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) The filing of this Form 4 shall not be construed as an admission that Prescott Group Capital Management, L.L.C. ("Prescott Capital") or Phil Frohlich, the manager of Prescott Capital, is or was, for the purposes of Section 16(a) of the Securities Exchange Act of 1934, as amended, or otherwise, the beneficial owner of any of the shares of common stock of Air Transport Services Group, Inc. (the "Common Stock") purchased by Prescott Group Aggressive Small Cap Master Fund, G.P. (the "Master Fund") for the accounts of Prescott Group Aggressive Small Cap, L.P. or Prescott Group Aggressive Small Cap II, L.P. (together, the "Small Cap Funds"). Pursuant to Rule 16a-1, both Prescott Capital and Phil Frohlich disclaim such beneficial ownership.
(2) Prescott Capital holds indirectly 7,189,081 shares of Common Stock of Air Transport Services Group, Inc. through the account of the Master Fund, of which the Prescott Capital is the Investment Manager. The Master Fund holds the shares of Common Stock for the accounts of the Small Cap Funds, of which Prescott Capital is the Investment Manager. Prescott Capital receives a portion of the profits in the way of a capital allocation from, and owns a partnership interest in, the Small Cap Funds. Phil Frohlich reports the shares held indirectly by Prescott Capital because, as the manager of Prescott Capital at the time of purchase, he controlled the disposition and voting of the securities.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.
