                   NOTES TO CONSOLIDATED FINANCIAL STATEMENTS

                                 MARCH 31, 1999
                                   (Unaudited)

NOTE 1 - BASIS OF PRESENTATION:

        The accompanying unaudited financial statements reflect all adjustments
(consisting of normal, recurring accruals only) which are necessary to fairly
present the results for the interim periods. Such financial statements have been
prepared in accordance with the instructions to Form 10-Q and Rule 10-01 of
Regulation S-X and therefore do not include all the information or footnotes
necessary for a complete presentation. They should be read in conjunction with
the Company's Annual Report on Form 10-K for the year ended June 30, 1998 and
the notes thereto. The results of operations for the nine months ended March 31,
1999 are not necessarily indicative of results for the full year.

NOTE 2 - INCOME TAXES:

        Income taxes have been computed based on the estimated annual effective
income tax rate for the respective years.

NOTE 3 - OTHER ASSETS:

        On August 1, 1998, the Company acquired the weather observation and
forecasting and air traffic control government contracts and related assets of
Weather Data Services, Inc. for $3,500,000, which consisted of $2,500,000 in
cash and $1,000,000 of the Company's stock. The purchase price has been
allocated to intangible assets including contracts and goodwill.

NOTE 4 - LONG-TERM DEBT:

On March 2, 1999, the company entered into an $80,000,000 senior secured credit
facility with a consortium of four banks. This facility includes up to
$40,000,000 Revolving Credit ("Revolving Credit"), a term loan of up to
$25,000,000 ("Term Loan") and an acquisition facility of up to $15,000,000
("Acquisition Facility"). These facilities mature in March 2004. The Term Loan
is payable over five years in quarterly installments of principal of $1,000,000
in year one with quarterly installments increasing each year thereafter by
$125,000 with a final installment in March 2004. Balances outstanding under the
Revolving Credit and Acquisition Facility will be due in March 2004. Interest
rates may vary depending upon the Company's leverage ratio, however, the cost
will initially be Eurodollar rate plus 1.75% or the Banks base rate (equivalent
to the prime rate). Amounts funded at the closing date were $24,000,000 under
the Term Loan, which was used to repay outstanding principal of approximately
$16,833,000 under the old senior credit facility; repay principal under various
other notes of approximately $6,474,000; pay accrued interest, letter of credit
fees and closing fees totalling approximately $466,000; and the balance of
$227,000 received in cash. At March 31, 1999 current portion of long-term debt
pertaining to this facility is $4,000,000 and long-term debt includes
$20,000,000 of the Term Loan and $2,000,000 of Revolving Credit

NOTE 5- EARNINGS PER SHARE:

        Basic income (loss) per common share is computed by dividing net
income by the weighted average number of common shares outstanding during the
period. Diluted income (loss) per share is computed by dividing net income by
the weighted average number of common shares and common stock equivalents.
Common stock equivalents include stock options and shares resulting from the
assumed conversion of subordinated debentures, when dilutive.

Income." This statement, which the Company adopted in fiscal 1999, establishes
standards for reporting and displaying comprehensive income and its components
in a full set of financial statements. For the periods presented, adjustments to

THREE MONTHS ENDED  MARCH 31, 1999 COMPARED TO MARCH 31, 1998.

Revenue increased by 1.8% to $53.6 million in the current period from $52.7
million a year ago. Gross margin increased 11.8% to $7.4 million in the current
period from $6.6 million a year ago.

Revenues from fuel sales and services represented 52.4% of total revenues in the
current period compared to 61.3% of total revenues a year ago. Revenues from
fuel sales and services fell 12.9% to $28.1 million from $32.3 million last
year. The decline in revenues from fuel sales and services was due to a decrease
in the price of fuel. Gross margin from fuel sales and service increased by
35.5% to $2.4 million in the current period from $1.8 million last year due to
higher per gallon fuel margins. Revenues and operating income from fuel sales
and services include the activities of Mercury's contract fueling business, as
well as activities from a number of other commercial services including the
provision of certain refueling services, non-aviation fuel brokerage and other
services managed at LAX as part of Mercury's fuel sales and services operations.
In addition, fuel sales and services include the activities of Mercury's
wholly-owned subsidiary, Rene Perez and Associates, Inc. ("RPA"), subsequent to 
its acquisition in February 1998. RPA is a developer of accounting and
management information software products for the aviation business. Revenue from
RPA was $982,000 in the current period compared to $410,000 in the year ago
period.

Revenues from FBOs increased by 10.0% in the current period to $12.2 million
from $11.1 million a year ago. Gross margin increased 7.4% in the current period
to $2.8 million from $2.6 million last year. The increase was attributable to an
increase in the number of gallons sold and higher per gallon fuel margins. Gross
Margin as a percentage of revenue decreased to 23.0% in the current period from
23.6% a year ago due to higher costs associated with the new Burbank facility
and start up costs of the new Charleston facility.

Revenues from cargo operations in the current period increased 32.8% to $7.0
million from $5.3 million a year ago. This increase was primarily due to an
increase in cargo handling revenues at LAX and Atlanta. Gross margin from cargo
operations in the current period decreased 13.3% to $1.0 million from $1.1
million in the year ago period primarily due to losses in the Miami cargo
handling division. The Miami division was divested in March 1999.

Revenues from government contract services increased 56.1% in the current period
to $6.3 million from $4.0 million in the year ago period. The increase in
revenues from government contract services was due primarily to the addition of
the Weather Data contracts as of August 1, 1998. Gross margin from government
contract services in the current period increased 9.0% to $1.2 million from $1.1
million last year due to higher revenues. Gross margin as a percentage of
revenues declined as a result of lower margins derived from Weather Data's
contracts.

Selling, general and administrative expenses in the current period increased
15.8% to $1.9 million from $1.6 million in last year's period due primarily to
higher compensation expense.

Depreciation and amortization expense increased 67.7% in the current period to
$2.1 million from $1.3 million a year ago primarily due to the LAX Cargo
warehouse expansion during fiscal 1998, the Burbank FBO expansion completed in
this period, acquisitions during the past twelve months and continuing capital
expenditures.

Interest expense increased 23.0% in the current period to $1.1 million from
$.894 million a year ago due to higher average outstanding borrowings under the
Company's Senior Secured credit facility.

Income tax expense approximated 39.1% of pre-tax income in the current period
and 39.6% of pretax income a year ago reflecting the expected effective annual
income tax rates.

In the current three month period, extraordinary item of $68,000 consists of a
charge of $111,000 related to the cost of repurchasing convertible subordinated
debentures in excess of par value plus related bond issuance costs, net of the
related income tax benefit of $43,000.

 NINE MONTHS ENDED MARCH 31, 1999 COMPARED TO MARCH 31, 1998.

Revenues decreased 14.5% to $162.9 million in the current period from $190.5
million a year ago due to a decrease in fuel sales, caused by a decline in the
price of fuel and a decrease in volume sold, a significant portion of which was
due to the loss of Western Pacific's fuel business. Gross Margin increased 9.4%
to $22.9 million in the current period from $21.0 million a year ago.

Revenues from fuel sales and services represented 54.4% of total revenues in the
current period compared to 67.3% of total revenue a year ago. Revenues from fuel
sales and services decreased 30.9% to $88.6 million from $128.4 million last
year. The decrease in revenues from fuel sales and services was primarily due to
a decrease in the price of fuel and a decrease in the volume of fuel sold, a
significant portion of which was due to the loss of Western Pacific's fuel
business. Gross margin from fuel sales and services increased 17.7% in the
current period to $7.2 million from $6.2 million a year ago. The increase in
gross margin from fuel sales and services in the current period compared to last
year was attributable to higher fuel margins and RPA's contribution. Revenue
from RPA was $4,708,000 in the current nine month period compared with
$410,000 in the year ago period (one month only).

Revenue from FBOs increased 4.8% in the current period to $35.4 million from
$33.7 million a year ago. Gross margin increased 18.1% to $8.3 million from $7.0
million in the year ago period due to an increase in gallons sold and higher per
gallon fuel margins. During fiscal 1999, FBOs include the activities of 
Charleston which opened in November 1998 and Jackson which was acquired on
November 30, 1998.

Revenues from cargo operations in the current period increased 26.9% to $20.5
million from $16.1 million a year ago. The increase was primarily due to an
increase in cargo handling revenue at LAX and Atlanta and partially offset by a
decline in space brokerage revenue, which decline was attributable in part to
soft Asian economies. Gross margin from cargo operations in the current period
decreased 21.3% to $3.6 million from $4.6 million in the year ago period due to
increased losses in Miami and lower space brokerage revenue. The Company
divested its Miami cargo handling operation in March 1999.

Revenues from government contract services in the current period increased 49.3%
to $18.4 million from $12.3 million in the year ago period. The increase in
revenues from government contract services in the current period compared to
last year was primarily due to the addition of the Weather Data contracts as of
August 1, 1998. Gross margin from government contract services in the current
period increased 17.9% to $3.8 million from $3.2 million last year due to higher
revenues.

Selling general and administrative expenses in the current period increased
15.1% to $5.2 million from $4.5 million in the year ago period. The increase was
primarily due to higher compensation expense.

Depreciation and amortization expense in the current period increased 59.0% to
$5.8 million from $3.7 million a year ago. The increase in the current period is
primarily related to the new LAX cargo warehouse added during fiscal 1998, the
new Burbank FBO expansion completed in February 1999 and acquisitions during the
past twelve months together with capital expenditures.

Interest expense increased 18.0% in the current nine months to $3.1 million from
$2.6 million a year ago due to higher average outstanding borrowings. Interest
income decreased 69.1% in the current nine months to $154,000 from $498,000 in
the year ago period due to lower average balances of notes receivable and
invested cash.

Loss resulting from the bankruptcy of a customer was $7,050,000 in the year ago
period and was related to the bankruptcy filing by Western Pacific Airlines,
Inc. (WPAI) on October 5, 1997. The charge included a $5 million reduction in
restricted cash and approximately $2,050,000 write off of WPAI's account
receivable. The restricted cash consisted of pledged certificates of deposits
which guaranteed bank loans to WPAI.

Income tax expense approximated 39.0% of pretax income in the current period and
39.5% of pretax income a year ago, reflecting the expected effective annual
income tax rates.


In the current nine month period, extraordinary item of $255,000 consists of a
charge of $418,000 related to the cost of repurchasing and retiring the
convertible subordinated debentures in excess of par value plus related bond
issuance costs, net of the related income tax benefit of $163,000.

LIQUIDITY AND CAPITAL RESOURCES:

Mercury has historically financed its operations primarily through operating
cash flow, bank debt, the $19 million tax exempt CEDFA bonds issued in 1998 and
the $28 million of convertible subordinated debentures issued in 1996. Mercury's
cash balance at March 31, 1999 was $2,935,000.

Net cash provided by operating activities totaled $5,919,000 during the nine
month period ended March 31, 1999. During this period, the primary sources of
net cash provided by operating activities was net income and depreciation and
amortization totalling $10,194,000. The primary use of cash from operating
activities was an increase in accounts receivable of $5,230,000. Accounts
receivable at March 31, 1999 increased from June 30, 1998 balances due to higher
sales in the quarter versus the June quarter. Days sales outstanding were
approximately 71 at March 31, 1999 versus approximately 70 at June 30, 1998.

Net cash used in investing activities was $9,922,000 during the current nine
month period. The primary source of cash from investing activities included a
reduction of $7,248,000 in restricted cash related to the construction of the
new Burbank fixed base operation. The primary use of cash from investing
activities included additions to property, equipment and leaseholds of
$13,110,000 and acquisition of businesses, net of cash acquired, of $4,200,000.

Net cash used in financing activities was $898,000 during the current nine month
period. The primary use of cash from financing activities was a reduction in
long-term debt of $16,676,000, the reduction in convertible subordinated
debentures of $5,555,000 and repurchases of 641,781 shares of common stock
totaling $4,682,000. The primary source of cash from financing activities was
proceeds from long-term debt of $26,000,000 related to the new Term Loan and
Revolving Credit.

On March 2, 1999, the company entered into an $80,000,000 senior secured credit
facility with a consortium of four banks. This facility includes up to
$40,000,000 Revolving Credit ("Revolving Credit"), a term loan of up to
$25,000,000 ("Term Loan") and an acquisition facility of up to $15,000,000
("Acquisition Facility"). These facilities mature in March 2004. The Term Loan
is payable over five years in quarterly installments of principal of $1,000,000
in year one with quarterly installments increasing each year thereafter by
$125,000 with a final installment in March 2004. Balances outstanding under the
Revolving Credit and Acquisition Facility will be due in March 2004. Interest
rates may vary depending upon the Company's leverage ratio, however, the cost
will initially be Eurodollar rate plus 1.75% or the Banks base rate (equivalent
to the prime rate). Amounts funded at the closing rate were $24,000,000 under
the Term Loan, which was used to repay outstanding principal of approximately
$16,833,000 under the old senior credit facility; repay principal under various
other notes of approximately $6,474,000; pay accrued interest, letter of credit
fees and closing fees totalling approximately $466,000; and the balance of
$227,000 received in cash. At March 31, 1999 current portion of long-term debt
pertaining to this facility is $4,000,000 and long-term debt includes
$20,000,000 of the Term Loan and $2,000,000 of Revolving Credit.

Absent a major prolonged surge in oil prices or a capital intensive acquisition,
the Company believes its operating cash flow, revolver, vendor credit and cash
balance will provide it with sufficient liquidity during the next twelve months.
In the event that fuel prices increase significantly for an extended period of
time, the Company's liquidity could be adversely affected unless the Company is
able to increase vendor credit or increase lending limits under its revolving
credit facility. The company believes, however, its revolver and vendor credit
should provide it with sufficient liquidity in the event of a major temporary
surge in oil prices.

The Company has the following significant contracts or commitments for the
purchase of equipment or installation of facilities. The Company has entered
into a new lease with respect to its Burbank, California FBO. Pursuant to the
terms of the lease, the Company is constructing new hangers and an executive
terminal and refurbishing some of its existing hangers at a cost of
approximately $9.0 million. The Company's lease has been extended through April
2025. As of March 31, 1999, the Company has spent approximately $8.6 million on
this project. The Company has also retrofitted or replaced a number of fuel
farms during fiscal 1999 in order to be compliant with government requirements
at a cost of approximately $3,100,000. Amounts drawn down in connection with the
CEDFA bond financing have been used to finance the Burbank FBO construction
while existing lines of credit financed the fuel farm modifications and
improvements.

YEAR 2000 ISSUE

The Company has established a year 2000 compliance plan which is substantially
complete. The compliance program primarily involves information technology,
facilities and equipment and major suppliers of jet fuel. To date, the Company
has spent less than $100,000 and the total estimated cost related to year 2000
compliance is approximately $100,000.

The Company has substantially completed a year 2000 compliance program for
information technology and is currently in the testing phase. All required
information technology changes are anticipated to be operational by the third
quarter of 1999. The Company does not believe that year 2000 issues affecting
its facilities and equipment are substantial. The Company, however, conducts
most of its business on airport properties and, as such, is dependent on various
third parties to complete aspects of year 2000 compliance which will ensure that
airport operations are not significantly impacted or interrupted. While the
Company has no reason to believe that year 2000 compliance by these third
parties will not be substantially completed on time, the Company can give no
assurance to that effect. With respect to major suppliers, the Company believes
year 2000 compliance issues will not affect its ability to continue purchasing
jet fuel in sufficient quantities, given the number of alternative sources.

No contingency plans have been developed for information technology since the
Company believes that its compliance program will be completed timely.

Borrower and the Borrower may borrow, repay and reborrow from time to time
between the Closing Date and the Maturity Date upon notice by the Borrower to
the Agent given in accordance with Section 2.6, such sums as are requested by

Commitment minus such Bank's Revolving Credit Commitment Percentage of the sum

sum of the outstanding amount of the Revolving Credit Loans (after giving effect

Commitment Fee Rate then in effect on the average daily amount during each
calendar quarter or portion thereof from the Closing Date to the Maturity Date
by which the Total Revolving Credit Commitment minus the sum of the Maximum
Drawing Amount and all Unpaid Reimbursement Obligations exceeds the outstanding
amount of Revolving Credit Loans during such calendar quarter. The Revolving
Credit Commitment Fee shall be payable quarterly in arrears on the first day of
each calendar quarter for the immediately preceding calendar quarter commencing
on the first such date following the date hereof, with a final payment on the
Maturity Date or any earlier date on which the Revolving Credit Commitments
shall terminate.

        2.3. REDUCTION OF TOTAL REVOLVING CREDIT COMMITMENT. The Borrower shall
have the right at any time and from time to time upon five (5) Business Days
prior written notice to the Agent to reduce by $1,000,000 or an integral
multiple thereof or terminate entirely the Total Revolving Credit Commitment,
whereupon the Revolving Credit Commitments of the Banks shall be reduced pro
rata in accordance with their respective Revolving Credit Commitment Percentages
of the amount specified in such notice or, as the case may be, terminated.
Promptly after receiving any notice of the Borrower delivered pursuant to this
Section 2.3, the Agent will notify the Banks of the substance thereof. Upon the
effective date of any such reduction or termination, the Borrower shall pay to
the Agent for the respective accounts of the Banks the full amount of any
Revolving Credit Commitment Fee then accrued on the amount of the reduction. No
reduction or termination of the Revolving Credit Commitments may be reinstated.

evidenced by separate promissory notes of the Borrower in substantially the form
of Exhibit A-1 hereto (each a "Revolving Credit Note"), dated as of the Closing
Date and completed with appropriate insertions. One Revolving Credit Note shall
be payable to the order of each Bank in a principal amount equal to such Bank's
Revolving Credit Commitment or, if less, the outstanding amount of all Revolving
Credit Loans made by such Bank, plus interest accrued thereon, as set forth
below. The Borrower irrevocably authorizes each Bank to make or cause to be
made, at or about the time of the Drawdown Date of any Revolving Credit Loan or
at the time of receipt of any payment of principal on such Bank's Revolving
Credit Note, an appropriate notation on such Bank's Revolving Credit Note Record
reflecting the making of such Revolving Credit Loan or (as the case may be) the
receipt of such payment. The outstanding amount of the Revolving Credit Loans
set forth on such Bank's Revolving Credit Note Record shall be prima facie
evidence of the principal amount thereof owing and unpaid to such Bank, but the
failure to record, or any error in so recording, any such amount on such Bank's


<PAGE>   35
                                      -28-



Revolving Credit Note Record shall not limit or otherwise affect the obligations
of the Borrower hereunder or under any Revolving Credit Note to make payments of
principal of or interest on any Revolving Credit Note when due.

