 ARTICLE 10 

INDEMNIFICATION; INSURANCE 

10.1 Indemnification by Celgene. Celgene shall indemnify, defend and hold harmless Juno and its directors, officers, employees and
agents (collectively, the “Juno Indemnitees”), from and against any and all Damages to the extent arising out of or relating to, directly or indirectly, from any Claim based upon: 

10.1.1. the [***], in connection with [***] under this Agreement; 

10.1.2. any [***] under this Agreement; or 

10.1.3. the [***], including any [***] resulting from any of the foregoing [***]; 

in each case, provided however that, such indemnity shall not apply to the extent Juno has an indemnification obligation pursuant to Section 10.2 for
such Damages. 
 10.2 Indemnification by Juno. Juno shall indemnify, defend and hold harmless Celgene and its directors, officers,
employees and agents (collectively, the “Celgene Indemnitees”), from and against any and all Damages to the extent arising out of or relating to, directly or indirectly, from any Claim based upon: 

10.2.1. the [***] in connection with [***] under this Agreement; 

10.2.2. any [***] under this Agreement; or 

10.2.3. the [***], including any [***]resulting from any of the foregoing [***]; 

  
 [***] Certain information in this
document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 

  
 128 

 in each case, provided however that, such indemnity shall not apply to the extent Celgene has an indemnification
obligation pursuant to Section 10.1 for such Damages. 
 10.3 Notice of Claims. A Claim to which indemnification applies under
Section 10.1 or Section 10.2 shall be referred to herein as an “Indemnification Claim.” If the Indemnitee intends to claim indemnification under this Article 10, the Party claiming indemnification (the
“Indemnitee”) shall notify the indemnifying Party (the “Indemnitor”) in writing, promptly upon becoming aware of an Indemnification Claim, describing in reasonable detail the facts giving rise to the Indemnification
Claim; provided, that an Indemnification Claim in respect of any action at law or suit in equity by or against a Third Party as to which indemnification shall be sought shall be given promptly after the action or suit is commenced (provided that the
Indemnitee is aware of such commencement); and provided further, that the failure by an Indemnitee to give such notice shall not relieve the Indemnitor of its indemnification obligation under this Agreement except and only to the extent that the
Indemnitor is actually prejudiced as a result of such failure to give notice. 
 10.4 Indemnification Procedures. If an Indemnitee
receives written notice of a Claim that the Indemnitee believes may result in a claim for indemnification under this Article 10, such Indemnitee shall deliver an Indemnification Claim to the Indemnitor in accordance with the provisions of
Section 10.3. If [***], then the Indemnitor shall have the right to assume and control the defense of the Claim, at its own expense with counsel selected by it and reasonably acceptable to the Indemnitee, by delivering written notice of its
assumption of such defense to the Indemnitee within [***] of its receipt of notice of such Claim from the Indemnitor (but the Indemnitor shall in any event have the right to assume and control the defense of a Claim that [***], whichever is first);
provided, however, that the Indemnitee shall have the right to retain its own counsel, with the reasonable fees and expenses to be paid by the Indemnitor, if (a) representation of the Indemnitee by the counsel retained by the Indemnitor would
be inappropriate due to actual or potential conflict of interests between such Indemnitee and Indemnitor, (b) the Indemnitor has failed within a reasonable time to retain counsel, (c) the Indemnitee shall have reasonably concluded that
there may be legal defenses available to it that are different from or in addition to those available to the Indemnitor, or (d) [***]. If the Indemnitor assumes and controls the defense of such Claim, the Indemnitor shall keep the Indemnitee
reasonably apprised of the status of the Claim and the Indemnitee shall be entitled to otherwise monitor such Claim at its sole cost and expense. If the Claim [***] against or from the Indemnitee or if the Indemnitor does not assume the defense of
the Claim as described in this Section 10.4, the Indemnitee shall be permitted to assume and control the defense of such Claim (but shall have no obligation to do so) and in such event shall be entitled to settle or compromise the
Indemnification Claims in its sole and reasonable discretion, provided that if the Indemnitee is entitled to assume the defense of the Claim pursuant to this Section 10.4 solely because the Claim [***] against or from the Indemnitee, then the
Indemnitee shall not settle or compromise such Indemnification Claims in any manner that [***] 

