Adaptimmune shall (i) within a reasonable period of time after agreement of the Development Plan assign the responsibility for each activity of each Project Phase to specific personnel; (ii) monitor progress of each activity of each Project Phase during the performance thereof; (iii) set suitable and appropriate objectives to ensure, to the extent reasonably possible, that each end point within any Project Phase is met in

accordance with agreed timescales; (iv) allocate resources or additional resources to ensure performance of each Project Phase in accordance with agreed timescales and specifications.

3.4. Each Party shall provide cooperation and information as reasonably necessary to assist the other Party in performing the Collaboration Program. A Party shall not be responsible for any delay or suspension of any Collaboration Program where such delay or suspension is caused by any failure of the other Party to provide any information, assistance or cooperation.

3.5. On a Collaboration Program-by-Collaboration Program basis (excluding the Research Pool Program and the Initial Target Program), at any time during the conduct of Project Phase 1 of such Collaboration Program through the twenty one (21) Business Day period following Completion of Project Phase 1 of such Collaboration Program, Adaptimmune shall either (i) make a recommendation to the JSC that a Therapy satisfies the applicable Lead Candidate Criteria, or (ii) advise the JSC that no Therapy satisfies the applicable Lead Candidate Criteria, but that additional research is likely to result in a Lead Candidate; or (iii) advise the JSC that no Therapy satisfies the applicable Lead Candidate Criteria and that in Adaptimmune’s reasonable discretion, it is not technically feasible to develop a Lead Candidate under the applicable Collaboration Program. The foregoing recommendations and advisements shall be made on the basis of all available Results which shall be shared with GSK via the JSC.

3.5.1. Within twenty one (21) Business Days after recommendation by Adaptimmune of the potential Lead Candidate in accordance with Section 3.5(i) above, the JSC will decide on the nomination of one or more Lead Candidate(s) to progress to Project Phase 2. Upon the JSC’s determination that at least one Therapy satisfies the applicable Lead Candidate Criteria, such Therapy shall be deemed a Lead Candidate and shall be progressed into Project Phase 2A development. If the JSC does not select any of the proposed Lead Candidates within twenty one (21) Business Days of submission by Adaptimmune, then the JSC may specify within a further twenty one (21) Business Days what additional research activities, if any, that were not included in the applicable Development Plan are required to enable at least one (1) Therapy to achieve the Lead Candidate Criteria (“Lead Additional Work”). Promptly thereafter, the Parties will amend the applicable Development Plan to reflect any such Lead Additional Work and Adaptimmune shall conduct such Lead Additional Work. If no Lead Additional Work is agreed or no Lead Candidate is nominated by the JSC within twenty one (21) Business Days after Completion of such Lead Additional Work, then GSK shall terminate the applicable Collaboration Program in accordance with Section 13.3 and Section 13.6 shall apply.

3.5.2. Within twenty one (21) Business Days after advising the JSC that no Therapy satisfies the Lead Candidate Criteria in accordance with Section 3.5(ii) or (iii), then the JSC shall either (i) specify within a further twenty one (21) Business Days what Lead Additional Work, if any, is required to enable at least one (1) Therapy to achieve the Lead Candidate Criteria, or (ii) decide to terminate the applicable Collaboration Program. In the event that Section 3.5.2(i) occurs, the Parties will amend the applicable Development Plan to reflect any such Lead Additional Work and Adaptimmune shall conduct such Lead Additional

Work. If no Lead Candidate is nominated by the JSC within twenty one (21) Business Days after Completion of the Lead Additional Work, then GSK shall terminate the applicable Collaboration Program in accordance with Section 13.3 and Section 13.6 shall apply.

3.6. On a Collaboration Program-by-Collaboration Program basis (excluding the Research Pool Program or the Initial Target Program’s Generation 1 Therapy), at any time during the conduct of Project Phase 2 of such Collaboration Program through the twenty one (21) Business Day period following Completion of Project Phase 2 of such Collaboration Program, Adaptimmune shall either (i) make a recommendation to the JSC that a Lead Candidate satisfies the applicable Clinical Development Candidate Criteria, or (ii) advise the JSC that no Lead Candidate satisfies the applicable Clinical Development Candidate Criteria, but that in Adaptimmune’s reasonable discretion, additional research is likely to result in a Clinical Development Candidate; or (iii) advise the JSC that no Lead Candidate satisfies the applicable Clinical Development Candidate Criteria and that in Adaptimmune’s reasonable discretion, there is no additional research that will result in a Clinical Development Candidate because it is not technically feasible to develop a Clinical Development Candidate under the applicable Collaboration Program. The foregoing recommendations and advisements shall be made on the basis of all available Results which shall be shared with GSK via the JSC.

3.6.1. Within twenty one (21) Business Days after recommendation by Adaptimmune of the potential Clinical Development Candidate in accordance with Section 3.6(i), the JSC will decide on the nomination of a Clinical Development Candidate. Upon the JSC’s determination that at least one Lead Candidate satisfies the applicable Clinical Development Candidate Criteria, such Lead Candidate shall be deemed the Clinical Development Candidate. If the JSC does not select any proposed Clinical Development Candidate within twenty one (21) Business Days of submission by Adaptimmune, then the JSC may specify within a further twenty one (21) Business Days what additional research activities, if any, that were not included in the applicable Development Plan are required to enable at least one (1) Lead Candidate to achieve the Clinical Development Candidate Criteria (the “Development Additional Work”). Promptly thereafter, the Parties will amend the applicable Development Plan to reflect any such Development Additional Work and Adaptimmune shall conduct such Development Additional Work. If no Development Additional Work is agreed or no Clinical Development Candidate is nominated by the JSC after Completion of such Development Additional Work, then GSK shall terminate the applicable Collaboration Program in accordance with Section 13.3 and Section 13.6 shall apply.

3.6.2. Within twenty one (21) Business Days after advising the JSC that no Lead Candidate satisfies the Clinical Development Candidate Criteria in accordance with Section 3.6(ii) or 3.6(iii), then the JSC may either (i) specify within a further twenty one (21) Business Days what Development Additional Work is required to enable one (1) Lead Candidate to achieve the Clinical Development Candidate Criteria, or (ii) decide to terminate the applicable Collaboration Program. In the event that Section 3.6.2(i) occurs, the Parties will amend the applicable Development Plan to reflect any such Development Additional Work and Adaptimmune shall conduct such Development Additional Work. If no Clinical Development Candidate is nominated by the JSC after

Completion of the Development Additional Work, then GSK shall terminate the applicable Collaboration Program in accordance with Section 13.3 and Section 13.6 shall apply.

3.7. In relation to any Lead Additional Work or Development Additional Work agreed by the JSC under Sections 3.5.1, 3.5.2, 3.6.1 or 3.6.2, any additional time and effort incurred by Adaptimmune shall be at the cost of Adaptimmune where the time and effort already incurred during Project Phase 1 or Project Phase 2, as applicable, of such Collaboration Program, together with the Lead Additional Work or Development Additional Work, as applicable, does not exceed the maximum amount of resource allocation and costs by Adaptimmune for the Project Phase in the relevant Development Plan. In calculating the cost of such additional time and effort, such time and effort shall be calculated at Adaptimmune’s FTE Rate as at the date such time and effort are incurred. Any time and effort above such level shall be at GSK’s cost, as calculated on Adaptimmune’s relevant FTE Rate as at the date such time and effort are incurred.

3.8. Subject to the terms of this Agreement, the Parties shall have the right to engage subcontractors (including for clarity Affiliates) to perform certain of its obligations under the Collaboration Programs, and such subcontractors shall be assigned the applicable obligation as set forth in the agreed Development Plans; provided, that GSK shall have the right to approve (such approval not to be unreasonably withheld) any subcontractors used by Adaptimmune to conduct any work under a Development Plan after achievement of a Clinical Development Candidate, including any contract manufacturing organization or other entity engaged to conduct manufacturing process work as described in the Initial Development Plan. Any subcontractor to be engaged by a Party to perform a Party’s obligations under a Collaboration Program shall meet the qualifications typically required by such Party for the performance of work similar in scope and complexity to the subcontracted activity and shall agree in writing to comply with the applicable terms of this Agreement (including confidentiality terms); provided, that any Party engaging a subcontractor hereunder will remain responsible for the actions and omissions of any subcontractor to whom it delegates its obligations under this Agreement including to the extent such actions or omissions result in a breach of the terms of this Agreement. Save in relation to any agreements already agreed between Adaptimmune and any Third Party as at the Effective Date and provided such agreements are included within the Due Diligence Dataroom, any Party engaging a subcontractor shall in all cases retain or obtain ownership of any and all Intellectual Property Rights arising as a result of performance of any sub-contracted activity under the Development Plan and any subcontract agreement shall state that such subcontractor has no rights to use any Intellectual Property Rights owned or Controlled by the other Party save as strictly necessary for performance of the subcontracted activities. Any subcontractor shall not be entitled to further subcontract its obligations under this Agreement except in the case of any subcontracts or sub-licenses described in Section 6.8. ***

3.9. Collaboration Program Expenses.

3.9.1. Except as provided in Section 3.7, 5.1.3, 11.9.2(b)(i) or in this Section 3.9, each of the Parties shall be responsible for its own costs and expenses incurred in performing any Collaboration Program or the Research Pool Program, as applicable. Adaptimmune shall provide the JSC with quarterly reports (the first to be provided within 30 days following the first full calendar quarter after the Effective Date) detailing its progress under all Collaboration Programs and the Research Pool Program including incurring of costs and expenses. If the JSC amends any Development Plan or the Research Pool Program in a manner that would cause Adaptimmune’s costs of such Collaboration Program or the Research Pool Program to be additive or incremental to the anticipated maximum resource allocation for such Collaboration Program or the Research Pool Program, then GSK shall be responsible for such incremental Adaptimmune costs (with such costs being based on Adaptimmune’s FTE Rate as at the time such increased effort is incurred); provided, that GSK shall not be responsible for such costs if the amendment to the Development Plan or Research Pool Program was due to Adaptimmune’s failure to use Commercially Reasonable Efforts, negligence or other breach of obligations under this Agreement with respect to the conduct of the Development Plans or Research Pool Program. For the avoidance of doubt, if any such amendment approved by the JSC substitutes new work for work set forth in the original Development Plan or Research Pool Program without increasing costs, or adds activities that do not result in increased costs, then Adaptimmune shall be responsible for such non-additive costs. In addition, if repeat work is required to be conducted by a subcontractor or sublicensee or Adaptimmune and Adaptimmune does not have to pay for such repeat work from the subcontractor or sublicensee (for example because such repeat work is at the cost of the subcontractor under Adaptimmune’s agreement with such subcontractor), then Adaptimmune shall be responsible for costs associated with such repeat work and GSK shall be under no obligation to compensate Adaptimmune for the cost of repeat work carried out by such subcontractor or sublicensee. Neither Party will be responsible or liable under this Agreement for any delay to a Collaboration Program, Research Pool Program or delay to the development of any Licensed Product to the extent caused by a failure of the JSC to agree to amend the applicable Development Plan or Research Pool Program as described above and Adaptimmune will not be responsible for any such delay caused by GSK’s failure to agree to pay Adaptimmune’s increased costs associated with such changes.

