                        EMPLOYMENT AGREEMENT
                        --------------------


           THIS  AGREEMENT,  made as of this 1st day of January,  1998 by and
between   EMCOR  GROUP,   INC.   (the   "Company")   and  FRANK  T.  MACINNIS
("Executive").


                              RECITALS
                              --------


           In order to induce  Executive to continue to serve as Chief Executive
Officer of the Company and as Chairman of the Board of  Directors of the Company
("the Board"),  the Company desires to provide  Executive with  compensation and
other benefits under the conditions set forth in this Agreement.

           Executive is willing to accept such  continuation  of employment  and
perform  services  for  the  Company  and its  subsidiaries,  on the  terms  and
conditions hereinafter set forth.

           It is therefore hereby agreed by and between the parties as follows:






           1.   Employment.

           1.1  Subject  to the  terms and  conditions  of this  Agreement,  the
Company agrees to continue to employ  Executive  during the Period of Employment
(as hereinafter  defined) as the Chief Executive Officer of the Company.  In his
capacity as Chief  Executive  Officer of the Company,  Executive  shall have the
customary powers,  responsibilities  and authorities of chief executive officers
of similar  corporations  of the size,  type and nature of the Company as it may
exist from time to time,  including,  but not  limited  to,  authority  over all
personnel  decisions  and  business  policies  and  practices,  subject  to  the
direction of the Board of Directors of the Company (the "Board").

           1.2  The  Company   shall,   during  the  Period  of  Employment  (as
hereinafter  defined,),  make  its best  efforts  to  ensure  the  retention  of
Executive as Chairman of the Board.

           1.3  Subject to the terms and  conditions  hereof,  Executive  hereby
agrees to  continue  employment  as Chief  Executive  Officer of the Company and
shall  devote his full  working  time and  efforts,  to the best of his ability,
experience  and  talent,  to  the  performance  of  the  services,   duties  and
responsibilities  in connection  therewith  and agrees to continue to serve,  if
elected, as Chairman of the Board of the Company.  Except upon the prior written
consent of the Board,  Executive  will not during the Period of  Employment  (as
hereinafter defined) (i) accept any other employment or (ii) engage, directly or
indirectly, in any other business activity (whether or not pursued for pecuniary
advantage),  whether  or not it may be  competitive  with,  or whether or not it
might  place  him in a  competing  position  to  that  of,  the  Company  or any
subsidiary thereof.  Nothing in this Agreement shall preclude the Executive from
(i) engaging,  consistent  with his duties and  responsibilities  hereunder,  in
charitable  community  affairs,  (ii) managing his personal  investments,  (iii)
continuing to serve on the boards of directors on which he presently  serves (to
the extent such service is not  precluded by federal or state law or by conflict
of  interest  by reason of his  position  with the  Company),  or (iv)  serving,
subject to approval of the Board,  as a member of boards of  directors  of other
companies,  provided, that such activities do not interfere with the performance
of Executive's duties hereunder.  Notwithstanding the foregoing, it is expressly
acknowledged that Executive's  existing  ownership interest in, and service as a
director and/or officer of, ComNet  Communications,  Inc. have been disclosed to
the Company and that the continuing ownership thereof and any reasonable actions
associated  therewith,  including without  limitation,  continuing as a director
and/or officer thereof, shall be permitted under the terms of this Agreement and
shall in no event constitute a breach hereof.

           2. Period of Employment.  Executive's period of employment  hereunder
shall commence on January 1, 1998 (the  "Commencement  Date") and shall continue
through the earlier of December  31, 2000 or the date of  termination  hereunder
(the "Period of Employment");  provided,  however, that the Period of Employment
shall  automatically  be extended for  successive  one-year  periods  unless the
Company  or  Executive,  at least six  months  prior to the end of such  period,
provides written notice to the other party of intent not to extend the Period of
Employment.

           3.   Compensation.

           3.1 Salary.  The  Company  shall pay  Executive a base salary  ("Base
Salary") at the rate of $700,000  per annum for the Period of  Employment.  Base
Salary shall be payable in accordance  with the ordinary  payroll  practices the
Company.  Executive's rate of Base Salary shall be increased on the first day of
each calendar year  occurring  during the Period of  Employment,  beginning with
January 1, 1999, by the  percentage  increase for the prior year in the consumer
price  index  for the area in which  the  principal  office  of the  Company  is
located,  as  determined  by the U.S.  Department  of  Commerce,  or the  amount
specified by the Board, whichever is greater.

