EMCOR Group, Inc. and Subsidiaries

Notes to Condensed Consolidated Financial Statements (Unaudited)

NOTE A  Basis of Presentation

The accompanying  condensed consolidated financial statements have been prepared
by EMCOR Group, Inc. and Subsidiaries ("EMCOR"),  without audit, pursuant to the
interim  period  reporting  requirements  of Form  10-Q.  Consequently,  certain
information  and note  disclosures  normally  included in  financial  statements
prepared in conformity  with  accounting  principles  generally  accepted in the
United  States have been  condensed  or omitted.  Readers of this report  should
refer to the consolidated financial statements and the notes thereto included in
EMCOR's latest Annual Report on Form 10-K filed with the Securities and Exchange
Commission.

In the  opinion of EMCOR,  the  accompanying  unaudited  condensed  consolidated
financial  statements  contain  all  adjustments  (consisting  only of a  normal
recurring  nature)  necessary to present fairly the financial  position of EMCOR
and the results of its  operations.  The results of operations for the three and
six month  periods  ended June 30, 2003 are not  necessarily  indicative  of the
results to be expected for the year ending December 31, 2003.

On March 1, 2002,  EMCOR acquired from Comfort Systems USA, Inc. ("CSU") a group
of companies (the "Acquired  Comfort  Companies").  On December 19, 2002,  EMCOR
acquired  all the  capital  stock of  Consolidated  Engineering  Services,  Inc.
("CES") from  Archstone-Smith  Operating  Trust and others.  EMCOR  acquired two
additional  companies during 2002. These  acquisitions were accounted for by the
purchase  method,  and the  purchase  prices have been  allocated  to the assets
acquired and liabilities assumed,  based upon the estimated fair values of these
assets and liabilities at their  respective  dates of acquisition.  The purchase
price for CES is subject to adjustment  based on the difference  between the net
assets  of CES on the  closing  date and an agreed  upon  preclosing  date.  The
purchase price allocation is also subject to finalization.

Certain  reclassifications  of prior year  amounts  have been made to conform to
current year presentation.

NOTE B  New Accounting Pronouncements

In November 2002, the Financial  Accounting  Standards Board (the "FASB") issued
Financial   Accounting  Standards  Board  Interpretation  No.  45,  "Guarantor's
Accounting  and  Disclosure  Requirements  for  Guarantees,  Including  Indirect
Guarantees of Indebtedness of Others,  an  Interpretation of FASB Statements No.
5, 57, and 107 and  Rescission of FASB  Interpretation  No. 34" ("FIN 45" or the
"Interpretation").  FIN 45  clarifies  the  requirements  of FASB  Statement  of
Financial Accounting  Standards No. 5, "Accounting for Contingencies,"  relating
to the  guarantor's  accounting  for, and disclosure of, the issuance of certain
types of guarantees.  FIN 45 may require, that upon issuance of a guarantee, the
guarantor  to  recognize a  liability  for the fair value of the  obligation  it
assumes under that guarantee.  The disclosure  provisions of the  Interpretation
are  effective for  financial  statements of interim or annual  periods that end
after December 15, 2002. The Interpretation's provisions for initial recognition
and measurement should be applied on a prospective basis to guarantees issued or
modified  after  December  31,  2002,  irrespective  of the  guarantor's  fiscal
year-end.  The guarantor's  previous  accounting for guarantees that were issued
before the date of FIN 45's initial  application  may not be revised or restated
to reflect  the effect of the  recognition  and  measurement  provisions  of the
Interpretation.  EMCOR  has  determined  that the  adoption  of FIN 45 will only
impact  disclosures and that its accounting for guarantees is not impacted as of
June 30, 2003.

In January 2003, the FASB issued Statement of Financial Accounting Standards No.
148,  "Accounting  for  Stock-Based  Compensation - Transition  and  Disclosure"
("SFAS 148"). SFAS 148 amends FASB Statement of Financial  Accounting  Standards
No. 123,  "Accounting  for  Stock-Based  Compensation"  ("SFAS  123") to provide
alternative methods of transition for a voluntary change to the fair value based
method of accounting for stock-based employee  compensation.  In addition,  SFAS
148 amends the disclosure requirements of SFAS 123



NOTE B  New Accounting Pronouncements - (Continued)

to require prominent disclosures in both annual and interim financial statements
of the method of accounting for stock-based employee compensation and the effect
of the method used on reported  results.  SFAS 148 is effective for fiscal years
beginning  after  December  15,  2002 and was  adopted by EMCOR for all  periods
presented  herein.  EMCOR  did not  change  to the fair  value  based  method of
accounting for stock-based employee  compensation;  therefore,  adoption of SFAS
148 will only impact disclosures, not the financial results, of EMCOR.

In January  2003,  the FASB  issued  Interpretation  No. 46,  "Consolidation  of
Variable  Interest  Entities"  ("FIN 46").  FIN 46 expands upon and  strengthens
existing accounting guidance that addresses when a company should include in its
financial statements the assets, liabilities and activities of another entity. A
variable  interest  entity is a corporation,  partnership,  trust,  or any other
legal structure used for business  purposes that either (a) does not have equity
investors  with voting  rights or (b) has equity  investors  that do not provide
sufficient financial resources for the entity to support its activities.  FIN 46
requires  a variable  interest  entity to be  consolidated  by a company if that
company is subject to a majority of the risk of loss from the variable  interest
entity's  activities  or is  entitled  to  receive a  majority  of the  entity's
residual  returns or both.  FIN 46 is effective  for all new  variable  interest
entities  created or acquired  after  January 31, 2003.  For  variable  interest
entities created or acquired prior to February 1, 2003, the provisions of FIN 46
must be applied for the first interim or annual period  beginning after June 15,
2003. EMCOR is currently evaluating the effect that adoption of Fin 46 will have
on EMCOR's consolidated financial condition or results of operations.

In April 2003, the FASB issued Statement of Financial  Accounting  Standards No.
149,  "Amendment  of  Statement  133  on  Derivative   Instruments  and  Hedging
Activities"  ("SFAS  149").  SFAS  149  amends  and  clarifies   accounting  for
derivative  instruments,  including certain derivative  instruments  embedded in
other  contracts,  and for hedging  activities  under SFAS 133. The new guidance
amends  SFAS  133  for  decisions   made:   (a)  as  part  of  the   Derivatives
Implementation  Group process that effectively  required amendments to SFAS 133,
(b) in connection with other Board projects dealing with financial  instruments,
and (c) regarding implementation issues raised in relation to the application of
the  definition of a derivative.  The  amendments  set forth in SFAS 149 improve
financial reporting by requiring that contracts with comparable  characteristics
be accounted  for  similarly.  SFAS 149 is  generally  effective  for  contracts
entered  into or  modified  after June 30,  2003 and for  hedging  relationships
designated  after June 30, 2003. It is not expected that the  provisions of SFAS
149 will have a material  impact on  EMCOR's  consolidated  financial  position,
results of operations or cash flows.

In May 2003,  the FASB issued  Statement of Financial  Accounting  Standards No.
150, "Accounting for Certain Financial  Instruments with Characteristics of Both
Liabilities  and Equity"  ("SFAS  150").  SFAS 150  requires  certain  financial
instruments that embody  obligations of the issuer and have  characteristics  of
both  liabilities and equity to be classified as liabilities.  The provisions of
SFAS 150 are effective for financial  instruments entered into or modified after
May 31, 2003 and to all other  instruments that exist as of the beginning of the
first interim  financial  reporting  period beginning after June 15, 2003. EMCOR
does not have any financial  instruments  that meet the  provisions of SFAS 150;
therefore,  adopting  the  provisions  of  SFAS  150 is not  expected  to have a
material  impact  on  EMCOR's  consolidated   financial  position,   results  of
operations or cash flows.

There were options to purchase 219,403 shares of common stock outstanding during
both the three and six month  periods  ended June 30, 2003,  which  options were
anti-dilutive  and required to be excluded from the  calculation of diluted EPS.
There were no anti-dilutive stock options that were required to be excluded from
the  calculation  of diluted EPS for the three and six month  periods ended June
30, 2002.





NOTE D   Valuation of Stock Option Grants

At June 30, 2003, EMCOR had eight stock-based  compensation  plans and programs.
EMCOR applies Accounting  Principles Board Opinion No. 25, "Accounting for Stock
Issued to Employees"  ("APB 25") and related  interpretations  in accounting for
its stock options.  Accordingly, no compensation cost has been recognized in the
accompanying Condensed  Consolidated  Statements of Operations for the three and
six month  periods  ended June 30,  2003 and 2002 in  respect  of stock  options
granted  during those  periods  inasmuch as EMCOR  grants stock  options at fair
market value. Had compensation cost for these options been determined consistent
with SFAS 123 and SFAS 148, EMCOR's net income, basic earnings per share ("Basic
EPS") and diluted  earnings  per share  ("Diluted  EPS") would have been reduced
from the "as reported  amounts"  below to the "pro forma  amounts" below for the
three and six months  ended  June 30,  2003 and 2002 (in  thousands,  except per
share amounts):

NOTE F   Segment Information

EMCOR has the following  reportable  segments which provide services  associated
with the design, integration,  installation,  startup, operation and maintenance
of  various  systems:  United  States  electrical  construction  and  facilities
services (systems for generation and distribution of electrical power;  lighting
systems;  low voltage systems such as fire alarm,  security,  communications and
process control systems;  and voice and data systems),  United States mechanical
construction  and facilities  services  (systems for heating,  ventilation,  air
conditioning,  refrigeration  and clean room process  ventilation  systems;  and
plumbing,  process and high-purity  piping  systems),  United States  facilities
services,   Canada   construction  and  facilities   services,   United  Kingdom
construction and facilities services,  and Other international  construction and
facilities services. The segment "United States facilities services" principally
consists of those  operations  which  primarily  provide a portfolio of services
needed to support the operation and maintenance of customers' facilities (mobile
operation  and  maintenance  services,   site-based  operation  and  maintenance
services,  call center  services,  facility  planning and  consulting and energy
management  programs)  which services are not related to customer'  construction
programs.  The Canada,  United Kingdom and Other international  segments perform
electrical construction, mechanical construction and facilities services. "Other
international   construction  and  facilities   services"   represents   EMCOR's
operations  outside  of the  United  States,  Canada,  and  the  United  Kingdom
(primarily in South Africa and the Middle East during the periods presented).



