to the Borrowers and the Borrowers may borrow, repay, and reborrow from time to

Obligations, provided that the sum of the outstanding amount of the Revolving
             --------

                                                            ----
Drawing Amount and all Unpaid Reimbursement Obligations shall not at any time
exceed the lesser of (i) the Total Commitment at such time and (ii) the

                                                                      --- ----

calculated at a rate equal to the Applicable Margin then in effect with respect
to Commitment Fees per annum on the average daily amount during each calendar
month or portion thereof from the date hereof to the 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 Revolving Credit
Loans during such calendar month. The Commitment Fee shall be payable monthly in
arrears on the first day of each calendar month for the immediately preceding
calendar month commencing on the first such date following the date hereof, with
a final payment on the Maturity Date or any earlier date on which the
Commitments shall terminate.

     2.3. Reduction of Total Commitment. The Borrowers shall have the right at
          -----------------------------
any time and from time to time upon thirty (30) days prior written notice to the
Administrative Agent to reduce by a minimum amount of $5,000,000 and increments
of $1,000,000 in excess thereof or to terminate entirely the Total Commitment,
whereupon the Commitments of the Lenders 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

Agent will notify the Lenders of the

<PAGE>

                                      -31-

substance thereof. Upon the effective date of any such reduction or termination,
the Borrowers shall pay to the Administrative Agent, for the respective accounts
of the Lenders, the full amount of any Commitment Fee then accrued on the amount
of the reduction, together with any breakage costs incurred by any of the
Lenders as a result of such reduction. In the event the Borrowers reduce or
terminate, in whole or in part, the Total Commitment on or before the first
anniversary of the Closing Date, the Borrowers shall pay to the Administrative
Agent, for the respective accounts of the Lenders, a yield maintenance fee as
liquidated damages, and not as a penalty, equal to one percent (1.0%) of the
amount of such reduction in, or termination of, the Total Commitment. No
reduction or termination of the Commitments may be reinstated.

     2.4. The Revolving Credit Notes. The Revolving Credit Loans shall be
          --------------------------

One Revolving Credit Note shall be payable to the order of each Lender in a
principal amount equal to such Lender's Commitment or, if less, the outstanding
amount of all Revolving Credit Loans made by such Lender, plus interest accrued
thereon, as set forth below. The Borrowers irrevocably authorize each Lender 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 Lender's Revolving Credit Note, an appropriate notation on such Lender's
Revolving Credit Note Record reflecting the making of such Revolving Credit Loan
or (as the case may be) the receipt of such payment. The outstanding amount of
the Revolving Credit Loans set forth on such Lender's Revolving Credit Note
Record shall be prima facie evidence of the principal amount thereof owing and
                ----- -----
unpaid to such Lender, but the failure to record, or any error in so recording,
any such amount on such Lender's Revolving Credit Note Record shall not limit or
otherwise affect the obligations of the Borrowers hereunder or under any
Revolving Credit Note to make payments of principal of or interest on any
Revolving Credit Note when due.

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

     time.

          (b) Each Revolving Credit Loan which is a LIBOR Rate Loan shall bear
     interest for the period commencing with the Drawdown Date thereof and
     ending on the last day of the Interest Period with respect thereto at the
     rate per annum equal to the LIBOR Rate determined for such Interest Period
     plus the Applicable Margin with respect to LIBOR Rate Loans as in effect
     ----
     from time to time.

The Borrowers jointly and severally promise to pay interest on each Revolving
Credit Loan in arrears on each Interest Payment Date with respect thereto.

     confirmed in a writing in the form of Exhibit C hereto) of each Revolving

     the Borrowers and shall obligate the Borrowers to accept the Revolving
     Credit Loan requested from the Lenders on the proposed Drawdown Date. Each
     Loan Request shall be in a minimum aggregate amount of $1,000,000 and shall
     be in integral multiples of $100,000 in excess thereof.

          2.6.2. Swing Line. Notwithstanding the notice and minimum amount

     requested

<PAGE>

                                      -33-

     by the Borrowers; provided, however, that in no event shall such Revolving
                       --------  -------

     Credit Loans made pursuant to this Section 2.6.2 exceed an aggregate
     principal amount of $10,000,000 at any one time. The Borrowers hereby
     request and authorize the Administrative Agent to make from time to time
     such Revolving Credit Loans by means of appropriate entries of such credits
     sufficient to cover checks and other charges then presented for payment
     from the Operating Account or as otherwise so requested. The Borrowers
     acknowledge and agree that the making of such Revolving Credit Loans shall,
     in each case, be subject in all respects to the provisions of this Credit
     Agreement as if they were Revolving Credit Loans covered by a Loan Request
     including, without limitation, the limitations set forth in Section 2.1 and
     the requirements that the applicable provisions of Section 11 (in the case
     of Revolving Credit Loans made on the Closing Date) and Section 12 be
     satisfied. All actions taken by the Administrative Agent pursuant to the
     provisions of this Section 2.6.2 shall be conclusive and binding on the
     Borrowers and the Lenders absent the Administrative Agent's gross
     negligence or willful misconduct. Revolving Credit Loans made pursuant to
     this Section 2.6.2 shall be Base Rate Loans until converted in accordance
     with the provisions of the Credit Agreement and, prior to a Settlement,
     such interest shall be for the account of the Administrative Agent.

     2.7. Conversion Options.
          ------------------

          2.7.1. Conversion to Different Type of Revolving Credit Loan. The
                 -----------------------------------------------------
     Borrowers may elect from time to time to convert any outstanding Revolving
     Credit Loan to a Revolving Credit Loan of another Type, provided that (a)
                                                             --------
     with respect to any such conversion of a LIBOR Rate Loan to a Base Rate
     Loan, the Borrowers shall give the Administrative Agent at least three (3)
     Business Days prior written notice of such election; (b) with respect to
     any such conversion of a Base Rate Loan to a LIBOR Rate Loan, the Borrowers
     shall give the Administrative Agent at least four (4) LIBOR Business Days
     prior written notice of such election; (c) with respect to any such
     conversion of a LIBOR Rate Loan into a Base Rate Loan, such conversion
     shall only be made on the last day of the Interest Period with respect
     thereto and (d) no Revolving Credit Loan may be converted into a LIBOR 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 Lender shall take
     such action as is necessary to transfer its Commitment Percentage of such
     Revolving Credit Loans to its Domestic Lending Office or its LIBOR Lending
     Office, as the case may be. All or any part of outstanding Revolving Credit
     Loans of any Type

<PAGE>

                                      -34-

     may be converted into a Revolving Credit Loan of another Type as provided
     herein, provided that any partial conversion shall be in an aggregate
             --------
     principal amount of $1,000,000 or a whole multiple thereof. Each Conversion
     Request relating to the conversion of a Revolving Credit Loan to a LIBOR
     Rate Loan shall be irrevocable by the Borrowers.

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

          2.7.3. LIBOR Rate Loans. Any conversion to or from LIBOR 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 LIBOR
     Rate Loans having the same Interest Period shall not be less than
     $1,000,000 and shall be in integral multiples of $100,000 in excess
     thereof. No more than five (5) LIBOR Rate Loans having different Interest
     Periods may be outstanding at any time.

     2.8. Funds for Revolving Credit Loan.
          -------------------------------

          2.8.1. Funding Procedures. Not later than 12:00 noon (Boston time) on
                 ------------------
     the proposed Drawdown Date of any Revolving Credit Loans, each of the
     Lenders will make available to the Administrative Agent, at the
     Administrative Agent's Office, in immediately available funds, the amount
     of such Lender's Commitment Percentage of the amount of the requested
     Revolving Credit Loans. Upon receipt from each Lender of such amount, and
     upon receipt of the documents required by Sections 11 and 12 and the
     satisfaction of the other conditions set forth therein, to the extent
     applicable, the Administrative Agent will make available to

<PAGE>

                                      -35-

     the Borrowers the aggregate amount of such Revolving Credit Loans made
     available to the Administrative Agent by the Lenders. The failure or
     refusal of any Lender to make available to the Administrative 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 Lender from its several obligation hereunder to make available to the
     Administrative Agent the amount of such other Lender's Commitment
     Percentage of any requested Revolving Credit Loans.

          2.8.2. Advances by Administrative Agent. The Administrative Agent may,
                 --------------------------------
     unless notified to the contrary by any Lender prior to a Drawdown Date,
     assume that such Lender has made available to the Administrative Agent on
     such Drawdown Date the amount of such Lender's Commitment Percentage of the
     Revolving Credit Loans to be made on such Drawdown Date, and the
     Administrative Agent may (but it shall not be required to), in reliance
     upon such assumption, make available to the Borrowers a corresponding
     amount. If any Lender makes available to the Administrative Agent such
     amount on a date after such Drawdown Date, such Lender shall pay to the
     Administrative Agent on demand an amount equal to the product of (a) the
     average computed for the period referred to in clause (c) below, of the
     weighted average interest rate paid by the Administrative Agent for federal
     funds acquired by the Administrative Agent during each day included in such
     period, times (b) the amount of such Lender's Commitment Percentage of such
             -----
     Revolving Credit Loans, times (c) 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 Lender's Commitment Percentage of such
     Revolving Credit Loans shall become immediately available to the
     Administrative Agent, and the denominator of which is 360. A statement of
     the Administrative Agent submitted to such Lender with respect to any
     amounts owing under this paragraph shall be prima facie evidence of the
                                                 ----- -----
     amount due and owing to the Administrative Agent by such Lender. If the
     amount of such Lender's Commitment Percentage of such Revolving Credit
     Loans is not made available to the Administrative Agent by such Lender
     within three (3) Business Days following such Drawdown Date, the
     Administrative Agent shall be entitled to recover such amount from the
     Borrowers on demand, with interest thereon at the rate per annum applicable
     to the Revolving Credit 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

<PAGE>

                                      -36-

to Section 8.4(f)) by the Administrative Agent by reference to the Borrowing
Base Report, commercial finance and collateral audit reports, and the appraisals
of Borrowing Base Equipment delivered to the Lenders and the Administrative
Agent pursuant to Section 8.4(h) and other information obtained by or provided
to the Administrative Agent. The Administrative Agent shall give to the
Borrowers written notice of any change in the Borrowing Base determined by the
Administrative Agent resulting from a change in the Determined Value of
Borrowing Base Equipment based upon the results of any such appraisal or
reappraisal, and such notice shall be effective on receipt by the Borrowers.

