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)	Does not include 7,843 shares held directly (including 1,083 shares acquired under the Company's Employee Stock Purchase Plan), 4,178 shares held indirectly by the Company's 401(k) plan, and 1,100 shares held indirectly by Mr. Engelhardt's spouse. This amendment corrects the number of shares held directly, which was inadvertantly understated by 30 shares in the originally-filed Form 4. The understatement was reflected in subsequently filed Form 4s.
(2)	The sale reported in this Form 4 was effected pursuant to a pre-existing Rule 10b5-1 trading plan adopted by the reporting person.
(3)	This amendment corrects the number of securities beneficially owned following the reported transaction, which was inadvertantly understated by 1,000 shares in the originally-filed Form 4. The understatement was reflected in subsequently filed Form 4s.

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.
