5. Tax Withholding Obligations.

(a) On or before the time you receive a distribution of any Performance Cash Bonus in respect of this Award,  and at any other time as reasonably requested by the Company in accordance with applicable tax laws, you agree to make adequate provision for any sums required to satisfy the federal, state, local and foreign tax withholding obligations of the Company or any Affiliate that arise in connection with this Award (the “Withholding Taxes”).  Specifically, the Company or an Affiliate may, in its sole discretion, satisfy all or any portion of the Withholding Taxes relating to this Award by any means it deems appropriate.  

(b) Unless the Withholding Taxes of the Company and/or any Affiliate are satisfied, the Company will have no obligation to issue to you any Performance Cash Bonus in respect of the Award.

(c) In the event the Company’s obligation to withhold arises prior to the issuance to you of a  Performance Cash Bonus or it is determined after the issuance of a  Performance Cash Bonus to you that the amount of the Company’s withholding obligation was greater than the amount withheld by the Company, you agree to indemnify and hold the Company harmless from any failure by the Company to withhold the proper amount.

6.

10.

13. Unsecured Obligation.  This Award is unfunded, and as a holder of a  vested Performance Cash Bonus, you will be considered an unsecured creditor of the Company with respect to the Company’s obligation, if any, to pay cash or other property pursuant to this Agreement.

14. Compliance with Section 409A of the Code.    This Award is intended to comply with the “short-term deferral” rule set forth in Treasury Regulations Section 1.409A-1(b)(4).  However, if (i) this Award fails to satisfy the requirements of the short-term deferral rule and is otherwise not exempt from, and therefore deemed to be deferred compensation subject to, Section 409A of the Code, (ii) you are deemed by the Company at the time of your “separation from service” (as such term is defined in Treasury Regulations Section 1.409A-1(h) without regard to any alternative definition thereunder) to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code, and (iii) any of the payments set forth herein are issuable upon such separation from service, then to the extent delayed commencement of any portion of such payments is required to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code and the related adverse taxation under Section 409A of the Code, such payments will not be provided to you prior to the earliest of (a) the date that is six months and one day after the date of such separation from service, (b) the date of your death, or (c) such earlier date as permitted under Section 409A of the Code without the imposition of adverse taxation.  Upon the first business day following the expiration of such applicable Code Section 409A(a)(2)(B)(i) period, all payments deferred pursuant to this Section 14 will be paid in a lump sum to you, and any remaining payments due will be paid as otherwise provided herein.  Each installment of Performance Cash Bonus that vests under this Award is a “separate payment” for purposes of Treasury Regulations Section 1.409A-2(b)(2).
