Sponsor Promote and Independent Director Shares (20% of Shares Outstanding) Sponsor and SPAC Investors Management Team

Unit (1 Common Share + 1 Warrant) Warrants USD Price (or Cash to fund Equivalent in Offering MXN) Expenses and SPAC Working Capital

Escrow Account Operating Account Funds in USD Working Capital

 SPAC raises capital by selling Units (1 Common Share + 1 Warrant) to local and international investors.

 Capital raised is held in a USD-denominated escrow account and invested in short-term government securities.

 The SPAC has 24 months to complete a business combination (unless the SPAC stockholders elect to extend the time frame), but if one does not occur, then the SPAC will liquidate and return each shareholder their pro rata amount in the escrow account net of certain expenses.

 Upon announcement of a business combination, shareholders will have time to evaluate the transaction. After evaluating, investors may sell in the open market, buy more shares in the open market, or receive reimbursement for their shares at the closing of the business combination for their pro rata amount in the escrow account.

25 SPAC Business Combination Process

 A publicly listed SPAC is an acquisition vehicle whereby a sponsor team raises a blind pool of cash in an IPO to acquire a private operating business or asset, or, in certain instances, a public company seeking to de‐lever, through a reverse merger

 Once the blind pool is raised in the initial IPO, the sponsor team has 24 months to identify an acquisition target that must be approved by a majority of SPAC shareholders (unless the SPAC stockholders elect to extend the time frame), at which point the SPAC merges with the target in a reverse merger and the acquisition target (if not already a public company) becomes a public operating company

1 IPO 4 Typical Shareholder Vote Process

 100% of IPO gross proceeds held in escrow account until acquisition completed 5 Acquisition NOT approved 5 Acquisition IS approved  Cash‐in‐escrow invested in short‐term government securities such as US Treasuries  Proposed transaction rejected if we do not  Simple majority of public investors in receive approval from a simple majority of the listed SPAC vote “yes” SPAC public investors

2 Acquisition announced SPAC may look for another target, time  Management puts out an announcement of permitting, proposed acquisition otherwise it faces liquidation  Company and seller prepare proxy materials for shareholder and regulatory approval

6 Escrow liquidation 6 Acquisition completed

3 Deal roadshow  Escrow liquidated and all funds returned  Target business or asset becomes a to public shareholders pro rata public operating company  Management team and the seller meet investors to discuss investment case  Sponsor does not have right to liquidation  No shareholder is forced to be proceeds over funds held in the escrow dragged along and each shareholder  Deal is marketed to current shareholders, account has the right to have their shares new investors and sector specialists reimbursed and canceled for a pro rata portion of cash‐in‐escrow
