Notwithstanding anything to the contrary contained in this Agreement, this Agreement does not limit Executive’s ability to communicate with any government agency or otherwise participate in any investigation or proceeding that may be conducted by any government agency, including providing documents or other information, without notice to the Company or its affiliates. This Agreement does not limit Executive’s right to receive an award for information provided to any government agencies. 9.

Fax: (▇▇▇) ▇▇▇-▇▇▇▇ (II) If to Executive, at Executive’s residential address as currently on file with the Company. (g) Survival. The Company and Executive hereby agree that certain provisions of this Agreement, including, but not limited to, Sections 8, 9, 10 and 11, shall survive the expiration of the Employment Period in accordance with their terms. (h) Further Assurances. Each party hereto agrees with the other party hereto that it will cooperate with such other party and will execute and deliver, or cause to be executed and delivered, all such other instruments and documents, and will take such other actions, as such other party may reasonably request from time to time, to effectuate the provisions and purpose of this Agreement. (i) Section 409A. (i) The parties intend that any amounts payable hereunder comply with or are exempt from Section 409A (“Section 409A”) of the Internal Revenue Code of 1986, as amended (the “Code”) (including under Treasury Regulation §§ 1.409A-1(b)(4) (“short-term deferrals”) and (b)(9) (“separation pay plans,” including the exceptions under subparagraph (iii) and subparagraph (v)(D)) and other applicable provisions of Treasury Regulation §§ 1.409A-1 through A-6). For purposes of Section 409A, each of the payments that may be made under this Agreement shall be deemed to be a separate payment for purposes of Section 409A. This Agreement shall be administered, interpreted and construed in a manner that does not result in the imposition of additional taxes, penalties or interest under Section 409A. The Company and Executive agree to negotiate in good faith to make amendments to the Agreement, as the parties mutually agree are necessary or desirable to avoid the imposition of taxes, penalties or interest under Section 409A. Neither the Company nor Executive shall have the right to accelerate or defer the delivery of any such payments or benefits except to the extent specifically permitted or required by Section 409A. With respect to the time of payments of any amounts under the Agreement that are “deferred compensation” subject to Section 409A, references in the Agreement to “termination of employment” (and substantially similar phrases) shall mean “separation from service” within the meaning of Section 409A. For the avoidance of doubt, it is intended that any expense reimbursement made to Executive hereunder shall be exempt from Section 409A. Notwithstanding the foregoing, if any expense reimbursement made hereunder shall be determined to be “deferred compensation” within the meaning of Section 409A, then (a) the amount of the indemnification payment or expense reimbursement during one taxable year shall not affect the amount of the expense reimbursement during any other taxable year, (b) the expense reimbursement shall be made on or before the last day of Executive’s taxable year following the

 
#9936593 v5 \027606 \0401 13 year in which the expense was incurred and (c) the right to expense reimbursement hereunder shall not be subject to liquidation or exchange for another benefit. (ii) In the event that Executive is a “specified employee” (as described in Section 409A), and any payment or benefit payable pursuant to this Agreement constitutes deferred compensation subject to the six-month delay requirement described in Section 409A(2)(b), then no such payment or benefit shall be made before six months after Executive’s “separation from service” (as described in Section 409A) (or, if earlier, the date of the Executive’s death). Any payment or benefit delayed by reason of the prior sentence shall be paid out or provided in a single lump sum at the end of such required delay period in order to catch up to the original payment schedule. (iii) The parties hereto intend that the Severance payments up to two times the dollar limit in effect under Section 401(a)(17) of the Code for the year in which Executive’s “separation from service” (as described in Section 409A) occurs shall be exempt from Section 409A to the extent permitted under Treasury Regulation Section 1.409A-1(b)(9)(iii) (the “two- times/two-year” exemption). In determining which installments of Severance are taken into account in applying the two-times/two-year exemption, any other exemptions from Section 409A (including, the short-term deferral exception, if applicable) shall be taken into account first and the immediately following installments shall then be applied toward the two-times/two-year exception (up to the applicable dollar limit). (j) Section 280G. (i) Notwithstanding anything to the contrary contained in this Agreement or otherwise, to the extent that any payment, distribution or acceleration of vesting to or for the benefit of Executive by the Company (within the meaning of Section 280G of the Code and the regulations thereunder), whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise (the “Total Payments”), is or will be subject to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), then the Total Payments shall be reduced (but not below zero) to the Safe Harbor Amount (as defined below) if and to the extent that a reduction in the Total Payments would result in Executive retaining a larger amount, on an after-tax basis (taking into account federal, state and local income and employment taxes and the Excise Tax), than if Executive received the entire amount of such Total Payments in accordance with their existing terms (taking into account federal, state, and local income and employment taxes and the Excise Tax). For purposes of this Agreement, the term “Safe Harbor Amount” means the largest portion of the Total Payments that would result in no portion of the Total Payments being subject to the Excise Tax. To effectuate the foregoing, the Company shall reduce or eliminate the Total Payments by first reducing or eliminating the portion of the Total Payments which are payable in cash and then by reducing or eliminating non-cash payments, in each case, starting with the payments to be made farthest in time from the Determination (as defined below). (ii) The determination of whether the Total Payments shall be reduced as provided in Section 11(j)(i) and the amount of such reduction shall be made at the Company’s expense by an accounting firm selected by Company from among the 10 largest accounting firms in the United States or by qualified independent tax counsel (the “Determining Party”); provided, that Executive shall be given advance notice of the Determining Party selected by the Company,

