Section 5 – Corporate Governance and Management

On January 30, 2008, the Board of Directors (the “Board”) of 3PAR Inc. (the “Company’) approved the issuance of stock options under the Company’s 2007 Equity Incentive Plan (the “Plan”) to the following directors of the Company:

The stock options are being granted to the directors identified above in order to align their compensation as members of the Board with the other non-employee members of the Board. In addition to the stock option to purchase up to 35,000 shares of common stock issued to each of Messrs. Fong, Siegel and Wei for their respective service as a member of the Board, Mr. Fong is also receiving a stock option to purchase up to 16,000 shares of common stock for his service as the chairman of the compensation committee of the Board.

Each of the stock options will be granted on February 5, 2008, the first day that the Company’s trading window opens under the Company’s insider trading policy, and will have an exercise price per share equal to the greater of (i) $14.00, the initial public offering price of the Company’s common stock and (ii) the closing sales price of the Company’s common stock on February 5, 2008 as quoted by NYSE Arca. The stock options will vest and become exercisable in 48 equal monthly installments beginning with the first monthly anniversary of November 15, 2007.

In the event that Messrs. Fong, Siegel or Wei is no longer serving as a member of the Board following the next annual meeting of stockholders at which such director stands for reelection or otherwise resigns as a member of the Board prior to the end of the four-year vesting period for such director’s stock option, all of the unvested shares subject to the stock option will be cancelled and returned to the Plan. Messrs. Fong and Siegel are each Class I directors and will stand for reelection at the 2008 annual meeting of stockholders. Mr. Wei is a Class II director and will stand for reelection at the 2009 annual meeting of stockholders. Provided that Messrs. Fong, Siegel and Wei are reelected at the applicable annual meeting of stockholders at which they stand for reelection, they will be eligible to receive additional automatic annual stock option awards as provided by the terms and conditions of the Plan.
