Exhibit 10.11

This EMPLOYMENT AGREEMENT (the “Agreement”) is entered into effective October 13, 2020, by and between Sensei Biotherapeutics, Inc. (the “Company”) and Xxxxxxx Xxxx (the “Employee”).

The Company desires to employ the Employee, in the capacity of full-time Chief Business Officer pursuant to the terms of this Agreement and, in connection therewith, to compensate the Employee for Employee’s personal services to the Company; and

The Employee wishes to be employed by the Company and provide personal services to the Company in return for certain compensation.

Accordingly, in consideration of the mutual promises and covenants contained herein, the parties agree to the following:

1. EMPLOYMENT BY THE COMPANY.

1.1 At-Will Employment. Employee shall be employed by the Company on an “at-will” basis, meaning either the Company or Employee may terminate Employee’s employment at any time, with or without cause or advanced notice. Any contrary representations that may have been made to Employee shall be superseded by this Agreement. This Agreement shall constitute the full and complete agreement between Employee and the Company on the “at-will” nature of Employee’s employment with the Company, which may be changed only in an express written agreement signed by Employee and a duly authorized officer of the Company. Employee’s rights to any compensation following a termination shall be only as set forth in Section 6.

1.2 Position. Subject to the terms set forth herein, the Company agrees to employ Employee, initially in the position of Chief Business Officer, and Employee hereby accepts such employment. During the term of Employee’s employment with the Company, Employee will devote Employee’s best efforts and substantially all of Employee’s business time and attention to the business of the Company.

1.3 Start Date. Employee’s employment with the Company shall commence on October 14, 2020, or such other date mutually agreed to in writing by Employee and the Company. The date Employee actually commences working for the Company is referred to as Employee’s “Start Date.” Prior to the Start Date or in the event that Employee does not commence employment with the Company under this Agreement, the Company shall have no obligation to provide Employee with compensation and benefits (including, but not limited to, the “Severance Benefits” stated in Section 6.1).

1.4 Duties. Employee will report to the President and Chief Executive Officer performing such duties as are normally associated with her then current position and such duties as are assigned to her from time to time, subject to the oversight and direction of the President and Chief Executive Officer. In general, and without limitation, Employee will lead all business and corporate development activities. Employee shall perform her duties under this Agreement principally from a remote work location in the San Francisco Bay Area or such other location as assigned. In addition, Employee shall make such business trips to such places as may be necessary or advisable for the efficient operations of the Company.

1.5 Company Policies and Benefits. The employment relationship between the parties shall also be subject to the Company’s personnel policies and procedures as they may be interpreted, adopted, revised or deleted from time to time in the Company’s sole discretion. Employee will be eligible to participate on the same basis as similarly situated employees in the Company’s benefit plans in effect from time to time during her employment. All matters of eligibility for coverage or benefits under any benefit plan shall be determined in accordance with the provisions of such plan. The Company reserves the right to change, alter, or terminate any benefit plan in its sole discretion. Notwithstanding the foregoing, in the event that the terms of this Agreement differ from or are in conflict with the Company’s general employment policies or practices, this Agreement shall control.

1.6 Insurance. While this Agreement is in effect, for actions within the scope of Employee’s employment, the Company will include Employee as an insured at a level comparable to similarly-situated employees at the Company in its Directors and Officers Liability insurance policy in effect from time to time.

2. COMPENSATION.

2.1 Salary. Employee shall initially receive for Employee’s services to be rendered hereunder an initial annualized base salary of $345,000 (“Base Salary”). The Base Salary is subject to review and adjustment from time to time by the Company in its sole discretion. The Base Salary is payable subject to standard federal and state payroll withholding requirements in accordance with the Company’s standard payroll practices.

2.2 Annual Bonus. Employee shall be eligible to receive an annual performance bonus of up to 30% (the “Target Percentage”) of her then-current Base Salary (“Annual Bonus”). The Annual Bonus will be based upon the Company’s assessment of the Employee’s performance, the Company’s attainment of targeted goals as set by the Company’s Board of Directors (the “Board”) in its sole discretion, overall economic conditions and forecasts, and related financial factors, all as determined by the Company in its sole discretion. The Annual Bonus, if any, will be subject to applicable payroll deductions and withholdings. Following the close of each calendar year, the Company will determine whether the Employee has earned the Annual Bonus, and the amount of any Annual Bonus (which can be less than the Target Percentage), based on the set criteria. No amount of the Annual Bonus is guaranteed, and the Employee must be an employee in good standing on the Annual Bonus payment date to be eligible to receive an Annual Bonus; except as stated in this Section 2.2, no partial or prorated bonuses will be provided. Notwithstanding the foregoing, Employee will be eligible to receive a prorated bonus for 2020, calculated with reference to the Start Date. The Employee’s eligibility for an Annual Bonus is subject to change in the discretion of the Board (or any authorized committee thereof).

2.3 Signing and Retention Payment. The Company will make a one-time payment to Employee of $25,000 (the “Signing and Retention Payment”), less applicable withholding taxes, which will be earned upon Employee remaining in employment through the

one (1) year anniversary of the Start Date. The Signing and Retention Payment will be paid as an advance, in a lump sum within fifteen (15) days following Employee’s Start Date, subject to Employee’s continued employment through and including the date on which the Signing and Retention Payment is paid. If at any time prior to the one (1) year anniversary of Employee’s Start Date, Employee’s service to the Company terminates for any reason (other than a termination by the Company without Cause (as defined below) or a resignation by Employee for Good Reason (as defined below)), Employee will be required to, and hereby agrees to, repay to the Signing and Retention Payment (on a net of tax basis) (such amount, the “Repayment Amount”), provided that the Repayment Amount to be paid by Employee will be calculated as follows: for each full month of Employee’s employment with the Company following the Start Date, the Company will forgive one-twelfth (1/12th) of the Repayment Amount, and the remaining unforgiven portion of the Repayment Amount will be due and payable by Employee to the Company on demand. Employee agrees that the Company may deduct, in accordance with applicable law, the Repayment Amount from any payments the Company owes Employee, including but not limited to any regular payroll amount and any expense payments. Employee further agrees to pay to the Company, within thirty (30) days of the termination date, any remaining unpaid balance of the Repayment Amount not covered by such deductions.

