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

         2.7.3.  Eurodollar Rate Loans.
                 ---------------------

         Any conversion to or from Eurodollar Rate Loans shall be in such
    amounts and be made pursuant to such elections so that, after giving effect
    thereto, the aggregate principal amount of all Eurodollar Rate Loans having
    the same Interest Period shall not be less than $1,000,000 or an integral
    multiple of $100,000 in excess thereof.  In addition, no more than seven (7)
    Eurodollar Rate Loans (in the aggregate including Revolving Credit Loans and
    Term Loans) having different Interest Periods shall be outstanding at any
    one time.

     2.8.  Funds for Revolving Credit Loans.
           --------------------------------

          2.8.1.  Funding Procedures.
                  ------------------

          Not later than 2:00 p.m. (Boston time) on the proposed Drawdown Date
     of any Revolving Credit Loans, each of the Banks will make available to the
     Agent, at the Agent's Head Office, in immediately available funds, the
     amount of such Bank's Commitment Percentage of the amount of the requested
     Revolving Credit Loans.  Upon receipt from each Bank of such amount, and
     upon receipt of the documents required by (S)(S)12 and 13 and the
     satisfaction of the other conditions set forth therein, to the extent
     applicable, the Agent will make available to the Borrower the aggregate
     amount of such Revolving Credit Loans made available to the
<PAGE>

                                      -31-

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

          2.8.2.  Advances by Agent.
                  -----------------

          The Agent may, unless notified to the contrary by any Bank prior to a
     Drawdown Date, assume that such Bank has made available to the Agent on
     such Drawdown Date the amount of such Bank's Commitment Percentage of the
     Revolving Credit Loans to be made on such Drawdown Date, and the Agent may
     (but it shall not be required to), in reliance upon such assumption, make
     available to the Borrower a corresponding amount.  If any Bank makes
     available to the Agent such amount on a date after such Drawdown Date, such
     Bank shall pay to the Agent on demand an amount equal to the product of (a)
     the average computed for the period referred to in clause (c) below, of the
     weighted average interest rate per annum paid by the Agent for federal
     funds acquired by the Agent during each day included in such period, times
                                                                          -----
     (b) the amount of such Bank's Commitment Percentage of such Revolving
     Credit Loans, times (c) a fraction, the numerator of which is the number of
                   -----
     days that elapse from and including such Drawdown Date to the date on which
     the amount of such Bank's Commitment Percentage of such Revolving Credit
     Loans shall become immediately available to the Agent, and the denominator
     of which is 365.  A statement of the Agent submitted to such Bank with
     respect to any amounts owing under this paragraph shall be prima facie
                                                                ----- -----
     evidence of the amount due and owing to the Agent by such Bank.  If the
     amount of such Bank's Commitment Percentage of such Revolving Credit Loans
     is not made available to the Agent by such Bank within four (4) Business
     Days following such Drawdown Date, the Agent shall be entitled to recover
     such amount from the Borrower on demand, with interest thereon at the rate
     per annum applicable to the Revolving Credit Loans made on such Drawdown
     Date.

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

     3.1.  Maturity.
           --------

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

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

     If at any time the sum of the outstanding amount of the Revolving Credit
Loans, the Maximum Drawing Amount and all Unpaid Reimbursement Obligations
exceeds the Total Commitment, then the Borrower shall immediately pay the amount
of such excess to the Agent for the respective accounts of the Banks for
application:  first, to any Unpaid Reimbursement Obligations; second, to the
Revolving Credit Loans; and third, to provide to the Agent cash collateral for
Reimbursement Obligations as contemplated by (S)5.2(b) and (c).  Each payment of
any Unpaid Reimbursement Obligations or prepayment of Revolving Credit Loans
shall be allocated among the Banks, in proportion, as nearly as practicable, to
each Reimbursement Obligation or (as the case may be) the respective unpaid
principal amount of the Revolving Credit Loans owing to such Bank, with
adjustments to the extent practicable to equalize any prior payments or
repayments not exactly in proportion.
<PAGE>

                                      -32-

     3.3.  Optional Repayments of Revolving Credit Loans.
           ---------------------------------------------

     The Borrower shall have the right, at its election, to repay the
outstanding amount of the Revolving Credit Loans, as a whole or in part, at any
time without penalty or premium (but subject to (S)6.10).  The Borrower shall
give the Agent, no later than 11:00 a.m., Boston time, on the date of any
proposed prepayment written notice of any proposed prepayment pursuant to this
(S)3.3 of Base Rate Loans, and three (3) Eurodollar Business Days' prior written
notice of any proposed prepayment pursuant to this (S)3.3 of Eurodollar Rate
Loans, in each case specifying the proposed date of prepayment of Revolving
Credit Loans and the principal amount to be prepaid.  Each such partial
prepayment of the Revolving Credit Loans shall be in a minimum aggregate amount
of $250,000 or a whole multiple of $50,000 in excess thereof and shall be
applied, in the absence of instruction by the Borrower, first to the principal
of Base Rate Loans and then to the principal of Eurodollar Rate Loans or both,
at the Agent's option.  Each partial prepayment shall be allocated among the
Banks, in proportion, as nearly as practicable, to the respective unpaid
principal amount of each Bank's Revolving Credit Note, with adjustments to the
extent practicable to equalize any prior repayments not exactly in proportion.

     4.  THE TERM LOANS.

     specified herein, and (b) the Total Commitment minus $25,000,000, shall be
                                                    -----
     converted into a Term Loan A, held severally by the Banks in accordance
     with their Commitment Percentages.  On the Conversion Date the Borrower
     shall pay to the Agent for the pro rata accounts of the Banks all interest
                                    --- -----
     accrued to such date on the Revolving Credit Loans so converted, together
     with any Unpaid Reimbursement Obligations, any commitment fees and other
     fees payable to the Agent and the Banks hereunder, and, as soon as
     reasonably practicable after such payment, each Bank shall surrender to the
     Borrower its Revolving Credit Note (if any) and the Borrower shall, if
     requested by such Bank, execute and deliver (i) a Term A Note evidencing
     the amount of the outstanding Revolving Credit Loans so converted, and (ii)
     a new Revolving Credit Note evidencing such Bank's Commitment Percentage of
     the Total Commitment in effect following the Conversion Date.

          4.1.2.  Loan Account.
                  ------------

          (a) The Term Loan A and the Obligations of the Borrower in respect
     thereof shall be evidenced by this Credit Agreement and the Loan Account
     maintained by each Bank with respect to the Term Loan A.  The Borrower
     irrevocably authorizes each Bank to make or cause to be made, at or about
     the time of the Drawdown Date of the Term Loan A or at the time of receipt
     of any payment of principal on such Term Loan A, an appropriate notation in
     such Loan Account reflecting the making of such Term Loan A or (as the case
     may be) the receipt of such payment.  The outstanding amount of the Term
     Loan A set forth in such Loan Account shall be prima facie evidence (absent
                                                    ----- -----
     manifest error) of the principal amount thereof owing and unpaid to such
     Bank, but the failure to record, or any error in so recording, any such
     amount in such Loan Account
<PAGE>

     pay the Term Loan A in accordance with the terms hereof.

          (b) The Borrower agrees that, upon the request to the Agent by any
     Bank, the Borrower will execute and deliver to such Bank a promissory note
     of the Borrower evidencing the Term Loan A of such Bank, substantially in

     principal amount of the Term Loan A outstanding on the Conversion Date,
     such installments to be due and payable on the last day of each calendar

     Loan A shall bear interest during each Interest Period relating to all or
     any portion of Term Loan A at the following rates:

               (i)  To the extent that all or any portion of Term Loan A bears
          interest during such Interest Period based on the Base Rate, Term Loan

          the rate per annum of the Base Rate plus the Applicable Margin.
                                              ----

               (ii) To the extent that all or any portion of Term Loan A bears
          interest during such Interest Period based on the Eurodollar Rate,

               The Borrower irrevocably and unconditionally promises to pay
          interest on Term Loan A or any portion thereof outstanding during each
          Interest Period in arrears on each Interest Payment Date applicable to

     such notice to be irrevocable, at least three (3) Business Days prior to

     of any payment of principal on such Term Loan B, an appropriate notation in
     such Loan Account reflecting the making of such Term Loan B or (as the case

     A, with adjustments to the extent practicable to equalize any prior
     prepayments not exactly in proportion. Any prepayment of principal of the
     Term Loan A shall include all interest accrued to the date of prepayment
     and shall be applied pro rata against the remaining scheduled installments
     of principal due on the Term Loan A. No amount repaid with respect to the

     each partial prepayment shall be allocated among the Banks, in proportion,
     as nearly as practicable, to the respective outstanding amount of each
     Bank's Term Loan B, with adjustments, to the extent practicable, to
     equalize any prior prepayments not exactly in proportion.  Any prepayment
     of principal of the Term Loan B shall be applied against the scheduled
     installments of principal due on the Term Loan B in the inverse order of
     maturity.  No amount repaid with respect to the Term Loan B may be
     reborrowed.  If the Borrower prepays the Term Loan B in whole or in part,
     the Borrower shall pay a premium with respect to each such prepayment in an
     amount determined in accordance with the percentages set forth in the
     following table opposite the period during which such prepayment is made:

          Concurrently with the receipt by the Borrower or any of its
     Subsidiaries of cash proceeds from (a) sales or other dispositions of
     assets (other than the sale or disposition of assets in the ordinary course
     of business consistent with past practices) which exceed, in the aggregate,
     $1,000,000 during the period commencing on the Effective Date and over the
     term of this Credit Agreement, (b) the sale of stock, partnership interests
     or other equity issuances of the Borrower or any of its Subsidiaries other
     than in connection with the Borrower's equity incentive plan, and private
     investments by existing investors and their affiliates in an aggregate
     amount not to exceed $10,000,000, (c) proceeds from debt issuances other
     than those permitted pursuant to (S)10.1, and (d) insurance claims received
     by the Borrower or its Subsidiaries which have not been either (i)
     reinvested by the Borrower or such Subsidiary within one year of receipt by
     such Person of such proceeds (and, for purposes of this (S)4.4.1(d)(i), to
     the extent the Borrower or any such Subsidiary purchased any Replacement
     Asset or commenced repairs not more than ninety (90) days prior to the
     Borrower's or such Subsidiary's receipt of the claimed amounts but after
     the casualty that gave rise to such proceeds, such a purchase or repair
     costs shall be considered as being reinvested for purposes of this

     financing), on or prior to the 270th day following the Borrower's or such
     Subsidiary's receipt of the claimed amount and the claimed amounts
     contractually committed are so applied within 365 days following receipt of
     such amounts, the Borrower shall pay to the Agent for the respective
     accounts of the Banks an amount equal to 100% of such proceeds, to be
     applied if such prepayment is made prior to the Conversion Date, to the
     Term Loan B based on the then outstanding amount of the Term Loan B and
     applied against the scheduled installments of principal due in the inverse
     order of maturity, or, if such prepayment is made following the Conversion
     Date, to be applied pro rata to each of the Term Loans based on the then
                         --------
     outstanding amounts of the Term Loans and applied against the scheduled
     installments of principal due or the respective Term Loans in the inverse
     order of maturity.  Furthermore, if following the Conversion Date, there
     are no amounts outstanding under the Term Loans, to be applied to the
     outstanding Revolving Credit Loans and to permanently reduce the Total
     Commitment by such amount.  Notwithstanding the foregoing clause (a), at
     any time when the Leverage Ratio as of the most recent fiscal quarter end
     is less than 4.50:1, the Borrower or any of its Subsidiaries shall not be
     required to pay to the Agent for the respective accounts of the Banks, any
     cash proceeds in excess of $1,000,000 received by the Borrower or such
     Subsidiaries from sales or other dispositions of assets so long as such
     proceeds are (i) either (A) reinvested by the Borrower in Replacement
     Assets in which the Agent shall have a first priority perfected security
     interest for the benefit of the Agent and the Banks (subject only to those
     liens permitted pursuant to (S)10.2(a), (S)10.2(b), (S)10.2(e), (S)10.2(f),

     Subsidiary purchased any Replacement Asset not more than thirty (30) days
     prior to the Borrower's or such Subsidiary's receipt of the cash proceeds
     of any such sale or disposition, such a purchase shall be considered as
     being reinvested for purposes of this (S)4.4.1, or (B) subject to a

     evidencing compliance, after giving effect to the purchase of such
     Replacement Asset, with the financial covenants contained in (S)11.

          4.4.2.  Excess Cash Flow Recapture.
                  --------------------------

          Commencing with the Borrower's 2001 fiscal year, and for each fiscal
     year thereafter, the Borrower promises to pay to the Agent for the pro rata
                                                                        --- ----
     accounts of the Banks: (a) on or before May 15 of each year, an amount
     equal to twelve and one-half of one percent (12.5%) of the Consolidated
     Excess Cash Flow for the fiscal quarter ending closest to March 31 of such
     year, (b) on or before August 15 of each year, an amount (when added to the
     amount paid in such year pursuant to clause (a) hereof), equal to twenty-
     five percent (25%) of the Consolidated Excess Cash Flow for the period of
     two fiscal quarters ending closest to June 30 of such year, (c) on or
     before
<PAGE>

                                      -38-

     November 15 of each year, an amount (when added to the amount paid in such
     year pursuant to clause (b) hereof), equal to thirty-seven and one-half of
     one percent (37.5%) of the Consolidated Excess Cash Flow for the period of
     three fiscal quarters ending closest to September 30 of such year and (d)
     on or before April 15 of the subsequent year, an amount (when added to the
     amount paid with respect to such year pursuant to clause (c) hereof), equal
     to one hundred percent (100%) of the Consolidated Excess Cash Flow to such
     fiscal year. Notwithstanding the foregoing, if with respect to any fiscal
     quarter ending during such year, the Borrower can demonstrate to the
     reasonable satisfaction of the Agent that the Leverage Ratio as at the end
     of such fiscal quarter was less than 4.50:1 and no Default or Event of
     Default has occurred and is continuing, then the amount required to be paid
     hereunder following the end of such fiscal quarter shall be one-half of the
     amount required in the preceding sentence with respect to such fiscal
     quarter. Additionally, in the event that the Leverage Ratio as at the end
     of any fiscal year and as at the end of the first fiscal quarter ending
     thereafter is less than 4.50:1 and no Default or Event of Default has
     occurred and is continuing, payments in respect of Consolidated Excess Cash
     Flow shall only be required on an annual basis. Additionally, with respect
     to the payment required on April 15 with respect to the preceding fiscal
     year, if the Borrower can demonstrate to the reasonable satisfaction of the
     Agent that (a) the Leverage Ratio as at the end of each of (i) the fiscal
     year for which such payment is to be made and (ii) the fiscal quarter
     occurring immediately preceding the date such payment is due and payable
     was less than 4.50:1.00 and (b) no Default or Event of Default has occurred
     and is continuing, then the reference to one hundred percent (100%) in
     clause (d) above shall instead be fifty percent (50%). Such payment shall
     be applied, if such prepayment is made prior to the Conversion Date, to the
     Term Loan B based on the then outstanding amount of the Term Loan B and
     applied against the scheduled installments of principal due in the inverse
     order of maturity, or, if such prepayment is made following the Conversion
     Date, to be applied pro rata to each of the Term Loans based on the then
                         --- ----
     outstanding amounts of the Term Loans and applied against the scheduled
     installments of principal due on the respective Term Loans and applied
     against the scheduled installments of principal due or the respective Term
     Loans in the inverse order of maturity. Following the Conversion Date, or
     if there are no amounts outstanding under the Term Loans, such amounts
     shall be applied to the outstanding Revolving Credit Loans and to
     permanently reduce the Total Commitment by such amount.

          4.4.3.  Application.
                  -----------

          In the event any holder of the Term Loan B elects not to receive any
     prepayments it is otherwise entitled to receive pursuant to this (S)4.4 and
     so notifies the Agent in writing of such election prior to the time such
     payment is due, all such prepayments such holder was otherwise entitled to
     receive pursuant to this (S)4.4 shall be applied to the Term Loan A, or, if
     there are no outstanding amounts due under the Term Loan A, or if such
     payment is made prior to the Conversion Date, then to repay outstanding
     Revolving Credit Loans to the extent of the amounts outstanding under the
     Revolving Credit Loans and to provide cash collateral for the Obligations
     and to permanently reduce the Total Commitment by such amount.  The Agent
     shall promptly notify the Borrower in writing of any such elections.

          Notwithstanding the requirements of (S)(S)4.4.1, 4.4.2, and 4.4.3, no
     repayments under this (S)4.4 shall be applied to reduce the Total
     Commitment to an amount less than
<PAGE>

                                      -39-

     $25,000,000. If any such payment would otherwise be required, it shall be
     applied to repay any outstanding Revolving Credit Loans (or cash
     collateralize Letters of Credit, if any) but not to reduce the Total
     Commitment.

     5.  LETTERS OF CREDIT.
         -----------------

     5.1.  Letter of Credit Commitments.
           ----------------------------

          5.1.1.  Commitment to Issue Letters of Credit.
                  -------------------------------------

          Subject to the terms and conditions hereof and the execution and
     delivery by the Borrower of a letter of credit application on the Agent's
     customary form (a "Letter of Credit Application"), the Agent on behalf of
     the Banks and in reliance upon the agreement of the Banks set forth in
     (S)5.1.4 and upon the representations and warranties of the Borrower
     contained herein, agrees, in its individual capacity, to issue, extend and
     renew for the account of the Borrower one or more standby letters of credit
     (individually, a "Letter of Credit"), in such form as may be requested from
     time to time by the Borrower and agreed to by the Agent; provided, however,
                                                              --------  -------
     that, after giving effect to such request, (a) the sum of the aggregate
     Maximum Drawing Amount and all Unpaid Reimbursement Obligations shall not
     exceed $10,000,000 at any one time and (b) the sum of (i) the Maximum
     Drawing Amount on all Letters of Credit, (ii) all Unpaid Reimbursement
     Obligations, and (iii) the amount of all Revolving Credit Loans outstanding
     shall not exceed the Total Commitment.

