                          COMMON STOCK PURCHASE WARRANT

                       Original Issue Date: March 2, 2005
                            Void After: March 2, 2010

                            This Warrant is Issued to
                             SOUTHRIDGE PARTNERS LP

(hereinafter called the "Holder," which term shall include the Holder's legal
representatives, heirs, successors and assigns) by Global Matrechs, Inc., a
Delaware corporation (hereinafter referred to as the "Company"). This Warrant
may be transferred by the Holder only in accordance with the provisions of
Section 12.

     1. Exercise of Warrant. For value received and subject to the terms and
conditions hereinafter set forth, the Holder is entitled, upon surrender of this
Warrant at any time on or after March 2, 2005 and on or prior to March 2, 2010
(the "Exercise Date") (with the subscription form annexed hereto (the
"Subscription Form") duly executed) at the office of the Company at 90 Grove
Street, Suite 201, Ridgefield, Connecticut 06877, or such other office in the
United States of which the Company shall notify the Holder hereof in writing, to
purchase from the Company, at the purchase price hereinafter specified (as
adjusted from time to time, the "Exercise Price"), 7,000,000 shares (the
"Warrant Shares") (as adjusted from time to time) of the Common Stock, $0.0001
par value per share, of the Company (the "Common Stock"). The initial Exercise
Price shall be $0.025 per share.

     2. Issuance of Stock Certificates. As promptly as practicable after
surrender of this Warrant and receipt of payment of the Exercise Price, the
Company shall issue and deliver to the Holder a certificate or certificates for
the shares purchased hereunder, in certificates of such denominations and in
such names as the Holder may specify.

<PAGE>

     3. Payment of Exercise Price. Payment of the Exercise Price shall be made
by check made payable to the order of the Company or wire transfer of funds to a
bank account designated by the Company.

     4. Cashless Exercise. The Holder may notify the Company in a Subscription
Form of its election to utilize cashless exercise, in which event the Company
shall issue to the Holder the number of Warrant Shares determined as follows:

                             X = Y [(A-B)/A]

                    where:

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

                             Y = the number of Warrant Shares with
                             respect to which this Warrant is being
                             exercised.

                             A = the average of the closing prices for
                             the five trading days immediately prior to
                             (but not including) the Exercise Date.

                             B = the Exercise Price.

For purposes of Rule 144 promulgated under the Securities Act, it is intended,
understood and acknowledged that the Warrant Shares issued in a cashless
exercise transaction shall be deemed to have been acquired by the Holder, and
the holding period for the Warrant Shares shall be deemed to have commenced, on
the date this Warrant was originally issued.

     5. Limitation on Exercise. Notwithstanding anything to the contrary
contained herein, the number of Warrant Shares that may be acquired by the
Holder upon any exercise of this Warrant (or otherwise in respect hereof) shall
be limited to the extent necessary to insure that, following such exercise (or
other issuance), the total number of shares of Common Stock then beneficially
owned by such Holder and its affiliates and any other persons whose beneficial
ownership of Common Stock would be aggregated with the Holder's for purposes of
Section 13(d) of the Exchange Act, does not exceed 4.999% of the total number of
issued and outstanding shares of Common Stock (including for such purpose the
shares of Common Stock issuable upon such exercise). For such purposes,
beneficial ownership shall be determined in accordance with Section 13(d) of the
Exchange Act and the rules and regulations promulgated thereunder.

     6. Adjustment for Dividends, Distributions, Subdivisions, Combinations,
Mergers, Consolidations or Sale of Assets.

          6.1 Manner of Adjustment.

               (a) Stock Dividends, Distributions or Subdivisions. In the event
the Company shall issue shares of Common Stock in a stock dividend,

                                        2
<PAGE>

stock distribution or subdivision, the Exercise Price in effect immediately
before such stock dividend, stock distribution or subdivision shall,
concurrently with the effectiveness of such stock dividend, stock distribution
or subdivision, be proportionately decreased and the number of shares of Common
Stock purchasable by exercise of this Warrant shall be proportionately
increased.

               (b) Combinations or Consolidations. In the event the outstanding
shares of Common Stock shall be combined or consolidated, by reclassification or
otherwise, into a lesser number of shares of Common Stock, the Exercise Price in
effect immediately prior to such combination or consolidation shall,
concurrently with the effectiveness of such combination or consolidation, be
proportionately increased and the number of shares of Common Stock purchasable
by exercise of this Warrant shall be proportionately decreased.

