Exhibit 10.4
2SEVENTY BIO, INC.
NON-EMPLOYEE DIRECTOR COMPENSATION POLICY
The purpose of this Non-Employee Director Compensation Policy (the “Policy”) of 2seventy bio, Inc. (the “Company”) is to provide a total compensation package that enables the Company to attract and retain, on a long-term basis, high-caliber directors who are not employees or officers of the Company or its subsidiaries (“Outside Directors”).  This Policy will become effective as of the completion of the distribution of all of the outstanding shares of the Company by bluebird bio, Inc. to bluebird bio, Inc.’s stockholders (the “Effective Date”).  In furtherance of the purpose stated above, all Outside Directors shall be paid compensation for services provided to the Company as set forth below:
Cash Retainers
Annual Retainer for Board Membership:   $45,000 for general availability and participation in meetings and conference calls of our Board of Directors, to be paid quarterly in arrears, pro-rated based on the number of actual days served by the director during such calendar quarter.  No additional compensation will be paid for attending individual meetings of the Board of Directors.
Additional Annual Retainer for Non-Executive Chair:                $35,000
Additional Annual Retainers for Committee Membership:
Audit Committee Chair:    $18,000
Audit Committee member:      $9,000
Compensation Committee Chair:    $15,000
Compensation Committee member:      $7,500

Chair and committee member retainers are in addition to retainers for members of the Board of Directors.  No additional compensation will be paid for attending individual committee meetings of the Board of Directors.
Equity Retainers
Initial Award: An initial, one-time equity award (the “Initial Award”) will be granted to each new Outside Director upon his or her election to the Board of Directors. The Compensation Committee will review this Policy on an annual basis and determine the Value and form of the Initial Award.  The Initial Award shall vest in equal annual installments over three years from the date of grant; provided, however, that all vesting shall cease if the director ceases to have a Service Relationship (as defined in the Company’s 2021 Stock Option and Incentive Plan). Any stock option portion of the Initial Award shall expire ten years from the date of grant, and shall have a per share exercise price equal to the Fair Market Value (as defined in the Company’s 2021 Stock Option and Incentive Plan) of the Company’s common stock on the date of grant.  This Initial Award applies only to Outside Directors who are first elected to the Board of Directors subsequent to the Effective Date.

Annual Award:  On each date of each Annual Meeting of Stockholders of the Company following the Effective Date (the “Annual Meeting”), each continuing Outside Director, other than a director receiving an Initial Award, will receive an annual equity award (the “Annual Award”). The Compensation Committee will review this Policy on an annual basis and determine the Value and form of the Annual Award.  The Annual Award shall vest in full upon the earlier of (i) the first anniversary of the date of grant or (ii) the date of the next Annual Meeting; provided, however, that all vesting shall cease if the director ceases to have a Service Relationship, unless the Board of Directors determines that the circumstances warrant continuation of vesting.  Any stock option portion of such Annual Award shall expire ten years from the date of grant, and shall have a per share exercise price equal to the Fair Market Value of the Company’s common stock on the date of grant.
Value:  For purposes of this Policy, “Value” means with respect to (i) any stock option award, the grant date fair value of the option (i.e., Black-Scholes Value) determined in accordance with the reasonable assumptions and methodologies employed by the Company for calculating the fair value of options under Financial Accounting Standard Board (“FASB”) Accounting Standards Codification (“ASC”) Topic 718; and (ii) any award of restricted stock or restricted stock units the product of (A) the closing market price on the Nasdaq Global Market (or such other market on which the Company’s common stock is then principally listed) of one share of the Company’s common stock on the grant date, and (B) the aggregate number of shares of common stock underlying such award.
Sale Event Acceleration: All outstanding Initial Awards and Annual Awards held by an Outside Director shall become fully vested and exercisable or nonforfeitable upon a Sale Event (as defined in the Company’s 2021 Stock Option and Incentive Plan).
Expenses
The Company will reimburse all reasonable out-of-pocket expenses incurred by non-employee directors in attending meetings of the Board of Directors or any committee thereof.
Compensation Limits
The aggregate amount of compensation, including both equity compensation and cash compensation, paid by the Company to any Outside Director in a calendar year for services as an Outside Director period shall not exceed the 75th percentile of the mean of the total amount of cash and equity compensation paid to non-employee directors of the Company’s then-applicable peer group as approved by the Compensation Committee of the Board of Directors; provided, however, that, for the Chair of the Board, such amount shall not exceed 1.25 times the average total compensation paid to incumbent Outside Directors for such year. For the purpose of these limitations, the value of any equity award shall be its grant date fair value, as determined in accordance with FASB ASC 718 or successor provision but excluding the impact of estimated forfeitures related to service-based vesting provisions.

