         THIS WARRANT ANTIDILUTION AGREEMENT (the "Agreement") is entered into
as of December 22, 2000, by and among E-REX, INC., a corporation duly organized
and existing under the laws of the State of Nevada (the "Company") and Swartz
Private Equity, LLC (hereinafter referred to as "Swartz").

                                    RECITALS:

         WHEREAS, pursuant to the Company's offering ("Equity Line") of up to
Fifteen Million Dollars ($15,000,000), excluding any funds paid upon exercise of
the Warrants, of Common Stock of the Company pursuant to that certain Investment
Agreement (the "Investment Agreement") between the Company and Swartz dated on
or about December 22, 2000, the Company has agreed to sell and Swartz has agreed
to purchase, from time to time as provided in the Investment Agreement, shares
of the Company's Common Stock for a maximum aggregate offering amount of Fifteen
Million Dollars ($15,000,000);

         WHEREAS, pursuant to the terms of the Investment Agreement, the Company
has agreed, among other things, to issue to Swartz Commitment Warrants, as
defined in the Investment Agreement, to purchase a number of shares of Common
Stock, exercisable for seven (7) years from their respective dates of issuance;
and

         WHEREAS, unless otherwise noted, capitalized terms shall have the

         NOW, THEREFORE, in consideration of the mutual promises,
representations, warranties, covenants and conditions set forth in Agreement and
for other good and valuable consideration, the receipt and sufficiency of which
is hereby acknowledged, the parties hereto agree as follows:

1. Issuance of Commitment Warrants. As compensation for entering into the Equity

Company's Common Stock, in the form attached hereto as Exhibit A
(the "Commitment Warrants").

2. Issuance of Additional Warrants. On each six month anniversary of the date of

initially equal 9.0%, and shall be reduced by 0.5% for each Six Month
Anniversary Date after the first Six Month Anniversary Date. The Additional
Warrants shall initially be exerciseable at the same price as the Commitment
Warrants (as most recently reset), shall have the same reset provisions as the
Commitment Warrants (which resets shall occur on each six month anniversary of
the date of

                                       1

issuance of the applicable Additional Warrant throughout the term of
the applicable Additional Warrant), shall have piggyback registration rights and
shall have a 7-year term.

3. Opinion of Counsel. Concurrently with the issuance and delivery of the
Commitment Opinion (as defined in the Investment Agreement) to the Investor, or
on the date that is six (6) months after the date of this Agreement, whichever
is sooner, the Company shall deliver to the Investor an Opinion of Counsel
(signed by the Company's independent counsel) covering the issuance of the
Commitment Warrants and the Additional Warrants, and the issuance and resale of
the Common Stock issuable upon exercise of the Warrants and the Additional
Warrants.

4. Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the State of Georgia applicable to agreements made
in and wholly to be performed in that jurisdiction, except for matters arising
under the Act or the Securities Exchange Act of 1934, which matters shall be
construed and interpreted in accordance with such laws.

5. Term. This Agreement shall terminate on the Termination Date of the
Investment Agreement.

         IN WITNESS WHEREOF, the undersigned have executed this Agreement as of
this 22nd day of December, 2000.

Warrant to Purchase
2,700,000 shares

                        Warrant to Purchase Common Stock
                                       of
                                   E-REX, INC.

         THIS CERTIFIES that Swartz Private Equity, LLC or any subsequent holder
hereof pursuant to Section 8 hereof ("Holder"), has the right to purchase from
E-REX, INC., a Nevada corporation (the "Company"), up to 2,700,000 fully paid
and nonassessable shares of the Company's common stock, $.001 par value per
share ("Common Stock"), subject to adjustment as provided herein, at a price
equal to the Exercise Price as defined in Section 3 below, at any time beginning
on the Date of Issuance (defined below) and ending at 5:00 p.m., New York, New
York time the date that is seven (7) years after the Date of Issuance (the
"Exercise Period").

         Holder agrees with the Company that this Warrant to Purchase Common
Stock of the Company (this "Warrant") is issued and all rights hereunder shall
be held subject to all of the conditions, limitations and provisions set forth
herein.

