Period, for Baxalta to designate combinations of [***] Included Targets to be a single Included Target (each such combination, a “Combination Target”); provided, however, that
(a) a combination of Targets may not be designated as a Combination Target unless (i) [***] the Targets within such combination are also Included Targets on an individual basis, and (ii) each of such Included Targets is not itself a
Combination Target, and (b) a Combination Target shall constitute a separate Included Target for all purposes under this Agreement, except that a Combination Target shall not constitute a separate Included Target for purposes of Baxalta’s
limit of designating up to six (6) Included Targets. 
 2.1.2 Initial Included Target. The Parties agree that B-lymphocyte
antigen CD19 (“CD19”) is hereby designated, as of the Effective Date, as the initial Included Target. A summary draft Development Plan for CD19 is attached hereto as Exhibit G. No later than [***] days after the Effective Date,
Precision shall deliver to Baxalta a full Development Plan for CD19, [***]. As promptly as practicable thereafter (but in no event later than [***] after delivery of such proposed Development Plan), the JSC shall meet to review and approve such
Development Plan. The Parties will work together in good faith to ensure that the Development Plan for CD19 has been approved by the JSC by no later than [***] after Precision’s delivery of the full Development Plan for CD19. 

2.1.3 Unavailable Targets. 

(a) Precision represents and warrants that as of the Effective Date, there are no Unavailable Targets. Except as expressly set forth in this
Section 2.1.3, Baxalta shall have no rights with respect to any Unavailable Targets, and Precision and its Affiliates may freely undertake and engage in, including in collaboration with Third Parties, any research,
Development, Commercialization or any other activities of any kind in any field with respect to all Unavailable Targets without any obligation to Baxalta. For clarity, without limiting the obligations set forth in
Section 2.4, nothing in this Agreement shall be construed to preclude, limit, restrict or otherwise affect any right or ability of Precision or any of its Affiliates to enter into any agreement that would cause any Target
that is not an Included Target to become an Unavailable Target at any time. 
 (b) If any Target becomes an Unavailable Target after the
Effective Date, Precision shall submit a complete and accurate list of Unavailable Targets along with a copy of the applicable agreement related to each of such Unavailable Targets, which copies may be submitted in redacted form except to the extent
necessary to confirm that such agreement relates to any Development and/or Commercialization of products with respect to such Unavailable Target (the “Unavailable Target Information”), to an independent escrow agent mutually agreed
to by the Parties (the “Escrow Agent”), and shall provide the Escrow Agent with updated Unavailable Target Information promptly upon any Target becoming an Unavailable Target or losing its status as an Unavailable Target. The
Unavailable Target Information shall be held by the Escrow Agent in confidence. If Precision notifies Baxalta that any Target is an Unavailable Target, the Escrow Agent shall provide confirmation to Baxalta that such Target is an Unavailable Target.
The Escrow Agent shall not provide to Baxalta the identity of any other Target that appears on the list of Unavailable Targets or any details regarding any agreement related to any Unavailable Target. Precision represents and warrants that the
Unavailable Target Information maintained with the Escrow Agent shall be promptly updated by Precision in order to remain accurate, complete and up-to-date at all times
during the Nomination Period. 
 2.1.4 Nomination of Additional Targets. At any time during the Nomination Period, Baxalta may
designate up to (i) [***] additional Targets that are not Unavailable Targets or Precision Targets, or (ii) subject to Section 2.1.1, any number of Combination Targets, as Included Targets in accordance with this
Section 2.1.4. Baxalta may Nominate a Target for potential designation as an Included Target by providing Precision with written notice identifying the Target and providing such other information (if any) that it determines
may be reasonably

necessary or useful to Precision for preparing the associated Development Plans (the “Target Information Package”). If Baxalta Nominates pursuant to any provision of this
Agreement any Target that is an Unavailable Target as of the date of Nomination by Baxalta, Precision shall promptly, but in no event more than [***] following Nomination, provide Baxalta with written notice that such Target is an Unavailable
Target, and shall request confirmation by the Escrow Agent in accordance with Section 2.1.3(b), and such Nomination by Baxalta shall have no further effect. If Baxalta Nominates pursuant to any provision of this Agreement
any Target that is a Precision Target as of the date of Nomination by Baxalta, such Nomination by Baxalta shall have no effect. If the Nominated Target is not an Unavailable Target or a Precision Target as of the date of Nomination by Baxalta,
Baxalta and Precision will meet to discuss the Target Information Package through a meeting of the JSC, including any technical or other concerns Precision may have with respect to any such Target. Provided that Baxalta desires to move forward with
Nomination after such meeting, Precision shall prepare and deliver to the JSC within [***] after the date of such meeting (i) a proposed Development Plan for such Target for review and approval by the JSC, and (ii) a list of Variants that
Precision believes in good faith are capable of being generated by Precision via Precision Platform Technology for such Target (the date such proposal and Variant list are delivered, the “Target Proposal Date”). A Target will be
deemed an Included Target if (and only if) (x) Baxalta has selected at least one (1) Variant to be the subject of a Development Plan and (y) the Development Plan for such Variant(s) and Target has been approved in writing by the JSC;
in each case within [***] after the Target Proposal Date (or any extended period as mutually agreed by the Parties). If Baxalta does not move forward with Nomination or select one or more Variants, or if the JSC does not approve the proposed
Development Plan for at least one of the Variants proposed by Precision and selected by Baxalta, the Parties shall discuss same at the following JSC meeting. For the avoidance of doubt, if any Target Nominated by Baxalta, other than any Unavailable
Target or Precision Target, fails to become an Included Target through the foregoing process, Baxalta may later re-Nominate such Target, but such Target will not be an Included Target unless the process
described in this Section 2.1.4 has been repeated resulting in such Target becoming an Included Target. 
 2.1.5
Additional Variants for Included Targets. 
 (a) Proposal of Additional Variants. From time to time during the Term, Precision
may notify Baxalta in writing of one or more additional Variants (which may include Unselected Candidates) that Precision believes in good faith are capable of being generated by Precision via Precision Platform Technology for an Included Target
(the date such notice is provided, the “Candidate Proposal Date”). If, within [***] after such notification, Baxalta indicates in writing that it is interested in reviewing a proposed Development Plan for such Variant(s), then
Precision will prepare a proposed Development Plan that includes such Variant(s) for review and approval by the JSC within [***] after receipt of such indication of interest from Baxalta. Each proposed Variant will be deemed a Licensed Product
Candidate for such Included Target if (and only if) a Development Plan that includes such Variant has been approved in writing by the JSC,

which approval shall be provided within [***] after the Candidate Proposal Date (or any extended period as mutually agreed by the Parties). If (a) Baxalta does not indicate that it is
interested in reviewing a proposed Development Plan for any one or more of such Variants within the applicable time period above or (b) the JSC does not approve a Development Plan for any one or more of such Variants within the applicable time
period above, such Variants shall thereafter be (or continue to be, as applicable) deemed Unselected Candidates. 
 (b) Final Proposal of
Additional Variants. During any period in which (i) Baxalta does not hold a Commercial License for any one or more Licensed Products Directed to a particular Included Target, and (ii) there is no Licensed Product Candidate Directed to
such Included Target that is currently the subject of Development activities under a Development Plan pursuant to Section 2.2, this Section 2.1.5(b) shall apply with respect to proposals of
additional Variants for such Included Target in lieu of Section 2.1.5(a). During any such period with respect to a particular Included Target, Precision may notify Baxalta of one or more additional Variants (which may
include Unselected Candidates) that Precision believes in good faith are capable of being generated by Precision via Precision Platform Technology for such Included Target and if Baxalta indicates in writing that it is interested in reviewing a
proposed Development Plan for such Variant(s), which it must do within [***] after the date of Precision’s notice, Precision shall promptly deliver a proposed Development Plan that includes such Variant(s) for review and approval by the JSC
(the later of the expiration of such [***] period or the date such Development Plan(s) are provided, the “Final Candidate Proposal Date”). Each proposed Variant will be deemed a Licensed Product Candidate for such Included Target if
(and only if) a Development Plan that includes such Variant has been approved in writing by the JSC, which approval shall be provided within [***] after the Final Candidate Proposal Date (or any extended period as mutually agreed by the Parties). If
the JSC does not approve a Development Plan for any one or more of such Variants within such time period above, or if Baxalta does not express interest in any such Variants within the [***] period set forth above, then notwithstanding anything to
the contrary in this Agreement, Baxalta shall be deemed to have terminated this Agreement with respect to such Included Target (including all Licensed Product Candidates, Unselected Candidates, and Variants Directed to such Included Target) pursuant
to Section 14.2.5. 
 2.1.6 Extension of the Nomination Period. Baxalta may (in its sole discretion)
request to extend the Nomination Period for a single additional term of [***] by providing written notice of such request to Precision; provided, however, that such extension shall only become effective upon mutual written agreement of the Parties
(in the Parties’ sole discretion) regarding funding commitments and other terms related to such extension. For clarity, while the Parties will be obligated to discuss the proposed extension in good faith, neither Party shall be obligated to
agree to extend the Nomination Period.