The following tables present  information about industry segments and geographic
areas. The tables also present pro forma revenues and operating income as if the
2002  acquisitions  had  occurred  at the  beginning  of  fiscal  2002.  Certain
reclassifications  of prior  year  amounts  have been made to conform to current
year segment presentation. The unaudited pro forma revenues and operating income
are not necessarily indicative of future operating results (in thousands):

purchase  method,  and the  purchase  prices have been  allocated  to the assets
acquired and liabilities assumed,  based upon the estimated fair values of these
assets and liabilities at their  respective  dates of acquisition.  The purchase
price for CES is subject to adjustment  based on the difference  between the net
assets  of CES on the  closing  date and an agreed  upon  preclosing  date.  The
purchase price allocation is also subject to finalization.

Operating Segments

EMCOR has the following  reportable  segments which provide services  associated
with the design, integration,  installation,  startup, operation and maintenance
of  various  systems:  United  States  electrical  construction  and  facilities
services (systems for generation and distribution of electrical power;  lighting
systems;  low voltage systems such as fire alarm,  security,  communications and
process control systems;  and voice and data systems),  United States mechanical
construction  and facilities  services  (systems for heating,  ventilation,  air
conditioning,  refrigeration  and clean room process  ventilation  systems;  and
plumbing,  process and high-purity  piping  systems),  United States  facilities
services,   Canada   construction  and  facilities   services,   United  Kingdom
construction and facilities services,  and Other international  construction and
facilities services. The segment "United States facilities services" principally
consists of those  operations  which  primarily  provide a portfolio of services
needed to support the operation and maintenance of customers' facilities (mobile
operation  and  maintenance  services,   site-based  operation  and  maintenance
services,  call center  services,  facility  planning and  consulting and energy
management  programs) which services are not related to customers'  construction
programs.  The Canada,  United Kingdom and Other international  segments perform
electrical construction, mechanical construction and facilities services. "Other
international   construction  and  facilities   services"   represents   EMCOR's
operations  outside  of the  United  States,  Canada,  and  the  United  Kingdom
(primarily in South Africa and the Middle East during the periods presented).

EMCOR's  revenues  increased  $158.0 million for the three months ended June 30,
2003  compared  to the  second  quarter of 2002,  of which  $114.4  million  was
attributable to companies  acquired in 2002 and the balance was  attributable to
EMCOR's other subsidiaries. Revenues increased $408.7 million for the six months
ended June 30, 2003  compared to the six months  ended June 30,  2002,  of which
$315.0 million was attributable to companies acquired in 2002 and the balance to
EMCOR's  other  subsidiaries.  Excluding  the impact of 2002  acquisitions,  the
increase in revenues of $43.6  million for the three month period ended June 30,
2003  compared  to the same period in the prior year was  principally  due to an
increase  in the number of  longer-term  public  transportation  infrastructure,
power  generation  and healthcare  construction  projects and an increase in the
number of site-based  facilities  services operation and maintenance  contracts,
partially offset by a reduction in new construction  projects and  discretionary
spending,  typically  associated  with projects of less than six months duration
related  to  improvements,  enhancements  and  repairs  of  facilities,  in  the
commercial  office and industrial  markets.  In addition to these  factors,  the
revenues  increase  of $93.7  million  for the six months  ended  June 30,  2003
compared to the same period in the prior year was partially offset by a decrease
in private sector fast-track and development projects.

Revenues  of United  States  electrical  construction  and  facilities  services
business  units for the three  months  ended June 30, 2003 were  $322.0  million
compared to $289.3 million for the three months ended June 30, 2002. Revenues of
this segment for the six months ended June 30, 2003 were $575.9 million compared
to $577.0 million in the same period a year earlier.  The revenues for the three
and six month periods ended June 30, 2003,  when compared to the same periods in
2002,  reflected  an  increase in revenues  from  transportation  infrastructure
programs, power generation and healthcare projects, offset by a reduction in new
construction  projects and  discretionary  spending in the commercial office and
industrial markets attributable to the economic slow-down.  The six month period
ended June 30, 2003 also reflected the absence of fast-track projects.

Revenues  of United  States  mechanical  construction  and  facilities  services
business  units for the three  months  ended June 30, 2003 were  $426.1  million
compared to $437.9 million for the three months ended June 30, 2002. Revenues of
this segment for the six months ended June 30, 2003 were $842.6 million compared
to $745.0 million in the same period in the prior year. The decrease in revenues
for the three  months  ended June 30,  2003  compared  to the same period in the
prior year was due to a reduction in  discretionary  spending in the  commercial
office  and  industrial  markets  due to the  economic  slow-down,  as well as a
reduction  in demand for  services  as a result of cooler  than  normal  weather
conditions in the United  States.  The increase in revenues of $97.5 million for
the six month  period was  primarily  attributable  to revenues  from  companies
acquired in 2002.

United States  facilities  services revenues for the three months ended June 30,
2003 were $164.8 million  compared to $52.8 million for the same three months in
2002.  Revenues  for the six months  ended  June 30,  2003 were  $333.2  million
compared to $104.6 million in the same period in 2002. The revenues increases of
$112.0  million  and  $228.6  million  for  the  three  and six  month  periods,
respectively,  were  primarily  attributable  to revenues of $103.5  million and
$212.3 million, respectively, from companies acquired in 2002 and the balance to
increases in site-based  facilities operation and maintenance services performed
by EMCOR's  other  subsidiaries,  partially  offset by a reduction in demand for
mobile services  related to cooler than normal weather  conditions in the United
States and in discretionary spending due to the economic slow-down.

Revenues of Canada  construction  and  facilities  services for the three months
ended June 30, 2003 were $91.3  million  compared to $84.1 million for the three
months ended June 30, 2002. Revenues for the six months ended June 30, 2003 were
$184.3 million  compared to $138.7 million in the same period in the prior year.
The increase in revenues for both the three and six month  periods was primarily
attributable to continuing  work on longer-term  power  generation  construction
projects.

Revenues of United Kingdom  construction and facilities  services business units
for the three months ended June 30, 2003 were $140.2 million  compared to $122.3
million for the three months  ended June 30,  2002.  Revenues for the six months
ended June 30, 2003 were $269.4  million  compared to $231.4 million in the same
period in the prior year.  The  increase in revenues  for both the three and six
month periods was principally  attributable to the start-up of recently  awarded
contracts  in  the  facilities   services  and   transportation   infrastructure
construction markets.

Other  international  construction and facilities services activities consist of
EMCOR's  operations  primarily in the Middle East and South  Africa.  All of the
current projects in these markets are being performed by joint ventures in which
EMCOR has less than majority ownership.  Accordingly, the results of these joint
venture operations are accounted for under the equity method of accounting,  and
revenues  attributable  to such joint  ventures are not reflected as revenues in
the consolidated financial statements. EMCOR continues to selectively pursue new
business in these markets and Continental Europe;  however,  the availability of
opportunities  has been  significantly  reduced  as a result  of local  economic
factors.

                                             For the six months ended June 30,

Gross profit                                      $  240,044       $  209,602
Gross profit, as a percentage of revenues              10.9%            11.7%

Gross profit  (revenues less cost of sales) increased $3.1 million for the three
months ended June 30, 2003 to $123.3  million  compared to $120.2  million gross
profit for the three months ended June 30,  2002.  As a percentage  of revenues,
gross  profit  decreased to 10.8% from 12.2% for the three months ended June 30,
2003 and 2002, respectively. Gross profit for the six months ended June 30, 2003
of $240.0  million was $30.4 million  higher than the $209.6 gross profit in the
same period last year.  As a percentage of revenues,  gross profit  decreased to
10.9% from 11.7% for the six months ended June 30, 2003 and 2002,  respectively.
The increase in gross profit in both the three and six month 2003  periods,  was
primarily due to gross profit of $22.4 million and $54.2 million,  respectively,
from  companies  acquired  in 2002.  This  increase  was  partially  offset by a
decrease  in gross  profit  for the three and six  months  ended  June 30,  2003
compared to the same periods in the prior year primarily  attributable to losses
from construction activity in the United Kingdom and a reduction in gross profit
from certain mechanical construction operations. The decrease in gross profit as
a  percentage  of  revenues  was  attributable  to a  change  in the mix of work
performed with a higher  percentage of longer-term  (over one year duration) new
construction  projects  in  the  institutional,  healthcare  and  transportation
sectors and a lower  percentage of work in the commercial  sector,  particularly
fast-track  (less than six months) office  construction and renovation work. New
construction  projects are typically  characterized  by lower gross profits than
fast-track  commercial  work.  In  addition,  gross  profit  declines  were also
attributable to a decrease in discretionary  spending and competitive  pressures
due to the economic  slow-down.  These  decreases  were  partially  offset by an
increase in  facilities  services  work which is  generally  performed  at gross
margins higher than construction  work. The revenue for such work increased over
the prior year due to 2002 acquisitions.

Selling, general and administrative expenses for the three months ended June 30,
2003 increased $13.3 million to $106.6 million compared to $93.3 million for the
three months ended June 30, 2002. Selling,  general and administrative  expenses
as a percentage  of revenues were 9.3% for the three months ended June 30, 2003,
compared to 9.5% for the three months ended June 30, 2002. Selling,  general and
administrative  expenses  for the six  months  ended June 30,  2003 were  $215.8
million,  an increase of $45.7  million  compared to $170.1  million for the six
months ended June 30, 2002.  Selling,  general and administrative  expenses as a
percentage  of  revenues  were  9.8% for the six  months  ended  June 30,  2003,
compared to 9.5% for the six months  ended June 30,  2002.  Included in selling,
general and  administrative  expenses was  amortization  expense of identifiable
intangible  assets associated with acquisitions of $0.9 million and $1.8 million
for the three and six month periods ended June 30, 2003, respectively. Excluding
2002 acquisitions, selling, general and administrative expenses (including costs
of acquisitions integration) were approximately $89.2 million (8.6% of revenues)
and $166.8  million (8.8% of revenues) for the three and six month periods ended
June 30, 2003,  respectively,  compared to $93.3  million (9.5% of revenues) and
$170.1 million (9.5% of revenues) for the same three and six month periods ended
June 30, 2002.  The decrease in selling,  general and  administrative  expenses,
excluding the 2002 acquired  companies,  was attributable to a managed reduction
of both variable and fixed  expenses  across EMCOR as a result of changes in its
business activities.

