other reason, and excluding (a) any accounts receivable arising out of
transactions with respect to which there shall exist any payables, discounts
other than prompt payment discounts in the ordinary course of business
consistent with past practices, or other similar offsets or reductions, (b) any
accounts receivable that are due from any single account debtor if more than
twenty percent (20%) of the aggregate amount of all accounts receivable owing to
the Borrower from such account debtor would otherwise not be Eligible
Receivables, and (c) any accounts receivable owing to the Borrower from any
distributor that has the right to return unsold goods to the Borrower (but only
to the extent of such right) which are 60 days or more past due under the

(S)2.  REVOLVING CREDIT LOANS.
       --------- ------ -----

(S)2.1. Commitment to Lend. Subject to the terms and conditions set forth in
        ---------- -- ----
this Agreement, the Bank agrees to lend to the Borrower and the Borrower may
borrow and reborrow from time to time between the Closing Date and the Maturity
Date, upon notice to the Bank given in accordance with (S)2.6 hereof, such sums
as are requested by the Borrower up to a maximum principal amount outstanding
(after giving effect to all amounts requested and the amount of the Total Loan
Outstandings) at any one time not to exceed the lesser of (a) the Borrowing
Base, or (b) $14,360,000, as such amount maybe reduced pursuant to (S)2.2
hereof (the "Loan Commitment"). Each request for Loans hereunder shall
constitute a representation by the Borrower that the conditions set forth in
(S)(S) 9 and 10 hereof have been satisfied on the date of such request.

(S)2.2. Reduction of Loan Commitment. The Borrower shall have the right at any
        --------- -- ---- ----------
time and from time to time upon five (5) Business Days' written notice to the
Bank to reduce by $500,000 or an integral multiple thereof or terminate entirely
the amount of the unborrowed portion of the Loan Commitment, whereupon the Loan
Commitment shall be reduced by the amount specified in such notice or
terminated, as the case may be. Upon the effective date of any such reduction or
termination, the Borrower shall pay to the Bank the full amount of any
Commitment Fee then accrued on the amount of the reduction. No reduction of the
Loan Commitment hereunder shall be subject to reinstatement.

(S)2.3. Note. The Loans shall be evidenced by the Note of the Borrower in
        ----
substantially the form of Exhibit A hereto, dated the Closing Date with
                          ------- -
appropriate insertions, representing the obligation of the Borrower to pay the
Loan Commitment or, if less, the aggregate unpaid principal amount of all Loans
made by the Bank hereunder, plus interest accrued thereon, as set forth below.
The Borrower irrevocably authorizes the Bank to make or cause to be made, in
connection with a Drawdown Date of any Loan or at the time of receipt of any
payment of principal on the Note, an appropriate notation on the Bank's records
reflecting the making

                                                                              47
<PAGE>

of such Loan or the receipt of such payment (as the case may be). The
outstanding amount of the Loans set forth on the Bank's record shall be prima
                                                                        -----
facie evidence of the principal amount thereof owing and unpaid to the Bank, but
-----
the failure to record, or any error in so recording, any such amount shall not
limit or otherwise affect the obligations of the Borrower hereunder or under the
Note to make payments of principal of or interest on the Note when due.

(S)2.4. Interest on Loans. The outstanding principal amount of the Loans shall
        -------- -- -----
bear interest at the rate per annum equal to (a) the Base Rate, or (b) at the
Borrower's option as provided herein, at the Eurodollar Rate plus two percent
(2%). Interest shall be payable (i) monthly in arrears on the first Business Day
of each calendar month of each year, commencing June 1, 1999, on Base Rate
Loans, and (ii) on the last day of the applicable Interest Period, and, if such
Interest Period is longer than 30 days, also monthly during such Interest Period
on Eurodollar Loans, and (iii) on the Maturity Date for all Loans.

(S)2.5.  Election of Eurodollar Rate; Notice of Election; Interest Periods;
         -------- -- ---------- ----  ------ -- --------  -------- -------
Minimum Amounts.
------- -------

          (a) At the Borrower's option, so long as no Default or Event of
     Default has occurred and is then continuing, the Borrower may (i) elect to
     convert any Base Rate Loan or a portion thereof to a Eurodollar Loan, (ii)
     at the time of any Loan and Letter of Credit Request, specify that such
     requested Loan shall be a Eurodollar Loan, or (iii) upon expiration of the
     applicable Interest Period, elect to maintain an existing Eurodollar Loan
     as such, provided that the Borrower gives notice to the Bank pursuant to
              --------
     (S)2.5(b) hereof. Upon determining any Eurodollar Rate, the Bank shall
     forthwith provide notice thereof to the Borrower, and each such notice to
     the Borrower shall be considered prima facie correct and binding, absent
                                      ----- -----
     manifest error.

