(b)     Within a […***…] day period commencing on the later to occur of (i) Bellicum’s exercise of its option to expand the Licensed Field to include Additional Indications pursuant to Section 2.1.2(a) and (ii) Bellicum’s or its Affiliate’s or Sublicensee’s commencing a […***…], or, […***…] (the “Non-Cancer Expansion Period”), Bellicum may, at Bellicum’s election, request that ARIAD agree to expand the Licensed Field to specific non-cancer indications (other than Cell Transplantation Indications) by delivering written notice to ARIAD within such Non- Cancer Expansion Period which describes the specific products and associated product development plans, capabilities and resources for the specific non-cancer diseases and/or conditions it desires to include within the Licensed Field. Upon receipt of such written notice, ARIAD shall in good faith consider Bellicum’s request. If ARIAD is willing to so expand the Licensed Field, the Parties will negotiate with respect to a possible amendment to this Agreement setting forth all relevant terms (including milestones and royalties) pertaining to the expansion for a period of […***…] days from the date of ARIAD’s receipt of the written request (the “Non-Cancer Negotiation Period”). If the Parties do not agree upon terms and conditions mutually acceptable to both Parties on or before the expiration of such Non-Cancer Negotiation Period despite their respective good faith efforts, then Bellicum shall have no further rights with respect to such expansion and ARIAD shall have no further obligation to negotiate pursuant to this Section 2.1.2.

2.1.3     Certain Exclusivity Rights. Notwithstanding anything to the contrary in this Agreement:

(a)     ARIAD will not license (or sublicense) to any Third Party or develop or commercialize itself or together with any Third Party, for use in the treatment or prevention of (i) the Primary Indication or (ii) any Additional Indication which Bellicum elects to include in the Licensed Field pursuant to the provisions of Section 2.1.2(a) or any non-cancer indication (other than Cell Transplantation Indications) that is included in the Licensed Field pursuant to the provisions of Section 2.1.2(b), any Dimerizer or other product involving the use of a Dimerizer covered by Bellicum Patent Rights or Bellicum Technology or any Patent Rights covering the […***…]-ARIAD MTA Technologies licensed to ARIAD by […***…] as of the Original Effective Date or during the Primary License Term.

If the […***…] Agreement is terminated, then from and after the effective date of such termination, the license granted by ARIAD to Bellicum under the […***…] IP shall be deemed a direct license from […***…] to Bellicum and all obligations of Bellicum under this Agreement with regard to such license under the […***…] IP, and all obligations of ARIAD under the […***…] Agreement with regard to Licensed Products (as defined herein) developed, made, used or sold by Bellicum or any Affiliate or Sublicensee of Bellicum that would be “Licensed Products” under the […***…] Agreement including the payment of royalties to […***…], shall be deemed obligations of Bellicum to […***…]. As long as Bellicum has not materially breached any material obligation or condition that would entitle ARIAD to terminate this Agreement, ARIAD will not voluntarily terminate or willfully breach the […***…] Agreement. In addition to specific provisions in this Agreement relating to the […***…] Agreement, the provisions of Articles 8, 9 and 10 of the […***…] Agreement, with Bellicum substituted for AGTI in such provisions, are expressly included in this Agreement for the benefit or […***…], […***…] and […***…]. To the extent the provisions of Articles 8, 9 and 10 of the […***…] Agreement cover the same subject matter as other provisions in this Agreement relating

to the […***…] Agreement, the provisions imposing the greatest obligation on Bellicum shall apply.

