 CONFIDENTIAL EXECUTION VERSION

  

 (g) Transfer of Collaboration Compounds. Within [**] after the completion of
the Draft Pool selection processes pursuant to Section 2.11, the Researching Parties shall consult regarding their then existing supply of Collaboration Compounds. If a Researching Party determines that it has in its possession a materially
smaller quantity of any Collaboration Compound as compared to the quantity in the Control of the other Researching Party, then it shall so notify such other Research Party and such other Researching Party shall transfer to such Researching Party a
sufficient amount of such Collaboration Compound such that each Researching Party shall have approximately equal amounts of such Collaboration Compound. 

2.8 Funded Constellation FTEs. 

(a) Generally. Subject to the payment of the Committed Funding in accordance with Sections 5.2 and 6.3, Constellation
shall provide Constellation FTEs for performance of the research and other activities for which Constellation is responsible under the Research Plan. Each individual included in the funded FTEs shall possess a bachelor’s degree or higher
in a relevant scientific discipline and shall be experienced in the type of research or other activities to be performed by such individual under the Research Plan. At Genentech’s request, Constellation shall provide resumes or curricula
vitae for funded FTEs in order for Genentech to ensure such individuals have the appropriate qualifications. 
 (b) Number of
FTEs. While the actual number of FTEs may fluctuate on a month-to-month basis, Constellation shall commit to the Research Collaboration, and, in which case,
Genentech shall fund, (i) for the Initial Research Term, (A) [**] Constellation FTEs in the first year; (B) [**] Constellation FTEs in the second year, and (C) [**] Constellation FTEs in the third year, and (if applicable) (ii) for the
First Extended Research Term, [**] Constellation FTEs. On an annual basis, Genentech shall have no FTE support payment obligation for any number of Constellation FTEs beyond the number of Constellation FTEs set forth in this Section 2.8(b),
provided, however, with respect solely to the Initial Research Term, the actual number of Constellation FTEs may fluctuate by up to [**] Constellation FTEs each year; provided further that Genentech will not have any FTE
support payment obligation for, and Constellation shall not be required to commit, more than [**] in total over the Initial Research Term. 

(c) Constellation Key Employees. While employed by Constellation or an Affiliate of Constellation, the Constellation Key Employees shall
devote work-time to the Research Collaboration as reasonably necessary to diligently fulfill Constellation’s responsibilities under the Research Collaboration, including its obligations under Section 2.3(b) to use Diligent Efforts to

 CONFIDENTIAL EXECUTION VERSION

  

 2.9 Permitted Contractors. 

(a) Constellation’s Permitted Contractors. Other than Permitted Contractors who are chemists (which are
addressed in Section 2.9(c)), if specified in the Research Plan, or agreed to in writing by the JRC, Constellation may, in accordance with Section 2.10, use Permitted Contractors to perform Constellation’s activities under the
Research Plan, provided Constellation shall ensure such activities are subject to a written agreement under which such Permitted Contractor is permitted to use and transfer such Research Collaboration Materials only in accordance with
Section 2.7. 
 (b) Genentech’s Permitted Contractors. Genentech may, at Genentech’s expense, use Permitted
Contractors to perform Genentech’s activities under the Research Plan, provided Genentech shall ensure such activities are subject to a written agreement under which such Permitted Contractor is permitted to use and transfer such
Research Collaboration Materials only in accordance with Section 2.7. 
 (c) Permitted Contractor Chemists. Genentech, at
Genentech’s expense, shall be responsible for engaging any Permitted Contractors that are chemists to carry out activities under the Research Plan. On a
project-by-project basis Constellation may directly manage a specific number of such Permitted Contractor chemists, in accordance with the strategy laid out by the JPT
and the JRC. For each project, the number of such Permitted Contractor chemists to be managed by Constellation shall be determined by the JRC. 

(d) Institutional Collaborations. Any proposal by either Party to work with an Institutional Collaborator in order to perform
activities under the Research Plan must be reviewed and mutually approved by the Parties. 
 2.10 Costs Other than for Funded
Constellation FTEs. Except as otherwise expressly provided in this Agreement (including the inclusion in FTE Payments of the items set forth in Exhibit F), the Researching Parties shall determine in good faith the allocation of
any out-of-pocket costs (other than the items set forth in Section 2.9(c) or Exhibit F) incurred in performing activities under the Research Plan;
provided, however, that neither Researching Party shall be obligated to bear such costs or to be responsible for any activity resulting in out-of-pocket
costs, without such Researching Party’s consent. For clarity, any out-of-pocket costs incurred by Constellation in performing its activities under the Research Plan
for the items set forth in Exhibit F shall in all cases be allocated to Constellation and deemed included as part of the FTE Rate. 

2.11 Target Selection and Further Development. 

(a) Creation of Draft Pool. Throughout the Research Term, following the guidelines set forth in Exhibit C, the JRC shall
keep a running list of Targets that might be eligible for selection under the Draft Pool. Not later than [**] prior to the last day of the Initial Research Term (or the First Extended Research Term if so extended) (the “Draft Pool
Date”), the JRC will create a list of [**] (or such lower number as the Researching Parties may agree to) (such number the “Draft Pool Capacity”) Draft Pick Targets (the “Draft Pool”). Draft Pick Targets in
the Draft Pool will be divided up in accordance with this Section 2.11 for further development by the Parties. 

  
 22 









 CONFIDENTIAL EXECUTION VERSION

  

 (b) Compound Criteria. 

(i) Not later than the Draft Pool Date, for each Draft Pick Target included in the Draft Pool, the JRC will set specific criteria defining the
related compound parameters (e.g., potency/selectivity of compounds, etc.) (the “Compound Criteria”) for a compound to be considered a Collaboration Compound for a particular Draft Pick Target. The Compound Criteria for each Draft
Pick Target will be as narrow as reasonable based on the science available at the time. 
 (ii) If a compound meets the Compound Criteria
associated with a Draft Pick Target that is exclusively licensed to a Party, and if the Party who is not exclusively licensed such Draft Pick Target can demonstrate that the compound’s activity is due to modulation of a target that is not the
exclusively licensed Draft Pick Target (as demonstrated by a biochemical, cellular and/or in vivo PD model), then the Parties will discuss in good faith whether such compound should be deemed not to meet the Compound Criteria definition for the
applicable Draft Pick Target. During such discussions, each Party shall give due consideration to all scientific information presented by the other Party. Following such discussions, either Party may make a written request to the other Party to deem
such compound as not meeting the Compound Criteria for the applicable Draft Pick Target. Such other Party shall not unreasonably withhold its consent to such request. 

