     The Business section and other parts of this Annual Report on Form 10-K
contain forward-looking statements that involve risks or uncertainties.  The
Company's actual results may differ significantly from the results discussed in
the forward-looking statements.  Factors that might cause such a difference

"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Factors Affecting Future Operating Results."

ITEM 1. BUSINESS.

     Physicians Quality Care, Inc., a Delaware corporation ("PQC" or the
"Company"), was incorporated in March 1995, and provides practice management
services for multi-specialty medical practice groups. The Company's objective is
to establish networks of primary and specialty care physicians and related
diagnostic and therapeutic support services which can provide comprehensive
healthcare services in targeted geographic areas.

     PQC's strategy has four central elements:  (i) developing economies of
scale in support services for physician practices (i.e., administrative, billing
and clerical staff) and managed care contracts and geographic penetration by
affiliating with large numbers of qualified physicians in targeted geographic
areas; (ii) assisting the affiliated practices in providing cost-effective
healthcare to special populations; (iii) building comprehensive local healthcare
networks by developing contractual or strategic relationships with providers of
ancillary services such as home healthcare and weight and health management; and
(iv) improving the financial performance of affiliated physician's practices by
seeking to maximize the value of each physician encounter. To date, the Company
has focused upon developing its presence in western Massachusetts, northern
Connecticut, Maryland and Atlanta. The Company believes that once the Company
has developed a large base of affiliated physicians its strategy will enable the
Company to generate increased demand for the services and capabilities of its
affiliated physicians, treat patients in lower cost settings and negotiate
favorable managed care contracts. The Company intends to achieve growth through
the recruitment of additional physicians, the expansion of managed care
relationships and the development of contractual or strategic relationships with
providers of ancillary services.

     The core of PQC's proposed integrated healthcare delivery system is its
affiliation with groups of physicians who enter into long-term management
agreements with the Company. The Company assumes responsibility for non-medical
aspects of an affiliated physician's practice and focuses its efforts on seeking
to increase revenues and improve operating margins, implementing management
information systems and negotiating managed care contracts. The physicians
remain responsible for, among other things, the medical, professional and
ethical aspects of their practices. By affiliating with the Company, physicians
have increased opportunity to access capital, continue to participate in the
profitability of their individual practices and, through stock ownership, share
a financial interest in the overall performance of the Company.

Industry Overview
- -----------------

     Traditionally, health insurance plans reimbursed providers on a fee-for-
service basis, a system that offered very little incentive for efficiency. In
recent years, the healthcare industry has undergone significant changes as both
the private and public sectors seek to slow spending growth. Since the early
1980s, much of the healthcare coverage in the U.S. has shifted to managed care
systems which offer cost savings in exchange for limiting the utilization of
services. Moreover, there has been a shift to prepaid insurance plans that offer
comprehensive healthcare services to enrollees and pay providers a fixed,
prepaid monthly premium. The most prevalent of these prepaid health insurance
alternatives is the health maintenance organization ("HMO"). To remain
competitive, HMOs and other similar payors seek to align themselves with the
most cost- and service-effective providers, generally channeling patient volume
to such providers.

     In the managed care environment, doctors must contract or affiliate with
leading insurers or healthcare networks in their practice area. The third-party
payors rely on primary care physicians to play a "gatekeeping" role and to make
important medical decisions for the patient. Many payors look to share the risk
of providing services through capitation arrangements which provide for fixed
payments for patient care over a specified period of time. In general, capitated
contracts pay a flat dollar amount per enrollee in exchange for the physician's
obligation to provide or arrange for the provision of a broad range of
healthcare services (including inpatient care) to the enrollee. A significant
difference between a capitated contract and traditional managed care contracts
is that the physician is sometimes responsible for both professional physician
services and many other healthcare services, e.g., hospital, laboratory, nursing
home and home health. The physician is not only the "gatekeeper" for enrollees,
but is also financially at risk for over-utilization and for the actuarial risk
that certain patients may consume significantly more healthcare resources than
average for patients of similar age and sex (such patients being referred to as
"high risk patients"). Although physicians often purchase reinsurance to cover
some of the actuarial risk associated with high risk patients, such insurance
typically does not apply with respect to the risk of over-utilization until a
relatively high level of aggregate claims has been experienced. If over-
utilization occurs with respect to a given physician's enrollees (or if the
physician's panel of enrollees includes a disproportionate share of high risk
patients not covered by reinsurance), the physician typically is penalized by
failing to receive some or all of the physician's compensation under the
contract that is contingent upon the attainment of negotiated financial targets,
or the physician may be required to reimburse the payor for excess costs. In
addition, a physician may be liable for over-utilization by other physicians in
the same "risk pool" and for utilization of ancillary, inpatient hospital and
other services when the physician has agreed contractually to manage the use of
those services. Under this payment system, primary care physicians have
important economic incentives to reduce costs by ensuring the efficient
utilization of other providers of care, shifting care to outpatient settings
where feasible, monitoring the progress of patients throughout the course of
treatment and encouraging preventive healthcare.

                                      -2-
<PAGE>
 
     In this environment, physicians are facing reimbursement pressures, greater
administrative burdens, increasing financial responsibility for the risk of
patient care, and a shift in demand from specialty to primary care. In addition,
legislative changes have substantially limited a physician's ability to maintain
an ownership interest in entities that provide ancillary services such as
outpatient laboratories, infusion centers and diagnostic and rehabilitation
facilities. These factors have all contributed to a moderation, if not
reduction, in the growth of many physicians' incomes. With greater oversight by
third-party payors, physicians are also facing a decrease in control over
medical decisions and the administration of their practices.

     In response to these changes in the marketplace, many physicians are
joining together to maintain clinical autonomy, create greater negotiating
leverage vis-a-vis HMOs and other third party payors and reduce escalating
administrative costs. Physicians also are increasingly abandoning traditional
private practice which typically has higher operating costs and little
purchasing power with suppliers and must spread overhead over a relatively small
revenue base in favor of affiliations with larger organizations. Three basic
groups have emerged as managers of physician practices each of which encompasses
several variations in format: hospitals, which may employ physicians directly or
provide support through a management services organization ("MSO"); insurance
companies, which may employ physicians directly through HMOs or may provide
management services through an affiliated MSO; and independent, investor-owned
physician practice management companies.

Company Strategy
- ----------------

     The Company believes that physician practice management companies ("PPMs"),
such as PQC, offer physicians significant advantages over other alternatives in
the industry consolidation. PPMs provide physicians with improved practice
management and an opportunity to participate in the growth of the PPM through
stock ownership while maintaining control over medical decisions. The physician
market is currently highly fragmented, and PPMs and other organizations
providing physicians with management alternatives have thus far captured only a
small portion of this potential market.

     In addition, the Company believes that because physicians can serve as
gatekeepers for patient care, they can exercise direct control over healthcare
spending and should be in a position to share in the savings generated by the
cost containment practices they adopt. For a fee or a percentage of the group's
earnings, a PPM provides physician groups with administrative and practice
management services that are needed for a physician group to realize these cost
savings and to seek to optimize contractual relationships with managed care
organizations, thus retaining some or most of the cost savings so generated.

     The central elements of the Company's strategy are to develop long-term
affiliations with physicians, focus on cost effective healthcare delivery to
special populations, and build comprehensive local healthcare networks. To date,
the Company has focused upon developing a network of affiliated physicians. The
Company believes that its strategy will enable the 

                                      -3-
<PAGE>
 
Company to generate increased demand for the services and capabilities of its
affiliated physicians, treat patients in lower cost settings and negotiate
favorable managed care contracts.

     Develop long-term affiliations with physicians. PQC seeks to affiliate with
physicians in solo or group practices by entering into contractual arrangements
pursuant to which PQC, or a professional corporation or professional association
affiliated with PQC, assumes management of non-medical aspects of the practices
(an "Affiliated Group"). Upon affiliation, PQC seeks to provide the physicians
with, among other things, increased opportunity to access capital, management
experience, improved information systems and increased opportunity to
participate in favorable managed care contracts. The Company intends to assist
affiliated physicians in improving clinical outcomes and seeks to keep medical
costs down by merging physicians into Affiliated Groups. The Company's structure
allows physicians to continue to practice in their existing locations with no
disruption to patient flow patterns while providing access to coordinated
ancillary services. By affiliating with PQC, physicians, through the revenue
sharing provisions of their employment agreements and the Services Agreements
between the Affiliated Group and PQC, continue to participate in the
profitability of their individual practices and, through stock ownership, share
a financial interest in the overall performance of the Company. Physicians
constitute a majority of the Board of the Directors of PQC and all local
advisory boards, which control such decisions as clinical protocols and
utilization review, payor relations and the addition of ancillary services.

     Balance of primary care physicians and specialists. PQC believes that a
successful system should be balanced between primary care physicians and
specialists to provide efficient coordination and utilization of the appropriate
levels of care, and PQC intends to seek to develop this balance in the physician
groups with which it affiliates. Of the 185 physicians affiliated with the
Company at December 31, 1997, 128 are engaged in primary care practices and 57
are engaged in specialist practices. The Company believes the industry trend
toward integrated delivery systems will result in an increasing demand for
primary care physicians because a higher degree of coordination of care and
risk-sharing will be required than that which can be achieved in a system
controlled by specialists. The Company's strategy is to have the primary care
physician serve as the central manager in the patient system and to develop
effective coordination between specialists and the primary care physicians
within its network.

     Focus on special populations. PQC believes that the management of
healthcare costs for certain populations provides significant opportunities that
are not being addressed in the marketplace. The Company believes that special
populations, including the elderly, the disabled and those with debilitating
chronic or high-cost, complex diseases represent a minority of the population
but account for a disproportionately high percentage of the healthcare costs in
the United States due to the significantly greater need of such patients for
medical care compared to the population as a whole. The Company believes that a
significant portion of these costs can be avoided with effective case
management, use of information systems, and coordinated use of the full
continuum of healthcare. At present, a relatively 

                                      -4-
<PAGE>
 
small percentage of these patients are enrolled under capitated contracts.
However, the Company believes that the cost pressures that fostered the
development of managed care for other segments of the population should have an
even more significant impact on the rapid development of managed care for such
patients. Through affiliation with physicians and academic experts who
specialize in geriatrics and medical conditions that disproportionately affect
these population segments, effective use of case management techniques designed
specifically for such populations, and management information systems, the
Company believes that its affiliated physicians should be able to manage cost
effectively the risks of providing care to these populations on a capitated
basis.

     Improved medical quality and performance. Over time, the Company intends
that its affiliated physicians will devise medical protocols and the Company
will perform outcome analyses, such that the most effective medical practices in
each network can be shared across physician groups. The Company is in the
process of establishing a quality assurance program that will incorporate peer
review, self-critiquing mechanisms, patient satisfaction surveys, continuing
medical staff development and regular continuing medical education seminars.
Once a large base of affiliated physicians at Affiliated Groups is established,
medical directors of each local care network will participate in the Company's
National Medical Advisory Board that will meet regularly to establish and review
medical standards, policies and procedures for all physicians affiliated with
the Company.

Affiliation Structure
- ---------------------

     General affiliation model. Although the details of each affiliation
transaction may differ, the Company has developed a general affiliation model
designed to capture the benefits of integration while preserving significant
physician autonomy (the "General Affiliation Model"). In the General Affiliation
Model, physicians initially affiliating with the Company in each geographic area
who will become stockholders of the Company transfer their practices by mergers
or asset sales to an Affiliated Group, a professional corporation ("PC") or
professional association ("PA") permitted to practice medicine under applicable
law. These physicians, along with other physicians in that geographic area who
subsequently become part of an Affiliated Group and become stockholders of the
Company (the "Stockholder Physicians"), execute an Employment Agreement with the
Affiliated Group at the time that they transfer their practice assets. The
Affiliated Group, in turn, enters into a Services Agreement, generally for
periods up to 40 years, with the Company pursuant to which the Company agrees to
provide the physicians in the Affiliated Group with comprehensive management
services in exchange for a fee. As consideration for transferring their
practices to and becoming employed by the Affiliated Group, Stockholder
Physicians receive shares of the Company's Class A Common Stock, $.01 par value
per share (the "Class A Common Stock"), and in some cases cash, the amount of
which is negotiated on an individual basis between each Stockholder Physician
and the Company. Physicians who are not stockholders of the Company may also be
employed by the Affiliated Group.

                                      -5-
<PAGE>
 
     The factors that the Company considers in selecting a physician or a
physician group for affiliation include the location of the practice, whether
the practice can be successfully integrated into an Affiliated Group, the
ability of the Company to assist the physician to increase billings and control
costs, the size of the practices, the compensation sought by the physician or
physician group, the nature of the physician's practice and the reputation of
the physician in the medical community.

     All of the outstanding capital stock of each Affiliated Group is held by a
Stockholder Physician designated by the Company (the "Affiliated Group
Stockholder"). At the time of the affiliation, the Affiliated Group Stockholder
enters into an agreement (the "Designation Agreement") with the Company and the
Affiliated Group pursuant to which he or she agrees to consult with the Company
in voting the stock of the Affiliated Group, agrees to transfer the stock of the
Affiliated Group without consideration to another licensed physician at the
direction of the Company and agrees to pay over to the Company any dividend or
distribution on the stock received from the Affiliated Group. The Designation
Agreement also provides that the stock of the Affiliated Group is automatically
transferred at the direction of the Company in the event that the Affiliated
Group Stockholder attempts to transfer it to a third party. The Designation
Agreement provides, however, that the Affiliated Group Stockholder is not
required to consult with the Company as to matters requiring the exercise of
professional medical judgment.

     The Employment Agreements contain certain restrictive covenants, including
covenants relating to noncompetition, confidentiality and nonsolicitation of
employees. Pursuant to these restrictive covenants, the Stockholder Physicians
agree, during the term of the employment agreement and for a one year period
thereafter, not to establish, operate or provide medical services in a specified
geographic region, subject to certain limited exceptions. In addition, the
Stockholder Physicians agree during the employment agreement and for a two year
period thereafter not to provide certain other services related to the practice
of medicine in the geographic region and not to solicit any employee or patients
of the Affiliated Group. Under current state laws and judicial decisions that
restrict the enforcement of non-competition agreements against physicians on
public policy grounds, the Company has no or limited ability to enforce the
covenants not to compete. Each Employment Agreement generally is terminable by
the Affiliated Group with respect to any individual Stockholder Physician upon
the death or disability of such Stockholder Physician or upon the occurrence of
certain events that either interfere with the ability of such Stockholder
Physician to practice medicine or significantly diminish the value of such
Stockholder Physician's affiliation to the Affiliated Group. Each Stockholder
Physician may terminate his or her Employment Agreement under certain
circumstances, including without cause upon six months notice to the Affiliated
Group.  The Employment Agreements also contain terms permitting or requiring a
Stockholder Physician upon termination after certain material breaches of the
Affiliated Group's or the Company's obligations under the employment agreement
or the Services Agreement between PQC and the Affiliated Group, to repurchase
from the Affiliated Group the restrictive covenants and his or her practice
assets (i.e., office and examination equipment, in certain cases the lease for
premises at which the physician practices, patient lists and 

                                      -6-
<PAGE>
 
records, and third party payor contracts) upon termination of employment. The
terms of such repurchase provision may not permit the Company to fully recover
its affiliation payments to the physician or reflect the cost of affiliation
transactions at the time of termination. To date, no Stockholder Physician has
terminated an employment agreement or repurchased any practice assets.

     Pursuant to the Services Agreement, the Company provides (or arranges for
the provision of) a comprehensive package of services to the Affiliated Group
and its physicians, including offices and facilities, equipment, nursing and
other non-physician professional support, administrative personnel, information
systems, comprehensive professional liability insurance and general management
and financial advisory services. The Company, on behalf of the physicians in the
Affiliated Group, supervises the billing of all patients, insurance companies
and third-party payors and negotiates all contracts and relationships with
payors. The physicians remain responsible for, among other things, the medical,
professional and ethical aspects of their practices.

     Generally under a Services Agreement, revenue from patient care is used to
pay practice expenses and a fee to PQC for its services and to fund one or more
pools from which physician compensation is paid (each a "Compensation Pool").
The basis for such allocation is negotiated separately with each group of
affiliating physicians.  Because compensation of Stockholder Physicians is a
function of many factors including the financial performance of such physicians,
neither the Company nor an Affiliated Group can guarantee that a Stockholder
Physician will receive any minimum level of compensation, and the Stockholder
Physicians are not entitled to any compensation other than their allocated share
of the Compensation Pool. The Compensation Pool is initially allocated to the
Stockholder Physicians until each physician has received a pre-agreed draw. Any
amount remaining in the Compensation Pool is allocated among the Stockholder
Physicians as determined by a Compensation Committee appointed by the
Physicians.

     The Company believes that its General Affiliation Model offers a number of
advantages.  For example, physicians remain in their pre-affiliation locations,
offering their patients the continuity and convenience of decentralized offices.
At the same time, laboratory and administrative services generally are provided
on a centralized basis, allowing the Affiliated Groups to achieve economies of
scale in purchasing and other administrative efficiencies.  Moreover, the
Company believes that as it completes its initial affiliation transactions in
particular geographic markets, Affiliated Groups will provide it with both a
visible business presence and a corporate framework for securing additional
affiliations with physicians in those markets.

     The Company also believes that the decision making structure that it
establishes in connection with each Affiliated Group facilitates information
sharing and cooperation between the affiliated physicians and the Company. Each
Affiliated Group maintains its own policy making structure, including a Joint
Policy Board and a Medical Advisory Board. The Joint Policy Board is charged
with, among other things, developing certain management and 

                                      -7-
<PAGE>
 
administrative policies for the Affiliated Group, approving operating and
capital expenditure budgets, establishing fee schedules for services provided by
the Affiliated Group, approving the establishment of managed care contracts and
determining of the number and type of physicians required for the operation of
the Affiliated Group. Certain decisions that may have a material impact upon the
business, results of operation or financial condition of the Affiliated Group
must also be approved by the Affiliated Group Stockholder. The current Joint
Policy Boards are comprised of: the President of the Affiliated Group (selected
by the Affiliated Group Stockholder from physicians nominated by the Stockholder
Physicians), and an equal number of members selected by the Company and the
physician stockholders. The Medical Advisory Board, which is responsible for
providing medical input on managed care contracting by the Affiliated Group and
leading the development and dissemination of medical protocols among the
physicians, consists of the Medical Director of the Affiliated Group (selected
by the Affiliated Group Stockholder from physicians nominated by the Stockholder
Physicians) and other physicians elected by the Stockholder Physicians.

     Although the Affiliated Groups in the Springfield, Massachusetts area and
the greater Baltimore-Annapolis, Maryland generally track the General
Affiliation Model, the Company may depart to some extent or significantly from
it or pursue an altogether different approach in completing future physician
affiliations.

     The Springfield Affiliated Group.  The Company has entered into affiliation
transactions with nine medical practices located in western Massachusetts,
consisting at December 31, 1997 of a total of 42 physicians, 35 of whom are
stockholders in the Company (the "Springfield Stockholder Physicians") and 7 of
whom are employed by the Springfield Affiliated Group as employees (the
"Springfield Affiliated Group").  Twenty-nine of the physicians are engaged in
primary care practices, including two physicians with pediatric practices.
Thirteen of the physicians are engaged in specialist practices, including
pulmonology, cardiology, oncology/hematology, infectious disease, rheumatology
and gastroenterology.

     Consistent with the General Affiliation Model, the Springfield Stockholder
Physicians, or the professional corporations and other entities with whom they
were affiliated, merged or sold their practice assets to the Springfield
Affiliated Group in exchange for an aggregate of approximately 3,164,738 shares
of Class A Common Stock of the Company and approximately $4.1 million in cash.
The 29 initial Stockholder Physicians entered into a three-year employment
agreement with the Springfield Affiliated Group, pursuant to which each
physician also received options to purchase 2,500 shares of Class A Common Stock
of PQC at an exercise price of $2.50 per share. The options expire on the
earlier of termination of employment or three years from commencement of
employment. The Physicians who subsequently affiliated with the Springfield
Affiliated Group entered into ten-year employment agreements with the
Springfield Affiliated Group. Four of these Springfield Physician Stockholders
each received options to purchase 37,500 shares of Class A Common Stock at an
exercise price of $1.00 per share which options are subject to certain vesting
conditions. Up to an additional $2.15 million, payable in Class A Common Stock
at $2.50 per share, was 

                                      -8-
<PAGE>
 
available to be paid to certain physicians if certain revenue goals were met.
During 1997, $2.1 million of additional consideration was accrued based upon the
achievements of these goals and will be paid during 1998. The Springfield
Affiliated Group in turn entered into a 40-year services agreement with the
Company pursuant to which the Company (on behalf of the Springfield Affiliated
Group) agreed to provide management services to the Springfield Affiliated Group
physicians.

     Under the Employment Agreements with the twenty-nine initial Springfield
Stockholder Physicians, revenues from patient care remaining after payment of
operating expenses, including expenses of the Springfield Affiliated Group
("Gross Margin") are allocated first between the Springfield Affiliated Group's
Compensation Pool (the "Springfield Compensation Pool") and the Springfield
Affiliated Group in a 95%/5% proportion until 95% of the base compensation of
the Springfield Stockholder Physicians is achieved, then to payment of certain
non-operating expenses, and then 80% to the Springfield Affiliated Group and 20%
to the Springfield Compensation Pool until the Springfield Affiliated Group has
been allocated $1.5 million, with any remaining Gross Margin being divided
evenly between the Springfield Affiliated Group and the Springfield Compensation
Pool. Under the Employment Agreements with the Springfield Stockholder
Physicians who subsequently affiliated with the Springfield Affiliate Group any
Gross Margin attributable to these physicians are allocated between the
Springfield Compensation Pool and the Springfield Affiliated Group in a 80%/20%
proportion until the physicians receive 80% of their base compensation, and then
to payment of certain non-operating expenses attributable to the Springfield
Affiliated Group, with any remaining Gross Margin being divided evenly between
the Springfield Compensation Pool and the Springfield Affiliated Group. The
allocation of Gross Margin to the Springfield Compensation Pool is calculated
separately for each fiscal period. If the Gross Margin for any such period is
negative, such negative amount constitutes an operating expense in the next
fiscal period. Pursuant to the Springfield Services Agreement, all amounts
allocated to the Springfield Affiliated Group in any fiscal period are remitted
to the Company.

     On March 1, 1999, the Springfield Affiliated Group (on behalf of the
Company) or a majority of the Springfield Shareholder Physicians may amend the
financial arrangements, effective as of August 30, 1999, such that the economic
terms of the Springfield Stockholder Physicians' employment agreements, taken as
a whole (and giving effect to any payments or other compensation received by the
Springfield Stockholder Physicians in connection with their affiliation), are
adjusted to reflect the terms being entered into by independent third parties
for similar affiliation and employment relationships at that time.

     The Flagship Affiliated Group. On December 11, 1996, pursuant to
affiliation transactions with the Company, 15 existing professional practices
located in the greater Baltimore-Annapolis, Maryland area, consisting of a total
of 55 physicians, transferred their practice assets to and became employed by
Flagship Health P.A., a Maryland professional association (the "Flagship
Affiliated Group"). In exchange for such affiliation, the physicians received a
combination of approximately $2.7 million in cash and 6,842,675 shares of 

                                      -9-
<PAGE>
 
Class A Common Stock (the "Initial Flagship Affiliation"). On December 1, 1997,
Clinical Associates, P.A., a Maryland professional association ("Clinical
Associates"), which also had practices in the Baltimore area, was combined with
the Flagship Affiliated Group. The stockholders of Clinical Associates received
approximately $3.0 million in cash and 4,800,000 shares of Class A Common Stock.

     As of December 31, 1997, the Flagship Affiliated Group employed 143
physicians and 16 non-physician medical professional, of which 113 are
stockholders of the Company and employees of the Flagship Affiliated Group (the
"Flagship Stockholder Physicians") and 30 are employees of the Flagship
Affiliated Group. Of the physicians employed by the Flagship Affiliated Group,
99 are primary care or pediatric physicians and 44 are specialists.  The
specialist practices include pulmonology, cardiology, oncology/hematology,
infectious disease, rheumatology, gastroenterology, neurology, dermatology,
endocrinology, immunology, neurology, psychiatry, obstetrics/gynecology,
ophthalmology, orthopedics, otolaryngology, plastic surgery, urology, general
surgery and vascular surgery. The Flagship Affiliated Group leases 28 practice
locations in Maryland, some of which are leased from the Flagship Stockholder
Physicians.

     In order to effectuate the Flagship Affiliation, the Flagship Stockholder
Physicians, or the professional associations, business corporations and limited
liability partnerships with whom they were affiliated, transferred their
practice assets to the Flagship Affiliated Group by merger or by sale of assets.
The Company entered into a 40-year management services agreement with the
Flagship Affiliated Group (the "Flagship Services Agreement"), which entered
into Employment Agreements with each Flagship Stockholder Physician. In
addition, the Company entered into an agreement with the Flagship Affiliated
Group pursuant to which the Company agreed to grant options to purchase, subject
to certain conditions, up to 400,000 shares of Class A Common Stock to the
Flagship Stockholder Physicians.

