                 GRIFFON CORPORATION ANNOUNCES OPERATING RESULTS
                 -----------------------------------------------

                     FOR THE SECOND QUARTER OF FISCAL 2006
                     -------------------------------------


     Jericho,  New  York,  May 3, 2006 - Griffon  Corporation  (NYSE:GFF)  today
reported  operating results for the second quarter of fiscal 2006. Net sales for
the quarter ended March 31, 2006 increased to $366,151,000 up from  $322,473,000
for  the  second  quarter  of  fiscal  2005.  Income  before  income  taxes  was
$11,468,000  compared to $6,101,000  last year. Net income was $7,208,000 in the
current quarter compared to $4,144,000 last year. Diluted earnings per share for
the quarter was $.23 compared to $.13 in last year's second quarter.

     The improved  operating  results for the specialty plastic films segment in
the second  quarter of fiscal 2006  reflected  lower resin costs and a return to
normalized sales volume from its largest customer. Improved operating results in
our  garage  doors  segment  reflected  stabilized  steel  costs,  sales  volume
increases and a more  favorable  product mix.  Higher sales in the  installation
services  segment  reflected volume growth in the Phoenix and Las Vegas markets.
The electronic  information  and  communication  systems  segment,  Telephonics,
reflected higher sales and profits  principally due to the previously  announced
subcontract  award  from  Syracuse  Research  Corporation.  Telephonics  has now
received  subcontracts  in excess of  $175,000,000.  Approximately  70% of these
awards are expected to be completed by September 30, 2006 and the fulfillment of
the total award will be complete by the second quarter of fiscal 2007.


Net sales for the six months ended March 31, 2006 were $724,675,000 compared to $662,647,000 for the first six months of fiscal 2005. Income before income taxes for the six months was $22,261,000 compared to $23,656,000 last year. Net income was $13,984,000 compared to $13,336,000 for the first half of 2005. Diluted earnings per share for the six months was $.45 compared to $.43 last year. Cash flow from operations was $3,800,000 for the quarter, which together with existing cash, funded capital expenditures of $8,800,000. Also, during the quarter $5,300,000 was used to acquire approximately 225,000 shares of the company's common stock under its buyback program. Additional purchases will be made from time to time, depending on market conditions, at prices deemed appropriate by management or under a Rule 10b5-1 trading plan.
