to the provisions and upon the terms and conditions set forth of this Warrant.

ARTICLE 1.  EXERCISE
            --------

     1.1  Method of Exercise.  Holder may exercise this Warrant by delivering
          ------------------
this Warrant and a fully executed Notice of Exercise in substantially the form
attached as Appendix I to the principal office of' the Company, but such
exercise shall not occur prior to May 1, 1998.  Unless Holder is exercising the
conversion right set forth in Section 1.2. Holder shall also deliver to the
Company a check for the aggregate Warrant Price for the Shares being purchased.

     1.2  Conversion Right.  In lieu of exercising this Warrant as specified in
          ----------------
Section 1.1, Holder may from time to time convert this Warrant, in whole or in
part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares or other securities, otherwise issuable upon exercise
of this Warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share.  The fair market value of the Shares shall be
determined pursuant to Section 1.5.

     1.3  Omitted.
          -------

     1.4  Omitted.
          -------

     1.5  Fair Market Value.  If the Shares are traded regularly in a public
          -----------------
market, the fair market value of the Shares shall be the closing price of the
Shares (or the closing price of the


Company's stock into which the Shares are convertible) reported for the business
day immediately before Holder delivers its Notice of Exercise to the Company. If
tile Shares are not regularly traded in a public market, the Board of Directors
of the Company shall determine fair market value in its reasonable good faith
judgment. The foregoing notwithstanding, if Holder advises the Board of
Directors in writing that Holder disagrees with such determination, then the
Company and Holder shall promptly agree upon a reputable investment banking firm
to undertake such valuation. If tile valuation of such investment banking firm
is greater than that determined by the Board of Directors, then all fees and
expenses of such investment banking firm shall be paid by the Company. In all
other circumstances, such fees and expenses shall be paid by Holder.

     1.6  Delivery of Certificate and New Warrant.  Promptly after Holder
          ---------------------------------------
exercises or converts this Warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this Warrant has not been fully
exercised or converted and has not expired, a new Warrant representing the
Shares not so acquired.

     1.7  Replacement of Warrants.  On receipt of evidence reasonable
          -----------------------
satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, or surrender and cancellation of this Warrant,
the Company at its expense shall execute and deliver, in lieu of this Warrant, a
new warrant of like tenor.

     1.8  Repurchase on Sale, Merger, or Consolidation of the Company.
          -----------------------------------------------------------

          1.8.1.  "Acquisition".  For the purpose of this Warrant, "Acquisition"
                   -----------
means any sale, license, or other disposition of all or substantially all of the
assets (including intellectual property) of the Company or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

          1.8.2.  Assumption of Warrant.  If upon the closing of any Acquisition
                  ---------------------
the successor entity assumes the obligations of this Warrant, then this Warrant
shall be exercisable for the same securities, cash, and property as would be
payable for the Shares issuable upon exercise of the unexercised portion of this
Warrant as if such Shares were outstanding on the record date for the
Acquisition and subsequent closing.  The Warrant Price shall be adjusted
accordingly.  The Company shall use reasonable efforts to cause the surviving
corporation to assume the obligations of this Warrant.

          1.8.3.  Nonassumption.  If upon the closing of any Acquisition the
                  -------------
successor entity does not assume the obligations of this Warrant and Holder has
not otherwise exercised this Warrant in full, then the unexercised portion of
this Warrant shall be deemed to have been automatically converted pursuant to
Section 1.2 and thereafter Holder shall participate in the Acquisition oil the
same terms as other holders of the same class of securities of the Company.

     1.9  Adjustment in Underlying Preferred Stock Price and Exercise Price.  If
          -----------------------------------------------------------------
on or before February 28, 1998, (i) the Company provides Holder with reasonably
satisfactory written

                                       2


evidence of receipt by Company of signed, definitive term sheets for a minimum
of $2,000,000 in new equity from investors reasonably acceptable to Holder
("Investors"), and (ii) on or before April 30, 1998 the Company sells and issues
to Investors preferred stock and/or securities convertible into preferred stock
with aggregate gross proceeds to the Company of at least $2,000,000 in cash,
this Warrant shall concurrent with the issuance of such securities automatically
be adjusted to instead be exercisable for shares of the same series and class of
preferred stock and bearing the same rights, preferences, and privileges, of
such shares of stock with the Warrant Price hereunder adjusted to equal the per
share purchase price of such stock, and the number of such shares subject to
this Warrant adjusted to equal (i) Twenty-five Thousand Dollars ($25,000),
divided by (ii) such modified per share Warrant Price.