          5.1.2.  Letter of Credit Applications.
                  -----------------------------

          Each Letter of Credit Application shall be completed to the
     satisfaction of the Agent.  In the event that any provision of any Letter
     of Credit Application shall be inconsistent with any provision of this
     Credit Agreement, then the provisions of this Credit Agreement shall, to
     the extent of any such inconsistency, govern, it being understood and
     agreed that the provisions of the Letter of Credit Application regarding
     indemnification, set-off, insecurity and default shall be governed by the
     indemnification, set-off, default and remedies provisions of this Credit
     Agreement.

          5.1.3.  Terms of Letters of Credit.
                  --------------------------

          Each Letter of Credit issued, extended or renewed hereunder shall,
     among other things, (a) provide for the payment of sight drafts for honor
     thereunder when presented in accordance with the terms thereof and when
     accompanied by the documents described therein, and (b) have an expiry date
     no later than the date which is fourteen (14) days (or, if the Letter of
     Credit is confirmed by a confirmer or otherwise provides for one or more
     nominated persons, thirty (30) days) prior to the Revolving Credit Loan
     Maturity Date. Each Letter of Credit so issued, extended or renewed shall
     be subject to the Uniform Customs or, in the case of a standby Letter of
     Credit issued on or after January 1, 1999, either the Uniform Customs or
     International Standby Practices.

          5.1.4.  Reimbursement Obligations of Banks.
                  ----------------------------------

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

                                      -40-

          5.1.5.  Participations of Banks.
                  -----------------------

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

     5.2.  Reimbursement Obligation of the Borrower.
           ----------------------------------------

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

          (a)  except as otherwise expressly provided in (S)5.2(b) and (c) and
     subject to the last sentence of (S)5.3, on each date that any draft
     presented under such Letter of Credit is honored by the Agent, or the Agent
     otherwise makes a payment with respect thereto, (i) the amount paid by the
     Agent under or with respect to such Letter of Credit, and (ii) the amount
     of any taxes, fees, charges or other costs and expenses reasonably incurred
     by the Agent or any Bank in connection with any payment made by the Agent
     or any Bank under, or with respect to, such Letter of Credit,

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

          (c)  upon the termination of the Total Commitment, or the acceleration
     of the Reimbursement Obligations with respect to all Letters of Credit in
     accordance with (S)16, an amount equal to the then Maximum Drawing Amount
     on all Letters of Credit, which amount shall be held by the Agent for the
     benefit of the Banks and the Agent as cash collateral for all Reimbursement
     Obligations.

     Each such payment shall be made to the Agent at the Agent's Head Office in
immediately available funds.  Interest on any and all amounts remaining unpaid
by the Borrower under this (S)5.2 at any time from the date such amounts become
due and payable (whether as stated in this (S)5.2, by acceleration or otherwise)
until payment in full (whether before or after judgment) shall be payable to the
Agent on demand at the rate specified in (S)6.11 for overdue principal on the
Revolving Credit Loans.  Cash collateral held by the Agent pursuant to this
(S)5.2 shall, at the written request of the Borrower, be invested (at the
Borrower's risk) in overnight or other short term investments reasonably
acceptable to the Agent.  The Agent shall maintain a perfected security interest
in such investments in a manner satisfactory to it.  Interest or other earnings
on such investments shall constitute additional cash collateral but shall be
released to the Borrower at its request from time to time, to the extent that
the amount of cash collateral exceeds the amount required by this (S)5.2.

     5.3.  Letter of Credit Payments.
           -------------------------

     If any draft shall be presented or other demand for payment shall be made
under any Letter of Credit, the Agent shall notify the Borrower of the date and
amount of the draft presented or demand for payment and of the date and time
when it expects to pay such draft or honor such demand for payment.  If the
Borrower fails to reimburse the Agent as provided in (S)5.2 on or before the
date that such draft is paid or other
<PAGE>

                                      -41-

payment is made by the Agent, the Agent may at any time thereafter notify the
Banks of the amount of any such Unpaid Reimbursement Obligation. No later than
3:00 p.m. (Boston time) on the Business Day next following the receipt of such
notice, each Bank shall make available to the Agent, at its Head Office, in
immediately available funds, such Bank's Revolving Credit Loan Commitment
Percentage of such Unpaid Reimbursement Obligation, together with an amount
equal to the product of (a) the average, computed for the period referred to in
clause (c) below, of the weighted average interest rate paid by the Agent for
federal funds acquired by the Agent during each day included in such period,
times (b) the amount equal to such Bank's Revolving Credit Loan Commitment
-----
Percentage of such Unpaid Reimbursement Obligation, times (c) a fraction, the
                                                    -----
numerator of which is the number of days that elapse from and including the date
the Agent paid the draft presented for honor or otherwise made payment to the
date on which such Bank's Revolving Credit Loan Commitment Percentage of such
Unpaid Reimbursement Obligation shall become immediately available to the Agent,
and the denominator of which is 360. All such payments shall constitute a
Revolving Credit Loan made to the Borrower (irrespective of the satisfaction by
the Borrower of the conditions set forth in (S)13 hereof or the requirement of
the Borrower to deliver a Loan Request pursuant to (S)2.6 hereof). The
responsibility of the Agent to the Borrower and the Banks shall be only to
determine that the documents (including each draft) delivered under each Letter
of Credit in connection with such presentment shall be in conformity on their
face in all material respects with such Letter of Credit.

     5.4.  Obligations Absolute.
           --------------------

     The Borrower's obligations under this (S)5 shall be absolute and
unconditional under any and all circumstances and irrespective of the occurrence
of any Default or Event of Default or any condition precedent whatsoever or any
setoff, counterclaim or defense to payment which the Borrower may have or have
had against the Agent, any Bank or any beneficiary of a Letter of Credit.  The
Borrower further agrees with the Agent and the Banks that  the Agent and the
Banks shall not be responsible for, and the Borrower's Reimbursement Obligations
under (S)5.2 shall not be affected by, among other things, the validity or
genuineness of documents or of any endorsements thereon, even if such documents
should in fact prove to be in any or all respects invalid, fraudulent or forged,
or any dispute between or among the Borrower, the beneficiary of any Letter of
Credit or any financial institution or other party to which any Letter of Credit
may be transferred or any claims or defenses whatsoever of the Borrower against
the beneficiary of any Letter of Credit or any such transferee.  The Agent and
the Banks shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit.  The Borrower agrees that
any action taken or omitted by the Agent or any Bank under or in connection with
each Letter of Credit and the related drafts and documents, if done in good
faith, shall be binding upon the Borrower and shall not result in any liability
on the part of the Agent or any Bank to the Borrower, subject, however, to the
last sentence of (S)5.3.

     5.5.  Reliance by Issuer.
           ------------------

     To the extent not inconsistent with (S)5.4, the Agent shall be entitled to
rely, and shall be fully protected in relying upon, any Letter of Credit, draft,
writing, resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, telex or teletype message, statement, order or other
document believed by it to be genuine and correct and to have been signed, sent
or made by the proper Person or Persons and upon advice and statements of legal
counsel, independent accountants and other experts selected by the Agent.  The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement unless it shall first have received such advice or concurrence of
the Majority Banks as it
<PAGE>

                                      -42-

reasonably deems appropriate or it shall first be indemnified to its reasonable
satisfaction by the Banks against any and all liability and expense which may be
incurred by it by reason of taking or continuing to take any such action. The
Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement in accordance with a request of the Majority Banks,
and such request and any action taken or failure to act pursuant thereto shall
be binding upon the Banks and all future holders of the Revolving Credit Loans
or of a Letter of Credit Participation.

     5.6.  Letter of Credit Fee.
           --------------------

     The Borrower shall pay to the Agent a fee (in each case, a "Letter of
Credit Fee") in respect of each standby Letter of Credit issued pursuant to this
Credit Agreement, equal to the Applicable Margin at the date of issuance,
extension or renewal of such Letter of Credit multiplied by the face amount of
each such Letter of Credit, plus an issuance fee in respect of each standby
                            ----
Letter of Credit equal to 1/8% on the face amount of each such Letter of Credit
(the "Standby Issuance Fee"), and the Agent shall in turn remit to each Bank its
pro rata portion of such Letter of Credit Fee (but not the Standby Issuance
--------
Fee).  The Letter of Credit Fee for each Letter of Credit shall be payable
quarterly in arrears on the last Business Day of each calendar quarter then
ending.  In addition, the Borrower shall pay to the Agent, for its own account,
the Agent's standard issuance, processing, negotiation, amendment and
administrative fees, determined in accordance with customary fees and charges
for similar facilities.

     6.  CERTAIN GENERAL PROVISIONS.
         --------------------------

     6.1.  Fees Payable to Agent.
           ---------------------

          6.1.1.  Amendment Fee.
                  --------- ---

          The Borrower shall pay to the Agent for the account of the Banks, on
     the Effective Date, an amendment fee in the amount of 0.25% of the Exposure
     of each Bank (after giving effect to the reduction in the Total Commitment
     contemplated by this Credit Agreement) that approved this Credit Agreement
     on or before May 14, 2001 and 0.10% of each other Bank's Exposure.

          6.1.2.  Agent's Fee.
                  ------- ---

          The Borrower shall pay to the Agent certain fees as set forth in the
     letter agreement dated as of the Effective Date between the Borrower and
     the Agent.

     6.2.  Payments to Agent.
           -----------------

     All payments of principal, interest, Reimbursement Obligations, commitment
fees, Letter of Credit Fees and any other amounts due hereunder or under any of
the other Loan Documents shall be made to the Agent, for the respective accounts
of the Banks and the Agent, at the Agent's Head Office or at such other location
in the Boston, Massachusetts, area that the Agent may from time to time
designate, in each case in immediately available funds.  All such payments may
be made by debiting an account of the Borrower with the Agent containing
sufficient funds to make such payment; and the Borrower hereby authorizes the
Agent to debit any such account to make payments hereunder when due

     6.3.  Taxes.
           -----

     (a) Any and all payments by the Borrower to each Bank or the Agent under
this Credit Agreement  shall be made free and clear of, and without deduction or
withholding for, any Taxes.  In addition, the Borrower shall pay all Other
Taxes.
<PAGE>

                                      -43-

     (b)  To the fullest extent permitted by applicable law, the Borrower agrees
to indemnify and hold harmless each Bank and the Agent for the full amount of
Taxes and Other Taxes (including any Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this (S)6.3) paid by such Bank or the
Agent and any liability (including penalties, interest, additions to tax and
expenses) arising therefrom or with respect thereto, whether or not such Taxes
or Other Taxes were correctly or legally asserted.  Payment under this
indemnification shall be made within thirty (30) days after the date the Bank or
the Agent makes written demand therefor in accordance with this (S)6.3.

     (c)  If the Borrower shall be required by law to deduct or withhold any
Taxes or Other Taxes from or in respect of any sum payable hereunder to any Bank
or the Agent, then: (i) the sum payable shall be increased as necessary so that
after making all required deductions and withholdings (including deductions and
withholdings applicable to additional sums payable under this (S)6.3) such Bank
or the Agent, as the case may be, receives an amount equal to the sum it would
have received had no such deductions or withholdings been made; (ii) the
Borrower shall make such deductions and withholdings; and (iii)  the Borrower
shall pay the full amount deducted or withheld to the relevant taxing authority
or other authority in accordance with applicable law.

     (d)  Notwithstanding anything to the contrary contained in this Credit
Agreement, each of the Borrower and the Agent shall be entitled, to the extent
it is required to do so by law, to deduct or withhold income or other similar
taxes imposed by the United States of America from interest, fees or other
amounts payable hereunder for the account of any Bank (without the payment by
the Borrower of increased amounts to such Bank pursuant to clause (a), (b) or
(c) above) other than a Bank (i) which is a domestic corporation (as such term
is defined in Section 7701 of the Code) for federal income tax purposes or (ii)
which has the Prescribed Forms on file with the Borrower and the Agent for the
applicable year, provided that if the Borrower shall so deduct or withhold any
                 --------
such taxes, it shall provide a statement to the Agent and such Bank, setting
forth the amount of such taxes so deducted or withheld, the applicable rate and
any other information or documentation which such Bank or the Agent may
reasonably request for assisting such Bank or the Agent to obtain any allowable
credits or deductions for the taxes so deducted or withheld in the jurisdiction
or jurisdictions in which such Bank is subject to tax.

     (e)  Within thirty (30) days after the date of any payment by the Borrower
of Taxes or Other Taxes, the Borrower shall furnish the Agent the original or a
certified copy of a receipt evidencing payment thereof, or other evidence of
payment satisfactory to the Agent.  Should any Bank or the Agent ever receive
any refund, credit or deduction from any taxing authority to which such Bank or
the Agent would not be entitled but for the payment by the Borrower of Taxes as
required by this (S)6.3 (it being understood that the decision as to whether or
not to claim, and if claimed, as to the amount of any such refund, credit or
deduction shall be made by such Bank or the Agent in its sole discretion), such
Bank or the Agent, as the case may be, thereupon shall repay to the Borrower an
amount with respect to such refund, credit or deduction equal to any net
reduction in taxes actually obtained by such Bank or the Agent, as the case may
be, and determined by such Bank or the Agent, as the case may be, to be
attributable to such refund, credit or deduction.

     (f)  Each Bank shall use its reasonable best efforts (consistent with its
internal policies and legal and regulatory restrictions) to select a
jurisdiction for its lending office or change the jurisdiction of its lending
office, as the case may be, so as to avoid the imposition of any Taxes
<PAGE>

                                      -44-

or Other Taxes or to eliminate any such additional payment by the Borrower which
may thereafter accrue; provided that no such selection or change shall be made
                       --------
if, in the judgment of such Bank, such selection or change would be
disadvantageous to such Bank.

     6.4.  Computations.
           ------------

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

     6.5.  Inability to Determine Eurodollar Rate.
           --------------------------------------

     In the event, prior to the commencement of any Interest Period relating to
any Eurodollar Rate Loan, the Agent shall determine that adequate and reasonable
methods do not exist for ascertaining the Eurodollar Rate that would otherwise
determine the rate of interest to be applicable to any Eurodollar Rate Loan
during any Interest Period, the Agent shall forthwith give notice of such
determination (which shall be conclusive and binding on the Borrower and the
Banks) to the Borrower and the Banks.  In such event (a) any Loan Request,
Advance Request or Conversion Request with respect to Eurodollar Rate Loans
shall be automatically withdrawn and shall be deemed a request for Base Rate
Loans, (b) each Eurodollar Rate Loan will automatically, on the last day of the
then current Interest Period relating thereto, become a Base Rate Loan, and (c)
the obligations of the Banks to make Eurodollar Rate Loans shall be suspended
until the Agent determines that the circumstances giving rise to such suspension
no longer exist, whereupon the Agent shall so notify the Borrower and the Banks.

     6.6.  Illegality.
           ----------

     Notwithstanding any other provisions herein, if any present or future law,
regulation, treaty or directive or change in the interpretation or application
thereof shall make it unlawful for any Bank to make or maintain Eurodollar Rate
Loans, such Bank shall forthwith give notice of such circumstances to the
Borrower and the other Banks and thereupon (a) the commitment of such Bank to
make Eurodollar Rate Loans or convert Loans of another Type to Eurodollar Rate
Loans shall forthwith be suspended and (b) such Bank's Loans then outstanding as
Eurodollar Rate Loans, if any, shall be converted automatically to Base Rate
Loans on the last day of each Interest Period applicable to such Eurodollar Rate
Loans or within such earlier period as may be required by law.  The Borrower
hereby agrees promptly to pay the Agent for the account of such Bank, upon
demand by such Bank, any additional amounts necessary to compensate such Bank
for any costs incurred by such Bank in making any conversion in accordance with
this (S)6.6, including any interest or fees payable by such Bank to lenders of
funds obtained by it in order to make or maintain its Eurodollar Loans
hereunder.

     6.7.  Additional Costs, etc.
           ---------------------

     If any present or future applicable law, which expression, as used herein,
includes statutes, rules and regulations thereunder and interpretations thereof
by any competent court or by any governmental or other regulatory body or
official charged with the administration or the interpretation thereof and
requests, directives, instructions and notices
<PAGE>

                                      -45-

at any time or from time to time hereafter made upon or otherwise issued to any
Bank or the Agent by any central bank or other fiscal, monetary or other
authority (whether or not having the force of law), shall:

          (a)    impose or increase or render applicable (other than to the
     extent specifically provided for in (S)6.8 or elsewhere in this Credit
     Agreement) any special deposit, reserve, assessment, liquidity, capital
     adequacy or other similar requirements (whether or not having the force of
     law) against assets held by, or deposits in or for the account of, or loans
     by, or letters of credit issued by, or commitments of an office of any
     Bank, or

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

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

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

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

     then, and in each such case, the Borrower will, upon demand made by such
Bank or (as the case may be) the Agent at any time and from time to time and as
often as the occasion therefor may arise, pay to such Bank or the Agent such
additional amounts as will be sufficient to compensate such Bank or the Agent
for such additional cost, reduction, payment or foregone interest or
Reimbursement Obligation or other sum; provided, however, the Borrower shall not
                                       --------  -------
be liable for any increased amounts incurred or accrued more than ninety (90)
days prior to the giving by such Bank or (as the case may be) the Agent to the
Borrower of the demand for such increased amounts.

