                            NON-COMPETITION AGREEMENT

          This Non-Competition Agreement (this "Agreement") is being executed
and delivered as of February 1, 2006 by and between David Scherer ("Unitholder")
and WebSideStory, Inc., a Delaware corporation ("Parent").

          WHEREAS, Visual Sciences, LLC, a Delaware limited liability company
(the "Company"), Parent and VS Acquisition, LLC, a Delaware limited liability
company and a wholly owned subsidiary of Parent ("Merger Sub"), have entered
into an Agreement and Plan of Merger (the "Merger Agreement") pursuant to which
the Company will merge with and into Merger Sub (the "Transaction").

          WHEREAS, goodwill was a material consideration in Parent's decision to
enter into the Transaction. If Unitholder were to compete with the business of
Parent and the Company and Merger Sub subsequent to the consummation of the
Transaction, such competition would materially and adversely affect the value of
the business acquired by Parent in the Transaction.

          WHEREAS, in connection with the Transaction and to more fully secure
unto Parent the benefits of the Transaction, Parent has requested that
Unitholder enter into this Agreement, and Unitholder has agreed to enter into
this Agreement.

          NOW, THEREFORE, in consideration of the foregoing and the respective
representations, warranties, covenants and agreements set forth in this
Agreement and intending to be legally bound hereby, the parties hereto agree as
follows:

     1. ACKNOWLEDGMENTS BY UNITHOLDER. Unitholder acknowledges that the promises
and restrictive covenants that Unitholder is providing in this Agreement are
reasonable and necessary to the protection of Parent's business and Parent's
legitimate interests in the Transaction (including the Company's goodwill)
pursuant to the Merger Agreement. Unitholder acknowledges that, in connection
with the consummation of the Transaction, all of Unitholder's Units in the
Company will be converted into Parent Common Stock, Senior Notes, Parent
warrants and cash. Unitholder further acknowledges that he will be eligible to
receive additional stock options from Parent, and that goodwill was a material
consideration in Parent's decision to enter into the Transaction. Unitholder
acknowledges that if Unitholder were to compete with the business of the Company
subsequent to the consummation of the Transaction, such competition could
materially and adversely affect the value of the business acquired by Parent in
the Transaction.

     2. NON-COMPETITION. During the period commencing at the Effective Time and
ending on twenty-four (24) months from the Effective Time (the "Restrictive
Period"), Unitholder shall not be or become an officer, director, Unitholder,
owner, affiliate, salesperson, co-owner, partner, trustee, promoter, technician,
engineer, analyst, employee, agent, representative, supplier, investor or
lender, consultant, advisor or manager of or to, or otherwise acquire or hold
any interest in any person or entity that competes directly with the Company
Business (as defined below) as conducted by the Company on or during the six (6)
months preceding the Effective Time, which for purposes of this Agreement shall
mean and be limited to

<PAGE>

the business of developing and providing software or enabling services for use
by businesses to conduct web site and/or interactive telephone system usage
analytics (collectively, the "Company Business"); provided, however, that
nothing in this Section 2 shall prevent Unitholder from owning as a passive
investment less than one percent (1%) of the outstanding shares of the capital
stock of a publicly-held corporation if (A) such shares are actively traded on
an established national securities market in the United States and (B)
Unitholder is not otherwise associated directly or indirectly with such
corporation or any affiliate of such corporation.

     3. NON-SOLICITATION. During the Restrictive Period, Unitholder shall not,
directly or indirectly, solicit to employ (other than for the benefit of the
Company) any person who is at the time of such solicitation known by Unitholder
to be an employee of Parent or any of its Subsidiaries (including the Company
and its successors) without obtaining the prior written consent of Parent (it
being understood that any newspaper or other public solicitation not directed
specifically to such person shall not be deemed to be a solicitation for
purposes of this provision).

     4. INDEPENDENCE OF OBLIGATIONS. The covenants and obligations of Unitholder
set forth in this Agreement shall be construed as independent of any other
agreement or arrangement between Unitholder, on the one hand, and Parent, on the
other hand.