EMCOR had operating  income of $16.6 million for the three months ended June 30,
2003 compared with operating  income of $26.9 million for the three months ended
June 30, 2002.  Operating income was $24.2 million and $39.5 million for the six
months ended June 30, 2003 and 2002, respectively. The decrease of $10.3 million
and $15.2 million in operating  income for the three and six month periods ended
June 30,  2003 as  compared  to the same  periods in 2002 was due  primarily  to
operating  losses in the United  Kingdom,  as well as a reduction  in  operating
income from certain United States mechanical construction  operations,  due to a
reduction in discretionary  spending related to the economic slow-down, a change
in the  type  of  work  performed  to  longer-term  construction  projects  that
generally has produced lower gross profits than fast-track commercial work and a
reduction  in demand for  services  as a result of cooler  than  normal  weather
conditions in the United  States.  These  conditions  were  partially  offset by
operating   income   attributable   to  2002   acquisitions,   an   increase  in
transportation  infrastructure,  healthcare and institutional  projects,  and an
increase in certain  other  longer-term  projects in both the United  States and
Canada, as well as operating income from the United States  facilities  services
markets.

United States electrical  construction and facilities  services operating income
for the three months ended June 30, 2003 was $16.2  million or 5.0% of revenues,
compared to $14.5  million or 5.0% of revenues  for the three  months ended June
30,  2002.  Operating  income for the six months  ended June 30,  2003 was $29.1
million,  or 5.1% of revenues,  compared to $30.9 million,  or 5.4% of revenues,
for the six months ended June 30, 2002.  The operating  income  increase of $1.7
million for the three months ended June 30, 2003  compared to the prior year was
primarily attributable to certain transportation  infrastructure projects and to
close-outs  and  continuing  work on power  generation  projects.  The operating
income  decrease of $1.8  million for the six month  period  ended June 30, 2003
compared to the same period in the prior year was attributable to a reduction in
discretionary  spending in the commercial  office and industrial  markets due to
the  economic   slow-down,   partially  offset  by  positive   operating  income
contributed by the transportation infrastructure and power generation projects.

United States mechanical  construction and facilities  services operating income
for the three  months  ended June 30, 2003 was $6.2 million or 1.5% of revenues,
compared to $19.2  million or 4.4% of revenues  for the three  months ended June
30,  2002.  Operating  income for the six months  ended June 30,  2003 was $10.6
million,  or 1.3% of revenues,  compared to $25.9 million,  or 3.5% of revenues,
for the six months  ended June 30, 2002.  The  decrease in operating  income for
both the  three  and six month  periods  ended  June 30,  2003  compared  to the
comparable prior year periods was primarily attributable to certain construction
operations which  experienced  reductions in operating income due to a reduction
in  discretionary  spending related to the economic  slow-down,  a change in the
type of work performed to longer-term  construction  projects that generally has
produced lower gross profits than fast-track  commercial work and a reduction in
the demand for services as a result of cooler than normal weather  conditions in
the United States.

United  States  facilities  services  operating  income was $4.6 million for the
three  months ended June 30, 2003  compared to operating  income of $0.3 million
for the three months ended June 30, 2002. For the six months ended June 30, 2003
and 2002,  operating  income was $6.7  million  and  operating  losses were $0.5
million,  respectively.  The increase in operating income for the 2003 three and
six  month  periods  compared  to the  first  and  second  quarter  of 2002  was
attributable to operating income of $4.1 million and $6.1 million, respectively,
earned by  companies  acquired in 2002 and to operating  income from  site-based
facilities management contracts in this segment,  partially offset by a decrease
in mobile  maintenance  services  related  to the  cooler  than  normal  weather
conditions in the United States and a decrease in discretionary spending related
to the economic  slow-down,  as well as certain costs related to the integration
of CES.

Canada  construction and facilities  services  operating income was $1.1 million
for the three months ended June 30, 2003, compared to $0.7 million for the three
months  ended June 30, 2002.  For the six months ended June 30, 2003,  operating
income was $1.8  million  compared to  operating  income of $0.2 million for the
same period in the prior year.  The  increase in  operating  income for both the
three and six month  periods was  primarily  due to operating  income  earned on
continuing longer-term power generation construction projects.

United Kingdom  construction  and facilities  services  operating losses for the
three months ended June 30, 2003 were $2.9 million  compared to operating income
of $0.7 million for the same period in the prior year.  For the six months ended
June 30, 2003,  operating losses were $7.3 million compared to an operating loss
of $0.3 million for the same period in the prior year. The increase in operating
loss for the three and six  months  ended  June 30,  2003  compared  to the same
periods in 2002 was  attributable  to unfavorable performance,  settlements  and
close-outs on certain  projects which offset  operating income earned on certain
projects in the construction and facilities services markets.


Other  international  construction and facilities services operating losses were
$0.3  million for the three  months  ended June 30, 2003  compared to  operating
income of $0.2 million for three months ended June 30, 2002.  For the six months
ended  June 30,  2003 and 2002,  operating  losses  were $0.1  million  for both
periods.  EMCOR continues to selectively  pursue new business in the Middle East
and South Africa as well as Continental  Europe;  however,  the  availability of
opportunities  has been  significantly  reduced  as a result  of local  economic
factors.

General  corporate  expense  for the three  months  ended June 30, 2003 was $8.3
million  compared to $8.6 million for the three months ended June 30, 2002.  For
the six months ended June 30, 2003,  general corporate expense was $16.5 million
compared to $16.6 million for the same period in the prior year. The decrease in
general corporate expenses was primarily due to cost reductions  attributable to
reduced variable expenditures, offset by increased operations support activities
related to the  management and  integration  of more than 30 companies  acquired
during 2002.

Interest  expense  for the three  months  ended June 30,  2003 and 2002 was $2.0
million  and $0.8  million,  respectively.  Interest  expense for the six months
ended June 30, 2003 and 2002 was $4.0  million and $1.3  million,  respectively.
The  increase in interest  expense for both the three and six month  periods was
primarily due to $156.0 million of borrowings  under the working  capital credit
line for the  acquisition  of CES on December 19, 2002 and to increased  working
capital needs  related to a shift to increased  revenues  from  longer-term  new
construction  projects  which  typically  require  working  capital during their
inception  until  initial  billing  milestones  are  achieved.  Interest  income
decreased  $0.2 million and $0.9 million for the three and six months ended June
30, 2003,  respectively,  compared to the same periods in 2002 due to lower cash
on hand  related to cash used to pay a portion of the CES  acquisition  price in
December 2002 and cash used in operating activities.


The income tax  provision  decreased  to $6.5 million for the three months ended
June 30, 2003 compared to $11.7 million for the same period in 2002. For the six
months ended June 30, 2003,  the income tax  provision  was $9.1 million  versus
$17.3  million for the six months  ended June 30,  2002.  The  decreases in this
provision  compared to the prior periods were  primarily  due to reduced  income
before taxes. The effective income tax rate was  approximately  44% for both the
three and six months ended June 30, 2003 and 2002.

EMCOR's  contract  backlog was $3.2 billion at June 30, 2003 and $2.9 billion at
December 31, 2002. The $0.3 billion  increase in backlog was primarily due to an
increase in backlog for the United States and the United Kingdom.

EMCOR's  contract  backlog at June 30,  2003 was $3.2  billion  compared to $2.8
billion at June 30, 2002. The increase was primarily  attributable to backlog of
$0.2 billion for CES subsidiaries  acquired in 2002 and net growth in backlog of
$0.2 billion from contracts awarded to other  subsidiaries in the United States,
the United Kingdom and Canada.

Net cash provided by (used in) financing activities     $ 34,115      $    (288)


EMCOR's  consolidated cash balance decreased by approximately $35.4 million from
$93.1 million at December 31, 2002 to $57.8  million at June 30, 2003.  Net cash
used in operating  activities of $53.1 million for the six months ended June 30,
2003 was a $121.2  million  decrease  from the net cash  provided  by  operating
activities  of $68.1  million in the same period last year.  The increase in net
cash used in operating  activities was primarily  attributable to a net increase
in working capital  requirements  related to a decrease in accounts  payable and
contracts in progress,  partially  offset by a decrease in accounts  receivable.
Net cash used in  investing  activities  of $16.3  million  decreased  by $151.5
million compared to $167.8 million in the same period last year. The decrease in
cash used in  investing  activities  was due  primarily  to  payments  of $164.6
million for the acquisition of the Acquired Comfort  Companies in the first half
of 2002 and a  decrease  in  EMCOR's  investments,  notes  and  other  long-term
receivables in the first half of 2002 compared to an increase in this account in
the first half of 2003.  Net cash  provided  by  financing  activities  of $34.1
million represented a $34.4 million increase from the net cash used in financing
activities of $0.3 million for the six months ended June 30, 2002.  The increase
in net cash provided by financing  activities was attributable to an increase in
borrowings  under working capital credit lines,  partially offset by a reduction
in net repayments of long-term debt and capital lease payments.

(1)  Represent  open  purchase  orders for  material  and  subcontracting  costs
     related to the Company's construction and service contracts. These purchase
     orders are not reflected in EMCOR's  consolidated  balance sheet and should
     not impact future cash flows as amounts will be recovered  through customer
     billings.
(2)  Represent  primarily  insurance related  liabilities,  the timing for which
     payments beyond one year is not practical to estimate.
(3)  EMCOR classifies these borrowings as short-term on its consolidated balance
     sheet  because of  EMCOR's  intent  and  ability to repay the  amounts on a
     short-term basis. The revolving credit facility expires in September 2007.

As of June 30, 2003, EMCOR's total borrowing capacity under its revolving credit
facility was $296.0 million. EMCOR had approximately $50.3 million of letters of
credit  outstanding  under the revolving  credit  facility as of that date.  The
amount of borrowings  outstanding under the revolving credit facility as of June
30,  2003 and  December  31,  2002  were  $166.8  million  and  $112.0  million,
respectively.  Effective  July 9,  2003,  EMCOR  increased  its total  borrowing
capacity under its revolving credit facility to $350.0 million.