–Nicola shall have the rights to terminate employment according to the terms of the executive agreement;
–Nicola shall have the rights to severance payments as set forth in the executive agreement;

The form of executive agreement is set forth in Appendix A attached hereto.  The Parties anticipate that they will enter into a more detailed side letter upon execution of the agreement with Globalization Partners, including execution of the Employee Confidentiality, Assignment, Nonsolicitation and Noncompetition Agreement.

Exhibit A

FORM OF
EMPLOYMENT AGREEMENT

This Employment Agreement (“Agreement”) is made between 2seventy bio, Inc. (the “Company”), and [______] (the “Executive”). Except for the Preserved Obligations (as defined below), this Agreement supersedes in all respects all prior and contemporaneous agreements, representations and communications between the Executive and the Company, and between the Executive and bluebird bio, Inc. (“bluebird”), regarding the employment of the Executive with either the Company or bluebird, including without limitation the Employment Agreement between the Executive and bluebird dated [___________] (including any amendments, the “Prior Employment Agreement”).  In entering into this Agreement, in consideration for the opportunity to receive the compensation and benefits provided herein, the Executive hereby waives any right or potential right the Executive may have to receive: (i) any severance or change in control compensation or benefits under the Prior Employment Agreement, under any bluebird severance plan or under any other agreement or arrangement with bluebird, and (ii) any compensation or benefits related to the Executive’s employment termination or other service relationship termination from bluebird, whether under the Prior Employment Agreement or otherwise.
WHEREAS, the Company desires to employ the Executive and the Executive desires to be employed by the Company beginning on the closing of the transactions contemplated by [DESCRIBE TRANSACTION] (the “Transaction”) (such closing date, the “Effective Date”) on the terms and conditions contained herein.  If the Transaction does not close, this Agreement shall be void. 
NOW, THEREFORE, in consideration of the mutual covenants and agreements herein contained and other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties agree as follows:
1.Employment.
(a)Term.  The Company shall employ the Executive and the Executive shall be employed by the Company pursuant to this Agreement commencing as of the Effective Date and continuing until such employment is terminated in accordance with the provisions hereof (the “Term”).  The Executive’s employment with the Company shall be “at will,” meaning that the Executive’s employment may be terminated by the Company or the Executive at any time and for any reason subject to the terms of this Agreement.
(b)Position and Duties.  The Executive shall serve as the [Chief Executive Officer (“CEO”)/ Chief Security Officer (“CSO”)/ Chief Operating Officer (“COO”) / Chief Financial Officer (“CFO”)] of the Company and shall have such powers and duties as may from time to time be prescribed by the Company’s Chief Executive Officer and the Board of Directors (including any committee thereof, the “Board”).  The Executive shall devote the Executive’s full working time and efforts to the business and affairs of the Company. Notwithstanding the foregoing sentence, the Executive may serve on other boards of directors, with the approval of the Board, or engage in religious, charitable or other community activities as long as such services and activities do not interfere with the Executive’s performance of the Executive’s duties to the Company.

2.Compensation and Related Matters.
(a)Base Salary.  The Executive’s initial base salary shall be paid at the rate of  $[__________] per year.  The Executive’s base salary shall be subject to periodic review and adjustment by the Board.  The base salary in effect at any given time is referred to herein as “Base Salary.”  The Base Salary shall be payable in a manner that is consistent with the Company’s usual payroll practices for its executive officers.
(b)Annual Bonus.  During the Term, the Executive shall be eligible to receive an annual cash bonus.  The Executive’s target annual bonus shall be [__]% of Executive’s Base Salary.  The criteria for any bonus, whether any bonus is earned and the amount of any bonus each shall be determined by the Board in its sole discretion.  To earn any bonus, the Executive must be employed by the Company on the day the Company pays the bonus.  Any bonus for the calendar year in which the Effective Date occurs shall be prorated based on when in the year the Effective Date occurs.
(c)Equity.  The Executive may be eligible for stock option grants as determined by the Board in its discretion. 
(d)Vacation.  The Executive shall be eligible for vacation, subject in all respects to the Company’s vacation policy in effect from time to time, which is subject to change by the Company.
(e)Other Benefits.  The Executive shall be eligible to participate in or receive benefits under the Company’s employee benefit plans in effect from time to time, subject to the terms of such plans.  Company benefit plans are subject to change in the Company’s discretion.
3.Termination.  The Executive’s employment hereunder may be terminated without any breach of this Agreement under the following circumstances:
(a)Death.  The Executive’s employment hereunder shall terminate upon death.
(b)Disability.  The Company may terminate the Executive’s employment if the Executive is disabled and unable to perform or expected to be unable to perform the essential functions of the Executive’s then existing position or positions under this Agreement with or without reasonable accommodation for a period of 90 days (which need not be consecutive) in any 12-month period.  If any question shall arise as to whether during any period the Executive is disabled so as to be unable to perform the essential functions of the Executive’s then existing position or positions with or without reasonable accommodation, the Executive may, and at the request of the Company shall, submit to the Company a certification in reasonable detail by a physician selected by the Company as to whether the Executive is so disabled or how long such disability is expected to continue, and such certification shall for the purposes of this Agreement be conclusive of the issue.  The Executive shall cooperate with any reasonable request of the physician in connection with such certification.  If such question shall arise and the Executive shall fail to submit such certification, the Company’s determination of such issue shall be binding on the Executive.  
(c)Termination by the Company for Cause.  The Company may terminate the Executive’s employment hereunder for Cause.  For purposes of this Agreement, “Cause” shall mean any of the following: (i) the Executive’s commission of any felony or commission of any crime involving fraud, dishonesty or moral turpitude; (ii) the Executive’s commission or attempted commission of or participation in a fraud or act of dishonesty against the Company; (iii) the Executive’s material breach of any contract or agreement between the Executive and the 

