THIS WARRANT AND THE SHARES ISSUABLE HEREUNDER HAVE NOT BEEN REGISTERED UNDER
THE SECURITIES ACT OF 1933, AS AMENDED, AND MAY NOT BE SOLD, PLEDGED OR
OTHERWISE TRANSFERRED WITHOUT AN EFFECTIVE REGISTRATION THEREOF UNDER SUCH ACT
OR PURSUANT TO RULE 144 OR AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO THE
CORPORATION AND ITS COUNSEL THAT SUCH REGISTRATION IS NOT REQUIRED.

                           WARRANT TO PURCHASE STOCK

Corporation:                 WEBSIDESTORY, INC., a Delaware Corporation
Number of Shares:            231,840
Class of Stock:              Common
Initial Exercise Price:      $0.647 per share
Issue Date:                  February 2 2001
Expiration Date:             February 2, 2006 (Subject to Article 4.1)

      THIS WARRANT CERTIFIES THAT, in consideration of the payment of $1.00 and
for other good and valuable consideration, IMPERIAL CREDITCORP or its assignee
("Holder") is entitled to purchase the number of fully paid and nonassessable
shares of the class of securities (the "Shares") of the corporation (the
"Company") at the initial exercise price per Share (the "Warrant Price") all as
set forth above and as adjusted pursuant to Article 2 of this warrant, subject
to the provisions and upon the terms and conditions set forth in this warrant.

                                    ARTICLE 1

                                    EXERCISE

      1.1   METHOD OF EXERCISE. Holder may exercise this warrant by delivering
this warrant and a duly executed Notice of Exercise in substantially the form
attached as Appendix 1 to the principal office of the Company. Unless Holder is
exercising the conversion right set forth in Section 1.2, Holder shall also
deliver to the Company a check for the aggregate Warrant Price for the Shares
being purchased.

      1.2   CONVERSION RIGHT. In lieu of exercising this warrant as specified in
Section 1.1, Holder may from time to time convert this warrant, in whole or in
part, into a number of Shares determined by dividing (a) the aggregate fair
market value of the Shares or other securities otherwise issuable upon exercise
of this warrant minus the aggregate Warrant Price of such Shares by (b) the fair
market value of one Share. The fair market value of the Shares shall be
determined pursuant to Section 1.4.

      1.3   [Intentionally Omitted.]

      1.4   FAIR MARKET VALUE. If the Shares are traded regularly in a public
market, the fair market value of the Shares shall be the closing price of the
Shares (or the closing price of the Company's stock into which the Shares are
convertible) reported for the business day immediately before Holder delivers
its Notice of Exercise to the Company. If the Shares are not regularly traded in
a public market, the Board of Directors of the Company shall determine fair
market value in its reasonable good faith judgment. The foregoing
notwithstanding, if Holder

                                       1
<PAGE>

advises the Board of Directors in writing that Holder disagrees with such
determination, then the Company and Holder shall promptly agree upon a reputable
investment banking firm to undertake such valuation. If the valuation of such
investment banking firm is greater than that determined by the Board of
Directors, then all fees and expenses of such investment banking firm shall be
paid by the Company. In all other circumstances, such fees and expenses shall be
paid by Holder.

      1.5   DELIVERY OF CERTIFICATE AND NEW WARRANT. Promptly after Holder
exercises or converts this warrant, the Company shall deliver to Holder
certificates for the Shares acquired and, if this warrant has not been fully
exercised or converted and has not expired, a new warrant representing the
Shares not so acquired.

      1.6   REPLACEMENT OF WARRANTS. On receipt of evidence reasonably
satisfactory to the Company of the loss, theft, destruction or mutilation of
this warrant and, in the case of loss, theft or destruction, on delivery of an
indemnity agreement reasonably satisfactory in form and amount to the Company
or, in the case of mutilation, on surrender and cancellation of this warrant,
the Company at its expense shall execute and deliver, in lieu of this warrant, a
new warrant of like tenor.

