              NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS

                                  June 30, 1996
                                   (unaudited)


1.   Basis of Presentation

     The accompanying unaudited condensed consolidated financial statements have
     been prepared in accordance with generally accepted accounting principles
     for interim financial information and with the instructions to Form 10-Q
     and Article 10 of Regulation S-X. Accordingly, they do not include all of
     the information and footnotes required by generally accepted accounting
     principles for complete financial statements. In the opinion of management,
     all adjustments (consisting solely of normal recurring accruals) considered
     necessary for a fair presentation have been included. Operating results for
     the six month period ending June 30, 1996 are not necessarily indicative of
     the results that may be expected for the year ending December 31, 1996. For
     further information, refer to the consolidated financial statements and
     footnotes thereto included in the Physicians Health Services, Inc. and
     Subsidiaries' annual report on Form 10-K for the year ended December 31,
     1995.

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


2.   Stockholders' Equity and Per Share Data

     Pursuant to the Company's Certificate of Incorporation, upon conversion of
     Class B shares to Class A shares, such Class B shares are canceled and
     cannot be reissued. Per share data are based upon the weighted average
     number of common and common equivalent shares outstanding during the
     period. Common stock equivalent shares are excluded to the extent they have
     an antidilutive effect on per share data.


3.   Long Term Debt

     In June 1996, the Company entered into a $30 million revolving credit
     agreement which expires on June 27, 2001. This agreement provides for cash
     borrowings under a line of credit at a variable spread over the London
     Interbank Offered Rate. The applicable rate at June 30, 1996 was 6.0%. At
     June 30, 1996 there was $18.0 million outstanding under this line which
     represented funds borrowed to purchase the Company's new corporate
     headquarters building. Interest payments on this debt are required to be
     paid monthly. The Company pays a commitment fee based on the unused portion
     of the line of credit. Under the terms of the agreement, the Company is
     subject to certain financial covenants, including covenants related to
     minimum net worth and operating earnings and a material adverse change 
     condition. At June 30, the Company is in compliance with all convenants.

4.   Tax Provision

     The effective tax rate for the quarter ended June 30, 1996 is a benefit of
     44.1% compared to a tax provision of 32.0% for the second quarter of 1995.
     For the six months ended June 30, 1996, the effective tax rate is a benefit
     of 46.4% as compared to a tax provision of 36.9% for 1995. The effective
     tax rate benefited from the favorable effect of income from tax exempt
     securities which increased the tax benefit available in 1996 and reduced
     the tax provisions in 1995.

                                   (unaudited)




4.   Tax Provision (cont.)

     The Company is currently under examination by the Internal Revenue Service
     (IRS) for certain prior tax years. Management does not expect any proposed
     adjustments which may result from the IRS' audit to have a material adverse
     impact on the Company's financial position or results of operations.


5.   Agreements  with  The  Guardian  Life  Insurance  Company of America

     The Company and The Guardian Life Insurance Company of America (the
     "Guardian") amended the New York reinsurance agreement to reduce the
     Company's share of the indemnity business being assumed from 50% to 10%,
     retroactive to January 1, 1996. The amendment also provides that the
     Company will assume no further indemnity business after July 1, 1996. The
     impact of this amendment reduced the Company's indemnity loss by $936
     thousand, after taxes.

     Additionally, the Company and Guardian have agreed in principle to replace,
     effective July 1, 1996, the profit sharing agreement in Connecticut with a
     reinsurance agreement similar to the arrangements in effect in New York and
     New Jersey. The reinsurance agreement would only cover the managed care
     products and would exclude indemnity business. In anticipation of
     converting from a profit sharing to a reinsurance arrangement in
     Connecticut, the Company recognized approximately $1.1 million in after tax
     losses attributable to 1995 and the first half of 1996, which otherwise
     could have been deferred to offset future income from this arrangement. If
     the Company either does not finalize the reinsurance agreement with
     Guardian or does not receive the regulatory approval required, this $1.1
     million adjustment would be reversed to income; however, it is expected
     that the agreement will be finalized and the required regulatory approval
     will be received.

premium revenues increased at a lower rate than the growth in enrollment due to
competitive conditions which depressed pricing flexibility and a shift in
product mix to lower revenue yielding and lower margin products such as the
gatekeeper products, Healthcare Solutions products and Medicaid. Also, enrollee
statistics include 100% of the enrollees in the New York Healthcare Solutions
products (which accounted for 29% of the enrollment growth from 1995) while
premium revenue includes only the Company's 50% share of revenues derived from
the NY Healthcare Solutions products. This arrangement became effective July 1,
1995. The Company expects that the growth in premium revenue may continue to lag
the growth in enrollment to the extent that the current competitive conditions
and demand for lower margin products continue.

On a year to date basis, investment income declined 1.4% from 1995 to 1996 due
to a decline in invested assets and lower investment yields due to lower
interest rates, offset in part by the interest income earned on a receivable
from Guardian.

Health care expenses as a percentage of premium revenues (medical loss ratio)
increased to 93.4% for the second quarter of 1996 as compared to 78.7% for the
comparable 1995 quarter. For the six months ended June 30, 1996, the medical
loss ratio was 89.1% compared to 79.2% for the first six months of 1995. Total
health care expenses increased $48.2 million to $108.9 million in the second
quarter of 1996 from $60.8 million for the comparable 1995 quarter. On a year to
date basis, total health care expenses increased $78.6 million to $201.8 million
for the first six months of 1996 from $123.3 million for the same 1995 period.
As a result of the competitive market conditions and demand for the Company's
lower margin products referred to above, and since a substantial portion of the
Company's premium revenue is on a calendar year renewal cycle, the Company
expects that the medical loss ratios in 1996 will continue to be higher than
those reported for the respective year earlier periods.

Hospital services expense increased 60.2% to $44.1 million for the second
quarter of 1996 from $27.5 million for the second quarter of 1995. Hospital
services expense for the first six months of 1996 totaled $83.8 million, up
56.5% from $53.5 million in the first six months of 1995. The increase in
hospital services expense is due primarily to the increase in fully-insured
membership. Inpatient hospital utilization for fully insured enrollees,
excluding Medicare cost contract enrollees, declined 16.7% to 269 days per
thousand members for the quarter ended June 30, 1996 from 323 days per thousand
members for the comparable 1995 period. For the six months ended June 30, 1996,
bed days per thousand members declined 12.9% to 275 days in 1996 from 316 days
in 1995. The decrease in inpatient hospital costs, as a result of this lower
utilization, was offset by a corresponding increase in outpatient hospital
costs. The rise in outpatient hospital costs is attributable to an increase in
the cost and complexity of outpatient procedures as more procedures are shifted
from inpatient to outpatient settings, where costs are less fixed, and due to 
increased frequency and cost of emergency room visits.

ITEM 2. MANAGEMENT'S  DISCUSSION AND ANALYSIS OF FINANCIAL CONDITION AND RESULTS
        OF OPERATIONS


Results of Operations (cont.)