        2.5. INTEREST ON REVOLVING CREDIT LOANS. Except as otherwise provided in
Section 9.10,

                (a) each Revolving Credit Loan that is a Base Rate Loan shall
        bear interest for the period commencing with the Drawdown Date thereof
        and ending on the last day of the Interest Period with respect thereto
        at a rate per annum equal to the sum of (i) the Base Rate in effect from
        time to time plus (ii) the Applicable Margin then in effect with respect
        to Base Rate Loans; and

               (b) each Revolving Credit Loan that is a Eurodollar Rate Loan
        shall bear interest for the period commencing with the Drawdown Date
        thereof and ending on the last day of the Interest Period with respect
        thereto at a rate per annum equal to the sum of (i) the Eurodollar Rate
        determined for such Interest Period plus (ii) the Applicable Margin then
        in effect with respect to Eurodollar Rate Loans.

The Borrower promises to pay interest on each Revolving Credit Loan in arrears
on each Interest Payment Date with respect thereto.

               2.6.1. IN GENERAL. The Borrower shall deliver to the Agent a Loan
        Request with respect to each Revolving Credit Loan requested hereunder
        no less than (i) one (1) Business Day prior to the proposed Drawdown
        Date of any Base Rate Loan and (ii) three (3) Eurodollar Business Days
        prior to the proposed Drawdown Date of any Eurodollar Rate Loan. Each
        such notice shall specify (A) the principal amount of the Revolving
        Credit Loan requested, (B) the proposed Drawdown Date of such Revolving
        Credit Loan, (C) the Interest Period for such Revolving Credit Loan and
        (D) the Type of such Revolving Credit Loan. Promptly upon receipt of any
        such notice, the Agent shall notify each of the Revolving Credit Banks
        thereof. Each Loan Request shall be irrevocable and binding on the
        Borrower and shall obligate the Borrower to accept the Revolving Credit
        Loan requested from the Banks on the proposed Drawdown Date. Each Loan
        Request shall be in a minimum aggregate amount of $1,000,000 or an
        integral multiple thereof.

               2.6.2. LOANS TO COVER REIMBURSEMENT OBLIGATIONS. Notwithstanding
        the notice and minimum amount requirements set forth in Section 2.6.1,
        the Agent shall, unless otherwise instructed by the Majority Banks and
        subject to the satisfaction of the conditions set forth herein,
        including, without limitation, Section 16 hereof, make Revolving Credit
        Loans to the Borrower on the date that any draft presented under any
        Letter of Credit is honored by the Agent, or any date on which the Agent
        otherwise makes a payment with respect thereto, in an amount sufficient
        to pay in full the obligations of the Borrower under Section 5.2 in
        respect of the honor of such draft or the making of such payment. The
        Borrower hereby requests and authorizes the Agent to make from time to
        time such Revolving Credit Loans by means of appropriate entries in the
        books and records of the Agent and to notify the Revolving Credit Banks
        of the date and amount of any such Revolving Credit Loans. The Borrower
        acknowledges and agrees that the making of such Revolving Credit Loans
        shall, in each case, be subject in all respects to the provisions of
        this Credit Agreement as if they were Revolving Credit Loans covered by
        a Loan Request including the limitations set forth in Section 2.1 and
        the requirement that the applicable provisions of Section 16 be
        satisfied. Absent manifest error on the part of the Agent, all actions
        taken by the Agent pursuant to the provisions of this Section 2.6.2
        shall be conclusive and binding on the Borrower. Revolving Credit Loans
        made pursuant to this Section 2.6.2 shall be Base Rate Loans (subject to
        conversion pursuant to Section 2.7 hereof) and shall bear interest at
        the rate provided for Revolving Credit Loans in Section 2.5 hereof. Each
        of the Banks hereby acknowledges and agrees that a Revolving Credit Loan
        made by the Agent pursuant to this Section 2.6.2 shall (i) be subject in
        all respects to the provisions of this Credit Agreement (including,
        without limitation, Section 2.8 hereof) and (ii) obligate each Bank to
        advance to the Agent the amount of such Bank's Revolving Credit
        Commitment Percentage of such Revolving Credit Loan.

        2.7.  CONVERSION OPTIONS.  

               2.7.1. CONVERSION TO DIFFERENT TYPE OF REVOLVING CREDIT LOAN.
        The Borrower may elect from time to time to convert any outstanding
        Revolving Credit Loan to a Revolving Credit Loan of another Type,
        provided that (i) with respect to any such conversion of a Revolving
        Credit Loan to a Base Rate Loan, the Borrower shall give the Agent at
        least one (1) Business Day prior written notice of such election; (ii)
        with respect to any such conversion of a Base Rate Loan to a Eurodollar
        Rate Loan, the Borrower shall give the Agent at least three (3)
        Eurodollar Business Days prior written notice of such election; (iii)
        with respect to any such conversion of 

<PAGE>   37
                                      -30-


        a Eurodollar Rate Loan into a Base Rate Loan, such conversion shall only
        be made on the last day of the Interest Period with respect thereto; and
        (iv) no Loan may be converted into a Eurodollar Rate Loan when any
        Default or Event of Default has occurred and is continuing. On the date
        on which such conversion is being made, each Bank shall take such action
        as is necessary to transfer its Revolving Credit Commitment Percentage
        of such Revolving Credit Loans to its Domestic Lending Office or its
        Eurodollar Lending Office, as the case may be. All or any part of
        outstanding Revolving Credit Loans of any Type may be converted into a
        Revolving Credit Loan of another Type as provided herein, provided that
        any partial conversion shall be in an aggregate principal amount of
        $1,000,000 or a whole multiple thereof. Each Conversion Request relating
        to the conversion of a Revolving Credit Loan to a Eurodollar Rate Loan
        shall be irrevocable by the Borrower.

               2.7.2. CONTINUATION OF TYPE OF REVOLVING CREDIT LOAN. Any
        Revolving Credit Loan of any Type may be continued as a Revolving Credit
        Loan of the same Type upon the expiration of an Interest Period with
        respect thereto by compliance by the Borrower with the notice provisions
        contained in Section 2.7.1; provided that no Eurodollar Rate Loan may be
        continued as such when any Default or Event of Default has occurred and
        is continuing, but shall be automatically converted to a Base Rate Loan
        on the last day of the first Interest Period relating thereto ending
        during the continuance of any Default or Event of Default of which
        officers of the Agent active upon the Borrower's account have actual
        knowledge. In the event that the Borrower fails to provide any such
        notice with respect to the continuation of any Eurodollar Rate Loan as
        such, then such Eurodollar Rate Loan shall be automatically converted to
        a Base Rate Loan on the last day of the first Interest Period relating
        thereto. The Agent shall notify the Revolving Credit Banks promptly when
        any such automatic conversion contemplated by this Section 2.7 is
        scheduled to occur.

               2.7.3. EURODOLLAR RATE LOANS. Any conversion to or from
        Eurodollar Rate Loans shall be in such amounts and be made pursuant to
        such elections so that, after giving effect thereto, the aggregate
        principal amount of all Eurodollar Rate Loans having the same Interest
        Period shall not be less than $1,000,000 or a whole multiple thereof. At
        no time with respect to all Loans under this Credit Agreement shall
        there be more than five (5) Eurodollar Rate Loans having different
        interest periods outstanding.

        2.8.  FUNDS FOR REVOLVING CREDIT LOANS.  

<PAGE>   38
                                      -31-



               2.8.1. FUNDING PROCEDURES. Not later than 1:00 p.m. (Boston
        time) on the proposed Drawdown Date of any Revolving Credit Loans, each
        of the Banks will make available to the Agent, at the Agent's Head
        Office, in immediately available funds, the amount of such Bank's
        Revolving Credit Commitment Percentage of the amount of the requested
        Revolving Credit Loans. Upon receipt from one or more Banks of such
        amounts, and upon receipt of the documents required by Sections 15 and
        16 and the satisfaction of the other conditions set forth therein, to
        the extent applicable, the Agent will make available to the Borrower the
        aggregate amount of such Revolving Credit Loans made available to the
        Agent by the Banks. The failure or refusal of any Bank to make available
        to the Agent at the aforesaid time and place on any Drawdown Date the
        amount of its Revolving Credit Commitment Percentage of the requested
        Revolving Credit Loans shall not relieve any other Bank from its several
        obligation hereunder to make available to the Agent the amount of such
        other Bank's Revolving Credit Commitment Percentage of any requested
        Revolving Credit Loans.

               2.8.2. ADVANCES BY AGENT. The Agent may, unless notified to the
        contrary by any Bank prior to a Drawdown Date, assume that such Bank has
        made available to the Agent on such Drawdown Date the amount of such
        Bank's Revolving Credit Commitment Percentage of the Revolving Credit
        Loans to be made on such Drawdown Date, and the Agent may (but it shall
        not be required to), in reliance upon such assumption, make available to
        the Borrower a corresponding amount. If any Bank makes available to the
        Agent such amount on a date after such Drawdown Date, such Bank shall
        pay to the Agent on demand an amount equal to the product of (i) the
        average computed for the period referred to in clause (iii) below, of
        the weighted average interest rate paid by the Agent for federal funds
        acquired by the Agent during each day included in such period, times
        (ii) the amount of such Bank's Revolving Credit Commitment Percentage of
        such Revolving Credit Loans, times (iii) a fraction, the numerator of
        which is the number of days that elapse from and including such Drawdown
        Date to the date on which the amount of such Bank's Revolving Credit
        Commitment Percentage of such Revolving Credit Loans shall become
        immediately available to the Agent, and the denominator of which is 365.
        A statement of the Agent submitted to such Bank with respect to any
        amounts owing under this paragraph shall be prima facie evidence of the
        amount due and owing to the Agent by such Bank. If the amount of such
        Bank's Revolving Credit Commitment Percentage of such Revolving Credit
        Loans is not made available to the Agent by such Bank within three (3)
        Business Days following such Drawdown Date, the 



<PAGE>   39
                                      -32-




        Agent shall be entitled to recover such amount from the Borrower on
        demand, with interest thereon at the rate per annum applicable to the
        Revolving Credit Loans made on such Drawdown Date.

        2.9.  THE SWING LINE.  

               2.9.1. ADVANCES BY AGENT. Subject to the terms and conditions
        hereinafter set forth, upon notice by the Borrower made to the Agent in
        accordance with Section 2.9.2 hereof, BKB in its capacity as Swing Line
        Bank (the "Swing Line Bank") agrees to lend to the Borrower Swing Line
        Loans on any Business Day from the Closing Date until the Maturity Date
        in an aggregate principal amount not to exceed $5,000,000 (the "Maximum
        Swing Line Loan Amount"). Each Swing Line Loan shall be in a minimum
        amount equal to $10,000 or integral multiple thereof. Notwithstanding
        any other provisions of this Agreement and in addition to the limit set
        forth above, at no time shall the aggregate principal amount of all
        outstanding Swing Line Loans exceed the Total Revolving Credit
        Commitment then in effect minus the sum of (i) the aggregate principal
        amount of all Revolving Credit Loans outstanding, and (ii) the Maximum
        Drawing Amount and all Unpaid Reimbursement Obligations; provided
        however that subject to the limitations set forth in this Section 2.9
        from time to time the sum of the aggregate outstanding Swing Line Loans
        plus all outstanding Revolving Credit Loans made by BKB plus the Maximum
        Drawing Amount of all Letters of Credit and all Unpaid Reimbursement
        Obligations may exceed BKB's Revolving Credit Commitment Percentage of
        the Total Revolving Credit Commitment then in effect.

               2.9.2. NOTICE OF BORROWING. When the Borrower desires the Swing
        Line Bank to make a Swing Line Loan, it shall send to the Agent a Loan
        Request, which shall set forth the principal amount of the proposed
        Swing Line Loan and the Swing Line Loan Maturity Date relating thereto,
        which shall in no event be later than the earlier of (i) the tenth
        (10th) day following the Drawdown Date of such Swing Line Loan and (ii)
        the Maturity Date. Each such Loan Request must be received by the Agent
        not later than 2:00 p.m. (Boston time) on the date of the proposed
        borrowing. Each Loan Request shall be irrevocable and binding on the
        Borrower and shall obligate the Borrower to borrow the Swing Line Loan
        from the Swing Line Bank on the proposed Drawdown Date thereof. Upon
        satisfaction of the applicable conditions set forth in this Agreement,
        on the proposed Drawdown Date the Swing Line Bank shall make the
        proposed Swing Line Loan available to the Borrower no later 


<PAGE>   40
                                      -33-



        than 3:00 p.m. (Boston time) on the proposed Drawdown Date by crediting
        the amount of the Swing Line Loan to the Borrower's account maintained
        with the Agent at the Head Office; provided that the Swing Line Bank
        shall not advance any Swing Line Loans after it has received notice from
        any Bank that a Default or Event of Default has occurred and stating
        that no new Swing Line Loans are to be made until such Default or Event
        of Default has been cured or waived in accordance with the provisions of
        this Agreement. The Swing Line Bank shall not be obligated to make any
        Swing Line Loans at any time when any Bank is a Delinquent Bank unless
        the Swing Line Bank has entered into arrangements satisfactory to it to
        eliminate the Swing Line Bank's risk with respect to such Delinquent
        Bank, including by cash collateralizing such Delinquent Bank's Revolving
        Credit Commitment Percentage of the outstanding Swing Line Loans and any
        additional Swing Line Loans to be made.

               2.9.3. INTEREST ON SWING LINE LOANS. Each Swing Line Loan shall
        be a Base Rate Loan and, except as otherwise provided in Section 9.10
        hereof, shall bear interest from the Drawdown Date thereof until repaid
        in full at a rate per annum equal to the sum of the Base Rate in effect
        from time to time plus the Applicable Margin then in effect with respect
        to Base Rate Loans. The Borrower promises to pay interest on each Swing
        Line Loan quarterly in arrears on the last day of each calendar quarter.

               2.9.4. REPAYMENT OF SWING LINE LOANS. The Borrower shall repay
        each outstanding Swing Line Loan on or prior to the Swing Line Loan
        Maturity Date relating thereto. Upon notice by the Agent on any Business
        Day (whether before or on the Maturity Date), each of the Banks hereby
        agrees to make payments to the Agent for the account of the Swing Line
        Bank, on the next succeeding Business Day following such notice, in an
        amount equal to such Bank's Revolving Credit Commitment Percentage of
        the aggregate amount of all Swing Line Loans outstanding. The parties
        hereto agree that such payments made to the Agent for the account of the
        Swing Line Bank shall constitute Revolving Credit Loans made to the
        Borrower hereunder, and shall be Base Rate Loans. The proceeds thereof
        shall be applied directly by the Swing Line Bank to such outstanding
        Swing Line Loans. Each Bank hereby absolutely, unconditionally and
        irrevocably agrees to make such Revolving Credit Loans upon one Business
        Day's notice as set forth above, notwithstanding (i) that the amount of
        such Revolving Credit 


<PAGE>   41
                                      -34-



        Loan may not comply with the applicable minimums set forth in Section
        2.6.1 hereof, (ii) the failure of the Borrower to meet the conditions
        set forth in Sections 15 or 16 hereof, (iii) the occurrence or
        continuance of a Default or an Event of Default hereunder, (iv) that the
        date of such Loan may fall after the Maturity Date, and (v) the amount
        of the Total Revolving Credit Commitment in effect at such time. In the
        event that it is impracticable for such amounts to be paid to the Agent
        or for the Swing Line Bank or such Revolving Credit Loans to be made for
        any reason on the date otherwise required above, then each Bank hereby
        agrees that it shall forthwith purchase (as of the date such payment and
        such Revolving Credit Loan would have been made, but adjusted for any
        payments received from the Borrower on or after such date and prior to
        such purchase) from the Swing Line Bank, and the Swing Line Bank shall
        sell to each Bank, such participations in the Swing Line Loans
        (including all accrued and unpaid interest thereon) outstanding as shall
        be necessary to cause the Banks to share in such Swing Line Loans pro
        rata based on their respective Revolving Credit Commitment Percentages
        (without regard to any termination of the Total Revolving Credit
        Commitment) by making available to the Agent for the account of the
        Swing Line Bank an amount equal to such Bank's participation in the
        Swing Line Loans; provided that (x) all interest payable on the Swing
        Line Loans shall be for the account of the Swing Line Bank as a funding
        and administrative fee until the date as of which the respective
        participation is purchased (unless paid to the Swing Line Bank pursuant
        to clause (y) below), and (y) at the time any purchase of such
        participation is actually made, the purchasing Bank shall be required to
        pay the Swing Line Bank interest on the principal amount of the
        participation so purchased for each day from and including the date such
        Revolving Credit Loan would otherwise have been made until the date of
        payment for such participation at the rate per annum equal to the sum of
        the Base Rate plus the Applicable Margin in effect with respect to Base
        Rate Loans during such period.

               2.9.5. THE SWING LINE NOTE. The obligation of the Borrower to
        repay the Swing Line Loans made pursuant to this Agreement and to pay
        interest thereon as set forth in this Agreement shall be evidenced by a
        promissory note of the Borrower with appropriate insertions
        substantially in the form of Exhibit A-2 attached hereto (the "Swing
        Line Note"), dated the Closing Date and payable to the order of the
        Swing Line Bank in a principal amount stated to be the lesser of (i) the
        Maximum Swing Line Loan Amount, or (ii) the aggregate principal amount



<PAGE>   42
                                      -35-



        of Swing Line Loans at any time advanced by the Swing Line Bank and
        outstanding hereunder. The Borrower irrevocably authorizes the Swing
        Line Bank to make or cause to be made, at or about the time of the
        Drawdown Date of any Swing Line Loan or at the time of receipt of any
        payment of principal on the Swing Line Note, an appropriate notation on
        the Swing Line Note Record reflecting the making of such Swing Line Loan
        or (as the case may be) the receipt of such payment. The outstanding
        amount of the Swing Line Loans set forth on the Swing Line Note Record
        shall be prima facie evidence of the principal amount thereof owing and
        unpaid to the Swing Line Bank, but the failure to record, or any error
        in so recording, any such amount on such Record shall not limit or
        otherwise affect the actual amount of the obligations of the Borrower
        hereunder or under the Swing Line Note to make payments of principal of
        or interest on the Swing Line Note when due. 

                  3. REPAYMENT OF THE REVOLVING CREDIT LOANS.

        3.1. MATURITY. The Borrower promises to pay on the Maturity Date, and
there shall become absolutely due and payable on the Maturity Date, all of the
Revolving Credit Loans outstanding on such date, together with any and all
accrued and unpaid interest thereon.

