                             CLOSING DATE; DELIVERY

         2.1 CLOSING DATE. The Closing of the purchase and sale of the Shares
hereunder (the "Closing") shall be held at the offices of Jose L. Lindner, at
11:00 a.m. (Central Standard time), April 1, 2003, or at such other time and

being hereinafter referred to as the "Closing Date").

         2.2 DELIVERY OF SHARES. At the Closing, the Company will deliver to the
Purchaser a certificate or certificates representing the Shares against payment
of the aggregate purchase price of Six Hundred Thousand Dollars ($600,000) by
wire transfer of immediately available funds to an account designated by the
Company. The certificate or certificates representing the Shares and the shares
of Common Stock issuable upon conversion of the Shares shall be subject to a
legend restricting transfer under the Securities Act of 1933, as amended (the
"Securities Act"), and referring to restrictions on transfer herein, such legend
to be substantially as follows:

         "The shares represented by this certificate have been acquired for
         investment and have not been registered under the Securities Act of
         1933, as amended. Such shares may not be sold or transferred in the
         absence of such registration or an opinion of counsel reasonably
         satisfactory to the Company as to the availability of an exemption from
         registration.

         The shares represented by this certificate are subject to restrictions
         on transfer, including any sale, pledge or other hypothecation, set
         forth in an agreement dated as of April 1, 2003 between the Company and
         LISEN, LLC, a copy of which agreement may be obtained at no cost by
         written request made by the holder of record of this certificate to the
         secretary of the Company at the Company's principal executive offices."

The Company agrees (i) to remove the legend set forth in the second preceding
paragraph upon receipt of an opinion of counsel in form and substance reasonably
satisfactory to the Company that the Shares or the shares of Common Stock
issuable upon conversion of the Shares are eligible for transfer without
registration under the Securities Act and (ii) to remove the legend set forth in
the immediately preceding paragraph at such time as the Shares (or the shares of
Common Stock issuable upon conversion of the Shares) may be transferred in
compliance with Section 8 or upon the termination of the covenants of Section 8
as provided for in Section 9.4.

standing under such laws. The Company has the requisite corporate power to own
and operate its properties and assets and to carry on its business as presently

limitations of public policy as they may apply to Section 4 of the Registration
Rights Agreement. Upon their issuance and delivery pursuant to this Agreement,
the Shares will be validly issued, fully paid and nonassessable. The issuance
and sale of the Shares will not give rise to any preemptive rights or rights of

         4.3 NO CONFLICT. The execution and delivery of this Agreement and the
Registration Rights Agreement do not, and the consummation of the transactions
contemplated hereby and thereby will not, conflict with, or result in any
violation of, or default (with or without notice or lapse of time, or both), or

or materially impair or restrict the Company's power to perform its obligations
as contemplated under said Agreements.

         4.4 INVESTMENT. The Purchaser is acquiring the Shares for investment
for its own account, not as a nominee or agent, and not with a view to, or for
resale in connection with, any distribution thereof. The Purchaser understands
that the Shares have not been registered under the Securities Act by reason of a
specific exemption from the registration provisions of the Securities Act which
depends upon, among other things, the bona fide nature of the investment intent
and the accuracy of the Purchaser's representations and warranties contained
herein.

         4.5 DISCLOSURE OF INFORMATION. The Purchaser has had full access to all
information it considers necessary or appropriate to make an informed investment
decision with respect to the Shares to be purchased by the Purchaser under this
Agreement. The Purchaser further has had an opportunity to ask questions and
receive answers from the Company regarding the terms and conditions of the
offering of the Shares and to obtain additional information necessary to verify
any information furnished to the Purchaser or to which the Purchaser had access.

         4.6 INVESTMENT EXPERIENCE. The Purchaser understands that the purchase
of the Shares involves substantial risk. The Purchaser has experience as an
investor in securities of companies and acknowledges that it is able to fend for
himself, can bear the economic risk of its investment in the Shares and has such
knowledge and experience in financial or business matters that it is capable of
evaluating the merits and risks of this investment in the Shares and protecting
its own interests in connection with this investment.

         4.7 ACCREDITED INVESTOR STATUS. The Purchaser is an "accredited
investor" within the meaning of Regulation D promulgated under the Securities
Act.

