subscriber requests private 
              accommodations, not required for medical purposes, the 
              incremental difference in the fee-for-service rates shall be 
              the responsibility of the Subscriber. Skilled nursing 
              facilities must be Medicare licensed and approved.

              Attachment A).

         4.   TRANSPORTATION EXPENSES - Medicare approved ambulance services 
              provided within the IPA Service Area for Subscribers. When a 
              transfer of Subscriber from one facility to another is authorized
              by IPA or PacifiCare, the cost of such transfer shall be a 
              Hospital service. The method of transfer shall be determined by 
              IPA, but IPA shall coordinate all Subscriber transfers to or 
              from Hospital with designated Hospital personnel. Also included 
              are paramedic services in emergency cases in the IPA Service

              inpatient medical and other Medical Services which may not be 
              delayed until facilities or physicians of the Hospital or IPA 
              (or alternatives authorized by IPA) can be used without possible 
              serious effects to the health of the Subscriber. Such services 
              must be Medically Necessary Emergency Services.

         6.   HOME HEALTH CARE - As determined to be Medically Necessary, as 
              defined by Medicare and provided in lieu of hospitalization, as 
              mutually agreed to by IPA, Hospital and PacifiCare, including 
              any required DME and IV Therapy Services.

         7.   HOSPICE CARE - Should be coordinated with Medicare for special 
              reimbursement provisions.

         8.   OUTPATIENT SURGERY - Facility, supply charges and the 
              professional component of a hospital based physician service

         9.   END STAGE RENAL DISEASE - Facility and professional charges for 
              inpatient and outpatient dialysis services for Subscribers who

              b.   Treatment programs for outpatient substance abuse as defined 
                   by Medicare.

                     PacifiCare which are found on appeal or arbitration 
                     through the Subscriber grievance resolution process to 
                     be Hospital Services which the Subscriber was entitled

                       BENEFIT WITHHOLD INCENTIVE PROGRAM

      The purpose of the Benefit Withhold Incentive Program (BWIP) is to 
provide an incentive to the IPA to foster the efficient utilization of the 
Subscriber benefits outline in Attachment C, Section A "BENEFIT WITHHOLD", 
most particularly prescription drugs. The BWIP gives the IPA the ability to 
share in any savings when comparing actual utilization against the budgeted 
withhold amount.

      The budget will be set at [  **  ] of the monthly revenue received from 
HCFA for Subscribers who have designated IPA as their Participating Medical 
Group.

      Debited against this budget will be the actual expenses paid by 
PacifiCare for the earmarked benefits as outlined in Attachment C of those 
Subscribers who have designated IPA as their Participating Medical Group for 
the applicable month. The IPA will share [  **  ] of any savings in comparing 
the budget and actual expenses. PacifiCare shall provide, on a quarterly 
basis, utilization reports pertaining to the cost of prescriptions written on 
a physician specific basis. A final calculation and final payment will be 
made within one hundred fifty (150) days of the end of each Year.

      IPA agrees to participate in a generic drug substitution program and 
formulary program established by Pacificare's Quality Assurance Committee.

     NOW THEREFORE, the parties agree to amend the Agreement as set forth 
below.

arising from uninsured events or occurrences.

     3.   DUTIES OF IPA

          3.01  IPA RESPONSIBILITIES - IPA agrees to arrange for or provide
Health Care Services twenty-four (24) hours a day in coordination with
PacifiCare for each Subscriber who has designated IPA as his or her
Participating Medical Group. IPA shall be financially responsible for all
Medical Services provided to Subscribers for whom IPA should receive a monthly
Capitation Payment from PacifiCare based upon the PacifiCare provided

by IPA and its Member Physicians shall be provided by professional personnel and

standards developed by PacifiCare's Quality Assurance Committee. IPA agrees to
maintain and demonstrate to PacifiCare upon request, throughout the term of this
Agreement, compliance with the following:

                3.02.01   IPA shall ensure that its Member Physicians and
Specialist Physicians maintain licensure under the laws of the State of

                3.02.02   IPA agrees to provide continuing education programs
for its Member Physicians and Specialist Physicians in accordance with the
standards established by the California Medical Association for continuing

ancillary and paramedical personnel who are employed by and contract with IPA or

          3.03  INSURANCE - IPA shall maintain professional liability insurance
and general liability insurance in the minimum amounts of One Million Dollars
($1,000,000) per person, Three Million Dollars ($3,000,000) per occurrence
coverage, and Three Million Dollars ($3,000,000) combined single limits
coverage, for its Member Physicians providing Health Care Services to
Subscribers on behalf of IPA. In the event IPA procures a claims made policy as
distinguished from an occurrence policy, IPA shall procure and maintain prior to
termination of such insurance, continuing "tail" coverage, unless successor
policy coverage provides such "tail" protection. IPA shall immediately notify
PacifiCare of any material changes in insurance coverage and shall provide a
certificate of such insurance coverage to PacifiCare. In the event IPA contracts
with independent contractor physicians and Specialist Physicians to provide
Health Care Services under this Agreement, IPA will require such independent
contractor physicians and Specialist Physicians and their agents to maintain
professional liability insurance and general liability insurance in the minimum
amounts as is usual and customary in the community.

          3.04  REFERRALS - IPA shall refer Subscribers in need of specialty
care services only with the approval of the IPA Utilization Review Committee.
However, in the event that Emergency Services are required, IPA shall comply
with Section 3.05 below.

on IPA's Eligibility List requires Hospital Services that are not Emergency
Services, IPA shall arrange for such Hospital admissions and outpatient
surgeries through the IPA's Utilization Review Committee and its developed
utilization review program. IPA and its Member Physicians shall not serve as
admitting physicians for any Subscriber without such prior approval except in
the event that Emergency Services are required. If IPA or a Member Physician
admits a Subscriber to a Hospital for Emergency Services,


                                        - 6 -

<PAGE>

IPA shall notify PacifiCare of such admission within the time frames as required

applicable Copayments from Subscribers upon the rendition of Medical Services to
Subscribers pursuant to the PacifiCare Health Plan. With the exception of
Copayments and charges for non-covered services delivered on a fee-for-service
basis to Subscribers, IPA shall in no event, including, without limitation,
non-payment by PacifiCare, insolvency of PacifiCare, or breach of the Agreement,
bill, charge, collect and deposit, or attempt to bill, charge, collect or
receive any form of payment, from any Subscriber for Medical Services provided
pursuant to this Agreement and for which Subscriber is entitled under the
PacifiCare Health Plan in effect for such Subscriber.

          IPA shall not maintain any action at law or equity against a
Subscriber to collect sums owed by PacifiCare to IPA. Upon notice of any such
charge, PacifiCare may terminate this Agreement consistent with the provisions
contained in Section 7.01.02 and take all other appropriate action consistent
with the terms of this Agreement to eliminate such charges, including, without
limitation, requiring IPA and Specialist Physicians to return all sums collected
as Surcharges from Subscribers or their representatives. Nothing in this
Agreement, however, shall be construed to prevent IPA from providing non-covered
Medical Services on a usual and customary fee-for-service basis to Subscribers.

          IPA's obligations regarding the collection of charges from Subscribers
shall survive the termination of this Agreement with respect to Health Care
Services provided during the term of the Agreement without regard to cause of
termination of this Agreement. Except as provided elsewhere herein, these
obligations shall not apply to services provided after the Agreement has been
terminated and the phase-out period has expired pursuant to Section 3.09, if
applicable.

          3.08  COLLECTION OF CHARGES FROM THIRD PARTIES - IPA and Member
Physicians accept payment from PacifiCare (plus applicable Copayments) for
Medical Services as provided herein as full payment for such Medical Services;
provided however, in the event the Subscriber is entitled to payment from
another third party or for payment for a Workers' Compensation claim, or from
other primary insurance coverage maintained by Subscriber, IPA and Member
Physicians shall make no demand upon PacifiCare for reimbursement under the
Individual Subscriber Stop Loss Program as specified in Attachment A3 hereto
until all primary sources of payment have been pursued and it is determined that
full payment cannot be obtained within ten (10) months from the date of the
provision of Medical Services.

                3.08.02   IPA shall not commence any legal or equitable action
against a third party without obtaining the prior written consent of PacifiCare.
It is agreed that collection or demand letters consistent with the PacifiCare
Provider Policies and Procedures Manual shall not constitute the commencement of
legal or equitable action. Under no circumstances shall IPA commence any legal
action against a Subscriber to obtain payment for Health Care Services.

                3.08.03   IPA shall defend, indemnify and hold PacifiCare
harmless for all actions by IPA pursuant to this Section 3.08.

                3.08.04   IPA shall perform such collection activities
consistent with the procedures set forth in the PacifiCare Provider Policies and
Procedures Manual.

                3.08.05   PacifiCare may rescind such assignment in total or on
a claim-by-claim basis by providing written notice of rescission to IPA.

                In the event IPA receives payment from a third party, a 
workers' compensation carrier or a primary insurer after receipt of payment 
from PacifiCare, IPA shall reimburse PacifiCare to the extent that the 
combined amounts received from all payors exceeds [  **  ] of IPA's usual and 
customary fee-for-service charges.

          3.09  DUTIES OF IPA UPON TERMINATION DURING PHASE-OUT PERIOD - Should

7.01.01(b), IPA shall be released of its obligation to continue to provide or
arrange for Health Care Services to Subscribers during the phase-out period as
stated in this Section 3.09. If this Agreement is terminated for any other
reason by either party or if this Agreement terminates at the end of the Initial

                3.09.01   Twelve (12) months from the effective date of
termination of this Agreement, or

                3.09.02   The date PacifiCare has secured the transfer of
Subscribers to another medical group, individual practice association, or
physician for further treatment, and has notified IPA of such transfer in
writing.

          Compensation during the phase-out period shall be as otherwise
specified in this Agreement for the provision of Medical Services until such a
time that IPA's enrollment falls below [  **  ] of the


                                        - 8 -

<PAGE>

enrollment on the effective date of termination, or [  **  ], whichever is 
greater.  Effective the first day of the month in which enrollment falls 
below the above mentioned levels, the payment provisions shall convert to 
[  **  ] of fee-for-service rates and all elective admissions and outpatient 
surgeries shall be coordinated with PacifiCare on a prior authorization basis.

          3.10  CONTINUING CARE RESPONSIBILITIES - In the event of 
termination of this Agreement and the expiration of IPA's duty to provide or 
arrange Health Care Services during the phase-out period pursuant to Section 
3.09, if applicable, IPA and Member Physicians shall continue to provide or 
arrange for Health Care Services to Subscribers until the effective date of 
transfer of such Subscribers to another Participating Medical Provider for 
further treatment and written notice of such transfer has been provided by 
PacifiCare to IPA. If a Subscriber's care cannot be transferred for the 
reason of Subscriber hospitalization, continuity of care, or other legally 
required medical treatment reasons, IPA shall continue to provide or arrange 
for treatment for the Subscriber until PacifiCare has made provision for the 
transfer of such Subscriber to another Participating Medical Provider for 
further treatment and has notified IPA of such transfer in writing. The 
payment provisions for any continued treatment after expiration of the 
phase-out period shall be the lesser [  **  ] of the usual and customary fees 
of the treating physician or the Cost of Care as set out in Attachment A4, 
attached hereto and incorporated in full herein by reference.

                Notwithstanding the above or any other provisions to the
contrary, IPA agrees that in the event PacifiCare ceases operations for any
reason, including insolvency, IPA shall provide or arrange Health Care Services
and shall not bill, charge, collect or receive any form of payment from any
Subscriber or have any recourse against a Subscriber for Health Care Services
provided after PacifiCare ceases operations. This continuation of Health Care
Services obligation shall be for the period for which premium has been paid, but
shall not exceed a period of thirty (30) days, except for those Subscribers who
are hospitalized on an inpatient basis as provided below.

                In the event PacifiCare ceases operations or IPA terminates
this Agreement on the basis of PacifiCare's failure to make timely Capitation
Payments, IPA shall continue to arrange for Health Care Services to those
Subscribers who are hospitalized on an inpatient basis at the time PacifiCare
ceases operations or IPA terminates this Agreement until such Subscribers are
discharged from the hospital. IPA may file a claim with PacifiCare for such
services as previously specified in this Section 3.10.

                IPA agrees that the provisions of this Section and IPA's and
Member Physicians' obligations herein shall survive the termination of this
Agreement without regard to the cause of termination of the Agreement, and shall
be construed to be for the benefit of the Subscribers.

          3.11  STAFF PRIVILEGES - IPA agrees to have its Member Physicians
seek and obtain (and provide evidence of) staff privileges or other appropriate
access to Hospitals where Health Care Services shall be provided to Subscriber

to be bound by such amendments. IPA approval of such amendments shall not be
unreasonably withheld.  If IPA does provide PacifiCare reasonable written

use IPA's name, address, telephone number, and a listing of IPA's Member
Physicians and Specialist Physicians in any informational material routinely
distributed to Subscribers and for other purposes related to the administration

<PAGE>

the amount of the submitted bill are undisputed, PacifiCare may, in its sole and
absolute discretion, elect to pay the Specialist Physician on behalf of IPA and
deduct such payment from IPA's next monthly Capitation Payment.

rendered to Subscribers arise between IPA and a Specialist Physician who is a
Participating Medical Provider, IPA or the Specialist Physician, may submit a
written complaint to PacifiCare. The complaint shall describe the disputed claim
and the basis for the amounts claimed and include the applicable written
agreement between IPA and the Specialist Physician. PacifiCare shall investigate
the complaint and make a determination of the whether or not the claim is valid
and should be paid.  In the event PacifiCare determines that IPA owes any amount
to Specialist Physician, IPA shall make such payment within thirty (30) days of
PacifiCare's determination. If IPA fails to pay the amount due within this
thirty (30) day period, PacifiCare may deduct the amount owed from IPA's next
monthly capitation payment.  This amount will temporarily be placed in an
account (the "Claims Dispute Account") which shall be established by PacifiCare.
If IPA or Specialist Physician wishes to contest PacifiCare's determination,
either may do so by initiating an action for binding arbitration and notifying
PacifiCare of such initiation within thirty (30) days of PacifiCare's
determination. If IPA or Specialist Physician fails to request arbitration
within thirty (30) days or if the arbitration affirms PacifiCare's decision that
amounts are owing from IPA to Specialist Physician, PacifiCare shall release
from the Claims Dispute Account the amount owing to Specialist. If the
arbitration results in a decision that no money or a lesser amount than was
determined by PacifiCare is owing to Specialist Physician, PacifiCare shall
release to IPA the amounts which were erroneously withheld from IPA's Capitation
Payment.

          In the event this Agreement has been terminated prior to PacifiCare's
investigation and written determination and PacifiCare's investigation results
in a determination that IPA owes money to Specialist Physician, PacifiCare may,
in its sole and absolute discretion, elect to pay Specialist Physician on behalf
of IPA and seek reimbursement from IPA through arbitration as described in
Section 10.01.

without PacifiCare's prior written consent. Solicitation shall mean conduct by
an officer, agent, employee or Member Physician of IPA or its assignee or
successor during the Initial Term or any subsequent term of this Agreement and
continuing for a period of one (1) year after the effective date of termination
of this Agreement which may be reasonably interpreted as designed to persuade
PacifiCare Subscribers or employer groups to discontinue their Subscriber or
group agreements with PacifiCare or to continue to receive health care services
from IPA on a fee-for-service basis or to encourage PacifiCare Subscribers or
employer groups to participate in the prepaid health service plan offered by
IPA, or any other prepaid health service plan (the "Solicitation"). The breach
of this Section 12.05.03 during any term of this Agreement shall be grounds for
termination of this Agreement pursuant to

Section 7.01.02 of this Agreement.  IPA's provision of executive physicals and
provision of Health Care Services pursuant to industrial medicine contracts
shall not be in violation of this Section 12.05.03.

          12.06 CONFIDENTIALITY OF THIS AGREEMENT - To the extent reasonably
possible, each party agrees to maintain this Agreement as a confidential
document and not to disclose the Agreement or any of its terms without the
approval of the other party.

          12.07 ASSIGNMENT - This Agreement and the rights, interests, and
benefits hereunder shall not be assigned, transferred, pledged, or hypothecated
in any way by IPA or PacifiCare and shall not be subject to execution,
attachment or similar process, nor shall the duties imposed herein be
subcontracted or delegated without the written consent of the other party.
Notwithstanding, PacifiCare may assign, transfer, pledge or hypothecate this
Agreement and its rights, interests and benefits hereunder to any entity which
has at least majority control of PacifiCare or to any entity of which PacifiCare
has at least majority control.

          12.08 INVALIDITY OF SECTIONS OF AGREEMENT - The unenforceability or
invalidity of any paragraph or subparagraph of any section or subsection of this
Agreement shall not affect the enforceability and validity of the balance of
this Agreement.

          12.09 WITHDRAWAL OF SUBSCRIBERS BY PACIFICARE - PacifiCare reserves
the right to withdraw from IPA all or part of the Subscribers from IPA whose
Health Care Services are not being properly provided or arranged pursuant to
this Agreement. PacifiCare shall provide written notice to IPA of such
withdrawal and the reasons therefore. PacifiCare shall then allow IPA thirty
(30) days from the date of such notice to correct deficiencies. If such
deficiencies are not corrected to PacifiCare's satisfaction within said period,
PacifiCare may withdraw its Subscribers as provided in this Section 12.09 and
remove IPA's name from PacifiCare's marketing materials.

          12.10 TRANSFER OF SUBSCRIBERS - PacifiCare and IPA shall exercise
reasonable efforts in discouraging Subscriber transfers except at re-enrollment
periods, or when a Subscriber can show just cause for such transfer and
PacifiCare agrees to such transfer. Nevertheless, PacifiCare may require
transfer of Subscribers assigned to IPA for any reason; or, IPA may request
transfer of Subscribers assigned to it by PacifiCare to other IPAs for cause or
if the capacity of IPA is overburdened so that the provision of Health Care
Services as required by this Agreement is affected.

          12.11 CAPTIONS - Captions in this Agreement are descriptive only and
do not affect the intent or interpretation of the Agreement.

          12.12 AMENDMENT - This Agreement may be amended or modified only by
mutual written consent of the parties. Notwithstanding the foregoing sentence,
PacifiCare may amend this Agreement upon sixty (60) days written notice to IPA

                                  HOSPITAL SERVICES

Hospital Services are initially paid by PacifiCare.  The financial
responsibility for Hospital Services is shared between PacifiCare and IPA
pursuant to the Hospital Control Program as set forth in Attachment A5. A
summary of some Hospital Services includes the following:

     1.   INPATIENT HOSPITAL CARE - Inpatient hospital care, as determined to be
          Medically Necessary. Subscriber shall be assigned semi-private units,
          unless medical necessity dictates private accommodations. Where the
          Subscriber requests private accommodations, not required for medical
          purposes, the incremental difference in fee-for-service rates shall be
          the responsibility of the Subscriber. A summary of inpatient care
          includes:

          a.    Medical/Surgical Care, Intensive Care, Cardiac Care and other
                special care units (including hospital services associated with
                non-experimental transplants as defined by the federal Office
                of Prepaid Healthcare guidelines);
          b.    Nursing Services, meals, drugs, medications (excluding
                take-home medications), blood transfusions;

                occupational and speech therapy.
          e.    Detoxification

     2.   SKILLED NURSING - Skilled nursing facility care, as determined to be
          Medically Necessary. Patients shall be assigned semi-private units,
          unless medical necessity dictates private accommodations. Where the
          Subscriber requests private accommodations, not required for medical
          purposes, the incremental difference in the fee-for-service rates 
          shall be the responsibility of the Subscriber.

     3.   HOSPITAL BASED PHYSICIAN SERVICE - All hospital based physician
          services where the physician provides the professional component of an
          inpatient hospital based service, the hospital outpatient surgery
          center service, or a free-standing surgery center service. The charges
          of an anesthesiologist are not included as a Hospital Service. (See
          paragraph 7 below in this Attachment A1.)

     4.   TRANSPORTATION EXPENSES - Approved ambulance services provided within
          the IPA Service Area for Subscribers. When transfer of a Subscriber
          from one facility to another is authorized by IPA or PacifiCare, the
          cost of such transfer shall be a Hospital service. The method of
          transfer shall be determined by IPA, but IPA shall coordinate all
          Subscriber transfers to or from Hospital with designated Hospital
          personnel.    Also included are paramedic services in emergency cases

          effects to the health of the Subscriber. Such services must be

                             INDIVIDUAL STOP-LOSS PROGRAM

1.   The Individual Stop-Loss ("ISL") Program is designed to limit the IPA's 
costs per Subscriber per year to a specified amount (the "deductible"). 
PacifiCare will assume all financial responsibility for the Subscriber in 
excess of the deductible by paying IPA, based on the payment procedure as 
outlined below, [  **  ] in excess of the deductible of the Cost of Care, as 
defined in Attachment A4, included in full herein by reference.

3.   Payment Procedures:

     a.   IPA must submit claims data in accordance with the procedures
          specified in the PacifiCare Provider Policies and Procedures Manual;
          such claims must be submitted no later than ninety (90) days from the

          program.

     b.   Costs incurred by IPA for Medical Services provided during the last
          thirty-one (31) days of the Year for which no benefits were payable
          under the ISL Program because such costs were applicable to the
          deductible may be carried forward for inclusion in the ISL
          calculations for the next succeeding Year;

     c.   Medical Services rendered in connection with Worker's Compensation
          cases or where payments for Medical Services provided under Section
          3.01 of this Agreement are receivable through the coordination of
          benefits, third party liability, or any other source of income,
          including copayments, shall not be included in the Cost of Care
          provided in calculating stop-loss liability;

     d.   PacifiCare will determine and pay all ISL Program claims within sixty
          (60) days of receipt of a complete claim;

     e.   For continuing ISL cases (i.e., cases where more than one payment is
          made during the Year), PacifiCare will reimburse the IPA quarterly
          based on the submittal of a continuing ISL claim.

     f.   If the Subscriber transfers in the middle of the Year to another
          Participating Medical Group and then exceeds the ISL, the payment for
          all Medical Services in excess of the ISL will be shared
          proportionately among the Participating Medical Groups who provided
          Medical Services to the Subscriber during the Year.

                                     COST OF CARE

     For purposes of this Agreement, the Cost of Care for Medical Services
rendered by IPA to Subscribers shall equal:

          a)    [  **  ] of the fees charged by IPA to IPA's fee-for-service 
patients for the same or similar services, if the same or similar services 
are rendered by IPA; or

          b)    [  **  ] of the fees actually paid, if the services are 
rendered by providers other than IPA.

     IPA shall provide PacifiCare with a copy of IPA's fee-for-service fee 
schedule and shall notify PacifiCare thirty (30) days prior to the effective 
date of any changes in such fee schedule. The amount of increase of IPA's 
fees shall be limited to [  **  ] per Year for purposes of any calculations 
pursuant to this Agreement, regardless of the actual percentage increase in 
IPA's fees each Year.

     IPA shall notify PacifiCare of the existence and payment or discount
provisions of any agreements between IPA and other providers who render Medical
Services to Subscribers.

                            HOSPITAL CONTROL PROGRAM (HCP)

1.   INTRODUCTION

The Hospital Control Program is designed to provide a financial incentive for
the control of inpatient, in-area emergency services and selected other
outpatient services.  When actual incurred costs, when compared to a
predetermined budget, are favorable then the savings are shared with the IPA.
Conversely, when actual incurred costs exceed the budget, then the IPA also
shares the additional costs. Limitations are included at both the individual
member level (through the payment of a reinsurance premium for specific stop
loss) and at the aggregate level (through a percentage limitation on overall
shared savings or losses) to mitigate extraordinary performance fluctuations.

3.   ACTUAL COSTS

Actual costs are defined for purposes of this Program as HCP - included
services, incurred during the calendar year that are:

     a.   Paid, at net paid by PacifiCare
     b.   Received and unpaid as of the run date of the HCP settlement
          calculation at gross amount billed.
     c.   IPA authorized services from the immediate prior calendar year which,
          due to their late submission to PacifiCare, were not included in the
          prior year cost calculation.
                                   LESS:
     d.   member costs in excess of the reinsurance deductible specified above.
     e.   Third party recoveries received during the period that are associated
          with current or prior year's settlements.
     f.   An estimated amount to account for discounts and Copayments expected
          to be received on the unpaid claims included as actual costs.

4.   CALCULATION OF SAVINGS AND LOSSES

The earned budget detailed on the previous page will be adjusted to reflect 
the actual number of members who are enrolled in the 880 Plan. The inpatient 
hospital component of the budget is stated assuming [  **  ] of the members 
enrolled in the 880 Plan and [  **  ] of the members in all other plans.

In the event that actual costs are less than the earned budget, then the IPA
shall receive the share of savings relative to the bed days per thousand members
per year indicated in the following sliding scale schedule:

<TABLE>

[  **  ]                    [  **  ] 

</TABLE>

For the purposes of this calculation, "Bed Days/Outpt. Surgery" shall be
defined as acute inpatient days plus outpatient surgeries, net of any acute
inpatient days or outpatient surgeries which are covered under reinsurance or
are paid through a third party recovery or through coordination of benefits.

If actual costs are greater than the earned budget, then the IPA will be liable
for [  **  ] of the amount lost up to the maximum payment specified below.

On a quarterly basis, cumulative calculations of the Hospital Control Program 
results will be made and interim payments will be made based on these 
results. Calculations will be made in accordance with the contractual terms 
above and the amount of PacifiCare's payment will be [  **  ] of the amount 
due to the IPA based on the above referenced calculation. The reduced payment 
amount is to adjust for the incurred, but not reported, claims.

In the event that the interim calculation reflects a cumulative loss for the 
IPA, no interim payment will be made to or due from the IPA in the first 
quarter a loss results.    If a cumulative loss is reflected for two 
consecutive quarters, the IPA will make an interim payment of [  **  ] of the 
cumulative amount due to PacifiCare.

The calculations will be made based on calendar quarters and the interim 
payments made within sixty (60) days thereof. No interim calculation will be 
made in the fourth calendar quarter. If the IPA reflects a loss for two 
consecutive quarters and, therefore, is required to make a payment to 
PacifiCare, such payment will be due within fifteen (15) days of the IPA's 
receipt of such notice form PacifiCare. A calendar year-end calculation of 
the Hospital Control Program shall be made by PacifiCare and payment to the 
appropriate party shall be made within 120 days of the end of the calendar 
year. 

5.   MONTHLY REPORTING

PacifiCare will distribute a report monthly, on or before the 15th, that lists
the payments made during the previous month for services included in the HCP.

6.   SPECIAL CONDITIONS FOR EMERGENCY SERVICES

If the IPA and/or its participating physicians direct a PacifiCare member to use
the emergency services of a hospital, and PacifiCare determines that the use of
those services was inappropriate, PacifiCare reserves the right to deduct the
professional component of the PacifiCare payment from the IPA's capitation as a
penalty for improper referral. When an inappropriate referral for emergency
services has been determined by PacifiCare, a written conformance request will
be forwarded to the IPA. The conformance request Will serve as notice that all
subsequent inappropriate referrals may have the penalty applied. IPA will be
notified and given the opportunity to respond to a pending claim of improper
referral prior to the implementation of any penalty deduction.

7.   Any hospital or emergency expenses that are considered third party
liability, Worker's Compensation claims, etc., shall not be included in the
calculations. If, at a later date, these claims are not collectible, then an
adjustment will be made in the calculations.

8.   Calculations shall not include unauthorized admissions whereby a Member is
admitted by a non-participating or non-referring physician in a non-emergency
status or out-of-area hospitalization.

                               CAPITATION PAYMENT RATES

     The monthly Capitation Payment which PacifiCare shall pay IPA shall 
equal IPA's cumulative shares of the Percent of Premium. The Percent of 
Premium designated by PacifiCare for payment for Medical Services shall equal 
[  **  ] of the gross premiums billed by PacifiCare each month for coverage 
of Subscribers designating IPA as their Participating Medical Group pursuant 
to the PacifiCare Health Plan, not including the Supplemental Benefit 
Premium, less [  **  ] in consideration of the Individual Stop Loss Program 
noted in Attachment A3 hereto, and also less necessary consideration as 
determined by PacifiCare for supplemental benefits for which IPA assumes no 
financial responsibility. IPA's portion of the Percent of Premium shall equal 
IPA's cumulative share per employer group, based upon the number of men, 
women and children Subscribers of such employer group designating IPA as 
their Participating Medical Group for the month of Capitation Payment. The 
Capitation Payment shall be subject to retroactive adjustment by PacifiCare 
based upon subsequent eligibility determinations of Subscribers designating 
IPA as their Participating Medical Group. Such retroactive adjustments shall 
be made within one hundred eighty (180) days after the end of the month for 
which the applicable Capitation Payment applies. The methodology for 
determining IPA's Capitation Payment is more fully set forth in the 
PacifiCare Provider Policies and Procedures Manual in Attachment D hereto.

     PacifiCare shall provide IPA appropriate documentation in support of the
actual Capitation Payment made.  Should IPA desire additional billing
information; PacifiCare shall make available for inspection other mutually
agreed upon documents, upon thirty (30) days prior written notice from IPA. IPA
shall have the right to reasonably audit PacifiCare's books and records directly
relating only to IPA's Capitation Payment determinations upon thirty (30) days
prior written notice at IPA's sole expense.

     URGENT CARE (Not Applicable)

     If IPA elects to and qualifies under PacifiCare UCC criteria to participate
in the UCC program during the contract term, IPA must give PacifiCare sixty (60)
days written notice of intent to participate in UCC program.

     DME PAYMENT (Not Applicable)

     If IPA elects to provide DME during the contract term, IPA must give
PacifiCare sixty (60) days written notice of intent to provide DME.

     MATERNITY PAYMENTS

     For term pregnancies within nine (9) months of a Subscriber's initial
enrollment with PacifiCare or assignment to IPA, the following amount shall be
payable at the time of processing the inpatient obstetrical claim: [  **  ].

     MAMMOGRAPHY SERVICES

     IPA shall receive [  **  ] for each screening and diagnostic mammography 
study performed above the 1987 PacifiCare wide baseline, specific to the 
PacifiCare commercial program, for such studies. (This baseline equals 
[  **  ] studies per [  **  ] adult females per Year.)

The amount due to IPA shall be calculated based upon utilization date submitted
by IPA and shall be paid within one hundred fifty (150) days of the end of the
Year.

     1990 CAPITATION GUARANTEE

     For 1990, PacifiCare guarantees that IPA will receive a minimum increase 
in the average capitation paid to IPA, for the twelve month period, on the 
basis of the dollars received by IPA per Subscriber, using the same 
demographic and plan mix provided by PacifiCare during 1989. Such increase 
shall be guaranteed to be no less that [  **  ] average per member per month 
capitation payment for 1989.

     The comparison calculation performed by PacifiCare shall take into account
the net capitation paid (after Individual Stop Loss premiums are deducted). In
order to guarantee the effect of rate increases generated by the percent of
premium payment method, calculations will use the same demographic (male,
female, child) and plan (e.g. Preferred, Standard, 880) mix present during 1989.
Any applicable Urgent Care or Durable Medical Equipment payments shall not be
factored into the guarantee calculations.

     For the purposes of this calculation, the average 1989 capitation 
payment to IPA equalled [  **  ] per Subscriber per month and the 1990 
[  **  ] figure shall equal [  **  ] per Subscriber per month. Should the 
average 1990 capitation payment (calculated as described in the above 
paragraph), fall below the guaranteed amount, PacifiCare shall owe IPA a 
payment which represents the difference.  The payment amount shall be 
calculated by multiplying the difference, as stated on a per Subscriber per 
month basis, times the total number of member months for 1990. Should the 
average 1990 capitation payment equal or exceed the guaranteed dollar amount, 
no additional payment will be due IPA. IPA shall receive the 1990 guarantee 
calculation and any applicable payments no later than February 28, 1991.

                               PHARMACY CONTROL PROGRAM


     The purpose of the Pharmacy Control Program (PCP) is to provide an
incentive to the IPA to foster the efficient utilization of prescription
services. The PCP gives the IPA the ability to share in any savings when
comparing actual utilization against an established budget.

     The budget will be set at the following amounts on a per Subscriber per
month (pmpm) basis and will be calculated based on the mix of copay plans of
Subscribers who have designated IPA as their Participating Medical Group:

<TABLE>
<CAPTION>

     Plan Type              Budget Amount
     ---------              -------------

     $6 copay                  $[  **  ] 

</TABLE>

Debited against this budget will be the actual expenses paid by 
PacifiCare for pharmacy services of those Subscribers which designated IPA as 
their Participating Medical Group for the applicable month. The IPA will 
share [  **  ] of any savings in comparing the budget and actual expenses.   
PacifiCare shall provide, on a quarterly basis, utilization reports 
pertaining to the cost of prescriptions written on a physician specific 
basis. A final calculation and final payment will be made within one hundred 
fifty (150) days of the end of each Year.

     IPA agrees to participate in a generic drug substitution program and
formulary program established by PacifiCare's Quality Assurance Committee.

                                AIDS STOP LOSS PROGRAM

     PacifiCare agrees to provide additional financial protection to IPA for the
cost of Medical Services rendered to Subscribers who have AIDS. Subscribers who
are eligible for this program are as follows:

     Subscribers who are admitted to a hospital for the treatment of an
     opportunistic infection and have been diagnosed with clinical AIDS.

     Once PacifiCare's medical services department has verified that a
Subscriber meets the definition above, further expenses for Medical Services
associated with the Subscriber's AIDS care will be paid by PacifiCare as defined
by Cost of Care in Attachment A4 hereto. To receive reimbursement, IPA must
submit a stop loss claim to PacifiCare indicating the date the Subscriber became
eligible for the AIDS Stop Loss Program and the expenses incurred on behalf of
the Subscriber after the effective date. (IPA may include claims under the AIDS
Stop Loss Program commencing on the date the Subscriber was admitted to the
hospital, or on the date home health care was provided the Subscriber in-lieu of
hospitalization, pursuant to the eligibility criteria noted above.) Expenses for
Medical Services pertaining to AIDS care rendered from January 1, 1990 through
December 31, 1990 only will be included in the Aids Stop Loss Program. A final
claim must be filed for such Medical Services by March 31, 1991 to be included
in this AIDS Stop Loss Program.

     All claims submitted for consideration under the AIDS Stop Loss Program
must be processed and coordinated in a confidential manner. Inquiries for
determining such procedures should be directed to PacifiCare's medical director.

     The attached template outlines the division of financial responsibility
between IPA, Hospital and PacifiCare, the intent being to clarify Medical
Services and Medical Service categories in order to provide for accurate
administration. As it is impossible to include every Health Care Service
available, the template serves as a model under which broad Health Care Service
categories suggest the appropriate financial responsibility for Health Care
Services or items not specifically listed.

                                 AMENDMENT TO

                       IPA COMMERCIAL SERVICES AGREEMENT

The undersigned parties to the PacifiCare IPA Commercial Services Agreement 
("Agreement") between PacifiCare of California ("PacifiCare") and Santa Ana 
Tustin Physicians Group, Inc. ("IPA") do hereby amend the Agreement as set 
forth herein. Except as otherwise specifically provided, terms utilized 
herein shall have the meanings set forth in the Agreement. Except as 
specifically amended herein, the Agreement shall remain unchanged and in full 
effect.

1.   Paragraph 6.01, TERM, is amended in full to read as follows:
     
     6.01   TERM - The term of this Agreement shall be for thirty-six (36) 
     months and shall begin on January 1, 1996 (the "Commencement Date") and 
     end on December 31, 1998 ("Initial Term"). A "Year" under this Agreement 
     shall begin on January 1 and end on December 31. After the expiration of 
     the Initial Term, the Agreement shall be automatically extended for 
     one (1) year terms upon the expiration of the prior term unless either 
     party provides the other with written notice of such party's intention 
     not to extend the term no less than three hundred and sixty-five (365) 
     days prior to the end of the initial term or one hundred and eighty (180) 
     days prior to the end of each subsequent term thereafter or until this 
     Agreement is appropriately terminated by either party as provided in 
     Section 7 herein. Notwithstanding the above, should IPA breach the 
     covenant not to compete as stated in Paragraph 9.02 of the IPA Medicare 
     Shared Risk Services Agreement, this Agreement shall be automatically 
     extended for one (1) year terms on each successive January 1 upon the 
     expiration of the calendar year during which the breach occurs. In 
     addition, PacifiCare may terminate this Agreement by providing IPA at 
     least sixty (60) days prior written notice within ninety (90) days of 
     receiving notification of IPA's breach of the covenant not to compete 
     as stated in Paragraph 9.02 of the IPA Medicare Shared Risk Services 
     Agreement. For the Initial Term and any additional one-year terms, IPA 
     may continue to use any hospital, including but not limited to Tustin 
     Hospital, Western Medical Centers and Chapman General Hospital.