      1.7   REPURCHASE ON SALE, MERGER, OR CONSOLIDATION OF THE COMPANY.

            1.7.1 "ACQUISITION." For the purpose of this warrant, "Acquisition"
means any sale, license, or other disposition of all or substantially all of the
assets (including intellectual property) of the Company, or any reorganization,
consolidation, or merger of the Company where the holders of the Company's
securities before the transaction beneficially own less than 50% of the
outstanding voting securities of the surviving entity after the transaction.

            1.7.2 MANDATORY ASSUMPTION OF WARRANT. Upon the closing of any
Acquisition the successor entity shall assume the obligations of this warrant,
and this warrant shall be exercisable for the same securities, cash, and
property as would be payable for the Shares issuable upon exercise of the
unexercised portion of this warrant as if such Shares were outstanding on the
record date for the Acquisition and subsequent closing. The warrant Price shall
be adjusted accordingly.

                                    ARTICLE 2

                            ADJUSTMENTS TO THE SHARES

            2.1   STOCK DIVIDENDS, SPLITS, ETC. If the Company declares or pays
a dividend on its common stock payable in common stock, or other securities,
subdivides the outstanding common stock into a greater or lesser amount, as
applicable, of common stock, then upon exercise of this warrant, for each Share
acquired, Holder shall receive, without cost to Holder, the total number and
kind of securities to which Holder would have been entitled had Holder owned the
Shares of record as of the date the dividend or subdivision occurred.

                                       2
<PAGE>

            2.2   RECLASSIFICATION, EXCHANGE OR SUBSTITUTION. Upon any
reclassification, exchange, substitution, or other event that results in a
change of the number and/or class of the securities issuable upon exercise or
conversion of this warrant. Holder shall be entitled to receive, upon exercise
or conversion of this warrant, the number and kind of securities and property
that Holder would have received for the Shares if this warrant had been
exercised immediately before such reclassification, exchange, substitution, or
other event. Such an event shall include any automatic conversion of the
outstanding or issuable securities of the Company of the same class or series as
the Shares to common stock pursuant to the terms of the Company's Articles of
Incorporation upon the closing of a registered public offering of the Company's
common stock. The Company or its successor shall promptly issue to Holder a new
warrant for such new securities or other property. The new warrant shall provide
for adjustments which shall be as nearly equivalent as may be practicable to the
adjustments provided For in this Article 2 including, without limitation,
adjustments to the Warrant Price and to the number of securities or property
issuable upon exercise of the new warrant. The provisions of this Section 2.2
shall similarly apply to successive reclassifications, exchanges, substitutions,
or other events.

            2.3   ADJUSTMENTS FOR COMBINATIONS, ETC. If the outstanding Shares
are combined or consolidated, by reclassification or otherwise, into a lesser
number of shares, the Warrant Price shall be proportionately increased.

            2.4   ADJUSTMENTS FOR DILUTING ISSUANCES. The Warrant Price and the
number of Shares issuable upon exercise of this warrant shall be subject to
adjustment, from time to time, in the manner set forth on EXHIBIT A, if
attached, in the event of Diluting Issuances (as defined on EXHIBIT A).

            2.5   NO IMPAIRMENT. The Company shall not, by amendment of its
Articles of Incorporation or through a reorganization, transfer of assets,
consolidation, merger, dissolution, issue, or sale of securities or any other
voluntary action, avoid or seek to avoid the observance or performance of any of
the terms to be observed or performed under this warrant by the Company, but
shall at all times in good faith assist in carrying out all the provisions of
this Article 2 and in taking all such action as may be necessary or appropriate
to protect Holder's rights under this Article against impairment. If the Company
takes any action affecting the Shares or its common stock other than as
described above that adversely affects Holder's rights under this warrant, the
Warrant Price shall be adjusted downward and the number of Shares issuable upon
exercise of this warrant shall be adjusted upward in such a manner that the
aggregate Warrant Price of this warrant is unchanged.

            2.6   CERTIFICATE AS TO ADJUSTMENTS. Upon each adjustment of the
Warrant Price, the Company at its expense shall promptly compute such
adjustment, and furnish Holder with a certificate of its Chief Financial Officer
setting forth such adjustment and the facts upon which such adjustment is based.
The Company shall, upon written request, furnish Holder a certificate setting
forth the Warrant Price in effect upon the date thereof and the series of
adjustments leading to such Warrant Price.