           3.2  Bonus.  In  addition  to his  Base  Salary,  Executive  shall be
entitled, while he remains employed hereunder, in respect of each calendar year,
to an annual  bonus (the  "Bonus")  payable in cash and at such times as bonuses
are customarily paid to senior executives of the Company. For each calendar year
during the Period of Employment,  the  Compensation  Committee of the Board (the
"Committee") shall establish, after consultation with Executive, a formula which
shall determine the amount of Executive's Bonus for the calendar year;  provided
that Executive's target bonus shall be no less than $600,000 for each such year.

           3.3 Supplemental Benefit Credits.  Executive shall be fully vested in
all  employee  benefit  plans of the Company with respect to which the amount of
any benefits  payable  thereunder  is determined in whole or in part by years of
service with the Company.

           3.4 Stock  Options.  (a) During each  calendar  year in the Period of
Employment,  the Company shall  recommend to the  Compensation  Committee of the
Board that  Executive  shall  receive an option  ("Option") to purchase not less
than  25,000  shares of common  stock of the Company  ("Shares")  at fair market
value pursuant to the Company's  then  applicable  stock option plan.  Each such
Option shall be exercisable  with respect to the Shares  subject  thereto on the
first anniversary of the date of grant.

           (b) In  addition,  Executive  was granted on November  21,  1997,  an
Option to purchase 200,000 Shares at fair market value pursuant to the Company's
stock option plan. This Option shall have a ten-year term and shall vest in full
on November 21, 2006,  provided that with respect to successive groups of 50,000
Shares, the Option shall, if earlier, vest when the fair market value of a Share
first equals or exceeds $25, $30, $35 and $40, respectively.

           (c) In the  event of  Executive's  termination  of  employment  under
Section 6.1, each Option shall become immediately  exercisable in full and shall
remain exercisable for the balance of its ten-year term.

           4.   Employee Benefits.

           4.1 Employee  Benefit Plans and  Programs.  The Company shall provide
Executive  during the Period of  Employment  with  coverage  under any  employee
benefit  programs,  plans and practices  (commensurate  with his position in the
Company) in accordance with the terms thereof, which the Company currently makes
available generally to its senior executive officers, or which the Company, with
Board  approval,  elects to make  available  generally  to its senior  executive
officers hereafter,  including,  but not limited to (a) retirement,  pension and
profit-sharing; and (b) medical, dental, hospitalization,  life insurance, short
and long-term disability, accidental death and dismemberment and travel accident
coverage;  provided  that  Executive  shall  pay such  portion  of the  premiums
therefor as is customarily paid by senior executives of the Company.

           4.2 Vacation, Fringe and Other Benefits.  Executive shall be entitled
to the number of vacation days  customarily  accorded  senior  executives of the
Company.  In addition,  during the Period of  Employment,  the Company shall pay
Executive  $700 per month for leasing  (plus  maintenance  and  insurance) of an
automobile.  The Company shall also  reimburse  Executive for (a) all initiation
fees and monthly dues for membership in a club suitable for entertaining clients
of the Company and (b) all legal  expenses  incurred by Executive in  connection
with the negotiation and drafting of this Agreement.  The Company shall bear the
cost of any  increased tax  liability of Executive  caused by the  provisions of
this Section 4.2.

           5. Directors and Officers Liability. The Company shall keep in effect
during the Period of Employment,  a policy of directors' and officers' liability
insurance  for  officers and  directors of the Company to the extent  reasonably
available,  at such reasonable  levels of coverage as are agreed to by Executive
and the Board from time to time.

           6.   Termination of Employment.

           6.1 Termination Not For Cause or For Good Reason. (a) The Company may
terminate  Executive's  employment at any time,  and Executive may terminate his
employment at any time. If  Executive's  employment is terminated by the Company
other than for Cause (as  hereinafter  defined),  or  Executive  terminates  his
employment for Good Reason (as hereinafter defined), Executive shall be entitled
to receive a lump sum cash payment  (but not in  substitution  for  compensation
already earned) in an amount equal to the sum of:

            (i) the greater of (A) Executive's Base Salary at the highest annual
rate in effect during the Period of Employment,  for the period from the date of
termination  through December 31, 2000 or (B) two times  Executive's Base Salary
at its then current annual rate;

           (ii) the greater of (A) Executive's  target Bonus pursuant to Section
3.2 times the number full or partial  calendar years  remaining from the date of
termination through December 31, 2000 or (B) two times Executive's target Bonus.