        3.2. MANDATORY REPAYMENTS OF REVOLVING CREDIT LOANS. If at any time the
sum of the outstanding principal amount of the Revolving Credit Loans, the
outstanding principal amount of the Swing Line Loans, the Maximum Drawing Amount
and all Unpaid Reimbursement Obligations exceeds the Total Revolving Credit
Commitment, then the Borrower shall immediately pay the amount of such excess to
the Agent for the respective accounts of the Banks for application: first, to
any Unpaid Reimbursement Obligations; second, to the Swing Line Loans; third, to
the Revolving Credit Loans; and fourth, to provide to the Agent cash collateral
for Reimbursement Obligations as contemplated by Section 5.2(b) and (c). In
addition, the Borrower shall prepay the Revolving Credit Loans as and when
required by Section 8, and the Total Revolving Credit Commitment shall be
reduced accordingly. Each payment of any Unpaid Reimbursement Obligations or
prepayment of Revolving Credit Loans shall be allocated among the Banks, in
proportion, as nearly as practicable, to each Reimbursement Obligation or (as
the case may be) the respective unpaid principal amount of each Bank's Revolving
Credit Note, with adjustments to the extent practicable to equalize any prior
payments or repayments not exactly in proportion.

        3.3. OPTIONAL REPAYMENTS OF REVOLVING CREDIT LOANS. The Borrower shall
have the right, at its election, to repay the outstanding amount of the
Revolving Credit Loans, as a whole or in part, at any time 


<PAGE>   43
                                      -36-



without penalty or premium, provided that all prepayments of Eurodollar Rate
Loans prior to the end of the Interest Period relating thereto shall obligate
the Borrower to pay any breakage costs associated with such Eurodollar Rate
Loans in accordance with Section 9.9 hereof. The Borrower shall give the Agent,
no later than 1:00 p.m., Boston time, at least one (1) Business Day prior
written notice of any proposed prepayment pursuant to this Section 3.3 of Base
Rate Loans, and three (3) Eurodollar Business Days notice of any proposed
prepayment pursuant to this Section 3.3 of Eurodollar Rate Loans, in each case
specifying the proposed date of prepayment of Revolving Credit Loans and the
principal amount to be prepaid. Each such partial prepayment of the Revolving
Credit Loans shall be in an integral multiple of $1,000,000, shall be
accompanied by the payment of accrued interest on the principal prepaid to the
date of prepayment and shall be applied, in the absence of instruction by the
Borrower, first to the principal of Base Rate Loans and then to the principal of
Eurodollar Rate Loans. Each partial prepayment shall be allocated among the
Banks, in proportion, as nearly as practicable, to the respective unpaid
principal amount of each Bank's Revolving Credit Note, with adjustments to the
extent practicable to equalize any prior repayments not exactly in proportion.

                               4. THE TERM LOAN.

        4.1. COMMITMENT TO LEND. Subject to the terms and conditions set forth
in this Credit Agreement, each Bank severally agrees to lend to the Borrower on
the Closing Date the amount of its Term Percentage of the principal amount of
$25,000,000 (the "Aggregate Term Loan Amount"); provided however that at the
request of the Borrower made no later than three (3) Business Days prior to the
Closing Date each Bank severally agrees to lend to the Borrower on the Closing
Date its Term Percentage of such lesser amount in an integral multiple of
$1,000,000 (but not less than $22,000,000) as the Borrower may request (the
"Initial Term Loan Amount"). In the event the portion of the Term Loan advanced
on the Closing Date is less than the Aggregate Term Loan Amount and subject to
the terms and conditions set forth in this Credit Agreement, each Bank severally
agrees to lend to the Borrower, upon not less than three (3) Business Days
notice to the Agent, on a single date (the "Second Term Loan Disbursement Date")
occurring no later than sixty (60) days after the Closing Date the amount of its
Term Percentage of such amount (in an integral multiple of $1,000,000) as may be
requested by the Borrower not to exceed the Aggregate Term Loan Amount less the
Initial Term Loan Amount; provided that in no event shall the sum of (i) the
portion of the Term Loan advanced on the Closing Date and (ii) the portion of
the Term Loan advanced on the Second Term Loan Disbursement Date exceed the
Aggregate Term Loan Amount. In the event the Borrower fails for any reason to
borrow such portion prior to 

<PAGE>   44
                                      -37-



sixty (60) days after the Closing Date, or if the Borrower fails to satisfy any
conditions set forth in Section 16 on the proposed Second Term Loan Disbursement
Date, then no further portion of the Term Loan shall be advanced by the Banks
hereunder. Each request for a portion of the Term Loan hereunder shall be made
by delivering a Loan Request to the Agent setting forth the requested amount of
such portion and shall constitute a representation and warranty by the Borrower
that the conditions set forth in Section 15 and Section 16, in the case of the
initial portion of the Term Loan to be made on the Closing Date, and Section 16,
in the case of the portion of the Term Loan to be made on the Second Term Loan
Disbursement Date, have been satisfied on the date of such request.

        4.2. THE TERM NOTES. The Term Loan shall be evidenced by separate
promissory notes of the Borrower in substantially the form of Exhibit A-3 hereto
(each a "Term Note"), dated the Closing Date and completed with appropriate
insertions. One Term Note shall be payable to the order of each Bank in a
principal amount equal to such Bank's Term Percentage of the Term Loan and
representing the obligation of the Borrower to pay to such Bank such principal
amount or, if less, such Bank's Term Percentage of the outstanding amount of the
Term Loan, plus interest accrued thereon, as set forth below. The Borrower
irrevocably authorizes each Bank to make or cause to be made a notation on such
Bank's Term Note Record reflecting the original principal amount of such Bank's
Term Percentage of the Term Loan and, at or about the time of such Bank's
receipt of any principal payment on such Bank's Term Note, an appropriate
notation on such Bank's Term Note Record reflecting such payment. The aggregate
unpaid amount set forth on such Bank's Term Note Record shall be prima facie
evidence of the principal amount thereof owing and unpaid to such Bank, but the
failure to record, or any error in so recording, any such amount on such Bank's
Term Note Record shall not affect the obligations of the Borrower hereunder or
under any Term Note to make payments of principal of and interest on any Term
Note when due.

        4.3. SCHEDULE OF INSTALLMENT PAYMENTS OF PRINCIPAL OF TERM LOAN;
MANDATORY PREPAYMENTS.

        (a) The Borrower promises to pay to the Agent for the account of the
Banks the principal amount of the Term Loan on such dates and in such amounts as
set forth in the table below, with a final payment on the Maturity Date in an
amount equal to the unpaid balance of the Term Loan.

</TABLE>

        (b) The Borrower shall prepay the Term Loan as and when required by
Section 8.

        (c) In the event the portion (if any) of Term Loan to be advanced on the
Second Term Loan Disbursement Date is not made for any reason, the scheduled
installments of principal due on the Term Loan as set forth in clause (a) above
shall be reduced in the inverse order of maturity by the amount by which the
Aggregate Term Loan Amount exceeds the Initial Term Loan Amount.

        4.4. OPTIONAL PREPAYMENT OF TERM LOAN. The Borrower shall have the right
at any time to prepay the Term Loan on or before the Maturity Date, as a whole,
or in part, upon not less than five (5) Business Days prior written notice to
the Agent, without premium or penalty, provided that (i) each partial prepayment
shall be in the principal amount of $1,000,000 or an integral multiple thereof,
(ii) no portion of the Term Loan bearing interest at the Eurodollar Rate may be
prepaid pursuant to this Section 4.4 except on the last day of the Interest
Period relating thereto unless the Borrower pays any breakage costs associated
therewith in accordance with Section 9.9; and (iii) each partial prepayment
shall 


<PAGE>   46
                                      -39-



be allocated among the Banks in proportion, as nearly as practicable, to
the respective outstanding amount of each Bank's Term Note, with adjustments to
the extent practicable to equalize any prior prepayments not exactly in
proportion. Any prepayment of principal of the Term Loan shall include all
interest accrued to the date of prepayment and shall be applied against the
scheduled installments of principal due on the Term Loan in the inverse order of
maturity. No amount repaid with respect to the Term Loan may be reborrowed.

        4.5.  INTEREST ON TERM LOANS.  

               4.5.1. INTEREST RATES. Except as otherwise provided in Section
        9.10, the Term Loan shall bear interest during each Interest Period
        relating to all or any portion of the Term Loan at the following rates:

                             (i) to the extent that all or any portion of the
                      Term Loan bears interest during such Interest Period at
                      the Base Rate, the Term Loan or such portion shall bear
                      interest during such Interest Period at the rate per annum
                      equal to the Base Rate in effect from time to time plus
                      the Applicable Margin then in effect with respect to Base
                      Rate Loans; and

                      (ii) to the extent that all or any portion of the Term
                      Loan bears interest during such Interest Period at the
                      Eurodollar Rate, the Term Loan or such portion shall bear
                      interest during such Interest Period at the rate per annum
                      equal to the Eurodollar rate plus the Applicable Margin
                      then in effect with respect to Eurodollar Rate Loans.

               4.5.2. PAYMENT OF INTEREST. The Borrower promises to pay interest
        on the Term Loans or any portion thereof outstanding during each
        Interest Period in arrears on each Interest Payment Date applicable to
        such Interest Period.

               4.5.3. NOTIFICATION BY BORROWER. The Borrower shall notify the
        Agent, such notice to be irrevocable, at least three (3) Eurodollar
        Business Days prior to the Closing Date and the Second term Loan
        Disbursement Date of the Term Loan if all or any portion of the Term
        Loan to be borrowed on such date is to bear interest at the Eurodollar
        Rate. After the Term Loan has been made, the provisions of Section 2.7
        shall apply mutatis mutandis with respect to all or any 


<PAGE>   47
                                      -40-


        portion of the Term Loan so that the Borrower may have the same interest
        rate options with respect to all or any portion of the Term Loan as it
        would be entitled to with respect to the Revolving Credit Loans, subject
        to the same limitations as apply to Revolving Credit Loans.

               4.5.4. AMOUNTS, ETC. Any portion of the Term Loan bearing
        interest at the Eurodollar Rate relating to any Interest Period shall be
        in the amount of $1,000,000 or an integral multiple thereof. No Interest
        Period relating to the Term Loan or any portion thereof bearing interest
        at the Eurodollar Rate shall extend beyond the date on which a regularly
        scheduled installment payment of the principal of the Term Loan is to be
        made unless a portion of the Term Loan at least equal to such
        installment payment has an Interest Period ending on such date or is
        then bearing interest at the Base Rate.

                              5. LETTERS OF CREDIT.

        5.1.  LETTER OF CREDIT COMMITMENTS.

               5.1.1. COMMITMENT TO ISSUE LETTERS OF CREDIT. Subject to the
        terms and conditions hereof and the execution and delivery by the
        Borrower of a letter of credit application on the Agent's customary form
        (a "Letter of Credit Application"), the Agent on behalf of the Banks and
        in reliance upon the agreement of the Banks set forth in Section 5.1.4
        and upon the representations and warranties of the Borrower contained
        herein, agrees, in its individual capacity, to issue, extend and renew
        Letters of Credit for the account of the Borrower in such form as may be
        requested from time to time by the Borrower and agreed to by the Agent;
        provided, however, that, after giving effect to such request, at no time
        shall (a) the sum of the aggregate Maximum Drawing Amount and all Unpaid
        Reimbursement Obligations exceed the Letter of Credit Limit in effect at
        such time, and (b) the sum of (i) the Maximum Drawing Amount on all
        Letters of Credit, (ii) all Unpaid Reimbursement Obligations, (iii) the
        amount of all Swing Line Loans outstanding, and (iv) the amount of all
        Revolving Credit Loans outstanding exceed the Total Revolving Credit
        Commitment. The parties hereto hereby acknowledge and agree that the IRB
        Letter of Credit shall on the Closing Date be deemed to be, and shall
        become, a Letter of Credit outstanding hereunder for the account of the
        Borrower, and shall be subject to all of the provisions of this Credit
        Agreement relating to Letters of Credit issued hereunder. Each of the
        Banks acknowledges that it has made arrangements with the other Banks
        satisfactory to it with respect to its pro rata share of any portion of
        Letter of Credit Fees relating to periods after the Closing Date paid
        prior to the Closing Date by the Borrower in respect of the IRB Letter
        of Credit.

                                      -41-



               5.1.2. LETTER OF CREDIT APPLICATIONS. Each Letter of Credit
        Application shall be completed to the satisfaction of the Agent. In the
        event that any provision of any Letter of Credit Application shall be
        inconsistent with any provision of this Credit Agreement, then the
        provisions of this Credit Agreement shall, to the extent of any such
        inconsistency, govern.

               5.1.3. TERMS OF LETTERS OF CREDIT. Each Letter of Credit issued,
        extended or renewed hereunder shall, among other things, (i) provide for
        the payment of sight drafts for honor thereunder when presented in
        accordance with the terms thereof and when accompanied by the documents
        described therein, and (ii) have an expiry date no later than the
        earlier of (a) one year after the date of issuance of such Letter of
        Credit and (b) the date which is fourteen (14) days (or, if the Letter
        of Credit is confirmed by a confirmer or otherwise provides for one or
        more nominated persons, forty-five (45) days) prior to the Maturity
        Date. Each Letter of Credit so issued, extended or renewed shall be
        subject to either the Uniform Customs or the International Standby
        Practices.

               5.1.4. REIMBURSEMENT OBLIGATIONS OF BANKS. Each Bank severally
        agrees that it shall be absolutely liable, without regard to the
        occurrence of any Default or Event of Default or any other condition
        precedent whatsoever, to the extent of such Bank's Revolving Credit
        Commitment Percentage, to reimburse the Agent on demand for the amount
        of each draft paid by the Agent under each Letter of Credit to the
        extent that such amount is not reimbursed by the Borrower pursuant to
        Section 5.2 (such agreement for a Bank being called herein the "Letter
        of Credit Participation" of such Bank).

               5.1.5. PARTICIPATIONS OF BANKS. Each such payment made by a Bank
        shall be treated as the purchase by such Bank of a participating
        interest in the Borrower's Reimbursement Obligation under Section 5.2 in
        an amount equal to such payment. Each Bank shall share in accordance
        with its participating interest in any interest which accrues pursuant
        to Section 5.2.

               5.1.6. REDUCTION OF LETTER OF CREDIT LIMIT. Upon any reduction in
        the stated amount of the IRB Letter of Credit (or any replacement Letter
        of Credit issued by the Agent for the account of the Borrower in respect
        of its obligations under the Bond Documents) in accordance with the
        terms thereof, the Letter of Credit Limit shall be reduced automatically
        on the date of such reduction in stated amount by an amount equal to the
        amount of such reduction. In the event the IRB Letter of Credit (or such


<PAGE>   49
                                      -42-


        replacement Letter of Credit) shall terminate or expire the Letter of
        Credit Limit shall be reduced automatically on the date of such
        termination or expiration by an amount equal to the face amount thereof
        as in effect immediately prior to such termination or expiration. No
        reduction of the Letter of Credit Limit hereunder may be reinstated.

        5.2. REIMBURSEMENT OBLIGATION OF THE BORROWER. In order to induce the
Agent to issue, extend and renew each Letter of Credit and the Banks to
participate therein, the Borrower hereby agrees to reimburse or pay to the
Agent, for the account of the Agent or (as the case may be) the Banks, with
respect to each Letter of Credit issued, extended or renewed by the Agent
hereunder,

               (a) except as otherwise expressly provided in Section 5.2(b) and
        (c), on each date that any draft presented under such Letter of Credit
        is honored by the Agent, or the Agent otherwise makes a payment with
        respect thereto, (i) the amount paid by the Agent under or with respect
        to such Letter of Credit, and (ii) the amount of any taxes, fees,
        charges or other costs and expenses whatsoever incurred by the Agent or
        any Bank in connection with any payment made by the Agent or such Bank
        under, or with respect to, such Letter of Credit (it being understood
        that such payment to the Agent may, subject to the satisfaction of the
        conditions set forth herein, be made from the proceeds of a Revolving
        Credit Loan made to the Borrower pursuant to Section 2.6.2),

               (b) upon the reduction (but not termination) of the Total
        Revolving Credit Commitment to an amount less than the Maximum Drawing
        Amount, an amount equal to such difference, which amount shall be held
        by the Agent for the benefit of the Banks and the Agent as cash
        collateral for all Reimbursement Obligations, and

               (c) upon the termination of the Total Revolving Credit
        Commitment, or the acceleration of the Reimbursement Obligations with
        respect to all Letters of Credit in accordance with Section 17, an
        amount equal to the then Maximum Drawing Amount on all Letters of
        Credit, which amount shall be held by the Agent for the benefit of the
        Banks and the Agent as cash collateral for all Reimbursement
        Obligations.

Each such payment shall be made to the Agent at the Agent's Head Office in
immediately available funds or (in the case of clause (a) of this Section 5.2)
from the direct application of the proceeds of a Revolving Credit Loan made
pursuant to Section 2.6.2 hereof. In the event that the obligations of 


<PAGE>   50
                                      -43-



the Borrower under Section 5.2(a) can not, in compliance with the provisions of
this Credit Agreement, be satisfied in full by the making of a Revolving Credit
Loan pursuant to Section 2.6.2, the Agent shall so notify the Borrower, in which
case the obligations of the Borrower under Section 5.2(a) shall be immediately
due and payable to the Agent. Interest on any and all amounts remaining unpaid
by the Borrower under this Section 5.2 at any time from the date such amounts
become due and payable (whether as stated in this Section 5.2, by acceleration
or otherwise) until payment in full (whether before or after judgment) shall be
payable to the Agent on demand at the rate specified in Section 9.10 for overdue
principal on the Revolving Credit Loans.

        5.3. LETTER OF CREDIT PAYMENTS. If any draft shall be presented or other
demand for payment shall be made under any Letter of Credit, the Agent shall
notify the Borrower of the date and amount of the draft presented or demand for
payment and of the date and time when it expects to pay such draft or honor such
demand for payment. If the Borrower fails to reimburse the Agent as provided in
Section 5.2 on or before the date that such draft is paid or other payment is
made by the Agent, the Agent may at any time thereafter notify the Banks of the
amount of any such Unpaid Reimbursement Obligation. No later than 3:00 p.m.
(Boston time) on the Business Day next following the receipt of such notice,
each Bank shall make available to the Agent, at the Agent's Head Office, in
immediately available funds, such Bank's Revolving Credit Commitment Percentage
of such Unpaid Reimbursement Obligation, together with an amount equal to the
product of (i) the average, computed for the period referred to in clause (iii)
below, of the weighted average interest rate paid by the Agent for federal funds
acquired by the Agent during each day included in such period, times (ii) the
amount equal to such Bank's Revolving Credit Commitment Percentage of such
Unpaid Reimbursement Obligation, times (iii) a fraction, the numerator of which
is the number of days that shall have elapsed from and including the date the
Agent paid the draft presented for honor or otherwise made payment to the date
on which such Bank's Revolving Credit Commitment Percentage of such Unpaid
Reimbursement Obligation shall become immediately available to the Agent, and
the denominator of which is 360. The responsibility of the Agent to the Borrower
and the Banks shall be only to determine that the documents (including each
draft) delivered under each Letter of Credit in connection with such presentment
shall be in conformity in all material respects with such Letter of Credit.

