If such Licensor filings are not completed before prosecution control transfers to NewCo at the end of the Transition Period, NewCo and the Licensor shall cooperate in effecting such filings.

(b) For any Licensed Patent having any material applicability outside the Field, NewCo shall bear only a portion of its costs and expenses associated with

filing, prosecuting and maintaining the Licensed Patent, and the Licensor shall bear, and reimburse NewCo for, the remainder of such NewCo expenses. The equitable allocation of such costs and expenses shall be mutually agreed by the Licensor and NewCo based upon the scope of the claims in the Licensed Patent in the Field and outside the Field and the relative value of such claims scope. Except as otherwise provided in Section 7.4(a) herein, for any Licensed Patent having material applicability outside the Field, NewCo and the applicable Licensor shall mutually agree upon the strategy for filing, prosecuting and maintaining such Licensed Patents.

(c) For any Adversarial Action involving any Licensed Patent having any material applicability outside the Field, NewCo shall bear only a portion of its costs and expenses associated with such Adversarial Action, and the Licensor shall bear, and reimburse NewCo for, the remainder of such NewCo expenses. For any Adversarial Action involving any Licensed Patent having material applicability outside the Field, NewCo and the applicable Licensor shall mutually agree upon the strategy for defending and conducting such Adversarial Action and upon an equitable allocation of such costs, expenses and any recovery arising from such Adversarial Action. No settlement of or material concession with respect to such Adversarial Action shall be made or entered into without Licensor’s or NewCo’s consent.

(d) In any event, NewCo shall bear no costs under this Section 7.4 or Section 7.11 to the extent any third party is obligated to pay, reimburse or credit a Licensor or Third-Party Licensor (excluding a Licensor’s obligation to pay, reimburse or credit a Third-Party Licensor) for any such costs; in such event, and provided such costs have been incurred by or are owed by NewCo, such Licensor shall pay over to NewCo any such amounts to the extent that such amounts are not received by NewCo from such third party pursuant to Section 6 hereof. Further, NewCo shall receive the benefit afforded to any Licensor pursuant to a Third-Party License Agreement with respect to reimbursement of costs and expenses incurred by NewCo under this Section 7.4 and Section 7.11, and Licensors hereby agree to take all actions reasonably requested by NewCo to obtain such benefit, except in each case as may be otherwise agreed by NewCo in writing.

7.5 Licensor Cooperation.

(a) Each Licensor shall make reasonable commercial efforts to cooperate fully with NewCo to effectuate an orderly transition of the prosecution and maintenance relating to the Licensed Patents and to cooperate fully with NewCo in the preparation, filing, prosecution, maintenance and, as applicable, enforcement of all Licensed Patents. Cooperation includes, without limitation, (i) promptly executing all papers and instruments or requiring employees of such Licensor to execute papers and instruments as reasonably appropriate to enable NewCo to file, prosecute, maintain and enforce Licensed Patents in any jurisdiction; (ii) making available to NewCo (or to NewCo’s authorized attorneys, agents or representatives), such Licensor’s employees, agents or consultants to the extent necessary or appropriate to enable NewCo to file, prosecute and maintain patent applications and resulting patents with respect to Licensed Patents owned or licensed by a Licensor and for reasonable periods of time sufficient for

NewCo to obtain the assistance it needs from such personnel; and (iii) promptly informing NewCo of matters that may affect the preparation, filing, prosecution, future validity, or maintenance of Licensed Patents (such as becoming aware of material prior art or references thereto or of an additional inventor who is not listed as an inventor in a patent application).

(b) If NewCo requests travel by a Licensor (or its employees, agents or consultants) in connection with the preceding or, after the one-year anniversary of the Effective Date, directly requests in writing substantial legal advice from a Licensor’s outside legal counsel for which the Licensor is charged or from a Licensor’s in-house counsel (excluding any charges relating to file transfer, execution of papers and instruments and similar costs), NewCo will reimburse the Licensor for its out-of-pocket direct costs incurred for such travel or legal fees (or in the case of in-house counsel, the charge allocated to Licensor’s applicable business division for such in-house counsel’s time so incurred, in accordance with such Licensor’s standard past practices), provided Licensor first obtains NewCo approval of the estimated cost thereof. In order to allow NewCo to efficiently and economically prepare, file, prosecute, maintain and, as applicable, enforce the Licensed Patents, the Licensors shall not challenge the validity, enforceability or scope of the Licensed Patents through any means, including, without limitation, declaratory judgment actions, litigation proceedings, opposition proceedings, interference proceedings, and re-examination proceedings. Except as otherwise expressly provided for in this Agreement, a Licensor’s performance of its obligations and exercise of its rights under this Agreement shall be at the sole expense of such Licensor.

