Termination of Employment.  The Employee and the Company will each have the option to terminate Employee’s employment by providing twelve (12) months' prior written notice to the other party. In such event, the Employee shall continue to perform all required responsibilities and duties on a full-time basis for the duration of the twelve (12) months' notice period.

Garden Leave.  The Company shall be entitled to release the Employee from his duty to work ("Garden Leave") at any time. During the period of Garden Leave ("Garden Leave Period"), the Employee undertakes not to pursue any employment or other assignment without obtaining prior written consent from the competent Committee of the Board. If such written consent is given and the Employee takes up new employment during the Garden Leave Period, the employment with the Company shall end as of the day preceding the start of such new employment or self-employment. For the avoidance of doubt, all payments due up to the end of the employment shall be paid and the Employee shall not be entitled to any further payments in respect of the Annual Base Salary and, if applicable, bonus payments pro rata to the original end date. Any outstanding (unvested or vested) long-term incentives pursuant to the LTIP shall be treated in accordance with the applicable plan rules. In the event that the Company, in its sole discretion, releases the Employee from his duty to work during the notice period, any outstanding, untaken or accrued vacation or holiday entitlements shall be taken during such Garden Leave Period and shall be, in any event, deemed to be compensated and taken during such period. Consequently, vacation days will not be paid out.

had adequate time to consider entering into this Agreement prior to signing, including, without limitation, the opportunity to discuss the terms and conditions of this Agreement, as well as its legal consequences, with an attorney of Your choice, at Your own expense.

Best-Net Cutback.  If there is a change of ownership or effective control or change in the ownership of a substantial portion of the assets of the Company (within the meaning of Section 280G of the Code) and any payment or benefit (including payments and benefits pursuant to this Agreement) that the Employee would receive from the Company or otherwise (“Transaction Payment”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code and (ii) but for this sentence, be subject to the excise tax imposed by Section 4999 of the Code (the “Excise Tax”), then the Company shall cause to be determined, before any amounts of the Transaction Payment are paid to the Employee, which of the following two alternative forms of payment would result in the Employee receipt, on an after-tax basis, of the greater amount of the Transaction Payment notwithstanding that all or some portion of the Transaction Payment may be subject to the Excise Tax: (A) payment in full of the entire amount of the Transaction Payment (a “Full Payment”), or (B) payment of only a part of the Transaction Payment so that the Employee receives the largest payment possible without the imposition of the Excise Tax (a “Reduced Payment”), and the Employee shall be entitled to payment of whichever amount that shall result in a greater after-tax amount for the Employee.  For purposes of determining whether to make a Full Payment or a Reduced Payment, the Company shall cause to be taken into account all applicable federal, state and local income and employment taxes and the Excise Tax (all computed at the highest applicable marginal rate, net of the maximum reduction in federal income taxes which could be obtained from a deduction of such state and local taxes).  If a Reduced Payment is made, the reduction in payments and/or benefits will occur in the following order: (1) first, reduction of cash payments, in reverse order of scheduled payment date (or if necessary, to zero), (2) then, reduction of non-cash and non-equity benefits provided to the Employee, on a pro rata basis (or if necessary, to zero) and (3) then, cancellation of the acceleration of vesting of equity award compensation in the reverse order of the date of grant of the Employee’s equity awards.

280G Accountants.  Unless the Employee and the Company otherwise agree in writing, any determination required under this section shall be made in writing by the Company’s independent public accountants (the “Accountants”), whose determination shall be conclusive and binding upon the Employee and the Company for all purposes.  For purposes of making the calculations required by this section, the Accountants may make reasonable assumptions and approximations concerning applicable taxes and may rely on reasonable, good faith interpretations concerning the application of Sections 280G and 4999 of the Code.  The Accountants shall provide detailed supporting calculations to the Company and the Employee as requested by the Company or the Employee.  The Employee and the Company shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this section.  The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this section as well as any costs incurred by the Employee with the Accountants for tax planning under Sections 280G and 4999 of the Code.

