3.2 Regulatory.

3.2.1 Transfer of Existing Regulatory Materials. Editas shall assign and transfer (and hereby does assign and transfer), or cause to be assigned and transferred to the extent not owned by Editas, to Juno (or its Designee), promptly (but in all cases within [**]) after the Effective Date any and all Regulatory Materials for any Licensed Products (including any Licensed RNP Complex) held or generated by or on behalf of Editas or any of its Affiliates (the “Existing Regulatory Materials”), including providing true, accurate and complete hard and electronic copies thereof to Juno. Thereafter, Juno (or its Designee) shall have the sole right, in its discretion, to file, maintain and hold title to all Existing Regulatory Materials. Notwithstanding the foregoing, at the election of Juno, Juno may notify Editas in writing that it does not desire to take assignment and transfer of certain Existing Regulatory Materials (as so determined by Juno) and in such case, Editas shall not assign or transfer to Juno (or its Designee) such designated Regulatory Materials.

3.2.2 Right of Reference; Access to Data. Pending such time as the Existing Regulatory Materials, if any, are transferred and assigned to Juno (or its Designee), or in the event of failure to transfer and assign any Existing Regulatory Materials to Juno (or its Designee), as required by Section 3.2.1, Juno (and its Designees) shall have, and Editas (on behalf of itself and its Affiliates) hereby grants to Juno (and its Designees), access and a right of reference (without any further action required on the part of Editas or any of its Affiliates, whose authorization to file this consent with any Regulatory Authority is hereby granted) to all such Existing Regulatory Materials and all data contained or referenced in any Existing Regulatory Materials for Juno (and its Designees) to exercise its rights and perform its obligations hereunder. In all cases, Juno (and its Designees) shall have access to all data contained or referenced in any Existing Regulatory Materials, and Editas shall ensure that Juno (and its Designees) are afforded such access.

3.2.3 Regulatory Matters. If Juno determines that any regulatory filings for any Licensed Products are required for any activities hereunder, including INDs, XXXx and other Regulatory Approvals (as applicable), then Juno (or its Designee) shall have the sole right, in its discretion, to seek to obtain and maintain such regulatory filings (in its or its Designee’s name). In addition, Juno (or its Designee) shall have the sole right to communicate and otherwise interact with Regulatory Authorities with respect to each Licensed Product, including with respect to any Regulatory Materials in connection therewith. Editas (and its Affiliates) shall have no right to, and shall not, make any regulatory filings related to any Licensed Products or otherwise interact with any Regulatory Authorities with respect to any Licensed Products; provided that, as and to the extent reasonably requested by Juno in writing, Editas shall interact with Regulatory Authorities in connection with Licensed Products with respect to matters related to activities conducted by or on behalf of Editas under the Master Collaboration Agreement. Notwithstanding the foregoing, until such time as a given Existing Regulatory Material, if any, is assigned and transferred to Juno in accordance with Section 3.2.1, Editas shall be responsible for all communications and interactions with Regulatory Authorities with respect to such Existing Regulatory Material; provided that, in connection with any such activities by Editas, Editas shall, to the extent reasonably requested by Juno, consult and coordinate with Juno with respect thereto (including allowing Juno to attend or participate in any meetings or other interactions with Regulatory Authorities to the extent such attendance is not prohibited or limited by such Regulatory Authority) and Editas shall accommodate and comply with any reasonable requests made by Juno in connection therewith (including that Editas shall submit to Juno a copy of any proposed filings and correspondence with any Regulatory Authority for Juno’s review and

approval prior to submission thereof). At the request of Juno, Editas shall reasonably assist Juno in communications and filings with Regulatory Authorities with respect to any Licensed Products, including in connection with the preparation of any INDs, XXXx and other Regulatory Approvals for any Licensed Products; provided that Editas shall not be required to write any portion of any application for Regulatory Approval; provided, further, that Juno will provide Editas with reasonable regulatory information as may be required in order to allow Editas to provide such assistance to Juno. For the avoidance of doubt, nothing in this Section 3.2.3 shall prevent Editas from making regulatory filings or otherwise interacting with Regulatory Authorities with respect to any RNP Complex outside of the Exclusive Field.

3.2.4 Pharmacovigilance. At the written request of Juno, promptly after such request, Editas and Juno (or its Designee(s)) will enter into a pharmacovigilance agreement reasonably acceptable to both Parties in order to, among other things, coordinate safety matters and share safety information with respect to Licensed Products.

3.3 Ongoing Transition Assistance; Technology Transfer.

Editas shall (and shall cause its Affiliates to) cooperate with Juno (and its Designees) and provide reasonable additional assistance to Juno (and its Designees) to enable Juno (and its Designees) to Research, Develop, Manufacture and Commercialize Licensed Products and Licensed RNP Complexes, as and to the extent reasonably requested by Juno, including for the following purposes (a) conducting a technology transfer to Juno with respect to the Editas Licensed Collaboration Know-How and Editas Licensed Background Know-How, including transferring hard and electronic copies thereof and any documentation (including data and protocols) included therein, in each case, to the extent not previously provided to Juno or its Designee pursuant to the Master Collaboration Agreement; (b) transfer to Juno (and its Designees) the Editas Materials, in each case, to the extent not previously provided to Juno or its Designee pursuant to the Master Collaboration Agreement; (c) providing Juno (and its Designees) reasonable assistance with respect to Manufacturing transition matters related to any Licensed RNP Complex, as more fully contemplated in Section 3.3.2; and (d) providing Juno (and its Designees) with reasonable access by teleconference or in-person (as requested by Juno) to Editas personnel (and personnel of its Affiliates and Third Party contractors) involved in the conduct of the Research Program with respect to any Licensed Program Target or Licensed RNP Complex to assist with the transition and answer questions related to the foregoing, as applicable.

3.3.2 Manufacturing Transition Assistance. As part of the Transition Assistance with respect to a given Licensed Program, as soon as reasonably practicable following a reasonable request by Juno, Editas shall transfer, and thereafter continue to transfer during the Term as may be reasonably requested by Juno from time to time, from Editas (or any of its Affiliates or its Third Party contract manufacturers, as applicable), to Juno (and its Designees), copies in English (in

writing and in an electronic format) of all data, information and other Know-How in the Control of Editas, its Affiliates and its Third Party contract manufacturers that is necessary or reasonably useful to Manufacture any Licensed RNP Complex or Licensed Products, in order to enable Juno (and its Designees) to Manufacture Licensed RNP Complexes and Licensed Products, including to replicate any process employed by or on behalf of Editas to Manufacture any Licensed RNP Complex and Licensed Products. Such transfer shall include all processes, analytical, formulation and process development data, technical memos, batch records, manufacturing process description, complete xxxx of materials (including known critical raw materials and their screening methods and acceptance criteria), analytical methods used both for product release as well as characterization, development history summary reports and supporting data and reports, cell banking qualification and stability strategy and reports. In addition, at the reasonable request of Juno from time to time, Editas shall make its employees and consultants (including personnel of its Affiliates and Third Party contract manufacturers) available to Juno (and its Designees) to provide reasonable consultation and technical assistance in order to ensure an orderly transition of the manufacturing technology and operations to Juno (and its Designees) and to assist Juno (and its Designees) in its Manufacture of any Licensed RNP Complex and Licensed Products.

3.3.3 Existing Program Agreements. At the written request of Juno, Editas shall reasonably assist Juno (or its Affiliate) in entering into new agreements directly with the counterparties to the Existing Program Agreements to cover the subject matter of any Existing Program Agreements.

3.3.4 Transition Plan. Without limiting the foregoing provisions of this Section 3.3, on a Licensed Program-by-Licensed Program basis, in order to facilitate the Transition Assistance contemplated by this Section 3.3, the Parties shall work together in good faith and establish a transition plan setting forth reasonable transition activities to be undertaken by or on behalf of Editas in order to enable the Research, Development, Manufacture and Commercialization of Licensed RNP Complexes and Licensed Products to Juno (and its Designees) with respect to the applicable Licensed Program(s) (the “Transition Plan”); provided that the Parties may mutually agree to divide out the Transition Assistance into separate Transition Plans. Once established, subject to Juno’s payment obligations with respect to Transition Assistance as set forth in Section 3.3.5, Editas shall use Commercially Reasonable Efforts to timely perform its activities under the Transition Plan.

3.3.5 Costs. The Parties agree and acknowledge that the foregoing activities conducted by Editas as set forth in this Section 3.3 shall be deemed to be the “Transition Assistance”. On a Licensed Program-by-Licensed Program basis, Juno shall be entitled to up to (a) with respect to each of the first [**] Licensed Programs (including, for clarity, the Initial Licensed Program), [**] of Transition Assistance per Licensed Program and (b) with respect to each subsequent Licensed Program thereafter, [**] of Transition Assistance per Licensed Program, in each case of (a) and (b), [**] and thereafter, subject to the reasonable availability of Editas resources, Editas shall provide additional Transition Assistance requested by Juno with respect to a Licensed Program at a reasonable hourly rate, and in accordance with a budget, in each case, to be mutually agreed by the Parties and set forth in the applicable Transition Plan.

3.4 RNP Complex Supply. At Juno’s written request, on a Licensed Product-by-Licensed Product basis, Editas will be responsible for supplying, and shall supply, to Juno (or its

Designee) Licensed RNP Complexes, for use in Research and Development by or on behalf of Juno hereunder for a period, with respect to a given Licensed Product, through the completion of the [**] for such Licensed Product (or such longer period of time as agreed in writing by the Parties); provided that Juno shall pay to Editas a reasonable, fair value cost for such supply, which cost shall be negotiated in good faith and agreed to by the Parties. Promptly following Juno’s request, the Parties shall negotiate in good faith and shall enter into a commercially reasonable supply agreement (including a quality agreement) for Editas to supply (or have supplied) Licensed RNP Complex to Juno (or its Designee) as contemplated by this Section 3.4; provided, however, that Editas shall not be obligated to provide such supply prior to the Parties entering into such supply agreement in accordance with this Section 3.4.

ARTICLE 5

EXCLUSIVITY

5.1 Exclusivity.

5.1.1 Competing Product. During the Term, except to the extent required for Editas to fulfill its obligations to Juno under and in accordance with this Agreement or the Master Collaboration Agreement, Editas shall not, and, subject to Section 5.1.2, shall ensure that its Affiliates shall not, anywhere in the world, (a) alone or with or through or for any Third Party, conduct or participate in any Research, Development, Manufacturing, Commercialization or other exploitation activities of any Competing Product; (b) grant a license, sublicense or other rights to any Third Party to conduct any of the activities in clause (a); or (c) except for the rights and licenses granted to Juno hereunder, transfer, assign, convey or otherwise sell any Competing Product; provided, however, that the foregoing shall not restrict Editas and its Affiliates from performing their obligations under (i) the Allergan Agreement as to the Excluded Ocular Field, alone or with or for Allergan, (ii) the Beam Agreement as to the Excluded Base Editing Non-Cancer Field, or (iii) the BlueRock Agreement as to the BlueRock Field, in each case, as such agreements exist as of the Execution Date and solely for so long as such agreements remain in full force and effect. As used herein, the term “Competing Product” means any product that constitutes, incorporates, comprises or contains any (a) α-β T-Cell or (b) Other Derived T-Cell, in each case, that is modified using any Genome Editing Technology (including any RNP Complex or any component thereof) Directed to any Licensed Program Target for so long as at least one Licensed Program Addendum relating to such Licensed Program Target remains in effect. For the avoidance of doubt, during the Term, any agreement entered into between Editas or any of its Affiliates and a Third Party involving the use of Research, Development, Manufacture, Commercialization or other exploitation activities with respect to any α-β T-Cell, Other Derived T-Cell or any other use of Genome Editing Technology shall expressly exclude the grant of any license, sublicense or other rights, or the conduct of any activities which would violate the terms of this Section 5.1. For clarity, the provisions of this Section 5.1.1 shall not prohibit Editas and its Affiliates, on their own

or through or with any Third Party, from Researching, Developing, Manufacturing, Commercializing or conducting other exploitation activities (including through grants of licenses, sublicenses or other rights to any Third Party to conduct any of the foregoing activities) with respect to its exploitation of Genome Editing Technology, including the use of Licensed RNP Complexes, with respect to any product that is not a Licensed Product or a Competing Product.

5.1.2 Exceptions for Change of Control. Notwithstanding the provisions of Section 5.1.1, if, following the Execution Date, Editas undergoes a Change of Control and an Acquiring Affiliate is engaged in any activities immediately prior to the effective date of such Change of Control that would violate Section 5.1.1 if conducted by Editas (an “Existing Acquirer Program”), then Editas shall not be in breach of the provisions of Section 5.1.1 as a result of the continued conduct of such Existing Acquirer Program by such Acquiring Affiliate during the Term; provided that (a) such Existing Acquirer Program is conducted by such Acquiring Affiliate independently of the activities of this Agreement (including maintaining separate lab notebooks) and without use of, or reference to, any Editas Licensed Background IP, Collaboration IP or any Confidential Information of Juno or any of its Affiliates; (b) no personnel of Editas or any of its Affiliates that are conducting or have conducted any activities under the Research Program or otherwise under this Agreement or the Master Collaboration Agreement, or that has or had access to any Confidential Information of Juno or any of its Affiliates, shall work on the Existing Acquirer Program; and (c) Editas puts in place firewalls and other protections reasonably acceptable to Juno that are reasonably designed to ensure that the foregoing clauses (a) and (b) are complied with during the Term.

5.2 [**]. Notwithstanding anything to the contrary contained herein, during the Term, Editas shall not (and shall cause its Affiliates not to), use any Patent Rights, Know-How or other IP, or any other materials or resources (including any portion of payments from Juno hereunder) that (a) are licensed or otherwise provided by Juno (or any of its Affiliates) hereunder; or (b) were otherwise created, conceived, discovered, generated, invented, made or reduced to practice in the course of conducting any activities pursuant to this Agreement (or the Master Collaboration Agreement), in each case ((a) or (b)) in connection with [**].

5.3 Master Collaboration Agreement. For the avoidance of doubt, the provisions of Section 5.3 of the Master Collaboration Agreement shall not limit in any way the provisions of this ARTICLE 5, and the provisions of this ARTICLE 5 shall not limit in any way the provisions of this Section 5.3 of the Master Collaboration Agreement.

ARTICLE 6

FINANCIAL TERMS

6.1 Opt-In Exercise Fee. Subject to Article 3 of the Master Collaboration Agreement, Juno shall pay to Editas (a) with respect to the Initial Licensed Program, an opt-in exercise fee of [**] Dollars ($[**]) within [**] after the Execution Date; and (b) with respect to each exercise by Juno of its Opt-In Right pursuant to the terms of the Master Collaboration Agreement for a Licensed Program (other than for the Initial Licensed Program), an opt-in exercise fee of [**] Dollars ($[**]) within [**] after the Effective Date of the applicable Licensed Program Addendum (each, an “Opt-In Exercise Fee”).