        5.4. OBLIGATIONS ABSOLUTE. The Borrower's obligations under this Section
5 shall be absolute and unconditional under any and all circumstances and
irrespective of the occurrence of any Default or Event of Default or any
condition precedent whatsoever or any setoff, counterclaim or 

<PAGE>   51
                                      -44-



defense to payment which the Borrower may have or have had against the Agent,
any Bank or any beneficiary of a Letter of Credit. The Borrower further agrees
with the Agent and the Banks that the Agent and the Banks shall not be
responsible for, and the Borrower's Reimbursement Obligations under Section 5.2
shall not be affected by, among other things, the validity or genuineness of
documents or of any endorsements thereon, even if such documents should in fact
prove to be in any or all respects invalid, fraudulent or forged, or any dispute
between or among the Borrower, the beneficiary of any Letter of Credit or any
financing institution or other party to which any Letter of Credit may be
transferred or any claims or defenses whatsoever of the Borrower against the
beneficiary of any Letter of Credit or any such transferee. The Agent and the
Banks shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit. The Borrower agrees that
any action taken or omitted by the Agent or any Bank under or in connection with
each Letter of Credit and the related drafts and documents, if done in good
faith, shall be binding upon the Borrower and shall not result in any liability
on the part of the Agent or any Bank to the Borrower.

        5.5. RELIANCE BY ISSUER. To the extent not inconsistent with Section
5.4, the Agent shall be entitled to rely, and shall be fully protected in
relying upon, any Letter of Credit or any draft, writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or
teletype message, statement, order or other document delivered in connection
with any Letter of Credit believed by it to be genuine and correct and to have
been signed, sent or made by the proper Person or Persons and upon advice and
statements of legal counsel, independent accountants and other experts selected
by the Agent. The Agent shall be fully justified in failing or refusing to take
any action under this Agreement unless it shall first have received such advice
or concurrence of the Majority Banks as it reasonably deems appropriate or it
shall first be indemnified to its reasonable satisfaction by the Banks against
any and all liability and expense which may be incurred by it by reason of
taking or continuing to take any such action. The Agent shall in all cases be
fully protected in acting, or in refraining from acting, under this Agreement in
accordance with a request of the Majority Banks, and such request and any action
taken or failure to act pursuant thereto shall be binding upon the Banks and all
future holders of the Revolving Credit Notes or of Letter of Credit
Participations.

        5.6. LETTER OF CREDIT FEES. The Borrower shall, on the date of issuance
or any extension or renewal of any Letter of Credit, pay fees (each a "Letter of
Credit Fee") semiannually in advance, to the Agent in respect of each Letter of
Credit consisting of (i) the Applicable Margin per 

<PAGE>   52
                                      -45-



annum then in effect with respect to Eurodollar Rate Loans at the time of
determination multiplied by the face amount of such standby Letter of Credit,
which such fee shall be for the account of the Banks in accordance with their
respective Revolving Credit Commitment Percentages and (ii) a fronting fee equal
to 0.125% per annum of the face amount of such standby Letter of Credit, which
such fee shall be for the account of the Agent. The Borrower shall also pay to
the Agent, for the Agent's own account, on the date of issuance or any extension
or any renewal of any Letter of Credit and at such other time or times as such
charges are customarily made by the Agent, the Agent's customary issuance,
amendment, negotiation or document examination fees in respect of each Letter of
Credit. 

                          6. THE ACQUISITION FACILITY.

        6.1. COMMITMENT TO LEND. Subject to the terms and conditions set forth
in this Credit Agreement, each of the Banks severally agrees to lend to the
Borrower from time to time between the Closing Date and the Maturity Date upon
notice by the Borrower to the Agent given in accordance with Section 6.6, such
sums as are requested by the Borrower up to a maximum aggregate amount advanced
(after giving effect to all amounts requested) at any one time equal to such
Bank's Acquisition Loan Commitment, provided that the sum of the amount of the
Acquisition Loans advanced by the Banks to the Borrower (after giving effect to
all amounts requested) shall not exceed the Total Acquisition Loan Commitment.
The Acquisition Loans shall be made pro rata in accordance with each Bank's
Acquisition Loan Commitment Percentage. Each request for a Acquisition Loan
hereunder shall constitute a representation and warranty by the Borrower that
the conditions set forth in Section 15 and Section 16, in the case of the
initial Acquisition Loans to be made on the Closing Date, and Section 16, in the
case of all other Acquisition Loans, have been satisfied on the date of such
request.

        6.2. COMMITMENT FEE. The Borrower agrees to pay to the Agent, for the
accounts of the Banks in accordance with their respective Acquisition Loan
Commitment Percentages, a commitment fee (the "Acquisition Loan Commitment Fee")
at the rate per annum equal to the Commitment Fee Rate then in effect on the
average daily amount during each calendar quarter or portion thereof from the
Closing Date to the Maturity Date by which the Total Acquisition Loan Commitment
exceeds the aggregate outstanding amount of Acquisition Loans. Such Acquisition
Loan Commitment Fee shall be payable quarterly in arrears on the first day of
each calendar quarter for the immediately preceding calendar quarter commencing
on the first such date following the date hereof, with a final payment on the
Maturity Date or any earlier date on which the Acquisition Loan Commitments
shall terminate.

        6.3. REDUCTION OF TOTAL ACQUISITION LOAN COMMITMENT. The Borrower shall
have the right at any time and from time to time upon five (5) Business Days
prior written notice to the Agent to reduce by $1,000,000 or an integral
multiple thereof or terminate entirely the Total Acquisition Loan Commitment,
whereupon the Acquisition Loan Commitments of the Banks shall be reduced pro
rata in accordance with their respective Acquisition Loan Commitment Percentages
of the amount specified in such notice, or, as the case may be, terminated.
Promptly after receiving any notice of the Borrower delivered pursuant to this
Section 6.3, the Agent will notify the Banks of the substance thereof. Upon the
effective date of any such reduction or termination, the Borrower shall pay to
the Agent for the respective accounts of the Banks the full amount of any
Acquisition Loan Commitment Fee then accrued on the amount of the reduction. No
reduction or termination of the Acquisition Loan Commitments may be reinstated.

        6.4. THE ACQUISITION NOTES. The Acquisition Loans shall be evidenced by
separate promissory notes of the Borrower in substantially the form of Exhibit
A-4 hereto (each an "Acquisition Note"), dated as of the Closing Date and
completed with appropriate insertions. One Acquisition Note shall be payable to
the order of each Bank in a principal amount equal to such Bank's Acquisition
Loan Commitment or, if less, the outstanding amount of Acquisition Loans made by
such Bank, plus interest accrued thereon, as set forth below. The Borrower
irrevocably authorizes each Bank to make or cause to be made, at or about the
time of the Drawdown Date of any Acquisition Loan or at the time of receipt of
any payment of principal on such Bank's Acquisition Note, an appropriate
notation on such Bank's Acquisition Note Record reflecting the making of such
Acquisition Loan or (as the case may be) the receipt of such payment. The
outstanding amount of the Acquisition Loans set forth on such Bank's Acquisition
Note Record shall be prima facie evidence of the principal amount thereof owing
and unpaid to such Bank, but the failure to record, or any error in so
recording, any such amount on such Bank's Acquisition Note Record shall not
limit or otherwise affect the obligations of the Borrower hereunder or under any
Acquisition Note to make payments of principal of interest on any Acquisition
Note when due.

        6.5. INTEREST ON ACQUISITION LOANS. Except as otherwise provided in
Section 9.10,

               (a) each Acquisition Loan that is a Base Rate Loan shall bear
        interest for the period commencing with the Drawdown Date thereof and
        ending on the last day of the Interest Period with respect thereto at a
        rate per annum equal to the sum of the Base 


<PAGE>   54
                                      -47-



        Rate in effect from time to time plus the Applicable Margin then in
        effect with respect to Base Rate Loans; and

               (b) each Acquisition Loan that is a Eurodollar Rate Loan shall
        bear interest for the period commencing with the Drawdown Date thereof
        and ending on the last day of the Interest Period with respect thereto
        at a rate per annum equal to the sum of the Eurodollar Rate plus the
        Applicable Margin then in effect with respect to Eurodollar Rate Loans.

The Borrower promises to pay interest on each Acquisition Loan in arrears on
each Interest Payment Date with respect thereto.

        6.6. REQUESTS FOR ACQUISITION LOANS. The Borrower shall give to the
Agent written notice in the form of a Loan Request for each Acquisition Loan
requested hereunder no less than (i) one (1) Business Day prior to the proposed
Drawdown Date of any Base Rate Loan and (ii) three (3) Eurodollar Business Days
prior to the proposed Drawdown Date of any Eurodollar Rate Loan. Each such
notice shall specify (A) the principal amount of the Acquisition Loan requested,
(B) the proposed Drawdown Date of such Acquisition Loan, (C) the Interest Period
for such Acquisition Loan and (D) the Type of such Acquisition Loan. Promptly
upon receipt of any such notice, the Agent shall notify each of the Banks
thereof. Each Loan Request shall be irrevocable and binding on the Borrower and
shall obligate the Borrower to accept the Acquisition Loan requested from the
Banks on the proposed Drawdown Date. Each Loan Request with respect to a
Acquisition Loan shall be in a minimum aggregate amount of $1,000,000 or an
integral multiple thereof. After a Acquisition Loan has been made, the
provisions of Section 2.7 shall apply mutatis mutandis with respect to all or
any portion of the Acquisition Loans so that the Borrower may have the same
interest rate options with respect to the Acquisition Loans as it would be
entitled to with respect to the Revolving Credit Loans, subject to the same
limitations as apply to Revolving Credit Loans.

        6.7.  FUNDS FOR ACQUISITION LOANS.

               6.7.1. FUNDING PROCEDURES. Not later than 11:00 a.m. (Boston
        time) on the proposed Drawdown Date of any Acquisition Loan, each of the
        Banks will make available to the Agent, at the Agent's Head Office, in
        immediately available funds, the amount of such Bank's Acquisition Loan
        Commitment Percentage of the amount of the requested Acquisition Loan.
        Upon receipt from each Bank of such amount, and upon receipt of the
        documents required by Sections 15 and 16 and the satisfaction of the
        other conditions set forth therein, to the extent applicable, the Agent
        will make 


<PAGE>   55
                                      -48-


        available to the Borrower the aggregate amount of such Acquisition Loans
        made available to the Agent by the Banks. The failure or refusal of any
        Bank to make available to the Agent at the aforesaid time and place on
        any Drawdown Date the amount of its Acquisition Loan Commitment
        Percentage of the requested Acquisition Loans shall not relieve any
        other Bank from its several obligation hereunder to make available to
        the Agent the amount of such other Bank's Acquisition Loan Commitment
        Percentage of any requested Acquisition Loans.

               6.7.2. ADVANCES BY AGENT. The Agent may, unless notified to the
        contrary by any Bank prior to a Drawdown Date, assume that such Bank has
        made available to the Agent on such Drawdown Date the amount of such
        Bank's Acquisition Loan Commitment Percentage of the Acquisition Loans
        to be made on such Drawdown Date, and the Agent may (but it shall not be
        required to), in reliance upon such assumption, make available to the
        Borrower a corresponding amount. If any Bank makes available to the
        Agent such amount on a date after such Drawdown Date, such Bank shall
        pay to the Agent on demand an amount equal to the product of (i) the
        average computed for the period referred to in clause (iii) below, of
        the weighted average interest rate paid by the Agent for federal funds
        acquired by the Agent during each day included in such period, times
        (ii) the amount of such Bank's Acquisition Loan Commitment Percentage of
        such Acquisition Loans, times (iii) a fraction, the numerator of which
        is the number of days that elapse from and including such Drawdown Date
        to the date on which the amount of such Bank's Acquisition Loan
        Commitment Percentage of such Acquisition Loans shall become immediately
        available to the Agent, and the denominator of which is 365. A statement
        of the Agent submitted to such Bank with respect to any amounts owing
        under this paragraph shall be prima facie evidence of the amount due and
        owing to the Agent by such Bank. If the amount of such Bank's
        Acquisition Loan Commitment Percentage of such Acquisition Loans is not
        made available to the Agent by such Bank within three (3) Business Days
        following such Drawdown Date, the Agent shall be entitled to recover
        such amount from the Borrower on demand, with interest thereon at the
        rate per annum applicable to the Acquisition Loans made on such Drawdown
        Date. 

                     7. REPAYMENT OF THE ACQUISITION LOANS.

        7.1. MATURITY. The Borrower promises to pay on the Maturity Date, and
there shall become absolutely due and payable on the Maturity Date, all of the
Acquisition Loans outstanding on such date, together with any and all accrued
and unpaid interest thereon.

<PAGE>   56
                                      -49-



        7.2. MANDATORY REPAYMENTS OF ACQUISITION LOANS. If at any time the
outstanding amount of the Acquisition Loans exceeds the Total Acquisition Loan
Commitment, then the Borrower shall immediately pay the amount of such excess to
the Agent for the respective accounts of the Banks for application to the
Acquisition Loans. In addition, the Borrower shall prepay the Acquisition Loans
as and when required by Section 8, and the Total Acquisition Loan Commitment
shall be reduced accordingly. Each prepayment of Acquisition Loans shall be
allocated among the Banks, in proportion, as nearly as practicable, to the
respective unpaid principal amount of each Bank's Acquisition Note, with
adjustments to the extent practicable to equalize any prior payments or
repayments not exactly in proportion.

        7.3. OPTIONAL REPAYMENTS OF ACQUISITION LOANS. The Borrower shall have
the right, at its election, to repay the outstanding amount of the Acquisition
Loans, as a whole or in part, at any time without penalty or premium, provided
that all prepayments of Eurodollar Rate Loans prior to the end of the Interest
Period relating thereto shall obligate the Borrower to pay any breakage costs
associated with such Eurodollar Rate Loans in accordance with Section 9.9
hereof. The Borrower shall give the Agent, no later than 1:00 p.m., Boston time,
at least one (1) Business Day prior written notice of any proposed prepayment
pursuant to this Section 7.3 of Base Rate Loans, and three (3) Eurodollar
Business Days notice of any proposed prepayment pursuant to this Section 7.3 of
Eurodollar Rate Loans, in each case specifying the proposed date of prepayment
of Acquisition Loans and the principal amount to be prepaid. Each such partial
prepayment of the Acquisition Loans shall be in an integral multiple of
$1,000,000 shall be accompanied by the payment of accrued interest on the
principal prepaid to the date of prepayment and shall be applied, in the absence
of instruction by the Borrower, first to the principal of Base Rate Loans and
then to the principal of Eurodollar Rate Loans. Each partial prepayment shall be
allocated among the Banks, in proportion, as nearly as practicable, to the
respective unpaid principal amount of each Bank's Acquisition Note, with
adjustments to the extent practicable to equalize any prior repayments not
exactly in proportion.

                        8. CERTAIN MANDATORY PREPAYMENTS.

        8.1. MANDATORY PREPAYMENTS FROM NEW EQUITY. In the event that the
Borrower shall after the Closing Date sell or issue any shares of its stock,
options or warrants for the purchase of its stock or other equity or equity
instruments (in each case other than (i) stock options or warrants to acquire
stock awarded to employees and directors pursuant to incentive compensation
plans or agreements with such Persons in an aggregate amount for all such
options and warrants not to exceed $250,000, or (ii) stock issued to a seller
party to, and as consideration for, a Permitted Acquisition), then the Borrower
shall, or shall cause 


<PAGE>   57
                                      -50-


such Subsidiary to, immediately prepay the Loans in accordance with Section 8.4
in an amount equal to one hundred percent (100%) of the Net Cash Proceeds of
such sale or issuance of new equity.

        8.2. MANDATORY PREPAYMENTS FROM ADDITIONAL INDEBTEDNESS. In the event
that, after the Closing Date, the Borrower or any of its Subsidiaries shall
incur any Indebtedness, other than Excluded Indebtedness, then the Borrower
shall, or shall cause such Subsidiary to, immediately prepay the Loans in
accordance with Section 8.4 in an amount equal to one hundred percent (100%) of
the Net Cash Proceeds of the incurrence of such Indebtedness.

        8.3. MANDATORY PREPAYMENTS FROM ASSET SALES. Immediately upon the
occurrence of any Asset Disposition or series of Asset Dispositions the Net Cash
Proceeds of which, in any fiscal year of the Borrower, exceed $1,000,000, the
Borrower shall prepay the Loans in accordance with Section 8.4 in an amount
equal to one hundred percent (100%) of the amount by which the Net Cash Proceeds
of such Asset Disposition or series of Asset Dispositions exceeds $1,000,000.

        8.4. APPLICATION OF PROCEEDS; ETC. All mandatory prepayments of the
Loans pursuant to this Section 8 shall be applied first to the Term Loan until
repaid in full and shall be applied against the scheduled installments of
principal due thereon in the inverse order of maturity, second to the
outstanding amount of the Acquisition Loans until repaid in full, and third to
the outstanding amount of the Revolving Credit Loans. Upon each such prepayment
of the Acquisition Loans and the Revolving Credit Loans, the Total Acquisition
Loan Commitment or Total Revolving Credit Commitment, as the case may be, shall
be reduced automatically by the amount of such prepayment, whereupon the
respective Acquisition Loan Commitments and Revolving Credit Commitments, as the
case may be, of the Banks shall be reduced pro rata in accordance with their
respective Acquisition Loan Commitment Percentages or Revolving Credit
Commitment Percentages, as the case may be. Any prepayment of principal of the
Loans in accordance with this Section 8.4 shall include all interest accrued to
the date of prepayment. No amount repaid with respect to the Loans in accordance
with this Section 8.4 may be reborrowed.

                         9. CERTAIN GENERAL PROVISIONS.

        9.1. CLOSING AND OTHER FEES. The Borrower agrees to pay to the Agent for
the account of the Banks the closing fees described in the letter dated as of
the date hereof among the Borrower, the Banks and the Agent (the "Closing Fee
Letter") in accordance with the terms and conditions thereof. The Borrower
further agrees to pay to the Agent and the Arranger the fees described in the
letter dated as of the date hereof among the Agent, the Arranger and the
Borrower (the "Agent's Fee Letter") in accordance with the terms and conditions
thereof.

        9.2.  FUNDS FOR PAYMENTS.  

               9.2.1. PAYMENTS TO AGENT. All payments of principal, interest,
        Reimbursement Obligations, Commitment Fees, Letter of Credit Fees and
        any other amounts due hereunder or under any of the other Loan Documents
        shall be made on the due date thereof to the Agent in Dollars, for the
        respective accounts of the Banks, the Swing Line Bank and the Agent, at
        the Agent's Head Office or at such other location in the Boston,
        Massachusetts area that the Agent may from time to time designate, in
        each case in immediately available funds not later than 11:00 a.m.
        (Boston, Massachusetts, time).

