c.Enforceability. The MOA has been duly executed and delivered by Seller and constitutes a legal, valid and binding obligation of Seller, enforceable against Seller in accordance with its terms, except as limited by bankruptcy, insolvency or other laws of general application relating to or affecting the enforcement of creditors’ rights generally and general principles of equity.

d.Non-Contravention. Seller’s execution and delivery of the MOA and the performance and consummation of the transactions contemplated hereby do not and will not (i) violate the certificate of incorporation and bylaws or other governing documents of Seller (collectively, the “Organizational Documents”) or any material judgment, order, writ, decree, statute, rule or regulation applicable to Seller; (ii) violate any provision of, or result in the breach or the acceleration of, or entitle any other person to accelerate (whether after the giving of notice or lapse of time or both), any material mortgage, indenture, agreement, instrument or contract to which such Seller is a party or by which it is bound; or (iii) result in the creation or imposition of any lien upon any property, asset or revenue of Seller or the suspension, revocation, impairment, forfeiture, or nonrenewal of any material permit, license, authorization or approval applicable to Seller, its business or operations (including the business and operations of its wholly owned subsidiaries), or any of its assets or properties, except as would not reasonably be expected to (x) have a material and adverse effect on the Seller or (y) prevent, delay or otherwise impair Seller’s ability to perform its obligations under this MOA, the Contracts or any other agreement entered into by the Parties after the date hereof.

e.Approvals. No consent, approval, order or authorization of, or registration, declaration or filing with, any governmental authority or other person is required in connection with the execution and delivery of this MOA by Seller and the performance and consummation of the transactions contemplated hereby, other than such as have been obtained and remain in full force and effect and other than such qualifications or filings under applicable securities laws as may be required in connection with the transactions contemplated by this Agreement.

13.Complete Agreement. This MOA constitutes the complete and exclusive agreement between the Parties with respect to the Advances and supersedes all previous agreements between the Parties relating thereto, whether written or oral.

Boeing and Seller hereby irrevocably consent to and submit themselves exclusively to the jurisdiction of the applicable courts of King County, Washington, and the federal courts of Washington State for the purpose of any suit, action, or other judicial proceeding arising out of or connected with this MOA.

Notwithstanding the above, the Parties may file this MOA with the SEC, if legally required to do so, but must give the other Party two business days advance written notice and will omit confidential information as permitted by applicable law as appropriate after providing such Party the opportunity to provide comments. Nothing in this section will prevent either Party from making reasonable disclosures concerning this MOA during the course of its earnings calls.

18.Interpretation. Each Party has had the opportunity to draft, review, and edit this MOA. Accordingly, no presumption for or against either Party arising out of drafting all or any part of this MOA will be applied in any action relating to or arising from this MOA; and the Parties hereby waive the benefit of any statute or common law rule providing that in cases of uncertainty language of a contract should be interpreted against the Party who caused the uncertainty to exist.

EXECUTED as of the Effective Date by the duly authorized representatives of the Parties.
