Re: Amendment and Stand-by License Arrangement with Novartis Institutes for BioMedical Research, Inc. (“NVS”)

Ladies and Gentlemen:

Reference is hereby made to that certain License Agreement dated September 14, 2016 by and between Homology Medicines, Inc. (“HMI”) and the California Institute of Technology (“Caltech”), as amended by the First Amendment to License Agreement dated May 16, 2017 (the “Caltech-HMI License”). All capitalized terms used but not defined herein will have the meaning set forth in the Caltech-HMI License.

This letter agreement (this “Letter Agreement”) serves as the second amendment to the Caltech-HMI License, effective on the date last signed below. HMI and Caltech agree as follows:

The fifth paragraph of Section 2.3 (Sublicensing) of the Caltech-HMI License is hereby deleted and replaced in its entirety with the following:

“Any sublicenses granted by Licensee shall survive termination of the licenses granted in Section 2.1 or termination of this Agreement, provided that the following conditions are met as of the date of such termination:

(a) the written agreement between Licensee and Sublicensee pursuant to which the sublicense was granted (i) [***], (ii) [***], and (iii) [***];

(b) Licensee informs the Sublicensee in writing (with a copy to Caltech) that the Sublicensee’s obligations pursuant to the foregoing clause (a) are in effect as a result of the termination; and

(c) the sublicense was granted in accordance with the sublicensing provisions of this Agreement.”

In addition, HMI proposes to enter into an agreement (the “Collaboration Agreement”) with NVS pursuant to which, among other things, HMI grants to NVS an exclusive sublicense of the rights licensed to HMI by Caltech under the Caltech-HMI License (the “Licensed Caltech Rights”) with respect to certain candidates and products (as defined under the Collaboration Agreement, “Candidates” and “Products”) as well as other patent rights and know-how controlled by HMI. As a condition to entering into the Collaboration Agreement, NVS has requested that Caltech and HMI memorialize, in this Letter Agreement, their agreement to the following:

 

1. Term. The following provisions of this Letter Agreement will be effective as of the date of this Letter Agreement, but will be null and void if the Collaboration Agreement is not executed by each of HMI and NVS within [***] days after the date of this Letter Agreement.

 

2. Approval of Sublicense; Delivery of Collaboration Agreement. Caltech hereby acknowledges that HMI may grant a sublicense of the Licensed Caltech Rights and stipulates that the version of the Collaboration Agreement provided to Caltech grants to NVS a sublicense of the Licensed Caltech Rights in accordance with the sublicensing provisions of the Caltech-HMI License, as required under Section 2.3 (Sublicensing) of the Caltech-HMI License (as amended pursuant to this Letter Agreement), and the parties agree that the final version of the Collaboration Agreement will remain consistent with Section 2.3 (Sublicensing) of the Caltech-HMI License. HMI will deliver to Caltech a true and complete copy of the Collaboration Agreement promptly following the execution thereof, which copy, notwithstanding to the contrary set forth in Section 2.3 (Sublicensing) of the Caltech-HMI License, may be redacted to remove any confidential, proprietary, or competitive information of HMI or NVS to the extent that such redactions do not impair Caltech’s ability to ensure that the Collaboration Agreement is consistent with the Caltech-HMI License.

 

3. No Breach. Caltech confirms that as of the date of this Letter Agreement: (a) the Caltech-HMI License remains in full force and effect; and (b) Caltech has not given any notice to HMI of any breach by HMI under the Caltech-HMI License.

 

4. Waiver of Sublicense Obligations.

 

  (a) Caltech hereby irrevocably waives [***] and confirms that HMI will be in compliance with [***].

  (b) Caltech hereby waives the requirement in [***], provided however, that:

 

  i. NVS and Caltech promptly execute an agreement memorializing Caltech’s adoption, as the licensor, of the sublicense to the Licensed Caltech Rights under the Collaboration Agreement should the licenses granted in Section 2.1 (Grant of Rights) of the Caltech-HMI License or the Caltech-HMI License terminate; and

 

  ii. in the event of a conflict between the terms, conditions or obligations under the Caltech-HMI License and the Collaboration Agreement (except as specifically waived under this Letter Agreement) with respect to the Licensed Caltech Rights, the terms of the Caltech-HMI License will prevail.

 

5. Assignment of Caltech-HMI License. Caltech agrees that if it assigns its rights under the Caltech-HMI License or any of the intellectual property licensed to HMI thereunder, then Caltech will cause the applicable assignee to be bound by the terms of this Letter Agreement applicable to Caltech.