2.4 Stock Option. Subject to approval of the Board, Employee will be granted an option to purchase 10,000,000 shares of the Company’s common stock (the “Option”), pursuant and subject to the Company’s 2018 Stock Incentive Plan (the “Plan”) and other documents issued in connection with the grant (the “Option Documents”), at an exercise price per share equal to the fair market value of a share of the Company’s common stock on the date of grant, as determined by the Board in its sole discretion. The vesting commencement date of the Option will be the Start Date (the “Vesting Commencement Date”). The Option will vest according to the following schedule: four-year vesting with 25% of the shares subject to the Option vesting upon the one year anniversary of the Vesting Commencement Date and the balance of the shares vesting in equal installments each month thereafter over the thirty-six (36) month period to follow, subject to Employee being employed by the Company on such dates. The specific terms and conditions of the Option will be as set forth in the Plan, grant notice, option agreement and other applicable documents, which Employee may be required to sign.

2.5 Expense Reimbursement. The Company will reimburse Employee for all reasonable, documented business expenses incurred in connection with her services hereunder, in accordance with the Company’s business expense reimbursement policies and procedures as may be in effect from time to time. For the avoidance of doubt, to the extent that any reimbursements payable to Employee are subject to the provisions of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”): (a) any such reimbursements will be paid 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 will not affect the amount eligible for reimbursement in any subsequent year, and (c) the right to reimbursement under this Agreement will not be subject to liquidation or exchange for another benefit.

3. CONFIDENTIAL INFORMATION AND INVENTIONS OBLIGATIONS. Contemporaneously with this Agreement and as a condition of employment, Employee agrees to sign and abide by the Employee Confidential Information and Inventions Assignment Agreement (the “Confidential Information Agreement”) attached hereto as Exhibit A. The Confidential Information Agreement may be amended by the parties from time to time without regard to this Agreement. The Confidential Information Agreement contains provisions that are intended by the parties to survive and do survive termination or expiration of this Agreement.

4. OUTSIDE ACTIVITIES. Except with the prior written consent of the Company’s Board, Employee will not, while employed by the Company, undertake or engage in any other employment, occupation or business enterprise that would interfere with Employee’s responsibilities and the performance of Employee’s duties hereunder except for (i) reasonable time devoted to volunteer services for or on behalf of such religious, educational, non-profit and/or other charitable organization as Employee may wish to serve; (ii) reasonable time devoted to activities in the non-profit and business communities consistent with Employee’s duties; (iii) Employee’s participation in professional and academic activities; (iv) the activity stated in Exhibit B, provided that such activity does not interfere with Employee’s full performance of duties under this Agreement and does not pose a conflict of interest in the determination of the President and Chief Executive Officer; and (v) such other activities as may be specifically approved by the Board. This restriction shall not, however, preclude Employee from managing personal investments or owning less than one percent (1%) of the total outstanding shares of a publicly-traded company.

5. NO CONFLICT WITH EXISTING OBLIGATIONS. Employee represents that Employee’s performance of all the terms of this Agreement and as an Employee of the Company do not and will not breach any agreement or obligation of any kind made prior to Employee’s employment by the Company, including agreements or obligations Employee may have with prior employers or entities for which Employee has provided services. Employee has not entered into, and Employee agrees that Employee will not enter into, any agreement or obligation, either written or oral, in conflict herewith.

6. TERMINATION OF EMPLOYMENT. The parties acknowledge that Employee’s employment relationship with the Company is at-will. Either Employee or the Company may terminate the employment relationship at any time, with or without Cause. The provisions in this Section govern the amount of compensation, if any, to be provided to Employee upon termination of employment and do not alter this at-will status.

6.1 Termination by the Company Without Cause or Resignation by Employee for Good Reason.

(a) The Company shall have the right to terminate Employee’s employment with the Company pursuant to this Section 6.1 at any time without “Cause” (as defined in Section 6.2(a) below) by giving notice as described in Section 6.6 of this Agreement. A termination pursuant to Section 6.4 or 6.5 below is not a termination without “Cause” for purposes of receiving the Severance Benefits described in (and as defined in) this Section 6.1.

(b) If the Company terminates Employee’s employment at any time without Cause or Employee terminates her employment with the Company for “Good Reason” (as defined in Section 6.1(g) below), then Employee shall be entitled to receive the Accrued Obligations (defined in 6.1(d) below). If such termination without Cause constitutes a “separation from service” (as defined under Treasury Regulation Section 1.409A-1(h), without regard to any alternative definition thereunder, a “Separation from Service”), and Employee complies with the obligations in Section 6.1(c) below, Employee shall also be eligible to receive the following “Severance Benefits”:

(i) The Company will pay Employee an amount equal to Employee’s then current Base Salary for six (6) months, less all applicable withholdings and deductions (“Severance”), paid in equal installments beginning on the Company’s first regularly scheduled payroll date following the Release Effective Date (as defined in Section 6.1(c) below), with the remaining installments occurring on the Company’s regularly scheduled payroll dates thereafter.

(ii) If Employee timely elects continued coverage under COBRA, or state continuation coverage (as applicable), for herself and her covered dependents under the Company’s group health plans following such termination, then the Company shall pay the portion of the COBRA, or state continuation coverage, premiums, which is equal to the cost of the coverage that the Company was paying as of the date of termination, necessary to continue Employee’s and her covered dependents’ health insurance coverage in effect for herself (and her covered dependents) on the termination date until the earliest of: (i) six (6) months following the termination date; (ii) the date when Employee becomes eligible for substantially equivalent health insurance coverage in connection with new employment or self-employment; or (iii) the date Employee ceases to be eligible for COBRA continuation coverage for any reason, including plan termination (such period from the termination date through the earlier of (i)-(iii), (the “COBRA Payment Period”). Notwithstanding the foregoing, if at any time the Company determines that its payment of COBRA, or state continuation coverage, premiums on Employee’s behalf would result in a violation of applicable law (including, but not limited to, the 2010 Patient Protection and Affordable Care Act, as amended by the 2010 Health Care and Education Reconciliation Act), then in lieu of paying such portion of the premiums pursuant to this Section, the Company shall pay Employee on the last day of each remaining month of the COBRA Payment Period, a fully taxable cash payment equal to the portion of such COBRA or state continuation coverage premium that would have been paid by the Company for such month, subject to applicable tax withholding, for the remainder of the COBRA Payment Period. Nothing in this Agreement shall deprive Employee of her rights under COBRA or ERISA for benefits under plans and policies arising under her employment by the Company.

