periods occurring or ending prior to January 1, 2000.

                              DESCRIPTION OF CREDIT
                              ---------------------

     2.1 Loans.
         -----

         (a)  Revolving Credit Loans. Upon the terms and subject to the
              conditions of this Agreement, and in reliance upon the
              representations, warranties and covenants of the Borrowers herein,
              each of the Lenders agrees, severally and not jointly, to make
              revolving credit loans (the "Revolving Credit Loans") to the
              Borrowers at NAC's request from time to time from and after the
              Closing Date and prior to the Maturity Date, provided that the
              Total Outstandings (after giving effect to all requested Revolving
              Credit Loans and Letters of Credit) shall not at any time exceed
              the lesser of (i) the Borrowing Base and (ii) the Total
              Commitment, and provided, further that the sum of the aggregate
              principal amount of outstanding Revolving Credit Loans made by
              each Lender and all outstanding Letter of Credit Participations of
              such Lender shall not at any time (after giving effect to all
              requested Revolving Credit Loans and Letters of Credit) exceed
              such Lender's Commitment. The Borrowers may borrow, repay, prepay
              and reborrow Revolving Credit Loans, up to the limits imposed by
              this Section 2.1, from time to time between the Closing Date and
              the Maturity Date upon request given by NAC to the Administrative
              Agent pursuant to Section 2.3. Each request for a Revolving Credit
              Loan or Letter of Credit hereunder shall constitute a
              representation and warranty by the Borrowers that the conditions
              set forth in Sections 3.1 and 3.2 have been satisfied as of the
              date of such request.

                                      -20-

         (b)  Limitations. No Eurodollar Loan shall be requested or made for
              less than a minimum of $1,000,000 in principal amount and in
              integral multiples of $100,000 in excess of such minimum amount
              and no Base Rate Loan shall be requested or made for less than a
              minimum of $50,000 in principal amount. No more than five
              Eurodollar Loans may be outstanding at any time.

         (c)  Conversion of Loans. Upon the terms and subject to the conditions
              of this Agreement, the Borrowers may convert all or any part (in
              integral multiples of $500,000) of any outstanding Loan of one
              Type into a Loan of another Type on any Business Day (which, in
              the case of a conversion of an outstanding Eurodollar Loan shall
              be the last day of the Interest Period applicable to such
              Eurodollar Loan). The Borrowers shall give the Administrative
              Agent prior notice of each such conversion (which notice shall be
              effective upon receipt) in accordance with Section 2.3.

         (d)  Termination or Reduction of Commitments. All Commitments shall
              terminate on the Maturity Date. Subject to the provisions of
              Section 2.7(c) regarding mandatory payments, the Borrowers shall
              have the right at any time and from time to time upon seven (7)
              days' prior written notice to the Administrative Agent to reduce
              by $1,000,000, and in integral multiples of $500,000 if in excess
              thereof, the Total Commitment or to terminate entirely the
              Lenders' Commitments to make Loans hereunder, whereupon the
              Commitments of the Lenders shall be reduced pro rata in accordance
              with their respective Commitment Percentages by the aggregate
              amount specified in such notice or shall, as the case may be, be
              terminated entirely. If, as a result of any such reduction of the
              Total Commitment, the Maximum Drawing Amount at the time would
              exceed the Total Commitment or the amount of Letters of Credit
              permitted to be outstanding under Sections 2.1(a) and 2A.1(a)
              hereof, the Borrowers shall, as a condition precedent to any such
              reduction, deposit with and pledge to the Administrative Agent for
              the benefit of the Lenders and the Issuing Bank cash in an amount
              equal to 105% of such excess. If any Letters of Credit would
              remain outstanding after the effective date of any such
              termination of the Total Commitment, in addition to satisfaction
              of all other applicable terms and conditions of this

                                                       -21-

              Agreement, the Borrowers shall deposit with and pledge to the
              Administrative Agent for the benefit of the Lenders and the
              Issuing Bank cash in an amount equal to 105% of the Maximum
              Drawing Amount at the effective date of such termination. No
              reduction or termination of any Commitment may be reinstated.

     2.2  The Notes. The Revolving Credit Loans shall be evidenced by separate
          promissory notes for each Lender in a principal amount equal to such
          Lender's Commitment, each such note to be substantially in the form of
          Exhibit A hereto, dated as of the Closing Date and completed with
          appropriate insertions (each such note being referred to herein as a
          "Revolving Credit Note" and collectively as the "Revolving Credit
          Notes"). The Borrowers irrevocably authorize each of the Lenders 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 the Notes, an appropriate notation on its Note Record
          reflecting (as the case may be) the making of such Loan or the receipt
          of such payment. The outstanding amount of the Loans set forth on the
          Note Records shall be prima facie evidence of the principal amount
          thereof owing and unpaid to such Lenders, but the failure to record,
          or any error in so recording, any such amount on any Lender's Note
          Record shall not limit or otherwise affect the obligations of the
          Borrowers hereunder or under any Note to make payments of principal of
          or interest on any Note when due.

     2.3  Notice and Manner of Borrowing or Conversion of Loans.
          -----------------------------------------------------

          (a) Whenever the Borrowers desire to obtain or continue a Loan
              hereunder or convert an outstanding Loan into a Loan of another
              Type, NAC shall give the Administrative Agent a written Notice of
              Borrowing or Conversion (or a telephonic notice promptly confirmed
              by a written Notice of Borrowing or Conversion), which Notice
              shall be irrevocable and which must be received no later than 3:00
              p.m. Boston time on the date (i) one Business Day before the day
              on which the requested Loan is to be made as or converted to a
              Base Rate Loan, and (ii) three Business Days before the day on
              which the requested Loan is to be made or continued as or
              converted to a Eurodollar Loan. Such Notice of Borrowing or
              Conversion shall specify (i) the effective date and amount of each
              Loan or portion thereof requested to be made, continued or
              converted, subject to the limitations

                                      -22-



              set forth in Section 2.1, (ii) the interest rate option requested
              to be applicable thereto, and (iii) the duration of the applicable
              Interest Period, if any (subject to the provisions of the
              definition of the term "Interest Period"). If such Notice fails to
              specify the interest rate option to be applicable to the requested
              Loan, then the Borrowers shall be deemed to have requested a Base
              Rate Loan. If the written confirmation of any telephonic
              notification differs in any material respect from the action taken
              by the Administrative Agent, the records of the Administrative
              Agent shall control absent manifest error.

          (b) Subject to the provisions of the definition of the term "Interest
              Period" herein, the duration of each Interest Period for a
              Eurodollar Loan shall be as specified in the applicable Notice of
              Borrowing or Conversion. If no Interest Period is specified in a
              Notice of Borrowing or Conversion with respect to a requested
              Eurodollar Loan, then the Borrowers shall be deemed to have
              selected an Interest Period of one month's duration. If the
              Administrative Agent receives a Notice of Borrowing or Conversion
              after the time specified in subsection (a) above, such Notice
              shall not be effective. If the Administrative Agent does not
              receive an effective Notice of Borrowing or Conversion with
              respect to an outstanding Eurodollar Loan, or if, when such Notice
              must be given prior to the end of the Interest Period applicable
              to such outstanding Loan, the Borrowers shall have failed to
              satisfy any of the conditions hereof, the Borrowers shall be
              deemed to have elected to convert such outstanding Loan in whole
              into a Base Rate Loan on the last day of the then current Interest
              Period with respect thereto.

     2.4  Funding of Loans.
          ----------------

          (a) Loans shall be made by the Lenders pro rata in accordance with
              their respective Commitment Percentages, provided, however, that
              the failure of any Lender to make any Loan shall not relieve any
              other Lender of its obligation to lend hereunder (it being
              understood, however, that no Lender shall be responsible for the
              failure of any other Lender to make any Loan required to be made
              by such other Lender).

                                      -23-

          (b) Each of the Lenders authorizes the Administrative Agent to advance
              all Revolving Credit Loans which are requested by the Borrowers
              during any calendar week, subject to the terms and conditions of
              this Agreement. On such day or days as the Administrative Agent
              shall designate, but at least once per week (each such day being
              referred to herein as a "Settlement Date"), whether or not the
              Commitments have been terminated, a Default has occurred, the
              Obligations have been accelerated or the Administrative Agent is
              proceeding to liquidate the Collateral, the Administrative Agent
              shall, as promptly as practicable during normal business hours,
              effect a wire transfer of immediately available funds to each
              Lender of the amount, if any, payable to such Lender, or each
              Lender shall transfer to the Administrative Agent sufficient
              immediately available federal funds to reimburse the
              Administrative Agent for each such Lender's pro rata share of all
              Revolving Credit Loans made by the Administrative Agent since the
              previous Settlement Date, in each case after taking into account
              payments and collections received by the Administrative Agent and
              applied to the Revolving Credit Loans, so that after giving effect
              to such transfers by the Administrative Agent to the Lenders or by
              the Lenders to the Administrative Agent, as the case may be, the
              Administrative Agent's Note Record shall correctly reflect each
              Lender's pro rata share of outstanding Revolving Credit Loans. All
              Revolving Credit Loans made by the Administrative Agent on behalf
              of the Lenders (including Revolving Credit Loans representing
              unpaid Reimbursement Obligations) shall be, for purposes of
              interest income and charges, considered to be Revolving Credit
              Loans from such Lenders to the Borrowers and reflected in the Note
              Records of the Administrative Agent and the Lenders (as among the
              Administrative Agent and the Lenders) at such time as the
              Administrative Agent receives from such Lenders funds as provided
              in this Section 2.4, and prior to such time such Revolving Credit
              Loans shall be considered, for purposes of interest income and
              other charges, to be Revolving Credit Loans from the
              Administrative Agent and so reflected in the Note Record of the
              Administrative Agent.

