<PAGE>

         This Warrant is one of a series of Warrants (the "Investor Warrants")
issued by the Company pursuant to the terms and conditions of a private
placement (the "Private Placement") of the Company's securities as described in
the Company's Subscription Agreement.

         1.       Exercise.
                  --------

                  (a)      This Warrant may be exercised at any time or from
time to time from and after the Original Issuance Date and before 5:00 p.m.,
Eastern Time, on May 12, 2009, on any business day, for the full number of
shares of Common Stock called for hereby, by surrendering it at the principal
office of the Company, at 3001 Bee Caves Road, Suite 250, Austin, Texas 78746,
with the subscription form duly executed, together with payment in an amount
equal to (a) the number of shares of Common Stock called for on the face of this
Warrant, as adjusted in accordance with the preceding paragraph of this Warrant
(without giving effect to any further adjustment herein) multiplied (b) by the
Purchase Price. Payment of this amount may be made at Holder's choosing either
(1) by payment in cash or by corporate check, payable to the order of the
Company, or (2) through a cashless exercise. At any time during the Exercise
Period, the Holder may, at its option, exercise this Warrant on a cashless basis
by exchanging this Warrant, in whole or in part (a "Warrant Exchange"), into the
number of shares of Common Stock determined in accordance with this Section 1(a)
by surrendering this Warrant at the principal office of the Company or at the
office of its stock transfer agent, accompanied by a notice stating such
Holder's intent to effect such exchange, the number of Warrant Shares to be
exchanged and the date on which the Holder requests that such Warrant Exchange
occur (the "Notice of Exchange"). The Warrant Exchange shall take place on the
date specified in the Notice of Exchange or, if later, the date the Notice of
Exchange is received by the Company (the "Exchange Date"). Certificates for
shares of Common Stock issuable upon such Warrant Exchange and, if applicable, a
new Warrant of like tenor evidencing the balance of the shares of Common Stock
remaining subject to this Warrant, shall be issued as of the Exchange Date and
delivered to the Holder within three (3) days following the Exchange Date. In
connection with any Warrant Exchange, this Warrant shall represent the right to
subscribe for and acquire the number of Warrant Shares equal to (i) the number
of Warrant Shares specified by the Holder in its Notice of Exchange (the "Total
Number") less (ii) the number of Warrant Shares equal to the quotient obtained
by dividing (A) the product of the Total Number and the existing Exercise Price
by (B) the Fair Market Value. "Fair Market Value" shall have the meaning set
forth in Section 1(b) below, except that for purposes hereof, the date of
exercise, as used in such Section III, shall mean the Exchange Date. This
Warrant may be exercised for less than the full number of shares of Common Stock
at the time called for hereby, except that the number of shares receivable upon
the exercise of this Warrant as a whole, and the sum payable upon the exercise
of this Warrant as a whole, shall be proportionately reduced. Upon a partial
exercise of this Warrant in accordance with the terms hereof, this Warrant shall
be surrendered, and a new Warrant of the same tenor and for the purchase of the
number of such shares not purchased upon such exercise shall be issued by the
Company to Holder without any charge therefor. A Warrant shall be deemed to have
been exercised immediately prior to the close of business on the date of its
surrender for exercise as provided above, and the person entitled to receive the
shares of Common Stock issuable upon such exercise shall be treated for all
purposes as the holder of such shares of record as of the close of business on
such date. Within two (2) business days after such date (the "Share Delivery
Date"), the Company shall issue and deliver to the person or persons entitled to
receive the same a certificate or certificates for the number of full shares of
Common Stock issuable upon such exercise, together with cash, in lieu of any

                                      -2-
<PAGE>

fraction of a share, equal to such fraction of the then Fair Market Value on the
date of exercise of one full share of Common Stock.

