To the Company and the Exchange Agent:

I/we irrevocably accept the offer to exchange all of my/our Original Shares for Exchange Shares in accordance with the terms and conditions set out in the Prospectus and this Letter of Transmittal (which together, as amended, supplemented or modified from time to time, constitute the "Exchange Offer").

The Exchange Agent and the Company are irrevocably authorized, subject to the withdrawal rights described below, to tender the Original Shares in exchange for the Exchange Shares. Upon the terms and subject to the conditions of the Exchange Offer (and if the Exchange Offer is extended or amended, the terms of any such extension or amendment), effective upon acceptance for the Original Shares tendered herewith, the undersigned appoints the Exchange Agent and the Company as the true and lawful agents and attorneys-in-fact (with full knowledge that the Exchange Agent also acts as agent for the Company) of such holder of Original Shares with respect to such Original Shares, with full power of substitution, to (i) delete the beneficial ownership interest in the Original Shares held through a registered position or in certificated form, (ii) the Original Shares be cancelled and destroyed if in certificated form, and (iii) cause AST as the Company's U.S. Transfer Agent and Registrar (the "Transfer Agent") to deliver the Exchange Shares in the form chosen in Item 2 above, all in accordance with the terms of the Exchange Offer. The power of attorney granted in this paragraph shall be deemed to be irrevocable and coupled with an interest.

The Original Shares will be exchanged free of any encumbrances or other third-party rights whatsoever and with all shareholder rights attached to them. I/we acknowledge that this acceptance will only be regarded as valid if any third party with registered encumbrances or other third-party rights over the Original Shares has approved by signing this Letter of Transmittal that the Original Shares may be exchanged free of any encumbrances or other third-party rights with Exchange Shares. The undersigned represents and warrants that it has full power and authority to tender and exchange the Original Shares and to acquire Exchange Shares upon the exchange of such tendered Original Shares, and that, when the same are accepted for exchange, the tendered Original Shares will be good and unencumbered, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim. The undersigned also warrants that it will, upon request, execute and deliver any additional documents deemed by the Exchange Agent or the Company to be necessary or desirable to complete the exchange of the tendered Original Shares.

By tendering Original Shares and executing this Letter of Transmittal, the undersigned represents that (1) the Exchange Shares acquired pursuant to the Exchange Offer will be, and the Original Shares being tendered were, acquired in the ordinary course of business of the undersigned, (2) the undersigned is not engaging in and does not intend to engage in a distribution of the Exchange Shares, (3) the undersigned does not have an arrangement or understanding with any person to participate in the distribution of such Exchange Shares, (4) the undersigned is not an "affiliate" of the Company within the meaning of Rule 405 under the Securities Act of 1933, as amended, and (5) the undersigned is not acting on behalf of any person who could not truthfully make the foregoing representations. If the undersigned is a broker-dealer that will receive Exchange Shares for its own account in exchange for Original Shares that were acquired as a result of market-making activities or other trading activities, it acknowledges that it will deliver a Prospectus meeting the requirements of the Securities Act of 1933, as amended, in connection with any resale of such Exchange Shares to the extent required by applicable law or regulation or SEC pronouncement. By acknowledging that it will deliver and by delivering a Prospectus meeting the requirements of the Securities Act of 1933, as amended, in connection with any resale of such Exchange Shares, the undersigned is not deemed to admit that it is an "underwriter" within the meaning of the Securities Act of 1933, as amended.

Any holder of Original Shares using the Exchange Offer to participate in a distribution of the Exchange Shares (i) cannot rely on the position of the staff of the Securities and Exchange Commission enunciated in its interpretive letter with respect to Exxon Capital Holdings Corporation (available May 13, 1988) or similar interpretive letters and (ii) must comply with the registration and Prospectus delivery requirements of the Securities Act of 1933, as amended, in connection with a secondary resale transaction.

All authority herein conferred or agreed to be conferred shall survive the death or incapacity of the undersigned and every obligation of the undersigned hereunder shall be binding upon the heirs, personal representatives, successors and assigns of the undersigned. Tendered Original Shares may be withdrawn at any time prior to the Expiration Date in accordance with the terms of this Letter of Transmittal. You may withdraw your tender of Original Shares at any time prior to the Expiration Date.

For a withdrawal of tendered Original Shares to be effective, a written notice of withdrawal must be received by the Exchange Agent or the Company, at their addresses set forth above prior to the Expiration Date. Any such notice of withdrawal must: (i) specify the name of the person who tendered the Original Shares to be withdrawn; (ii) identify the Original Shares to be withdrawn; and (iii) be signed by the holder of such Original Shares in the same manner as the original signature on the Letter of Transmittal by which such Original Shares were tendered or be accompanied by (i) the documents required by the Exchange Agent to unblock the Original Shares and (ii) a properly completed irrevocable proxy authorizing such person to effect such withdrawal on behalf of such holder.

All questions as to the validity, form and eligibility, including time of receipt, of such notices will be determined by the Company, and our determination shall be final and binding on all parties. Any Original Shares withdrawn will be considered not to have been validly tendered for exchange for the purposes of the Exchange Offer. Any Original Shares that have been tendered for exchange but that are not exchanged for any reason will be returned to you without cost promptly after withdrawal, rejection of tender or termination of the Exchange Offer. Properly withdrawn Original Shares may be re-tendered at any time on or prior to the Expiration Date.
