“Parties”. 
 WHEREAS, LLS is a national voluntary health agency which, among other activities, encourages and sponsors
research relating to leukemia, lymphoma, Hodgkin’s disease and myeloma (the “Disease”) to develop therapies to cure or mitigate the Disease, and engages in other charitable and educational activities to increase understanding
and public awareness of the Disease. To further this mission, LLS provides research funding to entities that can demonstrate after LLS’s review process that their proposed research projects have scientific promise to advance LLS’s effort
to find treatments and cures for the Disease and its complications.

of written notice from LLS to Company of the occurrence of a Default to cure such Default): 
 (a)    Any material
violation by Company of any applicable law in the conduct of the Research Program; 
 (b)    Any material breach or
default by Company in the performance of any of its covenants or obligations hereunder (other than any Interruption, which shall be governed by Section 12.6 and not this Section 12.5); 

(c)    Any representation or warranty made by Company in this Agreement that is not true in any material respects; and/or


  
 29

12.6    Interruption. 

(a)    LLS shall notify Company in writing if it believes an Interruption has occurred (the “Interruption
Notice”). If Company disputes the Interruption Notice, it shall respond in writing within [**] of receipt of the Interruption Notice providing specific evidence supporting its response. If LLS disagrees with such response, such dispute
shall be resolved in accordance with Section 11 of this Agreement. 
 (b)    If Company agrees with the

remedy and Company’s sole and exclusive liability with respect to such Interruption: (i) to receive repayment of the Funding (less any amount previously paid to LLS under Section 9.3) (the “LLS Repayment
Election”), in which event the Interruption License shall terminate; or (ii) to exercise the Interruption License, subject to Section 12.6(c). 

(c)    If LLS elects the Interruption License pursuant to Section 12.6(b)(ii), then Company shall have the right,
exercisable in writing to LLS within [**] after receipt of the Interruption Election Notice, to elect to pay to LLS [**] times the Funding (less any amount previously paid to LLS under Section 9.3) (the “Company Repayment
Election”), in which event the Interruption License shall not be exercisable by LLS and shall terminate. 

(d)    If Company does not make the Company Repayment Election pursuant to Section 12.6(c), LLS shall be entitled to
exercise the Interruption License, and this Agreement shall terminate, as set forth in Section 12.7(d). 

(e)    If either Party exercises the Repayment Election, LLS shall retain its rights to payments from Company pursuant to
Section 9.3, which shall be calculated based on the Funding paid to Company prior to the exercise of the Repayment Election.

(a)    All Terminations. Upon termination of this Agreement, each Party shall return to the other Party, upon the
other Party’s request, all tangible items of the other Party in its possession or under its control evidencing the Confidential Information of the other Party; provided, that neither Party shall be required to return or destroy
automatically created copies of the other Party’s Confidential Information stored on system back-up media. The termination of this Agreement will not affect any rights or claims of a Party hereunder that
accrued prior to the date of such termination (except pursuant to Section 12.8(b)). 
 (b)    Termination by LLS
Pursuant to Section 5.2 or 12.5. Upon termination of this Agreement by LLS pursuant to Section 5.2 or 12.5, Company shall within [**] after the date of termination pay to LLS an amount equal to [**] times the amount of
the Funding. In addition, if Company continues development of a Product after such termination, Company shall pay LLS the payments specified in Section 9.3, subject to the Payment Cap. 

(c)    Termination by Company Pursuant to Section 12.4. Upon termination of this Agreement by
Company pursuant to Section 12.4, LLS shall compensate Company for the work Company has completed up to the date of termination by paying Company the balance of any funds owed for each completed Milestone and a pro rata portion of the
amount due for any partially completed Milestone prior to the receipt of notice of termination after receiving documentation from the Company documenting any partially completed work. However, such payment, together with all other payments made by
Company to LLS pursuant to this Agreement, shall not exceed the maximum Funding provided for in Section 2.1 of this Agreement. [**]. 