(c) Resolution of Draft Pool and Compound Criteria Disputes. If the JRC is unable to agree on the inclusion of a Target as a
Draft Pick Target in the Draft Pool, or upon final Compound Criteria for any Draft Pick Target, by the Draft Pool Date, then the Researching Parties shall finalize such Draft Pool within the [**] thereafter as follows, with each Researching Party
making its selection within a period equal to [**] per Target specified in clauses (i) or (ii) (subject to clauses (iii) and (iv)), as applicable: 

(i) [**] shall have the right to select [**] additional Targets to include in such Draft Pool and shall create the associated Compound
Criteria following the guidelines set forth on Exhibit D (the “Compound Criteria Guidelines”) therefor; provided that [**] may select [**] for inclusion if the Draft Pool would reach the applicable Draft Pool Capacity
following such selection. 
 (ii) If, following any inclusion of additional Targets pursuant to the preceding clause (i), the Draft
Pool has not reached the Draft Pool Capacity, [**] shall have the right to select [**] to include in the Draft Pool and shall create the associated Compound Criteria following the Compound Criteria Guidelines therefor. 

(iii) If, following any inclusion of the additional Target pursuant to the preceding clause (ii), the Draft Pool has not reached the
applicable Draft Pool Capacity, additional Target(s) may be selected for inclusion in the Draft Pool by the alternating application of the preceding clauses (i) and (ii) until the Draft Pool reaches the applicable Draft Pool Capacity or the
Parties otherwise agree to finalize the Draft Pool beneath the Draft Pool Capacity. 

  
 23 









 CONFIDENTIAL EXECUTION VERSION

  

 (iv) For clarity, (A) in creating the Compound Criteria for the relevant Draft
Pick Target, the applicable Party shall follow the guidelines set forth on Exhibit D, and (B) the inclusion by a Party of a Target in the Draft Pool in no way reserves such Target for such Party. 

(d) Draft Pick Targets. Within the [**] after the Draft Pick Targets and Compound Criteria are finalized, Draft Pick Targets will
be selected, in writing, by each of the Researching Parties. Selections will be made as follows: 
 (i) if [**] or more Targets have
achieved LSR-Go on the Draft Pool Date (whether or not such Targets are Draft Pick Targets), then selection will be made in the following sequence: 

 

	 	•	 	first [**] shall have [**] to select [**], 

  

	 	•	 	then [**] shall have [**] to select [**], 

  

	 	•	 	then [**] shall have [**] to select [**], 

  

	 	•	 	then [**] shall have [**] to select [**], 

  

	 	•	 	then [**] shall have [**] to select [**], 

  

	 	•	 	then [**] shall have [**] to select [**], and 

  

	 	•	 	then [**] shall have [**] to select [**]; and 

 (ii) otherwise, selection will be made
in the following sequence: 
  

	 	•	 	first [**] shall have [**] to select [**] (subject to clause (iii)), 

  

	 	•	 	then [**] shall have [**] to select [**], 

  

	 	•	 	then [**] shall have [**] to select [**], 

  

	 	•	 	then [**] shall have [**] to select [**], 

  

	 	•	 	then [**] shall have [**] to select [**], and 

  

	 	•	 	then [**] shall have [**] to select [**]; 

 (iii) if clause (ii) applies, then [**]
may not, as a result of selecting its fourth (4th) Draft Pick Target, select all of the Targets in the Draft Pool from a particular Class (unless there is [**] in the Draft Pool from such Class) unless [**], during its [**] initial selection period,
first offers such Target(s) to [**], in which case [**] shall have [**] to (A) select such Target(s) as [**] first Draft Pick Target, or (B) decline such Target(s) as [**] first 

  
 24 









 CONFIDENTIAL EXECUTION VERSION

  

 
Draft Pick Target, in which case [**] may, during the remainder of such [**] period plus [**], select such Target. For clarity, [**] is in no way limited in its selection of any Draft Pick
Target, other than its selection of its fourth Draft Pick Target under subsection 2.11(d)(ii). 
 (iv) A Party’s failure to make
its Draft Pick Target selection(s) within the time allotted in clause (i), (ii) or (iii) above shall not prevent the other Party from making its selection in the subsequent bullet. 

(e) Draft Pick Target Table and Definitions. Table 1 below illustrates the foregoing selection process. Draft Pick Targets
selected by Genentech are referred to as “Genentech Draft Pick Targets”, and Draft Pick Targets selected by Constellation are referred to as “Constellation Draft Pick Targets”.

Product, then Net Sales shall be calculated by multiplying Net Sales (as calculated without regard to this paragraph) by the fraction A/(A+B), where A is the average selling price of the Collaboration Compound component of the Combination Product,
when sold separately as a stand-alone product in the applicable country, and B is the average selling price of the component of the Combination Product comprising the other active pharmaceutical ingredient(s), when sold separately as a stand-alone
product in such country. If both the Licensed Product component and such other component of the Combination Product are not sold separately and the Parties are not able to agree, within [**] after it first being raised for discussion, on the
appropriate adjustment to Net Sales based on the relative commercial values of the components of the Combination Product, or if there is any other dispute regarding the calculation of Net Sales pursuant to this paragraph, then the appropriate
adjustment to Net Sales will be determined by a single expert jointly appointed by the Parties within a further [**] based on the relative commercial value contributed by the components of the Combination Product. In the absence of an agreement on
the appointment of the expert, either Party may have such expert appointed by the American Arbitration Association. The decision of the expert shall be final and binding on the Parties and the fees of the expert shall be shared equally between
Constellation and Licensee.

 CONFIDENTIAL EXECUTION VERSION

  

 (e) Late Payments. To the extent that any payments under this Agreement are not
paid within the specified time period, such outstanding payments shall accrue interest from the date due, at the one year LIBOR rate (as reported in Reuters) on the last Business Day of the applicable calendar quarter prior to the date on which such
payment was due, plus [**] percentage points, calculated on the basis of a 360-day year, or, if lower, the maximum rate permitted by law. 

(f) Blocked Currency. If, at any time, legal restrictions prevent the applicable Commercializing Party (or its Sublicensee) from
remitting part or all of a Royalty Payment when due with respect to any country in the Territory where Licensed Products are sold, the Commercializing Party shall promptly notify the other Party thereof in writing and shall continue to provide Net
Sales Reports for such Royalty Payments. Such Royalty Payments shall continue to accrue in such country, and the Commercializing Party shall deposit such payment in local currency in such country to the credit of the other Party in a recognized
banking institution designated by such other Party in writing or, if no such banking institution is designated by such other Party within a period of [**] after receipt of written notice from the Commercializing Party hereunder, in a recognized
banking institution selected by the Commercializing Party and identified in a written notice given to such other Party, but the Commercializing Party shall not otherwise be obligated to make such Royalty Payments until such time as payment may be
made through reasonable, lawful means or methods that may be available, as the Commercializing Party shall reasonably determine. 

(g) Taxes. 