                               IMPERIAL CREDITCORP
                            ANTI-DILUTION AGREEMENT

      THIS ANTI-DILUTION AGREEMENT is entered into as of February 2, 2001 by and
between IMPERIAL CREDITCORP ("Purchaser") and WEBSIDESTORY, INC. (the
"Company").

                                    RECITALS

      A.    Concurrently with the execution of this Anti-dilution Agreement, the
Purchaser is purchasing from the Company a Warrant to Purchase Stock (the
"Warrant") pursuant to which Purchaser has the right to acquire from the Company
the Shares (as defined in the Warrant).

      B.    By this Anti-dilution Agreement, the Purchaser and the Company
desire to set forth the adjustment in the number of Shares issuable upon
exercise of the Warrant as a result of a Diluting Issuance (as defined below).

      C.    Capitalized terms used herein shall have the same meaning as set
forth in the Warrant.

      NOW, THEREFORE, in consideration of the mutual promises, covenants and
conditions hereinafter set forth, the parties hereto mutually agree as follows:

      SECTION 1. DEFINITIONS. AS USED IN THIS ANTI-DILUTION AGREEMENT, THE
                 FOLLOWING TERMS HAVE THE FOLLOWING RESPECTIVE MEANINGS:

                        (a)   "Option" means any right, option or warrant to
            subscribe for, purchase or otherwise acquire common stock or
            Convertible Securities.

                        (b)   "Convertible Securities" means any evidences of
            indebtedness, shares of stock or other securities directly or
            indirectly convertible into or exchangeable for common stock.

                        (c)   "Issue" means to grant, issue, sell, assume or fix
            a record date for determining persons entitled to receive any
            security (including Options), whichever of the foregoing is the
            first to occur.

                        (d)   "Additional Common Shares" means all common stock
            (including reissued shares) Issued (or deemed to be issued pursuant
            to Section 2) after the date of the Warrant. Additional Common
            Shares does not include, however, any common stock Issued in a
            transaction described in Sections 2.1 and 2.2 of the Warrant; any
            common stock Issued upon conversion of preferred stock outstanding
            on the date of the Warrant; the Shares; or common stock Issued as
            incentive or in a

                                    EXHIBIT A

<PAGE>

            nonfinancing transaction to employees, officers, directors or
            consultants to the Company.

                        (e)   The shares of common stock ultimately Issuable
            upon exercise of an Option (including the shares of common stock
            ultimately Issuable upon conversion or exercise of a Convertible
            Security Issuable pursuant to an Option) are deemed to be Issued
            when the Option is Issued. The shares of common stock ultimately
            Issuable upon conversion or exercise of a Convertible Security
            (other than a Convertible Security Issued pursuant to an Option)
            shall be deemed Issued upon Issuance of the Convertible Security.

      SECTION 2. DEEMED ISSUANCE OF ADDITIONAL COMMON SHARES.

         The shares of common stock ultimately Issuable upon exercise of an
Option (including the shares of common stock ultimately Issuable upon conversion
or exercise of a Convertible Security Issuable pursuant to an Option) are deemed
to be Issued when the Option is Issued. The shares of common stock ultimately
Issuable upon conversion or exercise of a Convertible Security (other than a
Convertible Security Issued pursuant to an Option) shall be deemed Issued upon
issuance of the Convertible Security. The maximum number of shares of common
stock Issuable is determined without regard to any future adjustments permitted
under the instrument creating the Options or Convertible Securities.

      SECTION 3. ADJUSTMENT OF WARRANT PRICE FOR DILUTING ISSUANCES.