 2.2 Development Plans; Development Obligations. 

2.2.1 Precision shall, subject to the oversight of the JSC, use Commercially Reasonable Efforts to direct, coordinate, perform and manage the
Development of Licensed Product Candidates for each of the Included Targets, in each case in accordance with this Agreement and the applicable Development Plan. 

2.2.2 Through the JSC, each Party shall have the right to propose changes to the Development Plans on an ongoing basis as necessary. The JSC
shall have the authority to review and approve such changes, provided that each Development Plan shall at all times contain terms that are consistent with this Article II. If the terms of any Development Plan contradict, or create
inconsistencies or ambiguities with, the terms of this Agreement, then the terms of this Agreement shall govern. 
 2.2.3 Precision shall be
solely responsible for, shall use Commercially Reasonable Efforts to carry out, and shall pay all costs and expenses incurred by Precision in carrying out, Development activities for each Licensed Product Candidate in accordance with the applicable
Development Plan (including any fees and associated costs and expenses for Regulatory Filings to be made by Precision pursuant to the Development Plans). Precision may not subcontract any of Precision’s Development obligations (other than to a
CMO approved pursuant to Section 6.2) without the JSC’s consent to the subcontracting of such obligations (but which shall not require the JSC’s consent to any particular subcontractors that are not contract
research organizations that will conduct Clinical Trials under this Agreement or CMOs), and, if the JSC provides such consent, Precision agrees that any subcontractor (including any contract research organization or CMO) shall be bound by written
obligations consistent with those required under Section 11.1.1(a) and written obligations of confidentiality and non-use consistent with this Agreement, and such other provisions to
permit Precision to comply with all the terms and conditions of this Agreement. Precision shall remain responsible for compliance with this Agreement and shall be fully responsible for any breach of this Agreement by any of its subcontractors. 

2.2.4 Promptly, but in no event more than [***], following receipt of trial phase data for the first Phase I Clinical Trial dose escalation
study with respect to any Licensed Product Candidate, Precision shall deliver written notice to the JSC, together with a copy of the relevant data regarding the results of such study (the “Phase I Notice”). The JSC shall promptly
(but in any event within [***] after the Phase I Notice) convene a meeting to review and discuss such data with respect to such Licensed Product Candidate and determine (a) whether activities related to the manufacture of Phase II Clinical
Trial material for such Licensed Product Candidate should be initiated under the applicable Development Plan, and (b) the amount of such material that will be sufficient to conduct the initial Phase II Clinical Trial with respect to such
Licensed Product Candidate. If the JSC does not determine to initiate such activities, then the JSC shall meet to consider whether it is commercially reasonable to continue to seek to achieve Phase II

Ready Status for such Licensed Product Candidate and, upon a positive determination, develop a plan for such achievement. If the JSC determines that it is not commercially reasonable to continue
to seek to achieve Phase II Ready Status for such Licensed Product Candidate, or fails to approve a plan for such achievement within [***] after such meeting of the JSC, then neither Party shall be required nor permitted to conduct any further
Development or Commercialization activities under this Agreement with respect to such Licensed Product Candidate. 
 2.2.5 Promptly, but in
no event more than [***] following the achievement of Phase II Ready Status (which may or may not include, for purposes of Precision’s notice as set forth in this sentence, the JSC having identified a pivotal Phase II Clinical Trial dose for
the applicable Licensed Product Candidate) with respect to any Licensed Product Candidate, Precision shall deliver written notice to the JSC (the “Development Achievement Notice”), together with a copy of the data package regarding
the results of Precision’s research and development program for such Licensed Product Candidate. The JSC shall promptly, but in no event more than [***] following receipt of such notice, convene a meeting to review and discuss such notice and
data package with respect to such Licensed Product Candidate and, if not yet identified by the JSC, to identify a pivotal Phase II Clinical Trial dose for such Licensed Product Candidate. Additionally, for [***] following the end of such meeting,
Baxalta may request, and Precision shall thereafter provide as promptly as practicable, any additional information that could reasonably be expected to assist Baxalta in determining whether it desires to exercise the Commercial Option for the
applicable Licensed Product Candidate in accordance with Section 4.1. If the JSC determines that the Development Achievement Notice was not properly provided, or that it cannot identify a pivotal Phase II Clinical Trial
dose for the applicable Licensed Product Candidate based on the available Phase I Clinical Trial data, then the Development Achievement Notice shall be deemed not to have been delivered by Precision. In the event that the JSC determines that it
cannot identify a pivotal Phase II Clinical Trial dose for the applicable Licensed Product Candidate based on the available Phase I Clinical Trial data, (a) the JSC shall meet to consider whether it is commercially reasonable to continue to
seek to achieve Phase II Ready Status for such Licensed Product Candidate and, upon a positive determination, develop a plan for such achievement and (b) if the JSC determines that it is not commercially reasonable to continue to seek to
achieve Phase II Ready Status for such Licensed Product Candidate, or fails to approve a plan for such achievement within [***] after such meeting of the JSC, then neither Party shall be required nor permitted to conduct any further Development or
Commercialization activities under this Agreement with respect to such Licensed Product Candidate. 
 2.2.6 Following the Commercial Option
Exercise Date for each Licensed Product Candidate, Baxalta shall be solely responsible for and shall have sole control of, and shall use Commercially Reasonable Efforts to carry out, all further Development activities for such Licensed Product in
the Territory, at Baxalta’s sole cost and expense (including any fees and associated costs and expenses for Regulatory Filings made following such exercise). With respect to determinations by Baxalta to discontinue Development activities for a
particular Licensed Product in all countries throughout the Territory, Baxalta shall give Precision written notice of such determination within a reasonable period of time, but in any event within [***] after any such determination is made, and upon
provision of such notice Baxalta shall be deemed to have terminated this Agreement pursuant to Section 14.2.5 with respect to such Licensed Product.

activities conducted under the Development Plan will be successful or that any particular results will be achieved. 
 2.3 Development of
Unselected Candidates. 
 2.3.1 Precision and its Affiliates shall be free to Develop Unselected Candidates (but not any other Variant
for an Included Target that is not a Licensed Product Candidate) at their own expense, provided that (a) Precision complies with its obligations under the Development Plans, (b) no Unselected Candidate may be the subject of any Clinical
Trial unless approved in advance by the JSC, and (c) no Unselected Candidate may be the subject of Development efforts conducted in collaboration with or on behalf of any Third Party without prior approval of the JSC. Precision will deliver
written updates to Baxalta no less frequently than quarterly regarding the status of Precision’s Development of any Unselected Candidates, including all reasonably necessary data to allow Baxalta to assess Precision’s progress towards
achieving a functional CAR-T Directed to the applicable Included Target with any Unselected Candidate, including details regarding the first in-vivo proof of concept and
pre-IND information relating to each such Unselected Candidate. If any Unselected Candidate is approved by the JSC for Clinical Trials, Precision shall provide no less than [***] advance written notice prior
to any planned IND filing with respect to such Unselected Candidate. If safety concerns related to the Unselected Candidates arise from such Development activities, Precision must inform Baxalta immediately. Any publication or presentation with
respect to Unselected Candidates shall be subject to Section 12.3. 
 2.3.2 Baxalta may elect to designate any
Unselected Candidate as a Licensed Product Candidate for a particular Included Target at any time until the [***] anniversary of the date upon which such Included Target became an Included Target, by notifying Precision in writing that it is
interested in reviewing a proposed Development Plan for such Unselected Candidate. In such event, Precision will prepare a proposed Development Plan for such Unselected Candidate for review and approval by the JSC within [***] after receipt of such
indication of interest from Baxalta. The Unselected Candidate will be deemed a Licensed Product Candidate for such Included Target if (and only if) a Development Plan for such Unselected Candidate has been approved in writing by the JSC, which
approval shall be provided within [***] after such written indication of interest from Baxalta (or any extended period as mutually agreed by the Parties). If such Unselected Candidate becomes a Licensed Product Candidate, and if such Unselected
Candidate has previously achieved any Development Milestone(s) [***] prior to

2.3.3 For the avoidance of doubt, the rights set forth in this Section 2.3 shall be subject to Precision’s
obligations under the Precision Restrictive Covenants. 
 2.4 Inactive Targets; Precision Targets. 

2.4.1 Inactive Targets. From the Effective Date until the end of the Nomination Period, Precision shall notify Baxalta in writing prior
to Precision initiating Development of any CAR-T Directed to any Target that is clinically relevant to oncology and not an Included Target, Unavailable Target or Precision Target (each, an “Inactive
Target”); provided that, the JSC must determine that a Target (other than an Unavailable Target or Precision Target) is not clinically relevant to oncology prior to Precision being relieved of any obligations with respect to such Target
pursuant to this Section 2.4. For clarity, Precision and its Affiliates may freely undertake and engage in, including in collaboration with Third Parties, any research, Development, Commercialization or any other activities
of any kind in any field with respect to Inactive Targets at their own expense without any obligation to Baxalta except as expressly set forth in this Section 2.4. 

