               (e) Prepayment Premium. In the event that Borrowers shall
voluntarily prepay Term Loan A, Term Loan B, the Protective Overadvances or all
three, Borrowers shall pay a prepayment premium in an amount equal to 1% of the

discretion, may extend, and hereby is authorized to extend, the Maturity Date
for a period of up to an additional 30 days without further action by the
Lenders so long as the following conditions are satisfied (or waived by) the
Term Loan B Agent in its sole discretion:

               (i) Borrowers shall have filed a Section 1113(e) motion with the

Revolving Loans (the "Additional Financing") on or before May 18, 2006; and

                    (iii) Borrowers shall have made reasonably satisfactory
progress, as determined by the Term Loan B Agent in its sole discretion, in

               (g) Notwithstanding any other provision hereof, it is understood

               (e) Section 9.2 Appointment of Agents of the Credit Agreement is
hereby amended as of the Amendment Effective Date by deleting the third and
fourth sentences of such Section 9.2 in their entirety and substituting in lieu
thereof the following new sentences:

          "Morgan Stanley is hereby appointed to act on behalf of all Term Loan
          A Lenders as 'Term Loan A Agent' under this Agreement and the other
          Loan Documents. Morgan Stanley is hereby appointed to act on behalf of

          exercise the same as though it were not an Agent; and the term
          "Lender" or "Lenders" shall, unless otherwise expressly indicated,
          include each of GE Capital and Morgan Stanley in its individual
          capacity. Each of GE Capital and Morgan Stanley and its respective
          Affiliates may lend money to, invest in, and generally engage in any
          kind of business with, any Credit Party, any of their Affiliates and
          any Person who may do business with or own securities of any Credit
          Party or any such Affiliate, all as if GE Capital and Morgan Stanley
          were not an Agent and without any duty to account therefor to Lenders.
          Each of GE Capital and Morgan Stanley and its respective Affiliates
          may accept fees and other consideration from any Credit Party for
          services in connection with this Agreement or otherwise without having
          to account for the same to Lenders. Each Lender acknowledges the
          potential conflict of interest between GE Capital and Morgan Stanley
          as Lenders holding disproportionate interests in the Loans and GE
          Capital and Morgan Stanley as Agents."

               (g) Section 11.2 Amendments and Waivers of the Credit Agreement
is hereby amended as of the Amendment Effective Date by adding the following at
the end of Section 11.2 as new clause (f):

          "(f) The Lenders hereby irrevocably authorize the Collateral Agent,
          without further action of the Lenders, to release any Lien on any
          Collateral constituting property being sold or disposed of if a
          release is required or desirable in connection therewith and if
          Borrowers certify in writing to the Collateral Agent that the sale or
          disposition is permitted or not otherwise prohibited under this
          Agreement or the other Loan Documents (and the Collateral Agent may
          rely conclusively on any such certificate, without further inquiry).
          Except as provided above


                                       -6-

<PAGE>

          or expressly provided in any other Loan Document, the Collateral Agent
          will not execute and deliver a release of any Lien on any Collateral
          without the prior written authorization of all of the Lenders. Upon
          request by the Collateral Agent or Borrowers at any time, the
          Administrative Agent and the Lenders will confirm in writing the
          Collateral Agent's authority to release any such Liens on particular
          types or items of Collateral pursuant to this Section 11.2; provided,
          however, that (1) the Collateral Agent shall not be required to
          execute any document necessary to evidence such release on terms that,
          in the Collateral Agent's opinion, would expose the Collateral Agent
          to liability or create any obligation or entail any consequence other
          than the release of such Lien without recourse, representation, or
          warranty, and (2) such release shall not in any manner discharge,
          affect, or impair the Obligations or any Liens (other than those
          expressly being released) upon (or obligations of Borrowers in respect
          of) all interests retained by Borrowers, including, the proceeds of
          any sale, all of which shall continue to constitute part of the
          Collateral."

               (h) Section 11.14 Press Releases and Related Matters of the
Credit Agreement is hereby amended as of the Amendment Effective Date by
deleting it in its entirety and substituting in lieu thereof the following:

          "Each Credit Party executing this Agreement agrees that neither it nor
          its Affiliates will in the future issue any press releases or other
          public disclosure using the name of Morgan Stanley or GE Capital or
          any of their affiliates or referring to this Agreement, the other Loan
          Documents or the Related Transactions Documents without at least two
          (2) Business Days' prior notice to Morgan Stanley or GE Capital and
          without the prior written consent of Morgan Stanley or GE Capital, as
          applicable, unless (and only to the extent that) such Credit Party or
          Affiliate is required to do so under law and then, in any event, such
          Credit Party or Affiliate will consult with Morgan Stanley or GE
          Capital, as applicable, before issuing such press release or other
          public disclosure. Each Credit Party consents to the publication by
          any Agent or any Lender of advertising material relating to the
          financing transactions contemplated by this Agreement using Borrower's
          name, product photographs, logo or trademark. Agents reserve the right
          to provide to industry trade organizations information necessary and
          customary for inclusion in league table measurements."

               (i) Annex A of the Credit Agreement is hereby amended as of the
Amendment Effective Date by deleting the definition of "EBITDA" in its entirety
and substituting in lieu thereof the following new definition:


                                       -7-

          all inventory sold in conjunction with the disposition of fixed assets
          and all securities), in each case to the extent included in the

          write-up of any asset; (6) any net gain from the collection of the
          proceeds of life insurance policies; (7) any net gain arising from the
          acquisition of any securities, or the extinguishment, under GAAP, of
          any Indebtedness, of such Person; (8) in the case of a successor to

          "'Term Loan A Agent' means Morgan Stanley, in its capacity as agent

          6. Forbearance. Notwithstanding the existence of the Specified Events
of Default, the Administrative Agent and the Lenders agree to extend the
Forbearance for the Specified Events of Default on the terms and conditions set
forth in the Forbearance Extension until the Maturity Date, as such Maturity
Date may be extended by the Term Loan B Agent without further action of the
Lenders as provided for in Section 3(f) hereof.

