The Adaptimmune *** will be reviewed by the JDC and JSC, and the Parties will discuss in good faith and will mutually agree whether or not to proceed to the Co-Development Phase; provided that neither Party is required to proceed to the Co-Development Phase under discussion. The date of such mutual agreement of the Parties to proceed to the Co-Development Phase, as evidenced by minutes of the applicable JSC meeting, shall constitute “Co-Development Start”. Where the JSC does not and/or the Parties do not agree to proceed to the Co-Development Phase within *** of provision of such Adaptimmune *** and the POC Phase results by Adaptimmune, then this Agreement shall automatically terminate in accordance with Clause 17.5 (and in this event, Clause 17.7 shall apply).

ARTICLE 4 SELECTION OF TARGETS

4.1 Selected Targets.

4.1.1 Selected Target Identification. During the POC Phase, the Parties shall consult on and discuss at the JSC any Target being considered by a Party, either by selection from the Target List or the POC Target. The JSC shall agree upon which two Targets will be selected for co-development. The date of such selection by the JSC, as evidenced in minutes of the applicable JSC meeting, shall be the “Acceptance Date” for such two Targets. The JSC shall also designate which of the two Selected Targets is the Bellicum Target and which is the Adaptimmune Target. Agreement of the JSC on both Selected Targets must, unless otherwise mutually agreed between the Parties in writing, be made at the latest by ***

from Co-Development Start. Notwithstanding the foregoing, ***

4.1.2 Target Exclusivity. On the Acceptance Date, each of the two selected Targets shall thereafter be designated as a “Selected Target”. As of the Acceptance Date, a Selected Target will not be made available by Adaptimmune or Bellicum to any Third Party for development, and Adaptimmune will not develop any TCRs or Therapies to such Selected Targets for itself or for or on behalf of any Third Party.

5.1.1 Within *** after the Acceptance Date (or such longer time as mutually agreed by the Parties in writing) with respect to a given Selected Target, the JPT shall draft and agree upon a Co-Development Plan for the generation of Candidates directed to each Party’s Selected Target, which plan is intended to generate the data necessary to support an IND filing for such Party’s Joint Selected Candidate. No activities will be performed in connection with a proposed Co-Development Plan (and accordingly, no costs will be incurred under Clause 10.2) before the applicable JPT has agreed upon such Co-Development Plan. Each of the two Co-Development Plans shall:

(a) be prepared on a global basis;

(b) include the responsibilities of each of the Parties under the Co-Development Plan including as relates to any manufacture of Therapy for Clinical Trials;

(c) include a high level plan setting out an anticipated route (including Phase III Clinical Trials and other required trials) to obtain Regulatory Approval for such Therapy including estimated timelines and estimated budget; and

(d) include the basis for calculation of any budgeted costs, including relevant FTE and FTE Rate information to be applied to such budget (which FTE Rate(s) shall be used to calculate any Development Costs reimbursable in accordance with Clause 10).

5.1.2 Under each Co-Development Plan, each Party shall use Commercially Reasonable Efforts to perform any part of the Co-Development Plan assigned to it, including making resources available as and when required and supplying any product, equipment or materials as and when required and specified under the Co-Development Plan. The Parties may supplement the terms of this Agreement, as necessary, with terms relating to manufacture and supply, quality and/or any other terms deemed necessary or reasonably useful by a Party to govern the Parties’ co-development of such Party’s respective Candidate. The Parties will negotiate any such supplemental terms in good faith and on a timely basis to prevent any unreasonable delay to activities performed under the Co-Development Plan.

