HEALTHSOURCE, INC. AND SUBSIDIARIES

NOTES TO CONDENSED CONSOLIDATED FINANCIAL STATEMENTS (UNAUDITED)

1.  BASIS OF PRESENTATION

    The unaudited condensed consolidated financial statements have been prepared
    in accordance with generally accepted accounting principles for interim
    financial information and with the instructions to Rule 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 normal recurring adjustments
    considered necessary for a fair presentation have been included.

    The results of operations for the three month period ended March 31, 1995
    are not necessarily indicative of the results of operations to be expected
    for the full year.

2.  SUMMARY OF SIGNIFICANT INCOME STATEMENT POLICIES

    Revenue - Medical premium revenue is recognized in the month in which
    members are entitled to receive health care services. Medical premiums
    collected in advance are recorded as deferred revenue. Administrative and
    managed care fees are recognized in the period that claims processing and
    other managed care services are provided to self-funded clients. Revenue
    from management service agreements is recognized in the period the Company
    performs the services.

    Cost of Medical Premiums - Cost of medical premiums includes the costs of
    all medical services delivered to enrolled members of the Company's
    majority-owned entities and for whom the entities have recorded medical
    premium revenue during the reporting period. These costs include payments
    for specific medical services and for capitation. The cost of specific
    medical services include those paid to physicians, hospitals, and other
    health care providers on a fee-for-service basis. These costs include claims
    paid, claims in process and pending, and estimates of unreported claims and
    charges at the balance sheet date for which the Company will be responsible.
    Adjustments to prior period estimates are reflected in the current period
    and are not significant. The costs of capitation (fixed monthly payments per
    member) include payments to certain physicians, hospitals, laboratories,
    pharmaceutical and mental health care providers.

    Selling, General and Administrative (SG&A) Expense - SG&A expense includes
    the costs recognized by the Company and its majority-owned entities: (1) to
    market and administer the delivery of medical services for which the Company
    is at risk; (2) to market and administer the delivery of medical services
    for self-insured clients; and (3) to develop and administer its management
    services agreements. The Company does not separately present direct costs
    associated with its administrative and management fee revenues as these
    costs are not specifically identifiable.

3.  ACQUISITIONS

    1994 Acquisitions - In January 1994, the Company acquired the remaining
    60.2% interest in Healthsource Maine, Inc. (HSME). Under the terms of the
    agreement, the Company made a cash payment of $11.5 million in exchange for
    all of the shares of HSME which it did not already own.

    On March 31, 1994, the Company acquired the remaining 69.9% of Healthsource
    Health Plans, Inc. (HSHP), the parent company of Healthsource North
    Carolina, Inc. (HSNC). Under the terms of the agreement, HSHP shareholders
    received approximately 1.24 million shares of the Company's common stock. In
    addition, certain existing options held by HSHP management were converted to
    options to purchase approximately 153,000 shares of Healthsource stock with
    an exercise price of approximately $4.60 per share.


                                        6

    In November 1994, the Company completed a cash tender offer and subsequent
    merger to purchase the remaining 60% interest in CNY which resulted in a
    total purchase price of approximately $11 million. The transaction was
    accounted for as a purchase.

    The following unaudited pro forma consolidated statement of operations
    assumes the HSHP and CNY acquisitions occurred on January 1, of each year
    (in thousands, except per share data):

4.  INCOME TAXES

    The Company provides for income taxes based upon an estimate of its annual
    effective tax rate. The estimated effective tax rates for the three months
    ended March 31, 1995 and 1994 were 33.7% and 27.0%, respectively.

5.  COMMITMENTS AND CONTINGENCIES

    In October 1994, the Company announced that a definitive merger agreement
    was approved pursuant to which the Company would acquire Health New England,
    Inc. (HNE), an HMO serving western Massachusetts. Under the merger
    agreement, all outstanding HNE shares will be exchanged for approximately
    $59,260,000 in the Company's stock in a pooling of interests transaction.
    The transaction is subject to reaching new long-term hospital provider
    agreements between HNE and its major hospital providers. No preliminary
    understanding on such agreements has been reached and under the terms of the
    merger agreement, both the Company and HNE currently are entitled to
    terminate the agreement. Nevertheless, the parties continue to work toward a
    closing. In addition, the transaction is conditioned on the receipt of
    required regulatory approvals, approval of the shareholders of HNE and
    certain other conditions.

    In December 1994, the Company agreed to acquire the group health, HMO and
    third party administration business of Provident Life and Accident Insurance
    Company of America, Inc. (Provident) for a purchase price of $310 million of
    which $210 million would be paid in cash and $100 million by delivery of a
    newly issued 6.25% Series A Cumulative Convertible Preferred Stock. The
    Company intends to borrow a large portion of the money required to close the
    Provident transaction under a five-year revolving credit facility arranged
    with a bank syndicate (initially set at $175 million in availability
    increasing to $300 million in availability after the Provident closing).

    In April 1995, the Company entered into a definitive agreement to purchase
    the assets of Central Massachusetts Health Care, Inc. (CMHC) for a cash
    purchase price of approximately $62.5 million subject to certain major
    closing adjustments including but not limited to approval by the
    Massachusetts Attorney General's office and other regulatory approvals.

                        INDEPENDENT ACCOUNTANTS' REPORT

To the Board of Directors
and Shareholders of
Healthsource, Inc.
Hooksett, New Hampshire

We have reviewed the accompanying condensed consolidated balance sheet of
Healthsource, Inc. and subsidiaries as of March 31, 1995 and the related
condensed consolidated statements of operations and cash flows for the three
month periods ended March 31, 1995 and 1994. These financial statements are the
responsibility of the Company's management.

We conducted our review in accordance with standards established by the American
Institute of Certified Public Accountants. A review of interim financial
information consists principally of applying analytical procedures to financial
data and of making inquiries of persons responsible for financial and accounting
matters. It is substantially less in scope than an audit conducted in accordance
with generally accepted auditing standards, the objective of which is the
expression of an opinion regarding the financial statements taken as a whole.
Accordingly, we do not express such an opinion.

Based on our review, we are not aware of any material modifications that should
be made to such condensed consolidated financial statements for them to be in
conformity with generally accepted accounting principles.

We have previously audited, in accordance with generally accepted auditing
standards, the consolidated balance sheet of Healthsource, Inc. and subsidiaries
as of December 31, 1994 and the related consolidated statements of operations,
shareholders' equity, and cash flows for the year then ended (not presented
herein); and in our report dated February 17, 1995, we expressed an unqualified
opinion on those consolidated financial statements. In our opinion, the
information set forth in the accompanying condensed consolidated balance sheet
as of December 31, 1994 is fairly stated, in all material respects, in relation
to the consolidated balance sheet from which it has been derived.

                               HEALTHSOURCE, INC.

                     MANAGEMENT'S DISCUSSION AND ANALYSIS OF
                  FINANCIAL CONDITION AND RESULTS OF OPERATIONS

.
GENERAL

The Company has experienced substantial growth in both revenues and
profitability since its formation in New Hampshire in 1985. Revenue growth has
been accomplished through increasing membership and medical premiums per member
and administrative and managed care fees from self-insured employers and
acquisitions. The Company has made acquisitions of HMO companies resulting in
wholly-owned subsidiaries in South Carolina, Tennessee, Maine, Indiana, North
Carolina, and Syracuse, New York. The Company has formed strategic alliances
with hospitals to operate HMOs in Arkansas, Georgia, Texas, and Ohio and has
received HMO licenses in Connecticut and Kentucky. It also formed a strategic
alliance with Chubb Life Insurance Co. to operate an HMO (ChubbHealth) in
metropolitan New York City.

A number of Federal and State proposals have been made to reform the health care
system. The Clinton Administration's comprehensive reform proposal was not
enacted in 1994, but the demand for reform at the state level remains.
Healthsource anticipates that Federal and State legislatures will continue to
assess alternative health care systems and payment methodologies. Healthsource
is unable to predict which, if any, of these health care reform proposals
ultimately will be adopted. While Healthsource does not believe it would be
materially adversely impacted by most of the proposed reforms, certain proposals
could have such an impact and the imposition of a single-payor system in any
state could potentially eliminate Healthsource's business in that state.

The Company has experienced a decline in average premium yield during the first
quarter of 1995 of 1% as compared to the same period in 1994. The Company
expects this premium pricing environment to continue during 1995 and possibly
beyond. As a result of this premium pricing environment, the Company's medical
loss ratio and ultimately its profitability will depend on its ability to
control health care costs. Also, since the Company commits to provide its
services to members at agreed upon prices for one year, unexpected cost
increases during this period cannot be passed on to client-employers or to
members. The Company believes its continued profitability in the first quarter
of 1995 can be attributed primarily to increases in membership, increased
revenue from administrative and managed care services, its successful cost
control efforts, and the effect of the acquisitions of the remaining interests
in Coordinated Medical Services of North Carolina, Inc. (now called
"Healthsource Health Plans, Inc.") parent company of Healthsource North
Carolina, Inc. (HSNC) in March 1994, and Patients' Choice, Inc. (PCI) in
November 1994.

Three Months Ended March 31, 1995 Compared to Three Months Ended
March 31, 1994

Revenue increased 91% to $208 million from $109 million. The majority of the
increase was due to a 96% increase in medical premium revenue which was
attributable to: (1) $57 million in medical premium revenue due to the
acquisition of the remaining interests in the parent companies of HSNC and PCI,
(2) the net combined effect of a 38% increase in average membership and a 1%
decrease in average medical premium yield to $134 per member per month (pmpm)
from $136 pmpm at its wholly-owned subsidiaries Healthsource New Hampshire
(HSNH), Healthsource Indiana (HSIN), Healthsource Tennessee (HSTN), Healthsource
Maine (HSME), Healthsource South Carolina (HSSC), and Healthsource Arkansas
(HSAR) ("existing plans"); and (3) $2 million in medical premiums from the
commencement of operations of Healthsource Savannah (HSSV). The remaining
revenue increase was due to a 56% increase in administrative and managed care
fees to $16.2 million from $10.4 million resulting primarily from continued
growth of the Company's self-funded Point-of- Service (POS) business in New
Hampshire and Maine, workers' compensation health care administration fees in
New Hampshire, and the

                                       10

acquisition of the remaining interest in Healthsource North Carolina
Administrators (HSNCA). The Company expects the premium pricing environment to
continue to be resistant to increases during the balance of 1995 and possibly
beyond.

Cost of medical premiums (health care costs) increased 97% to $149 million from
$76 million. This increase was due to the acquisition of the remaining interests
in HSNC and PCI, the commencement of operations of HSSV, and the combined effect
of the 38% increase in average membership with a 2% increase in average cost of
medical premiums to $105 pmpm from $103 pmpm at existing plans. This 2% increase
was primarily attributable to higher levels of outpatient diagnostic testing and
physician services offset by lower inpatient costs.

The Company's medical loss ratio increased to 77.6% from 77.0% because of the
combined effect of the slight decrease in the average premium yield and the
increase in the average cost of medical premiums at existing plans, partially
offset by the acquisition of the remaining interests in HSNC and PCI which had
slightly lower medical loss ratios in 1995 than the Company's 1994 medical loss
ratio. The Company's medical loss ratio may increase if the Company is unable to
keep the cost of medical premiums in line with level or declining premium yield.

SG&A expenses increased 77.0% to $41 million from $23 million. The increase in
these expenses was primarily due to the acquisition of the remaining interest in
HSNC and PCI; higher levels of membership at existing plans; the increases in
the Company's administrative services businesses, such as its self-funded POS
and managed workers' compensation businesses; the commencement of operations at
HSSV; development expenses at start-up HMOs; and other new business development.
As a percent of revenue, SG&A expenses decreased to 19.6% from 21.1% in 1994.

Depreciation and amortization expense increased 62.1% to $3.3 million from $2.1
million primarily due to the amortization expense associated with the Company's
acquisitions of the remaining interests in HSNC and PCI.

Interest and other income increased 38.0% to $3.6 million from $2.6 million.
This increase resulted primarily from the increase in cash and marketable
securities acquired relating to the acquisition of the remaining interest in
HSNC and continued increases in cash available from operations.

The Company had no equity in the income of unconsolidated affiliates for the
period ended March 31, 1995 as compared to $1.0 million in the period ended
March 31, 1994. This decrease occurred because of the Company's acquisition of
the remaining interests in HSNC and PCI which were previously accounted for
using the equity method.

Liquidity and Capital Resources

At March 31, 1995, cash, cash equivalents and marketable securities totaled
approximately $275 million, of which $191 million were held by regulated
operating companies and was largely restricted to use in those companies. The
balance was held by the Company and resulted primarily from the proceeds of a
public stock offering completed in August 1993, dividends from subsidiaries and
from the Company's operations. During the first quarter of 1995, the Company
generated $26 million from operations and invested approximately $7.9 million in
property and equipment.

In April 1995, the Company entered into a definitive agreement to purchase the
assets of Central Massachusetts Health Care, Inc. (CMHC) for a cash purchase
price of approximately $62.5 million subject to certain closing adjustments. The
Company expects to fund this purchase price from cash and marketable securities
on hand and from the proceeds of the revolving credit facility described below.

In December 1994, the Company agreed to acquire the group health, HMO and third
party administration business of Provident Life and Accident Insurance Company
of America, Inc. (Provident) for a purchase price of $310 million of which $210


                                       11
<PAGE>   12

million is to be paid in cash and $100 million by delivery of a newly issued
6.25% Series A Cumulative Convertible Preferred Stock. The Company intends to
borrow a large portion of the money required to close the Provident transaction
under a five-year revolving credit facility arranged with a bank syndicate
(initially set at $175 million in availability increasing to $300 million in
availability after the Provident closing). The Company believes the facility
will also provide sufficient funds for current and long-term operations and
other cash acquisitions likely to be consummated in the short term.

