                               SECURITY AGREEMENT


         THIS SECURITY AGREEMENT (this "Security Agreement") is made and entered

Security Agreement to secure performance and payment of all obligations and
indebtedness of Debtor to the Secured Party, including, but not limited to, the
obligations and indebtedness of Debtor to the Secured Party described in Section

Indebtedness, Debtor hereby pledges to the Secured Party and grants to the

including, without limitation, all goods, merchandise, raw materials, goods in
process, finished goods and other tangible personal property both now owned and

         (e) All awards in respect of any "Taking" of any thereof (as used
herein, a "Taking" shall mean a taking, conveyance or sale of all or any part of

property of every character and wherever situated, now owned and hereafter
acquired by Debtor.

     3.  Payment Obligations of Debtor.

         (a) Debtor shall pay to the Secured Party any sum or sums due or which
may become due pursuant to any promissory note or notes now or hereafter
executed by Debtor to evidence Debtor's indebtedness to the Secured Party,
including, without limitation, the Secured Convertible Promissory Note of Debtor
dated as of even date herewith payable to the order of the Secured Party in the
original principal amount of Two Million and no/100's Dollars ($2,000,000.00)
(the "Note"), in accordance with the terms of such Note and the terms of this
Security Agreement, as well as all other indebtedness now due and owing the
Secured Party, and any and all indebtedness hereafter to become due and owing
the Secured Party, whether evidenced by note or otherwise, and any and all
renewals, rearrangements or extensions of said indebtedness.

         (b) Debtor shall account fully and faithfully to the Secured Party for
proceeds from disposition of the Collateral in any manner and, following an
Event of Default (as defined below) hereunder, shall pay or turn over promptly
in cash, negotiable instruments, drafts, assigned accounts or chattel paper all
the proceeds from each sale to be applied to Debtor's Indebtedness to the
Secured Party, subject, if other than cash, to final payment or collection.
Application of such proceeds to Indebtedness of Debtor shall be in the sole
discretion of the Secured Party, provided such application of proceeds is made
by the Secured Party in a reasonable manner.

         (c) Following an Event of Default hereunder or under the Note, Debtor
shall pay to the Secured Party on demand all expenses and expenditures
(including, but not limited to, reasonable fees and expenses of legal counsel)

lesser of (i) 18% per annum or (ii) the highest rate of interest then allowed by
law.

         (d) Debtor shall pay immediately, without notice, the entire unpaid
Indebtedness of Debtor to the Secured Party whether created or incurred pursuant

         (b) Except for the security interest granted in this Security
Agreement, no financing statement covering the Collateral or its proceeds is on
file in any public office and there is no lien, security interest or encumbrance
in or on the Collateral.

         (c) The location where Debtor maintains its chief executive office is
1121 East 7th Street, Austin, Texas 78701.

         (d) The Collateral shall remain in Debtor's possession or control at
all times at Debtor's risk of loss and be kept at the address shown in paragraph
4(c) above, where the Secured Party may inspect it at any time, except for its
temporary removal in connection with its ordinary use or unless Debtor notifies
the Secured Party in writing and the Secured Party consents in writing in
advance of its removal to another location.

         (e) Until an Event of Default, Debtor may use the Collateral in any
lawful manner not inconsistent with this Security Agreement or with the terms or
conditions of any policy of insurance thereon and except for accounts and
contract rights may also sell the Collateral in the ordinary course of business.
The Secured Party security interest shall attach to all proceeds of sales and
other dispositions of the Collateral.

         (f) Debtor will promptly notify the Secured Party in writing of any
change in the location of its chief executive office as set forth in paragraph
4(c) of this Security Agreement.

         (g) Debtor shall pay prior to delinquency all material taxes, charges,
liens and assessments against the Collateral except those Debtor is contesting
in good faith and for which adequate accruals have been made, and upon Debtor's
failure to do so after ten days' prior written notice, the Secured Party at its
option may pay any of them and shall be the sole judge of the legality or
validity thereof and the amount necessary to discharge the same. Such payment
shall become part of the Indebtedness secured by this Security Agreement and
shall be paid to the Secured Party by Debtor immediately and without demand,
with interest thereon at the rate set forth in paragraph 3(c) hereof.

         (h) Debtor will have and maintain insurance at all times with respect
to all Collateral against risks of fire, theft and such other risks as the
Secured Party may reasonably require, including extended coverage, and in the
case of motor vehicles, including collision coverage. Such insurance policies
shall also contain a standard mortgagee's endorsement providing for payment of
any loss to the Secured Party. All policies of insurance shall provide for ten
days' written minimum cancellation notice to the Secured Party. Debtor shall
furnish the Secured Party evidence of compliance with the foregoing insurance
provisions. Following an Event of Default, the Secured Party may act as
attorneys for Debtor in obtaining, adjusting, settling and canceling such
insurance and endorsing any drafts drawn by insurers of the Collateral. The
Secured Party may apply any proceeds of such insurance which may be received by
it in payment on account of the obligations secured hereby, whether due or not.

