Dear Stockholder:
 
     You are cordially invited to attend a Special Meeting of Stockholders of
Health Partners, Inc. ("HPI"), which will be held at 10:00 a.m., local time, on
            , 1997 at HPI's corporate headquarters, 800 Connecticut Avenue,
Norwalk, Connecticut, and any adjournments or postponements thereof (the "HPI
Special Meeting").
 
     At the HPI Special Meeting, holders of HPI's common stock and preferred
stock will be asked to consider and vote upon a proposal to approve and adopt
the Agreement and Plan of Merger dated as of July 1, 1997 (the "Merger
Agreement") by and among FPA Medical Management, Inc. ("FPA"), FPA Acquisition
Corp., a wholly owned subsidiary of FPA ("Merger Sub"), and HPI. A copy of the
Merger Agreement is included as Appendix A to the attached Proxy
Statement/Prospectus. On the terms and subject to the conditions of the Merger
Agreement, Merger Sub will be merged with and into HPI (the "Merger"), and HPI
will continue in existence as a wholly owned subsidiary of FPA.
 
     THE BOARD OF DIRECTORS OF HPI, AFTER CAREFUL CONSIDERATION, HAS UNANIMOUSLY
APPROVED THE MERGER AGREEMENT AND DETERMINED THAT THE MERGER IS FAIR TO, AND IN
THE BEST INTERESTS OF, HPI AND ITS STOCKHOLDERS AND RECOMMENDS THAT YOU VOTE FOR
APPROVAL OF THE MERGER AGREEMENT.
 
     At the HPI Special Meeting, you will also be asked to consider and vote
upon a proposal to approve certain payments and benefits (the "Payments") to be

will be converted into the right to receive a number of shares of FPA common
stock equal to the Exchange Ratio, which is based on a formula set forth in the
Merger Agreement and described in the attached Proxy Statement/Prospectus. Based
on such formula, management of HPI believes that the Exchange Ratio will fall
between .43 and .55 shares of FPA common stock for each share of HPI common
stock.

    This Proxy Statement/Prospectus ("Proxy Statement/Prospectus") is being
furnished to the stockholders of Health Partners, Inc., a Delaware Corporation
("HPI"), in connection with the solicitation of proxies by the Board of
Directors of HPI (the "HPI Board") for use at a Special Meeting of stockholders
to be held at HPI's corporate headquarters, 800 Connecticut Avenue, Norwalk,
Connecticut on            , 1997, at 10:00 a.m. local time (the "HPI Special
Meeting") to (i) approve the Agreement and Plan of Merger dated as of July 1,
1997 (the "Merger Agreement") by and among HPI, FPA Medical Management, Inc., a
Delaware corporation ("FPA"), and FPA Acquisition Corp., a Delaware corporation
and wholly owned subsidiary of FPA ("Merger Sub"), relating to the merger
("Merger") of Merger Sub with and into HPI and (ii) approve certain payments and
benefits (the "Payments") to Charles G. Berg, President and Chief Executive
Officer of HPI. APPROVAL OF THE PAYMENTS IS NOT A CONDITION TO THE CONSUMMATION
OF THE MERGER. As a result of the Merger, HPI will become a wholly owned
subsidiary of FPA. In connection with the Merger, each outstanding share of HPI
Common Stock, par value $.001 per share ("HPI Common Stock"), will be exchanged
for the right to receive a number of shares of FPA Common Stock, par value $.002
per share ("FPA Common Stock"), equal to the "Exchange Ratio." The holders of
HPI Preferred Stock have agreed to convert their shares of HPI Preferred Stock
to HPI Common Stock prior to the Effective Time. See "THE MERGER
AGREEMENT -- The Merger."
 
    The Exchange Ratio depends on the relationship among (i) the total issued
and outstanding shares of HPI Common Stock (the "Outstanding HPI Stock")
immediately prior to the time at which the Merger becomes effective (the
"Effective Time") (including the total number of shares of HPI Common Stock
issued or issuable pursuant to the Roll-up Transactions (as described in this
Proxy Statement/Prospectus) and the conversion of all of the shares of HPI
Preferred Stock), (ii) the fair value of vested and unvested options to purchase
HPI Common Stock (the "HPI Options") outstanding immediately prior to the
Effective Time (including HPI Options issued in the Roll-up Transactions) which
will be converted in the Merger into fully paid shares of FPA Common Stock (the
"FPA Option Shares"), (iii) the presumed transaction value of $115 million and
(iv) the FPA Value. The FPA Value will be the average of the closing prices of
FPA Common Stock on the Nasdaq National Market System ("Nasdaq") for the ten
consecutive trading days ending on the date that is two trading days prior to
the date of consummation of the Merger (the "Closing Date"). The "Adjusted FPA
Value" will equal the FPA Value, except that if the FPA Value is less than $18,
the Adjusted FPA Value will be $18 and if the FPA Value is greater than $22, the
Adjusted FPA Value will be $22. Consequently, the Adjusted FPA Value may differ
from the actual market price of FPA Common Stock reported by Nasdaq on the date
of the HPI Special Meeting, the Closing Date or the date the HPI stockholders
actually receive their shares of FPA Common Stock after the Merger is completed.
See "THE MERGER -- Merger Consideration," "THE MERGER AGREEMENT -- Roll-Up
Transactions" and "-- Treatment of Stock Options."
 
    The Exchange Ratio can be represented by the following formula:
 
<TABLE>

Exchange Ratio =    ($115 Million / Adjusted FPA Value) - FPA Option Shares

                                     Outstanding HPI Stock
</TABLE>
 
    HPI believes that the Exchange Ratio will likely fall between .43 and .55
resulting in the issuance of between 5,227,273 and 6,388,889 shares of FPA
Common Stock (assuming a range of FPA Value of $15.65 to $25.00, respectively).
If the FPA Value is less than $15.65, HPI may terminate the Merger Agreement.
Except as more fully described in the accompanying Proxy Statement/Prospectus,
in no event will the number of shares of FPA Common Stock issuable in the Merger
exceed 6,388,889. The calculation of the Exchange Ratio is described more fully
in the accompanying Proxy Statement/Prospectus. See "THE MERGER -- Merger
Consideration" and "-- Adjustments to Merger Consideration."

     The following is a summary of certain information contained elsewhere or
incorporated by reference in this Proxy Statement/Prospectus. The information
contained in this summary is qualified in its entirety by, and should be read in
conjunction with, the detailed information and financial statements, including
the notes thereto, appearing elsewhere or incorporated by reference in this
Proxy Statement/Prospectus and the documents incorporated herein by reference.
 
                          FPA MEDICAL MANAGEMENT, INC.
 
     FPA is a national physician practice management company which acquires,
organizes and manages primary care physician practice networks and provides
contract management services to hospital-based emergency departments. FPA
provides primary and specialty care services to prepaid managed care enrollees
and fee-for-service patients through a network of independent practice
association physicians and owned primary care physician groups. FPA manages all
covered primary and specialty medical care for each enrollee in exchange for
monthly capitation payments pursuant to Payor contracts. Including the effects
of the Merger, FPA will be affiliated with approximately 7,580 primary care
physicians (including obstetrician-gynecologists who contract with HealthCap,
Inc. ("HealthCap") as primary care physicians, the "ob-gyn physicians") and
15,322 specialty care physicians (excluding specialists who contract with
HealthCap), who provide services to approximately 1,316,800 enrollees (including
HealthCap ob-gyn direct access enrollees) of 42 health maintenance organizations
("HMOs") or other prepaid health insurance plans (collectively, "Payors") in 27
states. FPA, through its subsidiary Sterling Healthcare Group, Inc.
("Sterling"), is also affiliated with approximately 1,300 emergency department
physicians and manages the emergency departments of 107 hospitals in 20 states.
 
     FPA's strategy is to increase enrollment by adding new Payor relationships
and new providers to the existing FPA Network and by expanding the FPA Network
into new geographic areas where the penetration of managed healthcare is
growing. FPA believes new Payor and provider relationships are possible because
of its ability to manage the cost of health care without sacrificing quality.
FPA seeks to control the two "gatekeeping" points of entry into the managed
health care delivery system -- the primary care physician's office and the
emergency room -- thereby giving FPA a platform for coordinating all aspects of
patient care under global capitation Payor contracts. FPA is also pursuing state
and national Payor contracts, which facilitate more rapid development of
provider networks in new markets and thus should enable FPA to increase
enrollment in an accelerated manner. FPA has recently entered into, or agreed to
negotiate, national Payor contracts with Aetna/U.S. Healthcare, Inc., PacifiCare
Health Systems and Foundation Health Systems, Inc.
 
     FPA's relationships with its subsidiaries and affiliated professional
corporations (the "Professional Corporations"), other providers of medical
services and Payors (collectively, the "FPA Network") offer physicians the
opportunity to participate more effectively in managed care programs by
organizing physician groups within geographic areas to contract with Payors. FPA
enhances physician practice operations by assuming administrative functions
necessary in a managed care environment. These functions include claims
adjudication, utilization management of medical services, Payor contract
negotiations, credentialing, financial reporting and the operation of management
information systems. Under these arrangements, FPA, on behalf of the
Professional Corporations, is responsible for the payment of the cost of medical
services, including professional, ancillary and medical management services, and
is entitled to amounts received from Payors in excess of such costs. FPA
believes that its management model is appealing to physicians because it allows
the physicians to retain control of their own practices while gaining access to
more patients through participation in a managed care program.
 
     Agreements with Payors and providers are entered into with, and approved
by, either a subsidiary of FPA or one of the Professional Corporations,
depending on applicable state law. Pursuant to administrative services
agreements with such subsidiaries or the Professional Corporations, payments
received from Payors are assigned to FPA.

     The FPA Network manages all covered primary and specialty medical care for
each enrollee in exchange for monthly capitation payments pursuant to Payor
contracts. Specialty care physician services, inpatient hospitalization and
certain other services managed by primary care physicians are subject to
pre-authorization guidelines and are provided through contracts negotiated by
FPA for the subsidiaries and Professional Corporations based on discounted
fee-for-service, per diem or capitation rates. Contracts with Payors and primary
care physicians generally include shared risk arrangements and other incentives
designed to encourage the provision of high-quality, cost-effective health care.
Because FPA is obligated to provide medical services, some of the costs of which
are variable, for fixed capitation fees, its profitability may vary based on the
ability of FPA and its affiliated providers to control such health care costs.
 
     FPA recruits physicians and contracts for their services to provide
staffing of emergency departments. FPA also assists its hospital clients in such
areas as physician scheduling, operations support, quality assurance and
departmental accreditation as well as billing and record keeping. In addition,
FPA has expanded its hospital-based services to include the management of
anesthesiology departments, correctional institutional health facilities and
rural health care clinics.
 
     The future growth of FPA is largely dependent on a continued increase in
the number of new enrollees in the FPA Network. This growth may come from (i)
affiliations with, or acquisitions of, individual or group physician practices
serving enrollees of Payors in the FPA Network or of new Payors, (ii) increased
membership in plans of Payors with which the Professional Corporations or
subsidiaries of FPA have contracts and whose members are patients of physicians
in the FPA Network or (iii) agreements with Payors, physicians and hospitals in
other geographic markets. The process of identifying and consummating suitable
acquisitions of, or affiliations with, physician groups can be lengthy and
complex. The environment for such acquisitions and affiliations is subject to
increasing competitive pressures. There can be no assurance that FPA will be
successful in identifying, acquiring or affiliating with additional physician
groups or hospitals or that the Professional Corporations or subsidiaries of FPA
will be able to contract with new Payors. In addition, there can be no assurance
that FPA's acquisitions will be successfully integrated on a timely basis or
that the anticipated benefits of these acquisitions will be realized; failure to
effectively accomplish the integration of acquired entities may have a material
adverse effect on FPA's results of operations and financial condition. FPA's
ability to expand is also dependent upon its ability to comply with legal and
regulatory requirements in the jurisdictions in which it operates or will
operate and to obtain necessary regulatory approvals, certificates and licenses.
 
     FPA is 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. There can be no assurance that
FPA will acquire any additional businesses.
 
     The health care industry is subject to extensive federal and state
legislation and regulation. Changes in the regulations or interpretations of
existing regulations could significantly affect the business of FPA.
 
     FPA's executive offices are located at 3636 Nobel Drive, Suite 200, San
Diego, California 92122 and its telephone number is (619) 453-1000.
 
     FPA Recent Developments. On June 30, 1997, FPA acquired HealthCap in a
stock-for-stock merger accounted for as a pooling of interests in which
2,300,000 shares of FPA Common Stock were issued in exchange for all of the
outstanding shares of HealthCap (including shares covered by HealthCap vested
options and outstanding warrants at the closing of the merger) and FPA assumed
certain outstanding HealthCap options. HealthCap is a physician practice
management company ("PPM") that provides management services to physician
networks, including IPAs and professional corporations, which are paid pursuant
to capitation arrangements. HealthCap operates in California, Florida, Georgia,
Missouri and Nevada. As of March 31, 1997, HealthCap had a network of
approximately 1,540 primary care physicians which provided health care services
to approximately 50,000 HMO enrollees under 12 Payor contracts.
 
     On March 17, 1997, FPA acquired AHI Healthcare Systems, Inc. ("AHI") in a
stock-for-stock merger accounted for as a pooling of interests in which
5,678,509 shares of FPA Common Stock were issued in exchange for all of the
outstanding shares of AHI. AHI develops integrated health care delivery networks
and
 
                                        9
<PAGE>   14
 
provides managed care infrastructure services primarily in California, Florida
and Texas. As of March 17, 1997, AHI had approximately 9,000 affiliated
physicians (including both primary care and specialist physicians) in 51
operational and 40 developing networks, which provided health care services to
approximately 200,000 enrollees under approximately 22 Payor contracts.
 
     FPA's operating revenues for the second quarter ended June 30, 1997
increased 92.3% to $244.5 million compared to $127.2 million in the same period
last year, including the operations of HealthCap, recently merged into FPA,
accounted for as a pooling of interests. Net income for the second quarter was
$8.1 million or $0.24 per share (excluding a non-recurring charge of $5.4
million related to costs associated with the merger of HealthCap) compared to a
net loss of $4.6 million or $0.16 per share for the same period last year.
Weighted average shares of FPA Common Stock outstanding were 34,259,107 and
28,317,866 for the second quarters of 1997 and 1996, respectively.
 
     For the six months ended June 30, 1997, FPA's operating revenue increased
100% to $474.6 million compared to $237.2 million in the same period last year.
Net income for the first six months of 1997 was $11.0 million or $0.32 per share
(excluding non-recurring charges of $38.0 million related to costs associated
with the HealthCap and AHI mergers) compared to a net loss of $3.6 million or
$0.13 per share for the same period last year. Weighted average shares of FPA
Common Stock outstanding were 34,510,257 and 27,660,452 for the first six months
periods of 1997 and 1996, respectively.
 
                             HEALTH PARTNERS, INC.
 
     HPI is a physician practice management company which invests in and manages
multi-specialty physician medical groups and IPAs. HPI or its affiliated medical
groups or IPAs contracts with HMOs and other Payors on a capitated or global fee
basis in selected metropolitan markets. HPI's strategy is to affiliate with
physicians who are seeking a partner to assist the medical group or network in
transitioning from a fee-for-service oriented health care system to a managed
care system. In each market, HPI seeks to affiliate with a locally prominent
medical group or IPA and assist the medical group or IPA in building a managed
care infrastructure and developing a high quality, geographically strong network
of physicians. The network is designed to increase the number of available
primary care physicians, which provides an opportunity to increase the number of
patients served under a capitated or global fee contract. HPI believes this
approach enables physicians to provide high-quality, cost-effective health care,
is highly desirable to both Payors and patients and is more likely to assist
physicians in successfully adapting to a managed care environment. HPI has
targeted major metropolitan markets with lower HMO penetration. HPI should
benefit as managed health care grows in these geographic markets by an increase
in new Payor and physician relationships.
 
     Since its inception in September 1993, HPI has affiliated with eight
physician group practices and six IPAs representing approximately 1,722
physicians in five geographic markets including the New York City metropolitan
area, northern Virginia, Washington, D.C., northern Kentucky and San Antonio,
Texas. HPI's affiliated medical groups and IPAs currently serve approximately
138,000 patients under capitated or global fee arrangements. HPI believes it is
the New York metropolitan area's largest PPM with approximately 1,331 affiliated
physicians and approximately 104,000 patients under capitated or global fee
arrangements.
 
     HPI's executive offices are located at 800 Connecticut Ave, Norwalk,
Connecticut 06854 and its telephone number is (203) 851-2600.

                                   THE MERGER
 
Effects of the Merger......  Pursuant to the Merger, Merger Sub will merge with
                             and into HPI, HPI will continue as the surviving
                             corporation (sometimes referred to as the
                             "Surviving Corporation") and HPI will become a
                             wholly owned subsidiary of FPA. At the Effective
                             Time (as defined below): (i) each outstanding share
                             of HPI Common Stock, except as provided below, will
                             be exchanged for the right to receive a number of
                             shares of FPA Common Stock equal to the Exchange
                             Ratio; (ii) each share of HPI Common Stock and HPI
                             Preferred Stock held in HPI's treasury will be
                             canceled and extinguished and will cease to exist
                             and no consideration will be delivered with respect
                             thereto; (iii) if applicable, each outstanding
                             share of HPI Common Stock and HPI Preferred Stock,
                             the holder of which is eligible for dissenters'
                             rights to appraisal in accordance with the Delaware
                             General Corporation Law ("Delaware Act"), will not
                             be converted into a right to receive shares of FPA
                             Common Stock, but such holder will be entitled to
                             only such rights as are granted under the
                             applicable provisions of the Delaware Act (see "THE
                             MERGER -- Rights of Dissenting Stockholders"); and
                             (iv) each share of capital stock of Merger Sub
                             issued and outstanding immediately prior to the
                             Effective Time will be converted into and exchanged
                             for one share of common stock of the Surviving
                             Corporation.
 
                             The Exchange Ratio will depend on the relationship
                             among (i) the total issued and outstanding shares
                             of HPI Common Stock (the "Outstanding HPI Stock")
                             immediately prior to the Effective Time (including
                             the 8,000,025 shares of HPI Common Stock to be
                             issued upon conversion of the HPI Preferred Stock
                             and the             shares of HPI Common Stock to
                             be issued in the Roll-up Transactions), (ii) the
                             fair value of options to purchase HPI Common Stock
                             (the "HPI Options") immediately prior to the
                             Effective Time (including HPI Options issued in the
                             Roll-up Transactions) which will be converted in
                             the Merger into shares of FPA Common Stock (the
                             "FPA Option Shares"), (iii) the presumed
                             transaction value of $115 million and (iv) the FPA
                             Value. The FPA Value will be the average of the
                             closing prices of FPA Common Stock on Nasdaq for
                             the ten consecutive trading days ending on the date
                             that is two trading days prior to the Closing Date.
                             The "Adjusted FPA Value" will equal the FPA Value,
                             except that if the FPA Value is less than $18, the
                             Adjusted FPA Value will be $18 and if the FPA Value
                             is greater than $22, the Adjusted FPA Value will be
                             $22. Consequently, the Adjusted FPA Value may
                             differ from the actual market price of FPA Common
                             Stock reported by Nasdaq on the date of the HPI
                             Special Meeting, the date of consummation of the
                             Merger (the "Closing Date") or the date the HPI
                             stockholders actually receive their shares of FPA
                             Common Stock after the Merger is completed. See
                             "THE MERGER -- Merger Consideration," "THE MERGER
                             AGREEMENT -- Roll Up Transactions" and

                             The Exchange Ratio can be represented by the
                             following formula:

                                       Exchange Ratio =      ($115 Million / Adjusted FPA Value) -- FPA Option Shares
                                                             ---------------------------------------------------------

</TABLE>
 
                             HPI believes that the Exchange Ratio will fall
                             between .43 and .55 (assuming a range of FPA Value
                             of $15.65 to $25.00, respectively).

                             Except as more fully described in the accompanying
                             Proxy Statement/ Prospectus, in no event will the
                             number of shares of FPA Common Stock issuable in
                             the Merger exceed 6,388,889. The adjustments to the

                             Proxy Statement/ Prospectus. IF THE FPA VALUE IS
                             LESS THAN $15.65, HPI MAY TERMINATE THE MERGER
                             AGREEMENT. See "THE MERGER AGREEMENT --
                             Termination."
 
                             The actual market price of the FPA Common Stock may
                             vary, which may cause a change in the Exchange
                             Ratio and the aggregate Merger Consideration. Each
                             HPI stockholder is urged to obtain updated FPA
                             market information.
 
                             No fractional shares of FPA Common Stock will be
                             issued in connection with the Merger and, in lieu
                             of any such fractional share, each holder of HPI
                             Common Stock who would otherwise have been entitled
                             to a fraction of a share of FPA Common Stock will
                             be entitled to receive a cash payment equal to such
                             fraction multiplied by the FPA Value.
 
Recommendation of HPI's
Board of Directors.........  The HPI Board believes that the terms of the Merger
                             are fair to and in the best interests of the
                             holders of the HPI Common Stock and HPI Preferred
                             Stock and has unanimously approved the Merger
                             Agreement and the related transactions. The HPI
                             Board unanimously recommends that HPI stockholders
                             approve the Merger Agreement. See "THE
                             MERGER -- Recommendation of the HPI Board of
                             Directors and Reasons for the Merger."
 
Opinion of HPI's Financial
Advisor....................  Smith Barney Inc. ("Smith Barney") has acted as
                             financial advisor to HPI in connection with the
                             Merger and has delivered to the HPI Board a written
                             opinion dated July 1, 1997 to the effect that, as
                             of the date of such opinion and based upon and
                             subject to certain matters stated therein, the
                             Merger Consideration was fair, from a financial
                             point of view, to the holders of HPI Common Stock.
                             The full text of the written opinion of Smith
                             Barney dated July 1, 1997, which sets forth the
                             assumptions made, matters considered and
                             limitations on the review undertaken, is attached
                             as Appendix B to this Proxy Statement/ Prospectus
                             and should be read carefully in its entirety. The
                             opinion of Smith Barney was directed to the HPI
                             Board and relates only to the fairness of the
                             Merger Consideration from a financial point of
                             view; it does not address any other aspect of the
                             Merger or related transactions and does not
                             constitute a recommendation to any stockholder as
                             to how such stockholder should vote at the HPI
                             Special Meeting. See "THE MERGER -- Opinion of
                             Financial Advisor to HPI."

                             treatment of the Merger as a "pooling of interests"
                             for financial and accounting purposes and the
                             treatment of the Merger as a tax-free

                             may be issued in the Roll-up Transactions. Either
                             FPA or HPI may extend the time for performance of
                             any of the obligations of the other party or may

                             extent material provisions or conditions are
                             waived, including, among others, the condition that
                             the Merger be treated as a "pooling of interests"
                             for accounting and financial reporting purposes and
                             that the Merger qualify as a tax-free

                             votes to the extent required by applicable law. In
                             the event the FPA Value is less than $15.65, HPI's
                             decision to complete the Merger will depend upon
                             the HPI Board's reconsideration of, among other
                             things, the factors set forth under "THE MERGER --
                             Recommendations of the HPI Board of Directors and
                             Reasons for the Merger." See "THE

                             MERGER AGREEMENT -- Conditions to the Merger."
 
Termination, Amendment and
Waiver.....................  The Merger Agreement may be terminated at any time
                             prior to the Effective Time by mutual consent of
                             FPA and HPI, or, generally, by either party if,
                             among other things, (i) the Merger shall not have
                             been completed by October 28, 1997, (ii) HPI does
                             not obtain stockholder approval, (iii) any required
                             governmental or regulatory approval is not
                             obtained, (iv) either party materially breaches any
                             of its representations, warranties or covenants
                             under the Merger Agreement or (v) the Merger is
                             prohibited by court order. In addition, HPI may
                             terminate the Merger Agreement if the FPA Value is
                             less than $15.65 or FPA has not received the
                             consent of its senior lender on or before August
                             15, 1997. Each of FPA and HPI may terminate the
                             Merger Agreement if the respective conditions to
                             each such party's obligations have not been
                             satisfied or waived on the Closing Date. See "THE
                             MERGER AGREEMENT -- Termination," "-- Amendment"
                             and "-- Waiver."
 
Rights of HPI
Stockholders...............  Both FPA and HPI are Delaware corporations and the
                             rights of their respective stockholders are
                             governed by the Delaware Act and their respective
                             Certificates of Incorporation and Bylaws. In
                             addition, the rights of the HPI stockholders are
                             affected by a Securities Purchase Agreement among
                             HPI, Foxfield Ventures, Inc. (now WellPoint),
                             Oxford and certain management investors dated as of
                             May 18, 1994 ("1994 Securities Purchase
                             Agreement"). If the Merger is consummated, HPI's
                             stockholders will become stockholders of FPA, and
                             their rights will be governed by the Certificate of
                             Incorporation and Bylaws of FPA. There are certain
                             material differences between stockholders' rights
                             under HPI's Certificate of Incorporation and Bylaws
                             and FPA's Certificate of Incorporation and Bylaws.
                             The material differences include certain
                             supermajority stockholder approval requirements
                             contained in HPI's Bylaws and the procedure for
                             nomination of directors contained in the 1994
                             Securities Purchase Agreement. See "COMPARISON OF
                             RIGHTS OF HOLDERS OF HPI AND FPA COMMON STOCK."
 
Treatment of Stock
Options....................  Pursuant to the Merger Agreement, each HPI Option,
                             whether or not vested, shall be canceled at the
                             Effective Time in exchange for a number of shares
                             of fully paid FPA Common Stock with a market value
                             equal to the fair value of such HPI Option as
                             determined by applying a variation of the
                             Black-Scholes option pricing model by an investment
                             banking firm. See "THE MERGER
                             AGREEMENT -- Treatment of Stock Options." The HPI
                             Options will include HPI Options issued in the
                             Roll-up Transactions in exchange for options to
                             acquire Minority Shares (as defined herein) in HPI
                             subsidiaries. See "THE MERGER AGREEMENT -- Roll-up
                             Transactions."
 
Roll-up Transactions.......  HPI has affiliated with group practices and IPAs
                             through subsidiaries (the "HPI Subsidiaries"). The
                             physician-owners of the group practices or IPAs own
                             shares in HPI Subsidiaries with which they contract
                             to provide health care services. In each case, such
                             shares represent less than a 30% interest in such
                             subsidiary. Such physician-owners and other
                             employees also have been granted stock options in
                             HPI Subsidiaries (the "Minority Options"). HPI has
                             the right to exchange the Minority Shares
 
                                       14
<PAGE>   19
 
                             and Minority Options for HPI Common Stock and HPI
                             Options of equal value (the "Roll-up
                             Transactions"). HPI has exercised its right in
                             connection with the Merger. Pursuant to the Roll-up
                             Transactions,           shares of HPI Common Stock
                             will be issued and                options to
                             purchase HPI Common Stock will be issued
                             immediately prior to the Effective Time. "THE
                             MERGER AGREEMENT -- Roll-up Transactions."
 
                             Following the Roll-up Transactions, the holders of

                             copy of the section of the Delaware Act relating to
                             dissenters' rights is attached to this Proxy

HSR Act Filing.............  FPA and HPI made their respective filings under the
                             HSR Act with the Federal Trade Commission ("FTC")
                             on July 29, 1997. FPA and HPI have received written
                             notification dated             , 1997, that early
                             termination of the waiting period of their
                             respective HSR Act filings has been granted.
                             Notwithstanding the termination of the waiting
                             period of the HSR Act filings, the FTC, DOJ or
                             others could take action under the antitrust laws,
                             including after the Effective Time, seeking the
                             divestiture by FPA of all or any part of the assets
                             of HPI acquired in the Merger. There can be no
                             assurance that a challenge to the Merger on
                             antitrust grounds will not be made or, if such a
                             challenge is made, that it would not be successful.
                             Although no assurance can be given, FPA and HPI
                             believe that the Merger can be effected in
                             compliance with all federal and state regulations.
                             See "THE MERGER -- Certain Regulatory Matters."
 
Material Federal Income Tax
Consequences...............  The Merger is intended to qualify for federal
                             income tax purposes as a reorganization within the
                             meaning of Section 368(a) of the Internal Revenue
                             Code of 1996 (the "Code"). Assuming the Merger so
                             qualifies as a reorganization within the meaning of
                             Section 368(a) of the Code, in general, no gain or
                             loss will be recognized by holders of HPI Common
                             Stock with respect thereto on the surrender of
                             their HPI Common Stock in exchange for FPA Common
                             Stock, except with respect to cash received in lieu
                             of fractional shares, and no gain or loss will be
                             recognized by FPA or HPI. Under the Merger
                             Agreement, it is a condition precedent to the
                             respective obligations of FPA and HPI to consummate
                             the Merger that each of FPA and HPI will have
                             received an opinion of its respective counsel,
                             dated the Closing Date, to the effect that the
                             Merger will constitute a reorganization within the
                             meaning of Sec-

                             tion 368(a) of the Code and that each of HPI, FPA
                             and Merger Sub will be a party to the
                             reorganization within the meaning of Section 368(b)
                             of the Code. For a further discussion of the
                             federal income tax consequences of the Merger see
                             "THE MERGER -- Certain Federal Income Tax
                             Consequences." EACH HPI STOCKHOLDER IS URGED TO
                             CONSULT HIS OR HER PERSONAL TAX AND FINANCIAL
                             ADVISORS CONCERNING THE FEDERAL INCOME TAX
                             CONSEQUENCES OF THE MERGER, AS WELL AS ANY
                             APPLICABLE STATE, LOCAL, FOREIGN OR OTHER TAX
                             CONSEQUENCES, BASED UPON SUCH HOLDER'S PARTICULAR
                             FACTS AND CIRCUMSTANCES.
 
Accounting Treatment.......  The Merger will be treated as a "pooling of
                             interests" for accounting and financial reporting
                             purposes. See "THE MERGER -- Accounting Treatment."
 
Interests of Certain
Persons in the Merger;
Possible Conflicts of
Interest...................  In considering the recommendations of the HPI Board
                             of Directors with respect to the Merger Agreement
                             and the transactions contemplated thereby, HPI
                             stockholders should be aware that certain members
                             of HPI management and the Board of Directors have
                             interests in the Merger that are in addition to the
                             interests of the stockholders of HPI generally.
                             These interests arise from, among other things,
                             certain employment agreements, management retention
                             programs, indemnification arrangements,
                             registration rights and other matters which FPA
                             will assume or has agreed to provide after the
                             Merger. See "THE MERGER -- Interests of Certain

                             no assurance of successful integration of certain

                             Stock entitled to 188 votes per share, with respect
                             to all matters to be considered at the HPI Special
                             Meeting.
Security Ownership of HPI
  Management...............  As of the record date, the directors and named
                             executive officers of HPI as a group owned
                             approximately 10.60% of the voting power
                             represented by the HPI Voting Securities.
                             Stockholders of HPI with the collective power to
                             vote approximately 82.70% of the HPI Voting
                             Securities have entered into voting agreements and
                             given their irrevocable proxies to FPA, providing
                             that their shares shall be voted in favor of the
                             Merger Agreement. Accordingly, approval of the
                             Merger by the HPI stockholders is assured. See "THE
                             MERGER -- Interests of Certain Persons in
 
                                       18

                             the Merger" and "SECURITY OWNERSHIP OF CERTAIN
                             BENEFICIAL OWNERS AND MANAGEMENT -- HPI."
 
Reasons for the Merger.....  The Board of Directors of HPI, after careful
                             consideration, has unanimously approved the Merger
                             Agreement and the transactions contemplated thereby
                             and determined that the Merger is fair to, and in
                             the best interests of, HPI and its stockholders and
                             recommends a vote FOR the approval and adoption of
                             the Merger Agreement.
 
                             The HPI Board believes the Merger offers HPI an
                             attractive opportunity to strengthen its
                             competitive position and enhance its profile with
                             physicians and Payors. Furthermore, the Merger will
                             allow HPI to align with a leading PPM in a
                             consolidating industry while at the same time
                             affording stockholders enhanced liquidity due to
                             the developed market for FPA's publicly traded
                             shares. Disadvantages include the possibility that
                             FPA will not be able to integrate successfully
                             recent acquisitions, the possibility that FPA will
                             not be able to sustain its growth strategy and
                             FPA's leveraged balance sheet. See "THE MERGER --
                             Recommendation of the HPI Board of Directors and
                             Reasons for the Merger."

     The following table sets forth certain historical per share data of FPA and
combined per share data of FPA and HPI on an unaudited pro forma basis, based on
the assumption that the Merger occurred at the beginning of the earliest period
presented and was accounted for as a pooling of interests. Historical financial
data of FPA has been restated to include the effects of the October 1996 merger
with Sterling and the March 1997 merger with AHI, both of which were accounted
for as a "pooling of interests." Historical net earnings per common share of HPI
have not been presented as HPI is a nonpublic company. The pro forma comparative
per share data gives effect to the Merger assuming the issuance of 5,227,273
shares of FPA Common Stock in the Merger. See "THE MERGER -- Adjustments to
Merger Consideration."

(1) Prices have been adjusted to reflect a 100% stock dividend of FPA Common
Stock effected April 1995.
 
     The closing price of FPA Common Stock on the Nasdaq on July 1, 1997, the
last full trading day prior to the public announcement of the Merger Agreement,
was $23.875 and on             , 1997 was $          .
 
     FPA declared no dividends during 1995, 1996 or 1997 and has no plans to
declare cash dividends in the foreseeable future. FPA's Credit Agreement with
Lehman Commercial Paper, Inc. and the lenders parties thereto and FPA's 6 1/2%
Convertible Subordinated Debentures limit the ability of FPA to pay cash
dividends.
 
     As of the HPI record date, there were 17 holders of record of HPI Common
Stock, one holder of record of HPI's Series A Convertible Preferred Stock and
one holder of record of HPI's Series B Convertible Preferred Stock.
 
     HPI declared and paid a dividend on its Series A Convertible Preferred
Stock in May 1994 in connection with its exchange into Series B Convertible
Preferred Stock. Also, HPI had a stock split distributed as a dividend to its
common stockholders in May 1994. See Note 9 of Notes to HPI's Consolidated
Financial Statements contained elsewhere in this Proxy Statement/Prospectus.

                                  RISK FACTORS
 
     In addition to other information in this Proxy Statement/Prospectus, the
following factors should be considered carefully in evaluating the proposals to
be voted on at the HPI Special Meeting.
 
RISKS RELATING TO FPA
 
     No Assurance of Successful Integration of Acquisitions; Expanded Service
Offering. Over the last two and one-half years, FPA has pursued an aggressive
growth strategy. FPA's growth has been achieved primarily through acquisitions,
several of which have been completed during the last six months. Several of
these acquisitions are large transactions which involve significant risks and
uncertainties for FPA. FPA intends to continue to pursue growth through
acquisitions. The success of past and future acquisitions is largely dependent
on the ability of FPA to integrate the operations of the acquired companies into
FPA's operations in an efficient and effective manner. 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 and geographically expanded
entity, presents a significant challenge to FPA's management. In addition,
integration must be carried out so that FPA is able to control medical and
administrative costs. The ability to control such costs is key to the successful
future operations of FPA. There can be no assurance that FPA's acquisitions will
be successfully integrated on a timely basis 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. FPA 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 FPA's results of operations and financial
condition.
 
     Certain of the companies recently acquired by FPA 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." FPA has commenced the institution of certain measures
intended to reduce these losses and quarterly fluctuations and to operate the
acquired businesses profitably. However, there can be no assurance that FPA will
reverse these trends or operate these entities profitably. If there are
continuing operating losses at the acquired companies, FPA may need additional
capital to fund its business, and there can be no assurance that such additional
capital can be obtained or, if obtained, it will be on terms acceptable to FPA.
 
     FPA is 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
FPA's ability to compete successfully at favorable prices for available
acquisition candidates or to complete future acquisitions, or as to the
financial effect on FPA of any acquired business. Future acquisitions by FPA 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 FPA's future operating results.
 
     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 FPA Network to new Payors and providers with which it has had no
previous business experience. FPA cannot predict whether it will be able to
enroll into the FPA 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 FPA's operating results.
 
     In addition, as a result of the acquisition of Sterling, FPA offers new
services, specifically the management and support of hospital-based emergency
departments. The addition of these new services presents certain risks and
uncertainties due to FPA's relative unfamiliarity with these types of services
and the
 
                                       22
<PAGE>   27
 
market for such services. There can be no assurance that FPA will be successful
in developing and integrating Sterling's operations and services.
 
     Risks of Financial Leverage. FPA's indebtedness is significant in relation
to its stockholders' equity. On a pro forma basis (excluding the effects of the
Merger) giving effect to amounts drawn down pursuant to FPA's $275 Million
Credit Agreement (including the term loan) with Lehman Commercial Paper, Inc.,
as Administrative Agent for the Lenders parties thereto dated June 30, 1997 (the
"Credit Agreement") and the issuance of FPA's 6 1/2% Convertible Subordinated
Debentures due 2001 (the "Debentures") in December 1996, FPA's indebtedness
accounts for approximately 240% of FPA's stockholders' equity as of June 30,
1997. While FPA believes it will be able to service its debt, there can be no
assurance to that effect. The degree to which FPA is leveraged could affect its
ability to service its indebtedness, make capital expenditures, respond to
market conditions and extraordinary capital needs, take advantage of certain
business opportunities or obtain additional financing. Unexpected declines in
FPA's future business, or the inability to obtain additional financing on terms
acceptable to FPA, if required, could impair FPA's ability to meet its debt
service obligations or fund acquisitions and, therefore, could materially
adversely affect FPA's business and future prospects.
 