5.1.3 Under each Co-Development Plan, Adaptimmune shall use Commercially Reasonable Efforts to develop and validate starting TCRs (“Initial Candidates”) directed to each Party’s Selected Target within the timescales agreed for the relevant Co-Development Plan. ***

5.1.4 Subject to Clause 2.3.2(b), Clause 2.3.3 (which references the limitations set forth in Clause 2.2.4) and Clause 5.7, the JDC may amend in writing the Co-Development Plan for each Party’s Initial Candidate and Joint Selected Candidate from time to time and will regularly update the Parties’ Co-Development Plans as each phase of the plan progresses. It is envisioned that after ***

through each Co-Development Phase and in particular the criteria for designation of an Initial Candidate as a Joint Selected Candidate for progression into preclinical development and onwards into Clinical Trials. Initial criteria are set out in Exhibit 7 and these will be amended and reviewed by the JDC as appropriate. Only one Joint Selected Candidate shall proceed to pre-clinical development for any Co-Development Plan at any one time, and an alternative Candidate will only be selected for pre-clinical development where such initial Joint Selected Candidate fails to achieve the agreed criteria for completion of pre-clinical development (such alternative Candidate will be deemed the Joint Selected Candidate upon replacement of the original Joint Selected Candidate). ***

5.2 Subcontractors. Each Party may subcontract portions of its work under the Co-Development Plan to (i) any Affiliate or (ii) Third Parties; provided in the case of a Third Party, (a) there are no reasonably based objections from the other Party regarding the use of said subcontractor, and (b) such subcontract is in writing and is consistent with the terms and conditions of this Agreement including the confidentiality provisions of Article 13 and any rights granted to such subcontractor are restricted to only those rights necessary for performance by such subcontractor of the portions of work on behalf of the sub-contracting Party. The sub-contracting Party will remain fully responsible (at its cost) for all acts or omissions of any subcontractor it appoints (including any acts or omissions which result in a breach of the terms of this Agreement) and shall ensure that each subcontractor complies with the terms and conditions of this Agreement. Each Party shall notify the other Party in writing of any sub-contractor appointments other than Affiliates. In addition, either Party may audit any sub-contractor appointed by the other Party prior to such sub-contractor being appointed to perform any part of any Co-Development Plan, and on provision of written notice within *** of a Party becoming aware of such sub-contractor appointment. Such audit will occur as soon as reasonably practicable and in any event in accordance with any timelines set out in the applicable Co-Development Plan. The Party appointing such sub-contractor will provide reasonable assistance to enable the conduct of such audits (including interacting with such sub-contractors to substantiate the need and right to conduct such audits). To the extent any audit identifies any non-compliance with Applicable Laws (including non-compliance with GMP), the Party appointing such sub-contractor shall use reasonable efforts to procure correction of such non-compliance by sub-contractor or shall use an alternative sub-contractor where correction of such non-compliance is not possible or practicable. Each Party will put in place written Quality Agreements with any subcontractor performing GMP activities prior to them supplying materials or services supporting any relevant GMP activities under any Co-Development Plan. The other Party may request copies of such Quality Agreement to the extent necessary to satisfy its internal standard operating procedures or to satisfy obligations to any Regulatory Authority or under Applicable Laws.

5.3 Completion of any Co-Development Plan. The term for a particular Co-Development Plan shall commence on Acceptance, and shall continue, unless earlier terminated in accordance with Article 17, until the completion or waiver of all the tasks set out in the Co-Development Plan (on a Selected Target-by-Selected Target basis, the “Co-Development Term”). During the Co-Development Term and subject to reimbursement by the other Party under Clause 10.2, each Party shall be responsible for its own costs associated with the activities it conducts under the Co-Development Plan. The final report for each Co-Development Plan shall (i) identify all relevant data necessary for assessment by the JSC of whether the Candidate criteria have been met by any Joint Selected Candidate and (ii) include such data and research records that have been compiled and which may be required to support an IND filing for any Joint Selected Candidate.

If the Party with primary responsibility does not, within *** of receipt of a notice under Clause 12.5.2, take steps to defend the Third Party Infringement Claim, then to the extent that such Third Party Infringement Claim is brought against the other Party, the other Party shall have the right, but not the obligation, to take action to enforce or defend against such Third Party Infringement Claim; provided that if the Party with primary responsibility is diligently pursuing ongoing settlement discussions at the end of such *** period, then other Party shall not be permitted to exercise such right unless such settlement discussions cease without reaching settlement or such responsible Party ceases to pursue such settlement discussions diligently. At the controlling Party’s request and expense, the non-controlling Party shall cooperate with the controlling Party in connection with any such defense and counterclaim, provided that the non-controlling Party shall be reimbursed by the controlling Party as to any reasonable and documented costs or expenses, and shall have the right to be represented by its own counsel at its own expense. Any counterclaim or other similar action by a Party, to the extent such action involves any enforcement of rights under the Licensed Intellectual Property, Foreground IP or Joint IP, will be treated as an Enforcement subject to Clause 12.6. Nothing in this Clause 12.7 shall prevent any Party from complying with the terms of any court order relating to or arising out of any Third Party Infringement Claim.

