Item 1.01.   Entry into a Material Definitive Agreement.

     On October 14, 2005,  EMCOR Group,  Inc. (the  "Company"),  Comstock Canada
     Ltd., a  wholly-owned  subsidiary  of the Company  ("Comstock"),  and EMCOR
     Group (UK) plc., a  wholly-owned  subsidiary  of the Company  ("EMCOR UK"),
     entered  into  an  Amended  and  Restated  Credit  Agreement  (the  "Credit
     Agreement")  effective  October 17,  2005 with  Harris  N.A, as Agent,  The
     Governor and Company of Bank of Scotland,  Syndication  Agent,  and LaSalle
     Bank National Association, JPMorgan Chase Bank, N.A. and U.S. Bank National
     Association, as Co-Documentation Agents and certain other lenders listed on
     the  signature  pages thereof  (collectively,  the  "Lenders").  The Credit
     Agreement  amends and restates the Credit  Agreement  dated as of September
     26, 2002, as amended (the "Former  Credit  Agreement"),  among the Company,
     Comstock and EMCOR UK, Harris N.A., as Agent, and the lenders listed on the
     signature pages thereto. The Former Credit Agreement was filed as Exhibit 4
     to the Company's Form 8-K filed on October 4, 2002.

     The Credit  Agreement  establishes a revolving  credit facility under which
     the Company may borrow up to $350,000,000. Comstock and EMCOR UK may borrow
     a portion of the $350,000,000 directly from the Lenders, as provided in the
     Credit  Agreement.  If the Company so desires it may  identify  one or more
     additional   lenders  (which  may  include  existing  Lenders)  willing  to
     participate, or increase their participation,  in the Credit Agreement, and
     thereby  increase  the  Company's  maximum   borrowings  under  the  Credit
     Agreement  by  up  to  an  additional  $150,000,000,   provided  that  such
     additional lender is acceptable,  in their respective  reasonable judgment,
     to Harris N.A.  and each Lender which has  outstanding,  at the time of the
     increased  commitment,  a letter of credit  issued  by it  pursuant  to the
     Credit Agreement.

     The Credit Agreement  contains  financial  covenants,  representations  and
     warranties  and  events  of  default  and has a  5-year  term.  The  Credit
     Agreement is secured by substantially  all of the assets of the Company and
     substantially  all of the assets of  substantially  all of its subsidiaries
     pursuant  to a Security  Agreement  and  Pledge  Agreement.  The  Company's
     obligations  under the Credit Agreement are guaranteed by substantially all
     of its subsidiaries pursuant to a Guaranty.

     The Credit Agreement is attached hereto as Exhibit 4.1.

     The foregoing  description  of the Credit  Agreement does not purport to be
     complete  and is qualified in its entirety by reference to the full text of
     the Credit Agreement, attached hereto as Exhibit 4.1.

Item 1.02.   Termination of a Material Definitive Agreement.

     As described above in Item 1.01, the Former Credit Agreement is amended and
     restated in its entirety by the Credit Agreement.

Harris N.A. (successor by merger to Harris Trust and Savings Bank), individually
and as Agent Chicago, Illinois

and the other Lenders from time to time party hereto

Ladies and Gentlemen:

     The undersigned,  EMCOR Group Inc., a Delaware corporation (the "Company"),
Comstock  Canada Ltd., a Canadian  corporation  ("Comstock  Canada"),  and EMCOR
Group (UK) plc., a United Kingdom public limited company ("EMCOR UK"),  refer to
the Credit Agreement dated as of September 26, 2002, as amended and currently in
effect  among  the  Company,  Comstock  Canada,  EMCOR UK and you  (such  Credit
Agreement  as amended is referred to as the  "Existing  Agreement")  pursuant to
which you agreed to make a revolving credit (the "Revolving  Credit")  available
to the  Borrowers,  all as more fully set forth therein.  The Company,  Comstock
Canada and EMCOR UK request you to amend the Existing  Agreement to, among other
things,  extend the Termination Date, to make certain further  amendments to the
Existing Agreement and, for the sake of convenience and clarity,  to restate the
Existing  Agreement  in its  entirety  as so  amended.  Accordingly,  upon  your
acceptance  hereof  in the  space  provided  for  that  purpose  below  and upon
satisfaction of the conditions precedent to effectiveness hereinafter set forth,
the Existing  Agreement and all of the Exhibits  thereto shall be amended and as
so amended shall be restated in their entirety to read as follows:

SECTION 1. THE REVOLVING CREDIT.

     Section 1.1.  Revolving Credit.  Subject to all of the terms and conditions
hereof,  each Lender,  by its acceptance  hereof,  severally  agrees to extend a
Revolving  Credit to the Borrowers in the amount of its commitment to extend the
Revolving  Credit set forth  opposite  its name on Schedule 1.1 hereto or on the
Assignment  Agreement to which it is a party (its  "Commitment" and cumulatively
for all the  Lenders,  the  "Commitments")  (subject to any  reductions  thereof
pursuant to the terms  hereof)  prior to the  Termination  Date.  Subject to the
terms and conditions  hereof,  such  Revolving  Credit may be availed of by each
Borrower in its discretion  from time to time, be repaid and used again,  during
the period from the date  hereof to and  including  the  Termination  Date.  The
Revolving  Credit,  subject to all of the terms and  conditions  hereof,  may be
utilized by any one or more of the Borrowers in the form of Revolving  Loans and
Letters of Credit, all as more fully hereinafter set forth;  provided,  however,
that  the  aggregate  amount  of  the  Revolving  Loans,  Swing  Loans  and  L/C
Obligations outstanding at any one time of all the Borrowers when taken together
with the  amount of  outstanding  borrowings  and  letters  of credit  under the
Canadian  Facility,  if any,  shall  not at any  time  exceed  the  Commitments,
provided,  further,  that in  addition  to,  and not in  substitution  for,  the
foregoing  requirement:  (i) the aggregate outstanding amount of L/C Obligations
shall in no event  exceed  $125,000,000  at any one time  outstanding,  (ii) the
aggregate  amount of  Revolving  Loans  made to the U.K.  Borrowers  when  taken
together with the aggregate amount of L/C Obligations with respect to Letters of
Credit  issued  for the  account  of the U.K.  Borrowers  and  their  respective
Subsidiaries  shall in no event exceed  $50,000,000 at any one time outstanding,
and (iii) the aggregate amount of Revolving Loans made to the Canadian Borrowers
and of L/C Obligations  with respect to Letters of Credit issued for the account
of the Canadian Borrowers and their respective  Subsidiaries when taken together
with the aggregate outstanding amount of loans made under the Canadian Facility,
if any,  and  letters  of  credit  issued  thereunder  shall in no event  exceed
$50,000,000 at any one time  outstanding (the  "Sublimits").  The obligations of
the Lenders  hereunder  are several and not joint and no Lender  shall under any
circumstances  be  obligated  to  extend  credit  hereunder  in  excess  of  its
Commitment.

     For all  purposes of this  Agreement,  where a  determination  of the used,
unused or available  amount of the Commitments or of the  outstanding  amount of
Credit Utilizations is necessary,  Credit Utilizations payable in an Alternative
Currency shall be converted into their U.S. Dollar Equivalent.  Such conversions
shall be made on the date of each Credit Utilization in an Alternative  Currency
as to that Credit  Utilization  and all Credit  Utilizations  shall be converted
into their  U.S.  Dollar  Equivalent  as of the last day of each month or at the
time of each Credit  Utilization should the Agent so elect. If the last day of a
month  is not a  Business  Day,  such  conversion  shall  be made as of the next
Business Day. The Agent shall promptly notify the Company of such  determination
of a U.S. Dollar Equivalent and of the basis therefor.  All Credit  Utilizations
and  interest  thereon  shall be  repaid  in the  currency  in which  they  were
effected.

     Section 1.2.  Revolving  Loans.  Subject to all of the terms and conditions
hereof,   the  Revolving  Credit  may  be  availed  of  in  the  form  of  loans
(individually a "Revolving Loan" and collectively the "Revolving  Loans").  Each
Borrowing of Revolving  Loans shall,  except to the extent  otherwise  agreed in
writing by all Lenders,  be made ratably by the Lenders in accordance with their
Percentages.  Each  Borrowing of Revolving  Loans shall be in the minimum amount
specified  in Section  1.5  hereof.  All  Revolving  Loans made by a Lender to a
particular Borrower shall be evidenced by a single Revolving Credit Note of such
Borrower (individually a "Revolving Credit Note" and collectively the "Revolving
Credit Notes") payable to the order of such Lender,  each Revolving  Credit Note
to be in the form (with  appropriate  insertions)  attached hereto as Exhibit A.
Without regard to the face principal  amount of each Lender's  Revolving  Credit
Note,  the actual  principal  amount at any time  outstanding  and owing by each
Borrower on account of Revolving  Loans shall be the sum of all Revolving  Loans
then or  theretofore  made  thereon  by such  Lender to such  Borrower  less all
payments actually received thereon.

     Section 1.3. Letters of Credit.

          (a) General Terms.  Subject to the terms,  conditions and  limitations
     hereof  (including  those set forth in Section 1.1 hereof),  as part of the
     Revolving  Credit,  the Applicable  Issuer shall issue Financial Letters of
     Credit or Performance Letters of Credit (each a "Letter of Credit") for the
     account of any one or more of the Borrowers in, as requested by the Company
     acting on behalf of the applicable Borrower, U.S. Dollars or an Alternative
     Currency.  Notwithstanding anything contained herein to the contrary, those
     certain  letters of credit issued at the Company's  request for the account
     of the  applicable  Borrowers  by Harris  N.A.  or by any other  Applicable
     Issuer and listed on Schedule 1.3 hereof (the "Existing Letters of Credit")
     shall each  constitute a "Letter of Credit" herein for all purposes of this
     Agreement,  to the same extent,  and with the same force and effect,  as if
     such Existing Letters of Credit had been issued under this Agreement at the
     request of the Company on behalf of the applicable  Borrowers.  Each Letter
     of Credit shall be issued by the Applicable  Issuer,  but each Lender shall
     be obligated to reimburse the  Applicable  Issuer for its Percentage of the
     amount of each drawing thereunder and, accordingly, the undrawn face amount
     of each Letter of Credit shall  constitute  usage of the Commitment of each
     Lender pro rata in accordance with each Lender's Percentage. Each Letter of
     Credit shall  conform to the  Applicable  Issuer's  policies as to form and
     shall be a Letter of Credit which the Applicable Issuer may lawfully issue.
     Each  Letter  of Credit  shall  support  payment  of an  obligation  of the
     Borrower  who applies for same or an  obligation  of a  Subsidiary  of same
     which is a Restricted  Subsidiary or of a Person  described in  subsections
     (j),  (n) or (o) of  Section  7.12 in  which  the  applicant  or one of its
     Restricted Subsidiaries has an equity interest.

          (b)  Applications.  At any  time  before  the  Termination  Date,  the
     Applicable Issuer shall, subject to all of the terms and conditions hereof,
     at the request of the Company  (which is acting on behalf of the  Borrowers
     pursuant to Section 1.7 hereof),  issue one or more Letters of Credit, in a
     form satisfactory to the Applicable  Issuer, in an aggregate face amount as
     set forth above, upon the receipt of an application for the relevant Letter
     of Credit in the form customarily  prescribed by the Applicable  Issuer for
     the type of Letter of Credit in question, duly executed by the Borrower for
     whose  account  such Letter of Credit was issued  (each an  "Application").
     Notwithstanding anything contained herein to the contrary, the applications
     executed by the  Borrowers  with respect to the Existing  Letters of Credit
     shall each constitute an "Application" herein. Each Letter of Credit issued
     hereunder  shall (a) be payable,  as  determined  by the Company  acting on
     behalf  of the  applicable  Borrower,  in U.S.  Dollars  or an  Alternative
     Currency and (b) expire not later than (i) the Termination Date for Letters
     of Credit  issued by Harris N.A. and (ii) the date which is five days prior
     to the  Termination  Date for  Letters  of Credit  issued by an  Applicable
     Issuer  other than Harris N.A.  Notwithstanding  anything  contained in any
     Application to the contrary,  (i) the applicable  Borrower's  obligation to
     pay fees in connection  with each Letter of Credit shall be as  exclusively
     set forth in Section  3.3  hereof,  (ii)  except as  otherwise  provided in
     Section  3.5 hereof,  prior to the  existence  of an Event of Default,  the
     Applicable  Issuer  will not call for the  funding by the  Borrower  of any
     amount under a Letter of Credit,  or any other form of collateral  security
     (other  than  the  Collateral  and  the   Guarantees)  for  the  Borrower's
     obligations  in  connection  with  such  Letter  of  Credit,  before  being
     presented with a drawing thereunder,  and (iii) if the Applicable Issuer is
     not  timely  reimbursed  for the  amount of any  drawing  under a Letter of
     Credit on the date such  drawing  is paid,  the  Borrower's  obligation  to
     reimburse the  Applicable  Issuer for the amount of such drawing shall bear
     interest  (which the  relevant  Borrower  hereby  promises to pay) from and
     after the date such drawing is paid at a rate per annum equal to the sum of
     2% plus the  Applicable  Margin for  Eurodollar  Loans from time to time in
     effect.  The Issuer will  promptly  notify the Agent of each  request for a
     Letter of Credit  and of the  issuance  of a Letter of Credit and the Agent
     shall  promptly  thereafter  so notify  each of the  Lenders.  If an Issuer
     issues any Letters of Credit with expiration  dates that are  automatically
     extended  unless such Issuer gives notice that the expiration date will not
     so extend beyond its then scheduled  expiration date, such Issuer will give
     such  notice of  non-renewal  before the time  necessary  to  prevent  such
     automatic  extension if before such required notice date (i) the expiration
     date of such Letter of Credit if so extended would be after the Termination
     Date,  (ii) the  Commitments  have  been  terminated,  or (iii) an Event of
     Default exists and the Required Lenders have given the Issuer  instructions
     not to so permit the  extension  of the  expiration  date of such Letter of
     Credit.  Without  limiting the  generality  of the  foregoing,  the parties
     hereto  hereby  confirm and agree that each  Issuer's  obligation to issue,
     amend or extend the expiration date of a Letter of Credit is subject to the
     conditions  of Section 6, the other terms of this Section 1.3 and the other
     provisions  of this  Agreement  and such  Issuer  will not issue,  amend or
     extend the expiration  date of any Letter of Credit if any Lender  notifies
     such  Issuer of any  Default or Event of  Default  that is  continuing  and
     directs the Issuer not to take such action.

          (c) The  Reimbursement  Obligation.  Subject to Section 1.3(b) hereof,
     the  obligation  of a Borrower to reimburse the  Applicable  Issuer for all
     drawings  under a Letter of Credit  issued for such  Borrower's  account (a
     "Reimbursement Obligation") shall be governed by the Application related to
     such Letter of Credit,  except that  reimbursement of each drawing shall be
     made in immediately available funds at the designated office of such Issuer
     by no later  than  12:00  Noon  (local  time at the  issuing  office of the
     Issuer) on the date when such  drawing is paid.  If the  relevant  Borrower
     does  not  make  any  such  reimbursement  payment  on the date due and the
     Participating  Lenders (as hereinafter  defined) fund their  participations
     therein in the manner set forth in Section 1.3(d) below,  then all payments
     thereafter  received by the  Applicable  Issuer in  discharge of any of the
     relevant Reimbursement  Obligations shall be distributed in accordance with
     Section 1.3(d) below.

          (d)  The  Participating  Interests.  Each  Lender,  by its  acceptance
     hereof,  severally agrees to purchase from the Applicable  Issuer,  and the
     Applicable   Issuer   hereby   agrees  to  sell  to  each  such  Lender  (a
     "Participating  Lender"), an undivided percentage participating interest (a
     "Participating  Interest"), to the extent of its Percentage, in each Letter
     of  Credit  issued  by,  and each  Reimbursement  Obligation  owed to,  the
     Applicable Issuer.  Upon any failure by a Borrower to pay any Reimbursement
     Obligation  in  respect of a Letter of Credit  issued  for such  Borrower's
     account at the time  required on the date the related  drawing is paid,  as
     set forth in Section 1.3(c) above, or if the Applicable  Issuer is required
     at any time to return to a Borrower or to a trustee, receiver,  liquidator,
     custodian or other  Person any portion of any payment of any  Reimbursement
     Obligation,  each  Participating  Lender shall, not later than the Business
     Day it receives a certificate from the Applicable Issuer to such effect, if
     such  certificate is received before 1:00 p.m. (local time at the office of
     the  Issuer),  or not  later  than  the  following  Business  Day,  if such
     certificate is received  after such time,  pay to the Applicable  Issuer an
     amount equal to its  Percentage of such unpaid or recaptured  Reimbursement
     Obligation  together with interest on such amount accrued from the date the
     related  payment  was  made by the  Applicable  Issuer  to the date of such
     payment by such Participating  Lender at a rate per annum equal to (i) from
     the date the related payment was made by the Applicable  Issuer to the date
     two (2) Business  Days after  payment by such  Participating  Lender is due
     hereunder,  the Federal Funds Rate for each such day and (ii) from the date
     two (2)  Business  Days  after  the date  such  payment  is due  from  such
     Participating Lender to the date such payment is made by such Participating
     Lender,  the rate per annum  determined by adding the Applicable  Margin to
     the  Domestic  Rate in effect  for each such day.  Each such  Participating
     Lender  shall  thereafter  be entitled to receive  its  Percentage  of each
     payment received in respect of the relevant Reimbursement Obligation and of
     interest paid thereon,  with the Applicable Issuer retaining its Percentage
     as a Lender hereunder.