(i) Each Party shall comply with applicable laws and regulations regarding filing and reporting for income tax purposes. The Parties
agree that their relationship under this Agreement does not constitute, and neither Party shall treat such relationship as, a partnership or other type of entity for any tax purposes. All payments made under this Agreement shall be free and clear of
any and all taxes, duties, levies, fees or other charges, except for withholding taxes. Each Party shall be entitled to deduct from its payments to the other Party under this Agreement the amount of any withholding taxes required to be withheld, to
the extent paid to the appropriate governmental authority on behalf of the other Party (and not refunded or reimbursed). 
 (ii)
Notwithstanding Section 6.3(g)(i), if a Party (the “Paying Party”) is required to make a payment to the other Party that is subject to a deduction or withholding of tax by a taxing authority located in a jurisdiction (the
“Other Jurisdiction”) other than the United States (or any political subdivision thereof) or Switzerland (or any political subdivision thereof), and if the Paying Party is obligated to deduct any withholding taxes from such payment
because this Agreement has been transferred, assigned or sublicensed by the Paying Party (or because, for any reason, a person other than one of the original Parties to this Agreement will make such payment), then the sum payable by the Paying Party
(in respect of which such deduction or withholding is required to be made) shall be increased to the extent necessary to ensure that the Party receiving such payment receives a sum equal to the sum which it would


  
 44 









 CONFIDENTIAL EXECUTION VERSION

  

 
have received if no such transfer, assignment, sublicense or substitution of the payor had occurred; provided, however, that no such additional amount shall be paid pursuant to this
Section 6.3(g)(ii) with respect to taxes that are attributable to failure of the Party receiving such payment to comply with the requirements of Section 6.3(g)(iii) below. 

(iii) Each Party shall deliver to the other Party, upon request, proof of payment of all withholding taxes imposed with respect to any
payments made to the other Party hereunder. Each Party shall provide reasonable assistance to the other Party in seeking any reduction or elimination available to the other Party pursuant to any relevant law, regulation or double tax treaty with
respect to any withholding tax imposed on payments hereunder. Without limiting the generality of the foregoing, if a Party can cause any such withholding tax to be reduced or eliminated by providing the other Party with a properly completed and
executed certificate or other document, or by filing any such certificate or other document received from the other Party with a taxing jurisdiction, then each such Party shall take such action on a timely basis in order that such reduction or
elimination can be obtained. In the event any Party fails to take any action required by this Section 6.3(g)(iii), then, notwithstanding the other provisions of this Section 6.3(g), the failing Party shall be responsible for any additional
withholding taxes (or payments under this Section 6.3(g) on account of withholding taxes) required to be borne by the Party failing to act or the other Party on account of such failure and shall either (a) if the Party is the Paying Party,
make a payment to the other Party to the extent necessary to ensure that the Party receiving such payment is placed in the same position that it would have been in if such failure had not occurred or (b) if the Party is not the Paying Party,
not be entitled to an additional payment under this Section 6.3(g) with respect to withholding taxes, as applicable. The Parties agree to use commercially reasonable efforts to avoid the necessity to make any such payments to each other. 

(iv) If a Party (the “Recipient Party”) receives a refund with respect to any withholding taxes for which the other
Party has made a payment to or on behalf of the Recipient Party pursuant to Section 6.3(g)(ii), then the Recipient Party shall pay to the Paying Party an amount equal to such refund (but only to the extent of additional amounts received by the
Recipient Party pursuant to Section 6.3(g)(ii) with respect to the taxes giving rise to such refund) without interest (other than any interest paid by the relevant governmental authority with respect to such refund or credit). Payments, if
any, under this Section 6.3(g)(iv) shall be paid by the Recipient Party promptly following the receipt of a refund. If, with respect to the payments contemplated by this Section 6.3(g)(iv), any taxing authority requires a return
of all or any portion of a refund (an “Adjustment”), then the Party that received a payment under this Section 6.3(g)(iv) shall pay the Recipient Party an amount equal to the Adjustment. 

6.4 Records, Audits and Other Financial Provisions. 

(a) Records. Constellation shall keep complete and accurate records for a period of at least [**] (or the shorter period required
under Section 6.4(c)) for each reporting period during which FTE Payments are due, showing the particulars necessary in sufficient detail to enable FTE Reports to be verified. The applicable Commercializing Party shall keep,


  
 45 









 CONFIDENTIAL EXECUTION VERSION

  

 
and shall require its Affiliates and Sublicensees to keep, full, true and accurate books of account containing all particulars that may be necessary for the purpose of calculating all royalties
and other amounts payable under this Agreement. Such books of accounts shall be kept at such Party’s principal place of business. 

(b) Audits. Upon timely request and at least [**] prior written notice from the auditing Party, at the expense of the auditing
Party, the auditing Party may have an independent public accountant reasonably acceptable to the audited Party perform, on behalf of the auditing Party, an audit of such books and records of the other Party and its Affiliates and its Sublicensees
that are deemed necessary by the auditing Party’s independent public accountant to report on FTE Reports, or Net Sales of Licensed Product for the period or periods requested by the auditing Party and the correctness of any report or payments
made under this Agreement. Such audit shall be conducted in the countries specifically requested by the auditing Party, during regular business hours in such a manner as to not unnecessarily interfere with the other Party’s normal business
activities, and shall be limited to results in the [**] prior to audit notification. Such audit shall not be performed more frequently than [**] nor more frequently than [**] with respect to records covering any specific period of time. 

(c) Confidentiality. All information, data documents and abstracts referred to in this Section 6.4 shall be used only for
the purpose of verifying royalty statements and other payments due under this Agreement, shall be treated as the audited Party’s Confidential Information subject to the obligations of this Agreement and need neither be retained more than [**]
after completion of an audit hereof, if an audit has been requested; nor more than [**] from the end of the calendar year to which each shall pertain; nor more than [**] after the date of expiration or termination of this Agreement. 

(d) Sharing of Draft Reports. The auditors shall share all draft reports with the audited Party before the draft
report is shared with the auditing Party and before the final document is issued; the auditors shall not have the right to make any legally binding interpretations of this Agreement. The final report shall be shared by the Parties. 

(e) Over-or Underpayment. If the audit reveals an overpayment to the auditing Party, the
auditing Party shall reimburse the other Party for the amount of the overpayment within [**]. If the audit reveals an underpayment to the auditing Party, the audited Party shall make up such underpayment with the next royalty payment or, if no
royalty payment is or will be due within the [**] after completion of such audit, within [**]. The audited Party shall pay for the audit costs if its underpayment of the royalty or milestone exceeds [**] percent ([**]%) of the aggregate amount of
amounts owed with regard to the subject of the audit. Section 6.3(e) shall apply to this Section 6.4(e) if the audited Party had overstated the amount to be paid to the audited Party or understated the amount to be paid to the auditing
Party. 
 (f) Duration of Audit Rights. The failure of a Party to request verification of any royalty calculation within the
period during which corresponding records must be maintained under this Section 6.4 will be deemed to be acceptance of the royalty payments and reports.