         1.       Date of Issuance and Term.
                  --------------------------

         This Warrant shall be deemed to be issued on September 22, 2000 ("Date
of Issuance"). The term of this Warrant is seven (7) years from the Date of
Issuance.

         Of this Warrant to purchase two million seven hundred thousand
(2,700,000) shares of Common Stock of the Company, the Warrant is exercisable as
to nine hundred thousand (900,000) shares of Common Stock of the Company after
the fifteen (15) business day document review period (the "Review Period")
referenced in the Equity Line Letter of Agreement dated on or about September
22, 2000, between Holder and Company (the "Letter of Agreement") has ended,
shall be further exercisable as to an additional nine hundred thousand (900,000)
shares of Common Stock of the Company upon the execution by the Company and
Swartz Private Equity, LLC of an Investment Agreement, pursuant to the Letter of
Agreement ("Investment Agreement") and shall be

                                       1

<PAGE>

further exercisable as to the remaining nine hundred thousand (900,000) shares
of Common Stock of the Company upon the earlier of (i) the date of effectiveness
of Company's registration statement (the "Registration Statement") to be filed
pursuant to the Investment Agreement and related documents, or (ii) March 22,
2001.

         Anything in this Warrant to the contrary notwithstanding, if the
Company delivers written notice to Swartz Private Equity, LLC prior to the
expiration of the Review Period that the legal documents for the transaction are
unacceptable and the Company wishes to terminate the transaction (a "Company
Termination Notice"), Holder shall return this Warrant to the Company and all of
Holder's rights under this Warrant shall be null and void and of no effect,
provided that, if the Company has not delivered a Company Termination Notice to
Swartz Private Equity, LLC, prior to the expiration of the Review Period,
ownership of this Warrant shall irrevocably vest to the Holder, regardless of
whether a Company Termination Notice is delivered anytime thereafter.

         Notwithstanding anything to the contrary herein, the applicable portion
of this Warrant shall not be exercisable during any time that, and only to the
extent that, the number of shares of Common Stock to be issued to Holder upon
such exercise, when added to the number of shares of Common Stock, if any, that
the Holder otherwise beneficially owns at the time of such exercise, would equal
or exceed 4.99% of the number of shares of Common Stock then outstanding, as
determined in accordance with Section 13(d) of the Exchange Act (the "4.99%
Limitation"). The 4.99% Limitation shall be conclusively satisfied if the
applicable Exercise Notice includes a signed representation by the Holder that
the issuance of the shares in such Exercise Notice will not violate the 4.99%
Limitation, and the Company shall not be entitled to require additional
documentation of such satisfaction.

         2.       Exercise.
                  --------

         (a) Manner of Exercise. During the Exercise Period, this Warrant may be
exercised as to all or any lesser number of full shares of Common Stock covered
hereby (the "Warrant Shares") upon surrender of this Warrant, with the Exercise
Form attached hereto as Exhibit A (the "Exercise Form") duly completed and
executed, together with the full Exercise Price (as defined below) for each
share of Common Stock as to which this Warrant is exercised, at the office of
the Company, Attention: Carl E. Dilley, President & CEO, E-Rex, Inc., 8890 Coral
Way #220, Miami, FL 33165; Telephone: (305) 554-9903, Facsimile: (305) 552-5149,
or at such other office or agency as the Company may designate in writing, by
overnight mail, with an advance copy of the Exercise Form sent to the Company
and its Transfer Agent by facsimile (such surrender and payment of the Exercise
Price hereinafter called the "Exercise of this Warrant").

         (b) Date of Exercise. The "Date of Exercise" of the Warrant shall be
defined as the date that the advance copy of the completed and executed Exercise
Form is sent by facsimile to the Company, provided that the original Warrant and
Exercise Form are received by the Company as soon as practicable thereafter.
Alternatively, the Date of Exercise shall be defined as the date the original
Exercise Form is received by the Company, if Holder has not sent advance notice
by facsimile.