                  (b)      "Fair Market Value" shall mean, as of any date, (i)
if shares of the Common Stock are listed on a national securities exchange, the
average of the closing prices as reported for composite transactions during the
ten (10) consecutive trading days preceding the trading day immediately prior to
such date or, if no sale occurred on a trading day, then the mean between the
closing bid and asked prices on such exchange on such trading day; (ii) if
shares of the Common Stock are not so listed but are traded on the Nasdaq
SmallCap Market ("NSCM"), the average of the closing prices as reported on the
NSCM during the ten (10) consecutive trading days preceding the trading day
immediately prior to such date or, if no sale occurred on a trading day, then
the mean between the highest bid and lowest asked prices as of the close of
business on such trading day, as reported on the NSCM; or if applicable, the
Nasdaq National Market ("NNM"), or if not then included for quotation on the NNM
or NSCM, the average of the highest reported bid and lowest reported asked
prices as reported by the OTC Bulletin Board or the National Quotations Bureau,
as the case may be, or (iii) if the shares of the Common Stock are not then
publicly traded, the fair market price, not less than book value thereof, of the
Common Stock as determined in good faith by the independent members of the Board
of Directors of the Company (the "Board").

         2.       Shares Fully Paid; Payment of Taxes. All shares of Common
Stock issued upon the exercise of a Warrant shall be validly issued, fully paid
and non-assessable, and the Company shall pay all taxes and other governmental
charges (other than income taxes to the holder) that may be imposed in respect
of the issue or delivery thereof.

         3.       Transfer and Exchange. This Warrant and all rights hereunder
are transferable, in whole or in part, on the books of the Company maintained
for such purpose at its principal office referred to above by Holder in person
or by duly authorized attorney, upon surrender of this Warrant together with a
completed and executed assignment form in the form attached as Exhibit B,
payment of any necessary transfer tax or other governmental charge imposed upon
such transfer and an opinion of counsel reasonably acceptable the Company
stating that such transfer is exempt from the registration requirements of the
Securities Act of 1933, as amended (the "1933 Act"). Upon any partial transfer,
the Company will issue and deliver to Holder a new Warrant or Warrants with
respect to the shares of Common Stock not so transferred. Each taker and holder
of this Warrant, by taking or holding the same, consents and agrees that this
Warrant when endorsed in blank shall be deemed negotiable and that when this
Warrant shall have been so endorsed, the holder hereof may be treated by the
Company and all other persons dealing with this Warrant as the absolute owner
hereof for any purpose and as the person entitled to exercise the rights
represented hereby, or to the transfer hereof on the books of the Company, any
notice to the contrary notwithstanding; but until such transfer on such books,
the Company may treat the registered Holder hereof as the owner for all
purposes.

         This Warrant is exchangeable at such office for Warrants for the same
aggregate number of shares of Common Stock, each new Warrant to represent the
right to purchase such number of shares as the Holder shall designate at the
time of such exchange.

         4.       Anti-Dilution Provisions.
                  ------------------------

                  (a)      Adjustment for Dividends in Other Stock and Property
Reclassifications. In case at any time or from time to time the holders of the
Common Stock (or any shares of stock or other securities at the time receivable
upon the exercise of this Warrant) shall have received, or, on or after the
record date fixed for the determination of eligible shareholders, shall have
become entitled to receive, without payment therefor,

                           (i)      other or additional stock or other
securities or property (other than cash) by way of dividend,

                           (ii)     any cash or other property paid or payable
out of any source other than retained earnings (determined in accordance with
generally accepted accounting principles), or

                           (iii)    other or additional stock or other
securities or property (including cash) by way of stock-split, spin-off,
reclassification, combination of shares or similar corporate rearrangement,
(other than (x) additional shares of Common Stock or any other stock or
securities into which such Common Stock shall have been changed, (y) any other
stock or securities convertible into or exchangeable for such Common Stock or
such other stock or securities or (z) any Stock Purchase Rights, issued as a
stock dividend or stock-split, adjustments in respect of which shall be covered
by the terms of Sections 4(c), 4(d), 4(e) or 6, then and in each such case
Holder, upon the exercise hereof as provided in Section 1, shall be entitled to
receive the amount of stock and other securities and property (including cash in
the cases referred to in clauses (2) and (3) above) which such Holder would hold
on the date of such exercise if on the Original Issuance Date Holder had been
the holder of record of the number of shares of Common Stock called for on the
face of this Warrant, as adjusted in accordance with the first paragraph of this
Warrant, and had thereafter, during the period from the Original Issuance Date
to and including the date of such exercise, retained such shares and/or all
other or additional stock and other securities and property (including cash in
the cases referred to in clause (2) and (3) above) receivable by it as aforesaid
during such period, giving effect to all adjustments called for during such
period by Section 4(a) and Section 4(b).