A subsidiary of EMCOR has guaranteed indebtedness of a venture in which it has a
40% interest;  the other venture partner,  Baltimore Gas and Electric, has a 60%
interest. The venture designs,  constructs, owns, operates, leases and maintains
facilities  to  produce  chilled  water  for  sale to  customers  for use in air
conditioning of commercial properties. These guarantees are not expected to have
a material effect on EMCOR's financial  position or results of operations.  Each
of the venturers is jointly and severally liable,  in the event of default,  for
the venture's $25.0 million  borrowing due December 2031. During September 2002,
each  venture  partner  contributed  equity  to the  venture,  of which  EMCOR's
contribution was $14.0 million.

There are $0.6  million in current  maturities  of  EMCOR's  long-term  debt and
capital lease obligations as of June 30, 2003.

EMCOR is  contingently  liable to sureties in respect of performance and payment
bonds issued by sureties, usually at the request of customers in connection with
construction  projects  which secure EMCOR payment and  performance  obligations
under contracts for such projects.  In addition,  at the request of labor unions
representing  certain EMCOR  employees,  bonds are sometimes  provided to secure
obligations for wages and benefits payable to or for such employees.  As of June
30, 2003 and  December  31,  2002,  sureties had issued bonds for the account of
EMCOR in the aggregate amount of approximately $2.1 billion.  To the extent such
bonds were for the benefit of customers  (as distinct from labor  unions),  they
related to approximately  1,100 construction  projects.  The bonds are issued by
EMCOR's  sureties in return for a premium  which can vary  depending on the size
and type of the bonds.  The  largest  individual  bond is  approximately  $170.0
million.  EMCOR has agreed to indemnify  the  sureties for any payments  made by
them in respect of bonds issued on EMCOR's behalf.

EMCOR does not have any other material financial guarantees or off-balance sheet
arrangements other than those disclosed herein.

The primary  source of liquidity for EMCOR has been, and is expected to continue
to be, cash generated by operating activities.  EMCOR also maintains a revolving
credit  facility that may be utilized,  among other things,  to meet  short-term
liquidity  needs  in  the  event  cash  generated  by  operating  activities  is
insufficient,  or to enable EMCOR to seize opportunities to participate in joint
ventures or to make acquisitions that may require access to cash on short notice
or for any other  reason.  EMCOR may also increase  liquidity  through an equity
offering or other debt instruments.  Short-term changes in macroeconomic  trends
may have an affect,  positively or negatively,  on liquidity. In order to manage
through these  uncertainties,  EMCOR currently has the capacity to borrow funds,
if  necessary,  to  meet  short-term  requirements.   In  addition  to  managing
borrowings,  EMCOR's  focus on the  facilities  services  market is  intended to
provide an  additional  buffer  against  economic  downturns  as the  facilities
services market is characterized by annual and multi-year contracts that provide
a more  predictable  stream of cash  flows  than the  construction  market.  The
acquisition  of  CES  in  December  2002,  which  is  primarily  focused  on the
facilities  services  market,  is part of  EMCOR's  plan to grow its  facilities
services business.  Short-term liquidity is also impacted by the type and length
of construction contracts in place. During economic downturns,  such as the 2001
through  2003  period,   construction  contracts  trend  away  from  short-cycle
contracts toward larger longer-term  infrastructure and public sector contracts.
Performance of longer  duration  contracts  typically  require  working  capital
during their  inception  until initial  billing  milestones are achieved.  While
EMCOR strives to maintain a net over-billed  position with its customers,  there
can be no assurance that a net over-billed  position can be maintained.  EMCOR's
net  over-billings,  defined as the balance sheet accounts billings in excess of
costs and estimated  earnings on  uncompleted  contracts less cost and estimated
earnings in excess of billings on uncompleted contracts,  was $121.4 million and
$127.3 million as of June 30, 2003 and December 31, 2002, respectively.

Long-term  liquidity  requirements  can  be  expected  to be  met  through  cash
generated from operating activities, the revolving credit facility, and the sale
of various  secured or unsecured debt and/or equity  interests in the public and
private  markets.  Based upon  EMCOR's  current  credit  ratings  and  financial
position,  EMCOR  can  reasonably  expect  to be able to  issue  long-term  debt
instruments  and/or equity.  Over the long term,  EMCOR's  primary  revenue risk
factor  continues  to be the level of demand  for  non-residential  construction
services, which is in turn influenced by macroeconomic trends including interest
rates and governmental  economic policy. In order to provide  protection against
demand cycles in private sector construction  services,  EMCOR has increased its
participation,  and its backlog of  contracts,  in the public  sector and in the
facilities services market.

EMCOR believes that current cash balances and borrowing capacity available under
existing lines of credit or other forms of financing  available  through debt or
equity  offerings,  combined with cash expected to be generated from operations,
will be sufficient to provide short-term and foreseeable long-term liquidity and
meet expected capital  expenditure  requirements.  However,  EMCOR is a party to
lawsuits and other  proceedings  in which other  parties seek to recover from it
amounts ranging from a few thousand dollars to over $60.0 million.  If EMCOR was
required to pay damages in one or more such  proceedings,  such  payments  could
have a material adverse effect on its cash flow and/or earnings.






Certain Insurance Matters

As of June 30, 2003 and December 31, 2002,  EMCOR utilized  approximately  $31.2
million and $24.5 million, respectively, of letters of credit issued pursuant to
its revolving credit facility as collateral for its insurance obligations.

Application of Critical Accounting Policies

The condensed  consolidated financial statements are based on the application of
significant  accounting  policies,  which require management to make significant
estimates and assumptions. EMCOR's significant accounting policies are described
in  Note  B -  Summary  of  Significant  Accounting  Policies  of the  notes  to
consolidated  financial  statements  included in Item 8 of its annual  report on
Form 10-K for the year ended December 31, 2002. There was no initial adoption of
any  accounting  policies  during the three and six months  ended June 30,  2003
other than those  listed  under "New  Accounting  Pronouncements"  below.  EMCOR
believes that some of the more critical  judgment  areas in the  application  of
accounting   policies  that  affect  its  financial  condition  and  results  of
operations  are estimates and  judgments  pertaining to (a) revenue  recognition
from (i) long term construction contracts for which the percentage of completion
method of accounting is used and (ii) services contracts,  (b) collectibility or
valuation of accounts receivable,  (c) insurance  liabilities,  (d) income taxes
and (e) intangible assets.

Revenue Recognition for Long-term Construction Contracts and Services Contracts

EMCOR believes its most critical  accounting policy is revenue  recognition from
long-term     construction     contracts    for    which    EMCOR    uses    the
percentage-of-completion   method   of   accounting.    Percentage-of-completion
accounting is the  prescribed  method of accounting  for long-term  contracts in
accordance with accounting  principles  generally accepted in the United States,
Statement of Position No. 81-1,  "Accounting  for  Performance of Construction -
Type and Certain Production - Type Contracts" and, accordingly,  the method used
for revenue  recognition within EMCOR's industry.  Percentage-of-completion  for
each contract is measured principally by the ratio of costs incurred to date for
each  contract to the  estimated  total costs for such  contract at  completion.
Certain   of   EMCOR's   electrical    contracting    business   units   measure
percentage-of-completion  by the  percentage of labor costs incurred to date for
each contract to the estimated  total labor costs for such contract.  Provisions
for the entirety of estimated  losses on  uncompleted  contracts are made in the
period   in   which    such    losses    are    determined.    Application    of
percentage-of-completion  accounting  results  in the  recognition  of costs and
estimated  earnings in excess of billings on  uncompleted  contracts  in EMCOR's
consolidated  balance sheets. Costs and estimated earnings in excess of billings
on uncompleted contracts reflected in the consolidated balance sheets arise when
revenues have been  recognized  but the amounts cannot be billed under the terms
of contracts.  Such amounts are recoverable from customers upon various measures
of  performance,  including  achievement  of certain  milestones,  completion of
specified  units or  completion of a contract.  Costs and estimated  earnings in
excess of billings on uncompleted  contracts also include amounts EMCOR seeks or
will seek to collect from  customers or others for errors or changes in contract
specifications or design,  contract change orders in dispute or unapproved as to
both  scope  and  price,  or  other  customer-related  causes  of  unanticipated
additional contract costs. Such amounts are recorded at estimated net realizable
value and take into  account  factors  that may affect  the  ability to bill and
collect amounts billed. Due to uncertainties  inherent within estimates employed
to  apply  percentage-of-completion  accounting,  estimates  may be  revised  as
project work  progresses.  Application  of  percentage-of-completion  accounting
requires  that  the  impact  of  those  revised  estimates  be  reported  in the
consolidated financial statements prospectively.

In addition to revenue recognition for long-term construction  contracts,  EMCOR
recognizes  revenues from services  contracts as these services are performed in
accordance  with Staff  Accounting  Bulletin No. 101,  "Revenue  Recognition  in
Financial  Statements" ("SAB 101").  There are two basic types of services:  (1)
those provided  pursuant to fixed price services  contracts  which are signed in
advance for  operation  and  maintenance  services  work over periods  typically
ranging  from one to three years (for which EMCOR  employees  may be assigned to
the  customer's  site full time) and (2)  services  for  similar  operation  and
maintenance  services work performed on an as needed basis. Fixed price services
contracts  are  generally   performed  evenly  over  the  contract  period,  and
accordingly,  revenue is  recognized  on a  pro-rata  basis over the term of the
contract.  Revenues derived from other services are recognized when the services
are  rendered  in  accordance  with SAB 101.  Expenses  related  to all  service
contracts are recognized as services are provided.

Accounts Receivable

EMCOR is required to  estimate  the  collectibility  of accounts  receivable.  A
considerable  amount of judgment is required in  assessing  the  realization  of
receivables,  which  assessment  factors  include  the  creditworthiness  of the
customer,  EMCOR's prior collection  history with the customer and related aging
of the past due  balances.  At June 30, 2003 and  December  31,  2002,  accounts
receivable  of  $986.3  million  and  $965.0  million,  respectively,   included
allowances of $40.3 million and $40.6 million,  respectively.  Specific accounts
receivable  are evaluated when EMCOR believes a customer may not be able to meet
its financial  obligations  due to a deterioration  of its financial  condition,
credit ratings or bankruptcy.  The allowance  requirements are based on the best
facts available and are re-evaluated  and adjusted as additional  information is
received.