               9.2.2. NO OFFSET, ETC. All payments by the Borrower hereunder
        and under any of the other Loan Documents shall be made without setoff
        or counterclaim and free and clear of and without deduction for any
        taxes, levies, imposts, duties, charges, fees, deductions, withholdings,
        compulsory loans, restrictions or conditions of any nature now or
        hereafter imposed or levied by any jurisdiction or any political
        subdivision thereof or taxing or other authority therein unless the
        Borrower is compelled by law to make such deduction or withholding. If
        any such obligation is imposed upon the Borrower with respect to any
        amount payable by it hereunder or under any of the other Loan Documents,
        the Borrower will pay to the Agent, for the account of the Banks or (as
        the case may be) the Agent, on the date on which such amount is due and
        payable hereunder or under such other Loan Document, such additional
        amount in Dollars as shall be necessary to enable the Banks or the Agent
        to receive the same net amount which the Banks or the Agent would have
        received on such due date had no such obligation been imposed upon the
        Borrower. The Borrower will deliver promptly to the Agent certificates
        or other valid vouchers for all taxes or other charges deducted from or
        paid with respect to payments made by the Borrower hereunder or under
        such other Loan Document.

<PAGE>   59
                                      -52-


        9.3. COMPUTATIONS. All computations of interest on the Loans (other than
Eurodollar Rate Loans), Commitment Fees and Letter of Credit Fees shall be based
on a 360-day year and paid for the actual number of days elapsed. All
computations of interest on Eurodollar Rate Loans shall be based on a 365-day
year and paid for the actual number of days elapsed. Except as otherwise
provided in the definition of the term "Interest Period" with respect to
Eurodollar Rate Loans, whenever a payment hereunder or under any of the other
Loan Documents becomes due on a day that is not a Business Day, the due date for
such payment shall be extended to the next succeeding Business Day, and interest
shall accrue during such extension. The outstanding principal amount of the
Loans as reflected on the Revolving Credit Note Records, the Swing Line Note
Record, the Acquisition Note Records and the Term Note Records from time to time
shall be considered correct and binding on the Borrower absent manifest error
unless within five (5) Business Days after receipt of any notice by the Borrower
of such outstanding amount, the Borrower shall notify the Agent to the contrary.

        9.4. INABILITY TO DETERMINE EURODOLLAR RATE. In the event the Agent
shall determine or be notified by the Majority Banks that adequate and
reasonable methods do not exist for ascertaining the Eurodollar Rate that would
otherwise determine the rate of interest to be applicable to any Eurodollar Rate
Loan during any Interest Period, the Agent shall forthwith give notice of such
determination (which shall be conclusive and binding on the Borrower and the
Banks) to the Borrower and the Banks. In such event (i) any Loan Request or
Conversion Request with respect to Eurodollar Rate Loans shall be automatically
withdrawn and shall be deemed a request for Base Rate Loans, (ii) each
Eurodollar Rate Loan will automatically, on the last day of the then current
Interest Period relating thereto, become a Base Rate Loan, and (iii) the
obligations of the Banks to make Eurodollar Rate Loans shall be suspended until
the Agent or the Majority Banks determines that the circumstances giving rise to
such suspension no longer exist, whereupon the Agent or, as the case may be, the
Agent upon the instruction of the Majority Banks, shall so notify the Borrower
and the Banks.

        9.5. ILLEGALITY. Notwithstanding any other provisions herein, if any
present or future law, regulation, treaty or directive or in the interpretation
or application thereof shall make it unlawful for any Bank to make or maintain
Eurodollar Rate Loans, such Bank shall forthwith give notice of such
circumstances to the Borrower and the other Banks and thereupon (i) the
commitment of such Bank to make Eurodollar Rate Loans or convert Loans of
another Type to Eurodollar Rate Loans shall forthwith be suspended and (ii) such
Bank's Loans then outstanding as Eurodollar Rate Loans, if any, shall be
converted automatically to Base Rate Loans on the last day of each Interest
Period applicable to such 


<PAGE>   60
                                      -53-



Eurodollar Rate Loans or within such earlier period as may be required by law.
The Borrower hereby agrees promptly to pay the Agent for the account of such
Bank, upon demand by such Bank, any additional amounts necessary to compensate
such Bank for any costs incurred by such Bank in making any conversion in
accordance with this Section 9.5, including any interest or fees payable by such
Bank to lenders of funds obtained by it in order to make or maintain its
Eurodollar Rate Loans hereunder.

        9.6. ADDITIONAL COSTS, ETC. If any present or future applicable law,
which expression, as used herein, includes statutes, rules and regulations
thereunder and interpretations thereof by any competent court or by any
governmental or other regulatory body or official charged with the
administration or the interpretation thereof and requests, directives,
instructions and notices at any time or from time to time hereafter made upon or
otherwise issued to any Bank or the Agent by any central bank or other fiscal,
monetary or other authority (whether or not having the force of law), shall:

               (a) subject any Bank or the Agent to any tax, levy, impost, duty,
        charge, fee, deduction or withholding of any nature with respect to this
        Credit Agreement, the other Loan Documents, any Letters of Credit, such
        Bank's Commitments or the Loans (other than taxes based upon or measured
        by the income or profits of such Bank or the Agent), or

               (b) materially change the basis of taxation (except for changes
        in taxes on income or profits) of payments to any Bank of the principal
        of or the interest on any Loans or any other amounts payable to any Bank
        or the Agent under this Credit Agreement or any of the other Loan
        Documents, or

               (c) impose or increase or render applicable (other than to the
        extent specifically provided for elsewhere in this Credit Agreement) any
        special deposit, reserve, assessment, liquidity, capital adequacy or
        other similar requirements (whether or not having the force of law)
        against assets held by, or deposits in or for the account of, or loans
        by, or letters of credit issued by, or commitments of an office of any
        Bank, or

               (d) impose on any Bank or the Agent any other conditions or
        requirements with respect to this Credit Agreement, the other Loan
        Documents, any Letters of Credit, the Loans, such Bank's Commitments, or
        any class of loans, letters of credit or commitments of which any of the
        Loans or such Bank's Commitments forms a part,

<PAGE>   61
                                      -54-



and the result of any of the foregoing is:

                      (i) to increase the cost to any Bank of making, funding,
               issuing, renewing, extending or maintaining any of the Loans or
               such Bank's Commitments or any Letter of Credit, or

                      (ii) to reduce the amount of principal, interest,
               Reimbursement Obligation or other amount payable to such Bank or
               the Agent hereunder on account of such Bank's Commitments, any
               Letter of Credit or any of the Loans, or

                      (iii) to require such Bank or the Agent to make any
               payment or to forego any interest or Reimbursement Obligation or
               other sum payable hereunder, the amount of which payment or
               foregone interest or Reimbursement Obligation or other sum is
               calculated by reference to the gross amount of any sum receivable
               or deemed received by such Bank or the Agent from the Borrower
               hereunder,

then, and in each such case, the Borrower will, upon demand made by such Bank or
(as the case may be) the Agent at any time and from time to time and as often as
the occasion therefor may arise, pay to such Bank or the Agent such additional
amounts as will be sufficient to compensate such Bank or the Agent for such
additional cost, reduction, payment or foregone interest or Reimbursement
Obligation or other sum.

        9.7. CAPITAL ADEQUACY. If after the date hereof any Bank or the Agent
determines that (i) the adoption of or change in any law, governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law) regarding capital requirements for banks or bank holding companies or any
change in the interpretation or application thereof by a court or governmental
authority with appropriate jurisdiction or (ii) compliance by such Bank or the
Agent or any corporation controlling such Bank or the Agent with any law,
governmental rule, regulation, policy, guideline or directive (whether or not
having the force of law) of any such entity regarding capital adequacy, has the
effect of reducing the return on such Bank's or the Agent's Commitments with
respect to any Loans or Letters of Credit to a level below that which such Bank
or the Agent could have achieved but for such adoption, change or compliance
(taking into consideration such Bank's or the Agent's then existing policies
with respect to capital adequacy and assuming full utilization of such entity's
capital) by any amount deemed by such Bank or (as the case may be) the Agent to
be material, then such Bank or the Agent may notify the Borrower of such fact.
To the extent that the amount of such reduction in the return on


<PAGE>   62
                                      -55-



capital is not reflected in the Base Rate or the Eurodollar Rate, as the case
may be, the Borrower agrees to pay such Bank or (as the case may be) the Agent
the amount of such reduction in the return on capital as and when such reduction
is determined upon presentation by such Bank or (as the case may be) the Agent
of a certificate in accordance with Section 9.8 hereof. Each Bank shall allocate
such cost increases among its customers in good faith and on an equitable basis.

        9.8. CERTIFICATE. A certificate setting forth any additional amounts
payable pursuant to Sections 9.6 or 9.7 and a brief explanation of such amounts
which are due, submitted by any Bank or the Agent to the Borrower, shall be
conclusive, absent manifest error, that such amounts are due and owing.

        9.9. INDEMNITY. The Borrower agrees to indemnify each Bank and to hold
each Bank harmless from and against any loss, cost or expense (including any
such loss or expense arising from interest or fees payable by such Bank to
lenders of funds obtained by it in order to maintain its Eurodollar Rate Loans
and including loss of anticipated profits of such Bank) that such Bank may
sustain or incur as a consequence of (i) default by the Borrower in payment of

Eurodollar Rate Loan or the making of any conversion of any such Loan to a Base
Rate Loan on a day that is not the last day of the applicable Interest Period
with respect thereto.

        9.10.  INTEREST AFTER DEFAULT.  

               9.10.1. OVERDUE AMOUNTS. Overdue principal and (to the extent
        permitted by applicable law) interest on the Loans and all other overdue

               9.10.2. AMOUNTS NOT OVERDUE. During the continuance of a Default
        or an Event of Default the principal of the Loans not overdue shall,

        Default has been waived by the Majority Banks pursuant to Section 30,
        bear interest at a rate per annum equal to 


<PAGE>   63
                                      -56-



        the greater of (i) two percent (2%) above the rate of interest otherwise
        applicable to such Loans and (ii) the rate of interest applicable to
        overdue principal pursuant to Section 9.10.1.

                      10.  COLLATERAL SECURITY AND GUARANTIES.  

        10.1. SECURITY OF BORROWER. The Obligations shall be secured by a
perfected first priority security interest (subject only to Permitted Liens
entitled to priority under applicable law) in substantially all of the assets of
the Borrower, whether now owned or hereafter acquired, pursuant to the terms of
the Security Documents to which the Borrower is a party; provided, that the
Borrower shall not be required to pledge to the Agent more than 65% of the
capital stock of any Foreign Subsidiary to the extent that the pledge of more
than 65% of such stock would cause material adverse tax consequences to the
Borrower.

        10.2. GUARANTIES AND SECURITY OF SUBSIDIARIES. The Obligations shall be
guaranteed by all of the Domestic Subsidiaries of the Borrower. The obligations
of such Domestic Subsidiaries shall be secured by a perfected first priority

Subsidiary, pursuant to the terms of the Security Documents to which such
Domestic Subsidiaries are a party.

        10.3. NEGATIVE PLEDGE AND DOUBLE NEGATIVE PLEDGE. The Borrower will not,
nor will it permit any of its Subsidiaries to, (i) grant any lien, security
interest or other encumbrance to any Person other than the Agent for the benefit
of the Banks, except for Permitted Liens, as further provided in Section 13.2 or
(ii) enter into any covenant or agreement with any Person other than the Banks
and the Agent pursuant to which it agrees not to grant any lien, security
interest or other encumbrance in favor of any other Person, as further provided
in Section 13.12. 

                      11. REPRESENTATIONS AND WARRANTIES.

        The Borrower represents and warrants to the Banks and the Agent as

                                      -57-


        failure to be so qualified would not have a materially adverse effect on
        the business, assets or financial condition of the Borrower or such
        Subsidiary.

               11.1.2. AUTHORIZATION. The execution, delivery and performance of
        this Credit Agreement and the other Loan Documents to which the Borrower
        or any of its Subsidiaries is a party and the transactions contemplated
        hereby and thereby (i) are within the corporate authority of such
        Person, (ii) have been duly authorized by all necessary corporate
        proceedings, (iii) do not conflict with or result in any breach or
        contravention of any provision of law, statute, rule or regulation to

        judgment, order, writ, injunction, license or permit applicable to the
        Borrower or any of its Subsidiaries, except where such conflict would

        financial condition of the Borrower and its Subsidiaries (taken as a
        whole), (iv) do not conflict with any provision of the corporate charter
        or bylaws of the Borrower or any of its Subsidiaries, and (v) do not

               11.1.3. ENFORCEABILITY. The execution and delivery of this
        Credit Agreement and the other Loan Documents to which the Borrower or
        any of its Subsidiaries is a party will result in valid and legally
        binding obligations of such Person enforceable against it in accordance
        with the respective terms and provisions hereof and thereof, except as
        enforceability is limited by bankruptcy, insolvency, reorganization,
        moratorium or other laws relating to or affecting generally the
        enforcement of creditors' rights and except to the extent that
        availability of the remedy of specific performance or injunctive relief
        is subject to the discretion of the court before which any proceeding
        therefor may be brought.

        11.2. GOVERNMENTAL APPROVALS. The execution, delivery and performance by
the Borrower and any of its Subsidiaries of this Credit Agreement and the other
Loan Documents to which the Borrower or any of its Subsidiaries is a party, the

consent of, or filing with, any governmental agency or authority other than
those already obtained.

        11.3. TITLE TO PROPERTIES; LEASES. Except as indicated on Schedule 11.3
hereto, the Borrower and its Subsidiaries own or lease, as indicated thereon,

others, including any mortgages, leases, 


<PAGE>   65
                                      -58-



        conditional sales agreements, title retention agreements, liens or other
        encumbrances except Permitted Liens.

        11.4.  FINANCIAL STATEMENTS.  

               11.4.1. FINANCIAL STATEMENTS. There has been furnished to each of
        the Banks a consolidated balance sheet of Borrower and its Subsidiaries
        as at the Balance Sheet Date and the consolidated statements of income
        and cash flows of the Borrower and its Subsidiaries for the fiscal year
        ended on such date, certified by Deloitte & Touche LLP. Such balance
        sheets, statements of income and cash flows have been prepared in
        accordance with generally accepted accounting principles and fairly
        present the financial condition of Borrower as at the close of business
        on the date thereof and the results of operations for the fiscal year
        then ended. There are no contingent liabilities of the Borrower or any
        of its Subsidiaries as of such date involving material amounts required
        to be shown on such balance sheet, known to the officers of the
        Borrower, which were not disclosed in such balance sheets and the notes
        related thereto.

               11.4.2. PROJECTIONS. The projections of the annual operating
        budgets of the Borrower and its Subsidiaries on a consolidated basis,
        balance sheets and cash flow statements for the 1999 through 2004 fiscal
        years, copies of which have been delivered to each Bank prior to the
        Closing Date, and subsequent projections delivered pursuant to Section
        12.4(g), have been prepared in good faith based upon reasonable
        assumptions with respect to general economic, financial and market
        conditions. To the knowledge of the Borrower, no facts exist that
        (individually or in the aggregate) would reasonably be expected to
        result in any material adverse change in any of such projections. The
        projections are based upon estimates and assumptions that the Borrower
        believe are reasonable, have been prepared on the basis of the
        assumptions stated therein and reflect the reasonable estimates of the
        Borrower of the results of operations and other information projected
        therein.

        11.5. NO MATERIAL CHANGES, ETC. Since the Balance Sheet Date there has
occurred no materially adverse change in the financial condition or business of
the Borrower and its Subsidiaries as shown on or reflected in the consolidated
balance sheet of the Borrower and its Subsidiaries as at the Balance Sheet Date,
or the consolidated statement of income for the fiscal year then ended, other
than changes in the ordinary course of business that have not had any materially
adverse effect on the business or financial condition of the Borrower
individually 


<PAGE>   66
                                      -59-



or on the Borrower and its Subsidiaries taken as a whole. Since the Balance
Sheet Date the Borrower has not made any Restricted Payments other than the
repurchase of (i) the Borrower's common stock in the amount of $4,686,000 and
(ii) Subordinated Debt in the principal amount of $4,025,000.

        11.6. FRANCHISES, PATENTS, COPYRIGHTS, ETC. Except as set forth on
Schedule 11.6, each of the Borrower and its Subsidiaries possesses all
franchises, patents, copyrights, trademarks, trade names, licenses and permits,
and rights in respect of the foregoing, adequate for the conduct of its business
substantially as now conducted without known conflict with any rights of others.

        11.7. LITIGATION. Except as set forth in Schedule 11.7 hereto, there are
no actions, suits, proceedings or investigations of any kind pending or
threatened against the Borrower or any of its Subsidiaries before any court,
tribunal or administrative agency or board that, if adversely determined, could
reasonably be expected, either in any case or in the aggregate, to materially
adversely affect the properties, assets, financial condition or business of the
Borrower and its Subsidiaries or materially impair the right of the Borrower and
its Subsidiaries, considered as a whole, to carry on business substantially as
now conducted by them, or result in any substantial liability not adequately
covered by insurance, or for which adequate reserves are not maintained on the
consolidated balance sheet of the Borrower and its Subsidiaries, or which
question the validity of this Credit Agreement or any of the other Loan
Documents, or any action taken or to be taken pursuant hereto or thereto.

        11.8. NO MATERIALLY ADVERSE CONTRACTS, ETC. None of the Borrower nor any
of its Subsidiaries is subject to any charter, corporate or other legal
restriction, or any judgment, decree, order, rule or regulation that has or is
expected in the future to have a materially adverse effect on the business,
assets or financial condition of the Borrower or any of its Subsidiaries. None
of the Borrower nor any of its Subsidiaries is a party to any contract or
agreement that has or is expected, in the judgment of the Borrower's officers,
to have any materially adverse effect on the business of the Borrower or any of
its Subsidiaries or on the ability of any such Person to consummate the
transactions contemplated hereby.

        11.9. COMPLIANCE WITH OTHER INSTRUMENTS, LAWS, ETC. None of the Borrower
nor any of its Subsidiaries is in violation of any provision of its charter
documents, bylaws, or any agreement or instrument to which it may be subject or
by which it or any of its properties may be bound or any decree, order,
judgment, statute, license, rule or regulation, in any of 


<PAGE>   67
                                      -60-



the foregoing cases in a manner that could reasonably be expected to result in
the imposition of substantial penalties or materially and adversely affect the
financial condition, properties or business of the Borrower or any of its
Subsidiaries.

