Press Release

NEW YORK, NEW YORK, March 18, 2011 - Griffon Corporation (NYSE: GFF) announced today that it has entered into a new five year cash flow revolving credit facility ("New Cash Flow Facility") pursuant to a previously disclosed commitment letter with JPMorgan Chase Bank N.A and J.P. Morgan Securities LLC. This facility refinances and replaces the existing revolving credit facilities at each of Telephonics Corporation and Clopay Ames True Temper Holding Corp.

The execution of the New Cash Flow Facility, along with the completion of $550 million 7.125% unsecured senior notes, completes the refinancing of substantially all of Griffon's domestic subsidiary debt with new debt at the parent company level.

The New Cash Flow Facility provides for revolving borrowings in an aggregate principal amount of up to $200,000,000 that will support Griffon's working capital requirements and its anticipated growth strategies. The facility also has a $50,000,000 accordion feature, exercisable if new or existing lenders agree to provide or increase their commitments.  The Borrower may elect to pay interest based on either a LIBOR or base benchmark rate, with no floor, plus an applicable margin that depends on Griffon's leverage ratio.  Initial pricing is LIBOR plus 2.75% or base rate plus 1.75%.  The facility is guaranteed by Griffon's material domestic subsidiaries, and is collateralized by substantially all the assets of Griffon and its material domestic subsidiaries.  The New Cash Flow Facility removes the lines of business restriction in the existing revolving credit facilities, resulting in increased flexibility for Griffon.

Commenting on the New Cash Flow Facility, Ron Kramer, Chief Executive Officer of the Company, said "The closing of our new revolving credit facility, together with yesterday's completion of our $550 million 7.125% unsecured senior notes offering, completes the successful refinancing of our balance sheet.  This puts us in an extraordinary position to continue to grow our Company."

Syndication for the New Cash Flow Facility was lead by J.P. Morgan Securities LLC.