          The several  obligations of the  Participating  Lenders to the Issuers
     under this Section 1.3 shall be  absolute,  irrevocable  and  unconditional
     under any and all  circumstances  whatsoever  (except,  to the extent  such
     Borrower is relieved from its obligation to reimburse the Applicable Issuer
     for a  drawing  under a Letter  of  Credit  due  solely  to the  Applicable
     Issuer's  gross  negligence  or  willful  misconduct  in  determining  that
     documents received under the Letter of Credit comply with the terms thereof
     as determined by a final,  non-appealable  judgment of a court of competent
     jurisdiction)  and shall not be subject  to any  set-off,  counterclaim  or
     defense  to  payment  which any  Participating  Lender may have or have had
     against any one or more of the  Borrowers,  the Agent,  any other Lender or
     any  other  Person  whatsoever.  Without  limiting  the  generality  of the
     foregoing,  such obligations  shall not be affected by any Default or Event
     of Default or by any  reduction or  termination  of any  Commitment  of any
     Lender,  and each payment by a Participating  Lender under this Section 1.3
     shall be made  without  any offset,  abatement,  withholding  or  reduction
     whatsoever.  The Agent shall be entitled to offset amounts received for the
     account of a Lender under this  Agreement  against  unpaid amounts due from
     such Lender hereunder (whether as fundings of  participations,  indemnities
     or otherwise).

          (e) Indemnification.  Each of the Participating  Lenders shall, to the
     extent of their  respective  Percentages,  indemnify  the  Issuers  (to the
     extent  not  reimbursed  by  the  Borrowers)   against  any  cost,  expense
     (including  reasonable  counsel  fees and  disbursements),  claim,  demand,
     action, loss or liability (except such as result solely from the applicable
     Issuer's gross  negligence or willful  misconduct as determined by a final,
     non-appealable  judgment  of a court of  competent  jurisdiction)  that the
     Issuers may suffer or incur in  connection  with any Letter of Credit.  The
     obligations of the Participating  Lenders under this Section 1.3(e) and all
     other parts of this Section 1.3 shall survive termination of this Agreement
     and of all other L/C Documents.

     Section 1.4. Manner of Borrowing Revolving Loans.

          (a) Generally. The Company (which is acting on behalf of the Borrowers
     pursuant to Section 1.7 hereof) 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 Revolving Loans, in each case specifying the Borrower to
     which the proceeds of such  Borrowing  are to be  disbursed,  the amount of
     each such  Borrowing,  the currency of such  Borrowing  (which must be U.S.
     Dollars or an Alternative  Currency,  except that Domestic Rate Loans shall
     only be available in U.S. Dollars),  the date such Borrowing is to be made,
     which shall be not less than three Business Days following the date of such
     notice in the case of a Borrowing in an Alternative Currency or a Borrowing
     of  Eurodollar  Loans,  but  which  may be the  same  day in the  case of a
     Borrowing  of  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 Lender of its receipt of each such
     notice.  Not later than 1:00 p.m. on the date  specified for any Borrowing,
     each Lender shall make the proceeds of its Revolving Loan  comprising  part
     of such Borrowing available in immediately  available funds to the Agent in
     Chicago  except  (i) in the  case  of  Revolving  Loans  denominated  in an
     Alternative  Currency,  which shall be made available at such office as the
     Agent has  previously  specified  in a notice to each  Lender in such funds
     which are then customary for the settlement of  international  transactions
     in such currency and no later than such local time as is necessary for such
     funds to be received and transferred to the relevant  Borrower for same day
     value on the date of the  relevant  Borrowing  and (ii) to the extent  such
     Borrowing is a reborrowing, in whole or in part, of the principal amount of
     a maturing Borrowing of Loans to the same Borrower and in the same currency
     (a  "Refunding  Borrowing"),  in which  case each  Bank  shall  record  the
     Revolving  Loan  made by it as a part of such  Refunding  Borrowing  on its
     books or records or on a schedule to the Note held by it, and shall  effect
     the  repayment,  in whole  or in  part,  as  appropriate,  of its  maturing
     Revolving Loan through the proceeds of such new Revolving Loan.  Subject to
     all of the terms and  conditions  hereof,  the  proceeds  of each  Lender's
     Revolving Loan  denominated in U.S.  Dollars shall be made available to the
     relevant  Borrower  on the date  requested  at the  office  of the Agent in
     Chicago and the proceeds of each Lender's Revolving Loans denominated in an
     Alternative  Currency at such office as the Agent has previously  agreed to
     with the relevant  Borrower,  in each case in the type of funds received by
     the Agent from the Lenders.  The  Lenders'  obligations  to make  Revolving
     Loans in an Alternative Currency or to provide or participate in Letters of
     Credit payable in an  Alternative  Currency shall always be subject to such
     Alternative Currency being freely available to each of them in the relevant
     market. If any Lender reasonably determines that such currency requested is
     unavailable  to it in the  amount  and for the term  requested  it shall so
     notify the Agent  within two hours of its receipt of the  aforesaid  notice
     and the Agent shall  promptly  notify the Company and each other  Lender of
     its receipt of such notice and the request of the Company for the Borrowing
     in  the  Alternative   Currency  in  question  shall  otherwise  be  deemed
     withdrawn. Borrowing notices shall otherwise be irrevocable.

          (b) Agent  Reliance on Bank Funding.  Unless the Agent shall have been
     notified by a Lender  before the time when such Lender is scheduled to make
     payment to the Agent of the  proceeds of a Revolving  Loan that such Lender
     does not intend to make such payment, the Agent may assume that such Lender
     has made such  payment  when due and the Agent  may in  reliance  upon such
     assumption  (but shall not be required  to) make  available to the relevant
     Borrower the proceeds of the Revolving  Loan to be made by such Lender and,
     if any Lender has not in fact made such  payment to the Agent,  such Lender
     shall,  on  demand,  pay to the Agent the  amount  made  available  to such
     Borrower  attributable  to such Lender  together with  interest  thereon in
     respect of each day during the period  commencing  on the date such  amount
     was made available to such Borrower and ending on (but  excluding) the date
     such  Lender pays such amount to the Agent at a rate per annum equal to the
     Federal Funds Rate or, in the case of a Revolving  Loan  denominated  in an
     Alternative  Currency,  the cost to the  Agent of  funding  the  amount  it
     advanced to fund such Lender's  Revolving Loan, as determined by the Agent.
     If such amount is not  received  from such Lender by the Agent  immediately
     upon demand,  the applicable  Borrower will, on demand,  repay to the Agent
     the  proceeds  of the  Revolving  Loan  attributable  to such  Lender  with
     interest  thereon at a rate per annum equal to the interest rate applicable
     to the relevant Revolving Loan.

     Section 1.5.  Minimum  Borrowing  Amounts.  Each Borrowing of Domestic Rate
Loans shall be in an amount not less than  $2,000,000,  or such  greater  amount
which is an integral  multiple of $100,000,  and each  Borrowing  of  Eurodollar
Loans shall be in an amount not less than  $5,000,000,  or such  greater  amount
which is an integral multiple of $100,000.

     Section 1.6.  Maturity of Loans.  Each Eurodollar Loan and Swing Loan shall
mature  and  become  due and  payable  on the  last day of the  Interest  Period
applicable  thereto,  provided that, subject to the terms and conditions of this
Agreement, a Eurodollar Loan may be refunded through a Refunding Borrowing. Each
Domestic  Rate Loan shall  mature and become due and payable on the  Termination
Date.

     Section 1.7.  Appointment  of Company as Agent for  Borrowers;  Reliance by
Agent.

          (a) Appointment. Each Borrower irrevocably appoints the Company as its
     agent hereunder to make requests on such Borrower's  behalf under Section 1
     hereof for Borrowings to be made by such Borrower and for Letters of Credit
     to be issued  for such  Borrower's  account  and to take any  other  action
     contemplated  by  the  Loan  Documents  with  respect  to  credit  extended
     hereunder to such Borrower.  The Agent and the Lenders shall be entitled to
     conclusively  presume  that  any  action  by the  Company  under  the  Loan
     Documents is taken on behalf of any one or more of the Borrowers whether or
     not the Company so indicates.

          (b) Reliance.  All requests for  Borrowings  and selection of interest
     rates,  currencies  and Interest  Periods to be  applicable  thereto may be
     written or oral,  including by telephone or telecopy.  The Borrowers  agree
     that the Agent may rely on any such notice given by any person the Agent in
     good faith believes is an Authorized  Representative  without the necessity
     of independent  investigation (the Borrowers hereby  indemnifying the Agent
     and Lenders from any liability or loss ensuing from such reliance),  and in
     the event any such  telephonic  or other  oral  notice  conflicts  with any
     written  confirmation,  such oral or telephonic  notice shall govern if the
     Agent has acted in reliance thereon.

     Section 1.8. Swing Loans.

          (a) Generally.  Subject to the terms and conditions hereof, as part of
     the Revolving  Credit,  the Agent agrees to make loans to the Company under
     the Swing Line  (individually  a "Swing Loan" and  collectively  the "Swing
     Loans") which shall not in the aggregate at any time outstanding exceed the
     Swing Line  Sublimit.  The Swing Loans may be availed of the  Company  from
     time to time and Borrowings  thereunder may be repaid and used again during
     the period ending on the  Termination  Date;  provided that each Swing Loan
     must be repaid on the last day of the Interest Period  applicable  thereto.
     Each Swing Loan shall be in a minimum  amount of $250,000  or such  greater
     amount which is an integral multiple of $100,000.

          (b) Swing Note. The Swing Loans made to the Company by the Agent shall
     be evidenced by a single promissory note of the Company issued to the Agent
     in the form of Exhibit  A-2  hereto.  Such  promissory  note is referred to
     herein as the "Swing Note".

          (c) Interest on Swing Loans. Each Swing Loan shall bear interest until
     maturity  (whether by  acceleration or otherwise) at a rate per annum equal
     to (i) the sum of the Domestic Rate plus the Applicable Margin for Domestic
     Rate  Loans  under  the  Revolving  Credit  as from  time to time in effect
     (computed  on the basis of a year of 365 or 366  days,  as the case may be,
     for the actual number of days elapsed) or (ii) the Agent's  Quoted Rate (as
     hereinafter  defined)  (computed on the basis of a year of 360 days for the
     actual  number of days  elapsed).  Interest on each Swing Loan shall be due
     and payable prior to such maturity on the last day of each Interest  Period
     applicable thereto.

          (d) Requests for Swing Loans.  The Company  shall give the Agent prior
     notice  (which may be  written  or oral) no later than 12:00 Noon  (Chicago
     time) on the date upon which the  Company  requests  that any Swing Loan be
     made of the amount and date of such Swing  Loan,  and the  Interest  Period
     requested  therefor.  Within 30 minutes after  receiving  such notice,  the
     Agent  shall in its  discretion  quote an  interest  rate to the Company at
     which the Agent would be willing to make such Swing Loan  available  to the
     Company  for the  Interest  Period so  requested  (the rate so quoted for a
     given Interest  Period being herein  referred to as "Agent's Quoted Rate").
     The Company  acknowledges  and agrees that the interest rate quote is given
     for  immediate  and  irrevocable  acceptance.  If the  Company  does not so
     immediately accept the Agent's Quoted Rate for the full amount requested by
     the Company for such Swing  Loan,  the Agent's  Quoted Rate shall be deemed
     immediately  withdrawn  and such Swing Loan shall bear interest at the rate
     per annum  determined  by adding the  Applicable  Margin for Domestic  Rate
     Loans under the Revolving  Credit to the Domestic Rate as from time to time
     in effect. Subject to the terms and conditions hereof, the proceeds of such
     Swing Loan shall be made  available to the Company on the date so requested
     at the offices of the Agent in Chicago, Illinois. Anything contained in the
     foregoing to the contrary notwithstanding,  (i) the obligation of the Agent
     to make Swing Loans shall be subject to all of the terms and  conditions of
     this  Agreement and (ii) the Agent shall not be obligated to make more than
     one Swing Loan during any one day.

          (e) Refunding  Loans. In its sole and absolute  discretion,  the Agent
     may at any  time,  on  behalf  of the  Company  (which  hereby  irrevocably
     authorizes the Agent to act on its behalf for such purpose) and with notice
     to the Company, request each Lender to make a Revolving Loan in the form of
     a Domestic Rate Loan in an amount equal to such Lender's  Percentage of the
     amount of the Swing  Loans  outstanding  on the date such  notice is given.
     Unless an Event of Default  described  in Section  8.1(k) or 8.1(l)  exists
     with respect to the Company, regardless of the existence of any other Event
     of Default,  each Lender shall make the proceeds of its requested Revolving
     Loan available to the Agent, in immediately available funds, at the Agent's
     principal office in Chicago,  Illinois, before 12:00 Noon (Chicago time) on
     the Business Day  following  the day such notice is given.  The proceeds of
     such Borrowing of Revolving Loans shall be immediately applied to repay the
     outstanding Swing Loans.

          (f) Participations. If any Lender refuses or otherwise fails to make a
     Revolving Loan when requested by the Agent pursuant to Section 1.8(e) above
     (due to the existence of an Event of Default described in Section 8.1(k) or
     8.1(l) exists with respect to the Company or otherwise),  such Lender will,
     by the time and in the manner such  Revolving  Loan was to have been funded
     to the Agent, purchase from the Agent an undivided  participating  interest
     in the outstanding  Swing Loans in an amount equal to its Percentage of the
     aggregate  principal  amount of Swing  Loans that were to have been  repaid
     with such Revolving Loans. Each Lender that so purchases a participation in
     a Swing Loan shall thereafter be entitled to receive its Percentage of each
     payment of  principal  received on the Swing Loan and of interest  received
     thereon  accruing  from  the date  such  Lender  funded  to the  Agent  its
     participation  in such Loan.  The several  obligations of the Lenders under
     this Section shall be absolute,  irrevocable,  and unconditional  under any
     and all  circumstances  whatsoever and shall not be subject to any set-off,
     counterclaim  or defense  to payment  which any Lender may have or have had
     against the Company, any other Borrower, any Guarantor, any other Lender or
     any  other  Person  whatever.   Without  limiting  the  generality  of  the
     foregoing,  such obligations  shall not be affected by any Default or Event
     of Default or by any reduction or  termination  of the  Commitments  of any
     Lender,  and each payment made by a Lender under this Section shall be made
     without any offset, abatement, withholding or reduction whatsoever.

     Section  1.9.  Default  Rate.  Notwithstanding  anything  to  the  contrary
contained herein,  while any Event of Default exists or after acceleration,  the
relevant  Borrower shall pay interest (after as well as before entry of judgment
thereon to the extent  permitted  by law) on the  principal  amount of all Loans
owing by it at a rate per annum equal to:

          (a) for any  Domestic  Rate Loan or any Swing  Loan  bearing  interest
     based on the Domestic Rate, the sum of 2.0% plus the Applicable Margin plus
     the Domestic Rate from time to time in effect;

          (b) for any Eurodollar Loan  denominated in U.S.  Dollars or any Swing
     Loan bearing  interest at the Agent's Quoted Rate, the sum of 2.0% plus the
     rate of  interest  in effect  thereon  at the time of such Event of Default
     until the end of the Interest Period applicable thereto and, thereafter, at
     a rate per annum  equal to the sum of 2.0% plus the  Applicable  Margin for
     Domestic Rate Loans plus the Domestic Rate from time to time in effect; and

          (c) for any Eurodollar  Loan  denominated in an Alternative  Currency,
     the sum of 2.0% plus the rate of interest in effect  thereon at the time of
     such  Event of  Default  until the end of the  Interest  Period  applicable
     thereto  and,  thereafter  at a rate  per  annum  equal  to the  sum of the
     Applicable  Margin,  plus a rate of two  percent  (2.0%)  plus  the rate of
     interest  per  annum  as  determined  by the  Agent  (rounded  upwards,  if
     necessary,  to the nearest whole multiple of  one-sixteenth  of one percent
     (1/16%)) at which overnight or weekend deposits of the appropriate currency
     (or, if such amount due remains unpaid more than three Business Days,  then
     for such other  period of time not longer  than six months as the Agent may
     elect in its absolute discretion) for delivery in immediately available and
     freely  transferable  funds would be offered by the Agent to major banks in
     the  interbank  market upon request of such major banks for the  applicable
     period  as  determined  above  and in an amount  comparable  to the  unpaid
     principal amount of any such Loan (or, if the Agent is not placing deposits
     in such currency in the interbank market, then the Agent's cost of funds in
     such currency for such period).

provided, however, that in the absence of acceleration, any adjustments pursuant
to this  Section  shall be made at the  election  of the  Agent,  acting  at the
request or with the consent of the Required Lenders,  with written notice to the
Borrowers.  While any Event of Default  exists or after  acceleration,  interest
shall be paid on demand of the Agent at the  request or with the  consent of the
Required Lenders.

     Section  1.10.  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  Termination  Date,  from time to time,  increase the  aggregate
amount of the Commitments up to a maximum amount of $500,000,000 by delivering a
Commitment Amount Increase Request in the form of Exhibit E hereto at least five
(5) Business  Days prior to the desired  effective  date of such  increase  (the
"Commitment Amount Increase") identifying an additional Lender acceptable to the
Agent and each Applicable  Issuer in their  reasonable  discretion 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  Additional  Lender  and the  Agent  (whose
agreement shall not be unreasonably withheld or delayed). Upon the effectiveness
thereof,  each  Additional  Lender 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  (including  such  Additional  Lender)  shall have  outstanding  its
respective  Percentage  of  the  aggregate  Revolving  Loans  and  Participating
Interests then outstanding.  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 reasonable fees or expenses
of the Agent (including  reasonable fees and  disbursements of counsel) 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.

SECTION 2. INTEREST.

