b. If any of the Work Product may not, by operation of law, be considered work
made for hire by you for WebSideStory, or if ownership of all right, title, and
interest of the intellectual property rights therein will not otherwise vest
exclusively in WebSideStory, you agree to assign, and upon creation thereof

YOU AGREE TO KEEP WEBSIDESTORY CONFIDENTIAL INFORMATION IN STRICT CONFIDENCE.

WEBSIDESTORY CONFIDENTIALITY Your position with WebSideStory requires
considerable responsibility and trust. Relying on your ethical responsibility
and undivided loyalty, WebSideStory expects to entrust you with highly sensitive
confidential, restricted, and proprietary information involving Trade Secrets
(as defined below). It could prove very difficult to isolate these Trade Secrets
from business activities that you might consider pursuing after termination of
your employment, and in some instances, you may not be able to compete with
WebSideStory in certain ways because of the risk that WebSideStory's Trade
Secrets might be compromised. You are legally and ethically responsible for
protecting and preserving WebSideStory's proprietary rights for use only for
WebSideStory's benefit, and these responsibilities may impose unavoidable
limitations on your ability to pursue some kinds of business opportunities that
might interest you during or after your employment.

TRADE SECRETS DEFINED For purposes of this Agreement, a "Trade Secret" is any
information, including, but not limited to, technical or non-technical data,
formulas, patterns, compilations, programs, devices, methods, techniques,
drawings, processes, financial data, employee salaries, financial plans, product
plans, or lists of actual or potential customers or suppliers that: (1) derive
economic value, actual or potential, from not being generally known to, and not
being readily ascertainable by proper means by, other persons who can obtain
economic value from their disclosure or use; and (2) are the subject of efforts
that are reasonable under the circumstances to maintain their secrecy.

RESTRICTIONS ON USE AND DISCLOSURE OF TRADE SECRETS You agree not to use or
disclose any Trade Secrets of WebSideStory during your employment and for so
long afterwards as the pertinent information or data remain Trade Secrets,
regardless of whether the Trade Secrets are in written or tangible form, except
as required to perform any duties for WebSideStory.

SCREENING OF PUBLIC RELEASES OF INFORMATION In addition, and without any
intention of limiting your other obligations under this Agreement in any way,
you should not, during your employment, reveal any non-public information
concerning the technology pertaining to the proprietary products and
manufacturing processes of WebSideStory (particularly technology under current
development or improvement), unless you have obtained written approval from
WebSideStory in advance. In that connection, you should submit to WebSideStory
for review any proposed scientific and technical articles and the text of any
public speeches relating to work done for WebSideStory before they are released
or delivered. WebSideStory has the right to disapprove and prohibit, or delete
any parts of such articles or speeches that might disclose WebSideStory's Trade
Secrets or other confidential information or otherwise be contrary to
WebSideStory's business interests.

UPON YOUR TERMINATION OF EMPLOYMENT WITH WEBSIDESTORY, YOU AGREE TO TURN OVER
ALL NOTES, DATA, DISKETTES, TAPES, REFERENCE ITEMS, SKETCHES OR DRAWINGS,
MEMORANDA, RECORDS, AND THE MATERIALS IN YOUR POSSESSION OR CONTROL WHICH IN ANY
WAY RELATE TO ANY WEBSIDESTORY CONFIDENTIAL INFORMATION.

RETURN OF MATERIALS At the request of WebSideStory and, in any event, upon the
termination of your employment, you must return to WebSideStory and leave at its
disposal all memoranda, notes, records, drawings, manuals, computer programs,
documentation, diskettes, computer tapes, and other documents or media
pertaining to the business of WebSideStory or your specific duties for
WebSideStory, including all copies of such materials. You must also return to
WebSideStory and leave at its disposal all materials involving



                                        3
<PAGE>

any Trade Secrets of WebSideStory. This Section is intended to apply to all
materials made or compiled by you, as well as to all materials furnished to you
by anyone else in connection with your employment. YOU ARE OBLIGATED TO CONTINUE
TO PROTECT WEBSIDESTORY'S CONFIDENTIAL INFORMATION, AFTER YOU LEAVE OUR
EMPLOYMENT.