(d)    Termination Due to Interruption. If this Agreement terminates pursuant to Section 12.6(d) and neither
Party makes the Repayment Election: 
 (i)    LLS shall be entitled to exercise the Interruption License; and 

(ii)    Company shall, upon LLS’s reasonable request, provide LLS, at no charge, with access to the Research Program
Inventions and Research Program Results, data, and, to the extent not integral to another product or product candidate of Company, all other materials that Company Controls necessary to practice the Interruption License; and 

(iii)    Section 9.5 shall survive termination. 

  
 31 








 12.8    Survival; Release. 

(a)    The following provisions shall survive the termination of this Agreement: 5.3, 7, 8 (other than 8.6), 9.3 (only in
the event of a termination under Section 12.5), 9.4 (only in the event of a termination under Section 12.5), 10, 11, 12.7, 12.8, 13, 14.2, 14.3, 14.4, 14.5, 14.6, 14.8, 14.9 and 14.10. 

(b)    Notwithstanding anything to the contrary herein, including Section 12.8(a) above, if a Change of Control
Transaction occurs pursuant to an exercise of the Genentech Option concurrently with or following the termination of this Agreement, then: 

(i)    all surviving obligations of Company under this Agreement, including without limitation those provisions set forth
in Section 12.8(a) above, and any dispute, arbitration or litigation then existing between the Parties, shall be deemed to have terminated automatically effective immediately prior to the close of such Change of Control Transaction; 

(ii)    effective immediately prior to the close of a Change of Control Transaction pursuant to the exercise of the
Genentech Option, LLS, on behalf of the Indemnitees, hereby irrevocably releases Company, its Affiliates, their respective directors, officers, representatives, employees and agents, and their respective successors, heirs and assigns from any and
all liabilities that may have arisen under this Agreement prior to such Change of Control Transaction. 
  

	13.	Indemnification. 

 13.1    Indemnification. Company
agrees to indemnify, hold harmless and defend, LLS and LLS’s directors, officers, representatives, employees and agents and their respective successors, heirs and assigns (each an “Indemnitee”) from and against any and all
claims, losses, expenses, demands, suits, liability or damage for personal injury, property damage or otherwise, including reasonable attorneys’ fees, incurred in connection with any Third Party suit (collectively “Claims”), to
the extent arising directly or indirectly from, relating to, or resulting from (a) any research performed under this Agreement, including research undertaken by one or more investigators or subcontractors pursuant to one or more agreements
between Company and its subcontractors and investigators, (b) any Product developed in whole or in part from such research, (c) any claim that Company’s conduct of the Research Program infringes or misappropriates intellectual
property of any Third Party, (d) any material breach of Company’s representations, warranties, covenants or obligations under this Agreement, and (e) the conduct of Company’s business or operations outside of the Research
Program. 

  
 32 








 Notwithstanding the foregoing, Company shall have no obligations pursuant to this Agreement to
defend or indemnify LLS from any Claim to the extent it arises from (w) LLS’s negligence or willful misconduct, (x) any material breach by LLS of its representations, warranties, covenants or obligations under this Agreement,
(y) the conduct by LLS of its business or operations outside of the Research Program, or (z) any activities conducted by LLS or its Affiliates or licensees under the Interruption License. 

13.2    Indemnification Procedures. 

(a)    In the case of any Claim asserted against an Indemnitee, such Indemnitee shall (i) notify Company in writing
as soon as it becomes aware of any Claim and shall permit Company (at the expense of Company) to assume defense or settlement of any Claim and (ii) cooperate fully with the legal representative chosen by Company, who shall be reasonably
satisfactory to Indemnitee, provided that the failure of any Indemnitee to give notice as provided herein shall not relieve Company of its indemnification obligation hereunder except to the extent that such failure results in a lack of
actual notice to Company and Company is materially prejudiced as a result of such failure to give notice. 

(b)    Except with the prior written consent of the Indemnitee, such consent not to be unreasonably withheld, conditioned
or delayed, Company shall not consent to entry of any judgment or enter into any settlement that provides for injunctive or other non-monetary relief affecting the Indemnitee or that does not include as an
unconditional term thereof the giving by each claimant or plaintiff to such Indemnitee of a release from all liability with respect to such Claim. 