      3.1   Weighted Average Adjustment. If the Company issues Additional Common
Shares after the date of the Warrant and the consideration per Additional Common
Share (determined pursuant to Section 9) is less than the Warrant Price in
effect immediately before such Issue (a "Diluting Issuance"), other than with
respect to shares issued to (a) the Company's employees, officer or directors in
connection with their employment or retention of services not to exceed the
number of Shares reserved in the Company's existing equity financing plans, or
(b) customers or vendors in connection with bona fide business transactions, the
Warrant Price in effect immediately before such Issue shall be reduced,
concurrently with such Issue, to a price (calculated to the nearest hundredth of
a cent) determined by multiplying the Warrant Price by a fraction;

         (a)   the numerator of which is the number of shares of common stock
               outstanding immediately before such Issue plus the number of
               shares of common stock that the aggregate consideration
               received by Company for the Additional Common Shares would
               purchase at the Warrant Price in effect immediately before
               such Issue, and

         (b)   the denominator of which is the number of shares of common
               stock outstanding immediately before such Issue plus the
               number of such Additional Shares.

                                    EXHIBIT A

<PAGE>

      (3.2) Adjustment of Number of Shares. Upon each adjustment of the Warrant
Price, the number of Shares Issuable upon exercise of the Warrant shall be
increased to equal the quotient obtained by dividing (a) the product resulting
from multiplying (i) the number of Shares Issuable upon exercise of the Warrant
and (ii) the Warrant Price, in each case as in effect immediately before such
adjustment, by (b) the adjusted Warrant Price.

      3.3   Securities Deemed Outstanding. For the purpose of this Section 3,
all securities Issuable upon exercise of any outstanding Convertible Securities
or Options, Warrants, or other rights to acquire securities of the Company shall
be deemed to be outstanding.

      SECTION 4. NO ADJUSTMENT FOR ISSUANCES FOLLOWING DEEMED ISSUANCES.

            No adjustment to the Warrant Price shall be made upon the exercise
of Options or conversion of Convertible Securities.

      SECTION 5. ADJUSTMENT FOLLOWING CHANGES IN TERMS OF OPTIONS OR CONVERTIBLE
                 SECURITIES.

            If the consideration payable to, or the number of shares of common
stock Issuable by, the Company increases or decreases, respectively, pursuant to
the terms of any outstanding Options or Convertible Securities, the Warrant
Price shall be recomputed to reflect such increase or decrease. The
recomputation shall be made as of the time of the Issuance of the Options or
Convertible Securities. Any changes in the Warrant Price that occurred after
such Issuance because other Additional Common Shares were Issued or deemed
Issued shall also be recomputed.

      SECTION 6. RECOMPUTATION UPON EXPIRATION OR OPTIONS OR CONVERTIBLE
                 SECURITIES.

            The Warrant Price computed upon the original Issue of any Options or
Convertible Securities, and any subsequent adjustments based thereon, shall be
recomputed when any Options or rights of conversion under Convertible Securities
expire without having been exercised. In the case of Convertible Securities or
Options for common stock, the Warrant Price shall be recomputed as if the only
Additional Common Shares Issued were the shares of common stock actually Issued
upon the exercise of such securities, if any, and as if the only consideration
received therefor was the consideration actually received upon the Issue,
exercise or conversion of the Options or Convertible Securities. In the case of
Options for Convertible Securities, the Warrant Price shall be recomputed as if
the only Convertible Securities Issued were the Convertible Securities actually
Issued upon the exercise thereof, if any, and as if the only consideration
received therefor was the consideration actually received by the Company
(determined pursuant to Section 9), if any, upon the Issue of the Options for
the Convertible Securities.

      SECTION 7. LIMIT ON READJUSTMENTS.

            No readjustment of the Warrant Price pursuant to Sections 5 or 6
shall increase the Warrant Price more than the amount of any decrease made in
respect of the Issue of any Options or Convertible Securities.

      SECTION 8. 30 DAY OPTIONS.

            In the case of any Options that expire by their terms not more than
30 days after the date of Issue thereof, no adjustment of the Warrant Price
shall be made until the expiration or exercise of all such Options.

      SECTION 9. COMPUTATION OF CONSIDERATION.

            The consideration received by the Company for the Issue of any
Additional Common Shares shall be computed as follows;

                              (a)   Cash shall be valued at the amount of cash
                  received by the Corporation, excluding amounts paid or payable
                  for accrued interest or accrued dividends.