     Pursuant to the Flagship Services Agreement and the Employment Agreements
with the Flagship Stockholder Physicians who initially affiliated with the
Flagship Affiliated Group (the "Initial Flagship Affiliated Physicians"),
revenues from patient services remaining after payment of third- party operating
expenses ("Net Margin") is allocated between the Flagship Stockholder
Physicians' Compensation Pool (the "Initial Flagship Compensation Pool") and
reimbursement of the Company's direct expenses relating to the Flagship
Affiliated Group, based on a ratio of such budgeted compensation to such
budgeted expenses. Once both the Company's direct expenses and the aggregate
base physician compensation have been fully satisfied, any remaining Net Margin
will be divided evenly between the Company and the Initial Flagship Compensation
Pool.

     The method for determining PQC's management fee and the compensation of the
Clinical Associates physicians differs from the model used in the Springfield
Affiliated Group and with the original Flagship physicians. Instead of a sharing
of gross margin after practice expenses, PQC is entitled to a percentage of
billings, net of uncollectible amounts and discounts ("Net Adjusted Billings").
The revenue splitting arrangements for the Clinical 

                                      -10-
<PAGE>
 
Associates physicians differ based upon whether the revenue is derived from an
existing specialist practice, a primary care practice, future specialist
practices and the practices of physicians without established practices. Except
as provided below, Net Adjusted Billings in excess of baseline Net Adjusted
Billings reflecting the historical level billings for such physician subject to
reductions for changes in practice patterns ("Specialist Net Adjusted Billings")
from specialist (a specialist being a physician at least 80% of whose billings
are derived from a specialist practice) practices with respect to any fiscal
year will be allocated 35% to PQC and 65% to an account established with respect
to the Clinical Associates physicians and any future physicians included in the
same compensation arrangements (the "Account") until $3 million has been
allocated between the Account and PQC; and any remaining Specialist Billings
will be allocated 20% to PQC and 80% to the Account.

     Net Adjusted Billings by primary care, OB/GYN physicians and physicians
(whether primary care or specialist) added to the compensation arrangements in
the future in excess of the agreed upon baseline Net Adjusted Billings will be
allocated 20% to PQC and 80% to the Account. With respect to any physician
recruited to join Flagship who does not have a practice that is merged into
Flagship (and to certain physicians currently affiliated with Clinical
Associates ), 20% of the Incremented Amount shall be allocated to PQC.
"Incremented Amount" means the excess, if any, of Net Adjusted Billings
attributable to such physician over an amount equal to twice the average
compensation of physicians with a similar practice in the Baltimore metropolitan
area as reported by a standardized reporting source. Any Net Adjusted Billings
attributable to such physician less (A) the amounts allocated to PQC and (B) the
compensation payable to the physician under the physician's employment agreement
shall be allocated to the Account. Any revenue not included in Net Adjusted
Billings will be allocated to the Compensation Pool to offset practice expenses,
provided that if the ratio of practice expenses to practice revenue declines
below historical levels, revenues not included in Net Adjusted Billings will be
allocated equally to PQC and the Account. Net Margin from centralized laboratory
services (which for this purpose shall mean revenue from laboratory ancillary
services less (i) direct expenses of such laboratory ancillary services and (ii)
an allocation of Flagship overhead) attributable to the Clinical Associate
physicians will be allocated 80% to PQC and 20% to the Account. Net Margin from
incremental non-laboratory ancillary services will be allocated 50% to PQC and
50% to the Account together with the current Flagship Compensation Pool.

     The amount allocated to the Account is first used to pay the practice
expenses of the physicians whose compensation is paid through the Account. Any
remaining amount in the Account with respect to any fiscal year will be
distributed to the Clinical Associates physicians as their sole source of
compensation. The allocation of such compensation among the physicians is
determined by a committee elected by, or pursuant to a formula approved by, the
Clinical Associates physicians.

     PQC expects to consider restructuring the compensation arrangements with
respect to the initial Flagship Affiliated Physicians to determine whether to
merge the two compensation arrangements. In the event that PQC elects to modify
the compensation arrangements of the 

                                      -11-
<PAGE>
 
Initial Flagship Physicians in this manner, PQC will guarantee for a two year
period (commencing on the date of such merger) that the compensation of the
Clinical Associates physicians under the combined compensation distribution
system is not less than the baseline compensation that such physicians would
have received if the compensation distribution systems are not merged.

     Until June 1, 1998, the Clinical Associate physicians have the right to
elect to receive up to an additional 2,000,000 shares of Common Stock as
consideration for their affiliation with the Flagship Affiliated Group. If the
Clinical Associate physicians elect in their sole discretion to receive such
additional Common Stock, the compensation arrangements set forth above will be
amended, so that an aggregate of $760,000 of Net Adjusted Billings (or such
proportionately reduced amount if less than 2,000,000 shares of Common Stock
shares are elected) that would otherwise be allocated to the Account with
respect to each fiscal year shall instead be allocated to PQC.

     The Agreements between PQC and the Clinical Associated Physicians include a
provision that penalizes PQC if certain revenue targets described below are not
met. Until there is no Shortfall (as defined below) or PQC completes a public
offering of the Company Common Stock at a price to the public of $9.00 or more
per share, the amount that would have been allocated to PQC pursuant to the
Services Agreement will be reduced by the Adjustment Amount and the amount that
is allocated to the Account will be increased by the Adjustment Amount.
"Shortfall" means the difference between $3.0 million and the aggregate increase
in Net Adjusted Billings over baseline Net Adjusted Billing by the specialist
physicians in Clinical Associates or who are subsequently added to the practice.
The "Adjustment Amount" is 45% of any Shortfall. Consequently, unless Net
Adjusted Billing increases by $3.0 million over historical levels, and
Adjustment Amount will be due.

     PQC has agreed with the stockholders of Clinical Associates that neither
PQC nor Flagship will merge with or into, become a subsidiary of, or sell
Flagship or all or substantially all of PQC's assets to, or grants governance
participation to, a Baltimore Health Care Entity without the approval of a
majority of the members of the Management Committee. A Baltimore Health Care
Entity means any hospital, medical group or other organization that principally
conducts its business in and derives its revenues from the delivery of
healthcare services in Maryland.

     In the event that PQC or any of its affiliates propose the establishment of
an independent provider association ("IPA") network in the Maryland Area, PQC is
required to obtain the approval of the Joint Policy Board with respect to the
structure, governance and financial arrangements of the IPA network, including
whether the Physicians in the Flagship Affiliated Group will participate in such
IPA network. PQC will be entitled to a fee of up to 10% of the aggregate revenue
of the IPA network, which fee PQC shall not be required to share with the
physicians employed by the Flagship Affiliated Group. Any residual profits of
the IPA network (in excess of the 10% fee) that are retained by PQC shall be
allocated 50% to PQC and 50% to the physicians in the Flagship Affiliated Group.

                                      -12-
<PAGE>
 
     In the event that prior to December 1, 2001, PQC has not completed an
underwritten initial public offering, the Clinical Associates physicians shall
have the right, within 45 days thereafter, to require PQC to repurchase the
Common Stock issued in the affiliation transaction with Clinical Associates at a
purchase price of $3.00 per share. PQC shall have the right to pay the purchase
price by a five (5) year non-interest bearing note. The principal payable with
respect to such note shall be reduced by the amount, if any, that the Clinical
Associates physicians' compensation between the issue date of the note and its
maturity exceeds the base compensation with respect to the Clinical Associates
physicians during that period.

     Atlanta IPA Affiliates.  The Company has acquired a 50% interest in two
related physician network management companies in Atlanta, Georgia. The two
entities, TLC Management Company, Inc. ("TLC") and Total Quality Practice
Management, Inc. ("Total Quality"), manage payor contracting for a 350-physician
network in Georgia. The network currently serves approximately 4,500 covered
lives. PQC's investment totals $5 million.  The Company believes that the
Atlanta market is attractive for the Company as it is a relatively
unconsolidated physician practice market and global capitation arrangements are
expected to become a more significant market factor.

     Future Affiliation Transactions. The Company's current primary focus is on
expanding the Springfield Affiliated Group and the Flagship Affiliated Group,
and developing additional Affiliated Groups in the eastern United States.

     The Company will determine which geographic markets to enter in the future
based upon consideration of the following factors (among others): (i) population
and economic profile, (ii) level of managed care penetration and effectiveness
of providers in coping with the managed care environment, (iii) physician
practice density, specialty composition, and average group size, (iv)
receptivity of the medical community to the Company's management philosophy, 
(v) local competition in the physician practice management business and (vi)
commercial and Medicare reimbursement rates. The Company also regularly
considers the addition of physicians on an employee, rather than a Stockholder
Physician, basis.

Governmental Regulation
- -----------------------

     As a participant in the healthcare industry, the Company's operations and
relationships, and the business and activities of its affiliated physicians,
will be subject to extensive and increasing regulation by a number of
governmental entities at the federal, state and local levels and by fiscal
intermediates appointed by various payors and other private brokers. The Company
will also be subject to laws and regulations relating to business corporations
in general. Because of the uniqueness of the structure of the relationship with
the physician groups, many aspects of the Company's business operations have not
been the subject of state or federal regulatory interpretation, and there can be
no assurance that a review of the business of the Company or its affiliated
physicians by courts or regulatory authorities will not result in a
determination that could adversely affect the operations of the Company or the

                                      -13-
<PAGE>
 
affiliated physicians. In addition, there can be no assurance that the
healthcare regulatory environment will not change so as to restrict the
Company's or the affiliated physicians' existing operations or their expansion.

     Prohibition on Corporate Practice of Medicine. The laws of most states,
including Massachusetts and Maryland, prohibit business corporations such as the
Company from practicing medicine or employing physicians to do so. The
contractual relationships the Company has entered into with the Affiliated
Groups attempt to comply with these laws. Because there is very limited judicial
or regulatory interpretation of the scope of the corporate practice of medicine
prohibition in most states, however, there can be no assurance that the
Company's contractual arrangements will be found to comply with such laws. Any
determination that the contractual relationships violate such laws could have a
material adverse effect on the Company, and there can be no assurance that the
Company would be able to restructure its arrangements on favorable terms or at
all.

     The Massachusetts Board of Registration in Medicine (the "BRM") has
proposed regulations that, if promulgated as proposed, might prohibit physicians
licensed within the Commonwealth of Massachusetts from entering into management
contracts with proprietary business entities unless a majority of the governing
board of those business entities are licensed physicians and certain other
conditions are met. The BRM also indicated that it may seek to limit
significantly the extent to which proprietary business entities may have control
or consultation rights with respect to medical decisions or business decisions
that may affect patient care, such as the amount of time each physician spends
with a patient. Extensive commentary has been filed in opposition to the
proposed regulations, and it is not known when or in what form final regulations
will be promulgated. The final regulations may have a material adverse effect on
the Company's relationship with the Springfield Affiliated Group and its ability
to operate in Massachusetts as currently contemplated. Comparable regulations
have not been proposed in Maryland, but there can be no assurance that such
regulations will not be proposed or adopted.

     Restrictions on Referrals and Fee-Splitting. In addition to prohibiting the
practice of medicine, numerous states prohibit entities such as the Company from
engaging in certain healthcare-related activities such as fee-splitting with
physicians or from making referrals to entities in which the referring physician
has an ownership interest. For example, Maryland has enacted legislation that
significantly restricts patient referrals for certain services, and requires
disclosure of ownership in businesses to which patients are referred and places
other regulations on healthcare providers. The Company has structured its
arrangements with the practices in the Flagship Affiliation to fit within the
group practice exemption contained in the Maryland act; however, investments or
contractual relationships with businesses not specifically operated by the
Flagship Affiliated Group would, in some cases, be prohibited. The Company
believes it is likely that other states will adopt similar legislation.
Accordingly, expansion of the operations of the Company to certain jurisdictions
may require it to comply with such jurisdictions' regulations which could lead
to structural and organizational 

                                      -14-
<PAGE>
 
modifications of the Company's anticipated form of relationships with physician
groups. Such changes, if any, could have an adverse effect on the Company.

     Certain provisions of the Social Security Act, commonly referred to as the
"Anti-kickback Statute," prohibit the offer or receipt of any form of
remuneration in return for the referral of Medicare or state health program
(such as Medicaid) patients, or in return for the recommendation, arrangement,
purchase, lease, or order of items or services that are covered by Medicare or
state health programs. The Anti-kickback Statute is broad in scope and has been
broadly interpreted by courts in many jurisdictions. Read literally, the statute
places at risk many customary business arrangements, potentially subjecting such
arrangements to lengthy, expensive investigations and prosecutions initiated by
federal and state governmental officials. Many states have adopted similar
prohibitions against payments intended to induce referrals of state health
program and other third-party payor patients. While the Company has attempted to
structure its contractual relationships so as to comply with the Anti-kickback
Statute, there can be no assurance that such relationships do in fact comply
with the Anti-kickback Statute given the broad wording of the statute. While the
federal government has promulgated or proposed various "safe harbor" exceptions
to the Anti-kickback Statute, the Company does not expect its operations to fit
within any of the safe harbors. Violation of the Anti-kickback Statute is a
felony, punishable by fines up to $25,000 per violation and imprisonment for up
to five years. In addition, the Department of Health and Human Services may
impose civil penalties excluding violators from participation in Medicare or
state health programs.

     Significant prohibitions against physician referrals were enacted by
Congress in the Omnibus Budget Reconciliation Act of 1993. These prohibitions,
commonly known as "Stark II," amended prior physician self-referral legislation
known as "Stark I" by dramatically enlarging the field of physician-owned or
physician-interested entities to which the referral prohibitions apply. Stark II
prohibits, subject to certain exemptions, a physician or a member of his or her
immediate family from referring Medicare or state health program patients for
"designated health services" to an entity in which the physician has an
ownership or investment interest or with which the physician has entered into a
compensation arrangement including the physician's own group practice. The
designated health services include radiology and other diagnostic services,
radiation therapy services, physical and occupational therapy services, durable
medical equipment, parenteral and enteral nutrients, equipment, and supplies,
prosthetics, orthotics, outpatient prescription drugs, home health services, and
inpatient and outpatient hospital services. The penalties for violating Stark II
include a prohibition on payment by these government programs for services
rendered pursuant to such references and civil penalties of as much as $15,000
for each violative referral and $100,000 for participation in a "circumvention
scheme." In addition, the provider may be disqualified from participating in the
Medicare and state health care programs based on the submission of a false claim
or participation in a circumventive scheme. The Company has attempted to
structure its activities in compliance with Stark I and Stark II. However, the
Stark legislation is broad and the Stark I regulations are complex and do not
provide clear guidance on how Stark II will be interpreted. A finding that the
Company or its Affiliated Groups has violated Stark could have 

                                      -15-
<PAGE>
 
a material adverse effect on the Company. In addition, future regulations or
clarification of the existing regulations could require the Company to modify
the form of its relationships with physician groups and may limit the Company's
ability to implement fully its plan for integrated care.

     Prohibition on False Claims. There are also state and federal civil and
criminal statutes imposing substantial penalties, including civil and criminal
fines and imprisonment, on healthcare providers who fraudulently or wrongfully
bill governmental or other third-party payors for healthcare services. The
federal law prohibiting false billings allows a private person to bring a civil
action in the name of the United States government for violations of its
provisions. There can be no assurance that the Company's activities will not be
challenged or scrutinized by governmental authorities. Moreover, technical
Medicare and other reimbursement rules affect the structure of physician billing
arrangements. Regulatory authorities might challenge the billing arrangements
with the Affiliated Groups and, in such event, the Company may have to modify
its relationship with physician groups. Noncompliance with such regulations may
adversely affect the operation of the Company and subject the Company and
Affiliated Groups to lost reimbursement, penalties and additional costs.

     Direct Provision of Healthcare Services. The Company plans to develop a
network of integrated healthcare services (other than acute care) in the future,
depending on market conditions. If the Company determines that it is
advantageous to provide such services through a wholly-owned subsidiary or other
controlled relationship, it is possible that one or more subsidiaries or
affiliates of the Company could become licensed providers of healthcare
services. Any such provider would have to comply with applicable regulatory
requirements. In addition, the direct provision of healthcare services by a
subsidiary or affiliate might increase the risk to the Company of regulatory or
other investigation or litigation.

     Healthcare Reform. A portion of the revenues of the Company's Affiliated
Groups is derived from payments made by governmental sponsored healthcare
programs (principally, Medicare and Medicaid). Government revenue sources are
subject to statutory and regulatory changes, administrative rulings,
interpretations of policy, determinations by fiscal intermediaries, and
government funding restrictions, all of which may materially decrease the rates
of payment and cash flow to physicians and other healthcare providers. The
federal Medicare program adopted a system of reimbursement of physician
services, known as the resource based relative value scale schedule ("RBRVS"),
which took effect in 1992 and is expected to be fully implemented by December
31, 1996. The Company expects that the RBRVS fee schedule and other future
changes in Medicare reimbursement will, in some cases, result in a reduction
from historical levels in the per patient Medicare revenue received by certain
of the Affiliated Groups with which the Company may contract, which in turn may
result in a decrease in revenues to the Company.

     In addition to current regulation, the United States Congress has
considered various types of healthcare reform, including comprehensive revisions
to the current healthcare 

                                      -16-
<PAGE>
 
system. It is uncertain what legislative proposals will be adopted in the
future, if any, or what actions federal or state legislatures or third party
payors may take in anticipation of or in response to any healthcare reform
proposals or legislation. Healthcare reform legislation adopted by Congress
could result in lower payment levels for the services of physicians managed by
the Company and lower profitability of the Affiliated Groups, which could have a
material adverse effect on the operations of the Company.

     Insurance Laws. Laws in all states regulate the business of insurance and
the operation of HMOs. Many states also regulate the establishment and operation
of networks of healthcare providers. While these laws do not generally apply to
the hiring and contracting of physicians by other healthcare providers, there
can be no assurance that regulatory authorities of the states in which the
Company operates would not apply these laws to require licensure of the
Company's operations as an insurer, as an HMO or as a provider network.

     Antitrust Laws. Because the affiliated practice groups are not subsidiaries
of the Company and thus remain separate legal entities for antitrust purposes,
they may be deemed competitors subject to a range of antitrust laws which
prohibit anti-competitive conduct, including price fixing, concerted refusals to
deal and division of market. The Company intends to comply with such state and
federal laws as they may affect its development of integrated healthcare
delivery networks, but there is no assurance that the review of the Company's
business by courts or regulatory authorities will not result in a determination
that could adversely affect the operation of the Company and its affiliated
physician groups.

Competition
- -----------

     The Company faces competition for both the recruitment and retention of
affiliated physicians. The market for affiliation with physicians is highly
competitive, and the Company expects this competition to increase. The Company
competes for physician affiliations with many other entities, some of whom have
substantially greater resources, greater name recognition and a longer operating
history than the Company and some of whom offer alternative affiliation
strategies which the Company may not be able to offer.

     The provision of physician practice management services is a highly
competitive business in which the Company will compete for contracts with
several national and many regional and local providers of such services. Certain
of the Company's competitors will have access to substantially greater resources
than the Company. Although the nature of the competition may vary, competition
is generally based on cost and quality of care.

     There can be no assurance that PQC will be able to compete effectively,
that additional competitors will not enter the market, or that such competition
will not make it more difficult to acquire the assets of multi-speciality
clinics on terms beneficial to PQC.

Employees
- ---------

     As of December 31, 1997, the Company had 43 employees and the Affiliated
Groups had 1,037 employees, including 198 physicians.

ITEM 2. PROPERTIES.

     The Company leases a 6,358 square foot facility in Waltham, Massachusetts
for its headquarters and also leases office space in Springfield, Massachusetts
and Baltimore, Maryland. The Springfield Affiliated Group leases approximately
46,000 square feet at 13 practice locations and the Flagship Affiliated Group
leases approximately 197,000 square feet at 41 practice locations. The
facilities leased by the Company and its Affiliated Groups are sufficient for
its current operations.

ITEM 3. LEGAL PROCEEDINGS.

     On June 12, 1997, Jay N. Greenberg, a founder and former executive vice
president of the Company, filed a complaint against the Company in Massachusetts
state court seeking damages of $1.4 million and a declaratory judgment that
843,750 of the shares registered in Mr. Greenberg's name (out of 1,012,500
shares of Class A Common Stock originally granted to Mr. Greenberg) have
"vested" under this Employment Agreement. The complaint involves a dispute over
whether an amendment in December 1996 to Mr. Greenberg's Employment Agreement is
valid and whether Mr. Greenberg resigned or was terminated in January 1997. The
Company maintains that the amendment was fraudulently induced based upon a
commitment by Mr. Greenberg for long-term employment with the Company and that
Mr. Greenberg resigned in January 1997. Under such facts Mr. Greenberg is
entitled to have no more than 450,000 shares of Class A Common Stock vest (and,
depending upon counterclaims that may be brought by the Company, possibly fewer)
and is entitled to no severance payment. Mr. Greenberg claims that 843,750
shares of Class A Common Stock have vested and that his employment was
terminated in January 1997 by the Company entitling him to severance payments of
$440,000. The Company is not able to predict the outcome of this litigation. No
other claims are pending against the Company.

ITEM 4. SUBMISSION OF MATTERS TO A VOTE OF SECURITY HOLDERS.

     No matters were submitted to a vote of security holders of the Company,
through solicitation of proxies or otherwise, during the last quarter of the
year ended December 31, 1997.

                                    PART II

ITEM 5. MARKET FOR REGISTRANT'S COMMON EQUITY AND RELATED STOCKHOLDER MATTERS.

     The Company did not issue or sell any equity securities during the quarter
ended December 31, 1997 that were not registered under the Securities Act of
1933, as amended.

ITEM 6. SELECTED FINANCIAL DATA.

     The following selected financial data for the Company should be read in
conjunction with the financial statements and notes thereto and "Management's
Discussion and Analysis of Financial Condition and Results of Operations"
included elsewhere in this Annual Report on Form 10K. The selected financial
data of the Company for the period from March 20, 1995 (inception) through
December 31, 1995 and for the years ended December 31, 1996 and December 31,
1997, have been derived from financial statements of the Company which have been
audited by Ernst & Young LLP, independent auditors.

ITEM 7.   MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND
          RESULTS OF OPERATIONS.

Overview
- --------

     The Company affiliates with and operates multi-specialty medical practice
groups. The first physician affiliation took place on August 30, 1996, with 32
physicians in the Springfield, Massachusetts and Enfield, Connecticut area. On
December 11, 1996, PQC consummated the affiliation with the Flagship Affiliated
Group, which consisted of 59 physicians in Baltimore and Annapolis, Maryland.
In connection with the affiliation transactions, the assets and liabilities of
the physician practices were transferred to newly formed PCs or PAs affiliated
with the Company.  Additional physicians have been subsequently added to the
Affiliated Groups.  PQC is working with these groups of physicians to improve
operating practices and to obtain managed care contracts. On October 24, 1997,
the Company also acquired a 50% interest in TLC and a 50% interest in Total
Quality.  Both companies are located in Atlanta, Georgia.  As of December 31,
1997, the Company had affiliations or IPA arrangements with the following
physicians:

     The Company's Fee under Service Agreements. For a discussion of the fee and
expense allocation arrangement between the Company and each Affiliated Group,
see "Item 1. Business - Affiliation Structure."

     Under the Company's contractual arrangements with its Affiliated Groups,
the Company can improve its management fee revenues by increasing the patient
care revenue of its Affiliated Groups, whether through improved billing and
operating efficiency, additional patient encounters or increased capitated
revenues, and controlling the expenses of Affiliated Groups. To the extent that
patient revenue increases at a greater rate than practice expenses, 

                                      -21-
<PAGE>
 
PQC's management fee will increase. Conversely, if PQC is not able to control
practice expenses or assist the Affiliated Groups in increasing patient care
revenue, PQC will earn no or only a limited management fee. Under the
arrangements with the physicians formerly associated with Clinical Associates
(which became effective on December 1, 1997) PQC earns a fee based, in part,
upon increases in billings, net of bad debts and discounts, above historical
levels, and a reduction in the percentage of revenue needed to pay practice
expenses. While this structure causes PQC's management fee not to be as
dependent upon controlling practice expenses, PQC believes that both increased
revenues and controlling costs will continue to be important factors to its
management fee growth as increased billings depend upon affiliated physicians
being motivated by competitive levels of compensation.

     The Company's and its Affiliated Groups' revenues are derived from
governmental programs, managed care payors and traditional fee-for-service
arrangements. The following table sets forth the approximate percentage of the
revenues received by the practices that were affiliated with the Company at
December 31, 1997 during the year ended December 31, 1997:

Results of Operations
- ---------------------

Year Ended December 31, 1996 Compared to Period From March 20, 1995 (Inception)
to Year Ended December 31, 1995

     From inception (March 20, 1995) through August 30, 1996, the Company was
primarily in a development and start up phase.  The first affiliation with 32
Springfield, Massachusetts physicians was completed on August 30, 1996.  Prior
to this date the Company had no revenues.  On December 11, 1996, the Company
affiliated with 59 physicians in the greater Baltimore-Annapolis, Maryland area.