         (i) Debtor shall, at its own expense, do, make, procure, execute and
deliver all acts, things, writings and assurances as the Secured Party may at
any time reasonably request to protect, assure or enforce its interests, rights
and remedies created by, provided in or emanating from this Security Agreement.

         (j) Except in the ordinary course of business, Debtor shall not sell,
lend, rent, lease or otherwise dispose of the Collateral or any interest therein
except as authorized in this Security Agreement or in writing by the Secured
Party, and Debtor shall keep the Collateral, including the proceeds thereof,
free from unpaid charges, including taxes, and from liens, encumbrances and
security interests other than that of the Secured Party.

         (k) Debtor shall sign and execute alone or with the Secured Party any
Financing Statement or other document or procure any document and pay all
connected costs reasonably incurred, necessary to protect the security interest
under this Security Agreement against the rights or interests of third persons.

         (l) Debtor shall at all times keep the proceeds of the Collateral
separate and distinct from other property of Debtor and shall keep accurate and
complete records of the Collateral and its proceeds.

         (m) Debtor is the owner of the Collateral free of all liens, claims and
encumbrances, except as created by this Security Agreement and the security
interest granted in favor of the Secured Party, EXCEPT AS OTHERWISE SET FORTH ON
SCHEDULE A.

         (n) As to that portion of the Collateral which is accounts, Debtor
represents, warrants and agrees with respect to each such account that:

               (i) The account arose from the performance of services by Debtor
         which have been fully and satisfactorily performed or from the lease
         or the absolute sale of goods by Debtor in which Debtor had the sole
         and complete ownership, and the goods have been shipped or delivered
         to the account debtor.

               (ii) The account is not subject to any prior or subsequent
         assignment, claim, lien or security interest other than that of the
         Secured Party.

               (iii) The account is not subject to set-off, counterclaim,
         defense, allowance or adjustment other than discounts for prompt
         payment shown on the invoice, or to dispute, objection or complaint by
         the account debtor concerning his liability on the account, and the
         goods, the sale or lease of which gave rise to the account, have not
         been returned, rejected, lost or damaged.

               The account arose in the ordinary course of Debtor's business,
         and no notice of bankruptcy, insolvency or financial hardship of the
         account debtor has been received by Debtor.

         (o) Debtor further represents and warrants as follows:

               (i) Organization. Debtor is a corporation duly incorporated,
         validly existing and in good standing under the laws of its
         jurisdiction of organization. Debtor has the corporate power to own
         its properties and to


                                       4

<PAGE>   5

          carry on its business as now being conducted and as proposed to be
          conducted and is duly qualified to do business and is in good standing
          in each jurisdiction in which the failure to be so qualified and in
          good standing would have a material adverse effect on its business,
          financial condition, results of operations or prospects;

               (ii) Authority. Debtor has all requisite corporate power and
          authority to execute and deliver the Note and this Security Agreement
          and to carry out and perform its obligations thereunder and hereunder;

               (iii) No Conflicts. The execution, delivery and performance of
          the Note and this Security Agreement will not result in any violation
          of, conflict with, or constitute a breach or default or give rise to a
          right of termination, cancellation or acceleration under any provision
          of (A) Debtor's charter or governing documents; (B) any judgment,
          decree or order or any agreement, contract, understanding, indenture
          or other instrument to which Debtor is a party or by which it or its
          assets may be bound; or (C) any statute, rule or governmental
          regulation to which Debtor may be subject; and

               (iv) Enforceability. The Note and this Security Agreement
          constitute the valid and binding obligations of Debtor, enforceable
          against Debtor in accordance with their respective terms.

     5.   Events of Default. Debtor shall be in default under this Security
Agreement upon the happening of any condition or event set forth below (each, an
"Event of Default"):

          (a) Debtor's failure to pay any Indebtedness secured by this Security
Agreement within ten business days after such Indebtedness becomes due in
accordance with the terms of this Security Agreement or the Note.

          (b) Default by Debtor in punctual performance of any of the
obligations, covenants, terms or provisions contained or referred to in this
Security Agreement or in any note secured hereby, if such default shall continue
unremedied for a period of twenty business days following written notice of
default by the Secured Party to Debtor.

          (c) Any warranty, representation or statement contained in this
Security Agreement or made or furnished to the Secured Party by or on behalf of
Debtor in connection with this Security Agreement or to induce the Secured Party
to make a loan to Debtor proves to have been false in any material respect when
made or furnished.

          (d) Loss, theft, substantial damage, destruction, sale (except as
authorized in this Security Agreement) or encumbrance to or of any material
portion of the Collateral, or the making of any levy, seizure or attachment
thereof or thereon.

