                          COMMON STOCK PURCHASE WARRANT
                          -----------------------------

No. 28                                                 Void after March 29, 2010

      THIS CERTIFIES THAT, for value received, Excipio Group, S.A. (the
"Holder") is entitled to subscribe for and purchase 570,000 shares (as such
number of shares shall be adjusted pursuant to Section 3 hereof, thus adjusting
the per share Exercise Price) of the fully paid and nonassessable Common Stock,
$0.001 par value (the "Shares"), of TechAlt, Inc., a Nevada corporation (the
"Company"), at the exercise price of $1.00 per share (the "Exercise Price"),
subject to the provisions and upon the terms and conditions hereinafter set
forth.

      1. Method of Exercise; Payment.

      (a) Cash Exercise. The purchase rights represented by this Warrant may be
exercised by the Holder, in whole or in part, by the surrender of this Warrant
(with the notice of exercise form attached hereto as Exhibit A duly executed) at
the principal office of the Company, and by the payment to the Company, by
certified, cashier's or other check acceptable to the Company or by wire
transfer to an account designated by the Company, of an amount equal to the
aggregate Exercise Price of the Shares being purchased.

      (b) Cashless Exercise. In lieu of exercising this Warrant, the Holder may
elect to receive Shares equal to the value of this Warrant (or the portion
thereof being canceled) by surrender of this Warrant at the principal office of
the Company together with notice of such election, in which event the Company
shall issue to the Holder a number of Shares computed using the following
formula:

<PAGE>

                  X = Y (A-B)
                      -------
                          A

      Where X = the number of the Shares to be issued to the Holder.

      Y = the number of the Shares purchasable under this Warrant.

      A = the fair market value of one Share on the date of determination.

      B = the per share Exercise Price (as adjusted to the date of such
          calculation).

      (c) Fair Market Value. For purposes of this Section 1, the per share fair
market value of the Shares shall mean:

            (i) If the Company's Common Stock is publicly traded, the per share
      fair market value of the Shares shall be the average of the closing prices
      of the Common Stock as quoted on the Over The Counter Bulletin Board or
      the principal exchange on which the Common Stock is listed, or if not so
      listed then the fair market value shall be the average of the closing bid
      prices of the Common Stock as published in The Wall Street Journal, in
      each case for the fifteen (15) trading days ending five (5) trading days
      prior to the date of determination of fair market value;

            (ii) If the Company's Common Stock is not so publicly traded, the
      per share fair market value of the Shares shall be such fair market value
      as is determined in good faith by the Board of Directors of the Company
      after taking into consideration factors it deems appropriate, including,
      without limitation, recent sale and offer prices of the capital stock of
      the Company in private transactions negotiated at arm's length.

      (d) Stock Certificates. In the event of any exercise of the rights
represented by this Warrant, certificates for the Shares so purchased shall be
delivered to the Holder within a reasonable time and, unless this Warrant has
been fully exercised or has expired, a new Warrant representing the shares with
respect to which this Warrant shall not have been exercised shall also be issued
to the Holder within such time.

      (e) Limitations on Exercise. The Company shall not effect the exercise of
this Warrant, and no Person (as defined below) who is a holder of this Warrant
shall have the right to exercise this Warrant, to the extent that after giving
effect to such exercise, such Person (together with such Person's affiliates)
would beneficially own in excess of 9.99% of the shares of the Common Stock
outstanding immediately after giving effect to such exercise. For purposes of
the foregoing sentence, the aggregate number of shares of Common Stock
beneficially owned by such Person and its affiliates shall include the number of
shares of Common Stock issuable upon exercise of this Warrant with respect to
which the determination of such sentence is being made, but shall exclude shares
of Common Stock which would be issuable upon (i) exercise of the remaining,
unexercised portion of this Warrant beneficially owned by such Person and its
affiliates and (ii) exercise or conversion of the unexercised or unconverted
portion of any other securities of the Company beneficially owned by such Person
and its affiliates (including, without limitation, any convertible notes or
convertible preferred stock or warrants) subject to a limitation on conversion
or exercise analogous to the limitation contained herein. Except as set forth in
the preceding sentence, for purposes of this paragraph, beneficial ownership
shall be calculated in accordance with Section 13(d) of the Securities Exchange
Act of 1934, as amended. For purposes of this Warrant, in determining the number
of outstanding shares of Common Stock the Holder may rely on the number of
outstanding shares of Common Stock as reflected in (1) the Company's most recent
Form 10-Q or 10-QSB, as applicable, Form 10-K or 10-KSB, as applicable, or other
public filing with the Securities and Exchange Commission, as the case may be,
(2) a more recent public announcement by the Company or (3) any other notice by
the Company or its Transfer Agent setting forth the number of shares of Common
Stock outstanding. For any reason at any time, upon the written or oral request
of the Holder, the Company shall within one Business Day confirm in writing to
the Holder the number of shares of Common Stock then outstanding.

