office at 100 Federal Street, Boston, Massachusetts 02110 (hereinafter sometimes
the "Agent" as Agent for itself and each of the other Lenders who now and/or
hereafter become parties to this Agreement pursuant to the terms of Section 9.11
                                                                    ------------
hereof (the "Lenders"), sometimes in each of its capacities "Fleet" and
sometimes in its capacity as a Lender, "Lender", and such Lenders, hereby agree
as follows:



                                  ARTICLE 1.

                  DEFINITIONS AND ACCOUNTING AND OTHER TERMS

     Section 1.1.  Certain Defined Terms.  As used in this Agreement, the
     ------------  ---------------------
following terms shall have the following meanings (such meanings to be equally
applicable to both the singular and plural forms of the terms defined):


     "Adjusted Libor Rate" means, with respect to any Libor Loan to be made by
      -------------------
the Lenders for the Interest Period applicable to such Libor Loan, the interest
rate per annum determined by the Agent (fixed throughout such Interest Period
((subject to adjustments for the Libor Rate Reserve Percentage)) and rounded
upwards, if necessary, to the next 1/16 of 1%) which is equal to the quotient of
(i) the rate of interest determined by the Agent to be the average of the
interest rates per annum at which Dollar deposits in immediately available funds
are offered to each Reference Lender by first-class banks in the London
interbank market at approximately 11:00 a.m., London time, two Business Days
prior to the Business Day on which such Interest Period begins, in an amount
approximately equal to the principal amount of such Libor Loan, for a period of
time equal to such Interest Period and (ii) a number equal to the number one
minus the Libor Rate Reserve Percentage.  The "Libor Rate Reserve Percentage"
applicable to any Interest Period means the average of the maximum effective
rates (expressed as a decimal) of the statutory reserve requirements (without
duplication, but including, without limitation, basic, supplemental, marginal
and emergency reserves) applicable to each Reference Lender during such Interest
Period under regulations of the Board of Governors of the Federal Reserve System
(or any successor), including without limitation Regulation D or any other
regulation dealing with maximum reserve requirements which are applicable to
each Reference Lender with respect to its "Eurocurrency Liabilities", as that
term may be defined from time to time by the Board of Governors of the Federal
Reserve System (or any successor) or are otherwise imposed by the Board of
Governors of the Federal Reserve System (or any successor) and which in any
other respect relate directly to the funding of loans bearing interest at rates
based on the interest rates at which Dollar deposits in immediately available
funds are offered to banks by first-class banks in the London interbank market.
If any Reference Lender fails to provide its offered quotation to the Agent, the
Adjusted Libor Rate shall be determined on the basis of the offered quotation of
the other Reference Lender.  The Adjusted Libor Rate shall be adjusted
automatically on and as of the effective date of any change in the Libor Rate
Reserve Percentage.

     Section 2.1.  The Loans.
     -----------   ---------


          Section 2.1.0.  The Revolving Credit Loans.  Each of the Lenders
          -------------   --------------------------
severally agrees, subject to the terms and conditions of this Agreement, to make
Advances of Revolving Credit Loans to the Borrower from time to time after
receipt by the Agent from time to time before the Revolving Credit Repayment
Date of, and at the times provided for in, a Request and an Interest Rate
Election from the Borrower in accordance with this Agreement, during the period
commencing on the Closing Date and ending on the Business Day immediately
preceding the Revolving Credit Repayment Date, in an aggregate principal amount
at any one time outstanding not to exceed the lesser of (i) such Lender's Pro
Rata Share of the Revolving Credit Loan Commitment less (ii) in each case, such
Lender's Pro Rata Share of the aggregate outstanding stated amount of any
Letters of Credit and, without duplication, Letter of Credit Agreements and any
unreimbursed amounts drawn thereunder.


     Promptly after receipt of a Request and Interest Rate Election, Agent shall
notify each Lender by telephone, telex or telecopy of the proposed borrowing.
Subject to the immediately preceding paragraph, each Lender agrees that after
its receipt of notification from Agent of

                                       19
<PAGE>

Agent's receipt of a Request and Interest Rate Election, such Lender shall send
its Pro Rata Share (or such portion thereof as may be necessary to provide Agent
with such Pro Rata Share in Dollars and in immediately available funds, without
consideration or use of any contra accounts of any Lender) of the requested Loan
by wire transfer to Agent so that Agent receives such Pro Rata Share in Dollars
and in immediately available funds not later than 12:00 P.M. (Boston,
Massachusetts time) on the first day of the Interest Period for any such
requested Libor Loan and on the Business Day for such Advance set forth in
Borrower's Request for any such requested Prime Rate Loan, and Agent shall
advance funds to the Borrower by depositing such funds in Borrower's account
with the Agent upon Agent's receipt of such Pro Rata Shares in the amount of the
Pro Rata Shares of such Loan in Agent's possession. Unless Agent shall have been
notified by any Lender (which notice may be telephonic if confirmed promptly in
writing) prior to the first day of the Interest Period in respect of any Loan
which such Lender is obligated to make under this Agreement, that such Lender
does not intend to make available to Agent such Lender's Pro Rata Share of such
Loan on such date, Agent may assume that such Lender has made such amount
available to Agent on such date and Agent in its sole discretion may, but shall
not be obligated to, make available to the Borrower a corresponding amount on
such date. If such corresponding amount is not in fact made available to Agent
by such Lender, Agent shall be entitled to recover such corresponding amount
from such Lender promptly upon demand by Agent together with interest thereon,
for each day from such date until the date such amount is paid to Agent, at the
Federal Funds Rate for three (3) Business Days and thereafter at the interest
rate on the Loan in question. If such Lender does not pay such corresponding
amount forthwith upon Agent's demand therefor, Agent shall promptly notify the
Borrower and the Borrower shall promptly pay such corresponding amount to Agent.
Nothing contained in this Section shall be deemed to relieve any Lender from its
obligation to fulfill its obligations hereunder or to prejudice any rights which
the Borrower may have against any Lender as a result of any default by such
Lender hereunder.


     Throughout the term of the Revolving Credit Loans, $2,000,000 of the
Revolving Credit Loan Commitment and principal amount of the Revolving Credit
Loans may, at the Borrower's request and with the Agent's approval which shall
not be unreasonably withheld or delayed, be made available to the Borrower prior
to the Revolving Credit Repayment Date by issuance of Letters of Credit having
an expiration date prior to the earlier to occur of (a) the first anniversary
date of the date of issuance of any such Letter of Credit or (b) three (3)
Business Days prior to the Revolving Credit Repayment Date, reasonably promptly
after submission by the Borrower to the Agent of a Letter of Credit Agreement,
duly completed and executed by the Borrower and otherwise in form and substance
satisfactory to the Agent.  The Borrower shall pay upon demand by the Agent such
fees and costs as the Agent may from time to time establish for issuance,
transfer, amendment and negotiation of each Letter of Credit and shall pay to
the Agent for the Agent's account upon issuance of any Letter of Credit an
annual Letter of Credit fee in an amount equal to the product of (i) the stated
amount of each Letter of Credit multiplied by (ii) the Applicable Margin then in
effect with respect to any Revolving Credit Loan which is a Libor Loan such per
annum fee being pro rated for the term of any Letter of Credit which is other
than a full year in length.  In the event that the Borrower shall fail to
reimburse the Agent under any Letter of Credit or Letter of Credit Agreement,
and any outstanding Indebtedness of the Borrower relating thereto, the Agent
shall promptly notify each Lender of the unreimbursed amount together with
accrued interest thereon, and each Lender agrees to purchase, and it shall be
deemed to have purchased, a participation in such Letter of Credit or Letter of
Credit

                                       20
<PAGE>

Agreement and such Indebtedness in an amount equal to its Pro Rata Share of the
unpaid amount together with unpaid interest thereon. Upon one (1) Business Day's
notice from the Agent, each Lender shall deliver to the Agent an amount equal to
its respective participation in same day funds, at the place and on the date and
by the time notified by the Agent. The obligation of each Lender to deliver to
the Agent an amount equal to its respective participation pursuant to the
foregoing sentence shall be absolute and unconditional and such remittance shall
be made notwithstanding the occurrence or continuation of an Event of Default or
the failure to satisfy any condition set forth in Article III of this Agreement.


     As soon as is practicable following the close of each month after the
Closing Date and in any event within fifteen (15) days thereafter, the Borrower
will submit to the Agent a borrowing base certificate in the form of Exhibit
                                                                     -------
2.1.0 or on such other form as the Agent may from time to time prescribe, which
-----
certificate shall contain information adequate to identify accounts receivable
which the Borrower wishes to include in Eligible Receivables.  During the
continuance of a Default or Event of Default, the Borrower shall also, if the
Lender so requests, accompany such information with assignments of accounts in
form and substance satisfactory to the Lender which assignments shall give the
Lender full power to collect, compromise or otherwise deal with the assigned
accounts as the sole owner thereof.  Concurrently with each of such reports, and
immediately if material in amount, the Borrower shall notify the Lender of each
return or adjustment, rejection, repossession or loss, theft or damage of or to
merchandise represented by Eligible Receivables or any other collateral for any
Indebtedness of the Borrower to the Lender and of any credit, adjustment or
dispute arising in connection with the goods or services represented by Eligible
Receivables.  All payments on Eligible Receivables and all adjustments and
credits with respect thereto, whether unilateral, negotiated or otherwise, shall
be immediately reflected in the Net Outstanding Amount of Eligible Receivables.