     In connection with the affiliation transactions, the assets and liabilities
of the physician practices were transferred to newly formed PCs and PAs
affiliated with the Company.  The assets and liabilities of the Springfield,
Massachusetts physicians were transferred to Medical Care Partners, P.C. ("MCP")
and the physicians became employees of MCP.  The assets and liabilities of the
December 11, 1996 affiliation were transferred to Flagship Health I, P.A.
("Flagship I") and the physicians became employees of Flagship I.

     The increase in revenues of $6.0 million was more than offset by increases
in operating expenses.  The affiliation transactions resulted in the addition of
physician salaries and benefits, non-physician salaries and benefits, other
practice expenses, provision for bad 

                                      -22-
<PAGE>
 
debt and depreciation and amortization. Prior to the completion of the first
affiliation transaction the Company incurred general corporate home office
expense only.

Year Ended December 31, 1997 Compared to Year Ended December 31, 1996

     During January and February 1997, the Company affiliated with 6 physicians
in the Springfield, Massachusetts area. The assets and liabilities of the
Springfield physicians were transferred to MCP and the physicians became
employees of MCP. On December 1, 1997, the Company entered into an affiliation
agreement with a physician practice consisting of 58 physicians located in the
Baltimore/Annapolis, Maryland area. The assets and liabilities of the
Baltimore/Annapolis physicians were transferred to Flagship Health II, P.A.
("Flagship II") and the physicians became employees of Flagship II.

     The completion of the Springfield and Baltimore area affiliations resulted
in the Company having net revenues of approximately $46.0 million for the year
ended December 31, 1997 compared to approximately $6.0 million for the year
ended December 31, 1996.  The increase in revenues was primarily due to both the
number and dates of affiliation of the Springfield and Baltimore physicians.
The revenues for 1996 were generated from 32 physicians from August 30, 1996
through December 31, 1996 and one month of revenues from Flagship I physicians.
The revenues for 1997 consisted of a full year of revenues from both MCP and
Flagship I physicians as well as one month's revenues generated by the 58
Flagship II physicians.  The source of revenue in 1997 remained largely
unchanged from 1996, with fee for service payments and Medicare accounting for
approximately 83% of revenue.  Although the Company is seeking to increase its
participation in capitated managed care contracts, such agreements only amounted
for approximately 12.0% of revenue in 1997.

     During the year ended December 31, 1997 as compared to the year ended
December 31, 1996, the amounts retained by physician groups, which represents
physician salaries and benefits increased approximately $13.4 million.  The
increase is primarily due to the same factors which caused the increase in
revenues, namely that 1997 consisted of a fully year of operations for MCP and
Flagship I as compared to four months of operations and one month of operations
during 1996 for MCP and Flagship I, respectively.  In addition, the affiliation
of Flagship II on December 1, 1997 resulted in an increase of approximately
$900,000 as compared with 1996.  As a percentage of net patient service revenues
amounts retained by physician groups decreased from 36.4% in 1996 to 33.8% in
1997.  This decrease was primarily due to variances in the fee and expenses
allocation arrangements between the Company and each Affiliated Group.  See
"Item 1. Business-Affiliation Structure."

     During the year ended December 31, 1997 as compared to the year ended
December 31, 1996, nonphysician salaries and benefits, which represents salaries
and benefits for staff engaged in the physicians' practice increased
approximately $12.0 million.  Other practice expenses in 1997, which represent
primarily all non-salary and benefits expenses of physicians' practices,
increased approximately $10.9 million and provision for bad debt increased
approximately $891,000.  These increases in physician affiliation expenses
resulted 

                                      -23-
<PAGE>
 
primarily from the same reasons stated above for the increase in net patient
service revenues and amounts retained by physician groups; namely that 1997
consisting of a full year of operations for MCP and Flagship I as compared with
a partial year operations in 1996 and the addition of Flagship II during 1997.

     General corporate expenses consist of all costs except depreciation and
amortization of the Company's corporate home office and regional operations.
The increase in general corporate expenses of approximately $2.7 million for the
year ended December 31, 1997 as compared to the year ended December 31, 1996 was
primarily due to the increase in home office and corporate regional operations
staff and related expenses to support the Company's growth.  However, corporate
expenses increased at a slower rate than overall revenue, declining from 77.4%
of net patient service revenue in 1996 to 15.9% in 1997.

     Depreciation and amortization expense consists primarily of amortization of
intangibles associated with affiliated practices.  The increases of
approximately $1.9 million from the year ended December 31, 1997 as compared to
the year ended December 31, 1996 was due to the increase in intangible assets
acquired as practice affiliations were completed, as well as 1997 consisting of
a full years depreciation and amortization for MCP and Flagship I as compared to
a partial year of depreciation and amortization during 1996.

     On October 24, 1997, the Company acquired a 50% interest in TLC and a 50%
interest in Total Quality.  The Company has accounted for the transaction using
the equity method of accounting for investments in common stock.  For the year
ended December 31, 1997, the net loss in investment was approximately $98,000.
The Company made no such investments in 1996.

     The increase in interest income of approximately $407,000 for the year
ended December 31, 1997 as compared to the year ended December 31, 1996 was
primarily due to a significant increase in the purchase of the Company's Class B
and Class C Common Stock by institutional investors during the year ended
December 31, 1997 as compared to the year ended December 31, 1996.  Proceeds
from the issuance of common stock to institutional investors, net of issuance
costs were approximately $25.8 million for the year ended December 31, 1997 as
compared to approximately $8.0 million for the year ended December 31, 1996.

Liquidity and Capital Resources
- -------------------------------

     The Company's principal requirements for capital are payments to physicians
in connection with affiliation transactions with the Company and its Affiliated
Groups, transaction costs associated with such affiliation transactions, working
capital requirements for its Affiliated Groups and the funding of operating
losses. The Company anticipates that its liquidity and capital resource
requirements will be similar on a long-term and short-term basis. Due to its
start-up status, the Company has incurred significant operating losses to date
and does not have operating cash flow to fund growth or further losses. The
Company's 

                                      -24-
<PAGE>
 
principal sources of capital to date have been the issuance of Class B and Class
C Common Stock to contain institutional investors, issuances of Class A Common
Stock to Physician Stockholders, other issuances of Class A Common Stock to
private investors, borrowing under a Credit Agreement with Bankers Trust Company
(which terminated on January 31, 1998) and cash generated by the operations of
the Affiliated Groups.

     During 1997 and 1996, the Company paid aggregate consideration of
approximately $23.6 and $29.5 million, respectively, in connection with
affiliation transactions. Of such amount, approximately $7.8 million in 1997 and
$5.9 in 1996 was paid in cash and approximately $15.8 million in 1997 and $23.6
in 1996 was paid in Class A Common Stock. The majority of such payments were
accounted for as an addition to intangible assets, which represented $26.1
million of the Company's total assets of $73.4 million at December 31, 1997. As
of December 31, 1997, intangible assets net of amortization costs, represent
approximately $57.3 million of the Company's total assets of approximately $73.4
million. The Company is amortizing the intangible assets over 25 years.

     Of the Company Common Stock outstanding at December 31, 1997, 18,157,982
shares of Class A Common Stock are subject to a put option which provides for
the put of the shares back to the Company at fair value upon the death or
disability of the holder. In addition, 1,029,749 of such shares are also subject
to a fair value put option back to the Company at the later of the shareholder's
retirement from the Company or June 1998. Consequently, these 18,157,982 shares
of Class A Common Stock have been recorded at fair value outside of permanent
equity in the accompanying balance sheet. Under the Company's stockholder
agreements, the holders of an aggregate of 15,471,063 shares of Class A Common
Stock, the Company may repurchase such shares for fair value if the
shareholder's termination of employment with the Company is without cause or is
by resignation, and for the lower of cost or fair value if termination is with
cause. The terms of such repurchase provision may not permit the Company to
fully recover its affiliation payments to the physician or reflect the cost of
affiliation transactions at the time of termination. To date, no Stockholder
Physician has terminated an employment agreement or repurchased any practice
assets. All of the above put and call provisions expire on the closing of a
public offering of the Company's common stock which results in net proceeds to
the Company of at least $50.0 million and which meets certain other criteria.
In addition to the previously discussed put options, the Flagship II physicians
have the right to require the Company to repurchase (in the form of a five year
non-interest bearing note) 4.8 million shares of Class A Common Stock issued in
the Flagship II affiliation at a purchase price of $3.00 per share if the
Company has not completed an underwritten initial public offering prior to
December 1, 2001.  Because the Company's shares are subject to a number of
restrictions in the stockholders' agreements and will not trade until the
occurrence of such an offering, the Company believes it is a nonpublic entity
for compensation accounting purposes and, accordingly, has not recorded any
compensation expense for these puts and calls.

     Working capital existing at the date of affiliation has generally been
retained in the practices. Therefore, additional working capital investment is
generally only required to the 

                                      -25-
<PAGE>
 
extent billing processing is slowed during payor administrative changes after an
affiliation and also to fund growth of revenues. The Company and its affiliated
entities had total net accounts receivable of $5.4 million and $11.9 million at
December 31, 1996 and 1997, respectively.

     The Company currently anticipates that its and the Affiliated Group's
capital expenditures during 1998 will be approximately $2.5 million.

     The Company has executed a contract with HMO and Company that obligates the
Company to purchase $1.1 million worth of equipment and licenses pertaining to
practice management systems. The term of the contract is five years.

Impact of Year 2000
- -------------------

     The Company is aware of issues associated with the programming code in
existing computer systems as the year 2000 approaches.  The "Year 2000" problem
is pervasive and complex, as virtually every computer operation will be affected
in the same way by the rollover of the two digit year value to 00.  The issue is
whether computer systems will properly recognize date sensitive information when
the year changes to 2000.  Systems that do not properly recognize such
information could generate enormous data or cause a system to fall.

     The Company is utilizing both internal and external resources to identify,
correct or reprogram, and test its systems for Year 2000 compliance.  It is
currently anticipated that all reprogramming efforts will be completed by July
31, 1999, allowing adequate time for testing.  A preliminary assessment has
indicted that some of the Company's older personal computers and ancillary
software programs may not be Year 2000 compatible.  The Company intends to
either replace or modify these computers and programs.  The cost of this
replacement is not expected to be material as the shelf life of the Company's
personal computers is three to five years.  The present financial systems are
all Year 2000 compliant. The practice management system is 80% compliant and the
Company plans to move to a newer version of the software which is 100% compliant
as part of it's reprogramming efforts which will be completed by July 31, 1999.
This upgrade is provided under the Company's current software maintenance
agreement with its software vendor.  All new software purchased will be 100%
compliant.

     The Company is also obtaining confirmations from the Company's primary
vendors that plans are already in place to address processing of transactions in
the Year 2000. However, there can be no assurance that the systems of other
companies on which the Company's systems rely also will be converted in a timely
fashion or that any such failure to convert by another company would not have an
adverse effect on the Company's systems. Management is in the process of
completing the assessment of the Year 2000 compliance costs.  However, based on
currently available information (excluding the possible impact of vendor systems
which management currently is not in a position to evaluate) as noted above,

                                      -26-
<PAGE>
 
management does not believe that these costs will have a material effect on the
Company's earnings.

Factors Affecting Future Operating Results
- ------------------------------------------

     Lack of Operating History; History of Operating Losses

     The Company's historical financial condition and results of operations may
not be indicative of the Company's results of operations and financial condition
for future periods. The Company has incurred losses of each of its fiscal years
through 1997. The Company expects to incur operating losses for at least the
immediate future and to fund such operating losses through the issuance of
additional equity and debt securities. See "-- Need for Substantial Additional
Capital." There can be no assurance that the Company will achieve or maintain
profitability.

     Need for Substantial Additional Capital

     The Company will require substantial capital resources to obtain the
necessary scale to become profitable and to fulfill its business plan.
Additional funds will be required to fund the acquisition, integration,
operation and expansion of affiliated practices, capital expenditures including
the development of the information systems to manage such practices, operating
losses and general corporate purposes.

     The Company has no committed external sources of capital. Without the
consent of the director elected by the stockholders of the Class B-1 Common
Stock (the "Class B-1 Director"), the director elected by the stockholders of
the Class B-2 Common Stock (the "Class B-2 Director," and together with the
Class B-1 Director the "Class B Directors") and the directors elected by the
holders of Class C Common Stock (the "Class C Directors"), the Company may not
obtain additional financing through external borrowings or the issuance of
additional securities. The issuance of additional capital stock could have an
adverse effect on the value of the shares of common stock held by the then
existing stockholders. There can be no assurance that the Class B Directors and
Class C Directors will approve such capital raising activities or that the
Company will be able to raise additional capital when needed on satisfactory
terms or at all. The failure to obtain additional financing when needed and on
appropriate terms could have a material adverse effect on the Company.
 
     Risk that Future Affiliation Transactions Will Not Be Consummated; Costs of
Affiliation Transactions

     There can be no assurance that any future affiliation transactions will be
consummated. In consummating future affiliation transactions, the Company will
rely upon certain representations, warranties and indemnities made by sellers
with respect to the affiliation transaction, as well as its own due diligence
investigation. There can be no assurance that such representations and
warranties will be true and correct, that the Company's due diligence 

                                      -27-
<PAGE>
 
will uncover all material adverse facts relating to the operations and financial
condition of the affiliated medical practices or that all of the conditions to
the Company's obligations to consummate these future affiliations will be
satisfied. Any material misrepresentations could have a material adverse effect
on the Company's financial condition and results of operations.

     The Company has incurred approximately $2.9 million and $567,000 during
1996 and 1997, respectively, in accounting, legal and other costs in developing
its affiliation structure and completing its initial affiliation transactions.
The Company's ability to enter into affiliation transactions with a significant
number of physicians and to achieve positive cash flow will be adversely
affected unless it is able to reduce the expenses associated with future
transactions. There can be no assurance that the Company will be able to reduce
transaction costs on a per affiliated physician basis in the future.

     Dependence upon Affiliated Medical Practices

     Although the Company does not and will not employ physicians or control the
medical aspects of the practices of the physicians employed by the Springfield
Affiliated Group, the Flagship Affiliated Group or similar Affiliated Groups,
the Company's revenue and profitability are directly dependent on the revenue
generated by the operation and performance of and referrals among the affiliated
medical practices. The compensation to the Company under its Services Agreements
with the Affiliated Groups is based upon a percentage of the profits or revenues
generated by the Affiliated Groups' practices with a substantial portion of the
profits or revenues being allocated to the physicians until threshold levels of
income or revenues, based upon the physicians' historical compensation or
billings, are achieved. Accordingly, the performance of affiliated physicians
affects the Company's profitability and the success of the Company depends, in
part, upon an increase in net revenues from the practice of affiliated
physicians compared to historical levels. The inability of the Company's
Affiliated Groups to attract and retain patients, to manage patient care
effectively and to generate sufficient revenue or a material decrease in the
revenues of the Affiliated Groups would have a material adverse effect on the
financial performance of the Company. To the extent that the physicians
affiliated with the Company are concentrated in a limited number of target
markets, as is currently the case in western Massachusetts and Maryland,
deterioration in the economies of such markets could have a material adverse
effect upon the Company.

     Risks Related to Expansion of Operations

     Integration Risks. The Company has completed affiliation transactions with
the Springfield Affiliated Group and the Flagship Affiliated Group, and is
seeking to enter into Affiliations with additional physicians. In the
Springfield and Greater Baltimore-Annapolis areas and in other potential
affiliation markets, the Company is integrating physician practice groups that
have previously operated independently. The Company is still in the process of
integrating its affiliated practices. The Company may encounter difficulties in
integrating the operations of such physician practice groups and the benefits
expected from such affiliations 

                                      -28-
<PAGE>
 
may not be realized. Any delays or unexpected costs incurred in connection with
integrating such operations could have an adverse effect on the Company's
business, operating results or financial condition.

         While each Affiliation conforms to PQC's overall business plan, the
profitability, location and culture of the physician practices that have been
combined into Affiliated Groups are different in some respects. PQC's management
faces a significant challenge in its efforts to integrate and expand the
business of the Affiliated Groups. The need for management to focus upon such
integration and future Affiliations may limit resources available for the day-
to-day management of the Company's business. While management of the Company
believes that the combination of these practices will serve to strengthen the
Company, there can be no assurance that management's efforts to integrate the
operations of the Company will be successful. The profitability of the Company
is largely dependent on its ability to develop and integrate networks of
physicians from the affiliated practices, to manage and control costs and to
realize economies of scale. There can be no assurances that there will not be
substantial costs associated with such activities or that there will not be
other material adverse effects on the financial results of the Company as a
result of these integration and affiliation activities.

         The Company intends to continue to pursue an aggressive growth strategy
through affiliations and internal development for the foreseeable future. The
Company's ability to pursue new growth opportunities successfully will depend on
many factors, including, among others, the Company's ability to identify
suitable growth opportunities and successfully integrate affiliated or acquired
businesses and practices. There can be no assurance that the Company will
anticipate all of the changing demands that expanding operations will impose on
its management, management information systems and physician network. Any
failure by the Company to adapt its systems and procedures to those changing
demands could have a material adverse effect on the operating results and
financial condition of the Company.

        Need to Hire and Retain Additional Physicians

         The success of the Company is dependent upon its ability to affiliate
with a significant number of qualified physicians and the willingness of such
affiliated physicians to maintain and enhance the productivity of their
practices following affiliation with PQC. The market for affiliation with
physicians is highly competitive, and the Company expects this competition to
increase. The Company competes for physician affiliations with many other
entities, some of which have substantially greater resources, greater name
recognition and a longer operating history than the Company and some of which
offer alternative affiliation strategies which the Company may not be able to
offer. In addition, under current law the Company has no or only limited ability
to enforce restrictive covenants in the employment agreements with the
physicians with whom the Company affiliates. The Company is subject to the risk
that physicians who receive affiliation payments may discontinue such
affiliation with the Company, resulting in a significant loss to the Company and
a decrease in the patient base associated with such affiliated physicians. There
can be no assurance that PQC will be able to

                                     -29-
<PAGE>
 
attract and retain a sufficient number of qualified physicians. If the Company
were unable to affiliate with and retain a sufficient number of physicians, the
Company's operating results and financial condition would be materially
adversely affected. A material increase in costs of affiliations could also
adversely affect PQC and its stockholders.

     Risk of Inability to Manage Expanding Operations

     The Company is seeking to expand its operations rapidly, which, if
successful, will create significant demands on the Company's administrative,
operational and financial personnel and systems. There can be no assurance that
the Company's systems, procedures, controls and staffing will be adequate to
support the proposed expansion of the Company's operations. The Company's future
operating results will substantially depend on the ability of its officers and
key employees to integrate the management of the Affiliated Groups, to implement
and improve operational, financial control and reporting systems and to manage
changing business conditions.

     Dependence Upon the Growth of Numbers of Covered Lives

     The Company is also largely dependent on the continued increase in the
number of covered lives under managed care and capitated contracts. This growth
may come from affiliation with additional physicians, increased enrollment with
managed care payors currently contracting with the Affiliated Groups and
additional agreements with managed care payors. A decline in covered lives or an
inability to increase the number of covered lives under contractual arrangement
with managed care or capitated payors could have a material adverse effect on
the operating results and financial condition of the Company.

     Potential Regulatory Restraints Upon the Company's Operations

     The healthcare industry is subject to extensive federal and state
regulation. Changes in the regulations or interpretations of existing
regulations could have a material adverse effect on the Company's business,
financial condition and results of operations.

     Risks of Capitated Contracts

     The physician groups with which the Company is affiliated and proposes to
affiliate are parties to certain capitated contracts with third party payors,
such as insurance companies. The Company intends to seek to expand the capitated
patient base of its Affiliated Groups, particularly for Medicare enrollees. In
general, risk contracts pay a flat dollar amount per enrollee in exchange for
the physician's obligation to provide or arrange for the provision of a broad
range of healthcare services (including in-patient care) to the enrollee. A
significant difference between a full risk capitated contract and traditional
managed care contracts is that the physician is sometimes responsible for both
professional physician services and many other healthcare services, e.g.,
hospital, laboratory, nursing home and home health. The physician is not only
the "gatekeeper" for enrollees, but is also financially at risk for 

                                      -30-
<PAGE>
 
over-utilization and for the actuarial risk that certain patients may consume
significantly more healthcare resources than average for patients of similar age
and sex (such patients are referred to herein as "high risk patients").

     While physicians often purchase reinsurance to cover some of the actuarial
risk associated with high risk patients, such insurance typically does not apply
with respect to the risk of over-utilization until a relatively high level of
aggregate claims has been experienced and therefore does not completely protect
against any capitation risk assumed. If over-utilization occurs with respect to
a given physician's enrollees (or the physician's panel of enrollees includes a
disproportionate share of high risk patients not covered by reinsurance), the
physician is typically penalized by failing to receive some or all of the
physician's compensation under the contract that is contingent upon the
attainment of negotiated financial targets, or the physician may be required to
reimburse the payor for excess costs. In addition, a physician may be liable for
over-utilization by other physicians in the same "risk pool" and for utilization
of ancillary, in-patient hospital and other services when the physician has
agreed contractually to manage the use of those services. Neither the Company
nor the Affiliated Groups currently maintain any reinsurance arrangement and, to
date, the Affiliated Groups have not experienced losses from participation in
risk pools or incurred any material penalties or obligations with respect to
excess costs under capitated contracts. The Company is pursuing a strategy of
seeking increased participation in capitated contracts for all of its affiliated
physicians. As the percentage of the Company's revenues derived from capitated
contracts increases, the risk of the Company experiencing losses under capitated
contracts increases. As the revenues from capitated contracts became of
increasing importance to PQC and its Affiliated Groups, the Company will review
the financial attractiveness of reinsurance arrangements.

     Medical providers, such as the Affiliated Groups, are experiencing
increasing pricing pressure in negotiating capitated contracts while facing
increased demands on the quality of their services. If these trends continue,
the costs of providing physician services could increase while the level of
reimbursement could grow at a lower rate or decrease. Because the Company's
financial results are dependent upon the profitability of such capitated
contracts, the Company's results will reflect the financial risk associated with
such capitated contracts. Liabilities or insufficient revenues under capitated
and other risk-sharing arrangements could have a material adverse effect on the
Company.

     Risks of Changes in Payment for Medical Services

     The profitability of the Company may be adversely affected by Medicare and
Medicaid regulations, cost containment decisions of third party payors and other
payment factors over which PQC and its Affiliated Groups have no control.  The
federal Medicare program has undergone significant legislative and regulatory
changes in the reimbursement and fraud and abuse areas, including the adoption
of RBRVS schedule for physician compensation under Medicare, which may have a
negative impact on PQC's revenue. Efforts to control the cost of healthcare
services are increasing.  PQC's Affiliated Groups contract 

                                      -31-
<PAGE>
 
with provider networks, managed care organization and other organized healthcare
systems, which often provided fixed fee schedules or capitation payment
arrangements which are lower than standard charges. Future profitability in the
changing healthcare environment, with differing methods of payment for medical
services, is likely to be affected significantly by management of healthcare
costs, pricing of services and agreements with payors. Because PQC derives its
revenues from the revenues generated by its affiliated physician groups, further
reductions in payment to physicians generally or other changes in payment for
healthcare services could have an adverse effect on the Company.

     Exposure to Professional Liability; Liability Insurance

     In recent years, physicians, hospitals and other participants in the
healthcare industry have become subject to an increasing number of lawsuits
alleging medical malpractice, negligent credentialing of physicians, and related
legal theories. Many of these lawsuits involve large claims and substantial
defense costs. There can be no assurance that the Company will not become
involved in such litigation in the future. Through its management of practice
locations and provision of non-physician healthcare personnel, the Company could
be named in actions involving care rendered to patients by physicians or other
practitioners employed by Affiliated Groups. In addition, to the extent that
affiliated physicians are subject to such claims, the physicians may need to
devote time to defending such claims, adversely affecting their financial
performance for the Company, and potentially having an adverse effect upon their
reputations and client base. The Company and the Affiliated Groups maintain
professional and general liability insurance, which is currently maintained at
$1 million per occurrence and $3 million annually for each affiliated physician.
Nevertheless, certain types of risks and liabilities are not covered by
insurance, and there can be no assurance that the limits of coverage will be
adequate to cover losses in all instances.