     Section  2.1.  Domestic  Rate  Loans.  Each  Domestic  Rate Loan shall bear
interest  (which the relevant  Borrower  promises to pay in arrears at the times
herein  provided)  at the rate per annum  determined  by adding  the  Applicable
Margin to the Domestic  Rate as in effect from time to time,  provided that if a
Domestic Rate Loan is not paid when due (whether by lapse of time,  acceleration
or  otherwise),  such  Revolving  Loan shall bear  interest  (which the relevant
Borrower promises to pay at the times hereinafter  provided),  whether before or
after  judgment,  and  until  payment  in full  thereof,  at the rate per  annum
specified in Section 1.9 hereof.  Interest on the  Domestic  Rate Loans shall be
payable in  arrears on the last day of each  calendar  month  (beginning  on the
first of such dates after the date  hereof)  and at  maturity  of the  Revolving
Credit Notes and interest after maturity shall be due and payable upon demand.

     Section 2.2.  Eurodollar  Loans.  Each  Eurodollar Loan shall bear interest
(which the  relevant  Borrower  promises  to pay in arrears at the times  herein
provided) on the unpaid  principal  amount thereof from time to time outstanding
from the date of the Borrowing of such Eurodollar  Loan until maturity  (whether
by  acceleration  or  otherwise)  at a rate  per  annum  equal to the sum of the
Applicable Margin plus Adjusted LIBOR, payable on the last day of the applicable
Interest Period and at maturity (whether by acceleration or otherwise),  and, if
the  applicable  Interest  Period  is  longer  than  three  months,  on the date
occurring  three months after the date of the  Borrowing of such Loan;  provided
that if a  Eurodollar  Loan is not paid when due  (whether  by  acceleration  or
otherwise),  such Loan shall bear interest (which the relevant Borrower promises
to pay at the times  herein  provided)  from the date such payment was due until
paid in full,  payable on demand, at the rate per annum specified in Section 1.9
hereof.

     Section 2.3. Rate  Determinations.  The Agent shall determine each interest
rate  applicable  to  the  Loans  hereunder  in  accordance  herewith,  and  its
determination thereof shall be deemed prima facie correct.

     Section 2.4.  Computation of Interest.  All interest on Domestic Rate Loans
shall be computed on the basis of a year of 365 or 366 days, as the case may be,
for the actual  number of days  elapsed.  All interest on  Eurodollar  Loans and
Swing Loans bearing  interest at the Agent's  Quoted Rate (and unless  otherwise
stated  herein,  all fees,  charges  and  commissions  due  hereunder)  shall be
computed  on the  basis  of a year of 360  days for the  actual  number  of days
elapsed,  except for Eurodollar Loans denominated in Pounds Sterling which shall
be computed on the basis of a year of 365 or 366 days, as the case may be.

     Section 2.5. Funding Indemnity. If any Lender shall incur any loss, cost or
expense (including,  without limitation,  any loss of profit, and any loss, cost
or expense incurred by reason of the liquidation or re-employment of deposits or
other funds acquired by such Lender to fund or maintain any  Eurodollar  Loan or
Swing Loan or the relending or  reinvesting  of such deposits or amounts paid or
prepaid to such Lender) as a result of:

               (i) any payment or prepayment of a Eurodollar  Loan or Swing Loan
          on a date  other  than  the last day of its  Interest  Period  for any
          reason,

               (ii) any failure  (because of a failure to meet the conditions of
          Borrowing or otherwise) by a Borrower to borrow or refund a Eurodollar
          Loan or Swing Loan on the date specified in a notice given pursuant to
          this Agreement,

               (iii) any failure by a Borrower to make any payment of  principal
          on any Eurodollar Loan or Swing Loan when due (whether by acceleration
          or otherwise), or

               (iv) any  acceleration  of the maturity of a  Eurodollar  Loan or
          Swing  Loan as a result  of the  occurrence  of any  Event of  Default
          hereunder,

then, upon the demand of such Lender, the applicable  Borrower shall pay to such
Lender such amount as will reimburse such Lender for such loss, cost or expense.
If any  Lender  makes  such a claim for  compensation,  it shall  provide to the
Company,  with a copy to the Agent, a certificate executed by an officer of such
Lender  setting  forth the  amount of such loss,  cost or expense in  reasonable
detail  (including an explanation  of the basis for and the  computation of such
loss, cost or expense) and the amounts shown on such certificate shall be deemed
prima facie correct.

     Section 2.6. Change of Law.  Notwithstanding  any other  provisions of this
Agreement or any Note, if at any time any change in applicable law or regulation
or in the  interpretation  thereof  makes it unlawful  for any Lender to make or
continue to maintain Loans in an Alternative  Currency or Eurodollar Loans, such
Lender shall  promptly  give notice  thereof to the  Borrower and such  Lender's
obligations  to make or  maintain  Eurodollar  Loans or Loans in an  Alternative
Currency (as  applicable)  under this Agreement  shall  terminate until it is no
longer  unlawful for such Bank to make or maintain  such Loans.  The  applicable
Borrower  shall prepay on demand the  outstanding  principal  amount of any such
affected Loans, together with all interest accrued thereon and all other amounts
then due and payable to such Lender  under this  Agreement;  provided,  however,
subject to all of the terms and  conditions of this  Agreement,  the  applicable
Borrower may then elect to borrow the  principal  amount of the  affected  Loans
from such Lender by means of  Domestic  Rate Loans which Loans shall not be made
ratably by the Lenders but only from such affected Lender.

     Section 2.7.  Unavailability.  If prior to the commencement of any Interest
Period for any Borrowing of Eurodollar Loans:

          (a) the Agent determines that deposits in the applicable  currency (in
     the  applicable  amounts) are not being  offered to it in the  eurocurrency
     interbank  market  for  such  Interest   Period,   or  that  by  reason  of
     circumstances  affecting the  interbank  eurocurrency  market  adequate and
     reasonable means do not exist for ascertaining the applicable LIBOR, or

          (b) the Required Lenders notify the Agent that (i) LIBOR as determined
     by the  Agent  will not  adequately  and  fairly  reflect  the cost to such
     Lenders  of  funding  their  Loans in the  currency  in  question  for such
     Interest Period or (ii) that the making or funding of Loans in the relevant
     currency has become  impracticable,  in either case as a result of an event
     occurring  after  the date  hereof  which in the  opinion  of such  Lenders
     materially adversely affects such Loans,

then and in any such  event the Agent  shall not less than two days prior to the
commencement of such Interest Period, give notice thereof to the Company and the
Lenders,  whereupon until the Agent notifies the Company that the  circumstances
giving rise to such  suspension no longer exist,  the obligations of the Lenders
to make  Loans in the  currency  so  affected  or to make  Eurodollar  Loans (as
applicable) shall be suspended.

     Section 2.8.  Increased Cost and Reduced  Return.  If, on or after the date
hereof,  the adoption of any applicable  law, rule or regulation,  or any change
therein,  or any change in the  interpretation or administration  thereof by any
governmental  authority,  central  bank or  comparable  agency  charged with the
interpretation  or administration  thereof,  or compliance by any Lender (or its
lending  office) with any request or directive  (whether or not having the force
of law) of any such authority, central bank or comparable agency:

               (i) shall subject any Lender (or its applicable  lending  office)
          to any tax, duty or other charge with respect to any of its Eurodollar
          Loans,  its Revolving  Credit Notes,  its Letter(s) of Credit,  or its
          participation in any thereof, or its obligation to make Loans, issue a
          Letter of Credit, or to participate therein, or shall change the basis
          of  taxation  of  payments  to any Lender (or its  applicable  lending
          office)  of the  principal  of or  interest  on any of its  Eurodollar
          Loans,  Letter(s) of Credit,  or  participations  therein or any other
          amounts due under this Agreement in respect of its  Eurodollar  Loans,
          Letter(s) of Credit,  or  participations  therein or its obligation to
          make  Eurodollar   Loans,   issue  a  Letter  of  Credit,  or  acquire
          participations  therein  (except for changes in the rate of tax on the
          overall net income of such Lender or its lending office imposed by the
          jurisdiction  in which such  Lender's  principal  executive  office or
          applicable lending office is located); or

               (ii) shall impose, modify or deem applicable any reserve, special
          deposit or similar requirement  (including,  without  limitation,  any
          such  requirement  imposed by the Board of  Governors  of the  Federal
          Reserve  System,  but excluding  with respect to any such  requirement
          included in an applicable  Eurocurrency  Reserve  Percentage)  against
          assets of, deposits with or for the account of, or credit extended by,
          any Lender (or its applicable  lending  office) or shall impose on any
          Lender (or its lending  office) or on the  interbank  market any other
          condition  affecting its Revolving  Loans, its Revolving Credit Notes,
          its Letter(s) of Credit, or its  participation in any thereof,  any of
          its obligation to make Revolving  Loans,  to issue a Letter of Credit,
          or to participate therein;

and the result of any of the  foregoing  is to increase  the cost to such Lender
(or its  lending  office) of making or  maintaining  any  Revolving  Loan in the
currency   requested  or  issuing  or   maintaining  a  Letter  of  Credit,   or
participating therein, or to reduce the amount of any sum received or receivable
by such Lender (or its applicable  lending office) under this Agreement or under
its Notes with respect thereto, by an amount in each case deemed by such Lender,
in its reasonable judgment, to be material, then, within fifteen (15) days after
demand by such Lender (with a copy to the Agent), the Company shall be obligated
to pay to such Lender such additional  amount or amounts as will compensate such
Lender for such increased cost or reduction.

     Each Lender that  determines  to seek  compensation  under this Section 2.8
shall  notify the Company and the Agent of the  circumstances  that  entitle the
Lender to such  compensation  pursuant to this Section 2.8 and will  designate a
different  lending office if such designation will avoid the need for, or reduce
the amount of, such  compensation  and will not, in the  reasonable  judgment of
such Lender, be otherwise  disadvantageous  to such Lender. A certificate of any
Lender  claiming  compensation  under this  Section  2.8 and  setting  forth the
additional  amount or amounts to be paid to it  hereunder  shall be deemed prima
facie correct.  In determining  such amount,  such Lender may use any reasonable
averaging and attribution methods.

     Section 2.9. Lending Offices. Each Lender may, at its option, elect to make
its  Loans  hereunder  at the  branch,  office  or  affiliate  specified  on the
appropriate  signature  page hereof  (each a "Lending  Office") for each type of
Revolving Loan available hereunder or at such other of its branches,  offices or
affiliates  as it may from time to time elect and  designate  in a notice to the
Company  and the Agent (but such funds shall in any event be made  available  to
the Company at the office of the Agent as herein  provided  for),  provided that
the  Company  shall not be  required to  reimburse  any Lender  under any of the
provisions  of this  Section 2 for any cost  which  such  Lender  would not have
incurred  but for  changing  its  lending or funding  branch  unless the Company
consented in writing to such change.

     Section 2.10. Discretion of Lender as to Manner of Funding. Notwithstanding
any other provision of this Agreement, each Lender shall be entitled to fund and
maintain  its funding of all or any part of its Loans in any manner it sees fit,
it being  understood,  however,  that for the  purposes  of this  Agreement  all
determinations under this Agreement shall be made as if each Lender had actually
funded and maintained  each  Eurodollar Loan through the purchase of deposits in
the relevant market and in the relevant currency having a maturity corresponding
to such Eurodollar  Loan's Interest Period and bearing an interest rate equal to
Adjusted LIBOR for the currency in question for such Interest Period.

     Section 2.11.  Capital  Adequacy.  If any Lender shall  determine  that any
applicable law, rule or regulation  regarding capital adequacy  instituted after
the date hereof,  or any change in the  interpretation  or administration of any
applicable  law,  rule  or  regulation   regarding   capital   adequacy  by  any
governmental  authority,  central  bank or  comparable  agency  charged with the
interpretation  or  administration  thereof or compliance by such Lender (or its
lending  office)  with any  request  or  directive  regarding  capital  adequacy
(whether or not having the force of law) of any such authority,  central bank or
comparable  agency,  has or would have the effect of reducing the rate of return
on such Lender's  capital as a consequence of its  obligations  hereunder or the
Letters of Credit or credit extended by it hereunder to a level below that which
such Lender could have achieved but for such law,  rule,  regulation,  change or
compliance  (taking into  consideration  such Lender's  policies with respect to
capital  adequacy) by an amount reasonably deemed by such Lender to be material,
then from time to time as  specified  by such  Lender the  Company  shall pay on
demand such additional amount or amounts as will compensate such Lender for such
reduction.  A certificate of any Lender claiming compensation under this Section
2.11 and  setting  forth  the  additional  amount  or  amounts  to be paid to it
hereunder  in  reasonable  detail  shall be prima  facie  evidence  thereof.  In
determining  such  amount,  such  Lender may use any  reasonable  averaging  and
attribution methods.

SECTION 3. FEES, PAYMENTS, REDUCTIONS, APPLICATIONS AND NOTATIONS.

     Section  3.1.  Commitment  Fee. For the period from the Closing Date to and
including the  Termination  Date,  the Borrowers  shall pay to the Agent for the
account of the  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  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
0.05%.  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.

     Section 3.2.  Other Fees. The Company shall pay to the Agent such other and
additional  fees as may from time to time be agreed to between  the  Company and
the Agent.

     Section 3.3.  Letter of Credit Fees. The applicable  Borrowers shall pay to
the Agent,  for the ratable  account of the Lenders,  a fee on the amount of the
L/C  Obligations  from time to time  outstanding  computed (i) at the Applicable
Margin in the case of Financial Letters of Credit and (ii) the Applicable Margin
less the  rate of 3/4 of 1% per  annum in the  case of  Performance  Letters  of
Credit,  subject to a minimum of 0.50% (in each case  computed on the basis of a
year of 360 days and actual days  elapsed),  each such fee to be due and payable
quarterly  in  arrears  on the  last  day of each  calendar  quarter  and on the
Termination Date. In addition,  on the date of issuance of each Letter of Credit
the applicable  Borrower shall pay the Applicable  Issuer for its own account an
issuance fee of 1/8 of 1% of the face amount of such Letter of Credit,  such fee
to be retained by the Applicable  Issuer for its own account.  In addition,  the
applicable Borrower shall pay to the Applicable Issuer such issuing, processing,
drawing,  amendment  and  other  fees  and  charges  as  the  Applicable  Issuer
customarily  imposes in connection with the issuance of letters of credit of the
type in question, the payment of drafts thereunder or amendments thereto.

     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 three (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.

     Section  3.5.  Mandatory   Prepayments  and  Commitment   Reductions.

          (a)  Commitments.  In the event that the aggregate amount of Revolving
     Loans, Swing Loans and L/C Obligations shall at any time and for any reason
     exceed the Commitments or the aggregate  amount of Revolving  Loans,  Swing
     Loans  and L/C  Obligations  owing  from  any  Borrower  shall  exceed  any
     applicable  Sublimit,  in each case for any  reason  (including  changes in
     currency  rates),  the Borrowers  shall  immediately  and without notice or
     demand  pay the  amount of the  excess to the Agent as and for a  mandatory
     prepayment  on the Revolving  Credit Notes or, if the Revolving  Loans have
     been paid in full but L/C Obligations are outstanding, then and in any such
     event,  such excess shall be paid over to the Agent to be applied  against,
     or held as collateral security for, as applicable, such L/C Obligations.

          (b)  Asset  Dispositions.  (i)  If  any  Borrower  or  any  Restricted
     Subsidiary  shall at any time or from  time to time make or agree to make a
     Disposition or shall suffer an Event of Loss resulting in Net Cash Proceeds
     in excess of $5,000,000 individually or on a cumulative basis in any fiscal
     year of the Borrowers,  to the extent the aggregate  amount of all such Net
     Cash Proceeds  received by the Borrowers  and the  Restricted  Subsidiaries
     during the period from and  including  the date hereof to and including the
     date of such  Disposition  or Event of Loss exceed 10% of the book value of
     assets of the Borrowers and the  Restricted  Subsidiaries  as of such date,
     then (x) the  Company  shall  promptly  notify  the Agent of such  proposed
     Disposition  or Event of Loss  (including  the amount of the  estimated Net
     Cash Proceeds to be received by such Borrower or such Subsidiary in respect
     thereof)  and (y) such Net Cash  Proceeds  shall be paid  over to the Agent
     promptly upon receipt by such Borrower or such Restricted Subsidiary of the
     Net Cash Proceeds of such  Disposition or Event of Loss for  application as
     set  forth  herein.  Immediately  upon  receipt  by the  Borrower  or  such
     Restricted  Subsidiary of such Net Cash  Proceeds,  the  Commitments  shall
     ratably terminate in an aggregate amount equal to 100% of the amount of all
     such Net Cash  Proceeds and the Agent shall apply such Net Cash Proceeds to
     the payment of all  amounts,  if any,  required by Section  3.5(c)  hereof;
     provided that in the case of each  Disposition and Event of Loss so long as
     no Default or Event of Default shall have occurred and is then  continuing,
     if the  Company  states in its  notice of such  event  that the  applicable
     Borrower or the applicable Subsidiary intends to reinvest,  within 180 days
     of the applicable Disposition or receipt of Net Cash Proceeds from an Event
     of Loss,  the Net Cash  Proceeds  thereof  in assets  similar to the assets
     which were  subject to such  Disposition  or Event of Loss,  then the Agent
     shall  deposit  such Net Cash  Proceeds in the  Collateral  Account and the
     Commitments  shall not so  terminate  under this Section to the extent such
     Net Cash  Proceeds are actually  reinvested  in such similar  assets within
     such 180-day period.  Concurrently  with any such  reinvestment,  the Agent
     shall return the amount of such Net Cash  Proceeds to be  reinvested to the
     Company.  Promptly after the end of such 180-day period,  in the event that
     the applicable Borrower or Restricted  Subsidiary has not reinvested any of
     such Net Cash  Proceeds  in such  similar  assets,  the  Commitments  shall
     immediately  terminate in an amount equal to 100% of such Net Cash Proceeds
     and the Agent shall promptly apply such Net Cash Proceeds to the payment of
     all  amounts,  if any,  required  by Section  3.5(c)  below and release the
     balance  thereof to the  Company.  In the event and to the extent  that any
     Commitment  reduction  pursuant to this  Section  3.5(b) does not require a
     prepayment of Loans or prefunding  of L/C  Obligations  pursuant to Section
     3.5(c)  below,  the Agent shall  promptly  return the Net Cash Proceeds not
     required for such purpose to the Company.