2.   Paragraph 12.07, ASSIGNMENT, is amended in full to read as follows:

     12.07  ASSIGNMENT - This Agreement and the rights, interests and 
     benefits hereunder shall not be assigned, transferred, pledged, or 
     hypothecated in any way by IPA or PacifiCare and shall not be subject 
     to execution, attachment or similar process, nor shall the duties 
     imposed herein be subcontracted or delegated without the written 
     consent of the other party.

     Notwithstanding, PacifiCare may assign, transfer, pledge or hypothecate 
     this Agreement and its rights, interests and benefits hereunder to any 
     entity of which PacifiCare has at least majority control.

The effective date of this Amendment is January 1, 1996.

3.   Paragraph 1, DEFINITIONS, is amended in part to add the following
     definitions:

          NET PREMIUM - is the amount of gross premiums billed by PacifiCare 
     each month for coverage of Subscribers designating IPA as their 
     Participating Medical Group, excluding amounts billed by PacifiCare to

<PAGE>

          PHARMACY PREMIUM - is the gross premiums billed by PacifiCare each
     month for coverage of Subscribers for the outpatient prescription drug
     benefit.

4.   Paragraph 3.07.01, COLLECTION OF CHARGES FOR OUT-OF-NETWORK SERVICES, is
     amended in full to read as follows:

     3.07.01 COLLECTION OF CHARGES FOR OUT-OF-NETWORK SERVICES - Notwithstanding
     anything to the contrary in Section 3.07 or elsewhere in the Agreement, if
     an IPA Member Physician or Specialist Physician provides Out-of-Network

     Out-of-Network Indemnity Plan carrier for such services and agrees to 
     accept full reimbursement at the Cost of Care rates described in 
     Attachment A4 of this Agreement.

5.   Paragraph 3.16, RECIPROCITY AGREEMENTS, is amended in full to read as
     follows:

     3.16      RECIPROCITY AGREEMENTS - IPA agrees to develop agreements among
     PacifiCare's Participating Medical Groups to assure reciprocity of health
     care among the Participating Medical Groups for PacifiCare Subscribers. IPA
     shall accept non-emergency or specialty Referrals from such other
     Participating Medical Groups and such other Participating Medical Groups
     shall be required to accept non-emergency or specialty Referrals from IPA.
     Payment for the foregoing Referrals shall be no greater than the Cost of
     Care Rates described in Attachment A4.

6.   Paragraph 5.04, MOST FAVORED PLAN is added to read as follows:

     5.04      MOST FAVORED PLAN - IPA represents that, during the term of this
     Agreement, the compensation rates payable under this Agreement are and
     shall continue to be equal to or less than the rates charged under other
     IPA agreements for the provision of services to enrollees of health care
     service plans ("Competing Plan Agreements"), when such rates are adjusted
     to reflect different risk levels and programs under the Competing Plan
     Agreements (the "Adjusted Rates"). If at any time IPA agrees or has agreed
     to accept lower Adjusted Rates under a Competing Plan Agreement than the
     rates set forth in this Agreement, or any amendment hereto, IPA shall
     immediately notify PacifiCare in writing of such agreement and the
     applicable lower Adjusted Rates.  Within thirty (30) days thereafter,
     PacifiCare and IPA shall meet to discuss implementation of new compensation
     rates under this Agreement which shall be equal to or less than the
     Adjusted Rates accepted under the Competing Plan Agreement. If the


                                        - 2 -
<PAGE>

     parties fail to agree to implementation procedures for the new 
     rates within thirty (30) days of the effective date of the Competing 
     Plan Agreement, the compensation rates under this Agreement will be 
     lowered upon notice to IPA from PacifiCare to equal the lower Adjusted 
     Rate. The new compensation rates shall be effective the date the lower 
     Adjusted Rates become effective under the Competing Plan Agreement. 
     IPA's failure to notify PacifiCare of the acceptance of lower Adjusted 
     Rates from a Competing Plan shall be grounds for termination of this 
     Agreement by PacifiCare pursuant to Section 7.01.02(d).

7.   Attachment A1, HOSPITAL SERVICES, is amended in part to read as follows:

     Paragraph 1.f. (Covered Inpatient Hospital Care) is added to read as

                          1995 UTILIZATION CONTROL PROGRAM

1.     INTRODUCTION

The Utilization Control Program is designed to provide a financial incentive for
the control of Hospital Services, in-area Emergency Services and selected other
services. The Utilization Control Program utilizes a Withhold Amount as defined
below.  Risk limitations are included at both the individual Subscriber claim
level, through the payment of a reinsurance premium for specific stop loss (the
deductible, premium and coinsurance rates are specified in the Budget below);
and at the aggregate level, through a percentage limitation on overall shared
savings or losses. Calculations are based on Budgets in effect for each month.

  a. WITHHOLD AMOUNT - PacifiCare shall withhold from IPA's monthly Capitation
  Payment an amount equal to [  **  ] to apply to IPA's share of Budget 
  Deficits, if any. PacifiCare may prospectively adjust the Withhold Amount on
  a quarterly basis based upon the results of Utilization Control Program 
  calculations. If the Agreement is terminated or non-renewed pursuant to 
  Section 6 or Section 7 of the Agreement, Pacificare may choose to adjust
  the Withhold Amount at the time that the notice of termination or 
  non-renewal is served.

2.     UTILIZATION CONTROL PROGRAM BUDGET ("Budget") shall equal the sum of A
       and B below:

       A.   For Hospital Services, [  **  ] and minus the applicable 
       reinsurance premium as set forth in Section 9 to this Attachment A5.

       B.   For Pharmacy Services, [  **  ] of the Pharmacy Premium
       per Subscriber per month, plus [  **  ] per member per
       month rebate for drugs ("Drug Rebate") ordered through Prescription
       Solutions during calendar year 1995. Notwithstanding Section 12.12,
       PacifiCare may amend the Drug Rebate on an annual basis effective each
       January 1 by providing sixty (60) days prior written notice to IPA.

3.     ACTUAL COSTS are defined for purposes of the Utilization Control Program
       as the sum of the following:


                                        - 6 -
<PAGE>

       a.   Hospital Services incurred during the period of calculation for
       which PacifiCare has received a claim and paid, valued at the amount
       paid by PacifiCare;

       b.   For quarterly interim calculations, Hospital Services incurred
       during the period of calculation for which PacifiCare has received a
       claim but has not paid, less an average aggregate discount factor (for
       year-end calculations, only paid claims will be included);

       c.   Hospital Services incurred prior to the period of calculation, and
       paid during the current period;

       d.   Prescription drug expenses arranged on behalf of Subscribers
       assigned to IPA.

       LESS:

       e.   Subscriber claim costs for Hospital Services in excess of the
       Reinsurance Deductible, as set forth in Section 9 to this Attachment A5.

       f.   Third party recoveries and coordination of benefits recoveries
       received during the period of calculation that are associated with
       current or prior calculation periods.

4.     BUDGET DEFICIT

If the Actual Costs exceed the Budget during any Year, the amount of this 
excess will be referred to as the Budget Deficit. IPA's share of the Budget
Deficit shall be [  **  ] of the Budget Deficit, but not to exceed [  **  ]
of the Budget. In the event of a Budget Deficit, PacifiCare shall pay IPA the
Withhold Amount, less IPA's share of the Budget Deficit. If IPA's share of 
the Budget Deficit is greater than the Withhold Amount for the Initial Term,
the difference between these amounts (the "Additional Payable Amount") shall
be payable by IPA to PacifiCare within thirty (30) days from receipt of the 
calculation.

5.     BUDGET SURPLUS

In the event that Actual Costs are less than the Budget for any year, this
shall be referred to as a Budget Surplus. In the event of a Budget Surplus,
PacifiCare shall pay IPA the Withhold Amount, plus the share of savings 
relative to the bed days per [  **  ] indicated in the following sliding
scale schedule:

</TABLE>

For the purpose of this calculation, "Bed Days; Outpt. Surgery" shall be 
defined as acute inpatient days plus outpatient surgeries, minus any acute 
inpatient days or outpatient surgeries which are covered under the 
reinsurance program, or are paid through a third party recovery, or through
coordination of benefits.

6.     PERIODIC CALCULATIONS

Cumulative calculations of the Utilization Control Program results will be 
based on calendar quarters. Interim calculations and payments will be made 
within sixty (60) days of the end of each calendar quarter except for the 
fourth quarter for which no calculation or payment will be made in 
anticipation of the final year end settlement. Calculations will be made in 
accordance with the contractual terms above and the amount of PacifiCare's 
quarterly payments to or from IPA will be sixty percent (60%) of the amount 
due in order to adjust for incurred Hospital Service claims not yet received
by PacifiCare.

A calendar year-end calculation of the Utilization Control Program shall be made
by PacifiCare and payment, if required, shall be made within one hundred twenty
(120) days of the end of the calendar year. If an additional amount is payable
by IPA to PacifiCare, such payment is due within thirty (30) days of receipt of
calculation.

7.     MONTHLY REPORTING

PacifiCare will distribute a report monthly, on or before the 15th day of the
month, that lists the payments made during the previous month for Hospital
Services included in the Utilization Control Program.

8.     Any hospital or emergency expenses that are considered third party
liability, workers compensation claims, or coordination of benefits claims,
shall be included in the Utilization Control Program calculations. If, at a
later date, these claims are collected from any third party, then an adjustment
will be made in the calculations.

9.     REINSURANCE.

The purpose of the reinsurance program described herein is to limit IPA's 
risk for Hospital Services under the Utilization Control Program to a 
specified amount per Subscriber per Year (the "Reinsurance Deductible") in 
return for a payment of a Reinsurance Premium. For the 1995 calendar year, 
the Reinsurance Deductible shall be [  **  ] and the Reinsurance Premium shall
equal [  **  ] of the Net Premium per Subscriber per month. Notwithstanding
Section 12.12, PacifiCare may amend the Reinsurance Premium and Reinsurance
Deductible on an annual basis effective each January l by providing sixty 
(60) days prior written notice to IPA.

                    PACIFICARE POINT OF SERVICE CONTROL PROGRAM


1.     INTRODUCTION

The PacifiCare Point of Service Control Program is designed to provide a 
financial incentive for the control of In-Network Hospital Services and 
Out-of-Network Services.

PacifiCare Point of Service Subscriber member months and related In-Network
Hospital Service expenses shall not be included in calculating the 
Conventional Utilization Control Program described in Attachment A5.

2.     POINT OF SERVICE BUDGET - shall equal [  **  ] of the Net Premiums 
billed, [  **  ] specified in Attachment A5, Paragraph 9 in this Agreement 
for the Reinsurance Deductible specified in Attachment A5, Paragraph 9 of 
this Agreement for In-Network Hospital Services reinsurance.

3.     ACTUAL COSTS applied against the Point of Service Budget will consist
of:

  a.   In-Network Hospital Services costs incurred during the period of
       calculation for which PacifiCare has received a claim and paid net of
       discounts; In-Network Hospital Services incurred prior to the period of
       calculation and paid during the current period; and for quarterly
       interim calculations, In-Network Hospital Services incurred during the
       period for which PacifiCare has received a claim but has not paid, less
       an average aggregate discount factor (for year end calculations, only
       paid claims will be included); LESS Subscriber claim costs in excess of
       the In-Network Hospital Services reinsurance deductible specified above;

  b.   Claims paid charges for Out-of-Network Services incurred during the
       current period; and paid claim charges for Out-of-Network Services
       incurred but not included in prior period Point of Service Control
       Program calculations; LESS

  c.   Third party liability and coordination of benefit recoveries for
       In-Network and Out-of-Network Services that are received during the
       period of calculation


                                        - 10 -
<PAGE>

3.     SAVINGS DISTRIBUTION - In the event that total charges are less than 
the earned Point of Service Budget, IPA shall be entitled to participate in a
capitation restoration program, whereby IPA shall receive the difference 
between actual capitation paid for PacifiCare Point of Service Subscribers 
for the period and the amount IPA would have received had IPA's capitation 
payments been based on [  **  ] of the rates as defined in Attachment C. 
Distribution to IPA under this capitation restoration program shall be 
limited to the savings available pursuant to the Point of Service Control 
Program calculation. Additionally, IPA shall receive [  **  ] of any remaining 
savings, if any, after the IPA capitation restoration distribution.

IPA is not at financial risk in the event that total charges exceed the earned
Point of Service Budget.

4.     PERIODIC CALCULATIONS - The PacifiCare Point of Service Control Program
shall be administered on an IPA specific basis. For IPAs with multiple IPA
Facilities, the program shall be calculated for each IPA Facility, however
savings and payment distributions shall be based on IPA's consolidated results.

Cumulative calculations of the PacifiCare Point of Service Control Program 
results will be based on calendar quarters in conjunction with Conventional 
Plan Hospital Control Program calculations, which are within sixty (60) days 
of the end of each calendar quarter except for the forth quarter for which no 
calculation or payment will be made in anticipation of the year end 
settlement. Interim distribution payments will be limited to sixty percent 
(60%) of calculated savings to account for incurred but not received claims.

Year end calculations and payments of the PacifiCare Point of Service Control
Program shall be made within one hundred twenty (120) days of the end of each
calendar year.

                              CAPITATION PAYMENT RATES

The monthly Capitation Payment which PacifiCare shall pay IPA shall equal 
IPA's cumulative shares of the Percent of Premium. The Percent of Premium 
designated by PacifiCare for payment for Medical Services shall equal
[  **  ] of the Net Premiums per Subscriber per month, minus the applicable 
ISL premium as identified in Attachment A3. IPA's portion of the Percent of 
Net Premium shall equal IPA's cumulative share per employer group based upon 
the number of men, women and children Subscribers of such employer group 
designating IPA as their Participating Medical Group for the month of 
Capitation Payment."

An Experience-Rated Plan is a non-federally qualified plan in which the 
employers' premium is partially deferred and/or adjusted to reflect the 
actual medical costs incurred by the employers' Subscribers. For 
Experience-Rated Plans, the percent of premium for Capitation Payment 
purposes shall be calculated as a percent of the Actuarial Experience Rate, 
rather than of gross premiums billed. The Actuarial Experience Rate is 
calculated by the same method used to determine the premium for federally 
qualified plans, except that trended claims/utilization data may be 
considered to determine expected medical costs, and PacifiCare's 
administrative retention may be adjusted to reflect actuarial risk taken by 
the employer instead of PacifiCare. The Actuarial Experience will also be 
higher than billed premiums where employer premiums are partially deferred.

IPA acknowledges that [  **  ] of the above gross Capitation Payment rate is 
designated as the value for providing the utilization data described in 
Paragraph 8.03. Should IPA fail to submit such data, which was reasonably 
within the control of IPA to submit, within ninety (90) days of the date of 
service, PacifiCare shall permanently withhold [  **  ] of the IPA's 
Capitation Payment rate for each month IPA fails to submit such data.  The 
Capitation Payment shall be subject to retroactive adjustment by PacifiCare 
based upon subsequent eligibility determinations of Subscribers designating 
IPA as their Participating Medical Group. Such retroactive adjustments shall 
be made within one hundred eighty (180) days after the end of the month for 
which the applicable Capitation Payment applies. The methodology for 
determining IPA's Capitation Payment is more fully set forth in the 
PacifiCare Provider Policies and Procedures Manual in Attachment D hereto.

PACIFICARE POINT OF SERVICE CAPITATION PAYMENTS

Capitation Payments for PacifiCare Point of Service Plan Subscribers will be 
determined in the same manner as for Conventional Plan Subscribers, except as 
provided in this paragraph. IPA's Capitation Payment for PacifiCare Point of 
Service Plan Subscribers shall equal the Percent of Premium specified in this 
Attachment C multiplied by [  **  ] of the Premium billed by PacifiCare each 
month for coverage of Subscribers designating IPA as their Participating 
Medical Group, less [  **  ] the ISL Premium Rate specified for the 
Individual Stop Loss Program noted in Attachment A3.

PacifiCare shall provide IPA appropriate documentation in support of the actual
Capitation Payment made. Should IPA desire additional billing information,
PacifiCare shall make available for inspection other mutually agreed upon
documents, upon thirty (30) days prior written notice from IPA. IPA shall have
the right to reasonably audit PacifiCare's books and records directly relating
only to IPA's Capitation Payment determinations upon thirty (30) days prior
written notice at IPA's sole expense.

URGENT CARE

In consideration of IPA's operation of an approved Urgent Care Center, 
PacifiCare shall pay to IPA an additional [  **  ] per member per month. It 
is understood that the Urgent Care Center meets approved criteria, as 
referenced in Attachment I, on an ongoing basis in order to qualify for this 
adjustment.

DURABLE MEDICAL EQUIPMENT (DME)

In consideration of IPA providing durable medical equipment pursuant to the 
PacifiCare Health Plan, PacifiCare shall pay IPA an additional [  **  ] per 
member per month. DME includes but is not limited to corrective appliances, 
artificial aids, and prosthetics.

MATERNITY PAYMENTS

For term pregnancies delivered within nine (9) months of a Subscriber's 
initial assignment to IPA, PacifiCare shall pay IPA [  **  ] at the time of 
processing the inpatient obstetrical claim.

MAMMOGRAPHY SERVICES

IPA shall receive [  **  ] for each screening and diagnostic mammography 
study performed above the 1987 PacifiCare wide baseline, specific to the 
PacifiCare commercial program, for

                                        - 13 -
<PAGE>

such studies. (This baseline equals [  **  ] studies per [  **  ] adult 
females per Year.)

The amount due to IPA shall be calculated based upon utilization date submitted
by IPA and shall be paid within one hundred fifty (150) days of the end of the
Year. Such utilization data must be received by PacifiCare within ninety (90)
days of calendar year end to be included in this reimbursement program.

                                AIDS STOP LOSS PROGRAM


PacifiCare agrees to provide additional financial protection to IPA for the cost
of Medical Services rendered to Subscribers who have "Acquired Immunodeficiency
Syndrome" (AIDS).  Subscribers who are eligible for this program are as follows:

     Subscribers who are admitted to a hospital or referred to home health care
     for the treatment of an opportunistic infection and have been diagnosed
     with clinical AIDS according to the current Case Definition of AIDS used by
     the Center for Disease Control (CDC) for National Reporting (CDC-reportable
     AIDS).

Once PacifiCare's Medical Services Department has verified that a Subscriber
meets the definition above, further expenses for Medical Services associated
with the Subscriber's AIDS care will be paid by PacifiCare as defined by Cost of
Care in Attachment A4 hereto.  THE CONDITION FOR WHICH TREATMENT IS RENDERED
MUST BE DIRECTLY RELATED TO AIDS.  EXPERIMENTAL TREATMENT IS NOT COVERED.  To
receive reimbursement, IPA must submit a Stop Loss claim to PacifiCare
indicating the date the Subscriber became eligible for the AIDS Stop Loss
Program and the expenses incurred on behalf of the Subscriber after the
effective date.  IPA may include claims under the AIDS Stop Loss Program
commencing on the date the Subscriber was admitted to the hospital, or on the
date home health care was provided the Subscriber, pursuant to the eligibility
criteria noted above.  Expenses for Medical Services pertaining to AIDS care
rendered from January 1, through December 31 of each calendar year, will be
included in the AIDS Stop Loss Program.  A final claim must be filed for such
Medical Services by each March 31 to be included in this AIDS Stop Loss Program.

All claims submitted for consideration under the AIDS Stop Loss Program must be
processed and coordinated in a confidential manner.  Inquiries for determining
such procedures should be directed to PacifiCare's Medical Director.

                          IPA COMMERCIAL SERVICES AGREEMENT


The undersigned parties to the PacifiCare IPA Commercial Services Agreement
between PacifiCare of California ("PacifiCare") and Santa Ana-Tustin Physicians
Group, Inc.  ("IPA") do hereby amend said Agreement as follows:

1.   Section 3.29, WITHDRAWAL OF A MEMBER PHYSICIAN, shall be added as follows:

     "3.29     WITHDRAWAL OF A MEMBER PHYSICIAN - In the event IPA seeks to
withdraw one or more of the Member Physicians from providing or arranging Health
Care Services to Subscribers under this Agreement, IPA must notify PacifiCare of
such withdrawal in writing at least sixty (60) days prior to the effective
withdrawal date.  After the effective date of withdrawal, IPA shall still be
responsible to provide or arrange for Medical Services to such Subscribers."

2.   Attachment A5, HOSPITAL CONTROL PROGRAM, is amended as follows:

     See Exhibit 1, attached hereto and incorporated herein by this reference.

3.   Attachment C, CAPITATION PAYMENT RATES, shall be amended as follows:

The first paragraph shall be amended as follows:      "The monthly Capitation 
Payment which PacifiCare shall pay IPA shall equal IPA's cumulative shares of 
the Percent of Premium.  The Percent of Premium designated by PacifiCare for 
payment for Medical Services shall equal [  **  ] of the gross premiums 
billed by PacifiCare each month for coverage of Subscribers designating IPA 
as their Participating Medical Group pursuant to the PacifiCare Health Plan, 
not including the Supplemental Benefit Premiums less [  **  ] in 
consideration of the Individual Stop Loss Program noted in Attachment A3 
hereto, and also less necessary consideration as determined by PacifiCare for 
supplemental benefits for which IPA assumes no financial responsibility.  In 
instances where billed premiums reflect an additional charge to account for 
broker's fees that exceed PacifiCare's standard broker commission schedule 
("Broker Fee Adjustment"), such Broker Fee Adjustment shall not be included 
in the calculation of the IPA's Monthly Capitation Payment.  IPA's portion of 
the Percent of Premium shall equal IPA's cumulative share per employer group, 
based upon the number of men, women and children Subscribers of such employer 
group designating IPA as their Participating Medical Group for the month of 
Capitation Payment."

                                          1
<PAGE>

A second paragraph shall be inserted in Attachment C as follows: "An 
Experience-Rated Plan is a non-federally qualified plan in which the 
employers' premium is partially deferred and/or adjusted to reflect the 
actual medical costs incurred by the employers' Subscribers.  For 
Experience-Rated Plans, the percent of premium for Capitation Payment 
purposes shall be calculated as a percent of the Actuarial Experience Rate, 
rather than of gross premiums billed. The Actuarial Experience Rate is 
calculated by the same method used to determine the premium for federally 
qualified plans, except that trended claims/utilization data may be 
considered to determine expected medical costs, and PacifiCare's 
administrative retention may be adjusted to reflect actuarial risk taken by 
the employer instead of PacifiCare.  The Actuarial Experience will also be 
higher than billed premiums where employer premiums are partially deferred."

4.   Attachment E, PHARMACY CONTROL PROGRAM, is amended in full as follows:

     See Exhibit 2, attached hereto and incorporated herein by this reference.

5.   Attachment F, AIDS STOP LOSS PROGRAM, is amended in full as follows:

     See Exhibit 3, attached hereto and incorporated herein by this reference.

                           1994 - HOSPITAL CONTROL PROGRAM

1.   INTRODUCTION

The Hospital Control Program is designed to provide a financial incentive for
the control of Hospital Services, in-area Emergency Services and selected other
outpatient services.  The Hospital Control Program utilizes a Withhold Amount as
defined below.  Risk limitations are included at both the individual Subscriber
claim level, through the payment of a reinsurance premium for specific stop loss
(the deductible, premium and coinsurance rates are specified in the Budget
below); and at the aggregate level, through a percentage limitation on overall
shared savings or losses.  HCP calculations are based on Budgets in effect for
each month.

     a.   WITHHOLD AMOUNT - PacifiCare shall withhold from IPA's monthly
     Capitation Payment an amount equal to [  **  ] to apply to IPA's share
     of Budget Deficits, if any.  PacifiCare may prospectively adjust the
     Withhold Amount on a quarterly basis based upon the results of Hospital
     Control Program calculations.  If the Agreement is terminated or 
     non-renewed pursuant to Section 6 or Section 7 of the Agreement, 
     PacifiCare may choose to adjust the Withhold Amount at the time that 
     the notice of termination or non-renewal is served.

The Total Budget per Subscriber per month ("PMPM") to be used for settlement
purposes shall be calculated by applying the IPA's specific composite age/sex
factor to the budgeted amounts for Inpatient Hospital, Emergency Room and
Ambulance Services, Outpatient Surgery Services, and Selected Outpatient
Services.  The composite age/sex factor will be calculated by multiplying the
IPA's member months within each age/sex category listed below and dividing the
sum of these numbers by IPA's total member months.  The age/sex adjusted dollar
figure will be added to the other Hospital Control Program budget components.

3.   ACTUAL COSTS
     Actual costs are defined for purposes of the Hospital Control Program as
the sum of the following:

          a.   Hospital Services incurred during the period of calculation for
          which PacifiCare has received a claim and paid, valued at the amount
          paid by PacifiCare;

          b.   For quarterly interim calculations, Hospital Services incurred
          during the period of calculation for which PacifiCare has received a
          claim but has not paid, less an average aggregate discount factor (for
          year-end calculations, only paid claims will be included);

          c.   Hospital Services incurred prior to the period of calculation,
          and paid during the current period;

          LESS:
          d.   Subscriber claim costs in excess of the reinsurance deductible
          and coinsurance specified in the Budget;

          e.   Third party recoveries and coordination of benefits
          recoveries received during the period of calculation that are
          associated with current or prior calculation periods.

4.   CALCULATION OF SAVINGS AND LOSSES

The inpatient hospital component of the budget is stated assuming [  **  ] of 
Subscribers enroll in benefit plans with hospital service copayments, 
coinsurance and deductible obligations ("Co-Pay Plans").  It is also assumed 
that [  **  ] of Subscribers enroll in non-Co-Pay Plans ("Regular Plans").  
The Budget will be adjusted to reflect the actual number of Subscribers who 
enroll in the Co-Pay Plans and Regular Plans based upon PacifiCare's Member 
Month Moving Analysis Report for the period (MB0530).  The MB0530 Report is a 
report that reflects actual eligible Subscribers by benefit plan for the 
period, as adjusted for retroactive eligibility terminations and additions 
reported during the period as of the report's run date.  The Budget, when 
adjusted as described above, shall be referred to as the Earned Budget. The 
Earned Budget may be greater or less than the Total Budget PMPM indicated in 
Section 2 above.

5.   BUDGET DEFICIT

If the Actual Costs exceed the Earned Budget during any Year, the amount of 
this excess will be referred to as the Budget Deficit.  IPA's share of the 
Budget Deficit shall be [  **  ] of the Budget Deficit, [  **  ] of the 
Earned Budget.  In the event of a Budget Deficit, PacifiCare shall pay IPA 
the Withhold Amount, less IPA's share of the Budget Deficit.  If IPA's share 
of the Budget Deficit is greater than the Withhold Amount for the Initial 
Term, the difference between these amounts (the "Additional Payable Amount") 
shall be payable by IPA to PacifiCare within thirty (30) days from receipt of 
the calculation.

6.   BUDGET SURPLUS

In the event that Actual Costs are less than the Earned Budget for any year,
this shall be referred to as a Budget Surplus.  In the event of a Budget
Surplus, PacifiCare shall pay IPA the Withhold Amount, plus the share of savings
relative to the bed days per thousand Subscribers per year (PTMPY) indicated in
the following sliding scale schedule:

For the purpose of this calculation, "Bed Days; Outpt. Surgery" shall be
defined as acute inpatient days plus outpatient surgeries, minus any acute
inpatient days or outpatient surgeries which are covered under the reinsurance
program, or are paid through a third party recovery, or through coordination of
benefits.

7.   PERIODIC CALCULATIONS
Cumulative calculations of the Hospital Control Program results will be based on
calendar quarters.  Interim calculations and payments will be made within sixty
(60) days of the end of each calendar quarter except for the fourth quarter for
which no calculation or payment will be made in anticipation of the final year
end settlement.  Calculations will be made in accordance with the contractual
terms above and the amount of PacifiCare's quarterly payments to or from IPA
will be sixty percent (60%) of the amount due in order to adjust for incurred
Hospital Service claims not yet received by PacifiCare.

A calendar year-end calculation of the Hospital Control Program shall be made by
PacifiCare and payment, if required, shall be made within one hundred twenty
(120) days of the end of the calendar year.  If an additional amount is payable
by IPA to PacifiCare, such payment is due within thirty (30) days of receipt of
calculation.

8.   MONTHLY REPORTING
PacifiCare will distribute a report monthly, on or before the 15th day of the
month, that lists the payments made during the previous month for services
included in the Hospital Control Program.

9.   SPECIAL CONDITIONS FOR EMERGENCY SERVICES
If the IPA and/or its participating physicians direct a PacifiCare Subscriber to
use the emergency room of a hospital, and PacifiCare determines that the use of
those services were not Emergency Services as defined in this Agreement,
PacifiCare reserves the right to deduct the emergency room professional
component from the IPA's Capitation Payment as a penalty for improper referral.
When an inappropriate referral for emergency care has been determined by
PacifiCare, a written Conformance Request will be forwarded to the IPA.  The
Conformance Request will serve as notice that all subsequent inappropriate
referrals will have the penalty applied.

10.  Any hospital or emergency expenses that are considered third party
liability, workers compensation claims, or coordination of benefits claims,
shall be included in the Hospital Control Program calculations.  If, at a later
date, these claims are collected from any third party, then an adjustment will
be made in the calculations.

                            1994 PHARMACY CONTROL PROGRAM

The purpose of the Pharmacy Control Program (PCP) is to provide incentive to the
IPA to foster the efficient utilization of prescription services.  IF PHARMACY
COSTS PMPM FOR 1994 ARE AT OR BELOW THE IPA'S "AGE, SEX AND COPAYMENT ADJUSTED"
BUDGET, the IPA is given the opportunity to share in savings realized by IPA
maintaining or improving specific utilization goals as outlined below.

TOTAL BUDGET PMPM - The actual budget to be used for settlement purposes will be
calculated by applying the age/sex factor for each Subscriber to the budgeted
Copay Plan for each subscriber.  The total budget will be based on the mix of
age, sex, and copayment plans of Subscribers who have designated IPA as their
Participating Medical Group:

                             1994 AIDS STOP LOSS PROGRAM


PacifiCare agrees to provide additional financial protection to IPA for the cost
of Medical Services rendered to Subscribers who have "Acquired Immunodeficiency
Syndrome" (AIDS).  Subscribers who are eligible for this program are as follows:

     Subscribers who are admitted to a hospital or referred to home health care
     for the treatment of an opportunistic infection and have been diagnosed
     with clinical AIDS according to the current Case Definition of AIDS used by
     the Center for Disease Control (CDC) for National Reporting (CDC-reportable
     AIDS).

Once PacifiCare's Medical Services Department has verified that a Subscriber
meets the definition above, further expenses for Medical Services associated
with the Subscriber's AIDS care will be paid by PacifiCare as defined by Cost of
Care in Attachment A4 hereto.  THE CONDITION FOR WHICH TREATMENT IS RENDERED
MUST BE DIRECTLY RELATED TO AIDS.  EXPERIMENTAL TREATMENT IS NOT COVERED.  To
receive reimbursement, IPA must submit a Stop Loss claim to PacifiCare
indicating the date the Subscriber became eligible for the AIDS Stop Loss
Program and the expenses incurred on behalf of the Subscriber after the
effective date.  IPA may include claims under the AIDS Stop Loss Program
commencing on the date the Subscriber was admitted to the hospital, or on the
date home health care was provided the Subscriber, pursuant to the eligibility
criteria noted above.  Expenses for Medical Services pertaining to AIDS care
rendered from January 1, 1994 through December 31, 1994 only will be included in
the AIDS Stop Loss Program.  A final claim must be filed for such Medical
Services by March 31, 1995 to be included in this AIDS Stop Loss Program.

All claims submitted for consideration under the AIDS Stop Loss Program must be
processed and coordinated in a confidential manner.  Inquiries for determining
such procedures should be directed to PacifiCare's Medical Director.

                         DIVISION OF FINANCIAL RESPONSIBILITY

     The attached template outlines the division of financial responsibility
between IPA, the Hospital Control Program (HCP), and PacifiCare (PC), the intent
being to clarify Medical Service and Hospital Service categories in order to
provide for accurate administration.  As it is impossible to include every
service available, the template serves as a model under which broad Medical
Service and Hospital Service categories suggest the appropriate financial
responsibility for services or items not specifically listed.

4.   CALCULATION OF SAVINGS AND LOSSES

The inpatient hospital component of the budget is stated assuming [  **  ]of 
Subscribers enroll in benefit plans with hospital copayment/coinsurance/
deductible obligations for inpatient services ("Co-Pay Plans").  It is also 
assumed that [  **  ] of Subscribers enroll in non-Co-Pay Plans ("Regular 
Plans").  The earned budget will be adjusted to reflect the actual number of 
Subscribers who enroll in the Co-Pay Plans and Regular Plans based upon 
PacifiCare's Member Month Moving Analysis Report for the period (MB0530).  
The MB0530 Report is a report that reflects actual eligible Subscribers by 
benefit plan for the period, as adjusted for retroactive eligibility 
terminations and additions reported during the period as of the report's run 
date.  Therefore, the actual earned budget may be greater or less than the 
net budget indicated in this Attachment A-5.

                             1993 AIDS STOP LOSS PROGRAM

PacifiCare agrees to provide additional financial protection to IPA for the cost
of Medical Services rendered to Subscribers who have AIDS.  Subscribers who are
eligible for this program are as follows:

     Subscribers who are admitted to a hospital or referred to home health care
     for the treatment of an opportunistic infection and have been diagnosed
     with clinical AIDS.

Once PacifiCare's Medical Services Department has verified that a Subscriber
meets the definition above, further expenses for Medical Services associated
with the Subscriber's AIDS care will be paid by PacifiCare as defined by Cost of
Care in Attachment A4 hereto.  To receive reimbursement, IPA must submit a Stop
Loss claim to PacifiCare indicating the date the Subscriber became eligible for
the AIDS Stop Loss Program and the expenses incurred on behalf of the Subscriber
after the effective date.  IPA may include claims under the AIDS Stop Loss
Program commencing on the date the Subscriber was admitted to the hospital, or
on the date home health care was provided the Subscriber, pursuant to the
eligibility criteria noted above.  Expenses for Medical Services pertaining to
AIDS care rendered from January 1, 1993 through December 31, 1993 only will be
included in the AIDS Stop Loss Program.  A final claim must be filed for such
Medical Services by March 31, 1994 to be included in this AIDS Stop Loss
Program.

All claims submitted for consideration under the AIDS Stop Loss Program must be
processed and coordinated in a confidential manner.  Inquiries for determining
such procedures should be directed to PacifiCare's Medical Director.

4.        CALCULATION OF SAVINGS AND LOSSES

The inpatient hospital component of the budget is stated assuming [  **  ] of 
Subscribers enroll in benefit plans with hospital copayment/coinsurance/
deductible obligations for inpatient services ("Co-Pay Plans"). It is also 
assumed that [  **  ] of Subscribers enroll in non-Co-Pay Plans ("Regular 
Plans"). The earned budget will be adjusted to reflect the actual number of 
Subscribers who enroll in the Co-Pay Plans and Regular Plans based upon 
PacifiCare's Member Month Moving Analysis Report for the period (MB0530). The 
MB0530 Report is a report that reflects actual eligible Subscribers by 
benefit plan for the period, as adjusted for retroactive eligibility 
terminations and additions reported during the period as of the report's run 
date. Therefore, the actual earned budget may be greater or less than the net 
budget indicated in this Attachment A-5.

PacifiCare agrees to provide additional financial protection to IPA for the cost
of Medical Services rendered to Subscribers who have AIDS. Subscribers who are
eligible for this program are as follows:

     Subscribers who are admitted to a hospital or referred to home health care
     for the treatment of an opportunistic infection and have been diagnosed
     with clinical AIDS.