 6.5 Rights Regarding Consolidation of Constellation Financial Data. If, at any time
until the later of the expiration or termination of the Research Term, or the termination of the Option Agreement, compliance with any term or condition of this Agreement would, in Licensee’s opinion and with the concurrence of Licensee’s
independent auditors, require Licensee to consolidate Constellation’s financial statements within Licensee’s financial statements in order to comply with accounting standards in effect at that time, then upon Licensee’s request,
Constellation shall provide to Licensee, subject to the obligations of Licensee under Article 9 regarding Confidential Information, (a) Constellation’s unaudited quarterly consolidated financial statements, prepared in accordance with IFRS
(i.e., balance sheet, income statement and statement of cash flows) for each calendar quarter to which such consolidation obligation applies within [**] after the end of the calendar quarter, (b) Constellation’s forecasted results for a
given calendar quarter to which such consolidation obligation applies, based on its best available estimates, no earlier than [**] prior to, and no later than [**] prior to, the close of such calendar quarter and (c) Constellation’s
board-approved budget for each calendar year. The forecasted results described in subsection (b) above must be based on at least [**] of actual results and will encompass all of the financial statements noted above. Licensee
acknowledges that such forecasted results will be a good faith estimate only and will not be binding in any way upon Constellation. Notwithstanding anything to the contrary, upon Licensee’s initial request to consolidate Constellation
financial data under this provision, Constellation may provide the initial unaudited quarterly financial statements prepared in accordance with US GAAP and not IFRS; provided, that, Constellation provides all reasonable assistance to Licensee
in the restatement of such initial financial statements into IFRS. Licensee shall reimburse Constellation for reasonable, out-of-pocket, Third Party costs paid by
Constellation in connection with its compliance with this Section 6.5; provided such amounts do not, without Licensee’s prior written consent, exceed [**] U.S. Dollars ($[**]), including any costs incurred by Constellation required to
prepare or restate its financial statements in accordance with IFRS (if Constellation is then using US GAAP). 
 6.6 Limitations on Bundle
Discounts. If one or more Licensed Products is sold together with other products in a bundle or package of products (a “Bundled Sale”) offered to customers by a Commercializing Party (or its Affiliate or Sublicensee), and
discounts on the products in any such Bundled Sale including Licensed Products are granted to the purchaser by the Commercializing Party (or its Affiliate or Sublicensee) as part of such sale, then such Commercializing Party agrees that, for the
purposes of calculating Net Sales hereunder, the purchase price allocated to the Licensed Product will be based on the ratio of its list price to the aggregate list price of all products in the bundle.

Patent or are neither a Constellation Collaboration Patent or a Genentech Collaboration Patent, then, except as set forth in Section 7.3(d)(iv) below or otherwise agreed to by the Parties, such Collaboration Patents shall be Prosecuted and
Maintained in accordance with Section 7.3(c) (disregarding any references therein limiting its application to the Research Term or requiring only Genentech, and not Roche, to exercise the rights thereunder). 

(iv) Notwithstanding Section 7.3(d)(iii), Collaboration Patents directed to an LO Compound first synthesized by or on behalf of
Constellation shall be deemed “Constellation Collaboration Patents” and Collaboration Patents directed to an LO Compound first synthesized by or on behalf of Licensee shall be deemed “Genentech Collaboration Patents.” 

7.4 Patent Interferences or Derivation Proceedings. If an interference or a derivation proceeding is declared by the US Patent and
Trademark Office between one or more of the Patents owned by Constellation and Licensee, and such declared interference or derivation proceeding does not involve any Patents owned by a Third Party, then to the extent such Patents claim a
Collaboration Compound, Licensed Product or Companion Diagnostic, the Parties shall in good faith establish a mutually agreeable process to resolve such interference or derivation proceeding in a reasonable manner in conformance with all applicable
legal standards, but with the goal to not prejudice either Party. 
 7.5 Inventorship; CREATE Act. 

(a) Inventorship. The determination of inventorship of Research Collaboration Inventions shall be made in accordance with United

 CONFIDENTIAL EXECUTION VERSION

  

 (b) CREATE Act. It is the intention of the Parties that this Agreement is a
“joint research agreement” as that phrase is defined in Public Law 108-453 (the “CREATE Act”). In the event that either Party to this Agreement intends to overcome a rejection of a
claimed invention within the Research Collaboration IP pursuant to the provisions of the CREATE Act, such Party shall first obtain the prior written consent of the other Party. Following receipt of such written consent, such Party shall limit any
amendment to the specification or statement to the US Patent and Trademark Office with respect to this Agreement to that which is strictly required by 35 USC § 103(c) (or as otherwise reflected under the America Invents Act) and
the rules and regulations promulgated thereunder and which is consistent with the terms and conditions of this Agreement (including the scope of the Research Collaboration). To the extent that the Parties agree that, in order to overcome a rejection
of a claimed invention within the Research Collaboration IP pursuant to the provisions of the CREATE Act, the filing of a terminal disclaimer is required or advisable, the Parties shall first agree on terms and conditions under which the patent
application subject to such terminal disclaimer and the patent or application over which such application is disclaimed shall be jointly enforced, to the extent that the Parties have not previously agreed to such terms and conditions. In the event
that a Party enters into an agreement with a Third Party with respect to the further research, development or commercialization of a Collaboration Compound, Companion Diagnostic, or Licensed Product, the Parties shall, upon such Party’s
request, discuss whether the other Party should similarly enter into such agreement with such Third Party for the purposes of furthering the Parties’ objectives under this Agreement, provided that such agreement does not place any
material obligation on such other Party. 
 Article 8 

Enforcement and Defense of IP; Defense of Third Party Infringement Claims 

8.1 Notice. With respect to intellectual property that is within the scope of the licenses under Section 4.4 (for the purposes of

 CONFIDENTIAL EXECUTION VERSION

  

 (ii) Field Infringement. Notwithstanding the foregoing,
if the Infringement of the Constellation Licensed IP or the Constellation Other IP results from a Third Party’s making, using, importing, offering for sale or selling of a compound that meets the Compound Criteria for a Genentech Draft Pick
Target which is (at such time) exclusively licensed to Licensee under this Agreement (a “Field Infringement”), then Licensee shall have the sole right (but not the obligation) to seek to abate any such Field Infringement of the
Constellation Licensed IP or the Constellation Other IP by a Third Party, including by filing suit against any such Third Party. Constellation shall cooperate with Licensee in any such action (as may be reasonably requested by Licensee), including,
if necessary, by being joined as a party, and Licensee shall keep Constellation updated with respect to any such action, including providing copies of all documents received or filed in connection with any such action. 