Insurance Liabilities

EMCOR has deductibles for certain workers' compensation, auto liability, general
liability and property  claims,  has  self-insured  retentions for certain other
casualty claims,  and is self-insured for  employee-related  health care claims.
Losses are recorded  based upon  estimates of the liability for claims  incurred
and an estimate of claims incurred but not reported. The liabilities are derived
from  known  facts,  historical  trends  and  industry  averages  utilizing  the
assistance of an actuary to determine  the best  estimate of these  obligations.
EMCOR believes its liabilities for these obligations are adequate. However, such
obligations  are  difficult  to assess and  estimate  due to  numerous  factors,
including severity of injury,  determination of liability in proportion to other
parties,  timely  reporting of occurrences and  effectiveness of safety and risk
management   programs.   Therefore,   if  actual  experience  differs  from  the
assumptions and estimates used for recording the liabilities, adjustments may be
required and recorded in the period that the experience becomes known.

Income Taxes

EMCOR has net deferred tax assets primarily resulting from deductible  temporary
differences,  which will reduce  taxable income in future  periods.  A valuation
allowance is required when it is more likely than not that all or a portion of a
deferred  tax asset will not be  realized.  As of June 30, 2003 and December 31,
2002, the total valuation allowance on net deferred tax assets was approximately
$2.1 million.

Intangible Assets

As of June 30, 2003, EMCOR had goodwill and net identifiable  intangible  assets
of $293.9  million  and $12.1  million,  respectively,  in  connection  with the
acquisition of certain companies.  The determination of related estimated useful
lives for identifiable  intangible  assets and whether those assets are impaired
involves  significant  judgments  based upon short and long-term  projections of
future performance. Certain of these forecasts reflect assumptions regarding the
ability to successfully  integrate  acquired  companies.  Statement of Financial
Accounting  Standards No. 142,  "Goodwill and Other  Intangible  Assets"  ("SFAS
142") requires goodwill to be tested for impairment under certain circumstances,
and  written  down when  impaired,  rather  than  being  amortized  as  previous
standards  required.  Furthermore,  SFAS 142  requires  identifiable  intangible
assets other than goodwill to be amortized  over their useful lives unless their
lives are  determined  to be  indefinite.  Changes  in  strategy  and/or  market
conditions may result in adjustments to identifiable  intangible asset balances.
As of June 30,  2003,  no  indicators  of  impairment  of  EMCOR's  goodwill  or
identifiable intangible assets existed in accordance with the provisions of SFAS
142.

New Accounting Pronouncements

In November 2002, the Financial  Accounting  Standards Board (the "FASB") issued
Financial   Accounting  Standards  Board  Interpretation  No.  45,  "Guarantor's
Accounting  and  Disclosure  Requirements  for  Guarantees,  Including  Indirect
Guarantees of Indebtedness of Others,  an  Interpretation of FASB Statements No.
5, 57, and 107 and  Rescission of FASB  Interpretation  No. 34" ("FIN 45" or the
"Interpretation").  FIN 45  clarifies  the  requirements  of FASB  Statement  of
Financial Accounting  Standards No. 5, "Accounting for Contingencies,"  relating
to the  guarantor's  accounting  for, and disclosure of, the issuance of certain
types of guarantees.  FIN 45 may require, that upon issuance of a guarantee, the
guarantor  to  recognize a  liability  for the fair value of the  obligation  it
assumes under the guarantee.  The disclosure  provisions of the  Interpretations
are  effective for  financial  statements of interim or annual  periods that end
after December 15, 2002. The Interpretation's provisions for initial recognition
and measurement should be applied on a prospective basis to guarantees issued or
modified  after  December  31,  2002,  irrespective  of the  guarantor's  fiscal
year-end.  The guarantor's  previous  accounting for guarantees that were issued
before the date of FIN 45's initial  application  may not be revised or restated
to reflect  the effect of the  recognition  and  measurement  provisions  of the
Interpretation.  EMCOR  has  determined  that the  adoption  of FIN 45 will only
impact its disclosures and that its accounting for guarantees is not impacted as
of June 30, 2003.

In January 2003, the FASB issued Statement of Financial Accounting Standards No.
148,  "Accounting  for  Stock-Based  Compensation - Transition  and  Disclosure"
("SFAS 148"). SFAS 148 amends FASB Statement of Financial  Accounting  Standards
No. 123,  "Accounting  for  Stock-Based  Compensation"  ("SFAS  123") to provide
alternative methods of transition for a voluntary change to the fair value based
method of accounting for stock-based employee  compensation.  In addition,  SFAS
148  amends  the  disclosure  requirements  of  SFAS  123 to  require  prominent
disclosures  in both annual and interim  financial  statements  of the method of
accounting for stock-based  employee  compensation  and the effect of the method
used on reported  results.  SFAS 148 was  effective  for fiscal years  beginning
after  December  15, 2002 and was  adopted by EMCOR for all  periods  presented.
EMCOR  did  not  change  to the  fair  value  based  method  of  accounting  for
stock-based employee compensation, and accordingly, adoption of SFAS 148 impacts
only disclosures, not the financial results, of EMCOR.

In January  2003,  the FASB  issued  Interpretation  No. 46,  "Consolidation  of
Variable  Interest  Entities"  ("FIN 46").  FIN 46 expands upon and  strengthens
existing accounting guidance that addresses when a company should include in its
financial statements the assets, liabilities and activities of another entity. A
variable  interest  entity is a corporation,  partnership,  trust,  or any other
legal structure used for business  purposes that either (a) does not have equity
investors  with voting  rights or (b) has equity  investors  that do not provide
sufficient financial resources for the entity to support its activities.  FIN 46
requires  a variable  interest  entity to be  consolidated  by a company if that
company is subject to a majority of the risk of loss from the variable  interest
entity's  activities  or is  entitled  to  receive a  majority  of the  entity's
residual  returns or both.  FIN 46 is effective  for all new  variable  interest
entities  created or acquired  after  January 31, 2003.  For  variable  interest
entities created or acquired prior to February 1, 2003, the provisions of FIN 46
must be applied for the first interim or annual period  beginning after June 15,
2003. EMCOR is currently evaluating the effect that adoption of FIN 46 will have
on EMCOR's consolidated financial condition or results of operations.

In April 2003, the FASB issued Statement of Financial  Accounting  Standards No.
149,  "Amendment  of  Statement  133  on  Derivative   Instruments  and  Hedging
Activities"  ("SFAS  149").  SFAS  149  amends  and  clarifies   accounting  for
derivative  instruments,  including certain derivative  instruments  embedded in
other  contracts,  and for hedging  activities  under SFAS 133. The new guidance
amends  SFAS  133  for  decisions   made:   (a)  as  part  of  the   Derivatives
Implementation  Group process that effectively  required amendments to SFAS 133,
(b) in connection with other Board projects dealing with financial  instruments,
and (c) regarding implementation issues raised in relation to the application of
the  definition of a derivative.  The  amendments  set forth in SFAS 149 improve
financial reporting by requiring that contracts with comparable  characteristics
be accounted  for  similarly.  SFAS 149 is  generally  effective  for  contracts
entered  into or  modified  after June 30,  2003 and for  hedging  relationships
designated  after June 30, 2003. It is not expected that the  provisions of SFAS
149 will have a material  impact on  EMCOR's  consolidated  financial  position,
results of operations or cash flows.

In May 2003,  the FASB issued  Statement of Financial  Accounting  Standards No.
150, "Accounting for Certain Financial  Instruments with Characteristics of Both
Liabilities  and Equity"  ("SFAS  150").  SFAS 150  requires  certain  financial
instruments that embody  obligations of the issuer and have  characteristics  of
both  liabilities and equity to be classified as liabilities.  The provisions of
SFAS 150 are effective for financial  instruments entered into or modified after
May 31, 2003 and to all other  instruments that exist as of the beginning of the
first interim  financial  reporting  period beginning after June 15, 2003. EMCOR
does not have any financial  instruments  that meet the  provisions of SFAS 150;
therefore,  adopting  the  provisions  of  SFAS  150 is not  expected  to have a
material  impact  on  EMCOR's  consolidated   financial  position,   results  of
operations or cash flows.

This Quarterly Report on Form 10-Q contains certain  forward-looking  statements
within the meaning of the Private  Securities  Reform Act of 1995,  particularly
statements  regarding  market  opportunities,  market share growth,  competitive
growth, gross profit, and selling,  general and administrative  expenses.  These
forward-looking  statements  involve  risks and  uncertainties  that could cause
actual  results  to differ  materially  from  those in any such  forward-looking
statements.  Such risk and uncertainties include, but are not limited to adverse
changes in  general  economic  conditions,  including  changes  in the  specific
markets for EMCOR's services, adverse business conditions,  decreased or lack of
growth in the  mechanical and electrical  construction  and facilities  services
industries,  increased  competition,  pricing  pressures,  risks associated with
foreign operations and other factors.

ITEM 3. QUANTITATIVE AND QUALITATIVE DISCLOSURES ABOUT MARKET RISK

EMCOR has not used derivative  financial  instruments for any purpose during the
three  and six  months  ended  June 30,  2003 and  2002,  including  trading  or
speculating on changes in interest  rates or commodity  prices of materials used
in its business.

EMCOR is exposed to market  risk for changes in  interest  rates for  borrowings
under its revolving credit  facility.  Borrowings under the credit facility bear
interest  at  variable  rates,  and the  fair  value  of this  borrowing  is not
significantly affected by changes in market interest rates. As of June 30, 2003,
there were $166.8 million of borrowings  outstanding  under the revolving credit
facility,  and these  borrowings  bear interest at (1) a rate which is the prime
commercial  lending rate announced by Harris Trust and Savings Bank from time to
time (4.00% at June 30, 2003) plus 0% to 1.0% based on certain  financial  tests
or (2) at a LIBOR  rate  (1.12% at June 30,  2003)  plus  1.5% to 2.5%  based on
certain  financial  tests.  Based on borrowings of $166.8  million,  if interest
rates were to increase by 1.0%,  the net of tax interest  expense would increase
$1.0 million in the next twelve  months.  Conversely,  if interest rates were to
decrease by 1.0%, interest expense would decrease by $1.0 million in the next 12
months.  The revolving  credit facility  expires in September 2007.  There is no
guarantee that EMCOR will be able to renew the facility at its expiration.


