The Purchase Price is set forth on the signature page hereto. The Shares are being offered pursuant to an offering statement on Form 1-A, File No. 024-10855 (the “Offering Statement”). The Offering Statement will have been qualified by the Securities and Exchange Commission (the “Commission”) prior to issuance of any Shares and acceptance of Investor’s subscription. The offering circular (the “Offering Circular”) which forms a part of the Offering Statement, however, is subject to change. A final Offering Circular and/or supplement to Offering Circular will be delivered to the Investor as required by law. The Shares are being offered by Boustead Securities, LLC (the “Underwriter”) as underwriter on a “best efforts, minimum/maximum” basis. The completion of the purchase and sale of the Shares (the “Closing”) shall take place at a place and time (the “Closing Date”) to be specified by the Company and Underwriter in accordance with Rule 15c6-1 promulgated under the Securities Exchange Act of 1934, as amended (the “Exchange Act”).

The Purchase Price for the Shares shall be paid simultaneously with the execution and delivery to the Company of the signature page of this Subscription Agreement. Subscriber shall deliver a signed copy of this Subscription Agreement, along with payment for the aggregate Purchase Price of the Shares by a check for available funds made payable to “FinTech Clearing, LLC as Agent for the Investors in the CNS Securities Offering”, by ACH electronic transfer or wire transfer to an account designated by the Company, or by any combination of such methods.

Payment for the Shares shall be received by FinTech Clearing, LLC (the “Offering Deposit Account Agent”) from the undersigned by transfer of immediately available funds, check or other means approved by the Company at least two days prior to the closing date, in the amount as set forth on the signature page hereto. Upon satisfaction or waiver of all the conditions to closing set forth in the Underwriting Agreement and Offering Statement, at the Closing, (i) the Offering Deposit Account Agent shall release such funds to the Company, and (ii) the Company shall cause the Shares to be delivered to the Investor with the delivery of the Shares to be made through the facilities of The Depository Trust Company’s DWAC system in accordance with the instructions set forth on the signature page attached hereto under the heading “DWAC Instructions.”

The Underwriter and any participating broker dealers (the “Members”) shall confirm, via the selected dealer agreement or master selected dealer agreement that it will comply with Exchange Act Rule 15c2-4. As per Exchange Act Rule 15c2-4 and FINRA Notice to Members Rule 84-7 (the “Rule”), all checks that are accompanied by a subscription agreement will be promptly sent along with the subscription agreements to the escrow account by noon the next business day. In regard to monies being wired from an investor’s bank account, the Members shall request the investors send their wires by the next business day, however, the Company cannot insure the investors will forward their respective monies as per the Rule. In regard to monies being sent from an investor’s account held at the participating broker, the funds will be “promptly transmitted” to the escrow agent following the receipt of a completed subscription document and completed wire instructions by the investor to send funds to the escrow account. Absent unusual circumstances, funds in customer accounts will be transmitted by noon of the next business day. In the event that funds are sent in and the offering does not close for any reason prior to the offering termination date set forth in the final Offering Statement, all funds will be returned to investors promptly in accordance with the escrow agreement terms and applicable law.

2.       Certifications, Representations and Warranties

In order to induce the Company to accept this Subscription Agreement for the Shares and as further consideration for such acceptance, the undersigned hereby makes, adopts, confirms and agrees to all of the following covenants, acknowledgments, representations and warranties with the full knowledge that the Company and its affiliates will expressly rely thereon in making a decision to accept or reject this Subscription Agreement:

I understand that to purchase Shares, I must either be an “accredited investor” as such term is defined in Rule 501 of Regulation D promulgated under the Securities Act of 1933, as amended, or I must limit my investment in the Shares to a maximum of: (i) 10% of my net worth or annual income, whichever is greater, if I am a natural person; or (ii) 10% of my revenues or net assets, whichever is greater, for my most recently completed fiscal year, if I am a non-natural person.

I understand that if I am a natural person I should determine my net worth for purposes of these representations by calculating the difference between my total assets and total liabilities. I understand this calculation must exclude the value of my primary residence and may exclude any indebtedness secured by my primary residence (up to an amount equal to the value of my primary residence). In the case of fiduciary accounts, net worth and/or income suitability requirements may be satisfied by the beneficiary of the account or by the fiduciary, if the fiduciary directly or indirectly provides funds for the purchase of the Shares.

I hereby represent and warrant that I meet the qualifications to purchase Shares because:

I understand that the Company reserves the right to, in its sole discretion, accept or reject this Subscription, in whole or in part, for any reason whatsoever, and to the extent not accepted, unused funds transmitted herewith shall be returned to the undersigned in full, with any interest accrued thereon.

I have received the Offering Circular.

I am purchasing the Shares for my own account.

I hereby represent and warrant that I am not, and am not acting as an agent, representative, intermediary or nominee for any person identified on the list of blocked persons maintained by the Office of Foreign Assets Control, U.S. Department of Treasury. In addition, I have complied with all applicable U.S. laws, regulations, directives, and executive orders relating to anti-money laundering including but not limited to the following laws: (1) the Uniting and Strengthening America by Providing Appropriate Tools Required to Intercept and Obstruct Terrorism Act of 2001, Public Law 107-56; and (2) Executiv

e Order 13224 (Blocking Property and Prohibiting Transactions with Persons Who Commit, Threaten to Commit, or Support Terrorism) of September 23, 2001.

By making the foregoing representations you have not waived any right of action you may have under federal or state securities law. Any such waiver would be unenforceable. The Company will assert your representations as a defense in any subsequent litigation where such assertion would be relevant. This Subscription Agreement and all rights hereunder shall be governed by, and interpreted in accordance with, the laws of the State of New York without giving effect to the principles of conflict of laws.
