                                 PART I

ITEM 1.  BUSINESS

GENERAL

          Physicians Health Services, Inc., a Delaware corporation ("PHS" or the
"Company"), is the parent of three health maintenance organizations ("HMOs"):
(1) Physicians Health Services of Connecticut, Inc., a Connecticut corporation
("PHS/CT"), operating in Connecticut; (2) Physicians Health Services of New
York, Inc., a New York corporation ("PHS/NY"), operating in New York's
Westchester, Dutchess, Orange, Putnam, Rockland, Nassau and Suffolk Counties,
and the five boroughs of New York City; and (3) Physicians Health Services of
New Jersey, Inc., a New Jersey corporation ("PHS/NJ"), operating in New
Jersey. In addition, the Company is the parent of Physicians Health Insurance
Services, Inc. ("PHIS"), which is licensed in Connecticut as an insurance broker
to offer various insurance products, PHS Investments, Inc. ("PHSI"), the
Company's investment subsidiary, PHS Insurance of Connecticut, Inc.
("Insurance/CT"), which holds a health insurance license in the State of
Connecticut, Physicians Health Services Insurance of New York, Inc.
("Insurance/New York"), which holds a health insurance license in the State of
New York, Physicians Health Services (Bermuda), Ltd. ("Bermuda"), an insurance
company licensed as a reinsurer in Bermuda, and PHS Real Estate, Inc. ("PHSRE"),
a Delaware corporation which owns all of the outstanding stock of the Company's
one indirect subsidiary, PHS Real Estate II, Inc. ("PHSREII"), a Delaware
corporation which owns the Company's corporate headquarters in Shelton,
Connecticut. All of the aforementioned subsidiaries are wholly-owned, either
directly or indirectly, by the Company, except for PHS/NJ, in which MasterCare
Companies, Inc. ("MasterCare") holds a 20% minority interest. The Company is
federally qualified as an HMO throughout its Connecticut and New York service 
areas.

          The Company conducts substantially all of its operations through its
subsidiaries. Unless the context otherwise requires, the terms "Company and PHS"
refer to Physicians Health Services, Inc. and its subsidiaries. Its principal
offices are located at One Far Mill Crossing, Shelton, Connecticut 06484 , and
its telephone number is (203) 381-6400.

          The Company's managed care products include traditional HMO products,
in both open access and gatekeeper models, point of service ("POS") products,
administrative services only ("ASO") plans and Medicare and Medicaid plans.  The
Company's HMO subsidiaries contract for medical and related services with
individual practice associations ("IPAs"), physician hospital organizations
("PHOs"), physicians, physician groups, hospitals and other health care
providers.  The Company arranges for health care coverage for its members for a
fixed monthly payment, generally without regard to the frequency or extent of
health care services actually furnished, although small copayments may apply and
members pay a deductible and coinsurance in connection with the out-of-network
benefits in POS plans.

          As of January 1997, the Company had contracted with 23,298 providers
and 183 hospitals throughout its tri-state service area.  It had enrolled
400,021 members as of December 31, 1996 (424,940 as of January 1, 1997).


PRODUCTS

          The Company offers a broad assortment of managed care products. Its
POS products enable members to choose health care providers from the Company's
network of 23,298 providers and 183 hospitals or to obtain covered services
outside its network. The POS products combine the features of an HMO with the
features of an indemnity-type benefit for out-of-network utilization. Under the
POS plans, a member who obtains benefits outside of the PHS network pays a
deductible and coinsurance. As used herein, a plan with a POS out-of-network
benefit is referred to as a POS plan. The Company's traditional HMO plans
include a gatekeeper model HMO plan, which requires prior approval by a member's
primary care physician before the member may obtain the services of specialists
(the "Passport" plan), and an open access HMO plan in which members can obtain
services from all PHS participating physicians without the need for a referral
(the "Charter" plan). The Charter and Passport plans can be obtained as
traditional HMO plans or as the underlying HMO product for a POS plan. Under the
Company's traditional HMO plans, a member who selects a hospital or physician
from outside the network bears the entire cost of such services, unless the care
is related to an emergency or the member has received prior approval from the
Company.
<PAGE>
 
          The Company sells its products both on a proprietary basis and through
a joint marketing arrangement with The Guardian Life Insurance Company of
America ("The Guardian"). See "Business - Joint Marketing Arrangement with The
Guardian." Proprietary products are sold to medium and large size groups,
typically as one of several health care plans made available by the employer to
its employees ("alternative products"). Under the agreements with The Guardian,
jointly developed managed care products are marketed to existing customers of
The Guardian, as well as to new customers, under the tradename "Healthcare
Solutions". The Healthcare Solutions products are offered principally in the
small employer group market on a total replacement basis. Under this
arrangement, employees are offered the choice of traditional HMO products, POS
products, and, in certain cases, The Guardian indemnity products. Through the
first nine months of 1996, PHS and The Guardian shared profits and losses on the
Healthcare Solutions products through a combination of reinsurance and profit
sharing arrangements. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations". Effective October 1, 1996, the Company and
The Guardian converted all of the Healthcare Solutions products to a reinsurance
basis. As of October 1, 1996, the Company no longer shared profits and losses
with The Guardian with respect to indemnity products sold under the joint
marketing arrangement. The joint marketing arrangement covers PHS's New York,
New Jersey and Connecticut service areas.

          The Company offers third party administrator ("TPA") services for
administrative services only ("ASO") plans, Medicare risk and cost plans,
Medicaid plans, and individual plans in the New York service area. The Company
has a contract with the Mashantucket Pequot Tribe Employee Benefit Plan to
provide access to the Company's network of health care providers and utilization
management programs. In 1995, the Company began marketing plans to the small
group market through the Connecticut Business and Industry Association ("CBIA").
The Company is one of only four participants in the CBIA program. The Company
has a three-year contract with the Electric Boat Division of General Dynamics to
provide managed health care services to all of its salaried employees in
Connecticut. This contract was effective January 1, 1995 and has been recently
expanded to include the members of the Metal Trades Council Union. The Company
has a three-year contract to provide services to General Electric Company for
its employees in Connecticut. The General Electric plan, which was effective
January 1, 1996, combines elements of a fully insured HMO plan and an ASO plan.
Effective December, 1996, the Company initiated coverage for the New York State
Nurses Association Benefits Fund and its almost 29,000 members under a Charter
POS Plan.


HMO PLANS

          The Company's traditional HMO plans provide comprehensive health care
services to enrollees for a fixed monthly premium per enrollee, typically
charged to the enrollee's employer group, that does not vary with the nature,
frequency, or cost of services provided, although, where allowed by regulation,
premiums are age/sex adjusted according to the demographic characteristics of
the employer group.  Adjusted community rating, which includes factors related
to a specific employer's claims experience, is used with some of the Company's
larger accounts in certain of its service areas.  The Company is also able to
experience rate certain groups insured under its Healthcare Solutions products.
See "Business - Enrollment, Employer Groups and Marketing."  Under the
traditional HMO plans, the Company does not cover health care services provided
by non-participating physicians or other health care providers unless pre-
approval for an out-of-plan referral has been obtained or such services are the
result of a medical emergency.  Members are required to receive hospital care at
participating hospitals except for preauthorized out-of-plan referrals or
emergency admissions.  The traditional HMO benefit plans range from a plan with
limited copayments to a plan combining lower monthly premiums with higher
copayments paid by the member.  The plans provide coverage for physicians'
services, surgery, hospital care, x-ray and laboratory services, emergency care,
maternity services, well baby and other preventive health services and, to a
limited extent, skilled nursing, home health care, alcohol and drug
rehabilitation and mental health services.  The traditional HMO plans are
marketed to employer groups of all sizes, generally as alternative products.  As
of December 31, 1996, 33% of total membership was enrolled in traditional HMO
products (23.2% commercial enrollees, 1.6% ASO enrollees and 8.2% government 
enrollees).

                                       2
<PAGE>
 
          The Company's traditional HMO plans are the Charter and Passport
plans. The Charter plan is an open access model which permits members to use PHS
participating physicians generally without a referral or pre-authorization. The
Passport plan is a gatekeeper plan that the Company developed in response to
employer interest in such plans. Under the Passport plan, each member selects or
is assigned to a primary care provider, typically a family practice physician,
who is responsible for seeing that the member's medical needs are met. Use by
the Passport member of specialists for treatment typically requires a referral
by the primary care provider in order for the services to be covered.


POS PLANS

          POS Plans are marketed to all size employer groups as either a total
replacement or alternative product. Under a POS Plan, an enrollee chooses, at
the time of services, whether to use participating providers and hospitals, or
non-participating providers and hospitals.  If the enrollee chooses to use out-
of-network services, the enrollee is subject to deductibles, coinsurance and
claim forms.  The POS products have become increasingly popular because of the
freedom of choice afforded enrollees under such plans. The POS plans are wrapped
around the Company's traditional HMO plans so that an enrollee has the in-
network benefits of the Charter or Passport HMO plan. An enrollee who has a POS
Passport plan can elect to see participating or non-participating providers
without the customary prior referrals required in the Passport plan, in which
event such non-referred services are treated as out-of-network services.

          A significant portion of the Company's recent growth in membership has
occurred in its POS plans. As of December 31, 1996, 60.7% of total membership
was enrolled in POS products (51.1% commercial enrollees, 9.6% ASO enrollees).
Only 36% of total membership was enrolled in such plans at December 31, 1995.
The Company expects this trend to continue for the foreseeable future. See
"Management's Discussion and Analysis of Financial Condition and Results of
Operations - Cautionary Statement".


ASO PRODUCTS

          Under self-funded medical plans, the employer self-insures its health
care expenses and pays for health claims only as they are incurred, rather than
paying monthly premiums for insurance which covers the cost of medical services
as well as administrative expenses.  The Company, as a TPA, typically provides
claims processing and health care cost containment services through its provider
network and utilization management programs, and is paid a fee only in
conjunction with these administrative services.  The Company's ASO products
enable employers to access the Company's provider network and to realize savings
through certain of the Company's discounted fee arrangements and medical cost
containment capabilities, while allowing employers to design custom health
benefit plans in accordance with their own requirements and objectives.  Certain
of the Company's ASO products include performance guarantees.  See "Management's
Discussion and Analysis of Financial Condition and Results of Operations -
Cautionary Statement."  As of December 31, 1996, 16.9% of total membership was
enrolled in ASO products (9.6% in POS plans, 1.6% in HMO plans and 5.7% in the 
Mashantucket Peqout plan).

                                       3

MEDICARE/MEDICAID PRODUCTS

          The Company offers PHS/SmartChoice, a federal Medicare program, to
Medicare eligible individuals under the terms of risk contracts with the Health
Care Financing Administration ("HCFA"). PHS/SmartChoice is typically
marketed directly to individuals. The Company also offers PHS/SmartChoice as a 
POS product in the group market. It is currently offered in New York and
Connecticut. Enrollees in PHS/SmartChoice have limited copayments as long as
they use health care providers within the Company's network. PHS/SmartChoice
replaces both Medicare Part A and Part B coverage for enrollees and extends
coverage for preventive care, acute hospitalization and skilled nursing care. In
the PHS/SmartChoice gatekeeper product, in the event an enrollee chooses to
receive health care from a non-participating physician, neither PHS/SmartChoice
nor Medicare will cover the costs of such care absent an emergency or urgent
situation.

          Under its risk contracts with HCFA, the Company is paid a fixed per
member per month capitation amount by HCFA based upon a formula established by
HCFA establishing the projected cost to provide the covered services to each
Medicare member. The Company bears the risk that the actual costs of health care
services may exceed the per member per month capitation amount.

          Medicare risk contracts provide revenues that are generally higher per
member than those for non-Medicare members, and thus provide an opportunity for
increased profits and cash flow.  Such risk contracts, however, also carry
certain risks such as higher comparative medical costs, government regulatory
and reporting requirements, the possibility of reduced or insufficient
government reimbursement in the future, and higher marketing and advertising
costs per member as the result of marketing to individuals rather than to
groups.

          In Connecticut the PHS/SmartChoice product is intended to replace
another Medicare product (PHS/Carefree) formerly offered by the Company 
pursuant to a cost contract with HCFA. As of December 31, 1996, the Company had
9,638 members enrolled in PHS/Carefree. The Company anticipates that almost all
of these members will convert to the PHS/SmartChoice product by the end of 1997.

          The Company participates in Connecticut's Medicaid managed care
program pursuant to a contract with the Connecticut Department of Social
Services.  PHS had enrolled 20,781 members in this program as of December 31,
1996.  The Company receives fixed monthly premiums per member under the contract
with the Connecticut Department of Social Services and bears the risk that the
actual costs of health care may exceed the per member per month capitation
amounts received by the Company.  Medicaid plans also involve the risk of
reduced or insufficient government reimbursement and higher marketing and
advertising costs per member as a result of marketing to individuals rather than
to groups.  PHS has participated in the New York Medicaid managed care program
in Westchester County since February, 1994.  It contracts with Westchester
Prepaid Health Service Plans, Inc. for the provision of services under this
program.

          As of December 31, 1996, 9% of total membership was enrolled in a
government program, almost all in HMO plans.

                                       4

OTHER PRODUCTS

          The Company has entered into marketing arrangements with three
prominent HMO networks, UltraLink/SM/, HMO National Network/SM/ and National
Managed Care, Inc., to facilitate cooperative marketing efforts focusing on
national employer groups with employees in the Company's service area.  The
Company's affiliations with national networks allow it to compete with national
managed care companies for employers desiring a national managed care network.
In 1996, the Company generated almost $7 million in premium revenues from
employer groups accessing these national networks.  The Company has a multi-year
contract with Dental Benefit Providers, Inc. to market managed dental products
in New York and Connecticut.  These managed dental products offer different
levels of dental benefits through a selected panel of dentists at a cost that is
below average indemnity plan prices.  These products are designed to increase
the Company's managed care product market penetration and to promote retention
of its enrollee base.  The Company also offers prescription drug riders to its
HMO and POS plans.  The prescription drug riders are offered through PCS, Inc.,
an unaffiliated company that has established contracts with most of the local
pharmacies in the Company's service area.  The prescription drug rider pays the
cost of all covered prescriptions, less, in some instances, a deductible or
copayment. The Company also offers a Connecticut small employer plan to groups
of fewer than 50 employees.  The Company also offers an individual HMO and an
individual POS plan throughout its New York State service area. The Company's
insurance brokerage subsidiary, 

                                       5
<PAGE>
 
PHIS, markets various insurance products of unaffiliated companies such as
dental and life insurance, short-term disability and stop-loss coverage
available from other insurers. PHIS's insurance activities are solely as an
agent and represented less than 0.1% of the Company's total revenues in 1996 .
The Company contracts with Davis Vision of Plainview, New York for provision of
certain routine and non-routine vision services to both commercial and
government product members.


OTHER INVESTMENTS

          In 1995, the Company invested $2.3 million in MasterCare Companies,
Inc. ("MasterCare"), a company offering workers compensation managed care
services in New Jersey and Connecticut. See "Business - Arrangement with
MasterCare."


PROVIDER ARRANGEMENTS

PHYSICIANS AND OTHER HEALTH CARE PROVIDERS

          The Company contracts with physician groups, such as IPAs, PHOs, and
multi-specialty groups (collectively, "Physician Groups"), individual physicians
and other health care providers for a defined range of health services,
including primary and specialty care. As of January 1, 1997, the Company had
agreements with 23,298 providers and 183 hospitals in its tri-state service
area. The Company's contracts with providers include discounted fee for service
arrangements as well as capitated group arrangements in which the contracting
Physician Group assumes a significant amount of the risk of overutilization. The
Company currently has contracts with four IPAs, three PHOs and one large
physician group ("Group") that provide for most of its physician services in its
Connecticut service area. In New York and New Jersey, the Company generally
contracts directly with physicians and other health care providers. Under the
typical Physician Group arrangements, the Physician Group receives a fixed
monthly capitation payment for each member selecting a primary care physician
from that Physician Group. Capitation payments may be for all members selecting
a primary care physician in the Physician Group or only as to members in certain
commercial HMO and POS plans, depending upon the negotiated arrangement with the
Physician Group. Capitation rates and any increases thereto are negotiated for
the term of the contract. The capitation payment is designed to cover not only
the professional medical services (including ancillary tests and services)
rendered by the physicians and other providers associated with that Physician
Group but also includes payments for certain other services rendered to the
enrollee by providers who are not members of the Physician Group. Services
covered by the capitation payment include, among other things, virtually all
physician claims (whether inpatient or outpatient, including authorized out-of-
plan care) and care rendered by other professionals such as physical therapists
and psychologists. In certain of the contracts, the Physician Groups also are at
risk for hospital, pharmacy and other facility expenses. The Company does not
capitate physicians directly.

          Three of the Company's four Connecticut IPA contracts expire on
December 31, 1997; the Company has reached an agreement in principle with the
fourth IPA to extend its present arrangements through December 31, 1997 on
slightly different terms. In the event that the Company was unable or chose not
to renew any Physician Group contract, it would seek alternative arrangements to
ensure the continuation of health care services to its enrollees. However, if
the Company failed to renew any Physician Group contract covering a significant
number of its enrollees and the Company was unable to obtain satisfactory
alternative arrangements, there could be a significant disruption in the
Company's business.

          Each Physician Group reimburses its member physicians and other
providers out of the capitation payment paid to it by the Company according to a
maximum fee-for-service schedule for claims submitted by those physicians and
providers affiliated with the Physician Group.  A portion of each physician's
and provider's payment is withheld and is 

                   


                                       6
<PAGE>
 
contributed to the Physician Group's risk pool to cover those expenses that
exceed the Physician Group's budget for health care expenses. The withheld
portion is returned to providers if the Physician Group operates within its
prescribed budget for services. Because in most instances the capitation
payments received by the Physician Group are fixed amounts unrelated to the
services provided, the provision of excessive services would obligate the
Physician Group to pay more to its physicians than the Physician Group receives
from the Company. The principal exception is the Greater Bridgeport IPA, where
overruns are shared equally between the Company and IPA. The Company's
capitation system is designed to place upon the Physician Group and its member
physicians the responsibility for managing the use of hospital and other medical
services. In the event that the Physician Group is required to pay more to its
physicians than it receives from the Company, the Physician Group must continue
to cover ongoing expenses and will be required to take corrective action to
restore its financial position. Corrective action may include, among other
things, lowering its fee-for-service schedule or increasing its withhold
percentage. The Company believes that the member physicians of its Physician
Groups have an interest in supporting the financial condition of their Physician
Group through temporary reductions in fee schedules and increases in withhold.
In 1996, each Physician Group received a return of all or a portion of its
withhold account. Physician Groups may incur an operating loss which would
result in the Physician Group having a retained earnings deficit. If such
deficit were not eliminated through corrective action, the Company might find it
necessary to advance funds to cover such deficit, although it would not be
obligated to do so. Certain of the Company's IPA stockholders, through their
ownership of Company stock or through members who serve on the Company's Board
of Directors, may seek to have the Company fund such deficits in the future and
failure by the IPAs to eliminate such future deficits, if any, could result in
unrecovered cash advances. Any such funding is subject to approval by the
Board's Audit Committee, a majority of which is composed of independent
directors. If any Physician Group with which the Company contracts for services
became insolvent, such insolvency could have a material adverse effect on the
business of the Company.

         The capitation payments to Physician Groups other than the PHOs
typically do not cover hospital and other facility expenses, although the
Physician Groups are partially at risk for non-Medicare and non-Medicaid
hospital utilization. The Company establishes an annual per member, per month
target for hospital expenses. The amount varies by benefit plan and Physician
Group, and encompasses both inpatient and outpatient costs. If total hospital
expenses generated by the Physician Group exceed the applicable hospital expense
target, the Company withholds from amounts owed by it to the Physician Group all
or a portion of the excess over budget, in most cases one-half of the excess
over budget. If actual costs are less than budgeted targets, the Physician Group
receives from the Company an incentive credit typically equal to forty to fifty
percent of the amount by which actual costs are less than budgeted targets.

          In its New York and New Jersey expansion areas and in areas in
Connecticut not served through Physician Group contracts, the Company contracts
for services principally through direct contracts with individual physicians and
other health care providers. In addition, the Company contracts with two IPAs in
the northern counties of its New York service area. The Company withholds a
percentage of reimbursement for services rendered pursuant to its direct
physician contracts against budgeted amounts to manage excessive utilization.

          The Company provides services to enrollees in PHS/SmartChoice pursuant
to a combination of direct physician agreements, and, in New York, risk sharing
agreements with the aforementioned IPAs. In Connecticut, the Company has
contracted with and is in negotiations with PHOs and other risk entities for its
Medicare risk product to shift the risk of all medical costs to the risk
entity in return for a fixed percentage of the Medicare premium received by the
Company. The Company's agreements in connection with its Medicare risk products
are subject to compliance with new risk sharing regulations adopted by HCFA,
which require disclosure and reinsurance for specified levels of risk sharing,
and proposed state regulations that could affect physician risk sharing.

HOSPITALS

          The Company maintains contracts with 30 acute care hospitals in its
Connecticut service area. In New York, the Company contracts with 83 hospitals
in its service area. The Company has direct and indirect (through MasterCare)
arrangements with 70 hospitals in New Jersey. The Company generally negotiates
contracts with hospitals that include compensation on a per diem basis (at a
daily rate, without regard to the scope of services actually provided). Other
compensation arrangements with hospitals include charged-based discounts
(negotiated discounts from the hospital's billed charges) and all inclusive case
rates. In the case of non-participating hospitals, the Company pays either
hospital billed charges or negotiated discounted charges. Additionally, some
hospital contracts include per case, all-inclusive, payment arrangements for
select procedures such as maternity care.

OTHER HEALTH CARE PROVIDERS

          PHS maintains contracts with outside vendors to provide certain
ancillary services. Laboratory services are provided in Connecticut through an
exclusive arrangement with Diagnostic Medical Laboratory, Inc. Laboratory
services in New York and New Jersey are provided through arrangements with 
Quest Diagnostics. Both are capitated arrangements that are effective through
December 31, 1999 and December 31, 1997, respectively. Mental health, substance
abuse and detoxification services are provided in New York City and Long Island
through a capitated arrangement with CMG Health, Inc. ("CMG"). This agreement is
now in a renewal period and may be terminated by either party with at least 120
days notice. CMG also provides these services for the Company's Medicaid members
in Connecticut under a fully capitated arrangement, which began on August 1,
1995 for a period of 27 months and is automatically renewable thereafter for one
year periods unless terminated by either party on 120 days notice. In
Westchester, Dutchess, Orange, Putnam, and Rockland Counties, New York, CMG
provides case management services only. This agreement is in a renewal period
and may be terminated by either party on at least 120 days notice.


MEDICAL COST CONTROLS

          Control of health care expenses is critical to the profitability of a
managed care company. Expansion into new areas, introduction of new products,
changes in health care practices, medical cost inflation, new technologies,
government regulation, major epidemics, natural disasters and numerous other
factors affecting the delivery and costs of health care may adversely affect the
Company's operating results and financial condition. See "Management's
Discussion and Analysis of Financial Condition and Results of Operations -
Cautionary Statement."

          PHYSICIAN COSTS. The Company has developed several integrated
mechanisms and procedures for the control of health care costs. The Company's
health care programs are designed around primary care physicians who assume
overall responsibility for the care of enrollees and determine or recommend the
nature and extent of services provided to enrollees. In the case of enrollees
enrolled in Passport products, primary care physicians are also responsible for
making referrals to contracted specialist physicians and hospitals. Although the
primary care physician's prior approval for most specialist services is not
required in the Company's Charter products, it is recommended. Prior approval is
required in the Company's Charter products for the enrollee's use of certain
services such as home health care, hospice care, cardiac rehabilitation, private
duty nurses, skilled nursing care, drug and alcohol rehabilitation and, except
for enrollees in a POS plan, elective services rendered out-of-network. In
addition to the prior approval process for certain services, the Company
monitors services rendered to enrollees and provides utilization review
information to its Physician Groups. In cases of possible excessive utilization,
the Company counsels the enrollee with respect to the possible duplication of
services or medications.

          With respect to physicians who contract with PHS through Physician
Groups, costs are also controlled through contracts that provide for payment to
the Physician Group on a capitation basis. The capitation method of payment,
together with the withhold provisions in its contracts, transfers much of the
Company's risk of excessive physician utilization to the Physician Group.
Physicians who contract with PHS directly are not capitated, although withholds
apply in order to mitigate the risk to PHS of excessive utilization.


                                      8
<PAGE>
 
          The Company also endeavors to monitor the practice patterns of all
participating physicians and providers in order to identify inappropriate or
excessive utilization. Each physician's utilization pattern is reviewed against
other physicians within the relevant specialty area in the physician's Physician
Group or relevant geographic area to determine whether average costs per patient
are consistent with utilization generally. In the event there are insufficient
aggregate data in a particular area, the Company's Medical Directors review
utilization data on a specific case basis. If inappropriate utilization is
determined, PHS will typically institute corrective measures including, if
necessary, financial sanctions or, in rare instances, termination of the
physician's membership as a participating physician.

          The Company has developed a measurement tool called the "practice
profile" to evaluate and promote the quality of care being provided to the
Company's members.  The practice profile compares providers to their peers in
relation to specific quality indicators that measure quality across a broad
spectrum of areas.  The practice profile also provides feedback to providers to
assist them in assessing and enhancing their performance.

          HOSPITAL COSTS; UTILIZATION REVIEW. The control of the use of hospital
and other medical services by a member is primarily the responsibility of the
member's primary care physician. The Company requires preadmission notification
of non-emergency hospital admissions and stays, pre-certification of selected
inpatient and outpatient procedures, and retrospective review of ambulatory
health services. The Company also maintains nurse coordinators who are assigned
to certain participating hospitals to conduct concurrent reviews of hospital
admissions. In the event that the nurse coordinator believes that utilization is
inappropriate, the nurse coordinator first addresses his/her concerns with the
attending physician, then consults with a physician advisor, who reviews
admission information and patient records. Physician advisors as well as PHS
Medical Directors are available to assist the attending physician in determining
whether it is appropriate for a patient to remain hospitalized. The physician
advisor, Medical Director and/or nurse coordinator works with the responsible
physician to arrange alternative health care where appropriate, thereby reducing
the length of hospital stays. The Company performs telephonic reviews at certain
hospitals where it is not practical to perform on-site concurrent reviews.

          The Company has implemented special review procedures for
pharmaceutical usage and the treatment of mental health and substance abuse
conditions. In addition to the foregoing controls, the Company has adopted
certain policies relating to the timing of admissions and the use of ambulatory
facilities for certain surgical procedures, among other services, in order to
reduce costs associated with hospital utilization.

          For catastrophic cases, the Company uses case management techniques to
work with the attending physician, facility, patient and his/her family, to
provide care in a cost-efficient manner consistent with the medical needs of the
patient.

          The Company has a pre-certification program for selected elective
inpatient and outpatient procedures to determine the medical necessity of those
services.  The pre-certification program requires the physicians performing the
designated procedures to obtain advance authorization, and permits appeal if the
procedure is initially denied. Procedures that are denied through this program
are ineligible for coverage by the Company.  As a pre-certification tool, the
Company utilizes the Value Health Sciences Medical Review System.  Since
implementation of this program in March 1993, the program has achieved an
overall 21% decrease in the utilization of procedures subject to the program.

          Hospital inpatient costs are also controlled through several
contractual mechanisms. The Company's contracts with Physician Groups contain
risk sharing mechanisms designed to provide incentives to control utilization of
hospital services and its contracts with PHOs include both
professional/physician and hospital/facility services within the capitation
payment to the PHO. In addition, the Company maintains insurance coverage that
reimburses the Company for hospital expenses incurred above certain levels,
limiting the risk to the Company of an individual enrollee's inpatient hospital
expense exceeding specified amounts. See "Business - Stop Loss and Other
Insurance."

MANAGEMENT INFORMATION SYSTEMS

          The Company believes that timely and relevant information is critical
to the success of its managed health care business.  The Company utilizes its
management information systems to process claims on an accurate and timely
basis; to analyze health care utilization; to support provider, member and
employer requirements; and to control administrative costs.  The Company's
claims operation is supported by staff and manager training, adherence to
performance standards (for both productivity and accuracy), auditing of claims
for claims processing accuracy, and adequate staffing and system programming to
ensure adherence to all benefit provisions of the Company's provider policies.
Currently, approximately 30% of physician/provider (non-facility) claims and
approximately 20%  of institutional claims are received electronically from the
Company's providers.  The Company intends to increase the amount of claims that
it processes electronically.  The Company's imaging system enables further
automation of the claims process.  The Company believes that its electronic
claims capabilities combined with the Company's imaging system have enabled the
Company to establish highly efficient claims processing and information
retrieval systems.  The Company has in place a disaster recovery plan that
provides for a back-up of its management information system in case of an
emergency.

          The Company is in the process of completing a significant upgrade of
its management information systems. The new systems are expected to begin to
come on line during the second quarter of 1997. At December 31, 1996, the costs
associated with this project included capital expenditures of approximately
$18.6 million, including enhancements beyond the original scope of the project.
The capital expenditures are expected to be amortized over five years commencing
with fiscal year 1997. When completed, the conversion to the new system is
expected to yield significant gains in productivity, accuracy and speed as well
as permit more significant information evaluation. See "Management's Discussion
and Analysis of Financial Condition and Results of Operations - Cautionary
Statement. "


QUALITY ASSURANCE AND CUSTOMER SERVICE

          Prior to a physician's acceptance for participation in the Company's
network of providers, the Company reviews the physician's credentials and
background. Each physician must be board certified in his/her specialty, or
become board certified within five years of becoming credentialled. PHS has a
rigorous credentialling process that consists of primary verification of all
credentials; query of the National Practitioner Data Base, state medical boards
and admitting hospitals for malpractice history, disciplinary actions and/or
restrictions of hospital privileges; and on-site office evaluations including a
review of medical records to determine compliance with PHS's standards. The
Company biennially recredentials all its providers. Recredentialing includes
repeating the initial credentialling process as well as a reviewing the
provider's practice history with PHS. After acceptance, the Company monitors
various aspects of the physician's performance on an ongoing basis, including
the quality and appropriateness of care delivered. The Company evaluates the
quality and appropriateness of medical care provided to its enrollees by
performing medical care evaluation and member satisfaction studies, by reviewing
utilization of certain services and by responding to enrollee and physician
questions and concerns.

          In August 1995, the Company was awarded full three-year accreditation
in its then current service areas from the National Committee for Quality
Assurance ("NCQA"), an independent organization that reviews HMOs for compliance
with their quality standards.  This accreditation is effective from May, 1994
through May, 1997.  In connection with the re-accreditation process, the NCQA
staff made an on-site visit in late March, 1997.

          The Company has also established a formal system for documenting and
responding to customer grievances. The Company had no grievances upheld against
it during 1993, 1994 and 1995 by the New York Insurance Department. The Company
also had no complaints upheld against it during 1994 and only one complaint
upheld against it in 1995 by the Connecticut Department of Insurance. The
Company anticipates similarly good results for 1996. The Company believes that
it has established a reputation for high standards of service.

                                       10

ENROLLMENT, EMPLOYER GROUPS AND MARKETING

          As of December 31, 1996, the Company provided managed health care
coverage to 400,021 enrollees. The Company offers its products to small groups,
generally on a total replacement basis, and to medium and large groups on both a
total replacement as well as alternative bases. The small group market segment
is currently marketed throughout the Company's tri-state service area through
its alliance with The Guardian and, in Connecticut, also through CBIA. In the
large group market, the Company sells both its proprietary HMO and POS products,
as well as ASO products. The Company's enrollee base is diverse and includes
federal and state employees and employees of banks, hospitals and major
industries. The Company's five largest fully insured employer groups represent
approximately 17% of its 332,363 fully insured enrollees and 14% of its total
enrollees. The New York State Nurses Association Benefits Fund, which
constitutes the largest fully insured employer group, represents 7.2% of the
Company's total enrollees and 8.6% of its fully insured enrollees.

          Employer groups of 50 or less are subject to community rating
restrictions throughout the Company's service area.  In these areas, the Company
uses underwriting guidelines and rating practices that comply with state
mandated community rating regulations.  In Connecticut and New Jersey, groups of
over 50 members are not subject to community rating regulation.  For these
groups, the Company employs rating techniques and underwriting guidelines
designed to price its products according to expected health care utilization
based on group experience.

          In New York, all groups written on the Company's HMO license are
subject to community rating regulations.  The Company uses underwriting
guidelines and rating practices that comply with New York mandated community
rating regulations.  See "Business - Competition."  The Company expects to begin
marketing an experience rated POS product in the over 50 employee group market
in mid-1997. In addition, the Company currently experience rates certain of its
Healthcare Solutions products offered in the over 50 employee group market in
New York.

