Explanation of Responses:

(1) The reporting persons (the "Reporting Persons") are Westcliff Capital Management, LLC ("Westcliff") and Richard S. Spencer III, a manager and the majority member of Westcliff. Each Reporting Person disclaims membership in a group with any non-reporting person within the meaning of Rule 13d-5(b)(i) and Rule 16a-1(a)(1) under the Exchange Act.

(2) All shares are owned directly by investment limited partnerships of which Westcliff is the general partner and investment adviser, and by clients to which Westcliff is investment adviser. Shares held by those investment limited partnerships are owned indirectly by Westcliff and Mr. Spencer as the controlling person of Westcliff. Mr. Spencer and Westcliff disclaim beneficial ownership of such shares except to the extent of their respective pecuniary interest therein. No investment limited partnership or client account of Westcliff owns more than ten percent of the outstanding stock of the Issuer.

(3) Pursuant to the terms of the Common Stock and Warrant Purchase Agreement, dated March 28, 2002 (the "Purchase Agreement") and the First Addendum to the Purchase Agreement, dated as of April 30, 2002 (the "First Addendum"), the Issuer issued these penalty warrants to purchase additional shares of common stock to affiliates of Westcliff and other investors on June 21, 2002, because the Issuer's Form S-3 to register the common shares purchased by such investors pursuant to the Purchase Agreement and First Addendum had not been declared effective by the Securities and Exchange Commission by that date. On September 26, 2002, after the Issuer's Form S-3 was declared effective by the Securities and Exchange Commission, the investors agreed to return the penalty warrants to the Issuer.

In addition to the foregoing, on March 28, 2002, the Issuer granted to Westcliff the right to designate two individuals to serve as directors on the Issuer's board of directors (the "Westcliff Nominees"). If there is a vacancy in the board of directors at any time prior to the next stockholders' meeting of the Issuer at which one or more directors is to be elected, the Issuer and the board have agreed to appoint the Westcliff Nominees to the board and the executive committee of the board as soon as reasonably practicable after such board seat becomes available. The Westcliff Nominees will serve on the board and the executive committee until the next stockholders meeting at which the term of such directors expires. Thereafter, in connection with each stockholders' meeting at which the board seat occupied by one or both of the Westcliff Nominees is up for nomination and election, the Issuer will nominate the person(s) designated by Westcliff for election to the board and recommend to its stockholders that they vote for the Westcliff Nominees. If one or both Westcliff Nominees are elected to the board, the board will appoint the elected Westcliff Nominees to serve on the board's executive committee. The obligations of the Issuer and the board of directors to appoint the Westcliff Nominees, or to nominate the Westcliff Nominees and recommend them for election, to the board terminates immediately when Westcliff and its affiliates hold less than 400,000 shares of the Issuer's common stock. As a result of the right to designate two members of the Issuer's board, Westcliff and Mr. Spencer could be deemed insiders of the Issuer notwithstanding their ownership interest in the Issuer's outstanding common stock. Pursuant to this agreement, Richard S. Spencer III has been appointed to the Issuer's board.