        11.10. TAX STATUS. The Borrower and its Subsidiaries (i) have made or
filed all federal and state income and all other tax returns, reports and
declarations required by any jurisdiction to which any of them is subject, (ii)
have paid all taxes and other governmental assessments and charges shown or
determined to be due on such returns, reports and declarations, except those
being contested in good faith and by appropriate proceedings and (iii) have set
aside on their books provisions reasonably adequate for the payment of all taxes
for periods subsequent to the periods to which such returns, reports or
declarations apply. There are no unpaid taxes in any material amount claimed to
be due by the taxing authority of any jurisdiction from the Borrower or any of
its Subsidiaries, except those being contested in good faith and for which
adequate reserves with respect thereto have been set aside by such Person, and
the officers of the Borrower know of no basis for any such claim.

        11.11. NO EVENT OF DEFAULT. No Default or Event of Default has occurred
and is continuing.

        11.12. HOLDING COMPANY AND INVESTMENT COMPANY ACTS. None of the Borrower
nor any of its Subsidiaries is a "holding company", or a "subsidiary company" of
a "holding company", or an "affiliate" of a "holding company", as such terms are
defined in the Public Utility Holding Company Act of 1935; nor is any such
Person an "investment company", or an "affiliated company" or a "principal
underwriter" of an "investment company", as such terms are defined in the
Investment Company Act of 1940.

        11.13. ABSENCE OF FINANCING STATEMENTS, ETC. Except with respect to
Permitted Liens, there is no financing statement, security agreement, chattel
mortgage, real estate mortgage or other document filed or recorded with any
filing records, registry or other public office, that purports to cover, affect
or give notice of any present or possible future lien on, or security interest
in, any assets or property of the Borrower or any of its Subsidiaries or any
rights relating thereto.

        11.14. PERFECTION OF SECURITY INTEREST. All filings, assignments,
pledges and deposits of documents or instruments have been made and all other
actions have been taken that are necessary or advisable, under applicable law,
to establish and perfect the Agent's first-priority security interest in the
Collateral. The Collateral and the Agent's rights with 

<PAGE>   68
                                      -61-



respect to the Collateral are not subject to any setoff, claims, withholdings or
other defenses. The Borrower or a Subsidiary is the owner of the Collateral free
from any lien, security interest, encumbrance and any other claim or demand,
except for Permitted Liens.

        11.15. CERTAIN TRANSACTIONS. None of the officers, directors, or
employees of the Borrower or any of its Subsidiaries is presently a party to any
transaction with the Borrower or any of its Subsidiaries (other than for
services as employees, officers and directors), including any contract,
agreement or other arrangement relating to the payment of management fees or
providing for the furnishing of services to or by, providing for rental of real
or personal property to or from, or otherwise requiring payments to or from any
officer, director or such employee or, to the knowledge of the Borrower, any
corporation, partnership, trust or other entity in which any officer, director,
or any such employee has a substantial interest or is an officer, director,
trustee or partner.

        11.16.  EMPLOYEE BENEFIT PLANS.  

               11.16.1. IN GENERAL. Each Employee Benefit Plan and each
        Guaranteed Pension Plan has been maintained and operated in compliance
        in all material respects with the provisions of ERISA and, to the extent
        applicable, the Code, including but not limited to the provisions
        thereunder respecting prohibited transactions and the bonding of
        fiduciaries and other persons handling plan funds as required by Section
        412 of ERISA. The Borrower has heretofore delivered to the Agent the
        most recently completed annual report, Form 5500, with all required
        attachments, and actuarial statement required to be submitted under
        Section 103(d) of ERISA, with respect to each Guaranteed Pension Plan.

               11.16.2. TERMINABILITY OF WELFARE PLANS. No Employee Benefit Plan
        which is an employee welfare benefit plan within the meaning of Section
        3(1) or Section 3(2)(B) of ERISA, provides benefit coverage subsequent
        to termination of employment, except as required by Title I, Part 6 of
        ERISA, or applicable state insurance laws. The Borrower or an ERISA
        Affiliate, as appropriate, may terminate each such Plan at any time (or
        at any time subsequent to the expiration of any applicable bargaining
        agreement) in the discretion of the Borrower or such ERISA Affiliate
        without liability to any Person, other than for claims arising prior to
        termination.

               11.16.3. GUARANTEED PENSION PLANS. Each contribution required to
        be made to a Guaranteed Pension Plan, whether required to be made to
        avoid the incurrence of an accumulated funding deficiency, the notice or
        lien provisions of Section 302(f) of ERISA, 


<PAGE>   69
                                      -62-


        or otherwise, has been timely made. No waiver of an accumulated funding
        deficiency or extension of amortization periods has been received with
        respect to any Guaranteed Pension Plan and none of the Borrower nor any
        ERISA Affiliate is obligated to or has posted security in connection
        with an amendment to a Guaranteed Pension Plan pursuant to Section 307
        of ERISA or Section 401(a)(29) of the Code. No liability to the PBGC
        (other than required insurance premiums, all of which have been paid)
        has been incurred by the Borrower or any ERISA Affiliate with respect to
        any Guaranteed Pension Plan and there has not been any ERISA Reportable
        Event, or any other event or condition which presents a material risk of
        termination of any Guaranteed Pension Plan by the PBGC. Based on the
        latest valuation of each Guaranteed Pension Plan (which in each case, if
        required by ERISA, occurred within twelve months of the date of this
        representation), and on the actuarial methods and assumptions employed
        for that valuation, the aggregate benefit liabilities of all such
        Guaranteed Pension Plans within the meaning of Section 4001 of ERISA did
        not exceed the aggregate value of the assets of all such Guaranteed
        Pension Plans, disregarding for this purpose the benefit liabilities and
        assets of any Guaranteed Pension Plan with assets in excess of benefit
        liabilities.

               11.16.4. MULTIEMPLOYER PLANS. Neither the Borrower nor any ERISA
        Affiliate has incurred any material liability (including secondary
        liability) to any Multiemployer Plan as a result of a complete or
        partial withdrawal from such Multiemployer Plan under Section 4201 of
        ERISA or as a result of a sale of assets described in Section 4204 of
        ERISA. Neither the Borrower nor any ERISA Affiliate has been notified
        that any Multiemployer Plan is in reorganization or insolvent under and
        within the meaning of Section 4241 or Section 4245 of ERISA or that any
        Multiemployer Plan intends to terminate or has been terminated under
        Section 4041A of ERISA.

        11.17. USE OF PROCEEDS; REGULATIONS U AND X. The proceeds of the Term
Loan will be used solely to fund the repayment of the Borrower's Indebtedness
under the Prior Credit Agreement and certain other existing Indebtedness
(including lease financings) of the Borrower and certain Subsidiaries. The
proceeds of the Revolving Credit Loans will be used solely for working capital
and general corporate purposes and to cover Reimbursement Obligations in
accordance with Section 2.6.2. The proceeds of the Acquisition Loans will be
used solely to fund (i) the purchase price of Permitted Acquisitions, (ii)
Restricted Capital Expenditures otherwise permitted under this Credit Agreement,
and (iii) the repurchase or redemption of up to $7,000,000 in respect of the
Subordinated Debt. The Borrower will obtain Letters of Credit solely for working
capital purposes and, in the case of the IRB Letter of Credit and


<PAGE>   70
                                      -63-



any replacement therefor issued hereunder, to support the Borrower's obligations
under the Bond Documents. No portion of any Loan is to be used, and no portion
of any Letter of Credit is to be obtained, for the purpose of purchasing or
carrying any "margin security" or "margin stock" as such terms are used in
Regulations U and X of the Board of Governors of the Federal Reserve System, 12
C.F.R. Parts 221 and 224.

        11.18. ENVIRONMENTAL COMPLIANCE. The Borrower has taken all appropriate
steps to investigate the past and present condition and usage of the Real Estate
and the operations conducted thereon and, based upon such diligent
investigation, has determined that, except as set forth on Schedule 11.18:

               (a) none of the Borrower, its Subsidiaries or any operator of the
        Real Estate or any operations thereon is in violation, nor have they
        received from any governmental authority a written allegation of any
        violation of any judgment, decree, order, law, license, rule or
        regulation pertaining to environmental matters, including without
        limitation, those arising under the Resource Conservation and Recovery
        Act ("RCRA"), the Comprehensive Environmental Response, Compensation and
        Liability Act of 1980 as amended ("CERCLA"), the Superfund Amendments
        and Reauthorization Act of 1986 ("SARA"), the Federal Clean Water Act,
        the Federal Clean Air Act, the Toxic Substances Control Act, or any
        state or local statute, regulation, ordinance, order or decree relating
        to health, safety or the environment (hereinafter "Environmental Laws"),
        which violation would have a material adverse effect on the business,
        assets or financial condition of the Borrower or any of its
        Subsidiaries;

               (b) none of the Borrower nor any of its Subsidiaries has
        received notice from any third party including, without limitation, any
        federal, state or local governmental authority, (i) that any of them has
        been identified by the United States Environmental Protection Agency
        ("EPA") as a potentially responsible party under CERCLA with respect to
        a site listed on the National Priorities List, 40 C.F.R. Part 300
        Appendix B; (ii) that any hazardous waste, as defined by 42 U.S.C.
        Section 6903(5), any hazardous substances as defined by 42 U.S.C.
        Section 9601(14), any pollutant or contaminant as defined by 42 U.S.C.
        Section 9601(33) and any toxic substances, oil or hazardous materials or
        other chemicals or substances regulated by any Environmental Laws
        ("Hazardous Substances") which any of them has generated, transported or
        disposed of has been found at any site at which a federal, state or
        local agency or other third party has conducted, or has ordered that any
        of the Borrower or any of its Subsidiaries conduct, a remedial
        investigation, removal 


<PAGE>   71
                                      -64-



        or other response action pursuant to any Environmental Law; or (iii)
        that it is or shall be a named party to any claim, action, cause of
        action, complaint, or legal or administrative proceeding (in each case,
        contingent or otherwise) arising out of any third party's incurrence of
        costs, expenses, losses or damages of any kind whatsoever in connection
        with the release of Hazardous Substances;

               (c) (i) no portion of the Real Estate has been used for the
        handling, processing, storage or disposal of Hazardous Substances except
        in accordance with applicable Environmental Laws; and no underground
        tank or other underground storage receptacle for Hazardous Substances is
        located on any portion of the Real Estate; (ii) in the course of any
        activities conducted by the Borrower or its Subsidiaries or operators of

        used on the Real Estate except in accordance with applicable
        Environmental Laws; (iii) except in accordance with applicable
        Environmental Laws, there have been no Releases or threatened Releases
        of Hazardous Substances on, upon, into or from the properties of the
        Borrower or its Subsidiaries, which releases would have a material
        adverse effect on the value of any of the Real Estate or adjacent
        properties or the environment; (iv) to the best of the Borrower's
        knowledge, there have been no releases on, upon, from or into any real
        property in the vicinity of any of the Real Estate which, through soil
        or groundwater contamination, may have come to be located on, and which
        would have a material adverse effect on the value of, the Real Estate;
        and (v) in addition, any Hazardous Substances that have been generated
        on any of the Real Estate have been transported offsite only by carriers

        facilities have been and are, to the best of the Borrower's knowledge,
        operating in compliance with such permits and applicable Environmental

        Substances site assessments, (ii) remove or remediate Hazardous
        Substances, (iii) give notice to any governmental agency or (iv) record

        11.19. SUBSIDIARIES, ETC. The only Subsidiaries of the Borrower are
listed on Schedule 11.19 hereto. Neither the Borrower nor any Subsidiary of the
Borrower is engaged in any joint venture or partnership with any other Person.

        11.20. BANK ACCOUNTS. Schedule 11.20 (as such Schedule may be updated
from time to time in accordance with Section 13.9) sets forth the account
numbers and location of all bank accounts of the Borrower and each of its
Subsidiaries.

        11.21. SUBORDINATED DEBT DOCUMENTS; BOND DOCUMENTS. The Borrower has
furnished to the Agent true, correct and complete copies of the Subordinated
Debt Documents and the Bond Documents. None of the Subordinated Debt Documents
or the Bond Documents has been amended, modified or supplemented, except as
permitted by Section 13.17. Each of the representations of the Borrower
contained in the Subordinated Debt Documents and the Bond Documents was true and
correct in all material respects when made and continues to be true and correct
in all material respects except to the extent of changes resulting from
transactions contemplated or permitted by the Subordinated Debt Documents or the
Bond Documents, as the case may be, and except for changes occurring in the
ordinary course of business that singly or in the aggregate are not materially
adverse.

        11.22. DISCLOSURE. No representation or warranty made by the Borrower or
any of its Subsidiaries in this Credit Agreement, the other Loan Documents or
any agreement, instrument, document, certificate, or other written statement
furnished to the Agent or any Bank by or on behalf of the Borrower or any of its
Subsidiaries in connection with any of the transactions contemplated hereby
contains any untrue statement of a material fact or omits to state a material
fact necessary in order to make the statements contained therein not misleading
in light of the circumstances in which they are made.

        11.23. FISCAL YEAR. The Borrower has a fiscal year which ends on June 30
of each year and fiscal quarters which end on September 30, December 31, March
31 and June 30 of each year.

        11.24. SOLVENCY. Each of the Borrower, individually, and the Borrower
and its Subsidiaries, taken as a whole (both before and after giving effect to
the transactions contemplated by this Credit Agreement and the other Loan
Documents) (i) is solvent, (ii) has assets having a fair value in excess of its
liabilities, (iii) has assets having a fair value in excess of the amount
required to pay its liabilities on its debts as they become due and matured, and
(iv) has, and expects to continue to have, access to adequate capital for the
conduct of its business and the ability 


<PAGE>   73
                                      -66-



to pay its debts as they mature. In computing the amount of contingent and
unliquidated liabilities at any time, such liabilities will be computed as the
amount which, in light of all the facts and circumstances existing at such time,
represents the amount that is probable to become an absolute and matured
liability.

        11.25. CHIEF EXECUTIVE OFFICES. The Borrower's chief executive office is
located at 5456 McConnell Avenue, Los Angeles, California 90066, at which
location its books and records are kept. The chief executive office of each
subsidiary of the Borrower is located opposite such Person's name on Schedule
11.25, at which location each such Person's books and records are kept.

        11.26. INSURANCE. Each of the Borrower and its Subsidiaries maintains
with financially sound and reputable insurers insurance with respect to its
properties and businesses against such casualties and contingencies as is in
accordance with businesses engaged in similar activities in similar geographic
areas, and in amounts, containing such terms, in such forms and for such
periods, as may be reasonable and prudent and in accordance with the terms of
the Security Agreements.

        11.27. YEAR 2000 PROBLEM. The Borrower and its Subsidiaries have (i)
reviewed the areas within their businesses and operations which could be
adversely affected by failure to become "Year 2000 Compliant" (i.e. that
computer applications, imbedded microchips and other systems used by the
Borrower or any of its Subsidiaries, will be able properly to recognize and
perform properly date-sensitive functions involving certain dates prior to and
any date after December 31, 1999), (ii) developed a detailed plan and timetable
to become Year 2000 Compliant in a timely manner, and (iii) committed adequate
resources to support the Year 2000 plan of the Borrower and its Subsidiaries.
Based upon such review, the Borrower reasonably believes that the Borrower and
its Subsidiaries will become "Year 2000 Compliant" in a timely manner except to
the extent that failure to do so will not have any materially adverse effect on
the business or financial condition of the Borrower or any of its Subsidiaries.

        11.28. GOVERNMENT CONTRACTS. Schedule 11.28 contains a true and correct
list, as of Closing Date, in reasonable detail, of all contracts to which the
Borrower or any of its Subsidiaries is a party under which accounts, chattel
paper or general intangibles included in the Collateral arise from account
debtors that are governmental entities subject to the Federal Assignment of
Claims Act.

               12.5.1. DEFAULTS. The Borrower will promptly, and in any event

               12.5.3. NOTIFICATION OF CLAIMS AGAINST COLLATERAL. The Borrower

        which the Borrower or any of its Subsidiaries is or becomes a party
        involving an uninsured claim against the Borrower or any of its
        Subsidiaries that could reasonably be expected to have a materially
        adverse effect on the Borrower or any of its Subsidiaries or which
        question the validity of the transactions contemplated hereby or any of
        the Loan Documents, and stating the nature and status of such litigation
        or proceedings. The Borrower will, and will cause each of its

        12.6. CORPORATE EXISTENCE; MAINTENANCE OF PROPERTIES. The Borrower will
do or cause to be done all things necessary to preserve and keep in full force
and effect its corporate existence, rights and franchises and those of its
Subsidiaries and will not, and will not cause or permit any of its Subsidiaries
to, convert to a limited liability company. The Borrower (i) will cause all of
its properties and those of its Subsidiaries used or useful in the conduct of
its business or the business of its Subsidiaries to be maintained and kept in
good condition, repair and working order (except for ordinary wear and tear) and
supplied with all necessary equipment, (ii) will cause to be made all necessary
repairs, renewals, replacements, betterments and improvements thereof, all as in
the judgment of the Borrower may be necessary so that the business carried on in
connection therewith may be properly and advantageously conducted at all times,
and (iii) will, and will cause each of its Subsidiaries to, continue to engage
primarily in the businesses now conducted by them and in related businesses;
provided that nothing in this Section 12.6 shall prevent the Borrower from
discontinuing the operation and maintenance of any of its properties or any of
those of its Subsidiaries or from dissolving any Subsidiary of the Borrower if
such discontinuance or dissolution is, in the judgment of the Borrower,
desirable in the conduct of its or their business and does not materially
adversely affect the business of the Borrower and its Subsidiaries on a
consolidated basis.

        12.7. INSURANCE. The Borrower will, and will cause each of its
Subsidiaries to, maintain with financially sound and reputable insurers
insurance with respect to its properties and business against such casualties
and contingencies as shall be in accordance with the general practices of
businesses engaged in similar activities in similar geographic areas and in
amounts, containing such terms, in such forms and for such periods as may be
reasonable and prudent and in accordance with the terms of the Security
Agreements.

        12.8. TAXES. The Borrower will, and will cause each of its Subsidiaries
to, duly pay and discharge, or cause to be paid and discharged, before the same
shall become overdue, all taxes, assessments and other governmental charges
imposed upon it and its real properties, sales and activities, or any part
thereof, or upon the income or profits therefrom, as well as all claims for
labor, materials, or supplies that if unpaid might by law become a lien or
charge upon any of its property; provided that any such tax, assessment, charge,
levy or claim need not be paid if the validity or amount thereof shall currently
be contested in good faith by appropriate proceedings and if the Borrower or
such Subsidiary shall have set aside on its books adequate reserves with respect
thereto; and provided further that the Borrower and each of its Subsidiaries
will pay all such taxes, assessments, charges, levies or 


<PAGE>   79
                                      -72-


claims forthwith upon the commencement of proceedings to foreclose any lien that

        and to discuss the affairs, finances and accounts of the Borrower and
        its Subsidiaries with, and to be advised as to the same by, its and
        their officers, all at such reasonable times and intervals as the Agent
        or any Bank may reasonably request.

