Borrower and the Borrower may borrow, repay, and reborrow from time to time
between the Closing Date and the Revolving Credit Loan Maturity Date upon notice
by the Borrower to the Agent given in accordance with ss.2.6, such sums as are
requested by the Borrower up to a maximum aggregate principal amount outstanding
(after giving effect to all amounts requested) at any one time equal to such
Bank's Commitment MINUS such Bank's Commitment Percentage of the sum of the
Maximum Drawing Amount and all Unpaid Reimbursement Obligations, PROVIDED that
the sum of the outstanding amount of the Revolving Credit Loans (after giving
effect to all amounts requested) PLUS the Maximum Drawing Amount and all Unpaid
Reimbursement Obligations shall not at any time exceed the lesser of (i) the
Total Commitment and (ii) the Borrowing Base. The Revolving Credit Loans shall
be made PRO RATA in accordance with each Bank's Commitment Percentage. Each
request for a Revolving Credit Loan hereunder shall constitute a representation
and warranty by the Borrower that the conditions set forth in ss. 12 and ss. 13,
in the case of the initial Revolving

<PAGE>   28

                                      -21-

Credit Loans to be made on the Closing Date, and ss.13, in the case of all other
Revolving Credit Loans, have been satisfied on the date of such request.

     2.2. COMMITMENT FEE. The Borrower agrees to pay to the Agent for the
accounts of the Banks in accordance with their respective Commitment Percentages
a commitment fee calculated at the Applicable Commitment Fee Rate per annum on
the average daily amount during each calendar quarter or portion thereof from
the Closing Date to the Revolving Credit Loan Maturity Date by which the Total
Commitment MINUS the sum of the Maximum Drawing Amount and all Unpaid
Reimbursement Obligations exceeds the outstanding amount of Loans during such
calendar quarter. The 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 Revolving Credit Loan Maturity Date or any earlier date on
which the Commitments shall terminate.

     2.3. CHANGE OF TOTAL COMMITMENT.

          2.3.1. REDUCTION OF TOTAL 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 $500,000 or an integral multiple
     thereof or terminate entirely the unborrowed portion of the Total
     Commitment, whereupon the Commitments of the Banks shall be reduced PRO
     RATA in accordance with their respective 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 ss.2.3.1, 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 commitment fee then accrued on the amount of the reduction.
     No reduction of the Commitments may be reinstated.

          2.3.2. INCREASE OF TOTAL COMMITMENT. Unless a Default or Event of
     Default has occurred and is continuing, the Borrower may request, on more
     than one occasion prior to the Revolving Credit Loan Maturity Date, that
     the Total Commitment be increased subject to the approval of the Agent,
     provided that the Total Commitment shall not in any event exceed
     $125,000,000, PROVIDED, HOWEVER, that (i) any Bank which is a party to this
     Credit Agreement prior to such increase may but shall not be required to
     participate in such increase, (ii) in the event that a new Bank provides
     additional funding under this ss.2.3.2, such new Bank must be reasonably
     acceptable to the Agent and the Borrower, and (iii) the Banks' Commitment
     Percentages shall be correspondingly adjusted, as necessary, to reflect any
     increase in the Total Commitment and SCHEDULE 1 shall be amended to reflect
     such adjustments.

     2.4. THE REVOLVING CREDIT NOTES. The Revolving Credit Loans shall be
evidenced by separate promissory notes of the Borrower in substantially the form
of EXHIBIT B hereto (each a "Revolving Credit Note" and collectively, the

Credit Note shall be payable to the order of each Bank in a principal amount
equal to such Bank's Commitment or, if less, the outstanding amount of all

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

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
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 ss. 6.10,

               (a)  The Borrower shall pay interest on the unpaid principal
     amount of each Revolving Credit Loan made by the Banks to the Borrower from
     the Drawdown Date, until such principal amount is paid in full, at an
     annual rate equal to, (i) with respect to any Base Rate Loan, the Base Rate
     in effect from time to time PLUS the Applicable Base Rate Margin (as set
     forth in ss.2.5(b) (the "Applicable Base Rate Margin")), and (ii) with
     respect to any Eurodollar Rate Loan, the Eurodollar Rate in effect for the
     applicable Interest Period PLUS the Applicable Eurodollar Rate Margin (as
     set forth in ss.2.5(b) (the "Applicable Eurodollar Rate Margin")) (the
     Applicable Base Rate Margin or the Applicable Eurodollar Rate Margin,
     whichever is applicable, is sometimes referred to herein as the "Applicable
     Margin").

               (b)  The Applicable Margin and the Applicable Commitment Fee Rate
     shall be the annual percentage rates in effect from time to time determined
     in accordance with the following provisions of this ss.2.5. The Agent shall
     give notice of the Applicable Margin and the Applicable Commitment Fee Rate
     to the Borrower and the Banks five (5) Business Days after the delivery to
     the Agent of the required quarterly financial statements and compliance
     certificate pursuant to ss.ss.9.4(b) and (c) which quarterly financial
     statements shall include, in reasonable detail, a calculation of the Debt
     Ratio as of the date (the "Ratio Calculation Date") which is the end of the
     quarterly period covered by such quarterly financial statements, based on
     the Debt Ratio as of such

     Ratio Calculation Date, with such determination of the Applicable Margin
     and the Applicable Commitment Fee Rate to be made in accordance with the
     following table:

</TABLE>

               (c)  The Applicable Margin and the Applicable Commitment Fee Rate
     so determined pursuant to the foregoing table shall become effective as of
     the date (the "Adjustment Date") which is the first day of the month which
     immediately follows the date of receipt by the Agent of the applicable
     quarterly financial statements and Compliance Certificates delivered
     pursuant to ss.ss.9.4(b) and (c). The Applicable Margin and the Applicable
     Commitment Fee Rate which becomes effective on each such Adjustment Date
     shall remain in effect (subject to the other provisions of this ss.2.5 and
     except as otherwise provided in ss.6.10 hereof) until the next Adjustment
     Date; PROVIDED, HOWEVER, in the event the Borrower fails to deliver to the
     Agent and the Banks the quarterly financial statements and Compliance
     Certificate in accordance with ss.ss.9.4(b) and (c) prior to any scheduled
     Adjustment Date, the Applicable Margin and the Applicable Commitment Fee
     Rate shall automatically be the highest Applicable Margin and the highest
     Applicable Commitment Fee Rate set forth above commencing on the date which
     would have otherwise been the next Adjustment Date had such financial
     statement and Compliance Certificate been delivered in accordance with
     ss.ss.9.4(b) and (c) and continuing until the next scheduled delivery of
     financial statements and Compliance Certificate. Notwithstanding the
     provisions of the preceding two sentences, if at any time the Debt Ratio as
     of any applicable Ratio Calculation Date was actually a ratio other than
     that ratio on the basis of which the Agent determined the rate of interest
     in effect hereunder on any date, then such interest rate and commitment fee
     determination shall be adjusted retroactively to the appropriate Adjustment
     Date on the basis of such corrected determination of the actual Debt Ratio
     for the four (4) quarter period ended on such Ratio Calculation Date, and
     within ten (10) Business Days after notice thereof in reasonable detail
     requesting a

<PAGE>   31

                                      -24-

     retroactive adjustment of interest and commitment fees previously paid
     given by the Borrower, the Agent or any Bank, the Borrower shall pay to the
     Banks, or the Banks severally, on a ratable basis, shall credit the
     Borrower with, as the case may be, the amount of the appropriate
     retroactive adjustment in respect of such adjusted interest rate and
     commitment fee for any portion of any period as to which interest has been
     paid.

