                    INTELLECTUAL PROPERTY SECURITY AGREEMENT

     This Intellectual Property Security Agreement (the "Agreement") is made as
of August 4, 1999, by and between WEBSIDESTORY, INC., a California corporation
("Grantor"), and IMPERIAL BANK, a California chartered bank ("Secured Party").

                                    RECITALS

     A.   Secured Party has agreed to lend to Grantor certain funds (the
"Loan"), and Grantor desires to borrow such funds from Secured Party pursuant to
the terms of a Credit Agreement, dated as of August 4, 1999 (the "Credit
Agreement;" all capitalized terms used herein without definition shall have the
meanings ascribed to them in the Credit Agreement).

     B.   In order to induce Secured Party to enter into the Credit Agreement,
Grantor has agreed to grant a security interest in certain intangible property
to Secured Party for purposes of securing the obligations of Grantor to Secured
Party.

     NOW, THEREFORE, THE PARTIES HERETO AGREE AS FOLLOWS:

     1.   Grant of Security Interest. As collateral security for the prompt and
complete payment and performance of all of Grantor's present or future
indebtedness, obligations and liabilities to Secured Party, Grantor hereby
grants a security interest and mortgage to Secured Party, as security, in and to
Grantor's entire right, title and interest in, to and under the following (all
of which shall collectively be called the "Collateral"):

          (a)  Any and all copyright rights, copyright applications, copyright
registrations and like protections in each work or authorship and derivative
work thereof, whether published or unpublished and whether or not the same also
constitutes a trade secret, now or hereafter existing, created, acquired or
held, including without limitation those set forth on Exhibit A attached hereto
(collectively, the "Copyrights");

          (b)  Any and all trade secrets, and any and all intellectual property
rights in computer software and computer software products now or hereafter
existing, created, acquired or held;

          (c)  Any and all design rights which may be available to Grantor now
or hereafter existing, created, acquired or held;

          (d)  All patents, patent applications and like protections including
without limitation improvements, divisions, continuations, renewals, reissues,
extensions and continuations-in-part of the same, including without limitation
the patents and patent applications set forth on Exhibit B attached hereto
(collectively, the "Patents");

          (e)  Any trademark and servicemark rights, whether registered or not,
applications to register and registrations of the same and like protections, and
the entire goodwill of the business of Grantor connected with and symbolized by
such trademarks, including without limitation those set forth on Exhibit C
attached hereto (collectively, the "Trademarks");

          (f)  Any and all claims for damages by way of past, present and future
infringement of any of the rights included above, with the right, but not the
obligation, to sue for and collect such damages for said use or infringement of
the intellectual property rights identified above;

          (g)  All licenses or other rights to use any of the Copyrights,
Patents or Trademarks, and all license fees and royalties arising from such use
to the extent permitted by such license or rights; and

          (h)  All amendments, renewals and extensions of any of the Copyrights,
Trademarks or Patents; and

<PAGE>   2
          (i)  All proceeds and products of the foregoing, including without
limitation all payments under insurance or any indemnity or warranty payable in
respect of any of the foregoing.

     2.   Authorization and Request. Grantor authorizes and requests that the
Register of Copyrights and the Commissioner of Patents and Trademarks record
this security agreement.

     3.   Covenants and Warranties. Grantor represents, warrants, covenants and
agrees as follows:

          (a)  Grantor is now the sole owner of the Collateral, except for
non-exclusive licenses granted by Grantor to its customers in the ordinary
course of business;

          (b)  Performance of this Agreement does not conflict with or result in
a breach of any agreement to which Grantor is party or by which Grantor is
bound, except to the extent that certain intellectual property agreements
prohibit the assignment of the rights thereunder to a third party without the
licensor's or other party's consent and this Agreement constitutes an
assignment;

          (c)  During the term of this Agreement, Grantor will not transfer or
otherwise encumber any interest in the Collateral, except for non-exclusive
licenses granted by Grantor in the ordinary course of business or as set forth
in this Agreement;

          (d)  To its knowledge, each of the Patents is valid and enforceable,
and no part of the Collateral has been judged invalid or unenforceable, in whole
or in part, and no claim has been made that any part of the Collateral violates
the rights of any third party;