          (c) The Administrative Agent may notify the Lenders of any requested
              Loan and of the Drawdown Date thereof and the amount of each
              Lender's pro rata

                                      -24-

              share of such Loan, and not later than 1:00 p.m. (Boston time) on
              the proposed Drawdown Date of such Loan, each Lender will make
              available to the Administrative Agent, at its head office, in
              immediately available funds, the amount of such Lender's
              Commitment Percentage of the amount of such requested Loan. Upon
              receipt by the Administrative Agent of such amount, and upon
              receipt of the documents required by Section 3 and the
              satisfaction of the other conditions set forth therein (to the
              extent applicable), the Administrative Agent will make available
              to the Borrowers the aggregate amount of such Loan. The
              Administrative Agent may, unless notified to the contrary by any
              Lender prior to a Drawdown Date, assume that each Lender has made
              available to the Administrative Agent on such Drawdown Date the
              amount of such Lender's Commitment Percentage of the 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
              (i) the average, computed for the period referred to in clause
              (iii) 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 (ii) the amount of such Lender's Commitment Percentage of
              any such Loans times (iii) a fraction, the numerator of which is
              the number of days that elapse from and including such Drawdown
              Date to the date on which the amount of such Lender's Commitment
              Percentage of such Loans shall become immediately available to the
              Administrative Agent, and the denominator of which is 365. 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 Loans is not made available
              to the Administrative Agent by such Lender with 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
              Loans made on such Drawdown Date.

                                      -25-


          (d) The failure or refusal of any Lender to make available to the
              Administrative Agent at the aforesaid time and place on any
              Settlement Date or Drawdown Date the amount of its Commitment
              Percentage of any 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 Loans.

     2.5  Interest Rates and Payments of Interest.
          ---------------------------------------

          (a) Base Rate Loans. Each Loan which is a Base Rate Loan shall bear
              interest on the outstanding principal amount thereof at a rate per
              annum equal to the Alternate Base Rate plus the Applicable Margin,
              which rate shall change contemporaneously with any change in the
              Alternate Base Rate or the Applicable Margin, as provided below.
              Such interest shall be payable monthly in arrears on the first
              Business Day of each month, commencing February 1, 1999.

          (b) Eurodollar Loans. Each Loan which is a Eurodollar Loan shall bear
              interest on the outstanding principal amount thereof, for each
              Interest Period applicable thereto, at a rate per annum equal to
              the Eurodollar Rate plus the Applicable Margin, which rate shall
              change with any change in the Applicable Margin, as provided
              below. Such interest shall be payable for such Interest Period on
              the last day thereof and, if such Interest Period is longer than
              three months, at intervals of three months after the first day
              thereof.

          (c) Default Interest. If an Event of Default shall occur, then at the
              option of the Administrative Agent or the direction of the
              Majority Lenders the unpaid balance of Loans shall bear interest
              at an interest rate equal to 2% per annum above the interest rate
              applicable to Base Rate Loans in effect on the day such Event of
              Default occurs, until such Event of Default is cured or waived.

          (d) Applicable Margin. The Applicable Margin and the Interest Coverage
              Ratio shall be determined as of the end of each fiscal month based
              upon the monthly financial statements to be delivered pursuant to
              Section 5.1(b) hereof, and any change in the Applicable Margin
              shall be effective upon the earlier of (i) the delivery of such
              financial

                                      -26-

              statements, and (ii) the date such financial statements were due
              to be delivered pursuant to Section 5.1(b). Notwithstanding the
              foregoing, during the period from the Closing Date through and
              including December 31, 1999, the Applicable Margin shall be fixed
              at (i) 2.25% for Eurodollar Loans and Letter of Credit Fees, and
              (ii) 0.75% for Base Rate Loans.

          (e) Additional Interest. So long as any Lender shall be required under
              regulations of the Board of Governors of the Federal Reserve
              System (or any other banking authority, domestic or foreign, to
              which such Lender is subject) to maintain reserves with respect to
              liabilities or assets consisting of or including "Eurocurrency
              Liabilities" (as defined in regulations issued from time to time
              by such Board of Governors), the Borrowers shall pay to the
              Administrative Agent for the account of each such Lender
              additional interest on the unpaid principal amount of each
              Eurodollar Loan made by such Lender from the date of such Loan
              until such principal amount is paid in full, at an interest rate
              per annum equal at all times to the remainder (rounded upwards, if
              necessary, to the next higher 1/100 of 1%) obtained by subtracting
              (i) the Eurodollar Rate for the Interest Period for such
              Eurodollar Loan from (ii) the rate obtained by dividing such
              Eurodollar Rate by a percentage equal to 100% minus the Eurodollar
              Reserve Percentage of such Lender for such Interest Period. Such
              additional interest shall be determined by such Lender and
              notified to the Borrowers through the Administrative Agent, and
              shall be payable on each date on which interest is payable on such
              Eurodollar Loan.

     2.6  Fees.
          ----

          (a) The Borrowers shall pay to the Administrative Agent for the
              benefit of the Lenders a commitment fee (the "Commitment Fee"),
              computed on a daily basis and payable quarterly in arrears on the
              first Business Day of each calendar quarter, equal to one-half of
              one percent (0.50%) per annum of the excess of (i) the Total
              Commitment at the time over (ii) the Total Outstandings at the
              time.

          (b) The Borrowers shall pay to the Administrative Agent for the
              benefit of the Lenders a fee (the "Letter of Credit Fee") at a
              rate per annum equal to (i) the Maximum Drawing Amount of each
              Letter

                                      -27-

              of Credit multiplied by (ii) the Applicable Margin. In addition,
              the Borrowers shall pay to the Issuing Bank, solely for its own
              account, a fee (the "Fronting Fee") at a rate per annum equal to
              one-quarter of one percent (0.25%) of the Maximum Drawing Amount
              of each Letter of Credit. At the option of the Administrative
              Agent or the direction of the Majority Lenders the Letter of
              Credit Fees and Fronting Fees payable during the continuance of
              any Event of Default shall be equal to two percent (2%) per annum
              above the Letter of Credit Fee and Fronting Fee applicable to each
              Letter of Credit in effect on the day such Event of Default
              occurs, until such Event of Default is cured or waived. Letter of
              Credit Fees and Fronting Fees shall be payable quarterly in
              arrears on the first Business Day of each calendar quarter.

          (c) Without limiting any of the Lenders' other rights hereunder or by
              law, if any Loan or any portion thereof or any interest thereon or
              any other amount payable hereunder or under any other Loan
              Document is not paid within ten Business Days after its due date,
              the Borrowers shall pay to the Administrative Agent for the
              benefit of the Lenders on demand a late payment charge equal to
              2-1/2% of the amount of the payment due.

          (d) The Borrowers shall pay to the Administrative Agent, solely for
              the account of the Administrative Agent, such other fees as the
              Borrowers and the Administrative Agent shall agree.

          (e) The Borrowers authorize the Administrative Agent, the Issuing Bank
              and the Lenders to charge (no such charge shall be deemed to be a
              set-off) to their Note Records or to any deposit account which the
              Borrowers may maintain with any of them the interest, fees,
              charges, taxes and expenses provided for in this Agreement, the
              Security Documents or any other document executed or delivered in
              connection herewith.

     2.7  Payments and Prepayments of the Loans.
          -------------------------------------

          (a) On the Maturity Date, the Borrowers shall pay in full the unpaid
              principal balance of the Revolving Credit Loans, together with all
              unpaid interest thereon and all Fees and other amounts due with
              respect thereto.

                                      -28-

          (b) Loans that are Eurodollar Loans may be prepaid, without premium or
              penalty, on the last day of any Interest Period applicable
              thereto, upon three Business Days' notice. Loans that are Base
              Rate Loans may be prepaid at any time, without premium or penalty,
              upon one Business Day's notice. Any such notice of prepayment
              shall be irrevocable. Prepayments of Revolving Credit Loans may be
              reborrowed to the extent provided in Section 2.1.

          (c) If at any time the Total Outstandings exceed the lesser of (x) the
              Borrowing Base and (y) the Total Commitment, the Borrowers shall
              immediately pay the amount of any such excess to the
              Administrative Agent for application to the Revolving Credit
              Loans.

     2.8  Method and Allocation of Payments.
          ---------------------------------

          (a) All payments by the Borrowers 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 Borrowers are 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 each Lender
              such additional amount in U.S. Dollars as shall be necessary to
              enable such Lender to receive the same net amount which such
              Lender would have received on such due date had no such obligation
              been imposed upon the Borrowers. The Borrowers will deliver
              promptly to each Lender certificates or other valid vouchers or
              other evidence of payment reasonably satisfactory to the
              Administrative Agent 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. The Lenders may, and the
              Borrowers hereby authorize the Lenders to, debit the amount of any
              payment not made by such time to the demand deposit accounts of
              the Borrowers with the Lenders or to their Note Records.

                                      -29-

          (b) All payments of principal of and interest in respect of Loans
              shall be made to the Administrative Agent, for the benefit of the
              Lenders, pro rata in accordance with their Commitment Percentages,
              and payment of any other amounts due hereunder shall be made to
              the Administrative Agent for the benefit of the Lenders, pro rata
              as their respective interests appear, at the Administrative
              Agent's head office or at such other location that the
              Administrative Agent may from time to time designate, in each case
              in immediately available funds.

