1.    WARRANT.

      THIS CERTIFIES THAT, in consideration of $10.00 and other good and
valuable consideration, duly paid by or on behalf of TCA Investments, Inc. (the

thereafter, to subscribe for, purchase and receive, in whole or in part, up to
Five Hundred Thousand (500,000) shares of Common Stock of the Company, $0.001

banking institutions are authorized by law to close, then this Warrant may be
exercised on the next succeeding day which is not such a day in accordance with
the terms herein. During the period ending on the Expiration Date, the Company
agrees not to take any action that would terminate the Warrant. This Warrant is
exercisable at $1.13 (representing 110% of the closing bid price of the Common

provided, however, that upon the occurrence of any of the events specified in
Section 6 hereof, the rights granted by this Warrant, including the number of
shares of Common Stock to be received upon such exercise, shall be adjusted as
therein specified. The term "Exercise Price" shall mean the initial exercise
price or the adjusted exercise price, depending on the context, of a share of
Common Stock. The term "Securities" shall mean the shares of Common Stock
issuable upon exercise of this Warrant.

2.    EXERCISE.

      2.1 EXERCISE FORM. In order to exercise this Warrant, the exercise form
attached hereto must be duly executed and completed and delivered to the Company
on or before 5:00 p.m. Pacific Time on any business day on or prior to the
Expiration Date, together with the surrender of this Warrant and payment of the
Exercise Price for the Securities being purchased or delivery to the Company of

                                     Exh-12
<PAGE>
defined in Section 2.3 hereof). If the subscription rights represented hereby
shall not be exercised at or before 5:00 p.m., Pacific Time, on the Expiration
Date, this Warrant shall become and be void without further force or effect, and
all rights represented hereby shall cease and expire.

      2.2 LEGEND. Each certificate for Securities purchased under this Warrant
shall bear a legend as follows, unless such Securities have been registered
under the Securities Act of 1933, as amended ("Act"):

      "The securities represented by this certificate have not been registered
      under the Securities Act of 1933, as amended ("Act") or applicable state
      law. The securities may not be offered for sale, sold or otherwise
      transferred except pursuant to an effective registration statement under
      the Act or applicable state securities laws, or pursuant to an opinion of
      counsel satisfactory to the Company stating that an exemption from such
      registration is available for such sale and transfer."

      2.3   EXERCISE RIGHT.

                        2.3.1 EXERCISE IN FULL. The holder of this Warrant may
               exercise it in full by surrendering this Warrant, with the form
               of subscription at the end hereof duly executed by such holder,
               to the Company at its principal office. The surrendered Warrant
               shall be accompanied by payment, (a) in cash or by certified or
               official bank check payable to the order of the Company, in the
               amount obtained by multiplying the number of shares of Common
               Stock subject to this Warrant by the Exercise Price; or (b) by
               cashless exercise using the following formula ("Cashless
               Conversion"):

                                               X = Y (A-B) / A

                  Where: X = the number of shares of Common Stock to be issued
                  to the holder (not to exceed the number of shares set forth on
                  the cover page of this Warrant Agreement, as adjusted pursuant
                  to the provisions of Section 6 of this Warrant Agreement).

                  Y = the number of shares of Common Stock for which the Warrant
                  is being exercised.

                  A = the "Market Price" of one share of Common Stock (for
                  purposes of this Section), shall be defined as the closing bid
                  price of the Common Stock on the business day immediately
                  prior to the date of exercise of this Warrant (the "Closing
                  Bid Price"), as reported by the National Association of
                  Securities Dealers Automated Quotation System ("NASDAQ"), or
                  if the Common Stock is not traded on NASDAQ, the Closing Bid
                  Price in the over-the-counter market; provided, however, that
                  if the Common Stock is listed on a stock exchange, the Market
                  Price shall be the Closing Bid Price on such exchange; and,
                  provided further, that if the Common Stock is not quoted or
                  listed by any organization, the fair value of the Common
                  Stock, as reasonably determined by the Board of Directors of
                  the Company, whose determination shall be conclusive, shall be
                  used).

                  B = the Exercise Price of $1.13/share.