          (b) Three (3) Eurodollar Business Days prior to the making of any
     Eurodollar Loan or the conversion of any Base Rate Loan to a Eurodollar
     Loan, or, in the case of an outstanding Eurodollar Loan, the expiration
     date of the applicable Interest Period, the Borrower shall give written,
     telex or telecopy notice received by the Bank not later than 12:00 noon
     (Boston time) of its election pursuant to (S)2.5(a). Each such notice
     delivered to the Bank shall specify the aggregate principal amount of the
     Loans to be borrowed or maintained as or converted to Eurodollar Loans and
     the requested duration of the Interest Period that will be applicable to
     such Eurodollar Loan, and shall be irrevocable and binding upon the
     Borrower. If the Borrower shall fail to give the Bank notice of its
     election hereunder together with all of the other information required by
     this (S)2.5(b) with respect to any Loan, whether at the end of an Interest
     Period or otherwise, such Loan shall be deemed a Base Rate Loan.

          (c) Notwithstanding anything herein to the contrary, the Borrower may
     not specify an Interest Period that would extend beyond the Maturity Date.

          (d) All Eurodollar Loans shall be in a minimum amount of not less than
     $1,000,000. In no event shall the Borrower have more than five (5)
     different maturities of Eurodollar Loans outstanding at any time.

                                                                              48
<PAGE>

(S)2.6. Requests for Revolving Credit Loans. The Borrower shall give to the Bank
        -------- --- --------- ------ -----
written notice in the form of Exhibit B hereto (or telephonic notice confirmed
                              ------- -
by telecopy the same day in the form of Exhibit B hereto) of each Loan requested
                                        ------- -
hereunder (a "Loan and Letter of Credit Request") not later than 12:00 noon (a)
on the proposed Drawdown Date of any Base Rate Loan, or (b) three Eurodollar
Business Days prior to the Drawdown Date of any Eurodollar Loan. Each such
notice shall be given by the Borrower and shall specify the principal amount of
the Loan requested and shall include a current Loan and Letter of Credit
Request, reflecting the Total Loan Outstandings. Each Loan and Letter of Credit
Request shall be made in the Minimum amount of $25,000 or a greater integral
multiple of $10,000, and shall be irrevocable and binding on the Borrower and
shall obligate the Borrower to accept the Loan requested from the Bank on the
proposed Drawdown Date. Each of the representations and warranties made by or on
behalf of the Borrower to the Bank in this Agreement or any other Loan Document
shall be true and correct in all material respects when made and shall, for all
purposes of this Agreement, be deemed to be repeated on and as of the date of
the submission of any Loan and Letter of Credit Request and on and as of the
Drawdown Date of such Loan or the date of issuance of such Credit Instrument
(except to the extent of changes resulting from transactions contemplated or
permitted by this Agreement and the other Loan Documents and changes occurring
in the ordinary course of business that singly or in the aggregate are not
materially adverse and to the extent that such representations and warranties
expressly relate to an earlier date).

(S)2.7. Interest on Overdue Amounts. Except as otherwise limited by (S)4.4
        -------- -- ------- -------
hereof, amounts due hereunder not paid within ten (10) days of the due date will
be subject to a late payment charge equal to five percent (5%) of such overdue
amount.

(S)2.8. Termination of Credit. If any Event of Default shall occur, the Bank
        ----------- -- ------
may, by notice to the Borrower, terminate the unused portion of the Total
Commitment hereunder, and upon such notice being given such unused portion of
the Total Commitment hereunder shall terminate immediately and the Bank shall be
relieved of all further obligations to make Loans to the Borrower, to issue
Credit Instruments for the account of the Borrower hereunder, to make ACH
Advances to the Borrower and to effect Foreign Exchange Transactions for the
Borrower, provided that if an Event of Default specified in (S)(S)11(g) or (h)
          --------
hereof shall occur, the Total Commitment shall terminate without the requirement
of notice from the Bank. No termination of any portion of the Total Commitment
hereunder shall relieve the Borrower of any of its existing Obligations to the
Bank hereunder or elsewhere. Upon termination of the Total Commitment under this
(S)2.8, all Loans, all ACH Advances and all amounts outstanding with respect to
Foreign Exchange Transactions shall become immediately due and payable.

(S)2.9. Maturity of the Loans. The Loans shall be due and payable on the
        -------- -- --- -----
Maturity Date. The Borrower promises to pay on the Maturity Date all Loans
outstanding on such date, together with any and all accrued and unpaid interest
thereon.

(S)2.10. Optional Prepayments or Repayments of Loans. The Borrower shall have
         -------- ----------- -- ---------- -- -----
the right, at its election, to repay or prepay the outstanding amount of the
Loans, as a whole or in part, at any time without penalty or premium. The
Borrower shall give the Bank, no later than 12:00 noon, Boston time, on the
Business Day of such proposed prepayment or repayment, written notice (or
telephonic notice confirmed in writing or by telecopy by the Borrower) of

                                                                              49
<PAGE>

any proposed prepayment or repayment pursuant to this (S)2.10, specifying the
proposed date of repayment of Loans and the principal amount to be paid,
provided that a Eurodollar Loan may be repaid only on the last day of the
--------
applicable Interest Period.