Once PacifiCare's Medical Services Department has verified that a Subscriber
meets the definition above, further expenses for Medical Services associated
with the Subscriber's AIDS care will be paid by PacifiCare as defined by Cost of
Care in Attachment A4 hereto. To receive reimbursement, IPA must submit a Stop
Loss claim to PacifiCare indicating the date the Subscriber became eligible for
the AIDS Stop Loss Program and the expenses incurred on behalf of the Subscriber
after the effective date. IPA may include claims under the AIDS Stop Loss
Program commencing on the date the Subscriber was admitted to the hospital, or
on the date home health care was provided the Subscriber, pursuant to the
eligibility criteria noted above. Expenses for Medical Services pertaining to
AIDS care rendered from January 1, 1993 through December 31, 1993 only will be
included in the AIDS Stop Loss Program. A final claim must be filed for such
Medical Services by March 31, 1994 to be included in this AIDS Stop Loss
Program.

All claims submitted for consideration under the AIDS Stop Loss Program must be
processed and coordinated in a confidential manner. Inquiries for determining
such procedures should be directed to PacifiCare's Medical Director.

     My signature below represents my acknowledgment and recognition that the
services I am requesting from (DOCTOR'S NAME) are not covered by under my
PacifiCare Health Plan. The requested services are not covered because (1) the
services are not emergency services and they have not been authorized by my
participating medical group physician or (2) the services are specifically
excluded under my PacifiCare Health Plan.

I further understand that if coverage for the requested services is available
under my Out-of-Network supplemental coverage, this coverage may be subject to
substantial deductibles and copayments.

                          PACIFICARE CHOICE CONTROL PROGRAM

The PacifiCare Choice Control Program is designed to provide a financial
incentive for the control of In-Network Hospital Services and Out-of-Network
Services.

PacifiCare Choice Subscriber member months and related In-Network Hospital
Service expenses shall not be included in calculating the Conventional Hospital
Control Program described in Attachment A5.

CHOICE BUDGET

THE CHOICE BUDGET - The Choice Budget shall consist of two components: When a 
Conventional Plan is sold in conjunction with the PacifiCare Choice Plan, the 
Choice Budget for such PacifiCare Choice Subscribers shall be established as 
[  **  ]; when a Conventional Plan is NOT sold in conjunction with the 
PacifiCare Choice Plan, the Choice Budget for such PacifiCare Choice 
Subscribers shall be established as [  **  ]. The Choice Budget assumes the 
PacifiCare Choice Plan sold requires a deductible no greater than [  **  ], a 
[  **  ] coinsurance for all Out-of-Network services, and In-Network Hospital 
Services do not require Subscriber copayments (i.e. 880, 1500 plans). IPA'S 
EARNED CHOICE BUDGET will be determined by adjusting each of the above two 
budget components to reflect the Choice Budget values for the actual plan mix 
of Pacificare Choice Subscribers assigned to IPA, and calculating the average 
in accordance the following table:

PERIODIC CALCULATIONS

The PacifiCare Choice Control Program shall be administered on an IPA specific
basis. For IPAs with multiple IPA Facilities, the program shall be calculated
for each IPA Facility, however savings and payment distributions shall be based
on IPA's consolidated results.

Cumulative calculations of the PacifiCare Choice Control Program results will be
based on calendar quarters in conjunction with Conventional Plan Hospital
Control Program calculations, which are within sixty (60) days of the end of
each calendar quarter except for the fourth quarter for which no calculation or
payment will be made in anticipation of the year end settlement. Interim
distribution payments will be limited to sixty percent (60%) of calculated
savings to account for incurred but not received claims.

Year end calculations and payments of the PacifiCare Choice Control Program
shall be made within one hundred fifty (150) days of the end of each calendar
year.

1. INTRODUCTION

The Hospital Control Program is designed to provide a financial incentive for 
the control of inpatient, in-area Emergency Services and selected other 
outpatient services. When actual incurred costs, when compared to a 
predetermined budget, are favorable, the savings are shared with the IPA. 
Conversely, when actual incurred costs exceed the budget, the IPA shares the 
additional costs. Risk limitations are included at both the individual 
Subscriber claim level (through the payment of a reinsurance premium for 
specific stop loss) and at the aggregate level (through a percentage 
limitation on overall shared savings or losses) to mitigate extraordinary 
performance fluctuations.

The total budget PMPM to be used for settlement purposes shall be calculated by
applying the IPA's specific composite age/sex factor to the budgeted amounts for
Inpatient Hospital, Emergency and Ambulance Services, Outpatient Surgery
Services, and Selected Outpatient Services. The composite age/sex factor will be
calculated by multiplying the IPA's member months within each age/sex category
listed below and dividing the sum of these numbers by IPA's total member months.
The age/sex adjusted dollar figure will be added to the other Hospital Control
Program budget components.

3.   ACTUAL COSTS

     Actual costs are defined for purposes of this Program as:

          a.   Hospital Services incurred during the period of calculation for
          which PaciflCare has received a claim and paid net of discounts,

          b.   For quarterly interim calculations, Hospital Services incurred
          during the period of calculation for which PacifiCare has received a
          claim but has not paid, less an average aggregate discount factor (for
          year end calculations only paid claims will be included),

          c.   Hospital Services incurred prior to the period of calculation,
          and paid during the current period,

          LESS;

          d.   Subscriber claim costs in excess of the reinsurance deductible
          specified in the budget above,

          e.   Third party recoveries received during the period of calculation
          that are associated with current or prior period calculation periods.


                                          7
<PAGE>

4.   CALCULATION OF SAVINGS AND LOSSES

The inpatient hospital component of the budget is stated assuming [  **  ] of 
the Subscribers enrolled in the 880 Plan and [  **  ] of the Subscribers in 
all other plans. The earned budget will be adjusted to reflect the actual 
number of Subscribers who enrolled in the 880 and non-880 plans based upon 
PacifiCare's Member Month Moving Analysis Report for the period (MB0530). The 
MB0530 Report is a report that reflects actual eligible Subscribers by 
benefit plan for the period as adjusted for retroactive eligibility 
terminations and additions reported during the period as of the report's run 
date. Therefore, the actual earned budget may be greater or less than the net 
budget indicated in this Attachment.

5.   DISTRIBUTION OF SAVINGS - In the event that actual costs are less than 
the earned budget, then the IPA shall receive the share of savings relative 
to the bed days per thousand Subscribers per year (PTMPY) indicated in the 
following sliding scale schedule:

<TABLE>
<CAPTION>

- -----------------------                 --------------------------------
<S>                                     <C>

[  **  ]                                            [  **  ]

[  **  ]                                            [  **  ]
</TABLE>

For the purpose of this calculation, "Bed Days/Outpt. Surgery" shall be defined
as acute inpatient days plus outpatient surgeries, net of any acute inpatient
days or outpatient surgeries which are covered under the reinsurance program, or
are paid through a third party recovery, or through coordination of benefits.

6.   DISTRIBUTION OF DEFICIT - If actual costs are greater than the earned 
budget, then the IPA will be liable for [  **  ] of the amount lost up to the 
maximum payment specified below;

               MAXIMUM DEFICIT PAYMENT: [  **  ]

7.   PERIODIC CALCULATIONS - Cumulative calculations of the Hospital Control
Program results will be based on calendar quarters. Interim calculations and
payments will be made within sixty (60) days of the end of each calendar quarter
except for the fourth quarter for which no calculation or payment will be made
in anticipation of the final year end settlement. Calculations will


                                          8
<PAGE>

be made in accordance with the contractual terms above and the amount of
PacifiCare's quarterly payments to IPA will be sixty percent (60%) of the amount
due in order to adjust for incurred Hospital Service claims not yet received by
PacifiCare.

In the event that the interim calculation reflects a cumulative loss for the
IPA, no interim payment will be due from IPA in the first quarter that a loss
results. However, if a cumulative loss is reflected for two consecutive
quarters, the IPA will make an interim payment of sixty percent (60%) of the
cumulative amount due to PacifiCare. Such payment to PacifiCare shall be due
within fifteen (15) days of the IPA's receipt of such notice from PacifiCare.

A calendar year-end calculation of the Hospital Control Program shall be made by
PacifiCare and payment to the appropriate party shall be made within one hundred
twenty (120) days of the end of the calendar year.

8.   MONTHLY REPORTING - PacifiCare will distribute a report monthly , on or
before the 15th, that lists the payments made during the previous month for
services included in the Hospital Control Program.

9.   SPECIAL CONDITIONS FOR EMERGENCY SERVICES - If the IPA and/or its
participating physicians direct a PacifiCare Subscriber to use the
emergency room of a hospital, and PacifiCare determines that the use of those
services were not Emergency Services as defined in this Agreement, PacifiCare
reserves the right to deduct the professional component of the PacifiCare
payment from the IPA's capitation as a penalty for improper referral. When an
inappropriate referral for emergency care has been determined by PacifiCare, a
written Conformance Request will be forwarded to the IPA. The Conformance
Request will serve as notice that all subsequent inappropriate referrals will
have the penalty applied.

10.  Any hospital or emergency expenses that are considered third party
liability, Workers Compensation claim, or coordination of benefits claims, shall
be included in the calculations. If, at a later date, these claims are collected
then an adjustment will be made in the calculations.

11.  Calculations shall not include hospital admissions which are not authorized
by IPA and which are not Emergency Services.

                               AIDS STOP LOSS PROGRAM

PacifiCare agrees to provide additional financial protection to IPA for the cost
of Medical Services rendered to Subscribers who have AIDS. Subscribers who are

     Subscribers who are admitted to a hospital for the treatment of an
     opportunistic infection and have been diagnosed with clinical AIDS.

Once PacifiCare's Medical Services Department has verified that a Subscriber
meets the definition above, further expenses for Medical Services associated
with the Subscriber's AIDS care will be paid by PacifiCare as defined by Cost of
Care in Attachment A4 hereto. To receive reimbursement, IPA must submit a Stop
Loss claim to PacifiCare indicating the date the Subscriber became eligible for
the AIDS Stop Loss Program and the expenses incurred on behalf of the Subscriber
after the effective date. IPA may include claims under the AIDS Stop Loss
Program commencing on the date the Subscriber was admitted to the hospital, or
on the date home health care was provided the Subscriber in-lieu of
hospitalization, pursuant to the eligibility criteria noted above. Expense for
Medical Service pertaining to AIDS care rendered from January 1 1992, through
December 31, 1992 only will be included in the AIDS Stop Loss Program. A final
claim must be filed for such Medical Services by March 31, 1993 to be included
in this AIDS Stop Loss Program.

All claims submitted for consideration under the AIDS Stop Loss Program must be
processed and coordinated in a confidential manner. Inquiries for determining
such procedures should be directed to PacifiCare's Medical Director.

                           PHARMACY CONTROL PROGRAM

     The purpose of the Pharmacy Control Program (PCP) is to provide an 
incentive to the IPA to foster the efficient utilization of prescription 
services. The IPA is given the opportunity to share in [  **  ] of any savings 
when per member per month expenses are compared to budget, with a limited 
amount of commensurate downside risk.

I. BUDGET

The budget will be set at the following amounts on a per Subscriber per month 
(pmpm) basis and will be calculated based on the mix of copay plans of 
Subscribers who have designated IPA as their Participating Medical Group:

<TABLE>
<CAPTION>

           Plan Type          Budget Amount
           ---------          -------------

           $4 copay              [  **  ]
           $5 copay              [  **  ]
           $6 copay              [  **  ]
           $7 copay              [  **  ]

</TABLE>

Debited against this budget will be the actual expenses paid by PacifiCare 
for pharmacy services of those Subscribers which designated IPA as their 
Participating Medical Group for the applicable month.

II. RISK SHARING FORMULA

The IPA will share [  **  ] of any savings in comparing the budget 
and actual expenses.

The IPA will be responsible for [  **  ] of any dollar amounts 
more than [  **  ] over the composite per member per month budget 
figure.

PacifiCare shall provide, on a quarterly basis, utilization reports 
pertaining to the cost of prescriptions written on a physician specific basis 
and a year-to-date comparison of performance to budget. A final calculation 
and final payment will be made within one hundred fifty (150) days of the end 
of each year.

IPA agrees to participate in a generic drug substitution program and 
formulary program established by PacifiCare's Quality Assurance Committee.

financially responsible for all Medical Services specified in Attachment A2,
incorporated in full herein by reference, provided to Subscribers for whom IPA
is to receive monthly Capitation Payment from PacifiCare based upon the
PacifiCare provided Eligibility List. IPA shall be responsible for determining
whether Subscribers are eligible for Medical Services on the basis of the most
current Eligibility List supplied to IPA by PacifiCare. Updated eligibility
information shall be available from PacifiCare as needed on the basis of the
most current information supplied PacifiCare by HCPA.

     3.02 STANDARDS - All Medical Services arranged for or provided by IPA 
and its Member Physicians shall be provided by professional personnel and at 
physical facilities according to generally accepted standards of medical

arrange for Referrals to Specialist Physicians and facilities as are 
necessary, appropriate, and in accordance with generally accepted standards 
of medical practice in the community in compliance with the standards 
developed by PacifiCare's Quality Assurance Committee. If IPA contracts with 
Specialist Physicians to provide Medical Services under this Agreement, IPA 
shall require such Specialist Physicians to provide IPA with the 
credentialing information set forth herein. IPA shall obtain and maintain 
information concerning each Member Physician's and Specialist Physician's 
education, training, references, malpractice liability insurance, hospital 
staff status, hospital clinical privileges, and hospital staff reappointment 
dates. Such information shall be kept in a form prescribed by or acceptable 
to PacifiCare. Upon request, the credentialing information shall be made 
available to PacifiCare for review or copying.

     IPA acknowledges and agrees that it shall report Member Physicians or
Specialist Physicians as required by the California Business and Professions
Code Section 805 ("Section 805"). IPA further agrees to maintain and demonstrate
to PacifiCare upon request compliance with the following:

               3.02.01   IPA shall insure that its Member Physicians and 
Specialist Physicians are licensed by the State of California and have

notify PacifiCare in writing of any of the following actions taken by or 
against a Member Physician or Specialist Physician: (i) the surrendering, 
revocation, or suspension of a license; (ii) the surrendering, revocations, 
or suspension of current DEA registration; (iii) any filing pursuant

                                          7
<PAGE>

to Section 805; (iv) any filing pursuant to the National Practitioner Data 
Bank; (v) the filing of any malpractice claim of more than ten thousand 
dollars ($10,000); and (vi) a change in hospital staff status or hospital 
clinical privileges, including any restrictions or limitations.

               If IPA fails to obtain and maintain the information set forth in
Paragraph 3.02 or fails to immediately notify PacifiCare as set forth in this
Paragraph 3.02.01, IPA shall indemnify and hold harmless PacifiCare from and
against any claim, loss, damage, cost, expense or liability arising out of or
related to such nonperformance by IPA, its Member Physicians, Specialist
Physicians or employees.

               3.02.02   In the event that it is determined by PacifiCare 
that IPA does not obtain and maintain the information set forth in paragraph 
3.02, IPA agrees to assist PacifiCare in obtaining credentialing information 
concerning each Member Physician's and Specialist Physician's education, 
training, references, malpractice liability insurance, hospital staff status, 
hospital clinical privileges, and hospital staff reappointment dates. IPA 
shall obtain from each Member Physician and Specialist Physician a signed 
waiver, acceptable to PacifiCare, allowing PacifiCare access to such 
credentialing information at any acute care hospital or health care facility. 
If IPA is unable to obtain a signed waiver from a Member Physician or 
Specialist Physician, IPA shall obtain the credentialing information directly 
from the acute care hospital or health care facility and make such 
information available to PacifiCare upon request for review and copying.

               3.02.03   IPA agrees to provide access to continuing education 
programs for its Member Physicians and Specialist Physicians in accordance 
with the standards established by the California Medical Association for 
continuing education.  The content and delivery of such continuing education 
programs shall be in the discretion and judgement of IPA, in order to 
maintain high standards for the delivery of Medical Services pursuant to this 
Agreement.  IPA further agrees to gather, correlate, and distribute to its 
Member Physicians and Specialist Physicians, information regarding 
professional medical activities and developments which IPA believes may be of 
assistance in providing Medical Services pursuant to this Agreement.

               3.02.04   IPA agrees to provide reasonable evidence that all
nurses and other ancillary and paramedical personnel who are employed by and
contract with IPA or Specialist Physicians are properly licensed by the State of
California.

general liability insurance in the minimum amounts of one million dollars 
($1,000,000) per person, three million dollars ($3,000,000) per occurrence

coverage, for its

                                          8
<PAGE>

agents and employees, as applicable.  In the event IPA procures a claims made 
policy as distinguished from an occurrence policy, IPA shall procure and 
maintain prior to termination of such insurance, continuing "tail" coverage, 
unless successor policy coverage provides such "tail" protection.  IPA shall 
provide PacifiCare with evidence of such insurance coverage upon PacifiCare's 
request.  IPA shall immediately notify PacifiCare of any material changes in 
insurance coverage and shall provide a certificate of such insurance coverage 
to PacifiCare upon PacifiCare's reasonable request.  In the event IPA 
contracts with independent contractor physicians to provide Medical Services

and their agents to maintain professional liability insurance and general 
liability insurance in the minimum amounts as is usual and customary in the 
community.

with Section 3.05 below.

     3.05 HOSPITAL ADMISSIONS - Whenever IPA determines that a Subscriber on 
IPA's eligibility list requires Hospital Services which are not Emergency 
Services, IPA shall arrange for such Hospital admissions and outpatient 
surgeries through the IPA's Utilization Review Committee and its developed 
utilization review program.  IPA and its Member Physicians shall not serve as 
admitting physicians for any Subscriber without such prior approval except in 
the event that Emergency Services are required.  If IPA or a Member Physician 
admits a Subscriber to a Hospital for Emergency Services, IPA shall notify 
PacifiCare of such admission within the time frames as required in the 
PacifiCare Provider Policies and Procedures Manual, attached hereto as 
Attachment D and incorporated in full herein by reference.  Admissions for 
Emergency Services or Urgently Needed Services shall be made to hospitals 
contracting with PacifiCare, if possible.

     3.06 ELIGIBILITY LIST - IPA shall accept as patients those Subscribers who
are on IPA's eligibility list provided by PacifiCare to IPA.   Member
Physicians and IPA shall be entitled to rely on the most current provided list
until a new list has been approved to IPA.  IPA understands that in order to
update the eligibility list, PacifiCare is dependent on the receipt of
information from HCFA.

     3.07 COLLECTION OF CHARGES FROM SUBSCRIBERS - IPA shall collect 
applicable Copayments from Subscribers upon the rendition of Medical Services 
to Subscribers pursuant to the Secure Horizons Medical and Hospital Plan.  
With the exception of Copayments and charges for non-covered services 
delivered on a fee-for-service basis to Subscribers, IPA shall in no event, 
including, without limitation, to non-payment by PacifiCare, insolvency of

                                          9

<PAGE>

PacifiCare, or breach of the Agreement, bill, charge, collect and deposit, or
attempt to bill, charge, collect or receive any form of payment, from any
Subscriber for Medical Services provided pursuant to this Agreement and for
which Subscriber is entitled under the Secure Horizons Medical and Hospital Plan
in effect for such Subscriber.

          IPA shall not maintain any action at law or equity against a 
Subscriber to collect sums owed by PacifiCare to IPA.  Upon notice of any 
such charge, PacifiCare may terminate this Agreement consistent with the 
provisions contained in Section 7.01.02 and take all other appropriate action 
consistent with the terms of this Agreement to eliminate such charges, 
including, without limitation, requiring IPA and Specialist Physicians to 
return all sums collected as Surcharges from Subscribers or their 
representatives. Nothing in this Agreement, however, shall be construed to 
prevent IPA from providing non-covered Medical Services on a usual and 
customary fee-for-service basis to subscribers.

          IPA's obligations regarding the collection of charges from Subscribers
shall survive the termination of this Agreement with respect to Medical Services
provided during the term of the Agreement without regard to the cause of
termination of this Agreement.

     3.08 COLLECTION OF CHARGES FROM THIRD PARTIES WHEN MEDICARE NOT THE 
PRIMARY PAYOR - IPA and Member Physicians accept payment from PacifiCare 
(plus applicable Copayments) for Medical Services as provided herein as full 
payment for such Medical Services from PacifiCare except as provided herein; 
provided however, when Medicare is not the primary payor for Medical 
Services, such as when the Subscriber is entitled to payment from another 
third party or for payment for a Workers' Compensation claim, or from another 
primary insurance coverage maintained by Subscriber, IPA and Member 
Physicians shall make no demand upon PacifiCare for reimbursement under the 
Individual Subscriber Stop Loss Program as specified in Attachment A3 hereto 
until all primary sources of payment have been pursued and it is determined 
that full payment cannot be obtained within ten (10) months from the date of 
the provision of Medical Services.

     For purposes of accomplishing the intent of the Section 3.08, PacifiCare 
hereby assigns to IPA for collection, any claims or demands against third 
parties for amounts due for Medical Services provided by IPA pursuant to this 
Agreement, subject to the following conditions:

               3.08.01   IPA shall utilize lien forms which are provided by
PacifiCare in the PacifiCare Policies and Procedures Manual or which have been
approved in advance by PacifiCare.  IPA shall notify PacifiCare each time it
pursues and each time it obtains a signed lien from a Subscriber.

                                          10
<PAGE>

               3.08.02   IPA shall not commence any legal or equitable action
against a third party without obtaining the prior written consent of PacifiCare.
It is agreed that collection or demand letters consistent with the PacifiCare
Provider Policies and Procedures Manual shall not constitute the commencement of
legal or equitable action.  Under no circumstances, shall IPA commence any legal
action against a Subscriber.

               3.08.03   IPA shall defend, indemnify and hold PacifiCare
harmless for all actions by IPA which relate to collections of an account
pursuant to this Section 3.08.

               3.08.04   IPA shall perform such collection activities consistent
with the procedures set forth in the PacifiCare Provider Policies and Procedures
Manual.

               3.08.05   PacifiCare may immediately rescind such assignment on a
claim-by-claim basis for any reason by providing written notice of rescission to
IPA.

               In the event IPA receives payment from a third party after 
receipt of payment from PacifiCare, IPA shall reimburse PacifiCare to the 
extent that the combined amounts received from all payors exceeds [  **  ] of 
IPA's usual and customary fee-for-service charges.

     3.09 DUTIES OF IPA UPON TERMINATION DURING PHASE-OUT PERIOD - Should this
Agreement be terminated by IPA pursuant to Section 7.01.01(a) or Section

arrange for Medical Services to Subscribers during the phase-out period as
stated in this Section 3.09.  If this Agreement is terminated for any other
reason by either party or if this Agreement terminates at the end of the Initial

<PAGE>

for Medical Services during the phase-out period pursuant to Section 3.09, if 
applicable, IPA and Member Physicians shall continue to provide or arrange 
for Medical Services to Subscribers until the effective date of transfer of 
such Subscribers to another Participating Medical Group for further treatment 
and written notice of such transfer has been provided by Pacificare to IPA. 
If a Subscriber's care cannot be transferred for the reason of 
hospitalization of Subscriber, continuity of care, or other legally-required 
medical treatment reasons, IPA shall continue to provide or arrange for 
Medical Services for such Subscriber until Pacificare, through consultation 
with the Subscriber's attending participating physician, has made provision 
for the transfer of such Subscriber to another participating provider for 
further Medical Services and has notified IPA of such transfer in writing. 
The payment provisions for any continued Medical services after expiration of 
the phase-out period shall be the lesser of [  **  ] of usual and customary 
fees of the Member Physician or Specialist Physician or the Cost of Care as 
set forth in Attachment A4.

     Notwithstanding the above or any other provisions of this Agreement to the
contrary, IPA agrees that in the event PacifiCare ceases operations for any
reason, including insolvency, IPA shall provide Medical Services and shall not
bill, charge, collect or receive any form of payment from any Subscriber or have
any recourse against a Subscriber for Medical Services provided after PacifiCare
ceases operation. This continuation of Medical Services obligation shall be for
the period for which Subscriber Premiums have been paid, but shall not exceed a
period of thirty (30) days, except for those Subscribers who are hospitalized on

ceases operation or IPA terminates this Agreement until such Subscribers are 
discharged from the hospital. IPA may file a claim with PacifiCare for such 
Medical Services at [  **  ] of IPA's usual and customary fee for service 
charges then in effect.

     IPA agrees that the provisions of this Section 3.10 and IPA's obligations

benefit of the Subscribers.

Subscriber requests for treatment at another facility due to Medical Necessity

request.  PacifiCare and IPA shall exercise reasonable efforts in discouraging
Subscriber transfers at Subscriber's request unless Subscriber can show just
cause for such transfer and IPA deems the transfer medically safe.

               9.01.05   BREACH OF AGREEMENT - IPA shall not be obligated to
continue to refer Subscribers to Hospital upon written notice to IPA by

be construed to require PacifiCare to assign any minimum or maximum number of 
Subscribers to IPA, nor require PacifiCare to utilize the Medical Services of 
IPA for any or all Subscribers in the IPA Service Area.

10.  GOVERNING LAW AND DISPUTE RESOLUTION

     10.01 GOVERNING LAW - This Agreement and the rights and obligations of the
parties hereunder shall be construed, interpreted, and enforced in accordance
with, and governed by, the laws of the State of California, and the United
States and all regulations promulgated pursuant thereto.

     Any provisions required to be in this Agreement by any of the above Acts 
and regulations shall bind PacifiCare and IPA whether or not expressly 
provided in this Agreement.

     10.02 DISPUTE BETWEEN IPA AND SUBSCRIBER NOT GOVERNED BY AGREEMENT - Any
controversies or claims between IPA and Subscriber arising out of IPA's
performance of this Agreement are not governed by this Agreement.  IPA and
Subscriber may seek any appropriate legal action to resolve such controversy or
claim deemed necessary.

     In the event of a dispute between IPA and a Subscriber and upon mutual
Agreement between IPA and such Subscriber, PacifiCare agrees to make available
the Subscriber Grievance Resolution Process described in the Secure Horizons
Medical and Hospital Plan Agreement for resolution of such dispute.  In such
instance, the decision of the PacifiCare Subscriber Satisfaction Committee and

                                          23

<PAGE>

Board of Directors shall not be binding upon the parties except upon agreement
between IPA and the Subscriber.  Nor shall such grievance be subject to binding
arbitration except upon agreement between the parties.  Should IPA and
Subscriber fail to resolve the grievance, IPA and Subscriber may seek any
appropriate legal action deemed necessary by such party.

     10.03 PAYMENT DISPUTES BETWEEN IPA AND SPECIALIST PHYSICIANS - In the event
IPA fails to make a payment to a Specialist Physician within sixty (60) days of
the submission of the bill by Specialist Physician to IPA and the validity and 
the amount of the submitted bill are undisputed, PacifiCare may, in its sole and
absolute discretion, elect to pay the Specialist Physician on behalf of IPA and
deduct such payment from IPA's next monthly Capitation Payment.

     Should a dispute concerning a claim for payment for Medical Services
rendered to Subscribers arise between IPA and a Specialist Physician who is a
Participating Medical Provider, IPA or the Specialist Physician may submit a
written complaint to PacifiCare.  The complaint shall describe the disputed
claim and the basis for the amounts claimed and include the applicable written
agreement between IPA and the Specialist Physician.  PacifiCare shall
investigate the complaint and make a determination of whether or not the claim
is valid and should be paid.  In the event PacifiCare determines that IPA owes
any amount to Specialist Physician, IPA shall make such payment within thirty
(30) days of PacifiCare's determination.  If IPA fails to pay the amount due
within this thirty (30) day period, PacifiCare may deduct the amount owed from
IPA's next monthly capitation payment.  This amount will temporarily be placed
in an account (the "Claims Dispute Account") which shall be established by
PacifiCare.  If IPA or Specialist Physician wishes to contest PacifiCare's
determination, either may do so by initiating an action for binding arbitration
and notifying PacifiCare of such initiation within thirty (30) days of
PacifiCare's determination.  If IPA or Specialist Physician fails to request 
arbitration within thirty (30) days or if the arbitration affirms 
PacifiCare's decision that amounts are owing from IPA to Specialist Physician,
PacifiCare shall release from the Claims Dispute Account the amount owing to
Specialist.  If the arbitration results in a decision that no money or a lesser
amount than was determined by PacifiCare is owing to Specialist Physician,
PacifiCare shall release to IPA the amounts which were erroneously withheld from
IPA's Capitation Payment.

     In the event this Agreement has been terminated prior to PacifiCare's
investigation and written determination and PacifiCare's investigation results
in a determination that IPA owes money to Specialist Physician, PacifiCare may,
in its sole and absolute discretion, elect to pay Specialist Physician on

                                          24

<PAGE>

behalf of IPA and seek reimbursement from IPA. All costs associated with this
arbitration proceeding shall be shared equally between Hospital and IPA.

     10.4 PAYMENT DISPUTES BETWEEN HOSPITAL AND IPA - In the event of a dispute
between Hospital and IPA concerning amounts due or owing under the Hospital
Control Program or as the result of an alleged breach of the exclusive referral
arrangement set forth in Section 9 above, Hospital or IPA may submit a written
complaint to PacifiCare. The complaint shall describe the disputed claim and the
basis for the amounts claimed. PacifiCare shall investigate the complaint and
make a written determination of whether or not the claim is valid and should be
paid. IPA and Hospital shall cooperate with PacifiCare's investigation by
providing in a timely manner all information reasonably requested by PacifiCare.

     In the event PacifiCare determines that IPA owes any amount to Hospital 
or Hospital owes any amount to IPA, the owing party shall make the 
appropriate payment within thirty (30) days of PacifiCare's written 
determination. If the owing party fails to pay the amount due within this 
thirty (30) day period, PacifiCare may deduct the amount owed from the owing 
party's next monthly Capitation Payment. This amount will temporarily be 
placed in an account (the "Claims Dispute Account") which shall be 
established by PacifiCare. If IPA or Hospital wish to contest PacifiCare's 
written determination, either may do so by initiating an action for binding 
arbitration and notifying PacifiCare of such initiation within thirty (30)

Secure Horizons Medical and Hospital Plan.

     12.02     OTHER AGREEMENTS - Nothing in this Agreement shall prevent
PacifiCare and IPA from contracting with each other for provision of services
not covered by this Agreement.

     12.03     REFUSAL BY PHYSICIAN - If IPA or any of its Member Physicians 
refuses Medical Services to a Subscriber assigned to IPA for any reason 
whatsoever, it shall remain the responsibility of IPA to assure that such 
Subscriber receives Medical Services consistent with the terms of this 
Agreement.

Horizons Medical and Hospital Plan individually or through an employer group and
receiving Medical Services shall be Subscribers of PacifiCare. Subscriber and

addresses and telephone numbers of all Subscribers; member, employer and
administrative service manuals and all forms related thereto; and records, files
(other than patient medical files) and lists contained in IPA and PacifiCare
files.

          IPA acknowledges that all such information is confidential and 
proprietary to PacifiCare and that such Subscriber and employer group 
information contains valuable trade secrets of PacifiCare.

          All PacifiCare Subscriber agreements and the information contained
therein regarding PacifiCare, IPA, employer groups, Subscribers or the financial
arrangements between a hospital, IPA and PacifiCare is confidential and
proprietary to PacifiCare.

          IPA shall maintain all Subscriber information and other PacifiCare
trade secret information confidential. IPA shall not disclose or use any
confidential and proprietary information for its own benefit or gain either
during the term of this Agreement or after the date of termination of this

written permission of PacifiCare or the Subscriber.

          12.04.02  INFORMATION CONFIDENTIAL AND PROPRIETARY TO IPA - IPA 
shall provide PacifiCare with a written description of all information

officer, agent, employee or Member Physician of IPA or its assignee or successor
during the Initial Term or any subsequent term of this Agreement and continuing
for a period of one (1) year after the effective date of termination of this
Agreement which may be reasonably interpreted as designed to persuade PacifiCare
Subscribers to discontinue their Subscriber agreements with PacifiCare or to
continue to receive health care services from IPA on a fee-for-service basis or
to encourage PacifiCare Subscribers to participate in the prepaid health service
plan offered by IPA, or any other prepaid health service plan (the 
"Solicitation"). The breach of this Section 12.04.03 during any term of this 
Agreement shall be grounds for termination of this Agreement pursuant to Section

     costs per Subscriber per Year to a specified amount (the "deductible").
     PacifiCare will assume all financial responsibility for the Subscriber in
     excess of the deductible by paying IPA, based on the payment procedure as
     outlined below, [  **  ] in excess of the deductible of the Cost of Care, 
     as defined in Attachment A4, included in full herein by reference.

2.   Deductible: [  **  ] per Subscriber per Year.

3.   Payment Procedures:

     a.   IPA must submit paid claims data in accordance with the procedures
          specified in the PacifiCare Provider Policies and Procedures Manual;

     b.   Cost incurred by IPA for Medical Services provided during the last
          thirty-one (31) days of the Year for which no benefits were payable
          under the ISL Program because such costs were applicable to the
          deductible may be carried forward for inclusion in the ISL
          calculations for the next succeeding Year;

     c.   Medical Services rendered in connection with Worker's Compensation
          cases or where payments of Medical Services provided under Section
          3.01 of this Agreement are receivable through the coordination of
          benefits, third party liability, or any other source of income,
          including copayments, shall not be included in the Cost of Care
          provided in calculating Stop-Loss liability;

     d.   PacifiCare will determine and pay all ISL Program claims within 
          sixty (60) days of receipt of a complete claim;

     e.   For continuing ISL cases (i.e., cases where more than one payment is
          made during the calendar Year), PacifiCare will reimburse IPA
          quarterly based on the submittal of a continuing ISL claim.

     f.   If the Subscriber transfers in the middle of the Year to another
          Participating Medical Group and then exceeds the ISL, the payment for
          all Medical Services in excess of the ISL will be shared
          proportionately among the Participating Medical Groups who provided
          Medical Services to the Subscriber during the Year.

                              HOSPITAL CONTROL PROGRAM

As an incentive for the provision of Hospital Services to Subscribers in a cost
efficient manner, Hospital and IPA shall participate in the PacifiCare Hospital
Control Program.  The Hospital Control Program shall utilize a Claims Fund
Withhold Amount and shall be calculated by comparing the Hospital Services
Budget to the Hospital Services Expense, as such terms are defined below.

1.   HOSPITAL CLAIMS FUND - PacifiCare shall withhold [  **  ] from 
Hospital's monthly capitation payment to create a claims fund (the "Hospital 
Claims Fund") for the payment of claims for Hospital Services provided by 
Outside Providers to Subscribers ("Outside Provider Claims").  If the claims 
paid by PacifiCare behalf of the Hospital during any month exceed the total 
of the Claims Fund, the amount of the deficit shall be withheld by PacifiCare 
from Hospital's next months Capitation Payment in addition to Hospital's 
monthly Claims fund withholding. Monthly withholding from Hospital's 
Capitation Payment shall accrue until the balance in the Claims Fund equals 
[  **  ] of the Hospital's current monthly Capitation Payment rate.  
Subsequent monthly withholdings shall be recalculated and reduced to the 
amount which, when added to the Claims Fund balance, maintains the Claims 
Fund balance at [  **  ] of the Hospital's current monthly Capitation Payment 
Rate.

Hospital shall have the right to review records of all disbursements from the
Claims Fund for compliance with this Agreement and the agreed-upon procedures.
Upon termination of this Agreement, any amounts owed by PacifiCare to Hospital
because of a remaining balance in the Claims Fund, or any amounts owed by
Hospital to PacifiCare because of a deficit in the Claims Fund, will be repaid
as set forth in Section 7.03.

2.   HOSPITAL SERVICES BUDGET - the Hospital Services Budget shall equal the sum
of all Capitation Payments Hospital receives from PacifiCare during the Year,
plus the amount withheld from Capitation as the Claims Fund Withhold Amount.