7.6 NewCo Cooperation. After the Transition Period, NewCo shall keep each Licensor informed of the status of prosecution of its Licensed Patents and provide such Licensor with copies of and the opportunity to comment on associated filings with patent authorities. NewCo will not unreasonably refuse to accept any reasonable suggestions of a Licensor’s patent counsel regarding any filings made by NewCo with a patent authority with respect to such Licensor’s Licensed Patent, provided that Licensor’s patent counsel provides such comments to NewCo in a timely manner (i.e. not less than thirty (30) days prior to the patent office deadline (excluding extensions) for such filing), and further provided that accepting such suggestion would not materially adversely affect the patentability, enforceability, or validity of claims or the scope of the claims of such patent or patent application having application within the Field. NewCo shall, if and to the extent required by any Third-Party License Agreement, keep the Third-Party Licensor informed of the status of prosecution of the applicable Third-Party Patents and provide such Third-Party Licensor with copies of and the opportunity to comment on associated filings with patent authorities.

7.7 Status Updates. Each Licensor agrees to keep NewCo informed in a timely manner of the status of its and any Third-Party Licensor’s (and UMass’, as applicable) activities relating to any of the Licensed Patents or Technology licensed to NewCo hereunder (e.g., developments of any on-going litigation, interference proceedings, or other activities that could affect the value, validity, or prosecution strategy of the Licensed Patents) to the extent such Licensor becomes aware of such activities.

7.8 Assignment of Prosecution Rights. Subject to Section 7.3 and 7.4 hereof, each Licensor shall, and if necessary shall use reasonable commercial efforts to cause any Third-Party Licensor (and UMass, as applicable) to, execute a power of attorney for the prosecution and maintenance of the Licensed Patents, assign to NewCo (in written form reasonably acceptable to NewCo) all its rights to prosecute and maintain the Licensed Patents in all jurisdiction(s), and otherwise perform all acts and make all filings necessary to permit NewCo and its designees to, effective as of the end of the Transition Period, prosecute, maintain and enforce each such patent or application in all jurisdiction(s) and transact all matters connected therewith, including by way of example but not limitation, controlling prosecution and resolving all interference, re-examination, re-issue, and opposition proceedings relating thereto. Such acts shall include changing the address of the patent attorney of record with the appropriate patent authorities and, as may be necessary on an interim or extended basis, appointing NewCo as a Licensor’s delegatee or agent for the purpose of continuing to exercise such Licensor’s prosecution, maintenance and enforcement rights under any of the Third-Party License Agreements and appointing NewCo’s patent counsel as associate attorneys of record. The foregoing assignment of rights shall include all rights to apply for, file, register, prosecute, maintain, extend or renew the Licensed Patents in all jurisdictions and to settle or otherwise terminate any interference proceedings, re-examinations, oppositions, or other challenges to the validity, enforceability or scope of any Licensed Patent, and the right to bring actions for past, present or future infringement of or otherwise enforce any of the Licensed Patents in accordance with Section 7.11 hereof, and, subject to the terms and conditions of the applicable Third Party License Agreement regarding reimbursement of a Third-Party Licensor’s costs and expenses or sharing of recovery with a Third-Party Licensor, to settle and retain the proceeds of such actions. Each Licensor shall execute and deliver such additional documents and perform such additional acts as are necessary, to establish, perfect, enforce, evidence or otherwise protect NewCo’s rights under this Section 7.8. The Licensor obligations in this Section 7.8 shall apply to Exeter only to the extent that Exeter has or acquires the relevant prosecution, maintenance and enforcement rights with respect to its Licensed Patents.

7.9 Abandonment of Licensed Patents.

(a) Before NewCo elects not to file outside the United States or ceases prosecuting or maintaining, or otherwise allows abandonment of, any Licensed Patent in any jurisdiction, NewCo shall use commercially reasonable efforts to provide written notice to the Licensors no later than sixty (60) days prior to any abandonment of rights. Within thirty (30) days after receipt of such notice, the Licensor that contributed the Licensed Patent to NewCo may provide a reply notice to NewCo that the claims of the Licensed Patent have potential application outside of the Field and request transfer of control of such patent’s prosecution and maintenance of the Licensed Patent in the specified jurisdiction. (If such Licensor does not provide such a reply notice within thirty (30) days or does not take control of such patent’s prosecution and maintenance, NewCo may abandon such Licensed Patent or claims thereof without further obligation or liability to Licensor.) Subject to any requirements under applicable Third Party License Agreements regarding transfer to a Third-Party Licensor, NewCo shall thereafter and in a

timely manner so as to avoid any loss of rights, transfer control of such patent’s prosecution and maintenance in the specified jurisdiction to such Licensor. If required by the Third-Party License Agreements applicable to such Licensed Patent, NewCo shall also notify the Third-Party Licensor of such Licensed Patent and provide such Third-Party Licensor such rights as are specified in the Third-Party License Agreements; provided, however, that in the event that the Third-Party Licensor’s instructions are incompatible with the Licensor’s instructions, NewCo shall notify the Licensor and the Third-Party Licensor and then transfer control of such Licensed Patent’s prosecution and maintenance in the specified jurisdiction to the Third-Party Licensor accompanied by a copy of the Licensor’s instructions without further obligation or liability on the part of NewCo.