Effects of Inflation

Historically, medical premiums and the cost of medical premiums generally have
risen at a rate higher than that for consumer goods as a whole. Nationally, the 
rate of inflation of the cost of medical premiums moderated during 1994. There
is no assurance that this trend will continue in 1995 and beyond.  There
is also no assurance that market conditions will allow the Company to increase
medical premium rates to keep pace with increases in its cost of medical
premiums given the competitive pressures on premium pricing.

The Company attempts to mitigate increases in costs of medical premiums through
some or all of the following activities: (1) improving its contracting
methodologies with providers to achieve lower costs and to promote risk-sharing;
(2) reviewing and, as necessary, modifying benefit designs so as to discourage
inappropriate levels of consumer-driven utilization; (3) using various
utilization review techniques and technologies to mitigate inappropriate use of
health care resources by providers; and (4) communicating with the Company's
primary care physicians about the impact of clinically inappropriate utilization
of health care resources.

extent specified by the Swingline Bank, a direct interest in) such Swingline
Loan in the amount of the Base Rate Loan it would have been obligated to make
pursuant to such notice of borrowing.  Anything in SECTION 2.02(a) or SECTION
4.05 to the contrary notwithstanding, each Bank shall, not later than 4:00 p.m.
New York time on the Business Day on which such notice is given (if such notice 
is given by 2:15 p.m. New York time) or 9:00 a.m. New York time on the next
succeeding Business Day (if such notice is given after 2:15 p.m. New York time),

be) to the Administrative Agent at the account specified in SECTION 2.02(a) and
the amount so received by the Administrative Agent shall be made available to
the Swingline Bank by depositing the same, in immediately available funds, in an
account of the Swingline Bank maintained with Chase at the Principal Office
designated by the Swingline Bank.  Promptly following its receipt of any payment
in respect of a Swingline Loan, the Swingline Bank shall pay to each Bank that
has acquired a participation in such Loan such Bank's proportionate share of
such payment.

        Anything in this Agreement to the contrary notwithstanding (including in
SECTION 6.02), the obligation of each Bank to make its Base Rate Loan (or
purchase its participation or direct interest in the Swingline Loan, as the case
may be) pursuant to this SECTION 2.02(b) is unconditional under any and all
circumstances whatsoever and shall not be subject to set-off, counterclaim or
defense to payment that such Bank may have or have had against the Company, the
Administrative Agent, the Swingline Bank or any other Bank and, without limiting
any of the foregoing, shall be unconditional irrespective of (i) the occurrence
of any Default, (ii) the financial condition of the Company, any Subsidiary or
Affiliate of the Company, the Administrative Agent, the Swingline Bank or any

(iii) the termination or cancellation of the Commitments; PROVIDED that no Bank
shall be obligated to make such Base Rate Loan (or to purchase its      
participation or direct interest in the Swingline Loan) if, at the time of the
making of such Swingline Loan, the Swingline Bank had actual knowledge (as
determined pursuant to SECTION 10.03) that a Default had occurred and was
continuing.  The Company agrees that any Bank so purchasing a participation (or
direct interest) in such Swingline Loan may exercise all rights of set-off,
bankers' lien, counterclaim or similar rights with respect to such participation
as fully as if such Bank were a direct holder of a Swingline Loan in the amount
of such participation.

        If any Bank shall default in its obligation to make its Base Rate Loan
to refinance any Swingline Loan (or purchase its participation or direct
interest in such Swingline Loan, as the case may be) pursuant to the first
paragraph of this SECTION 2.02(b), then for so long as such default shall
continue, the Administrative Agent shall at the request of the Swingline Bank,
withhold from any payments received by the Administrative Agent under this
Agreement or any Note for account of such Bank the amount so in default and the
Administrative Agent shall pay the same to the Swingline Bank up to the amount
and in satisfaction of such defaulted obligation, which amount the Swingline
Bank will apply to the repayment of the principal of such Swingline Loan (if
such Bank defaulted in its obligation to make its Base Rate Loan) or otherwise
to the purchase of the participation or direct interest to be purchased by such
Bank.

for which offers were requested;

        (C)  in the case of a LIBOR Auction, the margin above or below the

those set forth in the applicable Money Market Quote Request and, in particular,
no Money Market Quote may be conditioned upon acceptance by the Company of
all (or some specified minimum) of the principal amount of the Money Market Loan
for which such Money Market Quote is being made.

        (d)  The Administrative Agent shall (x) in the case of a Set Rate
Auction, as promptly as practicable after the Money Market Quote is submitted
(but in any event not later than 10:15 a.m. New York time on the Quotation Date)
or (y) in the case of a LIBOR Auction, by 4:00 p.m. New York time on the day a
Money Market Quote is submitted, notify the Company of the terms (i) of any
Money Market Quote submitted by a Bank that is in accordance with SECTION
2.03(c) and (ii) of any Money Market Quote that amends, modifies or is otherwise
inconsistent with a previous Money Market Quote submitted by such Bank with
respect to the same Money Market Quote Request.  Any such subsequent Money
Market Quote shall be disregarded by the Administrative Agent unless such
subsequent Money Market Quote is submitted solely to correct a manifest error in
such former Money Market Quote.  The Administrative Agent's notice to the
Company shall specify (A) the aggregate principal amount of the Money Market
Borrowing for which offers have been received and (B) the respective principal
amounts and LIBO Margins or Set Rates, as the case may be, so offered by each
Bank (identifying the Bank that made each Money Market Quote).

Day prior to the proposed date of borrowing, in the case of a LIBOR Auction or
(y) the Quotation Date, in the case of a Set Rate Auction (or, in any such case,
such other time and date as the Company and the Administrative Agent, with the
consent of the Majority Banks, may agree), the Company shall notify the
Administrative Agent of its acceptance or nonacceptance of the offers so
communicated to it pursuant to SECTION 2.03(d) (and the failure of the Company
to give such notice by such time shall constitute nonacceptance) and the
Administrative Agent shall promptly notify each affected Bank.  In the case of
acceptance, such notice shall specify the

aggregate principal amount of offers for each Interest Period that are
accepted.  The Company may accept any Money Market Quote in whole or in part
(PROVIDED that any Money Market Quote accepted in part shall be at least
$5,000,000 or a larger multiple of $1,000,000; PROVIDED that:

        (i)  the aggregate principal amount of each Money Market Borrowing may
not exceed the applicable amount set forth in the related Money Market Quote
Request;

        (ii)  the aggregate principal amount of each Money Market Borrowing
shall be at least $5,000,000 (or a larger multiple of $1,000,000) but shall not
cause the limits specified in SECTION 2.03(a) to be violated;

        (iii)  acceptance of offers may be made only in ascending order of LIBO
Margins or Set Rates, as the case may be, in each case beginning with the lowest
rate so offered; and

        (iv)  the Company may not accept any offer where the Administrative
Agent has advised the Company that such offer fails to comply with SECTION
2.03(c)(ii) or otherwise fails to comply with the requirements of this Agreement
(including SECTION 2.03(a)).

If offers are made by two or more Banks with the same LIBO Margins or Set Rates,
as the case may be, for a greater aggregate principal amount than the amount in
respect of which offers are accepted for the related Interest Period, the
principal amount of Money Market Loans in respect of which such offers are
accepted shall be allocated by the Company among such Banks as nearly as
possible (in amounts of at least $2,500,000 or any larger multiple of
$500,000) in proportion to the aggregate principal amount of such offers. 
Determinations by the Company of the amounts of Money Market Loans shall be
conclusive in the absence of manifest error.

        (f)  Any Bank whose offer to make any Money Market Loan has been
accepted shall, not later than 1:00 p.m. New York time on the date specified for
the making of such Loan, make the

the terms and conditions of this Agreement, be made available to the Company on
such date by depositing the same, in immediately available funds, in an account
of the Company maintained with Chase at the Principal Office designated by the
Company.

        (g)  Except for the purpose and to the extent expressly stated in
SECTIONS 2.06(c) and 2.07 and without limiting the effect of SECTION
2.03(a)(ii), the amount of any Money Market Loan made by any Bank shall not
constitute a utilization of such Bank's Commitment.

Agreement, the Commitments may be utilized, upon the request of the Company, in
addition to the Loans provided for by SECTION 2.01(a), by the issuance by the
Issuing Bank of letters of credit (collectively, "LETTERS OF CREDIT") for the
account of the Company or any of its Subsidiaries (as specified by the Company);
PROVIDED that in no event shall (i) the aggregate amount of all Letter of Credit
Liabilities, together with the aggregate principal amount of the Loans exceed
the aggregate amount of the Commitments as in effect from time to time, (ii) the
outstanding aggregate amount of all Letter of Credit Liabilities exceed
$5,000,000 and (iii) the expiration date of any Letter of Credit extend beyond
the earlier of the Maturity Date and the date twelve months following the
issuance of such Letter of Credit.  The following additional provisions shall
apply to Letters of Credit:

        (a)  The Company shall give the Administrative Agent at least three
Business Days' irrevocable prior notice (effective upon receipt) specifying the
Business Day (which shall be no later than 30 days preceding the Maturity Date)
each Letter of Credit is to be issued and describing in reasonable detail the
proposed terms of such Letter of Credit (including its beneficiary) and the
nature of the transactions or obligations

proposed to be supported (including whether such Letter of Credit is to be a
commercial letter of credit or a standby letter of credit).  The Company
shall be the account party for each Letter of Credit, including Letters of
Credit issuable to a beneficiary having a claim or potential claim against a
Subsidiary of the Company.  Upon receipt of any such notice, the Administrative
Agent shall advise the Issuing Bank of the contents.

        (b)  On each day during the period commencing with the issuance by the
Issuing Bank of any Letter of Credit and until such Letter of Credit shall have
expired or been terminated or, if drawn upon, until the resulting Reimbursement
Obligations have been reimbursed in full by the Company (whether by a borrowing
under this agreement or otherwise), the Commitment of each Bank shall be deemed
to be utilized for all purposes of this Agreement in an amount equal to such
Bank's Commitment Percentage of the then Letter of Credit Liabilities associated
with such Letter of Credit.  Each Bank (other than the Issuing Bank) agrees
that, upon the issuance of any Letter of Credit it shall automatically acquire a
participation in the Issuing Bank's liability under such Letter of Credit in an
amount equal to such Bank's Commitment Percentage of such liability, and each
Bank (other than the Issuing Bank) thereby shall absolutely, unconditionally and
irrevocably assume, as primary obligor and not as surety, and shall be
unconditionally obligated to the Issuing Bank to pay and discharge when due, its
Commitment Percentage of the Issuing Bank's liability under such Letter of
Credit.

        (c)  Upon receipt from the beneficiary of any Letter of Credit of any
demand for payment under such Letter of Credit, the Issuing Bank shall promptly
notify the Company (through the Administrative Agent) of the amount to be paid
by the Issuing Bank as a result of such demand and the date on which payment is
to be made by the Issuing Bank to such beneficiary in respect of such demand. 
The Company hereby unconditionally agrees to pay and reimburse the
Administrative Agent for the account of the Issuing Bank for the amount of each
demand for payment under such Letter of Credit at or prior to the date on which
payment is to be made by the Issuing Bank to the beneficiary under such Letter

of Credit, without presentment, demand, protest or other formalities of any
kind.

        (d)  Forthwith upon its receipt of a notice referred to in clause (c) of
this SECTION 2.04, the Company shall advise the Administrative Agent whether or
not the Company intends to borrow under SECTION 2.01 to finance its obligation
to reimburse the Issuing Bank for the amount of the related demand for payment
and, if it does, submit a notice of such borrowing as provided in SECTION 4.05. 
In the event that the Company fails to so advise the Administrative Agent, or if
the Company fails to reimburse the Issuing Bank for a demand for payment under a
Letter of Credit by the date of such payment, the Administrative Agent shall
give each Bank prompt notice of the amount of the demand for payment, specifying
such Bank's Commitment Percentage of the amount of the related demand for
payment.

        (e)  Each Bank (other than the Issuing Bank) shall pay to the
Administrative Agent for the account of the Issuing Bank at the Principal Office
in Dollars and in immediately available funds, the amount of such Bank's
Commitment Percentage of any payment under a Letter of Credit upon notice by the
Administrative Agent to such Bank requesting such payment and specifying such
amount as provided in clause (d) of this SECTION 2.04.  Each such Bank's
obligation to make such payments to the Administrative Agent for the account of
the Issuing Bank under this clause (e), and the Issuing Bank's right to receive
the same, shall be absolute and unconditional and shall not be affected by any
circumstance whatsoever, including (i) the failure of any other Bank to make its
payment under this clause (e), the financial condition of the Company (or any
other account party), the existence of any Default or (ii) the termination of
the Commitments; PROVIDED that no Bank shall be obligated to make such payment
(or to purchase its participation or direct interest in the Letter of Credit)
if, at the time of issuing such Letter of Credit, the Issuing Bank had actual
knowledge (as determined pursuant to SECTION 10.03) that a Default had occurred
and was continuing.  Each such payment to the Issuing Bank shall be made without
any offset, abatement, withholding or reduction whatsoever.