     5. SPECIFIC PERFORMANCE. Unitholder agrees that in the event of any breach
or threatened breach by Unitholder of any covenant, obligation or other
provision contained in this Agreement, Parent shall be entitled (in addition to
any other remedy that may be available to it) to the extent permitted by
Applicable Law to (a) a decree or order of specific performance to enforce the
observance and performance of such covenant, obligation or other provision and
(b) an injunction restraining such breach or threatened breach.

     6. NON-EXCLUSIVITY. The rights and remedies of Parent hereunder are not
exclusive of or limited by any other rights or remedies which Parent may have,
whether at law, in equity, by contract or otherwise, all of which shall be
cumulative (and not alternative). Without limiting the generality of the
foregoing, the rights and remedies of Parent hereunder, and the obligations and
liabilities of Unitholder hereunder, are in addition to their respective rights,
remedies, obligations and liabilities under the law of unfair competition,
misappropriation of trade secrets and the like. This Agreement does not limit
Unitholder's obligations or the rights of Parent under the terms of (a) the
Merger Agreement or (b) the terms of any other agreement executed by Unitholder
and Parent.

     7. NOTICES. Any notice or other communication required or permitted to be
delivered to Unitholder or Parent under this Agreement shall be in writing and
shall be deemed properly delivered, given and received if (a) delivered in
person, (b) transmitted by telecopy (with written confirmation), (c) mailed by
certified or registered mail (return receipt requested) (in which case such
notice shall be deemed given on the third (3rd) day after such mailing, but only
if deposited at a U.S. Postal Service office in California) or (d) delivered by
an express courier (with written confirmation) to the parties at the following
addresses (or at such other address for a party as shall be specified by like

representatives, executors, administrators, estate, heirs, successors and

and Plan of Merger dated as of February 1, 2006 by and among the Company, VS
Acquisition, LLC, Visual Sciences, LLC and Ned Scherer (the "Merger Agreement")
as part of the consideration payable to the Holder pursuant to the Merger

                                    ARTICLE I

compounded daily. Interest on this Note shall be computed on the basis of a year
of 365 days and paid for the actual number of days elapsed as provided herein.

demand notice. Concurrently with the payment in full of this Note, the Holder
shall surrender this Note to the Company for cancellation.

          Section 1.4 Mandatory Prepayment. In the event the Company incurs any
Indebtedness (other than Permitted Indebtedness) which ranks senior to or pari

this Note, unless the Holder consents to the incurrence of such Indebtedness,
the Company shall prepay in full the outstanding principal amount of this Note
and any and all accrued but unpaid interest thereon prior to or concurrently
with the closing of the transactions under which the evidences of Indebtedness
are issued (such date, the "Mandatory Prepayment Date"). On the Mandatory

than 12:00 p.m. California time on the date on which such payment shall become
due (each such payment made after such time on such due date to be deemed to
have been made on the next succeeding Business Day). If the due date of any
payment in respect of this Note would otherwise fall on a day that is not a
Business Day, such due date shall be instead the next succeeding Business Day.
Payments shall be credited first to the accrued but unpaid interest under this
Note and the remainder applied to outstanding principal under this Note.

amount, in lieu of such lost, stolen, destroyed or mutilated Note.

          Section 2.3 Registration, etc. The Company shall maintain at its

the name and address of the registered Holder thereof, to which notices are to
be sent and the address to which payments are to be made as designated by the

of all transfers, exchanges and replacements of the Note. The Company shall
record on such register any and all transfers of the Note by or for the
registered Holder, in form reasonably satisfactory to the Company, in order to

Company's register on the date of execution thereof by the Company. The

               (iii) The Holder further understands that this Note must be held
indefinitely unless subsequently registered under the Securities Act and
qualified under any applicable state securities laws, or unless exemptions from

Securities Act or an exemption therefrom.
