WHEREAS, the Borrower has requested and the Administrative Agent and Lenders have agreed to amend certain terms of the Credit Agreement as set forth herein;

NOW, THEREFORE, IN CONSIDERATION of the premises and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto agree as follows:

1. Amendment. The Credit Agreement is hereby amended:

(a) by adding a new Section 1.6 to the Credit Agreement to provide as follows:

1.6 Increase in Revolver Commitments.

(a) So long as no Default or Event of Default exists, the Borrower may request that the Commitments be increased and, upon such request, the Administrative Agent shall have the right to solicit additional financial institutions to become Lenders for purposes of this Agreement (“New Lenders”), or to encourage any Lender to increase its Commitment, provided that (i) each Lender which is a party to this Agreement prior to such increase shall have the first option, and may elect, to fund an amount up to its Pro Rata Share of the amount of the increase in the Commitment (or any such greater amount in the event that one or more Lenders does not elect to fund its respective Pro Rata Share of the amount of the increase in the Revolver Commitment), thereby increasing its Commitment hereunder, but no Lender shall have any obligation to do so, (ii) in the event that it becomes necessary to include New Lenders to fund the amount of the increase in the Commitment, each such New Lender shall be acceptable to the Administrative Agent and the Borrower (neither of whose acceptance shall be unreasonably withheld) and each such New Lender shall become a Lender hereunder and agree to become party to, and shall assume and agree to be bound by, this Agreement, subject to all terms and conditions hereof; (iii) the Administrative Agent shall have no

obligation to the Borrower or to any Lender to solicit New Lenders or any increase in the Commitment of any Lender pursuant to this Section 1.6; (iv) no Lender shall have an obligation to the Borrower, the Administrative Agent or any other Lender to increase its Commitment or its Pro Rata Share of the Commitments; and (v) in no event shall the addition of any New Lender or Lenders or the increase in the Commitment of any Lender under this Section 1.6 increase the Commitments to an amount greater than $140,000,000 in the aggregate. Upon the addition of any New Lender, or the increase in the Commitment of any Lender, Schedule 1.2 shall be amended by the Administrative Agent and the Borrower to reflect such New Lenders or such increase, and the Administrative Agent shall deliver to the Lenders, and the Bank copies of such Schedule 1.2, any New Lender pursuant to this Section 1.6 shall be required to have a Commitment of not less than $10,000,000.

(b) If any requested increase in the Commitments is agreed to in accordance with Section 1.6(a)(i) above, the Administrative Agent and the Borrower shall determine the effective date of such increase (the “Increase Effective Date”). The Administrative Agent, with the consent and approval of the Borrower, shall promptly confirm in writing to the Lenders the final allocation of such increase and the Increase Effective Date and, each New Lender, and each existing Lender that has elected to increase its Commitment, shall purchase Revolving Loans and participations in outstanding Letters of Credit from each other Lender in an amount such that, after such purchase or purchases, the amount of outstanding Revolver Loans and such Letters of Credit from each Lender shall equal such Lender’s respective Pro Rata Share of the Commitments, as modified to give effect to such increase, multiplied by the aggregate amount of Revolver Loans outstanding and Letters of Credit outstanding from all Lenders. As a condition precedent to the effectiveness of such increase, the Borrower shall deliver to the Administrative Agent a certificate dated as of the Increase Effective Date (in sufficient copies for each Lender) signed by a responsible officer of the Borrower, including a certificate demonstrating compliance with the terms of this Agreement and certification that, before and after giving effect to such increase, the representations and warranties contained in Article 6 are true and correct in all material respects on and as of the Increase Effective Date (except to the extent any such representation or warranty is stated to relate solely to an earlier date) and no Default or Event of Default exists. Upon the request of any Lender, the Borrower shall deliver a new or amended Revolving Loan Note reflecting the new or increased Commitment of each New Lender or any other affected Lender, as the case may be, as of the Increase Effective Date. The Borrower shall prepay any Revolving Loans which are LIBOR Loans and which are outstanding on the Increase Effective Date (and pay any costs incurred in connection with such prepayment pursuant to Section 4.4) to the extent necessary to keep the outstanding Revolving Loans ratable with any revised Pro Rata Shares of the Commitments arising from any nonratable increase in the Commitments.

(c) Notwithstanding the foregoing provisions of this Section 1.6, the Borrower shall not be entitled increase the amount of the Commitments hereunder if it previously elected to voluntarily reduce the Commitments pursuant to Section 1.2(a)(iv).

(d) If one or more New Lender or any other Lender fund an increase in the Commitments pursuant to the foregoing provisions of this Section 1.6 (such Lenders being hereafter referred to as “Commitment Increase Lenders”) and other Lenders elect not to fund any such increase in the Commitments, and thereafter the Borrower elects to voluntarily reduce the Commitments pursuant to Section 1.2(a)(iv), any such reduction in the Commitments shall be allocated, on a pro rata basis, first to such Commitment Increase Lenders to the extent of their new or increased Commitments under this Section 1.6, and thereafter, on a pro rata basis as provided in Section 1.2(a)(iv), to the other Lenders who are not Commitment Increase Lenders.

The Unused Line Fee shall be computed on the basis of a 360-day year for the actual number of days elapsed.