     Section 2.2.  Interest and Fees on the Loans.
     -----------   ------------------------------


          Section 2.2.1.  Interest.  Interest shall accrue and be paid currently
          -------------   --------
on the Loans at Effective Prime or the Libor Rate for each of the Loans'
Interest Periods in accordance with the Borrower's Interest Rate Elections for
the Loans subject to and in accordance with the terms and conditions of this
Agreement and the Note(s); provided that if a Default or an Event of Default
exists and is continuing, no Interest Rate Election electing the Libor Rate
shall be effective and any Prime Rate Loan shall bear interest, payable on
demand, at Effective Prime plus, so long as an Event of Default exists and is
continuing, four percent (4.0%) and each Libor Loan shall bear interest, payable
on demand, at the Libor Rate plus four percent (4.0%); all of the foregoing
being applicable until such Default or Event of Default is cured or waived and
an Interest Rate Election electing the Libor Rate for such Loan or portion
thereof which is effective in accordance with this Agreement is submitted to the
Agent.  The Borrower shall pay such interest to the Agent for the pro rata
account of each Lender in arrears on the Loans (including without limitation
Libor Loans) outstanding from time to time after the Closing Date, such payments
to be made monthly on the last Business Day of each calendar month commencing
January 31, 2000 and on the Interest Adjustment Date for Libor Loans.  In the
event no Interest Rate Election has been made by the Borrower with respect to
any Loan or Advance (or an Interest Rate Election shall have expired without an
effective substitute Interest Rate Election), Effective Prime shall be the rate
applicable to such Loan or Advance.  All provisions of each Note and any other
agreements between the Borrower and the Lenders are expressly subject to the
condition

                                       21
<PAGE>

that in no event, whether by reason of acceleration of maturity of the
Indebtedness evidenced by any Note or otherwise, shall the amount paid or agreed
to be paid to the Lenders which is deemed interest under applicable law exceed
the maximum permitted rate of interest under applicable law (the "Maximum
Permitted Rate"), which shall mean the law in effect on the date of this
Agreement, except that if there is a change in such law which results in a
higher Maximum Permitted Rate, then each Note shall be governed by such amended
law from and after its effective date. In the event that fulfillment of any
provision of any Note, or this Agreement or any document, instrument or
agreement providing security for any Note results in the rate of interest
charged under any Note being in excess of the Maximum Permitted Rate, the
obligation to be fulfilled shall automatically be reduced to eliminate such
excess. If, notwithstanding the foregoing, any Lender receives an amount which
under applicable law would cause the interest rate under any Note to exceed the
Maximum Permitted Rate, the portion thereof which would be excessive shall
automatically be deemed a prepayment of and be applied to the unpaid principal
balance of such Note to the extent of then outstanding Prime Rate Loans and not
a payment of interest and to the extent said excessive portion exceeds the
outstanding principal amount of Prime Rate Loans, said excessive portion shall
be repaid to the Borrower.


          Section 2.2.2.  Fees.  On the Closing Date the Borrower shall pay the
          -------------   ----
Facility Fee to the Agent for the accounts of the Lenders and then and
thereafter shall pay certain other fees to the Agent for the Agent's account all
in accordance with the Fee Letter.  In addition, on the last Business Day of
each March, June, September and December commencing March 30, 2000 and
continuing through  the Revolving Credit Repayment Date, the Borrower shall pay
to the Agent for the pro rata account of each Lender, a fee ("Unused Fees") in
an amount equal to the Applicable Margin times the amount, if any, by which the
average actual daily amount of the component of the Revolving Credit Loan
Commitment contained in clause (ii) of the definition of such Commitment for the
quarterly period just ended (or in the case of the first such payment, the
period from the Closing Date to the date such payment is due) exceeds the
average of the actual daily outstanding principal balances of the Revolving
Credit Loans plus the average of the actual daily aggregate outstanding stated
             ----
amounts of any Letters of Credit and, without duplication, Letter of Credit
Agreements, and any unreimbursed amounts thereunder (the "Unused Amount").


          Section 2.2.3.  Increased Costs - Capital.  If, after the date hereof,
          -------------   -------------------------
any Lender shall have reasonably determined that the adoption after the date
hereof of any applicable law, governmental rule, regulation or order regarding
capital adequacy of banks or bank holding companies, or any change therein, or
any change in the interpretation or administration thereof by any governmental
authority, central bank or comparable agency charged with the interpretation or
administration thereof, or compliance by such Lender or such Lender's holding
company with any policy, guideline, directive or request regarding capital
adequacy (whether or not having the force of law and whether or not failure to
comply therewith would be unlawful) of any such authority, central bank or
comparable agency, has or would have the effect of reducing the rate of return
on the capital of such Lender or such Lender's holding company as a consequence
of the obligations hereunder of such Lender to a level below that which such
Lender could have achieved but for such adoption, change or compliance (taking
into consideration the policies of such Lender or such Lender's holding company
with respect to capital adequacy immediately before such adoption, change or
compliance and assuming that the capital of such Lender or such Lender's holding
company was fully utilized prior to such

                                       22
<PAGE>

adoption, change or compliance) by an amount reasonably deemed by such Lender to
be material, then such Lender shall notify the Agent and the Borrower thereof
and the Borrower shall pay to the Agent for the account of such Lender from time
to time as specified by such Lender such additional amounts as shall be
sufficient to compensate such Lender for such reduced return, each such payment
to be made by the Borrower within five (5) Business Days after each demand by
such Lender; provided that the liability of the Borrower to pay such costs shall
only accrue with respect to costs accruing from and after the 90th day prior to
the date of each such demand. A certificate in reasonable detail of one of the
officers of such Lender describing the event giving rise to such reduction and
setting forth the amount to be paid to such Lender hereunder and a computation
of such amount shall accompany any such demand and shall, in the absence of
manifest error, be conclusive. In determining such amount, such Lender shall act
reasonably and will use any reasonable averaging and attribution methods. If the
Borrower shall, as a result of the requirements of this Section 2.2.3 above, be
                                                        -------------
required to pay any Lender the additional costs referred to above and the
Borrower, in its sole discretion, shall deem such additional amounts to be
material, the Borrower shall have the right to substitute another bank
satisfactory to the Agent for such Lender which has certified the additional
costs to the Borrower, and the Agent shall use reasonable efforts at no cost to
the Agent to assist the Borrower to locate such substitute bank. Any such
substitution shall take place in accordance with Section 9.11 and shall
                                                 ------------
otherwise be on terms and conditions reasonably satisfactory to the Agent, and
until such time as such substitution shall be consummated, the Borrower shall
continue to pay such additional costs. Upon any such substitution, the Borrower
shall pay or cause to be paid to the Lender that is being replaced, all
principal, interest (to the date of such substitution) and other amounts owing
hereunder to such Lender and such Lender will be released from liability
hereunder.


     Section 2.3.  Notations.  At the time of (i) the making of each Advance
     -----------   ---------
evidenced by any Note, (ii) each change in the interest rate under any Note
effected as a result of an Interest Rate Election; and (iii) each payment or
prepayment of any Note, each Lender may enter upon its records an appropriate
notation evidencing (a) such Lender's Pro Rata Share of the Loans and (b) the
interest rate and Interest Adjustment Date applicable thereto or (c) such
payment or prepayment (voluntary or involuntary) of principal and (d) in the
case of payments or prepayments (voluntary or involuntary) of principal, the
portion of the applicable Loan which was paid or prepaid.  No failure to make
any such notation shall affect the Borrower's unconditional obligations to repay
the Loans and all interest, fees and other sums due in connection with this
Agreement and/or any Note in full, nor shall any such failure, standing alone,
constitute grounds for disproving a payment of principal by the Borrower.
However, in the absence of manifest error, such notations and each Lender's
records containing such notations shall constitute presumptive evidence of the
facts stated therein, including, without limitation, the outstanding amount of
such Lender's Pro Rata Share of the Loans and all amounts due and owing to such
Lender at any time.  Any such notations and such Lender's records containing
such notations may be introduced in evidence in any judicial or administrative
proceeding relating to this Agreement, the Loans or any Note.