Physician and related health care expenses increased by 64.0% from $30.3 million
for the second quarter of 1995 to $49.6 million for the second quarter of 1996.
For the six months ended June 30, 1996, physician and related health care
expenses increased 46.0% to $90.6 million from $62.0 million for the same 1995
period. The increase is reflective of the increase in membership offset in part
by more favorable utilization and improved fee arrangements.

Other health care expenses increased by $7.8 million in the second quarter of
1996 and by $12.8 million on a year to date basis. The increase is almost
entirely due to higher prescription drug costs resulting from a shift in
membership to drug riders that offer greater benefits, lower generic drug
utilization and unfavorable mix of medications being prescribed.

Indemnity costs reflect the medical costs associated with the indemnity business
assumed under the New York reinsurance agreement with Guardian. As a result of
continuing adverse experience related to in this business, the Company began
negotiations with Guardian to reduce the Company' participation in the
assumption of the indemnity business. As a result of the negotiations, the
Company and Guardian amended the New York reinsurance agreement to reduce the
Company's share of the indemnity business being assumed from 50% to 10%,
retroactive to January 1, 1996. The amendment also provides that the Company
will assume no further indemnity business after July 1, 1996. As a result of the
amendment, the Company will not participate in the experience of the indemnity
business written after June 30, 1996 under the Joint Marketing Arrangement with
Guardian.

The second quarter results of operations included certain items that arose out
of the Company's arrangements with Guardian. First, the impact of the amendment
to the New York reinsurance agreement referred to in the prior paragraph reduced
the Company's losses associated with the indemnity portion of this arrangement
by $1.7 million. Second, the Company recognized additional indemnity costs of
$983 thousand which related to claims in excess of the level that had previously
been estimated for 1995 and the first half of 1996. Third, the Company
recognized approximately $1.4 million of additional physician claims related to
the managed care business in Connecticut and New York above the level that had
been previously estimated for services rendered in 1995 and the first half of
1996. Fourth, there was an overaccrual of estimated premiums recorded in
Connecticut in the first quarter of 1996 which totalled $463 thousand that were
reversed during the second quarter. Fifth, in anticipation of converting from a
profit sharing to a reinsurance arrangement in Connecticut, the Company
recognized $1.9 million in losses, attributible to 1995 and the first half of
1996 as more fully described in Note 5 to the Condensed Consolidated Financial
Statements. The after tax effect of these five items in the second quarter was a
reduction in net income of approximately $1.8 million.

Selling, general and administrative expenses increased by 51.0% or $6.6 million
in the second quarter of 1996 from the comparable 1995 period. For the six
months ended June 30, 1996, selling, general and administrative expenses are up
47.0% or $12.3 million over the prior year. The increase is due primarily to the
continuing resource commitments needed to support the geographic expansion and
the enrollment growth and diversity. Selling, general and administrative
expenses as a percentage of revenue improved to 16.6% for the second quarter of
1996 as compared to 17.1% for the second quarter of 1995. On a year to date
basis, selling, general and administrative expenses as a percentage of revenue
totaled 16.7% and 16.5% for the six months ended June 30, 1996 and 1995,
respectively.

ITEM 2. MANAGEMENT'S DISCUSSION AND ANALYSIS OF FINANCIAL
        CONDITION AND RESULTS OF OPERATIONS


Results of Operations (cont.)

The Company's effective tax rate for the second quarter of 1996 is a benefit of
44.1% as compared to a tax provision of 32.0% for the second quarter of 1995.
For the six months ended June 30, 1996, the effective tax benefit rate is 46.4%
as compared to a tax provision of 36.9% for 1995. The effective tax rate
benefited from the favorable effect of income from tax exempt securities which
increased the tax benefit available in 1996 and reduced the tax provisions in
1995.


Liquidity and Capital Resources

Cash and cash equivalents increased $433 thousand at June 30, 1996 from December
31, 1995. For the six months ended June 30, 1996, $9.8 million was used by
operating activities, primarily to fund the loss for the period as well as to
fund the payment of risk retention to IPAs, physicians and other providers and
to fund the payment of accrued liabilities. During the first six months, $18.1
million was provided from a revolving credit line which was used to fund the
purchase of the Company's new corporate headquarters building in the second
quarter. Approximately $19.7 million of net cash was provided from the sales and
maturities of investments which was used to fund the enhancement of the
Company's computer systems and also to fund the risk retention payments made in
March, 1996.

Stockholders' equity declined to $104.7 million during the first six months of
1996 from $108.9 million at December 31, 1995 due primarily to the net losses.

The Company expects to spend additional capital, principally in computer and
technology system and building enhancements over the next several years. The
Company believes that in addition to its current capital resources and
internally generated funds, it will be able to draw down on the revolving credit
line or obtain financing, if necessary, sufficient for its continued operations,
the funding of geographical and product expansions, system enhancements and its
additional space requirements.

     At the Annual Meeting, the Stockholders also were asked to ratify the
appointment of Ernst & Young, LLP as independent auditors for the Company for
the fiscal year ending December 31, 1996. The total votes for, against and
withheld are as follows:

For:  14,898,413    Against:  48,081          Abstain:  25,300,565


          Due to the large number of abstentions, the motion to ratify did not
     carry. In the proxy statement for the Annual Meeting, the Board said it
     would reconsider the appointment under these circumstances. The Audit
     Committee met on July 25, 1996 and recommended that Ernst & Young continue
     to be retained. The Board approved this recommendation on July 30, 1996.

          CREDIT AGREEMENT dated as of June 27, 1996 between PHYSICIANS HEALTH
SERVICES, INC., a corporation organized under the laws of the State of Delaware
(the "Borrower"), and THE CHASE MANHATTAN BANK, N.A., a national banking
association organized under the laws of the United States of America (the
"Bank").

          The Borrower desires that the Bank extend credit as provided herein
and the Bank is prepared to extend such credit. Accordingly, the Borrower and
the Bank agree as follows:


                   ARTICLE 1. DEFINITIONS; ACCOUNTING TERMS.

          Section 1.1.  Definitions.  As used in this Agreement the following
                        -----------                                          
terms have the following meanings (terms defined in the singular to have a
correlative meaning when used in the plural and vice versa):
                                                ---- -----  

          "Acceptable Acquisition" means any Acquisition: (i) which has been
either (A) approved by the Board of Directors of the corporation which is the
subject of such Acquisition or (B) recommended by such Board to the shareholders
of such corporation; and (ii) with respect to which the following conditions are
satisfied:

               (a)  no Default or Event of Default exists or would result from
such Acquisition;

               (b)  the corporation or assets acquired involve health care and
related industries;

               (c)  the Borrower demonstrates that, on a combined basis with the
acquired assets and/or company, in accordance with GAAP, they would have been in
compliance with the financial covenants contained in Article 8 on a trailing
four quarters pro forma basis as of the end of the immediately preceding fiscal
quarter; and

               (d)  the Borrower remains as the surviving entity.