(S)2.11.  Mandatory Repayment. If at any time the aggregate amount of the Total
          --------- ---------
Loan Outstandings shall exceed (a) the Loan Commitment (whether by reduction of
the Loan Commitment or otherwise) or (b) the Borrowing Base then in effect, the
Borrower shall immediately make a payment to the Bank in the amount required to
eliminate any such excess.

(S)2.12.  Lockbox Provisions.
          ------- ----------

               (a) The Borrower agrees to maintain at the Bank its existing
     depository account established pursuant to the Schedule to Cash Management
     Master Agreement for Lockbox Service dated as of November 3, 1998 (the
     "Lockbox Account") upon the terms stated therein.

               (b) The Borrower agrees that all amounts received by the Bank in
     the Lockbox Account will be the sole and exclusive property of the Bank.
     If, notwithstanding the existence of the lockbox accounts, the Borrower
     receives any cash proceeds of any of the Collateral, whether in the form of
     money, checks or otherwise, the Borrower will hold such cash proceeds in
     trust for the benefit of the Bank and turn such cash proceeds promptly over
     to the Bank in the identical form received, with appropriate endorsements.
     The Bank shall, on the second Business Day immediately following the day of
     the Bank's receipt of payments into the Lockbox Account or cash proceeds
     from the Borrower or on such later date as the Bank determines that good
     funds will be received, and on a provisional basis until final receipt of
     good funds, credit to the Obligations as contemplated by (S)2.12(c) all
     such cash proceeds which are in the form of money, checks or like items.
     For purposes of the foregoing provisions of this (S)2.12(b), the Bank shall
     not be deemed to have received any such cash proceeds on any day unless
     received by the Bank before 3:00 p.m. (Boston time) on such day. The
     Borrower further acknowledges and agrees that any such provisional credit
     shall be subject to reversal if final collection in good funds of the
     related item is not received by the Bank in accordance with the Bank's
     customary procedures and practices for collecting provisional items.

               (c) All payments to be applied towards the Obligations pursuant
     toss (S)2.12(b) shall, except as otherwise provided, be applied to the
     Obligations as follows: (i) first, to any unpaid Reimbursement Obligations;
                                 -----
     (ii) second, to any interest on the Loans then due and payable (and if
          ------
     interest is due and payable on more than one Loan, in such order as the
     Bank may determine in its own discretion); (iii) third, (A) first, to the
                                                      -----
     outstanding principal amount of the Loans, and (B) second to any other
     outstanding Obligations; (iv) fourth, unless the Bank shall otherwise
                                   ------
     elect, as cash collateral for any settlement of provisional credit; and (v)
     fifth, the excess, if any, shall be credited to the Borrower's
     -----

                                                                              50
<PAGE>

          operating account with the Bank. In the event that the Bank shall
          elect at any time not to apply the payment as contemplated by the
          foregoing clause (iv), such election shall not be deemed a waiver of
          the Bank's rights to apply payments pursuant to such clause at a later
          time, and the Bank shall be entitled to apply payments pursuant to
          such at such later time and from time to time thereafter.

(S)3. LETTERS OF CREDIT, BANKERS' ACCEPTANCES AND SUPPLEMENTAL FACILITIES.
      ------- -- ------  -------- ----------- --- ------------ ----------

(S)3.1. Letter of Credit Issuance. Subject to the terms and conditions hereof
        ------ -- ------ --------
and the execution and receipt of a Loan and Letter of Credit Request reflecting
the Maximum Drawing Amount of all Letters of Credit (including the requested
Letter of Credit) and a Letter of Credit Application at least four Business Days
prior to issuance, the Bank, in reliance upon the representations and warranties
of the Borrower contained herein, may, at its discretion, issue standby letters
of credit in such form as may be requested from time to time by the Borrower and
agreed to by the Bank (the "Letters of Credit"); provided, however, that, no
                                                 --------  -------
Letter of Credit shall have an expiration date later than the earlier of (i) one
year after the date of issuance of the Letter of Credit, or (ii) thirty (30)
days prior to the Maturity Date and provided further that, after giving effect
                                    -------- -------
to the requested Letter of Credit, the aggregate Maximum Drawing Amount of all
Letters of Credit issued hereunder shall not exceed $1,000,000.