        (f)  Upon the making of each payment by a Bank to the Issuing Bank
pursuant to clause (e) above in respect of any Letter of Credit, such Bank
shall, automatically and without any further action on the part of the
Administrative Agent, the Issuing Bank or such Bank, acquire (i) a participation
in an amount equal to such payment in the Reimbursement Obligation owing to the
Issuing Bank by the Company under this Agreement and under the Letter of Credit
Documents relating to such Letter of Credit and (ii) a participation in a
percentage equal to such Bank's Commitment Percentage in any interest or other
amounts payable by the Company under such Letter of Credit Documents and the
other Basic Documents in respect of such Reimbursement Obligation (other than
the commissions, charges, costs and expenses payable only to the Issuing Bank
pursuant to clause (g) of this SECTION 2.04).  Upon receipt by the Issuing Bank
from or for the account of the Company of any payment in respect of any
Reimbursement Obligation or any such interest or other amount (including by way
of set-off or application of proceeds of any collateral security) the Issuing
Bank shall promptly pay to the Administrative Agent for the account of each Bank
who shall have previously assumed a participation in such payment under clause
(ii) above, such Bank's Commitment Percentage of such payment, each such payment
by the Issuing Bank to be made in the same money and funds in which received by
the Issuing Bank.  In the event any payment received by the Issuing Bank and so
paid to the Banks is rescinded or must otherwise be returned by the Issuing
Bank, each Bank shall, upon the request of the Issuing Bank (through the
Administrative Agent), repay to the Issuing Bank (through the Administrative
Agent) the amount of such payment paid to such Bank, with interest at the rate
specified in clause (j) of this SECTION 2.04.

        (g)  The Company shall pay to the Administrative Agent for the account
of the Issuing Bank in respect of each Letter of Credit an issuance fee in an
amount equal to .1250% of the face amount of such Letter of Credit (such fee to
be nonrefundable and to be paid in advance on such date of issuance) plus all
commissions, charges, costs and expenses in the amounts customarily charged by
the Issuing Bank from time to time in like circumstances with respect to the
issuance of each Letter of

In addition, the Company shall pay to the Administrative Agent for the account
of each Bank a letter of credit fee in respect of each Letter of Credit on the
daily average undrawn face amount of such Letter of Credit for the period from
and including the date of issuance of   such Letter of Credit to and including
the date such Letter of Credit is drawn in full, expires or is terminated (such
fee to be non-refundable, to be paid in arrears on each Quarterly Date and on
the Maturity Date and to be calculated, for any day, after giving effect to any
payments made under such Letter of Credit on such day) in an amount equal to
.4500% per annum or, for any Quarterly Period prior to the first day of which
(and in any event no later than 45 days after the end of the fiscal quarter most
recently ended) the Company has delivered to the Administrative Agent a
certificate of the Company calculating the Leverage Ratio as at the last day of
such fiscal quarter (other than such portion of such period during which a
Default shall be continuing), the percentage per annum set forth below opposite
the Leverage Ratio for the Company reflected on such certificate:

     Leverage Ratio                     Percentage Rate

     Less than or equal to 0.25              .2000%
     From in excess of 0.25 to 0.35          .2250%
     From in excess of 0.35 to 0.40          .3250%
     Greater than 0.40                       .4500%

        (h)  Promptly following the end of each calendar month, the Issuing Bank
shall deliver (through the Administrative Agent) to each Bank and the Company a
notice describing the aggregate amount of all Letters of Credit outstanding at
the end of such month.  Upon the request of any Bank from time to time, the
Issuing Bank shall deliver any other information reasonably requested by such
Bank with respect to each Letter of Credit then outstanding.

        (i)  The issuance by the Issuing Bank of each Letter of Credit shall be

conditions precedent

support such transactions as shall be satisfactory to the Issuing Bank
consistent with its then current practices and procedures with respect to
letters of credit of the same type and (ii) the Company shall have executed and
delivered such applications, agreements and other instruments relating to such

application, agreement or other instrument and the provisions of this Agreement,
the provisions of this Agreement shall control.

        (j)  To the extent that any Bank fails to pay any amount required to be
paid pursuant to clause (e) or (f) of this SECTION 2.04 when due, such Bank
shall pay interest to the Issuing Bank (through the Administrative Agent) on
such amount from and including such due date to but excluding the date such
payment is made (i) during the period from and including such due date to but
excluding the date three Business Days thereafter, at a rate per annum equal to
the Federal Funds Rate (as in effect from time to time) and (ii) thereafter, at
a rate per annum equal to the Base Rate plus 2.0%.

        (k)  The issuance by the Issuing Bank of any modification or supplement
to any Letter of Credit shall be subject to the same conditions applicable under
this SECTION 2.04 to the issuance of new Letters of Credit, and no such
modification or supplement shall be issued unless either (x) the respective
Letter of Credit as affected by such action would have complied with such
conditions had it originally been issued in such modified or supplemented form
or (y) each Bank shall have consented to such modification or supplement.

        (l)  The obligations of the Company under this SECTION 2.04 shall be
unconditional and absolute and shall not be affected, modified or impaired, upon
the happening at any time or from time to time of any event, including any of

the extent, of any direct, as opposed to consequential, damages suffered by
the Company which the Company proves were caused by (i) the Issuing Bank's
willful misconduct or gross negligence in determining whether a document
presented under any Letter of Credit complies with the terms of such Letter of
Credit or (ii) the Issuing Bank's willful failure to pay under the Letter of
Credit after presentation to it of documents strictly complying with the terms
and conditions of such Letter of Credit.  In furtherance and not in limitation
of the foregoing, the Issuing Bank may accept documents that appear on their
face to be in order, without responsibility for further investigation,
regardless of any notice or information to the contrary.

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

        (a)  The Swingline Bank hereby agrees, on the terms and conditions of
this Agreement, to make loans ("SWINGLINE LOANS") to the Company in Dollars
during the period from and including the date of this Agreement to but not
including the Maturity Date in an aggregate principal amount at any one time
outstanding up to but not exceeding the Swingline Commitment; PROVIDED that the
aggregate unpaid principal amount of all Swingline Loans, together with the
aggregate unpaid principal amount of all Syndicated Loans and all Money Market
Loans and the aggregate amount of all Letter of Credit Liabilities at any one
time outstanding, may not exceed the aggregate amount of the Commitments. 
Subject to the terms of this Agreement, the Company may borrow, repay and
reborrow the amount of the Swingline Commitments by means of Base Rate Loans.

        (b)  The Company shall, not later than 11:00 a.m. New York time on the
date on which the Company proposes to borrow a Swingline Loan, give the
Administrative Agent (which shall promptly notify the Swingline Bank and the
Banks) notice of such borrowing (a "SWINGLINE BORROWING NOTICE"), which notice

Company maintained with Chase at the Principal Office designated by the Company.

        2.06   Changes of Commitments.
               -----------------------

        (A)  VOLUNTARY.  The Company shall have the right at any time or from
time to time (i) so long as no Loans are outstanding, to terminate the
Commitments and (ii) to reduce the aggregate unused amount of the Commitments
(for which purpose use of the Commitments shall be deemed to include the
aggregate principal amount of all Money Market Loans and Swingline Loans);
PROVIDED that (x) the Company shall give notice of each such termination or
reduction as provided in SECTION 4.05 and (y) each partial reduction shall be in
an aggregate amount at least equal to $25,000,000 or in any larger multiple of
$5,000,000.  The Commitments once terminated or reduced may not be reinstated.

        (b)    MANDATORY.  

        (i) If the Provident Acquisition shall not have been consummated and the
conditions specified in SECTION 6.02(c) shall not have been satisfied (or waived
by all of the Banks) by October 31, 1995, the aggregate Commitments shall be
automatically reduced to $175,000,000 on such date.  

        (ii)   If the Company receives credits against the Purchase Price (as
defined in the Provident Purchase Agreement) 

                               Credit Agreement

pursuant to SECTION 6.04 of the Provident Purchase Agreement, the aggregate
Commitments in excess of $175,000,000 shall be automatically reduced by
fifty percent (50%) of the amount of any such credits in excess of $30,000,000.

To the extent that, after giving effect to such reductions, the aggregate
principal amount of Loans, together with the aggregate amount of all Letter of
Credit Liabilities would exceed the Commitments, the Company shall, first,
prepay Loans and, second, provide cover for Letter of Credit Liabilities by
paying to the Administrative Agent in immediately available funds an amount
equal to the required amount, which funds shall be retained by the
Administrative Agent in the Collateral Account subject to and in accordance with
SECTION 10.09, in an aggregate amount equal to such excess.

        (c)    UPON MATURITY.  The aggregate amount of the Commitments shall be
automatically reduced to zero on the Maturity Date.

        2.07   FEES.

        (a)    FACILITY FEE.  The Company shall pay to the Administrative Agent

Commitment for the period from and including the Signing Date to but not
including the earlier of the date such Commitment is terminated and the Maturity
Date, at the rate of (a) for the first Quarterly Period, .1250% per annum and
(b) thereafter, .1750% per annum or, for any Quarterly Period prior to the first
day of which (and in any event no later than 45 days after the end of the fiscal
quarter most recently ended) the Company has delivered to the Administrative
Agent a certificate of the Company calculating the Leverage Ratio as at the last
day of such fiscal quarter (other than such portion of such period during which
a Default shall be continuing), the percentage per annum set forth below
opposite the Leverage Ratio for the Company reflected on such certificate:

and on the earlier of each of the date the relevant Commitments are terminated
and the Maturity Date.

        (b)    MONEY MARKET QUOTE REQUEST FEE.  The Company shall pay to the
Administrative Agent a solicitation fee equal to $750 for each Money Market
Quote Request made by the Company.  Accrued solicitation fees shall be payable

terminated and the Maturity Date.

        2.08   LENDING OFFICES.  The Loans of each Type made by each Bank shall
be made and maintained at such Bank's Applicable Lending Office for Loans of
such Type.

        2.09   SEVERAL OBLIGATIONS; REMEDIES INDEPENDENT.  The failure of any
Bank to make any Loan to be made by it on the date specified for such Loan shall
not relieve any other Bank of its obligation to make its Loan on such date, but
neither any Bank nor the Administrative Agent shall be responsible for the
failure of any other Bank to make a Loan to be made by such other Bank, and no
Bank shall have any obligation to the Administrative Agent or any other Bank for
the failure by such Bank to make any Loan required to be made by such Bank.  The
amounts payable by the Company at any time under this Agreement and under the
Notes to each Bank shall be a separate and independent debt and each Bank shall
be entitled to protect and enforce its rights arising out of this Agreement and
the Notes, and it shall not be necessary for any other Bank or the
Administrative Agent to consent to, or be joined as an additional party in, any
proceedings for such purposes.

dated the Closing Date, payable to such Bank in a principal amount equal to the
amount of its Commitment as originally in effect and otherwise duly completed.

        (b)    The Money Market Loans made by any Bank shall be evidenced by a
single promissory note of the Company substantially in the form of EXHIBIT A-2,
dated the Closing Date, payable to such Bank and otherwise duly completed.
        
        (c)    The Swingline Loans made by the Swingline Bank shall be evidenced

be recorded by such Bank on its books and, prior to any transfer of the Note
evidencing the Loans of such Class held by it, endorsed by such Bank on the
schedule attached to such Note or any continuation of such Note; PROVIDED that
the failure of such Bank to make any such recordation or endorsement shall not
affect the obligations of the Company to make a payment when due of any amount
owing under this Agreement or under such Note in respect of the Loans to be
evidenced by such Note.

        (e)    No Bank shall be entitled to have its Notes subdivided, by

2.11   OPTIONAL PREPAYMENTS AND CONVERSIONS OR  CONTINUATIONS OF LOANS.  Subject
to SECTION 4.04, the Company shall have the right to prepay Syndicated Loans, or
to Convert Syndicated Loans of one Type into Syndicated Loans of another Type or
Continue Syndicated Loans of one Type as Syndicated Loans of the same Type, at
any time or from time to time; PROVIDED that:  (a) the Company shall give the
Administrative Agent notice of each such prepayment, Conversion or Continuation
as provided in SECTION 4.05 (and, upon the date specified in any such notice of
prepayment, the amount to be prepaid shall become due and payable under this
Agreement); and (b) Fixed Rate Loans may be prepaid or Converted only on the
last day of an Interest Period for such Loans.  Money Market Loans may not be
prepaid.  Notwithstanding the foregoing, and without limiting the rights and
remedies of the Banks under SECTION 9, in the event that any Event of Default
shall have occurred and be continuing, the Administrative Agent may (and at the
request of the Majority Banks shall) suspend the right of the Company to Convert
any Loan into a Fixed Rate Loan, or to Continue any Loan as a Fixed Rate Loan,
in which event all Loans shall be Converted into (on the last day(s) of their
respective Interest Periods) or Continued as, as the case may be, Base Rate
Loans.

        2.12   Extension of Maturity Date.
               ---------------------------

        (a)    REQUEST FOR EXTENSION.  The Company may request the Banks to
extend the Maturity Date for a period of one year by delivering a written
request for such extension to the Administrative Agent no more than 45 days
prior to the first anniversary of the Signing Date and, if such extension has
been effected, the Company may again request that the Banks extend the Maturity
Date for one additional period of one year by delivering a written request for
such additional extension to the Administrative Agent no more than 45 days prior
to the second anniversary of the Signing Date.  Such extension or extensions
shall be conditioned upon the unanimous consent of the Banks.  Each Bank may
withhold its consent to any such extension in its sole discretion.  Any Bank
that shall not have indicated its determination under this SECTION 2.12 to the
Administrative Agent prior to the first or second anniversary of the Signing
Date, as

applicable, shall be deemed not to have consented to any such extension.