                    (d)  The Borrower promises to pay interest on each Revolving
     Credit Loan in arrears on each Interest Payment Date with respect thereto
     and at maturity of such Loan.

     2.6. REQUESTS FOR REVOLVING CREDIT LOANS. The Borrower shall give to the
Agent written notice in the form of EXHIBIT C hereto (or telephonic notice
confirmed in a writing in the form of EXHIBIT C hereto) of each Revolving Credit
Loan requested hereunder (a "Loan Request") no less than (i) 12:00 noon (Boston
time) 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 Loan. Promptly upon receipt of
any such notice, the Agent shall notify each of the Banks thereof. Each such
notice 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 $100,000 or an integral multiple thereof.

     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 written notice prior to 1:00
     p.m. one (1) Business Day prior to the date of such election; (ii) with
     respect to any such conversion of a Eurodollar Rate Loan into a Revolving
     Credit Loan of another Type, such conversion shall only be made on the last
     day of the Interest Period with respect thereto; (iii) 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 and (iv) no Revolving Credit 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
     Commitment Percentage of such 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 as provided
     herein, PROVIDED

<PAGE>   32

                                      -25-

     that partial conversions 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 Loans of any Type may be continued as such upon the expiration of an
     Interest Period with respect thereto by compliance by the Borrower with the
     notice provisions contained in ss.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
     the 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 Banks promptly when any such automatic conversion
     contemplated by this ss.2.7.2 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 of $100,000.

     2.8. FUNDS FOR REVOLVING CREDIT LOANS.

          2.8.1. FUNDING PROCEDURES. Not later than 2:00 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 its Head Office, in immediately
     available funds, the amount of such Bank's Commitment Percentage of the
     amount of the requested Revolving Credit Loans. Upon receipt from each Bank
     of such amount, and upon receipt of the documents required by ss.ss.12 and
     13 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 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 Commitment
     Percentage of any requested Revolving Credit Loans. As an alternative to
     the foregoing, advances may be made pursuant to cash management
     arrangements satisfactory to the Agent and the Banks.

<PAGE>   33

                                      -26-

          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
     Commitment Percentage of the 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 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 Commitment Percentage of such 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 Commitment Percentage of such 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
     Loans made on such Drawdown Date.

     2.9. CHANGE IN BORROWING BASE. The Borrowing Base shall be determined
monthly (or at such other interval as may be specified pursuant to ss.9.4(e)) by
the Agent by reference to the Borrowing Base Report delivered to the Banks and
the Agent pursuant to ss.9.4(e).

                   3. REPAYMENT OF THE REVOLVING CREDIT LOANS.

     3.1. MATURITY. The Borrower promises to pay on the Revolving Credit Loan
Maturity Date, and there shall become absolutely due and payable on the
Revolving Credit Loan 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 amount of the Revolving Credit Loans, the Maximum Drawing
Amount and all Unpaid Reimbursement Obligations exceeds the lesser of (i) the
Total Commitment and (ii) the Borrowing Base, for more than five (5) consecutive
Business Days, 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 Revolving Credit Loans; and
third, to provide to the Agent cash collateral for Reimbursement Obligations as
contemplated by ss. 5.2(b) and (c). Each payment of any Unpaid Reimbursement
Obligations or prepayment of the

<PAGE>   34

                                      -27-

Revolving Credit Loans shall be allocated among the Banks, in proportion, as
nearly as practicable, to the Reimbursement Obligation owing to each such Bank
or (as the case may be) the respective unpaid principal amount of each Bank's
Note, with adjustments to the extent practicable to equalize any prior payments
or repayments not exactly in proportion. In addition, collections of Accounts
Receivable shall be applied to the Revolving Credit Loans pursuant to cash
management arrangements satisfactory to the Agent and the Banks.

     3.3. OPTIONAL PREPAYMENTS OF REVOLVING CREDIT LOANS. The Borrower shall
have the right, at its election, to prepay the outstanding amount of the
Revolving Credit Loans, as a whole or in part, at any time without penalty or
premium, PROVIDED that the full or partial prepayment of the outstanding amount
of any Eurodollar Rate Loans pursuant to this ss.3.3 may be made only on the
last day of the Interest Period relating thereto. The Borrower shall give the
Agent, no later than 1:00 p.m., Boston time, one (1) Business Day prior to the
date of any proposed prepayment written notice, of any proposed prepayment
pursuant to this ss.3.3 of Base Rate Loans, and three (3) Eurodollar Business
Days notice of any proposed prepayment pursuant to this ss.3.3 of Eurodollar
Rate Loans, in each case, specifying the proposed date of payment of Revolving
Credit Loans and the principal amount to be paid. Each such partial prepayment
of the Revolving Credit Loans shall be in an integral multiple of $100,000,
shall be accompanied by the payment of accrued interest on the principal prepaid
to the date of payment and shall be applied first to the principal of Base Rate
Loans and then to the principal of Eurodollar Rate Loans, at the Borrower's
option. 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 Note, with adjustments to the extent practicable to equalize any
prior prepayments not exactly in proportion.

                                4. THE TERM LOAN.

     4.1. CONVERSION OF REVOLVING CREDIT LOANS; THE TERM LOAN. Subject to the
terms and conditions set forth in this Credit Agreement, including, without
limitation, the satisfaction of the conditions set forth in ss.13 hereof and the
execution and delivery by the Borrower of the Term Notes to the Banks, on the
Revolving Credit Loan Maturity Date the aggregate amount of the outstanding
Revolving Credit Loans shall be converted into a Term Loan in the aggregate
principal amount equal to the aggregate outstanding principal balance of the
Revolving Credit Loans on such date, held severally by the Banks in accordance
with their Commitment Percentages. The Term Loan outstanding after conversion
shall be evidenced by the separate Term Notes (the "Term Notes") of the Borrower
payable to the order of each Bank, each dated as of the Revolving Credit Loan
Maturity Date and in substantially the form of EXHIBIT B-2 hereto, completed
with appropriate insertions. On the Revolving Credit Loan Maturity Date, the
Borrower shall pay to the Agent for the PRO RATA accounts of the Banks, all
interest accrued to such date on the Revolving Credit Loans, together with any
Unpaid Reimbursement Obligations, any commitment fees and other fees payable to
the Agent and the Banks hereunder and, as soon as

<PAGE>   35

                                      -28-

reasonably practicable after such payment, each Bank shall surrender to the
Borrower its Revolving Credit Note against receipt of its Term Note evidencing
the amount of the outstanding Revolving Credit Loans so converted.