          (e)  Grantor shall deliver to Secured Party within (30) days of the
last day of each fiscal quarter, a report signed by Grantor, in form reasonably
acceptable to Secured Party, listing any applications or registrations that
Grantor has made or filed in respect of any patents, copyrights or trademarks
and the status of any outstanding applications or registrations. Grantor shall
promptly advise Secured Party of any material change in the composition of the
Collateral, including but not limited to any subsequent ownership right of the
Grantor in or to any Trademark, Patent or Copyright not specified in this
Agreement;

          (f)  Grantor shall (i) protect, defend and maintain the validity and
enforceability of the Trademarks, Patents and Copyrights (ii) use commercially
reasonable efforts to detect infringements of the Trademarks, Patents and
Copyrights and promptly advise Secured Party in writing of material
infringements detected and (iii) not allow any Trademarks, Patents or Copyrights
to be abandoned, forfeited or dedicated to the public without the written
consent of Secured Party, which shall not be unreasonably withheld, unless
Grantor determines that reasonable business practices suggest the abandonment is
appropriate;

          (g)  Grantor shall register or cause to be registered (to the extent
not already registered) with the United States Patent and Trademark Office or
the United States Copyright Office, as applicable, those intellectual property
rights listed on Exhibits A, B and C hereto within thirty (30) days of the date
of this Agreement, Grantor shall register or cause to be registered with the
United States Patent and Trademark Office or the United States Copyright Office,
as applicable, those additional intellectual property rights developed or
acquired by Grantor from time to time in connection with any product prior to
the sale or licensing of such product to any third party (including without
limitation revisions or additions to the intellectual property rights listed on
such Exhibits A, B and C). Grantor shall, from time to time, execute and file
such other instruments, and take such further actions as Secured Party may
reasonably request from time to time to perfect or continue the perfection of
Secured Party's interest in the Collateral;

          (h)  Grantor has not granted a security interest in the Collateral in
favor of any other Person;

          (i)  To its knowledge, except for, and upon, the filing with the
United States Patent and Trademark office with respect to the Patents and
Trademarks and the Register of Copyrights with respect to the Copyrights
necessary to perfect the security interests created hereunder, and except as has
been already made or obtained, no authorization, approval or other action by,
and no notice to or filing with, any United States

                                       2

<PAGE>   3
governmental authority or United States regulatory body is required for the
grant by Grantor of the security interest granted hereby or for the execution,
delivery or performance of this Agreement by Grantor in the United States;

          (j)  All information heretofore, herein or hereafter supplied to
Secured Party by or on behalf of Grantor with respect to the Collateral is
accurate and complete in all material respects;

          (k)  Grantor shall not enter into any agreement that would
materially impair or conflict with Grantor's obligations hereunder without
Secured Party's prior written consent, which consent shall not be unreasonably
withheld. Grantor shall not permit the inclusion in any material contract to
which it becomes a party of any provisions that could or might in any way
prevent the creation of a security interest in Grantor's rights and interests
in any property included within the definition of the Collateral acquired under
such contracts; and

          (l)  Upon any executive officer of Grantor obtaining actual knowledge
thereof, Grantor will promptly notify Secured Party in writing of any event
that materially adversely affects the value of any Collateral, the ability of
Grantor to dispose of any Collateral or the rights and remedies of Secured
Party in relation thereto, including the levy of any legal process against any
of the Collateral.

     4.   Secured Party's Rights.  Secured Party shall have the right, but not
the obligation, to take, at Grantor's sole expense, any actions that Grantor is
required under this Agreement to take but which Grantor fails to take, after
fifteen (15) days' notice to Grantor. Grantor shall reimburse and indemnify
Secured Party for all reasonable costs and reasonable expenses incurred in the
reasonable exercise of its rights under this section 4.

     5.   Further Assurances: Attorney in Fact.

          (a)  On a continuing basis, Grantor will make, execute, acknowledge
and deliver, and file and record in the proper filing and recording places in
the United States, all such instruments, including appropriate financing and
continuation statements and collateral agreements and filings with the United
States Patent and Trademark Office and the Register of Copyrights, and take all
such action as may reasonably be deemed necessary or advisable, or as requested
by secured Party, to perfect Secured Party's security interest in all
Copyrights, Patents and Trademarks and otherwise to carry out the intent and
purposes of this Agreement, or for assuring and confirming to Secured Party the
grant or perfection of a security interest in all Collateral.

