Source and Amount of Funds or Other Consideration
   
 
The total purchase price for the 2,550,868 shares of Common Stock beneficially owned by Discovery Group and Messrs. Donoghue and Murphy as of August 10, 2012 was approximately $14,955,554 and the total purchase price for the 2,211,885 shares of Common Stock beneficially owned by Discovery Equity Partners was approximately $12,968,679.  The source of such funds was the assets of Discovery Equity Partners and another private investment partnership (collectively, the “Partnerships”) over which Discovery Group exercises discretionary investment management authority, including proceeds of margin loans under margin loan facilities maintained in the ordinary course of business by the Partnerships with a broker on customary terms and conditions.  The Partnerships are the legal owner of all of the Common Stock beneficially owned by Discovery Group and Messrs. Donoghue and Murphy.
 
 
 

 
 
Item 4.
Purpose of Transaction
   
 
The Reporting Persons acquired beneficial ownership of the shares of Common Stock reported herein as part of their investment activities on behalf of the Partnerships.  The Reporting Persons acquired the shares of Common Stock reported herein because they believe that the trading prices of the Common Stock do not adequately reflect the potential value of the Company’s underlying business and assets.
 
The Reporting Persons intend to review and evaluate their investment in the Common Stock on an ongoing basis and may, depending upon their evaluation of the business and prospects of the Company, or such other considerations as they may deem relevant, determine to increase, decrease, or dispose of their holdings of Common Stock.  As a part of such review and evaluation, the Reporting Persons may hold additional discussions with the Company’s management and directors, other shareholders and other interested parties.
 
Except as otherwise described in this Item 4, the Reporting Persons do not have present plans or proposals that relate to or would result in any of the following (although the Reporting Persons reserve the right to develop such plans or proposals or any other plans relating to the Company and to take action with respect thereto):  (i) the acquisition by any person of additional securities of the Company, or the disposition of securities of the Company; (ii) an extraordinary corporate transaction, such as a merger, reorganization, or liquidation, involving the Company or any of its subsidiaries; (iii) a sale or transfer of a material amount of assets of the Company or any of its subsidiaries; (iv) any change in the present board of directors or management of the Company, including any plans or proposals to change the number or term of directors or to fill any existing vacancies on the board; (v) any material change in the present capitalization or dividend policy of the Company; (vi) any other material change in the Company’s business or corporate structure; (vii) changes in the Company’s certificate of incorporation, bylaws, or instruments corresponding thereto or other actions that may impede the acquisition of control of the Company by any person; (viii) causing a class of securities of the Company to be delisted from a national securities exchange or to cease to be authorized to be quoted in an inter-dealer quotation system of a registered national securities association; (ix) a class of equity securities of the Company becoming eligible for termination of registration pursuant to Section 12(g)(4) of the Securities Exchange Act of 1934, as amended; or (x) any action similar to any of those enumerated above.
   
Item 5.
Interest in Securities of the Issuer
   
 
The information concerning percentages of ownership set forth below is based on 33,787,180 shares of Common Stock reported outstanding as of August 7, 2012 in the Company’s Quarterly Report on Form 10-Q for the quarter ended June 30, 2012.
 
Discovery Equity Partners beneficially owns 2,211,885 shares of Common Stock as of August 10, 2012, which represents 6.5% of the outstanding Common Stock.
 
Discovery Group beneficially owns 2,550,868 shares of Common Stock as of August 10, 2012, which represents 7.5% of the outstanding Common Stock.
 
Mr. Donoghue beneficially owns 2,550,868 shares of Common Stock as of August 10, 2012, which represents 7.5% of the outstanding Common Stock.
 
Mr. Murphy beneficially owns 2,550,868 shares of Common Stock as of August 10, 2012, which represents 7.5% of the outstanding Common Stock.
 
 
 

 
 
 
Discovery Group is the sole general partner of Discovery Equity Partners and has sole discretionary investment authority with respect to the other Partnership’s investment in the Common Stock.  Messrs. Donoghue and Murphy are the sole managing members of Discovery Group.  As a consequence, Discovery Group and Messrs. Donoghue and Murphy may be deemed to share beneficial ownership of all of the shares of Common Stock owned by both of the Partnerships, while Discovery Equity Partners shares beneficial ownership with Discovery Group and Messrs. Donoghue and Murphy of only the shares of Common Stock owned by it.
 
The transactions in Common Stock effected by the Reporting Persons during the past 60 days are set out in Exhibit 1 hereto.
 
No person other than the Partnerships is known to any Reporting Person to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, any of the shares of Common Stock reported herein.
   
Item 6.
Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer
