The Company is offering the Units at a price of $3.20 per Unit.

The Units are being offered on a "best efforts" basis and there is no requirement for a minimum amount of subscriptions. The Units are being offered for sale pursuant to a Private Placement Memorandum dated May 5, 1999 (the "Memorandum"), as more particularly described and set forth therein. Unless otherwise indicated, terms used herein shall have the same meanings as set forth in the Memorandum.

Subscriptions need not be accepted in the order received, and the Units may be allocated in whole or in part, at the sole discretion of the Company, in the event of an oversubscription.

The Units are being offered on a "best efforts" basis, and there is no requirement for the sale of a minimum amount of Units. There is no assurance that the Company will be able to sell all or any portion of the Units, and the number of Units which will actually be sold by the Company in the Offering is unknown.

3. Representations and Warranties of the Undersigned. The undersigned makes the following representations and warranties, together with the representations made by the undersigned in the Purchaser Questionnaire attached hereto (which representations are incorporated herein by this

reference), with the intent that they be relied upon by the Company and its counsel, officers, directors, employees and agents in determining the undersigned's suitability as a purchaser of the Units. The undersigned hereby agrees that such representations and warranties shall survive his/her purchase of the Units. By signing this Agreement, the undersigned represents that he/she has read and acknowledged the representations set forth in this Section 3. If more than one person is signing this Agreement, each representation and warranty made herein shall be a joint and several representation or warranty of each person.

(a) The undersigned is the sole and true party in interest, is acquiring the Units for his/her own account for investment, is not purchasing the Units subscribed for hereby for the benefit of any other person, and has no present intention of holding or managing the Units with others or of selling, distributing or otherwise disposing of any portion of the Units.

(b) The undersigned has consulted with the advisor (the "Purchaser Representative"), if any, named in the Purchaser Questionnaire incorporated herein. The Purchaser Representative, if any, has advised the undersigned as to the merits and risks of the investment in the Units in general and the suitability of the investment for the undersigned in particular.

(d) The undersigned is aware that an investment in the Units is highly speculative and subject to substantial risks. The undersigned has adequate means of providing for his/her current needs and possible contingencies, and is able to bear the high degree of economic risk of this investment, including, but not limited to, the possibility of the complete loss of the undersigned's entire investment and the limited transferability of the Units, which may make the liquidation of this investment impossible for the indefinite future.

(e) The undersigned, or the undersigned together with the Purchaser Representative, if any, have such knowledge and experience in financial and business matters as to be capable of evaluating the merits and risks of an investment in the Units and making an informed investment decision.

The undersigned understands and agrees that the Securities, or any interest therein, may not be resold or otherwise disposed of by the undersigned unless such Securities are subsequently registered under the 1933 Act and under all applicable state securities laws or unless the Company receives an opinion of counsel satisfactory to it that an exemption from registration is available.

Nonetheless, the undersigned will have certain limited registration rights to the extent such rights are expressly provided by a registration rights agreement (the "Registration Rights Agreement") executed in connection with this Agreement by the undersigned and the Company. Such registration rights consist of certain "piggyback" rights to obligate the Company to register Shares or Warrant Shares upon request of the holder thereof if the Company otherwise registers securities of the Company, except in specific circumstances set forth in the Registration Rights Agreement.

(h) The undersigned acknowledges and represents that he/she and the Purchaser Representative, if any, have received and reviewed a copy of the Memorandum and any amendments or supplements thereto, have been given a reasonable opportunity to review all documents, books and records of the Company pertaining to this investment, have been supplied with all additional information concerning the Company and the Units that has been requested by the undersigned, have had a reasonable opportunity to ask questions of and receive answers from the Company or its representatives concerning this investment, and that all such questions have been answered to the full satisfaction of the undersigned.

In making his/her decision to purchase the Units, the undersigned has relied solely upon his/her review of the Memorandum, this Agreement, and independent investigations made by him/her or his/her representatives without assistance of the Company or any of its officers, directors, employees or agents.

(j) The undersigned understands and agrees that the following restrictions and limitations are applicable to his/her purchases and resales, pledges, hypothecations or other transfers of the Securities:

TRANSFERABILITY OF THE SECURITIES IS THEREFORE LIMITED AND INVESTORS MUST BEAR THE ECONOMIC RISK OF THEIR INVESTMENT FOR AN INDEFINITE PERIOD OF TIME.