15.1.9 it has the legal right and power to extend the rights and licenses granted to the other Party hereunder.

15.2 Disclaimers.

IN PARTICULAR BOTH PARTIES ACCEPT THAT, GIVEN THE NATURE OF THE CANDIDATES AND THERAPIES BEING GENERATED UNDER THIS AGREEMENT, THERE CAN BE NO GUARANTEE THAT ANY CANDIDATE CAN BE SUCCESSFULLY GENERATED OR THAT IF GENERATED, THE CANDIDATE OR ASSOCIATED THERAPY WILL BE CAPABLE OF OBTAINING REGULATORY APPROVAL.

ARTICLE 16 INDEMNIFICATION

16.1 Indemnification by Adaptimmune. Subject to Clause 16.3, Adaptimmune shall indemnify, defend and hold Bellicum, its Affiliates, their Sublicensees and their respective directors, officers, and employees and the successors and assigns of any of the foregoing harmless from and against any and all liabilities, damages, settlements, penalties, fines, costs or expenses (including reasonable attorneys’ fees and other reasonable expenses of litigation) (collectively, “Loss” or “Losses”) to the extent arising out of or in connection with any Third Party claims, suits, actions, demands or judgments (“Third Party Claims”) relating to (a) the negligence or willful misconduct of Adaptimmune or its Affiliates, Sublicensees or any of its or

Page 42

Execution Copy

their sub-contractors; and (b) any breach of Applicable Laws by Adaptimmune or its Affiliates, Sublicensees or any of its or their sub-contractors except, in each case, to the extent caused by the negligence or willful misconduct of Bellicum or its Affiliates or breach of this Agreement by Bellicum or its Affiliates.

16.2 Indemnification by Bellicum. Subject to Clause 16.3, Bellicum shall indemnify, defend and hold Adaptimmune, its Affiliates and their respective directors, officers, and employees and the successors and assigns of any of the foregoing harmless from and against any and all Losses to the extent arising out of or in connection with any Third Party Claims relating to (a) the negligence or willful misconduct of Bellicum, its Sublicensees or any sub-contractor of Bellicum (including its Affiliates); and (b) any breach of Applicable Laws by Bellicum, its Affiliates, Sublicensees or sub-contractors except, in each case, to the extent caused by the negligence or willful misconduct of Adaptimmune or its Affiliates or breach of this Agreement by Adaptimmune or its Affiliates.

16.3 Procedure. If a Party intends to claim indemnification under this Agreement (the “Indemnitee”), it shall promptly notify the other Party (the “Indemnitor”) in writing of such alleged Loss and the Third Party Claim. The Indemnitor shall have the right to control the defense thereof with counsel of its choice as long as such counsel is reasonably acceptable to Indemnitee. Any Indemnitee shall have the right to retain its own counsel at its own expense for any reason in connection with such Third Party Claim, provided, however, that if the Indemnitee shall have reasonably concluded, based upon a written opinion from outside legal counsel, that there is a conflict of interest between the Indemnitor and the Indemnitee in the defense of such action, the Indemnitor shall pay the fees and expenses of one law firm serving as counsel for the Indemnitee in relation to such Third Party Claim. The Indemnitee, its employees and agents, shall reasonably cooperate with the Indemnitor and its legal representatives in the investigation of any Third Party Claims covered by this Agreement. The obligations of this Article 16 shall not apply to any settlement of any Third Party Claims if such settlement is effected without the consent of both Parties, which shall not be unreasonably withheld or delayed. The failure to deliver written notice to the Indemnitor within a reasonable time after the commencement of any such action, to the extent prejudicial to its ability to defend such action, shall relieve the Indemnitor of any obligation to the Indemnitee under this Clause 16.3. It is understood that only Bellicum and Adaptimmune may claim indemnity under this Agreement (on its own behalf or on behalf of its Indemnitees), and other Indemnitees may not directly claim indemnity hereunder.