           (iii) an amount equal to  Executive's  Bonus,  for any calendar  year
ending  before  such  termination  occurs,  which  would have been  payable  had
Executive  remained in employment until the date such Bonus would otherwise have
been paid;

           (iv)an amount equal to Executive's target Bonus for the calendar year
in which the  termination of employment  occurs,  multiplied by a fraction,  the
numerator of which is the number of days in such  calendar  year that  Executive
was an employee of the Company, and the denominator of which is 365; and

           (v)in the event of a  termination  of  Executive's  employment by the
Company other than for Cause or by Executive for Good Reason  following a Change
in Control,  the factor of two in clause (B) of  subsections  6.1(a)(i) and (ii)
shall be increased to three.

           (b) In  addition  to the  amount  described  in  subsections  6.1(a),
Executive shall be entitled to receive:

           (i) until the earlier of December 31, 2000 or 18 months from the date
of  termination,   Executive  (and,  to  the  extent   applicable,   Executive's
dependents) shall continue to be covered,  at the Company's  expense,  under the
Company's  medical,  dental and  hospitalization  coverage plans,  and until the
earlier of December 31, 2000 or 6 months from the date of termination, Executive
shall  continue to be covered,  at the  Company's  expense,  under the Company's
group life, short and long-term  disability,  accidental death and dismemberment
and travel  accident  coverage  plans  described  in  Section  4.1 hereof or the
Company will provide for equivalent coverage; and

           (ii) all  payments  to which  Executive  has vested  rights as of the
expiration  of the Period of  Employment  under  employee  benefit,  disability,
insurance  and similar  plans which  provide for  payments  beyond the Period of
Employment.

           (c) For purposes of this  Agreement,  "Good Reason" shall mean any of
the following (without Executive's express prior written consent):

            (i)  The   assignment   to   Executive  by  the  Company  of  duties
inconsistent with Executive's  positions,  duties,  responsibilities,  titles or
office as set forth in Section 1 hereof,  or any reduction by the Company of his
duties or  responsibilities  or any removal of  Executive  from the  position of
Chairman  and  Chief  Executive  Officer  or any  failure  to elect or  re-elect
Executive as Chairman of the Board, except in connection with the termination of
Executive's  employment (A) upon the  termination of the Period of Employment on
December 31, 2000, (B) upon the  termination of a succeeding  one-year Period of
Employment  (as provided for under  Section 2 hereof),  (C) for Cause,  (D) as a
result of Executive's  Permanent Disability (as hereinafter defined) or death or
(E) by Executive other than for Good Reason;

           (ii) A reduction by the Company in Executive's Base Salary, except as
provided herein, as in effect at the commencement of employment  hereunder or as
the same may be increased from time to time during the Period of Employment;

           (iii) The failure by the Company to obtain the specific assumption of
this Agreement by any successor or assign of the Company or any person acquiring
substantially all of the Company's assets;

           (iv)  Failure by the Company to perform in any  material  respect its
obligations  under  this  Agreement,  where  such  failure  shall  not have been
remedied  within 30 days after  Executive  shall have  notified  the  Company in
writing thereof;

            (v) Any material  reduction in Executive's  compensation or benefits
following  a Change in Control or  Executive's  principal  business  location is
changed to a location  more than 30 miles from  Executive's  principal  business
location (other than a relocation to New York, New York)  immediately prior to a
Change in Control; or

           (vi)  The  Company  shall  cease  to keep in  effect  the  policy  of
directors' and officers'  liability insurance for Executive described in Section
5;

           (d) If all or any portion of the payments or benefits  provided under
Section 6.1,  either alone or together  with other  payments and benefits  which
Executive  receives  or is then  entitled  to receive  from the  Company,  would
constitute a "parachute payment" within the meaning Section 28OG of the Internal
Revenue Code of 1986, as amended  ("Code"),  Executive shall be entitled to such
additional payments as may be necessary to ensure that the net after tax benefit
of all payments  under this Section 6.1,  including the payment  provided for in
this subsection  6.1(c) shall be equal to the net after tax benefit of Executive
as if no excise tax had been imposed under Section 4999 of the Code.

           The foregoing  calculations  shall be made, at the Company's expense,
by the Company and Executive.  If no agreement on the  calculations  is reached,
Executive and the Company shall agree to the selection of an accounting  firm to
make the calculations. If no agreement can be reached regarding the selection of
an accounting firm, the Company shall select a nationally  recognized accounting
firm which has no current or recent business  relationship with the Company. The
determination  of any such firm selected  shall be conclusive and binding on all
parties.