(b) Unless otherwise instructed by the Licensor, if the Licensor contributing such Licensed Patent requests that NewCo transfer control of the Licensed Patent to the Licensor in accordance with this Section 7.9, NewCo shall, within thirty (30) days thereafter, provide to the Licensor any patent and patent application files (including paper copies and, to the extent available, duplicate electronic copies), together with contact information for any outside counsel and any prosecution docket listings, whether maintained by outside counsel or internally at NewCo, including those listings containing information concerning outstanding due dates and deadlines, in each case associated with the Licensed Patent being transferred. In the event that a Licensor or Third-Party Licensor elects to have control of prosecution and maintenance of such Licensed Patent transferred to it in accordance with this Section, such Licensed Patent shall no longer be deemed licensed to NewCo under Article 2 in the applicable jurisdiction(s), except to the extent necessary to continue licensing such Licensed Patents under Pre-existing License Agreements and any sublicenses granted by NewCo before such transfer.

(c) Notwithstanding the foregoing, this Section 7.9 shall not apply in the event NewCo elects to not file, to cease prosecution or to abandon a patent application within the Licensed Patents (a “Subject Patent”) in favor of a continuation or divisional application or the jurisdictional equivalent thereof.

7.10 Transfer Back Costs. The obligation of NewCo to transfer control of prosecution and maintenance of any Licensed Patent as set forth in Section 7.9 shall be subject to the applicable Licensor or Third-Party Licensor agreeing to reimburse NewCo for any out-of-pocket direct costs, fees and other expenses reasonably incurred by NewCo with respect to any such Licensed Patent after the date of such Licensor’s written request to transfer control. Upon the effective transfer of control of any Licensed Patent to the applicable Licensor or Third-Party Licensor pursuant to this Section 7.10, such transferee shall be solely responsible for, and shall bear all costs and expenses associated with, the prosecution and maintenance relating to such Licensed Patent in the specified jurisdiction(s) arising thereafter.

7.11 Enforcement of Patent Rights. Each Party, first having knowledge of any of the following, shall notify the others in writing of any third party infringement or misappropriation of any Patents or of any Technology licensed to NewCo hereunder or any attempts to invalidate or render unenforceable any of such rights licensed hereunder including, without limitation, by declaratory judgment action or litigation.

(a) NewCo shall have the initial right, but not the obligation, as to all other Parties to institute, prosecute, defend and control any action, suit or proceeding (an “Action”) with respect to such infringement or misappropriation that includes infringing activities or use of misappropriated Technology within the Field or with respect to such attempts to invalidate or render unenforceable any such rights licensed hereunder, including any declaratory judgment action or litigation, at its expense. NewCo shall be entitled to use counsel of its choice and shall consult with and keep the other Parties and, to the extent contractually required by Third-Party License Agreements, the Third-Party Licensors, informed of the progress of the Action. All Parties shall cooperate reasonably with NewCo, at NewCo’s request, in connection with any such Action. For any Action involving any Licensed Patent having material applicability outside the Field, NewCo and the applicable Licensor shall mutually agree upon the strategy for enforcing (or defending) such Licensed Patent, and no settlement of or material concession with respect to such Action shall be made or entered into by NewCo without Licensor’s consent and no settlement of or material concession with respect to an Action involving any Licensed Patent having material applicability within the Field shall be made or entered into by Licensor without NewCo’s consent. Subject to the terms and conditions of the applicable Third Party License Agreement regarding reimbursement of a Third-Party Licensor’s costs and expenses or sharing of recovery with a Third-Party Licensor, any amounts recovered in such Action by NewCo shall (i) be used first to reimburse NewCo, then the Licensors and, if applicable, the Third-Party Licensors, for the costs and expenses reasonably incurred in connection with such Action (including attorneys and expert fees) and (ii) after such reimbursement, NewCo shall retain any remainder.

(b) Subject to the applicable terms and conditions of any Pre-existing License Agreements, NewCo shall have the right to delegate its right in accordance with Section 7.11(a) to institute, prosecute, defend and control any Action to any of its sublicensees which has received an exclusive sublicense pursuant to Section 4 of any or all rights granted to NewCo in Sections 2 and 3, provided that any such delegation shall be subject to such sublicensee agreeing in writing to be bound by all relevant obligations of NewCo under Section 7.11(a). Such sublicensee shall be entitled to use counsel of its choice and shall be required to keep the Parties and the Third-Party Licensors, to the extent contractually required, informed of the progress of the Action. The Parties shall cooperate reasonably with such sublicensee, at such sublicensee’s request, in connection with any such Action. Subject to the terms and conditions of the applicable Third Party License Agreement regarding reimbursement of a Third-Party Licensor’s costs and expenses or sharing of recovery with a Third-Party Licensor, any amounts recovered in such Action by such sublicensee shall (i) be used first to reimburse such Sublicensee, then NewCo, then the Licensors and, if applicable, the Third-Party Licensors, for the costs and expenses reasonably incurred in connection with such Action (including attorneys and expert fees), (ii) after such reimbursement, any remainder attributable to lost profits or a reasonable royalty on infringing sales shall be allocated to such sublicensee and (iii) after distribution under (i) and (ii) above, the remainder of any recovery shall be retained by NewCo and/or the sublicensee as may be agreed by NewCo and the sublicensee.