     2.10. Settlements.
           -----------

          2.10.1. General. On each Settlement Date, the Administrative Agent
                  -------
     shall, not later than 11:00 a.m. (Boston time), give telephonic or
     facsimile notice (a) to the Lenders and the Borrowers of the respective
     outstanding amount of Revolving Credit Loans made by the Administrative
     Agent on behalf of the Lenders from the immediately preceding Settlement
     Date through the close of business on the prior day and the amount of any
     LIBOR Rate Loans to be made (following the giving of notice pursuant to
     Section 2.6.1(b)) on such date pursuant to a Loan Request and (b) to the
     Lenders of the amount (a "Settlement Amount") that each Lender (a "Settling
                               ---------- ------                        --------
     Lender") shall pay to effect a Settlement of any Revolving Credit Loan. A
     ------
     statement of the Administrative Agent submitted to the Lenders and the
     Borrowers or to the Lenders with respect to any amounts owing under this
     Section 2.10 shall be prima facie evidence of the amount due and owing.
                           ----- -----
     Each Settling Lender shall, not later than 3:00 p.m. (Boston time) on such
     Settlement Date, effect a wire transfer of immediately available funds to
     the Administrative Agent in the amount of the Settlement Amount for such
     Settling Lender. All funds advanced by any Lender as a Settling Lender
     pursuant to this Section 2.10 shall for all purposes be treated as a
     Revolving Credit Loan made by such Settling Lender to the Borrower and all
     funds received by any Lender pursuant to this Section 2.10 shall for all
     purposes be treated as repayment of amounts owed with respect to Revolving
     Credit Loans made by such Lender. In the event that any bankruptcy,
     reorganization, liquidation, receivership or similar cases or proceedings
     in which any Borrower is a debtor prevent a Settling Lender from making any
     Revolving Credit Loan to effect a Settlement as contemplated hereby, such
     Settling Lender will make such dispositions and arrangements with the other
     Lenders with respect to such Revolving Credit Loans, either by way of
     purchase of participations, distribution, pro tanto assignment of claims,
                                               --- -----
     subrogation or otherwise as shall result in each Lender's share of the
     outstanding Revolving Credit Loans being equal, as nearly as may be,

<PAGE>

                                      -37-

     to such Lender's Commitment Percentage of the outstanding amount of the
     Revolving Credit Loans.

          2.10.2. Failure to Make Funds Available. The Administrative Agent may,
                  -------------------------------
     unless notified to the contrary by any Settling Lender prior to a
     Settlement Date, assume that such Settling Lender has made or will make
     available to the Administrative Agent on such Settlement Date the amount of
     such Settling Lender's Settlement Amount, and the Administrative Agent may
     (but it shall not be required to), in reliance upon such assumption, make
     available to the Borrowers a corresponding amount. If any Settling Lender
     makes available to the Administrative Agent such amount on a date after
     such Settlement Date, such Settling Lender shall pay to the Administrative
     Agent on demand an amount equal to the product of (a) the average computed
     for the period referred to in clause (c) below, of the weighted average
     interest rate paid by the Administrative Agent for federal funds acquired
     by the Administrative Agent during each day included in such period, times
     (b) the amount of such Settlement Amount, times (c) a fraction, the
     numerator of which is the number of days that elapse from and including
     such Settlement Date to the date on which the amount of such Settlement
     Amount shall become immediately available to the Administrative Agent, and
     the denominator of which is 360. A statement of the Administrative Agent
     submitted to such Settling Lender with respect to any amounts owing under
     this Section 2.10.2 shall be prima facie evidence of the amount due and
     owing to the Administrative Agent by such Settling Lender. If such Settling
     Lender's Settlement Amount is not made available to the Administrative
     Agent by such Settling Lender within three (3) Business Days following such
     Settlement Date, the Administrative Agent shall be entitled to recover such
     amount from the Borrowers on demand, with interest thereon at the rate per
     annum applicable to the Revolving Credit Loans as of such Settlement Date.

          2.10.3. No Effect on Other Lenders. The failure or refusal of any
                  --------------------------
     Settling Lender to make available to the Administrative Agent at the
     aforesaid time and place on any Settlement Date the amount of such Settling
     Lender's Settlement Amount shall not (a) relieve any other Settling Lender
     from its several obligations hereunder to make available to the
     Administrative Agent the amount of such other Settling Lender's Settlement
     Amount or (b) impose upon any Lender, other than the Settling Lender so
     failing or refusing, any liability with respect to such failure or refusal
     or otherwise increase the Commitment of such other Lender.

     2.11. Repayments of Revolving Credit Loans Prior to Event of Default.
           --------------------------------------------------------------

          2.11.1. Credit for Funds Received in Concentration Account. Prior to
                  --------------------------------------------------
     the occurrence of an Event of Default as to which the account officers of
     the Administrative Agent active upon the Borrowers' account have actual
     knowledge, (a) all funds and cash proceeds in the form of money, checks and
     like items received in the Fleet Concentration Account as contemplated by
     Section 8.13 shall be credited, on the same Business Day on which the
     Administrative Agent determines that good collected funds have been
     received, and, prior to the receipt of good collected funds, on a
     provisional basis until final receipt of good collected funds, and applied
     as contemplated by Section 2.11.2, (b) all funds and cash proceeds in the
     form of a wire transfer received in the Fleet Concentration Account as
     contemplated by Section 8.13 shall be credited on the same Business Day as
     the Administrative Agent's receipt of such amounts (or up to such later
     date as the Administrative Agent determines that good collected funds have
     been received), and applied as contemplated by Section 2.11.2, and (c) all
     funds and cash proceeds in the form of an automated clearing house transfer
     received in the Fleet Concentration Account as contemplated by Section 8.13
     shall be credited, on the next Business Day following the Administrative
     Agent's receipt of such amounts (or up to such later date as the
     Administrative Agent determines that good collected funds have been
     received), and applied as contemplated by Section 2.11.2. For purposes of
     the foregoing provisions of this Section 2.11.1, the Administrative Agent
     shall not be deemed to have received any such funds or cash proceeds on any
     day unless received by the Administrative Agent before 2:30 p.m. (Boston
     time) on such day. The Borrowers further acknowledge and agree that any
     such provisional credits or credits in respect of wire or automatic
     clearing house funds transfers shall be subject to reversal if final
     collection in good funds of the related item is not received by, or final
     settlement of the funds transfer is not made in favor of, the
     Administrative Agent in accordance with the Administrative Agent's
     customary procedures and practices for collecting provisional items or
     receiving settlement of funds transfers.

          2.11.2. Application of Payments Prior to Event of Default.
                  -------------------------------------------------

               (a) Prior to the occurrence of an Event of Default of which the
          account officers of the Administrative Agent active on the Borrowers'
          account have knowledge, all funds transferred to the Fleet
          Concentration Account and for which the Borrowers

<PAGE>

                                      -39-

          have received credits shall be applied to the Obligations as follows:

                    (i) first, to pay amounts then due and payable under this
               Agreement, the Notes and the other Loan Documents;

                    (ii) second, to reduce Revolving Credit Loans made by the
               Administrative Agent pursuant to Section 2.6.2 and for which
               Settlement has not then been made;

                    (iii) third, to reduce other Revolving Credit Loans which
               are Base Rate Loans;

                    (iv) fourth, to reduce Revolving Credit Loans which are
               LIBOR Rate Loans; and

                    (v) fifth, except as otherwise required by Section 4.2(b)
               and (c), to the Operating Account.

               (b) All prepayments of LIBOR Rate Loans prior to the end of an
          Interest Period shall obligate the Borrowers to pay any breakage costs
          associated with such LIBOR Rate Loans in accordance with Section 5.10.
          Prior to the occurrence of an Event of Default, the Borrower may elect
          to avoid such breakage costs by providing to the Administrative Agent
          cash in an amount sufficient to cash collateralize such LIBOR Rate
          Loans, but in no event shall the Borrowers be deemed to have paid such
          LIBOR Rate Loans until such cash has been paid to the Administrative
          Agent for application to such LIBOR Rate Loans. The Administrative
          Agent may elect to cause such cash collateral to be deposited into
          either (i) a cash collateral account pursuant to the terms of a cash
          collateral agreement executed by the Borrowers and the Administrative
          Agent and in form and substance satisfactory to the Administrative
          Agent or (ii) the Borrowers' Operating Account with appropriate
          instructions prohibiting the Borrowers' withdrawal of such funds so
          long as they remain cash collateral. In each such case, the Borrowers
          agree to execute and deliver to the Administrative Agent such
          instruments and documents, including Uniform Commercial Code financing
          statements and agreements with any third party depository banks, as
          the Administrative Agent may request.

                                      -40-

               (c) All prepayments of the Revolving Credit Loans pursuant to
          this Section 2.11.2 shall be allocated among the Lenders making such
          Revolving Credit Loans, in proportion, as nearly as practicable, to
          the respective unpaid principal amount of such Revolving Credit Loans
          outstanding, with adjustments to the extent practicable to equalize
          any prior payments or repayments not exactly in proportion. Prior to
          any Settlement Date, however, all prepayments of the Revolving Credit
          Loans shall be applied in accordance with this Section 2.11.2, first
          to outstanding Revolving Credit Loans of the Administrative Agent.

     2.12. Repayments of Revolving Credit Loans After Event of Default.
           -----------------------------------------------------------
Following the occurrence and during the continuance of an Event of Default of
which the account officers of the Administrative Agent active on the Borrowers'
account have knowledge, all funds transferred to the Fleet Concentration Account
and for which the Borrowers have received credits shall be applied to the
Obligations in accordance with Section 13.4.

                   3. REPAYMENT OF THE REVOLVING CREDIT LOANS.
                      ---------------------------------------

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

     3.2. Mandatory Repayments of Revolving Credit Loans.
          ----------------------------------------------

          3.2.1. Facility. 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 (a) the Total Commitment at
     such time and (b) the Borrowing Base at such time, then the Borrowers shall
     immediately pay the amount of such excess to the Administrative Agent for
     the respective accounts of the Lenders for application: first, to any
     Unpaid Reimbursement Obligations; second, to the Revolving Credit Loans;
     and third, to provide to the Administrative Agent cash collateral for
     Reimbursement Obligations as contemplated by Section 4.2(b) and (c). Each
     payment of any Unpaid Reimbursement Obligations or prepayment of Revolving
     Credit Loans shall be allocated among the Lenders, in proportion, as nearly
     as practicable, to each Reimbursement Obligation or (as the case may be)
     the respective unpaid principal amount of each Lender's Revolving Credit
     Note, with adjustments to the extent practicable to equalize any prior
     payments or repayments not exactly in proportion.