     Certain Federal Income Tax Considerations

     Physician groups which operated as PCs in Springfield prior to affiliating
with the Company were merged into the Springfield Affiliated Group, with
stockholders of each PC receiving shares of Class A Common Stock of the Company
and cash in exchange for their capital stock in the PC. Physician groups which
operated as PAs in the greater Baltimore-Annapolis area prior to affiliating
with the Company were similarly merged into the Flagship Affiliated Group, with
stockholders of each PA receiving shares of Class A Common Stock of the Company
and cash in exchange for their capital stock in the PA. Each such merger is
intended to qualify as a "reorganization" under Section 368(a) of the Internal
Revenue Code of 1986, as amended (the "Code"), in which case no gain or loss
would generally be recognized by the PC or PA or the stockholders (other than as
cash received) of the PC or PA. The Company has not sought or obtained a ruling
from the Internal Revenue Service or an opinion of counsel with respect to the
tax treatment of the mergers of PCs or PAs into the Springfield or Flagship
Affiliated Groups. The Company does not believe that the Internal Revenue
Service is issuing rulings at this time on transactions using the Company's
affiliation structure. If a merger were not to so qualify, the exchange of
shares 

                                      -32-
<PAGE>
 
would be taxable to the stockholders of the PC or PA, and the consideration (net
of asset basis) issued in connection with the merger would be taxable to the
Affiliated Group into which such PC or PA was merged. Because of such tax
liability, failure of a merger or mergers to qualify as tax-free reorganizations
could have a material adverse effect on the applicable Affiliated Group and the
Company. Also, the inability to structure future Affiliations on a tax deferred
basis may adversely affect the Company's ability to attract additional
physicians.

     New Management; Dependence on Key Personnel

     The current management structure and the senior management team of the
Company have been in place for a relatively short time. The Company's future
success depends, in large part, on the continued service of Jerilyn P. Asher,
the Chief Executive Officer, and on PQC's ability to continue to attract,
motivate and retain highly qualified senior management and employees. The
Company has an employment agreement with Ms. Asher. The Company does not
maintain key person life insurance with respect to Ms. Asher. As a development
stage company, PQC has experienced some turnover in staff, including two of the
founding officers. The Company and one of the departed founders are currently in
a dispute concerning the vesting of approximately 400,000 shares of Class A
Common Stock granted to the founder and the founder's right to severance
payments of approximately $440,000. Although the Company has entered into
employment agreements with certain of its other executives that contain
covenants not to compete with the Company, there can be no assurance that the
Company will be able to retain such key executives or its senior managers and
employees. The inability to hire and retain qualified personnel or the loss of
the services of personnel could have a material adverse effect upon the
Company's business and future business prospects.

     Risk of the Unavailability of the Equity Facility

     The remaining amount under the Class B and Class C Stock Purchase Agreement
(the "Equity Facility') with certain institutional inventors ("Institutional
Investors") is only available with the consent of the Institutional Investors
and there can be no assurance that the Institutional Investors will be willing
to provide additional capital when needed by the Company. The Equity Facility
also restricts the sources of capital available to the Company without the
consent of the Institutional Investors. Except for the Equity Facility, the
Company has no committed external sources of capital.  Except with the consent
of the director elected by the Institutional Investors, the Company may not
obtain additional financing through external borrowings or the issuance of
additional securities. The Institutional Investors also have received warrants
to purchase a substantial number of shares of Class A Common Stock. These
warrants are exercisable at $2.50 or $3.25 per share, which exercise price may
be substantially below the fair market value of the Class A Common Stock at the
time of exercise. Any additional equity issuance could have an adverse effect on
the value of the shares of Class A Common Stock held by the then existing
stockholders.

                                      -33-
<PAGE>
 
     Risks from Put and Other Rights Held by Certain Stockholders

     Each physician and management stockholder who is a party to the
Stockholders Agreement, dated as of August 30, 1996 (the "Stockholder's
Agreement"), has the right to require PQC to purchase the Common Stock owned by
such stockholder at fair market value upon their death or disability.  Pursuant
to the Stockholders Agreement, fair market value, as determined by the Board of
Directors, reflects an arms-length private sale. In determining the fair market
value, the Board is to consider recent arms-length sales by the Company and the
stockholders, as well as other factors considered relevant. While the
Stockholders Agreement does not limit the Board's discretion, such other factors
may include changes, since the last arms-length sale, in the Company's financial
conditions or prospects and any valuation studies conducted by management of the
Company or independent valuation experts. Under the Stockholder Agreement, the
Board is not permitted to discount the fair market value of the Common Stock to
reflect the fact that the Common Stock being sold constitutes less than a
majority of the outstanding shares. The put option is only triggered by death or
disability (and in a few instances retirement) and will terminate upon the
completion of a public offering which results in at least $50.0 million in gross
revenues to the Company and which meets certain other criteria. The physician
affiliated with Clinical Associates have the right to require the Company to
repurchase their Common Stock at $3.00 per share (in the form of a five year,
non-interest bearing note) in the event that the Company has not completed an
underwritten initial public offering within four years. The exercise of such
right could have a material adverse effect upon the Company. To the extent that
the "put options" are likely to be exercised, the Company expects to fund such
repurchases from working capital, the Equity Facility or other sources.

     Amortization of Intangible Assets

     In connection with its Affiliations, the Company has recorded, and is
expected to continue to record, a significant amount of intangible assets as the
consideration paid to physicians exceeds the value of the practice assets. At
December 31, 1997, the Company had intangible assets of approximately $57.3
million reflected on its balance sheet as long-term affiliation agreements. The
Company amortizes such intangible assets over a 25 year period. See the Notes to
the Company's Financial Statements. The amortization of these intangible assets,
while not affecting the Company's cash flow, has an ongoing negative impact upon
the Company's earnings. During the year ended December 31, 1997, amortization of
intangible assets contributed approximately $1,292,000 to the Company's net loss
of $5.7 million.

                             Employment Agreements
                             ---------------------

     The Company is a party to an employment agreement with Jerilyn P. Asher
pursuant to which Ms. Asher serves as Chief Executive Officer of the Company for
the three-year period ending June 21, 1998. The term of the agreement will be
automatically extended for successive one-year terms, unless the Company
notifies Ms. Asher to the contrary at least 90 days prior to the expiration of
the then current term. For her services, Ms. Asher is entitled to an initial
base salary of $250,000 per year (subject to periodic increases as determined by
the Board) and is eligible to receive bonuses under the Company's management
incentive program, if such a program is adopted, in an amount up to 100% of her
base pay based upon individual and Company performance. Pursuant to an amendment
to the employment agreement dated August 30, 1996, Ms. Asher waived the right to
receive any unpaid amounts of base salary and bonus to which she was entitled
and had not received as of August 1, 1996. Ms. Asher is also entitled to receive
other benefits available to the Company's senior management generally. Pursuant
to a stock restriction agreement executed as of the date of 

                                      -39-
<PAGE>
 
the employment agreement, the Company issued 4,162,500 shares of Series A Common
Stock to Ms. Asher at a purchase price of $.01 per share, 346,875 of which
remain subject to vesting if Ms. Asher maintains her employment with the Company
until June 1998, which vesting will be accelerated in the event of a Change in
Control. A Change in Control is defined to include a person or group becoming
the beneficial owner of 50% or more of the outstanding voting securities of the
Company, certain changes to the composition of the Board of Directors, certain
mergers and a liquidation of the Company. A percentage of the vested shares (50%
in the case of termination for cause and 35% in the case of voluntary
termination) are subject to the Company's repurchase rights in certain
circumstances, including termination of Ms. Asher for "cause" or Ms. Asher's
voluntary resignation, at the fair market value at the time of repurchase.

     The Company may terminate Ms. Asher's employment at any time without cause
and upon 10 days' written notice with cause. Ms. Asher may terminate her
employment for any reason upon 90 days' written notice. If Ms. Asher's
employment is terminated by the Company without cause, or if Ms. Asher
terminates her employment for good reason, the Company must pay Ms. Asher an
amount equal to two times her annual salary. Cause, for purposes of the
termination provisions, means willful and continued failure to perform her
duties, willful engagement in misconduct materially injurious to the Company or
her conviction for a felony, fraud or embezzlement of the Company's property. In
addition, the Company must also make such payment if Ms. Asher's employment is
terminated at any time within 24 months after a "Change in Control" for any
reason other than (i) death or disability, (ii) by the Company for Cause or
(iii) by Ms. Asher other than for Good Reason.

     During the term of the agreement, the Company must nominate Ms. Asher to
and Ms. Asher will be eligible to serve on the Board of Directors. Ms. Asher
also agreed to standard non-competition and non-disclosure terms with the
Company.

     The Company is also party to an employment agreement with Arlan F. Fuller,
pursuant to which Dr. Fuller serves as Executive Vice President, Medical
Information Systems and Academic Development of the Company for the three-year
period ending June 20, 1998. The term of the agreement will be automatically
extended for successive one-year terms, unless the Company notifies Dr. Fuller
to the contrary at least 90 days prior to the expiration of the then current
term. Dr. Fuller was required to devote 40% of his time to the Company and, for
such services, was entitled to an initial base salary of $175,000 per year
(subject to periodic increases as determined by the Board). Dr. Fuller reduced
his base annual salary to $50,000 beginning in December 1996. Pursuant to a
stock restriction agreement executed as of the date of the employment agreement,
the Company issued 618,750 shares of Common Stock to Dr. Fuller at a purchase
price of $.01 per share. These shares are subject to vesting based on individual
performance and duration of employment, which vesting will be accelerated in the
event of a "Change in Control." The Company may terminate Dr. Fuller's
employment at any time with cause and upon 60 days' notice without cause. Dr.
Fuller may terminate his employment for any reason upon 60 days' written notice.

(1)  Amounts represent hypothetical gains that could be achieved for respective
     options if exercised at the end of the option term.  These gains are based
     on assumed rates of stock price appreciation of 5% and 10%, compounded
     annually from the date the respective options were granted to their
     expiration date.  The gains shown are net of the option exercise price, but
     do not include deductions for taxes or other expenses associated with the
     exercise. Actual gains, if any, on stock option exercises will depend on
     the future performance of the Common Stock, the option holder's continued
     employment through the option period and the date on which the options are
     exercised.

(2)  The exercise price is equal to the fair market value of the Company's
     Common Stock on the date of grant.

(3)  The expiration date of an option is the tenth anniversary of the date on
     which the option was originally granted.

(4)  Of these stock options, 100,000 stock options vest immediately and the
     remaining stock options vest in two equal annual installments commencing on
     the first anniversary of the date on which the option was originally
     granted. Of these options 120,000 are intended to qualify as incentive
     stock options and the remainder are non-statutory stock options. The
     vesting of these stock options is accelerated in the event of a change in
     control of the Company.

(5)  These stock options vest in three annual installments of 150,000, 125,000
     and 125,000 shares commencing on the first anniversary of the date on which
     the option was originally granted. Of these options 120,000 are intended to
     qualify as incentive stock options and the remainder are non-statutory
     stock options. The vesting of these stock options is accelerated in the
     event of a change in control of the Company.

The Board of Directors
Physicians Quality Care, Inc.

We have audited the accompanying balance sheets of Physicians Quality Care, Inc.
(the Company) as of December 31, 1997 and 1996, and the related statements of
operations, stockholders' equity and common stock subject to put, and cash flows
for the period from March 20, 1995 (inception) to December 31, 1995 and the
years ended December 31, 1996 and 1997.  These financial statements are the
responsibility of the Company's management.  Our responsibility is to express an
opinion on these 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 financial statements referred to above present fairly, in
all material respects, the financial position of Physicians Quality Care, Inc.
as of December 31, 1997 and 1996 and the results of its operations and its cash
flows for the period from March 20, 1995 (inception) to December 31, 1995, and
the years ended December 31, 1996 and 1997, in conformity with generally
accepted accounting principles.

1.  BUSINESS AND ORGANIZATION

Formed in March 1995, Physicians Quality Care, Inc. (PQC or the Company)
provides complete practice management for multi-specialty medical practice
groups.  The Company's objective is to establish and manage networks of
specialty and primary care physicians and related diagnostic and therapeutic
support services which can provide comprehensive health care services in
targeted geographic areas.

During 1996 and 1997, the Company completed affiliations with physician
practices in Springfield, Massachusetts, and in the Baltimore/Annapolis,
Maryland area.  Prior to August 30, 1996, the Company's operations consisted
primarily of seeking affiliations with physician practices and negotiating the
terms of the affiliations and management agreements with such physician
practices.


2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES

BASIS OF PRESENTATION

The Company enters into long-term affiliation arrangements with physician 
practices, and through mergers and asset purchases, the assets and liabilities 
of the physician practices are transferred to a professional corporation 
affiliated with the Company. Each affiliated group has a nine member joint 
Policy Board that is responsible for final decisions related to management and 
administrative policies for the overall operations of the affiliated group 
including decisions regarding; scope of services, patient acceptance policies 
and procedures, pricing of services, negotiation and execution of contracts and 
approval of operating and capital budgets. Four members of the Joint Policy 
Board are appointed by the Company and four members are appointed by the 
affiliated group. The President, who is the ninth member of the Joint Policy 
Board, is appointed by the Company; however, the Company may only select the 
President from three physicians nominated by physicians employed by the 
affiliated group. Therefore, the Company cannot exercise exclusive authority 
over the decision making process of the Joint Policy Board. Accordingly, for 
financial reporting purposes, the Company does not consolidate the operating 
results and accounts of the physician practices. For display purposes, the 
Company has presented the physician practice revenues and amounts retained by 
the physician practices in the accompanying statements of operations to arrive 
at the Company's management fee revenue. See further discussion below.

NET PATIENT SERVICE REVENUE

Net patient service revenue represents the revenue of the physician practices
reported at the estimated realizable amounts from patients, third-party payors
and others for services rendered, net of contractual and other adjustments.

During 1996 and 1997, respectively, the Company estimates that approximately 40%
and 35% of net patient service revenue was received under government-sponsored
healthcare programs (principally, the Medicare and Medicaid programs).

The Company has agreements with various Health Maintenance Organizations (HMOs)
to provide medical services to subscribing participants.  Under these
agreements, the Company receives monthly capitation payments based on the number
of each HMO's participants.

MANAGEMENT FEE REVENUE

Management fee revenue represents net patient service revenue less amounts
retained by physician practices.  The amounts retained by physician practices
represents amounts paid to the physicians pursuant to the service agreements
between the Company and the physician practices.  Physician baseline
compensation is determined based on an agreed-upon percentage (80% to 95%) of
the physicians' historic compensation levels, but is subject to reduction if
physician practice net revenues are insufficient to cover the baseline
compensation for two of the physician groups.  The amounts allocated to the
Company and to the physician groups are determined based on a percentage of
physician group revenue in excess of physician baseline compensation and
reimbursement of practice expenses (hereafter referred to as net profits).  The
net profits for one of the Company's Affiliated Groups are first allocated to
the Company up to 5% of the net profits.  Net profits remaining after the first
allocation are then allocated 80% to the Company and 20% to the physician groups
up to $1.5 million.  Net profits remaining after the second allocation are then
allocated equally between the Company and the physician groups.  The net profits
for the Other Affiliated Group are allocated equally between the Company and the
physician groups.

The following details the amounts retained by physician groups and the
management fee revenue for the year ended December 31, 1997 and 1996:

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

Under the service agreements, the Company provides each physician practice with
a comprehensive package of services, including office and facilities, equipment,
nursing and other non-physician professional support, administrative support,
information systems, comprehensive professional liability insurance, and general
management and financial advisory services.  The Company also bills all
patients, insurance companies and third-party payors and negotiates all
contracts and relationships with payors.

CASH AND CASH EQUIVALENTS

The Company considers all highly liquid investments with a maturity of three
months or less at the time of purchase to be cash equivalents.  The carrying
amount reported in the balance sheet for cash and cash equivalents approximates
its fair value.

PROPERTY AND EQUIPMENT

Property and equipment is carried at cost.  Depreciation is calculated using the
straight-line method over the useful lives of the assets.

PROFESSIONAL LIABILITY INSURANCE

The Company has obtained professional liability coverage for the Physician
Practices through commercial insurance carriers on either a claims-made or
occurrence basis.  The Company has purchased additional insurance to cover the
tail portion of the claims made policies.  Management believes that there are no
claims that may result in a loss in excess of amounts covered by its existing
insurance.

INVESTMENT IN LONG TERM AFFILIATION AGREEMENTS

The cost of the long-term affiliation agreements in excess of the underlying
equity of the affiliated groups is being amortized on a straight-line basis over
25 years.

STOCK COMPENSATION ARRANGEMENTS

As permitted under SFAS 123 the Company accounts for its stock compensation
arrangements under the provisions of APB Opinion No. 25, "Accounting for Stock
Issued to Employees" (APB 25).  Because the exercise price of options granted
during 1997, 1996 and 1995 equals the fair value of the underlying stock at date
of grant, no compensation expense is required under APB 25.

                                                                               8

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

The Company has adopted disclosure-only provisions of Statement of Financial
Accounting Standards No. 123, "Accounting for Stock-Based Compensation" (SFAS
123).  These provisions require the Company to disclose pro forma net income and
earnings per share amounts as if compensation expense related to grants of stock
options were recognized based on new fair value accounting rules.

NET LOSS PER COMMON SHARE

In February 1997, the Financial Accounting Standards Board issued Statement of
Financial Accounting Standards No. 128 "Earnings per Share" (SFAS 128), which
establishes standards for computing and presenting earnings per share (EPS) and
applies to entities with publicly held common stock or potential common stock.
This Statement is effective for financial statements issued for both interim and
annual periods ending after December 15, 1997 and requires restatement of all
prior period EPS data.  The Company has applied this standard in 1997 and has
restated EPS for 1995 and 1996.

Basic net loss per share of common stock is computed by dividing the net loss
available to common stock by the weighted-average number of common shares
outstanding during each period presented.  Diluted loss per share is not
presented because the effect would be antidilutive.

RISKS AND UNCERTAINTIES

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 at the date of the
financial statements and the reported amounts of revenues and expenses during
the reporting period.  Actual results could differ from those estimates.

                                                                               9

2.  SUMMARY OF SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

PENDING ACCOUNTING STANDARDS

In June 1997, the Financial Accounting Standards Board issued SFAS No. 130,
Reporting Comprehensive Income and SFAS No. 131, Disclosures About Segments of
an Enterprise and Related Information.  SFAS No. 130 establishes standards for
reporting and displaying comprehensive income and its components.  SFAS No. 131
establishes standards for public companies to report information about operating
segments in financial statements, and supersedes SFAS No. 14, Financial
Reporting for Segments of an Business Enterprise, but retains the requirements
to report information about major customers.  SFAS No. 130 and SFAS No. 131 are
effective for the Company in 1998.  The Company does not believe the adoption of
these Statements will have a significant effect on its financial statements.

In November 1997, the Financial Accounting Standards Board's Emerging Issues
Task Force reached a consensus on its Issue 97-2, Consolidation of Physician
Practice Entities which is effective for the Company for its 1998 annual
financial statements.  The Company is currently evaluating the guidance
contained in the consensus as it affects its current model for its affiliation
structures.  However, management does not believe implementation of the
consensus guidance will materially affect the financial position or its net
results of operations.

RECLASSIFICATION

Certain amounts in the financial statements have been reclassed for the basis of
presenting corresponding items in the comparative financial statements.

3.  AFFILIATIONS

Springfield

On January 1, 1997, the Company entered into long-term affiliation arrangements
with 2 physician practices (5 physicians) located in Western Massachusetts (the
Springfield Affiliation).  On August 30, 1996, the Company entered into long-
term affiliation arrangements with 7 physician practices (32 physicians) located
in Western Massachusetts (the Springfield Affiliation).  In connection with
these transactions, the assets and liabilities of the physician practices were
transferred to a professional corporation affiliated with the Company, Medical
Care Partners, P.C. (MCP) and the physicians became employees of MCP.  The
aggregate consideration paid to the physicians for the 1997 affiliation was
approximately $2.5 million, of which  $831,000

                                                                              10

was paid in cash, $1.4 million was paid by the issuance of 572,493 shares of
Class A common stock, and $225,000 was paid by the issuance of options to
purchase shares of common stock at below fair value. The aggregate consideration
paid to the physicians for the 1996 affiliation was approximately $9.7 million,
of which $3.2 million was paid in cash and $6.5 million was paid by the issuance
of 2,592,245 shares of Class A common stock. Up to an additional $2.15 million,
payable in Class A common stock, was available to be paid to certain physicians
if revenue goals were met. During 1997, $2.1 million of additional consideration
was accrued based on the achievement of these goals and will be paid during
1998. In addition, 29 physicians each received 2,500 options to purchase common
stock at an exercise price equal to fair value.

Baltimore

On December 1, 1997, the Company entered into a long-term affiliation
arrangement with a physician practice (58 physicians) located in the
Baltimore/Annapolis, Maryland area (the Flagship II Affiliation).  In connection
with this transaction, the assets and liabilities of the physician practices
were transferred to a newly formed professional corporation affiliated with the
Company, Flagship Health II, P.A. (Flagship II) and the physicians became
employees of Flagship II.  The aggregate consideration paid to the physicians
for the affiliation was approximately $17.4 million, of which $3 million was
paid in cash and $14.4 million was paid by the issuance of 4,800,000 shares of
Class A common stock.

On December 11, 1996, the Company entered into long-term affiliation
arrangements with 15 physician practices (59 physicians) located in the
Baltimore/Annapolis, Maryland area. In connection with this transaction, the
assets and liabilities of the physician practices were transferred to a newly
formed professional corporation affiliated with the Company, Flagship Health I,
P.A. (Flagship I) and the physicians became employees of Flagship I. The
aggregate consideration paid to the physicians for the affiliation was
approximately $19.8 million, of which $2.7 million was paid in cash and $17.1
million was paid by the issuance of 6,842,675 shares of Class A common stock.
During 1997, the Company issued 44,900 shares of Class A common stock to the
Flagship I physicians totalling $112,000 for the settlement of working capital
adjustments.

As described in Note 2, the Company does not consolidate the operating results
or accounts of the affiliated physician practices for financial reporting
purposes.  Accordingly, its investments in these long-term affiliation
agreements are accounted for in a manner similar to that used in the application
of the equity method of accounting.  Therefore, the costs of the long-term
affiliation agreements in excess of the underlying equity of affiliated groups
is accounted for as an intangible asset and amortized on a straight-line basis
over 25 years.

4.  ACQUISITIONS

On October 24, 1997, the Company acquired a 50% interest in TLC Management
Company, a medical management company and a 50 % interest in Total Quality
Practice Management, Inc., a practice management company providing Medicare risk
management services.  Both companies are based in Atlanta, GA.  Total aggregate
consideration was $4 million paid in cash and an obligation to issue a $1
million letter of credit.  As of December 31, 1997, the letter of credit has not
been issued.  The Company has accounted for the transaction using the equity
method of accounting for investments in common stock.  For the year ended
December 31, 1997, the net loss in investment was $98,269.

6.  TRANSACTIONS WITH RELATED PARTIES

The amounts due under the service agreements with the affiliated practices
represent management fee revenue due the Company net of nonphysician salaries
and benefits and other practice related expenses paid by the Company on behalf
of the affiliated practices.



The amounts due as a result of working capital and other adjustments at date of
affiliation, represent post closing adjustments provided for as part of the
affiliation agreements.  The corresponding credits were reflected as a reduction
in the cost of the long-term affiliation agreements.

Because of the nature of the Company's arrangements with the affiliated
physician groups, substantially all transactions included in net patient service
revenues and amounts retained by physician groups in the accompanying financial
statements are viewed as related-party transactions.

                                                                              13

transactions with three of its directors who are physicians.  The physicians
received 498,602 shares of Class A common stock, 2,500 options to acquire Class
A common stock, with an exercise price of $2.50 per share and cash in the amount
of $315,000 as consideration for the affiliations.

On August 30, 1996, the Company entered into a Management Agreement with Bain
Capital Partners V, L.P. (Bain), an affiliate of the Company's Institutional
Investors (see Note 6).  Pursuant to the Management Agreement, the Company has
agreed to pay Bain a management fee of $750,000, plus 1% of any financings from
parties other than affiliates of Bain, for services including advice in
connection with financings and financial, managerial and operational advice in
connection with day-to-day operations.  The Company is also obligated to pay
certain expenses, not to exceed $100,000 per year without the Company's consent,
of Bain and its affiliates in connection with the Management Agreement.

7.  LEASES

The Company and its affiliates maintain operating leases for property and 
certain office equipment. The property leases contain renewal options and 
escalation clauses and require payments of certain utilities and taxes over 
established base amounts.

Operating lease expense amounted to $3,136,822, $535,479 and $14,679 for the
years ended December 31, 1997 and 1996 and the period from inception to December
31, 1995, respectively.

Future minimum lease payments under noncancelable capital and operating leases 
follow. All amounts, excluding approximately $162,000 in 1998, are the 
obligations of the Company's affiliated groups.

8.  STOCKHOLDERS' EQUITY

Preferred Stock
- ---------------

During June 1995, the Company issued 1,666,151 shares of Series A Convertible
Preferred Stock (Preferred Stock), par value $.01, that was converted to Class A
common stock on a one-for-one basis in connection with the recapitalization
discussed below. Warrants to purchase 416,538 shares of Common Stock at $2.40
per share were issued upon the closing of the sale of the Preferred Stock.
Warrants to purchase an additional 416,538 shares of common stock were required
to be issued to the holders of the Preferred Stock in the event that the Company
did not complete an initial public offering on or before June 30, 1996.
Accordingly, on August 30, 1996, the Company issued an additional 416,538
warrants at $2.40 per share. A total value of $300,000 were assigned to these
warrants.