          "Acceptable Investments" means investments that are in compliance with
the Borrower's Investment Policy as set forth in Schedule 7.3 hereto or any
updated or modified Schedule 7.3 that is accepted by the Bank in its sole
discretion.

          "Acquisition" means any transaction pursuant to which the Borrower or
any of its Subsidiaries (a) acquires equity securities (or warrants, options or
other rights to acquire such securities) of any corporation other than the
Borrower or any corporation 
<PAGE>
 
which is not then a Subsidiary of the Borrower, such that such corporation would
become a Subsidiary of the Borrower, pursuant to a solicitation of tenders

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

               (a)  Subject to the terms and conditions of this Agreement, the
Bank agrees to make loans (the "Loans") to the Borrower from time to time from
and including the date hereof to and including the Termination Date, up to but
not exceeding in the aggregate principal amount at any one time outstanding, the

<PAGE>
 
outstanding as Variable Rate Loans or Eurodollar Loans (each a "type" of Loans).
Each type of Loans shall be made and maintained at the Bank's Lending Office for
such type of Loans.

               The Loans shall be due and payable on the Termination Date.

               (b)  Subject to the terms and conditions of this Agreement,
the Bank agrees, for the account of the Borrower from time to time during the
period from the date hereof until the Termination Date, to issue Letters of

exceed at any time the lesser of (i) $ Ten Million Dollars ($10,000,000) or (ii)

                        -------                                             
Loans for general corporate purchases, including for the purchase and renovation
of 1 Far Mill Road, Shelton, Connecticut, and for acquisitions.  The Borrower
shall use the Letters of Credit in connection with general corporate purposes.

stock, which shall be done in compliance with Regulation U.

                        ---------------------------                          
the right to make prepayments of principal, or to convert one type of Loans into
another type of Loans, at any time or from time to time; provided that: (a) the
Borrower shall give the Bank notice of each such prepayment or conversion as
provided in Section 2.8; and (b) if any Eurodollar Loans are prepaid or
converted other than on the last day of an Interest Period for such Loans, then

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

               (a)  In the case of each Eurodollar Loan, the Borrower shall

Interest Period in Section 1.1, subject to the following limitations:  (i) no
Interest Period may extend beyond the Termination Date; (ii) notwithstanding
clause (i) above, no Interest Period shall have a duration less than one month,
and if any such proposed Interest Period would otherwise be for a shorter
period, such Interest Period shall not be available; and (iii) no more than five
Interest Periods may be outstanding at any one time.

               (b)  Upon notice to the Bank as provided in Section 2.8, the
Borrower may renew any Eurodollar Loan on the last day of the Interest Period
therefor as the same type of Loans with an Interest Period of the same or
different duration in accordance with the limitations provided above.  If the
Borrower shall fail to give notice to the Bank of such a renewal, such
Eurodollar Loan shall automatically become a Variable Rate Loan on the last day
of the current Interest Period.

          Section 2.7.  Changes of Commitment.
                        --------------------- 

               (a)  Optional Reductions.  The Borrower shall have the right
                    -------------------                                    
to reduce or terminate the amount of unused Commitment at any time or from time
to time, provided that: (a) the Borrower shall give notice of each such
reduction or termination to the Bank as provided in Section 2.8; and (b) each
partial reduction shall be in an aggregate amount that is an integral multiple
of $1,000,000 and at least equal to $5,000,000.  The Commitment once reduced or
terminated may not be reinstated without the written agreement of the Bank in
its sole discretion.

               (b)  Additional Collateral Following Termination.  At any time 
                    -------------------------------------------      
that the Commitment is terminated pursuant to Section 9.2 or otherwise, the
Borrower shall furnish the Bank for deposit in a cash collateral account
maintained at the Bank adequate cash reserves for the benefit of the Bank on the
Termination Date in the amount of any Letters of Credit then outstanding which
have a tenor which extends beyond the Termination Date, or must otherwise
provide for a financial institution acceptable to the 

                                      -14-
<PAGE>
 
Bank to (x) issue a letter of credit in form and substance satisfactory to the
Bank naming the Bank as "beneficiary" therein, or, at the option of the Bank,
(y) otherwise indemnify the Bank against loss in connection with outstanding
Letters of Credit, pursuant to indemnification documentation in form and
substance satisfactory to the Bank.

          Section 2.8.  Certain Notices.  Notices by the Borrower to the Bank of
                        ---------------                                         
each borrowing pursuant to Section 2.4, and each prepayment or conversion
pursuant to Section 2.5 and each renewal pursuant to Section 2.6(b), and each
reduction or termination of the Commitment pursuant to Section 2.7 shall be
irrevocable and shall be effective only if received by the Bank not later than
11:00 a.m. New York City time, and (a) in the case of borrowings and prepayments
of, conversions into and (in the case of Eurodollar Loans) renewals of (i)
Variable Rate Loans, given on the Banking Day therefor; (ii) Eurodollar Loans,
given three Banking Days prior thereto; (b) in the case of reductions or
termination of the Commitment, given three Banking Days prior thereto.  Each
such notice shall specify the Loans to be borrowed, prepaid, converted or
renewed and the amount (subject to Section 2.9) and type of the Loans to be
borrowed, or converted, or prepaid or renewed (and, in the case of a Eurodollar
Loan, the Interest Period therefor) and the date of the borrowing or prepayment,
or conversion or renewal (which shall be a Banking Day).  Each such notice of
reduction or termination shall specify the amount of the Commitment to be
reduced or terminated.

          Section 2.9.  Minimum Amounts.  Except for borrowings in respect of
                        ---------------                                      
Variable Rate Loans which exhaust the full remaining amount of the Commitment,
and for prepayments or conversions which result in the prepayment or conversion
of all Loans of a particular type or conversions made pursuant to Section
3.1(b), each borrowing, prepayment, conversion and renewal of principal of Loans
of a particular type shall be in an amount at least equal to (a) $1,000,000 for
Variable Rate Loans, and (b) $3,000,000 and integral multiples of $1,000,000 in
excess thereof for Eurodollar Loans (borrowings, prepayments, conversions or
renewals of or into Loans of different types or, in the case of Eurodollar
Loans, having different Interest Periods at the same time hereunder to be deemed
separate borrowings, prepayments, conversions and renewals for the purposes of
the foregoing, one for each type of Interest Period).

          Section 2.10.  Interest.
                         -------- 

               (a)  Interest shall accrue on the outstanding and unpaid
principal amount of each Loan for the period from and including the date of such
Loan to but excluding the date such Loan is due at the following rates per
annum: (i) for a Variable Rate Loan, at a variable rate per annum equal to the
Variable Rate plus the Applicable Margin and (ii) for a Eurodollar Loan, at a
fixed rate equal to the Eurodollar Rate plus the Applicable Margin. If the
principal amount of any Loan and any other amount payable by the Borrower
hereunder or under the Note shall not be paid when due (at stated maturity, 

                                      -15-
<PAGE>
 
by acceleration or otherwise), interest shall accrue on such amount to the
fullest extent permitted by law from and including such due date to but
excluding the date such amount is paid in full at the Default Rate. After the
occurrence of an Event of Default other than payment defaults described in the
preceding sentence, then the Bank may, by written notice to the Borrower,
increase the interest rate hereunder during the continuance of such Event of
Default to the Default Rate, effective on the date of such notice.