(iii) Research Collaboration IP. 
  

	 	(A)	Draft Pick Target Research Collaboration IP. Each Party will have the sole right (but not the obligation) to seek to abate any Infringement of the Research Collaboration IP for which such Party has sole
Prosecution and Maintenance rights in accordance with Section 7.3(d)(i) or Section 7.3(d)(ii) by a Third Party, or to file suit against any such Third Party. 


 

	 	(B)	Other Research Collaboration IP. For any Research Collaboration IP for which the Prosecution and Maintenance is covered by Section 7.3(d)(iii), Licensee shall have the first right (but not the obligation) to
seek to abate any such Infringement of the Research Collaboration IP by a Third Party, or to file suit against any such Third Party. If Licensee does not, within [**] of receipt of a notice under Section 8.1 (or [**] of receipt of a Paragraph
IV Notice), take steps to abate the Infringement, or file suit to enforce the Research Collaboration IP against such Third Party, Constellation shall have the right (but not the obligation) to take action to enforce the Research Collaboration IP
against such Third Party. The non-controlling Party shall cooperate with the Party controlling any such action (as may be reasonably requested by the controlling Party), including, if necessary, by being
joined as a party, and the Party controlling any such action shall keep the other Party updated with respect to any such action, including providing copies of all documents received or filed in connection with any such action.

Section 8.2(a)(ii) or (iii) shall not settle or consent to an adverse judgment (including any judgment that affects the scope, validity or enforcement of any Constellation Licensed IP, Constellation Other IP or Research Collaboration
IP) without the express written consent of the non-controlling Party (such consent not to be unreasonably withheld); provided, however, Licensee may settle or consent to an adverse judgment in
any action described in Section 8.2(a)(ii) without obtaining such consent from Constellation, unless such settlement or judgment would either (i) impose a financial obligation upon Constellation or (ii) limit the scope of or
invalidate any Constellation Licensed IP or Constellation Other IP. 
 (c) Damages. Unless otherwise agreed by the
Parties, and subject to the Parties’ respective obligations under Article 13, all monies recovered upon the final judgment or settlement of any action described in Section 8.2(a)(ii) or (iii), shall be used as follows: (i) first,
to reimburse each of Licensee and Constellation, on a pro rata basis for its out-of-pocket costs relating to such action; and (ii) second, any remaining amount
(after relevant adjustments to convert to Net Sales of Licensed Products) shall be treated as Net Sales, to be retained or paid to the Party(ies) with the right to sell the product whose sales are or would be negatively affected by the relevant
Infringement and subject to the royalty obligations set forth in Section 5.5. 
 8.3 Defense of Patents. If a Third Party brings
a claim of invalidity, unenforceability or non-infringement of a given Patent within the Constellation Licensed IP, the Constellation Other IP or the Research Collaboration IP (e.g., a declaratory
judgment action or a nullity proceeding), the Party that has final decision making authority (and is responsible for the out-of-pocket costs for the Prosecution and
Maintenance of such Patent) at the time such claim is brought (in accordance with Section 7.3), shall be solely responsible for defending such Third Party claim, at its sole discretion and expense.  

8.4 Defense of Third Party Infringement Claims. If a Third Party brings a claim of infringement or misappropriation against a Party on
account of the manufacture, use, offer for sale, sale or import of any Collaboration Compound, Companion Diagnostic, or Licensed Product, such Party shall be solely responsible for defending such Third Party claim, at its sole discretion and
expense. At such Party’s request and expense, the other Party shall reasonably cooperate with such Party in connection with any such defense, including, if necessary, by being joined as a party.

Article 13 

Indemnification; Limitation on Liability; Insurance 

13.1 Indemnification. 

(a) Definitions. The following definitions are for purposes of Section 13.1: 

(i) “Claims” means claims, suits, actions, demands or other proceedings by any Third Party. 

(ii) “Indemnitee” means, as applicable, a Constellation Indemnitee (as defined in Section 13.1(b)) or a Licensee
Indemnitee (as defined in Section 13.1(c)). 
 (iii) “Losses” means any and all liabilities, damages,
settlements, penalties, fines, costs or expenses (including, reasonable attorneys’ fees and other expenses of litigation). 
 (b)
Indemnification by Licensee. Licensee hereby agrees to indemnify, defend (if requested by Constellation) and hold harmless each of Constellation and its officers, directors, employees and agents (for purposes of
Section 13.1, each, a “Constellation Indemnitee”) from and against Losses resulting directly from Claims to the extent attributable to (i) Licensee’s breach of its representations or warranties under this
Agreement; (ii) activities performed by Licensee under this Agreement or (iii) the discovery, development, manufacture, use, handling, storage, sale or other disposition by Licensee or its Affiliates, sublicensees or distributors after the
Research Term of Collaboration Compounds or Licensed Products, or other compounds that meet the Compound Criteria, directed to Genentech Draft Pick Targets, and related Companion Diagnostics (including any claims for product liability).
Licensee’s obligations under this Section 13.1(b) shall not apply to the extent that any such Losses are attributable to (A) Constellation’s breach of its representations or warranties under this Agreement or (B) the
negligence or willful misconduct of any Constellation Indemnitee.

  
 67 









 CONFIDENTIAL EXECUTION VERSION

  

 (c) Indemnification by Constellation. Constellation hereby agrees
to indemnify, defend (if requested by Licensee) and hold harmless each of Licensee and its officers, directors, employees and agents (for purposes of Section 13.1, each, a “Licensee Indemnitee”) from and against Losses
resulting directly from Claims to the extent attributable to (i) Constellation’s breach of its representations or warranties under this Agreement, (ii) activities performed by Constellation under this Agreement or (iii) the
discovery, development, manufacture, use, handling, storage, sale or other disposition by Constellation or its Affiliates, sublicensees or distributors after the Research Term of Collaboration Compounds or Licensed Products, or other compounds that
meet the Compound Criteria, directed to Constellation Draft Pick Targets, and related Companion Diagnostics (including any claims for product liability). Constellation’s obligations under this Section 13.1(c) shall not apply to the extent
that any such Losses are attributable to (A) Licensee’s breach of its representations or warranties under this Agreement or (B) the negligence or willful misconduct of any Licensee Indemnitee. 

