5

ACTIVE/106737552.1

determinations shall be conclusive and binding upon Employee and the Company for all purposes.  The Company shall cause the Accountants to provide its determinations and any supporting calculations with respect to Employee to the Company and Employee.  For purposes of making the calculations required by this Section, the Accountants 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.  The Company and Employee shall furnish to the Accountants such information and documents as the Accountants may reasonably request in order to make a determination under this Section.  The Company shall bear all costs the Accountants may reasonably incur in connection with any calculations contemplated by this Section.

10.Miscellaneous.  

10.1Arbitration.  Employee and the Company agree to submit to mandatory binding arbitration, in Boston, Massachusetts, any and all claims arising out of or related to this Agreement and Employee’s employment with the Company and the termination thereof, except that each party may, at its or his option, seek injunctive relief in court related to the improper use, disclosure or misappropriation of a party’s proprietary, confidential or trade secret information.  EMPLOYEE AND THE COMPANY HEREBY WAIVE ANY RIGHTS TO TRIAL BY JURY IN REGARD TO SUCH CLAIMS.  This Agreement to arbitrate does not restrict Employee’s right to file administrative claims Employee may bring before any government agency where, as a matter of law, the parties may not restrict Employee’s ability to file such claims (including, but not limited to, the National Labor Relations Board, the Equal Employment Opportunity Commission and the Department of Labor).  However, Employee and the Company agree that, to the fullest extent permitted by law, arbitration shall be the exclusive remedy for the subject matter of such administrative claims.  The arbitration shall be conducted through JAMS before a single neutral arbitrator, in accordance with the JAMS employment arbitration rules then in effect.  The arbitrator shall issue a written decision that contains the essential findings and conclusions on which the decision is based.  

10.2Indemnification.  The Company shall indemnify Employee with respect to activities in connection with his employment hereunder to the fullest extent provided in the Company’s bylaws.  Employee will be named as an insured on the director and officer liability insurance policy currently maintained, or as may be maintained by the Company from time to time, and, in addition, Employee will enter into the form of indemnification agreement provided to other similarly situated executive officers and directors of the Company.

10.3Section 409A.  To the extent (i) any payments or benefits to which Employee becomes entitled under this Agreement, or under any agreement or plan referenced herein, in connection with Employee’s termination of employment with the Company constitute deferred compensation subject to Section 409A of the Code and (ii) Employee is deemed at the time of such termination of employment to be a “specified employee” under Section 409A of the Code, then such payments shall not be made or commence until the earliest of (a) the expiration of the six (6)-month period measured from the date of Employee’s “separation from service” (as such term is at the time defined in Treasury Regulations under Section 409A of the Code) from the Company; or (b) the date of Employee’s death following such separation from service; provided, however, that such deferral shall only be effected to the extent required to avoid adverse tax

6

ACTIVE/106737552.1

treatment to Employee, including (without limitation) the additional twenty percent (20%) tax for which Employee would otherwise be liable under Section 409A(a)(1)(B) of the Code in the absence of such deferral.  Upon the expiration of the applicable deferral period, any payments which would have otherwise been made during that period (whether in a single sum or in installments) in the absence of this paragraph shall be paid to Employee or Employee’s beneficiary in one lump sum (without interest).  Any termination of Employee’s employment is intended to constitute a “separation from service” and will be determined consistent with the rules relating to a “separation from service” as such term is defined in Treasury Regulation Section 1.409A-1.  It is intended that each installment of the payments provided hereunder constitute separate “payments” for purposes of Treasury Regulation Section 1.409A-2(b)(2)(i).  It is further intended that payments hereunder satisfy, to the greatest extent possible, the exemption from the application of Section 409A of the Code (and any state law of similar effect) provided under Treasury Regulation Section 1.409A-1(b)(4) (as a “short-term deferral”).  To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision will be read in such a manner so that all payments hereunder comply with Section 409A of the Code.  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 Section 409A of the Code, 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 lifetime 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 Employee incurred such expenses, 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.  

10.4Severability.  If any provision of this Agreement shall be found by any arbitrator or court of competent jurisdiction to be invalid or unenforceable, then the parties hereby waive such provision to the extent of its invalidity or unenforceability and agree that all other provisions in this Agreement shall continue in full force and effect.