               (b)  The interest rate on each Variable Rate Loan shall change
when the Variable Rate changes and interest on each such Loan shall be
calculated on the basis of a year of 365 (or, in the case of a leap year, 366)
days for the actual number of days elapsed. Interest on each Eurodollar Loan
shall be calculated on the basis of a year of 360 days for the actual number of
days elapsed. Promptly after the determination of any interest rate provided for
herein or any change therein, the Bank shall notify the Borrower.

               (c)  Accrued interest shall be due and payable in arrears upon
any payment of principal or conversion and (i) for each Variable Rate Loan, on
the last day of each March, June, September and December, commencing the first
such date after such Loan; (ii) for each Eurodollar Loan, on the last day of the
Interest Period with respect thereto and, in the case of an Interest Period
greater than three months, at three-month intervals after the first day of such
Interest Period; provided that interest accruing at the Default Rate shall be
due and payable from time to time on demand of the Bank.

          Section 2.11.  Fees.
                         ---- 

               (a)  Commitment Fee.  The Borrower shall pay to the Bank a
                    --------------                                       
commitment fee (the "Commitment Fee") for the period from and including the date
hereof to the Termination Date, payable in arrears upon any reduction or
termination of the Commitment and on the last day of each March, June, September
and December, commencing on the first such date after the Closing Date, on the
daily average unused Commitment of the Bank for the period for which payment is
made, at a rate per annum equal to the Applicable Percentage, calculated on the
basis of a year of 365 (or, in a leap year, 366) days for the actual number of
days elapsed.

               (b)  Letters of Credit.  For each Letter of Credit, the Borrower
                    -----------------                                 
shall: (i) pay to the Bank its standard charges for issuing said letter of
credit and for any draws under said letter of credit and (ii) an amount equal to
x] a percentage per annum equal to the Applicable Margin in effect from time to
time for Eurodollar Loans (based upon a year of three hundred sixty (360) days
elapsed), multiplied by (y) the maximum aggregate amount available to be drawn,
to be paid quarterly in arrears. The Borrower will further pay to the Bank, on
demand, all other charges, costs and expenses paid or incurred by the Bank in
connection with any Letter of Credit, and interest where chargeable, including
fees and 

                                      -16-

charges of counsel and costs allocated by the Bank's internal legal department
in connection with the preparation, performance or enforcement of any Letter of
Credit.


          Section 2.12.  Payments Generally.  All payments under this Agreement
                         ------------------                                    
or the Note shall be made in Dollars in immediately available funds not later
than 1:00 p.m. New York City time on the relevant dates specified above (each
such payment made after such time on such due date to be deemed to have been
made on the next succeeding Banking Day) to an  account designated by the Bank
and  maintained at the Lending Office of the Bank.  The Bank may (but shall not
be obligated to) debit the amount of any such payment which is not made by such
time to any ordinary deposit account of the Borrower with the Bank.  The
Borrower shall, at the time of making each payment under this Agreement or the
Note, specify to the Bank the principal or other amount payable by the Borrower
under this Agreement or the Note to which such payment is to be applied (and in
the event that it fails to so specify, or if a Default or Event of Default has
occurred and is continuing, the Bank may apply such payment as it may elect in
its sole discretion ).  If the due date of any payment under this Agreement or
the Note would otherwise fall on a day which is not a Banking Day, such date
shall be extended to the next succeeding Banking Day and interest shall be
payable for any principal so extended for the period of such extension.


                ARTICLE 3.  YIELD PROTECTION; ILLEGALITY; ETC.

          Section 3.1.  Additional Costs.
                        ---------------- 

               (a)  The Borrower shall pay to the Bank from time to time on
demand such amounts as the Bank may determine to be necessary to compensate it
for any costs which the Bank determines are attributable to its making or
maintaining any Eurodollar Loans under this Agreement or the Note or its
obligation to make any such Loans hereunder, or any reduction in any amount
receivable by the Bank hereunder in respect of any such Loans or such obligation
(such increases in costs and reductions in amounts receivable being herein
called "Additional Costs"), resulting from any Regulatory Change which:  (i)
changes the basis of taxation of any amounts payable to the Bank under this
Agreement or the Note in respect of any of such Loans (other than taxes imposed
on the overall net income of the Bank or of its Lending Office for any of such
Loans by the jurisdiction in which the principal office or such Lending Office
is located); or (ii) imposes or modifies any reserve, special deposit, deposit
insurance or assessment, minimum capital, capital ratio or similar requirements
relating to any extensions of credit or other assets of, or any deposits with or
other liabilities of, the Bank (including any of such Loans or any deposits
referred to in the definition of "Eurodollar Base Rate" in Section 1.1); or
(iii) imposes any other condition affecting this Agreement or the Note (or any
of such 

                                      -17-
<PAGE>
 
extensions of credit or liabilities). The Bank will notify the Borrower of any
event occurring after the date of this Agreement which will entitle the Bank to
compensation pursuant to this Section 3.1(a) as promptly as practicable after it
obtains knowledge thereof and determines to request such compensation.

               (b)  Without limiting the effect of the foregoing provisions of
this Section 3.1, in the event that, by reason of any Regulatory Change, the
Bank either (i) incurs Additional Costs based on or measured by the excess above
a specified level of the amount of a category of deposits or other liabilities
of the Bank which includes deposits by reference to which the interest rate on
Eurodollar Loans is determined as provided in this Agreement or a category of
extensions of credit or other assets of the Bank which includes Eurodollar Loans
or (ii) becomes subject to restrictions on the amount of such a category of
liabilities or assets which it may hold, then, if the Bank so elects by notice
to the Borrower, the obligation of the Bank to make or renew, and to convert
Loans of any other type into, Loans of such type hereunder shall be suspended
until the date such Regulatory Change ceases to be in effect and on the last
day(s) of the then current Interest Period(s) for the outstanding Loans of such
type, the Borrower shall either prepay such Loans or such Loans shall convert
into Variable Rate Loans.

               (c)  Without limiting the effect of the foregoing provisions
of this Section 3.1 (but without duplication), the Borrower shall pay directly
to the Bank from time to time on request such amounts as the Bank may determine
to be necessary to compensate the Bank for any costs which it determines are
attributable to the maintenance by it or any of its affiliates pursuant to any
law or regulation of any jurisdiction or any interpretation, directive or
request (whether or not having the force of law and whether in effect on the
date of this Agreement or thereafter) of any Governmental Authority or monetary
authority of capital in respect of its Loans hereunder or its obligation to make
Loans hereunder (such compensation to include, without limitation, an amount
equal to any reduction in return on assets or equity of the Bank to a level
below that which it could have achieved but for such law, regulation,
interpretation, directive or request).  The Bank will notify the Borrower if it
is entitled to compensation pursuant to this Section 3.1(c) as promptly as
practicable after it determines to request such compensation.

