Annex I

Conditions

The obligations of Deutsche Bank under this Agreement are subject to the conditions set forth below. Deutsche Bank may waive, in its sole discretion, any of these conditions by written notice to the Seller.

Delivery of the Shares. The Shares shall be delivered at the Closing Time in accordance with the terms of this Agreement,. [Seller has legal obligation to deliver clean shares – it is not the DB’s obligation – we are simply facilitating].

Accuracy of Seller’s Representations and Warranties. Each of the representations and warranties of the Seller shall have been correct when given or made and shall be correct in all material respects at the Closing Time as though it had been given or made at the Closing Time, and, if requested, Deutsche Bank shall have received a certificate of an executive officer or director of the Seller confirming satisfaction of this condition.

No Force Majure Event Has Occurred. None of the following events shall have occurred between the date of this Agreement and the Closing Time: (A) a suspension of trading generally on the New York Stock Exchange or a limitation on prices (other than limitations on hours or numbers of days of trading) for securities on the New York Stock Exchange, (B) any outbreak or escalation of hostilities or declaration of war or national emergency or other national or international calamity or crisis or change in economic or political conditions if the effect of such outbreak, escalation, declaration, emergency, calamity, crisis or change on the financial markets of the United States would, in Deutsche Bank’s reasonable judgement, make it impracticable or inadvisable to market the Shares or to enforce contracts for the sale of the Shares, or (C) the declaration of a banking moratorium by United States or New York State authorities.

In the event that Seller shall not have delivered the Shares as required, [see comment above] or any of the above conditions shall not have been satisfied (or waived in writing), by or at the Closing Time, Deutsche Bank shall not be bound to proceed with any purchase of the Shares and this Agreement shall cease to have effect, except for the liability of the Seller arising before or in relation to such termination and as otherwise provided herein, provided that, if the Seller delivers less than all of the Shares by or at the Closing Time, Deutsche Bank shall also have the option to effect the purchase of any number of such Shares as are delivered at the agreed purchase price per share, but such partial purchase shall not relieve the Seller from liability for its default with respect to the Shares not purchased.

Indemnification

The Seller agrees to indemnify and hold harmless Deutsche Bank against any losses, claims, damages, demands or liabilities to which Deutsche Bank may become subject in so far as such losses, claims, damages or liabilities (or actions in respect hereof) relate to or arise out of any breach or alleged breach of the terms of this Agreement or as a result of any of the representations and warranties of the Seller being, or alleged to be, untrue or misleading in any respect. This indemnity shall not, however, apply to the extent that it is finally judicially determined that such losses, claims, damages or liabilities resulted primarily from Deutsche Bank’s willful default [see comment above]. The Seller agrees to reimburse Deutsche Bank promptly for any duly itemized expenses (including reasonable counsel’s fees) reasonably incurred by Deutsche Bank in connection with investigating or defending any such action or claim. The indemnification obligations of the Seller are in addition to any liability the Seller may otherwise have and shall extend, upon the same terms and conditions, to the respective directors, officers, employees and controlling persons of Deutsche Bank. The indemnification obligations of the Seller shall survive termination of this Agreement.