13.3    Insurance. Company shall obtain and maintain during the term of this Agreement liability,
comprehensive, and workers’ compensation insurance with a reputable insurance company to protect against those insurable risks that Company may incur in connection with the performance of its obligations under this Agreement. Company will
provide, upon request, evidence of any such policies of insurance. 

  
 33 








 13.4    Limitation on Liability. EXCEPT FOR COMPANY’S OBLIGATIONS
TO INDEMNIFY A THIRD PARTY PURSUANT TO SECTION 13.1, IT IS AGREED BY THE PARTIES THAT NEITHER PARTY SHALL BE LIABLE FOR ANY SPECIAL, INDIRECT, EXEMPLARY, PUNITIVE OR CONSEQUENTIAL DAMAGES, INCLUDING LOST PROFITS, ARISING OUT OF THIS AGREEMENT OR ITS
SUBJECT MATTER, EVEN IF A PARTY HAS BEEN ADVISED OF THE POSSIBILITY OF SUCH DAMAGES. IN ADDITION, THE AGGREGATE AMOUNT OF COMPANY’S ENTIRE LIABILITY HEREUNDER, INCLUDING, WITHOUT LIMITATION FOR ALL PAYMENT OBLIGATIONS UNDER SECTIONS 9, 12 AND
13.1, SHALL IN NO EVENT EXCEED THE PAYMENT CAP. 
  

	14.	Miscellaneous Provisions. 

 14.1    Relationship of
Parties. The Parties do not intend this Agreement to create a legal partnership, joint venture, or agency relationship. There are no third party beneficiaries to this Agreement. The activities and resources of each Party shall be managed by such

obligations on behalf or in the name of the other Party or to bind the other Party to any contract, agreement or undertaking with any third party.

relating to its subject matter (including the Company Proposal and the Confidentiality Agreement). Any amendment, alteration or modification must be in writing and signed by the Parties. Any waiver of any rights or failure to act in a specific

this Agreement.

 14.8    Severability. If any provision of this Agreement is
inoperative or unenforceable for any reason in any jurisdiction, such circumstances shall not have the effect of rendering the provision in question inoperative or unenforceable in any other case, circumstance or jurisdiction, or of rendering any

is hereby added to the Agreement to read as follows: 
 “1.53 “BET Compound” shall mean any Company proprietary,
internally developed compound that (a) is targeted to any one (or more) of the following [**] tandem bromodomain-containing proteins, including but not limited to wildtype proteins, any engineered or disease associated mutants, any
polymorphisms, any splice variants and any translocations: [**] and (b) is designed for, and is being researched for, use in the Field.” 

5.    Section 1.54 is hereby added to the Agreement to read as follows: 

“1.54 “First Amendment Date” shall mean April 9, 2013. 

6.    Section 2.11 is hereby added to the Agreement to read as follows: 

“2.11 Go Decisions. 

(a)    To the extent permitted under its agreements with Third Parties as of the Effective Date, Company shall, during the
term of this Agreement until [**], propose to LLS for potential funding by LLS each BET Compound with respect to which Company completes GLP toxicity testing in accordance with die remaining provisions of this Section 2.11, which, for clarity,
may include [**]. 
 (b)    LLS shall have [**] (the “Diligence Period”) from the date on which Company
provides LLS with a draft GLP toxicity report for a BET Compound to decide whether LLS wishes to provide funding for the research and possible development of such BET Compound by notifying Constellation of such decision (such decision, if positive
and provided to Company during the Diligence Period, a “Go Decision”). During the applicable Diligence Period, Constellation shall furnish such additional information that LLS reasonably requests regarding the applicable BET
Compound to the extent LLS requires such information to determine whether to make the Go Decision. 
 (c)    LLS shall
not be required to provide funding for the preclinical development of any BET Compound unless LLS makes a Go Decision with respect to such BET Compound. For clarity, from and after the First Amendment Date, unless and until LLS makes a Go Decision
with respect to [**], (i) LLS shall not be required to provide any further funding for [**] and (ii) Company shall have no research or development obligations under this Agreement, and LLS shall have no right to provide an Interruption Notice,
with respect to [**]. 







