By way of example, in a given calendar year, if the aggregate annual Net Sales for a Licensed Product for ROW Administration is [***], the following royalty payment would be payable for those Net Sales under this Section 11.3(a): [***].

The Parties acknowledge and agree that for the purposes of calculating royalties under this Section 11.3(a), the country of sale for Licensed Product will be deemed to be the country in which such Licensed Product is administered to a patient.

As provided in Section 11.1(b), if Celgene (or its Sublicensee) is required to pay to a Third Party under any New In-License or Co-Co License or any Celgene Licensed Product In-License, any royalties for Commercialization of Licensed Product for ROW Administration, or if Celgene or its Sublicensee, in its reasonable judgment, is required to obtain a license from any Third Party under any Patent Covering Licensed Product in order to Develop or Commercialize such Licensed Product for ROW Administration, and if Celgene (or its Sublicensee) is required to pay to such Third Party under such license any royalties, and the infringement of such Patent cannot reasonably be avoided by Celgene or its Sublicensee, or if Celgene (or its Sublicensee) is required by a court of competent jurisdiction to pay royalties or lost profits to a Third Party based on a Patent as a result of the such Commercialization (and the infringement of such Patent cannot reasonably be avoided by Celgene or its Sublicensee), then the amount of Celgene’s royalty obligations under this Section 11.3 will be reduced by [***] of the amount of such royalties paid to such Third Party, provided however, that the royalties payable under Section 11.3(a) will not be reduced in any such event below [***] of the amounts set forth in Section 11.3(a) (but as may be further reduced pursuant to Section 11.3(c) or 11.3(e)) for each royalty tier.

Any royalties payable under any Applicable New In-Licenses, Celgene Licensed

Product In-Licenses and Co-Co Licenses may be deducted under this Section 11.3(d) from royalties owed to Bluebird.

Prior to Celgene or its Sublicensee exercising its reasonable judgment under this Section 11.3(d), Celgene will provide Bluebird with written notice of a potential need to obtain any license from Third Parties. The Parties will discuss the best course of action to resolve such potential license requirement(s). For clarity, the Parties acknowledge and agree that, notwithstanding anything in this CCPS Agreement to the contrary, no royalties or other amounts payable by Celgene (or its Sublicensee) to a Third Party with respect to Licensed Product for U.S. Administration may act to reduce the amount of Celgene’s royalty obligations under this Section 11.3.

Each Party will exercise its ownership rights in and to such Joint IP, including the right to license and sublicense or otherwise to exploit, transfer or encumber its ownership interest, without an accounting or obligation to, or consent required from, the other Party, but subject to the licenses hereunder and the other terms and conditions of this CCPS Agreement, including Section 10.4. At the reasonable written request of a Party, the other Party will in writing grant such consents and confirm that no such accounting is required to effect the foregoing regarding Joint IP. Each Party, for itself and on behalf of its Affiliates, licensees and sublicenses, and employees, subcontractors, consultants and agents of any of the foregoing, hereby assigns (and to the extent such assignment can only be made in the future hereby agrees to assign), to the other Party a joint and undivided interest in and to all Joint IP. The Prosecution and Maintenance, and the enforcement and defense, of any Patents within Joint IP will be jointly managed by the Parties on mutually agreeable terms to be entered into by the Parties at the time any such Patents are first filed, provided that (i) all recoveries and Patent Costs arising from the enforcement or defense of any Patents within Joint IP, absent further agreement, will be shared by the Parties in accordance with Section 14.2 (provided that sufficient advance written notice of any such Patent Costs is given to the Party not incurring same) and (ii) Patent Costs incurred in connection with the Prosecution and Maintenance of Patents within Joint IP will be apportioned as set forth in Sections 13.1 and 13.3, provided that in each case ((i) and (ii)), and all recoveries and Patent Costs arising from those activities, absent further agreement, will be shared equally by the Parties (provided that sufficient advance written notice of any such Patent Costs is given to the Party not incurring same), provided that if either Party elects not to pay any such Patent Costs for any such Patent, the Parties will meet and agree upon an equitable way to treat such Patent.

12.3 Inventorship. Inventorship determination for all Patents worldwide arising from any Know-How discovered, created, conceived, developed or reduced to practice by or on behalf of the Parties under or in connection with this CCPS Agreement and thus the ownership thereof will be made in accordance with applicable United States patent Laws.

12.4 Allocation. Notwithstanding Sections 12.1 through 12.3, the Patent Committee may allocate ownership of a particular item of intellectual property to improve the prospects of obtaining patent protection with respect to such item of intellectual property, even if such allocation is not in accordance with the terms of Sections 12.1 through 12.3, so long as the Parties mutually agree to such allocation.

13. Patent Prosecution and Maintenance.

13.1 Generally. Subject to Sections 13.2, 13.3 and 13.5, each Party will have the sole right to Prosecute and Maintain Patents within its respective Licensed IP. Bluebird will use commercially reasonable efforts to, where applicable and permitted under applicable Law and upon Celgene’s reasonable request, separate parent Patent applications within the Bluebird Licensed IP into one or more separate Patent applications for Specific Patents, where doing so would not reasonably be expected to materially harm any Patent within the Bluebird Licensed IP or other Patents owned by Bluebird or its Affiliates, provided that the foregoing limitation will not apply to Bluebird Licensed IP that is Collaboration IP. [***].