          (c) If the Commitments shall have been terminated or the Obligations
              shall have been declared immediately due and payable pursuant to
              Section 8.2, all funds received from or on behalf of the Borrowers
              (including as proceeds of Collateral) by any Lender or the Issuing
              Bank in respect of Obligations (except funds received by any
              Lender as a result of a purchase of a participant interest
              pursuant to Section 2.8(d) below) shall be remitted to the
              Administrative Agent, and all such funds, together with all other
              funds received by the Administrative Agent from or on behalf of
              the Borrowers (including proceeds of Collateral) in respect of
              Obligations, shall be applied by the Administrative Agent in the
              following manner and order: (i) first, to reimburse the
              Administrative Agent, the Issuing Bank and the Lenders, in that
              order, for any amounts payable pursuant to Sections 11.2 and 11.3
              hereof; (ii) second, to the payment of the Fees; (iii) third, to
              the payment of interest due on the Loans and the Reimbursement
              Obligations; (iv) fourth, to the payment of the outstanding
              principal balance of the Loans and the Reimbursement Obligations;
              (v) fifth, to the payment of any other Obligations (other than
              principal of or interest on the Loans, the Notes and the
              Reimbursement Obligations) payable by the Borrowers; and (vi) any
              remaining funds shall be paid to whoever shall be entitled thereto
              or as a court of competent jurisdiction shall direct.

          (d) Each of the Lenders and the Administrative Agent hereby agrees
              that if it should receive any amount (whether by voluntary
              payment, by realization upon security, by the exercise of the
              right of set-off or banker's lien, by counterclaim or cross
              action, by the enforcement of any right under the Loan Documents,
              or otherwise) in respect of principal of, or interest on, the
              Loans or any Fees which

                                      -30-

              are to be shared pro rata among the Lenders, which, as compared to
              the amounts theretofore received by the other Lenders with respect
              to such principal, interest or Fees, is in excess of such Lender's
              Commitment Percentage of such principal, interest or Fees, such
              Lender shall share such excess, less the costs and expenses
              (including, reasonable Attorneys' Fees and disbursements) incurred
              by such Lender in connection with such realization, exercise,
              claim or action, pro rata with all other Lenders in proportion to
              their respective Commitment Percentages, and such sharing shall be
              deemed a purchase (without recourse) by such sharing party of
              participant interests in the Loans or such Fees, as the case may
              be, owed to the recipients of such shared payments to the extent
              of such shared payments; provided, however, that if all or any
              portion of such excess amount is thereafter recovered from such
              Lender, such purchase shall be rescinded and the purchase price
              restored to the extent of such recovery, but without interest.

     2.9  Eurodollar Indemnity. If the Borrowers for any reason (including,
          without limitation, pursuant to Sections 2.7(c), 2.11 and 8.2 hereof)
          make any payment of principal with respect to any Eurodollar Loan on
          any day other than the last day of an Interest Period applicable to
          such Eurodollar Loan, or fail to borrow or continue or convert to a
          Eurodollar Loan after giving a Notice of Borrowing or Conversion
          thereof pursuant to Section 2.3, or fail to prepay a Eurodollar Loan
          after having given notice thereof, the Borrowers shall pay to the
          Administrative Agent for the benefit of the Lenders any amount
          required to compensate the Lenders for any additional losses, costs or
          expenses which they may reasonably incur as a result of such payment
          or failure, including, without limitation, any loss (including loss of
          anticipated profits), costs or expense incurred by reason of the
          liquidation or re- employment of deposits or other funds required by
          the Lenders to fund or maintain such Eurodollar Loan. The Borrowers
          shall pay such amount upon presentation by the Administrative Agent of
          a statement setting forth the amount and the Administrative Agent's
          (or the affected Lenders') calculation thereof pursuant hereto, which
          statement shall be deemed true and correct absent manifest error.

     2.10 Computation of Interest and Fees. Interest and all Fees payable
          hereunder shall be computed daily on the basis of a year of 365 days
          for Base Rate Loans and 360

                                      -31-

          days for all other Loans and Fees paid for the actual number of days
          for which due. If the due date for any payment of principal is
          extended by operation of law, interest shall be payable for such
          extended time. If any payment required by this Agreement becomes due
          on a day that is not a Business Day such payment may be made on the
          next succeeding Business Day (subject to the definition of the term
          "Interest Period"), and such extension shall be included in computing
          interest in connection with such payment.

     2.11 Changed Circumstances; Illegality.
          ---------------------------------

          (a)  Notwithstanding any other provision of this Agreement, in the
               event that:

               (i)  on any date on which the Eurodollar Rate would otherwise be
                    set the Administrative Agent shall have determined in good
                    faith (which determination shall be final and conclusive)
                    that adequate and fair means do not exist for ascertaining
                    the Eurodollar Rate, or

               (ii) at any time the Administrative Agent or any Lender shall
                    have determined in good faith (which determination shall be
                    final and conclusive and, if made by any Lender, shall have
                    been communicated to the Administrative Agent in writing)
                    that:

          (A) the making or continuation of or conversion of any Loan to a
     Eurodollar Loan has been made impracticable or unlawful by (1) the
     occurrence of a contingency that materially and adversely affects the
     interbank Eurodollar market or (2) compliance by the Administrative Agent
     or such Lender in good faith with any applicable law or governmental
     regulation, guideline or order or interpretation or change thereof by any
     governmental authority charged with the interpretation or administration
     thereof or with any request or directive of any such governmental authority
     (whether or not having the force of law); or

          (B) the Eurodollar Rate shall no longer represent the effective cost
     to the Administrative Agent or such Lender for U.S. dollar deposits in the
     interbank market for deposits in which it regularly participates;

then, and in any such event, the Administrative Agent shall forthwith so notify
the Borrowers thereof. Until the Administrative Agent notifies the Borrowers
that the circumstances giving rise to such notice no longer apply, the

                                      -32-

obligation of the Lenders to allow selection by the Borrowers of the Type of
Loan affected by the contingencies described in this Section (herein called
"Affected Loans") shall be suspended. If, at the time the Administrative Agent
so notifies the Borrowers, the Borrowers have previously given the
Administrative Agent a Notice of Borrowing or Conversion with respect to one or
more Affected Loans but such Loans have not yet gone into effect, such
notification shall be deemed to be a request for Base Rate Loans.

          (b)  In the event of a determination of illegality pursuant to
               subsection (a)(ii)(A) above, the Borrowers shall, with respect to
               the outstanding Affected Loans, prepay the same, together with
               interest thereon and any amounts required to be paid pursuant to
               Section 2.9, on such date as shall be specified in such notice
               (which shall not be earlier than the date such notice is given)
               and may, subject to the conditions of this Agreement, borrow a
               Loan of another Type in accordance with Section 2.1 hereof by
               giving a Notice of Borrowing or Conversion pursuant to Section
               2.3 hereof.

     2.12 Increased Costs. In case any change in law, regulation, treaty or
          official directive or the interpretation or application thereof by any
          court or by any governmental authority charged with the administration
          thereof or the compliance with any guideline or request of any central
          bank or other governmental authority (whether or not having the force
          of law):

                (i) subjects any Lender to any tax with respect to payments of
                    principal or interest or any other amounts payable hereunder
                    by the Borrowers or otherwise with respect to the
                    transactions contemplated hereby (except for taxes on the
                    overall net income of such Lender imposed by the United
                    States of America or any political subdivision thereof), or

               (ii) imposes, modifies or deems applicable any deposit insurance,
                    reserve, special deposit or similar requirement against
                    assets held by, or deposits in or for the account of, or
                    loans by, any Lender (other than such requirements as are
                    already included in the determination of the Eurodollar
                    Rate), or

              (iii) imposes upon any Lender any other condition with respect to
                    its obligations or

                                      -33-

                    performance under this Agreement or in respect of any Letter
                    of Credit,

and the result of any of the foregoing is to increase the cost to the Lender,
reduce the income receivable by such Lender or impose any expense upon such
Lender with respect to any Loans or its obligations under this Agreement or in
respect of any Letter of Credit, such Lender shall notify the Borrowers and the
Administrative Agent thereof. The Borrowers agree to pay to such Lender the
amount of such increase in cost, reduction in income or additional expense as
and when such cost, reduction or expense is incurred or determined, upon
presentation by such Lender of a statement in the amount and setting forth in
reasonable detail such Lender's calculation thereof and the assumptions upon
which such calculation was based, which statement shall be deemed true and
correct absent manifest error.

     2.13 Capital Requirements. If after the date hereof any Lender determines
          that (i) the adoption of or change in any law, rule, regulation or
          guideline regarding capital requirements for banks or bank holding
          companies, or any change in the interpretation or application thereof
          by any governmental authority charged with the administration thereof,
          or (ii) compliance by such Lender or its parent bank holding company
          with any guideline, request or directive of any such entity regarding
          capital adequacy (whether or not having the force of law), has the
          effect of reducing the return on such Lender's or such holding
          company's capital as a consequence of such Lender's Commitment to make
          Loans hereunder or its obligations in respect of any Letter of Credit
          to a level below that which such Lender or such holding company could
          have achieved but for such adoption, change or compliance (taking into
          consideration such Lender's or such holding company's then existing
          policies with respect to capital adequacy and assuming the full
          utilization of such entity's capital) by any amount deemed by such
          Lender to be material, then such Lender shall notify the Borrowers and
          the Administrative Agent thereof. The Borrowers agree to pay to such
          Lender the amount of such reduction of return on capital as and when
          such reduction is determined, payable within 90 days after
          presentation by such Lender of a statement in the amount and setting
          forth in reasonable detail such Lender's calculation thereof and the
          assumptions upon which such calculation was based (which statement
          shall be deemed true and correct absent manifest error) unless within
          such 90 day period the Borrowers shall have prepaid in full all
          Obligations to such Lender, in which event no amount shall be payable
          to such Lender under this Section. In determining such amount, such

                                      -34-

          Lender may use any reasonable averaging and attribution methods.