          Subject to underwriting guidelines, the Company solicits new employer
groups for its proprietary products through its marketing staff and employee
benefits consultants. Most larger employer groups are represented by brokers and
consultants, who are typically paid by the employers, and work with the employer
to recommend or design employee benefit packages. The Company utilizes an
internal staff of sales and account service representatives and managers to
market its benefit plans to employers.  Healthcare Solutions products are sold 
through the Company's and The Guardian's respective marketing staffs, as well as
through independent brokers.

          Marketing the Company's benefit plans in the alternative carrier
market is typically a two-step process in which presentations are first made to
employers and, after the employer selects the Company as one of its health care
providers, to its employees.  In the total replacement market, sales are made
solely at the employer levels and employees then can select from a number of PHS
products, or in the case of Healthcare Solutions, PHS or The Guardian products.

          The marketing process is continuous because contracts with employers
are typically renewed annually, employees are permitted to change plans annually
and employer groups experience regular employee turnover.


JOINT MARKETING ARRANGEMENT WITH THE GUARDIAN

          The Company has a joint marketing arrangement with The Guardian
throughout its tri-state service area.  The products that are subject to the
joint marketing arrangement are distributed through the brokerage community in
an integrated marketing effort.  The products are generally sold on a total
replacement basis, which eliminates the need for marketing to employees once the
products are sold to the employer group.  Products are marketed under the trade
name "Healthcare  Solutions" and employees are able to choose among PHS's
traditional HMO and POS products as well as, in certain instances, The
Guardian's indemnity products.  The Company and The Guardian target groups that
are currently enrolled in The Guardian's indemnity products.  Because of the
higher premiums associated with indemnity insurance generally, such groups are
often receptive to conversion to the Healthcare Solutions products.  The Company
and The Guardian also market to new groups.

                                       11
<PAGE>
 
          The joint marketing arrangements with The Guardian are for an
unlimited term but can be terminated by either party either with or without
cause, subject to potentially significant payments upon termination in the event
of a termination without cause, by the party electing to terminate, and in the
event of certain for cause terminations, by the party breaching the agreement.
The agreements can also be terminated by either party with respect to new
business following a change in control of the other party, in which event the
parties would continue to share profits and losses on business in effect on the
date of the change in control for a period of up to ten years. For a description
of the Company's financial arrangements with The Guardian in connection with the
Healthcare Solutions business, see "Management's Discussion and Analysis of
Financial Condition and Results of Operations" and Note 10 to the Consolidated 
Financial Statements.

          As of December 31, 1996, there were 112,566  members enrolled in
Healthcare Solutions products (43,773 in Connecticut, 53,153 in New York and
15,640 in New Jersey).


STOP-LOSS AND OTHER INSURANCE

          The Company maintains reinsurance coverage for its existing business
to limit the risk of an individual member's inpatient hospital expense exceeding
specified amounts. The Company believes that its reinsurance coverage
substantially limits its risk of incurring catastrophic costs at a reasonable
premium cost. Beginning January 1, 1996 and continuing throughout 1997, the
reinsurance arrangement for the Company's HMO products throughout its entire
service area covers 80% of the next $400,000 of any member's inpatient hospital
expense and emergency out-of-area services (up to a stated daily maximum) in
excess of a $600,000 deductible. The reinsurance agreement provides a limit of
$1,000,000 per member, per contract period (12 months) and $2,000,000 per
member, per lifetime. The Company also maintains general liability, property,
fidelity and contingent malpractice insurance coverage in amounts it believes to
be adequate. Such insurance may become increasingly important if plaintiffs
prove successful in recent efforts to expand the liability of a managed health
care company for the negligence of providers with whom the Company directly or
indirectly contracts. The Company also requires contracting Physician Groups and
hospitals to maintain malpractice insurance coverage.


ARRANGEMENT WITH MASTERCARE

          The Company has entered into a marketing relationship with MasterCare
and its affiliates. In addition, the parties have network access agreements with
each other stemming from their respective expansion activities. In connection
with the formation of PHS/NJ, the Company used the MasterCare network of
providers to help it develop a network in New Jersey. As consideration, the
Company issued a 20% interest in PHS/NJ to MasterCare. In addition, at December
31, 1996 PHS owned an interst in MasterCare Companies, Inc. and its subsidiary,
MasterCare of Connecticut, formerly Total Employee Care, a workers compensation
company formerly wholly-owned by the Company. See Note 11 to the Condolidated
Financial Statements.


GOVERNMENT REGULATION

FEDERAL REGULATION

          The Company is subject to the Health Maintenance Organization Act of
1973, as amended, and the rules and regulations promulgated thereunder ("HMO
Act"), which prescribe the manner in which an HMO must be organized and operated
in order to meet and maintain federal qualification and to be eligible to enter
into Medicare contracts with the federal government.  PHS/CT and PHS/NY are
federally qualified under the HMO Act.  In order to maintain this status the
Company must file periodic reports with, and is subject to periodic review by,
the Department of Health and Human Services through HCFA and the Office of
Prepaid Health Care.  In addition, HCFA has the 

                                       12
<PAGE>
 
right to audit the Company to determine compliance with HCFA's regulations and
to monitor the quality of care rendered to PHS/CT's and PHS/NY's Medicare
enrollees. Reimbursements payable to PHS/CT and PHS/NY under the Medicare risk
contracts are subject to periodic unilateral revision by the federal government.
Future levels of such payments may be affected by federal government efforts to
contain health care costs and cannot be predicted with certainty. Each of the
Company's Medicare contracts are renewable on an annual basis. Health plans
which offer a Medicare risk product must also comply with requirements
established by peer review organizations, which are organizations which contract
with HCFA to monitor the quality of health care received by Medicare
beneficiaries. These requirements relate to quality assurance and utilization
review procedures. Recent requirements of HCFA impose requirements relating to
physician incentive plans, which place physicians participating in Medicaid and
Medicare HMO plans at substantial financial risk.  Enrollment under
the Medicare risk program cannot exceed 50% of a health plan's total enrollment.
Termination of the Company's Medicare program could have a material adverse 
effect on its business.

          As a result of its Medicaid contract,  PHS/CT is subject to both
federal and state regulation regarding services provided to Medicaid enrollees,
payment for those services and other aspects of the Medicaid program.  Medicaid
regulations require that enrollment of Medicaid and other federal government
program beneficiaries cannot exceed 25% of a health plan's total enrollment.

          The Company is also required by federal and state regulatory agencies
to maintain restricted cash reserves and/or a minimum net worth.  To remain
licensed, it may be necessary for the Company to make changes from time to time
in its services, procedures, structure and marketing methods.  Such changes may
be required as a result of amendment to, or other significant modification of,
federal and state laws and regulations controlling the Company's operations.
Any changes in federal or state government regulation could affect the Company's
operations, profitability and business prospects.


STATE REGULATION

          The Company's HMO and insurance subsidiaries are subject to
substantial state government regulation. PHS/CT is licensed by the Insurance
Commissioner of Connecticut to be a health maintenance organization and is
subject to regulation by the Connecticut Department of Insurance.  PHS/NY is
also licensed as a health maintenance organization by the Commissioner of Health
of the State of New York and is subject to regulation by the Department of
Health of the State of New York and the Department of Insurance of the State of
New York. PHS/NJ is licensed as a health maintenance organization by the
Commissioner of Health and Senior Services and Commissioner of Banking and
Insurance of the State of New Jersey and is subject to regulation by the
Department of Health and Senior Services of the State of New Jersey and the
Department of Banking and Insurance of the State of New Jersey. State regulatory
authorities exercise oversight regarding the Company's provider networks,
medical care delivery and quality assurance programs, contract forms and their
provisions, and financial condition, including reserve and cash flow
requirements. Applicable state law requires periodic financial reports, imposes
minimum standards for investments, capital, deposits and reserves, and regulates
marketing, rates, medical benefits, payment of dividends and affiliate
transactions. In addition, the premiums charged by the Company are subject to
review and changes in rates must be approved in advance by state regulatory
authorities. The Company's HMOs are also subject to periodic examination by the
relevant state regulatory authorities.

          Insurance/CT is an accident and health company licensed by the
Connecticut Department of Insurance, Insurance/NY is a property and casualty
company licensed by the New York Department of Insurance and Bermuda is an
insurance company licensed as a reinsurer in Bermuda. Applicable laws contain
requirements relating to Insurance/CT's, Insurance/NY's and Bermuda's financial
condition, reserve requirements, premium rates and contracts and require
periodic filings and examinations.

          Applicable Connecticut, New York and New Jersey statutes and
regulations require the prior approval of the Connecticut Commissioner of
Insurance, New York Commissioner of Health and New Jersey Commissioner of
Health, respectively, for any acquisition of control of the Company or its
subsidiaries.  For purposes of these statutes and regulations, "control" means
the direct or indirect possession of the power to direct or cause the direction
of the 

                                       13
<PAGE>
 
management and policies of an entity. Control is presumed to exist when a
person, group of persons or entity acquires the power to vote 10% or more of the
voting securities of another entity.

          New York law requires health insurers to accept all individuals and
small groups (between three and fifty employees or group members) without regard
to their age, sex, occupation or medical condition at a "community rated"
premium based on the experience of the entire pool of risks covered by the
insurer. The New York community rating law establishes a pooling mechanism
providing for payments to insurers writing such policies for a disproportionate
share of individuals with certain demographic characteristics and catastrophic
medical expenses. Depending on the age and sex characteristics of an insurer's
members and the incidence of certain high-cost medical conditions among members,
an insurer will either make payments to or receive payments from the state
pooled fund. To date, the Company has incurred expenses related to this fund
amounting to $1,152,000 in 1994, $1,483,000 in 1995 and $3,180,000 in 1996. The
New York community rating law also provides, among other things, for portability
of health insurance, thereby facilitating continued coverage for those wishing
to seek new employment or insurers, and allows members of a small group to
continue their coverage after their membership is terminated. New York law
requires all HMOs to offer an individual HMO plan and an individual POS plan.
The benefits available under these plans are mandated by law and do not differ
between health plans.

          Connecticut law also regulates health insurance for employer groups of
fifty and fewer employees.  The Connecticut small employer insurance law
includes guaranteed issue, pre-existing condition restrictions and guaranteed
renewability provisions.  Connecticut applies adjusted community rating
restrictions to all small employer medical plans.  Under adjusted community
rating, the only factors that may be used are age, gender, geographic area,
industry, group size and family composition.  Such factors are further limited
by applicable Connecticut law.

          New Jersey regulates health insurance for employer groups of two to
forty-nine employees through the New Jersey Small Employer Health Benefits
Program.  The law sets out six standard plans, only one of which is an HMO plan
(the others are all indemnity plans).  The law also mandates the benefits to be
offered under such plans and sets out the participation and contribution
requirements, applies a preexisting condition restriction, guaranteed
renewability and rating restrictions.

          The Company's HMO subsidiaries are subject to statutory regulations
that restrict the payment of dividends. Connecticut law imposes a 1.75% premium
tax on the Company's fully insured business written in Connecticut. All HMOs in
Connecticut are now assessed for the costs of the HRA (Health Reinsurance
Association), which offers individual coverage to any person residing in
Connecticut and special health care plans to low income groups of ten or less.
The assessments are used to cover the losses incurred by the program. In
addition, all Connecticut HMOs are now assessed a portion of the cost of funding
the Connecticut Department of Insurance, which until recently had been funded
entirely by assessments only on insurers operating in the state.

          If the Company acquires or establishes HMOs in states where it does
not presently operate, it will have to comply with the applicable state statutes
which vary from state to state.

RECENT REGULATORY DEVELOPMENTS AND INITIATIVES

Federal
          The recently enacted Federal Health Insurance Portability and
Accountability Act of 1996 (i) insures portability of health insurance to
individuals changing jobs or moving to individual coverage by limiting
application of pre-exiting condition exclusions, (ii) guarantees availability of
health insurance to employees in the small group market and (iii) prevents
exclusion of individuals from coverage under group plans based on health status.
The Act also permits offering Medical Savings Account plans on a pilot basis and
includes programs targeting fraud and abuse.  The provisions are effective
beginning July 1, 1997.  The Company is currently subject to similar state law
provisions in New York limiting pre-existing conditions for new group and
individual enrollees who had continuous prior coverage and requiring issuance of
group coverage to small group employers.  Recently enacted federal legislation
mandates coverage for minimum hospital stays after childbirth (consistent with
many new state law requirements) and parity between any lifetime limits imposed
on mental health benefits and those for other medical 

                                       14
<PAGE>
 
benefits. In addition, HCFA adopted rules in 1996 imposing reinsurance,
disclosure and other reporting requirements relating to physician incentive
plans which place physicians participating in Medicare and Medicaid HMO plans at
substantial financial risk.

          Congress is also considering significant changes to both Medicare and
Medicaid programs, including changes that would significantly reduce
reimbursement to HMOs. See "Management's Discussion and Analysis of Financial
Condition and Results of Operations - Cautionary Statement". In addition,
proposed Medicare reform bills contain provisions that would facilitate entry of
competing HMOs in the Company's service area by repealing the rule that Medicare
risk contractors have one commercial enrollee for each Medicare or other
government program enrollee and creating permissive licensure for HMOs sponsored
by provider networks. In Connecticut, the Department of Social Services is
expected to request HMOs participating in its Medicaid program to resubmit bids
in 1997. It is expected that Connecticut will mandate additional reporting
requirements and other changes that will reduce the number of companies willing
to participate.

State
          There is a national trend among state governments to enact legislation
which increases regulation of HMOs and managed care companies and to mandate
certain policies and procedures.  Each state that the Company does business in
is considering or has implemented wide-ranging "Patient Protection" and
"Consumer Disclosure" bills and regulations.

          The New York State legislature enacted the Health Care Reform Act of
1996 ("HCRA"), effective January 1, 1997, that eliminated regulation of hospital
rates and adopted surcharges and covered lives assessments to fund various
public programs. This deregulation allows all private health care payors to
negotiate payment rates for inpatient hospital services. Previously, only HMOs
could negotiate rates for these services. As a result of the enactment of HCRA,
non-HMOs who compete with the Company may be able to negotiate better rates with
hospitals in New York because of the volume of patients they represent, which
would have an adverse effect on the Company's ability to compete effectively in
New York. Also, effective January 1, 1997, the Company is required to make
payments to state funding pools to finance hospital bad debt and charity care,
graduate medical education, and other state programs under HCRA. Previously,
hospital bad debt and charity care and graduate medical education were financed
by surcharges on payments to hospitals for inpatient services. The Company has
renegotiated many of its hospital contracts in New York to reflect the
surcharges. These adjustments are generally effective as of January 1, 1997, but
they are not expected to result in savings equal to the cost of the surcharges.
The New York legislature also recently passed legislation related to operation
of managed care plans, which contains provisions relating to, among other
things, utilization review, consumer disclosure and the right of a physician to
a hearing on termination from a health plan network.

          In addition, the New Jersey Department of Health and Senior Services
recently issued a comprehensive revision to its existing HMO regulations, which
encompasses many of the same features as the aforementioned New York law, but
also includes a non-binding external appeals process. Connecticut is considering
increased regulation which, like New York and New Jersey, includes extensive new
reporting and data collection requirements. These regulatory developments are
likely to increase the Company's medical and administrative costs.

COMPETITION

          The health care industry in the Company's market area is highly
competitive. The Company has numerous competitors, including for-profit and not-
for-profit HMOs , preferred provider organizations ("PPOs") and indemnity
insurance carriers, and certain of the Company's competitors have substantially
greater enrollment and financial
                                       15

resources than the Company. The Company's major competitors include independent
HMOs, such as Oxford Health Plans, Inc., and United Health Care, which have
significant enrollment in the New York metropolitan area, and HMOs and managed
care plans sponsored by large health insurance companies, such as Aetna/U.S.
Healthcare, Inc., Blue Cross/Blue Shield, The New York Life Insurance Company
and CIGNA. Additional competitors may enter the Company's market in the future.
In addition, the managed care industry has experienced significant consolidation
recently, and such consolidation is expected to continue, possibly resulting in
fewer but larger competitors in the Company's service area. The Company competes
on the basis of price, quality and scope of services provided, including the
extent of its provider network. The Company believes the quality of its service
and physicians, as well as its reputation, are important competitive factors.
However, the cost of providing benefits is in many instances the controlling
factor in obtaining and retaining employer groups and certain of PHS's
competitors have set premium rates at levels below PHS's rates for comparable
products. The Company anticipates that premium pricing will continue to be
highly competitive.


TRADEMARKS AND TRADENAMES

          The Company has a number of registered trademarks.  The Company
believes that its trademarks and tradenames are important to its marketing
efforts.  Any challenge to the use of a material tradename, trademark or service
mark could have an adverse effect upon the Company's business.


EMPLOYEES

          As of December 31, 1996, the Company had 971 full-time employees.  The
Company is not a party to any collective bargaining agreement and has not
experienced any work stoppage since its organization.  The Company believes its
relations with its employees to be good.


ITEM 2.  PROPERTIES

          The Company's corporate headquarters offices were relocated to
Shelton, Connecticut in early 1997 and comprise 327,195 square feet, located in
three adjacent building, which the Company purchased in June, 1996 for $16.6
million. The Company presently occupies approximately 65% of the available space
in this facility. The Company expects that the remainder of the available space
will require renovation before it can be occupied by the Company's employees.
The Company continues to own and occupy its former headquarters in Trumbull,
Connecticut which comprises 74,350 square feet. PHS/CT leases properties at
three locations, for an aggregate of 97,488 square feet. PHS/NY leases 11,752
square feet of property in White Plains, New York, 18,415 square feet in New
York City and 3,415 square feet in Lake Success, New York. PHS/NJ leases 12,895
square feet of space in Paramus, New Jersey.


ITEM 3.  LEGAL PROCEEDINGS

          The Company is involved in litigation arising in the ordinary course
of its business, a significant portion of which involves claims for coverage or
payment of medical services rendered to enrollees. In the opinion of the
Company's management, based upon discussions with legal counsel, existing
litigation will not have a material adverse effect on the Company's financial
position.


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

         No matters were submitted to a vote of security holders during the
fourth quarter.

    The Company's subsidiaries, PHS/CT, PHS/NY, PHS/NJ and Bermuda, have entered
into several marketing and reinsurance agreements with The Guardian. Under these
agreements, jointly developed managed care and indemnity products are offered to
existing Guardian insureds as well as to new prospects. The Company and The
Guardian have implemented different ways to share profits and losses under these
agreements which vary among the particular states and time periods as described
below.

    In Connecticut, PHS/CT wrote 100% of the managed care business and The
Guardian wrote 100% of the indemnity business. The parties shared profits and
losses through September 30, 1996 pursuant to a "selection adjustment payment"
mechanism. Under this arrangement, each party calculated its quarterly profit or
loss (net premiums earned, minus claims payments, capitation payments and
withholds paid with respect to managed care plans, reserve increases or
decreases, administrative charges, commissions and premium taxes, plus
investment income). The selection adjustment payment, which was designed to
mitigate the effect of potential adverse selection in groups which selected
Healthcare Solutions products and enable the parties to share in any long-term
profits or loses, then provided that if both parties had losses, no adjustment
would be made from one to the other, and each would retain its respective loss.
If both parties had profits, the amounts were combined, and the party with the
greater profit would make a selection adjustment payment to the other, in an
amount equal to half of the profit differential. If only one party had a profit,
the
                                       19
<PAGE>
 
profitable party made a selection adjustment payment equal to that party's
reported profit, thereby partially or fully reimbursing the other party's loss.
If the result was a combined profit, the profitable party would make a selection
adjustment payment equal to the other party's loss, increased by half of the
combined profit. Selection adjustment calculations were done on a cumulative
basis, and accordingly, losses are carried forward to offset against future
profits. Because both PHS and The Guardian incurred losses in Connecticut in
1996, no selection adjustment payment was made, and the Company reported 100% of
the cumulative losses on the managed care products sold under the Healthcare
Solutions product line.

    The parties entered into new agreements with respect to the Connecticut
Healthcare Solutions business that were effective as of October 1, 1996. The
selection adjustment methodology was replaced with a reinsurance agreement
pursuant to which the Company cedes 50% of the risk on the managed care portion
of the Healthcare Solutions products to The Guardian. In connection with the
conversion to reinsurance, the parties agreed that 50% of the cumulative losses
in Connecticut would be offset from amounts otherwise due to The Guardian under
the reinsurance agreement when profits, if any, are generated.

In New York, The Guardian cedes 50% of its risk for the out-of-network portion
of the POS Healthcare Solutions products to Bermuda and the Company cedes 50% of
its risk for HMO products and the in-network portion of the POS Healthcare
Solutions products to The Guardian. In New Jersey, the Company cedes 100% of the
risk of the out-of-network portion of the POS Healthcare Solutions products and
50% of the risk on the other HMO Healthcare Solutions products to The Guardian
and The Guardian retrocedes 50% of the risk for the out-of-network portion of
the POS Healthcare Solutions products back to Bermuda. The reinsurance
agreements were amended in 1996 to reduce the Company's risk for indemnity
Healthcare Solutions products. In New York, the Company was responsible for 10%
of the associated losses on the indemnity business between January 1 and June
30, 1996 and did not share risk with respect to the indemnity portion of the
Healthcare Solutions business after June 30, 1996. In Connecticut, the
agreements were amended effective October 1, 1996 so that the Company will not
share risk with respect to the indemnity business in those states following
September 30, 1996.

As a result of its arrangements with the Guardian, the Company's percentage
growth in its aggregate premium revenue has lagged its percentage growth in
enrollment, since a portion of the Healthcare Solutions revenues and expenses
that were ceded to The Guardian are omitted from the Company's Statement of
Operations. The Company expects that this trend will continue if its Healthcare
Solutions products continue to be successful and the enrollment mix between its
proprietory products and the Healthcare Solutions products shifts to a greater
percentage in Healthcare Solutions. The aggregate revenue is impacted by this
mix due to the fact that for its proprietary products the Company retains 100%
of the revenue and related healthcare expenses while under the Healthcare
Solutions product, 50% of the revenue and related health care expenses are ceded
to The Guardian, therefore impacting the aggregate revenue growth compared to
aggregate membership growth. Per member, per month ("PMPM") amounts are
similarly impacted by this mix due to the fact Healthcare Solutions membership
is reflected at 100% and revenue and related health care expenses are reflected
at 50%.

RESULTS OF OPERATIONS

YEAR ENDED DECEMBER 31, 1996 COMPARED TO YEAR ENDED DECEMBER 31, 1995

    Premium revenue increased 40.4% to $481.5 million in 1996 from $343.0
million in 1995, while enrollment at December 31, 1996 increased 49.8% over 1995
to 400,021. As of December 31, 1996, fully-insured enrollees increased 59.9% to
332,363 members up from 207,856 as of December 31, 1995, while self-funded
enrollees increased 14.2% to 67,658 members as of December 31, 1996, up from
59,260 at December 31, 1995. The aggregate premium revenue increase lagged the
membership growth due primarily to the growth of membership in the Healthcare
Solutions product where 50% of the premium revenue and related healthcare costs
are ceded to The Guardian pursuant to the agreement and a membership shift in
the fully insured product mix to lower benefit, lower PMPM revenue products.
Also, enrollee statistics include 100% of the approximately 112,000 members
enrolled in Healthcare Solution products at December 31, 1996, while premium
revenue includes only the Company's 50% share of the Healthcare Solutions
revenues derived from the New York arrangements which became effective July 1,
1995, the New Jersey arrangements effective January 1, 1996, and the Connecticut
arrangements effective October 1, 1996.


                                       20
<PAGE>
 
    Investment and other income declined 5.6% in 1996 from $7.0 million for the
year ended December 31, 1995 to $6.6 million for the year ended December 31,
1996.  The decline in investment income is due primarily to a decline in
invested assets and lower investment yields due to lower interest rates.

    Health care expenses as a percentage of premium revenue (medical loss ratio)
increased to 89.8% for 1996 from 78.2% for 1995. The increase in the medical
loss ratio resulted from a 7.4% increase in medical costs on a PMPM basis
(primarily hospital and prescription drug costs as discussed below) and a
decline of 6.5% in the PMPM premium revenue.

    Hospital services expenses increased 59.1% to $178.1 million in 1996 from
$111.9 million in 1995. The increase is due primarily to an increase in fully-
insured membership. On a PMPM basis, however, hospital services increased 5.7%
from 1995 to 1996. This increase is attributable primarily to the recent trend
to perform certain lower cost services, which historically had been performed in
an in-patient setting, in an out-patient setting. This results in a higher
average cost for those services which are still performed in an in-patient
setting. Inpatient hospital utilization for fully-insured commercial enrollees
decreased 3.2% to 272 days per thousand members, per year for the year ending
December 31, 1996 from 281 days per thousand members, per year for the same 1995
period. This decrease was primarily due to the continued trend towards less
expensive treatment being provided in the out-patient setting and more effective
medical management techniques.

    Physician and related health care expenses increased 51.6% in 1996 from
1995.  The increase is primarily due to the 59.9% increase in fully insured
membership as well as increases in non-capitated expenses, including costs for
out-of-network physicians' services.

    Other health care expenses increased by $23.7 million from 1995 to 1996 due
primarily to higher prescription drug costs resulting from an increase in the
number of members covered by prescription drug riders.  Additionally, there was
a shift in membership to drug riders which offered greater benefits.  At the
same time, fewer generic drugs were prescribed resulting in increased pharmacy
costs.

    Indemnity costs reflect the medical costs associated with the indemnity
revenue assumed in connection with The Guardian reinsurance arrangement in New
York which began in 1995. The Company's net indemnity costs for 1996 were $7.0
million, up from $2.2 million for 1995. As a result of continuing adverse
experience related to this business, the Company amended the New York
reinsurance agreement to reduce the Company's share of the indemnity business
assumed from 50% to 10%, for the period from January 1, 1996 to June 30, 1996.
The impact of this adjustment reduced the after tax loss associated with the
indemnity business by approximately $900 thousand, which was recorded in the
second quarter of 1996. The amendment also provided that the Company will assume
no further indemnity risk in the New York market for claims incurred after June
30, 1996. As noted above, after September 30, 1996 the Company did not share
risk in connection with the Healthcare Solutions indemnity business in the
Connecticut market. Selling, general and administrative expenses increased 48.2%
to $86.7 million in 1996 from $58.5 million in 1995. The increase was
principally due to additional staffing, outside services and other costs needed
to support geographic expansion, product diversification and enrollment growth.

    The Company's effective tax benefit rate was 46.5% for the year ended
December 31, 1996, as compared to an effective tax provision rate of 34.6% for
the comparable 1995 period.  The 1996 effective tax rate resulted primarily from
the favorable effect of the income from tax exempt securities which increases
the tax benefit when there are losses.

    The Company has undertaken a number of actions intended to restore
profitability in 1997. It increased its premiums an average of 4.4% at the end
of 1996 for groups renewing in 1997 and may make further adjustments subject to
competitive conditions. It has moved to introduce enhanced medical management,
which is intended to result in reduced health care expenses on a PMPM basis in
1997. In addition, its contracts with risk entities shift a greater amount of
the risk of overutilization to the risk entities, which will provide further
protection against rising health care costs. Moreover, the Company has shifted a
portion of the Healthcare Solutions membership to capitation arrangements with
the Physician Groups. Although there can be no assurance that these changes,
among others, will enable the

                                       21
<PAGE>
 
Company to be profitable in 1997, the Company expects to see significant
improvement in its financial results in 1997. See "Management's Discussion and
Analysis of Financial Condition and Results of Operations--Cautionary 
Statement."


YEAR ENDED DECEMBER 31, 1995 COMPARED TO YEAR ENDED DECEMBER 31, 1994

    Premium revenue increased 18.4% to $343.0 million in 1995 from $289.8
million in 1994 while enrollment at December 31, 1995 increased 48.8% over 1994
to 267,116.  As of December 31, 1995, fully-insured enrollees increased 55.5% to
207,856 members from 133,676 as of December 31, 1994, while self-funded
enrollees increased 29.2% to 59,260 members as of December 31, 1995, up from
45,874 as of December 31, 1994.  The premium revenue increase lagged the
membership growth due to more aggressive pricing and a shift in fully insured
product mix to lower revenue yielding products.  Also, enrollee statistics
include 100% of the enrollees in New York, while premium revenue includes only
the Company's 50% share of revenues derived from the New York Guardian
arrangements which become effective July 1, 1995.

    Investment and other income was up 67.5% in 1995 from $4.2 million for the
year ended December 31, 1994 to $7.0 million for the year ended December 31,
1995.  The increase in investment income was due to improved portfolio yields
and a reduction in realized losses.

    Health care expenses as a percentage of premium revenue (medical loss ratio)
decreased to 78.2% for 1995 from 79.0% for 1994.  The decrease in the medical
loss ratio resulted from a 7.0% decline in medical costs on a per member per
month basis which was partially offset by a 6.4% decline in the per member per
month premium revenue.  Total health care expenses increased 17.1% to $263.8
million in 1995 from $225.3 million for 1994.

    Hospital services expenses increased 17.9% to $111.9 million in 1995 from
$94.9 million in 1994.  On a PMPM basis, hospital services declined 6.8% from
1994 to 1995.  The decline was due primarily to a reduction in in-patient
hospital utilization which was partially offset by higher out-patient
utilization.  In-patient hospital utilization for fully-insured enrollees,
excluding Medicare cost contract enrollees, decreased 14.1% to 281 days per
thousand members per year for the year ending December 31, 1995 from 327 days
per thousand members for the same 1994 period.

    Physician and related health care expenses increased 11.6% in 1995 from 1994
despite a 55.5% increase in fully insured enrollees.  As a result, physician
expense declined 11.8% on a per member per month basis for the year ended
December 31, 1995 as compared to the same 1994 period.  The decrease is largely
due to more favorable capitation arrangements with providers and a shift in
membership to lower cost capitated products.

    Other health care expenses increased by $5.8 million from 1994 to 1995 due
primarily to higher prescription drug expense resulting from an increase in
prescription drug benefit coverage and increased utilization.  Additionally, in
1995, other health care expenses includes the Healthcare Solutions profit
sharing expense which resulted from The Guardian reinsurance arrangement in
Connecticut.

    Indemnity costs reflect the medical costs associated with the indemnity
revenue assumed in connection with The Guardian reinsurance arrangement in New
York which began in 1995.

    Selling, general and administrative expenses increased 32.7% to $58.5
million in 1995 from $44.1 million in 1994.  The increase was principally due to
continuing resource commitments to support enrollment growth and the expansion
into the Connecticut, New York and New Jersey tri-state region.  Additionally,
the related administrative infrastructure was also expanded to accommodate the
increased growth.

    The Company's effective tax rate declined to 34.6% for the year ended
December 31, 1995 from 42.5% for the comparable 1994 period. The decline in the
effective tax rate resulted primarily from the shift of much of the Company's
investment portfolio into tax exempt municipal bonds and to a slight decline in
the statutory state income tax rates. Additionally, the effective tax rate for
1995 was favorably affected by the reconciliation of prior provisions.

LIQUIDITY AND CAPITAL RESOURCES

    PHS has historically financed its operations primarily through internally
generated funds. The Company's primary capital requirements are for working
capital, principally to fund geographic and product expansion, and to maintain
necessary regulatory capital. In addition, the Company's HMO subsidiaries,
PHS/CT, PHS/NY and PHS/NJ, and its insurance subsidiaries, are subject to
statutory regulations that restrict the payment of dividends.

    Net cash flows for the year ended December 31, 1996 resulted in an increase
in cash and cash equivalents of $31.7 million. Although operating cash flows
were unfavorably affected by the Company's 1996 loss of $13.0 million, net cash
was provided by operating activities of $24.6 million for the year ended
December 31, 1996. The difference between the net loss and the net cash provided
from operating activities resulted primarily from a $22.3 million increase in
hospital incurred but not reported ("IBNR") claims, which was generated from the
increase in the volume of claims activity due to the rise in membership and
the timing of the related claims payments and from the collection of outstanding
advances to hospitals which totalled $5.5 million. Additionally, the amounts due
to IPAs, physicians and other providers increased $15.3 million in 1996,
reflecting an increase in the amounts payable to non-capitated providers, such
as out of network providers, and the timing of those related payments. These
items were offset in part by the net increase in receivables of approximately
$10.0 million which occurred due to the growth in enrollment from both the
Company's proprietary business and from its arrangements with The Guardian.
Approximately $44.0 million of net cash was provided by the sales and maturities
of marketable securities, of which $34.6 million was used to fund the
enhancement of the Company's computer infrastructure and to purchase the
Company's new corporate headquarters .

   PHS's net cash used in operations amounted to $9.5 million in 1995. Since The
Guardian holds the funds generated by Healthcare Solutions, on which the Company
earns interest, and since the funds were not released by year end, operating
cash flows in 1995 were unfavorably affected by the arrangements with The
Guardian. In addition, IPA withhold percentages were generally decreased in
1995, and as a result, the amounts owed to the IPAs tended to be paid over on a
more rapid schedule. Further, accelerated payments related to income taxes and
the Medicare cost contract decreased operating cash flows. These items were
partially offset by the net income of $16.0 million generated during the year.
Cash used for investing activities was $11.7 million for the year ended December
31, 1995, primarily due to capital expenditures of $15.2 million which
represented investments in optical imaging technology and other improvements in
the computer infrastructure needed to support the Company's expansion.