3.9.2. Notwithstanding the foregoing, to the extent that the JSC approves a change to the Initial Development Plan to include additional Clinical Trial cohorts required to address feedback from the FDA on the manufacturing process referred to as CMC Version 1.5 in the Initial Development Plan, then the provisions of this Section 3.9.2 shall apply and not the provisions of Section 3.9.1 with respect to costs associated with such additional cohorts. If such costs are additive or incremental to the anticipated maximum resource allocation for the Initial Development Plan, then the Parties shall share equally such incremental costs (with such costs being based on Adaptimmune’s FTE Rate as at the time such additional cohorts are conducted). GSK shall reimburse Adaptimmune for such costs on a quarterly basis, within *** after receipt of an invoice from Adaptimmune.

***Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

3.10. Any process design decisions that require CMO or other agreed capital expenditure and which have been approved to be incurred by the JSC in accordance with Section 4.13 shall be reimbursed or paid by GSK. Any payment or reimbursement by GSK will be subject in each case to (i) GSK’s approval of the applicable CMO or Third Party to the extent not already obtained and in each case not to be unreasonably withheld or delayed and (ii) Adaptimmune procuring access for GSK to such CMO or Third Party in order to explore funding models and to leverage any existing relationship with such CMO or Third Party. Where any such capital expenditure results in the acquisition or installation of assets which are being used by Adaptimmune for purposes other than any Collaboration Program or Research Pool Program, the relevant capital expenditure to be reimbursed or paid by GSK shall be apportioned between GSK and Adaptimmune, the amount of such capital expenditure to be paid by Adaptimmune being agreed between the Parties based on then-current and planned future uses of such assets.

4. Governance; Collaboration Program Management

4.1. Within fifteen (15) Business Days of the Effective Date, the Parties will assign representatives to form a joint steering committee (the “JSC”). The JSC shall be responsible for overseeing the conduct of all Collaboration Programs, and approving the detailed requirements and deliverables for any Collaboration Program as developed by the JPT and/or JMC. The JSC shall have oversight and decision-making responsibilities for activities performed for each Collaboration Program and shall resolve disputes arising at the JPT and JMC. The JPT and JMC (where applicable) shall keep the JSC informed of the progress and activities under each Collaboration Program. The JSC shall be comprised of four (4) representatives (or such other number of representatives as the Parties may agree) from each of GSK and Adaptimmune. Each Party may replace any or all of its representatives on the JSC at any time upon written notice to the other Party in accordance with Section 16.1 or by e-mail to the other Party’s Alliance Manager. Each representative of a Party shall have sufficient seniority and appropriate expertise in biotechnology and pharmaceutical drug discovery and development to participate on the JSC. Each Party may, subject to the other Party’s prior approval, invite non-member representatives of such Party to attend meetings of the JSC as non-voting participants, subject to the confidentiality obligations of Article 10, as may be required by the agenda for such meetings. The Alliance Managers shall also participate as non-voting members in JSC meetings.

4.2.16. such other responsibilities as may be assigned to the JSC pursuant to this Agreement or as may be mutually agreed by the Parties from time to time.

4.3. Save as provided under Section 4.7, the JSC shall meet quarterly or more or less frequently as agreed by the Parties and chairing of the meetings shall be alternated between each Party’s designated representative, unless otherwise agreed. The meetings shall be held at the premises of the Party chairing the meeting unless otherwise agreed. The Parties may also agree to hold such meeting by telephone or video conference or webinar although at least one (1) meeting in any Year shall be in person to the extent possible. The first meeting shall be chaired by Adaptimmune and shall be held within thirty (30) days of the Effective Date. The Alliance Manager for the Party chairing each meeting shall be responsible for arranging the date of the meeting and shall circulate an agenda for the meeting at least ten (10) Business Days prior to the agreed date for the meeting. The other Party shall be entitled to comment on and add items to the agenda and re-circulate the agenda at least five (5) Business Days ahead of the agreed date of the meeting. The Parties shall each be responsible for their own costs and expenses

incurred in participating and attending JSC meetings. Copies of data and proposals to be discussed shall be circulated by each Party at least forty eight (48) hours prior to each JSC meeting where reasonably possible.

4.4. The Alliance Manager from the Party that is not the chairing Party shall be responsible for preparing and circulating minutes, within fifteen (15) Business Days of each meeting of the JSC, setting forth, inter alia, an overview of the discussions at the meeting and a list of any actions and decisions approved by the JSC and a list of any issues to be resolved by the Executive Officers pursuant to Section 4.5. Such minutes shall be effective only after approved by both Parties in writing. With the sole exception of specific items of the meeting minutes to which the members cannot agree and that are escalated to the Executive Officers as provided in Section 4.5, definitive minutes of all JSC meetings shall be finalized no later than twenty five (25) Business Days after the meeting to which the minutes pertain. If, at any time during the preparation and finalization of the JSC minutes, the Parties do not agree on any issue with respect to the minutes, such issue shall be resolved by the escalation process set forth in Section 4.5. The decision resulting from the escalation process shall be recorded by the Alliance Manager in amended finalized minutes for such meeting.

4.5. Decisions of the JSC shall be made on a unanimous basis with each Party having one vote on the JSC (irrespective of the number of attendees from each Party at any JSC meeting). In the event of any inability to reach a decision at a JSC meeting, the matter may be referred by either Party to in the case of Adaptimmune, the CEO of Adaptimmune and in the case of GSK, the President of Pharma R&D (or his designee) for resolution (the “Executive Officers”). Where resolution is still not possible within fifteen (15) Business Days of referral to the Executive Officers, GSK shall have the final decision-making authority save that GSK shall not be entitled to resolve any dispute in a way which would (a) require amendment of this Agreement; or (b) materially increase or change the scope of work, cost or expenses of Adaptimmune under any agreed Development Plan for any Collaboration Program or result in a *** to the Collaboration Program; or (c) result in Adaptimmune losing any ownership interest in any Collaboration Program IP; or (d) place patients at excessive risk or which might be reasonably considered to place patient health and safety at risk in any Clinical Trial conducted by Adaptimmune in accordance with a Development Plan; or (e) result in a change to the contributions of the Parties to the Development Plans including as to which Party contracts with any CMO or other subcontractor. For the avoidance of doubt, a ***

effective; provided, that if multiple JPTs are needed due to different Targets or disease areas, then the Parties may establish separate JPTs for different Collaboration Programs. The JPT shall be comprised of representatives from each of GSK and Adaptimmune with the appropriate scientific expertise with respect to the conduct of the Development Plans (and such representatives may vary depending on the relevant Project Phase) and shall meet on a monthly basis (or more or less frequently as agreed by the Parties) at Adaptimmune’s facilities, GSK’s facilities or via teleconference at such times as may be agreed by the Parties during the term of the applicable Collaboration Program. The JPT will report to the JSC and will be responsible for the day-to-day management of the conduct of the Development Plans including any non-material changes to the Development Plans, overseeing the conduct of experiments and reviewing data resulting from such experiments as set forth in the Development Plans, proposing amendments to the Development Plans, proposing new Development Plans to the JSC for new Collaboration Programs for JSC approval, discussing potential Lead Candidates and Development Candidates for proposal to the JSC. All decisions of the JPT on matters for which it has responsibility shall be made unanimously. In the event that the JPT is unable to reach a unanimous decision within ten (10) Business Days after it has met and attempted to reach such decision, then either Party may, by written notice to the other, have such issue submitted to the JSC for resolution in accordance with Section 4.5. Each Party will bear all expenses it incurs in regard to participating in all meetings of the JPT, including all travel and living expenses. Each JPT shall automatically cease to exist on completion of the relevant Collaboration Programs that it supports and exercise or expiry of all Collaboration Program Options applicable to such Collaboration Programs.

4.7. Where any Party wants to materially amend the services or tasks allocated under any Development Plan (whether under Section 3.2 or otherwise and subject to Section 4.5) it shall notify the JSC of such desire to amend. The notification shall include details of the changes being requested and the impact such changes will have on the remainder of the Development Plan including any impact on timescales. Unless the request needs to be determined ahead of the next JSC meeting, any amendment to the Development Plan will be discussed at the next JSC meeting and the request for change will be added to the agenda for the next meeting. Where a request needs to be determined more quickly, the JSC may call a special meeting to resolve the matter ahead of the next scheduled JSC meeting. The chair of such special meeting shall be the same chair as for the next JSC meeting. Minutes of the special meeting will be circulated and prepared in accordance with Section 4.4.

4.8. The JSC shall not have any authority to amend the terms of this Agreement or to add Collaboration Programs in excess of the fifteen (15) Collaboration Programs permitted under this Agreement (namely five (5) Target Programs and ten (10) HLA Programs). The foregoing provisions of this Article 4 notwithstanding, neither Party shall have the right to exercise its final decision-making authority to unilaterally: (a) determine that it has fulfilled any obligations under this Agreement or that the other Party has breached any obligation under this Agreement; (b) make a decision that is expressly stated to require the mutual agreement of the Parties; or (c) otherwise expand its rights or reduce its obligations under this Agreement.

4.9. From time to time, the JSC may establish subcommittees to oversee particular projects or activities, as it deems necessary or advisable (each, a “Subcommittee”). Each Subcommittee shall consist of such number of members as the JSC determines is

appropriate from time to time. Such members shall be individuals with expertise and responsibilities in the relevant areas over which such Subcommittee shall have oversight and/or decision-making authority.

4.10. The JSC shall automatically cease to exist on completion of all Collaboration Programs and exercise or expiry of all Initial Program Options and all Collaboration Program Options. The JSC’s involvement in relation to any particular Collaboration Program shall cease on the earlier of termination of such Collaboration Program in accordance with Article 13 or exercise of the Option in relation to any Collaboration Program. Following termination of the JSC, communication between the Parties shall be via the Alliance Managers and each Party shall make its Alliance Manager available at least twice per Year in person or by telephone and on provision of thirty (30) days written notice to discuss any updates or reports provided in accordance with this Agreement.

