PRIVATE PLACEMENT WARRANT PURCHASE AGREEMENT

This PRIVATE PLACEMENT WARRANT PURCHASE AGREEMENT (this “Agreement”) is made as of _________, 2024, by and among GigCapital7 Corp., a Cayman Islands exempted company (the “Company”), and GigAcquisitions7 Corp., a Cayman Islands exempted company (“Purchaser”).

WHEREAS, the Company was formed for the purpose of effecting a merger, capital share exchange, asset acquisition, share purchase, reorganization or similar business combination with one or more businesses (the “Business Combination”).

WHEREAS, the Company intends to consummate an initial public offering of the Company’s units (the “IPO”), each unit consisting of one Class A Ordinary Share, par value $0.0001 per share, of the Company (an “Ordinary Share”), and one redeemable warrant, as described in that certain Registration Statement on Form S-1 (file No. 333-280015), initially filed with the Securities and Exchange Commission on June 7, 2024 (“Registration Statement”).

WHEREAS, each whole warrant entitles the holder to purchase one Ordinary Share at an exercise price of $11.50 per Ordinary Share.

WHEREAS, the Purchaser has agreed to purchase an aggregate of 3,719,000 warrants (the “Private Placement Warrants”), each Private Placement Warrant entitling the holder to purchase one Ordinary Share at an exercise price of $11.50 per share.

NOW THEREFORE, in consideration of the mutual promises contained in this Agreement and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties to this Agreement hereby, intending legally to be bound, agree as follows:

1. Authorization, Purchase and Sale; Terms of the Private Placement Warrants.

1.1. Authorization of the Private Placement Warrants. The Company has duly authorized the issuance and sale of the Private Placement Warrants to the Purchaser.

1.2. Purchase and Sale of the Private Placement Warrants. On the date of the consummation of the IPO or on such earlier time and date as may be mutually agreed by the Purchaser and the Company (the “Closing Date”), the Company shall issue and sell to the Purchaser, and the Purchaser shall purchase from the Company, an aggregate of 3,719,000 Private Placement Warrants at a price of $.01561 per warrant for an aggregate purchase price of $58,060 (the “Purchase Price”), which shall be paid by wire transfer of immediately available funds to the Company at least one business day prior to the Closing Date in accordance with the Company’s wiring instructions. On the Closing Date, upon the payment by the Purchaser of the Purchase Price, the Company, at its option, shall deliver a certificate evidencing the Private Placement Warrants purchased by the Purchaser on such date duly registered in the Purchaser’s name to the Purchaser, or effect such delivery in book-entry form.

1.3. Terms of the Private Placement Warrants.

(a) Each Private Placement Warrant shall have the terms set forth in a Warrant Agreement to be entered into by the Company and a warrant agent in connection with the IPO (a “Warrant Agreement”).

(b) At the time of the closing of the IPO, the Company and the Purchaser shall enter into a registration rights agreement (the “Registration Rights Agreement”) pursuant to which the Company will grant certain registration rights to the Purchaser relating to the Private Placement Warrants and the Ordinary Shares underlying the Private Placement Warrants (collectively, the “Securities”).

1.4. Conditions to Closing. The obligation of Purchaser to purchase and pay for the Private Placement Warrants as provided herein shall be contingent upon, and concurrent with, the consummation of the IPO.

1.5. Termination. This Agreement and each of the obligations of the undersigned shall be null and void and without effect if a Closing does not occur prior to December 31, 2024, or if that certain Underwriting Agreement, dated as of the date hereof, by and among the Company, Craft Capital Management LLC as representative of the underwriters named therein (the “Underwriting Agreement”), is terminated for any reason.

2. Representations and Warranties of the Purchaser.

Purchaser represents and warrants to the Company that:

2.1. No Government Recommendation or Approval. Purchaser understands that no federal or state agency has passed upon or made any recommendation or endorsement of the Company or the sale of the Private Placement Warrants.

2.2. Accredited Investor. Purchaser represents that it is an “accredited investor” as such term is defined in Rule 501(a) of Regulation D under the Securities Act of 1933, as amended (the “Securities Act”), and acknowledges that the sale contemplated hereby is being made in reliance, among other things, on a private placement exemption to “accredited investors” under the Securities Act and similar exemptions under state law.

2.3. Intent. Purchaser is purchasing the Securities solely for investment purposes, for Purchaser’s own account (and/or for the account or benefit of its members or affiliates, as permitted, pursuant to the terms hereof), and not with a view to the distribution thereof and Purchaser has no present arrangement to sell the Securities to or through any person or entity except as may be permitted hereunder. Purchaser shall not engage in hedging transactions with regard to the Securities unless in compliance with the Securities Act.