    Net cash flow during 1994 resulted in an increase in cash and investments to
$139.8 million at December 31, 1994 from $112.2 million at December 31, 1993.
Cash provided by operating activities totaled $39.3 million, resulting primarily
from net income of $14.1 million generated during the period, the timing of the
receipt of medical claims and the timing of payments related to other
liabilities.

    At December 31, 1994, PHS was no longer required to maintain a restricted
cash reserve to comply with the requirement of the Office of Prepaid Healthcare
in connection with the Medicare cost contract.  In New York, the Company is
required to maintain an escrow reserve equal to 5% of estimated health care
expenses for the current year, for the protection of enrollees, which, as of
December 31, 1996 was $9.0 million.  In Connecticut, the Company is required to
maintain a statutory minimum unimpaired capital surplus of $1.0 million.  The
Company is currently in compliance with all applicable statutory capital
requirements. The Company is subject to various laws and regulations which, at 
December 31, 1996, caused the aggregate amount of its restricted net assets to 
be approximately $38.8 million.

    The Company's expenditures for capital equipment, primarily for computers
and related equipment, and in 1996 for the purchase of the Company's new
headquarters, totaled $34.6 million, $15.2 million and $9.7 million for the
years ended December 31, 1996, 1995 and 1994, respectively. The Company expects
to spend additional capital, principally in computer and technology systems
enhancements, over the next several years. The Company expects to require
additional capital over the next several years and, although it can provide no
assurances in this regard, believes that in addition to its current capital
resources and internally generated funds, it will be able to obtain financing,
if necessary, sufficient for its continued operations.


EFFECT OF INFLATION

    Health care industry costs have been rising annually at rates higher than
the Consumer Price Index. To offset this trend, PHS has been able to achieve
premium rate increases for its 1997 business which should help mitigate the
effect of medical cost inflation on its operations. The Company's premiums are
higher than many of its competitors, however, and there can be no assurance that
the Company will be able to increase premiums sufficiently to offset the rise in
health care costs without jeopardizing the Company's competitive position. In
addition, PHS contracts with several major hospitals on a multi-year basis with
fixed annual increases. The

                                       23
<PAGE>
 
Company's risk sharing arrangements with its Physician Groups and other cost
control measures, such as its utilization review program, also help to mitigate
the effects of price increases on operations. There can be no assurance that the
Company's efforts to reduce the impact of inflation will be successful.


CAUTIONARY STATEMENT

    In connection with the "safe harbor" provisions of the Private Securities
Litigation Reform Act of 1995, the Company is hereby making cautionary
statements identifying important risk factors that could cause the Company's
actual results to differ materially from those projected in forward-looking
statements made by or on behalf of the Company.

    The Company wishes to caution readers that the following important factors,
among others, could cause the Company's actual financial or enrollment results
to differ materially from those expressed in any projected, estimated or
forward-looking statements relating to the Company.

PREMIUM STRUCTURE; UNPREDICTABILITY OF MEDICAL COSTS. A substantial amount of
the Company's revenues are generated by premiums which represent fixed monthly
payments for each person enrolled in the Company's plans. If the Company is
unable to obtain adequate premiums because of competitive or regulatory
considerations, the Company could incur decreased margins or significant losses.
The Company believes that commercial premium pricing will continue to be highly
competitive. The Company's revenues from its Medicare and Medicaid programs
could be adversely affected if reimbursement rates do not keep pace with rising
medical costs. Historically, these rates have been subject to wide variations
from year to year. In the event reimbursement were to decline from projected
amounts, the Company would attempt to renegotiate its contracts with its health
care providers. There can be no assurance that it could successfully renegotiate
these financial arrangements and failure to reduce the health care costs
associated with such programs could have a material adverse effect upon the
Company's business.

    The Company's profitability is also dependent, in large part, upon its
ability to accurately project and manage health care costs, including without
limitation, appropriate benefit design, utilization review and case management
programs, and its risk sharing arrangements with providers, while providing
members with quality health care.  Health care costs are affected by a variety
of factors that are difficult to predict and are not entirely within the
Company's control, including the severity and frequency of claims.  Medical cost
inflation, mandated benefits and other regulatory changes, new technologies,
natural disasters, epidemics and other external factors relating to the delivery
of health care services, inability to establish acceptable risk sharing
arrangements with providers and other factors may adversely affect the Company's
ability to manage the costs of providing health care services.  In addition, the
Company experienced high out-of-network utilization in connection with its POS
products in 1996 in New York, which resulted in medical costs for the POS
products exceeding budgeted amounts.  The Company is seeking to expand its
network in New York and institute other measures to limit the risk of high out-
of-network utilization.  The Company is implementing a variety of measures to
help it manage health care costs better.  However, there can be no assurance
that the Company will be able to continue to reduce its medical costs
sufficiently to restore profitability in all its product lines.  In light of the
expected continuing growth of the POS products, failure to reduce out-of-network
utilization could adversely affect the Company's profitability.

    Accrued health care expenses payable in the Company's financial statements
include reserves for incurred but not reported claims ("IBNR"), the amount of
which is estimated by the Company.  The Company estimates the amount of such
reserves using standard actuarial methodologies based upon historical data
including the average interval between the date services are rendered and the
date claims are paid, expected medical cost inflation, seasonality patterns and
increases in membership.  The Company believes that its reserves for IBNR are
adequate in order to satisfy its ultimate claims liability.  However, there can
be no assurances as to the ultimate accuracy or completeness of such estimates
or that adjustments to reserves will not cause volatility in the Company's
results of operations.

DEPENDENCE UPON KEY EMPLOYER AGREEMENTS.  The Company's ability to obtain and
maintain favorable group benefit agreements with employer groups affects the
Company's profitability.  Currently, 17% of its total 

                                       24
<PAGE>
 
commercial enrollment (those groups which are fully insured, which includes
332,363 enrollees) is derived from its largest five fully insured accounts.
Fully insured groups produce the highest PMPM revenues for the Company. Although
during the Company's most recent fiscal year, no employer group accounted for
more than 7.5% of total revenues, the loss of one or more of the larger employer
group accounts could have a material adverse effect upon the Company's business.
Although only 8% of the Company's total membership in 1996 was enrolled in
Medicare and Medicaid programs, that percentage is expected to increase in the
future. Loss of one or more of the contracts the Company currently has or
expects to have to serve Medicaid or Medicare participants could have a material
adverse effect upon the Company's business. Finally, the Company has agreed to
certain performance guarantees for certain of the large employer groups with
which it contracts. Failure to satisfy such guarantees could result in financial
penalties.

KEY PARTNERSHIP.  The Company's contracts with The Guardian are expected to
represent a significant percentage of the Company's revenue and enrollment in
future years.  See "Business-Joint Marketing Arrangement with The Guardian."
The loss of this relationship could have a material adverse effect on the
Company's business.


COMPETITION. Managed care companies and HMOs operate in a highly competitive
environment. The Company has numerous types of competitors, both local and
national, including, among others, HMOs, PPOs, self-insured employer plans and
traditional indemnity carriers, many of which have substantially larger total
enrollments, greater financial resources and other characteristics that give
them an advantage in competing with the Company. Additional competitors with
needs or desires for immediate market share or those with greater financial
resources than the Company have entered or may enter the Company's market. The
Company also believes that the addition of new competitors can occur relatively
easily. In addition, certain of the Company's customers may decide to perform
for themselves certain administrative services currently provided by the
Company, which could adversely affect the Company's revenues. Significant merger
and acquisition activity has occurred in the managed care industry as well as in
industries which are suppliers to the Company. This activity may result in
stronger competitors or increase health care costs. Increased competitive
pressures may limit the Company's ability to increase, or in some instances,
maintain premiums, reduce membership levels or decrease profit margins, and
there can be no assurance that the Company will not incur increased pricing and
enrollment pressure from local and national competitors. Any such pressures
could materially affect the Company's results of operations.

GOVERNMENT REGULATION.  The Company's business is subject to extensive federal
and state laws and regulations, including, but not limited to, financial
requirements, licensing requirements, enrollment requirements and periodic
examinations by governmental agencies.  The laws and regulations governing the
Company's business and the interpretation of those laws and regulations are
subject to frequent change.  Existing or future laws or regulations could force
the Company to change the way it does business and may restrict the Company's
revenue or enrollment growth or increase its health care and/or administrative
costs.  In particular, the Company's HMO and insurance subsidiaries are subject
to regulations relating to cash reserves, minimum net worth, premium rates and
approval of policy language and benefits.  Although such regulations have not
significantly impeded the growth of the Company's business to date, there can be
no assurance that the Company will be able to continue to obtain or maintain
required governmental approvals or licenses or that regulatory changes will not
have a material adverse effect on the Company's business.  In addition, delays
in obtaining regulatory approvals or moratoriums imposed by regulatory
authorities could adversely effect the Company's ability to bring new products
to market as forecasted.  The Company is also subject to various governmental
audits and investigations.  Such activities could result in the loss of required
licenses or the right to participate in certain programs, or the imposition of
penalties and/or other sanctions .  In addition, disclosure of any adverse
investigation or audit results or sanctions could negatively affect the
Company's reputation in various markets and make it more difficult for the
Company to sell its products and services.

MANAGEMENT INFORMATION SYSTEM.  The Company's management information system is
critical to its current and future operations.  The information gathered and
processed by the Company's management information system assists the Company in,
among other things, pricing its services, monitoring utilization and other cost
factors, processing provider claims, providing bills on a timely basis and
identifying accounts for collection.  Any difficulty associated with or failure
to successfully implement the current conversion of its management information
system, or any inability to expand processing capability in the future in
accordance with its business needs, could result in a loss of 

                                       25
<PAGE>
 
existing customers and difficulty in attracting new customers, customer and
provider disputes, regulatory problems, increases in administrative expenses or
other adverse consequences.

NEW SERVICE AREAS AND PRODUCTS.  The Company recently undertook a significant
expansion of its geographic market area.  In addition, it recently introduced
several new products, including Medicare risk and Medicaid products. The success
of its geographic and product expansion efforts depends in large part on its
ability to develop market share in a highly competitive market and to develop
the infrastructure necessary to support the forecasted enrollment growth.  The
Company believes that it has budgeted sufficient amounts to meet its growth
expectations; however, there can be no assurance that it will not require
greater resources than expected or that it will be successful in its marketing
efforts.  Furthermore, although it believes it has introduced programs to
effectively manage its new products, there can be no assurance that the health
care and other costs associated with such programs will not be greater than
revenues.  Medicare risk contracts provide revenues which are generally higher
per member than those for non-Medicare members, and thus provide an opportunity
for increased profits and cash flow.  Such risk contracts, however, also carry
certain risks such as higher comparative medical costs, government regulatory
and reporting requirements, the possibility of reduced or insufficient
government reimbursement in the future, and higher marketing and advertising
costs per member as the result of marketing to individuals as opposed to
groups.

POSSIBLE VOLATILITY OF COMMON STOCK PRICE. Recently, there has been significant
volatility in the market prices of securities of companies in the health care
industry, including the price of the Company's Common Stock. Many factors,
including medical cost increases, analysts' comments, speculation about a
possible merger or acquisition, announcements of new legislative proposals or
laws relating to health care reform, the performance of, and investor
expectations for, the Company, the trading volume of the Company's Common Stock
and general economic and market conditions, may influence the trading price of
the Company's Common Stock. Accordingly, there can be no assurance as to the
price at which the Company's Common Stock will trade in the future.

NEGATIVE PUBLICITY. The managed care industry has recently received a
significant amount of negative publicity. Such general publicity, or any
negative publicity regarding the Company in particular, could adversely affect
the Company's ability to sell its products or services or could create
regulatory problems for the Company. Recently, the managed care industry has
experienced significant merger and acquisition activity. Speculation or
uncertainty about the Company's future could adversely affect the ability of the
Company to market its products.

ACCREDITATION. Certain of the Company's customers or potential customers
consider rating, accreditation or certification of the Company by various
private or governmental bodies or rating agencies as necessary and/or important.
The Company currently has three year accreditation from the National Committee
on Quality Assurance ("NCQA") which will expire in May, 1997. NCQA visited the
Company's offices in connection with its reaccrediation in late March 1997.
Should the Company fail to maintain three-year NCQA accreditation, or obtain any
other certification or accreditation as may be deemed to be necessary and/or
important by customers, it may adversely affect the Company's ability to obtain
or retain the business of such customers.

ADMINISTRATIVE EXPENSE.  The level of administrative expense is a partial
determinant of the Company's profitability.  While the Company attempts to
effectively manage such expenses, increases in staff-related and other
administrative expenses may occur as a result of business or product expansion,
changes in business, acquisitions, regulatory requirements or other reasons.
Such expense increases are not clearly predictable and increases in
administrative expenses may adversely affect financial results.

The Company currently believes that it has a relatively experienced, capable
management staff.  Loss of certain managers or a number of such managers could
adversely affect the Company's ability to administer and manage its business.

LITIGATION AND INSURANCE.  The Company is subject to a variety of legal actions
to which any corporation may be subject.  In addition, because of the nature of
its business, the Company incurs and likely will continue to incur potential
liability for claims related to its business, such as failure to pay for or
provide health care, poor outcomes for care delivered or arranged, provider
disputes and claims related to self-funded business.  It is possible that
punitive or substantial non-economic damages may be sought in cases of this
nature.  While the Company currently has insurance coverage for some of
these potential liabilities, others may not be covered by insurance, the
insurers may dispute coverage or the amount of insurance may not be enough to
cover the damages awarded.  In 

                                       26
<PAGE>
 
addition, certain types of damages, such as punitive damages, may not be covered
by insurance and insurance coverage for all or certain forms of liability may
become unavailable or prohibitively expensive in the future.

PROVIDER RELATIONS.  One of the significant techniques that the Company uses to
manage health care costs and utilization is contracting with physicians,
hospitals and other providers.  Because of the large number of providers with
which the Company contracts, the Company currently believes that it has a
limited exposure to provider relations issues.  In any particular market,
however, providers could refuse to contract with the Company, demand higher
payments or take other actions which could result in higher health care costs,
less desirable products for customers and members or difficulty in meeting
regulatory or accreditation requirements.  In some markets,  certain providers,
particularly hospitals, physician/hospital organization or multi-speciality
physician groups, may have significant market positions.  Such groups may also
compete directly with the Company.  If such providers refuse to contract with
the Company or utilize their market position to negotiate favorable contacts or
place the Company at a competitive disadvantage, the Company's ability to market
products or to be profitable in those areas could be adversely affected.

In addition, the Company has recently entered into a number of contracts with
physician/hospital organizations and other physician groups that place a
significant percentage of the risk of overutilization on those groups.  Although
this technique is believed to be advantageous to the Company insofar as it
limits the Company's risk, failure of one or more of the physician/hospital or
other physician groups to successfully manage the risk could have a material 
adverse effect on the Company's business and results of operations.

                         Report of Independent Auditors



Board of Directors
Physicians Health Services, Inc.

We have audited the consolidated balance sheets of Physicians Health Services,
Inc. and subsidiaries as of December 31, 1996 and 1995, and the related
consolidated statements of operations, stockholders' equity, and cash flows for
the three years in the period ended December 31, 1996. Our audits also included
the financial statement schedules listed in the Index at Item 14(a). 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 consolidated financial position of Physicians Health
Services, Inc. and subsidiaries at December 31, 1996 and 1995, and the
consolidated results of their operations and their cash flows for each of the
three years in the period ended December 31, 1996, in conformity with generally
accepted accounting principles. Also, in our opinion, the related financial
statement schedules, when considered in relation to the basic financial
statements taken as a whole, present fairly, in all material respects, the
information set forth therein.

As discussed in Note 2 to the consolidated financial statements, in 1994 the
Company changed its method of accounting for certain investments in debt and
equity securities.

flow requirements and restrictions on the ability to pay dividends. Subscribers
pay monthly premiums which entitle them to comprehensive health services as
needed, according to the terms of their contracts.

PHIS, which is licensed as an insurance broker, was formed to market insurance 
products to enrollees. The operations of PHIS for all years presented were not 
significant.

PHS Insurance CT and PHS Insurance NY operate in and are regulated by the 
Insurance Departments of Connecticut and New York, respectively. These companies
are licensed to write accident and health indemnity insurance although no
business has yet been written.

PHS/Bermuda is an offshore property and casualty reinsurer that was formed to 
support the business needs of the Company. This includes an agreement to 
reinsure certain business with The Guardian Life Insurance Company of America 
(see Note 10).

PHS/CT operates throughout most of Connecticut with a significant portion of its
enrollees currently located in Fairfield County. PHS/NY operates only in New
York's Westchester, Putnam, Dutchess, Rockland and Orange Counties, and the
metropolitan New York City and Long Island regions. PHS/NJ operates throughout
New Jersey. The Company's membership consists of commercial, government and 
self-funded members.

PHS RE has a wholly owned subsidiary, PHS Real Estate II, Inc. (PHS RE II),
which owns the Company's new corporate headquarters. The operations of PHS RE
and PHS RE II were not significant.

The Company's managed care products include traditional HMO products, in both 
open access and gatekeeper models, point of service ("POS") products, 
administrative services only ("ASO") plans and Medicare and Medicaid plans.

The Company contracts with physician groups, such as IPAs, PHOs, and 
multi-specialty groups (collectively, "Physician Groups"), individual physicians
and other health care providers for a defined range of health services, 
including primary and specialty care. The Company's contracts with providers 
include discounted fee for service arrangements as well as capitated group 
arrangements in which the contracting Physician Group assumes a significant 
amount of the risk of overutilization. The Company currently has contracts with 
four IPAs, three PHOs and one large physician group ("Group") that provide for 
most of its physician services in its Connecticut service area.  In New York and
New Jersey, the Company generally contracts directly with physicians and 
other health care providers. Under the typical Physician Group arrangements, the
Physician Group receives a fixed monthly capitation payment for each member 
selecting a primary care physician from that Physician Group. Capitation rates 
and any increases thereto are negotiated for the term of the contract. The 
capitation payment is designed to cover not only the professional medical 
services (including ancillary tests and services) rendered by the physicians and
other providers associated with that Physician Group but also includes payments 
for certain other services rendered to the enrollee by providers who are not 
members of the Physician Group. Services covered by the capitation payment 
include, among other things, virtually all physician claims (whether inpatient 
or outpatient, including authorized out-of-plan care) and care rendered by other
professionals such as physical therapists and psychologists. In certain of the
contracts, the Physician Groups also are at risk for hospital, pharmacy and
other facility expenses. The Company does not capitate physicians directly.

The capitation payments to Physician Groups other than the PHOs typically do not
cover hospital and other facility expenses, although the Physician Groups are 
partially at risk for non-Medicare and non-Medicaid hospital utilization. The 
Company establishes an annual per member, per month target for hospital 
expenses. The amount varies by benefit plan and Physician Group, and encompasses
both inpatient and outpatient costs. If total hospital expenses generated by the
Physician Group exceed the applicable hospital expense target, the Company 
withholds from amounts owed by it to the Physician Group all or a portion of 
the excess over budget, in most cases one-half of the excess over budget. If 
actual costs are less than budgeted targets, the Physician Group receives from 
the Company an incentive credit typically equal to forty to fifty percent of the
amount by which actual costs are less than budgeted targets.

In its New York and New Jersey expansion areas and in areas in Connecticut not 
served through Physician Group contracts, the Company contracts for services 
principally through direct contracts with individual physicians and other health
care providers. In addition, the Company contracts with two IPAs in the northern
counties of its New York service area. The Company withholds a percentage of 
reimbursement for services rendered pursuant to its direct physician contracts 
against budgeted amounts to manage excessive utilization.

The Company generally negotiates contracts with hospitals that include 
compensation on a per diem basis (at a daily rate, without regard to the scope 
of services actually provided). Other compensation arrangements with hospitals 
include charged-based discounts (negotiated discounts from the hospital's billed
charges) and all inclusive case rates. In the case of non-participating 
hospitals, the Company pays either hospital billed charges or negotiated 
discounted charges. Additionally, some hospital contracts include per case, 
all-inclusive payment arrangements for select procedures such as maternity 
care.

1. ORGANIZATION AND BUSINESS (CONTINUED)

At December 31, 1996, three of the IPA's own common stock of the Company
aggregating approximately 32% (which entitle them to 68% of the vote on matters
submitted to the Stockholders), with one IPA (Greater Bridgeport Individual
Practice Association) owning approximately 27% (58% of the vote). Capitation
expenses incurred relating to these three IPA's which are included in physician
and related healthcare expenses in the accompanying statements of operations
amounted to $55,019,000, $68,523,000 and $65,091,000 for the years ended
December 31, 1996, 1995 and 1994 respectively. At December 31, 1996 and 1995
amounts payable to these IPA's were $21,622,000 and $10,388,000, respectively.

2. SIGNIFICANT ACCOUNTING POLICIES

PRINCIPLES OF CONSOLIDATION

The consolidated financial statements include the accounts of the Company and 
its subsidiaries, all of which are wholly-owned except for PHS/NJ which is 80% 
owned by the Company with a 20% minority interest owned by Mastercare 
Companies, Inc.  (See Note 11).  Such minority interest was not material to the 
accompanying consolidated financial statements.  Significant intercompany
accounts and transactions have been eliminated in consolidation.

USE OF ESTIMATES

The preparation of financial statements in conformity with generally accepted 
accounting principles requires management to make estimates and assumptions 
that affect the amounts reported in the financial statements and accompanying 
notes. Actual results could differ from those estimates.

REVENUE RECOGNITION

Premiums from subscribers and assumed or ceded under reinsurance agreements are 
reflected in operations as earned on a pro-rata basis over the period of 
coverage. Premiums for periods extending beyond year-end are classified as 
unearned premiums. The Company maintains an allowance for doubtful accounts at 
a level management believes is sufficient to cover potentially uncollectible 
amounts. 

PHYSICIANS AND RELATED HEALTH CARE SERVICES

The costs of physicians and related health care services are accrued for in the
period they are provided to enrollees. For the services provided for by
individually contracted physicians, the accrual for the incurred but not
reported claims represent the estimated liability on outstanding claims, based
upon an evaluation of reported claims. Such estimates are continually monitored
and, as estimates are adjusted, they are reflected in current operations. The
amounts accrued under capitation arrangements with IPA's are increased or
decreased based on a comparison of the HMO's hospitalization costs to
contractual targets.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

HOSPITAL AND OTHER HEALTH CARE SERVICES

The cost of health care services is accrued in the period they are provided to 
enrollees. The amounts accrued for hospital and other health care expenses 
represent the estimated liabilities for reported and unreported claims.  The
reserves for incurred but not reported claims represent the estimated liability
on outstanding claims, based on an evaluation of reported claims. The estimates
are continually monitored and reviewed and, as settlements are made or estimates
adjusted, the resulting differences are reflected in current operations.
Although considerable variability is inherent in such estimates, management
believes that reported reserves are adequate in the aggregate to cover the
ultimate resolution of incurred claims.

CONTRACTS WITH HEALTH CARE FINANCING ADMINISTRATION

Prior to 1996, the Company had entered into a "cost based" contract with the
Health Care Financing Administration ("HCFA"). Under this contract, HCFA pays
the Company a fixed per member per month amount for physician services, while
HCFA pays the costs for inpatient and outpatient services. During 1996, the
Company entered into a "risk based" contract with HCFA. Under the risk-based
contract the Company is paid a fixed per member, per month amount by HCFA for
all services provided. The Company bears the risk that the actual costs of
health care services may exceed the per member, per month amount. The risk based
contract is intended to replace the cost based contract for new enrollees.

PROPERTY, PLANT AND EQUIPMENT

Property, plant and equipment are stated at cost, less accumulated depreciation 
and amortization. Provisions for depreciation and amortization are computed 
using the straight-line method over the estimated useful lives of the assets or 
the terms of the leases, if shorter. Included in property, plant and equipment 
are the costs related to the development of a new managed care information 
system, approximately $18,600,000 at December 31, 1996. This new system is 
expected to be implemented in late 1997. Amortization of the cost of the new 
system will begin upon its implementation and continue on a straight-line basis 
over its estimated useful life.

EXCESS OF NET ASSETS OVER COST OF COMPANY ACQUIRED

The excess of net assets over the cost of company acquired is being amortized 
by the straight-line method over a 20 year period ending August 31, 2006. 
Accumulated amortization was $1,240,000 and $1,120,000 at December 31, 1996 and 
1995, respectively.

PER SHARE DATA

Per share data are based on the weighted average number of common and common 
equivalent shares outstanding during the period. Common stock equivalents 
consist of stock options. Fully diluted per share data are not presented as 
they are not materially different from primary earnings per share data.

2. SIGNIFICANT ACCOUNTING POLICIES (CONTINUED)

STOCK BASED COMPENSATION

In 1996, the Company implemented the supplemental pro forma provisions of
Statement of Financial Accounting Standards ("SFAS") No. 123, "Accounting for
Stock-Based Compensation" ("SFAS 123"). SFAS 123, if adopted, requires companies
to recognize compensation expense for grants of restricted stock, stock options
and similar equity instruments to employees and directors based on their
respective fair values at the date of grant. However, the provisions of
Accounting Principles Board ("APB") Opinion No. 25, "Accounting for Stock Issued
to Employees" ("APB 25") may still be utilized with supplemental pro forma
disclosures of net income and earnings per share being made in the footnotes as
if the accounting provisions of SFAS 123 had been adopted. SFAS 123 is effective
for fiscal years beginning after December 15, 1995. The Company continues to
apply the requirements of APB 25 in the accompanying financial statements with
supplemental pro forma disclosures provided in the notes to the consolidated
financial statements (See note 8).

CASH AND CASH EQUIVALENTS

Cash and cash equivalents consist of highly liquid investments with a maturity 
of three months or less at the time of purchase.

FAIR VALUE OF FINANCIAL INSTRUMENTS

Cash and cash equivalents, accounts receivable, other receivables, advances to 
participating hospitals and all current liabilities have fair values that 
approximate their carrying amounts.

INVESTMENTS

In May 1993, the Financial Accounting Standards Board issued SFAS 115, 
"Accounting for Certain Investments in Debt and Equity Securities." The Company 
adopted the provisions of the new standard as of January 1, 1994, and 
categorizes its investments in fixed maturity and equity securities as
"available for sale." Accordingly, such investments are reported at fair value
with changes in unrealized gains and losses disclosed separately, net of taxes,
in stockholders' equity. Fair values are based primarily on quoted market
prices.

Investment income includes realized investment gains and losses on the sale or 
maturity of investments, determined by the specific identification method, and 
dividends and interest, which are recognized when earned. The amortization of 
premium and accretion of discount for fixed maturities is computed utilizing 
the interest method.

INCOME TAXES

Income taxes have been provided using the liability method in accordance with 
SFAS 109, "Accounting for Income Taxes."

RECLASSIFICATIONS

Certain reclassifications were made to conform prior year amounts to current 
year presentation.

3. EXCESS OF LOSS REINSURANCE AGREEMENT

During 1996 the Company limited the amount of its risk on eligible hospital
claims for any one member in a contract year by acquiring reinsurance coverage
for claims in excess of $600,000 per member, per year for PHS/CT, PHS/NY and
PHS/NJ. The reinsurance contracts allow the Company to transfer to the reinsurer
80% of the next $400,000 of claims per member per year. The contract limits
covered claims to $2 million per member per lifetime (including the deductible).
During 1995 and 1994, the Company acquired reinsurance coverage for claims in
excess of $250,000 per member, per year for PHS/CT and $100,000 per member, per
year for PHS/NY. Those reinsurance policies allowed the Company to transfer to
the reinsurer 80% of the next $750,000 (PHS/CT) and $900,000 (PHS/NY) of the
amount of claims in excess of the aforementioned annual retentions. Reinsurance
expense and recoveries are included in other health care services.

Reinsurance expense was $910,000, $1,300,000, and $636,000, for 1996, 1995 and 
1994, respectively. Recoveries were $311,000, $60,000, and $106,000 for 1996, 
1995, and 1994, respectively.

7. COMMITMENTS AND CONTINGENCIES 

The Company is involved in various litigation and claims arising in the normal 
course of business which management believes, based upon discussions with legal 
counsel, will not have a material adverse effect on the accompanying financial 
statements.

During 1996, the Company entered into a revolving credit agreement under which 
it borrowed $18 million to provide short-term financing for the 
purchase of the Company's new headquarters. In the fourth quarter the Company 
repaid amounts due under the credit agreement and terminated the credit line.
Total interest expense paid in connection with this agreement was approximately
$388,000.

The Health Reinsurance Association ("HRA") provides for otherwise unavailable 
health insurance coverage to uninsured or underinsured Connecticut residents.  
All health insurers, including HMOs, licensed in Connecticut are subject to 
assessment by the HRA to the extent the HRA incurs net losses.  Assessments are 
based on premiums written and amounted to $1,018,000, $692,000, and $800,000 in 
1996, 1995 and 1994, respectively.

PHS/NY is subject to a community rating law which establishes a pooling 
mechanism providing for payments to insurers writing policies for a 
disproportionate share of individuals with certain demographic characteristics 
and catastrophic medical expenses. Depending on the age and sex characteristics 
of an insurer's members, an insurer will either make payments to or receive 
payments from the state pooled fund. Expenses related to the demographic pool 
were $3,180,000 in 1996, $1,483,000 in 1995 and $1,152,000 in 1994.

For further commitments, refer to Note 11.

8. EMPLOYEE BENEFIT AND STOCK OPTION PLANS

The Company sponsors a defined contribution pension plan covering all full-time 
eligible employees (as defined). Contributions are based on a percentage of 
eligible salaries as determined by the Board of Directors. This plan also 
allows for additional voluntary contributions by covered full-time employees. 
Pension cost was approximately $1,061,000 in 1996, $853,000 in 1995 and 
$696,000 in 1994. The Company also has a 401(k) plan which covers substantially 
all eligible employees (as defined). This plan allows for voluntary employee 
contributions and a corporate match of 75% up to 4% of each employee's 
compensation. In addition, the Company contributes 1% of each eligible 
employee's compensation (as defined) to the plan. Expense related to the 401(k)
plan was $858,000 in 1996, $654,000 in 1995, and $519,000 in 1994.

The Company's Board of Directors, on November 17, 1992, and subsequently on 
November 21, 1995, adopted two Stock Option Plans (the "Plans") under 
which the Company may grant to certain officers and key employees (and, under
the 1995 Plan, directors) incentive and nonqualified stock options for up to an
aggregate maximum of 1,400,000 shares of Class A Common Stock. Under the Plans,
the Board or Compensation Committee sets the exercise price for such options,
but for incentive stock options, the exercise price shall not be less than the
fair market value of the stock at the date of grant. Under the Plans, options
may be exercised only at such times and under such conditions as determined by
the Board or the Compensation Committee, but in no event more than ten years
after the date of grant. The options that have been granted to date become
exerciseable in equal installments over a period of three years and expire after
ten years except for ten percent shareholders for which such options expire five
years after the grant dates and certain performance based options granted in
1996, whose vesting may be accelerated based upon achievement of certain
earnings targets.

Supplemental and Pro Forma Disclosure:

The following pro forma information regarding net income (loss) and net income 
(loss) per share, required by SFAS 123, has been determined as if the Company
had accounted for its stock-based compensation plans under the fair value
methods described in that statement. The fair value of options granted under the
Company's stock-based compensation plans was estimated at the date of grant
using a Black-Scholes option pricing model. The Black-Scholes option pricing
model was developed for use in estimating the fair value of traded options which
have no vesting restrictions and are fully transferable. In addition, option
pricing models require the input of highly subjective assumptions including the
expected dividend yield, the expected life of the options, the expected price
volatility and the risk free interest rate. The weighted averages of the 
assumptions used are set forth in the following paragraph.

The weighted average dividend yield for stock option grants during 1996 and 
1995 was 0%. The weighted average expected life for 1996 and 1995 was 5 years. 
The weighted average volatility for 1996 and 1995 was .46%. The weighted 
average risk-free interest rate for 1996 and 1995 was 5.87% and 6.99%, 
respectively.

For purposes of pro forma disclosure, the estimated fair values of the options 
awarded are amortized to expense over the options' vesting period and do not 
include grants prior to January 1, 1995. As such, the pro forma information is
not indicative of future years. The Company's pro forma information was as
follows (in thousands, except per share data):

9. DIVIDEND AND INVESTMENT RESTRICTIONS OF SUBSIDIARIES

The Company's HMO and insurance subsidiaries are subject to statutory 
regulations that restrict the payment of dividends. Based on laws currently in 
effect, PHS/CT generally may not pay dividends in excess of the greater of (1) 
the net gain from operations for the preceding calendar year, or (2) 10% of 
capital and surplus as of the preceding year end, both as determined in 
accordance with statutory accounting practices, without receiving approval of 
the Connecticut Insurance Commissioner. The maximum amount of cash dividends 
that PHS/CT could pay in 1997 without regulatory approval is approximately
$2,800,000.