In connection with the recapitalization, the Company authorized 10 million 
shares of $.01 par value preferred stock.

Common Stock
- ------------

The Company has four classes of common stock; Class A, Class B-1, Class B-2 and
Class C. The primary difference between these four classes is voting rights.
Holders of Class A, Class B-1, Class B-2 and Class C common shares are entitled
to elect two, one, two and one members of the Company's Board of Directors,
respectively. The remaining seven directors are elected collectively by the
holders of Class A, Class B-1, Class B-2 and Class C common shares, with each
share having a single vote.


During the period from March 20, 1995 (inception) to December 31, 1995, the
Company issued 7,706,250 shares of $.01 par value common stock to its founders
in exchange for cash of $15,188 and notes of $61,875.  During the year ended
December 31, 1996, 1,012,500 shares of common stock were reacquired by the
Company at a cost of $10,125 in the form of cancellation of a like amount of a
note due from the shareholder.  These shares are subject to certain restrictions
which lapse in August 1998. Effective August 30, 1996, the Company
recapitalized. All shares of then-existing common stock were canceled and
replaced with Class A common shares.

On August 30, 1996, 402,301 of Class A common shares were issued in connection
with the conversion of a bridge loan.  The bridge loan, in the amount of $1.0
million, (1) was outstanding during July and August 1996;  (2) bore interest at
10.25% and (3) was convertible into Class A common shares at a conversion rate
of $2.50 per share.  Warrants to purchase 201,150 shares of common stock at
$5.00 per share were issued in connection with the bridge loan.


                                                                             15

8.  STOCKHOLDERS' EQUITY (CONTINUED)

During August 1996, 625,000 shares of Class A common stock were issued in
connection with the conversion of a promissory note.

In connection with the Springfield Affiliation described in Note 3, on August
30, 1996, the Company issued 1,587,863 Class B-1 common shares, 1,012,137 Class
B-2 common shares and warrants to purchase 3,750,500 shares of Class B common
stock at $2.50 per share to the Institutional Investors in exchange for cash
proceeds of $6.5 million, which after issuance costs of approximately $1.4
million, netted to approximately $5.1 million.  In connection with the Baltimore
Affiliation described in Note 3, on December 11, 1996, the Company issued
855,003 Class B-1 common shares, 544,997 Class B-2 common shares and warrants to
purchase 1,799,000 shares of Class B common stock at $2.50 per share to the
Institutional Investors in exchange for cash proceeds of $3.5 million, which
after issuance costs of approximately $640,000, netted to approximately $2.9
million.

In April 1997, the Company issued 366,430 Class B-1 common shares, 233,570 Class
B-2 common shares and warrants to purchase 865,500 shares of Class B common
stock at $2.50 per share to the Institutional Investors in exchange for cash
proceeds of $1.5 million.

Subject to certain conditions, the Institutional Investors are required to
purchase up to 8,000,000 additional shares of Class B common stock, together
with warrants to purchase up to 7,450,500 shares of Class B common stock, for
aggregate consideration of $20,000,000.  These shares may be sold no later than
December 31, 1999.

In connection with the Flagship II Affiliation described in Note 3, on June 30,
1997, the Company issued 7,692,309 Class C common shares, at $3.25 per share to
the Institutional Investors in exchange for cash proceeds of $25 million, which

million.

Puts and Calls
- --------------

Of the Company's outstanding common stock, 18,157,982 shares as of December 31,
1997 are subject to a put option which provides for the put of the shares back
to the Company at fair value upon the death of the holder. In addition,
1,029,749 of such shares are also subject to a fair value put option back to the
Company at the later of the shareholder's retirement from the Company or June,
1998. Consequently, common shares have been recorded at fair value outside of
permanent equity in the accompanying balance sheet.

Under shareholder agreements as of December 31, 1997, the Company has the right
to purchase 15,471,063 shares of common stock for fair value if the
shareholder's termination from the Company is without cause or is by
resignation, and for the lower of cost or fair value if termination is with
cause.

All of the above put and call provisions expire on the date of a Qualified
Public Offering (QPO), defined as a public offering of the Company's common
stock with proceeds to the Company of at least $50 million.

In addition to the previously discussed put options, the Flagship II physicians 
have the right to require the Company to repurchase (in the form of a five year 
non-interest bearing note) 4.8 million shares of Class A common stock issued in 
the Flagship II affiliation (note 3) at a purchase price of $3.00 per share if 
the Company has not completed an underwritten initial public offering prior to 
December 1, 2001.

Because the Company's shares are subject to a number of restrictions in the
shareholders' agreements and will not trade until the occurrence of a QPO, the
Company believes it is a nonpublic entity for compensation accounting purposes
and, accordingly, has not recorded any compensation expense for these puts and
calls.  As noted above, at the date of the QPO, the put and call provisions of
the shareholder agreements will expire.

                                                                              17

</TABLE>

The effect of options (Note 9) and warrants (Note 7) are not considered, as it
would be anti-dilutive for the years presented.  At December 31, 1997, these
securities, if converted, could potentially dilute basic earnings per common
share in the future.

10.  Employee Compensation Plans

Equity Incentive Plan
- ---------------------

The Company's 1995 Equity Incentive Plan provides the opportunity for employees,
consultants, officers and directors to be granted options to purchase, receive
awards or make direct purchases of up to 3.5 million shares of the Company's
common stock.  Options granted under the Plan may be "Incentive Stock Options"
or "Nonqualified Options" under the applicable provisions of the Internal
Revenue Code.

Incentive Stock Options are granted at the fair market value of the Company's
common stock at the date of the grant as determined by the Board of Directors.
Incentive Stock Options granted to employees who own more than 10% of the voting
power of all classes of stock will be granted at 110% of the fair market value
of the Company's common stock at the date of the grant.  Nonqualified options
may be granted at amounts up to the fair market value of the Company's common
stock on the date of the grant, as determined by the Board of Directors.

                                                                              19

10.  EMPLOYEE COMPENSATION PLANS (CONTINUED)

Pro forma information regarding net income and earnings per share, as if the
Company had used the fair value method of SFAS 123 to account for stock options
issued under its equity incentive plan is presented below.  The fair value for
these options was estimated at the date of grant using the "minimum value
method" prescribed by SFAS 123.  The following weighted-average assumptions were
used to determine the fair value for 1997, 1996 and 1995, respectively: a risk-
free interest rate of 6.08%, 6.2% and 6.0%, an expected dividend yield of 0%
each year, and a weighted-average expected life of the options of six years.

</TABLE>

At December 31, 1997, the Company had net operating loss carryforwards for
federal income tax purposes of approximately $9,151,000 which expire through the
year 2012.  The utilization of net operating losses may be subject to limitation
under the change in stock ownership rules of the Internal Revenue Code.  For
financial reporting purposes, a valuation allowance of approximately $3,400,734
has been recognized to offset the deferred tax assets, including these
carryforwards, since uncertainty exist with respect to future realization of
such carryforwards.  The 1997 increase in the valuation allowance of $1,290,750
is comprised of an increase in the allowance of $2,197,154 relating to the
creation of deferred tax assets in the current period that may not be realized
in future periods, and a decrease of $906,404 relating to the utilization of a
portion of these deferred tax assets to offset acquired deferred tax liabilities
unable to be offset by preacquisition deferred tax assets.

12.  CONTINGENCY

On June 12, 1997, Jay N. Greenberg, a founder and former executive vice
president of the Company, filed a complaint against the Company in Massachusetts
state court seeking damages of $1.4 million and a declaratory judgement that
843,750 of the shares registered in Mr. Greenberg's name (out of 1,012,500
shares of class A Common Stock originally granted to Mr. Greenberg) have
"vested" under his employment agreement.  The complaint involves a dispute over
whether an amendment in December 1996 to Mr. Greenberg's employment agreement is
valid and whether Mr. Greenberg resigned or was terminated in January 1997.  The
Company maintains that the amendment was fraudulently induced based upon a
commitment by Mr. Greenberg for long-term employment with the Company and that
Mr. Greenberg resigned in January 1997.  Under such facts, Mr. Greenberg is
entitled to have no more than 450,000 shares of Class A Common Stock (and,
depending upon counterclaims that may be brought by the Company, possibly fewer)
and is entitled to no severance payment.  Mr. Greenberg claims that 843,750
shares of Class A Common Stock have vested and that his employment was
terminated in January 1997 by the Company entitling him to severance payments of
$440,000.  While the Company is not able to predict the outcome of this
litigation, it does not believe its ultimate resolution will materially affect
either the Company's financial position or its results of operations.

13.  SUBSEQUENT EVENT

In February 1998 the Company entered into affiliation arrangements with 2
physicians located in the Baltimore/Annapolis, Maryland area. The aggregate
total consideration paid to the physicians in connection with the affiliation

                        WAIVER OF RIGHTS AND AMENDMENT
                         UNDER STOCKHOLDERS AGREEMENT


     This Waiver of Rights and Amendment under Stockholders Agreement ("Waiver
of Rights") is made and entered into as of December 11, 1996, by and among
Physicians Quality Care, Inc., a Delaware corporation (the "Company"), and each
of the undersigned parties (the "Majority Stockholders").  Capitalized terms not
defined herein shall have the meanings set forth in the Stockholders Agreement
(as hereinafter defined).

     WHEREAS, the Company and the Majority Stockholders, along with certain
other holders of the Company's securities, are parties to a Stockholders
Agreement dated as of August 30, 1996, as amended and in effect from time to
time (the "Stockholders Agreement");

     WHEREAS, the Majority Stockholders collectively hold a majority of all
Shares currently outstanding and subject to the Stockholders Agreement and
collectively hold a majority of the Non-Bain Investor Shares currently
outstanding and subject to the Stockholders Agreement;

     WHEREAS, each of the physicians listed on Exhibit A (the "Non-Retiree
                                               ---------                  
Flagship Physicians") are becoming parties to the Stockholders Agreement for all
purposes by executing an Instrument of Joinder to Stockholders Agreement dated
as of even date herewith; and

     WHEREAS, pursuant to the provisions of Section 12.2 of the Stockholders
Agreement, the Company and the Majority Stockholders desire to waive certain of
the Company's rights under the Stockholders Agreement as set forth below.

     NOW, THEREFORE, the parties to this Waiver of Rights agree as follows:

1.   As applied to each of the Non-Retiree Flagship Physicians, Section 5.1.1.
     of the Stockholders Agreement is hereby amended to read in its entirety as
     follows:

               5.1.1.   Termination by the Company Without Cause.  If such
                        ----------------------------------------          
          termination is the result of termination of such holder's employment
          by the Company, its Subsidiaries or any Affiliate thereof without
          Cause or as a result of the death or Disability (as defined in such
          holder's written employment agreement with the Company, its Subsidiary
          or its Affiliate, as applicable (the "Employment Agreement")) of such
          holder, the Company (or its designee), upon written notice delivered
          within 90 days of termination, may purchase all or any portion of the
<PAGE>
 
          Shares, Warrants and Options then held by the applicable Call
          Stockholder Group at a price equal to the Fair Market Value of such
          securities; provided, however, that upon termination of the employment
                      --------  -------                                         
          by the Company, its Subsidiary or any Affiliate thereof of a holder of
          Physician Shares as a result of a Disability of such Physician
          Stockholder, the Company shall have no right to purchase all or any
          portion of the Shares, Warrants and Options then held by the
          applicable Call Stockholder Group for such period of time, if any, as
          such Physician Stockholder is in all respects a Qualified Holder with
          a Total Disability, as hereafter defined.

                    5.1.1.1.  It shall be the responsibility of such Physician
          Stockholder or his/her legal guardian, if any, to notify the Company
          in writing within 30 days of termination of employment as a result of
          Total Disability that such Physician Stockholder should be considered
          a Qualified Holder with a Total Disability and the failure of the
          Physician Stockholder or his/her legal guardian to do so in a timely
          manner shall be determinative of the matter.   Following said notice,
          the Physician Stockholder (in the case of seeking such qualification
          pursuant to Section 5.1.1.3(d)(i), upon the Company's request, or in
          the case of seeking such qualification pursuant to Section
          5.1.1.3(d)(ii), upon the request of the NMA Board (as defined below in
          Section 5.1.1.3(d)(ii)) shall submit to the examination and testing of
          up to three physicians selected by the Company or the NMA Board,
          respectively.  In order for the Physician Stockholder to be medically
          certified as having a Total Disability hereunder pursuant to Section
          5.1.1.3(d)(i), each of the physicians so selected must conclude that
          the Physician Stockholder has a Total Disability in accordance with
          Section 5.1.1.3(d)(i) hereof.  In the case of Physician Stockholders
          who qualify as Totally Disabled hereunder pursuant to Section
          5.1.1.3(d)(i), the Company may require the Physician Stockholder to be
          recertified quarterly thereafter by up to three physicians and the
          Physician Stockholder shall be recertified only by unanimous
          determination of the physicians selected by the Company.  In the case
          of Physician Stockholders who qualify as Totally Disabled hereunder
          pursuant to Section 5.1.1.3(d)(ii), the NMA Board may require the
          Physician Stockholder to be examined by a physician from time to time
          as the NMA Board determines appropriate but in no event more
          frequently than annually.  If the Physician Stockholder shall fail to
          submit to any medical examination or testing requested by the Company
          or the NMA Board hereunder, the Physician Stockholder shall cease to
          be a Qualified Holder with a Total Disability.

                    5.1.1.2.  A Physician Stockholder shall notify the Company
          in writing immediately if the Physician Stockholder ceases, in any
          respect, to be a Qualified Holder with a Total Disability in
<PAGE>
 
          accordance with Section 5.1.1.3(c) hereof.  Any Physician Stockholder
          who is determined to be a Qualified Holder with a Total Disability
          hereunder shall no longer qualify as such in the event that the
          Physician Stockholder ceases to meet in full all of the criteria set
          forth in Section 5.1.1.3(c) hereof.  The date on which the Company
          determines, and provides notice of such determination to the Physician
          Stockholder, that such Physician Stockholder ceases to be a Qualified
          Holder with a Total Disability shall be the "Disqualification Date".
          In the event a Physician Stockholder ceases to be certified or
          recertified as having a Total Disability or otherwise ceases to be a
          Qualified Holder with a Total Disability, the Physician Stockholder
          shall be treated for purposes of this Agreement as being terminated
          for Cause as of the Disqualification Date.

                    5.1.1.3.  Definitions.  For purposes of this Agreement, the
                              -----------                                      
          following definitions shall apply:

                    (a)  "Basic Activities of Daily Living" shall mean bathing,
          dressing, toileting, continence, eating and the ability to move from a
          sitting to a lying position and vice versa.

                    (b)  "Cognitive Impairment" shall mean confusion or
          disorientation resulting from a deterioration or loss of intellectual
          capacity as a result of Alzheimer's disease, senility or other
          irreversible dementia, which deterioration or loss is capable of being
          diagnosed, and is diagnosed, by standardized testing or instruments.

                    (c)  A "Qualified Holder with a Total Disability" shall mean
          a Physician Stockholder who (i) is Totally Disabled in accordance with
          Section 5.1.1.3 (d) hereof; (ii) is in compliance with and intends to
          remain in compliance with all of his/her obligations under the
          Employment Agreement (including without limitation the restrictive
          covenants), excluding only the Physician Stockholder's obligation to
          provide services thereunder; and (iii) is not working in any capacity,
          with or without compensation, whether as an employee, partner,
          independent contractor or otherwise.

                    (d)  A Physician Stockholder shall be certified as having a
          "Total Disability" by a physician selected by the Company hereunder
          only if (i) the Physician Stockholder (A) is unable to perform three
          or more of the Basic Activities of Daily Living without substantial
          human physical assistance and/or constant supervision or is suffering
          from a Cognitive Impairment and (B) is unable to work in any capacity,
          or (ii) in the event that (after having been examined in accordance
          with the requirements of and followed the procedures set forth in
          Section 5.1.1.1 above) the Physician Stockholder fails to be certified
<PAGE>
 
          as having a Total Disability pursuant to Section 5.1.1.3(d)(i), (A)
          the Physician Stockholder appeals to the National Medical Advisory
          Board of the Company (the "NMA Board"), and the NMA Board (by vote of
          the majority of all its members) certifies in its sole discretion that
          the Physician Stockholder is permanently disabled and is not able to
          contribute meaningfully as a member of the medical profession, and
          that such determination will not unfairly and adversely affect the
          other physician employees of the Company or its Subsidiaries or
          Affiliates and (B) the NMA Board (by vote of the majority of all its
          members) has not subsequently revoked such certification.

                                                                   -------------
                                 SERVICES AGREEMENT

     Services Agreement (the "Agreement") dated August 30, 1996, between
Physicians Quality Care, Inc., a Delaware corporation ("PQC"), with its
principal offices located at 950 Winter Street, Waltham, Massachusetts and
Medical Care Partners, P.C., a Massachusetts professional corporation ("MCP"),
with its principal offices located at 950 Winter Street, Waltham, Massachusetts.

     Whereas MCP engages in the provision of medical and surgical services
through its physicians and has agreed to provide certain services to such
physicians in connection with its employment of physicians pursuant to MCP's
General Terms and Conditions of Physician Employment in effect as of the date
hereof (the "Terms and Conditions"); and

     Whereas, MCP wishes to retain PQC to provide certain of such services on
MCP's behalf and PQC wishes to provide such services;

     Now, therefore, MCP and PQC hereby agree as hereinafter provided.

     1.  Terms defined in the Terms and Conditions and not otherwise defined
herein shall be used herein with the meanings so defined.

     2.  MCP hereby appoints and engages PQC to provide the services
contemplated by Article II of the General Terms and Conditions of Member
Physician Employment and PQC accepts such appointment and engagement on and
subject to the terms and conditions set forth in this Agreement.

     3.  In consideration for the services to be provided by PQC pursuant to
Section 2, MCP hereby assigns to PQC all amounts allocated to MCP, including
without limitation Stage One Gross Margins, Stage Two Gross Margins, Stage Three
Gross Margins and IHS Profits, pursuant to Article VII of the Terms and
Conditions.

     4.  PQC shall review the payables of MCP and shall cause payment thereof to
be made out of the funds of MCP.  All Operating Revenues and IHS Revenues shall
be deposited in a bank account maintained in the name of and owned by MCP with a
banking institution selected by PQC and approved by MCP, (the "Account") but
managed solely by PQC in accordance with the terms of this Agreement.  A
representative of PQC shall be the authorized signatory for the Account.  The
Shareholder of MCP shall also be, and MCP hereby appoints the Shareholder as, an
authorized signatory for the Account.  MCP covenants that it will not permit any
funds to be withdrawn from the Account except as authorized by PQC.  In addition
to billing, collecting and payment services, PQC shall manage the cash and cash
equivalents of MCP.

     5.  MCP hereby exclusively authorizes PQC to take the following actions for
and on behalf of and in the name of MCP throughout the term of this Agreement
and thereafter in accordance with Section 7:

          (a) bill, in MCP's name, under its provider number when obtained and

          number, bill, in the Physicians= names under their respective provider
          numbers and on their behalf, all claims (including co-payments due
          from patients) for reimbursement or indemnification from all other
          Managed Care Payors, fiscal intermediaries or patients for all covered
          items and services provided by MCP or by the Physicians to patients;

          (b) take possession of and endorse in the name of the Physicians or
          MCP, all cash, notes, checks, money orders, insurance payments, and
          any other instruments received as payment of accounts receivable (and
          MCP will cause an individual Physician who receives any payments for
          the benefit of MCP directly, to deliver such amounts promptly to PQC
          for deposit in the Account, and MCP covenants to transfer and deliver
          promptly to PQC for deposit in the Account, all funds received by MCP
          from patients or Managed Care Payors for medical services), all such
          funds to be deposited directly into the Account and to be applied in a
          manner consistent with this Agreement;

          (c) deposit all collections directly into the Account and to make
          withdrawals from the Account for such purposes as are consistent with
          this Agreement;

          (d) in MCP's name and on its behalf, and in the Physicians' names and
          on behalf of each of them, as necessary, collect and receive all
          accounts receivable generated by such billings and claims for
          reimbursement, place such accounts for collection, settle and
          compromise claims and institute legal action for the recovery of
          accounts; MCP shall cooperate fully with PQC in facilitating such
          collections and in collecting accounts receivable transferred to PQC
          for deposit in the Account by MCP, including endorsement of checks and
          delivery to PQC for deposit in the Account of all revenues in whatever
          form, received from patients or Managed Care Payors on their behalf,
          and completion of all forms necessary for the collection of said
          monies; and

          (e) sign checks on behalf of MCP and make withdrawals from the
          Accounts for payments specified in this Agreement and as requested
          from time to time by MCP for purposes not inconsistent with this
          Agreement.

     In addition to the foregoing, MCP, to the extent not prohibited by law,
hereby grants to PQC an exclusive power of attorney and appoints PQC its
exclusive true and lawful attorney in fact to take each of the actions specified

more powers of attorney naming PQC as its or their, as the case may be,
exclusive true and lawful attorney in fact) as may be necessary or desirable to
evidence or effect the authority or the power of attorney or both granted to PQC
pursuant to this Section.

     6.  This Agreement shall continue in effect for forty (40) years commencing
with the date of this Agreement as noted above.  Unless terminated earlier as
provided for in section 7 of this Agreement, the term of this Agreement shall be
automatically extended for additional terms of five (5) years each.

     7.  Termination.

          (a)  Termination on Default.

               i.   Either party shall be entitled to terminate this Agreement
                    if the other party fails to perform in any material respect
                    any material obligation required of it hereunder, and such
                    default continues for sixty (60) days after the giving of
                    written notice by the non-defaulting party, specifying the
                    nature and extent of such default; provided, however, that
                                                       -----------------      
                    the non-defaulting party shall not be entitled to terminate
                    this Agreement if the defaulting party commences the cure of
                    such default within the first sixty (60) day period and
                    thereafter diligently and in good faith continues to cure
                    such default until completion.

               ii.  Termination at election of PQC.  PQC shall be entitled to
                    terminate this Agreement upon written notice to MCP if:

                    (x)  a law firm with nationally recognized expertise in
                         healthcare law and acceptable to PQC and the Joint
                         Policy Board renders an opinion to PQC, with a copy
                         provided to the Joint Policy Board stating that a
                         material provision of this Agreement is in violation of
                         applicable law, and the parties do not agree to amend
                         this Agreement pursuant to Section 10 to cure such
                         violation; or

<PAGE>
 
                    (y)  any court or regulatory agency enters an order finding
                         a material provision of this Agreement is in violation
                         of applicable laws; or

                    (z)  PQC is prevented by MCP or any person under the MCP's
                         direction or control, from entering any of the
                         Physician Responsibility Centers, and such inability to
                         enter such premises continues for more than forty-eight
                         (48) hours after notice thereof to the Joint Policy
                         Board.

               iii. Termination by MCP. MCP may terminate this Agreement if and
                    only if such termination has been approved by the Joint
                    Policy Board and:

                    (x)  upon written notice to PQC of the failure of PQC to
                         make any payments required under this Agreement when
                         due and continued failure to pay such compensation
                         after thirty (30) days notice of such failure to PQC
                         unless the amount of such payment is being contested in
                         good faith; or

                    (y)  a law firm with a nationally recognized expertise in
                         health care law and acceptable to PQC and the Joint
                         Policy Board renders an opinion to MCP, with a copy
                         provided to the Joint Policy Board, stating that a
                         material provision of this Agreement is in violation of
                         applicable law, and the parties do not agree to amend
                         this Agreement pursuant to Section 10 hereof to cure
                         such violation; or

                    (z)  any court or regulatory agency enters an order finding
                         a material provision of this Agreement is in violation
                         of applicable laws.

          pursuant to this Section 7:

               i.   PQC and MCP shall cooperate and continue to perform their
                    obligations under this Agreement as may be necessary to

               ii.  MCP and PQC shall cooperate to ensure the appropriate
                    billing and collection for all health care items and
                    services provided by MCP prior to the effective date of

                    extent of funds advanced by PQC for the purchase of such
                    inventory.

               v.   Provisions of this Agreement shall survive any termination
                    if so provided herein or if necessary or desirable fully to
                    accomplish the purposes of such provision.

     8.  All notices required or permitted under this Agreement shall be in
writing and shall be deemed effective upon personal delivery or upon deposit in

     9.  This Agreement constitutes the entire agreement between the parties
and supersedes all prior agreements and understandings, whether written or oral,
relating to the subject matter of this Agreement.