                                      -41-

          3.2.2. Asset Sales. In the event that any of the Borrowers or any of
                 -----------
     their Subsidiaries shall sell any of their assets or group of related
     assets pursuant to an Asset Sale, whether by sale of assets or stock, where
     such Asset Sale is either permitted pursuant to Section 9.5.2 or is
     previously consented to in writing by the Administrative Agent, then,
     immediately upon the receipt thereof, the Borrowers shall repay the
     Obligations in an amount equal to one hundred percent (100%) of the amount
     of the Net Cash Sale Proceeds of such asset sale (after taxes calculated at
     the effective book tax rate in accordance with GAAP).

          3.2.3. Debt and Equity Issuances. In the event that any of the
                 -------------------------
     Borrowers or any of their Subsidiaries shall issue new debt or sell or
     issue any shares of their stock, options or warrants for the purchase of
     its stock or other equity or equity instruments (other than (i) stock,
     warrants and options awarded to employees and directors pursuant to
     incentive compensation plans or other Employee Benefit Plans operated by
     such Persons and (ii) equity and equity instruments issued by any Borrower
     or any Subsidiary to finance any acquisition previously consented to in
     writing by the Administrative Agent or otherwise permitted pursuant to
     Section 9.5), then, immediately upon the receipt thereof, the Borrowers
     shall, or shall cause such Subsidiary to, repay the Obligations in an
     amount equal to one hundred percent (100%) of (i) the Net Cash Proceeds of
     such issuance of new debt or (ii) the Net Cash Equity Issuance Proceeds of
     sale or issuance of new equity (as the case may be), such repayment of the
     Obligations to be in the manner set forth in Section 3.2.1.

     3.3. Optional Repayments of Revolving Credit Loans. The Borrowers shall
          ---------------------------------------------
have the right, at their election, to repay the outstanding amount of the
Revolving Credit Loans, as a whole or in part, at any time without penalty or
premium, provided that any full or partial prepayment of the outstanding amount
         --------
of any LIBOR Rate Loans pursuant to this Section 3.3 may be made only on the
last day of the Interest Period relating thereto. The Borrowers shall give the
Administrative Agent, no later than 10:00 a.m., Boston time, at least one (1)
Business Days prior written notice of any proposed prepayment pursuant to this
Section 3.3 of Base Rate Loans, and three (3) LIBOR Business Days notice of any
proposed prepayment pursuant to this Section 3.3 of LIBOR Rate Loans, in each
case specifying the proposed date of prepayment of Revolving Credit Loans and
the principal amount to be prepaid. Each such partial prepayment of the
Revolving Credit Loans shall be in a minimum aggregate amount of $200,000 and
shall be in integral multiples of $50,000 in excess thereof, shall be
accompanied by the payment of accrued interest on the principal prepaid to the
date of prepayment and shall be applied, in the absence of instruction by the
Borrowers, first to the

<PAGE>

                                      -42-

principal of Base Rate Loans and then to the principal of LIBOR Rate Loans. Each
partial prepayment shall be allocated among the Lenders, in proportion, as
nearly as practicable, to the respective unpaid principal amount of each
Lender's Revolving Credit Note, with adjustments to the extent practicable to
equalize any prior repayments not exactly in proportion.

                              4. LETTERS OF CREDIT.
                                 -----------------

     4.1. Letter of Credit Commitments.

          4.1.1. Commitment to Issue Letters of Credit. Subject to the terms and
                 -------------------------------------
     conditions hereof and the execution and delivery by any Borrower of a
     letter of credit application on the Issuing Bank's customary form (a
     "Letter of Credit Application"), the Administrative Agent on behalf of the
      ------ -- ------ -----------
     Lenders and in reliance upon the agreement of the Lenders set forth in
     Section 4.1.4 and upon the representations and warranties of the Borrowers
     contained herein, agrees to (i) cause the Issuing Bank to issue, extend and
     renew for the account of the Borrowers and/or their Subsidiaries one or
     more standby or documentary letters of credit (individually, a "Letter of
                                                                     ------ --
     Credit"), in such form as may be requested from time to time by any
     ------
     Borrower and agreed to by the Administrative Agent and the Issuing Bank and
     (ii) execute a Letter of Credit Guaranty to support the reimbursement
     obligations of the Borrowers with respect to the Letters of Credit;
     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 $30,000,000 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 Revolving Credit
     Loans outstanding shall not exceed the lesser of (A) the Total Commitment
     at such time and (B) the Borrowing Base at such time. Any amounts paid by
     the Issuing Bank under any Letter of Credit and any amounts paid by the
     Administrative Agent under any Letter of Credit Guaranty shall be treated
     as Revolving Credit Loans, shall be secured by all of the Collateral and
     shall bear interest and be payable at the same rate and in the same manner
     as Revolving Credit Loans. Notwithstanding the foregoing, the
     Administrative Agent shall have no obligation to cause the Issuing Bank to
     issue any Letter of Credit to support or secure any Indebtedness of the
     Borrowers or any of their Subsidiaries to the extent that such Indebtedness
     was incurred prior to the proposed issuance date of such Letter of Credit,
     unless in any such case the Borrowers demonstrate to the satisfaction of
     the Administrative Agent that (x) such prior incurred Indebtedness were
     then fully secured by a

     any Borrower or any Subsidiary to the proposed beneficiary of such Letter
     of Credit or (y) such prior incurred Indebtedness were then secured or
     supported by a letter of credit issued for the account of any such Borrower
     or any such Subsidiary and the reimbursement obligation with respect to
     such letter of credit was fully secured by a prior perfected and
     unavoidable security interest in collateral provided to the issuer of such
     letter of credit by any such Borrower or any such Subsidiary.

          4.1.2. Letter of Credit Applications. Each Letter of Credit
                 -----------------------------
     Application shall be completed to the satisfaction of the Administrative
     Agent and the Issuing Bank. 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.

          4.1.3. Terms of Letters of Credit. Each Letter of Credit issued,
                 --------------------------
     amended, extended or renewed hereunder shall, among other things, (a)
     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 (b) have an expiry date no later than the date which
     is fourteen (14) days (or, if the Letter of Credit is confirmed by a
     confirmer or otherwise provides for one or more nominated persons,
     forty-five (45) days) prior to the Maturity Date. Each Letter of Credit so
     issued, amended, extended or renewed shall be subject to the Uniform
     Customs and Practice for Documentary Credits (1993 Revision), International
     Chamber of Commerce Publication No. 500 or any successor version thereto
     adopted by the Administrative Agent or the Issuing Bank (as the case may
     be) in the ordinary course of their respective businesses as letter of
     credit issuers and in effect at the time of issuance of such Letter of
     Credit (the "Uniform Customs") or, in the case of a standby Letter of
                  ------- -------
     Credit, either the Uniform Customs or the International Standby Practices
     (ISP98), International Chamber of Commerce Publication No. 590, or any
     successor code of standby letter of credit practices among banks adopted by
     the Administrative Agent or the Issuing Bank (as the case may be) in the
     ordinary course of their respective businesses as a standby letter of
     credit issuers and in effect at the time of issuance of such Letter of
     Credit.

          4.1.4. Reimbursement Obligations of Lenders. Each Lender severally
                 ------------------------------------
     agrees that it shall be absolutely liable, without regard to the occurrence
     of any Default or Event of Default or any

<PAGE>

                                      -44-

     other condition precedent whatsoever, to the extent of such Lender's
     Commitment Percentage, to reimburse the Administrative Agent on demand for
     the amount of each draft paid by the Issuing Bank under each Letter of
     Credit and each payment made by the Administrative Agent to the Issuing
     Bank under the Letter of Credit Guaranty to the extent that such amount is
     not reimbursed by the Borrowers pursuant to Section 4.2 (such agreement for
     a Lender being called herein the "Letter of Credit Participation" of such
                                       ------ -- ------ -------------
     Lender).

          4.1.5. Participations of Lenders. Each such payment made by a Lender
                 -------------------------
     shall be treated as the purchase by such Lender of a participating interest
     in the Borrowers' Reimbursement Obligation under Section 4.2 in an amount
     equal to such payment. Each Lender shall share in accordance with its
     participating interest in any interest which accrues pursuant to
     Section 4.2.

     4.2. Reimbursement Obligation of the Borrowers. In order to induce the
          -----------------------------------------
Administrative Agent to cause the Issuing Bank to issue, amend, extend and renew
each Letter of Credit and the Lenders to participate therein, the Borrowers
hereby jointly and severally agree to reimburse or pay to the Administrative
Agent, for the account of the Administrative Agent and/or the Issuing Bank or
(as the case may be) the Lenders, with respect to each Letter of Credit issued,
amended, extended or renewed by the Issuing Bank hereunder,

          (a) except as otherwise expressly provided in Section 4.2(b) and (c),
     on each date that any draft presented under such Letter of Credit is
     honored by the Issuing Bank, or the Administrative Agent or the Issuing
     Bank otherwise makes a payment with respect thereto or the Administrative
     Agent makes any payment under a Letter of Credit Guaranty, (i) the amount
     paid by the Administrative Agent or the Issuing Bank (as the case may be)
     under or with respect to such Letter of Credit, and (ii) the amount of any
     taxes, fees, charges or other costs and expenses whatsoever incurred by the
     Administrative Agent, the Issuing Bank or any Lender in connection with any
     payment made by the Administrative Agent, the Issuing Bank or any Lender
     under, or with respect 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 Administrative Agent for the
     benefit of the Lenders and the Administrative Agent as cash collateral for
     all Reimbursement Obligations, and

<PAGE>

                                      -45-

          (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 Section 13, an amount equal to the then Maximum Drawing
     Amount on all Letters of Credit, which amount shall be held by the
     Administrative Agent for the benefit of the Lenders and the Administrative
     Agent as cash collateral for all Reimbursement Obligations.

Each such payment shall be made to the Administrative Agent at the
Administrative Agent's Office in immediately available funds. Interest on any
and all amounts remaining unpaid by the Borrowers under this Section 4.2 at any
time from the date such amounts become due and payable (whether as stated in
this Section 4.2, by acceleration or otherwise) until payment in full (whether
before or after judgment) shall be payable to the Administrative Agent on demand
at the rate specified in Section 5.11 for overdue principal on the Revolving
Credit Loans.