     2.14 Borrowers' Representatives. Each Borrower (other than NAC) hereby
          appoints NAC as its agent with respect to the receiving and giving of
          any notices, requests, instructions, reports, schedules, revisions,
          financial statements or any other written or oral communications
          hereunder. NAC shall keep complete, correct and accurate records of
          all Loans and the application of proceeds thereof, all Letters of
          Credit and all payments in respect of Loans and other amounts due
          hereunder. NAC shall determine the allocation of proceeds of Loans
          among the Borrowers. The Lenders are hereby entitled to rely on any
          communication given or transmitted by NAC as if such communication
          were given or transmitted by each and every Borrowers; provided,
          however, that any communication given or transmitted by any Borrowers
          other than NAC shall be binding with respect to such Borrowers. Any
          communication given or transmitted by the Administrative Agent, any
          Lender or the Issuing Bank to NAC shall be deemed given and
          transmitted to each and every Borrower. Notwithstanding the foregoing,
          all Obligations of the Borrowers hereunder shall be joint and several.


                                   SECTION IIA

                                LETTERS OF CREDIT
                                -----------------

     2A.1 Issuance.
          --------

          (a) Upon the terms and subject to the conditions hereof, the Issuing
Bank, in reliance upon the representations and warranties of the Borrowers
contained herein, agrees to issue letters of credit (the "Letters of Credit")
for the account of the Borrowers in such form as may be requested from time to
time by the Borrowers and agreed to by the Issuing Bank, provided that the
Maximum Drawing Amount (after giving effect to all requested Letters of Credit)
shall not at any time exceed the Letter of Credit Sublimit, provided, further,
that the Total Outstandings (after giving effect to all requested Revolving
Credit Loans and Letters of Credit) shall not at any time exceed the lesser of
(x) the Borrowing Base and (y) the Total Commitment, and provided, further, that
no Letter of Credit shall have an expiration date later than the Maturity Date.
At least three (3) Business Days prior to the proposed issuance date of any
Letter of Credit, the Borrowers shall deliver to the Issuing Bank a Letter of
Credit Application setting forth the Maximum Drawing Amount of all

                                      -35-

Letters of Credit (including the requested Letter of Credit), the requested
language of the requested Letter of Credit and such other information as the
Issuing Bank shall require. Each request for the issuance of a Letter of Credit
hereunder shall constitute a representation and warranty by the Borrowers that
the conditions set forth in Sections 3.1 and 3.2 have been satisfied as of the
date of such request. The Administrative Agent or the Issuing Bank shall notify
the Lenders of the issuance of each Letter of Credit and shall furnish to any
Lender such information with respect thereto as such Lender shall reasonably
request.

     (b) Effective upon the issuance of each Letter of Credit in accordance with
the terms hereof, and without any further action on the part of the Issuing Bank
or the Lenders in respect thereof, the Issuing Bank hereby grants to each
Lender, and each Lender hereby acquires from the Issuing Bank, a participating
interest in such Letter of Credit to the extent of such Lender's Commitment
Percentage thereof (the "Letter of Credit Participation"), and each Lender
severally agrees that it shall be absolutely liable, without regard to the
occurrence of any Default or Event of Default, to the extent of such Lender's
Commitment Percentage thereof, to reimburse the Issuing Bank on demand for the
amount of each draft paid by the Issuing Bank under each Letter of Credit to the
extent that such amount is not reimbursed by the Borrowers.

     2A.2 Reimbursement Obligation of the Borrowers. In order to induce the
Issuing Bank to issue, extend and renew each Letter of Credit, the Borrowers
hereby agree to reimburse or pay to the Issuing Bank, for the account of the
Issuing Bank or (as the case may be) the Lenders, with respect to each Letter of
Credit issued, extended or renewed by the Issuing Bank hereunder as follows:

     (a) on each date that any draft presented under any Letter of Credit is
honored by the Issuing Bank or the Issuing Bank otherwise makes payment with
respect thereto, (i) the amount paid by the Issuing Bank 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 Issuing Bank or any Lender
in connection with any payment made by the Issuing Bank under, or with respect
to, such Letter of Credit; and

     (b) upon the Maturity Date or the acceleration of the Reimbursement
Obligations pursuant to Section 8, an amount equal to 105% of the then Maximum
Drawing Amount of all Letters of Credit, which amount (together with all
interest and other earnings thereon) shall be held by the Issuing Bank as cash
collateral for all Reimbursement Obligations.

                                      -36-

Each such payment shall be made to the Issuing Bank at its head office in
immediately available funds. Interest on any and all amounts remaining unpaid by
the Borrowers under this Section 2A.2 at any time from the date such amounts
become due and payable (whether as stated in this Section 2A.2, by acceleration
or otherwise) until payment in full (whether before or after judgment) shall be
payable to the Issuing Bank, for the account of the Issuing Bank or (as the case
may be) the Lenders, on demand at a rate per annum equal to 2% above the
Interest Rate applicable to Base Rate Loans at the time in the absence of an
Event of Default.

     2A.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 Issuing Bank
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. The responsibility of the Issuing Bank to the
Borrowers shall be only to determine that the documents (including each draft)
delivered under each Letter of Credit in connection with such presentment shall
be in conformity in all material respects with such Letter of Credit. On the
date that such draft is paid or other payment is made by the Issuing Bank, the
Issuing Bank shall promptly notify the Lenders of the amount of any unpaid
Reimbursement Obligation. All such unpaid Reimbursement Obligations with respect
to Letters of Credit shall be deemed to be Revolving Credit Loans. No later than
1:00 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 head office, in immediately available funds, such
Lender's Commitment Percentage of such unpaid Reimbursement Obligation, together
with an amount equal to the product of (i) the average, computed for the period
referred to in clause (iii) below, of the weighted average interest rate paid by
the Administrative Agent for federal funds acquired by the Administrative Agent
during each day included in such period, times (ii) the amount equal to such
Lender's Commitment Percentage of such unpaid Reimbursement Obligation, times
(iii) a fraction, the numerator of which is the number of days that have elapsed
from and including the date the Issuing Bank paid the draft presented for honor
or otherwise made payment until 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 365.

     2A.4 Obligations Absolute.
          --------------------

          (a) The Borrowers' Reimbursement Obligations 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
set off,

                                      -37-

counterclaim or defense to payment which the Borrowers may have or have had
against the Issuing Bank, the Administrative Agent, the Lenders or any
beneficiary of a Letter of Credit. The Borrowers further agree that the Issuing
Bank, the Administrative Agent and the Lenders shall not be responsible for, and
the Borrowers' Reimbursement Obligations 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 Borrowers,
the beneficiary of any Letter of Credit or any financing institution or other
party to which any Letter of Credit may be transferred or any claims or defenses
whatsoever of the Borrowers, against the beneficiary of any Letter of Credit or
any such transferee.

          (b) The Issuing Bank, the Administrative Agent 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 Issuing Bank, the Administrative Agent or the Lenders 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 Issuing Bank, the Administrative Agent or
the Lenders to the Borrowers.

     2A.5 Reliance by the Issuing Bank and the Administrative Agent. To the
extent not inconsistent with Section 2A.4, the Issuing Bank and the
Administrative Agent shall be entitled to rely, and shall be fully protected in
relying upon, any Letter of Credit, draft writing, resolution, notice, consent,
certificate, affidavit, letter, cablegram, telegram, telecopy, telex or teletype
message, statement, order or other document believed by it to be genuine and
correct and to have been signed, sent or made by the proper Person or Persons
and upon advice and statements of legal counsel, independent accountants and
other experts selected with reasonable care by the Issuing Bank or the
Administrative Agent.

                                       IV.

                         REPRESENTATIONS AND WARRANTIES
                         ------------------------------

     In order to induce the Administrative Agent, the Issuing Bank and the
Lenders to enter into this Agreement and to make Loans and to issue Letters of
Credit hereunder, the Borrowers represent and warrant to the Administrative
Agent, the Issuing Bank and the Lenders that except as set forth on Exhibit C
attached hereto:

                                      -42-

     4.1  Organization; Qualification; Business.
          -------------------------------------

          (a)  Each of the Borrowers (i) is a corporation or limited liability
               company duly organized and validly existing under the laws of its
               jurisdiction of incorporation or organization, (ii) has all
               requisite corporate or other power to own its property and
               conduct its business as now conducted and as presently
               contemplated and (iii) is duly qualified and in good standing as
               a foreign corporation or limited liability company and is duly
               authorized to do business in each jurisdiction (all of which are
               listed on Exhibit C attached hereto) where the nature of its
               properties or business requires such qualification, except where
               the failure to be so qualified would not have a material adverse
               effect on the business, financial condition, assets or properties
               of any of the Borrowers or of the Borrowers taken as a whole.

          (b)  Since the date of the Initial Financial Statements, the Borrowers
               have continued to engage in substantially the same business as
               that in which they were then engaged and are not engaged in any
               business not reasonably related or ancillary thereto (as
               determined in good faith by GNA's Board of Directors).

     4.2  Corporate Authority. The execution, delivery and performance of the
          Loan Documents and the transactions contemplated thereby are within
          the corporate or other power and authority of the Borrowers, have been
          authorized by all necessary or other corporate action, and do not and
          will not (a) contravene any provision of the Articles or Certificate
          of Incorporation, by-laws or operating agreement, as applicable, of
          any of the Borrowers or any law, rule or regulation applicable to any
          of the Borrowers, (b) contravene any provision of, or constitute an
          event of default or event that, but for the requirement that time
          elapse or notice be given, or both, would constitute an event of
          default under, any other agreement, instrument, order or undertaking
          binding on any of the Borrowers, or (c) result in or require the
          imposition of any Encumbrance on any of the properties, assets or
          rights of any of the Borrowers, except (i) in favor of the
          Administrative Agent, the Issuing Bank and the Lenders, and (ii) in
          favor of the trustee for the holders of the Senior Debt and in favor
          of the holder of the Hydro Debt (or the holders of any Indebtedness
          which refinances any of the Senior Debt or the Hydro Debt) in
          accordance with the Intercreditor Agreements.