    10.  This Agreement may be amended or modified only by a written instrument
executed by PQC and MCP, provided, however, in the event (a) any state or
                         -----------------                               
federal laws or regulations, now existing or enacted or promulgated after the
Effective Date are interpreted by judicial decision, a regulatory agency, or
legal counsel in such a manner as to indicate that this Agreement or any
provision hereof may be in violation of such laws or regulations, or (b) the
Financial Accounting Standards Board or other applicable accounting standard
setting entity promulgates standards that would prevent PQC from consolidating
for financial statement presentation purposes all revenues of MCP on PQC's
consolidated financial statements, then PQC shall propose to the Joint Policy
Board and the MCP Shareholder for their approval such amendments to this
Agreement as necessary to preserve the underlying economic and financial
arrangements between PQC and MCP and without substantial economic detriment to
either PQC or MCP.  Any such amendment approved by the Joint Policy Board and
MCP Shareholder shall be binding upon MCP, and MCP hereby consents to any such
amendment.  To the extent any act or service required of PQC should be construed
or deemed, by any governmental authority, agency or court, to constitute the
practice of medicine by PQC, the performance of said act or service by PQC shall
be deemed waived and forever unenforceable and the provisions of this Section 10
shall be applicable.  MCP hereby waives and agrees not to assert illegality as a

                                      -5-

defense to the enforcement of this Agreement or any provision hereof; instead,
any such purported illegality shall be resolved pursuant to the terms of this
Section 10.

     11.  This Agreement shall be construed, interpreted and enforced in
accordance with the laws of The Commonwealth of Massachusetts.

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

                           FLAGSHIP HEALTH II, P.A.
                              SERVICES AGREEMENT

     This Agreement (this "Agreement") is made as of November 30, 1996,
and amended and restated as of July 31, 1997, by and among Physicians Quality
Care, Inc., a Delaware corporation ("PQC"), Flagship Health II, P.A., a Maryland
Professional corporation ("Flagship II") and Flagship Health, P.A., a Maryland
professional association ("Flagship I" and collectively with Flagship II,
"Medical Group").  (All capitalized terms not defined below in this Agreement
shall have the meanings set forth in Appendix A or B attached hereto.)

     WHEREAS, Medical Group has entered into a business arrangement with PQC in
order to help effectuate the parties' mutual vision of establishing a high
quality, competitive, cost-effective health care delivery system, as part of
which Medical Group and PQC will work together to enhance the efficiency of the
business aspects of Medical Group's practice, to promote the quality of care and
patient satisfaction, and to create sufficient economies of scale to permit
Medical Group to undertake risk-based managed care obligations;

     WHEREAS, Medical Group engages in the provision of medical and surgical
services through its physicians (each a "Medical Group Physician" and
collectively the "Medical Group Physicians"), who currently practice in a number
of divisions (each a "Pod"), each of which may have one (1) or more Practice
Locations; and

     WHEREAS, Medical Group wishes to retain PQC to provide or arrange for
comprehensive management, administrative and other support services to manage
Medical Group and each Pod in order better to serve its patients, enhance
efficiency, and improve financial results of operation of the Medical Group's
activities.

     NOW, THEREFORE, in consideration of the mutual covenants and premises
herein contained, the parties hereby agree as follows:

     1.  APPOINTMENT OF PQC; RETENTION OF CLINICAL AUTHORITY

     1.1  Appointment and Authority.   Medical Group hereby appoints and
          -------------------------                                       
engages PQC as Medical Group's sole and exclusive business manager and PQC
accepts such appointment and engagement on and subject to the terms and
conditions set forth in this Agreement.  Subject to the terms of this Agreement,
including applicable requirements of consultation and prior approval of the
Joint Policy Board, PQC shall have the authority and responsibility to: (i)
manage all business operations of Medical Group in an efficient and cost-
effective manner; (ii) provide or arrange for such services in any manner as
PQC, in the exercise of its reasonable business judgment, deems appropriate to
meet the day-to-day requirements of the business functions of Medical Group; and
(iii) negotiate and execute, on behalf of Medical Group, all contracts that, in
the exercise of PQC's reasonable business judgment, are necessary and
appropriate for the business and affairs of Medical Group, subject, in the case
of Payor Contracts, to the approval of the Joint Policy Board.

                                      -1-
<PAGE>
 
     1.2  Retention of Authority.  Notwithstanding anything to the contrary in
          ----------------------                                                
this Agreement, Medical Group will have exclusive authority and control over the
provision of medical services, including all diagnoses, treatment and ethical
determinations with respect to patients.  All diagnoses, treatments, procedures
and other medical and professional services shall be provided and performed
exclusively by or under the supervision of a physician employed or otherwise
engaged by Medical Group who meets the qualifications set forth in this
Agreement.  It is acknowledged that PQC is not authorized nor qualified to
engage in any activity that constitutes the practice of medicine.  To the
extent, if any, that any act or service of PQC under this Agreement is
determined to constitute the practice of medicine, the performance of such act
or service by PQC shall be deemed waived and excused by Medical Group.

     2.  OBLIGATIONS OF MEDICAL GROUP

     2.1  Physician Personnel.  Medical Group, subject to oversight by the
          -------------------                                               
Medical Advisory Board, shall be solely responsible for all determinations with
respect to an individual physician concerning the recruitment, hiring,
termination, Credentialing, training and supervision of such physician.  PQC
shall not exercise any control over nor have any responsibility for Medical
Group Physicians or other Clinical Staff (as defined in Section 2.5) with
respect to the provision of clinical services.

     2.2  Credentialing of Medical Group Physicians.   Medical Group, through
          -----------------------------------------                            
the Medical Advisory Board, shall credential its physicians in conformity with
the requirements imposed under state and federal law and by the terms of any
third party payment agreement to which the Medical Group is bound.  Medical
Group shall assure that each Medical Group Physician at all times is: (i) duly
licensed to practice medicine by the applicable state within the Geographic Area
(as defined in Section 10.10 of Appendix A); and (ii) a member in good standing
of the medical staffs of hospitals designated from time to time by the Joint
Policy Board or as may be necessary in connection with the participation in one
(1) or more Payor Contracts negotiated on Medical Group's behalf by PQC.  No
physician other than those Medical Group Physicians who meet the requirements
and qualifications of this Agreement, including without limitation Section 2.3,
shall be permitted: (a) to use or occupy the Pod Practice Locations, except as
approved by the Joint Policy Board; or (b) except as may be required to assure
appropriate medical care (e.g., locum tenens coverage), to render services to
patients of Medical Group.  New physicians may be employed by Medical Group, or
physician groups or practices may be acquired by Medical Group, subject to
approval of the Joint Policy Board and the Medical Advisory Board.

     2.3  Employment and Engagement of Medical Group Physicians.
          -----------------------------------------------------   

          (a)  General.  During the term of this Agreement, Medical Group,
               -------                                                      
               through its Pods, shall operate and maintain a full-time practice
               of medicine providing primary care, medical and surgical
               specialty services and such other services as are agreed upon by
               the Joint Policy Board and PQC.  Medical Group shall engage a
               sufficient number of Medical Group Physicians to provide services
               to patients of Medical Group during the normal office hours of
               the Practice Locations and to provide after hours coverage for

                                      -2-
<PAGE>
 
               all patients of Medical Group whether on an inpatient or
               outpatient basis (it being agreed that the practice patterns in
               effect as of the Effective Date are acceptable to PQC and Medical
               Group); provided, however, that a Pod may close its practice to
               new patients for such period as the Joint Policy Board and
               Medical Advisory Board may determine to be necessary in the event
               the Pod has reached capacity.

          (b)  Pods.  Each Medical Group Physician hired or otherwise engaged
               ----                                                            
               by Medical Group shall be a member of a Pod and shall provide
               services at the Practice Locations associated with that Pod.

          (c)  Form of Agreements.  Medical Group shall maintain employment
               ------------------                                            
               agreements with all Medical Group Physicians (individually, an
               "Employment Agreement").  Such Employment Agreements shall be in
               substantially the form attached hereto as Annex A-1 with respect
               to Medical Group Physicians who are assigned to a Pod that was
               created prior to July 31, 1997 (each a "Founding Pod"), and in
               substantially the form attached hereto as Annex A-2 with respect
               to Medical Group Physicians who are assigned to a Pod that is
               created on or after July 31, 1997 (each an "Additional Pod"), in
               each case with such changes as may be agreed upon by PQC and
               Medical Group and approved by the Joint Policy Board.  Except as
               otherwise expressly provided in this Agreement, Medical Group
               shall not amend any Employment Agreements nor waive any rights
               thereunder without the prior written approval of PQC.  Except as
               otherwise expressly provided in this Agreement, Medical Group
               shall not offer, agree to or amend any salary, benefit or other
               compensation terms with a Medical Group Physician except as
               expressly approved by PQC in writing.

          (d)  Medical Group Physician Qualifications.  Medical Group shall
               --------------------------------------                        
               assure that each Medical Group Physician meets at all times each
               of the qualifications set forth in the approved form of
               Employment Agreement (subject to any exceptions that are approved
               by PQC and the Joint Policy Board in connection with individual
               Employment Agreements) and to any other qualifications reasonably
               established by the Medical Advisory Board and PQC.  In the event
               that any disciplinary, malpractice or other actions are initiated
               against any Medical Group Physician, the Medical Group, through
               the Medical Advisory Board, shall immediately inform PQC of such
               action and shall inform PQC of the underlying facts and
               circumstances.

     2.4  Licensing and Accreditation.  Medical Group, through the Medical
          ---------------------------                                       
Advisory Board, shall ensure that all Medical Group Physicians maintain such
licenses and certifications as are reasonably necessary for the provision of
medical services by Medical Group and all Medical Group Physicians in a manner
that complies with all laws and applicable third-party payor requirements.
Medical Group shall obtain and maintain such additional licenses and

                                      -3-
<PAGE>
 
accreditation as the Medical Advisory Board and PQC mutually determine are
advisable.  Medical Group shall conduct its medical practice in compliance with
all applicable laws and all applicable contractual requirements.

     2.5  Supervision and Direction of Clinical Staff.    (As used in this
          -------------------------------------------                     
Agreement, the term "Clinical Staff" shall mean nurses and any other non-
physician clinical personnel and shall not include Medical Group Physicians or
any other physician.) Medical Group Physicians shall supervise and direct the
Clinical Staff.  Medical Group shall assure that all Clinical Staff members
perform only those duties permitted by applicable law and regulation to be
performed by such personnel, and only under such supervision and in such a
manner as permitted by applicable law and regulation.

     2.6  Liability Insurance.  Medical Group shall assure that each Medical
          -------------------                                                 
Group Physician maintains in effect a policy of professional liability insurance
in accordance with the Medical Group Physician's employment agreement.  Medical
Group shall maintain in effect a policy of comprehensive general liability and
professional liability insurance in the minimum amount of $1,000,000 per
occurrence or claim and $3,000,000 annual aggregate, or such greater amount as
is required by the Joint Policy Board or by law, to cover Medical Group, Medical
Group Physicians and Clinical Staff.  In addition, Medical Group shall maintain
in effect (i) comprehensive general liability insurance with limits and a
deductible reasonably determined by PQC and the Joint Policy Board and (ii)
property damage insurance covering all Practice Locations and equipment with
limits and deductibles reasonably determined by PQC and the Joint Policy Board.
Each such policy shall name PQC as an additional insured.  As set forth in
Section 3.15, PQC shall be responsible for administering Medical Group's
insurance policies required under this Section 2.6.

     2.7  Medical Records.  Medical Group, through its Pods, shall maintain
          ---------------                                                    
and cause each Medical Group Physician to maintain accurate and complete patient
records in accordance with all applicable laws and regulations.  Such records
shall be maintained by Medical Group in a manner sufficient to enable PQC, on
behalf of Medical Group, to bill and collect for the services provided by
Medical Group and Medical Group Physicians.  Subject to the requirements of
applicable law, Medical Group shall permit PQC to access the patient records to
perform its duties under this Agreement, including, without limitation, billing
and collection services.  All patient medical records relating to services
rendered by Medical Group and Medical Group Physicians shall be and remain the
property of Medical Group.

     Medical Group hereby grants to PQC the exclusive right to develop and
commercialize any statistical data base or other quality assurance, utilization
review or medical management data base or software program derived from Medical
Group's medical records (collectively, "Medical Data") and agrees to include in
all patient consent forms a mutually agreeable provision permitting the
commercialization of such Medical Data; provided, however, that PQC shall in all
events delete or otherwise disguise any patient identifying information such as
the name or street address of a patient and comply with all applicable laws
concerning patient confidentiality.  If PQC determines to commercialize any
Medical Data derived solely from medical records of Medical Group, then PQC
shall offer to Medical Group a right of first refusal to participate in the
effort to commercialize such Medical Data on terms consistent with those set
forth in Section 3.17 with respect to the development of Integrated Health

                                      -4-

Services.  If PQC determines to commercialize any Medical Data derived from both
Medical Group and other PQC-managed physician practices, PQC shall offer to
Medical Group and the other PQC-managed practices a right of first refusal to
participate in the effort to commercialize such Medical Data.  The terms of such
commercialization between PQC, on one hand, and the Medical Group and the other
PQC-managed practices (the "Physicians' Share"), on the other hand, shall be
consistent with those set forth in Section 3.17 with respect to the development
of Integrated Health Services.   Prior to entering into any arrangement to
commercialize such Medical Data with the Medical Group and other PQC-managed
practices acting jointly, PQC shall solicit the advice of the Medical Advisory
Board, which may make a recommendation to PQC's National Medical Advisory Board,
concerning an allocation of Physicians' Share of revenue, expenses, profits and
losses from such commercialization between Medical Group and any other medical
group or entity also contributing data, software or other resources to the
commercialization effort.  Such allocation shall be made in a manner that is
fair and not inconsistent with PQC's legitimate business objectives and its
obligations to its shareholders.  The recommendation, if any, of the National
Medical Advisory Board shall be considered by PQC in reaching its determination
concerning any commercialization of Medical Data and the allocation of proceeds
thereof, but ultimate decision-making authority with respect to such
commercialization and any recommended allocation of proceeds thereof shall
remain exclusively within the discretion of the Board of Directors of PQC and
Medical Group shall have no right to any allocation of proceeds except and to
the extent, if any, authorized by the Board of Directors of PQC after
consultation as set forth in this Section 2.7.

     2.8  Assignment of Intellectual Property.  Medical Group hereby assigns
          -----------------------------------                                 
to PQC (i) any Intellectual Property rights that Medical Group acquires or
develops during the term of this Agreement and (ii) agrees to cause each Medical
Group Physician to assign to PQC such Intellectual Property rights as may be
specified in, and subject to the terms of, the applicable employment agreement,
as the case may be.

     3.  OBLIGATIONS OF PQC

     3.1  General.  Subject to Medical Group's control of the practice of
          -------                                                          
medicine, PQC shall have authority and responsibility to conduct, supervise and
manage the day-to-day business operation of Medical Group and shall be
responsible for providing the services set forth in this Section 3 to Medical
Group.  All services, facilities, furniture, fixtures and equipment provided by
PQC under this Agreement shall be in a manner consistent with community
standards for a medical practice of similar size.  Notwithstanding anything in
this Agreement to the contrary, the parties realize that development of
appropriate reporting systems for financial and utilization information and
similar tools designed to support the efficient management and development of
Medical Group should be a collaborative process between the parties, and
accordingly the parties agree to work together to develop such tools,
particularly during the initial months following the Effective Date.

     3.2  Facilities.  PQC shall arrange for Medical Group to use the premises
          ----------                                                            
at the locations listed on Schedule 3.2 which may be amended by PQC from time to
                           ------------                                         
time (collectively, the "Practice Locations"), subject to the terms of any
leases for the premises entered into from time to time by Medical Group or PQC,
as the case may be, and subject to approval of the Joint Policy Board.  PQC

                                      -5-
<PAGE>
 
shall provide or arrange for routine maintenance and cleaning services for the
Practice Locations required to cause the Practice Locations to satisfy the
standard set forth in Section 3.1.

     3.3  Equipment and Office Furnishings.  PQC shall arrange for Medical
          --------------------------------                                  
Group to have use of such equipment and office furnishings reasonably deemed
necessary by PQC, in consultation with the Joint Policy Board, for the operation
of Medical Group at each Practice Location (the "Equipment") in a manner
consistent with community standards for a medical practice of similar
characteristics.  PQC shall arrange for reasonable and necessary repair and
maintenance of the Equipment.  In connection with PQC's obligation hereunder,
Medical Group shall notify PQC immediately upon becoming aware of any Equipment
in need of repair.

     3.4  Personnel and Payroll.  PQC shall arrange for the provision to
          ---------------------                                           
Medical Group of all administrative personnel deemed necessary by PQC, in
consultation with the Joint Policy Board, for the operation of Medical Group
(the "Administrative Staff").  PQC shall also arrange for the provision to
Medical Group of all Clinical Staff reasonably deemed necessary by PQC, in
consultation with Medical Group and the Joint Policy Board, for the efficient,
professional operation of Medical Group.  All members of the Clinical Staff
shall be employees of Medical Group.  All members of the Administrative Staff on
the Effective Date shall be employees of Medical Group.  Subject to the
provisions of Section 2.5 and this Section and in consultation with Medical
Group and the Joint Policy Board, PQC shall be responsible for recruiting,
hiring, discharging and determining the compensation, benefits and conditions of
employment of the Administrative Staff and Clinical Staff.  PQC shall perform
all payroll and payroll accounting transactions for the Administrative Staff,
the Clinical Staff and the Medical Group Physicians.  Any member of the
Administrative Staff and Clinical Staff may, upon assignment by PQC following
consultation with the affected Pods, provide services to more than one (1) Pod.
If any Medical Group Physician is dissatisfied with the services of any employee
who provides services for such Medical Group Physician at a Practice Location,
PQC, after consultation with the Joint Policy Board, shall in good faith
determine whether the performance of that employee could be brought to
acceptable levels through counsel and assistance, or whether the employment of
such employee should be terminated.  If PQC determines to retain such employee
and the Medical Group Physician is still dissatisfied with such employee's
services after a two (2) month period, PQC shall either relocate such employee
or otherwise cease to use such employee unless PQC reasonably determines that
such termination may expose Medical Group to liability.

     3.5  Borrowings.
          ----------   

          (a)  All borrowings of Medical Group shall be subject to prior
               approval by the Joint Policy Board.  Upon receipt of such
               approval to borrow funds on behalf of Medical Group, PQC shall
               arrange for such borrowing on behalf of Medical Group on terms
               approved by the Joint Policy Board pursuant to Section 6. 1(b)(i)
               and in accordance with the Practice Expense definition set forth
               provisions in Section 10.27 of Appendix A.  In addition to or in

                                      -6-
<PAGE>
 
               lieu of the foregoing, and subject always to prior approval by
               the Joint Policy Board, PQC may make loans to Medical Group from
               time to time to fund capital expenditures or working capital of
               the Medical Group, in each case on such terms and conditions as
               are agreed upon by the parties and the Joint Policy Board.  The
               making of any such loan shall be at the sole discretion of PQC
               provided that PQC shall commit to fund loans for working capital
               purposes of the Medical Group in an amount determined from time
               to time by the Joint Policy Board which amount shall not exceed
               $1,000,000.

          (b)  In the event that during the Fiscal Periods ended December 31,
               1997 and December 31, 1998, Medical Group does not receive
               distributions with respect to a Founding Pod under Appendix B
               hereto equal to the full Baseline Amount (as defined in Section
               10.2 of Appendix A) (minus the amount necessary to pay all
               Deductible Expenses) due to (a) a failure by PQC to assist
               Medical Group in establishing additional revenue sources from
               services other than professional services so as to increase
               Practice Revenues, or (b) such other cause as may be approved by
               the Joint Policy Board, PQC shall loan to Medical Group with
               respect to the Founding Pods an amount not to exceed an aggregate
               of $1,000,000 at any one time outstanding on a non-interest
               bearing basis to cover such shortfalls in Baseline Amount, and in
               no event shall PQC Direct Expenses be included in determining
               whether a shortfall in Baseline Amount exists (the "Loan").  The
               Loan shall be carried on the balance sheet of Medical Group and
               shall be repaid in successive Fiscal Periods from the first
               available dollars of Net Margin allocable to Medical Group with
               respect to the Founding Pods.  In the event PQC undertakes a
               public offering of securities at any time prior to which the Loan
               has been repaid in full, the parties agree to consider in good
               faith whether interest on the Loan should be assessed at a fair
               market interest rate in order to comply with then applicable
               health care laws.

     3.6  Supplies and Inventory.  PQC shall be responsible for all inventory
          ----------------------                                               
systems of Medical Group at each Practice Location and for the ordering,
purchasing and maintenance of all supplies and inventory necessary for the
operation of Medical Group.  All drugs shall be purchased and maintained by
Medical Group or, at PQC's discretion and to the extent consistent with
applicable law, on behalf of Medical Group by PQC.

     3.7  Contracts.  PQC shall negotiate and administer contracts for
          ---------                                                     
equipment, materials, supplies and data processing services for the Medical
Group and for each Pod.  PQC shall seek, review, evaluate and negotiate Payor
Contracts on behalf of Medical Group.  Medical Group agrees to enter into and be
bound by all such Payor Contracts negotiated on its behalf by PQC; provided,
however, that any such Payor Contract must be approved in advance by the Joint
Policy Board in the manner contemplated by Section 6.1.  The Payor Contracts
listed on Schedule 3.7 shall be deemed to be approved by the Joint Policy Board.
          -------- ---
If required by applicable law, such contracts will be entered into in the name
of Medical Group.  PQC shall arrange for administrative support appropriate to
fulfill reporting requirements under Payor Contracts, such as eligibility
verification and financial and utilization reporting.

     3.8  Budgets.
          -------   

          (a)   General Preparation Principles.
                ------------------------------   

          (i)   PQC, acting through the Operating Manager in cooperation with a
                Physician representative (the "Representative") of the Pod,
                shall have responsibility for the preparation of budgets for
                each Pod (a "Pod Budget").

          (ii)  Each Pod Budget shall consist of an operating budget (revenues
                and expenses) and an annual capital expenditures budget,
                prepared on an accrual basis of accounting and in conformity
                with generally accepted accounting principles.

          (iii) PQC shall prepare, with input from the Joint Policy Board,
                budget guidelines ("Budget Guidelines") that PQC shall then
                follow in the preparation of each Pod Budget.  Examples of
                possible Budget Guidelines include but are not limited to the
                following:

                    (A)  each Pod Budget shall be constructed on management
                         policies that enable the Pod to achieve its financial
                         goals (profit from operations);

                    (B)  each Pod Budget shall provide specific detail
                         sufficient for the Pod Physicians and PQC to evaluate
                         and prioritize changes in programs and capital
                         expenditures;

                    (C)  each Pod Budget period shall be for a twelve (12) month
                         period ending December 31 or, for the initial Pod
                         Budget for each newly formed Pod, such shorter period
                         ending December 31 as is appropriate; and

                    (D)  each Pod Budget shall be prepared on a pre-physician
                         compensation, pre-management fee and pre-tax basis.

          (iv) PQC shall prepare the initial Pod Budgets for each Pod using
               available historical financial information.  PQC shall follow the
               Budget Guidelines and identify budget preparation assumptions
               that deviate from the acquired medical group's historical
               financial information.  Subsequent Pod Budgets shall be prepared
               in a similar manner by PQC (on the basis of the prior year's
               results) and take into account deviations from the Pod Budget
               that occurred in the prior year.

          (b)  Approval of Budgets.  The Joint Policy Board shall have the
               -------------------                                          
               responsibility for and authority to approve each Pod Budget.  PQC
               shall submit each Pod Budget to the Joint Policy Board for
               approval on a timely basis.  Once approved in accordance with
               this Section 3.8(b), all of PQC, Pod and Pod Physicians shall be

                                      -8-
<PAGE>
 
               bound by the terms of the approved Pod Budget for the following
               twelve (12) month period or such lesser period as may be provided
               for in the Budget Guidelines, subject only to any modifications
               suggested by PQC and/or Pod Physicians and approved by the Joint
               Policy Board.  At any point during a Fiscal Period, including for
               example if the actual Physician Pod Practice Revenues less actual
               Physician Pod Practice Expenses is below budgeted levels for such
               Physician Pod or if there is an actual or projected negative Net
               Margin the Joint Policy Board may review the budgets for such
               Physician Pod and make such changes to such budgets, including
               the aggregate Pod Distributions (as defined in Section 3 of
               Appendix A to the Employment Agreements), as the Joint Policy
               Board deems to be appropriate.  All capital and operating
               budgets, and changes thereto, also shall be subject to the
               approval of PQC.  The Joint Policy Board shall not unreasonably
               withhold its approval of a Pod Budget but if such approval is not
               forthcoming, the following process shall prevail so that the Pod
               may remain open to treat patients:

          (i)  If, prior to the commencement of any budget period, the Joint
               Policy Board has not yet approved the Pod Budget, then PQC and
               Medical Group will work diligently in good faith to obtain such
               approval.  Until such approval is obtained, the following
               procedures shall apply:

                    (A)  as to any disputed line items, the immediately
                         preceding budget period's Pod Budget shall be
                         controlling until such time, if any, as agreement is
                         reached on the amounts to be allocated to such disputed
                         line items, except that:

                         (1)  non-recurring extraordinary items shall not be
                              continued from the Pod Budget for the immediately
                              preceding budget period;

                         (2)  if items such as lease payments or payroll taxes
                              are subject to an automatic increase, such
                              increases shall be effective at the increased
                              rate; and

                         (3)  for items such as personnel salaries, the total
                              salary number shall be adjusted to take into
                              account changes in the number and classifications
                              of personnel members employed or contracted; and

                    (B)  as to any line items which are not in dispute, the new
                         Pod Budget submitted by PQC shall be effective for the
                         new budget period.