13.2 Input. Subject to Section 13.5, Each Party will regularly provide the other with copies of all applications for Patents within its respective Licensed IP, and all other material submissions and correspondence with any patent authorities regarding such Patents, in sufficient time to allow for review and comment by the other Party. In addition, each Party will provide the other Party and its counsel with an opportunity to consult with such Party and its counsel regarding Prosecution and Maintenance of any such Patents within the Field, and such Party will consider in good faith all such comments timely made by such other Party and its counsel. In the event of any disagreement between the Parties, the licensor Party will have the final decision-making authority with respect to the matter involved as long as the licensor Party acts in good faith.

13.3 Specific Patents. Subject to Section 13.5, for any Patent within the Bluebird Licensed IP [***] (each “Specific Patent”), the following will apply: upon Celgene’s written request, and provided that Bluebird reasonably agrees with Celgene that the following Prosecution and Maintenance activities would not materially harm any other Patent within the Bluebird Licensed IP or other Patents owned by Bluebird or its Affiliates (other than Collaboration IP), Celgene will control the Prosecution and Maintenance of the Specific Patents, and notwithstanding anything in Section 13.1 to the contrary, Celgene will be solely responsible for the payment of all related Patent Costs. In addition, Celgene will provide Bluebird and its counsel with an opportunity to (i) consult with Celgene and its counsel regarding Prosecution and Maintenance of any such Specific Patents, (ii) comment substantively on the Prosecution and Maintenance of such Specific Patents prior to taking any material action, and Celgene will include or reflect all reasonable comments timely made by Bluebird and its counsel. Celgene acknowledges and agrees that Bluebird may grant similar rights to other exclusive Third Party licensees under any Patent within the Bluebird Licensed IP that has claims Covering only a product that is not a Licensed Product (or its manufacture or use) and no other product (or its manufacture or use), other than Specific Patents. If the Parties cannot agree whether or not any Patent within the Bluebird Licensed IP is a Specific Patent, or if Bluebird claims that the foregoing Prosecution and Maintenance activities would materially harm any other Patent within the Bluebird Licensed

IP or other Patents owned by Bluebird or any of its Affiliates, either of the Parties may refer such dispute to a mutually agreeable, disinterested, conflict-of-interest-free individual not affiliated or consulting with either Party and who has at least fifteen (15) years of patent prosecution experience in the pharmaceutical field. Any such arbitration will be conducted under the then-current rules of the American Arbitration Association, and the decision of the arbitrator will be final.

13.4 Election Not to Prosecute or Maintain or Pay Patent Costs. Subject to Section 13.5, if a Party elects not (i) to Prosecute or Maintain any Patents within its respective Licensed IP in any particular country before the applicable filing deadline or continue such activities once filed in a particular country, or (ii) to pay the Patent Costs associated with Prosecution or Maintenance of any Patents within the Licensed IP as required by Section 13.1, then in each such case such first Party will so notify the other Party, promptly in writing and in good time to enable any deadlines by which an action must be taken to preserve such Patent in such country to be met, in [***]. Upon receipt of each such notice by such first Party, such other Party will have the right, but not the obligation, to notify such first Party in writing on a timely basis that such other Party will continue the Prosecution or Maintenance of such Patent on terms the Parties shall mutually agree; it being understood that only U.S. Patents controlled by Celgene will be subject to this sentence. Notwithstanding the foregoing, upon receipt of each such notice by Bluebird, Celgene will have the right, but not the obligation, to notify Bluebird in writing on a timely basis that Celgene will assume control of the Prosecution or Maintenance of such Patent within the Bluebird Licensed IP, and bear the Patent Costs thereafter incurred by Celgene with respect thereto. In addition, Celgene will provide Bluebird and its counsel with an opportunity to (i) consult with Celgene and its counsel regarding Prosecution and Maintenance of any such Patents, (ii) comment substantively on the Prosecution and Maintenance of such Patents prior to taking any material action, and Celgene will include or reflect all reasonable comments timely made by Bluebird and its counsel. If after making such election, Celgene elects not to pay the Patent Costs associated with Prosecution or Maintenance of any such Patent, then in each such case Celgene will so notify Bluebird and on the ninetieth (90th) day after Bluebird’s receipt of such notice such Patent will no longer be licensed to Celgene hereunder and will no longer be included within the “Bluebird Licensed IP” hereunder.

13.5 Third Party Rights. To the extent that a Third Party licensor of a Party has retained any right to Prosecute or Maintain any Patent within such Party’s Licensed IP licensed to the other Party hereunder, or otherwise be involved in such activities, such Party will use commercially reasonable efforts to cause such Third Party licensor to take the actions specified by this Section 13 (including Sections 13.6 and 13.7) in a manner consistent with the in-license applicable thereto, but such Party will not be deemed to be in breach of its obligations under this Section 13 if, after using such commercially reasonable efforts, it is unable to comply with such obligations because of actions taken or not taken by such Third Party licensor.