     6.8.  Capital Adequacy.
           ----------------

     If any Bank or the Agent determines after the date hereof that (a) the
adoption of or change in any law, governmental rule, regulation, policy,
guideline or directive (whether or not having the force of law) regarding
capital requirements for banks or bank holding companies or any change in the
interpretation or application thereof by a court or governmental authority with
appropriate jurisdiction, or (b) compliance by such Bank or the Agent or any
corporation controlling such Bank or the Agent with any law, governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law) of any such entity regarding capital adequacy, has the effect of reducing
the return on such Bank's or the Agent's commitment with respect to any Loans to
a level below that which such Bank or the Agent could have achieved but for such
adoption, change or compliance (taking into
<PAGE>

                                      -46-

consideration such Bank's or the Agent's then existing policies with respect to
capital adequacy and assuming full utilization of such entity's capital) by any
amount deemed by such Bank or (as the case may be) the Agent to be material,
then such Bank or the Agent may notify the Borrower of such fact. To the extent
that the amount of such reduction in the return on capital is not reflected in
the Base Rate, the Borrower agrees to pay such Bank or (as the case may be) the
Agent for the amount of such reduction in the return on capital as and when such
reduction is determined upon presentation by such Bank or (as the case may be)
the Agent of a certificate in accordance with (S)6.9 hereof. Each Bank shall
allocate such cost increases among its customers in good faith and on an
equitable basis. The Borrower shall not be liable for any amounts pursuant to
this (S)6.8 incurred or accruing more than ninety (90) days prior to the
presentation of such certificate.

     6.9.  Certificate.
           -----------

     A certificate setting forth any additional amounts payable pursuant to
(S)(S)6.7 or 6.8 and a brief explanation of such amounts which are due,
submitted by any Bank or the Agent to the Borrower, shall be conclusive, absent
manifest error, that such amounts are due and owing.

     6.10.  Indemnity.
            ---------

     The Borrower agrees to indemnify each Bank and to hold each Bank harmless
from and against any loss, cost or expense (including with respect to the
Applicable Margin and fees owing to the Agent or any Bank) that such Bank may
sustain or incur as a consequence of (a) default by the Borrower in payment of
the principal amount of or any interest on any Eurodollar Rate Loans as and when
due and payable, including any such loss or expense arising from interest or
fees payable by such Bank to lenders of funds obtained by it in order to
maintain its Eurodollar Rate Loans, (b) default by the Borrower in making a
borrowing or conversion after the Borrower has given (or is deemed to have
given) a Loan Request, notice (in the case of all or any portion of Term Loan A
pursuant to (S)4.1.4(b) or Term Loan B pursuant to (S)4.2.4(b) or a Conversion
Request relating thereto in accordance with (S)2.6, (S)2.7, (S)4.1.4(b) or
(S)4.2.4(b)), or (c) the making of any payment of a Eurodollar Rate Loan or the
making of any conversion of any such Loan to a Base Rate Loan on a day that is
not the last day of the applicable Interest Period with respect thereto,
including interest or fees payable by such Bank to lenders of funds obtained by
it in order to maintain any such Loans.

     6.11.  Interest After Default.
            ----------------------

          6.11.1.  Overdue Amounts.
                   ---------------

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

          6.11.2.  Amounts Not Overdue.
                   -------------------

          During the continuance of a Default or an Event of Default, the
     principal amount of the Loans not overdue shall, until such Default or
     Event of Default has been cured or remedied or such Default or event of
     Default has been waived by the Majority Banks pursuant to (S)28, bear
     interest at a rate per annum equal to the two percent (2%) above the rate
     of interest otherwise applicable to such Loans pursuant to (S)2.5,
     (S)4.1.4, and (S)4.2.4.
<PAGE>

                                      -47-

     6.12.  Interest Limitation.
            --------------------

     It is the intention of the parties hereto that each Bank shall conform
strictly to usury laws applicable to it.  Accordingly, if the transactions
contemplated hereby would be usurious as to any Bank under laws applicable to it
(including the laws of the United States of America or any other jurisdictions
whose laws may be mandatorily applicable to such Bank), then, in that event,
notwithstanding anything to the contrary in the Loan Documents, the Credit
Agreement or any other agreements entered into in connection with or as security
for the Obligations, it is agreed as follows:  (a) the aggregate of all
consideration which constitutes interest under laws applicable to any Bank that
is contracted for, taken, reserved, charged or received by such Bank under the
Loan Documents, the Credit Agreement or any other agreements entered into in
connection with or as security for the Obligations or otherwise in connection
with the Obligations shall under no circumstances exceed the maximum amount
allowed by such applicable law, and any excess shall be cancelled automatically
and if theretofore paid shall be credited by such Bank on the principal amount
of the Indebtedness (or, to the extent that the principal amount of the
Indebtedness shall have been or would thereby be paid in full, refunded by such
Bank to the Borrower); and (b) in the event that the maturity of the Loans is
accelerated, or in the event of any required or permitted prepayment, then such
consideration that constitutes interest under law applicable to any Bank may
never include more than the maximum amount allowed by such applicable law, and
excess interest, if any, provided for in this Credit Agreement or otherwise
shall be cancelled automatically by such Bank as of the date of such
acceleration or prepayment and, if therefore paid, shall be credited by such
Bank on the principal amount of the Indebtedness (or, to the extent that the
principal amount of the Indebtedness shall have been or would thereby be paid in
full, refunded by such Bank to the Borrower).  All sums paid or agreed to be
paid to any Bank for the use, forbearance or detention of sums due hereunder
shall, to the extent permitted by laws applicable to such Bank, be amortized,
prorated, allocated and spread through the term of the Loans until payment in
full so that the rate or amount of interest on account of any Loans does not
exceed the maximum amount allowed by such applicable law.  If at any time and
from time to time (a) the amount of interest payable to any Bank on any date
shall be computed at the highest lawful rate applicable to such Bank pursuant to
this paragraph and (b) in respect of any subsequent interest computation period
the amount of interest otherwise payable to such Bank would be less than the
amount of interest payable to such Bank computed at the highest lawful rate
applicable to such Bank, then the amount of interest payable to such Bank in
respect of such subsequent interest computation period shall continue to be
computed at the highest lawful rate applicable to such Bank until the total
amount of interest payable to such Bank shall equal the total amount of interest
which would have been payable to such Bank if the total amount of interest had
been computed without giving effect to this paragraph.

     To the extent that Article 5069-1.04 of the Texas Revised Civil Statutes is
relevant to any Bank for the purpose of determining the highest lawful rate,
each such Bank hereby elects to determine the applicable rate ceiling under such
Article by the indicated (weekly) rate ceiling from time to time in effect.

     6.13.  Replacement of Bank.
            -------------------

     In the event that any Bank makes a demand for payment pursuant to
(S)(S)6.3, 6.7 or 6.8, or terminates the Commitment of the Bank to make, or
convert Loans of another Type to, Eurodollar Rate Loans pursuant to (S)6.6, the
Borrower shall have the right, if no Default or Event of Default then exists, to
replace such Bank in accordance with this (S)6.13.  If the Borrower determines
to replace such Bank, the Borrower shall have the right to replace such Bank
with an entity that is an Eligible Assignee (a "Replacement Bank"); provided
                                                ----------- ----
<PAGE>

                                      -48-

that such Replacement Bank, (a) shall be reasonably acceptable to the Agent, (b)
shall unconditionally offer in writing (with a copy to the Agent) to purchase
all of such Bank's rights under the Loan Documents and interest in the Loans
owing to such Bank and the Reimbursement Obligations owing to such Bank, in each
case without recourse, at the principal amount of such Obligations plus interest
and fees accrued thereon to the date of such purchase on a date therein
specified, and (c) shall execute and deliver to the Agent an Assignment and
Acceptance in accordance with (S)21 hereof.  Upon satisfaction of the
requirements set forth in the second sentence of this (S)6.13, acceptance of
such offer to purchase by the Bank to be replaced, payment to such Bank of the
purchase price in immediately available funds, and the payment by the Borrower
of all requested costs accruing to the date of purchase which the Borrower is
obligated to pay under (S)6.10 and all other amounts owed by the Borrower to
such Bank (other than the principal of and interest on the Obligations of such
Bank purchased by the Replacement Bank), and execution of the Assignment and
Acceptance by all parties thereto in accordance with (S)21 hereof, the
Replacement Bank shall constitute a "Bank" hereunder with a Commitment as so
specified and the Bank being so replaced shall no longer constitute a "Bank"
hereunder and shall thereupon be released from any and all liabilities in
respect of the Credit Agreement and the other Loan Documents.  If, however, (i)
a Bank accepts such an offer and such proposed Replacement Bank fails to
purchase such rights and interests on such specified date in accordance with the
terms of such offer and to execute an Assignment and Acceptance, the Borrower
shall continue to be obligated to pay the increased costs or additional amounts
due to such Bank pursuant to (S)(S)6.3, 6.7 or 6.8 (if a demand for repayment of
increased costs or additional amounts pursuant to any of such Sections is the
basis for the proposed replacement), as the case may be, or (ii) the Bank
proposed to be replaced fails to accept such purchase offer, the Borrower (if
the basis for the proposed replacement is a demand for payment of increased
costs or additional amounts pursuant to (S)(S)6.3, 6.7 or 6.8) shall not be
obligated to pay to such Bank such increased costs or additional amounts
incurred or accrued from and after the date of such purchase offer.

     7.  COLLATERAL SECURITY AND GUARANTIES.
         ----------------------------------

     7.1.  Security of Borrower.
           --------------------

     The Obligations shall continue to be equally and ratably secured by (a) a
perfected first priority security interest in or lien on the Collateral (subject
only to Permitted Liens entitled to priority under applicable law) pursuant to
the terms of the Security Documents to which the Borrower is a party, and (b) a
pledge by the Borrower of (i) one hundred percent (100%) of the capital stock of
each of its Domestic Subsidiaries, and (ii) sixty-six percent (66%) of the
capital stock of each of its Foreign Subsidiaries, pursuant to the terms of the
Stock Pledge Agreement, provided, that the Borrower will not be required to
                        --------
pledge the capital stock of any Subsidiary which is an Immaterial Subsidiary.

     7.2.  Guaranties and Security of Domestic Subsidiaries.
           ------------------------------------------------

     The Obligations shall also continue to be guaranteed pursuant to the terms
of the Guaranty by each of the Domestic Subsidiaries of the Borrower (unless
such Domestic Subsidiary is an Immaterial Subsidiary).  The obligations of the
Domestic Subsidiaries under the Guaranty shall in turn continue to be equally
and ratably secured by a perfected first priority security interest in or lien
on the Collateral (subject only to Permitted Liens entitled to priority under
applicable law) pursuant to the terms of the Security Documents to which such
Domestic Subsidiary is a party.

     7.3.  Guaranties of Holdings and Petro, Inc.
           -------------------------------------

     The Obligations shall also continue to be guaranteed pursuant to the terms
of the Holdings Guaranty and the General Partner Guaranty.
<PAGE>

                                      -49-

The Obligations of Holdings under the Holdings Guaranty shall in turn continue
to be solely secured by a perfected first priority security interest in all of
the partnership interests of the Borrower owned by Holdings pursuant to the
Partnership Pledge Agreement to which it is a party. The Obligations of Petro,
Inc. under the General Partner Guaranty shall in turn continue to be solely
secured by a perfected first priority security interest in all of the
partnership interests of the Borrower owned by Petro, Inc. pursuant to the
Partnership Pledge Agreement to which it is a party.

     particular capital requirements of the business conducted by Holdings and

     8.16.  Employee Benefit Plans.
            ----------------------

          8.16.1.  In General.
                   ----------

          Except as set forth on Schedule 8.16 hereto, each Employee Benefit
                                 -------------
     Plan has been maintained and operated in compliance in all material
     respects with the provisions of ERISA and, to the extent applicable, the
     Code, including but not
<PAGE>

                                      -54-

     limited to the provisions thereunder respecting prohibited transactions.
     The Borrower has heretofore delivered or made available to the Agent the
     most recently completed annual report, Form 5500, with all required
     attachments, and actuarial statement required to be submitted under
     (S)103(d) of ERISA, with respect to each Guaranteed Pension Plan, if any.

          8.16.2.  Terminability of Welfare Plans.
                   ------------------------------

          Each Employee Benefit Plan which is an employee welfare benefit plan
     within the meaning of (S)3(1) or (S)3(2)(B) of ERISA may be terminated by
     the Borrower or an ERISA Affiliate, as appropriate, at any time (or at any
     time subsequent to the expiration of any applicable bargaining agreement)
     in the discretion of the Borrower or such ERISA Affiliate, without material
     liability to any Person.

          8.16.3.  Guaranteed Pension Plans.
                   ------------------------

          Each contribution required to be made to a Guaranteed Pension Plan,
     whether required to be made to avoid the incurrence of an accumulated
     funding deficiency, the notice or lien provisions of (S)302(f) of ERISA, or
     otherwise, has been timely made.  No waiver of an accumulated funding
     deficiency or extension of amortization periods has been received with
     respect to any Guaranteed Pension Plan.  No liability to the PBGC (other
     than required insurance premiums, all of which have been paid) has been
     incurred by the Borrower or any ERISA Affiliate with respect to any
     Guaranteed Pension Plan and there has not been any ERISA Reportable Event,
     or any other event or condition which presents a material risk of
     termination of any Guaranteed Pension Plan by the PBGC. Based on the latest
     valuation of each Guaranteed Pension Plan (which in each case occurred
     within twelve months prior to the date of this representation), and on the
     actuarial methods and assumptions employed for that valuation, the
     aggregate benefit liabilities of all such Guaranteed Pension Plans within
     the meaning of (S)4001 of ERISA did not exceed the aggregate value of the
     assets of all such Guaranteed Pension Plans by more than $1,000,000,
     disregarding for this purpose the benefit liabilities and assets of any
     Guaranteed Pension Plan with assets in excess of benefit liabilities.

          8.16.4.  Multiemployer Plans.
                   -------------------

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

     8.17.  Regulations U and X.
            -------------------

     The proceeds of the Revolving Credit Loans and the Term Loans shall be used
solely to convert the Obligations under the Original Credit Agreement to
Obligations hereunder, and thereafter for working capital and partnership and
general corporate purposes and Capital Expenditures (including making
Investments in Subsidiaries to permit such Subsidiaries to make Capital
Expenditures as permitted hereunder) (subject to the limitations set forth in
(S)(S)9.12 and 11.7 hereof).  The Borrower will obtain Letters of Credit solely
for partnership and general corporate purposes.  No portion of any Loan is to be
used, and no portion of any Letter of Credit is to be obtained, for the purpose
of purchasing or carrying any

present condition and usage of the Real Estate and the operations conducted

     investigation, removal or other response action pursuant to any
     Environmental Law; or (iii) that it is or shall be a named party to any
     claim, action, cause of action, complaint, or legal or administrative
     proceeding (in each case, contingent or otherwise) arising out of any third
     party's incurrence of costs, expenses, losses or damages of any kind
     whatsoever in connection with the release of Hazardous Substances which
     claim, cause of action or proceeding could have any of the effects
     described in (S)8.7;

          (c)  during the period of the Borrower's or its Subsidiaries'
     ownership, and to the best of the Borrower's knowledge with respect to all

     Substances on,
<PAGE>

                                      -56-

     upon, into or from the properties of the Borrower or its Subsidiaries,
     which releases would have a material adverse effect on the value of any of
     the Real Estate or adjacent properties or the environment; (iv) to the best
     of the Borrower's knowledge, there have been no releases on, upon, from or
     into any real property in the vicinity of any of the Real Estate which,

and promptly submit to the Agent for its approval a revised Construction Budget.
No further Revolving Credit Loans for such Project need be made by the Agent

forthwith terminate and each of the Banks shall be relieved of all further
obligations to make Loans to the Borrower and the Agent shall be relieved of all
further obligations to issue, extend or renew Letters of Credit.  If any other
Event of Default shall have occurred and be continuing, the Agent may and, upon
the request of the Majority Banks shall, by notice to the Borrower, terminate
the unused portion of the Total Commitment hereunder, and upon such notice being
given such unused portion of the Total Commitment hereunder shall terminate
immediately and each of the Banks shall be relieved of all further obligations
to make Loans and the Agent shall be relieved of all further obligations to
issue, extend or renew Letters of Credit.  No termination of the Total
Commitment hereunder shall relieve Holdings, the Borrower or any of its
Subsidiaries of any of the Obligations (other than as provided in (S)2.3).

     14.3.  Remedies.
            --------

     In case any one or more of the Events of Default shall have occurred and be
continuing, and whether or not the Banks shall have accelerated the maturity of
the Loans pursuant to (S)14.1, each Bank, if owed any amount with respect to the
Loans or the Reimbursement Obligations, may, with the consent of the Majority
Banks but not otherwise, proceed to protect and enforce its rights by suit in
equity, action at law or other appropriate proceeding, whether for the specific
performance of any covenant or agreement contained in this Credit Agreement and
the other Loan Documents or any instrument pursuant to which the Obligations to
such Bank are evidenced, including as permitted by applicable law the obtaining
of the ex parte appointment of a receiver, and, if such amount shall have become
       -- -----
due, by declaration or otherwise, proceed to enforce the payment thereof or any
other legal or equitable right of such Bank.  No remedy herein conferred upon
any Bank or the Agent or the holder of any Loans or purchaser of any Letter of
Credit Participation is intended to be exclusive of any other remedy and each
and every remedy shall be cumulative and shall be in addition to every
<PAGE>

                                      -91-

other remedy given hereunder or now or hereafter existing at law or in equity or
by statute or any other provision of law.

