(c)            The Investor (i) is a “qualified institutional buyer” (as defined in Rule 144A under the Securities Act), an institutional “accredited investor” (within the meaning of Rule 501(a)(1), (2), (3) or (7) under the Securities Act) or an “accredited investor” (within the meaning of Rule 501(a)(4), (5), (6) or (7)), in each case, satisfying the applicable requirements set forth on Annex A, (ii) is acquiring any New Investor Shares that may be issued to the Investor pursuant to this Agreement only for its own account and not for the account of others, or if the Investor is acquiring any New Investor Shares that may be issued to the Investor pursuant to this Agreement as a fiduciary or agent for one or more investor accounts, each owner of such account is a qualified institutional buyer, institutional accredited investor or accredited investor (as the case may be) and the Investor has full investment discretion with respect to each such account, and the full power and authority to make the acknowledgements, representations and agreements herein on behalf of each owner of each such account, and (iii) is not acquiring any New Investor Shares that may be issued to the Investor pursuant to this Agreement with a view to, or for offer or sale in connection with, any distribution thereof in violation of the Securities Act.

The Investor understands that the New Investor Shares may not be offered, resold, transferred, pledged or otherwise disposed of by the Investor except (i) pursuant to an effective registration statement under the Securities Act, (ii) to the extent the Investor has delivered to Vast (if requested by Vast) an opinion of counsel, in a form reasonably acceptable to Vast, to the effect that such New Investor Shares to be sold, assigned or transferred may be sold, assigned or transferred pursuant to an exemption from such registration, (iii) pursuant to Rule 144 promulgated under the Securities Act (or a successor rule thereto) provided that all of the applicable conditions thereof have been met or (iv) otherwise pursuant to an applicable exemption from the registration requirements of the Securities Act, and in accordance with any applicable securities laws of the applicable states and other jurisdictions of the United States, and that any certificates or book-entry records representing the New Investor Shares shall contain a restrictive legend to such effect. The Investor acknowledges that the New Investor Shares will not be eligible for resale pursuant to Rule 144A under the Securities Act. The Investor acknowledges and agrees that the New Investor Shares will be subject to these securities law transfer restrictions and, as a result of these transfer restrictions, the Investor may not be able to readily resell the New Investor Shares and may be required to bear the financial risk of an investment in the New Investor Shares for an indefinite period of time. The Investor understands that it has been advised to consult legal counsel prior to making any offer, resale, pledge or transfer of any of the New Investor Shares. Notwithstanding the foregoing, the New Investor Shares may be pledged in connection with a bona fide margin account or other loan or financing arrangement secured by the New Investor Shares and such pledge of New Investor Shares shall not be deemed to be a transfer, sale or assignment of the New Investor Shares hereunder, and the Investor, by effecting a pledge of New Investor Shares, shall not be required to provide Vast with any notice thereof or otherwise make any delivery to Vast pursuant to this Agreement.

(e)            In making its decision to invest in the New Investor Shares, the Investor has relied solely upon independent investigation made by the Investor and Vast’s and SPAC’s representations, warranties and covenants contained herein.

The Investor acknowledges and agrees that the Investor has received such information as the Investor deems necessary in order to make an investment decision with respect to the New Investor Shares, including with respect to Vast, SPAC and the Business Combination, and made its own assessment and is satisfied concerning the relevant tax and other economic considerations relevant to the Investor’s investment in the New Investor Shares. The Investor represents and agrees that the Investor and the Investor’s professional advisor(s), if any, have had the full opportunity to ask such questions, receive such answers and obtain such information as the Investor and its professional advisor(s), if any, have deemed necessary to make an investment decision with respect to the New Investor Shares. Without limiting the generality of the foregoing, the Investor acknowledges that it has had an opportunity to review the SEC Reports.

(f)            Investor became aware of the offering of the New Investor Shares solely by means of direct contact between the Investor, Vast, SPAC or their representatives or affiliates. The Investor did not become aware of the offering of the New Investor Shares, nor were the New Investor Shares offered to the Investor, by any other means. The Investor acknowledges that New Investor Shares (i) were not offered by any form of general solicitation or general advertising and (ii) are not being offered in a manner involving a public offering under the Securities Act or any state securities laws.

(g)            Investor acknowledges that it is aware that there are substantial risks incident to the ownership of the New Investor Shares. The Investor has such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the New Investor Shares, and the Investor has had an opportunity to seek, and has sought, such accounting, legal, business and tax advice as the Investor has considered necessary to make an informed investment decision. The Investor is not relying on any statements or representations of Vast, SPAC or any of its agents for legal, tax or investment advice with respect to this Agreement or the transactions contemplated by the Agreement.

(h)            The Investor has fully considered the risks of an investment in the New Investor Shares and determined that the New Investor Shares are a suitable investment for the Investor and that the Investor is able at this time and in the foreseeable future to bear the economic risk of a total loss of the Investor’s investment in the New Investor Shares. The Investor acknowledges specifically that a possibility of total loss exists.

(i)            The Investor understands and agrees that no federal or state agency has passed upon or endorsed the merits of the offering of the New Investor Shares or made any findings or determination as to the fairness of this investment.

(j)            No broker or finder has acted on behalf of the Investor in such a way as to create any liability on Vast or SPAC in connection with this Agreement.

(k)            The Investor is not entering into the transactions contemplated by this Agreement to create actual or apparent trading activity in the SPAC Class A Shares (or any security convertible into or exchangeable for SPAC Class A Shares) or to raise or depress or otherwise manipulate the price of the SPAC Class A Shares (or any security convertible into or exchangeable for the SPAC Class A Shares) or otherwise in violation of the Exchange Act.

(l)            The Investor is not (i) a person or entity named on the List of Specially Designated Nationals and Blocked Persons, the Executive Order 13599 List, the Foreign Sanctions Evaders List, or the Sectoral Sanctions Identification List, each of which is administered by the U.S. Treasury Department’s Office of Foreign Assets Control (“OFAC”) (collectively “OFAC Lists”), (ii) owned or controlled by, or acting on behalf of, a person, that is named on an OFAC List, (iii) organized, incorporated, established, located, resident or born in, or a citizen, national, or the government, including any political subdivision, agency, or instrumentality thereof, of, Cuba, Iran, North Korea, Sudan, Syria, the Crimea region of Ukraine, or any other country or territory embargoed or subject to substantial trade restrictions by the United States, (iv) a Designated National as defined in the Cuban Assets Control Regulations, 31 C.F.R.

The Investor also represents that, to the extent required, it maintains policies and procedures reasonably designed to ensure compliance with OFAC-administered sanctions programs, including screening its investors against the OFAC Lists.