UNFAIR COMPETITION Employee acknowledges and agrees that the sale or
unauthorized use or disclosure of any of WebSideStory's trade secrets obtained
by Employee during the course of his engagement, including information
concerning WebSideStory's current or any future and proposed work, series or
products, the facts that any such work services, or products are planned, under
consideration, or in production, as well as any descriptions thereof, constitute
unfair competition. Employee promises and agrees not to engage in any unfair
competition with WebSideStory, either during the term of his engagement or at
any time thereafter.

HIRING EMPLOYEES You agree, for a period ending one year after the termination
of your employment with WebSideStory, not to hire or engage, or attempt to hire
or engage, directly or indirectly, any individual who was an employee of
WebSideStory at any time during the one-year period prior to the date of your
termination of employment with WebSideStory, whether for or on behalf of you or
for any entity in which you have a direct or indirect interest, whether as a
proprietor, partner, stockholder, employee , agent, representative, or
otherwise.

IF ANY PART OF THIS AGREEMENT IS NOT LEGAL, THE OTHER LEGAL PARTS WILL REMAIN IN
FORCE.

SEVERABILITY The covenants in this Agreement will be construed as covenants
independent of one another and as obligations distinct from any other contract
between you and WebSideStory. Any claim that you may have against WebSideStory
will not constitute a defense to enforcement by WebSideStory of this Agreement.

SOME OF YOUR OBLIGATIONS WILL SURVIVE THE TERMINATION OF YOUR EMPLOYMENT WITH
WEBSIDESTORY.

SURVIVAL OF OBLIGATIONS The covenants in this Agreement concerning work product,
trade secrets, confidential information, unfair competition and hiring employees
will survive termination of your employment, regardless of who causes the
termination and under what circumstances.

WEBSIDESTORY WILL BE IRREPARABLY HARMED IF YOU BREACH WEBSIDESTORY
CONFIDENTIALITY OR TAKE TRADE SECRETS. TO PROTECT OURSELVES, WE MUST BE ABLE TO
STOP ANY EMPLOYEE IMMEDIATELY WHO MISAPPROPRIATES WEBSIDESTORY CONFIDENTIAL
INFORMATION OR TRADE SECRETS.

SPECIFIC PERFORMANCE AND CONSENT TO INJUNCTIVE RELIEF Irreparable harm will be
presumed if you breach any covenant in this Agreement. The faithful observance
of all covenants in this Agreement is an essential condition to your employment,
and WebSideStory is depending upon absolute compliance. Damages would probably
be very difficult to ascertain if you breached any covenant in this Agreement.
This Agreement is intended to protect the proprietary rights of WebSideStory in
many important ways. Even the threat of any misuse of the technology of
WebSideStory would be extremely harmful, since that technology is essential to
the business of WebSideStory. In light of these facts, you agree that any court
of competent jurisdiction should immediately enjoin any breach of this Agreement
upon the request of WebSideStory. Also, you specifically release WebSideStory
from the requirement of posting any bond in connection with temporary or
interlocutory injunctive relief, to the extent permitted by law.

AL.    SALARY Employee will be paid an annual salary of $160,000.00. Employee's
       salary will be paid in equal installments at regular payroll periods
       (every two weeks). Employee's salary will be reviewed periodically by the
       president of WebSideStory and may be increased or decreased from time to
       time at his sole discretion.

A2.    DEDUCTIONS WebSideStory will deduct from any compensation payable to
       Employee the sums that it is required by law to deduct, including but not
       limited to federal and state withholding taxes, social security taxes and
       state disability insurance.

A3.    BENEFITS Medical coverage is a benefit that WebSideStory provides for its
       employees alone; spouses are excluded from coverage. At your own cost,
       however, we do give you the option to include your spouse in the medical

       premium, we will in turn deduct the premium from your paycheck. Employee
       will be entitled to medical coverage after a period of 30 days.