     Growth Strategy; Difficulty in Maintaining Growth. The future growth of FPA
is largely dependent on a continued increase in the number of new enrollees in
the FPA Network. This growth may come from (i) affiliations with, or
acquisitions of, individual or group physician practices serving enrollees of
Payors in the FPA Network or of new Payors, (ii) increased membership in plans
of Payors with which the Professional Corporations have contracts and whose
members are patients of physicians in the FPA Network or (iii) agreements with
Payors, physicians and hospitals in other geographic markets. The process of
identifying and consummating suitable acquisitions of, or affiliations with,
physician groups can be lengthy and complex. The marketplace for such
acquisitions and affiliations is subject to increasing competitive pressures.
There can be no assurance that FPA will be successful in identifying, acquiring
or affiliating with additional physician groups or hospitals or that the
subsidiaries and Professional Corporations will be able to contract with new
Payors. In addition, there can be no assurance that FPA's acquisitions will be
successfully integrated on a timely basis or that the anticipated benefits of
these acquisitions will be realized; failure to effectively accomplish the
integration of acquired entities may have a material adverse effect on FPA's
results of operations and financial condition. FPA's ability to expand is also
dependent upon its ability to comply with legal and regulatory requirements in
the jurisdictions in which it operates or will operate and to obtain necessary
regulatory approvals, certificates and licenses.
 
     Risks Related to Intangible Assets. As a result of FPA's various
acquisition transactions, intangible assets of approximately $301 million have
been recorded as of March 31, 1997 on FPA's balance sheet. Such intangible
assets totaled approximately 258% of FPA's stockholders' equity as of March 31,
1997. Using amortization periods ranging from four to 30 years (with an average
amortization period of approximately 29 years), amortization expense relating to
such intangible assets will be approximately $10 million per year. Further
acquisitions that result in the recognition of additional intangible assets
would cause amortization expense to further increase. A portion of the
amortization generated by these intangible assets is not deductible for tax
purposes.
 
     At the time of, or following each acquisition, FPA evaluates each
acquisition and establishes an appropriate amortization period based on the
underlying facts and circumstances. Subsequent to such initial evaluation, FPA
periodically reevaluates such facts and circumstances to determine if the
related intangible asset continues to be realizable and if the amortization
period continues to be appropriate. As the underlying facts and circumstances
subsequent to the date of acquisition can change, there can be no assurance that
the value of such intangible assets will be realized by FPA. In the past, FPA
has recorded charges for impairment of goodwill, including (i) in 1995, $434,000
related to the sale and closing of primary care centers and (ii) in 1996, $4.1
million as a result of a 1995 acquisition in Arizona and $14.8 million related
to termination of emergency room department contracts. Although at March 31,
1997 the net unamortized balance of intangible assets acquired was not
considered to be impaired, any future determination that a significant
impairment has occurred would require the write-off of the impaired portion of
unamortized intangible assets, which could have a material adverse effect on
FPA's results of operations.

     Difficulty in Controlling Health Care Costs; Capitated Nature of
Revenue. Agreements with Payors typically provide for the Professional
Corporations to receive prepaid monthly fees per enrollee known as "capitation"
payments. FPA's profitability primarily depends upon its ability to control
costs and the ability of the subsidiaries and Professional Corporations to incur
less in medical, hospital and administrative costs than the capitation revenue
received from Payors. Such profitability is achieved through effective
management of the provision of medical services by physicians in the FPA
Network, including controlling utilization of specialty care physicians and
other ancillary providers, purchasing services from physicians outside the FPA
Network at competitive prices and negotiating favorable rates with hospitals.
Agreements with Payors 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 be assumed by FPA,
thereby reducing FPA's net income. The amount of non-capitated medical and
hospital costs in any period could be affected by factors beyond the control of
the FPA Network, such as changes in treatment protocols, epidemics, disasters,
new technologies and inflation. To the extent that specialty care physicians'
fees or hospital costs have not been capitated and enrollees require more
specialty care than anticipated or have higher than anticipated hospital
utilization rates, revenue paid to the FPA Network by Payors may not be
sufficient to cover the costs the FPA Network is obligated to pay. FPA purchases
stoploss insurance protection which provides thresholds or "attachment points,"
generally $100,000 for inpatient services per year, at which substantially all
financial exposure for inpatient services of an enrollee beyond such threshold
is contractually shifted to the insurer up to a specified level (generally $1
million for inpatient services), at which point the risk of loss returns to FPA.
The failure of FPA to negotiate favorable attachment points in the future could
have a material adverse effect on FPA's financial condition, results of
operations and/or liquidity. There can be no assurance that FPA will be able to
negotiate favorable attachment points in the future.
 
     Risks Related to Full Risk Capitation. Under capitation contracts
generally, Professional Corporations accept capitation payments and, as a
result, accept the financial risk for the provision of health care services,
including those not normally performed and provided by professional corporations
comprised of primary care physicians under payor contracts (e.g., specialty care
physician services). Under substantially all Payor contracts, the subsidiaries
and Professional Corporations accept the financial risk for the provision of
outpatient medical services ("fully delegated" contracts). Under certain Payor
contracts, a Professional Corporation also accepts the financial risk for
hospital services. Approximately 26% of FPA's total operating revenue for the
year ended December 31, 1996 was generated from contracts in which the
subsidiaries and Professional Corporation accepted the financial risk for
outpatient medical and hospital services. In the event that (i) FPA is unable to
negotiate favorable prices or rates in contracts with providers of these
services on behalf of the subsidiaries and Professional Corporations, (ii) a
significant number of enrollees require services up to the stoploss insurance
"attachment points" or (iii) the subsidiaries and Professional Corporations are
unable to control effectively the utilization of these services, FPA could
experience material adverse effects on its results of operations.
 
     Risks Related to Fee-for-Service Contracts. FPA's subsidiary, Sterling,
provides physician practice management services to hospitals under
fee-for-service contracts and flat-rate contracts. In general, under fee-
for-service contracts, Sterling's revenue is derived from amounts billed to
patients and collected for the account of Sterling. In contrast, under flat-rate
contracts Sterling's revenue is derived from payments of negotiated amounts paid
by the hospital. Under fee-for-service contracts, Sterling accepts
responsibility for billing and collection, and consequently assumes the
financial risks related to changes in patient volume, payor mix and third party
reimbursement rates. Any change in reimbursement policies and practices, payor
mix, patient volume or covered services could materially adversely affect the
operations of FPA, particularly under fee-for-service contracts. Sterling's
fee-for-service contractual arrangements also involve a credit risk related to
uncollectibility of accounts. In addition, fee-for-service contracts have less
favorable cash flow characteristics than flat-rate contracts due to longer
collection periods. Failure to manage adequately the collection risks and
working capital demands associated with fee-for-service contracts could have a
material adverse effect on FPA.

     Dependence on Government and Other Third Party Payors. As a result of the
Sterling acquisition, a significant portion of FPA's operating revenue will be
derived from payments made by government-sponsored health care programs as well
as from other third party payors. For the year ended December 31, 1996, giving
effect to the Sterling and AHI mergers, approximately 34% of FPA's revenue was
derived from government Payors. The Medicare and Medicaid programs are subject
to substantial regulation by the federal and state governments, which are
continually revising and reviewing the programs and their regulations. In
addition, funds received under these programs are subject to audit with respect
to the proper billing for physician services and, accordingly, retroactive
adjustments of revenue from these programs may occur. While FPA seeks to comply
with applicable Medicare and Medicaid reimbursement regulations, there can be no
assurance that FPA would be found to be in compliance with such regulations
should it be subject to audit. Continuing budgetary constraints at both the
federal and state level and the rapidly escalating costs of health care and
reimbursement programs have led, and may continue to lead, to significant
reductions in government and other third party reimbursements for certain
medical charges and to the negotiation of reduced contract rates or capitated or
other financial risk-shifting payment systems by third party payors with service
providers. Both the federal government and various states are considering
imposing limitations on the amount of funding available for various health care
services. In recent years, the U.S. Congress has considered various budget
proposals intended to reduce the rate of increase in Medicare and Medicaid
expenditures through cost savings and other measures. Congress passed a fiscal
year 1996 budget reconciliation bill, which, although ultimately vetoed by the
President, called for reductions in the rate of spending increases in the
Medicare and Medicaid programs over the next seven years. Currently pending in
Congress is proposed Medicare legislation which includes provisions that would
(i) increase the age of eligibility for Medicare benefits, (ii) raise Medicare
premiums to those Medicare beneficiaries with incomes above a certain level and
(iii) reduce payments to physicians and hospitals. FPA cannot predict the effect
that current and future proposals regarding government funded programs would
have on its operations. Additionally, Resource Based Relative Value Scale
("RBRVS"), a system of reimbursement designed to reallocate medical
reimbursement among medical specialties, took effect on January 1, 1992 and has
been phased in over a four year period. Under the regulations relating to the
RBRVS fee structure, the aggregate fee payments from Medicare for certain
emergency department procedures may be reduced in some circumstances. There can
be no assurance that the payments under governmental and private third party
payor programs will remain at levels comparable to present levels or will be
sufficient to cover the costs allocable to patients eligible for reimbursement
pursuant to such programs. Furthermore, changes in reimbursement regulations,
policies, practices, interpretations or statutes that place material limitations
on reimbursement amounts or practices could adversely affect the results of
operations of FPA.
 
     Reliance on Certain Payors. For the years ended December 31, 1994 and 1995,
CareAmerica of Southern California, Inc. ("CareAmerica") accounted for 11.3% and
26.2% of FPA's operating revenue, respectively. For the year ended December 31,
1996, CareAmerica and Foundation Health Systems, Inc. ("Foundation") accounted
for 16.1% and 11.3%, respectively, of FPA's operating revenue.
 
     Terminability of Payor Contracts. Contracts with Payors generally provide
for terms of one to thirty years, may be terminated earlier without cause, upon
notice and upon renewal or in a number of other circumstances and are subject to
negotiation of capitation rates, covered benefits and other terms and
conditions. At times, Payor contracts may be continued on a month-to-month basis
while the parties renegotiate the terms of the contracts. Agreements with
hospitals to provide contract management services generally have terms of one or
two years and are renewable automatically unless either party gives written
notice of its intent not to renew at least 90 days prior to the end of the term.
Many of these agreements provide for termination by the hospital without cause
on relatively short notice. There can be no assurance that any of such contracts
will not be terminated early, will be renewed or that they will contain
favorable terms. Since January 1994, a number of Sterling's hospital services
agreements have been terminated as a result of nonrenewal, termination by the
hospital, termination by Sterling or hospital closure. Future consolidation in
the health care industry may result in future hospital services agreements being
terminated. The loss of any Payor or hospital contract and the failure to regain
or retain such Payor's members or the related revenues without entering into new
Payor relationships or hospital contracts could have a material adverse effect
on FPA's results of operations.
 
                                       25
<PAGE>   30
 
     As of June 30, 1997, approximately 33% of FPA's membership was pursuant to
Payor agreements with Foundation. The terms of these Payor agreements are thirty
years with automatic five-year renewal periods. These agreements commit certain
Professional Corporations, among other things, to contract with Foundation for
all benefit programs and to maintain sufficient medical personnel to provide
reasonable and adequate access to professional services for all benefit programs
offered by Foundation, to keep care centers open given specified levels of
patients and to agree to certain pricing and contracting parameters with
Foundation. The agreements may be terminated in a number of circumstances,
including the event of a material breach or a violation of applicable laws,
rules or regulations. The termination of such agreements would have a material
adverse effect on FPA's results of operations.
 
     Dependence on Primary Care Physicians and Emergency Medicine
Physicians. Primary care physicians are an integral part of the FPA Network, as
they provide and manage medical services offered to enrollees. FPA's growth
depends, in part, on its ability to retain existing and attract additional
primary care physicians to the FPA Network. There can be no assurance that
physicians presently in the FPA Network will not leave the FPA Network, that FPA
will be able to attract additional primary care physicians into the FPA Network
or that the amount of capitation or fee-for-service payments to physicians will
not have to be increased. To the extent that primary care physicians leave the
FPA Network or capitation or fee-for-service payments to physicians are
increased, FPA's results of operations may be materially adversely affected. In
order to provide management services to hospital emergency departments, FPA must
recruit and retain sufficient numbers of qualified physicians. There is a
substantial shortage of board certified emergency medicine physicians, and FPA
competes with many types of health care providers, as well as teaching, research
and governmental institutions, for the services of such physicians. An inability
to recruit and retain emergency medicine physicians could adversely affect FPA's
adding new and retaining existing hospital clients.
 
     On December 5, 1996, the Thomas-Davis Medical Centers, P.C. ("TDMC")
physicians located in Tucson, Arizona voted to be represented by the Federation
of Physicians and Dentists. On February 13, 1997, the TDMC employees located in
Tucson voted to be represented by the Union of Health and Hospital Care
Employees. TDMC and FPA are in the process of appealing certain aspects related
to such representation; however, there can be no assurance as to the outcome of
such appeals. Although FPA does not expect union affiliations of its Arizona
employees to have a material adverse effect on its results of operations or
financial condition, there can be no assurance that future affiliations and/or
collective bargaining arrangements will not have a material adverse effect on
FPA's results of operations.
 
     Risks Related to Classification of Physicians as Independent
Contractors. FPA's subsidiary, Sterling, generally contracts with emergency room
physicians as independent contractors to provide services to its hospital
clients. These independent contractor physicians are paid on an hourly basis.
Pursuant to such compensation arrangements, independent contractor physicians do
not share in the profit derived by FPA from FPA's operations. Because FPA
regards its contracted physicians as independent contractors and not as
employees, FPA does not withhold federal or state income taxes, make federal or
state unemployment tax payments or provide workers' compensation insurance for
such physicians. There can be no assurance that federal or state taxing
authorities or other parties will not challenge the classification of such
independent contractor physicians and determine that such physicians should be
classified as employees. In the event that the physicians under contract with
FPA are determined to be employees, FPA's results of operations will be
materially and adversely affected and may be subject to retroactive taxes and
penalties.
 
     State Laws Regarding Prohibition of Corporate Practice of Medicine. In
certain states in which FPA conducts or may conduct business, 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 corporate practice of medicine refers to the
rendering directly, or through employment, of medical services by a general
business corporation. As stated in the Notes to its Consolidated Financial
Statements incorporated herein by reference, FPA believes that it has perpetual
and unilateral control over the assets and operations of the various affiliated
Professional Corporations. There can be no assurance that regulatory authorities
will not take the position that such control conflicts with state laws regarding
the corporate practice of medicine or other federal or state restrictions.
Although FPA believes its operations as currently conducted are in material
compliance with existing applicable laws, there can be no assurance that
 
                                       26
<PAGE>   31
 
the existing organization of FPA and its contractual arrangements with
affiliated physicians will not be successfully challenged in such states as
constituting the unlicensed practice of medicine or that the enforceability of
the provisions of such arrangements, including non-competition agreements, will
not be limited. In the event of action by any regulatory authority limiting or
prohibiting FPA from carrying on its business or from expanding the operations
of FPA to certain jurisdictions, structural and organization modifications of
such organization or arrangements may be required, which could have an adverse
effect on FPA.
 
     Because certain state laws prohibit general business corporations from
controlling professional corporations contractually or otherwise, FPA has
structured its contracts with the Professional Corporations so that such
corporations retain the right to enter into contracts for the provision of
medical services or make other financial commitments. Such contracts allow the
Professional Corporations to make commitments which could be on terms which may
not be advantageous to FPA. For example, a Professional Corporation could
decline to enter into Payor contracts which are negotiated for it by FPA or,
alternatively, could decide to enter into Payor contracts which FPA does not
believe are financially advantageous. Physicians who contract with these
corporations may also have the legal right to decline to use other physicians in
the FPA Network or specialists having a pre-existing, subcapitated or fixed fee
relationship with the FPA Network. These decisions, if made by a Professional
Corporation or a physician, could have a material adverse effect on FPA's
business and results of operations.
 
     Possible Negative Effects of Prospective Health Care Reform. Various plans
have been proposed and are being considered on federal, state and local levels
to reduce costs in health care spending. Although FPA believes its management
model responds to the concerns addressed by such plans, it is not possible to
assess the likelihood any of these proposals will be enacted or to assess the
impact any of these proposals may have on reimbursement to health care
providers. Any plan to control health care costs, however, could result in lower
rates of reimbursement. Lower rates of reimbursement may reduce the amount
ultimately received by FPA and, accordingly, may have a material adverse effect
on FPA's business and results of operations.
 
     In recent years, legislation has been proposed in Congress to implement an
"any willing provider" law on a national level. These laws, which are in effect
in some states, require managed care organizations, such as HMOs, to contract
with any physician who is appropriately licensed and who meets any applicable
membership criteria. Such laws could limit the flexibility of managed care
organizations to achieve efficiency by controlling the size of their primary
care provider networks and the number of specialty care providers to whom
enrollees are referred. At present, no state in which FPA Network physicians
practice has such a law although "any willing provider" laws have been proposed
in states in which FPA operates. FPA cannot predict what effect such laws would
have on its operations.
 
     Possible Negative Effects of Governmental Regulations. The health care
industry is subject to extensive federal and state regulation. Changes in the
regulations or reinterpretations of existing regulations may significantly
affect the FPA Network. FPA and the Professional Corporations are 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. Noncompliance with the federal anti-kickback
legislation can result in exclusion from the Medicare and Medicaid programs and
civil and criminal penalties. The federal government has promulgated "safe
harbor" regulations that identify certain business and payment practices which
are deemed not to violate the federal anti-kickback statute. In addition,
federal legislation currently restricts the ability of physicians to refer
Medicare or Medicaid patients to certain entities in which they have an
ownership interest or compensation arrangement for health care services,
including clinical laboratory services. With respect to the self-referral
prohibitions, the entity and the referring physician are prohibited from
receiving Medicare or Medicaid reimbursement for services rendered and civil
penalties may be assessed. Many states, including states in which FPA does
business, have similar anti-kickback and anti-referral laws. Penalties similar
to those imposed by federal law are provided for violation of state anti-
kickback and anti-referral laws. FPA believes that its operations comply with
all applicable anti-kickback and anti-referral laws. In addition, health care
reforms may expand existing anti-kickback and anti-referral laws to apply to all
health care payors, not just Medicare and Medicaid. It is unclear how any reform
legislation would
 
                                       27
<PAGE>   32
 
affect health care provider networks or other types of managed care
arrangements. There can be no assurance that FPA will be able to comply with any
new laws.
 
     Furthermore, a number of states prohibit sharing professional fees (or fee
splitting) with anyone other than a member of the same profession. There can be
no assurance that such laws will ultimately be interpreted in a manner
consistent with the practices of FPA.
 
     Federal and state laws regulate insurance companies, HMOs and other managed
care organizations. Many states also regulate the establishment and operation of
networks of health care providers. Generally, these laws do not apply to the
hiring and contracting of physicians by other health care providers. There can
be no assurance that regulators of the states in which FPA operates would not
apply these laws to require licensure of FPA's operations as an HMO, an insurer
or a provider network. FPA believes that it is in compliance with these laws in
the states in which it does business, but there can be no assurance that
interpretations of these laws by the regulatory authorities in these states or
in the states in which FPA may expand will not require licensure or a
restructuring of some or all of FPA's operations. In the event that FPA is
required to become licensed under these laws, the licensure process can be
lengthy and time consuming and, unless the regulatory authority permits FPA to
continue to operate while the licensure process is progressing, FPA could
experience a material adverse change in its business while the licensure process
is pending. In addition, many of the licensing requirements mandate strict
financial and other requirements which FPA may not be able to meet. Further,
once licensed, FPA would be subject to continuing oversight by and reporting to
the respective regulatory agency.
 
     Although under the laws of most states the business of insurance generally
is defined to include the acceptance of financial risk and has not extended to
physician networks, the Knox-Keene Health Care Service Plan Act of 1975, as
amended (the "Knox-Keene Act"), a California statute that applies to managed
care health service plans, requires all health care service plans to be licensed
by the California Department of Corporations (the "Department"). The Department
has determined that physician management companies like FPA must apply for and
operate under a restricted Knox-Keene license. FPA's restricted license
application was approved by the Department in December 1996. The loss or
revocation of such license would have a material adverse effect on FPA's
business and results of operations.
 
     In addition, there can be no assurance that regulatory authorities in the
other states in which FPA or its affiliates operate will not impose similar
requirements or that future interpretations of insurance laws and health care
network laws by the regulatory authorities in these states or other states will
not require licensure or a restructuring of some or all of the operations of
FPA.
 
     The National Association of Insurance Commissioners ("NAIC") recently
adopted the Managed Care Plan Network Adequacy Model Act (the "Model Act") which
is intended to establish standards for the creation and maintenance of networks
by health carriers and establish requirements for written agreements between
health carriers offering managed care plans, participating providers and
intermediaries, like FPA, which negotiate provider contracts, regarding the
standards, terms and provisions under which a participating provider will
provide services to covered persons. An NAIC model insurance act does not carry
the force of law unless it is adopted by applicable state legislatures. FPA does
not know which states, if any, will adopt the Model Act. There can be no
assurance that FPA will be able to comply with the Model Act if it is adopted in
any state in which FPA does business.
 
     Antitrust Regulation. FPA's affiliated IPAs and Professional Corporations
are separate legal entities due to legal and regulatory requirements; if they
are deemed to be competitors in specified markets, they may be subject to
various laws which prohibit anti-competitive conduct, including price fixing,
concerted refusals to deal and division of market. Alternatively, if FPA's
affiliated IPAs and Professional Corporations, although separate entities, are
deemed to be part of a single entity or system, they may be subject to laws that
prohibit anti-competitive combinations or activities if the number of affiliated
physicians in specified markets exceeds certain thresholds. FPA believes that it
is in compliance with the antitrust laws, but there can be no assurance that
FPA's interpretation is consistent with that of federal or state authorities or
courts or that such circumstances will remain as FPA grows and matures and as
further regulations and interpretations are promulgated.
 
                                       28
<PAGE>   33
 
     Competitive Market Forces. The managed care industry is highly competitive
and is subject to continuing changes in how services are provided and how
providers are selected and paid. Increased enrollment in prepaid health care
plans because of health care reform or for other reasons, increased
participation by physicians in group practices and other factors may attract
entrants into the physician practice management services segment of the managed
care industry and result in increased competition for FPA. In addition, local
physician groups and hospitals are also trying to combine their services into
integrated delivery networks. Certain of FPA's competitors are significantly
larger and better capitalized, provide a wider variety of services, may have
greater experience in providing physician practice management services and may
have longer established relationships with Payors. Accordingly, FPA may not be
able to continue to increase the number of providers in the FPA Network,
negotiate contracts with new Payors on behalf of the Professional Corporations
or renegotiate favorable contracts with current Payors. The inability of FPA to
increase the number of providers in the FPA Network and negotiate favorable
contracts with Payors could have a material adverse effect on FPA.
 
     In addition, as a result of consolidations among Payors, certain Payors are
able to negotiate or are in the process of negotiating significant reductions in
the capitation payments to providers. Further, certain Payors have deleted
shared risk arrangements from their contracts with providers thereby decreasing
the amount of compensation such Payors are paying providers. To date, none of
the Payors has deleted shared risk arrangements from its contract with any
Professional Corporations. If Payors negotiate cost reductions with such
Professional Corporations or eliminate shared risk arrangements in which the
Professional Corporations are currently participating, such actions could have a
material adverse effect on FPA's results of operations.
 
     Potential Liabilities. In recent years, physicians, hospitals and other
participants in the managed health care industry have become subject to an
increasing number of lawsuits alleging medical malpractice as well as 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. FPA is named in such lawsuits and claims and will likely be named as a
party in similar suits and claims in the future. FPA maintains an errors and
omissions policy relating to its utilization review activities and is included
as a named or additional insured on the policies of the Professional
Corporations. Insurance coverage for lawsuits brought or which may be brought
against FPA may not be sufficient to cover FPA's expenses or losses. There can
be no assurance that insurance coverage will be sufficient and, if insufficient,
that such suits or claims will not have a material adverse effect on FPA.
Furthermore, FPA could be held liable for the negligence of a contracted health
care professional if such health care professional were regarded as an employee
or agent of FPA in the practice of medicine. In addition to any potential tort
liability of FPA, FPA's emergency department contracts with hospitals generally
contain provisions under which FPA agrees to indemnify the hospital for losses
resulting from the malpractice of contracted physicians.
 
     An increasing number of health care providers and other entities are
parties to lawsuits alleging fraudulent billing practices under the federal
Civil False Claims Act. The Civil False Claims Act permits a person (generally
an employee or former employee of the health care provider or other entity) to
assert the rights of the government by initiating a qui tam action against a
health care provider or other entity if such person has or purports to have
information that the health care provider or other entity falsely and
fraudulently submitted a claim to the government for payment. Upon filing, the
government has the opportunity to intervene and assume control of the case.
Penalties of up to $10,000 for each false or fraudulent claim presented to the
government for payment may be awarded as well as treble damages. Defendants also
may be excluded permanently or for a period of time from participation in the
Medicare and Medicaid programs. Because of penalties and treble damages, many of
these lawsuits involve large monetary claims and substantial defense costs. If a
qui tam action is successfully prosecuted, no assurance can be made that such
event would not have a material adverse effect on FPA and its operations.
 
     AHI is a defendant in a class action securities lawsuit entitled In re AHI
Healthcare Systems, Inc. Securities Litigation filed in the United States
District Court for the Central District of California, Western Division. The
suit was initially filed on December 20, 1995 against AHI, certain of its
officers and directors, and all of the underwriters of AHI's common stock in
AHI's initial public offering. The suit asserts that AHI artificially inflated
the price of its stock by, among other things, misleading securities analysts
and by failing to
 
                                       29
<PAGE>   34
 
disclose in its initial public offering prospectus alleged difficulties with the
acquisition of Lakewood Health Plan, Inc. and with two of AHI's Payor contracts
with FHP, Inc. The plaintiffs seek unspecified damages on behalf of the
stockholders who purchased AHI's common stock between September 28, 1995 and
December 19, 1995. On January 17, 1997 the district court (i) granted AHI's
motion for partial summary judgment and dismissed the class plaintiffs' claims
concerning the alleged misrepresentations regarding AHI's intended use of
initial public offering proceeds and AHI's relationship with FHP, Inc. but (ii)
denied summary judgment on the claims relating to the proposed acquisition of
Lakewood Health Plan, Inc. As a result, only those claims relating to Lakewood
Health Plan and AHI's alleged liability for the public statements of securities
analysts following AHI remain in the suit. Since the court's ruling on AHI's
motion for partial summary judgment, the plaintiffs have asked the court for
leave to amend their complaint to add an additional claim alleging problems with
AHI's medical group operations in Downey, California. FPA intends to vigorously
defend this lawsuit and does not expect that the outcome of this lawsuit will
have a material adverse effect on FPA's results of operation.
 
     Fluctuations in Quarterly Results. FPA's financial statements (including
interim financial statements) contain accruals which are calculated quarterly
for estimates of amounts assigned by certain FPA subsidiaries and the
Professional Corporations to FPA and paid by Payors based upon hospital
utilization ("shared risk revenues"). Quarterly results have in the past and may
in the future be affected by adjustments to such estimates for actual costs
incurred. Historically, certain FPA subsidiaries and the Professional
Corporations and Payors generally reconcile differences between actual and
estimated amounts receivable or payable relating to Payor shared risk
arrangements in the second or third quarter of each year. In the event that
certain FPA subsidiaries and the Professional Corporations and Payors are unable
to reconcile such differences, extensive negotiation, arbitration or litigation
relating to the final settlement of these amounts may occur. To the extent that
the FPA Network expands to include additional Payors, the timing of these
adjustments may vary; this variation in timing may cause FPA's quarterly results
not to be directly comparable to corresponding quarters in other years. FPA'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 FPA at
the time of calculation, actual costs may differ from FPA's estimates of such
amounts. If the actual costs differ significantly from the amounts estimated by
FPA, adjustments will be required and quarterly results may be affected.
Quarterly results may also be affected by movements of Payor members from one
Payor to another, particularly during periods of open enrollment for HMOs.
Fluctuations in FPA's quarterly operating results could result in significant
volatility in, and otherwise adversely affect, the market price of FPA Common
Stock.
 
     Possible Volatility of Stock Price. Recently, there has been significant
volatility in the market prices of securities of companies in the health care
industry, including the price of FPA Common Stock. Many factors, including
announcements of new legislative proposals or laws relating to health care
reform, the performance of, and investor expectations for, FPA, analysts'
comments, the trading volume in FPA Common Stock and general economic and market
conditions, may influence the trading price of FPA Common Stock. Accordingly,
there can be no assurance as to the price at which FPA Common Stock will trade
in the future.
 
     Dependence Upon Key Personnel; Employment Contracts. FPA depends on the
active participation of its executive officers and directors, particularly Dr.
Sol Lizerbram, Chairman of the Board, Dr. Seth Flam, President and Chief
Executive Officer and Dr. Stephen Dresnick, President of Sterling. The loss of
the services of Drs. Lizerbram, Flam or Dresnick could have a material adverse
effect upon FPA's future operations. FPA has an employment contract with each of
Drs. Lizerbram, Flam and Dresnick. FPA has not purchased key-man life insurance
on any of its key personnel.
 
     Risk of Dilution and Additional Capital Needs. FPA's expansion strategy
includes acquisitions of, and affiliations with, individual and group physician
practices as well as organizations that provide management services to such
practices. Such acquisitions or affiliations may be consummated using newly
issued shares of common stock, or securities convertible into or exercisable for
the purchase of FPA Common Stock, as consideration. The issuance of additional
shares of FPA Common Stock may have a dilutive effect on the net tangible book
value or earnings per share following such issuance.
 
                                       30
<PAGE>   35
 
     FPA's expansion strategy also requires substantial capital investments.
Capital is needed not only for the acquisition of the assets of physician
practices, but also for their effective integration, operation and expansion and
for the addition of medical equipment and technology. In the event that FPA
Common Stock does not maintain sufficient valuation, or potential acquisition
candidates are unwilling to accept FPA Common Stock as part of the consideration
for the sale of the assets of their businesses, FPA may be required to utilize
more of its cash resources. There can be no assurance that FPA will have
sufficient cash resources or will be able to obtain additional financing or
that, if available, such financing will be on terms acceptable to FPA.
Furthermore, an inability to obtain additional capital through subsequent debt
or equity financings may negatively affect FPA's existing operations and its
future growth.
 
     Shares Eligible for Future Sale. Sales of substantial amounts of FPA Common
Stock in the public market, after conversion of the Debentures, or otherwise, or
the perception that such sales could occur, may adversely affect prevailing
market prices of the FPA Common Stock. As of             , 1997,      shares of
FPA Common Stock were issued and outstanding. In addition, as of             ,
1997, FPA has granted options or warrants to purchase, or securities (excluding
the Debentures) convertible into, approximately      shares of FPA Common Stock
and 3,107,900 shares of FPA Common Stock are issuable upon conversion of the
Debentures. In addition to the registration rights to be granted to certain
stockholders of HPI in connection with the Merger covering approximately
     shares of FPA Common Stock (assuming an FPA Value of $          ) and
assuming the effectiveness of FPA's Registration Statement on Form S-3 to
register for resale 1,940,960 shares of FPA Common Stock issued in connection
with the HealthCap acquisition, approximately 600,000 shares of outstanding FPA
Common Stock are subject to registration rights agreements which obligate FPA to
register such shares. In addition, FPA has granted registration rights to
certain former AHI stockholders in the event that such stockholders are unable
to sell a specified number of shares in accordance with the provisions of Rule
144, although FPA does not believe a registration statement regarding such
shares will need to be filed. All remaining FPA shares are freely tradeable,
without restriction under the Securities Act.
 
     Anti-Takeover Effect of Certain Charter Provisions. FPA's Certificate of
Incorporation, as amended, and Bylaws 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 FPA. FPA's
Certificate of Incorporation authorizes the FPA Board without the approval of
the stockholders to issue preferred stock. 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.
There are no shares of preferred stock presently outstanding and FPA has no
present plans to issue any shares of preferred stock.
 
     Under FPA's Credit Agreement, a merger, consolidation or Acquisition (as
defined therein), other than certain Permitted Acquisitions (as defined
therein), by FPA constitutes an event of default. These provisions of FPA's
Credit Agreement could serve to impede or prevent a change of control or have a
depressive effect on the price of FPA Common Stock. Pursuant to the Merger
Agreement, FPA has agreed to use its best efforts to receive a consent from the
relevant bank on or before August 15, 1997, to avoid such event of default as a
result of the Merger.

RISKS RELATING TO THE MERGER
 
     Impact on FPA's Financial Statements. FPA expects to incur non-recurring
costs in connection with the Merger aggregating approximately $15.5 million
relating primarily to certain employee termination costs, financial advisory
fees, professional fees and restructuring costs, which costs will be expensed in
the first quarter after the Closing. See "SELECTED HISTORICAL AND PRO FORMA
INFORMATION."
 
     No Assurance of Successful Integration of Certain Operations. FPA and HPI
have entered into the Merger Agreement with the expectation that the Merger will
result in certain benefits for the combined company. Achieving the anticipated
benefits of the Merger will depend in part upon whether the integration of the
two companies' business is achieved in an efficient and effective manner. There
can be no assurance that this will occur. The combination of the two companies
will require, among other things, coordination of the companies' sales and
marketing efforts and operations. There can be no assurance that integration
will be accomplished on a timely basis, or at all. The difficulties of such
integration may be increased by the necessity of consolidating geographically
separated organizations in order to achieve economies of scale. The integration
of certain operations following the Merger will require the dedication of
management resources which may distract attention from the day-to-day business
of the combined company. In particular, the management services provided by FPA
to physicians, hospitals and Payors in the FPA Network, which include 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, will have to be extended to new
members of the FPA Network. Failure to effectively accomplish the integration of
the two companies' operations could have a material adverse effect on FPA
results of operations and financial condition.
 
     Exchange Ratio May Not Fully Reflect Changes in FPA Stock Price. The FPA
Value at the Effective Time may vary significantly from the FPA stock price as
of the date of execution of the Merger Agreement, the date hereof or the date on
which stockholders vote on the Merger due to, among other factors, changes in
the business, operations and prospects of FPA, market assessments of the
likelihood that the Merger will be consummated and the timing thereof and
general market and economic conditions. Since the actual number of shares of FPA
Common Stock issuable to HPI stockholders in the Merger depends on the FPA
Value, the fair value of the HPI Options and the issuance of HPI Common Stock in
the Roll-up Transactions, there is no guarantee as to the number of shares or
value of the FPA Common Stock that HPI stockholders will receive. Each HPI
stockholder is urged to obtain updated FPA market information. See "THE
MERGER -- Adjustments to Merger Consideration."
 
     Need for Additional Capital. Upon consummation of the Merger, FPA will be a
larger company and may therefore require additional capital in order to continue
to expand its operations. Failure to secure additional financing could have an
adverse effect on FPA's operations. There can be no assurance that FPA will be
able to obtain such additional financing, or if available it will be on terms
acceptable to FPA.
 
     Possible Loss of Business. Despite the efforts of each of FPA and HPI,
current key independent contractor physicians, employees or clients of HPI may
not continue to contract with HPI or FPA following the Merger. The loss of a
material number of independent contractor physicians, employees or clients could
adversely affect the operations of HPI and FPA. As of March 31, 1997, Oxford
represented 69% of HPI's revenue and on a combined pro forma basis would have
represented approximately 12% of FPA's revenue as of such date. The termination
of the Oxford agreement or a significant reduction in revenues from Oxford could
adversely affect the results of operations of FPA after the Merger.
 
     Rights of HPI Stockholders Following the Merger. Following the Merger,
holders of HPI Common Stock and HPI Preferred Stock will become holders of FPA
Common Stock. Certain differences exist between the rights of the HPI
stockholders under the HPI Certificate of Incorporation and Bylaws and the 1994
Securities Purchase Agreement, and the rights of FPA stockholders under the FPA
Certificate of Incorporation and Bylaws. Among other things, the differences
include a classified board of directors in the case of FPA, different procedures
for calling special meetings of stockholders, different procedures for
nomination of directors and supermajority vote requirements for certain
provisions in the case of HPI. In addition, FPA has a stockholders' rights plan
and HPI does not.

     Federal Income Tax Consequences. The Merger is intended to qualify for
federal income tax purposes as a tax-free reorganization under the Code. If for
any reason the Merger does not qualify as a reorganization, then among other
effects, the HPI stockholders may recognize gain or loss in such transaction. No
ruling from the Internal Revenue Service has been requested regarding the
federal income tax consequences of the Merger. ACCORDINGLY, ALL HPI STOCKHOLDERS
ARE URGED TO CONSULT THEIR TAX ADVISORS REGARDING ALL TAX RAMIFICATIONS OF THE
MERGER. See "THE MERGER -- Material Federal Income Tax Consequences."