(S)3.2. Bankers' Acceptance Facility. Subject to the terms and conditions set
        -------- ---------- --------
forth in this Agreement and the execution by the Borrower of an Acceptance
Agreement in the Bank's customary form, completed to the satisfaction of the
Bank with supporting documentation acceptable to the Bank (the "Acceptance
Agreement"), upon the written request of the Borrower at least three (3)
Business Days prior to the requested date of issuance, the Bank, in reliance
upon the representations and warranties of the Borrower contained herein, agrees
to issue Bankers' Acceptances for the account of the Borrower in a minimum face
amount of $500,000 in such form as the Borrower and the Bank may agree;
provided, however, that any Bankers' Acceptance issued shall provide for a
--------  -------
maturity date not later than 90 days from the date of issuance (but in no event
shall such maturity extend beyond the Maturity Date); and provided, further,
                                                          --------  -------
that the aggregate Acceptance Face Amount shall at no time exceed $4,000,000;
and provided, further, that, after giving effect to such request, the Total Loan
    --------  -------
Outstandings unpaid shall not exceed the lesser of the Loan Commitment or the
Borrowing Base; and provided, further, that the Bank shall not issue any
                    --------  -------
Bankers' Acceptance if the face amount of all outstanding drafts accepted by the
Bank which are of the type described in 12 U.S.C. (S)372, as amended from time
to time, or any successor statute, would cause the Bank to violate any
limitation imposed upon it under said statute or would cause the Bank to violate
such limitation if all such drafts were sold by the Bank in the secondary
market. Upon the satisfaction of the conditions set forth in (S)9 and (S)10
hereof, the Bank shall make available to the Borrower at the time of issuance of
each Bankers' Acceptance an amount equal to the amount requested, plus an amount
(computed on the basis of a year of three hundred sixty (360) days for the
actual days elapsed) equal to the sum of (a) the per annum average discount rate
quoted to the Bank on the day a request for a Bankers' Acceptance is presented
by the Bank's bankers' acceptance traders for acceptances which are of the type
described in 12 U.S.C. (S)372, as amended from time to time, or any successor
statute, and

                                                                              51

which approximate the face amount and mature on the maturity date requested plus
                                                                            ----
(b) one and three-quarters percent (1.75%) per annum (the "Bankers' Acceptance
Fee").

(S)3.3. Supplemental Commitment Facilities. In addition to making the Loans and
        ------------ ---------- ----------
issuing the Credit Instruments, and subject to the terms and conditions set
forth in this Agreement, the Bank agrees to fund payroll and other obligations
of the Borrower incurred pursuant to cash management services provided to the
Borrower by the Bank ("ACH Advances"), in an amount not to exceed $1,000,000 in
the aggregate at any one time and not to exceed more than $1,000,000 in any one
week, and to perform foreign exchange transactions on request of the Borrower in
accordance with documentation acceptable to the Bank, in amounts not to exceed
$500,000 in the aggregate at any one time, subject to a daily delivery limit of
$250,000 (the "Foreign Exchange Transactions" and, with the ACH Advances, the
"Supplement Commitment"), provided, however, that the Bank shall have no
                          --------  -------
obligation to make ACH Advances or to perform Foreign Exchange Transactions if
an Event of Default should occur, whether or not the Bank has accelerated the
Borrower's Obligations pursuant to (S)11 hereof.

to issue, extend and renew each Credit Instrument, to fund the ACH Advances and
to perform the Foreign Exchange Transactions, the Borrower hereby agrees to
reimburse or pay to the Bank with respect to each such facility as follows:

          (a) On each date that any draft presented under any Letter of Credit
     is honored by the Bank or the Bank otherwise makes payment with respect
     thereto, or, in the case of Bankers' Acceptances, on the maturity date of
     each such Bankers' Acceptance (i) the amount paid by the Bank under or with
     respect to such Letter of Credit, and, with respect to the Bankers'
     Acceptances, the amount of such Bankers' Acceptances then maturing and (ii)
     the charges or other costs and expenses whatsoever incurred by the Bank in
     connection with any payment made by the Bank under, or with respect to,
     such Credit Instrument.

          (b) Upon receipt of notice from the Bank that the Bank has made an ACH
     Advance, (i) the principal amount of such advance and (ii) the charges or
     any other costs and expenses whatsoever incurred by the Bank in connection
     with any payment made by the Bank in connection with such advance.

     with the documentation separately executed by the Borrower and the Bank.

          (d) Upon the reduction (but not termination) of the Total Loan
     Commitment to an amount less than the sum of the Maximum Drawing Amount,
     plus the Acceptance Face Amount, plus all unpaid Reimbursement Obligations,

     unpaid ACH Advance, plus 105% of any foreign exchange exposure
                         ----
     (collectively, the "Cash Collateral Amount"), which amount shall be held by
     the Bank as cash collateral for all Reimbursement Obligations.

          (f) Each such payment shall be made to the Bank in accordance with
     (S)4.2 hereof. Interest on any and all amounts remaining unpaid by the
     Borrower in respect of Reimbursement Obligations at any time from the date
     such amounts become due and payable (whether as stated in this (S)3.4, by
     acceleration or otherwise) until payment in full (whether before or after
     judgment) shall be payable to the Bank on demand at the rate specified in
     (S)2.7 for overdue amounts.