          (c) Commitment  Terminations.  The Borrowers  shall,  on each date the
     Commitments  are reduced  pursuant to Section 3.5(b) or 3.6 hereof,  prepay
     the  Revolving  Loans,  Swing  Loans,  and, if  necessary,  prefund the L/C
     Obligations  by the amount  necessary  to reduce  the sum of the  aggregate
     principal amount of Revolving Loans,  Swing Loans, and L/C Obligations then
     outstanding to the amount to which the Commitments have been so reduced.

     Section 3.6. Voluntary Terminations. The Borrowers shall have the privilege
without  any  penalty or fee 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 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,  unless the Commitments shall be less
than $5,000,000);  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.

     Section 3.7. Place and Application. All payments of principal, interest and
fees  shall  be made to the  Agent at its  office  at 111  West  Monroe  Street,
Chicago,  Illinois  (or at  such  other  place  as the  Agent  may  specify)  in
immediately  available and freely  transferable funds at the place of payment by
no later  than  12:00  Noon  Central  Time on the due date  thereof  or, if such
payment is to be made in an  Alternative  Currency,  by no later than 12:00 Noon
local time at the place of payment  to such  office as the Agent has  previously
specified;  provided  however that  reimbursements  of drawings under Letters of
Credit shall be made to the  Applicable  Issuer.  Any  payments  received by the
Agent or such  Applicable  Issuer after such time shall be deemed received as of
the opening of business on the next  Business  Day. All such  payments  shall be
made  (i) in U.S.  Dollars,  in  immediately  available  funds  at the  place of
payment,  or (ii) in the case of Revolving  Loans or  reimbursement  of drawings
under a  Letter  of  Credit  in an  Alternative  Currency,  in such  Alternative
Currency  in  such  funds  then  customary  for   settlement  of   international
transactions  in such currency.  All such payments shall be made without set-off
or counterclaim and without reduction for, and free from, any and all present or
future taxes, levies, imposts, duties, fees, charges, deductions,  withholdings,
restrictions  or conditions of any nature imposed by any government or political
subdivision or taxing authority thereof. Except as herein provided, all payments
shall  be  received  for  the  ratable  account  of the  Lenders  and  shall  be
distributed by the Agent to the Lenders in accordance with their  Percentages on
the date the Agent receives payment, or if the Agent receives payment later than
12:00 Noon Central  Time,  then no later than the next  Business Day. Any amount
prepaid  on the  Revolving  Credit  Notes  may,  subject to all of the terms and
conditions hereof, be borrowed, repaid and borrowed again. Unless the applicable
Borrower  otherwise  requests,  each  prepayment  shall be first applied to such
Borrower's  Domestic Rate Loans and then to its Eurodollar Loans in the order in
which their Interest Periods expire. Any prepayment of Eurodollar Loans shall be
accompanied  by any  amount  due  the  Lenders  under  Section  2.5  hereof  but
acceptance  of any such  prepayment  without such a payment being made shall not
preclude a later demand by the Lenders for such payment.

     Anything contained herein to the contrary notwithstanding, all payments and
collections  received  in respect of the  Obligations  and all  proceeds  of the
Collateral received,  in each instance, by the Agent or any of the Lenders after
the  occurrence  of an Event of  Default  shall be  remitted  to the  Agent  and
distributed as follows:

          (a)  first,  to the  payment  of any  outstanding  costs and  expenses
     incurred by the Agent in monitoring,  verifying, protecting,  preserving or
     enforcing  the  Liens on the  Collateral  or by the  Agent  in  protecting,
     preserving or enforcing  rights under the Loan Documents,  and in any event
     all costs and expenses of a character  which the  Borrowers  have agreed to
     pay under  Section  11.5 hereof (such funds to be retained by the Agent for
     its own account  unless the Agent has previously  been  reimbursed for such
     costs and  expenses by the Lenders,  in which event such  amounts  shall be
     remitted to the Lenders to reimburse them for payments  theretofore made to
     the Agent);

                   (b) second, to the payment of principal and interest on the
         Swing Note until paid in full;

                   (c) third, to the payment of any outstanding interest or
         other fees or amounts due under the Revolving Credit Notes and the
         other Loan Documents, in each case other than for principal or in
         reimbursement or collateralization of L/C Obligations, ratably as among
         the Agent and the Lenders in accord with the amount of such interest
         and other fees or amounts owing each;

                   (d) fourth, to the payment of the principal of the Revolving
         Credit Notes and any unpaid Reimbursement Obligations and to the Agent
         to be held as collateral security for any other L/C Obligations (until
         the Agent is holding an amount of cash equal to the then outstanding
         amount of all such L/C Obligations), and Hedging Liability, the
         aggregate amount paid to or held as collateral security for the Lenders
         and, in the case of Hedging Liability, their Affiliates, to be
         allocated pro rata in accordance with the then aggregate unpaid amounts
         owing to each holder thereof;

                   (e) fifth, to the Agent and the Lenders ratably in accordance
         with the amounts of any other indebtedness, obligations or liabilities
         of the Borrowers owing to each of them and secured by the Collateral
         Documents unless and until all such indebtedness, obligations and
         liabilities have been fully paid and satisfied; and

                   (f) sixth, to the Company on behalf of the Borrowers (each
         Borrower hereby agreeing that its recourse for its share of such
         payment shall be to the Company and not the Agent or any Lender) or
         whoever else may be lawfully entitled thereto.

     Section  3.8.  Notations  and  Requests.  All  Borrowings  made against the
Revolving  Credit  Notes  or the  Swing  Note,  the  Borrower  which  made  such
Borrowings,  the rates of interest applicable thereto,  the maturity thereof and
the currency in which each such Borrowing is  denominated,  shall be recorded by
the Lenders on their books or, at their option in any instance,  endorsed on the
reverse side of the Revolving Credit Notes or Swing Note, as applicable, and the
unpaid  principal  balances  and  status,  rates and  currencies  so recorded or
endorsed  by the  Lenders  shall be prima  facie  evidence in any court or other
proceeding  brought to enforce the  Revolving  Credit Notes or Swing Note of the
principal  amount  remaining  unpaid  thereon,   the  Borrower  which  made  the
Borrowings  evidenced  thereby,  the  currencies  in which such  Borrowings  are
payable,  the interest rates applicable thereto and the maturity thereof.  Prior
to any  negotiation  of any  Revolving  Credit  Note or Swing  Note,  the Lender
holding such Revolving Credit Note shall endorse thereon the outstanding  amount
of Borrowings  evidenced thereby,  the currencies in which the same are payable,
the rates of interest applicable thereto and the maturities thereof.

SECTION 4. THE COLLATERAL AND THE GUARANTEES.

     Section 4.1. The Collateral.  The Obligations and Hedging  Liability (i) of
the U.S.  Borrowers  shall be secured by valid and perfected  first Liens on all
inventory,  accounts  receivable,  equipment  and other  personal  property  (as
further  described in the  Collateral  Documents) of the U.S.  Borrowers and the
U.S.  Subsidiaries  which are Guarantors and,  subject to the provisions of this
Section 4.1, all capital stock of all Guarantors, together with all instruments,
securities,  chattel paper and  intangibles  of the U.S.  Borrowers and the U.S.
Subsidiaries which are Guarantors and all proceeds of the foregoing, and (ii) of
the U.K.  Borrowers  and the  Canadian  Borrowers  shall be secured by valid and

and  until the  Required  Lenders  otherwise  elect  (i) the  Borrowers  and the
Guarantors  shall not be required to note the Agent's Lien on any certificate of
title  issued  for a  vehicle  or to  perfect  a Lien on  fixtures  and  (ii) no
Guarantor,  the fair market value of whose assets aggregate less than $1,000,000
shall be required to grant  Liens on its assets to the Agent,  further  provided
that (i) Liens on (a) any contract (or  modification  thereof) (a "Contract") to
which any  Guarantor  is a party  ("Contractor"),  the  performance  of which is
guaranteed   by  any  bond,   undertaking,   instrument   of  guarantee  or  any
continuation,  extension,  alteration, renewal or substitution thereof, executed
by any bonding  company of a Contractor;  (b) any  subcontract or purchase order
and against any legal entity and its bonding company which has contracted with a
Contractor to furnish labor,  materials,  equipment,  and supplies in connection
with any  Contract;  (c)  monies,  Contract  balances,  due or to become due any
Contractor  on any Contract,  including all monies earned or unearned  which are

any actions,  causes of action,  claims or demands whatsoever which a Contractor
may have or  acquire  against  any party to a Contract  or arising  out of or in
connection  with any  Contract,  including  but not  limited  to  those  against
obligees and design  professionals  any bonding company or binding  companies of
any obligee; (e) any and all rights,  title,  interest in, or use of any patent,
copyright or trade secret which is or may be necessary for the completion of any
bonded work;  (f) all monies due or to become due to a Contractor  on any policy
of  insurance  relating  to any claims  arising  out of the  performance  of any
Contract or to premium  refunds,  including,  but not limited to, builders risk,
fire, employee dishonesty or workers' compensation  policies;  (g) all supplies,
tools,   plants,   material,   inventory,   and  equipment  (whether  completely
manufactured  or not),  wherever  located,  which have been or hereafter  may be
purchased,  used, or acquired for use, entirely or partly, in connection with or
to be incorporated into the matter that is the subject of any Contract;  and (h)
all  amounts  that may be owing  from  time to time by a  bonding  company  to a
Contractor or any Guarantor in any capacity including,  without limitation,  any
balance or share  belonging  to such  Contractor  or Guarantor or any deposit or
other account with a bonding company,  may be subject to prior Liens in favor of
bonding  companies to secure  obligations  in  connection  with such payment and
performance  bonds;  (ii) no Lien need be granted on any asset subject to a lien
permitted by Section 7.11(e), (i), (l) (as to Liens on fixed assets only) or (m)
(iii) no Lien need be granted on the capital stock of an Unrestricted Subsidiary
or on the capital stock or assets of Designated Foreign Restricted Subsidiaries,
(iv) no Liens  need be granted on real  property  unless and until the  Required
Lenders so require,  (v) Liens granted may be subject and  subordinate  to Liens
permitted by clauses (a),  (b),  (c), (e), (f), (g), (h), (j), (k), (n), (o) and
(q) of Section 7.11 hereof,  (vi) Liens need not be perfected by  possession  or
control (but may be perfected by the filing of a financing  statement)  on notes
receivable  having a fair  value of less than  $1,000,000  in any  instance  and
$5,000,000 in the aggregate or on bonds or notes pledged to the City of New York
in lieu of retainage, (vii) Liens need not be perfected by possession or control
(but  may be  perfected  by the  filing  of a  financing  statement)  on  equity
securities  (other than capital stock of Restricted  Subsidiaries  to the extent
required hereby) having a fair value of less than $1,000,000 in any instance and
[$5,000,000]  in the  aggregate  and  (viii)  no  lien  need be  granted  on any
contract,  license,  permit or franchise,  that validly  prohibits the creation,
attachment,  or  perfection  of a security  interest  in favor of the Agent of a
security  interest in such  contract,  license,  permit or franchise  (or in any
rights or property obtained by such Person under such contract,  license, permit
or  franchise),  (ix) no lien need be granted on any rights or  property  to the
extent  that any valid and  enforceable  law or  regulation  applicable  to such
rights or property  prohibits the creation of a security interest  therein,  and
(x) no lien need be granted on any rights or  property  to the extent  that such
rights or property secure purchase money  financing  therefor  permitted by this
Credit  Agreement and the agreements  providing  such purchase  money  financing
prohibit the creation of a further  security  interest  therein.  The  Borrowers
agree that they will, and will cause the Guarantors to, from time to time at the
request of the Agent or the Required Lenders execute and deliver such documents,
security agreements, assignments, pledges, hypothecs or charges and do such acts
and things as the Agent or the Required Lenders may reasonably  request in order
to provide for or perfect such Liens on the Collateral. Notwithstanding anything
to the contrary  contained herein or in any other Loan Document,  the Collateral
owned by the U.K Subsidiaries and the Canadian  Subsidiaries  (including without
limitation   equity   interests   in  other  U.K.   Subsidiaries   and  Canadian
Subsidiaries) shall secure solely the indebtedness,  liabilities and obligations
of the U.K. Subsidiaries and the Canadian  Subsidiaries  hereunder and under the
other Loan Documents and not the  indebtedness,  liabilities  and obligations of
the U.S. Borrowers and the U.S. Subsidiaries  hereunder and under the other Loan
Documents.  Notwithstanding  the foregoing,  the portion of the capital stock of
each U.K.  Subsidiary and Canadian  Subsidiary  owned by a U.S.  Corporation and
constituting  Collateral  in excess of 65% of the total  issued and  outstanding
capital stock of such Subsidiary  (herein,  the "Excess Stock Collateral") shall
secure  only  the  indebtedness  liabilities  and  obligations  of the  Canadian
Subsidiaries  and/or  U.K.  Subsidiaries  hereunder  and under  the  other  Loan
Documents.   In  no  event  shall  the  Excess  Stock   Collateral   secure  the
indebtedness,  liabilities  and  obligations  of the U.S.  Borrowers or the U.S.
Subsidiaries  hereunder or under the other Loan Documents.  Notwithstanding  the
foregoing,  no Lien need be granted on the capital stock of a captive  insurance
company or captive  surety  company if the  granting of such Lien would  violate
applicable law or require the consent of any applicable regulatory body.

     Section 4.2. The Guarantees.  The Obligations and Hedging  Liability (i) of
the U.S.  Borrowers  shall  be  fully  guaranteed  by the  Company  and the U.S.
Subsidiaries  which  are  Guarantors  and  (ii) of the  U.K.  Borrowers  and the
Canadian  Borrowers  shall  be  fully  guaranteed  by  the  Company,   the  U.S.
Subsidiaries,  the U.K.  Subsidiaries and the Canadian Subsidiaries in each case
which are Guarantors. Subject to 4.1, the Required Lenders may from time to time
require any Restricted Subsidiary (other than Restricted  Subsidiaries which are
not  Wholly-Owned  Subsidiaries  and any  captive  insurance  company or captive
surety  company  which is a Restricted  Subsidiary)  to provide a Guarantee  and
Liens on its assets in which event the Company  shall  within 30 days of request
cause such Restricted Subsidiary to execute and deliver a Guarantee to the Agent
together with such  supporting  resolutions,  opinions and other showings as the
Agent may reasonably require.

SECTION 5. REPRESENTATIONS AND WARRANTIES.

     Each  Borrower  represents  and  warrants  to the Agent and the  Lenders as
follows:

     Section  5.1.  Organization  and  Qualification.   Each  Borrower  is  duly
organized,  validly  existing and in good standing (or their  equivalents  under
applicable local law) as a corporation, limited liability company or partnership
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.

     Section  5.2.  Subsidiaries.  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 or in good
standing would have a Material Adverse Effect.  As of the date hereof,  Schedule
5.2 hereto  identifies  each  Restricted  Subsidiary,  the  jurisdiction  of its
incorporation or organization,  as the case may be, the percentage of issued and
outstanding  shares of each class of its capital stock or other equity interests
owned by the Company and the Restricted  Subsidiaries and, if such percentage is
not 100%  (excluding  directors'  qualifying  shares  as  required  by  law),  a
description  of each  class of its  authorized  capital  stock and other  equity
interests and the number of shares of each class issued and  outstanding and the
Company will notify the Agent of any material changes in such  information.  All
of the  outstanding  shares of capital stock and other equity  interests of each
such   Subsidiary  are  validly  issued  and  outstanding  and  fully  paid  and
nonassessable  (except  for  the  provisions  of  Section  630 of  the  Business
Corporation Law of the State of New York, as to New York Corporations) and as of
the date hereof all such shares and other equity interests indicated on Schedule
5.2 as owned by the Company or a Restricted Subsidiary are as of the date hereof
owned,  beneficially and of record, by the Company or such Restricted Subsidiary
free and clear of all  Liens  not  permitted  hereby.  There are no  outstanding
commitments or other  obligations of any Restricted  Subsidiary to issue, and no
options,  warrants or other  rights of any Person to acquire,  any shares of any
class of capital stock or other equity  interests of any  Restricted  Subsidiary
except in favor of the Company or a Restricted Subsidiary.

     Section 5.3. Corporate Authority and Validity of Obligations. Each Borrower
has full right and  authority  to enter into this  Agreement  and the other Loan
Documents to which it is a party, to make the borrowings herein provided for, to
issue the Revolving Credit Notes in evidence thereof,  to grant to the Agent the
Liens  provided for in the  Collateral  Documents  being  executed by it, and to
perform all of its  obligations  hereunder and under the other Loan Documents to
which it is a party.  Each  Guarantor has full right and authority to enter into
the Loan  Documents  to which it is a party,  to grant to the  Agent  the  Liens
provided for in the  Collateral  Documents  executed by it and to perform all of
its  obligations  under such Loan  Documents.  The Loan Documents have been duly
authorized,   executed  and  delivered  by  the  Borrowers  and  Guarantors  and
constitute  valid  and  binding  obligations  of the  Borrowers  and  Guarantors
enforceable  in  accordance  with their terms  except as  enforceability  may be
limited by bankruptcy,  insolvency or similar laws affecting  creditors'  rights
generally  and  general   principles  of  equity   (regardless  of  whether  the
application  of such  principles  is  considered in a proceeding in equity or at
law);  and this  Agreement  and the other Loan  Documents  do not,  nor does the
performance or observance by any Borrower or Guarantor of any of the matters and
things herein or therein provided for,  contravene or constitute a default under
any provision of law or any judgment,  injunction,  order or decree binding upon
any  Borrower  or  Guarantor  or any  provision  of  the  charter,  articles  of
incorporation  or  organization  or by-laws of any  Borrower or Guarantor or any
covenant, indenture or agreement of the Borrowers or Guarantors or affecting any
of their Properties,  or result in the creation or imposition of any Lien on any
Property of the Borrowers or Guarantors.