     Section 2.5.1.  Time.  All payments and prepayments of principal,
     -------------   ----
fees, interest and any other amounts owed from time to time under this Agreement
and/or under each Note shall be made to the Agent for the pro rata account of
each Lender at the address referred to in Section 9.6 in Dollars and in
                                          -----------
immediately available funds prior to 12:00 o'clock P.M. on the Business Day that
such payment is due, provided that the Borrower hereby authorizes and instructs
the Agent to charge against the Borrower's accounts with the Agent on each date
on which a payment is due hereunder and/or under any Note and on any subsequent
date if and to the extent any such payment is not made when due an amount up to
the principal, interest and fees due and payable to the Lenders, the Agent or
any Lender hereunder and/or under any Note and such charge shall be deemed
payment hereunder and under the Note(s) in question to the extent that
immediately available funds are then in such accounts.  The Agent shall use
reasonable efforts in accordance with the Agent's customary procedures to give
subsequent notice of any such charge to the Borrower, but the failure to give
such notice shall not affect the validity of any such charge.  To the extent
that immediately available funds are then in such accounts, the failure of the
Agent to charge any such account or the failure of the Agent to charge any such
account prior to 12 o'clock P.M. shall not be basis for an Event of Default
under Section 6.1.1 and any amount due on the Loans on such date shall be deemed
      -------------
paid; provided that the Agent shall have the right to charge any such account on
any subsequent date for such unpaid payment and an Event of Default shall exist
if sufficient immediately available funds are not in such accounts on the date
the Agent so charges such account after the expiration of any applicable cure
period.  In the event of any charge against the Borrower's accounts by the Agent
pursuant to the immediately preceding sentence, the Agent shall use reasonable
efforts to provide notice to the Borrower of such charge in accordance with the
Agent's customary procedures, but the failure to provide such notice shall not
in any way be a basis for any liability of the Agent nor shall such failure
adversely affect the validity and effectiveness of any such action by the Agent.
Any such payment or prepayment which is received by the Agent in Dollars and in
immediately available funds after 12 o'clock P.M. on a Business Day shall be
deemed received for all purposes of this Agreement on the next succeeding
Business Day unless the failure by Agent to receive such funds prior to 12
o'clock P.M. is due to Agent's failure to charge the account of Borrower prior
to 12 o'clock P.M., except that solely for the purpose of determining whether a
Default or Event of Default has occurred under Section 6.1.1, any such payment
                                               -------------
or prepayment, if received by the Agent prior to the close of the Agent's
business  on a Business Day, shall be deemed received on such Business Day.  All
payments of principal, interest, fees and any other amounts which are owing to
any or all of the Lenders or the Agent hereunder and/or under any of the Notes
that are received by the Agent in immediately available Dollars prior to 12:00
o'clock P.M. on any Business Day shall, to the extent owing to the Lenders other
than the Agent, be sent by wire transfer by the Agent to any such other Lenders
(in each case, without deduction for any claim, defense or offset of any type)
before 3:00 o'clock P.M. on the same Business Day.  Each such wire transfer
shall be addressed to each Lender in accordance with the wire instructions set
forth in Exhibit 1.9 hereto.  The amount of each payment wired by the Agent to
         -----------
each such Lender shall be such amount as shall be necessary to provide such
Lender with its Pro Rata Share of such payment (without consideration or use of
any contra accounts of any Lender), or with such other amount as may be owing to
such Lender in accordance with this Agreement (in each case, without deduction
for any claim, defense or offset of any type).  Each such wire transfer shall be
sent by the Agent only after the Agent has received immediately available
Dollars from or on behalf of the Borrower and each such wire transfer shall
provide each Lender

                                       24
<PAGE>

receiving same with immediately available Dollars on receipt by such Lender. Any
such payments of immediately available Dollars received by the Agent after 12:00
o'clock P.M. and before 3:00 o'clock P.M. on any Business Day shall be forwarded
in the same manner by the Agent to such Lender(s) as soon as practicable on said
Business Day, and if any such payments of immediately available Dollars are
received by the Agent after 3:00 o'clock P.M. on a Business Day, the Agent shall
so forward same to such Lender(s) before 10:00 o'clock A.M. on the immediately
succeeding Business Day.


          Section 2.5.2.  Setoff, etc. Borrower and any Subsidiaries hereby
          -------------   -----------
grant to the Agent and each Lender a Lien, security interest and right of setoff
as security for all Obligations to the Agent and such Lender whether now
existing or hereafter arising.  Regardless of the adequacy of any collateral for
any of the Obligations, and subject to the provisions of Article 7 upon the
                                                         ---------
occurrence and during the continuance of any Event of Default, each Lender is
hereby authorized at any time and from time to time, without prior notice to the
Borrower (any such notice being expressly waived by the Borrower), to set off
and apply any and all deposits (general or special, time or demand, provisional
or final) credits, collateral and property at any time in the possession ,
custody, safekeeping or control of such Lender or any entity under the control
of any Lender's holding company or in transit to any of them and any other
Indebtedness at any time owing by such Lender to or for the credit or the
account of the Borrower against any and all of the Obligations of the Borrower
irrespective of whether or not such Lender shall have made any demand under this
Agreement or any Note and although such Obligations may be unmatured.  Each such
Lender agrees to promptly notify the Borrower and the Agent after any such
setoff and application; provided that the failure to give such notice shall not
affect the validity of such setoff and application.  Promptly following any
notice of setoff received by the Agent from a Lender  pursuant to the foregoing,
the Agent shall notify each other Lender thereof.  The rights of each Lender
under this Section 2.5.2 are in addition to all other rights and remedies
           -------------
(including, without limitation, other rights of setoff) which such Lender may
have and are subject to Section 9.12.  ANY AND ALL RIGHTS TO REQUIRE THE AGENT
                        ------------
OR ANY LENDER TO EXERCISE ITS RIGHTS OR REMEDIES WITH RESPECT TO ANY OTHER
COLLATERAL WHICH SECURES THE LOANS, PRIOR TO EXERCISING ITS RIGHT OF SETOFF WITH
RESPECT TO SUCH DEPOSITS, CREDITS OR OTHER PROPERTY OF THE BORROWER OR ANY
GUARANTOR, ARE HEREBY KNOWINGLY, VOLUNTARILY AND IRREVOCABLY WAIVED.

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


          Section 2.5.3.1  The Borrower's obligation to make all payments
          ---------------
provided for in this Agreement and the other Financing Documents shall be
unconditional.  Each such payment shall be made without deduction for any claim,
defense or offset of any type, including without limitation any withholdings and
other deductions on account of income or other taxes (except to  the extent
provided in Section 2.5.3.2) and regardless of whether any claims, defenses or
            ---------------
offsets of any type exist.


          Section 2.5.3.2.  (a)  Any and all payments by the Borrower to or for
          ---------------
the account of any Lender or the Agent hereunder or under any other Financing
Document shall be made free and clear of and without deduction for any and all
present or future taxes, duties, levies, imposts, deductions, charges or
withholdings, and all liabilities with respect thereto,

                                       25
<PAGE>

excluding, in the case of each Lender and the Agent, taxes imposed on its
income, and franchise taxes imposed on it, by the jurisdiction under the laws of
which such Lender (or its applicable lending office) or the Agent (as the case
may be) is organized or any political subdivision thereof, other than to the
extent such income or franchise tax is imposed solely as a result of the
activities of the Agent or a Lender pursuant to or in respect of this Agreement
or any of the other Financing Documents (all such non-excluded taxes, duties,
levies, imposts, deductions, charges, withholdings, and liabilities being
hereinafter referred to as "Taxes"). If the Borrower shall be required by law to
deduct any Taxes from or in respect of any sum payable under this Agreement or
any other Financing Document to any Lender or the Agent,(i) the sum payable
shall be increased as necessary so that after making all required deductions
(including deductions applicable to additional sums payable under this Section
                                                                       -------
2.5.3.2) such Lender or the Agent receives an amount equal to the sum it would
-------
have received had no such deductions been made, (ii) the Borrower shall make
such deductions, (iii) the Borrower shall pay the full amount deducted to the
relevant taxation authority or other authority in accordance with applicable
law, and (iv) the Borrower shall furnish to the Agent, at its address referred
to in Section 9.6 hereof, the original or a certified copy of a receipt
      -----------
evidencing payment thereof.

     (b) In addition, the Borrower agrees to pay any and all present or future
stamp or documentary taxes and any other excise or property taxes or charges or
similar levies which arise from any payment made under this Agreement or any
other Financing Document or from the execution or delivery of, or otherwise with
respect to, this Agreement or any other Loan Document (hereinafter referred to
as "Other Taxes").


     (c) The Borrower agrees to indemnify each Lender and the Agent for the full
amount of Taxes and Other Taxes (including, without limitation, any Taxes or
Other Taxes imposed or asserted by any jurisdiction on amounts payable under
this Section 2.5.3.2) paid by such Lender or the Agent (as the case may be) and
     ---------------
any liability (including penalties, interest, and expenses) arising therefrom or
with respect thereto.


     (d) Each Lender organized under the laws of a jurisdiction outside the
United States, on or prior to the date of its execution and delivery of this
Agreement in the case of each Lender listed on the signature pages hereof and on
or prior to the date on which it becomes a Lender in the case of each other
Lender, and from time to time thereafter if requested in writing by the Borrower
or the Agent (but only so long as such Lender remains lawfully able to do so),
shall provide the Borrower and the Agent with (i) a properly completed Internal
Revenue Service Form 1001 or 4224, as appropriate, or any successor form
prescribed by the Internal Revenue Service, certifying that such Lender is
entitled to benefits under an income tax treaty to which the United States is a
party which reduces the rate of withholding tax on payments of interest or
certifying that the income receivable pursuant to this Agreement is effectively
connected with the conduct of a trade or business in the United States, (ii) a
properly completed Internal Revenue Service Form W-8 or W-9, as appropriate, or
any successor form prescribed by the Internal Revenue Service, certifying that
such Lender is exempt from United States backup withholding, and (iii) any other
form or certificate required by any taxing authority (including any certificate
required by Sections 871(h) and 881(c) of the Internal Revenue Code), certifying
that such Lender is entitled to an exemption from or a reduced rate of tax on
payments pursuant to this Agreement or any of the other Financing Documents.




                                       26
<PAGE>

     (e) For any period with respect to which a Lender has failed to provide the
Borrower and the Agent with the appropriate form pursuant to Section 2.5.3.2(d)
hereof (unless such failure is due to a change in treaty, law, or regulation
occurring subsequent to the date on which a form originally was required to be
provided), such Lender shall not be entitled to indemnification under Section
                                                                      -------
2.5.3.2(a) or 2.5.3.2(b) hereof with respect to Taxes imposed by the United
------------------------
States; provided, however, that should a Lender, which is otherwise exempt from
or subject to a reduced rate of withholding tax, become subject to Taxes because
of its failure to deliver a form required hereunder, the Borrower shall take
such steps as such Lender shall reasonably request and at such Lender's cost to
assist such Lender to recover such Taxes.

