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)	On April 26, 2004, the reporting person entered into a non-recourse loan (the "Loan") with a non-affiliated lender (the "Lender"). The Loan does not have a set maturity date. As partial collateral for the Loan, on December 9, 2008 the reporting person pledged to the Lender 21,660 shares of Common Stock. The reporting person has subsequently pledged to the Lender an additional 42,140 shares of Common Stock currently held as additional collateral for the Loan. The total collateral securing the Loan, based on current valuations, is valued at approximately 130% of the maximum amount the reporting person is permitted to borrow under the Loan. The pledged shares constitute approximately 39% of the total collateral securing the Loan.
(2)	The Loan and pledge provide that if an event of default on the Loan occurs, the Lender has the right to foreclose upon and sell the pledged shares to satisfy the unpaid balance of the amount owed; however, the reporting person will not generally be liable for any deficiency. Prior to the occurrence of an event of default, the reporting person retains voting power over the pledged shares and the right to receive dividends or distributions. This Form 4 was not timely filed as a result of the reporting person's inadvertent oversight of the reporting obligations associated with the pledged shares and the non-recourse nature of the Loan.

Note: File three copies of this Form, one of which must be manually signed. If space is insufficient, see Instruction 6 for procedure.

Potential persons who are to respond to the collection of information contained in this form are not required to respond unless the form displays a currently valid OMB number.
