This First Amendment to the License Agreement (the “First Amendment”) is made and entered into as of September 20, 2016 (the “First Amendment Effective Date”) by and between Sangamo BioSciences, Inc., a Delaware corporation having its principal place of business at Point Richmond Tech Center, 000 Xxxxx Xxxxxxxxx, Xxxxx X000, Xxxxxxxx, Xxxxxxxxxx 00000 (“Sangamo”), and Open Monoclonal Technology, Inc., a Delaware corporation with offices at 0000 Xxxxxxxx Xxxxxx Xxxxxxxxx, Xxxxx 000, Xxx Xxxxx, XX 00000 (“OMT”). OMT and Sangamo are individually referred to herein as a “Party” or collectively as the “Parties”.

Recitals

A. OMT and Sangamo are parties to a License Agreement effective as of April 2, 2008, as modified by that certain letter agreement dated October 1, 2008 (the “Agreement”), under which Sangamo granted to OMT a license to use, for the purpose of producing antibodies for clinical and commercial purposes, certain genetically modified rats that were generated using Sangamo’s proprietary zinc finger protein technology.

B. OMT and Sangamo desire to amend the Agreement in accordance with Section 10.7 of the Agreement to expand the scope of the license to include a new antibody-producing rat with an additional genetic modification generated using Sangamo’s proprietary zinc finger protein technology, under the terms and conditions of this First Amendment as set out herein.

Now, Therefore, the Parties agree as follows:

1. First Amendment of the Agreement

The parties hereby agree to amend the terms of the Agreement as provided below, effective as of the First Amendment Effective Date.

“1.27 “Aire-KO Rat” means (a) a rat having a genomic modification at the Aire Locus, which genomic modification (i) was created using ZFPs pursuant to a research license from Sigma’s sublicensee Sage Labs, Inc. and (ii) results in eliminated or significantly reduced expression of the Aire Gene or the expression by the Aire Gene of a protein with significantly reduced function, and (b) any progeny thereof.”

1.5 The following new Section 1.28 shall be added to read in its entirety as follows:

“1.28 “Aire Locus” means the location of the Aire Gene in the rat genome defined by the following NCBI reference location: [***].”

1.6 The following new Section 1.29 shall be added to read in its entirety as follows:

“1.29 “Discovery” means that the therapeutic entity is not introduced artificially into the animal but rather is a product of endogenous processes that occur within the animal (albeit genetically modified) and whose exact chemical structure could not have been predicted a priori (e.g., an antibody).”

1.7 The following new Section 1.30 shall be added to read in its entirety as follows:

“1.30 “DKO Product” means any OMT Product wherein the relevant Modified Rat is a DKO Rat.”

therapeutic can be made, and (b) any progeny or components thereof or any biological material derived therefrom other than DKO Products.”

1.9 The following new Section 1.32 shall be added to read in its entirety as follows:

“1.32 “Modified Animal” means a multicellular non-human animal, or tissues or organs from such an animal, the genome or genetic composition of which has been modified through the use (whether directly or indirectly) of a ZFP.”

“2.1 Licenses to OMT. Subject to the terms and conditions of this Agreement, Sangamo agrees to grant to OMT a royalty-bearing, worldwide, non-exclusive license under the Sangamo Technology to use, distribute, reproduce, modify (without the use of ZFN Deliverables) and sell Modified Rats solely for the purpose of making, using and selling OMT Products. Notwithstanding anything to the contrary in this Agreement, such license (a) does not include a license with respect to any genomic modifications that may be present in a Modified Rat that do not arise from or relate to a modification of the Target or the Aire Gene at the Aire Locus, (b) does not include any rights to any ZFPs and (c) does not include any rights to create or use DKO Rats for any purpose other than the Discovery or creation of new therapeutics, including creation of novel therapeutics through the DKO Rat’s response to stimuli. Sangamo shall not (nor shall it authorize or assist any Third Party to) develop, use or transfer a ZFN Deliverable for the benefit of itself or any Third Party for use in connection with (whether directly or indirectly) inactivation of rat immunoglobulin expression in rat cells, tissues or whole animals for any purpose other than non-commercial research purposes provided, however, that OMT’s sole remedy for any material breach of this covenant by Sangamo or its Affiliates shall be termination of the OMT’s payment obligations set forth in Section 3 below.”