     Section 5.4. Use of Proceeds;  Margin Stock.  The  Borrowers  shall use the
proceeds of the Revolving  Loans and other  extensions of credit made  available
hereunder solely for their general corporate purposes (including ordinary course
of business refunding of indebtedness and acquisitions and investments permitted
hereunder).  Neither the Borrowers nor any Subsidiary is engaged in the business
of  extending  credit for the purpose of  purchasing  or carrying  margin  stock
(within the meaning of  Regulation  U of the Board of  Governors  of the Federal
Reserve System),  and no part of the proceeds of any Revolving Loan or any other
extension  of credit made  hereunder  will be used to purchase or carry any such
margin  stock or to extend  credit to others for the  purpose of  purchasing  or
carrying any such margin stock.

     Section 5.5.  Financial  Reports.  The  consolidated  balance  sheet of the
Company  and  its   Subsidiaries  as  at  December  31,  2004  and  the  related
consolidated  statements of operations,  cash flows and shareholder's  equity of
the  Company  and  its   subsidiaries  for  the  fiscal  year  then  ended,  and
accompanying  notes  thereto,   which  consolidated   financial  statements  are
accompanied by the audit report of Ernst & Young LLP, an independent  registered
public accounting firm, and the unaudited interim condensed consolidated balance
sheet of the  Company and its  subsidiaries  as at June 30, 2005 and the related
interim  condensed  consolidated  statements  of  operations,   cash  flows  and
shareholder's  equity of the Company and its subsidiaries for the six (6) months
then ended heretofore furnished to the Lenders,  fairly present the consolidated
financial condition of the Company and its subsidiaries as at said dates and the
results  of their  operations  and cash  flows  for the  periods  then  ended in
conformity with generally accepted accounting principles applied on a consistent
basis, but subject, in the case of such interim condensed  financial  statements
on the related notes thereto (the "Notes"),  to year end audit adjustments which
are not  expected  to be  material.  Neither  the  Company  nor  any  Restricted
Subsidiary has, to the best of its knowledge, contingent liabilities which could
reasonably be expected to have a Material Adverse Effect other than as indicated
on such financial  statements or, as to each  reaffirmation  of this  sentence's
representation  and  warranty  in the  future,  on  the  most  recent  financial
statements  or the related notes thereto which are to be provided to the Lenders
pursuant to Section 7.5 hereof or other than as set forth in that  certain  Side
Letter dated October 14, 2005 from the Company to the Agent (the "Side Letter").

     Section 5.6. No Material Adverse Change. Since December 31, 2004, there has
been no change in the condition  (financial or otherwise) or business  prospects
of the  Company  and its  Restricted  Subsidiaries  which  could  reasonably  be
expected to have a Material Adverse Effect.

     Section 5.7. Full Disclosure.  The statements and information  furnished by
or on behalf of the  Borrowers  to the Agent and the  Lenders  through  the date
hereof in connection  with the  negotiation of this Agreement and the other Loan
Documents  and the  commitments  by the  Lenders to  provide  all or part of the
financing  contemplated  hereby do not,  taken as a whole,  contain  any  untrue
statements  of a material  fact or omit a material  fact  necessary  to make the
material  statements  contained  herein or therein not  misleading,  the Lenders
acknowledging  that as to any  projections  furnished  to the  Lenders  by or on
behalf  of the  Borrowers,  the  Borrowers  only  represent  that the same  were
prepared on the basis of information and estimates the Borrowers  believed to be
reasonable.

     Section 5.8. Good Title.  Except to the extent heretofore  disclosed on the
Schedules to this  Agreement  or in the Side  Letter,  as of the date hereof the
Company and the Restricted  Subsidiaries have good and marketable title to their
real property and good and merchantable  title to the balance of their assets as
reflected on the most recent  balance  sheets of the Company and its  Restricted
Subsidiaries  furnished  to the  Lenders  (except  for  sales of  assets  by the
Borrowers and their Restricted Subsidiaries in the ordinary course of business),
subject to no Liens other than such  thereof as are  permitted  by Section  7.11
hereof.

     Section 5.9.  Litigation  and Other  Controversies.  Except as disclosed on
Schedule  5.9  hereof  or  in  the  Side  Letter,  there  is  no  litigation  or
governmental  proceeding or labor controversy  pending,  nor to the knowledge of
any Borrower threatened, against the Borrower or any Restricted Subsidiary which
if adversely  determined would (a) impair the validity or enforceability  of, or
impair the ability of any  Borrower  or  Guarantor  to perform  its  obligations
under,  this Agreement or any other Loan Document or (b) have a Material Adverse
Effect.

     Section 5.10.  Taxes.  All tax returns which,  to the best knowledge of the
Company, are required to be filed by the Company or any Restricted Subsidiary in
any jurisdiction have, in fact, been filed, and all taxes, assessments, fees and
other governmental charges upon the Company or any Restricted Subsidiary or upon
any of their respective Properties,  income or franchises, which are shown to be
due and payable in such returns,  have been paid to the extent due, in each case
except where the failure to do so would not cause a Material Adverse Effect. The
Borrowers do not know of any material proposed additional tax assessment against
them or the Restricted  Subsidiaries for which adequate  provision in accordance
with GAAP has not been made in their respective financial  statements.  Adequate
provisions in accordance  with GAAP for taxes on the books of the Company,  each
other Borrower and each Restricted Subsidiary have been made for all open years,
and for its current fiscal period.

     Section 5.11. Approvals. No authorization,  consent,  license, or exemption
from, or filing or  registration  with,  any court or  governmental  department,
agency or  instrumentality,  nor any approval or consent of the  stockholders of
the  Borrowers  or any  other  Person,  is or will  be  necessary  to the  valid
execution,  delivery or  performance  by the  Borrowers  or  Guarantors  of this
Agreement or any other Loan Document, other than the stockholders of Guarantors.

     Section  5.12.  Affiliate  Transactions.  No  Borrower  nor any  Restricted
Subsidiary  is a party to any contract or agreement  with any of its  Affiliates
(other  than  contracts  and  agreements  between  and among the  Borrowers  and
Restricted  Subsidiaries)  on terms and  conditions  which are less favorable to
such Borrower or such Restricted Subsidiary than would be usual and customary in
similar  contracts or agreements  between Persons not affiliated with each other

applicable  to it and has not incurred  any material  liability to the PBGC or a
Plan  (other  than   material   liabilities   arising  in  the  future  under  a
multiemployer  plan as defined in Section  4001(c)(3)  of ERISA  which could not
reasonably  be expected  to have a Material  Adverse  Effect)  under Title IV of
ERISA other than a material  liability  to the PBGC for premiums  under  Section

Health Act of 1970,  the Americans with  Disabilities  Act of 1990, and laws and
regulations establishing quality criteria and standards for air, water, land and
toxic or hazardous wastes and substances),  except for such  non-compliance with
the same which could not  reasonably  be expected to have any  Material  Adverse
Effect.  No Borrower nor any Restricted  Subsidiary  has received  notice to the
effect that its operations are not in compliance with any of the requirements of
applicable   federal,   governmental   (whether   national,   supra-national  or
otherwise), state, provincial or local environmental, health and safety statutes
and regulations or are the subject of any governmental  investigation evaluating
whether  any  remedial  action is needed to respond to a release of any toxic or
hazardous  waste or substance  into the  environment,  which  non-compliance  or
remedial action could reasonably be expected to have a Material Adverse Effect.

     Section 5.16. Other Agreements.  No Borrower nor any Restricted  Subsidiary
is in default  under the terms of any  covenant,  indenture  or  agreement of or
affecting the Borrowers,  any Restricted  Subsidiary or any of their Properties,
which default if uncured could reasonably be expected to have a Material Adverse
Effect.

is continuing.

     Section 5.18. Solvency.  Each Borrower is solvent, able to pay its debts as

each  Restricted  Subsidiary  to,  preserve  and keep in force  and  effect  its
corporate existence and all leases, licenses and permits necessary to the proper
conduct  of its and their  respective  businesses  except  with  respect  to any
Restricted  Subsidiary  to the  extent  that  the  failure  to do so  could  not
reasonably be expected to result in a Material Adverse Effect, provided that the
foregoing shall not preclude the termination or discontinuance of any of such in
connection with a sale or other  disposition of substantially  all of the assets
of the Restricted Subsidiary in question or the merger or dissolution of same in
each instance to the extent permitted by Section 7.14 hereof.

     Section 7.2. Maintenance of Property. The Borrowers will maintain, preserve

under contest and adequate reserves are provided therefor.

     Section 7.4.  Insurance.  The Borrowers  will insure and keep insured,  and
will cause each Restricted Subsidiary to insure and keep insured, with insurance

similarly  situated and operating  like  Properties  against loss or damage from
such hazards and risks, and in such amounts, as are insured by Persons similarly
situated and operating like Properties, and the Borrowers will insure, and cause
each Restricted  Subsidiary to insure,  such other hazards and risks  (including
employers'  and public  liability  risks) with  insurance  companies  reasonably
believed by them to be good and responsible as and to the extent usually insured
by Persons similarly situated and conducting similar businesses, it being agreed
that  the  foregoing  shall  not  preclude  the  Borrowers  and  the  Restricted
Subsidiaries  from  directly or  indirectly  self  insuring  risks as and to the

all or any  substantial  part of the Property of the Company and the  Restricted
Subsidiaries, taken as a whole, including any disposition of Property as part of
a sale and leaseback transaction (unless such transaction would be permitted had
it been  structured as a purchase money mortgage or Capital Lease and is treated
as such for purposes of this Agreement),  or in any event sell or discount (with
or without  recourse) any of its notes or accounts  receivable (other than sales
of accounts  receivable by the Company and its  Restricted  Subsidiaries  to any
Restricted  Subsidiary,  sale and leaseback  transactions between the Company or
any of its Restricted  Subsidiaries  and any Restricted  Subsidiary and sales or
discounts  of  doubtful  accounts  or notes  taken  in  satisfaction  of  same);
provided,  however,  that this  Section  7.14 shall not apply to nor  operate to
prevent the Borrowers or any of the Restricted  Subsidiaries  from selling their
inventory in the ordinary course of its business or from selling equipment which
is obsolete,  worn out, or no longer needed for the operation of the business of
the Company and the Restricted  Subsidiaries or which is promptly  replaced with
equipment of at least equal utility nor shall the foregoing prohibit (i) mergers
of  Restricted  Subsidiaries  with and into the Company and sales by  Restricted
Subsidiaries of all or  substantially  all of their assets to the Company,  (ii)
mergers  of  Restricted  Subsidiaries  with  each  other  and  sales  of  all or
substantially all of the assets of a Restricted Subsidiary to another Restricted
Subsidiary  provided  in  each  case  that  if  either  of  the  two  Restricted
Subsidiaries  in question is a  Guarantor,  the survivor of the  transaction  in
question  remains  a  Guarantor  and all such  actions  are  taken as the  Agent
requires to  preserve  its Liens on the  Collateral,  (iii) the  dissolution  or
liquidation of any Restricted  Subsidiary whose activities are no longer, in the
opinion of the Chief Executive Officer or the Board of Directors of the Company,
necessary  for the  operation of the business of the Company and its  Restricted
Subsidiaries  taken as a whole,  provided  always  that no  Default  or Event of
Default has  occurred  and is  continuing  or will result  therefrom  and if the
Restricted  Subsidiary to be dissolved or liquidated is a Guarantor,  all of its
assets   remaining   after  the  dissolution  or  liquidation  in  question  are
transferred to another Guarantor and all such actions,  if any, are taken as the
Agent may reasonably require in order to insure that it has a Lien on the assets
so  transferred  of the  priority  required  by  Section  4.1  hereof.  The term
"substantial"  as used  herein  shall  mean the sale,  transfer,  lease or other
disposition of assets of the Company or the Restricted Subsidiaries,  whether in
one or a series of transactions having a value when aggregated with the value of
assets of all other such sales,  transfers,  leases or other dispositions during
the period from and  including the date hereof to and including the date of such
sale, transfer,  lease or other disposition,  would exceed 10% of the book value
of assets of the Company and the  Restricted  Subsidiaries  as of such date. The
Agent shall  release its Lien on any  Property  sold  pursuant to the  foregoing
provisions  if no Default or Event of Default has occurred and is  continuing or
would result therefrom.

     Section 7.15. Maintenance of Restricted  Subsidiaries.  The Borrowers shall
not assign,  sell or transfer,  or permit any  Restricted  Subsidiary  to issue,
assign, sell or transfer, any shares of capital stock of a Restricted Subsidiary
(other than to the Company or another Restricted Subsidiary);  provided that the
foregoing  shall not operate to prevent (i) the  issuance,  sale and transfer to
any person of any shares of capital stock of a Restricted Subsidiary (a) for the
purpose of  qualifying,  and to the extent  legally  necessary to qualify,  such
person as a  director  of such  Subsidiary  or (b)  solely  for the  purpose  of
permitting such  Subsidiary to carry on a licensed  business or (ii) the sale of
all or a minority  interest in the capital  stock of a Restricted  Subsidiary if
but only if (a) no Default or Event of Default has occurred and is continuing or
will result from the sale of same,  (b) the sale of such capital  stock is not a
sale of a  substantial  part of the  assets of the  Company  and the  Restricted
Subsidiaries  taken as a whole (as the term  "substantial" is defined in Section
7.14 hereof),  (c) the Chief Executive  Officer or the Board of Directors of the
Company has determined that the continued ownership of the Restricted Subsidiary
(or the  minority  interest  therein to be disposed of) in question is no longer
appropriate  in light of the then needs and strategic  objectives of the Company
and its Restricted Subsidiaries taken as a whole and (d) in the case of the sale
of all the Capital Stock of a Restricted  Subsidiary  all  indebtedness  of such
Restricted  Subsidiary to the Company or any other Restricted Subsidiary is paid
in full,  and all  guarantees  or other  support  undertakings  provided  by the
Company or other Restricted  Subsidiaries in respect of such disposed Restricted
Subsidiary are discharged, concurrently with the sale in question, provided that
then  existing  Performance  Guarantees or guaranties in respect of surety bonds
with respect to such a Restricted  Subsidiary  need not be so  discharged  as to
jobs which commenced prior to the completion of such sale. Concurrently with the
sale of all of the capital stock of a Restricted  Subsidiary  permitted  hereby,
the Agent is authorized  and directed to release any Guarantee  provided by such
Restricted  Subsidiary  and any Lien on the stock or  assets of such  Restricted
Subsidiary  and such entity shall no longer  constitute a Restricted  Subsidiary
hereunder.  Except  as set forth in the Side  Letter,  the  Borrowers  shall not
permit any Restricted  Subsidiary to enter into any contract or agreement  after
the date hereof  prohibiting  or restricting  such  Restricted  Subsidiary  from
paying  dividends or making loans and advances to the Company except in the case
of a  Restricted  Subsidiary  formed or  acquired  to be a captive  insurer or a
captive surety.

     Section 7.16. Dividends and Certain Other Restricted Payments.  The Company
will not during any fiscal year (a) declare or pay any  dividends on or make any
other  distributions  in  respect  of any class or series of its  capital  stock
(except for dividends  payable  solely in its capital  stock) or (b) directly or
indirectly  purchase,  redeem or otherwise  acquire or retire any of its capital
stock or any options or warrants  therefor  except out of the net  proceeds of a
substantially  concurrent  issuance  and sale of  capital  stock or  options  or
warrants therefor  (collectively,  "Restricted Payments") if after giving effect
thereto (i) the aggregate  amount  expended for all such purposes  subsequent to
the date hereof would exceed the difference  between (x)  $50,000,000  plus (but
not minus in the case of a deficit) 50% of Net Income for the period (taken as a
single  accounting  period) from the date hereof to the last day of the calendar
quarter most recently  completed prior to the Restricted Payment in question and
(y) any portion of the amount  computed  pursuant to clause (x) hereof which was
used to justify a  transaction  under  Section  7.13  pursuant  to clause  (iii)
thereof  and (ii) no  Default or Event of Default  shall  have  occurred  and be
continuing.

     Section  7.17.  ERISA.  The  Borrowers  shall,  and shall cause each of the
Restricted  Subsidiaries  to,  promptly pay and  discharge all  obligations  and
liabilities  arising under ERISA of a character  which if unpaid or  unperformed
might result in the  imposition of a Lien against any of their  Properties.  The
Borrowers  shall,  and  shall  cause  each of the  Restricted  Subsidiaries  to,
promptly  notify  the  Agent  and  each  Lender  of (i)  the  occurrence  of any
reportable event (as defined in ERISA) with respect to any employee benefit plan
subject to Title IV of ERISA  (other than a  multiemployer  plan)  sponsored  or
contributed to by either of the Borrowers or any member of the Controlled  Group
(a  "Plan")  with  respect  to  which  the PBGC has  neither  waived  the 30 day
reporting  requirement  nor  issued  a  public  announcement  that  the  penalty
applicable  to a failure to report  will not apply,  (ii)  receipt of any notice
from the PBGC of its intention to seek termination of any Plan or appointment of
a trustee  therefor,  (iii) its intention to terminate any Plan or withdraw from
any  multiemployer  plan if such  termination or withdrawal  could reasonably be
expected to have a Material Adverse Effect, and (iv) the occurrence of any other
event with  respect  to any Plan which  would  result in the  incurrence  by the
Borrowers or any of their  Restricted  Subsidiaries  of any material  liability,
fine or penalty,  or any material  increase in the  contingent  liability of the
Borrowers  or  any  of  the   Restricted   Subsidiaries   with  respect  to  any
post-retirement  Welfare Plan benefit which could reasonably be expected to have
a Material Adverse Effect.