          (b)  Grantor hereby irrevocably appoints Secured Party as Grantor's
attorney-in-fact, with full authority in the place and stead of Grantor and in
the name of Grantor, from time to time in Secured Party's discretion, to take
any action and to execute any instrument which Secured Party may deem necessary
or advisable to accomplish the purposes of this Agreement, including (i) to
modify, in its sole discretion, this Agreement without first obtaining
Grantor's approval of or signature to such modification by amending Exhibit A,
Exhibit B and Exhibit C, thereof, as appropriate, to include reference to any
right, title or interest in any Copyrights, Patents or Trademarks acquired by
Grantor after the execution hereof or to delete any reference to any right,
title or interest in any Copyrights, Patents or Trademarks in which Grantor no
longer has or claims any right, title or interest, (ii) to file, in its sole
discretion, one or more financing or continuation statements and amendments
thereto, relative to any of the Collateral without the signature of Grantor
where permitted by law and (iii) after the occurrence of an Event of Default, to
transfer the Collateral into the name of Bank or a third party to the extent
permitted under the California Uniform Commercial Code.

     6.   Events of Default.  The occurrence of any of the following shall
constitute an Event of Default under the Agreement:

          (a)  An Event of Default occurs under the Credit Agreement; or

          (b)  Grantor breaches any warranty or agreement made by Grantor in
this Agreement and, as to any breach that is capable of cure, Grantor fails to
cure such breach within five (5) days of the occurrence of such breach.

     7.   Remedies.  Upon the occurrence and continuance of an Event of
Default, Secured Party shall have the right to exercise all the remedies of a
secured party under the California Uniform Commercial Code, including

                                       3
<PAGE>   4
without limitation the right to require Grantor to assemble the Collateral and
any tangible property in which Secured Party has a security interest and to
make it available to Secured Party at a place designated by Secured Party.
Secured Party shall have a nonexclusive, royalty free license to use the
Copyrights, Patents and Trademarks to the extent reasonably necessary to permit
Secured Party to exercise its rights and remedies upon the occurrence of an
Event of Default. Grantor will pay any expenses (including reasonable
attorneys' fees) incurred by Secured Party in connection with the exercise of
any Secured Party's rights hereunder, including without limitation any expense
incurred in disposing of the Collateral. All of Secured Party's rights and
remedies with respect to the Collateral shall be cumulative.

     8.   Indemnity. Grantor agrees to defend, indemnify and hold harmless
Secured Party and its officers, employees, and agents against: (a) all
obligations, demands, claims, and liabilities claimed or asserted by any other
party in connection with the transactions contemplated by this Agreement, and
(b) all losses or expenses in any way suffered, incurred, or paid by Secured
Party as a result of or in any way arising out of, following or consequential
to transactions between Secured Party and Grantor, under this Agreement
(including without limitation reasonable attorneys' fees and reasonable
expenses), except for losses arising from or out of Secured Party's gross
negligence or willful misconduct.

     9.   Course of Dealing.  No course of dealing, nor any failure to
exercise, nor any delay in exercising any right, power or privilege hereunder
shall operate as a waiver thereof.

     10.  Attorneys' Fees.  If any action relating to this Agreement is brought
by either party hereto against the other party, the prevailing party shall be
entitled to recover reasonable attorneys' fees, costs and disbursements.

     11.  Amendments.  This Agreement may be amended only by a written
instrument signed by both parties hereto.

     12.  Counterparts.  This Agreement may be executed in two or more
counterparts, each of which shall be deemed an original but all of which
together shall constitute the same instrument.

                                       4
<PAGE>   5
     13.  California Law and Jurisdiction; Jury Waiver. This Agreement shall be
governed by the laws of the State of California, without regard for choice of
law provisions. Grantor and Secured Party consent to the exclusive jurisdiction
of any state or federal court located in Santa Clara County, California.
GRANTOR AND SECURED PARTY EACH WAIVE THEIR RESPECTIVE RIGHTS TO A JURY TRIAL OF
ANY CLAIM OR CAUSE OF ACTION BASED UPON OR ARISING OUT OF THE CREDIT AGREEMENT,
THIS AGREEMENT, OR ANY OF THE TRANSACTIONS CONTEMPLATED HEREIN, INCLUDING
CONTRACT CLAIMS, TORT CLAIMS, BREACH OF DUTY CLAIMS, AND ALL OTHER COMMON LAW
OR STATUTORY CLAIMS.

     IN WITNESS WHEREOF, the parties hereto have executed this Agreement on the
day and year first above written.

                                CREDIT AGREEMENT

This Amended and Restated Credit Agreement ("Agreement") is made and entered
into on March 27, 2000, by and between WEBSIDESTORY, INC., a California
corporation ("Borrower") and IMPERIAL BANK, a California banking corporation,
("Bank").