13.6 Patent Extensions. Subject to the remainder of this Section 13.6, if any election for patent term restoration, adjustment or extension, supplemental protection certificate or any of their equivalents may be made with respect to any Patent within the Licensed IP, after consultation through the JGC. If the Parties are not able to reach mutual agreement, (i) Celgene will have the

sole right to make the final decision whether or not to seek such patent term restoration, adjustment or extension, supplemental protection certificate or any of their equivalents with respect to Specific Patents and Patents within the Collaboration IP licensed to Celgene hereunder and the Celgene Licensed IP, and (ii) Bluebird will have the sole right to make the final decision whether or not to seek such patent term restoration, adjustment or extension, supplemental protection certificate or any of their equivalents with respect to all other Patents within the Bluebird Licensed IP.

13.7 Regulatory Exclusivity Periods. With respect to any Patent listings required for any Regulatory Exclusivity Periods for Product, the Parties will mutually agree on which Patents within the Licensed IP to list, provided that if the Parties are not able to agree, Celgene will have the right to make the final decision, and provided further that the exercise of such right by Celgene will not increase or otherwise change the rights or obligations of the Parties hereunder.

13.8 Cooperation. Each Party will reasonably cooperate with the other Party in the Prosecution and Maintenance of Patents within the Licensed IP. Such cooperation includes promptly executing all documents, or requiring inventors, subcontractors, employees and consultants and agents of such Party and its Affiliates and Sublicensees to execute all documents, as reasonable and appropriate so as to enable the Prosecution and Maintenance of any such Patents in any country.

13.9 Patent Marking. For Licensed Product for U.S. Administration, the JGC will determine the Patent marking requirements in accordance with applicable Law. For Licensed Product for ROW Administration, Celgene will ▇▇▇▇, and will cause all other Selling Parties to ▇▇▇▇, Product with all Patents within the Bluebird Licensed IP in accordance with applicable Law, which marking obligation will continue for as long as (and only for as long as) required under applicable Law.

13.10 Common Interest Disclosures. With regard to any information or opinions disclosed pursuant to this CCPS Agreement by one Party to the other Party regarding Prosecution and Maintenance of Patent within the Licensed IP, or enforcement of intellectual property and/or technology by or against Third Parties, Bluebird and Celgene agree that they have a common legal interest in determining the ownership, scope, validity and/or enforcement of the Licensed IP, and whether, and to what extent, Third Party intellectual property rights may affect the conduct of the Development and Commercialization of any Licensed Product, and have a further common legal interest in defending against any actual or prospective Third Party claims based on allegations of misuse or infringement of intellectual property rights relating to the Development or Commercialization of any Licensed Product. Accordingly, the Parties agree that all such information and materials obtained by the Parties from each other will be used solely for purposes of the Parties’ common legal interests with respect to the conduct of the Agreement. All such information and materials will be treated as protected by the attorney-client privilege, the work product privilege, and any other privilege or immunity that may otherwise be applicable. By sharing any such information and materials, neither Party intends to waive or limit any privilege or immunity that may apply to the shared information and materials. Neither Party will have the authority to waive any privilege or immunity on behalf of the other Party

without such other Party’s prior written consent, nor will the waiver of privilege or immunity resulting from the conduct of one Party be deemed to apply against any other Party. This Section 13.10 will be subject to any right granted by either Party to any Third Party, provided that the grant of such right to such Third Party does not conflict with the other Party’s rights or the first Party’s obligations under this CCPS Agreement.

14. Patent Enforcement and Defense.

14.1 Notice. Each Party will promptly notify, in writing, the other Party upon learning of any actual or suspected Competitive Infringement of any Patents within the Licensed IP by a Third Party, or of any claim of invalidity, unenforceability, or non-infringement of any Patents within the Licensed IP, and will, along with such notice, supply the other Party with any evidence in its possession pertaining thereto. For purposes of this CCPS Agreement, “Competitive Infringement” means any allegedly infringing activity in the Field (which, for the purposes of this definition, will include all indications and will not be limited to cancer) with respect to a Patent within the Licensed IP, which activity (i) falls within the scope then in effect of the licenses granted by Bluebird to Celgene as set forth in Sections 10.1 and 10.2, (ii) is subject to Section Error! Reference source not found., or (iii) would be competitive with a Licensed Product and targets the same Target Antigen as such Licensed Product.

14.2 Enforcement and Defense.

[***].

15. Confidentiality.

The Parties acknowledge and agree that terms of this CCPS Agreement and all Materials, ideas and information of any kind, whether in written, oral, graphical, machine-readable or other form, whether or not marked as confidential or proprietary, which are transferred, disclosed or made available by a Party or at the request of a Party, including any of the foregoing of Third Parties, will be subject to the provisions of Section 8 of the Master Collaboration Agreement. The Parties agree to issue a joint press release promptly following the CCPS Agreement Effective Date. A redacted version of this CCPS Agreement will be agreed to by the Parties and shall be consistent with the corresponding redacted version of this CCPS Agreement in such manner as is provided in Section 8.3 of the Master Collaboration Agreement.

