Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 4(b)(v).
** Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1) On August 11, 2009, pursuant to an underwriting agreement dated August 5, 2009, among STEC, Inc. (the "Company"), the selling shareholders named therein (Manouch Moshayedi and Mark Moshayedi, both officers and directors of the Company) (the "Selling Shareholders"), and J.P. Morgan Securities Inc. and Deutsche Bank Securities Inc., as representatives of the several underwriters named therein (the "Underwriters"), the Selling Shareholders sold 9,000,000 of their outstanding shares of the Company's common stock to the Underwriters at a per share price of $29.76 (for aggregate proceeds, before expenses, of $267,840,000).
(2) These shares were owned directly by the M. and S. Moshayedi Investment Trust, dated 11/16/95, and Manouch Moshayedi is an indirect beneficiary of this trust. The reporting person disclaims beneficial ownership of these securities except to the extent of his pecuniary interest therein.
(3) The shares were owned by the reporting person's children. The reporting person disclaims beneficial ownership of these securities held by his children except to the extent of his pecuniary interest therein.
(4) These shares are owned directly by the M. and S. Moshayedi Revocable Trust, dated 11/16/95, and indirectly by Manouch Moshayedi as trustee of this trust. The reporting person disclaims beneficial ownership of these securities except to the extent of his pecuniary interest therein.
(5) Due to the sale described in footnote (1) above and corresponding footnote (4) above, the M. and S. Revocable Trust, dated 11/16/95 is no longer a 10% beneficial owner of the Company's common stock, and thereby is no longer subject to Section 16. The checked box in the top left corner of this Form 4 relates solely to the M. and S. Moshayedi Revocable Trust, dated 11/16/95. Manouch Moshayedi remains subject to Section 16.
(6) Under the Company's 2000 Stock Incentive Plan and IRS rules, incentive stock options granted to a holder of 10% of more of the Company's common stock must have an exercise price per share not less than 110% of the fair market value per share of the common stock on the grant date and a term of not more than 5 years.
(7) This option shall vest and become exercisable in four equal annual installments commencing on May 7, 2009.
(8) This option shall vest and become exercisable in four equal annual installments commencing on May 14, 2010.
