------------------------------                             ---------------------

The Schedule 13D filed on December 20, 2006 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 E. Hall and Conrad Bringsjord (collectively, the
"Reporting Persons"), with respect to the shares of Common Stock, par value
$0.25 per share (the "Shares"), of Griffon Corporation, a Delaware corporation
(the "Issuer"), as previously amended by Amendment No. 1 dated February 7, 2007
and Amendment No. 2 dated March 15, 2007, is hereby amended as set forth herein
by this Amendment No. 3.


ITEM 3.        SOURCE AND AMOUNT OF FUNDS OR OTHER CONSIDERATION.

Item 3 of the Schedule 13D is hereby amended and restated as follows:

     Funds for the purchase of the Shares reported herein were derived from
available capital of CMSF and CSO. A total of approximately $59.2 million was
paid to acquire such Shares.

ITEM 4.        PURPOSE OF TRANSACTION.

     Item 4 of the Schedule 13D is hereby amended by the addition of the
following:

     On May 9, 2007, CGI delivered a letter to the Issuer's board of directors
expressing disappointment over the extent of the Issuer's decline in earnings
and its inability to responsively adjust cost structures, particularly in light
of the performance of other industry participants during the same period. CGI
urged the Issuer's management to effect significant restructuring savings. GCI
noted the Issuer's belated retention of Goldman Sachs to explore strategic
alternatives, but urged that its mandate be narrowed to either a sale of the
Issuer's business in whole or in parts or a form of public recapitalization
aided by a qualified financial sponsor. In addition, CGI observed that the
Issuer's board of directors has yet to address any of the "management
entrenching" issues outlined in previous letters sent by CGI. CGI stated that it
would be compelled to seek a change through direct shareholder means in the
event that the Issuer failed to address CGI's concerns and maximize shareholder
value.  A copy of this letter is attached hereto as Exhibit D and is
incorporated herein by reference.

ITEM 5.        INTEREST IN SECURITIES OF THE ISSUER.

Paragraphs (a), (b) and (c) of Item 5 of the Schedule 13D are hereby amended and
restated as follows:

     (a) As of the close of business on May 8, 2007, the Reporting Persons
beneficially owned an aggregate of 2,476,811 Shares, constituting approximately
8.3% of the Shares outstanding.

     The aggregate percentage of Shares beneficially owned by the Reporting
Persons is based upon 29,845,689 Shares outstanding, which is the total number
of Shares outstanding as of January 31, 2007 as reported in the Issuer's
Quarterly Report on Form 10-Q for the period ended December 31, 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 2,193,331 Shares held by CMSF and the 283,480
Shares held by CSO. By virtue of his direct and indirect control of CGI, George
E. 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 E. Hall and Conrad Bringsjord are
deemed to have shared voting and shared dispositive power with respect to an
aggregate of 2,476,811 Shares.

     (c) Information concerning transactions in the Shares effected by the
Reporting Persons since the most recent filing on Schedule 13D 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.

Item 6.        CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH
               RESPECT TO SECURITIES OF THE ISSUER.

Item 6 of the Schedule 13D is hereby amended and restated as follows:

     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 162,000 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.