Subject to the terms and conditions of this Agreement, any security agreement(s)
executed by Borrower in favor of Bank, any note(s) executed by Borrower in favor
of Bank, or any other agreements executed in conjunction therewith
(collectively, the "Loan Documents"), Bank shall make the loan(s) and or
advance(s)(individually a "Loan" and collectively "Loans") referred to below to
Borrower.

In consideration of mutual covenants and conditions hereof, the parties hereto
agree as follows:

1.   AMOUNT AND TERMS OF CREDIT

1.01 REVOLVING CREDIT COMMITMENT.

(a)       REVOLVING LINE OF CREDIT. Subject to the terms and conditions of this
Agreement, provided that no event of default then has occurred and is
continuing, Bank shall, upon Borrower's request make advances ("Revolving
Loans") to Borrower, for general corporate purposes, future capital equipment
expenditures and the issuance of letters of credit, in an amount not to exceed
$3,000,000 (the "Revolving Line of Credit") until April 2, 2001 (the "Revolving
Line of Credit Maturity Date"). Revolving Loans may be repaid and reborrowed,
provided that all outstanding principal and accrued interest on the Revolving
Loans shall be payable in full on the Revolving Line of Credit Maturity Date.

(b)       EQUIPMENT DRAWS. Equipment draws, paid on an interest monthly basis,
made under the Revolving Line of Credit shall be converted to a term loan on
April 2, 2001, which shall provide for thirty-six (36) equal principal payments
plus interest as follows:

          Equipment draws made under the Revolving Line of Credit may include up
to 100% of invoice value excluding soft costs, freight, and sales tax.

          Each equipment advance shall require a detailed schedule of equipment
purchases and other expenses associated with each draw-down.

(c)       REVOLVING NOTE. The interest rate, principal and interest payments,
maturity date and certain other terms of the Revolving Loan will be contained in
a promissory note dated the date of this agreement, as such may be amended or
replaced from time to time.

(d)       LETTER OF CREDIT USAGE AND SUBLIMIT. Subject to availability under the
Revolving Line of Credit, at any time and from time to time from the date hereof
through the banking day immediately prior to the Revolving Line of Credit
Maturity Date, Bank shall issue for the account of Borrower such standby and
commercial letters of credit ("Letters of Credit") as Borrower may request,
which requests shall be made by delivering to Bank a duly executed

letter of credit application on Bank's standard form; provided, however, that
the outstanding and undrawn amounts under all such Letters of Credit (i) shall
not at any time exceed $360,000 ("Letter of Credit Sublimit") and (ii) shall be
deemed to constitute Revolving Loans for the purpose of calculating availability
under the Revolving Line of Credit. If the Revolving Line of Credit is not
renewed upon its maturity date, the Letters of Credit will be secured by
Imperial Bank Time Certificate of Deposits. All Letters of Credit shall be in
form and substance acceptable to Bank in its sole discretion and shall be
subject to the terms and conditions of Bank's form application and letter of
credit agreement and other agreements required by Bank. Borrower will pay all
usual issuance and other fees that Bank notifies Borrower will be charged for
issuing and processing Letters of Credit for Borrower.

(e)       LATE CHARGE. If any installment payment, interest payment, principal
payment or principal balance due under the Revolving Line of Credit is
delinquent ten (10) or more days, Borrower agrees to pay Bank a late charge in
the amount of five percent (5%) of the payment so due and unpaid, in addition
to the payment; but nothing in this paragraph is to be construed as any
obligation on the part of the Bank to accept any past due payment or less than
the total unpaid principal balance after maturity. All payments, at Bank's sole
discretion, shall be applied first to any late charges owing, then to interest
and the remainder, if any, to principal.

(f)       DEFAULT RATE. If an Event of Default occurs hereunder, then during
the continuance thereof at the Bank's option, the interest rate shall be five
percent (5%) per year in excess of the rate otherwise applicable.

(g)       INTEREST CALCULATIONS. The term "Prime Rate" shall mean the rate that
the Bank has announced as its prime lending rate, which shall vary concurrently
with any change in the Prime Rate.

1.02      DOCUMENTATION FEE, COSTS AND EXPENSES. In addition to any other
amounts due, or to become due, concurrently with the execution hereof, Borrower
agrees to pay to Bank a documentation fee in the amount of $250, and all other
costs and expenses incurred by the Bank in the preparation of this Agreement,
the other Loan Documents and the perfection of any security interest granted to
Bank by Borrower.