Company or bluebird or the Executive’s material breach of any legal duty the Executive owes to the Company; (iv) conduct by the Executive that constitutes insubordination, incompetence or neglect of duties; or (v) the Executive’s failure to perform the duties, functions and responsibilities of the Executive’s position; provided, however, the actions or conduct described in clauses (iv) and (v) above shall only constitute Cause if the Company provides the Executive with written notice thereof and the Executive has not cured within 30 days of such written notice.
(d)Termination by the Company without Cause.  The Company may terminate the Executive’s employment hereunder at any time without Cause.  To avoid doubt, a termination due to Disability or the death of the Executive shall not constitute a termination without Cause. 
(e)Termination by the Executive.  The Executive may terminate the Executive’s employment hereunder at any time for any reason, including but not limited to Good Reason.  
(i)For purposes of this Agreement, “Good Reason” shall mean that the Executive has complied with the “Good Reason Process” (hereinafter defined) following the occurrence of any of the following events without the Executive’s express written consent:  (i) a material diminution in the Executive’s responsibilities, authority and function that occurs after a subsequent Change in Control (as defined below) (to avoid doubt, this Transaction does not constitute such Change in Control); (ii) a material reduction in the Executive’s Base Salary except pursuant to a salary reduction affecting substantially all of the senior executives of the Company, provided, that it does not adversely affect the Executive to a disproportionately greater extent than other such senior executives; (iii) a material change of at least 40 miles in the geographic location of the principal physical office of the Company to which the Executive is required to report by the Company (not including any remote working arrangement, or the cessation of any remote working arrangement, related to the COVID-19 pandemic, and not including travel on Company business); or (iv) the material breach by the Company of this Agreement. 
(ii)“Good Reason Process” shall mean that (i) the Executive reasonably determines in good faith that a “Good Reason” condition has occurred; (ii) the Executive notifies the Company in writing of the first occurrence of the Good Reason condition within 60 days of the first occurrence of such condition; (iii) the Executive cooperates in good faith with the Company’s efforts, for a period not less than 30 days following such notice (the “Cure Period”) to remedy the condition; (iv) notwithstanding such efforts, the Good Reason condition continues to exist; and (v) the Executive terminates his employment within 60 days after the end of the Cure Period.  If the Company cures the Good Reason condition during the Cure Period, Good Reason shall be deemed not to have occurred.
4.Matters Related to Termination.
(a)Notice of Termination.  Except for termination as specified in Section 3(a), any termination of the Executive’s employment by the Company or any such termination by the Executive shall be communicated by written Notice of Termination to the other party hereto.  For purposes of this Agreement, a “Notice of Termination” shall mean a notice which shall indicate the specific termination provision in this Agreement relied upon.
(b)Date of Termination.  “Date of Termination” shall mean:  (i) if the Executive’s employment is terminated by death, the date of death; (ii) if the Executive’s employment is terminated on account of disability under Section 3(b) or by the Company for 