                                       2

<PAGE>

         (c) Delivery of Shares of Common Stock Upon Exercise. Upon any exercise
of this Warrant, the Company shall use its reasonable best efforts to deliver,
or shall cause its transfer agent to deliver, a stock certificate or
certificates representing the number of shares of Common Stock into which this
Warrant was exercised, within five (5) trading days (the "Share Delivery
Deadline") of the date that all of the following have been received by the
Company: (i) the original completed and executed Exercise Form, (ii) the
original Warrant and (iii) the Exercise Price (if applicable)(collectively, the
"Receipt Date"). Such stock certificates shall not contain a legend restricting
transfer if a registration statement covering the resale of such shares of
Common Stock has been filed by the Company and declared effective by the
Securities and Exchange Commission, and is current and effective at the time of
such exercise or if such shares of Common Stock, in the reasonable opinion of
the Company or its counsel, may be resold pursuant to an exemption from
registration, including but not limited to Rule 144 under the Securities Act of
1933.

         (d) Buy-In Cure. If (i) the Company fails for any reason to deliver the
requisite number of shares of Common Stock (unlegended, if so required by the
terms of this Warrant)(the "Warrant Shares") to a Holder upon an exercise of
this Warrant by the Share Delivery Deadline, (ii) the Holder has sold some or
all of the Warrant Shares (the "Sold Shares") which such Holder anticipated
receiving upon such Exercise, and (iii) after the applicable Share Delivery
Deadline with respect to such Exercise, the broker that sold the Sold Shares for
Holder purchases (in an open market transaction or otherwise) shares of Common
Stock to make delivery upon the sale by a Holder of the Sold Shares (a
"Buy-In"), the Company shall pay such Holder within two (2) business days
following receipt of written notice of a claim pursuant to this Section 2(d) (in
addition to any other remedies available to Holder) the amount (a "Buy-In
Payment") by which (x) such Holder's total purchase price (including brokerage
commission, if any) for the shares of Common Stock so purchased exceeds (y) the
net proceeds received by such Holder from the sale of the Sold Shares. For
example, if a Holder purchases shares of Common Stock having a total purchase
price of $11,000 to cover a Buy-In with respect to shares of Common Stock sold
for $10,000, the Company will be required to pay such Holder $1,000. A Holder
shall provide the Company written notification indicating any amounts payable to
Holder pursuant to this Section 2(d).

         (e) [Intentionally Left Blank].

         (f) Cancellation of Warrant. This Warrant shall be canceled upon the
Exercise of this Warrant, and, as soon as practical after the Date of Exercise,
Holder shall be entitled to receive Common Stock for the number of shares
purchased upon such Exercise of this Warrant, and if this Warrant is not
exercised in full, Holder shall be entitled to receive a new Warrant (containing
terms identical to this Warrant) representing any unexercised portion of this
Warrant in addition to such Common Stock.

         (g) Holder of Record. Each person in whose name any Warrant for shares
of Common Stock is issued shall, for all purposes, be deemed to be the Holder of
record of such shares on the Date of Exercise of this Warrant, irrespective of
the date of delivery of the Common Stock purchased upon the Exercise of this
Warrant. Nothing in this Warrant shall be construed as conferring upon Holder
any rights as a stockholder of the Company.