The Company is required by the State of New York to maintain an escrow reserve, 
currently held in U.S. government obligations, equal to 5% of PHS/NY's 
estimated health care expenses for the upcoming year. The escrow reserve was 
approximately $9,113,000 and $7,087,000 at December 31, 1996 and 1995, 
respectively.

The Company is required by the New Jersey State Insurance Department to 
maintain an escrow reserve of $300,000 in the event of insolvency. The escrow 
reserve was approximately $322,000 at December 31, 1996.

Based on statutory rules and restrictions, the amount of restricted net assets 
of consolidated subsidiaries at December 31, 1996 was approximately $38.8 
million.

10. ARRANGEMENT WITH THE GUARDIAN LIFE INSURANCE COMPANY OF AMERICA

In 1995, the Company's subsidiaries, PHS/CT, PHS/NY and PHS/Bermuda, entered 
into several marketing and reinsurance agreements with The Guardian Life 
Insurance Company of America ("Guardian") and, together, the "companies". 
Under these agreements, jointly developed managed care and indemnity products 
are marketed to existing insureds of Guardian. In addition, the companies 
distributed these products through the brokerage community and an integrated
marketing effort by the companies under the trade name "Healthcare Solutions."

In 1995 and for the first nine months of 1996, PHS/CT, under the terms of the 
marketing agreement, wrote 100% of the HMO/POS business and Guardian wrote 100% 
of the indemnity business in Connecticut. Under the terms of the profit sharing
agreement, a profit or loss was determined for each line of business. If both
lines were profitable, profits, after provisions for related expenses, as
defined, were shared equally. If neither line were profitable, each company
retained losses, after provisions for related expenses, for its line of business
written. If one line was profitable and the other unprofitable, payments, as
defined, were to be made by the company writing the profitable line to the
company with the unprofitable line, before net profits, if any, were shared. In
connection with this agreement, PHS/CT reported losses of $7.6 million for the
HMO/POS business.

As of October 1, 1996, PHS/CT writes 100% of the HMO/POS business and, under the
terms of a quota share reinsurance agreement, cedes 50% of it to Guardian.
Accordingly, profits and losses, after provisions for related expenses, as
defined, are shared equally. Additionally, 50% of losses previously reported
under the agreement discussed in the preceeding paragraph are recoverable from
future profits, if any, under the reinsurance agreement. After September 30,
1996, PHS/CT no longer participates in the indemnity business.

In 1995, PHS/NY wrote the HMO/POS In-Network business and, under the terms of a
quota share reinsurance agreement, ceded 50% of it to Guardian, while Guardian
wrote 100% of the Indemnity/POS Out-of-Network business and, under the terms of
a quota share reinsurance agreement with PHS/Bermuda, ceded 50% of it to PHS/
Bermuda. As such, profits and losses, after provisions for related expenses, as
defined, were shared equally.

From January 1, 1996 to June 30, 1996, PHS/NY's participation in the Indemnity 
business was reduced from 50% to 10%. After June 30, 1996, PHS/NY no longer
participates in the Indemnity business.

10. AGREEMENT WITH THE GUARDIAN LIFE INSURANCE COMPANY OF AMERICA (CONTINUED)

In 1996, PHS/NJ entered into marketing and reinsurance agreements with Guardian.
PHS/NJ writes the HMO/POS In-Network business and, under the terms of the quota
share reinsurance agreement, cedes 50% of it to Guardian PHS/NJ writes the
HMO/POS out-of-network business and under the terms of a quota share reinsurance
agreement, ceded 100% of it to Guardian, who retrocedes 50% of it back to PHS.
As such, profits and losses, after provisions for related expenses, as defined,
are shared equally.

In 1996, these jointly marketed products generated approximately $114.5 million
of revenue and $129.1 million of medical costs and other expenses for PHS.

In 1995, these jointly marketed products generated approximately $21.5 million
of revenue and $20.2 million of medical costs and other expenses for PHS.

Other receivables at December 31, 1996 and 1995 includes amounts due from
Guardian under profit sharing and reinsurance agreements of approximately $18.4
million and $11.8 million, respectively.

In October 1996, Guardian canceled its warrant that was issued by the 
Company in 1995, which originally provided for the purchase of one million 
shares of the Company's Class A common stock, once certain operating conditions 
had been met. Based upon a subsequent agreement with Guardian, the number 
of shares available for purchase under the warrant at the time it was canceled 
had been substantially reduced as a result of the Guardian's purchase of shares 
of the Company's Class A common stock on the open market. The Company had not 
recognized any expense related to the warrant as the conditions to its 
exercisability had not been met, nor was it deemed probable that they would be 
met up to the date of cancellation.

11. SALE OF TEC AND INVESTMENT IN MASTERCARE COMPANIES, INC.

In September 1995, the Company sold 81% of its wholly-owned subsidiary Total
Employee Care, Inc. to Mastercare Companies, Inc. (Mastercare) for 625,000
voting shares of Mastercare common stock. In addition, the Company purchased
additional shares of Mastercare voting stock in the amount of 1,250,000 shares
at $1.20 per share. The Company owns less than 20% of the voting stock and does
not have the ability to exercise significant influence over the operating and
financial policies of Mastercare and, accordingly has reported this investment
at the lower of cost or market.

        related to this Plan shall be determined unilaterally by and at the sole
        discretion of the Compensation Committee.

 E.     Amendment or Termination. The Board may, at any time, alter, amend,
        ------------------------
        suspend, discontinue, or terminate this Plan; provided, however, that

        Options previously granted.

                        INCENTIVE STOCK OPTION PROVISION

A.      Granting of Incentive Stock Options.
        -----------------------------------

        (1)  Incentive Stock Options shall be available for grant under the Plan
             only in the event that a majority of the stockholders of the
             Company approve the adoption of the Plan.

        (2)  Only key Employees of the Employer shall be eligible to receive
             Incentive Stock Options under the Plan. Directors of the Company
             who are not also Employees shall not be eligible for Incentive
             Stock Options.

        (3)  The purchase price of each share of Stock subject to an Incentive
             Stock Option shall not be less than 100% of the Fair Market Value
             of a share of the Stock on the date the Incentive Stock Option is
             granted; provided, however, that the purchase price of each share
             of Stock subject to an Incentive Stock Option granted to a Ten
             Percent Stockholder shall not be less that 110% of the Fair Market
             Value of a share of the Stock on the date the Incentive Stock
             Option is granted.

        (4)  No Incentive Stock Option shall be exercisable more than ten years
             from the date the Incentive Stock Option was granted; provided,
             however, that an Incentive Stock Option granted to a Ten Percent
             Stockholder shall not be exercisable more than five years from the
             date the Incentive Stock Option was granted.

        (5)  The Compenstion Committee shall determine and designate from time
             to time those Employees who are to be granted Incentive Stock
             Options and specify the number of shares subject to each Incentive
             Stock Option and such other terms, including vesting requirements
             and the minimum number of options exercisable at a time.

        (6)  Notwithstanding any other provisions hereof, the aggregate Fair
             Market Value (determined at the time the option is granted) of the
             Stock with respect to which Incentive Stock Options are exercisable
             for the first time by the Employee during any calendar year (under
             all such plans of the Grantee's employer corporation and its parent
             and subsidiary corporations) shall not exceed $100,000.

        (7)  The Compensation Committee, in its sole discretion, shall determine
             whether any particular Incentive Stock Option shall become
             exercisable in one or more installments, specify the installment
             dates, and, within the limitations herein provided, determine the
             total period during which the Incentive Stock Option is
             exercisable. Further, the Compensation Committee may make such
             other provisions as may appear generally acceptable or desirable to
             the Compensation Committee or necessary to qualify its grants under
             the provisions of Section 422 of the Code.
<PAGE>
 
        (8)  The Compensation Committee may grant at any time new Incentive
             Stock Options to an Employee who has previously received Incentive
             Stock Options or other options whether such prior Incentive Stock
             Options or other options are still outstanding, have previously
             been exercised in whole or in part, or are canceled in connection
             with the issuance of new Incentive Stock Options. The purchase
             price of the new Incentive Stock Option may be established by the
             Compensation Committee without regard to the existing Incentive
             Stock Options or other options.

B.      Exercise of Incentive Stock Options.
        -----------------------------------

        (1)  The option price of an Incentive Stock Option shall be payable on
             exercise of the option (i) in cash or by check, bank draft or
             postal express money order, (ii) by promissory note, (iii) by the
             surrender of Stock or Class B Common Stock then owned by the
             Grantee, provided that the stock surrendered by the Grantee has
             been owned by the Grantee for at least six (6) months, or (iv) a
             combination of clauses (i), (ii) or (iii). Shares of Stock or Class
             B Common Stock so surrendered in accordance with clause (iii) or
             (IV) shall be valued at the Fair Market Value thereof on the date
             of exercise, surrender of such Stock or Class B Common Stock to be
             evidenced by delivery of the certificate(s) representing such
             shares in such manner, and endorsed in such form, or accompanied by
             stock powers endorsed in such form, as the Compensation Committee
             may determine.

C.      Termination of Employment.
        -------------------------

        (1)  If a Grantee's employment is terminated (other than by Disability
             or death) the terms of any then outstanding Incentive Stock Option
             held by the Grantee shall extend for a period ending on the earlier
             of the date on which such option would otherwise expire or three
             months after such termination of employment, and such option shall
             be exercisable to the extent it was exercisable as of the date of
             termination of employment.

        (2)  If a Grantee's employment is terminated by reason of Disability,
             the term of any then outstanding Incentive Stock Option held by the
             Grantee shall extend for a period ending on the earlier of the date
             on which such option would otherwise expire or twelve months after
             the Grantee's last date of employment, and such option shall be
             exercisable to the extent it was exercisable as of such last date
             of employment.

        (3)  If a Grantee's employment is terminated by death, the
             representative of his estate or beneficiaries thereof to whom the
             option has been transferred shall have the right during the
             three-month period following his death to exercise any then
             outstanding Incentive Stock Options in whole or in part. If a
             Grantee dies within three months after his retirement without
             having fully exercised any then outstanding Incentive Stock
             Options, the representative of his estate or beneficiaries thereof
             to whom the option has been transferred shall have the right during
             such three-month period to exercise such options in whole or in
             part. The number of shares of Stock in respect of which an
             Incentive Stock Option may be exercised after a Grantee's death
             shall be the number of shares in respect of which such option could
             be exercised as of the date of the Grantee's death or retirement,
             whichever occurs first. In no event may the period for exercising
             an Incentive Stock Option extend beyond the date on which such
             option would otherwise expire.

        (4)  The Board may grant a leave of absence to any Grantee for purposes
             of continuing such Grantee's employment with the Employer.

        (1)  Only key Employees of the Employer and Directors shall be eligible
             to receive Non-Qualified Stock Options under the Plan.

        (2)  The Compensation Committee shall determine and designate from time
             to time those Employees who are to be granted Non-Qualified Stock
             Options and the amount subject to each Non-Qualified Stock Option.

        (3)  The Compensation Committee may grant at any time new Non-Qualified
             Stock Options to an Employee who has previously received
             Non-Qualified Stock Options or other options, whether such prior
             Non-Qualified Stock Options or other options are still outstanding,
             have previously been exercised in whole or in part, or are canceled
             in connection with the issuance of new Non-Qualified Stock Options.

        (4)  When granting a Non-Qualified Stock Option, the Compensation
             Committee shall determine the purchase price of the Stock subject
             thereto. Such price may be less that 100% of the Fair Market Value
             of such stock on the date the Non-Qualified Stock Option is
             granted.

        (5)  The Compensation Committee, in its sole discretion, shall determine
             whether any particular Non-Qualified Stock Option shall become
             exercisable in one or more installments, specify the installment
             dates, and, within the limitations herein provided, determine the
             total period during which the Non-Qualified Stock Option is
             exercisable. Further, the Compensation Committee may make such
             other provisions as may appear generally acceptable or desirable to
             the Compensation Committee.

        (1)  The option price of a Non-Qualified Stock Option shall be payable
             on exercise of the option (i) in cash or by check, bank draft or
             postal or express money order, (ii) by promissory note, (iii) by
             the surrender of Class B Common Stock or Stock then owned by the
             Grantee provided that the Stock surrendered has been held by for at
             least six months, or (iv) by a combination of clauses (i), (ii) and
             (iii). Shares of Class B Common Stock or Stock so surrendered in
             accordance with clause (iii) or (iv) shall be valued at the Fair
             Market Value thereof on the date of exercise, surrender of such to
             be evidenced by delivery of the certificate(s) representing such
             shares in such manner, and endorsed in such form, or accompanied by
             stock powers endorsed in such form, as the Compensation Committee
             may determine.

C.      Termination of Employment.
        -------------------------

        (1)  If a Grantee's employment is terminated (other than by Disability
             or death), the terms of any then outstanding Non-Qualified Stock
             Option held by the Grantee shall extend for a period ending on the
             earlier of the date on which such option would otherwise expire or
             three months after such termination of employment and such option
             shall be exercisable to the extent it was exercisable as of the
             date of termination of employment.
<PAGE>
 
        (2)  If a Grantor's employment is terminated by reason of Disability,
             the term of any then outstanding Non-Qualified Stock Option held by
             the Grantee shall extend for a period ending on the earlier of the
             date on which such option would otherwise expire or twelve months
             after the Grantee's last date of employment, and such option shall
             be exercisable to the extent it was exercisable as of such last
             date of employment.

        (3)  If a Grantee's employment is terminated by death, the
             representative of his estate or beneficiaries thereof to whom the
             option has been transferred shall have the right during the
             three-month or less period following his death to exercise any then
             outstanding Non-Qualified Stock Options in whole or in part. If a
             Grantee dies within three months after his retirement without
             having fully exercised any then outstanding Non-Qualified Stock
             Options, the representative of his estate or beneficiaries thereof
             to whom the option has been transferred shall have the right during
             such three month period to exercise such options in whole or in
             part. The number of shares of Stock in respect of which a
             Non-Qualified Stock Option may be exercised after a Grantee's death
             shall be the number of shares of Stock in respect of which such
             option could be exercised as of the date of the Grantee's death or
             retirement, whichever first occurs. In no event may the period for
             exercising a Non-Qualified Stock Option extend beyond the date on

        (4)  The Board may grant a leave of absence to any Grantee for purposes
             of continuing such Grantee's employment with the Employer.

             Plan, as the Board shall approve.

        (2)  The granting of a Stock Option in any year shall not give the
             Grantee any right to similar grants in future years or any right to
             be retained in the employ of the Employer, and all Employees shall
             remain subject to discharge to the same extent as if the Plan were
             not in effect.

        (3)  No employee, and no beneficiary or other person claiming under or

                  any state or federal law or regulation, or the maintaining in
                  effect of any such registration or other qualification which

             jurisdiction thereof. The Grantee may be required to pay to the
             Employer the amount of any withhold taxes which the Employer is

             or part of the amount required to be withheld.

        (7)  In the case of a grant of a Stock Option to any Employee of a
             subsidiary of the Company, the Company may, if the Compensation

             by the Stock Option to the subsidiary, for such lawful
             consideration as the Compensation Committee may specify, upon the

             shares to the Employee in accordance with the terms of the Stock
             Option specified by the Compensation Committee pursuant to the
             provisions of the Plan. For purposes of this Section, a subsidiary
             shall mean any subsidiary corporation of the Company as defined in

        (8)  A Grantee entitled to Stock as a result of the exercise of an
             option shall not be deemed for any purpose to be, or have rights
             as, a stockholder of the Employer by virtue of such exercise,
             except to the extent a stock certificate is issued therefor and
             then only from the date such certificate is issued. No adjustments
             shall be made for dividends or distributions or other rights for
             which the record date is prior to the date such stock certificate
             is issued. The Employer shall issue any stock certificates required
             to be issued in connection with the exercise of a Stock Option with
             reasonable promptness after such exercise.

        (9)  The grant or exercise of Stock Options granted under the Plan shall
             be subject to, and shall in all respects comply with, applicable
             Delaware corporate law relating to such grant or exercise.

shares of the Corporation's Class A Common Stock pursuant to the Incentive Stock
Option provisions contained in Article II of the Plan, on the terms and
conditions hereinafter set forth, at the purchase price of $_______ per share
(such shares, number of shares and purchase price being subject to adjustment as
provided in Paragraph A of Article IV of the Plan).

        2. Terms of Plan. The Plan, a copy of which is attached hereto, is
           -------------
incorporated herein by reference and is made part of this Agreement as if fully
set forth herein. This Agreement is subject to, and the Corporation and the
Grantee agree to be bound by, all of the terms and conditions of the Plan as the
Plan exists at the time of this Agreement's execution. The Plan shall control in
the event there is any express conflict between the Plan and the terms hereof,
and on such matters that are not expressly covered in this Agreement. Subsequent
amendments of the Plan shall not adversely affect the Grantee's rights under
this Agreement.

        3. Exercise of Option. The Stock Option granted pursuant to this
           ------------------
Agreement is exercisable in accordance with the vesting schedule approved by the
Compensation Committee, as set forth below.

        Installments, if applicable, shall be cumulative, but each exercise must
encompass at lease one installment of _____ shares, whichever is less. In the
event the Grantee's exercise includes a fractional share, the Corporation will
not be required to issue a fractional share but will pay the Grantee in Cash the
value of such fraction. All unexercised rights shall lapse and forever terminate
after the expiration of ten years from the date of this Agreement, provided,
however, that all unexercised rights granted to ten percent stockholders shall
lapse and forever terminate after the expiration of five years from the date of
this Agreement.

        4. Termination of Employment. If the Grantee's employment is terminated
           -------------------------
(other than by Disability or death) the terms of any then outstanding Incentive
Stock Option held by the Grantee shall extend for a period ending on the earlier
of the date on which such option would otherwise expire or three 
<PAGE>
 
months after such termination of employment, and such option shall be
exercisable to the extent it was exercisable as of the Grantee's last date of
employment.

If a Grantee's employment is terminated by reason of Disability, the term of any
then outstanding Incentive Stock Option held by the Grantee shall extend for a
period ending on the earlier of the date on which such option would otherwise
expire or twelve months after the Grantee's last date of employment, and such
option shall be exercisable to the extent it was exercisable as of the Grantee's
last date of employment.

If a Grantee's employment is terminated by death, the representative of his
estate or beneficiaries thereof to whom the option has been transferred shall
have the right, during the period ending on the earlier of the date on which
such option would otherwise expire or three months after such termination of
employment, or exercise such options in whole or in part. If a Grantee dies
without having fully exercised any then outstanding Incentive Stock Options, the
representative of his estate of beneficiaries thereof to whom the option has
been transferred shall have the right to exercise such options in whole or in
part during the then existing exercise period. The number of shares of Stock in
respect of which an Incentive Stock Option may be exercised after a Grantee's
death shall be the number of shares in respect of which such option could be
exercised as of the Grantee's last date of employment.

        5. Manner of Exercise. Full payment for the shares of Stock purchased
           ------------------
shall be made at the time of any exercise of this Agreement. The purchase price
shall be payable to the Corporation either (i) in cash or by check, bank draft,
or postal or express money order, (ii) by promissory note, (iii) through the
delivery of shares of Class A or Class B Common Stock then owned by the Grantee
having a Fair Market Value on the date of exercise equal to the full purchase
price, provided that the shares so delivered have been owned by the Grantee for
at least six (6) months, or (iv) by a combination of (i), (ii) or (iii) above;
provided, however, that no fractional share shall be accepted by the Corporation
in partial payment of the purchase price of any Stock, and the value of any such
fractional interest shall be paid to the Corporation in the manner specified in
(i) above.

Subject to the terms and conditions hereof, the options shall be exercisable by
notice to the Corporation on the form provided by the Corporation, a copy of
which is attached hereto. In the event that the options are being exercised by
any person or persons other than the Grantee, the notice shall be accompanied by
proof, satisfactory to the Corporation, of the right of such person or persons
to exercise any right under this Agreement.

        6. Rights of Grantee. The grant of an option in any year shall give such
           -----------------
Grantee neither any right to similar grants in future years nor any right to be
retained in the employ of the Corporation or any of its subsidiaries, such
employment being terminable to the same extent as if the Plan and this Agreement
were not in effect.

Neither the Grantee nor any other person legally entitled to exercise any rights
under this Agreement shall be entitled to any of the rights or privileges of a
stockholder of the Corporation with respect to any shares which may be issuable
upon any exercise pursuant to this Agreement, unless and until a certificate or
certificates representing such shares shall have been actually issued and
delivered to the Grantee or such person.

        7. Non-Transferability of Option. Except as otherwise provided herein,
           -----------------------------
an option and the rights and privileges conferred hereby may not be transferred,
assigned pledged or hypothecated in any way, other than by will or the laws of
descent and distribution, and an option shall be exercisable during the
Grantee's lifetime only by the Grantee or his conservator.

        8. Taxes and Withholding. All payments to Grantee or to his legal
           ---------------------
representative shall be subject to any applicable tax, community property, or
other statutes or regulations of the United States or of any state having
jurisdiction thereof. The Grantee may be required to pay to the Corporation the
amount of any withholding taxes which the Corporation is required to withhold
with respect to a Stock option or its 
<PAGE>
 
exercise. In the event that such payment is not made when due, the Corporation
shall have the right to deduct, to the extent permitted by law, from any payment
of any kind otherwise due to such person all or part of the amount required to
be withheld.

        9. Premature Disposition of Shares. If the Grantee or Grantee's estate
           -------------------------------
sells or otherwise disposes of any shares acquired upon exercise of this option
within one year from the date of shares involved were acquired or two years from
the date of this Agreement, the Grantee (or such person exercising this option)
agrees that the Grantee or the Grantee's estate will deliver a written report to
the Secretary of the Corporation within 30 days following the sale or other
disposition, which report shall set forth the date of sale or other disposition
of said shares and the net proceeds of such sale or disposition.

        10. Notices. Each notice relating to this Agreement shall be in writing

the Grantee or such other person or persons at the Grantee's address specified
below or at such other address as the Grantee or such other person may specify
in writing to the Corporation by a notice delivered in accordance with this
paragraph.

        11. Restriction on Shares. The Corporation's obligation to issue or
            ---------------------
deliver any certificate for shares of Stock under this option, and the
transferability of shares acquired by the exercise of this option, shall be
subject to all of the following conditions:

        (a)  Any registration or other qualification of such shares under any
             state or federal law or regulation, or the maintaining in effect of
             any such registration or other qualification which the Corporation
             shall in its absolute discretion upon the advice of counsel, deem
             necessary or advisable; and

        (b)  The obtaining of any other consent, approval, or permit from any
             state or federal governmental agency which the Corporation shall,
             in its absolute discretion upon the advice of counsel, determine to
             be necessary or advisable.

        (c)  Each stock certificate issued pursuant to exercise of this option
             shall bear the following legend:

LETTER OF STOCK OPTION GRANT







                                            ______________ 1994

(Grantee)





Dear _________

I am pleased to confirm that you have been awarded an Incentive Stock Option
under the Physicians Health Services, Inc. 1995 Stock Option Plan. Enclosed are
two copies of an Incentive Stock Option Agreement, which have been signed by
Physicians Health Services, Inc. Please sign both copies and return one to me in
the enclosed envelope.

Also enclosed are copies of the Physicians Health Services, Inc. 1995 Stock
Option Plan and the form to be used based upon exercise of any part of the
option.

The option covers shares of Class A Common Stock of Physicians Health Services,
Inc. and becomes exercisable in installments over the next _____ years, provided
you remain in the employment of Physicians Health Services, Inc. In addition,
the shares covered by this option have not been registered under state or
federal securities laws. Accordingly, under these laws, until such time as an
effective registration statement is filed or an exemption becomes available with
respect to these shares, there are prohibitions upon the exercise of this option
and the later sale of any shares purchased under this option. These prohibitions
stem from the securities laws and will be discussed with you at a later date.

Meanwhile, we wish to forward the copies of the option agreement to you at this
time.

                                   Sincerely,

                                                                       ---------

                        PHYSICIANS HEALTH SERVICES, INC.

                    1995 NON-QUALIFIED STOCK OPTION AGREEMENT

        Agreement made this ______ day of ___________, _____ between Physicians
Health Services, Inc., a corporation organized under the laws of the State of
Delaware (hereinafter called the "Corporation" and _____________ (herein after
called the "Grantee").

        WHEREAS, the Corporation desires to provide the Grantee with an
opportunity to acquire or increase his proprietary interest in the business of
the Corporation and, through stock ownership, to possess an increased personal
interest in its continued success and progress;

        NOW, THEREFORE, in consideration of the premises, the mutual covenants
hereinafter set forth, and other good and valuable consideration, the
Corporation and the Grantee agree as follows:

        1. Award of Option. The Corporation hereby awards to the Grantee, as a
           ---------------
matter of separate inducement and agreement, and not in lieu of salary or any
other compensation for services, an option or purchase an aggregate of _____
shares of the Corporation's Class A Common Stock pursuant to the Non-Qualified
Stock Option provisions contained in Article III of the Plan, on the terms and
conditions hereinafter set forth, at the purchase price of $17.00 per share
(such shares, number of shares and purchase price being subject to adjustment as
provided in Paragraph A of Article IV of the Plan).

        2. Terms of the Plan. The Plan, a copy of which is attached hereto, is
           -----------------
incorporated herein by reference and is made part of this Agreement as if fully
set forth herein. This Agreement is subject to, and the Corporation and the
Grantee agree to be bound by, all of the terms and conditions of the Plan as the
Plan exists at the time of this Agreement's execution. The Plan shall control in
the event there is any express conflict between the Plan and the terms hereof,
and on such matters that are not expressly covered in this Agreement. Subsequent
amendments of the Plan shall not adversely affect the Grantee's rights under
this Agreement.

        3. Exercise of Option. The Stock Options granted pursuant to this
           ------------------
Agreement are exercisable in accordance with the vesting schedule approved by
the Compensation Committee, as set forth below.

        Installments, if applicable, shall be cumulative, but each exercise must
encompass at least one installment of 100 shares, whichever is less. In the
event the Grantee's exercise includes a fractional share, the Corporation will
not be required to issue a fractional share but will pay the Grantee in Cash the
value of such fraction. All unexercised rights shall lapse and forever terminate
after the expiration of ten years from the date of this Agreement.

        4. Termination of Employment. If the Grantee's employment is terminated
           -------------------------
(other than by Disability or death), the terms of any then outstanding
Non-Qualified Stock Option held by the Grantee shall extend for a period ending
on the earlier of the date on which such option would otherwise expire or three
months after such termination of employment, and such option shall be
exercisable to the extent it was exercisable as of the Grantee's last date of
employment.

If the Grantee's employment with the Corporation is terminated by reason of
Disability, the term of any then outstanding Non-Qualified Stock Option held by
the Grantee shall extend for a period ending on the earlier of the date on which
such option would otherwise expire or twelve months after such termination of
employment, and such option shall be exercisable to the extent it was
exercisable as of the Grantee's last date of employment.
<PAGE>
 
If a Grantee's employment is terminated by reason of death, the representative
of his estate or beneficiaries thereof to whom the option has been transferred
shall have the right, during the period ending on the earlier of the date on
which such option would otherwise expire or three months after such termination
of employment, to exercise any then outstanding Non-Qualified Stock Options in
whole or in part. If a Grantee dies without having fully exercised any then
outstanding Non-Qualified Stock Options, the representative of his estate or
beneficiaries thereof to whom the option has been transferred shall have the
right to exercise such options in whole or in part. The number of shares of
Stock in respect of which a Non-Qualified Stock Option may be exercised after a
Grantee's death shall be the number of shares of Stock in respect of which such
option could be exercised as of the Grantee's last date of employment.

        5. Manner of Exercise. Full payment for the shares of Stock purchased
           ------------------
shall be made at the time of any exercise of this Agreement. The purchase price
shall be payable to the Corporation either (i) in cash or by check, bank draft,
or postal or express money order, (ii) by promissory note, (iii) through the
delivery of shares of Class A or Class B Common Stock then owned by the Grantee
having a Fair Market Value on the date of exercise equal to the full purchase
price, provided that the shares so delivered have been owned by the Grantee for
at least six (6) months, or (iv) by a combination of (i), (ii) or (iii) above;
provided, however, that no fractional share shall be accepted by the Corporation
in partial payment of the purchase price of any Stock but the value of any such
fractional interest shall be paid to the Corporation in the manner specified in
(i) above.

Subject to the terms and conditions hereof, the options shall be exercisable by
notice to the Corporation on the form provided by the Corporation, a copy of
which is attached hereto. In the event that the options are being exercised by
any person or persons other than the Grantee, the notice shall be accompanied by
proof, satisfactory to the Corporation, of the right of such person or persons
to exercise any right under this Agreement.

        6. Rights of Grantee. The grant of an option in any year shall give such
           -----------------
Grantee neither any right to similar grants in future years nor any right to be
retained in the employ of the Corporation or any of its subsidiaries, such
employment being terminable to the same extent as if the Plan and this Agreement
were not in effect.

Neither the Grantee nor any other person legally entitled to exercise any rights
under this Agreement shall be entitled to any of the rights or privileges of a
stockholder of the Corporation with respect to any shares which may be issuable
upon any exercise pursuant to this Agreement, unless and until a certificate or
certificates representing such shares shall have been actually issued and
delivered to the Grantee or such person.

        7. Non-Transferability of Option. Except as otherwise provided herein,
           -----------------------------
an option and the rights and privileges conferred hereby may not be transferred,
assigned, pledged or hypothecated in any way, other than by will or the laws of
descent and distribution, and an option shall be exercisable during the
Grantee's lifetime only by the Grantee or his conservator.

        8. Taxes and Withholding. All payments to a Grantee or to his legal
           ---------------------
representative shall be subject to any applicable tax, community property, or
other statutes or regulations of the United States or of any state having
jurisdiction thereof. The Grantee may be required to pay to the Corporation the
amount of any withholding taxes which the Corporation is required to withhold
with respect to a Stock Option or its exercise. In the event that such payment
is not made when due, the Corporation shall have the right to deduct, to the
extent permitted by law, from any payment of any kind otherwise due to such
person all or part of the amount required to be withheld.

        9. Notices. Each notice relating to this Agreement shall be in writing
           -------
and delivered in person or by registered mail to the Corporation at its office,

the Grantee or such other 
<PAGE>
 
person or persons at the Grantee's address specified below or at such other
address as the Grantee or such other person may specify in writing to the
Corporation by a notice delivered in accordance with this paragraph.

        10. Restriction on Shares. The Corporation's obligation to issue or
           ----------------------
deliver any certificate or certificates for shares of Stock under this option,
and the transferability of shares acquired by the exercise of this option, shall
be subject to all of the following conditions:

             be necessary to advisable.

        (c)  Each stock certificate issued pursuant to exercise of this option
             shall bear the following legend:

     4. DURATION OF OFFER. The offer to sell on the terms set forth in this
Agreement is conditioned on Purchaser executing this Agreement and delivering
said executed Agreement to Seller together with the payment called for in
subparagraph (a) of Schedule C (the "Deposit") on or before March 14, 1996. If
this Agreement is not executed and delivered to Seller together with the
required payments by that date, this offer to sell shall terminate.

     5. CLOSING AND AFFIDAVITS. The closing of title ("Closing") shall take
place at the offices of Gregory and Adams, P.C., 190 Old Ridgefield Road,

All real estate taxes, personal property taxes, tax assessments, sewer
assessments, water rents, and other assessments and charges affecting the
Property, Furnishings and Equipment and Personal Property shall be apportioned
as of the date of Closing in accordance with local custom. Should any tax or
charge, tax assessment or rate be undetermined on the date of Closing, the last
determined tax or charge, assessment or rate shall be used for the purpose
of the apportionment and a readjustment shall be made after the tax or charge,
assessment or rate is determined. Purchaser shall pay Seller at the Closing for
the value of any fuel oil, bottled gas or gasoline stored on the Property at the

Closing. The readjustment provisions contained in this Paragraph 6 shall survive
the Closing.

