At Will Employment. While we look forward to a long and profitable relationship, you will be an at-will employee of the Company. Any statements or representations to the contrary (and, indeed, any statements contradicting any provision in this letter agreement) should be regarded by you as ineffective. Notwithstanding the at-will nature of your employment, you hereby agree that you will provide two (2) months’ written notice of your intention to terminate your employment with the Company. During any period of your required notice, you will continue to be an employee, and you will continue to be entitled to receive your base salary and any earned but unpaid bonus as of your employment termination date to the extent that the applicable full bonus plan period has been completed as of the employment termination date (notwithstanding any bonus plan terms to the contrary). Your fiduciary duties and other obligations as an employee of the Company will continue, and you will cooperate in the transition of your responsibilities. The Company shall, however, have the right, in its sole discretion, to direct that you no longer come in to work or to shorten the notice period. If the Company shortens the required notice period you have provided, it reserves the right, in its sole discretion, to not pay you for any remaining period of notice. Your participation in any stock option or benefit program is not to be regarded as assuring you of continuing employment for any particular period of time. Although your job duties, title, compensation and benefits, as well as the Company’s personnel policies and procedures, may change from time to time, any modification or change in your at-will employment status may only occur by way of a written employment agreement signed by you and the Chief Executive Officer of the Company.

(a)“Notwithstanding the at-will nature of your employment, if the Company terminates your employment without Cause (as defined above) or you resign your employment and such resignation qualifies as a Constructive Termination (as defined above), but only so long as you sign, and do not revoke, a separation agreement and full and complete release of claims in a form provided to you by the Company (the “Release”):

i.the Company will pay you, following any applicable revocation period, six (6) months of your base salary, paid in the form of salary continuation; provided, however, that any salary continuation payments payable to you under this paragraph will be reduced by any amounts payable to you as notice as may be required by applicable law;

ii.to the extent that you participate in a bonus plan with the Company as of your employment termination date, the Company will pay you, following any applicable revocation period, a bonus amount under such bonus plan which is based on achievement of plan metrics as of your employment termination date, as determined in good faith by the Company, and prorated for the time period of your employment with the Company during the relevant plan period (notwithstanding any bonus plan terms to the contrary); and

iii.upon your timely election to continue existing medical, dental and/or vision benefits under the Consolidated Omnibus Budget Reconciliation Act (“COBRA”), and consistent with the terms of COBRA and the Company’s health insurance plans, the Company will pay the insurance premiums to continue such existing health benefits for six (6) months. You will remain responsible for, and must continue to pay, the portion of premiums, co-payments, etc. that you would have paid had your employment continued. Following such period, you will have the option of continuing COBRA coverage at your own expense for as long as permitted by law.

The Release will be delivered to you by the Company within five (5) business days following your separation. Your entitlement to the above benefits shall be subject to and conditioned upon your execution and return the Release to the Company within the time period specified in the form and the expiration of any rescission period that may be applicable to your executed Release.

(b)The Company may deduct or withhold from any compensation or benefits any applicable federal, state or local tax or employment withholdings or deductions resulting from any payments or benefits provided under this letter agreement or otherwise in connection with your employment. In addition, it is the Company’s intention that all payments or benefits provided under this letter agreement comply with Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), including without limitation the six-month delay for payments of deferred compensation to “key employees” upon separation from service pursuant to Section 409A(a)(2)(B)(i) of the Code (if applicable), and this letter agreement shall be interpreted, administered and operated accordingly. If under this letter agreement an amount is to be paid in installments, each installment shall be treated as a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2)(iii). Notwithstanding anything to the contrary herein, the Company does not guarantee the tax treatment of any payments or benefits under this letter agreement, including without limitation under the Code, federal, state, local or foreign tax laws and regulations. In the event the Deadline is in the taxable year following your termination of employment, any severance payment or deferred compensation payment shall be paid or commence (as applicable) in such subsequent taxable year if required to avoid a violation under Section 409A of the Code.

(c)In the event that any payment or benefit received or to be received by you pursuant to this letter agreement or otherwise (“Payments”) would (i) constitute a “parachute payment” within the meaning of Section 280G of the Code and (ii) but for this subsection (c), be subject to the excise tax imposed by Section 4999 of the Code, any successor provisions, or any comparable federal, state, local or foreign excise tax (“Excise Tax”), then, subject to the

