ARTICLE II
TRANSFER OF 2SEVENTY EMPLOYEES; GENERAL PRINCIPLES
Section 2.1    Transfer of Employment to 2seventy of Additional Employees; Post-Effective Time Transfers; Independent Contractors.
(a)    Following the date hereof, bluebird and 2seventy may cause the employment of individuals designated by bluebird who are not employed by a 2seventy Group member as of the date hereof to be transferred to a 2seventy Group member within the time period(s) designated by bluebird.
(b)    In the event that bluebird determines following the Distribution Effective Time that any individual employed outside the United States (other than an individual who the Parties intend to be a 2seventy Employee) has inadvertently become employed by a member of the 2seventy Group (due to the operation of transfer of undertakings or similar law or regulation), the Parties shall cooperate and take such actions as may be reasonably necessary in order to cause the employment of such individuals to be promptly transferred to a member of the bluebird Group.
(c)    The Parties shall cooperate and take such actions as may be reasonably necessary in order to minimize potential statutory, contractual, plan-based or other severance or similar obligations to the Parties or their Affiliates in connection with any transfers of employment described in this Section 2.1.
(d)    2seventy will determine which, if any, temporary workers, individual consultants or independent contractors who are performing service primarily related to the Oncology Business, it wishes to transfer to 2seventy, and the Parties shall use reasonable efforts to transfer the individual or to assign the applicable Contract to a member of the 2seventy Group and 2seventy shall, or shall cause a member of the 2seventy Group to, assume and perform such Contract.
Section 2.2    Assumption and Retention of Liabilities.  bluebird and 2seventy intend that employment-related Liabilities associated with bluebird Participants are to be retained or assumed by bluebird or a bluebird Group member (other than, for the avoidance of doubt, a 2seventy Group member), and employment-related Liabilities associated with 2seventy Participants are to be assumed by 2seventy or a 2seventy Group member, in each case, except as specifically set forth herein.  Accordingly, as of the Distribution Effective Time:
(a)    bluebird or the applicable member of the bluebird Group hereby retains or assumes and agrees to pay, perform, fulfill, and discharge, except as expressly provided in this Agreement, (i) all Liabilities arising under or related to bluebird Plans, (ii) all employment or service-related Liabilities with respect to (A) all bluebird Participants and (B) any individual who is, or was, an independent contractor, temporary employee, temporary service worker, consultant, freelancer, agency employee, leased employee, on-call worker, incidental worker, or non-payroll worker or in any other employment or similar relationship primarily connected to 
6

bluebird or a bluebird Group member and (iii) any Liabilities expressly transferred or allocated to bluebird or a bluebird Group member under this Agreement; and
(b)    2seventy hereby retains or assumes and agrees to pay, perform, fulfill, and discharge, except as expressly provided in this Agreement, (i) all Liabilities arising under or related to 2seventy Plans, (ii) all employment or service-related Liabilities with respect to (A) all 2seventy Participants and (B) any individual who is, or was, an independent contractor, temporary employee, temporary service worker, consultant, freelancer, agency employee, leased employee, on-call worker, incidental worker, or non-payroll worker or in any other employment or similar relationship primarily connected to 2seventy or a 2seventy Group member, including, without limitation, for both (A) and (B) hereof, any such Liabilities that may have arisen or that may be based upon events that occurred while such 2seventy Participant or other individual was employed by or otherwise provided services to bluebird or a bluebird Group member, and (iii) any Liabilities expressly transferred or allocated to 2seventy or a 2seventy Group member under this Agreement.
Section 2.3    2seventy Participation in the bluebird Plans.  Except as expressly provided in Article V of this Agreement, effective not later than the Distribution Effective Time, 2seventy and each 2seventy Group member shall cease to be a participating company in each bluebird Plan, and bluebird and 2seventy shall take all necessary action before the Distribution Effective Time to effectuate such cessation as a participating company.
Section 2.4    Sponsorship of the 2seventy Plans.  Effective no later than immediately prior to the Distribution Effective Time, bluebird and 2seventy shall take such actions (if any) as are required to cause 2seventy or a 2seventy Group member to assume sole sponsorship of, and all Liabilities with respect to, each 2seventy Plan; provided that the parties shall agree prior to the Distribution Effective Time as to the treatment of any non-ERISA or voluntary Plans.
Section 2.5    No Duplication of Benefits; Service and Other Credit.  bluebird and 2seventy shall adopt, or cause to be adopted, all reasonable and necessary amendments and procedures to prevent 2seventy Participants from receiving duplicative benefits from the bluebird Plans and the 2seventy Plans.  With respect to 2seventy Employees, each 2seventy Plan shall provide that for purposes of determining eligibility to participate, vesting, and entitlement to benefits, service prior to the Distribution Effective Time with bluebird or a bluebird Group member shall be treated as service with 2seventy or the applicable 2seventy Group member.  Such service also shall apply for purposes of satisfying any waiting periods, evidence of insurability requirements, or the application of any preexisting condition limitations under any 2seventy Plan.  Each 2seventy Plan shall, to the extent practicable, waive pre-existing condition limitations with respect to 2seventy Employees.  To the extent permitted under the applicable plan, 2seventy shall honor any deductibles incurred by 2seventy Employees and their eligible dependents under any bluebird medical plan in which they participated immediately prior to the Distribution Effective Time during the then-elapsed portion of the calendar year prior to the Distribution Effective Time for purposes of satisfying any deductibles or out-of-pocket maximums under the 2seventy Plans in which they are eligible to participate after the Distribution Effective Time in the same plan year in which such deductibles were incurred.  For 
7

the avoidance of doubt, 2seventy shall not be required to honor any co-payments incurred by 2seventy Employees or their eligible dependents under any bluebird Health and Welfare Plan for purposes of satisfying any out-of-pocket maximums under the 2seventy Plans in which they are eligible to participate after the Distribution Effective Time.
Section 2.6    Reimbursements.  From time to time after the Distribution Effective Time, the Parties shall reimburse one another, within sixty (60) days following reasonable request of the Party requesting reimbursement and the presentation by such Party of such substantiating documentation as the other Party shall reasonably request, for the cost of any Liabilities satisfied or assumed by the Party requesting reimbursement or its Affiliates that are made, pursuant to this Agreement, the responsibility of the other Party or any of its Affiliates.
Section 2.7    Approval of Plans.  Prior to the Distribution Effective Time, bluebird shall have caused 2seventy to adopt the 2seventy Stock Plan and an employee stock purchase plan intended to meet the requirements of Section 423 of the Code and the regulations promulgated thereunder (the “2seventy ESPP”) and have taken all actions as may be necessary to approve the 2seventy Stock Plan and the 2seventy ESPP in order to satisfy the applicable requirements of the Code and the applicable rules and regulations of NASDAQ.
Section 2.8    Delivery of Shares; Registration Statement.  From and after the Distribution Effective Time, bluebird shall have sole responsibility for delivery of shares of bluebird Common Stock pursuant to awards issued under a bluebird Plan in satisfaction of any obligations to deliver such shares under such bluebird Plan (including delivery to 2seventy Employees and Former 2seventy Employees) and shall do so without compensation from any 2seventy Group member.  From and after the Distribution Effective Time, 2seventy shall have sole responsibility for delivery of shares of 2seventy Common Stock pursuant to awards issued under a 2seventy Plan in satisfaction of any obligations to deliver such shares under the 2seventy Plans (including delivery to bluebird Employees and Former bluebird Employees) and shall do so without compensation from any bluebird Group member.  2seventy shall cause a registration statement on Form S-8 (or other appropriate form) to be filed with respect to such issued or issuable shares prior to the Distribution Effective Time and shall use commercially reasonable efforts to cause such registration statement to remain in effect for so long as there may be an obligation to deliver 2seventy shares under such 2seventy Plans.  bluebird shall use commercially reasonable efforts (i) to assist 2seventy in completing such registration and (ii) to cause a registration statement on Form S-8 (or other appropriate form) of bluebird to remain in effect for so long as there may be an obligation to deliver bluebird shares under any bluebird Plans.
Section 2.9    No Change in Control.  bluebird and 2seventy each hereby agree that none of the transactions contemplated by the Separation Agreement or any of the Ancillary Agreements, including this Agreement, constitutes a “change in control,” “change of control,” “sale event,” or transaction having a similar name, as applicable, within the meaning of any bluebird Plan or 2seventy Plan.
Section 2.10    Labor Relations.  To the extent required by applicable Law, the Parties shall cooperate to provide notice, engage in consultation and take any similar action which may 
8

be required on its part in connection with the Separation. The Parties hereby agree that they are not aware of any applicable labor union, work council or similar employee organization that would require notice in connection with the Separation.

9

deposited into the 2seventy Employees’ accounts under the bluebird 401(k) Plan as of the date such accounts are transferred from the trust established under the bluebird 401(k) Plan to the trust established under the 2seventy 401(k) Plan as set forth in Section 3.1(b), then bluebird and 2seventy shall cooperate to make such amendments, if any, to the bluebird 410(k) Plan and/or the 2seventy 401(k) Plan and/or to take such other actions as may be necessary or appropriate to ensure that the 2seventy Employees are given the full economic benefit of such employer matching contributions as soon as practicable following the determination of such employer matching contribution (and other employer contribution, if any) amounts.

Effective January 1, 2022, 2seventy Employees who were participating in the bluebird Health and Welfare Plans as of December 31, 2021 shall cease to participate in the bluebird Health and Welfare Plans and shall, as applicable, commence participation in the corresponding 2seventy Health and Welfare Plan in which they have enrolled.  2seventy shall cause 2seventy Employees and their covered dependents who participate in bluebird Health and Welfare Plans as of December 31, 2021 to be eligible to enroll as of January 1, 2022 in such 2seventy Health and Welfare Plans as are made available to the 2seventy Employee.  The transfer of employment from bluebird or a bluebird Group member to 2seventy or a 2seventy Group member prior to or as of the Distribution Effective Time shall not be treated as a “qualifying event” with respect to any 2seventy Employee under the bluebird Health and Welfare Plans or the 2seventy Health and Welfare Plans.
Section 4.2    Allocation of Health and Welfare Plan Liabilities.  All outstanding Liabilities relating to, arising out of, or resulting from health and welfare coverage or claims incurred by or on behalf of 2seventy Employees or their covered dependents under the bluebird Health and Welfare Plans on or before the Distribution Effective Time shall be retained by bluebird.  Any Liabilities relating to, arising out of, or resulting from health and welfare coverage or claims incurred by or on behalf of 2seventy Employees or their covered dependents under the bluebird Health and Welfare Plans following the Distribution Effective Time shall be assumed by 2seventy; provided, however, that to the extent such a Liability is covered under an insurance policy maintained with respect to a bluebird Health and Welfare Plan regardless of 
10

when the Liability arises, and such Liability is not covered under an insurance policy maintained with respect to a 2seventy Health and Welfare Plan, such Liability shall be retained by bluebird to the extent of such coverage; and provided further, however, that to the extent that bluebird receives prior to the Distribution Effective Time an invoice from a service provider billing bluebird for a service or product relating to health or welfare coverage for 2seventy Employees or their covered dependents following the Distribution Effective Time, bluebird shall be responsible for paying such invoice and 2seventy shall reimburse bluebird for any amount paid by bluebird.  For the avoidance of doubt, the working rates will be used for reimbursement for the self-insured dental.  For purposes of this Agreement, a claim shall be incurred upon the date upon which service or product giving rise to the Liability was provided.  Any payments, repayments, reimbursements or credits consisting of, or representing, dividends, demutualizations, premium refunds, rebates, subrogation or similar reimbursements, overpayments, class action recoveries, or like payments under, or relating to, any bluebird Health or Welfare Plan whenever occurring shall remain the property solely of bluebird and neither 2seventy, any 2seventy Group member nor any 2seventy Participant shall have any interest in or right to such bluebird property.
Section 4.3    Flexible Spending Plan Treatment.  Effective as of January 1, 2022, 2seventy shall establish a dependent care spending account and a medical care spending account (the “2seventy FSAs”), which 2seventy FSAs shall have terms that are substantially identical to the analogous bluebird dependent care and medical care flexible spending accounts (the “bluebird FSAs”) as in effect immediately prior to the Distribution Effective Time.  2seventy shall take all steps necessary or appropriate to allow each such 2seventy Employee to make a new election under the 2seventy FSAs effective as of January 1, 2022.

All workers’ compensation Liabilities relating to, arising out of, or resulting from any claim by 2seventy Employees or Former 2seventy Employees that result from an accident or from an occupational disease which is incurred or becomes manifest, as the case may be, on or before the Distribution Effective Time and while such individual was employed by bluebird or a bluebird Group member shall be retained by bluebird.  Any workers’ compensation Liabilities relating to, arising out of, or resulting from any claim by 2seventy Employees or Former 2seventy Employees that result from an accident or from an occupational disease which is incurred or becomes manifest, as the case may be, following the Distribution Effective Time shall be assumed by 2seventy; provided, however, that to the extent such a Liability is covered under a workers compensation insurance policy of bluebird or a bluebird Group member regardless of when the Liability arises, and such Liability is not covered under a workers compensation insurance policy of 2seventy or a 2seventy Group member, such Liability shall be retained by bluebird or a bluebird Group member to the extent of such coverage; and provided further, however, that to the extent that bluebird or a bluebird Group member, as applicable, receives prior to the Distribution Effective Time an invoice for a covered expense with respect to such Liability, bluebird shall be responsible for paying such invoice and 2seventy shall reimburse bluebird for any amount paid by bluebird.  Notwithstanding the foregoing, 2seventy shall assume worker’s compensation Liabilities to the extent they are imposed on 2seventy under applicable Law or where the injury or illness related to the Liability is aggravated or subject to further injury after the Distribution 
11

Effective Time.  A Liability which must be paid due to the existence of a deductible shall not be deemed to be covered by a workers compensation insurance policy for purposes of this Section 4.4.  Subject to the foregoing, 2seventy and each 2seventy Group member shall also be solely responsible for all workers’ compensation Liabilities relating to, arising out of, or resulting from any claim incurred for a compensable injury sustained by a 2seventy Employee that results from an accident or from an occupational disease which is incurred or becomes manifest, as the case may be, after the Distribution Effective Time.  bluebird, each bluebird Group member, 2seventy and each 2seventy Group member shall cooperate with respect to processing of claims, any notification to appropriate governmental agencies of the disposition and the issuance of new, or the transfer of existing, workers’ compensation insurance policies and claims handling contracts.

Without limiting in any manner the obligations and Liabilities of the Parties under the Tax Matters Agreement, including all withholding obligations otherwise set forth therein, bluebird, each bluebird Group member, 2seventy and each 2seventy Group member shall each bear its responsibility for payroll tax obligations and for the proper reporting to the appropriate governmental authorities of compensation earned by their respective employees after the Distribution Effective Time, including compensation related to the exercise of stock options or the vesting or exercise of other equity awards, including in instances where such equity awards are with respect to the equity of the other Party.

For the avoidance of doubt, COBRA costs will be invoiced monthly to 2seventy during the transition period, and 2seventy shall be responsible for the cost and administration of COBRA for any 2seventy Employees who are not eligible for the 2seventy Health and Welfare Plans in 2022 while continuing COBRA coverage.
Section 4.7    Vacation and Paid Time Off.

reasonable business activities.  Each Party shall ensure that such Party’s Permitted Recipients comply with these obligations.  Each Party shall notify the other promptly on discovery of any unauthorized use or disclosure of the other’s Confidential Information.
4.2      Exceptions.  The obligations of confidentiality, non-disclosure, and non-use set forth in Section 4.1 shall not apply to the extent the receiving Party (the “Recipient”) can demonstrate that the disclosed information (a) was in the public domain at the time of disclosure to the Recipient by the other Party, or thereafter entered the public domain, in each case other than as a result of actions of the Recipient or its Permitted Recipients; (b) was rightfully known by the Recipient or its Permitted Recipients (as shown by its written records) prior to the date of disclosure to the Recipient by the other Party; (c) was received by the Recipient or its Permitted Recipients on an unrestricted basis from a Third Party rightfully in possession of such information and not under a duty of confidentiality to the other Party; or (d) was independently developed by or for the Recipient or its Permitted Recipients without reference to or reliance on the Confidential Information of the other Party (as demonstrated by written records).  Notwithstanding any other provision of this Agreement, Recipient’s disclosure of Confidential Information shall not be prohibited if such disclosure:  (i) is in response to a valid order of a court or other governmental body of the U.S., provided that Recipient provides the other Party with prior written notice of such disclosure in order to permit the other Party to seek a protective order or other confidential treatment of such Confidential Information; or (ii) is otherwise required by applicable law or regulation or rules of a nationally recognized securities exchange.  Further notwithstanding any other provision of this Agreement, either Party may disclose Confidential Information of the other Party to the extent necessary to exercise the rights granted to or retained by the Recipient under this Agreement in filing or prosecuting Patent Rights, prosecuting or defending litigation or otherwise establishing rights or enforcing obligations under this Agreement.

6.2      No Early Termination.  No Party may unilaterally terminate this Agreement or any (sub)licenses granted hereunder, for any reason, including a material breach of this Agreement by the other Party, provided, however, that each Party will retain and may pursue any remedies for such breach that it may be entitled to in a court of law or equity, including monetary damages and injunctive and equitable relief.
Article 7– MISCELLANEOUS PROVISIONS
7.1      Relationship to Separation Agreement.  The Parties agree and acknowledge that this Agreement is a Transaction Agreement for purposes of the Separation Agreement and the Parties intend and agree that this Agreement shall be subject to the terms and conditions set forth in the Separation Agreement that are made applicable thereby to Transaction Agreements.
7.2      Waivers.  The delay or failure of either Party to exercise or enforce any of its rights under this Agreement will not constitute, or be deemed to be, a waiver of those rights, nor will any single or partial exercise of any such rights preclude any other or further exercise thereof or the exercise of any other right.  No waiver of any provision of this Agreement will be effective unless it is in writing and signed by the Party against which it is being enforced.
7.3      Assignment.  No Party may assign any rights or delegate any obligations arising under this Agreement (excluding, for avoidance of doubt, sublicenses granted in accordance herewith), in whole or in part, directly or indirectly, without the prior written consent of the other Party (such consent not to be unreasonably withheld, conditioned or delayed), and any attempt to so assign any rights or delegate any obligations arising under this Agreement without such consent shall be void.  Notwithstanding the foregoing, no such consent shall be required for any such assignment or delegation (i) with respect to bluebird, to a Subsidiary of bluebird (so long as such Subsidiary remains a Subsidiary of bluebird), (ii) with respect to 2seventy, to a Subsidiary of 2seventy (so long as such Subsidiary remains a Subsidiary of 2seventy) or (iii) to a bona fide Third Party in connection with a merger, reorganization, consolidation or the sale of all or substantially all the assets of a Party so long as the resulting, surviving or transferee entity
8