3.   HOSPITAL SERVICES EXPENSE - Hospital Services Expense shall be equal to the
sum of the following:

a.   INPATIENT EXPENSES AT HOSPITAL - Inpatient costs for services rendered at
Hospital shall be valued as outlined in Hospital Services Valuation Schedule
(Attachment A4); PLUS,

b.   NON-INPATIENT EXPENSES AT HOSPITAL - Other Hospital Services provided by
Hospital other than inpatient services shall be valued as outlined in Hospital
Services Valuation Schedule (Attachment A4) plus,

                                          38

<PAGE>

c.   HOSPITAL SERVICES NOT PROVIDED AT HOSPITAL - The actual amount paid (1) out
of the Claims Fund Withhold Amount for Outside Providers or to PacifiCare
contracting hospitals other than Hospital; and (2) to providers who render
covered Hospital Services outside the Service Area, provided that such services
must be non-Emergency services authorized in writing by IPA, including
admissions for services which are not available within the Service Area; MINUS,

d.   REINSURANCE LIMIT - Any amount of Hospital Services Expense, as defined in
3(a) through (c) above, in excess of [  **  ] per Subscriber per Year; MINUS,

e.   COORDINATION OF BENEFITS - Any amount Hospital receives from third parties
pursuant to Section 3.08 of the Hospital Partial Risk Services Agreement between
PacifiCare and Hospital.

4a.  BUDGET DEFICIT - If the annual Hospital Services Expense is greater than 
the Hospital Services Budget upon completion of the annual calculation, the 
amount of this excess will be referred to as the Budget Deficit.  In the 
event of a Budget Deficit, PacifiCare shall pay the Hospital [  **  ] of the 
Budget Deficit up to [  **  ] per Year.  PacifiCare shall adjust IPA's 
Capitation Payment by retaining [  **  ] of the IPA's subsequent Capitation 
Payment each month until the Budget Deficit amount is paid in full by 
PacifiCare, on behalf of IPA, to Hospital.

In the event of termination of this Agreement, PacifiCare, on behalf of IPA,
shall reimburse Hospital any surplus amounts owed to Hospital within sixty (60)
days of receipt of the final audited annual calculation.

4b.  BUDGET SURPLUS - If the annual Hospital Services Expense is less than 
the Hospital Services Budget for any Year, the amount of this excess shall be 
referred to as a Budget Surplus.  In the event of a Budget Surplus, 
PacifiCare shall pay IPA [  **  ] of the Budget Surplus plus a 
per-member-per-month ("PMPM") bonus as outlined in Attachment A4.  PacifiCare 
will adjust Hospital's Capitation Payment by retaining [  **  ] of Hospital's 
Capitation Payment from the subsequent month and pay this amount to IPA.  
Should Hospital's next month's Capitation Payment not be large enough to 
cover the settlement amount in full, PacifiCare shall continue to adjust 
Hospital's Capitation Payment by retaining [  **  ] from Hospital's 
Capitation Payment for subsequent month(s) until the settlement amount is 
paid in full to IPA, by PacifiCare on behalf of Hospital.

In the event of termination of this Agreement, PacifiCare, on behalf of
Hospital, shall reimburse IPA any surplus amounts owed to IPA within sixty (60)
days of receipt of the final audited annual calculation.

                                          39

<PAGE>

In the event of termination of this Agreement, Hospital shall reimburse IPA any
surplus amounts owed to IPA within thirty (30) days of receipt of the final
audited annual calculation.

5.   YEAR-END SETTLEMENT - Within one hundred and fifty (150) days following the
annual renewal date of this Agreement, PacifiCare shall provide written notice
to Hospital and IPA of comparing the Hospital Services Expense to the Hospital
Services Budget.  Both IPA and Hospital shall have thirty (30) days from the
date of written notice to audit this comparison and submit any revisions to the
comparison to PacifiCare.  Any submitted revisions must represent authorized
Hospital Services and must be approved by both IPA and Hospital in order for the
revisions to be included in any recalculation.  Such approval shall not be
unreasonably withheld.  PacifiCare shall then have thirty (30) days to make any
necessary adjustment to the calculation and return the itemized calculation to
IPA and Hospital.  Such calculation shall be considered the final calculation
unless Hospital, IPA and PacifiCare agree to extend the calculation process.
Any amounts owing shall be paid to the appropriate party, as provided in
Sections 4a and 4b above.

In the event that Hospital Services Expense claims were incurred during the
calendar year in question but were not paid until after the final calculation,
such Hospital Services Expenses shall be carried forward and applied to the
subsequent calendar year's Hospital Control Program as a Hospital Service
Expense for that Year.

     E.   MAMMOGRAPHY

     IPA shall receive [  **  ] for each screening and diagnostic mammography 
study performed above the 1987 PacifiCare-wide baseline, specific to the 
Secure Horizons program, for such studies.  (This baseline equals 267 studies 
per 1,000 adult females.)  The amount due to IPA shall be calculated based 
upon utilization data submitted by IPA and shall be paid within one hundred 
and fifty (150) days of the end of the current calendar year.

     F.   INSTITUTION-TO-INSTITUTION TRANSFERS

     IPA shall bill PacifiCare and PacifiCare shall pay for Medical Services 
provided to Subscribers who enroll with IPA through a transfer from another 
PacifiCare contracted-IPA and who are in a skilled nursing facility, acute 
care hospital, or are receiving any other type of acute institutional care at 
time of enrollment with IPA.  Medical Services provided to such Subscribers 
shall be reimbursed under this special program until the Subscriber is 
discharged from the institutions noted above.  If Subscriber is discharged from 
such institution to home with home health services being provided in-lieu of 
hospitalization, such home health services will be covered under this 
program as well.  Reimbursement to IPA for these Medical Services shall be at 
the Cost of Care rates included in Attachment A4, but no greater than the ISL 
deductible per Subscriber during the Initial Term or any subsequent term of 
this Agreement.

     IPA shall batch these bills together and identify the bills as 
institution-to-institution prior to submitting bill to PacifiCare.  Bills 
must be submitted to PacifiCare no later than sixty (60) days from the 
provision of Medical Services.  Expenses for Medical Services identified as 
institution-to-institution and rendered from

August 1, 1993 through December 31, 1994 only will be included in the 
institution-to-institution program. A final claim must be filed for such 
Medical Services by March 31, 1995 to be reimbursed under this 
institution-to-institution program.

                    DIVISION OF FINANCIAL RESPONSIBILITY

     The attached template outlines the contractual division of financial 
responsibility among IPA, Hospital and PacifiCare, the intent being to 
clarify services and service categories in order to provide for accurate 
administration of this Agreement. As it is impossible to include every 
Medical Service available, this Attachment D serves as a model under which 
broad service categories suggest the appropriate financial responsibility for 
Medical Services, or items not specifically listed. Should an item or service 
not be listed or fit into a broad category, the intent is for an agreement to 
be reached among IPA, Hospital and PacifiCare concerning financial 
responsibilty. The template is based upon coverage/financial responsibility 
within the IPA Service Area ("In Area") unless otherwise specified.

determining whether Subscribers are eligible for Health Care Services on the
basis of the most current Eligibility List supplied to IPA by PacifiCare.
Updated eligibility information shall be available from PacifiCare as needed on
the basis of the most current information supplied PacifiCare by HCFA.

          3.02 STANDARDS - All Medical Services arranged for or provided by IPA
and its Member Physicians shall be provided by professional personnel and at
physical facilities according to generally accepted standards of medical
practice and management in the community. IPA further agrees to provide or
arrange for Referrals to Specialist Physicians and facilities as are necessary,
appropriate, and in accordance with generally accepted standards of medical
practice in the community in compliance with the standards developed by
PacifiCare's Quality Assurance Committee. If IPA contracts with Specialist
Physicians to provide Medical Services under this Agreement, IPA shall require
such Specialist Physicians to provide IPA with the credentialing information set
forth herein. IPA shall obtain and maintain information concerning each Member
Physician's and Specialist Physician's education, training, references,
malpractice liability insurance, hospital staff status, hospital clinical
privileges, and hospital staff reappointment dates. Such information shall be
kept in a form prescribed by or acceptable to PacifiCare. Upon request, the

Code Section 805 ("Section 805"). IPA further agrees to maintain and demonstrate
to PacifiCare upon request compliance with the following:

                     3.02.01 IPA shall ensure that its Member Physicians and 
Specialist Physicians are licensed by the State of California and have

suspension of current DEA registration; (iii) any filing pursuant to Section 
805; (iv) any filing pursuant to the National Practitioner Data Bank; (v) the 
filing of any malpractice claim of more than [  **  ]; and (vi) a change in 
hospital staff status or hospital clinical privileges, including any

                     If IPA fails to obtain and maintain the information set 
forth in Paragraph 3.02 or fails to immediately notify PacifiCare


                                          8
<PAGE>

as set forth in this Paragraph 3.02.01, IPA shall indemnify and hold harmless
PacifiCare from and against any claim, loss, damage, cost, expense or liability
arising out of or related to such nonperformance by IPA, its Member Physicians,
Specialist Physicians or employees.

                     3.02.02 In the event that it is determined by PacifiCare
that IPA does not obtain and maintain the information set forth in paragraph
3.02, IPA agrees to assist PacifiCare in obtaining credentialing information
concerning each Member Physician's and Specialist Physician's education,
training, references, malpractice liability insurance, hospital staff status,
hospital clinical privileges, and hospital staff reappointment dates. IPA shall
obtain from each Member Physician and Specialist Physician a signed waiver,
acceptable to PacifiCare, allowing PacifiCare access to such credentialing
information at any acute care hospital or health care facility. If IPA is unable
to obtain a signed waiver from a Member Physician or Specialist Physician, IPA
shall obtain the credentialing information directly from the acute care hospital
or health care facility and make such information available to PacifiCare upon
request for review and copying.

                     3.02.03 IPA agrees to provide access to continuing
education programs for its Member Physicians and Specialist Physicians in
accordance with the standards established by the California Medical Association
for continuing education. The content and delivery of such continuing education
programs shall be in the discretion and judgement of IPA, in order to maintain
high standards for the delivery of Medical Services pursuant to this Agreement.
IPA further agrees to gather, correlate, and distribute to its Member Physicians
and Specialist Physicians, information regarding professional medical activities
and developments which IPA believes may be of assistance in providing Medical
Services pursuant to this Agreement.

                     3.02.04 IPA agrees to provide reasonable evidence that all
nurses and other ancillary and paramedical personnel who are employed by and
contract with IPA or Specialist Physicians are properly licensed by the State of
California.

         3.03 INSURANCE - IPA shall maintain professional liability insurance
and general liability insurance in the minimum amounts of one million dollars
($1,000,000) per person, three million dollars ($3,000,000) per occurrence
coverage, and three million dollars ($3,000,000) combined single limits
coverage, for its agents and employees, as applicable. In the event IPA procures
a claims made policy as distinguished from an occurrence policy, IPA shall
procure and maintain prior to termination of such insurance continuing "tail"
coverage, unless successor policy coverage provides such "tail" protection. IPA
shall provide PacifiCare with evidence of such insurance coverage upon
PacifiCare's request. IPA shall immediately notify PacifiCare of any material
changes in


                                          9
<PAGE>

insurance coverage and shall provide a certificate of such insurance coverage to
PacifiCare upon PacifiCare's reasonable request. In the event IPA contracts with
independent contractor physicians to provide Medical Services under this
Agreement, IPA will require such independent contractor physicians and their
agents to maintain professional liability insurance and general liability
insurance in the minimum amounts as is usual and customary in the community.

          3.04 REFERRALS - IPA shall refer Subscribers in need of specialty care
services only with the approval of the IPA Utilization Review Committee.
However, in the event that Emergency Services are required, IPA shall comply
with Section 3.05 below.

          3.05 HOSPITAL ADMISSIONS - Whenever IPA determines that a Subscriber
on IPA's eligibility list requires Hospital Services which are not Emergency
Services, IPA shall arrange for such Hospital admissions and outpatient
surgeries through the IPA's Utilization Review Committee and its developed
utilization review program.  IPA and its Member Physicians shall not serve as
admitting physicians for any Subscriber without such prior approval except in
the event that Emergency Services are required. If IPA or a Member Physician
admits a Subscriber to a Hospital for Emergency Services, IPA shall notify
PacifiCare of such admission within the time frames as required in the
PacifiCare Provider Policies and Procedures Manual, attached hereto as
Attachment D and incorporated in full herein by reference. Admissions for
Emergency Services or Urgently Needed Services shall be made to hospitals
contracting with PacifiCare, if possible.

          3.06 ELIGIBILITY LIST - IPA shall accept as patients those Subscribers
who are on IPA's eligibility list provided by PacifiCare to IPA. Member
Physicians and IPA shall be entitled to rely on the most current provider list
until a new list has been provided to IPA.  IPA understands that in order to
update the eligibility list, PacifiCare is dependent on the receipt of
information from HCFA.

          3.07 COLLECTION OF CHARGES FROM SUBSCRIBERS - IPA shall collect
applicable Copayments from Subscribers upon the rendition of Medical Services to
Subscribers pursuant to the Secure Horizons Medical and Hospital Plan. With the
exception of Copayments and charges for non-covered services delivered on a
fee-for-service basis to Subscribers, IPA shall in no event, including, without
limitation, to non-payment by PacifiCare, insolvency of PacifiCare, or breach of
the Agreement, bill, charge, collect and deposit, or attempt to bill, charge,
collect or receive any form of payment, from any Subscriber for Medical Services
provided pursuant to this Agreement and for which Subscriber is entitled under
the Secure Horizons Medical and Hospital Plan in effect for such Subscriber.


                                          10
<PAGE>

          IPA shall not maintain any action at law or equity against a
Subscriber to collect sums owed by PacifiCare to IPA. Upon notice of any such
charge, PacifiCare may terminate this Agreement consistent with the provisions
contained in Section 7.01.02 and take all other appropriate action consistent
with the terms of this Agreement to eliminate such charges, including, without
limitation, requiring IPA and Specialist Physicians to return all sums collected
as Surcharges from Subscribers or their representatives. Nothing in this
Agreement, however, shall be construed to prevent IPA from providing non-covered
Medical Services on a usual and customary fee-for-service basis to Subscribers.

          IPA's obligations regarding the collection of charges from Subscribers
shall survive the termination of this Agreement with respect to Medical Services
provided during the term of the Agreement without regard to the cause of
termination of this Agreement.

          3.08 COLLECTION OF CHARGES FROM THIRD PARTIES WHEN MEDICARE NOT THE
PRIMARY PAYOR - IPA and Member Physicians accept payment from PacifiCare (plus
applicable Copayments) for Medical Services as provided herein as full payment
for such Medical Services from PacifiCare except as provided herein; provided
however, when Medicare is not the primary payor for Medical Services, such as
when the Subscriber is entitled to payment from another third party or for
payment for a Workers' Compensation claim, or from other primary insurance
coverage maintained by Subscriber, IPA and Member Physicians shall make no
demand upon PacifiCare for reimbursement under the Individual Subscriber Stop
Loss Program as specified in Attachment A3 hereto until all primary sources of
payment have been pursued and it is determined that full payment cannot be
obtained within the (10) months from the date of the provision of Medical
Services.

          For purposes of accomplishing the intent of this Section 3.08,
PacifiCare hereby assigns to IPA for collection, any claims or demands against
third parties for amounts due for Medical Services provided by IPA pursuant to
this Agreement, subject to the following conditions:

                    3.08.01    IPA shall utilize lien forms which are provided
by PacifiCare in the PacifiCare Policies and Procedures Manual or which have
been approved in advance by PacifiCare. IPA shall notify PacifiCare each time it
pursues and each time it obtains a signed lien from a Subscriber.

                    3.08.02    IPA shall not commence any legal or equitable
action against a third party without obtaining the prior written consent of
PacifiCare.   It is agreed that collection or demand letters consistent with the
PacifiCare Provider Policies and Procedures Manual shall not constitute the
commencement of legal or


                                          11
<PAGE>

equitable action. Under no circumstances shall IPA commence any legal action
against a Subscriber.

                    3.08.03    IPA shall defend, indemnify and hold PacifiCare
harmless for all actions by IPA which relate to collections of an account
pursuant to this Section 3.08.

                    3.08.04    IPA shall perform such collection activities
consistent with the procedures set forth in the PacifiCare Provider Policies and
Procedures Manual.

                    3.08.05    PacifiCare may immediately rescind such
assignment on a claim-by-claim basis for any reason by providing written notice
of recision to IPA.

                    In the event IPA receives payment from a third party 
after receipt of payment from PacifiCare, IPA shall reimburse PacifiCare to 
the extent that the combined amounts received from all payors exceeds [  **  ]
 of IPA's usual and customary fee-for-service charges.

          3.09 DUTIES OF IPA UPON TERMINATION DURING PHASE-OUT PERIOD-Should
this Agreement be terminated by IPA pursuant to Section 7.01.01(a) or Section
7.01.01(b), IPA shall be released of its obligation to continue to provide or
arrange for Health Care Services to Subscribers during the phase-out period as
stated in this Section 3.09. If this Agreement is terminated for any other
reason by either party or if this Agreement terminates at the end of the Initial
Term or any renewal term, IPA shall not be released of its obligation to
continue to provide or arrange for Health Care Services to Subscribers during
the phase-out period, which phase-out period shall end on the earlier of:

                    3.09.01    Three (3) months from the effective date of
termination of this Agreement, or

                    3.09.02    The date PacifiCare has secured the transfer of
Subscribers to another medical group, individual practice association, or
physician for further treatment, and has notified IPA of such transfer in
writing.

                    Compensation during the phase-out period shall be at the
Capitation Rates set forth in Attachment C hereto.

          3.10 CONTINUING CARE RESPONSIBILITIES - IPA and Member Physicians
shall provide or arrange for Health Care Services to Subscribers for the term of
this Agreement in accordance with Section 3.01 hereof. In the event of
termination of this Agreement and the expiration of IPA's duty to provide or
arrange for Health Care Services during the phase-out period pursuant to Section
3.09, if applicable, IPA and Member Physicians shall continue to provide or
arrange for Health Care Services to Subscribers until the


                                          12
<PAGE>

effective date of transfer of such Subscribers to another Participating 
Medical Group for further treatment and written notice of such transfer has 
been provided by PacifiCare to IPA. If a Subscriber's care cannot be 
transferred for the reason of hospitalization of Subscriber, continuity of 
care, or other legally required medical treatment reasons, IPA shall continue 
to provide or arrange for Health Care Services for such Subscriber until 
PacifiCare, through consultation with the Subscriber's attending 
participating physician, has made provision for the transfer of such 
Subscriber to another participating provider for further Health Care Services 
and has notified IPA of such transfer in writing. The payment provisions for 
any continued Medical Services after expiration of the phase-out period shall 
be the lesser of [  **  ] of the usual and customary fees of the Member 
Physician or Specialist Physician or the Cost of Care as set forth in 
Attachment A4.

          Notwithstanding the above or any other provisions of this Agreement to
the contrary, IPA agrees that in the event PacifiCare ceases operations for any
reason, including insolvency, IPA shall provide Medical Services and shall not
bill, charge, collect or receive any form of payment from any Subscriber or have
any recourse against a Subscriber for Medical Services provided after PacifiCare
ceases operation. This continuation of Medical Services obligation shall be for
the period for which Subscriber Premiums have been paid, but shall not exceed a
period of thirty (30) days, except for those Subscribers who are hospitalized on
an inpatient basis as provided below.

          In the event PacifiCare ceases operations or IPA terminates this 
Agreement on the basis of PacifiCare's failure to make timely Capitation 
Payments, IPA shall continue to arrange for Health Care Services to those 
Subscribers who are hospitalized on an inpatient basis at the time PacifiCare 
ceases operations or IPA terminates the Agreement until such Subscribers are 
discharged from the hospital.  IPA may file a claim with PacifiCare for such 
Health Care Services at [  **  ] of IPA's usual and customary fee for service 
charges then in effect.

          IPA agrees that the provisions of this Section 3.10 and IPA's
obligations herein shall survive the termination of this Agreement without
regard to the cause of termination of the Agreement, and shall be construed to
be for the benefit of the Subscribers.

          3.11 STAFF PRIVILEGES - IPA agrees to have its Member Physicians seek
and obtain (and provide evidence of) staff privileges or other appropriate
access to Hospital.

          3.12 ADMINISTRATIVE GUIDELINES - IPA agrees to perform its duties
under this Agreement in a manner consistent with the reasonable administrative
guidelines provided by PacifiCare, in its Provider Policies and Procedures
Manual, attached hereto as


                                          13
<PAGE>

Attachment D and incorporated in full herein by reference. Subject to Section
12.12 herein, PacifiCare shall notify IPA of any material amendments to the
administrative guidelines, which amendments shall become effective upon thirty
(30) days written notice by PacifiCare to IPA if IPA has not objected to
PacifiCare in writing within the thirty (30) day period to be bound by such
amendments.  IPA approval of such amendments shall not be unreasonably withheld.
If IPA does provide PacifiCare reasonable written objection to be bound by such
amendments within the thirty (30) day period, such amendments to the PacifiCare
Health Plan shall have no force or effect on IPA.

          3.13 UTILIZATION REVIEW - IPA agrees to participate with PacifiCare in
an ongoing utilization review program to promote efficient use of resources. The
IPA's Utilization Review Committee shall meet as frequently as necessary but at
least weekly. The Utilization Review Committee shall keep minutes of the
committee meetings, a copy of which shall be made available to PacifiCare upon
ten (10) days written notice by PacifiCare to IPA. IPA and PacifiCare shall
jointly implement a utilization review system whereby IPA shall notify
PacifiCare of any hospital or skilled nursing facility admissions. A member of
the PacifiCare medical services staff may participate in IPA's Utilization
Review Committee meetings.

          3.14 QUALITY OF HEALTH CARE - IPA agrees to assure quality of Medical
Services by:

                    3.14.01    Assigning PacifiCare Subscribers only to Member
Physicians, Specialist Physicians or Outside Providers meeting quality health
care standards;

                    3.14.02    Inspecting the premises and facilities of its
Member Physicians on a regular basis and allowing PacifiCare to participate in
such inspections upon ten (10) days written notice.

          3.15 QUALITY ASSURANCE AND REMEDIAL PROCEDURES - IPA shall cooperate
with PacifiCare in the operation of PacifiCare's quality assurance program and
IPA shall perform quality assurance review of Health Care Services as brought
before IPA internally or from PacifiCare's Quality Assurance Committee, the
Department of Corporations, the Department of Health and Human Services, HCFA
and any other governmental agencies with regulatory or enforcement jurisdiction
over this Agreement. IPA shall establish and maintain a Quality Assurance
Committee which shall meet at least monthly. A member of the PacifiCare medical
services staff may participate in IPA's Quality Assurance Committee meetings.
The IPA Quality Assurance Committee shall keep minutes of the committee
meetings, a copy of which shall be made available to PacifiCare upon ten (10)
days written notice by PacifiCare to IPA. The task of the Quality Assurance
Committee may be assumed by the Utilization Review Committee described in
Section 3.13; however, in such event, the


                                          14
<PAGE>

Utilization Review and Quality Assurance Committees must hold separately
convened meetings and the minutes of each meeting must be separately maintained.

          IPA shall, at the written request of PacifiCare, make available one
(1) Member Physician from IPA to attend the PacifiCare Quality Assurance
Committee meetings. The intent of this Section is to have at least one Member
Physician from IPA serve for six (6) months on the PacifiCare Quality Assurance
Committee during a three (3) year period.  IPA shall develop written procedures
for remedial action whenever it is determined by PacifiCare's Quality Assurance
Committee that inappropriate or substandard Health Care Services have been
furnished or Health Care Services that should have been furnished have not been
furnished.  Upon request, PacifiCare shall assist IPA in the formulation of such
remedial procedures.

          3.16 COMPLIANCE WITH CIVIL RIGHTS LAWS - IPA shall comply with Title
VI of the Civil Rights Act of 1964, Section 504 of the Rehabilitation Act of
1973 and the Age Discrimination Act of 1975.

          3.17 RECIPROCITY AGREEMENTS - IPA agrees to develop agreements among
PacifiCare's Participating Medical Groups to assure reciprocity of health care
among the Participating Medical Groups for PacifiCare Subscribers. IPA shall
accept non-emergency or specialty Referrals from such other Participating
Medical Groups and such other Participating Medical Groups shall be required to
accept non-emergency or specialty Referrals from IPA. Payment for the foregoing
Referrals shall be no greater than the Cost of Care Rates described in
Attachment A4.

          3.18 INDIVIDUAL STOP-LOSS PROGRAM - The purpose of PacifiCare's
Individual Stop-Loss Program ("ISL") is to limit IPA's costs per Subscriber per
Year to a specified amount (the deductible) in return for a payment of an ISL
Premium. IPA shall purchase Individual Stop Loss Protection coverage from an
outside carrier and/or maintain adequate reserves to ensure coverage of
Catastrophic Cases in lieu of participating in PacifiCare's Individual Stop Loss
Program. Such Individual Stop Loss Protection and/or reserves shall be subject
to PacifiCare's review. Upon PacifiCare's request, IPA shall provide PacifiCare
with evidence of Individual Stop Loss Protection and/or reserves adequate to
cover Catastrophic Cases. In the event IPA fails to make arrangements which meet
the satisfaction of PacifiCare, PacifiCare may, by providing thirty (30) days
notice to IPA, require IPA to purchase Individual Stop Loss Protection coverage
through PacifiCare at the rates charged by PacifiCare for other Participating
IPAs. Notwithstanding Section 12.12, PacifiCare may amend the ISL Premium and
ISL Deductible on the Individual Stop Loss Program coverage offered to
Participating IPAs on an annual basis effective each January 1 by providing
sixty (60) days prior written notice to IPA.


                                          15
<PAGE>

Individual Stop Loss claims for ISL purchased through PacifiCare's Individual
Stop Loss program shall be calculated at the Cost of Care values as set forth in
Attachment A4, of this Agreement.

          3.19 OTHER CONTRACTUAL COMMITMENTS - IPA represents and assures
PacifiCare that contractual commitments with other HMOs, competitive medical
plans and health related entities do not restrict or impair IPA from performing
its duties under this Agreement.

          3.20 DISSEMINATION OF INFORMATION - IPA agrees that PacifiCare may use
IPA's name, address, telephone number, and a listing of IPA's Member Physicians
in any informational material routinely distributed to Subscribers and for other
purposes related to the administration of the Secure Horizons Medical and
Hospital Plan as an indication of IPA's willingness to provide or arrange Health
Care Services to Subscribers.

          Prior to listing or otherwise referencing PacifiCare in any
promotional or advertising brochures, media announcements or other advertising
or marketing material, IPA shall first obtain the prior consent of PacifiCare,
such consent not to be unreasonably withheld.

          3.21 WRITTEN AGREEMENTS - IPA shall secure written agreements,
consistent with the terms of this Agreement and in compliance with all state and
federal law, with all Member Physicians and Specialist Physicians regularly
utilized as a part of IPA's referral system.

          3.22 MEDICAL CARE CRITERIA - IPA shall utilize the criteria for
medical care that is established or approved by PacifiCare's Quality Assurance
Committee as a standard reference in determining appropriate lengths of stay for
hospitalized Subscribers or appropriate utilization patterns for referral to
specialty services.

          3.23 NONDISCRIMINATION - IPA represents and assures that Health Care
Services are provided or arranged for Subscribers in the same manner as such
services are provided to IPA's other patients, except as required pursuant to
this Agreement. Subscribers shall not be subject to any discrimination
whatsoever by IPA in regards to access to Health Care Services.

          3.24 ACCOUNTS PAYABLE SYSTEM - IPA agrees to operate its accounts
payable system in a manner which assures that providers of authorized Medical
Services who are Member Physicians and non-Member Physicians receive payment for
Medical Services rendered to Subscribers within the timeframe specified by
Federal regulation. For a claim which is contested or is not "clean", either
payment must be made to the Member Physician or non-Member Physician, or an
initial determination notice must be sent to the Subscriber within


                                          16
<PAGE>

sixty (60) calendar days of IPA's receipt of such claim from Member Physicians
and non-Member Physicians. Any denied claim which is afterwards determined by
HCFA as payable and which falls under IPA financial responsibility, must be paid
by IPA upon notice and/or receipt of claim. In the event IPA fails to meet the
payment timelines discussed in this Section 3.24, in addition to exercising any
other remedies it may have under this Agreement, PacifiCare may take actions to
assist IPA in operating its accounts payable system including, but not limited
to, paying IPA's Member Physicians and Non-Member Physicians and charging the
claim amount paid against IPA capitation in addition to an administrative fee
for performing such services. PacifiCare shall notify IPA prior to taking any
action to charge claim amount against IPA capitation and IPA will have 30 days
upon notification to reimburse PacifiCare for valid and undisputed claims paid
on behalf of IPA. If the claim amount for a valid and undisputed claim is not
reimbursed at the end of the thirty (30) day notice period, PacifiCare may
charge the claim amount paid against the IPA capitation as discussed in this
section 3.24.  Should IPA dispute such claim or claim amount, the resolution of
such dispute shall be subject to Section 12.16.

          3.25 CATASTROPHIC CASE MANAGEMENT - IPA agrees that PacifiCare's
medical director may be involved in the management and coordination of
Catastrophic Cases. IPA will fully assist PacifiCare in providing information
that may be required in determining the need for a transfer of a Subscriber into
PacifiCare's regional centers for the care of Catastrophic Cases including, but
not limited to, prompt notification of known or suspected Catastrophic Cases.
Detailed procedures for Catastrophic Case management will be mutually agreed
upon by the parties based upon IPA's and PacifiCare's determination of the
Subscriber's transferability. Except in unusual circumstances, regional centers
for care of Catastrophic Cases shall be sought within the IPA Service Area and
surrounding area.

          3.26 CAPACITY REPORTING - IPA will provide to PacifiCare, at the
earliest possible time, notice of any significant changes in the capacity of IPA
to provide or arrange for the Medical Services contemplated by this Agreement
(e.g., addition or deletion of Member Physicians or Specialist Physicians),
including a ninety (90) day written notice in the event IPA is unable to
properly service additional Subscribers. IPA shall still be obligated to provide
or arrange for Health Care Services to Subscribers who are with employer groups
whom PacifiCare had agreed to enroll prior to ninety (90) days from the
effective date of the written notice. PacifiCare shall provide IPA, upon IPA's
request, current marketing information within a reasonable period for purposes
of determining IPA capacity.

          3.27 REPRESENTATION OF IPA MEMBER PHYSICIANS - IPA agrees to represent
its Member Physicians in matters pertaining to the provision of Medical Services
under this Agreement, and that it has


                                          17
<PAGE>

obtained written consent to such representation from its Member Physicians.

          3.28 PERFORMANCE OF MEMBER PHYSICIANS - IPA agrees: (i) to develop
methods for discussion of performance with its Member Physicians, (ii) to assure
correction of performance of its Member Physicians consistent with the
provisions of this Agreement and state and federal law applicable to the Secure
Horizons Medical and Hospital Plan, and (iii) to resolve Conformance Requests.

          3.29 WITHDRAWAL OF AN IPA FACILITY - In the event IPA seeks to
withdraw one or more of the IPA Facilities listed in Attachment F from providing
or arranging for Medical Services to Subscribers under this Agreement, IPA must
notify PacifiCare of such withdrawal in writing at least one hundred and eighty
(180) days prior to the effective withdrawal date; after the effective date of
withdrawal, IPA shall still be responsible to provide or arrange for Health Care
Services to the affected Subscribers at the other IPA Facilities.

          3.30 WITHDRAWAL OF A MEMBER PHYSICIAN/SPECIALIST PHYSICIAN - In the
event IPA seeks to withdraw one or more Member Physicians or Specialist
Physicians from providing or arranging Health Care Services to Subscribers under
this Agreement, IPA must notify PacifiCare of such withdrawal in writing at
least sixty (60) days prior to the effective withdrawal date. After the
effective date of such withdrawal, IPA shall still be responsible to provide or

<PAGE>

          4.05 STATISTICAL INFORMATION AND PROVISION OF DATA - PacifiCare agrees

shall provide, upon request, quarterly reports reflecting the utilization of
Health Care Services rendered by IPA.

          4.06 SERVICES RENDERED TO INELIGIBLE SUBSCRIBERS - PacifiCare 
agrees to reimburse IPA for those Medical Services set forth in Attachment A2 
provided to an ineligible Subscriber if the Subscriber was listed as eligible 
on the most current eligibility list provided to IPA by PacifiCare. If 
PacifiCare is in receipt of a billing to such ineligible Subscriber from IPA 
and proof of having sent the Subscriber or the Subscriber's legal guardian 
two (2) bills no less than thirty (30) days apart, PacifiCare will reimburse 
IPA [  **  ] of IPA's ordinary and customary fee-for-service rates then in 
effect for those Medical Services rendered but no greater than [  **  ] of 
the still uncollected balance. If subsequent to payment by PacifiCare, IPA 
receives any payment from another source for the services, then IPA shall 
reimburse PacifiCare up to the amount previously received from PacifiCare. If 
a Subscriber becomes ineligible for benefits under the Secure Horizons 
Medical and Hospital Plan after IPA or Member Physicians have begun treatment 
of the Subscriber (provided the Subscriber is not hospitalized at the time of 
becoming ineligible), IPA shall be entitled to make all subsequent charges 
for its services directly to the Subscriber. If the Subscriber is 
hospitalized at the time of becoming ineligible, IPA shall be entitled to 
make charges directly to the Subscriber for future medical services, only for 
services provided after the Subscriber is discharged from such hospital 
treatment.

          4.07 DISSEMINATION OF INFORMATION - Except as provided above in
Section 3.20, prior to listing or otherwise referencing IPA in any promotional
or advertising brochures, media announcements or other advertising or marketing
material, PacifiCare shall first obtain the prior consent of IPA, such consent
not to be unreasonably withheld.

5.        COMPENSATION

          5.01 CAPITATION PAYMENTS - PacifiCare shall make monthly Capitation
Payments to IPA as outlined in Attachment C, attached hereto and incorporated in
full herein by reference, due and payable on the tenth (10th) day of the month
for the current month's Medical Services.

          5.02 ADDITIONAL PAYMENTS - Pacificare and IPA agree to provide
payments to each other in accordance with the terms of the


                                          19
<PAGE>

following programs, if applicable: Hospital Incentive Program, Individual
Stop-Loss Program, Benefit Withhold Incentive Program and Mammography
Reimbursement Program as specified in Attachments A, A3, E and C
respectively, incorporated in full herein by reference.

        To the extent that each party owes an amount to the other party in the
risk programs noted above, IPA agrees that PacifiCare shall combine the results
of all applicable risk programs such that one aggregate payment is payable to or
receivable from IPA. A fully detailed accounting of the results of each program
shall accompany the aggregate payment or notice of amount due.

        5.03 ADEQUACY OF COMPENSATION - Except as otherwise provided herein,
IPA shall accept the payments specified in this Agreement as payment in full for
all Medical Services provided Subscribers during each month for which such
payments are to be received by IPA from PacifiCare. In the event PacifiCare
fails to make any payments to IPA as provided herein, whether from PacifiCare's
insolvency or otherwise, Subscribers shall not be liable to IPA or its Member
Physicians under any circumstances for Medical Services. Surcharges for Medical
Services provided or arranged by IPA or Member Physicians are prohibited; upon
notice of the existence of any Surcharge, PacifiCare will take appropriate
action consistent with the terms of this Agreement to eliminate such Surcharges.

        5.04 REINSURANCE - The purpose of the reinsurance program described 
herein is to limit IPA's risk for Hospital Services under the Hospital 
Control Program to a specified amount per Subscriber per Year (the 
"Reinsurance Deductible") in return for a payment of a Reinsurance Premium. 
For the 1996 calendar year, the Reinsurance Deductible shall be [  **  ] per 
Subscriber per Year and the Reinsurance Premium shall equal [  **  ] of the 
Monthly HCFA Payment per Subscriber per month. Notwithstanding Section 12.12, 
PacifiCare may amend the Reinsurance Premium and Reinsurance Deductible on an 
annual basis effective each January 1 by providing sixty (60) days prior 
written notice to IPA.

Reinsurance claims shall be calculated at the Cost of Care values as set forth
in Attachment A5, Sections c.1, c.2, and c.3 of this Agreement.