Such insurance policies of each Party shall be primary insurance.

16.5 Limitation of Damages. NEITHER PARTY HERETO WILL BE LIABLE FOR INDIRECT, INCIDENTAL, CONSEQUENTIAL, SPECIAL, EXEMPLARY, OR PUNITIVE DAMAGES, INCLUDING LOST PROFITS, ARISING FROM OR RELATING TO THIS AGREEMENT, REGARDLESS OF ANY NOTICE OF SUCH DAMAGES, EXCEPT IN RESPECT OF ANY BREACH OF (1) A PARTY’S OBLIGATIONS UNDER ARTICLE 12 OR 13, OR (2) INDEMNIFICATION OBLIGATIONS UNDER THIS ARTICLE 16 FOR THIRD PARTY CLAIMS. FOR THE AVOIDANCE OF DOUBT, NOTHING IN THIS CLAUSE SHALL LIMIT OR EXCLUDE ANY LIABILITY TO A THIRD PARTY FOR FRAUD BY ANY PARTY OR ANY LIABILITY ARISING AS A RESULT OF PERSONAL INJURY OR DEATH CAUSED BY NEGLIGENCE OF ANY PARTY. NOTHING IN THIS CLAUSE 16.5 SHALL LIMIT EITHER PARTY’S RIGHT TO PURSUE AND OBTAIN EQUITABLE RELIEF.

16.6 Therapy Recall. Bellicum shall be responsible for investigating any SUSAR or other complaint in relation to any Therapy comprising a Bellicum Candidate.

The responsible Party shall report its finding to the JDC or JCC, as relevant, once it has identified the reason for such complaint, SUSAR or has identified any requirement to recall any Therapy or any batch of Therapy. The responsible Party shall be responsible for carrying out any Therapy recall but shall keep the JDC or JCC, as relevant, informed of the status and process for such recall including any material correspondence with any Regulatory Authority. Where such recall is during the performance of any POC Plan or Co-development Plan, the costs associated with such recall will be shared between the Parties in the same way as other Co-Development Plan costs unless (a) such recall is due to any failure of responsible Party arising out of the manufacture or supply of Therapy or any part of the Therapy; or (b) any such costs are covered by applicable insurance policies. The costs associated with any recall during commercialisation of any Therapy and after Completion of the relevant Co-Development Plan shall be shared in accordance with the terms of the Co-Commercialisation Agreement or if none, Exhibit 3.

(a) Any Exclusive License granted to it, and such Party’s associated Co-Development Plan, where it believes that continuing with the applicable Candidate and Therapy comprising such Candidate causes or is likely to cause significant safety or efficacy concerns, and following written notification of such concerns to the other Party. Any termination under this Clause 17.5.3(a) shall be effective ninety (90) days after the other Party’s receipt of such notice;

(b) The Agreement in accordance with Clause 3.4, on provision of 30 days written notice to the other Party; and

(c) The Exclusive Licence under which a licence has been granted to the other Party to use any of such Party’s Licensed Intellectual Property, if the other Party or its Affiliates or Sublicensees commences proceedings (whether before a regulatory or administrative body or a court) anywhere in the world, or voluntarily assists any Third Party in commencing or participating in such proceedings (whether before a regulatory or administrative body or a court) alleging that any claim in any Patent within such Licensed Intellectual Property that is licensed to the other Party by such Party (including the Adaptimmune Background IP or Bellicum Background IP, as applicable) is invalid, unenforceable or otherwise not patentable, and such proceedings are not withdrawn within thirty (30) days after receipt of a written notice to withdraw. Notwithstanding the foregoing, a licence-granting Party shall have no right to terminate any Exclusive License pursuant to this Clause 17.5.3(c) if any proceedings are brought as a defense (including an affirmative defense) in relation to a claim of infringement brought against the other Party or its Affiliates or Sublicensees.

