Item 1.01. Entry into a Material Definitive Agreement.

(a)	On September 19, 2007, EMCOR Group, Inc. (the “Company”) entered into a Term Loan Agreement (the “Loan Agreement”) dated as of September 19, 2007 with Bank of Montreal, as Administrative Agent, and the several financial institutions listed on the signature pages thereof (collectively, the “Term Loan Lenders”).
	The Loan Agreement provides for a term loan to the Company of $300,000,000. If the Company so desires it may identify one or more additional lenders (which may include existing Term Loan Lenders) willing to participate, or increase their participation, in the Loan Agreement, and thereby increase the Company’s borrowings under the Loan Agreement by up to an additional $150,000,000, provided that Bank of Montreal, as Administrative Agent, consents thereto, such consent not to be unreasonably withheld. The $300,000,000 loan proceeds were used to pay a portion of the consideration for the acquisition of FR X Ohmstede Acquisition Co., a Delaware corporation (“Ohmstede”), and costs and expenses incident thereto.
	The Loan Agreement contains financial covenants, representations and warranties and events of default. The Company is to make principal payments on the term loan under the Loan Agreement in installments on the last day of March, June, September and December of each year, commencing with the calendar quarter ending March 31, 2008 in the amount of $750,000, together with interest on the then outstanding principal amount. A final payment comprised of all principal and interest not sooner paid is due on October 17, 2010. The Loan Agreement is secured by substantially all of the assets of the Company, substantially all of the assets of substantially all of its U.S. subsidiaries pursuant to the terms of a Second Amended and Restated Security Agreement dated as of September 19, 2007 (the “Security Agreement”) among the Company, substantially all of its U.S. subsidiaries, and Harris N.A. (“Harris”), as Agent, and the terms of a Second Amended and Restated Pledge Agreement dated as of September 19, 2007 (the “Pledge Agreement”) among the Company, substantially all of its U.S. subsidiaries and Harris, as Agent. The Company’s obligations under the Loan Agreement are guaranteed by substantially all of its U.S. subsidiaries pursuant to the terms of a Guaranty Agreement dated as of September 19, 2007 (the “Guaranty”).
	The collateral securing the term loan also secures the obligations of the Company and its subsidiaries under an Amended and Restated Credit Agreement effective October 17, 2005 with Harris N.A., as Agent, and certain other lender parties (the “Revolving Credit Lenders”) thereto (the “Credit Agreement”) providing for a revolving credit facility under which the Company, Comstock Canada, Ltd., a wholly-owned subsidiary of the Company, and EMCOR Group (UK) plc., a wholly-owned subsidiary of the Company, may borrow up to an aggregate of $375,000,000.
	Harris as Agent under the Security Agreement and Pledge Agreement holds the liens and security interests granted pursuant to the Security Agreement and Pledge Agreement for the benefit of the Term Loan Lenders and the Revolving Credit Lenders.

	The Loan Agreement, Security Agreement, Pledge Agreement and Guaranty are attached hereto as Exhibits 4.1(a), 4.1(b), 4.1(c), and 4.1(d), respectively.
	The foregoing descriptions of the Loan Agreement, Security Agreement, Pledge Agreement and Guaranty do not purport to be complete and are qualified in their entirety by reference to the full text of the Loan Agreement, Security Agreement, Pledge Agreement and Guaranty, respectively, attached hereto as Exhibits 4.1(a), 4.1(b), 4.1(c), and 4.1(d), respectively.
(b)	Effective September 19, 2007, the Company, its wholly-owned subsidiaries Comstock Canada Ltd. and EMCOR Group (UK) plc., and the other parties to the Credit Agreement entered into a First Amendment to the Credit Agreement (the “Amendment”). Pursuant to the terms of the Amendment, the Credit Agreement was amended in several respects which, among others, permitted the Company to enter into and borrow under the Term Loan Agreement and acquire Ohmstede.
	The Amendment is attached hereto as Exhibit 4.1(e).
	The foregoing description of the Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Amendment, attached hereto as Exhibit 4.1(e).

Item 2.03. Creation of a Direct Financial Obligation or an Obligation under an Off Balance Sheet Arrangement of a Registrant.

EMCOR GROUP, INC.

TERM LOAN AGREEMENT

          This Term Loan Agreement is entered into as of September 19, 2007, by and among EMCOR GROUP, INC., a Delaware corporation (the “Borrower”), the several financial institutions from time to time party to this Agreement, as Lenders, and BANK OF MONTREAL, a Canadian chartered bank acting through its Chicago branch, as Administrative Agent as provided herein. All capitalized terms used herein without definition shall have the same meanings herein as such terms are defined in Section 5.1 hereof.

PRELIMINARY STATEMENT

          The Borrower has requested, and the Lenders have agreed to extend, certain credit facilities on the terms and conditions of this Agreement.

          NOW, THEREFORE, in consideration of the mutual agreements contained herein, and other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1. THE CREDIT FACILITIES.

          Section 1.1. Term Loan Commitments. Subject to the terms and conditions hereof, each Lender, by its acceptance hereof, severally agrees to make a loan (individually a “Term Loan” and collectively for all the Lenders the “Term Loans”) in U.S. Dollars to the Borrower in the amount of such Lender’s Commitment. The Term Loans shall be advanced in a single Borrowing on the Closing Date and shall be made ratably by the Lenders in proportion to their respective Percentages, at which time the Commitments shall expire. As provided in Section 1.3(a) hereof, the Borrower may elect that the Term Loans be outstanding as Base Rate Loans or Eurodollar Loans. No amount repaid or prepaid on any Term Loan may be borrowed again.

          Section 1.2. Minimum Borrowing Amounts; Maximum Eurodollar Loans. Each Borrowing of Base Rate Loans shall be in an amount not less than $100,000. Each Borrowing of Eurodollar Loans continued or converted shall be in an amount equal to $1,000,000 or such greater amount which is an integral multiple of $500,000. Without the Administrative Agent’s consent, there shall not be more than Eight (8) Borrowings of Eurodollar Loans outstanding hereunder at any one time.

          Section 1.3. Manner of Borrowing Loans and Designating Applicable Interest Rates. (a) Notice to the Administrative Agent. Subject to the terms and conditions hereof, the Borrower may from time to time elect to change or continue the type of interest rate borne by each Borrowing or, subject to the minimum amount requirement for each outstanding Borrowing set forth in Section 1.2 hereof, a portion thereof, as follows: (i) if such Borrowing is of Eurodollar Loans, on the last day of the Interest Period applicable thereto, the Borrower may continue part or all of such Borrowing as Eurodollar Loans or convert part or all of such Borrowing into Base

Rate Loans or (ii) if such Borrowing is of Base Rate Loans, on any Business Day, the Borrower may convert all or part of such Borrowing into Eurodollar Loans for an Interest Period or Interest Periods specified by the Borrower. The Borrower shall give all such notices requesting the continuation or conversion of a Borrowing to the Administrative Agent by telephone, telecopy, or other telecommunication device acceptable to the Administrative Agent (which notice shall be irrevocable once given and, if by telephone, shall be promptly confirmed in writing), substantially in the form attached hereto as Exhibit F (Notice of Continuation/Conversion), as applicable, or in such other form acceptable to the Administrative Agent. Notice of the continuation of a Borrowing of Eurodollar Loans for an additional Interest Period or of the conversion of part or all of a Borrowing of Base Rate Loans into Eurodollar Loans must be given by no later than 10:00 a.m. (Chicago time) at least three (3) Business Days before the date of the requested continuation or conversion. All such notices concerning the continuation or conversion of a Borrowing shall specify the date of the requested continuation or conversion of a Borrowing (which shall be a Business Day), the amount of the requested Borrowing to be continued or converted, the type of Term Loans to comprise such continued or converted Borrowing and, if such Borrowing is to be comprised of Eurodollar Loans, the Interest Period applicable thereto. Upon notice to the Borrower by the Administrative Agent or the Required Lenders, no Borrowing of Eurodollar Loans shall be continued or created by conversion if any Default or Event of Default then exists. The Borrower agrees that the Administrative Agent may rely on any such telephonic, telecopy or other telecommunication notice given by any person the Administrative Agent in good faith believes is an Authorized Representative without the necessity of independent investigation, and in the event any such notice by telephone conflicts with any written confirmation such telephonic notice shall govern if the Administrative Agent has acted in reliance thereon.