          (e) Debtor's dissolution, termination of existence, insolvency or
business failure; the appointment of a receiver of all or any part of the
property of Debtor; an assignment for the benefit of creditors by Debtor; or the

<PAGE>   6

bankruptcy or insolvency laws by or against Debtor or any guarantor, surety or
endorser for Debtor which results in the entry of an order for relief or which
remains undismissed, undischarged or unbonded for a period of 60 days or more.

          (f) Any statement of the financial condition of Debtor or of any
guarantor, surety or endorser of any liability of Debtor to the Secured Party
submitted to the Secured Party by Debtor or any such guarantor, surety or
endorser proves to be false in any material respect.

     6.   Secured Party' Rights and Remedies.

          (a) Rights Exclusive of Default.

               (i) This Security Agreement, the Secured Party's rights hereunder
          or the Indebtedness hereby secured may be assigned by the Secured
          Party (or any subsequent assignee) from time to time, and in any such
          case the assignee shall be entitled to all of the rights, privileges
          and remedies granted in this Security Agreement to the Secured Party;
          and in such event Debtor will assert no claims or defenses, other than
          a defense that it has performed its obligations under the Note and
          this Security Agreement, it may have against the Secured Party against
          the assignee, except those granted in this Security Agreement.

               (ii) The Secured Party may enter Debtor's premises at any
          reasonable time without interruption of Debtor's business and without
          any breach of the peace to inspect the Collateral and Debtor's books
          and records pertaining to the Collateral, and Debtor shall assist the
          Secured Party in making any such inspection; provided, that the
          Secured Party and its agents shall keep confidential all Debtor's
          proprietary information and confidential information and shall not use
          such proprietary information and confidential information except in
          connection with enforcing the Secured Party's rights under this
          Security Agreement or unless required to disclose such information
          pursuant to a judicial or governmental order.

               (iii) The Secured Party may execute, sign, endorse, transfer or
          deliver in the name of Debtor, notes, checks, drafts or other
          instruments for the payment of money and receipts, certificates of
          origin, applications for certificates of title or any other documents,
          necessary to evidence, perfect or upon an Event of Default realize
          upon the security interest and obligations created by this Security
          Agreement.

               (iv) At its option, the Secured Party may discharge taxes, liens
          or security interests or other encumbrances at any time levied or
          placed on the Collateral, may pay for the insurance on the Collateral
          and may pay for the maintenance and preservation of the Collateral.
          Debtor agrees to reimburse the Secured Party on demand for any payment
          made, or expense incurred by the Secured Party pursuant to the
          foregoing authorization, plus interest thereon at the rate set forth
          in paragraph 3(c) hereof.

          (b) Rights in Event of Default. In addition to any other rights which
the Secured Party may have at law or hereunder, upon the occurrence of an Event
of Default, and at any time thereafter, the Secured Party may:

               (i) Declare all obligations secured hereby immediately due and
          payable and shall have the rights and remedies of a "secured party"
          under the Texas Business and Commerce Code, including, without
          limitation, the right to sell, lease or otherwise dispose of any or
          all of the Collateral and the right to take possession of the
          Collateral, and for that purpose the Secured Party may enter any
          premises on which the Collateral or any part thereof may be situated
          and remove the same therefrom, so long as the same may be accomplished
          without a breach of the peace. The Secured Party may require Debtor to
          assemble the Collateral and make it available to the Secured Party at
          a place to be designated by the Secured Party which is reasonably
          convenient to the parties. Unless the Collateral is perishable or
          threatens to decline speedily in value or is of a type customarily
          sold on a recognized market, the Secured Party will send Debtor
          reasonable notice of the time and place of any public sale thereof or
          of the time after which any private sale or other disposition thereof
          is to be made. The requirement of sending reasonable notice shall be
          met if such notice is given to Debtor at least ten days before the
          time of the sale or disposition. Expenses of retaking, holding,
          preparing for sale, selling or the like shall include the Secured
          Party's reasonable fees and expenses (including, but not limited to,
          reasonable fees and expenses of legal counsel), and Debtor agrees to
          pay such expenses, plus interest thereon at the rate set forth in
          paragraph 3(c) hereof. Debtor shall remain liable for any deficiency
          hereunder or under the Note;

               (ii) Notify the account of debtors or obligors of any accounts,
          chattel paper, negotiable instruments or other evidences of
          indebtedness remitted by Debtor to the Secured Party as proceeds to
          pay the Secured Party directly;

               (iii) Demand, sue for, collect or make any compromise or
          settlement with reference to the Collateral as the Secured Party, in
          its sole discretion, chooses; and

               (iv) Remedy any default and may waive any default without waiving
          or being deemed to have waived any other prior or subsequent default.

     7.   Miscellaneous.