17.5.4 A Party may terminate the Exclusive License(s) granted to the Party undergoing a Change of Control (the “CoC Party”), such termination being subject to the following: (a) provision of written notice to such Party by the CoC Party within fourteen (14) days after the Change of Control is consummated; and (b) provision by such Party to the CoC Party of written notice of termination of such Exclusive License(s) granted by such Party within thirty (30) days of becoming notified of the Change of Control of the CoC Party; provided that such termination right will apply only with respect to any Candidate(s) that has not been designated as a Joint Selected Candidate of the CoC Party (i.e., a Candidate that has not been selected by the JDC for advancement to pre-clinical and clinical development) at the date of consummation of the Change of Control. For clarity, and with respect to Joint Selected Candidates of the CoC Party that exist at the date of consummation of the Change of Control, any Exclusive Licenses granted to the CoC Party for its existing Joint Selected Candidates shall remain in full force and effect after such Change of Control. To the extent the Party that is not the CoC Party determines earlier than expiry of the period of thirty (30) days from being notified of such Change of Control that it will not terminate the Exclusive License(s) granted by it, it will notify the CoC Party accordingly in writing, and such right to terminate the Exclusive License(s) granted to the CoC Party for such Change of Control shall cease on receipt of such written notice by the CoC Party.

17.5.5 Termination of the Agreement will also occur automatically in accordance with Clause 3.5.

17.6 Accrued Rights and Obligations. Expiration or termination of this Agreement in its entirety, or with respect to a particular Exclusive License, a given Therapy or Candidate, or a given country for any reason, shall not release either Party hereto from any liability which, as of the effective date of such expiration or termination, had already accrued to the other Party or which is attributable to a period prior to such termination, nor preclude either Party from

pursuing any rights and remedies it may have hereunder or at law or in equity which accrued or are based upon any event occurring prior to the effective date of such expiration or termination.

17.7 Effects of Termination. The effects of termination set forth in this Clause 17.7 shall apply either with respect to this Agreement in its entirety, if the Agreement is terminated in its entirety, or only with respect to a specific Therapy, Candidate or Exclusive License or country, if this Agreement is only terminated with respect to a specific Therapy, Candidate or Exclusive License or country, in all cases as applicable. For clarity, this Clause 17.7 shall not apply to any given Therapy and country with respect to which the Term naturally expires.

(b) Upon termination of a particular Exclusive License granted by Bellicum pursuant to Clause 17.3, Clause 17.5, such Exclusive License and the related Development License to any Selected Target, Therapy or Candidate covered by such Exclusive License shall terminate as of the effective date of such termination. Adaptimmune shall ensure that it transfers to Bellicum all items and rights necessary for Bellicum to advance on its own through development and commercialization the Candidate/ Therapy that was the subject of the terminated Exclusive License.

17.7.3 Return of Confidential Information. Following expiry or any early termination of this Agreement, the Party that has Confidential Information of the other Party shall to the extent reasonably possible destroy (at such Party’s written request) or put beyond use all such Confidential Information in its possession as of the effective date of expiration or termination (with the exception of one copy of such Confidential Information, which may be retained by the legal department of the Party that received such Confidential Information solely for purposes of ensuring compliance with confidentiality obligations), provided that each Party may retain and continue to use such Confidential Information of the other Party to the extent necessary to exercise any surviving rights, licenses or obligations under this Agreement or any obligation under Applicable Laws. This clause shall not require return or destruction of any Confidential Information which is held on back-up servers or archive systems, provided such back-ups have been made as part of the routine business of a Party and such back-ups are not accessible other than

To the extent any continuing requirement to supply exists after such termination, the Parties may mutually agree that the non-breaching Party can continue to supply to the breaching Party to fulfill any such continuing supply requirement.

17.7.5 Right to take over Manufacture, Sell and Supply. On termination of any Exclusive License where such termination is for a material breach by the other Party under Clause 17.3 or in the event of insolvency under Clause 17.4 or under Clause 17.5.1(b) or Clause 17.5.2(b) or under Clause 17.5.3(c), and upon the Parties’ negotiation and execution of a corresponding written agreement containing mutually agreed, commercially reasonable terms and conditions pursuant to Clause 17.7.6, the terminating Party shall be entitled to take over the manufacture, supply and development of the relevant Joint Selected Candidate and any Therapy utilising the Joint Selected Candidate that are the subject of the terminated Exclusive License.

