                                                   Issue Date:  December 9, 2003

            EPIXTAR CORP., a corporation organized under the laws of the State
of Florida (the "Company"), hereby certifies that, for value received,
____________________, with its principal address at_____________________________
___________________________________________ or assigns (the "Holder"), is
entitled, subject to the terms set forth below, to purchase from the Company
from and after the Issue Date of this Warrant and at any time or from time to

(the "Expiration Date"), up to _______________ fully paid and nonassessable
shares of Common Stock (as hereinafter defined), $.001 par value, of the
Company, at the Exercise Price (as defined below). The number and character of
such shares of Common Stock and the Exercise Price are subject to adjustment as
provided herein.

            As used herein the following terms, unless the context otherwise
requires, have the following respective meanings:

            (a) The term "Company" shall include Epixtar Corp. and any
corporation which shall succeed or assume the obligations of Epixtar Corp.
hereunder.

            (b) The term "Common Stock" includes (a) the Company's Common Stock,
par value $.001 per share, and (b) any other securities into which or for which
any of the securities described in (a) may be converted or exchanged pursuant to

<PAGE>

            (c) The term "Other Securities" refers to any stock (other than
Common Stock) and other securities of the Company or any other person (corporate
or otherwise) which the holder of the Warrant at any time shall be entitled to
receive, or shall have received, on the exercise of the Warrant, in lieu of or
in addition to Common Stock, or which at any time shall be issuable or shall
have been issued in exchange for or in replacement of Common Stock or Other
Securities pursuant to Section 4 or otherwise.

            (d) The term "Exercise Price" shall be five dollars ($5.00) per
share of Common Stock subject to adjustment as provided herein and or provided
in the Registration Rights Agreement.

         1. Exercise of Warrant.

            1.1 Discretionary Exercise. From and after the date hereof through
and including the Expiration Date, the Holder shall be entitled to exercise this
Warrant to acquire shares of Common Stock of the Company at the Exercise Price.

            1.2 Mandatory Exercise. Subject to the conditions set forth
hereafter,one (1) time per each consecutive 90-day period until the Expiration
Date, the Company may require the exercise, at the Exercise Price, of up to 20%

Market Price of the Common Stock is $10.00 or greater for thirty (30)
consecutive trading days (the "Trading Period") ending on the day prior to the
date the Company gives notice that it is requiring exercise (the "Mandatory
Notice"). Within seven (7) business days after the Company provides such
Mandatory Notice, the Holder shall exercise the number of Warrants as required
by such notice. If the Holder fails to exercise the Warrants within the required
time period the number of shares subject to such Warrants shall be automatically
reduced by the number of shares Holder was required to acquire pursuant to such
notice. The period beginning on the first day of the Trading Period and ending
on the seventh business day after the Mandatory Notice shall be defined as the
"Required Period." The Mandatory Notice shall not be given and any request for
exercise pursuant to this section 1.2 shall be of no effect, unless, during the
entire Required Period, there is an effective registration statement covering
the resale of the shares subject to the Warrant with current prospectus
available.

                                       2

<PAGE>

            1.2.1 Market Price. For purposes hereof, the Market Price shall
mean: the 4:00 p.m. closing bid prices for the Common Stock on the OTC Pink
Sheets, NASD OTC Bulletin Board, NASDAQ Small Cap Market, NASDAQ National Market
System, American Stock Exchange, or New York Stock Exchange (whichever of the
foregoing is at the time the principal trading exchange or market for the Common
Stock, the "Principal Market"), or if the shares are not then trading on a
Principal Market, such other market or exchange where the Common Stock is listed
or traded.

         2. Procedure for Exercise.

            2.1 Method of Exercise. Upon surrender of a Warrant Certificate with
the annexed Form of Purchase Election duly executed, together with payment of
the Exercise Price (as hereinafter defined) for the shares of Common Stock
purchased at the Company's principal offices (presently located at 11900
Biscayne Blvd., Miami FL 33181) the registered holder of a Warrant Certificate
("Holder" or "Holders") shall be entitled to receive a certificate or
certificates for the shares of Common Stock. The purchase rights represented by
each Warrant Certificate are exercisable at the option of the Holder thereof, in
whole or in part (but not as to fractional shares of the Common Stock underlying
the Warrants). Warrants may be exercised to purchase all or part of the shares
of Common Stock. In the case of the purchase of less than all the shares of
Common Stock purchasable under any Warrant Certificate, the Company shall cancel
said Warrant Certificate upon the surrender thereof and shall execute and
deliver a new Warrant Certificate of like tenor for the balance of the shares of
Common Stock purchasable thereunder.