  
 [***] Certain information in this
document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 

  
 129 

 
[***] without the prior written consent of the Indemnitor, which consent the Indemnitor shall not unreasonably withhold, condition or delay. If the Indemnitor has assumed and controls the defense
of the Claim in accordance with this Section 10.4, (i) the Indemnitee shall not settle or compromise the Indemnification Claim without the prior written consent of the Indemnitor, such consent not to be unreasonably withheld, conditioned
or delayed and (ii) the Indemnitor shall not settle or compromise the Indemnification Claim in any manner that would result in the payment of amounts by the Indemnitee, impose any other obligation on the Indemnitee or otherwise have an adverse
effect on the Indemnitee’s rights or interests (including any rights under this Agreement or the Equity Purchase Agreement or the scope or enforceability of any Patents or Know-How licensed by one Party to another Party pursuant to this
Agreement or a Development & Commercialization Agreement), without the prior written consent of the Indemnitee. In each case, the Party that is not controlling the defense of any Claim shall reasonably cooperate with the Party that is
controlling the defense of such Claim, at the non-controlling Party’s expense and shall make available to the controlling Party all pertinent information under the control of the non-controlling Party, which information shall be subject to
Article 8 (Confidentiality). Each Party shall use commercially reasonable efforts to avoid production of Confidential Information of the other Party (consistent with applicable Law and rules of procedure), and to cause all communications among
employees, counsel and other representatives of such Party to be made so as to preserve any applicable attorney-client or work-product privileges. 

10.5 Indemnification Following Exercise of the Option. The Development & Commercialization Agreements provide separately for
each Party’s indemnification obligations with respect to each Development Candidate, Product or Diagnostic Product, that is the subject of such agreement following exercise of the Option for such Program. 

10.6 LIMITATION OF LIABILITY. EXCEPT (A) FOR A BREACH OF SECTIONS [***]. AS APPLICABLE, OR [***] OR (B) FOR CLAIMS THAT ARE
SUBJECT TO INDEMNIFICATION UNDER THIS Article 10 OR (C) FOR DAMAGES DUE TO THE [***] OF THE LIABLE PARTY, NEITHER JUNO NOR CELGENE, NOR ANY OF THEIR RESPECTIVE AFFILIATES WILL BE LIABLE TO THE OTHER PARTY TO THIS AGREEMENT OR ITS AFFILIATES FOR
ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR PUNITIVE OR EXEMPLARY DAMAGES OR LOST PROFITS OR LOST DATA, WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY OR CONTRIBUTION, AND
IRRESPECTIVE OF WHETHER THAT PARTY OR ANY REPRESENTATIVE OF THAT PARTY HAS BEEN ADVISED OF, OR OTHERWISE MIGHT HAVE ANTICIPATED THE POSSIBILITY OF, ANY SUCH LOSS OR DAMAGE.

