SECTION 3. Amendments to Credit Agreement.

(a) Subject to the satisfaction (or waiver in accordance with Section 4 hereof) of the conditions set forth in Section 4 hereof, the Incremental Revolving Facility Commitment shall be deemed to be an Existing Revolving Facility Commitment for all purposes under the Credit Agreement, and Exhibit A attached hereto shows (as of the First Incremental Effective Date) all Existing Revolving Facility Lenders and their respective corresponding Existing Revolving Facility Commitments.

(b) Subject to the satisfaction (or waiver in accordance with Section 4 hereof) of the conditions set forth in Section 4 hereof, the Credit Agreement is hereby amended as follows:

(i) Amendments to Section 1.01 (Defined Terms):

(A) Section 1.01 of the Credit Agreement is hereby amended by adding in the appropriate alphabetical order the following new definitions:

“First Incremental Amendment” shall mean the First Amendment to Amended and Restated Credit Agreement, dated as of March 21, 2012 among the Borrower, the Lenders party thereto and the Administrative Agent.

“First Incremental Amendment Effective Date” shall have the same meaning assigned to such term in the First Incremental Amendment.

(B) Section 1.01 of the Credit Agreement is hereby further amended by deleting the period at end of clause (h) of the definition of “Collateral and Guarantee Requirement” and replacing it with “; and” and by adding the following clause (i) immediately thereafter:

(i) subject to the Agreed Security Principles, within the applicable period of time set forth in Schedule 1.01(BC), or, in each case, such longer period as the Administrative Agent may agree in writing in its discretion (such agreement not to be unreasonably withheld or delayed), the Administrative Agent shall have received from each Loan Party all duly executed security agreements, pledge agreements, mortgages, amendment agreements, affirmations, documents and instruments set forth in Schedule 1.01(BC), together with such customary legal opinions (prepared by either the Borrower’s legal counsel or the Administrative Agent’s legal counsel as is customary for the relevant jurisdiction) as the Administrative Agent reasonably requests in connection therewith, in each case in form and substance reasonably satisfactory to the Administrative Agent.

(C) Section 1.01 of the Credit Agreement is hereby further amended by replacing the definition of “Existing Revolving Facility Commitment with the following:

“Existing Revolving Facility Commitment” shall mean, with respect to each Existing Revolving Facility Lender, the commitment of such Existing Revolving Facility Lender to make Existing Revolving Facility Loans pursuant to Section 2.01, expressed as an amount representing the maximum aggregate permitted amount of such Existing Revolving Facility Lender’s Revolving Facility Credit Exposure hereunder, as such commitment may be (a) reduced from time to time pursuant to Section 2.08 and (b) reduced or increased from time to time pursuant to assignments by or to such Lender under Section 9.04. The initial amount of each Existing Revolving Facility Lender’s Existing Revolving Facility Commitment is an amount equal to its Revolving Facility Commitment as set forth in the Second Restatement Agreement (giving effect to any Joinder (as such term is used therein) executed and delivered under and in accordance therewith), the First Incremental Amendment, or in the Assignment and Acceptance pursuant to which such Existing Revolving Facility Lender shall have assumed its Existing Revolving Facility Commitment, as applicable. The aggregate amount of the Existing Revolving Facility Commitments of all Existing Revolving Facility Lenders on the First Incremental Amendment Effective Date is $90.0 million.

(D) Section 1.01 of the Credit Agreement is hereby further amended by adding the following immediately following the text “Second Restatement Agreement” in the definition of “Loan Documents”:

“, the First Incremental Amendment”

(ii) Amendments to Schedules:

The Schedules to the Credit Agreement are hereby amended by adding Schedule 1.01(BC) to the Credit Agreement, attached hereto as Exhibit B, immediately following Schedule 1.01(BB) of the Credit Agreement, and by updating the table of contents to reflect this addition.