     (f) If the Borrower is required to pay additional amounts to or for the
account of any Lender pursuant to this Section 2.5.3.2, then such Lender will
agree to use reasonable efforts to change the jurisdiction of its applicable
lending office so as to eliminate or reduce any such additional payment which
may thereafter accrue if such change, in the judgment of such Lender, is not
otherwise disadvantageous to such Lender.  Alternatively, in the event of such
an additional cost, the Borrower shall have the right to substitute another bank
satisfactory to the Agent, and the Agent and such Lender shall use reasonable
efforts at no cost to the Agent and such Lender to assist the Borrower to locate
and effect the substitution in favor of such substitute bank.  Any such
substitution shall take place in accordance with Section 9.11 and shall
                                                 ------------
otherwise be on terms and conditions reasonably satisfactory to the Agent, and
until such time as such substitution shall be consummated, the Borrower shall
continue to pay such additional costs.  Upon any such substitution, the Borrower
shall pay or cause to be paid to the Lender that is being replaced, all
principal, interest (to the date of such substitution) and other amounts owing
hereunder to such Lender and such Lender will be released from liability
hereunder.

     (g) Within thirty (30) days after the date of any payment of Taxes, the
Borrower shall furnish to the Agent the original or a certified copy of a
receipt evidencing such payment.

     (h) Without prejudice to the survival of any other agreement of the
Borrower hereunder, the agreements and obligations of the Borrower contained in
this Section 2.5.3.2 shall survive until the first anniversary of the Repayment
     ---------------
Date.

     (i) If the Borrower makes any additional payment to any Lender pursuant to
this Section 2.5.3.2 in respect of any Taxes, and such Lender determines that it
     ---------------
has received (i) a refund of such Taxes, or (ii) a credit against, relief or
remission for, or a reduction in the amount of, any tax or other governmental
charge as a result of any deduction or credit for any Taxes with respect to
which it has received payments under this Section 2.5.3.2, such Lender shall, to
                                          ---------------
the extent that it can do so without prejudice to the retention of such refund,
credit, relief, remission or reduction, pay to the Borrower such amount as shall
be reasonably determined by such Lender to be solely attributable to the
deduction or withholding of such Taxes.  If such Lender later determines that it
was not entitled to such refund, credit, relief, remission or reduction to the
full extent of any payment made pursuant to the first sentence of this Section
                                                                       -------
2.5.3.2(i), the Borrower shall upon demand of such Lender promptly repay the
----------
amount of such overpayment.  Nothing in this Section 2.5.3.2(i) shall be
                                             ------------------
construed as requiring such Lender to conduct its business or to arrange or
alter in any respect its tax or financial affairs so that it is entitled to
receive such a refund, credit or reduction or as allowing any Person to inspect
any records, including tax returns, of such Lender.

               Section 2.6.1.3.  In the event that the Borrower or any
               ------------------
Subsidiary is entitled to receive, collectively, proceeds from any casualty
insurance policies maintained by any of them on account of any interest of the
Borrower and/or any Subsidiary in any property, which proceeds are in an
aggregate amount in excess of $250,000 during the term of this Agreement, such
proceeds shall be received by the Agent and, to the extent that such proceeds
result from a casualty to property of the Borrower and/or any Subsidiary, so
long as no Default or Event of Default exists and is continuing and the Borrower
elects to repair, replace or restore such property, such proceeds shall be
released to the Borrower subject to reasonable procedures and conditions
established by the Agent to the extent necessary to so repair, replace or
restore such property within 4 months (or as soon as reasonably practicable if
such restoration, replacement or repair is not susceptible to being completed
within 4 months) from the date of receipt of such proceeds by the Agent and to
the extent such proceeds are not so used or do not result from such a casualty.
The amount of such proceeds shall permanently reduce the Commitment and to the
extent that the outstanding principal balance of the Loans exceeds the
Commitment as so reduced, the Borrower shall make a prepayment of the Loans for
the accounts of the Lenders in accordance with their Pro Rata Shares upon
written notice from the Agent.

               Section 2.6.1.4.  In the event that the Borrower and/or any

Subsidiary sells, assigns or otherwise transfers title to any asset other than
in the ordinary course of its business for net cash proceeds in the aggregate
since the Closing Date in excess of $250,000, the amount of such proceeds shall
permanently reduce the Commitment and to the extent that the outstanding
principal balance of the Loans exceeds the Commitment as so reduced, the
Borrower shall make a prepayment of the Loans for the accounts of the Lenders in
accordance with their Pro Rate Shares upon written notice from the Agent,
provided, however, that Borrower may sell any of its equipment which is
obsolete, worn-out or no longer used or useful in Borrower's business and
Borrower may use the proceeds of such sale to purchase other equipment which is
useful or necessary in the operation of Borrower's business.

Shares an amount of the outstanding principal balances of the Loans in an amount
equal to that amount necessary to reduce the Borrower's ratio of total

Commitment shall be permanently reduced to an amount which, if fully outstanding
as Loans and Letters of Credit and, without duplication, Letter of Credit
Agreements or unreimbursed amounts drawn thereunder would result in such ratio
being less than 1.0:1.0.

               ---------------
of the Revolving Credit Loans plus the aggregate outstanding stated amounts of
any Letters of Credit and, without duplication, Letter of Credit Agreements and

such extension of time shall in such case be included in the computation of
payment of fees, if any, and interest under this Agreement and under such Note.

     Section 2.8.  Use of Proceeds.  (a)  The Borrower shall use the proceeds of

Rate Election selecting the Libor Rate must be received by the Agent in
accordance with the definition of Interest Rate Election.

          Section 2.9.2.  Libor Loans Unavailable.  Notwithstanding any other
          -------------   -----------------------
provision of this Agreement, if, prior to or on the date on which all or any
portion of the Loans is to be made as or converted into a Libor Loan, any of the
Lenders (or the Agent with respect to (ii) below) shall reasonably determine
(which determination shall be conclusive and binding on the Borrower), that

          (i)   Dollar deposits in the relevant amounts and for the relevant
    Interest Period are not offered to such Lender in the London interbank
    market,

          (ii)  by reason of circumstances affecting the London interbank
    market, adequate and reasonable means do not exist for ascertaining the
    Adjusted Libor Rate, or

<PAGE>

          (iii)  the Adjusted Libor Rate shall no longer represent the effective
    cost to such Lender for Dollar deposits in the London interbank market for
    reasons other than the fact, standing alone, that the Adjusted Libor Rate is
    based on an averaging of rates determined by the Agent and that such
    Lender's rate may exceed such average,

such Lender may elect not to accept any Interest Rate Election electing a Libor
Loan and such Lender shall notify the Agent by telephone or telex thereof,
stating the reasons therefor, not later than the close of business on the second
Business Day prior to the date on which such Libor Loan is to be made.  The
Agent shall promptly give notice of such determination and the reason therefor
to the Borrower, and all or such portion of the Loans, as the case may be, which
are subject to any of Section 2.9.2 (i), (ii) through (iii) as a result of such
                      -------------
Lender's determination shall be made as or converted into, as the case may be,
Prime Rate Loans and such Lender shall have no further obligation to make Libor
Loans, until further written notice to the contrary is given by the Agent to the
Borrower.  If such circumstances subsequently change so that such Lender shall
no longer be so affected, such Lender's obligation to make or maintain its Pro
Rata Share of all or any portion of the Loans as Libor Loans shall be reinstated
when such Lender obtains actual knowledge of such change of circumstances and
promptly after obtaining such actual knowledge such Lender shall forward written
notice thereof to the Agent.  After receipt of such notice, the Agent shall
promptly forward written notice thereof to the Borrower.  Upon or after receipt
by the Borrower of such written notice, the Borrower may submit an Interest Rate
Election in accordance with this Agreement electing an Interest Period ending no
later than the Interest Adjustment Date for the then current Interest Period for
the other Lenders' Pro Rata Shares of Libor Loans and electing the Libor Rate
for such Lenders' or Lender's Pro Rata Share(s) of the Loans as to which such
Lender's or Lenders' obligation(s) to make or maintain its or their Pro Rata
Share(s) of the Loans as Libor Loans was suspended and such Pro Rata Share(s)
shall be converted to Libor Loans in accordance with this Agreement.  During any
period throughout which any of the Lenders has or have no obligation to make or
maintain its or their Pro Rata Share(s) of the Loans as Libor Loans, no Interest
Rate Elections electing the Libor Rate shall be effective with regard to the
Loans to the extent of the Pro Rata Share(s) of such Lender(s), but shall be
effective as to the other Lenders.