(c) Limitation on Prosecution Rights. To the extent any Licensor does not have the right to prosecute, maintain, enforce, defend, control or otherwise exercise the rights intended to be assigned to NewCo under this Section 7 with respect to any third-party Patents licensed to NewCo hereunder now or in the future, NewCo shall not have such rights or obligations with respect thereto. To the extent any Licensor has such right or benefit, but it is not assignable to NewCo or consent to such assignment is necessary but cannot be obtained, NewCo and the Licensor shall cooperate in a mutually agreeable arrangement under which NewCo will obtain the benefits thereunder, including, by way of example but not limitation, Licensor passing on NewCo’s comments during patent prosecution to such third-party to the extent that Licensor has the right to comment on patent prosecution and Licensor enforcing such rights for the benefit of NewCo under the Third-Party License Agreement, subject to any confidentiality obligations in the applicable Third-Party License Agreement.

8 OTHER RIGHTS AND OBLIGATIONS.

8.1 Commercialization Efforts. NewCo shall make commercially reasonable efforts to commercialize the Licensed Patents in accordance with the Annual Plan approved by its Board of Directors. Such efforts with respect to Third-Party Patents shall, at a minimum, comport with the level of diligence required by the applicable Third-Party Licensor under its Third-Party License Agreement.

8.2 [intentionally omitted]

8.3 No Obligation to Disclose to Other Licensors. Except as expressly set forth in this Agreement, nothing in this Agreement shall obligate, or be construed to obligate, any Licensor to disclose, explain or otherwise provide to any other Licensor any of such Licensor’s Technology.

8.4 [intentionally omitted]

8.5 Grantback Licenses to Licensors. To the extent necessary, NewCo shall grant, and hereby grants, to the applicable Licensor a non-exclusive, royalty-free license under any and all intellectual property rights or contractual rights assigned, conveyed and transferred by such Licensor to NewCo hereunder, of the scope necessary or useful for, but solely for the purpose of, such Licensor discharging its duties, obligations, and liabilities under any Pre-existing License Agreement. Such license shall be irrevocable for as long as both this Agreement and the applicable Pre-existing License Agreement remain in effect.

8.6 Grantback of Internal Research License to Licensors. NewCo hereby grants to each Licensor (solely for internal research and development use by Licensor and by Licensor’s development partners and collaborators) a nonexclusive, fully paid-up, royalty-free, non-transferable (except as permitted in Section 15.9) license, under the Licensed Patents and Technology Rights in the Licensor Technology and Third Party Technology licensed by such Licensor to NewCo hereunder, to practice such Licensed

Patents and Technology Rights in the Field solely for internal research and development of products or services outside of the Field.

8.7 Delegation. NewCo shall have the right to delegate any of its obligations and associated rights hereunder, in whole or in part, to the Manager (as defined in the Formation and Shareholders Agreement) for the purpose of performing the management services for NewCo, including without limitation the obligations to prosecute and maintain the Licensed Patents and the right to institute, prosecute and control any Action.

8.8 Prohibition on Human Cloning and Illegal Uses. NewCo acknowledges and agrees that it shall not exercise any rights under the Third-Party Patents licensed from Geron pursuant to the Xxxxx Xxxxxx Agreements or under the Third-Party Patents licensed from ELS pursuant to the Exeter Roslin Agreement for the uterine implantation and development of a reconstructed embryo with identical nuclear genetic information to another living or deceased human being or for the conduct of any experiments or any research which is illegal within the applicable territory as of the date on which such experiments and/or research are conducted.

8.9 Payments by NewCo to Licensors. NewCo shall pay to the applicable Licensor the royalties, minimum annual royalty payments, and maintenance fees and comply with the other payment obligations in each case as set forth in the Disclosure Schedule, accruing after the Effective Date under the applicable Third Party License Agreement. Where a Third-Party Licensor has agreed to accept direct payment by NewCo, NewCo may pay directly to such Third-Party Licensor on behalf of the applicable Licensor. Such payments shall be made in a timely manner as specified in the applicable Third-Party License Agreement. Along with payment, NewCo will provide a statement showing the calculation used to determine the amount owed and such additional information required in the Disclosure Schedule, if any. Licensors shall not amend, or permit to be amended, the Third-Party License Agreements in a manner that adversely affects the rights or benefits extended to or obligations imposed upon NewCo hereunder without the prior written consent of NewCo.

9 TERM AND TERMINATION.

9.1 Term. This Agreement shall be effective as of the Effective Date and shall continue in effect until terminated pursuant to Section 9.2.

9.2 Termination.

(a) The Parties may terminate this Agreement upon the mutual written agreement of all Parties.

(b) This Agreement shall automatically terminate on the effective date of the dissolution and/or liquidation of NewCo pursuant to Section 6.6 (deadlock) or 8.3(b) (shareholder bankruptcy) of the Formation and Shareholders Agreement.

(c) NewCo may terminate this Agreement without cause by providing ninety (90) days’ prior written notice thereof to the Licensors, but such notice may only

be provided after such time as all of the outstanding Securities (as such term is defined in the Formation and Shareholders Agreement) of either Licensor have been acquired by the other Licensor (and/or its Affiliates or permitted third parties).