          (b) Notice to the Lenders. The Administrative Agent shall give prompt telephonic, telecopy or other telecommunication notice to each Lender of any notice from the Borrower received pursuant to Section 1.3(a) above and, if such notice requests the Lenders to make Eurodollar Loans, the Administrative Agent shall give notice to the Borrower and each Lender by like means of the interest rate applicable thereto promptly after the Administrative Agent has made such determination.

          (c) Borrower’s Failure to Notify. If the Borrower fails to give notice pursuant to Section 1.3(a) above of the continuation or conversion of any outstanding principal amount of a Borrowing of Eurodollar Loans before the last day of its then current Interest Period within the period required by Section 1.3(a) and such Borrowing is not repaid, such Borrowing shall automatically be converted into an equal Borrowing of Base Rate Loans.

          (d) Disbursement of Loans. On the Closing Date, each Lender shall make available its Percentage of the Term Loan in funds immediately available at the principal office of the Administrative Agent in Chicago, Illinois (or at such other location as the Administrative Agent shall designate). The Administrative Agent shall make the proceeds of the Term Loan available to the Borrower at the Administrative Agent’s principal office in Chicago, Illinois (or at such other location as the Administrative Agent shall designate), by depositing or wire transferring such proceeds to the credit of the Borrower’s Designated Disbursement Account or as the Borrower and the Administrative Agent may otherwise agree.

-2-

          (e) Administrative Agent Reliance on Lender Funding. Unless the Administrative Agent shall have been notified by a Lender prior to (or, in the case of a Borrowing of Base Rate Loans, by 1:00 p.m. (Chicago time) on) the date on which such Lender is scheduled to make payment to the Administrative Agent of the proceeds of the Term Loan (which notice shall be effective upon receipt) that such Lender does not intend to make such payment, the Administrative Agent may assume that such Lender has made such payment when due and the Administrative Agent may in reliance upon such assumption (but shall not be required to) make available to the Borrower the proceeds of the Term Loan to be made by such Lender and, if any Lender has not in fact made such payment to the Administrative Agent, such Lender shall, on demand, pay to the Administrative Agent the amount made available to the 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 the Borrower and ending on (but excluding) the date such Lender pays such amount to the Administrative Agent at a rate per annum equal to: (i) from the date the related advance was made by the Administrative Agent to the date two (2) Business Days after payment by such 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 Lender to the date such payment is made by such Lender, the Base Rate in effect for each such day. If such amount is not received from such Lender by the Administrative Agent immediately upon demand, the Borrower will, on demand, repay to the Administrative Agent the proceeds of the Term Loan attributable to such Lender with interest thereon at a rate per annum equal to the interest rate applicable to the relevant Loan, but without such payment being considered a payment or prepayment of a Loan under Section 2.2 hereof so that the Borrower will have no liability under such Section with respect to such payment.

          Section 1.4. 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 Base Rate Loan, the sum of 2.0% plus the Applicable Margin plus the Base Rate from time to time in effect; and

          (b) for any Eurodollar Loan, 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 Base Rate Loans plus the Base Rate from time to time in effect.

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

          Section 1.5. Maturity of Loans. The Borrower shall make principal payments on the Term Loans in installments on the last day of each March, June, September, and December in

-3-

each year, commencing with the calendar quarter ending March 31, 2008, with the amount of each such principal installment to equal the amount set forth in Column B below shown opposite of the relevant due date as set forth in Column A below:

COLUMN A	COLUMN B
PAYMENT DATE	SCHEDULED PRINCIPAL PAYMENT ON TERM LOANS

06/30/08	$750,000

12/31/08	$750,000

03/31/10	$750,000
06/30/10	$750,000
09/30/10	$750,000

, it being agreed that a final payment comprised of all principal and interest not sooner paid on the Term Loans shall be due and payable on October 17, 2010, the final maturity thereof (the “Maturity Date”). Each such principal payment shall be applied to the Lenders holding the Term Loans pro rata based upon their Percentages.

          Section 1.6. Evidence of Indebtedness. (a) Each Lender shall maintain in accordance with its usual practice an account or accounts evidencing the indebtedness of the Borrower to such Lender resulting from each Loan made by such Lender from time to time, including the amounts of principal and interest payable and paid to such Lender from time to time hereunder.

          (b) The Administrative Agent shall also maintain accounts in which it will record (i) the amount of each Loan made hereunder, the type thereof and the Interest Period with respect thereto, (ii) the amount of any principal or interest due and payable or to become due and payable from the Borrower to each Lender hereunder and (iii) the amount of any sum received by the Administrative Agent hereunder from the Borrower and each Lender’s share thereof.

          (c) The entries maintained in the accounts maintained pursuant to paragraphs (a) and (b) above shall be prima facie evidence of the existence and amounts of the Obligations therein recorded; provided, however, that the failure of the Administrative Agent or any Lender to maintain such accounts or any error therein shall not in any manner affect the obligation of the Borrower to repay the Obligations in accordance with their terms.

-4-

          (d) Any Lender may request that its Loans be evidenced by a promissory note or notes in the form of Exhibit A (a “Term Note”). In such event, the Borrower shall prepare, execute and deliver to such Lender a Term Note payable to such Lender or its registered assigns in the amount of such Lender’s Commitment. Thereafter, the Loans evidenced by such Note or Notes and interest thereon shall at all times (including after any assignment pursuant to Section 11.17) be represented by one or more Notes payable to the order of the payee named therein or any assignee pursuant to Section 11.17, except to the extent that any such Lender or assignee subsequently returns any such Note for cancellation and requests that such Loans once again be evidenced as described in subsections (a) and (b) above.

          Section 1.7. Increase in Commitments. The Borrower may, on any Business Day prior to the Maturity Date, increase the aggregate outstanding principal amount of the Term Loans by delivering a Commitment Amount Increase Request substantially in the form attached hereto as Exhibit G or in such other form reasonably acceptable to the Administrative Agent at least five (5) Business Days prior to the desired effective date of such increase (the “Commitment Amount Increase”) identifying any additional Lender(s) (or additional Term Loans for existing Lender(s)) and the amount of its Term Loans (or additional amount of its Term Loans); provided, however, that (i) any increase shall be in an amount not less than $25,000,000 and in the aggregate for all such increases not greater than $150,000,000, (ii) no Default or Event of Default shall have occurred and be continuing at the time of the request or the effective date of the Commitment Amount Increase, (iii) all representations and warranties contained in Section 5 hereof shall be true and correct in all material respects at the time of such request (except to the extent such representation or warranty is expressly limited to an earlier date, in which case such representation and warranty shall be true and correct in all material respects as of such date) and on the effective date of such Commitment Amount Increase, (iv) prior to approaching new lenders, the Borrower shall offer to Lenders the option to increase their respective outstanding Term Loans, (v) after giving effect to the increase in outstanding Term Loans, the Borrower is in compliance with Sections 7.6, 7.7 and 7.8 hereof, on a pro forma basis, and (vi) the Administrative Agent shall consent in writing (which consent shall not be unreasonably withheld or delayed) to any increase pursuant to this Section 1.6. The effective date of the Commitment Amount Increase shall be agreed upon by the Borrower and the Administrative Agent. Upon the effectiveness thereof, the new Lender(s) (or, if applicable, existing Lender(s)) shall advance Loans in an amount sufficient such that after giving effect to its advance each Lender shall have outstanding its applicable Percentage of Loans. It shall be a condition to such effectiveness that if any Eurodollar Loans are outstanding on the date of such effectiveness, such Eurodollar Loans shall be deemed to be prepaid on such date and the Borrower shall pay any amounts owing to the Lenders pursuant to Section 2.2 hereof. The Borrower agrees to pay the reasonable out-of-pocket expenses of the Administrative Agent relating to any Commitment Amount Increase. Notwithstanding anything herein to the contrary, no Lender shall have any obligation to advance additional Term Loans, and each Lender may at its option, unconditionally and without cause, decline to advance additional Term Loans. Any additional Term Loan advanced under this Section 1.7 shall be “Term Loans” for all purposes of this Agreement.

Each Base Rate Loan made or maintained by a Lender shall bear interest (computed on the basis of a year of 365 or 366 days, as the case may be, and the actual days elapsed) on the unpaid principal amount thereof from the date such Loan is advanced, or created by conversion from a Eurodollar Loan, until maturity (whether by acceleration or otherwise) at a rate per annum equal to the sum of the Applicable Margin plus the Base Rate from time to time in effect, payable by the Borrower on each Interest Payment Date and at maturity (whether by acceleration or otherwise).