                                      -9-
<PAGE>
 
          (c)  Reporting.  PQC shall establish and administer the accounting
               ---------                                                      
               procedures and control for Medical Group and the Pods in
               accordance with generally accepted accounting principles.  PQC
               shall have the responsibility to prepare and submit to each Pod
               and to the Joint Policy Board as soon as practicable after the
               end of each month, but in any event within forty-five (45) days
               of the end of each month, management reports designed to convey
               Pod and Medical Group financial performance for the month and on
               a year-to-year basis.  PQC shall design the management reports to
               highlight actual financial performance and actual to budget
               variances in the Pod's financial performance.   Additionally, PQC
               shall from time to time attempt to identify, discuss with the
               Joint Policy Board and implement appropriate management
               intervention to counter adverse financial trends.

     3.9  Preparation of Tax Returns.  PQC shall prepare any and all required
          --------------------------                                           
tax returns of Medical Group but shall not have responsibility for preparation
of individual tax returns or other tax returns (e.g., IRS forms W-2s, 5500s,
etc.) for any Medical Group Physician or for any entity of which such Medical
Group Physician was a shareholder, partner, member, or employee prior to the
date of execution of this Agreement.

     3.10  Charges.  PQC shall advise Medical Group on the establishment,
           -------                                                         
maintenance and revision of a schedule of charges for physician services,
ancillary services, supplies, medication and all other services rendered by
Medical Group through each Pod.  Revisions to the fee schedule of a Pod must be
approved by the Joint Policy Board.

     3.11  Billing and Collection.  PQC shall provide or arrange for such
           ----------------------                                          
billing and collection services as are reasonably necessary to attempt to
collect in a timely manner all Practice Revenues, including without limitation
all allowable charges resulting from Medical Group's provision of all billable
items and services.

     3.12  Payment of Accounts and Indebtedness.
           ------------------------------------   

           (a) PQC shall review the payables of Medical Group and shall cause
               payment of any undisputed amounts thereof to be made out of the
               funds of Medical Group.  In addition to billing, collecting and
               payment services, PQC shall manage the cash and cash equivalents
               of Medical Group.

           (b) All Practice Revenues shall be deposited in one or more bank
               accounts maintained in the name of and owned by Medical Group
               (collectively, the "Medical Group Account") but managed solely by
               PQC in accordance with the terms of this Agreement and the
               applicable Pod's budgets.  A separate Medical Group Account shall

                                      -10-
<PAGE>
 
               be established for the Founding Pods (the "Founding Pod Medical
               Group Account") and the Additional Pods (the "Additional Pod

           -----------------------------------------                        
Affiliate shall provide Integrated Health Services in the Geographic Area unless
PQC gives Medical Group the option to be the exclusive provider of these
services, as provided in this Section.  To that end, if PQC or one (1) of its
Affiliates proposes to provide any Integrated Health Service in the Geographic
Area, PQC shall notify Medical Group and the Joint Policy Board of the nature of
the service and the terms upon which PQC or its Affiliate proposes to provide

such Integrated Health Services less all expenses attributable to such
Integrated Health Services, determined in accordance with generally accepted
accounting principles) shall be allocated between Medical Group and PQC, but to
the extent permitted by law in any event such proposal shall offer to Medical
Group the right to receive an allocation to the Variable Distribution Pool (as
defined in the Employment Agreements) of at least fifty percent (50%) of the net
revenues attributable to such Integrated Health Service provided that as a
condition thereof Medical Group shall agree that a percentage of any net loss
attributable to such Integrated Health Service equal to the percentage of net
revenues attributable to such Integrated Health Service shall be offset against
amounts otherwise allocable to Medical Group under Appendix B in any one (1) or
more Fiscal Periods thereafter occurring.  PQC agrees to use its reasonable
efforts to structure any proposal for the provision of Integrated Health
Services in the Geographic Region in a manner so that the allocation to Medical
Group contemplated by the forgoing sentence is in accordance with applicable
law.  Medical Group shall not agree to participate in any Integrated Health
Service or fail to elect to participate in such Integrated Health Service except
as approved by and on such terms as have been approved by the Joint Policy
Board.  If Medical Group does not elect to participate in such Integrated Health
Service in the Geographic Area within such forty-five (45) day period, PQC may,
but shall not be obligated to, provide such Integrated Health Service directly
or through another Affiliate or subsidiary (but in no event through or with any
outside third party without the prior consent of the Joint Policy Board) and
Medical Group shall have no right to participate in the revenues or income from
such Integrated Health Service; provided, however, that PQC shall not directly
                                --------  -------                             
or indirectly provide such Integrated Health Service if within such forty-five
(45) day period the Medical Advisory Board reasonably determines and notifies
PQC that the provision of such services have not been determined to be
clinically efficacious, are clinically dangerous, or would otherwise adversely
affect the reputation of PQC and/or Medical Group as to quality of care and;
provided, further, that PQC shall not directly or indirectly provide any
- --------  -------

Representatives on the Joint Policy Board voted against Medical Group
participating in such Integrated Health Service.

                    termination of an Employment Agreement pursuant to Sections
                    8(c)(i)(C), (F), (G), (K) or (L) of such Employment

                    other reason, including the reputation, financial results or
                    financial condition of Medical Group, may be made by the
                    Joint Policy Board without recommendation by the Medical
                    Advisory Board.

          (e)  Medical Advisory Board Recommendations Regarding New Physicians.
               ---------------------------------------------------------------  
               (i) Notwithstanding anything in this Section 6.1 to the contrary,
               the Joint Policy Board shall not authorize the employment of any
               additional physicians (other than in connection with the merger
               of a physician group into Medical Group) unless the Joint Policy
               Board shall have sought the recommendation of the Medical
               Advisory Board whether the addition of such physicians is
               advisable on the basis of the reputation and ability of the
               proposed physician and the compatibility of such physician with
               the existing Medical Group Physicians with the same area of

                                      -19-
<PAGE>
 
               practice.  In making its recommendation to the Joint Policy
               Board, the Medical Advisory Board shall consult with Medical
               Group Physicians in similar practice areas as the proposed
               additional physician.  If the Medical Advisory Board recommends
               the physician, the Joint Policy Board shall be free to approve an
               Employment Agreement with such physician.  If the Medical
               Advisory Board recommends that a physician not be approved by the
               Joint Policy Board, the Medical Advisory Board must recommend to
               the Joint Policy Board, within six months of the initial request
               by the Joint Policy Board, another physician with the same
               speciality or practice area and whose Baseline Net Adjusted
               Billings would be comparable to the physician proposed by the
               Joint Policy Board who is prepared to become a Medical Group
               Physician.  The Medical Advisory Board shall act expeditiously in
               considering whether to recommend any physician to the Joint
               Policy Board.  If the Medical Advisory Board fails to make such a
               recommendation within the six month period, the Joint Policy
               Board shall be free to offer employment to the physician
               originally proposed to the Medical Advisory Board if Medical
               Advisory Board recommended against such physician on the basis of
               lack of compatibility with existing Medical Group Physicians or
               the Medical Advisory Board made no determination.

          (ii) Notwithstanding anything in this Section 6.1 to the contrary, the
          Joint Policy Board shall not authorize the employment of any
          additional physicians in connection with the merger of a physician
          group into Medical Group unless the Joint Policy Board shall have
          sought the recommendation of the Medical Advisory Board whether the
          addition of such physicians is advisable on the basis of the
          reputation and ability of the proposed physician(s) and the
          compatibility of such physician(s) with the existing Medical Group
          Physicians with the same area of practice. The Medical Advisory Board
          must make a recommendation to approve or reject the employment of such
          physician(s) within 30 days of being advised of the proposed
          transaction. In reaching its recommendation, the Medical Advisory
          Board shall only consider the reputation and ability of the proposed
          physicians and the compatibility of such physicians with the existing
          Medical Group Physicians with the same area of practice. The Medical
          Advisory Board may consult with Medical Group Physicians in similar
          practice areas as the proposed additional physician. If the Medical
          Advisory Board recommends the physician(s) or fails to make a
          recommendation with the thirty-day period, the Joint Policy Board
          shall be free to approve Employment Agreement(s) with such
          physician(s).

          (f)  Voting; Procedures.
               ------------------   

               (i)  Each Medical Group Representative shall have one (1) vote
                    and shall have the right to grant his proxy to another

                    proxy to another member of the Joint Policy Board.  Except
                    as provided in clause (c)(ii) below, no action of the Joint
                    Policy Board shall be effective unless authorized by a
                    majority (or, in the case of matters set forth in Sections
                    6.1(c), by two-thirds) of the members of the Joint Policy
                    Board.  A quorum of the Joint Policy Board shall consist of
                    at least three (3) Medical Group Representatives and three
                    (3) PQC Representatives, present in person or by proxy;
                    provided, however, that if a meeting is called and a quorum
                    cannot be obtained within thirty (30) days of notice of such
                    meeting, then the quorum requirement shall be automatically
                    reduced for the first meeting thereafter to a majority of
                    the members of the Joint Policy Board, present in person or
                    by proxy.

               (ii) The Joint Policy Board shall meet from time to time when a
                    meeting is called by the chair or by three (3) or more
                    members of the Joint Policy Board upon at least five (5)
                    days' written notice to the other members of the Joint
                    Policy Board, which notice requirement may be waived with
                    respect to any member of the Joint Policy Board by the
                    attendance at such meeting.  The Joint Policy Board may also
                    hold meetings by telephone or act by written consent
                    according to procedures established by the Joint Policy
                    Board.  Minutes shall be kept of all formal actions taken by
                    the Joint Policy Board.  The Joint Policy Board may appoint
                    a secretary who is not a member of the Joint Policy Board.

     6.2  Medical Advisory Board.  A Medical Advisory Board shall be
          ----------------------

               work in conjunction with PQC in order to implement the policies
               established by the Joint Policy Board.  Such individual shall
               also be an employee of PQC.  Subject to the direction and
               supervision of the Medical Group Shareholder, the duties of the
               President shall include, without limitation:

          (i)  interfacing with representatives from the national corporate
               offices of PQC;

          (ii) implementing the business and strategic plans of Medical Group
               and overseeing the business operation of Medical Group; and

     The Medical Group Shareholder shall determine the salary and fringe

               amended to reduce the rights of the Medical Group Physicians
               under this section without the prior consent of a majority of the
               Physician Members), the Physician Members shall nominate by
               plurality vote three (3) candidates, who shall be Physician
               Members, for the position of President, and the Medical Group
               Shareholder shall select one (1) candidate from among such

               Medical Group Shareholder shall have the authority to appoint a
               person to serve as interim President until another person is duly

               as his responsibilities warrant full-time employment status.
               Notwithstanding the foregoing, the President shall be a Medical
               Group Physician active in the practice of medicine, until such
               time as the President's responsibilities warrant full-time

               remove the President at any time in the event that the employment
               agreement between the President and PQC is terminated, but in
               such event the position of President may be filled by Medical

               the position of President has been appointed in accordance with
               the provisions of this Section 6.3(b).   Medical Group shall
               assist in the development of procedures for the nomination,
               appointment and replacement of the President in such a manner as

               Members), the Physician Members shall nominate by plurality vote

               practice of medicine, until such time as the Medical Director's
               responsibilities warrant full-time employment status with the

          --------------------                                                 
permitted by this Agreement, Medical Group shall not provide any of the
additional services that have been approved by the Joint Policy Board and PQC as

(2) years after termination of this Agreement, except as permitted by this

          ------------------------------------------                            
Agreement and for a two (2) year period thereafter, Medical Group shall not
recruit, solicit or induce or attempt to induce, any employee or employees of
PQC to terminate their employment with, or otherwise cease their relationship
with, PQC.  During the term of this Agreement and for a one (1) year period

     8.4  Enforcement of Medical Group Physician Employment Agreements.
          ------------------------------------------------------------    
Medical Group shall enforce the Employment Agreements of Medical Group
Physicians, including, without limitation, restrictive covenants and liquidated
damages provisions contained in such agreements.  In the event that, after a
request by PQC, Medical Group does not pursue any remedy that may be available
to it by reason of a breach or default of the restrictive covenants and
liquidated damages provisions or any other provision of any Employment
Agreement, upon the request of PQC, and Medical Group shall assign to PQC such
causes of action and any other rights it has related to such breach or default
and shall cooperate with and provide reasonable assistance to PQC with respect
thereto.

     8.5  Remedies.  PQC and Medical Group acknowledge and agree that a remedy
          --------                                                              
at law for any breach or attempted breach of the provisions of this Section 8
shall be inadequate, and, therefore, either party shall be entitled to specific
performance and injunctive or other equitable relief in the event of any such
breach or attempted breach, in addition to any other rights or remedies
available to either party at law or in equity or under the Employment
Agreements, including without limitation provisions thereunder relating to the
repurchase by the Medical Group and/or the Medical Group Physicians of certain
assets.  Each party hereto waives any requirement for the securing or posting of
any bond in connection with the obtaining of any such injunctive or other
equitable relief.  If any provision of this Section 8 relating to the
restrictive period, scope of activity and the territory described therein shall
be declared by a court of competent jurisdiction to exceed the maximum time
period, scope of activity restricted or geographical area such court deems
reasonable and enforceable under applicable law, the time period, scope of
activity restricted and area of restriction held reasonable and enforceable by
the court shall thereafter be the restrictive period, scope of activity
restricted and the territory applicable to such provision of this Section 8.
The invalidity or non-enforceability of any provision of this Section 8 in any
respect shall not affect the validity or enforceability of the remainder of this
Section 8 or of any other provisions of this Agreement.

long as PQC retains the sole right to provide Management Services in connection
with all activities conducted by Medical Group at such hospitals and other
facilities and (ii) the services set forth on Schedule 9.1.  Except in
connection with any Integrated Health Services which PQC is permitted to provide
itself or through an Affiliate pursuant to Section 3.8 or except as two-thirds

Group or Clinical Associates on the Effective Date, including the management of
capitated contracts.  If during the term of this Agreement, either PQC or any
Affiliate proposes to establish an IPA in the Maryland Area, the terms set forth

          ------------                                                     
court of competent jurisdiction to be void, invalid or unenforceable, the same
will either be reformed to comply with applicable law or stricken if not so
conformable, so as not to affect the validity or enforceability of the remainder
of this Agreement.

     9.6  Waiver.  Failure of either party to enforce a right under this
          ------                                                          
Agreement will not act as a waiver of that right or the ability to later assert
that right relative to the particular situation involved.

           ------------------------------                                     
this Section 9.13, none of the obligations and duties of PQC or Medical Group

Agreements between the Medical Group Physicians and Medical Group, the Medical

     9.14  Contract Modifications for Prospective Legal Events.  In the event
           ---------------------------------------------------                 
(a) any state or federal laws or regulations, now existing or enacted or
promulgated after the Effective Date are interpreted by judicial decision, a
regulatory agency, or legal counsel with a nationally recognized expertise in
the field of law in question in such a manner as to indicate that this Agreement
or any provision hereof may be in violation of such laws or regulations, or (b)
the Financial Accounting Standards Board, Emerging Issues Task Force or other
applicable accounting standard setting entity promulgates standards or issues a
consensus that would prevent PQC from consolidating for financial statement
presentation purposes all Practice Revenues of Medical Group on PQC's
consolidated financial statements, then PQC shall propose to the Joint Policy
Board and Medical Group for their approval such amendments to this Agreement as

amendment approved by the Joint Policy Board and Medical Group shall be binding

any governmental authority, agency or court, to constitute the practice of
medicine by PQC, the performance of said act or service by PQC shall be deemed
waived and forever unenforceable and the provisions of this Section 9.14 shall
be applicable.  To the fullest extent permitted by law, Medical Group hereby
waives and agrees not to assert illegality as a defense to the enforcement of
this Agreement or any provision hereof, instead, any such purported illegality
shall be resolved pursuant to the terms of this Section 9.14.

     9.15  Availability of Certain Documents.  The parties agree, to the
           ---------------------------------

relating to the nature and extent of the costs of services hereunder for a
period of four (4) years after the provision of such services.

                                 DEFINITIONS

meanings set forth below:

     10.2.  "Affiliate" or "Affiliates" means with respect to any person, a
             ---------      ----------

Eight Million, Four Thousand, Six Hundred Fifty Six Dollars ($8,004,656).  The
Baseline Amount shall be adjusted from time to time as determined by the Joint
Policy Board and Medical Group (i) to reflect the addition of new Physicians to

Physician included in a Founding Pod or (ii) to reflect such other factors as

Baseline Net Adjusted Billings in an appendix to the Medical Group Physician's
employment agreement with Medical Group, which amount is based upon such

adjust such initial Baseline Net Adjusted Billings amount to reflect such
physician's actual Net Adjusted Billings as an employee of Clinical Associates
for the fiscal year ended June 30, 1997 as soon as such information is
available.  Baseline Net Adjusted Billings for a Medical Group Physician shall
also be adjusted by PQC for changes in practice patterns (i.e., weekly hours
worked, part time status), which changes shall be notified by Medical Group and
the Medical Group Physician to PQC immediately; provided that Baseline Net
Adjusted Billings shall be adjusted back in the event that the practice patterns
of the physicians return to their original status.   PQC shall be entitled to

percentage of fee for service billings declines by more than 5% compared to the

ended June 30, 1997; provided, however, that the amount of such reduction shall
only be equal to the excess of the actual percentage decline over 5%.  PQC shall
also be entitled, without the approval of the Joint Policy Board, to reduce the
Baseline Net Adjusted Billings of Medical Group Physicians engaged in a
specialist practice to reflect then current Net Adjusted Billings for such
Medical Group Physicians in the event that average fee for service collections
for such specialist Medical Group Physicians as a percentage of fee for service
billings declines by more than 5% compared to the percentage realized by such

outstanding capital stock of PQC or becomes entitled to exercise or exercises
management control of PQC pursuant to the terms of PQC's Articles of
Incorporation.

     10.7.  "Deductible Expenses" with respect to any Fiscal Period shall mean,

as of the Effective Date) for federal, state, local or other taxes attributable
to the merger into Medical Group (or attributable to taxable periods preceding
the merger) of any entity owned by one or more Medical Group Physicians
practicing in such Pod; provided, however that there shall be excluded any such
tax liability if and to the extent that Medical Group or PQC has received
payment from the Physician Members of the applicable Pod pursuant to the
indemnification provisions of any agreement of merger pursuant to which the said
merger has occurred; and provided, further that if any such Discretionary
Expense arises prior to an initial public offering of PQC stock, the Joint
Policy Board may recommend to PQC that it consider taking steps to finance such

                                 FOUNDING PODS
                                 -------------

     1.  General.  As set forth in greater detail below and subject to all of
         -------                                                             
the conditions and provisions hereof, the parties agree that the aggregate
compensation to be paid to PQC for services rendered under this Agreement with
respect to the Founding Pods shall equal the sum of (1) all PQC Direct Expenses
which are incurred in connection with the provision of services to Medical Group
and (2) additional compensation equal to fifty percent (50%) of Net Margin of
the Founding Pods.  This Appendix B-1 also provides for the priority of
application of Practice Revenues of the Founding Pods to various categories of
expenditures.

     2.  Application of Practice Revenues of the Founding Pods.
         ----------------------------------------------------- 

     Practice Revenues of the Founding Pods shall be applied to expenses and
other required distributions under this Agreement in the following order of
priority:

     (a) Step 1 - Practice Revenues of the Founding Pods shall be applied to pay
     --- ------                                                                 
Practice Expenses of the Founding Pods.

     (b) Step 2 - Any Gross Margin attributable to the Founding Pods remaining
     --- ------                                                               
after Step 1 above shall next be applied to payment of (i) the Baseline Amount
(minus the amount necessary to pay all Deductible Expenses of the Founding Pods)
and (b) PQC Direct Expenses on a proportional basis equal to the ratio of (i)
the Baseline Amount to (ii) PQC Direct Expenses  as approved by the Joint Policy
Board for the then current Fiscal Period or in the absence of approval of a
budget for the then current Fiscal Period, in the ratio set forth on Schedule B-
1 attached to this Agreement.  By way of example only and not as a limitation,
if the Baseline Amount is $12 million and budgeted PQC Direct Expenses allocated
to the Founding Pods are $1 million, then under this Step 2 12/13ths or 92.31%
of each dollar of Gross Margin shall be allocated to Medical Group for payment
of the Baseline Amount and the remaining 1/13th or 7.69% of each dollar of Gross
Margin shall be allocated to PQC.

     (c) Step 3 - After completion of Step 2, any remaining Net Margin
     --- ------                                                       
attributed to the Founding Pods shall be allocated fifty percent (50%) to
Medical Group for distribution to the Medical Group Physicians in the Founding
Pods and fifty percent (50%) to PQC as additional compensation hereunder.

     Subject to review by the Joint Policy Board, PQC shall calculate the
amounts of Gross Margin and Net Margin to be allocated to each of Medical Group
and PQC under this Section 2.  If the Gross Margin is negative in any Fiscal
Period, such negative amount shall constitute Practice Expenses of the Founding
Pods for the next following Fiscal Period.  In the event Net Margin is negative
in the Fiscal Periods ending December 31, 1997 or December 31, 1998, PQC may be
obligated to make a loan to Medical Group in accordance with the provisions of
Section 3.5 of the Agreement.

     3.  Payment of Physician Draw.  On a bi-weekly basis, PQC shall distribute
         -------------------------                                             
to Medical Group from the Founding Pod Medical Group Account referred to in
Section 3.12 of this Agreement  an amount equal to one twenty-sixth of the
budgeted aggregate Physician Draw (minus the amount necessary to pay all
Deductible Expenses) for distribution by Medical Group; provided, however, if
(a) at any time during a Fiscal Period, PQC determines that the amount of
Practice Revenues allocated to the payment of aggregate Physician Draw under
this Appendix B-1 for any Fiscal Period may be less than ninety-five percent
(95%) of the budgeted aggregate Physician Draw of Medical Group Physicians in
the Founding Pods for such Fiscal Period, or (b) if PQC or the Joint Policy
Board determines (1) the aggregate Practice Expenses of a Founding Pod for such
Fiscal Period will exceed the aggregate budgeted Practice Expenses of such
Founding Pod for such Fiscal Period, or (2) the aggregate Practice Revenues of a
Founding Pod will be less than the aggregate budgeted Practice Revenues of such
Founding Pod, PQC may, and upon direction from the Joint Policy Board, shall,
reduce the aggregate Physician Draw in such manner as PQC determines to be
appropriate.  Subject to the provisions of Section 3.5 of this Agreement, the
aggregate Physician Draw of Medical Group Physicians in the Founding Pods shall
be adjusted to reflect the addition of new Medical Group Physicians to a
Founding Pod or the termination or resignation of any Medical Group Physician
assigned to a Founding Pod or to reflect such other factors as PQC and the Joint
Policy board shall mutually agree to be appropriate.  PQC may, but shall not be
required to, advance money to the Compensation Pool as defined in Appendix A to
the Employment Agreement to fund such Physician Draw.

     4.  Payment of Variable Distribution Pool.  Within forty-five (45) days of
         -------------------------------------                                 
the end of each of the first three (3) calendar quarters in each Fiscal Period,
PQC shall advise Medical Group's Compensation Committee (as defined in
Employment Agreements) of the amount (the "Variable Distribution"), if any, of
Net Margin allocable to Medical Group under Section 2 of this Appendix B-1 that
has not been used, or is not reasonably anticipated by PQC to be needed for
Medical Group to fund, all amounts required to be funded by Section 3.  PQC
shall disburse to Medical Group from the Founding Pod Medical Group Account
referred to in Section 3.12 of this Agreement the amount of the Variable
Distribution, which shall be distributed to the Medical Group Physicians in the
Founding Pods in such manner consistent with law as is described in Section 4 of
Appendix A to the Employment Agreements.

     5.  Annual Reconciliation of Distributions.  Within sixty (60) days after
         --------------------------------------                               
the end of each year, PQC shall (i) total and report Practice Revenues and
Practice Expenses for each of the Founding Pods, (ii) total and report aggregate
Practice Revenues for all Founding Pods and aggregate Practice Expenses for all
Founding Pods, (iii) total and report PQC Direct Expenses, (iv) total and report
all amounts advanced as Physician Draws and Variable Distributions with respect
to the Founding Pods, (v) total and report the level of Gross Margin, whether
positive or negative, and (vi) total and report the level of Net Margin, whether
positive or negative (taking into account any adjustments necessary in the event
that distributions during the said Fiscal Period or any prior Fiscal Periods
have resulted in an over-advancement or under-advancement of funds).  Each
Founding Pod, as a Discretionary Expense of its Medical Group Physicians, may
inspect Medical Group's books and records and PQC's books and records in order
to verify the amount and proper calculation of the sums to be determined
hereunder.  PQC may not charge any Pod or Physician Member any access or similar
fee in connection with any request to review books and records.  If such

                                      B-2
<PAGE>
 
independent accounting presents a report identifying a departure in such
financial reports from generally accepted accounting principles, which departure
has had a material adverse effect on the revenues allocated to Physician Group,
PQC shall reimburse the Physician Members for the cost of such report.