(d) For the avoidance of doubt, without limiting Sections 8.2(b) and 8.3(a) of the Formation and Shareholders Agreement (which set forth certain rights triggered by breach of this Agreement), breach or default of any provision of this Agreement by any Party hereto shall not be grounds for termination of this Agreement or suspension of any right or the performance of any obligation or duty created by this Agreement by any Party.

9.3 Continuing Liability; Survival. Termination of this Agreement for any reason shall not release any Party from any liability or obligation which has already accrued as of the effective date of such termination, and shall not constitute a waiver or release of, or otherwise be deemed to prejudice or adversely affect, any rights, remedies or claims, whether for damages or otherwise, which a Party may have hereunder, at law, equity or otherwise or which may arise out of or in connection with such termination. The rights and obligations of the Parties under the following Sections shall survive any termination or expiration of this Agreement: 1 (Definitions), 9.3 (Continuing Liability; Survival), 9.4 (Return of Confidential Information), 9.7 (Survival of NewCo Sublicenses), 9.8 (Prosecution Transition), 11 (Disclaimer), 12 (Limitation of Liability), 13 (Indemnification), 14 (Confidentiality) and 15 (Miscellaneous).

9.4 Return of Confidential Information. Upon the termination of this Agreement, each Recipient, at its own cost, shall promptly return to the Discloser any and all documents and materials constituting or containing Confidential Information of the Discloser which are in its possession or control, or at the Discloser’s option, shall destroy such documents and materials and certify such destruction in writing to the Discloser, provided that NewCo may retain a copy of and use such items as reasonably necessary to perform its obligations under Sections 9.7 and 9.8 and to comply with tax and accounting laws and obligations, and each Recipient may retain a copy of such items and use it solely to serve as a record of its compliance with this Agreement.

9.5 Right to Cure. Without limiting any of their obligations under Section 10.4, if any Licensor (i) receives a notice of any alleged or suspected breach by such Licensor of any Third-Party License Agreement, or (ii) concludes without such a notice that such a breach has occurred, such Licensor shall promptly notify NewCo in writing and shall use its best efforts to cure any such breach. Notwithstanding the foregoing, NewCo shall be entitled, but not obligated, to cure any alleged breach by such Licensor of such Third-Party License Agreement and set-off the cost of such cure against amounts otherwise owed or payable to such Licensor by NewCo.

9.6 Partial Termination Right. Upon termination of either of the CT Agreement (unless ELS obtains a direct license from UMass of the UMass Third-Party Patents and Third-Party Technology) or the Exeter Roslin Agreement or either of the Xxxxx Xxxxxx Agreements or (to the extent NewCo then has an effective sublicense thereunder) any other Third-Party License Agreement, NewCo shall have the right to

terminate this Agreement only with respect to the Third-Party Patents and Third-Party Technology affected by termination of such Third-Party License Agreement (or with respect to intellectual property jointly owned by a Licensor and a Third-Party Licensor, such Third-Party Licensor’s interest in such intellectual property), effective immediately on notice to the applicable Licensor, without prejudice to any rights that may survive such termination pursuant to this Agreement or any agreement with a Third-Party Licensor.

9.7 Survival of NewCo Sublicenses. In the event that NewCo has granted any sublicenses hereunder (“NewCo Sublicenses”) and this Agreement subsequently terminates in accordance with the provisions of Section 9, the Licensors acknowledge and agree that the sublicensees (“NewCo Sublicensees”) of such NewCo Sublicenses shall retain their licensed rights as follows. The Licensors agree that, effective as of the date of such termination, the licenses granted under any NewCo Sublicenses shall survive to the extent such licenses relate to a Licensor’s rights to Third-Party Patents, Third-Party Technology, Licensor Patents, and/or Licensor Technology, provided that the applicable NewCo Sublicensee (i) continues to make all payments thereafter that would have been owed by such NewCo Sublicensee to NewCo for the license to such Licensor’s rights in accordance with the applicable NewCo Sublicense and (ii) continues to comply with its other obligations under its NewCo Sublicense with respect to such Licensor’s rights. Absent any agreement by the Licensors to the contrary at such time, all amounts payable thereafter by the NewCo Sublicensees under the NewCo Sublicenses shall be applied first to pay any amounts owed to any third-party licensors of NewCo (other than the Licensors) for rights licensed under and as a result of such NewCo Sublicense and any remaining amounts shall be shared pro rata thereafter by the Licensors based on their respective percentage ownership of NewCo Securities immediately prior to the effective termination date of this Agreement. Subject to any applicable payment arrangements prescribed by the Third-Party License Agreements, the NewCo Sublicensees shall be instructed to pay all amounts to the Licensor holding the larger percentage ownership interest in NewCo and such Licensor shall be responsible for remitting from such amounts any amounts payable to the third-party licensors and to the other Licensor, accompanied by an explanatory statement. For the avoidance of doubt, the sublicensees shall not be liable for any payments that may be owed by NewCo or for performing any other obligations of NewCo to the Licensors under this Agreement.

