any other respect, it will be interpreted to extend only over the maximum period of time for which it may be enforceable, over the maximum geographical area as to which it may be enforceable, or to the maximum extend in all other respect as to which it may be enforceable, all as determined by such court..

Prior to the Determination Date, the Units subject to the Award and not then vested may not be transferred by the Holder other than by will, the laws of descent and distribution or pursuant to beneficiary designation procedures approved by the Company.

The decision of the Committee regarding any such adjustment shall be final, binding and conclusive.

c..    Compliance with Applicable Law. The Award is subject to the condition that if the listing, registration or qualification of the Stock subject to the Award upon any securities exchange or under any law, or the consent or approval of any governmental body, or the taking of any other action is necessary or desirable as a condition of, or in connection with, the vesting or delivery of Stock hereunder, the Units subject to the Award shall not vest or be delivered, in whole or in part, unless such listing, registration, qualification, consent or approval shall have been effected or obtained, free of any conditions not acceptable to the Company. The Company agrees to use reasonable efforts to effect or obtain any such listing, registration, qualification, consent or approval. Further, Holder agrees that to the extent issuance of Stock in the Holder’s jurisdiction is impossible, illegal, unauthorized, or in the Company’s discretion is imprudent or is otherwise impracticable for any reason, that the Company may, in its discretion, either deem the Award to be a cash award of equivalent cash value or may direct the sale of all Stock subject to the Award and settle the Award in cash locally with the Holder.

The Holder hereby waives any and all rights to compensation or damages as a result of the termination of employment with the Company for any reason whatsoever insofar as those rights result or may result from: (a) the loss or diminution in value of any rights under the Plan; or (b) the Holder ceasing to have any rights under, or ceasing to be entitled to any rights under the Plan as a result of such termination.

f..    Decisions of Board or Committee.

As a further condition precedent to the delivery to the Holder of any Stock subject to the Award, the Holder shall comply with all regulations and requirements of any regulatory authority having control of or supervision over the issuance of the Stock and, in connection therewith, shall execute, on or prior to the payment date of the Award specified in this Agreement, any documents which the Board or any committee authorized by the Board shall in its sole discretion deem necessary or advisable.

The Agreement and the Plan shall be administered in a manner consistent with this intent, and any provision that would cause the Agreement or the Plan to fail to satisfy Section 409A of the Code shall have no force and effect until amended to comply with Section 409A of the Code (which amendment may be retroactive to the extent permitted by Section 409A of the Code and may be made by the Company without the consent of the Holder).

The Holder remains personally responsible for any local compliance requirements resulting from his or her receipt, ownership, and subsequent sale of Common Stock, as well as the transfer of funds abroad, the making of a foreign investment, and the opening or use of a U.S. brokerage account in relation to his or her receipt of Common Stock. For Holder’s whose Award under this Agreement is subject to China SAFE regulations, the Holder agrees to abide by applicable requirements for disposal of vested Stock following termination of employment and hereby affirmatively authorizes the Company to direct the sale or disposal of Stock within 6 months following termination of employment in order to comply with these requirements.

Once delivered, Stock may not be sold within the periods as set forth in Article L. 225-197-1, I of the French Commercial Code.

17.Cash Settlement Relating to Holders in certain Jurisdictions. For the Holder under the laws of their applicable jurisdiction, the delivery of Stock under this Agreement, if any, shall be effective only at such time as counsel to the Company shall have determined that the issuance and delivery of such Stock is in compliance with all applicable laws and regulations of such jurisdiction and the requirements of any securities exchange on which such Stock is traded. Notwithstanding any other provision of the Plan or this Agreement to the contrary, if at any time it is determined by counsel to the Company that the issuance and delivery of Stock pursuant to this Agreement to a Holder in such jurisdiction would for any reason be unenforceable or prohibited as a matter of law or would result in material adverse consequences for the Company or the Holder, then the portion of the Award that would have been settled in Stock shall instead be settled in cash in an amount equal to the value of the Stock that would have been delivered under the Award.