ARTICLE 2.  ADJUSTMENTS TO THE SHARES
            -------------------------

     2.1  Stock Dividends, Splits, Etc.  If the Company declares or pays a
          ----------------------------
dividend on its common stock payable in common stock, or other securities,
subdivides the outstanding common stock into a greater amount of common stock,
then upon exercise of this Warrant, for each Share acquired, Holder shall
receive, without cost to Holder, the total number and kind of securities to
Holder would have been entitled had Holder owned the Shares of record as of the
date the dividend or subdivision occurred.

     2.2  Reclassification, Exchange or Substitution.  Subject to Section 1.8,
          ------------------------------------------
upon any reclassification, exchange, substitution, or other event that results
in a change of the number and/or class of the securities issuable upon exercise
or conversion of this Warrant, Holder shall be entitled to receive, upon
exercise or conversion of this Warrant, the number and kind of securities and
property that Holder would have received for the Shares if this Warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event.  Such an event shall include any automatic conversion of the
outstanding or issuable securities of the Company of the same class or series as
the Shares to common stock pursuant to the terms of the Company's Articles of
Incorporation upon the closing of a registered public offering, of the Company's
common stock.  The Company or its successor shall promptly, issue to Holder a
new Warrant for such new securities or other property.  The new Warrant shall
provide for adjustments which shall be as nearly equivalent as may be
practicable to the adjustments provided for in this Article 2 including, without
limitations adjustments to the Warrant Price and to the number of securities or
property issuable upon exercise of the new Warrant.  The provisions of this
Section 2.2 shall similarly apply to successive reclassifications, exchanges,
substitutions, or other events.

     2.3  Adjustments for Combinations, Etc.  Except for the stock split, and
          ---------------------------------
related amendment to the Company's Articles of Incorporation contemplated by the
amendment to the Company's Articles of Incorporation approved by the Company's
Board of Directors at its meeting of December 16, 1997, if the Outstanding
Shares are Subdivided (by stock split or otherwise) into a greater number of
Shares then the number of Shares subject to purchase hereunder shall
automatically increase proportionally, and the Warrant Price per Share shall
automatically decrease proportionately, with the increase in the number of
Shares.  If the outstanding Shares are decreased (by reverse stock split or
otherwise) into a lesser number of shares then the number of Shares subject to
purchase hereunder shall automatically decrease

                                       3


proportionately, and the Warrant Price per Share shall automatically increase
proportionately, with the decrease in the number of Shares.

     2.4  Adjustments for Diluting Issuances.  The Shares will have the exact
          ----------------------------------
same anti-dilution protection under the Company's Articles of Incorporation as
all other Shares of the same class and series.

     2.5  No Impairment.  The Company shall not, by amendment of its Articles of
          -------------
Incorporation or through a 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 under this Warrant by the Company, but shall at all times
in good faith assist in carrying all the provisions of this Article 2 and in
taking all such action as may be necessary or appropriate to protect Holder's
rights under this Article against impairment.  If the Company takes any action
affecting the Shares or its common stock other than as described above that
adversely affects Holder's rights under this Warrant, the Warrant Price shall be
adjusted downward and the number of Shares issuable upon exercise of this
Warrant shall be adjusted upward in such a manner that the aggregate Warrant
Price of this Warrant is unchanged.

     2.6  Certificate as to Adjustments.  Upon each adjustment of the Warrant
          -----------------------------
Price the Company, at its expense shall promptly compute such adjustment and
furnish Holder with a certificate of its Chief Financial Officer setting forth
such adjustment and the facts upon which such adjustment is based.  The Company
shall, upon written request, furnish Holder a certificate setting forth the
Warrant Price in effect upon the date thereof and the series of adjustments
leading to such Warrant Price.
