Agreement.The undersigned will not, during the period of employment by or with the
Company, and for a period of twelve (12) months immediately following the
termination of employment, for any reason whatsoever, directly or indirectly,
on his or her own behalf or on behalf of or in conjunction with


any other person,
company, partnership, corporation or business of whatever nature:  a. engage, as an officer,
director, shareholder, owner, partner, joint venturer, or in a managerial
capacity, whether as an employee, independent contractor, consultant or
advisor, or as a sales representative, or make guarantee loans or invest, in or
for any business engaged in the business of mechanical contracting services,
including heating, ventilation and air conditioning, plumbing, fire protection,
piping and electrical and related services (Services) in competition with the
Company or any of its affiliates within seventy-five (75) miles of where
the Company or any affiliated operation or subsidiary conducts business if
within the preceding two (2) years the undersigned has had responsibility
for, or material input or participation in, the management or operation of such
other operation or subsidiary;  b. call upon any person who
is, at that time, an employee of the Company or any of its affiliates in a
technical, managerial or sales capacity for the purpose or with the intent of
enticing such employee away from or out of the employ of the Company or any
affiliate;  c. call upon any person or
entity which is at that time, or which has been within two (2) years prior

competitor, which acquisition candidate either was called upon the undersigned
on behalf of the Company or any affiliate or was the subject of an acquisition
analysis made by the undersigned on behalf of the Company or any affiliate for
the purpose of acquiring such acquisition candidate.  Notwithstanding the
above, the foregoing agreements and covenants shall not be deemed to prohibit
the undersigned from acquiring as an investment not more than one percent (1%)
of the capital stock of a competing business whose stock is traded on a
national securities exchange or on an over-the-counter or similar market. It is
specifically agreed that the period during which the agreements and covenants
of the undersigned made in this Section 13 shall be effective shall be
computed by excluding from such computation any time during which the
undersigned is in violation of any provision of this Section 13.  14. Remedies
in the Event of Breach. If the Company determines that the undersigned is not in
compliance with the agreements and covenants set forth in Section 13
above, and such non-compliance has not been authorized in advance in a specific
written waiver from the Company, the Committee may, without limiting other
remedies that may be available to the Company, cause all or any portion of the
Award to be forfeited, whether or not previously vested, and may require the
undersigned to remit or deliver to the Company the amount of any consideration
received by the undersigned upon the sale of any Shares delivered under the
Award. The undersigned acknowledges and agrees that the calculation of damages
from a breach of the foregoing agreements and covenants would be difficult to
calculate accurately and that the remedies provided for herein are reasonable
and not a penalty. The undersigned further agrees not to challenge the
reasonableness of this provision even if the Company rescinds or withholds the delivery
of Shares hereunder or withholds any amount otherwise payable to the
undersigned as an offset to effectuate the foregoing.   Very
  truly yours,