          Section 2.9.3.  Libor Lending Unlawful.  In the event that any change
          -------------   ----------------------
in applicable laws or regulations (including the introduction of any new
applicable law or regulation) or in the interpretation thereof (whether or not
having the force of law) by any governmental or other regulatory authority
charged with the administration thereof, shall make it unlawful for any of the
Lenders to make or continue to maintain its Pro Rata Share of all or any portion
of the Loans as Libor Loans, each such Lender shall promptly notify the Agent by
telephone or telex thereof, and of the reasons therefor, and the obligation of
such Lender to make or maintain its Pro Rata Share of the Loans or such portion
thereof as Libor Loans shall, upon the happening of such event, terminate and
the Agent shall, by telephonic notice to the Borrower, declare that such
obligation has so terminated with respect to such Lender, and such Pro Rata
Share of the Loans or any portion thereof to the extent then maintained as Libor
Loans, shall, on the last day on which such Lender can lawfully continue to
maintain such Pro Rata Share of the Loans or any portion thereof as Libor Loans,
automatically convert into Prime Rate Loans without additional cost to the
Borrower.  If circumstances subsequently change so that such Lender shall no
longer be so affected, such Lender's obligation to make or maintain its Pro Rata
Share of all or any portion of the Loans as Libor Loans shall be reinstated when
such Lender

                                       31
<PAGE>

obtains actual knowledge of such change of circumstances, and promptly after
obtaining such actual knowledge such Lender shall forward written notice thereof
to the Agent. After receipt of such notice, the Agent shall promptly forward
written notice thereof the Borrower. Upon or after receipt by the Borrower of
such written notice, the Borrower may submit an Interest Rate Election in
accordance with this Agreement electing an Interest Period ending no later than
the Interest Adjustment Date for the then current Interest Period for the other
Lenders' Pro Rata Shares of Libor Loans and electing the Libor Rate for such
Lenders' or Lender's Pro Rata Share(s) of the Loans as to which such Lender's or
Lenders' obligation(s) to make or maintain its or their Pro Rata Share(s) of the
Loans as Libor Loans was suspended and such Pro Rata Share(s) shall be converted
to Libor Loans in accordance with this Agreement. During any period throughout
which any of the Lenders has or have no obligation to make or maintain its or
their Pro Rata Share(s) of the Loans as Libor Loans, no Interest Rate Elections
electing the Libor Rate shall be effective with regard to the Loans to the
extent of the Pro Rata Share(s) of such Lender(s), but shall be effective as to
the other Lenders.

          Section 2.9.4.  Additional Costs on Libor Loans.  The Borrower further
          -------------   -------------------------------
agrees to pay to the Agent for the account of the applicable Lender or Lenders
such amounts as will compensate any of the Lenders for any increase in the cost
to such Lender of making or maintaining (or of its obligation to make or
maintain) all or any portion of its Pro Rata Share of the Loans as Libor Loans
and for any reduction in the amount of any sum receivable by such Lender under
this Agreement in respect of making or maintaining all or any portion of such
Lender's Pro Rata Share of the Loans as Libor Loans, in either case, from time
to time by reason of:

          (i)   any reserve, special deposit or similar requirement against
    assets of, deposits with or for the account of, or credit extended by, such
    Lender, under or pursuant to any law, treaty, rule, regulation (including,
    without limitation, any Regulations of the Board of Governors of the Federal
    Reserve System) or requirement in effect on or after the date hereof, any
    interpretation thereof by any governmental authority charged with
    administration thereof or by any central bank or other fiscal or monetary
    authority or other authority, or any requirement imposed by any central bank
    or such other authority whether or not having the force of law; or

          (ii)  any change in (including the introduction of any new) applicable
    law, treaty, rule, regulation or requirement or in the interpretation
    thereof by any official authority, or the imposition of any requirement of
    any central bank, whether or not having the force of law, which shall
    subject such Lender to any tax (other than taxes on net income imposed on
    such Lender), levy, impost, charge, fee, duty, deduction or withholding of
    any kind whatsoever or change the taxation of such Lender with respect to
    making or maintaining all or any portion of its Pro Rata Share of the Loans
    as Libor Loans and the interest thereon (other than any change which
    affects, and to the extent that it affects, the taxation of net income of
    such Lender); provided, that with respect to any withholding the foregoing
    shall not apply to any withholding tax described in sections 1441, 1442 or
    3406 of the Code, or any succeeding provision of any legislation that
    amends, supplements or replaces any such section, or to any tax, levy,
    impost, duty, charge, fee, deduction or withholding that results from any
    noncompliance by a Lender with any federal, state or foreign law or from any
    failure by a Lender to file or furnish any report, return, statement or form
    the filing or

                                       32
<PAGE>

    furnishing of which would not have an adverse effect on such Lender and
    would eliminate such tax, impost, duty, deduction or withholding;

In any such event, such Lender shall promptly notify the Agent thereof, and of
the reasons therefor, and the Agent shall promptly notify the Borrower thereof
in writing stating the reasons provided to the Agent by such Lender therefor and
the additional amounts required to fully compensate such Lender for such
increased or new cost or reduced amount as reasonably determined by such Lender.
Such additional amounts shall be payable on each date on which interest is to be
paid hereunder or, if there is no outstanding principal amount under any of the
Notes, within 10 Business Days after the Borrower's receipt of said notice.
Such Lender's certificate as to any such increased or new cost or reduced amount
(including calculations, in reasonable detail, showing how such Lender computed
such cost or reduction) shall be submitted by the Agent to the Borrower and
shall, in the absence of manifest error, be conclusive.  In determining any such
amount, the Lender(s) may use any reasonable averaging and attribution methods.
Notwithstanding anything to the contrary set forth above, the Borrower shall not
be obligated to pay any amounts pursuant to this Section 2.9.4 as a result of
                                                 -------------
any requirement or change referenced above with respect to any period prior to
the one hundred and eightieth (180th) day prior to the date on which the
Borrower is first notified thereof (other than any amounts which relate to any
such requirement or change which is adopted with retroactive effect in which
case the Borrower shall be obligated to pay all such amounts accrued from the
date as of which such requirement or change is retroactively effective) unless
the failure to give such notice within such one hundred and eighty (180) day
period resulted from reasonable circumstances beyond such Lender's reasonable
control.

          Section 2.9.5.  Libor Funding Losses.  In the event that any payment
          -------------   --------------------
or prepayment of a Libor Loan is received on a date other than the last day of
an Interest Period, such payment or prepayment shall be held by the Agent in a
separate account and be pledged to the Agent as collateral for the obligations
of the Borrower arising in connection with this Agreement, the Notes and the
other Financing Documents until the end of the then current Interest Period, at
which time the Agent shall apply such payment or prepayment, for the accounts of
the Lenders in accordance with their Pro Rata Shares, to the outstanding Libor
Loans.  Notwithstanding the foregoing, in the event any of the Lenders shall
incur any loss or expense (including, without limitation, any loss or expense
incurred by reason of the liquidation or reemployment of deposits or other funds
acquired by such Lender to fund or maintain all or any portion of the Loans as
Libor Loans) as a result of:

          (i)   payment or prepayment by the Borrower of all or any portion of
    any Libor Loan on a date other than the Interest Adjustment Date for such
    Libor Loan, for any reason; provided, however that this clause shall not be
    deemed to grant the Borrower any right to convert a Libor Loan to a Prime
    Rate Loan prior to the end of any Interest Period or to imply such right;

          (ii)  conversion of all or any portion of any Libor Loan on a day
    other than the last day of an Interest Period applicable to such Loan to a
    Prime Rate Loan for any reason including, without limitation, acceleration
    of the Loans upon or after an Event of Default, any Interest Rate Election
    or any other cause whether voluntary or involuntary and whether

                                       33

    or not referred to or described in this Agreement, other than any such
    conversion resulting solely from application of Sections 2.9.2 or 2.9.3 by
                                                    --------------    -----
    any Lender; or

          (iii)  any failure by the Borrower to borrow the Loans as Libor Loans
    on the date specified in any Interest Rate Election selecting the Libor
    Rate, other than any such failure resulting solely from application of
    Sections 2.9.2 or 2.9.3 by any Lender;
    --------------    -----

such Lender shall promptly notify the Agent thereof, and of the reasons
therefor.  Upon the request of the Agent, the Borrower shall pay directly to the
Agent for the account of such Lender such amount as will (in the reasonable
determination of such  Lender, which shall be conclusive in the absence of
manifest error)  reimburse such Lender for such loss or expense.  Each Lender
shall furnish to the Borrower, upon written request from the Borrower received
by the Agent, a written statement setting forth the computation of any such
amounts payable to such Lender under this Section 2.9.5.

or 2.9.5, such Lender will exercise all reasonable efforts to take such
   -----
reasonable actions at no expense to such Lender or the Borrower (other than
reasonable expenses which are covered by the Borrower's advance deposit of funds
with such Lender for such purpose, or if such Lender agrees, which the Borrower
has agreed to pay or reimburse to such Lender in full upon demand), in
accordance with such Lender's usual banking practices in such situations and
subject to any statutory or regulatory requirements applicable to such Lender,
as such Lender may take without the consent or participation of any other Person
to, in the case of an event described in Sections 2.2.3 and/or 2.9.4 or 2.9.5,

other interbank Libor market in which such Lender regularly participates and in
which the applicable determination(s) described in Sections 2.9.2(i), (ii) or

and conditions of this Agreement, to convert such Lender's Pro Rata Share to a
Prime Rate Loan by making Interest Rate Elections for Interest Periods which (i)
end on the Interest Adjustment Date for such Libor Loan or (ii) end on Business
Days occurring prior to such Interest Adjustment Date, in which case, at the end
of the last of such Interest Periods any such Libor Rate Loan shall
automatically convert to a Prime Rate Loan and the Borrower shall have no
further right to make an Interest Rate Election with respect to such Prime Rate
Loan other than an Interest Rate Election which is effective on the Interest
Adjustment Date for such Libor Loan.  The Borrower's options set forth in this
Section 2.9.7 may be exercised, if and only if the Borrower pays, concurrently

