CUSIP NO. 390607109

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:

On December 27, 2016, Privet Fund and Privet Fund Management (collectively, “Privet”) entered into an agreement (the “Agreement”) with the Issuer. Pursuant to the Agreement, the Issuer agreed to increase the size of its Board of Directors (the “Board”) from seven to eight members and to appoint Ryan Levenson to fill the resulting vacancy, with a term expiring at the 2017 annual meeting of shareholders (the “2017 Annual Meeting”). Mr. Levenson was also appointed to the Nominating and Corporate Governance Committee of the Board. Concurrent with the 2017 Annual Meeting, the size of the class of directors of the Board with a term expiring at such meeting will automatically decrease from three to two members.  In addition, subject to certain exceptions, the Issuer has agreed to include Mr. Levenson on the Issuer’s slate of nominees for the election of directors at the 2017 Annual Meeting. The Issuer has also agreed to use its reasonable best efforts to appoint a new independent director within the next six months.

Pursuant to the Agreement, during the Standstill Period (as defined below), Privet is subject to certain standstill restrictions that, among other things, prohibit Privet from acquiring more than 14.99% of the Issuer’s outstanding Shares. The “Standstill Period” means the period from the date of the Agreement until (x) if Mr. Levenson is not elected as a director at the 2017 Annual Meeting, six months following the date of the 2017 Annual Meeting or (y) if Mr. Levenson is elected to the Board at the 2017 Annual Meeting, three months following the date on which Mr. Levenson is no longer a member of the Board (in each case, subject to earlier termination in the event of an uncured material breach of the Agreement by the Issuer).

During the Standstill Period, Privet also agreed that it and its affiliates will cause all of their Shares and other voteable securities to be present for quorum purposes and to be voted at any meeting of shareholders (and to consent in connection with any action by consent in lieu of a meeting) (i) in favor of each director nominated and recommended by the Board for election at any such meeting, (ii) against any shareholder nominations for director which are not approved and recommended by the Board for election at any such meeting and against any proposals or resolutions to remove any member of the Board and (iii) in accordance with the recommendations of the Board on all other proposals of the Board set forth in the Issuer’s proxy statement; provided, however, in the event that Institutional Shareholder Services Inc. (“ISS”) recommends otherwise with respect to any proposals (other than the election or removal of directors), Privet shall be permitted to vote in accordance with ISS recommendation; provided, further, that if a proposal with respect to any Extraordinary Matter (as defined in the Agreement) is presented, Privet may vote in its sole discretion with respect to such matter.

The foregoing description of the Agreement is qualified in its entirety by reference to the Agreement, which is attached as Exhibit 99.1 hereto and is incorporated herein by reference.

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

Item 6 is hereby amended to add the following:

On December 27, 2016, Privet and the Issuer entered into the Agreement as defined and described in Item 4 above and attached as Exhibit 99.1 hereto.