     4.2. THE TERM NOTES. Each Term Note shall represent the obligation of the
Borrower to pay to such Bank the principal amount of the Term Loan evidenced by
the Term Note 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
Commitment 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. REPAYMENTS OF THE TERM LOAN. The Borrower promises to pay to the Agent
for the account of the Banks the principal amount of the Term Loan in four (4)
consecutive quarterly installments, each equal as near as possible to 1/4th of
the principal amount of the Term Loan outstanding on the Revolving Credit Loan
Maturity Date, such installments to be due and payable on the last day of each
fiscal quarter of the Borrower, commencing with the fiscal quarter ending June
30, 2001, with a final payment on the Term Loan Maturity Date in an amount equal
to the unpaid balance of the Term Loan.

     4.4. OPTIONAL PREPAYMENT OF TERM LOAN. The Borrower shall have the right at
any time to prepay the Term Notes on or before the Term Loan Maturity Date, as a
whole, or in part, upon not less than seven (7) Business Days prior written
notice to the Agent, without premium or penalty, PROVIDED that (a) each partial
prepayment shall be in the principal amount of $5,000,000 or an integral
multiple thereof, (b) any portion of any Eurodollar Rate Loan which has been
prepaid on any day other than the last day of the Interest Period relating
thereto shall be subject to the payment by the Borrower of any applicable costs
associated with such prepayment as set forth in ss.6.9 hereof, and (c) each
partial prepayment shall 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.

                                      -29-

     4.5. INTEREST ON TERM LOAN.

          4.5.1. NOTIFICATION BY BORROWER. The Borrower shall notify the Agent,
     such notice to be irrevocable, at least four (4) Eurodollar Business Days
     prior to the Drawdown Date of the Term Loan if all or any portion of the
     Term Loan is to be a Eurodollar Rate Loan. After the Term Loan has been
     made, the provisions of ss.2 shall apply MUTATIS MUTANDIS with respect to
     all or any 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.

          4.5.2. AMOUNTS, ETC. Any portion of the Term Loan which is a
     Eurodollar Rate Loan relating to any Interest Period shall be in the amount
     of $5,000,000 or a whole multiple or $1,000,000 in excess thereof. No
     Interest Period relating to the Term Loan or any portion thereof which is a
     Eurodollar Rate Loan 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 is a Base Rate Loan.

                              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 ss.5.1.4 and upon the
     representations and warranties of the Borrower contained herein, agrees, in
     its individual capacity, to issue, extend and renew for the account of the
     Borrower one or more letters of credit prior to the Revolving Credit Loan
     Maturity Date (individually, a "Letter of Credit"), in such form as may be
     requested by the Borrower and agreed to by the Agent; PROVIDED, HOWEVER,
     that, after giving effect to such request, (a) the sum of the aggregate
     Maximum Drawing Amount and all Unpaid Reimbursement Obligations shall not
     exceed Two Million Dollars ($2,000,000) at any one time and (b) the sum of
     (i) the Maximum Drawing Amount on all Letters of Credit, (ii) all Unpaid
     Reimbursement Obligations, and (iii) the amount of all Loans outstanding
     shall not exceed the lesser of (A) the Total Commitment and (B) the
     Borrowing Base.

          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.

                                      -30-

          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 date which
     is fourteen (14) Business Days prior to the Revolving Credit Loan Maturity
     Date. Each Letter of Credit so issued, extended or renewed shall be subject
     to the Uniform Customs or, in the case of a Standby Letter of Credit,
     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 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 ss. 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 ss.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 ss. 5.2.

     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 ss.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 under or pursuant to
     such Letter of Credit, (i) the amount paid by the Agent under or pursuant
     to such Letter of Credit, and (ii) the amount of any customary taxes, fees,
     charges or other reasonable costs and expenses whatsoever incurred by the
     Agent or any Bank in connection with any payment made by the Agent or any
     Bank under, or pursuant to, such Letter of Credit,

          (b)  upon the reduction (but not termination) of the Total 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

<PAGE>   38

                                      -31-

          (c)  upon the termination of the Total Commitment or the acceleration
     of the Reimbursement Obligations with respect to all Letters of Credit in
     accordance with ss.14, an amount equal to the then Maximum Drawing Amount
     of 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. Interest on any and all amounts remaining unpaid by
the Borrower under this ss.5.2 at any time from the date such amounts become due
and payable (whether as stated in this ss.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 ss.6.10 for overdue principal of the
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
ss.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 its Head Office, in immediately available
funds, such Bank's 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 Commitment Percentage of such Unpaid Reimbursement Obligation, TIMES
(iii) a fraction, the numerator of which is the number of days that elapse from
and including the date the Agent paid the draft presented for honor or otherwise
made payment up to but excluding the date on which such Bank's Commitment
Percentage of such Unpaid Reimbursement Obligation shall become immediately
available to the Agent, and the denominator of which is 365. 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 ss.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 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

<PAGE>   39

                                      -32-

and the Banks that the Agent and the Banks shall not be responsible for, and the
Borrower's Reimbursement Obligations under ss. 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 ss. 5.4, the
Agent shall be entitled to rely, and shall be fully protected in relying upon,
any Letter of Credit, draft, writing, resolution, notice, consent, certificate,
affidavit, letter, cablegram, telegram, telecopy, telex or teletype message,
statement, order or other document 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 requested by the Majority Banks 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 Credit 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 Notes or of a
Letter of Credit Participation.

     5.6. LETTER OF CREDIT FEE. The Borrower shall, on the date of issuance or
any extension or renewal of any Letter of Credit and at such other time or times
as such charges are customarily made by the Agent, pay a fee (in each case, a
"Letter of Credit Fee") to the Agent for the accounts of the Banks in respect of
each Letter of Credit equal to the Applicable Rate (as defined below) per annum
of the face amount of such Letter of Credit, PLUS the Agent's customary issuance
fee (which fee shall be solely for the account of the Agent). For the purposes
of this ss.5.6, "Applicable Rate" shall mean the percentage rate per annum then
in effect that the Borrower would pay with respect to Eurodollar Rate Loans as
the Applicable Eurodollar Rate Margin as set forth in ss.2.5 of this Credit
Agreement.

<PAGE>   40

                                      -33-

                         6. CERTAIN GENERAL PROVISIONS.

     6.1. FEES. The Borrower shall pay to the Agent on the Closing Date certain
fees as previously agreed to in writing by and between the Borrower and the
Agent. The Borrower shall pay to the Agent annually in advance, for the Agent's
own account, a non refundable Agent's fee in the amount previously agreed to in
writing by and between the Borrower and the Agent.

     6.2. FUNDS FOR PAYMENTS.

          6.2.1. PAYMENTS TO AGENT. All payments of principal, interest,
     Reimbursement Obligations, Letter of Credit Fees, commitment fees and any
     other amounts due hereunder or under any of the other Loan Documents shall
     be made to the Agent, for the respective accounts of the Banks 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.

          6.2.2. 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.

          6.2.3. COMPUTATIONS. All computations of interest on the Loans and of
     commitment fees and Letter of Credit Fees shall, unless otherwise expressly
     provided herein, be based on a 365-day or 366-day year, as the case may be,
     and paid for the actual number of days elapsed; PROVIDED, HOWEVER that
     interest on Eurodollar Rate Loans shall be based on a 360-day year. 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

<PAGE>   41

                                      -34-

     accrue during such extension. The outstanding amount of the Loans as
     reflected on the Note Records from time to time shall be considered correct
     and binding on the Borrower unless within five (5) Business Days after
     receipt of any notice by the Agent or any of the Banks of such outstanding
     amount, the Borrower shall notify the Agent or such Bank to the contrary.
     All agreements between the Borrower and any guarantor and the Banks are
     hereby expressly limited so that in no contingency or event whatsoever,
     whether by reason of acceleration of maturity of the indebtedness evidenced
     hereby or otherwise, shall the amount paid or agreed to be paid to any Bank
     for the use or the forbearance of the indebtedness evidenced hereby exceed
     the maximum permissible under applicable law. As used herein, the term
     "applicable law" shall mean the law in effect as of the date hereof
     provided, however, that in the event there is a change in the law which
     results in a higher permissible rate of interest, then this Credit
     Agreement shall be governed by such new law as of its effective date. In
     this regard, it is expressly agreed that it is the intent of the Borrower
     and the Banks in the execution, delivery and acceptance of this Credit
     Agreement to contract in strict compliance with the laws of the
     Commonwealth of Massachusetts from time to time in effect. If, under or
     from any circumstances whatsoever, fulfillment of any provision hereof or
     of any of the Loan Documents at the time of performance of such provision
     shall be due, shall involve transcending the limit of such validity
     prescribed by applicable law, then the obligation to be fulfilled shall
     automatically be reduced to the limits of such validity, and if under or
     from circumstances whatsoever a Bank should ever receive as interest an
     amount which would exceed the highest lawful rate, such amount which would
     be excessive interest shall be applied to the reduction of the principal
     balance evidenced hereby and not to the payment of interest.

     6.3. INABILITY TO DETERMINE EURODOLLAR RATE. In the event, prior to the
commencement of any Interest Period relating to any Eurodollar Rate Loan, the
Agent shall determine 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 thereof, become a Base Rate
Loan, and (iii) the obligations of the Banks to make Eurodollar Rate Loans shall
be suspended until the Agent determines that the circumstances giving rise to
such suspension no longer exist, whereupon the Agent shall so notify the
Borrower and the Banks.

     6.4. ILLEGALITY. Notwithstanding any other provisions herein, if any
present or future law, regulation, treaty or directive or change in the

<PAGE>   42

                                      -35-

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 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 ss.6.5, 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.

     6.5. 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 Commitment or the Loans or deposits obtained to fund Loans or
     Letters of Credit (other than taxes based upon or measured by the net
     profit or income 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 the Loans or any other amounts payable to any Bank or the
     Agent under this Credit Agreement or 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, assessment, liquidity, capital adequacy, or reserve or other
     similar requirement (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, the Letters of Credit, the Loans, such Bank's Commitment, or any
     class of loans, letters of credit or commitments of which any of the Loans,
     the Letters of Credit, or such Bank's Commitment forms a part, and the
     result of any of the foregoing is

<PAGE>   43

                                      -36-

               (i)  to increase the cost to any Bank of making, funding,
          issuing, renewing, extending or maintaining any of the Loans or such
          Bank's Commitment 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 Commitment, 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 written 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 the Bank or the Agent for such additional cost, reduction,
     payment or foregone interest, Reimbursement Obligation or other sum.

     6.6. 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 and including any determination by such central bank or
other governmental authority that for purposes of capital adequacy requirements
the Commitments hereunder do not constitute commitments with an original
maturity of one year or less) of any such entity regarding capital adequacy, has
the effect of reducing the return on such Bank's or the Agent's commitment with
respect to any Loans 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 capital is not reflected in
the Base Rate, the Borrower agrees to pay such Bank or (as the case may be) the
Agent for 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 ss. 6.8 hereof.

<PAGE>   44

                                      -37-

Each Bank shall allocate such cost increases among its customers in good faith
and on an equitable basis.

     6.7. CERTIFICATE. A certificate setting forth any additional amounts
payable pursuant to ss.6.6 or 6.7 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.

     6.8. INDEMNITY. The Borrower agrees to indemnify each Bank and to hold each
Bank harmless from and against any loss, cost or expense (including loss of
anticipated profits) that such Bank may sustain or incur as a consequence of (i)
default by the Borrower in payment of the principal amount of or any interest on
any Eurodollar Rate Loans as and when due and payable, 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, (ii)
default by the Borrower in making a borrowing after the Borrower has given (or
is deemed to have given) a Loan Request or a Conversion Request relating thereto
in accordance with ss.2.6 or ss.2.7 or (iii) the making of any payment of a
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, including interest or fees payable by such Bank to lenders
of funds obtained by it in order to maintain any such Loans.

     6.9. OVERDUE AMOUNTS. Overdue principal and (to the extent permitted by
applicable law) interest on the Loans and all other overdue amounts payable
hereunder or under any of the other Loan Documents shall bear interest
compounded monthly and payable on demand at a rate per annum equal to two
percent (2%) above the Base Rate until such amount shall be paid in full (after
as well as before judgment).

                           7. SECURITY AND GUARANTIES.

     7.1. 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 all of the assets of the Borrower (other than
Transferred Assets and the assets which have been transferred pursuant to, or
are subject to a security interest under, any Sale Agreements existing as of the
Closing Date) whether now owned or hereafter acquired, and a pledge of and
perfected first priority lien on all of the issued and outstanding shares of
ACFC pursuant to the terms of the Security Documents to which the Borrower is a
party.

     7.2. GUARANTY AND SECURITY OF ACFC. The Obligations shall also be
guaranteed pursuant to the terms of the Guaranty. The obligations of ACFC under
the Guaranty shall be in turn secured by a perfected first priority security
interest (subject only to Permitted Liens entitled to priority under applicable
law) in all of the assets of ACFC, whether now owned or hereafter acquired,
pursuant to the terms of the Security Documents to which ACFC is a party.

<PAGE>   45

                                      -38-

                       8. REPRESENTATIONS AND WARRANTIES.

         The Borrower and ACFC each represents and warrants to the Banks and the
Agent as follows:

     8.1. CORPORATE AUTHORITY.

          8.1.1. INCORPORATION; GOOD STANDING. Each of the Borrower and its
     Subsidiaries (i) is a corporation duly organized, validly existing and in
     good standing under the laws of its state of incorporation, (ii) has all
     requisite corporate power to own its property and conduct its business as
     now conducted and as presently contemplated, and (iii) is in good standing
     as a foreign corporation and is duly authorized to do business in each
     jurisdiction where such qualification is necessary except where a failure
     to be so qualified would not have a materially adverse effect on the
     business, assets or financial condition of the Borrower or its Subsidiaries
     taken as a whole.

          8.1.2. 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 or is to become 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 which
     the Borrower or any of its Subsidiaries is subject or any judgment, order,
     writ, injunction, license or permit applicable to the Borrower or any of
     its Subsidiaries and (iv) do not conflict with any provision of the
     corporate charter or bylaws of, or any agreement or other instrument
     binding upon, the Borrower or any of its Subsidiaries.

          8.1.3. ENFORCEABILITY. The execution and delivery of this Credit
     Agreement and the other Loan Documents to which the Borrower or any of its
     Subsidiaries is or is to become 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.

     8.2. 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 or is to become a
party and the transactions contemplated hereby and thereby do not require the
approval or consent of, or filing with, any governmental agency or authority
other than those already obtained except to

<PAGE>   46

                                      -39-

the extent financing statements are required to be filed to perfect the security
interest granted pursuant to the Security Documents.

     8.3. TITLE TO PROPERTIES; LEASES. Except as indicated on SCHEDULE 8.3
hereto, the Borrower and its Subsidiaries own all of the assets reflected in the
consolidated balance sheet of the Borrower and its Subsidiaries as at the
Balance Sheet Date or acquired since that date (except property and assets sold
or otherwise disposed of in the ordinary course of business since that date),
subject to no rights of others, including any mortgages, leases, conditional
sales agreements, title retention agreements, liens or other encumbrances except
Permitted Liens.

     8.4. FINANCIAL STATEMENTS AND PROJECTIONS.

          8.4.1. FINANCIAL STATEMENTS. There has been furnished to the Agent a
     consolidated balance sheet of the Borrower and its Subsidiaries as at the
     Balance Sheet Date, and a consolidated statement of income for the fiscal
     year then ended, certified by the Borrower's independent certified public
     accountants. Such balance sheet and statement of income have been prepared
     in accordance with generally accepted accounting principles and fairly
     present the financial condition of the Borrower as at the close of business
     on the date thereof and the results of operations for the fiscal year then
     ended. Other than as set forth on SCHEDULE 8.4.1, there are no contingent
     liabilities of the Borrower or any of its Subsidiaries as of such date
     involving material amounts and of a nature customarily reflected on a
     balance sheet in accordance with generally accepted accounting principles
     consistently applied, known to the officers of the Borrower not disclosed
     in said balance sheet and the related notes thereto.

          8.4.2. 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 2000 and 2001 fiscal years, copies of
     which have been delivered to each Bank, disclose all assumptions made with
     respect to general economic, financial and market conditions used in
     formulating such projections. To the knowledge of the Borrower or any of
     its Subsidiaries, no facts exist that (individually or in the aggregate)
     would result in any material change in any of such projections. The
     projections are based upon reasonable estimates and assumptions, have been
     prepared on the basis of the assumptions stated therein and reflect the
     reasonable estimates of the Borrower and its Subsidiaries of the results of
     operations and other information projected therein.

     8.5. NO MATERIAL ADVERSE 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

<PAGE>   47

                                      -40-

then ended, other than changes in the ordinary course of business that have not
had any materially adverse effect in the aggregate on the business or financial

     other than Permitted Liens.

          (b)  Each of the Contracts is a legal, valid and binding full recourse
     obligation of the Obligor thereunder, enforceable by the Borrower or ACFC
     and their respective assigns against such Obligor in accordance with the
     terms thereof, except as such enforcement may be limited by bankruptcy,
     insolvency, reorganization or similar laws relating to or affecting the

     Contract.

          (d)  Except as enforcement may be limited by bankruptcy, insolvency,
     reorganization or similar laws relating to or affecting the enforcement of
     creditors' rights generally and by equitable principles, the obligation of
     each Obligor to pay all amounts owed under each of the Contracts to which
     such Obligor is a party throughout the term thereof is and will be

     circumstance whatsoever.

          (e)  There will be no facts or circumstances existing as of the
     relevant time which give rise to any right of rescission, offset,
     counterclaim or defense, including the defense of usury, to the obligations
     of any Obligor, including the obligation of such Obligor to pay all amounts
     due thereunder, with respect to any Contract to which such Obligor is a
     party; and neither the operation of any of the terms of any Contract nor

     offset, counterclaim or defense, including the defense of usury (other than
     limitations on enforcement as a result of bankruptcy, insolvency,

<PAGE>   53

          (f)  No Contract, and no provision of any Contract, has been amended,
     terminated, altered, waived or modified since inception in any respect that

     that are consistent with Borrower's past practices, no Contract has been
     satisfied, canceled or subordinated, in whole or in part, or rescinded, nor
     has any instrument been executed that would effect any such satisfaction,

          (g)  No Obligor has been released by the Borrower or ACFC from the
     terms of the related Contract.

          (h)  Each Contract was originated or acquired in (1) in the Borrower's
     ordinary course of business, in accordance with the Borrower's Credit
     Policy or (2) in ACFC's ordinary course of business, in accordance with
     ACFC's Credit Policy. Each Contract is of a type customarily in use in the
     leasing or financing business and has not been found, in the Agent's
     reasonable judgment, to be unacceptable.

          (i)  Each Obligor is a resident of the United States of America and is
     not the Borrower or ACFC or an Affiliate of the Borrower or ACFC.

          (j)  Each Contract requires the Obligor to assume all risk of loss or
     malfunction of the related Equipment, if any. Each Contract requires the
     Obligor to pay all sales, use, property, excise and other similar taxes
     imposed on or with respect to the related Equipment, if any. No Contract
     permits early termination or prepayment, unless the amount required to be
     paid by or on behalf of Obligor in respect thereof is equal to or greater
     than the applicable termination amount as set forth in such Contract. No
     Contract provides for the substitution, exchange or addition of any

     Contract.

