## Note O – Legal Proceedings 

In February 1995, as part of an investigation by the New York County District Attorney’s office into the business affairs of a general contractor that did business with EMCOR’s subsidiary, Forest Electric Corp. (“Forest”), a search warrant was executed at Forest’s executive offices. On July 12, 2000, Forest was served with a Subpoena Duces Tecum to produce certain documents as part of a broader investigation by the New York County District Attorney’s office into illegal business practices in the New York City construction industry. Forest has been informed by the New York County District Attorney’s office that it and certain of its officers are targets of the investigation. Forest intends to produce documents in response to the subpoena and to cooperate fully with the District Attorney’s office investigation as it proceeds. 

On July 31, 1998, a former employee of a subsidiary of EMCOR filed a class-action complaint on behalf of the participants in two employee benefit plans sponsored by EMCOR against EMCOR and other defendants for breach of fiduciary duty under the Employee Retirement Income Security Act. All of the claims relate to alleged acts or omissions which occurred during the period May 1991 to December 1994. The principal allegations of the complaint are that the defendants breached their fiduciary 

duties by causing the plans to purchase and hold stock of EMCOR when it was then known as JWP, Inc. and when the defendants knew or should have known it was imprudent to do so. The plaintiff has not made claim for a specific dollar amount of damages but generally seeks to recover for the benefit plans the loss in the value of JWP, Inc. stock held by the plans. EMCOR and the other defendants intend to vigorously defend the case. Insurance coverage may be applicable under an EMCOR pension trust liability insurance policy for EMCOR and those present and former employees of EMCOR who are defendants in the action. 

Substantial settlements or damage judgements against EMCOR arising out of these matters could have a material adverse effect on EMCOR’s business, operating results and financial condition. 

In addition to the above, EMCOR is involved in other legal proceedings and claims, asserted by and against EMCOR, which have arisen in the ordinary course of business. EMCOR believes it has a number of valid defenses to these actions and EMCOR intends to vigorously defend or assert these claims and does not believe that a significant liability will result. However, EMCOR cannot predict the outcome thereof or the impact that an adverse result of the matters discussed above will have upon EMCOR’s financial position or results of operations.