          “Base Rate” means for any day the greater of: (i) the rate of interest announced or otherwise established by the Administrative Agent from time to time as its prime commercial rate, or its equivalent, for U.S. Dollar loans to borrowers located in the United States as in effect on such day, with any change in the Base Rate resulting from a change in said prime commercial rate to be effective as of the date of the relevant change in said prime commercial rate (it being acknowledged and agreed that such rate may not be the Administrative Agent’s best or lowest rate) and (ii) the sum of (x) the rate determined by the Administrative Agent to be the average (rounded upward, if necessary, to the next higher 1/100 of 1%) of the rates per annum quoted to the Administrative Agent at approximately 10:00 a.m. (Chicago time) (or as soon thereafter as is practicable) on such day (or, if such day is not a Business Day, on the immediately preceding Business Day) by two or more Federal funds brokers selected by the Administrative Agent for sale to the Administrative Agent at face value of Federal funds in the secondary market in an amount equal or comparable to the principal amount for which such rate is being determined, plus (y) 1/2 of 1%.

          (b) Eurodollar Loans. Each Eurodollar Loan made or maintained by a Lender shall bear interest during each Interest Period it is outstanding (computed on the basis of a year of 360 days and actual days elapsed) on the unpaid principal amount thereof from the date such Loan is advanced or continued, or created by conversion from a Base Rate Loan, until maturity (whether by acceleration or otherwise) at a rate per annum equal to the sum of the Applicable Margin plus the Adjusted LIBOR applicable for such Interest Period, payable by the Borrower on each Interest Payment Date and at maturity (whether by acceleration or otherwise).

          “Adjusted LIBOR” means, for any Borrowing of Eurodollar Loans, a rate per annum determined in accordance with the following formula:

		LIBOR
Adjusted LIBOR	=
		1 - Eurodollar Reserve Percentage

          “Eurodollar Reserve Percentage” means, for any Borrowing of Eurodollar Loans, the daily average for the applicable Interest Period of the maximum rate, expressed as a decimal, at which reserves (including, without limitation, any supplemental, marginal, and emergency reserves) are imposed during such Interest Period by the Board of Governors of the Federal Reserve System (or any successor) on “eurocurrency liabilities”, as defined in such Board’s Regulation D (or in respect of any other category of liabilities that includes deposits by reference to which the interest rate on Eurodollar Loans is determined or any category of extensions of

-6-

credit or other assets that include loans by non-United States offices of any Lender to United States residents), subject to any amendments of such reserve requirement by such Board or its successor, taking into account any transitional adjustments thereto. For purposes of this definition, the Eurodollar Loans shall be deemed to be “eurocurrency liabilities” as defined in Regulation D without benefit or credit for any prorations, exemptions or offsets under Regulation D.

          “LIBOR” means, for an Interest Period for a Borrowing of Eurodollar Loans, (a) the LIBOR Index Rate for such Interest Period, if such rate is available, and (b) if the LIBOR Index Rate cannot be determined, the arithmetic average of the rates of interest per annum (rounded upwards, if necessary, to the nearest 1/100 of 1%) at which deposits in U.S. Dollars in immediately available funds are offered to the Administrative Agent at 11:00 a.m. (London, England time) two (2) Business Days before the beginning of such Interest Period by three (3) or more major banks in the interbank eurodollar market selected by the Administrative Agent for delivery on the first day of and for a period equal to such Interest Period and in an amount equal or comparable to the principal amount of the Eurodollar Loan scheduled to be made as part of such Borrowing.

          “LIBOR Index Rate” means, for any Interest Period, the rate per annum (rounded upwards, if necessary, to the next higher one hundred-thousandth of a percentage point) for deposits in U.S. Dollars for a period equal to such Interest Period, which appears on the LIBOR01 Page as of 11:00 a.m. (London, England time) on the day 2 Business Days before the commencement of such Interest Period.

          “LIBOR01 Page” means the display designated as “Reuters Screen LIBOR01 Page” (or such other page as may replace the LIBOR01 Page on that service or such other service as may be nominated by the British Bankers’ Association as the information vendor for the purpose of displaying British Bankers’ Association Interest Settlement Rates for U.S. Dollar deposits).

          (c) Rate Determinations. The Administrative Agent shall determine each interest rate applicable to the Loans hereunder, and its determination thereof shall be conclusive and binding except in the case of manifest error.

          Section 2.2. 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 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 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 the Borrower to borrow or refund a Eurodollar Loan on the date specified in a notice given pursuant to this Agreement,

-7-

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

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

then, upon the demand of such Lender, the 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 Borrower, with a copy to the Administrative 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 2.3. 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 Eurodollar Loans, such Lender shall promptly give notice thereof to the Borrower and such Lender’s obligations to make or maintain Eurodollar Loans under this Agreement shall terminate until it is no longer unlawful for such Lender to make or maintain such Loans. The 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 Borrower may then elect to borrow the principal amount of the affected Loans from such Lender by means of Base Rate Loans which Loans shall not be made ratably by the Lenders but only from such affected Lender.

          Section 2.4. Unavailability. If prior to the commencement of any Interest Period for any Borrowing of Eurodollar Loans:

          (a) the Administrative Agent determines that deposits in U.S. Dollars (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 Administrative Agent that (i) LIBOR as determined by the Administrative Agent will not adequately and fairly reflect the cost to such Lenders of funding their Eurodollar Loans for such Interest Period or (ii) that the making or funding of Eurodollar Loans has become impracticable,

then and in any such event the Administrative Agent shall not less than two days prior to the commencement of such Interest Period, give notice thereof to the Borrower and the Lenders, whereupon until the Administrative Agent notifies the Borrower that the circumstances giving rise to such suspension no longer exist, the obligations of the Lenders to make Eurodollar Loans shall be suspended.

-8-

          Section 2.5. 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 Term Notes, or its obligation to make Loans, 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, or any other amounts due under this Agreement in respect of its Eurodollar Loans or its obligation to make Eurodollar Loans (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 Loans, its Term Notes or any of its obligation to make Loans;

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 Term Loan, 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 Term 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 Administrative Agent), the Borrower 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 2.5 shall notify the Borrower and the Administrative Agent of the circumstances that entitle the Lender to such compensation pursuant to this Section 2.5 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 2.5 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 2.6. 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

-9-

(each a “Lending Office”) for each type of Term 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 Borrower and the Administrative Agent (but such funds shall in any event be made available to the Borrower at the office of the Administrative Agent as herein provided for), provided that the Borrower 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 Borrower consented in writing to such change.

          Section 2.7. 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 Term 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 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 2.8. 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 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 Borrower 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 2.8 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 2.9. Substitution of Lenders. In the event (a) the Borrower receives a claim from any Lender for compensation under Section 2.5 or 11.1 hereof, (b) the Borrower receives notice from any Lender of any illegality pursuant to Section 2.3 hereof, (c) any Lender is in default in any material respect with respect to its obligations under the Loan Documents, or (d) a Lender fails to consent to an amendment or waiver requested under Section 11.4 hereof at a time when the Required Lenders have approved such amendment or waiver (any such Lender referred to in clause (a), (b), (c), or (d) above being hereinafter referred to as an “Affected Lender”), the Borrower may, in addition to any other rights the Borrower may have hereunder or under applicable law, require, at its expense, any such Affected Lender to assign, at par, without recourse, all of its interest, rights, and obligations hereunder (including all of its Commitments and the Loans and other amounts at any time owing to it hereunder and the other Loan

-10-

Documents) to an Eligible Assignee specified by the Borrower, provided that (i) such assignment shall not conflict with or violate any law, rule or regulation or order of any court or other governmental authority, (ii) the Borrower shall have paid to the Affected Lender all monies (together with amounts due such Affected Lender under Section 2.2 hereof as if the Loans owing to it were prepaid rather than assigned) other than such principal owing to it hereunder, and (iii) the assignment is entered into in accordance with, and subject to the consents required by, Section 11.17 hereof (provided any assignment fees and reimbursable expenses due thereunder shall be paid by the Borrower).

SECTION 3. FEES, PAYMENTS, REDUCTIONS AND NOTATIONS.

          Section 3.1. Fees. The Borrower shall pay to the Administrative Agent, for itself and the benefit of the Lenders, the fees as set forth in that certain fee letter dated August 15, 2007, between the Borrower and the Administrative Agent.