(iii) Notwithstanding the terms of any equity plan or award agreement to the contrary, the unvested portion of all time-based equity awards outstanding on the date of Employee’s termination that would have vested over the six (6) month period following the date of Employee’s termination had she remained continuously employed by the Company during such period will be automatically vested and exercisable as of the Separation Date (as defined below). Notwithstanding the foregoing, in the event that such termination without Cause or resignation for Good Reason under this Section 6.1 occurs within twelve (12) months following the effective date of a Change in Control (as defined in the Plan), and provided that such termination without Cause constitutes a Separation from Service, and subject to Employee’s full compliance with Section 6.1(c), then, effective as of Employee’s date of termination, each of Employee’s then outstanding options and equity awards that have been continued, assumed or substituted for by the Company or the surviving entity or acquirer in such Change in Control, including awards that would otherwise vest only upon satisfaction of performance criteria, shall

accelerate and become vested and exercisable as to 100% of the then-unvested and, in the case of performance-based awards, then-unearned (at the actual performance level or, if the actual performance level has not been determined at the time of such termination, at 100% achievement of target, in any case, unless more-favorable acceleration terms are otherwise provided in the award agreement applicable to such performance-based award) shares subject to the equity award.

(c) Employee will be paid all of the Accrued Obligations on the Company’s first payroll date after Employee’s date of termination from employment or earlier if required by law. Employee shall receive the Severance Benefits pursuant to Section 6.1(b) of this Agreement if: (i) by the 60th day following the date of Employee’s Separation from Service, she has signed and delivered to the Company a separation agreement containing an effective, general release of claims in favor of the Company and its affiliates and representatives, in the form presented by the Company (the “Release”), which cannot be revoked in whole or part by such date (the date that the Release can no longer be revoked is referred to as the “Release Effective Date”); and (ii) if she holds any other positions with the Company or any Affiliate, including a position on the Board, she resigns such position(s) to be effective no later than the date of Employee’s termination date (or such other date as requested by the Board); (iii) she returns all Company property; (iv) she complies with her post-termination obligations under this Agreement and the Confidential Information Agreement; and (v) she complies with the terms of the Release, including without limitation any non-disparagement and confidentiality provisions contained in Release. To the extent that any severance payments are deferred compensation under Section 409A of the Code, and are not otherwise exempt from the application of Section 409A, then, if the period during which Employee may consider and sign the Release spans two calendar years, the payment of Severance will not be made or begin until the later calendar year.

(d) For purposes of this Agreement, “Accrued Obligations” are (i) Employee’s accrued but unpaid salary and accrued but unused vacation days, each through the date of termination, (ii) any unreimbursed business expenses incurred by Employee payable in accordance with the Company’s standard expense reimbursement policies, and (iii) benefits owed to Employee under any qualified retirement plan or health and welfare benefit plan in which Employee was a participant in accordance with applicable law and the provisions of such plan.

(e) The Severance Benefits provided to Employee pursuant to this Section 6.1 are in lieu of, and not in addition to, any benefits to which Employee may otherwise be entitled under any Company severance plan, policy, program, or prior agreement with the Company.

(f) Any damages caused by the termination of Employee’s employment without Cause would be difficult to ascertain; therefore, the Severance Benefits for which Employee is eligible pursuant to Section 6.1(b) above in exchange for the Release is agreed to by the parties as liquidated damages, to serve as full compensation, and not a penalty.

(g) For purposes of this Agreement, “Good Reason” shall mean the occurrence of any of the following events without Employee’s consent: (i) a material reduction in Employee’s Base Salary of at least 10%; (ii) a material reduction in Employee’s duties, authority and responsibilities relative to Employee’s duties, authority, and responsibilities in effect immediately prior to such reduction; (iii) the relocation of Employee’s principal place of

employment, without Employee’s consent, in a manner that lengthens her one-way commute distance by fifty (50) or more miles from her then-current principal place of employment immediately prior to such relocation; or (iv) any material breach of this Agreement by Company; provided, however, that, any such termination by Employee shall only be deemed for Good Reason pursuant to this definition if: (1) Employee gives the Company written notice of her intent to terminate for Good Reason within thirty (30) days following the first occurrence of the condition(s) that she believes constitute(s) Good Reason, which notice shall describe such condition(s); (2) the Company fails to remedy such condition(s) within thirty (30) days following receipt of the written notice (the “Cure Period”); (3) the Company has not, prior to receiving such notice from Employee, already informed Employee that her employment with the Company is being terminated; and (4) Employee voluntarily terminates her employment within thirty (30) days following the end of the Cure Period.

6.2 Termination by the Company for Cause.

(a) Subject to Section 6.2(b) below, the Company shall have the right to terminate Employee’s employment with the Company at any time for Cause by giving notice as described in Section 6.6 of this Agreement.

(b) “Cause” for termination shall mean that the Company has determined in its sole discretion that Employee has engaged in any of the following: (i) a material breach of any covenant or condition under this Agreement or any other agreement between the parties; (ii) any act constituting dishonesty, fraud, immoral or disreputable conduct; (iii) any conduct which constitutes a felony under applicable law; (iv) material violation of any Company policy or any act of misconduct; (v) refusal to follow or implement a clear and reasonable directive of the Company; (vi) negligence or incompetence in the performance of Employee’s duties after the expiration of ten (10) days without cure after written notice of such failure; or (vii) breach of fiduciary duty.

(c) In the event Employee’s employment is terminated at any time for Cause, Employee will not receive the Severance Benefits, or any other severance compensation or benefit, except that, consistent with the Company’s standard payroll policies, the Company shall provide to Employee the Accrued Obligations.

6.3 Resignation by the Employee (other than for Good Reason).

(a) Employee may resign for any reason from Employee’s employment with the Company at any time by giving notice as described in Section 6.6.

(b) In the event Employee resigns from Employee’s employment with the Company (other than for Good Reason), Employee will not receive the Severance Benefits, or any other severance compensation or benefit, except that, consistent with the Company’s standard payroll policies, the Company shall provide to Employee the Accrued Obligations.

6.4 Termination by Virtue of Death or Disability of the Employee.

(a) In the event of Employee’s death while employed pursuant to this Agreement, all obligations of the parties hereunder shall terminate immediately, and the Company shall, pursuant to the Company’s standard payroll policies, provide to Employee’s legal representatives Employee’s Accrued Obligations, but neither Employee nor her legal representatives will be eligible for the Severance Benefits.