        (b)    REPLACEMENT OF NON-CONSENTING BANKS.  If a Bank or Banks (other
than the Administrative Agent or the Issuing Bank) shall have failed to consent
to an extension requested in accordance with clause (a) above (the
"NON-CONSENTING BANKS") but at least Banks holding ninety percent of the
Commitments shall have consented to such an extension, the Company may request
the Administrative Agent to use reasonable efforts to arrange an assignment,
pursuant to an Assignment and Acceptance, of all such Non-Consenting Banks'
Loans, Notes, Commitments, Letter of Credit Interest and all related rights,
remedies, powers and privileges under the Basic Documents to a replacement Bank
acceptable to the Administrative Agent, the Issuing Bank and the Company, and
each Bank hereby consents to such an assignment in the event it becomes a
Non-Consenting Bank.  Any assignment made by a Non-Consenting Bank pursuant to
this SECTION 2.12(b) shall be effective as of the applicable anniversary of the
Signing Date and be subject to the provisions of SECTION 11.06(b) and shall
satisfy the following additional conditions:  (x) the Company shall promptly pay
when due all reasonable fees and expenses of the Non-Consenting Bank incurred or
to be incurred in connection with such assignment; (y) any assignment of such
Non-Consenting Bank's Loans, Notes, Commitments, Letter of Credit Interest and
all of its related rights, remedies, powers and privileges under the Basic
Documents shall be made without recourse, representation or warranty (other than
the representation and warranty that the Non-Consenting Bank is the legal and
beneficial owner of the interest being assigned, free and clear of any adverse
claim); and (z) the assignee shall pay the Administrative Agent for the account
of the Non-Consenting Bank in immediately available funds all amounts
outstanding or payable under this Agreement or any other Basic Document to such
Non-Consenting Bank.

        (a)  SYNDICATED LOANS.  The Company hereby promises to pay to the
Administrative Agent for the account of each Bank the entire outstanding
principal amount of such Bank's Loans, and each Loan shall mature, on the
Maturity Date.  In addition, if at any time the aggregate principal amount of
the Loans, together with the aggregate amount of all Letter of Credit
Liabilities, shall exceed the Commitments, the Company shall, first, prepay
Loans and, second, provide cover for Letter of Credit Liabilities as specified
in SECTION 2.06(b), in an aggregate amount equal to such excess.

        (b)  MONEY MARKET LOANS.  The Company hereby promises to pay to the
Administrative Agent for the account of each Bank that makes any Money Market
Loan the principal amount of such Money Market Loan, and such Money Market Loan
shall mature, on the last day of the Interest Period for such Money Market Loan.

        (c)  SWINGLINE LOANS.  The Company hereby promises to pay to the
Administrative Agent for the account of the Swingline Bank the principal amount
of any Swingline Loan, and such Swingline Loan shall mature on the earlier of
(i) the borrowing date of the Syndicated Loan or Money Market Loan (whichever
first occurs) immediately succeeding the borrowing date of any such Swingline
Loan, the proceeds of which shall be used to pay such Swingline Loan, (ii) 60
days following the borrowing date of such Swingline Loan and (iii) the Maturity
Date.

        3.02   INTEREST.  The Company hereby promises to pay to the
Administrative Agent for the account of each Bank interest on the unpaid
principal amount of each Loan made by such Bank for the period from and
including the date of such Loan to but excluding the date such Loan shall be
paid in full, at the following rates per annum:

Interest Period, the Fixed Rate for such Loan for such Interest Period PLUS the
Applicable Margin;

        (c)    if such Loan is a LIBOR Market Loan, the LIBO Rate for such Loan
for its Interest Period PLUS (or MINUS) the LIBO Margin quoted by the Bank
making such Loan in accordance with SECTION 2.03; and

        (d)    if such Loan is a Set Rate Loan, the Set Rate for such Loan for
its Interest Period quoted by the Bank making such Loan in accordance with
SECTION 2.03.

Notwithstanding the foregoing, the Company hereby promises to pay to the
Administrative Agent for the account of each Bank interest at the applicable
Post-Default Rate on any Obligation held by such Bank to or for the account of
such Bank, which shall not be paid in full when due (whether at stated maturity,
by acceleration, by mandatory prepayment or otherwise), for the period from and
including the due date of any such amount to but excluding the date the same is
paid in full.  Accrued interest on each Loan shall be payable (i) in the case of
a Base Rate Loan, quarterly on the Quarterly Dates, (ii) in the case of a Fixed
Rate Loan or a Money Market Loan, on the last day of each Interest Period for
such Loan and, if such Interest Period is longer than 90 days (in the case of a
Set Rate Loan) or three months (in the case of a Eurodollar Loan or a LIBOR
Market Loan), at ninety-day or three-month intervals, respectively, following
the first day of such Interest Period, and (iii) in the case of any Loan, upon
the payment or prepayment of such Loan or the Conversion of such Loan to a Loan
of another Type (but only on the principal amount so paid, prepaid or
Converted), except that interest payable at the Post-Default Rate shall be
payable from time to time on demand.  Promptly after the determination of any   
interest rate provided for in this Agreement or any change in any such interest
rate, the Administrative Agent shall give notice of

        4.01   Payments.
               ---------

        (a)  Except to the extent otherwise provided in this Agreement, all
payments of any Obligations, except to the extent otherwise provided in any
other Basic Document, shall be made in Dollars, in immediately available funds,
without deduction, set-off or counterclaim, to the Administrative Agent at
account number NYA0-DI-900-9-000002 maintained by the Administrative Agent with
Chase at the Principal Office (or such other account as the Administrative Agent
shall have designated in writing to the Company), not later than 1:00 p.m. New
York time on the date on which such payment shall become due (each such payment
made after such time on such due date to be deemed to have been made on the next
succeeding Business Day).

        (b)  The Company shall, at the time of making each payment under this
Agreement of any Obligation for the account of any Bank, specify to the
Administrative Agent (which shall so notify each intended recipient) to which
Obligation such payment is to be applied (and in the event that the Company
fails to so specify, or if an Event of Default has occurred and is continuing,
the Administrative Agent may distribute such payment to the Banks for
application in such manner as it or the Majority Banks, subject to SECTION 4.02,
may determine to be appropriate).

        (c)  Each payment received by the Administrative Agent under this
Agreement of any Obligation for the account of any Bank shall be paid by the
Administrative Agent promptly to such Bank, in immediately available funds, for
the account of such Bank's Applicable Lending Office for the Loan or other
obligation in respect of which such payment is made.

interest shall be payable for any principal so extended for the period of such
extension.

        4.02   PRO RATA TREATMENT.  Except to the extent otherwise provided in
this Agreement:  (a) each borrowing of Loans, other than Money Market Loans or
Swingline Loans, shall be made from the Banks, each payment of facility fees
under SECTION 2.06 in respect of Commitments shall be made for the account of
the Banks, each termination or reduction of the amount of the Commitments under
SECTION 2.05 shall be applied to the respective Commitments of the Banks and
each participation in any Letter of Credit shall be allocated among the Banks,

making, Conversion and Continuation of Loans of a particular Type (other than
Conversions provided for by SECTION 5.04) shall be made pro rata among the
relevant Banks according to the amounts of their respective Commitments (in the
case of making of Loans) or their respective Loans (in the case of Conversions
and Continuations of Loans) and the applicable Interest Period for each Loan of
such Type shall be coterminous; and (c) each payment on account of any
Obligations to or for the account of one or more of the Banks in respect of any
Obligations due on a particular day (or, if such day is not a Business Day, the
next succeeding Business Day) shall be entitled to priority over payments in
respect of Obligations not then due and shall be allocated among the Banks
entitled to such payments PRO RATA in accordance with the respective amounts due
and payable to such Banks on such day (or Business Day) and shall be distributed
accordingly; PROVIDED that if immediately prior to giving effect to any such
payment in respect of any Syndicated Loans the outstanding principal amount of
the Syndicated Loans shall not be held by the Banks pro rata in accordance with
their respective  Commitments in effect at the time such Loans were made (by
reason of a failure of a Bank to make a Loan under this Agreement in the
circumstances described in the last paragraph of SECTION 11.04), then such
payment shall be applied to the Syndicated Loans in such manner as shall result,
as nearly as is practicable, in the outstanding principal amount of the
Syndicated Loans being held by the Banks pro rata in accordance with their
respective

the case of shortfall, the differential indemnity and other amounts owing to or
for the account of a particular Bank or Banks pursuant to any provisions of
any Basic Document which, by their terms, require differential payments.

        4.03   COMPUTATIONS.  Interest on Money Market Loans and Fixed Rate
Loans, facility fees and letter of credit fees shall be computed on the basis of
a year of 360 days and the actual number of days elapsed (including the first
day but excluding the last day) occurring in the period for which payable) and
interest payable at the Base Rate shall be computed on the basis of a year of
365 or 366 days, as the case may be, and the actual number of days elapsed
(including the first day but excluding the last day) occurring in the period for
which payable.  Notwithstanding the foregoing, for each day that the Base Rate
is calculated by reference to the Federal Funds Rate, interest payable at the
Base Rate shall be computed on the basis of a year of 360 days and the actual
number of days elapsed.

        4.04   MINIMUM AMOUNTS.  Except for mandatory prepayments made pursuant
to SECTION 2.06(b) and Conversions or prepayments made pursuant to SECTION 5.04,
each borrowing, Conversion and partial prepayment of principal of Loans shall be

$1,000,000 (borrowings, Conversions or prepayments of or into Loans of different
Types or, in the case of Fixed Rate Loans, having different Interest Periods at
the same time to be deemed separate borrowings, Conversions and prepayments for
purposes of the foregoing, one for each Type or Interest Period). 
Notwithstanding any other provision of this Agreement, the aggregate principal
amount of Fixed Rate Loans of each Type having the same Interest Period shall be
in an amount at least equal to $5,000,000 or any larger multiple of $1,000,000
and, if any Fixed Rate Loans would otherwise be in a lesser principal amount for
any period, such Loans shall be Base Rate Loans during such period.

Each such notice of borrowing, Conversion, Continuation or optional prepayment
shall specify the Class of Loans to be borrowed, Converted, Continued or prepaid

Converted, Continued or prepaid (and, in the case of a Conversion, the Type of
Loan to result from such Conversion) and the date of borrowing, Conversion,

outstanding as a Fixed Rate Loan) will be automatically Converted into a
Base Rate Loan on the last day of the then current Interest Period for such Loan
or (if outstanding as a Base Rate Loan) will remain as, or (if not then
outstanding) will be made as, a Base Rate Loan.

        4.06   NON-RECEIPT OF FUNDS BY THE ADMINISTRATIVE AGENT.  Unless
the Administrative Agent shall have been notified by a Bank or the Company (the
"PAYOR") prior to the date on which the Payor is to make payment to the
Administrative Agent of (in the case of a Bank) the proceeds of a Loan to be
made by such Bank, or a participation in a Letter of Credit drawing to be
acquired by such Bank, under this Agreement or (in the case of the Company) a
payment to the Administrative Agent for the account of one or more of the Banks
(the "REQUIRED PAYMENT"), which notice shall be effective upon receipt, that the
Payor does not intend to make the Required Payment to the Administrative Agent,
the Administrative Agent may assume that the Required Payment has been made and
may, in reliance upon such assumption (but shall not be required to), make the
amount of such payment available to the intended recipient on such date; and, if
the Payor has not in fact made the Required Payment to the Administrative Agent,
the recipient or recipients of such payment shall, on demand, repay to the
Administrative Agent the amount so made available together with interest on such
amount in respect of each day during the period commencing on the date (the
"ADVANCE DATE") such amount was so made available by the Administrative Agent
until the date the Administrative Agent recovers such amount at a rate per annum
equal to the Federal Funds Rate for such day and, if such recipient or
recipients shall fail promptly to make such payment, the Administrative Agent
shall be entitled to recover such amount, on demand, from the Payor, together
with interest as set forth above; PROVIDED that if neither the recipient or
recipients nor the Payor shall return the Required Payment to the Administrative
Agent within three Business Days of the Advance Date, then, retroactively to the
Advance Date, the Payor and the recipient or recipients shall each be obligated
to pay interest on the Required Payment as follows:

        (a)  if the Required Payment shall represent a payment to be made by the
Company to the Issuing Bank or the Banks, the Company and the recipient or
recipients shall each be obligated retroactively to the Advance Date to pay
interest in respect of the Required Payment at the Post-Default Rate (and, in
case the recipient or recipients shall return the Required Payment to the
Administrative Agent, without limiting the obligation of the Company under
SECTION 3.02 to pay interest to such recipient or recipients at the Post-Default
Rate in respect of the Required Payment); and

        (b)  if the Required Payment shall represent proceeds of a loan to be
made by the Banks to the Company, the Payor and the Company shall each be
obligated retroactively to the Advance Date to pay interest in respect of the
Required Payment at the rate of interest provided for such Required Payment
pursuant to SECTION 3.02 (and, in case the Company shall return the Required
Payment to the Administrative Agent, without limiting any claim the Company may
have against the Payor in respect of the Required Payment).

        4.07   Sharing of Payments, Etc.
               -------------------------

        (a)    The Company agrees that, in addition to (and without limitation
of) any right of set-off, banker's lien or counterclaim a Bank may otherwise
have, each Bank shall be entitled, at its option but only with the prior written
consent of the Majority Banks or the Administrative Agent, to offset balances
held by it for the account of the Company at any of its offices, in Dollars or
in any other currency, against any Obligations of the Company to such Bank that
are not paid when due (regardless of whether such balances are then due to the
Company).  Any Bank so entitled shall promptly notify the Company and the
Administrative Agent of any offset effected by it; PROVIDED that such Bank's
failure to give such notice shall not affect the validity of such offset.