                            THE HPI SPECIAL MEETING
 
     This Proxy Statement is being furnished to the stockholders of HPI in
connection with the solicitation of proxies by and on behalf of the Board of
Directors for use at the HPI Special Meeting. This Proxy Statement/Prospectus
and the related form of proxy for HPI are first being mailed to HPI stockholders
on or about           , 1997.
 
DATE, TIME AND PLACE
 
     The HPI Special Meeting will be held on             , 1997 at 10:00 a.m.,
local time, at HPI's offices located at 800 Connecticut Ave., Norwalk,
Connecticut.
 
PURPOSE OF THE HPI SPECIAL MEETING
 
     At the HPI Special Meeting, the stockholders of HPI will be asked to
consider and vote upon the adoption and approval of the Merger Agreement under
which, among other things, Merger Sub would be merged into HPI, with HPI
surviving the Merger as a wholly owned subsidiary of FPA. Pursuant to the
Merger, each outstanding share of HPI Common Stock will be exchanged for the
right to receive a number of shares of FPA Common Stock equal to the Exchange
Ratio. The Exchange Ratio will vary based on the FPA Value, the Outstanding HPI
Stock and the number of FPA Option Shares. Based upon           shares of
Outstanding HPI Stock,           FPA Option Shares and assuming an FPA Value
equal to $          , which was the closing price of FPA Common Stock on
            , 1997, the Exchange Ratio would be           . Based upon such
assumptions, HPI's stockholders and option holders would be issued an aggregate
of approximately           shares of FPA Common Stock, representing
approximately   % of the total issued and outstanding shares of FPA Common Stock
after the Merger. See "THE MERGER -- Adjustments to Merger Consideration."
 
     The HPI Board has unanimously approved the Merger Agreement and recommends
a vote FOR approval and adoption of the Merger Agreement.
 
     At the HPI Special Meeting, the stockholders of HPI will also be asked to
consider and vote upon a proposal to approve the Payments to Charles G. Berg,
the President and Chief Executive Officer of HPI. The HPI Board has approved the
Payments (with Mr. Berg abstaining) and recommends a vote FOR approval of the
Payments. See "THE PAYMENTS."
 
REVOCATION OF PROXIES
 
     Except for those who have executed irrevocable proxies, any holder of HPI
Voting Securities has the unconditional right to revoke his or her proxy at any
time prior to the voting thereof at the HPI Special Meeting by (i) filing a
written revocation with the Secretary of HPI prior to the voting of such proxy,
(ii) giving a duly executed proxy bearing a later date or (iii) attending the
HPI Special Meeting and voting in person. Attendance by a stockholder at the HPI
Special Meeting will not itself revoke his or her proxy.
 
QUORUM
 
     The presence, in person or by proxy, of the holders of a majority of the
HPI Voting Securities (with the HPI Preferred Stock weighted on an as-converted
basis) at the HPI Special Meeting is necessary to constitute a quorum at the HPI
Special Meeting. Abstentions and non-votes will be included in determining the
presence of a quorum.
 
VOTE REQUIRED
 
     For purposes of voting at the HPI Special Meeting, the shares of HPI
Preferred Stock will be weighted on an as-converted basis. The affirmative vote
of the holders of at least 60% of the HPI Voting Securities, voting together as
a class, either in person or by proxy, at the HPI Special Meeting is required to
approve the Merger Agreement. The affirmative vote of the holders of a majority
of the HPI Voting Securities present,
 
                                       34
<PAGE>   39
 
either in person or by proxy, at the HPI Special Meeting is required to approve
the possible adjournment or postponement of the HPI Special Meeting.
 
     The affirmative vote of the holders of at least 75% of the HPI Voting
Securities, voting together as a class, either in person or by proxy, excluding
shares owned by Mr. Berg or certain of his family members, is required to
approve the Payments. Approval of the Payments is not a condition to the Merger.
 
RECORD DATE; STOCK ENTITLED TO VOTE
 
     The HPI Board has established             , 1997 (the "Record Date") as the
date to determine those record holders of HPI Voting Securities entitled to
notice of and to vote at the HPI Special Meeting. On that date, there were
1,673,500 shares of HPI Common Stock outstanding, 25,000 shares of Series A
Convertible Preferred Stock outstanding and 25,000 shares of Series B
Convertible Preferred Stock outstanding. Each share of HPI Common Stock is
entitled to one vote, each share of Series A Convertible Preferred stock is
entitled to 132 votes and each share of Series B Convertible Preferred stock is
entitled to 188 votes with respect to all matters to be voted upon at the HPI
Special Meeting.
 
     In the event the Merger is not approved and adopted by the stockholders of
HPI, the Merger Agreement may be terminated in accordance with its terms. See
"THE MERGER AGREEMENT -- Termination."
 
VOTING OF PROXIES
 
     At the HPI Special Meeting, abstentions and non-votes will have the effect
of a vote against adoption of the Merger Agreement and against approval of the
Payments. Because abstentions are treated as shares present and entitled to vote
at the HPI Special Meeting, they will have the effect of a vote against approval
of the possible adjournment or postponement of the HPI Special Meeting.
Non-votes are not allowed to vote at the HPI Special Meeting and will have no
effect on the outcome of a proposal to approve the possible adjournment or
postponement of the HPI Special Meeting.
 
     If a holder of HPI Voting Securities does not return a signed proxy card
and does not attend the meeting and vote in person, his or her shares will not
be voted. Shares not voted will have the effect of a vote against the Merger
Agreement and against the Payments at the HPI Special Meeting.
 
SOLICITATION OF PROXIES
 
     Solicitation of proxies for use at the HPI Special Meeting may be made in
person or by mail, telephone, telecopy or telegram. HPI will conduct the
solicitation of proxies for the HPI Special Meeting and will bear the cost of
the solicitation of such proxies from its stockholders. In addition to
solicitation by mail, the directors, officers and employees of HPI may solicit
proxies from HPI stockholders by telephone or telegram or in person. Such
directors, officers and employees will not be compensated for such solicitation.
 
STOCKHOLDERS' RIGHT OF APPRAISAL
 
     Holders of HPI Voting Securities as of the Record Date have the right to
demand judicial appraisal of, and obtain a cash payment for, the "fair value" of
their shares (exclusive of any element of value arising from the accomplishment
or expectation of the Merger) pursuant to Section 262 of the Delaware Act. In
order to exercise such rights, such holders of HPI Voting Securities must not
vote in favor of the Merger and must comply with the procedural requirements of
Section 262 of the Delaware Act. The full text of Section 262 of the Delaware
Act is attached hereto as Appendix C, and any holder of HPI Voting Securities
desiring to exercise dissenters' rights of appraisal in connection with the
Merger should consult with legal counsel prior to taking any action in order to
ensure that the stockholder complies with the applicable statutory provision.
Failure to take any of the steps required under Section 262 of the Delaware Act
on a timely basis may result in the loss of appraisal rights. See "THE
MERGER -- Rights of Dissenting Stockholders" and Appendix C hereto.

SECURITY OWNERSHIP OF CERTAIN HPI OWNERS AND MANAGEMENT
 
     As of the Record Date, directors and executive officers of HPI named in the
Summary Compensation Table had the right to vote approximately 10.60% of the HPI
Voting Securities (treating the HPI Preferred Stock on an as-converted basis).
As provided by the terms of the relevant Certificate of Designations, each share
of HPI Series A Convertible Preferred Stock is convertible into and votes the
equivalent of approximately 132 shares of HPI Common Stock and each share of HPI
Series B Convertible Preferred Stock is convertible into and votes the
equivalent of approximately 188 shares of HPI Common Stock. WellPoint owns all
25,000 outstanding shares of the Series A Convertible Preferred Stock,
representing approximately 34.11% of the HPI Voting Securities. Oxford owns all
25,000 outstanding shares of Series B Convertible Preferred Stock, representing
48.59% of the HPI Voting Securities. On July 1, 1997, Oxford and WellPoint
entered into a stockholders agreement and related proxy in which they each
granted an irrevocable proxy to FPA to vote their HPI securities in favor of the
Merger Agreement and the transactions contemplated thereby and to convert their
shares of HPI Preferred Stock into shares of HPI Common Stock prior to the
Effective Time. See "SECURITY OWNERSHIP OF CERTAIN HPI BENEFICIAL OWNERS AND
MANAGEMENT."

                                   THE MERGER
 
EFFECTS OF THE MERGER
 
     The Merger Agreement provides that the Merger will be consummated promptly
following approval by the holders of HPI Voting Securities and the satisfaction
or waiver of all other conditions to consummation of the Merger. At the
Effective Time, Merger Sub will be merged with and into HPI, and HPI, as the
Surviving Corporation, will be a wholly owned subsidiary of FPA. Stockholders of
HPI will become stockholders of FPA and their rights will be governed by the
Certificate of Incorporation and Bylaws of FPA.
 
MERGER CONSIDERATION
 
     Pursuant to the Merger Agreement, at the Effective Time, Merger Sub will
merge with and into HPI and each share of HPI Common Stock issued and
outstanding immediately prior to the Effective Time (other than shares of HPI
Common Stock owned by HPI as treasury stock and shares of HPI Common Stock owned
by FPA, Merger Sub or any wholly owned subsidiary of FPA or HPI to be cancelled
in accordance with the Merger Agreement) shall be converted into the right to
receive a number of shares of FPA Common Stock equal to the Exchange Ratio. The
holders of HPI Preferred Stock have agreed to convert their shares of HPI
Preferred Stock to HPI Common Stock prior to the Effective Time.
 
     The Exchange Ratio depends on the relationship among (i) the total issued
and outstanding shares of HPI Common Stock (the "Outstanding HPI Stock")
immediately prior to the Effective Time (including the total number of shares of
HPI Common Stock issued or issuable pursuant to the Roll-up Transactions and the
conversion of all of the shares of HPI Preferred Stock), (ii) the fair value of
options to purchase HPI Common Stock (the "HPI Options") which will be converted
in the Merger into fully paid shares of FPA Common Stock (the "FPA Option
Shares"), (iii) the presumed transaction value of $115 million and (iv) the FPA
Value. The FPA Value will be the average of the closing prices of FPA Common
Stock on Nasdaq for the ten consecutive trading days ending on the date that is
two trading days prior to the Closing Date. The "Adjusted FPA Value" will equal
the FPA Value, except that if the FPA Value is less than $18, the Adjusted FPA
Value will be $18 and if the FPA Value is greater than $22, the Adjusted FPA
Value will be $22. Consequently, the Adjusted FPA Value may differ from the
actual market price of FPA Common Stock reported by Nasdaq on the date of the
HPI Special Meeting, the Closing Date or the date the HPI stockholders actually
receive their shares of FPA Common Stock after the Merger is completed. See "THE
MERGER AGREEMENT -- Roll-up Transactions" and "-- Treatment of Stock Options."
 
     The Exchange Ratio can be represented by the following formula:
 
<TABLE>
<S>               <C>
  Exchange Ratio =    ($115 Million (divided by) Adjusted FPA Value) - 
                                      FPA Option Shares
                  ---------------------------------------------------------
                                    Outstanding HPI Stock
</TABLE>
 
     On             , 1997 the closing price of FPA Common Stock was
$          . Assuming an FPA Value equal to such price,        shares of
Outstanding HPI Stock (including conversion of all outstanding shares of HPI
Preferred Stock and the        shares of HPI Common Stock to be issued in
connection with the completion of the Roll-up Transactions) and           FPA
Option Shares, the Exchange Ratio would have been           . Based upon these
assumptions, HPI's stockholders and option holders would be issued approximately
          shares of FPA Common Stock, representing approximately   % of the
total issued and outstanding shares of FPA after the Merger. The actual market
price of the FPA Common Stock may vary, which may cause a change in the Exchange
Ratio and the aggregate Merger Consideration. Each HPI stockholder is urged to
obtain updated FPA market information.
 
ADJUSTMENTS TO MERGER CONSIDERATION
 
     The consideration to be issued to each HPI stockholder in the Merger will
be that number of shares of FPA Common Stock which is determined by multiplying
the Exchange Ratio by the number of shares of HPI Common Stock held by such HPI
stockholder on the Closing Date (the "Merger Consideration"). As described in
the previous section, the Exchange Ratio will vary based on the FPA Value. The
FPA Value may differ from the actual market price of FPA Common Stock reported
by Nasdaq on the date of the HPI Special
 
                                       37
<PAGE>   42
 
Meeting, the Closing Date or the date the HPI stockholders actually receive
their shares of FPA Common Stock after the Merger is completed. The Merger
Agreement may be terminated by HPI if the FPA Value is less than $15.65. If,
prior to the Effective Time, the announcement of a transaction by FPA requires
the amendment of the Registration Statement of which this Proxy
Statement/Prospectus is a part, and, as a result of such amendment, the Closing
occurs later than September 29, 1997 and the FPA Value is below $18.00, for
purposes of determining the Exchange Ratio, there will be no adjustment to the
FPA Value. Except as a result of events described in the previous sentence, in
no event will the number of shares of FPA Common Stock issuable in the Merger
exceed 6,388,889. Since the actual number of shares of FPA Common Stock issuable
to HPI stockholders in the Merger depends on the FPA Value, the number of
Outstanding HPI Common Stock and the number of FPA Option Shares, there is no
guarantee as to the number of shares or value of the FPA Common Stock that HPI
stockholders will receive.
 
CONVERSION OF SHARES; PROCEDURES FOR EXCHANGE OF CERTIFICATES; FRACTIONAL SHARES
 
     The conversion of HPI Common Stock into the right to receive FPA Common
Stock will occur automatically at the Effective Time.
 
     As soon as practicable after the Effective Time, American Stock Transfer &
Trust Company or another bank or trust company designated by FPA and reasonably
acceptable to HPI, in its capacity as exchange agent (the "Exchange Agent"),
will send a transmittal form to each HPI stockholder of record. The transmittal
form will contain instructions with respect to the surrender of certificates
representing HPI Common Stock to be exchanged for FPA Common Stock.
 
     HPI STOCKHOLDERS SHOULD NOT FORWARD HPI STOCK CERTIFICATES TO THE EXCHANGE
AGENT UNTIL THEY HAVE RECEIVED TRANSMITTAL FORMS. HPI STOCKHOLDERS SHOULD NOT
RETURN STOCK CERTIFICATES WITH THE ENCLOSED PROXY.
 
     Until the certificates representing HPI Common Stock are surrendered for
exchange after the consummation of the Merger, holders of such certificates will
not be paid dividends on the FPA Common Stock into which such shares have been
exchanged. When such certificates are surrendered, any unpaid dividends will be
paid without interest. For all other purposes, however, each certificate which
represents shares of HPI Common Stock at the Effective Time will be deemed to
evidence ownership of the shares of FPA Common Stock into which those shares are
entitled to be exchanged by virtue of the Merger.
 
     All shares of FPA Common Stock issued upon the exchange of shares of HPI
Common Stock shall be deemed to have been issued in full satisfaction of all
rights pertaining to such shares of HPI Common Stock.
 
     No fractional shares of FPA Common Stock will be issued to any HPI
stockholder upon consummation of the Merger. For each fractional share that
would otherwise be issued, the Exchange Agent will pay by check an amount equal
to such fraction multiplied by the FPA Value.
 
NASDAQ LISTING
 
     It is a condition to the Merger that the shares of FPA Common Stock to be
issued in the Merger be authorized for inclusion on Nasdaq.
 
BACKGROUND OF THE MERGER
 
     FPA's strategy for enhancing long-term value for its stockholders has been
to increase the number of enrollees and primary care physicians in the FPA
Network and to negotiate favorable contracts with Payors to provide physician
and related health care services to enrollees who select FPA primary care
physicians. The FPA Board believes that by doing so, FPA can enhance revenues
and earnings. FPA has grown significantly as a result of several recent
acquisitions. The FPA Board periodically reviews various strategic opportunities
to enhance profitability and increase stockholder value. In this regard, the FPA
Board continually evaluates the acquisition of other entities and medical
practices and has considered longer term acquisition opportunities
 
                                       38
<PAGE>   43
 
and other strategic alternatives. The FPA Board determined that the Merger would
enhance FPA by extending its geographic coverage, especially to the New York
metropolitan area, and by the strategic relationships with Oxford and WellPoint
Parent being developed as a result of the Merger and the transactions
contemplated thereby.
 
     HPI raised $50.0 million under the 1994 Securities Purchase Agreement,
which proceeds were utilized to fund HPI's business plan. In July 1996, HPI
began exploring an initial public offering of its common stock to raise
additional capital to fund its acquisition and growth plans. In November 1996,
HPI decided not to pursue an initial public offering of its stock due to adverse
market conditions in the PPM sector and retained Smith Barney to assist HPI in
exploring other strategic alternatives. At the direction of HPI, Smith Barney
initially contacted five potential buyers, four publicly traded strategic buyers
and one financial sponsor as a potential partner. Each of the parties contacted
entered into a confidentiality agreement and received a confidential memorandum
relating to HPI. Three publicly traded strategic buyers submitted preliminary
indications of interest and conducted due diligence on HPI. After completing due
diligence, two parties submitted offers and senior management of HPI and its
legal and financial advisors negotiated with both parties to reach mutually
acceptable terms for a transaction. During this period, HPI's senior management
held numerous discussions about potential transactions with representatives of
HPI's institutional investors, members of HPI's Board and HPI's legal and
financial advisors.
 
     Upon review of the two negotiated transactions, HPI's management determined
that HPI's stockholders would receive greater value from a transaction with FPA
due to its strategic fit, its complementary business plan and FPA's market
capitalization and liquidity. On June 27, 1997, the HPI Board met to consider
approval of the Merger Agreement and the transactions contemplated thereby. At
this meeting, Smith Barney rendered an oral opinion, subsequently confirmed by
delivery of a written opinion dated July 1, 1997, the date of execution of the
Merger Agreement, to the effect that, as of such date and based upon and subject
to certain matters described in its written opinion, the Merger Consideration
was fair from a financial point of view to the holders of HPI Common Stock. See
"THE MERGER -- Opinion of HPI's Financial Advisor." The HPI Board unanimously
concluded in its June 27, 1997 meeting that the transaction was fair and in the
best interests of HPI's stockholders and unanimously approved the transaction.
Negotiations were completed and the Merger Agreement was signed on July 1, 1997.
 
RECOMMENDATION OF THE HPI BOARD OF DIRECTORS AND REASONS FOR THE MERGER
 
     On June 27, 1997, the HPI Board unanimously determined that the terms of
the Merger Agreement and the transactions contemplated thereby are fair to, and
in the best interest of, HPI and its stockholders. In reaching its decision to
recommend and approve the Merger Agreement, the HPI Board consulted with
management, as well as its financial, accounting and legal advisors, and
considered the following factors to be material and favorable in its
determination to unanimously approve the Merger Agreement and the transactions
contemplated thereby:
 
          (i) the attractive opportunity to strengthen HPI's competitive
     position and enhance its profile among physicians and Payors;
 
          (ii) the increasing competitive pressures within the managed care
     sector of the health care industry, including the trend toward
     consolidation among Payors, providers and physician practice management
     companies;
 
          (iii) the belief that there were strategic benefits which could be
     attained by combining FPA's and HPI's operations including, but not limited
     to, forming one of the largest physician practice management companies in
     the nation and thereby providing the combined company with the opportunity
     to operate more effectively and profitably in this dynamic and increasingly
     competitive environment as a result of the size, geographic scope and
     expertise of the combined company;
 
          (iv) the belief that certain synergies could be attained by spreading
     the costs of infrastructure over a greater membership base and by combining
     operations and development activities in overlapping
 
                                       39
<PAGE>   44
 
     markets, thereby reducing general and administrative expenses and
     contributing to the ability of the combined company to compete effectively
     in the future;
 
          (v) the opinion of Smith Barney rendered to the HPI Board on June 27,
     1997 (subsequently confirmed by delivery of a written opinion dated July 1,
     1997, the date of execution of the Merger Agreement), to the effect that,
     as of the date of such opinion and based upon and subject to certain
     matters stated therein, the Merger Consideration was fair, from a financial
     point of view, to the holders of HPI Common Stock (See "THE
     MERGER -- Opinion of HPI's Financial Advisor");
 
          (vi) the terms and conditions of the Merger Agreement and related
     agreements and the likelihood that the conditions to the Merger would be
     satisfied;
 
          (vii) the willingness of management to support the Merger; and
 
          (viii) the liquidity desire of the HPI stockholders and the trading
     volume of FPA Common Stock and its effect on such liquidity.
 
     In addition to the foregoing factors, the HPI Board consulted with
management, as well as its financial, accounting and legal advisors, and
considered the following factors to be material and adverse in its determination
to unanimously approve the Merger Agreement and the transactions contemplated
thereby:
 
          (i) the ability of FPA to integrate successfully HPI's operations
     following consummation of the Merger, particularly in light of FPA's recent
     acquisitions of Sterling, Foundation, AHI and HealthCap;
 
          (ii) the ability of FPA to sustain its growth strategy; and
 
          (iii) the amount of FPA's indebtedness in relation to its total
     stockholders' equity.
 
The HPI Board reviewed these adverse factors in their totality, without focusing
on any one individual factor, and concluded that on balance, despite such
factors, HPI would be better positioned to face those underlying risks as well
as accomplish its business plan if it combined with FPA. The HPI Board also
believes that FPA is capable of addressing the issues raised by the integration
of HPI operations following consummation of the Merger.
 
     The foregoing discussion of the information and factors considered is not
intended to be exhaustive, but it does include the material factors, favorable,
neutral and adverse, considered by the HPI Board in the evaluation of the
Merger. The HPI Board reviewed the foregoing factors in their totality, without
focusing on any one individual factor. Without giving relative weights to the
respective factors, favorable, neutral and adverse, and without drawing a
correlation among the factors, the HPI Board determined that the factors adverse
to the Merger were not sufficient to negate the incentives for pursuing and
potential benefits of, the Merger. The HPI Board unanimously determined that the
Merger was fair to and in the best interest of the HPI stockholders and that HPI
should proceed with the Merger.
 
     ACCORDINGLY, THE HPI BOARD UNANIMOUSLY RECOMMENDS THAT THE STOCKHOLDERS OF
HPI VOTE "FOR" APPROVAL OF THE PROPOSAL TO ADOPT THE MERGER AGREEMENT.
STOCKHOLDERS SHOULD BE AWARE THAT CERTAIN MEMBERS OF THE HPI BOARD AND
MANAGEMENT HAVE CERTAIN INTERESTS IN THE MERGER THAT MAY CONFLICT WITH AND ARE
IN ADDITION TO THOSE OF OTHER HPI STOCKHOLDERS. SEE "THE MERGER -- INTERESTS OF
CERTAIN PERSONS IN THE MERGER."
 
OPINION OF HPI'S FINANCIAL ADVISOR
 
     Smith Barney was retained by HPI to act as its financial advisor in
connection with the proposed Merger. In connection with such engagement, HPI
requested that Smith Barney evaluate the fairness, from a financial point of
view, to the holders of HPI Common Stock of the consideration to be received by
such holders in the Merger. On June 27, 1997, at a meeting of the Board of
Directors of HPI held to evaluate the proposed Merger, Smith Barney delivered to
the Board of Directors of HPI an oral opinion (which opinion was subsequently
confirmed by delivery of a written opinion dated July 1, 1997, the date of
execution of the
 
                                       40
<PAGE>   45
 
Merger Agreement) to the effect that, as of the date of such opinion and based
upon and subject to certain matters stated therein, the Merger Consideration was
fair, from a financial point of view, to the holders of HPI Common Stock.
 
     In arriving at its opinion, Smith Barney reviewed the Merger Agreement and
held discussions with certain senior officers, directors and other
representatives and advisors of HPI and certain senior officers and other
representatives of FPA concerning the business, operations and prospects of HPI
and FPA. Smith Barney examined certain business and financial information
relating to HPI and certain publicly available business and financial
information relating to FPA as well as certain financial forecasts and other
information and data for HPI and FPA which were provided to or otherwise
discussed with Smith Barney by the respective managements of HPI and FPA,
including information relating to certain strategic implications and operations
benefits anticipated to result from the Merger. Smith Barney reviewed the
financial terms of the Merger as set forth in the Merger Agreement in relation
to, among other things, current and historical market prices and trading volumes
of FPA Common Stock; the historical and projected earnings and other operating
data of HPI and FPA; and the capitalization and financial condition of HPI and
FPA. Smith Barney considered, to the extent publicly available, the financial
terms of certain other similar transactions recently effected which Smith Barney
considered relevant in evaluating the Merger and analyzed certain financial,
stock market and other publicly available information relating to the businesses
of other companies whose operations Smith Barney considered relevant in
evaluating those of HPI and FPA. Smith Barney also evaluated the potential pro
forma financial impact of the Merger on FPA. In connection with its engagement,
Smith Barney was requested to approach on a limited basis, and held discussions
with, certain third parties to solicit indications of interest in a possible
acquisition of HPI as described in "THE MERGER -- Background of the Merger." In
addition to the foregoing, Smith Barney conducted such other analyses and
examinations and considered such other financial, economic and market criteria
as Smith Barney deemed appropriate in arriving at its opinion. Smith Barney
noted that its opinion was necessarily based upon information available, and
financial, stock market and other conditions and circumstances existing and
disclosed, to Smith Barney as of the date of its opinion.
 
     In rendering its opinion, Smith Barney assumed and relied, without
independent verification, upon the accuracy and completeness of all financial
and other information and data publicly available or furnished to or otherwise
reviewed by or discussed with Smith Barney. With respect to financial forecasts
and other information and data provided to or otherwise reviewed by or discussed
with Smith Barney, the managements of HPI and FPA advised Smith Barney that such
forecasts and other information and data were reasonably prepared on bases
reflecting the currently available estimates and judgments of the managements of
HPI and FPA as to the future financial performance of HPI and FPA and the
strategic implications and operational benefits anticipated to result from the
Merger. Smith Barney assumed, with the consent of the Board of Directors of HPI,
that the Merger will be treated as a pooling of interests in accordance with
generally accepted accounting principles and as a tax-free reorganization for
federal income tax purposes. Smith Barney also assumed, with the consent of the
Board of Directors of HPI, and took into account to the extent relevant to its
analysis, that prior to the consummation of the Merger all outstanding shares of
the Series A Convertible Preferred Stock and Series B Convertible Preferred
Stock of HPI and outstanding minority interests in subsidiaries of HPI will be
converted into shares of HPI Common Stock. Smith Barney did not express any
opinion as to what the value of the FPA Common Stock actually will be when
issued to HPI stockholders pursuant to the Merger or the price at which the FPA
Common Stock will trade subsequent to the Merger. Smith Barney did not make and
was not provided with an independent evaluation or appraisal of the assets or
liabilities (contingent or otherwise) of HPI or FPA nor did Smith Barney make
any physical inspection of the properties or assets of HPI or FPA. Although
Smith Barney evaluated the Merger Consideration from a financial point of view,
Smith Barney was not asked to and did not recommend the specific consideration
payable in the Merger, which was determined through negotiation between HPI and
FPA. No other limitations were imposed by HPI on Smith Barney with respect to
the investigations made or procedures followed by Smith Barney in rendering its
opinion.

APPENDIX B AND IS INCORPORATED HEREIN BY REFERENCE. HOLDERS OF HPI VOTING
SECURITIES ARE URGED TO READ THIS OPINION CAREFULLY IN ITS ENTIRETY. THE OPINION
OF SMITH BARNEY IS DIRECTED TO THE BOARD OF DIRECTORS OF HPI AND RELATES ONLY TO
THE FAIRNESS OF THE MERGER CONSIDERATION FROM A FINANCIAL POINT OF VIEW, DOES
NOT ADDRESS ANY OTHER ASPECT OF THE MERGER OR RELATED TRANSACTIONS AND DOES NOT
CONSTITUTE A RECOMMENDATION TO ANY STOCKHOLDER AS TO HOW SUCH STOCKHOLDER SHOULD
VOTE AT THE HPI SPECIAL MEETING. THE SUMMARY OF THE OPINION OF SMITH BARNEY SET
FORTH IN THIS PROXY STATEMENT/PROSPECTUS IS QUALIFIED IN ITS ENTIRETY BY
REFERENCE TO THE FULL TEXT OF SUCH OPINION.
 
     Smith Barney's opinion was only one of many factors considered by the Board
of Directors of HPI in its evaluation of the Merger and should not be viewed as
determinative of the views of the Board of Directors or management of HPI with
respect to the Merger Consideration or the proposed Merger.
 
     Pursuant to the terms of Smith Barney's engagement, HPI has agreed to pay
Smith Barney for its services in connection with the Merger an aggregate
financial advisory fee equal to 1.25% of the total consideration (including
liabilities assumed) payable in connection with the Merger. HPI has also agreed
to reimburse Smith Barney for reasonable travel and other out-of-pocket expenses
incurred by Smith Barney in performing its services, including the reasonable
fees and expenses of its legal counsel, and to indemnify Smith Barney and
related persons against certain liabilities, including liabilities under the
federal securities laws, arising out of Smith Barney's engagement.
 
     Smith Barney has advised HPI that, in the ordinary course of business,
Smith Barney and its affiliates may actively trade or hold the securities of FPA
for their own account or for the account of customers and, accordingly, may at
any time hold a long or short position in such securities. Smith Barney has in
the past provided investment banking services to FPA unrelated to the proposed
Merger, for which services Smith Barney has received compensation. In addition,
Smith Barney and its affiliates (including Travelers Group, Inc. and its
affiliates) may maintain relationships with HPI and FPA.
 
     Smith Barney is an internationally recognized investment banking firm and
was selected by HPI based on Smith Barney's experience and expertise. Smith
Barney regularly engages in the valuation of businesses and their securities in
connection with mergers and acquisitions, negotiated underwriting, competitive
bids, secondary distributions of listed and unlisted securities, private
placements and valuations for estate, corporate and other purposes.
 
EFFECTIVE TIME OF THE MERGER
 
     Upon the terms and conditions of the Merger Agreement, Merger Sub will be
merged with and into HPI at the Effective Time. The Merger will become effective
when the Certificate of Merger is filed with the Secretary of State of Delaware
or at such time thereafter as is provided in the Certificate of Merger. The
filing of the Certificate of Merger will be made as soon as practicable on or
after the Closing.
 
     The Closing shall take place on the Closing Date, at the offices of
Pillsbury Madison & Sutro LLP, 101 West Broadway, Suite 1800, San Diego,
California, unless another date or place is agreed to by the parties. See "THE
MERGER AGREEMENT -- Conditions to the Merger."
 
INTERESTS OF CERTAIN PERSONS IN THE MERGER
 
     Certain members of management as well as directors and officers of HPI have
certain interests in the Merger that are in addition to their interests as
stockholders in HPI generally. The HPI Board of Directors was aware of these
interests and considered them, among other matters, in approving the Merger
Agreement and in formulating its recommendation to the stockholders of HPI that
they approve the Merger Agreement and the transactions contemplated therein.
 
     Berg Employment Agreements. Mr. Berg is subject to an existing employment
agreement dated September 1, 1993 with HPI (the "HPI Employment Agreement").
Under the HPI Employment Agreement, Mr. Berg is entitled to receive certain
payments and benefits (the "Payments") following the termination of such
agreement, if the termination resulted from a material alteration in Mr. Berg's
duties. The HPI Board has determined that the Merger will cause such a material
alteration. Therefore, at the Effective
 
                                       42
<PAGE>   47
 
Time, the HPI Employment Agreement will be terminated and Mr. Berg will be
entitled to receive the Payments. As a result of such termination, Mr. Berg will
receive from HPI a cash payment equal to $350,000 (consisting of severance and
related benefits of $250,000 and $100,000 in accrued bonus) and all of his
outstanding unvested HPI Options will vest. See "THE PAYMENTS." The aggregate
number of shares of HPI Common Stock underlying the unvested portion of Mr.
Berg's HPI Options is 239,150, of which 69,300 are scheduled to vest in 1998,
69,300 in 1999, 69,300 in 2000 and 31,250 in 2001. The exercise prices for such
options range from $.001 per share to $4.25 per share.
 
     Upon consummation of the Merger, Mr. Berg will enter into a new employment
agreement with FPA (the "FPA Employment Agreement"). The FPA Employment
Agreement will have a term of three years and provide a base salary of $240,000
per year (which may be increased but not decreased at annual reviews) and an
annual performance bonus opportunity of up to 50% of his then current base
salary. In addition, Mr. Berg will receive a payment at the Effective Time of
$300,000 (in consideration for entering into the FPA Employment Agreement). Mr.
Berg is entitled to a payment of $365,000 as consideration for a covenant not to
compete contained in the FPA Employment Agreement. Such amount will be paid upon
expiration or termination of the FPA Employment Agreement and the commencement
of the non-compete period. Mr. Berg will be granted a nonqualified option to
purchase 75,000 shares of FPA Common Stock with a per share exercise price equal
to the fair market value of a share of FPA Common Stock on the date of grant.
The term of the option will be ten years from the date of grant unless
terminated earlier pursuant to the terms of the stock option agreement. Subject
to certain terms and conditions, options to purchase up to 30,000 shares of FPA
Common Stock are scheduled to vest on each of the first two anniversaries of the
date of grant (5,000 will vest automatically each year and up to 25,000 may vest
each year if certain performance criteria are satisfied) and options to purchase
5,000 shares of FPA Common Stock are scheduled to vest (automatically) on each
of the next three anniversaries of such date. Pursuant to the FPA Employment
Agreement, following a termination of Mr. Berg's employment for "Cause" (as
defined in the FPA Employment Agreement) or if Mr. Berg terminates his
employment unrelated to a "Good Reason Event" (as defined in the FPA Employment
Agreement) or if Mr. Berg terminates his employment following a Good Reason
Event, Mr. Berg is entitled to his then effective base salary and benefits
through such termination date. If Mr. Berg is terminated without Cause or if he
terminates his employment in conjunction with a Good Reason Event, then (i) Mr.
Berg will be entitled to his then effective base salary and benefits through the
date of termination and for a period of eighteen months thereafter and (ii) all
of Mr. Berg's outstanding options will vest and remain outstanding until the
expiration of their original terms.
 
     Other Employment Agreements. Pursuant to the Merger Agreement and except as
described with respect to Mr. Berg, all of the existing HPI employment
agreements shall remain in full force and effect following the Effective Time.
Messrs. Phillips and Conlin have existing employment agreements which, unless
renewed, are scheduled to expire on December 31, 1998 and May 31, 1999,
respectively. The employment agreements provide for base salaries for Messrs.
Phillips and Conlin of $165,000 and $156,000 respectively and an annual bonus
opportunity of up to fifty percent of their then current base salary. The
agreements contain severance provisions which provide for payments of base
salary and benefits for a period of twelve months and nine months, respectively,
following a termination without Cause (as defined in the agreements). In
addition, HPI has committed to pay to each of Messrs. Phillips and Conlin
amounts equal to $50,000 and $25,000, respectively, as of the Effective Time.
 
     Treatment of Stock Options. Each of Messrs. Berg, Phillips and Conlin has
executed a Stock Option Acknowledgment Agreement covering all of his respective
outstanding HPI Options which provides that each option holder has agreed to the
treatment of his HPI Options as set forth in the Merger Agreement and further
described below. Pursuant to the Merger Agreement, such HPI Options, whether or
not vested, will be canceled at the Effective Time in exchange for a number of
shares of fully paid FPA Common Stock, decreased to the nearest whole share,
equal to the quotient which results when the "Fair Market Value" of such HPI
Options at the Effective Time is divided by the FPA Value. The Fair Market Value
of the HPI Options will be determined by an investment banking firm, selected by
HPI and acceptable to FPA, by applying a variation of the Black-Scholes option
pricing model. See "THE MERGER AGREE-
 
                                       43

of HPI which will be converted into FPA Common Stock are shown in the following

(1) These numbers of shares were determined as of June 30, 1997, except as
    described in footnote 4.
 
(2) These numbers of shares were determined as of June 30, 1997, except as
    described in footnote 4.
 
(3) The estimated number of shares of FPA Common Stock to be issued is based on
    an estimate of the Fair Market Value of the HPI Options and an FPA Value of
    $      . A description of how the Fair Market Value of the HPI Options is
    calculated is described above. The actual Fair Market Value of the HPI
    Options will most likely differ from the estimate based on these
    calculations, and the number of shares of FPA Common Stock issuable in
    exchange for such options will depend on the actual FPA Value.
 
(4) Mr. Berg's HPI Options are considered vested for purposes of this table
    because such options will accelerate and become fully exercisable at the
    Effective Time as a result of the termination of the HPI Employment
    Agreement.
 
(5) The September 26, 1995 option grant to Mr. Phillips was made by a subsidiary
    of HPI to purchase shares in such subsidiary. These options are subject to
    the Roll-up Transactions. For comparative purposes, this table reflects an
    estimated number of HPI Options to be issued to Mr. Phillips in the Roll-up
    Transactions and an estimated exercise price.
 