     4.3. Letter of Credit Payments. If any draft shall be presented or other
          -------------------------
demand for payment shall be made under any Letter of Credit, the Administrative
Agent shall notify the Borrowers 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 Borrowers fail to reimburse the
Administrative Agent as provided in Section 4.2 on or before the date that such
draft is paid or other payment is made by the Administrative Agent or the
Issuing Bank, the Administrative Agent may at any time thereafter notify the
Lenders 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 Lender shall make available to the Administrative Agent, at the
Administrative Agent's Office, in immediately available funds, such Lender's
Commitment Percentage of such Unpaid Reimbursement Obligation, together with an
amount equal to the product of (a) the average, computed for the period referred
to in clause (c) below, of the weighted average interest rate paid by the
Administrative Agent for federal funds acquired by the Administrative Agent
during each day included in such period, times (b) the amount equal to such
                                         -----
Lender's Commitment Percentage of such Unpaid Reimbursement Obligation, times
                                                                        -----
(c) a fraction, the numerator of which is the number of days that elapse from
and including the date the Administrative Agent or the Issuing Bank paid the
draft presented for honor or otherwise made payment to the date on which such
Lender's Commitment Percentage of such Unpaid Reimbursement Obligation shall
become immediately available to the Administrative Agent, and the denominator of
which is 360. The responsibility of the Administrative Agent and the Issuing
Bank to the Borrowers and the Lenders shall be only to determine that the
documents

<PAGE>

                                      -46-

(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.

     4.4. Obligations Absolute. The Borrowers' obligations under this Section 4
          --------------------
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 any Borrower may have or have had against the Administrative Agent, the
Issuing Bank, any Lender or any beneficiary of a Letter of Credit. The Borrowers
further agree with the Administrative Agent and the Lenders that the
Administrative Agent, the Issuing Bank and the Lenders shall not be responsible
for, and the Borrowers' Reimbursement Obligations under Section 4.2 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 any 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 any Borrower against the beneficiary of any
Letter of Credit or any such transferee. The Administrative Agent, the Issuing
Bank and the Lenders 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 Borrowers agree that
any action taken or omitted by the Administrative Agent, the Issuing Bank or any
Lender 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 Borrowers and
shall not result in any liability on the part of the Administrative Agent, the
Issuing Bank or any Lender to the Borrowers.

     4.5. Reliance by Issuer. To the extent not inconsistent with Section 4.4,
          ------------------
the Administrative Agent and the Issuing Bank 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
Administrative Agent or the Issuing Bank. The Administrative Agent and the
Issuing Bank shall be fully justified in failing or refusing to take any action
under this Credit Agreement unless it shall first have received such advice or
concurrence of the Required Lenders as it reasonably deems appropriate or it
shall first be indemnified to its reasonable satisfaction by the Lenders against
any and all liability and expense which may be incurred

<PAGE>

                                      -47-

by it by reason of taking or continuing to take any such action. The
Administrative Agent and the Issuing Bank 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 Required Lenders, and such request and any
action taken or failure to act pursuant thereto shall be binding upon the
Lenders and all future holders of the Revolving Credit Notes or of a Letter of
Credit Participation.

     4.6. Letter of Credit Fee. The Borrowers shall pay, on a monthly basis in
          --------------------
advance, a fee (in each case, a "Letter of Credit Fee") to the Administrative
                                 ------ -- ------ ---
Agent in respect of each standby Letter of Credit and each documentary Letter of
Credit an amount equal to the Applicable Margin per annum then in effect with
respect to Letter of Credit Fees on the available amount of each such Letter of
Credit, which shall be for the accounts of the Lenders in accordance with their
respective Commitment Percentages. In addition, the Borrowers shall pay, on the
date of issuance or any extension or renewal or increase of any Letter of
Credit, a fee to the Administrative Agent in an amount equal to one-eighth of
one percent (0.125%) per annum of the available amount of such standby Letter of
Credit, which shall be for the account of the Administrative Agent, as a
fronting fee. In respect of each Letter of Credit, the Borrowers shall also pay
to the Administrative Agent for the Issuing Bank's or the Administrative Agent's
own account, at such other time or times as such charges are customarily made by
the Administrative Agent or the Issuing Bank, the Administrative Agent's and/or
the Issuing Bank's customary issuance, amendment, negotiation or document
examination and other administrative fees as in effect from time to time.

                         5. CERTAIN GENERAL PROVISIONS.
                            ---------------------------

     5.1. Closing and Arrangement Fees. The Borrowers jointly and severally
          ----------------------------
agree to pay to the Administrative Agent on the Closing Date the fees as set
forth in the Fee Letter.

     5.2. Administrative Agent's Fee. The Borrowers jointly and severally agree
          --------------------------
to pay the Administrative Agent annually in advance, for the Administrative
Agent's own account, on the Closing Date and on each anniversary of the Closing
Date, an Administrative Agent's fee as set forth in the Fee Letter.

     5.3. Funds for Payments.
          ------------------

          5.3.1. Payments to Administrative Agent. All payments of principal,
                 --------------------------------
     interest, Reimbursement Obligations, Fees and any other amounts due
     hereunder or under any of the other Loan Documents

<PAGE>

                                      -48-

     shall be made on the due date thereof to the Administrative Agent in
     Dollars, for the respective accounts of the Lenders and the Administrative
     Agent, at the Administrative Agent's Office or at such other place that the
     Administrative Agent may from time to time designate, in each case at or
     about 11:00 a.m. (Boston, Massachusetts, time or other local time at the
     place of payment) and in immediately available funds.

          5.3.2. No Offset, etc. All payments by the Borrowers hereunder and
                 --------------
     under any of the other Loan Documents shall be made without recoupment,
     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 Borrowers is compelled by
     law to make such deduction or withholding. If any such obligation is
     imposed upon the Borrowers with respect to any amount payable by it
     hereunder or under any of the other Loan Documents, the Borrowers will pay
     to the Administrative Agent, for the account of the Lenders or (as the case
     may be) the Administrative 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 Lenders or the
     Administrative Agent to receive the same net amount which the Lenders or
     the Administrative Agent would have received on such due date had no such
     obligation been imposed upon the Borrowers. The Borrowers will deliver
     promptly to the Administrative Agent certificates or other valid vouchers
     for all taxes or other charges deducted from or paid with respect to
     payments made by the Borrowers hereunder or under such other Loan Document.

     5.4. Computations. All computations of interest on the LIBOR Rate Loans
          ------------
shall be based on a 360-day year and paid for the actual number of days elapsed.
All computations of interest on the Base Rate Loans shall be based on a 365-day
year and paid for the actual number of days elapsed. Except as otherwise
provided in the definition of the term "Interest Period" with respect to LIBOR
                                        -------- ------
Rate Loans, whenever a payment hereunder or under any of the other Loan
Documents becomes due on a day that is not a Business Day, the due date for such
payment shall be extended to the next succeeding Business Day, and interest
shall accrue during such extension. The outstanding amount of the Revolving
Credit Loans as reflected on the Revolving Credit Note Records from time to time
shall be considered correct and binding on the Borrowers unless within five (5)
Business Days after receipt of any notice by the Administrative Agent or any of
the Lenders of

<PAGE>

                                      -49-

such outstanding amount, the Borrowers shall notify the Administrative Agent or
such Lender to the contrary.

     5.5. Inability to Determine LIBOR Rate. In the event, prior to the
          ---------------------------------
commencement of any Interest Period relating to any LIBOR Rate Loan, the
Administrative Agent shall determine or be notified by the Required Lenders that
(a) adequate and reasonable methods do not exist for ascertaining the LIBOR Rate
that would otherwise determine the rate of interest to be applicable to any
LIBOR Rate Loan during any Interest Period or (b) the LIBOR Rate determined or
to be determined for such Interest Period will not adequately and fairly reflect
the cost to the Lenders of making or maintaining their LIBOR Rate Loans during
such period, the Administrative Agent shall forthwith give notice of such
determination (which shall be conclusive and binding on the Borrowers and the
Lenders) to the Borrowers and the Lenders. In such event (i) any Loan Request or
Conversion Request with respect to LIBOR Rate Loans shall be automatically
withdrawn and shall be deemed a request for Base Rate Loans, (ii) each LIBOR
Rate Loan will automatically, on the last day of the then current Interest
Period relating thereto, become a Base Rate Loan, and (iii) the obligations of
the Lenders to make LIBOR Rate Loans shall be suspended until the Administrative
Agent determines that the circumstances giving rise to such suspension no longer
exist, whereupon the Administrative Agent shall so notify the Borrowers and the
Lenders.

     5.6. Illegality. Notwithstanding any other provisions herein, if any
          ----------
present or future law, regulation, treaty or directive or the interpretation or
application thereof shall make it unlawful for any Lender to make or maintain
LIBOR Rate Loans, such Lender shall forthwith give notice of such circumstances
to the Borrowers and the other Lenders and thereupon (a) the commitment of such
Lender to make LIBOR Rate Loans or convert Base Rate Loans to LIBOR Rate Loans
shall forthwith be suspended and (b) such Lender's Revolving Credit Loans then
outstanding as LIBOR Rate Loans, if any, shall be converted automatically to
Base Rate Loans on the last day of each Interest Period applicable to such LIBOR
Rate Loans or within such earlier period as may be required by law. The
Borrowers hereby jointly and severally agree promptly to pay the Administrative
Agent for the account of such Lender, upon demand by such Lender, any additional
amounts necessary to compensate such Lender for any costs incurred by such
Lender in making any conversion in accordance with this Section 5.6, including
any interest or fees payable by such Lender to lenders of funds obtained by it
in order to make or maintain its LIBOR Rate Loans hereunder.