The Parties recognize that each Party may perform some or all of its obligations under this CCPS Agreement through Affiliates and permitted subcontractors provided, however, that each Party will remain responsible and liable for the performance by its Affiliates and permitted subcontractors and will cause its Affiliates and permitted subcontractors to comply with the provisions of this CCPS Agreement in connection therewith.

16.7 Indemnification.

(a)Indemnification by Celgene. Celgene will indemnify Bluebird, its Affiliates and their respective directors, officers, employees, Third Party licensors and agents, and their respective successors, heirs and assigns (collectively, “Bluebird Indemnitees”), and defend and save each of them harmless, from and against any and all losses, damages, liabilities, costs and expenses (including reasonable attorneys’ fees and expenses) (collectively, “Losses”) in connection with any and all suits, investigations, claims or demands of Third Parties (collectively, “Third Party Claims”) against the Bluebird Indemnitees arising from or occurring as a result of: (i) the material breach by Celgene of any term of this CCPS Agreement; (ii) any gross negligence or willful misconduct on the part of Celgene in performing its obligations under this CCPS Agreement; (iii) the Development or Commercialization by or on behalf of Celgene or any of its Affiliates or Sublicensees of Elected Candidate or Licensed Product for ROW Administration, and (iv) [***], except in each case for those Losses for which Bluebird has an obligation to indemnify Celgene pursuant to Section 16.7(b), as to which Losses each Party will indemnify the other to the extent of their respective liability; provided, however, that Celgene will not be obligated to indemnify Bluebird Indemnitees for any Losses to the extent that such Losses arise as a result of gross negligence or willful misconduct on the part of an Bluebird Indemnitee.

(b)Indemnification by Bluebird. Bluebird will indemnify Celgene, its Affiliates and their respective directors, officers, employees and agents, and their respective successors, heirs and assigns (collectively, “Celgene Indemnitees”), and defend and save each of them harmless, from and against any and all Losses in connection with any and all Third Party Claims against the Celgene Indemnitees arising from or occurring as a result of: (i) the material breach by Bluebird of any term of this CCPS Agreement; (ii) any gross negligence or willful misconduct on the part of Bluebird in performing its obligations under this CCPS Agreement; or (iii) the Development by or on behalf of Bluebird or any of its Affiliates or Sublicensees of Elected Candidate or Licensed Product, except in each case for those Losses for which Celgene has an obligation to indemnify Bluebird pursuant to Section 16.7(a), as to which Losses each Party will indemnify the other to the extent of their respective liability for the Losses; provided, however, that Bluebird will not be obligated to indemnify the Celgene Indemnitees for any Losses to the extent

that such Losses arise as a result of gross negligence or willful misconduct on the part of a Celgene Indemnitee.

(c)Notice of Claim. All indemnification claims provided for in Sections 16.7(a) and 16.7(b) will be made solely by such Party to this CCPS Agreement (the “Indemnified Party”). The Indemnified Party will promptly notify the indemnifying Party (an “Indemnification Claim Notice”) of any Losses or the discovery of any fact upon which the Indemnified Party intends to base a request for indemnification under Section 16.7(a) and 16.7(b), but in no event will the indemnifying Party be liable for any Losses that result from any delay in providing such notice. Each Indemnification Claim Notice must contain a description of the claim and the nature and estimated amount of such Loss (to the extent that the nature and amount of such Loss is known at such time). The Indemnified Party will furnish promptly to the indemnifying Party copies of all papers and official documents received in respect of any Losses and Third Party Claims.

(d)Defense, Settlement, Cooperation and Expenses.

(i)Control of Defense. At its option, the indemnifying Party may assume the defense of any Third Party Claim by giving written notice to the Indemnified Party within thirty (30) days after the indemnifying Party’s receipt of an Indemnification Claim Notice, provided however that (A) the Third Party Claim solely seeks monetary damages and (B) the indemnifying Party expressly agrees in writing that as between the indemnifying Party and the Indemnified Party, the indemnifying Party will be solely obligated to satisfy and discharge the Third Party Claim in full and is able to reasonably demonstrate that it has sufficient financial resources (the matters described in (A) and (B), the “Litigation Conditions”). The assumption of the defense of a Third Party Claim by the indemnifying Party will not be construed as an acknowledgment that the indemnifying Party is liable to indemnify the Indemnified Party in respect of the Third Party Claim, nor will it constitute a waiver by the indemnifying Party of any defenses it may assert against the Indemnified Party’s claim for indemnification. Upon assuming the defense of a Third Party Claim, the indemnifying Party may appoint as lead counsel in the defense of the Third Party Claim any legal counsel selected by the indemnifying Party (the indemnifying Party will consult with the Indemnified Party with respect to a possible conflict of interest of such counsel retained by the indemnifying Party). The Indemnified Party may, at any time, assume the defense of a Third Party Claim if at any time the Litigation Conditions are not satisfied with respect to such Claim. In the event the indemnifying Party assumes the defense of a Third Party Claim, the Indemnified Party will immediately deliver to the indemnifying Party all original notices and documents (including court papers) received by the Indemnified Party in connection with the Third Party Claim. Should the indemnifying Party assume the defense of a Third Party Claim, except as provided in Section 16.7(d)(ii) the indemnifying Party will not be liable to the Indemnified Party for any legal costs or expenses subsequently incurred by such Indemnified Party in connection with the analysis, defense or settlement of the Third Party Claim. In the event that it is ultimately determined that the indemnifying Party is not obligated to indemnify, defend or hold harmless the Indemnified Party from and against the Third Party Claim, the Indemnified Party will reimburse the indemnifying Party for any and all costs and expenses