                                      -43-

     4.3  Valid Obligations. The Loan Documents and all of their respective
          terms and provisions are the legal, valid and binding obligations of
          the Borrowers, enforceable in accordance with their respective terms
          except as limited by bankruptcy, insolvency, reorganization,
          moratorium or other similar laws affecting the enforcement of
          creditors' rights generally, and except as the remedy of specific
          performance or of injunctive relief is subject to the discretion of
          the court before which any proceeding therefor may be brought. The
          Security Documents have effectively created in favor of the
          Administrative Agent, the Issuing Bank and the Lenders legal, valid
          and binding security interests in the Collateral enforceable in
          accordance with their terms, and such security interests are fully
          perfected first priority security interests, subject only to Permitted
          Encumbrances.

     4.4  Consents or Approvals. The execution, delivery and performance of the
          Loan Documents and the transactions contemplated thereby do not
          require any approval or consent of, or filing or registration with,
          any governmental or other agency or authority, or any other Person,
          except under or as contemplated by the Security Documents, all of
          which have been obtained.

     4.5  Title to Properties; Absence of Encumbrances. Each of the Borrowers
          and their Subsidiaries has good and marketable title to all of the
          properties, assets and rights of every name and nature now purported
          to be owned by it, including, without limitation, such properties,
          assets and rights as are reflected in the Initial Financial Statements
          (except such properties, assets or rights as have been disposed of in
          the ordinary course of business or as permitted by the terms hereof
          since the date thereof), free from all Encumbrances except Permitted
          Encumbrances.

     4.6  Financial Statements. The Borrowers have furnished to the Lenders the
          following financial statements (collectively, the "Initial Financial
          Statements"): (i) Holding's unaudited consolidated balance sheet as of
          September 30, 1998 and its unaudited consolidated statements of
          income, retained earnings and cash flow for the nine months then
          ended, certified by the chief financial officer of Holding; (ii) the
          unaudited combined balance sheet of NAC and NAS as of September 30,
          1998 and their combined statements of income, retained earnings and
          cash flow for the fiscal year then ended, certified by the chief
          financial officer of NAC; and (iii) the unaudited combined balance
          sheets of GNA as of September 30, 1998 and its unaudited combined

                                      -44-

          statements of income, shareholders' equity and cash flows for the nine
          months then ended, certified by the chief financial officer of GNA.
          All such financial statements were prepared in accordance with GAAP
          applied on a consistent basis throughout the periods specified and
          present fairly the financial position of the Borrowers and their
          Subsidiaries as of such dates and the results of the operations of the
          Borrowers and their Subsidiaries for such periods, subject, in the
          case of unaudited financial statements, to normal recurring year-end
          adjustments that shall not in the aggregate be material in amount. The
          Borrowers have also furnished to the Lenders their pro forma
          consolidated balance sheet as of September 30, 1998 and projections of
          their future consolidated results of operations, all of which were
          reasonable when made and continue to be reasonable at the date hereof.
          At the date hereof, the Borrowers have no Indebtedness or other
          material liabilities, debts or obligations, whether accrued, absolute,
          contingent or otherwise, and whether due or to become due, including,
          but not limited to, liabilities or obligations on account of taxes or
          other governmental charges, that are not set forth on the Initial
          Financial Statements or on Exhibit C hereto.

     4.7  Changes. Since the date of the Initial Financial Statements, there
          have been no changes in the assets, liabilities, financial condition,
          operations, business or prospects of the Borrowers or any of their
          Subsidiaries other than changes in the ordinary course of business and
          other changes, in each case the effect of which has not, in the
          aggregate, been materially adverse to the Borrowers and their
          Subsidiaries taken as a whole.

     4.8  Solvency. The Borrowers have and, after giving effect to the Loans and
          the Permitted Guarantees, will have, assets (both tangible and
          intangible) having a fair saleable value in excess of the amount
          required to pay the probable liability on its then-existing debts
          (whether matured or unmatured, liquidated or unliquidated, fixed or
          contingent); the Borrowers have and will have access to adequate
          capital for the conduct of their business and the discharge of their
          debts incurred in connection therewith as such debts mature; the
          Borrowers were not insolvent immediately prior to the making of the
          Loans and the issuance of the Permitted Guarantees, and immediately
          after giving effect thereto, the Borrowers will not be insolvent.

                                      -45-

     4.9  Defaults. As of the date of this Agreement, no Default exists.

     4.10 Taxes. The Borrowers and each Subsidiary have filed all federal, state
          and other material tax returns required to be filed, and all taxes,
          assessments and other governmental charges due from the Borrowers and
          each Subsidiary have been fully paid, except for such taxes,
          assessments or charges that are being contested in good faith by
          appropriate proceedings and with respect to which (a) adequate
          reserves have been established and are being maintained in accordance
          with GAAP and (b) no lien which is not a Permitted Encumbrance has
          been filed to secure such taxes, assessments or charges. All such
          contests at the date hereof are described on Exhibit C hereto. The
          Borrowers and their Subsidiaries have not executed any waiver that
          would have the effect of extending the applicable statute of
          limitations in respect of tax liabilities. The federal and state
          income tax returns of the Borrowers and each Subsidiary have not been
          audited or otherwise examined by any federal or state taxing
          authority. The Borrowers and each Subsidiary have established on their
          books reserves adequate for the payment of all federal, state and
          other tax liabilities.

     4.11 Litigation. There is no litigation, arbitration, proceeding or
          investigation pending, or, to the knowledge of the Borrowers' or any
          Subsidiary's officers, threatened against the Borrowers or any
          Subsidiary that, if adversely determined, may reasonably be expected
          to result in a material judgment not fully covered by insurance, may
          reasonably be expected to result in a forfeiture of all or any
          substantial part of the property of the Borrowers or their
          Subsidiaries, or may reasonably be expected to have a material adverse
          effect on the assets, business or prospects of the Borrowers and their
          Subsidiaries taken as a whole.

     4.12 Subsidiaries. Exhibit C sets forth the name, address, jurisdiction of
          incorporation and holders of equity interests of the Borrowers and
          each Subsidiary and the shares of capital stock of the Borrowers and
          each Subsidiary owned by each stockholder. All such equity interests
          have been validly issued and are fully paid and nonassessable, and no
          rights to subscribe to any additional shares have been granted, and no
          options, warrants or similar rights are outstanding.

                                      -46-

          authorizations, consents, licenses, franchises, registrations and
          other rights and privileges (including patents, trademarks, trade
          names and copyrights) to allow them to own and operate their business
          without any violation of law or the rights of others except to the
          extent that any such violation would not have a material adverse
          effect on the business, financial condition or operation of the
          Borrowers and their Subsidiaries taken as a whole; and the Borrowers
          and each Subsidiary are duly authorized, qualified and licensed under
          and in compliance with all applicable laws, regulations,
          authorizations and orders of public authorities (including, without
          limitation, Environmental Laws as provided in Section 4.16), except to
          the extent that any such failure to be so authorized, qualified,
          licensed or in compliance would not have a material adverse effect on
          the business, financial condition or operation of the Borrowers and
          their Subsidiaries taken as a whole. The Borrowers and each Subsidiary
          have performed all obligations required to be performed by them under,
          and are not in default under or in violation of, their Articles or
          Certificate of Incorporation, By-Laws or operating agreement or any
          agreement, lease, mortgage, note, bond, indenture, license or other
          instrument or undertaking to which any of them is a party or by which
          any of them or any of their properties are bound, except for
          violations none of which, either individually or in the aggregate,

          Subsidiaries taken as a whole.

     4.15 ERISA. The Borrowers and each of their Affiliates are in compliance in
          all material respects with ERISA and the provisions of the Code
          applicable to the Plans; neither the Borrowers nor any of their
          Affiliates have engaged in a Prohibited Transaction which would
          subject the Borrowers, any of their Affiliates or any Plan to a
          material tax or penalty imposed on a Prohibited Transaction; no Plan
          has incurred any "accumulated funding deficiency" (as defined in
          Section 302 of ERISA and Section 412 of the Code), whether or not
          waived; neither the Borrowers nor any of their Affiliates maintain or
          contribute to, or have maintained or contributed to in the past five
          years, any Plan that is subject to Title IV of ERISA or Section 4.12
          of the Code; and neither the Borrowers nor any of their

                                      -47-

          Affiliates have terminated any Plan in a manner which could result in
          the imposition of a lien on the property of the Borrowers or any of
          their Affiliates. None of the Borrowers or their Affiliates have

               valid requirements of any governmental authorities relative to
               their corporate existence, rights and franchises, to the conduct
               of their business and to their property and assets (including
               without limitation all Environmental Laws and ERISA), and shall
               maintain and keep in full force and effect and comply with all
               licenses and permits necessary in any material respect to the
               proper conduct of their business;

               ancillary thereto (as determined in good faith by GNA's Board of
               Directors).

     5.3  Maintenance and Insurance.
          -------------------------

          (a)  The Borrowers shall maintain their properties (including all
               Collateral) in good repair, working order and condition as
               required for the normal conduct of their business.

               insurance on their properties (including all Collateral) with
               financially sound and reputable insurers in such amounts and with
               such coverages, endorsements,

                                      -54-

               deductibles and expiration dates as the officers of the Borrowers
               in the exercise of their reasonable business judgment deem to be
               adequate, as are customary in the industry for companies of
               established reputation engaged in the same or similar business
               and owning or operating similar properties and as shall be
               reasonably satisfactory to the Administrative Agent. The
               Administrative Agent shall be named as loss payee, additional
               insured and/or mortgagee under such insurance as the
               Administrative Agent shall require from time to time, and the

               payable endorsements in form and substance reasonably

               Administrative Agent shall be given thirty (30) days advance
               notice of any cancellation of insurance. In the event of failure

               Administrative Agent may, at its option, provide such insurance
               and charge the amount thereof to the Borrowers as a Revolving
               Credit Loan. The Borrowers shall furnish to the Administrative
               Agent certificates or other evidence satisfactory to the
               Administrative Agent of compliance with the foregoing insurance
               provisions. The Administrative Agent shall not, by the fact of
               approving, disapproving or accepting any such insurance, incur
               any liability for the form or legal sufficiency of insurance
               contracts, solvency of insurance companies or payment of law
               suits, and the Borrowers hereby expressly assume full
               responsibility therefor and liability, if any, thereunder.