6.2 Royalties.

6.2.1 Licensed Product Royalties. Subject to the terms of this Section 6.2 (and subject further to Sections 6.4 and 6.7), on a Calendar Year-by-Calendar Year basis, Juno shall pay Editas royalties on Annual Product Net Sales of a given Licensed Product (on a Licensed Product-by-Licensed Product basis) during the applicable Royalty Term for such Licensed Product (provided that the Royalty Term shall be calculated on a Licensed Product-by-Licensed Product and country-by-country basis), equal to the following portions of Annual Product Net Sales of such Licensed Product during a given Calendar Year multiplied by the applicable royalty rate set forth below for such portion of Annual Product Net Sales during the applicable Royalty Term, which royalties shall be paid in accordance with Section 6.2.5. For clarity, the royalties (and royalty tiers) shall be calculated separately on a Licensed Product-by-Licensed Product basis.


Annual Product Net Sales of a Given Licensed Product in a Given Calendar Year	Royalty Rate
Portion of Annual Product Net Sales of a given Licensed Product in a given Calendar Year above $[], up to and including $[]	[**]%
Portion of Annual Product Net Sales of a given Licensed Product in a given Calendar Year above $[], up to and including $[]	[**]%
Portion of Annual Product Net Sales of a given Licensed Product in a given Calendar Year above $[**]	[**]%

The applicable royalty rates set forth in the table above will apply only to that portion of the Annual Product Net Sales of the applicable Licensed Product during a given Calendar Year that falls within the indicated range. For clarity, (a) if no royalty is payable on a given unit of Licensed Product (e.g., following expiration of the Royalty Term for such Licensed Product in a given country), then the Net Sales of such unit of Licensed Product shall not be included for purposes of determining the royalties or royalty tiers; (b) Net Sales of a given Licensed Product will not be combined with Net Sales of any other Licensed Product for purposes of determining the royalties or royalty tiers; and (c) with respect to any Licensed Products for which a royalty is payable, only one royalty shall be payable by Juno to Editas for each sale of a unit of such Licensed Product, regardless of any Licensed Program Addenda subsequently entered into by the Parties. By way of example and without limitation of this Section 6.2.1, if Annual Product Net Sales of a given Licensed Product were $[**] for a given Calendar Year, then the royalties payable with respect to such Annual Product Net Sales for such Licensed Product for such Calendar Year (assuming no further reductions pursuant to Section 6.2.3 or Section 6.2.4), would be: [**].

6.2.2 Royalty Term. Juno’s royalty obligations to Editas under Section 6.2.1 shall apply on a Licensed Product-by-Licensed Product and country-by-country basis only during the applicable Royalty Term for such Licensed Product in such country. Following expiration of the applicable Royalty Term for a given Licensed Product in a given country, as applicable, no further royalties will be payable in respect of sales of such Licensed Product in such country and thereafter

the license granted to Juno hereunder with respect to such Licensed Product in such country will automatically become non-exclusive, fully paid-up, perpetual, irrevocable and royalty-free.

6.2.3 Reductions.

(a) Reductions for No Valid Claim. The royalty amounts payable with respect to Annual Product Net Sales shall be reduced on a Licensed Product-by-Licensed Product and country-by-country basis, to [**] percent ([**]%) of the amounts otherwise payable pursuant to Section 6.2.1 during any portion of the applicable Royalty Term in which the sale of such Licensed Product in such country is not Covered by at least one (1) Valid Claim.

(b) Royalty Reduction for Biosimilar Product. If, on a Licensed Product-by-Licensed Product and country-by-country and Calendar Quarter-by-Calendar Quarter basis:

(i) Biosimilar Product(s) (in the aggregate) have a market share of greater than [**] percent ([**]%) but less than or equal to [**] percent ([**]%); or

(ii) Biosimilar Product(s) (in the aggregate) have a market share of more than [**] percent ([**]%);

then the royalties payable with respect to Annual Product Net Sales of such Licensed Product pursuant to Section 6.2.1 in such country during such Calendar Quarter shall be reduced to [**] percent ([**]%) if subsection (i) applies, or [**] percent ([**]%) if subsection (ii) applies, respectively, of the royalties otherwise payable pursuant to Section 6.2.1. Market share shall be based on the aggregate market in such country of such Licensed Product and the Biosimilar Product(s) (based on the number of units of such Licensed Product and such Biosimilar Product(s) in the aggregate sold in such country, as reported by a well-known reporting service agreed between the Parties acting reasonably (e.g., IQVIA)).

(c) Notwithstanding the foregoing, in the event that (i) the reductions in both Section 6.2.3(a) and Section 6.2.3(b)(i) apply with respect to a Licensed Product in a given country in a given Calendar Quarter or (ii) the reductions in both Section 6.2.3(a) and Section 6.2.3(b)(ii) apply with respect to a Licensed Product in a given country in a given Calendar Quarter, then, in each case ((i) and (ii)), the royalties payable with respect to Annual Product Net Sales of such Licensed Product pursuant to Section 6.2.1 in such country during such Calendar Quarter shall in no event be reduced pursuant to this Section 6.2.3 to less than [**] percent ([**]%) of such royalty payments that would otherwise be payable in such Calendar Quarter.

6.2.4 Royalty Offset for Juno Third Party Payments; Payment of Allocable Costs and Additional Allocable Costs. Subject to Section 7.18, if Juno (or any of its Affiliates or Sublicensees) obtains from a Third Party a right or license under IP of a Third Party (whether prior to or after the applicable Effective Date), where the Research, Development, Manufacturing, Commercialization or other exploitation of a given Licensed Product (or any Licensed RNP Complex or component thereof) by or on behalf of Juno (or any of its Affiliates or Sublicensees), or obtaining the right or license to such IP for use in connection with any of the foregoing, would result in a payment to such Third Party, then Juno may deduct from the royalty payments that

would otherwise have been due to Editas under Section 6.2.1 with respect to Annual Product Net Sales in a particular Calendar Quarter with respect to the applicable Licensed Product, an amount equal to [**] percent ([**]%) of the amount of any royalties or milestone payments actually paid by Juno (or any of its Affiliates or Sublicensees) to such Third Party for such right or license (or the exercise thereof) (“Juno Third Party Payments”); provided that in no event shall the royalty payments due to Editas under Section 6.2.1 (after application of any reductions pursuant to Section 6.2.3) be reduced pursuant to this Section 6.2.4 to less than [**] percent ([**]%) of such royalty payments that would otherwise be payable in such Calendar Quarter; provided, however, that if Juno is unable to fully recover the amounts paid by Juno (or any of its Affiliates or Sublicensees) in such Calendar Quarter, then Juno shall be entitled to carry forward such right of offset to future Calendar Quarters with respect to such excess amount and continue to applying such offset on a Calendar Quarter basis thereafter until fully utilized. Without limiting the foregoing, Juno shall pay to Editas any and all Allocable Costs and Additional Allocable Costs with respect to each Licensed Program (as set forth in the applicable Licensed Program Addendum), and any such Allocable Costs and Additional Allocable Costs shall be deemed Juno Third Party Payments for purposes of this Agreement.

6.2.5 Payment of Royalties. Juno shall: (a) within [**] following the end of each Calendar Quarter in which a royalty payment pursuant to Section 6.2.1 accrues, provide to Editas a written report specifying for such Calendar Quarter (i) the number of Licensed Products sold that are subject to such royalty, (ii) the Annual Product Net Sales in such country during such Calendar Quarter that are subject to such royalty, (iii) the applicable royalty rate under this Agreement, and (iv) any reduction to the royalty applied by Juno pursuant to any one or more of Sections 6.2.3 and 6.2.4; and (b) make the royalty payments owed to Editas hereunder in accordance with such royalty report in arrears, within [**] from the end of the Calendar Quarter in which such payment accrues. In addition, Juno shall use Commercially Reasonable Efforts to, within [**] following a given Calendar Quarter, provide to Editas a preliminary nonbinding report of Annual Product Net Sales of Licensed Product, including gross sales, adjustments made to gross sales and Annual Product Net Sales for such Calendar Quarter.

6.3 Milestones.

6.3.1 Development Milestones.

(a) Subject to the terms of Section 6.3.1(b) (and subject further to Sections 6.4 and 6.7), on a Licensed Product-by-Licensed Product basis, Juno will notify Editas within [**] following the first achievement by Juno or its Affiliates or Sublicensees (provided that if the applicable milestone event is achieved by a Sublicensee, then such notice period shall be extended to [**] following such achievement) under this Agreement after the Effective Date of each milestone event described below in this Section 6.3.1 with respect to a given Licensed Product to achieve such milestone event (each, a “Development Milestone Event”), and Juno shall thereafter pay the applicable amounts set forth below associated with the applicable Development Milestone Event in accordance with Section 6.3.2 (each, a “Development Milestone Payment”):

European Countries for the second Indication (i.e., Juno is relying on the pricing approval for the first Indication in such Major European Countries), the foregoing requirements to obtain separate pricing approvals shall be deemed to have been satisfied

Receipt of Regulatory Approval in Japan issued by the MHLW for a given Licensed Product for a second Indication (which must be a separate and distinct Indication from the first Indication in Development Milestone Event 6 above)

[**] Dollars ($[**])

Each of the foregoing milestones in this Section 6.3.1 shall be payable a maximum of one (1) time for a given Licensed Product as set forth in the foregoing chart achieving the applicable Development Milestone Event (i.e., a maximum of nine (9) Development Milestone Payments may be made pursuant to this Section 6.3.1 for a given Licensed Product), and no Development Milestone Payment shall be due hereunder for subsequent or repeated achievement of such Development Milestone Event.

(b) Notwithstanding the provisions of Section 6.3.1(a), (i) with respect to Development Milestone Events [**], no Development Milestone Payments shall be due or payable hereunder in connection with the achievement of any such Development Milestone Event with respect to any Licensed Product that is not Covered by at least one (1) Valid Claim in the applicable Major Market country of Regulatory Approval triggering such Development Milestone Event as of the date of the achievement of such Development Milestone Event, and (ii) if a given Development Milestone Event was achieved by a given Licensed Product and such Development Milestone Event was subsequently achieved by another Licensed Product that was modified using the same Licensed RNP Complex (alone or as part of a Licensed RNP Complex Group), then no additional Development Milestone Payment shall be due or payable hereunder with respect to such subsequent achievement unless the Licensed Product subsequently achieving such Development Milestone Event contained a Juno Material Modification as compared to any other Licensed Product for which such Development Milestone Event was achieved.

6.3.2 Invoice and Payment of Development Milestone Payments. Following receipt of notification by Juno to Editas that Juno has achieved the applicable milestone event triggering a Development Milestone Payment hereunder, Editas shall invoice Juno for the applicable Development Milestone Payment, and Juno shall pay such Development Milestone Payment within [**] after receipt of the invoice therefor.

6.3.3 Commercial Milestones.

(a) Subject to the terms of Section 6.3.3(b) (and subject further to Section 6.4 and 6.7), Juno will notify Editas within [**] after the end of the Calendar Quarter during which the first achievement by Juno or its Affiliates or Sublicensees under this Agreement

after the Effective Date of a given milestone event described below in this Section 6.3.3 (each, a “Commercial Milestone Event”) with respect to each of the first [**] Licensed Products to achieve such milestone event, and Juno shall thereafter pay the applicable amounts set forth below associated with the applicable milestone event in accordance with Section 6.3.4 (each, a “Commercial Milestone Payment” and together with any Development Milestone Payment, each, a “Milestone Payment”):

Commercial Milestone Event	Commercial Milestone Payment
First achievement of Annual Product U.S. Net Sales of a given Licensed Product in any single Calendar Year exceeding [] Dollars ($[])	[] Dollars ($[])
First achievement of Annual Product U.S. Net Sales of such Licensed Product in any single Calendar Year exceeding [] Dollars ($[])	[] Dollars ($[])
First achievement of Annual Product U.S. Net Sales of such Licensed Product in any single Calendar Year exceeding [] Dollars ($[])	[] Dollars ($[])

Each of the foregoing milestones in this Section 6.3.3 shall be payable a maximum of [**] times, and no Commercial Milestone Payment shall be due hereunder for (i) any subsequent or repeated achievement of such milestone event with respect to the same Licensed Product or (ii) the achievement of any Commercial Milestone Event by additional Licensed Products after [**] Licensed Products have achieved such Commercial Milestone Event. For the avoidance of doubt, the maximum amount payable by Juno pursuant to this Section 6.3.3 is One Hundred Twenty Million Dollars ($120,000,000).

(b) For clarity, (i) if no royalty is payable on a given unit of Licensed Product (e.g., following the Royalty Term for such Licensed Product in a given country), then the Net Sales of such unit of Licensed Product shall not be included for purposes of determining whether a Commercial Milestone Event is achieved and (ii) payment will be due under this Section 6.3.3 with respect to the first [**] Licensed Products to achieve a Commercial Milestone Event, regardless of whether a Commercial Milestone Payment was previously paid with respect such Licensed Product for achievement of an earlier Commercial Milestone Event.

6.3.4 Invoice and Payment of Commercial Milestone Payments. Following receipt of notification by Juno to Editas that Juno has achieved the applicable milestone event triggering a Commercial Milestone Payment hereunder, Editas shall invoice Juno for the applicable Commercial Milestone Payment, and Juno shall pay such Commercial Milestone Payment within [**] after receipt of the invoice therefor.

6.4 Additional Payment Terms.

6.4.1 Payment Method. Except as otherwise provided in other sections of this Agreement, all payments due to a Party hereunder shall be due and payable within [**] after receipt

of an invoice from the other Party and shall be paid via a bank wire or ACH transfer in U.S. dollars to such bank account as such Party shall designate. All dollar amounts specified in this Agreement are U.S. dollar amounts. For clarity, currency transaction rates used by Juno shall be in accordance with its standard accounting practices consistently applied and in accordance with its accounting practices for external reporting purposes. Editas has the right to verify that the exchange rates used by Juno for a given month align with Juno’s external reporting. If the due date of any payment hereunder is not a Business Day, such payment may be paid on the following Business Day. Any undisputed payments that are not paid on the date such payments are due under this Agreement shall bear interest to the extent permitted by Law at the prime rate as reported by The Wall Street Journal on the date such payment is due, plus an additional [**] percent ([**]%), calculated on the number of days such payment is delinquent.

6.4.2 Blocked Currency. If at any time any Law in any country in the Territory makes impossible or illegal the prompt remittance of any payments with respect to sales therein, Juno shall promptly notify Editas of the conditions preventing such transfer and such royalties or other payments shall be deposited in local currency in the relevant country to the credit of Editas in a recognized banking institution with a good creditworthiness, such banking institution to be designated by Editas or, if none is designated by Editas within [**], in a recognized banking institution selected by Juno and identified in a written notice given to Editas. If so deposited in a foreign country, Juno shall provide reasonable cooperation to Editas so as to allow Editas to assume control over such deposit as promptly as practicable.

6.4.3 Confidentiality. Each Party shall treat all financial information of the other Party that is subject to review under this ARTICLE 6 (including all royalty reports) as such other Party’s Confidential Information.