     14.4.  Distribution of Collateral Proceeds.
            -----------------------------------

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

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

          (b)  Second, to all other Obligations in such order or preference as
               ------
     the Majority Banks may determine; provided, however, that distributions in
                                       --------  -------
     respect of such obligations shall be made (i) pari passu among Obligations
                                                   ---- -----
     with respect to the Agent's fee payable pursuant to (S)6.2 and all other
     Obligations and (ii) Obligations owing to the Banks with respect to each
     type of Obligation such as interest, principal, fees and expenses, shall be
     made among the Banks pro rata; and provided, further, that the Agent may in
                          --- ----      --------  -------
     its discretion make proper allowance to take into account any Obligations
     not then due and payable;

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

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

     15.  SETOFF.
          ------

     Regardless of the adequacy of any collateral, during the continuance of any
Event of Default, any deposits or other sums credited by or due from any of the
Banks to the Borrower and any securities or other property of the Borrower in
the possession of such Bank may be applied to or set off by such Bank against
the payment of Obligations and any and all other liabilities, direct, or
indirect, absolute or contingent, due or to become due, now existing or
hereafter arising, of the Borrower to such Bank under the Loan Documents.  Each
of the Banks agrees with each other Bank that (a) if an amount to be set off is
to be applied to Indebtedness of the Borrower to such Bank, such amount shall be
applied ratably to such other Indebtedness owed to such Bank, and (b) if such
Bank shall receive from the Borrower, whether by voluntary payment, exercise of
the right of setoff, counterclaim, cross action, enforcement of the claim
constituting Obligations owed to such Bank by proceedings against the Borrower
at law or in
<PAGE>

                                      -92-

equity or by proof thereof in bankruptcy, reorganization, liquidation,
receivership or similar proceedings, or otherwise, and shall retain and apply to
the payment of the Obligations owed to such Bank any amount in excess of its
ratable portion of the payments received by all of the Banks with respect to
the Obligations owed to all of the Banks, such Bank will make such disposition
and arrangements with the other Banks with respect to such excess, either by
way of distribution, pro tanto assignment of claims, subrogation or otherwise
                     --- -----
as shall result in each Bank receiving in respect of the Obligations owed it,
its proportionate payment as contemplated by this Credit Agreement; provided
                                                                    --------
that if all or any part of such excess payment is thereafter recovered from such
Bank, such disposition and arrangements shall be rescinded and the amount
restored to the extent of such recovery, but without interest.

     16.  THE AGENT.
          ---------

     16.1.  Authorization.
            -------------

          (a)  The Agent is authorized to take such action on behalf of each of
     the Banks and to exercise all such powers as are hereunder and under any of
     the other Loan Documents and any related documents delegated to the Agent,
     together with such powers as are reasonably incident thereto, provided that
                                                                   --------
     no duties or responsibilities not expressly assumed herein or therein shall
     be implied to have been assumed by the Agent.

          (b)  The relationship between the Agent and each of the Banks is that
     of an independent contractor.  The use of the term "Agent" is for
     convenience only and is used to describe, as a form of convention, the
     independent contractual relationship between the Agent and each of the
     Banks.  Nothing contained in this Credit Agreement nor the other Loan
     Documents shall be construed to create an agency, trust or other fiduciary
     relationship between the Agent and any of the Banks.  Neither the Co-Agent
     nor the Documentation Agent shall have any duties or responsibilities under
     this Credit Agreement.

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

     16.2.  Employees and Agents.
            --------------------

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

                                      -93-

any such Persons shall be paid by the Borrower, except in any case where this
Credit Agreement provides that the Borrower is not responsible for costs.

     16.3.  No Liability.
            ------------

     Neither the Agent nor any of its shareholders, directors, officers or
employees nor any other Person assisting them in their duties nor any agent or
employee thereof, shall be liable for any waiver, consent or approval given or
any action taken, or omitted to be taken, in good faith by it or them hereunder
or under any of the other Loan Documents, or in connection herewith or
therewith, or be responsible for the consequences of any oversight or error of
judgment whatsoever, except that the Agent or such other Person, as the case may
be, may be liable for losses due to its willful misconduct or gross negligence.

     16.4.  No Representations.
            ------------------

          16.4.1.  General.
                   -------

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

          16.4.2.  Closing Documentation, etc.
                   --------------------------

          For purposes of determining compliance with the conditions set forth
     in (S)12, each Bank that has executed this Credit Agreement shall be deemed
     to have consented to, approved or accepted, or to be satisfied with, each
     document and matter sent by the Agent or the Arranger to, and received by,
     such Bank for consent, approval, acceptance or satisfaction, or required
     thereunder to be consented to or approved by or acceptable or satisfactory
     to such Bank, unless an officer of the Agent or the Arranger active upon
     the Borrower's account shall have received notice from such Bank prior to
     the Effective Date specifying such Bank's objection thereto and such
     objection shall not have been withdrawn by notice to the Agent or the
     Arranger to such effect on or prior to the Effective Date.

     16.5.  Payments.
            --------
<PAGE>

                                      -94-

          16.5.1.  Payments to Agent.
                   -----------------

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

          16.5.2.  Distribution by Agent.
                   ---------------------

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

          16.5.3.  Delinquent Banks.
                   ----------------

          Notwithstanding anything to the contrary contained in this Credit
     Agreement or any of the other Loan Documents, any Bank that fails (a) to
     make available to the Agent its pro rata share of any Loan or to purchase
                                     --- ----
     any Letter of Credit Participation or (b) to comply with the provisions of
     (S)15 with respect to making dispositions and arrangements with the other
     Banks, where such Bank's share of any payment received, whether by setoff
     or otherwise, is in excess of its pro rata share of such payments due and
                                       --- ----
     payable to all of the Banks, in each case as, when and to the full extent
     required by the provisions of this Credit Agreement, shall be deemed
     delinquent (a "Delinquent Bank") and shall be deemed a Delinquent Bank
     until such time as such delinquency is satisfied.  A Delinquent Bank shall
     be deemed to have assigned any and all payments due to it from the
     Borrower, whether on account of outstanding Loans, Unpaid Reimbursement
     Obligations, interest, fees or otherwise, to the remaining nondelinquent
     Banks for application to, and reduction of, their respective pro rata
                                                                  --- ----
     shares of all outstanding Loans and Unpaid Reimbursement Obligations.  The
     Delinquent Bank hereby authorizes the Agent to distribute such payments to
     the nondelinquent Banks in proportion to their respective pro rata shares
                                                               --- ----
     of all outstanding Loans and Unpaid Reimbursement Obligations.  A
     Delinquent Bank shall be deemed to have satisfied in full a delinquency
     when and if, as a result of application of the assigned payments to all
     outstanding Loans and Unpaid Reimbursement Obligations of the nondelinquent
     Banks, the Banks' respective pro rata shares of all outstanding Loans and
                                  --- ----
     Unpaid Reimbursement Obligations have returned to those in effect
     immediately prior to such delinquency and without giving effect to the
     nonpayment causing such delinquency.

     16.6.  Holders.
            -------

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

     16.7.  Indemnity.
            ---------

     The Banks ratably agree hereby to indemnify and hold harmless the Agent and
its affiliates from and against any and all claims, actions and suits (whether
groundless or otherwise), losses, damages, costs, expenses (including any
expenses for which the Agent or such affiliate has not been reimbursed by the
Borrower as required by (S)17), and
<PAGE>

                                      -95-

liabilities of every nature and character arising out of or related to this
Credit Agreement (including without limitation (S)16.5.2) or any of the other
Loan Documents or the transactions contemplated or evidenced hereby or thereby,
or the Agent's actions taken hereunder or thereunder, except to the extent that
any of the same shall be directly caused by the Agent's or such affiliate's
willful misconduct or gross negligence.

     16.8.  Agent as Bank.
            -------------

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

     16.9.  Resignation.
            -----------

     The Agent may resign at any time by giving sixty (60) days prior written
notice thereof to the Banks and the Borrower.  Upon any such resignation, the
Majority Banks shall have the right to appoint a successor Agent.  Unless a
Default or Event of Default shall have occurred and be continuing, such
successor Agent shall be reasonably acceptable to the Borrower.  If no successor
Agent shall have been so appointed by the Majority Banks and shall have accepted
such appointment within thirty (30) days after the retiring Agent's giving of
notice of resignation, then the retiring Agent may, on behalf of the Banks,
appoint a successor Agent, which shall be a financial institution having a
rating of not less than A or its equivalent by Standard & Poor's Corporation.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder.  After any
retiring Agent's resignation, the provisions of this Credit Agreement and the
other Loan Documents shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as Agent.

     16.10.  Notification of Defaults and Events of Default.
             ----------------------------------------------

     Each Bank hereby agrees that, upon learning of the existence of a Default
or an Event of Default, it shall promptly notify the Agent thereof.  The Agent
hereby agrees that upon receipt of any notice under this (S)16.10 it shall
promptly notify the other Banks of the existence of such Default or Event of
Default.

     16.11.  Duties in the Case of Enforcement.
             ---------------------------------

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

     17.  EXPENSES.

                                      -96-

administration thereof after the occurrence of a Default or Event of Default and
(ii) any litigation, proceeding or dispute whether arising hereunder or
otherwise, in any way related to any Bank's or the Agent's relationship with the

     18.  INDEMNIFICATION.
          ---------------

     The Borrower agrees to indemnify and hold harmless the Arranger, the Agent
and the Banks, and their respective affiliates, officers, directors, agents,
trustees and investment advisors, from and against any and all claims, actions
and suits whether groundless or otherwise, and from and against any and all
liabilities, losses, damages and expenses of every nature and character arising
out of this Credit Agreement or any of the other Loan Documents or the
transactions contemplated hereby including, without limitation, (a) any actual
or proposed use by the Borrower or any of its Subsidiaries of the proceeds of
any of the Loans or Letters of Credit, (b) any actual or alleged infringement of
any patent, copyright, trademark, service mark or similar right of the Borrower
or any of its Subsidiaries comprised in the Collateral, (c) the Borrower or any

threatened release of any Hazardous Substances or any action, suit, proceeding
or investigation brought or threatened with respect to any Hazardous Substances
(including, but not limited to, claims with respect to wrongful death, personal
injury or damage to property), in each case including, without limitation, the
reasonable fees and disbursements of counsel and allocated costs of internal
counsel incurred in connection with any such investigation, litigation or other
proceeding and EXPRESSLY INCLUDING ANY SUCH CLAIM, ACTION OR SUIT ARISING OUT OF
THE ORDINARY, SOLE OR CONTRIBUTORY NEGLIGENCE OF SUCH INDEMNIFIED PERSON (but
excluding such claim, action or suit to the extent attributable to the bad
faith, gross negligence or willful misconduct of, or violation of any law or
regulation by, any such indemnified person). Notwithstanding the foregoing the
Borrower shall not be obligated to indemnify any such Person from any loss
resulting from a dispute solely between or among the Banks and any dispute
between the Agent and a Bank in which the Agent has been finally determined by a
non-appealable court of competent jurisdiction to have acted with gross
negligence or willful misconduct. In litigation, or the preparation therefor,
the Banks and the Agent shall be entitled to select their own counsel and, in
addition to the foregoing indemnity, the Borrower agrees to pay promptly the
reasonable fees and expenses of such counsel; provided, however, the Borrower
shall only be required to pay the reasonable fees and expenses of one such
counsel for all the Banks and the Agent. If, and to the extent that the
obligations of the Borrower under this (S)18 are unenforceable for any reason,
the Borrower hereby agrees to make the maximum contribution to the payment in
satisfaction of such obligations which is permissible under applicable law. The
Borrower shall be entitled to notice of any proceeding in respect of which a
claim for indemnity or contribution will be made and shall be entitled to
participate in the defense of any such proceeding. The failure to provide such
notice shall not discharge or reduce any indemnity or contribution claim except
to the extent that the Borrower has been prejudiced thereby. The covenants
contained in this (S)18 shall survive payment or satisfaction in full of all
other Obligations.

     19.  TREATMENT OF CERTAIN CONFIDENTIAL INFORMATION.
          ---------------------------------------------

     19.1.  Sharing of Information with Section 20 Subsidiary.
            -------------------------------------------------

     The Borrower acknowledges that from time to time financial advisory,
investment banking and other services may be offered or provided to the Borrower

any interest or fees are payable hereunder or under any of the other Loan
Documents for its account, deliver to the Borrower and the Agent certification

income taxes.  If any Reference Bank transfers all of its interest, rights and
obligations under this Credit Agreement, the Agent shall, in consultation with
the Borrower and with the consent of the Borrower and the Majority Banks,
appoint another Bank to act as a Reference Bank hereunder.  Anything contained
in this (S)21 to the contrary notwithstanding, any Bank may at any time pledge

                                             ----- -----
     manifest error) of the principal amount thereof owing and unpaid to such

          2.7.1.  Conversion to Different Type of Revolving Credit Loan.
                  -----------------------------------------------------

          The Borrower may elect from time to time to convert any outstanding
     Revolving Credit Loan to a Revolving Credit Loan of another Type, provided
                                                                       --------
     that (a) with respect to any such conversion of a Eurodollar Rate Loan to a
     Base Rate Loan, the Borrower shall give the Agent at least one (1) Business
     Day's prior written notice of such election; (b) with respect to any such
     conversion of a Base Rate Loan to a Eurodollar Rate Loan, the
<PAGE>

                                      -30-

     Borrower shall give the Agent at least three (3) Eurodollar Business Days'
     prior written notice of such election; (c) with respect to any such
     conversion of a Eurodollar Rate Loan to a Base Rate Loan, such conversion
     shall only be made on the last day of the Interest Period with respect to
     such Eurodollar Rate Loan and (d) no Base Rate Loan may be converted into a
     Eurodollar Rate Loan when any Default or Event of Default has occurred and
     is continuing. On the date on which such conversion is being made each Bank
     shall take such action as is necessary to transfer its applicable
     Commitment Percentage of such Revolving Credit Loans to its Domestic
     Lending Office or its Eurodollar Lending Office, as the case may be. All or
     any part of outstanding Revolving Credit Loans of any Type may be converted
     into a Revolving Credit Loan of another Type as provided herein, provided
                                                                      --------
     that any partial conversion shall be in an aggregate principal amount of
     $500,000 or an integral multiple of $100,000 in excess thereof. Each
     Conversion Request relating to the conversion of a Base Rate Loan to a
     Eurodollar Rate Loan shall specify the Interest Period for such converted
     Eurodollar Rate Loan and shall be irrevocable by the Borrower.

          2.7.2.  Continuation of Type of Revolving Credit Loan.
                  ---------------------------------------------

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

         2.7.3.  Eurodollar Rate Loans.
                 ---------------------

         Any conversion to or from Eurodollar Rate Loans shall be in such
    amounts and be made pursuant to such elections so that, after giving effect
    thereto, the aggregate principal amount of all Eurodollar Rate Loans having
    the same Interest Period shall not be less than $1,000,000 or an integral
    multiple of $100,000 in excess thereof.  In addition, no more than seven (7)
    Eurodollar Rate Loans (in the aggregate including Revolving Credit Loans and
    Term Loans) having different Interest Periods shall be outstanding at any
    one time.

     2.8.  Funds for Revolving Credit Loans.
           --------------------------------

          2.8.1.  Funding Procedures.
                  ------------------

          Not later than 2:00 p.m. (Boston time) on the proposed Drawdown Date
     of any Revolving Credit Loans, each of the Banks will make available to the
     Agent, at the Agent's Head Office, in immediately available funds, the
     amount of such Bank's Commitment Percentage of the amount of the requested
     Revolving Credit Loans.  Upon receipt from each Bank of such amount, and
     upon receipt of the documents required by (S)(S)12 and 13 and the
     satisfaction of the other conditions set forth therein, to the extent
     applicable, the Agent will make available to the Borrower the aggregate
     amount of such Revolving Credit Loans made available to the
<PAGE>

                                      -31-

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

          2.8.2.  Advances by Agent.
                  -----------------

          The Agent may, unless notified to the contrary by any Bank prior to a
     Drawdown Date, assume that such Bank has made available to the Agent on
     such Drawdown Date the amount of such Bank's Commitment Percentage of the
     Revolving Credit Loans to be made on such Drawdown Date, and the Agent may
     (but it shall not be required to), in reliance upon such assumption, make
     available to the Borrower a corresponding amount.  If any Bank makes
     available to the Agent such amount on a date after such Drawdown Date, such
     Bank shall pay to the Agent on demand an amount equal to the product of (a)
     the average computed for the period referred to in clause (c) below, of the
     weighted average interest rate per annum paid by the Agent for federal
     funds acquired by the Agent during each day included in such period, times
                                                                          -----
     (b) the amount of such Bank's Commitment Percentage of such Revolving
     Credit Loans, times (c) a fraction, the numerator of which is the number of
                   -----
     days that elapse from and including such Drawdown Date to the date on which
     the amount of such Bank's Commitment Percentage of such Revolving Credit
     Loans shall become immediately available to the Agent, and the denominator
     of which is 365.  A statement of the Agent submitted to such Bank with
     respect to any amounts owing under this paragraph shall be prima facie
                                                                ----- -----
     evidence of the amount due and owing to the Agent by such Bank.  If the
     amount of such Bank's Commitment Percentage of such Revolving Credit Loans
     is not made available to the Agent by such Bank within four (4) Business
     Days following such Drawdown Date, the Agent shall be entitled to recover
     such amount from the Borrower on demand, with interest thereon at the rate
     per annum applicable to the Revolving Credit Loans made on such Drawdown
     Date.

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

     3.1.  Maturity.
           --------

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

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

     If at any time the sum of the outstanding amount of the Revolving Credit
Loans, the Maximum Drawing Amount and all Unpaid Reimbursement Obligations
exceeds the Total Commitment, then the Borrower shall immediately pay the amount
of such excess to the Agent for the respective accounts of the Banks for
application:  first, to any Unpaid Reimbursement Obligations; second, to the
Revolving Credit Loans; and third, to provide to the Agent cash collateral for
Reimbursement Obligations as contemplated by (S)5.2(b) and (c).  Each payment of
any Unpaid Reimbursement Obligations or prepayment of Revolving Credit Loans
shall be allocated among the Banks, in proportion, as nearly as practicable, to
each Reimbursement Obligation or (as the case may be) the respective unpaid
principal amount of the Revolving Credit Loans owing to such Bank, with
adjustments to the extent practicable to equalize any prior payments or
repayments not exactly in proportion.