Lender or Lenders, the Borrower shall have the right to substitute another bank
satisfactory to the Agent for such Lender which is entitled to such additional
costs or which is relieved from making Libor Loans and the Agent shall use
reasonable efforts (with all reasonable costs of such efforts by the Agent to be
borne by the Borrower) to assist the Borrower to locate such substitute bank.
Any such substitution shall take place in accordance with Section 9.11 and

be made as though each Lender  actually funded its relevant Libor Loans through
the purchase of a deposit in the London interbank market bearing interest at the
Libor Rate in an amount equal to that Libor Loan and having a maturity
comparable to the relevant Interest Period and through the transfer of such
deposit from an offshore office of such Lender to a domestic office of such
Lender in the United States of America; provided, however, that each Lender may
fund each of its Libor Loans in any manner it sees fit and the foregoing
assumption shall be utilized solely for the calculation of amounts payable under

unreimbursed amounts drawn thereunder first exceeds $5,000,000, the Borrower
shall enter into an interest rate protection arrangement with the Agent covering
not less than 50% of such outstanding amount.  Such interest rate protection
arrangement may consist of any one or a combination of the following: (i) the
purchase of an interest rate swap arrangement covering such Loans and such
Letter of Credit amounts effectively converting the Borrower's interest payment
obligations with respect to such portion of the Loans and Letter of Credit
amounts to a fixed rate per annum equal to the then Libor Rate, plus two percent
(2%) for a term expiring not earlier than the second anniversary of the date of
such interest rate swap arrangement or (ii) the purchase of an interest rate cap
covering such Loans and such Letter of Credit amounts at a cap rate per annum
equal to the then Libor Rate, plus two percent (2%) for a term expiring not
earlier than said second anniversary date.  The other terms and conditions of

and/or any such Subsidiary would draw into question the legal existence of the

authorization and/or enforceability of any of the Financing Documents and/or any
provision thereof and/or could not reasonably be

                                       41

for those taxes, if any, which are being contested in good faith and by

been made in accordance with GAAP and except where any failure to file or pay
could not reasonably be expected to have a Material Adverse Effect on the
Borrower, the Parent or any Subsidiary and except as described in Exhibit 4.1.9.
                                                                  -------------

Revenue Service of any minimum funding requirement under section 412 of the
Code.  Borrower and any Commonly Controlled Entity have not incurred any
liability to the PBGC in connection with any Plan covering any employees of
Borrower or any Commonly Controlled Entity in amount exceeding Fifty Thousand
Dollars ($50,000) in the  aggregate or ceased operations at any facility or
withdrawn from any Plan in a manner which could subject any of them to liability
under sections 4062(e), 4063 or 4064 of ERISA in amount exceeding  Fifty
Thousand Dollars ($50,000) in the aggregate, and know of no facts or
circumstance which might give rise to any liability of  Borrower or any Commonly
Controlled Entity to the PBGC under Title IV of ERISA in amount exceeding Fifty
Thousand Dollars ($50,000) in the aggregate.  Borrower and any Commonly
Controlled Entity have not incurred any withdrawal

                                       42
<PAGE>

liability in amount exceeding Fifty Thousand Dollars ($50,000) in the aggregate
(including but not limited to any contingent or secondary withdrawal liability)
within the meaning of sections 4201 and 4202 of ERISA, to any Multiemployer
Plan, and no event has occurred, and there exists no condition or set of
circumstances known to the Borrower, which presents a risk of the occurrence of
any withdrawal from or the partition, termination, reorganization or insolvency
of any Multiemployer Plan which could result in any liability to a Multiemployer
Plan in amount exceeding Fifty Thousand Dollars ($50,000) in the aggregate.


          Except for payments for which the minimum funding  requirement has
been waived under section 412 of the Code, full payment has been made of all

agreement relating to any Plan to which Borrower or any  Commonly Controlled

adequate provision for reserves to meet contributions that have not been made
because they are not yet due under the terms of any Plan or related agreements.


          Neither Borrower nor any Commonly Controlled Entity has any knowledge,
nor do any of them have any reason to believe, that any Reportable Event which
could result in a liability or liabilities of Fifty Thousand Dollars ($50,000)
or more in the aggregate has occurred with respect to any Plan.

beneficiary of any of the provisions hereof.  In performing its functions and

assume nor shall the Agent be deemed to have assumed any obligation towards or
relationship of agency or trust with or for the Borrower, any of the
Stockholders, any Affiliate or any Subsidiary.

     Section 8.2.  Powers; General Immunity.
     -----------   ------------------------

powers as

                                       63

responsibilities which are expressly specified in this Agreement or in any of
the Financing Documents and may perform such duties by or through its agents or
employees. The duties of the Agent shall be mechanical and administrative in
nature; and the Agent shall not have by reason of this Agreement or any of the
Financing Documents a fiduciary relationship in respect of any Lender; and
nothing in this Agreement or any of the Security Documents, expressed or
implied, is intended to or shall be so construed as to impose upon the Agent any
obligations in respect of this Agreement or any of the Financing Documents or
the other instruments and agreements referred to herein except as expressly set
forth herein or therein.

hereafter executed in connection herewith or therewith, or for any
representations, warranties, recitals or statements made herein or therein or
made in any written or oral statement or in any financial or other statements,
instruments, reports, certificates or any other documents in connection herewith
or therewith by or on behalf of the Borrower, any of the Affiliates, and/or any
Subsidiary to the Agent or any Lender, or be required to ascertain or inquire as
to the performance or observance of any of the terms, conditions, provisions,
covenants or agreements contained herein or therein or as to the use of the
proceeds of the Loans or of the existence or possible existence of any Default
or Event of Default.

          Section 8.2.3.  Exculpatory Provisions.  Neither the Agent nor any of
          -------------   ----------------------
its officers, directors, employees or agents shall be liable to any Lender for
any action taken or omitted  hereunder or under any of the Financing Documents,
or in connection herewith or therewith unless caused by its or their gross
negligence or willful misconduct.  If the Agent shall request instructions from
Lenders with respect to any action (including the failure to take an action) in
connection with any of the Financing Documents, the Agent shall be entitled to
refrain from taking such action unless and until the Agent, shall have received
instructions from the Majority Lenders (or all of the Lenders if the action
requires their consent).  Without prejudice to the generality of the foregoing,
(i) the Agent shall be entitled to rely, and shall be fully protected in
relying, upon any communication, instrument or document believed by it to be
genuine and correct and to have been signed or sent by the proper person or
persons, and shall be entitled to rely and shall be protected in relying on
opinions and judgments of attorneys (who may be attorneys for the Borrower, any
of the Affiliates, and/or any Subsidiary), accountants, experts and other
professional advisors selected by it; and (ii) no Lender shall have any right of
action whatsoever against the Agent as a result of the Agent acting or (where so
instructed) refraining from acting under any of the Financing Documents or the
other instruments and agreements referred to herein in accordance with the
instructions of the Majority Lenders (or all of the Lenders if the action
requires their consent).  The Agent shall be entitled to refrain from exercising
any power, discretion or authority vested in it under any of the Financing
Documents or the other instruments and agreements referred to herein unless and
until it has obtained the instructions of the Majority Lenders (or all of the
Lenders if the action requires their consent).

          Section 8.2.4.  Agent Entitled to Act as Lender.  The agency hereby
          -------------   -------------------------------
created shall in no way impair or affect any of the rights and powers of, or
impose any duties or obligations upon, Fleet in its individual capacity as a
Lender hereunder.  With respect to its participation in

                                       64

the Loans and the Commitment, Fleet shall have the same rights and powers
hereunder as any other Lender and may exercise the same as though it were not
performing the duties and functions delegated to it hereunder, and the term
"Lender" or "Lenders" or any similar term shall, unless the context clearly
otherwise indicates, include Fleet in its individual capacity. The Agent and its
affiliates may accept deposits from, lend money to and generally engage in any
kind of banking, trust, financial advisory or other business with the Borrower,
any of the Stockholders, or any Affiliate or Subsidiary as if it were not
performing the duties specified herein, and may accept fees and other
consideration from the Borrower and/or any of such other Persons for services in
connection with this Agreement and otherwise without having to account for the
same to Lenders.

     Section 8.3.  Representations and Warranties; No Responsibility for
     -----------   -----------------------------------------------------
Appraisal of Creditworthiness.  Each Lender represents and warrants that it has
-----------------------------
made its own independent investigation of the financial condition and affairs of
the Borrower, the Stockholders and any Subsidiaries of any of them in connection
with the making of the Loans hereunder and has made and shall continue to make
its own appraisal of the creditworthiness of the Borrower, the Stockholders and
the Subsidiaries.  The Agent shall not have any duty or responsibility, either
initially or on a continuing basis, to make any such investigation or any such
appraisal on behalf of Lenders or to provide any Lender with any credit or other
information with respect thereto whether coming into its possession before the
making of any Loan or any time or times thereafter (except for information
received by the Agent under Section 5.3 hereof which the Agent will promptly
                            -----------
forward to the Lenders), and the Agent shall further not have any responsibility
with respect to the accuracy of or the completeness of the information provided
to any of the Lenders.

     Section 8.4.  Right to Indemnity.  Each Lender severally agrees to
     -----------   ------------------
indemnify the Agent proportionately to its Pro Rata Share of the Loans, to the
extent the Agent shall not have been reimbursed by or on behalf of the Borrower,
for and against any and all liabilities, obligations, losses, damages,
penalties, actions, judgments, suits, costs, expenses (including, without
limitation, counsel fees and disbursements) or disbursements of any kind or
nature whatsoever which may be imposed on, incurred by or asserted against the
Agent in performing its duties hereunder or in any way relating to or arising
out of this Agreement and/or any of the other Financing Documents; provided that
                                                                   --------
no Lender shall be liable for any portion of such liabilities, obligations,
losses, damages, penalties, actions, judgments, suits, costs, expenses or
disbursements resulting from the Agent's gross negligence or willful misconduct.
If any indemnity furnished to the Agent for any purpose shall, in the opinion of
the Agent, be insufficient or become impaired, the Agent may call for additional
indemnity and cease, or not commence, to do the acts indemnified against until
such additional indemnity is furnished.