10.5No Waiver.  The failure by either party at any time to require performance or compliance by the other of any of its obligations or agreements shall in no way affect the right to require such performance or compliance at any time thereafter.  The waiver by either party of a breach of any provision hereof shall not be taken or held to be a waiver of any preceding or succeeding breach of such provision or as a waiver of the provision itself.  No waiver of any kind shall be effective or binding, unless it is in writing and is signed by the party against whom such waiver is sought to be enforced.

10.6Assignment.  This Agreement and all rights hereunder are personal to Employee and may not be transferred or assigned by Employee at any time.  The Company may assign its rights, together with its obligations hereunder, to any purchaser of all or substantially all of its business and assets, provided, however, that any such assignee assumes the Company’s obligations hereunder.

10.7Withholding.  All sums payable to Employee hereunder shall be in United States Dollars and shall be reduced by all federal, state, local and other withholding and similar taxes and payments required by applicable law.

ACTIVE/106737552.1

10.8Continuing Obligations.  For purposes of this Agreement, the obligations that arise in the Restrictive Covenants Agreement, the Prior Exhibits, the Equity Documents, and any other agreement relating to confidentiality, assignment of inventions, or other restrictive covenants shall collectively be referred to as the “Continuing Obligations.”  

10.9Amendment.  The parties understand and agree that this Agreement may not be amended, modified or waived, in whole or in part, except in a writing executed by Employee and the Company.

10.10Notices.  All notices, if any, and all other communications, if any, required or permitted under this Agreement shall be in writing and hand delivered, sent via facsimile, sent by registered first class mail, postage pre-paid, or sent by nationally recognized express courier service.  Such notices and other communications shall be effective upon receipt if hand delivered or sent via facsimile, five (5) days after mailing if sent by mail, and one (l) day after dispatch if sent by express courier, to the following addresses, or such other addresses as any party shall notify the other parties:

10.11Binding Nature.  This Agreement shall be binding upon, and inure to the benefit of, the successors and personal representatives of the respective parties hereto.

10.12Counterparts.  This Agreement may be executed in two or more counterparts, each of which shall be deemed to be an original but all of which, taken together, constitute one and the same agreement.

10.13Governing Law.  This Agreement and the rights and obligations of the parties hereto shall be construed in accordance with the laws of the State of Delaware, without giving effect to the principles of conflict of laws.

10.14Attorneys’ Fees.  In the event of any claim, demand or suit arising out of or with respect to this Agreement, the prevailing party shall be entitled to reasonable costs and attorneys’ fees, including any such costs and fees upon appeal.  

10.15Entire Agreement.  This Agreement (and the exhibit(s) hereto, including but not limited to the Restrictive Covenants Agreement) together with the Equity Documents, as amended, and the Prior Exhibits (and any exhibits and/or attachments thereto) constitute the entire and only agreement and understanding between the parties relating to Employee’s employment with Company.   Subject to the foregoing, this Agreement supersedes and cancels any and all previous contracts, arrangements or understandings with respect to Employee’s employment.

ACTIVE/106737552.1

EMPLOYEE RESTRICTIVE COVENANTS AGREEMENT

In exchange for consideration which Employee (as defined below) acknowledges and agrees is fair and reasonable, Ercem Atillasoy (“Employee”) and Allovir, Inc., on behald of itself and its subsidiaries, affiliates, successors or assigns (together the “Company”), enter into this Restrictive Covenants Agreement (this “Agreement”), and hereby agree to the following:

(a)Company Information.  Employee agrees at all times during the term of Employee’s employment and thereafter, to hold in strictest confidence, and not to use, except for the benefit of the Company, or to disclose to any person, firm or corporation without written authorization of the Board of Directors of the Company, any Proprietary Information of the Company, except under a non-disclosure agreement duly authorized and executed by the Company.  Employee understands that “Proprietary Information” means any non-public information regarding or relating to the Company or its products including:  (1) the actual or anticipated business or research and development of the Company, technical data, trade secrets or know-how, including, but not limited to, research, product plans or other information regarding the Company's products or services and markets therefore; (2) research, clinical or other trials, developments, inventions, processes, formulas, technology, designs, drawings, engineering, software, hardware configuration information, marketing, finances or other business information; (3) customer lists and customers (including, but not limited to, customers of the Company on whom Employee called or with whom Employee became acquainted during the term of Employee’s employment); (4) the identity, skills and compensation of employees, consultants, or contractors; (5) policies and procedures of the Company; (6) anything related to Company Inventions (as defined herein); and (7) Third Party Information (as defined herein).  Employee further understands that Proprietary Information does not include any of the foregoing items which have become publicly known and made generally available through no wrongful act of the Employee or of others who were under confidentiality obligations as to the item or items involved or improvements or new versions thereof. Notwithstanding the foregoing, pursuant to 18 U.S.C. Section 1833(b), Employee shall 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. In addition, notwithstanding the foregoing, Employee shall not be prohibited from disclosing Proprietary Information to a government agency as a whistleblower.

(b)Third Party Information. Employee recognizes that the Company has received and in the future will receive from third parties their confidential or proprietary information subject to a duty on the Company's part to maintain the confidentiality of such information and to use it only for certain limited purposes ("Third Party Information").  Employee agrees to hold all Third Party Information in the strictest confidence and not to disclose it to any person, firm or corporation or to use it except as necessary in carrying out Employee’s work for the Company consistent with the Company's agreement with such third party.

ACTIVE/106737552.1

(a)Inventions Retained and Licensed.  Employee has attached hereto, as Exhibit 1, a list describing all inventions, original works of authorship, developments, improvements, and trade secrets which were made by Employee prior to Employee’s employment with the Company (collectively referred to as “Prior Inventions”), which belong to Employee, which relate to the Company's proposed business, products or research and development, and which are not assigned to the Company hereunder; or, if no such list is attached, Employee represents that there are no such Prior Inventions.  If in the course of Employee’s employment with the Company, Employee incorporates into a Company product, process or service a Prior Invention owned by Employee or in which Employee has an interest, Employee hereby grants to the Company a nonexclusive, royalty-free, fully paid-up, irrevocable, perpetual, worldwide license to make, have made, modify, use and sell such Prior Invention as part of or in connection with such product, process or service, and to practice any method related thereto.

(b)Assignment of Inventions.  Employee agrees that Employee will promptly make full written disclosure to the Company, will hold in trust for the sole right and benefit of the Company, and hereby assign (or, for future inventions, agree to assign) to the Company, or its designee, all Employee’s right, title, and interest in and to any and all inventions, original works of authorship, writings, developments, concepts, improvements, designs, discoveries, ideas, processes, formulas, data, trademarks or trade secrets, whether or not patentable or registrable under copyright or similar laws, which Employee may solely or jointly conceive or develop or reduce to practice within the scope of Employee’s  employment, or cause to be conceived or developed or reduced to practice, during the period of time Employee is employed by the Company (collectively referred to as “Inventions”), except as provided in Section 2(f) below.   Employee agrees that Company will exclusively own all work product that is made by Employee (solely or jointly with others) within the scope of Employee’s employment.   Employee further acknowledges that all original works of authorship which are made by Employee (solely or jointly with others) within the scope of and during the period of Employee’s employment with the Company and which are protectable by copyright are "works made for hire," as that term is defined in the United States Copyright Act.  Employee understands and agrees that the decision whether or not to commercialize or market any Invention developed by Employee solely or jointly with others is within the Company's sole discretion and for the Company's sole benefit and that no royalty will be due to Employee as a result of the Company's efforts to commercialize or market any such Invention.  Employee acknowledges and agrees that nothing in this Agreement shall be deemed to grant, by implication, estoppel or otherwise, a license from the Company to me to make, use, license, or transfer in any way an existing or future Invention.

(c)Inventions Assigned to the United States.  Employee agrees to assign to the United States government all Employee’s right, title, and interest in and to any and all Inventions whenever such full title is required to be in the United States by a contract between the Company and the United States or any of its agencies.

ACTIVE/106737552.1

(d)Maintenance of Records. Employee agrees to keep and maintain adequate and current written records of all Inventions made by Employee (solely or jointly with others) during the term of Employee’s employment with the Company.  The records will be in the form of notes, sketches, drawings, and any other format that may be specified by the Company.  The records will be available to and remain the sole property of the Company at all times.