                                       3

<PAGE>

         3.       Payment of Warrant Exercise Price.
                  ---------------------------------

         The Exercise Price per share ("Exercise Price") shall initially equal
(the "Initial Exercise Price") the lowest Closing Price for the five (5) trading
days immediately preceding September 22, 2000, which is $0.50. If the lowest
Closing Price of the Company's Common Stock for the five (5) trading days
immediately preceding the date, if any, that Swartz Private Equity, LLC executes
an Investment Agreement pursuant to the Letter of Agreement (the "Closing Market
Price") is less than the Initial Exercise Price, the Exercise Price shall be
reset to equal the Closing Market Price, or, if the Date of Exercise is more
than six (6) months after the Date of Issuance, the Exercise Price shall be
reset to equal the lesser of (i) the Exercise Price then in effect, or (ii) the
"Lowest Reset Price," as that term is defined below. The Company shall calculate
a "Reset Price" on each six-month anniversary date of the Date of Issuance which
shall equal the lowest Closing Price of the Company's Common Stock for the five
(5) trading days ending on such six-month anniversary date of the Date of
Issuance. The "Lowest Reset Price" shall equal the lowest Reset Price determined
on any six-month anniversary date of the Date of Issuance preceding the Date of
Exercise, taking into account, as appropriate, any adjustments made pursuant to
Section 5 hereof. Notwithstanding the above if all of the following are true on
the date of an Exercise of this Warrant, then the Exercise Price with respect to
that Exercise only shall be $.50 (subject to any adjustments required under
Section 5 of this Warrant), notwithstanding any price resets that would
otherwise apply pursuant to this Section 3: (A) the Company has not completed a
reverse stock split anytime after the Date of Issuance through and including the
date of such Exercise, (B) the lowest Closing Price of the Company's Common
Stock for the five (5) trading days immediately preceding the date of such
Exercise is $3.00 or greater.

         For purposes hereof, the term "Closing Price" shall mean the closing
price on the Nasdaq Small Cap Market, the National Market System ("NMS"), the
New York Stock Exchange, or the O.T.C. Bulletin Board, or if no longer traded on
the Nasdaq Small Cap Market, the National Market System ("NMS"), the New York
Stock Exchange, or the O.T.C. Bulletin Board, the "Closing Price" shall equal
the closing price on the principal national securities exchange or the
over-the-counter system on which the Common Stock is so traded and, if not
available, the mean of the high and low prices on the principal national
securities exchange on which the Common Stock is so traded.

         Payment of the Exercise Price may be made by either of the following,
or a combination thereof, at the election of Holder:

         (i)      Cash Exercise: cash, bank or cashiers check or wire transfer;
or

         (ii) Cashless Exercise: The Holder, at its option, may exercise this
Warrant in a cashless exercise transaction under this subsection (ii) if and
only if, on the Date of Exercise, there is not then in effect a current
registration statement that covers the resale of the shares of Common Stock to
be issued upon exercise of this Warrant . In order to effect a Cashless
Exercise, the Holder shall surrender this Warrant with the Exercise Form at the
principal office of the Company together with notice of cashless election, in
which event the Company shall issue Holder a number of shares of Common Stock
computed using the following formula:

                                       4

<PAGE>

                                            X = Y (A-B)/A

where:   X = the number of shares of Common Stock to be issued to Holder.

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

                  A = the Market Price of one (1) share of Common Stock (for
                  purposes of this Section 3(ii), where the "Market Price" shall
                  be defined as the average Closing Price of the Common Stock
                  for the five (5) trading days prior to the Date of Exercise of
                  this Warrant (the "Average Closing Price"), as reported by the
                  O.T.C. Bulletin Board, National Association of Securities
                  Dealers Automated Quotation System ("Nasdaq") Small Cap
                  Market, or if the Common Stock is not traded on the Nasdaq
                  Small Cap Market, the Average Closing Price in any other
                  over-the-counter market; provided, however, that if the Common
                  Stock is listed on a stock exchange, the Market Price shall be
                  the Average Closing Price on such exchange for the five (5)
                  trading days prior to the date of exercise of the Warrants. If
                  the Common Stock is/was not traded during the five (5) trading
                  days prior to the Date of Exercise, then the closing price for
                  the last publicly traded day shall be deemed to be the closing
                  price for any and all (if applicable) days during such five
                  (5) trading day period.

                  B = the Exercise Price.

         Notwithstanding the above, the Holder shall not be entitled to exercise
this Warrant in a Cashless Exercise until after the date that is ninety (90)
days after the Date of Issuance and, if the Company has entered into a
Registration Rights Agreement with Swartz Private Equity, LLC in conjunction
with the Investment Agreement and the Company has filed a Registration Statement
pursuant to such Registration Rights Agreement within ninety (90) days of the
date of such Registration Rights Agreement, then the Holder shall not be
entitled to exercise this Warrant in a Cashless Exercise until after the date
that is six (6) months after the Date of Issuance.