(a)     Bellicum hereby grants to ARIAD a non-exclusive, royalty-free (subject only to Section 2.2.1(b)) license, including the right to grant sublicenses, under the Bellicum Patent Rights and Bellicum Technology, and Bellicum’s interest in any Improvements, to develop, make, have made, use, have used, sell, offer for sale, have sold, import, have imported, export and have exported ARIAD Products (including products comprising or utilizing AP1903) for any and all uses outside of the Licensed Field, subject to the terms and conditions of this Agreement. In no event will ARIAD practice any Bellicum Patent Rights or Bellicum Technology, or Bellicum’s interest in any Improvements (excluding any Improvements licensed to Bellicum and ARIAD by     […***…] that cover any of the […***…]-ARIAD MTA Technologies), for any use within the Licensed Field or to sell, offer for sale, have sold, import, have imported, export and have exported any ARIAD Product (including any product comprising or utilizing AP1903) for any use outside of the Licensed Field, if such ARIAD Product is the same (for regulatory purposes) as any Licensed Product listed on Schedule B pursuant to Section 3.2.1 prior to ARIAD’s commencement of the development thereof and that is being developed or commercialized to ARIAD’s knowledge by Bellicum or any of its Affiliates or Sublicensees for any use within the Licensed Field (an “Existing Bellicum Product”). In the event that Bellicum has not filed an IND for a particular Licensed Product within     […***…] after such Licensed Product is listed on Schedule B, then the foregoing prohibition shall not apply to such Licensed Product. Notwithstanding the foregoing, ARIAD shall be free to develop, make, have made, use, have used, sell, offer for sale, have sold, import, have imported, export and have exported, any Dimerizer for any purpose without restriction, except that ARIAD shall not sell, offer for sale, have sold, import, have imported, export or have exported any Dimerizer covered by Bellicum Patent Rights that is specifically labeled by ARIAD for use with an Existing Bellicum Product.

(b)     If any Bellicum Patent Rights or Bellicum Technology licensed to Bellicum by any Third Party would require payment to such Third Party upon ARIAD’s practice thereof pursuant to the license granted under this Section 2.2.1, then Bellicum shall so notify ARIAD in writing promptly after obtaining the license. ARIAD may, by written notice to Bellicum provided at any time prior to the First Commercial Sale of any ARIAD Product utilizing the subject matter of the Bellicum Patent Rights or Bellicum Technology licensed to Bellicum by the Third Party, (i) elect to accept the license to such Bellicum Patent Rights or Bellicum Technology, in which case, ARIAD shall be responsible for making any payment to such Third Party resulting from ARIAD’s practice of such Bellicum Patent Rights or Bellicum Technology pursuant to the license granted under this Section 2.2.1 and shall provide Bellicum written notice confirming that it has made such payments (and, if it fails to make any such payment in accordance with the terms of the agreement with such Third Party, the license to such Bellicum Patent Rights or Bellicum Technology under this Section 2.2.1 shall terminate), or (ii) elect to decline the license to such Bellicum Patent Rights or Bellicum Technology (and shall be deemed to decline the license to such Bellicum Patent Rights or Bellicum Technology if it does not provide Bellicum written notice of its election as set forth above), in which case such Bellicum Patent Rights or Bellicum Technology shall be excluded from the license granted to ARIAD under this Section 2.2.1.

Commencing as of the date of First Commercial Sale of the first Licensed Product hereunder, Bellicum and its Affiliates and Sublicensees shall keep for at least […***…] from the end of the calendar year to which they pertain complete and accurate records of sales by Bellicum or its Affiliates and Sublicensees, as the case may be, of each Licensed Product, in sufficient detail to allow the accuracy of the payments hereunder to be confirmed.

4.3.2    Review. Subject to the other terms of this Section 4.3.2, at the request of ARIAD, which shall not be made more frequently than […***…] during the Term, upon at least […***…] prior written notice from ARIAD, and at the expense of ARIAD (except as otherwise provided herein), Bellicum shall permit an independent certified public accountant reasonably selected by ARIAD and reasonably acceptable to Bellicum to inspect (during regular business hours) the relevant records required to be maintained by Bellicum under this Section 4.3 (provided no records may be reviewed more than once under this Section 4.3.2). Results of any such review shall be binding on both Parties absent manifest error. ARIAD agrees to treat the results of any such accountant’s review of records under this Section 4.3 as Confidential Information of Bellicum subject to the terms of Section 5. If any review reveals a deficiency in the calculation and/or payment of royalties by Bellicum, then (a) Bellicum shall promptly pay ARIAD the amount remaining to be paid, and (b) if such underpayment is by     […***…] percent ([…***…]%) or more, Bellicum shall pay the reasonable out-of- pocket costs and expenses incurred by ARIAD in connection with the review. If any review reveals an overpayment of royalties by Bellicum, ARIAD shall promptly remit such overpaid amounts to Bellicum.