provisions of subsection (b), such Payments shall be either (A) provided in full pursuant to the terms of this Agreement or any other applicable agreement, or (B) provided as to such lesser extent which would result in the Payments being $1.00 less than the amount at which any portion of the Payments would be subject to the Excise Tax (“Reduced Amount”), whichever of the foregoing amounts, taking into account the applicable federal, state, local and foreign income, employment and other taxes and the Excise Tax (including, without limitation, any interest or penalties on such taxes), results in the receipt by you, on an after-tax basis, of the greatest amount of payments and benefits provided for hereunder or otherwise, notwithstanding that all or some portion of such Payments may be subject to the Excise Tax. Unless the Company and you otherwise agree in writing, any determination required under this Section shall be made by independent tax counsel designated by the Company and reasonably acceptable to you (“Independent Tax Counsel”), whose determination shall be conclusive and binding upon you and the Company for all purposes. For purposes of making the calculations required under this Section, Independent Tax Counsel 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; provided that Independent Tax Counsel shall assume that you pay all taxes at the highest marginal rate. The Company and you shall furnish to Independent Tax Counsel such information and documents as Independent Tax Counsel may reasonably request in order to make a determination under this subsection. The Company shall bear all costs that Independent Tax Counsel may reasonably incur in connection with any calculations contemplated by this Section. In the event that subclause (c)(ii)(B) above applies, then based on the information provided to you and the Company by Independent Tax Counsel, you may, in your sole discretion and within thirty (30) days of the date on which you are provided with the information prepared by Independent Tax Counsel, determine which and how much of the Payments (including the accelerated vesting of equity compensation awards) to be otherwise received by you shall be eliminated or reduced (as long as after such determination the value (as calculated by Independent Tax Counsel in accordance with the provisions of Sections 280G and 4999 of the Code) of the amounts payable or distributable to Executive equals the Reduced Amount). If the Internal Revenue Service (the “IRS”) determines that any Payment is subject to the Excise Tax, then subsection (d) below shall apply, and the enforcement of subsection (d) shall be the exclusive remedy to the Company.

(d)If, notwithstanding any reduction described in subsection (c) hereof (or in the absence of any such reduction), the IRS determines that you are liable for the Excise Tax as a result of the receipt of one or more Payments, then you shall be obligated to surrender or pay back to the Company, within one-hundred twenty (120) days after a final IRS determination, an amount of such payments or benefits equal to the “Repayment Amount.” The Repayment Amount with respect to such Payments shall be the smallest such amount, if any, as shall be required to be surrendered or paid to the Company so that your net proceeds with respect to such Payments (after taking into account the payment of the Excise Tax imposed on such Payments) shall be maximized. Notwithstanding the foregoing, the Repayment Amount with respect to such Payments shall be zero (0) if a Repayment Amount of more than zero (0) would not eliminate the Excise Tax imposed on such Payments or if a Repayment Amount of more

than zero would not maximize the net amount received by you from the Payments. If the Excise Tax is not eliminated pursuant to this subsection (d), you shall pay the Excise Tax.

Arbitration. You and PubMatic agree that any and all disputes, claims, or causes of action, in law or equity, arising from or relating to the enforcement, interpretation or scope of this agreement, or your employment or the termination of your employment (collectively, “Claims”), shall be resolved to the fullest extent permitted by law by final, binding, and (to the extent permitted by law) confidential arbitration as provided for below.

The terms and conditions relating to binding arbitration are as follows:

(1)You and PubMatic mutually waive, relinquish, and give up the right to have disputes relating to any Claims decided by a court or jury.

However, the parties agree that, to the fullest extent permitted by law, arbitration shall be the exclusive remedy for the subject matter of such administrative claims.

The arbitrator shall: (a) have the authority to compel adequate discovery for the resolution of all Claims and to award such relief as would otherwise be permitted by law; and (b) issue a written arbitration decision including the arbitrator’s essential findings and conclusions and a statement of the award. Any right of review of the arbitrator’s decision shall be governed by the applicable civil procedure rules.

(6)PubMatic shall pay all of the arbitration fees in excess of the amount of those fees you would have been required to pay if the Claims were decided in a court of law, regardless of whether you or PubMatic is the prevailing party.

(7)You and PubMatic shall be entitled to engage in reasonable discovery, including depositions, interrogatories, requests for production of documents and things, requests for admissions, physical and mental examinations, expert discovery, and the issuance of subpoenas.

(10)Arbitration shall proceed solely on an individual basis without the right for any Claims to be arbitrated on a class action basis or on bases involving claims brought in a purported representative capacity on behalf of others. The

arbitrator’s authority to resolve and make written awards is limited to Claims between you and PubMatic alone. Claims may not be joined or consolidated unless agreed to in writing by all parties. No arbitration award or decision will have any preclusive effect as to issues or claims in any dispute with anyone who is not a named party to the arbitration.

You understand that you agreeing to this arbitration provision is a condition of PubMatic agreeing to enter into this letter agreement. You agree and represent that you have had the opportunity to consult an attorney of your choice to obtain legal advice regarding the import and effect of this arbitration provision. You acknowledge your voluntary agreement to this arbitration provision by signing this letter agreement.

In the event a court of competent jurisdiction rules that one or more of the above terms, conditions, or provisions of this arbitration provision are void or unenforceable, such term(s), condition(s), or provision(s) shall be severed and the remainder of such terms, conditions, or provisions enforced.
