Pursuant to the terms of a letter agreement among WRH, Purchaser, Parent and Park Avenue (the "Park Avenue Letter Agreement"), Park Avenue has agreed to tender into the Offer the Park Avenue Shares and to enter into a Tender Agreement with Parent and the Purchaser containing substantially the terms described above prior to any foreclosure on the Park Avenue Shares. - ------------------------------------------------------------------------------- Item 7.