                              (b)   Property. Property, other than cash, shall
                  be computed at the fair market value thereof at the time of
                  the Issue as determined in good faith by the Board of
                  Directors of the Company.

                              (c)   Mixed Consideration. The consideration for
                  Additional Common Shares Issued together with other property
                  of the Company for consideration that covers both shall be
                  determined in good faith by the Board of Directors.

                              (d)   Options and Convertible Securities. The
                  consideration per Additional Common Share for Options and
                  Convertible Securities shall be determined by dividing:

                                    (i)   the total amount, if any, received or
                        receivable by the Company for the Issue of the Options
                        or Convertible Securities, plus the minimum amount of
                        additional consideration (as set forth in the
                        instruments relating thereto, without regard to any
                        provision contained therein for a subsequent adjustment
                        of such consideration) payable to the Company upon
                        exercise of the Options or conversion of the Convertible
                        Securities, by

                                    (ii)  the maximum number of shares of common
                        stock (as set forth in the instruments relating thereto,
                        without regard to any provision contained therein for a
                        subsequent adjustment of such number) ultimately
                        Issuable upon the exercise of such Options or the
                        conversion of such Convertible Securities.

                               WARRANT TO PURCHASE
                        30,000 SHARES OF COMMON STOCK OF
                               WEBSIDESTORY, INC.

                          (Void after January 1, 2006)

THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933, AS
AMENDED. THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED OR HYPOTHECATED IN THE
ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO THE SECURITIES
UNDER SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY TO THE COMPANY THAT SUCH
REGISTRATION IS NOT REQUIRED OR UNLESS SOLD PURSUANT TO RULE 144 OF SUCH ACT.

THIS WARRANT AND THE SHARES PURCHASABLE HEREUNDER ARE SUBJECT TO RESTRICTIONS ON
TRANSFER AS SET FORTH HEREIN.

      This certifies that Gray Cary Ware & Friedenrich, LLP (the "HOLDER"), or
assigns, for value received, is entitled to purchase from Websidestory, Inc., a
Delaware corporation (the "COMPANY"), subject to the terms set forth below.
30,000 fully paid and nonassessable shares (subject to adjustment as provided
herein) of the Company's Common Stock (the "WARRANT SHARES") for cash at a price
of $0.647 per share (the "EXERCISE PRICE") (subject to adjustment as provided
herein) at any time or from time to time up to and including 5:00 p.m. (Eastern
Time) on the earlier of (i) the closing of the initial underwritten public
offering of the Company's common stock (the "COMMON STOCK"), pursuant to a
registration statement under the Securities Act of 1933, as amended (the "Act"),
with gross proceeds to the Company which exceed $10,000,000, or (ii) January 1,
2006, such earlier day being referred to herein as the "EXPIRATION DATE" upon
surrender to the Company at its principal office (or at such other location as
the Company may advise the Holder in writing) of this Warrant properly endorsed
with the Form of Subscription attached hereto duly filled in and signed and upon
payment in cash or by check of the aggregate Exercise Price for the number of
shares for which this Warrant is being exercised determined in accordance with
the provisions hereof. The Exercise Price is subject to adjustment as provided
in Section 3 of this Warrant. This Warrant is issued subject to the following
terms and conditions:

      1.    EXERCISE, ISSUANCE OF CERTIFICATES, REDUCTION IN NUMBER OF WARRANT
SHARES.

            1.1   GENERAL. This Warrant is exercisable at the option of the
Holder of record hereof on or prior to the Expiration Date, at any time or from
time to time following its issuance, for all or any part of the Warrant Shares
(but not for a fraction of a share) which may be purchased hereunder, as that
number may be adjusted pursuant to Section 3 of this Warrant. The Company agrees
that the Warrant Shares purchased under this Warrant will be and are deemed to
be issued to the Holder hereof as the record owner of such Warrant Shares as of
the close of business on the date on which this Warrant will have been
surrendered, properly endorsed, the completed and executed Form of Subscription
delivered, and payment made for such Warrant Shares. Certificates for the
Warrant Shares so purchased, together with any other securities or property to
which the Holder hereof is entitled upon such exercise, will be delivered to the
Holder hereof by the Company at the Company's expense as soon as practicable
after the rights represented by this Warrant have been so exercised. In case of
a purchase of less than all the Warrant Shares which may be purchased under this
Warrant, the Company will cancel this Warrant and execute and deliver to the
Holder hereof within a reasonable time a new Warrant or Warrants of like tenor
for the balance of the Warrant Shares purchasable under the Warrant surrendered
upon such purchase. Each stock certificate so delivered will be registered in
the name of such Holder.

            1.2   NET ISSUE EXERCISE OF WARRANT. Notwithstanding any provisions
herein to the contrary, in lieu of exercising this Warrant for cash, Holder may
elect to receive shares of Common Stock equal to the value (as determined below)
of this Warrant (or the portion thereof being canceled) by surrender of this
Warrant at the

<PAGE>

principal office of the Company together with the properly endorsed Form of
Subscription in which event the Company will issue to the Holder a number of
shares of Common Stock computed using the following formula:

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

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

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

              A=      the fair market value of one share of the Company's Common
                      Stock (at the date of such calculation); and

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

For purposes of the above calculation, the fair market value of one share of
Common Stock will be determined by the Company's Board of Directors in the good
faith exercise of its reasonable business judgment; provided, however, that if
at the time of such exercise the Company's Common Stock is listed on any
established stock exchange or a national market system, the fair market value
per share will be the average of the closing bid and asked prices of the Common
Stock quoted in the over-the-counter market summary or the last reported sale
price of the Common Stock or the closing price quoted on the NASDAQ National
Market System or on any exchange on which the Common Stock is listed, whichever
is applicable, as published in The Wall Street Journal for the five trading days
prior to the date of determination of fair market value.

      2.    SHARES TO BE FULLY PAID. The Company covenants and agrees that all
Warrant Shares, will, upon issuance and, if applicable, payment of the
applicable Exercise Price, be duly authorized, validly issued, fully paid and
nonassessable, and free of all liens and encumbrances, except for restrictions
on transfer provided for herein or under applicable federal and state securities
laws.

      3.    ADJUSTMENT OF EXERCISE PRICE AND NUMBER OF SHARES. The Exercise
Price and the total number of Warrant Shares will be subject to adjustment from
time to time upon the occurrence of certain events described in this Section 3.
Upon each adjustment of the Exercise Price, the Holder of this Warrant will
thereafter be entitled to purchase, at the Exercise Price resulting from such
adjustment, the number of shares obtained by multiplying the Exercise Price in
effect immediately prior to such adjustment by the number of shares purchasable
pursuant hereto immediately prior to such adjustment, and dividing the product
thereof by the Exercise Price resulting from such adjustment.

            3.1   SUBDIVISION OR COMBINATION OF STOCK. In case the Company will
at any time subdivide its outstanding shares of Common Stock into a greater
number of shares, the Exercise Price in effect immediately prior to such
subdivision will be proportionately reduced and the number of Warrant Shares
issuable hereunder proportionately increased, and conversely, in case the
outstanding shares of the Common Stock of the Company will be combined into a
smaller number of shares, the Exercise Price in effect immediately prior to such
combination will be proportionately increased and the number of Warrant Shares
issuable hereunder proportionately decreased.

            3.2   RECLASSIFICATION. If any reclassification of the capital stock
of the Company or any reorganization, consolidation, merger, or any sale, lease,
license, exchange or other transfer (in one transaction or a series of related
transactions) of all or substantially all, of the business and/or assets of the
Company (the RECLASSIFICATION EVENTS") will be effected in such a way that
holders of Common Stock will be entitled to receive stock, securities, or other
assets or property, then, as a condition of such Reclassification Event lawful
and adequate provisions will be made whereby the Holder hereof will thereafter
have the right to purchase and receive (in lieu of the shares of Common Stock of
the Company immediately theretofore purchasable and receivable upon the exercise
of the rights represented hereby) such shares of stock, securities, or other
assets or property as may be issued or