               (d)  Determinations and allocations by the Bank for purposes
of this Section 3.1 of the effect of any Regulatory Change pursuant to
subsections (a) or (b), or of the effect of capital maintained pursuant to
subsection (c), on its costs of making or maintaining Loans or its obligation to
make Loans, or on amounts receivable by, or the rate of return to, it in respect
of Loans or such obligation, and of the additional amounts required to
compensate the Bank under this Section 3.1, shall be conclusive, provided that
such determinations and allocations are made on a reasonable basis and
consistent with the Bank's policy towards loans of like type and having
substantially similar provisions as contained in this Section 3.1.

          Section 3.2.  Limitation on Types of Loans.  Anything herein to the
                        ----------------------------                         
contrary notwithstanding, if:

               (a)  the Bank determines (which determination shall be
conclusive) that quotations of interest rates for the relevant deposits referred
to in the definition of "Eurodollar Base Rate" in Section 1.1 are not being
provided in the relevant amounts or for the relevant maturities for purposes of
determining the rate of interest for any type of Eurodollar Loans as provided in
this Agreement; or

               (b)  the Bank determines (which determination shall be
conclusive) that the relevant rates of interest referred to in the definition of
"Eurodollar Base Rate" in Section 1.1 upon the basis of which the rate of
interest for Eurodollar Loans is to be determined do not adequately cover the
cost to the Bank of making or maintaining such Loans;

then the Bank shall give the Borrower prompt notice thereof, and so long as such
condition remains in effect, the Bank shall be under no obligation to make or
renew Loans of such type or to convert Loans of any other type into Loans of
such type and the Borrower shall, on the last day(s) of the then current
Interest Period(s) for the outstanding Loans of the affected type, prepay such
Loans or such Loans shall convert into Variable Rate Loans.

          Section 3.3.  Illegality.  Notwithstanding any other provision in this
                        ----------                                              
Agreement, in the event that it becomes unlawful for the Bank or its Lending
Office to (a) honor its obligation to make or renew Eurodollar Loans hereunder
or convert Loans of any type into Loans of such type, or (b) maintain Eurodollar
Loans hereunder, then the Bank shall promptly notify the Borrower thereof and
the Bank's obligation to make or renew Eurodollar Loans and to convert other
types of Loans into Loans of such type hereunder shall be suspended until such
time as the Bank may again make, renew, or convert and maintain such affected
Loans and the Borrower shall, on the last day(s) of the current Interest
Period(s) for the outstanding Eurodollar Loans (or on such earlier date as the
Bank may specify to the Borrower), either prepay such Loans or convert such
Loans into Variable Rate Loans.

          Section 3.4  Certain Compensation.  The Borrower shall pay to the Bank
                       --------------------                                     
, upon the request of the Bank, such amount or amounts as shall be sufficient
(in the reasonable opinion of the Bank) to compensate it for any loss, cost or
expense which the Bank determines is attributable to:

               (a)  any payment, prepayment, conversion or renewal of a
Eurodollar Loan made by the Bank on a date other than the last day of an
Interest Period for such Loan (whether by reason of acceleration or otherwise);
or

                                      -19-
<PAGE>
 
               (b)  any failure by the Borrower to borrow, convert into or renew
a Eurodollar Loan to be made, converted into or renewed by the Bank on the date
specified therefor in the relevant notice under Section 2.4, 2.5 or 2.6, as the
case may be.

          Without limiting the foregoing, such compensation shall include an

or endorsement, not liability. Schedule 5.19 sets forth a complete and correct
list and brief description of all insurance currently maintained by or on
respect of the Borrower, setting forth the identity of the insurance carrier,

such insurance policies except as set forth in Schedule 5.19. Schedule 5.19
identifies each insurance policy providing for a retrospective premium
adjustment or other change in compensation payable to the insurer on the basis
of claim or loss experience, and describes any liability the Borrower has in
respect of such matters.

operates as a commercial health maintenance organization is duly licensed as
such in each jurisdiction in which such license is necessary and there exists no
proceeding or other action challenging any such license.  The Borrower and each
of its Subsidiaries possess all other licenses as are necessary to conduct their
respective businesses substantially as now conducted and as presently proposed
to be conducted and there exists no proceeding or other action challenging any
such licenses.

sound banking practices, any non-public information supplied to it by the
Borrower pursuant to this Agreement which is identified by the Borrower as being
confidential at the time the same is delivered to the Bank, provided that
nothing herein shall limit the disclosure of any such information (i) to the
extent required by statute, rule, regulation or judicial process, (ii) to
counsel for the Bank , (iii) to bank examiners, auditors or accountants, (iv) in
connection with any litigation to which the Bank is a party or (v) to any
assignee or participant (or prospective assignee or participant) so long as such
assignee or participant (or prospective assignee or participant) first executes
and delivers to the Bank a Confidentiality Agreement in substantially the form
of Exhibit F hereto; and provided finally that in no event shall the Bank be
obligated or required to return any materials furnished by the Borrower.

          Section 10.15.Treatment of Certain Information.  The Borrower (a)
                        --------------------------------                   
acknowledges that services may be offered or provided to it (in connection with
this Agreement or otherwise) by the Bank or by one or more of its subsidiaries
or affiliates and (b) acknowledges that information delivered to the Bank by the
Borrower may be provided to each such subsidiary and affiliate.

          Section 10.16.Changes in Accounting Principles.
                        -------------------------------- 

               (a)  If any changes in accounting principles from those used in
the preparation of the financial statements referred to in Section 5.5 are
hereafter occasioned by the promulgation of rules, regulations, pronouncements,
or opinions of, or required by, the Financial Accounting Standards Review Board
of the American Institute of Certified Public Accountants (or successors thereto
or agencies with similar functions), or there shall occur any change in the
Borrower's or any Subsidiary's fiscal or tax years and, as a result of any such
changes, there shall result a change in the method of calculating any of the
financial covenants, negative covenants, standards, or other terms or conditions
found in this Agreement or any other Facility Document, or

                                      -46-
<PAGE>
 
               (b)  If the Borrower, for reasonable business purposes, shall
desire to change such accounting principles or the application thereof (which
change shall be consistent with accounting principles then in effect pursuant to
rules, regulations, pronouncements, or opinions or the Financial Accounting
Standards Review Board of the American Institute of Certified Public
Accountants) and such desired change would result in a change in the method of
calculating any of the financial covenants, negative covenants or other terms
and conditions found in this Agreement or any other Facility Document,

then the parties hereto agree to enter into negotiations in order to amend such
provisions and the definition of GAAP set forth in Section 1.1 so as to reflect
equitably such changes with the desired result that the criteria for evaluating
the financial condition and performance of the Borrower and its Subsidiaries
shall be the same after such changes as if such changes had not been made.

          Section 10.17.Independence of Covenants.  All covenants hereunder
                        -------------------------                          
shall be given independent effect so that if a particular action or condition is
not permitted by any of such covenants, the fact that it would be permitted by
an exception to, or be otherwise within the limitations of, another covenant
shall not avoid the occurrence of a Default or Event of Default if such action
is taken or condition exists.