     8. INSURANCE AND RISK OF LOSS. Throughout the period between the date of
this Agreement and the Closing, Seller shall keep the buildings on the Property
insured against loss by fire and other casualty to the extent they are presently
insured as set forth in Schedule G. If during said period any of the buildings
on the Property shall be destroyed or damaged by fire or other casualty
resulting in more than $2,500,000.00 in damage (according to estimate of one
appraiser appointed by agreement of Seller and Purchaser, or if Seller and
Purchaser cannot agree, then by three appraisers, one appointed by Seller, one
by Purchaser, and the third appointed by the first two appraisers so appointed),
Seller shall so notify Purchaser, and Purchaser may elect by giving Seller
written notice, within fifteen (15) business days of said notice, to either: (a)
terminate this Agreement, in which event Seller shall return to Purchaser the
Deposit and any interest accrued thereon together with a certified check or
cashier's check to the order of Purchaser in payment of all reasonable expenses
actually incurred by Purchaser (not to exceed $80,000.00) for: (i) the due
diligence investigation provided for in subparagraphs A, B, D and E of paragraph
10 of this Agreement; and (ii) reasonable legal fees in connection with the
transactions contemplated by this Agreement, and Purchaser shall return to
Seller any and all documents and plans delivered to Purchaser by Seller,
whereupon all rights and liabilities of the parties hereunder shall be at an
end, with the exception of the parties' indemnification obligations as provided
in paragraph 10 of this Agreement or (b) declare this Agreement to remain in
full force and effect and at Closing, Seller shall assign, transfer and set over
to Purchaser all of the right, title and interest of Seller in and to any
insurance proceeds or claims that have been or that may thereafter be made for
such damage, and the Purchase Price shall be reduced by the amount of any
insurance deductible (which reduction to the Purchase Price shall reduce the
cash payable by Purchaser at Closing). If such damage is reasonably estimated by
the appraiser or appraisers to be less than $2,500,000.00, then this Agreement
shall remain in full force and effect and Seller may elect, by written notice
delivered to Purchaser not later than ten (10) business days following the
occurrence of such damage, to: (i) repair such damage to its pre-existing
condition prior to Closing; or (ii) reduce the Purchase Price by an amount
sufficient to effect a repair of such damage to its pre-existing condition.

     9. TITLE. At the Closing, Seller shall convey to Purchaser or its designee
good and marketable fee simple title to the Property, subject only to the
Permitted Encumbrances. It is mutually understood and agreed that no matter
shall be construed to be an encumbrance or defect in title so long as such
matter is not considered an encumbrance or defect under the Standards of Title
of the Connecticut Bar Association as amended or ss. ss.47-33b through 47-33l of
the Connecticut General Statutes, where applicable.

     Purchaser shall have a period of thirty (30) days from the execution of
this Agreement to obtain a commitment for title insurance on the Property (the
"Title Commitment"). Within ten (10) days thereafter, Purchaser's attorney shall
notify Seller's attorney in writing of any exceptions to title which do not
appear as Permitted Encumbrances on Schedule B. Seller shall proceed diligently
and in good faith to cure any defects of title within sixty (60) days of receipt
of such notice at Seller's sole cost and expense. Seller shall be required to
undertake any necessary and reasonable measures and to bring any action or
proceeding

                                       -8-
<PAGE>
 
necessary and reasonable and to incur any reasonable expense necessary to render
the title to the Property marketable at the Closing.

     If Seller is unable to cure such defect within said sixty (60) day period,
Seller shall so advise Purchaser and Purchaser shall have the right to either:
(i) accept such title as Seller can convey, upon the payment of the balance of
the Purchase Price; or (ii) terminate this Agreement. In the event Purchaser
terminates this Agreement pursuant to this paragraph 9, Seller shall return the
Deposit and any interest accrued thereon to Purchaser together with a certified
check or cashier's check to the order of Purchaser in payment of all reasonable
expenses actually incurred by Purchaser (not to exceed $80,000.00) for: (i) the
due diligence investigation provided for in subparagraphs A, B, D and E of
paragraph 10 of this Agreement; and (ii) reasonable legal fees in connection
with the transactions contemplated by this Agreement, and Purchaser shall return
to Seller any and all documents and plans delivered to Purchaser by Seller,
whereupon all rights and liabilities of the parties hereunder shall be at an
end, with the exception of the parties' indemnification obligations as provided
in paragraph 10 of this Agreement.

     No later than five (5) business days prior to the Closing, Purchaser shall
cause an update of the Title Commitment to be prepared. As a condition of
Closing, the updated Title Commitment shall reflect no change since the date of
the original Title Commitment in the state or quality of title to the Property,
except such changes as have been requested by Purchaser, which shall thereafter
be deemed a Permitted Encumbrance. If the updated Title Commitment should
disclose that the Property is affected by an outstanding exception to title
which is not a Permitted Encumbrance and is not disclosed in the original Title
Commitment and is not accepted by Purchaser as an additional Permitted
Encumbrance, Purchaser shall notify Seller in writing of the outstanding
exception and Seller shall have sixty (60) days from the date that it receives
notice from Purchaser of said exception to remove the objection to title or
otherwise reasonably satisfy Purchaser with respect thereto and the Closing
hereunder shall be adjourned until the date which is twenty (20) days following
the earlier of the expiration of Seller's sixty (60) day cure period or the date
that Seller satisfies Purchaser that the objection to title has been removed. If
after any applicable adjournment Seller shall be unable to convey title to the
Property in accordance with the provisions of this Agreement, then Purchaser
shall have the right to either: (i) accept such title as Seller can convey, upon
the payment of the balance of the Purchase Price; or (ii) terminate this
Agreement. In the event Purchaser terminates this Agreement pursuant to this
paragraph 9, Seller shall return the Deposit and any interest accrued thereon to
Purchaser together with a certified check or cashier's check to the order of
Purchaser in payment of all reasonable expenses actually incurred by Purchaser
(not to exceed $80,000.00) for: (i) the due diligence investigation provided for
in subparagraphs A, B, D and E of paragraph 10 of this Agreement; and (ii)
reasonable legal fees in connection with the transactions contemplated by this
Agreement, and Purchaser shall return to Seller any and all documents and plans
delivered to Purchaser by Seller, whereupon all rights and liabilities of the
parties hereunder shall be at an end, with the exception of the parties'
indemnification obligations as provided in paragraph 10 of this Agreement.

                                       -9-

     Purchaser shall bear all costs of any title insurance insuring Purchaser's
interest in the Property.

     10. DUE DILIGENCE INVESTIGATION. Purchaser acknowledges and agrees that the
Property is to be sold and conveyed to, and purchased and accepted by, Purchaser
in its present condition, "as is" and with all faults. Purchaser further
acknowledges and agrees that Purchaser is not relying on, and Seller has not
made and will not make, any representation or warranty, express or implied, with
respect to the Property or its condition (environmental and otherwise and its
potential for further development), present state of repair, compliance with
laws and regulations (environmental and otherwise) or its potential for further
development, merchantability or suitability for any purpose except as provided
in this Agreement, and that Seller shall have no further liability with respect
to any of the foregoing.

     Between the date of execution of this Agreement by both parties and May 25,
1996 (the "Due Diligence Period") Purchaser shall have the opportunity to
inspect the Property, observe its physical characteristics and existing
condition, and conduct such investigations, tests and studies on and of the
Property as Purchaser, in its sole discretion, deems necessary or appropriate to
satisfy itself as to its condition, environmental and otherwise, and its
potential for further development.

     Seller acknowledges that Purchaser's due diligence may, in Purchaser's
sole discretion, include, but not be limited to:

     A.   building structural, mechanical and other engineering inspections of
          the Improvements,

     H.   traffic studies and investigations relative to the feasibility of
          increasing the traffic to the Property, and

     I.   investigations relative to increasing water usage to and sanitary
          waste disposal from the Property in connection with a contemplated
          expansion of building area on the Property.

     At Purchaser's reasonable request during the Due Diligence Period, Seller
shall use reasonable efforts to respond to requests to provide or make available
to Purchaser documentation and information in Seller's (or Richardson-Vicks
Inc.'s) or Cushman & Wakefield of Connecticut, Inc.'s, in its capacity as the
manager of the Property, possession which pertains to Purchaser's due diligence
investigations relating to the Property.

     Purchaser acknowledges that Seller has provided to Purchaser a copy of
Seller's "ASTM Phase I Environmental Site Assessment" (the "Phase I") pertaining
to the Property dated June, 1995 and "Phase II Environmental Site Assessment"
(the "Phase II") pertaining to the Property, dated February, 1996, prepared by
Geraghty & Miller. Purchaser agrees that it has not and will not rely on such
reports to any degree, and will not seek to hold Seller or its consultant
responsible for anything stated or not stated in such reports, and Seller does
not represent or warrant that such reports are comprehensive or accurate.
Notwithstanding the foregoing, at the request of Purchaser, Seller shall request
Geraghty & Miller to issue to Purchaser a letter advising Purchaser that it may
rely on the Phase I and the Phase II to the extent and subject to the conditions
set forth in said letter, it being the agreement of the parties that Purchaser
shall be solely responsible for any costs or expenses associated with the
issuance of the letter.

     Upon reasonable oral or written notice, Purchaser, its employees, agents
and contractors, may, at their own risk and expense, enter the Property, from
time to time, during the Due Diligence Period for purposes of conducting
Purchaser's due diligence investigations and studies. Purchaser shall indemnify
and hold Seller, its affiliates and all of their respective directors, officers,
employees, contractors and agents harmless from any claims, damages, loss,
judgments and expenses of any kind, including but not limited to reasonable
attorneys' fees, for damage to the property or person (including death) of
Seller, Purchaser, their respective affiliates, their respective directors,
officers, employees, contractors, agents and any other third party whomsoever
arising out of or in connection with Purchaser's or Purchaser's directors',
officers', employees', agents' or contractors' entry onto the Property,
provided, however, that Seller shall remain fully liable for and shall indemnify
and hold Purchaser, its affiliates and all of their respective officers,
directors, employees, agents or contractors harmless from and against, any and
all liability, claims, loss and damage, including, but not limited to,
reasonable attorney fees, arising out of any negligence or misconduct of Seller
or its affiliates or their respective officers, directors, employees, agents or
contractors. In the event such entry by Purchaser or its affiliates or


                                      -11-
<PAGE>
 
their respective directors, officers, employees, contractors or agents results
in any property damage to the Property, including, but not limited to, lost
opportunity and other damages relating to any delay in Seller's ability or
Seller's inability to promptly market the Property and this Agreement fails to
be consummated for any reason, Purchaser immediately shall restore the Property
to its pre-existing condition reasonable wear and tear and damage due to
casualty not caused by Purchaser's activities excepted (or to the extent
reasonably practicable with respect to any invasive environmental testing) or
reimburse Seller for the reasonable cost of repair of the damage so caused.

     Purchaser shall, at Purchaser's sole expense, keep and maintain a policy of
comprehensive public liability insurance which shall include contractual
liability coverage of the indemnification set forth in this paragraph 10. This
insurance policy shall name Seller as an additional insured and afford
protection in limits of not less than $2,000,000.00 for bodily injury or death
in any one accident, and not less than $1,000,000.00 for property damage on an
"occurrence" not "claims made" basis and shall expire no earlier than one (1}
year from the date hereof. All insurance shall be effected under standard form
policies, issued by insurers of recognized responsibility authorized to do
business in the State of Connecticut and having A.M. Best's rating of "A" or
better. Purchaser shall deliver a copy of the policy to Seller prior to the
commencement of the inspections.


     Except as otherwise provided in this Agreement, any costs or expenses
incurred by Purchaser in connection with the inspection of the Property shall be
the sole responsibility of Purchaser.

     Any objection(s) Purchaser may have to the condition of the Property as a
result of Purchaser's due diligence inspections, tests and studies (including
without limitation objections as to any hazardous substances, hazardous waste,
hazardous materials or other contamination in, at, on, under or related to the
Property) shall be noticed to Seller by the expiration of the Due Diligence
Period or thereafter shall be deemed waived for all purposes. The parties hereby
agree that Seller, in its sole discretion, may elect not to remedy or resolve
the objection. Seller shall provide Purchaser with written notice of its
election within ten (10) days of receipt from Purchaser of notice of
objection(s). In the event Seller elects to remedy the defect giving rise to the
objection(s), Seller shall have sixty (60) days from the date that it notifies
Purchaser of said election to remedy the defect or otherwise reasonably satisfy
Purchaser with respect thereto and the Closing hereunder shall be adjourned
until the date which is twenty (20) days following the earlier of the expiration
of Seller's sixty (60) day cure period or the date that Seller satisfies
Purchaser that the objection has been remedied. In the event Seller: (i) fails
to deliver said notice within said ten (10) day period or (ii) elects not to
remedy the objection(s) or (iii) fails to remedy or resolve the objection(s) to
Purchaser's satisfaction, then Purchaser in its sole discretion, may terminate
this Agreement. In the event Purchaser terminates this Agreement pursuant to
this paragraph 10, Seller shall return the Deposit and any interest accrued
thereon to Purchaser together with a certified check or cashier's check to the
order of Purchaser in payment of all reasonable expenses actually incurred by
Purchaser (not to exceed $80,000.00) for: (i) the


                                      -12-
<PAGE>
 
due diligence investigation provided for in subparagraphs A, B, D and E of this
paragraph 10; and (ii) reasonable legal fees in connection with the transactions
contemplated by this Agreement, and Purchaser shall return to Seller any and all
documents and plans delivered to Purchaser by Seller, whereupon all rights and
liabilities of the parties hereunder shall be at an end, with the exception of
the parties' indemnification obligations as provided in this paragraph 10.
Notwithstanding the provisions of this paragraph 10 to the contrary, in the
event Purchaser's termination is not based upon the due diligence investigation
provided for in subparagraphs A, B, D and E of this paragraph 10, Seller shall
return the Deposit and any interest accrued thereon to Purchaser and Purchaser
shall return to Seller any and all documents and plans delivered to Purchaser by
Seller, whereupon all rights and liabilities of the parties hereunder shall be
at an end, with the exception of the parties' indemnification obligations as
provided in this paragraph 10.

     The provisions of this paragraph 10 will survive the closing as necessary
to effectuate their purpose and will not merge in any deed or conveyance.

     As a condition precedent to Purchaser's obligation to close herein, Seller
agrees that it shall demolish and remove the residential structure (formerly a
farmhouse) (hereinafter the "Farmhouse") located on the Property and shall
dispose of the Farmhouse structure and all items and debris located within and
about the Farmhouse to the extent required by and in full compliance with all
applicable laws, including, but not limited to all environmental laws (the
"Demolition and Removals"). Any costs or expenses incurred by Seller in
connection with the Demolition and Removal of the Farmhouse to the extent
required by and in full compliance with all applicable laws, shall be the sole
responsibility of Seller. Seller shall make reasonable efforts to complete the
Demolition and Removal on or before May 4, 1996. Upon reasonable notice to
Seller, Purchaser, at its risk, may be present at the Property during the
Demolition and Removal and may conduct, at its sole cost and expense, such due
diligence investigations with respect to the Demolition and Removal as
reasonably may be conducted under the circumstances. In the event that the
Demolition and Removal is not completed by Seller on or before May 4, 1996,
Purchaser shall make its reasonable efforts to complete its due diligence with
respect to the Demolition and Removal prior to May 25, 1996. If, despite its
reasonable efforts, Purchaser does not complete its due diligence with respect
to the Demolition and Removal prior to May 25, 1996, Purchaser may elect, upon
written notice to Seller, to extend the Due Diligence Period with respect to the
Demolition and Removal one (1) day for each day beyond May 4, 1996 that the
Demolition and Removal was not completed by Seller.

     11. DEFAULT.

     A. Default by Purchaser. If, through no fault of Seller, Purchaser defaults
in its obligation to close title as required by this Agreement, then providing
Seller is not in default of any of its obligations under this Agreement, Seller
by written notice of default to Purchaser, may terminate this Agreement and
immediately may demand the Deposit from the Trustee (as identified in Schedule
C) and thereafter, as Seller's sole and exclusive remedy


                                      -13-
<PAGE>
 
therefor, may retain the Deposit and any interest accrued thereon as agreed upon
Seller's liquidated damages. The parties recognize that Purchaser's default will
cause substantial injury to Seller and agree that the amount represented by the
Deposit and any interest accrued thereon shall be a fair and reasonable
approximation of the damages Seller will suffer in the event of Purchaser's
default. It is understood and agreed that upon Purchaser's default and Seller's
retention of the Deposit and any interest accrued thereon, this Agreement will
terminate and the parties will have no further liability or obligation hereunder
except for: (i) Purchaser's obligation to return to Seller all documents and
plans delivered to Purchaser by Seller; and (ii) the indemnification obligations
of the parties as provided in paragraph 10 of this Agreement. Purchaser's and
Seller's obligation to indemnify the Trustee and hold it harmless (as provided
in Schedule C) shall survive any termination of this Agreement. Payment of said
liquidated damages shall be Seller's sole remedy and it shall have no right
against Purchaser for specific performance or monetary damages.

     B. Default by Seller. If, through no fault of Purchaser, Seller defaults in
the performance of its obligations hereunder, then provided Purchaser is not in
default of any of its obligations under this Agreement, Purchaser by written
notice of default to Seller, may elect to terminate this Agreement and
immediately may demand the return of the Deposit from the Trustee and any
interest accrued thereon together with a certified check or cashier's check to
order of Purchaser in payment of all reasonable expenses actually incurred by
Purchaser for: (i) the due diligence investigations provided for in
subparagraphs A, B. C, D, E, F, G, H and I of paragraph 10 of this Agreement;
and (ii) reasonable legal fees in connection with the transactions contemplated
by this Agreement. The parties recognize that Seller's default will cause
substantial injury to Purchaser and agree that the amount represented by the
interest accrued on the Deposit, and the liquidated damages as calculated in
subparagraphs 11.B.(i) and (ii) above shall be a fair and reasonable
approximation of the damages Purchaser will suffer in the event of Seller's
default. It is understood and agreed upon that upon Seller's default and
Purchaser's receipt of the Deposit together with any interest accrued thereon,
and a certified check or cashier's check to the order of Purchaser in the amount
of said liquidated damages due Purchaser, this Agreement will terminate and the
parties will have no further liability or obligation hereunder except for: (i)
Purchaser's obligation to return to Seller all documents and plans delivered to
Purchaser by Seller; and (ii) the indemnification obligations of the parties as
provided in paragraph 10 of this Agreement. Seller's and Purchaser's obligation
to indemnify the Trustee and hold it harmless (as provided in Schedule C) shall
survive any such termination of this Agreement.

     As an alternative to Purchaser's election to terminate this Agreement by
reason of Seller's default, Purchaser shall have the right to: (i) specifically
enforce this Agreement and Seller's obligations hereunder; and (ii) seek actual
damages, including, but not limited to, reasonable legal fees incurred by
Purchaser by reason of Seller's default (excluding expenses incurred by
Purchaser for the due diligence investigations provided for in subparagraphs A,
B, C, D, E, F, G, H and I of paragraph 10 of this Agreement and legal fees in
connection with the transactions contemplated by this Agreement prior to
Seller's default).


                                      -14-
<PAGE>
 
     12. ASSIGNMENT. Purchaser may not assign this Agreement or any right, title
or interest therein, except to any affiliated or subsidiary entity, without
Seller's prior written consent, which shall not be unreasonably delayed or
withheld. Upon any effective assignment of Purchaser's rights hereunder,
Purchaser and Purchaser's assignee shall become and be jointly and severally
liable hereunder.

     13. POSSESSION. Simultaneously with the Closing, Seller shall deliver
exclusive possession of the Property to Purchaser.

     14. BROKERS. The parties hereto recognize Rostenberg-Doern Company, Inc.
and Cushman & Wakefield of Connecticut, Inc. as the sole brokers who negotiated
the sale of the Property, and Seller shall pay said brokers a commission in
accordance with a listing agreement between Seller and Rostenberg-Doern Company,
Inc. The parties enter into this Agreement in reliance on the representation of
each party, hereby made, that no other broker or agent brought the Property to
Purchaser's attention or was in any way a procuring cause of this sale and
purchase. In the event any other broker shall make a claim against either of the
parties (the "Claimant") based upon dealing with the other party, such other
party shall indemnify the Claimant from and hold it harmless against any and all
damages or reasonable attorney's fees the Claimant may pay as a result of such
claim (it being the agreement of the parties that the Claimant will not settle
or compromise any claim without the other party's prior written consent). Seller
represents that no broker other than Rostenberg-Doern has a listing agreement
for the Property. The representations contained in this Paragraph 14 shall
survive the Closing.

     15. ENTIRE AGREEMENT. This Agreement (including the Schedules and Exhibits
referred to in the body of this Agreement and attached hereto) constitutes the
entire agreement between the parties and they hereby acknowledge that neither
relies on any express or implied representations, warranties, conditions or
understandings except those expressly set forth herein.

     16. LANGUAGE. Wherever herein used, the singular number shall include the
plural, the plural the singuIar, and the use of any gender shall be applicable
to all genders.

     17. BINDING AGREEMENT. This Agreement shall be binding upon, and inure to
the benefit of the successors and permitted assigns of Seller and Purchaser.

statements is true and correct as of the date of this Agreement and shall be
true and correct on the date of the Closing:

          encumbrances, or restrictions, except for the Permitted Encumbrances.

          or


                                      -16-
<PAGE>
 
          requirements affecting the Property, with the exception of the 550
          gallon underground diesel fuel tank located on the Property (which
          tank shall be brought into full compliance with all applicable laws by
          Seller, at its sole cost and expense, prior to Closing), nor has
          Seller ever received any notice concerning such noncompliance, the
          terms of which have not been complied with, and no breach presently
          exists under any public or private covenant, condition, restriction,
          right-of-way or easement which affects the use and/or access to the
          Property or any portion thereof and Seller will promptly notify
          Purchaser of the receipt of any notice of any such violations received

          or administrative proceeding pending or threatened against, or
          relating to the Property. 

     E.   Seller has not filed a voluntary petition in bankruptcy or has not
          been adjudicated a bankrupt or insolvent, or filed any petition or
          answer seeking any reorganization, liquidation, dissolution or similar
          relief under any federal bankruptcy, insolvency, or other law relating
          to relief for debtors, or sought or consented to or acquiesced in the
          appointment of any trustee, receiver, conservator or liquidator of all
          or any substantial part of its properties or its interests in the
          Property. No court of competent jurisdiction has entered an order,
          judgment, or decree approving a petition filed against Seller seeking
          any reorganization, arrangement, composition, readjustment,
          liquidation, dissolution or similar relief under any federal

          Seller nor Richardson-Vicks Inc. has received any notice from or on
          behalf of any of its insurance carriers regarding any dangerous,
          illegal, or other condition on the Property requiring corrective
          action or indicating that the insurance rates for any part of the
          Property will be increased, or that such insurance carriers will not
          renew such existing policies, or that alterations to all or any part
          of the Property will be required as a condition to any such renewal or
          as a requirement of avoiding any such increase in premiums, with the
          exception that Richardson-Vicks Inc. may have been advised by its
          insurance carrier to install a sprinkler system in the Farmhouse.

          public improvements which would result in any special assessments
          being levied against the Property or any portion thereof and no
          special assessments are currently levied against the Property or any
          portion thereof, except as may be disclosed on Schedule B hereto.

          Agreement in accordance with its terms and this Agreement has been
          duly authorized and executed by Seller and is enforceable against

          by Seller to Purchaser at the Closing will be duly executed by Seller
          and enforceable against Seller in accordance with their terms and no
          consent, license, approval or authorization of, or filing,

          in connection with the execution, delivery or performance by Seller

          Property, except for property taxes assessed but not due and payable
          at the time of Closing.

          extended coverage risks, business interruption, rent loss and
          liability to be kept in full force and effect through and including

                                  ARTICLE XIII

                                  MISCELLANEOUS

          13. l Stop-Loss Coverage. Guardian shall have the right to provide
Contractholders with stop-loss insurance or reinsurance with respect to HMO
Plans that are Managed Care Contracts subject to this Agreement. Guardian shall
have the right to bid on stop-loss reinsurance protection for all other business
of PHS. Nothing herein shall require PHS to reinsure HMO Plans that are not
Managed Care Contracts with Guardian. In addition, Guardian acknowledges that
PHS has certain existing arrangements, and may enter into additional
arrangements in the future, for stop-loss reinsurance coverage for HMO Plans
that are not Managed Care Contracts which shall remain in effect regardless of
this Agreement.

          13.2 Misunderstandings and Oversights. If any delay, omission, error
or failure to perform any act required by this Agreement is unintentional and
caused by misunderstanding or oversight, PHS and Guardian will adjust the
situation to what it would have been had the misunderstanding or oversight not
occurred. The party that first discovers such oversight or incorrect act as a
result of the misunderstanding will notify the other party in writing promptly
upon discovery of the misunderstanding or oversight. The parties shall act to
correct the error, omission or oversight within thirty (30) days of notification
of the problem. This Section 13.2


                                       33
<PAGE>
 
shall not be construed as a waiver by either party of its right to enforce
strictly the terms of this Agreement.

     13.3 Non-Solicitation. (a) During the term of this Agreement, neither
Guardian nor any entity under Guardian's control shall contact, solicit or
contract for services with any PHS Network health care provider then under
contract with PHS. Nothing in this Agreement shall preclude PHCS from
contracting with any PHS Network health care provider.

     (b) During the term of this Agreement, neither party shall knowingly
solicit for employment an employee of the other party who has been engaged in
activities covered by this Agreement, without written consent of the other
party.

     13.4 Regulatory Approval. Performance of the obligations of either party
under this Agreement shall be subject to the receipt of necessary regulatory
approvals under the laws, regulations and practices of regulatory authorities in
New York and Connecticut. PHS and Guardian shall cooperate in attempting to
obtain expeditiously any necessary regulatory approvals from regulatory
authorities. Each party will bear its own expenses in obtaining such approvals.

     13.5 Audits. Each party shall have the right, upon reasonable notice to the
other party, and at the requesting party's expense, to audit the books and
records of the other party


                                       34
<PAGE>
 
relating to receipts, enrollment, service standards and other matters relating
to this Agreement during regular business hours at the premises of the audited
party where such records are normally maintained. The audited party shall
reasonably cooperate in any such audit.

     13.6 Headings and Schedules. Headings used herein are not part of this
Agreement. Any Schedules or Exhibits attached hereto are part of this Agreement.

     13.7 Compliance with Applicable Laws and Regulations. It is the intention
of the parties that this Agreement comply with all existing applicable laws and
regulations, as from time to time are in effect, so that the Agreement remains
in full force. Each of the parties agrees to comply with all laws, ordinances,
rules, regulations and orders of regulatory bodies applicable to the
transactions contemplated by this Agreement, including those relating to
maintenance of appropriate licenses and the appointment of agents and payment of
commissions. Either party shall promptly notify the other party of any
complaint, inquiry or lawsuit by any regulatory authority relating to the
Managed Care Contracts or to this Agreement.

     13.8 Successors and Assigns: Binding Effect. Except as otherwise provided
herein and in the HMO Reinsurance Agreement, this Agreement cannot be assigned
by PHS or Guardian without the prior written approval of the other party. The
provisions of this


                                       35
<PAGE>
 
Agreement shall be binding upon and inure to the benefit of and be enforceable
by the parties hereto and their respective permitted successors and assigns.

     13.9 Counterparts. This Agreement may be executed simultaneously in any
number of counterparts, each of which will be deemed an original, but all of
which will constitute one and the same agreement.

     13.10 Entire Agreement: Amendment. This Agreement and the Reinsurance
Agreement constitute the entire agreement between the parties with respect to
the Managed Care Contracts and Ancillary Products, and supersede any previous
written or oral agreements. This Agreement shall be amended only by written
agreement signed by a duly authorized officer of each of PHS and Guardian, and
any change to this Agreement shall be null and void unless made by such written
agreement; provided, however, that where, under insurance, health or other
applicable laws or regulations, the approval of any such amendment to this
Agreement by one or more federal, state or local governmental or regulatory
authorities is required, the amendment shall not take effect unless and until
all such necessary approvals have been obtained and received by both PHS and
Guardian. In the event that any such approval is required, PHS and Guardian
shall each take all necessary actions in order to obtain such approval.


                                       36

     13.11 Waivers. The waiver by either of the parties of the other party's
prompt and complete performance, or breach or violation, of any provisions of
this Agreement and related documents shall not operate or be construed as a
waiver of any subsequent breach or violation, and the waiver by any of the
parties to exercise any right or remedy which it may possess hereunder shall not
operate or be construed as a bar to the exercise of such right or remedy by such
party upon the occurrence of any subsequent breach or violation.

     13.12 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Connecticut, without giving effect to
the principles of conflicts of laws thereof.

     13.13 Severability. In the event any section or provision of this Agreement
or related documents is found to be void and unenforceable by a court of
competent jurisdiction, the remaining sections and provisions of this Agreement
or related documents shall nevertheless be binding upon the parties with the
same force and effect as though the void or unenforceable part had not been
severed or deleted.

                                  MISCELLANEOUS

     13.1 Stop-Loss Coverage. Guardian shall have the right to provide
Contractholders with stop-loss insurance or reinsurance with respect to HMO
Plans that are Managed Care Contracts subject to this Agreement. Guardian shall
have the right to bid on stop-loss reinsurance protection for all other business
of PHS. Nothing herein shall require PHS to reinsure HMO Plans that are not
Managed Care Contracts with Guardian. In addition, Guardian acknowledges that
PHS has certain existing arrangements, and may enter into

                                       35
<PAGE>
 
additional arrangements in the future, for stop-loss reinsurance coverage for
HMO Plans that are not Managed Care Contracts which shall remain in effect
regardless of this Agreement.

     13.2 Misunderstandings and Oversights. If any delay, omission, error or
failure to perform any act required by this Agreement is unintentional and
caused by misunderstanding or oversight, PHS and Guardian will adjust the
situation to what it would have been had the misunderstanding or oversight not
occurred. The party that first discovers such oversight or incorrect act as a
result of the misunderstanding will notify the other party in writing promptly
upon discovery of the misunderstanding or oversight. The parties shall act to
correct the error, omission or oversight within thirty (30) days of notification
of the problem. This Section 13.2 shall not be construed as a waiver by either
party of its right to enforce strictly the terms of this Agreement.

     13.3 Non-Solicitation. (a) During the term of this Agreement, neither
Guardian nor any entity under Guardian's control shall contact, solicit or
contract for services with any PHS Network health care provider then under
contract with PHS. Nothing in this Agreement shall preclude PHCS from
contracting with any PHS Network health care provider.

     (b) During the term of this Agreement, neither party shall knowingly
solicit for employment an employee of the other party who has been engaged in
activities covered by this Agreement, without written consent of the other
party.

     13.4 Regulatory Approval. Performance of the obligations of either party
under this Agreement shall be subject to the receipt of necessary regulatory
approvals under the laws, regulations and practices of regulatory authorities in
New York. PHS and Guardian shall cooperate in attempting to obtain expeditiously
any necessary regulatory approvals from regulatory authorities. Each party will
bear its own expenses in obtaining such approvals.

     13.5 Audits. Each party shall have the right, upon reasonable notice to the
other party, and at the requesting party's expense, to audit the books and
records of the other party relating to receipts, enrollment, service standards
and other matters relating to this Agreement during regular business hours at
the premises of the audited party where such records are normally maintained.
The audited party shall reasonably cooperate in any such audit.

     13.6 Headings and Schedules. Headings used herein are not part of this
Agreement. Any Schedules or Exhibits attached hereto are part of this Agreement.

     13.7 Compliance with Applicable Laws and Regulations. It is the intention
of the parties that this Agreement comply with all existing applicable laws and
regulations, as from time to time are in effect, so that the Agreement remains
in full force. Each of the parties agrees to comply with all laws, ordinances,
rules, regulations and orders of regulatory bodies applicable to the
transactions contemplated by this Agreement, including those relating to

                                       37
<PAGE>
 
maintenance of appropriate licenses and the appointment of agents and payment of
commissions. Either party shall promptly notify the other party of any
complaint, inquiry or lawsuit by any regulatory authority relating to the
Managed Care Contracts or to this Agreement.

     13.8 Successors and Assigns: Binding Effect. Except as otherwise provided
herein and in the HMO and Indemnity Reinsurance Agreements this Agreement cannot
be assigned by PHS or Guardian without the prior written approval of the other
party. The provisions of this Agreement shall be binding upon and inure to the
benefit of and be enforceable by the parties hereto and their respective
permitted successors and assigns.

     13.9 Counterparts. This Agreement may be executed simultaneously in any
number of counterparts, each of which will be deemed an original, but all of
which will constitute one and the same agreement.

     13.10 Entire Agreement: Amendment. This Agreement and the Reinsurance
Agreements constitute the entire agreement between the parties with respect to
the Managed Care Contracts and Ancillary Products, and supersede any previous
written or oral agreements. This Agreement shall be amended only by written
agreement signed by a duly authorized officer of each of PHS and Guardian, and
any change to this Agreement shall be null and void unless made by such written
agreement; provided, however, that where, under insurance,

                                       38
<PAGE>
 
health or other applicable laws or regulations, the approval of any such
amendment to this Agreement by one or more federal, state or local governmental
or regulatory authorities is required, the amendment shall not take effect
unless and until all such necessary approvals have been obtained and received by
both PHS and Guardian. In the event that any such approval is required, PHS and
Guardian shall each take all necessary actions in order to obtain such approval.

     13.11 Waivers. The waiver by either of the parties of the other party's
prompt and complete performance, or breach or violation, of any provisions of
this Agreement and related documents shall not operate or be construed as a
waiver of any subsequent breach or violation, and the waiver by any of the
parties to exercise any right or remedy which it may possess hereunder shall not
operate or be construed as a bar to the exercise of such right or remedy by such
party upon the occurrence of any subsequent breach or violation.