            2.2 Delivery of Stock Certificates, etc. on Exercise. The Company
agrees that the shares of Common Stock purchased upon exercise of this Warrant
shall be deemed to be issued to the Holder as the record owner of such shares as
of the close of business on the date on which this Warrant shall have been

                                       3
<PAGE>

surrendered and payment made for such shares as aforesaid. As soon as
practicable after the exercise of this Warrant in full or in part, and in any
event within 5 business 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, or as such Holder (upon payment by such
holder of any applicable transfer taxes) may direct in compliance with
applicable securities laws, a certificate or certificates for the number of duly
and validly issued, fully paid and nonassessable shares of Common Stock (or
Other Securities) to which such Holder shall be entitled on such exercise, plus,
at the Company's election, in lieu of any fractional share to which such holder
would otherwise be entitled, cash equal to such fraction multiplied by the then
Market Value of one full share or an additional share, together with any other
stock or other securities and property (including cash, where applicable) to
which such Holder is entitled upon such exercise pursuant to Section 1 or
otherwise.

            2.3. Payment.

                  (a) Payment may be made either (i) in cash or by certified or
official bank check payable to the order of the Company equal to the applicable
aggregate Exercise Price, (ii) by delivery of the Warrant, Common Stock and/or
Common Stock receivable upon exercise of the Warrant in accordance with Section
(b) below, or (iii) by a combination of any of the foregoing methods, for the
number of Common Shares specified in such form (as such exercise number shall be
adjusted to reflect any adjustment in the total number of shares of Common Stock
issuable to the holder per the terms of this Warrant) and the Holder shall
thereupon be entitled to receive the number of duly authorized, validly issued,
fully-paid and non-assessable shares of Common Stock (or Other Securities)
determined as provided herein.

                  (b) Notwithstanding any provisions herein to the contrary, if,
at the time of an exercise pursuant to either section 1.1 or 1.2, there is no
effective registration statement covering the resale of the Common Stock subject
to this Warrant, with current prospectus available and if the Market Value of
one share of Common Stock at such time is greater than the Exercise Price (at
the date of calculation as set forth below), in lieu of exercising this Warrant
for cash, the Holder may elect to receive shares equal to the value (as
determined below) of this Warrant (or the portion thereof being exercised) by

                                       4
<PAGE>

surrender of this Warrant at the principal office of the Company together with
the properly endorsed Exercise Notice in which event the Company shall issue to
the Holder a number of shares of Common Stock computed using the following
formula:

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

           Where  X =  the number of shares of Common Stock to be issued to the
                       Holder

                  Y =  the number of shares of Common Stock purchasable under
                       the Warrant or, if only a portion of the Warrant is being
                       exercised, the portion of the Warrant being exercised (at
                       the date of such calculation)

                  A =  the Fair Market Value of one share of the Company's
                       Common Stock (at the date of such calculation)

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

         3. Effect of Reorganization and Other Events Affecting Common Stock;
            Adjustment of Exercise Price.

            3.1 Adjusted Exercise Price. Except as hereinafter provided, in case
the Company shall at any time after the date hereof issue or sell any shares of
Common Stock (other than the issuances or sales referred to in Section 3.1 (F)
hereof), including shares held in the Company's treasury, for a consideration
per share less than the Exercise Price in effect immediately prior to the
issuance or sale of such shares, or without consideration, then forthwith upon
such issuance or sale, the Exercise Price shall (until another issuance or sale)
be reduced to the price (calculated to the nearest full cent) equal to the
quotient derived by dividing (i) an amount equal to the sum of (a) the total
number of shares of Common Stock outstanding immediately prior to the issuance
or sale of such shares, multiplied by the Exercise Price in effect immediately
prior to such issuance or sale, and (b) the aggregate of the amount of all
consideration, if any, received by the Company upon such issuance or sale, by
(ii) the total number of shares of Common Stock outstanding immediately after
such issuance or sale; provided, however, that in no event shall the Exercise

                                       5
<PAGE>

Price be adjusted pursuant to this computation to an amount in excess of the
Exercise Price in effect immediately prior to such computation, except in the
case of a combination of outstanding shares of Common Stock, as provided by
Section 3.1(E) hereof.

