CUSIP NO. 379887201

The following constitutes Amendment No. 1 to the Schedule 13D filed by the undersigned (“Amendment No. 1”). This Amendment No. 1 amends the Schedule 13D as specifically set forth herein.

Item 4.
Purpose of Transaction.

Item 4 is hereby amended to add the following:

The Reporting Persons purchased the shares of Common Stock based on the Reporting Persons’ belief that the shares of Common Stock, when purchased, were undervalued and represented an attractive investment opportunity.
 
No Reporting Person has any present plan or proposal which would relate to or result in any of the matters set forth in subparagraphs (a) - (j) of Item 4 of Schedule 13D except as set forth herein or such as would occur upon or in connection with completion of, or following, any of the actions discussed herein.  The Reporting Persons intend to review their investment in the Issuer on a continuing basis.  Depending on various factors including, without limitation, the Issuer’s financial position and investment strategy, the price levels of the shares of Common Stock, conditions in the securities markets and general economic and industry conditions, the Reporting Persons may in the future take such actions with respect to their investment in the Issuer as they deem appropriate.

After negotiations with the Issuer regarding matters relating to the composition of the Board of Directors of the Issuer (the “Board”) and the 2014 annual meeting of stockholders of the Issuer (the “2014 Annual Meeting”), the Reporting Persons entered into a letter agreement with the Issuer on April 4, 2014 (the “Letter Agreement”).  Pursuant to the terms of the Letter Agreement, among other things, the Board has appointed James H. Cohen and Patrick Lombardi (together, the “New Directors”) as members of the Board to fill the vacancies resulting from the resignations of Jon DeLuca and Grant Dawson as directors of the Issuer, the Issuer will nominate, recommend and support the New Directors as two of five total nominees (the “Issuer Slate”) to stand for election as directors of the Issuer at the 2014 Annual Meeting and the Issuer will reimburse certain fees and expenses incurred by the Reporting Persons in connection with matters related to the 2014 Annual Meeting and the negotiation and execution of the Letter Agreement.  The Letter Agreement also provides that the Reporting Persons will vote for the election of the Issuer Slate at the 2014 Annual Meeting and abide by certain standstill obligations through the conclusion of the 2014 Annual Meeting.

The foregoing description of the terms and conditions of the Letter Agreement does not purport to be complete and is qualified in its entirety by reference to the full text of the Letter Agreement, which is attached hereto as Exhibit 99.1 and incorporated herein by reference.

Item 5.
Interest in Securities of the Issuer.

Items 5(a) - (c) are hereby amended and restated to read as follows:

The aggregate percentage of Common Stock reported owned by each person named herein is based upon 35,167,040 shares of Common Stock outstanding, as of March 3, 2014, which is the total number of shares of Common Stock outstanding as reported in the Issuer’s Annual Report on Form 10-K filed with the Securities and Exchange Commission on March 6, 2014.

(a)      As of the date hereof, GP Investment directly owned 15,276,138 shares of Common Stock, representing approximately 43.4% of the shares of Common Stock outstanding. By virtue of the relationships described in further detail in Item 2, each of MSCC, Robert M. Shuford, Brian Pessin and Sandra and Norman Pessin JTWROS may be deemed to beneficially own the shares of Common Stock owned directly by GP Investment.  Each of MSCC, Robert M. Shuford, Brian Pessin and Sandra and Norman Pessin JTWROS disclaims beneficial ownership of such shares.

As of the date hereof, MSCC directly owned 7,345 shares of Common Stock, representing less than 1% of the shares of Common Stock outstanding.  MSCC may be deemed to beneficially own an additional 47,741 and 18,362 shares of Common Stock, representing less than 1% of the shares of Common Stock outstanding, held by Main Street Mezzanine Fund LP and Main Street Capital II, LP, respectively.  Main Street Mezzanine Fund LP and Main Street Capital II, LP are subsidiaries of MSCC.  MSCC disclaims beneficial ownership of such shares.

(b)      GP Investment may be deemed to share with MSCC, Robert M. Shuford, Brian Pessin and Sandra and Norman Pessin JTWROS the power to vote and dispose of the Common Stock directly owned by GP Investment.

MSCC may be deemed to share with Main Street Mezzanine Fund LP and Main Street Capital II, LP, subsidiaries of MSCC, the power to vote and dispose of the Common Stock directly owned by Main Street Mezzanine Fund LP and Main Street Capital II, LP.  MSCC has sole power to vote and dispose of the shares of Common Stock it owns directly.

(c)      None of the Reporting Persons have entered into any transactions in the shares of Common Stock during the past sixty days.

Item 6.
Contracts, Arrangements, Understandings or Relationships with Respect to Securities of the Issuer.

Item 6 is hereby amended to add the following:

On April 4, 2014, the Reporting Persons and the Issuer entered into the Letter Agreement as defined and described in Item 4 above.  The Letter Agreement is attached hereto as Exhibit 99.1 and incorporated herein by reference.