assumes all the obligations of the assigning Party by operation of Law or pursuant to an agreement in form and substance reasonably satisfactory to the non-assigning Party; provided, however, that in the case of each of the preceding clauses (i) and (ii), no assignment permitted by this Section 7.3 shall release the assigning Party from liability for the full performance of its obligations under this Agreement.
7.4      Successors and Assigns.  The provisions of this Agreement and the obligations and rights hereunder shall be binding upon, inure to the benefit of and be enforceable by (and against) the Parties and their respective successors (whether by merger, acquisition of assets or otherwise) and permitted assigns.
7.5      Payment Terms.
(a)Any amount to be paid or reimbursed by a Party to the other Party under this Agreement shall be paid or reimbursed hereunder within sixty (60) days after presentation of an invoice or a written demand therefor, in either case setting forth, or accompanied by, reasonable documentation or other reasonable explanation supporting such amount.
(b)Any amount not paid when due pursuant to this Agreement (and any amount billed or otherwise invoiced or demanded and properly payable that is not paid within sixty (60) days of such bill, invoice or other demand) shall bear interest at a rate per annum equal to the Prime Rate, from time to time in effect, plus two percent (2%), calculated for the actual number of days elapsed, accrued from the date on which such payment was due up to the date of the actual receipt of payment.
(c)Without the consent of the Party receiving any payment under this Agreement specifying otherwise, all payments to be made by either bluebird or 2seventy under this Agreement shall be made in U.S. dollars.
7.6      Subsidiaries. Each of the Parties shall cause to be performed, and hereby guarantees the performance of, all actions, agreements and obligations set forth herein to be performed by any Subsidiary of such Party or by any entity that becomes a Subsidiary of such Party at or after the Effective Date in each case to the extent such Subsidiary remains a Subsidiary of the applicable Party.
7.7      Third Party Beneficiaries. This Agreement is solely for the benefit of the Parties and shall not be deemed to confer upon any Person other than the Parties any remedy, claim, liability, reimbursement, cause of Action or other right beyond any that exist without reference to this Agreement.
7.8      Titles and Headings. Titles and headings to sections herein are inserted for the convenience of reference only and are not intended to be a part of or to affect the meaning or interpretation of this Agreement.
7.9      Governing Law.  This Agreement will be governed by, construed and interpreted in accordance with the Laws of the State of Delaware, without reference to principles of conflicts of Laws.  Each Party irrevocably consents to the exclusive jurisdiction, forum and venue of the Delaware Court of Chancery (and if the Delaware Court of Chancery shall be unavailable, any
9

Delaware State court or the federal court sitting in the State of Delaware) over any and all claims, disputes, controversies or disagreements between the Parties under or related to this Agreement or any of the transactions contemplated hereby, including their execution, performance or enforcement, whether in contract, tort or otherwise.  Each of the Parties hereby agrees that it shall not assert, and shall hereby waive, any claim or right or defense that it is not subject to the jurisdiction of such courts, that the venue is improper, that the forum is inconvenient or any similar objection, claim or argument.
7.10      Severability.  In the event any one or more of the provisions contained in this Agreement should be held invalid, illegal or unenforceable in any respect, the validity, legality and enforceability of the remaining provisions contained herein and therein shall not in any way be affected or impaired thereby.  The Parties shall endeavor in good-faith negotiations to replace the invalid, illegal or unenforceable provisions with valid provisions, the economic effect of which comes as close as possible to that of the invalid, illegal or unenforceable provisions.
7.11      Interpretation.  The Parties have participated jointly in the negotiation and drafting of this Agreement.  This Agreement shall be construed without regard to any presumption or rule requiring construction or interpretation against the Party drafting or causing any instrument to be drafted.
7.12      No Duplication; No Double Recovery.  Nothing in this Agreement is intended to confer to or impose upon any Party a duplicative right, entitlement, obligation or recovery with respect to any matter arising out of the same facts and circumstances.
7.13      No Waiver.  No failure to exercise and no delay in exercising, on the part of any Party, any right, remedy, power or privilege hereunder shall operate as a waiver hereof or thereof; nor shall any single or partial exercise of any right, remedy, power or privilege hereunder or thereunder preclude any other or further exercise thereof or the exercise of any other right, remedy, power or privilege.