(d) Indemnification Procedures. The Indemnitee shall (i) notify the indemnifying Party (the “Indemnitor”)
of any Claim for which it seeks to exercise its rights under Section 13.1(b) or (c) as soon as reasonably possible after it receives notice of such Claim; (ii) permit the Indemnitor to assume the sole control of the defense thereof,
including the right to settle or conclude such defense (so long as such settlement does not, with the Indemnitee’s consent, admit liability on the part of the Indemnitee), with counsel mutually satisfactory to the Parties; (iii) cooperate
as reasonably requested (at the expense of Indemnitor) in the defense of such Claim; and (iv) not settle such Claim without the express, prior written consent of the Indemnitor. Notwithstanding the foregoing, and subject to this
Section 13.1(d)(i), (iii), and (iv), if the Claim relates to a compound that is directed to a Draft Pick Target of the Indemnitee and meets the Compound Criteria therefor or any product containing such compound (including, without limitation, a
Licensed Product or Companion Diagnostic) that the Indemnitee or its Affiliate is then commercializing, the Indemnitee shall have the right to retain control of the defense thereof, with the participation of the Indemnitor. 

(e) Limitations. The failure of an Indemnitee to deliver notice to the Indemnitor within a reasonable time after the
commencement of any Claim for which such Indemnitee seeks to exercise its rights under Section 13.1, to the extent prejudicial to the Indemnitor’s ability to defend such Claim, shall relieve the Indemnitor of its obligation to the
Indemnitees under Section 13.1. The Parties agree that only Constellation or Licensee may seek to exercise the rights under Section 13.1 (on its own behalf or on behalf of its Indemnitees), and other Indemnitees may not directly seek to
exercise such rights. 
 13.2 Limitation on Liability. EXCEPT WITH RESPECT TO A MATERIAL BREACH BY GENENTECH OF
ITS OBLIGATIONS UNDER SECTION 2.4(c), IN NO EVENT SHALL EITHER PARTY BE LIABLE TO THE OTHER PARTY FOR ANY 

  
 68 









 CONFIDENTIAL EXECUTION VERSION

  

 
CONSEQUENTIAL, INDIRECT, INCIDENTAL OR PUNITIVE DAMAGES, HOWEVER CAUSED, ARISING FROM OR RELATING TO THIS AGREEMENT OR ANY BREACH OF THIS AGREEMENT OR ANY CLAIM ARISING HEREUNDER,
PROVIDED, HOWEVER, THAT NOTHING IN THIS SECTION 13.2 IS INTENDED TO LIMIT THE RIGHTS OR OBLIGATIONS OF EITHER PARTY UNDER SECTION 13.1.  

13.3 Insurance. 

(a) General. Each Party shall maintain insurance coverage as set forth in this Section 13.3 at its own cost;
provided, however, Licensee has the right, in its sole discretion, to self-insure, in part or in whole, for any such coverage. Insurance coverage shall be primary insurance with respect to each
Party’s own participation under this Agreement and shall be maintained with an insurance company or companies having an A.M. Best’s rating (or its equivalent) of A-VII or better. On request,
each Party shall provide to the other Party certificates of insurance evidencing the insurance coverage required under this Section 13.3. Each Party shall provide to the other Party at least [**] notice of any cancellation, nonrenewal or
material change in any of the required insurance coverages. 
 (b) Commercial General Liability Insurance. Each Party
shall maintain commercial general liability insurance (for purposes of this Section 13.3(b), “CGL insurance”), (including contractual liability, personal advertising and products/completed operations coverage) with
limits no less than US$[**] per occurrence and US$[**] in the aggregate. The CGL insurance policies shall be an occurrence form, but if only a claims-made form is available to a Party, such Party shall
maintain the insurance coverage for at least [**] after such Party completes performance of its obligations under this Agreement. Each Party shall name the other Party as an additional insured under its CGL insurance policy. 

(c) Workers’ Compensation and Employers’ Liability Insurance. Each Party shall maintain (i) workers’
compensation insurance, according to applicable law and (ii) employers’ liability insurance, in the minimum amount of [**] U.S. dollars ($[**]). Each Party agrees to waive its right of subrogation with respect to workers’ compensation
claim. 
 (d) Additional Coverages. In addition, subject to the right to self insure pursuant to Section 13.3, each Party shall
obtain and maintain comprehensive insurance, including, as applicable, general liability, clinical trial liability, product liability and workers compensation insurance, customary in the industry for companies of similar size conducting similar
business. 
 Article 14 

Dispute Resolution 

14.1 Internal Resolution. Except as otherwise expressly provided in this Agreement, any Disputes shall be first referred to an
Executive of each Party for resolution, prior to proceeding under the other provisions of this Article 14. A Dispute shall be referred to such Executives upon one Party providing the other Party with written notice that such Dispute exists, and such
Executives shall attempt to resolve such Dispute through good faith discussions. In the event that such Dispute is not resolved within [**] of such other Party’s receipt of such notice, then subject to Section 14.3, either Party may
initiate by written notice to the other the Dispute resolution provisions in Section 14.2. The Parties agree that any discussions between such Executives regarding such Dispute will not constitute settlement discussions, unless the Parties
agree otherwise in writing. 

  
 69 









 CONFIDENTIAL EXECUTION VERSION

  

 14.2 Arbitration. 

(a) Rules. Except as otherwise expressly provided in this Agreement (including under Section 14.3), the Parties agree that
any Dispute not resolved internally by the Parties pursuant to Section 14.1 shall be resolved through binding arbitration conducted by the American Arbitration Association in accordance with the then-prevailing Commercial Arbitration Rules of
the American Arbitration Association (for purposes of Article 14, the “Rules”), except as modified in this Agreement, applying the substantive law specified in Section 15.2. The demand for arbitration and counterclaim shall
each include a statement setting forth the issues in dispute that are being presented for resolution through binding arbitration. In no event shall a demand for arbitration be made after the date when institution of a legal or equitable proceeding
based upon such Dispute would be barred by the applicable statute of limitations as determined from the date such Dispute was referred to the arbitrators in accordance with this Section 14.2. 

(b) Arbitrators; Location. Each Party shall select one (1) independent arbitrator, and the two (2) arbitrators so
selected shall choose a third independent arbitrator. All three (3) arbitrators shall serve as neutrals and have at least ten (10) years of (i) dispute resolution experience (including judicial experience) or (ii) legal or
business experience in the biotech or pharmaceutical industry. In any event, at least one (1) arbitrator shall satisfy the foregoing experience requirement under clause (ii). If a Party fails to nominate its arbitrator within [**] after
commencement of procedures under this Section 14.2, or if the Parties’ arbitrators cannot agree on the third arbitrator within [**], the necessary appointments shall be made in accordance with the Rules. Once appointed, neither Party shall
have any ex parte communication with any arbitrator. The arbitration proceedings shall be conducted in San Francisco, California if Constellation initiates the arbitration or in Boston, Massachusetts if Licensee
initiates the arbitration. The Parties shall take all reasonable actions to complete the selection of the arbitrators and commence the proceeding under this Section 14.2 as promptly as possible but in no event later than [**] after the
initiation of any Dispute under this Section 14.2. 
 (c) Procedures; Awards. Each Party agrees to use reasonable efforts
to make all of its current employees available, if reasonably needed, and agrees that the arbitrators may deem any party as “necessary.” Following the request by either Party, the arbitrators shall make a determination regarding
reasonable production by the Parties of documents relevant to 

