B. Capitalized terms used herein shall have the respective meanings ascribed thereto in the Note Purchase Agreement unless herein defined or the context shall otherwise require.

C. All requirements of law have been fully complied with and all other acts and things necessary to make this First Amendment a valid, legal and binding instrument according to its terms for the purposes herein expressed have been done or performed.

NOW, THEREFORE, the Company and the Noteholders, in consideration of good and valuable consideration the receipt and sufficiency of which is hereby acknowledged, do hereby agree as follows:

SECTION 1. AMENDMENTS.

Section 1.1. The parties hereto agree that the Note Purchase Agreement shall be amended as follows (with changes showing as deleted struck out (indicated textually in the same manner as the following example: stricken text) and added text double-underlined (indicated textually in the same manner as the following example: double-underlined text):

Section 8.2. Optional Prepayments with Prepayment Settlement Amount. The Company may, at its option, upon notice as provided below, prepay at any time all, or from time to time, to the extent permitted by the last sentence of this Section 8.2, any part of, the Notes, in an amount not less than 10% of the aggregate principal amount of the Notes then outstanding in the case of a partial prepayment, at 100% of the principal amount so prepaid, and the Prepayment Settlement Amount applicable to such Series or tranche of Notes determined for the prepayment date with respect to such principal amount. The

Company will give each holder of such Series or tranche of Notes written notice of each optional prepayment under this Section 8.2 not less than 10 days and not more than 60 days prior to the date fixed for such prepayment unless the Company and the Required Holders agree to another time period pursuant to Section 17. Each such notice shall specify such date (which shall be a Business Day), the aggregate principal amount of the such Series or tranche of Notes to be prepaid on such date, the principal amount of each Note held by such holder to be prepaid (determined in accordance with Section 8.3), and the interest in such Series or tranche to be paid on the prepayment date with respect to such principal amount being prepaid, and shall be accompanied by a certificate of a Senior Financial Officer as to the estimated Prepayment Settlement Amount applicable to such Series or tranche of Notes due in connection with such prepayment (calculated as if the date of such notice were the date of the prepayment), setting forth the details of such computation. Two Business Days prior to such prepayment, the Company shall deliver to each holder of such Notes in such Series or tranche a certificate of a Senior Financial Officer specifying the calculation of such Prepayment Settlement Amount applicable to such Series or tranche of Notes as of the specified prepayment date. Notwithstanding the foregoing and anything contained in this Section to the contrary, if and so long as any Default or Event of Default shall have occurred and be continuing, or if such partial prepayment is made at a time when the Prepayment Settlement Amount applicable to such Series or tranche is the Make-Whole Amount, any partial prepayment of the Notes pursuant to the provisions of this Section 8.2 shall be allocated among all of the Notes of all Series and tranches at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof.

Section 8.3. Allocation of Partial Prepayments. In the case of each partial prepayment of the Notes pursuant to Section 8.2, the principal amount of the Notes to be prepaid shall be allocated among all of the Notes (or the applicable Series or tranche of Notes) at the time outstanding in proportion, as nearly as practicable, to the respective unpaid principal amounts thereof not theretofore called for prepayment. For the avoidance of doubt, so long as no Event of Default then exists, the Company may optionally prepay any Series or tranche of Notes without the allocation of such prepayment among all of the Notes at the time outstanding, if such Series or tranche, as applicable, is paid in full at a time when the Prepayment Settlement Amount applicable to such Series or tranche is not the Make-Whole Amount.

Section 8.4. Maturity; Surrender, Etc. In the case of each prepayment of any Series or tranche of Notes pursuant to this Section 8, the principal amount of each Note to be prepaid shall mature and become due and payable on the date fixed for such prepayment, together with interest on such principal amount accrued to such date and the applicable Prepayment Settlement Amount, if any, or Make-Whole Amount, if any. From and after such date, unless the Company shall fail to pay such principal amount when so due and payable, together with the interest and Prepayment Settlement Amount, if any, or Make-Whole Amount, if any, as aforesaid, interest on such principal amount shall cease to accrue. Any Note paid or prepaid in full shall be surrendered to the Company and cancelled and shall not be reissued, and no Note shall be issued in lieu of any prepaid principal amount of any Note.

Section 8.5. Purchase of Notes. The Company will not and will not permit any Affiliate to purchase, redeem, prepay or otherwise acquire after the date of the Closing, directly or indirectly, any of the outstanding Notes except (a) upon the payment or prepayment of the such Notes in accordance with this Agreement and the such Notes or (b) pursuant to an offer to purchase made by the Company or an Affiliate pro rata to the holders of all Notes at the time outstanding upon the same terms and conditions. Any such offer shall provide each applicable holder with sufficient information to enable it to make an informed decision with respect to such offer, and shall remain open for at least 10 Business Days. If the holders of more than 25% of the principal amount of the Notes in such Series or tranche then outstanding accept such offer, the Company shall promptly notify the remaining holders of Notes in such Series or tranche of such fact and the expiration date for the acceptance by holders of in such Series or tranche of Notes of such offer shall be extended by the number of days necessary to give each such remaining holder at least 5 Business Days from its receipt of such notice to accept such offer. The Company will promptly cancel all Notes acquired by it or any Affiliate after the date of the Closing pursuant to any payment, prepayment or purchase of Notes pursuant to this Agreement and no Notes may be issued in substitution or exchange for any such Notes. For the avoidance of doubt, no Prepayment Settlement Amount shall be owed in connection with any prepayment made pursuant to this Section 8.5(b) unless offered by the Company.

This First Amendment shall be construed in connection with and as part of the Note Purchase Agreement, and except as modified and expressly amended by this First Amendment, all terms, conditions and covenants contained in the Note Purchase Agreement are hereby ratified and shall be and remain in full force and effect.