        5.05 MOST FAVORED PLAN - IPA represents that, during the term of this
Agreement, the compensation rates payable under this Agreement are and shall
continue to be equal to or less than the rates charged under other IPA
agreements for the provision of services to enrollees of health care service
plans ("Competing Plan Agreements"), when such rates are adjusted to reflect
different risk levels and programs under the Competing Plan Agreements (the
"Adjusted Rates").  If at any time IPA agrees or has agreed to accept lower
Adjusted Rates under a Competing Plan Agreement than


                                          20

<PAGE>

the rates set forth in this Agreement, or any amendment hereto, IPA shall
immediately notify PacifiCare in writing of such agreement and the applicable
lower Adjusted Rates. Within thirty (30) days thereafter, PacifiCare and IPA
shall meet to discuss implementation of new compensation rates under this
Agreement which shall be equal to or less than the Adjusted Rates accepted under
the Competing Plan Agreement. If the parties fail to agree to implementation
procedures for the new rates within thirty (30) days of the effective date of
the Competing Plan Agreement, the compensation rates under this Agreement will
be lowered upon notice to IPA from PacifiCare to equal the lower Adjusted Rate.
The new compensation rates shall be effective the date the lower Adjusted Rates
become effective under the Competing Plan Agreement. IPA's failure to notify
PacifiCare of the acceptance of lower Adjusted Rates from a Competing Plan shall
be grounds for termination of this Agreement by PacifiCare pursuant to Section
7.01.02(d)."

Notwithstanding the above, this Section 5.05 shall have no effect for any period
of time in which the total number of Members enrolled in the IPA Service Area in
the Secure Horizons Health Plan (including Members assigned to IPA and
Participating Medical Groups other than IPA) exceeds forty percent (40%) of the
total number of Medicare eligible persons in the IPA Service Area. The number of
PacifiCare Members shall be determined by PacifiCare utilizing current
enrollment data. The number of Medicare eligible persons in the IPA Service Area
shall be calculated by either party utilizing independent data acceptable to
both parties.  Either party may dispute the other's calculation of the number of
Medicare eligible persons or IPA may dispute PacifiCare's determination of the
number of PacifiCare Members by providing written notice to the appropriate
party. Upon the receipt of such notice, the parties shall select a third party
acceptable to both PacifiCare and the IPA who shall be charged with the
responsibility of determining the number of Medicare eligible persons and/or the
number of PacifiCare Members, as applicable.

Procedures for determining what constitutes Adjusted Rates and procedures for
auditing the provisions of this Section 5.05 shall be mutually agreed upon by
PacifiCare and IPA, through consultation with a mutually agreed to independent
third party. Such procedures will include audit by a mutually agreed to
independent third party auditor.

6.      TERM OF AGREEMENT

        6.01 TERM - The term of this Agreement shall be for fifty-four (54)
months and the commencement date shall be July 1, 1996. A "Year" under this
Agreement shall begin on January 1 and end on December 31. The term of this
Agreement shall be automatically extended for one (1) year on each successive
January 1 unless either party provides the other with written notice of such
party's


                                          21

<PAGE>

intention not to extend the term no less than one hundred eighty (180) days
prior to the January 1 renewal date or until this Agreement is appropriately
terminated by either party as provided in Section 7 herein.  The parties
understand that on each successive January 1, a term of sixty (60) months will
be in effect unless the Agreement has been terminated pursuant to Section 7 or
unless notice of non-renewal has been provided as set forth in this Section
6.01. Upon renewal of the Initial Term and any subsequent term, the applicable
rates of compensation specified in this Agreement shall apply unless otherwise
agreed upon by the parties in writing.

7.      TERMINATION

        7.01 TERMINATION OF AGREEMENT WITH MATERIAL CAUSE - Either party, as
appropriate, may terminate this Agreement for material cause as set forth in
Sections 7.01.01 or 7.01.02 hereof subject to the notice and cure periods set
out in Section 7.02 hereof, if applicable. In the event either party seeks to so
terminate this Agreement, the terminating party shall give written notice of
termination stating the actions of the other party constituting material cause

        8.04 RIGHT TO INSPECT - IPA shall provide access at reasonable times

shall copy all active PacifiCare Subscriber patient medical files in IPA's
possession and forward such files to another provider of Medical Services

        within the sixty (60) day notice period, or if IPA does not meet the
        mutually agreed upon time lines for development, PacifiCare shall be
        released of its obligations as described in this Section 9.03.01(e) and
        the subsections hereto.

                         iv.  PacifiCare shall not be restricted from
        maintaining contracts with Participating Medical Groups under contract
        with PacifiCare as of the Strategic Alliance Effective Date ("Existing
        PMGs") and Existing PMGs also identified as Strategic Allies by
        PacifiCare shall not be restricted from adding additional facilities or
        expanding their coverage area under their PacifiCare services
        agreements. Notwithstanding the above, IPA shall be restricted from
        adding additional Prospect Medical Group, Inc. Networks other than

               9.03.03   TERMINATION OF STRATEGIC ALLY STATUS. In the event 
that either PacifiCare or IPA ceases to meet any of the obligations specified 
in Section 5.05 or Section 9.03 and PacifiCare or IPA fails to come into 
compliance with such requirements within the notice period specified below, 
the Strategic Ally status shall terminate at the end of the notice period. 
The notice period shall be 30 days from the receipt of written notice by 
either party. In addition, Strategic Ally status shall be terminated 
immediately in the event that PacifiCare acquires, is acquired by, or merges 
with another health care service plan and this provision would place the new 
or surviving entity in breach of any other contract or in violation of any 
state or federal law. PacifiCare may also terminate IPA's Strategic Ally 
status upon thirty (30) days notice to IPA if IPA merges with or into another 
entity, regardless of whether IPA is the surviving entity, or in the event of 
a change in ownership of more than [  **  ] of the shares of IPA. Upon the 
termination of Strategic Ally status, PacifiCare's obligations as set forth 
in Section 9.03.01 above shall immediately terminate. Termination of 
Strategic Ally status shall be the sole remedy of PacifiCare and IPA in the 
event of breach by IPA or PacifiCare of the obligations set forth in this 
Section 9.03.

               9.03.04   ADDITION OF NEW IPA FACILITIES. IPA Facilities added
outside the IPA Service Area after the Strategic Alliance Effective Date shall
not be granted Strategic Ally status except as specifically agreed in writing by
PacifiCare and IPA.

               9.03.05   IPA EXCLUSIVITY - As a condition to maintaining
Strategic Ally status and in recognition of PacifiCare's desire to enhance the
quality of care provided to its Subscribers by ensuring continuity of care,
better control and standardization in procedures and full-time availability of
services, IPA agrees that it shall not enter into any new agreements, other than
those currently in force with an entity of the St. Jude Network, to provide or
arrange Medical Services to Medicare beneficiaries who are subscribers or
enrollees of a health maintenance organization, competitive medical plan or
other similar entity that contracts with HCFA on a risk basis ("Competitor Plan
Enrollees").

10. GOVERNING LAW AND DISPUTE RESOLUTION

        10.01 GOVERNING LAW - This Agreement and the rights and obligations of
the parties hereunder shall be construed, interpreted, and enforced in
accordance with, and governed by, the laws of the State of California, and the
United States and all regulations promulgated pursuant thereto.

        Any provisions required to be in this Agreement by any of the above
Acts and regulations shall bind PacifiCare and IPA whether or not expressly
provided in this Agreement.


                                          29
<PAGE>

         10.02 DISPUTES BETWEEN IPA AND SUBSCRIBER NOT GOVERNED BY AGREEMENT -
Any controversies or claims between IPA and Subscriber arising out of IPA's
performance of this Agreement are not governed by this Agreement.  IPA and
Subscriber may seek any appropriate legal action to resolve such controversy or
claim deemed necessary.

          In the event of a dispute between IPA and a Subscriber and upon mutual
agreement between IPA and such Subscriber, PacifiCare agrees to make available
the Subscriber Grievance Resolution Process described in the Secure Horizons
Medical and Hospital Plan Agreement for resolution of such dispute. In such
instance, the decision of the PacifiCare Subscriber Satisfaction Committee and
Board of Directors shall not be binding upon the parties except upon agreement
between IPA and the Subscriber.  Nor shall such grievance be subject to binding
arbitration except upon agreement between the parties. Should IPA and Subscriber
fail to resolve the grievance, IPA and Subscriber may seek any appropriate legal
action deemed necessary by such party.

         10.03 PAYMENT DISPUTES INVOLVING IPA - In the event IPA fails to make a
payment to a Specialist Physician within sixty (60) days of the submission of
the bill by Specialist Physician to IPA and the validity and the amount of the
submitted bill are undisputed, PacifiCare may, in its sole and absolute
discretion, elect to pay the Specialist Physician on behalf of IPA and deduct
such payment from IPA's next monthly Capitation Payment.

         Should a dispute concerning a claim for payment for Medical Services
rendered to Subscribers arise between IPA and a Specialist Physician who is a
Participating Medical Provider, IPA or the Specialist Physician may submit a
written complaint to PacifiCare. The complaint shall describe the disputed
claims and the basis for the amounts claimed and include the applicable written
agreement between IPA and the Specialist Physician.  PacifiCare shall
investigate the complaint and make a determination of whether or not the claim
is valid and should be paid. In the event PacifiCare determines that IPA owes
any amount to Specialist Physician, IPA shall make such payment within thirty
(30) days of PacifiCare's termination. If IPA fails to pay the amount due within
this thirty (30) day period, PacifiCare may deduct the amount owed from IPA's
next monthly capitation payment. This amount will temporarily be placed in an
account (the "Claims Dispute Account") which shall be established by PacifiCare.
If IPA or Specialist Physician wishes to contest PacifiCare's determination,
either may do so by initiating an action for binding arbitration and notifying
PacifiCare of such initiation within thirty (30) days of PacifiCare's
determination. If IPA or Specialist Physician fails to request arbitration
within thirty (30) days or if the arbitration affirms PacifiCare's decision that
amounts are owing from IPA to Specialist Physician, PacifiCare shall release
from the Claims Dispute Account the amount owing to Specialist.  If the
arbitration results in a decision that no money or a lesser amount


                                          30
<PAGE>

than was determined by PacifiCare is owing to Specialist Physician, PacifiCare
shall release to IPA the amounts which were erroneously withheld from IPA's
Capitation Payment.

         In the event this Agreement has been terminated prior to PacifiCare's
investigation and written determination and PacifiCare's investigation results
in a determination that IPA owes money to Specialist Physician, PacifiCare may,
in its sole and absolute discretion, elect to pay Specialist Physician on behalf
of IPA and seek reimbursement from IPA.

information proprietary to IPA which is confidential and contains trade secrets
of IPA ("IPA Information").  PacifiCare shall maintain IPA Information
confidential. PacifiCare shall not disclose or use any IPA Information for its
own benefit either


                                          32

during the term of this Agreement or after the effective date of termination of
this Agreement. Upon termination of this Agreement, PacifiCare shall provide and
return to IPA all IPA Information in its possession in a manner to be specified
by IPA.  PacifiCare shall cooperate with IPA in maintaining the confidentiality
of IPA Information at all times.

                              12.04.03 SOLICITATION OF PACIFICARE SUBSCRIBERS OR
EMPLOYER GROUPS - IPA shall not directly or indirectly engage in the practice of
solicitation or the patronage of PacifiCare's Subscribers or employer groups
without PacifiCare's prior written consent. Solicitation shall mean conduct by
an officer, agent, employee or Member Physician of IPA or its assignee or
successor during the Initial Term or any subsequent term of this Agreement and
continuing for a period of one (1) year after the effective date of termination
of this Agreement which may be reasonably interpreted as designed to persuade
PacifiCare Subscribers to discontinue their Subscriber agreements with
PacifiCare or to continue to receive health care from IPA on a fee-for-service
basis or to encourage PacifiCare Subscribers to participate in the prepaid
health service plan offered by IPA, or any other prepaid health service plan
(the "Solicitation").    The breach of this Section 12.04.03 during any term of
this Agreement shall be grounds for termination of this Agreement pursuant to
Section 7.01.02 of this Agreement.

         12.05 CONFIDENTIALITY OF THIS AGREEMENT - To the extent reasonably
possible, each party agrees to maintain this Agreement as a confidential
document and not to disclose the Agreement or any of its terms without the
approval of the other party.

         12.06 ASSIGNMENT - This Agreement and the rights, interests, and
benefits hereunder shall not be assigned, transferred, pledged, or hypothecated
in any way by IPA or PacifiCare and shall not be subject to execution,
attachment or similar process, nor shall the duties imposed herein be
subcontracted or delegated without the written consent of the other party.
Notwithstanding, PacifiCare may assign, transfer, pledge or hypothecate this
Agreement and its rights, interests and benefits hereunder to any entity which
has at least majority control of PacifiCare or to any entity of which PacifiCare
has at least majority control.

         12.07 INVALIDITY OF SECTIONS OF AGREEMENT - The unenforceability or
invalidity of any paragraph or subparagraph of any section or subsection of this
Agreement shall not affect the enforceability and validity of the balance of
this Agreement.

         12.08 WITHDRAWAL OF SUBSCRIBERS BY PACIFICARE - PacifiCare reserves the
right to withdraw from IPA all or part of the Subscribers from IPA whose Health
Care Services are not being properly provided pursuant to this Agreement.
PacifiCare shall provide written notice to IPA of such withdrawal and the
reasons


                                          33
<PAGE>

therefore. PacifiCare shall then allow IPA thirty (30) days from the date of
such notice to correct deficiencies.  If such deficiencies are not corrected to
PacifiCare's satisfaction within said period, PacifiCare may withdraw its
Subscribers as provided in this Section 12.08 and remove IPA's name from
PacifiCare's marketing materials.

          12.09 TRANSFER OF SUBSCRIBERS - PacifiCare and IPA shall exercise
reasonable efforts in discouraging Subscriber transfers except at re-enrollment
periods, or when a Subscriber can show just cause for such transfer and
PacifiCare agrees to such transfer. Nevertheless, PacifiCare may require
transfer of Subscribers assigned to IPA for any reason; or, IPA may request
transfer of Subscribers assigned to it by PacifiCare to other IPAs for cause or
if the capacity of IPA is overburdened so that the provision of Medical Services
as required by this Agreement is affected; all such transfers shall be
consistent with the PacifiCare Provider Policies and Procedures Manual.

         12.10 CAPTIONS - Captions in this Agreement are descriptive only and do
not affect the intent or interpretation of the Agreement.

         12.11 AMENDMENT - This Agreement may be amended or modified only by
mutual written consent of the parties. Notwithstanding the foregoing sentence,
PacifiCare may amend this Agreement upon thirty (30) days written notice to IPA
in order to maintain compliance with applicable federal and state laws;
provided, however, any such amendment which affects a material duty or
responsibility of IPA and has a material adverse economic effect upon IPA as
reasonably demonstrated by IPA to PacifiCare, shall be subject to the provisions
of Section 12.12 below.

          12.12 MODIFICATIONS OF THIS AGREEMENT AND/OR PACIFICARE PROVIDER
POLICIES AND PROCEDURES MANUAL AND/OR PACIFICARE HEALTH PLAN - Anything to the
contrary herein notwithstanding, in the event of any material modification of
this Agreement and/or the PacifiCare Provider Policies and Procedures Manual
and/or the Secure Horizons Medical and Hospital Plan that (i) affects a material
duty or responsibility of IPA, and (ii) causes a material adverse economic
effect to IPA, IPA and PacifiCare shall seek to agree to an amendment to this
Agreement which satisfactorily addresses the effect on IPA's material duty or
responsibility and reimburses the material economic detriment caused to IPA. In
the event such an agreement cannot be reached within sixty (60) days after the
date PacifiCare gives IPA written notice of such modification, such modification
shall not be effective.

         12.13 TERMS; SECTIONS - Unless otherwise indicated, all terms in any
appropriate attachments, addendums and amendments hereto shall have the same
meaning attributed to such terms in the body of


                                          34

this Agreement and references to section numbers are to the appropriate sections

         12.14 IPA'S AUTHORIZED REPRESENTATIVE - Unless otherwise indicated in
writing to PacifiCare, IPA warrants and authorizes its administrator to act as
its fully authorized representative to represent IPA and Member Physicians in
this Agreement and to receive any and all communications and notices hereunder.

         12.15 ATTORNEYS' FEES AND COSTS - If any action at law or suit in
equity is brought to enforce or interpret the provisions of this Agreement or to
collect any monies due hereunder, the prevailing party shall be entitled to
reasonable attorneys' fees and reasonable costs, together with interest thereon
at the highest rate provided by law, in addition to any and all other relief to
which it may otherwise be entitled.

          12.16 ARBITRATION - Any controversy, dispute or claim between
PacifiCare and IPA arising out of the interpretation, performance or breach of
this Agreement shall be resolved by binding arbitration at the request of either
party, in accordance with the rules of the American Arbitration Association. The
arbitrators shall apply California substantive law and federal substantive law
where state law is preempted.    Civil discovery for use in such arbitration may
be conducted in accordance with the California Code of Civil Procedure and the
California Evidence Code, and the arbitrator selected shall have the power to
enforce the rights, remedies, duties, liabilities, and obligations of discovery
by the imposition of the same terms, conditions and penalties as can be imposed
in like circumstances in a civil action by a superior court of the State of
California. The provisions of California Code of Civil Procedure Sections 1283
and 1283.05 concerning the right to discovery and the use of depositions in
arbitration are incorporated herein by reference and made applicable to this
Agreement.

         The arbitrators shall have the power to grant all legal and equitable
remedies and award compensatory damages provided by California law, but shall
not have the power to award punitive damages. The arbitrators shall prepare in
writing and provide to the parties an award including factual findings and the
legal reasons on which the decision is based. The arbitrators shall not have the
power to commit errors of law or legal reasoning, and the award may be vacated
or corrected pursuant to California Code of Civil Procedure Sections 1286.2 or
1286.6 for any such error. The cost of arbitration shall be shared equally by
both parties.

                                     COST OF CARE

For purposes of this Agreement, the Cost of Care for Medical Services provided
or arranged by IPA to Subscribers shall equal:

     a)   For services provided to Subscribers by Member Physicians who practice
          at IPA Facilities, [  **  ] the Medicare Locality Fee Schedule for 
          Participating Providers as published by the Part B carrier.

     b)   For services provided to Subscribers by Specialist Physicians or
          Outside Providers, [  **  ] of the fees actually paid by IPA.

General guidelines and special situations:

     1.   Services provided by IPA which are not a benefit, as specified in the
          Subscriber's Secure Horizons Medical and Hospital Agreement, will not
          be considered a part of Cost of Care.

     2.   The Cost of Care of Anesthesia Professional Services rendered by IPA
          shall be set at [  **  ] of usual and customary charges. The Cost of
          Care for Anesthesia Professional Services rendered through an outside
          referral or reciprocity referral shall be set at the [  **  ] of usual
          and customary charges, whichever is lower.

     3.   Any Medical Services provided where payment is considered collectible
          through the coordination of benefits, third-party liability, Worker's
          Compensation, or any other source including Copayments, shall not be
          included in the Cost of Care.  If, at a later date, these claims are
          not collectible, or only partially collectible, then these services
          will be included in the relevant programs, based on the Cost of Care
          calculation cited above.

                             UTILIZATION CONTROL PROGRAM

     As an incentive for the cost effective provision of Hospital Services,
In-Area Emergency Services and other selected services, PacifiCare and IPA shall
establish a Utilization Control Program. The Utilization Control Program shall
utilize a Withhold Amount, as defined below, and shall be calculated by
comparing the Budget to the Expenses, as such terms are defined below.

A.   WITHHOLD AMOUNT - PacifiCare shall withhold from IPA's monthly 
Capitation Payment an amount equal to [  **  ] of the Monthly HCFA Payment to 
apply to IPA's share of Budget Deficits, if any. PacifiCare may prospectively 
adjust the Withhold Amount on a quarterly basis based upon the results of the 
Utilization Control Program calculation. If the Agreement is terminated or 
non-renewed pursuant to Section 6 or Section 7 of the Agreement, PacifiCare 
may choose to adjust the Withhold Amount at the time that the notice of 
termination or non-renewal is served.

B.   BUDGET - The Budget shall equal the sum of 1. and 2. below:

     1.   For Hospital Services, [  **  ] of the Monthly HCFA Payment for those
          Subscribers designating IPA as their Participating Medical Group ("IPA
          Subscribers"), MINUS [  **  ] of the Monthly HCFA Payment in 
          consideration of the Reinsurance Program as set forth in subsection 
          (c) (4) herein.

     2.   For outpatient prescription drugs and other Benefit Withhold Services,
          [  **  ] of the monthly revenue received from HCFA for Subscribers who
          have designated IPA as their Participating Medical Group, plus 
          [  **  ] per member per month rebate for drugs ("Drug Rebate") ordered
          through Prescription Solutions during any calendar year. 
          Notwithstanding Section 12.12, PacifiCare may amend the Drug Rebate on
          an annual basis effective each January 1 by providing sixty (60) days
          prior written notice to IPA.

C.   EXPENSES - Expenses shall be valued as the total of the following:

     1.   INPATIENT EXPENSE AT HOSPITAL - Inpatient costs for Hospital Services
          rendered at Hospital, valued at the amount paid to Hospital by
          PacifiCare; plus,


                                          46
<PAGE>

     2.   NON-INPATIENT EXPENSES AT HOSPITAL - Other Hospital Services provided
          by Hospital other than inpatient services, valued at the amount paid
          to Hospital by PacifiCare; plus,

     3.   HOSPITAL SERVICES NOT PROVIDED AT HOSPITAL - The actual amount paid by
          PacifiCare for Hospital Services not provided by Hospital; MINUS

     4.   REINSURANCE LIMIT - Any amount of Hospital Services Expense, as
          defined in subsection (c) (1) through (3) above, in excess of the
          Reinsurance Deductible specified in Paragraph 5.04 of this Agreement;
          MINUS,

     5.   COORDINATION OF BENEFITS - Any amount received by PacifiCare from
          third parties as the result of coordination of benefits and third
          party recoveries for Hospital Services; plus,

     6.   Outpatient prescription drugs; plus

     7.   Acute hospital days greater than 150 per year; plus

     8.   Respite Care; plus,

     9.   Immunosuppressive drugs; plus,

     10.  Mammography (see Section E of Attachment C)

D.   PAYMENTS TO IPA UNDER UTILIZATION CONTROL PROGRAM

     1.   BUDGET EXCEEDS EXPENSES - In the event the annual Budget exceeds
          annual Expenses, PacifiCare shall pay IPA the Withhold Amount, if any,
          plus an amount equal to [  **  ] of the amount by which the annual
          Budget exceeds annual Expenses, up to a limit of [  **  ] of the 
          annual Budget.

     2.   EXPENSES EXCEED BUDGET - In the event that annual Expenses exceed
          annual Budget, PacifiCare shall pay IPA the Withhold Amount, if any,
          minus an amount equal to [  **  ] of the amount by which Expenses
          exceed the Budget, up to a limit of [  **  ] of the annual Budget.

          To the extent that the portion of the calculated deficit for which IPA
          is responsible exceeds the Withhold Amount, IPA shall not be entitled
          to any of the Withhold Amount. After the Withhold Amount has been
          exceeded, any remaining portion of the deficit for which IPA is
          responsible shall be carried forward into the succeeding term. An
          amount equal to this remaining portion of the deficit will be withheld
          from IPA's monthly Capitation Payment, using a mutually agreed upon
          payment schedule, not to exceed one (1) Year.


                                          47
<PAGE>

          Should this Agreement terminate leaving no successive term to carry
          forward an existing deficit amount, such deficit amount shall be due
          and payable by IPA to PacifiCare within one hundred fifty (150) days
          of the effective date of termination of this Agreement.

E.   SETTLEMENT OF UTILIZATION CONTROL PROGRAM PAYMENTS

     PacifiCare shall make interim Utilization Control Program calculations and
     payments, if any, on a quarterly basis within sixty (60) days after the end
     of each calendar quarter from the Effective Date. Quarterly payments will
     be made to IPA based on the calculations specified in subsection (D) above.
     The Expense figure used in quarterly incentive program calculations shall
     also include an "Incurred But Not Reported" factor in order to account for
     outstanding Medical Services claims. PacifiCare shall make an annual
     Utilization Control Program payment to IPA within one hundred and fifty
     (150) days of the end of each Year.

                                    COMPENSATION

A. BENEFIT WITHHOLD

          PacifiCare shall retain [  **  ] of the revenue received each month 
from HCFA to fund the following Subscriber benefits. These benefits are 
outlined more specifically in the Secure Horizons Medical and Hospital 
Subscriber Agreement.

              1) Outpatient prescription drugs
              2) Acute hospital days greater than 150 per year
              3) Respite Care
              4) Immunosuppressive Drugs
              5) Mammography (see Section E below)

          IPA shall be given the opportunity to share in any savings which may
be present in the Utilization Control Program as described in Attachment A5.

In addition, for the Secure Horizons preventative dental benefit, PacifiCare 
shall retain an additional [  **  ] of the revenue received each month from 
HCFA to fund the preventative dental benefit.

B. MONTHLY HCFA PAYMENT

          PacifiCare shall pay IPA [  **  ] of the Monthly HCFA Payment, LESS 
the applicable ISL Premium identified in Attachment A3 as payment for 
Individual Stop Loss coverage. The percent of monthly HCFA Payment stated 
above includes [  **  ] which is the value of IPA's covenant not to compete 
as outlined in Section 9 of this Agreement. Should IPA breach the covenant 
not to compete, PacifiCare shall reduce the percent of monthly HCFA Payment 
by this [  **  ] commencing the month in which the breach occurs. It is 
understood that any existing Medicare Risk arrangements that the IPA 
currently has in effect does not constitute a breach for this purpose. The 
payment per Subscriber per month by PacifiCare to IPA shall be increased or 
decreased to reflect increases or decreases made by HCFA in the Monthly HCFA 
Payment. PacifiCare shall make monthly retroactive adjustments to reflect 
adjustments made by HCFA, if any.

PacifiCare shall provide IPA appropriate documentation in support of the actual
Capitation Payment made. Should IPA desire additional billing information,
PacifiCare shall make available for inspection other mutually agreed upon
documents, upon thirty (30) days prior written notice from IPA. IPA shall have
the right to reasonably audit PacifiCare's books and records directly relating
only to IPA's Capitation Payment determinations upon thirty (30) days prior
written notice at IPA's sole expense.

E.        MAMMOGRAPHY

          IPA shall receive [  **  ] for each screening and diagnostic

The attached template outlines the division of financial responsibility between
IPA, the Hospital Incentive Program (HIP), and PacifiCare (PC), the intent being
to clarify Medical Service and Hospital Service categories in order to provide
for accurate administration. As it is impossible to include every service
available, the template serves as a model under which broad Medical Service and
Hospital Service categories suggest the appropriate financial responsibility for
services or items not specifically listed.

COMMISSION BY PROSPECT MEDICAL HOLDINGS, INC. AS PART OF A REQUEST FOR 
CONFIDENTIAL TREATMENT."


                              POINT-OF-SERVICE AMENDMENT
                    TO IPA MEDICARE SHARED RISK SERVICES AGREEMENT


     The undersigned parties to the IPA Medicare Shared Risk Services Agreement
(the "Agreement") by and between PacifiCare of California ("PacifiCare") and
Prospect Medical Group, Inc. ("IPA") do hereby amend the Agreement with
reference to the following facts:

     WHEREAS, PacifiCare intends to introduce the Secure Horizons
Point-of-Service Plan, as defined below, beginning in 1996;

     WHEREAS, IPA shall provide or arrange Health Care Services to Secure
Horizons Point-of-Service Plan Subscribers under the same terms and conditions
as other Secure Horizons Health Plan Subscribers;

     WHEREAS, IPA shall have no financial responsibility for Out-of-Network
Services; and

     WHEREAS, PacifiCare and IPA desire to establish a Secure Horizons
Point-Of-Service Control Program for the purpose of providing a financial
incentive for the control of Out-of-Network Services.

     NOW THEREFORE, the Agreement shall be amended as follows:

1.   The following definitions shall be added to Section One of the
     Agreement.

          SECURE HORIZONS POINT-OF-SERVICE PLAN - is a Secure Horizons Health
     Plan under which Subscribers are entitled to coverage for both In-Network
     Services and Out-of-Network Services.

          CONVENTIONAL PLAN - is the Secure Horizons Health Plan which does not
     provide coverage for Out-of-Network Services.

          IN-NETWORK SERVICES - are [Health Care Services] which are (a)
     provided or arranged by IPA under the provisions set forth in the Agreement
     for coverage of Conventional Plan Subscribers; or (b) received from an
     Outside Provider following an authorization from IPA; or (c) Emergency
     Services.

          IN-NETWORK HOSPITAL SERVICES - are In-Network Services which are also
     Hospital Services and which are provided to a Secure Horizons
     Point-of-Service Plan Member.


                                          1
<PAGE>

          OUT-OF-NETWORK MEDICAL SERVICES - are the Health Care Services
     summarized in Attachment A2 obtained by Secure Horizons Point-Of-Service
     Plan Subscribers which are not provided, arranged or authorized by IPA in
     accordance with the procedures for the Conventional Secure Plan and which
     do not qualify as Emergency Services.

          OUT-OF-NETWORK HOSPITAL SERVICES - are the Health Care Services
     summarized in Attachment A1 obtained by Secure Horizons Point-Of-Service
     Plan Subscribers which are not provided, arranged or authorized by IPA in
     accordance with the procedures for the Conventional Plan, and which do not
     qualify as Emergency Services.

          OUT-OF-NETWORK SERVICES - are Out-of-Network Medical Services and
     Out-of-Network Hospital Services. IPA shall have no financial
     responsibility for Out-of-Network Services.

2.   Section 3.07.01 shall be added to read as follows:

          3.07.01 COLLECTION OF CHARGES FOR OUT-OF-NETWORK SERVICES -
     Notwithstanding anything to the contrary in Section 3.07 or elsewhere in
     the Agreement, if an IPA Member Physician or Specialist Physician provides
     Out-of-Network Services to a Secure Horizons Point-Of-Service Plan
     Subscriber, IPA shall bill PacifiCare or PacifiCare's designee for payment
     for such services and agrees to accept full reimbursement at [  **  ] of 
     the Medicare Locality Fee Schedule for Participating Providers as published
     by the Part B carrier.  Neither IPA nor its Member Physicians shall 
     encourage Subscribers to receive Medically Necessary Services from Outside
     Providers. Breach of this Section 3.07.01 shall constitute cause for 
     termination of this Agreement.

3.   Paragraph 3.31 shall be added to read as follows:

               CALIFORNIACARE Hospitals listed in Exhibit B, except (a) when
               Medically Necessary in an Emergency situation or (b) when Covered
               Medical Services are not available in a CALIFORNIACARE Hospital
               or (c) as otherwise required under Section 4.02F or (d) when
               requested to do so in writing by the Member, with the written
               understanding that admission to a hospital, other than those
               listed in Exhibit B, is not a Covered Medical Service, except as
               stated above in this Section 4.02E.

          F.   Notwithstanding Section 4.02E, for those Members that require

               to admit, or authorize the inpatient admission or outpatient

               tertiary care or because of bed unavailability in a

               non-CaliforniaCare in-area or out-of-area facility for Hospital
               Services, then until the Member is transferred to a
               CALIFORNIACARE Hospital, the PARTICIPATING MEDICAL GROUP will be
               financially responsible for care the same as if care had been
               provided in a CALIFORNIACARE Hospital, and the Non-Capitated

                    follow appropriate billing procedures.
               (2)  That the Health Professional must look only to PARTICIPATING
                    MEDICAL GROUP for payment of Covered Medical Services and
                    shall not bill the Member, except for applicable co-payments
                    and for non-Covered Medical Services.
               (3)  Primary Care Physicians who determine that a referral is
                    necessary, may issue a referral without the prior
                    authorization of PARTICIPATING MEDICAL GROUP's Utilization
                    Management Program to physicians in the following
                    specialties: Cardiology, Dermatology, Endocrinology, Ear,

                    shall review and issue an authorization or denial of a
                    request for referral within five (5) business days of
                    receipt of such request or admission to hospital.

          I.   That visits to the Member's home within the PARTICIPATING MEDICAL
               GROUP Service  Area, by a Primary Care Physician, shall occur as
               necessary within that Physician's discretion.

               CalCare Comp provider network, whichever is applicable. In the
               event that PARTICIPATING MEDICAL GROUP elects to treat such
               Member, PARTICIPATING MEDICAL GROUP shall complete a Doctor's
               First Report of Injury as defined in the California Labor Code.
               As payment for such medical services rendered, PARTICIPATING
               MEDICAL GROUP agrees to accept, as payment in full, compensation
               in accordance with the fee schedule set forth in Exhibit E of the
               Agreement (incorporated by reference herein). PARTICIPATING
               MEDICAL GROUP further agrees that, in the event such Member
               requires medical services in connection with such work-related
               illness or injury beyond the treatment provided at the initial
               visit, PARTICIPATING MEDICAL GROUP shall refer such Member only
               to a provider that participates in the Prudent Buyer Comp
               provider network or the CalCare Comp provider network, whichever
               is applicable.

          D.   That unless agreed to in writing by BLUE CROSS, this Agreement
               shall not apply to organized physician groups (including, but not
               limited to, Independent Practice Associations) that PARTICIPATING
               MEDICAL GROUP acquires, manages or affiliates with subsequent to
               the effective date of this Agreement.

          E.   When the BLUE CROSS Managed Care Network is utilized by an
               Affiliate or Other Payor, PARTICIPATING MEDICAL GROUP agrees to
               provide services to Covered Persons of that Affiliate or Other
               Payor in accordance with the terms of this Agreement. BLUE CROSS
               shall compensate PARTICIPATING MEDICAL GROUP in accordance with
               the terms of this Agreement for services provided to Covered
               Persons of any such Other Payor. When an Other Payor utilizes the
               Managed Care Network, such Other Payor shall comply with the
               terms of this Agreement.

               In the event the BLUE CROSS Managed Care Network is to be
               utilized by an Other Payor that has operational requirements that
               are materially different from those required under this
               Agreement, BLUE CROSS agrees to notify PARTICIPATING MEDICAL
               GROUP in writing thirty (30) days prior to the commencement of
               such utilization. PARTICIPATING MEDICAL GROUP may decline to
               provide services to such Other Payor by providing written notice
               of such decision to BLUE CROSS within ten (10) days of receipt of
               notice by BLUE CROSS referenced above.

  5.07    To undertake reasonable efforts, in accordance with a standard of good
          faith, to assure that Members assigned to PARTICIPATING MEDICAL GROUP
          will live or work within the Service Area defined in this Agreement.
          However, BLUE CROSS reserves the right to assign any Members to
          PARTICIPATING MEDICAL GROUP at the Member's open enrollment period, or
          when the Member changes residence, or when BLUE CROSS determines such
          transfer to be in the Member's best interest due to special
          circumstances under the terms of the Member's Benefit Agreement.

  5.08    To exercise reasonable efforts to negotiate special rates with
          hospitals and other providers who contract with BLUE CROSS to render

  5.09    To notify and consult with PARTICIPATING MEDICAL GROUP with respect to

          withheld by PARTICIPATING MEDICAL GROUP, so long as Capitation

          services which may be required due to any amendment or change in
          Member benefits.

  5.10    To accept sole responsibility for filing reports, obtaining approvals,

          providing BLUE CROSS with any information and assistance reasonably
          required. PARTICIPATING MEDICAL GROUP is not required to provide
          information which is confidential in any other existing contract of
          PARTICIPATING MEDICAL GROUP.


                                    18

  5.11    That nothing contained in this Agreement is intended to interfere with
          the professional relationship between any Member and the Member's
          PARTICIPATING MEDICAL GROUP Physician(s).

  5.12    To collect, or arrange to have collected, all premiums, Member
          payments and other items of income to which BLUE CROSS is entitled

          be collected by PARTICIPATING MEDICAL GROUP under the conditions set
          forth in the Member's Benefit Agreement, and (d) third party liability
          payments for professional services. Pursuant to the Benefit
          Agreement(s) BLUE CROSS may hold a lien on third party liability
          payments in the amount of benefits paid by BLUE CROSS and the value of
          medical care provided under CALIFORNIACARE for the treatment of the
          illness, injury or condition for which a third party is liable. BLUE
          CROSS shall assign to PARTICIPATING MEDICAL GROUP that portion of any
          such lien related to professional services rendered under this
          Agreement by PARTICIPATING MEDICAL GROUP. PARTICIPATING MEDICAL
          GROUP's methods of collection of such payments shall be conducted in a
          reasonable and nonegregious manner and only proper legal procedures
          may be used to enforce such payment.

