INVESTMENT REPRESENTATION LETTER

(TO BE SIGNED BY EACH ACCEPTING NCOAT SHAREHOLDER)

Tylerstone Ventures Corporation

Re: Purchase of shares of Common Stock of Tylerstone Ventures Corporation

Gentlemen:

In connection with the acquisition by the undersigned of shares of Common Stock of Tylerstone Ventures Corporation (the “Securities”), the undersigned represents that the Securities are being acquired without a view to, or for, resale in connection with any distribution of such Securities or any interest therein without registration or other compliance under the Securities Act of 1933, as amended (the "Securities Act"), and that the undersigned has no direct or indirect participation in any such undertaking or in the underwriting of such an undertaking.

The undersigned understands that the Securities have not been registered, but are being acquired by reason of a specific exemption under the Securities Act as well as under certain state statutes for transactions by an issuer not involving any public offering and that any disposition of the subject Securities may, under certain circumstances, be inconsistent with this exemption and may make the undersigned an "underwriter" within the meaning of the Securities Act. It is understood that the definition of an "underwriter" focuses on the concept of "distribution" and that any subsequent disposition of the subject Securities can only be effected in transactions which are not considered distributions. Generally, the term "distribution" is considered synonymous with "public offering" or any other offer or sale involving general solicitation or general advertising. Under present law, in determining whether a distribution occurs when securities are sold into the public market, under certain circumstances one must consider the availability of public information regarding the issuer, a holding period for the securities sufficient to assure that the persons desiring to sell the securities without registration first bear the economic risk of their investment, and a limitation on the number of securities which the stockholder is permitted to sell and on the manner of sale, thereby reducing the potential impact of the sale on the trading markets. These criteria are set forth specifically in rule 144 promulgated under the Securities Act. After one year from the date the Securities are fully paid for and the subscription is accepted by the issuer, all as calculated in accordance with rule 144(d), sales of the Securities in reliance on rule 144 can only be made in limited amounts in accordance with the terms and conditions of that rule. After two year from the date the Securities are fully paid for, as calculated in accordance with rule 144(d), it can generally be sold without meeting these conditions provided the holder is not (and has not been for the preceding three months) an affiliate of the issuer.

The undersigned acknowledges that the Securities must be held and may not be sold, transferred, or otherwise disposed of for value unless it is subsequently registered under the Securities Act or an exemption from such registration is available; the issuer is under no obligation to register the Securities under the Securities Act or under section 12 of the Securities Exchange Act of 1934, as amended, except as may be expressly agreed to by it in writing; if rule 144 is available, and no assurance is given that it will be, initially only routine sales of such Securities in limited amounts can be made in reliance on rule 144 in accordance with the terms and conditions of that rule; the issuer is under no obligation to the undersigned to make rule 144 available, except as may be expressly agreed to by it in writing; in the event rule 144 is not available, compliance with regulation A or some other exemption may be required before the undersigned can sell, transfer, or otherwise dispose of such Securities without registration under the Securities Act; the issuer's registrar and transfer agent will maintain a stop transfer order against the registration of transfer of the Securities; and the certificate representing the convertible promissory notes and warrants composing the Securities will bear a legend in substantially the following form so restricting the sale of such Securities.

THE SECURITIES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS AMENDED (THE "SECURITIES ACT"), AND ARE "RESTRICTED SECURITIES" WITHIN THE MEANING OF RULE 144 PROMULGATED UNDER THE SECURITIES ACT. THE SECURITIES HAVE BEEN ACQUIRED FOR INVESTMENT AND MAY NOT BE SOLD OR TRANSFERRED WITHOUT COMPLYING WITH RULE 144 IN THE ABSENCE OF AN EFFECTIVE REGISTRATION OR OTHER COMPLIANCE UNDER THE SECURITIES ACT.

The issuer may refuse to register transfer of the Securities in the absence of compliance with rule 144 unless the undersigned furnishes the issuer with a "no-action" or interpretative letter from the Securities and Exchange Commission or an opinion of counsel reasonably acceptable to the issuer stating that the transfer is proper; further, unless such letter or opinion states that the Securities are free of any restrictions under the Securities Act, the issuer may refuse to transfer the Securities to any transferee who does not furnish in writing to the issuer the same representations and agree to the same conditions with respect to such Securities as are set forth herein. The issuer may also refuse to transfer the Securities if any circumstances are present reasonably indicating that the transferee's representations are not accurate.

	Very truly yours,

Dated: ________________________		________________________________ (Subscriber)