     5.4  Taxes. The Borrowers shall pay or cause to be paid all taxes,
          assessments or governmental charges on or against them or any of their
          Subsidiaries or their properties on or prior to the time when they

          being contested in good faith by appropriate proceedings and with
          respect to which adequate reserves have been established and are being
          maintained in accordance with GAAP if no Encumbrance (other than a
          Permitted Encumbrance) shall have been filed to secure such tax,
          assessment or charge.

     5.5  Inspection. The Borrowers shall permit the Administrative Agent, any
          Lender and their designees, at any reasonable time and at reasonable
          intervals of time, and upon reasonable notice (or if a Default shall
          have occurred and is continuing, at any time and

          the affairs, finances and accounts of GNA and the Borrowers with their

          Borrowers will permit periodic reviews (as determined by the
          Administrative Agent) of the books and records of the Borrowers and
          their Subsidiaries to be carried out by the Administrative Agent's
          commercial finance examiners. The Borrowers shall also permit the
          Administrative Agent to arrange for verification of Accounts
          Receivable, under reasonable procedures established by the
          Administrative Agent after consultation with NAC, directly with any
          account debtors or by other methods.

     5.6  Maintenance of Books and Records. The Borrowers and each of their
          Subsidiaries shall keep adequate books and records of account in which
          true and complete entries will be made reflecting all of their
          business and financial transactions in accordance with GAAP and
          applicable law. The Borrowers shall at all times keep correct and
          accurate records itemizing and describing the kind, type, quality and
          quantity of Inventory and of Eligible Inventory, the Borrowers' cost
          therefor in accordance with the Borrowers' current procedures as
          heretofore described by the Borrowers to the Lenders, and withdrawals
          therefrom and additions thereto, all of which records shall be updated
          at least monthly (or more frequently if reasonably requested by the
          Administrative Agent or, after Default, by any Lender) and shall be
          available during the Borrowers' usual business hours at the request of
          any of the Administrative Agent's officers, employees or agents.

     5.7  Use of Proceeds.

          (a)  The Borrowers will use the proceeds of Loans solely to refinance
               existing Indebtedness of the Borrowers, for the working capital
               needs of the Borrowers, including payment of the costs and
               expenses of the transactions contemplated hereby, for permitted
               Capital Expenditures and for ongoing general corporate purposes.

          (b)  No portion of any Loan shall be used for the "purpose of
               purchasing or carrying" any "margin stock" or "margin security"
               as such terms are used in Regulations G, U and X of the Board of

                                      -56-

               Governors of the Federal Reserve System, or otherwise in

          employment contracts with senior management of the Borrowers entered

               against the Borrowers by any court, or a warrant of attachment or
               execution or similar process shall be issued or levied against
               property of the Borrowers that in the aggregate exceeds

               proceedings, the Borrowers or the Affiliate, as the case may be,
               have established and are maintaining adequate reserves in
               accordance with GAAP and no lien shall have been filed to secure
               such liability; or the PBGC shall institute proceedings under
               Title IV of ERISA to terminate or to cause a trustee to be

               outstanding Voting Stock of NAC, NAS, NAT, Holding (except for
               the Holding Preferred Stock) and, following a merger between
               Holding and GAC, the survivor of such merger, and to have the
               unfettered ability at all times to approve any matter to be voted
               upon by the stockholders of the Borrowers and Holding, subject
               only to a voting agreement pertaining only to the election of

          subsections 8.1(g) and (h), immediately and automatically, and upon

          while such Event of Default is continuing, at the option of the
          Administrative Agent or the Majority Lenders and upon the
          Administrative Agent's declaration:

          (a)  the obligation of the Lenders to make any further Loans and of
               the Issuing Bank to issue any Letters of Credit hereunder and all
               Commitments shall terminate;

          (b)  the unpaid principal amount of the Loans together with accrued
               interest, all Reimbursement Obligations and all other Obligations

               respective rights by any action at law or in equity or by any
               other appropriate proceeding.

by statute or by any other provision of law. Without limiting the generality of
the foregoing or of any of the terms and provisions of any of the Security
Documents, if and when the Administrative Agent exercises remedies under the
Security Documents with respect to Collateral, the Administrative Agent may, in
its sole discretion, determine which items and types of Collateral to dispose of
and in what order and may dispose of Collateral in any order the Administrative
Agent shall select in its sole discretion, and the Borrowers consent to the

                          ASSIGNMENT AND PARTICIPATION
                          ----------------------------

     9.1  Assignment.
          ----------

          (a)  Each Lender shall have the right to assign at any time any
               portion of its Commitment hereunder and its interests in the risk
               relating to any Loans and Letter of Credit Participations in an
               amount equal to or greater than $5,000,000 to other Lenders or to
               banks or financial institutions reasonably acceptable to the
               Administrative Agent (each an "Assignee"), provided that any
               Lender which proposes to assign less than its total Commitment
               must retain a Commitment of at least $5,000,000, and provided,
               further, that if no Default or Event of Default shall have
               occurred and be continuing, each Assignee which is not a Lender
               or an Affiliate of a Lender (in each case with a domestic lending
               office for the purpose of making Loans) or a Federal Reserve Bank
               shall be subject to prior approval by the Borrowers (such
               approval not to be unreasonably withheld or delayed). Each
               Assignee shall execute and deliver to the Administrative Agent
               and the Borrowers a counterpart joinder substantially in the form
               of Exhibit F hereto and shall pay to the Administrative Agent,
               solely for the account of the Administrative Agent, an assignment
               fee of $3,500. Upon the execution and delivery of such

                                      -72-

               counterpart joinder, (a) such Assignee shall, on the date and to
               the extent provided in such counterpart joinder, become a
               "Lender" party to this Agreement and the other Loan Documents for
               all purposes of this Agreement and the other Loan Documents and
               shall have all rights and obligations of a "Lender" with a
               Commitment as set forth in such counterpart joinder, and the
               transferor Lender shall, on the date and to the extent provided
               in such counterpart joinder, be released from its obligations
               hereunder and under the other Loan Documents to a corresponding
               extent (and, in the case of an assignment covering all of the
               remaining portion of an assigning Lender's rights and obligations
               under this Agreement, such transferor shall cease to be a party
               hereto but shall continue to be entitled to the benefits of
               Section 11.3 and to any Fees accrued for its account hereunder
               and not yet paid); (b) the assigning Lender, if it holds any
               Notes, shall promptly surrender such Notes to the Administrative
               Agent for cancellation and delivery to the Borrowers, provided
               that if the assigning Lender has retained any Commitment, the
               Borrowers shall, on the request of the Administrative Agent,
               execute and deliver to the Administrative Agent for delivery to
               such assigning Lender new Notes in the amount of the assigning
               Lender's retained Commitment; (c) the Borrowers shall issue to
               such Assignee Notes in the amount of such Assignee's Commitments
               dated the Closing Date or such other date as may be specified by
               such Assignee and otherwise completed in substantially the form
               of Exhibit A hereto; (d) this Agreement shall be deemed
               appropriately amended to reflect (i) the status of such Assignee
               as a party hereto and (ii) the status and rights of the Lenders
               hereunder; and (e) the Borrowers shall take such action as the
               Administrative Agent may reasonably request to perfect any
               security interests or mortgages in favor of the Lenders,
               including any Assignee which becomes a party to this Agreement.

          (b)  If the Assignee, or any Participant pursuant to Section 9.2
               hereof, is organized under the laws of a jurisdiction other than
               the United States or any state thereof, such Assignee shall
               execute and deliver to the Borrowers, simultaneously with or
               prior to such Assignee's execution and delivery of the
               counterpart joinder described above in Section 9.1(a), and such
               Participant shall execute and deliver to the Lender granting the
               participation,

                                      -73-

               a United States Internal Revenue Service Form 4224 or Form 1001
               (or any successor form), appropriately completed, wherein such
               Assignee or Participant claims entitlement to complete exemption
               from United States Federal Withholding Tax on all interest
               payments hereunder and all Fees and other charges payable
               pursuant to any of the Loan Documents. The Borrowers shall not be
               required to pay any increased amount to any Assignee or other
               Lender on account of taxes to the extent such taxes would not
               have been payable if the Assignee or Participant had furnished
               one of the Forms referenced in this Section 9.1(b) unless the
               failure to furnish such a Form results from (i) a condition or
               event affecting the Borrowers or an act or failure to act of the
               Borrowers or (ii) the adoption of or change in any law, rule,
               regulation or guideline affecting such Assignee or Participant
               occurring (x) after the date on which any such Assignee executes
               and delivers the counterpart joinder, or (y) after the date such
               Assignee shall otherwise comply with the provisions of Section
               9.1(a), or (z) after the date a Participant is granted a
               participation.

