                        Warrant to Purchase Common Stock
                                       of
                              BROWSESAFE.COM, INC.

        THIS CERTIFIES that Michael Mercier or any subsequent holder hereof
pursuant to Section 8 hereof ("Holder"), has the right to purchase from
BROWSESAFE.COM, INC.., a Nevada corporation (the "Company"), up to 79,167 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 five (5) 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 February 10, 2000 ("Date of
Issuance"). The term of this Warrant is five (5) years from the Date of
Issuance.

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

                                       1
<PAGE>

        (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: Mark Smith, President, 335 West 9th Street, Suite 100,
Indianapolis, Indiana 46202-3003, phone (317) 633-6656 x113, fax (317) 633-6655
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.

        (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 per share ("Exercise Price") shall initially equal
(the "Initial Exercise Price") $0.50. If the Date of Exercise is more than six
(6) months after the Date of Issuance, 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 one hundred percent (100%) of the average
Closing Bid 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.

                                       3
<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: 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 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 Bid 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 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
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

                                       3
<PAGE>

prices on the principal national securities exchange on which the Common Stock
is so traded.

        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.

        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. 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, other than a "private equity line,"
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 number of such Registrable
Securities to be included in the Piggyback Registration Statement, to the extent
such

                                       4
<PAGE>

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 a reasonable agreement 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

                                       5
<PAGE>

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 exercisable 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.

        (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

                                       6
<PAGE>

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 unless the Company has received an opinion
from the Company's counsel to the effect that such registration is not required,
or the Holder has furnished to the Company an opinion of the Holder's counsel,
which counsel shall be reasonably satisfactory to the Company, to the effect
that such registration is not required; the transfer complies with any
applicable state securities laws; and, 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. 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.

        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

                                       7
<PAGE>

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 Nevada,
without giving effect to conflict of law provisions thereof. In any dispute the
prevailing party shall be entitled to attorneys fees and all costs, including
the costs of collection.

                                       8
<PAGE>

        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.
               -----------------