                                      -32-

     3.3.  Optional Repayments of Revolving Credit Loans.
           ---------------------------------------------

     The Borrower shall have the right, at its election, to repay the
outstanding amount of the Revolving Credit Loans, as a whole or in part, at any
time without penalty or premium (but subject to (S)6.10).  The Borrower shall
give the Agent, no later than 11:00 a.m., Boston time, on the date of any
proposed prepayment written notice of any proposed prepayment pursuant to this
(S)3.3 of Base Rate Loans, and three (3) Eurodollar Business Days' prior written
notice of any proposed prepayment pursuant to this (S)3.3 of Eurodollar Rate
Loans, in each case specifying the proposed date of prepayment of Revolving
Credit Loans and the principal amount to be prepaid.  Each such partial
prepayment of the Revolving Credit Loans shall be in a minimum aggregate amount
of $250,000 or a whole multiple of $50,000 in excess thereof and shall be
applied, in the absence of instruction by the Borrower, first to the principal
of Base Rate Loans and then to the principal of Eurodollar Rate Loans or both,
at the Agent's option.  Each partial prepayment shall be allocated among the
Banks, in proportion, as nearly as practicable, to the respective unpaid
principal amount of each Bank's Revolving Credit Note, with adjustments to the
extent practicable to equalize any prior repayments not exactly in proportion.

     4.  THE TERM LOANS.

     converted into a Term Loan A, held severally by the Banks in accordance
     with their Commitment Percentages.  On the Conversion Date the Borrower
     shall pay to the Agent for the pro rata accounts of the Banks all interest
                                    --- -----
     accrued to such date on the Revolving Credit Loans so converted, together
     with any Unpaid Reimbursement Obligations, any commitment fees and other
     fees payable to the Agent and the Banks hereunder, and, as soon as
     reasonably practicable after such payment, each Bank shall surrender to the
     Borrower its Revolving Credit Note (if any) and the Borrower shall, if
     requested by such Bank, execute and deliver (i) a Term A Note evidencing
     the amount of the outstanding Revolving Credit Loans so converted, and (ii)
     a new Revolving Credit Note evidencing such Bank's Commitment Percentage of
     the Total Commitment in effect following the Conversion Date.

          4.1.2.  Loan Account.
                  ------------

          (a) The Term Loan A and the Obligations of the Borrower in respect
     thereof shall be evidenced by this Credit Agreement and the Loan Account
     maintained by each Bank with respect to the Term Loan A.  The Borrower

     reasonable satisfaction of the Agent that the Leverage Ratio as at the end
     of such fiscal quarter was less than 4.50:1 and no Default or Event of
     Default has occurred and is continuing, then the amount required to be paid
     hereunder following the end of such fiscal quarter shall be one-half of the
     amount required in the preceding sentence with respect to such fiscal
     quarter. Additionally, in the event that the Leverage Ratio as at the end
     of any fiscal year and as at the end of the first fiscal quarter ending
     thereafter is less than 4.50:1 and no Default or Event of Default has
     occurred and is continuing, payments in respect of Consolidated Excess Cash
     Flow shall only be required on an annual basis. Additionally, with respect

     year, if the Borrower can demonstrate to the reasonable satisfaction of the

     year for which such payment is to be made and (ii) the fiscal quarter
     occurring immediately preceding the date such payment is due and payable
     was less than 4.50:1.00 and (b) no Default or Event of Default has occurred
     and is continuing, then the reference to one hundred percent (100%) in
     clause (d) above shall instead be fifty percent (50%). Such payment shall
     be applied, if such prepayment is made prior to the Conversion Date, to the
     Term Loan B based on the then outstanding amount of the Term Loan B and
     applied against the scheduled installments of principal due in the inverse
     order of maturity, or, if such prepayment is made following the Conversion
     Date, to be applied pro rata to each of the Term Loans based on the then
                         --- ----
     outstanding amounts of the Term Loans and applied against the scheduled
     installments of principal due on the respective Term Loans and applied
     against the scheduled installments of principal due or the respective Term
     Loans in the inverse order of maturity. Following the Conversion Date, or
     if there are no amounts outstanding under the Term Loans, such amounts
     shall be applied to the outstanding Revolving Credit Loans and to
     permanently reduce the Total Commitment by such amount.

          4.4.3.  Application.
                  -----------

          In the event any holder of the Term Loan B elects not to receive any
     prepayments it is otherwise entitled to receive pursuant to this (S)4.4 and
     so notifies the Agent in writing of such election prior to the time such
     payment is due, all such prepayments such holder was otherwise entitled to
     receive pursuant to this (S)4.4 shall be applied to the Term Loan A, or, if
     there are no outstanding amounts due under the Term Loan A, or if such
     payment is made prior to the Conversion Date, then to repay outstanding
     Revolving Credit Loans to the extent of the amounts outstanding under the
     Revolving Credit Loans and to provide cash collateral for the Obligations
     and to permanently reduce the Total Commitment by such amount.  The Agent
     shall promptly notify the Borrower in writing of any such elections.

          Notwithstanding the requirements of (S)(S)4.4.1, 4.4.2, and 4.4.3, no
     repayments under this (S)4.4 shall be applied to reduce the Total
     Commitment to an amount less than
<PAGE>

                                      -39-

     $25,000,000. If any such payment would otherwise be required, it shall be
     applied to repay any outstanding Revolving Credit Loans (or cash
     collateralize Letters of Credit, if any) but not to reduce the Total
     Commitment.

     5.  LETTERS OF CREDIT.
         -----------------

     5.1.  Letter of Credit Commitments.
           ----------------------------

          5.1.1.  Commitment to Issue Letters of Credit.
                  -------------------------------------

          Subject to the terms and conditions hereof and the execution and
     delivery by the Borrower of a letter of credit application on the Agent's
     customary form (a "Letter of Credit Application"), the Agent on behalf of
     the Banks and in reliance upon the agreement of the Banks set forth in
     (S)5.1.4 and upon the representations and warranties of the Borrower
     contained herein, agrees, in its individual capacity, to issue, extend and
     renew for the account of the Borrower one or more standby letters of credit
     (individually, a "Letter of Credit"), in such form as may be requested from
     time to time by the Borrower and agreed to by the Agent; provided, however,
                                                              --------  -------
     that, after giving effect to such request, (a) the sum of the aggregate
     Maximum Drawing Amount and all Unpaid Reimbursement Obligations shall not
     exceed $10,000,000 at any one time and (b) the sum of (i) the Maximum
     Drawing Amount on all Letters of Credit, (ii) all Unpaid Reimbursement
     Obligations, and (iii) the amount of all Revolving Credit Loans outstanding
     shall not exceed the Total Commitment.

          5.1.2.  Letter of Credit Applications.
                  -----------------------------

          Each Letter of Credit Application shall be completed to the
     satisfaction of the Agent.  In the event that any provision of any Letter
     of Credit Application shall be inconsistent with any provision of this
     Credit Agreement, then the provisions of this Credit Agreement shall, to
     the extent of any such inconsistency, govern, it being understood and
     agreed that the provisions of the Letter of Credit Application regarding
     indemnification, set-off, insecurity and default shall be governed by the
     indemnification, set-off, default and remedies provisions of this Credit
     Agreement.

          5.1.3.  Terms of Letters of Credit.
                  --------------------------

          Each Letter of Credit issued, extended or renewed hereunder shall,
     among other things, (a) provide for the payment of sight drafts for honor
     thereunder when presented in accordance with the terms thereof and when
     accompanied by the documents described therein, and (b) have an expiry date
     no later than the date which is fourteen (14) days (or, if the Letter of
     Credit is confirmed by a confirmer or otherwise provides for one or more
     nominated persons, thirty (30) days) prior to the Revolving Credit Loan
     Maturity Date. Each Letter of Credit so issued, extended or renewed shall
     be subject to the Uniform Customs or, in the case of a standby Letter of
     Credit issued on or after January 1, 1999, either the Uniform Customs or
     International Standby Practices.

          5.1.4.  Reimbursement Obligations of Banks.
                  ----------------------------------

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

                                      -40-

          5.1.5.  Participations of Banks.
                  -----------------------

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

     5.2.  Reimbursement Obligation of the Borrower.
           ----------------------------------------

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

          (a)  except as otherwise expressly provided in (S)5.2(b) and (c) and
     subject to the last sentence of (S)5.3, on each date that any draft
     presented under such Letter of Credit is honored by the Agent, or the Agent
     otherwise makes a payment with respect thereto, (i) the amount paid by the
     Agent under or with respect to such Letter of Credit, and (ii) the amount
     of any taxes, fees, charges or other costs and expenses reasonably incurred
     by the Agent or any Bank in connection with any payment made by the Agent
     or any Bank under, or with respect to, such Letter of Credit,

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

          (c)  upon the termination of the Total Commitment, or the acceleration
     of the Reimbursement Obligations with respect to all Letters of Credit in
     accordance with (S)16, an amount equal to the then Maximum Drawing Amount
     on all Letters of Credit, which amount shall be held by the Agent for the
     benefit of the Banks and the Agent as cash collateral for all Reimbursement
     Obligations.

     Each such payment shall be made to the Agent at the Agent's Head Office in
immediately available funds.  Interest on any and all amounts remaining unpaid
by the Borrower under this (S)5.2 at any time from the date such amounts become
due and payable (whether as stated in this (S)5.2, by acceleration or otherwise)
until payment in full (whether before or after judgment) shall be payable to the
Agent on demand at the rate specified in (S)6.11 for overdue principal on the
Revolving Credit Loans.  Cash collateral held by the Agent pursuant to this
(S)5.2 shall, at the written request of the Borrower, be invested (at the
Borrower's risk) in overnight or other short term investments reasonably
acceptable to the Agent.  The Agent shall maintain a perfected security interest
in such investments in a manner satisfactory to it.  Interest or other earnings
on such investments shall constitute additional cash collateral but shall be
released to the Borrower at its request from time to time, to the extent that
the amount of cash collateral exceeds the amount required by this (S)5.2.

     5.3.  Letter of Credit Payments.
           -------------------------

     If any draft shall be presented or other demand for payment shall be made
under any Letter of Credit, the Agent shall notify the Borrower of the date and
amount of the draft presented or demand for payment and of the date and time
when it expects to pay such draft or honor such demand for payment.  If the
Borrower fails to reimburse the Agent as provided in (S)5.2 on or before the
date that such draft is paid or other
<PAGE>

                                      -41-

payment is made by the Agent, the Agent may at any time thereafter notify the
Banks of the amount of any such Unpaid Reimbursement Obligation. No later than
3:00 p.m. (Boston time) on the Business Day next following the receipt of such
notice, each Bank shall make available to the Agent, at its Head Office, in
immediately available funds, such Bank's Revolving Credit Loan Commitment
Percentage of such Unpaid Reimbursement Obligation, together with an amount
equal to the product of (a) the average, computed for the period referred to in
clause (c) below, of the weighted average interest rate paid by the Agent for
federal funds acquired by the Agent during each day included in such period,
times (b) the amount equal to such Bank's Revolving Credit Loan Commitment
-----
Percentage of such Unpaid Reimbursement Obligation, times (c) a fraction, the
                                                    -----
numerator of which is the number of days that elapse from and including the date
the Agent paid the draft presented for honor or otherwise made payment to the
date on which such Bank's Revolving Credit Loan Commitment Percentage of such
Unpaid Reimbursement Obligation shall become immediately available to the Agent,
and the denominator of which is 360. All such payments shall constitute a
Revolving Credit Loan made to the Borrower (irrespective of the satisfaction by
the Borrower of the conditions set forth in (S)13 hereof or the requirement of
the Borrower to deliver a Loan Request pursuant to (S)2.6 hereof). The
responsibility of the Agent to the Borrower and the Banks shall be only to
determine that the documents (including each draft) delivered under each Letter
of Credit in connection with such presentment shall be in conformity on their
face in all material respects with such Letter of Credit.

     5.4.  Obligations Absolute.
           --------------------

     The Borrower's obligations under this (S)5 shall be absolute and
unconditional under any and all circumstances and irrespective of the occurrence
of any Default or Event of Default or any condition precedent whatsoever or any
setoff, counterclaim or defense to payment which the Borrower may have or have
had against the Agent, any Bank or any beneficiary of a Letter of Credit.  The
Borrower further agrees with the Agent and the Banks that  the Agent and the
Banks shall not be responsible for, and the Borrower's Reimbursement Obligations
under (S)5.2 shall not be affected by, among other things, the validity or
genuineness of documents or of any endorsements thereon, even if such documents
should in fact prove to be in any or all respects invalid, fraudulent or forged,
or any dispute between or among the Borrower, the beneficiary of any Letter of
Credit or any financial institution or other party to which any Letter of Credit
may be transferred or any claims or defenses whatsoever of the Borrower against
the beneficiary of any Letter of Credit or any such transferee.  The Agent and
the Banks shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit.  The Borrower agrees that
any action taken or omitted by the Agent or any Bank under or in connection with
each Letter of Credit and the related drafts and documents, if done in good
faith, shall be binding upon the Borrower and shall not result in any liability
on the part of the Agent or any Bank to the Borrower, subject, however, to the
last sentence of (S)5.3.

     5.5.  Reliance by Issuer.
           ------------------

     To the extent not inconsistent with (S)5.4, the Agent shall be entitled to
rely, and shall be fully protected in relying upon, any Letter of Credit, draft,
writing, resolution, notice, consent, certificate, affidavit, letter, cablegram,
telegram, telecopy, telex or teletype message, statement, order or other
document believed by it to be genuine and correct and to have been signed, sent
or made by the proper Person or Persons and upon advice and statements of legal
counsel, independent accountants and other experts selected by the Agent.  The
Agent shall be fully justified in failing or refusing to take any action under
this Agreement unless it shall first have received such advice or concurrence of
the Majority Banks as it
<PAGE>

                                      -42-

reasonably deems appropriate or it shall first be indemnified to its reasonable
satisfaction by the Banks against any and all liability and expense which may be
incurred by it by reason of taking or continuing to take any such action. The
Agent shall in all cases be fully protected in acting, or in refraining from
acting, under this Agreement in accordance with a request of the Majority Banks,
and such request and any action taken or failure to act pursuant thereto shall
be binding upon the Banks and all future holders of the Revolving Credit Loans
or of a Letter of Credit Participation.

     5.6.  Letter of Credit Fee.
           --------------------

     The Borrower shall pay to the Agent a fee (in each case, a "Letter of
Credit Fee") in respect of each standby Letter of Credit issued pursuant to this
Credit Agreement, equal to the Applicable Margin at the date of issuance,
extension or renewal of such Letter of Credit multiplied by the face amount of
each such Letter of Credit, plus an issuance fee in respect of each standby
                            ----
Letter of Credit equal to 1/8% on the face amount of each such Letter of Credit
(the "Standby Issuance Fee"), and the Agent shall in turn remit to each Bank its
pro rata portion of such Letter of Credit Fee (but not the Standby Issuance
--------
Fee).  The Letter of Credit Fee for each Letter of Credit shall be payable
quarterly in arrears on the last Business Day of each calendar quarter then
ending.  In addition, the Borrower shall pay to the Agent, for its own account,
the Agent's standard issuance, processing, negotiation, amendment and
administrative fees, determined in accordance with customary fees and charges
for similar facilities.

     6.  CERTAIN GENERAL PROVISIONS.
         --------------------------

     6.1.  Fees Payable to Agent.
           ---------------------

          6.1.1.  Amendment Fee.
                  --------- ---

          The Borrower shall pay to the Agent for the account of the Banks, on
     the Effective Date, an amendment fee in the amount of 0.25% of the Exposure
     of each Bank (after giving effect to the reduction in the Total Commitment
     contemplated by this Credit Agreement) that approved this Credit Agreement
     on or before May 14, 2001 and 0.10% of each other Bank's Exposure.

          6.1.2.  Agent's Fee.
                  ------- ---

          The Borrower shall pay to the Agent certain fees as set forth in the
     letter agreement dated as of the Effective Date between the Borrower and
     the Agent.

     6.2.  Payments to Agent.
           -----------------

     All payments of principal, interest, Reimbursement Obligations, commitment
fees, Letter of Credit Fees and any other amounts due hereunder or under any of
the other Loan Documents shall be made to the Agent, for the respective accounts
of the Banks and the Agent, at the Agent's Head Office or at such other location
in the Boston, Massachusetts, area that the Agent may from time to time
designate, in each case in immediately available funds.  All such payments may
be made by debiting an account of the Borrower with the Agent containing
sufficient funds to make such payment; and the Borrower hereby authorizes the
Agent to debit any such account to make payments hereunder when due

     6.3.  Taxes.
           -----

     (a) Any and all payments by the Borrower to each Bank or the Agent under
this Credit Agreement  shall be made free and clear of, and without deduction or
withholding for, any Taxes.  In addition, the Borrower shall pay all Other
Taxes.
<PAGE>

                                      -43-

     (b)  To the fullest extent permitted by applicable law, the Borrower agrees
to indemnify and hold harmless each Bank and the Agent for the full amount of
Taxes and Other Taxes (including any Taxes or Other Taxes imposed by any
jurisdiction on amounts payable under this (S)6.3) paid by such Bank or the
Agent and any liability (including penalties, interest, additions to tax and
expenses) arising therefrom or with respect thereto, whether or not such Taxes
or Other Taxes were correctly or legally asserted.  Payment under this
indemnification shall be made within thirty (30) days after the date the Bank or
the Agent makes written demand therefor in accordance with this (S)6.3.

