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).
(2) Purchased through the Company's 401(k) plan from June 15, 2006, through December 4, 2006.
(1) On December 12, 2005, a voluntary reporting was made for the reporting person which incorrectly reported 30 shares granted to the reporting person for a 15 year service award. The correct number of shares awarded for the service award was 10; therefore, the amount of common stock beneficially owned has been adjusted accordingly. The overstatement of 20 shares also carried over into two subsequent Form 4 filings on December 21, 2005, and June 15, 2006. The filings with the incorrect number of shares are each being corrected by this Form 4 filing.

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.