(including attorneys’ fees and costs of suit) and any Third Party Claims incurred by the indemnifying Party in its defense of the Third Party Claim.

(ii)Right to Participate in Defense. Without limiting Section 16.7(d)(i), any Indemnified Party will be entitled to participate in, but not control, the defense of such Third Party Claim and to employ counsel of its choice for such purpose; provided, however, that such employment will be at the Indemnified Party’s own cost and expense unless (i) the employment thereof has been specifically authorized by the indemnifying Party in writing, (ii) the indemnifying Party has failed to assume the defense and employ counsel in accordance with Section 16.7(d)(i) (in which case the Indemnified Party will control the defense), (iii) the interests of the Indemnified Party and the indemnifying Party with respect to such Third Party Claim are sufficiently adverse to prohibit the representation by the same counsel of both Parties under applicable Law, ethical rules or equitable principles, or (iv) the indemnifying Party no longer satisfies the Litigation Conditions, in which case the indemnifying Party will assume [***] of any such costs and expenses of counsel for the Indemnified Party.

(iii)Settlement. With respect to any Third Party Claims that relate solely to the payment of money damages in connection with a Third Party Claim and that will not result in the Indemnified Party’s becoming subject to injunctive or other relief or otherwise adversely affecting the business of the Indemnified Party in any manner, and as to which the indemnifying Party will have acknowledged in writing the obligation to indemnify the Indemnified Party hereunder, and subject to the Litigation Conditions being satisfied, the indemnifying Party will have the sole right to agree to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss, on such terms as the indemnifying Party, in its sole discretion, will deem appropriate. With respect to all other Losses in connection with Third Party Claims, where the indemnifying Party has assumed the defense of the Third Party Claim in accordance with Section 16.7(d)(i), the indemnifying Party will have authority to agree to the entry of any judgment, enter into any settlement or otherwise dispose of such Loss provided it obtains the prior written consent of the Indemnified Party (such consent not to be unreasonably withheld, delayed or conditioned). The indemnifying Party will not be liable for any settlement or other disposition of a Loss by an Indemnified Party that is reached without the prior written consent of the indemnifying Party. Regardless of whether the indemnifying Party chooses to defend or prosecute any Third Party Claim, no Indemnified Party will admit any liability with respect to or settle, compromise or discharge, any Third Party Claim without the prior written consent of the indemnifying Party, such consent not to be unreasonably withheld, delayed or conditioned.

(iv)Cooperation. If the indemnifying Party chooses to defend or prosecute any Third Party Claim, the Indemnified Party will, and will cause each other Indemnified Party to, cooperate in the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses and attend such conferences, discovery proceedings, hearings, trials and appeals as may be reasonably requested in connection therewith. Such cooperation will include access during normal business hours afforded to indemnifying Party to, and reasonable retention by the Indemnified Party of, records and information that are reasonably relevant to such Third Party Claim, and making Indemnified Parties and other employees and agents available on a mutually convenient basis to provide additional information and explanation of any material

provided hereunder, and the indemnifying Party will reimburse the Indemnified Party for all its reasonable out-of-pocket costs and expenses in connection therewith.

(v)Costs and Expenses. Except as provided above in this Section 16.7(d), the costs and expenses, including attorneys’ fees and expenses, incurred by the Indemnified Party in connection with any claim will be reimbursed on a calendar quarter basis by the indemnifying Party, without prejudice to the indemnifying Party’s right to contest the Indemnified Party’s right to indemnification and subject to refund in the event the indemnifying Party is ultimately held not to be obligated to indemnify the Indemnified Party.

16.8 Insurance. Each Party will maintain at its sole cost and expense, an adequate liability insurance or self-insurance program (including product liability insurance) to protect against potential liabilities and risk arising out of activities to be performed under this CCPS Agreement, and any agreement related hereto and upon such terms (including coverages, deductible limits and self-insured retentions) as are customary in the U.S. pharmaceutical industry for the activities to be conducted by such Party under this CCPS Agreement. Subject to the preceding sentence, such liability insurance or self-insurance program will insure against all types of liability, including personal injury, physical injury or property damage arising out of the manufacture, sale, use, distribution or marketing of Licensed Product. The coverage limits set forth herein will not create any limitation on a Party’s liability to the other under this CCPS Agreement.