9.8 Prosecution Transition. Subject to the last sentence of this Section 9.8, upon any termination of this Agreement, NewCo shall, at its sole expense, for a period of ninety (90) days after termination (“Termination Transition Period”), (a) continue to prosecute and maintain the Licensed Patents in the ordinary course, consulting closely with and complying with the instructions of the applicable Licensor with respect to any filings or communications with patent authorities during such period, (b) permit the applicable Licensor ample opportunity to comment on any filings and communications with patent authorities during such period prior to submission; and (c) not abandon the prosecution of such patents and patent applications or any claims unless at NewCo’s written direction. NewCo shall provide to each Licensor, within thirty (30) days after termination, all patent and patent application files (including paper copies and, to the extent available, electronic copies) transferred from its outside counsel (or from NewCo

if handled internally), unless instructed by such Licensor otherwise. Notwithstanding the foregoing, on partial termination of this Agreement by NewCo pursuant to Section 9.6, NewCo shall have the right to retain its prosecution, maintenance and other rights under Section 7 to the extent the applicable Third-Party Licensor agrees thereto.

EXCEPT AS PROVIDED IN SECTION 10, NO PARTY MAKES ANY REPRESENTATIONS OR WARRANTIES UNDER OR RELATING TO THIS AGREEMENT OR THE SUBJECT MATTER HEREOF (INCLUDING, WITHOUT LIMITATION, ITS TECHNOLOGY OR THE VALIDITY OF ANY PATENT). THE PARTIES HEREBY DISCLAIM ANY AND ALL OTHER REPRESENTATIONS AND WARRANTIES OF ANY KIND, WHETHER EXPRESS, IMPLIED OR STATUTORY, WITH RESPECT TO THIS AGREEMENT OR THE SUBJECT MATTER HEREOF, INCLUDING (WITHOUT LIMITATION) ANY WARRANTY OF ACCURACY, TITLE, NON-INFRINGEMENT, FITNESS FOR A PARTICULAR PURPOSE, AND MERCHANTABILITY AND ANY AND ALL WARRANTIES THAT MAY ARISE FROM COURSE OF DEALING, COURSE OF PERFORMANCE OR USAGE OF TRADE.

13 INDEMNIFICATION.

13.1 Indemnification Obligations. Each Party shall indemnify, defend and hold harmless each of the other Parties, their Affiliates, successors and assigns and their respective directors, officers, employees and agents from and against any and all liabilities, damages, losses, settlements, penalties, fines, costs and expenses, including, without limitation, reasonable attorneys’ fees (any of the foregoing to be referred to herein as “Damages”) of whatever kind or nature (but not including taxes), to the extent arising from any third party claim, action, suit or proceeding based on any breach of such Party’s representations, warranties or covenants as set forth in this Agreement, except to the extent attributable to a material breach by any other Party of any term of this Agreement.

13.2 NewCo Indemnification Obligations. NewCo shall indemnify, defend and hold harmless each of the Licensors, their Affiliates, successors and assigns and their respective directors, officers, employees and agents from and against any and all Damages of whatever kind or nature (but not including taxes), to the extent arising from any third party claim, action, suit or proceeding based on the exercise by (i) NewCo or (ii) a NewCo sublicensee of any or all of the rights granted to NewCo in Sections 2 and 3 pursuant to a sublicense granted by NewCo under Section 4 of those rights, except to the extent attributable to a material breach by any Licensor(s) of any term of this Agreement.

Each Party shall cooperate with the other Party and its counsel in the course of the defense of any such suit, claim, action, proceeding or demand, such cooperation to

include, without limitation, using reasonable efforts to provide or make available documents, information and witnesses.

14 CONFIDENTIALITY.

14.1 Confidential Information. The Parties recognize that, in connection with the performance of this Agreement, each Discloser may disclose “Confidential Information” (as defined below) to the other Recipients. For purposes of this Agreement “Confidential Information” means (i) proprietary information (whether owned by the Discloser or a third party to whom the Discloser owes a nondisclosure obligation) that is marked as confidential at the time of disclosure to the Recipient, or if in oral or in other intangible form or in any form that is not so marked, that is identified as confidential at the time of such disclosure and summarized in writing and transmitted to the Recipient within thirty (30) days of such disclosure; and (ii) all unpublished invention disclosures or patent applications and patent application file histories disclosed by a Licensor in any form to NewCo. “Confidential Information” shall not include information which: (A) was known to the Recipient at the time of the disclosure by the Discloser as indicated by the Recipient’s contemporaneous written records; (B) has become publicly known through no wrongful act of the Recipient; (C) has rightfully been received by the Recipient from a third party without a duty of confidentiality; or (D) was independently developed by the Recipient without reference to the Discloser’s Confidential Information. The Recipient agrees (x) not to use any such Confidential Information for any purpose other than in the performance of its obligations or exercise of its rights under this Agreement or any Transaction Document and (y) not to disclose any such Confidential Information, except (1) to its employees, contractors, or other bona fide commercial partners who are reasonably required to have the Confidential Information in connection herewith or with any of the other Transaction Documents; (2) to its agents, representatives, lawyers, accounting firms, and other advisers that have a need to know such Confidential Information; (3) to Persons in connection with a financing, strategic partnership, merger, acquisition, investment or proposed financing, strategic partnership, merger, acquisition or investment, where such Persons are subject to an obligation of confidentiality at least comparable to that set forth in this Section 14.1, (4) to sublicensees, in accordance with Section 4; (5) to third parties with whom Recipient is in good faith discussions relating to entering into a sublicense relationship; (6) to patent authorities and foreign patent associates and agents in NewCo’s exercise of its rights and performance of its obligations pursuant to Section 7; (7) pursuant to, and to the extent of, a request or order by a Governmental Authority, provided, however, that prior to any such requested or ordered disclosure, Recipient shall give the Discloser reasonable advance notice of any such disclosure and shall cooperate with Discloser in protecting against any such disclosure and/or obtaining a protective order narrowing the scope of such disclosure and/or use of the Confidential Information of Discloser; and/or (8) to the extent authorized by the Discloser in advance in writing. The Recipient shall take the same degree of care that it uses to protect its own confidential and proprietary information and materials of similar nature and importance (but in no event less than reasonable care) to protect the confidentiality and avoid the unauthorized use or disclosure of the Confidential Information of the Discloser.

