	File No. 1-33475

Ladies and Gentlemen:

On behalf of Discovery Equity Partners, L.P., Discovery Group I, LLC, Daniel J. Donoghue and Michael R. Murphy (collectively, “Discovery”), we are filing on behalf of Discovery a revised preliminary proxy statement, dated February 10, 2009 (the “Revised Preliminary Proxy Statement”). The Revised Preliminary proxy statement contains the revisions contemplated by our response to Comment No. 2 contained in your letter to Patrick J. Maloney of this firm, dated February 2, 2009 (the “Comment Letter”), commenting on the revised preliminary proxy statement of Discovery that was filed with the Commission on January 28, 2009. Capitalized terms used but not defined herein have the meanings ascribed to them in the Revised Preliminary Proxy Statement.

The revisions set forth in the Revised Preliminary Proxy Statement separate the Stockholder Proposal into two separate and distinct proposals, one relating to the Company’s Rights Plan and the other relating to the ability of Company stockholders to call special meetings.

In connection with this letter, please also find the requisite filing persons statement relating to the Revised Preliminary Proxy Statement attached hereto as Annex A.

Discovery intends to commence mailing its proxy materials to stockholders as soon as possible this week and will file definitive proxy materials at that time.

We appreciate your assistance with this matter. If you have any questions regarding this letter or the attachment or wish to discuss them, please feel free to contact me at (312) 807-4265.

	Very truly yours,

	/s/ Patrick J. Maloney