     Management Retention Program. Pursuant to an agreement reached between HPI
and FPA, FPA shall cause the Surviving Corporation to make payments to certain
key employees of the Surviving Corporation based on their continued employment
and performance during the period from the Effective Time through the first
anniversary of the Effective Time. In order to be entitled to the payment, the
employee must be employed by the Surviving Corporation, a subsidiary thereof or
FPA at the time of the first anniversary of the Effective Time, unless such
employment is earlier terminated at the request of the Surviving Corporation, a
subsidiary thereof or FPA. Also, HPI and FPA have agreed that if any of the
aforementioned key employees who do not have employment contracts are terminated
without cause at any time prior to the first anniversary of the Effective Time,
such employee will be entitled to receive six months severance and be provided
with thirty days notice of termination. Under this program, Messrs. Phillips and
Conlin are entitled to receive payments on the first anniversary of the
Effective Time in amounts equal to $90,000 and $80,000, respectively. No payment
shall be made to Mr. Berg under this program.
 
     Equity Incentive Plan. FPA has agreed to make available a pool of options
to purchase FPA Common Stock to key employees of HPI. Option grants will be
determined after the Closing and will be consistent in amount to those received
by other FPA employees with similar responsibilities. Mr. Berg will recommend
allocations of the pool among HPI key employees which will be approved in the
same manner as other FPA option grants.
 
     Registration Rights Agreement. In the Merger Agreement, FPA has agreed to
enter into a registration rights agreement (the "Registration Rights Agreement")
with Oxford, WellPoint and Messrs. Berg, Phillips and Conlin and Stephen F.
Wiggins (collectively, the "Selling Stockholders"), pursuant to which FPA will
file a registration statement with the Commission as soon as practicable after
the Closing Date covering the
 
                                       44
<PAGE>   49
 
shares of FPA Common Stock received in the Merger by the Selling Stockholders
and will use its reasonable efforts to cause such registration statement to be
declared effective on or prior to 90 days after the Closing Date (but no earlier
than 60 days following the Closing Date). FPA has agreed to use its reasonable
efforts to keep the registration statement effective for the period ending two
years after the Closing Date or such shorter period as necessary. See "THE
MERGER AGREEMENT -- Certain Additional Agreements -- Registration Rights
Agreement."
 
     Indemnification of Directors & Officers. FPA has agreed to indemnify,
defend and hold harmless, for a period of six years commencing at the Effective
Time, all current and former directors and officers of HPI and its subsidiaries
against all losses, claims, damages and liabilities, costs or expenses,
judgments, fines, penalties and amounts paid in settlement arising out of any
acts or omissions or alleged acts or omissions by them in their capacities as
such. Also, the Merger Agreement requires FPA to purchase, immediately following
the Effective Time, and maintain or cause the Surviving Corporation to maintain
for a period of six years thereafter directors' and officers' liability
insurance covering each person who was a director or officer of HPI at any time
prior to the Effective Time. See "THE MERGER AGREEMENT -- Certain Additional
Agreements."
 
     Master Strategic Arrangement for Private Practice Partnerships. Certain
health plan subsidiaries of Oxford ("Oxford health plans") and certain
subsidiaries, affiliated professional corporations and an affiliated IPA of HPI
("HPI MSOs") are parties to partnership agreements which govern the relationship
between the Oxford health plans and the providers, including provisions
regarding the compensation payable to providers for the provision of
comprehensive medical care to Oxford health plan enrollees. In connection with
the Merger, Oxford and HPI have agreed to establish certain strategic principles
under which they will enter into partnership agreements in the future in
existing and new markets (the "Strategic Agreement"). The terms of the Strategic
Agreement include, among others, (i) the partnership agreements in existence
between Oxford health plans and HPI MSOs shall remain in effect in accordance
with their terms; (ii) if Oxford and HPI agree that an HPI MSO should become a
provider for an Oxford health plan, that provider and Oxford health plan will
enter into partnership agreements containing mutually satisfactory provisions
and will become subject to the Strategic Agreement; (iii) under certain
delineated circumstances, the Oxford health plan may advise the HPI MSO of its
intention to change the compensation level payable to providers servicing health
plan enrollees; the parties have agreed to negotiate in good faith the intended
compensation changes with specified remedies if agreement is not reached; (iv)
HPI MSOs must meet certain specified conditions in order to add physicians to
provider groups which are parties to existing partnership agreements; and (v) if
HPI develops physician networks in markets where Oxford health plans operate,
the parties agree to negotiate in good faith to enter into partnership
agreements in such areas, which agreements will be in accordance with the terms
of the Strategic Agreement. The Strategic Agreement has a term of ten years with
additional five year terms upon mutual agreement of the parties and includes
specified events of termination.
 
     WellPoint Parent Memorandum of Understanding. WellPoint Parent and FPA have
agreed to develop a strategic relationship to further the delivery of quality,
cost-effective health care to enrollees of WellPoint Parent's subsidiary health
plans. The strategic relationship will focus on markets served by WellPoint
Parent's subsidiary health plans and will include possible expansion of current
contractual relationships between WellPoint Parent's health plans and FPA and
entering into new contractual relationships. The memorandum of understanding
contemplates various activities that WellPoint Parent and FPA may jointly pursue
in meeting the objectives of the relationship. The memorandum does not obligate
either party to alter any existing contractual relationship or to enter into any
definitive agreement regarding the terms of the memorandum.
 
CERTAIN FEDERAL INCOME TAX CONSEQUENCES
 
     The following summary discusses the material federal income tax
consequences of the Merger. The summary is based upon the Code, applicable
Treasury Regulations thereunder and administrative rulings and judicial
authority as of the date hereof. All of the foregoing are subject to change,
possibly with retroactive effect, and any such change could affect the
continuing validity of the discussion. The discussion assumes that holders of
shares of HPI Common Stock hold such shares as a capital asset. Further, the
discussion does not
 
                                       45
<PAGE>   50
 
address the tax consequences that may be relevant to a particular stockholder
subject to special treatment under certain federal income tax laws, such as
dealers in securities, banks, insurance companies, tax-exempt organizations,
non-United States persons, stockholders who acquired shares of HPI Common Stock
through the exercise of options or otherwise as compensation or through a
tax-qualified retirement plan, and holders of options granted under HPI's
benefit plans. This discussion does not address any consequences arising under
the laws of any state, locality or foreign jurisdiction.
 
     Neither HPI nor FPA has requested a ruling from the Internal Revenue
Service ("IRS") with regard to any of the federal income tax consequences of the
Merger and the opinions of counsel as to such federal income tax consequences
set forth below will not be binding on the IRS.
 
     General. As of the date hereof, it is intended that the Merger will
constitute a reorganization pursuant to Section 368(a) of the Code and that for
federal income tax purposes no gain or loss will be recognized by FPA, HPI or
Merger Sub. The respective obligations of the parties to consummate the Merger
are conditioned on (i) the receipt by FPA of an opinion of Pillsbury Madison &
Sutro LLP dated the Closing Date confirming that the Merger will qualify as a
reorganization within the meaning of Section 368(a) of the Code and that each of
FPA, HPI and Merger Sub will be a party to the reorganization within the meaning
of Section 368(b) of the Code and (ii) the receipt by HPI of an opinion of
Gibson, Dunn & Crutcher LLP dated the Closing Date confirming that the Merger
will qualify as a reorganization within the meaning of Section 368(a) of the
Code and that each of FPA, HPI and Merger Sub will be a party to the
reorganization within the meaning of Section 368(b) of the Code. Such opinions
will be based upon, among other things, (i) representations of HPI, FPA and
certain stockholders of HPI customarily given in transactions of this type and
(ii) the assumption that the Merger will be consummated in accordance with the
terms of the Merger Agreement.
 
     The opinions to be delivered at the Closing of Pillsbury Madison & Sutro
LLP and Gibson, Dunn & Crutcher LLP summarize the material federal income tax
consequences of the Merger, assuming that the Merger will qualify as a
reorganization within the meaning of Section 368(a) of the Code.
 
     Consequences to HPI Stockholders. Under the reorganization provisions of
the Code, no gain or loss will be recognized by holders of HPI Common Stock with
respect thereto as a result of the surrender of their shares of HPI Common Stock
in exchange for shares of FPA Common Stock pursuant to the Merger (except as
discussed below with respect to cash received in lieu of fractional shares). The
aggregate tax basis of the shares of FPA Common Stock received in the Merger
(including any fractional shares of FPA Common Stock deemed received) will be
the same as the aggregate tax basis of the shares of HPI Common Stock
surrendered in exchange therefor in the Merger. The holding period of the shares
of FPA Common Stock received (including the holding period of fractional shares
of FPA Common Stock deemed received) will include the holding period of shares
of HPI Common Stock surrendered in exchange therefor.
 
     Fractional Shares. If a holder of shares of HPI Common Stock receives cash
in lieu of a fractional share interest in FPA Common Stock in the Merger, such
fractional share interest will be treated as having been distributed to the
holder, and such cash amount will be treated as received in redemption of the
fractional share interest. Under Section 302 of the Code, if such redemption is
"not essentially equivalent to a dividend" after giving effect to the
constructive ownership rules of the Code, the holder will generally recognize
capital gain or loss equal to the cash amount received for the fractional share
of FPA Common Stock reduced by the portion of the holder's tax basis in shares
of HPI Common Stock surrendered that is allocable to the fractional share
interest in FPA Common Stock. Under these rules, a stockholder of HPI should
recognize capital gain or loss on the receipt of cash in lieu of a fractional
share interest in FPA Common Stock. The capital gain or loss will be long-term
capital gain or loss if the holder's holding period in the fractional share
interest is more than one year. Under recently proposed tax legislation,
long-term capital gain or loss treatment would apply only if the holding period
is more than eighteen months.
 
     Consequences to HPI, FPA and Merger Sub. None of HPI, FPA or Merger Sub
will recognize gain or loss as a result of the Merger.

     THE PRECEDING DISCUSSION DOES NOT PURPORT TO BE A COMPLETE ANALYSIS OR
DISCUSSION OF ALL POTENTIAL TAX EFFECTS RELEVANT TO THE MERGER. THUS, HPI
STOCKHOLDERS ARE URGED TO CONSULT THEIR OWN TAX ADVISORS AS TO THE SPECIFIC TAX
CONSEQUENCES TO THEM OF THE MERGER, INCLUDING TAX RETURN REPORTING REQUIREMENTS,
THE APPLICABILITY AND EFFECT OF FEDERAL, STATE, LOCAL, AND OTHER APPLICABLE TAX
LAWS AND THE EFFECT OF ANY PROPOSED CHANGES IN THE TAX LAWS.
 
ACCOUNTING TREATMENT
 
     The Merger will be accounted for using the "pooling of interests" method of
accounting pursuant to Accounting Principles Board Opinion No. 16, as amended
("APB No. 16"). The "pooling of interests" method of accounting assumes that the
combining companies have been merged from inception, and the historical
financial statements for periods prior to consummation of the Merger are
restated as though the companies had been combined from inception. The restated
financial statements are adjusted to conform the accounting policies of the
separate companies. See "SELECTED HISTORICAL AND PRO FORMA INFORMATION -- PRO
FORMA CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED) OF FPA MEDICAL
MANAGEMENT, INC. AND SUBSIDIARIES." It is a condition to the Merger that each of
FPA and HPI receive letters from their respective independent auditors stating
that the Merger will qualify as a "pooling of interests" for accounting and
financial reporting purposes.
 
RESALE OF FPA COMMON STOCK BY AFFILIATES
 
     FPA Common Stock to be issued to stockholders of HPI in connection with the
Merger has been registered under the Securities Act pursuant to the Registration
Statement of which this Proxy Statement/Prospectus forms a part. FPA Common
Stock received by the stockholders of HPI upon consummation of the Merger will
be freely transferable under the Securities Act, except for shares issued to any
person who may be deemed an "Affiliate" (as defined below) of HPI or FPA within
the meaning of Rule 145 promulgated under the Securities Act ("Rule 145").
Affiliates are generally defined as persons who control, are controlled by, or
are under common control with HPI or FPA at the time of the HPI Special Meeting
(generally, directors, certain executive officers and major stockholders).
Affiliates of HPI or FPA may not sell their shares of FPA Common Stock acquired
in connection with the Merger, except pursuant to an effective registration
statement under the Securities Act covering such shares or in compliance with
Rule 145 or another applicable exemption from the registration requirements of
the Securities Act. In general, under Rule 145, for one year following the
Effective Time, an Affiliate (together with certain related persons) would be
entitled to sell shares of FPA Common Stock acquired in connection with the
Merger only through unsolicited "broker transactions" or in transactions
directly with a "market maker," as such terms are defined in Rule 144
promulgated under the Securities Act ("Rule 144"). Additionally, the number of
shares to be sold by an Affiliate (together with certain related persons and
certain persons acting in concert) during such one-year period within any
three-month period for purposes of Rule 145 may not exceed the greater of 1% of
the outstanding shares of FPA Common Stock or the average weekly trading volume
of such stock during the four calendar weeks preceding such sale. Rule 145 would
remain available to Affiliates only if FPA remained current with its information
filings with the Commission under the Exchange Act. One year after the Effective
Time, an Affiliate would be able to sell such FPA Common Stock without such
manner of sale or volume limitations, provided that FPA was current with its
Exchange Act information filings and such Affiliate was not then an Affiliate of
FPA. Two years after the Effective Time, an Affiliate would be able to sell such
shares of FPA Common Stock without any restrictions, provided that such
Affiliate has not been an Affiliate of FPA for at least three months prior
thereto. In addition, under rules relating to "pooling of interests" accounting,
shares of FPA Common Stock issued to affiliates of HPI may not be resold by them
until combined results of operations of FPA and HPI covering at least thirty
days of operations are published. In connection with the Merger, FPA has agreed
to enter into a registration rights agreement with certain stockholders of HPI.
See "THE MERGER AGREEMENT -- Interests of Certain Persons in the Merger."

CERTAIN REGULATORY MATTERS
 
     FPA and HPI believe that the Merger does not violate the federal antitrust
laws and intend to resist vigorously any assertion to the contrary by the FTC,
the DOJ or others. Any such resistance could delay consummation of the Merger,
perhaps for a considerable period of time. FPA and HPI made their respective
filings with the FTC and the DOJ with respect to the Merger on July 29, 1997.
FPA and HPI have received written notification dated             , 1997, that
early termination of the waiting period of their respective HSR filings has been
granted. Notwithstanding the termination of the waiting period of the HSR
filings, the FTC, DOJ or others could take action under the antitrust laws,
including after the Effective Time, seeking the divestiture by FPA of all or any
part of the assets of HPI acquired in the Merger. There can be no assurance that
a challenge to the Merger on antitrust grounds will not be made or, if such a
challenge is made, that it would not be successful.
 
     Certain persons, such as states' attorneys general and private parties,
could challenge the Merger as violative of the federal antitrust laws and seek
to enjoin the consummation of the Merger and, in the case of private persons,
also seek to obtain treble damages. There can be no assurance that a challenge
to the Merger on antitrust grounds will not be made or, if such a challenge is
made, that it will not be successful. HPI does not intend to seek any further
stockholder approval or authorization of the Merger Agreement as a result of any
action that it may take to resist or resolve any FTC, DOJ or other objections,
unless required to do so by applicable law.
 
RIGHTS OF DISSENTING STOCKHOLDERS
 
     Holders of HPI Voting Securities as of the Record Date (the "Record
Holders") are entitled to appraisal rights under Section 262 of the Delaware Act
("Section 262") for such securities. The following discussion represents a
summary of the material provisions of Section 262. For additional information,
reference is made to the full text of Section 262, which is reprinted in its
entirety as Appendix C to this Proxy Statement/Prospectus. A person having a
beneficial interest in HPI Voting Securities as of the Record Date held of
record in the name of another person, such as a nominee, must act promptly to
cause the record holder to follow the steps summarized below properly and in a
timely manner to perfect the appraisal rights provided under Section 262.
 
     Under Section 262, where a merger is to be submitted for approval at a
meeting of stockholders, as in the case of the HPI Special Meeting, not less
than 20 days prior to the meeting, a constituent corporation must notify each of
the holders of its stock for which appraisal rights are available that such
appraisal rights are available and include in each such notice a copy of Section
262. THIS PROXY STATEMENT/ PROSPECTUS SHALL CONSTITUTE SUCH NOTICE TO THE RECORD
HOLDERS OF HPI COMMON STOCK AND HPI PREFERRED STOCK. ANY SUCH STOCKHOLDER WHO
WISHES TO EXERCISE SUCH APPRAISAL RIGHTS SHOULD REVIEW THE FOLLOWING DISCUSSION
AND APPENDIX C CAREFULLY, BECAUSE FAILURE TO TIMELY AND PROPERLY COMPLY WITH THE
PROCEDURES SPECIFIED WILL RESULT IN THE LOSS OF APPRAISAL RIGHTS UNDER THE
DELAWARE ACT.
 
     Under the Delaware Act, a Record Holder of HPI Voting Securities who makes
the demand described below with respect to such shares, who continuously is the
record holder of such shares through the Effective Time, who otherwise complies
with the statutory requirements set forth in Section 262 and who neither votes
in favor of approval of the Merger Agreement and the Merger nor consents thereto
in writing will be entitled to have his or her HPI Voting Securities appraised
by the Delaware Court of Chancery and to receive payment of the "fair value" of
such shares as described below. Such holders are, in such circumstances,
entitled to appraisal rights because they hold shares of a constituent
corporation to the Merger and may be required by the Merger Agreement to accept
the Merger Consideration.
 
     A Record Holder of HPI Voting Securities wishing to exercise his or her
appraisal rights must deliver to the Secretary of HPI, before the vote on the
Merger Agreement at the HPI Special Meeting, a written demand for appraisal of
his or her HPI Voting Securities. Merely voting or delivering a proxy directing
a vote against approval of the Merger Agreement and the Merger will not
constitute a demand for appraisal. A
 
                                       48
<PAGE>   53
 
written demand is essential. Such written demand must reasonably inform HPI of
the identity of the Record Holder and that such holder intends thereby to demand
appraisal of the holder's shares. All written demands for appraisal of HPI
Voting Securities should be sent or delivered to HPI at 800 Connecticut Avenue,
Norwalk, Connecticut 06854, Attention: Corporate Secretary. In addition, a
Record Holder of HPI Voting Securities wishing to exercise his or her appraisal
rights must hold such shares of record on the date the written demand for
appraisal is made and must hold such shares continuously through the Effective
Time. Stockholders who hold their HPI Voting Securities in nominee form and who
wish to exercise appraisal rights must take all necessary steps in order that a
demand for appraisal is made by the record holder of such shares and are urged
to consult with their nominee to determine the appropriate procedures for the
making of a demand for appraisal by the record holder.
 
     Within ten days after the Effective Time of the Merger, HPI, as the
surviving corporation in the Merger, must send a notice as to the effectiveness
of the Merger to each person who has satisfied the appropriate provisions of
Section 262 and who is entitled to appraisal rights under Section 262. Within
120 days after the Effective Time, any Record Holder of HPI Voting Securities
who has complied with the requirements for exercise of appraisal rights will be
entitled, upon written request, to receive from the Surviving Corporation a
statement setting forth (i) the aggregate number of shares of HPI Common Stock
and HPI Preferred Stock not voted in favor of the Merger Agreement and with
respect to which demands for appraisal have been received and (ii) the aggregate
number of holders of such shares. Any such statement must be mailed within ten
days after a written request therefor has been received by the Surviving
Corporation.
 
     Within 120 days after the Effective Time, but not thereafter, the Surviving
Corporation or any Record Holder of HPI Voting Securities who has complied with
the foregoing procedures and who is entitled to appraisal rights under Section
262 may file a petition in the Delaware Court of Chancery demanding a
determination of the "fair value" of such shares. The Surviving Corporation is
not under any obligation to file a petition with respect to the appraisal of the
"fair value" of the HPI Voting Securities and neither FPA nor HPI presently
intends that the Surviving Corporation file such a petition. Accordingly, it is
the obligation of the stockholders to initiate all necessary action to perfect
their appraisal rights within the time prescribed in Section 262. A Record
Holder of HPI Voting Securities will fail to perfect, or effectively lose, his
or her right to appraisal if no petition for appraisal of shares of HPI Voting
Securities is filed within 120 days after the Effective Time.
 
     If a petition for an appraisal is timely filed, after a hearing on such
petition, the Delaware Court of Chancery will determine the holders of HPI
Voting Securities entitled to appraisal rights and will appraise the "fair
value" of the HPI Voting Securities, exclusive of any element of value arising
from the accomplishment or expectation of the Merger. Stockholders considering
seeking appraisal should be aware that the "fair value" of their HPI Voting
Securities as determined under Section 262 could be more than, the same as, or
less than the value of the Merger Consideration they would have received if they
did not seek appraisal. The Delaware Supreme Court has stated that "proof of
value by any techniques or methods which are generally considered acceptable in
the financial community and otherwise admissible in court" should be considered
in the appraisal proceedings. In addition, Delaware courts have decided that the
statutory appraisal remedy, depending on factual circumstances, may or may not
be a dissenter's exclusive remedy.
 
     The Delaware Court of Chancery will determine the amount of interest, if
any, to be paid upon the amounts to be received by persons whose HPI Voting
Securities have been appraised. The costs of the action may be determined by
such court and taxed upon the parties as the court deems equitable. The Delaware
Court of Chancery may also order that all or a portion of the expenses incurred
by any holder of HPI Voting Securities in connection with an appraisal,
including without limitation, reasonable attorneys' fees and the fees and
expenses of experts utilized in the appraisal proceeding, be charged pro rata
against the value of all of the HPI Voting Securities entitled to appraisal.
 
     If any Record Holder of HPI Voting Securities who demands appraisal of his
or her shares under Section 262 fails to perfect, or effectively withdraws or
loses, his or her right to appraisal, as provided in the Delaware Act, the HPI
Voting Securities of such stockholder will be deemed to receive Merger
Consideration in accordance with the Merger Agreement. A holder may withdraw his
or her demand for appraisal by
 
                                       49
<PAGE>   54
 
delivering to the Surviving Corporation a written withdrawal of his or her
demand for appraisal and acceptance of the Merger, except that any such attempt
to withdraw made more than 60 days after the Effective Time will require the
written approval of the Surviving Corporation. Failure to follow the steps
required by Section 262 of the Delaware Act for perfecting appraisal rights may
result in the loss of such rights.
 
     Any Record Holder of HPI Voting Securities who has duly demanded an
appraisal in compliance with Section 262 will not, after the Effective Time, be
entitled to vote the HPI Voting Securities subject to such demand for any
purpose or be entitled to the payment of dividends or other distributions on
those shares (except dividends or other distributions payable to holders of
record of shares of HPI Voting Securities as of a date prior to the Effective
Time).
 
                                  THE PAYMENTS
 
     The following is a summary of certain payments and benefits (the
"Payments") that will be paid to and received by Charles G. Berg, President and
Chief Executive Officer of HPI, in connection with the termination at the
Effective Time of the HPI Employment Agreement.
 
     Under the HPI Employment Agreement, Mr. Berg is entitled to receive the
following Payments upon the termination of such agreement, if such termination
results from a material alteration of Mr. Berg's duties, which the HPI Board has
determined will occur as a result of the Merger: (a) a lump-sum cash payment of
$350,000 and (b) the acceleration of the vesting of his unvested HPI Options to
purchase 239,150 shares of HPI Common Stock. The value of such vesting
acceleration is estimated to be approximately $460,000. See "THE
MERGER -- Interests of Certain Persons in the Merger." By voting FOR approval of
the Payments, HPI stockholders will be approving the payment of all of the
Payments to Mr. Berg.
 
     Section 280G of the Code and the proposed regulations promulgated
thereunder ("Section 280G") will disallow the deduction by HPI of any portion of
the Payments characterized as an "excess parachute payment" as described below.
Also, Section 4999 of the Code will impose a 20% nondeductible excise tax on Mr.
Berg with respect to any portion of the Payments characterized as an "excess
parachute payment." To be considered parachute payments, the Payments must (i)
be in the nature of compensation, (ii) be contingent on a change in ownership of
HPI and (iii) have a present value, when combined with all other such payments
(the "Total Payments"), that equals or exceeds three times the average annual
compensation paid to Mr. Berg by HPI over the term of his employment with HPI
(the "Employment Period"). The Total Payments may include all or a portion of
the $300,000 payment to Mr. Berg to be made by FPA pursuant to the FPA
Employment Agreement. See "THE MERGER -- Interests of Certain Persons in the
Merger."
 
     If the Total Payments are considered parachute payments, they will be
treated as "excess parachute payments" to the extent the present value of such
payments exceeds the average annual compensation paid to Mr. Berg over the
Employment Period.
 
     The Payments appear to be in the nature of compensation to Mr. Berg. A
change in ownership of HPI will occur as a result of the Merger, a necessary
precondition to Mr. Berg's right to receive the Payments, and the present value
of the Payments, when combined with all other such payments to Mr. Berg, will
exceed three times the average annual compensation paid to Mr. Berg over the
Employment Period. Accordingly, a portion of the Payments may constitute excess
parachute payments unless exempted in the manner described below.
 
     The adverse federal income tax consequences to HPI and to Mr. Berg under
Sections 280G and 4999 of the Code may be avoided if the Payments are approved
by a separate vote of disinterested stockholders owning in excess of 75% of the
HPI Voting Securities, voting together, not held, directly or indirectly, by Mr.
Berg or certain members of his family, after adequate disclosure to all such
stockholders of all material facts concerning the Payments. If approved, the
Payments are no longer includable in the calculation of the Total Payments and,
as a result, the maximum Total Payments will be reduced to a level below the
threshold such that none of the Total Payments could be considered a parachute
payment. The disclosure set forth in this Proxy Statement/Prospectus is intended
as adequate disclosure to all HPI stockholders of all material facts concerning
the Payments.
 
                                       50
<PAGE>   55
 
     For purposes of the stockholder vote discussed above, any stockholder of
HPI who is not an individual may exercise its vote through any person authorized
by the entity to vote such shares. However, if a substantial portion of the
assets of such entity consists of HPI Common Stock or HPI Preferred Stock, in
general, approval of the Payments must be made by a separate vote of the persons
who hold, immediately before consummation of the Merger, in excess of 75% of the
voting power of such entity.
 
     THE BOARD OF HPI HAS APPROVED THE PAYMENTS TO MR. BERG (WITH MR. BERG
ABSTAINING), SUBJECT TO STOCKHOLDER APPROVAL, AND RECOMMENDS A VOTE "FOR" THE
PROPOSAL TO PAY THE PAYMENTS TO MR. BERG.

                     COMPARISON OF RIGHTS OF HOLDERS OF HPI
                              AND FPA COMMON STOCK
 
     Both FPA and HPI are Delaware corporations and the rights of their
respective stockholders are governed by the Delaware Act and their Certificates
of Incorporation and Bylaws. In addition, the rights of the HPI stockholders are
affected by the 1994 Securities Purchase Agreement. If the Merger is
consummated, HPI stockholders will become stockholders of FPA, and their rights
will be governed by the Certificate of Incorporation and Bylaws of FPA. The
following is a brief summary of certain differences between the rights of HPI
stockholders and FPA stockholders and is qualified in its entirety by reference
to the relevant provisions of the Delaware Act, FPA's Certificate of
Incorporation and Bylaws, HPI's Certificate of Incorporation and Bylaws and the
1994 Securities Purchase Agreement.
 
PREFERRED STOCK
 
     The Boards of Directors of FPA and HPI are authorized to provide for the
issuance of shares of preferred stock, in one or more series, and to fix for
each such series such voting powers, designations, preferences and relative,
participating, optional or other special rights, and such qualifications,
limitations or restrictions, as are stated in the resolution adopted by the
Board of Directors providing for the issuance of such series and as permitted by
the Delaware Act. FPA currently has authorized 2,000,000 shares of preferred
stock, $.001 par value; HPI currently has authorized 50,000 shares of preferred
stock, $.001 par value. FPA has not authorized or issued any shares of preferred
stock. HPI has issued and outstanding 25,000 shares of Series A Convertible
Preferred Stock and 25,000 shares of Series B Convertible Preferred Stock. A
condition to the consummation
 
                                       51
<PAGE>   56
 
of the Merger is the conversion, prior to the Effective Time, of the issued and
outstanding shares of HPI Preferred Stock into HPI Common Stock, which HPI
Common Stock will subsequently be converted into FPA Common Stock. Each of
WellPoint and Oxford has agreed to convert its outstanding shares of HPI
Preferred Stock to HPI Common Stock prior to the Effective Time. As a result of
these transactions, the current holders of HPI Preferred Stock will no longer
enjoy the special dividend, voting and liquidation preferences and rights set
forth in the HPI Certificate of Incorporation.
 
BOARD OF DIRECTORS
 
     FPA's Certificate of Incorporation provides that the FPA Board shall have
not less than three nor more than twelve members, as determined from time to
time by resolution of the board. Currently, the FPA Board consists of seven (7)
members. HPI's Certificate of Incorporation provides that the number of
directors on the HPI Board shall be specified in HPI's Bylaws. The HPI Bylaws
provide that the Board shall have one or more members as determined by a
majority of the Board. Currently, the HPI Board consists of five (5) members.
The 1994 Securities Purchase Agreement provides that so long as each of Oxford
and WellPoint beneficially owns at least 20% of the outstanding shares of HPI
Common Stock (assuming conversion of the outstanding shares of HPI Preferred
Stock beneficially owned by such stockholder), each of Oxford and WellPoint will
be entitled to nominate two directors to the HPI Board. In addition, for so long
as certain individual investors collectively own at least 10% of the outstanding
shares of HPI Common Stock, the representative of a majority in interest of the
individual investors (the "Representative") shall be entitled to nominate one
director to the HPI Board. Currently, each of Oxford and WellPoint beneficially
owns in excess of 20%, and the individual investors collectively own in excess
of 10%, of the HPI Common Stock, so that these provisions are in effect.
 
     FPA's and HPI's Bylaws provide that any or all directors may be removed
with or without cause by the holders of a majority of shares then entitled to
vote at an election of directors. HPI's Bylaws also provide that a director may
be removed for cause by vote of a majority of the HPI Board. The 1994 Securities
Purchase Agreement provides that if any of Oxford, WellPoint or the
Representative notifies the HPI stockholders that (i) such person or
Representative wishes to remove a director nominated by it or (ii) if any of
such stockholders no longer owns the requisite percentage of shares required to
maintain such nomination rights, all such stockholders shall vote their shares
in favor of such removal if a vote is otherwise required.
 
     HPI's Bylaws provide that a vacancy on the HPI Board may be filled by a
majority vote of the directors then in office, even if less than a quorum, or by
a sole remaining director. HPI's Bylaws also provide that a vacancy created by
the removal of a director may be filled by a vote of the holders of a majority
of the outstanding shares of capital stock of HPI entitled to vote thereon.
FPA's Certificate of Incorporation provides that a vacancy on the FPA Board
shall be filled solely by the affirmative vote of a majority of the remaining
directors then in office, even though less than a quorum, or by a sole remaining
director.
 
     HPI's Bylaws provide that directors shall be elected by a plurality of
votes cast at annual meetings of stockholders (and holders of HPI's Preferred
Stock shall have the same right to vote as holders of HPI's Common Stock on an
as-converted basis) with each director serving until the next annual meeting of
stockholders and until his successor is duly elected and qualified or until his
earlier death, resignation or removal or as described above pursuant to the 1994
Securities Purchase Agreement. FPA's Bylaws provide for a staggered Board of
Directors, with the directors of FPA divided into three classes, as nearly equal
in number as possible. Each director on the FPA Board is elected to serve a term
of three years and until his successor is duly elected and qualified.
 
BYLAWS
 
     FPA's Certificate of Incorporation grants the FPA Board the power to
repeal, alter, amend or rescind FPA's Bylaws. FPA's Bylaws permit FPA's
stockholders to alter, amend, repeal or adopt the same. HPI's Certificate of
Incorporation provides that the HPI Board may adopt, repeal, alter, amend or
rescind HPI's Bylaws, subject to the right of the holders of a majority of the
outstanding stock of HPI, by vote at an annual or special meeting, to amend,
alter or repeal any Bylaw made by the Board.
 
                                       52
<PAGE>   57
 
STOCKHOLDER MEETINGS
 
     HPI's Bylaws provide that special meetings of stockholders may be called by
the HPI Board. FPA's Bylaws provide that special meetings of stockholders may be
called by the President. Furthermore, FPA's Bylaws provide that such special
meeting shall be called by the President or Secretary at the request in writing
of a majority of the FPA Board or stockholders owning a majority in amount of
the entire capital stock of FPA issued and outstanding and entitled to vote.
 
     The 1994 Securities Purchase Agreement further provides that if any party
to the 1994 Securities Purchase Agreement fails to vote its shares for directors
as required therein, each other stockholder to such Agreement shall have an
irrevocable, perpetual proxy, exercisable by any of them individually, to vote
such shares of HPI securities in accordance with the 1994 Securities Purchase
Agreement.
 
INDEMNIFICATION
 
     Under the Delaware Act, a corporation may generally indemnify its officers,
directors, employees and agents against expenses (including attorneys' fees),
judgments, fines and amounts paid in settlement of any proceedings (other than
derivative actions), if they acted in good faith and in a manner they 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 their conduct was unlawful. A similar standard is applicable in
derivative actions, except that indemnification may be made only for (1)
expenses (including attorneys' fees) and certain amounts paid in settlement and
(2) in the event the person seeking indemnification has been adjudicated liable,
amounts deemed proper, fair and reasonable by the appropriate court upon
application thereto. The Delaware Act provides that to the extent that such
persons have been successful in defense of any proceeding, they must be
indemnified by the corporation against expenses actually and reasonably incurred
in connection therewith.
 
     FPA's Certificate of Incorporation and HPI's Bylaws require indemnification
for directors and officers, their legal representatives, and persons serving at
the request of FPA as a director, officer, employee or agent of another
corporation, partnership, or other entity ("Indemnitees") for actions undertaken
in an official capacity or any other capacity.
 
     FPA's Certificate of Incorporation and HPI's Bylaws provide for the
continuation of indemnification for Indemnitees no longer employed by the
respective company (where the conduct at issue occurred while the Indemnitee was
employed by such company). FPA's Certificate of Incorporation and HPI's Bylaws
also provide for the benefits of indemnification to inure to the heirs,
executors and administrators of the Indemnitee. Furthermore, FPA's Certificate
of Incorporation and HPI's Bylaws require, as a prerequisite to indemnification
in connection with a suit initiated by the Indemnitee, that the Indemnitee
receive authorization from the Board prior to initiating the suit.
 
     FPA's Certificate of Incorporation and HPI's Bylaws grant Indemnitees the
right to receive an advance of funds from their respective company to pay for
anticipated legal costs in defending a lawsuit for which indemnification is
sought. However, to the extent required by the Delaware Act, an Indemnitee may
be required to deliver an undertaking to his respective company to the effect
that the Indemnitee will repay all amounts advanced should the Indemnitee
ultimately be determined not to be entitled to indemnification.
 
     FPA's Certificate of Incorporation provides that if an Indemnitee is not
advanced funds for anticipated costs in defending a lawsuit within thirty days
of FPA receiving a written request for such funds, the Indemnitee may sue FPA
for the unpaid amount. If the Indemnitee has delivered to FPA an undertaking to
repay such advance, FPA may not offer as a defense to such claim for indemnity
that the claimant has not met the standard of conduct for indemnification under
the Delaware Act. However, if no such undertaking has been delivered to FPA, FPA
may offer such failure to meet the standard of conduct for indemnification as a
defense. FPA may not offer as a defense to the advancement of funds that it has
not yet determined whether the Indemnitee has met the appropriate standard of
conduct. Neither HPI's Bylaws nor its Certificate of Incorporation contains
comparable provisions.

STOCKHOLDER VOTING REQUIREMENTS
 
     Under the Delaware Act, unless otherwise provided for by the Delaware Act
or a Delaware corporation's certificate of incorporation or bylaws, if a quorum
exists, action on a matter is approved by the affirmative vote of a majority of
the shares represented at a meeting and entitled to vote on the matter.
 
     Neither FPA's Certificate of Incorporation nor its Bylaws contains a
provision requiring a greater vote on any matter than required by the Delaware
Act.
 
     HPI's Certificate of Incorporation contains provisions requiring the
affirmative vote of the holders of at least 80% or more of HPI's voting shares
to amend, alter or repeal or adopt any provision inconsistent with the current
provision of the Bylaws providing that HPI's directors shall not be liable to
HPI or its stockholders for monetary damages for breach of fiduciary duty as a
director. In addition, until there are less than 5,000 shares of HPI Preferred
Stock outstanding, the approval of at least 60% of the issued and outstanding
shares of HPI Common Stock and HPI Preferred Stock, voting as a class, is
required to sell, abandon, transfer, lease or otherwise dispose of all or
substantially all of its properties or assets, merge or consolidate with or into
another corporation, voluntarily dissolve, liquidate or wind-up, authorize,
create, issue or sell any class of capital stock of HPI ranking prior to or on a
parity with the HPI Preferred Stock, alter or change the designations, rights
and preferences of the HPI Preferred Stock in any manner or authorize any
employee stock option plan or program except plans relating to not in excess of
1,450,000 shares of HPI Common Stock.
 
ACTION BY CONSENT
 
     The Delaware Act provides that, unless otherwise provided in the
Certificate of Incorporation, any action required or permitted to be taken at
any annual or special meeting of stockholders may be taken without a meeting,
without prior notice and without a vote, by written consent of the holders of
outstanding stock having not less than the minimum number of votes that would be
necessary to authorize or take such action at a meeting. Both FPA's and HPI's
Bylaws permit action by such written consent.