EMCOR is also  exposed  to  market  risk and its  potential  related  impact  on
accounts  receivable  or costs and  estimated  earnings in excess of billings on
uncompleted contracts. The amounts recorded may be at risk if customers' ability
to pay these obligations is negatively  impacted by economic  conditions.  EMCOR
continually  monitors  the  creditworthiness  of  its  customers  and  maintains
on-going  discussions with customers  regarding  contract status with respect to
change orders and billing terms. Therefore,  EMCOR believes it takes appropriate
action to manage market and other risks,  but there is no assurance that it will
be able to reasonably identify all risks with respect to collectibility of these
assets.  See also the  previous  discussion  of  Accounts  Receivable  under the
heading,  "Application  of Critical  Accounting  Policies"  in the  Management's
Discussion and Analysis of Results of Operations and Financial Condition.

Amounts invested in EMCOR's foreign operations are translated into U. S. dollars
at the  exchange  rates  in  effect  at the  end of the  period.  The  resulting
translation  adjustments are recorded as accumulated other comprehensive  income
(loss),  a component of  stockholders'  equity,  in its  condensed  consolidated
balance  sheets.  EMCOR  believes the  exposure to the effects that  fluctuating
foreign currencies may have on its consolidated results of operations is limited
because  the  foreign   operations   primarily  invoice  customers  and  collect
obligations  in  their  respective  local  currencies.   Additionally,  expenses
associated with these transactions are generally  contracted and paid for in the
same local currencies.

ITEM 4. CONTROLS AND PROCEDURES

Based on an evaluation of EMCOR's disclosure controls and procedures (as defined

                       FIRST AMENDMENT TO CREDIT AGREEMENT




To the Lenders Party to the Credit
  Agreement identified below

Ladies and Gentlemen:

     We refer to the Credit Agreement dated as of September 26, 2002 among EMCOR
Group,   Inc.  a  Delaware   corporation,   Comstock  Canada  Ltd.,  a  Canadian
corporation,  and EMCOR Drake & Scull Group plc., a United  Kingdom  corporation
(collectively the  "Borrowers"),  Harris Trust and Savings Bank as Agent for the
Lenders and the  financial  institutions  from time to time  parties  thereto as
Lenders,  all as  amended  and  currently  in  effect  between  us (the  "Credit
Agreement").  Capitalized  terms  used  herein  without  definition  to have the
meanings ascribed to them in the Credit Agreement.

     The Borrowers have requested that the Lenders amend the Credit Agreement in
order to add a new credit  facility to be made  available  in the form of Excess
Revolving Loans, and make certain other amendments to the Credit Agreement,  and
the  Lenders are  willing to do so under the terms and  conditions  set forth in
this Agreement (herein, the "Amendment").

SECTION 1.  ADDITION OF EXCESS COMMITMENT LENDERS.

     Upon the effectiveness of this Amendment, each of Bank of Montreal, Chicago
Branch ("BMO"), LaSalle Bank National Association ("LaSalle") and Fleet National
Bank ("Fleet";  BMO,  LaSalle and Fleet are each referred to in their respective
capacities  as Excess  Commitment  Lenders  herein  individually  as an  "Excess
Commitment  Lender" and collectively as the "Excess  Commitment  Lenders") shall
become an Excess Commitment Lender party to the Credit Agreement and be deemed a
"Lender"  signatory  to the  Credit  Agreement  and shall  have all the  rights,
benefits duties and obligations of a "Lender" under the Credit  Agreement except
as otherwise specified herein.  Except as otherwise specified in Section 1.10 of
the Credit  Agreement as amended hereby,  all references in the Credit Agreement
and the Loan  Documents to the term  "Lender" and  "Lenders"  shall be deemed to
include and be a reference to the Excess Commitment Lenders.  The amount of each
Excess  Commitment  Lender's Excess  Commitment is the amount set forth opposite
such Excess Commitment  Lender's name on Schedule I hereto.  The address and the
lending  office  that  appears on BMO's  signature  page  hereto  shall be BMO's
address and lending office for all purposes of the Credit Agreement.

     The Company hereby agrees to execute and deliver to each Excess  Commitment
Lender a Note in the principal amount equal to such Excess  Commitment  Lender's
Excess Commitment.

SECTION 2.  AMENDMENTS.

     Subject  to the  satisfaction  of the  conditions  precedent  set  forth in
Section  3 below,  the  Credit  Agreement  shall be and  hereby is  amended  and
supplemented as follows:

2.1. The Credit Agreement is hereby amended by adding thereto a new Section 1.10
     which reads as follows:

     1.10. Excess Commitment.

          (a)  Generally.  Subject  to all of the terms and  conditions  hereof,
               each  Excess  Commitment   Lender,  by  its  acceptance   hereof,
               severally  agrees to make  Revolving  Loans to the Company in the
               amount of its Excess  Commitment  set forth  opposite its name on
               Schedule 1.1 hereof (its "Excess Commitment" and cumulatively for
               all of the Excess Commitment Lenders,  the "Excess  Commitments")
               from  time to time  prior to the  Excess  Commitment  Termination
               Date.  Subject  to the terms and  conditions  hereof,  the Excess
               Commitments  may be availed of by the  Company in its  discretion
               from time to time,  be repaid and used  again,  during the period
               from and  including  June 2,  2003 to and  including  the  Excess
               Commitment  Termination Date. The Excess  Commitment,  subject to
               all of the terms and conditions hereof, may be utilized solely by
               the  Company  in the form of  Revolving  Loans all as more  fully
               hereinafter  set forth;  provided,  however,  that the  aggregate
               amount of the Revolving Loans  outstanding at any one time to the
               Company  from  the  Excess  Commitment  Lenders  shall at no time
               exceed  the Excess  Commitments.  The  obligations  of the Excess
               Commitment  Lenders  hereunder  are  several and not joint and no
               Excess   Commitment  Lender  shall  under  any  circumstances  be
               obligated to extend credit in excess of its Excess Commitment. In
               addition,  in no event  shall any  Lender  other  than the Excess
               Commitment Lenders have any obligation to extend credit under the
               Excess Commitments.

          (b)  Excess  Revolving  Loans.   Subject  to  all  of  the  terms  and
               conditions  hereof, the Excess Commitments shall be availed of by
               the Company solely in the form of loans  (individually an "Excess
               Revolving Loan" and collectively the "Excess  Revolving  Loans").
               Each  Borrowing of Excess  Revolving  Loans shall,  except to the
               extent otherwise agreed by all Excess Commitment Lenders, be made
               ratably by the Excess Commitment Lenders in accordance with their
               respective Excess  Commitments and not by any other Lender.  Each
               Borrowing  of Excess  Commitment  Loans  shall be in the  minimum
               amount  specified in Section 1.5 hereof for Revolving  Loans. All
               Excess Revolving Loans made by an Excess Commitment Lender to the
               Company  shall be evidenced by a single Excess  Revolving  Credit
               Note of the Company (individually an "Excess Commitment Note" and
               collectively the "Excess  Commitment Notes") payable to the order
               of such Excess  Commitment  Lender,  each such  Excess  Revolving
               Credit  Note  to be in the  form  (with  appropriate  insertions)
               attached  hereto  as  Exhibit  A-3.  Without  regard  to the face
               principal  amount  of any  Excess  Commitment  Note,  the  actual
               principal amount at any time outstanding and owing by the Company
               on  account  of Excess  Revolving  Loans  shall be the sum of all
               Excess  Revolving Loans then or theretofore  made thereon by such
               Excess  Commitment  Lender  to the  Company,  less  all  payments
               actually received thereon.

          (c)  Conditions Precedent to Excess Revolving Loans. The obligation of
               the Excess Commitment  Lenders to make any Excess Revolving Loans
               (including the first Excess  Revolving  Loan) shall be subject to
               the conditions  precedent that as of the time of each such Excess
               Revolving Loan:

               (i)  Each of the  conditions  precedent  set forth in Section 6.1
                    hereof  shall  be  satisfied  with  respect  to such  Excess
                    Revolving Loan;

               (ii) After  giving  effect to such  Excess  Revolving  Loan,  the
                    aggregate  principal  amount of all Excess  Revolving  Loans
                    shall not  exceed the Excess  Revolving  Commitment  then in
                    effect; and

               (iii)The Revolving  Loan  Availability  immediately  prior to the
                    making of such Excess  Revolving  Loan is less than or equal
                    to $5,000,000.

     Any request  made by or on behalf of the Company to the Agent for an Excess
Revolving Loan shall be deemed to constitute a representation  and warranty that
the foregoing statements are true and correct.

          (d)  Manner of Borrowing  Excess  Revolving  Loans.  The Company shall
               give the Agent  notice  (which  shall be  irrevocable  and may be
               written or oral, but if oral,  promptly  confirmed in writing) by
               10:00 a.m. (central time) on any Business Day of each request for
               a Borrowing of Excess Revolving  Loans, in each case,  specifying
               the amount of such  Borrowing,  the date such  Borrowing is to be
               made,  which shall not be less than three (3) Business Days hence
               in the case of a Borrowing of Eurodollar  Loans, but which may be
               the same day in the case of a Borrowing of a Domestic Rate Loans,
               whether  the  Borrowing  is to  be  of  Domestic  Rate  Loans  or
               Eurodollar  Loans and,  in all cases  other than a  Borrowing  of
               Domestic Rate Loans, of the Interest  Period  selected  therefor.
               The Agent shall promptly notify each Excess  Commitment Lender of
               its receipt of such notice.  Not later than 1:00 p.m. on the date
               specified  for any  Borrowing  of Excess  Revolving  Loans,  each
               Excess  Commitment  Lender shall make the proceeds of such Excess
               Revolving Loan  comprising  part of such  Borrowing  available in
               immediately  available  funds to the Agent in Chicago,  Illinois.
               Borrowings  under the  Excess  Commitments  shall be made in U.S.
               Dollars  only.  As between the Agent and each  Excess  Commitment
               Lender, the provisions of Section 1.4(b) shall be deemed to apply
               to any Borrowing of Excess Revolving Loans.

