Section 1 — Registrant’s Business and Operations

Item 1.01. Entry into a Material Definitive Agreement

Employment Agreement

     On January 4, 2005, Informatica Corporation (the “Company”) appointed Paul J. Hoffman as the Company’s executive vice president of worldwide sales. Pursuant to an employment agreement (“Employment Agreement”) between the Company and Mr. Hoffman, Mr. Hoffman will receive an annual base salary of $300,000. Mr. Hoffman will also receive an annualized target commission of $250,000 based on successful achievement of sales quota objectives. In addition, Mr. Hoffman was granted an option to purchase 550,000 shares of the Company’s Common Stock. One quarter of the shares subject to such option grant vests and becomes exercisable one year after the grant date and the remaining shares subject to such option grant vest in equal monthly installments over the following 36-month period, such that the option is fully exercisable four (4) years after its date of grant.

Executive Severance Agreement

     Additionally, on January 4, 2005, the Company and Mr. Hoffman entered into an Executive Severance Agreement (the “Agreement”) which describes the severance terms and conditions for Mr. Hoffman in the event that his employment is terminated in connection with a “Change of Control”.

     Term of Agreement. The Agreement has an initial term of two years. The Agreement provides that the initial term will be automatically extended each year for an additional one year term unless the Company informs the executive officer at least 90 days prior to the date of automatic renewal that it is electing not to extend the term.

     Severance. In the event that the Company terminates the executive officer’s employment without “Cause” or the executive resigns for “Good Reason,” and such termination occurs within the time period beginning on the date three months preceding a Change of Control of the Company and ending on the date 12 months following a Change of Control, the executive officer will receive the following severance package:

     The severance payments, continued benefits, and accelerated vesting will be subject to the executive officer entering into (and not subsequently revoking) a (1) separation agreement and release of claims in a form satisfactory to the Company and the executive officer, (2) a non-compete and non-solicitation agreement that would be in effect during the 12 month period in which the executive officer receives continuing salary from the Company and (3) a non-disparagement agreement.