         4.8 RESTRICTED SECURITIES. The Purchaser understands that the Shares to
be purchased by the Purchaser hereunder are characterized as "restricted
securities" under the Securities Act inasmuch as they are being acquired from
the Company in a transaction not involving a public offering and that under the
Securities Act and applicable regulations thereunder such securities may be
resold without registration under the Securities Act only in certain limited
circumstances. The Purchaser is familiar with Rule 144 of the SEC, as presently
in effect, and understands the resale limitations imposed thereby and by the
Securities Act. The Purchaser understands that the Company is under no
obligation to register any of the Shares sold hereunder except as provided in
the Registration Rights Agreement.

convertible (except as otherwise provided in this Agreement).

         5.5 REGISTRATION RIGHTS AGREEMENT. The Company shall have executed and
delivered the Registration Rights Agreement substantially in the form attached

         8.1 RIGHT OF FIRST REFUSAL. Prior to making any sale or transfer of the
Shares (other than a sale or transfer registered under the Securities Act or
pursuant to Rule 144, or a sale or transfer of that number of Shares
representing less than three percent (3%) of the Company's outstanding Common
Stock, as converted, to any person or group), the Purchaser shall give the
Company the opportunity to purchase such Shares in the following manner:

                  (i) The Purchaser shall give notice (the "Transfer Notice") to
         the Company in writing of such intention specifying the approximate
         number of the proposed purchasers or transferees, the amount of Shares
         proposed to be sold or transferred, the proposed price per share
         therefor (the "Transfer Price") and the other material terms upon which
         such disposition is proposed to be made.

                  (ii) The Company shall have the right, exercisable by written
         notice given by the Company to the Purchaser within five (5) business
         days after receipt of such Transfer Notice, to purchase all but not
         part of the Shares specified in such Transfer Notice for cash per share
         equal to the Transfer Price, provided, within five (5) business days
         after written notice of exercise by the Company, the Company shall
         provide the Purchaser with evidence satisfactory to the Purchaser (by
         written commitment letter subject only to customary representations,
         diligence and documentation, letter of credit or otherwise) of its
         ability to finance such repurchase.

                  (iii) If the Company exercises its right of first refusal
         hereunder, the closing of the purchase of the Shares with respect to
         which such right has been exercised shall take place within ten (10)
         business days after the Company gives notice of such exercise. Upon
         exercise of its right of first refusal, the Company and the Purchaser
         shall be legally obligated to consummate the purchase contemplated
         thereby and shall use their best efforts to secure any approvals
         required in connection therewith.

                  (iv) If the Company does not exercise its right of first
         refusal hereunder within the time specified for such exercise, the
         Purchaser shall be free, during the period of ninety (90) calendar days
         following the expiration of such time for exercise, to sell the Shares
         specified in such Transfer Notice on terms no less favorable to the
         Purchaser than the terms specified in such Transfer Notice.

                                       6
<PAGE>

         8.2 ACTS IN CONCERT WITH OTHERS. Except as contemplated herein with
regard to permissible sales of the Purchaser's Shares, the Purchaser shall not
join a partnership, limited partnership, syndicate or other group, or otherwise
act in concert with any Person, for the purpose of acquiring, holding or
disposing of Shares of the Company owned by the Purchaser.

         8.3 RESTRICTIONS ON TRANSFER OF SHARES. For a period of one year from
the date of this Agreement, the Purchaser shall not, directly or indirectly,
sell, transfer, pledge or hypothecate any Shares (or shares of Common Stock
received upon the conversion of the Shares) owned by it except (i) to the
Company or any person or group approved in writing by the Company, or (ii) to a
corporation of which the Purchaser owns not less than 50% of the voting power
entitled to be cast in the election of directors (a "Controlled Corporation"),
so long as such Controlled Corporation agrees to hold such Shares subject to all
the provisions of this Agreement, including this Section 8.6, and agrees to
transfer such Shares to the Purchaser or another Controlled Corporation of the
Purchaser if it ceases to be a Controlled Corporation of the Purchaser.
Notwithstanding the foregoing or anything else to the contrary in this
Agreement, the Purchaser may enter into bona fide transactions through a
nationally recognized investment banking firm which constitute a hedge against
changes in the market price of the Common Stock, provided, however, no public
disclosure is made with respect to such hedge transactions, except in an initial
Schedule 13D, the text of which is reasonably satisfactory to the Company, or if
in the opinion of counsel to Purchaser such disclosure is required as a matter
of law.

         8.4 ACQUISITION OF STOCK. The Purchaser shall advise management of the
Company as to the Purchaser's general plans to acquire shares of Common Stock,
or rights thereto, reasonably in advance of any such acquisitions. All of the
Purchaser's purchases of Common Stock shall be in compliance with applicable
laws and regulations and the provisions of this Agreement.
