Except for the payment of deferred underwriting commissions and the withdrawal of interest to pay taxes, none of the funds held in the Trust Account (including the interest earned on the funds held in the Trust Account) will be released from the Trust Account until the earliest to occur of (i) the completion of the initial Business Combination, (ii) the redemption of 100% of the Offering Shares (as defined below) if the Corporation is unable to complete its initial Business Combination within 18 months from the closing of the Offering, provided that GigAcquisitions5, LLC may decide to extend the date by which it has to consummate a business combination up to six (6) times for an additional one (1) month each time (or up to 24 months from the closing date of the Offering), provided that GigAcquisitions5, LLC (or its designees) must deposit into the Trust Account for each one-month extension funds equal to $100,000 in exchange for a non-interest bearing, unsecured promissory note), and (iii) the redemption of shares in connection with a vote seeking to amend any provisions of the Amended and Restated Certificate relating to the Corporation’s pre-initial Business Combination activity and related stockholders’ rights (as described in Section 9.7). Holders of shares of Common Stock included as part of the units sold in the Offering (the “Offering Shares”) (whether such Offering Shares were purchased in the Offering or in the secondary market following the Offering and whether or not such holders are Founders (as such term is defined in the Registration Statement), officers or directors of the Corporation, or affiliates of any of the foregoing) are referred to herein as “Public Stockholders. The gross proceeds from the issuance of such promissory notes pursuant to subpart (ii) above of this Section 9.1(b) will be added to the proceeds from the Offering to be held in the Trust Account and shall be used in accordance with this Article IX to fund the redemption of the Offering Shares that have not been previously redeemed.”
