COMPANY shall use its reasonable endeavours to revert to ROTHAMSTED at least [***] prior to any applicable, procedural, regulatory or statutory deadline, it being agreed that ROTHAMSTED may proceed at its discretion if COMPANY has not actively participated in the consultation by such time. ROTHAMSTED will instruct its counsel to communicate directly with patent counsel for

COMPANY, and to fully consider any suggestions or revisions that would tend to support or expand the scope of claims sought, provided counsel was qualified to practice in the relevant jurisdiction (it being understood that the USA shall be considered a single jurisdiction for the purposes of this section). However, any actions or revisions that would tend to narrow the scope of claims sought would be subject to approval by ROTHAMSTED. If ROTHAMSTED wishes to abandon any patent or patent application within the OPTION PATENT RIGHTS, ROTHAMSTED shall provide COMPANY with reasonable prior notice of the intended abandonment, and assign such right to COMPANY, which may elect, at its expense, to PROSECUTE the relevant OPTION PATENT RIGHTS with no further license or royalty obligations to ROTHAMSTED with respect to such OPTION PATENT RIGHTS. COMPANY shall cooperate with ROTHAMSTED in such PROSECUTION. COMPANY agrees to hold any information provided to it under this Section 4.02 confidential in accordance with Section 6.05 and to use the information provided by ROTHAMSTED only for the purpose of advancing the OPTION PATENT RIGHTS and shall return all such information to ROTHAMSTED if the PARTIES do not complete the LICENSE AGREEMENT.

Any purported sale, transfer or assignment without ROTHAMSTED’s prior written consent shall be void ab initio, and this AGREEMENT shall immediately terminate. For purposes of this Section 6.09, “transfer” shall include any transfer by operation of law or otherwise. Notwithstanding the foregoing, COMPANY may assign this AGREEMENT without ROTHAMSTED’S consent (a) to an AFFILIATE of the COMPANY, or (b) pursuant to an acquisition or sale of all or substantially all its business to which the TECHNOLOGY relates.

Section 6.10 Notices. All notices under this AGREEMENT shall be deemed to have been fully given when done in writing and deposited in the United Kingdom or United States mail (whichever is relevant), registered or certified, and addressed as follows:

No such failure or waiver in writing by any one of the PARTIES hereto with respect to any rights, shall extend to or affect any subsequent breach or impair any right consequent thereon. The failure on the part of either PARTY to exercise or enforce any right conferred upon it hereunder shall not be deemed to be a waiver of any such right nor operate to bar the exercise or enforcement thereof at any time or times thereafter.

IN WITNESS WHEREOF, the PARTIES hereto have executed this AGREEMENT in duplicate originals by their duly authorized officers or representatives.

Upon exercise of the OPTION by COMPANY in Section 2.02 of this AGREEMENT, COMPANY and ROTHAMSTED will negotiate in good faith to agree and execute a definitive licensing agreement for the TECHNOLOGY as set forth in Section 2.03 of this AGREEMENT. The intent of this Appendix B is to describe certain items of the proposed agreement between the PARTIES. The PARTIES recognize that the verbiage on the items listed below must be negotiated and is contingent upon legal review and approval. This APPENDIX B does not contain all matters upon which agreement must be reached and is not intended to be a binding or enforceable agreement. A binding and enforceable agreement will not occur unless and until all necessary management/corporate approvals have been obtained and the PARTIES have negotiated, duly authorized, approved, executed and delivered the appropriate definitive agreements and all conditions therein have been satisfied or waived.

License Execution fee:

[***]

[***]

Sub-Licensing Royalty:

A sublicensing royalty of [***] of all sublicensing revenue received by COMPANY.

Royalty Stacking and Combination Products language:

Anti-stacking Deduction. In the event that COMPANY is legally required to make running royalty payments to one or more third parties for license(s) of third party intellectual property rights necessary or useful to making, using, offering for sale, selling or importing a given LICENSED PRODUCT, COMPANY may deduct up to [***] of such third-party royalties from any running royalty payments that are due to ROTHAMSTED under Section 4.3 on Yield10 Net Sales of such Licensed Product in the same Royalty Period. However, in no event will royalties to ROTHAMSTED be reduced to less than [***] of the applicable amounts set forth under Section entitled “Sales/Earned/Running Royalties” above. Upon request by ROTHAMSTED, COMPANY shall provide ROTHAMSTED with such records, information or access to personnel as are necessary to account for such third party royalties triggering the anti-stacking deduction, subject always to COMPANY remaining compliant with all applicable laws and obligations towards third parties.

Royalty Adjustment for Combination Product. Royalties payable under the section entitled “Sales/Earned/Running Royalties” above on COMPANY net sales of Combination Products will be reduced as follows. The royalty shall [***] However, in no event will royalties to ROTHAMSTED be reduced to less than [***] of the applicable amounts set forth set forth under the section entitled “Sales/Earned/Running Royalties” above for Combination Product Net Sales for any reason. Such adjustment cannot be made together with an anti-stacking deduction under the Section entitled “Anti-stacking Deduction” above. If the adjustment factor above cannot be

calculated for any reason the PARTIES will negotiate in good faith an alternative mechanism for an equitable adjustment of the running royalties payable on COMPANY net sales of the Combination Products. This provision does not apply to the royalty on Sublicensee net sales. As used herein, “COMBINATION PRODUCT” means a LICENSED PRODUCT sold in combination with another product that is not a LICENSED PRODUCT.

In any given year, royalties paid to the ROTHAMSTED as Sales Royalties or Sublicensing Royalties will be fully deductible against minimum annual royalties paid in the same year, but there shall be no carry forward.

Milestone Payments: A one-time milestone payment of [***] for the first regulatory filing for commercial production of a LICENSED PRODUCT in any country. A one-time milestone payment of [***] on obtaining the first regulatory approval for a LICENSED PRODUCT in any country for the commercial production of a LICENSED PRODUCT. A milestone payment of [***] on achieving cumulative net sales of LICENSED PRODUCTS of [***]. For clarity, each milestone will be paid only paid once.
