(b)If CRISPR notifies EC and Tracr that CRISPR desires to abandon or cease prosecution or maintenance of any patent application or patent within the CRISPR Patent Rights in any country, Tracr may, by written notice to EC and CRISPR, elect to continue prosecution and/or maintenance of any such patent application or patent, at its cost and expense and choice of counsel.

5.4 Cooperation. Each party agrees to cooperate fully in the preparation, filing, prosecution and maintenance of CRISPR Patent Rights and Overlapping Patent Rights under Section 5.3. Such cooperation includes, but is not limited to: (i) executing all papers and instruments, or requiring its employees or contractors, to execute such papers and instruments, so as to enable the other party or CRISPR to apply for and to prosecute patent applications in any country as permitted by Section 5.3, including, without limitation, any power of attorney or similar instrument appointing the attorneys of any law firm selected by CRISPR as EC’s representatives and attorneys of record with respect to the CRISPR Patent Rights or Overlapping

Patent Rights and any petition or submission to the USPTO or any foreign patent office requesting that the USPTO or such foreign patent office accept the attorneys of such CRISPR-selected law firm as EC’s representatives and attorneys of record with respect to the Patent Rights; (ii) promptly informing the other party and CRISPR of any matters coming to such party’s attention that may affect the preparation, filing, prosecution or maintenance of Patent Rights; and (iii) providing, at the expense of the party (or CRISPR, if applicable) controlling and managing the preparation, filing, prosecution and maintenance of the Patent Rights any requested evidence or testimony, whether oral or written, in connection with the prosecution and maintenance of the Patent Rights, including any Patent Proceedings. Tracr shall be responsible for paying all EC’s costs in assisting and cooperating with Tracr under this Section 5.4. Tracr acknowledges that any preparation, filing, prosecution and maintenance of Patent Rights will require co-operation between Tracr and the Joint Owners.

5.5 Infringement by Third Parties.

(a)In the event that either EC or Tracr becomes aware of any infringement or threatened infringement of the CRISPR Patent Rights in the CRISPR Field or Tracr Field by a Third Party of any Patent Right, such party shall promptly notify the other party in writing to that effect. Tracr acknowledges that, to the extent that it is legally permitted to do so, CRISPR has the first right to bring and control any action or proceeding with respect to infringement of any CRISPR Patent Right within the CRISPR Field or the Tracr Field, at its own expense and by counsel of its own choice, subject to Section 5.5(f) of this Agreement and Section 5.5(e) of the CRISPR License. If the infringement of the CRISPR Patent Rights relates to the Tracr Field, Tracr shall have the right if it chooses, to join the proceedings on its own accord, at its own expense, to be represented in any such action by counsel of its own choice, and to review and comment on any papers filed during such action. EC may, if she wishes, delegate the performance of any participation rights and activities under this Section 5.5(a) to ERS.

(b)If the infringement of the CRISPR Patent Rights is solely in the Tracr Field and not in the CRISPR Field, and CRISPR fails to bring any such action or proceeding with respect to infringement in the Tracr Field within (i) […***…] following the notice of alleged infringement or (ii) […***…] before the time limit, if any, set forth in the appropriate laws and regulations for the filing of such actions, whichever comes first, then Tracr shall have the right to bring and control any such action solely with respect to such infringement in the Tracr Field at its own expense and by counsel of its own choice. EC will at Tracr’s expense join and cooperate fully in such action if EC is required to do so by Tracr and shall request that CRISPR shall join and cooperate fully in such action if and to the extent appropriate, all at Tracr’s expense. Tracr shall keep EC and CRISPR fully informed and up to date with respect to such infringement actions and shall take into account any reasonable suggestions made by EC or CRISPR. EC shall have the right if she chooses, to join the proceedings on her own accord, at her own expense, to be represented in any such action by counsel of her own choice, and to review and comment on any papers filed during such action. EC may, if she wishes, delegate the performance of any participation rights and activities under this Section 5.5(b) to ERS.