     Section 8.5.  Payee of Note Treated as Owner.  The Agent may deem and treat
     -----------   ------------------------------
the payee of any Note as the owner thereof for all purposes hereof unless and
until a written notice of the assignment or transfer thereof shall have been
filed with the Agent.  Any request, authority or consent of any person or entity
who, at the time of making such request or giving such authority or consent, is
the holder of any Note shall be conclusive and binding on any subsequent holder,
transferee or assignee of that Note or of any Note or Notes issued in exchange
for such Note.

          Section 9.1.1.  Except to the extent prohibited by applicable law, the
          -------------
Borrower irrevocably:


          Section 9.1.1.1.  agrees that any suit, action, or other legal
          ---------------
proceeding arising out of any of the Financing Documents or any of the Loans may
be brought in the courts of record of the Commonwealth of Massachusetts or any
other state(s) in which any of the Borrower's or any Subsidiary's assets are
located or the courts of the United States located in the Commonwealth of
Massachusetts or any other state(s) in which any of the Borrower's or any
Subsidiary's assets are located;


          Section 9.1.1.2.  consents to the jurisdiction of each such court
          ---------------
in any such suit, action or proceeding; and


          Section 9.1.1.3.  waives any objection which it may have to the laying
          ---------------
of venue of such suit, action or proceeding in any of such courts.


     For such time as any of the Indebtedness of the Borrower to any Lender
and/or the Agent shall be unpaid in whole or in part and/or the Commitment is in
effect, the Borrower irrevocably designates the registered agent or agent for
service of process of the Borrower as reflected in the records of the Secretary
of State of the Commonwealth of Pennsylvania as its registered agent, and, in
the absence thereof, the Secretary of State of the Commonwealth of Pennsylvania
as its agent to accept and acknowledge on its behalf service of any and all
process in any such suit, action or proceeding brought in any such court and
agrees and consents that any such service of process upon such agent and written
notice of such service to the Borrower by registered or certified mail shall be
taken and held to be valid personal service upon the Borrower regardless of
where the Borrower shall then be doing business and that any such service of
process shall be of the same force and validity as if service were made upon it
according to the laws governing the validity and requirements of such service in
each such state and waives any claim of lack of personal service or other error
by reason of any such service.  Any notice,  process, pleadings or other papers
served upon the aforesaid designated agent shall, within three (3) Business Days
after such service, be sent by the method provided therefor under Section 9.6 to
                                                                  -----------
the Borrower at its address set forth in this Agreement.  BORROWER, AGENT AND
LENDERS MUTUALLY HEREBY KNOWINGLY, VOLUNTARILY AND INTENTIONALLY WAIVE THE RIGHT
TO A TRIAL BY JURY IN RESPECT OF ANY CLAIM BASED HEREON, ARISING OUT OF, UNDER
OR IN CONNECTION WITH THIS AGREEMENT, ANY NOTE OR ANY OTHER LOAN DOCUMENTS
CONTEMPLATED TO BE EXECUTED IN CONNECTION HEREWITH OR ANY COURSE OF CONDUCT,
COURSE OF DEALINGS, STATEMENTS (WHETHER VERBAL OR WRITTEN) OR ACTIONS OF ANY
PARTY.  THIS WAIVER CONSTITUTES A MATERIAL INDUCEMENT FOR EACH OF THE LENDERS TO
ENTER INTO THIS AGREEMENT, ACCEPT ITS NOTE AND MAKE THE LOANS.


     Section 9.2.  Rights and Remedies Cumulative.  No right or remedy conferred
     -----------   ------------------------------
upon or reserved to the Agent and/or the Lenders in any of the Financing
Documents is intended to be exclusive of any other right or remedy, and every
right and remedy shall, to the extent permitted by law, be cumulative and in
addition to every other right and remedy given under any of the Financing
Documents or now or hereafter existing at law or in equity or otherwise.  The

                                       67
<PAGE>

assertion or employment of any right or remedy under any of the Financing
Documents, or otherwise, shall not prevent the concurrent assertion or
employment of any other appropriate right or remedy.


     Section 9.3.  Delay or Omission not Waiver.  No delay in exercising or
     -----------   ----------------------------
failure to exercise by the Agent and/or the Lenders of any right or remedy
accruing upon any Default or Event of Default shall impair any such right or
remedy or constitute a waiver of any such Default or Event of Default or an
acquiescence therein.  Every right and remedy given by any of the Financing
Documents or by law to the Agent  and/or any of the Lenders may be exercised
from time to time, and as often as may be deemed expedient, by the Agent and/or
any of the Lenders.


     Section 9.4.  Waiver of Stay or Extension Laws.  The Borrower covenants (to
     -----------   --------------------------------
the extent that it may lawfully do so) that it will not at any time insist upon,
or plead or in any manner whatsoever claim or take the benefit or advantage of,
any stay or extension law wherever enacted, now or at any time hereafter in
force, which may affect the covenants or the performance of any of the Financing
Documents; and the Borrower (to the extent that it may lawfully do so) hereby
expressly waives all benefit and advantage of any such law and covenants that it
will not hinder, delay or impede the execution of any power herein granted to
the Agent and/or any of the Lenders, but will suffer and permit the execution of
every such power as though no such law had been enacted, except to the extent
the Agent or any Lender is guilty of willful misconduct or gross negligence.


     Section 9.5.  Amendments, etc.  No amendment, modification, termination, or
     -----------   ---------------
waiver of any provision of any of the Financing Documents nor consent to any
departure by the Borrower therefrom  shall in any event be effective unless the
same shall be in a written notice given to the Borrower by the Agent and
consented to in writing by the Majority Lenders (or by the Agent acting alone if
any specific provision of this Agreement provides that the Agent, acting alone,
may grant such amendment, modification, termination, waiver or departure) and
the Agent shall give any such notice if the Majority Lenders so consent or
direct the Agent to do so; provided, however, that any such amendment,
modification, termination, waiver or consent shall require a written notice
given to the Borrower by the Agent and consented to in writing by all of the
Lenders if the effect thereof is to (i) change any of the provisions affecting
the interest rate or fees on the Loans so as to reduce said interest rate or
fees, (ii) extend or modify the Commitment, (iii) discharge or release the
Borrower from its obligation to repay all principal due under the Loans or
release any collateral or guaranty for the Loans, (iv) change any Lender's Pro

change the definition of Majority Lenders, (vii) extend any scheduled due date
for payment of principal, interest or fees or (viii) permit the Borrower to
assign any of its rights under or interest in this Agreement, and then such
waiver or consent shall be effective only in the specific instance and for the
specific purpose for which given.  Any amendment or modification of this
Agreement must be signed by the Borrower, the Agent and at least all of the
Lenders consenting thereto who shall then hold the Pro Rata Shares of the Loans
required for such amendment or modification under this Section 9.5 and the Agent
                                                       -----------
shall sign any such amendment if such Lenders so consent or direct the Agent to
do so provided that any Lender dissenting therefrom shall be given an
opportunity to sign any such amendment or modification.  Any amendment of any of
the Security Documents must be signed by each of the parties thereto.  No notice
to or demand on the Borrower and no consent, waiver or departure from the terms
of this Agreement granted by

                                       68

upon and inure to the benefit of the Borrower, the Agent and the Lenders and

assume such of the obligations of each Selling Lender under the Financing
Documents as may be specified in such Assignment and Acceptance and this
Agreement shall be amended by execution and delivery of each Substitution
Agreement to include such Substituted Lender as a Lender for all

                                       71
<PAGE>

purposes under the Financing Documents and to substitute for the then existing

and regular on its face as to its contents and appears to be signed on behalf of
the Substituted Lender which is a party thereto, and the Agent shall have no
liability or responsibility to any party as a consequence of relying thereon and
acting in accordance with and countersigning any such Assignment and Acceptance.
The effective date of each Assignment and Acceptance shall be the date specified
as such therein and each Lender prior to such effective date shall, for all
purposes hereunder, be deemed to have and possess all of their respective rights
and obligations hereunder up to 12:00 o'clock Noon on the effective date

Acceptance pursuant to and in accordance with this Section 9.11 and acceptance
                                                   ------------

hereof without which such Assignment and Acceptance shall be ineffective): (i)
except as provided hereunder and in Section 9.11.5, the respective rights of
                                    --------------
each Selling Lender and the Borrower against each other under the Financing
Documents with respect to the portion of the Loans being assigned or delegated
shall be terminated and each Selling Lender and the Borrower shall each be
released from all further obligations to the other hereunder with respect

referred to in this Section 9.11 as "Discharged Rights and Obligations"); and
                    ------------
(ii) the Borrower and the Substituted Lender shall each acquire rights against
each other and assume obligations towards each other which differ from  the
Discharged Rights and Obligations only in so far as the Borrower and the
Substituted Lender have assumed and/or acquired the same in place of the Selling
Lender in question; and (iii) the Agent, the Substituted Lender and the other
Lenders shall acquire the same rights and assume the same obligations between
themselves as they would have acquired and assumed had such Substituted Lender
been an original party to this Agreement as a Lender possessing the Discharged
Rights and Obligations acquired and/or assumed by it in consequence of the
delivery of such Assignment and Acceptance to the Agent.