                              THE MERGER AGREEMENT
 
     The following is a summary of the material provisions of the Merger
Agreement not summarized elsewhere in this Proxy Statement/Prospectus. A copy of
the Merger Agreement is attached as Appendix A to this Proxy
Statement/Prospectus and is incorporated herein by reference. The following
summary does not purport to be complete and is qualified in its entirety by
reference to the Merger Agreement.
 
THE MERGER
 
     The Merger Agreement provides that, subject to the approval and adoption of
the Merger Agreement by the stockholders of HPI and the satisfaction or waiver
of other conditions to the Merger, Merger Sub will be merged with and into HPI
in accordance with the Delaware Act, whereupon the separate existence of Merger
Sub will cease and HPI will be the Surviving Corporation and a wholly owned
subsidiary of FPA.
 
     At the Effective Time:
 
          (i) Each issued and outstanding share of HPI Common Stock, except as
     provided for below, will be converted into the right to receive a number of
     shares of FPA Common Stock determined by the Exchange Ratio. For a
     discussion of the Exchange Ratio, see "THE MERGER -- Merger Consideration."
 
          (ii) Each share of HPI Common Stock and HPI Preferred Stock held in
     HPI's treasury will be canceled and extinguished and will cease to exist
     and no consideration will be delivered with respect thereto.
 
          (iii) If applicable, each outstanding share of HPI Common Stock and
     HPI Preferred Stock, the holder of which (i) has not voted in favor of the
     Merger, (ii) has perfected such holder's dissenters' rights to appraisal in
     accordance with the pertinent provisions of the Delaware Act and (iii) has
     not effectively withdrawn or lost such rights to appraisal, will not be
     converted into a right to receive shares of FPA Common Stock, but such
     holder shall be entitled only to such rights as are granted under the
     applicable provisions of the Delaware Act. See "THE MERGER -- Rights of
     Dissenting Stockholders."
 
          (iv) Each share of capital stock of Merger Sub issued and outstanding
     immediately prior to the Effective Time will be converted into and
     exchanged for one validly issued, fully paid and nonassessable share of
     common stock of the Surviving Corporation.
 
     Immediately prior to the Effective Time, HPI shall use its reasonable best
efforts to cause each issued and outstanding share of HPI Preferred Stock to be
converted into shares of HPI Common Stock in accordance with the provisions of
the relevant Certificate of Designations for such HPI Preferred Stock, and such
shares of HPI Common Stock will be converted into the right to receive shares of
FPA Common Stock as described above in subparagraph (i) of this section. The
holders of HPI Preferred Stock have agreed to convert their shares of HPI
Preferred Stock to HPI Common Stock prior to the Effective Time.
 
     At the Effective Time, present holders of HPI Common Stock and HPI
Preferred Stock will cease to have any rights as holders of such shares, other
than, if applicable, dissenters' rights to appraisal, but will have the right to
receive shares of FPA Common Stock and cash in lieu of any fractional shares of
FPA Common Stock.
 
     The Certificate of Incorporation and Bylaws of Merger Sub will be the
Certificate of Incorporation and Bylaws of the Surviving Corporation. The
directors of Merger Sub serving immediately prior to the Effective Time will be
the initial directors of the Surviving Corporation, in each case until their
respective successors are duly elected or appointed and qualified.
 
EFFECTIVE TIME
 
     The Merger will become effective on such date as the duly prepared and
executed Certificate of Merger is filed with the Secretary of State of Delaware
in accordance with the Delaware Act. The filing of the Certificate of Merger
will be made simultaneously with or as soon as practicable after the second
business day
 
                                       55
<PAGE>   60
 
immediately following the date on which all conditions contemplated by the
Merger Agreement have been fulfilled or waived or such other time as agreed
between the parties.
 
FRACTIONAL SHARES
 
     No certificates or scrip for fractional shares of FPA Common Stock will be
issued in connection with the Merger. In lieu of any such fractional share, each
holder of HPI Common Stock who would otherwise have been entitled to a fraction
of a share of FPA Common Stock upon surrender of certificates for exchange will
be entitled to receive from the Exchange Agent a cash payment equal to such
fraction multiplied by the FPA Value.
 
SURRENDER AND PAYMENT
 
     From and after the Effective Time, as required by the Merger Agreement, FPA
will make available to the Exchange Agent certificates representing the
appropriate number of shares of FPA Common Stock and cash to be paid in lieu of
fractional shares of FPA Common Stock issuable in connection with the Merger.
Promptly after the Effective Time, the Exchange Agent shall mail to each holder
of a certificate or certificates that immediately prior to the Effective Time
represented HPI Common Stock ("HPI Certificates") a letter of transmittal and
instructions for surrendering the HPI Certificates, and each holder thereof will
be entitled to receive, upon surrender to the Exchange Agent of one or more HPI
Certificates, certificates representing the number of whole shares of FPA Common
Stock into which such shares are converted in the Merger and cash in
consideration of fractional shares of FPA Common Stock, as described above.
 
TREATMENT OF STOCK OPTIONS
 
     At the Effective Time, each of the outstanding options to purchase shares
of HPI Common Stock ("HPI Options") granted under the HPI 1994 Stock Option Plan
(the "HPI Option Plan"), whether or not vested, including the HPI Options
granted to holders of Minority Options in the Roll-up Transactions, will be
canceled in exchange for a number of Shares of fully paid FPA Common Stock (the
"FPA Option Shares"), decreased to the nearest whole share, equal to the
quotient which results when the "Fair Market Value" of such option at the
Effective Time is divided by the FPA Value (the "Option Exchange"). The Fair
Market Value of the HPI Options will be determined by an investment banking
firm, selected by HPI and acceptable to FPA, by applying a variation of the
Black-Scholes option pricing model. HPI estimates that an aggregate of
          FPA Option Shares will be issued in the Merger.
 
     HPI and FPA believe that HPI has the right under the HPI Option Plan to
undertake the Option Exchange without seeking the consent of the holders of HPI
Options. However, HPI has agreed to use its reasonable best efforts to cause the
holders of HPI Options to execute prior to the Closing Date a form of
acknowledgement reasonably acceptable to FPA regarding their acceptance of the
treatment of HPI Options set forth in the Merger Agreement and described above
(the "Stock Option Acknowledgements"). FPA can terminate the agreement if HPI
does not enter into Stock Option Acknowledgment Agreements with holders of HPI
Options representing at least 80% of the total number of HPI Options. As of the
date of this Proxy Statement/Prospectus, HPI has received Stock Option
Acknowledgements with respect to     % of the total number of HPI Options.

     The Merger Agreement contains various customary representations and
warranties of each of FPA, Merger Sub and HPI (which are subject, in certain

Time) relating to, among other things, the following: (i) organization and

Effective Time, each of FPA and HPI has further agreed that prior to the
Effective Time as to itself and its subsidiaries that (unless expressly provided

or satisfied by it.
 
CERTAIN ADDITIONAL AGREEMENTS
 
     Pursuant to the Merger Agreement, FPA and HPI have made the following
additional agreements.
 
     Access to Information. Each of FPA and HPI shall, and shall cause each of
its subsidiaries, throughout the period commencing on the date of the Merger
Agreement and ending at the Effective Time, to: (i) provide the other party and
its legal and financial advisors, accountants and any other agents and
representatives (collectively, "Advisors") with full access, upon reasonable
prior notice and during normal business hours, to their respective assets,
properties, books and records, but only to the extent that such access does not
unreasonably interfere with the business and operations of FPA and HPI, as the
case may be, and its subsidiaries, and (ii) furnish promptly to such persons (x)
a copy of each report, statement, schedule and other document filed or received
by FPA or HPI, as the case may be, or any of its subsidiaries pursuant to the
requirements of federal or state securities laws or filed with any other
governmental or regulatory authority, and (y) all other information and data
concerning the business and operations of FPA or HPI, as the case may be, and
its subsidiaries as the other party or any of such other persons reasonably may
request.
 
     In the event that the Merger Agreement is terminated without the
transactions contemplated thereby having been consummated, upon the request of
FPA or HPI, as the case may be, the other party will, and will cause its
Advisors to, promptly redeliver or cause to be redelivered all copies of
documents and information furnished by FPA or HPI, as the case may be, or its
Advisors to such party and its Advisors in connection with the Merger Agreement
or the transactions contemplated thereby and destroy or cause to be destroyed
all notes, memoranda, summaries, analyses, compilations and other writings
related thereto or based thereon prepared by FPA or HPI, as the case may be, or
its Advisors.
 
     Inclusion of Shares on Nasdaq. FPA agreed to use its best efforts to cause
the shares of FPA Common Stock to be issued in the Merger in accordance with the
Merger Agreement to be approved for inclusion on Nasdaq.
 
     Regulatory and Other Approvals. Subject to the terms and conditions of the
Merger Agreement, each of HPI and FPA agreed to proceed diligently and in good
faith and to use all commercially reasonable efforts to do, or cause to be done,
all things necessary, proper or advisable to, as promptly as practicable, (i)
obtain all consents, approvals or actions of, make all filings with and give all
notices to governmental or regulatory authorities or any other public or private
third parties required of FPA, HPI or any of their subsidiaries to consummate
the Merger and the other matters contemplated hereby and (ii) provide such other
information and communications to such governmental or regulatory authorities or
other public or private third parties as the other party or such governmental or
regulatory authorities or other public or private third parties may
 
                                       58
<PAGE>   63
 
reasonably request in connection therewith. In addition to and not in limitation
of the foregoing, each of the parties agreed to (x) take promptly all actions
necessary to make the filings required of FPA and HPI or their affiliates under
the HSR Act, (y) comply at the earliest practicable date with any request for
additional information received by such party or its affiliates from the FTC or
the DOJ pursuant to the HSR Act and (z) cooperate with the other party in
connection with such party's filings under the HSR Act and in connection with
resolving any investigation or other inquiry concerning the Merger or the other
matters contemplated by the Merger Agreement commenced by the FTC, the DOJ or
any state attorney general.
 
     Employee Benefit Plans. In the Merger Agreement, FPA agreed that, for one
year after the Effective Time, FPA shall, or shall cause the Surviving
Corporation to, provide employee benefit plans and programs for the benefit of
employees and former employees of HPI ("HPI Employees"), which, in the
aggregate, are no less favorable than the HPI employee benefit plans and
programs in effect immediately prior to the Effective Time. FPA further agreed
that, for the two year period beginning on the date one year following the
Effective Time, FPA shall, or shall cause the Surviving Corporation to, provide
HPI Employees with employee benefit plans and programs that are no less
favorable in the aggregate to those provided from time to time to FPA employees
of comparable status and seniority. Except as specified in the Merger Agreement,
with respect to such benefits, past service, compensation and expense credits of
such HPI Employees shall be recognized, whenever reasonably possible, consistent
with the terms of such plans and programs, for all purposes under such plans and
each employee or fringe benefit plan or program available to HPI Employees as
contemplated hereby shall be applied to such HPI Employees.
 
     FPA agreed to honor, and agreed to cause the Surviving Corporation to
honor, without modification, all existing employment, severance, consulting and
salary continuation agreements between HPI and any current or former officer,
director, employee or consultant to HPI.
 
     Directors' and Officers' Indemnification and Insurance. FPA agreed to
purchase and maintain, for a period of six years following the Effective Time,
policies of directors' and officers' liability insurance covering current and
former directors, officers and employers of HPI with respect to claims arising
from facts or events that occurred on or prior to the Effective Time, providing
at least the same coverage and amounts and containing terms that are no less
advantageous to the insured parties as those in effect immediately prior to the
Effective Time for officers and directors of FPA. FPA agreed to indemnify all
past or present directors, officers, employees, trustees and agents of HPI
against any liability or losses (including attorney's fees for counsel who are
reasonably acceptable to FPA) any of them may incur because of any claim brought
against them prior to or within six years from the Effective Time as officers,
directors, employees, trustees or agents of HPI, and in connection therewith,
agreed to advance attorney's fees to them to defend any such claim; provided
that FPA shall be entitled to cooperate in the defense of any such matter; and
provided, further, that FPA shall not be liable for any settlement effected
without its written consent (which consent shall not be unreasonably withheld);
and provided, further, that FPA shall not be obligated pursuant to the Merger
Agreement to pay the fees and disbursements of more than one counsel for all
Indemnified Parties in any single action, except to the extent that, in the
opinion of counsel for the Indemnified Parties, two or more of such Indemnified
Parties have conflicting interests in the outcome of such action. FPA may obtain
directors' and officers' liability insurance covering its obligations under this
Section.
 
     Expenses. Whether or not the Merger is consummated, all costs and expenses
incurred in connection with the Merger Agreement and the transactions
contemplated thereby shall be paid by the party incurring such cost or expense.
 
     Pooling of Interests. FPA and HPI agreed that from and after the date of
the Merger Agreement and until the Effective Time, neither FPA nor HPI nor any
of their respective subsidiaries or other affiliates shall knowingly take any
action, or knowingly fail to take any action, that would jeopardize the
treatment of FPA's acquisition of HPI as a "pooling of interests" for accounting
purposes. Following the Effective Time, FPA shall use its best efforts to
conduct the business of the Surviving Corporation, and shall cause the Surviving
Corporation to use its best efforts to conduct its business, in a manner that
would not jeopardize the characterization of the Merger as a "pooling of
interests" for accounting purposes.
 
                                       59
<PAGE>   64
 
     Brokers or Finders. Each of FPA and HPI represented that no broker, finder
or investment banker is entitled to any broker's, finder's or other fee or
commission in connection with any of the transactions contemplated by the Merger
Agreement, except Smith Barney, whose fees and expenses will be paid by HPI in
accordance with HPI's agreement with such firm.
 
     Fulfillment of Conditions. Subject to the terms and conditions of the
Merger Agreement, each of FPA and HPI agreed to take or cause to be taken all
steps necessary or desirable and proceed diligently and in good faith to satisfy
each condition to the other's obligations contained in the Merger Agreement and
to consummate and make effective the transactions contemplated by the Merger
Agreement, and further agreed that neither FPA nor HPI will, nor will it permit
any of its subsidiaries to, take or fail to take any action that could be
reasonably expected to result in the nonfulfillment of any such condition.
 
     No Solicitations. Prior to the Effective Time, HPI agreed that (a) neither
it nor any of its subsidiaries shall, and it shall use its best efforts to cause
its respective Representatives not to, initiate, solicit or encourage, directly
or indirectly, any inquiries or the making or implementation of any proposal or
offer (including, without limitation, any proposal or offer to its stockholders)
with respect to a merger, consolidation or other business combination including
HPI or any of its subsidiaries or any acquisition or similar transaction
(including, without limitation, a tender or exchange offer) involving the
purchase of (i) all or any portion of the assets of HPI and its subsidiaries
taken as a whole, (ii) any of the outstanding shares of HPI Common Stock or
Preferred Stock or (iii) any of the outstanding shares of the capital stock of
any subsidiary of HPI (any such proposal or offer being hereinafter referred to
as an "Alternative Proposal"), or engage in any negotiations concerning, or
provide any confidential information or data to, or have any discussions with,
any person or group relating to an Alternative Proposal (excluding the
transactions contemplated by the Merger Agreement), or otherwise facilitate any
effort or attempt to make or implement an Alternative Proposal and (b) it will
notify FPA immediately if any such inquiries, proposals or offers are received
by, any such information is requested from, or any such negotiations or
discussions are sought to be initiated or continued with, it or any such person
or group except for the Roll-up Transactions.
 
     HPI Stockholder Agreements. FPA, HPI, Oxford and WellPoint are parties to a
Stockholder Agreement whereby Oxford and WellPoint have delivered irrevocable
proxies to FPA to vote all of their HPI Voting Securities for the approval and
adoption of the Merger Agreement and the transactions contemplated thereby.
 
     FPA and HPI Affiliates. Each of FPA and HPI have delivered a letter to the
other identifying all persons who may be deemed to be affiliates for purposes of
Accounting Series Release 135 ("ASR 135"). On or prior to a date that is five
days prior to the Closing Date, (i) HPI will deliver a letter to FPA identifying
all persons who may be deemed affiliates of HPI under Rule 145, including,
without limitation, all directors and executive officers of HPI, and (ii) it
shall advise the persons identified in such letter of the resale restrictions
imposed by applicable securities laws. Each of FPA and HPI agreed to use its
reasonable best efforts to obtain as soon as practicable after the date of the
Merger Agreement from affiliates of FPA and HPI an agreement that such persons
will comply with the provisions of ASR 135 and in any event not later than July
31, 1997, an agreement not to sell shares of FPA Common Stock or HPI Common
Stock and Preferred Stock in an amount which would contravene the provisions of
ASR 135 until combined results of operations of FPA and HPI covering at least 30
days of combined operations are made public. Oxford and WellPoint have agreed to
provide such agreements. FPA has agreed to keep current its filings under the
Exchange Act for purposes of reliance upon the resale provisions of Rule 145.
 
     Registration Rights Agreement. In the Merger Agreement, FPA agreed to enter
into a registration rights agreement with Oxford, WellPoint, and Messrs. Berg,
Phillips, Conlin and Wiggins (the "Selling Stockholders") pursuant to which FPA
will file a registration statement with the Commission as soon as practicable
after the Closing Date covering the shares received in the Merger by the Selling
Stockholders (and no other shares of FPA Common Stock) and use its reasonable
efforts to cause such registration statement to be declared effective on or
prior to 90 days after the Closing Date (but no earlier than 60 days following
the Closing Date). FPA has agreed to use its reasonable efforts to keep the

ROLL-UP TRANSACTIONS
 
     HPI has affiliated with group practices and IPAs through subsidiaries (the
"HPI Subsidiaries"). The physician-owners of the group practices and IPAs own
shares in HPI Subsidiaries with which they contract to provide health care
services. In each case, the physician-owners own less than a 30% interest in
such subsidiary (the "Minority Shares"). Each of the HPI Subsidiaries has also
granted stock options to purchase shares of common stock of the HPI Subsidiary
to certain of its employees (the "Minority Options"). Holders of Minority Shares
and/or Minority Options are referred to herein as "Minority Holders."
Shareholder agreements with the physician-owners and the stock option plans for
each HPI Subsidiary grant HPI the right to exchange the Minority Shares and
Minority Options for HPI Common Stock and HPI Options, respectively, of equal
value (the "Roll-up Transactions").
 
     In the Merger Agreement, HPI agreed to exercise its right and deliver
roll-up notices to each of the Minority Holders, which notices serve to inform
the Minority Holders of HPI's intention to undertake the Roll-up Transactions.
The Roll-up Transactions contemplate the exchange, immediately prior to the
Effective Time, of the Minority Shares and Minority Options with respect to each
HPI Subsidiary for HPI Common Stock and HPI Options based on the fair value of
such stock and options (the "Subsidiary Value"). HPI has delivered such notices
and has reached agreement with the Minority Holders of each HPI Subsidiary with
regard to the Subsidiary Value. As a result of such valuations, HPI will issue
in connection with the Roll-up Transactions, immediately prior to the Effective
Time,           shares of HPI Common Stock and HPI Options to purchase
          shares of HPI Common Stock.
 
     At the Effective Time, holders of such newly issued shares of HPI Common
Stock and HPI Options will have the right to receive shares of FPA Common Stock
on the same terms and conditions as other holders of HPI Common Stock and HPI
Options at the Effective Time. See "THE MERGER -- Merger Consideration" and "THE
MERGER AGREEMENT -- Treatment of Stock Options."

TERMINATION
 
     The Merger Agreement may be terminated and the transactions contemplated
thereby may be abandoned whether prior to or after the approval of the
stockholders of HPI: (i) by either FPA or HPI upon written notice to the
non-terminating party by the terminating party at any time after October 28,
1997, if the Merger has not been consummated on or prior to such date otherwise
than on account of delay or default on the part of the terminating party, except
that the non-terminating party may extend such date for an additional 30 days if
all required statutory approvals have not been obtained and, in the event FPA is
the non-terminating party, if the Roll-up Transactions have not been concluded;
(ii) if any condition to closing the Merger is not satisfied, other than as a
result of the conduct of the party whose obligation it was to obtain such
condition; (iii) if there has been a material breach of any representation,

<PAGE>   67
 
HPI; (v) HPI may terminate the Merger Agreement if the FPA Value is less than

EFFECT OF TERMINATION
 
     If the Merger Agreement is validly terminated by either HPI or FPA pursuant
to the Merger Agreement, the Merger Agreement will forthwith become void and
there will be no further obligation on the part of either HPI or FPA (or any of
their respective Representatives or affiliates), except (i) that certain
provisions of the Merger Agreement will continue to apply following any such
termination and (ii) that nothing contained therein shall relieve any party
thereto from liability for willful breach or a knowing violation by such party
of its representations, warranties, covenants or agreements contained in the
Merger Agreement.
 
AMENDMENT
 
     The Merger Agreement may not be amended except by action taken by or on
behalf of the respective boards of directors of the parties thereto or duly
authorized committees thereof and then only by a written instrument duly
executed by or on behalf of each party thereto and in compliance with applicable
law.
 
WAIVER
 
     At any time prior to the Effective Time, any party to the Merger Agreement,
by action taken by or on behalf of its board of directors, may to the extent
permitted by applicable law (i) extend the time for the performance of any of
the obligations or other acts of the other parties thereto, (ii) waive any
inaccuracies in the representations and warranties of the other parties thereto
contained therein or in any document delivered pursuant thereto or (iii) waive
compliance with any of the covenants, agreements or conditions of the other
parties thereto contained therein, except that after the vote of HPI
stockholders with respect to the Merger Agreement, the formula for determining
the Exchange Ratio shall not be changed from that provided in the Merger
Agreement. No such extension or waiver shall be effective unless set forth in a
written instrument duly executed by or on behalf of the party extending the time
of performance or waiving any such inaccuracy or non-compliance.

                 SELECTED HISTORICAL AND PRO FORMA INFORMATION
 
                        PRO FORMA CONDENSED CONSOLIDATED
                      FINANCIAL STATEMENTS (UNAUDITED) OF
                 FPA MEDICAL MANAGEMENT, INC. AND SUBSIDIARIES
 
     The following pro forma condensed consolidated balance sheet of FPA as of
March 31, 1997 and the pro forma condensed consolidated statements of operations
for the three years in the period ended December 31, 1996 and the three months
ended March 31, 1997 give effect, to the extent set forth below, to the
following consummated and probable transactions.
 
  Consummated Transactions:
 
     (1) The acquisition of Physicians First, Inc. ("PFI") (effective June 1,
1996).
 
     (2) The acquisition of Foundation Health Medical Services and Affiliates
         ("FHMS") (effective November 29, 1996).
 
  Probable Transaction:
 
     (1) The proposed merger of FPA and HPI (the "Merger").
 
     The Merger is reflected as of March 31, 1997 for the pro forma condensed
consolidated balance sheet. The Consummated Transactions are reflected as of
January 1, 1996 in the pro forma condensed consolidated statements of
operations. The Roll-up Transactions and the conversion of HPI Preferred Stock
into HPI Common Stock are reflected as of January 1, 1996 in the pro forma
condensed consolidated statements of operations and as of March 31, 1997 in the
pro forma condensed consolidated balance sheet. The Merger is reflected as of
January 1, 1994 in the pro forma condensed consolidated statements of
operations. The pro forma information is based on the respective historical
financial statements of the companies involved in the Consummated Transactions
and the Merger, giving effect to the Merger under the pooling of interests
method of accounting and the Consummated Transactions under the purchase method
of accounting, and the assumptions and adjustments described in the accompanying
notes to the pro forma condensed consolidated financial statements.
 
     The pro forma condensed consolidated financial statements have been
prepared by the management of FPA based upon the unaudited financial statements
of FPA and HPI as of March 31, 1997 and for the three months then ended, the
audited financial statements of FPA and HPI as of December 31, 1996 and for each
of the three years in the period then ended, and the unaudited results of
operations for PFI and FHMS up to their respective acquisition dates.
 
     Management of FPA does not believe that the pro forma condensed
consolidated financial statements are indicative of the results that actually
would have occurred if the combinations had been in effect on the dates
indicated or which may be obtained in the future. The pro forma condensed
consolidated financial statements should be read in conjunction with the
separate historical consolidated financial statements and accompanying notes of
FPA, HPI, PFI and FHMS.

               FPA NOTES TO THE PRO FORMA CONDENSED CONSOLIDATED
                        FINANCIAL STATEMENTS (UNAUDITED)
 
     FPA consummated the purchase of PFI effective June 1, 1996 for $21,591,541
consisting of cash, FPA Common Stock and debt; and the purchase of FHMS for
$111,000,000 consisting of cash, FPA Common Stock and debt. These completed
acquisitions by FPA were accounted for under the purchase method. The merger of
Sterling with FPA was consummated in October 1996 and the merger of AHI with FPA
was consummated in March 1997. Both of these mergers were accounted for as a
pooling of interests and FPA's financial statements have been restated to take
into account financial information and data of Sterling and AHI for all periods
presented. Additionally, FPA proposes to merge with HPI by issuing FPA common
stock in exchange for all of the outstanding common stock of HPI. It is
contemplated that the Merger will be accounted for as a pooling of interests.
The following adjustments are necessary to reflect the pro forma effects of the
FPA consummated and probable transactions.
 
     Certain of the entities included in the pro forma condensed consolidated
financial statements are professional corporations in which FPA is unable to own
a majority interest due to certain state laws which prohibit the corporate
practice of medicine. Such entities are included in the pro forma condensed
consolidated financial statements due to the fact FPA consolidates these
professional corporations in the consolidated financial statements of FPA. These
professional corporations are consolidated by FPA because FPA has direct or
indirect unilateral and perpetual control over the assets and operations of the
professional corporations, other than by means of owning the majority of the
voting stock of the professional corporations. The shareholder/director of each
of these professional corporations which are affiliated with FPA has entered
into a succession agreement which requires such shareholder/director to sell to
a designee of FPA such shareholder/director's shares of stock if such
shareholder/director is terminated from FPA. This ensures unilateral and
perpetual control over these professional corporations by FPA. As such, due to
the parent-subsidiary relationship under generally accepted accounting
principles, FPA consolidates the financial statements of these professional
corporations. FPA believes that consolidation of the financial statements of
these professional corporations is necessary to present fairly the financial
position and results of operations of FPA.
 
     (A)  Nonrecurring costs estimated to be $15,500,000 will be recorded in
          connection with the Merger. These costs consist primarily of certain
          employee termination costs, financial advisory fees, professional fees
          and restructuring costs. Because such costs are nonrecurring, they
          have not been recorded in the accompanying unaudited pro forma
          condensed consolidated statements of operations. However, such costs
          will be expensed in the first period following the consummation of the
          Merger.
 
     (B)  As a result of FPA's acquisition, PFI receives fully delegated
          capitation revenue from Physicians Corporation of America, the seller,
          based on the acquisition agreement with FPA, rather than only primary
          care capitation as is reflected in this historical statement of
          operations of PFI. The incremental revenue which PFI would have
          received under this fully delegated contract was approximately
          $31,000,000 for the five months ended May 31, 1996 (date of
          acquisition). Additionally, there would have been a corresponding
          increase in medical services expense and general and administrative
          expense for the provision of hospital and specialty care services
          under this fully delegated contract.

          acquisitions of PFI and FHMS on FPA's statement of operations, the

</TABLE>
 
        -----------------------
 
        (1) The amortization period of the identifiable intangible assets is
            based on the period of estimated future economic benefit as
            determined by FPA in conjunction with independent valuation
            analyses.
 
        (2) The total balance of the goodwill and intangibles at January 1, 1996
            would have been approximately $196,053,338 and $6,164,019,
            respectively, related to PFI and FHMS.
 
        (3) It is expected that substantially all of the excess purchase price
            over the net assets acquired in connection with the acquisition of
            the FHMS entities will be allocated to the Foundation Payor
            agreements which have terms of 30 years. As the value of the Payor
            agreements will be amortized over 30 years, the same amortization
            period as goodwill, and there would be no difference in the
            amortization expense, no amount has been allocated between the
            goodwill and the Payor agreements for the purposes of the pro forma
            condensed consolidated financial statements.
 
     (D)  Reflects the increase in interest expense as a result of the notes
          issued in connection with the acquisitions of PFI and FHMS. The debt
          in the amount of approximately $116,000,000 that was issued or assumed
          in connection with the FHMS acquisition bears interest at LIBOR plus
          .45%. A one-eighth percent change in the interest rate would have had
          an impact to interest expense of approximately $145,000 for the year
          ended December 31, 1996.
 
     (E)  Reflects the estimated income tax effects of the pro forma
          adjustments. No valuation allowance has been recognized related to the
          pro forma tax benefits based on FPA management's belief that it is
          more likely than not, based on the assessment of future taxable income
          and available tax planning strategies, that such benefit would be
          realized in future periods. If FPA had incurred the losses before
          income taxes of $153,549,841 for the year ended December 31, 1996
          included in the pro forma condensed consolidated statement of
          operations, FPA would need to generate a comparable amount of future
          taxable income over the next 15 years (this net operating loss
          carryforward period) in order to fully realize the benefit of these
          net operating losses.
 
     (F)  Reflects the effects of the assumed issuance of 5,227,273 shares of
          FPA Common Stock in exchange for 100% of the shares of outstanding HPI
          Voting Securities and HPI Options based on an assumed Adjusted FPA
          Value of $22 per share.
 
     (G)  The weighted average shares outstanding was calculated based on the
          historical weighted average shares outstanding of FPA giving effect to
          the assumed 5,227,273 shares of FPA Common Stock to be issued in
          connection with the Merger. In addition, for the year ended December
          31, 1996 the weighted average shares outstanding give effect to the
          4,076,087 shares of FPA Common Stock issued in connection with the
          FHMS acquisition and the 525,000 shares of FPA Common Stock issued in
          connection with the PFI acquisition.
 
                                       71
<PAGE>   76
 
     (H)  The HPI consolidated financial statements have been adjusted to
          conform with FPA's consolidation policies. Accordingly, certain
          professional corporations affiliated with HPI have not been
          consolidated due to HPI's lack of direct or indirect unilateral and
          perpetual control over the assets and operations of these professional
          corporations.
 
     (I)  Reflects the effect of the issuance of HPI Common Stock valued at an
          aggregate of $15,000,000 in connection with the Roll-up Transactions.
 
     (J)  Reflects the conversion of the HPI Preferred Stock into 8,000,025
          shares of HPI Common Stock.
 
     (K)  Reflects the amortization of goodwill incurred as a result of the
          Roll-up Transactions.
 
     (L)  Reflects the elimination of the minority interests share in net losses
          as a result of the Roll-up Transactions.

        MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
                          RESULTS OF OPERATIONS -- HPI
 
     The discussion and analysis set forth below is qualified in its entirety,
and should be read in conjunction with HPI's Consolidated Financial Statements
and notes thereto, and the other financial and business information related to
HPI included elsewhere in this Proxy Statement/Prospectus.
 
OVERVIEW
 
     HPI was incorporated and commenced operations in September 1993 and
completed its first affiliation with a physician group practice in November
1993. Through June 30, 1997, HPI has entered into administrative services
agreements with a total of eight physician group practices representing 150
physicians and six IPAs representing 1,572 physicians. As a result of HPI's
limited period of affiliation with the group practices and IPAs, as well as the
significant number of acquisitions made by HPI, HPI does not believe that the
period to period comparisons and percentage relationships within periods set
forth below are meaningful. The following table sets forth information regarding
HPI's physician group practice and IPA affiliations and capitated patients under
risk contracts as of April 1, 1997:

     HPI has affiliated with physician group practices and IPAs through
subsidiaries. When affiliating with a group practice or IPA, HPI has permitted
the physician-owners of the group practice or IPA to purchase shares of the
relevant HPI Subsidiary, which represents a minority interest in that HPI
Subsidiary. In connection with the minority interests, HPI has entered into
shareholders agreements with all minority shareholders which require that, at
the closing of the Merger, the holders of the minority interests exchange their
stock and options in HPI subsidiaries for HPI Common Stock with an equal value.
These exchanges are referred to in this Proxy Statement/Prospectus as the
"Roll-up Transactions." HPI and the holders of the minority interests have
initiated discussions required to reach agreement on valuation without the need
for a formal valuation. See "THE MERGER AGREEMENT -- Roll-up Transactions."
 
     HPI's revenue is derived from affiliated group practices which earn revenue
from providing medical services to enrollees of HMOs and Payors, on both a
capitated and fee-for-service basis, and from affiliations with IPAs, which earn
revenue by providing medical services to enrollees of HMOs and Payors on a
capitated basis. HPI, its affiliated group practices and its affiliated IPAs
contract directly with HMOs and managed care Payors for the provision of
specified medical services and to coordinate all inpatient and outpatient care
for the assigned enrollees. Generally, HPI or an affiliated group practice or
IPA receives a capitation payment from the Payor for members of the Payor who
selects one of the affiliated group practice's or IPA's primary care physicians
as the member's primary care provider. The capitation payment may be either a
fixed amount or a percentage of the premium related to the enrollee. In
addition, such contracts provide for the establishment of shared risk pools,
which represent an annual hospital budget fund against which all payments for
hospital services are credited. Under the Payor contracts, the networks are
entitled to receive a portion of any surplus remaining in the hospital funds at
the end of specified periods. Some of the Payor contracts obligate the networks
to bear a portion of any deficits in the hospital funds. Revenue earned by the
affiliated group practices and IPAs is reflected in the consolidated financial
statements of HPI by either the assignment of revenue under the operating
agreement or a security interest in accounts receivable, and the control by HPI
over the affiliated group practices or IPAs through the administrative service
agreements.
 
     The cost of medical services provided by the affiliated group practices,
IPAs and independent contracting physicians, includes payments to affiliated
primary care, specialty care and ancillary providers. Compensation for such
health care providers varies typically according to the type of provider.
Primary care physicians are compensated on a capitated basis, in which they
receive a fixed monthly fee for each enrollee selecting such physician, or on a
fee-for-service basis. Specialist and ancillary providers are typically
compensated on a fee-for-service basis. Hospitals are typically compensated on a
per diem basis.
 
     The nature of affiliated group practices affects the cost of affiliated
physician services, clinic salaries, wages and benefits, medical claims (if the
affiliated group practice has capitation arrangements), other clinic expenses
and depreciation and amortization. These expenses as a percentage of net
revenues will vary based upon the mix of primary care and specialist providers,
the percentage of net revenue received on a capitated basis and the scope of the
risk of providing health care services undertaken in a particular capitation
agreement.
 
     The nature of the IPAs affects the costs of medical claims, network
operating expenses and depreciation and amortization. These expenses as a
percentage of net revenues will vary based upon the scope of risk of providing
medical care undertaken in a specific capitation agreement and the underlying
variations in margin for commercial, Medicaid and Medicare contracts and the
growth in enrollment for these product lines.
 
     Net patient services revenue also includes fee-for-service revenue
generated by physicians employed by the affiliated group practices.
Fee-for-service revenue is reduced by provisions for contractual adjustments
which arise under the terms of certain reimbursement arrangements and managed
care contracts, and represent the difference between charges at the established
rates and estimated reimbursable amounts. Contractual adjustments are recognized
in the period services are rendered.
 
     Cost of affiliated physician services includes amounts paid to physicians
employed by the affiliated group practices under various compensation plans at
each professional corporation. The physician compensation plans are intended to
encourage clinical efficiency and productivity, and are based on factors such as
the
 
                                       76
<PAGE>   81
 
amount of prepaid revenue, the mix between primary care and specialty physicians
in the group and community standards for physician compensation.
 
     Clinic salaries, wages and benefits includes all amounts paid to
non-provider personnel employed at the affiliated group practices. The personnel
includes clinical, administrative and management personnel.
 
     Medical claims includes the cost of services rendered by network providers
as well as by non-network providers for which the affiliated group practices and
IPAs are financially responsible under capitated agreements. These amounts are
paid by either a subsidiary of HPI, the affiliated group practices, IPAs or the
Payor depending on the terms of the Payor contract. In certain contracts, funds
are advanced to an affiliated group practice or IPA which is responsible for the
payment of the claims. Under other contracts, the Payor pays the claims and
performs periodic settlements pursuant to which surpluses are paid to the
affiliated group practice or IPA or deficits are offset against future payments.
 
     Network operating expenses includes all the administrative costs, including
salaries, wages and benefits associated with subsidiaries who provide service to
IPAs.
 
     Other clinic expenses include all other operating expenses attributable to
affiliated group practices except for costs of affiliated physician services,
clinic salaries, wages and benefits, medical claims (if applicable), and
depreciation and amortization, interest income and expense and provision for
income taxes. These costs typically include occupancy costs, professional
liability insurance and medical and pharmaceutical supplies, among others.
 
     Minority interests represent the proportionate share of the net income or
loss of each subsidiary attributable to the minority shareholders of such
subsidiaries. If the equity in net losses exceeded the minority interests' share
in the equity, HPI recognized all losses in the consolidated statements of
operations.
 
     HPI's profitability depends upon effectively managing the cost and quality
of providing care in a prepaid environment, and enhancing the efficiency of
group practice and IPA operations.
 
     HPI's quarterly operating results are subject to fluctuations resulting
from the timing and amount of costs associated with HPI's development and
acquisition of group practices and IPAs, by trends in medical costs and by other
operational or external factors. Additionally, quarterly results may be affected
by significant differences between the actual and estimated amounts receivable
from or payable to Payors relating to capitation arrangements and incurred but
not reported medical claims. Such payables and receivables are settled
periodically, and the timing of the settlements vary by Payor and are governed
by the terms of the capitation agreement. In addition, changes in enrollment
from one Payor to another, particularly during the periods of open enrollment
for employer groups, could impact quarterly results.
 