16.9 U.S. Administration Liabilities. In the event that either Party (i) incurs any Losses in connection with a Third Party Claim for personal injury or death caused by the use of Licensed Product for U.S. Administration, or (ii) is required to make payments to any Third Party in order to acquire a license or other rights under Patents or Know-How necessary for the Development, Manufacture or Commercialization of Licensed Product for U.S. Administration (collectively, “U.S. Administration Liabilities”), such U.S. Administrative Losses arising from or occurring as a result of the performance, in good faith, of the Development, Manufacture or Commercialization of Licensed Product for U.S. Administration in accordance with this CCPS Agreement will be charged to such Party’s Operating Profit or Loss under the Profit & Loss Share, provided that Operating Profit or Loss will not include U.S. Administration Liabilities of a Party or its Affiliates: (1) that are caused by a breach of this CCPS Agreement by such Party or its Affiliates; (2) incurred with respect to or allocable to products other than Licensed Product for U.S. Administration; or (3) that are subject to indemnification by such Party pursuant to Section 16.7 (and for clarity, if a Third Party makes a Third Party Claim directly against Bluebird (or any of its Affiliates) or Celgene (or any of its Affiliates), respectively, that would otherwise be indemnified by Bluebird or Celgene, respectively, if such Third Party Claim had been made against the other Party (or any of its Affiliates), then U.S. Administration Liabilities incurred by Bluebird or Celgene in connection with such direct Third Party Claim will not be included in the calculation of Operating Profit or Loss).

17. Term and Termination.

17.1 Term. This CCPS Agreement will commence as of the CCPS Agreement Effective Date and, unless sooner terminated in accordance with the terms hereof or by mutual written consent,

will continue on a country-by-country basis, until there are no more payments owed one or the other Party on Licensed Product in such country (the longest such period of time for any Licensed Product hereunder, the “CCPS Agreement Term”); for clarity, unless sooner terminated in accordance with the terms hereof or by mutual written consent, this CCPS Agreement Term will continue in all events until Licensed Product is no longer being Developed or Commercialized in the United States. Upon there being no more such payments hereunder for any such Licensed Product in such country (other than the United States), the licenses contained in Section 10.1 will become fully paid up and will remain exclusive with respect to such Licensed Product in such country.

17.2 Termination by Bluebird.

(a)Breach. Bluebird will have the right to terminate this CCPS Agreement in full upon delivery of written notice to Celgene in the event of any material breach by Celgene of any terms and conditions of this CCPS Agreement in a manner that fundamentally frustrates the transactions contemplated by this CCPS Agreement, provided that such termination will not be effective if such breach, has been cured within [***] after written notice thereof is given by Bluebird to Celgene specifying the nature of the alleged breach (or, if such default cannot be cured within such [***] after such notice if Celgene commences actions to cure such default within such [***] and thereafter diligently continues such actions, but fails to cure the default by the end of such [***]; provided, however, that to the extent such material breach involves the failure to make a payment when due, such breach must be cured within [***] after written notice thereof is given by Bluebird to Celgene.

(b)[***].

(c)Termination of the Profit & Loss Share. Bluebird will have the right to terminate the Profit & Loss Share by delivering written notice to Celgene, such termination to be effective [***] following the date of such notice. Promptly following such notice, the Parties will enter into a license agreement with respect to the United States and the ROW, which agreement will be substantially identical to the License Agreement, with such changes that the Parties may, acting reasonably, mutually agree are required in order to address any specific facts or circumstances existing at the time of such termination. The Parties will enter into such license agreement no later than the effective date of such termination and, if such license agreement is not entered into prior the expiration of such [***], upon execution, the effective date of such license agreement will be deemed to be the effective date of such termination. For clarity, (i) termination of the Profit & Loss Share pursuant to this Section 17.2(c) will not release Bluebird from any obligation or liability which, at the time of the effective date of such termination, has already accrued to Celgene or which is attributable to a period prior to the effective date of such termination, and (ii) any events that have already occurred before the effective date of such termination (such as achievement of any milestones) will not trigger any payment obligation by Celgene to Bluebird under such executed license agreement (other than, for clarity, the Milestone Payment based on the Pivotal Study if not already paid or accrued under this CCPS Agreement).

17.3 Termination by Celgene.

(a)Breach. Celgene will have the right to terminate this CCPS Agreement in full upon delivery of written notice to Bluebird in the event of any material breach by Bluebird of any terms and conditions of this CCPS Agreement in a manner that fundamentally frustrates the transactions contemplated by this CCPS Agreement, provided that such termination will not be effective if such breach has been cured within [***] after written notice thereof is given by Celgene to Bluebird specifying the nature of the alleged breach (or, if such default cannot be cured within such [***], within [***] after such notice if Bluebird commences actions to cure such default within such [***] and thereafter diligently continues such actions, but fails to cure the default by the end of such [***]).

(b)Discretionary Termination. Beginning with [***], Celgene will have the right to terminate this CCPS Agreement in full, at its discretion for any reason, by delivering written notice to Bluebird, such termination to be effective [***] following the date of such notice.

(c)[***].

