Explanation of Responses:

*	If the form is filed by more than one reporting person, see Instruction 4(b)(v).
**	Intentional misstatements or omissions of facts constitute Federal Criminal Violations. See 18 U.S.C. 1001 and 15 U.S.C. 78ff(a).
(1)	In February 2002, Reporting Person had entered into a prepaid forward contract with DECS Trust IX (the Trust) pursuant to which he deposited 116,633 shares of LAB Common Stock into the Trust for an aggregate of $24.24 per share. Concurrently therewith, the Trust publicly issued DECS securities, each of which entitled the holder to receive LAB Common Stock or cash upon termination of the Trust between February 15 and May 15, 2005, depending on the public trading price of LAB common stock at that time. Because the price of LAB Common Stock was less than $31.580 per share on February 15, 2005, the date the Trust terminated, each holder of a DECS was enititled to receive one share of LAB common stock, or the cash equivalent, for each DECS owned. Reporting Person, therefore, was required to deliver 116,633 shares of LAB Common Stock, or the cash equivalent, on February 15, 2005. Prior to February 15, 2005, Reporting Person continued to beneficially own these shares of LAB Common Stock.
(2)	As a holder of 3,000 DECS securities, in accordance with the terms of the Trust, the Reporting Person received 3,000 shares of LAB Common Stock in exchange for his DECS Securities upon liquidiation of the Trust on February 15, 2005.