                                        2
<PAGE>

payable with respect to or in exchange for a number of outstanding shares of
such Common Stock equal to the number of shares of such stock immediately
theretofore purchasable and receivable upon the exercise of the rights
represented hereby. In any Reclassification Event, appropriate provision will be
made with respect to the rights and interests of the Holder of this Warrant to
the end that the provisions hereof (including, without limitation, provisions
for adjustments of the Exercise Price and of the number of Warrant Shares), will
thereafter be applicable, as nearly as may be, in relation to any shares of
stock, securities, or assets thereafter deliverable upon the exercise hereof.

            3.3   ADJUSTMENT FOR DIVIDENDS IN STOCK. In case at any time or from
time to time on or after the date hereof the holders of the Common Stock (or any
shares of stock or other securities at the time receivable upon the exercise of
this Warrant) shall have received or, on or after the record date fixed for the
determination of eligible stockholders, shall have become entitled to receive,
without payment therefor, other or additional stock of the Company by way of
dividend then, and in each case, the Holder of this Warrant shall, upon the
exercise hereof, be entitled to receive, in addition to the number of Warrant
Shares receivable thereupon, and without payment of any additional consideration
therefor, the amount of such other or additional stock of the Company which such
Holder would hold on the date of such exercise had it been the holder of record
of such Common Stock on the date hereof and had thereafter, during the period
from the date hereof to and including the date of such exercise, retained such
Warrant Shares and/or all other additional stock receivable by it as aforesaid
during such period, giving effect to all adjustments called for during such
period by subsections 3.1 and 3.2 of this Section 3.

            3.4   NOTICE OF ADJUSTMENT. Upon any adjustment of the Exercise
Price or any increase or decrease in the number of Warrant Shares, the Company
will give written notice thereof, by first class mail postage prepaid, addressed
to the registered Holder of this Warrant at the address of such Holder as shown
on the books of the Company. The notice will be prepared and signed by the
Company's Chief Financial Officer and will state the exercise Price resulting
from such adjustment and the increase or decrease, if any, in the number of
shares purchasable at such price upon the exercise of this Warrant, setting
forth in reasonable detail the method of calculation and the facts upon which
such calculation is based.

      4.    NO VOTING OR DIVIDEND RIGHTS. Nothing contained in this Warrant will
be construed as conferring upon the holder hereof the right to vote or to
consent to receive notice as a shareholder of the Company on any other matters
or any rights whatsoever as a shareholder of the Company. Except as provided in
Section 3.3 hereof, no dividends or interest will be payable or accrued in
respect of this Warrant or the interest represented hereby or the shares
purchasable hereunder until, and only to the extent that, this Warrant will have
been exercised.

      5.    COMPLIANCE WITH SECURITIES ACT: TRANSFERABILITY OF WARRANT,
DISPOSITION OF SHARES OF COMMON STOCK.

            5.1   COMPLIANCE WITH SECURITIES ACT. The Holder of this Warrant, by
acceptance hereof, agrees that this Warrant and the Warrant Shares to be issued
upon exercise hereof are being acquired for investment and that it will not
offer, sell, or otherwise dispose of this Warrant or any Warrant Shares except
under circumstances which will not result in a violation of the Act or any
applicable state securities laws. This Warrant and all Warrant Shares (unless
registered under the Act) will be stamped or imprinted with a legend in
substantially the following form

            THESE SECURITIES HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT
            OF 1933, AS AMENDED OR THE SECURITIES OR BLUE SKY LAWS OF ANY STATE.
            THEY MAY NOT BE SOLD, OFFERED FOR SALE, PLEDGED, OR HYPOTHECATED IN
            THE ABSENCE OF A REGISTRATION STATEMENT IN EFFECT WITH RESPECT TO
            THE SECURITIES UNDER SUCH ACT OR AN OPINION OF COUNSEL SATISFACTORY
            TO THE COMPANY THAT SUCH REGISTRATION IS NOT REQUIRED, OR UNLESS
            SOLD PURSUANT TO RULE 144 OF SUCH ACT.