 ARTICLE 11 

TERM AND TERMINATION 

11.1 Term; Expiration. Unless earlier terminated in accordance with this Article 11, the term of this Agreement (the
“Term”) shall commence as of the Effective Date and remain in force until the later of (a) the expiration of the last-to-expire of all Option Terms and (b) if one or more Options is exercised, the termination or expiration
of the last to expire Development & Commercialization Agreement executed with respect to any Program hereunder. 
 11.2
Termination for Breach. 
 11.2.1. Material Breach. Subject to the other terms of this Agreement, this Agreement and the rights
granted herein may be terminated by either Party (a) on a Program-by-Program basis prior to the exercise of an Option or BD Option for such Program, as applicable, for the material breach by the other Party of this Agreement with respect to
such Program that frustrates the fundamental purpose of this Agreement, or (b) on a Program-by-Program basis after a Party’s exercise of an Option or BD Option for such Program, if a Development & Commercialization Agreement for
such Program is terminated for material breach by a Party that frustrates the fundamental purpose of this Agreement; provided in each of (a) or (b), that the breaching Party has not cured such breach within [***] after the date of written
notice to the breaching Party of such breach (or [***] in the case of a breach as a result of non-payment of any amounts due under this Agreement or a Development & Commercialization Agreement, as applicable) (the “Cure
Period”), which notice shall describe such breach in reasonable detail and shall state the non-breaching Party’s intention to terminate this Agreement with respect to a given Program, pursuant to this Section 11.2.1 with respect
to such Program. For clarity, the Cure Period for any allegation made in good faith as to a material breach under this Agreement with respect to a given Program for events described in this Section 11.2.1 will run from the date that written
notice was first provided to the breaching Party by the non-breaching Party. Any such termination of this Agreement with respect to a given Program under this Section 11.2.1 shall become effective at the end of the Cure Period, unless the
breaching Party has cured any such breach or default prior to the expiration of such Cure Period, or, if such breach is not susceptible to cure within the Cure Period, then, the non-breaching Party’s right of termination shall be [***]. For the
avoidance of doubt, termination of any particular Program(s) pursuant to this Section 11.2.1 shall not terminate (i) this Agreement with respect to any other Program(s), or (ii) any Development & Commercialization Agreement
for any other Program. The Parties understand and agree that the totality of this Agreement with respect to a given Program, and the [***]. 

11.2.2. Disagreement as to Material Breach. If the Parties reasonably and in good faith disagree as to whether there has been a
material breach pursuant to Section 11.2.1, subject

 131 

 
to Section 12.7, the Party that disputes that there has been a material breach may contest the allegation by referring such matter, within [***] for resolution to the Executive Officers, who
shall meet promptly to discuss the matter, and determine, within [***] following referral of such matter, whether or not a material breach has occurred pursuant to Section 11.2.1, as applicable. If the Executive Officers are unable to resolve a
dispute within such [***] period after it is referred to them, the matter will be resolved as provided in Section 12.7. It is understood and agreed that (a) during the pendency of any such dispute, all of the terms and conditions of this
Agreement shall remain in effect and the Parties shall continue to perform all of their respective obligations hereunder), and (b) if it is finally and conclusively determined that the breaching Party committed such material breach, then the
breaching Party shall have the right to cure such material breach after such determination within the Cure Period provided above, less [***]. 

11.3 Voluntary Termination. 

11.3.1. Termination by Celgene. Celgene may terminate this Agreement in its entirety (but, for clarity, not on Program by Program
basis) at will, subject to Section 11.3.2, at any time during the Term upon [***] prior written notice to the other Party hereunder. 

11.3.2. Restrictions. For clarity, neither Party may terminate this Agreement pursuant to this Section 11.3 with respect to any
Program for which such Party has exercised its Option during the term of any applicable Development & Commercialization Agreement for such Program, unless it also terminates such Development & Commercialization Agreement. 

11.4 Termination for Bankruptcy. If either Party makes a general assignment for the benefit of creditors, appoints or suffers
appointment of a receiver or trustee over all or substantially all of its property, files a petition under any bankruptcy or insolvency act or has any such petition filed against it which is not dismissed, discharged, bonded or stayed within ninety
(90) days after the filing thereof, the other Party may terminate this Agreement in its entirety effective immediately upon written notice to such Party, provided that this Agreement may only be terminated in its entirety pursuant to this
Section 11.4 in connection with the termination of all Development & Commercialization Agreements (if any), executed hereunder. In connection therewith, the provisions of Section 7.1.7 shall apply. 