     13.12 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New York, without giving effect to the
principles of conflicts of laws thereof.

     13.13 Severability. In the event any section or provision of this
Agreement or related documents is found to be void and unenforceable by a court
of competent jurisdiction, the remaining sections and provisions of this
Agreement or related documents shall nevertheless be

                                       39
<PAGE>
 
binding upon the parties with the same force and effect as though the void or
unenforceable part had not been severed or deleted.

                                   ARBITRATION

     12.1 Appointment of Arbitrators. In the event of any disputes or
differences arising hereafter between the parties with reference to any
transaction under or relating in any way to this Agreement, as to which
agreement between the parties hereto cannot be reached, the dispute or
difference shall be resolved by arbitration. Three arbitrators shall decide any
dispute or difference. The arbitrators must be disinterested officers or retired
officers of life and health insurance or health maintenance organizations other
than the two parties to this Agreement or their affiliates. Each of the parties
agrees to appoint one of the arbitrators with the third, to be chosen by the two
appointed arbitrators. In the event that either party should fail to choose an
arbitrator within thirty (30) calendar days following a written request by the
other party to do so, the requesting party may choose a second arbitrator before
entering upon arbitration. In the event that the two arbitrators shall not be
able to agree on the choice of the third arbitrator within twenty (20) calendar
days following their appointment, each arbitrator shall nominate five (5)
candidates within ten (10) calendar days thereafter, four (4) of whom the other
party shall decline, and the third arbitrator shall be chosen by the President
of the American Arbitration Association or his designee. Should the chosen third
arbitrator so selected decline to serve, the candidate who was not chosen by the
President shall be appointed. This process shall continue until a candidate has
agreed to serve.


                                       34

     12.2 Decision. The arbitrators shall consider customary and standard
practices in the health insurance and managed care business. They shall decide
by a majority vote of the arbitrators. There shall be no appeal from their
written decision. Judgment may be entered on the decision of the arbitrators by
any court having jurisdiction. If, in the opinion of the arbitrators, a dispute
cannot be otherwise resolved, this Agreement shall be terminated in accordance
with Section 10.5 hereof.

     12.3 Expenses of Arbitration. Each party shall bear the expense of its own
arbitrator (whether selected by that party, or by the other party pursuant to
the procedures set out in Section 12.1) and related outside attorneys' fees, and
shall jointly and equally bear with the other party the expenses of the third
arbitrator.

     12.4 Applicable Law. Any arbitration instituted pursuant to this Article
shall be held in New Jersey and the laws of the State of New Jersey and, to the
extent applicable, the Federal Arbitration Act, shall govern the interpretation
and application of this Agreement.

     12.5 Survival of Article. This Article shall survive termination of this
Agreement.

                                 MISCELLANEOUS

     13.1 Stop-Loss Coverage. Guardian shall have the right to provide
Contractholders with stop-loss insurance or reinsurance with respect to HMO
Plans that are Managed Care Contracts subject to this Agreement. Guardian shall
have the right to bid on stop-loss reinsurance protection for all other business
of PHS. Nothing herein shall require PHS to reinsure HMO Plans that are not
Managed Care Contracts with Guardian. In addition, Guardian acknowledges that
PHS has certain existing arrangements, and may enter into additional
arrangements in the future, for stop-loss reinsurance coverage for HMO Plans
that are not Managed Care Contracts which shall remain in effect regardless of
this Agreement.

     13.2 Misunderstandings and Oversights. If any delay, omission, error or
failure to perform any act required by this Agreement is unintentional and
caused by misunderstanding or oversight, PHS and Guardian will adjust the
situation to what it would have been had the misunderstanding or oversight not
occurred. The party that first discovers such oversight or incorrect act as a
result of the misunderstanding will notify the other party in writing promptly
upon discovery of the misunderstanding or oversight. The parties shall act to
correct the error, omission or oversight within thirty (30) days of notification
of the problem. This Section 13.2 shall not be construed as a waiver by either
party of its right to enforce strictly the terms of this Agreement.


                                       36
<PAGE>
 
     13.3 Non-Solicitation. (a) During the term of this Agreement, neither
Guardian nor any entity under Guardian's control shall contact, solicit or
contract for services with any PHS Network health care provider then under
contract with PHS. Nothing in this Agreement shall preclude PHCS from
contracting with any PHS Network health care provider.

     (b) During the term of this Agreement, neither party shall knowingly
solicit for employment an employee of the other party who has been engaged in
activities covered by this Agreement, without written consent of the other
party.

     13.4 Regulatory Approval. Performance of the obligations of either party
under this Agreement shall be subject to the receipt of necessary regulatory
approvals under the laws, regulations and practices of regulatory authorities in
New York and New Jersey. PHS and Guardian shall cooperate in attempting to
obtain expeditiously any necessary regulatory approvals from regulatory
authorities. Each party will bear its own expenses in obtaining such approvals.

     13.5 Audits. Each party shall have the right, upon reasonable notice to the
other party, and at the requesting party's expense, to audit the books and
records of the other party relating to receipts, enrollment, service standards
and other matters relating to this Agreement


                                       37
<PAGE>
 
during regular business hours at the premises of the audited party where such
records are normally maintained. The audited party shall reasonably cooperate in
any such audit.

     13.6 Headings and Schedules. Headings used herein are not part of this
Agreement. Any Schedules or Exhibits attached hereto are part of this Agreement.

     13.7 Compliance with Applicable Laws and Regulations. It is the intention
of the parties that this Agreement comply with all existing applicable laws and
regulations, as from time to time are in effect, so that the Agreement remains
in full force. Each of the parties agrees to comply with all laws; ordinances,
rules, regulations and orders of regulatory bodies applicable to the
transactions contemplated by this Agreement, including those relating to
maintenance of appropriate licenses and the appointment of agents and payment of
commissions. Either party shall promptly notify the other party of any
complaint, inquiry or lawsuit by any regulatory authority relating to the
Managed Care Contracts or to this Agreement.

     13.8 Successors and Assigns: Binding Effect. Except as otherwise provided
herein and in the HMO Reinsurance Agreement; this Agreement cannot be assigned
by PHS or Guardian without the prior written approval of the other party. The
provisions of this Agreement shall be binding upon and inure to the benefit of
and be enforceable by the parties hereto and their respective permitted
successors and assigns.

     13.9 Counterparts. This Agreement may be executed simultaneously in any
number of counterparts, each of which will be deemed an original; but all of
which will constitute one and the same agreement.

     13.10 Entire Agreement: Amendment. This Agreement and the Reinsurance
Agreement constitute the entire agreement between the parties with respect to
the Managed Care Contracts and Ancillary Products, and supersede any previous
written or oral agreements. This Agreement shall be amended only by written
agreement signed by a duly authorized officer of each of PHS and Guardian, and
any change to this Agreement shall be null and void unless made by such written
agreement; provided, however, that where, under insurance, health or other
applicable laws or regulations, the approval of any such amendment to this
Agreement by one or more federal, state or local governmental or regulatory
authorities is required, the amendment shall not take effect unless and until
all such necessary approvals have been obtained and received by both PHS and
Guardian. In the event that any such approval is required, PHS and Guardian
shall each take all necessary actions in order to obtain such approval.

     13.11 Waivers. The waiver by either of the parties of the other party's
prompt and complete performance, or breach or violation, of any provisions of
this Agreement and related documents shall not operate or be construed as a
waiver of any subsequent breach or violation,


                                       39
<PAGE>
 
and the waiver by any of the parties to exercise any right or remedy which it
may possess hereunder shall not operate or be construed as a bar to the exercise
of such right or remedy by such party upon the occurrence of any subsequent
breach or violation.

     13.12 Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of New Jersey, without giving effect to
the principles of conflicts of laws thereof.

     13.13 Severability. In the event any section or provision of this Agreement
or related documents is found to be void and unenforceable by a court of
competent jurisdiction, the remaining sections and provisions of this Agreement
or related documents shall nevertheless be binding upon the parties with the
same force and effect as though the void or unenforceable part had not been
severed or deleted.

dated December 2, 1994) (the "Marketing and Services Agreement").

     3.2 Non-Solicitation. (a) During the term of this Agreement, the Reinsurer
shall not contact, solicit or contract for services with any health care

                                        8
<PAGE>
 
prospective Contractholders, to the Reinsurer's insureds and as otherwise
required under applicable law. This Section 3.2 shall not apply (i) to
contracting efforts by third parties, including, but not limited to, PHCS acting
on behalf of the Reinsurer, for the purpose of developing managed care networks,
provided, however, that, the names of health care providers solicited by such
third parties shall not have been furnished by the Reinsurer, its employees or
agents, or (ii) following the Termination Date of this Agreement, as described
in the provisions of Article VIII hereof. The Reinsurer further agrees not to
replace a HMO Plan with a PHCS managed health care plan during the term of this
Agreement.

     (b) No party, nor any of its Affiliates, shall contact, solicit or contract
with any other party's full-time employees who have been engaged in the
activities covered by this Agreement without the consent of such other party.

     3.3 Inspection. Any party, or its designated representative, may inspect,
at the offices of the Company or the Reinsurer, as the case may be, where such
records are located, and conduct reasonable audits of, the papers and any and
all other books or documents of the Company or the Reinsurer reasonably relating
to the HMO Plans and the administrative responsibilities hereunder, during
normal business hours for such period as this Agreement is in effect or for as
long thereafter as the Company or the Reinsurer, as the case may be, seeks
performance by the other party pursuant to the terms of this Agreement. The
information obtained shall be used only for purposes relating to the reinsurance
provided under this Agreement and shall not be disclosed to any person without
the express permission of the other party, except to the extent that

                                        9
<PAGE>
 
disclosure is required by law. Each party's rights under this Section 3.3 shall
survive termination of this Agreement.

     3.4 Misunderstandings and Oversights. If any delay, omission, error or
failure to pay amounts due or to perform any other act required by this
Agreement is unintentional and caused by misunderstanding or oversight, the
Company and the Reinsurer will adjust the situation to what it would have been
had the misunderstanding or oversight not occurred. The party that first
discovers such oversight or incorrect act as a result of the misunderstanding
will notify the other parties in writing promptly upon discovery of the
misunderstanding or oversight. The parties shall act to correct the error,
omission or oversight within twenty (20) calendar days of notification of the
problem. This Section 3.4 shall not be construed as a waiver by any party of its
right to enforce strictly the terms of this Agreement.

     3.5 Reinstatements. If a HMO Plan reinsured hereunder that was terminated
or lapsed is reinstated while this Agreement is in effect, the reinsurance for
such HMO Plan shall be reinstated automatically as if such HMO Plan had not been
terminated or lapsed. All amounts received in connection with such reinstatement
shall be treated as Direct Paid Premiums.

     3.6 Contract Changes or Reserve Changes. The Company and the Reinsurer
shall share, based upon the percentages set forth in Section 2.1 and Schedule A,
in any increase or decrease in the Company's liability that results from any
change in the terms or conditions of any HMO Plan reinsured hereunder or in the
calculation of Reserves. The Company must provide written notification to the
Reinsurer within

                                       10
<PAGE>
 
fifteen (15) calendar days after any such change, if such change can reasonably
be expected to have a significant effect on the transactions contemplated by
this Agreement.

     3.7 Compliance with Applicable Laws and Regulations. It is the intention of
the parties that this Agreement comply with all existing applicable laws and
regulations, as from time to time are in effect, so that the agreement remains
in full force and the HMO Plans remain reinsured hereunder. Each of the parties
agrees to comply with all laws, ordinances, rules, regulations and orders of
regulatory bodies applicable to the transactions contemplated by this Agreement,
including those relating to the payment of commissions.

     3.8 Amendment and/or Termination Upon Failure to Comply. In the event that
it is determined by an insurance or health regulatory authority, the Internal
Revenue Service or any other federal, state or local regulatory authority or by
any party to this Agreement upon the advice of an insurance or health regulatory
authority or the Internal Revenue Service that this Agreement fails to conform
to, or that the intent of this Agreement cannot be effected as a result of, the
requirements of existing applicable laws and regulations and that this Agreement
may be brought into conformity with said requirements, or the intent of this
Agreement may be effected, only by means of a material change to this Agreement,
or in the event that such laws or regulations are changed subsequent to the
Effective Date and such change has a material adverse effect on any party or
requires a material change to this Agreement in order for this Agreement to
conform with applicable laws and regulations or for its intent to be

                                       11
<PAGE>
 
effected, the parties shall exercise reasonable efforts to reach an agreement to
amend this Agreement so as to return the parties to the economic position that
they would have been in had no such change occurred or so that both parties
share the economic detriment of such change proportionately. If the parties are
unable to reach an agreement to amend the Agreement, then the differences
between the parties shall be resolved through arbitration in accordance with the
provisions of Article XIII. In the event that any required change is not
material, this Agreement shall be amended in accordance with such requirement.

     3.9 Notification of Disapproval or Change in Law. The Company shall
promptly notify the Reinsurer of any actual or anticipated disapprovals or
required changes regarding this Agreement that are made by any insurance or
health regulatory authority or taxing authority and of any change in the laws,
regulations or rulings affecting this Agreement or related documents. The
Reinsurer shall be allowed to participate in the defense of this Agreement or
related documents on its own behalf with such authority after consultation with
the Company.

     3.10 Setoff. It is expressly understood that any debts or credits, matured
or unmatured, liquidated or unliquidated, arising or incurred pursuant to the
terms hereof, including but not limited to such debts and credits arising under
Articles IV, V and VI shall, at all times and under all circumstances relevant
to the rights and liabilities of the parties to this Agreement, be deemed mutual
debts or credits, as the case may be, and shall be set off, and only the net
balance shall be allowed or paid.

     3.11 Limitations on Liability. (a) The Reinsurer shall not indemnify or be
liable pursuant to this Agreement or otherwise for any of the Company's risk, to
the extent any damages result from the negligent acts or omissions to act,
reckless or intentional wrongs, fraud, oppression or bad faith of the Company.

shall be liable and indemnify the Reinsurer fully for all losses arising from
the negligent acts or omissions to act, reckless or intentional wrongs, fraud,
oppression or bad faith of the Company acting in connection with a HMO Plan
reinsured hereunder.

     (c) The Reinsurer shall be liable, based on the applicable percentages set
forth in Section 2.1 and Schedule A, and subject to the election permitted by

     (d) For purposes of this Agreement, any damages, claims, liabilities or
other expenses for which the Reinsurer shall be liable shall be net of the

herein shall limit either party's right to enter into a Change of Control

in any additional costs or expenses associated with such claim.

details of account with respect to the HMO Plans reinsured hereunder, setting
forth the data required in Schedules C and E.

Period, the Company shall supply the Reinsurer with a Quarterly Accounting
Report providing the data required in Schedules C and E. The Quarterly
Accounting Report shall be submitted within forty-five (45) calendar days of the
end of each calendar quarter.

     7.3 Settlements. Settlement of amounts payable between the Company and the
Reinsurer shall be made in a reasonably expeditious manner once the amounts or
estimates are known or determined. All settlement payments shall be made by wire
transfer with same or next day availability unless otherwise agreed.

     (a) Weekly Settlements. The Reinsurer shall make reimbursement payments to
the Company for estimated weekly cash claims paid by the Company. Such estimates
are to be mutually determined, and appropriately adjusted from time to time, to
reasonably approximate the timing and amounts of cash claim expenditures made by
the

                                       20
<PAGE>
 
Company and to minimize the quarterly settlement amounts with respect to claims.
Such payments are due weekly based upon a mutually agreed upon schedule.

     (b) Monthly Settlements. The Reinsurer shall make reimbursement payments to
the Company monthly for any actual or estimated monthly administrative expenses,
premium taxes, licenses, fees or assessments incurred by the Company. Such
payments are due within 20 Business Days after the end of each month in which
they were incurred. The Reinsurer's actual or estimated administrative or
commission expenses incurred are also deemed payable at that time. By mutual
agreement, certain expenses may be added to or deleted from this monthly
reimbursement.

     (c) Quarterly Settlements. Based upon the Quarterly Accounting Reports,
including Schedules C and E, settlement payment shall be made to the Company or
Reinsurer, as the case may be, within 45 calendar days from the end of such
quarter. If such reports or schedules are not finalized within this time frame,
a reasonable estimated payment shall be made followed by an adjustment payment.
The Quarterly Settlement payment shall represent settlement, net of any interim
reimbursements or other related settlement payments, of all amounts due during
that quarter and any mutually agreed upon adjustments to prior periods. The
quarterly calculation of this payment shall be substantially in the form of
Schedule E with any positive amounts listed on Line 24 of such Schedule being
payable from the Reinsurer to the Company and any negative amounts being payable
from the Company to the Reinsurer. For the


                                       21
<PAGE>
 
purpose of calculating interest on delayed payments relating to this quarterly
settlement payment, the parties agree that the due date is the 15th day (unless
such 15th day falls on a day other than a Business Day, in which case the due
date is the Business Day immediately preceding such 15th day) of the middle
month of the settlement quarter unless otherwise mutually agreed.

     (d) Other Settlements. Other settlement payments between the Company and
the Reinsurer such as payment adjustments, preliminary quarterly settlements,
withhold payout reimbursements or interest compensation may be made separately
or along with other settlement payments upon mutual agreement. For the purpose
of calculating interest on delayed payments relating to these payments, due
dates are to be mutually agreed upon if not otherwise specified in this
Agreement.

     7.4 Reconciliation. Each party shall have the right to review all
individual components of transactions entered into each Quarterly Accounting
Report, such as Premiums received, Commissions and Insurance Taxes, claims
incurred or paid, and similar items. The parties shall have a reasonable period
from the day the Quarterly Accounting Report is submitted to report any
deficiency in such report and to request an adjustment of any payment made to or
received by either party. Any amount due either party in connection with such
reconciliation shall be paid within forty-five (45) calendar days of the receipt
of notice that additional amounts are due.

     7.5 Best Efforts to Supply Actual Data. In preparing all reports required
in this Agreement, the Reinsurer and the Company shall make their best efforts
to supply the actual data. If the actual data cannot be supplied with the
appropriate report, the Reinsurer or the Company shall produce best estimates,
and shall provide amended reports based on actual data no more than forty-five
(45) days after such report was originally due.

     7.6 Interest Delayed Payments. Should any payment in connection with the
Settlements due the Company or the Reinsurer as set forth in Section 7.3 above
be delayed beyond its due date as defined or determined, such delayed payment
shall accrue interest during such period of delay at the Interest Compensation
Rate as defined on Schedule D. Interest is to be calculated based upon an
actual/365 day basis. Any such interest accrued or paid shall not be included in
Schedule C as a jointly shared income or expense item, but rather be paid
directly to the deficient party either separately or as a separate item added to
the Schedule E settlement. The application of this calculation shall also apply
to any over payments, with interest accruing back to the deficient party.

present to

                                       27

                     PAYMENTS UPON TERMINATION OF AGREEMENT

     9.1 Payments on Termination. (a) In the event that this Agreement shall be
terminated pursuant to Article VIII, a net accounting and settlement as to any
balance due under this Agreement shall be undertaken by the parties to this
Agreement (the "Terminal Accounting and Settlement"), which calculations shall

Company shall pay the amount owing to the Reinsurer. If the Terminal Accounting
and Settlement

                                       28

the period agreed by the parties.

     (c) Any payment required under the Terminal Accounting and Settlement by
the Company shall be paid by the Company no later than the day on which the
final Schedules C and E, as required by Section 9.l(b), are due. The Reinsurer
shall make any payment required to be made by the Reinsurer hereunder within ten
(10) calendar days of receipt of such final schedules. In the event that the
calculation for the payment required under the Terminal Accounting and
Settlement cannot be accurately calculated by such date, then an estimate shall
be paid with a supplemental accounting being made when the accurate information
shall become available.

     9.2 Supplemental Accounting. In the event that, subsequent to the Terminal
Accounting and Settlement, an adjustment is made with respect to any amount
taken into account in the Terminal Accounting and Settlement, or in the event
that the Company pays a Direct Paid Claim that accrued prior to the termination
hereof, a supplemental accounting shall be made. Any net amount owed to the
Reinsurer or the Company by reason of such supplemental accounting, plus any
interest due pursuant to Section 7.6, shall be paid promptly upon the completion
of such supplemental accounting.

applicable laws or regulations, approval of arrangements of the type
contemplated by this Agreement by one or more Federal, state or local
governmental or regulatory authorities is required, the receipt by the Company
and the Reinsurer of any and all such approvals shall be a condition precedent
to the other party's liability under this Agreement. Subject to Section 11.2, if
this condition precedent is not met by the Company or the Reinsurer by the
Effective Date, this Agreement shall be void as of the Effective Date.

     11.2 Extension of Time. In the event that the necessary approvals set forth

Company, payments due the Company on all reinsurance made, ceded, renewed or
otherwise becoming effective under this Agreement shall, subject to Section
12.2, be payable by the Reinsurer directly to the Company or to its liquidator,
receiver, or statutory successor on the basis of the liability of the Company
and the Reinsurer under the HMO Plans reinsured hereunder without diminution
because of the insolvency of the Company.

     12.2 Claims. In the event of the insolvency of the Company, the Reinsurer
shall be given written notice of the pendency of a claim against the insolvent
Company on a HMO Plan reinsured hereunder within a reasonable time after such
claim is filed in the insolvency proceeding. During the pendency of such claim,
the Reinsurer may investigate such claim and interpose, at its own expense, in
the proceeding where such claim is to be adjudicated, any defense or defenses
which it may deem available to the Company or its liquidator or receiver or
statutory successor. The expense thus incurred by the Reinsurer shall be
chargeable' subject to court approval, against the insolvent Company as part of
the expense of liquidation to the extent of a proportionate share of

                                       31
<PAGE>
 
the benefit which may accrue to the Company solely as a result of the defense
undertaken by the Reinsurer. Where two or more assuming reinsurers are involved
in the same claim and a majority in interest elect to interpose defenses to such
claim, the expense shall be apportioned in accordance with the terms of this
Agreement as though such expense had been incurred by the Company.

same shall be decided by arbitration. Three arbitrators will decide any dispute
or difference. The arbitrators must be disinterested officers or retired
officers of health maintenance organizations or managed health care companies,
or insurance companies with experience in managed health care, other than the
parties to this Agreement or their Affiliates. Each of the Company and the
Reinsurer agrees to appoint one of the arbitrators with the third, the "Umpire,"
to be chosen by the other arbitrators. In the event that either such party
should fail to choose an arbitrator within 30 days following a written request
by the other party to do so, the requesting party may choose an Umpire before
entering upon arbitration. In the event that the two arbitrators shall not be
able to agree on the choice of the Umpire within 30 days following their
appointment, each arbitrator shall nominate five

                                       32
<PAGE>
 
candidates within 10 days thereafter, four of whom the other arbitrator shall
decline, and the Umpire shall be chosen from the two remaining nominees by the
President of the American Arbitration Association.

     13.2 Decision of Arbitrators: Expenses. The arbitrators shall consider
customary and standard practices in the HMO and managed health care insurance
businesses. They shall decide by a majority vote of the arbitrators. There shall
be no appeal from their written decision. Judgment may be entered on the
decision. Each party shall bear the expense of its own arbitrator and outside
attorney fees, and shall jointly and equally bear with the other party the
expenses of the third arbitrator.

     13.3 Applicable Law: Survival. Any arbitration instituted pursuant to this
Article XIII shall be held in Connecticut and the laws of the State of
Connecticut and, to the extent applicable, the Federal Arbitration Act shall
apply. This Article XIII shall survive termination of this Agreement.

     13.4 Other Actions. Submission of a matter to arbitration shall be a
condition precedent to any right to institute a proceeding at law or in equity
concerning such matter, except for injunctive or other provisional relief
pending the arbitration of a matter subject to arbitration pursuant to this
Agreement.

Agreement is in effect. that it will maintain Stop-Loss Reinsurance with respect
to the HMO Plans in effect, with deductibles, coverages and limits of liability
that are substantially the same as those that apply under the Stop Loss
Reinsurance contract or contracts of the Company that are in effect on the
Effective Date, a copy or copies of which are attached as Exhibit 1; provided,
however, that each Stop Loss Reinsurance contract or contracts of the Company
relating to HMO Plans must provide coverage with respect to claims relating to
any periods during which the Company is obligated to

                                       16

provide services with respect to HMO Plans, without regard to (i) the failure of
the Company to remain qualified to conduct the business for which it is
organized, or (ii) the insolvency or the commencement of supervision,
conservation, rehabilitation, liquidation or similar proceedings against the
Company. In the event that any Stop Loss Reinsurance contract issued to the
Company does nor meet the requirements of this Section 3.19 at the Effective
Date, or at any time thereafter, the Company will obtain substitute Stop Loss
Reinsurance meeting such requirements from a qualified reinsurer, including the
Reinsurer.

after the end of the calendar year, the Company shall provide the Reinsurer with
a Statement of Actuarial Opinion certifying the adequacy of the reserves which
are covered under this Agreement. In addition, the Actuarial Opinion must state
whether or not the reserves covered under this Agreement meet the minimum
standards of all states where the Company is licensed, and if not the difference
between the Company's reserves and state minimums. The Actuarial Opinion shall
meet the requirements as set forth in the NAIC's Actuarial Opinion and
Memorandum Regulation. The Opinion shall be signed by the Company's "Appointed
Actuary."

Company in accordance with the settlements required by Section 7.3 of this
Agreement.

for its Administrative Expenses (not including pre-marketing expenses),

Reinsurer upon request.

<PAGE>
 
should be paid, and elects to assume liability for its applicable percentage (as
set forth in Section 2.1 and Schedule A) of the claim as originally presented,
the Reinsurer shall not share in any additional costs or expenses associated
with such claim.

                                   ARTICLE VII

                            ACCOUNTING AND REPORTING

details of account with respect to the HMO Plans reinsured hereunder, setting
forth the data required in Schedules C, E and F.

     7.2 Ouarterly Accounting Reports. Following the end of each Accounting
Period, the Company shall supply the Reinsurer with a Quarterly Accounting
Report providing the data required in Schedules C and E. The Quarterly
Accounting Report shall be submitted within forty-five (45) calendar days of the
end of each calendar quarter.

     7.3 Settlements. Settlement of amounts payable between the Company and the
Reinsurer shall be made in a reasonably expeditious manner once the amounts or
estimates are known or determined. All settlement payments shall be made by wire
transfer with same or next day availability unless otherwise agreed.

                                       20
<PAGE>
 
     (a) Weekly Settlements. The Reinsurer shall make reimbursement payments to
the Company for estimated weekly cash claims paid by the Company. Such estimates
are to be mutually determined, and appropriately adjusted from time to time, to
reasonably approximate the timing and amounts of cash claim expenditures made by
the Company and to minimize the quarterly settlement amounts with respect to
claims. Such payments are due weekly based upon a mutually agreed upon schedule.

     (b) Monthly Settlements. The Reinsurer shall make reimbursement payments to
the Company monthly for any actual or estimated monthly administrative expenses.
premium taxes, licenses, fees or assessments incurred by the Company. Such
payments are due within 20 Business Days after the end of each month in which
they were incurred. Reinsurer's actual or estimated administrative or commission
expenses incurred are also deemed payable at that time. By mutual agreement,
certain expenses may be added to or deleted from this monthly reimbursement.

     (c) Quarterly Settlements. Based upon the Quarterly Accounting Reports,
including Schedules C, E and F, settlement payment shall be made to the Company
or the Reinsurer, as the case may be, within 45 calendar days from the end of
such quarter. If such reports or schedules are not finalized within this time
frame, a reasonable estimated payment shall be made followed by an adjustment
payment. The Quarterly Settlement payment shall represent settlement, net of any
interim reimbursements or other related settlement payments, of all amounts due
during that

                                       21
<PAGE>
 
quarter and any mutually agreed upon adjustments to prior periods. The quarterly
calculation of this payment shall be substantially in the form of Schedule E
with any positive amounts listed on Line 24 of such Schedule being payable from
the Reinsurer to the Company and any negative amounts being payable from the
Company to the Reinsurer. For the purpose of calculating interest on delayed
payments relating to this quarterly settlement payment, the parties agree that
the due date is the 15th day (unless such 15th day falls on a day other than a
Business Day, in which case the due date is the Business Day immediately
preceding such 15th day) of the middle month of the settlement quarter unless
otherwise mutually agreed.

     (d) Other Settlements. Other settlement payments between the Company and
the Reinsurer such as payment adjustments, preliminary quarterly settlements,
withhold payout reimbursements or interest compensation may be made separately
or along with other settlement payments upon mutual agreement. For the purpose
of calculating interest on delayed payments relating to these payments, due
dates are to be mutually agreed upon if not otherwise specified in this
Agreement.

     7.4 Reconciliation. Each party shall have the right to review all
individual components of transactions entered into each Quarterly Accounting
Report, such as Premiums received, Commissions and Insurance Taxes, claims
incurred or paid, and similar items. The parties shall have a reasonable period
from the day the Quarterly Accounting Report is submitted to report any
deficiency in such report and to request

                                       22
<PAGE>
 
an adjustment of any payment made to or received by either party. Any amount due
either party in connection with such reconciliation shall be paid within
forty-five (45) calendar days of the receipt of notice that additional amounts
are due.

     7.5 Best Efforts to Supply Actual Data. In preparing all reports required
in this Agreement, the Reinsurer and the Company shall make their best efforts
to supply the actual data. If the actual data cannot be supplied with the
appropriate report, the Reinsurer or the Company shall produce best estimates,
and shall provide amended reports based on actual data no more than forty-five
(45) calendar days after such report was originally due.

     7.6 Interest Delayed Payments. Should any payment in connection with the
Quarterly Settlements due the Company or the Reinsurer in accordance with
Section 7.3 above be delayed beyond its due date as defined or determined, such
delayed payment shall accrue interest during such period of delay at the
Interest Compensation Rate as defined on Schedule E. Interest is to be
calculated based upon an actual/365 day basis. Any such interest accrued or paid
shall not be included in Schedule C as a jointly shared income or expense item,
but rather be paid directly to the deficient party either separately or as a
separate item added to the Schedule F settlement. The application of this
calculation shall also apply to any over payments, with interest accruing back
to the deficient party.

applicable to such HMO Plan, or continuation managed care contract issued by the

     9.1 Payments on Termination. (a) In the event that this Agreement shall be
terminated pursuant to Article VIII, a net accounting and settlement as to any
balance due under this Agreement shall be undertaken by the parties to this
Agreement (the "Terminal Accounting and Settlements"), which calculations shall

Company shall pay the amount owing to the Reinsurer. If the Terminal Accounting
and Settlement

                                       28

the period agreed by the parties.

     (c) Any payment required under the Terminal Accounting and Settlement by
the Company shall be paid by the Company no later than the day on which the
final Schedules C, E and F, as required by Section 9.1(b), are due. The
Reinsurer shall make any payment required to be made by the Reinsurer hereunder
within ten (10) calendar days of receipt of such final schedules. In the event
that the calculation for the payment required under the Terminal Accounting and
Settlement cannot be accurately calculated by such date, then an estimate shall
be paid, with a supplemental accounting being made when the accurate information
shall become available.

     9.2 Supplemental Accounting. In the event that, subsequent to the Terminal
Accounting and Settlement, an adjustment is made with respect to any amount
taken into account in the Terminal Accounting and Settlement, or in the event
that the Company pays a Direct Paid Claim that accrued prior to the termination
hereof, a supplemental accounting shall be made. Any net amount owed to the
Reinsurer or the Company by reason of such supplemental accounting, plus any
interest due pursuant to Section 7.6, shall be paid promptly upon the completion
of such supplemental accounting.

applicable laws or regulations, approval of arrangements of the type
contemplated by this Agreement by one or more Federal, state or local
governmental or regulatory authorities is required, the receipt by the Company
and the Reinsurer of any and all such approvals shall be a condition precedent
to the other party's liability under this Agreement. Subject to Section 11.2, if
this condition precedent is not met by the Company or the Reinsurer by the
Effective Date, this Agreement shall be void as of the Effective Date.

     11.2 Extension of Time. In the event that the necessary approvals set forth
in Section 11.1 have not been obtained by the Company or the Reinsurer as of the

Company, payments due the Company on all reinsurance made, ceded, renewed or
otherwise becoming effective under this Agreement shall, subject to Section
12.2, be payable by the Reinsurer directly to the Company or to its liquidator,
receiver, or statutory successor on the basis of the liability of the Company
and the Reinsurer under the HMO Plans reinsured hereunder without diminution
because of the insolvency of the Company.

