Explanation of Responses:

          (1)  Includes (i) 455 shares of Common Stock owned directly by Mr.
Reimert and (ii) 121,188 shares of Common Stock subject to exercisable options.
Excludes 12,000 shares of Common Stock owned by Mr. Reimert's wife, as to which
Mr. Reimert disclaims beneficial ownership.

          (2)  Does not include 7,139,576 shares of Common Stock (including
exercisable options to buy shares of Common Stock), with respect to Mr. Reimert,
or 7,261,219 shares of Common Stock, with respect to Reimert Family Partners,
Ltd., owned by certain stockholders of Dril-Quip, Inc. (the "Issuer") who are
parties to the Stockholders' Agreement dated October 17, 1997 (the
"Stockholders' Agreement"). Pursuant to the Stockholders' Agreement, certain
stockholders of the Issuer have agreed to vote shares of common stock, par value
$.01 per share, of the Issuer held by each of them for the election of nominees
to the Board of Directors proposed by each of (i) Larry E. Reimert and Reimert
Family Partners, Ltd., (ii) Gary D. Smith and Four Smith's Company, Ltd. and
(iii) J. Mike Walker. The parties to the Stockholders' Agreement may be deemed
to have formed a group pursuant to Rule 13d-5(b)(1) promulgated under the
Securities Exchange Act of 1934, as amended (the "Exchange Act"). Nothing herein
shall constitute an affirmance that any such group exists; however, any such
group could be deemed to have beneficial ownership, for purposes of Section
13(d) and 13(g) of the Exchange Act, of all equity securities of the Issuer
beneficially owned by such parties. Such parties would, as of January 31, 2002,
be deemed to beneficially own an aggregate of 10,394,264 shares of Common Stock,
or approximately 60.1% of the total number of shares reported to be outstanding
in the Issuer's Form 10-Q for the quarter ended September 30, 2001. Each of Mr.
Reimert and Reimert Family Partners, Ltd. disclaims the beneficial ownership of
any Common Stock owned by such other parties.

          (3)  Includes 3,133,045 shares of Common Stock owned directly by
Reimert Family Partners, Ltd., as to which Mr. Reimert, as its managing general
partner, exercises sole voting and dispositive power. Because Mr. Reimert
exercises sole voting and dispositive power with respect to these shares, he may
be deemed to be an indirect beneficial owner of these shares for purposes of
Rule 13d-3.