4.11. Promptly after the Effective Date, each Party shall appoint an individual to act as alliance manager for such Party (each, an “Alliance Manager”). Each Alliance Manager shall thereafter be permitted to attend meetings of the JSC as a non-voting observer, subject to the confidentiality provisions of Article 10. The Alliance Managers shall be a primary point of contact for the Parties regarding the collaboration activities contemplated by this Agreement or other reporting obligations under this Agreement and shall facilitate all such activities hereunder. The Alliance Managers shall also be responsible for assisting the JSC in performing its oversight responsibilities with respect to the activities of the JPT, as well as by preparing and finalizing the minutes from meetings of the JSC. The name and contact information for such Alliance Managers, as well as any replacement(s) chosen by Adaptimmune or GSK, in their sole discretion, from time to time, shall be promptly provided to the other Party in accordance with Section 16.1 of this Agreement.

4.12. Within thirty (30) days after the Effective Date, the Parties shall each designate representative(s) to consult with the other Party’s representative(s) with respect to patent prosecution, defence and enforcement matters (the “Patent Liaisons”) as more fully described in this Section 4.12. The Patent Liaisons shall discuss, at such times, places and frequencies as either Patent Liaison determines is necessary, material issues and provide input to each other regarding the prosecution, maintenance, enforcement or defence of Adaptimmune Background, Adaptimmune Collaboration Program IP, Joint Collaboration Program IP and Joint Background and in each case in accordance with the rights granted under Article 7. The Patent Liaisons shall be responsible for coordinating the implementation of each Party’s strategies for the protection of the foregoing Intellectual Property Rights in accordance with the terms of this Agreement. All final decisions related to the prosecution, maintenance, enforcement or defence of any Adaptimmune Background, Adaptimmune Collaboration Program IP, Joint Collaboration Program IP and Joint Background shall be made by the Prosecuting Party (as defined in Section 7.3.6).

4.13. Joint Manufacturing Committee. The Parties shall form a Joint Manufacturing Committee (“JMC”) as a Sub-committee to the JSC. The JMC shall be formed within thirty (30) days after the Effective Date and shall include three (3) representatives from each Party (or such other number as mutually agreed by the Parties), in each case suitably qualified to assist in the development and co-ordination of the manufacturing process development forming part of the Initial Target Program, including process, analytical, quality and supply expertise. The JMC shall meet on a monthly basis (or more or less

frequently as agreed by the Parties) at Adaptimmune’s facilities, GSK’s facilities or via teleconference at such times as may be agreed by the Parties during the term of the applicable Collaboration Program. Each Party may, subject to the other Party’s prior approval, invite non-member representatives of such Party to attend meetings of the JMC as non-voting participants, subject to the confidentiality obligations of Article 10, as may be required by the agenda for such meetings. The JMC will coordinate with the JPT assigned to the Initial Target Program as required or useful, will report to the JSC and will be responsible for the day-to-day management of the manufacturing process development activity within the Initial Target Program including proposing amendments to the Development Plan regarding such manufacturing processes for review by JSC. The JMC shall also identify any manufacturing process decisions which will result in any CMO or other Third Party capital expenditure to be approved and reimbursed by GSK as set forth in Section 3.10 and will be the forum at which Adaptimmune shall keep GSK informed of any quality or compliance issues or financial issues with Adaptimmune’s CMOs of which Adaptimmune becomes aware. For clarity any such expenditure shall need to be prior approved by GSK in writing before being incurred. All decisions of the JMC on matters for which it has responsibility shall be made unanimously. In the event that the JMC is unable to reach a unanimous decision within ten (10) Business Days after it has met and attempted to reach such decision, then either Party may, by written notice to the other, have such issue submitted to the JSC for resolution in accordance with Section 4.5. Each Party will bear all expenses it incurs in regard to participating in all meetings of the JMC, including all travel and living expenses. The JMC shall automatically cease to exist on completion of the Initial Target Program and the Second Target Program (if Adaptimmune conducts manufacturing activities under the Second Target Program), as the case may be, and completion of the technology transfer requirements set forth in Section 6.11 and Schedule 7 as they relate to the Initial Target Program and Second Target Program, respectively.

5. Collaboration Programs — Development Plans; Target Nomination

5.1. Target Programs.

5.1.1. GSK has the right to nominate up to five (5) Targets (each, a “Nominated Target”) to be the subject of Collaboration Programs as set forth in this Article 5 (each Collaboration Program directed to a Nominated Target, being a “Target Program”). Each such Target Program shall relate to a different Nominated Target. The Initial Target is deemed nominated as at the Effective Date and shall be the subject of the first Target Program (the “Initial Target Program”).

5.1.2. Within six (6) months of the Effective Date, the Parties will collaborate and jointly nominate three (3) Targets other than the Initial Target subject to JSC approval, such three (3) nominated Targets constituting the “Research Pool”. The JSC shall agree the activities, specification and scope of activities to be conducted by Adaptimmune (the “Research Pool Program”) as soon as reasonably possible after the Effective Date and such Research Pool Program shall be designed to assess whether any of the Targets in the Research Pool meet the Lead Candidate Criteria. The Research Pool Program shall be added to the Agreement as a Schedule once agreed. Adaptimmune shall perform the Research Pool Program in the same way as if such Research Pool Program was a Collaboration Program including as relevant performance

in accordance with Section 3.2.

5.1.3. Following Completion of the Research Pool Program and provision to GSK of all Results arising from the performance of activities in the Research Pool Program, GSK and Adaptimmune shall collaborate to answer any additional or further questions GSK has in relation to its decision to select a Target from the Research Pool to be the subject of a Collaboration Program as set forth in this Section 5.1.3. Such further collaboration shall not include any further testing or development work by Adaptimmune. Within three (3) months after Completion of the Research Pool Program and provision to GSK of all Results arising from the performance of activities in the Research Pool Program (the “Second Target Nomination Period”), GSK shall have the first right to nominate a Target from the Research Pool as the second Nominated Target (“Second Target”) to be the subject of a Collaboration Program (the “Second Target Program”). Following such nomination the Parties shall agree the Development Plan relating to such Second Target in accordance with Section 5.3.7, such Development Plan to include completion of work for an IND filing excluding any contract manufacturing activities. The Parties intend that GSK will conduct or have conducted manufacturing activities with respect to the Second Target Program; provided, that GSK shall have the right to require Adaptimmune to conduct contract manufacturing activities by contractors approved by GSK as agreed in the Development Plan and such activities shall constitute additional work payable by GSK, the cost being calculated on Adaptimmune’s relevant FTE rate as at the date such time and effort are incurred, with Third Party costs directly reimbursable by GSK in accordance with a plan mutually agreed by the Parties. Once GSK has nominated a Second Target it shall have no right to nominate the other Targets from the Research Pool in accordance with Section 5.3 unless otherwise agreed with Adaptimmune in writing.

5.1.4. GSK shall not have any right to nominate any further Targets other than the Initial Target and the Second Target until such time as GSK has (i) *** ; or (ii) ***

. Following occurrence of either of the foregoing, GSK shall have the right to nominate up to two (2) additional Targets in the manner set forth in Section 5.3 and during the Dataroom Period.

5.1.5. GSK shall be entitled to nominate the fifth Target only once GSK has *** and during the Dataroom Period.

5.2. HLA Programs. Each Target Program under Section 5.1 above shall be specific to a designated HLA allele. GSK also has the right to nominate further HLA alleles per Nominated Target (each, a “Nominated HLA”) up to a maximum of a total of ten (10) and to be the subject of further Collaboration Programs as set forth in this Section 5.2 (each Collaboration Program directed to a Nominated HLA, an “HLA Program”). GSK may not exercise its right to nominate a Nominated HLA associated with a Nominated Target until such time as GSK has (i) *** ; or (ii) *** in which case GSK shall be entitled to nominate HLA alleles for HLA Programs, to be capped at a number that is twice the number of Nominated Targets at such time (up to a maximum of a total of 15 Target

Programs). Following *** by GSK, GSK shall be entitled to nominate any remaining entitlement to HLA Programs.

5.3. Nomination Process.

5.3.1. The Dataroom shall be available to GSK for the Dataroom Period and GSK shall be required to select the fifth (5th) Target (if applicable) prior to expiry of the Dataroom Period. The same information as provided in the Dataroom shall also be available to all partners, licensees and potential licensees of Adaptimmune. Adaptimmune warrants that, as of the Effective Date the same information has been, and for the Dataroom Period will be, provided to GSK in the Dataroom in relation to Targets as has been or will be provided to other potential licensees and partners of Adaptimmune (each an “Entity”) who have been granted access or will be granted access to the Dataroom as of the Effective Date or during the Dataroom Period (excluding any information relating to Targets which have been exclusively licensed to any Third Party prior to the Effective Date or which have been removed under Section 5.3.4). Adaptimmune may add further Targets to the Dataroom in its absolute discretion. For clarity there shall be no obligation on Adaptimmune to add any Targets to the Dataroom where such Targets have been provided by any Third Party and such Third Party has not consented to inclusion of the Targets within the Dataroom.

5.3.2. Except for the Initial Target, GSK shall nominate a Target or HLA by providing notice in writing in the form set out in Schedule 8 to Adaptimmune (the “Nomination Notice”). The Nomination Notice shall specify either (a) the Target being nominated together with the HLA allele to which any Therapy directed at the Target should first be developed; or (b) the new HLA allele to which any Therapy should be directed for a Nominated Target that is the subject of a pre-existing Target Program. Adaptimmune shall have five (5) Business Days from receipt of Nomination Notice to accept or reject the Nomination Notice by signing and returning a completed Nomination Notice to GSK; provided that a Nomination Notice may only be rejected in accordance with Section 5.3.4 below and shall be accepted by Adaptimmune under all other circumstances. The Nomination Date for the Initial Target shall be the Effective Date. Date of acceptance of a Nomination Notice by Adaptimmune under this Section 5.3.2 shall constitute the Nomination Date in relation to all other Targets and HLAs notified under this Section 5.3.2.

5.3.3. Upon the Nomination Date, Adaptimmune shall immediately remove the Nominated Target from the Dataroom (if such Target is in the Dataroom), and thereafter, Adaptimmune shall not (a) work on or further develop any Therapy to the Nominated Target, including any HLA alleles associated with such Nominated Target except as provided in this Agreement; (b) license or collaborate with any Third Party in relation to the development of any Therapy to the Nominated Target; or (c) otherwise make available such Nominated Target to any Third Party for development of a Therapy to such Nominated Target. Adaptimmune warrants that all information regarding the Initial Target has been removed from the Dataroom on or before the Effective Date, and the Parties agree that the foregoing sentence applies to the Initial Target as of the Effective Date.

***Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

5.3.4. Adaptimmune may remove Targets from the Dataroom in its sole discretion at any time prior to receipt of a Nomination Notice, and may reject a Nomination Notice that names a Target, if (a) there is no freedom to operate with respect to such Target or TCR sequence meaning that use of such Target or TCR sequence would infringe the rights of a Third Party, (b) Adaptimmune has an agreement in principle to grant a licence to a Third Party as evidenced by the *** and the Third Party *** , (c) Adaptimmune has selected the Target to be the subject of an internal program as can be evidenced by ***

or in relation to which research work has actually started within Adaptimmune, in each case prior to the receipt of the Nomination Notice, or (d) Adaptimmune has agreed binding terms in relation to such Target with a Third Party. Any Target removed from the Dataroom or named in a Nomination Notice rejected by Adaptimmune in accordance with this Section 5.3.4 shall be deemed an “Invalid Target”. Adaptimmune shall not be liable for any claim by GSK arising out of removal of a Target from the Dataroom by Adaptimmune prior to receipt of a Nomination Notice. Any Nomination Notice received in relation to an Invalid Target shall be deemed rejected and Adaptimmune shall remove the Invalid Target from the Dataroom if not previously removed. GSK shall have the right to nominate a replacement Target (each, a “Replacement Target”) in lieu of the Invalid Target in the same manner as described in Section 5.3.2 until the later of either (i) expiration of the Dataroom Period, or (ii) six (6) months from GSK’s receipt of notice that a Nominated Target is an Invalid Target. For clarity, GSK may continue to nominate Replacement Targets under the terms of this Agreement when and if previously nominated Replacement Targets are deemed Invalid Targets and subject to the maximum of five (5) Target Programs under Section 5.1.

5.3.5. With respect to any Invalid Target described in Section 5.3.4(a) above, Adaptimmune agrees not to (a) work on or further develop any Therapy to the Invalid Target, including any of its HLA alleles associated with such Invalid Target; or (b) licence or collaborate with any Third Party in relation to the development of any Therapy to the Invalid Target, including any HLA alleles associated with such Invalid Target, in each case, for a period commencing on the date that the Nomination Notice specifying such Invalid Target was deemed invalid in accordance with Section 5.3.4(a) (or as relevant the date a Target is removed from the Dataroom), and ending on the latest to occur of either (i) *** from such date; or (ii) the *** of the Effective Date, in each case subject to Section 5.3.6 below.

5.3.6. Where any Invalid Target, with respect to which Adaptimmune rejected a Nomination Notice from GSK, subsequently becomes available for licence to GSK or any other Entity, Adaptimmune shall provide prompt written notice to the first Entity in time (which for purposes of this Section 5.3.6 includes GSK) that (a) previously nominated such Target; and (b) has any further right to request a licence to such Target. That Entity shall then have a thirty (30) day period to nominate the now available Target in accordance with the terms agreed between Adaptimmune and such Entity. After expiration of such thirty (30) day period, Adaptimmune shall offer the now available Target to the next

***Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

Entity in time that previously requested such Target and that Entity shall then have thirty (30) days to nominate the now available Target. This procedure shall continue for the next Entity in time using the same procedure as set out in this Section 5.3.6 until the earlier of an Entity taking a licence to such now available Target or all entities rejecting such Target.

5.3.7. Where any Nominated Target is accepted by Adaptimmune (excluding the Initial Target), the JSC shall have sixty (60) days (or such other reasonable period as may be necessary) after the Nomination Date to develop and approve the Development Plan for the applicable Target Program or HLA Program, and promptly thereafter Adaptimmune shall commence the work set forth in the Development Plan; provided, that Adaptimmune shall have no obligation to commence work under an agreed Development Plan until the earlier of (a) the *** of work under a Development Plan for the most recently agreed and active Collaboration Program; or (b) the date on which Adaptimmune has ***

. For the avoidance of doubt, the foregoing *** shall not apply to the conduct of the Initial Target Program, the Research Pool Program or the Second Target Program.

5.3.8. Notwithstanding the foregoing, Adaptimmune shall use Commercially Reasonable Efforts to conduct on-going Target validation work in accordance with its then current business plans in order to add new Targets to the Dataroom during the Dataroom Period. During the Dataroom Period Adaptimmune shall report to the JSC at each JSC meeting as to its progress with on-going Target validation work and the total number of Targets in the Dataroom at such time, and shall notify the JSC where any new Target is added to the Dataroom. This Section 5.3.8 shall not require Adaptimmune to provide any sequence information or any other additional information other than the type of information as is provided for other Targets in the Dataroom.

5.3.9. ***

***Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

5.3.10. In addition to GSK’s right to nominate a Target in accordance with Section 5.3.2 above, GSK shall also have the right to ask Adaptimmune to remove no more than one Target at a time from the Dataroom to allow GSK to conduct preliminary diligence on such Target for a period not to exceed sixty (60) days. Such request shall be made in writing and shall specify the relevant Target (“Pre-diligence Notice”). During the period of sixty (60) days from receipt of the Pre-diligence Notice, the provisions of (i) Section 5.3.3 shall apply to the notified Target and Adaptimmune shall remove such Target from the Dataroom, and (ii) Adaptimmune agrees not to licence or collaborate with any Third Party in relation to the development of any Therapy to the applicable Target, including any HLA alleles associated with such Target. The Pre-diligence Notice shall also be subject to Section 5.3.4 (as if the Target named in the Pre-diligence Notice was a Target named in a Nomination Notice) and GSK will be entitled to issue a Pre-diligence Notice in respect of a different Target should Section 5.3.4 apply. For clarity, Section 5.3.5 and Section 5.3.6 shall not apply to any Target specified in a Pre-diligence Notice, and preliminary diligence on any Target shall not include any right for GSK to research or develop any Engineered TCR to the applicable Target selected for preliminary diligence by GSK.

5.4. Research Licence. Commencing on the Effective Date, and solely to the extent that it is agreed in any Collaboration Program or Research Pool Program that GSK should conduct work under the applicable Development Plan or Research Pool Program, Adaptimmune shall grant and hereby grants to GSK a non-exclusive licence in the Territory under the Adaptimmune Background and Adaptimmune’s interests in Collaboration Program IP, to

***Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

the extent necessary for GSK’s performance of the Collaboration Program or Research Pool Program. The licence under this Section 5.4 shall expire on the earlier of (a) the date on which Adaptimmune rejects a Nomination Notice in accordance with Section 5.3.2; or (b) an exclusive licence being granted following exercise of the relevant Option, as applicable; or (c) expiration of the applicable Option Period without exercise of the Initial Program Option or Collaboration Program Option, as applicable; or (d) Completion of the Collaboration Program or Research Pool Program. The licence under this Section 5.4 shall be sub-licenseable to GSK’s Affiliates and subcontractors to the extent such Affiliates and subcontractors are performing any obligations under any Collaboration Program or the Research Pool Program.

5.5. Research Pool Restrictions. Commencing on the date of agreement of the Targets for inclusion in the Research Pool and ending on expiry of the earlier to occur of (a) expiration of the Second Target Nomination Period without GSK having nominated the Second Target; or (b) nomination of the Second Target from the Research Pool by GSK in accordance with Section 5.3.2, Adaptimmune agrees that it shall not (i) work on or further develop any Therapy to the Targets within the Research Pool, including any HLA alleles associated with such Targets except as provided in this Agreement; (ii) license or collaborate with any Third Party in relation to the development of any Therapy to the Targets within the Research Pool; or (iii) otherwise make available such Targets within the Research Pool to any Third Party for development of a Therapy to such Targets. Adaptimmune shall remove all information regarding the Targets within the Research Pool from the Dataroom upon selection thereof in accordance with Section 5.1.2. For clarity, Adaptimmune may in its discretion return information regarding the Targets within the Research Pool to the Dataroom (a) for all Targets in the Research Pool on expiration of the Second Target Nomination Period without GSK having nominated the Second Target; or (b) for the Targets from the Research Pool which have not been nominated following nomination of the Second Target from the Research Pool by GSK in accordance with Section 5.3.2.

6. Options; Licences

6.1. Adaptimmune shall grant and hereby grants to GSK, a series of exclusive options (each an “Option”) to obtain the exclusive licences on the terms set out in Section 6.6.

6.1.1. The Option in respect of the Initial Target Program shall commence on the Effective Date, and shall expire on the date that is the later to occur of either (i) ***

; (ii) ***

if GSK decides to ***

with respect to the Generation 1 Therapy; or (iii) *** GSK determines that *** with respect to the *** will either *** if such decision occurs *** (“Initial Target Program Option Period”). GSK shall have the right during such Initial Target Program Option Period to audit all subcontractors in the supply chain; provided, that if Adaptimmune’s contracts with such subcontractors do not permit GSK’s direct audit of their facilities, then Adaptimmune shall use all Commercially Reasonable Efforts to conduct the audit on GSK’s behalf and

provide all results of such audit to GSK reasonably promptly (and in each case to the extent permitted by the relevant sub-contracts). If GSK does not exercise the Option in respect of the Initial Target Program prior to expiration of the Initial Target Program Option Period then thereafter GSK shall have no right to develop and commercialize the Therapy or Licensed Product arising from the Initial Target Program. For the avoidance of doubt, if GSK does not exercise the Option *** , the Option ***

6.1.2. The Option in respect of the Second Target Program Option shall commence on the Nomination Date for the Second Target and shall expire (i) following *** of the documentation and Results after completion of work for *** ; and (ii) on the date that is *** for any Therapy subject to the Second Target Program (“Second Target Program Option Period”).

. If GSK does not exercise the Option in respect of the Second Target Program prior to expiration of the Second Target Program Option Period then thereafter GSK shall have no right to develop and commercialize the Therapy or Licensed Product arising from the Second Target Program. For clarity no Option is granted in relation to the two (2) other Targets forming part of the Research Pool and which are not nominated in accordance with Section 5.3.

6.1.3. The Option in respect of all other Collaboration Programs shall commence on a Collaboration Program-by-Collaboration Program basis on the Nomination Date for the relevant Target or HLA and shall expire (i) following *** of the documentation and Results after completion of work for *** ; and (ii) on the date that is ***

for any Therapy subject to the applicable Collaboration Program (“Collaboration Program Option Period”). For clarity, if the ***

. If GSK does not exercise the Option in respect of any Collaboration Program (other than the Initial Target Program and Second Target Program) prior to expiration of the Collaboration Program Option Period then thereafter GSK shall have no right to develop and commercialize the Therapy or Licensed Product arising from the applicable Collaboration Program to which the Option relates.

6.2. GSK may exercise an Option at any time during the periods set out in Section 6.1 above by provision of written notice to Adaptimmune specifying the Initial Target Program, Second Target Program or other Collaboration Program in relation to which the Option is being exercised (“Option Notice”). On receipt of the Option Notice by Adaptimmune and payment of the relevant Milestone Fee, Adaptimmune shall grant, and hereby

***Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

grants, to GSK the exclusive licence on the terms set out in Section 6.6 with respect to such Initial Target Program, Second Target Program or other Collaboration Program.