                                                                              53

        ------ -- ------ --------
demand for payment shall be made under any Letter of Credit, the Bank shall
notify the Borrower of the date and amount of the draft presented or demand for
payment and of the date and time when it expects to pay such draft or honor such
demand for payment. On the date that such draft is paid or other payment is made
by the Bank, the Bank shall promptly notify the Borrower of the amount of any
unpaid Reimbursement Obligation. All such unpaid Reimbursement Obligations with
respect to Letters of Credit shall be deemed to be Loans.

(S)3.6. Obligations Absolute. The Borrower's obligations under this (S)3 shall
        ----------- --------
be absolute and unconditional under any and all circumstances and irrespective
of the occurrence of any Default or Event of Default or any condition precedent
whatsoever or any setoff, counterclaim or defense to payment which the Borrower
may have or have had against the Bank or any beneficiary of a Credit Instrument.
The Borrower further agrees with the Bank that the Bank shall not be responsible
for, and the Borrower's Reimbursement Obligations under (S)3.4 shall not be
affected by, among other things, the validity or genuineness of documents or of
any endorsements thereon, even if such documents should in fact prove to be in
any or all respects invalid, fraudulent or forged, or any dispute between or
among the Borrower, the beneficiary of any Credit Instrument or any financing
institution or other party to which any Credit Instrument may be transferred or
any claims or defenses whatsoever of the Borrower, or against the beneficiary of
any Credit Instrument or any such transferee. The Bank 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 Credit
Instrument, ACH Advance or Foreign Currency Transaction. The Borrower agrees
that any action taken or omitted by the Bank under or in connection with each
Credit Instrument, ACH Advance or Foreign Currency Transaction and the related
drafts and documents, if done in good faith, shall be binding upon the Borrower
and shall not result in any liability on the part of the Bank to the Borrower.

(S)3.7. Reliance by Bank. To the extent not inconsistent with (S)3.6, the Bank
        -------- -- ----
shall be entitled to rely, and shall be fully protected in relying upon, any
Credit Instrument, 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 Bank.

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

(S)4.1.  Fees.
         ----

               (a) Commitment Fees. The Borrower agrees to pay commitment fees
                   ---------- ----
     at the rate of one-quarter percent (1/4%) per annum on the unused portion
     of the Loan Commitment during each calendar month or portion thereof from
     the Closing Date to the Maturity Date (or to the date of termination in
     full of the Total Commitment, if earlier) (the "Commitment Fee"). For
     purposes of computing the Commitment Fee, the Acceptance Face Amount shall
     be considered usage of the Total Loan Commitment. The Commitment Fee shall
     be payable on the Closing Date and in

                                                                              54
<PAGE>

     arrears on the first day of each calendar month for the immediately
     preceding month with a final payment on the Maturity Date.

          (b) Letter of Credit Fee. The Borrower shall pay a fee (the "Letter of
              ------ -- ------ ---
     Credit Fee") to the Bank equal to one percent (1%) per annum (pro-rated for
     the period for which such Letter of Credit shall remain outstanding) of the
     Maximum Drawing Amount of each Letter of Credit payable in advance on the
     date of issuance of the applicable Letter of Credit (but in no case less
     than $350.00), plus the Bank's customary issuance fee, payable in
                    ----
     accordance with the Bank's customary practice.

          (c) Collateral Management Fee. The Borrower agrees to pay a collateral
              ---------- ---------- ---
     management fee to the Bank in the amount of $600.00 per month, payable in
     advance on the first day of each month commencing with June 1999, for as
     long as any Obligations remain outstanding.

(S)4.2. Payments.
        --------

          (a) All payments of principal, interest, Bankers' Acceptance Fees,
     Commitment Fees, Collateral Management Fees and any other amounts due
     hereunder or under the Loan Documents shall be made by the Borrower to the
     Bank in immediately available funds at the Bank's office at 100 Federal
     Street, Boston, Massachusetts 02110. The Bank shall be entitled to debit
     the Borrower's operating account with the Bank in the amount of each such
     payment when due in order to effect timely payment thereof.

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

(S)4.3. Computations. All computations of interest on the Loans and of
        ------------
Commitment Fees shall be based on a 360-day year and paid for the actual number
of days elapsed including the first day, but excluding the last day. Whenever a
payment hereunder or under the Note becomes due on a day which is not a Business
Day, the due date for such payment shall be

                                                                              55
<PAGE>

extended to the next succeeding Business Day, and interest shall accrue during
such extension.

(S)4.4. Interest Limitation. Notwithstanding any other term of this Agreement or
        -------- ----------
the Note or any other document referred to herein or therein, the maximum amount
of interest which may be charged to or collected from the Borrower hereunder or
under any Note by the Bank shall be absolutely limited to, and shall in no event
exceed, the maximum amount of interest which could lawfully be charged or
collected under applicable law (including, to the extent applicable, the
provisions of Section 5197 of the Revised Statutes of the United States of
America, as amended, 12 U.S.C. Section 85, as amended), so that the maximum of
all amounts constituting interest under applicable law, howsoever computed,
shall never exceed such lawful maximum, and any term of this Agreement, the
Note, or any other document referred to herein or therein which could be
construed as providing for interest in excess of such lawful maximum shall be
and hereby is made expressly subject to and modified by the provisions of this
paragraph.