            For the purposes of this Section 3.1, the term "Exercise Price"
shall mean the Exercise Price per share of Common Stock set forth in the
preamble to this Warrant, as adjusted from time to time pursuant to the
provisions of this Section 3.1.

            In calculating the adjustment to the Exercise Price, the following
apply:

                  A. In case of the issuance or sale of shares of Common Stock
for a consideration, part or all of which shall be cash, the amount of the cash
consideration therefore shall be deemed to be the amount of cash received by the
Company for such shares (or, if shares of Common Stock are offered by the
Company for subscription, the subscription price, or if either of such
securities shall be sold to underwriters or dealers for public offering without
a subscription offering, the initial public offering price) before deducting
therefrom any compensation paid or discount allowed in the sale, underwriting or
purchase thereof by underwriters or dealers or others performing similar
services, or any expenses incurred in connection therewith.

                  B. In case of the issuance or sale (otherwise than as a
dividend or other distribution on any stock of the Company) of shares of Common
Stock for a consideration part or all of which shall be other than cash, the
amount of the consideration therefore other than cash shall be deemed to be the
value of such consideration as determined in good faith by the Board of
Directors of the Company.

                  C. The number of shares of Common Stock at any one time
outstanding shall exclude the aggregate number of shares issued or issuable
(subject to readjustment upon the actual issuance thereof) upon the exercise of
options, rights, warrants and upon the Exercise or exchange of convertible or
exchangeable securities.

                  D. Options, Rights, Warrants and Convertible and Exchangeable
Securities. In case the Company shall at any time after the date hereof issue
options, rights or warrants to subscribe for shares of Common Stock, or issue
any securities convertible into or exchangeable for shares of Common Stock, for
a consideration per share less than the Exercise Price in effect immediately
prior to the issuance of such options, rights or warrants, or such convertible
or exchangeable securities, or without consideration, the Exercise Price in
effect immediately prior to the issuance of such options, rights or warrants, or
such convertible or exchangeable securities, as the case may be, shall be
reduced to a price determined by making a computation in accordance with the
provisions of this Section 3.1, provided that:

                                       6
<PAGE>

                       (1) The aggregate maximum number of shares of Common
Stock, as the case may be, issuable under such options, rights or warrants shall
be deemed to be issued and outstanding at the time such options, rights or
warrants were issued, and for a consideration equal to the minimum purchase
price per share provided for in such options, rights or warrants at the time of
issuance, plus the consideration (determined in the same manner as consideration
received on the issue or sale of shares in accordance with the terms of the Note
Purchase Agreement), if any, received by the Company for such options, rights or
warrants.

                       (2) The aggregate maximum number of shares of Common
Stock issuable upon Exercise or exchange of any convertible or exchangeable
securities shall be deemed to be issued and outstanding at the time of issuance
of such securities, and for a consideration equal to the consideration
(determined in the same manner as consideration received on the issue or sale of
shares of Common Stock in accordance with the terms of the Note Purchase
Agreement) received by the Company for such securities, plus the minimum
consideration, if any, receivable by the Company upon the Exercise or exchange
thereof.

                       (3) If any change shall occur in the price per share
provided for in any of the options, rights or warrants referred to in subsection
(1) of this Section 3.1(D), or in the price per share at which the securities
referred to in subsection (2) of this Section 3.1(D) are convertible or
exchangeable, such options, rights or warrants or Exercise or exchange rights,
as the case may be, shall be deemed to have expired or terminated on the date
when such price change became effective in respect of shares not theretofore
issued pursuant to the exercise or Exercise or exchange thereof, and the Company
shall be deemed to have issued upon such date new options, rights or warrants or
convertible or exchangeable securities at the new price in respect of the number
of shares issuable upon the exercise of such options, rights or warrants or the
Exercise or exchange of such convertible or exchangeable securities.