        (b)    If any Bank shall obtain from the Company payment of any
Obligation through the exercise of any right of set-off, banker's lien or
counterclaim or similar right or

                               Credit Agreement

otherwise (other than from the Administrative Agent as provided in this
Agreement), and, as a result of such payment, such Bank shall have received a
greater amount of the Obligations than the amount allocable to such Bank under
SECTION 4.02, it shall promptly purchase from such other Banks participations in
(or, if and to the extent specified by such Bank, direct interests in) such
Obligations owing to such other Banks in such amounts, and make such other
adjustments from time to time as shall be equitable, to the end that all the
Banks shall share the benefit of such excess payment (net of any expenses that
may be incurred by such Bank in obtaining or preserving such excess payment) pro
rata in accordance with the unpaid Obligations owing to each of the Banks;
PROVIDED that if at the time of such payment the outstanding principal amount of
the Syndicated Loans of any Class shall not be held by the Banks pro rata in
accordance with their respective Commitments of such Class in effect at the time
such Loans were made (by reason of a failure of a Bank to make a Loan under this
Agreement in the circumstances described in the last paragraph of SECTION
11.04), then such purchases of participations and/or direct interests shall be
made in such manner as will result, as nearly as is practicable, in the
outstanding principal amount of the Syndicated Loans being held by the Banks pro
rata according to the amounts of such Commitments.  To such end all the Banks
shall make appropriate adjustments among themselves (by the resale of
participations sold or otherwise) if such payment is rescinded or must otherwise
be restored.

        (c)    The Company agrees that any Bank so purchasing such a
participation (or direct interest) may exercise all rights of set-off, banker's
lien, counterclaim or similar rights with respect to such participation as fully
as if such Bank were a direct holder of Loans or other amounts (as the case may
be) owing to such Bank in the amount of such participation.

        (d)    Nothing contained in this SECTION 4.07 shall require any Bank to
exercise any such right or shall affect the right of any Bank to exercise, and
retain the benefits of exercising, any such right with respect to any other
indebtedness or obligation of the Company.  If, under any applicable


                               Credit Agreement

in lieu of a set-off to which this SECTION 4.07 applies, such Bank shall, to the
extent practicable, exercise its rights in respect of such secured claim in a
manner consistent with the rights of the Banks entitled under this SECTION 4.07
to share in the benefits of any recovery on such secured claim.

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

        5.01   Additional Costs.
               -----------------

        (a)    The Company shall pay directly to each Bank from time to time on
demand such amounts as such Bank may determine to be necessary to compensate
such Bank for any costs that such Bank determines are attributable to its making
or maintaining of any Fixed Rate Loans or its obligation to make any Fixed Rate
Loans, or any reduction in any amount receivable by such Bank in respect of any
of such Loans or such obligation (collectively, "ADDITIONAL COSTS"), resulting
from any Regulatory Change that:

            (i)  changes the basis of taxation of any amounts payable to such
Bank under this Agreement or its Notes in respect of any of such Loans (other
than changes in the rate of taxation imposed on or measured by the overall
net income of such Bank or of its Applicable Lending Office for any of such
Loans by the jurisdiction in which such Bank has its principal office or such
Applicable Lending Office); or

            (ii)  imposes or modifies any reserve, special deposit or similar
requirements (other than the Reserve Requirement utilized in the determination
of the Fixed Rate or LIBO Rate, as the case may be, for such Loan) relating to
any extensions of credit or other assets of, or any deposits with or other
liabilities of, such Bank (including any of such Loans or any deposits referred
to in the definition of "FIXED BASE RATE" in SECTION 1.01), or any commitment of
such Bank (including the Commitments of such Bank); or

                               Credit Agreement

            (iii)  imposes any other condition affecting this Agreement or its
Notes (or any of such extensions of credit or liabilities) or its Commitments; 

PROVIDED that any such Bank shall not have the right to collect any such costs
under this SECTION 5.01(a) unless (such Bank certifies (which certification
shall be conclusive) that it is the policy of such Bank, at the time of such
collection, to collect similar payments from similarly situated borrowers, if
any.  In addition, if any Bank requests compensation from the Company under this
SECTION 5.01(a), the Company may, by notice to such Bank (with a copy to the
Administrative Agent), suspend the obligation of such Bank thereafter to make or
to Continue Loans of the Type with respect to which such compensation is
requested, or to Convert Loans of any other Type into Loans of such Type, until
the Regulatory Change giving rise to such request ceases to be in effect (in
which case the provisions of SECTION 5.04 shall be applicable); PROVIDED that
such suspension shall not affect the right of such Bank to receive the
compensation so requested.

        (b)    Without limiting the effect of the foregoing provisions of this
SECTION 5.01, in the event that, by reason of any Regulatory Change, any Bank
either (i) incurs (or would incur) Additional Costs as a result of its exceeding
a specified level of a category of deposits or other liabilities of such Bank
that includes deposits by reference to which the interest rate on Eurodollar
Loans is determined as provided in this Agreement or of a category of extensions
of credit or other assets of such Bank that includes Eurodollar Loans or (ii)
becomes subject to restrictions on the amount of such a category of liabilities
or assets that it may hold, then, if such Bank so elects by notice to the
Company (with a copy to the Administrative Agent), the obligation of such Bank
to make or Continue, or to Convert Loans of any other Type into, Loans of such
Type shall be suspended until such Regulatory Change ceases to be in effect (in
which case the provisions of SECTION 5.04 shall be applicable).

        (c)    Without limiting the effect of the foregoing provisions of this
SECTION 5.01 (but without duplication), the Company shall pay directly to each
Bank from time to time on

                               Credit Agreement

such Bank (or, without duplication, the bank holding company of which such Bank
is a subsidiary) for any costs that it determines are attributable to the
maintenance by such Bank (or any Applicable Lending Office or such bank holding
company), pursuant to any Governmental Rule (i) following any Regulatory
Change or (ii) implementing any risk-based capital guideline or other
requirement (whether or not having the force of law and whether or not the
failure to comply would be unlawful) of capital in respect of its Commitments or
Loans (such compensation to include an amount equal to any reduction of the rate
of return on assets or equity of such Bank (or any Applicable Lending Office or
such bank holding company) to a level below that which such Bank (or any
Applicable Lending Office or such bank holding company) could have achieved but
for such Governmental Rule); provided that any such Bank shall not have the
right to collect any such costs under this SECTION 5.01(c) unless (such Bank
certifies (which certification shall be conclusive) that it is the policy of
such Bank, at the time of such collection, to collect similar payments from
similarly situated borrowers, if any.

        (d)    Each Bank shall notify the Company of any event occurring after
the date of this Agreement entitling such Bank to compensation under paragraph
(a) or (c) of this SECTION 5.01 as promptly as practicable, but in any event
within 45 days, after such Bank obtains actual knowledge of such event; PROVIDED
that (i) if any Bank fails to give such notice within 45 days after it obtains
actual knowledge of such event, such Bank shall, with respect to compensation
payable pursuant to this SECTION 5.01 in respect of any costs resulting from
such event, only be entitled to payment under this SECTION 5.01 for costs
incurred from and after the date 45 days prior to the date that such Bank does
give such notice and (ii) each Bank will designate a different Applicable
Lending Office for the Loans of such Bank affected by such event if such
designation will avoid the need for, or reduce the amount of, such compensation
by an amount determined by such Bank to be material and will not, in the sole
opinion of such Bank, be disadvantageous to such Bank, except that such Bank
shall have no obligation to designate an

will furnish to the Company a certificate setting forth the basis and amount of
each request by such Bank for compensation under paragraph (a) or (c) of this
SECTION 5.01.  Determinations and allocations by any Bank for purposes of this
SECTION 5.01 of the effect of any Regulatory Change pursuant to paragraph (a) or
(b) of this SECTION 5.01, or of the effect of capital maintained pursuant to
paragraph (c) of this SECTION 5.01, on its costs or rate of return of
maintaining Loans or its obligation to make Loans, or on amounts receivable by
it in respect of Loans, and of the amounts required to compensate such Bank
under this SECTION 5.01, shall be conclusive; PROVIDED that such determinations
and allocations are made on a reasonable basis.

        (e)  Within ten days of notice to the Company of any request for
compensation by a Bank (a "REPLACED BANK") under paragraph (a) or (c) of this
SECTION 5.01, or the occurrence of any event permitting a Bank to cease making
Fixed Rate Loans under SECTION 5.01(b) (but giving effect to SECTION 5.04) or
making a Fixed Rate Loan illegal under SECTION 5.03, the Company may request the
Administrative Agent to use reasonable efforts to arrange an assignment,
pursuant to an Assignment and Acceptance, of all of such Replaced Bank's Loans,
its Notes, its Commitments, its Letter of Credit Interest and all of its related
rights, remedies, powers and privileges under the Basic Documents to a
replacement Bank acceptable to the Administrative Agent, the Issuing Bank and
the Company, and each Bank hereby consents to such an assignment in the event it
becomes a Replaced Bank.  Any assignment made by a Replaced Bank pursuant to
this SECTION 5.01(e) shall be subject to the provisions of SECTION 11.06(b) and
shall satisfy the following additional conditions:  (x) the Company shall
promptly pay when due all reasonable fees and expenses of the Replaced Bank
incurred or to be incurred in connection with such assignment; (y) any
assignment of such Replaced Bank's Loans, its Notes, its Commitments, its Letter
of Credit Interest and all of its related rights, remedies, powers and

adverse claim); and (z) the assignee shall pay the Administrative Agent for the
account of the Replaced Bank in immediately available funds all amounts

such assigning Bank.  In the event of a termination of the Commitments of,
repayment of all Obligations owing to, and termination of the Letter of Credit
Interests of, a Replaced Bank pursuant to this SECTION 5.01(e), such Bank shall
cease to be a Bank for the purposes of the Basic Documents.

        5.02   LIMITATION ON TYPES OF LOANS.  Notwithstanding any other
provision of this Agreement, if, on or prior to the determination of any Fixed
Base Rate for any Interest Period:

        (a)    the Administrative Agent determines, which determination shall be
conclusive, that quotations of interest rates for the relevant deposits referred
to in the definition of "FIXED BASE RATE" in SECTION 1.01 are not being provided
in the relevant amounts or for the relevant maturities for purposes of
determining rates of interest for any Type of Fixed Rate Loans as provided in
this Agreement; or

        (b)    if the Majority Banks determine (or any Bank that has outstanding
a Money Market Quote with respect to a proposed LIBOR Market Loan determines),
which determination shall be conclusive, and notify (or notifies, as the case
may be) the Administrative Agent that the relevant rates of interest referred to
in the definition of "FIXED BASE RATE" in SECTION 1.01 upon the basis of which
the rate of interest for Eurodollar Loans (or LIBOR Market Loans, as the case
may be) for such Interest Period is to be determined are not likely to cover
adequately the cost to such Banks (or to such quoting Bank) of making or
maintaining such Type of Loans for such Interest Period;

then the Administrative Agent shall give the Company and each Bank prompt notice
of such determination and, so long as such condition remains in effect, the
Banks (or such quoting Bank) shall be under no obligation to make additional
Loans of such Type, to Continue Loans of such Type or to Convert Loans of any

days of the then current Interest Period or Periods for the outstanding
Loans of such Type, either prepay such Loans or Convert such Loans into another
Type of Loan in accordance with SECTION 2.11.

        5.03   ILLEGALITY.  Notwithstanding any other provision of this
Agreement, in the event that it becomes unlawful or, by reason of a Regulatory
Change, impossible for any Bank or its Applicable Lending Office to honor its
obligation to make or maintain Eurodollar Loans or LIBOR Market Loans, then such
Bank shall promptly notify the Company of such event (with a copy to the
Administrative Agent) and such Bank's obligation to make or to Continue, or to
Convert Loans of any other Type into, Eurodollar Loans shall be suspended until
such time as such Bank may again make and maintain Eurodollar Loans (in which
case the provisions of SECTION 5.04 shall be applicable), and such Bank shall no
longer be obligated to make any LIBOR Market Loan that it has offered to make.

        5.04   TREATMENT OF AFFECTED LOANS.  If the obligation of any Bank to
make a particular Type of Fixed Rate Loans or to Continue, or to Convert Loans
of any other Type into, Loans of a particular Type shall be suspended pursuant
to SECTION 5.01 or SECTION 5.03 (Loans of such Type being called "AFFECTED
LOANS" and such Type being called the "AFFECTED TYPE"), such Bank's Affected
Loans shall be automatically Converted into Base Rate Loans on the last day or
days of the then current Interest Period or Periods for Affected Loans (or, in
the case of a Conversion required by SECTION 5.01(b) or SECTION 5.03, on such
earlier date as such Bank may specify to the Company with a copy to the
Administrative Agent) and, unless and until such Bank gives notice as provided
below that the circumstances specified in SECTION 5.01 or SECTION 5.03 that gave
rise to such Conversion no longer exist:

        (a)    to the extent that such Bank's Affected Loans have been so
Converted, all payments and prepayments of principal that would otherwise be
applied to such Bank's Affected Loans shall be applied instead to its Base Rate
Loans;

<PAGE>   75


        (b)    all Loans that would otherwise be made or Continued by such Bank
as Loans of the Affected Type shall be made or Continued instead as Base Rate
Loans, and all Loans of such Bank that would otherwise be Converted into Loans
of the Affected Type shall be Converted instead into (or shall remain as) Base
Rate Loans; and

        (c)    if Loans of other Banks of the Affected Type are subsequently
Converted into Loans of another Type (other than Base Rate Loans), such Bank's
Base Rate Loans shall be auto- matically Converted on the Conversion date for
such Loans of the other Banks into Loans of such other Type to the extent
necessary so that, after giving effect to such Conversion, all Loans held by
such Bank and the Banks whose Loans are so Converted are held pro rata (as to
principal amounts, Types and Interest Periods) in accordance with their
respective Commitments.