          (k)  There are no proceedings or investigations pending against the
     Borrower or ACFC or, to the best of their respective knowledge, threatened
     or otherwise pending before any court, regulatory body, administrative
     agency or other tribunal or government instrumentality (A) asserting the
     invalidity or unenforceability of any Contract, (B) seeking to prevent
     payment and performance of any Contract, or (C) seeking any determination

     validity or enforceability of any Contract.

     obligations on its part required to be performed by it under or in

<PAGE>   54

                                      -47-

     connection with each Contract, and has done nothing to materially impair
     its rights thereunder.

          (m)  Each Contract is either an "account" (as defined in Section 9-106
     of the UCC) or "chattel paper" (as defined in Section 9-105 of the UCC) or
     an "instrument" (as defined in Section 9-105 of the UCC). If the Contract
     is chattel paper, then (i) there is only one counterpart of the Contract
     that constitutes "chattel paper" for purposes of Section 9-105(b) and 9-308
     of the UCC and (ii) either the Borrower or ACFC, as applicable, has a first
     priority security interest in the Equipment that is the subject of the
     Contract.

          (n)  Each Contract requires the related Obligor to maintain the
     related Equipment, if any, in good and workable order. Each Contract
     requires the related Obligor to obtain and maintain physical damage
     insurance on the Equipment subject thereto, if any, and to name the lessor
     or lender thereunder as loss payee and an additional insured with respect
     thereto. The Agent is named as loss payee under all of the Borrower's or
     ACFC's physical damage insurance on the Equipment, if any (other than
     insurance of the Borrower or ACFC maintained under Borrower's or ACFC's
     lessee insurance program, as the case may be, pursuant to equipment leases
     with its lessees). To the best of the Borrower's and ACFC's knowledge, the
     Equipment, if any, was properly delivered to each Obligor in good repair,
     without defects and in satisfactory order and the related Equipment, if
     any, is in good operating condition and repair. To the best of the
     Borrower's and ACFC's knowledge, the related Equipment, if any was accepted
     by the Obligor after reasonable opportunity to inspect and test the same
     and no Obligor has informed the Borrower or ACFC of any defects therein.

          (o)  No Contract constitutes a "consumer lease" under the UCC.

          (p)  The Borrower and ACFC have marked their computer records to
     reflect the interest granted to the Agent hereunder.

          (q)  Each Contract permits the rights with respect to such Contract,
     and all collateral related thereto, to be assigned by either the Borrower
     or ACFC, as applicable, without the consent of any Person.

          (r)  The Borrower or ACFC, as applicable, shall have taken actions
     with respect to the collateral in respect of each Contract related to any
     Account Receivable which has an outstanding balance equal to or greater
     than $5,000 as is necessary to insure that the Borrower or ACFC, as
     applicable, maintains, as against the Obligor thereunder a perfected
     security interest in any collateral of the Obligor relating thereto free
     and clear of adverse claims, or in the case of any Lease, to ensure that
     the Borrower or ACFC, as the case may be, would maintain such a perfected
     security interest in the event that a court or other Person were to
     determine that such Lease purported to transfer to the Obligor an

<PAGE>   55

                                      -48-

     ownership (rather than a leasehold) interest in the Equipment subject
     thereto.

          (s)  The Borrower or ACFC, as applicable, shall have taken actions
     with respect to the Accounts Receivable to ensure that the Agent, for the
     benefit of itself and the Banks, has a priority perfected security interest
     in such Accounts Receivable free and clear of any adverse claims,
     including, without limitation, delivery of any applicable Contract Files.

     8.22. SUBORDINATED DEBT. The Obligations constitute "Secured Portfolio
Debt" under the terms of the Indenture and are entitled to the full benefit of
the subordination provisions contained in Article XI of the Indenture.

     8.23. YEAR 2000 COMPLIANCE. The Borrower has reviewed all material areas
within its business and operations which could be adversely affected by, and has
developed and implemented a program to address on a timely basis, the Year 2000
Compliance. Based on such review and program, the Year 2000 Compliance should
not have a material adverse effect on its business and operations.

                    9. AFFIRMATIVE COVENANTS OF THE BORROWER.

     The Borrower and ACFC each covenants and agrees that, so long as any Loan,
Unpaid Reimbursement Obligation, Letter of Credit or Note is outstanding or any

presentations and demands to or upon the Borrower and its Subsidiaries in
respect of the Loan Documents may be given or made. ACFC will maintain its chief
executive office in West Hartford, Connecticut, or at such other place in the
United States of America as ACFC shall designate upon written notice to the
Agent, where notices, presentations and demands to or upon ACFC in respect of
the Loan Documents may be given or made.

     9.3. RECORDS AND ACCOUNTS. The Borrower will (i) keep, and cause each of
its Subsidiaries to keep, true and accurate records and books of account in

contingencies, and other reserves in accordance with generally accepted
accounting principles.

     9.4. FINANCIAL STATEMENTS, CERTIFICATES AND INFORMATION. The Borrower will

     consolidated balance sheet of the Borrower and its Subsidiaries and the
     consolidating balance sheet of the Borrower and its Subsidiaries, each as

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

(iii) all agreements and instruments by which it or any of its properties may be
bound and (iv) all applicable decrees, orders, and judgments; PROVIDED, HOWEVER,

<PAGE>   61

                                      -54-

material adverse effect on the business or financial condition of the Borrower

the event any such proceeds are received, by any of them to receive and hold in
trust for the Agent and the Banks all payments constituting proceeds of Accounts
Receivable or other Collateral which come into their possession or under their

the Borrower or ACFC, as applicable, maintains against the Obligor thereunder a
perfected security interest in any collateral of the Obligor relating thereto
free and clear of adverse claims, or in the case of

<PAGE>   62

                                      -55-

any Lease, to ensure that the Borrower or ACFC, as the case may be, would
maintain such a perfected security interest in the event that a court or other
Person were to determine that such Lease purported to transfer to the Obligor an
ownership (rather than a leasehold) interest in the Equipment subject thereto.

     9.16. PERFORMANCE AND COMPLIANCE WITH RECEIVABLES AND CONTRACTS. The
Borrower and ACFC, as applicable, shall at its own expense timely and fully
perform and comply in all material respects, with all material provisions,

officer of a Bank as to the loss, theft, destruction or mutilation of a Note or
any other security document which is not of public record, and, in the case of
any such loss, theft, destruction or mutilation, upon cancellation of such Note
or other security document, the Borrower will issue, in lieu thereof, a

     redeemed or repurchased in whole or in part; PROVIDED, HOWEVER, that (A)
     early termination of the Bravo Credit Agreement by Bravo pursuant to the
     terms thereof shall not constitute an acceleration by such holders; (B)
     payments by Bravo pursuant to Sections 2.05(b) and 2.05(c) of the Bravo
     Purchase Agreement or Sections 2.04(d) or 2.04(e) of the Bravo Lease