2.4.2 Nomination of Inactive Targets. At any time during the Nomination Period, Baxalta may Nominate any Inactive Target. In such
event, the process set forth in Section 2.1.4 shall commence with respect to the Nomination of such Inactive Target. If an Inactive Target becomes an Included Target as a result of such process, such Inactive Target shall
thereafter cease to be an Inactive Target and shall be deemed to be an Included Target, and if any Variant for such Inactive Target has previously achieved any Development Milestone(s) [***] prior to becoming a Licensed Product Candidate, Precision
may immediately invoice Baxalta for such achieved Development Milestone(s), and Baxalta shall make the applicable payment within [***] following receipt of such invoice. If such Inactive Target fails to become an Included Target as a result of such
process, then such Inactive Target shall continue to be an Inactive Target, subject to the terms of this Agreement. 
 2.4.3 Updates;
Inactive Target Non-Disclosure Period. 
 (a) During the Nomination Period, Precision will
deliver written updates to Baxalta no less frequently than Calendar Quarterly regarding the status of Precision’s Development of any Inactive Targets that are clinically relevant to oncology, including all reasonably necessary data to allow

 (b) Precision will not provide any Inactive Target Evaluation Data to any Third Party in
connection with any discussions with or inquiries of a Third Party that, at the time such data would be provided, relate to a transaction that would result in such Inactive Target becoming an Unavailable Target during the Nomination Period, unless
Precision has first provided notice to Baxalta of its desire to share such information with such a Third Party, together with a proposed Development Plan and list of Variants that Precision believes in good faith are capable of being generated by
Precision via Precision Platform Technology for such Inactive Target, and Baxalta has had at least [***] after such notice and delivery of a proposed Development Plan and list of Variants (the “Inactive Target
Non-Disclosure Period”) to determine whether Baxalta desires to Nominate such Inactive Target as an Included Target in accordance with this Agreement. 

(c) If Baxalta provides notice Nominating an Inactive Target within the applicable Inactive Target
Non-Disclosure Period (which it may do only if it has a bona fide interest in such Inactive Target becoming an Included Target), then the following shall apply with respect to such Nomination in lieu of
Section 2.4.2. Such Inactive Target shall be deemed an Included Target if (and only if) (i) Baxalta has selected at least one such Variant to be the subject of the Development Plan for such Inactive Target and
(ii) an initial Development Plan including such Variant as a Licensed Product Candidate for such Inactive Target has been approved in writing by the JSC; in each case within the Inactive Target
Non-Disclosure Period (or any extended period as mutually agreed by the Parties). If such Inactive Target becomes an Included Target as a result of such process, such Inactive Target shall thereafter cease to
be an Inactive Target and shall be deemed to be an Included Target, and if any Variant for such Inactive Target has previously achieved any Development Milestone(s) [***] prior to becoming a Licensed Product Candidate, Precision may immediately
invoice Baxalta for such achieved Development Milestone(s), and Baxalta shall make the applicable payment within [***] following receipt of such invoice. 

(d) If, prior to the expiration of the applicable Inactive Target Non-Disclosure Period for an
Inactive Target, Baxalta does not Nominate such Inactive Target as set forth in Section 2.4.3(c), or if Baxalta Nominates such Inactive Target during the applicable Inactive Target
Non-Disclosure Period and such Inactive Target fails to become an Included Target as the result of the process described above, then Precision and its Affiliates shall thereafter be free to share the
applicable Inactive Target Evaluation Data for such Inactive Target with any Third Party for a period of [***] directly following the conclusion of the Inactive Target Non-Disclosure Period for such Inactive
Target (such [***] period, the “Inactive Target Freeze Period”). During the Inactive Target Freeze Period, (i) Precision’s obligation to share the applicable Inactive Target Evaluation Data with Baxalta under
Section 2.4.3(a) with respect to such Inactive Target shall not apply, and (ii) Baxalta shall have no right to Nominate such Inactive Target. Following the conclusion of the Inactive Target Freeze Period, unless such
Inactive Target has become an Unavailable Target during such period, Precision’s obligations with respect to such Inactive Target under Section 2.4.3(a) shall resume (including with respect to Inactive Target
Evaluation Data generated during the Inactive Target Freeze Period), and Baxalta’s ability to Nominate such Inactive Target shall resume, but Precision’s obligations with respect to such

Inactive Target under Section 2.4.3(b) shall cease to apply with respect to any Third Party to which the Inactive Target Evaluation Data was disclosed during the
applicable Inactive Target Freeze Period or any of such Third Party’s Affiliates. 
 (e) Precision may, but shall not be required to,
commence additional Inactive Target Freeze Periods (including during any current Inactive Target Freeze Period) by providing the notice and opportunity to Nominate the Inactive Target as set forth in Section 2.4.3(b);
provided, however, if Precision provides any such notice during the pendency of any Inactive Target Freeze Period for any Inactive Target, Baxalta shall, notwithstanding Section 2.4.3(d), be permitted to Nominate the Target
within the [***] Inactive Target Non-Disclosure Period in accordance with Section 2.4.3(c). 

(f) Notwithstanding anything to the contrary in this Agreement, if Baxalta Nominates an Inactive Target during the applicable Inactive Target Non-Disclosure Period for such Inactive Target, then regardless of whether or not such Inactive Target becomes an Included Target as a result of the process described above, the number of available Included Targets
that may be designated by Baxalta in accordance with this Agreement, as set forth in Section 2.1, shall be reduced by one. 

2.4.4 Precision Targets. Precision shall provide no less than [***] advance written notice prior to any planned IND filing by Precision
with respect to any Variant Directed to an Inactive Target. If Baxalta does not Nominate such Inactive Target in accordance with Section 2.4.2 within [***] after the date of such notice, or thereafter such Inactive Target
fails to become an Included Target as a result of the process initiated by such Nomination, such Inactive Target shall thereafter cease to be an Inactive Target and shall be deemed to be a “Precision Target”. Precision and its
Affiliates may freely undertake and engage in, including in collaboration with Third Parties, any research, Development, Commercialization or any other activities of any kind in any field with respect to all Precision Targets with no further
obligation to Baxalta. 
 2.5 Development Licenses. 

2.5.1 Subject to the terms and conditions of this Agreement, Precision hereby grants to Baxalta a
non-exclusive, royalty-free, non-transferable (except in accordance with Section 17.1),
non-sublicensable license under the Precision Patents and Precision Know-How, solely to conduct Baxalta’s activities set forth in the applicable Development Plans
or as contemplated pursuant to Section 16.2 or 16.3 (if applicable) with respect to the Licensed Product Candidates and to otherwise conduct internal research and Development relating to Licensed Product Candidates.

 4.1.3 Batch Failure. If Precision is unable to achieve Phase II Ready Batch Success
within [***] after the date of the Commercial Option Exercise Notice with respect to a Licensed Product Candidate, then the JSC shall meet to consider (a) whether Phase II Ready Batch Success can be achieved, (b) whether it is commercially
reasonable to continue to seek to achieve Phase II Ready Batch Success and, (c) upon positive determination of (a) and (b), to develop a plan for such achievement (the “Batch Success Achievement Plan”). Following receipt
of the Batch Success Achievement Plan from the JSC, Precision will use Commercially Reasonable Efforts to perform the activities set forth in such plan as promptly as practicable. If, subsequent to the performance of the activities set forth in the
Batch Success Achievement Plan, Phase II Ready Batch Success has not been achieved, the JSC shall meet to discuss the considerations set forth in clauses (a) through (c) above, and any further obligations of Precision in relation to
manufacturing and quality testing of the Phase II Ready Batch shall be subject to the JSC’s approval of an additional Batch Success Achievement Plan. 