  5.13    To consult with PARTICIPATING MEDICAL GROUP regarding any material
          changes, as determined by BLUE CROSS, in operating procedures and

          policy and procedural changes which may have a substantial impact on
          PARTICIPATING MEDICAL GROUP.

VI.       ELIGIBILITY LISTINGS

  6.01    Eligibility listings of Members of employer groups who have personally
          selected, or been assigned to, PARTICIPATING MEDICAL GROUP shall be
          provided in the following manner:

          A.   BLUE CROSS shall maintain, update and distribute monthly, Member
               Eligibility Reports listing the persons who are eligible to
               receive Covered Medical Services during the applicable month.

          B.   PARTICIPATING MEDICAL GROUP shall receive a copy of the 
               Eligibility Reports at PARTICIPATING MEDICAL GROUP's main 
               site. Should PARTICIPATING MEDICAL GROUP request reports in 
               an electronic format, paper reports will continue to be 
               provided for an additional ninety (90) days only. As 
               described in the Operations Manual, BLUE CROSS will charge a 
               fee of between [  **  ] and [  **  ] per report, for each of 
               the following:

               (1)  duplicate copies of paper reports,
               (2)  copies of paper reports delivered in addition to reports in
                    electronic format after the ninety (90) day parallel
                    reporting period (tape, diskette, NDM or other electronic
                    medium),
               (3)  duplicate reports for prior months.

          C.   BLUE CROSS will discourage retroactive cancellation by an
               employer group of more than ninety (90) days from BLUE CROSS'
               applicable monthly billing process date. However, when no
               services have been rendered, BLUE CROSS may make occasional
               exceptions due to legitimate administrative processing
               requirements. Notwithstanding any retroactive cancellation of a
               Member by an employer group of more than ninety (90) days, BLUE


                                       19

<PAGE>

               CROSS shall not be entitled to any refund of Capitation payments
               made for such Member beyond the ninety (90) day period. BLUE
               CROSS will attempt to discourage retroactively adding any Member
               after the applicable billing is reconciled. In the event BLUE
               CROSS finds it necessary to assign, up to ninety (90) days
               retroactively, a new Member to PARTICIPATING MEDICAL GROUP,
               Capitation payment for that Member shall be made, and
               PARTICIPATING MEDICAL GROUP agrees to be responsible for all
               Covered Medical Services due that Member under the terms of the
               Member's Benefit Agreement which were provided or arranged by
               PARTICIPATING MEDICAL GROUP, from the date the Member was
               assigned.

          D.   In the event care is provided to an ineligible person, based on
               an erroneous or delayed Eligibility Report, BLUE CROSS shall be
               financially responsible for all care provided by PARTICIPATING
               MEDICAL GROUP prior to the time PARTICIPATING MEDICAL GROUP
               received notice of that person's ineligibility and, on the
               condition that PARTICIPATING MEDICAL GROUP shall supply BLUE
               CROSS with evidence that PARTICIPATING MEDICAL GROUP has
               unsuccessfully sought payment for all or a portion of the charges
               from the ineligible person, or the person having legal
               responsibility for the ineligible person, through two billing
               cycles, or through a period of sixty (60) days, whichever is
               greater. In that event, BLUE CROSS' responsibility for physician
               compensation shall be measured as set forth in Exhibit E or the
               actual billed amount, whichever is less. The obligations of BLUE
               CROSS unclear this Subsection D shall be conditioned upon the
               exercise of prudent judgment by PARTICIPATING MEDICAL GROUP,
               evidenced by reasonable efforts to contact BLUE CROSS for
               verification of the eligibility of each Member prior to providing
               or arranging Covered Medical Services.

VII.      COMPENSATION TO PARTICIPATING MEDICAL GROUP

  7.01    Exhibits D, G and G-1 (all incorporated by reference herein), set
          forth Capitation payments for new and renewing business. The
          applicable Capitation payment for each Member assigned to
          PARTICIPATING MEDICAL GROUP, shall be paid monthly, prorated in
          accordance with Member eligibility.

          Such Capitation payment shall be adjusted for Member age, sex and
          Benefit Agreement in accordance with age, sex and plan relativities
          that have been developed by BLUE CROSS based upon actuarial
          assumptions and BLUE CROSS' utilization experience. BLUE CROSS
          reserves the right to adjust such relativity factors, upon contract
          renewal, based upon BLUE CROSS' experience.

  7.02    Capitation shall be paid in consideration for providing Capitation
          Services and arranging NonCapitated Services for each Member assigned
          to PARTICIPATING MEDICAL GROUP, and in consideration for all
          Capitation Services arranged through referral for Members by
          PARTICIPATING MEDICAL GROUP. The Capitation payment shall be made by
          the tenth of each month and shall be computed on the basis of the most
          current group and individual information available. In the event that
          an error is made in the computation of the Capitation payment,
          resulting in an overpayment or underpayment to PARTICIPATING MEDICAL
          GROUP, BLUE CROSS reserves the right to adjust subsequent Capitation
          payments to PARTICIPATING MEDICAL GROUP to offset such overpayment or
          underpayment.

          Each Capitation payment shall be accompanied by a remittance summary.
          The remittance summary identifies the total Capitation amount payable,
          including retroactivity and identifies those Members whose
          retroactivity had a financial impact on the total Capitation payment.
          A complete listing of Members that are eligible for Capitation
          Services is provided in the monthly Eligibility Report, as set forth
          in Article VI.


                                       20

<PAGE>

  7.03    PARTICIPATING MEDICAL GROUP agrees that in no event shall any
          allowable co-payment or reimbursement amount, or sum thereof, due
          PARTICIPATING MEDICAL GROUP, exceed the cost to PARTICIPATING MEDICAL
          GROUP of providing the service or item which was billed.

  7.04    PARTICIPATING MEDICAL GROUP agrees to continue to provide or arrange
          for all Covered Medical Services and benefits to any Member, or former
          Member, who is eligible for coverage under the Extension of Benefits
          provision of the Benefit Agreements, in exchange for the then current
          Capitation amount per Member per month of the Benefit Agreement type
          under which the Member is, or was, enrolled. Under the circumstances
          described in this Section 7.04 BLUE CROSS shall be financially
          responsible for Non-Capitated Services.

  7.05    PARTICIPATING MEDICAL GROUP agrees to be responsible for professional
          and technical charges, as described in Exhibit A-1 (incorporated by
          reference herein), for laboratory, radiology and diagnostic testing
          procedures and diagnostic imaging examinations rendered to Members, as
          a part of, and concurrent with benefits set forth in this Agreement,
          whether billed by the hospital or by a qualified health professional

  7.06    In the event a referral provider has not been reimbursed for
          authorized Referral Services or that any other provider has not been
          reimbursed by PARTICIPATING MEDICAL GROUP as required under their
          agreement for services provided to Members within forty-five (45)
          working days following receipt of a clean, undisputed claim, then
          after notice BLUE CROSS shall have the option to pay a clean and
          uncontested claim and deduct such payment (including any interest
          payable under Health & Safety Code Section 1371), plus an
          administrative charge equal to [  **  ] of the claim amount,
          from any money due from BLUE CROSS to PARTICIPATING MEDICAL GROUP. If
          a total of five (5) or more instances occur where any provider
          associated with PARTICIPATING MEDICAL GROUP bills a Member in
          violation of this Agreement during any calendar year, BLUE CROSS may,
          in its sole discretion, suspend the assignment of new Members to
          PARTICIPATING MEDICAL GROUP until such time as PARTICIPATING MEDICAL
          GROUP has rectified the problem to BLUE CROSS' satisfaction.

VIII.     ENROLLMENT PROTECTION

  8.01    Enrollment Protection is a program designed to limit PARTICIPATING
          MEDICAL GROUP's liability for Capitation Services expense.

  8.02    For PARTICIPATING MEDICAL GROUPs with less than [  **  ] Members, on 
          the effective date of this Agreement, the liability of PARTICIPATING 
          MEDICAL GROUP for expenses for Capitation Services rendered to any 
          single Member during the calendar year shall be limited to the first 
          [  **  ] of such expenses.

  8.03    If PARTICIPATING MEDICAL GROUP's assigned CALIFORNIACARE and BLUE
          CROSS PLUS enrollment is [  **  ] or more Members, on the effective 
          date of this Agreement, PARTICIPATING MEDICAL GROUP agrees to accept 
          risk under either Subsection A or Subsection B, as indicated below.

          A.   The liability of PARTICIPATING MEDICAL GROUP for expenses for
               Capitation Services rendered to any single Member during the
               calendar year, shall be limited to the first [  **  ] of 
               Capitation Services expenses, which have been incurred by 
               PARTICIPATING MEDICAL GROUP for that Member, or


                                       21

<PAGE>

          B.   The liability of PARTICIPATING MEDICAL GROUP for expenses for
               Capitation Services rendered to any single Member during the
               calendar year, shall be limited to the first [  **  ] of 
               Capitation Services expenses which have been incurred by 
               PARTICIPATING MEDICAL GROUP for that Member.

               PARTICIPATING MEDICAL GROUP hereby elects to accept risk pursuant
               to Section 8.03. 
               / / A.  / / B. (Check one).

  8.04    Notwithstanding Section 8.02 or 8.03 above, the liability of
          PARTICIPATING MEDICAL GROUP for expenses for Capitation Services for
          Members who have been diagnosed as having Acquired Immune Deficiency
          Syndrome (AIDS) shall be limited to [  **  ] for any Member who has 
          been diagnosed as having AIDS according to the most current criteria 
          established by the Center for Disease Control (CDC) at the time of 
          the diagnosis.

  8.05    The total expenses of PARTICIPATING MEDICAL GROUP for Capitation
          Services rendered to any single Member during the calendar year shall
          be calculated according to the fee schedule set forth in Exhibit E. In
          the event the foregoing calculation for any given procedure results in
          a figure greater than the actual cost of the procedure as billed by a
          third party, then the actual cost for that procedure shall be deemed
          to be the amount actually paid by PARTICIPATING MEDICAL GROUP.

  8.06    Expenses in connection with the following services shall not be
          included as Capitation Services expenses incurred by PARTICIPATING
          MEDICAL GROUP in reaching the Enrollment Protection level:

          A.   Services rendered in connection with Workers' Compensation cases.

          B.   Services for which payment is obtained from third-party sources.

          C.   Services for which payment is obtained from BLUE CROSS through
               any coverage other than CALIFORNIACARE.

          All co-payments applicable to Capitation Services rendered to Members
          shall be subtracted from Capitation Services expenses. When the
          PARTICIPATING MEDICAL GROUP is capitated by two coverages for one
          Member, the PARTICIPATING MEDICAL GROUP agrees to coordinate all
          related co-payments under the Coordination of Benefits rules in the
          Member's Benefit Agreement.

  8.07    PARTICIPATING MEDICAL GROUP shall maintain records necessary to
          evidence having reached the Enrollment Protection level. After
          reaching the Enrollment Protection level with regard to any Member,
          during the remainder of the calendar year PARTICIPATING MEDICAL GROUP
          shall bill BLUE CROSS for [  **  ] of services rendered, or provided, 
          to that Member by PARTICIPATING MEDICAL GROUP, calculated in 
          accordance with Sections 8.02, 8.03, 8.04, 8.05 and 8.06. 
          Reimbursement to PARTICIPATING MEDICAL GROUP for Enrollment 
          Protection shall be made by BLUE CROSS in accordance with the lesser
          of actual billed charges or the fee schedule set forth in Exhibit E,
          on a monthly basis, within forty-five (45) working days of submission
          of complete and accurate documentation by PARTICIPATING MEDICAL GROUP.
          Services which are not set forth in Exhibit E shall be reimbursed by
          BLUE CROSS at the actual charges paid by PARTICIPATING MEDICAL GROUP.


                                       22

<PAGE>

  8.08    PARTICIPATING MEDICAL GROUP and BLUE CROSS acknowledge and agree that
          PARTICIPATING MEDICAL GROUP limitations of liability as set forth in
          this Article VIII shall be conditioned upon submission of clean
          undisputed claims to BLUE CROSS no later than twelve (12) months after
          the date of the service rendered to Members. Any claims under the
          Enrollment Protection program which would otherwise be the
          responsibility of BLUE CROSS under this Agreement shall be the
          financial responsibility of PARTICIPATING MEDICAL GROUP if a clean
          undisputed claim is not submitted within twelve (12) months of the
          date of service. For the purpose of this Agreement, a clean claim
          shall mean a claim that meets all BLUE CROSS requirements with respect
          to back-up information.

IX.       NON-CAPITATED SERVICES

  9.01    Non-Capitated Services, as defined in this Article, shall include
          Covered Medical Services, as set forth in the applicable Benefit
          Agreement and as authorized or referred by PARTICIPATING MEDICAL
          GROUP.

          The Covered Medical Services encompassed in Non-Capitated Services are
          delineated in Exhibit A(1) and include, but are not limited to:

          A.   Inpatient Hospital Services (exclusive of professional charges).

  9.02    Billing for Non-Capitated Services shall be as follows:

          A.   The provider of Non-Capitated Services may bill BLUE CROSS
               directly, in which case, BLUE CROSS shall reimburse said provider
               within forty-five (45) working days following receipt of a clean 
               undisputed claim accompanied by an authorization from
               PARTICIPATING MEDICAL GROUP; or,

          B.   The provider of Non-Capitated Services may bill PARTICIPATING
               MEDICAL GROUP, in which case, PARTICIPATING MEDICAL GROUP shall
               bill BLUE CROSS for reimbursement. BLUE CROSS shall reimburse
               PARTICIPATING MEDICAL GROUP within forty-five (45) working days
               following BLUE CROSS's receipt of a clean undisputed claim from
               PARTICIPATING MEDICAL GROUP, on the condition that such claim
               shall be submitted to BLUE CROSS no later than twelve (12) months
               after the date of service. This section shall only apply for the
               following Non-Capitated Services: mammography services, DME,
               prosthetics and injectable medications (including chemotherapy
               drugs and infused substances).

               In either case described above, BLUE CROSS shall pay contracting
               providers at the rate negotiated between BLUE CROSS and said
               provider. In the case of non-contracting providers, BLUE CROSS
               shall pay the lesser of: the actual billed charges, or the
               maximum allowable rate according to the BLUE CROSS Customary and
               Reasonable charges, or the rate arranged for by a CALIFORNIACARE
               Case Manager.

  9.03    Case Management Stop-Loss.

          A.   The Case Management Program is a program in which a Member's
               medical needs are assessed by PARTICIPATING MEDICAL GROUP in
               conjunction with a CALIFORNIACARE Case Manager to explore and
               coordinate treatment alternatives. PARTICIPATING MEDICAL GROUP
               should notify the CALIFORNIACARE Case Manager prior to the Member
               achieving the applicable Case Management Stop-Loss Threshold, as
               described below.

          B.   For PARTICIPATING MEDICAL GROUPs with enrollment of [  **  ] or 
               more Member Months for the calendar year, the Case Management 
               Stop-Loss Threshold for an individual Member shall be [  **  ] 
               of Non-Capitated Expenses.

               For PARTICIPATING MEDICAL GROUPs with enrollment of less than
               [  **  ] Member Months, the Case Management Stop-Loss Threshold 
               shall be [  **  ] of Non-Capitated Expenses.

          C.   Authorized expenses for Member's Non-Capitated Services, up to
               the Case Management Stop-Loss Threshold specified above will be
               accrued toward PARTICIPATING MEDICAL GROUP's PMPM Non-Capitated
               Expenses. Additionally, [  **  ] of expenses between the
               applicable Case Management Stop-loss Threshold and [  **  ] 
               incurred by an individual Member will be accrued toward 
               PARTICIPATING MEDICAL GROUP's PMPM Non-Capitated Expenses. 
               Non-Capitated expenses greater than [  **  ] for any individual
               Member will not be included in PARTICIPATING MEDICAL GROUP's PMPM
               Non-Capitated Expenses.


                                       24

<PAGE>

          D.   The Case Management Stop-loss Thresholds described above will
               apply to Members whose treatment includes transplants (solid
               organ and bone marrow/stem cell), except in those cases where
               PARTICIPATING MEDICAL GROUP fails to notify BLUE CROSS, as
               described in Section 4.02F. When PARTICIPATING MEDICAL GROUP
               fails to provide such notice, all of that Member's Non-Capitated
               Expenses will be included in PARTICIPATING MEDICAL GROUP's PMPM
               Non-Capitated Expenses.

  9.04    Calculating PARTICIPATING MEDICAL GROUP PMPM Non-Capitated Expenses.

          The Non-Capitated Expenses shall include actual expenses incurred by
          BLUE CROSS to provide Non-Capitated Services to Members, as authorized
          or referred by the PARTICIPATING MEDICAL GROUP. Expenses above the
          Case Management Stop-Loss Threshold, as set forth in Section 9.03, and
          expenses incurred by Members or former Members covered under the
          Extension of Benefits provision of the Benefit Agreements are excluded
          from PARTICIPATING MEDICAL GROUP's Non-Capitated Expenses for purposes
          of determining the Non-Capitated Performance Settlement.

          BLUE CROSS shall accrue Non-Capitated Expenses by each PARTICIPATING
          MEDICAL GROUP by the calendar year the services were incurred and paid
          through one hundred and twenty (120) days (April 30) after year-end.
          Beginning in year two (2) of this Agreement, any claims received after
          calculation of the final Non-Capitated Performance Settlement will be
          charged to the following year's Non-Capitated Expenses. Any
          Non-Capitated Services treatments that begin in one calendar year and
          extend into the next year shall accrue to the year the treatment
          began. Notwithstanding the aforementioned, any claims for
          Non-Capitated Services or Shared Risk Services (as defined in the
          CALIFORNIACARE Medical Services Agreement in effect for years prior to
          1997) paid after April 30, 1997 will be charged to the 1997
          Non-Capitated Expense.

          PARTICIPATING MEDICAL GROUP's PMPM Non-Capitated Expense is the
          quotient of PARTICIPATING MEDICAL GROUP's Non-Capitated Expenses
          divided by PARTICIPATING MEDICAL GROUP's calendar year Member Months.

          BLUE CROSS shall provide PARTICIPATING MEDICAL GROUP with quarterly
          reports advising them of their Non-Capitated Expenses. The Operations
          Manual describes the PARTICIPATING MEDICAL GROUP reports.

  9.05    Non-Capitated Performance Settlement Schedule.

          Non-Capitated Performance Settlement Schedule shall mean a schedule
          that will be the basis for determining the Non-Capitated Performance
          Settlement. This schedule presents BLUE CROSS's prior year aggregate
          PMPM Non-Capitated Expenses adjusted by factors to account for medical
          inflation. Exhibit F (incorporated by reference herein) sets forth the
          Non-Capitated Performance Settlement Schedule.

  9.06    Calculating the Non-Capitated Performance Settlement.

          A.   PARTICIPATING MEDICAL GROUP's Adjusted PMPM Non-Capitated
               Expense.

               PARTICIPATING MEDICAL GROUP's Adjusted PMPM Non-Capitated
               Expenses is the quotient of PARTICIPATING MEDICAL GROUP's PMPM
               Non-Capitated Expenses divided by the composite of PARTICIPATING
               MEDICAL GROUP's Age/Sex, Plan, Stop-Loss and Region Factors.


                                       25
<PAGE>

               The PARTICIPATING MEDICAL GROUP's PMPM Non-Capitated Expense is
               adjusted to account for the PARTICIPATING MEDICAL GROUP's mix of
               Members and make the PARTICIPATING MEDICAL GROUP's PMPM
               Non-Capitated Expenses comparable to the Non-Capitated
               Performance Settlement Schedule, as set forth in Exhibit F.

          B.   Non-Capitated Performance Settlement.

               If the PARTICIPATING MEDICAL GROUP's Adjusted PMPM Non-Capitated
               Expense is equal to or greater than the Attachment Point, the
               PARTICIPATING MEDICAL GROUP will not receive a Non-Capitated
               Performance Settlement. If the PARTICIPATING MEDICAL GROUP's
               Adjusted PMPM Non-Capitated Expense is less than the Attachment
               Point, the PARTICIPATING MEDICAL GROUP will receive a
               Non-Capitated Performance Settlement.

               The PMPM Non-Capitated Performance Settlement is determined by
               allocating a portion of the difference between the Attachment
               Point and the PARTICIPATING MEDICAL GROUP's Adjusted PMPM
               Non-Capitated Expense. The proportion of the difference allocated
               to the PMPM Non-Capitated Performance Settlement is according to
               the Non-Capitated Performance Settlement Schedule, set forth in
               Exhibit F. The PMPM Non-Capitated Performance Settlement amount
               multiplied by the PARTICIPATING MEDICAL GROUP's calendar year
               Member Months determines the total Non-Capitated Performance
               Settlement.

               Within forty-five (45) working days after April 30, BLUE CROSS
               shall pay the Non-Capitated Performance Settlement if a
               Non-Capitated Performance Settlement amount is due to the
               PARTICIPATING MEDICAL GROUP.

               Notwithstanding the above, in the event this Agreement is
               terminated, BLUE CROSS shall calculate the Non-Capitated
               Performance Settlement in accordance with this Article IX and
               shall pay PARTICIPATING MEDICAL GROUP a preliminary Non-Capitated
               Performance Settlement equal to [  **  ] of any amount due 
               PARTICIPATING MEDICAL GROUP based upon this calculation. Twelve 
               (12) months following the calculation and payment of the 
               preliminary Non-Capitated Performance Settlement, BLUE CROSS 
               shall calculate a final Non-Capitated Performance Settlement in 
               accordance with this Article IX and shall pay any amount due 
               PARTICIPATING MEDICAL GROUP, less any amounts paid at the time 
               of preliminary Non-Capitated Performance Settlement. In the 
               event monies paid PARTICIPATING MEDICAL GROUP at the time of
               the preliminary Non Capitated Performance Settlement exceed the
               final Non-Capitated Performance Settlement, PARTICIPATING MEDICAL
               GROUP shall reimburse BLUE CROSS any amounts owed within
               forty-five (45) working days of notification from BLUE CROSS.

X.        OUTPATIENT PRESCRIPTION DRUG EXPENSE

  10.01   Calculating PARTICIPATING MEDICAL GROUP PMPM Outpatient Prescription
          Drug Expenses ("PMPM OPDE").

          The Outpatient Prescription Drug Expense ("OPDE") shall include
          expenses incurred by BLUE CROSS to provide covered outpatient
          prescription drugs to Members assigned to PARTICIPATING MEDICAL GROUP.

          BLUE CROSS shall accrue OPDE for each PARTICIPATING MEDICAL GROUP by
          the calendar year the services were incurred and paid through one
          hundred and twenty (120) days after yearend. Beginning in year two (2)
          of this Agreement, any claims received after calculation of the final
          Outpatient Prescription Drug Settlement will be charged to the
          following year's OPDE. Notwithstanding the aforementioned, any claims
          for outpatient prescription drug services


                                       26
<PAGE>

          incurred prior to 1997 but paid after the final Non-Capitated
          Performance Settlement calculation for 1996 and if applicable, for
          subsequent years, will be charged to the following year's OPDE.

          PARTICIPATING MEDICAL GROUP's PMPM OPDE is the quotient of
          PARTICIPATING MEDICAL GROUP's OPDE divided by the PARTICIPATING
          MEDICAL GROUP's calendar year Member Months for Members with
          outpatient prescription drug benefits.

          BLUE CROSS shall provide PARTICIPATING MEDICAL GROUP with quarterly
          reports advising them of their OPDE. Report formats are described in
          the Operations Manual.

  10.02   Outpatient Prescription Drug Settlement Schedule.

          The Outpatient Prescription Drug Settlement Schedule set forth at
          Exhibit H (incorporated by reference herein) will be the basis for
          determining PARTICIPATING MEDICAL GROUP's Outpatient Prescription Drug
          Settlement.

  10.03   Calculating the Outpatient Prescription Drug Settlement.

          If PARTICIPATING MEDICAL GROUP's PMPM OPDE is less than the Outpatient
          Prescription Drug Expense Target, the PARTICIPATING MEDICAL GROUP will
          receive an Outpatient Prescription Drug Settlement. If the
          PARTICIPATING MEDICAL GROUP's PMPM Outpatient Prescription Drug
          Expense is equal to or greater than the Outpatient Prescription Drug
          Expense Target, the PARTICIPATING MEDICAL GROUP will not receive an
          Outpatient Prescription Drug Settlement.

          A.   Outpatient Prescription Drug Settlement.

               The PMPM Outpatient Prescription Drug Settlement is determined by
               allocating a portion of the difference between the OPDE Target,
               and the PARTICIPATING MEDICAL GROUP's PMPM Outpatient
               Prescription Drug Expense. The proportion of the difference
               allocated to the PMPM Outpatient Prescription Drug Settlement is
               determined in accordance with the Outpatient Prescription Drug
               Schedule, set forth in Exhibit H.

          B.   Formulary Utilization Incentive.

               If PARTICIPATING MEDICAL GROUP's use of the BLUE CROSS Outpatient
               Prescription Drug Formulary (the "Formulary") is equal to or
               greater than [  **  ], as described in Exhibit H, and 
               PARTICIPATING MEDICAL GROUP's PMPM OPDE is less than the OPDE 
               Target, an additional [  **  ] PMPM will be added to
               PARTICIPATING MEDICAL GROUP's PMPM Outpatient Prescription Drug
               Settlement.

          The amount of the Outpatient Prescription Drug Settlement and
          Formulary utilization incentive will be based on the applicable PMPM
          Settlement calculation under Exhibit H multiplied by PARTICIPATING
          MEDICAL GROUP's Member Months for Members with outpatient prescription
          drug benefits. Within forty-five (45) working days after April 30,
          BLUE CROSS will pay any Outpatient Prescription Drug Settlement that
          is due PARTICIPATING MEDICAL GROUP for the previous year.

          Notwithstanding the above, in the event this Agreement is terminated
          BLUE CROSS shall calculate the Outpatient Prescription Drug Settlement
          in accordance with this Article X and shall pay PARTICIPATING MEDICAL
          GROUP a preliminary Outpatient Prescription Drug Settlement equal to
          [  **  ] of any amount due PARTICIPATING MEDICAL GROUP based upon 
          this calculation. Twelve (12) months following the calculation and 
          payment of the preliminary Outpatient Prescription Drug Settlement, 
          BLUE CROSS shall calculate a final


                                       27
<PAGE>

          Outpatient Prescription Drug Settlement in accordance with this
          Article X and shall pay any amount due PARTICIPATING MEDICAL GROUP.
          less any amounts paid at the time of preliminary Outpatient
          Prescription Drug Settlement. In the event monies paid PARTICIPATING
          MEDICAL GROUP at the time of the preliminary Outpatient Prescription
          Drug Settlement exceed the final Outpatient Prescription Drug
          Settlement, PARTICIPATING MEDICAL GROUP shall reimburse BLUE CROSS any
          amounts owed within forty-five (45) working days of notification from
          BLUE CROSS.

XI.       QUALITY MANAGEMENT BONUS

          Blue Cross will evaluate PARTICIPATING MEDICAL GROUP's Quality
          Management Program and Member quality of care using a scorecard.
          PARTICIPATING MEDICAL GROUP will be notified of the scorecard
          parameters and scoring methodology prior to the start of each year, as
          described in the Operations Manual.

          PARTICIPATING MEDICAL GROUP must meet minimum eligibility criteria to
          receive a scorecard score and therefore to be eligible for a Quality
          Management Bonus. These criteria include a minimum of [  **  ] Member
          months for a calendar year and submission to BLUE CROSS of all
          necessary encounter data.

          A Quality Management Bonus will be paid if PARTICIPATING MEDICAL
          GROUP's performance on the scorecard is average or above average. No
          Quality Management Bonus will be paid if PARTICIPATING MEDICAL GROUP's
          scorecard performance is below average. BLUE CROSS will notify
          PARTICIPATING MEDICAL GROUP of the scorecard results sixty (60) days
          following the end of the calendar year.

          The Quality Management Bonus paid to PARTICIPATING MEDICAL GROUP,
          should a payment be due in accordance with the PMPM Quality Management
          Bonus Schedule shown in Exhibit I (incorporated by reference herein),
          will be made by the fifteenth of June following the end of the
          calendar year for which it is based.

XII.      BILLING FOR HMO-USA AWAY FROM HOME CARE SERVICES

  12.01   PARTICIPATING MEDICAL GROUP agrees to render or refer urgent care,
          Emergency services, follow-up care and routine services, as Host HMO
          to out-of-state members of HMO-USA participating plans, when such care
          is prearranged by BLUE CROSS. Urgent care as it relates to the HMO-USA
          Away From Home Care Program means outpatient medical care which the
          Host HMO determines is required for an unexpected illness or injury
          that is not life threatening, but which cannot reasonably be postponed
          until the HMO-USA participating plan member returns to the service
          area of the member's Home HMO.

          All medical services rendered at PARTICIPATING MEDICAL GROUP or
          Satellite Facilities and all Referral Services rendered to members of
          HMO-USA participating plans, due to unavailability of the required
          services at PARTICIPATING MEDICAL GROUP, shall be paid by BLUE CROSS.
          For services PARTICIPATING MEDICAL GROUP provides directly to members
          of HMO-USA participating plans, BLUE CROSS shall reimburse
          PARTICIPATING MEDICAL GROUP at PARTICIPATING MEDICAL GROUP's invoiced
          amount, not to exceed reimbursement in accordance with Exhibit E of
          this Agreement. For Referral Services, PARTICIPATING MEDICAL GROUP may
          instruct providers of Referral Services to bill BLUE CROSS directly
          or, such providers may bill PARTICIPATING MEDICAL GROUP, in which
          case, PARTICIPATING MEDICAL GROUP shall be reimbursed by BLUE CROSS.
          In all cases, PARTICIPATING MEDICAL GROUP or provider of Referral
          Services shall note on the claim that services were


                                       28
<PAGE>

          rendered to a member of an HMO-USA participating plan. Neither
          PARTICIPATING MEDICAL GROUP nor provider of Referral Services shall
          bill members of HMO-USA participating plans.

  12.02   BLUE CROSS agrees to pay PARTICIPATING MEDICAL GROUP within forty-five
          (45) working days of receipt of a completed professional services
          claim form for authorized services rendered to members of HMO-USA
          participating plans.

XIII.     TERM OF AGREEMENT, TERMINATION

  13.01   This Agreement shall be in effect for a THREE (3) year period (the
          "Initial Term") from the date noted on page 1. Unless written notice
          of intent not to renew or of intent to modify this Agreement is
          provided at least one hundred twenty (120) days prior to completion of
          the Initial Term or any subsequent renewal period, this Agreement
          shall renew upon the same terms and conditions for consecutive one
          year periods each year thereafter.

  13.02   Should this Agreement be terminated pursuant to Section 13.01 above,
          PARTICIPATING MEDICAL GROUP agrees to continue to provide Capitation
          Services and to arrange NonCapitated Services for all Members assigned
          to PARTICIPATING MEDICAL GROUP, including any Members who become
          eligible during the notice period set forth in Section 13.01 above;
          and to provide these services consistent with the terms and conditions
          of the applicable Benefit Agreements. In such case, Capitation
          Services rendered to Members shall be compensated at the applicable
          rates set forth in Exhibit E, until the annual anniversary dates of
          the Benefit Agreements of Members assigned to PARTICIPATING MEDICAL
          GROUP.

          In the event this Agreement is terminated, BLUE CROSS shall have the
          right, but not the obligation, to directly pay any bills for expenses
          for Referral Services rendered to Members assigned to PARTICIPATING
          MEDICAL GROUP which remain outstanding on the date of termination.
          BLUE CROSS shall immediately be notified in writing of all such
          outstanding bills for Referral Services and BLUE CROSS shall have the
          right to set off the amount of such payments against any amount due
          PARTICIPATING MEDICAL GROUP for Capitation and NonCapitated Services
          pursuant to Article IX, or any other payments due PARTICIPATING
          MEDICAL GROUP.

          The right to set off such payments against any amounts due under this
          Agreement shall be in addition to any other rights BLUE CROSS may have
          under this Agreement, or in law or in equity.

  13.03   Termination of this Agreement shall not affect any rights or
          obligations hereunder which shall have previously accrued, or shall
          thereafter arise, with respect to any occurrence prior to termination,

XIV.      ARBITRATION OF DISPUTES BETWEEN BLUE CROSS AND PARTICIPATING MEDICAL
          GROUP

  14.01   PARTICIPATING MEDICAL GROUP and BLUE CROSS agree to meet and confer in
          good faith to resolve any problems or disputes that may arise under
          this Agreement.

  14.02   Any problem or dispute arising under this Agreement and/or concerning
          the terms of this Agreement that is not satisfactorily resolved under
          Section 14.01 shall be arbitrated. The arbitration shall be initiated
          by either party making a written demand for arbitration on the other
          party. Arbitration shall be conducted by the American Arbitration
          Association (AAA) under the Commercial Rules of the AAA. The
          arbitration shall also be subject to California Code of Civil
          Procedure, Title Nine, Section 1280, ET. SEQ., unless otherwise
          mutually agreed. The parties agree that the decision of the arbitrator
          shall be final and binding as to each of them, except to the extent
          that California or Federal law provide for the review of arbitration
          proceedings. Issues as to whether malpractice was committed by a
          physician shall not be subject to Arbitration by the AAA unless
          otherwise agreed in writing by the parties and the AAA.

  14.03   ARBITRATION FEE. In all cases submitted to AAA, the parties agree to
          share equally the AAA administrative fee as well as the arbitrator's
          fee, if any, unless otherwise assessed by the arbitrator. The
          administrative fee shall be advanced by the initiating party.

  14.04   ENFORCEMENT OF AWARD. The parties agree that the arbitrator's award
          may be enforced in any court having jurisdiction thereof by the filing
          of a petition to enforce said award. Costs of filing may be recovered
          by the party that initiates the action to have an award enforced.

  14.05   ALTERNATIVE DISPUTE SETTLEMENT TECHNIQUES. Should the parties, prior
          to submitting a dispute to arbitration, desire to utilize other
          impartial dispute settlement techniques, such as mediation or
          fact-finding, a joint request for such services may be made to the
          AAA, or the parties may initiate such other procedures as they may
          mutually agree upon.

  14.06   LIMITATION. Nothing contained herein is intended to create, nor shall
          it be construed to create, any right of any Member to independently
          initiate the arbitration procedure established in this Article. This
          limitation shall not prevent BLUE CROSS from initiating such
          procedures as the representative of its Members, or PARTICIPATING
          MEDICAL GROUP from initiating such procedures on behalf of Members for
          whom they have assumed responsibility for the provision of Capitation
          Services, and for arranging Non-Capitated Services provided that in
          any such case BLUE CROSS or PARTICIPATING MEDICAL GROUP, respectively,
          shall be considered the initiating party for the purposes of Section
          14.03 hereof.

  14.07   Each party hereto agrees to notify the other at the earliest
          reasonable time in the event of any dispute which may be arbitrated,
          and in the event either party becomes aware of facts or circumstances
          which indicate a reasonable possibility of litigation with any third
          person or entity, and which are relevant to any rights, obligations,
          or other responsibilities under this Agreement.

values based on observed charge patterns by CPT-4 procedure code. The maximum 
allowable for physician claims shall be calculated using the unit values as 
in effect, multiplied by the following conversion factors: *

     by BLUE CROSS, a handling fee of [  **  ] per OCR scannable claim and 
     [  **  ] per paper claim will be deducted from payment due PHYSICIAN. 
     PHYSICIAN will not charge Members for the handling fee.

                       REIMBURSEMENT FOR HCPCS LEVEL II CODES

PHARMACY (INCLUDING INFUSION THERAPY DRUGS): Maximum Allowable reimbursement 
based on Average Wholesale Price (AWP) according to published market data 
(such as DRUG TOPICS RED BOOK, AMERICAN DRUGGIST BLUE BOOK, OR MEDISPAN). 
Oral prescription drugs dispensed in the physician's office will be denied as 
not payable, and the Member may not be billed by physician.