          Section 3.2. Voluntary Prepayments. The Borrower shall have the privilege of prepaying without premium or penalty (except as set forth in Section 2.2 above) and in whole or in part (but, if in part, then: (i) in an amount not less than $1,000,000, 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 1.2 hereof remains outstanding) any Borrowing of Eurodollar Loans at any time upon three (3) Business Days prior notice by the Borrower to the Administrative Agent or, in the case of a Borrowing of Base Rate Loans, notice delivered by the Borrower to the Administrative 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, accrued interest thereon to the date fixed for prepayment plus any amounts due the Lenders under Section 2.2 hereof.

          Section 3.3. Mandatory Prepayments. (a) Asset Dispositions. (i) Subject to the terms of the Intercreditor Agreement, if the 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 Borrower, to the extent the aggregate amount of all such Net Cash Proceeds received by the Borrower 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 Borrower and the Restricted Subsidiaries as of such date, then (x) the Borrower shall promptly notify the Administrative Agent of such proposed Disposition or Event of Loss (including the amount of the estimated Net Cash Proceeds to be received by the Borrower or such Subsidiary in respect thereof) and (y) such Net Cash Proceeds shall be paid over to the Administrative Agent promptly upon receipt by the Borrower or such Restricted Subsidiary of the Net Cash Proceeds of such Disposition or Event of Loss for application as set forth herein. Subject to the terms of the Intercreditor Agreement, immediately upon receipt by the Borrower or such Restricted Subsidiary of such Net Cash Proceeds, the Administrative Agent shall apply such Net Cash Proceeds to the payment of all Obligations; 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 Borrower states in its notice of such event that the applicable Borrower or the applicable Subsidiary intends to reinvest, within 180 days of the

-11-

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 Administrative Agent shall deposit such Net Cash Proceeds in an account held by the Administrative Agent or one or more of its Affiliates 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 Administrative Agent shall return the amount of such Net Cash Proceeds to be reinvested to the Borrower. Subject to the terms of the Intercreditor Agreement, 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 Administrative Agent shall promptly apply such Net Cash Proceeds to the payment of all Obligations, until paid in full, and release the balance thereof to the Borrower.

          (b) Equity Issuances. If after the Closing Date the Borrower or any Subsidiary shall issue new equity securities (whether common preferred stock, or convertible debt permitted by Section 7.10(p) hereof or otherwise), other than equity securities issued in connection with the exercise of employee stock options and capital stock of the Borrower issued to the seller of an Acquired Business in connection with an Acquisition permitted hereby, the Borrower shall promptly notify the Administrative Agent of the estimated Net Cash Proceeds of such issuance to be received by or for the account of the Borrower or such Subsidiary in respect thereof. Promptly upon receipt by the Borrower or such Subsidiary of Net Cash Proceeds of such issuance, the Borrower shall prepay the Obligations in an aggregate amount equal to 100% of the amount of such Net Cash Proceeds. The amount of each such prepayment shall be applied to the outstanding Term Loans until paid in full. The Borrower acknowledges that its performance hereunder shall not limit the rights and remedies of the Lenders for any breach of Section 7.15 (Maintenance of Subsidiaries) or Section 8.1(j) (Change in Control) hereof or any other terms of the Loan Documents.

          (c) Debt Issuances. If after the Closing Date the Borrower or any Subsidiary shall issue any Indebtedness for Borrowed Money, other than Indebtedness for Borrowed Money permitted by 7.10 hereof (other than Indebtedness for Borrowed Money permitted by Section 7.10(p)), the Borrower shall promptly notify the Administrative Agent of the estimated Net Cash Proceeds of such issuance to be received by or for the account of the Borrower or such Subsidiary in respect thereof. Promptly upon receipt by the Borrower or such Subsidiary of Net Cash Proceeds of such issuance, the Borrower shall prepay the Obligations in an aggregate amount equal to 100% of the amount of such Net Cash Proceeds. The amount of each such prepayment shall be applied to the outstanding Term Loans until paid in full. The Borrower acknowledges that its performance hereunder shall not limit the rights and remedies of the Lenders for any breach of Section 7.10 hereof or any other terms of the Loan Documents.

          Section 3.4. Place and Application. All payments of principal, interest and fees shall be made to the Administrative Agent at its office at 111 West Monroe Street, Chicago, Illinois (or at such other place as the Administrative 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. Any payments received by the Administrative Agent after such time shall be

-12-

deemed received as of the opening of business on the next Business Day. All such payments shall be made in U.S. Dollars, in immediately available funds at the place of payment. 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 Administrative Agent to the Lenders in accordance with their Percentages on the date the Administrative Agent receives payment, or if the Administrative Agent receives payment later than 12:00 Noon Central Time, then no later than the next Business Day. Unless the Borrower otherwise requests, each prepayment shall be first applied to the Borrower’s Base Rate Loans and then to its Eurodollar Loans in the order in which their Interest Periods expire. Each partial prepayment pursuant to Section 3.2 or Section 3.3 shall be applied to the remaining amortization payments in the reverse order of maturity. Any prepayment of Eurodollar Loans shall be accompanied by any amount due the Lenders under Section 2.2 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, but subject to the Intercreditor Agreement, all payments and collections received in respect of the Obligations and all proceeds of the Collateral received, in each instance, by the Administrative Agent or any of the Lenders after the occurrence of an Event of Default shall be remitted to the Administrative Agent and distributed as follows:

          (a) first, to the payment of any outstanding costs and expenses incurred by the Administrative Agent in monitoring, verifying, protecting, preserving or enforcing the Liens on the Collateral or by the Administrative Agent in protecting, preserving or enforcing rights under the Loan Documents, and in any event all costs and expenses of a character which the Borrower has agreed to pay under Section 11.5 hereof (such funds to be retained by the Administrative Agent for its own account unless the Administrative 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 Administrative Agent);

          (b) second, to the payment of any outstanding interest or other fees or amounts due under the Term Notes and the other Loan Documents, in each case other than for principal, ratably as among the Administrative Agent and the Lenders in accord with the amount of such interest and other fees or amounts owing each;

          (c) third, to the payment of the principal of the Term Notes, and Hedging Liability, 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;

-13-

          (d) fourth, to the Administrative Agent and the Lenders ratably in accordance with the amounts of any other indebtedness, obligations or liabilities of the Borrower 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

        (e) fifth, to the Borrower or whoever else may be lawfully entitled thereto.

          Section 3.5. Notations and Requests. All Borrowings made against the Term Notes and the rates of interest applicable thereto, the maturity thereof, shall be recorded by the Lenders on their books or, at their option in any instance, endorsed on the reverse side of the Term Notes 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 Term Notes of the principal amount remaining unpaid thereon, the interest rates applicable thereto and the maturity thereof. Prior to any negotiation of any Term Note, the Lender holding such Term 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. Subject to the Intercreditor Agreement, the Obligations and Hedging Liability 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 Borrower and the 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 Borrower and the Guarantors and all proceeds of the foregoing; provided however that unless and until the Required Lenders otherwise elect (i) the Borrower and the Guarantors shall not be required to note the Administrative 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 Administrative 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 unpaid at the time of notification by a bonding company to the obligee of the bonding company’s rights under any agreement of indemnity with a Contractor; (d) 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 Foreign 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 Administrative Agent 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 Term Loan Agreement and the agreements providing such purchase money financing prohibit the creation of a further security interest therein. The Borrower agrees that it will, and will cause the Guarantors to, from time to time at the request of the Administrative 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 Administrative Agent or the Required Lenders may reasonably request in order to provide for or perfect such Liens on the Collateral. 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 shall be referred to herein as “Excess Stock Collateral”). In no event shall the Excess Stock Collateral secure the indebtedness, liabilities and obligations of the Borrower 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 of the Borrower shall be fully guaranteed by the Guarantors. Subject to 4.1, the Required Lenders may from time

-15-

to time require any Restricted Subsidiary which is a U.S. 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 Borrower shall within 30 days of request cause such Restricted Subsidiary to execute and deliver a Guarantee to the Administrative Agent together with such supporting resolutions, opinions and other showings as the Administrative Agent may reasonably require.

SECTION 5. REPRESENTATIONS AND WARRANTIES.

