The following Sections 7 and 8 are hereby added immediately following Section 6 of the Offer Letter, and Sections 7, 8, 9 and I 0 of the Offer Letter (and any references to such Sections therein) are hereby deemed to be renumbered Sections 9, 10, II and 12, respectively:

7. Severance Benefits.

7.1 Termination Without Cause or Resignation for Good Reason After a Change in Control. If your employment ends because of a Covered Termination on or within eighteen ( 18) months after a Change in Control, you will be eligible to receive a lump sum cash severance payment in an amount equal to twelve ( 12) months of your then current base salary (ignoring any reduction in salary that forms the basis for a resignation for Good Reason), Jess any applicable withholdings and deductions, and effective as of your termination date, all of your then-outstanding and unvested compensatory equity awards will become vested. Additionally, you will receive 12 months of COBRA benefits starting from your termination date.

7.2 Payment Terms. As a precondition to receiving any severance benefits as provided in this Section 7, you must sign, and allow to become effective by the 60th day following your Separation from Service, a form of release satisfactory to the Company. You must also continue to comply with all your continuing obligations to the Company under this offer letter and your Employee Invention Assignment and Confidentiality Agreement, and must refrain from engaging, directly or indirectly, in any employment or other business activity which competes with the business of the Company.

Section 409A(a)(2)(B)(i) of the Code, then, solely to the extent necessary to avoid the incurrence of the adverse personal tax consequences under Section 409A of the Code, the timing of the severance payments shall be delayed as follows: on the earlier to occur of (i) the date that is six (6) months and one (1) day after your Separation from Service, or (ii) the date of your death (such earlier date, the “Delayed Initial Payment Date”), and the Company (or the successor entity thereto, as applicable) shall (1) pay you a lump sum amount equal to the sum of the severance payments that you would otherwise have received through the Delayed Initial Payment Date but for the delay imposed by this paragraph, and (2) begin paying the balance of the severance payments in accordance with the payment schedule set forth above.

within ninety (90) days after written notice thereof, and your resignation for Good Reason is effective not later than ninety (90) days after the expiration of such cure period.