6.4.4 Taxes; Withholding.

(a) Generally. Each Party will pay any and all income taxes levied on account of all payments it receives under this Agreement except as otherwise provided in this Section 6.4.4.

(b) Tax Withholding. Each Party shall be entitled to deduct and withhold from any amounts payable under this Agreement such taxes as are required to be deducted or withheld therefrom under any provision of applicable Law. The Party that is required to make such withholding (the “Paying Party”) will (i) deduct those taxes from such payment, (ii) timely remit the taxes to the proper taxing authority, and (iii) send evidence of the obligation together with proof of tax payment to the other Party (the “Payee Party”) on a timely basis following that tax payment. Each Party agrees to reasonably cooperate with the Paying Party in claiming refunds or exemptions from such deductions or withholdings under any relevant agreement or treaty which is in effect to ensure that any amounts required to be withheld pursuant to this Section 6.4.4(b) are reduced in amount to the fullest extent permitted by applicable Law.

(c) Tax Documentation. Editas has provided a properly completed and duly executed IRS Form W-9 (or other applicable form) to Juno. Prior to the receipt of any payment under this Agreement, Editas (and any other recipient of payments by Juno under this Agreement) shall, to the extent it is legally permitted to, provide to Juno, at the time or times

reasonably requested by Juno or as required by applicable Law, such properly completed and duly executed documentation (for example, IRS Forms W-8 or W-9 or foreign equivalents) as will permit payments made under this Agreement to be made without, or at a reduced rate of, withholding for taxes.

(d) Gross-Up for Increased Taxes. In the event that a withholding tax is imposed at an increased rate on any amount payable under this Agreement solely as a result of (i) any assignment or delegation under Section 12.4 by the paying Party or its predecessor or successor in interest to another Person, (ii) any extension of rights, licenses, immunities and obligations under Section 12.14 by the paying Party or its predecessor or successor in interest to another Person, (iii) the payment of the amount by a Person other than the Party obligated to make such payment under this Agreement, or (iv) any combination of the foregoing clauses (i), (ii) or (iii), in each case ((i) – (iv)), after the applicable Effective Date with a resulting harm to the Party entitled to receive the payment (e.g., the Party entitled to receive the Payment or its Affiliate is not entitled to seek any offsetting credit), then the increase in withholding tax resulting from such action or combination of actions to the extent of such harm (the “Increased Tax”) shall be subject to the provisions of this Section 6.4.4(d). To the extent an Increased Tax is determinable at the time of the associated payment, the amount otherwise payable under this Agreement shall be increased sufficiently that, after payment of all Increased Taxes (including, for the sake of clarity, Increased Tax on any increased payment under this Section 6.4.4(d)) the net amount received by the recipient of the payment is equal to the net amount such recipient would have received in the absence of action or actions resulting in the Increased Tax to the extent of such harm.

6.5 Records Retention by Juno; Review by Editas.

6.5.1 Records. With respect to royalty payments to be made under Sections 6.2 of this Agreement, Juno agrees to keep and shall procure that its Affiliates and Sublicensees keep, for at least [**] from the end of the Calendar Year to which they pertain, complete and accurate records of sales by Juno or any of its Affiliates (including sales by Sublicensees), as the case may be, of each Licensed Product, in sufficient detail to allow the accuracy of such payments made hereunder to be confirmed.

6.5.2 Review. Subject to the other terms of this Section 6.5.2, during the Term, at the request of Editas, which shall not be made more frequently than [**], upon at least [**] prior written notice from Editas, and at the expense of Editas, Juno shall permit an independent, nationally-recognized certified public accountant selected by Editas and reasonably acceptable to Juno to inspect (during regular business hours) the relevant records required to be maintained by Juno under Section 6.5.1; provided that such audit right shall not apply to records beyond [**] from the end of the Calendar Year to which they pertain. In every case, any such accountant must have previously entered into a confidentiality agreement reasonably acceptable to both Parties and limiting the disclosure and use of such information by such accountant to authorized representatives of the Parties and the purposes germane to Section 6.5.1. Results of any such review shall be binding on both Parties absent manifest error. Such accountant shall report to Editas only whether the particular amount being audited was accurate, and if not, the amount of any discrepancy and the basis for such assessment, and such accountant shall not report any other information to Editas. Editas shall treat the results of any such accountant’s review of Juno’s records as Confidential Information of Juno subject to the terms of ARTICLE 8. If any review

reveals a deficiency or overpayment in the calculation or payment of royalties by Juno hereunder, then (a) Juno or Editas, as applicable, shall promptly pay (or refund, as applicable) to the other Party the amount of such deficiency or overpayment, as applicable and (b) in the case of a deficiency, if such deficiency is by more than the greater of (i) [**] percent ([**]%) of the aggregate amounts owed by Juno or (ii) [**] Dollars ($[**]), Juno shall, within [**] after receipt of an invoice therefor, pay the reasonable out-of-pocket costs and expenses incurred by Editas for such independent accountant in connection with the review.

6.5.3 Records Final. Upon the expiration of [**] following the end of a given Calendar Year, subject and without prejudice to the determination of any review commenced prior to such third anniversary pursuant to Section 6.5.2, the calculation of royalties payable with respect to such Calendar Year shall be binding and conclusive upon Editas, and Juno (and its Affiliates) shall be released from any liability or accountability with respect to such royalties for such Calendar Year.

6.6 Editas Third Party Agreements. Notwithstanding anything to the contrary contained herein, Editas shall be solely responsible for all costs and payments of any kind (including all upfront fees, annual payments, milestone payments and royalty payments) arising under any agreements between Editas (or any of its Affiliates) and any Third Party (including under any In-License Agreement or other Existing Program Agreement), which costs or payments arise in connection with, or as a result of, the activities conducted hereunder, including the Research, Development, Manufacture or Commercialization of Licensed RNP Complexes or Licensed Products. Juno shall use Commercially Reasonable Efforts to comply with Editas’ reasonable requests for financial information with respect to its activities hereunder, to the extent reasonably available to Juno, and solely as necessary for Editas to comply with its reporting obligations to any of its In-License Counterparty under the In-License Agreements; provided that Editas shall ensure that each such In-License Counterparty is bound by written confidentiality obligations and non-use obligations no less restrictive than those set forth in ARTICLE 8 to maintain the confidentiality thereof and not to use such information except as expressly permitted by this Agreement; provided, further, that Editas shall remain responsible for any failure by any In-License Counterparty who receives such information to treat information as required under ARTICLE 8.

6.7 Additional Provisions. Notwithstanding anything to the contrary contained herein, the terms and provisions of this ARTICLE 6 are subject to Section 12.7 of the Master Collaboration Agreement and Sections 11.7 and 11.9 of this Agreement.

ARTICLE 7

LICENSES; INTELLECTUAL PROPERTY

7.1 License to Juno. Subject to the terms and conditions of this Agreement, Editas hereby grants to Juno an exclusive (even as to Editas) royalty-bearing right and license, with the right to grant sublicenses (subject to Section 7.4), under the Editas Licensed IP to research (including Research), develop (including Develop), make (including Manufacture), have made (including have Manufactured), use, offer for sale, sell, import, Commercialize and otherwise exploit (a) any Licensed RNP Complex (including any component or variant form thereof) in the Licensed Field in the Territory; and (b) any Licensed Product for any purpose (but excluding the

Excluded Ocular Field and the Excluded Base Editing Non-Cancer Field, in each case, for so long as such field is excluded from the Licensed Field in accordance with Section 1.142) in the Territory. Notwithstanding anything to the contrary contained herein, (i) if the Licensed Program described in a Licensed Program Addendum is Directed to a Co-Exclusive Target (as expressly identified in the Licensed Program Addendum), then the rights sublicensed to Juno under this Section 7.1 with respect to such Co-Exclusive Target shall be co-exclusive with the Third Party holding such rights as described in the Master Collaboration Agreement, but solely with respect to the Editas Licensed Background IP that is the subject of the Harvard-Broad Agreements and for so long as such Third Party has co-exclusive rights thereto, (ii) if the Licensed Program described in a Licensed Program Addendum is Directed to a Target for use in medullary cystic kidney disease 1 (“MCKD1”) (as expressly identified in the Licensed Program Addendum), then the rights sublicensed to Juno under this Section 7.1 with respect to such Licensed Program shall be non-exclusive for use in the MCKD1 field, and (iii) the rights granted pursuant to this Section 7.1 shall be co-exclusive with BlueRock solely to the extent such rights relate to the use of iPSC-derived regulatory T-Cells specifically intended for the treatment, diagnosis or prevention of any Indication that is not a cancer Indication for so long as BlueRock has co-exclusive rights with respect thereto pursuant to the BlueRock Agreement.

7.2 Rights Retained by the Parties. For clarity, each Party retains all rights under Know-How and Patent Rights Controlled by such Party not expressly granted to the other Party pursuant to this Agreement.

7.3 Non-Assertion. Editas hereby covenants and agrees not to (and shall cause its Affiliates not to) xxx or bring any cause of action or otherwise assert against (a) Juno, (b) any Affiliate or Sublicensee of Juno that receives a sublicense or other rights from Juno pursuant to the terms of Section 7.4 or Section 12.14, or (c) any of their respective successors or permitted assigns, for any type of infringement of any Patent Rights or misappropriation of any Know-How (but excluding (i) any Excluded Patents or Excluded Know-How, and (ii) any Subsequently Obtained Licensed IP that Juno has not elected to include pursuant to Section 7.17), which infringement or misappropriation arises from the research (including Research), development (including Development), making (including Manufacture), having made (including having Manufactured), using, offering for sale, selling, importing, Commercializing or otherwise exploiting in accordance with this Agreement (A) any Licensed RNP Complex in the Licensed Field in the Territory; and (B) any Licensed Product for any purpose (but excluding the Excluded Ocular Field and the Excluded Base Editing Non-Cancer Field, in each case, for so long as such field is excluded from the Licensed Field in accordance with Section 1.142) in the Territory.

7.4 Sublicenses. Juno shall have the right to grant sublicenses (including through multiple tiers, subject to limitation(s) on further sublicensing in the In-License Agreement(s) as set forth in Section 7.5, if applicable) under the licenses granted to it under Section 7.1 to its Affiliates or Sublicensees; provided that any sublicense granted under this Agreement to a Sublicensee shall be pursuant to a written agreement that subjects such Sublicensee to all relevant restrictions and limitations set forth in this Agreement and Juno shall notify Editas of each such sublicense granted to a Sublicensee. Juno shall remain responsible for the performance of its Sublicensees, and shall ensure that each Sublicensee complies with the applicable terms and conditions of this Agreement. Notwithstanding the foregoing to the contrary, solely with respect

to Editas Licensed Background IP sublicensed to Juno under the Harvard-Broad Licenses, unless and until the receipt of written agreement by Institutions to permit further sublicensing, Juno shall not have the right to grant any sublicenses (other than to Affiliates of Juno and other than may be agreed in writing by Institutions, in each case subject to all restrictions on the granting of sublicenses herein); provided that at the request of Juno, Editas shall promptly use Commercially Reasonable Efforts to obtain such consent from Institutions. Notwithstanding the foregoing to the contrary, solely with respect to Editas Licensed Background IP sublicensed to Juno under the MGH Licenses, unless and until the receipt of written agreement by MGH to permit further sublicensing, Juno shall not have the right to grant any sublicenses (other than to Affiliates of Juno and other than may be agreed in writing by MGH, in each case subject to all restrictions on the granting of sublicenses herein); provided that at the request of Juno, Editas shall promptly use Commercially Reasonable Efforts to obtain such consent from MGH. All sublicenses granted by Juno hereunder, and any further sublicenses by a Sublicensee shall comply with, and be subject and subordinate to, the relevant terms and conditions of this Agreement. If Editas is unable to obtain the written agreement from the Institutions or MGH, as applicable, within [**] after request by Juno, to allow for the further granting of sublicenses by Juno, then upon Juno’s request at any time during the Term, Editas shall grant a direct license to any Third Party as Juno directs, provided such direct license is within the scope of Juno’s licenses granted under Section 7.1.

7.5 Compliance with In-License Agreements. On a Licensed Program-by-Licensed Program basis, as applicable, the terms of this Agreement, insofar as they relate to a sublicense of Editas Licensed Background IP licensed to Editas or any of its Affiliates pursuant to an In-License Agreement, shall be subject to the applicable provisions of the relevant In-License Agreement, but only to the extent that the applicable In-License Agreement requires such terms and conditions to be imposed on a sublicensee pursuant to such In-License Agreement, as follows: (a) with respect to any Editas Licensed Background IP Controlled by Editas or any of its Affiliates pursuant to the Cas9-I Agreement, the provisions set forth on Schedule 7.5(a) shall apply; (b) with respect to any Editas Licensed Background IP Controlled by Editas or any of its Affiliates pursuant to the Cas9-II Agreement, the provisions set forth on Schedule 7.5(b) shall apply; (c) with respect to Editas Licensed Background IP Controlled by Editas or any of its Affiliates pursuant to the Cpf1 Agreement, the provisions set forth on Schedule 7.5(c) shall apply; (d) with respect to any Editas Licensed Background IP Controlled by Editas or any of its Affiliates pursuant to the 2014 MGH Agreement, the provisions set forth on Schedule 7.5(d) shall apply; and (e) with respect to any Editas Licensed Background IP Controlled by Editas or any of its Affiliates pursuant to the 2016 MGH Agreement, the provisions set forth on Schedule 7.5(e) shall apply; provided that the terms on Schedule 7.5 applicable to a given Licensed Program Addendum shall be appended to such Licensed Program Addendum. Each applicable Licensed Program Addendum shall be updated with respect to any Subsequently Obtained Licensed IP in accordance with Section 7.17.

7.6 No Implied Licenses. Except as explicitly set forth in this Agreement or the Master Collaboration Agreement, neither Party shall be deemed by estoppel or implication to have granted to the other Party any license or other right to any IP or trademarks (or trademark applications) of such Party.

7.7 Insolvency. If this Agreement is terminated due to the rejection of this Agreement by or on behalf of Editas in or during any bankruptcy or similar proceeding of Editas, all licenses

and rights to licenses granted under or pursuant to this Agreement by Editas to Juno are and shall otherwise be deemed to be licenses of rights to “intellectual property” (including for purposes of Section 365(n) of Title 11 of the United States Bankruptcy Code (“Section 365(n)”) and other similar laws in any other jurisdiction). The Parties agree that Juno, as a licensee of such rights under this Agreement, shall retain and may fully exercise all of its rights and elections under any applicable insolvency statute, and that upon (x) commencement of bankruptcy or similar proceeding by or against Editas, (y) any rejection or similar disavowal of this Agreement by Editas in or during any such proceeding and (z) any election by Juno to exercise its rights to continue its licenses hereunder pursuant to Section 365(n) or any similar provision of applicable law in any jurisdiction, Juno shall be entitled to a complete duplicate of or complete access to (as Juno deems appropriate), any such IP and all embodiments of such IP as may be necessary for Juno to enjoy its license rights hereunder. Such IP and all embodiments thereof shall be promptly delivered to Juno following the occurrence of the events described in the foregoing clauses (x) through (z) of this section and upon written request therefor by Juno. The provisions of this Section 7.7 shall be (i) without prejudice to any rights Juno may have arising under any applicable insolvency statute or other applicable Law and (ii) effective only to the extent permitted by applicable Law. For the avoidance of doubt, the payments required to be made by Juno in connection with any exercise of rights under Section 365(n) or any similar provision of applicable law in any jurisdiction shall include both royalties under Section 6.2 hereof and Milestone Payments under Section 6.3 hereof, in each case as such amounts become due and payable and subject to the terms and conditions set forth herein.