     5.7. Additional Costs, etc. If any present or future applicable law, which
          ---------------------
expression, as used herein, includes statutes, rules and regulations

<PAGE>

                                      -50-

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 Lender or the Administrative Agent by any central bank
or other fiscal, monetary or other authority (whether or not having the force of
law), shall:

          (a) subject any Lender or the Administrative 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 Lender's Commitment or the Revolving Credit Loans (other than
     taxes based upon or measured by the income or profits of such Lender or the
     Administrative Agent), or

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

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

          (d) impose on any Lender or the Administrative Agent any other
     conditions or requirements with respect to this Credit Agreement, the other
     Loan Documents, any Letters of Credit, the Revolving Credit Loans, such
     Lender's Commitment, or any class of loans, letters of credit or
     commitments of which any of the Revolving Credit Loans or such Lender's
     Commitment forms a part, and the result of any of the foregoing is

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

               (ii) to reduce the amount of principal, interest, Reimbursement
          Obligation or other amount payable to such

<PAGE>

                                      -51-

          Lender or the Administrative Agent hereunder on account of such
          Lender's Commitment, any Letter of Credit or any of the Revolving
          Credit Loans, or

               (iii) to require such Lender or the Administrative 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 Lender or the Administrative Agent from the Borrowers
          hereunder,

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

     5.8. Capital Adequacy. If after the date hereof any Lender or the
          ----------------
Administrative Agent determines that (a) 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 Lenders or Lender
holding companies or any change in the interpretation or application thereof by
a Governmental Authority with appropriate jurisdiction, or (b) compliance by
such Lender or the Administrative Agent or any corporation controlling such
Lender or the Administrative Agent with any law, governmental rule, regulation,
policy, guideline or directive (whether or not having the force of law) of any
such entity regarding capital adequacy, has the effect of reducing the return on
such Lender's or the Administrative Agent's commitment with respect to any Loans
to a level below that which such Lender or the Administrative Agent could have
achieved but for such adoption, change or compliance (taking into consideration
such Lender's or the Administrative 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 Lender or (as the case may be) the Administrative
Agent to be material, then such Lender or the Administrative Agent may notify
the Borrowers of such fact. To the extent that the amount of such reduction in
the return on capital is not reflected in the Base Rate or the LIBOR Rate, the
Borrowers agree to pay such Lender or (as the case may be) the Administrative
Agent for the amount of such reduction in the return on capital as and when such
reduction is determined upon presentation by such

<PAGE>

                                      -52-

Lender or (as the case may be) the Administrative Agent of a certificate in
accordance with Section 5.9 hereof. Each Lender shall allocate such cost
increases among its customers in good faith and on an equitable basis.

     5.9. Certificate. A certificate setting forth any additional amounts
          -----------
payable pursuant to Sections 5.7 or 5.8 and a brief explanation of such amounts
which are due, submitted by any Lender or the Administrative Agent to the
Borrowers, shall be conclusive, absent manifest error, that such amounts are due
and owing.

     5.10. Indemnity. The Borrowers jointly and severally agree to indemnify
           ---------
each Lender and to hold each Lender harmless from and against any loss, cost or
expense (including loss of anticipated profits) that such Lender may sustain or
incur as a consequence of (a) default by the Borrowers in payment of the
principal amount of or any interest on any LIBOR Rate Loans as and when due and
payable, including any such loss or expense arising from interest or fees
payable by such Lender to banks of funds obtained by it in order to maintain its
LIBOR Rate Loans, (b) default by the Borrowers in making a borrowing or
conversion after the Borrowers have given (or is deemed to have given) a Loan
Request or a Conversion Request relating thereto in accordance with Section 2.6
or Section 2.7 or (c) the making of any payment of a LIBOR 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 Lender to lenders of funds obtained
by it in order to maintain any such Loans.

     5.11. Interest After Default.
           ----------------------

          5.11.1. Overdue Amounts. Overdue principal and (to the extent
                  ---------------
     permitted by applicable law) interest on the Revolving Credit 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 rate of interest then
     applicable thereto (or, if no rate of interest is then applicable thereto,
     the Base Rate) until such amount shall be paid in full (after as well as
     before judgment).

          5.11.2. Amounts Not Overdue. During the continuance of a Default or an
                  -------------------
     Event of Default the principal of the Revolving Credit Loans not overdue
     shall, until such Default or Event of Default has been cured or remedied or
     such Default or Event of Default has been waived by the Required Lenders
     pursuant to Section 16.12, bear interest at a rate per annum equal to the
     greater of (a) two percent (2%) above the

<PAGE>

                                      -53-

     rate of interest otherwise applicable to such Revolving Credit Loans
     pursuant to Section 2.5 and (b) the rate of interest applicable to overdue
     principal pursuant to Section 5.11.1.

     5.12. Late Fee. If the entire amount of any required principal and/or
           --------
interest payment is not paid in full within ten (10) days after the same is due,
the Borrowers jointly and severally agree to pay the Administrative Agent for
the account of the Lenders a late fee equal to five percent (5%) of the required

     5.13. Concerning Joint and Several Liability of the Borrowers.
           -------------------------------------------------------

          (a) Each Borrower is accepting joint and several liability hereunder
     in consideration of the financial accommodation to be provided by the
     Lenders under this Credit Agreement, for the mutual benefit, directly and
     indirectly, of each Borrower and in consideration of the undertakings of
     each Borrower to accept joint and several liability for the obligations of
     each of them.

          (b) Each Borrower jointly and severally hereby irrevocably and
     unconditionally accepts, not merely as a surety but also as a co-debtor,
     joint and several liability with the other Borrowers with respect to the
     payment and performance of all of the Obligations arising under this Credit
     Agreement, it being the intention of the parties hereto that all the
     Obligations shall be the joint and several obligations of each Borrower
     without preferences or distinction among them.

          (c) If and to the extent that any Borrower shall fail to make any
     payment with respect to any of the obligations hereunder as and when due or
     to perform any of such obligations in accordance with the terms thereof,
     then in each such event, the other Borrowers will make such payment with
     respect to, or perform, such obligation.

          (d) The obligations of each Borrower under the provisions of this
     Section 5.13 constitute full recourse obligations of such Borrower,
     enforceable against it to the full extent of its properties and assets,
     irrespective of the validity, regularity or enforceability of this Credit
     Agreement or any other circumstances whatsoever.

          (e) Except as otherwise expressly provided herein, each Borrower
     hereby waives notice of acceptance of its joint and several liability,
     notice of any and all Revolving Credit Loans made under this

                                      -54-

     Credit Agreement, notice of occurrence of any Event of Default, or of any
     demand for any payment under this Credit Agreement, notice of any action at
     any time taken or omitted by the Lenders under or in respect of any of the
     Obligations hereunder, any requirement of diligence and, generally, all
     demands, notices and other formalities of every kind in connection with
     this Credit Agreement. Each Borrower hereby assents to, and waives notice
     of, any extension or postponement of the time for the payment of any of the
     Obligations hereunder, the acceptance of any partial payment thereon, any
     waiver, consent or other action or acquiescence by the Lenders at any time
     or times in respect of any default by any Borrower in the performance or
     satisfaction of any term, covenant, condition or provision of this Credit
     Agreement, any and all other indulgences whatsoever by the Lenders in
     respect of any of the Obligations hereunder, and the taking, addition,
     substitution or release, in whole or in part, at any time or times, of any
     security for any of such Obligations or the addition, substitution or
     release, in whole or in part, of any Borrower. Without limiting the
     generality of the foregoing, each Borrower assents to any other action or
     delay in acting or failure to act on the part of the Lenders, including,
     without limitation, any failure strictly or diligently to assert any right
     or to pursue any remedy or to comply fully with applicable laws or
     regulations thereunder which might, but for the provisions of this Section
     5.13, afford grounds for terminating, discharging or relieving such
     Borrower, in whole or in part, from any of its obligations under this
     Section 5.13, it being the intention of each Borrower that, so long as any
     of the Obligations hereunder remain unsatisfied, the obligations of such
     Borrower under this Section 5.13 shall not be discharged except by
     performance and then only to the extent of such performance. The
     obligations of each Borrower under this Section 5.13 shall not be
     diminished or rendered unenforceable by any winding up, reorganization,
     arrangement, liquidation, reconstruction or similar proceeding with respect
     to any reconstruction or similar proceeding with respect to any Borrower or
     any Lender. The joint and several liability of the Borrowers hereunder
     shall continue in full force and effect notwithstanding any absorption,
     merger, amalgamation or any other change whatsoever in the name,
     membership, constitution or place of formation of any Borrower or any
     Lender.

          (f) Each Borrower hereby agrees that the payment of any amounts due
     with respect to the indebtedness owing by any Borrower to any other
     Borrower is hereby subordinated to the prior payment in full in cash of the
     Obligations. Each Borrower hereby agrees that after the occurrences and
     during the continuance of any Default or Event of

<PAGE>

                                      -55-

     Default, such Borrower will not demand, sue for or otherwise attempt to
     collect any indebtedness of any other Borrower owing to such Borrower until
     the Obligations shall have been paid in full in cash. If, notwithstanding
     the foregoing sentence, such Borrower shall collect, enforce or receive any
     amounts in respect of such indebtedness, such amounts shall be collected,
     enforced, received by such Borrower as trustee for the Administrative Agent
     and be paid over to the Administrative Agent for the pro rata accounts of
                                                          --- ----
     the Lenders to be applied to repay the Obligations.

          (g) The provisions of this Section 5.13 are made for the benefit of
     the Lenders and their successors and assigns, and may be enforced in good
     faith by them from time to time against any or all of the Borrowers as
     often as the occasion therefor may arise and without requirement on the
     part of the Lenders first to marshal any of their claims or to exercise any
     of their rights against any other Borrower or to exhaust any remedies
     available to them against any other Borrower or to resort to any other
     source or means of obtaining payment of any of the Obligations hereunder or
     to elect any other remedy. The provisions of this Section 5.13 shall remain
     in effect until all of the Obligations shall have been paid in full or
     otherwise fully satisfied. If at any time, any payment, or any part
     thereof, made in respect of any of the Obligations, is rescinded or must
     otherwise be restored or returned by the Lenders upon the insolvency,
     bankruptcy or reorganization of any of the Borrowers, or otherwise, the
     provisions of this Section 5.13 will forthwith be reinstated in effect, as
     though such payment had not been made.

director or such employee or, to the knowledge of the Borrowers, any
corporation, partnership, trust or other entity in which any officer, director,
or any such employee has a substantial interest or is an officer, director,
trustee or partner.

     7.16. Employee Benefit Plans.
           ----------------------

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

          7.16.2. Terminability of Welfare Plans. No Employee Benefit Plan,
                  ------------------------------
     which is an employee welfare benefit plan within the meaning of Section

     termination of employment, except as required by Title I, Part 6 of ERISA
     or the applicable state insurance laws. Each Borrower may terminate each
     such Plan at any time (or at any time subsequent to the expiration of any
     applicable bargaining agreement) in the

<PAGE>

                                      -61-

     discretion of each Borrower without liability to any Person other than for
     claims arising prior to termination.