Cause under Section 3(c), the date on which Notice of Termination is given; (iii) if the Executive’s employment is terminated by the Company without Cause under Section 3(d), the date on which a Notice of Termination is given or the date otherwise specified by the Company in the Notice of Termination; (iv) if the Executive’s employment is terminated by the Executive under Section 3(e) other than for Good Reason, 14 days after the date on which a Notice of Termination is given, and (v) if the Executive’s employment is terminated by the Executive under Section 3(e) for Good Reason, the date on which a Notice of Termination is given after the end of the Cure Period.  Notwithstanding the foregoing, in the event that the Executive gives a Notice of Termination to the Company, the Company may unilaterally accelerate the Date of Termination and such acceleration shall not result in a termination by the Company for purposes of this Agreement.
(c)Accrued Obligations.  If the Executive’s employment with the Company is terminated for any reason, the Company shall pay or provide to the Executive (or to the Executive’s authorized representative or estate) (i) any Base Salary earned through the Date of Termination and, if applicable, any accrued but unused vacation through the Date of Termination; (ii) unpaid expense reimbursements (subject to, and in accordance with this Agreement); and (iii) any vested benefits the Executive may have under any employee benefit plan of the Company through the Date of Termination, which vested benefits shall be paid and/or provided in accordance with the terms of such employee benefit plans (collectively, the “Accrued Obligations”).
(d)Resignation of All Other Positions.  To the extent applicable, the Executive shall be deemed to have resigned from all applicable officer, board member and other positions that the Executive holds with the Company or any of its respective subsidiaries and affiliates upon the termination of the Executive’s employment for any reason.  The Executive shall execute any documents in reasonable form as may be requested to confirm or effectuate any such resignations.
5.Severance Pay and Benefits Upon Termination by the Company without Cause or by the Executive for Good Reason Outside the Change in Control Period.  If the Executive’s employment is terminated by the Company without Cause, or the Executive terminates employment for Good Reason, in either case outside of the Change in Control Period (as defined below), then, in addition to the Accrued Obligations, and subject to (i) the Executive signing a separation agreement and release in the form provided by the Company, which shall include, without limitation, a general release of claims against the Company and all related persons and entities that shall not release the Executive’s rights under this Agreement, a reaffirmation of all of the Executive’s Continuing Obligations (as defined below), and, in the Company’s sole discretion, a one-year post-employment noncompetition agreement, and shall provide that if the Executive breaches any of the Continuing Obligations, all payments of the Severance Amount shall immediately cease (the “Separation Agreement”), and (ii) the Separation Agreement becoming irrevocable, all within 60 days after the Date of Termination (or such shorter period as set forth in the Separation Agreement), which shall include a seven (7) business day revocation period:
(a)the Company shall pay the Executive an amount equal to 12 months of the Executive’s Base Salary (the “Severance Amount”); provided that in the event the Executive is entitled to any payments pursuant to the Restrictive Covenants Agreement, the Severance Amount received in any calendar year will be reduced by the amount the Executive is paid in the same such calendar year pursuant to the Restrictive Covenants Agreement (the “Restrictive Covenants Agreement Setoff”); and
(b)subject to the Executive’s copayment of premium amounts at the applicable active employees’ rate and the Executive’s proper election to receive benefits under 

the Consolidated Omnibus Budget Reconciliation Act of 1985, as amended (“COBRA”), the Company shall pay to the group health plan provider or the COBRA provider a monthly payment equal to the monthly employer contribution that the Company would have made to provide health insurance to the Executive if the Executive had remained employed by the Company until the earliest of (A) the end of the period over which the Severance Amount is paid; (B) the date that the Executive becomes eligible for group medical plan benefits under any other employer’s group medical plan; or (C) the cessation of the Executive’s health continuation rights under COBRA; provided, however, that if the Company determines that it cannot pay such amounts to the group health plan provider or the COBRA provider (if applicable) without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then the Company shall convert such payments to payroll payments directly to the Executive for the time period specified above.  Such payments to the Executive shall be subject to tax-related deductions and withholdings and paid on the Company’s regular payroll dates.
The amounts payable under Section 5, to the extent taxable, shall be paid out in substantially equal installments in accordance with the Company’s payroll practice over 12 months commencing within 60 days after the Date of Termination; provided, however, that if the 60-day period begins in one calendar year and ends in a second calendar year, such payments, to the extent they qualify as “non-qualified deferred compensation” within the meaning of Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”), shall begin to be paid in the second calendar year by the last day of such 60-day period; provided, further, that the initial payment shall include a catch-up payment to cover amounts retroactive to the day immediately following the Date of Termination.  Each payment pursuant to this Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2).
The receipt of any severance payments or benefits pursuant to this Section will be subject to Executive not violating the Continuing Obligations.  In the event Executive breaches the Continuing Obligations, in addition to all other legal and equitable remedies, the Company shall have the right to terminate or suspend all continuing payments and benefits to which Executive may otherwise be entitled pursuant to this Section without affecting the Executive’s release or Executive’s obligations under the Separation Agreement and Release. 
6.Severance Pay and Benefits Upon Termination by the Company without Cause or by the Executive for Good Reason within the Change in Control Period.  The provisions of this Section 6 shall apply in lieu of, and expressly supersede, the provisions of Section 5 if (i) the Executive’s employment is terminated either (a) by the Company without Cause, or (b) by the Executive for Good Reason, and (ii) the Date of Termination is on or within 12 months after the occurrence of the first event constituting a Change in Control (such period, the “Change in Control Period”). These provisions shall terminate and be of no further force or effect after the Change in Control Period.
(a)If the Executive’s employment is terminated by the Company without Cause or the Executive terminates employment for Good Reason, and in either case the Date of Termination occurs during the Change in Control Period, then, in addition to the Accrued Obligations, and subject to the signing of a general release of claims against the Company and all related persons and entities that shall not release the Executive’s rights under this Agreement (the “Release”) by the Executive and the Release becoming fully effective, all within the time frame set forth in the Release but in no event more than 60 days after the Date of Termination:
(i)the Company shall pay the Executive a lump sum in cash in an amount equal to the 1 times sum of (A) the Executive’s then-current Base Salary (or the Executive’s Base Salary in effect immediately prior to the Change in Control, if higher) plus (B) the Executive’s Target Bonus for the then-current year (or the Executive’s Target Bonus in effect immediately prior to the Change in Control, if higher) (the 