           (e) For purposes of this  Agreement,  a "Change of Control"  shall be
deemed to have occurred when:

           (i) any  person or  persons  acting  in  concert  (excluding  Company
      benefit plans)  becomes the beneficial  owner of securities of the Company
      having at least 25% of the voting power of the Company's then  outstanding
      securities (unless the event causing the 25% threshold to be crossed is an
      acquisition of voting common securities  directly from the Company,  other
      than  upon  the  conversion  of  convertible   debt  securities  or  other
      securities and/or the exercise of options or warrants); or

           (ii) the  shareholders  of the  Company  shall  approve any merger or
      other business combination of the Company,  sale or lease of the Company's
      assets or combination of the foregoing  transactions (the  "Transactions")
      other than a Transaction  immediately  following which the shareholders of
      the Company and any trustee or fiduciary of any Company  employee  benefit
      plan  immediately  prior to the Transaction own at least 65% of the voting
      power,  directly or  indirectly,  of (A) the surviving  corporation in any
      such merger or other business combination;  (B) the purchaser or lessee of
      the  Company's  assets;  or (C) both  the  surviving  corporation  and the
      purchaser or lessee in the event of any combination of Transactions; or

           (iii)  within any 24 month  period,  the persons  who were  directors
      immediately   before  the   beginning  of  such  period  (the   "Incumbent
      Directors") shall cease (for any reason other than death) to constitute at
      least a majority of the Board or the board of  directors of a successor to
      the Company.  For this purpose, any director who was not a director at the
      beginning of such period  shall be deemed to be an  Incumbent  Director if
      such director was elected to the Board by, or on the  recommendation of or
      with the  approval  of,  at least  two-thirds  of the  directors  who then
      qualified  as  Incumbent  Directors  (so  long  as such  director  was not
      nominated  by a person who has  expressed  an intent to effect a Change of
      Control or engage in a proxy or other control contest).

           (f) All cash  payments  under this  Section  6.1 shall be made by the
Company  within  30  calendar  days  following  the  event  giving  rise to such
payments.

           6.2  Permanent  Disability.   If  as  a  result  of  the  Executive's
incapacity  due to physical or mental  illness,  the  Executive  shall have been
absent from his duties with the Company on a full-time basis for six consecutive
months (a "Permanent  Disability") during his Period of Employment,  the Company
or Executive may terminate his employment on written notice thereof,  the Period
of Employment shall terminate on the giving of such notice, and the compensation
to which Executive is entitled pursuant to Section 3.1 shall be paid through the
last day of the month in which the notice is given. In addition, Executive shall
be entitled to receive:

           (a) all  unpaid  amounts,  as of the  date of  such  termination,  in
respect of any Bonus for any calendar  year ending  before the calendar  year in
which such  termination  occurs,  which would have been  payable  had  Executive
remained in employment until the date such Bonus would otherwise have been paid,
plus  Executive's  target  Bonus for the calendar  year in which his  employment
terminates,  multiplied  by a fraction,  the numerator of which is the number of
days in such calendar year the Executive was an employee of the Company, and the
denominator of which is 365;

           (b) until the earlier of December 31, 2000 or 24 months from the date
of  termination  for  Permanent  Disability,   Executive  (and,  to  the  extent
applicable, Executive's dependents) shall continue to be covered under Company's
medical,  dental,  hospitalization,  group life, short and long-term disability,
accidental death and  dismemberment and travel accident coverage plans described
in Section 4.1 or the Company will  provide for  equivalent  coverage;  provided
that if Executive is provided with comparable  coverage by a successor  employer
any such coverage by the Company shall cease; and

           (c) all amounts payable under the Company's disability plans.

           6.3  Death.  In  the  event  of  Executive's   death  while  employed
hereunder,  the Period of Employment shall thereupon automatically terminate and
the Executive's estate or designated beneficiaries shall receive (i) payments of
Base  Salary  for a period of three  months  after  the date of death;  (ii) all
unpaid amounts, as of the date of such termination,  in respect of any Bonus for
any  calendar  year ending  before the calendar  year in which such  termination
occurs, which would have been payable had Executive remained in employment until
the date such Bonus would  otherwise  have been paid,  plus  Executive's  target
Bonus for the calendar year in which his employment terminates,  multiplied by a
fraction, the numerator of which is the number of days in such calendar year the
Executive was an employee of the Company,  and the  denominator of which is 365;
and (iii) any death benefits  provided under the employee benefit  programs,  in
accordance with their terms.

