             (f) Purchaser hereby represents and warrants to, and covenants
with, the Company that:

                 (i) Purchaser has reviewed the SEC Filings. The Company has
given Purchaser the opportunity to review any of the Company's other filings
with the SEC.

                 (ii) In connection with the issuance to Purchaser of the
     Purchased Shares, Purchaser hereby acknowledges and understands that the
     Purchased Shares have not been registered under the United States
     Securities Act of 1933, as amended (the "Federal Act"), the Texas
     Securities Act, as amended (the "Texas Act"), or any securities acts of
     any other state or country (the "Other Acts"), that the Purchased Shares
     are being issued to Purchaser in reliance upon one or more exemptions
     from registration contained in the Federal Act, the Texas Act, and



<PAGE>



     the Other Acts, and that the Company's reliance on such exemptions is
     based in part upon the representations made herein by Purchaser.

                 (iii) Purchaser hereby represents to the Company that
     Purchaser is acquiring the Purchased Shares solely for Purchaser's own
     account for investment and not with a view to, or for offer or sale in
     connection with, the unregistered "distribution" of all or any part of
     the Purchased Shares within the meaning of the Federal Act. Purchaser
     represents that he has no current intention to sell, convey, dispose of,
     or otherwise distribute any interest in or risk related to the Purchased
     Shares. Purchaser acknowledges and agrees that this transaction has not
     been reviewed or approved by the SEC or any other governmental agency or
     department.

                 (iv) Purchaser hereby acknowledges that the provisions of
     Rule 144 promulgated under the Federal Act ("Rule 144") are not now
     available for the public resale of the Purchased Shares and that
     Purchaser has no right to have the Purchased Shares registered under the
     Federal Act to permit them to be resold. Purchaser also hereby
     acknowledges that, as a result of the foregoing, Purchaser must hold the
     Purchased Shares for at least one (1) year from issuance (unless
     subsequently registered prior to that time) assuming the entire risk of
     investment therein for that period of time, until and unless (A) the
     Purchased Shares are subsequently registered under the Federal Act, (B)
     the Purchased Shares may be sold under Rule 144, or (C) an exemption from
     registration is available at the time of resale of the Purchased Shares.
     Purchaser is aware of the provisions of Rule 144 which permits limited
     resale of shares purchased in a private placement subject to the
     satisfaction of certain conditions, including, among other things, the
     existence of a public market for such shares, the availability of certain
     current public information about the issuer of such shares, the resale
     occurring not less than one year after acquisition, the sale being
     through a "broker's transaction" or in transactions directly with a
     "market maker" (as provided by Rule 144(f)) and the number of shares
     being sold during any three-month period not exceeding specified
     limitations (unless the sale is within the requirements of Rule 144(k)).

                 (v) Purchaser hereby represents to the Company that Purchaser
     has such knowledge and experience in financial and business matters that
     Purchaser is capable of evaluating the merits and risks of investing in
     the Purchased Shares and that Purchaser is able to bear the economic
     risk, including a total loss, of such an investment. Purchaser
     understands and has fully considered for purposes of this investment the
     risks of this investment and that, because of the restrictions on
     transfer, it may not be possible for Purchaser to liquidate Purchaser's
     investment in the Purchased Shares in the case of emergency.

                 (vi) Purchaser acknowledges and agrees that Purchaser is
     acquiring the Purchased Shares without being offered or furnished any
     offering literature or prospectus other than the SEC Filings. Purchaser
     hereby acknowledges that Purchaser has had access to all information,
     which Purchaser considers necessary or advisable to enable Purchaser to
     make an informed decision concerning the acquisition of the Purchased
     Shares. Purchaser is acquiring the Purchased Shares based solely on
     Purchaser's review of the SEC Filings and Purchaser's investigation of,
     and satisfaction with, the Company's current and anticipated financial
     condition and assets and not based on any oral representations of any
     individual. Purchaser confirms that Purchaser and Purchaser's
     representatives and advisors have been given the opportunity to ask
     questions of, and to receive answers from, persons acting on behalf of
     the Company concerning the business and prospects of the Company and to
     obtain any additional information, to the extent such persons possess
     such information or can acquire it without unreasonable effort or expense
     and without breach of confidentiality obligations, necessary to verify
     the accuracy of the information set forth in the SEC Filings.