7.8 Ownership.

7.8.1 Inventorship. Notwithstanding the provisions of Section 12.1, inventorship of any inventions (whether patentable or not) created, conceived, discovered, developed, generated, invented, made or reduced to practice by or on behalf of a Party or its Affiliates, whether solely or jointly with any Third Party (or with the other Party or its Affiliates), in the course of activities performed under this Agreement, shall be determined by application of U.S. patent law pertaining to inventorship, and, except as otherwise provided for in Sections 7.8.2 and 7.8.3, ownership of IP shall be determined by inventorship.

7.8.2 Editas Licensed Background IP and Editas Licensed Collaboration IP. As between the Parties (including their respective Affiliates), Editas will retain all right, title and interest in and to all Editas Licensed Background IP and Editas Licensed Collaboration IP, except to the extent that any such rights are licensed or granted to Juno under this Agreement or the Master Collaboration Agreement.

7.8.3 Joint IP. The Parties shall each own an equal, undivided interest in (a) any and all Joint Know-How; and (b) any Joint Patents. Each Party shall assign, and hereby assigns, to the other Party, a joint equal and undivided interest in and to such Joint IP (provided, however, that, for clarity, the foregoing joint ownership rights with respect to Joint IP shall not be construed as granting, conveying or creating any license or other rights to any of the other Party’s other IP, unless otherwise expressly set forth in this Agreement), and at the request of a Party, the other Party will execute such documents (including any necessary assignments) to effect such joint ownership of such Joint IP. Each Party shall have the right to disclose (subject to Section 8.1) and exploit (including granting licenses to Third Parties) the Joint IP and Joint Collaboration IP without

a duty of seeking consent or accounting to the other Party; provided that, with respect to Editas, such rights shall be subject to the rights and licenses granted to Juno hereunder (or under the Master Collaboration Agreement), including the obligations of Editas as set forth in ARTICLE 5.

7.8.4 Further Actions. Each Party shall cause its Affiliates and its Affiliates’ employees, consultants, sublicensees, agents and contractors to assign to such Party, such Person’s right, title and interest in and to any and all Editas Licensed Collaboration IP (in the case of Editas) or Joint IP, and IP rights therein, as is necessary to effect the intent of this Section 7.8.

7.9 Patent Liaisons. Promptly after the Execution Date, each Party shall appoint an individual to act as a patent liaison for such Party (each, a “Patent Liaison”). The Patent Liaisons shall be the primary point of contact for the Parties regarding IP-related activities and matters contemplated by this Agreement, as and to the extent requested by Juno from time to time. The name and contact information for each Party’s Patent Liaison, as well as any replacement(s) chosen by such Party, in its sole discretion, from time to time, shall be promptly provided to the other Party in accordance with Section 12.7.

7.10 Prosecution and Maintenance of Editas Licensed Background Patents, Editas Licensed Collaboration Patents, Joint Collaboration Patents and Joint Patents. Following the Effective Date, the provisions of this Section 7.10 shall apply with respect to the Editas Licensed Background Patents, Editas Licensed Collaboration Patents, Joint Collaboration Patents and Joint Patents.

7.10.1 Editas Licensed Background Patents. As between the Parties, Editas shall have the sole right (but not the obligation) to Prosecute and Maintain the Editas Licensed Background Patents; provided, however, that Editas shall use good faith efforts to keep Juno reasonably informed with respect to any material developments regarding the Prosecution and Maintenance of any Editas Licensed Background Patents.

7.10.2 Editas Licensed Collaboration Patents.

(a) Editas shall be responsible for Prosecuting and Maintaining the Editas Licensed Collaboration Patents at Juno’s direction and Juno shall have final decision-making authority with respect thereto. Juno shall reimburse Editas for its reasonable out-of-pocket costs incurred in connection with the Prosecution and Maintenance of such Editas Licensed Collaboration Patents.

(b) If Juno intends to allow an Editas Licensed Collaboration Patent to lapse or become abandoned without having first directed Editas to file a substitute, or decides not to participate in any interferences, reissues, re-examinations, inter partes reviews, derivations, post grant proceedings or oppositions with respect to an Editas Licensed Collaboration Patent it shall notify Editas of such decision or intention at least [**] prior to the date upon which such Patent Rights shall lapse or become abandoned, and, if after such consultation between the Parties, Juno still intends to allow such Editas Licensed Collaboration Patent to lapse or become abandoned, Editas shall thereupon have the right (but not the obligation) to assume the Prosecution and Maintenance thereof at Editas’ expense with counsel of its choice. The foregoing shall not apply where, with reference to a specific patent family, Juno, in its reasonable determination, decides

not to file a continuing application in a particular country due to the existence of one or more pending patent application(s) in such country.

(c) Notwithstanding the foregoing, solely with respect to Editas Licensed Collaboration Patents that are jointly owned by Editas and BlueRock pursuant to the BlueRock Agreement (i.e., BlueRock is a joint inventor on such Patent Right) (the “Editas-BlueRock Joint Patents”), the foregoing prosecution and maintenance rights set forth in this Section 7.10.2 shall be subject to the prosecution and maintenance rights of BlueRock set forth in the BlueRock Agreement for such Editas-BlueRock Joint Patent, as the BlueRock Agreement exists as of the Execution Date and solely for so long as the BlueRock Agreement, or the surviving provisions thereof (to the extent the applicable provisions survive), remains in force and effect.

7.10.3 Joint Collaboration Patents and Joint Patents.

(a) The Parties shall be jointly responsible for Prosecuting and Maintaining the Joint Collaboration Patents and Joint Patents, including for conducting any interferences, re-examinations, inter partes review, post-grant proceedings, reissues and oppositions relating thereto and shall equally share all costs related thereto. The Parties have jointly selected counsel (“Joint Counsel”) for the Prosecution and Maintenance of all Joint Collaboration Patents and Joint Patents. The Joint Counsel shall give Juno and Editas (or each Party’s designee) an opportunity to review the text of each application, office action response or other substantive document relating to a prospective Joint Collaboration Patent or Joint Patent before filing with any patent office in the Territory, shall incorporate Juno’s and Editas’ (or each Party’s designee) reasonable comments with respect thereto, and shall supply Juno and Editas (or each Party’s designee) with a copy of each such application, office action response or other substantive document as filed, together with notice of its filing date and serial number. Both Parties shall cooperate with Joint Counsel for all activities relating to Joint Collaboration Patent or Joint Patent prosecution and maintenance. In the event that Editas and Juno provide Joint Counsel with conflicting instructions regarding the Prosecution and/or Maintenance of a Joint Collaboration Patent or Joint Patent, Juno shall have the final decision-making authority with respect to the Prosecution and Maintenance of such Joint Collaboration Patent or Joint Patent.

(b) If Juno intends to allow a Joint Collaboration Patent or Joint Patent, as applicable, to lapse or become abandoned in any country in the Territory without having first filed a substitute, or decides not to participate in any interferences, reissues, re-examinations, inter partes reviews, derivations, post grant proceedings or oppositions with respect to a Joint Collaboration Patent or Joint Patent, as applicable, it shall notify and consult with Editas of such decision or intention at least [**] prior to the date upon which such Patent Rights shall lapse or become abandoned, and, if after such consultation between the Parties, Juno still intends to allow such Joint Collaboration Patent or Joint Patent, as applicable, to lapse or become abandoned, Editas shall thereupon have the right (but not the obligation) to assume the Prosecution and Maintenance thereof at Editas’ expense with counsel of its choice and under Editas’ direction and control. The foregoing shall not apply where, with reference to a specific patent family, Juno, in its reasonable determination, decides not to file a continuing application in a particular country due to the existence of one or more pending patent application(s) in such country.

7.10.4 Cooperation in Prosecution and Maintenance. The Party that is responsible for the Prosecution and Maintenance of any Editas Licensed Collaboration Patent, Joint Collaboration Patent or Joint Patent, as applicable, pursuant to this Section 7.10 (the “Prosecuting Party”) shall keep the other Party (the “Non-Prosecuting Party”) informed as to material developments with respect to the Prosecution and Maintenance of such Patent Rights including by providing copies of all substantive office actions, examination reports, communications or any other substantive documents to or from any patent office, including notice of all interferences, reissues, re-examinations, inter partes reviews, derivations, post grant proceedings or oppositions. The Prosecuting Party shall also provide the Non-Prosecuting Party with a reasonable opportunity to comment substantively on the Prosecution and Maintenance of such Patent Rights prior to taking material actions (including the filing of initial applications), and will in good faith consider any comments made by and actions recommended by the Non-Prosecuting Party; provided, however, that the Non-Prosecuting Party does so consistent with any applicable filing deadlines. The Non-Prosecuting Party shall reasonably cooperate with the Prosecuting Party in connection with any such actions hereunder, including, where Juno is the Prosecuting Party, by making its employees, agents and consultants reasonably available to the Prosecuting Party (and to the Prosecuting Party’s authorized attorneys, agents or representatives) to enable the Prosecuting Party to undertake such Prosecution and Maintenance. In addition, the Non-Prosecuting Party shall (and shall cause its Affiliates and its and their employees, agents and consultants to) provide reasonable assistance to the Prosecuting Party (and to the Prosecuting Party’s authorized attorneys, agents or representatives) to enable the Prosecuting Party to undertake such Prosecution and Maintenance, including by executing powers of attorney and other documents for the Prosecuting Party to undertake such Prosecution and Maintenance.

7.10.5 Costs of Prosecution and Maintenance. Except as otherwise expressly set forth in this Section 7.10, each Party shall be responsible for all costs and expenses associated with its Prosecution and Maintenance activities under this Section 7.10 with respect to Editas Licensed Background Patents, Editas Licensed Collaboration Patents, Joint Collaboration Patents and Joint Patents that it incurs pursuant to Section 7.10.1, Section 7.10.2 or Section 7.10.3, as applicable. Notwithstanding the foregoing provisions of this Section 7.10.5, Juno will not be responsible for any Prosecution and Maintenance costs associated with any subject matter divided out of such Patent Rights that is not licensed to Juno (and Editas shall reimburse Juno for any such costs incurred by Juno or any of its Affiliates).

7.11 Enforcement of Editas Licensed Background Patents, Editas Licensed Collaboration Patents, Joint Collaboration Patents and Joint Patents.

7.11.1 Notice. If either Party learns of an infringement or threatened infringement by a Third Party in the Territory of any Editas Licensed Background Patent, Editas Licensed Collaboration Patent, Joint Collaboration Patent or Joint Patent, such Party shall promptly notify the other Party and shall provide such other Party with available evidence of such infringement, and following such notification, the Parties shall confer.

7.11.2 Juno Enforcement Rights. Subject to the provisions of this Section 7.11, Juno shall have the sole right, but not the obligation, to institute, prosecute, and control any action or proceeding (which may include settlement or otherwise seeking to secure the abatement of such infringement) with respect to any infringement of (a) any Editas Licensed Collaboration Patent to

the extent such infringement relates to a Competing Product; and (b) Joint Collaboration Patent or Joint Patent, in each case, at Juno’s expense, by counsel of its own choice, in Juno’s own name (or, if required, under Editas’ name) and under Juno’s direction and control, including the right to control the defense of any challenges to such Patent Rights as a counterclaim in such infringement proceeding as well as the defense of declaratory judgment actions; provided, however, that solely with respect to Editas-BlueRock Joint Patents, the foregoing enforcement rights set forth in this Section 7.11.2 shall be subject to the enforcement rights of BlueRock set forth in the BlueRock Agreement for such Editas-BlueRock Joint Patent as the BlueRock Agreement exists as of the Execution Date and solely for so long as the BlueRock Agreement, or the surviving provisions thereof (to the extent the applicable provisions survive), remains in force and effect.

7.11.3 Editas Enforcement Rights. Subject to the provisions of this Section 7.11, as between the Parties, Editas shall have the right (but not the obligation) to institute, prosecute, and control any action or proceeding (which may include settlement or otherwise seeking to secure the abatement of such infringement) with respect to any infringement of (a) any Editas Licensed Background Patent; or (b) any Editas Licensed Collaboration Patent (except to the extent such infringement relates to a Competing Product), in each case, at Editas’ expense, by counsel of its own choice, in Editas’ own name and under Editas’ direction and control, including the right to control the defense of any challenges to such Patent Rights as a counterclaim in such infringement proceeding as well as the defense of declaratory judgment actions. Notwithstanding the foregoing, (i) Editas shall notify Juno in writing prior to initiating any such action or proceeding pursuant to this Section 7.11.3, (ii) Editas shall in good faith give careful consideration of Juno’s views and to potential effects on Juno’s business in making the decision of whether or not to commence such enforcement action; provided that if Juno has any reasonable grounds for believing that Editas’ exercise of its enforcement right with respect to (A) any Editas Licensed Background Patent in connection with a Competing Product or (B) any Editas Licensed Collaboration Patent, in either case, could reasonably be detrimental to the patent protection of any Licensed RNP Complex or Licensed Product, then Editas shall not be permitted to enforce such Patent Rights without the prior consent of Juno, in Juno’s discretion, and (iii) if Juno reasonably requests that Editas exercise its enforcement right with respect to (A) any Editas Licensed Background Patent in connection with a Competing Product or (B) any Editas Licensed Collaboration Patent, in either case, then Editas shall enforce such Patent Rights; provided, however, that if Editas notifies Juno in writing of any reasonable grounds for believing that exercise of such enforcement right with respect to any such Editas Licensed Background Patent could reasonably be detrimental to such Editas Licensed Background Patent, then the Parties shall discuss in good faith and mutually agree on the appropriate enforcement action; provided, further, however, that if Juno requests that Editas exercise its enforcement right with respect to any Editas Licensed Background Patent that is sublicensed to Juno hereunder pursuant to the terms of any In-License Agreement(s) and the terms of such In-License Agreement(s) (as set forth in Section 7.5) restrict the ability of Editas to enforce such Editas Licensed Background Patent, then such enforcement shall be subject to the applicable provisions of Section 7.5.

7.11.4 Joinder. In the case of any enforcement action or proceeding set forth in Section 7.11.2, the non-enforcing Party will (and will cause its Affiliates to) join any such action or proceeding as a party at the enforcing Party’s expense (and the non-enforcing Party will use Commercially Reasonable Efforts to cause any of its Third Party licensors of the applicable Patent

Right 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 or claim damages. The non-enforcing Party may, at its option, participate in such enforcement action or proceeding at its own expense, but the enforcing Party shall still control such action or proceeding. In the case of any enforcement action or proceeding controlled by Editas pursuant to Section 7.11.3, Juno may, at its option, participate in such enforcement action or proceeding at its own expense.

