Purpose of Transaction

Founder Shares

On March 26, 2021, the Sponsor, along with certain of the Issuer’s directors and officers, and A.G.P./Alliance Global Partners, the representative of the underwriters in the Issuer’s initial public offering (“A.G.P.”) purchased an aggregate of 4,312,500 shares of Common Stock for an aggregate purchase price of $25,000, of which 2,551,919 shares were purchased by DC Rainier SPV LLC.

Concurrently with the closing of the Issuer’s initial public offering on October 7, 2021 (the “IPO”), the underwriters exercised the over-allotment option in full and the additional 50,000 shares of Common Stock were transferred to the Sponsor, resulting in an aggregate of 2,951,919 founder shares of Common Stock held by the Sponsor.

Private Placement Units

On October 7, 2021, simultaneously with the closing of the Issuer’s IPO, the Sponsor acquired 583,200 private placement units (“Private Placement Units”) at $10.00 per Private Placement Unit, for an aggregate purchase price of $5,832,000, pursuant to a Private Placement Unit Subscription Agreement dated October 4, 2021 between the Issuer, the Sponsor, the Chief Executive Officer of the Issuer and the Chief Financial Officer of the Issuer (the “Private Placement Unit Subscription Agreement”).

On October 4, 2021, the Issuer entered into a letter agreement (the “Letter Agreement”) with the Sponsor, the Issuer’s officers and directors, and A.G.P. Pursuant to the Letter Agreement, the Sponsor, the Issuer’s officers and directors and A.G.P. have each agreed that if the Issuer seeks shareholder approval of a proposed business combination it will vote all shares held by it in favor of such proposed business combination.

Pursuant to the Letter Agreement, the Sponsor has agreed not to transfer any founder shares (or shares of Common Stock issuable upon conversion thereof) until the earliest of (A) one year after the completion of the Issuer’s initial business combination and (B) subsequent to the Issuer’s initial business combination, (x) if the last reported sale price of the Common Stock equals or exceeds $12.00 per share (as adjusted for stock splits, stock dividends, reorganizations, recapitalizations and the like) for any 20 trading days within any 30-trading day period commencing at least 150 days after the Issuer’s initial business combination or (y) the date on which the Issuer completes a liquidation, merger, capital stock exchange, reorganization or other similar transaction that results in all of the Issuer’s stockholders having the right to exchange their shares of Common Stock for cash, securities or other property.

The Letter Agreement provides exceptions pursuant to which the Sponsor can transfer such shares to certain permitted transferees as further described in the Letter Agreement. Under the Letter Agreement, neither the Private Placement Units nor the securities underlying such units may be transferred (except to certain permitted transferees) until 30 days after the consummation of the initial business combination.

Under the Letter Agreement, the Sponsor also agreed it will not propose any amendment to the Issuer’s Amended and Restated Certificate of Incorporation that would affect the substance or timing of the Issuer’s obligation to redeem the shares of Common Stock underlying the units sold in the Issuer’s IPO if the Issuer does not complete a business combination within 15 months from the closing of its IPO unless the Issuer provides its public shareholders with the opportunity to redeem their shares upon approval of any such amendment.

Under the Letter Agreement, the Sponsor agreed to waive, with respect to any shares of the Common Stock held by it, any redemption rights it may have in connection with the consummation of a business transaction, including, without limitation, any such rights available in the context of a shareholder vote to approve such business transaction or in the context of a tender offer made by the Issuer to purchase shares of the Common Stock.

The Sponsor also agreed that in the event of the liquidation of the Trust Account of the Issuer (as defined in the Letter Agreement), it will indemnify and hold harmless the Issuer against any and all loss, liability, claims, damage and expense whatsoever which the Issuer may become subject as a result of any claim by any third party for services rendered or products sold to the Issuer, or by any prospective target business with which the Issuer has entered into a letter of intent, confidentiality or other similar agreement for a business combination, but only to the extent necessary to ensure that such loss, liability, claim, damage or expense does not reduce the amount of funds in the Trust Account to below (i) $10.20 per public share or (ii) such lesser amount per public share held in the trust account as of the date of the liquidation of the trust account, due to reductions in value of the trust assets, in each case net of the amount of interest which may be withdrawn to pay taxes; provided that such indemnity shall not apply if such third party or prospective target business executes an agreement waiving any claims against the Trust Account.

The description of the Letter Agreement is qualified in its entirety by reference to the full text of such agreement, a copy of which is filed as an exhibit hereto.

Stock Escrow Agreement

On October 4, 2021, the Issuer entered into a stock escrow agreement (the “Stock Escrow Agreement”), with American Stock Transfer & Trust Company, LLC, as escrow agent, and the initial stockholders, including the Sponsor.

The summary of such Warrant Agreement contained herein is qualified in its entirety by reference to the full text of such agreement, a copy of which is filed as an exhibit hereto.
