I.      SUBSCRIPTION

        I elect to participate in the 2000 Employee Stock Purchase Plan (the
"PLAN") of WebSideStory, Inc. (the "COMPANY") and to subscribe to purchase
shares of the Company's Common Stock in accordance with this Subscription
Agreement and the Plan.

        I authorize payroll deductions of __________ percent (in whole
percentages not less than 1%, unless an election to stop deductions is being
made, or more than 10%) of my "COMPENSATION" on each payday throughout the
"OFFERING PERIOD" in accordance with the Plan. I understand that these payroll
deductions will be accumulated for the purchase of shares of Common Stock at the
applicable purchase price determined in accordance with the Plan. Except as
otherwise provided by the Plan, I will automatically purchase shares on each
"PURCHASE DATE" unless I withdraw from the Offering or the Plan by giving
written notice on a form provided by the Company or unless my eligibility or
employment terminates.

        I understand that I will automatically participate in each subsequent
Offering that commences immediately after the last day of an Offering in which I
am participating until I withdraw from the Plan by giving written notice on a
form provided by the Company or my eligibility or employment terminates.

        Shares I purchase under the Plan should be issued in the name(s) set
forth below. (Shares may be issued in the participant's name alone or together
with the participant's spouse as community property or in joint tenancy.)

        NAME(S) (please print):
                               -------------------------------------------------

        ADDRESS:
                ----------------------------------------------------------------

        MY SOCIAL SECURITY NUMBER:
                                  ----------------------------------------------

        I agree to make adequate provision for the federal, state, local and
foreign tax withholding obligations, if any, which arise upon my purchase of
shares under the Plan and/or my disposition of shares. The Company may withhold
from my compensation the amount necessary to meet such withholding obligations.

        I agree that, unless otherwise permitted by the Company, until I dispose
of shares I purchase under the Plan, I will hold such shares in the name(s)
entered above (and not in the name of any nominee) until the later of (i) two
years after the first day of the Offering Period in which I purchased the shares
and (ii) one year after the Purchase Date on which I purchased the shares. This
restriction only applies to the name(s) in which shares are held and does not
affect my ability to dispose of Plan shares.

        I AGREE THAT I WILL NOTIFY THE CHIEF FINANCIAL OFFICER OF THE COMPANY IN
WRITING WITHIN 30 DAYS AFTER ANY SALE, GIFT, TRANSFER OR OTHER DISPOSITION OF
ANY KIND PRIOR TO THE END OF THE PERIODS

                              NOTICE OF WITHDRAWAL


NAME (Please print):
                     -----------------------------------------------------------
                      (Last)                  (First)                  (Middle)

(TM) Withdrawal from Plan in full.

(TM) Partial withdrawal of payroll deductions from Plan account.

I.      WITHDRAWAL IN FULL

        I elect to withdraw from the WebSideStory, Inc. 2000 Employee Stock
Purchase Plan (the "PLAN") and the Offering which began on (date)
____________________ and in which I am participating (the "CURRENT OFFERING").

        ELECT EITHER A OR B BELOW:

(TM)    A.     IMMEDIATE TERMINATION. I elect to terminate immediately my
               participation in the Current Offering and the Plan. I request
               that the Company cease all further payroll deductions under the
               Plan (provided I have given sufficient notice before the next
               payday). My payroll deductions not previously used to purchase
               shares should not be used to purchase shares in the Current
               Offering. Instead, I request that all such amounts be paid to me
               as soon as practicable. I understand that this election
               immediately terminates my interest in the Current Offering and in
               the Plan.

(TM)    B.     TERMINATION AFTER NEXT PURCHASE. I elect to terminate my
               participation in the Plan following my purchase of shares on the
               next Purchase Date of the Current Offering. I request that the
               Company cease all further payroll deductions under the Plan
               (provided I have given sufficient notice before the next payday).
               All payroll deductions credited to my Plan account should be used
               to purchase shares on the next Purchase Date of the Current
               Offering to the extent permitted by the Plan. I understand that
               this election will terminate my interest in the Plan immediately
               following such purchase. I request that any cash balance
               remaining in my Plan account after my purchase of shares be paid
               to me as soon as practicable.

        I understand that I am terminating my interest in the Plan and that no
further payroll deductions will be made (provided I have given sufficient notice
before the next payday), unless I elect to become a participant in another
Offering by filing a new Subscription Agreement with the Company. I understand
that I will receive no interest on the amounts paid to me from my Plan account,
and that I may not apply such amounts to any other Offering under the Plan or
any other employee stock purchase plan of the Company.

II.     PARTIAL WITHDRAWAL OF PAYROLL DEDUCTIONS

        Amount of withdrawal requested: $________________________

        I request that the above amount not previously used to purchase shares
under the Plan be withdrawn from my Plan account and paid to me as soon as
practicable. If the amount requested constitutes the entire balance of my Plan
account, I understand that I will be treated as having elected to withdraw in
full from the Plan in accordance with alternative A above. I understand that I
will receive no interest on the amounts paid to me from my Plan account and that
I may not apply such amounts to any other Offering under the Plan or any other
employee stock purchase plan of the Company.