          The Borrower represents and warrants to the Administrative Agent and the Lenders as follows:

          Section 5.1. Organization and Qualification. The Borrower is duly organized, validly existing and in good standing as a corporation, under the laws of Delaware 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 Borrower 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 Borrower will notify the Administrative 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 Borrower or a Restricted Subsidiary are as of the date hereof owned, beneficially and of record, by the Borrower or such Restricted Subsidiary free and clear of all Liens not permitted hereby.

to grant to the Administrative 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 Administrative 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 Borrower and Guarantors and constitute valid and binding obligations of the Borrower 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 the Borrower or any 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 the Borrower or any Guarantor or any provision of the charter, articles of incorporation or organization or by-laws of the Borrower or any Guarantor or any covenant, indenture or agreement of the Borrower or the Guarantors or affecting any of their Properties, or result in the creation or imposition of any Lien on any Property of the Borrower or the Guarantors.

Neither the Borrower 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

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 the 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 the Borrower or any Guarantor to perform its obligations under, this Agreement or any other Loan Document or (b) have a Material Adverse Effect.

Section 7.13. Capital and Certain other Restricted Expenditures. The Borrower will not, nor will it permit any Restricted Subsidiary to, make, or (without duplication) become obligated to make, any Capital Expenditure (other than Capital Expenditures which constitute Permitted Acquisitions and investments permitted by Section 7.12(j), (n) or (o) hereof) or apply for a letter of credit (whether hereunder or otherwise) supporting an obligation of any Strategic Venture described in Section 7.12(o) or guarantee any Indebtedness for Borrowed Money of any such Strategic Venture, if after giving effect thereto the aggregate amount expended (other than in the form of capital stock of the Borrower) for such purposes during the twelve-month period ending on the date of the expenditure in question when taken together with the face amount of such letters of credit issued during such period and such indebtedness so guaranteed incurred during such period, would exceed the sum of (i) 2.00% of the arithmetic average of the unrealized revenue from contracts in progress of the Borrower and its Restricted Subsidiaries (computed in accord with the past practice of the Borrower) as of the last day of each of the four calendar quarters most recently completed prior to the computation in question, (ii) the net cash proceeds received by the Borrower and the Restricted Subsidiaries during the same period from sales of assets (including stock of Restricted Subsidiaries permitted by Sections 7.14 and/or 7.15 hereof but excluding sales of inventory in the ordinary course of business) and (iii) the maximum amount of dividends which the Borrower could pay under Section 7.16 as of the date of the expenditure or application in question.
Section 7.14. Mergers, Consolidations and Sales.

-35-

recourse) any of its notes or accounts receivable (other than sales of accounts receivable by the Borrower and its Restricted Subsidiaries to any Restricted Subsidiary, sale and leaseback transactions between the Borrower 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 Borrower 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 Borrower 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 Borrower and sales by Restricted Subsidiaries of all or substantially all of their assets to the Borrower, (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 Administrative 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 Borrower, necessary for the operation of the business of the Borrower 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 Administrative 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 Borrower 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 Borrower and the Restricted Subsidiaries as of such date. The Administrative 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 Borrower 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 Borrower 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 Borrower 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 Borrower has determined that the continued ownership of the Restricted Subsidiary (or the

-36-

minority interest therein to be disposed of) in question is no longer appropriate in light of the then needs and strategic objectives of the Borrower 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 Borrower or any other Restricted Subsidiary is paid in full, and all guarantees or other support undertakings provided by the Borrower 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 Administrative 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 Borrower 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 Borrower 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 Borrower 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) $125,000,000 plus (but not minus in the case of a deficit) 50% of Net Income for the period (taken as a single accounting period) from July 1, 2007 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 Borrower 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 Borrower shall, and shall cause each of the Restricted Subsidiaries to, promptly notify the Administrative 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 the Borrower or any member of its 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

-37-

occurrence of any other event with respect to any Plan which would result in the incurrence by the Borrower or any of its Restricted Subsidiaries of any material liability, fine or penalty, or any material increase in the contingent liability of the Borrower or any of its 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 Borrower 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 Borrower and the Restricted Subsidiaries taken as a whole.

          Section 7.19. Burdensome Contracts With Affiliates. The Borrower 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 Borrower) on terms and conditions which are less favorable to the Borrower 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 Borrower 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 Borrower 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 Administrative 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 Borrower 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 Borrower and the Restricted Subsidiaries would be changed in any material respect from the general nature of the business engaged in by the Borrower and the Restricted Subsidiaries on the date of this Agreement, it being understood that this Section does not prohibit the FR Acquisition.

          Section 7.23. Use of Proceeds. The Borrower shall use the proceeds of the Term Loan hereunder to pay a portion of the consideration for the FR Acquisition and to pay the reasonable costs and expenses incident thereto, it being understood that if the FR Acquisition closes prior the Closing Date, the Borrower shall use the proceeds of the Term Loan to repay advances under

-38-

the Revolving Credit Agreement and/or advances from the Borrower’s cash-on-hand, in each case to be used to pay a portion of the purchase price of the FR Acquisition.

The Lenders acknowledge and agree that the Administrative Agent is not a trustee or other fiduciary for them. The Administrative Agent may resign at any time by sending twenty (20) days prior written notice to the Borrower and the Lenders and may be removed by the Required Lenders upon twenty (20) days prior written notice to the Borrower and the Lenders. In the event of any such resignation or removal, the Required Lenders may appoint a new agent, with the consent of the Borrower (which consent shall not be required if any Default or Event of Default has occurred and is continuing and which consent, if required,

-54-

shall not be unreasonably withheld), which shall succeed to all the rights, powers and duties of the Administrative Agent hereunder and under the other Loan Documents. Any resigning or removed Administrative Agent shall be entitled to the benefit of all the protective provisions hereof with respect to its acts as an agent or issuer hereunder, but no successor Administrative Agent shall in any event be liable or responsible for any actions of its predecessor. If the Administrative Agent resigns or is removed and no successor is appointed, the rights and obligations of such Administrative Agent shall be automatically assumed by the Required Lenders and (i) the Borrower and Guarantors shall be directed to make all payments due each Lender hereunder directly to such Lender and (ii) the Administrative Agent’s rights in the Collateral Documents shall be assigned without representation, recourse or warranty to the Lenders as their interests may appear.

          Section 10.2. Rights as a Lender. The Administrative Agent has and reserves 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 it were not the Administrative Agent and the terms “Lender” or “Lenders” as used herein and in all of such documents shall, unless the context otherwise expressly indicates, include the Administrative Agent in its individual capacity 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 Administrative Agent makes 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 Term Notes or any of the other Obligations or of any of the other Loan Documents or of the Liens provided for thereby or of any other documents called for hereby or thereby or of the Collateral. The Administrative Agent need not verify the worth or existence of the Collateral. Neither the Administrative Agent nor any director, officer, employee, agent or representative thereof (including any security trustee therefor) shall in any 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 Administrative Agent 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 it to be authorized to act on behalf of the Borrower), unless it has actual knowledge of the untruthfulness of same. The Administrative Agent may execute any of its 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 Administrative Agent 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 Administrative Agent shall be entitled to assume that no Default or Event of Default exists unless notified to the contrary by a Lender. The Administrative Agent shall in all events be fully protected in acting or failing to act in accord with the instructions of the Required Lenders.

-55-

Upon the occurrence of an Event of Default hereunder, the Administrative 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 Administrative Agent shall take or refrain from taking such actions as it deems appropriate and in the best interest of all Lenders. The Administrative 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 Administrative Agent by reason of taking or continuing to take any such action. The Administrative Agent may treat the owner of any Term Note as the holder thereof until written notice of transfer shall have been filed with the Administrative Agent signed by such owner in form satisfactory to the Administrative Agent. Each Lender acknowledges that it has independently and without reliance on the Administrative Agent 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 Borrower. It shall be the responsibility of each Lender to keep itself informed as to the creditworthiness of the Borrower and the Guarantors and the Administrative Agent shall have no liability to any Lender with respect thereto.

          Section 10.4. Costs and Expenses. Each Lender agrees to reimburse the Administrative Agent for all costs and expenses suffered or incurred by them or any security trustee in performing their duties hereunder and under the other Loan Documents, or in the exercise of any right or power imposed or conferred upon them hereby or thereby, to the extent that they are not promptly reimbursed for same by the Borrower or out of the Collateral, all such costs and expenses to be borne by the Lenders ratably in accordance with the amounts of their respective Commitments.

          Section 10.5. Indemnity. The Lenders shall ratably indemnify and hold the Administrative Agent and its directors, officers, employees, agents, representatives or attorneys-in-fact (including as such any security trustee 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 Borrower 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. [Intentionally Omitted]

          Section 10.7. Conflict. In the event of a conflict between the provisions of this Section 10 and the provisions of any Collateral Document regarding the rights, duties and obligations of the Administrative Agent, the provisions of this Section 10 shall govern.