     9.2  Participations. Each Lender shall have the right to grant
          participations to one or more banks or other financial institutions in
          all or any part of any Loans and Letter of Credit Participations owing
          to such Lender and the Notes held by such Lender. Each Lender shall
          retain the sole right to approve, without the consent of any
          participant, any amendment, modification or waiver of any provision of
          the Loan Documents, provided that the documents evidencing any such
          participation may provide that, except with the consent of such
          participant, such Lender will not consent to (a) the reduction in or
          forgiveness of the stated principal of or rate of interest on or
          Commitment Fee with respect to the portion of any Loan subject to such
          participation, (b) the extension or postponement of any stated date
          fixed for payment of principal or interest or Commitment Fee with
          respect to the portion of any Loan subject to such participation, (c)
          the waiver or reduction of any right to indemnification of such Lender
          hereunder, or (d) except as otherwise permitted hereunder, the release
          of any Collateral. Notwithstanding the foregoing, no participation
          shall operate to increase the Total Commitment hereunder or otherwise
          alter the substantive terms of this Agreement. In the event of any
          such sale by a Lender of participating interests to a participant,
          such Lender's obligations under this Agreement shall remain

                                      -74-

          unchanged, such Lender shall remain solely responsible for the
          performance thereof, such Lender shall remain the holder of such Notes
          for all purposes under this Agreement and the Borrowers and
          Administrative Agent shall continue to deal solely and directly with
          such Lender in connection with such Lender's rights and obligations
          under this Agreement.


                                       X.

                                   THE AGENTS
                                   ----------

     10.1 Appointment of Agents; Powers and Immunities.

          (a)  Each Lender and the Issuing Bank hereby irrevocably appoints and
               authorizes the Administrative Agent to act as its agent hereunder
               and under the other Loan Documents and to execute the Loan
               Documents (other than this Agreement) and all other instruments
               relating thereto. Each Lender and the Issuing Bank irrevocably
               authorizes the Administrative Agent to take such action on behalf
               of each of the Lenders and the Issuing Bank and to exercise all
               such powers as are expressly delegated to the Administrative
               Agent hereunder and in the other Loan Documents and all related
               documents, together with such other powers as are reasonably
               incidental thereto. The obligations of the Administrative Agent
               hereunder are only those expressly set forth herein. The
               Administrative Agent shall not have any duties or
               responsibilities or any fiduciary relationship with any Lender or
               the Issuing Bank except those expressly set forth in this
               Agreement.

          (b)  Each Lender and the Issuing Bank hereby irrevocably appoints the
               Documentation Agent as documentation agent hereunder and under
               the other Loan Documents and authorizes the Documentation Agent
               to take such action on behalf of each of the Lenders and the
               Issuing Bank and to exercise all such powers on their behalf as
               are expressly delegated to the Documentation Agent by the
               Administrative Agent, together with such other powers as are
               reasonably incidental thereto. The Documentation Agent shall not
               have any duties or responsibilities or any fiduciary relationship
               with any Lender or the Issuing Bank except those expressly set
               forth in this Agreement.

                                      -75-

          (c)  Neither the Agents nor any of their directors, officers,
               employees or agents shall be responsible for any action taken or
               omitted to be taken by any of them hereunder or in connection
               herewith, except for their own gross negligence or willful
               misconduct. Without limiting the generality of the foregoing,
               neither the Agents nor any of their Affiliates shall be
               responsible to the Lenders or the Issuing Bank for or have any
               duty to ascertain, inquire into or verify: (i) any recitals,
               statements, representations or warranties made by the Borrowers
               or any of their Subsidiaries or any other Person whether
               contained herein or otherwise; (ii) the value, validity,
               effectiveness, genuineness, enforceability or sufficiency of this
               Agreement, the other Loan Documents or any other document
               referred to or provided for herein or therein; (iii) any failure
               by the Borrowers or any other Person to perform its obligations
               under any of the Loan Documents; (iv) the satisfaction of any
               conditions specified in Section 3 hereof, other than receipt of
               the documents, certificates and opinions specified in Section
               3.1(a) hereof; (v) the existence, value, collectibility or
               adequacy of the Collateral or any part thereof or the validity,
               effectiveness, perfection or relative priority of the liens and
               security interests of the Lenders and the Issuing Bank therein;
               or (vi) the filing, recording, refiling, continuing or re-
               recording of any financing statement or other document or
               instrument evidencing or relating to the security interests or
               liens of the Lenders and the Issuing Bank in the Collateral.

          (d)  The Agents may employ agents, attorneys and other experts, shall
               not be responsible to any Lender or the Issuing Bank for the
               negligence or misconduct of any such agents, attorneys or experts
               selected by it with reasonable care and shall not be liable to
               any Lender or the Issuing Bank for any action taken, omitted to
               be taken or suffered in good faith by it in accordance with the
               advice of such agents, attorneys and other experts. Each of BKB
               and US Bank, in its separate capacity as a Lender, shall have the
               same rights and powers under the Loan Documents as any other
               Lender and may exercise or refrain from exercising the same as
               though it were not an Agent, and each of BKB and US Bank and its
               Affiliates may accept deposits from, lend money to and generally
               engage in any

                                      -76-

               kind of business with the Borrowers as if it were not an Agent.

     10.2 Actions by Agents.
          -----------------

          (a)  Each of the Agents shall be fully justified in failing or
               refusing to take any action under this Agreement as it reasonably
               deems appropriate unless it shall first have received such advice
               or concurrence of the Lenders and shall be indemnified to its
               reasonable satisfaction by the Lenders against any and all
               liability and expense which may be incurred by it by reason of
               taking or continuing to take any such action. The Agents shall in
               all cases be fully protected in acting, or in refraining from
               acting, under this Agreement or any of the Loan Documents in
               accordance with a request of the Lenders or the Majority Lenders,
               as the case may be, 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 Notes. Without limiting the
               generality of the foregoing, as among the Agents and the Lenders
               (but not for the benefit of the Borrowers), if and when the
               Administrative Agent exercises remedies under the Security
               Documents with respect to Collateral, the Administrative Agent
               will follow the directions, if any, of the Majority Lenders in
               determining which items and types of Collateral to dispose of and
               in what order.

          (b)  Whether or not an Event of Default shall have occurred, the
               Administrative Agent may from time to time exercise such rights
               of the Administrative Agent and the Lenders under the Loan
               Documents as it determines may be necessary or desirable to
               protect the Collateral and the interests of the Administrative
               Agent, the Issuing Bank and the Lenders therein and under the
               Loan Documents. In addition, the Administrative Agent may,
               without the consent of the Lenders, release Collateral valued by
               the Administrative Agent, in its reasonable discretion, of not
               more than $1,000,000 in any year.

          (c)  Neither Agent nor any of its directors, officers, employees or
               agents shall incur any liability by acting in reliance on any
               notice, consent, certificate, statement or other writing (which
               may be a bank wire, telex, facsimile or similar writing) believed
               by any of them to be genuine or to be signed by the proper party
               or parties.

                                      -77-

     10.3 Indemnification. Without limiting the obligations of the Borrowers
          hereunder or under any other Loan Document, the Lenders agree to
          indemnify the Agents and the Issuing Bank, ratably in accordance with
          their respective Commitment Percentages, for any and all liabilities,
          obligations, losses, damages, penalties, actions, judgments, suits,
          costs, expenses or disbursements of any kind or nature whatsoever
          which may at any time be imposed on, incurred by or asserted against
          the Agents or the Issuing Bank in any way relating to or arising out
          of this Agreement or any other Loan Document or any documents
          contemplated by or referred to herein or therein or the transactions
          contemplated hereby or thereby or the enforcement of any of the terms
          hereof or thereof or of any such other documents; provided, that no
          Lender shall be liable for any of the foregoing to the extent they
          result from the gross negligence or willful misconduct of an Agent or
          the Issuing Bank, as the case may be.

     10.4 Reimbursement. Without limiting the provisions of Section 10.3, the
          Lenders, the Issuing Bank and the Agents hereby agree that the
          Administrative Agent shall not be obliged to make available to any
          Person any sum which the Administrative Agent is expecting to receive
          for the account of that Person until the Administrative Agent has
          determined that it has received that sum. The Administrative Agent
          may, however, disburse funds prior to determining that the sums which
          the Administrative Agent expects to receive have been finally and
          unconditionally paid to the Administrative Agent if the Administrative
          Agent wishes to do so. If and to the extent that the Administrative
          Agent does disburse funds and it later becomes apparent that the
          Administrative Agent did not then receive a payment in an amount equal
          to the sum paid out, then any Person to whom the Administrative Agent
          made the funds available shall, on demand from the Administrative
          Agent refund to the Administrative Agent the sum paid to that Person.
          If the Administrative Agent in good faith reasonably concludes that
          the distribution of any amount received by it in such capacity
          hereunder or under 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

                                      -78-

          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.

     10.5 Non-Reliance on Agents and Other Lenders. Each Lender represents that
          it has, independently and without reliance on the Agents or any other
          Lender, and based on such documents and information as it has deemed
          appropriate, made its own appraisal of the financial condition and
          affairs of the Borrowers and decision to enter into this Agreement and
          the other Loan Documents and agrees that it will, independently and
          without reliance upon the Agents or any other Lender, and based on
          such documents and information as it shall deem appropriate at the
          time, continue to make its own appraisals and decision in taking or
          not taking action under this Agreement or any other Loan Document. The
          Agents shall not be required to keep informed as to the performance or
          observance by the Borrowers of this Agreement, the other Loan
          Documents or any other document referred to or provided for herein or
          therein or by any other Person of any other agreement or to make
          inquiry of, or to inspect the properties or books of, any Person.
          Except for notices, reports and other documents and information
          expressly required to be furnished to the Lenders by the Agents
          hereunder, the Agents shall not have any duty or responsibility to
          provide any Lender with any credit or other information concerning any
          Person which may come into the possession of any Agent or any of its
          affiliates. Each Lender shall have access to all documents relating to
          each Agent's performance of its duties hereunder at such Lender's
          request. Unless any Lender shall, promptly after obtaining knowledge
          thereof, object to any action taken by any Agent hereunder (other than
          actions to which the provisions of Section 11.7(b) are applicable and
          other than actions which constitute gross negligence or willful
          misconduct by any Agent), such Lender shall conclusively be presumed
          to have approved the same.

