This Current Report on Form 8-K is filed by Visual Sciences, Inc., a Delaware corporation formerly known as WebSideStory, Inc. (“Visual Sciences”), in connection with the matters described herein.

Item 1.01. Entry into a Material Definitive Agreement.

     On February 23, 2007, Visual Sciences entered into a Loan and Security Agreement with Silicon Valley Bank, a California corporation (“Silicon Valley Bank”), which was subsequently amended by a First Amendment to Loan and Security Agreement dated September 18, 2007.

     On December 31, 2007, Visual Sciences entered into a Second Amendment to Loan and Security Agreement with Silicon Valley Bank, pursuant to which certain financial covenants in the Loan and Security Agreement were amended with respect to (1) increasing the adjusted quick ratio to be maintained by Visual Sciences on a quarterly basis from 1.0:1.0 to 1.50:1.0 and (2) decreasing the minimum level of earnings before stock-based compensation, taxes, depreciation and amortization (“EBSTDA”) to be maintained by Visual Sciences for each of the fiscal quarters ending December 31, 2007 through December 31, 2008 from $2.5 million to zero; provided, however, that Visual Sciences may incur up to $1.25 million of acquisition-related expenses per quarter, which acquisition-related expenses will be added back into the calculation of EBSTDA for purposes of determining compliance with this covenant.

     These amendments were occasioned by, among other things, expenses incurred in connection with Visual Sciences’ proposed merger with a wholly-owned subsidiary of Omniture, Inc., pursuant to which Visual Sciences will continue as the surviving corporation and a wholly-owned subsidiary of Omniture, Inc.

     Pursuant to the Second Amendment to Loan and Security Agreement, Silicon Valley Bank also ratified and confirmed its previous waiver with respect to the event of default which may have occurred under the Loan and Security Agreement resulting from Visual Sciences’ failure to maintain a minimum level of EBSTDA in the three-month period ended September 30, 2007. In connection with the execution of the Second Amendment to Loan and Security Agreement, Visual Sciences paid Silicon Valley Bank a $12,500 fee and agreed to pay certain fees, costs and expenses incurred by it in connection with the amendment to the agreement.

     Visual Sciences also made certain representations and warranties in the Second Amendment to Loan and Security Agreement that are customary in similar agreements.

     The foregoing description of the Second Amendment to Loan and Security Agreement is only a summary, does not purport to be complete, and is qualified in its entirety by reference to the full text of the Second Amendment to Loan and Security Agreement, which is filed as Exhibit 10.1 to this report and is incorporated herein by reference.
