WHEREAS, terms used in this First Amendment which are defined in the Credit Agreement shall have the meanings specified therein, as applicable (unless otherwise defined herein).

NOW, THEREFORE, for good and valuable consideration, the parties hereto hereby agree as follows:

(ii) The following new terms are added to Section 1.1 in appropriate alphabetical order:

“First Amendment Date” means the effective date of the First Amendment pursuant to Section 3 thereof.

Borrower shall provide an Acknowledgment Letter duly executed by each Eligible Investor (and in respect of any Subsequent Investor that is an Eligible Investor, Borrower shall provide an Acknowledgment Letter duly executed by such Subsequent Investor), substantially in the form attached hereto as Exhibit 2.21(g)-l. Notwithstanding the foregoing, in the event that an Eligible Investor has executed a Subscription Agreement containing substantially the same terms as an Acknowledgment Letter, Borrower shall not be required to provide an Acknowledgment Letter for such Eligible Investor. Borrower shall

provide notice to each Investor that is not an Eligible Investor of the grant by Borrower of security interests granted pursuant to the Security Documents, which notice may be made by Borrower pursuant to disclosure thereof in Borrower’s next relevant SEC filings to be made following the Closing Date.”

(c) The last sentence of Section 5.4(b) of the Credit Agreement is hereby amended and restated as follows:

“Borrower shall obtain an Acknowledgment Letter (or a Subscription Agreement containing substantially the same terms as an Acknowledgment Letter) from each Subsequent Investor that becomes an Eligible Investor.”

Section 2. Acknowledgement of Control Agreement. The Borrower and Deutsche Bank hereby agree that the Account Control Agreement delivered on the Closing Date by Borrower, JPMorgan Chase Bank, N.A., as Account Bank and the Administrative Agent satisfies the requirements of Section 2.21(e) of the Credit Agreement and no transfer of the Collateral Account or further amendment or replacement of the Account Control Agreement shall be required under Section 2.21(e) of the Credit Agreement.

Section 3. Representations and Warranties. The Borrower hereby (i) confirms and reaffirms that the representations and warranties contained in the Credit Agreement and the other Loan Documents, to the extent applicable to Borrower, are true and correct in all material respects as of the First Amendment Date, except to the extent that they relate to a particular date, in which case they are true and correct in all material respects on and as of such date as if made on and as of such date, (ii) confirms that, after taking into account this First Amendment, there exists no Event of Default or, to Borrower’s knowledge, no event, which with the giving of notice or lapse of time or both, would become an Event of Default, under the Credit Agreement, and (iii) represents and warrants that Borrower has the power and requisite authority to execute, deliver, and perform its obligations under this First Amendment and is duly authorized to, and has taken all action necessary to authorize it to execute, deliver, and perform its respective obligations under this First Amendment.

All references to the Credit Agreement in any other document or instrument shall be deemed to mean the Credit Agreement as amended by this First Amendment. This First Amendment shall not constitute a novation of the Credit Agreement or any other Loan Document, but shall constitute an amendment thereof.

Section 6. Fees and Expenses. In accordance with Section 9.6 of the Credit Agreement, Borrower agrees to pay Administrative Agent all reasonable and documented out-of-pocket expenses incurred by Administrative Agent and Lenders, including, without limitation, reasonable and documented legal fees, in connection with preparing, executing, delivering and administering this First Amendment.