                        2.3.2 PARTIAL EXERCISE. This Warrant may be exercised in
               part by surrender of this Warrant in the manner and at the place
               provided in this Section 2.3 for the amount obtained by
               multiplying (a) the number of shares of Common Stock the holder
               of this Warrant chooses to purchase as shall be designated by the
               holder in the subscription at the end hereof by (b) the Exercise
               Price. On any such partial exercise, subject to the provisions of
               Section 2 hereof, the Company at its expense will forthwith issue
               and deliver to or upon the order of the holder hereof a new
               Warrant or Warrants of like tenor, in the name of the holder
               hereof or as such holder may request, calling in the aggregate on
               the face or faces thereof for the number of shares of Common
               Stock remaining subject to this Warrant after the exercise
               contemplated herein.

                        2.3.3 COMPANY ACKNOWLEDGMENT. The Company will, at the
               time of the exercise, exchange or transfer of this Warrant, upon
               the request of the holder hereof acknowledge in writing its
               continuing obligation to afford to such holder or transferee any
               rights (including, without limitation, any right to registration
               of the Shares as set forth in the Subscription Agreement
               incorporated by reference herein) to which such holder or
               transferee shall continue to be entitled after such exercise,
               exchange or transfer in accordance with the provisions of this
               Warrant, provided that if the holder of this Warrant shall fail
               to make any such request, such failure shall not affect the
               continuing obligation of the Company to afford to such holder or
               transferee any such rights.

                        2.3.4 DELIVERY OF STOCK CERTIFICATES, ETC., ON EXERCISE.
               As soon as practicable after the exercise of this Warrant in full
               or in part, and in any event within 10 days thereafter, the
               Company at its expense (including the payment by it of any
               applicable issue taxes) will cause to be issued in the name of
               and delivered to the holder hereof, or as such holder (upon
               payment by such holder of any applicable transfer taxes) may
               direct, a certificate or certificates for the number of fully
               paid and non-assessable Shares to which such holder shall be
               entitled on such exercise, and any fractional Share to which such
               holder would otherwise be entitled shall be eliminated pursuant
               to Section 6.2.

3.    TRANSFER.

      3.1 GENERAL RESTRICTIONS. The registered Holder of this Warrant, by its
acceptance hereof, agrees that it will not sell, transfer or assign or
hypothecate this Warrant to anyone except upon compliance with, or pursuant to
an opinion of counsel satisfactory to the Company stating that exemption from
registration under applicable federal and state securities laws is available for
such sale and transfer. In order to make any permitted assignment, after the
receipt of such opinion by the Company, the Holder must deliver to the Company
the assignment form attached hereto duly executed and completed, together with
this Warrant and payment of all transfer taxes, if any, payable in connection
therewith. The Company shall immediately transfer this Warrant on the books of
the Company and shall execute and deliver a new Warrant or Warrants of like
tenor to the appropriate assignee(s) expressly evidencing the right to purchase
the aggregate number of shares of Common Stock purchasable hereunder or such
portion of such number as shall be contemplated by any such assignment.

      3.2 RESTRICTIONS IMPOSED BY THE SECURITIES ACT. This Warrant and the
Securities underlying this Warrant shall not be transferred unless and until (i)
the Company has received the opinion of counsel for the Holder that such
securities may be sold pursuant to an exemption

                                     Exh-14
<PAGE>
from registration under the Act, and applicable state law, the availability of
which is established to the reasonable satisfaction of the Company, or (ii) a
registration statement relating to such Securities has been filed by the Company
and declared effective by the Securities and Exchange Commission ("SEC") and
compliance with applicable state law.

      4. NEW WARRANTS TO BE ISSUED.

      4.1 PARTIAL EXERCISE OR TRANSFER. Subject to the restrictions in Section 3
hereof, this Warrant may be exercised or assigned in whole or in part. In the
event of the exercise or assignment hereof in part only, upon surrender of this
Warrant for cancellation, together with the duly executed exercise or assignment
form and funds (or conversion equivalent) sufficient to pay any Exercise Price
and/or transfer tax, the Company shall cause to be delivered to the Holder
without charge a new Warrant of like tenor to this Warrant in the name of the
Holder evidencing the right of the Holder to purchase the aggregate number of
shares of Common Stock and Warrants purchasable hereunder as to which this
Warrant has not been exercised or assigned.

