On June 7, 2005,  EMCOR Group,  Inc.  filed a Form 8-K with the  Securities  and
Exchange Commission to report the following information:
     In its proxy  statement  dated April 27, 2005  ("Proxy  Statement"),  EMCOR
Group,  Inc.  ("EMCOR")  submitted to its stockholders a proposal to approve the
adoption by its Board of Directors of a 2005  Management  Stock  Incentive  Plan
(the "Plan")  that would  authorize  600,000  shares of EMCOR common stock to be
available for issuance as awards under the plan. The Plan would be  administered
by the Compensation and Personnel Committee of EMCOR's Board of Directors, which
has discretion to specify the amount, terms and conditions of awards.
     If  stockholders  approve  adoption of the Plan as  contained  in the Proxy
Statement,  the Compensation and Personnel has determined to administer the Plan
so that not more than 450,000 shares are awarded under the Plan.
     In Note I to its Consolidated  Financial  Statements  contained in its Form
10-K for the year ended December 31, 2004,  EMCOR provided  certain  information
concerning weighted average exercise prices and weighted average remaining lives
of options  outstanding  at December 31, 2004. As of April 20, 2005 the weighted
average remaining life of all options  outstanding  under  stockholder  approved
plans was 6.70 years,  and the  weighted  average  exercise  price and  weighted
average  remaining life of all options  outstanding  under plans not approved by
stockholders were $35.43 and 6.42 years, respectively.
