(a) This statement is filed by Clinton Group, Inc., a Delaware corporation ("CGI"), Clinton Multistrategy Master Fund, Ltd., a Cayman Islands company ("CMSF"), Clinton Special Opportunities Master Fund, Ltd., a Cayman Islands company ("CSO"), George Hall and Conrad Bringsjord (collectively, the "Reporting Persons").

George Hall is the Chief Investment Officer and President of CGI. Conrad Bringsjord is a managing director and senior portfolio manager of CGI. (d) None of the Reporting Persons nor any of the individuals set forth in Schedule A attached hereto has, during the last five years, been convicted in a criminal proceeding (excluding traffic violations or similar misdemeanors). (e) None of the Reporting Persons nor any of the individuals set forth in Schedule A attached hereto has, during the last five years, been a party to a civil proceeding of a judicial or administrative body of competent jurisdiction and as a result of such proceeding was or is subject to a judgment, decree or final order enjoining future violations of, or prohibiting or mandating activities subject to, federal or state securities laws or finding any violation with respect to such laws. (f) George Hall and Conrad Bringsjord are citizens of the United States of America. The name, citizenship, present principal occupation or employment and business address of each director and executive officer of CGI, CMSF and CSO is set forth in Schedule A attached hereto. To the best of the Reporting Persons' knowledge, except as set forth in this statement on Schedule 13D, none of such individuals owns any Shares. ITEM 3. SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION. Funds for the purchase of the Shares reported herein were derived from available capital of CMSF and CSO. A total of approximately $36,856,532 was paid to acquire such Shares.

- --------------------------- ------------------- CUSIP NO. 398433102 SCHEDULE 13D PAGE 8 OF 12 PAGES - --------------------------- ------------------- ITEM 4. PURPOSE OF TRANSACTION. The Reporting Persons originally acquired Shares for investment in the ordinary course of business because they believed that the Shares, when purchased, were undervalued and represented an attractive investment opportunity. On December 19, 2006, CGI delivered a letter to the Issuer stating its belief that the market price of the Shares fails to reflect the stand-alone value of the Issuer's operating subsidiaries. The letter also indicated CGI's desire to work constructively with the Issuer's management to continue to evaluate multiple strategic alternatives for the Issuer, including, but not limited to, a tax-free spin-off or sale to strategic acquirors of one or more of the Issuer's subsidiaries, or a going-private transaction for the Issuer. A copy of this letter is attached hereto as Exhibit B and is incorporated herein by reference. Except as set forth herein or as would occur upon completion of any of the actions discussed herein, including in any Exhibits hereto, the Reporting Persons have no present plan or proposal that would relate to or result in any of the matters set forth in subparagraphs (a)-(j) of Item 4 of Schedule 13D. The Reporting Persons intend to review their investment in the Issuer on a continuing basis and may engage in discussions with management, the board of directors, other shareholders of the Issuer and other relevant parties concerning the business, operations, management, strategy and future plans of the Issuer. Depending on various factors including, without limitation, the Issuer's financial position and strategic direction, the outcome of the discussions and actions referenced above, actions taken by the board of directors, price levels of the Shares, other investment opportunities available to the Reporting Persons, conditions in the securities market 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 including, without limitation, purchasing additional Shares or selling some or all of their Shares, engaging in short selling of or any hedging or similar transactions with respect to the Shares and/or otherwise changing their intention with respect to any and all matters referred to in Item 4 of Schedule 13D.