          Section 10.8. Hedging Liability. By virtue of a Lender’s execution of this Agreement or an assignment agreement pursuant to Section 11.17 hereof, as the case may be, any Affiliate of such Lender with whom the Borrower or any Subsidiary has entered into an agreement creating

-56-

Hedging Liability shall be deemed a Lender party hereto for purposes of any reference in a Loan Document to the parties for whom the Administrative Agent is acting, it being understood and agreed that the rights and benefits of such Affiliate under the Loan Documents consist 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 3.4 hereof. In connection with any such distribution of payments and collections, the Administrative Agent shall be entitled to assume no amounts are due to any Lender or its Affiliate with respect to Hedging Liability unless such Lender has notified the Administrative Agent in writing of the amount of any such liability owed to it or its Affiliate prior to such distribution.

          Section 10.9. Designation of Additional Administrative Agents. The Administrative Agent shall have the continuing right, with the consent of the Borrower (such consent not to be unreasonably withheld or delayed) for purposes hereof, at any time and from time to time to designate one or more of the Lenders (and/or its or their Affiliates) as “syndication agents,” “documentation agents,” “arrangers,” or other designations for purposes hereto, but such designation shall have no substantive effect, and such Lenders and their Affiliates shall have no additional powers, duties or responsibilities as a result thereof.

          Section 10.10. Authorization to Release or Subordinate or Limit Liens. The Administrative Agent is hereby irrevocably authorized by each of the Lenders to (a) release any Lien covering any Collateral that is sold, transferred, or otherwise disposed of in accordance with the terms and conditions of this Agreement and the relevant Collateral Documents (including a sale, transfer, or disposition permitted by the terms of Section 7.14 hereof or which has otherwise been consented to in accordance with Section 11.4 hereof), (b) release or subordinate any Lien on Collateral consisting of goods financed with purchase money indebtedness or under a Capital Lease to the extent such purchase money indebtedness or Capitalized Lease Obligation, and the Lien securing the same, are permitted by Sections 7.10(h) and 7.11(e) hereof, and (c) reduce or limit the amount of the indebtedness secured by any particular item of Collateral to an amount not less than the estimated value thereof to the extent necessary to reduce mortgage registry, filing and similar tax.

          Section 10.11. Authorization to Enter into, and Enforcement of, the Collateral Documents. Each of the Administrative Agent and the Collateral Agent is hereby irrevocably authorized by each of the Lenders to execute and deliver the Collateral Documents (including the Intercreditor Agreement) on behalf of each of the Lenders and their Affiliates and to take such action and exercise such powers under the Collateral Documents as the Administrative Agent or Collateral Agent, as applicable, considers appropriate, provided neither the Administrative Agent nor the Collateral Agent shall amend the Collateral Documents unless such amendment is agreed to in writing by the Required Lenders. Each Lender acknowledges and agrees that it will be bound by the terms and conditions of the Collateral Documents upon the execution and delivery thereof by the Administrative Agent and/or Collateral Agent, as applicable. Except as otherwise specifically provided for herein, no Lender (or its Affiliates) other than the Collateral Agent shall have the right to institute any suit, action or proceeding in equity or at law for the foreclosure or other realization upon any Collateral or for the execution of any trust or power in respect of the Collateral or for the appointment of a receiver or for the enforcement of any other remedy under the Collateral Documents; it being understood and intended that no one or more of the Lenders

-57-

(or their Affiliates) shall have any right in any manner whatsoever to affect, disturb or prejudice the Lien of the Collateral Agent (or any security trustee therefor) under the Collateral Documents by its or their action or to enforce any right thereunder, and that all proceedings at law or in equity shall be instituted, had, and maintained by the Collateral Agent (or its security trustee) in the manner provided for in the relevant Collateral Documents for the benefit of the Lenders and their Affiliates.

SECTION 11. MISCELLANEOUS.

          Section 11.1. Withholding Taxes. (a) Payments Free of Withholding. Except as otherwise required by law and subject to Section 11.1(b) hereof, each payment by the 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 the Borrower or such Guarantor is domiciled, any jurisdiction from which the 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 Administrative Agent free and clear of such taxes (including such taxes on such additional amount) is equal to the amount which that Lender or the Administrative Agent (as the case may be) would have received had such withholding not been made. If the Administrative 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 Borrower shall reimburse the Administrative Agent or that Lender for that payment on demand in the currency in which such payment was made. If the Borrower 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 Administrative Agent on whose account such withholding was made (with a copy to the Administrative Agent if not the recipient of the original) on or before the thirtieth day after payment. If any Lender or the Administrative 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 Borrower or any Guarantor and evidenced by such a tax receipt, such Lender or Administrative 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 Borrower or such Guarantor as applicable, such amount as such Lender or Administrative Agent reasonably determines is attributable to such deduction or withholding and which will leave such Lender or Administrative Agent (after such payment) in no better or worse position than it would have been in if the Borrower 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 Administrative Agent to arrange its tax affairs in whatever manner it thinks fit nor oblige any Lender or the Administrative Agent to disclose any information relating to its tax affairs or any computations in connection with such taxes.

-58-

          (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 Borrower and the Administrative 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 Term Loans) or Form W8-ECI (relating to all amounts to be received by such Lender, including fees, pursuant to the Loan Documents and the Term Loans) of the United States Internal Revenue Service. Thereafter and from time to time, each Lender shall submit to the Borrower and the Administrative 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 Borrower in a written notice, directly or through the Administrative 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 Term 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 Borrower or Administrative 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 Borrower and the Administrative 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 Borrower 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 Term 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.

-59-

          Section 11.3. No Waiver, Cumulative Remedies. No delay or failure on the part of the Administrative Agent or any Lender or on the part of the Administrative Agent 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 Administrative Agent, the Lenders and 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 Borrower, (b) the Required Lenders, and (c) if the rights or duties of the Administrative Agent are affected thereby, the Administrative Agent; 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 fee payable hereunder without the consent of the Lender to which such payment is owing or which has committed to make such Loan (or participate therein) hereunder; and

          (ii) no amendment or waiver pursuant to this Section 11.4 shall, unless signed by each Lender, extend the Maturity Date, change the definition of 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 Borrower agrees to pay on demand all reasonable costs and expenses of the Administrative 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 Administrative 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 Term Notes and the other Obligations, and all reasonable costs and expenses (including reasonable attorneys’ fees) incurred by the Administrative Agent, 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 Administrative Agent believes such supplements to be appropriate or desirable. The Borrower agrees to indemnify and save the Lenders, the Administrative Agent and any security trustee for the Administrative Agent or the Lenders harmless from any and all liabilities, losses, costs and expenses incurred by the Lenders or the Administrative Agent in connection with any action, suit or proceeding brought against the Administrative Agent, any security trustee or any Lender by

-60-

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 Administrative 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 Borrower agrees that it 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.

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.

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 Borrower shall not be responsible for the costs incurred by any Lender in connection with such participations.

          Section 11.17. Assignments. (a) Any Lender may at any time assign to one or more Eligible Assignees all or a portion of such Lender’s rights and obligations under this Agreement (including all or a portion of its Commitment and the Loans at the time owing to it); provided that any such assignment shall be subject to the following conditions:

          (i) Minimum Amounts. (A) In the case of an assignment of the entire remaining amount of the assigning Lender’s Commitment and the Loans at the time owing to it or in the case of an assignment to a Lender, an Affiliate of a Lender or an Approved Fund, no minimum amount need be assigned; and (B) in any case not described in subsection (a)(i)(A) of this Section, the aggregate amount of the Commitment or, if the applicable Commitment is not then in effect, the principal outstanding balance of the Loans of the assigning Lender subject to each such assignment (determined as of the date the Assignment and Acceptance with respect to such assignment is delivered to the Administrative Agent or, if “Effective Date” is specified in the

-62-

Assignment and Acceptance, as of the Effective Date) shall not be less than $1,000,000, unless each of the Administrative Agent and, so long as no Event of Default has occurred and is continuing, the Borrower otherwise consents (each such consent not to be unreasonably withheld or delayed);

          (ii) Proportionate Amounts. Each partial assignment shall be made as an assignment of a proportionate part of all the assigning Lender’s rights and obligations under this Agreement with respect to the Loan or the Commitment assigned, except that this clause (ii) shall not prohibit any Lender from assigning all or a portion of its rights and obligations among separate Credits on a non-pro rata basis.