(b) Subject to applicable state and federal law, the Company shall at all times have the right, upon written notice to the Employee, to terminate this Agreement based on the Employee’s Disability (as defined below). Termination by the Company of the Employee’s employment based on “Disability” shall mean termination because the Employee is unable due to a physical or mental condition to perform the essential functions of her position with or without reasonable accommodation for six (6) months in the aggregate during any twelve (12) month period or based on the written certification by two licensed physicians of the likely continuation of such condition for such period. This definition shall be interpreted and applied consistent with the Americans with Disabilities Act, the Family and Medical Leave Act, and other applicable law. In the event Employee’s employment is terminated based on the Employee’s Disability, Employee will not receive the Severance Benefits, or any other severance compensation or benefit, except that, pursuant to the Company’s standard payroll policies, the Company shall provide to Employee the Accrued Obligations.

6.5 Termination Due to Discontinuance of Business. Anything in this Agreement to the contrary notwithstanding, in the event the Company’s business is discontinued because rendered impracticable by substantial financial losses, lack of funding, legal decisions, administrative rulings, declaration of war, dissolution, national or local economic depression or crisis or any reasons beyond the control of the Company, then this Agreement shall terminate as of the day the Company determines to cease operation with the same force and effect as if such day of the month were originally set as the termination date hereof. In the event this Agreement is terminated pursuant to this Section 6.5, Employee will not receive the Severance Benefits, or any other severance compensation or benefit, except that, pursuant to the Company’s standard payroll policies, the Company shall provide to Employee the Accrued Obligations.

6.6 Notice; Effective Date of Termination.

(a) Termination of Employee’s employment (the “Separation Date”) pursuant to this Agreement shall be effective on the earliest of:

(i) immediately after the Company gives notice to Employee of Employee’s termination, with or without Cause, unless pursuant to Section 6.2(b)(vi) in which case ten (10) days after notice if not cured, or unless the Company specifies a later date, in which case, termination shall be effective as of such later date;

(ii) immediately upon the Employee’s death;

(iii) immediately after the Company gives written notice to Employee of Employee’s termination on account of Employee’s Disability, unless the Company specifies a later Separation Date, in which case, termination shall be effective as of such later Separation Date, provided that Employee has not returned to the full time performance of Employee’s duties prior to such date;

(iv) forty-five (45) days (or such shorter period agreed to by the President and Chief Executive Officer and the Employee in writing) after the Employee gives written notice to the Company of Employee’s resignation for any reason, provided that the Company may set a Separation Date at any time between the date of notice and the date of resignation, in which case the Employee’s resignation shall be effective as of such other date. Employee will receive compensation through any required notice period; or

(v) for a termination for Good Reason, immediately upon Employee’s full satisfaction of the requirements of Section 6.1(g).

(b) In the event notice of a termination under subsection (a)(i) is given orally, at the other party’s request, the party giving notice must provide written confirmation of such notice within five (5) business days of the request in compliance with the requirement of Section 7.1 below. In the event of a termination for Cause, written confirmation shall specify the subsection(s) of the definition of Cause relied on to support the decision to terminate.

6.7 Cooperation With Company After Termination of Employment. Following termination of Employee’s employment for any reason, Employee shall reasonably cooperate with the Company in all matters relating to the winding up of Employee’s pending work including, but not limited to, any litigation in which the Company is involved, and the orderly transfer of any such pending work to such other employees as may be designated by the Company.

6.8 Effect of Termination. Employee agrees that should Employee’s employment be terminated for any reason, Employee shall be deemed to have resigned from any and all positions with the Company and its subsidiaries.

6.9 Application of Section 409A. Notwithstanding anything to the contrary set forth herein, any payments and benefits provided under this Agreement that constitute “deferred compensation” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (“Code”) and the regulations and other guidance thereunder and any state law of similar effect (collectively, “Section 409A”) shall not commence in connection with Employee’s termination of employment unless and until Employee has also incurred a Separation from Service, unless the Company reasonably determines that such amounts may be provided to Employee without causing Employee to incur the additional 20% tax under Section 409A. It is intended that each installment of severance pay provided for in this Agreement is a separate “payment” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i). For the avoidance of doubt, it is intended that severance payments set forth in this Agreement satisfy, to the greatest extent possible, the exceptions from the application of Section 409A provided under Treasury Regulation Sections 1.409A-1(b)(4) and 1.409A-1(b)(9). If the Company (or, if applicable, the successor entity thereto) determines that any payments or benefits constitute “deferred compensation” under Section 409A and Employee is, on the termination of service, a “specified employee” of the Company or any successor entity thereto, as such term is defined in 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, the timing of the payments and benefits shall be delayed until the earlier to occur of: (a) the date that is six months and one day after Employee’s Separation From Service, or (b) the date of Employee’s death (such applicable date, the “Specified Employee Initial Payment Date”). On the Specified Employee Initial Payment Date, the Company (or the

successor entity thereto, as applicable) shall (i) pay to Employee a lump sum amount equal to the sum of the payments and benefits that Employee would otherwise have received through the Specified Employee Initial Payment Date if the commencement of the payment of such amounts had not been so delayed pursuant to this Section and (ii) commence paying the balance of the payments and benefits in accordance with the applicable payment schedules set forth in this Agreement. All reimbursements provided under this Agreement shall be subject to the following requirements: (i) the amount of in-kind benefits provided or reimbursable expenses incurred in one taxable year shall not affect the in-kind benefits to be provided or the expenses eligible for reimbursement in any other taxable year, (ii) all reimbursements shall be paid as soon as administratively practicable, but in no event shall any reimbursement be paid after the last day of the taxable year following the taxable year in which the expense was incurred, and (iii) the right to reimbursement or in-kind benefits is not subject to liquidation or exchange for any other benefit. It is intended that all payments and benefits under this Agreement shall either comply with or be exempt from the requirements of Section 409A, and any ambiguity contained herein shall be interpreted in such manner so as to avoid adverse personal tax consequences under Section 409A. Notwithstanding the foregoing, the Company shall in no event be obligated to indemnify Employee for any taxes or interest that may be assessed by the Internal Revenue Service pursuant to Section 409A of the Code to payments made pursuant to this Agreement.

7. GENERAL PROVISIONS.

7.1 Notices. Any notices required hereunder to be in writing shall be deemed effectively given: (a) upon personal delivery to the party to be notified, (b) when sent by electronic mail, telex or confirmed facsimile if sent during normal business hours of the recipient, and if not, then on the next business day, (c) five (5) days after having been sent by registered or certified mail, return receipt requested, postage prepaid, or (d) one (1) day after deposit with a nationally recognized overnight courier, specifying next day delivery, with written verification of receipt. All communications shall be sent to the Company at its primary office location and to Employee at Employee’s address as listed on the Company payroll or Employee’s company-provided email address, or at such other address as the Company or the Employee may designate by ten (10) days advance written notice to the other.