(d)Alternative to Termination Under Section 17.3(a). If Celgene has the right to terminate this CCPS Agreement under Section 17.3(a) or 17.3(c) (including expiration of all applicable cure periods thereunder), in lieu of exercising such termination right, Celgene may elect once by written notice to Bluebird before the end of such applicable cure period to have this CCPS Agreement continue in full force and effect and instead have, starting immediately after the end of such applicable cure period, any future Milestone Payments set forth in Section 11.2(b) and the royalty rates set forth in the table set forth in Section 11.3(a) be reduced by [***], provided that such reduction will not apply if such future Milestone Payments and royalty rates have already been reduced pursuant to Section 11.4(c) of the Master Collaboration Agreement.

17.4 Effects of Termination or Expiration. Upon termination (but not expiration pursuant to Section 17.1) of this CCPS Agreement for any reason:

(a)Wind Down. Celgene will responsibly wind-down, in accordance with accepted pharmaceutical industry norms and ethical practices, any on-going clinical studies for which it has responsibility hereunder in which patient dosing has commenced or, if reasonably practicable and requested by Bluebird, allow Celgene, its Affiliates or its Sublicensees to complete such trials. Celgene will be responsible for any costs associated with such wind-down. Bluebird will pay all costs incurred by either Party to complete such studies should Bluebird request that such studies be completed.

(b)Sublicenses. A termination of this CCPS Agreement will not automatically terminate any sublicense granted by Celgene pursuant to Section 10.3 for Commercialization rights with respect to a non-Affiliated Sublicensee, provided that (i) such Sublicensee is not then (a) in material breach of any provision of this CCPS Agreement or (b) in material breach of the applicable sublicense agreement or otherwise in breach of such sublicense agreement in a manner that would give rise to a right of termination on the part of Celgene, (ii) if Bluebird terminates this CCPS Agreement pursuant to Section 17.2(a) for Celgene’s failure to fulfill its payment obligations hereunder, such Sublicensee agrees to and does pay to Bluebird all outstanding amounts that accrued as a result of such Sublicensee’s activities under the

sublicense, (iii) Bluebird will have the right to step into the role of Celgene as sublicensor under any such sublicense executed after the CCPS Agreement Effective Date, with all the rights that Celgene had under such sublicense, solely with respect to the Bluebird Licensed IP, prior to termination of this CCPS Agreement (including the right to receive any payments to Celgene by such Sublicensee that accrue from and after the date of the termination of this CCPS Agreement solely with respect to the Bluebird Licensed IP), (iv) such Sublicensee will pay to Bluebird all amounts that Celgene would have been obligated to pay to Bluebird hereunder with respect to such Sublicensee’s activities had this CCPS Agreement not terminated (less any amounts received by Bluebird in clause (iii) above) and (v) the survival of such sublicense will not result in an imposition of any additional obligations on the part of Bluebird that are not included within the scope of this CCPS Agreement. Celgene will include in any sublicense agreement executed after the CCPS Agreement Effective Date that relates solely to the Bluebird Licensed IP a provision in which said Sublicensee acknowledges its obligations to Bluebird under this Section 17.4(b).

(c)Cessation of Rights. Except as otherwise expressly provided in this Section 17, all rights and licenses granted by Bluebird to Celgene in Section 10.1 will terminate, and all rights granted by Celgene to Bluebird in Section 10.2 will terminate, and Celgene and its Affiliates and Sublicensees will cease all use of Bluebird Licensed IP and all Development and Commercialization of Elected Candidate and Licensed Product.

(d)Regulatory Approvals. To the extent permitted by applicable Law, and subject to Bluebird paying commercially reasonable compensation to Celgene for the assets to be transferred pursuant to this Section 17.4(d) (such compensation to either be mutually agreed to or determined through arbitration as provided in Section 17.4(g) below, and such compensation to be reduced by [***] from what would be commercially reasonable compensation if this CCPS Agreement is terminated by Bluebird pursuant to Section 17.2(a)), all Regulatory Approvals and other regulatory filings and communications owned (in whole or in part) or otherwise Controlled by Celgene and its Affiliates and Sublicensees solely relating to the Elected Candidate and/or Licensed Product, and all other documents solely relating to and necessary to further Develop and Commercialize Elected Candidate and Licensed Product, as such items exist as of the effective date of such termination (including all solely related completed and ongoing clinical studies) will be assigned to Bluebird, and Celgene will provide to Bluebird one (1) copy of the foregoing and all documents contained in or referenced in any such items, together with the raw and summarized data for any clinical studies (and where reasonably available, electronic copies thereof). In the event of failure to obtain assignment, subject to the Parties agreeing on commercially reasonable compensation for the right to access and reference, Celgene hereby consents and grants to Bluebird the right to access and reference (without any further action required on the part of Celgene, whose authorization to file this consent with any Regulatory Authority is hereby granted) any such item.