  
 70 









 CONFIDENTIAL EXECUTION VERSION

  

 
the Dispute. The arbitrators shall be instructed and required to render a written, binding, non-appealable resolution and award on each issue that clearly
states the basis upon which such resolution and award is made. The written resolution and award shall be delivered to the Parties as expeditiously as possible, but in no event more than [**] after conclusion of the hearing, unless otherwise agreed
by the Parties. Judgment upon such award may be entered in any competent court or application may be made to any competent court for judicial acceptance of such an award and order for enforcement. Each Party agrees that, notwithstanding any
provision of applicable law or of this Agreement, it will not request, and the arbitrators shall have no authority to award, punitive or exemplary damages against any Party, unless otherwise permitted pursuant to Section 13.2. 

(d) Costs. The “prevailing” Party, as determined by the arbitrators, shall be entitled to (i) its share of fees
and expenses of the arbitrators and (ii) its attorneys’ fees and associated costs and expenses. In determining which Party “prevailed,” the arbitrators shall consider (i) the significance, including the financial impact, of
the claims prevailed upon and (ii) the scope of claims prevailed upon, in comparison to the total scope of the claims at issue. If the arbitrators determine that, given the scope of the arbitration, neither Party “prevailed,” the
arbitrators shall order that the Parties (i) share equally the fees and expenses of the arbitrators and (ii) bear their own attorneys’ fees and associated costs and expenses. 

(e) Interim Equitable Relief. Notwithstanding anything to the contrary in this Section 14.2, in the event that a Party
reasonably requires relief on a more expedited basis than would be possible pursuant to the procedure set forth in this Article 14, such Party may seek a temporary injunction or other interim equitable relief in a court of competent jurisdiction
pending the opportunity of the arbitrators to review the decision under this Section 14.2. Such court shall have no jurisdiction or ability to resolve Disputes beyond the specific issue of temporary injunction or other interim equitable relief.

 (f) Protective Orders; Arbitrability. At the request of either Party, the arbitrators shall enter an appropriate protective
order to maintain the confidentiality of information produced or exchanged in the course of the arbitration proceedings. The arbitrators shall have the power to decide all questions of arbitrability. 

(g) Authority. In any arbitration under this Section 14.2, the arbitrators shall have the authority to grant specific
performance (in accordance with the substantive law of Delaware) and, subject to Section 14.2(d), to allocate between the Parties the costs of arbitration in such equitable manner as they determine; provided, however, that the
arbitrators shall not have the right to amend or otherwise modify the terms of this Agreement. 
 (h) Arbitral Award. Judgment
upon the award so rendered may be entered in any court having jurisdiction or application may be made to such court for judicial acceptance of any award and an order of enforcement, as the case may be.

 14.3 Subject Matter Exclusions. Notwithstanding the provisions of Section 14.2,
any Dispute not resolved internally by the Parties pursuant to Section 14.1 that involves the validity, infringement or enforceability of a Patent included in a license granted in this Agreement (a) that is issued in the United States
shall be subject to actions before the United States Patent and Trademark Office and/or submitted exclusively to the federal court located in the jurisdiction of the district where any of the defendants reside; and (b) that is issued in any
other country (or region) shall be brought before an appropriate regulatory or administrative body or court in that country (or region), and the Parties hereby consent to the jurisdiction and venue of such courts and bodies.

Governing Law. This Agreement shall be governed by and construed under the laws of the State of Delaware without regard to conflict of laws principles. The Parties hereby exclude from this Agreement the application of the United Nations
Convention on Contracts for the International Sale of Goods. 
 15.3 Assignment. For the purposes of this Section 15.3, an
“M&A Event” means that a Third Party acquires, by merger, sale of assets or otherwise, (i) all or substantially all of the equity of a Party, (ii) all or substantially all of the assets or business of a Party to which
the subject matter of this Agreement relates or (iii) after the Research Term, all or substantially all of the assets or business of a Party with respect to a Draft Pick Target exclusively licensed to such Party (any such Third Party with
respect to clauses (i) through (iii), an “Acquirer”). On written notice to Constellation, Licensee may assign this Agreement, in its entirety, or, after the end of the Research Term, on a Draft Pick Target-by-Draft Pick Target basis, to the relevant Acquirer in connection with an M&A Event or to an Affiliate. Following the later of (a) the expiration or
termination of the Research Term or (b) the Option Termination Date (as defined 

  
 73 









 CONFIDENTIAL EXECUTION VERSION

  

 
under the Option Agreement) or termination of the Option Agreement (unless, in each case, the Option (as defined therein) has been exercised thereunder in which case Constellation may not assign
this Agreement unless and until the Merger Agreement is terminated pursuant to Section 13.1 thereof), Constellation may assign this Agreement, in its entirety or on a Draft Pick
Target-by-Draft Pick Target basis, on written notice to Licensee, (y) to an Affiliate; or (z) to the relevant Acquirer in connection with an M&A Event.
Notwithstanding any provisions of this Agreement to the contrary, if this Agreement is assigned by a Party in connection with an M&A Event, such assignment and/or the occurrence of such M&A Event (whether or not a formal assignment of this
Agreement occurs) shall not provide the other Party with rights or access to any intellectual property or technology of the relevant Acquirer. Except as expressly provided in this Section 15.3, neither Party may assign any of its rights or
delegate any of its obligations under this Agreement without the prior written consent of the other Party, such consent not to be unreasonably withheld. Subject to the foregoing, this Agreement will inure to the benefit of and bind the Parties’
successors and assigns. Any assignment in contravention of the foregoing shall be null and void. 
 15.4 Force Majeure. Neither Party
shall be deemed to have breached this Agreement for failure to perform its obligations under this Agreement to the extent such failure results from causes beyond the reasonable control of the affected Party, such causes including acts of God,
earthquakes, fires, floods, embargoes, wars, acts of terrorism, insurrections, riots, civil commotions, omissions or delays in action by any governmental authority, acts of a government or agency thereof and judicial orders or decrees. If a force
majeure event occurs, the Party unable to perform shall promptly notify the other Party of the occurrence of such event, and the Parties shall meet (in person or telephonically) promptly thereafter to discuss the circumstances relating thereto. The
Party unable to perform shall (a) provide reasonable status updates to the other Party from time to time; (b) use commercially reasonable efforts to mitigate any adverse consequences arising out of its failure to perform; and
(c) resume performance as promptly as possible. 
 15.5 Relationship of the Parties. The Parties are independent contractors, and
nothing contained in this Agreement shall be deemed or construed to create a partnership, joint venture, employment, franchise, agency or fiduciary relationship between the Parties. Genentech and Roche shall be jointly and severally liable to
Constellation for any obligations owed hereunder by Genentech, Roche or Licensee. Genentech and Roche shall coordinate their exercise of Licensee’s rights and performance of Licensee’s obligations to ensure that Constellation does not
receive duplicate or inconsistent notices or instruction with respect thereto and to ensure that Constellation is not adversely affected because Genentech and Roche each have rights hereunder. 

