WHEREAS, the Administrative Agent, Documentation Agent and Lenders are willing to so amend such provisions of the Agreement in accordance with the terms and conditions hereof.

NOW, THEREFORE, in consideration of the foregoing, and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Incorporation of Defined Terms. Each capitalized term used in this Amendment but not otherwise defined herein shall have the meaning ascribed thereto in the Agreement.

2. Definitional Amendments.

(A) The definitions of “Revolving Commitment”, “Tangible Net Worth” and “Termination Date” that appear in the Agreement shall be deleted in their entirety and replaced with the following (for the sake of clarity, “Tangible Net Worth” shall be replaced by “Consolidated Net Worth”):

Consolidated Net Worth means, with respect to the Company and its Subsidiaries, consolidated assets less consolidated liabilities, all as determined pursuant to GAAP applied on a basis consistent with the financial statements defined pursuant to Section 10.1.1 and Section 10.1.2.

Revolving Commitment means $200,000,000 plus the Incremental Commitment, if any, as reduced from time to time pursuant to Section 6.1.

Termination Date means the earlier to occur of (a) December 19, 2010 or (b) such other date on which the Commitments terminate pursuant to this Agreement. The Company may, upon written request delivered to the Administrative Agent not later than ninety (90) days prior to December 19, 2010, and provided that no Event of Default or Unmatured Event of Default then exists, request the Lenders to extend the Termination Date for one (1) additional year, subject to the approval of the Lenders as set forth in Section 15.1 hereof. The Administrative Agent shall provide written notice of the decision of the Lenders to the Company within thirty (30) days of receipt of the Company’s request therefor. In the event Administrative Agent fails to provide such written notice to the Company, the Company’s request shall be deemed to be denied. Notwithstanding anything to the contrary herein, in the event the Company has not delivered to Administrative Agent before November 15, 2005, evidence satisfactory to Administrative Agent of the Company’s successful completion of an equity and/or subordinated debt offering in an amount not less than $50,000,000 (the “Equity Offering”), the Termination Date shall be December 19, 2006 and shall not be eligible for extension pursuant to this definition.

(B) The following paragraph shall be added to the end of the definition of Applicable Margin

Notwithstanding anything to the contrary in this definition, beginning with the first day of the first Fiscal Quarter of the Company commencing after the successful completion (such date to be no later than November 15, 2005) of the Equity Offering, the above grid shall be replaced with the following:

2

(C) The reference to “one, two, three or six months” in the definition of “Interest Period” as appears in the Credit Agreement shall be replaced with “7 days, 14 days or one, two, three, six or nine months”.

(B) The reference to “66 ²/3%” in the definition of “Required Lenders” in Section 1.1 of the Agreement shall be replaced with “51%”.

(C) Section 2.1.2 of the Agreement shall be amended by replacing the amount of $60,000,000 in clause (a) of the proviso thereto with the amount of $100,000,000.

(D) Section 2.1.3 of the Agreement shall be deleted in its entirety and replaced with the following:

The Company may, at times prior to the Termination Date, by written notice to the Administrative Agent, request an increase in the Revolving Commitment (an “Incremental Commitment”) in an amount not less than $1,000,000 and not to exceed such amount as would cause the Revolving Commitment to exceed $250,000,000 from one or more Lenders (which may include any existing Lender); provided, that any new Lender shall be subject to the approval of the Administrative Agent. Such notice shall set forth the amount of the Incremental Commitment (which shall be in minimum increments of $1,000,000) and the date on which such Incremental Commitment is requested to become effective (which shall not be less than 10 Business Days nor more than thirty (30) Business Days after the date of such notice). Upon receipt of such notice, the Administrative Agent shall use its best efforts to identify additional Lenders so as to increase the Revolving Commitment by the Incremental Commitment. In the event Administrative Agent is successful, the Company and the Lender(s) providing the Incremental Commitment shall execute and deliver to the Administrative Agent such documentation as the Administrative Agent shall reasonably specify to evidence the Incremental Commitment, including, without limitation, (if applicable) an agreement pursuant to which any new Lender shall agree to be bound by the terms of this Agreement and the other Loan Documents. Each of the parties hereto agrees that, upon acceptance of such documents and approval of the Incremental Commitment by the Administrative