 
#9936593 v5 \027606 \0401 14 and shall have the opportunity to reject the selection, within two business days of being notified of the selection, on the basis of that Determining Party’s having a conflict of interest or other reasonable basis, in which case the Company shall select an alternative auditing firm among the 10 largest accounting firms in the United States or alternative independent qualified tax counsel, which shall become the Determining Party. Such Determining Party shall provide its determination (the “Determination”), together with detailed supporting calculations and documentation to the Company and Executive, within 10 business days of the termination of Executive’s employment or at such other time mutually agreed by the Company and Executive. If the Determining Party determines that no Excise Tax is payable by Executive with respect to the Total Payments, it shall furnish Executive with an opinion reasonably acceptable to Executive that no Excise Tax will be imposed with respect to any such payments and, absent manifest error, such Determination shall be binding, final and conclusive upon the Company and Executive. If the Determining Party determines that an Excise Tax would be payable, the Company shall have the right to accept the Determination as to the extent of the reduction, if any, pursuant to Section 11(j)(i), or to have such Determination reviewed by another accounting firm selected by the Company, at the Company’s expense. If the two accounting firms do not agree, a third accounting firm shall be jointly chosen by Executive and the Company, in which case the determination of such third accounting firm shall be binding, final and conclusive upon the Company and Executive. (iii) If, notwithstanding any reduction described in this Section 11(j)(iii), the Internal Revenue Service (“IRS”) determines that Executive is liable for the Excise Tax as a result of the receipt of any of the Total Payments or otherwise, then Executive shall be obligated to pay back to the Company, within 30 calendar days after a final IRS determination or in the event that Executive challenges the final IRS determination, a final judicial determination, a portion of the Total Payments equal to the “Repayment Amount”. The “Repayment Amount” with respect to the payment of benefits shall be the smallest such amount, if any, as shall be required to be paid to the Company so that Executive’s net after-tax proceeds with respect to the Total Payments (after taking into account the payment of the Excise Tax and all other applicable taxes imposed on the Payment) shall be maximized. The Repayment Amount shall be zero if a Repayment Amount of more than zero would not result in Executive’s net after-tax proceeds with respect to the Total Payments being maximized. If the Excise Tax is not eliminated pursuant to this Section 11(j)(iii), Executive shall pay the Excise Tax. (iv) Notwithstanding any other provision of this Section 11(j), if (i) there is a reduction in the Total Payments as described in this Section 11(j), (ii) the IRS later determines that Executive is liable for the Excise Tax, the payment of which would result in the maximization of Executive’s net after-tax proceeds (calculated as if Executive’s benefits had not previously been reduced), and (iii) Executive pays the Excise Tax, then the Company shall pay to Executive those payments or benefits which were reduced pursuant to this Section 11(j) as soon as administratively possible after Executive pays the Excise Tax (but not later than March 15 following the calendar year of the IRS determination) so that Executive’s net after-tax proceeds with respect to the Total Payments are maximized. (v) If, following a reduction of the Total Payments pursuant to Section 11(j)(i), the Determining Party or a court of competent jurisdiction determines that the Total Payments were reduced to a greater extent than required under Section 11(j), then the Company shall as soon as administratively possible (but not later than by March 15 following the calendar year of such

 
#9936593 v5 \027606 \0401 15 determination) pay the amount of such excess reduction to or for the benefit of Executive, together with interest at the applicable federal rate (as defined in Section 7872(f)(2)(A) of the Code), from the date the amount would have otherwise been paid to Executive until the payment date. (vi) To the extent requested by Executive, the Company shall cooperate with Executive in good faith in valuing, and the Determining Party shall take into account the value of, services provided or to be provided by Executive (including, without limitation, Executive’s agreeing to refrain from performing services pursuant to a covenant not to compete or similar covenant, before, on or after the date of a change in ownership or control of the Company (within the meaning of Q&A-2(b) of the final regulations under Section 280G of the Code), such that payments in respect of such services may be considered reasonable compensation within the meaning of Q&A-9 and Q&A-40 to Q&A-44 of the final regulations under Section 280G of the Code and/or exempt from the definition of the term “parachute payment” within the meaning of Q&A-2(a) of the final regulations under Section 280G of the Code in accordance with Q&A-5(a) of the final regulations under Section 280G of the Code. (k) Counterparts. This Agreement may be executed in counterparts, each of which shall be deemed an original and all of which together shall constitute one and the same instrument. The parties hereto agree to accept a signed facsimile copy or “PDF” of this Agreement as a fully binding original. (l) Headings.