7.11.5 Consultation; Cooperation. The enforcing Party will keep the non-enforcing Party regularly informed of the status and progress of such enforcement efforts with respect to any Editas Licensed Background Patent, Editas Licensed Collaboration Patent, Joint Collaboration Patent or Joint Patent, as applicable. The enforcing Party shall consult with the non-enforcing Party and will take comments of the non-enforcing Party into good faith consideration with respect to the infringement or claim construction of any claim in any such Editas Licensed Background Patent, Editas Licensed Collaboration Patent, Joint Collaboration Patent or Joint Patent, as applicable. The non-enforcing Party will provide the enforcing Party reasonable cooperation in such enforcement, at such enforcing Party’s request and expense.

7.11.6 Settlement. A settlement or consent judgment or other voluntary final disposition of a suit with respect to any Editas Licensed Background Patent, Editas Licensed Collaboration Patent, Joint Collaboration Patent or Joint Patent, as applicable, under this Section 7.11 may be entered into without the consent of the Party not bringing suit; provided, however, that any such settlement, consent judgment or other disposition of any action or proceeding by the Party bringing suit under this Section 7.11 shall not, without the prior written consent of the Party not bringing suit, such consent not to be unreasonably withheld, conditioned or delayed, (a) impose any liability or obligation on the Party not bringing suit or any of its Affiliates; (b) conflict with or reduce the scope of the subject matter claimed in the applicable Editas Licensed Background Patent, Editas Licensed Collaboration Patent, Joint Collaboration Patent or Joint Patent; (c) in the case of Editas as the party bringing the suit, include the grant of any license, covenant or other rights to any Third Party that would conflict with or reduce the scope of the rights or licenses granted to Juno under this Agreement or the Master Collaboration Agreement; or (d) in the case of Editas as the party bringing the suit, otherwise adversely affect the rights granted to Juno hereunder with respect to such Editas Licensed Background Patents, Editas Licensed Collaboration Patents, Joint Collaboration Patents or Joint Patents, as applicable.

7.11.7 Costs and Recoveries. Except as otherwise set forth in this Section 7.11, each Party shall bear all of its costs incurred in connection with its activities under this Section 7.11. Any damages or other monetary awards recovered in any action, suit or proceeding brought under this Section 7.11 to the extent related to any Editas Licensed Background Patents, Editas Licensed Collaboration Patents, Joint Collaboration Patents or Joint Patents shall be shared as follows:

(a) the amount of such recovery actually received by the Party controlling such action shall first be applied to reimburse costs and expenses incurred by each Party in connection with such action (including, for this purpose, a reasonable allocation of expenses of internal counsel); and

(b) the remaining portion of such recovery shall be paid to Juno; provided that Editas shall receive an amount equal to the royalties that would have been due upon such remainder calculated in accordance with Section 6.2 as if such remainder are Net Sales of a Licensed Product sold by or under the authority of Juno; provided that, if the recovery relates to Patent Right(s) that are sublicensed to Juno hereunder pursuant to the terms of any In-License Agreement(s) and the terms of such In-License Agreement(s) (as set forth in Section 7.5), entitles the applicable In-License Counterparty(ies) to a portion of any recovery that is greater than the amount otherwise payable to Editas pursuant to this Section 7.11.7(b), the Parties will meet and agree in good faith on an alternative sharing of such recovery that takes into account the amounts payable to the applicable In-License Counterparty(ies) and results in an equitable allocation of the amounts remaining to Juno and Editas.

7.11.8 Biosimilar Applications. Notwithstanding the foregoing provisions of this Section 7.11, if either Party receives a copy of a Biosimilar Application referencing a Licensed Product, whether or not such notice or copy is provided under any applicable Law (including under the BPCIA, the United States Patient Protection and Affordable Care Act, or their successor provisions, or any similar provisions in a country outside the United States, as applicable), or otherwise becomes aware that such a Biosimilar Application has been submitted to a Regulatory Authority for marketing authorization (such as in an instance described in 42 U.S.C. § 262(l)(2)), the remainder of this Section 7.11.8 shall apply. Such Party shall promptly, but in any event within [**] of becoming aware that such a Biosimilar Application has been submitted to a Regulatory Authority for marketing authorization, notify the other Party. The owner of the relevant Patent Rights shall then seek permission to view the Biosimilar Application, information regarding the process or processes used to manufacture the product that is the subject of the Biosimilar Application, and related confidential information from the filer of the Biosimilar Application if necessary under 42 U.S.C. § 262(l)(1)(B)(iii). If either Party receives any equivalent or similar communication or notice in the United States or any other jurisdiction, the Party receiving such communication or notice shall within [**] notify the other Party of such communication or notice to the extent permitted by applicable Law. Regardless of the Party that is the “reference product sponsor”, as defined in 42 U.S.C. § 262(l)(1)(A), for purposes of such Biosimilar Application:

(a) Juno shall designate, to the extent permitted by applicable Law, or otherwise Editas shall designate in accordance with Juno’s instructions, the outside counsel and in-house counsel who shall receive confidential access to the Biosimilar Application, information regarding the process or processes used to manufacture the product that is the subject of the Biosimilar Application, and any related confidential information pursuant to 42 U.S.C. § 262(l)(1)(B)(ii).

(b) In each case, after consulting with Editas and considering Editas’ comments in good faith, Juno shall have the right to (i) list any Patent Rights, including any Editas Licensed Background Patents, Editas Licensed Collaboration Patents, Joint Collaboration Patents and Joint Patents, as required pursuant to 42 U.S.C. § 262(l)(3)(A) or 42 U.S.C. § 262(l)(7), (ii) respond to any communications with respect to such lists from the filer of the Biosimilar Application, (iii) negotiate with the filer of the Biosimilar Application as to whether to utilize a different mechanism for information exchange other than that specified in 42 U.S.C. § 262(l)(1) and (iv) as to the Patent Rights that will be subject to the litigation procedure as described in 42

U.S.C. § 262(l)(4), decide which Patent Rights shall be selected for litigation under 42 U.S.C. § 262(l)(5)(B)(i)(II), and commence such litigation under 42 U.S.C. § 262(l)(6). If Editas is required pursuant to applicable Law to execute any of these tasks, it shall do so in accordance with Juno’s instructions.

(c) Juno shall have the right, after consulting with Editas, to identify Patent Rights, including any Editas Licensed Background Patents, Editas Licensed Collaboration Patents, Joint Collaboration Patents and Joint Patents, or respond to relevant communications under any equivalent or similar listing to those described in the preceding clause (b) in any other jurisdiction outside of the United States. If Editas is required pursuant to applicable Law to execute any of these tasks, it shall do so in accordance with Juno’s instructions.

(d) Editas shall cooperate with Juno’s reasonable requests in connection with the foregoing activities to the extent required or permitted by applicable Law. Juno shall consult with Editas prior to identifying any Editas Licensed Background Patents, Editas Licensed Collaboration Patents, Joint Collaboration Patents or Joint Patents to a Third Party as contemplated by this Section 7.11.8. Juno shall consider in good faith advice and suggestions with respect thereto received from Editas, and notify Editas of any such lists or communications promptly after they are made.

(e) Each Party shall notify the other Party within [**] after receiving any notice of commercial marketing provided by the filer of a Biosimilar Application pursuant to 42 U.S.C. § 262(l)(8)(A). To the extent permitted by applicable Law, Juno shall have the first right, but not the obligation, to seek an injunction against such commercial marketing as permitted pursuant to 42 U.S.C. § 262(l)(8)(B) and to file an action for infringement. If required pursuant to applicable Law, upon Juno’s request, Editas shall assist in seeking such injunction or filing such infringement action after consulting with Juno. Except as otherwise provided in this Section 7.11.8, any such action shall be subject to the terms and conditions of Sections 7.11.1 through 7.11.7.

(f) The Parties recognize that procedures other than those set forth above in this Section 7.11.8 may apply with respect to Biosimilar Applications, either in the United States or elsewhere. If the Parties determine that certain provisions of applicable Law in the United States or in any other country in the Territory apply to actions taken by the Parties with respect to Biosimilar Applications under this Section 7.11.8 in such country, the Parties shall comply with any such applicable Law in such country (and any relevant and reasonable procedures established by Parties) in exercising their rights and obligations with respect to Biosimilar Applications under this Section 7.11.8 in a manner to effectuate the intent of this Section 7.11.8. Notwithstanding the foregoing provisions of this Section 7.11.8, nothing in this Section 7.11.8 shall grant any rights to Editas with respect to any Juno IP.

7.12 Patent Term Extensions. Subject to the terms of the In-License Agreements as set forth in Section 7.5, Editas shall reasonably cooperate with Juno, including providing reasonable assistance to Juno (including executing any documents as may reasonably be required), in efforts to seek and obtain patent term restoration or supplemental protection certificates or the like or their equivalents in any country in the Territory, where applicable to Editas Licensed Background Patents (excluding any Editas Licensed Background Patents licensed under an In-License

Agreement), Editas Licensed Collaboration Patents, Joint Collaboration Patents or Joint Patents, or any other Patent Rights Controlled by Juno (or any of its Affiliates), including as may be available to the Parties under the provisions of the U.S. Drug Price Competition and Patent Term Restoration Act of 1984 or comparable laws outside the United States, in each case, in connection with any Licensed Product. If elections with respect to obtaining such patent term restoration or supplemental protection certificates or the like or their equivalents are to be made in connection therewith, Juno shall have the right to make the election, and Editas agrees to abide by such election, provided that, with respect to Editas Licensed Collaboration Patents or Editas Licensed Background Patents (excluding any Editas Licensed Background Patents licensed under an In-License Agreement for which Juno shall have no right to make such an election), Juno has (i) given Editas reasonable advance notice of its intention to extend any such Patent Rights; (ii) engaged in good faith discussions with Editas regarding its intention to extend any such Patent Rights and (iii) in good faith considered any argument by Editas to not extend such Patent Rights for business reasons. Without limiting the foregoing, Editas will not (and will cause its Affiliates not to) extend (a) any Editas Licensed Background Patents or Editas Licensed Collaboration Patent, with respect to any Licensed Product or (b) any Joint Collaboration Patent or Joint Patent, in each case ((a) and (b)), without the prior written approval of Juno, in its sole discretion.

7.13 Regulatory Data Protection. Subject to the terms of the In-License Agreements as set forth in Section 7.5, during the Term and after notifying Editas in writing, Juno (or its Designee) shall have the sole right to list, with the applicable Regulatory Authorities in the Territory, all applicable Patent Rights (including any Editas Licensed Background Patents, Editas Licensed Collaboration Patents, Joint Collaboration Patents or Joint Patents) for any Licensed Product, including all so called “Purple Book” listings required under the U.S. Public Health Service Act, and all similar listings in any other relevant countries, and Editas and its Affiliates shall have no right to do so. For the avoidance of doubt, Juno will retain final decision-making authority as to the listing of all applicable Patent Rights for any Licensed Product, regardless of which Party owns such Patent Rights, and Editas shall reasonably assist Juno in connection therewith.

7.14 Common Interest Agreement. At the request of either Party, the Parties shall negotiate in good faith to enter into a common interest agreement to govern their discussion of Patent matters under this Agreement (and the Master Collaboration Agreement).

7.15 License Filing. At the request of Juno, Editas shall, and shall cause its Affiliates to, assist in any license registration processes with applicable Governmental Authorities that may be available for the protection of Juno’s interests in this Agreement.

7.16 Defense of Claims Brought by Third Parties. If a Party becomes aware of any actual or threatened claim that the Research, Development, Manufacture or Commercialization of a Licensed RNP Complex or Licensed Product by or on behalf of Juno pursuant to this Agreement infringes the IP rights of any Third Party, such Party shall promptly notify the other Party. In any such instance, the Parties shall as soon as practicable thereafter meet to discuss in good faith regarding the best response to such notice; provided that Juno shall have the final decision-making authority in connection therewith. Except as set forth in Section 10.2 (and without limiting Juno’s rights under Section 10.2), (a) Juno shall have the sole right, but not the obligation, to defend and dispose of (including through settlement or license) such claim; and (b) any costs incurred by or on behalf of Juno (or any of its Affiliates or Sublicensees) in connection with the defense or

disposal of any such claim (including any damages, royalties or other amounts payable as a result thereof), to the extent relating to the Research, Development, Manufacture or Commercialization of a Licensed RNP Complex or Licensed Product, shall be included as Juno Third Party Payments and may be deducted from amounts payable to Editas hereunder as set forth in Section 6.2.4, and Juno shall report any such deductions to Editas as part of Juno’s royalty report under Section 6.2.5.

7.17 Subsequently Obtained Licensed IP.

7.17.1 In the event that Editas or any of its Affiliates identifies any IP of a Third Party that is necessary for the research, development, making, having made, import, use, offering to sell, selling or otherwise exploiting any Licensed RNP Complex, Licensed Product or Licensed Program Target, then Editas shall notify Juno thereof.

7.17.2 Subject to Section 7.17.1, if, following the Effective Date for a given Licensed Program, Editas or any of its Affiliates (other than an Acquiring Affiliate, unless such Acquiring Affiliate has provided access to Editas or any of its Affiliates to the applicable IP, in which case such Acquiring Affiliate shall be subject to this Section 7.17 with respect to such IP) enters into a license agreement pursuant to which Editas or such Affiliate acquires Control of any IP that claims or covers, or is otherwise necessary or useful for, any Genome Editing Technology, Licensed RNP Complex, Licensed Product or Licensed Program Target with respect to such Licensed Program or the research, development, making, having made, import, use, offering to sell, selling or otherwise exploiting any such Licensed RNP Complex or Licensed Product that was not previously included in the Editas Licensed Background IP (collectively, the “Subsequently Obtained Licensed IP”), Editas shall use Commercially Reasonable Efforts to (a) obtain license terms with respect to such Subsequently Obtained Licensed IP that are not more onerous with respect to any Licensed Programs for which sublicenses are granted to or may be granted to Juno hereunder than they are with respect to any other actual or potential programs or products for which such Subsequently Obtained Licensed IP may be practiced or used; provided that Editas shall in no event disproportionately burden any actual or potential Licensed RNP Complex, Licensed Product or Licensed Program and (b) allow for sublicensing to Juno in accordance with this Agreement. Following execution of the applicable in-license agreement, Editas shall promptly provide to Juno a written description of any applicable Subsequently Obtained Licensed IP, which notice will identify the applicable Licensed Program(s) to which such Subsequently Obtained Licensed IP relates, together with a true, correct and complete copy of any such Third Party license (provided that such copy may be redacted as to terms not applicable to a sublicensee thereunder). On a Licensed Program-by-Licensed Program basis, unless and until any such Subsequently Obtained Licensed IP is sublicensed to Juno in accordance with Section 7.17.3, such Subsequently Obtained Licensed IP shall be deemed not to be Controlled by Editas for purposes of the licenses granted to Juno hereunder.

