Item 5.02 Departure of Directors or Certain Officers; Election of Directors; Appointment of Certain Officers; Compensatory Arrangements of Certain Officers.

(e) Compensatory Arrangements of Certain Officers

On March 22, 2012, the Compensation Committee of the Board of Directors of STEC, Inc. (“STEC”) approved (1) an increase in the annual base salary of Robert M. Saman, STEC’s Chief Legal Officer, General Counsel and Secretary, from $260,000 to $340,000, retroactive to January 1, 2012 and (2) an increase in Mr. Saman’s 2012 target bonus opportunity under STEC’s Executive Cash Incentive Plan (the “ECIP”) from 35% to 50% of his annual base salary.

The 2012 base salaries and 2012 target bonus opportunities under the ECIP for Mr. Mark Moshayedi, STEC’s President, Chief Operating Officer and Chief Technology Officer, and Mr. Cook, STEC’s Chief Financial Officer, were increased by nominal amounts. The 2012 base salary and 2012 target bonus opportunity under the ECIP for Mr. Manouch Moshayedi, STEC’s Chief Executive Officer, were not adjusted.

Consistent with recent prior years, the Compensation Committee determined that a long-term strategy of setting named executive officers’ target total direct compensation (consisting of base salary, target cash incentive compensation and equity compensation) generally in the 50th to 75th percentile range was appropriate to attract and retain executive talent and to incentivize exceptional performance. STEC’s peer group is determined in consultation with Radford, the Compensation Committee’s independent compensation consultant, as disclosed in STEC’s Proxy Statement on Schedule 14A filed on April 1, 2011. In considering the target total direct compensation for Mr. Mark Moshayedi, Mr. Cook and Mr. Saman, the Compensation Committee approved increases to each of the officer’s annual base salary and target bonus opportunity that are consistent with this strategy.

Item 8.01. Other Events.

On March 22, 2012, the independent members of STEC’s Board of Directors, on the recommendation of STEC’s Nominating and Corporate Governance Committee, re-appointed Kevin C. Daly, Ph.D. as STEC’s Lead Independent Director, to serve for another one-year term until STEC’s 2013 Annual Meeting of Shareholders. Duties of the Lead Independent Director include, among other responsibilities, providing STEC’s Chairman of the Board of Directors with input regarding meeting agendas, calling and presiding over executive sessions of the independent directors and acting as a liaison between the independent directors and Chief Executive Officer, who also serves as Chairman. Dr. Daly joined the Board of Directors in May 2010 and currently serves as a member of STEC’s Audit, Compensation and Nominating and Corporate Governance Committees.