“Change in Control Payment”); provided that the Change in Control Payment shall be reduced by the amount of the Restrictive Covenants Agreement Setoff, if applicable; and
(ii)notwithstanding anything to the contrary in any applicable option agreement or other stock-based award agreement, all stock options and other stock-based awards held by the Executive that are subject solely to time-based vesting (the “Time-Based Equity Awards”) shall immediately accelerate and become fully vested and exercisable or nonforfeitable as of the later of (i) the Date of Termination or (ii) the effective date of the Release (the “Accelerated Vesting Date”), provided that in order to effectuate the accelerated vesting contemplated by this subsection, the unvested portion of the Executive’s Time-Based Equity Awards that would otherwise be forfeited on the Date of Termination will be delayed until the earlier of (A) the effective date of the Release (at which time acceleration will occur), or (B) the date that the Release can no longer become fully effective (at which time the unvested portion of the Executive’s Time-Based Equity Awards will be forfeited). Notwithstanding the foregoing, no additional time-based vesting of the Time-Based Equity Awards shall occur during the period between the Date of Termination and the Accelerated Vesting Date; and
(iii)subject to the Executive’s copayment of premium amounts at the applicable active employees’ rate and the Executive’s proper election to receive benefits under COBRA, the Company shall pay to the group health plan provider or the COBRA provider a monthly payment equal to the monthly employer contribution that the Company would have made to provide health insurance to the Executive if the Executive had remained employed by the Company until the earliest of (A) the 12 month anniversary of the Date of Termination; (B) the date that the Executive becomes eligible for group medical plan benefits under any other employer’s group medical plan; or (C) the cessation of the Executive’s health continuation rights under COBRA; provided, however, that if the Company determines that it cannot pay such amounts to the group health plan provider or the COBRA provider (if applicable) without potentially violating applicable law (including, without limitation, Section 2716 of the Public Health Service Act), then the Company shall convert such payments to payroll payments directly to the Executive for the time period specified above.  Such payments to the Executive shall be subject to tax-related deductions and withholdings and paid on the Company’s regular payroll dates.  
The amounts payable under this Section 6(a), to the extent taxable, shall be paid or commence to be paid within 60 days after the Date of Termination; provided, however, that if the 60-day period begins in one calendar year and ends in a second calendar year, such payments to the extent they qualify as “non-qualified deferred compensation” within the meaning of Section 409A of the Code, shall be paid or commence to be paid in the second calendar year by the last day of such 60-day period.
(b)Additional Limitation.
(i)Anything in this Agreement to the contrary notwithstanding, in the event that the amount of any compensation, payment or distribution by the Company to or for the benefit of the Executive, whether paid or payable or distributed or distributable pursuant to the terms of this Agreement or otherwise, calculated in a manner consistent with Section 280G of the Code, and the applicable regulations thereunder (the “Aggregate Payments”), would be subject to the excise tax imposed by Section 4999 of the Code, then the Aggregate Payments shall be reduced (but not below zero) so that the sum of all of the Aggregate Payments shall be $1.00 less than the amount at which the Executive becomes subject to the excise tax imposed by Section 4999 of the Code; provided that such reduction shall only occur if it would result in the Executive receiving 

a higher After Tax Amount (as defined below) than the Executive would receive if the Aggregate Payments were not subject to such reduction.  In such event, the Aggregate Payments shall be reduced in the following order, in each case, in reverse chronological order beginning with the Aggregate Payments that are to be paid the furthest in time from consummation of the transaction that is subject to Section 280G of the Code:  (1) cash payments not subject to Section 409A of the Code; (2) cash payments subject to Section 409A of the Code; (3) equity-based payments and acceleration; and (4) non-cash forms of benefits; provided that in the case of all the foregoing Aggregate Payments all amounts or payments that are not subject to calculation under Treas. Reg. §1.280G-1, Q&A-24(b) or (c) shall be reduced before any amounts that are subject to calculation under Treas. Reg. §1.280G-1, Q&A-24(b) or (c).
(ii)For purposes of this Section 6(b), the “After Tax Amount” means the amount of the Aggregate Payments less all federal, state, and local income, excise and employment taxes imposed on the Executive as a result of the Executive’s receipt of the Aggregate Payments.  For purposes of determining the After Tax Amount, the Executive shall be deemed to pay federal income taxes at the highest marginal rate of federal income taxation applicable to individuals for the calendar year in which the determination is to be made, and state and local income taxes at the highest marginal rates of individual taxation in each applicable state and locality, net of the maximum reduction in federal income taxes which could be obtained from deduction of such state and local taxes. 
(iii)The determination as to whether a reduction in the Aggregate Payments shall be made pursuant to Section 6(b)(i) shall be made by a nationally recognized accounting firm selected by the Company (the “Accounting Firm”), which shall provide detailed supporting calculations both to the Company and the Executive within 15 business days of the Date of Termination, if applicable, or at such earlier time as is reasonably requested by the Company or the Executive.  Any determination by the Accounting Firm shall be binding upon the Company and the Executive.
(c)Definitions.  For purposes of this Section 6, “Change in Control” shall mean any of the following:
(i)any “person,” as such term is used in Sections 13(d) and 14(d) of the Securities Exchange Act of 1934, as amended (the “Act”) (other than the Company, any of its subsidiaries, or any trustee, fiduciary or other person or entity holding securities under any employee benefit plan or trust of the Company or any of its subsidiaries), together with all “affiliates” and “associates” (as such terms are defined in Rule 12b-2 under the Act) of such person, shall become the “beneficial owner” (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, of securities of the Company representing 50 percent or more of the combined voting power of the Company’s then outstanding securities having the right to vote in an election of the Board (“Voting Securities”) (in such case other than as a result of an acquisition of securities directly from the Company); or
(ii)the date a majority of the members of the Board is replaced during any 12-month period by directors whose appointment or election is not endorsed by a majority of the members of the Board before the date of the appointment or election; or
(iii)the consummation of (A) any consolidation or merger of the Company where the stockholders of the Company, immediately prior to the consolidation or merger, would not, immediately after the consolidation or merger, beneficially own (as such term is defined in Rule 13d-3 under the Act), directly or indirectly, shares representing in the aggregate more than 50 percent of the voting shares of the Company 

issuing cash or securities in the consolidation or merger (or of its ultimate parent corporation, if any), or (B) any sale or other transfer (in one transaction or a series of transactions contemplated or arranged by any party as a single plan) of all or substantially all of the assets of the Company. 
Notwithstanding the foregoing, a “Change in Control” shall not be deemed to have occurred for purposes of the foregoing clause (i) solely as the result of an acquisition of securities by the Company which, by reducing the number of shares of Voting Securities outstanding, increases the proportionate number of Voting Securities beneficially owned by any person to 50 percent or more of the combined voting power of all of the then outstanding Voting Securities; provided, however, that if any person referred to in this sentence shall thereafter become the beneficial owner of any additional shares of Voting Securities (other than pursuant to a stock split, stock dividend, or similar transaction or as a result of an acquisition of securities directly from the Company) and immediately thereafter beneficially owns 50 percent or more of the combined voting power of all of the then outstanding Voting Securities, then a “Change in Control” shall be deemed to have occurred for purposes of the foregoing clause (i).
7.Section 409A.
(a)Anything in this Agreement to the contrary notwithstanding, if at the time of the Executive’s separation from service within the meaning of Section 409A of the Code, the Company determines that the Executive is a “specified employee” within the meaning of Section 409A(a)(2)(B)(i) of the Code, then to the extent any payment or benefit that the Executive becomes entitled to under this Agreement or otherwise on account of the Executive’s separation from service would be considered deferred compensation otherwise subject to the 20 percent additional tax imposed pursuant to Section 409A(a) of the Code as a result of the application of Section 409A(a)(2)(B)(i) of the Code, such payment shall not be payable and such benefit shall not be provided until the date that is the earlier of (A) six months and one day after the Executive’s separation from service, or (B) the Executive’s death.  If any such delayed cash payment is otherwise payable on an installment basis, the first payment shall include a catch-up payment covering amounts that would otherwise have been paid during the six-month period but for the application of this provision, and the balance of the installments shall be payable in accordance with their original schedule. 
(b)All in-kind benefits provided and expenses eligible for reimbursement under this Agreement shall be provided by the Company or incurred by the Executive during the time periods set forth in this Agreement.  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.  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 (except for any lifetime or other aggregate limitation applicable to medical expenses).  Such right to reimbursement or in-kind benefits is not subject to liquidation or exchange for another benefit.
(c)To the extent that any payment or benefit described in this Agreement constitutes “non-qualified deferred compensation” under Section 409A of the Code, and to the extent that such payment or benefit is payable upon the Executive’s termination of employment, then such payments or benefits shall be payable only upon the Executive’s “separation from service.”  The determination of whether and when a separation from service has occurred shall be made in accordance with the presumptions set forth in Treasury Regulation Section 1.409A-1(h).

(d)The parties intend that this Agreement will be administered in accordance with Section 409A of the Code.  To the extent that any provision of this Agreement is ambiguous as to its compliance with Section 409A of the Code, the provision shall be read in such a manner so that all payments hereunder comply with Section 409A of the Code.  Each payment pursuant to this Agreement or the Restrictive Covenants Agreement is intended to constitute a separate payment for purposes of Treasury Regulation Section 1.409A-2(b)(2).  The parties agree that this Agreement may be amended, as reasonably requested by either party, and as may be necessary to fully comply with Section 409A of the Code and all related rules and regulations in order to preserve the payments and benefits provided hereunder without additional cost to either party.
(e)The Company makes no representation or warranty and shall have no liability to the Executive or any other person if any provisions of this Agreement are determined to constitute deferred compensation subject to Section 409A of the Code but do not satisfy an exemption from, or the conditions of, such Section.
8.Continuing Obligations. 
(a)Restrictive Covenants Agreement.  As a condition of employment, the Executive is required to enter into the Employee Confidentiality, Assignment, Nonsolicitation and Noncompetition Agreement, attached hereto as Exhibit A (the “Restrictive Covenants Agreement”).  The Executive acknowledges and agrees that the Executive received the Restrictive Covenants Agreement with this Agreement and at least ten (10) business days before the commencement of the Executive’s employment with the Company.  The Executive’s confidentiality and restrictive covenant obligations to bluebird bio (the “Prior Obligations”) will be or have been assigned to the Company in the Transaction, to which assignment the Executive hereby consents, and such Prior Obligations remain in full effect.  For purposes of this Agreement, the obligations in this Section 8, those contained in the Restrictive Covenants Agreement and any other agreement relating to confidentiality, assignment of inventions, or other restrictive covenants, including without limitation the Preserved Obligations, shall collectively be referred to as the “Continuing Obligations.”  
(b)Third-Party Agreements and Rights.  The Executive hereby confirms that, except for the Preserved Obligations, the Executive is not bound by the terms of any agreement with any previous employer or other party which restricts in any way the Executive’s use or disclosure of information, other than confidentiality restrictions (if any), or the Executive’s engagement in any business.  The Executive represents to the Company that the Executive’s execution of this Agreement, the Executive’s employment with the Company and the performance of the Executive’s proposed duties for the Company will not violate any obligations the Executive may have to any such previous employer or other party.  In the Executive’s work for the Company, the Executive will not disclose or make use of any information in violation of any agreements with or rights of any such previous employer or other party, and the Executive will not bring to the premises of the Company any copies or other tangible embodiments of non-public information belonging to or obtained from any such previous employment or other party.
(c)Litigation and Regulatory Cooperation.  During and after the Executive’s employment, the Executive shall cooperate fully with the Company in (i) the defense or prosecution of any claims or actions now in existence or which may be brought in the future against or on behalf of the Company which relate to events or occurrences that transpired while the Executive was employed by the Company, and (ii) the investigation, whether internal or external, of any matters about which the Company believes the Executive may have knowledge or information.  The Executive’s full cooperation in connection with such claims, actions or investigations shall include, but not be limited to, being available to meet with counsel to answer questions or to prepare for discovery or trial and to act as a witness on behalf of the Company at mutually convenient times.  During and after the Executive’s employment, the Executive also 

shall cooperate fully with the Company in connection with any investigation or review of any federal, state or local regulatory authority as any such investigation or review relates to events or occurrences that transpired while the Executive was employed by the Company.  The Company shall reimburse the Executive for any reasonable out-of-pocket expenses incurred in connection with the Executive’s performance of obligations pursuant to this Section 8(c).
(d)Relief.  The Executive agrees that it would be difficult to measure any damages caused to the Company which might result from any breach by the Executive of the Continuing Obligations, and that in any event money damages would be an inadequate remedy for any such breach.  Accordingly, the Executive agrees that if the Executive breaches, or proposes to breach, any portion of the Continuing Obligations, the Company shall be entitled, in addition to all other remedies that it may have, to an injunction or other appropriate equitable relief to restrain any such breach without showing or proving any actual damage to the Company.
9.Consent to Jurisdiction.  The parties hereby consent to the jurisdiction of the state and federal courts of the Commonwealth of Massachusetts.  Accordingly, with respect to any such court action, the Executive (a) submits to the exclusive personal jurisdiction of such courts; (b) consents to service of process; and (c) waives any other requirement (whether imposed by statute, rule of court, or otherwise) with respect to personal jurisdiction or service of process.
10.Waiver of Jury Trial.  Each of the Executive and the Company irrevocably and unconditionally WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY PROCEEDING (WHETHER BASED ON CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE EXECUTIVE’S EMPLOYMENT BY THE COMPANY OR ANY AFFILIATE OF THE COMPANY, INCLUDING WITHOUT LIMITATION THE EXECUTIVE’S OR THE COMPANY’S PERFORMANCE UNDER, OR THE ENFORCEMENT OF, THIS AGREEMENT.
11.Integration.  This Agreement constitutes the entire agreement between the parties with respect to the subject matter hereof and supersedes all prior agreements between the parties concerning such subject matter, including the Prior Agreement, provided that the Preserved Obligations remain in full force and effect.
12.Withholding; Tax Effect.  All payments made by the Company to the Executive under this Agreement shall be net of any tax or other amounts required to be withheld by the Company under applicable law.  Nothing in this Agreement shall be construed to require the Company to make any payments to compensate the Executive for any adverse tax effect associated with any payments or benefits or for any deduction or withholding from any payment or benefit.  
13.Assignment; Successors and Assigns.  Neither the Executive nor the Company may make any assignment of this Agreement or any interest in it, by operation of law or otherwise, without the prior written consent of the other; provided, however, that the Company may assign its rights and obligations under this Agreement (including the Restrictive Covenants Agreement and the Prior Obligations) without the Executive’s consent to any affiliate or to any person or entity with whom the Company shall hereafter effect a reorganization or consolidation, into which the Company merges or to whom it transfers all or substantially all of its properties or assets; provided, further that if the Executive remains employed or becomes employed by the Company, the purchaser or any of their affiliates in connection with any such transaction, then the Executive shall not be entitled to any payments, benefits or vesting pursuant to Section 5 or pursuant to Section 6 of this Agreement solely as a result of such transaction.  This Agreement shall inure to the benefit of and be binding upon the Executive and the Company, and each of the 

Executive’s and the Company’s respective successors, executors, administrators, heirs and permitted assigns.  
14.Enforceability.  If any portion or provision of this Agreement (including, without limitation, any portion or provision of any section of this Agreement) shall to any extent be declared illegal or unenforceable by a court of competent jurisdiction, then the remainder of this Agreement, or the application of such portion or provision in circumstances other than those as to which it is so declared illegal or unenforceable, shall not be affected thereby, and each portion and provision of this Agreement shall be valid and enforceable to the fullest extent permitted by law.
15.Survival.  The provisions of this Agreement shall survive the termination of this Agreement and/or the termination of the Executive’s employment to the extent necessary to effectuate the terms contained herein.
16.Waiver.  No waiver of any provision hereof shall be effective unless made in writing and signed by the waiving party.  The failure of any party to require the performance of any term or obligation of this Agreement, or the waiver by any party of any breach of this Agreement, shall not prevent any subsequent enforcement of such term or obligation or be deemed a waiver of any subsequent breach.
17.Notices.  Any notices, requests, demands and other communications provided for by this Agreement shall be sufficient if in writing and delivered in person or sent by a nationally recognized overnight courier service or by registered or certified mail, postage prepaid, return receipt requested, to the Executive at the last address the Executive has filed in writing with the Company or, in the case of the Company, at its main offices, attention of the Board.
18.Amendment.  This Agreement may be amended or modified only by a written instrument signed by the Executive and by a duly authorized representative of the Company.
19.Effect on Other Plans and Agreements.  Except for the Restrictive Covenants Agreement, in the event that the Executive is party to an agreement with the Company providing for payments or benefits under such plan or agreement and under this Agreement, the terms of this Agreement shall govern and the Executive may receive payment under this Agreement only and not both.  Further, Section 5 and Section 6 of this Agreement are mutually exclusive and in no event shall the Executive be entitled to payments or benefits pursuant to both Section 5 and Section 6 of this Agreement.  
20.Governing Law.  This is a Massachusetts contract and shall be construed under and be governed in all respects by the laws of the Commonwealth of Massachusetts, without giving effect to the conflict of laws principles thereof.  With respect to any disputes concerning federal law, such disputes shall be determined in accordance with the law as it would be interpreted and applied by the United States Court of Appeals for the First Circuit.
21.Counterparts.  This Agreement may be executed in any number of counterparts, each of which when so executed and delivered shall be taken to be an original; but such counterparts shall together constitute one and the same document.

IN WITNESS WHEREOF, the parties have executed this Agreement effective on the Effective Date.