4.1.4 Effect of Failure to Deliver Commercial Option Exercise Notice. If Precision provides a Development Achievement Notice for a
Licensed Product Candidate Directed to a particular Included Target and Baxalta does not provide a Commercial Option Exercise Notice with respect to such Licensed Product Candidate during the applicable Commercial Option Exercise Period, then: 

(a) during any period in which (i) Baxalta holds a Commercial License for any one or more Licensed Products Directed to such Included
Target, or (ii) a different Licensed Product Candidate Directed to such Included Target is currently the subject of Development activities under a Development Plan pursuant to Section 2.2, then, subject to
Section 4.1.4(b), upon the first date following the expiration of such Commercial Option Exercise Period, neither Party shall be required nor permitted to conduct any further Development or Commercialization activities
under this Agreement with respect to the Licensed Product Candidate for which Precision provided the Development Achievement Notice; and 

(b) during any period in which (i) Baxalta does not hold a Commercial License for any one or more Licensed Products Directed to such
Included Target, and (ii) there is no Licensed Product Candidate Directed to such Included Target that is currently the subject of Development activities under a Development Plan pursuant to Section 2.2, then Precision
shall notify Baxalta of remaining Variants (which may include Unselected Candidates), if any, that Precision believes in good faith are capable of being generated by Precision via Precision Platform Technology for such Included Target in accordance
with Section 2.1.5(b). If (x) (i) the JSC determines that no such Variants exist, or (ii) the JSC does not approve a Development Plan for any one or more of such Variants for which Baxalta has expressed interest
in accordance with the process set forth in Section 2.1.5(b) within [***] after the Final Candidate Proposal Date, and (y) Baxalta does not provide a Commercial Option Exercise Notice with respect to any other Licensed
Product Candidate Directed to such Included Target (which may include a Licensed Product Candidate for which Baxalta has previously declined to timely provide a Commercial Option

disclose or make available any Precision Platform Technology. The Parties acknowledge and agree that Baxalta or its CMO(s) shall hold all manufacturing licenses with applicable Regulatory Authorities for the Licensed Products and shall be solely
responsible through itself or one or more CMOs for such manufacture. 
 6.1.4 Except to the extent otherwise expressly provided in
Section 6.1.3, each Party shall bear its own costs and expenses for effecting its respective Manufacturing and Supply Role. For clarity, Precision has no obligation to perform any manufacture or supply of Licensed Products
for Commercialization. 
 6.2 Supply Agreement. On or before a date to be established by the JSC but in no event later than [***]
prior to initiation of manufacture of any Licensed Product Candidate that will be used by Baxalta in Clinical Trials, the Parties shall enter into a Supply Agreement pursuant to which Precision or its CMO, approved by the JSC as set forth below,

Withholding Taxes. For US federal income tax purposes, Baxalta will report the payments made under this Agreement in the manner required by the US Internal Revenue Code (the “Code”). The Parties agree that this Agreement does not
constitute a financial option for US federal income tax purposes as described in section 1234 of the Code. 
 8.6 Late Payments. If
Precision does not receive payment of any sum due to it under this Agreement on or before the due date, interest shall thereafter accrue on the sum due to Precision from the due date until the date of payment, such interest to be calculated at a
rate equal to [***].

consistently applied. 
 8.8 Currency; Exchange Rate. All payments to be made under this Agreement shall be made in USD by bank wire
transfer in immediately available funds to a bank account designated by written notice from Precision. With respect to sales not denominated in USD, Baxalta shall convert each applicable quarterly sales in foreign currency into USD by using the then
current and reasonable standard exchange rate methodology applied by Baxalta in its worldwide accounting practices, consistent with U.S. GAAP, consistently applied. Based on the resulting sales in USD, the then applicable royalties shall be
calculated. The initial wire transfer instructions for Precision are set forth on Exhibit H.

Technology, such Invention shall be jointly owned by the Parties (as Joint Inventions or Joint Patents, as applicable) irrespective of inventorship, and to the extent ownership is not already vested jointly by inventorship, each Party agrees to
assign and hereby assigns such joint right, title and interest in and to such Joint Inventions (and any intellectual property rights thereto) to the other Party as is necessary for each of the Parties to own an equal, undivided interest therein, and
agrees to execute such documents and perform such other acts as the other Party may reasonably request to obtain, perfect and enforce its rights to such Joint Inventions and the assignment thereof. Such Joint Inventions and Joint Patents shall be
subject to all terms of this Agreement applicable to Joint Inventions and Joint Patents. 
 9.2 Prosecution of Patents. 

9.2.1 Non-Product-Related Precision Patents. Precision shall have sole discretion and
authority, at its sole cost and expense, with respect to filing, prosecuting and maintaining (a) all Precision Patents that do not include claims directed to CAR-Ts, human T cell engineering, one or more
Licensed Product Candidates or Licensed Products, or manufacture or components of one or more Licensed Product Candidates or Licensed Products, and (b) all Precision Platform Patents. Baxalta acknowledges and agrees that Precision has no rights
or responsibility for filing, prosecuting or maintaining the Cellectis Patents. 
 9.2.2 Product-Related Precision Patents. Precision
shall have the first right and authority to file, prosecute, and maintain the Precision Patents, other than those described in Section 9.2.1 and other than Joint Patents (collectively, “Product-Related
Patents”), on a worldwide basis in its sole discretion, subject to this Section 9.2.2. Precision shall be solely responsible for all costs and expenses incurred in connection with such filing, prosecution and
maintenance in the Territory. Precision shall provide Baxalta with the opportunity to review and comment on any and all prosecution efforts, but in no case less than [***] prior to any filing deadlines, regarding the Product-Related Patents within
the Territory; provided, that Precision shall have final control over such prosecution efforts after reasonably considering Baxalta’s comments, if any (and if Baxalta does not provide comments within [***] after such opportunity, Baxalta shall
be deemed to have no comment on such prosecution efforts). Precision shall provide Baxalta with a copy of material communications from Patent authorities in the Territory regarding

the Product-Related Patents, and shall provide drafts of any material filings or responses to be made to such Patent authorities with respect to such Product-Related Patents in a timely manner.
Notwithstanding the foregoing, if Precision determines in its sole discretion to abandon or not maintain in the Territory any Product-Related Patents (other than allowing the lapse of any provisional patent application, or abandonment of any patent
application in favor of a continuation), Precision shall provide Baxalta with at least [***] prior written notice of such determination and shall assign to Baxalta an equal, undivided interest in such Product-Related Patent and permit Baxalta, at
its discretion and expense, to continue filing, prosecution and maintenance of such Product-Related Patent. Such Product-Related Patent shall thereafter be deemed to be a Joint Patent. Baxalta’s filing, prosecution or maintenance of such
Product-Related Patent shall not change the Parties’ respective rights and obligations under this Agreement with respect to such Product-Related Patent other than those expressly set forth in this Section 9.2.2.
Baxalta will have the right to deduct any costs or expenses it incurs in the performance of filing, prosecution or maintenance of such Product-Related Patents from any amounts payable by Baxalta to Precision under this Agreement. 

9.2.3 Joint Patents. With respect to any potentially patentable Joint Inventions, the Parties shall meet and agree in good faith upon
which Party shall file, prosecute and maintain Patent applications claiming such Joint Invention in particular countries and jurisdictions throughout the Territory. The Parties will designate one or the other Party to file, prosecute and maintain
each such Patent application and coordinate their efforts as appropriate to make such prosecution activities as efficient, convenient, and harmonious as possible. All costs and expenses of filing, prosecuting and maintaining a Joint Patent shall be
shared equally by the Parties. The Party that prosecutes a particular Joint Patent (the “Prosecuting Party”) shall provide the other Party the opportunity to review and comment on any and all such prosecution efforts, but in no case
less than [***] prior to any filing deadlines, regarding the applicable Joint Patent in the particular countries and jurisdictions in the Territory, and such other Party shall provide the Prosecuting Party reasonable assistance in such efforts;
provided, that the Prosecuting Party shall have final control over such prosecution efforts after reasonably considering the other Party’s comments, if any (and if the other Party does not provide comments within [***] after such opportunity,
such Party shall be deemed to have no comment on such prosecution efforts). The Prosecuting Party shall provide the other Party with a copy of all material communications from Patent Authorities in the Territory regarding the Joint Patent being
prosecuted by such Party, and shall provide drafts of any material filings or responses to be made to such Patent authorities with respect to such Joint Patent in a timely manner. In particular, each Party agrees to provide the other Party with all
information necessary or desirable to enable the other Party to comply with any duty of candor or duty of disclosure requirements of any Patent authority. Notwithstanding the foregoing, if the Prosecuting Party determines in its sole discretion to
abandon or not maintain in any country or jurisdiction of the Territory any Joint Patent (other than allowing the lapse of any provisional patent application, or abandonment of any patent application in favor of a continuation), the Prosecuting
Party shall provide the other Party with at least [***] prior written notice of such determination and the other Party shall thereafter have the right, but not the obligation, at its sole discretion and expense, to continue filing, prosecution and
maintenance of such Joint Patent.

9.2.5 Cooperation in Prosecution. Each Party shall, at its sole cost and expense, provide the other Party all reasonable assistance and
cooperation in the Patent prosecution efforts described above in this Article IX, including providing any necessary powers of attorney and executing any other required documents or instruments for such prosecution. Such cooperation may
further include coordinating filing or prosecution of applications to avoid potential issues during prosecution (including novelty, enablement, estoppel, double-patenting and execution of amendments), and the assistance of each Party’s relevant
personnel. Each Party will use reasonable efforts via consultation with the JSC to avoid creating potential issues in prosecution of the applications for Precision Patents, Precision Platform Patents, Baxalta Patents, Isolex Platform Patents and
Joint Patents. 
 9.3 Licenses to Enabling Technologies. 