          7.16.3. Guaranteed Pension Plans. Each contribution required to be
                  ------------------------
     made to a Guaranteed Pension Plan, whether required to be made to avoid the
     incurrence of an accumulated funding deficiency, the notice or lien
     provisions of Section 302(f) of ERISA, or otherwise, has been timely made.
     No waiver of an accumulated funding deficiency or extension of amortization
     periods has been received with respect to any Guaranteed Pension Plan, and
     no Borrower nor any ERISA Affiliate is obligated to or has posted security
     in connection with an amendment to a Guaranteed Pension Plan pursuant to
     Section 307 of ERISA or Section 401(a)(29) of the Code. No liability to the
     PBGC (other than required insurance premiums, all of which have been paid)
     has been incurred by any Borrower or any ERISA Affiliate with respect to
     any Guaranteed Pension Plan and there has not been any ERISA Reportable
     Event (other than an ERISA Reportable Event as to which the requirement of
     30 days notice has been waived), or any other event or condition which
     presents a material risk of termination of any Guaranteed Pension Plan by
     the PBGC. Based on the latest valuation of each Guaranteed Pension Plan
     (which in each case occurred within twelve months of the date of this
     representation), and on the actuarial methods and assumptions employed for
     that valuation, the aggregate benefit liabilities of all such Guaranteed
     Pension Plans within the meaning of Section 4001 of ERISA did not exceed
     the aggregate value of the assets of all such Guaranteed Pension Plans,
     disregarding for this purpose the benefit liabilities and assets of any
     Guaranteed Pension Plan with assets in excess of benefit liabilities.

          7.16.4. Multiemployer Plans. No Borrower nor any ERISA Affiliate has
                  -------------------

     such Multiemployer Plan under Section 4201 of ERISA or as a result of a
     sale of assets described in Section 4204 of ERISA. No Borrower nor any
     ERISA Affiliate has been notified that any Multiemployer Plan is in
     reorganization or insolvent under and within the meaning of Section 4241 or
     Section 4245 of ERISA or is at risk of entering reorganization or becoming
     insolvent, or that any Multiemployer Plan intends to terminate or has been
     terminated under Section 4041A of ERISA.

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

          (p) a Change of Control shall occur;

then, and in any such event, so long as the same may be continuing, the
Administrative Agent may, and upon the request of the Required Lenders shall, by
notice in writing to the Borrowers declare all amounts owing with respect to
this Credit Agreement, the Revolving Credit Notes and the other Loan Documents
and all Reimbursement Obligations to be, and they shall thereupon forthwith
become, immediately due and payable without presentment, demand, protest or
other notice of any kind, all of which are hereby expressly waived by the
Borrowers; provided that in the event of any Event of Default specified in
           --------
Sections 13.1(g), 13.1(h) or 13.1(j), all such amounts shall become immediately
due and payable automatically and without any requirement of notice from the
Administrative Agent or any Lender.

                                      -92-

     13.2. Termination of Commitments. If any one or more of the Events of
           --------------------------
Default specified in Section 13.1(g), Section 13.1(h) or Section 13.1(j) shall
occur, any unused portion of the credit hereunder shall forthwith terminate and
each of the Lenders shall be relieved of all further obligations to make
Revolving Credit Loans to the Borrowers and the Administrative Agent shall be
relieved of all further obligations to cause the Issuing Bank to issue, extend
or renew any Letters of Credit. If any other Event of Default shall have
occurred and be continuing, the Administrative Agent may and, upon the request
of the Required Lenders, shall, by notice to the Borrowers, 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
Lenders shall be relieved of all further obligations to make Loans and the
Administrative Agent shall be relieved of all further obligations to issue,
extend or renew Letters of Credit. No termination of the credit hereunder shall
relieve the Borrowers or any of their Subsidiaries of any of the Obligations.

     13.3. Remedies. In case any one or more of the Events of Default shall have
           --------
occurred and be continuing, and whether or not the Lenders shall have
accelerated the maturity of the Revolving Credit Loans pursuant to Section 13.1,
each Lender, if owed any amount with respect to the Revolving Credit 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 Lender 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 Lender. No remedy
herein conferred upon any Lender or the Administrative Agent or the holder of
any Revolving Credit 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.

     13.4. Distribution of Collateral Proceeds. In the event that, following the
           -----------------------------------
occurrence or during the continuance of any Default or Event of Default, the
Administrative Agent or any Lender, 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:

<PAGE>

                                      -93-

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

          (b) Second, to all other Obligations (except Obligations owing to any
     Lender in respect of Interest Rate Agreements) in such order or preference
     as the Required Lenders may determine; provided, however, that (i)
                                            --------  -------
     distributions shall be made (A) pari passu among Obligations with respect
                                     ---- -----
     to the Administrative Agent's Fee and all other Obligations and (B) with
     respect to each type of Obligation owing to the Lenders, such as interest,
     principal, fees and expenses, among the Lenders pro rata, and (ii) the
                                                     --- ----
     Administrative Agent may in its discretion make proper allowance to take
     into account any Obligations not then due and payable;

          (c) Third, to any Obligations owing to any Lender in respect of
     Interest Rate Agreements in such order or preference as the Required
     Lenders may determine; provided, however, that (i) with respect to each
                            --------  -------
     such Obligation owing to the Lenders, among the Lenders pro rata, and (ii)
                                                             --- ----
     the Administrative Agent may in its discretion make proper allowance to
     take into account any such Obligations not then due and payable;

          (d) Fourth, upon payment and satisfaction in full or other provisions
     for payment in full satisfactory to the Lenders and the Administrative
     Agent of all of the Obligations, to the payment of any obligations required
     to be paid pursuant to Section 9-608(a)(1)(C) or 9-615(a)(3) of the Uniform
     Commercial Code of the Commonwealth of Massachusetts; and

          (e) Fifth, the excess, if any, shall be returned to the Borrowers or
     to such other Persons as are entitled thereto.

                          14. THE ADMINISTRATIVE AGENT.
                              ------------------------

     14.1. Authorization.
           -------------

          (a) The Administrative Agent is authorized to take such action on
     behalf of each of the Lenders and to exercise all such powers as are
     hereunder and under any of the other Loan Documents and any related
     documents delegated to the Administrative Agent, together with such powers
     as are reasonably incident thereto, including the authority, without the
     necessity of any notice to or further consent of the Lenders, from time to
     time to take any action with respect to any Collateral or the Security
     Documents which may be necessary to perfect, maintain perfected or insure
     the priority of the security interest in and liens upon the Collateral
     granted pursuant to the Security Documents, provided that no duties or
                                                 --------
     responsibilities not expressly assumed herein or therein shall be implied
     to have been assumed by the Administrative Agent.

          (b) The relationship between the Administrative Agent and each of the
     Lenders is that of an independent contractor. The use of the term
     "Administrative Agent" is for convenience only and is used to describe, as
      --------------------
     a form of convention, the independent contractual relationship between the
     Administrative Agent and each of the Lenders. 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 Administrative
     Agent and any of the Lenders.

          (c) As an independent contractor empowered by the Lenders to exercise
     certain rights and perform certain duties and responsibilities hereunder
     and under the other Loan Documents, the Administrative Agent is
     nevertheless a "representative" of the Lenders, as that term is defined in
                     --------------
     Article 1 of the Uniform Commercial Code, for purposes of actions for the
     benefit of the Lenders and the Administrative Agent with respect to all
     collateral security and guaranties contemplated by the Loan Documents. Such
     actions include the designation of the Administrative 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 Lenders and the Administrative Agent.

<PAGE>

                                      -95-

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

     14.3. No Liability. Neither the Administrative 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 Administrative
Agent or such other Person, as the case may be, may be liable for losses due to
its willful misconduct or gross negligence.

     14.4. No Representations.
           ------------------

          14.4.1. General. The Administrative Agent shall not be responsible for
                  -------
     the execution or validity or enforceability of this Credit Agreement, the
     Revolving Credit Notes, the Letters of Credit, any of the other Loan
     Documents or any instrument at any time constituting, or intended to
     constitute, collateral security for the Revolving Credit Notes, or for the
     value of any such collateral security or for the validity, enforceability
     or collectability of any such amounts owing with respect to the Revolving
     Credit 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
     Borrowers or any of their Subsidiaries, or be bound to ascertain or inquire
     as to the performance or observance of any of the terms, conditions,
     covenants or agreements herein or in any instrument at any time
     constituting, or intended to constitute, collateral security for the
     Revolving Credit Notes or to inspect any of the properties, books or
     records of the Borrowers or any of their Subsidiaries. The Administrative
     Agent shall not be bound to ascertain whether any notice, consent, waiver
     or request delivered to it by the Borrowers or any holder of any of the
     Revolving Credit Notes shall have been duly authorized or is true, accurate
     and complete. The Administrative Agent has not made nor does it now make
     any representations or warranties, express or implied, nor does it assume
     any liability to the Lenders, with respect to the credit worthiness or

<PAGE>

                                      -96-

     financial conditions of the Borrowers or any of their Subsidiaries. Each
     Lender acknowledges that it has, independently and without reliance upon
     the Administrative Agent or any other Lender, 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.

          14.4.2. Closing Documentation, etc. For purposes of determining
                  --------------------------
     compliance with the conditions set forth in Section 11, each Lender 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 Administrative Agent or the Arranger
     to such Lender for consent, approval, acceptance or satisfaction, or
     required thereunder to be to be consent to or approved by or acceptable or
     satisfactory to such Lender, unless an officer of the Administrative Agent
     or the Arranger active upon the Borrowers' account shall have received
     notice from such Lender prior to the Closing Date specifying such Lender's
     objection thereto and such objection shall not have been withdrawn by
     notice to the Administrative Agent or the Arranger to such effect on or
     prior to the Closing Date.

     14.5. Payments.
           --------

          14.5.1. Payments to Administrative Agent. A payment by the Borrowers
                  --------------------------------
     to the Administrative Agent hereunder or any of the other Loan Documents
     for the account of any Lender shall constitute a payment to such Lender.
     The Administrative Agent agrees promptly to distribute to each Lender such
     Lender's pro rata share of payments received by the Administrative Agent
              --- ----
     for the account of the Lenders except as otherwise expressly provided
     herein or in any of the other Loan Documents.