     12.2 Claims. In the event of the insolvency of the Company, the Reinsurer
shall be given written notice of the pendency of a claim against the insolvent
Company on a HMO Plan reinsured hereunder within a reasonable time after such
claim is filed in the insolvency proceeding. During the pendency of such claim,
the Reinsurer may investigate such claim and interpose, at its own expense, in
the proceeding where such claim is to be adjudicated, any defense or defenses
which it may deem available to the Company or its liquidator or receiver or
statutory successor. The expense thus incurred by the Reinsurer shall be
chargeable, subject to court approval, against the insolvent Company as part of
the expense of liquidation to the extent of a proportionate share of

                                       31
<PAGE>
 
the benefit which may accrue to the Company solely as a result of the defense
undertaken by the Reinsurer. Where two or more assuming reinsurers are involved
in the same claim and a majority in interest elect to interpose defenses to such
claim, the expense shall be apportioned in accordance with the terms of this
Agreement as though such expense had been incurred by the Company.

or difference. The arbitrators must be disinterested officers or retired
officers of health maintenance organizations or managed health care companies,

parties to this Agreement or their Affiliates. Each of the Company and the
Reinsurer agrees to appoint one of the arbitrators with the third, the "Umpire,"

able to agree on the choice of the Umpire within 30 days following their
appointment, each arbitrator shall nominate five

                                       32

decline. and the Umpire shall be chosen from the two remaining nominees by the
President of the American Arbitration Association.

customary and standard practices in the HMO and managed health care insurance
businesses. They shall decide by a majority vote of the arbitrators. There shall
be no appeal from their written decision. Judgment may be entered on the
decision of the arbitrators by any court having jurisdiction. Each party shall
bear the expense of its own arbitrator and outside attorney fees, and shall
jointly and equally bear with the other party the expenses of the third
arbitrator.

     13.3 Applicable Law: Survival. Any arbitration instituted pursuant to this
Article XIII shall be held in New York, New York and the laws of the State of
New York and, to the extent applicable, the Federal Arbitration Act shall apply.
This Article XIII shall survive termination of this Agreement.

     13.4 Other Actions. Submission of a matter to arbitration shall be a
condition precedent to any right to institute a proceeding at law or in equity
concerning such matter, except for injunctive or other provisional relief
pending the arbitration of a matter subject to arbitration pursuant to this
Agreement.

coverages and limits of liability that are substantially the same as those that
apply under the Stop Loss Reinsurance contract or contracts of the Company that

Exhibit I; provided, however, that each Stop Loss Reinsurance contract or
contracts of the Company relating to HMO or POS Plans must provide coverage with
respect to claims relating to any periods during which the Company is obligated
to provide services with respect to HMO or POS Plans, without regard to (i) the
failure of the Company to remain qualified to conduct the business for which it
is organized, or (ii) the insolvency or the commencement of supervision,
conservation, rehabilitation, liquidation or similar proceedings against the
Company. In the event that any Stop Loss Reinsurance contract issued to the
Company does not meet the requirements of this Section 3.19 at the Effective

Reinsurance meeting such requirements from a qualified reinsurer, including the
Reinsurer.

the claim as originally presented, the Reinsurer or PHS (Bermuda), as the case
may be, shall not share in any additional costs or expenses associated with such

                            ACCOUNTING AND REPORTING
                            ---------- -------------

     7.1  Reinsurance Accounting. The Company shall maintain separate books or
          ----------------------                                              
details of account with respect to the HMO and POS Plans reinsured hereunder,
setting forth the data required in Schedules C, E and F.

     7.2  Ouarterly Accounting Reports. Following the end of each Accounting
          ----------------------------                                      
Period, the Company shall supply the Reinsurer and PHS (Bermuda) with a
Quarterly Accounting Report providing the data required in Schedules C and E.
The Quarterly


                                       22
<PAGE>
 
Accounting Report shall be submitted within forty-five (45) calendar days of the
end of each calendar quarter.

          7.3  Settlements. Settlement of amounts payable between the Company,
               -----------                                                    
the Reinsurer and PHS (Bermuda) shall be made in a reasonably expeditious manner
once the amounts or estimates are known or determined. All settlement payments
shall be made by wire transfer with same or next day availability unless
otherwise agreed.



     (a) Weekly Settlements. Reinsurer shall make reimbursement payments to the
         ------------------                                                    
Company for estimated weekly cash claims paid by the Company. Such estimates are
to be mutually determined, and appropriately adjusted from time to time, to
reasonably approximate the timing and amounts of cash claim expenditures made by
the Company and to minimize the quarterly settlement amounts with respect to
claims. Such payments are due weekly based upon a mutually agreed upon schedule.



     (b) Monthly Settlements. Reinsurer shall make reimbursement payments to the
         -------------------                                                    
Company monthly for any actual or estimated monthly administrative expenses,
premium taxes, licenses, fees or assessments incurred by the Company. Such
payments are due within 20 Business Days after the end of each month in which
they were incurred. Reinsurer's actual or estimated administrative or commission
expenses incurred are also deemed payable at that time. By mutual agreement,
certain expenses may be added to or deleted from this monthly reimbursement.


                                       23
<PAGE>
 
     (c) Quarterly Settlements. Based upon the Quarterly Accounting Reports,
         ---------------------                                              
including Schedules C, E and F, settlement payment or payments shall be made to
the Company or Reinsurer, or PHS Bermuda as the case may be, within 45 calendar
days from the end of such quarter. If such reports or schedules are not
finalized within this time frame, reasonable estimated payments shall be made
followed by adjustment payments. The Quarterly Settlement payments shall
represent settlement, net of any interim reimbursements or other related
settlement payments, of all amounts due during that quarter and any mutually
agreed upon adjustments to prior periods. The quarterly calculation of this
payment shall be substantially in the form of Schedule E with any positive
amounts listed on Line 24 of such Schedule being payable from the Reinsurer to
the Company and any negative amounts being payable from the Company to the
Reinsurer. For the purpose of calculating interest on delayed payments relating
to this quarterly settlement payment, the parties agree that the due date is the
15th day (unless such 15th day falls on a day other than a Business Day, in
which case the due date is the Business Day immediately preceding such 15th day)
of the middle month of the settlement quarter unless otherwise mutually agreed.



     (d) Other Settlements. Other settlement payments between the Company and
         -----------------                                                   
the Reinsurer such as payment adjustments, preliminary quarterly settlements,
withhold payout reimbursements or interest compensation may be made separately
or along with other settlement payments upon mutual agreement. For the purpose
of calculating


                                       24
<PAGE>
 
interest on delayed payments relating to these payments, due dates are to be
mutually agreed upon if not otherwise specified in this Agreement.

     7.4  Reconciliation. Each party shall have the right to review all
          --------------                                               
individual components of transactions entered into each Quarterly Accounting
Report, such as Premiums received, Commissions and Insurance Taxes, claims
incurred or paid, and similar items. The parties shall have a reasonable period
from the day the Quarterly Accounting Report is submitted to report any
deficiency in such report and to request an adjustment of any payment made to or
received by any party. Any amount due any party in connection with such
reconciliation shall be paid within forty-five (45) calendar days of the receipt
of notice that additional amounts are due.

     7.5  Best Efforts to Supply Actual Data. In preparing all reports required
          ----------------------------------                                   
in this Agreement, the Reinsurer, PHS (Bermuda) or the Company, as the case may
be, shall make its best efforts to supply the actual data. If the actual data
cannot be supplied with the appropriate report, the Reinsurer, PHS (Bermuda) or
the Company, as the case may be, shall produce best estimates, and shall provide
amended reports based on actual data no more than forty-five (45) days after
such report was originally due.

     7.6  Interest on Delayed Payments. Should any payment in connection with
          ----------------------------                                       
the Quarterly Settlements due the Company, PHS (Bermuda) or the Reinsurer as set
forth in Section 7.3 above be delayed beyond its due date, as defined or
determined, such delayed payment shall accrue interest during such period of
delay at the Interest Compensation Rate as defined on Schedule D. Interest is to
be calculated based upon


                                       25
<PAGE>
 
an actual/365 day basis. Any such interest accrued or paid shall not be included
in Schedule C as a jointly shared income or expense item, but rather be paid
directly to the deficient party either separately or as a separate item added to
the Schedule E settlement. The application of this calculation shall also apply
to any over payments, with interest accruing back to the deficient party.

     7.7  Interest on Cash Reserves. The Reinsurer shall pay PHS (Bermuda) at
          -------------------------                                          
the Investment Rate as defined in Schedule D for any net cumulative cash reserve
balances held by the Reinsurer for the benefit of PHS (Bermuda) after adjusting
for any settlement payments. Interest will be calculated quarterly based upon an
actual/365 day basis and is due and payable at the time of the Quarterly
Settlement. Any such interest accrued or paid shall not be included in Schedule
C as a jointly shared income or expense item, but will be paid directly to PHS
(Bermuda) either separately or as a separate item added to the Schedule E
settlement. Such interest shall be calculated and reported as set forth in
Schedule G.

to any HMO or POS Plan, as the case may be, shall terminate on the date the

incurred prior to the date of such termination are satisfied. The Contract
Termination Date under this Section 8.4 shall be the 180th day following the
giving of the notice required by this Section 8.4.



     8.5  Automatic Termination. If, at the end of an Accounting Period, none of

for health insurance contracts issued by the Reinsurer in multi-choice

($5,000,000) on the first anniversary of the implementation of this Agreement,
then any party May, within forty-five (45) days thereafter, elect to terminate
this Agreement. The Termination Date shall be ninety (90) days thereafter. The

Plans are available for sale under the Marketing and Services Agreement. The
Contractholder of each HMO or POS Plan reinsured hereunder shall, in compliance
with applicable law, be given the choice of terminating its coverage at the
Termination Date or continuing coverage under such Contract until the Renewal

Agreement shall be deemed to be terminated as of the effective date of the
Change of Control except with respect to the provisions regarding the
administration of the HMO and POS Plans continued under this Section 8.7 which
provisions shall be deemed to survive such

Renewal Date applicable to such HMO or POS Plan, or continuation managed care
contract issued by the Company (collectively, "Continuation Plans,") following
the Contract Termination Date. The Contract Termination Date under this Section
8.7 shall be the effective date of the Change of Control.

     8.8  Termination for Cause. (a) In the event that any party shall default
          ---------------------

not carried out according to its terms, each of the non-defaulting parties shall
have the right to terminate this Agreement upon delivery of written notice of
such termination to the defaulting party, which shall be effective on receipt,
without prejudice to any other

grossly negligent conduct with respect to its duties and obligations under this
Agreement or the Marketing and Services Agreement, each of the other parties
shall have the right to terminate this Agreement upon delivery of written notice

                            ACCOUNTING AND REPORTING
                            ---------- --- ---------

     7.1  Reinsurance Accounting. The Company shall maintain separate books or
          ----------------------                                              
details of account with respect to the Health Insurance Contracts reinsured
hereunder, setting forth the data required in Schedules C, E and F.

     7.2  Quarterly Accounting Reports. Following the end of each Accounting
          ----------------------------

         ------------------                                                  
PHS New York for estimated weekly cash claims paid by PHS New York. Such
estimates are to be mutually determined, and appropriately adjusted from time to
time, to reasonably approximate the timing and amounts of cash claim
expenditures made by PHS New York and to minimize the quarterly settlement
amounts with respect to claims. Such payments are due weekly based upon a
mutually agreed upon schedule.

administrative expenses or assessments incurred by them. Such payments are due
within 20 Business Days after the end of each month in which they were incurred.
The Company's actual or estimated administrative expenses, premium taxes, fees,
assessments or commission expenses incurred are also deemed payable at that
time. By mutual agreement, certain expenses may be added to or deleted from this
monthly reimbursement. PHS New York shall be reimbursed for any amounts owed,
net of any reimbursements made as specified in Sections 5.2 and 6.1. Such
amounts are subject to the settlement process described herein and shall be
included in Schedules C and E as part of the Quarterly Accounting Reports.



     (c) Quarterly Settlements. Based upon the Quarterly Accounting Reports,
         ---------------------                                              
including Schedules C, E and F, settlement payment shall be made to the Company
or Reinsurer, as the case may be, within 45 calendar days from the end of such
quarter. If such reports or schedules are not finalized within this time frame,
a reasonable estimated payment shall be made followed by an adjustment payment.
The Quarterly Settlement payment shall represent settlement, net of any interim
reimbursements or other related settlement payments, of all amounts due during
that quarter and any mutually agreed upon adjustments to prior periods. The
quarterly calculation of this payment shall be substantially in the form of
Schedule E with any positive amounts listed on Line 24 of such Schedule being
payable from the Company to the Reinsurer and any negative amounts being payable
from the Reinsurer to the Company. For the purpose of calculating interest on
delayed payments relating to this quarterly settlement

                                       19

payment, the parties agree that the due date is the 15th day of the middle month
of the settlement quarter unless otherwise mutually agreed.

         -----------------                                                    
Reinsurer, and PHS New York such as payment adjustments, preliminary quarterly
settlements, withhold payout reimbursements or interest compensation may be made
separately or along with other settlement payments upon mutual agreement. For
the purpose of calculating interest on delayed payments relating to these
payments, due dates are to be mutually agreed upon if not otherwise specified in
this Agreement.

     7.4  Reconciliation. Each party shall have the right to review all
          --------------                                              
individual components of transactions entered into each Quarterly Accounting
Report, such as Premiums received, Commissions and Insurance Taxes, claims
incurred or paid, and similar items. The parties shall have a reasonable period
from the day the Quarterly Accounting Report is submitted to report any
deficiency in such report and to request an adjustment of any payment made to or
received by either party. Any amount due either party in connection with such
reconciliation shall be paid within forty-five (45) calendar days of the receipt
of notice that additional amounts are due.

     7.5  Best Efforts to Supply Actual Data. In preparing all reports required
          ----------------------------------

to supply the actual data. If the actual data cannot be supplied with the
appropriate report, the Reinsurer or the

Company shall produce best estimates, and shall provide amended reports based on
actual data no more than forty-five (45) calendar days after such report was
originally due.

          -------------------------                                           
Quarterly Settlements due the Company, the Reinsurer, of PHS New York as set
forth in Section 7.3 above be delayed beyond its due date as defined or
determined, such delayed payment shall accrue interest during such period of
delay at the Interest Compensation Rate as defined on Schedule D. Interest is to
be calculated based upon an actual/365 day basis. Any such interest accrued or
paid shall not be included in Schedule C as a jointly shared income or expense
item, but rather be paid directly to the deficient party either separately or as
a separate item added to the Schedule E settlement. The application of this
calculation shall also apply to any over payments, with interest accruing back
to the deficient party.

     7.7  Interest on Cash Reserves. The Company shall pay the Reinsurer at the
          -------------------------                                            
Investment Rate as defined in Schedule D for any net cumulative cash reserve
balances held by the Company for the benefit of the Reinsurer after adjusting
for any settlement payments. Interest will be calculated quarterly based upon an
actual/36S day basis and is due and payable at the time of the Quarterly
Settlement. Any such interest accrued or paid shall not be included in Schedule
C as a jointly shared income or expense item, but will be paid directly to the
Reinsurer either separately or as a separate item added to the Schedule E
settlement. Such interest shall be calculated and reported as set forth in
Schedule F.

and the Reinsurer (or PHS, as applicable) of any and all such approvals shall be
a condition precedent to the other party's liability under this Agreement.
Subject to Section 11.2, if this condition precedent is not met by the Company
or the Reinsurer by the Effective Date, this Agreement shall be void as of the
Effective Date.

     11.2  Extension of Time. In the event that the necessary approvals set
           -----------------

obligation of the Company to cede reinsurance under this Agreement, on or before
the Effective Date hereof, the Reinsurer shall deliver to the Company an
agreement by PHS to guarantee the solvency of the Reinsurer. Such agreement

           -------------------------                                       
Company, payments due the Company on all reinsurance made, ceded, renewed or
otherwise becoming effective under this Agreement shall, subject to Section
12.2, be payable by the Reinsurer directly to the Company or to its liquidator,
receiver, or statutory successor on the basis of the liability of the Company
under the Health Insurance Contracts reinsured hereunder without diminution
because of the insolvency of the Company.

     12.2  Claims. In the event of the insolvency of the Company, the Reinsurer
           ------
shall be given written notice of the pendency of a claim against the insolvent
Company on a Health Insurance Contract reinsured hereunder within a reasonable
time after such claim is filed in the insolvency proceeding. During the pendency
of such claim, the Reinsurer may investigate such claim and interpose, at its
own expense, in the proceeding where such claim is to be adjudicated, any
defense or defenses which it may deem available to the Company or its liquidator
or receiver or statutory successor. The expense thus incurred by the Reinsurer
shall be chargeable, subject to court approval, against the insolvent Company as
part of the expense of liquidation to the extent of a proportionate share of the
benefit which may accrue to the Company solely as a result of the defense
undertaken by the Reinsurer. Where two or more assuming reinsurers are involved
in the same claim and a majority in interest elect to interpose

                                       29

defenses to such claim, the expense shall be apportioned in accordance with the
terms of this Agreement as though such expense had been incurred by the Company.

other party to do so, the requesting party may choose an Umpire before entering
upon arbitration. In the event that the two arbitrators shall not be able to
agree on the choice of the Umpire within 30 days following their appointment,
each arbitrator shall nominate five candidates within 10 days thereafter, four
of whom the other arbitrator shall decline, and the Umpire shall be chosen from

decision. Judgment may be entered on the decision of the arbitrators by any
court having jurisdiction. Each party shall bear the expense of its own
arbitrator and outside attorney fees, and shall jointly and equally bear with
the other party the expenses of the third arbitrator.

condition precedent to any right to institute a proceeding at law or in equity
concerning such matter, except for injunctive or other provisional relief
pending the arbitration of a matter subject to arbitration pursuant to this

     -----------                                                     
     recredentialing of all Participating Physicians in accordance with PHS and
     GBIPA credentialing guidelines.  PHS shall promptly notify GBIPA of any
     Participating Physicians known by PHS to have (i) retired or relocated from
     the Service Area; (ii) terminated participation in all PHS Programs; or
     (iii) terminated their status as a Participating Physician. PHS may
     terminate any Participating Physician from participation in all its
     Programs in accordance with the due process protocols set forth in the
     Office Manual. PHS shall develop and maintain grievance procedures for
     Members and Participating Physicians.

2.3  Office Manual.  PHS shall maintain the Office Manual for the benefit of
     -------------                                                          
     PHS, GBIPA and Participating Physicians, which shall set forth the
     programs, procedures, rules, regulations and protocols of GBIPA and PHS,
     relating to the delivery of Covered Services by Participating Physicians
     and participation of Participating Physicians as members of GBIPA.  PHS
     shall furnish an Office Manual to GBIPA and each Participating Physician
     and shall send supplements or revisions to the Office Manual to GBIPA and
     Participating Physicians prior to the effective date thereof.  PHS shall
     develop Performance Standards which it shall use to monitor performance of
     Participating Physicians.  PHS shall promptly advise GBIPA (or the Advisory
     Committee if such Committee is assigned responsibility by GBIPA for
     performance reviews of Participating Physicians) if a Participating
     Physician fails to satisfy such Performance Standards.

2.4  PHS Programs.  PHS shall develop and administer programs to enhance the
     ------------                                                           
     delivery of Covered Services to Members, including programs to achieve more
     effective quality controls, cost and utilization efficiencies.  PHS shall
     consult with the Advisory Committee in the development and implementation
     of programs and performance standards that would materially affect the

     collected utilization, unit cost, per member per month medical expense and
     related data associated with GBIPA Membership and the membership associated
     with GBIPA's pricing region (currently Western Connecticut).  PHS agrees to
     work with GBIPA (or its designee) in the evaluation of this data in order
     to address trends in utilization, unit costs, and/or per member per month
     medical expenses.  PHS will make such information available to GBIPA on a
     "CPT-4" code basis, and other basis as determined reasonably by GBIPA and
     PHS.  PHS will provide GBIPA access to the data at no cost to GBIPA;
     provided, however, that PHS shall not be required to provide GBIPA such
     computer access if access to data would result in disclosure of information
     that is proprietary to PHS, information that relates to vendors other than
     GBIPA, or confidential information, the disclosure of which may result in a
     breach of a confidentiality agreement between PHS and another party.
     Special reports will be provided to GBIPA without charge if the parties
     agree that such reports will assist GBIPA in lowering its health care
     costs, or the utilization of Participating Physicians.

2.6  Advisory Committee.  GBIPA shall participate in the Advisory Committee and
     ------------------

     relating to the PHS network.  The Advisory Committee and such other
     committees shall have proportional representation among all IPAs, PHOs or
     individual physicians represented therein in accordance with commercial
     membership, inclusive of fully insured and administrative services only
     members, by IPA in relation to PHS commercial membership in the State of
     Connecticut.  The President of GBIPA shall serve as an ex officio member of
                                                            ----------

                      ARTICLE III - GBIPA RESPONSIBILITIES
                      ------------------------------------

3.1  GBIPA Services.  PHS hereby retains GBIPA to render Covered Services from
     --------------                                                           
     the Effective Date to the Termination Date to Members through Participating
     Physicians and where appropriate, Consultant Physicians.  Participating
     Physicians, and not GBIPA, shall be solely responsible for all medical
     advice provided to and treatment rendered by Participating Physicians and
     Consultant Physicians.  GBIPA represents that it is authorized to act as
     the agent for each Participating Physician for purposes of entering into
     this Agreement.  GBIPA shall not be responsible for the provision of
     Covered Services that are (i) Contracted Services; (ii) inpatient hospital
     services by employees or staff of a hospital; (iii) Covered Services
     rendered to Members by non-GBIPA participating Physicians.  All Covered
     Services rendered by Participating Physicians shall be subject to the terms
     and conditions of this Agreement and the Physician Agreement.

3.2  Quality of Medical Care.  GBIPA shall use its best efforts to ensure that
     -----------------------                                                  
     Covered Services provided to Members by Participating Physicians are of a
     quality of medical care that is in conformity with accepted medical care
     and surgical practices of the American Medical Association and the practice
     prevailing in the Service Area.

3.3  Availability of Services.  GBIPA shall provide for the availability of
     ------------------------                                              
     Covered Services within the Service Area at such times and in such
     locations as shall be required to satisfy the needs of GBIPA Members and as
     shall be necessary to enable GBIPA to discharge its obligations hereunder.

     PHS will consult with the Advisory Committee with respect to future actions
     to be taken to permit compliance as set forth in the preceding sentence.

3.4  Medical Advice.  GBIPA and Participating Physicians shall be solely
     --------------                                                     
     responsible for all medical advice and treatment rendered to Members
     receiving medical care from Participating Physicians and for the
     performance of Covered Services.

3.5  Training  Each Participating Physician will have the training and
     ----------                                                       
     experience in the field in which they perform Covered Services.  GBIPA
     agrees that each Participating Physician shall enter into a Physician
     Agreement with GBIPA and GBIPA will take such further acts as necessary or
     desirable to amend the Physician Agreement upon reasonable request of PHS.

3.6  PHS Rules.  GBIPA shall comply with PHS programs, rules and protocols
     ---------                                                            
     (collectively, "Rules") adopted by PHS in furtherance of Article II hereof;
     provided, however, that no amendments or modifications to the Rules shall
     be made without GBIPA's consent that will have the effect of (i) adversely
     affecting any rights or remedies of GBIPA as against PHS or any
     Participating Physician; (ii) adding to, increasing or adversely affecting
     (as to GBIPA) any obligations of GBIPA to PHS to any Participating
     Physician; or (iii) amending or modifying any sanctions, penalties or
     termination protocols of PHS or against any Participating Physician or the
     process for sanctioning, penalizing or terminating any Participating
     Physician from PHS Programs or appealing decisions or terminating any
     Participating Physician from PHS Programs or appealing the decisions with
     respect thereto.  GBIPA shall use its best efforts to ensure that
     Participating Physicians comply with all policies and procedures as set
     forth in the Office Manual and all applicable law.

3.7  Adequacy of Network.  GBIPA shall at all times maintain a sufficient number
     -------------------                                                        
     of Participating Physicians to provide Covered Services hereunder.  If PHS
     believes at any time that the number of Participating Physicians, taken as
     a whole or within any specialty, including without limitation, 

                                       5
<PAGE>
 
     primary care, is insufficient, it shall consult with GBIPA and PHS and
     GBIPA shall jointly develop a plan to correct such insufficiency as
     expeditiously as possible. Notwithstanding the foregoing, in the event that
     PHS reasonably and in good faith determines that there is an unmet need
     and/or insufficient delivery system capacity for a specific physician
     service and has identified one or more physicians that satisfy its
     credentialing criteria, PHS may contract directly with such physician if
     GBIPA does not agree, after notice from PHS, to admit the physician as a
     Participating Physician.

3.8  Hold Harmless.  GBIPA agrees that it shall look solely to PHS for payment
     -------------                                                            
     for Covered Services provided to Members by Participating Physicians under
     the Plans.  GBIPA further agrees that in no event, including but not
     limited to non-payment by PHS or GBIPA, PHS or GBIPA insolvency, or breach
     of this Agreement shall GBIPA or Participating Physicians or Consultant
     Physicians charge, collect a deposit from, seek compensation, remuneration
     or reimbursement from or have any recourse against a Member, other than PHS
     acting on a Member's behalf, for Covered Services rendered pursuant to this
     Agreement.  This provision shall not prohibit collection by Participating
     Physicians of copayments or supplemental charges made in accordance with
     Programs.  This Section 3.8 shall survive termination of this Agreement
     regardless of the cause giving rise to termination and shall be construed
     to be for the benefit of Members.

3.9  Delegation.  GBIPA and PHS agree that GBIPA may delegate to PHS the
     ----------                                                         
     performance of such of its responsibilities as GBIPA may determine from
     time to time.

3.10 Bonus Pool.  PHS shall establish a bonus pool in connection with its
     ----------                                                          
     gatekeeper model plan equal to 15% of the annual aggregate capitation
     payments to Participating Physicians who receive capitation payments in
     respect of IPA Members who have selected a Participating Physician as their
     Primary Care Physician in such Program.  Interest earnings on amounts held
     in the bonus pool shall be the property of PHS and neither GBIPA nor
     Participating Physicians shall assert any claims to such amounts.  Amounts
     in the bonus pool shall be distributed by PHS to Eligible Participating
     Physicians no more than 75 days following the end of each Health Care Year.
     If PHS fails to distribute the bonus pool within 15 days following written
     notice by GBIPA that PHS is in default of the distribution provisions of
     the preceding sentence. PHS shall pay interest for each day elapsed
     thereafter on amounts owed as bonus pool distributions at a rate equal to
     the Citibank prime rate.

3.11 Administrative Services.  GBIPA shall be liable for its administrative
     -----------------------                                               
     costs, including the costs of all insurance deemed necessary or advisable
     to it; provided, however, that PHS shall provide to GBIPA, upon GBIPA's
     request and without additional charge, administrative support generally
     provided as of the date hereof and administrative support similar in scope
     to the administrative support given by PHS to other provider organizations
     with which PHS contracts for health care services.  Additional support
     services shall be provided by PHS upon GBIPA's request.  GBIPA shall pay
     PHS the reasonable out of pocket cost of providing such services and no
     services shall be performed without GBIPA's prior approval of the
     compensation arrangements.

                             ARTICLE IV - PROGRAMS
                             ---------------------

4.1  Program Design and Introduction.  PHS shall have sole authority over
     -------------------------------                                     
     matters relating to Program design, participation of a Participating
     Physician in PHS Programs, introduction of new Programs and modification or
     elimination of existing Programs, including without limitation,
     utilization, referral, quality assessment, reimbursement and reimbursement
     protocols relating to such Programs.  PHS shall consult with the Advisory
     Committee in the material design features of Programs and shall use its
     best efforts to incorporate the recommendations of the Advisory Committee
     into final Program design as are reasonably necessary or desirable in the
     Advisory Committee's view and that do not adversely affect the
     administration, financial or operational aspects of such Program.

                                       6
<PAGE>
 
4.2  Participation in Programs.  Except (i) as waived by PHS, which waiver PHS
     -------------------------                                                
     shall not unreasonably withhold or delay and (ii) for Participating
     Physicians who did not elect to participate in the Passport Program at the
     time of its inception, Participating Physicians are required to participate
     in all Programs and PHS may not exclude any Participating Physician except
     as set forth below.  GBIPA agrees to sanction or terminate in accordance
     with the Physician Agreement, Office Manual, or otherwise, any
     Participating Physician who notifies GBIPA or PHS that he or she will not
     participate in a Program or who does not accept Members enrolled in one or
     more Programs.  Notwithstanding the foregoing, PHS may select, after
     consultation with GBIPA, a subset of Participating Providers for
     governmental Programs if, in its reasonable discretion, PHS believes that
     fewer than all Participating Providers should be permitted to participate
     in a such governmental Program, or upon GBIPA's consent, which consent
     shall not be reasonably withheld for all other Programs, if PHS is
     requested to reduce the size of its panel of participating Providers for an
     employer group of 1,000 or more eligible Members.  Notwithstanding the
     foregoing, PHS may terminate a Participating Physician from participation
     in all Programs in accordance with the due process protocols set forth in
     the Office Manual.

                            ARTICLE V - COMPENSATION
                            ------------------------

5.1  Capitation System.  Except as set forth in Section 5.6 hereof or except as
     -----------------                                                         
     specifically provided and agreed to by GBIPA in connection with certain
     Programs, PHS shall allocate to GBIPA a monthly capitation from which GBIPA
     shall compensate Participating Physicians, Consultants (in case of Covered
     Services rendered to GBIPA Members), and also, in cases of Medical
     Emergency or upon prior approval by PHS, non-Participating Physicians and
     providers, for Covered Services which are rendered to GBIPA Members except
     (i) Covered Services pursuant to Programs which are paid directly by the
     employer; and (ii) Covered Services pursuant to Programs for which PHS pays
     participating Physicians directly (through capitation, fee for service or
     any other payment methodology).  GBIPA agrees that, together with PHS, and
     upon PHS's request, it will consider special promotional capitation
     arrangements for employer groups of 1,000 or more eligible members.  Except
     as otherwise provided herein, it is understood and agreed that GBIPA shall
     be solely responsible for compensating the foregoing health care providers
     from the capitation payments allocated to it for such Covered Services, and
     GBIPA shall not look to PHS for any additional compensation.  The
     capitation payments payable hereunder are set forth in Exhibit C.

     (a) GBIPA shall not be liable for the costs of rendering Contracted
         Services or for Covered Services for which PHS pays Participating
         Physicians directly, which Services shall be paid by the Contracted
         Service providers or PHS, as the case may be, directly and not charged
         against capitation payments held in the risk sharing fund.

5.2  Payments Administered by PHS.  The amount allocated as the monthly
     ----------------------------                                      
     capitation for Covered Services pursuant to Section 5.1 shall be held and
     administered by PHS for the purpose of enabling GBIPA to discharge its
     payment obligations as set forth in Section 5.1.  PHS shall act as GBIPA's
     agent for purposes of making all payments and distributions to
     participating Physician and Consultant Physicians (in cases of Covered
     Services rendered to GBIPA Members).  GBIPA agrees that the payments made
     by PHS as GBIPA's agent hereunder shall be deducted from amounts allocated
     to GBIPA as capitation payments.  Payments shall be made irrespective of
     whether actual payments made pursuant to this paragraph exceed the amounts
     allocated to GBIPA as capitation payments.  Subject to Section 5.4,
     payments shall be made in accordance with the following:

     (a) Compensation for Participating Physicians and Consultants shall be
         calculated on the basis of the lesser of (i) the Physician's or
         Consultant Physician's billed charges, and (ii) the reimbursement
         schedules agreed to by PHS and GBIPA (through the reimbursement
         committee) from time to time or an actuarially determined capitation
         amount.  The 

                                       7
<PAGE>
 
         administrative guidelines for reimbursement of fees shall be maintained
         by PHS. GBIPA agrees that the aggregate fees for 1996 shall not exceed
         the aggregate fees that were payable in 1995.

     (b) Participating Physicians shall be paid within two (2) months of the
         receipt by PHS of a properly submitted bill for Covered Services,
         except for claim payments subject to claims recovery through
         coordination of benefits (C.O.B.).  Participating Physicians shall only
         be paid for bills for Covered Services received by PHS within ninety
         (90) days of the date of service, unless such bills have been subject
         to claims recovery through C.O.B., basic reparation of benefits under
         an automobile no-fault policy, worker's compensation or subrogation
         activity.  For Covered Services involving C.O.B., GBIPA shall be liable
         to pay Participating Physicians only for bills received within twelve
         (12) months of the date of service.  Participating Physicians may not
         bill Members for bills for Covered Services which are not submitted in
         accordance with this clause (b).