     (c)  If the Borrower shall be required by law to deduct or withhold any
Taxes or Other Taxes from or in respect of any sum payable hereunder to any Bank
or the Agent, then: (i) the sum payable shall be increased as necessary so that
after making all required deductions and withholdings (including deductions and
withholdings applicable to additional sums payable under this (S)6.3) such Bank
or the Agent, as the case may be, receives an amount equal to the sum it would
have received had no such deductions or withholdings been made; (ii) the
Borrower shall make such deductions and withholdings; and (iii)  the Borrower
shall pay the full amount deducted or withheld to the relevant taxing authority
or other authority in accordance with applicable law.

     (d)  Notwithstanding anything to the contrary contained in this Credit
Agreement, each of the Borrower and the Agent shall be entitled, to the extent
it is required to do so by law, to deduct or withhold income or other similar
taxes imposed by the United States of America from interest, fees or other
amounts payable hereunder for the account of any Bank (without the payment by
the Borrower of increased amounts to such Bank pursuant to clause (a), (b) or
(c) above) other than a Bank (i) which is a domestic corporation (as such term
is defined in Section 7701 of the Code) for federal income tax purposes or (ii)
which has the Prescribed Forms on file with the Borrower and the Agent for the
applicable year, provided that if the Borrower shall so deduct or withhold any
                 --------
such taxes, it shall provide a statement to the Agent and such Bank, setting
forth the amount of such taxes so deducted or withheld, the applicable rate and
any other information or documentation which such Bank or the Agent may
reasonably request for assisting such Bank or the Agent to obtain any allowable
credits or deductions for the taxes so deducted or withheld in the jurisdiction
or jurisdictions in which such Bank is subject to tax.

     (e)  Within thirty (30) days after the date of any payment by the Borrower
of Taxes or Other Taxes, the Borrower shall furnish the Agent the original or a
certified copy of a receipt evidencing payment thereof, or other evidence of
payment satisfactory to the Agent.  Should any Bank or the Agent ever receive
any refund, credit or deduction from any taxing authority to which such Bank or
the Agent would not be entitled but for the payment by the Borrower of Taxes as
required by this (S)6.3 (it being understood that the decision as to whether or
not to claim, and if claimed, as to the amount of any such refund, credit or
deduction shall be made by such Bank or the Agent in its sole discretion), such
Bank or the Agent, as the case may be, thereupon shall repay to the Borrower an
amount with respect to such refund, credit or deduction equal to any net
reduction in taxes actually obtained by such Bank or the Agent, as the case may
be, and determined by such Bank or the Agent, as the case may be, to be
attributable to such refund, credit or deduction.

     (f)  Each Bank shall use its reasonable best efforts (consistent with its
internal policies and legal and regulatory restrictions) to select a
jurisdiction for its lending office or change the jurisdiction of its lending
office, as the case may be, so as to avoid the imposition of any Taxes
<PAGE>

                                      -44-

or Other Taxes or to eliminate any such additional payment by the Borrower which
may thereafter accrue; provided that no such selection or change shall be made
                       --------
if, in the judgment of such Bank, such selection or change would be
disadvantageous to such Bank.

     6.4.  Computations.
           ------------

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

     6.5.  Inability to Determine Eurodollar Rate.
           --------------------------------------

     In the event, prior to the commencement of any Interest Period relating to
any Eurodollar Rate Loan, the Agent shall determine that adequate and reasonable
methods do not exist for ascertaining the Eurodollar Rate that would otherwise
determine the rate of interest to be applicable to any Eurodollar Rate Loan
during any Interest Period, the Agent shall forthwith give notice of such
determination (which shall be conclusive and binding on the Borrower and the
Banks) to the Borrower and the Banks.  In such event (a) any Loan Request,
Advance Request or Conversion Request with respect to Eurodollar Rate Loans
shall be automatically withdrawn and shall be deemed a request for Base Rate
Loans, (b) each Eurodollar Rate Loan will automatically, on the last day of the
then current Interest Period relating thereto, become a Base Rate Loan, and (c)
the obligations of the Banks to make Eurodollar Rate Loans shall be suspended
until the Agent determines that the circumstances giving rise to such suspension
no longer exist, whereupon the Agent shall so notify the Borrower and the Banks.

     6.6.  Illegality.
           ----------

     Notwithstanding any other provisions herein, if any present or future law,
regulation, treaty or directive or change in the interpretation or application
thereof shall make it unlawful for any Bank to make or maintain Eurodollar Rate
Loans, such Bank shall forthwith give notice of such circumstances to the
Borrower and the other Banks and thereupon (a) the commitment of such Bank to
make Eurodollar Rate Loans or convert Loans of another Type to Eurodollar Rate
Loans shall forthwith be suspended and (b) such Bank's Loans then outstanding as
Eurodollar Rate Loans, if any, shall be converted automatically to Base Rate
Loans on the last day of each Interest Period applicable to such Eurodollar Rate
Loans or within such earlier period as may be required by law.  The Borrower
hereby agrees promptly to pay the Agent for the account of such Bank, upon
demand by such Bank, any additional amounts necessary to compensate such Bank
for any costs incurred by such Bank in making any conversion in accordance with
this (S)6.6, including any interest or fees payable by such Bank to lenders of
funds obtained by it in order to make or maintain its Eurodollar Loans
hereunder.

     6.7.  Additional Costs, etc.
           ---------------------

     If any present or future applicable law, which expression, as used herein,
includes statutes, rules and regulations thereunder and interpretations thereof
by any competent court or by any governmental or other regulatory body or
official charged with the administration or the interpretation thereof and
requests, directives, instructions and notices
<PAGE>

                                      -45-

at any time or from time to time hereafter made upon or otherwise issued to any
Bank or the Agent by any central bank or other fiscal, monetary or other
authority (whether or not having the force of law), shall:

          (a)    impose or increase or render applicable (other than to the
     extent specifically provided for in (S)6.8 or elsewhere in this Credit
     Agreement) any special deposit, reserve, assessment, liquidity, capital
     adequacy or other similar requirements (whether or not having the force of
     law) against assets held by, or deposits in or for the account of, or loans
     by, or letters of credit issued by, or commitments of an office of any
     Bank, or

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

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

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

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

     then, and in each such case, the Borrower will, upon demand made by such
Bank or (as the case may be) the Agent at any time and from time to time and as
often as the occasion therefor may arise, pay to such Bank or the Agent such
additional amounts as will be sufficient to compensate such Bank or the Agent
for such additional cost, reduction, payment or foregone interest or
Reimbursement Obligation or other sum; provided, however, the Borrower shall not
                                       --------  -------
be liable for any increased amounts incurred or accrued more than ninety (90)
days prior to the giving by such Bank or (as the case may be) the Agent to the
Borrower of the demand for such increased amounts.

     6.8.  Capital Adequacy.
           ----------------

     If any Bank or the Agent determines after the date hereof that (a) the
adoption of or change in any law, governmental rule, regulation, policy,
guideline or directive (whether or not having the force of law) regarding
capital requirements for banks or bank holding companies or any change in the
interpretation or application thereof by a court or governmental authority with
appropriate jurisdiction, or (b) compliance by such Bank or the Agent or any
corporation controlling such Bank or the Agent with any law, governmental rule,
regulation, policy, guideline or directive (whether or not having the force of
law) of any such entity regarding capital adequacy, has the effect of reducing
the return on such Bank's or the Agent's commitment with respect to any Loans to
a level below that which such Bank or the Agent could have achieved but for such
adoption, change or compliance (taking into
<PAGE>

                                      -46-

consideration such Bank's or the Agent's then existing policies with respect to
capital adequacy and assuming full utilization of such entity's capital) by any
amount deemed by such Bank or (as the case may be) the Agent to be material,
then such Bank or the Agent may notify the Borrower of such fact. To the extent
that the amount of such reduction in the return on capital is not reflected in
the Base Rate, the Borrower agrees to pay such Bank or (as the case may be) the
Agent for the amount of such reduction in the return on capital as and when such
reduction is determined upon presentation by such Bank or (as the case may be)
the Agent of a certificate in accordance with (S)6.9 hereof. Each Bank shall
allocate such cost increases among its customers in good faith and on an
equitable basis. The Borrower shall not be liable for any amounts pursuant to
this (S)6.8 incurred or accruing more than ninety (90) days prior to the
presentation of such certificate.

     6.9.  Certificate.
           -----------

     A certificate setting forth any additional amounts payable pursuant to
(S)(S)6.7 or 6.8 and a brief explanation of such amounts which are due,
submitted by any Bank or the Agent to the Borrower, shall be conclusive, absent
manifest error, that such amounts are due and owing.

     6.10.  Indemnity.
            ---------

     The Borrower agrees to indemnify each Bank and to hold each Bank harmless
from and against any loss, cost or expense (including with respect to the
Applicable Margin and fees owing to the Agent or any Bank) that such Bank may
sustain or incur as a consequence of (a) default by the Borrower in payment of
the principal amount of or any interest on any Eurodollar Rate Loans as and when
due and payable, including any such loss or expense arising from interest or
fees payable by such Bank to lenders of funds obtained by it in order to
maintain its Eurodollar Rate Loans, (b) default by the Borrower in making a
borrowing or conversion after the Borrower has given (or is deemed to have
given) a Loan Request, notice (in the case of all or any portion of Term Loan A
pursuant to (S)4.1.4(b) or Term Loan B pursuant to (S)4.2.4(b) or a Conversion
Request relating thereto in accordance with (S)2.6, (S)2.7, (S)4.1.4(b) or
(S)4.2.4(b)), or (c) the making of any payment of a Eurodollar Rate Loan or the
making of any conversion of any such Loan to a Base Rate Loan on a day that is
not the last day of the applicable Interest Period with respect thereto,
including interest or fees payable by such Bank to lenders of funds obtained by
it in order to maintain any such Loans.

     6.11.  Interest After Default.
            ----------------------

          6.11.1.  Overdue Amounts.
                   ---------------

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

          6.11.2.  Amounts Not Overdue.
                   -------------------

          During the continuance of a Default or an Event of Default, the
     principal amount of the Loans not overdue shall, until such Default or
     Event of Default has been cured or remedied or such Default or event of
     Default has been waived by the Majority Banks pursuant to (S)28, bear
     interest at a rate per annum equal to the two percent (2%) above the rate
     of interest otherwise applicable to such Loans pursuant to (S)2.5,
     (S)4.1.4, and (S)4.2.4.
<PAGE>

                                      -47-

     6.12.  Interest Limitation.
            --------------------

     It is the intention of the parties hereto that each Bank shall conform
strictly to usury laws applicable to it.  Accordingly, if the transactions
contemplated hereby would be usurious as to any Bank under laws applicable to it
(including the laws of the United States of America or any other jurisdictions
whose laws may be mandatorily applicable to such Bank), then, in that event,
notwithstanding anything to the contrary in the Loan Documents, the Credit
Agreement or any other agreements entered into in connection with or as security
for the Obligations, it is agreed as follows:  (a) the aggregate of all
consideration which constitutes interest under laws applicable to any Bank that
is contracted for, taken, reserved, charged or received by such Bank under the
Loan Documents, the Credit Agreement or any other agreements entered into in
connection with or as security for the Obligations or otherwise in connection
with the Obligations shall under no circumstances exceed the maximum amount
allowed by such applicable law, and any excess shall be cancelled automatically
and if theretofore paid shall be credited by such Bank on the principal amount
of the Indebtedness (or, to the extent that the principal amount of the
Indebtedness shall have been or would thereby be paid in full, refunded by such
Bank to the Borrower); and (b) in the event that the maturity of the Loans is
accelerated, or in the event of any required or permitted prepayment, then such
consideration that constitutes interest under law applicable to any Bank may
never include more than the maximum amount allowed by such applicable law, and
excess interest, if any, provided for in this Credit Agreement or otherwise
shall be cancelled automatically by such Bank as of the date of such
acceleration or prepayment and, if therefore paid, shall be credited by such
Bank on the principal amount of the Indebtedness (or, to the extent that the
principal amount of the Indebtedness shall have been or would thereby be paid in
full, refunded by such Bank to the Borrower).  All sums paid or agreed to be
paid to any Bank for the use, forbearance or detention of sums due hereunder
shall, to the extent permitted by laws applicable to such Bank, be amortized,
prorated, allocated and spread through the term of the Loans until payment in
full so that the rate or amount of interest on account of any Loans does not
exceed the maximum amount allowed by such applicable law.  If at any time and
from time to time (a) the amount of interest payable to any Bank on any date
shall be computed at the highest lawful rate applicable to such Bank pursuant to
this paragraph and (b) in respect of any subsequent interest computation period
the amount of interest otherwise payable to such Bank would be less than the
amount of interest payable to such Bank computed at the highest lawful rate
applicable to such Bank, then the amount of interest payable to such Bank in
respect of such subsequent interest computation period shall continue to be
computed at the highest lawful rate applicable to such Bank until the total
amount of interest payable to such Bank shall equal the total amount of interest
which would have been payable to such Bank if the total amount of interest had
been computed without giving effect to this paragraph.

     To the extent that Article 5069-1.04 of the Texas Revised Civil Statutes is
relevant to any Bank for the purpose of determining the highest lawful rate,
each such Bank hereby elects to determine the applicable rate ceiling under such
Article by the indicated (weekly) rate ceiling from time to time in effect.

     6.13.  Replacement of Bank.
            -------------------

     In the event that any Bank makes a demand for payment pursuant to
(S)(S)6.3, 6.7 or 6.8, or terminates the Commitment of the Bank to make, or
convert Loans of another Type to, Eurodollar Rate Loans pursuant to (S)6.6, the
Borrower shall have the right, if no Default or Event of Default then exists, to
replace such Bank in accordance with this (S)6.13.  If the Borrower determines
to replace such Bank, the Borrower shall have the right to replace such Bank
with an entity that is an Eligible Assignee (a "Replacement Bank"); provided
                                                ----------- ----
<PAGE>

                                      -48-

that such Replacement Bank, (a) shall be reasonably acceptable to the Agent, (b)
shall unconditionally offer in writing (with a copy to the Agent) to purchase
all of such Bank's rights under the Loan Documents and interest in the Loans
owing to such Bank and the Reimbursement Obligations owing to such Bank, in each
case without recourse, at the principal amount of such Obligations plus interest
and fees accrued thereon to the date of such purchase on a date therein
specified, and (c) shall execute and deliver to the Agent an Assignment and
Acceptance in accordance with (S)21 hereof.  Upon satisfaction of the
requirements set forth in the second sentence of this (S)6.13, acceptance of
such offer to purchase by the Bank to be replaced, payment to such Bank of the
purchase price in immediately available funds, and the payment by the Borrower
of all requested costs accruing to the date of purchase which the Borrower is
obligated to pay under (S)6.10 and all other amounts owed by the Borrower to
such Bank (other than the principal of and interest on the Obligations of such
Bank purchased by the Replacement Bank), and execution of the Assignment and
Acceptance by all parties thereto in accordance with (S)21 hereof, the
Replacement Bank shall constitute a "Bank" hereunder with a Commitment as so
specified and the Bank being so replaced shall no longer constitute a "Bank"
hereunder and shall thereupon be released from any and all liabilities in
respect of the Credit Agreement and the other Loan Documents.  If, however, (i)
a Bank accepts such an offer and such proposed Replacement Bank fails to
purchase such rights and interests on such specified date in accordance with the
terms of such offer and to execute an Assignment and Acceptance, the Borrower
shall continue to be obligated to pay the increased costs or additional amounts
due to such Bank pursuant to (S)(S)6.3, 6.7 or 6.8 (if a demand for repayment of
increased costs or additional amounts pursuant to any of such Sections is the
basis for the proposed replacement), as the case may be, or (ii) the Bank
proposed to be replaced fails to accept such purchase offer, the Borrower (if
the basis for the proposed replacement is a demand for payment of increased
costs or additional amounts pursuant to (S)(S)6.3, 6.7 or 6.8) shall not be
obligated to pay to such Bank such increased costs or additional amounts
incurred or accrued from and after the date of such purchase offer.

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

     7.1.  Security of Borrower.
           --------------------

perfected first priority security interest in or lien on the Collateral (subject

the terms of the Security Documents to which the Borrower is a party, and (b) a
pledge by the Borrower of (i) one hundred percent (100%) of the capital stock of
each of its Domestic Subsidiaries, and (ii) sixty-six percent (66%) of the
capital stock of each of its Foreign Subsidiaries, pursuant to the terms of the
Stock Pledge Agreement, provided, that the Borrower will not be required to

pledge the capital stock of any Subsidiary which is an Immaterial Subsidiary.

     7.2.  Guaranties and Security of Domestic Subsidiaries.
           ------------------------------------------------

     The Obligations shall also continue to be guaranteed pursuant to the terms
of the Guaranty by each of the Domestic Subsidiaries of the Borrower (unless
such Domestic Subsidiary is an Immaterial Subsidiary).  The obligations of the
Domestic Subsidiaries under the Guaranty shall in turn continue to be equally
and ratably secured by a perfected first priority security interest in or lien
on the Collateral (subject only to Permitted Liens entitled to priority under
applicable law) pursuant to the terms of the Security Documents to which such
Domestic Subsidiary is a party.

     7.3.  Guaranties of Holdings and Petro, Inc.
           -------------------------------------

The Obligations of Holdings under the Holdings Guaranty shall in turn continue
to be solely secured by a perfected first priority security interest in all of
the partnership interests of the Borrower owned by Holdings pursuant to the
Partnership Pledge Agreement to which it is a party. The Obligations of Petro,
Inc. under the General Partner Guaranty shall in turn continue to be solely
secured by a perfected first priority security interest in all of the

     particular capital requirements of the business conducted by Holdings and
     its Subsidiaries and the projected capital requirements and capital
     availability therefor) and the ability to pay their debts from time to time

proceedings or investigations of any kind pending or, to its knowledge,
threatened against the Borrower or any of its Subsidiaries before any court,
tribunal or administrative agency or board as to which there is any reasonable
possibility of an adverse determination which would not reasonably be expected
to have, either in any case or in the aggregate, a material adverse effect on
the business, assets or financial condition of the Borrower and its
Subsidiaries, considered as a whole, or materially impair the right of the
Borrower and its Subsidiaries, considered as a whole, to carry on business
substantially as now conducted by them, or result in any substantial liability
not adequately covered by insurance, or for which adequate reserves are not
maintained on the consolidated balance sheet of the Borrower and its
Subsidiaries, or which question the validity of this Credit Agreement or any of
the other Loan Documents, or any action taken or to be taken pursuant hereto or
thereto.

