Item 4.	Purpose of Transaction

	In March 2006, the LLC distributed 10,000 shares of Common Stock
	to an unrelated party pursuant to the Thomas P. Clark Trust dated
	November 9, 2004 (the "TC Trust").  The Trustee of the TC Trust is R Clark.

	On July 6, 2006, the LLC sold 140,000 shares of Common Stock for
	$10.25 per share to an unrelated party. Excluding this July 6, 2006
	sale, since the filing of Amendment 7 to Schedule 13D filed in July
	2005, the LLC has sold a total of 280,000 shares of Common Stock.

	Except as noted herein, the Reporting Persons have no present plans
	or proposals that relate to or would result in any transaction of the
	kind described in paragraphs (a) through (j) of Item 4.  In the future,
	however, the Reporting Persons reserve the right to adopt such plans
	or proposals, subject to applicable regulatory requirements, if any.

	Pursuant to an Amended and Restated Voting Agreement dated August 12, 1992,
	a copy of which was filed previously as Exhibit A to Amendment No. 1
	(the "1992 Voting Agreement") Thomas P Clark ("T Clark"), the former
	CEO of the Company and former original owner of the LLC's Common Stock,
	had agreed, along with other parties, to vote the shares of the Common
	Stock, owned or controlled by him, in favor of electing a representative
	designated by the Environmental Private Equity Fund II, L.P., a Delaware
	limited partnership ("EP Fund"), to the Company's Board of Directors.
	The Common Stock directly held by the LLC, which was transferred from
	T Clark as more fully described in the Schedule 13D/A filed with the
	Commission on May 13, 2005, will continue to be subject to the 1992
	Voting Agreement. EP Fund owns 341,880 shares of Common Stock of
	the Company or 2.3% of the total outstanding Common Stock.
	Companies affiliated with EP Fund who are parties to the 1992 Voting
	Agreement (the "EP Fund Entities") own an additional 1,221,288 shares
	of common stock or 8.2% of the total outstanding Common Stock.
	George W. Middlemas currently serves on the Board and was elected as the
	EP Fund representative.

	shares of Common Stock, or 10.9% of the outstanding Common Stock of
	the Company.

	The Trust, due to its majority ownership of the LLC, and R Clark as
	sole trustee of the Trust and as manager of the LLC, may be deemed to
	have indirect beneficial ownership of the 1,619,705 shares (10.9% of
	the total outstanding Common Stock) owned by the LLC.

	of Common Stock owned by, and disclaim the existence of a "group"
	within the meaning of Section 13(d)(3) of the Securities Exchange Act
	of 1934 with, the other parties to the 1992 Voting Agreement.

(b)	By reason of his role as manager, R Clark has the sole power to
	dispose of and vote 1,619,705 shares of Common Stock owned by the LLC,
	subject to the 1992 Voting Agreement.