9.3.1 If Precision, in its good faith discretion, identifies any enabling technologies that are reasonably necessary for the use of Precision
Platform Technology to engineer CAR-Ts to create Licensed Product Candidates in accordance with the Development Plans under this Agreement (such technology, “Platform Enabling Technology”),

Infringement. Each Party shall provide to the Party enforcing any such rights under this Section 9.5.2(a) (the “Enforcing Party”) reasonable assistance
in such enforcement, including joining an action as a party plaintiff if so required by applicable Laws to pursue such action, at the Enforcing Party’s sole expense. The Enforcing Party shall keep the other Party regularly informed of the
status and progress of such enforcement efforts, and shall reasonably consider the other Party’s comments on any such efforts. The Enforcing Party shall bear and be responsible for all costs incurred in connection with each Party’s
activities under this Section 9.5.2(a). 
 (b) Baxalta shall have the sole and exclusive right, but not the
obligation, in its sole discretion to bring an appropriate suit or other action against any Third Party engaged in Product Infringement in the Territory based on the Baxalta Patents or Isolex Platform Patents.

not bringing an action with respect to Product Infringement under this Section 9.5.2 shall be entitled to separate representation in such matter by counsel of its own choice and at its own expense, but such Party shall at
all times cooperate fully with the Party bringing such action. Additionally, the Party not bringing an action under this Section 9.5.2 may have an opportunity to participate in such action, at its sole cost and expense, to
the extent that the Parties may mutually agree at the time the Enforcing Party elects to bring such action hereunder. 
 9.5.3 Non-Product Infringement in the Territory. 
 (a) For infringement of the Joint Patents in the
Territory that is not Product Infringement, the Parties shall confer to determine which Party shall have the first right to bring an appropriate suit or other action against the Third Party engaged in such infringement, and the manner in which the
Parties shall bear costs of and share related damage recoveries from such suit or action. The Party that brings such suit or actions (also the “Enforcing Party”) shall keep the other Party regularly informed of the status and
progress of such enforcement efforts, and shall reasonably consider the other Party’s comments on any such efforts. The other Party shall cooperate with the Enforcing Party in enforcing Joint Patents against such infringement, including joining
an action as a party plaintiff if so required by applicable Laws to pursue such action. If the Parties are unable to reach agreement upon which a Party shall bring an appropriate suit or other action against any Third Party engaged in such
infringement of such Joint Patent within [***] prior to any deadline relating to loss of any rights with respect to such infringement, whichever is earlier, then Baxalta shall have the first right, but not the obligation, to bring such suit or other
actions against such infringement in the Territory at its sole expense. The Party that does not bring such suit or action shall have the right to participate in such actions at its expense upon written notice to the other Party. The Enforcing Party

 (b) Baxalta shall have the sole and exclusive right, but not the obligation, in its sole
discretion to bring an appropriate suit or other action against any Third Party engaged in infringement that does not constitute Product Infringement in the Territory, based on the Baxalta Patents or Isolex Platform Patents. 

(c) Precision shall have the sole and exclusive right, but not the obligation, in its sole discretion to bring an appropriate suit or other

involving Precision Patents or Joint Patents in any manner that would, in the other Party’s reasonable judgment, materially and adversely impact the other Party or that would have the effect of diminishing any rights or licenses granted
hereunder, including settlements involving the ownership, validity or enforceability of any of the Precision Patents or Joint Patents, or that do not include a full and unconditional release from all liability of the other Party, without the prior
written consent of the other Party, which shall not be unreasonably withheld, conditioned or delayed. 
 9.5.5 Allocation of
Proceeds. Except as otherwise provided in this Section 9.5, if either Party recovers monetary damages from any Third Party in a suit or action described in this Section 9.5, such recovery shall
be allocated first to the repayment of costs and expenses of the Party(ies) with respect to the action (on a pro rata basis), and any remaining damages [***]. 

9.5.6 Certain Limitations. Baxalta acknowledges and agrees that (a) Precision has no rights or responsibility for enforcing the
Cellectis Patents, and therefore all references to Precision Patents or Precision Platform Patents in this Section 9.5 shall be deemed to exclude the Cellectis Patents for all purposes, (b) prior to initiating
enforcement actions against a Third Party with respect to certain Precision Patents or Precision Platform Patents which were subject to the non-exclusive license granted by Precision to Cellectis S.A. pursuant
to the Cellectis Agreement, Precision is required by the Cellectis Agreement to confirm that Cellectis S.A has not granted a license to such Third Party under such Precision Patents or Precision Platform Patents, and Baxalta will cooperate with
Precision in taking such actions as required by the Cellectis Agreement, and (c) Duke retains discretion as to whether to become a party plaintiff and has certain rights with respect to enforcement of Patent Rights contained within the Duke IP
in the event Precision does not enforce such Patent Rights.

 9.6.2 Third Party Claims. Baxalta shall assume control of the defense of any claims
brought by Third Parties alleging infringement of Third Party intellectual property rights in connection with Baxalta’s Development, manufacture, use or Commercialization of any Licensed Product in the Field in the Territory, represented by its
own counsel. If requested by Baxalta, Precision agrees to join in any such litigation, and in any event shall reasonably cooperate with Baxalta, at Baxalta’s sole cost and expense. Baxalta shall have the exclusive right to settle any such claim
without the consent of Precision, unless such settlement shall materially and adversely affect Precision’s rights under the Precision Patents, Precision Platform Patents, or Joint Patents, including on the ownership, validity or enforceability
thereof. Any costs and expenses incurred in defending any such claims shall be solely the responsibility of Baxalta (without limiting Baxalta’s rights under Section 8.4.2), provided that if Precision elects to retain
separate representation in the defense of any such claims brought by Third Parties using counsel of its own choice, it shall do so solely at its cost and expense. 

9.6.3 Potential Third Party Claims. In the event that either Party becomes aware of a Third Party intellectual property right that
might reasonably be expected to give rise to a claim of infringement under this Section 9.6, that Party shall promptly notify the other Party of such intellectual property right and all relevant facts and circumstances
known to the discovering Party. Following such notice, the Parties agree to enter into either a joint defense or common interest agreement, under which agreement the Parties can share the known facts of such infringement in reasonable detail, if
they are advised to do so by counsel, and to consult thereafter regarding any corrective or preventive action to be taken to address such potential claim. 

9.7 Patent Oppositions and Other Proceedings. 

9.7.1 By the Parties. If either Party desires to bring an opposition, action for declaratory judgment, nullity action, interference,
declaration for non-infringement, reexamination, inter partes review or other attack upon the validity, title, or enforceability of a Patent owned or controlled by a Third Party that claims, in the Territory,
any Licensed Product Candidate or Licensed Product, or the manufacture, use or Commercialization of any Licensed Product Candidate or Licensed Product (except insofar as such action is a counterclaim to or defense of, or accompanies a defense of, a
Third Party’s claim or assertion of infringement under Section 9.6, in which case the provisions of Section 9.6 shall govern), such Party shall so notify the other Party, and the Parties shall
promptly confer to determine whether to bring such action or the manner in which to settle such action. Baxalta shall have the first right, but not the obligation, to bring in its sole control and at its sole cost and expense such action in the
Territory. If Baxalta does not bring such action within [***] after notification thereof pursuant to this Section 9.7 (or earlier, if required by the nature of the proceeding), then Precision shall have the right, but not
the obligation, to bring, in Precision’s sole control and at its sole cost and expense, such action. The

Party not bringing an action under this Section 9.7 shall join the action as a joint party plaintiff if required to enable the other Party to bring such action, at the
other Party’s sole cost and expense. Additionally, if appropriate, the Party not bringing the applicable action under this Section 9.7 shall be entitled to separate representation, at its sole cost and expense, in such
proceeding by counsel of its own choice, and shall reasonably cooperate with the Party bringing such action. Any awards or amounts received in bringing any such action shall be first allocated to reimburse the Parties’ expenses in such action,
and any remaining amounts shall be retained by the Party bringing such action. 
 9.7.2 By Third Parties. 

(a) Precision Patents. If a Precision Patent becomes the subject of any proceeding commenced by a Third Party in the Territory in
connection with an opposition, reexamination request, action for declaratory judgment, nullity action, interference, inter partes review or other attack upon the validity, title or enforceability thereof, then Precision shall have the first right,
but not the obligation, to control such defense at its sole cost and expense. Precision shall permit Baxalta to participate in the proceeding to the extent permissible under applicable Laws, and to be represented by its own counsel in such
proceeding, at Baxalta’s sole cost and expense. If Precision decides that it does not wish to defend against such action, then Baxalta shall have a right to assume defense of such Third Party action. 

(b) Joint Patents. If a Joint Patent becomes the subject of any proceeding commenced by a Third Party in the Territory in connection
with an opposition, reexamination request, action for declaratory judgment, nullity action, interference, inter partes review or other attack upon the validity, title or enforceability thereof (except insofar as such action is a counterclaim to or
defense of, or accompanies a defense of, an action for infringement against a Third Party under Section 9.5, in which case the provisions of Section 9.5 shall govern), then Baxalta shall have the
first right, but not the obligation, to control such defense at its sole cost and expense. Baxalta shall permit Precision to participate in the proceeding to the extent permissible under applicable Laws, and to be represented by its own counsel in
such proceeding, at Precision’s sole cost and expense. If Baxalta decides that it does not wish to defend against such action, then Precision shall have a right to assume defense of such Third Party action. 