7.2 Severability. Whenever possible, each provision of this Agreement will be interpreted in such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provisions had never been contained herein.

7.3 Waiver. If either party should waive any breach of any provisions of this Agreement, Employee or it shall not thereby be deemed to have waived any preceding or succeeding breach of the same or any other provision of this Agreement.

7.4 Complete Agreement. This Agreement constitutes the entire agreement between Employee and the Company with regard to the subject matter hereof. This Agreement is the complete, final, and exclusive embodiment of their agreement with regard to this subject matter

and supersedes any prior oral discussions or written communications and agreements, including the “Term Sheet” from the Company dated September 3, 2020. This Agreement is entered into without reliance on any promise or representation other than those expressly contained herein, and it cannot be modified or amended except in writing signed by Employee and an authorized officer of the Company. The parties have entered into a separate Confidential Information Agreement and may enter into separate agreements related to equity awards. These separate agreements govern other aspects of the relationship between the parties, have or may have provisions that survive termination of the Employee’s employment under this Agreement, may be amended or superseded by the parties without regard to this Agreement and are enforceable according to their terms without regard to the enforcement provision of this Agreement.

7.5 Counterparts. This Agreement may be executed in separate counterparts, any one of which need not contain signatures of more than one party, but all of which taken together will constitute one and the same Agreement.

7.6 Headings. The headings of the sections hereof are inserted for convenience only and shall not be deemed to constitute a part hereof nor to affect the meaning thereof.

7.7 Successors and Assigns. The Company shall assign this Agreement and its rights and obligations hereunder in whole, but not in part, to any Company or other entity with or into which the Company may hereafter merge or consolidate or to which the Company may transfer all or substantially all of its assets, if in any such case said Company or other entity shall by operation of law or expressly in writing assume all obligations of the Company hereunder as fully as if it had been originally made a party hereto, but may not otherwise assign this Agreement or its rights and obligations hereunder. The Employee may not assign or transfer this Agreement or any rights or obligations hereunder, other than to her estate upon her death.

7.8 Choice of Law. All questions concerning the construction, validity and interpretation of this Agreement will be governed by the law of the State of California.

7.9 Resolution of Disputes. To ensure the rapid and economical resolution of disputes that may arise in connection with Employee’s employment with the Company, Employee and the Company agree that any and all disputes, claims, or causes of action, in law or equity, including but not limited to statutory claims, arising from or relating to the enforcement, breach, performance, or interpretation of this Agreement, Employee’s employment with the Company, or the termination of Employee’s employment, shall be resolved pursuant to the Federal Arbitration Act, 9 U.S.C. § 1-16, to the fullest extent permitted by law, by final, binding and confidential arbitration, before a single arbitrator, conducted by JAMS or its successor, under JAMS’ then applicable Employment Arbitration Rules and Procedures (available upon request and also currently available at xxxx://xxx.xxxxxxx.xxx/xxxxx-xxxxxxxxxx-xxxxxxxxxxx/) and subject to JAMS’ then applicable Policy on Employment Arbitration Minimum Standards of Procedural Fairness. Employee acknowledges that by agreeing to this arbitration procedure, both Employee and the Company waive the right to resolve any such dispute through a trial by jury or judge or administrative proceeding. In addition, all claims, disputes, or causes of action under this Section, whether by Employee or the Company, must be brought in an individual capacity, and shall not be brought as a plaintiff (or claimant) or class member in any purported class or representative proceeding, nor joined or consolidated with the claims of any other person

or entity. The arbitrator may not consolidate the claims of more than one person or entity, and may not preside over any form of representative or class proceeding. To the extent that the preceding sentences regarding class claims or proceedings are found to violate applicable law or are otherwise found unenforceable, any claim(s) alleged or brought on behalf of a class shall proceed in a court of law rather than by arbitration. This paragraph shall not apply to any action or claim that cannot be subject to mandatory arbitration as a matter of law, including, without limitation, claims brought pursuant to the California Private Attorneys General Act of 2004, as amended, the California Fair Employment and Housing Act, as amended, and the California Labor Code, as amended, to the extent such claims are not permitted by applicable law(s) to be submitted to mandatory arbitration and the applicable law(s) are not preempted by the Federal Arbitration Act or otherwise invalid (collectively, the “Excluded Claims”). In the event Employee intends to bring multiple claims, including one of the Excluded Claims listed above, the Excluded Claims may be filed with a court, while any other claims will remain subject to mandatory arbitration. Employee will have the right to be represented by legal counsel at any arbitration proceeding. Questions of whether a claim is subject to arbitration under this agreement shall be decided by the arbitrator. Likewise, procedural questions which grow out of the dispute and bear on the final disposition are also matters for the arbitrator. The arbitrator shall: (a) have the authority to compel adequate discovery for the resolution of the dispute and to award such relief as would otherwise be permitted by law; and (b) issue a written statement signed by the arbitrator regarding the disposition of each claim and the relief, if any, awarded as to each claim, the reasons for the award, and the arbitrator’s essential findings and conclusions on which the award is based. The arbitrator shall be authorized to award all relief that Employee or the Company would be entitled to seek in a court of law. The Company shall pay all JAMS arbitration fees in excess of the administrative fees that Employee would be required to pay if the dispute were decided in a court of law. Nothing in this letter agreement is intended to prevent either Employee or the Company from obtaining injunctive relief in court to prevent irreparable harm pending the conclusion of any such arbitration. Any awards or orders in such arbitrations may be entered and enforced as judgments in the federal and state courts of any competent jurisdiction.

IN WITNESS WHEREOF, the parties have executed this Employment Agreement on the day and year first written above.