         For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is
intended that the Common Stock issuable upon exercise of this Warrant in a
cashless exercise transaction shall be deemed to have been acquired at the time
this Warrant was issued. Moreover, it is intended, understood and acknowledged
that the holding period for the Common Stock issuable upon exercise of this
Warrant in a cashless exercise transaction shall be deemed to have commenced on
the date this Warrant was issued. Notwithstanding the above, if a determination
contrary to the above is made as a matter of law by a court or governmental
agency of competent jurisdiction, then such determination shall govern, and the
Company's acting in accordance with such determination shall not give rise to a
default under this paragraph.

         4.       Transfer and Registration.
                  -------------------------

         (a) Transfer Rights. Following an assignment permitted by and in
accordance with Section 8 of this Warrant, this Warrant may be transferred on
the books of the

                                       5

Company, in whole or in part, in person or by attorney, upon surrender of this
Warrant properly completed and endorsed. This Warrant shall be canceled upon
such surrender and, as soon as practicable thereafter, the person to whom such
transfer is made shall be entitled to receive a new Warrant or Warrants as to
the portion of this Warrant transferred, and Holder shall be entitled to receive
a new Warrant as to the portion hereof retained.

         (b) Registrable Securities. In addition to any other registration
rights of the Holder, if the Common Stock issuable upon exercise of this Warrant
is not registered for resale at the time the Company proposes to register
(including for this purpose a registration effected by the Company for
stockholders other than the Holders) any of its Common Stock under the Act
(other than a registration relating solely for the sale of securities to
participants in a Company stock plan or a registration on Form S-4 promulgated
under the Act or any successor or similar form registering stock issuable upon a
reclassification, upon a business combination involving an exchange of
securities or upon an exchange offer for securities of the issuer or another
entity)(a "Piggyback Registration Statement"), the Company shall cause to be
included in such Piggyback Registration Statement ("Piggyback Registration") all
of the Common Stock issuable upon the exercise of this Warrant ("Registrable
Securities") to the extent such inclusion does not violate the registration
rights of any other securityholder of the Company granted prior to the date
hereof. Nothing herein shall prevent the Company from withdrawing or abandoning
the Piggyback Registration Statement prior to its effectiveness.

         (c) Limitation on Obligations to Register under a Piggyback
Registration. In the case of a Piggyback Registration pursuant to an
underwritten public offering by the Company, if the managing underwriter
determines and advises in writing that the inclusion in the registration
statement of all Registrable Securities proposed to be included would interfere
with the successful marketing of the securities proposed to be registered by the
Company, then the Company shall not be required to register all of the
Registrable Securities in such underwritten public offering and the number of
such Registrable Securities to be included in the Piggyback Registration
Statement, to the extent such Registrable Securities may be included in such
Piggyback Registration Statement, shall be allocated among all Holders who had
requested Piggyback Registration pursuant to the terms hereof, in the proportion
that the number of Registrable Securities which each such Holder seeks to
register bears to the total number of Registrable Securities sought to be
included by all Holders. If required by the managing underwriter of such an
underwritten public offering, the Holders shall enter into an agreement,
reasonably acceptable to the Company, limiting the number of Registrable
Securities to be included in such Piggyback Registration Statement and the
terms, if any, regarding the future sale of such Registrable Securities.

         5.       Anti-Dilution Adjustments.
                  -------------------------

         (a) Stock Dividend. If the Company shall at any time declare a dividend
payable in shares of Common Stock, then Holder, upon Exercise of this Warrant
after the record date for the determination of holders of Common Stock entitled
to receive such dividend, shall be entitled to receive upon Exercise of this
Warrant, in addition to the number of shares of Common Stock as to which this
Warrant is exercised, such additional shares of Common Stock as such Holder
would have received had this Warrant been exercised immediately prior to such
record date and the Exercise Price will be proportionately adjusted.

         (b)      Recapitalization or Reclassification.