6.3. On a Collaboration Program-by-Collaboration Program basis and Target-by-Target basis and during the Initial Target Program Option Period, Second Target Program Option Period or Collaboration Program Option Period (collectively, and as the context requires, the “Option Periods”), as applicable, Adaptimmune shall not (a) independently or with, or on behalf of, a Third Party, conduct any research, development or commercialisation activities on any Therapy directed to the Nominated Target subject to such Collaboration Program or Licensed Product; or (b) license any Third Party under its rights in the Collaboration Program IP, Adaptimmune Background or Joint Background to manufacture, use, sell or supply any Therapy directed to the Nominated Target subject to such Collaboration Program or Licensed Product. ***

; or (ii) Adaptimmune licenses its Intellectual Property Rights to a Third Party in relation to the development of Therapies or TCRs to Targets other than the Nominated Target; or (iii) Adaptimmune licenses its Intellectual Property Rights to a Third Party to enable such Third Party to carry out specific research projects intended to improve or enhance the Adaptimmune Background and which are not specific to any Nominated Target. For clarity any research or development licence agreement with a Third Party under Section 6.3(iii) shall not include any licence under Adaptimmune Background, Joint Background or Collaboration Program IP to manufacture, sell, supply, use, import or commercialise any Therapy or Licensed Product arising out of a Collaboration Program.

6.4. For the avoidance of any doubt and save as explicitly otherwise provided in Section 6.6, no licence is granted under this Agreement (including under any exercise of an Option or the licenses granted under Section 6.6) to GSK under Adaptimmune Background or Collaboration Program IP in relation to any product that contains Soluble TCRs.

6.5. During the term of this Agreement, Adaptimmune shall inform GSK where it reasonably determines that it may be unable to continue to fund any Collaboration Program or Research Pool Program, including payments to subcontractors, or where it considers that it will have insufficient funding to employ the FTEs required by Adaptimmune to Complete any Collaboration Program or Research Pool Program within the timescales agreed in the relevant Development Plan that are planned to be conducted in the next four (4) months. Such determination shall be made by assessing Adaptimmune’s then-current cash burn rate and cash flow forecasts. In particular, Adaptimmune’s Alliance Manager shall report to the JSC at each JSC meeting as to whether, following a discussion with the CEO of Adaptimmune, the insufficiencies described in the foregoing sentence exist. Following disclosure of such concerns, GSK may request a meeting between an appropriate and senior individual within GSK and Adaptimmune’s CEO to discuss potential insufficiencies and any potential resolutions or mitigating factors which may exist. Any meeting (which will be by telephone call unless otherwise agreed) shall be held promptly and Adaptimmune will answer any reasonable questions raised in such meeting. Nothing in this Section 6.5 shall be construed to require Adaptimmune to breach any regulatory requirements or rules of any relevant stock exchange on which Adaptimmune or any of its Affiliates may at any time be listed.

6.6. Licence Terms.

6.6.1. Commencing upon GSK’s exercise of an Option as described in Section 6.2, Adaptimmune shall grant and hereby grants to GSK the following licenses:

(a) an exclusive license under Adaptimmune’s interests in and to Collaboration Program IP and Joint Background to make, have made, import, use, offer for sale, and sell Licensed Products arising from the applicable Collaboration Program in the Field in the Territory. Each such license shall continue for the applicable Royalty Term, unless earlier terminated pursuant to Article 13;

(b) an exclusive license under the Adaptimmune Background solely to the extent it is necessary for GSK to make, have made, import, use, offer for sale, and sell Licensed Products in each case as arising from the applicable Collaboration Program in the Field in the Territory. Each such license shall continue until the earlier to occur of (i) the date on which such license is no longer necessary for GSK to make, have made, import, use, offer for sale, and sell Licensed Products in the Field in the Territory; or (ii) expiration of the applicable Royalty Term, unless earlier terminated pursuant to Article 13;

6.6.2. Each licence granted in accordance with Section 6.6 is separate and independent from any other licence granted in accordance with this Agreement.

6.7. The licences under Section 6.6 shall not include any rights to (a) create new or different Engineered TCRs to a different Target other than the applicable Nominated Target; or (b) to modify the variable domain of the Engineered TCR (including to introduce new or different mutations into the variable domain); provided that it shall not be a breach of this Section 6.7(a) if any Licensed Product that is directed primarily at the applicable Nominated Target additionally binds to a Target other than the Nominated Target.

6.8. The licences under Section 6.6 include the right to sub-licence with the prior written consent of Adaptimmune, such consent not to be unreasonably withheld, except, that consent shall not be required as follows:

6.8.1. GSK may use contract research organizations to perform portions of the development of the Licensed Products to the extent consistent with its normal business practices and in all cases consistent with Section 3.8 above;

6.8.2. GSK may engage reasonably qualified Third Parties to distribute and sell the Licensed Products to the extent such arrangements are commercially reasonable throughout the Territory and in all cases consistent with Section 3.8 above;

6.8.3. GSK may use Third Parties, including contract manufacturers, to manufacture, label and package the Licensed Products provided such use is in all cases consistent with Section 3.8 above; and

6.8.4. GSK may sub-license any of its rights to Affiliates.

GSK shall notify Adaptimmune within thirty (30) days of execution of any sub-licence agreement and, except with respect to sublicences to Affiliates, shall provide a redacted copy (in which commercial terms or terms not relevant to compliance with the terms of this Agreement shall be redacted) of such sub-licence agreement to Adaptimmune. Where any Affiliate is sub-licensed by GSK, GSK shall procure that such Affiliate agrees to comply with the applicable terms of this Agreement including Sections 6.8, 6.9, 6.14, 8.3 and 13.8 and Articles 7, 9, 10, and 14. GSK shall remain responsible for any acts or omissions of its sub-licensees including to the extent such acts or omissions result in a breach of the terms of this Agreement.

6.9. Save in relation to the terms of any Agreement agreed by Adaptimmune prior to the Effective Date and provided to GSK in the Due Diligence Dataroom, each Party will include binding provisions in all sub-licences granted in accordance with Section 6.8 or 3.8 providing that if the sub-licensee or any of sub-licensees’ Affiliates ***

6.10. Post-Option Exercise Responsibilities.

6.10.1. Following commencement of each licence as provided in Section 6.6, GSK shall use Commercially Reasonable Efforts to further develop, manufacture, sell and supply Licensed Products within the Territory with a view to obtaining Regulatory Approval for at least one Licensed Product from each Collaboration Program as soon as reasonably possible. GSK shall comply with all Applicable Laws including requirements of GMP and GCP in relation to any manufacture, development, sale or supply of Licensed Products. GSK shall be solely responsible for all activities relating to the manufacture, development, sale and supply of Licensed Products and shall have sole and final decision-making authority with respect thereto.

6.10.2. GSK will submit reports to Adaptimmune on *** basis, commencing six months after GSK exercises the first Option, as applicable, to update Adaptimmune, in reasonable detail, on the current progress and status of the conduct of material development activities with respect to the Licensed Products including Clinical Trial progress. Each Party shall provide details of any SUSARs as soon as reasonably possible after it becomes aware of such SUSARs and in each case to the extent that such SUSAR relates in the case of GSK to any Licensed Product; and in the case of Adaptimmune to any Engineered TCRs (to the extent Adaptimmune is able to provide such information without breaching any Third Party obligation). Nothing in this Section 6.10.2 will obligate GSK to disclose confidential information to

***Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

Adaptimmune regarding a proprietary compound or product of GSK or a Third Party. Adaptimmune may ask clarification questions following receipt of reports and GSK (via its Alliance Manager or otherwise) will provide answers within reasonable timescales to such clarification questions.

6.11. Technology Transfer; Regulatory Assistance.

6.11.1. Adaptimmune shall transfer and deliver (or provide access) to GSK all Results arising out of such Collaboration Program, Initial Target Program or the Second Target Program as relevant to the extent GSK does not already have access to such Results and to the extent such Results are in a tangible form, together with all materials set forth on Schedule 7 (if applicable) in a manner that allows for the orderly transition of Licensed Products to GSK following GSK’s exercise of the Option relating to such Collaboration Program, Initial Target Program or Second Target Program. The JSC, in collaboration with the relevant JPT and JMC (if applicable) or the Parties (to the extent the JSC is no longer in existence for such Collaboration Program) shall develop and complete a detailed technology transfer plan to implement the activities set forth in the foregoing sentence within fifteen (15) Business Days after exercise of the relevant Option; provided, that such technology transfer shall be completed no later than sixty (60) days after GSK exercises an Option. Such Results shall be provided in the form agreed in the Development Plan or as otherwise agreed between the Parties. Any data package intended to be submitted to a Regulatory Authority with an IND filing shall meet all applicable Regulatory Authority guidelines. Adaptimmune shall use Commercially Reasonable Efforts to transfer the Results and materials on Schedule 7 (if applicable) in a format that is compliant with Applicable Laws; provided that, if such format is not compliant with Applicable Laws, then GSK shall inform Adaptimmune of such insufficiency and Adaptimmune shall use Commercially Reasonable Efforts to correct such insufficiency reasonably promptly thereafter. The details of any additional materials or documentation that may be reasonably required by GSK to further develop, manufacture, register or sell Licensed Products, shall be determined by the JSC including as relevant the timing of provision of any such additional documentation. The JSC shall also determine the amount of reasonable technical assistance and training initially required from Adaptimmune, at Adaptimmune’s expense, to GSK’s personnel with respect to Results and the materials set forth in Schedule 7 (if applicable) to enable GSK to comply with its diligence obligations under Section 6.10.1. Such initial technology assistance and training shall be provided promptly as reasonably required and determined by the JSC, and in furtherance of the JSC’s determination, Adaptimmune shall make available suitably qualified and experienced resources to provide such technical assistance and training. Thereafter, GSK may request up to four (4) meetings per Year (which may be held by teleconference or video conference). ***

and to the extent that any technical assistance and training ***

. For the avoidance of doubt, the foregoing

technology transfer support provided by Adaptimmune shall not include any retesting or other scientific analysis of Results provided by Adaptimmune.

6.11.2. Where it is required or desirable that Adaptimmune attend meetings (either after exercise of an Option or during the applicable Option Period) between GSK and Regulatory Authorities to discuss matters for which Adaptimmune was responsible, including any End of Phase 2 meeting where the Phase 1/2 Data Packages from the Initial Target Program may be discussed, or any meeting at which Results in support of an IND filing from any other Collaboration Program will be discussed, Adaptimmune shall participate in such meetings with GSK. In each case, the Parties shall meet in advance of such regulatory meeting to agree objectives of the meeting, questions to be presented and answered, information and documentation to be provided, and strategy and roles of each Party at the meeting. Adaptimmune shall inform GSK immediately if, after exercise of an Option, any Regulatory Authority communicates with it instead of GSK with respect to any Licensed Products or Therapies arising from the applicable Collaboration Program, and shall not respond to such communications except to inform the Regulatory Authority that GSK is the Party responsible for such Therapy or Licensed Product.