DURABLE MEDICAL EQUIPMENT, SUPPLIES (INCLUDING, BUT NOT LIMITED TO, INFUSION 
THERAPY SUPPLIES), PROSTHETICS AND ORTHOTICS: Maximum Allowable Reimbursement 
not to exceed the lesser of the average retail price or the Medicare regional 
allowable reimbursement rates applied to California for the appropriate code 
ranges. The average retail price will be determined annually from claims data 
and/or external data. Reimbursement rates will be based on whether the 
equipment is new, used or rented as identified by the CPT code modifier. 
Codes not identified by modifier will be considered as rentals.

ALL OTHER HCPCS CODES: For all other HCPCS codes the Maximum Allowable will 
be determined by Blue Cross using claims data and/or external data.

                   NON-CAPITATED PERFORMANCE SETTLEMENT SCHEDULE
                         FOR NON-CAPITATED MEDICAL SERVICES

                        Based on Plan C, $60,000 Stop Loss, 
                  Age/Sex Factor = 1.00 and Regional Factor = 1.00

NON-CAPITATED PERFORMANCE SETTLEMENT CALCULATION METHOD:

1)   Identify the payment band that contains the PARTICIPATING MEDICAL GROUP's
     Adjusted PMPM Non-Capitated Expense
2)   Subtract the PARTICIPATING MEDICAL GROUP's PMPM Non-Capitated Expense from
     the high value of the payment band
3)   Multiply the result from Step 2 by the multiplier column for the payment
     band
4)   Add the result from Step 3 to the minimum payment amount for the payment
     band to get the PMPM Non-Capitated Performance Settlement
5)   Multiply the PMPM Non-Capitated Performance Settlement from Step 4 by the
     PARTICIPATING MEDICAL GROUP's Member Months to calculate the Non-Capitated
     Performance Settlement

Example of Non-Capitated Performance Settlement Calculation

Assume: PARTICIPATING MEDICAL GROUP has an PMPM Non-Capitated Expense of 
$26.63; and there are 100,000 member months

(1)  Identify the payment band that contains the PARTICIPATING MEDICAL GROUP's
     Adjusted PMPM Non-Capitated Expense.
     The PARTICIPATING MEDICAL GROUP's PMPM Non-Capitated Expense of $26.63
     falls between the low and high values of payment band 5
(2)  Subtract the PARTICIPATING MEDICAL GROUP's PMPM Non-Capitated Expense from
     the high value for the payment band.
     $27.63 - $26.63 = $1.00
(3)  Multiply the result from Step 2 by the multiplier for the payment band.
     $1.00 x [  **  ] = [  **  ]
(4)  Add the result from Step 3 to the minimum payment amount for the payment
     band to get the PMPM Non-Capitated Performance Settlement.
     [  **  ] + [  **  ] = [  **  ] PMPM Non-Capitated Performance Settlement
(5)  Multiply the PMPM Non-Capitated Performance Settlement from Step 4 by the
     PARTICIPATING MEDICAL GROUP's Member Months to calculate the Non-Capitated
     Performance Settlement.
     [  **  ] PMPM Non-Capitated Performance Settlement x 100,000 member months 
     = [  **  ] Non-Capitated Performance Settlement

                COMPENSATION FOR SERVICES TO BLUE CROSS PLUS MEMBERS

In consideration for the mutual promises herein set forth, PARTICIPATING MEDICAL
GROUP and BLUE CROSS hereby agree as follows:

I.   DEFINITIONS

     A.   "ADVANCE SUPPLEMENTAL CAPITATION PAYMENT" means a supplemental
          Capitation payment apportioned monthly and paid in advance of the
          date it is earned. Advance Supplemental Capitation Payments are
          subject to recoupment by BLUE CROSS if not actually earned prior to
          the end of the calendar quarter.

     B.   "BASELINE CAPITATION PAYMENT" means the monthly Capitation payment for
          each Member covered by a BLUE CROSS PLUS Benefit Agreement and
          assigned to PARTICIPATING MEDICAL GROUP.

     C.   "IN-NETWORK SERVICES" means those services which are provided,
          arranged by, referred or authorized by PARTICIPATING MEDICAL GROUP for
          BLUE CROSS PLUS Members and which would be CALIFORNIACARE Capitation
          Services if they had been rendered under the Agreement to a
          CALIFORNIACARE Member.

     D.   "IN-NETWORK UTILIZATION FACTOR" means the quotient of the Baseline
          Capitation Payment, divided by the sum of Baseline Capitation Payments
          plus expenses for Out-of-Network Services, modified each calendar
          quarter to allow for incurred but not reported expenses (IBNR) based
          on BLUE CROSS's overall BLUE CROSS PLUS experience, as follows:

          Baseline Capitation Payment                            = A

          Expenses for Out-of-Network Services                   = B  
          (Modified to allow for IBNR)

          In-Network Utilization Factor                          = C

                 A
          C = -------
               A + B

     E.   "NON-PARTICIPATING PROVIDER" means a Health Professional, hospital,
          emergency facility, skilled nursing facility, ambulance service, home
          health agency, or Alternate Birthing Center that has rendered services
          to a BLUE CROSS PLUS Member without authorization from the
          PARTICIPATING MEDICAL GROUP to which the Member is assigned.

     F.   "OUT-OF-NETWORK SERVICES" means those services rendered to BLUE CROSS
          PLUS Members by a Non-Participating Provider, and which would be
          Capitation Services if rendered by PARTICIPATING MEDICAL GROUP under
          the Agreement to CALIFORNIACARE Members, except for Out-of-Area
          Emergency Services.

     G.   "SUPPLEMENTAL CAPITATION PAYMENT" means a Capitation payment per BLUE
          CROSS PLUS Member per month, which may be earned based on the
          In-Network Utilization Factor as set forth in Exhibit G-1.

               for Medical Group Services provided to Medical Group Members
               under this Agreement.

       2.3.4   RESTRICTION, SUSPENSION OR TERMINATION OF PARTICIPATING
               PROVIDERS. Medical Group shall, as warranted, immediately
               restrict, suspend or terminate its Participating Providers from
               providing or arranging Covered Services to Medical Group Members
               in the following circumstances: (i) the Participating Provider
               ceases to meet the licensing/certification requirements or other
               professional standards described in this Agreement; (ii)
               PacifiCare or Medical Group reasonably determines that there are
               serious deficiencies in the professional competence, conduct or
               quality of care of the Participating Provider which affects or
               could adversely affect the health or safety of Medical Group
               Members; or (iii) PacifiCare reasonably demands that the
               Participating Provider be restricted, suspended or terminated.
               Medical Group shall immediately notify PacifiCare of any of its
               Participating Providers who cease to meet the
               licensing/certification requirements or other professional

               under this Section. If Medical Group fails to act as required by
               this Section with respect to any of its Participating Providers,
               PacifiCare shall have the right to immediately prohibit such
               Participating Providers from continuing to provide Covered
               Services to Medical Group Members.

       2.3.5   CHANGES IN CAPACITY. Medical Group and its Participating
               Providers will continue to accept Members enrolled by PacifiCare
               for so long as Medical Group and its Participating Providers have
               the capacity to provide and arrange Covered Services under this
               Agreement and for so long as Medical Group continues to accept
               new patients from any HMO or other prepaid health plan. Medical
               Group shall provide at least ninety (90) calendar days prior
               written notice to PacifiCare of any significant changes in the
               capacity of Medical Group to provide or arrange Covered Services
               that would prevent Medical Group from accepting additional
               Members. A significant change in capacity includes, without
               limitation, the following: (i) inability of Medical Group to
               properly serve additional Members due to a lack of Primary Care
               Physicians or other Participating Providers; (ii) inability of
               any one of Medical Group's Primary Care Physicians or other
               Participating Providers to serve additional Members; or (iii)

               enroll Members with Medical Group until the expiration of the
               notice period required under this Section, and in such event,
               Medical Group and its Primary Care Physicians and other
               Participating Providers shall continue to accept such Members.
               PacifiCare shall discontinue the enrollment of Members with

               this Section until such time, if any, that Medical Group

               (60) calendar days to be consistent with such amendments or
               modifications.

       2.4.2   COMPLIANCE WITH STANDARDS OF ACCREDITATION ORGANIZATIONS AND
               REQUIREMENTS OF STATE AND FEDERAL LAW. Medical Group's

               with Participating Providers to comply with such changes within
               thirty (30) calendar days following notice thereof from
               PacifiCare.

               and records of its Participating Providers relating to Covered
               Services provided to Medical Group Members. Unless shorter notice
               is specified by a Government Agency, PacifiCare shall provide
               Medical Group with two (2) business days prior written notice of
               any inspection, examination and copying under this Section. Any
               such inspection, examination and copying shall be conducted

               subcontracts with its Participating Providers, Medical Group
               shall remain responsible for satisfying the obligations of
               Medical Group set forth in this Agreement. If any of Medical
               Group's subcontracts with Participating Providers are terminated,

2.5    ACCEPTANCE AND TRANSFER OF MEMBERS. Medical Group and its Participating
       Providers may not impose any limitations on the acceptance of Members for
       care or treatment that are not imposed on other patients. PacifiCare,
       Medical Group and its Participating Providers shall not request, demand,
       require or seek directly or indirectly the transfer, discharge or removal
       of any Member for reasons of Member's need for, or utilization of,
       Covered Services, except in accordance with the procedures established
       for such action. Medical Group and its Participating Providers shall not
       refuse or fail to provide or arrange Covered Services to any Member.

       PacifiCare and Medical Group shall exercise reasonable efforts in
       following the procedures for transfer, discharge or removal of Members as
       set forth in the Provider Manual. Nevertheless, PacifiCare may require
       transfer of Medical Group Members for any reason, and Medical Group may
       request that PacifiCare transfer Medical Group Members to another of
       PacifiCare's Participating Providers if Medical Group is unable to
       provide Covered Services required by this Agreement for reasons related
       to capacity of Medical Group and its Participating Providers. In
       addition, Medical Group may request that PacifiCare transfer a Medical
       Group Member to another of PacifiCare's Participating Providers in the
       event of a material breakdown in the physician-patient relationship.
       PacifiCare shall evaluate such requests considering the best interests of
       the Member. In the event PacifiCare grants a request for transfer of a
       Member by Medical Group, the transfer shall not be effective until the
       end of the month following the month in which the Member receives notice
       of transfer, unless the Member agrees to an earlier transfer and
       PacifiCare has made arrangements with another of PacifiCare's
       Participating Providers to accept the Member.

2.6    MEDICAL RECORDS. Medical Group and its Participating Providers shall
       maintain all patient medical records relating to Covered Services
       provided to Members, in such form and containing such information as
       required by the QI Program, Accreditation Organizations and State and
       Federal Law. Medical records shall be maintained in a manner that is
       current, detailed, organized and permits effective patient care and
       quality review by Medical Group and PacifiCare pursuant to the QI
       Program. Medical records shall be maintained in a form and physical
       location which is accessible to Medical Group's Participating Providers,
       PacifiCare, Government Agencies and Accreditation Organizations. Upon
       reasonable request and within the time frame requested, Medical Group and
       its Participating Providers shall provide to PacifiCare, at Medical
       Group's or Participating Provider's expense, copies of Member medical   
       records for purposes of conducting quality assurance, case management and
       utilization reviews, credentialing and peer review, claims processing,
       verification and payment, resolving Member grievances and appeals and
       other activities reasonably necessary for the proper administration of
       the Managed Care Plans consistent with State and Federal Law. If Medical
       Group or its Participating Providers do not provide copies of Member
       medical records to PacifiCare within the time frame requested, Medical
       Group and its Participating Providers shall allow PacifiCare immediate
       access to such medical records for onsite copying and shall reimburse
       PacifiCare for the actual copying expense. Medical Group and its
       Participating Providers shall maintain the confidentiality of all Member
       medical records and treatment information in accordance with State
       and Federal Law. Medical records shall be retained by Medical Group and
       its Participating Providers for at least five (5) years following the
       provision of Covered Services and as required by State and Federal Law.
       The provisions of this Section shall survive termination of this
       Agreement for the period of time required by State and Federal Law.

       coverage required of Medical Group under this Section, unless otherwise
       consented to by PacifiCare in writing.

       shall provide that PacifiCare shall receive thirty (30) days prior
       written notice of cancellation or material reduction in the insurance
       coverage specified in this Section. Notwithstanding any other provision
       of this Agreement, failure to provide the certificate of insurance when

       this Agreement.

               such information and data to PacifiCare in the format and within
               the time periods specified by PacifiCare.

2.10   MEDICAL GROUP'S FAILURE TO COMPLY WITH AGREEMENT, PROVIDER MANUAL OR
       MANAGED CARE PLANS. If Medical Group fails to comply with any
       provision(s) of this Agreement, the Provider Manual or the Managed Care

       Group, specifying a date at least forty five (45) days following the date

       which Medical Group must be in compliance with such provision(s), as
       reasonably determined by PacifiCare. If Medical Group fails to comply
       with such provision(s) by the date specified in the notice, PacifiCare
       shall have the right to cease marketing efforts on behalf of Medical
       Group and/or discontinue enrollment of Members with Medical Group until
       such time as Medical Group complies with such provision(s), as reasonably
       determined by PacifiCare. In addition, PacifiCare shall have the right to
       either (i) collect from Medical Group or (ii) offset against amounts due
       Medical Group under this Agreement, any penalties or other monetary
       amounts payable by PacifiCare to Government Agencies, Subscriber Groups,
       Participating Providers or any other health care providers as a result of
       Medical Group's failure to comply with any provision(s) of this
       Agreement, the Provider Manual or Managed Care Plans. PacifiCare's rights
       and remedies under this Section shall be in addition to all other rights
       and remedies available to PacifiCare to enforce this Agreement, including
       the right of termination.

2.11   RECIPROCITY ARRANGEMENTS. If any Member who is not a Medical Group Member
       or if any individual who is enrolled in a benefit plan and program of any
       PacifiCare affiliated entity ("PacifiCare Affiliate") receives services 
       or treatment from Medical Group or its Participating Providers, Medical 
       Group or the Participating Provider agrees to bill PacifiCare or the 
       PacifiCare Affiliate (or their respective designees), as applicable, at 
       billed charges and to accept the Cost of Care amount less any applicable
       Copayments, coinsurance, and/or deductibles as payment in full for such 
       services or treatment. PacifiCare or the PacifiCare Affiliate will 
       process payment for such services or treatment in accordance with the 
       payment procedures for the applicable benefit plan or program.

       If any Medical Group Member receives Covered Services from a PacifiCare
       Participating Provider or PacifiCare Affiliate contracted provider,
       PacifiCare shall, where contractually available, provide reciprocity to
       Medical Group at PacifiCare rates for such Covered Services. Medical
       Group shall comply with the procedures established by PacifiCare or the
       PacifiCare Affiliate for reimbursement of such Covered Services.

       Only medically appropriate Covered Services, as determined by PacifiCare,
       shall be subject to the reciprocity arrangement specified in this
       Section. Medical Group shall abide by all provisions of this Agreement
       relating to non-billing of Members with respect to all services and
       treatment subject to this reciprocity arrangement.

2.12   HOSPITAL ADMISSIONS. In recognition of the need for coordination of
       Covered Services provided to Medical Group Members and to ensure
       continuity and quality of care, Medical Group agrees to utilize Hospital

       to the following exceptions:

               Needed Services;

       Notwithstanding the foregoing, Medical Group Member requests for
       treatment at another PacifiCare Participating Provider may be granted due
       to limited Hospital bed capacity or if such request is in the Member's
       best interest, as determined by PacifiCare.

               been furnished or Covered Services that should have been
               furnished have not been furnished. Upon request, PacifiCare shall

        Providers shall participate, cooperate and comply with PacifiCare's

        health services to Medical Group Members in accordance with the
        Preventive Health Guidelines.

4.1.6   MEDICAL RECORD REVIEW. PacifiCare shall on an ongoing basis review
        medical records maintained by Medical Group and its Participating

               Organizations. Medical Group and its Participating Providers
               shall maintain medical records in accordance with the provisions
               of this Agreement regarding medical records and in accordance
               with PacifiCare's guidelines regarding medical records.

        4.1.7  CLAIMS PROCESSING. PacifiCare shall establish and maintain
               standards, policies and procedures for the timely and accurate

               PacifiCare's Claims Processing Guidelines.

4.2     PERFORMANCE OF DELEGATED ACTIVITIES. As of the Commencement Date,
        PacifiCare shall delegate to Medical Group, and Medical Group shall

        Agreement relating to the following Managed Care Program Services which
        are described above: (i) Utilization Management; (ii) Credentialing;
        (iii) Claims Processing (collectively, the "Delegated Activities").

        4.2.1   PACIFICARE POLICIES. For all Delegated Activities, PacifiCare
                shall provide Medical Group with PacifiCare's standards and
                requirements applicable to the Delegated Activities, as amended
                from time to time (the "PacifiCare Policies") and shall notify  
                Medical Group of all substantive changes to the PacifiCare
                Policies. Medical Group may utilize its own policies and
                procedures for the Delegated Activities, provided that such
                policies and procedures are consistent with the PacifiCare
                Policies and are provided to PacifiCare for its review and
                approval. If Medical Group's policies and procedures are
                inconsistent with the PacifiCare Policies, the PacifiCare
                Policies shall apply.

        4.2.2   SUB-DELEGATION. Medical Group shall not further delegate the
                performance of Delegated Activities to any of its Participating
                Providers or any other organization or entity without the prior
                written consent of PacifiCare. Medical Group acknowledges  and
                agrees that PacifiCare is accountable for all Delegated
                Activities, and therefore, Medical Group and its Participating
                Providers agree to participate, cooperate and comply with
                PacifiCare with respect to all Delegated Activities.

        4.2.3   MAINTENANCE OF INFORMATION AND RECORDS. Medical Group shall
                maintain all information and records reviewed or created in
                connection with performing the Delegated Activities in a form
                acceptable to PacifiCare, provide PacifiCare with access to
                such information and records, and permit PacifiCare to review
                and copy such information and records, in accordance with the
                requirements of State and Federal Law and standards of
                Accreditation Organizations.

                written reports provided by Medical


                                          16
<PAGE>

               Group as described above and meetings with appropriate Medical
               Group representatives and on-site audits and assessments of
               Medical Group. Medical Group shall cooperate, participate and
               comply with PacifiCare in such monitoring and oversight
               activities. Such audits and assessments will be performed in
               accordance with the requirements of State and Federal Law and
               the standards of Accreditation Organizations. Without limiting
               the foregoing, Medical Group agrees that arrangements with its
               Participating Providers will permit Medical Group to disclose
               to PacifiCare its Participating Provider credentialing files.

4.3     PAYMENT FOR PERFORMANCE OF DELEGATED ACTIVITIES. Payment for
        performance of the Delegated Activities by Medical Group is included in
        Capitation Payments made to Medical Group under this Agreement. The
        following percentage points have been allocated to the performance of
        Delegated Activities:

<TABLE>
<CAPTION>

        Delegated Activity                          Percentage points
        ------------------                          -----------------
<S>                                                  <C>

        Claims Processing                                 [  **  ]
</TABLE>

        For each month in which the performance of any Delegated Activity is
        revoked by PacifiCare as provided in this Article 4, the Capitation
        Payment shall be reduced by the percentage points specified above for
        such Delegated Activity. PacifiCare may modify the payment for
        Delegated Activities effective at the beginning of any calendar year by
        providing Medical Group with sixty (60) calendar days prior written
        notice.

4.4     REVOCATION OF DELEGATED ACTIVITIES. PacifiCare may revoke any or all
        Delegated Activities if PacifiCare determines that they are not being
        performed in accordance with the standards and requirements established
        by PacifiCare or if Medical Group's performance of Delegated Activities
        is inconsistent with, or in violation of, State and Federal Law or
        threatens PacifiCare's accreditation by any Accreditation Organization.
        PacifiCare shall provide Medical Group at least thirty (30) calendar
        days prior written notice specifying the Delegated Activities which
        PacifiCare intends to revoke, unless PacifiCare determines that Medical
        Group's continued performance of Delegated Activities presents a risk
        of harm to PacifiCare Members, in which case the Delegated Activities
        shall be revoked immediately. If Medical Group does not conform to the
        applicable standards and requirements within such notice period,
        PacifiCare shall send a second written notice to Medical Group
        confirming the revocation of the Delegated Activities, the effective
        date of such revocation and the period of time such revocation shall
        remain in effect (the "Revocation Period"). During the Revocation
        Period, Medical Group shall take corrective action to conform with
        applicable standards and requirements established by PacifiCare. At the
        end of the Revocation Period, PacifiCare shall evaluate Medical Group's
        corrective action, determine whether Medical Group is able to resume
        performance of the Delegated Activities, and provide written notice to
        Medical Group of such determination.

        The written notices from PacifiCare to Medical Group under this Section
        shall specify (i) the adjustments to Capitation Payments as a result of
        the revocation of any Delegated Activities in


                                          17
<PAGE>

        accordance with the allocations set forth in this Article 4, and (ii)
        in the event that claims processing is revoked, the adjustments to
        Capitation Payments for claims payment as set forth in Section 5.2. If
        only a portion of a specific Delegated Activity is revoked (e.g.,
        Medical Group continues to perform some, but not all, of a specific
        Delegated Activity), PacifiCare shall have the right to adjust the
        allocations set forth in this Article 4 to reflect the portion of the
        specific Delegated Activity which continues to be performed by Medical
        Group. Notwithstanding any other provision of the Agreement, the
        written notices from PacifiCare to Medical Group under this Section
        shall be deemed valid and enforceable modifications to the Agreement,
        whether or not signed by Medical Group.

        Upon revocation of any of the Delegated Activities, PacifiCare will
        resume responsibility for performing such activities, and Medical Group
        and its Participating Providers shall continue to cooperate,
        participate and comply with PacifiCare with respect to the performance
        of such activities.

        Notwithstanding PacifiCare's right to revoke Delegated Activities,
        Medical Group's failure to perform the Delegated Activities shall be a
        breach of the Agreement. In such event, PacifiCare may exercise all of
        its rights and remedies to enforce the Agreement, including the right
        of termination.

                                      ARTICLE 5
                                     COMPENSATION

5.1     CAPITATION PAYMENTS. PacifiCare shall make monthly Capitation Payments
        to Medical Group as payment for providing and arranging Covered
        Services to Medical Group Members for each Managed Care Plan, as
        specified in this Agreement and the applicable Product Attachment.

        5.1.1   DUE DATE. Each Capitation Payment shall be due and payable on
                the tenth (10th) day of the month for the current month's
                Covered Services. In the event the tenth (10th) day of the
                month is not a business day, the Capitation Payment shall be
                due and payable on the next business day following the tenth
                (10th) day of the month.

        5.1.2   DOCUMENTATION. PacifiCare shall provide Medical Group
                appropriate documentation in support of each Capitation
                Payment.

        5.1.3   RETROACTIVE ADJUSTMENTS. Capitation Payments shall be subject
                to retroactive adjustments either upward or downward due to
                retroactive changes in the Premium for each Managed Care Plan
                as specified in the applicable Product Attachment and
                retroactive changes in the number of Medical Group Members for
                each Managed Care Plan. Retroactive adjustments to Capitation
                Payments for Medical Group Members enrolled in Managed Care
                Plans which are government funded (including, without
                limitation, Medicare, Medicaid, public employees) shall be made
                within thirty (30) days after the adjustment is determined.
                Retroactive adjustments to Capitation Payments for Medical
                Group Members enrolled in Managed Care Plans which are not
                government funded shall be made within one hundred eighty (180)
                days after the end of the month for which the Capitation
                Payment applies.


                                          18

5.2     ADJUSTMENT FOR CLAIMS PROCESSING. If PacifiCare does not delegate
        performance of claims processing to Medical Group or if the delegation
        of claims processing is revoked by PacifiCare, PacifiCare shall deduct
        from monthly Capitation Payments an amount reasonably estimated by
        PacifiCare to be necessary for PacifiCare to process and pay claims for
        Medical Group Services which are not provided directly by Medical Group
        and its employed Participating Providers. Initially, this amount shall
        be [  **  ] of Medical Group's monthly Capitation Payment. This amount
        shall be increased or decreased each month to more accurately reflect
        Medical Group's actual and expected claims experience and any changes 
        in Covered Services which are provided or arranged by Medical Group and
        its Participating Providers, with adjustments for claims incurred but 
        not received.

5.3     ADJUSTMENT FOR REVOCATION OF DELEGATED ACTIVITIES. PacifiCare shall
        deduct the amounts specified in Article 4, above, for any Delegated
        Activity which is revoked by PacifiCare in accordance with the
        provisions of Article 4.

5.4     INCENTIVE PROGRAMS. Incentive programs are designed to ensure that
        PacifiCare, Medical Group and, for some programs, Hospital work
        collaboratively to deliver Covered Services in an effective and
        efficient manner by ensuring appropriate utilization of Covered
        Services. Incentive programs for each Managed Care Plan are set forth
        in the applicable Product Attachment.

        5.4.1   INCENTIVE PROGRAM WITHHOLD. PacifiCare shall establish a single
                withhold from Medical Group's monthly Capitation Payment for
                purposes of offsetting potential deficits for the combined
                incentive programs, excluding the Commercial Hospital Incentive
                Program and the Secure Horizons Hospital Incentive Program for
                which separate withholds may be established. The monthly
                incentive withhold shall initially be [  **  ] of Premium for
                each Managed Care Plan. PacifiCare, in its sole discretion, 
                shall prospectively adjust the withhold based on Medical Group's
                experience under the combined incentive programs at the time of 
                the program settlements described below.

        5.4.2   INCENTIVE PROGRAM SETTLEMENTS. PacifiCare shall conduct
                combined settlements for all of the incentive programs for
                Managed Care Plans applicable to Medical Group. Surpluses and
                deficits under each of the incentive programs shall be
                aggregated and offset against one another. PacifiCare will
                conduct an estimated calculation after six (6) months (the
                "Interim Calculation") and a final calculation annually (the
                "Final Calculation") based on the calendar year. The incentive
                program withhold described above shall be refunded to the
                Medical Group at the time of the incentive program settlements,
                except that Medical Group's share of any incentive program
                deficits shall be deducted from such refund. Payments under the
                combined incentive programs will be due from the owing party
                within one hundred and twenty (120) days following the end of
                the six (6) months for the Interim Calculation and within one
                hundred and eighty (180) days following the end of the calendar
                year for the Final Calculation. For the Interim Calculation,
                the payment due will be limited to [  **  ] of the calculated 
                amount due to account for incurred but not received claims. To
                the extent a Medical Group deficit has been carried forward from
                a prior settlement period, this deficit shall be offset against
                amounts due to Medical Group hereunder.

        5.4.3   INCENTIVE PROGRAM COMPLIANCE WITH STATE AND FEDERAL LAW.
                PacifiCare and Medical Group acknowledge and agree that the
                payments which may be made directly or indirectly under the
                incentive programs described in this Agreement are not made as
                an inducement to reduce or limit Covered Services to any
                specific Member. Medical Group acknowledges and agrees that any
                payments which may be made directly or indirectly under
                physician incentive programs Medical Group may utilize with
                respect to its Participating Providers shall not be made as an
                inducement to reduce or limit Covered Services to any specific
                Member. Medical Group further acknowledges and agrees that the
                incentive programs described in this Agreement shall be subject
                to modification by PacifiCare during the term of this Agreement
                in order to comply with changes in State and Federal Law, and
                Medical Group further agrees to modify any physician incentive
                programs utilized with respect to its Participating Providers
                to comply with such changes.

        5.4.4   LIMITATION ON MEDICAL GROUP'S RISK. In the event Medical Group
                incurs an obligation under the overall incentive program
                settlement described above, Medical Group shall not be
                responsible for reimbursing PacifiCare nor shall PacifiCare
                offset the Medical Group's obligation against Medical Group's
                Capitation Payments due under this Agreement. PacifiCare shall
                carry forward any Medical Group obligations as the result  of an
                incentive program obligation and the amount carried forward
                shall be offset against amounts otherwise due to Medical Group
                under future settlements for the combined incentive programs.

5.5     INDIVIDUAL STOP-LOSS PROGRAM. PacifiCare shall provide Individual
        Stop-Loss ("ISL") protection in order to limit Medical Group's
        financial risk for Medical Group Services. The ISL Program is designed
        to limit Medical Group's financial responsibility for Medical Group  
        Services to a specified dollar amount per Medical Group Member per 
        calendar year (the "ISL Deductible"), while encouraging Medical Group's
        continuing involvement with Medical Group Member's care by sharing a
        portion of the financial responsibility for Medical Group Services which
        exceed the ISL Deductible ("ISL Coinsurance"). PacifiCare shall charge a
        premium (the "ISL Premium") as consideration for the ISL Program. The
        ISL Deductible, ISL Coinsurance and ISL Premium for Medical Group are
        specified in each Product Attachment. Notwithstanding any other
        provision of this Agreement, PacifiCare may amend the ISL Deductible,
        ISL Coinsurance and ISL Premium on an annual basis effective at the
        beginning of any calendar year by providing sixty (60) calendar days
        prior written notice to Medical Group. For Medical Group Services which
        exceed the ISL Deductible, PacifiCare will pay Cost of Care, less the
        Medical Group's ISL Coinsurance amount, subject to the Medical Group's
        compliance with the procedures set forth in the Provider Manual and the
        provisions set forth below.

        5.5.1   SUBMISSION OF ISL CLAIMS. Medical Group shall submit all claims
                under the ISL Program in accordance with the procedures set
                forth in the Provider Manual. PacifiCare shall pay claims under
                the ISL Program only if such claims are submitted within one
                (1) year following the date the claim is incurred.


                                          20
<PAGE>

        5.5.2   NOTIFICATION OF ISL CLAIMS. Medical Group shall provide written
                notification to PacifiCare when Medical Group Services for any
                Medical Group Member(s) equal fifty percent (50%) of the ISL
                Deductible. Such written notification shall be provided to
                PacifiCare no later than the fifteenth (15th) day of the month
                following the month in which such threshold is reached. Medical
                Group acknowledges and agrees that if Medical Group fails to
                provide the written notice required by this Section within the 
                time frame specified in this Section, Medical Group shall be
                financially responsible for [  **  ] of all Medical Group 
                Services provided to the Medical Group Member(s) in excess of
                the ISL Deductible, which amount shall be in addition to the
                ISL Coinsurance.

        5.5.3   OPT-OUT FROM ISL PROGRAM. Subject to PacifiCare's approval,
                Medical Group may elect to opt out of the ISL Program,
                effective upon the Commencement Date or at the beginning of any
                calendar year. In such event, Medical Group shall be required
                to obtain stop-loss coverage from a third-party insurance
                carrier acceptable to PacifiCare and in the amounts required by
                PacifiCare and State and Federal Law. In order to opt-out of
                PacifiCare's ISL Program, Medical Group must provide written
                notice to PacifiCare at least thirty (30) days prior to the
                beginning of the calendar year. Such notice shall specify the
                name of the third-party insurance carder, and proposed
                effective date, coverage levels and charges. If PacifiCare does
                not object to such coverage in writing within fifteen (15) days
                of the date of the notice, Medical Group shall be required to
                purchase such coverage as of the effective date specified in
                the notice.

5.6     PAYMENTS FOLLOWING TERMINATION OF AGREEMENT. Following termination of
        this Agreement, PacifiCare shall make Capitation Payments to Medical
        Group as compensation for providing and arranging Covered Services to
        remaining Medical Group Members until transferred to PacifiCare
        Participating Providers.

5.7     COST OF CARE. Certain provisions of this Agreement require that Medical
        Group provide or arrange health care services which are not covered by
        Capitation Payments at Cost of Care and certain provisions of this
        Agreement require that Covered Services be valued at Cost of Care. For
        purposes of this Agreement, "Cost of Care" shall mean the amount
        determined to be payable for such health care services or Covered
        Services by PacifiCare as follows: (i) for professional services which
        are paid under the Medicare Fee Schedule, the Cost of Care shall be the
        lesser of billed charges or amount payable under the Medicare Fee
        Schedule; (ii) for all other health care services (other than inpatient
        and outpatient Hospital Services) which are paid by Medicare, the Cost
        of Care shall be the lesser of billed charges or amount payable by
        Medicare; (iii) for any other Covered Services or health care services
        covered under a Managed Care Plan which do not fall within any of the
        above specified categories, other than inpatient and outpatient Hospital
        Services, the Cost of Care shall be the lesser of billed charges or the
        amount determined under PacifiCare's allowable fee schedule.

5.8     COLLECTION OF COPAYMENTS. Medical Group and its Participating Providers
        shall be responsible for the collection of Copayments upon rendering
        Medical Group Services to Medical Group Members in accordance with the
        applicable Subscriber Agreement. Any Copayments which


                                          21
<PAGE>

        are stated as a percentage shall be calculated using the Cost of Care
        for such Medical Group Services.

5.9     COLLECTION OF CHARGES FROM THIRD PARTIES. If a Medical Group Member is
        entitled to payment from a third party (excluding a workers'
        compensation carrier or primary insurance carrier under applicable
        coordination of benefits rules), PacifiCare hereby assigns to Medical
        Group for collection, any claims or demands against such third parties
        for amounts due for Medical Group Services, subject to the following
        conditions: (i) To the extent liens are utilized, Medical Group shall
        utilize lien forms which are provided by PacifiCare or approved in
        advance by PacifiCare; (ii) Medical Group shall notify PacifiCare each
        time it pursues and each time it obtains a signed lien from a Medical
        Group Member; (iii) Medical Group shall not commence any legal action
        as it relates to this Agreement against a third party without obtaining
        the prior written consent of PacifiCare; (iv) Medical Group shall make
        no demand upon PacifiCare for reimbursement under the ISL Program until
        all third party claims have been pursued and it is determined that full
        payment cannot be obtained within twelve (12) months from the date of
        the provision of Medical Group Services; (v) PacifiCare may immediately
        rescind the assignment of any or all claims and demands against third
        parties by providing written notice of rescission to Medical Group; and
        (vi) in the event Medical Group receives payment from a third party
        after receipt of an ISL payment from PacifiCare, Medical Group shall
        reimburse PacifiCare to the extent that the combined amounts received
        from all parties exceeds [  **  ] of Medical Group's usual and customary
        fee-for-service rates.

5.10    COORDINATION OF BENEFITS. Medical Group shall cooperate with and
        support, as mutually agreed upon by the parties, PacifiCare's
        coordination of benefits rights.

        5.10.1   PLAN IS PRIMARY. If a Medical Group Member possesses health
                 benefits coverage through another policy which is secondary to
                 PacifiCare under applicable coordination of benefits rules,
                 including the Medicare secondary payor program, Medical Group
                 shall accept payment from PacifiCare for Covered Services as
                 provided herein as full payment for such Covered Services,
                 except for applicable Copayments. Medical Group Member shall
                 have no obligation for any fees, regardless of whether
                 secondary insurance is available.

        5.10.2   PLAN IS SECONDARY. If a Medical Group Member possesses health
                 benefits coverage through another policy which is primary to
                 PacifiCare under applicable coordination of benefits rules,
                 including the Medicare secondary payor program, or if Medical
                 Group Member is entitled to payment under a workers'
                 compensation policy or automobile insurance policy, Medical
                 Group may pursue payment from the primary payor or workers'
                 compensation carrier consistent with applicable law and
                 regulations and Medical Group's contract, if any, with the
                 primary payor. In such event, PacifiCare's responsibility
                 shall equal the amount of out-of-pocket expenses (i.e.,
                 Copayments, coinsurance, and deductibles) that Medical Group
                 Member would incur in) the absence of PacifiCare's secondary
                 coverage, minus the ISL Deductible and ISL Coinsurance.

5.11    OFFSETTING. Except as may otherwise be specifically provided in this
        Agreement, PacifiCare shall have the right to offset any and all
        amounts owed by Medical Group to PacifiCare against


                                          22

<PAGE>

        amounts, including Capitation Payments, owed by PacifiCare to Medical
        Group. This right to offset shall include, without limitation,
        PacifiCare's right to offset the following amounts owed to PacifiCare
        by Medical Group: (i) amounts owed by Medical Group due to overpayments
        or payments made in error by PacifiCare; (ii) amounts owed by Medical
        Group as a result of claims for Medical Group Services that PacifiCare
        may pay on behalf of Medical Group; (iii) amounts owed by Medical Group
        for Covered Services provided outside the Medical Group Service Area;
        and (iv) amounts owed by Medical Group as a result of the outcome of
        the Member appeals and grievance procedure.

