Attn: George R. Jensen, Jr.,
      Chief Executive Officer

Dear Mr. Jensen:

         The undersigned, DF INVESTMENT (hereinafter referred to as "the
undersigned", "I", or "my") understands that the Company is offering for sale
(the "Offering") up to 2,000,000 shares of restricted Common Stock of the
Company ("Common Stock") at U.S. $1.50 per share. The Offering consists of 20
units at a price of U.S. $150,000 per unit ("Unit"), with each Unit consisting
of 100,000 shares of Common Stock. The Offering will terminate on June 15, 2000
and the minimum purchase by the undersigned is one Unit. Promptly following the
termination of the Offering, the Company shall file and use its best efforts to
have declared effective, an appropriate registration statement with the United
States Securities and Exchange Commission ("Commission") registering all of the
shares of Common Stock sold in the Offering for resale by the undersigned under
the Securities Act of 1933, as amended (the "Act").

                  1. Subscription. The undersigned hereby subscribes to become a
shareholder in the Company, and to purchase the number of Units in the Company
indicated below in accordance with the terms and conditions of the Offering
Materials (as defined below). I understand that this subscription for Units may
be rejected at the discretion of the Company, and that I must qualify as an
"accredited investor" under Regulation D, as promulgated by the Commission under
the Act.

Investor" under Regulation D. I understand that in order to subscribe for Units
in the Offering, I must be an "accredited investor" as defined in Section 501 of
Regulation D under the Act and hereby represent and warrant to the Company that
I am an "accredited investor." In this regard, the undersigned is an "accredited
investor" by virtue of qualifying under one of the following categories (check

                  in each of those years, and has a reasonable expectation of
                  reaching the same income level in 2000; or

                  _X_  the undersigned is a corporation or partnership not
                  formed for the purpose of investing in the Company with
                  total assets in excess of $5,000,000; or

                  ____the undersigned is an entity in which all the equity
                  owners are accredited investors each of which satisfy one of
                  the categories set forth herein; or

                  ____the undersigned is a bank as defined in Section 3(a)(2) of
                  the Act, or a broker-dealer registered pursuant to section 15
                  of the Securities Exchange Act of 1934, or an investment
                  company registered under the Investment Company Act of 1940.

         3. Representations by Undersigned.  The undersigned represents
and warrants to the Company as follows:

                  (a) I have received from the Company, read and understand the
         provisions of each of the following: (i) the Company's Annual Report on
         Form 10-KSB for the fiscal year ended June 30, 1999; and (ii) the
         Company's Form 10-QSB Quarterly Report for the quarterly period ended
         September 30, 1999; and (iii) the Company's Form 10-QSB Quarterly
         Report for the quarterly period ended December 31, 1999; and (iv) the
         Company's Form 10-QSB Quarterly Report for the quarterly period ended

                                        2

<PAGE>

         March 31, 2000; and (v) the Company's Form SB-2 Registration Statement
         filed with the Commission on April 18, 2000(File No. 333-35070); and
         (vi) the term sheet for this Offering dated June 5, 2000; and (vii) the
         Risk Factors section incorporated by reference herein in Section 3(i)
         hereof. I understand that all of the foregoing together with this
         Subscription Agreement shall be referred to herein as "Offering
         Materials".

                  (b) I have relied only upon the information presented and
         contained in the Offering Materials. I have had the opportunity to ask
         of the person or persons acting on behalf of the Company any and all
         relevant questions in connection with any aspect of the Company
         including, but not limited to, the Units offered by the Offering
         Materials and have received answers which I consider to be reasonably
         responsive to such questions. I have had the opportunity to verify the
         accuracy of the information contained in the Offering Materials.

                  (c) I understand that I am subscribing for Units without being
         furnished any literature or prospectus in connection with the Offering
         other than the Offering Materials, and that the Offering of Units
         presented in the Offering Materials will not have been scrutinized by
         the securities administrator or similar bureau, agency, or department
         of the state of my residence.