14.2 Terms of Agreement. Each Party agrees that the terms and conditions of this Agreement and the Transaction Documents shall be treated as confidential information and that no reference thereto shall be made without the prior written consent of the other Parties (which consent shall not be unreasonably withheld) except (a) as required by applicable law including, without limitation, by the Securities and Exchange Commission (“SEC”), (b) to its accountants, banks, financing sources, lawyers and other professional advisors, provided that such parties undertake in writing (or are otherwise bound by rules of professional conduct) to keep such information strictly confidential, (c) in connection with the enforcement of this Agreement, and (d) in connection with a financing, strategic partnership, merger, acquisition or proposed financing, strategic partnership, merger or acquisition. The Parties will consult with each other, in advance, with regard to the terms of all proposed press releases, public announcements and other public statements with respect to the transactions contemplated hereby. For the avoidance of doubt, the Parties acknowledge and agree that Geron may disclose this Agreement to the SEC, provided Geron seeks confidential treatment of confidential information contained herein identified by any Party.

14.3 Remedies. Each Party acknowledges and agrees that (i) its obligations under this Section 14 are necessary and reasonable to protect the other Parties and each of the other Parties’ businesses, (ii) any violation of these provisions could cause irreparable injury to the other Parties for which money damages would be inadequate, and (iii) as a result, the other Parties shall be entitled to injunctive relief against a breach or a threatened breach of the provisions of this Section 14 without the necessity of proving actual damages. The Parties agree that the remedy set forth in this Section 14 is in addition to and in no way preclude any other remedies or actions that may be available under this Agreement or under applicable law.

15.3 Severability. If any provision in this Agreement shall be found or be held to be invalid or unenforceable then the meaning of said provision shall be construed, to the extent feasible, so as to render the provision enforceable, and if no feasible interpretation would save such provision, it shall be severed from the remainder of this Agreement which shall remain in full force and effect unless the severed provision is essential and materially changes the economic benefit of this Agreement to any Party. In such event, the Parties shall use best efforts to negotiate, in good faith, a substitute, valid and enforceable provision or agreement which most nearly effects the Parties’ intent in entering into this Agreement. Notwithstanding the foregoing, if any provision of this Agreement is held to be invalid or unenforceable, the remaining provisions of this Agreement shall remain in full force and effect.

15.4 References; Subject Headings. The article, section and paragraph headings contained herein are for the purposes of convenience only and are not intended

15.6 Expenses. Each of the Parties will bear its own costs and expenses, including, without limitation, fees and expenses of legal counsel used or hired in connection with the negotiation and preparation of this Agreement.

15.7 No Waiver. No waiver of any term or condition of this Agreement shall be valid or binding on a Party unless the same shall have been set forth in a written document, specifically referring to this Agreement and duly signed by the waiving Party. The failure of a Party to enforce at any time any of the provisions of this Agreement, or the failure to require at any time performance by one or both of the other Parties of any of the provisions of this Agreement, shall in no way be construed to be a present or future waiver of such provisions, nor in any way affect the ability of a Party to enforce each and every such provision thereafter.

15.8 Entire Agreement; Amendments. The terms and conditions contained in this Agreement (including the Exhibits hereto) and the Transaction Documents, together with any other written agreements executed contemporaneously herewith, constitute the entire agreement between the Parties and supersede all previous and contemporaneous agreements and understandings, whether oral or written, between the Parties with respect to the subject matter hereof. No agreement or understanding amending this Agreement shall be binding upon any Party unless set forth in a written document which expressly refers to this Agreement and which is signed and delivered by duly authorized representatives of each Party.

15.9 Assignment. The Parties agree that this Agreement and any of the Parties’ rights and obligations hereunder may not be transferred or assigned, by contract, operation of law or otherwise, (hereafter “assign”) to a third party without the prior written consent of the other Parties hereto, which consent shall not unreasonably be withheld. Notwithstanding the foregoing, a Party may assign this Agreement and all of its rights and obligations hereunder without consent of the other Parties to (i) its Affiliates, and (ii) to the surviving or acquiring entity in connection with a Change of Control; provided that any such assignee agrees in writing to be bound by the terms and conditions of, and assumes in writing all obligations and liabilities under, this Agreement and in the event that a Licensor assigns this Agreement, the Licensor may only assign together with an assignment of all rights licensed to NewCo hereunder. Any assignment not in conformance with this Section 15.9 shall be null, void and of no legal effect. This Agreement shall inure to the benefit of, and shall be binding upon, the Parties and their respective permitted successors and assigns.