          (e)  Maturity  Date.  The Excess  Commitments  shall  immediately  and
               automatically  terminate  and each  Excess  Revolving  Loan shall
               mature  and  become  due and  payable  on the  Excess  Commitment
               Termination Date.

          (f)  Credit  Agreement  Provisions.  Except as otherwise  set forth in
               this Section 1.10,  the following  provisions  shall apply to the
               Excess  Commitment,  the Excess  Commitment  Lenders,  the Excess
               Commitment  Notes and the Excess Revolving Loans for the purposes
               of the Credit Agreement:

               (i)  Except as otherwise  specified herein, all references to the
                    terms "Revolving Loan" and "Revolving Loans" shall be deemed
                    to include Excess Revolving Loans;

               (ii) Except as otherwise  specified herein, all references to the
                    terms  "Note,"  "Notes,"  "Revolving  Note"  and  "Revolving
                    Notes"  shall be deemed to  include  the  Excess  Commitment
                    Notes;

               (iii)Except as otherwise  specified herein, all references to the
                    terms  "Commitment"  and  "Commitments"  shall be  deemed to
                    include the Excess Commitments; and

               (iii)Except as  otherwise  specified  herein,  references  to the
                    terms "Lender" and "Lenders"  shall be deemed to include the
                    Excess Commitment Lenders.

                    Notwithstanding  the foregoing,  no Excess Commitment Lender
               shall be  required  to make any  Revolving  Loan  (other  than an
               Excess  Revolving Loan) or fund or purchase  participations  with
               respect  to Letters  of Credit or Swing  Loans  except and to the
               extent  that  such  Excess   Commitment  Lender  has  provided  a
               Commitment  under the  Credit  Agreement  other  than its  Excess
               Commitment.  For all  purposes of the making of  Revolving  Loans
               other than Excess  Commitment  Loans, the terms  "Commitment" and
               "Commitments" shall exclude the Excess Commitments.

          (g)  Reductions of Excess Commitment. From and after the date on which
               any Additional Lender becomes a party to this Agreement  pursuant
               to Section 1.11 hereof,  the Excess  Commitments shall be reduced
               ratably as among the Excess Commitment Lenders in accordance with
               their  respective  Excess  Commitments,  dollar  for dollar by an
               amount equal to such Additional Lender's Commitment. In the event
               that any such  reduction of the Excess  Commitments  would reduce
               the  Excess  Commitments  below  the then  outstanding  principal
               amount of Excess  Revolving  Loans,  the Company shall prepay the
               Excess  Revolving  Loans to the  extent  necessary  to reduce the
               outstanding  principal  amount  of Excess  Revolving  Loans to an
               amount equal to the then  outstanding  Excess  Commitments  as so
               reduced.  On the date on which any such Additional Lender becomes
               party to the Credit Agreement, and in the event that at such time
               Excess  Revolving  Loans are  outstanding,  the Company  shall be
               deemed to have  irrevocably  requested a Borrowing  of  Revolving
               Loans under the Credit Agreement from the Lenders (including such
               Additional Lender but excluding the Excess Commitment  Lenders in
               their capacities as such) in an amount equal to the lesser of (i)
               the aggregate  principal  amount of Excess  Revolving  Loans then
               outstanding and (ii) such  Additional  Lender's  Commitment,  and
               each Lender (including such Additional Lender) hereby irrevocably
               agrees to fund to the Agent its ratable  share of such  Borrowing
               on such date, whether or not the conditions of Section 6.1 of the
               Agreement  have  been  satisfied.   The  proceeds  of  each  such
               Borrowing  shall  be used to  reduce  the  outstanding  principal
               amount of and accrued  interest on Excess  Revolving  Loans until
               paid in full. The  obligations of the Lenders  hereunder shall be
               absolute and  unconditional and shall not be affected or impaired
               by any Default or Event of Default  which may be occurring  under
               the Credit Agreement.

2.2. The Credit Agreement is hereby amended by adding thereto a new Section 1.11
     which reads as follows:

     Section 1.11.  Increase  in  Commitment.  Provided  no  Default or Event of
          Default  has  occurred  and is  continuing,  the  Company  may, on any
          Business Day on or prior to the Excess  Commitment  Termination  Date,
          with the  written  consent of the Agent  (which  consent  shall not be
          unreasonably   withheld),   increase  the  aggregate   amount  of  the
          Commitments  up to a maximum  amount of  $350,000,000  by delivering a
          Commitment  Amount Increase Request in the form of Exhibit F hereto at
          least five (5) Business  Days prior to the desired  effective  date of
          such  increase  (the  "Commitment  Amount  Increase")  identifying  an
          additional  Lender (or additional  Commitment agreed to be made by any
          existing  Lender) each such  additional  Lender or existing Lender (in
          its capacity as such) being referred to as an "Additional Lender") and
          the amount of its Commitment (or additional amount of its Commitment).
          The effective date of the Commitment  Amount  Increase shall be agreed
          upon by the Company,  such Lender and the Agent (whose  consent  shall
          not be unreasonably  withheld).  Upon the effectiveness  thereof, each
          new Lender (or, if applicable, each existing Lender which consented to
          an increase  in its  Commitment)  shall  advance  Revolving  Loans and
          purchase  Participating  Interests in all then outstanding  Letters of
          Credit in an amount  sufficient  such that after giving effect to such
          Revolving  Loans and purchases each Lender shall have  outstanding its
          pro rata share of  Revolving  Loans and  Participating  Interests.  It
          shall be a condition to such effectiveness that no Eurodollar Loans be
          outstanding  on the date of such  effectiveness  and that the  Company
          shall not have terminated any portion of the  Commitments  pursuant to
          Section 3.5(a) hereof.  The Company agrees to pay any fees or expenses
          of  the   Agent   relating   to  any   Commitment   Amount   Increase.
          Notwithstanding  anything herein to the contrary, no Lender shall have
          any obligation to increase its  Commitment and no Lender's  Commitment
          shall be increased without its consent thereto, and each Lender may at
          its option, unconditionally and without cause, decline to increase its
          Commitment.

2.3. Section 3.1 of the Credit  Agreement is hereby  amended in its entirety and
     as so amended shall be restated to read as follows:

     Section 3.1. Commitment Fee. (a) Commitments.  For the period from the date
          hereof to and including the Termination  Date, the Borrowers shall pay
          to the Agent for the  account of the  Lenders  (other  than the Excess
          Commitment  Lenders  in their  capacities  as  such) a  non-refundable
          commitment  fee at the rate per annum equal to the  Applicable  Margin
          (computed on the basis of a year of 360 days and actual days  elapsed)
          on the average daily Unused Commitments; provided however that for any
          calendar quarter during which the average daily outstanding balance of
          Revolving  Loans,  Swing Loans and L/C Obligations is less than 25% of
          the  aggregate  Commitments  the rate per annum set forth  above shall
          increase by 0.10%;  provided further,  that in no event shall the rate
          per annum payable  pursuant  hereto exceed 0.50%.  Such fee is due and
          payable  in  arrears  on  the  last  day  of  each  calendar   quarter
          (commencing with the first of such dates after the date hereof) and on
          the  Termination  Date;  and  provided  further  that for the purposes
          hereof, "Unused Commitments" shall be calculated without regard to the
          Excess Commitments.

          (b)  Excess  Commitments.  For the  period  from  June 2,  2003 to and
               including the Excess  Commitment  Termination  Date,  the Company
               shall pay to the Agent for the  account of the Excess  Commitment
               Lenders  a  non-refundable  commitment  fee at the rate per annum
               equal to the Applicable  Margin  (computed on the basis of a year
               of 360 days and actual days  elapsed) on the average daily Unused
               Excess Commitments. Such fee is due and payable in arrears on the
               last day of each calendar  quarter  (commencing with the first of
               such dates after the date  hereof)  and on the Excess  Commitment
               Termination Date

2.4. Section 3.4 of the Credit  Agreement is hereby  amended in its entirety and
     as so amended shall be restated to read as follows:

     Section 3.4. Voluntary Prepayments.  The Borrowers shall have the privilege
          of  prepaying  without  premium  or  penalty  (except  as set forth in
          Section 2.5 above) and in whole or in part (but, if in part, then: (i)
          in an amount not less than  $2,000,000,  or such lesser  amount as may
          then be outstanding, and (ii) in each case, in an amount such that the
          minimum amount required for a Borrowing pursuant to Section 1.5 hereof
          remains  outstanding)  any Borrowing of  Eurodollar  Loans at any time
          upon 3 Business  Days prior notice by the Borrower to the Agent or, in
          the case of a Borrowing of Domestic Rate Loans or Swing Loans,  notice
          delivered  by the  Borrower  to the  Agent no later  than  10:00  a.m.
          (Chicago time) on the date of prepayment,  such  prepayment to be made
          by the payment of the principal  amount to be prepaid and, in the case
          of any Eurodollar  Loans or Swing Loans,  accrued  interest thereon to
          the date fixed for  prepayment  plus any amounts due the Lenders under
          Section 2.5 hereof.  Notwithstanding  anything contained herein to the
          contrary,  from and  including  the  Section  2.4  Effective  Date (as
          defined in the First Amendment to this Agreement) to and including the
          Excess  Commitment  Termination  Date, all voluntary  prepayments made
          pursuant to this Section 3.4 shall be applied  first to the payment of
          outstanding  principal  of and accrued  interest  on Excess  Revolving
          Loans until payment in full thereof.