(c) Allocation of Costs and Proceeds. Except as set forth above, all expenses incurred by the Parties in an action under this
Section 9.7 shall be borne by the Party controlling the defense of the Third Party action. Any awards or amounts received in defending any such Third Party action, if any, shall be allocated between the Parties as provided
in Section 9.5.5 as if the Party controlling the defense of the Third Party action were the Party that brought an action against an alleged infringer. 

9.8 Patent Term Extensions in the Territory. The patent counsel of each Party shall discuss and recommend for which, if any, of the
Precision Patents and Joint Patents in the Territory the Parties should seek any term extensions, supplementary protection certificates, and equivalents thereof offering Patent protection beyond the initial term with respect to any issued Patents
(“Patent Term Extensions”) licensed to Baxalta hereunder in the Territory. If Precision consents to applying for any such Patent Term Extension (such consent not to be unreasonably withheld,

conditioned or delayed), Baxalta shall thereafter have (i) the final decision making authority with respect to applying for any such Patent Term Extensions in the Territory; provided that
Baxalta shall not unreasonably fail or refuse to do so, and (ii) the sole right to apply for any such Patent Term Extensions Baxalta decides to seek, at its expense; provided, however, that to the extent any such application for Patent Term
Extension must be filed in the name of Precision, Precision hereby grants (effective as of the date of its consent) Baxalta the power to file such application on behalf of or as agent for Precision. Precision shall cooperate fully with Baxalta, at
Baxalta’s expense, in making such filings or taking any related actions, for example and without limitation, making available all required regulatory data and information and executing any required authorizations to apply for such Patent Term
Extension. 
 9.9 Registration of License. Precision agrees that Baxalta may, if applicable, register its license under the Precision
Patents or Joint Patents with the Patent authorities in the Territory. Baxalta shall, at its expense, prepare and deliver to Precision such instruments and other documents reasonably necessary and in proper form for such registration. The Parties
shall mutually agree on the form of documents to be used for such purpose, and shall cooperate to preserve confidentiality of this Agreement to the extent permitted under applicable Laws in the relevant country. Precision shall execute and return to
Baxalta such instruments and documents within [***] from the receipt thereof.

and its Affiliates, successors and permitted assignees and each of its and their respective Agents (collectively, the “Precision Indemnitees”) from and against any and all Damages, to the extent arising out of or resulting from any
claim, suit, action, demand or other proceeding made or brought against one or more Precision Indemnitees by a Third Party in connection with (a) the gross negligence, recklessness, or intentional wrongful acts or omissions of Baxalta or its

 13.3 Indemnification Procedure. 

13.3.1 Each Party shall notify the other in the event it becomes aware of a claim for which indemnification may be sought pursuant to this
Article XIII. In case any claim, suit, action, demand or other proceeding (including any governmental investigation) shall be instituted involving any Party or its Indemnitees in respect of which indemnity may be sought pursuant to this
Article XIII, such Party (the “Indemnified Party”) shall promptly notify the other Party (the “Indemnifying Party”) in writing (an “Indemnification Claim Notice”); provided, that the failure
to promptly provide an Indemnification Claim Notice shall not relieve the Indemnifying Party of its indemnification obligations except, and only to the extent, that the Indemnifying Party is actually incrementally damaged as a result of such
failure. The Indemnifying Party and Indemnified Party shall promptly meet to discuss how to respond to any claims that are the subject matter of such proceeding. At its option, the Indemnifying Party may assume the defense of a Third Party claim
subject to indemnification as provided for in this Section 13.3 with competent counsel free of any conflict of interest with the Indemnified Party by giving written notice (a “Defense Election Notice”) to
the Indemnified Party within [***] after its receipt of the applicable Indemnification Claim Notice (the “Election Time Period”), solely for claims (a) that solely seek monetary damages and (b) as to which the Indemnifying
Party expressly agrees in writing that, as between the Indemnifying Party and the Indemnified Party, the Indemnifying Party shall be solely obligated to satisfy and discharge the claim in full (the matters described in (a) and (b), the
“Litigation Conditions”). If the Indemnifying Party does not deliver a Defense Election Notice to the Indemnified Party during the applicable Election Time Period, or if any Litigation Condition is not satisfied, the Indemnified
Party will assume responsibility for and control such defense and, without limiting the Indemnifying Party’s indemnification obligations, the Indemnifying Party will reimburse the Indemnified Party for all costs and expenses, including
reasonable attorneys’ fees, incurred by the Indemnified Party in defending itself.

 13.3.2 Upon assuming the defense of a Third Party claim in accordance with this
Section 13.3, the Indemnifying Party shall be entitled to appoint competent counsel free of any conflict of interest with the Indemnified Party in the defense of the Third Party claim. Should the Indemnifying Party assume
and continue the defense of a Third Party claim, except as otherwise set forth in this Section 13.3, the Indemnifying Party will not be liable to the Indemnified Party for any legal expenses subsequently incurred by such
Indemnified Party after the date of assumption of defense in connection with the analysis, defense, countersuit or settlement of the Third Party claim. Without limiting this Section 13.3, any Indemnified Party will be
entitled to participate in, but not control, the defense of a Third Party claim for which it has sought indemnification hereunder and to engage counsel of its choice for such purpose; provided, however, that such engagement will be at the
Indemnified Party’s own cost and expense unless (a) the engagement thereof has been specifically requested by the Indemnifying Party in writing, or (b) the Indemnifying Party has failed to assume and actively further the defense and
engage counsel in accordance with this Section 13.3 (in which case the Indemnified Party will control the defense), or (c) the Indemnifying Party no longer satisfies the Litigation Conditions. 

13.3.3 Subject to the Litigation Conditions continuing to be satisfied, the Indemnifying Party will have the sole right to consent to the
entry of any judgment, enter into any settlement or otherwise dispose of such Damages, on such terms as the Indemnifying Party, in its reasonable discretion, will deem appropriate (provided, however, that such terms (a) shall include a complete
and unconditional release of the Indemnified Party from all liability with respect thereto and (b) shall not include any admission of fault by, or impose any liability or obligation on, the Indemnified Party), and will transfer to the
Indemnified Party all amounts which said Indemnified Party will be liable to pay pursuant to such settlement or disposal of such claim prior to the time such payments become due by the Indemnified Party. With respect to all other entries of
judgment, entries into settlements or other dispositions of Damages in connection with a Third Party claim for which the Indemnifying Party has assumed the defense in accordance with this Section 13.3, the Indemnifying
Party will only have authority to consent to the entry of such judgment, entry into such settlement or such other disposition of Damages if it has obtained the Indemnified Party’s prior written consent, not to be unreasonably withheld,
conditioned or delayed. 
 13.3.4 The Indemnifying Party that has assumed the defense of the Third Party claim in accordance with this
Section 13.3 (and continues to maintain control of such defense pursuant to this Section 13.3) will not be liable for any settlement or other disposition of any Damages by an Indemnified Party that
is reached without the prior written consent of such Indemnifying Party. The Indemnified Party will not admit any liability with respect to, or settle, compromise or discharge, any Third Party claim without first offering to the Indemnifying Party
the opportunity to assume the defense of the Third Party claim in accordance with this Section 13.3. If the Indemnifying Party chooses to defend or prosecute any Third Party claim, the Indemnified Party will cooperate in
the defense or prosecution thereof and will furnish such records, information and testimony, provide such witnesses including to the extent possible, former employees and attend such conferences, discovery proceedings, hearings, trials and appeals
as may be reasonably requested in connection with such Third Party claim. Such cooperation will include access during normal business hours afforded to the Indemnifying Party to, and reasonable retention by the Indemnified Party of, records and
information that are reasonably relevant to such

reimburse the Indemnified Party for all its reasonable out of pocket expenses incurred in connection with such cooperation.