5.1     Confidential Obligations. The Mutual Non-Disclosure Agreement between the Parties dated October 16, 2004 (the “Confidentiality Agreement”) shall apply to information provided under this Agreement. Each Party shall take such action, and shall cause its Affiliates or Sublicensees to take such action, to preserve the confidentiality of each other’s Confidential Information as it would customarily take to preserve the confidentiality of its own Confidential Information, using, in all such circumstances, not less than reasonable care to prevent the Confidential Information of the other Party from being copied, used or disclosed to any Third Party without the other Party’s prior written consent except for those Third Parties to whom disclosure of the Confidential Information is permitted pursuant to the terms of the Confidentiality Agreement. To the extent of any conflict between the provisions of this Article 5 and the Confidentiality Agreement, the provisions of this Article 5 shall control and pertain to all information provided under this Agreement and the Confidentiality Agreement, retroactive to October 16, 2004.

5.2     Limited Disclosure and Use. ARIAD and Bellicum each agree that any disclosure of the other Party’s Confidential Information to any officer, employee, consultant or agent of the other Party or any of its Affiliates or Sublicensees shall be made only if and to the extent necessary to carry out its rights and responsibilities under this Agreement, shall be limited to the maximum extent possible consistent with such rights and responsibilities and shall only be made to the extent any such persons are bound by written confidentiality obligations to maintain the confidentiality thereof and not to use such Confidential Information except as expressly permitted by this Agreement. ARIAD and Bellicum each further agree not to disclose or transfer the other Party’s Confidential Information to any Third Parties under any circumstance without the prior written approval from the other Party (such approval not to be unreasonably withheld), except as otherwise required by law, and except as otherwise expressly permitted by this Agreement. Each Party may disclose the Confidential Information of the other Party to any investors, prospective investors, lenders and other potential financing sources and Third Parties conducting due diligence in connection with any financing or acquisition transaction who are obligated to keep such information confidential. Each Party, upon the request of the other Party, will return all the Confidential Information disclosed or transferred to it by the other Party pursuant to this Agreement, including all copies and extracts of documents and all manifestations in whatever form, within […***…] of such request or, if earlier, the termination or expiration of this Agreement; provided however, that a Party may retain (a) any Confidential Information of the other Party relating to any license which expressly survives such termination and (b) one (1) copy of all other Confidential Information in inactive archives solely for the purpose of establishing the contents thereof.

5.3     Publicity. Neither Party may publicly disclose the existence or terms or any other matter of fact regarding this Agreement without the prior written consent of the other Party, which consent shall not be unreasonably withheld or delayed; provided, however, that (a) either party may issue a press release upon execution hereof, (b) either Party may make such a disclosure (i) to the extent required by law or by the requirements of any nationally recognized securities exchange, quotation system or over-the-counter market on which such Party has its securities

listed or traded, and (ii) to any investors, prospective investors, lenders and other potential financing sources who are obligated to keep such information confidential, provided that in the event that such disclosure is required under clause (b)(i) of this Section 5.3, the disclosing Party shall provide the other Party with notice beforehand and, to the extent reasonably practical, coordinate with the other Party with respect to the wording and timing of any such disclosure, and (c) ARIAD may disclose the filing by Bellicum or a Sublicensee with the FDA or any other Regulatory Authority of any IND, NDA, BLA or equivalent application or the commencement by Bellicum or a Sublicensee of any clinical trial, provided that ARIAD may only disclose such filing or commencement by a Sublicensee (x) if (i) Bellicum or the Sublicensee makes prior public disclosure of such filing or commencement and (ii) ARIAD provides Bellicum with notice beforehand and, to the extent reasonably practical, coordinates with Bellicum with respect to the wording and timing of any such disclosure or (y) if the Sublicensee consents. If Bellicum or the Sublicensee does not intend to make prior public disclosure of such filing or commencement, Bellicum will so notify ARAIAD with the notice thereof pursuant to Section 3.2.1 and will use good faith efforts to obtain the consent of the Sublicensee for ARIAD to make such disclosure. Once any press release or any other written statement is approved for disclosure by both Parties, either Party may make subsequent public disclosure of the contents of such statement without the further approval of the other Party.