7.17.3 On a Licensed Program-by-Licensed Program basis, as to any Subsequently Obtained Licensed IP (a) for which Editas has provided notice to Juno pursuant to Section 7.17.1 and (b) under which Editas is permitted to grant sublicense rights to Juno, Juno shall notify Editas in writing, within [**] after the date on which Editas delivers to Juno a copy of the applicable Third Party license agreement pursuant to Section 7.17.1, whether Juno desires to receive a sublicense of rights granted under such Third Party license agreement with respect to such Subsequently Obtained Licensed IP in connection with such Licensed Program and, following

Editas’ receipt of Juno’s notice pursuant to this Section 7.17.3, then the Parties shall in good faith negotiate and mutually agree on (i) any additional terms with respect to such Subsequently Obtained Licensed IP under the applicable Third Party license agreement applicable to Juno as a sublicensees thereunder (“Additional Subsequently Obtained Sublicense Terms”), (ii) Juno’s agreement to reimburse Editas for any royalties actually paid by Editas under such Third Party agreement directly on account of sales of Licensed Products hereunder by Juno, its Affiliates and other sublicensees and (iii) Juno’s reasonable pro rata allocation of any milestone payments actually paid by Editas under such Third Party agreement solely with respect to the sublicense of such Subsequently Obtained Licensed IP as such milestone payments result from the exploitation of the applicable Licensed Product hereunder, which pro rata allocation shall be mutually agreed by the Parties based on the reasonable expected exploitation of such Subsequently Obtained Licensed IP by Juno and its Affiliates and other sublicensees with respect to the applicable Licensed Product in the Licensed Field pursuant to this Agreement as compared to all other current and reasonably anticipated potential products relevant to such Third Party agreement (including Licensed Products and any such products that may be researched, developed or commercialized outside the Licensed Field) ((ii) and (iii), collectively, the “Additional Allocable Costs”); provided that, in all cases, the Parties in determining such Additional Allocable Costs shall take into account all current and reasonably anticipated potential products relevant to such Third Party agreement, including additional Licensed Products and any such products that may be researched, developed or commercialized outside the Licensed Field. In the event that the Parties are unable to agree on any such Additional Subsequently Obtained Sublicense Terms or Additional Allocable Costs pursuant to this Section 7.17.3, the Parties shall escalate the matter to the Executive Officers for resolution, and if the Executive Officers are unable to resolve such issue within [**], the matter shall be resolved by binding arbitration pursuant to Section 12.2.2 (and until such matter is resolved, such Subsequently Obtained Licensed IP shall be deemed not to be Controlled by Editas for purposes of the licenses granted to Juno hereunder). Following determination of the Additional Subsequently Obtained Sublicense Terms and Additional Allocable Costs with respect to any Subsequently Obtained Licensed IP for a given Program in accordance with this Section 7.17.3, Juno may elect to include such Subsequently Obtained Licensed IP for each applicable Licensed Program by providing written notice Editas, in which case, (A) such Third Party license agreement shall be considered an “In-License Agreement” under this Agreement solely with respect to the applicable Licensed Program(s) and such Subsequently Obtained Licensed IP will be deemed to be included in the Editas Licensed Background IP; and (B) the applicable Licensed Program Addendum for each such Licensed Program shall be deemed to be amended to include such Additional Subsequently Obtained Sublicense Terms and Additional Allocable Costs and (C) any Additional Allocable Costs shall be considered Juno Third Party Payments hereunder.

7.18 Juno Continuing Rights Under In-License Agreements. At the written request of Juno on case-by-case basis, Editas shall (or shall cause its Affiliates to, as applicable) execute a written agreement, in a form reasonably acceptable to Juno, with each In-License Counterparty within [**] after the date of such request, pursuant to which (a) in the event of an early termination of such In-License Agreement, at the request of Juno, such In-License Counterparty shall grant a direct license to Juno with respect to the IP licensed to Editas under such In-License Agreement, on the same terms under which such In-License Counterparty grants such license to Editas (or its Affiliate, as applicable) under such In-License Agreement; (b) such In-License Counterparty agrees to and acknowledges the rights granted to Juno hereunder with respect to any IP licensed

to Editas (or its Affiliate, as applicable) under such In-License Agreement, including the rights as set forth in this Section 7.18; and (c) Juno shall be a party to such written agreement and have the right to enforce such agreement directly against the counterparties thereto. Notwithstanding anything to the contrary contained herein (including Section 6.2.4), if Juno (or any of its Affiliates) obtains a license to any Patent Rights, Know-How or other IP (that prior to such license had been included in the Editas Licensed IP) from any In-License Counterparty, then Juno may deduct from any amounts payable by Juno to Editas hereunder (including royalties and milestones), any and all amounts payable by Juno (or any of its Affiliates) to such In-License Counterparty for such right or license (or the exercise thereof).

ARTICLE 8

CONFIDENTIALITY

8.1 Nondisclosure.

ARTICLE 10

INDEMNIFICATION; INSURANCE

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

(a) bodily injury or death resulting from any Licensed Product that during the Term was Researched, Developed, Manufactured, Commercialized, used, sold or otherwise distributed by or on behalf of Juno, its Affiliates or Sublicensees;

(b) the negligence or willful misconduct of Juno or any of its Affiliates or its or their respective directors, officers, employees or agents, in connection with Juno’s performance of its obligations under this Agreement; or

(c) any breach by Juno of any of its representations, warranties, covenants, agreements or obligations under this Agreement;

except, in each case, to the extent such Third Party Damages result from any Third Party Claim covered under Section 10.2(b) or (c).

10.2 Indemnification by Editas. Editas shall indemnify, defend and hold harmless Juno, its Affiliates and its and their respective directors, officers, employees, agents, and their respective successors, heirs and assigns (collectively, the “Juno Indemnitees”), from and against any and all Third Party Damages to the extent arising out of or relating to, directly or indirectly, any Third Party Claim to the extent based upon:

(a) bodily injury or death resulting from (i) any Licensed RNP Complex (or product that was modified using a Licensed RNP Complex) Researched, Developed, Manufactured, Commercialized, used, sold or otherwise distributed by or on behalf of Editas, its Affiliates or sublicensees outside of the Exclusive Field or after the Term or (ii) any activities under the Allergan Agreement, Beam Agreement or BlueRock Agreement;

(b) the negligence or willful misconduct of Editas or any of its Affiliates or its or their respective directors, officers, employees or agents, in connection with the performance of Editas’ obligations under this Agreement; or

(c) any breach by Editas of any of its representations, warranties, covenants, agreements or obligations under this Agreement;

except, in each case, to the extent such Third Party Damages result from any Third Party Claim covered under Section 10.1(b) or (c).

10.3 Procedure. If a Party is seeking indemnification under Section 10.1 or Section 10.2, as applicable (the “Indemnitee”), it shall inform the other Party (the “Indemnitor”) of the claim giving rise to the obligation to indemnify pursuant to Section 10.1 or Section 10.2, as applicable, as soon as reasonably practicable after receiving notice of the claim (provided, however, any delay or failure to provide such notice shall not constitute a waiver or release of, or otherwise limit, the Indemnitee’s rights to indemnification under Section 10.1 or Section 10.2, as applicable, except to the extent that such delay or failure materially prejudices the Indemnitor’s ability to defend against the relevant claims). The Indemnitor shall have the right to assume the defense of any such claim for which the Indemnitee is seeking indemnification pursuant to Section 10.1 or Section 10.2, as applicable. The Indemnitee shall cooperate with the Indemnitor and the Indemnitor’s insurer as the Indemnitor may reasonably request, and at the Indemnitor’s cost and expense. The Indemnitee shall have the right to participate, at its own expense and with counsel of its choice, in the defense of any claim or suit that has been assumed by the Indemnitor. The Indemnitor shall not settle any claim without the prior written consent of the Indemnitee, not to be unreasonably withheld, conditioned or delayed; provided, however, that the Indemnitor shall not be required to obtain such consent if the settlement (a) involves only the payment of money and will not result in the Indemnitee (or other Editas Indemnitees or Juno Indemnitees, as applicable) becoming subject to injunctive or other similar type of relief; (b) does not require an admission by the Indemnitee (or other Editas Indemnitees or Juno Indemnitees, as applicable); and (c) if Editas is the Indemnitor,

does not adversely affect the rights or licenses granted to Juno (or its Affiliate) under this Agreement or the Master Collaboration Agreement. The Indemnitee shall not settle or compromise any such claim without the prior written consent of the Indemnitor, which it may provide in its sole discretion. If the Parties cannot agree as to the application of Section 10.1 or Section 10.2, as applicable, to any claim, pending resolution of the Dispute pursuant to Section 12.2, the Parties may conduct separate defenses of such claims, with each Party retaining the right to claim indemnification from the other Party in accordance with Section 10.1 or Section 10.2, as applicable, upon resolution of the underlying claim. In each case, the Indemnitee shall reasonably cooperate with the Indemnitor, and shall make available to the Indemnitor all pertinent information under the Control of the Indemnitee, which information shall be subject to ARTICLE 8.

10.4 Insurance. During the Term and for a period of [**] thereafter, each Party shall maintain, at its cost, a program of insurance (or, with respect to Juno, self-insurance) against liability and other risks associated with its activities and obligations under this Agreement, and its indemnification obligations hereunder, in such amounts, subject to such deductibles and on such terms as are customary for such Party for the activities to be conducted by it under this Agreement. It is understood that such insurance shall not be construed to create a limit on either Party’s liability with respect to its indemnification obligations under this ARTICLE 10, or otherwise.

10.5 LIMITATION OF LIABILITY. NEITHER EDITAS NOR JUNO, NOR ANY OF THEIR RESPECTIVE AFFILIATES, WILL BE LIABLE TO THE OTHER PARTY OR ITS AFFILIATES UNDER OR IN CONNECTION WITH THIS AGREEMENT FOR ANY INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL OR PUNITIVE OR EXEMPLARY DAMAGES (INCLUDING LOST PROFITS OR LOST REVENUES), WHETHER LIABILITY IS ASSERTED IN CONTRACT, TORT (INCLUDING NEGLIGENCE AND STRICT PRODUCT LIABILITY), INDEMNITY, CONTRIBUTION OR OTHERWISE, 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. NOTWITHSTANDING THE FOREGOING, NOTHING IN THIS SECTION 10.5 IS INTENDED TO OR SHALL LIMIT OR RESTRICT THE INDEMNIFICATION RIGHTS OR OBLIGATIONS OF EITHER PARTY UNDER SECTION 10.1 OR SECTION 10.2 FOR ANY THIRD PARTY DAMAGES OR THE LIABILITY OF EITHER PARTY FOR ANY BREACHES OF ARTICLE 8 OR EDITAS FOR BREACH OF ANY OF ITS OBLIGATIONS UNDER ARTICLE 5.

ARTICLE 11

TERM AND TERMINATION

11.1 Term; Expiration.

11.1.1 Term. This Agreement shall become effective on the Execution Date and, subject to Section 3.5 of the Master Collaboration Agreement as to each such subsequent Licensed Program, on the Effective Date of the applicable Licensed Program Addendum, and, unless earlier terminated in accordance with this ARTICLE 11, shall remain in effect until it expires as follows (the “Term”):

(a) on a Licensed Product-by-Licensed Product and country-by-country basis, this Agreement shall expire on the date of the expiration of the Royalty Term with respect to such Licensed Product in such country; and

(b) in its entirety upon the expiration of all applicable Royalty Terms under this Agreement with respect to all Licensed Products in all countries in the Territory.

11.1.2 Effect of Expiration. After the expiration of the Term pursuant to Section 11.1.1, the following terms shall apply:

(a) Licenses after Licensed Product Expiration. Except with respect to a Licensed Product as to which this Agreement was previously terminated, on a country-by-country basis, after expiration of the Royalty Term with respect to a given Licensed Product in a given country pursuant to Section 11.1.1(a), the licenses set forth in Section 7.1 with respect to such Licensed Product (and the Licensed RNP Complex or Licensed RNP Complex Group, as applicable, used to modify such Licensed Product) in such country will automatically become non-exclusive, fully paid-up, perpetual, irrevocable and royalty-free.

(b) Licenses after Expiration of this Agreement. Except with respect to a Licensed Product as to which this Agreement was previously terminated, after expiration of the Term with respect to this Agreement in its entirety pursuant to Section 11.1.1(b), all licenses set forth in Section 7.1 will automatically become non-exclusive, fully paid-up, perpetual, irrevocable and royalty-free.

11.2 Termination for Breach.

11.2.1 Material Breach.

(a) Licensed Product-by-Licensed Product. This Agreement may be terminated, on a Licensed Product-by-Licensed Product basis, by a Party for the material breach by the other Party of this Agreement with respect to such Licensed Program; provided that the breaching Party has not cured such breach within sixty (60) days after the date of written notice to the breaching Party of such breach (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. For clarity, but subject to Section 11.2.2, the Cure Period for any allegation made as to a material breach under this Agreement 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 under this Section 11.2.1(a) shall become effective at the end of the Cure Period, unless the breaching Party has cured such breach prior to the expiration of such Cure Period, or, if such breach is not susceptible to cure within the Cure Period, then such Cure Period shall be extended for an additional sixty (60) days so long as such material breach is susceptible to cure within such extension period and the breaching Party continues to use commercially reasonable efforts to cure such material breach during such extension period. This Agreement shall remain in force and effect with respect to any and all other Licensed Products that were not subject to the foregoing termination.

(b) Licensed Program-by-Licensed Program. On a Licensed Program-by-Licensed Program basis, in the event that Juno fails to make any undisputed payment owed to Editas hereunder with respect to a Licensed Product from a given Licensed Program, Editas may terminate this Agreement as to such Licensed Program, including all Licensed Products from such Licensed Program; provided that Editas has provided Juno with a written notice of breach with respect to such non-payment and Juno not cured such non-payment within the Cure Period. For clarity, but subject to Section 11.2.2, the Cure Period for any allegation made as to such breach under this Agreement will run from the date that written notice was first provided to Juno by Editas. Any such termination of this Agreement under this Section 11.2.1(b) shall result in termination of the relevant Licensed Program Addenda and become effective at the end of the Cure Period, unless Juno has cured such non-payment prior to the expiration of such Cure Period. This Agreement shall remain in force and effect with respect to any and all other Licensed Programs that were not subject to the foregoing termination.

11.2.2 Disagreement as to Breach. Notwithstanding Section 11.2.1, if the Parties in good faith disagree as to whether there has been a breach of this Agreement pursuant to Section 11.2.1, then: (a) the Party that disputes that there has been a breach may contest the allegation by referring such matter, within [**] following such written notice of alleged breach, 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 breach has occurred pursuant to Section 11.2.1; provided that if the Executive Officers are unable to resolve such dispute within such [**] period after it is referred to them, the matter will be resolved as provided in Section 12.2; (b) the relevant Cure Period with respect thereto will be tolled from the date the breaching Party notifies the non-breaching Party of such dispute and through the resolution of such dispute in accordance with the applicable provisions of this Agreement; (c) subject to Section 11.9, during the pendency of 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 (d) if it is ultimately determined that the breaching Party committed such breach, then the breaching Party shall have the right to cure such breach, after such determination, within the Cure Period (as may be extended in accordance with Section 11.2.1) which shall commence as of the date of such determination. Notwithstanding the foregoing, the applicable dispute resolution terms of Section 7.5 shall apply with respect to termination rights solely with respect to any IP Controlled by Editas under the Harvard-Broad Licenses.