If such Bank gives notice to the Company with a copy to the Administrative Agent
that the circumstances specified in SECTION 5.01 or SECTION 5.03 that gave rise
to the Conversion of such Bank's Affected Loans pursuant to this SECTION 5.04
no longer exist (which such Bank agrees to do promptly upon such circumstances
ceasing to exist) at a time when Loans of the Affected Type made by other Banks
are outstanding, such Bank's Base Rate Loans shall be automatically Converted,
on the first day or days of the next succeeding Interest Period or Periods for
such outstanding Loans of the Affected Type, to the extent necessary so that,
after giving effect to such Conversions, all Loans held by the Banks holding
Loans of the Affected Type and by such Bank are held pro rata (as to principal
amounts, Types and Interest Periods) in accordance with their respective
Commitments.

        5.05   COMPENSATION.  The Company shall pay to the Administrative Agent
for the account of each Bank, upon the request of such Bank through the
Administrative Agent, such amount or amounts as shall be sufficient (in the
reasonable opinion of such Bank) to compensate it for any loss, cost or expense
that such Bank determines is attributable to:

        (a)    any payment, mandatory or optional prepayment or Conversion of a
Fixed Rate Loan or a Set Rate Loan made by such Bank for any reason (including
the acceleration of the Loans pursuant to SECTION 9) on a date other than the
last day of the Interest Period for such Loan; or

        (b)    any failure by the Company for any reason (including the failure
of any of the conditions precedent specified in SECTION 6 to be satisfied) to
borrow a Fixed Rate Loan or a Set Rate Loan (with respect to which, in the case
of a Money Market Loan, the Company has accepted a Money Market Quote) from such
Bank on the date for such borrowing specified in the relevant notice of
borrowing given pursuant to SECTION 2.02 or SECTION 2.03(b).

Without limiting the effect of the preceding sentence, such compensation shall
include an amount equal to the excess, if any, of (i) the amount of interest
that otherwise would have accrued on the principal amount so paid, prepaid or
Converted or not borrowed for the period from the date of such payment, 
prepayment, Conversion or failure to borrow to the last day of the then current
Interest Period for such Loan (or, in the case of a failure to borrow, the
Interest Period for such Loan that would have commenced on the date specified
for such borrowing) at the applicable rate of interest for such Loan provided
for in this Agreement over (ii) the amount of interest that otherwise would have
accrued on such principal amount at a rate per annum equal to the interest
component of the amount such Bank would have bid in the London interbank market
(if such Loan is a Eurodollar Loan or a LIBOR Market Loan) or the United States
secondary certificate of deposit market (if such Loan is a Set Rate Loan) for
Dollar deposits of leading banks in amounts comparable to such principal amount
and with maturities comparable to such period (as reasonably determined by such
Bank).

shall be imposed, modified or deemed applicable any tax, reserve, special
deposit, capital adequacy or similar requirement against or with respect to or

issuing (or purchasing participations in) or maintaining its or their obligation
to issue (or purchase participations in) any Letter of Credit or reduce any
amount receivable by any Bank in respect of any Letter of Credit (which
increases in cost, or reductions in amount receivable, shall be the result of
such Bank's or Banks' reasonable allocation of the aggregate of such increases
or reductions resulting from such event), then, upon demand by such Bank or
Banks (through the Administrative Agent), the Company shall pay immediately to
the Administrative Agent for the account of such Bank or Banks, from time to
time as specified by such Bank or Banks (through the Administrative Agent), such
additional amounts as shall be sufficient to compensate such Bank or Banks
(through the Administrative Agent) for such increased costs or reductions in
amount.  A statement as to such increased costs or reductions in amount incurred
by any such Bank or Banks, submitted by such Bank or Banks to the Company, shall

event that it becomes unlawful or, by reason of any Regulatory Change,
impossible for any Bank to issue (or to participate in) any Letter of Credit,
then such Bank shall promptly notify the Company of such event (with a copy to
the Administrative Agent) and the Banks' obligation to issue (or participate in)
any Letter of Credit shall be suspended until such time as each Bank may again
issue (or participate in) Letters of Credit.

that date.

        7.03   LITIGATION.  Except as disclosed to the Banks in SCHEDULE IV,
there are no legal or arbitral proceedings, or any proceedings by or before any
Governmental Person now pending or (to the knowledge of the Company) threatened
against the Company or any of its Subsidiaries which, if adversely determined,
could have a Material Adverse Effect.

        7.04   NO BREACH.  None of the execution and delivery of the Basic
Documents, the consummation of the transactions contemplated in the Basic
Documents or compliance with the terms and provisions of the Basic Documents
will conflict with or result in a breach of, or require any consent under, the
charter or by-laws of the Company or any applicable Governmental Rule or any
agreement or instrument to which the Company or any of its Subsidiaries is a
party or by which any of them or any of their Property is bound or to which any

execution, delivery or performance by the Company of the Basic Documents or for
the legality, validity or enforceability of any Basic Document.

engaged principally, or as one of its important activities, in the business of
extending credit for the purpose, whether immediate, incidental or ultimate, of
buying or carrying Margin Stock, and no part of the proceeds of any extension of
credit under this Agreement will be used to buy or carry any Margin Stock.

conducted), and no claims are being asserted or contested with respect to such
taxes that are required by generally accepted accounting principles to be
reflected in its financial statements referred to in SECTION 7.02 and are not so
reflected.  The charges, accruals and reserves on the books of the Company and
its Subsidiaries in respect of taxes and other governmental charges are
considered by the Company to be adequate.

statute of limitations relating to the payment of Federal or other taxes.

in accordance with the instructions given by the Majority Banks or all of
the Banks as is required in such circumstance, and such instructions of such
Banks and any action taken or failure to act pursuant to such instructions shall
be binding on all of the Banks.

        10.03  DEFAULTS.  The Administrative Agent shall not be deemed to have
knowledge or notice of the occurrence of a Default unless the Administrative
Agent has received notice from a Bank or the Company specifying such Default and
stating that such notice is a "NOTICE OF DEFAULT."  In the event that the
Administrative Agent receives such a notice of the occurrence of a Default, the
Administrative Agent shall give prompt notice of such receipt to the Banks (and
shall give each Bank prompt notice of each such nonpayment).  The Administrative
Agent shall (subject to SECTION 10.07) take such action with respect to such
Default as shall be directed by the Majority Banks or; PROVIDED that, unless and
until the Administrative Agent shall have received such directions, the
Administrative Agent may (but shall not be obligated to) take such action, or
refrain from taking such action, with respect to such Default as it shall deem
advisable in the best interest of the Banks except to the extent that this
Agreement expressly requires that such action be taken, or not be taken, only
with the consent or upon the authorization of the Majority Banks or all of the
Banks.

        10.04  RIGHTS AS A BANK.  With respect to its Commitments and the Loans
made by it, Chase (and any successor acting as Administrative Agent) in its
capacity as a Bank under the Basic Documents shall have the same rights,
privileges and powers under the Basic Documents as any other Bank and may
exercise the same as though it were not acting as the Administrative Agent, and
the term "BANK" or "BANKS" shall, unless the context otherwise indicates,
include the Administrative Agent in its individual capacity.  Chase (and any
successor acting as Administrative Agent) and its affiliates may (without having
to account for the same to any Bank) accept deposits from, lend money to, make
investments in and generally

engage in any kind of banking, trust or other business with the Company (and any
of its Subsidiaries or Affiliates) as if it were not acting as the
Administrative Agent, and Chase and its affiliates may accept fees and other
consideration from the  Company for services in connection with this Agreement
or otherwise without having to account for the same to the Banks.

        10.05  INDEMNIFICATION.  The Banks agree to indemnify the Administrative
Agent and its affiliates, directors, officers, employees, attorneys and agents
(to the extent not reimbursed under SECTION 11.03, but without limiting the
obligations of the Company under SECTION 11.03) ratably in accordance with their
respective Commitments, for any and all losses, liabilities, damages or expenses
(a) incurred by any of them in connection with or by reason of any actual or
threatened investigation, litigation or other proceedings (including any such
investigation, litigation or other proceedings between the Administrative Agent
and any Bank) relating to the extensions of credit under, and the transactions
contemplated by, the Basic Documents or any actual or proposed use by the
Company or any of its Subsidiaries of the proceeds of any such extensions of
credit (or arising under any Environmental Law as provided in the last sentence
of SECTION 11.03), including the reasonable fees and disbursements of counsel
incurred in connection with any such investigation, litigation or other
proceedings and (b) payable or reimbursable to the Administrative Agent pursuant
to clause (a), (b) or (c) of SECTION 11.03 but not paid or reimbursed by or on
behalf of the Company when due (but excluding in any such case any such losses,
liabilities, damages or expenses to the extent, but only to the extent, incurred
by reason of the gross negligence or willful misconduct of the Person to be
indemnified).

        10.06  NONRELIANCE ON ADMINISTRATIVE AGENT AND OTHER BANKS.  Each Bank
agrees that it has, independently and without reliance on the Administrative
Agent or any other Bank, and based on such documents and information as it has
deemed appropriate, made its own credit analysis of the Company and its
Subsidiaries and decision to enter into this Agreement and that it will,
independently and without reliance upon the Administrative Agent

or any other Bank, and based on such documents and information as it shall deem
appropriate at the time, continue to make its own analysis and decisions
in taking or not taking action under this Agreement.  The Administrative Agent
shall not be required to keep itself informed as to the performance or
observance by the Company of any Basic Document or any other document referred
to or provided for in any Basic Document or to inspect the Properties or books
of the Company or any of its Subsidiaries.  Except for notices, reports and
other documents and information expressly required to be furnished to the Banks
by the Administrative Agent under this Agreement, the Administrative Agent shall
not have any duty or responsibility to provide any Bank with any credit or other
information concerning the affairs, financial condition or business of the
Company or any of its Subsidiaries (or any of their Affiliates) that may come
into the possession of the Administrative Agent or any of its affiliates.

        10.07  FAILURE TO ACT.  Except for action expressly required of the
Administrative Agent under the Basic Documents, the Administrative Agent shall
in all cases be fully justified in failing or refusing to act under any Basic
Document unless it shall receive further assurances to its satisfaction from the
Banks of their indemnification obligations under SECTION 10.05 against any and
all liability and expense that may be incurred by it by reason of taking or
continuing to take any such action.

        10.08  RESIGNATION OR REMOVAL OF ADMINISTRATIVE AGENT.  Subject to the
appointment and acceptance of a successor Administrative Agent as provided
below, the Administrative Agent may resign at any time by notice to the Banks
and the Company and the Administrative Agent may be removed at any time with or
without cause by the Majority Banks.  Upon any such resignation or removal, the
Majority Banks shall have the right to appoint a successor Administrative Agent;
PROVIDED that unless a Default shall have occurred and be continuing, such
successor shall be reasonably acceptable to the Company.  If no successor
Administrative Agent shall have been so appointed by the Majority Banks and
shall have accepted such appointment within 30 days after the retiring
Administrative Agent's giving of notice of resignation or the Majority Banks'
removal of the retiring

Administrative Agent, then the retiring Administrative Agent may, on behalf of
the Banks, appoint a successor Administrative Agent, that shall be a bank which
has an office in New York, New York.  Upon the acceptance of any appointment as
Administrative Agent by a successor Administrative Agent, such successor
Administrative Agent shall thereupon succeed to and become vested with all the
rights, remedies, powers, privileges, duties and obligations of the retiring
Administrative Agent, and the retiring Administrative Agent shall be discharged
from its duties and obligations, under the Basic Documents.  After any retiring
Administrative Agent's resignation or removal as Administrative Agent, the
provisions of this SECTION 10 shall continue in effect for its benefit in
respect of any actions taken or omitted to be taken by it while it was acting as
the Administrative Agent.

        10.09  Letter of Credit Collateral Account. 
               ------------------------------------

        (a)    In the event that the Company shall be required pursuant to
SECTION 2.06(b) or the last paragraph of SECTION 9 to provide cover for Letter
of Credit Liabilities, the Administrative Agent shall establish with Chase a
separate cash collateral account (the "COLLATERAL ACCOUNT") in the name and
under the control of the Administrative Agent into which there shall be
deposited from time to time certain amounts required or contemplated to be paid
to the Administrative Agent as provided in SECTION 2.12 and the last paragraph
of SECTION 9 or otherwise.

        (b)    As collateral security for the prompt payment in full when due
(whether at stated maturity, by acceleration or otherwise) of the Reimbursement
Obligations, the Company hereby pledges and grants to the Administrative Agent,
for the benefit of the Banks and the Administrative Agent as provided in this
Agreement, a security interest in all of its right, title and interest in and to
the Collateral Account and the balances from time to time standing to the credit
of the Collateral Account (and the investments and reinvestments of such
balance, provided for below).  The balances from time to time standing to the
credit of the Collateral Account shall not constitute payment of any
Reimbursement Obligations until applied by the Administrative Agent as provided
in this Agreement.  Anything in this Agreement

to the contrary notwithstanding, funds standing to the credit of the Collateral
Account shall be subject to withdrawal only as  provided in this SECTION 10.09.