     Section 7.18. Compliance with Laws. The Company shall, and shall cause each
of its Restricted  Subsidiaries to, comply in all respects with the requirements
of all foreign (whether national,  supra-national or otherwise), federal, state,
provincial, and local laws, rules, regulations, ordinances and orders applicable
to or pertaining to their Properties or business operations, non-compliance with
which could have a Material Adverse Effect or could result in a Lien upon any of
their Property material to the Company and the Restricted  Subsidiaries taken as
a whole.

     Section 7.19. Burdensome Contracts With Affiliates.  The Company shall not,
nor  shall it permit  any of its  Restricted  Subsidiaries  to,  enter  into any
contract,  agreement or business  arrangement with any of its Affiliates  (other
than  with or among  Restricted  Subsidiaries  and the  Company)  on  terms  and
conditions  which  are less  favorable  to the  Company  or any such  Restricted
Subsidiary than would be usual and customary in similar contracts, agreements or
business arrangements between Persons not affiliated with each other.

     Section 7.20.  No Changes in Fiscal Year.  The Company shall not change its
fiscal year from its present  basis  without  the prior  written  consent of the
Required Lenders.

     Section 7.21. Formation of Subsidiaries. The Company will not, and will not
permit any Restricted  Subsidiary  to, form or acquire any Subsidiary  except in
connection with acquisitions  permitted by Section 7.12 hereof and the formation
of new  subsidiaries  if in any such case and in either such  instance the newly
formed or acquired  Subsidiary  shall, if the Required Lenders so request and to
the extent required by this Agreement, execute and deliver a Guarantee and grant
Liens on its assets of the priority  required by Section 4.1 hereof (and provide
the Agent with such documentation  therefore and such supporting  documentation,
including opinions of counsel,  as it may reasonably  request).  Each Subsidiary
acquired or formed  pursuant  hereto shall  constitute  a Restricted  Subsidiary
unless the Required Lenders otherwise agree in writing.

     Section 7.22. Change in the Nature of Business.  The Company shall not, and
shall not permit any of the Restricted  Subsidiaries  to, engage in any business
or activity if as a result the general nature of the business of the Company and
the Restricted  Subsidiaries  would be changed in any material  respect from the
general  nature of the  business  engaged in by the Company  and the  Restricted
Subsidiaries on the date of this Agreement.

     Section 7.23. Use of Proceeds.  The Borrowers shall use the proceeds of the
initial  Credit  Utilization  hereunder  to the  extent  necessary  to repay all
indebtedness,   obligations   (other  than  L/C   Obligations)  and  liabilities
outstanding under the Existing Agreement and all Credit Utilizations  thereafter
for the purposes set forth in, or otherwise permitted by, Section 5.4 hereof.

     without notice or demand from the Agent,  either (i) immediately pay to the

     provided in subsection (b) below or (ii) provide a back-up letter of credit
     for the benefit of the Agent in a stated amount equal to the full amount of
     all Letters of Credit then  outstanding  which  letter of credit shall give
     the Agent the unconditional  right to make drawings thereunder upon receipt
     of a drawing  request  under any Letter of Credit and  otherwise be in form

     immediately make each such payment or provide such back-up letter of credit
     and  acknowledging and agreeing the Agent would not have an adequate remedy
     at law for failure of the  Borrowers  to honor any such demand and that the
     Agent shall have the right to require the Borrowers to specifically perform

     of Credit.

          (b) All amounts prepaid  pursuant to subsection (a) above or paid over

     therein, and any substitutions for such account, any certificate of deposit
     or other instrument evidencing any of the foregoing and all proceeds of and
     earnings on any of the foregoing being collectively  called the "Collateral
     Account") as security for, and for  application by the Agent (to the extent
     available) (i) with respect to amounts  prepaid  pursuant to subsection (a)
     above, to the  reimbursement of any payment under any Letter of Credit then
     or thereafter  made by the Agent,  and to the payment of the unpaid balance
     of any Loans and all other Obligations or (ii) with respect to amounts paid
     over to the  Agent  pursuant  to  Section  3.5(b)  hereof,  as set forth in

     subject to the exclusive  dominion and control of the Agent for the benefit
     of the Agent, the Lenders and the Applicable  Issuer. If and when requested
     by the  Borrower,  the Agent  shall  invest  funds  held in the  Collateral
     Account  from time to time in direct  obligations  of, or  obligations  the
     principal of and interest on which are  unconditionally  guaranteed by, the
     United  States of America  with a  remaining  maturity of one year or less,
     provided that the Agent is irrevocably  authorized to sell investments held
     in the Collateral  Account when and as required to make payments out of the
     Collateral  Account  for  application  to  amounts  due and owing  from any
     Borrower to the  Applicable  Issuer,  the Agent or the  Lenders;  provided,
     however,  that if (i) the  Borrowers  shall  have made  payment of all such
     obligations  referred  to in  subsection  (a) above or Section  3.5(b),  as
     applicable,  (ii) all relevant  preference  or other  disgorgement  periods
     relating  to the  receipt  of such  payments  have  passed,  and (iii) with
     respect to amounts  prepaid  pursuant  to  subsection  (a) above  only,  no
     Letters  of  Credit,   Commitments,   Loans  or  other  Obligations  remain
     outstanding  hereunder (other than unasserted  indemnity  obligations which
     survive  the  termination  hereof),  then the Agent  shall  release  to the
     Company any remaining amounts held in the Collateral Account.

assumed by the Required  Lenders and (i) the Borrowers and  Guarantors  shall be
directed to make all payments due each Lender hereunder  directly to such Lender
and (ii) the  Agent's  rights  in the  Collateral  Documents  shall be  assigned
without  representation,  recourse or warranty to the Lenders as their interests
may appear.

reserve all of the rights,  powers and duties hereunder and under the other Loan
Documents  as any Lender may have and may  exercise the same as though they were

and in all of such  documents  shall,  unless the  context  otherwise  expressly
indicates,  include  the Agent and  Issuers in their  individual  capacities  as
Lender.

     Section  10.3.  Standard of Care.  The Lenders  acknowledge  that they have
received and approved  copies of the Loan  Documents and such other  information
and documents  concerning the  transactions  contemplated and financed hereby as
they have requested to receive and/or review.  The Agent and the Issuers make no
representations  or  warranties  of any kind or  character  to the Lenders  with
respect to the validity, enforceability,  genuineness,  perfection, value, worth
or  collectibility  hereof or of the Revolving  Credit Notes or any of the other
Obligations  or of any of the other Loan  Documents or of the Liens provided for

event be liable for any clerical  errors or errors in judgment,  inadvertence or
oversight, or for action taken or omitted to be taken by it or them hereunder or
under the other Loan Documents or in connection  herewith or therewith except to
the extent the same is solely a result of its or their own gross  negligence  or
willful misconduct as determined by a final,  non-appealable judgment of a court
of competent  jurisdiction.  The Agent and the Issuers  shall incur no liability
under or in respect of this Agreement or the other Loan Documents by acting upon
any notice, certificate, warranty, instruction or statement (oral or written) of
anyone  (including anyone in good faith believed by them to be authorized to act
on  behalf  of  any  Borrower),   unless  they  have  actual  knowledge  of  the
untruthfulness  of same.  The Agent and the  Issuers  may  execute  any of their
duties hereunder by or through  employees,  agents,  and  attorneys-in-fact  and
shall not be answerable to the Lenders for the default or misconduct of any such
agents or  attorneys-in-fact  selected with  reasonable  care. The Agent and the
Issuers shall be entitled to advice of counsel concerning all matters pertaining
to the agencies  hereby created and their duties  hereunder,  and shall incur no
liability  to anyone and be fully  protected  in acting  upon the advice of such
counsel.  The Agent and the Issuers  shall be entitled to assume that no Default
or Event of Default  exists  unless  notified to the  contrary by a Lender.  The
Agent  and the  Issuers  shall in all  events  be fully  protected  in acting or
failing to act in accord with the instructions of the Required Lenders. Upon the
occurrence  of an Event of Default  hereunder,  the Agent shall take such action
with  respect  to  the  enforcement  of the  Liens  on the  Collateral  and  the
preservation  and  protection  thereof  as it shall be  directed  to take by the
Required  Lenders  but unless  and until the  Required  Lenders  have given such
direction  the Agent shall take or refrain  from taking such actions as it deems
appropriate  and in the best  interest  of all  Lenders.  The Agent shall in all
cases be fully  justified in failing or refusing to act  hereunder and under the
other Loan Documents  unless it shall be indemnified to its  satisfaction by the
Lenders  against any and all  liability and expense which may be incurred by the
Agent by reason of taking or continuing  to take any such action.  The Agent may
treat the owner of any Revolving Credit Note as the holder thereof until written
notice of transfer  shall have been filed with the Agent signed by such owner in
form  satisfactory  to  the  Agent.   Each  Lender   acknowledges  that  it  has
independently and without reliance on the Agent, the Issuers or any other Lender
and based  upon  such  information,  investigations  and  inquiries  as it deems
appropriate  made its own credit  analysis and decision to extend  credit to the
Borrowers. It shall be the responsibility of each Lender to keep itself informed
as to the creditworthiness of the Borrowers and the Guarantors and the Agent and
Issuers shall have no liability to any Lender with respect thereto.

them hereby or thereby,  to the extent that they are not promptly reimbursed for

respective Commitments.

therefor), harmless from and against any liabilities,  losses, costs or expenses
suffered or incurred by them  hereunder or under the other Loan  Documents or in
connection with the transactions  contemplated hereby or thereby,  regardless of
when asserted or arising,  except to the extent they are promptly reimbursed for
the same by the Borrowers or out of the Collateral and except to the extent that
any event giving rise to a claim was caused  solely by the gross  negligence  or
willful  misconduct  of the party seeking to be  indemnified  as determined by a
final, non-appealable judgment of a court of competent jurisdiction.

     Section 10.6. Quebec Matters.  For the purposes of any Collateral Documents
to be granted by any one or more of the  Borrowers  in favor of the Agent to the
extent  that  such  Collateral  Documents  will be  governed  by the laws of the

attorney for all present and future Lenders.  Any future Lender under the Credit
Agreement,  by the execution of an Assignment  Agreement in accordance  with the
provisions of Section 11.17,  shall be deemed to have  irrevocably  ratified the
power of attorney granted to the Agent in the immediately  proceeding  sentence.

respecting the Special Powers of Legal Persons  (Quebec),  the Agent may, as the

of the Borrowers to the Agent pursuant to the laws of the Province of Quebec.

exclusively of such  Affiliate's  right to share in payments and collections out
of the  Collateral  and the  Guarantees  as more fully set forth in Section  3.7
hereof.  In connection with any such  distribution of payments and  collections,

     and subject to Section  11.1(b)  hereof,  each payment by each Borrower and
     each Guarantor  under this  Agreement or the other Loan Documents  shall be
     made without  withholding  for or on account of any present or future taxes
     (other  than  overall  net  income  taxes  (but  not  withholdings)  on the
     recipient  imposed  by a  jurisdiction  where  it is  domiciled  or  has an
     established  place of business)  imposed by or within the  jurisdiction  in
     which such Borrower or such Guarantor is domiciled,  any jurisdiction  from
     which such Borrower or such Guarantor makes any payment,  or (in each case)
     any political  subdivision or taxing authority  thereof or therein.  If any
     such withholding is so required,  the Borrower or relevant  Guarantor shall
     make  the   withholding,   pay  the  amount  withheld  to  the  appropriate
     governmental  authority before penalties attach thereto or interest accrues
     thereon and  forthwith  pay such  additional  amount as may be necessary to
     ensure that the net amount  actually  received by each Lender and the Agent
     free and  clear of such  taxes  (including  such  taxes on such  additional
     amount) is equal to the amount  which that Lender or the Agent (as the case
     may be) would have  received  had such  withholding  not been made.  If the
     Agent or any Lender pays any amount in respect of any such taxes, penalties
     or interest (including without limitation,  for the avoidance of doubt, any
     taxes,  penalties  or  interest  attributable  to  any  amounts  reimbursed
     pursuant to the provisions  hereof) the Borrowers shall reimburse the Agent
     or that  Lender for that  payment on demand in the  currency  in which such
     payment was made.  If the  Borrowers or any  Guarantor  pay any such taxes,
     penalties or interest,  they shall deliver official tax receipts evidencing
     that  payment or certified  copies  thereof to the Lender or Agent on whose
     account  such  withholding  was made  (with a copy to the  Agent if not the
     recipient of the original) on or before the thirtieth day after payment. If
     any Lender or the Agent determines it has received or been granted a credit
     against or relief or  remission  for,  or  repayment  of, any taxes paid or
     payable  by it  because of any taxes,  penalties  or  interest  paid by the
     Borrowers or any Guarantor and evidenced by such a tax receipt, such Lender
     or  Agent  shall,  to the  extent  it can do so  without  prejudice  to the
     retention of the amount of such credit, relief, remission or repayment, pay
     to the  Borrowers  or such  Guarantor  as  applicable,  such amount as such
     Lender or Agent reasonably  determines is attributable to such deduction or
     withholding  and which will leave such Lender or Agent (after such payment)
     in no better or worse  position than it would have been in if the Borrowers
     or Guarantors had not been required to make such deduction or  withholding.
     Nothing in this Agreement shall interfere with the right of each Lender and
     the Agent to arrange its tax  affairs in whatever  manner it thinks fit nor
     oblige any Lender or the Agent to disclose any information  relating to its
     tax affairs or any computations in connection with such taxes.

          (b) U.S. Withholding Tax Exemptions.  Each Lender that is not a United
     States person (as such term is defined in Section  7701(a)(30) of the Code)
     shall submit to the Borrowers and the Agent on or before the earlier of the
     date the initial Borrowing is made hereunder and thirty (30) days after the
     date hereof,  two duly  completed  and signed  copies of either Form W8-BEN
     (relating  to such Lender and  entitling  it to a complete  exemption  from
     withholding  under the Code on all amounts to be  received by such  Lender,
     including fees,  pursuant to the Loan Documents and the Revolving Loans) or
     Form  W8-ECI  (relating  to all  amounts  to be  received  by such  Lender,
     including fees,  pursuant to the Loan Documents and the Revolving Loans) of
     the United States  Internal  Revenue  Service.  Thereafter and from time to
     time,  each  Lender  shall  submit  to the  Borrowers  and the  Agent  such
     additional  duly  completed  and signed  copies of one or the other of such
     Forms (or such successor forms as shall be adopted from time to time by the
     relevant  United States taxing  authorities) as may be (i) requested by the
     Company in a written notice,  directly or through the Agent, to such Lender
     and (ii) required  under  then-current  United States law or regulations to
     avoid or reduce United States  withholding  taxes on payments in respect of
     all amounts to be received by such Lender,  including fees, pursuant to the
     Loan Documents or the Revolving Loans. Notwithstanding the foregoing, (i) a
     Lender  which  becomes a Lender after the date hereof shall not be required
     to submit a Form W8-BEN or Form W8-ECI  until the date it becomes a Lender;
     and (ii) a Lender shall have no obligations to provide either such Form (or
     successor  form)  subsequent to the date it becomes a Lender if such Lender
     is excused from doing so pursuant to Section 11.1(c).

          (c) Inability of Lender to Submit Forms. If any Lender determines,  as
     a result of any change in applicable law,  regulation or treaty,  or in any
     official application or interpretation thereof, that it is unable to submit
     to the  Borrowers  or Agent any form or  certificate  that  such  Lender is
     obligated to submit  pursuant to  subsection  (b) of this Section  11.1. or
     that such  Lender  is  required  to  withdraw  or  cancel  any such form or
     certificate  previously submitted or any such form or certificate otherwise
     becomes  ineffective or inaccurate,  such Lender shall promptly  notify the
     Company and the Agent of such fact and the Lender  shall to that extent not
     be obligated to provide any such form or  certificate  and will be entitled
     to withdraw or cancel any affected form or certificate,  as applicable.  If
     any Lender can avoid the effect of any such  change in law,  regulation  or
     treaty or in the application or interpretation thereof, whether by changing
     its lending office or otherwise,  it undertakes to do so if the same can be
     accomplished  without  disadvantage  to it.  If some,  but not all,  of the
     Lenders are affected by a change of the type described herein,  such Lender
     agrees that it will at the request of the Company assign its Obligations to
     another  Lender under and pursuant to the  conditions  set forth in Section
     11.17 hereof.

     Section 11.2.  Holidays.  If any payment of principal or interest on any of
the Revolving  Credit Notes or any fees shall fall due on a Saturday,  Sunday or
on another day which is a legal  holiday  for lenders in the State of  Illinois,
(i) interest at the rates such Notes bear for the period prior to maturity shall
continue  to accrue on such  principal  from the stated due date  thereof to and
including the next succeeding Business Day and (ii) such principal, interest and
fees shall be payable on such succeeding Business Day.

