NOW, THEREFORE, in consideration of the mutual covenants and agreements hereinafter set forth and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, Cellectis and Calyxt hereby agree as follows:

1. INDEMNIFICATION

Calyxt shall indemnify Cellectis and keep Cellectis fully and effectively indemnified from and against and hold Cellectis harmless from and against any and all past, present and future payments, obligations, liabilities, losses, damages, penalties, judgments, actions, proceedings, claims, demands, costs, fees and expenses of any kind or nature whatsoever to which Cellectis may become subject or that may be imposed on, paid or incurred by, suffered by, made against or asserted against Cellectis, in any manner relating to, arising out of or in connection with the Lease Guaranty and/or any failure by Calyxt to perform any obligation under the Lease Agreement, or any claim, litigation, investigation or proceeding relating thereto and to reimburse Cellectis upon demand for any legal or other expenses incurred in connection with investigating, defending or enforcing any of the foregoing.

2. WAIVERS

2.1 Calyxt hereby waives, consistent with and to the extent waived in the Lease Guaranty, any and all defenses, legal or equitable, that it may have against any person to liability hereunder, including (i) the illegality, invalidity or unenforceability of the Lease Guaranty and (ii) all defenses that at any time may be available to it by virtue of any valuation, stay, moratorium or other law in effect on the Execution Date or thereafter in effect.

2.2 Calyxt hereby waives any setoff or counterclaim related to its obligations under this Agreement that may at any time be available to it.

2.3 Calyxt hereby waives presentment, demand for payment or performance, including diligence in making demands hereunder, notice of dishonor or nonperformance, protest and all other notices of any kind, including (i) notice of the existence, creation or incurrence of new or additional liabilities or obligations under the Lease Guaranty, (ii) notice of any action taken or omitted in connection with the Lease Guaranty, (iii) notice of any default by Cellectis, (iv) notice that any portion of the indebtedness, liabilities or obligations under the Lease Guaranty is due, and (v) notice of any action against Cellectis.

3. FURTHER ASSURANCES

3.1 Each of Cellectis and Calyxt hereby represents and warrants to the other Party that (a) the execution, delivery and performance by such Party of this Agreement are within such Party’s corporate powers and have been duly authorized by all necessary corporate action on the part of such Party and (b) this Agreement constitutes a valid and binding agreement of such Party enforceable against such Party in accordance with its terms (subject to applicable bankruptcy, insolvency, fraudulent transfer, reorganization, moratorium and other laws affecting creditors’ rights generally and general principles of equity).

3.2 Calyxt, at its own expense, shall perform promptly such acts as may be reasonably necessary or advisable, or that Cellectis may reasonably request at any time, to carry out the intent of this Agreement, including, to execute and deliver (or cause any third party to execute and deliver) any such additional agreements, documents and instruments to evidence Calyxt’s agreements to comply with the provisions of the Lease Guaranty and to indemnify Cellectis as set forth herein.

4. TERM

This Agreement shall become a valid and binding agreement of the Parties as of the execution by both Parties as set out in Article 8; notwithstanding the foregoing, Article 1 hereof shall not become effective and operative until such time as Cellectis and its Affiliates beneficially own, in the aggregate, a number of Calyxt Shares equal to 50% or less of the then-outstanding Calyxt Shares.

This Agreement shall remain in full force and effect until the termination of the Lease Guaranty pursuant to Section 12 of the Lease Guaranty or otherwise, unless earlier terminated by mutual written agreement of the Parties. Notwithstanding anything in this Agreement to the contrary, Article 1, as well as this second sentence of this second paragraph of Article 4, shall survive any expiration or termination of this Agreement, unless mutually agreed in writing by the Parties.

5. ENTIRE AGREEMENT

This Agreement represents the entire agreement between the Parties in relation to the subject matter of this Agreement and supersedes any previous agreement whether written or oral between the Parties in relation to that subject matter.

6. SEVERABILITY

If any term, provision, covenant or restriction of this Agreement is held by a court of competent jurisdiction or other governmental authority to be invalid, void or unenforceable, the remainder of the terms, provisions, covenants and restrictions of this Agreement shall remain in full force and effect and shall in no way be affected, impaired or invalidated so long as the economic or legal substance of the transactions contemplated hereby is not affected in any manner materially adverse to either Party. Upon such a determination, the Parties shall negotiate in good faith to modify this Agreement so as to affect the original intent of the Parties as closely as possible in an acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible.