- --------------------------- ------------------- CUSIP NO. 398433102 SCHEDULE 13D PAGE 9 OF 12 PAGES - --------------------------- ------------------- ITEM 5. INTEREST IN SECURITIES OF THE ISSUER. (a) As of the close of business on December 19, 2006, the Reporting Persons beneficially owned an aggregate of 1,538,944 Shares, constituting approximately 5.2% of the Shares outstanding. The aggregate percentage of Shares beneficially owned by the Reporting Persons is based upon 29,824,789 Shares outstanding, which is the total number of Shares outstanding as of December 8, 2006 as reported in the Issuer's Annual Report on Form 10-K for the period ended September 30, 2006. (b) By virtue of investment management agreements with each of CMSF and CSO, CGI has the power to vote or direct the voting, and to dispose or direct the disposition, of all of the 1,433,244 Shares held by CMSF and the 105,700 Shares held by CSO. By virtue of his direct and indirect control of CGI, George Hall is deemed to have shared voting power and shared dispositive power with respect to all Shares as to which CGI has voting power or dispositive power. By virtue of his position as managing director and senior portfolio manager of CGI, Conrad Bringsjord is also deemed to have shared voting power and shared dispositive power with respect to all Shares as to which CGI has voting power or dispositive power. Accordingly, CGI, George Hall and Conrad Bringsjord are deemed to have shared voting and shared dispositive power with respect to an aggregate of 1,538,944 Shares. (c) Information concerning transactions in the Shares effected by the Reporting Persons during the past sixty days is set forth in Schedule B hereto and is incorporated herein by reference. Unless otherwise indicated, all of such transactions were effected in the open market. (d) No person other than the Reporting Persons is known to have the right to receive or the power to direct the receipt of dividends from, or the proceeds from the sale of, the Shares. (e) Not applicable. Item 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER. The Reporting Persons may, from time to time, enter into and dispose of cash-settled equity swap or other similar derivative transactions with one or more counterparties that are based upon the value of Shares, which transactions may be significant in amount. The profit, loss and/or return on such contracts may be wholly or partially dependent on the market value of the Shares, the relative value of Shares in comparison to one or more other financial instruments, indexes or securities, a basket or group of securities in which Shares may be included, or a combination of any of the foregoing. In addition to the Shares that they beneficially own without reference to these contracts, the Reporting Persons currently have long economic exposure to 559,200 Shares through such contracts. These contracts do not give the Reporting Persons direct or indirect voting, investment or dispositive control over any securities of the Issuer and do not require the counterparties thereto to acquire, hold, vote or dispose of any securities of the Issuer. Accordingly, the Reporting Persons disclaim any beneficial ownership in any securities that may be referenced in such contracts or that may be held from time to time by any counterparties to such contracts. Except as otherwise set forth herein, the Reporting Persons do not have any contract, arrangement, understanding or relationship with any person with respect to the securities of the Issuer. Item 7.

Mr. Harvey R. Blau
Chairman of the Board and CEO

Griffon Corporation
100 Jericho Quadrangle
Jericho, NY 11753

Dear Mr. Blau:

We greatly  appreciate you and Mr.  Edelstein taking the time to discuss with us
Griffon Corporation  ("Griffon" or the "Company") and its prospects,  and we are
pleased  with  management's  willingness  to  listen  to  shareholder  ideas and
opinions.   Currently,   funds  and  accounts  managed  by  Clinton  Group  Inc.
("Clinton")  beneficially  own in excess of 5% of the outstanding  shares of the
Company.

We have been  impressed  with the  franchise  that  management  has  built,  and
continue to appreciate  management's  eye towards  returning  shareholder  value
through steady share repurchases. We have invested in Griffon because we believe
the  market  price of  Griffon  shares  fails to  reflect  the true value of the
Company's  operating  subsidiaries,  if they were to be valued on a  stand-alone
basis.

Given the apparent  disconnect  between each segment's  intrinsic  value and the
Company's  current  stock  price,  we were  pleased  to  hear on last  quarter's
conference call that management was proactively reviewing strategic alternatives
with  respect  to the  defense  segment.  We hope to  work  constructively  with
management to continue to evaluate multiple strategic  alternatives,  including,
but not limited to, a tax-free spin-off or sale to strategic acquirors of one or
more of Griffon's subsidiaries,  or a going-private transaction for the Company.
Given the market leading positions of Clopay  Corporation's garage door division
and  specialty  films  division,  as  well  as  Telephonics  Corporation's  well
positioned and growing defense segment, we believe any of these initiatives,  or
a combination thereof, would unlock significant value for existing shareholders.

Based  on our  due  diligence,  we  firmly  believe  that  competitors  in  each
respective segment both hold the Company's  subsidiaries in high regard and have
tremendous  strategic  interest.  Additionally,  a  publicly  traded  comparable
company  analysis as well as our due  diligence  supports  the notion that ample
demand  would  exist  for  Telephonics  Corporation  in the  public  market as a
stand-alone company.

Our analysis ultimately suggests that fair value for Griffon's stock approximates $31-$35, prior to certain adjustments as footnoted below. EST.