(e)Licenses. Subject to Bluebird paying (i) commercially reasonable compensation to Celgene for the licenses to be granted pursuant to subsection (1) of this Section 17.4(e) (such compensation to either be mutually agreed to or determined through arbitration as provided in Section 17.4(g) below, and such compensation to be reduced by [***] from what would be

commercially reasonable compensation if this CCPS Agreement is terminated by Bluebird pursuant to Section 17.2(a)), and (ii) amounts payable to Celgene’s licensors as set forth below, Celgene will grant to Bluebird and its Affiliates (1) a worldwide, perpetual and irrevocable, nontransferable (except in connection with a permitted assignment of this CCPS Agreement in accordance with Section 18.12), exclusive license, with the right to grant sublicenses through multiple tiers (subject to Section 10.3, mutatis mutandis), under Celgene Licensed Product IP, and (2) an exclusive sublicense under the Celgene Licensed Product In-Licensed IP, in each case ((1) and (2)) to the extent such Celgene Licensed Product IP and Celgene Licensed Product In-Licensed IP are used in or Cover the Licensed Product as of the effective date of termination and to the extent such Celgene Licensed Product IP and Celgene Licensed Product In-Licensed IP exist as of the effective date of such termination (including in each case any additions, divisions, continuations, continuations-in-part, invention certificates, substitutions, reissues, reexaminations, extensions, registrations, supplementary protection certificates and renewals of such Celgene Licensed Product IP and Celgene Licensed Product In-Licensed IP), solely to the extent necessary to research, Develop, Manufacture and Commercialize the Elected Candidate and Licensed Product. With respect to grants of a sublicense under subsection (2) above, Bluebird will be responsible for all amounts payable to the applicable licensor, excluding maintenance fee payments, payments that are triggered by the grant of a sublicense (but including payments triggered by further grants of sublicenses by Bluebird or its sublicensees) and Patent Costs, that are attributable to Bluebird as a sublicensee thereunder under this CCPS Agreement, and Celgene will pay same and Bluebird will reimburse Celgene for [***] percent ([***]%) of such payments within thirty (30) days of receipt of Celgene’s written invoice therefor. Celgene will provide Bluebird with copies of all applicable Celgene Licensed Product In-Licenses promptly following the effective date of the termination of this License Agreement. The Prosecution and Maintenance and enforcement and defense rights and obligations of the Parties with respect to any Patents licensed or sublicensed to Bluebird pursuant to this Section 17.4(e) will be discussed and agreed to by the Parties, with the understanding that such Prosecution and Maintenance and enforcement and defense rights and obligations will be substantially similar to those set forth in Section 13, with the roles of Bluebird and Celgene reversed (and such other changes as are appropriate from the context, and taking into account any rights retained by a Third Party licensor of Celgene to Prosecute and Maintain or enforce and defend any Patent sublicensed to Bluebird under this Section 17.4(e)).

(f)Trademarks. Subject to Bluebird paying commercially reasonable compensation to Celgene for the license to be granted pursuant to this Section 17.4(f) (such compensation to either be mutually agreed to or determined through arbitration as provided in Section 17.4(g) below, and such compensation to be reduced by [***] from what would be commercially reasonable compensation if this CCPS Agreement is terminated by Bluebird pursuant to Section 17.2(a)), Celgene will exclusively license to Bluebird any registered or unregistered trademarks or internet domain names that are specific to and solely used for the Licensed Product worldwide (it being understood that the foregoing will not include any trademarks or internet domain names that contain the corporate or business name(s) of Celgene).

(g)Commercially Reasonable Compensation. If the Parties are unable to agree on the amount of commercially reasonable compensation payable by Bluebird to Celgene pursuant to Sections 17.4(d), 17.4(e) or 17.4(f) within ten (10) days of the effective date of termination of this CCPS Agreement, [***].

(h)Country Termination. If this CCPS Agreement is terminated only with respect to a specific country pursuant to Section 11.2(b) or Section 11.3(c), the provisions of this Section 17.4 will apply only with respect to such terminated country.

17.5 Survival. In addition to the termination consequences set forth in Section 17.4, the following provisions will survive termination or expiration of this CCPS Agreement: Sections 1, 4.3, 8.2, 8.3(b), 10.3(c) (mutatis mutandis with respect to licenses granted to Bluebird under Section 17.4, but excluding subsections (i) and (ii) of Section 10.3(c)), 10.6, 10.8, 11.5, 11.6, 12, 15, 16.3, 16.4, 16.6, 16.7, 16.8, 17.4, 17.5, 17.6 and 18, and Appendix F (to the extent required to provide for a true up of Operating Profit or Losses during the term of this CCPS Agreement following termination of this CCPS Agreement). Termination or expiration of this CCPS Agreement will not relieve the Parties of any liability or obligation which accrued hereunder prior to the effective date of such termination or expiration nor preclude either Party from pursuing all rights and remedies it may have hereunder or at law or in equity with respect to any breach of this CCPS Agreement nor prejudice either Party’s right to obtain performance of any obligation. All other rights and obligations will terminate upon expiration of this CCPS Agreement.

17.6 Right to Set-off.

18.15 Severability. In the event that any provision of this CCPS Agreement will, for any reason, be held to be invalid or unenforceable in any respect, such invalidity or unenforceability will not affect any other provision hereof, and the Parties will negotiate in good faith to modify this CCPS Agreement to preserve (to the extent possible) their original intent.