     ------------   -----------------
receipt of each payment from or on behalf of the Borrower in respect of any
obligations of the Borrower  hereunder it shall distribute such payment to the
Lenders pro rata based upon their respective Pro Rata Shares, if any, of the

Lenders agrees that, if it should receive any amount hereunder (whether by
voluntary payment, by realization upon security, by the exercise of the right of
setoff under Section 2.5.2 or otherwise or banker's lien, by counterclaim or

all of the Lenders immediately prior to such receipt, except for any amounts
received pursuant to Section 2.2.3, then such Lender receiving such excess
                     -------------
payment shall purchase for cash without recourse or warranty from the

other Lenders an interest in the Obligations of the Borrower to such Lenders in
such amount as shall result in a proportional participation by all the Lenders
in such amount; provided further, however, that if all or any portion of such
excess amount is thereafter recovered from such Lender, such purchase shall be
rescinded and the purchase price restored to the extent of such recovery, but
without interest.


     Section 9.13.  Indemnification.  The Borrower irrevocably agrees to and
     ------------   ---------------
does hereby indemnify and hold harmless Agent and each of the Lenders, their
agents or employees and each Person, if any, who controls any of the Agent and
the Lenders within the meaning of Section 15 of the Securities Act of 1933, as
amended, and each and all and any of them (the "Indemnified Parties"), against
any and all losses, claims, actions, causes of action, damages or liabilities
(including any amount paid in settlement of any action, commenced or threatened
and any amount described in Section 8.4) (collectively, the "Damages"), joint or
                            -----------
several, to which they, or any of them, may become subject under statutory law
or at common law, and to reimburse the Indemnified Parties for any legal or
other out-of-pocket expenses reasonably incurred by it or them in connection
with investigating, preparing for or defending against any of the Indemnified
Parties, insofar as such losses, claims, damages, liabilities or actions arise
out of or are related to any act or omission of the Borrower and/or any
Subsidiary with respect to any of (i) the Related Transactions, (ii) any of the
Financing Documents, (iii) any of Loans, (iv) any use made or proposed to be
made with the proceeds of the Loans, (v) any acquisition or proposed acquisition
or any other similar business combination or proposed business combination by
the Borrower and/or any of its Subsidiaries and/or its Affiliates (whether by
acquisition or exchange of capital stock or other securities or by acquisition
of all or substantially all of the assets of any Person), (vi) any offering of
securities by the Borrower and/or any Subsidiary after the date hereof and/or in
connection with the Securities and Exchange Act of 1933 and/or (vii) any failure
to comply with any applicable federal, state or foreign governmental law, rule,
regulation, order or decree, including without limitation, any Damages which
arise out of or are based upon any untrue statement or alleged untrue statement
of a material fact with respect to matters relative to any of the foregoing
contained in any document distributed in connection therewith, or the omission
or alleged omission to state in any of the foregoing a material fact necessary
to make the statements therein, in the light of the circumstances under which
they were made, not misleading, but excluding any Damages to the extent arising
from or due to, as determined in a final nonappealable judgment by a court of
competent jurisdiction, the gross negligence or willful misconduct of any of the
Indemnified Parties; provided, however, that notwithstanding the foregoing, no
Indemnified Party shall have any liability (whether direct or indirect, in
contract or tort of otherwise) to the Borrower, any Affiliates or any
Subsidiaries or to their respective security holders or creditors except for
direct (as opposed to consequential) damages determined in a final nonappealable
judgment by a court of competent jurisdiction to have resulted from such
Indemnified Party's gross negligence or willful misconduct.  In the case of an
investigation, litigation or proceeding to which the indemnity described in this
paragraph applies, such indemnity shall be effective whether or not such
investigation, litigation or proceeding is brought by the Borrower, any
Affiliates or any Subsidiary or to their respective security holders or
creditors or an Indemnified Party or an Indemnified Party is otherwise a party
thereto and whether or not the Related Transaction and the transactions
contemplated by the Financing Documents are consummated.

                                       74

     Promptly upon receipt of notice of the commencement of any action, or
information as to any threatened action against any of the Indemnified Parties
in respect of which indemnity or reimbursement may be sought from the Borrower
on account of the agreement contained in this Section 9.13, notice shall be
                                              ------------
given to the Borrower in writing of the commencement or threatening thereof,
together with a copy of all papers served, but the omission so to notify the
Borrower of any such action shall not release the Borrower from any liability
which it may have to such Indemnified Parties unless, and only to the extent
that, such omission materially prejudiced Borrower's ability to defend against
such action.


     In case any such action shall be brought against any of the Indemnified
Parties, the Borrower shall be entitled to participate in (and, to the extent
that it shall wish, to select counsel and to direct) the defense thereof at its
own expense.  Any of the Indemnified Parties shall have the right to employ its
or their own counsel in any case, but the fees and expenses of such counsel
shall be at the expense of such Indemnified Party unless the employment of such
counsel shall have been authorized in writing by the Borrower in connection with
the defense of such action or the Borrower shall not have employed counsel to
have charge of the defense of such action or such Indemnified Party shall have
received an opinion from an independent counsel that there may be defenses
available to it which are different from or additional to those available to the
Borrower (in which case the Borrower shall not have the right to direct the
defense of such action on behalf of such Indemnified Party), in any of which
events the same shall be borne by the Borrower.  If any Indemnified Party
settles any claim or action with respect to which the Borrower has agreed to
indemnify such Indemnified Party pursuant to the terms hereof, the Borrower
shall have no liability pursuant to this Section 9.13 to such Indemnified Party
                                         ------------
with respect to such claim or action unless the Borrower shall have consented in
writing to the terms of such settlement.


     The provisions of Section 9.13 shall be effective only to the fullest
                       ------------
extent permitted by law.  The provisions of this Section 9.13 shall continue in
                                                 ------------
effect and shall survive (among other events), until the applicable statute of
limitations has expired, any termination of this Agreement, foreclosure, a deed
in lieu transaction, payment and satisfaction of the Obligations of Borrower,
and release of any collateral for the Loans.


     Section 9.14.  Confidential Information.  The Lenders and the Agent shall,
     ------------   ------------------------
with respect to any and all financial statements or other reports or documents
delivered by or on behalf of the Borrower or any related parties to the Lenders
or the Agent pursuant to Section 5.3 and any other information provided to any
Lender or the Agent (other than in a public forum, including an analyst's
meeting and other than any such information which is publicly available other
than solely as a result of disclosure by the Agent or any of the Lenders) and to
the extent that such information therein contained or provided has not
theretofore otherwise been disclosed in such a manner as to render such
information no longer confidential (other than as a result of disclosure by the
Agent or a Lender in violation of its obligation hereunder), employ reasonable
procedures designed to maintain the confidential nature of the information
therein contained; provided, however, that any Lender or the Agent may disclose
or disseminate such information to:  (a) such Lender's or the Agent's respective
employees, agents, attorneys and accountants who would ordinarily have access to
such information in the normal course of the performance of their duties in
connection with the administration of the Loans; (b) such third parties as such
Lender or the Agent may, in its discretion, deem reasonably necessary in
connection with or in

                                       75
<PAGE>

response to (i) compliance with any law, ordinance or governmental order,
regulation, rule, subpoena, or investigation, or (ii) any order, decree,
judgment, subpoena, notice of discovery or similar ruling or pleading issued,
filed, served or purported on its face to be issued, filed or served (x) by or
under authority of any court, tribunal, arbitration board or any governmental
agency, commission, authority board or similar entity or (y) in connection with
any proceeding, case or matter pending (or on its face purported to be pending)
before any court, tribunal, arbitration board or any governmental agency,
commission, authority, board or similar entity; provided that without notice to
the Borrower, the Agent and any Lender may disclose such information to bank
examiners of governmental agencies having regulatory authority over the Agent or
such Lender in question in connection with such examiner's examinations of Agent
or such Lender's books and records, or (iii) collection by judicial proceeding
of any of the Indebtedness now or hereafter owing by the Borrower and/or any
Subsidiary to the Agent and/or any of the Lenders or enforcement of any rights
or remedies now or hereafter possessed by Agent and/or any of the Lenders
pursuant to this Agreement, any of the Notes or any of the other Financing
Documents; (c) subject to Section 9.11, any prospective purchaser (including an
                          ------------
affiliate of any Lender), in connection with the resale or proposed resale by it
of any portion of its Notes or other participation in its Pro Rata Share of the
Loans; provided that the prospective participant has signed an agreement binding
such participant under this Section 9.14 as if it were a Lender; and (d) any
                            ------------
entity utilizing such information to rate or classify any Lender's or the
Agent's debt or equity securities for sale to the public; provided that such
rating agency has agreed to keep such information confidential pursuant to an
agreement reasonably satisfactory to the Borrower.


     Section 9.15.  Governing Law.  This Agreement and each Note shall be
     ------------   -------------
governed by, and construed in accordance with, the laws of The Commonwealth of
Massachusetts without regard to such state's conflict of laws rules.


     Section 9.16.  Severability of Provisions.  Any provision of this Agreement
     ------------   --------------------------
which is prohibited or unenforceable in any jurisdiction shall, as to such
jurisdiction, be ineffective to the extent of such prohibition or
unenforceability without invalidating the remaining provisions hereof or
affecting the validity or enforceability of such provision in any other
jurisdiction.


     Section 9.17.  Headings.  Article and Section headings in this Agreement
     ------------   --------
are included herein for convenience of reference only and shall not constitute a
part of this Agreement for any other purpose.


     Section 9.18.  Counterparts.  This Agreement may be executed and delivered
     ------------   ------------
in any number of counterparts each of which shall be deemed an original, and
this Agreement shall be effective when at least one counterpart hereof has been
executed by each of the parties hereto.