(c)Tracr shall notify EC within […***…] of becoming entitled to bring an action or proceeding pursuant to Section 5.5(b) as to whether or not Tracr will bring such action or proceeding. If Tracr notifies EC that Tracr will not bring such an action, or if Tracr fails to

provide any notice to EC within such period, then EC shall have the right to bring and control any such action at her own expense and by counsel of her own choice. Tracr will at EC’s expense join and cooperate fully in such action if Tracr is required to do so by EC. EC shall keep Tracr and CRISPR fully informed and up to date with respect to such infringement actions and shall take into account any reasonable suggestions made by Tracr or CRISPR. Each of Tracr and CRISPR shall have the right if it chooses, to join the proceedings on its own accord, at its own expense, to be represented in any such action by counsel of its own choice, and to review and comment on any papers filed during such action. Notwithstanding any other provision of this Article 5 to the contrary, EC’s rights under this Section 5.5(c) shall be exercisable only by EC and may not be extended to ERS.

(d)In the event EC brings any infringement action in accordance with Section 5.5(c), Tracr shall cooperate fully, including, if required to bring such action, the furnishing of a power of attorney or being named as a party.

(e)Neither party shall have the right to settle any patent infringement litigation under this Section 5.5 without the prior written consent of the other party, which shall not be unreasonably withheld. Except as otherwise agreed by the parties in connection with a cost-sharing arrangement, any recovery realized by a party as a result of any action or proceeding pursuant to this Section 5.5, whether by way of settlement or otherwise, after reimbursement of any litigation expenses of the parties, shall be retained by the party that brought and controlled such action for purposes of this Agreement;provided, however, that any recovery realized by Tracr as a result of any action brought and controlled by Tracr pursuant to Section 5.5(b) with respect to infringement in the Tracr Field, after reimbursement of the parties’ litigation expenses, shall be treated as Sublicensing Revenues for purposes of Section 3.3.

(f)To the extent that any infringement of the CRISPR Patent Rights or the Overlapping Patent Rights relates to both the CRISPR Field and the Tracr Field, Tracr shall agree a coordinated approach with CRISPR, and Tracr and CRISPR shall cooperate with respect to any enforcement proceedings. In respect of any proceedings brought by Tracr and CRISPR in cooperation as referred to in this Section 5.5(f), Tracr shall keep EC fully informed and up to date and shall take into account any reasonable suggestions made by EC.

(g)Defense of the validity or enforceability of any claim of the CRISPR Patent Rights asserted in an infringement action under this Section 5.5 shall be at the sole expense and control of the party bringing the infringement action, subject to the provisions of Article 9; andprovided, however, that each party shall reasonably inform the other and CRISPR and consider the other’s and CRISPR’s input.

(h)For clarity, except as expressly set forth in Section 5.5(f), Tracr’s enforcement rights under this Section 5.5 apply solely to CRISPR Patent Rights, and Tracr shall have no right to enforce Overlapping Patent Rights (other than in cooperation with CRISPR pursuant to Section 5.5(f)) or ERS Patent Rights.

5.6 Third Party Infringement Claims. Each party shall promptly notify the other party in writing of any allegation by a Third Party that the activity of either of the parties pursuant to this Agreement infringes or may infringe the intellectual property rights of such

Third Party. EC shall have the sole right to control any defense of any such claim involving alleged infringement of Third Party rights by EC’s activities at her own expense and by counsel of her own choice. Tracr shall have the sole right to control any defense of any such claim involving alleged infringement of Third Party rights by Tracr’s activities at its own expense and by counsel of its own choice. Neither party shall have the right to settle any patent infringement litigation under this Section 5.6 in a manner that diminishes the rights or interests of the other party or of CRISPR without the written consent of such other party and CRISPR (which shall not be unreasonably withheld).

5.7 Tracr Affiliates and Assignees. The parties agree that, at Tracr’s discretion, Tracr’s rights under this Article 5 may be exercised on behalf of Tracr by any Affiliated Sublicensee designated by Tracr from time to time.

5.8 Legal Inability to Exercise Rights. Tracr acknowledges that EC shall not be liable to Tracr if Tracr is unable as a matter of law to control filing, prosecution, maintenance, enforcement and defense of one or more of the Patent Rights in any country.