(S)4.5. Additional Costs, Etc. If any present or future applicable law, which
        ---------- -----  ---
expression, as used herein, includes statutes, rules and regulations thereunder
and interpretations thereof by any competent court or by any governmental or
other regulatory body or official charged with the administration or the
interpretation thereof and requests, directives, instructions and notices at any
time or from time to time hereafter made upon or otherwise issued to the Bank by
any central bank or other fiscal, monetary or other authority (whether or not
having the force of law), shall:

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

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

     (c) impose or increase or render applicable (other than to the extent
specifically provided for elsewhere in this 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 commitments of, an office of the Bank, or

     (d) impose on the Bank any other conditions or requirements with respect to
this Agreement, the other Loan Documents, the Loans, the Total Commitment, or
any class of loans or commitments of which any of the Loans or the Total
Commitment forms a part,

and the result of any of the foregoing is

         (i) to increase the cost to the Bank of making, funding, issuing,
     renewing, extending or maintaining the Loans, or the Total Commitment;

                                                                              56
<PAGE>

               (ii)  to reduce the amount of principal, interest or other amount
          payable to the Bank hereunder on account of the Total Commitment, or
          the Loans;

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

then, and in each such case, the Borrower will, upon demand made by the Bank at
any time and from time to time and as often as the occasion therefor may arise,
pay to the Bank such additional amounts as will be sufficient to compensate the
Bank for such additional cost, reduction, payment or foregone interest or other
sum (after the Bank shall have allocated the same fairly and equitably among all
customers of any class generally affected thereby).

(S)4.6. Capital Adequacy. If any present or future applicable law, governmental
        ------- --------
rule, regulation, policy, guideline or directive (whether or not having the
force of law) or the interpretation thereof by a court or governmental authority
with appropriate jurisdiction affects the amount of capital required or expected
to be maintained by the Bank or any corporation controlling the Bank and the
Bank determines that the amount of capital required to be maintained by it is
increased by or based upon the Bank's commitment to make, or maintenance of,
Loans hereunder, then the Bank may notify the Borrower of such fact. To the
extent that the costs of such increased capital requirements are not reflected
in the Base Rate, the Borrower and the Bank shall thereafter attempt to
negotiate in good faith, within thirty (30) days of the day on which the
Borrower receives such notice, an adjustment payable hereunder that will
adequately compensate the Bank in light of these circumstances. If the Borrower
and the Bank are unable to agree to such adjustment within thirty (30) days of
the date on which the Borrower receives such notice, then commencing on the date
of such notice (but not earlier than the effective date of any such increased
capital requirement), the fees payable hereunder shall increase by an amount
that will, in the Bank's reasonable determination, provide adequate compensation
to the Bank, such amount to be considered prima facie correct and binding,
absent manifest error. The Bank shall allocate such cost increases among its
customers in good faith and on an equitable basis.

(S)4.7. Eurodollar Indemnity. The Borrower agrees to indemnify the Bank and to
        ---------- ---------
hold it harmless from and against any loss, cost or expenses (including loss of
anticipated profits) that the Bank may sustain or incur as a consequence of
default by the Borrower in making a borrowing or conversion after the Borrower
has given (or is deemed to have given) notice pursuant to (S)2.5 or (S)2.6, the
making of any payment of a Eurodollar Loan or the making of any conversion of
any such Eurodollar 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 any bank to lenders of funds obtained by it in order to maintain
any such Loans.

(S)4.8. Illegality; Inability to Determine Eurodollar Rate. Notwithstanding any
        ----------  --------- -- --------- ---------- ----
other provision of this Agreement, if (a) the introduction of, any change in, or
any change in the interpretation of, any law or regulation applicable to the
Bank shall make it unlawful, or any central bank or other governmental authority
having jurisdiction thereof shall assert that it is unlawful, for the Bank to
perform its obligations in respect of any Eurodollar Loans, or

                                                                              57
<PAGE>

(b) if the Bank shall reasonably determine with respect to Eurodollar Loans that
(i) by reason of circumstances affecting any Eurodollar interbank market,
adequate and reasonable methods do not exist for ascertaining the Eurodollar
Rate which would otherwise be applicable during any Interest Period, or (ii)
deposits of Dollars in the relevant amount for the relevant Interest Period are
not available to the Bank in any Eurodollar interbank market, or (iii) the
Eurodollar Rate does not or will not accurately reflect the cost to the Bank of
obtaining or maintaining the applicable Eurodollar Loans during any Interest
Period, then the Bank shall promptly give telephonic, telex or cable notice of
such determination to the Borrower (which notice shall be conclusive and binding
upon the Borrower). Upon such notification by the Bank, the obligation of the
Bank to make Eurodollar Loans shall be suspended until the Bank determines that
such circumstances no longer exist, and the outstanding Eurodollar Loans shall
continue to bear interest at the applicable rate based on the Eurodollar Rate
until the end of the applicable Interest Period, and thereafter shall be deemed
converted to Base Rate Loans.

