Section 2.03. Correction of Section 2.10 and 2.11 of the Loan Agreement.

For purposes of determining on or after the date hereof which Obligations outstanding constitute Existing Borrower Obligations, all payments received by Lender from any Existing Borrower on account of the Obligations shall be deemed to be applied first in payment of the Existing Borrower Obligations until such time as the Existing Borrower Obligations shall have been reduced to zero, and thereafter to the other Obligations as hereinafter set forth and unless Borrower indicates to the contrary in writing to Collateral Agent, all payments received by Collateral Agent through the Dominion Account shall be deemed to be payments received by Collateral Agent from Existing Borrowers.

On the date of the Second Amendment, the "Revolving Credit Loans" held by each Existing Lender shall automatically, and without any action on the part of any Person, be deemed to be respectively Revolving Credit Loans under this Agreement, and each of the Lenders shall, by assignments from each Existing Lender (which assignments shall be deemed to occur automatically, and without the requirement for additional documentation, on the date of the Second Amendment), acquire a percentage equal to the Total Commitment Percentage of each Lender of the "Revolving Credit Loans" of each Existing Lender outstanding immediately prior to the date of the Second Amendment, and each of the Lenders shall, through the Collateral Agent, make such other adjustments among themselves as shall be necessary, so that after giving effect to such assignments and adjustments, the Lenders shall hold hereunder Revolving Credit Loans (including Revolving Credit Loans outstanding immediately prior to the date of the Second Amendment) in an amount not greater than such Lender's Revolving Credit Commitment."

an Officer's Closing Certificate, executed by each Borrower, certifying that (a) the representations and warranties contained in the Loan Agreement and the Fourth Amendment are true and correct in all material respects on and as of the date hereof, (b) all conditions contained in the Loan Agreement required to be satisfied on or before the date of the Fourth Amendment have been complied with and presently are being complied with, and (c) no Default or Event of Default is currently in existence;

ARTICLE IV.
Limited Consent

Borrower has informed Collateral Agent and Lenders that MMI intends to enter into a lease agreement (the "Merrill Lynch Lease") and a security agreement (the "Merrill Lynch Security Agreement"), with Merrill Lynch Capital, A Division of Merrill Lynch Business Financial Services Inc. ("Merrill Lynch"), pursuant to which Merrill Lynch will lease to MMI certain property. As security for the payment and performance of MMI under the Merrill Lynch Lease, MMI will grant to Merrill Lynch a security interest in real property, machinery and equipment located in Jacksonville, Florida (the "Merrill Lynch Lien") pursuant to the Merrill Lynch Security Agreement. Absent Collateral Agent's and Lenders' consent, the incurrence of the Indebtedness under the Merrill Lynch Lease (the "Merrill Lynch Indebtedness") would violate Section 9.2(C) of the Loan Agreement and the creation of the Merrill Lynch Lien would violate Section 9.2(G) of the Loan Agreement. Collateral Agent and Lenders hereby consent to the creation of the Merrill Lynch Lien; provided, that Collateral Agent shall have received fully executed copies of the following documents, each to be in form and substance satisfactory to Collateral Agent in its sole discretion: (a) the Merrill Lynch Lease, (b) the Merrill Lynch Security Agreement, (c) a subordination agreement by and between Merrill Lynch and Collateral Agent, (d) a mortgagee/beneficiary waiver, duly executed and notarized by Merrill Lynch, and (e) all other agreements, documents or instruments executed in connection with any of the foregoing documents or otherwise required by Collateral Agent. Furthermore, the undersigned hereby waive Borrower's compliance with any provision of the Loan Agreement or any other Loan Document, which, if enforced, would prohibit the incurrence of the Merrill Lynch Indebtedness and the creation of the Merrill Lynch Lien or constitute a Default or an Event of Default under the Loan Agreement or any other Loan Document solely as a result of the incurrence of the Merrill Lynch Indebtedness and the creation of the Merrill Lynch Lien. Except as specifically set forth above, nothing contained herein shall be construed as a waiver by Collateral Agent or Lenders of any covenant or provision of the Loan Agreement, the Other Agreements, this Amendment, or of any other contract or instrument among Borrowers, Collateral Agent and/or Lenders, and the failure of Collateral Agent or Lenders at any time or times hereafter to require strict performance by Borrowers of any provision thereof shall not waive, affect or diminish any right of Collateral Agent or Lenders to thereafter demand strict compliance therewith. Collateral Agent and Lenders hereby reserve all rights granted under the Loan Agreement, the Other Agreements, this Amendment and any other contract or instrument among Borrowers, Collateral Agent and Lenders.

ARTICLE V.
