         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

                                    EXHIBIT D

(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: Ralph Massetti; President and CEO; SalesRepCentral.Com,
Inc.; 16099 North 82 Street, Suite 181; Scottsdale, AZ 85260; Telephone: (480)
922-8444, Facsimile: (480) 922-8477, 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. The Company shall not be required to deliver the shares of Common
Stock to the Holder until the requirements of Section 2(a) above are satisfied.

         (c) 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.

         (d) 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.       PAYMENT OF WARRANT EXERCISE PRICE.

         The Exercise Price ("Exercise Price"), shall initially equal $Y per
share ("Initial Exercise Price"), where "Y" shall equal 115% of the Market Price
for the applicable Put (as both are defined in the Investment Agreement) or, if
the Date of Exercise is more than six (6) months after the Date of Issuance, the
lesser of (i) the Initial Exercise Price 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 one hundred
and fifteen percent (115%) of the lowest closing bid price of the 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.

                                       2
<PAGE>

         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: subject to the last sentence of this Section 3,
surrender of this Warrant 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:

                                  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), 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.

         For purposes hereof, the term "Closing Bid Price" shall mean the
closing bid price on the O.T.C. Bulletin Board, the National Market System
("NMS"), the New York Stock Exchange, the Nasdaq Small Cap Market, or if no
longer traded on the O.T.C. Bulletin Board, the NMS, the New York Stock
Exchange, the Nasdaq Small Cap Market, the "Closing Bid 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.

<PAGE>

         For purposes of Rule 144 and sub-section (d)(3)(ii) thereof, it is
intended, understood and acknowledged 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 anything to the contrary contained herein, this Warrant
may not be exercised in a cashless exercise transaction if, on the Date of
Exercise, the shares of Common Stock to be issued upon exercise of this Warrant
would upon such issuance be then registered pursuant to an effective
registration statement filed pursuant to that certain Registration Rights
Agreement dated on or about June 9, 2000 by and among the Company and certain
investors, or otherwise be registered under the Securities Act of 1933, as
amended.

         4.       TRANSFER AND REGISTRATION.

         (a) TRANSFER RIGHTS. Subject to the provisions of Section 8 of this
Warrant, this Warrant may be transferred on the books of the 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. The Common Stock issuable upon the exercise
of this Warrant constitutes "Registrable Securities" under that certain
Registration Rights Agreement dated on or about June 9, 2000 between the Company
and certain investors and, accordingly, has the benefit of the registration
rights pursuant to that agreement.

         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.

                                       4
<PAGE>

         (b) RECAPITALIZATION OR RECLASSIFICATION. 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 or smaller number of shares, 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 or
decreased, as the case may be, in direct proportion to the increase or decrease
in the number of shares of Common Stock by reason of such recapitalization,
reclassification or similar transaction, and the Exercise Price shall be, in the
case of an increase in the number of shares, proportionally decreased and, in
the case of decrease in the number of shares, 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. In the event of 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"), then this Warrant shall be exerciseable into such class and type of
securities or other assets as Holder would have received had Holder exercised
this Warrant immediately prior to such Corporate Change; 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)
or (c) of this Section 5, and thereafter shall mean said price as adjusted from
time to time in accordance with the provisions of said subsection. No such
adjustment under this Section 5 shall be made unless such adjustment would
change the Exercise Price at the time by $.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 $.01 or more. No
adjustment made pursuant to any provision of this Section 5 shall have the net
effect of increasing the Exercise Price in relation to the split adjusted and
distribution adjusted price of the Common Stock. The number of shares of Common
Stock subject hereto shall increase proportionately with each decrease in the
Exercise Price.

                                       5
<PAGE>

         (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 except pursuant to an effective
registration statement or an exemption to the registration requirements of the
Act and applicable state laws.

         (b) ASSIGNMENT. If Holder can provide the Company with reasonably
satisfactory evidence that the conditions of (a) above regarding registration or
exemption have been satisfied, 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 Company shall effect the 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.

<PAGE>

         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.

         This Warrant is issued under and shall for all purposes be governed by
and construed in accordance with the laws of the state of Georgia, without
giving effect to conflict of law provisions thereof.

         11.      LOSS OF WARRANT.

         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.

         Notices or demands pursuant to this Warrant to be given or made by
Holder to or on the Company shall be sufficiently given or made if sent by