Party shall maintain, at its cost, a program of insurance or self-insurance against liability and other risks associated with its activities and obligations under this Agreement, including its Clinical Trials, its Development, use, manufacture and

9.8 and 9.9 determined mutatis mutandis as if such Reversion Patents were Precision Patents under such Sections, and (B) Section 9.2 determined mutatis mutandis as if such Reversion Patents
were Product-Related Patents under such Section. During the period in which a Valid Claim of any Reversion Patent licensed to Precision would, but for the license granted in this Section 14.3.1(a)(i) be infringed by
Development, manufacture, use or Commercialization of a particular Reversion Product in the country of sale, on a Reversion Product-by-Reversion Product, country-by-country basis, Precision shall pay to Baxalta annual (once per Calendar Year) non-refundable,

applicable). 
 (ii) Upon Precision’s request and, except in connection with termination by Precision in accordance with
Section 14.2.1 or Section 14.2.2, at Precision’s expense (including payment at the then-prevailing FTE rate for work provided by Baxalta employees), as to any or all of the following, Baxalta
shall: 
 (1) to the extent permitted by Law or the terms of any applicable Third Party agreements, assign to Precision its and its
Affiliates’ entire right, title and interest in and to all materials, licenses, Third Party agreements, preclinical and clinical data, safety data and all other supporting data that is in Baxalta’s or its Affiliates’ Control, and
deliver to Precision a copy of all relevant Know-How, in each case that relates to, and to the extent reasonably necessary for, Precision to continue the Development, use, manufacture and Commercialization of
the Reversion Products; provided, that Baxalta shall not be obligated to translate or reformat any data or to convert or adapt any database or software (it being understood that such data and databases shall be transferred on an as-is basis); 
 (2) furnish Precision with reasonable cooperation to transition to Precision the
management and continued performance of any clinical or other studies in progress then being conducted by Baxalta or its Affiliates related to the Reversion Products which Precision determines to continue in compliance with applicable Laws and
ethical guidelines applicable to the transfer or termination of any such studies; provided, that in the event that Precision informs Baxalta that it does not intend to continue specific Development activities then in progress, Baxalta shall
bear its own costs and expenses incurred in closing out such activities;

applicable, permitted to so transfer, and (C) such processes, documents, materials and other Know-How are actually used (at the time of the applicable termination) by or on behalf of Baxalta or its
Affiliates in the manufacture of the Reversion Products (in all cases, provided that Baxalta shall not be obligated to incur any costs or expenses from the use of such transferred processes, documents, materials or other Know-How by or on behalf of Precision); 
 (5) provide reasonable technical assistance relating to the
manufacture, testing and supply of the Reversion Products as necessary for Precision to be qualified or to qualify a Third Party for the manufacturing of such Reversion Products, such assistance being limited to assistance that a manufacturer

(i) Precision has materially breached the Precision Restrictive Covenants and fails to cure such breach (if capable of cure) within ninety
(90) days after receipt of Baxalta’s written notice of such breach (or, in the case of a good faith dispute as to whether a breach occurred, within ninety (90) days after a Final Determination that such breach occurred), provided, that, without
limiting the foregoing in this clause (i), any such breach of the Precision Restrictive Covenants shall be deemed material and incapable of cure if such breach resulted in Commercialization of any product comprising engineered human T cells with

supplemental hereto, to such intellectual property (including such embodiments), including any right to obtain such intellectual property (or such embodiments) from another entity, to the extent provided in the Bankruptcy Laws.

(b) this Agreement is rejected by the trustee pursuant to the Bankruptcy Laws, and (c) the Non-Debtor Party elects to retain its rights hereunder as provided in the Bankruptcy Laws, then the Debtor
Party (in any capacity, including debtor-in-possession) and its successors and assigns (including a trustee under the Bankruptcy Laws) shall provide to the Non-Debtor Party all such intellectual property (including embodiments thereof) held by the Debtor Party and such successors and assigns, or otherwise available to them, and to which the Non-Debtor Party is entitled to have access under this Agreement, immediately upon the Non-Debtor Party’s written request. Whenever the Debtor Party or any of its
successors or assigns provides to the Non-Debtor Party any of the intellectual property licensed hereunder (or any embodiment thereof) pursuant to this Section 17.14.2, the Non-Debtor Party shall have the right to perform the obligations of the Debtor Party hereunder with respect to such intellectual property, but neither such provision nor such performance by the Non-Debtor Party shall release the Debtor Party from any such obligation or liability for failing to perform it.

other Party) shall be deemed a breach of this Agreement nor create any liability for any damages, increased cost or losses which the other Party may sustain by reason of such failure or delay of performance, if the same shall arise from any cause or

action the purpose or effect of which could reasonably be expected delay, impair or impede the termination of any waiting period or the receipt of any required consents, permits, authorizations or approvals of any Governmental Authority. The Parties
shall each permit legal counsel for the other Party a reasonable opportunity to review in advance, and consider in good faith the views of the other Party in connection with, any proposed material written communication to any Governmental Authority.

control and lead all communications and strategy relating to Antitrust Laws and litigation matters relating to the Antitrust Laws (provided that Precision is not prohibited from complying with applicable Law), subject to good faith consultations
with Precision and the inclusion of Precision at meetings with Governmental Authorities with respect to any discussion related to the exercise of any Commercial Options under the Antitrust Laws.

FORM CDCP AGREEMENT TERM SHEET 
  

			
	OVERVIEW
		
	PARTIES	  	Baxalta and Precision.
		
	SUBJECT MATTER	  	This “CDCPA Term Sheet” sets forth the key terms that will be included in the form CDCP Agreement that the Parties will negotiate as contemplated by Section 7.3.3 of the Agreement.
		
	TERRITORY	  	United States, including its territories and possessions
		
	DEFINITIONS	  	 All capitalized terms used but not otherwise defined in this CDCPA Term Sheet shall have the meaning set forth in the Development and
Commercial License Agreement between Precision and Baxalta of which this Exhibit is a part (referred to as the “Agreement” for purposes of this CDCPA Term Sheet).

 
 “Regional Product” means [***].

	
	GOVERNANCE AND ALLOCATION OF RESPONSIBILITY FOR CDCP PRODUCT
		
	GOVERNANCE	  	 The Parties will establish a joint co-development and
co-promotion committee (for purposes of this CDCPA Term Sheet, the “Committee”) which shall oversee the clinical Development, manufacturing, and Commercialization of each Licensed Product for
which Precision has exercised the CDCP Option (each, a “CDCP Product”) for the Territory. The Committee shall be put in place immediately upon execution of the CDCP Agreement. The Committee will operate in substantially the same

	DEVELOPMENT	  	 The Parties will equally share all costs and expenses in connection with all aspects of further Development of the CDCP Product for the
Territory after the effective date of the CDCP Agreement.
  
 Promptly after execution
of the CDCP Agreement, the Committee will set the required form and contents of a comprehensive Development plan for the CDCP Product for the Territory, which plan will allocate responsibility to the Parties for any further Development of the CDCP
Product (the “Joint Development Plan”). The Joint Development Plan shall be appropriately coordinated with Baxalta’s global plan for Development, manufacturing and Commercialization for the CDCP Product, with Baxalta being the
sponsor of any Clinical Trials, including those that are conducted on a global basis (“Global Studies”). The Joint Development Plan will contain an estimate of the budget for the period covered by the Joint Development Plan. For
clarity, the Joint Development Plan shall not require any activity directed to Development of the CDCP Product for Commercialization outside the Territory.
  

Baxalta will prepare an initial Joint Development Plan in good faith in consultation with Precision and subject to the Committee’s review and approval.
Baxalta will review and, as necessary, update the Joint Development Plan at least annually, in each case in good faith in consultation with Precision and subject to the Committee’s review and approval. Each Party may request at any time that
the Committee approve other updates to the Joint Development Plan. All Development activities for the CDCP Product related to the Territory shall be performed in accordance with the Joint Development Plan. To the extent Third Parties are engaged
under contract by either Party to perform Development activities consistent with the Joint Development Plan, such contracts shall provide for appropriate indemnification rights that are equally protective of each Party, and to the extent Precision
engages under contract any such Third Party, all such contracts will be subject to Baxalta’s approval.
  

Promptly after executing the CDCP Agreement and concurrently with preparing the Joint Development Plan, Baxalta will prepare the initial budget for the first
year of the activities set forth in the Joint Development Plan (the “Initial Joint Development Budget”) in good faith in consultation with Precision and subject to the Committee’s review and approval. Thereafter, Baxalta will
prepare a budget for the activities under the Joint Development Plan on an annual basis prior to the beginning of the next year (each, including the Initial Joint Development Budget, an “Annual Joint Development Budget”), in each
case in good faith in consultation with Precision and subject to the Committee’s review and approval. Together with each Annual Joint Development Budget, for

Exchange Commission. Omitted portions have been filed separately with the Commission. 



  
 D-2 













 [***] 
  

			
		  	 informational purposes only, so as to facilitate Precision’s planning, Baxalta will provide a
non-binding estimate of the budget for activities remaining under the Joint Development Plan in subsequent years. In the event that Baxalta proposes an update to the Joint Development Plan that would have the
effect of deviating from the then-current Annual Joint Development Budget in an amount greater than [***]. For a CDCP Product that is not being Developed as a Regional Product, in the event that any Global Studies are conducted, [***] of the
aggregate cost of the Global Studies will be reflected in each Annual Joint Development Budget.
  

In the event that either Party reasonably expects any deviation from an Annual Joint Development Budget in excess of the percent overage threshold set forth
above is necessary to complete its Development activities, the Committee shall meet and consider any necessary adjustments to the Annual Joint Development Budget. Further, the Parties will review and reconcile on a Calendar Quarterly basis costs and
expenses of each of the Parties in connection with the Joint Development Plan.
  
 Upon
execution of the CDCP Agreement, Precision must either: (a) have cash or cash equivalents on hand, or (b) be able to reasonably demonstrate (i) anticipated cash flows, or (ii) access to cash via credit facility or otherwise, in
each case sufficient to cover its share of Development costs (in accordance with the reasonably anticipated Initial Joint Development Budget) for at least [***].