11.3 Voluntary Termination. Juno may terminate this Agreement at will, in its sole discretion, on a Licensed Product-by-Licensed Product basis or in its entirety upon ninety (90) days’ prior written notice to Editas at any time.

11.4 Termination for Bankruptcy. To the extent allowed under Law, either Party shall have the right to terminate this Agreement in the event of the commencement of any proceeding in or for bankruptcy, insolvency, dissolution or winding up by or against the other Party (other than pursuant to a corporate restructuring) that is not dismissed or otherwise disposed of within [**] thereafter.

11.5 Termination for Patent Challenge. In the event that Juno (or its Affiliate or Sublicensee) brings a Patent Challenge against an Editas Licensed Background Patent or Editas Licensed Collaboration Patent or knowingly assists another party in a Patent Challenge against an

Editas Licensed Background Patent or Editas Licensed Collaboration Patent, except as required under a court order or subpoena or where Juno (or its Affiliate or Sublicensee) is required by legal process to be joined as a party to the Patent Challenge proceeding, Editas shall have the option to terminate this Agreement at its sole discretion with respect to such Editas Licensed Background Patent(s) or Editas Licensed Collaboration Patent(s), as applicable, that are subject of the Patent Challenge upon [**] written notice to Juno if such Patent Challenge or assistance, as applicable, is not dropped by Juno within such [**] period; provided that Editas shall not have the right to terminate this Agreement with respect to the applicable Editas Licensed Background Patent(s) or Editas Licensed Collaboration Patent(s), as applicable, under this Section 11.5, with respect to any such Patent Challenge by a Sublicensee if Juno terminates the sublicense granted to such Sublicensee with respect to the challenged Editas Licensed Background Patent(s) or Editas Licensed Collaboration Patent(s), as applicable, within [**] of Editas’ notice to Juno under this Section 11.5. Notwithstanding the foregoing, the applicable terms of Section 7.5 shall apply with respect to any Patent Challenge brought by Juno against Patent Rights Controlled by Editas under the Harvard-Broad Licenses.

11.6 Effects of Termination.

11.6.1 Termination in Full. In the event of termination of this Agreement in its entirety for any reason:

(d) notwithstanding the foregoing provisions of this Section 11.6, the licenses granted to Juno hereunder shall survive for twelve (12) months following the effective date of termination in order for Juno (and its Affiliates, Sublicensees and Distributors), at Juno’s discretion, during the twelve (12)-month period immediately following the effective date of termination, to (i) finish or otherwise wind-down any ongoing Clinical Trials with respect to any Licensed Products hereunder; and (ii) finish and sell any work-in-progress and any Licensed Products remaining in inventory; provided that Juno shall pay royalties on Annual Product Net Sales of such Licensed Products sold by Juno during such period, to the extent during the applicable Royalty Term, as and to the extent Juno would otherwise be required to pay such royalties as set forth in Section 6.2; provided, however, that Juno shall have no obligation to undertake such activities, in each case of (i) and (ii), as and to the extent determined by Juno.

11.7 Certain Additional Remedies of Juno in Lieu of Termination. If Juno has the right to terminate this Agreement (with respect to a given Licensed Product(s)) pursuant to Section 11.2, then in lieu of Juno terminating pursuant to Section 11.2, Juno may elect to have this Agreement continue in full force and effect as modified by this Section 11.7 by providing written notice to Editas prior to the date that otherwise would have been the effective date of termination had Juno exercised its right to so terminate this Agreement (with respect to a given Licensed Product(s)) under Section 11.2; provided that (a) Juno has provided notice to Editas asserting the alleged breach as required by Section 11.2, (b) Editas fails to cure such breach prior to the expiration of the applicable Cure Period (provided that if Editas has notified Juno that it disputes that it is in material breach in accordance with Section 11.2.2, then the Cure Period shall be tolled during the pendency of such dispute as set forth in Section 11.2.2). In such an event, Juno may elect to have this Agreement continue in full force and effect by providing written notice to Editas; provided, however, that if Juno so elects to continue this Agreement, then from and after such time as Juno delivers such written notice to Editas, any and all amounts thereafter payable by Juno hereunder (including Milestone Payments and royalties) shall be reduced by [**] percent ([**]%).

11.8 Surviving Provisions.

11.8.1 Accrued Rights; Remedies. Termination or expiration of this Agreement for any reason shall be without prejudice to any rights that shall have accrued to the benefit of any Party prior to such termination or expiration, and any and all damages or remedies (whether in law or in equity) arising from any breach hereunder, each of which shall survive termination or expiration of this Agreement. Such termination or expiration shall not relieve any Party from obligations, which are expressly indicated to survive termination or expiration of this Agreement. Any payment obligations of a Party that have accrued as of termination or expiration of this Agreement shall survive such termination or expiration, as applicable. Except as otherwise expressly set forth in this Agreement, the termination provisions of this ARTICLE 11 are in addition to any other relief and remedies available to either Party under this Agreement and at applicable Law.

ARTICLE 12

MISCELLANEOUS

12.1 Governing Laws; Venue; Jurisdiction. This Agreement shall be governed by, interpreted and enforced in accordance with the laws of the State of New York, without regard to principles of conflicts or choice of laws that would cause the application of the laws of another jurisdiction and excluding the United Nations Convention on Contracts for the International Sales of Goods; provided, however, that with respect to matters involving the validity or infringement of Patent Rights in a given country, such matter may be brought in the applicable country and the applicable Laws of the applicable country shall apply (subject to Section 7.8.1). Subject to Section 12.2, Disputes arising out of this Agreement shall be subject to the exclusive jurisdiction and venue of the state and federal courts located in New York, New York (and the appellate courts thereof), and each Party hereby irrevocably consents to the personal and exclusive jurisdiction and venue thereof.

12.2 Disputes.

12.2.1 General. Except as otherwise expressly set forth in this Agreement, if any dispute, claim or controversy of arising out of or relating to this Agreement, including any action or claim based on tort, contract or statute, or concerning the interpretation, effect, termination validity, performance or breach of this Agreement (each, a “Dispute”), arises between the Parties and the Parties cannot resolve such dispute within [**] of a written request by either Party to the other Party, the Parties agree to refer the Dispute to the respective Executive Officers of each Party for resolution; provided that decisions that are subject to the decision-making authority of a given Party, as expressly set forth in this Agreement, will not be subject to the provisions of Section 12.2 so long as such decisions are made in accordance with this Agreement.

12.2.2 Arbitration. If, after an additional [**], such representatives have not succeeded in negotiating a resolution of the Dispute, and a Party wishes to begin an arbitration to resolve such Dispute arising under this Agreement, such Party shall provide written notice (the “Arbitration Request”) to the other Party of such intention and a statement of the issues for resolution. From the date of the Arbitration Request and until such time as such Dispute has become finally settled, the running of the time periods as to which Party must cure a breach of this Agreement becomes suspended as to any breach that is the subject matter of the Dispute. Within [**] after the receipt of the Arbitration Request, the other Party may, by written notice, add additional issues for resolution in a statement of counter-issues.

12.2.3 Arbitration Procedure. Any arbitration pursuant to this Section 12.2 will be held in New York, New York, United States unless another location is mutually agreed by the Parties. The arbitration will be governed by the United States Arbitration Act, 9 U.S.C. §§ 1-16, to the exclusion of any inconsistent state Law. The Parties shall mutually agree on the rules to govern discovery and the rules of evidence for the arbitration within [**] after the Arbitration Request. If the Parties fail to timely agree to such rules, the United States Federal Rules of Civil Procedure will govern discovery and the United States Federal Rules of Evidence will govern evidence for the arbitration. The arbitration will be conducted by a single arbitrator knowledgeable in the subject matter at issue in the dispute and acceptable to both Parties; provided that the Parties may by mutual agreement elect to have the arbitration conducted by a panel of three (3) arbitrators.

If the Parties fail to agree on a mutually acceptable arbitrator within [**] after the Arbitration Request, then the arbitrator shall be selected by the New York, New York office of the American Arbitration Association. The arbitrator may proceed to an award, notwithstanding the failure of either Party to participate in the proceedings. The arbitrator shall, within [**] after the conclusion of the arbitration hearing, issue a written award and statement of decision describing the essential findings and conclusions on which the award is based, including the calculation of any damages awarded. The arbitrator shall be limited in the scope of his or her authority to resolving only the specific matter which the Parties have referred to arbitration for resolution and shall not have authority to render any decision or award on any other issues. Subject to Section 10.5, the arbitrator shall be authorized to award compensatory damages, but shall not be authorized to award punitive, special, consequential, or any other similar form of damages, or to reform, modify or materially change this Agreement. The arbitrator also shall be authorized to grant any temporary, preliminary or permanent equitable remedy or relief the arbitrator deems just and equitable and within the scope of this Agreement, including an injunction or order for specific performance. The award of the arbitrator shall be the sole and exclusive remedy of the Parties, except for those remedies that are set forth in this Agreement or which apply to a Party by operation of the applicable provisions of this Agreement, and the Parties hereby expressly agree to waive the right to appeal from the decisions of the arbitrator, and there shall be no appeal to any court or other authority (government or private) from the decision of the arbitrator. Judgment on the award rendered by the arbitrator may be enforced in any court having competent jurisdiction thereof.

12.2.4 Arbitration Costs. Each Party shall bear its own attorneys’ fees, costs, and disbursements arising out of the arbitration, and shall pay an equal share of the fees and costs of the arbitrator; provided, however, that the arbitrator, in his or her award, shall be authorized to determine whether a Party is the prevailing Party, and if so, to award to that prevailing Party reimbursement for its reasonable attorneys’ fees, costs and disbursements (including, for example, expert witness fees and expenses, transcripts, photocopy charges and travel expenses).

12.2.5 Confidentiality. All proceedings and decisions of the arbitrator shall be deemed Confidential Information of each of the Parties, and shall be subject to ARTICLE 8.

12.2.6 Equitable Relief; Cumulative Remedies. Notwithstanding anything to the contrary contained herein, including Section 12.2.2, either Party may, without waiving any remedy under this Agreement, seek from any court having jurisdiction equitable relief, including any injunctive or provisional relief and specific performance to protect the rights or property of that Party. Such remedies will not be deemed to be the exclusive remedies for a breach of this Agreement but will be in addition to all other remedies available at law or equity. In addition, notwithstanding the provisions of Section 12.2.2, either Party may bring an action in any court having jurisdiction to enforce an award rendered pursuant to Section 12.2.2. The Parties further agree not to raise as a defense or objection to the request or granting of such relief that any breach of this Agreement is or would be compensable by an award of money damages. No remedy referred to in this Agreement is intended to be exclusive, but each shall be cumulative and in addition to any other remedy referred to in this Agreement or otherwise available under applicable Law.

12.2.7 Pending Final Resolution. Until final resolution of the Dispute in accordance with this Agreement, (a) this Agreement will remain in full force and effect; and (b)

the time periods for cure as to any termination will be tolled. The Parties further agree that any payments made pursuant to this Agreement pending resolution of the dispute shall be refunded if a final determination is made in accordance with this Agreement that such payments are not due.

12.2.8 WAIVER OF JURY TRIAL. EXCEPT AS LIMITED BY APPLICABLE LAW, EACH PARTY HERETO HEREBY IRREVOCABLY WAIVES ALL RIGHT TO TRIAL BY JURY IN ANY ACTION, PROCEEDING OR COUNTERCLAIM (WHETHER BASED IN CONTRACT, TORT OR OTHERWISE) ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE ACTIONS OF EITHER PARTY HERETO IN THE NEGOTIATION, ADMINISTRATION, PERFORMANCE AND ENFORCEMENT HEREOF.

12.3 Independent Contractors. The relationship of the Parties under this Agreement is that of independent contractors. Nothing contained herein is intended or is to be construed so as to constitute (a) Editas as a partner, agent, or joint venturer of Juno; or (b) Juno as a partner, agent or joint venturer of Editas. Neither Editas nor Juno, respectively, shall have any express or implied right or authority to assume or create any obligations on behalf of or in the name of Juno or Editas, respectively, or to bind Juno or Editas, respectively, to any contract, agreement, or undertaking with any Third Party.

12.4 Assignment.

12.4.1 General. The Parties agree that, except as expressly permitted hereunder, neither this Agreement nor their rights and obligations under this Agreement shall be delegated, assigned or otherwise transferred to a third party, in whole or part, whether voluntarily or by operation of law, including by way of sale of assets, merger or consolidation, without prior written consent of the other Party. Notwithstanding the foregoing, a Party may, without such consent, assign this Agreement and its rights and obligations hereunder in their entirety (a) to an Affiliate (provided, however, that such Party will remain fully and unconditionally liable and responsible to the other Party for the performance and observance of all such duties and obligations by such Affiliate), provided that, upon written request by the other Party, such Party will disclose to the other Party whether it has assigned this Agreement to an Affiliate and, in such case, the identity of such Affiliate, or (b) its successor in interest in connection with its merger, consolidation, or sale of all or substantially all of its assets or that portion of its business pertaining to the subject matter of this Agreement. Subject to the foregoing, this Agreement shall be binding on and inure to the benefit of the Parties and their permitted successors and assigns. Any attempted delegation, assignment or transfer in violation of this Section 12.4 shall be null and void ab initio.

12.4.2 Additional Restrictions for Institution In-Licenses. Without limiting the foregoing, Juno agrees that the rights granted under this Agreement pursuant to the Harvard-Broad Licenses may not be assigned by Juno, whether by operation of law or otherwise, without the consent of the Institutions, except that Juno may assign or transfer this Agreement without the consent of the Institutions, to a successor in interest of all or substantially all of Juno’s assets or business related to the Licensed Products or this Agreement, whether by merger, consolidation, sale of assets, or Change of Control or other transaction, provided that (a) Juno shall provide the Institutions with a written notice of such assignment or Change of Control including the identity of the assignee, transferee or controlling party, and a copy of the assignment and assumption agreement or other documentary evidence sufficient to demonstrate Juno’s compliance with this

Section 12.4.2 within [**] after such assignment or Change of Control, and (b) such assignee or transferee agrees in writing to assume the obligations to the Institutions and HHMI that are being assigned or transferred. Failure of an assignee to agree to be bound by the terms hereof or failure of Juno to notify Institutions and provide copies of assignment documentation as specified above shall be grounds for termination of Juno’s sublicense under the applicable Harvard-Broad License(s) with respect to Juno’s rights under the applicable Editas Licensed Background Patent(s) that are the subject of such Harvard-Broad License(s).