2.5. Section 3.5 of the Credit Agreement is hereby amended by (i)  redesignating
     subsection  (c) thereof as  subsection  (e) and (ii) by adding  thereto the
     following new subsections (c) and (d):

          (c)  If at any time during the period from and including the Amendment
               Effective  Date of the  First  Amendment  to this  Agreement  (as
               defined  in  the  First  Amendment  to  this  Agreement)  to  and
               including the Excess Commitment  Termination Date any Borrower or
               any Subsidiary  shall issue any  Indebtedness  for Borrowed Money
               permitted by Section 7.10(b)  hereof,  the Company shall promptly
               notify  the  Agent of the  estimated  Net Cash  Proceeds  of such
               issuance to be received by or for the account of such Borrower or
               such Subsidiary in respect thereof. Promptly upon receipt by such
               Borrower  or  such  Subsidiary  of  Net  Cash  Proceeds  of  such
               issuance,  the Company shall ratably prepay the Excess  Revolving
               Loans (and outstanding  Revolving Loans and L/C Obligations if an
               Event of Default  then  exists) in an  aggregate  amount equal to
               100%  of the  amount  of  such  Net  Cash  Proceeds.  The  Excess
               Commitments  (or all  Commitments  if an  Event of  Default  then
               exists) shall  immediately be ratably  reduced by an amount equal
               to the principal amount of any such Net Cash Proceeds.

          (d)  If at any time during the period from and including the Amendment
               Effective  Date  (as  defined  in the  First  Amendment  to  this
               Agreement)  of the  First  Amendment  to  this  Agreement  to and
               including the Excess Commitment  Termination Date any Borrower or
               any Subsidiary shall issue new equity securities  (whether common
               or preferred  stock or otherwise),  other than equity  securities
               issued in connection with the exercise of employee stock options,
               issued to the seller of an acquired business in connection with a
               Permitted Acquisition,  issued to a Borrower or any Subsidiary or
               issued as a  distribution  or  dividend to holders  thereof,  the
               Company shall promptly notify the Agent of the estimated Net Cash
               Proceeds of such issuance to be received by or for the account of
               such  Borrower or such  Subsidiary in respect  thereof.  Promptly
               upon  receipt by such  Borrower  or such  Subsidiary  of Net Cash
               Proceeds of such  issuance,  the Company shall ratably prepay the
               Excess Revolving Loans (and  outstanding  Revolving Loans and L/C
               Obligations if an Event of Default exists) in an aggregate amount
               equal to 100% of the amount of such Net Cash Proceeds. The Excess
               Commitments  (or all  Commitments  if an  Event of  Default  then
               exists) shall  immediately be ratably  reduced by an amount equal
               to the principal amount of any such Net Cash Proceeds.

2.6. Section 3.6 of the Credit  Agreement is hereby  amended in its entirety and
     as so amended shall be restated to read as follows:

     Section 3.6. Voluntary Terminations. The Borrowers shall have the privilege
     upon five Business  Days' prior notice from the Company  (which need not be
     joined in by any  Borrower) to the Agent (which shall  promptly  notify the
     Lenders)  to  ratably  terminate  the  Commitments  (including  the  Excess
     Commitments)  in whole or in part  (but if in part  then in the  amount  of
     $5,000,000  or  such  greater  amount  which  is an  integral  multiple  of
     $100,000);  provided that the  Commitments  may not be reduced to an amount
     less  than the sum of all  Revolving  Loans  and all L/C  Obligations  then
     outstanding unless there is deposited with the Agent as cash collateral for
     such Revolving  Loans and L/C  Obligations  cash in the amount by which the
     same exceed the amount of the Commitments. Any termination of the Revolving
     Commitments  below any Sublimit or the Swing Line  Sublimit  then in effect
     shall reduce such Sublimit or Swing Line Sublimit, as applicable, by a like
     amount.  The Agent  shall  give  prompt  notice to each  Lender of any such
     termination  of  the  Commitments.   Notwithstanding  the  foregoing,   any
     termination  of the  Commitments  hereunder  shall first ratably reduce the
     Excess  Commitments until the same are reduced or terminated in whole prior
     to any reduction of the  Commitments  (other than the Excess  Commitments).

2.7. Section 4.1 of the Credit Agreement is hereby amended by adding thereto the
     following sentence at the end thereof:

     In no event shall any  Collateral  of the U.K.  Borrowers  or the  Canadian
     Borrowers secure the Excess Revolving Loans.

2.8. The first sentence of Section 5.2 of the Credit Agreement is hereby amended
     in its entirety and as so amended shall be restated to read as follows:

               "Except as set forth in the Side Letter (as hereinafter defined),
          each Restricted Subsidiary is duly organized,  validly existing and in
          good standing (or their  equivalents under applicable local law) under
          the laws of the jurisdiction in which it is incorporated or organized,
          as the case may be, has full and  adequate  power to own its  Property
          and conduct its  business as now  conducted,  and is duly  licensed or
          qualified  and in good  standing  in each  jurisdiction  in which  the
          failure to be so qualified would have a Material Adverse Effect.

2.9. Section 5.5 of the Credit  Agreement  shall be amended by (i)  striking the
     reference  to  "December  31,  2001"  appearing  therein  and  substituting
     therefor  "December  31,  2002",  (ii)  striking the reference to "June 30,
     2002" appearing therein and substituting  therefor "March 31, 2003",  (iii)
     striking the reference to "the six (6) months then ended" appearing therein
     and substituting  therefor "the three (3) months then ended", (iv) striking
     the reference to "Arthur Andersen,  LLP" appearing therein and substituting
     therefor  "Ernst  & Young  LLP" and (v)  striking  the  reference  to "that
     certain Side Letter dated  September  26, 2002" and  substituting  therefor
     "that certain Side Letter dated June 2, 2003".

2.10.The following  definitions appearing in Section 9.1 of the Credit Agreement
     are hereby amended in their  respective  entireties and as so amended shall
     be restated to read as follows:

               "Borrowing"  shall mean, (i) with respect to Revolving  Loans and
          Swing  Loans,  the total of  Revolving  Loans or Swing Loans made to a
          given  Borrower  by all of the Lenders on a single  date,  in a single
          currency and having the same  maturity and (ii) with respect to Excess
          Revolving  Loans,  the total of  Excess  Revolving  Loans  made to the
          Company by all of the Excess  Commitment  Lenders on a single date and

                             EXCESS COMMITMENT NOTE

                                                         _________________, 2003

     For   value   received,   the   undersigned,    _____________________,    a
________________  corporation ("Borrower"),  hereby promises to pay to the order
of  ________________________   ______________________  (the  "Lender"),  at  the
principal office of Harris Trust and Savings Bank in Chicago,  Illinois,  in the
currency of each Excess  Revolving  Loan  evidenced  hereby in  accordance  with
Section 1 of the Credit Agreement, the aggregate unpaid principal amount of each
Excess Revolving Loan made by the Lender to the Borrower  pursuant to the Credit
Agreement  on the due date  therefore  as  specified  in the  Credit  Agreement,
together  with interest on the principal  amount of each Excess  Revolving  Loan
from time to time outstanding  hereunder at the rates, and payable in the manner
and on the dates specified in the Credit Agreement.

     The Lender shall  record on its books or records or on a schedule  attached
to this Note,  which is a part  hereof,  each Excess  Revolving  Loan made by it
pursuant to the Credit  Agreement,  any  repayment of principal and interest and
the principal balances from time to time outstanding hereon, and the currency in
which made,  provided  that prior to the  transfer of this Note all such amounts
shall be  recorded  on a schedule  attached  to this Note.  The record  thereof,
whether  shown on such books or records or on a schedule to this Note,  shall be
prima facie  evidence of the same,  provided,  however,  that the failure of the
Lender to record any of the  foregoing or any error in any such record shall not
limit or  otherwise  affect the  obligation  of the Borrower to repay all Excess
Revolving  Loans made to it  pursuant  to the  Credit  Agreement  together  with
accrued interest thereon.

     This Note is one of the Excess  Commitment  Notes referred to in the Credit
Agreement dated as of September 26, 2002, among the Borrowers,  Harris Trust and
Savings  Bank,  as Agent,  and the Lenders from time to time party  thereto,  as
amended  (the  "Credit  Agreement"),  and this Note and the  holder  hereof  are
entitled to all the  benefits  provided  for thereby or referred to therein,  to
which Credit  Agreement  reference is hereby made for a statement  thereof.  All
defined terms used in this Note,  except terms otherwise  defined herein,  shall
have the same meaning as in the Credit Agreement.

     This Note is issued by the Borrower  under the terms and  provisions of the
Credit Agreement and is secured by the Collateral  Documents,  and this Note and
the holder hereof are entitled to all of the benefits and security  provided for
thereby  or  referred  to  therein,  to which  reference  is  hereby  made for a
statement thereof.  This Note may be declared to be, or be and become, due prior
to its expressed maturity, voluntary prepayments may be made hereon, and certain
prepayments are required to be made hereon,  all in the events, on the terms and
with the effects provided in the Credit Agreement.

     This Note shall be  construed  in  accordance  with,  and  governed by, the
internal laws of the State of Illinois without regard to principles of conflicts
of law.

     The  Borrower  hereby  promises  to pay all costs and  expenses  (including
attorneys'  fees)  suffered or incurred by the holder hereof in collecting  this
Note or enforcing  any rights in any  collateral  herefor.  The Borrower  hereby
waives presentment for payment and demand.

     deemed to constitute one and the same  instrument.  This Amendment shall be
     construed in accordance with and governed by the internal laws of the state
     of Illinois.

4.3  Each  of the  Borrowers  hereby  agree  to pay  all  reasonable  costs  and

     with copies of the documents  which were required to be delivered under the

     of credit thereunder. The Additional Lender acknowledges and agrees that it
     has made and will continue to make, independently and without reliance upon
     the Agent or any other Lender and based on such  documents and  information
     as it has  deemed  appropriate,  its  own  credit  analysis  and  decisions
     relating  to  the  Credit   Agreement.   The   Additional   Lender  further
     acknowledges and agrees that the Agent has not made any  representations or
     warranties about the credit worthiness of the Company or any other party to
     the Credit Agreement or with respect to the legality, validity, sufficiency
     or  enforceability  of the Credit  Agreement  or the value of any  security
     therefore.






2.   Except as otherwise  provided in the Credit Agreement,  effective as of the
     date of acceptance  hereof by the Agent, the Additional Lender (i) shall be
     deemed  automatically  to have become a party to the Credit  Agreement  and
     have  all the  rights  and  obligations  of a  "Lender"  under  the  Credit
     Agreement as if it were an original signatory thereto and (ii) agrees to be
     bound by the terms and conditions  set forth in the Credit  Agreement as if
     it were an original signatory thereto.
