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)	Represents quarterly dividends on Lime Energy Co Series E Convertible Preferred Stock paid in additional shares of Series E Convertible Preferred Stock. Each share of Series E Convertible Preferred Stock is convertible into 100 shares of common stock.
(2)	Converstion rights do not expire.
(3)	Purchased pursuant to a private sale of common stock by the Company at $1.00 per share.
(4)	On June 29, 2006, Mr. Valentine converted 1,457 shares of Series E Convertible Preferred Stock into 145,700 shares of common. Prior to the issuance of common stock by the Company as part of a transaction that closed on June 29, 2006, the conversion rate of the Series E Convertible Preferred Stock was 6.67 shares of common stock per share of Series E Convertible Preferred Stock. However, the Series E Convertible Preferred Stock contained anti-dilution provisions which required the automatic adjustment to the conversion rate if the Company issued stock or securities convertible into common stock at a price below the Series E Preferred conversion price then in effect to the price of the new issuance. Because the Company issued common stock in a transaction which closed on June 29, 2006 at $1.00 per share, the Series E Preferred conversion rate was automatically adjusted to 100 shares of common stock per share of Series E Preferred converted.