          14.5.2. Distribution by Administrative Agent. If in the opinion of the
                  ------------------------------------
     Administrative Agent the distribution of any amount received by it in such
     capacity hereunder, under the Revolving Credit 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
     Administrative Agent is to be repaid, each Person to whom any such
     distribution shall have been made shall either repay to the Administrative
     Agent its proportionate share of the

<PAGE>

                                      -97-

     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.

          14.5.3. Delinquent Lenders. Notwithstanding anything to the contrary
                  ------------------
     contained in this Credit Agreement or any of the other Loan Documents, any
     Lender that fails (a) to make available to the Administrative Agent its pro
                                                                             ---
     rata share of any Loan or to purchase any Letter of Credit Participation or
     ----
     (b) to comply with the provisions of Section 16.1 with respect to making
     dispositions and arrangements with the other Lenders, where such Lender'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
            --- ----
     Lenders, in each case as, when and to the full extent required by the
     provisions of this Credit Agreement, shall be deemed delinquent (a
     "Delinquent Lender") and shall be deemed a Delinquent Lender until such
      ---------- ------
     time as such delinquency is satisfied. A Delinquent Lender shall be deemed
     to have assigned any and all payments due to it from the Borrowers, whether
     on account of outstanding Revolving Credit Loans, Unpaid Reimbursement
     Obligations, interest, fees or otherwise, to the remaining nondelinquent
     Lenders for application to, and reduction of, their respective pro rata
                                                                    --- ----
     shares of all outstanding Revolving Credit Loans and Unpaid Reimbursement
     Obligations. The Delinquent Lender hereby authorizes the Administrative
     Agent to distribute such payments to the nondelinquent Lenders in
     proportion to their respective pro rata shares of all outstanding Revolving
                                    --- ----
     Credit Loans and Unpaid Reimbursement Obligations. A Delinquent Lender
     shall be deemed to have satisfied in full a delinquency when and if, as a
     result of application of the assigned payments to all outstanding Revolving
     Credit Loans and Unpaid Reimbursement Obligations of the nondelinquent
     Lenders, the Lenders' respective pro rata shares of all outstanding
                                      --- ----
     Revolving Credit 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.

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

     14.7. Indemnity. The Lenders ratably agree hereby to indemnify and hold
           ---------
harmless the Administrative Agent and its affiliates from and against any and
all claims, actions and suits (whether groundless or otherwise),

<PAGE>

                                      -98-

losses, damages, costs, expenses (including any expenses for which the
Administrative Agent or such affiliate has not been reimbursed by the Borrowers
as required by Section 16.2), and liabilities of every nature and character
arising out of or related to this Credit Agreement, the Revolving Credit Notes,
or any of the other Loan Documents or the transactions contemplated or evidenced
hereby or thereby, or the Administrative Agent's actions taken hereunder or
thereunder, except to the extent that any of the same shall be directly caused
by the Administrative Agent's willful misconduct or gross negligence.

     14.8. Administrative Agent as Lender. In its individual capacity, Fleet
           ------------------------------
shall have the same obligations and the same rights, powers and privileges in
respect to its Commitment and the Revolving Credit Loans made by it, and as the
holder of any of the Revolving Credit Notes and as the purchaser of any Letter
of Credit Participations, as it would have were it not also the Administrative
Agent.

     14.9. Resignation. The Administrative Agent may resign at any time by
           -----------
giving sixty (60) days prior written notice thereof to the Lenders and the
Borrowers. Upon any such resignation, the Required Lenders shall have the right
to appoint a successor Administrative Agent. Unless a Default or Event of
Default shall have occurred and be continuing, such successor Administrative
Agent shall be reasonably acceptable to the Borrowers. If no successor
Administrative Agent shall have been so appointed by the Required Lenders and
shall have accepted such appointment within thirty (30) days after the retiring
Administrative Agent's giving of notice of resignation, then the retiring
Administrative Agent may, on behalf of the Lenders, appoint a successor
Administrative Agent, which shall be a financial institution having a rating of
not less than A or its equivalent by S&P. Upon the acceptance of any appointment
as Administrative Agent hereunder by a successor Administrative Agent, such
successor Administrative Agent shall thereupon succeed to and become vested with
all the rights, powers, privileges and duties of the retiring Administrative
Agent, and the retiring Administrative Agent shall be discharged from its duties
and obligations hereunder. After any retiring Administrative 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 Administrative Agent.

     14.10. Notification of Defaults and Events of Default. Each Lender hereby
            ----------------------------------------------
agrees that, upon learning of the existence of a Default or an Event of Default,
it shall promptly notify the Administrative Agent thereof. The Administrative
Agent hereby agrees that upon receipt of any notice

<PAGE>

                                      -99-

under this Section 14.10 it shall promptly notify the other Lenders of the
existence of such Default or Event of Default.

     14.11. 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 Administrative Agent shall, if (a)
so requested by the Required Lenders and (b) the Lenders have provided to the
Administrative Agent such additional indemnities and assurances against expenses
and liabilities as the Administrative Agent may reasonably request, proceed to
enforce the provisions of the Security Documents authorizing the sale or other
disposition of all or any part of the Collateral and exercise all or any such
other legal and equitable and other rights or remedies as it may have in respect
of such Collateral. The Required Lenders may direct the Administrative Agent in
writing as to the method and the extent of any such sale or other disposition,
the Lenders hereby agreeing to indemnify and hold the Administrative Agent,
harmless from all liabilities incurred in respect of all actions taken or
omitted in accordance with such directions, provided that the Administrative
                                            --------
Agent need not comply with any such direction to the extent that the
Administrative Agent reasonably believes the Administrative Agent's compliance
with such direction to be unlawful or commercially unreasonable in any
applicable jurisdiction.

                        15. ASSIGNMENT AND PARTICIPATION.
                            ----------------------------

     Loans at the time owing to it, the Revolving Credit Notes held by it and
     its participating interest in the risk relating to any Letters of Credit);

     required in connection with any assignment by a Lender to (i) an existing

     and Acceptance"), together with any Notes subject to such assignment. Upon
     --- ----------

     provided in such Assignment and Acceptance, have the rights and obligations
     of a Lender hereunder, and (z) the assigning Lender shall, to the extent
     provided in such assignment and upon payment to the Administrative Agent of
     the registration fee referred to in Section 15.3, be released from its
     obligations under this Credit Agreement.

     15.2. Certain Representations and Warranties; Limitations; Covenants. By

"Register") for the recordation of the names and addresses of the Lenders and
 --------
the Commitment Percentage of, and principal amount of the Revolving Credit Loans
owing to and Letter of Credit Participations purchased by, the Lenders from time
to time. The entries in the Register shall be conclusive, in the absence of
manifest error, and the Borrowers, the Administrative Agent and the Lenders may
treat each Person whose name is recorded in the Register as a Lender hereunder
for all purposes of this Credit Agreement. The Register shall be available for
inspection by the Borrowers and the

<PAGE>

                                     -102-

Lenders at any reasonable time and from time to time upon reasonable prior
notice. Upon each such recordation, the assigning Lender agrees to pay to the
Administrative Agent a registration fee in the sum of $3,500.

     15.4. New Notes. Upon its receipt of an Assignment and Acceptance executed
           ---------
by the parties to such assignment, together with each Revolving Credit Note

Borrowers, at its own expense, shall execute and deliver to the Administrative
Agent, in exchange for each surrendered Revolving Credit Note, a new Revolving
Credit Note to the order of such Assignee in an amount equal to the amount
assumed by such Assignee pursuant to such Assignment and Acceptance and, if the
assigning Lender has retained some portion of its obligations hereunder, a new
Revolving Credit Note to the order of the assigning Lender in an amount equal to
the amount retained by it hereunder. Such new Revolving Credit Notes shall
provide that they are replacements for the surrendered Notes, shall be in an
aggregate principal amount equal to the aggregate principal amount of the
surrendered Revolving Credit Notes, shall be dated the effective date of such
Assignment and Acceptance and shall otherwise be in substantially the form of
the assigned Revolving Credit Notes. To the extent requested by an Assignee, the
Borrowers shall, within five (5) days of issuance of any new Revolving Credit
Notes pursuant to this Section 15.4, deliver an opinion of counsel, addressed to
the Lenders and the Administrative Agent, relating to the due authorization,
execution and delivery of such new Revolving Credit Notes and the legality,
validity and binding effect thereof, in form and substance satisfactory to the
Lenders. The surrendered Revolving Credit Notes shall be cancelled and returned
to the Borrowers.

     15.5. Participations. Each Lender may sell participations to one or more
           --------------
Lenders or other entities in all or a portion of such Lender's rights and
obligations under this Credit Agreement and the other Loan Documents; provided
                                                                      --------
that (a) each such participation shall be in an amount of not less than
$2,500,000, (b) any such sale or participation shall not affect the rights and
duties of the selling Lender hereunder to the Borrowers and (c) the only rights
granted to the participant pursuant to such participation arrangements with
respect to waivers, amendments or modifications of the Loan Documents shall be
the rights to approve waivers, amendments or modifications that would reduce the
principal of or the interest rate on any Loans, extend the term or increase the
amount of the Commitment of such Lender as it relates to such participant,
reduce the amount of any Commitment Fee or Letter of Credit Fees to which such
participant is

<PAGE>

                                     -103-

entitled or extend any regularly scheduled payment date for principal or
interest.

     15.6. Assignee or Participant Affiliated with the Borrowers. If any
           -----------------------------------------------------
assignee Lender is an Affiliate of any Borrower, then any such assignee Lender
shall have no right to vote as a Lender hereunder or under any of the other Loan
Documents for purposes of granting consents or waivers or for purposes of
agreeing to amendments or other modifications to any of the Loan Documents or
for purposes of making requests to the Administrative Agent pursuant to Section
13.1 or Section 13.2, and the determination of the Required Lenders shall for
all purposes of this Credit Agreement and the other Loan Documents be made
without regard to such assignee Lender's interest in any of the Revolving Credit
Loans or Reimbursement Obligations. If any Lender sells a participating interest
in any of the Revolving Credit Loans or Reimbursement Obligations to a
participant, and such participant is a Borrower or an Affiliate of a Borrower,
then such transferor Lender shall promptly notify the Administrative Agent of
the sale of such participation. A transferor Lender shall have no right to vote
as a Lender hereunder or under any of the other Loan Documents for purposes of
granting consents or waivers or for purposes of agreeing to amendments or
modifications to any of the Loan Documents or for purposes of making requests to
the Administrative Agent pursuant to Section 13.1 or Section 13.2 to the extent
that such participation is beneficially owned by a Borrower or any Affiliate of
a Borrower, and the determination of the Required Lenders shall for all purposes
of this Credit Agreement and the other Loan Documents be made without regard to
the interest of such transferor Lender in the Revolving Credit Loans or
Reimbursement Obligations to the extent of such participation.

