“Average Availability” means, (a) in the case of any calculation as of the last day of any fiscal quarter, the average daily Availability during the fiscal quarter then ended, or (b) in the case of any calculation as of the last day of any other fiscal month for purposes of Section 7.4(b), the average daily Availability during the three fiscal month period then ended, or (c) in the case of any calculation as of the last day of any other fiscal month for purposes of determining the Applicable Margin, the average daily Availability during the fiscal month then ended.

“Base Rate” means, for any day, a per annum rate equal to the greater of (a) the Prime Rate for such day; (b) the Federal Funds Rate for such day, plus 0.50%; or (c) the LIBOR Rate for a 30 day interest period as determined on such day, plus 1.0%. Each Interest Rate based upon the Base Rate shall be adjusted simultaneously with any change in the Base Rate.

(h) By deleting clause (q) of the definition of “Restricted Investment” contained in Annex A to the Credit Agreement, and by adding the word “and” immediately preceding clause (p) of such definition.

3. Amendments to Security Agreement. The Security Agreement is hereby amended by deleting the definitions of “Dominion Date” contained in Section 1 of the Security Agreement and by substituting in lieu thereof the following new definition:

“Dominion Date” means April 30, 2009, on which date Agent shall, in accordance with the terms of each Blocked Account Agreement, give notice to the applicable Clearing Bank that Agent is exercising dominion over the applicable Payment Account and that withdrawals by Grantors are no longer permitted from such Payment Account, provided that, Agent may exercise such dominion prior to April 30, 2009 if, at any time prior to such date, (a) the unpaid balance of Revolving Loans is greater than $0 or (b) an Event of Default occurs.