RESULTS OF OPERATIONS
 
     THREE MONTHS ENDED MARCH 31, 1997 COMPARED TO THREE MONTHS ENDED MARCH 31,
1996.
 
     Net patient services revenues were $46.5 million for the three months ended
March 31, 1997 compared to $33.1 million for the three months ended March 31,
1996, an increase of $13.4 million, or 40%. This increase resulted from four new
affiliations with group practices which contributed revenues of $5.4 million and
the affiliation with an additional IPA which contributed revenues of $.6
million. Affiliation with group practices occurred in June, July, October and
November 1996 and affiliation with the IPA occurred in June 1996. Further, the
net revenue of HPI's existing affiliated group practices and IPAs in New York
increased by $10.0 million due to an increase in risk sharing percentages with
Oxford. This increase, which allowed HPI to recognize additional revenue, is
directly offset by an increase in medical claims expense.
 
     Cost of affiliated physician services were $5.1 million for the three
months ended March 31, 1997, compared to $3.9 million for the three months ended
March 31, 1996, an increase of $1.2 million, or 31%. This increase is primarily
attributable to four new affiliations with affiliated group practices. The
increase is not in proportion to the growth in revenue due to the increase in
revenue due to risk sharing increases in the Oxford contracts.
 
                                       77
<PAGE>   82
 
     For the three months ended March 31, 1997, medical claims were $29.9
million compared to $24.1 million for the three months ended March 31, 1996, an
increase of $5.8 million, or 24%. This increase is attributable to $10.0 million
of additional medical claims recognized due to an increase in the risk sharing
percentages with Oxford. This increase in medical claims is offset by a $4.7
million decrease resulting from the termination of an Oxford contract with an
IPA. Furthermore, increases in HPI's medical claims as the result of increases
in membership is offset by cost savings achieved through medical management
initiatives.
 
     For the three months ended March 31, 1997, other clinic expenses increased
$.7 million or 23% to $3.7 million from $3.0 million in 1996. This increase is
primarily attributable to the four new medical group affiliations.
 
     For the three months ended March 31, 1997, HPI's general corporate expenses
increased 36% to $1.5 million from $1.1 million for the same prior year period.
HPI continued to expand its corporate management and operations team and install
and operate its information systems.
 
     FISCAL 1996 COMPARED TO FISCAL 1995.
 
     For the year ended December 31, 1996, net patient services revenue
increased $52.6 million or 60% to $139.9 million from $87.3 million in 1995. The
increase resulted from four new affiliations with group practices which
contributed revenues of $5.9 million and an affiliation with an additional IPA
which contributed $.9 million. Affiliations with the group practices occurred in
June, July, October and November 1996 and affiliation with the IPA occurred in
June 1996. Full year results of the operations of an affiliated group practice
acquired in 1995 contributed an additional $6.8 million in revenue and an
affiliation with an additional IPA contributed an additional $15.3 million. The
remaining increase in net patient services revenue is attributable to increases
in enrollment of capitated membership, an increase in the number of primary care
physicians in the managed care network and an increase in fee-for-service
revenue.
 
     Cost of affiliated physician services increased $4.1 million or 33% to
$16.4 million from $12.3 million in 1995. The increase resulted from four new
affiliations with group practices which contribute $2.0 million and full year
results of the affiliated group practice acquired in 1995 contributed an
additional $2.1 million in 1996. This increase was offset by a $.4 million
decrease attributable to a reduction in the number of employed physicians at a
group practice. The growth in cost of affiliated physician services has not
increased in proportion to net patient services revenue since HPI has
experienced a higher level of revenue growth in capitation revenue for IPAs.
 
     Clinic salaries, wages and benefits increased to $14.0 million or 22% for
the year ended December 31, 1996 from $11.5 million in 1995. The increase is
primarily attributable to the four new affiliations with group practices which
contributed $1.5 million.
 
     Medical claims increased $40.8 million or 76% to $94.3 million for 1996
from $53.5 million in 1995. The increase is attributable to the full year
results of an IPA which affiliated with HPI in August 1995 which contributed
$17.0 million. The remaining increase is primarily attributable to an increase
in enrollment of capitated members in New York. Medical claims has increased
from 61% to 67% of net revenue due to the increase in HPI's IPA business.
 
     Other clinic expenses increased $3.6 million or 36% to $13.4 million for
1996 from $9.8 million in 1995. The increase is attributable to the new group
practice affiliations which contributed $1.3 million in 1996. Full year results
for the group practice acquired in 1995 contributed $2.1 million.
 
     For the year ended December 31, 1996, general corporate expenses were $5.0
million, an increase of $1.1 million or 27% from $3.9 million in 1995. HPI
continued to expand its management team and infrastructure to manage its
acquisitions and growth strategy. HPI expects general corporate expenses to
increase in gross dollars but not in proportion to growth in revenue and other
expenses.
 
     FISCAL 1995 COMPARED TO FISCAL 1994.
 
     For the year ended December 31, 1995, net patient services revenue
increased $67.1 million or 334% to $87.3 million from $20.2 million for 1994.
The increase resulted from HPI's affiliation with an additional
 
                                       78
<PAGE>   83
 
affiliated group practice in July 1995 and two additional IPAs in January and
August 1995, respectively, which produced approximately $32.7 million of
revenue. The full year results of the operations of the affiliated physician
group practices with which HPI affiliated in 1994 which produced approximately
$23.4 million of revenue, and increases in existing businesses. The increases in
revenue of HPI's affiliated group practices and IPAs resulted from increases in
enrollment of capitated membership and an increase in fee-for-service revenue.
The increase in fee-for-service revenue resulted from affiliation with an
additional affiliated group practice and an increase in the revenue generated by
physicians already employed by affiliated group practices.
 
     Cost of affiliated physician services increased to $12.3 million for the
year ended December 31, 1995 from $4.6 million for 1994. This increase is
attributable to affiliation with additional affiliated group practices in 1995,
which cost approximately $2.1 million and the full year results of affiliation
with additional affiliated group practices in 1994, which cost approximately
$5.1 million. Costs of physician services has decreased from 23% to 14% of net
revenues due to the increase in HPI's network business.
 
     Clinic salaries, wages and benefits increased $5.8 million or 100% to $11.5
million for the year ended December 31, 1995 from $5.7 million for 1994. The
increase is attributable to new affiliations with additional group practices and
the full year results for affiliation with additional group practices in 1994.
Clinic salaries, wages and benefits decreased as a percentage of revenue due to
the addition of IPAs, which do not require clinical staffing
 
     Medical claims for the year ended December 31, 1995 increased to $53.5
million from $5.1 million for 1994. The increase in medical claims is due
primarily to HPI's affiliation with additional IPAs in January and August 1995.
The increase is also attributable to growth after HPI's affiliation with these
additional IPAs as physicians were added and covered lives increased for
existing physicians.
 
     General corporate expenses increased in gross dollars as HPI has continued
to expand its management team, corporate office and install and operate its
information systems. HPI expects general corporate expenses to increase in the
future in gross dollars. However, the expense should decline as a percentage of
revenue.
 
LIQUIDITY AND CAPITAL RESOURCES
 
     HPI requires capital primarily to acquire the assets of group practices,
develop managed care networks around its affiliated group practices, develop
affiliations with new IPAs and expand the managed care contracting network of
its affiliated IPAs. To fund this development and growth, HPI has sold HPI
Preferred Stock to Oxford and WellPoint pursuant to the 1994 Securities'
Purchase Agreement. As of March 31, 1997, Oxford and WellPoint had purchased an
aggregate of $50 million of HPI Preferred Stock.
 
     Cash was $11.0 million at March 31, 1997, compared to $9.3 million at
December 31, 1996. At March 31, 1997, HPI had a working capital deficit of $.3
million, compared to a deficit of $1.8 million at December 31, 1996. Cash used
in operating activities was $.1 million, $.8 million, $4.9 million, and $4.5
million for the three months ended March 31, 1997 and the years ended December
31, 1996, 1995 and 1994, respectively. The operating deficits are attributable
to general corporate expenses required to generate growth for HPI into
additional markets and to fund operating resources required to increase the
operational effectiveness of the managed care networks. HPI has no planned
material capital expenditures or capital commitments.
 
     HPI expects that its existing cash resources and anticipated cash flow from
operations will not be sufficient to meet HPI's anticipated acquisition,
expansion, and working capital needs for the next 12 months. If HPI is unable to
consummate the Merger and is unable to increase its cash flow from operations,
HPI will be required to explore other financing alternatives. These alternatives
will include a potential offering of HPI Common Stock, the issuance of long-term
or short-term indebtedness or the issuance of its securities in a private
transaction. No assurances can be made that such financings will be available to
HPI on satisfactory terms and conditions.

                                BUSINESS OF HPI
 
     HPI is a PPM which invests in and manages multi-specialty physician medical
groups and IPAs. HPI or its affiliated medical group or IPA, contracts with HMOs
and other Payors on a capitated or global fee basis in selected metropolitan
markets. HPI's strategy is to affiliate with physicians who are seeking a
partner to assist the medical group or network in transitioning from a
fee-for-service oriented health care system to a managed care system. In each
market, HPI seeks to affiliate with a locally prominent medical group or IPA and
assist the medical group or IPA in building a managed care infrastructure and
developing a high quality, geographically strong network of physicians. The
network is designed to increase the number of available primary care physicians,
which provides an opportunity for HPI to increase the number of patients served
under a capitated or global fee contract. HPI believes this approach enables
physicians to provide high quality, cost-effective health care, is highly
desirable to both Payors and patients and is more likely to assist physicians in
successfully adapting to a managed care environment. HPI has targeted major
metropolitan markets with lower HMO penetration. HPI should benefit as managed
health care grows in these geographic markets by an increase in new Payor and
physician relationships.
 
     The key elements of HPI's strategy are as follows:
 
          Focus on High Quality Physician Group Practices. HPI develops managed
     care networks in local communities by affiliating with high quality and
     locally prominent physician groups. These physicians are often community
     leaders, are sought after by both Payors and patients, and are likely to
     better lead and adapt to a managed care system that requires significantly
     more efficient delivery of health care resources. In such affiliations, HPI
     purchases substantially all of the practices' operating assets and enters
     into long-term administrative services agreements, which align the
     incentives of HPI and the physicians to provide high quality efficient
     care. HPI's affiliation with these physician group practices and IPAs
     serves as the hub for the development of managed care networks.
 
          Develop Primary Care-Oriented Networks. HPI develops primary
     care-oriented multispecialty physician networks which deliver high quality,
     low cost health care to patients and HMOs. Primary care physicians, as the
     "gatekeepers" of the managed care system, control patient access to
     specialist, hospital and other services. By controlling patient access,
     primary care physicians can exert significant control over the quality and
     price of specialist and hospital services, which control often exceeds that
     of Payors. Furthermore, this control is enhanced through the addition of
     primary care physicians, which has the capability of increasing the number
     of covered members in the managed care network.
 
          Manage the Delivery of Quality Medical Care. HPI seeks to enhance the
     ability of its affiliated physicians to provide efficient, high quality
     care to their patients. HPI empowers its affiliated physicians to develop
     and lead the implementation of quality and utilization management programs.
     By placing physicians in the decision making and oversight roles, HPI
     believes it can generate greater physician enthusiasm and patient
     satisfaction in the managed care environment and achieve superior quality
     and cost of care results.
 
          Develop Sophisticated Information Systems. Sophisticated information
     technology is critical for HPI and its affiliated physicians to manage the
     financial and clinical risk of its capitation arrangements. HPI's
     information system is a comprehensive system which administers patient
     eligibility and benefits, claims payment, physician referrals, case
     management and data management. The system enables HPI to administer
     physician-designed quality and utilization management programs, pay for
     specialist services at rates below HMO fees, and analyze financial and
     clinical data.

          Negotiate Capitated Arrangements with Payors. HPI has negotiated
     multiple shared and full risk contracts with Payors. Such arrangements give
     HPI and its affiliated physicians incentives to deliver high quality, cost
     effective services to their patients. HPI believes that the marketplace for
     such services is increasing.
 
          Target Local Communities in Major Metropolitan Areas. HPI has targeted
     local communities in major metropolitan areas for its development areas.
     Large markets offer significant growth opportunities that can leverage
     existing management and physician infrastructure. A concentrated community
     presence increases both the attractiveness of HPI's managed care networks
     and its ability to negotiate favorable rates and contract terms with Payors
     and other providers. In addition, many metropolitan markets have a
     substantial oversupply of specialist physicians and hospital beds, which
     provide HPI the opportunity to obtain significant contractual discounts on
     specialist and hospital services.

                          INDEPENDENT AUDITORS' REPORT
 
To the Stockholders and Board of Directors of
Health Partners, Inc.:
 
     We have audited the accompanying consolidated statements of financial
position of Health Partners, Inc. and Subsidiaries as of December 31, 1994, 1995
and 1996 and the related consolidated statements of operations, changes in
stockholders' equity, and cash flows for each of the years in the three-year
period ended December 31, 1996. These consolidated 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 audits.
 
     We conducted our audits 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 audits provide a reasonable basis for our opinion.
 
     In our opinion, the consolidated financial statements referred to above
present fairly, in all material respects, the financial position of Health
Partners, Inc. and Subsidiaries as of December 31, 1994, 1995 and 1996 and the
results of their operations and their cash flows for each of the years in the
three-year period ended December 31, 1996 in conformity with generally accepted
accounting principles.

                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS
                        DECEMBER 31, 1994, 1995 AND 1996
 
 (1) ORGANIZATION AND OPERATION
 
     Health Partners, Inc. ("HPI" or the "Company") was incorporated and
commenced operations on September 15, 1993. HPI, through its majority owned
subsidiaries, provides management systems and services, non-physician health
care personnel and equipment to affiliated medical corporations, independent
practice associations ("IPAs") and managed care contracting networks. HPI
operates primarily in the managed health care business and supports health care
networks of multi-specialty physicians, through which managed health care is
provided under contracts with prepaid health plans. Affiliated medical
corporations, IPAs and managed care contracting networks employ physicians,
contract with physicians and professional medical corporations, and/or contract
with health maintenance organizations ("HMOs"). All transactions and account
balances of the affiliated medical corporations, IPAs and managed care
contracting networks are reflected in the consolidated financial statements of
HPI by either the assignment of revenue under the operating agreements (See Note
2 -- Revenue and Cost Recognition) or a security interest in the accounts
receivable, and the control maintained by the Company over the affiliated
medical corporations, IPAs or managed care contracting networks. The Company
believes it has control over the assets and operations of the affiliated medical
corporations, IPAs and managed care contracting networks exclusive of medical
decisions, and notwithstanding the lack of technical majority ownership of the
stock of such entities, consolidation of the affiliated medical corporations is
necessary to present fairly the financial position and results of operations of
the Company. Control by the Company is demonstrated by (i) the length of the
original terms of the administrative services agreements, (ii) the successive
extension periods provided by the administrative services agreements, (iii) the
continuing investment of capital by the Company, (iv) the employment of the
majority of the non-physician personnel and (v) the nature of the services
provided to the affiliated medical corporations, IPA's and managed care
contracting networks by the Company.
 
 (2) SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES
 
  Principles of Consolidation
 
     The accompanying consolidated financial statements include the accounts of
HPI and its majority owned subsidiaries and its affiliated medical corporations,
IPAs and managed care contracting networks. Significant intercompany accounts
and transactions have been eliminated in consolidation.
 
  Minority Interests
 
     Minority interests represent the minority stockholders' proportionate share
of the equity of subsidiaries. Brooklyn Health Partners, Inc. ("BHPI"), Gotham
Practice Management, Inc. ("GPMI"), Network Management Strategies Corporation
("NMS"), San Antonio Health Partners, Inc. ("SAHPI") and Comprehensive Primary
Care MSO, Inc. ("CPC") have incurred net losses which exceed the minority
interests' share of equity. To the extent the net losses exceed the equity of
the minority interests, the Company recognizes all losses in the consolidated
statements of operations. As these subsidiaries generate net income, the Company
will recognize all net income until such losses have been fully offset. At
December 31, 1994, 1995 and 1996, cumulative net losses of minority interests
recognized by the Company were approximately $491,000, $1,033,000, and
$1,551,000, respectively.
 
  Revenue and Cost Recognition
 
     Operating revenue consists of capitation revenue (including shared-risk
revenue) and fee-for-service revenue. Revenue is recognized on an accrual basis
based upon the management agreement with the affiliated medical corporations.
Revenue earned by the affiliated medical corporations and IPAs is reflected in
the consolidated financial statements of the Company by either the assignment of
revenue under the operating agreement or a security interest in the accounts
receivable, and the control by the Company over the affiliated
 
                                       F-7

                     HEALTH PARTNERS, INC. AND SUBSIDIARIES
 
             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                        DECEMBER 31, 1994, 1995 AND 1996
 
medical corporations, IPAs or managed care contracting networks. The Company
recognizes capitation revenue from HMOs contracting with affiliated medical
corporations and independent practice associations for the delivery of health
care services. Amounts due to affiliated medical corporations, independent
practice associations and other health care providers for the provision of
health care services in connection with HMO contracts are accrued as incurred.
The HMO contracts contain shared-risk provisions whereby additional incentive
revenue can be earned or penalties can be incurred based upon the utilization of
inpatient services by assigned HMO enrollees. The Company records estimated
shared-risk amounts receivable from (or payable to) HMOs based upon inpatient
utilization and associated costs incurred by assigned HMO enrollees compared to
budgeted costs. Differences between actual contract settlements and amounts
estimated as receivable (or payable) relating to HMO shared-risk arrangements
are recorded in the year of final settlement. Management believes that accrued
medical costs, which represent the amounts payable for services incurred by
patients but not yet paid at December 31, 1994, 1995 and 1996, is adequate to
cover claims that will ultimately be paid.
 
  Contractual Adjustments
 
     Contractual adjustments arise due to the terms of certain reimbursement
arrangements and managed care contracts. These adjustments represent the
difference between charges at established rates and estimated reimbursable
amounts and are recognized in the period the services are rendered. Any
differences between the estimated reimbursable amounts and actual payments under
reimbursement arrangements are reported in the year the payments are received.
 
  Property, Equipment and Leasehold Improvements
 
     Property, equipment and leasehold improvements are stated at cost.
Depreciation is computed using the straightline method over the estimated useful
lives of the assets. The principal estimated useful lives are 5 years for
medical, computer and office equipment and 30 years for buildings. Leasehold
improvements are amortized over the estimated useful lives of the improvements
or the terms of the leases, whichever is shorter. The principal estimated useful
life is 10 years.
 
     Upon retirement or sale, the cost and related accumulated depreciation are
removed from the accounts and any resultant gains or losses are included in the
consolidated statements of operations.
 
  Intangible Assets
 
     Intangible assets resulting from business acquisitions principally consist
of the excess of the acquisition cost over the fair value of the net assets
acquired ("goodwill"). Goodwill is amortized on a straight-line basis over 20 to
30 years based upon its estimated useful life.
 
     Other intangible assets are amortized on a straight-line basis over their
estimated useful lives.
 
     During 1995, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards (SFAS) No. 121, "Accounting for the Impairment of
Long-Lived Assets and for Long-Lived Assets to be Disposed of" ("SFAS No. 121").
SFAS No. 121 establishes accounting standards for the impairment of long-lived
assets, certain identifiable intangibles, and goodwill related to those assets
to be held and used and for long-lived assets and certain identifiable
intangibles to be disposed of. If events and circumstances occur which indicate
impairment, SFAS No. 121 requires that impairment losses be recognized based on
the difference between the fair value and carrying value of the assets.
Long-lived assets to be disposed of should be reported at the lower of carrying
amount or fair value less cost to sell. SFAS No. 121 is effective for financial
statements issued for fiscal years beginning after December 15, 1995. The
Company has

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                        DECEMBER 31, 1994, 1995 AND 1996
 
complied with the provisions of SFAS No. 121. The adoption of SFAS No. 121 did
not have a material effect on the accompanying consolidated financial
statements.
 
     Accumulated amortization of intangible assets resulting from business
acquisitions was approximately $1,916,000, $2,335,000 and $2,991,000 as of
December 31, 1994, 1995 and 1996, respectively.
 
  Income Taxes
 
     The Company follows Financial Accounting Standards Board Statement of
Financial Accounting Standards No. 109, "Accounting for Income Taxes" ("SFAS No.
109"). SFAS No. 109 requires accounting for income taxes on an asset and
liability method. Under the asset and liability method of SFAS No. 109, deferred
tax assets and liabilities are recognized for the consequences attributable to
differences between the financial statement carrying amount of existing assets
and liabilities and respective tax bases. Under this method, deferred tax
liabilities and assets are measured using enacted tax rates expected to apply to
taxable income in the years in which those temporary differences are expected to
be recovered or settled. Under SFAS No. 109, the effect on deferred tax assets
and liabilities of a change in tax rates is recognized in income in the period
that includes the enactment date. Certain entities file tax returns on a stand
alone basis.
 
  Accounting for Stock-Based Compensation
 
In October 1995, the Financial Accounting Standards Board issued SFAS Statement
No. 123, "Accounting for StockBased Compensation" ("SFAS No. 123") which is
effective for financial statements for fiscal years beginning after December 15,
1995. As permitted under SFAS No. 123, the Company has elected not to adopt the
fair value based method of accounting for its stock-based compensation plans,
but has complied with the disclosure requirements of SFAS No. 123 (note 10) and
will continue to account for such compensation under the provisions of
Accounting Principles Board Opinion No. 25 "Accounting for Stock Issued to
Employees".
 
  Cash and Cash Equivalents
 
     HPI considers all highly liquid investments with an original maturity of
three months or less to be cash equivalents. A substantial portion of HPI's cash
and cash equivalents is deposited in three banks. HPI monitors each bank's
financial status and does not believe the deposits are subject to a significant
degree of risk.
 
  Disclosures about the Fair Value of Financial Instruments
 
     The Company values its financial instruments as required by SFAS Statement
No. 107, "Disclosures about Fair Values of Financial Instruments." The carrying
amounts of cash and cash equivalents, accounts receivable, accounts payable,
short-term debt and long-term variable-rate debt approximate fair value.
 
  Management's 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 at the dates of the financial
statements and the reported amounts of revenues and expenses during the
reporting periods. Actual results could differ from those estimates.
 
  Reclassifications
 
     Certain prior year amounts have been reclassified to conform with the 1996
presentation.

 (3) ACQUISITIONS
 
     During 1994, 1995 and 1996 the Company acquired the medical organizations
described below and accounted for the transactions in accordance with the
purchase method of accounting. The results of operations of the acquired
companies are included in the Company's consolidated statements of operations
for the periods in which they were owned by the Company. The acquisitions are
generally financed through various combinations of cash payments, notes payable
and the assumption of certain liabilities. Simultaneous with its acquisitions,
the Company's majority owned subsidiaries enter into an administrative services
agreement ("ASA") with affiliated medical corporations and/or IPAs. After an
initial term, the ASAs relative to the medical organizations have automatic
long-term renewal options, except for SAHPI which has a forty year ASA and
Gateway Physician Services, L.P. ("GPS") which has an indefinite term, and can
only be terminated if the subsidiaries breach the ASA or at the option of the
subsidiary.
 
     In August 1994, the Company acquired a majority interest in VMA, Inc. for
an aggregate purchase price of approximately $5,250,000. The stock of VMA, Inc.
was transferred by the Company to Gateway Physician Services, L.P. for an equal
ownership interest in GPS. The minority shareholders also exchanged their
ownership interests in VMA, Inc. for an equivalent ownership interest in GPS.
Simultaneous with the transaction, GPS entered into non-compete agreements with
certain physicians.
 
     In October 1994, GPMI acquired the property, medical equipment and office
equipment of Gotham Practice Management Services, Inc. for approximately
$700,000.

$2,475,000.
 
     In October 1996, CHPI acquired the property, medical and office equipment
of Primary Care Associates of Northern Kentucky, P.S.C. and entered into
non-compete agreements for an aggregate purchase price of $3,275,000.
 
     In November 1996, CPC acquired the property, medical and office equipment

 (6) CREDIT FACILITIES
 
     In October 1994, GPS executed a credit agreement with a bank that provided
a line of credit (the "line") of $800,000 and an equipment loan with maximum
permitted borrowing of $600,000 ("equipment loan"). The agreement required GPS
to meet both financial and non-financial covenants and contained covenants
restricting the payment of dividends, incurrence of debt and sale of assets. As
of December 31, 1994, GPS had no borrowings under this agreement.
 
     In September 1995, GPS converted outstanding borrowings under its equipment
loan into a term note. The principal balance of approximately $315,000 bears
interest at 8.9% and is payable over five years.

                        DECEMBER 31, 1994, 1995 AND 1996
 
     In October 1995, GPS amended its credit agreement with a bank to provide a
$1,500,000 line of credit and increase the equipment loan to $500,000. GPS's
requirement to meet both financial and non-financial covenants remained
unchanged.
 
     In May 1996, GPS amended its credit agreement with a bank regarding its
existing line of credit and equipment loan. The line, which provided for
borrowing based upon 80% of eligible accounts receivable, as defined, was
terminated in August 1996. The principal balance was repaid in two installments
in July and August 1996. The equipment loan, which was based on 90% of the
purchased equipment's value and bore interest at the bank's prime rate plus a
spread based on GPS's financial ratios, was terminated in May 1996. Effective
with this amendment, GPS maintained its existing deed of trust note, term note
and the covenants contained in GPS's prior agreement with the bank.
 
     As of December 31, 1996, GPS was in default on both financial and
non-financial covenants. GPS is in discussions with the bank regarding curing
the default.
 
     Borrowings under the line are collateralized by the accounts receivable,
and borrowings under the equipment loan are collateralized by the underlying
equipment. Also, the bank maintains an additional security interest in all
current and future assets of GPS and is superior to all current and future
indebtedness of GPS.
 
     The following schedule summarizes the activity with respect to the credit
agreements and term note:

     In December 1996, HVHPI entered into a $250,000 line of credit agreement
with a bank. The line of credit bears interest at the bank's prime rate plus
 1/2 percentage point, is collateralized by HVHPI's accounts receivable and
expires on December 10, 1997. At December 31, 1996, there were no borrowings
under this agreement.
 
     See Note 7, Long-Term Debt and Notes Payable, for information regarding the
deed of trust note.
 
 (7) LONG-TERM DEBT AND NOTES PAYABLE
 
     In December 1994, GPS executed a $738,000 deed of trust note ("the note")
collateralized by GPS's building. Payment of the note is based on a 15 year
payment schedule with a five year balloon payment and bears a fixed rate of
interest at 10.35%. GPS is subject to the same financial, non-financial and
restrictive covenants as in its credit facilities (See Note 6 -- Credit
Facilities). The balance of the note was $738,000, $720,000 and $697,000 as of
December 31, 1994, 1995 and 1996, respectively.
 
     In conjunction with the acquisition of VMA, Inc., the Company agreed to a
deferred purchase price of $1,750,000 payable over 3 years beginning in 1996. In
1996 the deferred purchase price was renegotiated to $1,450,000.
 
     Obligations under capital leases at December 31, 1996 totaled $315,000 of
which $87,000 was current.

             NOTES TO CONSOLIDATED FINANCIAL STATEMENTS (CONTINUED)
                        DECEMBER 31, 1994, 1995 AND 1996
 
 (9) STOCKHOLDERS' EQUITY
 
     In May 1994, the Company underwent a capital restructuring whereby the
Articles of Incorporation were amended to redefine the Company's Series A
preferred stock and establish a Series B preferred stock. The capital
restructuring eliminated the redemption feature of the Old-Series A preferred
stock and added a conversion feature, at the holder's option or under certain
circumstances as defined below, to the Company's common stock based upon a
predetermined conversion price.
 
     The preferred stock is subject to a mandatory conversion if the Company
consummates a public offering of its common stock in excess of stated levels.
Also, the preferred stock has a liquidation preference equal to the original
issuance price, accrued dividends and declared but unpaid dividends. The Series
B preferred stock maintains the same provisions as the New-Series A preferred
stock except for the conversion price.
 
     In May 1994, Oxford Health Plans, Inc. ("Oxford"), a minority shareholder,
purchased all outstanding Old-Series A preferred stock for stated value. Oxford
then exchanged the Old-Series A preferred stock for Series B preferred stock and
payment of cumulative unpaid dividends, which approximated $52,000, on Oxford's
Old-Series A preferred stock.
 
     In conjunction with the restructuring, the Company purchased 4,200,000
shares of its common stock for $4,200 and declared and paid a stock dividend,
which amounted to 675,000 shares. Subsequent to the dividend, the Company issued

              NOTES TO UNAUDITED CONSOLIDATED FINANCIAL STATEMENTS
                                 MARCH 31, 1997
 
(1) SUBSEQUENT EVENTS
 
     The Company has entered into an Agreement and Plan of Merger dated as of
July 1, 1997 with FPA Medical Management, Inc. ("FPA") whereby the Company will
become a wholly owned subsidiary of FPA and all outstanding securities of the
Company will be exchanged for FPA common stock. The total merger consideration
to be received will be subject to adjustment depending upon the average closing
stock price of FPA as reported on the Nasdaq for the ten consecutive trading
days ending on the date that is two trading days prior to the closing of the
transaction. All outstanding options at the time of the merger will be cancelled
in exchange for a number of shares of fully paid FPA common stock. The FPA
common stock will have a market value equal to the fair value of such option by
applying a variation of the Black-Scholes option pricing model by an investment
banking firm.
 
     In connection with the aforementioned transaction, WellPoint and Oxford
have agreed to convert the Series A Convertible Preferred Stock and Series B
Convertible Preferred Stock, respectively, into 3,299,982 and 4,700,043 shares
of Company common stock, respectively.
 
     As the result of the Merger, the Company has exercised its right to
exchange the minority stockholders' share of the equity of the Company's
subsidiaries for the Company's common stock. The Company has entered into
negotiations with the minority stockholders in order to reach an agreement as to
the fair value of the subsidiaries as prescribed in the shareholders' agreements
with the minority stockholders.

SECTION 2.3  Directors and Executive Officers of the Surviving Corporation.
 
     The directors of the Surviving Corporation shall be the directors of
Acquisition serving immediately prior to the Effective Time and the executive

SECTION 2.4  Effects of Merger.
 
     The Merger shall have the effects set forth in Section 259 of the DGCL.
 
                                  ARTICLE III
 
                              CONVERSION OF SHARES
 
SECTION 3.1  Conversion of Shares in the Merger.
 
     (a) Company Common Stock. At the Effective Time, by virtue of the Merger
and without any action on the part of the holder thereof, each issued and
outstanding share of Company Common Stock, par value $.001 per share (the
"Company Common Stock"), other than shares to be canceled in accordance with
Section 3.1(c) hereof and other than Dissenting Shares (as defined in Section
3.1(d) hereof), shall be converted into the right to receive the number of
shares of fully paid and nonassessable common stock, par value $.002 per share,
of Parent ("Parent Common Stock") determined by dividing the "Numerator" by the
"Denominator" (the quotient herein referred to as the "Exchange Ratio"). The
Denominator shall be the maximum number of shares of Company Common Stock issued
and outstanding at the Effective Time plus shares of Company Common Stock
issuable pursuant to Section 7.14 hereof. The Numerator shall be the remainder
which results when (y) the Stock Option Shares is subtracted from (z) the
quotient which results when $115,000,000 is divided by the Effective Valuation
Amount. The Effective Valuation Amount shall be:
 
          (i) the average of the closing prices of Parent Common Stock as
     reported on the Nasdaq National Market ("NNM") for the ten (10) consecutive
     trading days ending on the date that is two (2) trading days prior to the
     Closing Date (as defined in Section 3.6) (the "Parent Value") if such
     average is greater than or equal to $18.00 but less than or equal to
     $22.00; or
 
          (ii) $18.00, if the Parent Value is less than $18.00; or
 
          (iii) $22.00, if the Parent Value is greater than $22.00.
 
The Stock Option Shares shall equal the number of shares of Parent Common Stock
issuable pursuant to Section 3.5 hereof in respect of Company Stock Options (as
defined in Section 3.5 hereof) outstanding on the Closing Date whether or not
the same are vested immediately after giving effect to the Merger.
 
     The Company shall provide to Parent, no later than the date on which the
Parent Value is determinable pursuant to this Section 3.1, a certificate (the
"Denominator Certificate") reasonably acceptable to Parent setting forth the
Denominator and the method used in the calculation thereof. If, prior to the
Effective Time, the announcement of a transaction by the Parent requires the
amendment or re-filing of the Registration Statement (as defined in Section
4.8), and, as a result of the re-filing or amendment of the Registration
Statement, the Closing occurs more than 90 days after the date of this
Agreement, notwithstanding clause (ii) of the definition of Effective Valuation
Amount, the Effective Valuation Amount shall equal the Parent Value if the
Parent Value is less than $18.00. Except as set forth in the immediately
preceding sentence, in no event will the number of shares of Parent Common Stock
issued upon the Merger (including shares issued under Section 3.5 hereof) exceed
6,388,889 shares.
 
     (b) Company Preferred Stock. The Company shall use its reasonable best
efforts to cause, immediately prior to the Effective Time, each issued and
outstanding share of the Company's Series A Convertible Preferred Stock, par
value $.001 per share, and Series B Convertible Preferred Stock, par value $.001
per
 
                                       A-2
<PAGE>   118
 
share (collectively, the "Company Preferred Stock") to be converted into shares
of Company Common Stock, in accordance with the provisions of the relevant
Certificate of Designations for such Company Preferred Stock. At the Effective
Time, by virtue of the Merger and without any action on the part of the holder
thereof, such shares of Common Stock, other than shares to be canceled in
accordance with Section 3.1(c) hereof and other than Dissenting Shares, shall be
converted into the right to receive a number of shares of fully paid and
nonassessable shares of Parent Common Stock based on the Exchange Ratio.
 
     (c) Cancellation of Company Stock. All shares of Company Common Stock and
Company Preferred Stock (collectively, "Company Stock") which, immediately prior
to the Effective Time, are held by the Company in its treasury shall be canceled
and extinguished and shall cease to exist and no consideration shall be
delivered with respect thereto.
 
     (d) Dissenting Shares. (i) If applicable, notwithstanding any provision of
this Agreement to the contrary, each outstanding share of Company Stock, the
holder of which (x) has not voted in favor of the Merger, (y) has perfected such
holder's right to an appraisal of such holder's shares in accordance with the
applicable provisions of the DGCL and (z) has not effectively withdrawn or lost
such right to appraisal (a "Dissenting Share"), shall not be converted into or
represent a right to receive shares of Parent Common Stock pursuant to Section
3.1(a) or 3.1(b), as applicable, but the holder thereof shall be entitled only
to such rights as are granted by the applicable provisions of the DGCL;
provided, however, that any Dissenting Share held by a person at the Effective
Time who shall, after the Effective Time, withdraw the demand for appraisal or
lose the right of appraisal, in either case pursuant to the DGCL, shall be
deemed to be converted into, as of the Effective Time, the right to receive
Parent Common Stock pursuant to Section 3.1(a) or 3.1(b), as applicable.
 
     (ii) The Company shall give Parent prompt notice of any written demands for
appraisal, withdrawals of demands for appraisal and any other instruments served
pursuant to the applicable provisions of the DGCL relating to the appraisal
process received by the Company and shall allow Parent the right to direct any
proceedings and the resolution thereof relating to such process.
 
     (e) Acquisition Shares. Each share of capital stock of Acquisition issued
and outstanding immediately prior to the Effective Time shall be converted into
and exchanged for one validly issued, fully paid and nonassessable share of
common stock of the Surviving Corporation.
 
SECTION 3.2  Equitable Adjustment.
 
     The calculations set forth in Section 3.1 hereof shall be subject to
equitable adjustment in the event of, or the setting of a record date prior to
the Effective Time with respect to, any stock split, stock dividend, reverse
stock split, recapitalization, reclassification or combination of Company Stock
or Parent Common Stock or dividend or distribution with respect to Parent Common
Stock or Company Stock or other change in the number of shares of Company Stock
outstanding prior to the Closing (as defined in Section 3.6 hereof) other than
issuances of shares pursuant to the exercise of outstanding stock options and
issuance of shares pursuant to the transactions contemplated by Section 7.14
hereof.
 
SECTION 3.3  Exchange of Certificates.
 
     (a) From and after the Effective Time, each holder of an outstanding
certificate which immediately prior to the Effective Time represented shares of
Company Stock shall be entitled to receive in exchange therefor, upon surrender
thereof to a bank or trust company designated before the Effective Time by
Parent and reasonably acceptable to the Company (the "Exchange Agent"), a
certificate or certificates representing the number of whole shares of Parent
Common Stock to which such holder is entitled pursuant to Section 3.1 hereof.
Notwithstanding any other provision of this Agreement, (i) until holders or
transferees of certificates theretofore representing shares of Company Stock
have surrendered them for exchange as provided herein, no dividends shall be
paid with respect to any shares represented by such certificates and no payment
for fractional shares shall be made and (ii) without regard to when such
certificates representing shares of Company Stock are surrendered for exchange
as provided herein, no interest shall be paid on any dividends or
 
                                       A-3
<PAGE>   119
 
any payment for fractional shares. Upon surrender of a certificate which
immediately prior to the Effective Time represented shares of Company Stock,
there shall be paid to the holder of such certificate the amount of any
dividends which theretofore became payable, but which were not paid by reason of
the foregoing, with respect to the number of whole shares of Parent Common Stock
represented by the certificate or certificates issued upon such surrender.
 
