SECTION 13.03. Remedies. Each Party acknowledges that any unauthorized use or disclosure of Confidential Information, or any threat
thereof, would cause the Disclosing Party irreparable harm that could not be fully remedied by monetary damages. Accordingly, in the event of a breach or threatened breach by a Party of the confidentiality obligations set forth herein, the other
Party shall have the right, in addition to, and not in lieu of, monetary damages or any other legal or equitable remedy available to it, to seek injunctive or other equitable relief from a court of competent jurisdiction, without the necessity of
proving damages or posting any bond, as may be necessary to prevent unauthorized use or disclosure of Confidential Information.

 SECTION 14.04. Publicity. 

(a) Neither Party shall (either directly or indirectly), and neither Party shall permit any of its Affiliates to, issue or make any public
release or announcement with respect to or concerning any matter the subject of, or contemplated by, this Agreement without reasonable prior consultation with the other Party and affording such other Party a reasonable opportunity to provide
comments on such proposed release or announcement; provided, however, that, subject to the provisions of Section 14.04(b), nothing in this Agreement shall prevent either Party from independently making such public disclosure or filing as
it determines in good faith is required by Applicable Law. 
 (b) In the event that a Party determines in good faith that disclosure or

all Confidential Information or other information of a competitively sensitive nature, (ii) allow the other Party reasonable time to review such redactions and (iii) make such further redactions as are reasonably proposed by the reviewing

Affiliates or subcontractors in connection with the performance of its obligations under this Agreement. [***]. Any attempted assignment or delegation in violation of this Section 14.05 shall be null and void and shall be ineffective to relieve
either Party of its obligations hereunder.

Party for any consequential damages (including lost profits, business, revenue, goodwill or anticipated savings and loss of or damage to data and records), special damages, incidental damages, indirect damages or punitive damages under this
Agreement, even if advised that any of these types of damages may occur. 
 SECTION 14.07. Further Assurances. Each Party shall take
all actions reasonably necessary to give effect to this Agreement and comply with any Applicable Laws in respect of its obligations hereunder. 

SECTION 14.08. Severability. In the event that any provision of this Agreement shall be held to be invalid or unenforceable, the same
shall not affect in any respect whatsoever the validity or enforceability of the remainder of this Agreement. If a provision hereof is held to be invalid or unenforceable, the Parties shall negotiate in good faith to replace the invalid or
unenforceable provision to the greatest extent possible with another valid provision that will achieve the same economic effect intended by the provision held invalid or unenforceable in the context of this Agreement.

Existing Purchase Order, the Letter Agreement and any Purchase Order set forth the entire agreement and understanding between the Parties as to the subject matter hereof and thereof and supersede all prior agreements, oral or written, and all other
prior communications between the Parties relating to the subject matter hereof and thereof; provided that nothing herein shall alter the terms of the Investment.

shall be fairly interpreted in accordance with its terms and without any strict construction in favor of or against either Party. 
 SECTION
14.13. Waiver of Trial by Jury. Each Party hereby waives, and agrees to cause each of its respective Affiliates to waive, to the fullest extent permitted by Applicable Law, any right it may have to a trial by jury in respect of any litigation
directly or indirectly arising out of or in connection with this Agreement. Each Party (a) certifies that no Representative of the other Party has represented, expressly or otherwise, that such other Party would not, in the event of litigation,
seek to enforce the foregoing waiver and (b) acknowledges that it and the other Party have been induced to enter into this Agreement by, among other things, the mutual waivers and certifications in this Section 14.13.

 SECTION 14.15. Amendments; Waiver. Amendments to this Agreement may be made from time
to time; provided, however, that no amendment or modification of this Agreement or any provision hereof shall be valid or effective unless in writing and signed by each Party. No consent to, or waiver, discharge or release of, any provision
of or breach under this Agreement shall be valid or effective unless in writing and signed by the Party giving such waiver, and no specific waiver shall constitute a waiver with respect to any other provision or breach, whether or not of similar
nature. Failure on the part of any Party to insist in any instance upon strict, complete and timely performance by the other Party of any provision of or obligation under this Agreement shall not constitute a waiver by such Party of any of its
rights under this Agreement or otherwise. 
 SECTION 14.16. Successors and Assigns. This Agreement shall be binding upon and inure to
the benefit of the respective successors and permitted assigns of each Party; provided, however, that no Party may transfer or assign any of such Party’s rights, interests or obligations hereunder, except in accordance with the terms of

a Party set forth herein are not exclusive, but rather are in addition to those rights and remedies that may be available to a Party at law or in equity. 

SECTION 14.19. Third Party Beneficiaries. This Agreement is intended only for the Parties’ benefit, and nothing in this Agreement
may be construed to create any duty to, any standard of care concerning, or any liability to, any person not a Party to this Agreement, other than (a) an applicable Project Company or (b) an Indemnified Party’s rights to
indemnification pursuant to Section 14.03.