        (c)    Amounts standing to the credit of the Collateral Account shall be
invested and reinvested by the Administrative Agent in such Market Securities
Investments of the type specified in clauses (a), (b) and (c) of the definition
of Market Securities Investments as the Company shall specify to the
Administrative Agent from time to time (provided that the approval of the
Administrative Agent shall be required for investments and reinvestments to be
made during any period while an Event of Default has occurred and is
continuing), which investments and reinvestments shall be held in the Collateral
Account in the name and be under the control of the Administrative Agent.

        (d)    At any time following the occurrence and during the continuance
of an Event of Default, the Administrative Agent may (and, if instructed by the
Majority Banks, shall) in its (or their) discretion at any time and from time to
time elect to liquidate any such investments and reinvestments and credit the
proceeds of any such investments and reinvestments to the Collateral Account and
apply or cause to be applied such proceeds and any other balances standing to
the credit of the Collateral Account to the payment of the obligations of the
Company in respect of the Letters of Credit and thereafter to the other
obligations of the Company under this Agreement and under the Notes.

        (e)    So long as no Event of Default shall have occurred and be
continuing, on any date on which the aggregate amount of funds standing to the
credit of the Collateral Account as cover for Letter of Credit Liabilities
exceeds the aggregate amount of Letter of Credit Liabilities, the Administrative
Agent shall promptly deliver to the Company, against receipt but without any
recourse, warranty or representation whatsoever, that portion of the balance in
the Collateral Account equal to such excess.

time such fees as the Administrative Agent normally charges for similar services
in connection with the Administrative Agent's administration of the Collateral
Account and investments and reinvestments of funds in the Collateral Account.

        10.10  CO-AGENT.  None of the Banks identified on the facing page or
signature pages of this Agreement as a "CO-AGENT"  shall have any right, power,
obligation, liability, responsibility or duty under this Agreement other than
those applicable to all Banks as such.  Each Bank acknowledges that it has not
relied, and will not rely, on any of the Banks so identified in deciding to
enter into this Agreement or in taking or not taking any action under this
Agreement.

        SECTION 11. Miscellaneous.

any Bank to exercise and no delay in exercising, and no course of dealing with

investigation, litigation or other proceedings (including, in respect of the
Administrative Agent, any such investigation, litigation or other proceedings
between the Administrative Agent and any Bank) relating to the extensions of
credit under, and the transactions contemplated by, the Basic Documents or any

Bank and their respective affiliates, directors, officers, employees, attorneys

Agreement, including amendments to ANNEX 1 as a result of the execution and
delivery of an Assignment and Acceptance pursuant to SECTIONS 2.12(b) or

instrument effecting the same and shall be binding upon the Administrative      
Agent, the Banks and the Company, and any such waiver shall be effective only 
in the specific instance and for the purpose for which given.

        Notwithstanding any other provision of this Agreement, if:

        (i)  at a time when the conditions precedent set forth in SECTION 6 to

Bank shall fail to fulfill its obligations to make such Loan; or

        (ii)  any Bank shall fail to pay to the Administrative Agent for the
account of the Issuing Bank the amount of such Bank's Commitment Percentage of
any payment under a Letter of Credit pursuant to SECTION 2.04(e),

then, for so long as such failure shall continue, such Bank shall (unless the
Majority Banks, determined as if such Bank were not a "BANK" under the Basic
Documents, shall otherwise consent in writing) be deemed for all purposes
relating to amendments, modifications, waivers or consents under any of the
Basic Documents (including under this SECTION 11.04 and under SECTION 10.09) to
have no Loans, Letter of Credit Liabilities or  Commitments, shall not be
treated as a "BANK" under the Basic Documents when performing the computation of
Majority Banks, and shall have no rights under the preceding paragraph of this

the matters referred to in clause (a) of the preceding paragraph shall not be
effective as against such Bank.

        11.06  Assignments and Participations.
               -------------------------------

this Agreement or under the Notes without the prior consent of all of the Banks
and the Administrative Agent.

        (b)    Each Bank may assign all or any part of its Loans, its Notes, its
Commitment (which Commitment assignment shall include such Bank's corresponding
obligations to the Swingline Bank and the Issuing Bank under SECTION 2.02(b) and
SECTIONS 7.04(e) and (f), respectively) and its Letter of Credit Interest (but
only with the consent of, in the case of an outstanding Commitment, the Company
and the Administrative Agent, which consents shall not be unreasonably withheld
and, in the case of a Letter of Credit Interest, the Issuing Bank), together
with, in any such case, its related rights, remedies, powers and privileges
under the Basic Documents; PROVIDED that (i) no such consent by the Company, the
Administrative Agent or the Issuing Bank shall be required in the case of any
assignment to another Bank or any of its affiliates; (ii) any such partial
assignment shall be in an amount at least equal to $10,000,000; and (iii) each
such assignment by a Bank of its Loans, Note, Commitment or Letter of Credit
Interest shall be made in such manner so that the same portion of its Loans,
Note, Commitment and Letter of Credit Interest is assigned to the respective
assignee.  Upon execution and delivery by the assignee to the Company, the
Administrative Agent and the Issuing Bank of an Assignment and Acceptance,
pursuant to which such assignee agrees to become a "BANK" under this Agreement
(if not already a Bank) having the Commitment or Commitments, Loans, and, if
applicable, Letter of Credit Interest specified in such instrument, and upon the
consent of the Company, the Administrative Agent and the Issuing Bank, to the
extent required above, the assignee shall have, to the extent of such assignment
(unless otherwise provided in such assignment with the consent of the Company,
the Administrative Agent and the Issuing Bank), the obligations, rights and
benefits of a Bank under the Basic Documents holding the Commitment or

or Commitments, Loans and Letter of Credit Interest, if any, held by such
assignee prior to the date of such assignment) and the assigning Bank shall, to
the extent of such assignment, be released from the Commitment or Commitments so
assigned.  ANNEX 1, setting forth the Commitments of the Banks, shall be
automatically amended as of the execution and delivery of each Assignment and
Acceptance to reflect the change in the Banks and the Commitments occurring as a
result of the delivery of each such Assignment and Acceptance.  Promptly after
the delivery of each Assignment and Acceptance, the Administrative Agent shall  
deliver a copy of the amended ANNEX 1 to the Company and each of the Banks. 
Upon each such assignment the assigning Bank shall pay the Administrative Agent
an assignment fee of $2,500.

        (c)    A Bank may sell or agree to sell to one or more other Persons a
participation in all or any part of its Loans, its Notes, its Commitment, its
Letter of Credit Interest and its related rights, remedies, powers and
privileges under the Basic Documents, in which event each purchaser of a
participation (a "PARTICIPANT") shall be entitled to the rights and benefits of
the provisions of SECTION 8.01(k) with respect to such participation as if (and
the Company shall be directly obligated to such Participant under such
provisions as if) such Participant were a "BANK" for purposes of SECTION
8.01(k), but, except as otherwise provided in SECTION 4.07(c), shall not have
any other rights, remedies, powers or privileges under any Basic Document (the
Participant's rights against such Bank in respect of such participation to be
those set forth in the agreements executed by such Bank in favor of the
Participant).  All amounts payable by the Company to any Bank under SECTION 5 in
respect of such Bank's Loans, Notes, Letter of Credit Interest, and Commitments
shall be determined as if such Bank had not sold or agreed to sell any
participations in such Loans, Notes, Letter of Credit Interest and Commitments,
and as if such Bank were funding each of such Loans, Letter of Credit Interest
and Commitments in the same way that it is funding the portion of such Loans,
Letter of Credit Interest and Commitments in which no participations have been
sold.  In no event shall a Bank that sells a participation agree with the
Participant to take or to refrain from taking any action under any Basic
Document except that such Bank may agree with the

(i) increase or extend the term, or extend the time or waive any requirement for
the reduction or termination, of such Bank's related Commitment, (ii) extend the
date fixed for the payment of principal of or interest on the   related Loan or
Loans, Reimbursement Obligations or any portion of any fee under this Agreement
payable to the Participant, (iii) reduce the amount of any such payment of
principal, (iv) reduce the rate at which interest or any fee under this
Agreement in which such Bank has sold an interest is payable to the Participant,
to a level below the rate at which the Participant is entitled to receive such
interest or fee under its agreements with such Bank, (v) alter the rights or
obligations of the Company to prepay the related Loans or (vi) consent to any
modification, supplement or waiver of any Basic Document to the extent that the
same, under SECTION 10.09 or SECTION 11.04, requires the consent of each Bank.

        (d)    In addition to the assignments and participations permitted under
the foregoing provisions of this SECTION 11.06, any Bank may assign and pledge

        Closing as provided in SECTIONS 9 AND 10.

        (c)   "CODE" shall mean the Internal Revenue Code of 1986 and all

        the financial condition of Seller as of such date in accordance with
        generally accepted accounting principles and actuarial reserving
        practices consistently applied with those used in the preparation of the
        1994 Balance Sheet and applying the Special Accounting Principles

        arbitrator.  The decision of the arbitrator shall be final and binding
        on Seller and Buyer.  Seller and Buyer shall share equally the fees and
        expenses of the arbitrator.  The resulting balance sheet shall be
        binding on both parties and shall form the basis for preparation and
        delivery by Seller at Closing of the Estimated Balance Sheet, which
        shall be prepared in a manner consistent with the Proposed Estimated
        Balance Sheet (as modified by agreement of Seller and Buyer and by

        unqualified opinion and report (with standard footnotes) of KPMG Peat
        Marwick, LLP upon such statements prepared in accordance with

        be prepared in compliance with SEC Rule S-X in form for filing with the
        SEC and coupled with the consent of KPMG Peat Marwick, LLP to being
        named as experts and to the use of their reports in such filing.  All

        shall mean any event, occurrence or matter having a material adverse
        effect on the business, operations, property, results of operations,
        financial condition or prospects of Seller or the HMO Business,
        including but not limited to failure to negotiate and enter into the
        hospital services agreement with the Medical Center of Central
        Massachusetts ("MCCM") referred to in SECTION 18 on the terms and       
        conditions specified in EXHIBIT J for all members of Seller and its

        Deloitte & Touche, LLP shall be given a reasonable opportunity to review
        the 1994 Balance Sheet in draft form before it  is finalized (including
        all work papers of KPMG Peat Marwick, LLP actuarial assumptions and 


                                       4

        calculations).  In the event Buyer and Buyer's independent accountants,

        Seller and KPMG Peat Marwick, LLP within one week of the receipt of all
        such papers and shall attempt to resolve such dispute.  If the parties
        are unable to resolve the dispute within fifteen (15) business days
        after Buyer's receipt of all papers from KPMG Peat Marwick, LLP,
        Deloitte & Touche, LLP and KPMG Peat Marwick, LLP shall select a third
        nationally recognized accounting firm to act as arbitrator of the
        dispute and such firm shall resolve the dispute within fifteen (15)
        business days after such dispute is referred to such arbitrator.  The
        decision of the arbitrator shall be final and binding on Seller and
        Buyer.  Seller and Buyer shall share equally the fees and expenses of
        the arbitrator.  The resulting balance sheet shall be binding on both
        parties and shall be the "1994 Balance Sheet."

        (i)  "SPECIAL ACCOUNTING PRINCIPLES" shall mean the following Special
        Accounting Principles which shall apply to the specific financial
        statements required by this Agreement, where these Special Accounting
        Principles are specifically referenced:  (i) there shall be included not
        only incurred but unbilled services but also a full accrual for
        completion of hospitalization existing on the end of the accounting
        period (hereafter the "Full Accrual Principle"); and (ii) for purposes
        of preparation of any balance sheet and any income statement, activities
        outside of the ordinary business and investment activities of any kind
        shall be eliminated to remove any effect that would increase the income
        or net worth in said calculations, for example and without limitation,
        any net gain (after deducting any losses from the sale of appreciated
        securities or other capital assets) shall be excluded from the
        calculations, as well as the income tax related to such net gain, but
        this shall not have any impact on interest or dividend income as
        normally accounted for by Seller's accounting policies.

        (j)  "TAXES" shall mean all federal, state, local, foreign, and other
        net income, gross income, gross receipts, sales, use, ad valorem,
        transfer, franchise, profits, license, lease, service, service use,
        withholding, payroll, employment, excise, severance, stamp,

vendors), subrogation rights (including without limitation, assets realized as a
result thereof), confidential or proprietary information, prepayments, deferred

(or any assets thereof) or any notes receivable or other obligations of
Worcester Surgical Center, Inc. to Seller or other assets of Seller relating to
the Worcester Surgical Center.  The business being transferred is referred to
herein as the "HMO Business" and the assets being transferred are referred to
herein as the "Assets".  Buyer shall assume the HMO Business pursuant to an
Assumption Reinsurance Agreement approved by the Massachusetts Division of
Insurance, in the form attached hereto as EXHIBIT A.  A computer generated
schedule of all such existing assets having an individual book value of more
than $1,000 is attached as SCHEDULE 6.08.

        2.02 EMPLOYMENT MATTERS.  In connection with the acquisition of the HMO
Business, Buyer, at Closing, shall hire Seller's current employees engaged in
the conduct of  Seller's business (hereinafter the "Transferred Employees") at
salaries comparable to those disclosed under SECTION 6.14.  It is the current
intention of Buyer to retain Seller's workforce after Closing at salaries and
with benefits substantially similar to those provided by Seller to such
employees on the Closing Date; it being understood and agreed that this
representation does not confer any rights of continued employment upon any such
Transferred Employee other than that of an employee-at-will.  After Closing,
employees of Seller who accept employment with Buyer shall be eligible to
receive those salary and other benefits as shall be applicable from 

                                       6
<PAGE>   7

time to time to other employees of Buyer holding comparable positions.  At
Closing Buyer shall also assume all obligations of Seller under the     
agreements with certain key employees as disclosed in SCHEDULE 2.02.

