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) The sale of shares reported in this Form 4 were effected pursuant to a stock trading plan intended to comply with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, which was entered into effective August 29, 2006. The adoption of this plan was previously disclosed by the Company in its Current Report on Form 8-K filed with the Securities and Exchange Commission on September 6, 2006.
(2) All of the 463,300 shares of the Company?s common stock eligible for sale by Mr. Tucci pursuant to the stock trading plan that is intended to comply with Rule 10b5-1 of the Securities Exchange Act of 1934, as amended, as previously disclosed by the Company in its Current Report on Form 8-K filed with the Securities and Exchange Commission on September 6, 2006 have been sold. Thus, as reflected in Mr. Tucci?s end of period holdings in this Form 4, he no longer holds any shares of the Company?s common stock indirectly via the limited partnership described in the above referenced Form 8-K. The amount of shares of the Company?s common stock held indirectly via this limited partnership by Mr. Tucci was inadvertently understated due to a transposition of two numbers in certain of his prior Form 4 filings and has been adjusted in accounting for the transactions reported in this Form 4.

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.