     6.  Distribution in Event of Actual or Anticipated Negative Gross Margin.
         -------------------------------------------------------------------- 
In the event that for any calendar quarter, Gross Margin is a negative number or
in the event either party gives notice to the other that there is reason to
believe Gross Margin may be a negative number, PQC shall promptly propose a
remedial plan of action to the Joint Policy Board and the parties agree to
cooperate in good faith in order to implement such remedial plan or such other
corrective action as shall be approved by the Joint Policy Board.  At PQC's sole
discretion, PQC may elect to advance working capital funds to Medical Group in
such amounts and at such times, and from time to time, as PQC shall determine
necessary to satisfy aggregate Practice Expenses for all Founding Pods, such
advances to be treated as loans, the repayment of which shall be required in
accordance with the definition of "Practice Expenses" in Section 10.27 of
Appendix A hereto.  In the event PQC shall elect not to make advances sufficient
to satisfy aggregate Practice Expenses for all Founding Pods and Medical Group
has not otherwise satisfied Practice Expenses from its own resources, either
party shall have the right to terminate this Agreement upon thirty (30) days'
written notice.

     7.  Manner of Payment of Final Reconciliation.  Within seventy (70) days
         -----------------------------------------                           
after the end of the Fiscal Period, Medical Group and PQC shall make such
payments, if any, to each other as may be required under the provisions of this
Appendix B-1.  Medical Group covenants to distribute any amounts to the Medical
Group Physicians in a manner that complies with all applicable law.

     8.  Manner of Payment of PQC Direct Expenses and Compensation to PQC.  PQC
         ----------------------------------------------------------------      
shall arrange for the payment of PQC Direct Expenses and the compensation to PQC
itself in accordance with the terms of this Appendix and is hereby authorized to

staff and support services (including all PQC or Flagship support services)
included within Clauses (a) and (b) of the definition of Practice Expenses shall
not be deemed to be Practice Expense of Pod R to the extent, but only to the
extent, that the costs of such administrative staff and support services are in
excess of historical levels for Clinical Associates and such increase in costs
is specifically attributable to (x) services performed by such administrative
staff for Pods other than Pod R and not to the addition of physicians to Pod R
or change in the market costs for such services or labor rates or (y) additional
support services to which Pod R, acting reasonably, shall have objected at the
time  their implementation was proposed by PQC.

Medical Group Account

     9.  Allocation of Net Adjusted Billings to Medical Group Account.  Amounts
         -------------------------------------------------------------         
allocable to the Additional Pod Medical Group Account pursuant to paragraphs 2,
3, 4, 5, 6 and 7 (to the extent the allocation in made to the Additional Pods)
shall first be used to pay all Practice Expenses of the Additional Pods.  Any
amount remaining after the payment of Practice Expenses shall be available for
distribution to Medical Group Physicians in the Additional Pods.

     10.  Payment of Physician Draw.  On a monthly basis, PQC shall distribute
          -------------------------                                           
to Medical Group from the Additional Pod Medical Group Account referred to in
Section 3.12 of this Agreement an amount equal to one twelfth of the budgeted
aggregate Physician Draw of Medical Group Physicians in the Additional Pods
(minus the amount necessary to pay all Deductible Expenses) for distribution by
Medical Group; provided, however, if (a) at any time during a Fiscal Period, PQC
determines that the amount of Net Adjusted Billings allocated to the Additional
Pod Medical Group Account pursuant to this Appendix B-2 net of Practices
Expenses (the "Available Amount") for any Fiscal Period may be less than ninety-
five percent (95%) of the budgeted aggregate Physician Draw for such Fiscal
Period with respect to the Medical Group Physicians in the Additional Pods, or
(b) if PQC or the Joint Policy Board determines (1) the aggregate Practice
Expenses of an Additional Pod for such Fiscal Period will exceed the aggregate
budgeted Practice Expenses for such Additional Pod for such Fiscal Period, or
(2) the aggregate Net Adjusted Billings allocable to the Additional Pod Medical
Group Account with respect to an Additional Pod  will be less than the aggregate
budgeted Net Adjusted Billings allocable to the Medical Group with respect to
such  Additional Pod, PQC may, and upon direction from the Joint Policy Board,
shall, reduce the aggregate Physician Draw with respect to the Additional Pods
in such manner as PQC determines to be appropriate.  Subject to the provisions
of Section 3.5 of this Agreement, the aggregate Physician Draw with respect to
the Additional Pods shall be adjusted to reflect the addition of new Medical
Group Physicians to an Additional Pod or the termination or resignation of any
Medical Group Physician from an Additional Pod or to reflect such other factors
as PQC and the Joint Policy board shall mutually agree to be appropriate.  PQC
may, but shall not be required to, advance money to the Compensation Pool as
defined in Appendix A to the Employment Agreement to fund such Physician Draw.

                                      B-6
<PAGE>
 
     11.  Payment of Variable Distribution Pool.  Within forty-five (45) days of
          -------------------------------------                                 
the end of each of the first three (3) calendar quarters in each Fiscal Period,
PQC shall advise Medical Group's Compensation Committee (as defined in
Employment Agreements) of the amount (the "Variable Distribution"), if any, of
the Available Amount that has not been used, or is not reasonably anticipated by
PQC to be needed for Medical Group to fund, all amounts required to be funded by
paragraph 10.  PQC shall disburse to Medical Group from the Additional Pod
Medical Group Account referred to in Section 3.12 of this Agreement the amount
of the Variable Distribution, which shall be distributed to the Medical Group
Physicians in the Additional Pod in such manner consistent with law as is
described in Section 4 of Appendix A to the Employment Agreements.

     12.  Annual Reconciliation of Distributions.  Within sixty (60) days after
          --------------------------------------                               
the end of each year, PQC shall (i) total and report Net Adjusted Billings and
Practice Expenses for each Additional Pod, (ii) total and report aggregate Net
Adjusted Billings and Practice Expenses for all Additional Pods, (iii) total and
report all amounts advanced as Physician Draws and Variable Distributions with
respect to the Additional Pods.  Each Additional Pod, as a Discretionary Expense
of its Medical Group Physicians, may inspect Medical Group's books and records
and PQC's books and records in order to verify the amount and proper calculation
of the sums to be determined hereunder.  PQC may not charge any Pod or Physician
Member any access or similar fee in connection with any request to review books
and records.  If such independent accounting presents a report identifying a
departure in such financial reports from generally accepted accounting
principles, which departure has had a material adverse effect on the revenues
allocated to Physician Group, PQC shall reimburse the Physician Members for the
cost of such report and appropriate adjustments to the Additional Pod Medical
Group Account.

     13.  Manner of Payment of Final Reconciliation.  Within seventy (70) days
          -----------------------------------------                           
after the end of the Fiscal Period, Medical Group and PQC shall make such
payments, if any, to each other as may be required under the provisions of this
Appendix B-2.  Medical Group covenants to distribute any amounts to the
Physicians in a manner that complies with all applicable law.

     14.  Manner of Payment of Compensation to PQC.  PQC shall arrange for the
          ----------------------------------------                            
payment of  the compensation to PQC itself in accordance with the terms of this
Appendix B-2 and is hereby authorized to make withdrawals from the Medical Group
Account for such amounts at the time or times that the amounts become due.
Medical Group hereby authorizes PQC to make such withdrawals from the Additional
Pod Medical Group Account for compensation owed to PQC under the provisions of
this Appendix B-2 after termination of this Agreement.

                                                                   -------------


                                   AGREEMENT


    Agreement entered into as of November 30, 1997 by and among Physicians
Quality Care, Inc., a Delaware corporation ("PQC"), Flagship Health, P.A., a
Maryland professional association ("Flagship I"), Flagship Health II, P.A.
("Flagship II" and collectively with Flagship I, "Flagship"), and the physicians
listed on the signature page of this Agreement who are former stockholders and
optionholders (the "Stockholders") of Clinical Associates, a Maryland
professional association.

    This Agreement provides for certain understandings between the Stockholders,
PQC and Flagship in connection with the Amended and Restated Services Agreement
between PQC and Flagship and the Employment Agreements between each Stockholder
and Flagship.

    Now, therefore, in consideration of the representations, warranties and
covenants herein contained, the parties agree as follows.  Capitalized terms
used in this Agreement and not defined in this Agreement shall have the meaning
assigned to them in the Services Agreement.

    1.  Addition of Founding Medical Group Physicians to Additional Pod
        ---------------------------------------------------------------
Compensation Model.  The Services Agreement provides for a different
- ------------------                                                  
compensation methodology for the Founding Pods and the Additional Pods.  As a
part of their long-term business goals,  PQC and Flagship may determine that it
is in their best interest to merge the compensation arrangements of the Founding
Pods into the compensation arrangements for the Additional Pods.  While PQC and
Flagship shall have no obligation to do so, PQC and Flagship shall have the
right to amend the Services Agreement, including Appendices B-1 and B-2 thereto,
to merge the compensation arrangements of the Founding Pods into the
compensation arrangements for the Additional Pods; provided that such merger and
its material terms are approved by PQC and two-thirds of the Stockholders who
continue to be Medical Group Physicians at such time.  In the event that the
compensation arrangements for the Founding Pods and the Additional Pods are
merged, PQC shall provide a guarantee (which shall be in a form acceptable to
two-thirds of the Stockholders, acting reasonably) to the Stockholders that for
a two year period (commencing on the date of the merger of the compensation
arrangements for at least ten physicians in one or more Founding Pods into the
compensation arrangements for the Additional Pods) that the compensation of each
Stockholders who continues to be a Medical Group Physician will not be less than
the Physician Draw for such Stockholders as in effect at the time of such
merger; provided that the guarantee shall provide for reduction of the
guaranteed Physician Draw for the Stockholders  to reflect declines, if any, in
productivity and billing.  At the end of the two-year period covered by the
guarantee, the Services Agreement shall be amended, if requested by two-thirds
of the members of the Management Committee, to establish a separate Medical
Group Account and Compensation Pool with respect to Pod R.

    2.  Option to Amend Purchase Price.  Within six months after the Effective
        ------------------------------                                        
Date, the Stockholders, by the approval of two-thirds of the Stockholders, shall
have the right to elect to receive up to an additional 2,000,000 shares of Class
<PAGE>
 
A Common Stock of PQC (the "Common Stock") as additional consideration for the
merger of Clinical Associates into Flagship.  As a condition to receipt of such
additional shares, the Stockholders must agree to amend, effective upon delivery
of such Common Stock, the Services Agreement and their Employment Agreements so
that an additional $760,000 (or such proportionately reduced amount if less than
2,000,000 shares of Common Stock are elected) with respect to each fiscal year
is payable to PQC from the amount that would otherwise be allocated pursuant to
Appendix B-2 of the Services Agreement to the Additional Pod Medical Group
Account.

    3.  Right to Additional Compensation in the Event of a Shortfall.  With
        --------------------------------------------------------------     
respect to each fiscal year during the Shortfall Period (as defined below), the
amount that would have been allocated to PQC pursuant to Appendix B-2 of the
Services Agreement shall be reduced by the Adjustment Amount and the amount that
is allocated to the Additional Pod Medical Group Account shall be increased by
the Adjustment Amount; provided, however, that if with respect to any fiscal
year there is no Shortfall (as defined below) or PQC completes a public offering
of its Common Stock at a price to the public of $9.00 or more per share, this
Section 3 shall be of no further effect and no further adjustment shall be made
pursuant to this Section 3 during any subsequent fiscal year. "Shortfall Period"
shall mean every fiscal year commencing after December 31, 1997 to and including
the earlier of (i) the first fiscal year in which there is no Shortfall or (ii)
the fiscal year immediately preceding the date of the closing of a public
offering of Common Stock with a price to the public of $9.00 or more.
"Shortfall" shall mean the difference, if a positive amount, between $3 million
and the aggregate increase in Net Adjusted Billings over Baseline Net Adjusted
Billings by the specialist physicians in any Additional Pod; provided, however,
that there shall not be deemed to be a Shortfall in the event that there is less
than $3 million increase in Net Adjusted Billings because the specialist
physicians in the Additional Pods do not have the capacity to accept (unless the
Additional Pods are attempting in good faith to add physicians with the
applicable speciality and do add such additional capacity within six months of
notification from PQC), or were otherwise unwilling to accept (provided that PQC
shall give the Management Committee one month to cure any such unwillingness to
accept new patients if such refusals to accept new patients are isolated
occurrences and are not recurring), such referrals.  "Adjustment Amount" with
respect to any fiscal year shall be equal to (i) 45% of the Shortfall for such
fiscal year less the Laboratory Allocation.  The Laboratory Allocation with
respect to each fiscal year shall be equal to the Net Margin from Laboratory
Services allocated to Pod R under the Services Agreement.  The amount of any
Shortfall, Laboratory Allocation and Adjustment Amount shall be calculated as
soon as practicable after the end of each fiscal year.  Any reallocation on the
basis of an Adjustment Amount shall be made on or prior to the date that the
Additional Pod Medical Group Account is to be distributed to the physicians in
the Additional Pods under the Services Agreement.

    4.  Option to Sell Shares to PQC.  In the event that on the fourth
        ----------------------------                                  
anniversary of the Effective Date PQC has not completed an underwritten initial
public offering, each Stockholder shall have the right to require PQC to
repurchase the Common Stock issued to such Stockholder pursuant to the Merger
Agreement at a purchase price of $3.00 per share (subject to adjustment for

                                      -2-
<PAGE>
 
stock splits and combination).  PQC shall have the right to pay the purchase
price in the form of a five (5) year non-interest bearing note.  The principal
payable with respect to each such note issued to a Stockholder shall be reduced
each year that the note is outstanding by the amount, if any, that such
Stockholder=s compensation from Flagship during such year exceeds the
Stockholders' Physician Draw for such year.  The election to have PQC repurchase
the Common Stock must be made within 45 days of the fourth anniversary of the
Effective Date.

    5.  Board Representation.  PQC agrees that it will use its best efforts to
        --------------------                                                  
cause two physicians nominated by the Stockholders to be elected to PQC's Board
of Directors.  In addition, the Stockholders shall be entitled until such time
as PQC completes an initial public offering to appoint a representative who will
have the right to notice of and to be present at regularly scheduled meetings of
the PQC Board.

    6.  Management Services for Pod R.  PQC and Flagship agree that neither PQC
        -----------------------------                                          
nor Flagship shall materially change the billing methodology used on the
Effective Date with respect to Pod R or replace any senior level supervisory
personnel used on the Effective Date by Pod R in billing and collections without
the approval of a majority of the Members of the Management Committee.  PQC and
Flagship also agree not to replace the Flagship Chief Operating Officer or the
Medical Director without the approval of a majority of the members of the Pod R
Management Committee.

    7.  Operating Policies.  PQC and Flagship intend that the operating policies
        -------------------                                                     
set forth on Annex A to this Agreement will be adopted by the Joint Policy Board
as soon as practicable after the Effective Date.  PQC agrees that the PQC
Representatives to the Joint Policy Board will vote in favor of the adoption of
such policies.

    8.  Publicity Budget.  PQC and Flagship agree that the Flagship publicity
        --------------                                                       
budget for the first twelve months after the Effective Date shall be at least
$1,000,000, $250,000 of which shall be a Practice Expense of Pod R.

    9.  Pod R Management Committee.  The Stockholders agree that Pod R shall
        --------------------------                                          
establish a Management Committee that shall primarily be responsible for
overseeing the relationship between PQC, Flagship and the Medical Group
Physicians assigned to Pod R and for taking the actions expressly contemplated
by this Agreement.  The membership and rules governing the Management Committee
will be determined from time to time by the Medical Group Physicians assigned to
Pod R.  PQC and Flagship agree to work with Pod R in establishing the Management
Committee.

    10.  Certain Changes in Control.  PQC agrees that neither PQC nor Flagship
         -------------------------                                            
will  (i) merge or consolidate with or into, (ii) joint venture with, (iii) sell
or lease all or substantially all of their assets to, (iv) grant governance
participation to, (v) become managed by, or (vi) sell a controlling interest in
the stock of Flagship or PQC to,  a Baltimore Health Care Entity without the
approval of a majority of the members of the Management Committee.  A Baltimore

                                      -3-
<PAGE>
 
Health Care Entity means any hospital, medical group or other organization that
principally conducts its business in and derives its revenues from the delivery
of healthcare services in Maryland, but shall not include any physician group
that enters into an affiliation transaction with PQC.

    11.  No Third Party Beneficiaries.  This Agreement shall not confer any
         ----------------------------                                      
rights or remedies upon any person other than PQC, Flagship and the Stockholders
and their respective successors and permitted assigns.

    12.  Entire Agreement.  This Agreement (including the documents referred to
         ----------------

provided in Section 1.5(c), no Shares of the Company or Flagship shall be deemed
to be outstanding, and holders of certificates formerly representing Shares
shall cease to have any rights with respect thereto except as provided herein or
by law.

     1.11  Closing of Transfer Books.  At the Effective Time, the stock transfer
           -------------------------

financial and investment matters to be able to evaluate the risks involved in

in each case contained in this Agreement or the Stockholders Agreement;

<PAGE>
 
             (vi) any liability of the Company incurred prior to the Closing
Date that is not described in Schedule 2.8(a); and
                             ----------------     

             (vii)  any liability incurred by PQC or Flagship relating to
agreements or obligations of the Company or any Stockholder, whether written or
oral, that are not specifically identified on the Disclosure Schedule.

          (b) PQC and Flagship shall indemnify and hold harmless the Company and
the Stockholders and their respective agents or the successors of any of the
foregoing (collectively, the "Company Indemnified Parties") and together with
the PQC Indemnified Parties (the "Indemnified Parties"), and reimburse such
Company Indemnified Parties for, from, and against all Damages imposed on or
incurred by such Company Indemnified Parties which relate to or arise out of any
breach of any representation or warranty of, or covenant or agreement to be
performed by, PQC or Flagship, in each case contained in this Agreement.

     7.2  Method of Asserting Claims.
          -------------------------- 

          (a) An Indemnified Party shall give prompt written notice to an
indemnifying party (the "Indemnifying Party") of any payments, demands, claims,
suits, judgments, liabilities, losses, costs, damages or expenses (a "Claim") in
respect of which such Indemnifying Party has a duty to provide indemnity to such
Indemnified Party under this Article VII, except that any delay or failure so to
notify the Indemnifying Party only shall relieve the Indemnifying Party of its
obligations hereunder to the extent, if at all, that it is prejudiced by reason
of such delay or failure.

          (b) If a Claim is brought or asserted by a third party (a "Third-Party
Claim"), the Indemnifying Party shall assume the defense thereof, including the
employment of counsel reasonably satisfactory to the Indemnified Party and the
payment of all expenses.  The Indemnified Party shall have the right to employ
separate counsel in such Third-Party Claim and participate in the defense
thereof, but the fees and expenses of such counsel shall be at the expense of
the Indemnified Party.  In the event that the Indemnifying Party, within twenty
(20) days after written notice of any Third-Party Claim, fails to assume the
defense thereof, or in the event the Indemnifying Party fails to demonstrate, to
the reasonable satisfaction of the Indemnified Party, that it has sufficient
assets to meet its indemnification obligations hereunder, the Indemnified Party
shall have the right to undertake the defense, compromise or settlement of such
Third-Party Claim for the account of the Indemnifying Party.  Anything in this
Section 7.2(b) to the contrary notwithstanding, the Indemnifying Party shall
not, without the Indemnified Party's prior written consent, settle or compromise
any Third-Party Claim or consent to the entry of any judgment with respect to
any Third-Party Claim which would have any adverse effect on the Indemnified
Party, except as provided immediately below.  The

                                      -32-
<PAGE>
 
Indemnifying Party may, without the Indemnified Party's prior written consent,
settle or compromise any such Third-Party Claim or consent to entry of any
judgment with respect to any Third-Party Claim which requires solely money
damages paid by the Indemnifying Party and which includes as an unconditional
term thereof the release by the claimant or the plaintiff of the Indemnified
Party from all liability in respect of such Third-Party Claim.

          (c) With respect to any Claim other than a Third Party Claim, the
Indemnifying Party shall have thirty (30) days from receipt of written notice
from the Indemnified Party of such Claim within which to respond thereto.  If
the Indemnifying Party does not respond within such thirty (30) day period, the
Indemnifying Party shall be deemed to have accepted responsibility to make
payment and shall have no further right to contest the validity of such Claim.
If the Indemnifying Party notifies the Indemnified Party within such thirty (30)
day period that it rejects such Claim in whole or in part, the Indemnified Party
shall be free to pursue such remedies as may be available to the Indemnified
Party under applicable law.

     7.3  Survival.  All representations, warranties, covenants and agreements
          --------                                                            
made by the Parties herein or in any instrument or document furnished in
connection herewith shall survive the Closing and any investigation at any time
made by or on behalf of the Parties hereto.  All such representations and
warranties and the Stockholders' obligations pursuant to Section 7.1(a)(i) and
the obligations  of PQC and Flagship pursuant to Section 7.1(b) shall expire on
the third anniversary of the Closing Date, except for Claims, if any, asserted
in writing prior to such second anniversary, which shall survive until satisfied
in full or otherwise finally resolved.  The obligation of the Stockholders
pursuant to Section 7-1(a)(ii), (iii), (iv), (v), (vi) and (vii) shall survive
until six (6) months after the expiration of the applicable statute of
limitations with respect thereto.  All Claims and actions for indemnity pursuant
to this Article VII shall be asserted or maintained in writing by a Party hereto
on or prior to the expiration of such periods.

     7.4  Set-off and Recoupment.  Any amount or amounts due from any
          ----------------------                                     
Indemnifying Party to PQC under this Article VII may be paid to PQC, at PQC's
option, by set-off or recoupment against any amounts due to the Indemnifying
Party pursuant to this Agreement or pursuant to any agreement between the
Indemnifying Party and PQC, Flagship or any of their respective affiliates.  Any
such set-off will be without prejudice to PQC's right to pursue any other
remedies at law or in equity available to it.

     7.5  Limitation on Indemnification.
          ----------------------------- 

          (a)  Notwithstanding any other term or condition contained herein or
in any other agreement or instrument referred to herein, the indemnification
obligations 

                                      -33-
<PAGE>
 
of each Stockholder under Section 7.1(a)(i) - (vii) shall be limited, in the
aggregate, to the dollar value on the Closing Date of the Merger Consideration
paid to such Stockholder reduced by any amount deducted as a Deductible Expense
of such Stockholder under Section 10.4 of Appendix A of the Services Agreement
resulting from any Tax Liabilities of the Company, if, but only if, the Company
has filed all tax returns based on the good faith determination of its
accountants and paid all taxes shown to be due thereon through the taxable year
ending on the date of the Merger.

          (b) Notwithstanding any other term or condition contained herein, PQC
shall not be entitled to any indemnification pursuant to Section 7.1(a)(v), (vi)
or (vii) with respect to any Damages where the indenmitor (or in the case of the
Company, a member of the management committee) did not have knowledge of the
liability giving raise to such Damages prior to the Closing Date, if, and only
if, an amount equal to 100% of such Damages (subject to the limitation in
Section 7.5(a)) is included as a Practice Expense of Pod R pursuant to the
Services Agreement and PQC or Flagship, as in the case may be, is actually
reimbursed for 100% of such Damages (subject to the limitation in Section
7.5(a)) in accordance with terms of the Services Agreement.  Notwithstanding any
other term or condition contained herein, PQC shall not be entitled to any
indemnification pursuant to Section 7.1(a) with respect to the tax liability set
forth on Schedule 7.5(b) provided that PQC is reimbursed for such tax liability
         -------- ------                                                       
over a period of three years (or such longer period as the Internal Revenue
Service may agree) out of the Pod R Account as such term is defined in the
Services Agreement.

          (c) No Indemnified Party shall be indemnified and held harmless under
this Article VII from and against any Damages unless the Damages exceed on a
cumulative basis an amount equal to $250,000, in which case an Indemnitor shall
be liable only for Damages in excess of $250,000.  The foregoing limitation
shall apply to the Company, Stockholders, and Optionholders in the aggregate and
not individually.

<PAGE>
 
would be incapable of being satisfied by July 31, 1997; provided, that in any
case, a willful breach will be deemed to cause such conditions to be incapable
of being satisfied for purposes of this paragraph (b). Any breach on the part of
PQC or Flagship of the representations and warranties contained in Article III
or the covenants contained in Article IV, which permits termination of this
Agreement shall permit the Company, the Stockholders and the Optionholders to
immediately terminate any other agreement between PQC or Flagship and the

any of the conditions set forth in Article V would be incapable of being
satisfied by July 31, 1997; provided, that in any case, a willful breach will be

Stockholders, directors, officers or agents shall have any liability to the
other Parties, except for any deliberate breach or deliberate omission resulting

handling such information as it would exercise with similar information of its
own, and shall return any such information upon another Party's request.