Where any agreement terms have not been finalised within ninety (90) days of the effective date of termination, such unresolved terms may be forwarded to the respective officers of the Parties set out in Clause 18.1 for resolution. Where such respective officers remain unable to resolve any unresolved terms within a further sixty (60) days of the date of referral to such respective officers, then (i) in relation to any unresolved terms that relate to the compensation which breaching Party should receive under such agreement, then such unresolved terms shall be determined by arbitration in accordance with Clause 18.2.

documents and do such further acts as may be required for the purpose of giving full effect to this Agreement.

21.11 Interpretation. The captions and headings to this Agreement are for convenience only, and are to be of no force or effect in construing or interpreting any of the provisions of this Agreement. Unless context otherwise clearly requires, whenever used in this Agreement: (a) the words “include” or “including” shall be construed as incorporating “but not limited to” or “without limitation”; (b) the words “hereof,” “herein,” “hereby” and derivative or similar words refer to this Agreement, including the Exhibits; (c) the word “law” or “laws” means any applicable, legally binding statute, ordinance, resolution, regulation, code, guideline, rule, order, decree, judgment, injunction, mandate or other legally binding requirement of a governmental authority (including a court, tribunal, agency, legislative body or other instrumentality of any (i) government or country or territory, (ii) any state, province, county, city or other political subdivision thereof, or (iii) any supranational body); (d) all references to the word “will” are interchangeable with the word “shall” and shall be understood to be imperative or mandatory in nature; (f) the singular shall include the plural and vice versa; and (g) the word “or” has the inclusive meaning represented by the phrase “and/or”.

21.12 Other Activities. The Parties acknowledge that each of them may now or in the future engage in research, manufacturing, development or commercialisation activities that utilize technologies similar to or involve therapies or pharmaceutical products competitive with those contemplated by this Agreement. Except as may be expressly provided in this Agreement, nothing in this Agreement, including any obligation to use Commercially Reasonable Efforts to promote Therapies or any restriction on the use of Confidential Information, shall create any obligation not to research, manufacture, develop or commercialize any Therapy or any obligation to utilize a separate sales force for Therapies.

Each Party agrees to inform its key personnel assigned to perform activities hereunder of the limitations on use of Confidential Information contained in this Agreement, instruct such personnel to comply with such restrictions, and where appropriate, impose firewalls or other appropriate measures to minimize the potential for misuse of information. However, each Party has limited resources, and as a result it is anticipated that personnel assigned to activities hereunder may also participate in other activities that may utilize technologies similar to or involve therapies or pharmaceutical products competitive with those contemplated by this Agreement. In particular, it is anticipated that personnel in sales, marketing, clinical and regulatory functions, regardless of level, will participate in multiple programs and that management personnel will by nature of their leadership positions participate in multiple programs.

21.13 Counterparts. This Agreement may be executed in two or more counterparts, each of which will be deemed an original, but all of which together will constitute one and the same instrument. For purposes hereof, a facsimile copy, or email with attached pdf copy, of this Agreement, including the signature pages hereto, will be deemed to be an original.

Adaptimmune and Bellicum Pharmaceuticals Enter a Strategic Collaboration to Evaluate Next-Generation

T-Cell Therapies

PHILADELPHIA, PA, OXFORD, UK, and HOUSTON, TX – December XX, 2016 – Adaptimmune Therapeutics plc (Nasdaq: ADAP), a leader in T-cell therapy to treat cancer, and Bellicum Pharmaceuticals, Inc. (Nasdaq: BLCM), a leader in developing novel, controllable cellular immunotherapies for cancers and orphan inherited blood disorders, today announced that they have entered into a staged collaboration to evaluate, develop, and commercialize next-generation T-cell therapies.

Under the agreement, the companies will evaluate Bellicum’s GoTCR technology (inducible MyD88/CD40 co-stimulation, or iMC) with Adaptimmune’s affinity-optimized SPEAR™ T-cells for the potential to create enhanced TCR product candidates. Depending on results from the preclinical proof-of-concept phase, the companies expect to progress to a two-target co-development and co-commercialization phase.