     (b) If any certificate for shares of Parent Common Stock is to be issued in
a name other than that in which the certificate for shares of Company Stock
surrendered in exchange therefor is registered, it shall be a condition of such
exchange that the person requesting such exchange shall pay any applicable
transfer or other taxes required by reason of such issuance.
 
     (c) Promptly after the Effective Time, Parent shall make available to the
Exchange Agent the certificates representing shares of Parent Common Stock
required to effect the exchanges referred to in paragraph (a) above and cash for
payment of any fractional shares referred to in Section 3.4 hereof.
 
     (d) Promptly after the Effective Time, the Exchange Agent shall mail to
each holder of record of a certificate or certificates that immediately prior to
the Effective Time represented outstanding shares of Company Stock (the "Company
Certificates") (i) a letter of transmittal (which shall specify that delivery
shall be effected, and risk of loss and title to the Company Certificates shall
pass, only upon actual delivery of the Company Certificates to the Exchange
Agent) and (ii) instructions for use in effecting the surrender of the Company
Certificates in exchange for certificates representing shares of Parent Common
Stock. Upon surrender of Company Certificates for cancellation to the Exchange
Agent, together with a duly executed letter of transmittal and such other
documents as the Exchange Agent shall reasonably require, the holder of such
Company Certificates shall be entitled to receive in exchange therefor a
certificate representing that number of whole shares of Parent Common Stock into
which the shares of Company Stock theretofore represented by the Company
Certificates so surrendered shall have been converted pursuant to the provisions
of Section 3.1 hereof, and the Company Certificates so surrendered shall be
canceled.
 
     (e) Promptly following the date which is nine (9) months after the
Effective Time, the Exchange Agent shall deliver to Parent all cash,
certificates (including any Parent Common Stock) and other documents in its
possession relating to the transactions described in this Agreement, and the
Exchange Agent's duties shall terminate. Thereafter, each holder of a Company
Certificate may surrender such Company Certificate to the Surviving Corporation
and (subject to applicable abandoned property, escheat and similar laws) receive
in exchange therefor the Parent Common Stock, without any interest thereon. If
any certificate or certificates that immediately prior to the Effective Time
represented outstanding shares of Company Stock entitled to payment pursuant to
Section 3.1 hereof shall not have been surrendered for such payment prior to
such date on which any payment in respect thereof would otherwise escheat to or
become property of any governmental agency or other governmental entity, such
shares of Company Stock shall, to the extent permitted by applicable law, be
deemed to be canceled and no money or other payment will be due to the holder
thereof.
 
     (f) In the event any Company Certificate shall have been lost, stolen or
destroyed, upon the making of an affidavit of that fact by the person claiming
such Company Certificate to be lost, stolen or destroyed, Parent shall issue in
exchange for such lost, stolen or destroyed Company Certificate the Parent
Common Stock deliverable in respect thereof determined in accordance with
Section 3.1 hereof. When authorizing such payment in exchange therefor, the
board of directors of Parent may, in its discretion and as a condition precedent
to the issuance thereof, require the owner of such lost, stolen or destroyed
Company Certificate to give the Surviving Corporation such indemnity as it may
reasonably direct as protection against any claim that may be made against the
Surviving Corporation with respect to the Company Certificate alleged to have
been lost, stolen or destroyed.
 
SECTION 3.4  No Fractional Securities.
 
     Notwithstanding any other provision of this Agreement, no certificates or
scrip for fractional shares of Parent Common Stock shall be issued in the Merger
and no Parent Common Stock dividend, stock split or interest shall relate to any
fractional security, and such fractional interests shall not entitle the owner
thereof to vote or to any other rights of a security holder. In lieu of any such
fractional shares, each holder of Company
 
                                       A-4
<PAGE>   120
 
Stock who would otherwise have been entitled to receive a fraction of a share of
Parent Common Stock (in the aggregate) upon surrender of Company Certificates
for exchange pursuant to Section 3.3 hereof shall be entitled to receive from
the Exchange Agent a cash payment equal to such fraction multiplied by the
Parent Value.
 
SECTION 3.5  Options to Purchase Company Stock.
 
     (a) Each option to purchase shares of Company Common Stock (a "Company
Stock Option") which is outstanding immediately prior to the Effective Time
pursuant to any stock option plan of the Company in effect on the date hereof
(the "Company Stock Plans") shall be canceled at the Effective Time and the
holder of such Company Stock Option shall be entitled to receive a number of
shares of Parent Common Stock, decreased to the nearest whole share, equal to
the quotient which results when the "Fair Market Value" of such Company Stock
Option at the Effective Time is divided by the Parent Value. The Fair Market
Value of all Company Stock Options shall be the fair value thereof determined by
an investment banking firm selected by the Company that is acceptable to the
Parent based upon the Effective Valuation Amount and the Exchange Ratio and
otherwise using valuation techniques reasonably acceptable to Parent and the
Company and consistent with the requirements of APB No. 16.
 
     (b) Parent shall not issue fractional shares or pay cash to the holders of
Company Stock Options receiving shares of Parent Common Stock in lieu of issuing
fractional shares of Parent Common Stock. Instead, all fractional shares of
Parent Common Stock issuable under this Section 3.5 shall be decreased to the
nearest whole share.
 
     (c) The Company shall use its reasonable best efforts to cause the holders
of Company Stock Options to execute prior to the Closing Date a form of
acknowledgement reasonably acceptable to Parent regarding their acceptance of
the treatment of Company Stock Options set forth in this Section 3.5 (each a
"Stock Option Acknowledgement").
 
SECTION 3.6  Closing.
 
     The closing (the "Closing") of the transactions contemplated by this
Agreement shall take place at the offices of Pillsbury Madison & Sutro LLP, 101
West Broadway, Suite 1800, San Diego, California, or at any other location
mutually agreeable to Parent and the Company on the second business day
immediately following the date on which the last of the conditions set forth in
Article VIII is fulfilled or waived, or at such other time as Parent and the
Company shall agree (the date on which the Closing occurs is referred to in this
Agreement as the "Closing Date").
 
SECTION 3.7  Closing of the Company's Transfer Books.
 
     At and after the Effective Time, holders of Company Certificates shall
cease to have any rights as stockholders of the Company, except for (a) the
right to an appraisal for Dissenting Shares pursuant to Section 3.1(d) hereof
(but solely as provided by the DGCL), (b) the right to receive shares of Parent
Common Stock pursuant to Section 3.3 hereof and (c) the right to receive cash
for payment of fractional shares pursuant to Section 3.4 hereof. At the
Effective Time, the stock transfer books of the Company shall be closed and no
transfer of shares of Company Stock which were outstanding immediately prior to
the Effective Time shall thereafter be made. If, after the Effective Time,
subject to the terms and conditions of this Agreement, Company Certificates
formerly representing Company Stock are presented to the Surviving Corporation,
they shall be canceled and exchanged for Parent Common Stock in accordance with
this Article III.

                                   ARTICLE IV
 
            REPRESENTATIONS AND WARRANTIES OF PARENT AND ACQUISITION
 
     Parent and Acquisition each represent and warrant to the Company as
follows:
 
SECTION 4.1  Organization and Qualification.
 
     Each of Parent and Acquisition is a corporation duly organized, validly
existing and in good standing under the laws of the State of Delaware and has
the requisite power and authority to own, lease and operate its assets and
properties and to carry on its business as it is now being conducted. Each of
Parent and Acquisition is qualified to do business and is in good standing in
each jurisdiction in which the properties owned, leased or operated by it or the
nature of the business conducted by it makes such qualification necessary,
except where the failure to be so qualified and in good standing would not have
a Parent Material Adverse Effect. As used in this Agreement, a "Parent Material
Adverse Effect" shall mean any event, circumstance, development or occurrence,
individually or when taken together with all other such events, circumstances,
developments or occurrences, causing, resulting in or having, or reasonably
likely to cause, result in or have, a material adverse effect on the business,
operations, properties, assets, condition (financial or other) or results of
operations of Parent and its subsidiaries (as defined in Section 4.2 hereof),
taken as a whole. True, accurate and complete copies of each of Parent's and
Acquisition's Certificates of Incorporation and bylaws, in each case as in
effect on the date hereof, including all amendments thereto, have heretofore
been delivered to the Company.
 
SECTION 4.2  Capitalization.
 
     (a) The authorized capital stock of Parent consists of (i) 98,000,000
shares of Parent Common Stock, par value $.002, of which 33,234,157 shares were
outstanding as of the date of this Agreement, and (ii) 2,000,000 shares of
preferred stock, par value $.002 per share ("Parent Preferred Stock"), of which
no shares were outstanding as of the date of this Agreement. All of the issued
and outstanding shares of Parent Common Stock and Parent Preferred Stock are
validly issued and are fully paid, nonassessable and free of preemptive rights.
 
     (b) The authorized capital stock of Acquisition consists of 100 shares of
Acquisition Common Stock, par value $.01, of which 10 shares are issued and
outstanding, which shares are owned beneficially and of record by Parent.
 
     (c) Except as set forth on Schedule 4.2(c) attached hereto, as of the date
of this Agreement, there are no outstanding subscriptions, options, calls,
contracts, commitments, understandings, restrictions, arrangements, rights or
warrants, including any right of conversion or exchange under any outstanding
security, instrument or other agreement and also including any rights plan or
other anti-takeover agreement, obligating Parent or any subsidiary of Parent to
issue, deliver or sell, or cause to be issued, delivered or sold, additional
shares of the capital stock of Parent or obligating Parent or any subsidiary of
Parent to grant, extend or enter into any such agreement or commitment. There
are no voting trusts, proxies or other agreements or understandings to which
Parent or any subsidiary of Parent is a party or by which Parent or any
subsidiary of Parent is bound with respect to the voting of any shares of
capital stock of Parent. The shares of Parent Common Stock issued to
stockholders of the Company in the Merger will be at the Effective Time duly
authorized, validly issued, fully paid, nonassessable, and free of preemptive
rights. As used in this Agreement, "subsidiary" means, with respect to any party
hereto (a "Subject Party"), any corporation or other organization, whether
incorporated or unincorporated, (i) of which more than fifty percent (50%) of
either the equity interests in, or the voting control of, such corporation or
other organization is, directly or indirectly through subsidiaries or otherwise,
beneficially owned by such Subject Party or (ii) which is a professional
corporation as to which such Subject Party or a subsidiary thereof has executed
a succession or similar stockholder agreement.

SECTION 4.3  Authority; Non-Contravention; Approvals.
 
     (a) Parent and Acquisition each have full corporate power and authority to
enter into this Agreement and, subject to the Parent Required Statutory
Approvals (as defined in Section 4.3(c) hereof), to consummate the transactions
contemplated hereby. This Agreement has been approved by the boards of directors
of Parent and Acquisition and by Parent as the sole stockholder of Acquisition,
and no other corporate proceedings on the part of Parent or Acquisition are
necessary to authorize the execution and delivery of this Agreement or the
consummation by Parent and Acquisition of the transactions contemplated hereby.
This Agreement has been duly executed and delivered by each of Parent and
Acquisition, and, assuming the due authorization, execution and delivery hereof
by the Company, constitutes a valid and legally binding agreement of each of
Parent and Acquisition enforceable against each of them in accordance with its
terms, except that such enforcement may be subject to (i) bankruptcy, fraudulent
conveyance, insolvency, reorganization, moratorium or other similar laws
affecting or relating to enforcement of creditors' rights generally and (ii)
general equitable principles, and except that the availability of equitable
remedies, including specific performance and injunctive relief, is subject to
the discretion of the court before which any proceedings may be brought.
 
     (b) Except as set forth on Schedule 4.3(b) attached hereto, the execution
and delivery of this Agreement by each of Parent and Acquisition do not violate,
conflict with or result in a breach of any provision of, or constitute a default
(or an event which, with notice or lapse of time or both, would constitute a
default) under, or result in the termination of, or accelerate the performance
required by, or result in a right of termination or acceleration under, or
result in the creation of any lien, security interest, charge or encumbrance
upon any of the properties or assets of Parent or any of its subsidiaries under
any of the terms, conditions or provisions of (i) the respective charters or
bylaws of Parent or any of its subsidiaries, (ii) any statute, law, ordinance,
rule, regulation, judgment, decree, order, injunction, writ, permit or license
of any court or governmental authority applicable to Parent or any of its
subsidiaries or any of their respective properties or assets or (iii) any note,
bond, mortgage, indenture, deed of trust, license, franchise, permit,
concession, contract, lease or other instrument, obligation or agreement of any
kind to which Parent or any of its subsidiaries is now a party or by which
Parent or any of its subsidiaries or any of their respective properties or
assets may be bound or affected. The consummation by Parent and Acquisition of
the transactions contemplated hereby will not result in any violation, conflict,
breach, termination, acceleration or creation of liens under any of the terms,
conditions or provisions described in clauses (i) through (iii) of the preceding
sentence, subject to (x) in the case of the terms, conditions or provisions
described in clause (ii) above, obtaining (prior to the Effective Time) the
Parent Required Statutory Approvals (as defined in Section 4.3(c) hereof) and
(y) in the case of the terms, conditions or provisions described in clause (iii)
above, obtaining (prior to the Effective Time) consents required from commercial
lenders, lessors or other third parties named in Schedule 4.3(b) attached
hereto. Set forth on Schedule 4.3(b) attached hereto is a list of hospital
contracts with respect to which the consent of any party other than Parent is
required in order that consummation by Parent of the transactions contemplated
hereby will not result in a breach or termination of the respective contracts.
Excluded from the foregoing sentences of this paragraph (b), insofar as they
apply to the terms, conditions or provisions described in clauses (ii) and (iii)
of the first sentence of this paragraph (b), are such violations, conflicts,
breaches, defaults, terminations, accelerations or creations of liens, security
interests, charges or encumbrances that would not have a Parent Material Adverse
Effect.
 
     (c) Except for (i) the filings by Parent and the Company required by the
Hart-Scott-Rodino Antitrust Improvements Act of 1976, as amended (the "HSR
Act"), (ii) the filing of the Proxy Statement/Prospectus (as defined in Section
4.8 hereof) with the Securities and Exchange Commission (the "Commission")
pursuant to the Securities Act of 1933, as amended (the "Securities Act"), and
the declaration of the effectiveness thereof by the Commission and filings with
various state blue sky authorities, (iii) the making of the Merger Filing with
the Secretary of State of the State of Delaware in connection with the Merger
and (iv) any other required filings with or approvals from applicable Federal
and state governmental authorities (the filings and approvals referred to in
clauses (i) through (iv) are collectively referred to as the "Parent Required
Statutory Approvals"), no declaration, filing or registration with, or notice
to, or authorization, consent or approval of, any governmental or regulatory
body or authority is necessary for the execution and

delivery of this Agreement by Parent or Acquisition or the consummation by
Parent or Acquisition of the transactions contemplated hereby, other than such
declarations, filings, registrations, notices, authorizations, consents or
approvals which, if not made or obtained, as the case may be, would not have a
Parent Material Adverse Effect.
 
SECTION 4.4  Reports and Financial Statements.
 
     Since October 20, 1994, Parent has filed with the Commission all material
forms, statements, reports and documents (including all exhibits, amendments and
supplements thereto) required to be filed by it under each of the Securities
Act, the Securities Exchange Act of 1934, as amended (the "Exchange Act"), and
the respective rules and regulations thereunder, all of which, as amended if
applicable, complied in all material respects at the time of filing with all
applicable requirements of the appropriate act and the rules and regulations
thereunder. Parent has previously delivered or made available to the Company a
copy of its (a) Annual Report on Form 10-K, as amended, for the fiscal years
ended December 31, 1994, 1995 and 1996, and its report on Form 10-Q for the
quarter ended March 31, 1997, each as filed with the Commission, (b) proxy and
information statements relating to (i) all meetings of its stockholders (whether
annual or special) and (ii) actions by written consent in lieu of a
stockholders' meeting from October 20, 1994, until the date hereof, and (c) all
other reports, including quarterly and current reports, or registration
statements filed by Parent with the Commission (the documents referred to in
clauses (a), (b) and (c) are collectively referred to as the "Parent SEC
Reports"). As of their respective dates, the Parent SEC Reports complied in all
material respects with the requirements of the Exchange Act and/or the
Securities Act and the rules and regulations of the Commission thereunder

material respects and (ii) duly paid in full or made adequate provision for the

     The Company is a corporation duly organized, validly existing and in good
standing under the laws of the State of Delaware and has the requisite corporate
power and authority to own, lease and operate its assets and properties and to
carry on its business as it is now being conducted. The Company is qualified to
do business and is in good standing in each jurisdiction in which the properties
owned, leased or operated by it or the nature of the business conducted by it
makes such qualification necessary, except where the failure to be so qualified
and in good standing would not have a Company Material Adverse Effect. As used
in this Agreement, a "Company Material Adverse Effect" shall mean any event,
circumstance, development or occurrence, individually or when taken together
with all other such events, circumstances, developments or occurrences, causing,
resulting in or having, or reasonably likely to cause, result in or have, a
material adverse effect on the business, operations, properties, assets,
condition (financial or other) or results of operations of the Company and its
subsidiaries (as defined in Section 4.2 hereof), taken as a whole. True,
accurate and complete copies of the Company's Certificate of Incorporation and
bylaws, in each case as in effect on the date hereof, including all amendments
thereto, have heretofore been delivered to Parent.
 
SECTION 5.2  Capitalization.
 
     (a) The authorized capital stock of the Company consists of 15,000,000

Company Preferred Stock, par value $.001 per share, of which 25,000 shares have

designated Series B Convertible Preferred Stock. As of the date of this
Agreement, 1,673,500 shares of Company Common Stock and 50,000 shares of Company
Preferred Stock were issued and outstanding (25,000 and 25,000 shares of which
are designated Series A Convertible Preferred Stock and Series B Convertible
Preferred Stock respectively). All of such issued and outstanding shares are
validly issued and are fully paid, nonassessable and free of preemptive rights.
 
     (b) Except as set forth on Schedule 5.2(b) attached hereto, as of the date
hereof there are no outstanding subscriptions, options, calls, contracts,
commitments, understandings, restrictions, arrangements, rights or warrants,
including any right of conversion or exchange under any outstanding security,
instrument or other agreement and also including any rights plan or other
anti-takeover agreement, obligating the Company or any subsidiary of the Company
to issue, deliver or sell, or cause to be issued, delivered or sold, additional
shares of the capital stock of the Company or obligating the Company or any
subsidiary of the Company to grant, extend or enter into any such agreement or
commitment. Except as set forth on Schedule 5.2(b) attached hereto, there are no
voting trusts, proxies or other agreements or understandings to which the
Company or any subsidiary of the Company is a party or by which the Company or
any subsidiary of the Company is bound with respect to the voting of any shares
of capital stock of the Company.
 
     (c) Each Stock Option Acknowledgement executed and delivered by the holder
of a Company Stock Option as contemplated by Section 3.5(a) above shall, from
and after the Effective Time, be binding upon the holder of the Company Stock
Option to which such Stock Option Acknowledgement relates on the terms and
 
                                      A-11

subject to the conditions provided in Section 3.5(a) and such Stock Option
Acknowledgement. Except as set forth on Schedule 5.2(c) attached hereto, none of
the benefits available under the Company Stock Options are subject to
acceleration as a result of the Merger or otherwise, and the Company shall take
no action to permit or foster any such acceleration.
 
SECTION 5.3  Subsidiaries.
 
     Schedule 5.3 sets forth the name, state of incorporation and stockholders
of each subsidiary of the Company. Each subsidiary of the Company is duly
organized, validly existing and in good standing under the laws of its
jurisdiction of incorporation or formation and has the requisite power and
authority to own, lease and operate its assets and properties and to carry on
its business as it is now being conducted. Each subsidiary of the Company is
qualified to do business, and is in good standing, in each jurisdiction in which
the properties owned, leased or operated by it or the nature of the business
conducted by it makes such qualification necessary, except where the failure to
be so qualified and in good standing would not have a Company Material Adverse
Effect. All of the outstanding shares of capital stock of each corporate
subsidiary of the Company are duly authorized, validly issued, fully paid,
nonassessable and free of preemptive rights and are owned directly or indirectly
by the Company, free and clear of any liens, claims, encumbrances, security

forth on Schedule 5.3 attached hereto. There are no subscriptions, options,
warrants, rights, calls, contracts, voting trusts, proxies or other commitments,

with its terms, except that such enforcement may be subject to (i) bankruptcy,
fraudulent conveyance, insolvency, reorganization, moratorium or other similar
laws affecting or relating to enforcement of creditors' rights generally and
(ii) general equitable principles, and except that the availability of equitable
remedies, including specific performance and injunctive relief, is subject to
the discretion of the court before which any proceedings may be brought.
 
     (b) Except as set forth on Schedule 5.4(b) attached hereto, the execution
and delivery of this Agreement by the Company do not violate, conflict with or
result in a breach of any provision of, or constitute a default (or an event
which, with notice or lapse of time or both, would constitute a default) under,
or result in the termination of, or accelerate the performance required by, or
result in a right of termination or acceleration under, or result in the

or practices of Company together with those of its subsidiaries being referred
to as the "Company Plans"). True and complete copies of each Company Plan has

complies in all material respects with the requirements of its terms, ERISA and
the Code. Each Company Plan intended to be qualified under Section 401(a) of the
Code has received a favorable determination letter from the IRS. No Company Plan
is covered by Title IV of ERISA or Section 412 of the Code. Neither the Company
nor any of its subsidiaries has incurred any liability or penalty under Section
4975 of the Code or Section 502(i) of ERISA with respect to any Company Plan. To
the knowledge of the Company, there are no pending, threatened or anticipated
claims against or otherwise involving the Company Plans, except routine claims
for benefits. All material contributions required to be made as of the date of
this Merger Agreement to the Company Plans have been made or properly accounted
for. Neither the Company nor any entity under "common control" with the Company
within the meaning of Section 4001 of ERISA has contributed to or been required
to contribute to, any "multiemployer plan" (as defined in Section 3(37) of
ERISA). No Company Plan provides for post-retirement medical benefits, other
than as required by applicable law.

shareholder agreements ("Minority Shareholder Agreements") and stock option
plans ("Minority Option Plans") relating to such subsidiaries to eliminate the
Minority Holders' interests in each such subsidiary ("Roll-up Transactions").

treated in the Merger as other issued and outstanding Company Stock Options are
treated pursuant to Section 3.5 of this Agreement. If the Roll-up Transactions

providing that such holder shall have
 
                                      A-25
<PAGE>   141
 
no actions, causes of action or claims against the Company or Parent with
respect to such holder's Minority Options other than for a number of shares of
Parent Common Stock and/or Parent Stock Options held in the escrow specifically
to complete the Roll-up Transactions for such subsidiary.
 
     (d) Escrow Provisions. Any shares of Parent Common Stock or Parent Stock
Options held in any escrow pursuant to this Section 7.14 shall constitute shares
or options which would otherwise be issuable to stockholders or optionees of the
Company in the Merger. The terms of each Escrow Agreement and any related escrow
arrangements shall be reasonably agreed upon by Parent and the Company.
 
     (e) Adjustments Following Completion of Roll-up Transactions. If, following
the completion of a Roll-up Transaction for any subsidiary after the Effective

received shares of Parent Common Stock pursuant to Section 3.1 and Section 3.5,
respectively.

July 1, 1997
 
The Board of Directors
Health Partners, Inc.
800 Connecticut Avenue
Norwalk, Connecticut 06854
 
Members of the Board:
 
     You have requested our opinion as to the fairness, from a financial point
of view, to the holders of the common stock of Health Partners, Inc. ("Health
Partners") of the consideration to be received by such holders pursuant to the
terms and subject to the conditions set forth in the Agreement and Plan of
Merger, dated as of July 1, 1997 (the "Merger Agreement"), by and among FPA
Medical Management, Inc. ("FPA"), FPA Acquisition Corp., a wholly owned
subsidiary of FPA ("Acquisition Sub"), and Health Partners. As more fully
described in the Merger Agreement, (i) Acquisition Sub will be merged with and
into Health Partners (the "Merger") and (ii) the outstanding shares of the
common stock, par value $0.001 per share, of Health Partners (the "Health
Partners Common Stock") will be converted into the right to receive that number
of shares of the common stock, par value $0.002 per share, of FPA (the "FPA
Common Stock") having an aggregate value of $115 million (the "Merger
Consideration"), subject to adjustment as more fully specified in the Merger
Agreement if the average closing prices of FPA Common Stock for the 10
consecutive trading days ending on the date that is two trading days prior to
the closing of the Merger is less than $18.00 or greater than $22.00.
 
     In arriving at our opinion, we reviewed the Merger Agreement and held
discussions with certain senior officers, directors and other representatives
and advisors of Health Partners and certain senior officers and other
representatives of FPA concerning the businesses, operations and prospects of
Health Partners and FPA. We examined certain business and financial information
relating to Health Partners and certain publicly available business and
financial information relating to FPA as well as certain financial forecasts and
other information and data for Health Partners and FPA which were provided to or
otherwise discussed with us by the respective managements of Health Partners and
FPA, including information relating to certain strategic implications and
operational benefits anticipated to result from the Merger. We reviewed the
financial terms of the Merger as set forth in the Merger Agreement in relation
to, among other things: current and historical market prices and trading volumes
of FPA Common Stock; the historical and projected earnings and other operating
data of Health Partners and FPA; and the capitalization and financial condition
of Health Partners and FPA. We considered, to the extent publicly available, the
financial terms of certain other similar transactions recently effected which we
considered relevant in evaluating the Merger and analyzed certain financial,
stock market and other publicly available information relating to the businesses
of other companies whose operations we considered relevant in evaluating those
of Health Partners and FPA. We also evaluated the potential pro forma financial
impact of the Merger on FPA. In connection with our engagement, we were
requested to approach on a limited basis, and held discussions with, certain
third parties to solicit indications of interest in a possible acquisition of
Health Partners. In addition to the foregoing, we conducted such other analyses
and examinations and considered such other financial, economic and market
criteria as we deemed appropriate in arriving at our opinion.
 
     In rendering our opinion, we have assumed and relied, without independent
verification, upon the accuracy and completeness of all financial and other
information and data publicly available or furnished to or otherwise reviewed by
or discussed with us. With respect to financial forecasts and other information
and data provided to or otherwise reviewed by or discussed with us, we have been
advised by the managements of Health Partners and FPA that such forecasts and
other information and data were reasonably prepared on bases reflecting the best
currently available estimates and judgments of the managements of Health
Partners and FPA as to the future financial performance of Health Partners and
FPA and the strategic implications and operational benefits anticipated to
result from the Merger. We have assumed, with your consent, that the Merger will
be treated as a pooling of interests in accordance with generally accepted
accounting principles and as a tax-free reorganization for federal income tax
purposes. We also have assumed, with your consent,
 
                                       B-1
<PAGE>   149
 
and have taken into account to the extent relevant to our analysis, that prior
to the consummation of the Merger all outstanding shares of the Series A
Convertible Preferred Stock, par value $0.001 per share, of Health Partners and
Series B Convertible Preferred Stock, par value $0.001 per share, of Health
Partners and all outstanding minority interests in subsidiaries of Health
Partners will be converted into shares of Health Partners Common Stock. We are
not expressing any opinion as to what the value of the FPA Common Stock actually
will be when issued to Health Partners stockholders pursuant to the Merger or
the price at which the FPA Common Stock will trade subsequent to the Merger. We
have not made or been provided with an independent evaluation or appraisal of
the assets or liabilities (contingent or otherwise) of Health Partners or FPA
nor have we made any physical inspection of the properties or assets of Health
Partners or FPA. Our opinion is necessarily based upon information available to
us, and financial, stock market and other conditions and circumstances existing
and disclosed to us, as of the date hereof.
 
     Smith Barney has been engaged to render financial advisory services to
Health Partners in connection with the proposed Merger and will receive a fee
for such services, a significant portion of which is contingent upon the
consummation of the Merger. We also will receive a fee in connection with the
delivery of this opinion. In the ordinary course of our business, we and our
affiliates may actively trade or hold the securities of FPA for our own account
or for the account of our customers and, accordingly, may at any time hold a
long or short position in such securities. We have in the past provided
investment banking services to FPA unrelated to the proposed Merger, for which
services we have received compensation. In addition, we and our affiliates
(including Travelers Group Inc. and its affiliates) may maintain relationships
with Health Partners and FPA.
 
     Our advisory services and the opinion expressed herein are provided for the
information of the Board of Directors of Health Partners in its evaluation of
the proposed Merger, and our opinion is not intended to be and does not
constitute a recommendation to any stockholder as to how such stockholder should
vote on the proposed Merger. Our opinion may not be published or otherwise used
or referred to, nor shall any public reference to Smith Barney be made, without
our prior written consent.
 
     Based upon and subject to the foregoing, our experience as investment
bankers, our work as described above and other factors we deemed relevant, we
are of the opinion that, as of the date hereof, the Merger Consideration is
fair, from a financial point of view, to the holders of Health Partners Common
Stock.
 
                                          Very truly yours,
 
                                          SMITH BARNEY INC.

                         DELAWARE GENERAL CORPORATIONS
                                LAW SECTION 262
 
SEC. 262. APPRAISAL RIGHTS
 
     (a) Any stockholder of a corporation of this State who holds shares of
stock on the date of the making of a demand pursuant to subsection (d) of this
section with respect to such shares, who continuously holds such shares through
the effective date of the merger or consolidation, who has otherwise complied
with subsection (d) of this section and who has neither voted in favor of the
merger or consolidation nor consented thereto in writing pursuant to sec. 228 of
this title shall be entitled to an appraisal by the Court of Chancery of the
fair value of his shares of stock under the circumstances described in
subsections (b) and (c) of this section. As used in this section, the word
"stockholder" means a holder of record of stock in a stock corporation and also
a member of record of a nonstock corporation; the words "stock" and "share" mean
and include what is ordinarily meant by those words and also membership or
membership interest of a member of a nonstock corporation; and the words
"depository receipt" mean a receipt or other instrument issued by a depository
representing an interest in one or more shares, or fractions thereof, solely of
stock of a corporation, which stock is deposited with the depository.
 
     (b) Appraisal rights shall be available for the shares of any class or
series of stock of a constituent corporation in a merger or consolidation to be
effected pursuant to sec. 251 (other than a merger effected pursuant to
subsection (g) of sec. 251), sec. 252, sec. 254, sec. 257, sec. 258, sec. 263 or
sec. 264 of this title:
 
          (1) Provided, however, that no appraisal rights under this section
     shall be available for the shares of any class or series of stock, which
     stock, or depository receipts in respect thereof, at the record date fixed
     to determine the stockholders entitled to receive notice of and to vote at
     the meeting of stockholders to act upon the agreement of merger or
     consolidation, were either (i) listed on a national securities exchange or
     designated as a national market system security on an interdealer quotation
     system by the National Association of Securities Dealers, Inc. or (ii) held
     of record by more than 2,000 holders; and further provided that no
     appraisal rights shall be available for any shares of stock of the
     constituent corporation surviving a merger if the merger did not require
     for its approval the vote of the stockholders of the surviving corporation
     as provided in subsection (f) of sec. 251 of this title.
 
          (2) Notwithstanding paragraph (1) of this subsection, appraisal rights
     under this section shall be available for the shares of any class or series
     of stock of a constituent corporation if the holders thereof are required
     by the terms of an agreement of merger or consolidation pursuant to
     sections 251, 252, 254, 257, 258, 263 and 264 of this title to accept for
     such stock anything except:
 
             a. Shares of stock of the corporation surviving or resulting from
        such merger or consolidation, or depository receipts in respect thereof;
 
             b. Shares of stock of any other corporation, or depository receipts
        in respect thereof, which shares of stock or depository receipts at the
        effective date of the merger or consolidation will be either listed on a
        national securities exchange or designated as a national market system
        security on an interdealer quotation system by the National Association
        of Securities Dealers, Inc. or held of record by more than 2,000
        holders;
 
             c. Cash in lieu of fractional shares or fractional depository
        receipts described in the foregoing subparagraphs a. and b. of this
        paragraph; or
 
             d. Any combination of the shares of stock, depository receipts and
        cash in lieu of fractional shares or fractional depository receipts
        described in the foregoing subparagraphs a., b. and c. of this
        paragraph.

          (3) In the event all of the stock of a subsidiary Delaware corporation
     party to a merger effected under sec. 253 of this title is not owned by the
     parent corporation immediately prior to the merger, appraisal rights shall
     be available for the shares of the subsidiary Delaware corporation.
 
     (c) Any corporation may provide in its certificate of incorporation that
appraisal rights under this section shall be available for the shares of any
class or series of its stock as a result of an amendment to its certificate of
incorporation, any merger or consolidation in which the corporation is a
constituent corporation or the sale of all or substantially all of the assets of
the corporation. If the certificate of incorporation contains such a provision,
the procedures of this section, including those set forth in subsections (d) and
(e) of this section, shall apply as nearly as is practicable.
 
     (d) Appraisal rights shall be perfected as follows:
 
          (1) If a proposed merger or consolidation for which appraisal rights
     are provided under this section is to be submitted for approval at a
     meeting of stockholders, the corporation, not less than 20 days prior to
     the meeting, shall notify each of its stockholders who was such on the
     record date for such meeting with respect to shares for which appraisal
     rights are available pursuant to subsection (b) or (c) hereof that
     appraisal rights are available for any or all of the shares of the
     constituent corporations, and shall include in such notice a copy of this
     section. Each stockholder electing to demand the appraisal of his shares
     shall deliver to the corporation, before the taking of the vote on the
     merger or consolidation, a written demand for appraisal of his shares. Such
     demand will be sufficient if it reasonably informs the corporation of the
     identity of the stockholder and that the stockholder intends thereby to
     demand the appraisal of his shares. A proxy or vote against the merger or
     consolidation shall not constitute such a demand. A stockholder electing to
     take such action must do so by a separate written demand as herein
     provided. Within 10 days after the effective date of such merger or
     consolidation, the surviving or resulting corporation shall notify each
     stockholder of each constituent corporation who has complied with this
     subsection and has not voted in favor of or consented to the merger or
     consolidation of the date that the merger or consolidation has become
     effective; or
 
          (2) If the merger or consolidation was approved pursuant to sec. 228
     or sec. 253 of this title, each constituent corporation, either before the
     effective date of the merger or consolidation or within ten days
     thereafter, shall notify each of the holders of any class or series of
     stock of such constituent corporation who are entitled to appraisal rights
     of the approval of the merger or consolidation and that appraisal rights
     are available for any or all shares of such class or series of stock of
     such constituent corporation, and shall include in such notice a copy of
     this section; provided that, if the notice is given on or after the
     effective date of the merger or consolidation, such notice shall be given
     by the surviving or resulting corporation to all such holders of any class
     or series of stock of a constituent corporation that are entitled to
     appraisal rights. Such notice may, and, if given on or after the effective
     date of the merger or consolidation, shall, also notify such stockholders
     of the effective date of the merger or consolidation. Any stockholder
     entitled to appraisal rights may, within twenty days after the date of
     mailing of such notice, demand in writing from the surviving or resulting
     corporation the appraisal of such holder's shares. Such demand will be
     sufficient if it reasonably informs the corporation of the identity of the
     stockholder and that the stockholder intends thereby to demand the
     appraisal of such holder's shares. If such notice did not notify
     stockholders of the effective date of the merger or consolidation, either
     (i) each such constituent corporation shall send a second notice before the
     effective date of the merger or consolidation notifying each of the holders
     of any class or series of stock of such constituent corporation that are
     entitled to appraisal rights of the effective date of the merger or
     consolidation or (ii) the surviving or resulting corporation shall send
     such a second notice to all such holders on or within 10 days after such
     effective date; provided, however, that if such second notice is sent more
     than 20 days following the sending of the first notice, such second notice
     need only be sent to each stockholder who is entitled to appraisal rights
     and who has demanded appraisal of such holder's shares in accordance with
     this subsection. An affidavit of the secretary or assistant secretary or of
     the transfer agent of the corporation that is required to give either
     notice that such notice has been given shall, in the absence of fraud, be
     prima facie evidence of the facts stated therein. For purposes of
     determining the stockholders entitled to receive either notice, each
     constituent corporation may fix, in advance, a record date that shall be
     not more than 10 days prior to the
 
                                       C-2
<PAGE>   152
 
     date the notice is given; provided that, if the notice is given on or after
     the effective date of the merger or consolidation, the record date shall be
     such effective date. If no record date is fixed and the notice is given
     prior to the effective date, the record date shall be the close of business
     on the day next preceding the day on which the notice is given.
 