          (iii) Required Consents. No consent shall be required for any assignment except to the extent required by Section 11.17(a)(i)(B) and, in addition:

          (a) the consent of the Borrower (such consent not to be unreasonably withheld or delayed) shall be required unless (x) an Event of Default has occurred and is continuing at the time of such assignment or (y) such assignment is to a Lender, an Affiliate of a Lender or an Approved Fund; and

          (b) the consent of the Administrative Agent (such consent not to be unreasonably withheld or delayed) shall be required for assignments to a Person who is not a Lender, an Affiliate of a Lender or an Approved Fund.

          (iv) Assignment and Acceptance. The parties to each assignment shall execute and deliver to the Administrative Agent an Assignment and Acceptance, together with a processing and recordation fee of $3,500 (provided such fee shall not be required for assignments to an Affiliate of a Lender), and the assignee, if it is not a Lender, shall deliver to the Administrative Agent an Administrative Questionnaire.

          (v) No Assignment to Borrower or Parent. No such assignment shall be made to the Borrower or any of its Affiliates or Subsidiaries.

          (vi) No Assignment to Natural Persons. No such assignment shall be made to a natural person.

Subject to acceptance and recording thereof by the Administrative Agent pursuant to Section 11.17(b) hereof, from and after the effective date specified in each Assignment and Acceptance, the assignee thereunder shall be a party to this Agreement and, to the extent of the interest assigned by such Assignment and Acceptance, have the rights and obligations of a Lender under this Agreement, and the assigning Lender thereunder shall, to the extent of the interest assigned by such Assignment and Acceptance, be released from its obligations under this Agreement (and, in the case of an Assignment and Acceptance covering all of the assigning Lender’s rights and obligations under this Agreement, such Lender shall cease to be a party hereto) but shall continue to be entitled to the benefits of Sections 11.5 and 11.7 with respect to facts and circumstances occurring prior to the effective date of such assignment. Any assignment or transfer by a Lender of rights or obligations under this Agreement that does not

-63-

comply with this Section shall be treated for purposes of this Agreement as a sale by such Lender of a participation in such rights and obligations in accordance with Section 11.16 hereof.

          (b) Register. The Administrative Agent, acting solely for this purpose as an agent of the Borrower, shall maintain at one of its offices in Chicago, Illinois, a copy of each Assignment and Acceptance delivered to it and a register for the recordation of the names and addresses of the Lenders, and the Commitments of, and principal amounts of the Loans owing to, each Lender pursuant to the terms hereof from time to time (the “Register”). The entries in the Register shall be conclusive, and the Borrower, the Administrative Agent, and the Lenders may treat each Person whose name is recorded in the Register pursuant to the terms hereof as a Lender hereunder for all purposes of this Agreement, notwithstanding notice to the contrary. The Register shall be available for inspection by the Borrower and any Lender, at any reasonable time and from time to time upon reasonable prior notice.

          (c) Any Lender may at any time pledge or grant a security interest in all or any portion of its rights under this Agreement to secure obligations of such Lender, including any such pledge or grant to a Federal Reserve Bank, and this Section shall not apply to any such pledge or grant of a security interest; provided that no such pledge or grant of a security interest shall release a Lender from any of its obligations hereunder or substitute any such pledgee or secured party for such Lender as a party hereto; provided further, however, the right of any such pledgee or grantee (other than any Federal Reserve Bank) to further transfer all or any portion of the rights pledged or granted to it, whether by means of foreclosure or otherwise, shall be at all times subject to the terms of this Agreement.

          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 ADMINISTRATIVE AGENT, THE LENDERS AND THE BORROWER 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 ADMINISTRATIVE AGENT, THE LENDERS AND THE BORROWER ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF COOK COUNTY, ILLINOIS. THE BORROWER WAIVES IN ALL DISPUTES ANY OBJECTION THAT THEY MAY HAVE TO THE LOCATION OF THE COURT CONSIDERING THE DISPUTE.

          (b) OTHER JURISDICTIONS. THE BORROWER AGREES THAT THE ADMINISTRATIVE AGENT, AND EACH OF THE LENDERS SHALL HAVE THE RIGHT TO PROCEED AGAINST THE BORROWER OR ITS PROPERTY (“PROPERTY”) IN A COURT IN ANY LOCATION OR JURISDICTION TO

-64-

ENABLE THE ADMINISTRATIVE AGENT OR ANY LENDER TO REALIZE ON PROPERTY, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER ENTERED IN FAVOR OF THE ADMINISTRATIVE AGENT OR ANY LENDER AND, WITHOUT PREJUDICE TO THE GENERALITY OF THE FOREGOING, THE BORROWER AGREES THAT THE ADMINISTRATIVE 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 THE BORROWER OR ANY OF ITS PROPERTY IS LOCATED.

          (c) Jury Trial Waiver. The Borrower, the Administrative 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. Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any Loan to the 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 11.21 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.

          Section 11.21. USA Patriot Act. Each Lender that is subject to the requirements of the USA Patriot Act (Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”) hereby notifies the Borrower that pursuant to the requirements of the Act, it is required to obtain, verify, and record information that identifies the Borrower, which information includes the name and address of the Borrower and other information that will allow such Lender to identify the Borrower in accordance with the Act.

          Section 11.22. Confidentiality. Each of the Administrative Agent and the Lenders severally agrees to maintain the confidentiality of the Information (as defined below), except that Information may be disclosed (a) to its and its Affiliates’ directors, officers, employees and agents, including accountants, legal counsel and other advisors to the extent any such Person has a need to know such Information (it being understood that the Persons to whom such disclosure is made will first be informed of the confidential nature of such Information and instructed to keep such Information confidential), (b) to the extent requested by any regulatory authority (including any self-regulatory authority, such as the National Association of Insurance Commissioners), (c) to the extent required by applicable laws or regulations or by any subpoena or similar legal process, (d) to any other party hereto, (e) in connection with the exercise of any remedies hereunder or under any other Loan Document or any suit, action or proceeding relating to this Agreement or any other Loan Document or the enforcement of rights hereunder or thereunder, (f) subject to an agreement containing provisions substantially the same as those of

-65-

this Section, to (A) any assignee of or participant in, or any prospective assignee of or participant in, any of its rights or obligations under this Agreement or (B) any actual or prospective counterparty (or its advisors) to any swap or derivative transaction relating to the Borrower or any Subsidiary and its obligations, (g) with the prior written consent of the Borrower, (h) to the extent such Information (A) becomes publicly available other than as a result of a breach of this Section or (B) becomes available to the Administrative Agent or any Lender on a non-confidential basis from a source other than the Borrower or any Subsidiary or any of their directors, officers, employees or agents, including accountants, legal counsel and other advisors, (i) to rating agencies if requested or required by such agencies in connection with a rating relating to the Loans or Commitments hereunder, or (j) to entities which compile and publish information about the syndicated loan market, provided that only basic information about the pricing and structure of the transaction evidenced hereby may be disclosed pursuant to this subsection (j). For purposes of this Section, “Information” means all information received from the Borrower or any of the Subsidiaries or from any other Person on behalf of the Borrower or any Subsidiary relating to the Borrower or any Subsidiary or any of their respective businesses, other than any such information that is available to the Administrative Agent or any Lender on a non-confidential basis prior to disclosure by the Borrower or any of its Subsidiaries or from any other Person on behalf of the Borrower or any of the Subsidiaries.

          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 this Term Loan Agreement, the Term 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 Administrative Agent and been distributed among the Lenders as contemplated by Section 3.4 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 3.4 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.

September 19, 2007

          For value received, the undersigned, EMCOR GROUP, INC., a Delaware corporation (“Borrower”), hereby promises to pay to the order of ________________________ ______________________ (the “Lender”), at the principal office of Bank of Montreal, Chicago Branch, in Chicago, Illinois, the aggregate unpaid principal amount of each Term Loan made by the Lender to the Borrower pursuant to the Term Loan Agreement on the due date therefore as specified in the Term Loan Agreement, together with interest on the principal amount of each Term Loan from time to time outstanding hereunder at the rates, and payable in the manner and on the dates specified in the Term Loan Agreement.

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

          This Note is one of the Term Notes referred to in the Term Loan Agreement dated as of September 19, 2007, among the Borrower, Bank of Montreal, as Administrative Agent, and the Lenders from time to time party thereto (the “Term Loan Agreement”), and this Note and the holder hereof are entitled to all the benefits provided for thereby or referred to therein, to which Term Loan Agreement reference is hereby made for a statement thereof. All defined terms used in this Note, except terms otherwise defined herein, shall have the same meaning as in the Term Loan Agreement.

