		This Amendment No. 3 to Schedule 13D (“ Amendment No. 3 ”) relates to the Common Stock, $0.001 par value per share (the “ Common Stock ”), of Globecomm Systems Inc., a Delaware corporation (the “ Company ”), which has its principal executive offices at 45 Oser Avenue, Hauppauge, NY 11788. This Amendment No. 3 amends and supplements, as set forth below, the information contained in items 1, 3, 4, 5 and 6 of the Schedule 13D filed by the Reporting Persons with respect to the Company on July 23, 2012, as amended by Amendment No. 1 thereto filed by the Reporting Persons on September 26, 2012, and Amendment No. 2 thereto filed by the Reporting Persons on October 9, 2012 (as so amended, the “ Schedule 13D ”). All capitalized terms used herein but not defined herein have the meanings set forth in the Schedule 13D. Except as amended by this Amendment No. 3, all information contained in the Schedule 13D is, after reasonable inquiry and to the best of the Reporting Persons’ knowledge and belief, true, complete and correct as of the date of this Amendment No. 3.

Donoghue and Murphy as of December 28, 2012 was approximately $14,781,975. The source of such funds was the assets of Discovery Equity Partners over which Discovery Group exercises discretionary investment management authority, and proceeds of margin loans under margin loan facilities maintained in the ordinary course of business by Discovery Equity Partners with a broker on customary terms and conditions. Discovery Equity Partners is the legal owner of all of the Common Stock beneficially owned by Discovery Group and Messrs. Donoghue and Murphy.
Item 4.		Purpose of Transaction
		Item 4 of the Schedule 13D is hereby amended by replacing the first paragraph with the following: The Reporting Persons acquired beneficial ownership of the shares of Common Stock reported herein as part of their investment activities on behalf of Discovery Equity Partners.