           6.4 Voluntary Resignation;  Discharge for Cause. If Executive resigns
voluntarily,  other than for Good Reason or Permanent Disability, or the Company
terminates  the  employment  of Executive at any time for Cause,  the  Company's
obligations under this Agreement to make any further payments to Executive shall
thereupon,  to the extent  permitted  by law,  cease and  terminate  except with
respect to all unpaid amounts, as of the date of such termination, in respect of
any Bonus for any calendar year ending  before such  termination  occurs,  which
would have been payable had Executive remained in employment until the date such
bonus would  otherwise  have been paid.  In  addition,  Executive  shall  remain
entitled to all vested amounts and benefits under the Company's employee benefit
programs, plans and practices,  including,  without limitation, the supplemental
benefit credits provided for under Section 3.3 hereof. The term "Cause" shall be
limited to (a) action by Executive  involving willful  malfeasance in connection
with his employment which results in material harm to the Company,  (b) material
and continuing  breach by Executive of the terms of this Agreement  which breach
is not cured within 60 days after  Executive  receives  written  notice from the
Company  of any such  breach  or (c)  Executive  being  convicted  of a  felony.
Termination  of  Executive  for  Cause  pursuant  to this  Section  6.4 shall be
communicated by a Notice of Termination  given within six months after the Board
both (i) had knowledge of conduct or an event allegedly  constituting  Cause and
(ii) had  reason to believe  that such  conduct  or event  could be grounds  for
Cause.  For  purposes  of this  Agreement a "Notice of  Termination"  shall mean
delivery to Executive  of a copy of a resolution  duly adopted by the Board at a
meeting of the Board  called and held for that  purpose  (after not less than 10
days' notice to Executive  ("Preliminary Notice") and reasonable opportunity for
Executive,  together with the Executive's  counsel, to be heard before the Board
prior to such  vote),  finding  that in the good  faith  opinion  of the  Board,
Executive was guilty of conduct set forth in the third  sentence of this Section
6.4 and specifying the particulars  thereof in detail.  The Board shall no later
than  30  days  after  the  receipt  of  the  Preliminary  Notice  by  Executive
communicate  its  findings  to  Executive.  A  failure  by the Board to make its
finding of Cause or to  communicate  its  conclusions  within such 30-day period
shall be deemed to be a finding  that  Executive  was not guilty of the  conduct
described in the second sentence of this Section 6.4.

           6.5 Termination  Obligations.  (a) Executive hereby  acknowledges and
agrees that all personal property,  including,  without  limitation,  all books,
manuals,  records,  reports, notes, contracts,  lists, and other documents,  and
equipment  furnished to or prepared by Executive in the course of or incident to
his  employment,  belong to the Company  and shall be  promptly  returned to the
Company upon termination of the Period of Employment.

           (b) Upon termination of the Period of Employment, the Executive shall
be deemed to have resigned from all offices and directorships then held with the
Company or any subsidiary or affiliate thereof.

           7.  Confidential   Information.   During  and  after  the  Period  of
Employment,  Executive  shall not disclose to any person (other than an employee
or agent of the Company or any affiliate of the Company  entitled to receive the
same) any confidential  information  relating to the business of the Company and
obtained by him while providing services to the Company,  without the consent of
the Board, or until such information ceases to be confidential.

           8. Non-Competition. In the event Executive's employment is terminated
by the Company for Cause or Executive terminates his employment with the Company
without Good Reason,  Executive shall not, for a period ending on the earlier of
(i) 18 months  from the date of such  termination  or (ii)  December  31,  2000,
accept any other  employment  or engage,  directly or  indirectly,  in any other
business  activity  which  is  competitive  with  that  of  the  Company  or any
subsidiary thereof;  provided however,  that Executive's  ownership interest in,
and service as a director and/or officer of, ComNet  Communications,  Inc. shall
not be deemed to be competitive with the Company or any subsidary thereof.

           9. Expenses.  Executive is authorized to incur reasonable expenses in
carrying out his duties and  responsibilities  under this  Agreement,  including
expenses   for   travel  and   similar   items   related  to  such   duties  and
responsibilities.  The Company will  reimburse  Executive  for all such expenses
upon  presentation by Executive from time to time of an itemized account of such
expenditures.

           10.  No  Obligation  to  Mitigate  Damages.  Executive  shall  not be
required to mitigate  damages or the amount of any  payment  provided  for under
this Agreement by seeking (and no payment otherwise  required hereunder shall be
reduced on account of) other  employment  or  otherwise,  nor will any  payments
hereunder  be subject to offset in respect of any claims  which the  Company may
have against Executive.

           11.  Notices.  All notices or  communications  hereunder  shall be in
