POWER OF ATTORNEY

KNOW ALL MEN BY THESE PRESENTS, that I, the undersigned Giorgio Enrico Thyssen-Bornemisza, residing at TBG, 1 Avenue des Citronniers, MC-98000 Monaco, do hereby make, constitute, designate and appoint Clifford Thring (the “Attorney”) as my special attorney and authorise the said Attorney to appear in my place and stead to do all or any of the following acts, deeds or things, that is to say:

1.	To execute and file any and all documents required to be filed by me with the Securities and Exchange Commission (the “SEC”), including Form ID, Forms 3, 4, 5 and 144 and Schedules 13G and 13D and all amendments thereto;
2.	To do and perform any and all acts which may be necessary or desirable to prepare, complete and execute such Form ID, Forms 3, 4, 5 and 144 and Schedules 13G and 13D, complete and execute any amendment or amendments thereto, and timely deliver and file such forms, schedules or amendments with the SEC and any stock exchange or similar authority; and
3.	To take any other action of any type whatsoever in connection with the foregoing which, in the opinion of the Attorney, may be for my benefit, in my best interest, or legally required, it being understood that the documents executed by such Attorney on behalf of the undersigned pursuant to this Power of Attorney shall be in such form and shall contain such terms and conditions as such Attorney may approve in such Attorney’s discretion.

The undersigned hereby grants to such Attorney full power and authority to do and perform any and every act and thing whatsoever requisite, necessary, or proper to be done in the exercise of any of the rights and powers herein granted, as fully to all intents and purposes as the undersigned might or could do, with full power of substitution or revocation, hereby ratifying and confirming all that such Attorney, or such Attorney’s substitute or substitutes, shall lawfully do or cause to be done by virtue of this Power of Attorney and the rights and powers herein granted.

The undersigned acknowledges that the foregoing Attorney, in serving in such capacity at the request of the undersigned, is not assuming nor relieving any of the responsibilities of the undersigned to comply with Section 16 of the Securities Exchange Act of 1934, as amended (“Exchange Act”).

The undersigned also acknowledges that the foregoing Attorney does not assume (i) any liability for the responsibility of the undersigned to comply with the requirements of the Exchange Act, (ii) any liability for the failure by the undersigned to comply with such requirements, or (iii) any of the obligations or liabilities of the undersigned for profit disgorgement under Section 16(b) of the Exchange Act.

This Power of Attorney shall be effective immediately upon execution and shall be revoked by the undersigned giving to such Attorney acting hereunder written notification of the revocation, which notice shall not be considered binding unless actually received.  Absent such revocation, this Power of Attorney shall remain in effect for so long as the undersigned is subject to the reporting requirements imposed by Section 13 or Section 16 of the Exchange Act.

I the undersigned hereby declare that this Power of Attorney shall not be affected by my disability or incapacity and that as against me and all persons claiming under me, everything which my Attorney shall do or cause to be done shall be valid and effectual in favor of any person claiming a benefit thereunder, who, before the doing thereof, shall not have had notice of revocation of this instrument.

This Power of Attorney shall be governed by Swiss law.
