Adoption of Rule 10b5-1 Trading Plan

On November 12, 2013, Sohaib Abbasi, the chairman and chief executive officer of Informatica Corporation (“Informatica”) entered into a pre-arranged trading plan for the sale of shares of Informatica’s common stock in accordance with the plan’s specifications (the “10b5-1 Plan”). No sales will occur under the 10b5-1 Plan before January 13, 2014.  The 10b5-1 Plan provides for the same-day exercise and sale on Mr. Abbasi’s behalf of (i) options for 179,885 shares that expire on February 1, 2014, (ii) options for 1,339,104 shares that expire on July 19, 2014, and (iii) options for 400,000 shares that expire on February 1, 2015.  The 10b5-1 Plan was also established as part of Mr. Abbasi’s individual long-term strategies for financial planning, asset diversification and liquidity. Mr. Abbasi’s 10b5-1 Plan was adopted in accordance with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, as well as guidelines previously adopted by Informatica’s Board of Directors for individuals who elect to enter into 10b5-1 trading plans. Mr. Abbasi’s current 10b5-1 trading plan terminates in December 2013.

Mr. Abbasi also expects to exercise and hold options for approximately 210,000 shares (which also expire on February 1, 2014) by the end of 2013.
