Explanation of Responses:

* If the form is filed by more than one reporting person, see Instruction 5(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) The shares of each series of preferred stock are currently convertible at any time, at the Reporting Person's election, into common stock of Hortonworks, Inc. (the "Issuer") on a 1-for-2 basis (one common for every two preferred); the number of underlying common shares is shown in the table above (subject to adjustment for certain dilutive issuances, splits, and combinations). The preferred shares have no expiration date, and will automatically convert into shares of common stock upon the closing of the Issuer's initial public offering.
(2) These warrants become exercisable upon the occurrence of certain corporate transactions, including the closing of the Issuer's initial public offering.
(3) These warrants currently represent the right to buy 6,500,000 shares of the Issuer's Series A Preferred Stock at an exercise price of $0.005 per share. Upon the closing of the Issuer's initial public offering, the Series A Preferred Stock will convert to common stock of the Issuer on a 1-for-2 basis and, therefore, these warrants will become exercisable at any time, at the Reporting Person's election, for 3,250,000 shares of common stock at an exercise price of $0.01 per share.