                 E. Subdivision; Combination, Etc.

                       (1) Stock Splits and Dividends. If outstanding shares of
the common stock shall be subdivided into a greater number of shares or a
dividend in common stock shall be paid in respect of common stock, the Exercise
Price in effect immediately prior to such subdivision or dividend shall
simultaneously with the effectiveness of such subdivision or dividend be
proportionately reduced. If outstanding shares of common stock shall be combined
into a smaller number of shares, the Exercise Price in effect immediately prior
to such combination shall, simultaneously with the effectiveness of such
combination, be proportionately increased.

                       (2) Reclassification, Etc. In case there occurs any
reclassification or change of the outstanding securities of which are at the
time receivable in conjunction with the Note Purchase Agreement or any similar

                                       7
<PAGE>

corporate reorganization on or after the date hereof, then and in each such case
the Holder, upon the exercise hereof at any time after the consummation of such
reclassification, change or reorganization, shall be entitled to receive, in
lieu of common stock, the stock or other securities or property to which such
Holder would have been entitled upon such consummation if such Holder had
converted this Warrant immediately prior thereto, all subject to further
adjustment pursuant to the provisions of this Section 3.1.

                       F. Adjustment in Number of Securities. Upon each
adjustment of the Exercise Price pursuant to the provisions of this Section 3.1,
the number of Securities issuable in conjunction with the Warrant shall be
adjusted to the nearest full amount by multiplying a number equal to the
Exercise Price in effect immediately prior to such adjustment by the number of
Securities issuable in conjunction with the Warrant immediately prior to such
adjustment and dividing the product so obtained by the adjusted Exercise Price.

                       G. Exceptions to Adjustment Requirements. No adjustment
shall be required pursuant to this Section 3.1 upon:

                       (1)  the exercise of any warrants, options or convertible
                            securities granted, issued and outstanding on the
                            date of issuance of this Warrant;

                       (2)  upon the grant or exercise of any stock or options
                            which may hereafter be granted or exercised under
                            any employee stock option plan of the Company now
                            existing or to be implemented in the future, so long
                            as the issuance of such stock or options is approved
                            by a majority of the independent members of the
                            Board of Directors of the Company or a majority of
                            the members of a committee of the independent
                            directors established for such purpose;

                       (3)  any Common Stock issued in connection with a merger
                            or acquisition;

                       (4)  any security issued pursuant to this Note Purchase
                            Agreement or Note Purchase Agreement for unsecured
                            debt securities that have substantially similar
                            terms to the securities issued pursuant to the Note
                            Purchase Agreement;

                       (5)  any Common Stock issued pursuant to a lease line or
                            line of credit; or

                       (6)  any adjustment of thirteen cents ($.13) or less,
                            although such adjustment shall be carried forward
                            and made with the next adjustment (if any).

                                       8

satisfactory to the Company of the loss, theft, destruction or mutilation of
this Warrant and, in the case of any such loss, theft or destruction of this

            13. Miscellaneous. This Warrant and any term hereof may be changed,
waived, discharged or terminated only by an instrument in writing signed by the
party against which enforcement of such change, waiver, discharge or termination
is sought. This Warrant shall be governed by and construed in accordance with
the laws of State of Florida without regard to principles of conflicts of laws.
Any action brought concerning the transactions contemplated by this Warrant
shall be brought only in the state courts of Florida or in the federal courts
located in the state of Florida; provided, however, that the Holder may choose
to waive this provision and bring an action outside the state of Florida. The
individuals executing this Warrant on behalf of the Company agree to submit to
the jurisdiction of such courts and waive trial by jury. The prevailing party
shall be entitled to recover from the other party its reasonable attorney's fees
and costs. In the event that any provision of this Warrant is invalid or
unenforceable under any applicable statute or rule of law, then such provision
shall be deemed inoperative to the extent that it may conflict therewith and
shall be deemed modified to conform with such statute or rule of law. Any such
provision which may prove invalid or unenforceable under any law shall not
affect the validity or enforceability of any other provision of this Warrant.
The headings in this Warrant are for purposes of reference only, and shall not
limit or otherwise affect any of the terms hereof. The invalidity or
unenforceability of any provision hereof shall in no way affect the validity or
enforceability of any other provision. The Company acknowledges that legal
counsel participated in the preparation of this Warrant and, therefore,
stipulates that the rule of construction that ambiguities are to be resolved
against the drafting party shall not be applied in the interpretation of this
Warrant to favor any party against the other party.