      4.2 LOST CERTIFICATE. Upon receipt by the Company of evidence satisfactory
to it of the loss, theft, destruction or mutilation of this Warrant and of
reasonably satisfactory indemnification, the Company shall execute and deliver a
new Warrant of like tenor and date. Any such new Warrant executed and delivered
as a result of such loss, theft, mutilation or destruction shall constitute a
substitute contractual obligation on the part of the Company.


      5. REGISTRATION RIGHTS.

            The Holders of this Warrant have been granted certain registration
rights as set forth in the Subscription Agreement between the Holder and Company
of even date herewith, and such Subscription Agreement shall be deemed to be
incorporated by reference herein. The Holders shall be entitled to exercise such
registration rights prior to the Exercise Date as set forth in the Subscription
Agreement.

      6. ADJUSTMENTS

      6.1 ADJUSTMENTS TO EXERCISE PRICE AND NUMBER OF SECURITIES. The Exercise
Price and the number of shares of Common Stock underlying this Warrant shall be
subject to adjustment from time to time as hereinafter set forth:

            6.1.1 STOCK DIVIDENDS - RECAPITALIZATION, RECLASSIFICATION,
SPLIT-UPS. If, after the date hereof, and subject to the provisions of Section
6.2 below, the number of outstanding shares of Common Stock is increased by a
stock dividend on the Common Stock payable in shares of Common Stock or by a
split-up, recapitalization or reclassification of shares of Common Stock or
other similar event, then, on the effective date thereof, the number of shares
of Common Stock issuable on exercise of this Warrant shall be increased in
proportion to such increase in outstanding shares.

            6.1.2 AGGREGATION OF SHARES. If after the date hereof, and subject
to the provisions of Section 6.2, the number of outstanding shares of Common
Stock is decreased by a consolidation, combination or reclassification of shares
of Common Stock or other similar event, then, upon the effective date thereof,
the number of shares of Common Stock issuable

                                     Exh-15
<PAGE>
on exercise of this Warrant shall be decreased in proportion to such decrease in
outstanding shares.

            6.1.3 ADJUSTMENTS IN EXERCISE PRICE. Whenever the number of shares
of Common Stock purchasable upon the exercise of this Warrant is adjusted, as
provided in this Section 6.1, the Exercise Price shall be adjusted (to the
nearest cent) by multiplying such Exercise Price immediately prior to such
adjustment by a fraction (x) the numerator of which shall be the number of
shares of Common Stock purchasable upon the exercise of this Warrant immediately
prior to such adjustment, and (y) the denominator of which shall be the number
of shares of Common Stock so purchasable immediately thereafter.

            6.1.4 REPLACEMENT OF SECURITIES UPON REORGANIZATION, ETC. In case of
any reclassification or reorganization of the outstanding shares of Common Stock
other than a change covered by Section 6.1.1 hereof or which solely affects the
par value of such shares of Common Stock, or in the case of any merger or
consolidation of the Company with or into another corporation (other than a
consolidation or merger in which the Company is the continuing corporation and
which does not result in any reclassification or reorganization of the
outstanding shares of Common Stock), or in the case of any sale or conveyance to
another corporation or entity of the property of the Company as an entirety or
substantially as an entirety in connection with which the Company is dissolved,
the Holder of this Warrant shall have the right thereafter (until the expiration
of the right of exercise of this Warrant) to receive upon the exercise hereof,
for the same aggregate Exercise Price payable hereunder immediately prior to
such event, the kind and amount of shares of stock or other securities or
property (including cash) receivable upon such reclassification, reorganization,
merger or consolidation, or upon a dissolution following any such sale or other
transfer, by a Holder of the number of shares of Common Stock of the Company
obtainable upon exercise of this Warrant immediately prior to such event; and if
any reclassification also results in a change in shares of Common Stock covered
by Sections 6.1.1 or 6.1.2, then such adjustment shall be made pursuant to
Sections 6.1.1, 6.1.2, 6.1.3 and this Section 6.1.4. The provisions of this
Section 6.1.4 shall similarly apply to successive reclassifications,
reorganizations, mergers or consolidations, sales or other transfers.