                  (b)      Adjustment for Reorganization, Consolidation and
Merger. In case of any reorganization of the Company (or any other corporation
the stock or other securities of which are at the time receivable on the
exercise of this Warrant) after the Original Issuance Date, or in case, after
such date, the Company (or any such other corporation) shall consolidate with or
merge into another corporation or entity or convey all or substantially all its
assets to another corporation or entity, then and in each such case Holder, upon
the exercise hereof as provided in Section 1 at any time after the consummation
of such reorganization, consolidation, merger or conveyance, shall be entitled
to receive, in lieu of the stock or other securities and property receivable
upon the exercise of this Warrant prior to such consummation, the stock or other
securities or property to which such Holder would have been entitled upon such
consummation if Holder had exercised this Warrant immediately prior thereto, all
subject to further adjustment as provided in Sections 4(a), 4(b), 4(c) and 4(d);
in each such case, the terms of this Warrant shall be applicable to the shares
of stock or other securities or property receivable upon the exercise of this
Warrant after such consummation.

                                      -4-
<PAGE>

                  (c)      Adjustment for Certain Dividends and Distributions.
If the Company at any time or from time to time makes, or fixes a record date
for the determination of holders of Common Stock entitled to receive, a dividend
or other distribution payable in additional shares of Common Stock, then and in
each such event:

                           (i)      the Purchase Price then in effect shall be
decreased as of the time of such issuance or, in the event such record date is
fixed, as of the close of business on such record date, by multiplying the
Purchase Price then in effect by a fraction (A) the numerator of which is the
total number of shares of Common Stock issued and outstanding immediately prior
to the time of such issuance or the close of business on such record date, and
(B) the denominator of which shall be the total number of shares of Common Stock
issued and outstanding immediately prior to the time of such issuance or the
close of business on such record date as the case may be, plus the number of
shares of Common Stock issuable in payment of such dividend or distribution;
provided, however, that if such record date is fixed and such dividend is not
fully paid or if such distribution is not fully made on the date fixed therefor,
the Purchase Price shall be recomputed accordingly as of the close of business
on such record date, and thereafter the Purchase Price shall be adjusted
pursuant to this Section 4(c) as of the time of actual payment of such dividends
or distributions; and

                           (ii)     the number of shares of Common Stock
theretofore receivable upon the exercise of this Warrant shall be increased, as
of the time of such issuance or, in the event such record date is fixed, as of
the close of business on such record date, in inverse proportion to the decrease
in the Purchase Price.

                  (d)      Stock Split and Reverse Stock Split. If the Company
at any time or from time to time effects a reverse stock split or subdivision of
the outstanding Common Stock, the Purchase Price then in effect immediately
before that stock split or subdivision shall be proportionately decreased and
the number of shares of Common Stock theretofore receivable upon the exercise of
this Warrant shall be proportionately increased. If the Company at any time or
from time to time effects a reverse stock split or combines the outstanding
shares of Common Stock into a smaller number of shares, the Purchase Price then
in effect immediately before that reverse stock split or combination shall be
proportionately increased and the number of shares of Common Stock theretofore
receivable upon the exercise of this Warrant shall be proportionately decreased.
Each adjustment under this Section 4(d) shall become effective at the close of
business on the date the stock split, subdivision, reverse stock split or
combination becomes effective.

                  (e)      No Impairment. The Company will not, by amendment of
its Amended and Restated Articles of Incorporation or through any
reorganization, transfer of assets, consolidation, merger, dissolution, issue or
sale of securities or any other voluntary action, avoid or seek to avoid the
observance or performance of any of the terms to be observed or performed
hereunder by the Company but will at all times in good faith assist in the
carrying out of all the provisions of this Section 4 and in the taking of all
such action as may be necessary or appropriate in order to protect the rights of
the Holders of the Warrants against impairment.