               (c) Adjustment for Reclassification, Exchange or Substitution. In
the event that the class of securities issuable upon the exercise of this
Warrant shall be changed into the same or a different number of shares of any
class or classes of stock, whether by capital reorganization, reclassification
or otherwise (other than any event addressed by Sections 6.1(a), 6.1(b) or
6.1(d)), then and in each such event the Holder shall have the right thereafter
to exercise this Warrant for the kind and amount of shares of stock and other
securities and property receivable upon such reorganization, reclassification,
or other change, by holders of the number of shares of the class of securities
into which such Warrant might have been exercisable for immediately prior to
such reorganization, reclassification, or change, all subject to further
adjustment as provided herein.

               (d) Adjustment for Merger, Consolidation or Sale of Assets. In
the event that the Company shall merge or consolidate with or into another
entity or sell all or substantially all of its assets, this Warrant shall
thereafter be exercisable for the kind and amount of shares of stock or other
securities or property to which a holder of the number of shares of Common Stock
of the Company deliverable upon exercise of this Warrant would have been
entitled upon such consolidation, merger or sale; and, in such case, appropriate
adjustment (as determined in good faith by the Company's Board of Directors)
shall be made in the application of the provisions set forth in this Section 6
with respect to the rights and interest thereafter of the Holder of this
Warrant, to the end that the provisions set forth in this Section 6 shall
thereafter be applicable, as nearly as reasonably may be, in relation to any
shares of stock or other property thereafter deliverable upon the exercise of
this Warrant.

          6.2 Certificate as to Adjustments. Upon the occurrence of each
adjustment or readjustment of the Exercise Price pursuant to this Section 6, the
Company at its expense shall promptly compute such adjustment or readjustment in
accordance with the terms hereof and furnish to the Holder a certificate setting
forth such adjustment or readjustment and showing in detail the facts upon which
such adjustment or readjustment is based.

          6.3 Closing of Books. The Company shall at no time close its transfer
books against the transfer of any shares of Common Stock issued or issuable upon
the exercise of this Warrant in any manner which interferes with the timely and
proper issuance of such shares.

     7. Covenants of the Company. 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 the purpose of issue upon exercise of the
rights evidenced hereby, a sufficient number of shares of the class of
securities issuable upon exercise of this Warrant to provide for

                                        3
<PAGE>

the exercise of such rights. All securities which may be issued upon the
exercise of the rights represented by this Warrant shall, upon issuance, be duly
authorized, validly issued, fully paid and non-assessable and free from all
taxes, liens and charges with respect to the issue thereof. Upon surrender for
exercise, this Warrant shall be canceled and shall not be reissued; provided,
however, that upon the partial exercise hereof a substitute Warrant of like
tenor and date representing the rights to subscribe for and purchase any such
unexercised portion hereof shall be issued.

     8. Voting Rights. This Warrant shall not entitle the Holder to any voting
rights or any other rights as a stockholder of the Company but upon presentation
of this Warrant with the Subscription Form duly executed and the tender of
payment of the Exercise Price at the office of the Company pursuant to the
provisions of this Warrant, the Holder shall forthwith be deemed a stockholder
of the Company in respect of the securities for which the Holder has so
subscribed and paid.

     9. No Change Necessary. The form of this Warrant need not be changed
because of any adjustment in the Exercise Price or in the number of shares
issuable upon its exercise. A Warrant issued after any adjustment or any partial
exercise or upon replacement may continue to express the same Exercise Price and
the same number of shares (appropriately reduced in the case of partial
exercise) as are stated on this Warrant as initially issued, and that Exercise
Price and that number of shares shall be considered to have been so changed as
of the close of business on the date of adjustment.

     10. Addresses for Notices. All notices, requests, consents and other
communications hereunder shall be in writing, either delivered in hand or mailed
by registered or certified mail, return receipt requested, or sent by facsimile,
and shall be deemed to have been duly made when delivered:

          (a) If to the Holder, to the Holder's address as shown on the books of
the Company; or

          (b) If to the Company, to the address set forth on the first page of
this Warrant.

     11. Substitution. In the case this Warrant shall be mutilated, lost, stolen
or destroyed, the Company shall issue a new Warrant of like tenor and
denomination and deliver the same (a) in exchange and substitution for and upon
surrender and cancellation of any mutilated Warrant, or (b) in lieu of any
Warrant lost, stolen or destroyed, upon receipt of evidence satisfactory to the
Company of the loss, theft, or destruction of such Warrant (including, without
limitation, a reasonably detailed affidavit with respect to the circumstances of
any loss, theft or destruction), and of indemnity (or, in the case of the
initial Holder or any other institutional holder, an indemnity agreement)
satisfactory to the Company.