5.4     Use of Name. Neither Party shall employ or use the name of the other Party or the name of […***…], […***…], […***…] or […***…] in any promotional materials or advertising without the prior express written permission of the other party.

5.5     […***…]. Notwithstanding anything to the contrary in this Agreement, ARIAD may disclose the terms of this Agreement and Bellicum’s Confidential Information (including the terms of any Bellicum sublicense) to […***…] as reasonable and necessary required to fulfill its obligations under the […***…] Agreement.

6.1     Patent Filing, Prosecution, Maintenance and Enforcement. ARIAD shall have the sole right, but not the obligation, to prepare, file, prosecute, obtain and maintain, and a first right to enforce, any Licensed Patent Rights (excluding all Patent Rights licensed to Bellicum by […***…] that cover any of the         […***…]-ARIAD MTA Technologies). In the event that ARIAD elects not to enforce any of the Licensed Patent Rights, if the alleged infringement is in the Licensed Field with a product that comprises a cell transfected with both (but not limited to) a gene for an Antigen and one or more genes for Inducible Costimulatory Molecule(s) where the gene or genes for the Inducible Costimulatory Molecule(s) are activated using an ARIAD Dimerizer or a Non-ARIAD Dimerizer, Bellicum may do so at its sole expense; provided that, if the Licensed Patent Right alleged to be infringed is a patent other than a Licensed Patent Right covering any of the […***…]-ARIAD MTA Technologies, Bellicum may do so only with the advance written consent of ARIAD, which may be granted or withheld in ARIAD’s sole discretion. Bellicum may recover, collect and keep any damages collected as a result of such enforcement by Bellicum. Bellicum shall have the sole right, but not the obligation, to prepare, file, prosecute, obtain, maintain and enforce any Bellicum Patent Rights, and as between Bellicum and ARIAD, Bellicum shall have the sole right to prepare, file, prosecute, obtain and maintain any Patent Rights licensed to Bellicum by […***…] that cover any of the […***…]-ARIAD MTA Technologies in accordance with the terms and conditions agreed upon between Bellicum and […***…]. Subject to any rights granted, at any time, by Bellicum to its Affiliates and/or Sublicensees, in the event that Bellicum elects not to enforce any of the Bellicum Patent Rights, ARIAD may do so only at its own expense and only with the advance written consent of Bellicum, which may be granted or withheld in Bellicum’s sole discretion. ARIAD may recover, collect and keep any damages collected as a result of such enforcement by ARIAD.

To the extent Bellicum assumes enforcement of Licensed Patent Rights or ARIAD assumes enforcement of Bellicum Patent Rights under this Section 6, and later elects not to enforce such rights, such Party will notify the other Party in writing promptly upon such election not to so enforce, and in any event, at least […***…] prior to the deadline to submit any filing related thereto.

7.3.1     Nothing in this Agreement is or shall be construed as:

(a)     a warranty or representation by either Party as to the validity or scope of any patent application or patent licensed hereunder;

(b)     a warranty or representation that anything made, used, sold or otherwise disposed of under any license granted pursuant to this Agreement is or will be free from infringement of patents, copyrights, and other rights of third parties;

7.3.2     EXCEPT AS EXPRESSLY SET FORTH IN THIS AGREEMENT, NEITHER PARTY MAKES ANY REPRESENTATION OR EXTENDS ANY WARRANTIES OF ANY KIND, EITHER EXPRESS OR IMPLIED. THERE ARE NO EXPRESS OR IMPLIED WARRANTIES OF MERCHANTABILITY OR FITNESS FOR A PARTICULAR PURPOSE, OR OF NON-INFRINGEMENT OF ANY PATENT, COPYRIGHT, TRADEMARK, OR OTHER RIGHTS OF THIRD PARTIES, OR ANY OTHER IMPLIED WARRANTIES.