“We are committed to advancing our clinical pipeline of proprietary cell therapies and to entering strategic collaborations that can further leverage the unique potential of our controllable T-cell technologies,” commented Tom Farrell, President and Chief Executive Officer of Bellicum. “We’re looking forward to working with the Adaptimmune team to create and advance potentially best-in-class TCR therapies.”

“As we advance our deep pipeline of second- and third-generation SPEAR T-cell therapies, we are excited by the potential of Bellicum’s iMC switch to complement the activity of our affinity enhanced T-cell therapies, as part of our continuing initiative to assess novel cell therapy enhancement technologies,” said James Noble, Adaptimmune’s Chief Executive Officer. “This is an innovative field that requires broad, industry-wide collaborations, such as our relationship with Bellicum and its strong leadership position in switch technology.”

About Bellicum’s iMC Technology

Bellicum’s Chemical Induction of Dimerization (CID) technology platform was designed to address the challenges of current cellular immunotherapies by enabling control over cellular activities and functions, such as growth, activation, proliferation, persistence and survival. Bellicum’s CID platform consists of molecular switches—modified forms of signaling proteins—which are triggered inside the patient by infusion of small molecule rimiducid, instead of by natural upstream signals. Current product candidates incorporate either the CaspaCIDeâ safety switch, or iMC activation switch. After rimiducid is administered, CaspaCIDe is designed to trigger programmed cell death, or apoptosis, and iMC is designed to drive proliferation, activation and/or persistence of T cells.

About Adaptimmune’s TCR Technology

Adaptimmune’s proprietary SPEAR™ (Specific Peptide Enhanced Affinity Receptor) T-cell receptor (TCR) technology enables the Company to genetically optimize TCRs in an effort to equip them to recognize and bind cancer antigens that are presented in small quantities on the surface of a cancer cell, whether of intracellular or extracellular origin, thus initiating cell death. The Company’s differentiated, proprietary

technology allows it to reliably generate parental TCRs to naturally presented targets, affinity optimize its TCRs to bind cancer proteins from solid and hematologic cancers that are generally unavailable to naturally occurring TCRs, and to significantly reduce the risk of side effects resulting from off-target binding of healthy tissues.

About Bellicum Pharmaceuticals

Bellicum is a leader in developing novel, controllable cellular immunotherapies for cancers and orphan inherited blood disorders. Bellicum is using its proprietary Chemical Induction of Dimerization (CID) technology platform to engineer and control components of the immune system. Bellicum is developing next-generation product candidates in some of the most important areas of cellular immunotherapy, including hematopoietic stem cell transplantation (HSCT), and CAR T and TCR cell therapies.

About Adaptimmune

Adaptimmune is a clinical stage biopharmaceutical company focused on novel cancer immunotherapy products based on its SPEAR (Specific Peptide Enhanced Affinity Receptor) T-cell platform. Established in 2008, the Company aims to utilize the body’s own machinery - the T-cell - to target and destroy cancer cells by using engineered, increased affinity TCRs as a means of strengthening natural patient T-cell responses. Adaptimmune’s lead program is a SPEAR T-cell therapy targeting the NY-ESO cancer antigen. Its NY-ESO SPEAR T-cell therapy has demonstrated signs of efficacy and tolerability in Phase 1/2 trials in solid tumors and in hematologic cancer types, including synovial sarcoma and multiple myeloma. Adaptimmune has a strategic collaboration and licensing agreement with GlaxoSmithKline for the development and commercialization of the NY-ESO TCR program. In addition, Adaptimmune has a number of proprietary programs. These include SPEAR T-cell therapies targeting the MAGE-A10 and AFP cancer antigens, which both have open INDs, and a further SPEAR T-cell therapy targeting the MAGE-A4 cancer antigen that is in pre-clinical phase with IND acceptance targeted for 2017. The Company has identified over 25 intracellular target peptides preferentially expressed in cancer cells and is currently progressing 12 through unpartnered research programs. Adaptimmune has over 250 employees and is located in Oxfordshire, U.K. and Philadelphia, USA. For more information: http://www.adaptimmune.com
