SECTION 4.           REPRESENTATIONS, WARRANTIES AND COVENANTS

Borrower and each of the other Credit Parties hereby further represent, warrant,
and covenant with and to Agent and the Lenders as follows:

4.1                  Representations and Warranties. After giving effect to this
Amendment, each of the representations and warranties made by or on behalf of
the Credit Parties to Agent and the Lenders in all of the Loan Documents was
true and correct in all material respects when made and is true and correct in
all material respects on and as of the date of this Amendment with the same full
force and effect as if each of such representations and warranties had been made
by such Person on the date hereof and in this Amendment, except to the extent
that such representation and warranty expressly relates to an earlier date and
except for changes therein expressly permitted or expressly contemplated by the
Credit Agreement.

4.2                  Binding Effect of Documents. This Amendment and the other
Loan Documents have been duly executed and delivered to Agent and the Lenders by
the Borrower and each of the other Credit Parties and are in full force and
effect, as modified hereby.

4.3                  No Conflict, Etc. The execution and delivery and
performance of this Amendment by the Borrower and each of the other Credit
Parties will not violate any federal, state or any other material law, rule,
regulation or order or material contractual obligation of such Person in any
material respect and will not result in, or require, the creation or imposition
of any Lien (other than the Liens created by the Collateral Documents) on any of
its Properties or revenues.

4.4                  Events of Default. No Events of Default, other than the
Specified Event of Default, as waived in Section 6 of this Amendment, are
continuing as of the date hereof. The parties hereto acknowledge, confirm, and
agree that any material misrepresentation by any Credit Party or any failure of
any Credit Party to comply with the covenants, conditions and agreements
contained in this Amendment shall constitute an Event of Default under the
Credit Agreement.

to each of the following conditions precedent having been satisfied as
determined in Agent’s sole discretion prior to the Fifth Amendment Closing Date:

the conditions to effectiveness specified in Section 5 above, the Agent and the

all parties hereto as of the date hereof. In the event of any conflict between
the terms of this Amendment and the other Loan Documents, the terms of this

continuity of Agent’s security interests in, security titles to or other Liens
on any Collateral for the Obligations. The Credit Agreement and this Amendment

preparation, negotiation, execution, or delivery of this Amendment and any
agreements delivered in connection herewith and expenses which shall at any time
be incurred or sustained by Agent or any participant of Agent or any of its
respective directors, officers, employees or agents as a consequence of or in
any way in connection with the preparation, negotiation, execution, or delivery
of this Amendment and any agreements prepared, negotiated, executed or delivered
in connection herewith.

7.4                  Further Assurances. The parties hereto shall execute and
deliver such additional documents and take such additional action as may be
necessary or desirable to effectuate the provisions and purposes of this
Amendment.

7.5                  Binding Effect. This Amendment shall be binding upon and
inure to the benefit of each of the parties hereto and their respective
successors and assigns.

7.6                  Survival of Representations and Warranties. All
representations and warranties made in this Amendment or any other document
furnished in connection with this Amendment shall survive the execution and
delivery of this Amendment and the other documents, and no investigation by
Agent or any Lender shall affect the representations and warranties or the right
of Agent or the Lenders to rely upon them.

7.7                  Releases by Credit Parties. As a material inducement to
Agent and the Lenders to enter into this Amendment and to grant concessions to
the Credit Parties, all in accordance with and subject to the terms and
conditions of this Amendment, each Credit Party:

discharge Agent and the Lenders and their subsidiaries and affiliates, and all
of their respective past, present and future officers, directors, employees,
agents, attorneys, representatives, participants, heirs, successors and assigns
(each a “Releasee” and collectively, the “Releasees”) from any and all manner of
debts, accountings, bonds, warranties, representations, covenants, promises,
contracts, controversies, arguments, liabilities, obligations, expenses,
damages, judgments, executions, actions, claims, demands and causes of action of
any nature whatsoever, whether at law or in equity, either now accrued or
hereafter maturing or whether known or unknown, which any Credit Party now has
or hereafter can, shall or may have by reason of any manner, cause or things,
from the beginning of the world to and including the date of this Amendment,
with respect to matters arising out of, in connection with or related to:

-4-

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

(i)                   any and all obligations owed or owing to any Releasee
under any document evidencing financial arrangements by, among and between such
Releasee and any Credit Party, relating to the Credit Agreement, and including,
but not limited to, the administration or funding thereof;

(ii)                   the Credit Agreement and indebtedness evidenced and
secured thereby; or

(iii)                   any other agreement or transaction between any Credit
Party and any Releasee entered into in connection with the Credit Agreement.

(b)                   Does hereby covenant and agree never to institute or cause
to be instituted or continued prosecution of any suit or other form of action or
proceeding of any kind or nature whatsoever against any Releasee by reason of or
in connection with any of the foregoing matters, claims or causes of action;
provided, however, that the foregoing release and covenant not to sue shall not
apply to any claim arising after the date of this Amendment with respect to
acts, occurrences or events after the date of this Amendment; and, further
provided that the foregoing release and covenant not to sue shall not apply to
any rights or claims, if any, of any third party creditors of any Credit Party.
If any Credit Party or any of its successors, assigns or other legal
representations violates the foregoing covenant, such Credit Party and its
successors, assigns and legal representatives, jointly and severally agree to
pay, in addition to such other damages as any Releasee may sustain as a result
of such violation, all attorneys’ fees and costs incurred by any Releasee as a
result of such violation.

(c)                   Does hereby expressly acknowledge and agree that the
covenants and agreements of Agent and the Lenders contained in this Amendment
shall not be construed as an admission of any wrongdoing, liability or
culpability on the part of Agent or any Lender or as any admission by Agent or
any Lender of the existence of claims by any Credit Party against Agent, the
Lenders or any other Releasee. Each Credit Party, Agent and the Lenders
acknowledge and agree that the value to the Credit Parties of the covenants,
consents and agreements on the part of Agent and the Lenders contained in this
Amendment substantially and materially exceed any and all value of any kind or
nature whatsoever of any claims or other liabilities waived or released by the
Credit Parties.

(d)                   Notwithstanding anything contained in this Amendment, the
general release set forth in this Amendment shall not extend to and shall not
include any duties or obligations of Agent or the Lenders in the Credit
Agreement as modified by this Amendment or in any of the Loan Documents.

7.8                   Entire Agreement. This Amendment expresses the entire
understanding and agreement of the parties hereto with respect to the subject
matter hereof and supersedes all prior understandings, negotiations,
correspondence and agreements of the parties regarding such subject matter.

7.9                   GOVERNING LAW. THE LAWS OF THE STATE OF NEW YORK SHALL
GOVERN ALL MATTERS ARISING OUT OF, IN CONNECTION WITH OR RELATING TO THIS
AMENDMENT, INCLUDING, ITS VALIDITY, INTERPRETATION, CONSTRUCTION, PERFORMANCE
AND ENFORCEMENT (INCLUDING, ANY CLAIMS SOUNDING IN CONTRACT OR TORT LAW ARISING
OUT OF THE SUBJECT MATTER HEREOF AND ANY DETERMINATIONS WITH RESPECT TO
POST-JUDGMENT INTEREST).

reference to the same extent as if reproduced herein in their entirety.

number of counterparts, each of which when so executed shall be deemed to be an
original and all of which taken together shall constitute one and the same
agreement. Signature pages may be detached from multiple separate counterparts
