The Platform and all investment opportunities offered through it are available exclusively to accredited investors as defined under Rule 501 of Regulation D of the Securities Act of 1933. To use this Platform and invest in the Fund, you must meet all of the following requirements:

• You must be an "accredited investor" as defined in Rule 501 of Regulation D, which includes individuals with a net worth exceeding $1 million (excluding primary residence), annual income exceeding $200,000 ($300,000 with spouse or spousal equivalent) for the past two years, or holders of certain professional certifications (Series 7, 65, or 82 licenses).

• You must be at least 18 years of age and have the legal capacity to enter into binding agreements in your jurisdiction.
• You must not be a resident or national of a jurisdiction subject to U.S. sanctions, nor be listed on the OFAC Specially Designated Nationals List or similar sanctions lists.

2. Account and Authentication

Access to the Platform requires authentication through Google OAuth. By signing in, you authorize us to receive your name, email address, and profile image from Google for account creation and authentication purposes.

You are responsible for maintaining the security of your Google account and for all activities that occur under your account on the Platform. You agree to notify us immediately at [email protected] if you become aware of any unauthorized access to or use of your account.

We reserve the right to suspend or terminate your account if we reasonably believe it has been compromised or is being used in violation of these Terms.

3. Fund Enrollment and Subscription Agreements

The Platform facilitates the enrollment process for limited partnership interests in Region Cuatro, LP. By completing the enrollment process and executing a Subscription Agreement, you acknowledge and agree to the following:

• Binding Agreement: Your executed Subscription Agreement is a legally binding contract. Your capital commitment is irrevocable upon execution except as provided in the Limited Partnership Agreement.
• Electronic Signatures: You consent to executing the Subscription Agreement and related tax forms (IRS Form W-9 or W-8BEN/W-8BEN-E) electronically through DocuSign or Documenso. Pursuant to the Electronic Signatures in Global and National Commerce Act (ESIGN) and the Uniform Electronic Transactions Act (UETA), your electronic signature has the same legal effect as a handwritten signature.
• Electronic Communications: You consent to receive all investor communications electronically, including capital call notices, distribution notices, Schedule K-1 tax documents, quarterly fund reports, and other investor correspondence.
• Accuracy of Information: You represent that all information provided during enrollment is true, accurate, and complete. You agree to promptly update any information that changes.

4. Financial Services and Bank Account Linking

The Platform offers optional bank account linking through Plaid, Inc. ("Plaid") to facilitate capital calls and fund distributions. By choosing to link your bank account, you acknowledge and agree to the following:

• Optional Service: Linking a bank account via Plaid is optional. You may choose to fund capital calls and receive distributions through other means (such as wire transfer) without linking a bank account.
• Plaid's Terms: Your use of Plaid is subject to Plaid's End User Privacy Policy and Terms of Service. By connecting your bank account, you authorize Plaid to access your financial institution on your behalf.
• Limited Data Storage: We store only your financial institution name, a masked account number (last four digits), account holder name, account type, and an encrypted Plaid access token. We do not store your bank login credentials, full account numbers, balances, or transaction history.
• Purpose: Linked bank account information is used solely for processing capital calls and distributing fund proceeds. It is not used for any other purpose.
• Revocation: You may revoke Plaid access at any time by contacting us at [email protected]. Upon revocation, we will delete the Plaid access token and associated bank account information, except where retention is required for completed transaction records or regulatory compliance.

5. Capital Commitment and Funding

By executing the Subscription Agreement, you agree to make a capital commitment to the Fund that will be drawn down over a subscription period. Important terms include:

• Irrevocable Commitment: Your capital commitment is irrevocable upon execution of the Subscription Agreement. You cannot withdraw or reduce your commitment except as provided in the Limited Partnership Agreement.
• Capital Calls: The General Partner will issue capital call notices specifying the amount due and the payment deadline. You are obligated to fund capital calls when due. Failure to fund may result in penalties as specified in the Limited Partnership Agreement, including potential forfeiture of your interest.
• Payment Methods: Capital contributions may be funded via wire transfer to the Fund's designated bank account or, if you have linked a bank account via Plaid, through the Platform. Wire instructions will be provided with each capital call notice.

6. Investment Risks

Investing in Region Cuatro, LP involves a high degree of risk. By using this Platform and investing in the Fund, you acknowledge and agree that:

• Risk of Loss: You may lose all or a substantial portion of your capital commitment. Investments in early-stage technology companies through venture capital are highly speculative.
• Illiquidity: Your limited partnership interest is not freely transferable. There is no public market for these interests, and transfer restrictions in the Limited Partnership Agreement apply. You should not invest unless you can hold your investment for the full fund life (typically 10 or more years).
• No Guarantee of Returns: Past performance is not indicative of future results. There is no guarantee that the Fund will achieve its investment objectives, generate profits, or return any capital.
• Concentration Risk: The Fund invests in early-stage technology companies. The majority of startup investments may result in partial or complete loss, with returns dependent on the success of a small number of portfolio companies.
• Manager Discretion: The General Partner has broad discretion over investment decisions. Your investment is passive, and you have limited control or voting rights as specified in the Limited Partnership Agreement.
• Not Investment Advice: Nothing on this Platform constitutes investment advice, financial advice, or a recommendation to invest. You should consult with your own financial, legal, and tax advisors before making any investment decision.

7. No Public Offer or Solicitation

Nothing on this Platform constitutes an offer to sell or a solicitation of an offer to buy any securities in any jurisdiction where such offer or solicitation would be unlawful. Limited partnership interests in Region Cuatro, LP have not been registered under the Securities Act of 1933 or any state securities laws and are being offered in reliance upon exemptions provided by Section 4(a)(2) and Rule 506(b) of Regulation D. Any investment opportunity described on this Platform is available only to accredited investors who have received appropriate offering documents.

9. Confidentiality

You agree to maintain the confidentiality of all non-public information provided to you through this Platform, including fund performance data, portfolio company information, deal pipeline submissions, investment terms, and other proprietary information. This obligation survives termination of your use of the Platform and remains in effect for as long as such information remains confidential.