      2. Stock Fully Paid; Reservation of Shares. All of the Shares issuable
upon the exercise of the rights represented by this Warrant will, upon issuance
and receipt of the Exercise Price therefor, be fully paid and nonassessable, and
free from all taxes, liens and charges with respect to the issue thereof. During
the period within which the rights represented by this Warrant may be exercised,
the Company shall at all times have authorized and reserved for issuance
sufficient shares of its Common Stock to provide for the exercise of the rights
represented by this Warrant.

      3. Adjustments. Subject to the provisions of Section 11 hereof, the number
and kind of securities purchasable upon the exercise of this Warrant and the
Exercise Price therefor shall be subject to adjustment from time to time upon
the occurrence of certain events, as follows:

      (a) Reclassification. In the case of any reclassification or change of
securities of the class issuable upon exercise of this Warrant (other than a
change in par value, or from par value to no par value, or from no par value to
par value, or as a result of a subdivision or combination), or in case of any
merger of the Company with or into another corporation (other than a merger with
another corporation in which the Company is the acquiring and the surviving
corporation and which does not result in any reclassification or change of
outstanding securities issuable upon exercise of this Warrant), or in case of
any sale of all or substantially all of the assets of the Company, the Company,
or such successor or purchasing corporation, as the case may be, shall duly
execute and deliver to the holder of this Warrant a new Warrant (in form and
substance reasonably satisfactory to the holder of this Warrant), or the Company
shall make appropriate provision without the issuance of a new Warrant, so that
the holder of this Warrant shall have the right to receive, at a total purchase
price not to exceed that payable upon the exercise of the unexercised portion of
this Warrant, and in lieu of the shares of Common Stock theretofore issuable
upon exercise of this Warrant, (i) the kind and amount of shares of stock, other
securities, money and property receivable upon such reclassification, change,
merger or sale by a holder of the number of shares of Common Stock then
purchasable under this Warrant, or (ii) in the case of such a merger or sale in
which the consideration paid consists all or in part of assets other than
securities of the successor or purchasing corporation, at the option of the
Holder of this Warrant, the securities of the successor or purchasing
corporation having a value at the time of the transaction equivalent to the fair
market value of the Common Stock at the time of the transaction. The provisions
of this subparagraph (a) shall similarly apply to successive reclassifications,
changes, mergers and transfers.


                                       3

      (b) Stock Splits, Dividends and Combinations. In the event that the
Company shall at any time subdivide the outstanding shares of Common Stock or
shall issue a stock dividend on its outstanding shares of Common Stock the
number of Shares issuable upon exercise of this Warrant immediately prior to
such subdivision or to the issuance of such stock dividend shall be
proportionately increased, and the Exercise Price shall be proportionately
decreased, and in the event that the Company shall at any time combine the
outstanding shares of Common Stock the number of Shares issuable upon exercise
of this Warrant immediately prior to such combination shall be proportionately
decreased, and the Exercise Price shall be proportionately increased, effective
at the close of business on the date of such subdivision, stock dividend or
combination, as the case may be.

      4. Notice of Adjustments. Whenever the number of Shares purchasable
hereunder or the Exercise Price thereof shall be adjusted pursuant to Section 3
hereof, the Company shall provide notice to the Holder setting forth, in
reasonable detail, the event requiring the adjustment, the amount of the
adjustment, the method by which such adjustment was calculated, and the number
and class of shares which may be purchased thereafter and the Exercise Price
therefor after giving effect to such adjustment.