     Section 11.3. No Waiver,  Cumulative  Remedies.  No delay or failure on the
part of the Agent,  any  Issuer or any  Lender or on the part of the Agent,  any
Issuer or any holder of any of the  Obligations  in the exercise of any power or
right shall operate as a waiver  thereof,  nor as an acquiescence in any default
nor shall any  single or partial  exercise  of any power or right  preclude  any
other or further  exercise of any other power or right.  The rights and remedies
hereunder of the Agent,  the  Issuers,  Lenders and of the holders of any of the
Obligations  are  cumulative  to, and not  exclusive  of, any rights or remedies
which any of them would otherwise have.

     Section 11.4. Amendments. Any provision of this Agreement or the other Loan
Documents may be amended or waived if, but only if, such  amendment or waiver is
in writing and is signed by (a) the Borrowers, (b) the Required Lenders, and (c)
if the  rights or duties of the Agent or an Issuer  are  affected  thereby,  the
Agent or such Issuer, as applicable; provided that:

               (i) no  amendment  or waiver  pursuant to this Section 11.4 shall
          (A) increase any  Commitment of any Lender without the consent of such
          Lender  or (B)  reduce  the  amount  of or  postpone  the date for any
          scheduled  payment of any  principal  of or interest on any Loan or of
          any  Reimbursement  Obligation or of any fee payable hereunder without
          the consent of the Lender to which such  payment is owing or which has
          committed  to make  such Loan or  Letter  of  Credit  (or  participate
          therein) hereunder; and

               (ii) no amendment or waiver  pursuant to this Section 11.4 shall,
          unless signed by each Lender,  increase the aggregate  Commitments  of
          the Lenders,  change the  definitions of Termination  Date or Required
          Lenders,  change the  provisions  of this  Section  11.4,  release any
          material  guarantor or any substantial part of the Collateral  (except
          as otherwise provided for in the Loan Documents), or affect the number
          of Lenders  required to take any action  hereunder  or under any other
          Loan Document;

     Section 11.5. Costs and Expenses.  The Borrowers agree to pay on demand all
reasonable  costs and expenses of the Agent in connection with the  negotiation,
preparation,  execution,  delivery,  recording  or filing or release of the Loan
Documents or in connection with any consents  hereunder or thereunder or waivers
or amendments  hereto or thereto or assignments  pursuant hereto,  including the
reasonable fees and expenses of counsel for the Agent with respect to all of the
foregoing,  and all recording,  filing, insurance or other fees, costs and taxes
incident to  perfecting a Lien upon the  collateral  security for the  Revolving
Credit Notes and the other  Obligations,  and all reasonable  costs and expenses
(including  reasonable  attorneys' fees) incurred by the Agent, the Issuers, the
Lenders or any other holders of the  Obligations in connection  with any Default
or Event of Default or in connection with the enforcement of the Loan Documents,
and all reasonable  costs, fees and taxes of the types enumerated above incurred
in  supplementing  (and  recording  or  filing  supplements  to) the  Collateral
Documents in connection with assignments contemplated by Section 11.17 hereof if
counsel to the Agent  believes such  supplements to be appropriate or desirable.
The Borrowers  agree to indemnify and save the Lenders,  the Issuers,  the Agent
and any security  trustee for the Agent or the Lenders harmless from any and all
liabilities,  losses, costs and expenses incurred by the Lenders, the Issuers or
the Agent in connection with any action,  suit or proceeding brought against the
Agent or the  Issuers,  any  security  trustee or any Lender by any Person which
arises  out of the  transactions  contemplated  or  financed  by any of the Loan
Documents or out of any action or inaction by the Agent, any security trustee or
any  Lender  thereunder,  except  for such  thereof  as is  caused  by the gross
negligence or willful  misconduct of the party  seeking to be  indemnified.  The
provisions  of this  Section  11.5 and the  protective  provisions  of Section 2
hereof shall survive payment of the Obligations.

     Section  11.6.  Stamp  Taxes.  The  Borrowers  agree that they will pay any
documentary,  stamp or similar taxes payable in respect to this Agreement or any
other Loan Document,  including  interest and  penalties,  in the event any such
taxes are assessed,  irrespective of when such assessment is made and whether or
not any credit to it is then in use or available.

     Section   11.7.   Survival  of   Representations   and   Indemnities.   All
representations and warranties made herein or in any of the other Loan Documents
or in certificates  given pursuant hereto or thereto shall survive the execution
and delivery of this Agreement and the other Loan Documents,  and shall continue
in full force and effect with  respect to the date as of which they were made as
long as any credit is in use or available  hereunder.  All indemnities and other
provisions  relative to  reimbursement to the Agent, the Issuers and the Lenders
of amounts  sufficient  to protect  the yield of the Agent,  the Issuers and the
Lenders  with  respect to the Loans and  Letters of Credit,  shall  survive  the
termination of this Agreement and the payment of the Obligations.

     Section 11.8.  Construction.  The parties hereto acknowledge and agree that
this  Agreement  shall not be construed  more favorably in favor of one than the
other based upon which party  drafted the same, it being  acknowledged  that all
parties hereto  contributed  substantially to the negotiation and preparation of
this Agreement.

     Section 11.9. Addresses for Notices. Unless specifically provided otherwise
hereunder,  all communications provided for herein shall be in writing and shall
be deemed to have been given or made when served  personally or three days after
being deposited in the United States mail addressed, if to any Borrower, in each
case to such  Borrower  in care of the Company at 301  Merritt  Seven  Corporate
Park, Norwalk,  Connecticut 06851,  Attention:  Chairman of the Board, and if to
the Lenders at their  addresses as shown on the signature pages hereof or on any
Assignment  Agreement,  or at such other  address as shall be  designated by any
party hereto in a written  notice  given to each party  pursuant to this Section
11.9.

     Section  11.10.   Obligations  Several.  The  obligations  of  the  Lenders
hereunder are several and not joint.  Nothing contained in this Agreement and no
action taken by the Lenders  pursuant  hereto shall be deemed to constitute  the
Lenders a partnership, association, joint venture or other entity.

     Section  11.11.  Headings.  Article  and  Section  headings  used  in  this
Agreement  are for  convenience  of  reference  only  and are not a part of this
Agreement for any other purpose.

     Section 11.12. Severability of Provisions.  Any provision of this Agreement
which is unenforceable in any jurisdiction  shall, as to such  jurisdiction,  be
ineffective  to the extent of such  unenforceability  without  invalidating  the
remaining  provisions hereof or affecting the validity or enforceability of such
provision in any other jurisdiction. All rights, remedies and powers provided in
this Agreement and other Loan Documents may be exercised only to the extent that
the exercise  thereof does not violate any  applicable  mandatory  provisions of
law, and all the  provisions  of this  Agreement  and other Loan  Documents  are
intended to be subject to all applicable  mandatory  provisions of law which may
be controlling  and to be limited to the extent  necessary so that they will not
render this Agreement or other Loan Documents invalid or
unenforceable.

     Section 11.13.  Counterparts.  This Agreement may be executed in any number
of counterparts,  and by different parties hereto on separate counterparts,  and
all such  counterparts  taken together shall be deemed to constitute one and the
same instrument.

     Section 11.14.  Binding  Nature and Governing Law. This Agreement  shall be
binding upon the Borrowers and their successors and assigns,  and shall inure to
the  benefit of the Lenders and the  benefit of their  successors  and  assigns,
including any  subsequent  holder of an interest of the Revolving  Credit Notes.
This  Agreement  and the  rights  and  duties  of the  parties  hereto  shall be
construed  and  determined  in  accordance  with,  and shall be  governed by the
internal laws of the State of Illinois without regard to principles of conflicts
of law. No Borrower may assign its rights or obligations  hereunder  without the
written consent of all of the Lenders.

     Section 11.15.  Entire  Understanding.  This  Agreement,  together with the
other Loan  Documents  and any  agreements  between  the  Company  and the Agent
concerning fees, constitute the entire understanding of the parties with respect
to the subject matter hereof and any prior agreements,  whether written or oral,
with respect thereto are superseded hereby.

     Section 11.16.  Participations.  Any Lender may grant participations in its
extensions  of  credit   hereunder  to  any  other   financial   institution  (a
"Participant") provided that (i) no Participant shall thereby acquire any direct
rights under this  Agreement,  (ii) no Lender shall agree with a Participant not
to exercise any of its rights hereunder  without the consent of such Participant
except for rights  which  under the terms  hereof may only be  exercised  by all
Lenders,  (iii) no sale of a participation  in extensions of credit shall in any
manner  relieve the selling  Lender of its  obligations  hereunder  and (iv) the
Borrowers  shall not be  responsible  for the costs  incurred  by any  Lender in
connection with such participations.

     Section 11.17.  Assignment  Agreements.  Each Lender may, from time to time
upon at least five Business Days' notice to the Agent, assign to other financial
institutions  all or part of its rights  and  obligations  under this  Agreement
(including without limitation the indebtedness evidenced by the Revolving Credit
Notes  then  owned  by  such  assigning  Lender,  together  with  an  equivalent
proportion of its obligation to make Revolving  Loans and participate in Letters
of Credit hereunder)  pursuant to an Assignment  Agreement;  provided,  however,
that (i) unless the Company  (provided that the consent of the Company shall not
be required after the  occurrence  and during the  continuance of any Default or
Event of Default) and the Agent otherwise consents each such assignment shall be
of a constant,  and not a varying,  percentage of the assigning  Lender's rights
and  obligations  under this Agreement and the  assignment  shall cover the same
percentage of such Lender's Commitment,  Revolving Loans,  Revolving Credit Note
and interests in Letters of Credit;  (ii) unless the Agent  otherwise  consents,
the  assigning  Lender  shall  assign all of its  Commitment,  Revolving  Loans,
Revolving  Credit Note and  interests in the Letters of Credit or the  aggregate
amount thereof being assigned pursuant to each such assignment (determined as of
the  effective  date of the relevant  Assignment  Agreement)  shall be an amount
which  shall in no event  be less  than  $10,000,000  and  shall be an  integral
multiple of $1,000,000;  (iii) the Agent and the Company (which is acting on its
own behalf and  pursuant  to Section  1.6 hereof on behalf of the  Borrowers  as
well) must each consent  (provided  that the consent of the Company shall not be
required after the occurrence and during the continuance of any Default or Event
of Default), which consent shall not be unreasonably withheld (provided that the
Company  may  withhold  its  consent to an  assignment  by the Agent in its sole
discretion  if after giving  effect  thereto the Agent would have a  Commitment,
computed  prior to  giving  effect  to any  reductions  or  terminations  of the
Commitments,  of less than $25,000,000) and shall be evidenced by execution of a
counterpart of the relevant  Assignment  Agreement in the space provided thereon
for  such  acceptance,  to each  such  assignment  to a party  which  was not an
original  signatory of this  Agreement and (v) the assigning  Lender must pay to
the Agent a processing  and  recordation  fee of $3,500  except that no such fee
shall be payable in the case of an assignment to an Affiliate of such  assigning
Lender. Upon the execution of each Assignment  Agreement by the assigning Lender
thereunder,  the assignee lender thereunder, the Company (provided that any such
Assignment   Agreement   entered  into  after  the  occurrence  and  during  the
continuation  of any Default or Event of Default shall not require the Company's
execution) and the Agent and payment to such  assigning  Lender by such assignee
lender  of the  purchase  price  for  the  portion  of the  indebtedness  of the
Borrowers being acquired by it, (i) such assignee lender shall thereupon  become
a "Lender" for all purposes of this  Agreement  with a Commitment  in the amount
set forth in such  Assignment  Agreement  and with all the  rights,  powers  and
obligations  afforded a Lender hereunder,  (ii) such assigning Lender shall have
no further  liability for funding the portion of its Commitment  assumed by such
other Lender and (iii) the address for notices to such assignee  Lender shall be
as specified in the Assignment  Agreement executed by it.  Concurrently with the
execution and delivery of such  Assignment  Agreement,  the Borrowers shall each
execute and deliver  Revolving  Credit Notes to the assignee  Lender,  (all such
Revolving Credit Notes to constitute  "Revolving  Credit Notes" for all purposes
of the Loan  Documents) and if the  assignment is of the full  Commitment of the
assigning  Lender,  the assignor  Lender shall  thereupon  return the  Revolving
Credit Notes  theretofore  issued to it to the Company marked  "canceled" and if
such  assignment is not an assignment of the full  Commitment of such  assignor,
the  assignor  shall  return  its  Revolving  Credit  Note  and new  appropriate
Revolving  Credit  Notes shall be issued to the  assignee  and  assignor.  If an
assignor is an Issuer its rights and  obligations  as Issuer shall be unaffected
by any  assignment.  Notwithstanding  the  foregoing,  (i) any Lender may at any
time,  without the consent of the Company or the Agent,  assign all or a portion
of its rights under the Loan  Documents to any of its  Affiliates  or any Lender
which is an  original  signatory  hereto,  and (ii) any  Lender may at any time,
without  the  consent of the  Company  or the Agent,  assign and pledge all or a
portion  of its  rights  under the Loan  Documents  to a Federal  Reserve  Bank;
provided,  however,  that no such assignment  under clause (ii) of this sentence
shall release the transferor Lender from its obligations hereunder or cause such
Federal Reserve Bank to become a "Lender" hereunder.

     Section  11.18.  Terms of  Collateral  Documents  not  Superseded.  Nothing
contained  herein  shall be deemed or  construed  to permit any act or  omission
which is prohibited by the terms of any Collateral  Document,  the covenants and
agreements contained herein being in addition to and not in substitution for the
covenants and agreements contained in the Collateral Documents.

       Section 11.19. PERSONAL JURISDICTION and Jury Trial Waivers.

          (a) EXCLUSIVE JURISDICTION.  EXCEPT AS PROVIDED IN SUBSECTION (b), THE
     AGENT,  THE LENDERS AND THE  BORROWERS  agree THAT ALL DISPUTES  AMONG THEM
     ARISING  OUT  OF,  CONNECTED  WITH,   RELATED  TO,  OR  INCIDENTAL  TO  THE
     RELATIONSHIP  ESTABLISHED AMONG THEM IN CONNECTION WITH THIS AGREEMENT, AND
     WHETHER ARISING IN CONTRACT, TORT, EQUITY, OR OTHERWISE,  SHALL BE resolved
     ONLY BY (AND EACH OF THEM FOR THE BENEFIT OF THE OTHERS HEREBY  IRREVOCABLY
     SUBMITS TO THE JURISDICTION OF) THE state OR FEDERAL COURTS LOCATED IN COOK
     COUNTY,  ILLINOIS,  BUT EACH OF THE AGENT,  THE LENDERS  AND THE  BORROWERS
     ACKNOWLEDGE  THAT ANY APPEALS  FROM THOSE  COURTS MAY HAVE TO BE HEARD BY A
     COURT LOCATED OUTSIDE OF COOK COUNTY,  ILLINOIS. THE BORROWERS WAIVE IN ALL
     DISPUTES  ANY  OBJECTION  THAT THEY MAY HAVE TO THE  LOCATION  OF THE COURT
     CONSIDERING THE DISPUTE.

          (b) OTHER JURISDICTIONS.  THE BORROWERS AGREE THAT THE AGENT, AND EACH
     OF THE LENDERS  SHALL HAVE THE RIGHT TO PROCEED  AGAINST THE  BORROWERS  OR
     THEIR PROPERTY  ("PROPERTY")  IN A COURT IN ANY LOCATION OR JURISDICTION TO
     ENABLE  THE AGENT OR ANY LENDER TO  REALIZE  ON  PROPERTY,  OR TO ENFORCE A
     JUDGMENT OR OTHER  COURT ORDER  ENTERED IN FAVOR OF THE AGENT OR ANY LENDER
     AND,  WITHOUT  PREJUDICE TO THE GENERALITY OF THE FOREGOING,  EACH BORROWER
     AGREES  THAT  THE  AGENT  OR ANY  LENDER  SHALL  BE  ENTITLED  TO  COMMENCE
     PROCEEDINGS (WHETHER FOR THE PURPOSE OF OBTAINING OR ENFORCING ANY ORDER OR
     JUDGMENT OR OTHERWISE  HOWSOEVER) IN THE COURTS OF THE JURISDICTIONS  WHERE
     SUCH BORROWER OR ANY OF ITS PROPERTY IS LOCATED.

          (c) Jury Trial  Waiver.  The  Borrowers,  the Agent,  and each  Lender
     hereby  irrevocably  waives any and all right to trial by jury in any legal
     proceeding  arising  out  of or  relating  to  any  Loan  Document  or  the
     transactions contemplated thereby.

          Section  11.20.  Currency.  Each  reference in this  Agreement to U.S.
     Dollars or to an Alternative  Currency (the "relevant  currency") is of the
     essence.  To the fullest  extent  permitted by law, the  obligation of each
     Borrower in respect of any amount due in the relevant  currency  under this
     Agreement or the L/C Documents  shall,  notwithstanding  any payment in any
     other currency (whether pursuant to a judgment or otherwise), be discharged
     only to the extent of the amount in the relevant  currency  that the Agent,
     Issuer or Lender  entitled to receive such payment may, in accordance  with
     normal  banking  procedures,  purchase  with  the sum  paid  in such  other
     currency  (after any premium and costs of  exchange)  on the  Business  Day
     immediately following the day on which such party receives such payment. If
     the amount in the relevant currency so purchased for any reason falls short
     of the amount originally due in the relevant currency,  the Borrowers shall
     pay such additional amounts, in the relevant currency,  as may be necessary
     to  compensate  for the  shortfall.  Any  obligations  of the Borrowers not
     discharged  by such  payment  shall,  to the fullest  extent  permitted  by
     applicable law, be due as a separate and independent  obligation and, until
     discharged as provided herein, shall continue in full force and effect.