8.1.2     ARIAD Indemnity. Subject to Section 8.1.1 above, ARIAD shall indemnify, defend and hold harmless Bellicum, its Affiliates and Sublicensees and their respective directors, officers, employees, and agents, and their respective successors, heirs and assigns (the “Bellicum Indemnitees”), from and against any Losses incurred by or imposed upon such Bellicum Indemnitees, or any of them, in connection with any Third Party claims, suits, actions, demands or judgments, including, without limitation, personal injury and product liability matters, to the extent arising out of (a) the development, testing, production, manufacture, supply,

Upon any termination of this Agreement by ARIAD or Bellicum under Section 9.2.1 or by Bellicum pursuant to Section 9.2.2, as of the effective date of such termination all relevant licenses and sublicenses granted by ARIAD to Bellicum shall terminate automatically. Upon any termination of this Agreement by ARIAD or Bellicum under Section 9.2.1 or by Bellicum pursuant to Section 9.2.2, subject to applicable statutes, laws, regulations, ordinances and guidelines governing the transfer of the Orphan Drug Designation and any similar designation in any jurisdiction of orphan drug status for AP1903, Bellicum will transfer, assign and convey all its ownership of and any beneficial interest in the Orphan Drug Designation and any similar designation in any jurisdiction of orphan drug status for AP1903 to ARIAD, effective as of the date of termination, and within ten (10) days of such termination, ARIAD and Bellicum shall each submit the required information to the FDA and any other relevant Regulatory Authority to effect the change of the named sponsor of the Orphan Drug Designation and any similar designation in any jurisdiction of orphan drug status for AP1903 from Bellicum to ARIAD in accordance with the applicable statutes, laws, regulations, ordinances and guidelines, and Bellicum shall transfer a complete copy of the Orphan Drug Designation and any similar designation in any jurisdiction of orphan drug status for AP1903, including any amendments or supplements thereto, and correspondence relating thereto, to ARIAD. No termination of this Agreement shall affect ARIAD’s rights pursuant to the Investor Rights Agreement, dated as of July 25, 2006, as amended, except as stated therein. Notwithstanding the foregoing, and subject at all times to the provisions of the […***…] Agreement with respect to the […***…] IP to the extent a license under such […***…] IP is granted to Bellicum under this Agreement, (a) no such termination of this Agreement shall be construed as a termination of any valid sublicense of any Sublicensee hereunder, and thereafter each such Sublicensee shall be considered a direct licensee of ARIAD, provided that (i) such Sublicensee is then in full compliance with all terms and conditions of its sublicense, (ii) all accrued payments obligations of such Sublicensee to ARIAD have been paid, and (iii) such Sublicensee agrees in writing to assume all applicable obligations of Bellicum under this Agreement arising thereafter to the extent

Without limiting the generality of the foregoing, Bellicum shall have no obligation to make any milestone or royalty payment to ARIAD that has not accrued prior to the effective date of any termination of this Agreement, but shall remain liable for all such payment obligations accruing prior to the effective date of such termination.

10.1      Negotiation. The Parties recognize that a bona fide dispute as to certain matters may from time to time arise during the Term that relates to either Party’s rights and/or obligations hereunder. In the event of the occurrence of such a dispute, either Party may, by written notice to the other Party, have such dispute referred to their respective senior officials designated below or their successors, for attempted resolution by good faith negotiations within […***…] after such notice is received. Said designated senior officials are as follows:

For Bellicum: Chief Executive Officer

For ARIAD: Chief Executive Officer

In the event the designated senior officials are not able to resolve such dispute within the […***…] period, either Party may invoke the provisions of Section 10.2.