		
	COMMERCIALIZATION	  	The Parties will equally share all costs and expenses in connection with all aspects of Commercialization of the CDCP Product in the Territory. At such time as the Committee deems appropriate (with sufficient time to complete the
Joint Commercialization Plan as set forth below), the Committee will set the required form and contents of a comprehensive Commercialization plan for the CDCP Product in the Territory, which plan will allocate responsibility to the Parties for
Commercialization of the CDCP Product (the “Joint Commercialization Plan”). The Joint Commercialization Plan will contain an estimate of the budget for the period covered by the Joint Commercialization Plan. Without limiting the
foregoing, Precision’s required Commercialization activities will be limited to establishing and maintaining a sales force, but Precision may participate in other Commercialization activities subject to Baxalta approval. The Joint
Commercialization Plan will be finalized at least [***] prior to launch of Commercialization of the CDCP Product. The Joint Commercialization Plan shall be appropriately coordinated with Development, manufacturing and Commercialization activities
undertaken with respect to the CDCP Product outside the Territory, and shall not require any activity directed to Commercialization of the CDCP Product with respect to countries outside the Territory.

  

	[***]	 Confidential treatment requested pursuant to a request for confidential treatment filed with the Securities and

 [***] 
  

			
		 	 Baxalta will prepare an initial Joint Commercialization Plan in good faith in consultation with Precision and subject to the Committee’s
review and approval. Baxalta will review and, as necessary, update the Joint Commercialization Plan at least annually, in each case in good faith in consultation with Precision and subject to the Committee’s review and approval. Each Party may
request at any time that the Committee approve other updates to the Joint Commercialization Plan. All Commercialization activities for the CDCP Product in the Territory shall be performed in accordance with the Joint Commercialization Plan. To the
extent Third Parties are engaged under contract by either Party to perform Commercialization activities consistent with the Joint Commercialization Plan, such contracts shall provide for appropriate indemnification rights that are equally protective
of each Party, and to the extent Precision engages under contract any such Third Party, all such contracts will be subject to Baxalta’s approval.
  

Concurrently with preparing the Joint Commercialization Plan, Baxalta will prepare the initial budget for the first year of the activities set forth in the
Joint Commercialization Plan (the “Initial Joint Commercialization Budget”) in good faith in consultation with Precision and subject to the Committee’s review and approval. Thereafter, Baxalta will prepare a budget for the
activities under the Joint Commercialization Plan on an annual basis prior to the beginning of the next year (each, including the Initial Joint Commercialization Budget, an “Annual Joint Commercialization Budget”), in each case in
good faith in consultation with Precision and subject to the Committee’s review and approval. Together with each Annual Joint Commercialization Budget, for informational purposes only, so as to facilitate Precision’s planning, Baxalta will
provide a non-binding estimate of the budget for activities remaining under the Joint Commercialization Plan in subsequent years. In the event that Baxalta proposes an update to the Joint Commercialization
Plan that would have the effect of deviating from the then-current Annual Joint Commercialization Budget in an amount greater than [***].
  

In the event that either Party reasonably expects any deviation from any Annual Joint Commercialization Budget in excess of the percent overage threshold set
forth above is necessary to complete its Commercialization activities, the Committee shall meet and consider any necessary adjustments to the Annual Joint Commercialization Budget. Further, the
Parties will review and reconcile on a Calendar Quarterly basis costs and expenses of each of the Parties in connection with the Joint Commercialization Plan.
  

All personnel (including sales and marketing personnel) performing Commercialization activities will conform to Baxalta’s qualifications and requirements,
as will be set forth in the form CDCP Agreement.

	SALES FORCE AND PROMOTIONAL MATERIALS	  	 Baxalta will direct the training of both Parties’ sales representatives contemplated by the Joint Commercialization Plan and will
prepare and implement, in consultation with Precision, a training program and provide training materials for such sales representatives. Baxalta will specify the conduct and content of the CDCP Product training and marketing materials.

 
 Unless otherwise set forth in the Joint Commercialization Plan, each Party is solely
responsible for recruiting, hiring and maintaining its sales force for promotion of the CDCP Product in accordance with applicable Law and industry standards, its standard procedures, the Joint Commercialization Plan and the CDCP Agreement. Each
Party’s sales representatives will utilize only promotional material approved by Baxalta and all dealings shall be consistent with the approved promotional materials.
  

Baxalta will have sole authority (i) to execute medical and scientific affairs and programs based upon protocols approved by the Committee, (ii) over
all medical affairs activities related to the CDCP Product, (iii) to respond to questions and requests for information about the CDCP Product that go beyond the understanding of the sales representatives or are beyond the scope of the CDCP
Product labels and inserts. Further, Baxalta will have sole control over all other customer-facing aspects of Commercialization of the CDCP Product, including but not limited to all aspect of the development & execution of the commercial
and promotional strategy, brand name, packaging, pricing, reimbursement, contracting, promotional materials, commercial booth structure & promotional content for display at scientific forums and at other approved venues; provided, however,
for a Regional Product, development & execution of the foregoing activities shall be handled by the Committee.
  

Notwithstanding the foregoing, Precision may, by written notice to Baxalta received at least [***], elect not to field a sales force and instead to share the
costs of the Baxalta sales force for promotion of the CDCP Product in accordance with the Profit & Loss Share below.

	REGULATORY	  	The Parties will assume through the Committee joint responsibility for all regulatory matters regarding seeking Regulatory Approval in the Territory, which shall be part of the Joint Development Plan. Baxalta will take the lead and
have final authority with respect to regulatory activities for seeking Regulatory Approval for the CDCP Product, provided that Precision will have the right (i) to review and provide comments on all Regulatory Materials in the Territory other

 Baxalta and Precision BioSciences form Global Genome Editing 

Collaboration in Immuno-Oncology 
  

	 	•	 	 Baxalta and Precision BioSciences to utilize proprietary ARCUS genome editing technology to develop an allogeneic
CAR T cell therapeutic pipeline 


  

	 	•	 	 Precision BioSciences to receive $105 million upfront, in addition to potential future milestone payments
and royalties 


 BANNOCKBURN, Ill. and DURHAM, N.C., Feb [    ], 2016 – Baxalta
Incorporated (NYSE: BXLT), a global biopharmaceutical leader dedicated to delivering transformative therapies to patients with orphan diseases and underserved conditions, and Precision BioSciences, the genome editing company, today announced a
global collaboration to develop a broad series of allogeneic chimeric antigen receptor (CAR) T cell therapies directed towards areas of major unmet need in multiple cancers. 

CAR T is widely recognized as a breakthrough technology with the potential to become a curative option for certain malignancies. Most CAR T cell therapy
technologies isolate cells from cancer patients’ blood and re-engineer them to specifically target receptors on tumor cells. The reprogrammed cells are multiplied in a laboratory and then returned to the
patient to target the tumor. This approach has had initial success in clinical trials for certain tumor types, but persistent scaling challenges remain based on the highly personalized nature of the therapy. Precision BioSciences’ proprietary
ARCUS genome editing technology enables the production of CAR T cells derived from healthy donors rather than relying on the patient. This approach aims to overcome the manufacturing-related limitations with existing CAR T therapies and enable a
broader range of malignancies to be targeted. 
 “Collaborating with Precision BioSciences enables Baxalta to accelerate innovation in immuno-oncology
with a next-generation, donor-derived CAR T strategy using a proprietary combination of genome editing expertise and technology,” said David Meek, executive vice president and president, Oncology, Baxalta. “Combining Precision
BioSciences’ ARCUS technology with Baxalta’s global infrastructure, expertise and growing immuno-oncology portfolio is a synergistic approach that we believe has the potential to make disruptive approaches available to people with a range
of underserved cancers.” 












 “Baxalta is an ideal partner in CAR T for Precision and our ARCUS genome editing platform because of
their global reach, collaborative business model, and long-term commitment to succeeding in immuno-oncology,” said Matthew Kane, CEO of Precision BioSciences. “We look forward to working closely with the team at Baxalta to develop
novel CAR T therapeutics that could transform the treatment of cancer.” 
 Under the terms of the agreement, Baxalta and Precision BioSciences will
develop CAR T therapies for up to six unique targets, with the first program expected to enter clinical studies in late 2017. Precision BioSciences will be responsible for performing early-stage research activities up to Phase 2, following which
Baxalta has the exclusive right to opt in for late-stage development and commercialization. Precision BioSciences will receive an upfront payment of $105 million from Baxalta, with additional option fees, developmental, clinical, regulatory,
and sales milestones, potentially totaling up to $1.6 billion, in addition to royalties on worldwide sales. Precision also has the right to participate in the development and commercialization of any licensed products resulting from the
collaboration through a 50/50 co-development and co-promotion option in the United States. Additional terms and initial targets were not disclosed. 

The agreement follows another recently established Baxalta collaboration to advance novel therapeutics against checkpoint targets, advancing the
company’s strategic commitment to investing in immuno-oncology and building an innovative portfolio of cancer immunotherapies.
