8.    Termination. The Company or the Executive may terminate the Executive’s employment, and the Period of Employment, at any time for any reason, or for no reason, subject to compliance with Section 8 hereof.

8.1    Termination for Cause by the Company. The Company may terminate the Executive’s employment, and the Period of Employment, immediately at any time for Cause. For purposes of this Agreement, “Cause” means (a) acts or omissions constituting gross negligence, recklessness or willful misconduct on the part of the Executive with respect to the Executive’s obligations or otherwise relating to the business of the Company; (b) the Executive’s material breach of this Agreement or the Company’s Nondisclosure and Assignment of Ideas Agreement; (c) the Executive’s conviction or entry of a plea of nolo contendere for fraud, misappropriation or embezzlement, any felony, or any crime of moral turpitude; or (d) the Executive’s willful neglect of duties as determined in the sole and exclusive discretion of the Board. In the event the Executive’s employment is terminated in accordance with this subsection, the Executive shall be entitled to receive only the

Base Salary then in effect, prorated to the date of termination, and any accrued but unused PTO as of the date of the termination (the “Standard Entitlements”). All other Company obligations to the Executive pursuant to this Agreement will become automatically terminated and completely extinguished. For the avoidance of doubt, the Executive shall not be entitled to receive the severance package described in subsections 8.2.1 or 8.4.1 below in the event the Executive is terminated in accordance with this subsection.

8.2    Termination Without Cause by the Company/Severance. The Company may terminate the Executive’s employment, and the Period of Employment, under this Agreement without Cause at any time on thirty (30) days’ advance notice, in accordance with subsection 11.2 hereof, to the Executive. At the Company’s election, the Executive may be asked to refrain from coming to the office during such thirty-day notice period. In the event of such termination, the Executive shall be entitled to receive the Standard Entitlements, and a severance package as described in subsection 8.2.1 below, provided the Executive complies with the conditions described in subsection 8.2.2 or 8.3.2 below, as applicable. All other Company obligations to the Executive will be automatically terminated and completely extinguished.

8.2.1    Severance Package. If the Executive’s employment is terminated by the Company pursuant to subsection 8.2 or if the Executive resigns pursuant to subsection 8.3.2, the Executive shall be entitled to receive:

8.2.2    Conditions to Receive Severance Package. In order to receive the severance package described in subsection 8.2.1 above, the Executive must: (i) comply with all surviving provisions of this Agreement as specified in Section 10 below (except Section 3 which would not be applicable); and (ii) execute a separation agreement in a form acceptable to the Company, including a full general release, releasing all claims, known or unknown, that the Executive may have against the Company arising out of or any way related to the Executive’s employment or termination of employment with the Company and a non-disparagement provision. The separation agreement contemplated by this Section 8.2.2 shall not broaden any existing or contemplated obligations on the Executive as set forth in the Agreement. The Executive hereby agrees that, upon breach by the Executive of any of the covenants described in Section 7, all Company obligations to the Executive, including the obligations to provide (or continue to provide) the severance package described in subsection 8.2.1 above, will be automatically terminated and completely extinguished.

8.3    Voluntary Resignation by the Executive. The Executive may voluntarily resign her position with the Company, and the Period of Employment, with or without Good Reason, in accordance with Section 8.3.1 or Section 8.3.2, as applicable.

8.3.1    Resignation without Good Reason. In the event the Executive resigns without Good Reason, the Executive must provide thirty (30) days’ advance notice, in accordance with subsection 11.2, and the Executive shall be entitled to receive only the Standard Entitlements, and no other amount. At the Company’s election, the Executive may be asked to refrain from coming to the office during such thirty-day notice period. All other Company obligations to the Executive

pursuant to this Agreement will become automatically terminated and completely extinguished. For the avoidance of doubt, the Executive shall not be entitled to receive the severance package described in subsection 8.2.1 above or subsection 8.4.1 below.

8.3.2    Resignation for Good Reason. In the event the Executive resigns for Good Reason, the Executive shall be entitled to receive the Standard Entitlements, and the severance package described in subsection 8.2.1 above, provided, the Executive complies with the conditions described in subsection 8.2.2 above. For purposes of this Agreement, “Good Reason” means the Executive’s resignation of employment with the Company following the occurrence of one or more of the following, in each case without the Executive’s consent: (a) a material diminution in the Executive’s Base Salary or in the Executive’s target bonus opportunity under the Incentive Plan as in effect for the year in which the termination occurs; (b) a material diminution in the Executive’s title, authority, duties or responsibilities; (c) a material failure to comply with Section 4 hereof; (d) relocation of the Executive’s primary office more than 50 miles from the Executive’s current office; or (e) any other action or inaction that constitutes a material breach by the Company of this Agreement or the Nondisclosure and Assignment of Ideas Agreement. For purposes of this Agreement, Good Reason shall only exist if the Executive provides a notice of termination for Good Reason, in accordance with subsection 11.2 hereof, within ninety (90) days after the initial existence of such grounds and the Company has had sixty (60) days from the date on which such notice is provided to cure such circumstances. If the Executive does not terminate her employment for Good Reason within sixty (60) days following the end of such sixty (60) day period within which the Company was entitled to remedy the course of conduct constituting Good Reason but failed to do so, then the Executive shall be deemed to have waived her right to terminate for Good Reason with respect to such grounds.