     (e) Within 120 days after the effective date of the merger or
consolidation, the surviving or resulting corporation or any stockholder who has
complied with subsections (a) and (d) hereof and who is otherwise entitled to
appraisal rights, may file a petition in the Court of Chancery demanding a
determination of the value of the stock of all such stockholders.
Notwithstanding the foregoing, at any time within 60 days after the effective
date of the merger or consolidation, any stockholder shall have the right to
withdraw his demand for appraisal and to accept the terms offered upon the
merger or consolidation within 120 days after the effective date of the merger
or consolidation, any stockholder who has complied with the requirements of
subsections (a) and (d) hereof, upon written request, shall be entitled to
receive from the corporation surviving the merger or resulting from the
consolidation a statement setting forth the aggregate number of shares not voted
in favor of the merger or consolidation and with respect to which demands for
appraisal have been received and the aggregate number of holders of such shares.
Such written statement shall be mailed to the stockholder within 10 days after
his written request for such a statement is received by the surviving or
resulting corporation or within 10 days after expiration of the period for
delivery of demands for appraisal under subsection (d) hereof, whichever is
later.
 
     (f) Upon the filing of any such petition by a stockholder, service of a
copy thereof shall be made upon the surviving or resulting corporation, which
shall within 20 days after such service file in the office of the Register in
Chancery in which the petition was filed a duly verified list containing the
names and addresses of all stockholders who have demanded payment for their
shares and with whom agreements as to the value of their shares have not been
reached by the surviving or resulting corporation. If the petition shall be
filed by the surviving or resulting corporation, the petition shall be
accompanied by such a duly verified list. The Register in Chancery, if so
ordered by the Court, shall give notice of the time and place fixed for the
hearing of such petition by registered or certified mail to the surviving or
resulting corporation and to the stockholders shown on the list at the addresses
therein stated. Such notice shall also be given by 1 or more publications at
least 1 week before the day of the hearing, in a newspaper of general
circulation published in the City of Wilmington, Delaware or such publication as
the Court deems advisable. The forms of the notices by mail and by publication
shall be approved by the Court, and the costs thereof shall be borne by the
surviving or resulting corporation.
 
     (g) At the hearing on such petition, the Court shall determine the
stockholders who have complied with this section and who have become entitled to
appraisal rights. The Court may require the stockholders who have demanded an
appraisal for their shares and who hold stock represented by certificates to
submit their certificates of stock to the Register in Chancery for notation
thereon of the pendency of the appraisal proceedings; and if any stockholder
fails to comply with such direction, the Court may dismiss the proceedings as to
such stockholder.
 
     (h) After determining the stockholders entitled to an appraisal, the Court
shall appraise the shares, determining their fair value exclusive of any element
of value arising from the accomplishment or expectation of the merger or
consolidation, together with a fair rate of interest, if any, to be paid upon
the amount determined to be the fair value. In determining such fair value, the
Court shall take into account all relevant factors. In determining the fair rate
of interest, the Court may consider all relevant factors, including the rate of
interest which the surviving or resulting corporation would have had to pay to
borrow money during the pendency of the proceeding. Upon application by the
surviving or resulting corporation or by any stockholder entitled to participate
in the appraisal proceeding, the Court may, in its discretion, permit discovery
or other pretrial proceedings and may proceed to trial upon the appraisal prior
to the final determination of the stockholder entitled to an appraisal. Any
stockholder whose name appears on the list filed by the surviving or resulting
corporation pursuant to subsection (f) of this section and who has submitted his
certificates of stock to the Register in Chancery, if such is required, may
participate fully in all proceedings until it is finally determined that he is
not entitled to appraisal rights under this section.
 
                                       C-3
<PAGE>   153
 
     (i) The Court shall direct the payment of the fair value of the shares,
together with interest, if any, by the surviving or resulting corporation to the
stockholders entitled thereto. Interest may be simple or compound, as the Court
may direct. Payment shall be so made to each such stockholder, in the case of
holders of uncertificated stock forthwith, and the case of holders of shares
represented by certificates upon the surrender to the corporation of the
certificates representing such stock. The Court's decree may be enforced as
other decrees in the Court of Chancery may be enforced, whether such surviving
or resulting corporation be a corporation of this State or of any state.
 
     (j) The costs of the proceeding may be determined by the Court and taxed
upon the parties as the Court deems equitable in the circumstances. Upon
application of a stockholder, the Court may order all or a portion of the
expenses incurred by any stockholder in connection with the appraisal
proceeding, including, without limitation, reasonable attorney's fees and the
fees and expenses of experts, to be charged pro rata against the value of all
the shares entitled to an appraisal.
 
     (k) From and after the effective date of the merger or consolidation, no
stockholder who has demanded his appraisal rights as provided in subsection (d)
of this section shall be entitled to vote such stock for any purpose or to
receive payment of dividends or other distributions on the stock (except
dividends or other distributions payable to stockholders of record at a date
which is prior to the effective date of the merger or consolidation); provided,
however, that if no petition for an appraisal shall be filed within the time
provided in subsection (e) of this section, or if such stockholder shall deliver
to the surviving or resulting corporation a written withdrawal of his demand for
an appraisal and an acceptance of the merger or consolidation, either within 60
days after the effective date of the merger or consolidation as provided in
subsection (e) of this section or thereafter with the written approval of the
corporation, then the right of such stockholder to an appraisal shall cease.
Notwithstanding the foregoing, no appraisal proceeding in the Court of Chancery
shall be dismissed as to any stockholder without the approval of the Court, and
such approval may be conditioned upon such terms as the Court deems just.
 
     (l) The shares of the surviving or resulting corporation to which the
shares of such objecting stockholders would have been converted had they
assented to the merger or consolidation shall have the status of authorized and
unissued shares of the surviving or resulting corporation.

ITEM 20.  INDEMNIFICATION OF DIRECTORS AND OFFICERS.
 
     Section 145 of the General Corporation Law of the State of Delaware
provides that a corporation may indemnify its officers, directors, employees and
agents (or persons who have served, at the corporation's request, as officers,
directors, employees or agents of another corporation) against the expenses,
including attorneys' fees, actually and reasonably incurred by them in
connection with the defense of any action by reason of being or having been
directors, officers, employees or agents, if such person shall have 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 with respect to any criminal action or
proceedings, had no reason to believe his conduct was unlawful, except that if
such action shall be in the right of the corporation, no such indemnification
shall be provided as to any claim, issue or matter as to which such person shall
have been adjudged to have been liable to the corporation unless and only to the
extent that the Court of Chancery of the State of Delaware, or any other court
in which the suit was brought, shall determine upon application that, 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.
 
     FPA's Certificate of Incorporation, as amended, has the following
indemnification provisions:
 
          "SEVENTH"
 
     A. Each person who was or is a party or is threatened to be made a party to
        or is involved in any threatened, pending or completed action, suit or
        proceeding, whether civil, criminal, administrative or investigative
        (hereinafter a "proceeding"), by reason of the fact that he or she, or a
        person of whom he or she is the legal representative, is or was a
        director or officer of the Corporation or is or was serving at the
        request of the 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,
        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 the Corporation to the fullest
        extent authorized by the Delaware General Corporation Law, as the same
        exists or may hereafter be amended (but, in the case of any such
        amendment, only to the extent that such amendment permits the
        Corporation to provide broader indemnification rights than said law
        permitted the Corporation to provide prior to such amendment), against
        all expense, liability and loss (including attorneys' fees, judgements,
        fines, ERISA excise taxes or penalties and amounts paid or to be paid in
        settlement) actually and reasonably incurred or suffered by such person
        in connection therewith, and such indemnification shall continue as to a
        person who has ceased to be a director, officer, employee or agent and
        shall inure to the benefit of his or her heirs, executors and
        administrators; provided, however, that, except as provided in Paragraph
        B hereof, the Corporation shall indemnify any such person seeking
        indemnification in connection with a proceeding (or part thereof)
        initiated by such person only if such proceeding (or part thereof) was
        authorized by the Board of Directors of the Corporation. The right to
        indemnification conferred in this Article SEVENTH shall be a contract
        right and shall include the right to be paid by the Corporation the
        expenses incurred in defending any such proceeding in advance of its
        final disposition; provided, however, that, if the Delaware General
        Corporation Law requires, the payment of such expenses incurred by a
        director or officer in his or her capacity as a director or officer (and
        not in any other capacity in which service was or is rendered by such
        person while a director or officer, including, without limitation,
        service to an employee benefit plan) in advance of the final disposition
        of a proceeding, shall be made only upon delivery to the Corporation of
        an undertaking, by or on behalf of such director or officer, to repay
        all amounts so advanced if it shall ultimately be determined that such
        director or officer is not entitled to be indemnified under this Article
        SEVENTH or otherwise. The Corporation may, by action of its Board
 
                                      II-1
<PAGE>   155
 
        of Directors, provide indemnification to employees and agents of the
        Corporation with the same scope and effect as the foregoing
        indemnification of directors and officers.
 
     B. If a claim under Paragraph A of this Article SEVENTH is not paid in full
        by the Corporation within thirty days after a written claim has been
        received by the Corporation, the claimant may at any time thereafter
        bring suit against the Corporation to recover the unpaid amount of the
        claim and, if successful in whole or in part, the claimant shall be
        entitled to be paid also the expense of prosecuting such claim. It shall
        be a defense to any such action (other than a action brought to enforce
        a claim for expenses incurred in defending any proceeding in advance of
        its final disposition where the required undertaking, if any is
        required, has been tendered to the Corporation) that the claimant has
        not met the standards of conduct which make it permissible under the
        Delaware General Corporation Law for the Corporation to indemnify the
        claimant for the amount claimed, but the burden of providing such
        defense shall be on the Corporation. 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 action that indemnification of the claimant is
        proper in the circumstances because he or she has met the applicable
        standard of conduct set forth in the Delaware General Corporation Law,
        nor an actual determination by the Corporation (including its Board of
        Directors, independent legal counsel, or its stockholders) that the
        claimant has not met such applicable standard of conduct, shall be a
        defense to the action or create a presumption that the claimant has not
        met the applicable standard of conduct.
 
     C. The right to indemnification and the payment of expenses incurred in
        defending a proceeding in advance of its final disposition conferred in
        this Article SEVENTH shall not be exclusive of any other right which any
        person may have or hereafter acquire under any statute, provision of the
        Certificate of Incorporation, by-law, agreement, vote of stockholders or
        disinterested directors or otherwise.
 
     D. The Corporation may maintain insurance, at its expense, to protect
        itself and any person who 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 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 Delaware General Corporation Law.
 
     FPA's By-laws similarly provide that FPA shall indemnify its officers and
directors to the fullest extent permitted by the Delaware Law.
 
     In addition, FPA has entered into individual indemnification agreements
(the "Indemnification Agreements") with each of the directors. The general
effect on directors' liabilities is set forth in the provisions of the
Indemnification Agreements summarized below:
 
     Proceedings Other Than Proceedings by or in the Right of FPA. A director
shall be entitled to the rights of indemnification if, by reason of his position
with FPA, he is, or is threatened to be made, a party to any threatened,
pending, or completed proceeding, other than a proceeding by or in the right of
FPA. In such case, such director shall be indemnified against all expenses,
judgments, penalties, fines and amounts paid in settlement actually and
reasonably incurred by him or on his behalf in connection with such proceeding
or any claim, issue or matter therein, if he acted in good faith and in a manner
he reasonably believed to be in or not opposed to the best interests of FPA and,
with respect to any criminal proceeding, had no reasonable cause to believe his
conduct was unlawful.
 
     Proceedings by or in the Right of Company. Generally, a director shall be
entitled to the rights of indemnification if, by reason of his position with
FPA, he is, or is threatened to be made, a party to any threatened, pending or
completed proceeding brought by or in the right of FPA to procure a judgment in
its favor. In such case, the director shall be indemnified against all expenses
actually and reasonably incurred by him or on his behalf in connection with such
proceeding if he acted in good faith and in a manner he reasonably believed to
be in or not opposed to the best interests of FPA; provided, however, that if
applicable law so provides, no indemnification against such expenses shall be
made in respect of any claim, issue or
 
                                      II-2
<PAGE>   156
 
matter in such proceeding as to which the director shall have been adjudged to
be liable to FPA unless and to the extent that the Court of Chancery of the
State of Delaware, or the court in which such proceeding shall have been brought
or is pending, shall determine that such indemnification may be made.
 
     Indemnification for Expenses of a Party Who is Wholly or Partly
Successful. Notwithstanding any other provision of the Indemnification
Agreements, to the extent that the director is, by reason of his position with
FPA, a party to and is successful, on the merits or otherwise, in any
proceeding, he shall be indemnified against all expenses actually and reasonably
incurred by him or on his behalf in connection therewith. If the director is not
wholly successful in such proceeding but is successful, on the merits or
otherwise, as to one or more but less than all claims, issues or matters in such
proceeding, FPA shall indemnify the director against all expenses actually and
reasonably incurred by him or on his behalf in connection with each successfully
resolved claim, issue or matter.

 * Incorporated by reference to the exhibit to the Registrant's Registration
   Statement on Form S-1, Reg. No. 33-97456, at the exhibit number set forth
   opposite such exhibit's description above.
 
** Registrant has requested confidential treatment from the Securities and
   Exchange Commission for portions of this exhibit, which confidential portions
   have been filed separately.
 
 + To be filed by amendment.
 
ITEM 22. UNDERTAKINGS
 
     The undersigned Registrant hereby undertakes that, for purposes of
determining any liability under the Securities Act of 1933, each filing of the
registrant's annual report pursuant to section 13(a) or section 15(d) of the
Securities Exchange Act of 1934 (and, where applicable, each filing of an
employee benefit plan's annual report pursuant to section 15(d) of the
Securities Exchange Act of 1934) that is incorporated by reference in the
registration statement shall be deemed to be a new registration statement
relating to the
 
                                      II-5
<PAGE>   159
 
securities offered therein, and the offering of such securities at that time
shall be deemed to be the initial bona fide offering thereof.
 
     The undersigned Registrant hereby undertakes as follows: that prior to any
public reoffering of the securities registered hereunder through use of a
prospectus which is a part of this registration statement, by any person or
party who is deemed to be an underwriter within the meaning of Rule 145(c), the
issuer undertakes that such reoffering prospectus will contain the information
called for by the applicable registration form with respect to reofferings by
persons who may be deemed underwriters, in addition to the information called
for by the other Items of the applicable form.
 
     The Registrant hereby undertakes that every prospectus (i) that is filed
pursuant to the paragraph immediately preceding, or (ii) that purports to meet
the requirements of section 10(a)(3) of the Securities Act of 1933, as amended
(the "Securities Act"), and is used in connection with an offering of securities
subject to Rule 415, will be filed as a part of an amendment to the registration
statement and will not be used until such amendment is effective, and that, for
purposes 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.
 
     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 indemnification by it is against public
policy as expressed in the Securities Act and will be governed by the final
application of such issue.
 
     The undersigned Registrant hereby undertakes to respond to requests for
information that is incorporated by reference into the prospectus pursuant to
Items 4, 10(b), 11, or 13 of this Form, within one business day of receipt of
such request, and to send the incorporated documents by first class mail or
other equally prompt means. This includes information contained in documents
filed subsequent to the effective date of the registration statement through the
date of responding to the request.
 
     The undersigned Registrant hereby undertakes to supply by means of a
post-effective amendment all information concerning a transaction, and the
company being acquired involved therein, that was not the subject of and
included in the registration statement when it became effective.

Date, a Shelf Registration Statement for an offering to be made on a continuous
basis pursuant to Rule 415 covering all of the Restricted Securities. The Shelf

Securities for resale by the Holders in the manner or manners reasonably
designated by them. The Company shall not permit any securities other than the

Securities Act as promptly as is practicable following the filing thereof, with
a goal of having the Shelf Registration Statement declared effective on or prior
to the Effectiveness Target Date, and (subject to Section 7 hereof) to keep the

the Company shall use its reasonable efforts to cause any such post effective

Restricted Securities (the "Effectiveness Period").


                                       3
<PAGE>   5
        (b) The Company shall use its reasonable best efforts to keep the Shelf
Registration Statement continuously effective (except during periods following
the filing of a post effective amendment thereto and prior to the declaration of
the effectiveness of such post effective amendment; provided, the Company shall
use its reasonable best efforts to cause any such post effective amendment to be
declared effective as soon as practicable) by supplementing and amending the
Shelf Registration Statement as required by the rules, regulations or
instructions applicable to the registration form used for such Shelf
Registration Statement if required by the Securities Act or reasonably requested
by the Holders.

3.      Registration Procedures

        In connection with the Company's registration obligations hereunder, the
Company shall effect such registration on the appropriate form available for the
sale of the Restricted Securities to permit the sale of the Restricted
Securities in accordance with the method or methods of disposition thereof
specified by the Holders, and pursuant thereto the Company shall as
expeditiously as reasonably possible:

        (a) No fewer than five Business Days prior to the initial filing of the
Shelf Registration Statement or Prospectus and, if practical, no fewer than two
Business Days prior to the filing of any amendment or supplement thereto (other
than any document that would be incorporated or deemed to be incorporated
therein by reference), furnish to the Holders, copies of all such documents
proposed to be filed, which documents, if practical (other than those
incorporated or deemed to be incorporated by reference) will be subject to the
review of such Holders. The Company shall not file such Shelf Registration
Statement or related Prospectus or any amendments or supplements thereto to
which the Holders covered thereby shall reasonably object on a timely basis;

        (b) Prepare and file with the Commission such amendments, including
post-effective amendments, to each Shelf Registration Statement as may be
necessary to keep such Shelf Registration Statement continuously effective for
the Effectiveness Period; cause the related Prospectus to be supplemented by any
required Prospectus supplement, and as so supplemented to be filed pursuant to
Rule 424 under the Securities Act; and comply with the provisions of the
Securities Act and the Exchange Act with respect to the disposition of all
securities covered by such Shelf Registration Statement during such period in
accordance with the intended methods of disposition by the selling Holders
thereof contemplated hereby and set forth in such Shelf Registration Statement
as so amended or in such Prospectus as so supplemented.

        (c) Notify the Holders promptly (and in the case of an event specified
by clause (i)(A) of this paragraph, if practical, in no event fewer than two
Business Days prior to such filing), and (if requested by any such Person),
confirm such notice in writing, (i)(A) when a Prospectus or any Prospectus
Supplement or post-effective amendment is proposed to be filed, and (B) with
respect to the Shelf Registration Statement or any post-effective amendment,
when the same has become effective, (ii) of any request by the Commission or any
other federal or state governmental authority for amendments or supplements to
the Shelf Registration Statement or related Prospectus or for additional
information, (iii) of the issuance by the Commission, any state securities
commission, any other governmental agency or any court of any stop order, order
or injunction 


                                       4
<PAGE>   6
suspending or enjoining the use or the effectiveness of the Shelf Registration
Statement or the Initiation of any proceedings for that purpose, (iv) of the
receipt by the Company of any notification with respect to the suspension of the
qualification or exemption from qualification of any of the Restricted
Securities for sale in any jurisdiction, or the initiation or threat of any
proceeding for such purpose, and (v) of the happening of any event that makes
any statement made in such Shelf Registration Statement or related Prospectus or
any document incorporated or deemed to be incorporated therein by reference
untrue in any material respect or that requires the making of any changes in
such Shelf Registration Statement, Prospectus or documents so that, in the case
of the Shelf Registration Statement, it will not contain any untrue statement of
a material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, not misleading, and that
in the case of the Prospectus, it will not contain any untrue statement of a
material fact or omit to state any material fact required to be stated therein
or necessary in order to make the statements therein, in light of the
circumstances under which they were made, not misleading;

        (d) Use its reasonable best efforts to avoid the issuance of, or, if
issued, obtain the withdrawal of any order enjoining or suspending the use or
effectiveness of the Shelf Registration Statement or the lifting of any
suspension of the qualification (or exemption from qualification) of any of the
Restricted Securities for sale in any jurisdiction, at the earliest reasonable
practicable moment;

        (e) If requested by the Holders, (i) promptly incorporate in a
Prospectus supplement or post-effective amendment such information as Holders
indicate relates to them or otherwise reasonably request be included therein,
and (ii) make all required filings of such Prospectus supplement or such
post-effective amendment as soon as practicable after the Company has received
notification of the matters to be incorporated in such Prospectus supplement or
post-effective amendment; provided, however, that the Company shall not be
required to take any action pursuant to this Section 3(e) that would, in the
opinion of counsel for the Company, violate applicable law;

        (f) Furnish to each Holder without charge, at least one conformed copy
of the Shelf Registration Statement and each amendment thereto, including
financial statements (but excluding schedules, all documents incorporated or
deemed to be incorporated therein by reference);

        (g) Deliver to each Holder as many copies of the Prospectus or
Prospectuses (including each form of prospectus) and each amendment or
supplement thereto as such Persons reasonably request; and the Company hereby
consents to the use of such Prospectus and each amendment or supplement thereto
by each of the Holders in connection with the offering and sale of the
Restricted Securities covered by such Prospectus and any amendment or supplement
thereto;

        (h) Prior to any public offering of the Restricted Securities, use its
reasonable best efforts to register or qualify or cooperate with the Holders in
connection with the registration or qualification (or exemption from such
registration or qualification) of such Restricted Securities for offer and sale
under the securities or "Blue Sky" laws of such jurisdictions within the United
States as any Holder reasonably requests in writing and to cause the offering of
the Restricted Securities covered by the Shelf Registration Statement to be
registered with or approved by such 


                                       5
<PAGE>   7
other governmental agencies or authorities within the United States, except as
may be required as a consequence of the selling Holder's business (in which case
the Company will cooperate in all reasonable respects with the filing of such
Shelf Registration Statement therewith and granting of approvals thereby), as
may be necessary to enable the selling Holders to consummate the disposition of
such Restricted Securities; keep each such registration or qualification (or
exemption therefrom) or approval effective during the period such Shelf
Registration Statement is required to be kept effective and do any and all other
acts necessary or advisable to enable the disposition in such jurisdictions of
the Restricted Securities covered by the Shelf Registration Statement; provided,
however, that the Company shall not be required to qualify generally to do
business in any jurisdiction where it is not then so qualified or to take any
action that would subject it to general service of process in any such
jurisdiction where it is not then so subject or subject the Company to any tax
in any such jurisdiction where it is not then so subject;

        (i) In connection with any sale or transfer of the Restricted Securities
that will result in such securities no longer being the Restricted Securities,
cooperate with the Holders to facilitate the timely preparation and delivery of
certificates representing the Restricted Securities to be sold, which
certificates shall not bear any restrictive legends and shall be in a form
eligible for deposit with The Depository Trust Company and to enable such
Restricted Securities to be in such denominations and registered in such names
as the Holders may request at least two Business Days prior to any sale of the
Restricted Securities;

        (j) Upon the occurrence of any event contemplated by Section 3(c)(v)
hereof, as promptly as practicable, prepare a supplement or amendment,
including, if appropriate, a post-effective amendment, to the Shelf Registration
Statement or a supplement to the related Prospectus or any document incorporated
or deemed to be incorporated therein by reference, and file any other required
document so that, as thereafter delivered, such Prospectus will not contain an
untrue statement of a material fact or omit to state a material fact required to
be stated therein or necessary in order to make the statements therein, in light
of the circumstances under which they were made, not misleading;

        (k) Comply with applicable rules and regulations of the Commission and
make generally available to its security holders earning statements satisfying
the provisions of Section 11(a) of the Securities Act and Rule 158 thereunder
(or any similar rule promulgated under the Securities Act), no later than 45
days after the end of any 12-month period (or 90 days after the end of any
12-month period if such period is a fiscal year) commencing on the first day of
the first fiscal quarter after the effective date of the Shelf Registration
Statement, which statement shall cover said period, consistent with the
requirements of Rule 158; and

        (l) List all Common Stock covered by such Shelf Registration Statement
on the exchange or system, if any, on which the Common Stock of the Company is
then listed.

        The Company may require each seller of the Restricted Securities as to
which any registration is being effected to: (i) furnish to the Company such
information regarding the distribution of such Restricted Securities as is
required by law to be disclosed in the Shelf Registration Statement and (ii)
provide to the Company a signed writing accepting and acknowledging its rights
and obligations hereunder. The Company may exclude from such 


                                       6
<PAGE>   8
registration the Restricted Securities of any holder of Restricted Securities
who unreasonably fails to furnish such information or signed writing at least 5
Business Days prior to the effective date of such Shelf Registration Statement.

        Each Holder agrees by acquisition of the Restricted Securities that,
upon receipt of any notice from the Company of the happening of any event of the
kind described in Section 3(c)(ii), 3(c)(iii), 3(c)(iv), or 3(c)(v) hereof, such
Holder will forthwith discontinue disposition of such Restricted Securities
covered by such Shelf Registration Statement or Prospectus until such Holder's
receipt of the copies of the supplemented or amended Prospectus contemplated by
Section 3(i) hereof, or until it is advised in writing (the "Advice") by the
Company that the use of the applicable Prospectus may be resumed, and, in either
case, has received copies of any additional or supplemental filings that are
incorporated or deemed to be incorporated by reference in such Prospectus.

        The registration rights of the Holders pursuant to this Agreement and
the ability to offer and sell Restricted Securities pursuant to the Shelf
Registration Statement are subject to the conditions and limitations contained
in this paragraph and Section 7, and each Holder will be deemed to have agreed
with the Company that if the Board of Directors of the Company determines in its
good faith judgment, as evidenced by a resolution of the Board of Directors,
that the use of any Prospectus would require the disclosure of material
information that the Company has a bona fide business purpose for preserving as
confidential or the disclosure of which would impede the Company's ability to
consummate a significant transaction, and that the Company is not otherwise
required by applicable securities laws or regulations to disclose, upon written
notice of such determination by the Company, the rights of the Holders to offer,
sell or distribute any Restricted Securities pursuant to the Shelf Registration
Statement or to require the Company to take action with respect to the
registration or sale of any Restricted Securities pursuant to the Shelf
Registration Statement shall be suspended until the date upon which the Company
notifies the Holders in writing that suspension of such rights for the grounds
set forth in this paragraph is no longer necessary subject to the limits set
forth in Section 7, and the Company agrees to give such notice as promptly as
practicable following the date that such suspension of rights is no longer
necessary.

4.      Registration Expenses

        All fees and expenses incident to the performance of or compliance with
this Agreement by the Company shall be borne by it whether or not the Shelf
Registration Statement is filed or becomes effective and whether or not any
securities are issued or sold pursuant to the Shelf Registration Statement. The
fees and expenses referred to in the foregoing sentence shall include, without
limitation, (a) all registration and filing fees (including, without limitation,
fees and expenses in compliance with securities or "Blue Sky" laws (b) printing
expenses (including, without limitation, expenses of printing Prospectuses), (c)
messenger, telephone and delivery expenses, (d) fees and disbursements of
counsel for the Company; (e) Securities Act liability insurance, if the Company
desires such insurance, and (f) fees and expenses of all other Persons retained
by the Company. In addition, the Company shall pay its internal expenses
(including, without limitation, all salaries and expenses of its officers and
employees performing legal or accounting duties), the expense of any annual
audit, and the fees and expenses incurred in 


                                       7
<PAGE>   9
connection with the listing of the securities to be registered on any securities
exchange. Notwithstanding the foregoing or anything in this Agreement to the
contrary, each Holder shall pay all underwriting discounts and commissions of
any underwriters or broker-dealers with respect to any Restricted Securities
sold by it.

5.      Indemnification

        (a) The Company agrees to indemnify and hold harmless each Holder and
his representatives and agents (an "Indemnified Person"), from and against any
and all losses, claims, damages, liabilities and judgments caused by any untrue
statement or alleged untrue statement of a material fact contained in the Shelf
Registration Statement, Prospectus or form of Prospectus or in any amendment or
supplement thereto or in any preliminary Prospectus, or caused by any omission
or alleged omission to state therein a material fact required to be stated
therein or necessary in order to make the statements therein, in the case of any
Prospectus or form of Prospectus or supplement thereto, in the light of the
circumstances under which they were made, not misleading, except insofar as such
losses, claims, damages, liabilities or judgments are caused by any such untrue
statement or omission or alleged untrue statement or omission based upon
information relating to any Indemnified Person furnished to the Company by or on
behalf of such Indemnified Person; provided that the foregoing indemnity with
respect to any preliminary Prospectus shall not inure to the benefit of any
Indemnified Person from whom the Person asserting such losses, claims, damages,
liabilities and judgments purchased securities if such untrue statement or
omission or alleged untrue statement or omission made in such preliminary
Prospectus is eliminated or remedied in the Prospectus and a copy of the
Prospectus shall not have been furnished to such Person in a timely manner
provided such failure is not as a result of an action or inaction on the part of
the Indemnifying Person.

        (b) In case any action shall be brought against any Indemnified Person,
based upon the Shelf Registration Statement or any such Prospectus or any
amendment or supplement thereto and with respect to which indemnity may be
sought against the Company, such Indemnified Person shall promptly notify the
Company in writing and the Company shall assume the defense thereof, including
the employment of counsel reasonably satisfactory to such Indemnified Person and
payment of all fees and expenses. Any Indemnified Person shall have the right to
employ separate counsel in any such action and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
such Indemnified Person, unless (i) the employment of such counsel shall have
been specifically authorized in writing by the Company, (ii) the Company shall
have failed to assume the defense and employ counsel for the Indemnified Parties
or (iii) the named parties to any such action (including any impleaded parties)
include both such Indemnified Person and the Company and such Indemnified Person
shall have been advised by counsel that there may be one or more legal defenses
available to it which are different from or additional to those available to the
Company (in which case the Company shall not have the right to assume the
defense of such action on behalf of such Indemnified Person), provided, however,
that the Company shall not, in connection with any such action or separate but
substantially similar or related actions in the same jurisdiction arising out of
the same general allegations or circumstances, be liable for the fees and
expenses of more than one separate firm of attorneys (in addition to any local
counsel) for all such Indemnified Persons, which firm shall be designated in
writing by such Indemnified Persons; and provided, however, that all such fees
and expenses shall 


                                       8
<PAGE>   10
be reimbursed as they are incurred. The Company shall not be liable for any
settlement of any such action effected without its written consent but if
settled with the written consent of the Company, the Company agrees to indemnify
and hold harmless any Indemnified Person from and against any loss or liability
by reason of such settlement. No indemnifying party shall, without the prior
written consent of the indemnified party, effect any settlement of any pending
or threatened proceeding in respect of which any indemnified party is or could
have been a party and indemnity could have been sought hereunder by such
indemnified party, unless such settlement includes an unconditional release of
such indemnified party from all liability on claims that are the subject matter
of such proceeding.

        (c) In connection with the Shelf Registration Statement, each Holder
participating in such Shelf Registration Statement agrees, severally and not
jointly, to indemnify and hold harmless the Company, its directors, its officers
and any Person controlling the Company within the meaning of Section 15 of the
Securities Act or Section 20 of the Exchange Act to the same extent as the
foregoing indemnity from the Company to each Indemnified Person but only with
reference to information relating to such Indemnified Person furnished by or on
behalf of such Indemnified Person. In case any action shall be brought against
the Company, any of its directors, any such officer or any Person controlling
the Company based on such Shelf Registration Statement and in respect of which
indemnity may be sought against any Indemnified Person, the Indemnified Person
shall have the rights and duties given to the Company (except that if the
Company shall have assumed the defense thereof, such Indemnified Person shall
not be required to do so, but may employ separate counsel therein and
participate in the defense thereof but the fees and expenses of such counsel
shall be at the expense of such Indemnified Person), and the Company, its
directors, any such officers and any Person controlling the Company shall have
the rights and duties specified for Indemnified Persons in Section 5(b) hereof.

        (d) If the indemnification provided for in this Section 5 is unavailable
to an indemnified party in respect of any losses, claims, damages, liabilities
or judgments referred to therein, then each indemnifying party, in lieu of
indemnifying such indemnified party, shall contribute to the amount paid or
payable by such indemnified party as a result of such losses, claim, damages,
liabilities and judgments (i) in such proportion as is appropriate to reflect
the relative benefits received by the Company on the one hand and each
Indemnified Person on the other hand from the offering of the Restricted
Securities or (ii) if the allocation provided by clause (i) 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 the Company and each such Indemnified Person in connection with the
statements or omissions which resulted in such losses, claims, damages,
liabilities or judgments, as well as any other relevant equitable
considerations. The relative fault of the Company and each such Indemnified
Person shall be determined by reference to, among other things, whether the
untrue or alleged untrue statement of a material fact or the omission to state a
material fact relates to information supplied by the Company or such Indemnified
Person and the parties' relative intent, knowledge, access to information and
opportunity to correct or prevent such statement or omission.

        The Company and the Holders agree that it would not be just and
equitable if contribution pursuant to this Section 5(d) were determined by pro
rata allocation (even if the Indemnified Persons were treated as one entity for
such purpose) or by any other method of allocation which 


                                       9
<PAGE>   11
does not take account of the equitable considerations referred to in the
immediately preceding paragraph. The amount paid or payable by an indemnified
party as a result of the losses, claims, damages, liabilities or judgments
referred to in the immediately preceding paragraph shall be deemed to include,
subject to the limitations set forth above, 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
Section 5, no Indemnified Person shall be required to contribute any amount in
excess of the amount by which the total net proceeds received by it in
connection with the sale of the Restricted Securities pursuant to this Agreement
exceeds the amount of any damages which such Indemnified Person has otherwise
been required to pay by reason of such untrue or alleged untrue statement or
omission or alleged omission. No Person guilty of fraudulent misrepresentation
(within the meaning of Section 11(f) of the Securities Act) shall be entitled to
contribution from any Person who was not guilty of such fraudulent
misrepresentation. The Indemnified Persons' obligations to contribute pursuant
to this Section 5(d) are several in proportion to the respective amount of
Restricted Securities included in any such Shelf Registration Statement by each
Indemnified Person and not joint.

6.      Rule 144

        The Company shall use its reasonable best efforts to file the reports
required to be filed by it under the Securities Act and the Exchange Act in a
timely manner and, if at any time it is not required to file such reports but in
the past had been required to or did file such reports, it will, upon the
request of any Holder, make available other information as required by, and so
long as necessary to permit, sales of its Restricted Securities pursuant to Rule
144.

7.      Standstill Request.

        In connection with any Shelf Registration Statement filed pursuant to
this Agreement, the Holders, and each of them, agree to refrain from selling
Restricted Securities pursuant to such Shelf Registration Statement during any
period in which the Company is engaged in an offering of securities or during
which the securities laws or other regulatory requirements or the reasonable
requirements of investment bankers to the Company make such action necessary or
appropriate from the standpoint of the Company; provided, however, that each
Holder's ability to sell its Restricted Securities under this Agreement shall
not be suspended for more than (A) 10 consecutive trading days in any calendar
year or 30 days in aggregate during any calendar year (pro-rated for calendar
year 1997) (in each case other than as specified in clauses (B) and (C) below),
including without limitation by reason of any suspension or stop order with
respect to the Registration Statement or the fact that an event (other than an
event described in clauses (B) or (C) below) has occurred as a result of which
the Prospectus (including any supplements thereto) included in such Registration
Statement then in effect contains any untrue statements of material fact or
omits 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, but other than in connection with a Permitted Public
Offering (as hereinafter defined), (B) 45 consecutive days or 90 days in the
aggregate during any calendar year (pro-rated for calendar year 1997), in
connection with one or more material acquisitions by the Company, which
acquisitions require the Company to present the financial statements of the
acquired business in accordance with Rule 3-05 of Regulation S-X under the

accordance with Rule 11-01 of Regulation S-X under the Exchange Act, which
presentation requirement shall result in a Holder's inability to use the
Registration Statement to offer and sell Restricted Securities, or (C) 10 days
prior to, and 30 days subsequent to the pricing of each Permitted Public
Offering, but not in excess of 80 days in the aggregate in any calendar year
(pro-rated for calendar year 1997). A "Permitted Public Offering" shall mean a
bona fide public offering of shares of Common Stock which raises gross proceeds
of at least $25 million. In such event, the Company will notify Holders in
writing (a) at least 10 days before the effective date of any such offering, or
(b) promptly upon a determination by the Company as to the securities law or
regulatory or other requirement prompting the invoking of this Section 7. Should
it be necessary to terminate the effectiveness of any Shelf Registration
Statement or blue sky qualification filed hereunder for the period described in
this Section 7, as soon as practicable thereafter, the Company shall take all
appropriate steps, at its own expense, to have the Shelf Registration Statement,
or any substitute registration made necessary by the prior termination, declared
effective by the Commission and qualify all Shares under the "blue sky" or other
securities laws of all states in which the Shares were previously qualified.

8.      Miscellaneous

        (a) Remedies. In the event of a breach by the Company, or by a Holder of
any of their obligations under this Agreement, each Holder or the Company, in
addition to being entitled to exercise all rights granted by law, including
recovery of damages, will be entitled to specific performance of its rights
under this Agreement. The Company and each Holder agrees that monetary damages
would not be adequate compensation for any loss incurred by reason of a breach
by it of any of the provisions of this Agreement and hereby further agrees that,
in the event of any action for specific performance in respect of such breach,
it shall waive the defense that a remedy at law would be adequate.

        (b) No Piggyback on Registrations. After the date hereof, the Company
shall not grant to any of its security holders (other than the Holders) the
right to include any of its securities in the Shelf Registration Statement other
than Restricted Securities.

        (c) Amendments and Waivers. The provisions of this Agreement, including
the provisions of this sentence, may not be amended, modified or supplemented,
and waivers or consents to departures from the provisions hereof may not be