          7. Reservation of Rights. You are hereby advised that the
Administrative Agent and the Lenders specifically reserve all of their rights
and remedies against Borrowers under the Loan Documents and applicable law with
respect to the Specified Events of Default. Neither the Administrative Agent nor
any Lender shall be deemed to have waived any term or condition of the Credit
Agreement or any other Loan Document or, except as specifically set forth
herein, to have agreed to a forbearance with respect to any right or remedy
which the Administrative Agent or the Lenders may now have or in the future may
have under the Credit Agreement or any other Loan Document, at law, in equity or
otherwise, on account of the Specified Events of Default or any other Default or
Event of Default. Neither the Administrative Agent nor any Lender shall by
virtue of any action or omission be deemed to have altered or prejudiced any
rights or remedies under or in connection with the Credit Agreement or under or
in connection with any Event of Default. All of the terms and conditions of the
Credit Agreement and the other Loan Documents are and shall remain in full force
and effect.

          8. Representations and Warranties. To induce the Requisite Lenders to
enter into this Amendment, each of the Credit Parties executing this Amendment,
jointly and severally, makes the following representations and warranties:

               (a) Subject to the approval of the Bankruptcy Court, the
execution, delivery and performance by such Credit Party of this Amendment: (i)
are within such Credit Party's power; (ii) have been duly authorized by all
necessary corporate, limited liability company or limited partnership action;
(iii) do not contravene any provision of such Credit Party's charter, bylaws or
partnership or operating agreement as applicable; (iv) do not violate any law or
regulation, or any order or decree of any court or Governmental Authority; (v)
do not conflict with or result in the breach or termination of, constitute a
default under or accelerate or permit the acceleration of any performance
required by, any indenture, mortgage, deed of trust, lease, agreement or other
instrument to which such Credit Party is a party or by which such Credit Party
or any of its property is bound; (vi) do not result in the creation or
imposition of any Lien upon any of the property of such Credit Party; and (vii)
do not require the consent or approval of any Governmental Authority or any
other Person other than the Bankruptcy Court.

               (b) This Amendment has been duly executed and delivered by or on
behalf of such Credit Party.

               (c) Subject to the approval of the Bankruptcy Court, each of this
Amendment and the Credit Agreement constitutes a legal, valid and binding
obligation of such Credit Party, enforceable against it in accordance with its
terms, except as such enforceability may be limited by applicable bankruptcy,
insolvency, reorganization, moratorium or other laws relative to or affecting
the enforcement of creditors' rights generally in effect from time to time and
by general principles of equity.

               (d) No Default or Event of Default has occurred and is continuing
after giving effect to this Amendment, except for the Defaults or Events of
Default set forth on Schedule A hereto.

               (e) Other than the commencement of the Chapter 11 Cases, no
action, claim, lawsuit, demand, investigation or proceeding is now pending or,
to the knowledge of such Credit Party, threatened against such Credit Party,
before any Governmental Authority or before any arbitrator or panel of
arbitrators, (i) that challenges such Credit Party's right or power to enter
into or perform any of its obligations under this Amendment or the other Loan
Documents to which it is a party, or the validity or enforceability of any Loan
Document or any action taken thereunder, or (ii) that has a reasonable risk of
being determined adversely to any Credit Party and that, if so determined, would
reasonably be expected to have a Material Adverse Effect.

               (f) The representations and warranties of such Credit Party
contained in the Credit Agreement and each other Loan Document, as amended in
accordance with the terms of the applicable agreement, shall be true and correct
on and as of the Amendment Effective Date with the same effect as if such
representations and warranties had been made on and as of such date, except that
any such representation or warranty which is expressly made only as of a
specified date need be true only as of such date.

          9. No Other Consents/Waivers. Except as expressly provided herein, (a)
the Credit Agreement shall be unmodified and shall continue to be in full force
and effect in accordance with its terms, (b) this Consent shall not be deemed a
waiver of any term or condition of the Credit Agreement or any other Loan
Document, and (iii) this Consent shall not be deemed an agreement to forbear
with respect to any right or remedy which the Agents or the Lenders may now have
or may have in the future under the Credit Agreement or any other Loan Document,
at law, in equity or otherwise. For avoidance of doubt, the Financial Covenants
set forth in Annex G to the Credit Agreement for all periods commencing on June
30, 2006 shall be unmodified and shall continue to be in full force and effect
in accordance with the terms of the Credit Agreement. Neither any Agent nor any
Lender shall by virtue of any action or omission be deemed to have altered or
prejudiced any rights or remedies which any Agent or any Lender may now have or
may have in the future under or in connection with the Credit Agreement, any
other Loan Document or any of the instruments or agreements referred to therein,
in each case as the same may be amended from time to time.

releases, remises and forever discharges Agents, the Lenders and each other
Indemnified Person from any and all claims, suits, actions, investigations,
proceedings or demands arising out of or in connection with the Credit Agreement
(collectively, "Claims"), whether based in contract, tort, implied or express
warranty, strict liability, criminal or civil statute or common law of any kind
or character, known or unknown, which such Credit Parties ever had, now has or
might hereafter have against Agents or the Lenders which relates, directly or
indirectly, to any acts or omissions of Agents, the Lenders or any other
Indemnified Person on or prior to the date hereof; provided that, Credit Parties
do not waive

any Claim solely to the extent such Claim relates to any Agent's or any Lender's
gross negligence or willful misconduct.

warranties of or on behalf of the Credit Parties in this Amendment shall be true