SECTION 409A.

General.  The parties hereto acknowledge and agree that, to the extent applicable, this Agreement shall be interpreted in accordance with, and incorporate the terms and conditions required by, Section 409A of the Code and the Department of Treasury Regulations and other interpretive guidance issued thereunder, including without limitation any such regulations or other guidance that may be issued after the Effective Date (“Section 409A”).  Notwithstanding any provision of this Agreement to the contrary, in the event that the Company determines that any amounts payable hereunder will be taxable currently to the Employee under Section 409A(a)(1)(A) of the Code and related Department of Treasury guidance, the Company and the Employee shall cooperate in good faith to (i) adopt such amendments to this Agreement and appropriate policies and procedures, including amendments and policies with retroactive effect, that they mutually determine to be necessary or appropriate to preserve the intended tax treatment of the benefits provided by this Agreement, to preserve the economic benefits of this Agreement, and to avoid less-favorable accounting or tax consequences for the Company, and/or (ii) take such other actions as mutually determined to be necessary or appropriate to exempt the amounts payable hereunder from Section 409A or to comply with the requirements of Section 409A and thereby avoid the application of penalty taxes thereunder; provided, however, that this Section 21(a) does not create an obligation on the part of the Company to modify this Agreement and does not guarantee that the amounts payable hereunder will not be subject to interest or penalties under Section 409A, and in no event whatsoever shall the Company or any of its affiliates be liable for any additional tax, interest or penalties that may be imposed on the Employee as a result of Section 409A or any damages for failing to comply with Section 409A.

Special Rules.  Notwithstanding any provision to the contrary in this Agreement: (i) if the Employee is deemed at the time of Employee’s “separation from service” (within the meaning of Section 1.409A-1(h) of the Department of Treasury Regulations) to be a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code, to the extent that delayed commencement of any portion of the termination benefits to which the Employee is entitled under this Agreement (after taking into account all exclusions applicable to such termination benefits under Section 409A), is required in order to avoid a prohibited distribution under Section 409A(a)(2)(B)(i) of the Code, such portion of the Employee’s termination benefits shall not be provided to the Employee prior to the earlier of (A) the expiration of the six-month period measured from the date of the Employee’s separation from service with the Company and (B) the date of the Employee’s death; provided that upon the earlier of such dates, all payments deferred pursuant to this Section 21(b)(i) shall be paid to the Employee in a lump sum, and any remaining payments due under this Agreement shall be paid as otherwise provided herein; (ii) the determination of whether the Employee is a “specified employee” for purposes of Section 409A(a)(2)(B)(i) of the Code as of the time of Employee’s separation from service shall be made by the Company in accordance with the terms of Section 409A and applicable guidance thereunder (including, without limitation, Section 1.409A-1(i) of the Department of Treasury Regulations and any successor provision thereto); and (iii) to the extent that any reimbursement of expenses or in-kind benefits constitutes “deferred compensation” under Section 409A, (A) such reimbursement or benefit shall be provided no later than December 31 of the year following the year in which the expense was incurred, (B) the amount of expenses reimbursed in one year shall not affect the amount eligible for reimbursement in any subsequent year, (C) the amount of any in-kind benefits provided in one year shall not affect the amount of in-kind benefits provided in any other year and (D) the right to any benefits or reimbursements or in-kind benefits may not be liquidated or exchanged for any other benefit.  Neither the Employee nor any of the Employee’s creditors or beneficiaries shall have the right to subject any “deferred compensation” under Section 409A payable under this Agreement to any anticipation, alienation, sale, transfer, assignment, pledge, encumbrance, attachment or garnishment.  Except as permitted under Section 409A, any “deferred compensation” under Section 409A payable to the Employee or for Employee’s benefit may not be reduced by, or offset against, any amount owing by Employee to the Company or any of its affiliates.