(c) Upon the effectiveness of the increase in Existing Revolving Facility Commitments pursuant to this First Incremental Amendment, each Existing Revolving Facility Lender immediately prior to such increase will automatically and without further act be deemed to have assigned to the Incremental Revolving Facility Commitment Lender, and the Incremental Revolving Facility Lender will automatically and without further act be deemed to have assumed, a portion of such Existing Revolving Facility Lender’s participations hereunder in outstanding Letters of Credit and Swingline Loans such that, after giving effect to such Existing Revolving Facility increase and each such deemed assignment and assumption of participations, the percentage of the aggregate outstanding (A) participations hereunder in Letters of Credit and (B) participations hereunder in Swingline Loans held by each Existing Revolving Facility Lender (including the Incremental Revolving Facility Lender) will equal such Existing Revolving Facility Lender’s Revolving Facility Percentage. Any Existing Revolving Facility Loans outstanding immediately prior to the First Incremental Effective Date that are Eurocurrency Loans will (except to the extent otherwise repaid in accordance with the Credit Agreement) continue to be held by, and all interest thereon will continue to accrue for the accounts of, the Existing Revolving Facility Lenders holding such Existing Revolving Facility Loans immediately prior to the First Incremental Effective Date, in each case until the last day of the then-current Interest Period applicable to any such Existing Revolving Facility Loan, at which time it will be repaid or refinanced with new Existing Revolving Facility Loans made pursuant to Section 2.01(d) of the Credit Agreement in accordance with the Revolving Facility Percentages of the Existing Revolving Facility Lenders after giving effect to the Existing Revolving Commitment Increase pursuant hereto; provided, however, that upon the occurrence of any Event of Default, the Incremental Revolving Facility Lender will promptly purchase (for cash at face value) assignments of portions of such outstanding Existing Revolving Facility Loans of other Existing Revolving Facility Lenders so that, after giving effect thereto, all Existing Revolving Facility Loans that are Eurocurrency Loans are held by the Existing Revolving Facility Lenders in accordance with their then-current Revolving Facility Percentages. Any such assignments shall be effected in accordance with the provisions of Section 9.04 of the Credit Agreement; provided that the parties hereto hereby consent to such assignments and the minimum assignment amounts and processing and recordation fee set forth in Section 9.04(b) shall not apply thereto. If there are any ABR Revolving Loans outstanding on the First Incremental Effective Date, such Loans shall either be prepaid by the Borrower on such date or refinanced on such date (subject to satisfaction of applicable borrowing conditions) with Existing Revolving Facility Loans made on such date by the Existing Revolving Facility Lenders (including the Incremental Revolving Facility Lender) in accordance with their Revolving Facility Percentages. In order to effect any such refinancing, (i) the Incremental Revolving Facility Lender will make ABR Revolving Loans to the Borrower by transferring funds to the Administrative Agent in an amount equal to the aggregate outstanding amount of such Loans of such Type times a percentage obtained by dividing the amount of the Incremental Revolving Facility Lender’s Existing Revolving Facility Commitment by the aggregate amount of the Existing Revolving Facility Commitments (after giving effect to the Existing Revolving Facility Commitment of the Incremental

Revolving Facility Lender on such date) and (ii) such funds will be applied to the prepayment of outstanding ABR Revolving Loans held by the Existing Revolving Facility Lenders other than the Incremental Revolving Facility Lender, and transferred by the Administrative Agent to the Existing Revolving Facility Lenders other than the Incremental Revolving Facility Lender, in such amounts so that, after giving effect thereto, all ABR Revolving Loans will be held by the Existing Revolving Facility Lenders in accordance with their then-current Revolving Facility Percentages. On the First Incremental Effective Date, the Borrower will pay to the Administrative Agent, for the accounts of the Existing Revolving Facility Lenders receiving such prepayments, accrued and unpaid interest on the principal amounts of their Existing Revolving Facility Loans being prepaid. The Administrative Agent and the Existing Revolving Facility Lenders party hereto hereby agree that the minimum borrowing, pro rata borrowing and pro rata payment requirements contained elsewhere in the Credit Agreement shall not apply to the transactions effected pursuant to the immediately preceding sentence.

SECTION 4. Conditions of Effectiveness of the First Incremental Amendment.
