Explanation of Responses:

( 1 )This Form 4 is being filed by Barclays Bank PLC, a public company organized under the laws of England and Wales (the "Reporting Person"), on behalf of various of its indirect wholly-owned subsidiaries. ( 2 )On May 29, 2012, Robert Diamond, the Reporting Person's designee on the Issuer's Board of Directors resigned as a director of the Issuer, and the Reporting Person and its subsidiaries no longer have any right to designate any directors to the Issuer's Board of Directors. As a result, whether or not the Reporting Person was ever a director of the Issuer by deputization, the Reporting Person is no longer a director by deputization. The Reporting Person has previously disclaimed, and continues to disclaim, such possible status as director by deputization.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