1.03      COLLATERAL. Borrower shall grant or cause to be granted to Bank a
first priority lien on any and all personal property assets of Borrower which
is assigned or hereafter is assigned to Bank as security or in which Bank now
has or hereafter acquires a security interest or pursuant to the terms of any
security agreement, an intellectual property security agreement or otherwise as
security for all of Borrower's obligations to Bank, all as may be subject to
Section 5.03 hereof.

1.04      COLLECTION OF PAYMENTS. Borrower authorizes Bank to collect all
interest, fees, costs and/or expenses due under this Agreement by charging
Borrower's demand deposit account number 38-051-660 with Bank, or any other
demand deposit account maintained by Borrower with Bank, for the full amount
thereof. Should there be insufficient funds in any such demand deposit account
to pay all such sums when due, the full amount of such deficiency shall be
immediately due and payable by Borrower.

days after the Event of Default, and notice of the occurrence of any Event of
Default by Bank to Borrower.

7.08      Severability.  Should any one or more provisions of the Agreement be

provisions of Section 638 et seq. of the California Code of Civil Procedure, or
their successor section ("CCP"), which shall constitute the exclusive remedy
for the settlement of any controversy, dispute or claim concerning this
Agreement, including whether such controversy, dispute or claim is subject to
the reference proceeding and except as set forth above, the parties waive their
rights to initiate any legal proceedings against each other in any court or
jurisdiction other than the Superior Court in the County where the Real
Property, if any, is located or Los Angeles County if none (the "Court"). The
referee shall be a retired Judge of the Court selected by mutual agreement of
the parties, and if they cannot so agree within forty-five (45) days after the
Claim Date, the referee shall be promptly selected by the Presiding Judge of
the Court (or his representative). The referee shall be appointed to sit as a
temporary judge, with all of the powers for a temporary judge, as authorized by
law, and upon selection should take and subscribe to the oath of office as
provided for in Rule 244 of the California Rules of Court (or any subsequently

having jurisdiction. Any party may apply for a reference proceeding at any time
after thirty (30) days following notice to any other party of the nature of the
controversy, dispute or claim, by filing a petition for a hearing and/or trial.
All discovery permitted by this Agreement shall be completed no later than
fifteen (15) days before the first hearing date established by the referee. The
referee may extend such period in the event of a party's refusal to provide
requested discovery for any reason whatsoever, including, without limitation,
legal objections raised to such discovery or unavailability of a witness due to
absence or illness. No party shall be entitled to "priority" in conducting
discovery. Depositions may be taken by either party upon seven (7) days written
notice, and request for production or inspection of documents shall be
responded to within ten (10) days after service. All disputes relating to
discovery which cannot be resolved by the parties shall be submitted to the
referee whose decision shall be final and binding upon the parties. Pending
appointment of the referee as provided herein, the Superior Court is empowered
to issue temporary and/or provisional remedies, as appropriate.

(b)  Except as expressly set forth in this Agreement, the referee shall
determine the manner in which the reference proceeding is conducted including
the time and place of all hearings, the order of presentation of evidence, and
all other questions that arise with respect to the course of the reference
proceeding. All proceedings and hearings conducted before the referee, except
for trial, shall be conducted without a court reporter except that when any
party so requests, a court reporter will be used at any hearing conducted
before the referee. The party making such a request shall have the obligation
to arrange for and pay for the court reporter. The costs of the court reporter
at the trial shall be borne equally by the parties.

(c)  The referee shall be required to determine all issues in accordance with
existing case law and the statutory laws of the state of California. The rules
of evidence applicable to proceedings at law in the state of California will be
applicable to the reference proceeding. The referee shall be empowered to enter
equitable as well as legal relief, to provide all temporary and/or provisional
remedies and to enter equitable orders that will be binding upon the parties.
The referee shall issue a single judgment at the close of the reference
proceeding which shall dispose of all of the claims of the parties that are the
subject of the reference. The parties hereto expressly reserve the right to
contest or appeal from the final judgment or any appealable order or appealable

of a referee is repealed (and no successor statute is enacted), any dispute
between the parties that would otherwise be determined by the reference
procedure herein described will be resolved and determined by arbitration. The
arbitration will be conducted by a retired judge of the Court, in accordance

PROMISE TO PAY. WEBSIDESTORY, INC. ("Borrower") promises to pay to Imperial
Bank ("Lender"), or order, in lawful money of the United States of America, the
principal amount of Three Million & 00/100 Dollars ($3,000,000.00) or so much
as may be outstanding, together with Interest on the unpaid outstanding
principal balance of each advance. Interest shall be calculated from the date
of each advance until repayment of each advance.