5.3  Withhold and Reserve Provision.  PHS may establish a withhold provision for
     ------------------------------                                             
     a percentage of the compensation payable to GBIPA pursuant to Section 5.1
     on behalf of Participating Physicians for Covered Services, to be held in a
     risk fund, it being understood and agreed that the amounts retained shall
     be applied to offset the amounts by which the actual costs of Covered
     Services rendered to GBIPA Members exceed budgeted amounts for such Health
     Care Year.  PHS may not change the withhold amounts without GBIPA's
     consent; provided, however, that if overutilization is projected to result
     in deficit balances in the withhold account at the end of the Health Care
     Year, GBIPA and PHS shall adjust the withhold amounts to correct the
     anticipated deficit in the withhold amount.  Actual withhold amounts may
     vary according to category of services provided, Program and Participating
     Physician, as determined by GBIPA; provided, however, that the withhold may
     not be reduced below 15%.  The withhold amount shall be initially
     established at 20%, but may be reduced to no less than 15% upon request of
     GBIPA.  PHS and GBIPA shall, at regular intervals, review the utilization
     and costs of such services.  Amounts withheld or reserved in the risk funds
     shall be allocated and distributed at the end of each Health Care Year or
     earlier as reasonably agreed to by the parties.  Amounts that remain in the
     risk sharing fund due to the withhold provision at the end of each Health
     Care Year shall be made available to GBIPA not more than 75 days following
     the end of each Health Care Year for distribution to Participating
     Physicians.  If PHS fails to distribute the withhold amount within 15 days
     following written notice by GBIPA that PHS is in default of the
     distribution provisions of the preceding sentence, PHS shall pay interest
     for each day elapsed thereafter on amounts owed as withhold distributions
     at a rate equal to the Citibank prime rate.  Amounts remaining in the
     withhold fund at the end of a  Health Care Year shall be distributed in
     accordance with GBIPA's instructions, potentially including a variable risk
     return in 1996.  Amounts earned on funds held in the withhold account shall
     be the property of PHS and neither GBIPA nor Participating Physicians shall
     assert any claims to such amounts.  Amounts payable to Participating
     Physicians pursuant to Section 5.6 (Self Funded Payers, Direct Payments)
     shall not be subject to this Section 5.4. Commencing on January 1, 1997,
     PHS shall, at GBIPA's request, implement a variable withhold for payments
     made to individual Participating Physicians pursuant to Section 5.3.  The
     percent level of withhold for specific programs and the methodology for a
     variable withhold program shall be subject to GBIPA's consent.

     for the percent of such Excess Payments as set forth on Exhibit C and shall
     repay such amounts within 30 days after notice from PHS of the extent of
     the Excess Payment.  GBIPA has the right to increase the percentage of
     compensation withheld to such levels GBIPA may deem necessary to preserve
     GBIPA's fiscal integrity.

5.5  Intra-Network Payments.  PHS shall make payments as GBIPA's agent from
     ----------------------

     GBIPA Members by Non-GBIPA Participating

     providers. PHS will pay Participating Physicians for Covered Services
     rendered to Members who are not GBIPA Members in accordance with Section
     5.2; such payments on behalf of Members who are not GBIPA Members shall not
     be charged against the capitation amount allocated to GBIPA. All payments
     made hereunder will be subject to the withhold provisions set forth in
     Section 5.3.

     -----------------------------------                                        
     employer group self-funds its claims expense or Programs in which PHS
     elects to pay Participating Physicians on a fee for service basis without
     regard to capitation, PHS shall compensate Participating Physicians in
     accordance with the fee schedule then in effect.  For Programs in which
     Participating Physicians are capitated directly, PHS shall compensate such
     Participating Physicians in accordance with Exhibit C.

5.7  Forms; Cooperation.
     ------------------ 
 
     (a)  GBIPA shall arrange for Participating Physicians to bill PHS for

          forms shall specify the Covered Services provided and shall include
          all of the statistical and descriptive medical, diagnostic and patient
          data together with identifying information required by PHS.

     (b)  GBIPA shall arrange for Participating Physicians to cooperate with and
          participate in PHS programs for coordination of benefits with other
          health care plans or any other permitted methods of third party
          recovery.  Such programs include, but are not limited to, the
          following:

          (i)    Assisting Members with required forms.

          (ii)   Where duplicate coverage exists and the Program appears to be
                 secondary coverage, notifying PHS and for ninety (90) days
                 seeking payment from the other health care plan, before seeking
                 payment from PHS or self funded payer.

          (iii)  Where other plan(s) must pay their benefits before the benefits
                 of the applicable Program, accepting as PHS's payment, the
                 lesser of the payment determined in accordance with Section 5.2
                 (a) and the amount equal to the provider's usual charges for
                 Covered Services, reduced by amounts paid by other plan(s) (or
                 to be paid in the case of Medicare, Worker's Compensation Law,
                 occupational disease or any similar law).

5.8  Coverage Questions.  PHS shall make timely payment to Participating
     ------------------                                                 
     Physicians as provided in Section 5.3 unless prior to the expiration of the
     period set forth therein PHS notifies the Participating Physician in
     writing that additional information is required or that a coverage question
     (including without limitation, a question relating to coordination of
     benefits or pre-existing conditions) exists.  Such notice shall specify any
     additional information required and shall describe the nature of the
     coverage question.  PHS shall endeavor in good faith to promptly resolve
     coverage questions, and shall make payment, if appropriate, promptly after
     coverage questions are resolved but in no case later than ninety (90) days
     after a submission of all required information.  In the case of requests
     for additional information, the claims shall be paid within the thirty (30)
     days of receipt of all requested information.

5.9  Subrogation.  In the event a Member is injured by an act or omission of a
     -----------                                                              
     participating Physician in connection with the rendering of Covered
     Services hereunder, PHS may elect to pursue its subrogation rights, if any,
     against the potentially responsible participating Physician.  PHS shall
     make payment to the Physician in accordance with this Agreement while
     pursuing those rights.

     payable out of the payments made pursuant to Section 5.1 hereof, in monthly
     installments due no later than the fifth working day of each month.  GBIPA
     shall endeavor to establish the annual administrative fee prior to the
     commencement of a Health Care Year, and shall notify PHS of the amounts of
     each monthly payment; provided, however, that the fees may be established
     and/or changed in the GBIPA Board of Directors' sole discretion no less
     than 30 days prior to the effective date of the change.  The annual
     administrative fee shall be such amount as determined by GBIPA to be
     reasonable compensation for its administrative services.

     and federal privacy and confidentiality requirements, to each other upon
     request without cost in order to determine that the content of such report
     and the quality of care rendered are acceptable, as well as for peer

     legal issues, claims or actions may arise that involve or could potentially
     involve the parties and their respective employees and agents.  The parties
     further recognize the importance of cooperating with each other in good
     faith when such issues, claims or actions arise to the extent that such
     cooperation does not violate any applicable laws, cause breach of any

10.11 Exclusivity.
      ----------- 

      (a)  Except as provided in Sections 10.11(b) and (c) below and in Section
           3.8 hereof, (i) GBIPA agrees that neither it, not any subsidiary of
           GBIPA, shall contract with any other health maintenance organization
           or preferred provider organization or any other entity that competes
           or intends to compete with PHS in the Service Area, and (ii) PHS
           agrees that neither it, nor any subsidiary of PHS shall contract with
           any individual Participating Physician or any individual practice
           association (other than GBIPA), physician hospital organization,
           medical service organization or other organization providing
           physician services for Covered Services in the Service Area relating
           to commercial managed care products, including administrative
           services only and point of service products, or other non-
           governmental managed care products. Notwithstanding the foregoing,
           either party may contract with another party during the 120 day
           period immediately preceding the Termination Date, unless the parties
           have entered into a new agreement for a subsequent term.

      (b)  GBIPA shall terminate any Participating Physicians whose principal

           PHS's sole discretion.

           providers whose principal office is outside the Service Area; and

           Area, including without limitation, networks that have a geographic
           presence both inside and outside the Service Area, but whose presence
           is substantially outside the Service Area.

10.12 Compliance with Law; Policy Changes.  During the term of this Agreement,
      -----------------------------------                                     
      PHS and GBIPA agree to incorporate any changes required by law, regulation
      or policy of NCQA.  To the extent additional national accreditation bodies
      (such as JCAH) develop their own accreditation requirements, and these
      requirements have a material impact on the ability of PHS to pursue new
      business or retain current business, GBIPA and PHS agree to work together
      in developing additional policy changes. GBIPA shall take all acts or
      actions necessary to permit compliance by PHS with applicable law as well
      as accreditation programs conducted by the NCQA, or another entity
      performing similar functions. PHS will consult with the Advisory Committee
      with respect to future actions to be taken to permit compliance as set
      forth in the preceding sentence.

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

     contract with PHS.

     protocols (collectively, "Rules") adopted by PHS in furtherance of Article
     II hereof; provided, however, that no amendments or modifications to the
     Rules shall be made without IPA's consent which will have the effect of (i)
     adversely affecting any rights or remedies of IPA as against PHS or any
     Participating Physician; (ii) adding to, increasing or adversely affecting
     (as to IPA) any obligations of IPA to PHS or to any Participating
     Physician; or (iii) amending or modifying any sanctions, penalties or

     process for sanctioning, penalizing or terminating any Participating
     Physician or appealing decisions or terminating any Participating Physician
     or appealing the decisions with respect thereto.  IPA shall use its best

     Physician's supervision, which could result in (i) the suspension or loss
     of any license or certification; (ii) the impairment for any other reason
     of such Participating Provider's ability to render the Covered Services
     required under this Agreement; (iii) the imposition of any sanctions
     against such Participating Physician; (iv) any malpractice claim filed
     against a Participating Physician; (v) any compromise, settlement, or
     judgment of such a claim and the terms and conditions thereof; (vi) any
     revocation, suspension, modification, restriction or other change in status
     of a Participating Physician's medical staff privileges at any hospital or
     other health care facility; or (vii) any investigation of a Participating
     Physician by any governmental agency or board or any medical association
     relating to a disciplinary cause or reason.

3.8  Disclosure of Information and Records.  Subject to applicable laws
     -------------------------------------                             
     regarding confidentiality, IPA hereby authorizes PHS to release to any
     party any and all information, records, summaries of records and
     statistical reports specific to the IPA and/or any Participating
     Physicians, including but not limited to, utilization profiles, encounter

     Covered Services provided to Members by Participating Physicians under the
     Plans.  IPA further agrees that in no event, including but not limited to
     non-payment by PHS or IPA, PHS or IPA insolvency, or breach of this
     Agreement shall IPA or Participating Physicians or Consultants (as defined
     in Section 1.3(i)) charge, collect a deposit from, seek compensation,
     remuneration or reimbursement from or have any recourse against a Member,
     other than PHS acting on a Member's behalf, for Covered Services rendered
     pursuant to this Agreement.  This provision shall not prohibit collection
     by Participating Physicians of copayments or supplemental charges made in
     accordance with Programs.  This Section 3.10 shall survive termination of
     this Agreement regardless of the cause giving rise to termination and shall
     be construed to be for the benefit of Members.

          hereof, one hundred percent (100%) of the surplus shall be deemed to
          be Surplus Amounts hereunder.

     (iii)  The Physician and Other Fund.  In the event that payments in respect
            ----------------------------                                        
          of Covered Services rendered to IPA Members other than the Covered
          Services described in clauses (i), (ii) and (iv) of this Section 5.2,
          exceed amounts budgeted therefor in accordance with Section 5.1
          hereof, one hundred percent (100%) of the deficit shall be deemed to
          be Excess Payments hereunder.  In the event that payments in respect
          of Covered Services (except as provided in clauses (i), (ii) and (iv),
          rendered to IPA Members are less than amounts budgeted therefor in

          surplus shall be deemed Surplus Amounts hereunder.

     (iv) The Pharmaceutical Fund.  In the event that payments in respect of
          -----------------------                                           
          pharmaceutical related Covered Services rendered to IPA Members exceed
          amounts budgeted therefor in accordance with Section 5.1 hereof, fifty
          percent (50%) of the deficit shall be deemed to be Excess Payments

          related Covered Services rendered to IPA Members are less than amounts
          budgeted therefor in accordance with Section 5.1 hereof, fifty percent
          (50%) of the surplus shall be deemed to be Surplus Amounts hereunder.

5.3. Payments Administered by PHS.  The amount allocated as the monthly
     ----------------------------                                      
     capitation for Covered Services pursuant to Section 5.2 shall be held and
     administered by PHS for the purpose of enabling IPA to discharge its
     payment obligations as set forth in Section 5.2.  PHS shall act as IPA's
     agent for purposes of making all payments and distributions to
     Participating Physicians, Consultants, Non-IPA Participating Physicians and
     other health care providers as set forth in Section 5.2 (in cases of
     Covered Services rendered to IPA Members).  IPA agrees that the payments
     made by PHS as IPA's agent hereunder shall be deducted from amounts
     allocated to IPA as capitation payments.  Payments shall be made
     irrespective of whether actual payments made pursuant to this paragraph
     exceed the amounts allocated to IPA as capitation payments.  Subject to
     Section 5.5, payments shall be made in accordance with the following:

     (a) Compensation for Participating Physicians, Consultants and Non-IPA
         Participating Providers shall be calculated on the basis of the lesser
         of the Physician's, Consultant's or Non-IPA Participating Provider's
         billed charges, and (i) in the case of Participating Physicians, the
         reimbursement schedules agreed to by PHS and IPA from time to time or
         an actuarially determined capitation amount, and (ii) in the case of
         Consultants, Non-IPA Participating Physicians, and other health care
         providers, the PHS reimbursement schedule in effect from time to time.
         The administrative guidelines for reimbursement of fees shall be
         maintained by PHS.

     (b) Participating Physicians shall be paid within two (2) months of the
         receipt by PHS of a properly submitted bill for Covered Services,
         except for claim payments subject to claims recovery through
         coordination of benefits (C.O.B.).  Participating Physicians shall only
         be paid for bills for Covered Services received by PHS within 90 days
         of the date of service, unless such bills have been subject to claims
         recovery through C.O.B., basic reparation of benefits under an
         automobile no-fault policy, worker's compensation or subrogation
         activity.  For Covered Services involving C.O.B., IPA shall be liable
         to pay Participating Physicians only for bills received within 18
         months of the date of service.  Participating 

                                       7
<PAGE>
 
         Physicians may not bill Members for bills for Covered Services which
         are not submitted in accordance with this Section 5.3 (b).

5.4. Withhold and Reserve Provision.  PHS may establish a withhold provision for
     ------------------------------                                             
     a percentage of the compensation payable to IPA pursuant to Section 5.2 on
     behalf of Participating Physicians for Covered Services, to be held in a
     risk fund, it being understood and agreed that the amounts retained shall
     be applied to offset the amounts by which the actual costs of Covered
     Services rendered to IPA Members exceed budgeted amounts for the year.
     Actual withhold amounts may vary according to Program and Participating
     Physician.  The percent level of withhold for specific programs and the
     methodology for a variable withhold program shall be subject to IPA
     consent.  PHS and IPA shall, at regular intervals, review the utilization
     and costs of such services.  PHS has the right to increase the percentage
     of compensation withheld to such levels as PHS may deem necessary to
     preserve IPA's fiscal integrity; provided, however that any increase is
     subject to IPA's consent, which consent shall not be unreasonably withheld.
     Amounts earned on funds held in the withhold account shall be the property
     of PHS and neither IPA nor Participating physicians shall assert any claims
     to such amounts.

5.5  Excess Payments and Surplus Amounts.  If PHS makes Excess Payments, IPA
     -----------------------------------                                    
     shall be liable to PHS for such Excess Payments and shall repay such
     amounts within 30 days after notice from PHS of the extent of the Excess
     Payment.  If there are Surplus Amounts, PHS shall allocate such Surplus
     Amounts to Participating Physicians in accordance with instructions from
     IPA and shall pay such Surplus Amounts to Participating Physicians not more
     than 75 days following the end of the year; provided, however, that prior
     to making any payments from surplus Amounts, Surplus Amounts shall be
     applied first to reduce or eliminate Excess Payments, if any, in one or
     more Funds and shall only be payable as provided in this Section 5.5 if
     there are no Excess Payments outstanding in any Fund.

5.5  Intra-Network Payments.  PHS shall make payments as IPA's agent from
     ----------------------                                              
     capitation amounts allocated to IPA for Covered Services rendered to IPA
     Members by Non-IPA Participating Physicians, Consultants or health care
     providers.   PHS will pay Participating Physicians for Covered Services
     rendered to Members who are not IPA Members in accordance with Section 5.3;
     such payments on behalf of Members who are not IPA Members shall not be
     charged against the capitation amount allocated to IPA.  All payments made
     hereunder will be subject to the withhold provisions set forth in Section
     5.4.

5.6  Self Funded Payers; Direct Payments.  For Programs with respect to which an
     -----------------------------------                                        
     employer group self-funds its claims expense or Programs in which PHS
     elects to pay Participating Physicians on a fee for service basis without
     regard to capitation, PHS shall compensate Participating Physicians in
     accordance with the PHS fee schedule then in effect.

5.7  Forms; Cooperation.

     (a)  IPA shall arrange for Participating Physicians to bill PHS for Covered
          Services provided to Members on forms as reasonably specified by PHS.
          These forms shall specify the Covered Services provided and shall
          include all of the statistical and descriptive medical, diagnostic and
          patient data together with identifying information required by PHS.

     (b)  IPA shall arrange for Participating Physicians to cooperate with and
          participate in PHS programs for coordination of benefits with other
          health care plans or any other permitted methods of third party
          recovery.  Such programs include, but are not limited to, the
          following:

               secondary coverage, notifying PHS and for ninety (90) days
               seeking payment from the other health care plan, before seeking
               payment from PHS or self funded payer.

          (iii)  Where other plan(s) must pay their benefits before the benefits
               of the applicable Program, accepting as PHS's payment, the lesser
               of the payment determined in accordance with Section 5.3 (a) and
               the amount equal to the provider's usual charges for Covered
               Services, reduced by amounts paid by other plan(s) (or to be paid
               in the case of Medicare, Worker's Compensation Law, occupational
               disease or any similar law).

5.8  Coverage Questions.  PHS shall make timely payment to Participating
     ------------------

     the period set forth therein, PHS notifies the Participating Physician in
     writing that additional information is required or that a coverage question
     (including without limitation, a question relating to coordination of
     benefits or pre-existing conditions) exists.  Such notice shall specify any
     additional information required and shall describe the nature of the
     coverage question.  PHS shall endeavor in good faith to promptly resolve
     coverage questions, and shall make payment, if appropriate, promptly after
     coverage questions are resolved but in no case later than ninety (90) days
     after a submission of all required information.  In the case of requests
     for additional information, the claims shall be paid within 30 days of
     receipt of all requested information.

     Participating Physician in connection with the rendering of Covered
     Services hereunder, PHS may elect to pursue its subrogation rights, if any,
     against the potentially responsible Participating Physician. PHS shall make

     those rights.

     reports, data, data formats, financial information and other documents or
     information pertaining to the other or any related company which are
     provided, made available, or otherwise disclosed to the other pursuant to

contractors.  None of the provisions of this Agreement are intended to create
nor shall be construed to create a partnership, or joint venture relationship
between the parties. Except as to payment procedures for which PHS shall act as
IPA's agent hereunder, neither party hereto nor any of their respective

                  ARTICLE VIII - INDEMNIFICATION AND INSURANCE
                  --------------------------------------------

8.1. Physician Insurance.  IPA shall require all of its Participating Physicians
     -------------------                                                        
     and all Consultants to whom a Member is referred by a Participating
     Physician to maintain professional liability insurance acceptable to PHS in
     an amount not less than $1,000,000 per incident and $3,000,000 aggregate to

     Agreement.

8.2. Cooperative Defense.  The parties recognize that, during the term of this

     Agreement and for some period thereafter, certain risk management issues,
     legal issues, claims or actions may arise that involve or could potentially
     involve the parties and their respective employees and agents.  The parties
     further recognize the importance of cooperating with each other in good
     faith when such issues, claims or actions arise to the extent that such
     cooperation does not violate any applicable laws, cause breach of any
     duties created by any policies of insurance, or otherwise compromise the
     confidentiality of communications of information regarding the issues,
     claims or actions.  The parties shall cooperate in good faith, using their
     best efforts, to address such risk management and claims handling issues in

     commencing on January 1, 1997, and shall terminate on December 31, 1997.

     the commencement of any proceedings under the bankruptcy or insolvency law
     by or against such other party.  This Agreement may also be terminated upon

9.2  Termination of Participating Physicians.  A Participating Physician
     ---------------------------------------                            
     terminating his relationship with IPA will also terminate his participation
     in the Programs. A termination by a Participating Physician shall not be
     deemed a termination of this Agreement, which may only be terminated
     pursuant to Section 9.1.  PHS may terminate a Participating Physician in
     all Programs subject to the due process protocols set forth in the Office
     Manual.  Termination of a Participating Physician's participation in
     Programs shall not be deemed a termination of the Physician Agreement
     without further action on the part of IPA.

9.3  Effect of Termination.
     --------------------- 

     (a) Upon the effective termination of this Agreement, all rights and
         obligations of the parties under this Agreement shall immediately
         cease; provided, however, that IPA shall remain responsible for
         providing Covered Services under the terms of this Agreement to Members
         who are under the care of Participating Physicians at the time of such
         termination through the period for which premiums have been paid (but
         in no event more than 90 days, except that if a Member is hospitalized
         at the time of termination, until the Member is discharged), unless PHS
         makes reasonable and medically appropriate provision for the assumption
         of such services by another provider.  PHS shall compensate
         Participating Physicians for those Covered Services, for which premium
         was received, rendered prior to and following the termination date (as
         provided in this Section 9.3(a)) pursuant to the PHS/IPA fee schedule
         in effect at such time.  In the event this Agreement is terminated due
         to the last sentence of Section 9.1, the non-defaulting party shall be
         entitled to pursue all legally available remedies consistent with
         Section 10.4 herein, and damages arising out of such breach.

     (b) Upon termination, PHS is authorized to notify Members, prospective
         Members and Participating Physicians, and other persons and entities
         whom it deems to have an interest herein of such termination.

     necessary to enable IPA to discharge its obligations hereunder.  IPA shall

     in Section 1.3(i)) charge, collect a deposit from, seek compensation,
     remuneration or reimbursement from or have any recourse against a Member,

     from which IPA shall compensate Participating Physicians, Consultants, Non-
     IPA Participating Providers and also, in cases of Medical Emergency or upon

          amounts budgeted therefor in accordance with Section 5.1 hereof, fifty
          percent (50%) of the deficit over the Corridor shall be deemed to be
          Excess Payments hereunder.  In the event that payments in respect of
          hospital in-patient Covered Services rendered to IPA Members are less
          than amounts budgeted therefor in accordance with Section 5.1 hereof,
          fifty percent (50%) of the surplus under the Corridor shall be deemed
          to be Surplus Amounts hereunder.

     (ii)   The Out-Patient Hospital Fund.  In the event that payments in 
            -----------------------------

            Surplus Amounts hereunder.

     (iii)  The Physician and other Fund.  In the event that payments in respect
            ----------------------------                                        
            of Covered Services rendered to IPA Members other than the Covered
            Services described in clauses (i), (ii) and (iv) of this Section
            5.2, exceed amounts budgeted therefor in accordance with Section 5.1
            hereof, one hundred percent (100%) of the deficit shall be deemed to
            be Excess Payments hereunder. In the event that payments in respect
            of Covered Services (except as provided in clauses (i), (ii) and
            (iv) rendered to IPA Members are less than amounts budgeted therefor
            in accordance with Section 5.1 hereof, one hundred percent (100%) of
            the surplus shall be deemed Surplus Amounts hereunder.

     (iv)   The Pharmaceutical Fund.  In the event that payments in respect of
            -----------------------

            less than amounts budgeted therefor in accordance with Section 5.1
            hereof, fifty percent (50%) of the surplus shall be deemed to be
            Surplus Amounts hereunder.

5.3. Payments Administered by PHS.  The amount allocated as the monthly
     ----------------------------                                      
     capitation for Covered Services pursuant to Section 5.2 shall be held and
     administered by PHS for the purpose of enabling IPA to discharge its
     payment obligations as set forth in Section 5.2.  PHS shall act as IPA's
     agent for purposes of making all payments and distributions to
     Participating Physicians, Consultants, Non-IPA Participating Physicians and
     other health care providers as set forth in Section 5.2 (in cases of
     Covered Services rendered to IPA Members).  IPA agrees that the payments
     made by PHS as IPA's agent hereunder shall be deducted from amounts
     allocated to IPA as capitation payments.  Payments shall be made
     irrespective of whether actual payments made pursuant to this paragraph
     exceed the amounts allocated to IPA as capitation payments.  Subject to
     Section 5.5, payments shall be made in accordance with the following:

     (a) Compensation for Participating Physicians, Consultants and Non-IPA
         Participating Providers shall be calculated on the basis of the lesser
         of the Physician's, Consultant's or Non-IPA Participating Provider's
         billed charges, and (i) in the case of Participating
         Physicians,respect the reimbursement schedules agreed to by PHS and IPA
         from time to time or an actuarially determined capitation amount, and
         (ii) in the case of Consultants, Non-IPA Participating Physicians, and
         other health care providers, the PHS reimbursement schedule in effect
         from time to time.  The administrative guidelines for reimbursement of
         fees shall be maintained by PHS.

     (b) Participating Physicians shall be paid within two (2) months of the
         receipt by PHS of a properly submitted bill for Covered Services,
         except for claim payments subject to claims recovery through
         coordination of benefits (C.O.B.).  Participating Physicians shall only
         be paid for bills for Covered Services received by PHS within 90 days
         of the date of service, unless such bills have been subject to claims
         recovery through C.O.B., basic reparation of benefits under an
         automobile no-fault policy, worker's compensation or subrogation
         activity.  For Covered Services involving C.O.B., IPA shall be liable
         to pay Participating Physicians only for bills received within 18
         months of the date of service.  Participating 

                                       7

         Physicians may not bill Members for bills for Covered Services which
         are not submitted in accordance with this Section 5.3 (b).

5.4. Withhold and Reserve Provision.  PHS may establish a withhold provision for
     ------------------------------                                             
     a percentage of the compensation payable to IPA pursuant to Section 5.2 on
     behalf of Participating Physicians for Covered Services, to be held in a
     risk fund, it being understood and agreed that the amounts retained shall
     be applied to offset the amounts by which the actual costs of Covered
     Services rendered to IPA Members exceed budgeted amounts for such year.
     Actual withhold amounts may vary according to Program and Participating
     Physician.  The percent level of withhold for specific programs and the
     methodology for a variable withhold program shall be subject to IPA
     consent, which consent shall not be unreasonably withheld.  PHS and IPA
     shall, at regular intervals, review the utilization and costs of such
     services.  PHS has the right to increase the percentage of compensation
     withheld to such levels PHS may deem necessary to preserve IPA's fiscal
     integrity; provided, however that any increase is subject to IPA's consent,
     which consent shall not be unreasonably withheld.  Amounts earned on funds
     held in the withhold account shall be the property of PHS and neither IPA
     nor Participating Physicians shall assert any claims to such amounts.

5.5  Excess Payments and Surplus Amounts.  If PHS makes Excess Payments, IPA
     -----------------------------------                                    
     shall be liable to PHS for such Excess Payments and shall repay such
     amounts promptly upon demand by PHS. If there are Surplus Amounts, PHS
     shall allocate such Surplus Amounts to Participating Physicians in
     accordance with instructions from IPA and shall pay such Surplus Amounts to
     Participating Physicians not more than 75 days following the end of the
     year; provided, however, that prior to making any payments from Surplus
     Amounts, Surplus Amounts shall be applied first to reduce or eliminate
     Excess Payments, if any, and shall be payable as provided in this Section
     5.5 only if there are no Excess Payments outstanding in any Fund.

5.6  Intra-Network Payments.  PHS shall make payments as IPA's agent from
     ----------------------                                              
     capitation amounts allocated to IPA for Covered Services rendered to IPA
     Members by Non-IPA Participating Physicians, Consultants or health care
     providers.   PHS will pay Participating Physicians for Covered Services
     rendered to Members who are not IPA Members in accordance with Section 5.3;
     such payments on behalf of Members who are not IPA Members shall not be
     charged against the capitation amount allocated to IPA.  All payments made
     hereunder will be subject to the withhold provisions set forth in Section
     5.4.

5.7  Self Funded Payers; Direct Payments.  For Programs with respect to which an
     -----------------------------------                                        
     employer group self-funds its claims expense or Programs in which PHS
     elects to pay Participating Physicians on a fee for service basis without
     regard to capitation, PHS shall compensate Participating Physicians in
     accordance with the PHS fee schedule then in effect.

5.8  Forms; Cooperation.

          include all of the statistical and descriptive medical, diagnostic and
          patient data together with identifying information required by PHS.

     (b)  IPA shall arrange for Participating Physicians to cooperate with and
          participate in PHS programs for coordination of benefits with other
          health care plans or any other permitted methods of third party
          recovery.  Such programs include, but are not limited to, the
          following:

          (i)    Assisting Members with required forms.

                 secondary coverage, notifying PHS and for ninety (90) days
                 seeking payment from the other health care plan, before seeking
                 payment from PHS or self funded payer.

          (iii)  Where other plan(s) must pay their benefits before the benefits
                 of the applicable Program, accepting as PHS's payment, the
                 lesser of the payment determined in accordance with Section 5.3
                 (a) and the amount equal to the provider's usual charges for
                 Covered Services, reduced by amounts paid by other plan(s) (or
                 to be paid in the case of Medicare, Worker's Compensation Law,
                 occupational disease or any similar law).

5.9  Coverage Questions.  PHS shall make timely payment to Participating
     ------------------                                                 
     Physicians as provided in Section 5.3 unless, prior to the expiration of
     the period set forth therein, PHS notifies the Participating Physician in
     writing that additional information is required or that a coverage question
     (including without limitation, a question relating to coordination of
     benefits or pre-existing conditions) exists.  Such notice shall specify any
     additional information required and shall describe the nature of the
     coverage question.  PHS shall endeavor in good faith to promptly resolve
     coverage questions, and shall make payment, if appropriate, promptly after
     coverage questions are resolved but in no case later than 90 days after a
     submission of all required information.  In the case of requests for
     additional information, the claims shall be paid within 30 days of receipt
     of all requested information.

     -----------                                                              
     Participating Physician in connection with the rendering of Covered
     Services hereunder, PHS may elect to pursue its subrogation rights, if any,
     against the potentially responsible Participating Physician. PHS shall make
     payment to the Physician in accordance with this Agreement while pursuing
     those rights.

                             ARTICLE VI  - RECORDS

     reports, data, data formats, financial information and other documents or
     information pertaining to the other or any related company which are
     provided, made available, or otherwise disclosed to the other pursuant to

contractors.  None of the provisions of this Agreement are intended to create
nor shall be construed to create a partnership, or joint venture relationship
between the parties. Except as to payment procedures for which PHS shall act as
IPA's agent hereunder, neither party hereto nor any of their respective

                  ARTICLE VIII - INDEMNIFICATION AND INSURANCE
                  --------------------------------------------

8.1. Physician Insurance.  IPA shall require all of its Participating Physicians
     -------------------                                                        
     and all Consultants to whom a Member is referred by a Participating
     Physician to maintain professional liability insurance acceptable to PHS in
     an amount not less than $1,000,000 per incident and $3,000,000 aggregate to

     Agreement.

8.2. Cooperative Defense.  The parties recognize that, during the term of this

     Agreement and for some period thereafter, certain risk management issues,
     legal issues, claims or actions may arise that involve or could potentially
     involve the parties and their respective employees and agents.  The parties
     further recognize the importance of cooperating with each other in good
     faith when such issues, claims or actions arise to the extent that such
     cooperation does not violate any applicable laws, cause breach of any
     duties created by any policies of insurance, or otherwise compromise the
     confidentiality of communications of information regarding the issues,
     claims or actions.  The parties shall cooperate in good faith, using their
     best efforts, to address such risk management and claims handling issues in
     a manner that strongly encourages full cooperation between the parties.

     Office Manual.  Termination of a Participating Physician's participation in
     Programs shall not be deemed a termination of the Physician Agreement
     without further action on the part of IPA.

9.3  Effect of Termination.
     --------------------- 

     (a) Upon the effective termination of this Agreement, all rights and
         obligations of the parties under this Agreement shall immediately
         cease; provided, however, that IPA shall remain responsible for
         providing Covered Services under the terms of this Agreement to Members
         who are under the care of Participating Physicians at the time of such
         termination through the period for which premiums have been paid (but
         in no event more than 90 days, except that if a Member is hospitalized
         at the time of termination, until the Member is discharged), unless PHS
         makes reasonable and medically appropriate provision for the assumption
         of such services by another provider.  PHS shall compensate
         Participating Physicians for those Covered Services, for which premium
         was received, rendered prior to and following the termination date (as
         provided in this Section 9.3(a)) pursuant to the PHS/IPA fee schedule
         in effect at such time.  In the event this Agreement is terminated due
         to the last sentence of Section 9.1, the non-defaulting party shall be
         entitled to pursue all legally available remedies consistent with
         Section 10.4 herein, and damages arising out of such breach.

     (b) Upon termination, PHS is authorized to notify Members, prospective
         Members and Participating Physicians, and other persons and entities
         whom it deems to have an interest herein of such termination.