6.12. On a Collaboration Program-by-Collaboration Program basis, commencing on the date such Collaboration Program commences and expiring upon the earlier of termination of the Collaboration Program, Completion of the Collaboration Program, or termination of this Agreement, GSK hereby grants to Adaptimmune a non-exclusive, royalty-free licence in the Territory, with the right to grant sublicences (subject to Section 3.8), under GSK Background that GSK determines in its sole discretion is necessary for the conduct of the Collaboration Program solely to permit Adaptimmune to conduct its activities with respect to such Collaboration Program as contemplated under the applicable Development Plans in accordance with the terms of this Agreement.

6.13. During the Term, GSK also grants to Adaptimmune an option to negotiate a non-exclusive, worldwide, royalty-bearing licence under the GSK Background to make, have made, use, sell, offer for sale and import Therapies other than Licensed Products. Adaptimmune shall be entitled to exercise such option by notice in writing to GSK. GSK shall notify Adaptimmune of its decision whether or not to negotiate the terms of such license within ninety (90) days and GSK may decline to negotiate for any reason or no reason in its sole discretion. Where GSK is prepared to negotiate the terms of a licence, the Parties shall have a period of sixty (60) Business Days to negotiate using good faith efforts; provided, that if the Parties cannot agree terms within such sixty (60) Business Day period, then GSK shall have no further obligation to negotiate any terms with Adaptimmune with respect to a license to GSK Background. For the avoidance of doubt, GSK shall have no obligation to disclose any confidential GSK Background to Adaptimmune, and is under no obligation to agree to negotiate with Adaptimmune, in either case, in furtherance of this Section 6.16.

6.14. During the Term, GSK agrees that (a) it will not ***

7.3.6. Prior to permitting any patent application or patent relating to any Collaboration Program IP or Joint Background to lapse, the Party that is first responsible for prosecution under this Section 7.3 (the “Prosecuting Party”) will provide sixty (60) days written notice to the non-Prosecuting Party (“Lapse Notice”). The non-Prosecuting Party shall be entitled to take over the filing, maintenance and prosecution of such notified patent or patent application on providing written notice to the Prosecuting Party within a period of thirty (30) days from receipt of Lapse Notice, at the non-Prosecuting Party’s sole discretion. Where such notice is provided, the Prosecuting Party shall provide all reasonable assistance as soon as possible following receipt of notice from the non-Prosecuting Party to transfer the filing, maintenance and prosecution of such notified patent or patent application to the non-Prosecuting Party. For the avoidance of doubt, the cooperation and review provisions of Section 7.3.2 or 7.3.3 will no longer apply to the filing, maintenance and prosecution of the applicable patents and patent applications. Where the non-Prosecuting Party indicates it does not wish to take over the filing, maintenance or prosecution of any notified patent or patent application or fails to respond within a period of thirty (30) days from receipt of Lapse Notice, the Prosecuting Party shall be entitled to permit the patent or patent application to lapse. ***

that it does not intend to prosecute a particular Action, (ii) within thirty (30) days after notice of Infringement the Enforcing Party has not commenced any such Action, or (iii) if the Enforcing Party thereafter ceases diligently to pursue such Action, then the non-Enforcing Party shall have the right, at its own expense, upon notice to the Enforcing Party to take appropriate action to address such Infringement, including by initiating its own Action or taking over prosecution of any Action initiated by the Enforcing Party. In such event, the non-Enforcing Party shall keep the Enforcing Party fully informed about such Action. The non-Enforcing Party shall not take any position with respect to such Action in any way that is reasonably likely to directly and adversely affect the scope, validity or enforceability of the Intellectual Property Rights that are the subject of such Action, or compromise or settle such Action, without the Enforcing Party’s prior written consent, which consent shall not be unreasonably withheld. The non-Enforcing Party’s right to enforcement as described in this Section 7.4.4 with respect to an Infringement described in Section 7.4.1(c) is applicable solely to the extent permitted by Applicable Law. In the event that the Enforcing Party has informed the non-Enforcing Party that it is not proceeding with an Action on the advice of competent counsel, and the non-Enforcing Party opts to proceed with such Action, then the non-Enforcing Party will, at the Enforcing Party’s request, execute an agreement confirming that the decision to sue was made despite the Enforcing Party’s objection and the non-Enforcing Party shall indemnify, defend and hold harmless the Enforcing Party and its Affiliates for all Losses arising out of Claims suffered by the Enforcing Party as a result of such suit. ***

7.5. The Party responsible for any Action under Sections 7.4.2 and 7.4.3 shall also be entitled to defend any counterclaim proceedings for invalidity or revocation of the relevant patent in any Action. The other Party shall be entitled to its own legal representation in relation to such Action and any counterclaim and the Party responsible for the Action shall where possible take into account reasonable comments or requests made by the other Party in relation to the defence of any counterclaim for invalidity or revocation.

7.6. The Parties shall cooperate and provide all reasonable assistance, subject to the payment of all reasonable expenses and costs, to each other with respect to any Action described in Section 7.3.8 above. Upon the reasonable request of the Party instituting such Action, the other Party shall join such Action and shall be represented using counsel of its own choice, at the requesting Party’s expense; provided, that if *** or *** has informed the other Party that it would not proceed with such Action on the opinion of competent counsel, as provided in Sections 7.4.2 and 7.4.3, the other Party may not require *** to join such Action unless legally required to do so. The provision of assistance under this Section 7.6 shall include reasonable assistance as may be required by either Party to determine which patent applications or patents should be used in any Action or should be submitted to a Third Party that files a Biosimilar Application as required by the BPC&I Act. Once any patent application or patent has been identified or agreed to be litigated with the Third Party filing the Biosimilar Application, the Prosecuting Party for such patent application or patent shall provide all reasonable assistance (including access to its internal files such as prosecution files and laboratory notebooks) as may be required to ensure that such patent application or patent is valid, has been filed in accordance with the rules and regulations of the relevant patent office and that there is no reason which might suggest that any identified patent or patent application could not or should not be used in any Action. ***

7.7. Defence of Infringement Claims.

7.7.1. Each Party shall promptly notify the other Party in writing of any allegation by a Third Party in the Territory that the making, having made, using, selling or offering for sale or importing of any Licensed Product, or the conduct of any activities under this Agreement infringe or misappropriate or may infringe or misappropriate the Intellectual Property Rights of such Third Party (a “Third Party Infringement Claim”). The Patent Liaisons shall discuss which Party shall defend the Third Party Infringement Claim, and absent mutual agreement otherwise, each Party shall have the right to control the defence of any such Third Party Infringement Claim brought against it in the Territory, by counsel of its own choice. If a Third Party Infringement Claim is brought against one Party (the “Defending Party”) but not the other Party, the non-Defending Party shall have the right, at its own expense, to be represented in such Third Party Infringement Claim by counsel of its own choice, at its own expense.

7.7.2. The Patent Liaison for the Defending Party shall keep the Patent Liaison for the other Party reasonably informed of all material developments in connection with any Third Party Infringement Claim. Each Defending Party

***Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

agrees to provide the other Party’s Patent Liaison with copies of all pleadings filed in any suit or proceeding relating to such Third Party Infringement Claim. The Defending Party may enter into a settlement or compromise of any Third Party Infringement Claim; provided, that if such settlement or compromise would admit liability on the part of the non-Defending Party or any of its Affiliates or would otherwise have a material adverse effect on the rights or interests of the non-Defending Party or its Affiliates, the Defending Party shall not enter into such settlement or compromise without the prior written consent of the non-Defending Party. In the event a proposed settlement involves obtaining a license under Third Party Intellectual Property Rights, the provisions of Section 9.6 shall apply. Notwithstanding the foregoing, as between the Parties, solely to the extent permitted under Section 7.3.8 and 7.5 above, the Parties shall have the right to determine whether to assert any counterclaim under any patent applications or patents comprising Collaboration Program IP and Joint Background and to control any such counterclaim, and to control the defence of any matters involving the validity or enforceability of any such patent applications or patents, including the right to make substantive and procedural decisions relating to any such counterclaim or defence and settle, compromise or dispose of any such counterclaim or defence.

7.8. Save as otherwise explicitly provided in accordance with this Agreement, GSK will retain control and all decision-making regarding filing, prosecution and maintenance of all GSK Background, at GSK’s sole cost during the Term. GSK shall have sole discretion in relation to any Action against an Infringement of GSK Background by a Third Party.

7.9. Nothing in this Agreement shall assign any Adaptimmune Background to GSK. Nothing in this Agreement shall assign any GSK Background to Adaptimmune.

7.10. CREATE Act. It is the intention of the Parties that this Agreement is a “joint research agreement” as that phrase is defined in Public Law 108-53 (the “Create Act”). In the event that either Party to this Agreement intends to overcome a rejection of a claimed invention within the ***

8. Consideration

8.1. In partial consideration for the rights granted to GSK under this Agreement, GSK shall pay to Adaptimmune a non-refundable, non-creditable upfront payment of £25,000,000.00 (twenty five million pounds sterling). Such payment shall be payable by wire transfer of immediately available funds in accordance with wire transfer instructions of Adaptimmune provided in writing to GSK on or prior to the Effective Date. Such payment shall be made within *** after GSK’s receipt of an invoice from Adaptimmune provided on or after the Effective Date, which invoice shall be sent in accordance with the instructions on Schedule 6.

8.2. Subject to the terms and conditions set forth in Schedule 2 and this Section 8.2, GSK shall pay to Adaptimmune the Milestone Fees. Such Milestone Fees shall be payable by GSK whether the relevant milestone is achieved by Adaptimmune, Adaptimmune’s Affiliates, GSK, GSK’s Affiliates or GSK’s or its Affiliates’ sub-licensees. Each Party shall procure that it has adequate reporting obligations in place between Affiliates and sub-licensees to ensure compliance with this Section 8.2. A Party achieving a milestone as set forth in Schedule 2 shall notify the other Party in writing promptly, but in no event later than five (5) Business Days after such Party becomes aware of each achievement of each milestone that triggers a payment. Each Milestone Fee payable for an achieved Milestone as set forth in Schedule 2 will be due *** from the date of receipt of an invoice from Adaptimmune, which invoice shall be provided on or after the date that GSK notifies Adaptimmune or Adaptimmune notifies GSK as relevant, in writing, of such achievement or Adaptimmune otherwise becomes aware of such achievement and such achievement is not disputed by GSK. In relation to any milestones to be achieved by Adaptimmune, there shall be no obligation on Adaptimmune to proceed to the next Project Phase until it has received payment of the relevant Milestone Fee following achievement of such milestone.