     8.8.  No Materially Adverse Contracts, etc.
           ------------------------------------

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

     8.10.  Tax Status.
            ----------

     The Borrower and its Subsidiaries (a) have made or filed all federal and
state income and all other material tax returns, reports and declarations
required by any jurisdiction to which any of them is subject, (b) have paid all
taxes and other governmental assessments and charges shown or determined to be
due on such returns, reports and declarations, except those being contested in
good faith and by appropriate proceedings and (c) have set aside on their books
in accordance with generally accepted accounting principles provisions
reasonably adequate for the payment of all taxes for periods subsequent to the
periods to which such returns, reports or declarations apply.  There are no

any jurisdiction (except for amounts contested in good faith after the Effective

1935; nor is it an "investment company", or an "affiliated company" or a
"principal underwriter" of an "investment company", as such terms are defined in

Subsidiaries has engaged in any transaction with any "affiliated company" or
"principal underwriter" of an "investment company" in violation of the
Investment Company Act of 1940.

     8.13.  Absence of Financing Statements, etc.

     Except with respect to Permitted Liens, there is no financing statement,
security agreement, chattel mortgage, real estate mortgage or other document

public office and currently in effect, that purports to cover, affect or give

material assets or property of the Borrower or any of its Subsidiaries or any
rights relating thereto.

     8.14.  Perfection of Security Interest.
            -------------------------------

     All filings, assignments, pledges and deposits of documents or instruments
have been made and all other actions have been taken that are necessary or

interest in the Collateral  (other than filings to be made by the Agent of
financing statements or Mortgages or amendments thereto delivered by the
Borrower and its Subsidiaries on the Effective Date or thereafter as may be
required by the Agent).  The Collateral and the Agent's rights with respect to
the Collateral are not subject to any setoff, claims, withholdings or other
defenses.  The Borrower or a Subsidiary of the Borrower party to one of the

third parties, none of the officers, directors, or employees of the Borrower or
any of its Subsidiaries is presently a party to any transaction with the
Borrower or any of its Subsidiaries (other than for services as employees,
officers and directors), including any contract, agreement or other arrangement
providing for the furnishing of services to or by, providing for rental of real
or personal property to or from, or otherwise requiring payments to or from any
officer, director or such employee or, to the knowledge of the Borrower, any
corporation, partnership, trust or other entity in which any officer, director,
or any such employee has a substantial interest or is an officer, director,
trustee or partner, except as disclosed on Schedule 8.15 hereto and except for
                                           -------- ----
renewals and extensions of the existing agreements described on Schedule 8.15 so
                                                                -------- ----
long as such renewals and extensions are on substantially the same terms as the
agreement being renewed or extended.

     8.16.  Employee Benefit Plans.
            ----------------------

          8.16.1.  In General.
                   ----------

          Except as set forth on Schedule 8.16 hereto, each Employee Benefit
                                 -------------
     Plan has been maintained and operated in compliance in all material
     respects with the provisions of ERISA and, to the extent applicable, the
     Code, including but not
<PAGE>

                                      -54-

     limited to the provisions thereunder respecting prohibited transactions.
     The Borrower has heretofore delivered or made available to the Agent the
     most recently completed annual report, Form 5500, with all required
     attachments, and actuarial statement required to be submitted under
     (S)103(d) of ERISA, with respect to each Guaranteed Pension Plan, if any.

          8.16.2.  Terminability of Welfare Plans.
                   ------------------------------

          Each Employee Benefit Plan which is an employee welfare benefit plan
     within the meaning of (S)3(1) or (S)3(2)(B) of ERISA may be terminated by
     the Borrower or an ERISA Affiliate, as appropriate, at any time (or at any
     time subsequent to the expiration of any applicable bargaining agreement)
     in the discretion of the Borrower or such ERISA Affiliate, without material
     liability to any Person.

          8.16.3.  Guaranteed Pension Plans.
                   ------------------------

          Each contribution required to be made to a Guaranteed Pension Plan,
     whether required to be made to avoid the incurrence of an accumulated
     funding deficiency, the notice or lien provisions of (S)302(f) of ERISA, or
     otherwise, has been timely made.  No waiver of an accumulated funding
     deficiency or extension of amortization periods has been received with
     respect to any Guaranteed Pension Plan.  No liability to the PBGC (other
     than required insurance premiums, all of which have been paid) has been
     incurred by the Borrower or any ERISA Affiliate with respect to any
     Guaranteed Pension Plan and there has not been any ERISA Reportable Event,
     or any other event or condition which presents a material risk of
     termination of any Guaranteed Pension Plan by the PBGC. Based on the latest
     valuation of each Guaranteed Pension Plan (which in each case occurred
     within twelve months prior to the date of this representation), and on the
     actuarial methods and assumptions employed for that valuation, the
     aggregate benefit liabilities of all such Guaranteed Pension Plans within
     the meaning of (S)4001 of ERISA did not exceed the aggregate value of the
     assets of all such Guaranteed Pension Plans by more than $1,000,000,
     disregarding for this purpose the benefit liabilities and assets of any
     Guaranteed Pension Plan with assets in excess of benefit liabilities.

          8.16.4.  Multiemployer Plans.
                   -------------------

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

     8.17.  Regulations U and X.
            -------------------

     The proceeds of the Revolving Credit Loans and the Term Loans shall be used
solely to convert the Obligations under the Original Credit Agreement to
Obligations hereunder, and thereafter for working capital and partnership and
general corporate purposes and Capital Expenditures (including making

Expenditures as permitted hereunder) (subject to the limitations set forth in
(S)(S)9.12 and 11.7 hereof).  The Borrower will obtain Letters of Credit solely
for partnership and general corporate purposes.  No portion of any Loan is to be
used, and no portion of any Letter of Credit is to be obtained, for the purpose
of purchasing or carrying any

present condition and usage of the Real Estate and the operations conducted

     investigation, removal or other response action pursuant to any
     Environmental Law; or (iii) that it is or shall be a named party to any

     proceeding (in each case, contingent or otherwise) arising out of any third
     party's incurrence of costs, expenses, losses or damages of any kind
     whatsoever in connection with the release of Hazardous Substances which
     claim, cause of action or proceeding could have any of the effects
     described in (S)8.7;

     ownership, and to the best of the Borrower's knowledge with respect to all

     Substances on,
<PAGE>

                                      -56-

     upon, into or from the properties of the Borrower or its Subsidiaries,
     which releases would have a material adverse effect on the value of any of
     the Real Estate or adjacent properties or the environment; (iv) to the best
     of the Borrower's knowledge, there have been no releases on, upon, from or
     into any real property in the vicinity of any of the Real Estate which,

     applicable Environmental Laws; and

          (d)  None of the Borrower and its Subsidiaries, any Mortgaged Property

     a substitute or replacement Construction Contract with a new Contractor, in
     which event such new Construction Contract shall be assigned to the Agent
     and a copy of such new

material adverse effect on the Borrower and its Subsidiaries considered as a
whole; provided that this sentence shall not prohibit any transactions permitted
       --------
by (S)10.4 and (S)10.5.  The Borrower (a) will cause all of its properties and

judgment of such Person, desirable in the conduct of its or their business and
that does not, with other such discontinuances, in the aggregate materially

hereto and the general practices of businesses engaged in similar activities in
similar geographic areas and in amounts, containing such terms, in such forms

terms of the Security Agreements.  The Borrower will, and will cause each of its
Subsidiaries to, maintain insurance on the Mortgaged Properties in accordance

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

     $20,000 in the aggregate in any fiscal year.

          9.9.3.  Appraisals.
                  ----------

           Periodically, upon the request of the Agent, the Borrower will obtain
     and deliver to the Agent appraisal reports in form and substance and from
     appraisers satisfactory to the Agent (or will pay the costs and expenses of
     any such appraisals obtained by the Agent), stating the then current fair
     market, orderly liquidation and forced liquidation values of all or any
     portion of the equipment or real estate owned by the Borrower or any of its

     Property prepared by a hydrogeologist, an independent engineer or other
     qualified consultant or expert approved by the Agent to evaluate or confirm
     (a) whether any Hazardous Substances are present in the soil or water at
     such Mortgaged Property and (b) whether the use and operation of such
     Mortgaged Property complies with all Environmental Laws provided, that, at
                                                             --------

     Property including any and all storage areas, storage tanks, drains, dry
     wells and leaching areas, and the taking of soil samples, surface water
     samples and ground water samples, as well as such other investigations or

documents and by-laws, (c) all material agreements and instruments by which it
or any of its properties may be bound except as would not reasonably be expected
to have a material adverse effect on the business, assets or financial condition
of the Borrower and its Subsidiaries considered as a whole, and (d) all
applicable decrees, orders, and judgments. If any authorization, consent,
approval, permit or license from any officer, agency or instrumentality of any
government shall become necessary or required in order that the Borrower or any
of its Subsidiaries may fulfill any of its obligations hereunder or under any of
the other Loan Documents to which such Person is a party, the Borrower will, or

Letters of Credit solely for general corporate or partnership purposes.

hereto regarding "Use of Proceeds"), provided, however, as to any leasehold
                                     --------  -------
interest it shall not be a  Default or Event of Default hereunder if the
Borrower, after using its best efforts to obtain any necessary consents, is
unable to execute and deliver such leasehold mortgage or deed of trust due to a
failure to obtain any third-party consents needed to grant such mortgage or deed
of trust.  The Borrower further agrees that, following the taking of such
actions with respect to such Real Estate, the Agent shall have for the benefit
of the Banks and the Agent a valid and enforceable first priority mortgage or
deed of trust over and security interest in such real estate and related
personal property, free and clear of all liens and encumbrances except for
Permitted Liens.

     9.14.  Cash Management.

with respect to a Project which will increase the Project's Construction Budget
(as the Construction Budget is revised from time to time and approved by the
Agent) and cause the aggregate Construction Budget to be increased by more than
fifteen percent (15%), the Borrower shall promptly notify the Agent in writing
and promptly submit to the Agent for its approval a revised Construction Budget.
No further Revolving Credit Loans for such Project need be made by the Agent
unless and until the revised Construction Budget so submitted by the Borrower to
the Agent is approved by the Agent, and the Agent reserves the right to approve
or disapprove of any revised Construction Budget in its reasonable discretion,
such approval or disapproval to be provided by the Agent in a timely manner.

     9.17.  Contingency Reserve.
            -------------------

     The Borrower covenants and agrees that the amount allocated as Contingency
Reserves in each Construction Budget shall not exceed ten percent (10%) without

     9.18.  Deposit of Funds Advanced.
            -------------------------

     The Borrower may, but shall not be obligated to, open and maintain an

Borrower, for (a) any expenses incurred by the Agent or any Bank (including,
without limiting the generality of the foregoing, Construction Inspector fees
and reasonable attorneys' fees), or (b) any other sums due to the Agent or any
of the Banks under this Credit Agreement or any of the other Loan Documents, all
to the extent that the same are not paid by the respective due dates thereof.

Default, or upon the request of the Borrower, as the case may be, at its option
the Agent may, upon prior written notice to the Borrower, make any or all
advances for construction expenses directly to the Contractor for deposit in an
appropriately designated special bank account, and the execution of this Credit
Agreement by the Borrower shall, and hereby does, constitute an irrevocable
authorization so to advance the proceeds of any Revolving Credit Loan.  No
further authorization from the Borrower shall be necessary to warrant such
direct advances to the Contractor and all such advances shall satisfy pro tanto
                                                                      --- -----

     construction of the Improvements to date is in accordance with the Plans
     and Specifications and to approve the Borrower's then current Loan Request,
     as the case may be, as being consistent with the Construction Budget and
     the Borrower's Obligations under this Credit Agreement.

     The fees of the Construction Inspector shall be paid by the Borrower

thereof shall be reimbursed to the Agent forthwith upon request therefor, but
neither the Agent nor the Construction Inspector shall have any liability to the
Borrower on account of (i) the services performed by the Construction Inspector,
(ii) any neglect or failure on the part of the Construction Inspector to

     have the priority contemplated by the Security Documents, in each case

     prior written agreement, consent or approval of the Agent (other than due
     to the negligence of the Agent in failing to make any filings required to
     be made by the Agent), or any action at law, suit or in equity or other
     legal proceeding to cancel, revoke or rescind any of the Loan Documents
     shall be commenced by or on behalf of the Borrower or any of its
     Subsidiaries party thereto or any of their respective stockholders, or any
     court or any other governmental or regulatory authority or agency of
     competent jurisdiction shall make a determination that, or issue a
     judgment, order, decree or ruling to the effect that, any one or more of

     the terms thereof;

          (o)  with respect to any Guaranteed Pension Plan, an ERISA Reportable
     Event shall have occurred and the Majority Banks shall have determined in
     their reasonable discretion that such event would reasonably be expected to
     result in liability of the Borrower or any of its Subsidiaries to the PBGC
     or such Guaranteed Pension Plan in an aggregate amount exceeding $1,000,000
     and such event in the circumstances occurring would reasonably be expected
     to constitute grounds for the termination of such Guaranteed Pension Plan
     by the PBGC or for the appointment by the appropriate United States
     District Court of a trustee to administer such Guaranteed Pension Plan; or

     Subsidiaries, considered as a whole;

          (q)  there shall occur any material damage to, or loss, theft or
     destruction of, any Collateral, whether or not insured, or any strike,
     lockout, labor dispute, embargo, condemnation, act of God or public enemy,

     consecutive days, the cessation or substantial curtailment of revenue
     producing activities at any facility of the Borrower or any of its
     Subsidiaries if such event or circumstance is not covered by business
     interruption insurance and would reasonably be expected to have a material
     adverse effect on the business, assets or financial condition of the
     Borrower and its Subsidiaries, considered as a whole;

          (r)  there shall occur the loss, suspension or revocation of, or
     failure to renew, any license or permit now held or hereafter acquired by
     the Borrower or any of its Subsidiaries if such loss, suspension,
     revocation or failure to renew would reasonably be expected to have a
     material adverse effect on the business, assets or financial condition of
     the Borrower and its Subsidiaries, considered as a whole; or
<PAGE>

                                      -90-

          (s)  the Borrower or any of its Subsidiaries shall be indicted for a
     state or federal crime, or criminal action shall otherwise have been
     brought against such Person, a punishment for which in any such case could
     include the forfeiture of any assets of such Person having a fair market
     value in excess of $1,000,000;

     then, if such event is an Event of Default, and so long as the same may be
continuing, the Agent may, and upon the request of the Majority Banks shall, by
notice in writing to the Borrower declare all amounts owing with respect to this
Credit Agreement and the other Loan Documents and all Reimbursement Obligations
to be, and they shall thereupon forthwith become, immediately due and payable
without presentment, demand, notice of intention to accelerate maturity
(including, without limitation, the notice of intent to accelerate and the
notice of such acceleration), protest or other notice of any kind all of which
are hereby expressly waived by the Borrower; provided that in the event of any
                                             --------
Event of Default specified in (S)(S)14.1(j) (other than solely with respect to
an Immaterial Subsidiary), 14.1(k) (other than solely with respect to an
Immaterial Subsidiary) or (S)14.1(m) (but only as (S)14.1(m) pertains to the
acceleration of the Senior Notes or the Discount Notes), all such amounts shall
become immediately due and payable automatically and without any requirement of
notice from the Agent or any Bank.

     14.2.  Termination of Commitments.

     If any one or more of the Events of Default specified in (S)14.1(j) (other
than solely with respect to an Immaterial Subsidiary), (S)14.1(k) (other than
solely with respect to an Immaterial Subsidiary) or (S)14.1(m) (but only as
(S)14.1(m) pertains to the acceleration of the Senior Notes or the Discount
Notes) shall occur, any unused portion of the Total Commitment hereunder shall
forthwith terminate and each of the Banks shall be relieved of all further
obligations to make Loans to the Borrower and the Agent shall be relieved of all
further obligations to issue, extend or renew Letters of Credit.  If any other
Event of Default shall have occurred and be continuing, the Agent may and, upon
the request of the Majority Banks shall, by notice to the Borrower, terminate
the unused portion of the Total Commitment hereunder, and upon such notice being
given such unused portion of the Total Commitment hereunder shall terminate
immediately and each of the Banks shall be relieved of all further obligations
to make Loans and the Agent shall be relieved of all further obligations to
issue, extend or renew Letters of Credit.  No termination of the Total
Commitment hereunder shall relieve Holdings, the Borrower or any of its
Subsidiaries of any of the Obligations (other than as provided in (S)2.3).

     14.3.  Remedies.
            --------

     In case any one or more of the Events of Default shall have occurred and be
continuing, and whether or not the Banks shall have accelerated the maturity of
the Loans pursuant to (S)14.1, each Bank, if owed any amount with respect to the
Loans or the Reimbursement Obligations, may, with the consent of the Majority
Banks but not otherwise, proceed to protect and enforce its rights by suit in
equity, action at law or other appropriate proceeding, whether for the specific
performance of any covenant or agreement contained in this Credit Agreement and
the other Loan Documents or any instrument pursuant to which the Obligations to
such Bank are evidenced, including as permitted by applicable law the obtaining
of the ex parte appointment of a receiver, and, if such amount shall have become
       -- -----
due, by declaration or otherwise, proceed to enforce the payment thereof or any
other legal or equitable right of such Bank.  No remedy herein conferred upon
any Bank or the Agent or the holder of any Loans or purchaser of any Letter of
Credit Participation is intended to be exclusive of any other remedy and each
and every remedy shall be cumulative and shall be in addition to every
<PAGE>

                                      -91-

other remedy given hereunder or now or hereafter existing at law or in equity or
by statute or any other provision of law.