11.5 Termination for Patent Challenge. Either Party shall have the right to terminate this Agreement solely on a Program-by-Program
basis upon written notice if the other Party or any Affiliate (as defined in Section 1.2(a)) challenges the validity, scope or enforceability of or otherwise opposes any Patent (a) included in the [***] and that is licensed to Celgene
under this Agreement, or (b) included in the [***] and that is licensed to Juno under this Agreement (other than in either case as may be necessary or reasonably required to assert a cross-claim or a counter-claim or to respond to a court
request or order or administrative law, request or order) it being understood and agreed that either Party’s right to terminate this Agreement under this Section 11.5 shall not apply to any

  
 [***] Certain information in this
document has been omitted and filed separately with the Securities and Exchange Commission. Confidential treatment has been requested with respect to the omitted portions. 

  
 132 

 
actions undertaken by an Affiliate (as defined in Section 1.2(a)) of the other Party (the “Challenging Party”) that first becomes such an Affiliate as a result of or after
the effective date of a Business Combination involving the Challenging Party, where such new Affiliate was undertaking any of the activities described in the foregoing clause prior to such Business Combination; provided that a Party’s right to
terminate this Agreement under this Section 11.5 shall apply to actions undertaken by such new Affiliate if the Challenging Party is the acquiror in such Business Combination and such new Affiliate does not terminate or otherwise cease such
challenge or opposition within [***] after the effective date of such Business Combination. If a Sublicensee of a Party challenges the validity, scope or enforceability of or otherwise opposes any Patent (i) included in the [***] (in the case
of a Sublicensee of Celgene), or (ii) included in the [***] (in the case of a Sublicensee of Juno), in each case under which such Sublicensee is sublicensed, then such Party shall, [***], terminate such sublicense. For the avoidance of doubt,
an action by a Party or any Affiliate (as defined in Section 1.2(a)) (collectively the “Prosecuting Party”) in accordance with Article 7 to amend claims within a pending patent application of the other Party during the course
of the Prosecuting Party’s Prosecution and Maintenance of such pending patent application or in defense of a Third Party proceeding, or to make a negative determination of patentability of claims of a patent application of the other Party or to
abandon a patent application of the other Party during the course of the Prosecuting Party’s Prosecution and Maintenance of such pending patent application, shall not constitute a challenge under this Section 11.5. 

11.6 Termination for Failure to Close Share Purchase Agreement or Breach of Standstill. Juno may terminate this Agreement immediately
upon written notice to Celgene, in the event that (i) either Juno or Celgene terminates the Equity Purchase Agreement pursuant to Section 6.1 thereof prior to the first acquisition of shares of capital stock of Juno pursuant to
Section 2.1 of the Equity Purchase Agreement, other than by reason of a Terminating Company Breach (as defined therein), or (ii) Juno exercises its right to terminate this Agreement under Section 2.2 of the Voting and Standstill
Agreement dated as of the Original Execution Date (“Voting and Standstill Agreement”), by and between Juno and Celgene resulting in the termination of the Voting and Standstill Agreement.

Severability. If any one or more of the terms or provisions of this Agreement is held by a court of competent jurisdiction or arbitrator to be void, invalid or unenforceable in any situation in any jurisdiction, such holding shall not affect the
validity or enforceability of the remaining terms and provisions hereof or the validity or enforceability of the invalid, void or unenforceable term or provision in any other situation or in any other jurisdiction and the term or provision shall be
considered severed from this Agreement, unless the invalid or unenforceable term or provision is of such essential importance to this Agreement that it is to be reasonably assumed that the Parties would not have entered into this Agreement without
the invalid or unenforceable term or provision. If the final judgment of such court or arbitrator declares that any term or provision hereof is invalid, void or unenforceable, the Parties agree to (a) reduce the scope, duration, area or
applicability of the term or provision or to delete specific words or phrases to the minimum extent necessary to cause such term or provision as so reduced or amended to be enforceable, and (b) make a good faith effort to replace any invalid or
unenforceable term or provision with a valid and enforceable one such that the objectives contemplated by the Parties when entering this Agreement may be realized.