          Section 10.18.Time of the Essence.  Time and punctuality shall be of
                        -------------------                                   
the essence with respect to this instrument, but no delay or failure of the Bank
to enforce any of the provisions herein contained and no conduct or statement of
the Bank shall waive or affect any of the Bank's rights hereunder.

          SECTION 10.19.COMMERCIAL WAIVER.  THE BORROWER ACKNOWLEDGES THAT THE
                        -----------------                                     
LOANS EVIDENCED BY THE NOTE ARE FOR COMMERCIAL PURPOSES AND WAIVES ANY RIGHT TO
NOTICE AND HEARING UNDER SECTIONS 52-278a THROUGH 52-278n OF THE CONNECTICUT
GENERAL STATUTES AS NOW OR HEREAFTER AMENDED AND AUTHORIZES THE ATTORNEY OF THE
BANK, OR ANY SUCCESSOR THERETO, TO ISSUE A WRIT OF PREJUDGMENT REMEDY WITHOUT
COURT ORDER.  FURTHER, THE BORROWER HEREBY WAIVES, TO THE EXTENT PERMITTED BY
LAW, THE BENEFITS OF ALL VALUATION, APPRAISEMENTS, HOMESTEAD, EXEMPTION, STAY,
REDEMPTION AND MORATORIUM LAWS NOW IN FORCE OR WHICH MAY HEREAFTER BECOME LAWS.
THE BORROWER ACKNOWLEDGES THAT IT MAKES THESE WAIVERS AND THE WAIVERS CONTAINED
IN SECTION 10.8 KNOWINGLY AND VOLUNTARILY AND ONLY AFTER EXTENSIVE CONSIDERATION
OF THE RAMIFICATIONS OF THESE WAIVERS WITH ITS ATTORNEYS.

Re:  Credit Agreement dated as of June [___], 1996 (the "Credit Agreement")

any one of the following persons to give to you instructions, including notices
required pursuant to the Agreement, orally or by telephone or teleprocess:

          NAME (Typewritten)

          _________________________

          Instructions may be honored on the oral, telephonic or teleprocess
instructions of anyone purporting to be any one of the above designated persons
even if the instructions are for the benefit of the person delivering them.  We
will furnish you with confirmation of each such instruction either by telex
(whether tested or untested) or in writing signed by any person designated above
(including any facsimile which appears to bear the signature of any person
designated above) on the same day that the instruction is provided to you but
your responsibility with respect to any instruction shall not be affected by
your failure to receive such confirmation or by its contents.

          You shall be fully protected in, and shall incur no liability to us
for, acting upon any instructions which you in good faith believe to have been
given by any person designated above, and in no event shall you be liable for

we have agreed to in writing.

          We will promptly notify you in writing of any change in the persons
designated above and, until you have actually received such written notice and
have had a reasonable opportunity to act upon it, you are authorized to act upon

                    (Letterhead of counsel to the Borrower)

                                 [Closing Date]



The Chase Manhattan Bank, N.A.
One Chase Manhattan Plaza
New York, New York  10081

Ladies and Gentlemen:

          We have acted as counsel to Physicians Health Services, Inc. (the
"Borrower") in connection with the execution and delivery of that certain Credit
Agreement (the "Credit Agreement") dated as of June [___], 1996, between the
Borrower and The Chase Manhattan Bank, N.A. (the "Bank"), and the other Facility
Documents executed in connection therewith.  Except as otherwise defined herein,
all terms used herein and defined in the Credit Agreement or any agreement
delivered thereunder shall have the meanings assigned to them therein.

          In connection with this opinion, we have examined executed copies of
the Facility Documents and such other documents, records, agreements and
certificates as we have deemed appropriate.  We have also reviewed such matters
of law as we have considered relevant for the purpose of this opinion.

          In stating our opinion, we have assumed the legal capacity of all
natural persons, the genuineness of all signatures of parties other than the
Borrower on original or certified copies, the authority of all persons signing
any document on behalf of parties thereto other than the Borrower, the
authenticity of documents submitted to us as originals and the conformity to
authentic originals of all copies submitted to us as certified or conformed
copies or photocopies.

          We have also assumed, for the purposes of the opinions expressed
herein, that the parties to the Credit Agreement and the other Facility
Documents, other than the Borrower, have the corporate power and authority to
enter into and perform each of those documents and that each of those documents
has been duly authorized, executed and delivered by each such other party.
<PAGE>
 
          Based upon the foregoing, and subject to the limitations set forth
herein, we are of the opinion that:

               1.  The Borrower and each of its Subsidiaries is a corporation
duly incorporated, validly existing and in good standing under the laws of the
jurisdiction of its incorporation, has the power and authority to own its assets
and to transact the business in which it is now engaged or proposed to be
engaged, and is duly qualified as a foreign corporation and in good standing
under the laws of each other jurisdiction in which such qualification is
required.

               2.  The execution, delivery and performance by the Borrower of
the Credit Agreement and the other Facility Documents is within the power of the
Borrower, have been duly authorized by all necessary action, and do not: (a)
require any consent or approval of the stockholders of the Borrower; (b)
contravene the charter or by-laws of the Borrower; (c) violate any provision of,
or require any filing, registration, consent or approval under, any law, rule,
regulation (including, without limitation, Regulation U), order, writ, judgment,
injunction, decree, determination or award presently in effect having
applicability to the Borrower; (d) result in a breach of or constitute a default
or require any consent under any indenture or loan or credit agreement or any
other agreement, lease or instrument to which the Borrower is a party or by
which the properties of the Borrower may be bound or affected; (e) result in, or
require, the creation or imposition of any Lien (other than in favor of the
Administrative Agent on behalf of the Banks), upon or with respect to any of the
properties now owned or hereafter acquired by the Borrower; (f) cause the
Borrower to be in default under or contravene any such law, rule, regulation,
order, writ, judgment, injunction, decree, determination or award or any such
indenture, agreement, lease, instrument or other agreements or instruments to
which the Borrower is a party or by which its properties may be bound or
affected.

               3.  The Credit Agreement and each other Facility Document to
which the Borrower is a party is a legal, valid and binding obligation of the
Borrower, enforceable against the Borrower in accordance with its terms, except
to the extent that such enforcement may be limited by applicable bankruptcy,
insolvency and other similar laws affecting creditors' rights generally.  The
Credit Agreement and each other Facility Document has been duly executed and
delivered by the Borrower.

               4.  To the best of our knowledge (after due inquiry), there are
no pending or threatened actions, suits or proceedings against or affecting the
Borrower or any of its Subsidiaries before any court, governmental agency or
arbitrator, which, in any one case or in the aggregate, could reasonably be
expected to have a Material Adverse Effect.

