AMOUNT AND TERMS OF THE LOANS

Section 2.1 Loan Commitment.

(a) Subject to the terms and conditions set forth herein, the Lender agrees to make Tranche A revolving loans (“Tranche A Loans”) and Tranche B revolving loans (“Tranche B Loans” and, together with the Tranche A Loans, each a “Loan” and, collectively, the “Loans”) to the Borrower during the Availability Period in an aggregate principal amount at any time outstanding not to exceed the Loan Commitment. The Tranche A Loans and the Tranche B Loans shall be used for the respective purposes set forth in Section 4.5.

(b) During the Availability Period, the Borrower shall be entitled to borrow, prepay or repay, and reborrow the Loans in accordance with the provisions hereof.

Section 2.2 Borrowing Procedure. The Borrower shall give the Lender written notice (or telephonic notice promptly confirmed in writing) of each borrowing to be made by the Borrower substantially in the form of Exhibit A (a “Notice of Borrowing”), each such Notice of Borrowing to be delivered on or prior to the requested date of each borrowing.

Section 2.3 Optional Reduction and Termination of Loan Commitment.

(a) Upon three (3) Business Days’ written notice to the Lender signed by the Borrower, the Borrower may terminate the Loan Commitment, or permanently reduce the Loan Commitment to an amount not less than the then Outstanding Amount of all Loans, provided that each partial reduction of the Loan Commitment shall be in integral multiples of $1,000,000 or more (or such lesser amount as agreed by the Lender).

Section 2.4 Repayment of Loans. On the Maturity Date, the Borrower shall repay in full all Obligations.

Section 2.5 Prepayment. At any time, the Borrower may voluntarily prepay in whole or in part the Loans (together with accrued and unpaid interest thereon) without premium or penalty.

Section 2.6 Interest on Loans.

(a) The Loans shall accrue interest at the Loan Interest Rate.

(b) The Borrower shall pay interest due and payable on the Loans in arrears on each Quarterly Payment Date for the Interest Period most recently ended; provided that the Borrower may pay all or a portion of such interest by adding such amount to the principal amount hereunder (a “PIK Payment”), with the remaining interest (if any) to be paid fully in cash (a “Cash Payment”). A PIK Payment shall be deemed to be made with respect to the portion (if any) of the interest due and payable hereunder for which a Cash Payment is not received by the Lender on the applicable Quarterly Payment Date. For all purposes hereof, references to “principal amount” of the Loans includes any increase in the principal amount as a result of a PIK Payment.

(c) While an Event of Default exists or after acceleration of the Loans in accordance with Article VI, at the option of the Lender, interest on the unpaid principal amount of the Loans (and any unpaid interest with respect thereto) will accrue at the Default Interest Rate (the “Default Interest”). All Default Interest will be payable by the Borrower upon demand by the Lender.

Section 2.7 Computation of Interest. All computations of interest shall be made by the Lender on the basis of a year of 360 days. Each determination by the Lender of an interest amount hereunder shall, except for manifest error, be final, conclusive and binding for all purposes.

Section 2.8 Evidence of Debt. The Loans made by the Lender shall be evidenced by one or more accounts or records maintained by the Lender. The accounts or records maintained by the Lender shall be conclusive absent manifest error of the amount of the Loans made by the Lender to the Borrower and the interest and payments thereon. Any failure so to record or any error in doing so shall not, however, limit or otherwise affect the obligation of the Borrower hereunder to pay any amount owing with respect to the Loans.

Section 2.9 Payments Generally. (a) All payments by the Borrower to the Lender hereunder shall be made to the Lender at the Payment Office in immediately available funds without setoff or counterclaim. If any payment hereunder shall be due on a day that is not a Business Day, the date for payment shall be extended to the next succeeding Business Day, and, in the case of the payment accruing interest, interest thereon shall be made payable for the period of such extension. All payments hereunder shall be made in Dollars.

(b) If on the Maturity Date insufficient funds are received by and available to the Lender to pay fully all amounts of principal and interest due hereunder, such funds shall be applied (i) first, towards payment of interest, and (ii) second, towards payment of principal due hereunder.

Section 2.10 Taxes. (a) Any and all payments by the Borrower under each Loan Document shall be made free and clear of and without deduction for any and all present or future Taxes. If any Taxes shall be required by law to be deducted from or in respect of any sum payable under any Loan Document to the Lender, then the Borrower shall be entitled to make such deduction or withholding and shall timely pay the full amount deducted or withheld to the relevant Governmental Authority in accordance with applicable law and the sum payable by the Borrower shall be increased as necessary so that after such deduction or withholding has been made (including such deductions and withholdings of Taxes applicable to additional sums payable under this Section) the Lender receives an amount equal to the sum it would have received had no such deduction or withholding been made.

(b) The Borrower and the Lender agree that the Loans shall be (and they expect the Loans to be) treated as debt for tax purposes, and neither the Borrower nor the Lender shall take a position contrary to this position on any tax return or through any other action, unless required by a final judgment of a court of competent jurisdiction (as reasonably determined by the Borrower and the Lender in good faith).

Section 2.11 Illegality. Notwithstanding any other provision of this Agreement, if the Lender determines that it is unlawful for the Lender to make Loans or to continue to fund or maintain Loans, then, on notice thereof and demand therefor by the Lender to the Borrower, (i) the obligation of the Lender to make or to continue Loans shall be suspended, and (ii) if Loans are then outstanding, the Borrower shall prepay such Loans within three (3) Business Days.