PAYMENT. Borrower will pay this loan in accordance with the following payment
schedule:

         Advances under the Note shall be available through April 2, 2001 (the
         "Revolving Line of Credit Maturity Date"). Prior to such date, interest
         only shall be due monthly beginning May 2, 2000. The outstanding
         principal balance of the advances under the Note used for equipment
         expenditures shall be payable monthly in 36 equal payments of principal
         plus accrued interest beginning May 2, 2001. All principal and accrued
         but unpaid interest for equipment expenditures shall in any event be
         due and payable on or before April 2, 2004. All principal plus accrued
         but unpaid interest for all other purposes shall be due and payable on
         the Revolving Line of Credit Maturity Date.

The annual interest rate for this Note is computed on a 365/360 basis; that is,
by applying the ratio of the annual interest rate over a year of 360 days,
multiplied by the outstanding principal balance, multiplied by the actual
number of days the principal balance is outstanding. Borrower will pay Lender
at Lender's address shown above or at such other place as Lender may designate
in writing. Unless otherwise agreed or required by applicable law, payments
will be applied first to any unpaid collection costs and any late charges, then
to any unpaid interest, and any remaining amount to principal.

VARIABLE INTEREST RATE. The interest rate on this Note is subject to change
from time to time based on changes in an index which is the Imperial Bank Prime
Rate (the "Index"). The Prime Rate is the rate announced by Lender as its Prime
Rate of interest from time to time. Lender will tell Borrower the current index
rate upon Borrower's request. Borrower understands that Lender may make loans
based on other rates as well. The interest rate change will not occur more
often than each day. THE INDEX CURRENTLY IS 9.000%. THE INTEREST RATE TO BE
APPLIED TO THE UNPAID PRINCIPAL BALANCE OF THIS NOTE WILL BE AT A RATE OF 0.250
PERCENTAGE POINTS OVER THE INDEX, RESULTING IN AN INITIAL RATE OF 9.250%.
NOTICE: Under no circumstances will the interest rate on this Note be more than
the maximum rate allowed by applicable law.

PREPAYMENT; MINIMUM INTEREST CHARGE. Borrower agrees that all loan fees and
other prepaid finance charges are earned fully as of the date of the loan and
will not be subject to refund upon early payment (whether voluntary or as a
result of default), except as otherwise required by law. In any event, even
upon full prepayment of this Note, Borrower understands that Lender is entitled
to a minimum interest charge of $250.00. Other than Borrower's obligation to
pay any minimum interest charge, Borrower may pay without penalty all or a
portion of the amount owed earlier than it is due. Early payments will not,
unless agreed to by Lender in writing, relieve Borrower of Borrower's
obligation to continue to make payments of accrued unpaid interest. Rather,
they will reduce the principal balance due.

LATE CHARGE. If a payment is 10 days or more late, Borrower will be charged
5.000% of the unpaid portion of the regularly scheduled payment.

DEFAULT. Borrower will be in default if any of the following happens: (a)
Borrower fails to make any payment when due. (b) Borrower breaks any promise
Borrower has made to Lender, or Borrower fails to comply with or to perform
when due any other term, obligation, covenant, or condition contained in this
Note or any agreement related to this Note, or in any other agreement or loan
Borrower has with Lender. (c) Any representation or statement made or furnished
to Lender by Borrower or on Borrower's behalf is false or misleading in any
material respect either now or at the time made or furnished. (d) Borrower
becomes insolvent, a receiver is appointed for any part of Borrower's property,
Borrower makes an assignment for the benefit of creditors, or any proceeding is
commenced either by Borrower or against Borrower under any bankruptcy or
insolvency laws. (e) Any creditor tries to take any of Borrower's property on
or in which Lender has a lien or security interest. This includes a garnishment
of any of Borrower's accounts with Lender. (f) Any guarantor dies or any of the
other evens described in this default section occurs with respect to any
guarantor of this Note. (g) A material adverse change occurs in Borrower's
financial condition, or Lender believes the prospect of payment or performance
of the indebtedness is impaired. (h) Lender in good faith deems itself insecure.