EMPLOYEE CONFIDENTIAL INFORMATION AND INVENTIONS ASSIGNMENT AGREEMENT

A-1

For California Employees

EMPLOYEE CONFIDENTIAL INFORMATION AND INVENTIONS ASSIGNMENT AGREEMENT

In consideration of my employment or continued employment by Sensei Biotherapeutics, Inc. (“Employer”), and its subsidiaries, parents, affiliates, successors and assigns (together with Employer, “Company”), the compensation paid to me now and during my employment with Company, and Company’s agreement to provide me with access to its Confidential Information (as defined below), I enter into this Employee Confidential Information and Inventions Assignment Agreement with Employer (the “Agreement”). Accordingly, in consideration of the mutual promises and covenants contained herein, Employer (on behalf of itself and Company) and I agree as follows:

1. Confidential Information Protections.

1.1 Recognition of Company’s Rights; Nondisclosure. My employment by Company creates a relationship of confidence and trust with respect to Confidential Information (as defined below) and Company has a protectable interest in the Confidential Information. At all times during and after my employment, I will hold in confidence and will not disclose, use, lecture upon, or publish any Confidential Information, except as required in connection with my work for Company, or as approved by an officer of Company. I will obtain written approval by an officer of Company before I lecture on or submit for publication any material (written, oral, or otherwise) that discloses and/or incorporates any Confidential Information. I will take all reasonable precautions to prevent the disclosure of Confidential Information. Notwithstanding the foregoing, pursuant to 18 U.S.C. Section 1833(b), I will not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that: (1) is made in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney, and solely for the purpose of reporting or investigating a suspected violation of law; or (2) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. I agree that Company information or documentation to which I have access during my employment, regardless of whether it contains Confidential Information, is the property of Company and cannot be downloaded or retained for my personal use or for any use that is outside the scope of my duties for Company.

1.2 Confidential Information. “Confidential Information” means any and all confidential knowledge or data of Company, and includes any confidential knowledge or data that Company has received, or receives in the future, from third parties that Company has agreed to treat as confidential and to use for only certain limited purposes. By way of illustration but not limitation, Confidential Information includes (a) trade secrets, inventions, ideas, processes, formulas, software in source or object code, data, technology, know-how, designs and techniques, and any other work product of any nature, and all Intellectual Property Rights (defined below) in all of the foregoing (collectively, “Inventions”), including all Company Inventions (defined in Section 2.1); (b) information regarding research, development, new products, business and operational plans, budgets, unpublished financial statements and projections, costs, margins, discounts, credit terms, pricing, quoting procedures, future plans and strategies, capital-raising plans, internal services, suppliers and supplier information; (c) information about customers and potential customers of Company, including customer lists, names, representatives, their needs or desires with respect to the types of products or services offered by Company, and other non-public information; (d) information about Company’s business partners and their services, including names, representatives, proposals, bids, contracts, and the products and services they provide; (e) information regarding personnel, employee lists, compensation, and employee skills; and (f) any other non-public information that a competitor of Company could use to Company’s competitive disadvantage. However, Company agrees that I am free to use information that I knew prior to my employment with Company or that is, at the time of use, generally known in the trade or industry through no breach of this Agreement by me. Company further agrees that this Agreement does not limit my right to discuss my employment or unlawful acts in Company’s workplace, including but not limited to sexual harassment, or report possible violations of law or regulation with any federal, state or local government agency, or to discuss the terms and conditions of my employment with others to the extent expressly permitted by Section 7 of the National Labor Relations Act, or to the extent that such disclosure is protected under the applicable provisions of law or regulation, including but not limited to “whistleblower” statutes or other similar provisions that protect such disclosure, to the extent any such rights are not permitted by applicable law to be the subject of nondisclosure obligations.

1.3 Term of Nondisclosure Restrictions. I will only use or disclose Confidential Information as provided in this Section 1 and I agree that the restrictions in Section 1.1 are intended to continue indefinitely, even after my employment by Company ends. However, if a time limitation on my obligation not to use or disclose Confidential Information is required under applicable law, and the Agreement or its restriction(s) cannot otherwise be enforced, Company and I agree that the two year period after the date my employment ends will be the time limitation relevant to the contested restriction; provided, however, that my obligation not to disclose or use trade secrets that are protected without time limitation under applicable law shall continue indefinitely.

1.4 No Improper Use of Information of Prior Employers and Others. During my employment by Company, I will not improperly use or disclose confidential information or trade secrets, if any, of any former employer or any other person to whom I have an obligation of confidentiality, and I will not bring onto Company’s premises any unpublished documents or property belonging to a former employer or any other person to whom I have an obligation of confidentiality unless that former employer or person has consented in writing.

2. Assignments of Inventions.

2.1 Definitions. The term (a) “Intellectual Property Rights” means all past, present and future rights of the following types, which may exist or be created under the laws of any jurisdiction in the world: trade secrets, Copyrights, trademark and trade name rights, mask work rights, patents and industrial property, and all proprietary rights in technology or works of authorship (including, in each case, any application for any such rights and any rights to apply for any such rights, as well as all rights to pursue remedies for infringement or violation of any such rights); (b) “Copyright” means the exclusive legal right to reproduce, perform, display, distribute and make derivative works of a work of authorship (for example, a literary, musical, or artistic work) recognized by the laws of any jurisdiction in the world; (c) “Moral Rights” means all paternity, integrity, disclosure, withdrawal, special and similar rights recognized by the laws of any jurisdiction in the world; and (d) “Company Inventions” means any and all Inventions (and all Intellectual Property Rights related to Inventions) that are made, conceived, developed, prepared, produced, authored, edited, amended, reduced to practice, or learned or set out in any tangible medium of expression or otherwise created, in whole or in part, by me, either alone or with others, during my employment by Company, and all printed, physical, and electronic copies, and other tangible embodiments of Inventions.

2.2 California Limited Exclusion Notification.

(a) I acknowledge that California Labor Code section 2870(a) provides that I cannot be required to assign to Company any Invention that I develop entirely on my own time without using Company’s equipment, supplies, facilities or trade secret information, except for Inventions that either (i) relate at the time of conception or reduction to practice to Company’s business, or actual or demonstrably anticipated research or development, or (ii) result from any work performed by me for Company (“Nonassignable Inventions”).

(b) To the extent that a provision in this Agreement purports to require me to assign a Nonassignable Invention to Company, the provision is against the public policy of the state of California and is unenforceable.

(c) This limited exclusion does not apply to any patent or Invention covered by a contract between Company and the United States or any of its agencies requiring full title to such patent or Invention to be in the United States.

2.3 Prior Inventions.

(a) On the signature page to this Agreement is a list describing any Inventions that (i) are owned by me or in which I have an interest and that were made or acquired by me prior to my date of first employment by Company, and (ii) may relate to Company’s business or actual or demonstrably anticipated research or development, and (iii) are not to be assigned to Company (“Prior Inventions”). If no such list is attached, I represent and warrant that no Inventions that would be classified as Prior Inventions exist as of the date of this Agreement.