15.6 Amendment; Waiver. Except as otherwise expressly provided in this Agreement, no amendment to this Agreement shall be effective
unless made in writing and executed by an authorized representative of each Party. A Party’s failure to exercise, or delay in exercising, any right, power, privilege or remedy under this Agreement shall not (a) operate as a waiver thereof
or (b) operate as a waiver of any other right, power, privilege or remedy. A waiver will be effective only upon the written consent of the Party granting such waiver.

 15.7 Construction; Captions. Each Party acknowledges that it participated in the
negotiation and preparation of this Agreement and that it had the opportunity to consult with an attorney of its choice in connection therewith. Ambiguities, if any, in this Agreement shall not be construed against either Party, irrespective of
which Party may be deemed to have drafted this Agreement or authorized the ambiguous provision. Capitalized terms defined in the singular shall include the plural and vice versa. The terms “includes” and “including” mean
“includes, without limitation,” and “including, without limitation,” respectively. Titles, headings and other captions are for convenience only and shall not affect the meaning or interpretation of this Agreement.

unenforceable provisions shall be replaced by legal, valid and enforceable provisions that will achieve to the maximum extent possible the intent of the Parties, and the other provisions of this Agreement shall remain in full force and effect.

Parties with respect to the subject matter hereof and supersede and terminate all prior agreements, understandings and arrangements between the Parties with respect to such subject matter, whether written or oral, including the Prior CDA, except the
Confidential Disclosure Agreement by and among Constellation, John McCall, and Genentech, dated September 14, 2011, and the Confidential Disclosure Agreement by and among Constellation, Viksnins Harris & Padys PLLP, and Genentech,

Constellation Pharmaceuticals and Genentech Enter Broad Epigenetics Drug Discovery Collaboration 

CAMBRIDGE, Mass. – INSERT DATE – Constellation Pharmaceuticals, Inc., today announced that it has entered into a major strategic
agreement with Genentech, a member of the Roche Group (SIX: RO, ROG; OTCQX: RHHBY), to launch a broad collaboration based on the science of epigenetics and chromatin biology to discover and develop innovative treatments for cancer and other serious
diseases. 
 Under the terms of the arrangement, Constellation will receive committed funding of $95 million, comprising an upfront
payment and research funding for a three-year collaboration period. Constellation will be eligible for substantial development and commercialization milestone payments as well as up to double-digit royalties on commercial sales of multiple products
by Genentech. Additionally, Constellation will retain exclusive development and commercialization rights to selected programs emerging from the collaboration, for which payments would be due to Genentech upon the successful commercialization of such
products. 
 The parties will establish a research collaboration addressing multiple epigenetic target classes. Constellation will retain
independent strategic direction, operational management and exclusive rights to programs outside of the collaboration scope, including its two most advanced programs that are focused on the development of inhibitors of the BET chromatin reader and
EZH2 chromatin writer proteins. Genentech has a future option to acquire all outstanding shares of Constellation based on pre-negotiated terms, which include a significant initial acquisition payment plus
contingent value rights payments based on the future successful development and commercialization of multiple products by Genentech. Genentech’s option to acquire Constellation includes the BET and EZH2 programs as well as other programs
outside the collaboration scope. 
 “Genentech is a global leader in the research and development of innovative medicines, and in
combination with our class-leading product engine and deep expertise in chromatin biology will create a powerhouse dedicated to bringing the greatest benefit to patients from drugs that modulate epigenetic pathways,” said Mark A. Goldsmith,
M.D., Ph.D., president and chief executive officer of Constellation Pharmaceuticals. “This is a groundbreaking partnership in terms of the structure, breadth and potential future clinical impact of products created through our complementary
capabilities. The committed revenue and post-collaboration economics should provide a highly attractive return for our investors.”

 James Sabry, M.D., Ph.D., vice president of Genentech Partnering, added, “We believe
Constellation is a leading company in chromatin biology and epigenetics drug discovery and an excellent partner for Genentech in this area. With scientists committed to the collaboration at both Constellation and Genentech working together in a
highly integrated way, our goal is to discover and ultimately bring to market promising new therapies for patients with unmet medical needs in oncology, and potentially other therapeutic areas.” 

What is Epigenetics? 

Drug development in the field of epigenetics is directed towards the identification of small molecules that inhibit the activities of proteins
(epigenetic regulators) that add, remove or recognize various chemical modifications (or marks) to specific sites on DNA or chromosomal proteins. These marks play a key role in determining whether a gene is on or off. Epigenetic regulators are
often referred to as writers (add modifications), erasers (remove modifications) and readers (bind to chromatin). Research at Constellation and by others has shown that abnormal epigenetic regulation contributes to many different diseases. 

In research into chromatin readers that appeared recently in the Proceedings of the National Academy of Sciences Constellation
scientists demonstrated that transcription of the MYC oncogene can be suppressed using small molecule inhibitors of the BET family of chromatin adapters. MYC is a master regulator of diverse cellular functions and has long been considered a
compelling therapeutic target because of its role in many human malignancies including hematologic and solid tumors. Also, continued research by Constellation on chromatin modifying enzymes has resulted in significant progress towards developing
small molecule inhibitors of the histone lysine methyltransferase EZH2. This enzyme functions as part of a chromatin-associated protein complex implicated in the repression of gene expression. Recent cancer genomic sequencing studies have identified
recurrent mutations in the EZH2 encoding genomic locus in a subset of human cancers. In addition numerous epidemiological data sets linking increased EZH2 expression to late stage disease with poor prognosis suggest a prominent role for EZH2 in
human malignancies. 
 About Constellation Pharmaceuticals 

Constellation Pharmaceuticals leverages insights from the rapidly expanding field of epigenetics to discover and develop small molecule therapeutics for the
treatment of cancer, inflammatory/immunologic disorders and other diseases. The company’s innovative product discovery engine targets both the enzymes that modify the dynamic structure of chromatin (writers and erasers) and other proteins that
interact with chromatin (readers) to control gene expression. Restoration of normal gene expression through chromatin modulation by highly selective and specific inhibitors promises to be a powerful avenue for the development of important new
medicines against a broad range of diseases. For more information, please visit the company’s website at www.constellationpharma.com.