(S)5.18. Perfection of Security Interests. The Collateral and the Bank's rights
         ---------- -- -------- ---------
with respect to the Collateral are not subject to any setoff, claims,
withholdings or other defenses, except

                                                                              63

         then existing Default or Event of Default they shall disclose in such
         statement any such Default or Event of Default; provided, that the

               (c) as soon as practicable, but in any event not later than 45
         days after the end of each quarter of the Borrower's fiscal year, and

         in (b) above respecting the last month of each such quarter, a

               (e) not later than the fifteenth (15th) day of each month, (i) a
         certificate in the form of Exhibit C hereto (the "Borrowing Base
                                    ------- -
         Report"), setting forth the Borrowing Base as at the end of such month

Subsidiaries to, continue to engage primarily in the businesses now conducted by
them and in related businesses.

section shall prevent the Borrower from discontinuing the operation and
maintenance of any of its properties or those of its Subsidiaries if such

amount of the Borrower's insurance be less than the Total Commitment),
including, to the extent it is commercially available to the Borrower at a

on a consolidated basis) imposed upon it and its Real Properties, sales and
activities, or any part thereof, or upon the income or profits therefrom, as
well as all claims for labor, materials, or supplies, which if unpaid might by
law become a lien or charge upon any of its property; provided, however, that

any such tax, assessment, charge, levy or claim need not be paid if the validity
or amount thereof shall currently be contested in good faith by appropriate
proceedings and if the Borrower or such Subsidiary shall have set aside on its
books adequate reserves with respect thereto; and provided, further, that the
                                                  --------  -------

times and intervals as the Bank may reasonably request. For each day that the
Bank or its designated representative is conducting such inspection, the
Borrower shall pay an auditing charge of $650 per day plus expenses.

("Applicable Laws") except where noncompliance with such agreements, instruments
or Applicable Laws would not have a material adverse effect in the aggregate on
the financial condition, properties or business of the Borrower or any
Subsidiary. If at any time while the Note or any Loan is outstanding or the Bank
has any

                                                                              67

authorization, consent, approval, permit or license and furnish the Bank with
evidence thereof.

exceed the amount specified for such account on Schedule 6.13; any amounts in
excess of the amounts specified in Schedule 6.13 shall be immediately
transferred to the Depository Accounts.

(S)6.14. Environmental Indemnification. The Borrower covenants and agrees that
         ------------- ---------------

Property or the operations conducted thereon; or (c) the investigation or
remediation of offsite locations at which the Borrower or its Subsidiaries, or

         EPA Consent Order;

then, the Bank may by notice in writing to the Borrower declare all amounts
owing with respect to this Agreement, the Note, and the other Loan Documents,
and all Reimbursement Obligations to be, and they shall thereupon forthwith

the Borrower; provided, that in the event of any Event of Default specified in
              --------
(S)(S)11(g) or 11(h) hereof, all such amounts shall become immediately due

                                                                              79

Upon demand by the Bank after the occurrence of any Event of Default, the
Borrower shall immediately provide to the Bank cash in an amount equal to the
Cash Collateral Amount to be held by the Bank as collateral security for the
Obligations. In case any one or more of the Events of Default shall have
occurred and be continuing, and whether or not the Bank shall have accelerated
the maturity of the Loans pursuant to the foregoing, the Bank, if owed any
amount with respect to the Loans, may proceed to protect and enforce its rights
by suit in equity, action at law and/or other appropriate proceeding, whether
for the specific performance of any covenant or agreement contained in this
Agreement or any instrument pursuant to which the Obligations to the Bank
hereunder 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 the Bank. No remedy herein conferred upon the
Bank or the holder of the Note 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.

the Collateral, whether now owned or hereafter acquired, pursuant to the terms
of the Security Documents.

(S)13. SETOFF. Regardless of the adequacy of any collateral, during the
       ------
continuance of an Event of Default, any deposits or other sums credited by or
due from the Bank to the Borrower and any securities or other property of the
Borrower in the possession of the Bank may be applied to or set off against the
payment of the Obligations hereunder and under the Note and any and all other
liabilities, direct, or indirect, absolute or contingent, due or to become due,
now existing or hereafter arising, of the Borrower to the Bank.