12.4.3 Additional Restrictions for MGH In-Licenses. Juno may assign or transfer the rights granted under this Agreement to Juno pursuant to the MGH License: (a) without the consent of MGH, to an Affiliate of Juno or in connection with the transfer or sale of all or substantially all of Juno’s assets or business related to the Licensed Products and/or this Agreement, whether by merger, consolidation, sale of assets, change in control or other transaction, provided that Juno promptly shall provide MGH with a written notice of such assignment including the identity of the assignee or transferee and such assignee or transferee agrees in writing to assume the obligations to MGH that are being assigned or transferred; and (b) in any other circumstance, only with the prior written consent of MGH, such consent not to be unreasonably withheld, conditioned or delayed. Juno shall notify MGH in writing of any such assignment and provide a copy of the assignment and assumption agreement or other documentary evidence sufficient to demonstrate Juno’s compliance with this Section 12.4.3 within [**] after such assignment. Failure of an assignee to agree to be bound by the terms hereof or failure of Juno to notify MGH and provide copies of assignment documentation shall be grounds for termination of Juno’s sublicense under the MGH License with respect to Juno’s rights under the applicable Editas Licensed Background Patent(s) that are the subject of the MGH License.

12.4.4 Assignment to Xxxxxxx-Xxxxx Squibb. Editas hereby represents and warrants that, as of the Execution Date, it has notified each of the Institutions and MGH of the pending merger between Xxxxxxx-Xxxxx Squibb Company (or its affiliate) and Celgene Corporation (or its affiliate), and no further consents on the part of the Institutions or MGH, and no further actions on the part of Juno or its successors, are required under the Harvard-Broad Licenses or the MGH Licenses in connection with any assignment of this Agreement as a result thereof; provided that within [**] after the effective date of such merger, Juno shall provide a signed notice with respect thereto to the Institutions and MGH.

12.5 Force Majeure. A Party shall not be liable for delay or failure in the performance of any of its obligations hereunder if such delay or failure is due to a cause beyond the reasonable control of such Party, including acts of God, fires, earthquakes, acts of war, terrorism, or civil unrest, or hurricane or other inclement weather (“Force Majeure”); provided, however, that the affected Party promptly notifies the other Party; provided, further, that the affected Party shall use its commercially reasonable efforts to avoid or remove such causes of non-performance and to mitigate the effect of such occurrence, and shall continue performance in accordance with the terms of this Agreement whenever such causes are removed. When such circumstances arise, the Parties shall negotiate in good faith any modifications of the terms of this Agreement that may be necessary or appropriate in order to arrive at an equitable solution.

12.6 Right to Develop Independently. Except as otherwise expressly set forth in this Agreement, including ARTICLE 5, nothing in this Agreement shall impair either Party’s right to

independently acquire, license, develop for itself, or have others develop for it, IP and technology performing similar functions as the other Party’s IP or to market and distribute products or services based on such other IP and technology.

12.7 Notices. Any notice required or permitted to be given by this Agreement shall be in writing and in English and shall be (a) delivered by hand or by overnight courier with tracking capabilities; (b) mailed postage prepaid by first class, registered, or certified mail; or (c) delivered by facsimile followed by delivery via either of the methods set forth in Section 12.7(a) or (b), in each case, addressed as set forth below unless changed by notice so given:

12.8 Interpretation.

12.8.1 Generally. This Agreement has been diligently reviewed by and negotiated by and among the Parties, and in such negotiations each of the Parties has been represented by competent (in house or external) counsel, and the final agreement contained herein, including the language whereby it has been expressed, represents the joint efforts of the Parties and their counsel. Accordingly, in interpreting this Agreement or any provision hereof, no presumption shall apply against either Party as being responsible for the wording or drafting of this Agreement or any such provision, and ambiguities, if any, in this Agreement shall not be construed against either Party, irrespective of which Party may be deemed to have authored the ambiguous provision.

12.8.2 Definitions; Interpretation. The definitions of the terms herein shall apply equally to the singular and plural forms of the terms defined and where a word or phrase is defined herein, each of its other grammatical forms shall have a corresponding meaning. Whenever the context may require, any pronoun shall include the corresponding masculine, feminine, and neuter forms. Any capitalized term used but not otherwise defined herein shall have the meaning ascribed to such term in the Master Collaboration Agreement. The word “will” shall be construed to have the same meaning and effect as the word “shall”. The words “including”, “includes”, “include”, “for example” and “e.g.” and words of similar import will be deemed to be followed by the words “without limitation”. The word “or” shall be construed as the inclusive meaning identified with the phrase “and/or”. The words “hereof”, “herein” and “herewith” and words of similar import shall, unless otherwise stated, be construed to refer to this Agreement as a whole and not to any particular provision of this Agreement. Unless the context requires otherwise or as otherwise specifically provided, (a) all references herein to Articles, Sections, Schedules or Exhibits shall be construed to refer to Articles, Sections, Schedules and Exhibits of this Agreement and (b) reference in any Section to any subclauses are references to such subclauses of such Section.

12.8.3 Subsequent Events. Unless the context requires otherwise, (a) any definition of or reference to any agreement, instrument, or other document herein shall be construed as referring to such agreement, instrument, or other document as from time to time amended, supplemented, or otherwise modified (subject to any restrictions on such amendments, supplements, or modifications set forth herein); (b) any reference to any applicable Law herein shall be construed as referring to such applicable Law as from time to time enacted, repealed, or amended; and (c) any reference herein to any Person shall be construed to include the Person’s successors and assigns (subject to Section 12.4).

12.8.4 Headings. Headings, captions and the table of contents are for convenience only and are not to be used in the interpretation of this Agreement.

12.8.5 Independent Significance. Although the same or 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 separately, be given independent significance and not be construed as limiting any other provision of this Agreement (whether or not more general or more specific in scope, substance or content).

12.9 Further Assurances. At any time or from time to time on and after the date of this Agreement, a Party shall at the written and reasonable request of the requesting Party: (a) deliver to the requesting Party such records, data or other documents consistent with the provisions of this Agreement; (b) execute, and deliver or cause to be delivered, all such consents, documents or further instruments of transfer or license; and (c) take or cause to be taken all such ministerial actions, as the requesting Party may reasonably deem necessary or desirable in order for the requesting Party to obtain the full benefits of this Agreement and the transactions contemplated hereby.

12.10 Severability. If any provision, or portion thereof, in this Agreement is held by a court of competent jurisdiction to be void, invalid or unenforceable to any extent, 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 solely for such situation and solely in such jurisdiction, unless the invalid, void 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, void or unenforceable term or provision. If the final judgment of such court 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, void 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.

12.11 Waiver. Any waiver, modification, release or amendment of any obligation under or of any provision of this Agreement or of a Party’s rights or remedies under this Agreement must be in writing to be effective. Failure, neglect, or delay by a Party to enforce the provisions of this Agreement or its rights or remedies at any time, shall not be construed as a waiver of such Party’s rights under this Agreement and shall not in any way affect the validity of the whole or any part of this Agreement or prejudice such Party’s right to take subsequent action. No exercise or enforcement by either Party of any right or remedy under this Agreement shall preclude the enforcement by such Party of any other right or remedy under this Agreement or that such Party is entitled by Law to enforce.

12.12 Entire Agreement; Modification. This Agreement, together with the attached exhibits (including any and all Licensed Program Addendum) and schedules, and the Master Collaboration Agreement, as well as any amendments hereto or thereto made in accordance with the terms hereof or thereof, constitutes the entire understanding and agreement between the Parties with respect to the subject matter hereof and supersedes any and all prior and contemporaneous negotiations, representations, agreements, and understandings, written or oral, that the Parties may have reached with respect to the subject matter hereof. Except as otherwise expressly set forth herein this Agreement may not be altered, amended or modified in any way except by a writing (excluding email or similar electronic transmissions) signed by the authorized representatives of both Parties. In the event of a conflict between the provisions of this Agreement, the provisions

of the Master Collaboration Agreement, this Agreement shall control with respect to each Licensed Program, Licensed Program Target, Licensed RNP Complex and Licensed Product.

12.13 No Third Party Beneficiaries. Except as expressly set forth in this Agreement, there are no Third Party beneficiaries hereunder and the provisions of this Agreement are for the exclusive benefit of the Parties, and no other person or entity shall have any right or claim against either Party by reason of these provisions or be entitled to enforce any of these provisions against either Party.

12.14 Extension to Affiliates. Juno shall have the right to extend the rights, licenses, immunities and obligations granted in this Agreement to one or more of its Affiliates. All applicable terms and provisions of this Agreement shall apply to any such Affiliate to which this Agreement has been extended to the same extent as such terms and provisions apply to Juno. Juno shall remain fully liable for any acts or omissions of such Affiliates and for such Affiliates’ performance and observance of all duties and obligations under this Agreement.

12.15 Counterparts. This Agreement may be executed in two or more counterparts, each of which shall be deemed an original, but all of which together shall constitute one and the same instrument. Any such counterpart, to the extent delivered by means of a fax machine or by .pdf, .tif, .gif, .jpeg or similar attachment to electronic mail (any such delivery, an “Electronic Delivery”) shall be treated in all 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 defense to the formation of a contract, and each Party forever waives any such defense, except to the extent that such defense relates to lack of authenticity.

ARTICLE 13

13.1 Indemnification under the Harvard-Broad Licenses. Notwithstanding the provisions of ARTICLE 10 to the contrary, the provisions of this Section 13.1 shall apply to Juno’s obligation to indemnify Institution Indemnitees, MGH Indemnitees, MIT Indemnitees and HHMI Indemnitees:

13.1.1 Juno shall, and shall cause its Affiliates and Sublicensees to, indemnify, defend and hold harmless the Institution Indemnitees and MIT Indemnitees from and against any claim, suit, investigation, action, demand, judgment, liability, cost, expense, damage, deficiency, loss or obligation of any kind or nature (including reasonable attorneys’ fees and other costs and expenses of litigation or defense), based upon, arising out of, or otherwise relating to Juno’s or its Affiliates’ or Designees’ activities under this Agreement or any sublicense or subcontract by Juno hereunder, including any cause of action relating to product liability concerning any product, process, or service made, used, sold or performed by Juno its Affiliates or Designees pursuant to any right or license granted under this Agreement (collectively, “Claims”) except to the extent any such Claim results from or arises out of the gross negligence or willful misconduct of an Institution Indemnitee or MIT Indemnitee seeking indemnification hereunder or material breach of the

applicable Harvard-Broad License by an Institution. Juno and each of its Affiliates and Sublicensees are referred to as “Juno Indemnitor” below.

13.1.2 Notification of Editas; Editas Right to Consent. In the event that a Juno Indemnitor receives notice of any Claim for which indemnification may be sought hereunder, Juno shall promptly, but no longer than [**] later, notify Editas of such Claim and as soon as reasonably practicable thereafter provide Editas with all documentation and information Juno Indemnitor may have in its possession with regard thereto. Neither Juno, nor any of its Affiliates or Sublicensees, may settle such Claim on terms that admit any liability on the part of Editas, impose any obligation on Editas, or diminish the rights of Editas without Editas’ prior written consent, which may be given or withheld in Editas’ sole discretion.

13.1.3 Procedures. With respect to any Claim for which indemnification is sought by an Institution Indemnitee or MIT Indemnitee pursuant to Section 13.1.1, Juno acknowledges and agrees that the provisions of such Harvard-Broad License (as in effect as of the Execution Date) relating to the procedures for indemnification shall apply as if such procedures were written in full herein, with the defined terms “Company” being deemed to refer to Juno, “Indemnitor” being deemed to refer to Juno and each of its Affiliates and Sublicensees and “Indemnitees” being deemed to refer to Institution Indemnitees and MIT Indemnitees.

The previous sentence shall not apply to any Claim that is determined with finality by a court of competent jurisdiction to result solely from the gross negligence or willful misconduct of an HHMI Indemnitee. Notwithstanding any other provision of this Agreement, Juno’s obligation to defend, indemnify and hold harmless the HHMI Indemnitees under this paragraph shall not be subject to any limitation or exclusion of liability or damages or otherwise limited in any way.

13.1.5 MGH Indemnity. Juno shall indemnify, defend and hold harmless MGH Indemnitees against any Claim, except to the extent any such Claim results directly from the gross negligence or willful misconduct of an MGH Indemnitee. With respect to any Claim for which indemnification is sought by an MGH Indemnitee pursuant to this Section 13.1.5, Juno acknowledges and agrees that the provisions of such MGH License (as in effect as of the Execution Date) relating to the procedures for indemnification shall apply as if such procedures were written in full herein, with the defined terms “Company” being deemed to refer to Juno, “Hospital” being deemed to refer to MGH and “Indemnitee(s)” being deemed to refer to MGH Indemnitee(s).

13.1.6 Notwithstanding the foregoing provisions of this Section 13.1, (a) the Juno Indemnitors shall have no obligations to defend, indemnify or hold harmless any Institution Indemnitees, MGH Indemnitees, MIT Indemnitees and HHMI Indemnitees, if any Juno Indemnitors would have a claim for indemnification from Editas pursuant to Section 10.2 (in which case Editas shall be responsible for defending, indemnifying and holding harmless any Institution Indemnitees, MGH Indemnitees, MIT Indemnitees and HHMI Indemnitees, and the Juno Indemnitors shall be entitled to seek indemnification in accordance with Section 10.2) and (b) the provisions of Section 10.5 shall apply.

13.2 Use of Names. Except as provided in this Section 13.2, Juno shall not, and shall ensure that its Affiliates and Sublicensees shall not, use or register the name “The Broad Institute, Inc.,” “Xxxx Institute for Biologically Inspired Engineering at Harvard University,” “President and Fellows of Harvard College,” “Massachusetts Institute of Technology,” “Lincoln Laboratory,” “The Rockefeller University,” “University of Tokyo,” “TODAI TLO, Ltd.,” “Wageningen University,” “Wageningen University & Research,” “University of Iowa Research Foundation,” “University of Iowa,” “The General Hospital Corporation,” “Massachusetts General Hospital,” “MGH,” [**] “GenEdit,” or any variation, adaptation, or abbreviation thereof (alone or as part of another name) or any logos, seals, insignia or other words, names, symbols or devices that identify such Persons or any of such Persons’ schools, units, divisions or affiliates or any trustee, director, officer, staff member, employee, student or other agent of such Person (“Institution Names”) for any purpose in connection with this Agreement, except as required by applicable Law or otherwise with the prior written approval of, and in accordance with restrictions required by, such Person. Juno further agrees, except as required by applicable Law or as otherwise provided below in this Section 13.2, not to use any Institution Names for any purpose in connection with this Agreement except with the prior written approval of, and in accordance with the restrictions required by, the applicable counterparty. Without limiting the foregoing, Juno shall, and shall ensure that its Affiliates and Sublicensees shall cease all use of Institution Names in connection with this Agreement as permitted under this Agreement on the termination or expiration of this Agreement except as required by applicable Law or otherwise approved in writing by the applicable counterparty, as applicable.