                 (vii) Purchaser understands that Purchaser must not, and
     Purchaser agrees that Purchaser will not, sell, transfer, assign,
     encumber, or otherwise dispose of the Purchased Shares or any interest
     therein, unless prior thereto Purchaser has delivered to the Company, and
     the Company has accepted as satisfactory, an opinion of experienced and
     competent counsel to the effect that such proposed sale, transfer,
     assignment, encumbrance, or disposition will not constitute or result in
     any violation of the Federal Act, the Texas Act, the Other Acts, or any
     other applicable statute relating to the disposition of securities.

                 (viii) Purchaser understands and agrees that there may be
     typed or otherwise printed on the certificates representing the Purchased
     Shares, and any other securities issued in respect of the Purchased
     Shares upon any stock split, stock dividend, recapitalization, merger,
     consolidation, or similar event, a legend referring to the foregoing
     restriction upon disposition, such legend to be substantially in the
     following form (in addition to any other legends required by applicable
     law):

                  THE PURCHASED SHARES EVIDENCED BY THIS CERTIFICATE HAVE BEEN
         ACQUIRED FOR INVESTMENT AND HAVE NOT BEEN REGISTERED UNDER THE
         SECURITIES ACT OF 1933 (THE "ACT") OR UNDER ANY APPLICABLE STATE LAW,
         AND SUCH PURCHASED SHARES MAY NOT BE SOLD, TRANSFERRED, ASSIGNED, OR
         OTHERWISE DISPOSED OF UNLESS A REGISTRATION STATEMENT UNDER THE ACT
         WITH RESPECT TO SUCH DISPOSITION SHALL THEN BE IN EFFECT OR UNLESS THE
         PERSON REQUESTING THE TRANSFER OF SUCH PURCHASED SHARES SHALL FURNISH,
         WITH RESPECT TO SUCH TRANSFER, AN OPINION OP COUNSEL (BOTH COUNSEL AND
         OPINION TO BE SATISFACTORY TO THE CORPORATION) TO THE EFFECT THAT SUCH
         SALE, TRANSFER, ASSIGNMENT, OR DISPOSITION WILL NOT INVOLVE ANY
         VIOLATION OF THE ACT OR ANY APPLICABLE STATE LAW.

                 (ix) Purchaser also understands that the Company's Transfer
     Agent, the keeper of the Company's stock transfer books and records, has
     been instructed not to transfer the Purchased Shares except upon the
     Company's instructions for one (1) year from issuance (and transfers
     during the second year after issuance must be in accordance with Rule
     144) and that the Company will take such other steps as the Company deems
     necessary to prevent the transfer of the Purchased Shares in the absence
     of compliance with the foregoing restrictions.

                 (x) Purchaser represents to the Company that Purchaser is an
     "accredited investor" under Rule 501 of Regulation D of the Federal Act,
     and that the sale of the Purchased Shares to Purchaser is predicated, in
     part, on Regulation D, which addresses the limited sale of unregistered
     securities.

                 (xi) Purchaser acknowledges that Purchaser has received
     certain financial projections for the Company (the "Financial
     Projections"). Purchaser understands that there is no guarantee or
     assurance that the Company's operations will meet the Financial
     Projections. Purchaser further understands that the Financial Projections
     are subject to a number of factors, most of which are outside the
     Company's control. The Financial Projections involve risks and
     uncertainties and actual results may differ materially from the Financial
     Projections, Investor acknowledges that the Financial Projections should
     not be relied upon as indicative of the Company's future performance.