                  (i) Stock Split. If the Company shall at any time effect a
recapitalization, reclassification or other similar transaction of such
character that the shares of Common Stock shall be changed into or become
exchangeable for a larger number of shares (a "Stock Split"), then upon the
effective date thereof, the number of shares of Common Stock which Holder shall
be entitled to purchase upon Exercise of this Warrant shall be increased in
direct proportion to the increase in the number of shares of Common Stock by
reason of such recapitalization, reclassification or similar transaction, and
the Exercise Price shall be proportionally decreased.

                  (ii) Reverse Stock Split. If the Company shall at any time
effect a recapitalization, reclassification or other similar transaction of such
character that the shares of Common Stock shall be changed into or become
exchangeable for a smaller number of shares (a "Reverse Stock Split"), then upon
the effective date thereof, the number of shares of Common Stock which Holder
shall be entitled to purchase upon Exercise of this Warrant shall be
proportionately decreased and the Exercise Price shall be proportionally
increased. The Company shall give Holder the same notice it provides to holders
of Common Stock of any transaction described in this Section 5(b).

         (c) Distributions. If the Company shall at any time distribute for no
consideration to holders of Common Stock cash, evidences of indebtedness or
other securities or assets (other than cash dividends or distributions payable
out of earned surplus or net profits for the current or preceding years) then,
in any such case, Holder shall be entitled to receive, upon Exercise of this
Warrant, with respect to each share of Common Stock issuable upon such exercise,
the amount of cash or evidences of indebtedness or other securities or assets
which Holder would have been entitled to receive with respect to each such share
of Common Stock as a result of the happening of such event had this Warrant been
exercised immediately prior to the record date or other date fixing shareholders
to be affected by such event (the "Determination Date") or, in lieu thereof, if
the Board of Directors of the Company should so determine at the time of such
distribution, a reduced Exercise Price determined by multiplying the Exercise
Price on the Determination Date by a fraction, the numerator of which is the
result of such Exercise Price reduced by the value of such distribution
applicable to one share of Common Stock (such value to be determined by the
Board of Directors of the Company in its discretion) and the denominator of
which is such Exercise Price.

         (d) Notice of Consolidation or Merger and Warrant Exchange. The Company
shall not, at any time after the date hereof, effect a merger, consolidation,
exchange of shares, recapitalization, reorganization, or other similar event, as
a result of which shares of Common Stock shall be changed into the same or a
different number of shares of the same or another class or classes of stock or
securities or other assets of the Company or another entity or there is a sale
of all or substantially all the Company's assets (a "Corporate Change"), unless
the resulting successor or acquiring entity (the "Resulting Entity") assumes by
written instrument the Company's obligations under this Warrant, including but
not limited to the Exercise Price reset provisions as provided herein during the
term of the resultant warrants, and agrees in such written instrument that this
Warrant shall be exerciseable into such class and type of securities or other
assets of the Resulting Entity as Holder would have received had Holder
exercised this Warrant immediately prior to such Corporate Change, and the
Exercise Price of this Warrant shall be proportionately increased (if this
Warrant shall be changed into or become exchangeable for a warrant to purchase a
smaller number of shares of Common Stock of the Resulting Entity) or shall be
proportionately decreased (if this Warrant shall be changed or become
exchangeable for a warrant to purchase a larger number of shares of Common Stock
of the Resulting Entity); provided, however, that Company may not affect any
Corporate Change unless it first shall have given thirty (30) days notice to
Holder hereof of any Corporate Change.

         (e) Exercise Price Adjusted. As used in this Warrant, the term
"Exercise Price" shall mean the purchase price per share specified in Section 3
of this Warrant, until the occurrence of an event stated in subsection (a), (b),
(c) or (d) of this Section 5, and thereafter shall mean said price as adjusted
from time to time in accordance with the provisions of this Warrant. No such
adjustment under this Section 5 shall be made unless such adjustment would
change the Exercise Price at the time by $0.01 or more; provided, however, that
all adjustments not so made shall be deferred and made when the aggregate
thereof would change the Exercise Price at the time by $0.01 or more.