(S)14. EXPENSES. Whether or not the transactions contemplated herein shall be
       --------
consummated, the Borrower hereby promises to reimburse the Bank for all
reasonable out-of-pocket attorneys' fees and disbursements incurred or expended
in connection with the preparation or interpretation of this Agreement, the
Note, or any other Loan Document or any amendment hereof or thereof, or with the
collection or enforcement of any Obligations or the satisfaction of any
indebtedness of the Borrower hereunder or thereunder, or in connection with any
litigation, proceeding or dispute in any forum, including without limitation
federal bankruptcy court, in any way related to the Loan Documents and the
credit extended hereunder, including without limitation the so-called "work-out"
thereof after the occurrence of a Default or Event of Default. The Borrower will
pay any taxes (including any interest and penalties in respect thereof), other
than the Bank's federal and state income taxes, payable on or with respect to
the transactions contemplated by this Agreement (the Borrower hereby agreeing to
indemnify the Bank with respect thereto).

(S)15. INDEMNIFICATION. The Borrower agrees to indemnify and hold harmless the
       ---------------
Bank, as well as the Bank's shareholders, directors, agents, officers,
subsidiaries and affiliates, from and against all damages, losses, settlement
payments, obligations, liabilities, claims, actions or causes of action, whether
statutorily created or under the common law, and

                                                                              80
<PAGE>

reasonable costs and expenses incurred, suffered, sustained or required to be
paid by an indemnified party by reason of or resulting from the transactions
contemplated hereby. In any investigation, proceeding or litigation, or the
preparation therefor, the Bank shall be entitled to select its own counsel and,
in addition to the foregoing indemnity, the Borrower agrees to pay promptly the
reasonable fees and expenses of such counsel. In the event of the commencement
of any such proceeding or litigation, the Borrower shall be entitled to
participate in such proceeding or litigation with counsel of its choice at its
expense, provided that such counsel shall be reasonably satisfactory to the
Bank. The covenants of this (S)15 shall survive payment or satisfaction in full
of amounts owing with respect to the Note or any other Loan Document.

(S)16. SURVIVAL OF COVENANTS, ETC. All covenants, agreements, representations
       -------- -- ---------  ---
and warranties made herein, in the other Loan Documents or in any documents or
other papers delivered by or on behalf of the Borrower pursuant hereto shall be
deemed to have been relied upon by the Bank, notwithstanding any investigation
heretofore or hereafter made by it, and shall survive the making by the Bank of
the Loans as herein contemplated, and shall continue in full force and effect so
long as any amount due under this Agreement or the Note remains outstanding and
unpaid or the Bank has any obligation to make any Loans hereunder. All
statements contained in any certificate or other paper delivered to the Bank at
any time by or on behalf of the Borrower pursuant hereto or in connection with
the transactions contemplated hereby shall constitute representations and

(S)17. SYNDICATION AND PARTICIPATION. It is understood and agreed that the Bank
       ----------- --- -------------
shall have the right, at any time after making Loans hereunder in excess of
$1,000,000, to syndicate or participate at any time any portion of the Total
Loan Commitment and interests in the risk relating to any Loans to additional
banks or other financial institutions so long as the Bank will be the agent bank
thereunder, and that each bank or other financial institution which executes and
delivers to the Bank and the Borrower hereunder a counterpart joinder in form
and substance satisfactory to the Bank and such bank or financial institution
shall, on the date specified in such counterpart joinder, become a party to this
Agreement and the other Loan Documents for all purposes of this Agreement and
the other Loan Documents, and its commitment amount shall be as set forth in
such counterpart joinder. Upon the execution and delivery of such counterpart
joinder, (a) the Borrower shall issue to the bank or other financial institution
a Note in the amount of such bank's or other financial institution's commitment
amount dated the Closing Date or such other date as may be specified by the Bank
and otherwise completed in substantially the form of Exhibit A; (b) this
Agreement shall be deemed to be amended to reflect the commitment amount and
interest in the risk related to Loans of such bank or other financial
institution and the Bank's portion of the Total Loan Commitment shall be reduced
by a like amount; (c) the Bank shall distribute to the Borrower and such bank or
financial institution a schedule reflecting such changes; and (d) this Agreement
shall be appropriately amended to reflect (i) the status of such bank or
financial institution as a party hereto and (ii) the status and rights of the
Bank as agent for itself and such other bank or financial institution hereunder.
The Bank shall also have the right to assign to, or grant participations to one
or more banks or other financial institutions in, all or any part of any Loan
owing to the Bank and the Note held by the Bank,

                                                                              81

provided that the only rights granted to the participant pursuant to such
--------
participation arrangements with respect to waivers, amendments, or modifications

principal of or rate of interest on or Commitment Fee with respect to the
portion of any Loan subject to such participation or assignment, (b) the

thereon. No course of dealing or delay or omission on the part of the Bank in
exercising any right shall operate as a waiver thereof or otherwise be
prejudicial thereto. No notice to or demand upon the Borrower shall entitle the
Borrower to other or further notice or demand in similar or other circumstances.

                                                                            84