15.10 Independent Contractors. The relationship of the Parties established by this Agreement is that of independent contractors. Nothing in this Agreement shall be construed to create any agency or other relationship between or among any of the Parties.

15.11 No Beneficiaries. Nothing herein express or implied, is intended to or shall be construed to confer upon or give to any person, firm, corporation or legal entity, other than the Parties and their Affiliates who hold Securities, any interests, rights, remedies or other benefits with respect to or in connection with any agreement or provision contained herein or contemplated hereby.

15.12 Effectiveness. This Agreement, if signed by a duly authorized representative of each Party, shall be effective as of the Effective Date.

15.13 Counterparts. This Agreement may be executed in any number of counterparts, and each counterpart shall constitute an original instrument, but all such separate counterparts shall constitute only one and the same instrument.

15.14 Public Announcements. Any public announcement concerning this Agreement or the subject matter hereof shall be subject to the prior written consent of ALL Parties. Such consent shall not be unreasonably withheld or delayed by ANY Party. Prior to any such public announcement, the Party wishing to make the announcement will submit a draft of the proposed announcement to the other Parties in sufficient time to enable the other Parties to consider and comment thereon.

15.15 Dispute Resolution. Any dispute, controversy, or claim arising out of or related to this Agreement or to the breach, termination, or invalidity thereof (each a “Dispute”) shall be solely and exclusively settled by confidential, binding arbitration in accordance with the then-current commercial arbitration rules of the American Arbitration Association, subject to the terms and conditions of this Section 15.15. The Parties agree that prior to initiating any arbitration proceedings against the other(s) with respect to any Dispute, they will follow the procedures set forth in this Section 15.15 in an attempt to resolve such Dispute.

(a) Executive Negotiations. In the event of a Dispute, any Party may provide written notice to the other Parties describing such Dispute and a proposed resolution in reasonable detail “Resolution Notice”). The president or CEO of each Party involved in the Dispute, or their respective designees who shall have the authority to resolve such Dispute, shall attempt to resolve such Dispute through good faith negotiations. If any Dispute cannot be settled by agreement of the involved Parties pursuant to the preceding sentence within sixty (60) days after receipt of the Resolution Notice (“Negotiation Period”), then any Party may, by written notice to the other(s) requesting resolution by arbitration (“Arbitration Demand”), invoke the dispute resolution provisions of Section 15.15(b).

(b) Arbitration. Any Dispute subject to arbitration under this Agreement shall be adjudicated by three (3) neutral and impartial arbitrators. In the event that only two Parties are parties to the dispute, each Party shall appoint one arbitrator

within thirty (30) days after the other Party’s receipt of the Arbitration Demand, and the two arbitrators so appointed will then, within ninety (90) days of the receipt of the Arbitration Demand, jointly appoint the third arbitrator, who shall serve as chairperson of the arbitration tribunal; provided that if the two arbitrators cannot agree within such period on a third arbitrator, the American Arbitration Association shall appoint the third arbitrator. In the event that three Parties are parties to the dispute, each Party shall appoint one arbitrator within thirty (30) days after the last date of receipt of the Arbitration Demand by a Party (other than the Party submitting such demand) and the American Arbitration Association shall appoint one of them to serve as chairperson of the arbitration tribunal. The decision of the arbitration tribunal shall be final and binding upon the parties to the dispute, and may be entered in any competent court for judicial acceptance of such an award and order of enforcement. All costs of the arbitration and arbitrators shall be shared equally by the parties to the dispute, but each Party shall be responsible for the costs of its own legal and other representatives and witnesses. The arbitrators shall not have the right or authority to award punitive damages to any Party. Arbitration will take place in Phoenix, Arizona. The Parties agree that the arbitration proceedings and its contents shall be kept confidential, except as may otherwise be required by applicable law.

(c) Injunctive Relief. Notwithstanding anything to the contrary in this Section 15.15, each Party may, and expressly reserves the right to, seek judicial relief from any court of competent jurisdiction in order to obtain an injunction or other equitable relief or to enforce the provisions of Section 14 or to otherwise obtain temporary relief pending the outcome of the arbitration for breaches or threatened breaches of this Agreement by any Party which have the potential to cause irreparable injury to the other Party(ies). Examples of such breaches include, without limitation, breaches of confidentiality obligations, use of technology outside the scope of the licenses granted herein, actions or omissions with respect to Licensor’s obligations relating to Third-Party License Agreements and Pre-existing License Agreements and breach of Licensor obligations with respect to Adversarial Actions or other challenges to the Licensed Patents.

15.16 Ambiguities. Ambiguities, if any, in this Agreement shall not be construed against any Party, regardless of which Party may be deemed to have authored the ambiguous provision.