               5.  Neither the execution of the Credit Agreement, the making of
any loans thereunder, nor the use made or proposed to be made of the proceeds of
any 

                                      -2-
<PAGE>
 
loan thereunder constitutes or will constitute a violation of Regulation G,
Regulation T, Regulation U or Regulation X promulgated by the Board of Governors
of the Federal Reserve System.

               6.  The Borrower is not entitled to claim for itself or any of
its assets immunity from suit, execution, attachment or other legal process;
provided, however, that this opinion is subject to (a) applicable bankruptcy,
- --------  -------                                                            
insolvency, fraudulent conveyance, reorganization, moratorium, or other similar
laws now or hereafter in effect relating to creditors' rights and remedies
generally and (b) the effect of consideration of overriding principles of public
policy.

               7.  The provisions of the Credit Agreement (without regard to the
provisions thereof limiting the payment of interest or any sums thereunder to
the highest rate permitted by applicable law) do not violate any applicable law
of the State of New York relating to usury.

               8.  To the best of our knowledge (after due inquiry), the
Borrower is not in violation of any laws, ordinances, decrees, orders,
governmental rules or regulations to which it is subject, nor has it failed to
obtain any licenses, permits, franchises or other governmental authorizations
necessary to the ownership of its properties or assets or to the conduct of its
business, which violation or failure to obtain could reasonably be expected to
have a Material Adverse Effect.

               9.  Neither the Borrower nor any of its Subsidiaries is:  (a) an
"investment company" within the meaning of the Investment Company Act of 1940,
as amended;  (b) a "holding company" or an "affiliate" of a "holding company,"
or a "subsidiary company" of a "holding company," or a "public utility" within
the meaning of the Public Utility Holding Company Act of 1935, as amended; or
(c) subject to regulation under the Interstate Commerce Act, as amended, or the
Federal Power Act, as amended.

          We are members of the Bar of the State of New York and we express no
opinion as to the laws of any jurisdiction other than those of the United States
of America, the State of New York and the General Corporation Law of the State
of Delaware (the "Jurisdictions").  To the extent that any opinion set forth
herein relates to or is impacted by the law of any jurisdiction other than the
Jurisdictions, we have (with your permission) assumed that the laws of such
other jurisdiction are identical in all material respects to the laws of the
State of New York.  By expressing an opinion upon matters  governed by laws
other than the laws of the State of New York, we do not thereby assume any
greater standard of liability hereunder than would be applicable if such opinion
was based exclusively on New York laws.

                                      -3-

          This opinion letter has been required of us in connection with your
entering into the Credit Agreement with the Borrower.  We acknowledge that this
opinion is requested directly by the Bank, that the Borrower has caused this
opinion to be rendered directly to the Bank and that the Bank is relying on the
conclusions rendered in this opinion.  This opinion is intended for the
exclusive benefit of the Bank, and the benefit of its counsel, and no other
person shall be entitled to rely hereon.

party shall be allowed thirty (30) days from receipt of written notice of such

If a reasonably satisfactory plan to cure the default or breach is not submitted

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

of the Reinsurer shall have terminated pursuant to Section 8.3 of this Agreement
(the "Terminal Accounting Date").

     (b)  The Company shall supply the Reinsurer with final Schedules C and D
which shall show the Terminal Accounting and Settlement. If the Terminal
Accounting and Settlement shows a final net Loss attributable to the Company,
the Company shall pay the amount of such Loss to the Reinsurer. If the Terminal

to the Company, the Reinsurer shall pay the amount of the Profit to the Company.

the Company by reason of such supplemental accounting, plus any interest due
pursuant to Section 7.7, shall be paid promptly upon the completion of such

balance developed with respect to the Health Insurance Contracts. The Quarterly
cash balance shall consist of the prior closing cash balance, plus Direct Paid
Premium, minus Direct Paid Claims and further reduced by cash payment to the

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

     11.1 Condition Precedent.  When, under insurance, public health or other
          -------------------
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 Effective Date, the parties may mutually agree to modify the Effective
Date of this Agreement.

obligation of the Company to cede reinsurance under this Agreement, on or before

agreement by PHS to guarantee the

                                       24
<PAGE>
 
solvency of the Reinsurer. Such agreement shall be in form and content
acceptable to the Company in its sole discretion, and shall be effective for as
long as the Company seeks performance by the Reinsurer under this Agreement. Any
termination or substantial amendment of PHS' agreement to guarantee the
obligations of the Reinsurer shall be cause for termination by the Company under
Section 8.8 above.

                                  ARTICLE XII

                           INSOLVENCY OF THE COMPANY
                           -------------------------

     12.1 Payments by the Reinsurer.  In the event of the insolvency 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
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 

                                       25
<PAGE>
 
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.

     12.3 Executory Contract.  It is expressly understood that this Agreement is
          ------------------ 
an executory contract as long as both parties are required to perform under this
Agreement. On the insolvency of either party, if this Agreement is not confirmed
by the insolvent party and given status as an "Administrative Expense," then the
other party may terminate for non-performance without additional payment other
than payments relating to Health Insurance Contracts for which liability
continues under this Agreement.

          --------------------------
differences arising hereafter between the contracting parties with respect to
any transaction, matter or issue arising from or relating in any way to this
Agreement on which agreement between the parties hereto cannot be reached, the
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
two parties to this Agreement or their Affiliates. Each of the contracting
companies agrees to appoint one of the arbitrators with the third, the "Umpire,"
to be chosen by the other arbitrators. In the event 

                                       26
<PAGE>
 
that either 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 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 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 New Jersey and the laws of the State of New Jersey
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.

                       INVESTMENT INCOME INTEREST RATES
                       --------------------------------

The annual Investment Income Interest Rate shall equal the non-loaned portfolio
           ------------------------------- 
rate for the Company's general account assets for the current calendar year.
The portfolio rate shall be determined from the Annual Statement submitted to
the New York Insurance Department for the Company's general account based on the
formula given below:

                         rate = (I+CG)/(.5x(A+B-I-CG))

Where:

  A =  cash and invested assets plus accrued investment income less borrowed
       money at the end of year (page 2, line 10A less line 5 plus line 16 plus
       line 2102, less page 3, line 11.4 less line 16 less line 22 less line
       2501);

  B =  same quantity as "A" above except for the beginning of year;

  I =  net investment income for the year (exhibit 2, line 16) plus amortization
       of interest maintenance reserve (page 4, line 4A);

  CG = capital gains/loss, less interest maintenance reserve (exhibit 3, line
       10, column 4 minus footnote exhibit 3, line 2, column A plus exhibit 4,
       line 10, column 4).

The pages and lines referred to above are as they appear in the Company's 1994
Annual Statement.  These pages and lines may change from year to year.

For quarterly reporting purposes, the Investment Income Interest Rate shall be
determined based on the following, with an adjustment to reflect the actual
experience during the first quarter of the succeeding calendar year:

First quarter:    The prior year Investment Income Interest Rate.
Subsequent quarters:  A reasonable estimate of the current year Investment
Income Interest Rate.