Employee Confidential Information and Inventions Assignment Agreement

Page 2

(b) I agree that if I use any Prior Inventions and/or Nonassignable Inventions in the scope of my employment, or if I include any Prior Inventions and/or Nonassignable Inventions in any product or service of Company, or if my rights in any Prior Inventions and/or any Nonassignable Inventions may block or interfere with, or may otherwise be required for, the exercise by Company of any rights assigned to Company under this Agreement (each, a “License Event”), (i) I will immediately notify Company in writing, and (ii) unless Company and I agree otherwise in writing, I hereby grant to Company a non-exclusive, perpetual, transferable, fully-paid, royalty-free, irrevocable, worldwide license, with rights to sublicense through multiple levels of sublicensees, to reproduce, make derivative works of, distribute, publicly perform, and publicly display in any form or medium (whether now known or later developed), make, have made, use, sell, import, offer for sale, and exercise any and all present or future rights in, such Prior Inventions and/or Nonassignable Inventions. To the extent that any third parties have any rights in or to any Prior Inventions or any Nonassignable Inventions, I represent and warrant that such third party or parties have validly and irrevocably granted to me the right to grant the license stated above. For purposes of this paragraph, “Prior Inventions” includes any Inventions that would be classified as Prior Inventions, whether or not they are listed on the signature page to this Agreement.

2.4 Assignment of Company Inventions. I hereby assign to Employer all my right, title, and interest in and to any and all Company Inventions other than Nonassignable Inventions and agree that such assignment includes an assignment of all Moral Rights. To the extent such Moral Rights cannot be assigned to Employer and to the extent the following is allowed by the laws in any country where Moral Rights exist, I hereby unconditionally and irrevocably waive the enforcement of such Moral Rights, and all claims and causes of action of any kind against Employer or related to Employer’s customers, with respect to such rights. I further agree that neither my successors-in-interest nor legal heirs retain any Moral Rights in any Company Inventions. Nothing contained in this Agreement may be construed to reduce or limit Company’s rights, title, or interest in any Company Inventions so as to be less in any respect than that Company would have had in the absence of this Agreement.

2.5 Obligation to Keep Company Informed. During my employment by Company, I will promptly and fully disclose to Company in writing all Inventions that I author, conceive, or reduce to practice, either alone or jointly with others. At the time of each disclosure, I will advise Company in writing of any Inventions that I believe constitute Nonassignable Inventions; and I will at that time provide to Company in writing all evidence necessary to substantiate my belief. Subject to Section 2.3(b), Company agrees to keep in confidence, not use for any purpose, and not disclose to third parties without my consent, any confidential information relating to Nonassignable Inventions that I disclose in writing to Company.

2.6 Government or Third Party. I agree that, as directed by Company, I will assign to a third party, including without limitation the United States, all my right, title, and interest in and to any particular Company Invention.

2.7 Ownership of Work Product. I acknowledge that all original works of authorship that are made by me (solely or jointly with others) within the scope of my employment and that are protectable by Copyright are “works made for hire,” pursuant to United States Copyright Act (17 U.S.C., Section 101).

2.8 Enforcement of Intellectual Property Rights and Assistance. I will assist Company, in every way Company requests, including signing, verifying and delivering any documents and performing any other acts, to obtain and enforce United States and foreign Intellectual Property Rights and Moral Rights relating to Company Inventions in any jurisdictions in the world. My obligation to assist Company with respect to Intellectual Property Rights relating to Company Inventions will continue beyond the termination of my employment, but Company will compensate me at a reasonable rate after such termination for the time I actually spend on such assistance. If Company is unable for any reason, after reasonable effort, to secure my signature on any document needed in connection with the actions specified in this paragraph, I hereby irrevocably designate and appoint Employer and its duly authorized officers and agents as my agent and attorney in fact, which appointment is coupled with an interest, to act for and on my behalf to execute, verify and file any such documents and to do all other lawfully permitted acts to further the purposes of this Agreement with the same legal force and effect as if executed by me. I hereby waive and quitclaim to Company any and all claims, of any nature whatsoever, which I now or may hereafter have for infringement of any Intellectual Property Rights assigned to Employer under this Agreement.

2.9 Incorporation of Software Code. I agree not to incorporate into any Inventions, including any Company software, or otherwise deliver to Company, any software code licensed under the GNU General Public License, Lesser General Public License, or any other license that, by its terms, requires or conditions the use or distribution of such code on the disclosure, licensing, or distribution of any source code owned or licensed by Company, except in strict compliance with Company’s policies regarding the use of such software or as directed by Company.

3. Records. I agree to keep and maintain adequate and current records (in the form of notes, sketches, drawings and in any other form that is required by Company) of all Confidential Information developed by me and all Company Inventions made by me during the period of my employment at Company, which records will be available to and remain the sole property of Employer at all times.

4. Duty of Loyalty During Employment. During my employment by Company, I will not, without Company’s written consent, directly or indirectly engage in any employment or business activity that is directly or indirectly competitive with, or would otherwise conflict with, my employment by Company.

5. No Solicitation of Employees, Consultants or Contractors. To the extent permitted by applicable law, I agree that during my employment and for the one year period after the date my employment ends for any reason, including but not limited to voluntary termination by me or involuntary termination by Company, I will not, as an officer, director, employee, consultant, owner, partner, or in any other capacity, either directly or through others (except on behalf of Company) solicit, induce, encourage any person known to me to be an employee, consultant, or independent contractor of Company to terminate his, her or its relationship with Company.

6. Reasonableness of Restrictions. I have read this entire Agreement and understand it. I agree that (a) this Agreement does not prevent me from earning a living or pursuing my career, and (b) the restrictions contained in this Agreement are reasonable, proper, and necessitated by Company’s legitimate business interests. I represent and agree that I am entering into this Agreement freely, with knowledge of its contents and the intent to be bound by its terms. If a court finds this Agreement, or any of its restrictions, are ambiguous, unenforceable, or invalid, Company and I agree that the court will read the Agreement as a whole and interpret such restriction(s) to be enforceable and valid to the maximum extent allowed by law. If the court declines to enforce this Agreement in the manner provided in this Section and/or Section 12.2, Company and I agree that this Agreement will be automatically modified to provide Company with the maximum protection of its business interests allowed by law, and I agree to be bound by this Agreement as modified.

7. No Conflicting Agreement or Obligation. I represent that my performance of all the terms of this Agreement and as an employee of Company does not and will not breach any agreement to keep in confidence information acquired by me in confidence or in trust prior to my employment by Company. I have not entered into, and I agree I will not enter into, any written or oral agreement in conflict with this Agreement.

