EXHIBIT 10(l-3)

FIRST AMENDMENT TO THE CONTINUITY AGREEMENT
BETWEEN EMCOR GROUP, INC. AND MAXINE L. MAURICIO

This First Amendment (this “First Amendment”) dated this 10th day of April, 2017
is made by and between EMCOR Group, Inc. (the “Company”) and Maxine L. Mauricio
(the “Executive”).

WHEREAS, the Company and the Executive entered into a Continuity Agreement (the
“Continuity Agreement”) dated October 26, 2016; and

WHEREAS, the Company and the Executive desire and agree to amend the Continuity
Agreement, in accordance with Section 12 thereof, to remove from the calculation
of the Executive’s cash severance benefits the value of any perquisites provided
to the Executive in the year preceding a change of control.

NOW THEREFORE, in consideration of the mutual promises and agreements of the
parties as set forth below, the parties agree to this First Amendment, as
follows:

1.
Section 4(a) of the Continuity Agreement is hereby amended to read, in its
entirety, as follows:

“(a) Severance. As soon as practicable after the Termination, but in any event
no later than 10 business days following such Termination, the Company shall pay
or cause to be paid to Executive, a lump sum cash amount equal to three (3)
times the sum of (i) Executive’s annual base salary on the Effective Date (the
“Base Salary”), and (ii) the Bonus. In addition, at the time of the above
payment, Executive shall be entitled to an additional lump sum cash payment
equal to the sum of (A) Executive’s annual salary through the date of
termination, (B) an amount equal to Executive’s annual aggregate bonuses, for
any calendar year ending before such termination occurs, which would have been
payable had Executive remained employed until the date such bonus would
otherwise have been paid, (C) a pro rata portion of the Bonus (calculated
through the date of termination); and (D) an amount, if any, equal to
compensation previously deferred (excluding any qualified plan deferral) and any
accrued vacation pay, in each case, in full satisfaction of Executive’s rights
thereto. If payment of the amounts referred to herein is not made by the Company
to Executive within such 10 day period, the Company shall pay Executive interest
thereon at the rate of 10% per annum.”

Except as amended hereby, the Continuity Agreement shall remain in full force
and effect in accordance with its terms.

This First Amendment may be executed in two or more counterparts, each of which
shall be an original and all of which shall be deemed to constitute one and the
same instrument.