2.4. Restrictions on Transfer. Purchaser acknowledges and understands the Private Placement Warrants are being offered in a transaction not involving a public offering in the United States within the meaning of the Securities Act. The Securities have not been registered under the Securities Act and, if in the future Purchaser decides to offer, resell, pledge or otherwise transfer the Securities, such Securities may be offered, resold, pledged or otherwise transferred only (i) pursuant to an effective registration statement filed under the Securities Act, (ii) pursuant to an exemption from registration under Rule 144 promulgated under the Securities Act, if available, or (iii) pursuant to any other available exemption from the registration requirements of the Securities Act, and in each case in accordance with any applicable securities laws of any state or any other jurisdiction. Notwithstanding the foregoing, Purchaser acknowledges and understands the Securities are subject to transfer restrictions as described in Section 6 hereof. Purchaser agrees that if any transfer of its Securities or any interest therein is proposed to be made, as a condition precedent to any such transfer, Purchaser may be required to deliver to the Company an opinion of counsel satisfactory to the Company with respect to such transfer. Absent registration or another available exemption from registration, Purchaser agrees it will not resell the Securities (unless otherwise permitted pursuant to the terms hereof). Purchaser further acknowledges that because the Company is a shell company, Rule 144 may not be available to Purchaser for the resale of the Securities until the one-year anniversary following consummation of the Business Combination of the Company, despite technical compliance with the requirements of Rule 144 and the release or waiver of any contractual transfer restrictions.

2.5. Sophisticated Investor.

(a) Purchaser is sophisticated in financial matters and is able to evaluate the risks and benefits of the investment in the Securities.

(b) Purchaser is aware that an investment in the Securities is highly speculative and subject to substantial risks because, among other things, (i) the Securities are subject to transfer restrictions and have not been registered under the Securities Act and therefore cannot be sold unless subsequently registered under the Securities Act or an exemption from such registration is available and (ii) Purchaser has waived its redemption rights with respect to the Securities as set forth in Section 5 hereof, and the Securities held by Purchaser are not entitled to, and have no right, interest or claim to any monies held in the Trust Account, and accordingly Purchaser may suffer a loss of a portion or all of its investment in the Securities. Purchaser is able to bear the economic risk of its investment in the Securities for an indefinite period of time.

2.6. Organization and Authority. Purchaser is duly organized, validly existing and in good standing under the laws of its state of incorporation or formation and it possesses all requisite power and authority necessary to carry out the transactions contemplated by this Agreement.

2.7. Authority. This Agreement has been validly authorized, executed and delivered by Purchaser and is a valid and binding agreement enforceable in accordance with its terms, subject to the general principles of equity and to bankruptcy or other laws affecting the enforcement of creditors’ rights generally.

2.8. No Conflicts. The execution, delivery and performance of this Agreement and the consummation by Purchaser of the transactions contemplated hereby do not violate, conflict with or constitute a default under (i) Purchaser’s charter documents, (ii) any agreement or instrument to which Purchaser is a party or (iii) any law, statute, rule or regulation to which Purchaser is subject, or any agreement, order, judgment or decree to which Purchaser is subject.

2.9. No Legal Advice from Company. Purchaser acknowledges it has had the opportunity to review this Agreement and the transactions contemplated by this Agreement and the other agreements entered into between the parties hereto with Purchaser’s own legal counsel and investment and tax advisors. Except for any statements or representations of the Company made in this Agreement and the other agreements entered into between the parties hereto, Purchaser is relying solely on such counsel and advisors and not on any statements or representations of the Company or any of its representatives or agents for legal, tax or investment advice with respect to this investment, the transactions contemplated by this Agreement or the securities laws of any jurisdiction.

2.10. Reliance on Representations and Warranties. Purchaser understands the Private Placement Warrants are being offered and sold to Purchaser in reliance on exemptions from the registration requirements under the Securities Act, and analogous provisions in the laws and regulations of various states, and that the Company is relying upon the truth and accuracy of the representations, warranties, agreements, acknowledgments and understandings of Purchaser set forth in this Agreement in order to determine the applicability of such provisions.

2.11. No General Solicitation. Purchaser is not subscribing for the Private Placement Warrants as a result of or subsequent to any general solicitation or general advertising, including but not limited to any advertisement, article, notice or other communication published in any newspaper, magazine, or similar media or broadcast over television or radio, or presented at any seminar or meeting or in the Registration Statement.

2.12. Legend. Purchaser acknowledges and agrees the book-entries evidencing each of the Securities shall bear a restrictive legend (the “Legend”), in form and substance substantially as set forth in Section 4 hereof.

3.5. No Conflicts. The execution, delivery and performance of this Agreement and the consummation by the Company of the transactions contemplated hereby do not (i) result in a violation of the Company’s certificate of incorporation or by-laws, (ii) conflict with, or constitute a default under any agreement or instrument to which the Company is a party or (iii) any law statute, rule or regulation to which the Company is subject or any agreement, order, judgment or decree to which the Company is subject.
