Default or Event of Default under the Credit Agreement or any of the Loan
Documents.

            5. Representations and Warranties of the Borrowers. Each of the
Borrowers hereby represents and warrants to the Lender, which representations
and warranties shall survive the execution and delivery of this Amendment, that
on and as of the date hereof and after giving effect to this Amendment:

               (a) As to each Borrower, the execution, delivery, and performance
            by such Borrower of this Amendment have been duly authorized by all

            by such Borrower of this Amendment does not and will not (i) violate
            any provision of federal, state, or local law or regulation
            applicable to any Borrower, the Governing Documents of any Borrower,

               (c) As to each Borrower, this Amendment and all other documents
            contemplated hereby, when executed and delivered by such Borrower
            will be the legally valid and binding obligations of such Borrower,
            enforceable against such Borrower in accordance with their
            respective terms, except as enforcement may be limited by equitable
            principles or by bankruptcy, insolvency, reorganization, moratorium,
            or similar laws relating to or limiting creditors' rights generally.

               (d) The representations and warranties of each of the Borrowers
            set forth in the Credit Agreement and in the Loan Documents to which
            it is a party are true, correct and complete on and as of the date
            hereof; provided, that the references to the Credit Agreement
            therein shall be deemed to include the Credit Agreement as amended
            by this Amendment.

               (e) Each of the Borrowers acknowledges that the Lender is
            specifically relying upon the representations, warranties and
            agreements contained in this Amendment and that such
            representations, warranties and agreements constitute a material
            inducement to the Lender in entering into this Amendment.

            6. Release by the Borrowers. In further consideration of the
Lender's execution of this Amendment, each of the Borrowers hereby waives any
defense, right of set-off or claim against Lender and any of its affiliates,
directors, officers, employees, agents and representatives existing as of the
date hereof with respect to the Credit Agreement and the Loan Documents and each
of the Borrowers hereby forever remises, releases, acquits, satisfies and
forever discharges the Lender and each of its successors, assigns, affiliates,
officers, employees, directors, agents and attorneys (collectively, the
"RELEASEES") from any and all claims, demands, liabilities, disputes, damages,
suits, controversies, penalties, fees, losses, costs, expenses, reasonable
attorneys' fees, actions and causes of action (whether at law or in equity) and
obligations of every nature whatsoever, whether liquidated or unliquidated,
known or unknown, matured or unmatured, fixed or contingent, that any Borrower
ever had, now has, or may have against or seek from any or all of the Releasees
that arise from or relate to any actions that any or all of the Releasees may
have taken or omitted to take prior to the date this Amendment was executed (or
otherwise), including, without limitation, with respect to the Obligations, any
Collateral, the Credit Agreement and any of the Loan Documents, other than for
the Lender's gross negligence or willful misconduct.

            7. Reference to Credit Agreement; No Waiver.

            7.1 Upon the effectiveness of this Amendment, each reference in the
Credit Agreement to "this Credit Agreement," "hereunder," "hereof," "herein" or
words of like import shall mean and be a reference to the Credit Agreement as
amended hereby. The term "Loan Documents" as defined in Schedule 1.1 of the
Credit Agreement shall include (in addition to the Loan Documents described in
the Credit Agreement) this Amendment and any other agreements, instruments or
other documents executed in connection herewith.


                                       3

            7.2 The Lender's failure, at any time or times hereafter, to require
strict performance by the Borrowers of any provision or term of the Credit
Agreement, this Amendment or the other Loan Documents shall not waive, affect or
diminish any right of the Lender thereafter to demand strict compliance and
performance therewith. Any suspension or waiver by the Lender of a breach of
this Amendment or any Event of Default under the Credit Agreement shall not,
except as expressly set forth herein, suspend, waive or affect any other breach
of this Amendment or any Event of Default under the Credit Agreement, whether
the same is prior or subsequent thereto and whether of the same or of a
different kind or character. None of the undertakings, agreements, warranties,
covenants and representations of any Borrower contained in this Amendment, shall
be deemed to have been suspended or waived by the Lender unless such suspension
or waiver is: (i) in writing and signed by the Lender and (ii) delivered to the
Borrower. In no event shall the Lender's execution and delivery of this
Amendment establish a course of dealing among the Lender, the Borrowers, or any
other obligor or in any other way obligate the Lender to hereafter provide any
amendments or waivers with respect to the Credit Agreement. The terms and
provisions of this Amendment shall be limited precisely as written and shall not
be deemed: (A) to be a consent to a modification, amendment or waiver of any
other term or condition of the Credit Agreement or of any other Loan Documents,
or (B) to prejudice any right or remedy that the Lender may now have under or in
connection with the Credit Agreement or any of the other Loan Documents.

            8. Successors and Assigns; Amendment. This Amendment shall be
binding upon and inure to the benefit of the parties hereto and their respective
successors and assigns; provided, however, no Borrower may assign this Amendment
or any of its respective rights hereunder without the Lender's prior written
consent. Any prohibited assignment of this Amendment shall be absolutely null
and void. This Amendment may only be amended or modified by a writing signed by
the Lender and the Borrowers.

            9. Severability; Construction. Wherever possible, each provision of
this Amendment shall be interpreted in such a manner so as to be effective and
valid under applicable law, but if any provision of this Amendment is held to be
prohibited by or invalid under applicable law, such provision or provisions
shall be ineffective only to the extent of such provision and invalidity,
without invalidating the remainder of this Amendment. Neither this Amendment nor
any uncertainty or ambiguity herein shall be construed or resolved against
Lender, whether under any rule of construction or otherwise. On the contrary,
this Amendment has been reviewed by all parties hereto and shall be construed
and interpreted according to the ordinary meaning of the words used so as to
fairly accomplish the purposes and intentions of the parties hereto.

            10. Counterparts; Facsimile. This Amendment may be executed in one
or more counterparts, each of which taken together shall constitute one and the
same instrument. Delivery of an executed counterpart of this Amendment by
telefacsimile shall be equally as effective as delivery of a manually executed
counterpart of this Amendment. Any party delivering an executed counterpart of
this Amendment by telefacsimile shall also deliver a manually executed
counterpart of this Amendment, but the failure to deliver a manually executed
counterpart shall not affect the validity, enforceability or binding effect of
this Amendment.

         WITH THE LAWS OF THE STATE OF NEW YORK.

         CONNECTION WITH THIS AMENDMENT SHALL BE TRIED AND LITIGATED ONLY IN THE
         STATE AND FEDERAL COURTS LOCATED IN THE COUNTY OF NEW YORK, STATE OF
         NEW YORK, PROVIDED, HOWEVER, THAT ANY SUIT SEEKING ENFORCEMENT AGAINST
         ANY BORROWER COLLATERAL OR OTHER PROPERTY MAY BE BROUGHT, AT LENDER'S
         OPTION, IN THE COURTS OF ANY JURISDICTION WHERE AGENT ELECTS TO BRING
         SUCH ACTION OR WHERE SUCH BORROWERS COLLATERAL OR OTHER PROPERTY MAY BE
         FOUND. BORROWER AND THE LENDERS WAIVE, TO THE EXTENT PERMITTED UNDER
         APPLICABLE LAW, ANY RIGHT EACH MAY HAVE TO ASSERT THE DOCTRINE OF FORUM