Reinsurer reasonably relating to the HMO or POS Contracts and the administrative
responsibilities hereunder, during normal business hours for such period as this

failure to pay amounts due or to perform any other act required by this

Company, PHS (Bermuda) 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) days of notification

the Reinsurer shall share, based upon the percentages set forth in Section 2.1

results from any change in the terms or conditions of any HMO or POS Contract
reinsured hereunder or in the calculation of Reserves.  The Company must provide

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

regulations, as from time to time are in effect, so that the agreement remains

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.

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 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.

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

     12.1  Payments by the Reinsurer or PHS (Bermuda).  In the event of the
           ------------------------------------------                      
insolvency 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 or PHS (Bermuda), as the
case may be, directly to the Company or to its liquidator, receiver, or
statutory successor on the basis of the liability of the Company, the Reinsurer
and/or PHS (Bermuda) under the HMO Contracts and the POS 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

and PHS (Bermuda) shall be given written notice of the pendency of a claim
against the insolvent Company on a HMO or POS Contract reinsured hereunder
within a reasonable time after such claim is filed in the insolvency proceeding.
During the pendency of such claim, the Reinsurer or PHS (Bermuda) 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 or PHS (Bermuda) 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 or PHS (Bermuda).  Where two or more assuming 

                                       32

is an executory contract as long as both parties are required to perform under
this Agreement.  On the insolvency of any party, if this Agreement is not
confirmed by the insolvent party and given status as an "Administrative
Expense," then the other parties may terminate for non-performance without
additional payment other than payments relating to HMO or POS Contracts for
which liability continues under this Agreement.

or difference.  The arbitrators must be disinterested officers or retired

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

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 the
two remaining nominees by the President of the American Arbitration Association.

     13.2  Decision of Arbitrators; Expenses.  The arbitrators shall consider
           ---------------------------------

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

this Article XIII 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 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.

           -------------------------------                           
portfolio rate for the Reinsurer's general account assets for the current
calendar year.  The portfolio rate shall be determined from the Annual
Statement submitted to the New York Insurance Department for the Reinsurer's
general account based on the formula given below:
 
                         rate = (I+CG)/(.5x(A+B-I-CG))
 
Where:
 
     A = cash and invested assets plus accrued investment income less borrowed
money at the end of year (page 2, line 10A less line 5 plus line 16 plus line
2102, less page 3, line 11.4 less line 16 less line 22 less line 2501);
 
     B = same quantity as "A" above except for the beginning of year;
 
     I =   net investment income for the year (exhibit 2, line 16) plus
amortization of interest maintenance reserve (page 4, line 4A);
 
     CG =  capital gains/loss, less interest maintenance reserve (exhibit 3,
line 10, column 4 minus footnote exhibit 3, line 2, column A plus exhibit 4,
line 10, column 4).
 
The pages and lines referred to above are as they appear in the Reinsurer's
1994 annual statement.  These pages and lines may change from year to year.
 
For quarterly reporting purposes, the Investment Income Interest Rate shall
be determined based on the following, with an adjustment to reflect the
actual experience during the first quarter of the succeeding calendar year:
 
First quarter:  The prior year Investment Income Interest Rate.
Subsequent quarters:  A reasonable estimate of the current year Investment
Income Interest Rate.

                       AMENDMENT TO REINSURANCE AGREEMENT

     This Amendment to the Agreement (as defined below) is between The Guardian
Life Insurance Company of America ("Guardian") and Physicians Health Services
(Bermuda) Ltd ("PHS (Bermuda)") and is dated as of July 31, 1996.

     WHEREAS, Guardian and PHS (Bermuda) entered into a Reinsurance Agreement
dated April 27, 1995 (the "Agreement"), pursuant to which Guardian agreed to
cede to PHS (Bermuda) fifty percent (50%) of the risks under certain of
Guardian's health insurance contracts, as more fully described in the Agreement;
and

     WHEREAS, Guardian and PHS (Bermuda) wish to retroactively amend the
Agreement as set forth herein.

     NOW, THEREFORE, the parties hereto agree as follows:

     1. EFFECTIVE AS OF JANUARY 1, 1996 THROUGH AND INCLUDING JUNE 30, 1996:

     The Agreement is hereby amended by the deletion, in its entirety, of the
first paragraph in Schedule A to the Agreement, which states:

                                   Quota Share

                         The Reinsurer agrees to reinsure a 50% quota share (the
                    "Quota Share") of the risks on the Health Insurance
                    Contracts (as defined), issued (or to be issued) by the
                    Company in the Service Area.

; and by the substitution therefor of the following paragraph:

                                   Quota Share

                         The Reinsurer agrees to reinsure: (i) a 10% quota share
                    (the "Quota Share") of the risks on those Health Insurance
                    Contracts that are not the "out-of network" component of a
                    PHS health maintenance organization plan; and (ii) a 50%
                    Quota Share of the risks on those Health Insurance Contracts
                    that are the "out-of-network" component of a PHS health
                    maintenance organization plan.
<PAGE>
 
     2. EFFECTIVE AS OF JULY 1, 1996:

     A. The Agreement is hereby amended by the deletion, in its entirety, of the
definition of the term "Health Insurance Contracts" on page 3 of the Agreement,
which states:

               "Health Insurance Contracts" means only those health insurance
          contracts issued by the Company in the Service Area that are marketed
          (i) by the sales force of an Affiliate of the Reinsurer or the
          Company's sales force as part of a "dual choice" offering under which
          an Affiliate of the Reinsurer and the Company cooperate in offering
          managed care and health insurance arrangements, or (ii) by the sales
          force of an Affiliate of the Reinsurer in "stand alone" arrangements.
          The term Health Insurance Contract includes "preferred provider
          organization" contracts using PHS' network of health care providers,
          or PHCS' network of providers when sold in conjunction with a PHS HMO
          product, and any "out-of-network" component of a health maintenance
          organization plan when such component is underwritten by the Company.

; and by the substitution therefor of the following paragraph:

               "Health Insurance Contracts" means the "out-of-network" component
          of a PHS health maintenance organization plan when such
          "out-of-network" component is underwritten by the Company and offered
          for sale in the Service Area.

     B. The Agreement is hereby amended by the deletion, in its entirety, of the
first paragraph in Schedule A to the Agreement, as amended, which states:

                                   Quota Share

               The Reinsurer agrees to reinsure: (i) a 10% quota share (the
          "Quota Share") of the risks on those Health Insurance Contracts that
          are not the "out-of network" component of a PHS health maintenance
          organization plan; and (ii) a 50% Quota Share of the risks on those
          Health Insurance Contracts that are the "out-of-network" component of
          a PHS health maintenance organization plan.

; and by the substitution therefor of the following paragraph:

                                       2
<PAGE>
 
                                   Quota Share

               The Reinsurer agrees to reinsure a 50% quota share (the "Quota
          Share") of the risks on the Health Insurance Contracts (as such
          defined term has been amended), issued (or to be issued) by the
          Company in the Service Area.

     C. The Agreement is hereby amended by the deletion, in its entirety, of
Schedule B to the Agreement, which states:

                                   SCHEDULE B