(e)Patent and Copyright Registrations.  Employee agrees to assist the Company, or its designee, at the Company's expense, in every proper way to secure the Company's rights in the Inventions and any copyrights, patents, mask work rights or other intellectual property rights relating thereto in any and all countries, including the disclosure to the Company of all pertinent information and data with respect thereto, the execution of all applications, specifications, oaths, assignments and all other instruments which the Company shall deem necessary in order to apply for and obtain such rights and in order to assign and convey to the Company, its successors, assigns, and nominees the sole and exclusive rights, title and interest in and to such Inventions, and any copyrights, patents, mask work rights or other intellectual property rights relating thereto.  Employee further agrees that Employee’s obligation to execute or cause to be executed, when it is in Employee’s power to do so, any such instrument or papers shall continue after the termination of this Agreement.  If the Company is unable because of Employee’s mental or physical incapacity or for any other reason to secure Employee’s signature to apply for or to pursue any application for any United States or foreign patents or copyright registrations covering Inventions or original works of authorship assigned to the Company as above, then Employee hereby irrevocably designates and appoints the Company and its duly authorized officers and agents as Employee’s agent and attorney in fact, to act for and in Employee’s behalf and stead to execute and file any such applications and to do all other lawfully permitted acts to further the prosecution and issuance of letters patent or copyright registrations thereon with the same legal force and effect as if executed by Employee.

(f)Exceptions.  This Agreement does not obligate Employee to assign to the Company any Invention that, in the sole judgment of the Company, reasonably exercised, is developed entirely on my own time and does not relate to the business efforts or research and development efforts in which, during the period of my employment, the Company actually is engaged or reasonably would be engaged, and does not result from the use of premises or equipment owned or leased by the Company.  However, Employee will also promptly disclose to the Company any such Inventions for the purpose of determining whether they qualify for such exclusion.  Employee understands that to the extent this Agreement is required to be construed in accordance with the laws of any state which precludes a requirement in an employee agreement to assign certain classes of inventions made by an employee, this Section 2 will be interpreted not to apply to any invention that a court rules and/or the Company agrees falls within such classes.

(a)In order to protect the Company’s Proprietary Information and goodwill, during Employee’s employment and for a period of (i) one (1) year following the date of the cessation of Employee’s employment with the Company (the “Last Date of Employment”) or such shorter period as the Company designates in writing to Employee (which designation must be made no later than the date any waiver must be made under Section 5(b)(iii)), or (ii) two (2) years following the Last Date of Employment if Employee breaches his fiduciary duty to the Company or if Employee has unlawfully taken, physically or electronically, property belonging to the Company (in either case, the “Restricted Period”), Employee shall not directly or indirectly, whether as owner, partner, shareholder, director, manager, consultant, agent, employee, co-venturer or otherwise, anywhere in the world, engage or otherwise participate in any business that develops, manufactures or markets any products, performs any services, or conducts any research focused on using T-cell therapy to address viruses or virus-related diseases (the “Noncompetition Restriction”).

(b)Notwithstanding the foregoing, the Noncompetition Restrictions shall not apply: (i) if the Company terminates Employee’s employment without “cause” (within the meaning of Mass. Gen. Laws Chapter 149, Sec 24L (c)); (ii) if the Employee has been laid off by the Company; (iii) if the Company waives the Noncompetition Restriction; or (iv) to Employee’s activities on behalf of ElevateBio Management, Inc., or its subsidiaries and affiliates.  

(c)In the event that the Non-Competition Restriction applies to Employee, the Company shall make garden leave payments to Employee for the post-employment portion of the Restricted Period (but for not more than 12 months following the end of Employee’s employment) at the rate of 50% of the highest annualized base salary paid to Employee by the Company within the two-year period preceding the last day of Employee’s employment (the “Garden Leave Pay”).  Employee acknowledges and agrees that the Garden Leave Pay is consideration mutually agreed upon by the Company and Employee, and in exchange for Employee’s agreement to the Noncompetition Restriction.  Employee further acknowledges and agrees that any Garden Leave Pay he receives pursuant to this Agreement shall reduce (and shall not be in addition to) any severance or separation pay that Employee is otherwise entitled to receive from the Company pursuant to any agreement, plan or otherwise.
