F1The filing of this Form 4 shall not be construed as an admission that Ancient Art, L.P. ("Ancient Art"), Whitney, L.P. ("Whitney"), Trango II, L.L.C., the general partner of both Ancient Art and Whitney, and Quincy J. Lee, the principal of Trango, 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 Class B Common Stock, $.01 Par Value (the "Common Stock"), of Rush Enterprises, Inc. (the "Issuer") purchased by Teton Capital Partners, L.P. (the "Fund"). Pursuant to Rule 16a-1, Ancient Art, Whitney, Trango and Mr. Lee disclaim such beneficial ownership except to the extent of its or his spective pecuniary interest therein.