     Subordinated Debt pursuant to Section 4.16 of the Senior Subordinated Note
     Indenture that do not exceed (i) $250,000 in principal amount (plus accrued

     in any calendar year or (ii) $25,000 in principal amount (plus accrued
     interest) in the aggregate with respect to any single holder of
     Subordinated Debt in any calendar year, shall not constitute a Default or
     Event of Default pursuant to this subsection 14.1(j);

     determination that, or issue a judgment, order, decree or ruling to the
     effect that, any one or more of the Loan Documents is illegal, invalid or
     unenforceable in accordance with the terms thereof;

          (l) with respect to any Guaranteed Pension Plan, an ERISA Reportable
     Event shall have occurred and the Majority Banks shall have determined in
     their reasonable discretion that such event reasonably could be expected to
     result in liability of the Borrower or any of its Subsidiaries to the PBGC
     or such Guaranteed Pension Plan in an aggregate amount exceeding $100,000
     and such event in the circumstances occurring reasonably could constitute
     grounds for the termination of such Guaranteed Pension Plan by the PBGC or
     for the appointment by the appropriate United States District Court of a
     trustee

<PAGE>   76

                                      -69-

          (n) there shall occur any material damage to, or loss, theft or
     destruction of, any Collateral, whether or not insured, or any strike,

     (15) consecutive days, the cessation or substantial curtailment of revenue
     producing activities at any facility of the Borrower or any of its
     Subsidiaries if such event or circumstance is not covered by business

     as a whole;

          (o) there shall occur the loss, suspension or revocation of, or
     failure to renew, any license or permit now held or hereafter acquired by

     business or financial condition of the Borrower and its Subsidiaries, taken
     as a whole;

          (p) the Borrower or any of its Subsidiaries shall be indicted for a
     state or federal crime, or any civil or criminal action shall otherwise
     have been brought against the Borrower or any of its Subsidiaries, a
     punishment for which in any such case could include the forfeiture of any
     assets of the Borrower or such Subsidiary included in the Borrowing Base or
     any assets of the Borrower or such Subsidiary not included in the Borrowing
     Base but having a fair market value in excess of $100,000;

          (q) any person or group of persons (within the meaning of Section 13
     or 14 of the Securities Exchange Act of 1934, as amended) shall have
     acquired beneficial ownership (within the meaning of Rule 13d-3 promulgated
     by the Securities and Exchange Commission under said Act) of fifty-one

     Borrower or any "Change in Control" shall occur under the terms of the
     Indenture;

          (r) the occurrence of a Bravo Event of Termination and the expiration
     of any applicable cure period available to Bravo under the Bravo Purchase
     Agreement or a Wind-Down Event and the expiration of

<PAGE>   77

                                      -70-

     any applicable cure period available to Bravo under the Bravo Facility
     Documents;

          (s) the occurrence of any default or any event of default under any of

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, 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 ss.14.1(g), 14.1(h), 14.1(j) or 14.1(q), all such
amounts shall become immediately due and payable automatically and without any
requirement of notice from the Agent or any Bank.

     14.2. TERMINATION OF COMMITMENTS. If any one or more of the Events of
Default specified in ss.14.1(g), ss.14.1(h), ss.14.1(j) or 14.1(q) shall occur,
any unused portion of the credit hereunder shall forthwith terminate and each of
the Banks shall be relieved of all obligations to make 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, or if on any Drawdown Date the conditions precedent to the making of
the Loans to be made on such Drawdown Date or (as the case may be) to issuing,
extending or renewing such Letters of Credit on such date are not satisfied, 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 and the Agent shall be relieved of all further obligations to
issue, extend or renew Letters of Credit. If any such notice is given to the
Borrower the Agent will forthwith furnish a copy thereof to each of the Banks.
No termination of the credit hereunder shall relieve the Borrower of any of the
Obligations or any of its existing obligations to any of the Banks arising under
other agreements or instruments.

<PAGE>   78

                                      -71-

     14.3. REMEDIES. In case any one or more of the Events of Default shall have
occurred and be continuing, and whether or not the Agent shall have accelerated
the maturity of the Loans pursuant to ss.14.1, each Bank, if owed any amount
with respect to the Loans or the Reimbursement Obligations, may 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 purchaser of any Letter of Credit
Participation 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.

     14.4. 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 or any of the Banks for or in respect of all
     reasonable costs, expenses, disbursements and losses which shall have been
     incurred or sustained by the Agent or any of the Banks in connection with
     the collection of such monies by the Agent or any of the Banks, for the
     exercise, protection or enforcement by the Agent or any of the Banks of all
     or any of the rights, remedies, powers and privileges of the Agent or any
     of the Banks under this Credit Agreement or any of the other loan documents
     or in respect of the collateral and supports the provision of adequate
     indemnity to the Agent or any of the Banks against all taxes or liens which
     by law shall have, or may have, priority over the rights of the Agent or
     any of the Banks to such monies;

          (b) Second, to all other Obligations in such order or preference as
     the Majority Banks may determine; PROVIDED, HOWEVER, that distributions in
     respect of such Obligations shall be made (i) PARI PASSU among Obligations
     with respect to the Agent's fee payable under ss.4.1 and all other
     Obligations and (ii) with respect to each type of Obligation owing to the
     Banks such as interest, principal, fees and expenses, among the Banks PRO
     RATA; and PROVIDED, FURTHER, that the Agent may in its discretion make
     proper allowance to take into account any Obligations not then due and
     payable;

<PAGE>   79

                                      -72

          (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 ss. 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.

                                   15. SETOFF.

     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, 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, 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, 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, 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, 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, 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.

                                 16. THE AGENT.

     16.1. 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 related documents delegated to the
Agent, together with such powers as are reasonably incident thereto,

<PAGE>   80

                                      -73-

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. 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.

     (c) Each of the Banks and the Agent acknowledge and agree that (i) the
Agent is authorized to release the security interest created by the Security
Documents in the Bravo Transferred Assets and that (ii) the Agent is authorized
to execute and deliver, on behalf of the Banks and the Agent, such partial
releases under the Uniform Commercial Code as may be necessary or desirable to
accomplish a release of the security interest created by the Security Documents
in the Bravo Transferred Assets. Each of the Banks and the Agent further
acknowledge and agree that (i) the Agent is authorized, from time to time, to
release the security interest created by the Security Documents in any assets
sold or otherwise transferred by the Borrower pursuant to the Sale Agreements
and that (ii) the Agent is authorized to execute and deliver, on behalf of the
Banks and the Agent, such partial releases under the Uniform Commercial Code as
may be necessary or desirable to accomplish a release of the security interest
created by the Security Documents in the assets sold or otherwise transferred by
the Borrower pursuant to the Sale Agreements. Each of the Banks and the Agent
acknowledge and agree that (i) the Agent is authorized to release the security
interest created by the Security Documents in the Capital Transferred Assets and
that (ii) the Agent is authorized to execute and deliver, on behalf of the Banks
and the Agent, such partial releases under the Uniform Commercial Code as may be
necessary or desirable to accomplish a release of the security interest created
by the Security Documents in the Capital Transferred Assets.