          Section 11.21. Currency Equivalence.  If for the purposes of obtaining
     judgment  in any  court  it is  necessary  to  convert  a sum due  from any
     Borrower on the Obligations in the currency  expressed to be payable herein
     or in an  Application or under the Revolving  Credit Notes (the  "specified
     currency")  into  another  currency,  the  parties  agree  that the rate of
     exchange  used shall be that at which in  accordance  with  normal  banking
     procedures the Agent could purchase the specified  currency with such other
     currency on the  Business  Day  preceding  that on which final  judgment is
     given.  The  obligation  of each Borrower in respect of any such sum due to
     the  Agent,   any  Issuer  or  any   Lender  on  the   Obligations   shall,
     notwithstanding  any  judgment  in a  currency  other  than  the  specified
     currency,  be  discharged  only  to the  extent  that on the  Business  Day
     following  receipt by the Agent, such Issuer or such Lender, as applicable,
     of any sum adjudged to be so due in such other  currency,  the Agent,  such
     Issuers or such  Lender,  as  applicable,  may in  accordance  with  normal
     banking  procedures   purchase  the  specified  currency  with  such  other
     currency. If the amount of the specified currency so purchased is less than
     the sum  originally  due to the Agent,  such  Issuers or such Lender in the
     specified  currency,  the Borrowers  agree,  as a separate  obligation  and
     notwithstanding any such judgment,  to indemnify the Agent, such Issuers or
     such Lender,  as the case may be,  against such loss,  and if the amount of
     the specified  currency so purchased  exceeds the amount  originally due to
     the Agent, such Issuer or such Lender in the specified currency, the Agent,
     such Issuer or such Lender, as the case may be, agrees to remit such excess
     to the Borrowers.

     Section 11.22. Change in Currency.

          (a) If more than one  currency or  currency  unit are at the same time
     recognized  by the central  bank of any  country as the lawful  currency of
     that  country,  (i)  any  reference  in any  Loan  Documents  to,  and  any
     obligations  arising  under any Loan  Documents  in, the  currency  of that
     country  shall be  translated  into,  and paid in, the currency or currency
     unit designated by the Agent, after consultation with the Borrowers and the
     Lenders and (ii) any  translation  from one  currency  or currency  unit to
     another shall be at the official rate of exchange recognized by the central
     bank of that country for the  conversion  of that currency or currency unit
     into the other, rounded up or down by the Agent, acting reasonably.

     Documents  will, to the extent the Agent (acting  reasonably)  specifies is
     necessary, be amended to comply with any generally accepted conventions and
     market practice in any relevant  interbank  market and otherwise to reflect
     the change in currency and, if there is no generally accepted convention or
     market practice, or the Agent considers,  in its absolute discretion,  that
     there is no  generally  accepted  convention  or market  practice,  in such
     manner and to such extent as the Agent specifies. The Agent will notify the
     other parties to the relevant Loan Documents of any such  amendment,  which
     shall be binding on all the parties to that Loan Document.

     the Agent, pay to the Agent for the account of any Lender the amount of any
     costs or increased  costs  incurred  by, or of any  reduction in any amount
     payable to or in the  effective  return on its capital  pursuant  to, or of
     interest or other return foregone by, such Lender or any holding company of
     such Lender as a result of any change in the currency of a country.

the  contrary,  if at any time the interest  rate  applicable to any Loan to any
Borrower, together with all fees, charges and other amounts which are treated as
interest on such Loan under applicable law (collectively,  the "Charges"), shall
exceed the maximum lawful rate permitted by applicable law (the "Maximum  Rate")
which may be contracted for, charged,  taken, received or reserved by any one or
more of the Lenders  holding such Loan in accordance  with  applicable  law, the
rate of interest  payable in respect of such Loan  hereunder,  together with all
Charges payable in respect thereof, shall be limited to the Maximum Rate and, to
the extent  lawful,  the  interest and Charges that would have been payable with
respect to such Loan but were not payable as a result of the  operation  of this
Section  11.23 shall be cumulated  and the interest and Charges  payable to such
Lender or Lenders in respect of other  Loans shall be  increased  (but not above
the Maximum Rate therefor) until such cumulated  amount,  together with interest
thereon at the rate set out herein, to the date of repayment, shall be have been
received by such Lender or Lenders.

     Accepted  and Agreed to at  Chicago,  Illinois  as of the day and year last
above written.

     Each of the Lenders  hereby agrees with each other Lender that if it should
receive or obtain any payment (whether by voluntary payment, by realization upon
collateral,   by  the  exercise  of  rights  of  setoff  or  banker's  lien,  by
counterclaim  or cross  action,  or by the  enforcement  of any rights under the
Amended  and  Restated  Credit  Agreement,  the  Revolving  Credit  Notes or the
Collateral  Documents or otherwise) in respect of the Obligations,  in a greater
amount than such Lender  would have  received  had such payment been made to the
Agent and been  distributed  among the  Lenders as  contemplated  by Section 3.7
hereof,  then in that event the Lender receiving such  disproportionate  payment
shall  purchase for cash without  recourse from the other Lenders an interest in
the  Obligations  owed to such  Lenders  in such  amount  as shall  result  in a
distribution of such payment as contemplated by Section 3.7 hereof. In the event
any payment made to a Lender and shared with the other  Lenders  pursuant to the
provisions  hereof is ever recovered from such Lender,  the Lenders  receiving a
portion of such payment  hereunder  shall  restore the same to the payor Lender,
with interest to the extent  payable by the payor.  In the event any amount paid
to an Issuer under the  Applications  shall ever be recovered  from such Issuer,
each Lender shall  reimburse such Issuer for its pro rata share of the amount so
recovered with interest to the extent payable by the Issuer.

Harris N.A., as Agent
111 West Monroe Street
Chicago, IL  60690 and
Lenders from time to time party to
the Amended and Restated
Credit Agreement hereinafter identified

Ladies and Gentlemen:

     I am Executive Vice President and General  Counsel of EMCOR Group,  Inc., a
Delaware  corporation (the "Company"),  and have acted as counsel to the Company
and the  corporations,  limited  liability  companies  and limited  partnerships
listed on Exhibit A hereto (the "Domestic Guarantors", and collectively with the
Company, the "Organizations") in connection with the Amended and Restated Credit
Agreement dated as of October 14, 2005 (the "Credit Agreement") by and among the
Company and certain of its  subsidiaries  and Harris N.A.,  individually  and as
Agent, and the Lenders which are or become parties thereto,  pursuant to which a
revolving  credit  facility  is  being  made  available  by you to the  Company,
Comstock  Canada  Ltd.,  a Canadian  corporation,  and EMCOR Group (UK) plc.,  a

     This opinion is being  delivered  pursuant to Section  6.2(m) of the Credit

respective meanings assigned to such terms in the Credit Agreement.

     In connection with this opinion, I have reviewed the Credit Agreement;  the

Guaranty  Agreement dated as of October 14, 2005 made by the Guarantors (as such
term is defined in such  Guaranty  Agreement),  including  the Company and other

Agreement  dated as of October 14, 2005 by and among the  Pledgors (as such term
is defined in such Pledge  Agreement),  including the Company and other entities
substantially owned,  directly or indirectly by the Company, and Harris (as such
term is defined in such Pledge  Agreement),  as Agent, and the form of Amendment
to Pledge Agreement included as Schedule B to such Pledge Agreement and the form
of Assumption and Supplemental  Pledge Agreement  included as Schedule C to such
Pledge Agreement;  the form of Amended and Restated Security  Agreement dated as
of October  14,  2005 by and among the  Debtors (as such term is defined in such
Security  Agreement),  including  the Company and other  entities  substantially
owned,  directly  or  indirectly,  by the  Company,  and Harris (as such term is
defined in such Security  Agreement),  as Agent,  and the form of Assumption and
Supplemental  Security  Agreement  included  as  Schedule  G  to  such  Security
Agreement (collectively, the "Loan Documents").

          I have also reviewed and am familiar with:

               (i) a copy of the certificate of incorporation  (or other similar
          organization  document) of each  Organization  which is a corporation,
          certified by the Secretary,  Clerk,  Assistant  Secretary or Assistant
          clerk of such Organization;

               (ii) a copy of the  certificate  of formation  (or other  similar

          Domestic Guarantor.

     I also have examined such other corporate,  limited  liability  company and
limited   partnership   documents   and  records  and  such  other   agreements,
certificates,  opinions, instruments, papers, statutes and authorities, and have
made such  examinations  of law, as I have deemed  necessary  as a basis for the
opinions below.

     In such  examinations,  I have assumed the  genuineness  of all  signatures
(other than those of representatives of the Organizations), the completeness and
authenticity  of all records and all documents  submitted to me as originals and
the conformity to original  documents of the documents supplied to me as copies.
As to various  questions of fact material to such  opinions,  I have relied upon
representations  and  warranties of each of the  Organizations  contained in the
Loan Documents and upon statements and certificates of the officers,  Members or
a Manager  of the  Organizations  or of  officers  of the  general  partners  of
Organizations  that are limited  partnerships  and of other  parties to the Loan
Documents and of public officials, and upon public records. I have not conducted
a search of or otherwise examined the records of any court.

     For purposes of the opinions hereinafter expressed, I have assumed that (a)
each party to any Loan Document (other than the  Organizations) has the power to
enter into and perform all of its  obligations  thereunder,  (b) each such party
(other than the  Organizations) has taken all necessary actions to authorize the
due  execution,  delivery and  performance  of such Loan Document by it, and (c)
each such Loan Document is the legal,  valid and binding obligation of each such
party (other than the Organizations) thereto.

     The  opinions  set forth in numbered  paragraph 3 below with respect to the
legality,  validity,  binding effect and enforceability of any Loan Document are
subject  to  the  effect  of  bankruptcy,   insolvency,  moratorium,  fraudulent
conveyance and similar laws relating to or affecting creditors' rights generally
and court decisions with respect thereto,  and I express no opinion with respect
to  the  application  of  equitable  principles  to  any  Loan  Document  in any
proceeding, whether at law or in equity.

     I express no opinion as to the  enforceability  of  provisions  of the Loan
Documents which: (a) restrict access to legal or equitable remedies; (b) purport
to waive or affect any rights to  notices;  (c) contain a covenant by a party to
take  actions  the  taking  of which is  discretionary  with or  subject  to the
approval of another party or which are otherwise  subject to  contingencies  the
fulfillment of which is not within the control of the party so covenanting;  (d)
purport to limit the  Agent's  obligations  to exercise  reasonable  care in the
custody and preservation of collateral in accordance with the Uniform Commercial
Code of the State of New  York;  (e)  purport  to  exculpate  a party  from,  or
indemnify a party against, its own negligence or failure to act in good faith or
in accordance with standards of commercial reasonableness;  (f) purport to allow
the Agent to establish  evidentiary standards for suit or proceedings to enforce
such  Loan  Documents;  (g)  purport  to allow  the  Agent to set off and  apply
deposits of any Organization to its obligations under the Loan Documents without
prior notice having been given to any Organization,  or as to the enforceability
of any  waiver  by any  Organization  of  demand  or of  rights  to  set-off  or
counterclaim;  (h) relate to delay,  election  or  omission  of  enforcement  of
remedies;  (i) relate to severability;  or (j) purport to constitute  waivers of
rights of subrogation, reimbursement,  contribution, exoneration or indemnity by
any Organization.  I also point out that legal and equitable  principles require
good faith and fair  dealing by the Agent and may  require the Agent to exercise
its  rights  and  remedies  under the Loan  Documents  in a  reasonable  manner,
including,  but not limited to, consideration by the Agent of the materiality of
any breach by any  Organization  and of the  consequences  of such breach to the
Agent. Furthermore,  certain other provisions as to rights, remedies,  covenants
and  limitations  contained  in the  Loan  Documents  are  subject  to  legal or
equitable  principles  relating  to the strict or specific  enforcement  of such
rights, remedies,  covenants and limitations.  However, subject to the effect of
bankruptcy,  insolvency,  moratorium,  fraudulent  conveyance  and similar  laws
relating to or affecting  creditors'  rights  generally and court decisions with
respect thereto,  the limitations  referred to in this paragraph and/or in other
parts of this opinion,  do not, in my opinion,  make the remedies and procedures
which  will be  afforded  to the Agent  inadequate  for the  realization  of the
substantive benefits purported to be provided under the Loan Documents.

     I also point out that the enforceability of the  above-referenced  Security
Agreement and the security interests created thereby may be subject to rights of
account  debtors  and any  claims  or  defenses  of  such  persons  against  any
Organization.  Moreover, in the case of receivables that are due from the United
States or any state thereof or any  department of the United States or any state
thereof,  the right to  collect  upon such  receivables  may be  limited  by the
Assignment of Claims Act, 31 U.S.C.A.  ss. 3727 (1989) and any applicable  state
law relating to the assignment of claims against such State.

     I express no opinion  with  respect to the right,  title or interest of any
Organization  in or to any property,  the existence,  location or description of
any Collateral (as such term is defined in the Loan Documents),  or the priority
or  perfection of any security  interest or other Lien in any of the  Collateral
(as such term is defined in the Loan Documents) or any other Lien referred to in
the Loan Documents.

     When  reference is made in this opinion to "knowledge" or to what is "known
to me", it means my actual  knowledge and in this regard it is noted that I have
not made any  special  review,  investigation  or  inquiry  in  connection  with
rendering the opinion with respect to the matters so qualified.

     I am admitted to practice law in the State of New York and I do not purport
to be expert on, or to express any opinion herein concerning, any law other than
the laws of the State of New York,  the  federal  laws of the  United  States of
America  and the  General  Corporation  Law of the  State of  Delaware.  For the
purposes  of this  opinion,  I have  assumed  that  the  laws of the  States  of
Illinois,  and of the  state of  incorporation  or  organization  of each of the
Organizations  not  incorporated  or  organized  in  Delaware  or New York,  are
identical  to the laws of the  State of New  York.  For the  purpose  of the due
certification  of  status  in the  first  sentence  of my  opinion  in  numbered
paragraph 1 below, I have relied solely upon certificates of public officials of
the states of  organization  of each of the  Organizations.  For  purposes of my
opinion  expressed  in the second  sentence  of  numbered  paragraph  1 below in
respect of due qualification and good standing as a foreign  organization,  I am
relying   solely  on  the   representations   and  warranties  of  each  of  the
Organizations contained in the Loan Documents.

     Based upon and subject to the foregoing, I am of the opinion that:

          1.  Each of the  Organizations  which is a  corporation  is a  validly
     existing corporation in good standing under the laws of its jurisdiction of
     incorporation  and has the  corporate  power and  authority to transact the
     business  in  which  it is  engaged  as  now  conducted,  and  each  of the
     Organizations which is a limited liability company or a limited partnership
     is a legally existing  limited  liability  company or limited  partnership,
     respectively,  in good  standing  or in  existence  under  the  laws of its
     jurisdiction  of  organization  and has the power and authority to transact
     the  business  in  which  it is  engaged  and  now  conducted.  Each of the
     Organizations  is  duly  qualified  and  in  good  standing  as  a  foreign
     corporation or limited liability company, as the case may be, in all of the
     states in which,  to my knowledge,  failure to be so qualified would have a
     Material Adverse Effect.

          2. The Company has the corporate power to borrow and apply for Letters
     of Credit from you. Each  Domestic  Guarantor  has the  corporate,  limited
     liability company, limited partnership,  or other power to guarantee all of
     the indebtedness,  obligations and liabilities of the Company and the other
     Borrowers to you pursuant to the Credit  Agreement.  Each  Organization has
     the corporate,  limited liability company,  limited  partnership,  or other
     power to mortgage,  pledge,  assign and  otherwise  encumber its assets and
     properties as  collateral  security for such  borrowings,  letter of credit
     liabilities  and  guarantees,  to execute and  deliver  the Loan  Documents
     executed by it and to which it is a party and to observe and perform all of
     the terms and provisions of such Loan Documents. The execution and delivery
     of the Loan Documents  executed by each of the Organizations  does not, nor
     will the  observance  and  performance  of any of the terms and  provisions
     thereof,  violate any law or the certificate of incorporation,  certificate
     of formation,  by-laws,  limited  liability  company  agreement,  operating
     agreement, or limited partnership agreement (or other similar documents) of
     any such  Organization  or, to my  knowledge,  any  covenant,  indenture or
     agreement to which such Organization is a party.

          3. The Loan  Documents  executed by each  Organization  have been duly
     authorized by all necessary corporate,  limited liability company,  limited
     partnership,  or other  action,  have been  executed  and  delivered by the
     proper  officers  or  other   representatives   of  such  Organization  and
     constitute valid and binding agreements of such  Organization,  enforceable
     against it in accordance with the respective terms of such Loan Documents.

          4.   Except  as  may  be  required  in  order  to  perfect  the  Liens
     contemplated  by the Loan  Documents,  no  order,  authorization,  consent,
     license  or  exemption  of, or filing or  registration  with,  any court or
     governmental department,  agency, instrumentality or regulatory body of the
     United States of America or the State of New York is or will be required in
     connection with the lawful  execution and delivery of the Loan Documents by
     each   Organization   party  thereto  or  the   performance  by  each  such
     Organization of any of the terms of the Loan Documents.

          5. To my knowledge, after due inquiry, except as disclosed on Schedule
     5.9 of the  Credit  Agreement  or the Side  Letter  or in the  notes to the
     financial  statements  of the  Company as at and for the fiscal  year ended
     December  31,  2005 or in the  Company's  Form 10-Q for the fiscal  quarter
     ended June 30, 2005, there is no action, suit,  proceeding or investigation
     at law or in  equity  before  or by any court or  public  body  pending  or
     threatened  against  any  Organization  or any of its assets or  properties
     which, if adversely determined, could result in a Material Adverse Effect.

     This opinion letter is furnished solely for your benefit in connection with
matters relating to the Loan Documents and may not be used or relied upon by any
other person or for any other purpose without my prior written consent.


                                                      Very truly yours,


                                                      Sheldon I. Cammaker
