               description prepared by the Parent and provided to the
               Administrative Agent on or about October 23, 2003 and shall

     3.   CONDITIONS TO EFFECTIVENESS. This Amendment shall become effective
when the Administrative Agent shall have received a counterpart signature page
to this Amendment duly executed and delivered by each of the Borrowers and the
Required Lenders.

     4.   REPRESENTATIONS AND WARRANTIES. Each of the Borrowers represents and
warrants to the Lenders and the Administrative Agent as follows:

               (a)  The execution, delivery and performance of each of this
     Amendment and the transactions contemplated hereby and thereby are within
     the corporate or equivalent company power and authority of such Borrower
     and have been or will be authorized by proper corporate or equivalent
     company proceedings, and do not (i) require any consent or approval of the
     equity holders of such Borrower which has not been obtained, (ii)
     contravene any provision of the constituent documents of such Borrower or
     any law, rule or regulation applicable to such Borrower, or (iii)
     contravene any provision of, or constitute an event of default or event
     which, but for the requirement that time elapse or notice be given, or
     both, would constitute an event of default under, any other material
     agreement, instrument or undertaking binding on such Borrower.

               (b)  This Amendment and all of the terms and provisions hereof
     and thereof are the legal, valid and binding obligations of such Borrower
     enforceable in accordance with their respective terms except as limited by
     bankruptcy, insolvency, reorganization, moratorium or other laws affecting
     the enforcement of creditors' rights generally, and except as the remedy of
     specific performance or of injunctive relief is subject to the discretion
     of the court before which any proceeding therefor may be brought.

               (c)  The execution, delivery and performance of this Amendment
     does not require any approval or consent of, or filing or registration
     with, any governmental or other agency or authority, or any other party.

               (d)  The representations and warranties contained in Section 6 of
     the Credit Agreement are true and correct in all material respects as of
     the date hereof as though made on and as of the date hereof (except to the
     extent of changes resulting from transactions contemplated or permitted by
     the Credit Agreement as amended by this Amendment and changes occurring in
     the ordinary course of business which singly or in the aggregate are not
     materially adverse, and to the extent that such representations and
     warranties relate expressly to an earlier date).

               (e)  After giving effect to this Amendment, no Default or Event
     of Default under the Credit Agreement will occur or be continuing.

                                      - 9 -

     5.   RATIFICATION, ETC. Except as expressly amended hereby, the Credit
Agreement, the other Loan Documents and all documents, instruments and
agreements related thereto are hereby ratified and confirmed in all respects and
shall continue in full force and effect. This Amendment and the Credit Agreement
shall hereafter be read and construed together as a single document, and all
references in the Credit Agreement or any related agreement or instrument to the
Credit Agreement shall hereafter refer to the Credit Agreement as amended by
this Amendment.

     6.   NO IMPLIED WAIVER. Except as expressly set forth in this Amendment,
this Amendment shall not, by implication or otherwise, limit, impair, constitute
a waiver of or otherwise affect any rights or remedies of the Administrative
Agent or the Lenders under the Credit Agreement or the other Loan Documents, nor
alter, modify, amend or in any way affect any of the terms, obligations or
covenants contained in the Credit Agreement or the Loan Documents, all of which
shall continue in full force and effect. Nothing in this Amendment shall be
construed to imply any willingness on the part of the Administrative Agent or
the Lenders to grant any similar or future consent or waiver of any of the terms
and conditions of the Credit Agreement or the other Loan Documents.

     7.   COUNTERPARTS; GOVERNING LAW. This Amendment may be executed in any
number of counterparts and by different parties hereto on separate counterparts,
each of such when so executed and delivered shall be an original, but all of
such counterparts shall together constitute but one and the same agreement. THIS
CONSENT SHALL BE GOVERNED BY AND INTERPRETED AND DETERMINED AS AN INSTRUMENT
UNDER SEAL IN ACCORDANCE WITH THE LAWS OF THE COMMONWEALTH OF MASSACHUSETTS,
WITHOUT REFERENCE TO CONFLICTS OF LAW. This Amendment, to the extent signed and
delivered by means of a facsimile machine or other electronic transmission in
which the actual signature is evident, shall be treated in all manner and
respects as an original agreement or instrument and shall be considered to have
the same binding legal effect as if it were the original signed version thereof
delivered in person. At the request of any party hereto, each other party hereto
or thereto shall re-execute original forms hereof and deliver them to all other
parties. No party hereto shall raise the use of a facsimile machine or other
electronic transmission in which the actual signature is evident to deliver a
signature or the fact that any signature or agreement or instrument was
transmitted or communicated through the use of a facsimile machine or other
electronic transmission in which the actual signature is evident as a defense to
the formation of a contract and each party forever waives such defense.

     8.   DOLLAR AMOUNTS. All dollar amounts set forth herein which are payable
in the future are reflected in this amendment on a present discounted value
basis (calculated in accordance with GAAP).

     IN WITNESS WHEREOF, each of the undersigned have duly executed this
Amendment under seal as of the date first set forth above.