8.4    Termination Upon or Following a Change in Control.

8.4.1    Severance Package. If (x) the Executive’s employment is terminated by the Company other than for Cause or (y) the Executive resigns for Good Reason, in each case, on or within twelve (12) months after a Change in Control (as defined below), the Executive shall be entitled to receive:

8.4.2    Conditions to Receive Severance Package. In order to receive the severance package described in subsection 8.4.1 above, the Executive must: (i) comply with all surviving provisions of this Agreement as specified in Section 10 below; and (ii) execute a separation agreement in a form acceptable to the Company, including a full general release, releasing all claims, known or unknown, that the Executive may have against the Company arising out of or any way related to the Executive’s employment or termination of employment with the Company and a non-disparagement provision. The separation agreement contemplated by this Section 8.4.2 shall not broaden any existing or contemplated obligations on the Executive as set forth in the Agreement. The Executive hereby agrees that, upon breach by the Executive of any of the covenants described in Section 7, all Company obligations to the Executive, including the obligations to provide the severance package described in subsection 8.4.1 above, will be automatically terminated and completely extinguished.

8.4.3    Section 409A Compliance. Payments contemplated pursuant to this Agreement are intended to comply with Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”) and the regulations promulgated thereunder (“Section 409A”) (including the provisions for exceptions and exemptions from Section 409A) and all provisions of

this Agreement shall be construed and interpreted in a manner consistent with the requirements for avoiding taxes and penalties under Section 409A. If any payment(s) to the Executive under the terms of this Agreement or any plans is determined to constitute a payment of nonqualified deferred compensation for purposes of Section 409A payable on account of a “separation from service” (as defined under Section 409A) that is not exempt from Section 409A as involuntary separation pay or a short-term deferral (or otherwise), such payment(s) shall be delayed until the date that is six months and one day after the date of the Executive’s separation from service with the Company (or, if sooner, the date of the Executive’s death), if and only to the extent necessary to comply with the special rule for certain “specified employees” set forth in Code Section 409A(a)(2)(B)(i). Upon the expiration of the period described in the preceding sentence, all payments and benefits delayed pursuant to this subsection (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Executive in a lump sum without interest, and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein. A termination of employment shall not be deemed to have occurred for purposes of any provision of this Agreement providing for the payment of any amounts or benefits upon or following a termination of employment unless such termination is also a “separation from service” within the meaning of Section 409A and, for purposes of any such provision of this Agreement, references to a “termination,” “termination of employment” or like terms shall mean “separation from service.” Except as otherwise expressly provided herein, to the extent any expense reimbursement or the provision of any in-kind benefit under this Agreement is determined to be subject to Section409A, the amount of any such expenses eligible for reimbursement, or the provision of any in-kind benefit, in one calendar year shall not affect the expenses eligible for reimbursement in any other taxable year (except for any life-time or other aggregate limitation applicable to medical expenses), in no event shall any expenses be reimbursed after the last day of the calendar year following the calendar year in which such expenses are incurred, and in no event shall any right to reimbursement or the provision of any in-kind benefit be subject to liquidation or exchange for another benefit. Each payment made under this Agreement shall be treated as a “separate payment” within the meaning of Section 409A.

8.4.4    280G. (a)    Notwithstanding anything contained in this Agreement to the contrary, to the extent that any payment, benefit or distribution of any type to or for the benefit of the Executive by the Company or any of the Related Entities, whether paid or payable, provided or to be provided, or distributed or distributable pursuant to the terms of this Agreement or otherwise (including, without limitation, any accelerated vesting of stock options or other equity-based awards) (collectively, the “Total Payments”) would be subject to the excise tax imposed under Section 4999 of the Code, then the Total Payments shall be reduced (but not below zero) so that the maximum amount of the Total Payments (after reduction) shall be one dollar ($1.00) less than the amount which would cause the Total Payments to be subject to the excise tax imposed by Section 4999 of the Code, to the extent that the Executive will retain more of the Total Payments on an after-tax basis following this reduction than if the full amount were payable. Unless the Executive shall have given prior written notice to the Company to effectuate a reduction in the Total Payments if such a reduction is required, any such notice consistent with the requirements of Section 409A to avoid the imputation of any tax, penalty or interest thereunder, the Company shall reduce or eliminate the Total Payments by first reducing or eliminating any cash severance benefits (with the payments to be made furthest in the future being reduced first), then by reducing or eliminating any accelerated vesting of stock options or similar awards, then by reducing or eliminating any accelerated vesting of restricted stock or similar awards, then by reducing or eliminating any other remaining Total Payments. The preceding provisions of this subsection 8.4.4(a) shall take precedence over the provisions of any other plan, arrangement or agreement governing the Executive’s rights and entitlements to any benefits or compensation.

8.4.5    Change in Control. For purposes of this Agreement, a “Change in Control” has the meaning set forth in the Company’s 2009 Stock Incentive Plan, or its successor, as amended, modified or restated from time to time, provided that if such definition is amended, modified or restated and the resulting definition, or a definition under a successor

plan, is less favorable to the Executive than the definition as of the date hereof, as determined in the reasonable sole discretion of the Company, then the definition as of the date hereof shall be the definition that is used.

9.    Other Agreements. The Executive represents and warrants to the Company that:

10.    Survival of Provisions. Sections 3 (“Other Business Activities”), 6 (“Confidentiality and Proprietary Rights”), 7 (“Covenants”), 8 (“Termination”), and 11 (“General Provisions”) of this Agreement shall survive the termination of the Period of Employment.