            5.2   ACCESS TO INFORMATION; PRE-EXISTING RELATIONSHIP. Holder has
had the opportunity to ask questions of, and to receive answers from,
appropriate executive officers of the Company with respect to the

                                        3
<PAGE>

terms and conditions of the transactions contemplated hereby and with respect to
the business, affairs, financial condition and results of operations of the
Company. Holder has had access to such financial and other information as is
necessary in order for Holder to make a fully informed decision as to investment
in the Company, and has had the opportunity to obtain any additional information
necessary to verify any of such information to which Holder has had access.
Holder further represents and warrants that he has either (i) a pre-existing
relationship with the Company or one or more of its officers or directors
consisting of personal or business contacts of a nature and duration which
enable him to be aware of the character, business acumen and general business
and financial circumstances of the Company or the officer or director with whom
such relationship exists or (ii) such business or financial expertise as to be
able to protect his own interests in connection with the purchase of the Shares.

            5.3   WARRANT NOT TRANSFERABLE. This Warrant and all rights
hereunder are not transferable, in whole or in part, without the prior written
consent of the Company.

            5.4   DISPOSITION OF WARRANT SHARES AND COMMON STOCK. With respect
to any offer, sale, or other disposition of the Warrant or any Warrant Shares,
the Holder hereof and each subsequent Holder of this Warrant agrees to give
written notice to the Company prior thereto, describing briefly the manner
thereof, together with a written opinion of such holder's counsel, if reasonably
requested by the Company, to the effect that such offer, sale or other
disposition may be effected without registration or qualification (under the Act
as then in effect or any federal or state law then in effect) of such Warrant or
Warrant Shares, as the case may be, and indicating whether or not under the Act
certificates for such Warrant or Warrant Shares to be sold or otherwise disposed
of require any restrictive legend as to applicable restrictions on
transferability in order to insure compliance with the Act. Promptly upon
receiving such written notice and opinion, the Company, as promptly as
practicable, will notify such Holder that such Holder may sell or otherwise
dispose of such Warrant or Warrant Shares, all in accordance with the terms of
the notice delivered to the Company. If a determination has been made pursuant
to this subparagraph 5.4 that the opinion of the counsel for the Holder is not
reasonably satisfactory to the Company, the Company will so notify the Holder
promptly after such determination has been made. Notwithstanding the foregoing,
such Warrant or Warrant Shares may be offered, sold or otherwise disposed of in
accordance with Rule 144 under the Act, provided that the Company will have been
furnished with such information as the Company may request to provide reasonable
assurance that the provisions of Rule 144 have been satisfied. Each certificate
representing the Warrant or Warrant Shares thus transferred (except a transfer
pursuant to Rule 144) will bear a legend as to the applicable restrictions on
transferability in order to insure compliance with the Act, unless in the
aforesaid opinion of counsel for the Holder, such legend is not required in
order to insure compliance with the Act. The Company may issue stop transfer
instructions to its transfer agent in connection with such restrictions.

            5.5   MARKET STANDOFF. The Holder agrees that if so requested by the
Company or any representative of the underwriters in connection with
registration of the initial public offering of any securities of the Company
under the Act, the Holder will not sell or otherwise transfer any Warrant Shares
or other securities of the Company during the 180-day period following the
effective date of such registration statement. The Company may impose stop
transfer instructions with respect to securities subject to the foregoing
restrictions until the end of such 180-day period.

      6.    MODIFICATION AND WAIVER. This Warrant and any provision hereof may
be changed, waived, discharged, or terminated only by an instrument in writing
signed by the party against which enforcement of the same is sought.

      7.    NOTICES. Any notice, request, or other document required or
permitted to be given or delivered to the Holder hereof or the Company will be
delivered or will be sent by certified mail, postage prepaid, to each such
Holder at its address as shown on the books of the Company or to the Company at
the address indicated therefor in the first paragraph of this Warrant or such
other address as either may from time to time provide to the other.

surrender and cancellation of such Warrant, the Company, at its expense, will