8.3. Subject to the terms and conditions set forth in Schedule 2 and this Section 8.3, GSK shall pay to Adaptimmune the Sales Milestone Fees (as defined in Schedule 2). Such Sales Milestone Fees shall be payable by GSK based on the aggregate Net Sales made by GSK, GSK’s Affiliates or GSK’s or its Affiliates’ sub-licensees and GSK shall procure that it has reporting obligations in place between Affiliates and sub-licensees (including Affiliates’ sub-licensees) to ensure compliance with this Section 8.3. Each Sales Milestone Fee payable for an achieved Sales Milestone as set forth in Schedule 2 will be due *** from the date of receipt of an invoice from Adaptimmune, which invoice shall be provided on or after the date that GSK notifies Adaptimmune, in writing, of such achievement or Adaptimmune otherwise becomes aware of such achievement and such achievement is not in dispute by GSK.

8.4. Any tax paid or required to be withheld by GSK for the benefit of Adaptimmune on account of any Royalty or other payments payable to Adaptimmune under this Agreement shall be deducted from the amount of Royalty or other payments otherwise due. GSK shall secure and send to Adaptimmune proof of any such taxes withheld and paid by GSK for the benefit of Adaptimmune, and shall, at Adaptimmune’s request, provide reasonable and prompt assistance to Adaptimmune in recovering such taxes.

8.5. If any undisputed payment due by GSK to Adaptimmune pursuant to this Agreement is overdue then GSK shall pay interest thereon at an annual rate equal to *** on the due date of payment (or on the next Business Day if the due date is not a Business Day)

***Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

***, such interest to be pro-rated for the number of days from the date upon which payment of such sum became due until payment thereof in full together with such interest; provided, that in no event shall such rate exceed the maximum legal annual interest rate. The payment of such interest shall not limit Adaptimmune from exercising any other rights it may have as a consequence of the lateness of any payment. Where the late payment is caused by Adaptimmune, including for reasons such as failure to communicate in a timely manner changes to bank details, or failure to respond to communications from GSK regarding the interpretation or dispute of the terms of such payment, then no interest will be payable by GSK.

8.6. All payments to be made by GSK to Adaptimmune under this Agreement shall be paid in pounds sterling by bank wire transfer of immediately available funds in accordance with the wire transfer instructions set forth in Schedule 6. Adaptimmune shall issue any invoices under this Agreement in accordance with the instructions set out in Schedule 6.

9. Notification and Royalty Payments

9.1. As further consideration for the rights granted to GSK under this Agreement, GSK shall pay Adaptimmune the Royalty set forth below on a calendar quarterly basis during the Royalty Term, and otherwise in accordance with the provisions of this Article 9:

Cumulative Annual Net Sales per Calendar Year		Amount of Royalty payable (% of Net Sales)
On annual aggregate Net Sales up to and including £***		***
On annual aggregate Net Sales >* up to and including £*		***
On annual aggregate Net Sales >£* up to and including £*		***
On annual aggregate Net Sales ***		***

9.2. Royalty Term.

9.2.1. Subject to the provisions of this Article 9, GSK’s obligation to pay the Royalty shall be calculated on a country-by-country and Licensed Product-by-Licensed Product basis, in those countries of the Territory in which there is a Valid Claim that, either (i) falls within any Joint Collaboration IP Covering ***

of any Licensed Product or any part of the Licensed Product contained therein in the country of sale; or (ii) but for the licenses granted to GSK, would be infringed by the ***

of any Licensed Product or any part of the Licensed Product contained therein in the country of sale. GSK’s obligation to pay the

***Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

Royalty with respect to any Licensed Product shall commence upon the First Commercial Sale of such Licensed Product in a country, and shall expire on the later of (i) the expiration of the last Valid Claim Covering ***

in the country of sale; and (ii) the date that is ten (10) years from the First Commercial Sale of such Licensed Product in such country (the “Royalty Term”). To the extent that any Licensed Product is sold in any country prior to First Commercial Sale (such as for compassionate use or on a named patient sales basis), Net Sales from such sales shall be accrued as from the time of sale and Royalties on such Net Sales shall become due in the quarter after First Commercial Sale in accordance with Section 9.14.

9.2.2. For clarity, once the Royalty Term expires in any country, Net Sales in such country will not be included in the calculation of Cumulative Annual Net Sales in a Calendar Year as set forth in the table in Section 9.1 for purposes of determining the applicable royalty rate. By way of illustration only, if global Net Sales in a Calendar Year are £*** million, and £*** million of such global Net Sales are in countries where the Royalty Term has expired, then the Cumulative Annual Net Sales in a Calendar Year shall be £*** million and not £*** million.

9.2.3. If, on a country-by-country and Licensed Product-by-Licensed Product basis, the only Valid Claim Covering a Licensed Product is a claim of any pending patent application within the Collaboration Program IP or Joint Background covering *** of such Licensed Product (a “Pending Claim”), then the following shall apply with respect to payment of the Royalty on Net Sales of such Licensed Product:

(a) ***

, then GSK will pay *** percent (***%) of the applicable Royalty that would otherwise be due under Section 9.1 to Adaptimmune for so long as there is a Pending Claim Covering the ***

of the applicable Licensed Product. The rate of Royalty payable to Adaptimmune shall revert to the full Royalty as set out in Section 9.1 with effect from the date of issue of the Pending Claim until the end of the applicable Royalty Term, subject to any reductions as set forth in Sections 9.3, 9.5 or 9.6, as applicable during such Royalty Term. In addition, GSK ***

9.3. On a country-by-country and Licensed Product-by-Licensed Product basis, if, at any time during the Royalty Term, either no Valid Claim exists or all Valid Claims Covering the *** have expired, and Adaptimmune has maintained, at the time of sale of the applicable Licensed Product, Confidential Information as documented in written records that covers the *** of the Licensed Product, then GSK shall pay Adaptimmune a Royalty on Net Sales of such Licensed Product at a rate that is reduced by *** percent (***%) of the applicable Royalty rates set forth in Section 9.1.

9.4. Upon expiration of the applicable Royalty Term, the licenses granted to GSK under Section 6.6 shall become fully paid-up, royalty-free, perpetual licenses to make, have made, use, sell, offer for sale and import the applicable Licensed Product in the Field in the applicable country of the Territory.

9.5. The Royalty (as adjusted in accordance with Section 9.3) payable in relation to any Licensed Product on a country-by-country basis shall also be reduced by a further *** where any Biosimilar Product is sold in the relevant country ***

9.6. ***

***Portions of this page have been omitted pursuant to a request for Confidential Treatment and filed separately with the Commission.

9.7. With respect to sales of the Licensed Product invoiced in pounds sterling, the Net Sales and the amounts due hereunder will be expressed in pounds sterling. With respect to sales of the Licensed Product invoiced in a currency other than pounds sterling, the Net Sales and amounts due hereunder will be reported in pounds sterling, calculated using the average exchange rates as calculated and utilized by GSK’s group reporting system on a customary basis and published accounts for its own purposes. As of the Effective Date, the method utilized by GSK’s group reporting system uses spot exchange rates sourced from Reuters/Bloomberg. Such conversion shall be made as part of the quarterly reporting of Net Sales in the relevant accounts of GSK, GSK’s Affiliates or their sub-licensees.

9.8. Until the expiration of all applicable Royalty Terms, GSK will provide a report to Adaptimmune within sixty (60) days after each calendar quarter (“Royalty Report”), with the first report due within sixty (60) days after the expiry of the calendar quarter in which the First Commercial Sale of any Licensed Product by GSK or its Affiliates or their sub-licensees occurs. The Royalty Report shall include reasonable detail as available including: (i) the total Net Sales for each Licensed Product on a country-by-country basis; and (ii) a calculation of the amount of Royalty due on such Net Sales for each Licensed Product on a country-by-country basis. Concurrent with the delivery of each such Royalty Report, GSK shall make the Royalty payment due to Adaptimmune for the calendar quarter covered by such Royalty Report.

9.9. GSK or its Affiliates and their sub-licensees shall keep and maintain complete and accurate records of sales of Licensed Products in sufficient detail to allow Adaptimmune to confirm the accuracy of Royalties and Sales Milestones (as defined in Schedule 2) paid hereunder for a period of thirty-six (36) months ***

from the end of the calendar quarter or other period covered by such payment. For illustrative purposes only, records relating to Royalties paid for the calendar quarter January 2015 through March 2015 shall be kept by GSK through March 2018. Adaptimmune shall have the right during such three (3) year period to appoint an independent auditor reasonably acceptable to GSK to audit the records of GSK and/or any Affiliates and/or their sub-licensees for the purpose of verifying Royalty Reports provided by GSK. Such audit right shall not be exercised by Adaptimmune more than once in any Year and the records for a twelve (12) month period may not be audited more than once. GSK shall make its records available for audit by such independent auditor during regular business hours at such place or places where such records are customarily kept, upon sixty (60) days written notice from Adaptimmune. All records made available for audit shall be deemed to be Confidential Information of GSK. The results of each audit, if any, shall be binding on both Parties absent manifest error or fraud. GSK shall use reasonable efforts to require its Affiliates and any sub-licensees of Affiliates or GSK that sell the Licensed Products to permit Adaptimmune’s auditor access to records of such Affiliates and sub-licensees at the

Collaboration Program IP outside the Agreement as provided herein. The Party owning the Results, Joint Background or the Collaboration Program IP in Results shall be deemed to be the disclosing Party and the other Party shall be obliged to keep such Results, Collaboration Program IP and Joint Background confidential in accordance with this Section 10.1. The foregoing obligations of confidentiality will not apply to the extent that it can be established by the receiving Party that such Confidential Information:

10.1.1. was in the lawful knowledge and possession of the receiving Party prior to the time it was disclosed to, or learned by, the receiving Party, or was otherwise developed independently by the receiving Party, as evidenced by written records kept in the ordinary course of business, or other documentary proof of actual knowledge by the receiving Party;

10.1.2. was generally available to the public or otherwise part of the public domain at the time of its disclosure to the receiving Party;

10.1.3. became generally available to the public or otherwise part of the public domain after its disclosure and other than through any act or omission of the receiving Party in breach of this Agreement; or

10.1.4. was disclosed to the receiving Party, other than under an obligation of confidentiality, by a Third Party who had no obligation to the disclosing Party not to disclose such information to others.

10.2. The Parties may provide the Confidential Information to such of its officers, employees, representatives and subcontractors who reasonably require access to it for the purpose of fulfilling the receiving Party’s obligations or exercising its rights under this Agreement provided that before any of the disclosing Party’s Confidential Information is disclosed to them, they are made aware of its confidential nature and that they are under a legally-binding obligation to the receiving Party to treat that Confidential Information in the strictest confidence in accordance with the terms of this Agreement. For clarity, such disclosures may be made in the furtherance of, inter alia, (i) the performance of its obligations or exercise of rights granted or reserved in this Agreement; (ii) to the extent such disclosure is reasonably necessary in filing or prosecuting patent, copyright and trademark applications, prosecuting or defending litigation, obtaining Regulatory Approvals, conducting pre-clinical activities or Clinical Trials, marketing Licensed Products, or otherwise required by Applicable Laws; provided, that if a receiving Party is required by Applicable Law to make any such disclosure of a disclosing Party’s Confidential Information it shall, except where impracticable for necessary disclosures, for example in the event of medical emergency, give reasonable advance notice to the disclosing Party of such disclosure requirement and, except to the extent inappropriate in the case of patent applications, shall use its reasonable efforts to secure confidential treatment of such Confidential Information required to be disclosed.

