Agent for the benefit of the Banks and the Agent as cash collateral for all
Reimbursement Obligations, and



     (c)  upon the termination of the Total Commitment or the acceleration of
the Reimbursement Obligations with respect to all Letters of Credit in
accordance with Section 12, an amount equal to the then Maximum Drawing Amount
of all Letters of Credit, which amount shall be held by the Agent for the
benefit of the Banks and the Agent as cash collateral for all Reimbursement
Obligations.


          Each such payment shall be made to the Agent at the Agent's Head
          Office in immediately available funds.  Interest on any and all
          amounts remaining unpaid by the Borrower under this Section 3A.2 at
          any time from the date such amounts become due and payable (whether as
          stated in this Section 3A.2, by acceleration or otherwise) until
          payment in full (whether before or after judgment) shall be payable to
          the Agent on demand at the rate specified in Section 4.11 for overdue
          principal of the Loans.

or other demand for payment shall be made under any Letter of Credit, the Agent

Section 3A.2 on or before the date that such draft is paid or other payment is
made by the Agent, the Agent may at any time thereafter notify the Banks of the
amount of any such Unpaid Reimbursement Obligation.  No later than 3:00 p.m.
(Boston time) on the Business Day next following the receipt of such notice,
each Bank shall make available to the Agent, at its Head Office, in immediately
available funds, such Bank's Commitment Percentage of such Unpaid Reimbursement
Obligation, together with an amount equal to the product of (i) the average,
computed for the period referred to in clause (iii) below, of the weighted
average interest rate paid by the Agent for federal funds acquired by the Agent
during each day included in such period, TIMES (ii) the amount equal to such
Bank's Commitment Percentage of such Unpaid Reimbursement Obligation, TIMES
(iii) a fraction, the numerator of which is the number of days that elapse from
and including the date the Agent paid the draft presented for honor or otherwise
made payment to the date on which such Bank's Commitment Percentage of such
Unpaid Reimbursement Obligation shall become immediately available to the Agent,
and the denominator of which is 360.  The responsibility of the Agent to the
Borrower and the Banks shall be only to determine that the documents (including
each draft) delivered under each Letter of Credit in connection with such
presentment shall be in conformity in all material respects with such Letter of
Credit.

Section 3A shall be absolute and unconditional under any and all circumstances
and irrespective of the occurrence of any Default or Event of Default or any
condition precedent whatsoever or any setoff, counterclaim or defense to payment
which the Borrower may have or have had against the Agent, any Bank or any
beneficiary of a Letter of Credit.  The Borrower further agrees with the Agent
and the Banks that the Agent and the Banks shall not be responsible for, and the
Borrower's Reimbursement Obligations under Section 3A.2




                                      -16-

shall not be affected by, among other things, the validity or genuineness of
documents or of any endorsements thereon, even if such documents should in fact
prove to be in any or all respects invalid, fraudulent or forged, or any dispute
between or among the Borrower, the beneficiary of any Letter of Credit or any
financing institution or other party to which any Letter of Credit may be
transferred or any claims or defenses whatsoever of the Borrower against the
beneficiary of any Letter of Credit or any such transferee.  The Agent and the
Banks shall not be liable for any error, omission, interruption or delay in
transmission, dispatch or delivery of any message or advice, however
transmitted, in connection with any Letter of Credit.  The Borrower agrees that
any action taken or omitted by the Agent or any Bank under or in connection with
each Letter of Credit and the related drafts and documents, if done in good
faith, shall be binding upon the Borrower and shall not result in any liability
on the part of the Agent or any Bank to the Borrower.



     Section 3A.5.  RELIANCE BY ISSUER.  To the extent not inconsistent with
Section 3A.4, the Agent shall be entitled to rely, and shall be fully protected
in relying upon, any Letter of Credit, draft, writing, resolution, notice,
consent, certificate, affidavit, letter, cablegram, telegram, telecopy, telex or
teletype message, statement, order or other document believed by it to be
genuine and correct and to have been signed, sent or made by the proper Person
or Persons and upon advice and statements of legal counsel, independent
accountants and other experts selected by the Agent.  The Agent shall be fully
justified in failing or refusing to take any action requested by the Majority
Banks unless it shall first have




                                      -17-

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



     Section 3A.6.  LETTER OF CREDIT FEE.  The Borrower shall, on the date of
issuance or any extension or renewal of any Letter of Credit and at such other
time or times as such charges are customarily made by the Agent, pay a fee (in
each case, a "Letter of Credit Fee") to the Agent in respect of each Letter of
Credit equal to the Applicable Rate (as defined below) per annum of the face
amount of such Letter of Credit, PLUS the Agent's customary issuance fee.  For
the purposes of this Section 3A.6, "Applicable Rate" shall mean the percentage
rate per annum then in effect that the Borrower would pay with respect to
Eurodollar Rate Loans as the applicable margin over the Eurodollar Rate as set
forth in Section 2.5 of this Credit Agreement."

other sum is calculated by reference to the gross amount of any sum receivable
or deemed received by such Bank or the Agent from the Borrower hereunder,





                                      -21-

     then, and in each such case, the Borrower will, upon written demand made by
such Bank or (as the case may be) the Agent at any time and from time to time
and as often as the occasion therefor may arise, pay to such Bank or the Agent
such additional amounts as will be sufficient to compensate the Bank or the

enforcement of the claim evidenced by the Notes held by, or constituting
Reimbursement Obligations owed to, such Bank by proceedings against the Borrower
at law or in equity or by proof thereof in bankruptcy, reorganization,

Obligations, interest, fees or otherwise, to the remaining nondelinquent Banks
for application to, and reduction of, their respective PRO RATA shares of all
outstanding Loans and Unpaid Reimbursement Obligations.  The Delinquent Bank
hereby authorizes the Agent to distribute such payments to the nondelinquent
Banks in proportion to their respective PRO RATA shares of all outstanding Loans
and Unpaid Reimbursement Obligations.  A Delinquent Bank shall be deemed to have
satisfied in full a delinquency when and if, as a result of application of the
assigned payments to all outstanding Loans and Unpaid Reimbursement Obligations
of the nondelinquent Banks, the Banks' respective PRO RATA shares of all
outstanding Loans and Unpaid Reimbursement Obligations have returned to those in