      5. Fractional Shares. This Warrant may not be exercised for fractional
shares. In lieu of fractional shares the Company shall make a cash payment
therefor based upon the Exercise Price then in effect and the fair market value
of the shares then obtaining (calculated in accordance with Section 1(c) hereof
as if the shares were the Shares referred to in such Section).

      6. Representations of the Company. The Company represents that all
corporate actions on the part of the Company, its officers, directors and
shareholders necessary for the sale and issuance of the Shares pursuant hereto
and the performance of the Company's obligations hereunder were taken prior to
and are effective as of the effective date of this Warrant.

      7. Representations and Warranties by the Holder. The Holder represents and
warrants to the Company as follows:

      (a) This Warrant and the Shares issuable upon exercise thereof are being
acquired for its own account, for investment and not with a view to, or for
resale in connection with, any distribution or public offering thereof within
the meaning of the Securities Act of 1933, as amended (the "Act"). Upon exercise
of this Warrant, the Holder shall, if so requested by the Company, confirm in
writing, in a form satisfactory to the Company, that the securities issuable
upon exercise of this Warrant are being acquired for investment and not with a
view toward distribution or resale.


                                       4
<PAGE>

      (b) The Holder understands that the Warrant and the Shares have not been
registered under the Act by reason of their issuance in a transaction exempt
from the registration and prospectus delivery requirements of the Act pursuant
to Section 4(2) thereof, and that they must be held by the Holder indefinitely,
and that the Holder must therefore bear the economic risk of such investment
indefinitely, unless a subsequent disposition thereof is registered under the
Act or is exempted from such registration.

      (c) The Holder has such knowledge and experience in financial and business
matters that it is capable of evaluating the merits and risks of the purchase of
this Warrant and the Shares purchasable pursuant to the terms of this Warrant
and of protecting its interests in connection therewith.

      (d) The Holder is able to bear the economic risk of the purchase of the
Shares pursuant to the terms of this Warrant.

      (e) The Holder is an "accredited investor" as defined in the Act.

      8. Restrictive Legend.

      The Shares (unless registered under the Act) shall be stamped or imprinted
with a legend in substantially the following form:

      THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE BEEN ACQUIRED FOR
INVESTMENT AND NOT WITH A VIEW TO, OR IN CONNECTION WITH, THE SALE OR
DISTRIBUTION THEREOF, 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 UNLESS THE COMPANY RECEIVES AN OPINION OF COUNSEL
REASONABLY ACCEPTABLE TO IT STATING THAT SUCH SALE OR TRANSFER IS EXEMPT FROM
THE REGISTRATION AND PROSPECTUS DELIVERY REQUIREMENTS OF THE ACT.

      9. Restrictions Upon Transfer and Removal of Legend.

      (a) The Company need not register a transfer of this Warrant or Shares
bearing the restrictive legend set forth in Section 8 hereof, unless the
conditions specified in such legend are satisfied. The Company may also instruct
its transfer agent not to register the transfer of the Shares, unless one of the
conditions specified in the legend referred to in Section 8 hereof is satisfied.

      (b) Notwithstanding the provisions of paragraph (a) above, no opinion of
counsel shall be necessary for a transfer without consideration by any holder
(i) if such holder is a partnership, to a partner or retired partner of such
partnership who retires after the date hereof or to the estate of any such
partner or retired partner, or (ii) if such holder is a corporation, to a
shareholder of such corporation, or to any other corporation under common
control, direct or indirect, with such holder.

      10. Rights of Shareholders. No holder of this Warrant shall be entitled,
as a Warrant holder, to vote or receive dividends or be deemed the holder of any
Shares or any other securities of the Company which may at any time be issuable

of a stockholder of the Company or any right to vote for the election of
directors or upon any matter submitted to shareholders at any meeting thereof,
or to give or withhold consent to any corporate action (whether upon any
recapitalization, issuance of stock, reclassification of stock, change of par
value, consolidation, merger, conveyance, or otherwise) or to receive notice of

Warrant shall have been exercised and the Shares purchasable upon the exercise
hereof shall have become deliverable, as provided herein. The holder of this
Warrant will not be entitled to share in the assets of the Company in the event
of a liquidation, dissolution or the winding up of the Company.