     16.2. 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

<PAGE>   81

                                      -74-

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.

     16.3. 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 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.

     16.4. NO REPRESENTATIONS. The Agent shall not be responsible for the
execution or validity or enforceability of this Credit Agreement, the Notes, any
of the other Loan Documents or any instrument at anytime 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
collectibility 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 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 credit
worthiness 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. For purposes of determining compliance with the conditions set
forth in ss.12, 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 to such Bank
for consent, approval, acceptance or satisfaction, or required thereunder to be
consented to or approved by or acceptable or satisfactory to such Bank, unless
an officer of the Agent active upon 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 not have been withdrawn by notice to the Agent
to such effect on or prior to the Closing Date.

<PAGE>   82

                                      -75-

     16.5. PAYMENTS.

          16.5.1. 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
     shall constitute a payment to such Bank. The Agent agrees promptly to
     distribute to each Bank such Bank's PRO RATA share of payments received by
     the Agent for the account of the Banks except as otherwise expressly
     provided herein or in any of the other Loan Documents.

          16.5.2. 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 until its right to make
     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.

          16.5.3. DELINQUENT BANKS. Notwithstanding anything to the contrary
     contained in this Credit Agreement or any of the other Loan Documents, any
     Bank that fails (i) to make available to the Agent its PRO RATA share of
     any Loan or to purchase any Letter of Credit Participation or (ii) to
     comply with the provisions of ss.15 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 (i) shall be deemed to have assigned any and all
     principal payments due to it from the Borrower, whether on account of
     outstanding Loans or Unpaid Reimbursement Obligations, to the remaining
     nondelinquent Banks for application to, and reduction of, their respective
     PRO RATA shares of all outstanding Loans and Unpaid Reimbursement
     Obligations and (ii) shall not be entitled to vote on any matter requiring
     Majority Bank approval and there shall be excluded from the determination
     of Majority Banks at such time (a) the aggregate outstanding amount of
     Notes held by such Delinquent Bank at such time and (b) if no such
     principal is outstanding, the aggregate Commitment of such Delinquent Bank
     at such time. 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

<PAGE>   83

                                      -76-

     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.

     16.6. 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
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.

     16.7. 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 or such affiliate has not
been reimbursed by the Borrower as required by ss.17), 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 willful misconduct or gross negligence.

     16.8. AGENT AS BANK. In its individual capacity, Fleet shall have the same
obligations and the same rights, powers and privileges in respect to its
Commitment and the Loans made by it, and as the holder of any of the Notes, as
it would have were it not also the Agent.

     16.9. 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 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
Corporation. 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.

     16.10. NOTIFICATION OF DEFAULTS AND EVENTS OF DEFAULT. Each Bank hereby
agrees that, upon learning of the existence of a Default or an Event of

<PAGE>   84

                                      -77-

Default, it shall promptly notify the Agent thereof. The Agent hereby agrees
that upon receipt of any notice under this ss.16.10 it shall promptly notify the
other Banks of the existence of such Default or Event of Default.

     16.11. DUTIES IN THE CASE OF ENFORCEMENT. In case one of 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 exercise all or any legal and equitable and other
rights or remedies on behalf of, and for the account of each bank, and enforce
the provisions of the Loan Documents; provided that each Bank shall retain its
rights under ss.14.3. The Majority Banks may direct the Agent in writing as to
the exercise of such rights and remedies and as to the method and the extent of

in any of the 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

withholding of any United States federal income taxes. If any Reference Bank
transfers all of its interest, rights and obligations under this Credit
Agreement, the Agent shall, in consultation with the Borrower and with the
consent of the Borrower and the Majority Banks, appoint another Bank to act as a
Reference Bank hereunder. Anything contained in this ss. 18 to the contrary

ss.30. On the Closing Date, the rights and obligationS of the parties under the
Prior Loan Agreement and the "Notes" as defined therein shall be subsumed within
and be governed by this Credit Agreement and the Notes; PROVIDED, HOWEVER, that
each of the " Loans" (as defined in the Prior Loan Agreement) outstanding under
the Prior Loan Agreement on the Closing Date shall, for purposes of this Credit
Agreement, be Loans.

     30.2. RETURN AND CANCELLATION OF NOTES. Upon its receipt of the Notes to be
delivered hereunder on the Closing Date, each Bank will promptly return to the
Borrower, marked "Canceled", the notes of the Borrower held by such Bank
pursuant to the Prior Loan Agreement, if any.

     30.3. INTEREST AND FEES UNDER SUPERSEDED AGREEMENT. All interest and all
commitment, facility and other fees and expenses owing or accruing under or in
respect of the Prior Loan Agreement shall be calculated as of the Closing Date
(prorated in the case of any fractional periods), and shall be paid on the
Closing Date in accordance with the method specified in the Prior Loan
Agreement, as if the Prior Loan Agreement were still in effect.

     30.4. NO CLAIMS UNDER PRIOR LOAN AGREEMENT. Each Bank wishes (and the
Borrower agrees) to eliminate any possibility that any past conditions, acts,
omissions, events, circumstances or matters would impair or otherwise adversely
affect such Bank's rights, interests, contracts, collateral security or
remedies. Therefore, the Borrower unconditionally releases, waives and forever
discharges (i) any and all liabilities, obligations, duties, promises or
indebtedness of any kind of such Bank to the Borrower regarding the execution,
delivery or performance of the Prior Loan Agreement or any of the other Loan
Documents (as defined in the Prior Loan Agreement), except the obligations to be
performed by such Bank for the Borrower as expressly stated in this Credit
Agreement and the other Loan Documents (as defined in this Credit Agreement),
and (ii) all claims, offsets, causes of action, suits or defenses of any kind
whatsoever (if any), whether known or unknown, which the Borrower might
otherwise have against such Bank or any of its directors, offices, employees or
agents, in either case (i) or (ii), on account of any condition, act, omission,
event, contract, liability, obligation, indebtedness, claim cause of action,
defense, circumstance or matter of any kind whatsoever which existed, arose or
occurred at any time prior to the date hereof regarding the execution, delivery
or performance of the Prior Loan Agreement or any of the Loan Documents (as
defined in the Prior Loan Agreement).

     30.5. INTERBANK SETTLEMENTS. On the Closing Date, each of the Banks shall
pay to each of the other Banks such amounts as may be necessary so as to

                                      -88-

result in the outstanding amount of Loans made by each Bank being equal to such
Bank's Commitment Percentage of the aggregate amount of Loans outstanding as of
the Closing Date. The Borrower and the Banks hereby agree that all amounts paid
to any Bank by any other Bank in connection with interbank settlements with
respect to Loans outstanding immediately prior to the date hereof shall be
deemed to constitute Loans under the Credit Agreement.