     14.4.  Distribution of Collateral Proceeds.
            -----------------------------------

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

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

          (b)  Second, to all other Obligations in such order or preference as
               ------
     the Majority Banks may determine; provided, however, that distributions in
                                       --------  -------
     respect of such obligations shall be made (i) pari passu among Obligations
                                                   ---- -----
     with respect to the Agent's fee payable pursuant to (S)6.2 and all other
     Obligations and (ii) Obligations owing to the Banks with respect to each
     type of Obligation such as interest, principal, fees and expenses, shall be
     made among the Banks pro rata; and provided, further, that the Agent may in
                          --- ----      --------  -------
     its discretion make proper allowance to take into account any Obligations
     not then due and payable;

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

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

     15.  SETOFF.
          ------

     Regardless of the adequacy of any collateral, during the continuance of any
Event of Default, any deposits or other sums credited by or due from any of the
Banks to the Borrower and any securities or other property of the Borrower in
the possession of such Bank may be applied to or set off by such Bank against
the payment of Obligations and any and all other liabilities, direct, or
indirect, absolute or contingent, due or to become due, now existing or
hereafter arising, of the Borrower to such Bank under the Loan Documents.  Each
of the Banks agrees with each other Bank that (a) if an amount to be set off is
to be applied to Indebtedness of the Borrower to such Bank, such amount shall be
applied ratably to such other Indebtedness owed to such Bank, and (b) if such
Bank shall receive from the Borrower, whether by voluntary payment, exercise of
the right of setoff, counterclaim, cross action, enforcement of the claim
constituting Obligations owed to such Bank by proceedings against the Borrower
at law or in
<PAGE>

                                      -92-

equity or by proof thereof in bankruptcy, reorganization, liquidation,
receivership or similar proceedings, or otherwise, and shall retain and apply to
the payment of the Obligations owed to such Bank any amount in excess of its
ratable portion of the payments received by all of the Banks with respect to
the Obligations owed to all of the Banks, such Bank will make such disposition
and arrangements with the other Banks with respect to such excess, either by
way of distribution, pro tanto assignment of claims, subrogation or otherwise
                     --- -----
as shall result in each Bank receiving in respect of the Obligations owed it,
its proportionate payment as contemplated by this Credit Agreement; provided
                                                                    --------
that if all or any part of such excess payment is thereafter recovered from such
Bank, such disposition and arrangements shall be rescinded and the amount
restored to the extent of such recovery, but without interest.

     16.  THE AGENT.
          ---------

     16.1.  Authorization.
            -------------

          (a)  The Agent is authorized to take such action on behalf of each of
     the Banks and to exercise all such powers as are hereunder and under any of
     the other Loan Documents and any related documents delegated to the Agent,
     together with such powers as are reasonably incident thereto, provided that
                                                                   --------
     no duties or responsibilities not expressly assumed herein or therein shall
     be implied to have been assumed by the Agent.

          (b)  The relationship between the Agent and each of the Banks is that
     of an independent contractor.  The use of the term "Agent" is for
     convenience only and is used to describe, as a form of convention, the
     independent contractual relationship between the Agent and each of the
     Banks.  Nothing contained in this Credit Agreement nor the other Loan
     Documents shall be construed to create an agency, trust or other fiduciary
     relationship between the Agent and any of the Banks.  Neither the Co-Agent
     nor the Documentation Agent shall have any duties or responsibilities under
     this Credit Agreement.

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

     16.2.  Employees and Agents.
            --------------------

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

                                      -93-

any such Persons shall be paid by the Borrower, except in any case where this
Credit Agreement provides that the Borrower is not responsible for costs.

     16.3.  No Liability.
            ------------

     Neither the Agent nor any of its shareholders, directors, officers or
employees nor any other Person assisting them in their duties nor any agent or
employee thereof, shall be liable for any waiver, consent or approval given or
any action taken, or omitted to be taken, in good faith by it or them hereunder
or under any of the other Loan Documents, or in connection herewith or
therewith, or be responsible for the consequences of any oversight or error of
judgment whatsoever, except that the Agent or such other Person, as the case may
be, may be liable for losses due to its willful misconduct or gross negligence.

     16.4.  No Representations.
            ------------------

          16.4.1.  General.
                   -------

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

          16.4.2.  Closing Documentation, etc.
                   --------------------------

          For purposes of determining compliance with the conditions set forth
     in (S)12, each Bank that has executed this Credit Agreement shall be deemed
     to have consented to, approved or accepted, or to be satisfied with, each
     document and matter sent by the Agent or the Arranger to, and received by,
     such Bank for consent, approval, acceptance or satisfaction, or required
     thereunder to be consented to or approved by or acceptable or satisfactory
     to such Bank, unless an officer of the Agent or the Arranger active upon
     the Borrower's account shall have received notice from such Bank prior to
     the Effective Date specifying such Bank's objection thereto and such
     objection shall not have been withdrawn by notice to the Agent or the
     Arranger to such effect on or prior to the Effective Date.

     16.5.  Payments.
            --------

                                      -94-

          16.5.1.  Payments to Agent.
                   -----------------

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

          16.5.2.  Distribution by Agent.
                   ---------------------

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

          16.5.3.  Delinquent Banks.
                   ----------------

          Notwithstanding anything to the contrary contained in this Credit
     Agreement or any of the other Loan Documents, any Bank that fails (a) to
     make available to the Agent its pro rata share of any Loan or to purchase
                                     --- ----
     any Letter of Credit Participation or (b) to comply with the provisions of
     (S)15 with respect to making dispositions and arrangements with the other
     Banks, where such Bank's share of any payment received, whether by setoff
     or otherwise, is in excess of its pro rata share of such payments due and
                                       --- ----
     payable to all of the Banks, in each case as, when and to the full extent
     required by the provisions of this Credit Agreement, shall be deemed
     delinquent (a "Delinquent Bank") and shall be deemed a Delinquent Bank
     until such time as such delinquency is satisfied.  A Delinquent Bank shall
     be deemed to have assigned any and all payments due to it from the
     Borrower, whether on account of outstanding Loans, Unpaid Reimbursement
     Obligations, interest, fees or otherwise, to the remaining nondelinquent
     Banks for application to, and reduction of, their respective pro rata
                                                                  --- ----
     shares of all outstanding Loans and Unpaid Reimbursement Obligations.  The
     Delinquent Bank hereby authorizes the Agent to distribute such payments to
     the nondelinquent Banks in proportion to their respective pro rata shares
                                                               --- ----
     of all outstanding Loans and Unpaid Reimbursement Obligations.  A
     Delinquent Bank shall be deemed to have satisfied in full a delinquency
     when and if, as a result of application of the assigned payments to all
     outstanding Loans and Unpaid Reimbursement Obligations of the nondelinquent
     Banks, the Banks' respective pro rata shares of all outstanding Loans and
                                  --- ----
     Unpaid Reimbursement Obligations have returned to those in effect
     immediately prior to such delinquency and without giving effect to the
     nonpayment causing such delinquency.

     16.6.  Holders.
            -------

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

     16.7.  Indemnity.
            ---------

     The Banks ratably agree hereby to indemnify and hold harmless the Agent and
its affiliates from and against any and all claims, actions and suits (whether
groundless or otherwise), losses, damages, costs, expenses (including any
expenses for which the Agent or such affiliate has not been reimbursed by the
Borrower as required by (S)17), and
<PAGE>

                                      -95-

liabilities of every nature and character arising out of or related to this
Credit Agreement (including without limitation (S)16.5.2) or any of the other
Loan Documents or the transactions contemplated or evidenced hereby or thereby,
or the Agent's actions taken hereunder or thereunder, except to the extent that
any of the same shall be directly caused by the Agent's or such affiliate's
willful misconduct or gross negligence.

     16.8.  Agent as Bank.
            -------------

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

     16.9.  Resignation.
            -----------

     The Agent may resign at any time by giving sixty (60) days prior written
notice thereof to the Banks and the Borrower.  Upon any such resignation, the
Majority Banks shall have the right to appoint a successor Agent.  Unless a
Default or Event of Default shall have occurred and be continuing, such
successor Agent shall be reasonably acceptable to the Borrower.  If no successor
Agent shall have been so appointed by the Majority Banks and shall have accepted
such appointment within thirty (30) days after the retiring Agent's giving of
notice of resignation, then the retiring Agent may, on behalf of the Banks,
appoint a successor Agent, which shall be a financial institution having a
rating of not less than A or its equivalent by Standard & Poor's Corporation.
Upon the acceptance of any appointment as Agent hereunder by a successor Agent,
such successor Agent shall thereupon succeed to and become vested with all the
rights, powers, privileges and duties of the retiring Agent, and the retiring
Agent shall be discharged from its duties and obligations hereunder.  After any
retiring Agent's resignation, the provisions of this Credit Agreement and the
other Loan Documents shall continue in effect for its benefit in respect of any
actions taken or omitted to be taken by it while it was acting as Agent.

     16.10.  Notification of Defaults and Events of Default.
             ----------------------------------------------

     Each Bank hereby agrees that, upon learning of the existence of a Default
or an Event of Default, it shall promptly notify the Agent thereof.  The Agent
hereby agrees that upon receipt of any notice under this (S)16.10 it shall
promptly notify the other Banks of the existence of such Default or Event of
Default.

     16.11.  Duties in the Case of Enforcement.
             ---------------------------------

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

     17.  EXPENSES.

                                      -96-

     The Borrower agrees to indemnify and hold harmless the Arranger, the Agent
and the Banks, and their respective affiliates, officers, directors, agents,
trustees and investment advisors, from and against any and all claims, actions
and suits whether groundless or otherwise, and from and against any and all

resulting from a dispute solely between or among the Banks and any dispute
between the Agent and a Bank in which the Agent has been finally determined by a
non-appealable court of competent jurisdiction to have acted with gross
negligence or willful misconduct. In litigation, or the preparation therefor,
the Banks and the Agent shall be entitled to select their own counsel and, in
addition to the foregoing indemnity, the Borrower agrees to pay promptly the
reasonable fees and expenses of such counsel; provided, however, the Borrower
shall only be required to pay the reasonable fees and expenses of one such
counsel for all the Banks and the Agent. If, and to the extent that the
obligations of the Borrower under this (S)18 are unenforceable for any reason,
the Borrower hereby agrees to make the maximum contribution to the payment in
satisfaction of such obligations which is permissible under applicable law. The
Borrower shall be entitled to notice of any proceeding in respect of which a
claim for indemnity or contribution will be made and shall be entitled to
participate in the defense of any such proceeding. The failure to provide such
notice shall not discharge or reduce any indemnity or contribution claim except
to the extent that the Borrower has been prejudiced thereby. The covenants

other Obligations.

     19.  TREATMENT OF CERTAIN CONFIDENTIAL INFORMATION.
          ---------------------------------------------

     19.1.  Sharing of Information with Section 20 Subsidiary.

     Each of the Banks and the Agent agrees, on behalf of itself and each of its

procedures for handling confidential information of the same nature and in

information supplied to it by the Borrower or any of its Subsidiaries pursuant
to this Credit Agreement that is identified by such Person as being
<PAGE>

                                      -98-

confidential at the time the same is delivered to the Banks or the Agent,
provided that nothing herein shall limit the disclosure of any such information
--------
(a) after such information shall have become public other than through a
violation of this (S)19, (b) to the extent required by statute, rule, regulation
or judicial process, (c) to counsel for any of the Banks or the Agent, (d) to
bank examiners or any other regulatory authority having jurisdiction over any

remedies hereunder or under any other Loan Document, (g) to a Subsidiary or
affiliate of such Bank as provided in (S)19.1 (h) to any assignee or participant
(or prospective assignee or participant) so long as such assignee or participant
agrees to be bound by the provisions of (S)21.6, or (i) to any direct or
indirect contractual counterparty in swap agreements or such contractual
counterparty's professional advisor (so long as such contractual counterparty or
professional advisor to such contractual counterparty agrees to be bound by the
provisions of this (S)19.2; provided, that, should disclosure of any such
                            --------
confidential information be required by virtue of either clause (b) or (d)
hereof, the party making such disclosure shall promptly notify the Borrower as
to allow the Borrower to seek a protective order or to take any other
appropriate action; provided, further, that, neither the Agent nor any Bank
                    --------  -------
shall be required to delay compliance with any directive to disclose any such
information so as to allow the Borrower to effect any such action.

     19.3.  Prior Notification.
            ------------------

     Unless specifically prohibited by applicable law or court order, each of
the Banks and the Agent shall, prior to disclosure thereof, notify the Borrower
in writing of any request for disclosure of any such non-public information by
any governmental agency or representative thereof (other than any such request
in connection with an examination of the financial condition of such Bank by
such governmental agency) or pursuant to legal process.

     19.4.  Other.
            -----

     In no event shall any Bank or the Agent be obligated or required to return
any materials furnished to it or any Section 20 Subsidiary by the Borrower or
any of its Subsidiaries.  The obligations of each Bank under this (S)19 shall
supersede and replace the obligations of such Bank under any confidentiality
letter in respect of this financing signed and delivered by such Bank to the
Borrower prior to the date hereof and shall be binding upon any assignee of, or
purchaser of any participation in, any interest in any of the Loans or
Reimbursement Obligations from any Bank.

     20.  SURVIVAL OF COVENANTS, ETC.
          --------------------------

     All covenants, agreements, representations and warranties made herein, in
any of the other Loan Documents or in any documents or other papers delivered by
or on behalf of the Borrower or any of its Subsidiaries pursuant hereto shall be
deemed to have been relied upon by the Banks and the Agent, notwithstanding any
investigation heretofore or hereafter made by any of them, and shall survive the
making by the Banks of any of the Loans and the issuance, extension or renewal

force and effect so long as any Letter of Credit or any amount due under this
Credit Agreement or any of the other Loan Documents remains outstanding or any
Bank has any obligation to make any Loans or the Agent has any obligation to
issue, extend or renew any Letter of Credit, and for such further time as may be
otherwise expressly specified with respect to such provisions in this Credit
Agreement.  Notwithstanding the foregoing, the covenants contained in (S)(S)9,

<PAGE>

                                      -99-

Reimbursement Obligation or Letter of Credit is outstanding or any Bank has any
obligation to make any Loans or the Agent has any obligation to issue, extend or
renew any Letters of Credit.  All written statements contained in any
certificate or other paper delivered to any Bank or the Agent at any time by or
on behalf of the Borrower or any of its Subsidiaries pursuant hereto or in
connection with the transactions contemplated hereby shall constitute
representations and warranties by the Borrower or such Subsidiary hereunder.
The Agent and the Banks acknowledge and agree that the delivery by the Borrower
of its financial projections and forecasts pursuant to this Credit Agreement
does not constitute a representation or warranty by the Borrower or its
Subsidiaries that the Borrower or such Subsidiary will achieve the results
estimated on such projection or forecast.

participation shall be in an amount of not less than $5,000,000, (b) any such
sale or participation shall not affect the rights and duties of the selling Bank
hereunder to the Borrower or of the Borrower to such Bank or give rise to any
Obligation of the Borrower to such participant, and (c) the only rights granted
to the participant pursuant to such participation arrangements with respect to
waivers, amendments or modifications of the Loan Documents shall be the rights

     21.7.  Assignee or Participant Affiliated with the Borrower.
            ----------------------------------------------------

transferor Bank shall promptly notify the Agent of the sale of such
participation.  A transferor Bank shall have no right to vote as a Bank

consents or waivers or for purposes of agreeing to amendments or modifications

beneficially owned by the Borrower or any Affiliate of the Borrower, and the
determination of the Majority Banks shall for all purposes of this Agreement and
the other Loan Documents be made without regard to the interest of such
transferor Bank in the Loans to the extent of such participation.

     21.8.  Miscellaneous Assignment Provisions.
            -----------------------------------

     Any assigning Bank shall retain its rights to be indemnified pursuant to
(S)18 with respect to any claims or actions arising prior to the date of such
assignment.  If any assignee Bank is not incorporated under the laws of the
United States of America or any state thereof, it shall, as a condition
precedent to the effectiveness of the assignment and prior to the date on which
any interest or fees are payable hereunder or under any of the other Loan
Documents for its account, deliver to the Borrower and the Agent certification
as to its exemption from deduction or withholding of any United States federal
income taxes.  If any Reference Bank transfers all of its interest, rights and
obligations under this Credit Agreement, the Agent shall, in consultation with
the Borrower and with the consent of the Borrower and the Majority Banks,
appoint another Bank to act as a Reference Bank hereunder.  Anything contained
in this (S)21 to the contrary notwithstanding, any Bank may at any time pledge
all or any portion of its interest and rights under this Credit Agreement
(including all or any portion of its Loans) (a) to any of the twelve Federal
Reserve Banks organized under (S)4 of the Federal Reserve Act, 12 U.S.C. (S)341
and (b) any Bank that is a fund that invests in bank loans may at any time
pledge all or any portion of its interests and rights with respect to its Loans
to any trustee for, or any other representative of, holders of obligations owed
or securities issued by such fund as security for such obligations or
securities, provided that any foreclosure or similar action by such trustee or
            --------
other representative shall be subject to the other provisions of this (S)21.  No
such pledge or the enforcement thereof shall release the pledgor Bank from its
obligations hereunder or under any of the other Loan Documents.

     21.9.  Assignment by Borrower.
            ----------------------

     26.  ENTIRE AGREEMENT, ETC.
          ---------------------

     The Loan Documents and any other documents executed in connection herewith

or provision of this Credit Agreement or Loan in any jurisdiction.

incorporator, past, present or future, of the Borrower or any of its