If any default, other than a default in payment, is curable and if Borrower has
not been given a notice of a breach of the same provision of this Note within
the preceding twelve (12) months, it may be cured (and no event of default will
have occurred) if Borrower, after receiving written notice from Lender
demanding cure of such default: (a) cures that default within ten (10) days; or
(b) if the cure requires more than ten (10) days, immediately initiates steps
which Lender deems in Lender's sole discretion to be sufficient to cure the
default and thereafter continues and completes all reasonable and necessary
steps sufficient to produce compliance as soon as reasonably practical.

LENDER'S RIGHTS. Upon default, Lender may declare the entire unpaid principal
balance on this Note and all accrued unpaid interest immediately due, without
notice, and then Borrower will pay that amount. Upon Borrower's failure to pay
all amounts declared due pursuant to this section, including failure to pay
upon final maturity, Lender, at its option, may also, if permitted under
applicable law, do one or both of the following: (a) increase the variable
interest rate on this Note to 5.250 percentage points over the Index, and (b)
add any unpaid accrued interest to principal and such sum will bear interest
therefrom until paid at the rate provided in this Note (including any increased
rate). Lender may hire or pay someone else to help collect this Note if
Borrower does not pay. Borrower also will pay Lender that amount. This
includes, subject to any limits under applicable law, Lender's attorneys' fees
and Lender's legal expenses whether or not there is a lawsuit, including
attorney's fees and legal expenses for bankruptcy proceedings (including
efforts to modify or vacate any automatic stay or injunction), appeals, and any
anticipated post-judgment collection services. Borrower also will pay any court
costs, in addition to all other sums provided by law. THIS NOTE HAS BEEN
DELIVERED TO LENDER AND ACCEPTED BY LENDER IN THE STATE OF CALIFORNIA. IF THERE
IS A LAWSUIT, BORROWER AGREES UPON LENDER'S REQUEST TO SUBMIT TO THE
JURISDICTION OF THE COURTS OF LOS ANGELES COUNTY, THE STATE OF CALIFORNIA.
LENDER AND BORROWER HEREBY WAIVE THE RIGHT TO ANY JURY TRIAL IN ANY ACTION,
PROCEEDING, OR COUNTERCLAIM BROUGHT BY EITHER LENDER OR BORROWER AGAINST THE
OTHER. (INITIAL HERE MC/JJH) THIS NOTE SHALL BE GOVERNED BY AND
CONSTRUED IN ACCORDANCE WITH THE LAWS OF THE STATE OF CALIFORNIA.

DISHONORED ITEM FEE.  Borrower will pay a fee to the Lender of $25.00 if
Borrower makes a payment on Borrower's loan and the check or preauthorized
charge with which Borrower pays is later dishonored.

RIGHT OF SETOFF.  Borrower grants to Lender a contractual security interest in,
and hereby assigns, conveys, delivers, pledges, and transfers to Lender all
Borrower's right, title and interest in and to, Borrower's accounts with Lender
(whether checking, savings, or some other account), including without
limitation all accounts held jointly with someone else and all accounts
Borrower may open in the future, excluding however all IRA and Keough accounts,
and all trust accounts for which the grant of a security interest
would be prohibited by law. Borrower authorizes Lender, to the extent permitted
by applicable law, to charge or setoff all sums owing on this Note against any
and all such accounts.

LINE OF CREDIT.  This Note evidences a revolving line of credit. Advances under
this Note may be requested orally by Borrower or by an authorized person. All
oral requests shall be confirmed in writing on the day of the request. All
communications, instructions, or directions by telephone or otherwise to Lender

credited to any of Borrower's accounts with Lender. The unpaid principal
balance owing on this Note at any time may be evidenced by endorsements on this
Note or by Lender's internal records, including daily computer print-outs.

agreement that Borrower or any guarantor has with Lender, including any
agreement made in connection with the signing of this Note; (b) Borrower or any

Mr. Michael Christian, SVP
WebSideStory, Inc.
10182 Telesis Court
San Diego, CA 92121

Dear Mr. Christian:

Based on our discussions concerning the financing needs of WebSideStory, Inc.
("Borrower"), and based upon our preliminary review of the information provided
to date, Imperial Bank ("IB" or "Bank") is pleased to propose the following
financing arrangement. The matters outlined herein constitute a proposal as to
certain terms and conditions under which we may provide financing. It is
intended to be used as a vehicle for continued discussions and further due
diligence, and does not constitute a commitment on behalf of IB at this time.
Nevertheless, subject to the qualifications listed below and the satisfactory
completion of our due diligence, we believe we should be in a position to offer
you a financing package structured along the following lines:

1.   CREDIT FACILITY - REVOLVING EQUIPMENT LINE OF CREDIT

     1.1  Amount: Up to $3,000,000.

     1.2  Availability: Up to 100% for general corporate purposes and to
          finance capital equipment expenditures.

     1.3  Maturity: Up to 12 months from issuance.

     1.4  Amortization: Capital equipment financing shall be available up to 12
          months from the date of commitment, with interest only payable. At the
          end of the 12 months the outstanding equipment balance will convert
          to a 36-month term loan with equal principal payments, plus interest.
          (Equipment draws to include 100% of invoice value excluding soft
          costs, freight, and sales tax).

     1.5  Pricing: Interest shall be payable monthly at the Bank's Prime Rate
          plus 0.25%.

     1.6  Documentation Fee, Costs and Expenses: In addition to any other
          amounts due, or to become due, concurrently with the execution hereof,
          Borrower agrees to pay to Bank a documentation fee in the amount of
          $500, and all other reasonable costs and expenses incurred by the Bank
          in the preparation of this Agreement and any other Loan Documents.

     1.7  Collateral: First position security interest evidenced by a UCC-1
          filing on all corporate assets of Borrower, including specific filings
          on intellectual property.
<PAGE>   26
     1.8  Covenants: Minimum liquidity (defined as unrestricted cash and cash
          equivalents plus eligible accounts receivable), measured monthly, the
          greater of 1) 1.50 times current liabilities and all Bank debt, or 2)
          three months cash burn.

2. GENERAL CONDITIONS

The extensions of credit would necessarily be subject to the fulfillment of a
number of conditions, including, but not limited to, the following:

     2.1  The execution and delivery by the Borrower to IB of such agreements,
          documents, instruments, financing statements, consents, evidences of
          corporate authority, certificates, insurance certificates, opinions of
          counsel, and other such writings to confirm and effectuate the lending
          transaction as may be required by IB and its counsel in form and
          content acceptable to IB.

     2.2. No material adverse change in the business, operations, profits, or
          prospects of Borrower or in the condition of the assets of Borrower
          prior to funding.

     2.3  Negotiation and execution of a satisfactory loan agreement.

     2.4  Borrower agrees to maintain all substantive depository accounts with
          IB.

     2.5  IB's final credit approval and issuance of formal commitment.

     2.6  Borrower to deliver to Bank a five-year warrant to purchase $200,000
          worth of common stock at $2.50 per share. In the event the Borrower
          completes an IPO, the Bank will agree to exercise this warrant, no
          later than, one year from the conclusion of the IPO lock out period.

3. REPORTING REQUIREMENTS

     3.1  Company prepared monthly financial statements within 30 days of month
          end.

     3.2  Detailed schedule of equipment purchases and other expenses
          associated with each drawdown.

     3.3  Annual audited financial statements from independent CPA's
          satisfactory to IB within 120 days of fiscal year-end.

     3.4  A letter will accompany each delivery of interim financial statements
          from Borrower, signed by its Chief Financial Officer, attesting to
          compliance or detailing non-compliance with all material covenants in
          the loan agreements.

     3.5  Access to all Company Board of Directors' minutes upon request by
          Bank.

CONFIDENTIALITY

This letter is provided solely for your information and is delivered to you with
the understanding that neither it, nor its substance, shall be disclosed to any
third person, except those who are in a confidential relationship to you, or
where the same is required by law.

This letter is meant to be a working document, outlining the general terms and
conditions under which Imperial Bank would be willing to consider a financing
arrangement for WebSideStory, Inc. It is not meant to be a comprehensive list
of terms and conditions that may apply to any future commitment, any credit
agreement, or other document that may be entered into by and between IB and
Borrower. Rather, it is intended only to outline certain basic points of
business understanding around which further discussions may take place.

As a result of further analysis and investigation by us, or by reason of
information of which we are not now aware, impediments to closing may be
discovered. We may require that the arrangement be restructured or otherwise
modified to make allowances for such impediments, or the impediments may be so
serious as to affect the closing of these financial arrangements.

We hope this proposal is acceptable to you and request that you execute the
enclosed copy of this letter and return it to us prior to March 24, 2000, at
which time this proposal will expire. Imperial Bank looks forward to assisting
you in achieving your goals of growth and profitability. Please do not hesitate
to contact us if you have any questions regarding this proposal.

Sincerely,

IMPERIAL BANK