 (d)    The first BET Compound, if any, for which LLS makes a Go Decision
within the applicable Diligence Period shall become the Compound under this Agreement, at which time LLS shall provide Funding for such BET Compound, the amount of which Funding shall be subject to any applicable cap and shall take into account
Funding amounts previously paid for [**]. Promptly following such Go Decision, Company and LLS shall diligently negotiate in good faith revised dates specified in Exhibit A, revised Projected Dates specified in Exhibit C and revised RAC meeting
dates in Exhibit E, following which Company and LLS shall so amend such Exhibits, all references to “[**]” in Exhibits A and C shall be amended to refer to such BET Compound, and the Research Program shall proceed in accordance with
Exhibits A, C and E as so amended. If the Parties, despite diligent good faith efforts, have not so amended Exhibit A, C and E within [**] after such Go Decision, neither Party shall have any obligation to the other Party with respect to such BET
Compound, such Go Decision shall be disregarded for purposes of this Agreement, and this paragraph (d) (and not paragraph (e) below) shall apply to the next Go Decision thereafter, if any. 

(e)    If LLS makes a Go Decision for more than one BET Compound, then, promptly following the second and each subsequent
Go Decision, Company and LLS shall diligently negotiate in good faith the terms of a separate agreement for the funding, research, development and commercialization of the applicable BET Compound in the Field, which agreement the Parties anticipate
shall contain terms substantially equivalent to those in this Agreement, but with Funding, Milestones, Research Plan and Budget that are appropriate for the applicable BET Compound. Company’s obligation to enter into any such separate agreement
shall be subject to Company’s receipt of any required consent, which include but are not limited to any consent that may be required from Genentech Inc. and/or Company’s stockholders, which consents Company shall use good faith efforts to
obtain. If the Parties, despite diligent good faith efforts, have not entered into such separate agreement with respect to a BET Compound within [**] after the applicable Go Decision, neither Party shall have any obligation to the other Party with
respect to such BET Compound.” 
 7.    Section 12.1 is hereby amended to read in its entirety as follows: 

“12.1 Term and Termination. This Agreement shall become effective as of the Effective Date and, unless earlier terminated pursuant
to the other provisions of this Section 12, shall terminate (a) on the first anniversary of the First Amendment Date if LLS does not make a Go Decision prior to such date, or (b) if LLS makes a Go Decision prior to such date, when
there are no longer any payment obligations owing from Company to LLS pursuant to Section 9.3, or, if applicable, from LLS to Company pursuant to Section 9.5. If this Agreement terminates pursuant to clause (a) of this
Section 12.1, Company shall return to LLS within [**] after termination the $[**] in unexpended Funding that Company held as of the First Amendment Date, which obligation shall survive such termination. If LLS makes a Go Decision prior to the
first anniversary of the First Amendment Date, LLS shall have the right to terminate the Agreement on ninety (90) days’ notice if any of the following occurs: (x) any Projected Date listed for a development Milestone in Exhibit C is
delayed by more than one hundred twenty (120) days (a “Program Delay”) and LLS and Company decide by mutual agreement that the program has suffered irreparable damage that would not be remedied even by undertaking reasonable efforts
to address the cause of the Program Delay, such that the long-term viability of 







 
the program is put into question; provided, however, that if a Program Delay occurs that does not result in termination under this clause, then all subsequent Projected Dates will be
correspondingly adjusted to reflect the actual delay in achieving the Milestone in question; (z) LLS determines that it has insufficient funds to complete the full Funding under the Agreement, as determined by a Board Directive to cut
Program(s) Funding,” 
 8.    The Parties hereby confirm and agree that, except as amended by this First Amendment, the Agreement
remains in full force and effect and is a binding obligation of the Parties. The provisions of Section 14 (Miscellaneous Provisions) are hereby incorporated by reference herein, mutatis mutandis.
