“This Section 11.5 will apply solely as it relates to Celgene’s payment obligations under Section 11.1, and the reporting obligations related thereto and solely as needed for Bluebird to comply with its obligations under the Bluebird Applicable In-Licenses.”

1.22 Section 11.6 of the CCPS Agreement is hereby amended by deleting the existing text and replacing it with the following text:

“11.6 [Reserved].”

1.23 Section 14.2(e)(ii)(A) of the CCPS Agreement is hereby amended by deleting the existing text and replacing it with the following text:

“(A) To the extent such recovery reflects lost profits damages, if Celgene was the controlling Party or the Parties jointly controlled, Celgene will retain such lost profits recovery, and if Bluebird was the controlling Party, [***] to Bluebird and [***] to Celgene;”

1.24 Section 15 of the CCPS Agreement is hereby amended by deleting the existing text and replacing it with the following text:

“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 terms of which survive during the CCPS Agreement Term and for ten (10) years thereafter. Notwithstanding Section 8 of the Master Collaboration Agreement, data arising from Clinical Studies conducted under the CCPS Agreement relating to the Elected Candidate or Licensed Product (“Clinical Data”) shall be the Confidential Information of [***]. 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.”

1.25 Section 17.1 is hereby amended by deleting the existing text and replacing it with the following text:

“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 until Licensed Product is no longer being Developed or Commercialized in the United States. For all countries (other than the United States), the licenses to Celgene contained in Section 10.1 are perpetual and fully paid up (subject to reimbursement to Bluebird of any In-License Payments pursuant to Section 11.1) and will remain exclusive with respect to Licensed Product in all such countries.”

1.26 Section 17.2(c) of the CCPS Agreement is hereby amended by deleting existing text and replacing it with the following text:

(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, provided that such license agreement shall in no event require Celgene to pay any milestone payment or royalties in relation to the Development and Commercialization of Elected Candidate and Licensed Product for ROW Administration. 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 [***] period, 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 CCPS 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.