     15.7. Miscellaneous Assignment Provisions. Any assigning Lender shall
           -----------------------------------
retain its rights to be indemnified pursuant to Section 16.3 with respect to any
claims or actions arising prior to the date of such assignment. If any Reference
Lender transfers all of its interest, rights and obligations under this Credit
Agreement, the Administrative Agent shall, in consultation with the Borrowers
and with the consent of the Borrowers and the Required Lenders, appoint another
Lender to act as a Reference Lender hereunder. Anything contained in this
Section 15 to the contrary notwithstanding, any Lender may at any time pledge or
assign a security interest in all or any portion of its interest and rights
under this Credit Agreement (including all or any portion of its Revolving
Credit Notes) to secure obligations of such Lender, including any pledge or
assignment to secure obligations to (a) any of the twelve Federal Reserve Banks
organized under Section 4 of the Federal Reserve Act, 12 U.S.C. Section 341 and
(b) with respect to any Lender that is a fund that invests in bank loans, to any
lender or any trustee for, or any other representative of,

<PAGE>

                                     -104-

holders of obligations owed or securities issued by such fund as security for
such obligations or securities or any institutional custodian for such fund or
for such lender. Any foreclosure or similar action by any Person in respect of
such pledge or assignment shall be subject to the other provisions of this
Section 15. No such pledge or the enforcement thereof shall release the pledgor
Lender from its obligations hereunder or under any of the other Loan Documents,
provide any voting rights hereunder to the pledgee thereof, or affect any rights
or obligations of the Borrowers or Administrative Agent hereunder.

     15.8. Assignment by a Borrower. No Borrower shall assign or transfer any of
           ------------------------
its rights or obligations under any of the Loan Documents without the prior
written consent of each of the Lenders.

                     16. PROVISIONS OF GENERAL APPLICATIONS.
                         ----------------------------------

     16.1. Setoff. Each Borrower hereby grants to the Administrative Agent and
           ------
each of the Lenders a continuing lien, security interest and right of setoff as
security for all liabilities and obligations to the Administrative Agent and
each Lender, whether now existing or hereafter arising, upon and against all
deposits, credits, collateral and property (other than funds or other property
held in trust or as collateral for an obligation of the Borrowers or their
Subsidiaries to a third party pursuant to a written agreement whereby the
Administrative Agent or any Lender has acknowledged and consented to such
arrangement), now or hereafter in the possession, custody, safekeeping or
control of the Administrative Agent or such Lender or any Lender Affiliate and
their successors and assigns or in transit to any of them. Regardless of the
adequacy of any collateral, if any of the Obligations are due and payable and
have not been paid or any Event of Default shall have occurred, any deposits or
other sums credited by or due from any of the Lenders to any Borrower and any
securities or other property of any Borrower in the possession of such Lender
may be applied to or set off by such Lender 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 any Borrower to such
Lender. ANY AND ALL RIGHTS TO REQUIRE ANY LENDER TO EXERCISE ITS RIGHTS OR
REMEDIES WITH RESPECT TO ANY OTHER COLLATERAL WHICH SECURES THE OBLIGATIONS,
PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH RESPECT TO SUCH DEPOSITS, CREDITS
OR OTHER PROPERTY OF ANY BORROWER ARE HEREBY KNOWINGLY, VOLUNTARILY AND
IRREVOCABLY WAIVED. Each of the Lenders agree with each other Lender that (a) if
an amount to be set off is to be applied to Indebtedness of the Borrowers to
such Lender, other than Indebtedness evidenced by the Revolving Credit Notes
held by such Lender or constituting Reimbursement Obligations owed to such

<PAGE>

                                     -105-

Lender, such amount shall be applied ratably to such other Indebtedness and to
the Indebtedness evidenced by all such Notes held by such Lender or constituting
Reimbursement Obligations owed to such Lender, and (b) if such Lender shall
receive from the Borrowers, whether by voluntary payment, exercise of the right
of setoff, counterclaim, cross action, enforcement of the claim evidenced by the
Revolving Credit Notes held by, or constituting Reimbursement Obligations owed
to, such Lender by proceedings against the Borrowers 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 Revolving Credit Note or Revolving Credit Notes held by, or Reimbursement
Obligations owed to, such Lender any amount in excess of its ratable portion of
the payments received by all of the Lenders with respect to the Revolving Credit
Notes held by, and Reimbursement Obligations owed to, all of the Lenders, such
Lender will make such disposition and arrangements with the other Lenders with
respect to such excess, either by way of distribution, pro tanto assignment of
                                                       --- -----
claims, subrogation or otherwise as shall result in each Lender receiving in
respect of the Revolving Credit 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 Lender, such disposition and arrangements shall be rescinded and the
amount restored to the extent of such recovery, but without interest.

     16.2. Expenses. The Borrowers jointly and severally agree to pay (a) the
           --------

Agreement including, without limitation, all personal property or Indebtedness

disbursements of any Lender, the Issuing Bank or the Administrative Agent
incurred in connection with UCC searches, UCC filings, intellectual property
searches, intellectual property filings or mortgage recordings. Each Borrower
authorizes the Administrative Agent and each of the Lenders to debit any account
maintained by such Borrower with such Lender for any of the foregoing fees,
expenses or other amounts due and payable by such Borrower under this Credit
Agreement or under any of the other Loan Documents. The covenants contained in
this Section 16.2 shall survive payment or satisfaction in full of all other
obligations.

     16.3. Indemnification. The Borrowers jointly and severally agree to
           ---------------
indemnify and hold harmless the Administrative Agent, the Issuing Bank, the
Lenders and their affiliates from and against any and all claims, actions and
suits whether groundless or otherwise, and from and against any and all
liabilities, losses, damages and expenses of every nature and character arising
out of this Credit Agreement or any of the other Loan Documents or the
transactions contemplated hereby including, without limitation, (a) any actual

Borrowers and their Subsidiaries shall not be liable for any claims, actions,
suits, liabilities, losses, damages, or expenses arising solely from the gross
negligence or willful misconduct of any Lender as determined by a final,
non-appealable judgment from a court of competent jurisdiction. In litigation,
or the preparation therefor, the Lenders, the Issuing Bank and the
Administrative Agent and their affiliates shall be entitled to select their own
counsel and, in addition to the foregoing indemnity, the Borrowers jointly and
severally agree to pay promptly the reasonable fees and expenses of such

OR ENFORCEMENT OF THE LOAN DOCUMENTS AND AGREES THAT THEY WILL NOT SEEK TO
CONSOLIDATE ANY SUCH ACTION WITH ANY OTHER ACTION IN WHICH A JURY TRIAL CANNOT

damages or any damages other than, or in addition to, actual damages. The

Lender or the Administrative Agent would not, in the event of litigation, seek
to enforce the foregoing waivers and (b) acknowledges that the Administrative
Agent and the Lenders have been induced to enter into this Credit Agreement and
the other Loan Documents to which it is a party by, among other things, the
waivers and certifications contained herein.

     16.12. Consents, Amendments, Waivers, Etc. Any consent or approval required
            ----------------------------------
or permitted by this Credit Agreement to be given by the Lenders may be given,
and any term of this Credit Agreement, the other Loan Documents or any other
instrument related hereto or mentioned herein may be amended, and the
performance or observance by the Borrowers or any of their Subsidiaries of any
terms of this Credit Agreement, the other Loan Documents or such other
instrument or the continuance of any Default or Event of Default may be waived
(either generally or in a particular instance and either retroactively or
prospectively) with, but only with, the written consent of the Borrowers and the
written consent of the Required Lenders. Notwithstanding the foregoing, no
amendment, modification or waiver shall:

          (a) without the written consent of the Borrowers and each Lender
     directly affected thereby:

               (i) reduce or forgive the principal amount of any Loans or
          Reimbursement Obligations, or reduce the rate of interest on the
          Revolving Credit Notes or the amount of the Commitment Fee or Letter
          of Credit Fees (other than interest accruing pursuant to Section
          5.11.2 following the effective date of any waiver by the Required
          Lenders of the Default or Event of Default relating thereto);

               (ii) increase the amount of such Lender's Commitment or extend
          the expiration date of such Lender's Commitment;

<PAGE>

                                     -113-

               (iii) postpone or extend the Maturity Date or any other regularly
          scheduled dates for payments of principal of, or interest on, the
          Revolving Credit Loans or Reimbursement Obligations or any Fees or
          other amounts payable to such Lender (it being understood that (A) a
          waiver of the application of the default rate of interest pursuant to
          Section 5.11.2, and (B) any vote to rescind any acceleration made
          pursuant to Section 13.1 of amounts owing with respect to the
          Revolving Credit Loans and other Obligations shall require only the
          approval of the Required Lenders); and

               (iv) other than pursuant to a transaction permitted by the terms
          of this Credit Agreement, release all or substantially all of the
          Collateral or release all or substantially all of the Guarantors from
          their guaranty obligations under the Guaranties (excluding, if any
          Borrower or any Subsidiary of a Borrower becomes a debtor under the
          federal Bankruptcy Code, the release of "cash collateral", as defined
          in Section 363(a) of the federal Bankruptcy Code pursuant to a cash
          collateral stipulation with the debtor approved by the Required
          Lenders);

          (b) without the written consent of all of the Lenders, amend or waive
     this Section 16.12, the definition of Required Lenders, or any other
     provision hereof specifying the percentage of Lenders required to approve
     or consent to any action, amendment or waiver;

          (c) without the written consent of the Supermajority Lenders, amend
     the definition of "Borrowing Base" or any defined term used therein; and

          (d) without the written consent of the Administrative Agent, amend or
     waive Section 14, the amount or time of payment of the Administrative
     Agent's Fee or any Letter of Credit Fees payable for the Administrative
     Agent's account or any other provision applicable to the Administrative
     Agent.

No waiver shall extend to or affect any obligation not expressly waived or
impair any right consequent thereon. No course of dealing or delay or omission
on the part of the Administrative Agent or any Lender in exercising any right
shall operate as a waiver thereof or otherwise be prejudicial thereto. No notice
to or demand upon the Borrowers shall entitle the Borrowers to other or further
notice or demand in similar or other circumstances.
