Section 15. Notices; Indemnity.

15.1 Notices. All notices, requests, consents and other communications hereunder shall be in writing, shall be addressed to the receiving party’s address set forth on the signature page hereto or to such other address as a party may designate by notice hereunder, and shall be either (a) delivered by hand, (b) sent by overnight courier, or

(c) sent by certified mail, return receipt requested, postage prepaid. All notices, requests, consents and other communications hereunder shall be deemed to have been given either (i) if by hand, at the time of the delivery thereof to the receiving party at the address of such party set forth above, (ii) if sent by overnight courier, on the next business day following the day such notice is delivered to the courier service, or (iii) if sent by certified mail, on the fifth business day following the day such mailing is made.

15.2 Indemnification. Subject to Section 9, each party shall indemnify the other party against any loss, cost or damages (including reasonable attorney’s fees and expenses) incurred as a result of such party’s breach of any representation, warranty, covenant or agreement set forth in this Agreement.

Section 16. Counterparts.

This Agreement may be executed in one or more counterparts, all of which when taken together shall be considered one and the same agreement and shall become effective when counterparts have been signed by each party and delivered to the other party, it being understood that both parties need not sign the same counterpart. In the event that any signature is delivered by facsimile transmission or any other form of electronic delivery, such signature shall create a valid and binding obligation of the party executing (or on whose behalf such signature is executed) with the same force and effect as if such signature page were an original thereof.

Section 17. Survival; Severability.

17.1 Survival. The representations, warranties, covenants and agreements of the parties hereto shall survive the Closing until one (1) year following the consummation of an initial Business Combination.

17.2 Severability. In the event that any provision of this Agreement becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable or void, this Agreement shall continue in full force and effect without said provision; provided that no such severability shall be effective if it materially changes the economic benefit of this Agreement to any party.

Section 18. Headings.

The titles and subtitles used in this Agreement are used for convenience only and are not to be considered in construing or interpreting this Agreement.

Section 19. Construction.

The parties hereto have participated jointly in the negotiation and drafting of this Agreement. If an ambiguity or question of intent or interpretation arises, this Agreement will be construed as if drafted jointly by the parties hereto and no presumption or burden of proof will arise favoring or disfavoring any party hereto because of the authorship of any provision of this Agreement. The words “include,” “includes,” and “including” will be deemed to be followed by “without limitation.” Pronouns in masculine, feminine, and neuter genders will be construed to include any other gender, and words in the singular form will be construed to include the plural and vice versa, unless the context otherwise requires. The words “this Agreement,” “herein,” “hereof,” “hereby,” “hereunder,” and words of similar import refer to this Agreement as a whole and not to any particular subdivision unless expressly so limited. The parties hereto intend that each representation, warranty, and covenant contained herein will have independent significance. If any party hereto has breached any representation, warranty, or covenant contained herein in any respect, the fact that there exists another representation, warranty or covenant relating to the same subject matter (regardless of the relative levels of specificity) which such party hereto has not breached will not detract from or mitigate the fact that such party hereto is in breach of the first representation, warranty, or covenant.

Section 20. Most Favored Nation.

The Company shall not enter into, with any investor of the Company (or any instruments entitling any investor to receive equity interests of the Company) an agreement which grants such investor any rights or benefits which are more favorable (including, without limitation, with respect to the commercial entitlements and price of equity interests of the Company under such offering) than the rights and benefits established in favor of each Purchaser under this Agreement, unless, in any such case, each Purchaser has also been provided such rights and benefits pursuant to a written agreement between each Purchaser and the Company. Notwithstanding the foregoing, this provision does not apply to any securities of the Company or the Sponsor that an investor may receive in exchange for a formal forward purchase agreement in connection with a private investment in public equity in support of the Company’s potential Business Combination and does not apply to securities issued to or purchased by the managing members of the Sponsor or the officers, directors and advisors of the Company.