               12.9.2. APPRAISALS. Upon the request of the Agent or the Majority
        Banks, the Borrower will from time to time obtain and deliver to the

        orderly liquidation and forced liquidation values of all or any portion
        of the equipment or real estate owned by the Borrower or any of its
        Subsidiaries and (ii) the then current business value of each of the
        Borrower and its Subsidiaries. All such appraisals shall be conducted
        and made at the expense of the Borrower if a Default or Event of Default
        shall have occurred and be continuing and at the expense of the Banks
        (ratably in accordance with their respective portions of the Total
        Commitment) at all other times.

               12.9.3. ENVIRONMENTAL ASSESSMENTS. The Agent may, at the
        discretion of the Agent or at the request of the Majority Banks, for the
        purpose of assessing and ensuring the value of any Mortgaged Property,
        obtain from time to time one or more environmental assessments or audits
        of such Mortgaged Property prepared by a hydrogeologist, an independent
        engineer or other qualified consultant or expert approved by the Agent
        to evaluate or confirm (i) whether any Hazardous Materials are present
        in the soil or water at such Mortgaged Property and (ii) whether the use
        and operation of such Mortgaged Property complies with all Environmental
        Laws. Environmental assessments may include without limitation detailed
        visual inspections of such Mortgaged Property including any and all
        storage areas, storage tanks, drains, dry wells and leaching areas, and
        the taking of soil samples, surface water samples and ground water
        samples, as well as such other investigations or analyses as the Agent
        deems appropriate. All such environmental assessments shall be conducted
        and made 


<PAGE>   80
                                      -73-



        at the expense of the Borrower (x) if a Default or Event of Default
        shall have occurred and be continuing, (y) in the event the Borrower or
        a Subsidiary acquires additional Mortgaged Property pursuant to Section
        12.13; provided that such environmental assessment shall be limited to
        such additional Mortgaged Property, or (z) if the Agent or the Majority
        Banks reasonably believe (pursuant to a notice delivered in accordance
        with Section 12.5.2 or otherwise) that there could be Hazardous
        Materials present in the soil or water at such Mortgaged Property or
        that the use and operation of such Mortgaged Property may not comply
        with all Environmental Laws. At all other times such environmental
        assessments shall be at the expense of the Banks (ratably in accordance
        with their respective portions of the Total Commitment).

               12.9.4. COMMUNICATIONS WITH ACCOUNTANTS. The Borrower authorizes
        the Agent and, if accompanied by the Agent, the Banks to communicate
        directly with the Borrower's independent certified public accountants
        and authorizes such accountants to disclose to the Agent and the Banks
        any and all financial statements and other supporting financial
        documents and schedules including copies of any management letter with
        respect to the business, financial condition and other affairs of the
        Borrower or any of its Subsidiaries; provided that such accountants
        shall not be required to disclose to the Agent or the Banks any
        information that is the subject of a legally privileged communication
        with the Borrower. At the request of the Agent, the Borrower shall
        deliver a letter addressed to such accountants instructing them to
        comply with the provisions of this Section 12.9.4.

        12.10. COMPLIANCE WITH LAWS, CONTRACTS, LICENSES, AND PERMITS. The
Borrower will, and will cause each of its Subsidiaries to, comply with (i) the
applicable laws and regulations wherever its business is conducted, including
all Environmental Laws, (ii) the provisions of its charter documents and
by-laws, (iii) all agreements and instruments by which it or any of its
properties may be bound and (iv) all applicable decrees, orders, and judgments
except, in each case, where the failure to do so would not have a material
adverse effect on the business, assets or financial condition of the Borrower
and its Subsidiaries, taken as a whole. If any authorization, consent, approval,
permit or license from any officer, agency or instrumentality of any government
shall become necessary or required in order that the Borrower or any of its
Subsidiaries may fulfill any of its obligations hereunder or any of the other
Loan Documents to which the Borrower or such Subsidiary is a party, the Borrower
will, or (as the case may be) will cause such Subsidiary to, immediately take or
cause to be taken all reasonable steps within the power of the Borrower or such
Subsidiary to obtain such 


<PAGE>   81
                                      -74-



authorization, consent, approval, permit or license and furnish the Agent and

        terms thereof, or any action at law, suit in equity or other legal
        proceeding to cancel, revoke or rescind any of the Loan Documents shall

        the Borrower, or any of its Subsidiaries party thereto or any of their

        Guaranteed Pension Plan in an aggregate amount exceeding $250,000 and
        (B) could constitute grounds for the termination of such Guaranteed

        Plan; or (ii) the appointment by a United States District Court of a
        trustee to administer such Guaranteed Pension Plan; or (iii) the
        institution by the PBGC of proceedings to terminate such Guaranteed
        Pension Plan;

               (l) the Borrower or any of its Subsidiaries shall be enjoined,
        restrained or in any way prevented by the order of any court or any

        of its Subsidiaries;


<PAGE>   101

               (q) a "Change in Control" under and as defined in the

        under and as defined in the Subordinated Debt Documents shall have been
        made;

               (r) any default or event of default under the Bond Documents
        shall have occurred and be continuing;

               (s) the Borrower shall at any time, directly or indirectly, own

               (t) (i) any person or group of persons (within the meaning of
        Section 13 or 14 of the Securities Exchange Act of 1934, as amended)
        other than the Management Investors, shall have acquired beneficial
        ownership (within the meaning of Rule 13d-3 promulgated by the
        Securities and Exchange Commission under said Act) of (A) 20% or more of
        the outstanding shares of common stock of the Borrower or (B) a greater
        percentage of the outstanding shares of the Common Stock of the Borrower
        than is then owned collectively by the Management Group; or (ii) during

        Borrower;


<PAGE>   102
                                      -95-



then, and in any such event, so long as the same may be continuing, the Agent
may, and upon the request of the Majority Banks shall, by notice in writing to
the Borrower declare all amounts owing with respect to this Credit Agreement,
the Notes and the other Loan Documents and all Reimbursement Obligations to be,
and they shall thereupon forthwith become, immediately due and payable without
presentment, demand, protest or other notice of any kind, all of which are
hereby expressly waived by the Borrower; provided that in the event of any Event
of Default specified in Sections 17.1(g) or 17.1(h), all such amounts shall
become immediately due and payable automatically and without any requirement of
notice from the Agent or any Bank.

        17.2. TERMINATION OF COMMITMENTS. If any one or more of the Events of
Default specified in Section 17.1(g) or Section 17.1(h) shall occur, any unused
portion of the credit hereunder shall forthwith terminate and each of the Banks
shall be relieved of all further obligations to make Loans to the Borrower, the
Swing Line Bank shall be relieved of all further obligations to make Swing Line
Loans to the Borrower and the Agent shall be relieved of all further obligations
to issue, extend or renew Letters of Credit. If any other Event of Default shall
have occurred and be continuing, the Agent may and, upon the request of the
Majority Banks, shall, by notice to the Borrower, terminate the unused portion
of the credit hereunder, and upon such notice being given such unused portion of
the credit hereunder shall terminate immediately and each of the Banks shall be
relieved of all further obligations to make Loans to the Borrower, the Swing
Line Bank shall be relieved of all further obligations to make Swing Line Loans
to the Borrower and the Agent shall be relieved of all further obligations to
issue, extend or renew Letters of Credit. No termination of the credit hereunder
shall relieve any of the Borrower or any of its Subsidiaries of any of the
Obligations.

        17.3. REMEDIES. In case any one or more of the Events of Default shall
have occurred and be continuing, and whether or not the Banks shall have
accelerated the maturity of the Loans pursuant to Section 17.1, each Bank, if
owed any amount that has become due with respect to the Loans or the
Reimbursement Obligations, may, with the consent of the Majority Banks but not
otherwise, proceed to protect and enforce its rights by suit in equity, action
at law or other appropriate proceeding, whether for the specific performance of
any covenant or agreement contained in this Credit Agreement and the other Loan
Documents or any instrument pursuant to which the Obligations to such Bank are
evidenced, including as permitted by applicable law the obtaining of the ex
parte appointment of a receiver, and, if such amount shall have become due, by
declaration or otherwise, proceed to enforce the payment thereof or any other
legal or equitable right of such Bank. No remedy herein conferred upon any Bank
or the Agent or the holder of any Note or 


<PAGE>   103
                                      -96-



purchaser of any Letter of Credit Participation or participating interest in any
Swing Line Loan is intended to be exclusive of any other remedy and each and
every remedy shall be cumulative and shall be in addition to every other remedy
given hereunder or now or hereafter existing at law or in equity or by statute
or any other provision of law.

        17.4. DISTRIBUTION OF COLLATERAL PROCEEDS. In the event that, following
the occurrence or during the continuance of any Default or Event of Default, the
Agent or any Bank, as the case may be, receives any monies in connection with
the enforcement of any the Security Documents, or otherwise with respect to the
realization upon any of the Collateral, such monies shall be distributed for
application as follows:

               (a) First, to the payment of, or (as the case may be) the
        reimbursement of the Agent for or in respect of all reasonable costs,
        expenses, disbursements and losses which shall have been incurred or
        sustained by the Agent in connection with the collection of such monies
        by the Agent, for the exercise, protection or enforcement by the Agent
        of all or any of the rights, remedies, powers and privileges of the
        Agent under this Credit Agreement or any of the other Loan Documents or
        in respect of the Collateral or in support of any provision of adequate
        indemnity to the Agent against any taxes or liens which by law shall
        have, or may have, priority over the rights of the Agent to such monies;

               (b) Second, to all other Obligations in such order or preference
        as the Majority Banks may determine; provided, however, that (i)
        distributions in respect of such Obligations shall be made pari passu
        among Obligations with respect to any fees which may be payable to the
        Agent and all other Obligations, (ii) Obligations owing to the Banks
        with respect to each type of Obligation such as interest, principal,
        fees and expenses, shall be made among the Banks pro rata; and (iii) the
        Agent may in its discretion make proper allowance to take into account
        any Obligations not then due and payable;

               (c) Third, upon payment and satisfaction in full or other
        provisions for payment in full satisfactory to the Banks and the Agent
        of all of the Obligations, to the payment of any obligations required to
        be paid pursuant to Section 9-504(1)(c) of the Uniform Commercial Code
        of the Commonwealth of Massachusetts; and

               (d) Fourth, the excess, if any, shall be returned to the Borrower
        or to such other Persons as are entitled thereto.

                                   18. SETOFF.

<PAGE>   104
                                      -97-



        Regardless of the adequacy of any collateral, during the continuance of
any Event of Default, any deposits or other sums credited by or due from any of
the Banks to the Borrower and any securities or other property of the Borrower
in the possession of such Bank may be applied to or set off by such Bank against
the payment of Obligations and any and all other liabilities, direct, or
indirect, absolute or contingent, due or to become due, now existing or
hereafter arising, of the Borrower to such Bank. Each of the Banks agrees with
each other Bank that (i) if an amount to be set off is to be applied to
Indebtedness of the Borrower to such Bank, other than Indebtedness evidenced by
the Notes held by such Bank or constituting Reimbursement Obligations owed to
such Bank or constituting such Bank's participating interest in any Swing Line
Loans, such amount shall be applied ratably to such other Indebtedness and to
the Indebtedness evidenced by all such Notes held by such Bank or constituting
Reimbursement Obligations owed to such Bank or constituting such Bank's
participating interest in any Swing Line Loans, and (ii) if such Bank shall
receive from the Borrower, whether by voluntary payment, exercise of the right
of setoff, counterclaim, cross action, enforcement of the claim evidenced by the
Notes held by, or constituting Reimbursement Obligations owed to, or the
participating interest in any Swing Line Loans of, such Bank by proceedings
against the Borrower at law or in equity or by proof thereof in bankruptcy,
reorganization, liquidation, receivership or similar proceedings, or otherwise,
and shall retain and apply to the payment of the Note or Notes held by, or
Reimbursement Obligations owed to, or the participating interest in any Swing
Line Loans of, such Bank any amount in excess of its ratable portion of the
payments received by all of the Banks with respect to the Notes held by, and
Reimbursement Obligations owed to, or the participating interest in any Swing
Line Loans of, all of the Banks, such Bank will make such disposition and
arrangements with the other Banks with respect to such excess, either by way of
distribution, pro tanto assignment of claims, subrogation or otherwise as shall
result in each Bank receiving in respect of the Notes held by it or
Reimbursement Obligations owed it or the participating interest in any Swing
Line Loans, its proportionate payment as contemplated by this Credit Agreement;
provided that if all or any part of such excess payment is thereafter recovered
from such Bank, such disposition and arrangements shall be rescinded and the
amount restored to the extent of such recovery, but without interest.

                                 19. THE AGENT.

        19.1.  AUTHORIZATION.  

               (a) The Agent is authorized to take such action on behalf of each
        of the Banks and to exercise all such powers as are hereunder and under
        any of the other Loan Documents and any 


<PAGE>   105
                                      -98-



        related documents delegated to the Agent, together with such powers as
        are reasonably incident thereto, provided that no duties or
        responsibilities not expressly assumed herein or therein shall be
        implied to have been assumed by the Agent.

               (b) The relationship between the Agent and each of the Banks is
        that of an independent contractor. The use of the term "Agent" is for
        convenience only and is used to describe, as a form of convention, the
        independent contractual relationship between the Agent and each of the
        Banks. Nothing contained in this Credit Agreement nor the other Loan
        Documents shall be construed to create an agency, trust or other
        fiduciary relationship between the Agent and any of the Banks.

               (c) As an independent contractor empowered by the Banks to
        exercise certain rights and perform certain duties and responsibilities
        hereunder and under the other Loan Documents, the Agent is nevertheless
        a "representative" of the Banks, as that term is defined in Article 1 of
        the Uniform Commercial Code, for purposes of actions for the benefit of
        the Banks and the Agent with respect to all collateral security and
        guaranties contemplated by the Loan Documents. Such actions include the
        designation of the Agent as "secured party", "mortgagee" or the like on
        all financing statements and other documents and instruments, whether
        recorded or otherwise, relating to the attachment, perfection, priority
        or enforcement of any security interests, mortgages or deeds of trust in
        collateral security intended to secure the payment or performance of any
        of the Obligations, all for the benefit of the Banks and the Agent.

        19.2. EMPLOYEES AND AGENTS. The Agent may exercise its powers and
execute its duties by or through employees or agents and shall be entitled to
take, and to rely on, advice of counsel concerning all matters pertaining to its
rights and duties under this Credit Agreement and the other Loan Documents. The
Agent may utilize the services of such Persons as the Agent in its sole
discretion may reasonably determine, and all reasonable fees and expenses of any
such Persons shall be paid by the Borrower.

        19.3. NO LIABILITY. Neither the Agent nor any of its shareholders,
directors, officers or employees nor any other Person assisting them in their
duties nor any agent or employee thereof, shall be liable for any waiver,
consent or approval given or any action taken, or omitted to be taken, in good
faith by it or them hereunder or under any of the other Loan Documents, or in
connection herewith or therewith, or be responsible for the consequences of any
oversight or error of judgment 


<PAGE>   106
                                      -99-


whatsoever, except that the Agent or such other Person, as the case may be, may
be liable for losses due to its willful misconduct or gross negligence.

        19.4.  NO REPRESENTATIONS.  

               19.4.1. GENERAL. The Agent shall not be responsible for the
        execution or validity or enforceability of this Credit Agreement, the
        Notes, the Letters of Credit, any of the other Loan Documents or any
        instrument at any time constituting, or intended to constitute,
        collateral security for the Notes, or for the value of any such
        collateral security or for the validity, enforceability or
        collectability of any such amounts owing with respect to the Notes, or
        for any recitals or statements, warranties or representations made
        herein or in any of the other Loan Documents or in any certificate or
        instrument hereafter furnished to it by or on behalf of the Borrower or
        any of its Subsidiaries, or be bound to ascertain or inquire as to the
        performance or observance of any of the terms, conditions, covenants or
        agreements herein or in any instrument at any time constituting, or
        intended to constitute, collateral security for the Notes or to inspect
        any of the properties, books or records of the Borrower or any of its
        Subsidiaries. The Agent shall not be bound to ascertain whether any
        notice, consent, waiver or request delivered to it by the Borrower or
        any holder of any of the Notes shall have been duly authorized or is
        true, accurate and complete. The Agent has not made nor does it now make
        any representations or warranties, express or implied, nor does it
        assume any liability to the Banks, with respect to the creditworthiness
        or financial conditions of the Borrower or any of its Subsidiaries. Each
        Bank acknowledges that it has, independently and without reliance upon
        the Agent or any other Bank, and based upon such information and
        documents as it has deemed appropriate, made its own credit analysis and
        decision to enter into this Credit Agreement.

               19.4.2. CLOSING DOCUMENTATION, ETC. For purposes of determining
        compliance with the conditions set forth in Section 15, each Bank that
        has executed this Credit Agreement shall be deemed to have consented to,
        approved or accepted, or to be satisfied with, each document and matter
        either sent, or made available, by the Agent or the Arranger to such
        bank for consent, approval, acceptance or satisfaction, or required
        thereunder to be consented to, approved by, or satisfactory to, such
        Bank, unless an officer of the Agent or the Arranger active on the
        Borrower's account shall have received notice from such Bank prior to
        the Closing Date specifying such Bank's objection thereto and such
        objection shall 


<PAGE>   107
                                     -100-



        not have been withdrawn by notice to the Agent or the Arranger to such
        effect on or prior to the Closing Date.

        19.5.  PAYMENTS.  

               19.5.1. PAYMENTS TO AGENT. A payment by the Borrower to the Agent
        hereunder or any of the other Loan Documents for the account of any Bank
        or the Swing Line Bank shall constitute a payment to such Bank or the
        Swing Lien Bank, as the case may be. The Agent agrees promptly to
        distribute (a) to each Bank such Bank's pro rata share of payments
        received by the Agent for the account of the Banks, and (b) to the Swing
        Line Bank payments received by the Agent for the account to the Swing
        Line Bank, in each case except as otherwise expressly provided herein or
        in any of the other Loan Documents.

               19.5.2. DISTRIBUTION BY AGENT. If in the opinion of the Agent the
        distribution of any amount received by it in such capacity hereunder,
        under the Notes or under any of the other Loan Documents might involve
        it in liability, it may refrain from making distribution thereof until
        its right to make such distribution shall have been adjudicated by a
        court of competent jurisdiction. If a court of competent jurisdiction
        shall adjudge that any amount received and distributed by the Agent is
        to be repaid, each Person to whom any such distribution shall have been
        made shall either repay to the Agent its proportionate share of the
        amount so adjudged to be repaid or shall pay over the same in such
        manner and to such Persons as shall be determined by such court.