10.2     Arbitration. Subject to Section 10.1, any dispute, controversy or claim initiated by either Party arising out of, resulting from or relating to this Agreement, or the performance by either Party of its obligations under this Agreement (other than bona fide Third Party actions or proceedings filed or instituted in an action or proceeding by a Third Party against a Party), whether before or after termination of this Agreement, shall be finally resolved by binding arbitration. Whenever a Party shall decide to institute arbitration proceedings, it shall give written notice to that effect to the other Party. Any such arbitration shall be conducted under the Commercial Arbitration Rules of the American Arbitration Association by a panel of three arbitrators appointed in accordance with such rules. Any such arbitration shall be held in Boston, Massachusetts. The method and manner of discovery in any such arbitration proceeding shall be governed by the laws of the State of New York. The arbitrators shall have the authority to grant injunctions and/or specific performance and to allocate between the parties the costs of arbitration in such equitable manner as they determine. Judgment upon the award so rendered may be entered in any court having jurisdiction or application may be made to such court for judicial acceptance of any award and an order of enforcement, as the case may be. In no event shall a demand for arbitration be made after the date when institution of a legal or equitable proceeding based upon such claim, dispute or other matter in question would be barred by the applicable statute of limitations. Notwithstanding the foregoing, either Party shall have the right, without waiving any right or remedy available to such Party under this Agreement or otherwise, to seek and obtain from any court of competent jurisdiction any interim or provisional relief that is necessary or desirable to protect the rights or property of such Party, pending the selection of the arbitrators hereunder or pending the arbitrators’ determination of any dispute, controversy or claim hereunder.

11.1.1      To the extent and for so long as any […***…] IP is licensed to Bellicum under Section 2.1.1 and as required by the […***…] Agreement, Bellicum shall comply with the terms of this Section 11.1.1. Bellicum shall comply, through insurance written by reputable and financially secure insurance carriers, with all statutory workers’ compensation and employers’ liability requirements covering any and all employees with respect to its activities performed under this Agreement. In addition to the foregoing, Bellicum shall maintain Comprehensive General Liability Insurance, including Products Liability Insurance, covering Bellicum’s indemnification obligations hereunder, with reputable and financially secure insurance carrier(s) to cover the activities of Bellicum, its Affiliates and Sublicensees.

Commencing with human clinical trials of a Licensed Products, Bellicum shall maintain such insurance with minimum limits of liability of […***…] dollars ($[…***…]) per occurrence and […***…] dollars ($[…***…]) in aggregate and shall include ARIAD and […***…], […***…], […***…], […***…] and their respective trustees, directors, officers, employees, students, and agents as additional insureds. Such insurance shall be written to cover claims incurred, discovered, manifested, or made during and after the Term. At ARIAD’s request, Bellicum shall furnish a Certificate of Insurance evidencing primary coverage and requiring […***…] prior written notice of cancellation or material change to ARIAD. Bellicum shall advise ARIAD, in writing, that it maintains excess liability coverage (following form) over primary insurance for at least the minimum limits set forth above. All such insurance of Bellicum shall be primary coverage; insurance of the above additional insureds shall be excess and noncontributory. ARIAD acknowledges

that the insurance specified in this Section 11.1.1 may be or become unavailable or unavailable on commercially practicable terms. In such event, ARIAD agrees to discuss with Bellicum commercially reasonable alternatives. Each Party shall carry appropriate insurance covering such Party’s indemnification obligations under this Agreement, through insurance written by reputable and financially secure insurance carriers.

The Parties hereto acknowledge and agree that: (i) each Party and its counsel reviewed and negotiated the terms and provisions of this Agreement and have contributed to its revision; (ii) the rule of construction to the effect that any ambiguities are resolved against the drafting Party shall not be employed in the interpretation of this Agreement; and (iii) the terms and provisions of this Agreement shall be construed fairly as to all Parties hereto and not in favor of or against any Party, regardless of which Party was generally responsible for the preparation of this Agreement.

11.12     Severability. If any provision(s) of this Agreement are or become invalid, are ruled illegal by any court of competent jurisdiction or are deemed unenforceable under then current applicable law from time to time in effect during the Term hereof, it is the intention of the Parties that the remainder of this Agreement shall not be affected thereby provided that a Party’s rights under this Agreement are not materially affected.

11.16     Further Assurances. Each Party agrees to execute, acknowledge and deliver such further instructions, and to do all such other acts, as may be necessary or appropriate in order to carry out the purposes and intent of this Agreement.
