Exhibit 10.5

WAIVER AGREEMENT

This WAIVER AGREEMENT (this “Agreement”), dated as of February ____, 2021, is made by and among Six4 Holdings, LLC, a Delaware limited liability company (the “Sponsor”), the other holders of SPAC Class B Common Stock (as defined below) set forth on Schedule I hereto (the “Other Class B Holders”, and together with the Sponsor, collectively, the “Class B Holders”), NavSight Holdings, Inc., a Delaware corporation (“SPAC”) and Spire Global, Inc (the “Company”). Sponsor, Company and the Other Class B Holders, and SPAC shall be referred to herein collectively as the “Parties” and individually as a “Party”. Capitalized terms used but not otherwise defined herein shall have the meanings ascribed to such terms in the Business Combination Agreement (as defined below). Sponsor, the Class B Holders, and the Company are collectively referred to herein as the “Parties” and individually as a “Party.”

WHEREAS, SPAC, NavSight Merger Sub Inc., a Delaware corporation and wholly-owned subsidiary of SPAC (“Merger Sub”), the Company and certain other parties propose to enter into that certain Business Combination Agreement, dated as of the date hereof (as amended, restated, supplemented, or otherwise modified from time to time, the “Business Combination Agreement”), pursuant to which, among other things, Merger Sub will merge with and into the Company (the “Merger”), with the Company surviving as a wholly owned subsidiary of SPAC;

WHEREAS, the Class B Holders own shares of Class B common stock of SPAC (the “SPAC Class B Common Stock”); and

WHEREAS, the Business Combination Agreement contemplates that the Parties will enter into this Agreement concurrently with the entry into the Business Combination Agreement, pursuant to which the Class B Holders are waiving any adjustment to the conversion ratio set forth in the Certificate of Incorporation or any other anti-dilution or similar protection with respect to the shares of SPAC Class B Common Stock related to the transactions contemplated by the Business Combination Agreement, with the result that shares of SPAC Class B Common Stock will convert into shares of Class A common stock of SPAC (“SPAC Class A Common Stock”) on a 1-for-1 basis, subject to, and conditioned upon, the occurrence of the Closing and effective as of immediately prior to the Merger.

NOW, THEREFORE, in consideration of the premises and the mutual promises contained herein and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the Parties, each intending to be legally bound, hereby agree as follows:

1. Waiver of Anti-Dilution Protection. Subject to, and conditioned upon, the occurrence of the Closing, each of the Class B Holders, by this Agreement, hereby irrevocably waives (for such Class B Holder and for such Class B Holder’s successors, heirs and assigns), to the fullest extent of the law and the Certificate of Incorporation, and agrees not to assert or perfect, any rights to adjustment or other anti-dilution protections with respect to the rate at which the shares of SPAC Class B Common Stock held by such Class B Holder as of the date hereof or as of immediately prior to the consummation of the Business Combination Agreement convert into shares of SPAC Class A Common Stock in connection with the transactions contemplated by the Business Combination Agreement; provided that, for the avoidance of doubt, the shares of SPAC Class B Common Stock held by each such Class B Holder as of immediately prior to the consummation of the Business Combination Agreement shall convert to shares of SPAC Class A Common Stock on a 1-for-1 basis upon the consummation of the transactions contemplated by the Business Combination Agreement (subject to adjustment for any share split, reverse share split or similar equity restructuring transaction involving SPAC).

2. Termination. This Agreement shall terminate and shall be of no further force and effect if, and at such time, if any, as, the Business Combination Agreement is terminated in accordance with its terms prior to the Closing.

3. Waiver. Any Party may, at any time prior to the Closing, by action taken by its board of directors or equivalent governing body, or officers thereunto duly authorized, waive in writing any rights or conditions in its favor under this Agreement or agree to an amendment or modification to this Agreement in the manner contemplated by Section 10 and by an agreement in writing executed in the same manner (but not necessarily by the same Persons) as this Agreement.