               19.5.3. DELINQUENT BANKS. Notwithstanding anything to the
        contrary contained in this Credit Agreement or any of the other Loan
        Documents, any Bank that (i) fails to make available to the Agent its
        pro rata share of any Revolving Credit Loan, Acquisition Loan or the
        Term Loan, fails to make available to the Swing Line Bank its pro rata
        share of any Swing Line Loan, or fails to purchase any Letter of Credit
        Participation or (ii) fails to comply with the provisions of Section 18
        with respect to making dispositions and arrangements with the other
        Banks, where such Bank's share of any payment received, whether by
        setoff or otherwise, is in excess of its pro rata share of such payments
        due and payable to all of the Banks, in each case as, when and to the
        full extent required by the provisions of this Credit Agreement, shall
        be deemed delinquent (a "Delinquent Bank") and shall be deemed a
        Delinquent Bank until such time as such delinquency is satisfied. A
        Delinquent Bank shall be deemed to have assigned any and all payments
        due to it 


<PAGE>   108
                                     -101-


        from the Borrower, whether on account of outstanding Loans, Unpaid
        Reimbursement Obligations, interest, fees or otherwise, to the remaining
        nondelinquent Banks for application to, and reduction of, their
        respective pro rata shares of all outstanding Loans and Unpaid
        Reimbursement Obligations. The Delinquent Bank hereby authorizes the
        Agent to distribute such payments to the nondelinquent Banks in
        proportion to their respective pro rata shares of all outstanding Loans
        and Unpaid Reimbursement Obligations. A Delinquent Bank shall be deemed
        to have satisfied in full a delinquency when and if, as a result of
        application of the assigned payments to all outstanding Loans and Unpaid
        Reimbursement Obligations of the nondelinquent Banks, the Banks'
        respective pro rata shares of all outstanding Loans and Unpaid
        Reimbursement Obligations have returned to those in effect immediately
        prior to such delinquency and without giving effect to the nonpayment
        causing such delinquency.

        19.6. HOLDERS OF NOTES. The Agent may deem and treat the payee of any
Note or the purchaser of any Letter of Credit Participation as the absolute
owner or purchaser thereof for all purposes hereof until it shall have been
furnished in writing with a different name by such payee or by a subsequent
holder, assignee or transferee.

        19.7. INDEMNITY. The Banks ratably agree hereby to indemnify and hold
harmless the Agent and its affiliates from and against any and all claims,
actions and suits (whether groundless or otherwise), losses, damages, costs,
expenses (including any expenses for which the Agent and its affiliates have not
been reimbursed by the Borrower as required by Section 20), and liabilities of
every nature and character arising out of or related to this Credit Agreement,
the Notes, or any of the other Loan Documents or the transactions contemplated
or evidenced hereby or thereby, or the Agent's or such affiliate's actions taken
hereunder or thereunder, except to the extent that any of the same shall be
directly caused by the Agent's or such affiliate's willful misconduct or gross
negligence.

        19.8. AGENT AS BANK. In its individual capacity, BKB shall have the same
obligations and the same rights, powers and privileges with respect to its
Commitments and the Loans made by it, and as the holder of any of the Notes and
as the purchaser of any Letter of Credit Participations, as it would have were
it not also the Agent and the Swing Line Bank.

        19.9. RESIGNATION. The Agent may resign at any time by giving sixty (60)
days prior written notice thereof to the Banks and the Borrower. Upon any such
resignation, the Majority Banks shall have the 


<PAGE>   109
                                     -102-


right to appoint a successor Agent. Unless a Default or Event of Default shall
have occurred and be continuing, such successor Agent shall be reasonably
acceptable to the Borrower. If no successor Agent shall have been so appointed
by the Majority Banks and shall have accepted such appointment within thirty
(30) days after the retiring Agent's giving of notice of resignation, then the
retiring Agent may, on behalf of the Banks, appoint a successor Agent, which
shall be a financial institution having a rating of not less than A or its
equivalent by Standard & Poor's Ratings Group. Upon the acceptance of any
appointment as Agent hereunder by a successor Agent, such successor Agent shall
thereupon succeed to and become vested with all the rights, powers, privileges
and duties of the retiring Agent, and the retiring Agent shall be discharged
from its duties and obligations hereunder. After any retiring Agent's
resignation, the provisions of this Credit Agreement and the other Loan
Documents 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 Agent.

        19.10. NOTIFICATION OF DEFAULTS AND EVENTS OF DEFAULT. Each Bank hereby
agrees that, upon learning of the existence of a Default or an Event of Default,
it shall promptly notify the Agent thereof. The Agent hereby agrees that upon
receipt of any notice under this Section 19.10 it shall promptly notify the
other Banks of the existence of such Default or Event of Default.

        19.11. DUTIES IN THE CASE OF ENFORCEMENT. In case one or more Events of
Default have occurred and shall be continuing, and whether or not acceleration
of the Obligations shall have occurred, the Agent shall, if (i) so requested by
the Majority Banks and (ii) the Banks have provided to the Agent such additional
indemnities and assurances against expenses and liabilities as the Agent may
reasonably request, proceed to enforce the provisions of the Security Documents
authorizing the sale or other disposition of all or any part of the Collateral
and exercise all or any such other legal and equitable and other rights or
remedies as it may have in respect of such Collateral. The Majority Banks may
direct the Agent in writing as to the method and the extent of any such sale or
other disposition, the Banks hereby agreeing to indemnify and hold the Agent
harmless from all liabilities incurred in respect of all actions taken or
omitted in accordance with such directions, provided that the Agent need not
comply with any such direction to the extent that the Agent reasonably believes
the Agent's compliance with such direction to be unlawful or commercially
unreasonable in any applicable jurisdiction. 

                                 20. EXPENSES.

        The Borrower agrees to pay (i) the reasonable costs of producing and

                                     -104-



including, without limitation, (i) any actual or proposed use by the Borrower or
any of its Subsidiaries of the proceeds of any of the Loans or Letters of
Credit, (ii) any actual or alleged infringement of any patent, copyright,
trademark, service mark or similar right of the Borrower or any of its

Obligations.

                         22. SURVIVAL OF COVENANTS, ETC.

        All covenants, agreements, representations and warranties made herein,

its Subsidiaries in connection with the transactions contemplated hereby and the
Loan Documents shall be deemed to have been relied upon by the Banks and the
Agent, notwithstanding any investigation heretofore or hereafter made by any of

Subsidiary hereunder on and as of the date so delivered.

        23. ASSIGNMENT AND PARTICIPATION.

        23.1. CONDITIONS TO ASSIGNMENT BY BANKS. Except as provided herein, each

<PAGE>   113
                                     -106-



               (a) other than the representation and warranty that it is the
        legal and beneficial owner of the interest being assigned thereby free
        and clear of any adverse claim, the assigning Bank makes no
        representation or warranty, express or implied, and assumes no
        responsibility with respect to any statements, warranties or
        representations made in or in connection with this Credit Agreement or
        the execution, legality, validity, enforceability, genuineness,
        sufficiency or value of this Credit Agreement, the other Loan Documents
        or any other instrument or document furnished pursuant hereto or the
        attachment, perfection or priority of any security interest or mortgage,

               (b) the assigning Bank makes no representation or warranty and
        assumes no responsibility with respect to the financial condition of the
        Borrower and its Subsidiaries or any other Person primarily or
        secondarily liable in respect of any of the Obligations, or the
        performance or observance by the Borrower and its Subsidiaries or any
        other Person primarily or secondarily liable in respect of any of the
        Obligations of any of their obligations under this Credit Agreement or
        any of the other Loan Documents or any other instrument or document
        furnished pursuant hereto or thereto;

               (c) such assignee confirms that it has received a copy of this
        Credit Agreement, together with copies of the most recent financial
        statements referred to in Section 11.4 and Section 12.4 and such other
        documents and information as it has deemed appropriate to make its own
        credit analysis and decision to enter into such Assignment and
        Acceptance;

               (d) such assignee will, independently and without reliance upon
        the assigning Bank, the 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 credit decisions in taking or not taking action
        under this Credit Agreement;

               (e) such assignee represents and warrants that it is an Eligible
        Assignee;

               (f) such assignee appoints and authorizes the Agent to take such

        incidental thereto;



<PAGE>   114
                                     -107-


               (g) such assignee agrees that it will perform in accordance with
        their terms all of the obligations that by the terms of this Credit
        Agreement are required to be performed by it as a Bank;

               (h) such assignee represents and warrants that it is legally
        authorized to enter into such Assignment and Acceptance; and

               (i) such assignee acknowledges that it has made arrangements with
        the assigning Bank satisfactory to such assignee with respect to its pro
        rata share of Letter of Credit Fees in respect of outstanding Letters of
        Credit.

        23.3. REGISTER. The Agent shall maintain a copy of each Assignment and
Acceptance delivered to it and a register or similar list (the "Register") for
the recordation of the names and addresses of the Banks and the Commitments and
Commitment Percentages of, and principal amount of the Loans owing to and Letter
of Credit Participations purchased by, the Banks from time to time. The entries
in the Register shall be conclusive, in the absence of manifest error, and the
Borrower, the Agent and the Banks may treat each Person whose name is recorded
in the Register as a Bank hereunder for all purposes of this Credit Agreement.
The Register shall be available for inspection by the Borrower and the Banks at
any reasonable time and from time to time upon reasonable prior notice. Upon
each such recordation, the assigning Bank agrees to pay to the Agent a
registration fee in the sum of $3,500.

        23.4. NEW NOTES. Upon its receipt of an Assignment and Acceptance
executed by the parties to such assignment, together with each Note subject to
such assignment, the Agent shall (i) record the information contained therein in
the Register, and (ii) give prompt notice thereof to the Borrower and the Banks
(other than the assigning Bank). Within five (5) Business Days after receipt of
such notice, the Borrower, at its own expense, shall execute and deliver to the
Agent, in exchange for each surrendered Note, a new Note to the order of such
Eligible Assignee in an amount equal to the amount assumed by such Eligible
Assignee pursuant to such Assignment and Acceptance and, if the assigning Bank
has retained some portion of its obligations hereunder, a new Note to the order
of the assigning Bank in an amount equal to the amount retained by it hereunder.
Such new Notes shall provide that they are replacements for the surrendered
Notes, shall be in an aggregate principal amount equal to the aggregate
principal amount of the surrendered Notes, shall be dated the effective date of
such Assignment and Acceptance and shall otherwise be substantially the form of
the assigned Notes. If requested by such Assignee, within five (5) Business Days
of issuance of any new Notes pursuant to this Section 23.4, the Borrower shall,
at its own expense, deliver an opinion of counsel, addressed to the 


<PAGE>   115
                                     -108-


Banks and the Agent, relating to the due authorization, execution and delivery
of such new Notes and the legality, validity and binding effect thereof, in form
and substance satisfactory to the Banks. The surrendered Notes shall be
cancelled and returned to the Borrower.

        23.5. PARTICIPATIONS. Each Bank may sell participations to one or more
banks or other entities in all or a portion of such Bank's rights and
obligations under this Credit Agreement and the other Loan Documents; provided
that (i) any such sale or participation shall not affect the rights and duties
of the selling Bank hereunder to the Borrower and (ii) the only rights granted
to the participant pursuant to such participation arrangements with respect to
waivers, amendments or modifications of the Loan Documents shall be the rights
to approve waivers, amendments or modifications that would reduce the principal
of or the interest rate on any Loans, extend the term or increase the amount of
the Commitments of such Bank as it relates to such participant, reduce the
amount of any Commitment Fees or Letter of Credit Fees to which such participant
is entitled or extend any regularly scheduled payment date for principal or
interest.

        23.6. DISCLOSURE. The Borrower agrees that in addition to disclosures
made in accordance with standard and customary banking practices any Bank may
disclose information obtained by such Bank pursuant to this Credit Agreement to
assignees or participants and potential assignees or participants hereunder;
provided that such assignees or participants or potential assignees or
participants shall agree (i) to treat in confidence such information unless such
information otherwise becomes public knowledge, (ii) not to disclose such
information to a third party, except as required by law or legal process and
(iii) not to make use of such information for purposes of transactions unrelated
to such contemplated assignment or participation. For purposes of this Section
23.6 an assignee or participant or potential assignee or participant may include
a counterparty with whom such Bank has entered into or potentially might enter
into a derivative contract referenced to credit or other risks or events arising
under this Credit Agreement or any other Loan Document.

        23.7. ASSIGNEE OR PARTICIPANT AFFILIATED WITH THE BORROWER. If any
assignee Bank is an Affiliate of the Borrower, then any such assignee Bank shall
have no right to vote as a Bank hereunder or under any of the other Loan
Documents for purposes of granting consents or waivers or for purposes of
agreeing to amendments or other modifications to any of the Loan Documents or
for purposes of making requests to the Agent pursuant to Section 17.1 or Section
17.2, and the determination of the Majority Banks shall for all purposes of this
Agreement and the other Loan Documents be made without regard to such assignee
Bank's interest in any of the


<PAGE>   116
                                     -109-



Loans or Reimbursement Obligations. If any Bank sells a participating interest
in any of the Loans or Reimbursement Obligations to a participant, and such
participant is the Borrower or an Affiliate of the Borrower, then such
transferor Bank shall promptly notify the Agent of the sale of such
participation. A transferor Bank shall have no right to vote as a Bank hereunder
or under any of the other Loan Documents for purposes of granting consents or
waivers or for purposes of agreeing to amendments or modifications to any of the
Loan Documents or for purposes of making requests to the Agent pursuant to
Section 17.1 or Section 17.2 to the extent that such participation is
beneficially owned by the Borrower or any Affiliate of the Borrower, and the
determination of the Majority Banks shall for all purposes of this Credit
Agreement and the other Loan Documents be made without regard to the interest of
such transferor Bank in the Loans or Reimbursement Obligations to the extent of
such participation.

        23.8. MISCELLANEOUS ASSIGNMENT PROVISIONS. Any assigning Bank shall
retain its rights to be indemnified pursuant to Section 21 with respect to any
claims or actions arising prior to the date of such assignment. If any assignee
Bank is not incorporated under the laws of the United States of America or any
state thereof, it shall, prior to the date on which any interest or fees are
payable hereunder or under any of the other Loan Documents for its account,
deliver to the Borrower and the Agent certification as to its exemption from
deduction or withholding of any United States federal income taxes. Anything
contained in this Section 23 to the contrary notwithstanding, any Bank may at
any time pledge all or any portion of its interest and rights under this Credit
Agreement (including all or any portion of its Notes) to (a) any of the twelve
Federal Reserve Banks organized under Section 4 of the Federal Reserve Act, 12
U.S.C. Section 341 or (b) to a lender to such Bank (or a trustee therefor) in
connection with a bona fide financing transaction. No such pledge or the
enforcement thereof shall release the pledgor Bank from its obligations
hereunder or under any of the other Loan Documents.

        23.9. ASSIGNMENT THE BORROWER. Neither the Borrower nor any of its
Subsidiaries shall assign or transfer any of its rights or obligations under any
of the Loan Documents without the prior written consent of each of the Banks.

                                24. NOTICES, ETC.

amended without the written consent of all of the Banks; (c) the amount of any
fees or Letter of Credit Fees payable for the Agent's account, Sections 5 and 19
may not be amended without the written consent of the Agent; and (d) no
amendment, waiver or consent shall affect the rights and obligations of the
Swing Line Bank without the written consent of the Swing Line Bank in addition
to the Banks required above to take such action. No waiver shall extend to or
affect any obligation not expressly waived or impair any right consequent
thereon. No course of dealing or delay or omission on the part of the Agent or
any Bank in exercising any right shall operate as a waiver thereof or otherwise
be prejudicial thereto. No notice to or demand upon the Borrower shall entitle
the Borrower to other or further notice or demand in similar or other

                               31. SEVERABILITY.

        The provisions of this Credit Agreement are severable and if any one
clause or provision hereof shall be held invalid or unenforceable in whole or in
part in any jurisdiction, then such invalidity or unenforceability shall affect
only such clause or provision, or part thereof, in such jurisdiction, and shall
not in any manner affect such clause or provision in any other jurisdiction, or
any other clause or provision of this Credit Agreement in any jurisdiction.

                               32. CONFIDENTIALITY

        Each of the Banks and the Agent agrees, on behalf of itself and each of
its affiliates, directors, officers, employees and representatives, to use
reasonable precautions to keep confidential, in accordance with their customary

sound banking practices, any non-public information supplied to it by the
Borrower or any of its Subsidiaries pursuant to this Credit Agreement that is
identified by such Person as being confidential at the time the same is
delivered to the Banks or the Agent, provided that nothing herein shall limit
the disclosure of any such information (a) after such information shall have
become public other than through a violation of this Section 32, (b) to the
extent required by statute, rule, regulation or judicial process, (c) to counsel
for any of the Banks or the Agent, (d) to bank examiners or any other regulatory
authority having jurisdiction over any Bank or the Agent, or to auditors or
accountants, (e) to the Agent, any Bank or any of their Affiliates, (f) in
connection with any litigation to which any one or more of the Banks, the Agent
or any such Affiliate is a party, or in connection with the enforcement of
rights or remedies hereunder or under any other Loan Document, or (g) to any
assignee or participant (or prospective assignee or participant) so long as such
assignee or participant agrees to be bound by the provisions of Section 23.6.
The obligations of each Bank under this Section 32 shall supersede and replace
the obligations of such Bank under any confidentiality letter in respect of this
financing signed and delivered by such Bank to the Borrower prior to the date
hereof and shall be binding upon any assignee of, or purchaser of any
participation in, any interest in any of the Loans or Reimbursement Obligations
from any Bank.

except as provided below, on and as of the Closing Date this Credit Agreement
and the other Loan Documents shall supersede the Prior Reimbursement Agreement
and that from and after the Closing Date the rights and obligations of the
parties evidenced by the Prior Reimbursement Agreement shall be evidenced by
this Credit Agreement and the other Loan Documents; provided that the nothing in
this Section 33 shall limit the obligations of the Borrower or the other parties
to the Prior Reimbursement Agreement in respect of paragraphs 7(g), 10(g) or
11(l) thereof or any other provisions of the Prior Reimbursement Agreement that
by their terms survive termination of the Prior Reimbursement Agreement or
payment of the L/C Obligations (as defined in the Prior Reimbursement
Agreement). All letter of credit fees, other fees, interest and expenses, if
any, owing or accrued under or in respect of the Prior Reimbursement Agreement
through the Closing Date shall be calculated as of the Closing Date (pro-rated
in the case of any fractional periods), and shall be paid on the Closing Date.