8. Return of Company Property. When I cease to be employed by Company, I will deliver to Company any and all materials, together with all copies thereof, containing or disclosing any Company Inventions, or Confidential Information. I will not copy, delete, or alter any information contained upon my Company computer or Company equipment before I return it to Company. In addition, if I have used any personal computer, server, or e-mail system to receive, store, review, prepare or transmit any Company information, including but not limited to, Confidential Information, I agree to provide Company with a computer-useable copy of all such information and then permanently delete such information from those systems; and I agree to provide Company access to my system as reasonably requested to verify that the necessary copying and/or deletion is completed. I further agree that any property situated on Company’s premises and owned by Company, including disks and other storage media, filing cabinets or other work areas, is subject to inspection by Company’s personnel at any time during my employment, with or without notice. Prior to leaving, I hereby agree to: provide Company any and all information needed to access any Company property or information returned or required to be returned pursuant to this paragraph, including without limitation any login, password, and account information; cooperate with Company in attending an exit interview; and complete and sign Company’s termination statement if required to do so by Company.

9. Legal and Equitable Remedies. I agree that (a) it may be impossible to assess the damages caused by my violation of this Agreement or any of its terms, (b) any threatened or actual violation of this Agreement or any of its terms will constitute immediate and irreparable injury to Company, and (c) Company will have the right to enforce this Agreement by injunction, specific performance or other equitable relief, without bond and without prejudice to any other rights and remedies that Company may have for a breach or threatened breach of this Agreement. If Company enforces this Agreement through a court order, I agree that the restrictions of Section 5 will remain in effect for a period of 12 months from the effective date of the order enforcing the Agreement.

10. Notices. Any notices required or permitted under this Agreement will be given to Company at its headquarters location at the time notice is given, labeled “Attention Chief Executive Officer,” and to me at my address as listed on Company payroll, or at such other address as Company or I may designate by written notice to the other. Notice will be effective upon receipt or refusal of delivery. If delivered by certified or registered mail, notice will be considered to have been given five business days after it was mailed, as evidenced by the postmark. If delivered by courier or express mail service, notice will be considered to have been given on the delivery date reflected by the courier or express mail service receipt.

11. Publication of This Agreement to Subsequent Employer or Business Associates of Employee. If I am offered employment, or the opportunity to enter into any business venture as owner, partner, consultant or other capacity, while the restrictions in Section 5 of this Agreement are in effect, I agree to inform my potential employer, partner, co-owner and/or others involved in managing the business I have an opportunity to be associated with, of my obligations under this Agreement and to provide such person or persons with a copy of this Agreement. I agree to inform Company of all employment and business ventures which I enter into while the restrictions described in Section 5 of this Agreement are in effect and I authorize Company to provide copies of this Agreement to my employer, partner, co-owner and/or others involved in managing the business I have an opportunity to be associated with and to make such persons aware of my obligations under this Agreement.

12. General Provisions.

12.1 Governing Law; Consent to Personal Jurisdiction. This Agreement will be governed by and construed according to the laws of the State of California without regard to any conflict of laws principles that would require the application of the laws of a different jurisdiction. I expressly consent to the personal jurisdiction and venue of the state and federal courts located in California for any lawsuit filed there against me by Company arising from or related to this Agreement.

12.2 Severability. If any portion of this Agreement is, for any reason, held to be invalid, illegal or unenforceable, such invalidity, illegality or unenforceability will not affect the other provisions of this Agreement, and this Agreement will be construed as if such provision had never been contained in this Agreement. If any portion of this Agreement is, for any reason, held to be excessively broad as to duration, geographical scope, activity or subject, it will be construed by limiting and reducing it, so as to be enforceable to the extent allowed by the then applicable law.

12.3 Successors and Assigns. This Agreement is for my benefit and the benefit of Company and its and their successors, assigns, parent corporations, subsidiaries, affiliates, and purchasers, and will be binding upon my heirs, executors, administrators and other legal representatives.

12.4 Survival. This Agreement will survive the termination of my employment, regardless of the reason, and the assignment of this Agreement by Company to any successor in interest or other assignee.

Employee Confidential Information and Inventions Assignment Agreement

Page 5

12.5 Employment At-Will. I understand and agree that nothing in this Agreement will change my at-will employment status or confer any right with respect to continuation of employment by Company, nor will it interfere in any way with my right or Company’s right to terminate my employment at any time, with or without cause or advance notice.

12.6 Waiver. No waiver by Company of any breach of this Agreement will be a waiver of any preceding or succeeding breach. No waiver by Company of any right under this Agreement will be construed as a waiver of any other right. Company will not be required to give notice to enforce strict adherence to all terms of this Agreement.

12.7 Export. I agree not to export, reexport, or transfer, directly or indirectly, any U.S. technical data acquired from Company or any products utilizing such data, in violation of the United States export laws or regulations.

12.8 Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument. Counterparts may be delivered via facsimile, electronic mail (including pdf or any electronic signature complying with the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act or other applicable law) or other transmission method and any counterpart so delivered will be deemed to have been duly and validly delivered and be valid and effective for all purposes.

12.9 Advice of Counsel. I ACKNOWLEDGE THAT, IN EXECUTING THIS AGREEMENT, I HAVE HAD THE OPPORTUNITY TO SEEK THE ADVICE OF INDEPENDENT LEGAL COUNSEL, AND I HAVE READ AND UNDERSTOOD ALL OF THE TERMS AND PROVISIONS OF THIS AGREEMENT. THIS AGREEMENT WILL NOT BE CONSTRUED AGAINST ANY PARTY BY REASON OF THE DRAFTING OR PREPARATION OF THIS AGREEMENT.

12.10 Entire Agreement. The obligations in Sections 1 and 2 (except Section 2.2 and Section 2.7, in each case, with respect to a consulting relationship) of this Agreement will apply to any time during which I was previously engaged, or am in the future engaged, by Company as a consultant, employee or other service provider if no other agreement governs nondisclosure and assignment of inventions during such period. This Agreement is the final, complete and exclusive agreement of the parties with respect to the subject matter of this Agreement and supersedes and merges all prior discussions between us, provided, however, if, prior to execution of this Agreement, Company and I were parties to any agreement regarding the subject matter hereof, that agreement will be superseded by this Agreement prospectively only. No modification of or amendment to this Agreement will be effective unless in writing and signed by the party to be charged. Any subsequent change or changes in my duties, salary or compensation will not affect the validity or scope of this Agreement.
