Selling Shareholders

         The Company acquired all of the issued and outstanding capital stock of
Parrott pursuant to the Purchase Agreement. In addition, SEI Sub acquired
certain real property owned by the Shareholders and utilized in connection with
the HVAC business of Parrott pursuant to the Real Property Agreement. In
connection with such transactions, the Company issued the Shares to the
Shareholders in a transaction exempt from the registration requirements of the
Securities Act. The Shares may be resold by a Shareholder through a registered
broker-dealer in accordance with the terms of the Prospectus.

Plan of Offering

         This Supplement relates to the reoffering, from time to time, of the
Shares through a registered broker-dealer. The Shareholders have designated
SunTrust Equitable Securities ("Equitable"), a registered broker-dealer, as
agent for the resale of the Shares. The Shares will be sold in private or block
transactions on the New York Stock Exchange or otherwise at fixed prices which
may be changed, at market prices prevailing at the time of the sale, at prices
related to such prevailing market price, or at negotiated prices. Equitable may
effect such transactions by selling the Shares to or through other
broker-dealers, and such broker-dealers may receive compensation in the form of
discounts, concessions or commissions from the Shareholders, Equitable and/or
the purchasers of the Shares for whom such broker-dealers may act as agent or to
whom they may sell as principal, or both (which compensation as to a particular
broker-dealer might be in excess of customary commissions). As a result of the
reoffering of the Shares pursuant to the Prospectus, as supplemented hereby, the
Company and Equitable may be deemed to be "underwriters" within the meaning of
Section 2(11) of the Securities Act, and any commissions received by (or
discounts allowed to) them and any profit on the resale of the Shares as
principal may be deemed to be underwriting discounts and commissions.