                  (f)      Certificate as to Adjustments. Upon the occurrence of
each adjustment or readjustment of the Conversion Price pursuant to this Section
4, the Company at its expense shall promptly compute such adjustment or

                                      -5-
<PAGE>

readjustment in accordance with the terms hereof and furnish to each holder of a
Warrant a certificate setting forth such adjustment or readjustment and showing
in detail the facts upon which such adjustment or readjustment is based. The
Company shall, upon the written request at any time of any holder of a Warrant,
furnish or cause to be furnished to such holder a like certificate setting forth
(i) such adjustments and readjustments, (ii) Purchase Price at the time in
effect, and (iii) the number of shares of Common Stock and the amount, if any,
of other property which at the time would be received upon the exercise of the
Warrant.

         5.       Notices of Record Date. In case:
                  ----------------------

                  (a)      the Company shall take a record of the holders of its
Common Stock (or other stock or securities at the time receivable upon the
exercise of the Warrants) for the purpose of entitling them to receive any
dividend or other distribution, or any right to subscribe for or purchase any
shares of stock of any class or any other securities, or to receive any other
right, or

                  (b)      of any capital reorganization of the Company, any
reclassification of the capital stock of the Company, any consolidation or
merger of the Company with or into another corporation, or any conveyance of all
or substantially all of the assets of the Company to another corporation, or

                  (c)      of any voluntary dissolution, liquidation or
winding-up of the Company,

then, and in each such case, the Company will mail or cause to be mailed to each
holder of a Warrant at the time outstanding a notice specifying, as the case may
be, (a) the date on which a record is to be taken for the purpose of such
dividend, distribution or right, and stating the amount and character of such
dividend, distribution or right, or (b) the date on which such reorganization,
reclassification, consolidation, merger, conveyance, dissolution, liquidation or
winding-up is expected to take place, and the time, if any is to be fixed, as of
which the holders of record of Common Stock (or such stock or securities at the
time receivable upon the exercise of the Warrants) shall be entitled to exchange
their shares of Common Stock (or such other stock or securities) for securities
or other property deliverable upon such reorganization, reclassification,
consolidation, merger, conveyance, dissolution, liquidation or winding-up, such
notice shall be mailed at least twenty (20) days prior to the date therein
specified.

         6.       Loss or Mutilation. Upon receipt by the Company of evidence
satisfactory to it (in the exercise of reasonable discretion) of the ownership
of and the loss, theft, destruction or mutilation of any Warrant and (in the
case of loss, theft or destruction) of indemnity satisfactory to it (in the
exercise of reasonable discretion), and (in the case of mutilation) upon
surrender and cancellation thereof, the Company will execute and deliver in lieu
thereof a new Warrant of like tenor.

         7.       Reservation of Common Stock. The Company shall at all times
reserve and keep available for issue upon the exercise of Warrants such number
of its authorized but unissued shares of Common Stock as will be sufficient to
permit the exercise in full of all outstanding Warrants.

                                      -6-
<PAGE>

         8.       Registration Rights. The Holder of this Warrant and the Common
Stock issuable upon the exercise hereof is entitled to have such Common Stock
registered under the 1933 Act in accordance with the registration rights
provisions contained in a Subscription Agreement between the Company and the
initial Holder of this Warrant, of even date herewith.

         9.       Redemption of Warrants.
                  ----------------------

                  (a)      Commencing on the date sixty (60) days from the final
closing of the Private Placement, on not less than thirty (30) days' written
notice (the "Redemption Notice") to all registered holders of the Investor
Warrants, the Investor Warrants may be redeemed, at the option of the Company,
in whole and not in part, at a redemption price of $0.01 per Investor Warrants
(the "Redemption Price"), provided either (i) (A) the average closing bid price
of the Company's Common Stock shall equal or exceed $3.00 per share for the
thirty (30) consecutive trading days (the "Target Price"), subject to
adjustments as set forth in Section 9(f) hereafter, (B) the Common Stock is
traded on a national securities exchange or quoted on the NSCM or the NNSM; and
(C) the average trading volume of the Common Stock during such thirty-day period
is equal to or greater than 100,000 shares per day; or (ii) (A) a registration
statement covering the sale of the Company's securities for the raising of
capital in an amount exceeding $10,000,000 is filed under the Securities Act of
1933, as amended (the "Act") and (B) has been declared effective by the
Securities and Exchange Commission (the "Redemption Date").