Arbitration Issue that, to the extent possible, reflects the terms and conditions of this Agreement, the Expert’s views as to how each Arbitration Issue should be resolved in the global pharmaceutical industry between two (2) independent

authority to assume or create any obligations on behalf of or in the name of Celgene or Juno, respectively, or to bind Celgene or Juno, respectively, to any contract, agreement, or undertaking with any Third Party. There are no express or implied

manner and respects as an original executed counterpart and shall be considered to have the same binding legal effect as if it were the original signed version thereof delivered in person. No Party hereto shall raise the use of Electronic Delivery
to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of Electronic Delivery as a claim or defense with respect to the formation of a contract, and each Party forever waives
any such claim or defense, except to the extent that such claim or defense relates to lack of authenticity. 
 12.12 Equitable
Relief. Notwithstanding anything to the contrary herein, the Parties shall be entitled to seek equitable relief, including injunction and specific performance, as a remedy for any breach of this Agreement. Such remedies shall not be deemed to be

breach of this Agreement is or would be compensable by an award of money damages.

similar subject matters may be addressed in different provisions of this Agreement, the Parties intend that, except as reasonably apparent on the face of the Agreement or as expressly provided in this Agreement, each such provision shall be read

determinable [***], the JCC will develop a reasonable methodology for determining such costs. Reasonable methodologies may include a standard rate or some other appropriate basis for allocating costs.

Section 6.5.1 or receipt of written notice from a Third Party that reasonably evidences Celgene Program Co-Co Competitive Infringement, to elect to so enforce such Celgene Program Co-Co Product Patent in the applicable jurisdiction (or to
settle or otherwise secure the abatement of such Celgene Program Co-Co Competitive Infringement), provided however, that such period will be (a) more than [***] to the extent applicable Law prevents earlier enforcement of such Celgene Program
Co-Co Product Patent (such as the enforcement process set forth in or under the Hatch-Waxman Act or Public Health Service Act, or any ex-U.S. equivalent of the either of the foregoing)), and provided further that if such period is extended because
applicable Law prevents earlier enforcement, the enforcing Party shall have until the date that is [***] following the date upon which applicable Law first permits such Celgene Program Co-Co Enforcement Proceeding, and (b) less than [***] to
the extent that a delay in bringing such Celgene Program Co-Co Enforcement Proceeding against such alleged Third Party infringer would limit or compromise the remedies (including monetary relief, and stay of regulatory approval) available against
such alleged Third Party infringer. In the event Celgene [***] before the first to occur of (i) the expiration of the applicable period of time set forth in the preceding subsections (a) and (b), or (ii) [***] before the expiration of
any time period under applicable Law, that would, if a Celgene Program Co-Co Enforcement Proceeding was not filed within such time period, limit or compromise the remedies available from such Celgene Program Co-Co Enforcement Proceeding, it will
[***] and in the case where Juno then [***] the applicable Celgene Program Co-Co Product Patent with respect to such Celgene Program Co-Co Competitive Infringement in the applicable jurisdiction, Juno will thereafter have[***] to enforce the
applicable Celgene Program Co-Co Product Patent (such action, a “Celgene Program Co-Co Step-In Proceeding”) at Juno’s expense.

Celgene Program Co-Co Step-In Proceeding, at the enforcing Party’s written request, (subject to Section 6.5.8), the other Party will join any such action or proceeding as a party and will use Commercially Reasonable Efforts to cause any
Third Party as necessary to join such action or proceeding as a party if doing so is necessary for the purposes of establishing standing or is otherwise required by applicable Law to pursue such action or proceeding. All time periods set forth in
Section 6.5.3 shall be subject to applicable Law, which may prevent earlier enforcement.

then shall be applied to reimburse all out-of-pocket costs and expenses incurred by each Party directly in connection with such action (including, for this purpose, [***]), and if such recovery is insufficient to cover all such costs and expenses of
both Parties, it shall be [***]; and