            6.1.5 CHANGES IN FORM OF WARRANT. This form of Warrant need not be
changed because of any change pursuant to this Section, and Warrants issued
after such change may state the same Exercise Price and the same number of
shares of Common Stock and Warrants as are stated in the Warrants initially
issued pursuant to this Agreement. The acceptance by any Holder of the issuance
of new Warrants reflecting a required or permissive change shall not be deemed
to waive any rights to a prior adjustment or the computation thereof.

      6.2 ELIMINATION OF FRACTIONAL INTERESTS. The Company shall not be required
to issue certificates representing fractions of shares of Common Stock upon the
exercise of this Warrant, nor shall it be required to issue scrip or pay cash in
lieu of any fractional interests, it being the intent of the parties that all
fractional interests shall be eliminated by rounding any fraction up to the
nearest whole number of shares of Common Stock or other securities, properties
or rights.

      7. RESERVATION AND LISTING. The Company shall at all times reserve and
keep available out of its authorized shares of Common Stock, solely for the
purpose of issuance upon exercise of this Warrant, such number of shares of
Common Stock or other securities, properties or rights as shall be issuable upon
the exercise thereof. The Company covenants and agrees that, upon exercise of
the Warrants and payment of the Exercise Price therefor, all shares of Common
Stock and other securities issuable upon such exercise shall be duly and

                                     Exh-16
<PAGE>
validly issued, fully paid and non-assessable and not subject to preemptive
rights of any stockholder. As long as the Warrants shall be outstanding, the
Company shall use its best efforts to cause all shares of Common Stock issuable
upon exercise of the Warrants to be listed (subject to official notice of
issuance) on all securities exchanges (or, if applicable on Nasdaq) on which the
Common Stock is then listed and/or quoted.

      8. CERTAIN NOTICE REQUIREMENTS.

      8.1 HOLDER'S RIGHT TO RECEIVE NOTICE. Nothing herein shall be construed as
conferring upon the Holders the right to vote or consent or to receive notice as
a stockholder for the election of directors or any other matter, or as having
any rights whatsoever as a stockholder of the Company. If, however, at any time
prior to the expiration of the Warrants and their exercise, any of the events
described in Section 8.2 shall occur, then, in one or more of said events, the
Company shall give written notice of such event at least fifteen days prior to
the date fixed as a record date or the date of closing the transfer books for
the determination of the stockholders entitled to such dividend, distribution,
conversion or exchange of securities or subscription rights, or entitled to vote
on such proposed dissolution, liquidation, winding up or sale. Such notice shall
specify such record date or the date of the closing of the transfer books, as
the case may be.

      8.2 EVENTS REQUIRING NOTICE. The Company shall be required to give the
notice described in this Section 8 upon one or more of the following events: (i)
if the Company shall take a record of the holders of its shares of Common Stock
for the purpose of entitling them to receive a dividend or distribution, or (ii)
the Company shall offer to all the holders of its Common Stock any additional
shares of capital stock of the Company or securities convertible into or
exchangeable for shares of capital stock of the Company, or any option, right or
warrant to subscribe therefor, or (iii) a merger or reorganization in which the
Company is not the surviving party, or (iv) a dissolution, liquidation or
winding up of the Company (other than in connection with a consolidation or
merger) or a sale of all or substantially all of its property, assets and
business shall be proposed.

      8.3 NOTICE OF CHANGE IN EXERCISE PRICE. The Company shall, promptly after
an event requiring a change in the Exercise Price pursuant to Section 6 hereof,
send notice to the Holders of such event and change ("Price Notice"). The Price
Notice shall describe the event causing the change and the method of calculating
same and shall be certified as being true and accurate by the Company's
President and Chief Financial Officer.

      8.4 TRANSMITTAL OF NOTICES. All notices, requests, consents and other
communications under this Warrant shall be in writing and shall be deemed to
have been duly made on the date of delivery if delivered personally or sent by
overnight courier, with acknowledgment of receipt by the party to which notice
is given, or on the third day after mailing if mailed to the party to whom
notice is to be given, by registered or certified mail, return receipt
requested, postage prepaid and properly addressed as follows: (i) if to the
registered Holder of this Warrant, to the address of such Holder as shown on the