         (f) Adjustments: Additional Shares, Securities or Assets. In the event
that at any time, as a result of an adjustment made pursuant to this Section 5,
Holder shall, upon Exercise of this Warrant, become entitled to receive shares
and/or other securities or assets (other than Common Stock) then, wherever
appropriate, all references herein to shares of Common Stock shall be deemed to
refer to and include such shares and/or other securities or assets; and
thereafter the number of such shares and/or other securities or assets shall be
subject to adjustment from time to time in a manner and upon terms as nearly
equivalent as practicable to the provisions of this Section 5.

         6.       Fractional Interests.
                  --------------------

                  No fractional shares or scrip representing fractional shares
shall be issuable upon the Exercise of this Warrant, but on Exercise of this
Warrant, Holder may purchase only a whole number of shares of Common Stock. If,
on Exercise of this Warrant, Holder would be entitled to a fractional share of
Common Stock or a right to acquire a fractional share of Common Stock, such
fractional share shall be disregarded and the number of shares of Common Stock
issuable upon exercise shall be the next higher number of shares.

         7.       Reservation of Shares.
                  ---------------------

                  The Company shall at all times reserve for issuance such
number of authorized and unissued shares of Common Stock (or other securities
substituted therefor as herein above provided) as shall be sufficient for the
Exercise of this Warrant and payment of the Exercise Price. The Company
covenants and agrees that upon the Exercise of this Warrant, all shares of
Common Stock issuable upon such exercise shall be duly and validly issued, fully
paid, nonassessable and not subject to preemptive rights, rights of first
refusal or similar rights of any person or entity.

         8.       Restrictions on Transfer.
                  ------------------------

                  (a) Registration or Exemption Required. This Warrant has been
issued in a transaction exempt from the registration requirements of the Act by
virtue of Regulation D and exempt from state registration under applicable state
laws. The Warrant and the Common Stock issuable upon the Exercise of this
Warrant may not be pledged, transferred, sold or assigned unless (i) done
pursuant to an effective registration statement or a valid exemption from
registration under applicable securities laws, which is supported by an opinion
from the Investor's counsel ("Investor's Opinion") to the effect that such
registration is not required, and (ii) the transfer complies with any applicable
state and federal securities laws and does not cause the initial issuance of
this Warrant to violate applicable state or federal securities laws; provided
that, if no registration covering the resale of the Warrant Shares is effective
at the time the Warrant Shares are issued, the Holder consents to a legend being
placed on certificates for the Warrant Shares stating that the securities have
not been registered under the Securities Act and referring to such restrictions
on transferability and sale.

                  (b) Assignment. Subject to the restrictions set forth in
subsection (a) above, Holder may sell, transfer, assign, pledge or otherwise
dispose of this Warrant, in whole or in part. Holder shall deliver a written
notice to Company, substantially in the form of the Assignment attached hereto
as Exhibit B, indicating the person or persons to whom the Warrant shall be
assigned and the respective number of warrants to be assigned to each assignee,
the Investor's Opinion (as defined above) and any required information or
documentation required to satisfy an exemption under applicable securities laws
(e.g., if required, an investor questionnaire, etc.). The Company shall effect
any valid assignment within ten (10) days, and shall deliver to the assignee(s)
designated by Holder a Warrant or Warrants of like tenor and terms for the
appropriate number of shares, within a commercially reasonable time after
receipt of Holder's notices.

         9.       Benefits of this Warrant.
                  ------------------------

                  Nothing in this Warrant shall be construed to confer upon any
person other than the Company and Holder any legal or equitable right, remedy or
claim under this Warrant and this Warrant shall be for the sole and exclusive
benefit of the Company and Holder.

         10.      Applicable Law.
                  --------------

                  ---------------

                  Upon receipt by the Company of evidence of the loss, theft,
destruction or mutilation of this Warrant, and (in the case of loss, theft or
destruction) of indemnity or security reasonably satisfactory to the Company,
and upon surrender and cancellation of this Warrant, if mutilated, the Company
shall execute and deliver a new Warrant of like tenor and date.

         12.      Notice or Demands.
                  -----------------