                  (d) I understand (i) that the Common Stock has not been
         registered under the Act or registered or qualified under the
         securities laws of the state of my residence, (ii) that I have no right
         to require such registration or qualification, and (iii) that therefore
         I must bear the economic risk of the investment for an indefinite
         period of time because the Common Stock may not be sold unless so
         registered or qualified or unless an exemption from such registration
         and qualification is available.

         Although the Company has agreed to use its best efforts to register for
         resale the Common Stock under the Act, and to use its best efforts to
         keep such registration statement current and effective, there can be no
         assurance that such efforts will be successful. In any such event, the
         Common Stock would not be registered for resale by the undersigned
         under the Act, and could only be sold by the undersigned in reliance
         upon exemptions from registration under the Act, or in accordance
         with Regulation S.

                                        3

                  (e) The Units are being purchased for my own account for
         investment purposes only and not for the interest of any other person
         and are not being purchased with a view to or for the resale,
         distribution, subdivision or fractionalization thereof. Although the
         Common Stock is currently traded on the OTC Bulletin Board under the
         symbol USTT, I also understand that there may not be any established
         public trading market for the sale of such securities.

                  (f) I am able to bear the economic risks related to purchase
         of the Unit(s) for an indefinite period of time (i.e., I am able to
         afford a complete loss of the Unit(s) I am subscribing to purchase).

                  (g) My overall commitment to investments which are not readily
         marketable is not disproportionate to my net worth and my investment in
         the Company will not cause such overall commitment to become excessive.

                  (h) I have adequate means of providing for my current needs
         and possible personal contingencies. I have no need for liquidity of
         the Unit(s) subscribed to be purchased hereby and have no reason to
         anticipate any change in my personal circumstances, financial or
         otherwise, which might cause or require any sale or distribution of
         such Unit(s) subscribed to be purchased.

                  (i) I recognize that the purchase of the Unit(s) involves a
         high degree of risk including those special risks set forth under the
         caption "Risk Factors" in the Form SB-2 Registration Statement of the
         Company filed with the Commission on April 18, 2000 (No. 333-35070) all
         of which are incorporated herein by reference.

                  (j) I understand that my right to transfer the Common Stock
         will be restricted as set forth on the stock certificates. Such
         restrictions include provisions against transfer unless such transfer
         is not in violation of the Act, or applicable state securities laws
         (including investor suitability standards).

                  (k) All information which I have provided to the Company
         including, but not limited to, my Social Security or tax

                                        4

         identification number, my financial position, and status as an
         accredited investor, and my knowledge of financial and business matters
         is true, correct and complete as of the date of execution of this
         Subscription Agreement. I undertake to provide promptly to the Company
         written notice of any material changes in my financial position or
         otherwise and such information will be true, correct and complete as of
         the date given. I understand that the Company will rely in a material
         degree upon the representations contained herein.

                  (l) The undersigned maintains a domicile or business at the
         address shown on the signature page of this Subscription Agreement, at
         which address the undersigned has subscribed for the Units.

                  (m) I understand that a legend shall be placed on any stock
         certificate representing the Common Stock substantially to the
         following effect:

SUBSTANCE SATISFACTORY TO THE CORPORATION) OF COUNSEL SATISFACTORY TO THE
CORPORATION, SUCH REGISTRATION IS NOT REQUIRED. HEDGING TRANSACTIONS INVOLVING
THESE SECURITIES MAY NOT BE CONDUCTED UNLESS IN COMPLIANCE WITH THE ACT.

                  (n) I understand that the Company may require me to meet
         additional suitability standards if it deems it necessary or advisable
         to comply with any applicable state securities or other laws.

                  (o) The undersigned certifies that it (i) is not a U.S.
         person and is not acquiring the securities for the account or
         benefit of any U.S. person, or (ii) is a U.S. person who
         purchased securities in a transaction that did not require
         registration under the Act.