                  (b)      If the conditions set forth in Section 9(a) are met,
and the Company desires to exercise its right to redeem the Investor Warrants,
it shall mail a Redemption Notice to each of the registered Holders, first class
mail, postage prepaid, not later than the thirtieth (30th) day before the date
fixed for redemption.

                  (c)      The Redemption Notice shall specify (i) the
Redemption Price, (ii) the Redemption Date, (iii) the place where the Investor
Warrant certificates shall be delivered and the redemption price paid, and (iv)
that the right to exercise this Warrant shall terminate at 5:00 p.m. (New York
time) on the business day immediately preceding the Redemption Date. No failure
to mail such notice nor any defect therein or in the mailing thereof shall
affect the validity of the proceedings for such redemption except as to a Holder
(a) to whom notice was not mailed or (b) whose notice was defective. An
affidavit of the Secretary or an Assistant Secretary of the Company that the
Redemption Notice has been mailed shall, in the absence of fraud, be prima facie
evidence of the facts stated therein.

                  (d)      Any right to exercise this Warrant shall terminate at
5:00 p.m. (New York time) on the business day immediately preceding the
Redemption Date. On and after the Redemption Date, the Holder of this Warrant
shall have no further rights except to receive, upon surrender of this Warrant,
the Redemption Price.

                  (e)      From and after the Redemption Date, the Company
shall, at the place specified in the Redemption Notice, upon presentation and
surrender to the Company by or on behalf of the Holder thereof of one or more
Investor Warrant certificates evidencing Investor Warrants to be redeemed,
deliver, or cause to be delivered to or upon the written order of such holder a
sum in cash equal to the Redemption Price of each such Investor Warrant. From
and after the Redemption Date and upon the deposit or setting aside by the
Company of a sum sufficient to redeem all the Investor Warrants called for

                                      -7-
<PAGE>

redemption, such Investor Warrants shall expire and become void and all rights
hereunder, except the right to receive payment of the Redemption Price, shall
cease.

                  (f)      If the shares of Common Stock are subdivided or
combined into a greater or smaller number of shares of Common stock, the Target
Price shall be proportionately adjusted by the ratio which the total number of
shares of Common Stock outstanding immediately prior to such event bears to the
total number of shares of Common Stock to be outstanding immediately after such
event.

         10.      Notices. All notices and other communications from the Company
to the Holder of this Warrant shall be mailed by first class, registered or
certified mail, postage prepaid, to the address furnished to the Company in
writing by the last holder of this Warrant who shall have furnished an address
to the Company in writing.

         11.      Change; Modifications; Waiver. The terms of this Warrant may
be amended, waived or modified solely by agreement of the Company and holders of
Investor Warrants owning greater than a majority of the shares of Common Stock
issuable upon the exercise of all of the then outstanding Investor Warrants.

         12.      Headings. The headings in this Warrant are for purposes of
convenience in reference only, and shall not be deemed to constitute a part
hereof.

         13.      Law Governing. This Agreement shall be governed by and
construed in accordance with the internal laws of the State of New York without
regard to the conflicts of laws principles thereof. The parties hereto hereby
irrevocably agree that any suit or proceeding arising directly and/or indirectly
pursuant to or under this Agreement, shall be brought solely in a federal or
state court located in the City, County and State of New York. By its execution
hereof, the parties hereby covenant and irrevocably submit to the in personam
jurisdiction of the federal and state courts located in the City, County and
State of New York and agree that any process in any such action may be served
upon any of them personally, or by certified mail or registered mail upon them
or their agent, return receipt requested, with the same full force and effect as
if personally served upon them in New York City. The parties hereto waive any
claim that any such jurisdiction is not a convenient forum for any such suit or
proceeding and any defense or lack of in personam jurisdiction with respect
thereto. In the event of any such action or proceeding, the party prevailing
therein shall be entitled to payment from the other party hereto of its
reasonable counsel fees and disbursements in an amount judicially determined.