     12. Transfer Restrictions. This Warrant shall not be transferable by the
Holder and shall be exercisable only by the Holder. Without the prior written
consent of the Company, the Warrant shall not be assigned, pledged or
hypothecated in any way (whether by operation of law or otherwise) and shall not
be subject to execution, attachment or similar process. Any

                                        4
<PAGE>

attempted transfer, assignment, pledge, hypothecation or other disposition of
the Warrant or of any rights granted hereunder contrary to the provisions of
this Section 12, or the levy of any attachment or similar process upon the
Warrant or such rights, shall be null and void.

     13. Taxes. The Company makes no representation about tax treatment to the
Holder with respect to receipt or exercise of the Warrant or acquiring, holding
or disposing of the Common Stock, and the Holder represents that the Holder has
had the opportunity to discuss such treatment with the Holder's tax advisers.

     14. Remedies. Each party stipulates that the remedies at law in the event
of any default or threatened default by the other party in the performance or
compliance with any of the terms of this Warrant are and shall not be adequate,
and that such terms may be specifically enforced by a decree for that specific
performance of any agreement contained herein or by an injunction against a
violation of any of the terms hereof or otherwise.

     15. Governing Law. This Warrant shall be construed and enforced in
accordance with, and governed by, the laws of the State of New York without
regard to its principles of conflicts of laws.

     16. Miscellaneous. This Warrant and any term hereof may be changed, waived,
discharged or terminated only by an instrument in writing signed by the Holder
and the Company.

To:  Global Matrechs, Inc.
     90 Grove Street, Suite 201
     Ridgefield, CT  06877

     The undersigned, pursuant to the provisions set forth in the attached
Warrant hereby irrevocably elects to purchase _____ shares of the Common Stock
(the "Common Stock") covered by such Warrant and herewith makes payment of
$_________, representing the [full/partial] purchase price for such shares at
the price per share provided for in such Warrant.

     The undersigned hereby agrees to take such other action and execute and
deliver such other documents as Global Matrechs, Inc. may require, in connection
with the issue of shares of Common Stock to the undersigned as aforesaid, in
order to comply with the provisions of such Warrant.

     The undersigned is aware that the Common Stock has not been registered
under the Securities Act of 1933, as amended (the "Act") or any state securities
laws. The undersigned understands that the reliance by the Company on exemptions
under the Act is predicated in part upon the truth and accuracy of the
statements of the undersigned in this Subscription Form.

     The undersigned represents and warrants that (1) it has been furnished with
all information which it deems necessary to evaluate the merits and risks of the
purchase of the Common Stock; (2) it has had the opportunity to ask questions
concerning the Common Stock and the Company and all questions posed have been
answered to its satisfaction; (3) it has been given the opportunity to obtain
any additional information it deems necessary to verify the accuracy of any
information obtained concerning the Common Stock and the Company; and (4) it has
such knowledge and experience in financial and business matters that it is able
to evaluate the merits and risks of purchasing the Common Stock and to make an
informed investment decision relating thereto.

     The undersigned hereby represents and warrants that it is purchasing the
Common Stock for its own account and not with a view to the sale or distribution
of all or any part of the Common Stock.

     The undersigned understands that because the Common Stock have not been
registered under the Act, it must continue to bear the economic risk of the
investment for an indefinite time and the Common Stock cannot be sold unless the
Common Stock are subsequently registered under applicable federal and state
securities laws or an exemption from such registration is available.

     The undersigned agrees that it shall in no event sell or distribute or
otherwise dispose of all or any part of the Common Stock unless (1) there is an
effective registration statement under

<PAGE>

the Act and applicable state securities laws covering any such transaction
involving the Common Stock or (2) the Company receives an opinion of legal
counsel to the undersigned (concurred in by legal counsel for the Company)
stating that such transaction is exempt from registration or the Company
otherwise satisfies itself that such transaction is exempt from registration.

     The undersigned consents to the placing of a legend on its certificate for
the Common Stock stating that the Common Stock has not been registered and
setting forth the restriction on transfer contemplated hereby and to the placing
of a stop transfer order on the books of the Company and with any transfer
agents against the Common Stock until the Common Stock may be legally resold or
distributed without restriction.

     The undersigned has considered the Federal and state income tax
implications of the exercise of the Warrant and the purchase and subsequent sale
of the Common Stock.