        2.03 EMPLOYEE BENEFITS.  Seller's current employees are presently
participating in the benefit plans listed in SCHEDULE 6.24 (collectively the
"Employee Benefit Plans").  As of the day prior to Closing,  Seller shall
terminate the participation of Seller's employees in the Employee Benefit Plans
and Seller shall be entirely responsible for administering and reporting each
such termination as well as providing such notices of vested rights or payments,
if any, to each such participant as are required by law and shall hold Buyer
harmless from any liability occasioned by such termination or arising from such
employees prior participation in the Employee Benefit Plans.  After Closing
Seller's employees shall participate in the benefit plans of Buyer.

        2.04 PHYSICAL FACILITIES/OFFICE FURNITURE AND EQUIPMENT.  Seller
currently leases office space in Worcester, Massachusetts from Worcester Center
Realty Trust under a lease expiring October 31, 1999.  Seller shall cause an
assignment of said lease to Buyer at Closing and shall deliver to Buyer an
estoppel certificate from the lessor of such property.
   
        2.05 ASSIGNMENT OF CONTRACTS.  At Closing Seller shall assign to Buyer
all contracts listed on SCHEDULE 2.05A and all other contracts used in Seller's
business which Buyer elects to assume at Closing and shall secure all necessary
consents to the assignment of such assigned and assumed contracts; including

3.      PURCHASE PRICES; METHOD OF PAYMENT; ALLOCATION.

        3.01  PURCHASE PRICE.  In consideration of the transfer of the Assets
and Seller's Non-Competition Covenant referred to in SECTION 11, Buyer shall pay
to Seller at Closing an amount (the "Adjusted Purchase Price") equal to the base
purchase price of Sixty Two Million Five Hundred Thousand Dollars ($62,500,000)
(the "Base Purchase Price) as adjusted in accordance with the provisions of
SECTION 4, calculated as reflected on SCHEDULE 4.01.

        3.02 METHOD OF PAYMENT.  Buyer shall make payment at Closing of the net
amount due Seller after any adjustments, credits and pro-rations by wire
transfer to Seller's bank.  Notwithstanding the above, Buyer may elect to retain
a portion of the Adjusted Purchase Price to offset Seller's obligation to
deliver the Acceptable Financial Assets at book value and such cash retained by
Buyer shall be deemed to be part of the Acceptable Financial Assets delivered by
Seller to Buyer.  Seller may elect to retain certain Acceptable Financial Assets
at book value and Buyer may retain a portion of the Purchase Price to offset
Seller's obligation to deliver such Acceptable Financial Assets; such cash
retained by Buyer shall be deemed to be part of the Acceptable Financial Assets
delivered by Seller to Buyer.

        3.03 ALLOCATION OF PURCHASE PRICE.  The purchase price for the Assets
shall be allocated by Buyer; Seller shall cooperate with Buyer in the filing of
all forms and reports necessary to effect such allocation.

        3.04 SELLER'S LIABILITIES.  Seller shall assume, bear and seasonably
satisfy all of its expenses, debts and liabilities including without limitation,
contractual claims, claims of employees, claims against any affiliate, director,

care expenses, and commissions on a fully accrued basis arising from the conduct
of the HMO Business through Closing and any and all activities performed (or not
performed) prior to Closing (including without limitation any liability relating
to or arising from the matters listed on SCHEDULE 3.04 attached hereto), it is
agreed that Buyer assumes none of such liabilities, whether known or unknown,
nor however arising, except for any such liabilities which are specifically
reflected in the Estimated Balance Sheet or the Final Balance Sheet and only to
the extent Buyer received effective credits for same in calculating the tangible
minimum net worth referred to under SECTION 4.01(a) and 4.02.  Moreover, Buyer
shall not assume any liabilities whatsoever in any way relating to (i) 300 Grove
Street Realty Corp., Worcester Surgical Center, Inc. or the Somerset/Worcester
MRI Limited Partnership; or (ii) the Physician Withholds defined in SECTION 2.09
which Seller shall pay to its participating physicians at or prior to
Closing to the extent permitted in SECTION 2.09.

4.   PURCHASE PRICE CREDIT AND POST-CLOSING ADJUSTMENT;
     PRO-RATIONS.

     4.01 PURCHASE PRICE CREDITS.
          -----------------------

          (a)  CHANGES IN TANGIBLE NET WORTH.  If the tangible net worth
          (Fund balances) of Seller as reflected on the Estimated Balance
          Sheet at Closing is less than $18,200,000, Buyer shall receive a
          purchase price credit equal to the difference between such
          tangible net worth as reflected on the Estimated Balance Sheet
          and $18,200,000, subject to offset by the "1995 Losses Offset" as
          defined in SECTION 4.01(b).  If the tangible net worth of Seller
          as reflected on the Estimated Balance Sheet at Closing is greater
          than $18,200,000, Buyer will pay such excess to Seller at
          Closing.  Seller and Buyer acknowledge and agree that all
          amounts, if any, paid or to be paid by Seller to physicians prior
          to or at Closing for return of Physician Withholds as permitted
          by SECTION 2.09 shall be deducted from the "Risk fund" line item
          of the Estimated Balance Sheet and Final Balance Sheet (which
          will have the effect of reducing the Seller's total "Fund
          balances" shown in such Estimated Balance Sheet and Final Balance
          Sheet).

          (b)  1995 LOSSES OFFSET.  For purposes of determining any
          purchase price credit or adjustment, if any, under SECTIONS
          4.01(a) and 4.02(a), in the event that Seller's tangible net
          worth as of the Closing Date is less than $18,200,000 (for
          reasons other than as a result of the payment of the Physician
          Withholds), Seller shall be entitled to offset amounts otherwise
          due to Buyer as a result of any such shortfall from $18,200,000
          incurred in the period from January 1, 1995 through the date of
          Closing by up to $1.5 

                                       9
<PAGE>   10

          million in operating losses incurred by Seller during such period 
          (January 1, 1995 through the date of Closing).

     (c)  EXCLUSION OF NON-HMO BUSINESS ASSETS.  As provided in SECTIONS
          2.01 and 3.04, Seller and Buyer agree that all assets and
          liabilities and any operational responsibilities relating to 300
          Grove Street Realty Corp., Worcester Surgical Center, Inc. and
          the Somerset/Worcester MRI Limited Partnership (hereinafter the
          "Non-HMO Business Assets) will be retained by Seller.  The
          Adjusted Purchase Price shall in all cases be determined by
          excluding therefrom the value of the Non-HMO Business Assets of
          Seller as reflected on the Estimated Balance Sheet and the Final
          Balance Sheet.

     4.02 POST-CLOSING ADJUSTMENTS.
          -------------------------

          (a)  FINAL BALANCE SHEET ADJUSTMENT.  Seller will, within 45 days
          after the Closing Date, deliver to Buyer a proposed final balance
          sheet of Seller as of the Closing Date ("Proposed Final Balance
          Sheet") which presents fairly the financial condition of Seller
          as of the Closing Date in accordance with generally accepted
          accounting principles and actuarial reserving practices
          consistently applied with those used in the preparation of the
          Estimated Balance Sheet and the 1994 Balance Sheet (and applying
          the Special Accounting Principles), together with the unqualified
          opinion of KPMG Peat Marwick, LLP prepared in accordance with
          generally accepted auditing standards as modified by the Special
          Accounting Principles.  Buyer's independent accountants, Deloitte
          & Touche, LLP shall be given a reasonable opportunity to review
          the Proposed Final Balance Sheet in draft form before it is
          finalized (including all work papers of KPMG Peat Marwick, LLP
          actuarial assumptions and calculations).  In the event Buyer and
          Buyer's independent accountants, Deloitte & Touche, LLP dispute
          the Proposed Final Balance Sheet, they shall notify Seller and
          KPMG Peat Marwick, LLP within two weeks of the receipt of all
          such papers and shall attempt to resolve such dispute.  If the
          parties are unable to resolve the dispute within fifteen (15)
          business days after Buyer's receipt of all papers from KPMG Peat
          Marwick, LLP Deloitte & Touche, LLP and KPMG Peat Marwick, LLP
          shall select a third nationally recognized accounting firm to act
          as arbitrator of the dispute and such firm shall resolve the
          dispute within fifteen (15) business days after such dispute is
          referred to such arbitrator.  The decision of the arbitrator
          shall be final and binding on Seller and Buyer.  Seller and Buyer
          shall share equally the fees and expenses of the arbitrator.  The
          resulting balance sheet shall be binding on both parties and
          shall be the "Final Balance Sheet."  To the extent that the Final
          Balance Sheet reflects tangible net worth of 


                                      10
<PAGE>   11

          Seller as of the Closing Date of less than $18,200,000, Seller shall
          pay the difference (adjusted for any prior adjustment to the purchase
          price received by Buyer or Seller pursuant to SECTIONS 4.01(a) and
          4.01(c) above and the 1995 Losses Offset of SECTION 4.01(b) above). 
          If the tangible net worth of Seller as of the Closing Date as
          reflected on the Final Balance Sheet is greater than $18,200,000
          (including without limitation by reason of there being IBNR
          reserves in excess of that which would be required in accordance with
          generally accepted accounting and actuarial reserving practices
          consistent with past practices of Seller) such difference will be paid
          by Buyer to Seller (adjusted for any prior adjustment to the purchase
          price received by Buyer or Seller pursuant to SECTION 4.01(a) above).

          (b)  UPDATED FINAL BALANCE SHEET IBNR ADJUSTMENT.  Within 45 days
          after June 30, 1996, Buyer shall deliver to Seller an audited
          updated Final Balance Sheet of  Seller's HMO Business as of the
          Closing Date prepared in accordance with generally accepted
          accounting principles and actuarial reserving practices
          consistently applied with those used in the preparation of the
          Final Balance Sheet (including the Special Accounting
          Principles), reviewed by Buyer's auditors ("Updated Final Balance
          Sheet"), which takes into account actual payments after Closing
          for claims for health care incurred but not reported ("IBNR")
          through the date of Closing along with an appropriate accrual for
          any remaining IBNR ("Actual IBNR").  If Actual IBNR as reflected
          in the Updated Final Balance Sheet is different from IBNR
          reported in the Final Balance Sheet, Seller will pay the
          difference to Buyer if such Actual IBNR is greater than the Final
          Balance Sheet IBNR and Buyer will pay the difference to Seller if
          such Actual IBNR is less than the Final Balance Sheet IBNR.

          (c)  PAYMENTS; INTEREST.  Any post-closing payments pursuant to
          this Section 4.02 shall be paid within five (5) days of
          determination as provided in Sections 4.02(a) or (b), along with
          interest thereon from the Closing Date at the Prime Rate as
          defined in Section 13.  

     4.03 CLOSING PRO-RATIONS.  The following items shall be adjusted at
Closing:

          (a)  To the extent that such amounts have not been reflected as
          liabilities on the books of Seller, Seller shall pay to Buyer at
          Closing those amounts representing unearned prepaid premiums on
          all health care benefits provided by Seller.

                                      11
<PAGE>   12

          (b)  Final payroll for all Transferred Employees shall be
          pro-rated between Seller and Buyer based upon the working days
          attributable to each to Closing.  Based upon Seller's vacation,
          sick leave and personal day policy now in effect, an appropriate
          accrual shall be made for all vacation leave, sick leave and
          personal days earned through Closing and Seller shall pay such
          amount to Buyer at Closing and Buyer shall assume Seller's
          obligations for such vacation, sick leave and personal days.

conditions, standards, prohibitions, requirements, obligations, schedules
and timetables contained in those laws or contained in any regulation,
code, plan, order, decree, judgment, notice or demand letter issued,
entered, promulgated or approved thereunder.  There are no past, present
or, so far as Seller can reasonably foresee, future events,  conditions,
circumstances, activities, practices, incidents, actions or plans which may

agreements), with respect to all taxable periods or portions of periods
ending on or before Closing, all applicable tax laws and agreements have
been fully complied with, and all such amounts required to be paid by
Seller to taxing authorities or others on or before the date hereof have

pending before), and no proceedings are currently pending before, any
taxing authority in connection with any of the Returns relating to Seller.

               fact occur in conformity with this SECTION 8.01.  No such
               disclosure shall have any effect for the purpose of determining
               the satisfaction of the conditions set forth in SECTION 10
               hereof.

               modify, terminate or assume any contract, lease, license or
               commitment which by its terms requires performance subsequent to
               the Closing Date except for such matters which are within the
               normal and ordinary course of business or which involve an annual
               monetary commitment or exposure of not more than $10,000 each or
               $100,000 in the aggregate, provided, however, that Seller will

               customarily employed by Seller in the past in writing new
               business and unless any such HMO contract is reasonably expected
               to generate revenues sufficient to meet anticipated obligations
               and a margin for profit consistent with Seller's average margin
               on such products, in the case of new business, and consistent
               with the margin on the specific account in the prior year, if
               renewal business; provided, further, that if Seller believes that
               any proposed non-complying contract would be advisable in order

               contracts and products in the same lines as such HMO contracts on
               behalf of Buyer and its affiliates.

Agreement have not been consummated on or prior to September 30, 1995 or