5.12    ADEQUACY OF COMPENSATION. Medical Group agrees to accept payment as
        provided herein as payment in full for providing and arranging the
        Covered Services required under this Agreement, whether that amount is
        paid in whole or in part by Member, PacifiCare or any Subscriber,
        including other health care plans that pay before PacifiCare as
        required by applicable state or federal coordination of benefits
        provisions. This Section does not prohibit Medical Group from
        collecting applicable Copayments, coinsurance, or deductibles
        consistent with the Managed Care Plans.

<PAGE>

                 (i)     FINANCIAL FAILURE OF MEDICAL GROUP. PacifiCare's
                         reasonable determination of Medical Group's anticipated
                         inability to provide or arrange for Covered Services as
                         a result of the likelihood of Medical Group's lack of
                         financial resources, other than due to PacifiCare's
                         non-payment of amounts due Medical Group hereunder.
                         Medical Group shall have the opportunity to dispute
                         such determination by PacifiCare by providing
                         reasonable evidence and assurances of financial
                         stability and capacity to perform under this Agreement.

                 (ii)    FAILURE TO PROVIDE QUALITY SERVICES. Medical Group's
                         failure to arrange or provide Covered Services in
                         accordance with the standards set forth in this
                         Agreement and PacifiCare's QI Program and UM Program.
                         Notwithstanding the foregoing, PacifiCare reserves the
                         right to immediately withdraw from Medical Group or any
                         of its Participating Providers any or all Members in
                         the event the health or safety of Members is endangered
                         by the actions of Medical Group or any of its
                         Participating Providers or as a result of continuation
                         of this Agreement.

                 (iii)   BREACH OF MATERIAL TERM AND FAILURE TO CURE. Medical
                         Group's breach of any material term, covenant or
                         condition of this Agreement and subsequent failure to
                         cure such breach as provided below.

        6.2.3    NOTICE OF TERMINATION AND EFFECTIVE DATE OF TERMINATION. The
                 party asserting cause for termination of this Agreement (the
                 "terminating party") shall provide written notice of
                 termination to the other party. The notice of termination
                 shall specify the breach or deficiency underlying the cause
                 for termination. The party receiving the written notice of
                 termination shall have thirty (30) calendar days from the
                 receipt of such notice to cure the breach or deficiency to the
                 satisfaction of the terminating party (the "Cure Period"). If
                 such party fails to cure the breach or deficiency to the
                 satisfaction of the terminating party within the Cure Period
                 or if the breach or deficiency is not curable, the terminating
                 party shall provide written notice of failure to cure the
                 breach or deficiency to the other party following expiration
                 of the Cure Period. This Agreement shall terminate upon
                 receipt of the written notice of failure to cure or at such
                 other date as may be specified in such notice. During the Cure
                 Period, PacifiCare may cease marketing efforts for Medical
                 Group, discontinue enrollment of Members with Medical Group
                 and begin transferring Medical Group Members to other
                 PacifiCare Participating Providers.

6.3     AUTOMATIC TERMINATION UPON REVOCATION OF LICENSE OR CERTIFICATE. This
        Agreement shall automatically terminate upon the revocation, suspension
        or restriction of any license, certificate or other authority required
        to be maintained by Medical Group or PacifiCare in order to perform the
        services required under this Agreement or upon the Medical Group's or
        PacifiCare's failure to obtain such license, certificate or authority.

6.4     TERMINATION FOR TRANSFER TO A SUCCESSOR ENTITY. As set forth in Section
        7.12, PacifiCare shall have the right to terminate Medical Group on
        ninety (90) days prior written notice to Medical Group if PacifiCare
        reasonably determines that any successor entity or management company,  
        as defined in Section 7.12, cannot satisfactorily perform the
        obligations of Medical Group


                                          24
<PAGE>

        under this Agreement or that PacifiCare prefers not to do business with
        the successor entity or management company.

6.5     TRANSFER OF MEDICAL RECORDS. Following termination of this Agreement,
        at PacifiCare's request, Medical Group and its Participating Providers
        shall copy all requested Medical Group Member patient medical files in
        the possession of Medical Group or its Participating Providers and
        forward such files to another provider of Covered Services designated
        by PacifiCare, provided such copying and forwarding is not otherwise
        objected to by such Members. The copies of such medical files may be in
        summary form. The cost of copying the patient medical files shall be
        borne by Medical Group. Medical Group shall cooperate with PacifiCare
        in maintaining the confidentiality of such Member medical records at
        all times.

6.6     REPAYMENT UPON TERMINATION. Within one hundred eighty (180) calendar
        days of the effective date of termination of this Agreement, an
        accounting shall be made by PacifiCare of the monies due and owing
        either party and payment shall be forthcoming by the appropriate party
        to settle such balance within thirty (30) calendar days of such
        accounting. Either party may request an independent audit of such
        PacifiCare accounting by a mutually acceptable independent certified   
        public accountant and such audit shall be equally paid for by both
        parties. The parties agree to abide by the findings of such
        independent audit. Appropriate payment, if any, by the appropriate
        party shall be made within thirty (30) calendar days of such
        independent audit.

6.7     TERMINATION NOT AN EXCLUSIVE REMEDY. Any termination by either party
        pursuant to this Article is not meant as an exclusive remedy and such
        terminating party may seek whatever action in law or equity as may be
        necessary to enforce its rights under this Agreement.

                                      ARTICLE 7
                                  GENERAL PROVISIONS

7.1     INDEPENDENT CONTRACTOR RELATIONSHIP. The relationship between
        PacifiCare and Medical Group is an independent contractor relationship.
        Neither Medical Group nor its Participating Providers, employees or
        agents are employees or agents of PacifiCare and neither PacifiCare nor
        its employees or agents are members, partners, employees or agents of
        Medical Group. None of the provisions of this Agreement shall be
        construed to create a relationship of agency, representation, joint
        venture, ownership, control of employment between the parties other
        than that of independent parties contracting solely for the purpose of
        effectuating this Agreement. Nothing contained in this Agreement shall
        cause either party to be liable or responsible for any debt, liability
        or obligation of the other party or any third party unless such
        liability or responsibility is expressly assumed by the party sought to
        be charged therewith.

7.2     RESPONSIBILITY FOR OWN ACTS. Each party shall be responsible for its
        own acts or omissions and for any and all claims, liabilities,
        injuries, suits, demands and expenses of all kinds which may result or
        arise out of any alleged malfeasance or neglect caused or alleged to
        have been caused by that party or its employees or representatives in
        the performance or omission of any act or responsibility of that party
        under this Agreement. In the event that a claim is made against both 
        parties, it is the intent of both parties to cooperate in the defense
        of said claim and to cause their insurers to do likewise. However both
        parties shall have the right to take any and all actions they believe
        necessary to protect their interest.

7.3     PHYSICIAN-PATIENT RELATIONSHIP. PacifiCare and Medical Group
        acknowledge and agree that Medical Group or each of Medical Group's
        Participating Providers shall maintain the physician-patient
        relationship with each Medical Group Member. Nothing contained in this  
        Agreement is intended to interfere with such physician-patient
        relationship. Nothing in this Agreement shall be interpreted to
        discourage or prohibit Medical Group and its Participating Providers
        from discussing treatment options or providing other medical advice or
        treatment deemed appropriate by Medical Group or its Participating
        Providers. Medical Group or its Participating Providers shall have the
        sole responsibility for the medical care and treatment of Medical
        Group Members.

7.4     MEMBER APPEALS AND GRIEVANCES. PacifiCare shall be responsible for
        resolving Medical Group Member claims for benefits under the Managed
        Care Plans and all other claims against PacifiCare. PacifiCare shall
        resolve such claims utilizing the Member Appeals and Grievance
        Procedures set forth in the Subscriber Agreement and the Provider
        Manual. Medical Group shall assist PacifiCare in the handling of Member
        complaints, grievances and appeals, consistent with the Member Appeals
        and Grievance Procedures. In the event an oral or written complaint,
        grievance or appeal is presented to Medical Group or any of its
        Participating Providers relating to benefits or coverage under a
        Managed Care Plan and is not resolved within two (2) business days,
        Medical Group or its Participating Provider will immediately deliver    
        such complaint, grievance or appeal to PacifiCare for handling pursuant
        to the Member Appeals and Grievance Procedures. At the end of each
        month, Medical Group shall submit a report to PacifiCare of all Medical
        Group Member complaints and grievances which were received and resolved
        by Medical Group and its Participating Providers within two (2) business
        days during the previous month. The monthly report shall include the
        Medical Group Member's name and PacifiCare identification number, date
        of complaint, nature of complaint, and the resolution of complaint.
        Medical Group and its Participating Providers shall comply with all
        final determinations made by PacifiCare through the Member Appeals and
        Grievance Procedures. Medical Group Member claims against Medical
        Group or its Participating Providers, other than claims for benefits
        under the Managed Care Plans, are not subject to the Member Appeals
        and Grievance Procedures and are not governed by this Agreement.

7.5     DISPUTES BETWEEN MEDICAL GROUP OR ITS PARTICIPATING PROVIDERS AND
        MEMBER. Any controversies or claims between Medical Group or its
        Participating Providers and a Member arising out of the performance of
        this Agreement by Medical Group or the Medical Group's Participating
        Provider, other than claims for benefits under Managed Care Plans, are
        not governed by this Agreement. Medical Group or its Participating
        Provider and the Member may seek any appropriate legal action to
        resolve such controversy or claim deemed necessary.

7.6     DISPUTES BETWEEN PACIFICARE AND MEDICAL GROUP


                                          26

<PAGE>

        7.6.1    DISPUTE RESOLUTION PROCEDURE. PacifiCare has established a
                 Provider Dispute Resolution Procedure, set forth in the
                 Provider Manual, to provide a mechanism by which PacifiCare's
                 Participating Providers, including Medical Group and any of
                 its Participating Providers, may submit to PacifiCare certain
                 disputes arising out of the performance of this Agreement or
                 relating to the decisions made by PacifiCare under this
                 Agreement for resolution on an informal basis. Any dispute
                 submitted pursuant to the Provider Dispute Resolution
                 Procedure should be addressed to the appropriate PacifiCare
                 person(s) or department(s) at the address and/or telephone
                 number identified in the Provider Manual. Any provider dispute
                 which is not resolved informally through the Provider Dispute
                 Resolution Procedure may be submitted for arbitration as
                 provided in Section 7.6.2 below.

        7.6.2    ARBITRATION. Any controversy, dispute or claim arising out of
                 the interpretation, performance or breach of this Agreement
                 which is nor resolved pursuant to the Provider Dispute
                 Resolution Procedure specified above shall be resolved by
                 binding arbitration at the request of either party, in
                 accordance with the Commercial Rules of the American
                 Arbitration Association. Such arbitration shall occur in Los
                 Angeles, California, unless the parties mutually agree to have
                 such proceeding in some other locale. The arbitrators shall
                 apply California substantive law and federal substantive  law
                 where state law is preempted. Civil discovery for use in such
                 arbitration may be conducted in accordance with the provisions
                 of California law, and the arbitrator(s) selected shall have
                 the power to enforce the rights, remedies, duties, liabilities
                 and obligations of discovery by the imposition of the same
                 terms, conditions and penalties as can be imposed in like
                 circumstances in a civil action by a court of competent
                 jurisdiction of the State of California. The provisions of
                 California law concerning the right to discovery and the use
                 of depositions in arbitration are incorporated herein by  
                 reference and made applicable to this Agreement.

                 The arbitrators shall have the power to grant all legal and
                 equitable remedies and award compensatory damages provided by
                 California law, except that punitive damages shall not be
                 awarded. The arbitrators shall prepare in writing and provide
                 to the parties an award including factual findings and the
                 legal reasons on which the award is based. The arbitrators
                 shall not have the power to commit errors of law or legal
                 reasoning.

                 Notwithstanding the above, in the event either Medical Group
                 or PacifiCare wishes to obtain injunctive relief or a
                 temporary restraining order, such party may initiate an action
                 for such relief in a court of general jurisdiction in the
                 State of California. The decision of the court with respect to
                 the requested injunctive relief or temporary restraining order
                 shall be subject to appeal only as allowed under California
                 law. However, the courts shall not have the authority to
                 review or grant any request or demand for damages.

7.7     NOTICE. All notices required or permitted by this Agreement shall be in
        writing and may be delivered in person or may be sent by registered or

<PAGE>

                 amendment shall be binding upon Medical Group at the end of

        7.10.2   NON-DISCLOSURE OF CONFIDENTIAL INFORMATION. Medical Group and
                 its Participating Providers shall not disclose or use the
                 Confidential Information for their own benefit or gain either
                 during the term of this Agreement or after the date of
                 termination of this Agreement. Medical Group and its
                 Participating Providers may use the Confidential Information
                 to the extent necessary to perform their duties under this
                 Agreement or upon express prior written permission of
                 PacifiCare. Upon the effective date of termination of this
                 Agreement, Medical Group and its Participating Providers shall


                                          29

<PAGE>

                 provide and return to PacifiCare the Confidential Information
                 in their possession in the manner specified by PacifiCare.

        7.10.3   INFORMATION CONFIDENTIAL AND PROPRIETARY TO MEDICAL GROUP.
                 Medical Group shall provide PacifiCare with a written
                 description of all information proprietary to Medical Group
                 which is confidential and contains trade secrets of Medical
                 Group (the "Medical Group Information"). PacifiCare shall
                 maintain and shall cooperate with Medical Group to maintain
                 the confidentiality of Medical Group Information. PacifiCare
                 shall not disclose or use any Medical Group Information for
                 its own benefit either during the term of this Agreement or
                 after the effective date of termination of this Agreement.
                 Upon termination of this Agreement, PacifiCare shall provide
                 and return to Medical Group all Medical Group Information in
                 its possession in the manner to be specified by Medical Group.

        7.10.4   PACIFICARE NAMES, LOGOS AND SERVICE MARKS. Medical Group shall
                 obtain the written consent of PacifiCare prior to using
                 PacifiCare's name, product names, logos and service marks in
                 any of Medical Group's promotional, marketing or advertising
                 materials or for any other reason.

7.11    SOLICITATION OF PACIFICARE MEMBERS OR SUBSCRIBER GROUPS. Medical Group
        and its Participating Providers shall not engage in the practice of
        solicitation of Members, Subscribers and Subscriber Groups without
        PacifiCare's prior written consent. Solicitation shall mean conduct by
        an officer, agent, employee of Medical Group or its Participating
        Providers or their respective assignees or successors during the term
        of this Agreement and continuing for a period of one (1) year after the
        effective date of termination of this Agreement which may be reasonably
        interpreted as designed to persuade Members, Subscribers or Subscriber
        Groups to disenroll from any Managed Care Plan or discontinue their
        relationship with PacifiCare. Notwithstanding any other provision of
        this Agreement, Medical Group agrees that PacifiCare shall, in addition
        to any other remedies provided for under this Agreement, have the right
        to seek a judicial temporary restraining order, preliminary injunction,
        or other equitable relief against Medical Group and its Participating
        Providers to enforce its rights under this Section. Nothing in this
        Agreement shall be interpreted to discourage or prohibit Medical Group
        and its Participating Providers from discussing a Member's health care,
        including, without limitation, communications regarding treatment
        options, alternative plans or other coverage arrangements, unless such
        communications are for the primary purpose of securing financial gain.

7.12    NOTIFICATION AND APPROVAL OF SALE OR CHANGE IN MANAGEMENT OF MEDICAL
        GROUP. Medical Group agrees that it shall provide prior written notice
        to PacifiCare of its intent to either (i) sell, transfer or convey its
        business or any substantial portion of its business assets to another
        entity ("successor entity") or (ii) enter into a management contract
        with a physician practice management company ("management company")
        which does not manage Medical Group as of the Commencement Date. Such
        prior written notice shall be given at least ninety (90) days prior to
        Medical Group selling its business or entering into such contract. As
        set forth in Section 6.4, PacifiCare shall have the fight to terminate
        this Agreement upon ninety (90) days written notice to Medical Group if
        PacifiCare reasonably determines that any successor entity or any
        management company cannot satisfactorily perform the obligations of
        Medical Group under this Agreement or that PacifiCare prefers not to do
        business with the successor entity or 


                                          30

<PAGE>

        management company. Medical Group warrants and assures that this
        Agreement, if not otherwise terminated by PacifiCare, will be assumed
        by all successor entities and that all successor entities and
        management companies will be bound by the terms and conditions of this
        Agreement.

7.13    CONFIDENTIALITY OF THIS AGREEMENT. To the extent reasonably possible,
        each party agrees to maintain this Agreement as a confidential document
        and not to disclose the Agreement or any of its terms without the
        approval of the other party.

7.14    INVALIDITY OF SECTIONS OF AGREEMENT. The unenforceability or invalidity
        of any paragraph or subparagraph of any section or subsection of this
        Agreement shall not affect the enforceability and validity of the
        balance of this Agreement.

7.15    CAPTIONS. Captions in this Agreement are descriptive only and do not
        affect the intent or interpretation of the Agreement.

7.16    WAIVER OF BREACH. The waiver by either party to this Agreement of a
        breach or violation of any provision of this Agreement shall not
        operate as or be construed to be a waiver of any subsequent breach or
        violation thereof.

7.17    MEDICAL GROUP'S AUTHORIZED REPRESENTATIVE. Unless otherwise indicated
        in writing to PacifiCare, Medical Group warrants and authorizes its
        administrator to act as its fully authorized representative to
        represent Medical Group in this Agreement and to receive any and
        all communications and notices hereunder.

7.18    NO THIRD PARTY BENEFICIARIES. This Agreement shall not create any
        rights in any third parties who have not entered into this Agreement,
        nor shall this Agreement entitle any such third party to enforce any
        rights or obligations that may be possessed by such third party.

7.19    ENTIRE AGREEMENT. This Agreement, including all exhibits, attachments
        and amendments hereto, contains all the terms and conditions agreed
        upon by the parties regarding the subject matter of this Agreement. Any
        prior agreements, promises, negotiations or representations of or
        between the parties, either oral or written, relating to the subject
        matter of this Agreement, which are not expressly set forth in this
        Agreement are null and void and of no further force or effect.

7.20    INCORPORATION OF EXHIBITS, ATTACHMENTS AND PROVIDER MANUAL. The exhibits
        and attachments to this Agreement and the Provider Manual are an
        integral part of this Agreement and are incorporated in full herein by
        this reference.

                                      ARTICLE 8
                      GOVERNING LAW AND REGULATORY REQUIREMENTS

8.1     GOVERNING LAW. This Agreement and the rights and obligations of the
        parties hereunder shall be construed, interpreted, and enforced in
        accordance with, and governed by, the laws of the State of California
        and the United States of America, including, without limitation, the
        Knox-Keene Health Care Service Plan Act of 1975, as amended, and the
        regulations adopted


                                          31

<PAGE>

        thereunder by the California Department of Corporations, the federal
        Health Maintenance Organization Act of 1973, as amended, and the
        regulations adopted thereunder by the United States Department of
        Health and Human Services. Any provisions required to be in this
        Agreement by State and Federal Law or by Government Agencies shall bind
        PacifiCare and Medical Group whether or not expressly provided in this
        Agreement.

8.2     NO BILLING OF MEMBERS (MEMBER HOLD HARMLESS PROVISION). With the
        exception of Copayments and charges for non-covered services delivered
        on a fee-for-service basis to Members, Medical Group shall in no event,
        including, without limitation, non-payment by PacifiCare, insolvency of
        PacifiCare, or breach of the Agreement, bill, charge, collect a deposit
        from, or attempt to bill, charge, collect or receive any form of
        payment from any Member for Covered Services provided or arranged
        pursuant to this Agreement.

        Medical Group and its Participating Providers shall not maintain any
        action at law or equity against a Member to collect sums owed by
        PacifiCare to Medical Group. Upon notice of any such action, PacifiCare
        may terminate this Agreement as provided above and take all other
        appropriate action consistent with the terms of this Agreement to
        eliminate such charges, including, without limitation, requiring
        Medical Group and its Participating Providers to return all sums
        collected as surcharges from Members or their representatives. For
        purposes of this Agreement, "Surcharges" are additional fees for
        Covered Services which are not disclosed to Members in the Subscriber
        Agreement, are not allowable Copayments and are not authorized by this
        Agreement. Nothing in this Agreement shall be construed to prevent
        Medical Group from providing non-Covered Services on a usual and
        customary fee-for-service basis to Members.

        Medical Group's obligations under this Section shall survive the
        termination of this Agreement with respect to Covered Services provided
        or arranged during or after the term of this Agreement, regardless of
        the cause giving rise to such termination.

8.3     CONTINUING CARE OBLIGATIONS OF MEDICAL GROUP. In the event of
        termination of this Agreement for any reason, Medical Group and its
        Participating Providers shall continue to provide or arrange Covered
        Services to Members, including any Members who become eligible during
        the termination notice period, beginning on the effective date of
        termination and continuing until the termination or next renewal date
        of the Member's Subscriber Agreement, unless PacifiCare arranges for
        the transfer of the Member to another PacifiCare Participating Provider
        and provides written notice to Medical Group of such transfer prior to
        the termination or next renewal date of the Subscriber Agreement.
        Notwithstanding the foregoing, Medical Group and its Participating
        Providers will continue to provide or arrange Covered Services to any   
        Members who cannot be transferred within the time period specified
        above in accordance with PacifiCare's legal and contractual
        obligations to (i) provide Covered Services under the Managed Care
        Plans and Subscriber Agreements, (ii) provide notice of termination
        to Members and (iii) ensure continuity of care for its Members.

        Notwithstanding the above or any other provisions to the contrary,
        Medical Group agrees that in the event PacifiCare ceases operations for
        any reason, including insolvency, Medical Group shall provide or
        arrange Covered Services and shall not bill, charge, collect or receive
        any form of payment from any Member for Covered Services provided after
        PacifiCare ceases


                                          32

<PAGE>

        operations. This continuation of Covered Services obligation shall be
        for the period for which Premium has been paid, but shall not exceed a
        period of thirty (30) calendar days, except for those Members who are
        hospitalized on an inpatient basis as provided below.

        In the event PacifiCare ceases operations or Medical Group terminates
        this Agreement on the basis of PacifiCare's failure to make timely
        Capitation Payments, Medical Group shall continue to arrange for
        Covered Services to those Members who are hospitalized on an inpatient
        basis at the time PacifiCare ceases operations or Medical Group
        terminates this Agreement until such Members are discharged from the
        hospital. Medical Group may file a claim with PacifiCare for such
        services as previously specified in this Section.

        Medical Group agrees that the provisions of this Section and the
        obligations of Medical Group and its Participating Providers herein
        shall survive termination of this Agreement regardless of the cause
        giving rise to such termination, and shall be construed to be for the
        benefit of Members.

8.4     INSPECTION AND AUDIT OF RECORDS AND FACILITIES. Upon written notice,
        Medical Group and its Participating Providers shall allow access during
        normal business hours to PacifiCare, Accreditation Organizations and
        Governmental Agencies to periodically audit or inspect the facilities,
        offices, equipment, books, documents and records of Medical Group and
        its Participating Providers relating to the performance of this
        Agreement and the Covered Services provided to Members, including,
        without limitation, all phases of professional and ancillary medical
        care provided or arranged for Members by Medical Group and its
        Participating Providers, Member medical records and financial records
        pertaining to the cost of operations and income received by Medical
        Group for Covered Services rendered to Members. Medical Group and its
        Participating Providers shall comply with any requirements or
        directives issued by PacifiCare, Accreditation Organizations and
        Government Agencies as a result of such evaluation, inspection or audit
        of Medical Group and its Participating Providers. Medical Group and its
        Participating Providers shall retain the books and records described in
        this Section for at least five (5) years. The provisions of this
        Section shall survive termination of this Agreement for the period of
        time required by State and Federal Law.

8.5     NONDISCRIMINATION. Medical Group assures that Covered Services shall be
        provided to Members in the same manner as such services are provided to
        other patients of Medical Group and its Participating Providers, except
        as required pursuant to this Agreement. Medical Group and its
        Participating Providers shall not unlawfully discriminate against any
        Member on the basis of source of payment or in any manner in regards to
        access to, and the provision of, Covered Services. Medical Group and
        its Participating Providers shall not unlawfully discriminate against
        any Member, employee or applicant for employment on the basis of race,  
        religion, color, national origin, ancestry, physical handicap, medical
        condition, marital status, age or sex.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement in Los
Angeles, California.

SUMMARY OF CREDENTIALING, RECREDENTIALING AND PEER REVIEW STANDARDS AND
REQUIREMENTS

The PacifiCare credentialing and recredentialing process is designed to provide
ongoing verification of the credentials of Participating Providers and their
ability to render specific patient care and treatment to Members within limits
defined by licensure, education, experience, health status and judgment, thereby
ensuring the competency of the physicians and other health care practitioners
providing services within PacifiCare's health delivery system. The following
outline is a summary of PacifiCare's credentialing, recredentialing and peer
review standards and requirements. Detailed standards and requirements are set
forth in the Provider Manual.

I.   PACIFICARE CREDENTIALING PROGRAM

     A.   PACIFICARE CREDENTIALING APPLICATION

          All individual Participating Providers ("Practitioners") must complete
          and submit PacifiCare's approved credentialing application to be
          considered for participation in PacifiCare's health delivery system.
          The credentialing application includes a release and authorization to
          review confidential credentialing information and an attestation      
          regarding the correctness and completeness of the information
          submitted.

     B.   PACIFICARE CREDENTIALING STANDARDS

          PacifiCare has established credentialing standards sufficient to meet
          or exceed credentialing standards of Accreditation Organizations, and
          all Participating Providers must be credentialed according to these
          standards. PacifiCare's credentialing standards generally require the
          following of Practitioners, as defined by Accreditation Organizations:

          1.   Obtaining and verifying for each Practitioner the following
               information from primary sources:

               (a)  a current valid license to practice medicine or osteopathy;


                                          36

<PAGE>

               (b)  clinical privileges in good standing at the hospital 
                    designated by the practitioner as the primary admitting 
                    facility;
               (c)  a valid DEA or CDS certificate, as applicable;
               (d)  graduation from medical school and completion of a 
                    residency, or board certification, as applicable;
               (e)  work history;
               (f)  current adequate malpractice insurance as described in 
                    this Agreement and the Provider Manual; and
               (g)  professional liability claims history.

          2.   Obtaining from each Practitioner a statement or attestation 
               regarding physical and mental health status and lack of 
               present illegal drug use, history of loss or limitation of 
               medical license and/or felony convictions and history or loss 
               or limitation of hospital clinical privileges or disciplinary 
               activity;

          3.   Requesting information concerning each Practitioner from the 
               National Practitioner Data Bank and the California Medical 
               Board and reviewing for previous sanction activity by Medicare 
               and Medicaid.

          4.   Reporting Practitioners to the California Medical Board as 
               required by State law and to the National Practitioner Data 
               Bank as required by the federal Health Care Quality 
               Improvement Act.

     C.   APPROVAL AND TERMINATION OF PARTICIPATING PROVIDERS.

          Medical Group acknowledges and agrees: (i) that only Participating 
          Providers who meet PacifiCare's credentialing standards shall be 
          approved by PacifiCare to provide Covered Services to Members; and 
          (ii) that PacifiCare retains the right, in its sole discretion, to 
          approve or disapprove any Participating Provider to provide Covered 
          Services to Members and to suspend or terminate any Participating 
          Provider from continuing to provide Covered Services to Members at 
          any time. Participating Providers who are disapproved by PacifiCare 
          shall not provide Covered Services to PacifiCare Members.

          1.   NOTICE OF INITIAL CREDENTIALING

               Medical Group shall provide PacifiCare with written notice of 
               each new Participating Provider credentialed by Medical Group 
               at least thirty (30) days prior to the Participating Provider 
               providing Covered Services to Members. New Participating 
               Providers shall be deemed approved by PacifiCare at the end of 
               such thirty (30) day period unless Medical Group is notified 
               otherwise in writing.

                                      ARTICLE 3
                                     COMPENSATION

3.1  CAPITATION PAYMENTS FOR COMMERCIAL PLAN MEMBERS. Capitation Payments for
     Commercial Plan Members shall be [  **  ] of the Commercial Plan Premium
     per Commercial Plan Member per month, subject to the adjustments set forth
     in Article 5 of the Base Agreement and the adjustments set forth below in
     this Section.

     3.1.1  PREMIUM ADJUSTMENTS. The Commercial Plan Premium and benefits may
            be amended for each Subscriber Agreement upon the annual renewal
            date of each Subscriber Agreement at the sole discretion of
            PacifiCare.

     3.1.2  ADJUSTMENT FOR ISL PREMIUM. In calculating Capitation Payments due

            Payments for Experience Rated Plans shall be calculated utilizing
            the following definitions and methodology:

            (i)     An "Experience-Rated Plan" is a non-federally-qualified plan
                    in which the Subscriber Group's premium is partially
                    deferred or adjusted to reflect the actual medical costs
                    incurred by Commercial Plan Members.

            (ii)    The "Net Actuarial Experience Rate" shall mean a rate
                    calculated by the same method used to determine premium for
                    federally-qualified plans, except that trended claims and
                    utilization data may be considered to determine expected
                    medical costs and PacifiCare's administrative retention may
                    be adjusted to reflect actuarial risk taken by the
                    Subscriber Group instead of PacifiCare.

            (iii)   For Experience-Rated Plans, Capitation Payments shall be
                    calculated as a percent of the Net Actuarial Experience Rate
                    rather than based on a percent of the Commercial Plan
                    Premium. The Net Actuarial Experience Rate, like the
                    Commercial Plan Premium, shall exclude broker and agent
                    commissions, premium taxes and premiums for Supplemental
                    Benefits.

            PacifiCare for Outpatient Pharmacy Supplemental Benefits for
            Commercial Plan Members. The PIP Budget shall be retained by
            PacifiCare for purposes of administering the PIP.

     3.4.3  PIP EXPENSE shall equal the actual or valued expenses incurred for
            the provision of Outpatient Pharmacy Supplemental Benefits during
            the applicable period, less amounts received from pharmacy rebates
            and third parties as the result of coordination of benefits and
            third party recoveries.

     3.4.4  PIP SURPLUS. In the event the PIP Expense is less than the PIP
            Budget, [  **  ] of the surplus shall be allocated to Medical Group.

     3.4.5  PIP DEFICIT. In the event that the PIP Expense is greater than the
            PIP Budget, [  **  ] of the deficit shall be allocated to Medical 
            Group.

                         DIVISION OF FINANCIAL RESPONSIBILITY
                    (PacifiCare Commercial & Secure Horizons Plan)

The following matrix outlines the division of financial responsibility between
PacifiCare, Medical Group and Hospital, the intent being to clarify Covered
Services categories in order to provide for accurate administration. The matrix
serves as a model under which broad Covered Service categories suggest the
appropriate financial responsibility for Covered Services not specifically
listed. The applicable Subscriber Agreement should be consulted for an accurate
and complete description of Covered Services and the Provider Manual for
administrative clarification.

                     during the period of calculation.

              (iii)  BUDGET SURPLUS. The amount, if any, by which the POS Plan
                     Budget exceeds the Out-of-Network Costs for any calendar
                     year.

               (iv)  BUDGET DEFICIT. The amount, if any, by which the

               (v)   CAPITATION RESTORATION AMOUNT. The difference between (a)
                     the actual capitation paid to Medical Group or Hospital
                     for Commercial POS Plan Members for the relevant contract
                     year and (b) the amount Medical Group or Hospital would
                     have received if Medical Group's Capitation Payments for

                     multiplying the percentage set forth in Section 3.1 of
                     Product Attachment A by the In-Network Premium. The

     3.2.2     DOCUMENTATION. PacifiCare shall provide Medical Group with a list

               accuracy of Out-of-Network Costs, third party liability and
               coordination of benefit recoveries, assumptions and data
               supporting the POS Plan Budget, the Budget Surplus, and the
               Budget Deficit and the Capitation Restoration Amount.

     3.2.3     BUDGET SURPLUS RECONCILIATION. Medical Group and Hospital shall
               each receive [  **  ] of the Budget Surplus, until such time as
               either Hospital or Medical Group has received the applicable 
               Capitation Restoration Amount. Additional Budget Surplus amounts
               shall be paid to the party whose capitation has yet to be 
               restored until that party has received the applicable Capitation
               Restoration Amount. If the Budget Surplus exceeds the Capitation
               Restoration Amount for both Hospital and Medical Group, then
               PacifiCare, Hospital and Medical Group shall each be entitled to
               [  **  ] of the remaining Budget Surplus.

     3.2.4     BUDGET DEFICIT RECONCILIATION. In the event of a Budget Deficit,
               neither Medical Group nor Hospital shall be responsible for
               making any payments under the PacifiCare POS Control Program.
               However, [  **  ] of the Budget Deficit amount shall be 
               considered a Medical Group obligation for purposes of offsetting
               surpluses under other incentive programs under the Agreement.

3.3  ADJUSTMENT OF RATES. Capitation Payments for Commercial POS Plan Members
     and the POS Plan Budget may be prospectively adjusted on an annual basis to
     reflect actual experience under the PacifiCare Commercial POS Plan;
     provided, however, that in no event shall the amount of any increase or
     decrease to such Capitation Payments be greater than [  **  ] in any given
     year.

      3.1.1    ADJUSTMENT FOR ISL PREMIUM. In calculating Capitation Payments
               due to Medical Group, PacifiCare shall deduct the ISL Premium
               amount set forth herein from the amounts otherwise due to Medical
               Group, unless PacifiCare has approved of Medical Group's opting

3.3   MARKET-SPECIFIC BENEFIT PROGRAM. PacifiCare may establish, at its sole

          Respite Care

      PacifiCare shall retain [  **  ] of the Monthly HCFA Payment (the "MSBP
      Budget") for purposes of funding and administering the MSBP. The MSBP 
      shall be calculated as follows:

      3.4.1    MSBP BENEFITS shall be the additional benefits listed above in
               this Section and made available under the Secure Horizons Health
               Plan as defined in the applicable Subscriber Agreement.

      3.4.2    MSBP EXPENSE shall equal the actual or valued expenses incurred
               for the provision of MSBP Benefits during the applicable period,
               less amounts received from pharmacy rebates (in the case of
               Outpatient Pharmacy Benefits) and third parties as the result of
               coordination of benefits and third party recoveries.

      3.4.3    MSBP SURPLUS. In the event the MSBP Expense is less than the MSBP
               Budget, [  **  ] of the surplus shall be allocated to the Medical
               Group, but not more than [  **  ] of the MSBP Budget for the 
               calendar year.

      3.4.4    MSBP DEFICIT. In the event the MSBP Expense is greater than the
               MSBP Budget, [  **  ] of the deficit shall be allocated to the

               the calendar year.

      3.4.5    SETTLEMENTS. The calculations in this Section and settlements
               shall be performed in accordance with the procedures specified in
               Article 5 of the Base Agreement.

3.5   COLLECTION OF CHARGES FROM THIRD PARTIES WHEN MEDICARE IS NOT THE
      PRIMARY, PAYOR. Medical Group shall accept Capitation Payments from
      PacifiCare as payment in full for Covered Services provided to Secure
      Horizons Members; provided, however, when Medicare is not the primary     
      payor for Covered Services, such as when the Secure Horizons Member is
      entitled to payment from another third party or for payment for a workers'
      compensation claim, or from other primary insurance coverage maintained
      by Secure Horizons Member, Medical Group shall make no demand upon
      PacifiCare for reimbursement under the Individual Stop Loss Program until
      all primary sources of payment have been pursued and it is determined that
      full payment cannot be obtained within ten (10) months from the date of
      the provision of Covered Services.

                                      ARTICLE 4
                         DIVISION OF FINANCIAL RESPONSIBILITY
                                  (Secure Horizons)

The following matrix outlines the division of financial responsibility between
PacifiCare, Medical Group and Hospital, the intent being to clarify Covered
Services categories in order to provide for accurate administration. The matrix
serves as a model under which broad Covered Service categories suggest the
appropriate financial responsibility for Covered Services not specifically
listed. The

Health Plan.

      such Capitation Payments be greater than [  **  ] points in any given 
      year.
