Business Combination Agreement

On June 26, 2024, Goldenstone Acquisition Limited (the "Registrant" or "Parent") entered into a Business Combination Agreement (the "Agreement") with Infintium Fuel Cell Systems, Inc., a Delaware corporation (the "Company"), Pacifica Acquisition Corp., a Delaware corporation ("Merger Sub") and wholly-owned subsidiary of the Registrant, and Yan (Chris) Feng, solely in his capacity as representative, agent and attorney-in-fact of the Company Securityholders (the "Securityholder Representative," and, together with the Company, the Registrant, Merger Sub, the "Parties"), pursuant to which Merger Sub will merge with and into the Company (the "Merger"), with the Company surviving the Merger as a wholly-owned subsidiary of Parent. In connection with the Merger, Parent will change its name to "Infintium Fuel Cell Systems Holdings, Inc." The board of directors of the Registrant has unanimously (i) approved and declared advisable the Agreement, the Merger and the other transactions contemplated by the Agreement and (ii) resolved to recommend approval of the Agreement and related matters by the stockholders of the Registrant once the Registration Statement has been declared effective. Capitalized terms used herein but not otherwise defined have the meanings set forth in the Agreement.

Treatment of Company Securities

Common Stock. At the effective time of the Merger (the "Effective Time"), each share of the Class A common stock, par value $0.0001 per share, of the Company ("Class A Common Stock"), and Class B common stock, par value $0.0001 per share, of the Company ("Class B Common Stock," and, together with the Class A Common Stock, the "Company Common Stock"), other than any shares the holders of which exercise dissenters' rights of appraisal, will be converted into the right to receive shares of the common stock of Parent, par value $0.0001 per share (the "Parent Common Stock"). The total number of shares of Parent Common Stock to be issued will be based on the valuation of the Company and will be calculated by dividing such valuation by $10.00. The valuation of the Company at the closing of the Merger ("Closing") will be $130,000,000, or such other amount as may be determined by a valuation firm in accordance with the terms of the Agreement. Parent has engaged a valuation firm to provide such a valuation.

Options. Each option of the Company (the "Company Option") that is outstanding immediately prior to the Effective Time will be converted into an option to purchase a number of shares of Parent Common Stock at an exercise price equal to the exercise price of such Company Option. The number of shares that may be purchased will be proportionately adjusted by the Exchange Ratio.

Earnout. Following the Closing, Company stockholders (but excluding the holders who exercise dissenters' rights) will be entitled to receive 500,000 Merger Consideration Earnout Shares in accordance with their respective Pro Rata Shares, if, within 12 months from the Closing Date, the closing share price of Parent Common Stock equals or exceeds $11.50 for any 20 consecutive Trading Days within such 12-month period. Company stockholders (but excluding the holders who exercise dissenters' rights) will be entitled to receive 500,000 Merger Consideration Earnout Shares in accordance with their respective Pro Rata Shares, if, within 24 months from the Closing Date, the closing share price of Parent Common Stock equals or exceeds $13.00 for any 20 consecutive Trading Days within such 24-month period. Further, Company stockholders (but excluding the holders who exercise dissenters' rights) will be entitled to receive 500,000 Merger Consideration Earnout Shares in accordance with their respective Pro Rata Shares, if, within 36 months from the Closing Date, the closing share price of Parent Common Stock equals or exceeds $15.00 for any 20 consecutive Trading Days within such 36-month period.