     10.6 Resignation or Removal of an Agent. An Agent may resign at any time by
          giving 30 days prior written notice thereof to the other Agent, the
          Lenders and the Borrowers. Upon any such resignation, the Lenders
          shall have the right to appoint a successor Agent which shall be
          reasonably acceptable to the Borrowers and shall be a financial
          institution having a combined capital and surplus in excess of
          $150,000,000. If no successor Agent shall have been so appointed by
          the Lenders and shall have accepted such appointment within 30 days
          after the retiring Agent's giving of notice of

                                      -79-

          resignation, then the retiring Agent may, on behalf of the Lenders,
          appoint a successor Agent which shall be reasonably acceptable to the
          Borrowers and shall be a financial institution having a combined
          capital and surplus in excess of $150,000,000. Upon the acceptance of
          any appointment as Agent hereunder by a successor Agent, such
          successor Agent shall thereupon succeed to and become vested with all
          the rights, powers, privileges and duties of the retiring Agent, and
          the retiring Agent shall be discharged from its duties and obligations
          hereunder. After any retiring Agent's resignation, the provisions of
          this Agreement shall continue in effect for its benefit in respect of
          any actions taken or omitted to be taken by it while it was acting as
          Agent.

     10.7 Intercreditor Agreements. Each Lender and the Issuing Bank hereby
          irrevocably appoints and authorizes the Administrative Agent on their
          behalf (i) to execute the Intercreditor Agreements and all other
          instruments relating thereto, and (ii) to act under and in accordance
          with the terms of the Intercreditor Agreements.

     11.2 Expenses. Whether or not the transactions contemplated hereby shall be
          consummated, the Borrowers jointly and severally promise to reimburse
          (a) the Agents, the Issuing Bank and the Initial Lenders for all
          reasonable out-of-pocket costs, fees and disbursements (including all
          Attorneys' Fees, appraisal and collateral examination fees, due
          diligence investigation expenses and syndication expenses) incurred or
          expended in connection with the preparation, negotiation, execution,
          delivery, filing or recording, or the administration or interpretation
          of this Agreement and the other Loan Documents, or the consummation of
          the transactions contemplated hereby, or any amendment, modification,
          approval, consent or waiver hereof or thereof, and (b) the Agents, the
          Issuing Bank and all of the Lenders for all reasonable out-of-pocket
          costs, fees and disbursements (including all Attorneys' Fees,
          appraisal and collateral examination fees, and collection expenses)
          incurred or expended in connection with the enforcement of any
          Obligations, the exercise of any remedies under any Loan Documents or
          with

                                      -81-

          respect to the Collateral or the satisfaction of any Indebtedness of
          the Borrowers hereunder or thereunder, or in connection with any
          litigation, proceeding or dispute in any way related to the credit
          hereunder. The Administrative Agent may include references to GNA and
          the Borrowers (and may utilize any logo or other distinctive symbol
          associated with GNA or the Borrowers) in connection with any
          advertising, promotion or marketing undertaken by the Administrative
          Agent. The Borrowers will pay any taxes (including any interest and
          penalties in respect thereof), other than the Lenders' federal and
          state income taxes, payable on or with respect to the transactions
          contemplated by the Loan Documents (the Borrowers hereby agreeing to
          indemnify the Agents, the Issuing Bank and the Lenders with respect
          thereto). For purposes of this Agreement and the other Loan Documents,
          "Attorneys' Fees" shall mean the reasonable fees and disbursements of
          attorneys (including all paralegals and other staff employed by such
          attorneys and the reasonably allocated costs of internal counsel),
          whether incurred at arbitration, trial, on appeal, in a bankruptcy
          proceeding or in any other way relating to Obligations, the Loan
          Documents and the transactions contemplated thereby, including,
          without limitation, as provided in Sections 11.2 and 11.3 hereof;
          provided, however, that Attorneys' Fees shall not include any
          attorneys' fees incurred by the Agents, the Issuing Bank or any Lender
          in any court proceeding (other than a proceeding under or related to
          11 U.S.C. ss.101 et. seq.) if (i) such fees were incurred in an action
          by such Agent, Issuing Bank, or Lender, on the one hand, or the
          Borrowers, on the other hand, against the other such party, and (ii)
          Borrowers are the prevailing party in such action.

     11.3 Indemnification. The Borrowers agree to indemnify and hold harmless
          the Agents, the Issuing Bank and the Lenders, as well as their
          respective shareholders, directors, offices, agents, attorneys,
          subsidiaries and affiliates, from and against all damages, losses,
          settlement payments, obligations, liabilities, claims, suits,
          penalties, assessments, citations, directives, demands, judgments,
          actions or causes of action, whether statutorily created or under the
          common law, all reasonable costs and expenses (including, without
          limitation, Attorneys' Fees and reasonable fees and disbursements of
          engineers and consultants) and all other liabilities whatsoever
          (including, without limitation, liabilities under Environmental Laws)
          which shall at any time or times be incurred, suffered, sustained or
          required to be paid by any such indemnified Person (except any of the
          foregoing which

                                      -82-

          result from the gross negligence or willful misconduct of the
          indemnified Person) by reason of a claim made against such indemnified
          Person on account of or in relation to or any way in connection with
          any of the arrangements or transactions contemplated by, associated
          with or ancillary to this Agreement, the other Loan Documents or any
          other documents executed or delivered in connection herewith or
          therewith, all as the same may be amended from time to time, or with
          respect to any Letters of Credit, whether or not all or part of the
          transactions contemplated by, associated with or ancillary to this
          Agreement, any of the other Loan Documents or any such other documents
          are ultimately consummated. In any investigation, proceeding or
          litigation, or the preparation therefor, the Lenders shall select
          their own counsel and, in addition to the foregoing indemnity, the
          Borrowers agree to pay promptly the reasonable fees and expenses of
          such counsel. In the event of the commencement of any such proceeding
          or litigation, the Borrowers shall be entitled to participate in such
          proceeding or litigation with counsel of its choice at its own
          expense, provided that such counsel shall be reasonably satisfactory
          to the Administrative Agent. The Borrowers authorize the Agents, the
          Issuing Bank and the Lenders to charge any deposit account or Note
          Record which it may maintain with any of them for any of the
          foregoing. The covenants of this Section 11.3 shall survive payment or
          satisfaction of payment of all amounts owing with respect to the
          Notes, any other Loan Document or any other Obligation.

     11.4 Survival of Covenants, Etc. Unless otherwise stated herein, 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 Borrowers pursuant hereto shall be deemed to
          have been relied upon by the Agents, the Issuing Bank and the Lenders,
          notwithstanding any investigation heretofore or hereafter made by any
          of them, and shall survive the making by the Lenders of the Loans as
          herein contemplated, and shall continue in full force and effect so
          long as any Obligation remains outstanding and unpaid or any Lender
          has any obligation to make any Loans hereunder or the Issuing Bank has
          any obligation to issue any Letter of Credit. All statements contained
          in any certificate or other writing delivered by or on behalf of the
          Borrowers pursuant hereto or in connection with the transactions
          contemplated hereby shall constitute representations and warranties by
          the Borrowers hereunder.

                                      -83-

     11.5 Set-Off. Regardless of the adequacy of any Collateral or other means
          of obtaining repayment of the Obligations, but subject to the
          provisions of Section 2.8(d) hereof, any deposits, balances or other
          sums credited by or due from the head office of any Lender or any of
          its branch offices to the Borrowers may, at any time and from time to
          time after the occurrence of a Default hereunder, upon notice to the
          Administrative Agent but without notice to the Borrowers or compliance
          with any other condition precedent now or hereafter imposed by
          statute, rule of law, or otherwise (all of which are hereby expressly
          waived) be set off, appropriated, and applied by such Lender against
          any and all Obligations of the Borrowers in such manner as the head
          office of such Lender or any of its branch offices in its sole
          discretion may determine, and the Borrowers hereby grant each such
          Lender a continuing security interest in such deposits, balances or
          other sums for the payment and performance of all such Obligations.

     11.6 No Waivers. No failure or delay by the Administrative Agent, the
          Issuing Bank or any Lender in exercising any right, power or privilege
          hereunder, under the Notes or under any other Loan Document shall
          operate as a waiver thereof; nor shall any single or partial exercise
          thereof preclude any other or further exercise thereof or the exercise
          of any other right, power or privilege. No waiver shall extend to or
          affect any Obligation not expressly waived or impair any right
          consequent thereon. No course of dealing or omission on the part of
          the Administrative Agent, the Issuing Bank or the Lenders 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. The rights and remedies herein and in the
          Notes and the other Loan Documents are cumulative and not exclusive of
          any rights or remedies otherwise provided by agreement or law.

     11.7 Amendments, Waivers, etc.
          -------------------------

          (a)  Neither this Agreement nor the Notes nor any other Loan Document
               nor any provision hereof or thereof may be amended, waived,
               discharged or terminated except by a written instrument signed by
               the Administrative Agent on behalf of the Lenders or by the
               Lenders and, with respect to Letters of Credit, the Issuing Bank,
               and, in the case of amendments, by the Borrowers.

                                      -84-

          (b)  Except where this Agreement or any of the other Loan Documents
               authorizes or permits the Administrative Agent to act alone and
               except as otherwise expressly provided in this Section 11.7(b),
               any action to be taken (including the giving of notice) by the
               Lenders may be taken, and any consent or approval required or
               permitted by this Agreement or any other Loan Document to be
               given by the Lenders may be given, and any term of this
