Explanation of Responses:

( 1 )Each share of Class B common stock beneficially owned by the Reporting Persons is convertible into one share of Class A common stock at any time, at the holder's option, and has no expiration date. ( 2 )The shares of Class B common stock are owned by Dell Marketing L.P. ("DMLP"). DMLP's sole general partner is Dell Marketing GP L.L.C., which is wholly owned by Dell Marketing Corporation, which in turn is indirectly wholly owned by Denali Holding Inc. ("Denali"). Denali is owned by investors including Silver Lake Partners III, L.P., Silver Lake Technology Investors III, L.P., Silver Lake Partners IV, L.P., Silver Lake Technology Investors IV, L.P. and SLP Denali Co-Invest, L.P. (collectively, the "Silver Lake Funds") and Michael S. Dell, and the Silver Lake Funds have the right, under an agreement with Denali and other Denali stockholders, to approve the sale by Denali or specified subsidiaries of Denali of any shares of common stock of the Issuer held by them. ( 3 )Silver Lake Group, L.L.C. is the managing member of (i) SLTA III (GP), L.L.C. ("SLTA III"), which is the general partner of Silver Lake Technology Associates III, L.P., which is the general partner of Silver Lake Partners III, L.P. and Silver Lake Technology Investors III, L.P. and the managing member of SLP Denali Co-Invest GP, L.L.C., which is the general partner of SLP Denali Co-Invest, L.P. and (ii) SLTA IV (GP), L.L.C. ("SLTA IV"), which is the general partner of Silver Lake Technology Associates IV, L.P., which is the general partner of Silver Lake Partners IV, L.P. and Silver Lake Technology Investors IV, L.P. Egon Durban, who serves as a director of the Issuer, also serves as a Managing Partner and Managing Director of Silver Lake Group, L.L.C. and as a member of the investment committees of SLTA III and SLTA IV, and may be deemed to share voting and dispositive power with respect to any securities beneficially owned by Silver Lake Group, L.L.C. ( 4 )As a result of the relationships and contractual provisions described in footnotes (2) and (3) above, each of the Reporting Persons may be deemed to beneficially own securities of the Issuer held by Dell Marketing L.P. Pursuant to Rule 16a-1(a)(4) under the Securities Exchange Act of 1934, as amended (the "Exchange Act"), this filing shall not be deemed an admission that the Reporting Persons are subject to Section 16 of the Exchange Act or, for purposes of Section 16 of the Exchange Act or otherwise, the beneficial owners of any equity securities in excess of their respective pecuniary interests, and each Reporting Person disclaims beneficial ownership of the securities reported herein, except to the extent of such Reporting Person's pecuniary interest therein, if any.

Remarks: Because no more than 10 reporting persons can file any one Form 3 through the Securities and Exchange Commission's EDGAR system, Silver Lake Partners IV, L.P., Silver Lake Technology Investors IV, L.P., Siler Lake Technology Associates IV, L.P., SLTA IV (GP), L.L.C. and Silver Lake Group, L.L.C. have filed a separate Form 3. Michael S. Dell, DMLP, Dell Marketing GP L.L.C. and Denali have also separately filed a Form 3 reporting beneficial ownership of the securities reported herein. The Reporting Persons are jointly filing this Form 3 pursuant to Rule 16a-3(j) under the Exchange Act.

Reminder: Report on a separate line for each class of securities beneficially owned directly or indirectly.
