                        Warrant to Purchase Common Stock
                                       of
                                  SHOPPING.COM

     THIS CERTIFIES that Swartz Private Equity, LLC or any subsequent holder
                         ---------------------------                        
hereof ("Holder"), has the right to purchase from SHOPPING.COM, a California
corporation (the "Company"), up to "N" fully paid and nonassessable shares,
wherein "N" is defined below, of the Company's common stock, $.01 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"); provided, that, with respect to each "Put," as that term is
defined in that certain Regulation D Common Stock Equity Line Subscription
Agreement (the "Subscription Agreement") by and between the Holder and Company,
"N" shall equal fifteen percent (15%) of the number of shares of Common Stock
purchased by the Holder in that Put.

     Holder agrees with the Company that this Warrant to Purchase Common Stock
of Shopping.Com (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 _______________, 19__ ("Date 
of Issuance"). The term of this Warrant is seven (7) years from the Date of
Issuance.

     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  
<PAGE>
 
Warrant is exercised, at the office of the Company, Attention: Frank W. Denny,
Chairman, Shopping.Com, 2101 East Coast Highway, Garden Level, Corona Del Mar,
CA 92625, Telephone No. (949) 640-4393, Telecopy No. (949) 640-4374, 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 shall initially equal $Y per share ("Exercise Price"),
where "Y" shall equal 110% of the Closing Bid Price of the Company's Common
Stock on the Pricing Period End Date (as defined in the Subscription Agreement)
for the applicable Put 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 percent (100%) of the lowest 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.

     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:

                                       2
<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), 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 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.

     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
December 14, 1998 by and among the Company and certain investors, or otherwise
be registered under the Securities Act of 1933, as amended.

                                       3
<PAGE>
 
     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 December 14, 1998 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.

     (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

                                       4
<PAGE>
 
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.

     (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.

                                       5
<PAGE>
 
     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

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 Warrant and this Warrant &hall be for the sole and exclusive benefit
of the Company and Holder.

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