10.3. The Parties may disclose the Confidential Information to Affiliates, existing or prospective advisors, shareholders, investors, collaborators, sublicensees, partners or joint ventures, in each case under appropriate confidentiality provisions substantially equivalent to those of this Agreement in furtherance of their activities under this Agreement. Further, a Party may disclose Confidential Information to Third Parties in connection with (i) a merger, consolidation or similar transaction by such Party, (ii) the

sale of all or substantially all of the assets of such Party to which this Agreement relates, or (iii) as required by rules of any stock exchange on which the securities of a Party are traded or as part of a listing of the securities of a Party on any stock exchange, in the case of (i) and (ii) under appropriate confidentiality provisions substantially equivalent to those of this Agreement. In each of the above authorized disclosures, the Receiving Party shall remain responsible for any failure by any person who receives the Confidential Information pursuant to this Section 10.3 to treat such Confidential Information as required under this Article 10.

10.4. Both Parties shall keep the terms of this Agreement confidential and such terms shall be treated as Confidential Information in accordance with this Article 10, except that Adaptimmune may (a) issue a public announcement of the execution of this Agreement in the form mutually agreed by the Parties and as set out in Schedule 9; (b) disclose the content of the Agreement to existing or prospective advisors, shareholders and investors or (c) as necessary as required by rules of any stock exchange or as part of any listing of the securities of Adaptimmune on any stock exchange. Adaptimmune may also issue public announcements of the achievement of each Milestone for each Licensed Product as set out in Schedule 2, with the prior review of GSK. Neither Party will use the other’s name or logo in any press release or product advertising, or for any other promotional purpose, without first obtaining the other’s written consent and entering into appropriate trademark or housemark licenses, as applicable. Neither Party will, without the prior written consent of the other Party, issue any public announcement or press release relating to this Agreement or the terms of this Agreement. Each Party shall provide the other with an advance copy of any such public announcement at least seven (7) days prior to its scheduled release; provided, that if the Party proposing such public announcement cannot provide the reviewing Party with seven (7) days notice due to extraordinary circumstances, such Party will use reasonable efforts to provide the reviewing Party with the proposed public statement for comment at least forty-eight (48) hours before release. Nothing in this Section 10.4 shall prevent any press release or announcement required in accordance with any regulatory requirement or stock exchange requirement.

10.5. After exercise of the applicable Option, GSK or its Affiliates shall have the right to make disclosures pertaining to Licensed Products in scientific journals or other publications, and at scientific conferences. Prior written consent from Adaptimmune will be required where any disclosure in scientific journals or other publications includes any Confidential Information comprised within Adaptimmune Background and which is not specific to the Licensed Product. GSK will reasonably endeavour to provide Adaptimmune with no less than thirty (30) calendar days to review the contents of any such proposed disclosure. Within such thirty (30) days, Adaptimmune may request that any such Confidential Information is removed from the proposed disclosure and GSK shall remove such Confidential Information prior to any disclosure. Adaptimmune shall have the right to make disclosures pertaining to the Adaptimmune Background; provided that such disclosure or presentation shall not contain any Confidential Information of GSK or any information regarding any Therapy or Licensed Product that is the subject of a Collaboration Program or license, whether prior to or after exercise of the applicable Option. Adaptimmune shall provide a copy of such proposed disclosure or presentation to GSK no less than thirty (30) calendar days prior to Adaptimmune’s intended submission for publication. GSK shall respond in writing promptly and in no event later than twenty (20) calendar days after receipt of the proposed material, with one or more of the following: (a) comments on the proposed material, which Adaptimmune shall

consider in good faith, (b) a specific statement of concern, based upon the need to seek patent protection of GSK’s Confidential Information, or (c) an identification of GSK’s Confidential Information that is contained in the material reviewed. In the event of concern over patent protection, Adaptimmune agrees not to submit such publication or to make such presentation that contains such information until GSK is given a reasonable period of time (not to exceed thirty (30) calendar days) to seek patent protection for any of its Confidential Information in such publication or presentation which it believes is patentable. With respect to all other non-patentable Confidential Information of GSK, such Confidential Information shall be deleted from the proposed publication. In the case of conference abstracts and other rapid scientific communications, the Parties will complete the review process in ten (10) Business Days or less.

10.6. This Agreement supersedes the Confidential Disclosure Agreement executed by the Parties dated 27 April 2010 (the “CDA”).

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 arbitrators; provided, that the arbitrator 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.

15.6. All proceedings and decisions of the arbitrators shall be deemed Confidential Information of each of the Parties, and shall be subject to Article 10.

15.7. From the date of submission of the dispute to the Executive Officers, until such time as the dispute has become finally settled by Third Party mediation or arbitration, the running of the time periods as to which a breaching Party must cure a breach of this Agreement becomes suspended as to any breach that is the subject matter of the dispute.

Schedule 4

PREVENTION OF CORRUPTION — THIRD PARTY GUIDELINES

The GSK Anti-Bribery and Corruption Policy (POL-GSK-007) requires compliance with the highest ethical standards and all anti-corruption laws applicable in the countries in which GSK (whether through a Third Party or otherwise) conducts business. POL-GSK-007 requires all GSK employees and any Third Party acting for or on behalf of GSK to ensure that all dealings with third parties, both in the private and government sectors, are carried out in compliance with all relevant laws and regulations and with the standards of integrity required for all GSK business. GSK values integrity and transparency and has zero tolerance for corrupt activities of any kind, whether committed by GSK employees, officers, or third-parties acting for or on behalf of the GSK.

Corrupt Payments — GSK employees and any Third Party acting for or on behalf of GSK, shall not, directly or indirectly, promise, authorise, ratify or offer to make or make any “payments” of “anything of value” (as defined in the glossary section) to any individual (or at the request of any individual) including a “government official” (as defined in the glossary section) for the improper purpose of influencing or inducing or as a reward for any act, omission or decision to secure an improper advantage or to improperly assist the company in obtaining or retaining business.

Government Officials — Although GSK’s policy prohibits payments by GSK or third parties acting for or on its behalf to any individual, private or public, as a “quid pro quo” for business, due to the existence of specific anticorruption laws in the countries where we operate, this policy is particularly applicable to “payments” of “anything of value” (as defined in the glossary section), or at the request of, “government officials” (as defined in the glossary section).

Facilitating Payments — For the avoidance of doubt, facilitating payments (otherwise known as “greasing payments” and defined as payments to an individual to secure or expedite the performance of a routine government action by government officials) are no exception to the general rule and therefore prohibited.

GLOSSARY

The terms defined herein should be construed broadly to give effect to the letter and spirit of the ABAC Policy. GSK is committed to the highest ethical standards of business dealings and any acts that create the appearance of promising, offering, giving or authorizing payments prohibited by this policy will not be tolerated.

Anything of Value: this term includes cash or cash equivalents, gifts, services, employment offers, loans, travel expenses, entertainment, political contributions, charitable donations, subsidies, per diem payments, sponsorships, honoraria or provision of any other asset, even if nominal in value.

Payments: this term refers to and includes any direct or indirect offers to pay, promises to pay, authorizations of or payments of anything of value.

Government Official shall mean:

· Any officer or employee of a government or any department, agency or instrument of a government;

Schedule 7

Technology Transfer

Full access by GSK and copies provided to GSK (including electronic) of all material, data, reports and documents will include, but not limited to the following, with the intent of all material supplied that are required to support development and obtain and maintain regulatory filing(s) and approval(s). The requirements only apply where a Therapy has progressed to a point in development where an item listed in this Schedule 7 is expected to exist as agreed by the JPT, JMC and JSC (e.g. it is not expected that clinical inventory will be available for an asset transferred at Clinical Development Candidate Selection).

Agreed Press Release

EMBARGOED FOR PUBLICATION OR TRANSMISSION TO 07:00 HRS GMT ON [XXXX] 2014

Adaptimmune enters strategic cancer immunotherapy collaboration with GlaxoSmithKline to develop and commercialise novel cell-based therapies

(Oxford, UK and Philadelphia, PA, [XXXXXX] 2014). Adaptimmune Limited, a leading biotechnology company developing TCR engineered T-cells to treat cancer, today announced that it has entered into a strategic collaboration and licensing agreement with GlaxoSmithKline (GSK) for the development and commercialisation of its lead clinical cancer programme.

Using its unique T-cell receptor (TCR) engineering technology, Adaptimmune has created TCRs which are deployed to target the cancer testis antigen, NY-ESO-1, and other targets. The company’s trials in the NY-ESO-1 programme in multiple myeloma, melanoma, sarcoma and ovarian cancer in the US are generating encouraging results, with European trials set to commence shortly, and it has a pipeline of follow-on programmes.

Under the terms of the agreement, Adaptimmune will co-develop its NY-ESO-1 clinical programme and associated manufacturing optimisation work together with GSK. GSK will have an option on the NY-ESO-1 programme through clinical proof of concept, anticipated during 2016, and, on exercise, will assume full responsibility for the programme. The companies will also co-develop other TCR target programmes and collaborate on further optimization of engineered TCR products.

According to the agreed development plan, the deal could yield payments in excess of $350 million to Adaptimmune over the next seven years, with significant additional development and commercialisation payments becoming due in subsequent years if GSK exercises all its options and milestones continue to be met. In addition, Adaptimmune would also receive tiered royalties ranging from single to double digits on net sales.

As part of its strategic commitment to the collaboration, Adaptimmune will immediately commence work on further TCR programmes with GSK.

James Noble, Chief Executive Officer of Adaptimmune, commented: “We are delighted to collaborate with GSK, a leading pharmaceutical company which has made a strategic

commitment to immuno-oncology. Its substantial development and manufacturing expertise in key areas will be invaluable as we work together to accelerate the development of our programmes and bring potentially breakthrough cancer therapies to patients.”

Axel Hoos, Vice President of Oncology R&D and Head of Immuno-Oncology of GSK, said: “We are very pleased to be working with Adaptimmune to co-develop new treatments in cancer immunotherapy, an exciting area of core strategic focus for GSK Oncology R&D. We believe that Adaptimmmune’s T-cell receptor engineering technology will be synergistic with the growing immuno-oncology portfolio of GSK and leverage our existing expertise in autologous cell gene therapy. Together this combination of capabilities offers an opportunity for significant progress in the use of the body’s immune system to fight cancer.”