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

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

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

FORM OF OPINION OF COUNSEL

EXHIBIT B

September    , 2007

Bank of Montreal, as Administrative Agent
111 West Monroe Street
Chicago, IL 60690
Harris, N.A., as Collateral Agent, and
Lenders from time to time party to
the Term Loan 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 “Guarantors”, and collectively with the Company, the “Organizations”) in connection with the Term Loan Agreement dated as of September , 2007 (the “Term Loan Agreement”) by and among the Company and Bank of Montreal, individually and as Administrative Agent, and the Lenders which are or become parties thereto, in connection with which a term loan is being made available by you to the Company.

          This opinion is being delivered pursuant to Section 6(m) of the Term Loan Agreement. Capitalized terms used and not defined herein shall have the respective meanings assigned to such terms in the Term Loan Agreement.

          In connection with this opinion, I have reviewed the Term Loan Agreement; the form of Term Note; the form of Guaranty Agreement dated as of September , 2007 made by the Guarantors (as such term is defined in such Guaranty Agreement) in favor of the Guaranteed Creditors (as such term is defined in such Guaranty Agreement), the form of Assumption and Supplemental Guaranty Agreement dated as of September , 2007 made by certain Guarantors (as such term is defined in the Amended and Restated Credit Agreement dated as of October 14, 2005 by and among the Company and Certain of Its Subsidiaries and Harris N.A. and the Lenders which are or became parties thereto (the “Revolving Credit Agreement”)) in favor of the Guaranteed Creditors (as that term is defined in the Amended and Restated Guaranty Agreement dated as of October 14, 2005, which the Supplemental Guaranty Agreement supplements); the form of Second Amended and Restated Pledge Agreement dated as of September , 2007 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 N.A., as Agent (the “Agent”); the form of Second Amended and Restated Security Agreement dated as of September , 2007 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 N.A. (as such term is defined in such Security Agreement), as Agent (the “Agent”), and the Intercreditor and Collateral Agency Agreement dated as of September   ,

C-2

2007 by and among Harris N.A., as Collateral Agent and Revolver Agent, and Bank of Montreal, as Term Loan Agent (as such terms are defined therein), which the Company and the Guarantors have acknowledged and consented to (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 organization document) of each Guarantor which is a limited liability company, certified by Members, a Manager or an officer of each such Guarantor;

          (iii) a copy of the certificate of limited partnership of each Guarantor which is a limited partnership, certified by a general partner or officer of each such Guarantor;

          (iv) a certificate (or the equivalent thereof), dated as of a date no earlier than 30 days prior to the date hereof, as to the good standing and/or legal existence of each Organization issued by the Secretary of State of the state of such Organization’s organization provided such state issues such certificate or equivalent;

          (v) a copy of the by-laws of each Organization which is a corporation, certified by the Secretary or the Assistant Secretary or Clerk or Assistant Clerk of such Organization as being the by-laws of such Organization as in effect on the date hereof;

          (vi) a copy of the limited liability company agreement or operating agreement of each Guarantor which is a limited liability company, certified by Members, a Manager or an officer of each such Guarantor as being the limited liability company agreement or operating agreement of such Guarantor as in effect on the date hereof;

          (vii) a copy of the limited partnership agreement of each Guarantor which is a limited partnership, certified by an officer of the general partner of each such Guarantor or the officer of each such Guarantor as being the limited partnership agreement of such Guarantor as in effect on the date hereof;

          (viii) copies of certain resolutions adopted by the board of directors of each Organization which is a corporation, authorizing the execution, delivery and performance of the terms and provisions of the Loan Documents to which such Organization is party, each certified by the Secretary or Assistant Secretary or the Clerk or Assistant Clerk of such Organization;

          (ix) copies of certain resolutions adopted by the members, Board of Managers or Managers of each Guarantor which is a limited liability company, authorizing the

C-3

execution, delivery and performance of the terms and provisions of the Loan Documents to which such Guarantor is party, each certified by Members, a Manager, or an officer of such Guarantor; and

          (x) copies of certain resolutions adopted by the general partner of each Guarantor which is a limited partnership, authorizing the execution, delivery, and performance of the terms and provisions of the Loan Documents to which such Guarantor is a party, each certified by the Secretary of the general partner of such 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 Manager of the Organizations or of officers of the general partners of Organizations that are limited partnerships or of officers 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

C-4

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. § 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.

C-5

          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. Except as set forth in the Side Letter referred to in the Credit Agreement, 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 which is a corporation or a limited liability company 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 from you. Each Guarantor has the corporate, limited liability company, limited partnership, or other power to guarantee all of the indebtedness, obligations and liabilities of the Company to you pursuant to the Term Loan 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, obligations 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.

C-6

          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, 2006 or in the Company’s Form 10-Q for the fiscal quarter ended June 30, 2007, 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
Executive Vice President
and General Counsel

          (q) all Accessions and additions to, and substitutions and replacements of, any and all of the foregoing; and

          (r) all Proceeds and products of the foregoing, and all insurance of the foregoing and proceeds thereof;

(all of the foregoing being herein referred to as the “Collateral”); provided, however, that: (i) no lien is granted on any asset subject to a lien permitted by clause (e), (i), (j), (k) or (l) (as to liens on fixed assets only) or (m) or (n) (insofar as (n) relates to the extension, renewal or replacement of a lien permitted by subsections of Section 7.11 of the Credit Agreement identified in this clause) or (o) of the Credit Agreement, (ii) no lien is granted on the capital stock of any Unrestricted Subsidiary or on the capital stock or assets of any Designated Foreign Restricted Subsidiary; (iii) no lien is granted on real property unless and until the Required Lenders so require; (iv) no lien is 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 in such contract, license, permit or franchise (or in any rights or property obtained by such Debtor under such contract, license, permit or franchise); (v) no lien is 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; (vi) no lien is granted on any rights or property to the extent that such rights or property secure purchase money financing therefor permitted by the Credit Agreement, Term Loan Agreement, and the agreements providing such purchase money financing prohibit the creation of a further security interest therein; (vii) liens granted may be subject and subordinate to liens permitted by clauses (a), (b), (c), (e), (f), (g), (h), (j), (k), (n), (o), (p) and (q) of Sections 7.11 of the Credit Agreement and Term Loan Agreement; (viii) liens need not be perfected 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 of the City of New York pledged to the City of New York in lieu of retainage; and (ix) 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 required to be pledged by the other provisions of the Credit Agreement and Term Loan Agreement) having a fair value of less than $1,000,000 in any instance and $5,000,000 in the aggregate; but, provided further, that (A) notwithstanding anything set forth above to the contrary, to the extent not prohibited by law,

- 4 -

the Agent has and shall at all times have a security interest in all rights to payments of money due or to become due under any such contract, contract right, or similar general intangible and all other proceeds thereof and (B) if and when the prohibition which prevents the granting of a security interest in any such Property is removed, terminated or otherwise becomes unenforceable as a matter of law, the Agent will be deemed to have, and at all times to have had, a security interest in such Property and the Collateral will be deemed to include, and at all times to have included, such Property. All terms which are used herein which are defined in the Uniform Commercial Code of the State of Illinois as in effect from time to time (“UCC”) shall have the same meanings herein as such terms are defined in the UCC, unless this Agreement shall otherwise specifically provide. For purposes of this Agreement, the term “Receivables” means all rights to the payment of a monetary obligation, whether or not earned by performance, and whether evidenced by an Account, Chattel Paper, Instrument, General Intangible or otherwise.

          (b) This Agreement is made and given to secure, and shall secure, the payment and performance of: (i) each of (A) any and all indebtedness, obligations and liabilities of the Borrowers to the Secured Creditors, or any of them individually, evidenced by or otherwise arising out of or relating to the Credit Agreement, the Term Loan Agreement or any promissory note of any Borrower heretofore or hereafter issued under the Credit Agreement or the Term Loan Agreement; (B) any and all obligations of the Revolver Borrowers, or any of them individually, to reimburse the Revolver Agent or any Revolver Lender with respect to any letter of credit or banker’s acceptance issued to or for the account of the Revolver Borrowers, or any of them individually, under the Credit Agreement; (C) any and all obligations of the Borrowers, or any of them individually, to the Secured Creditors, or any of them individually, with respect to Hedging Liability; and (D) any and all liabilities of the Borrowers or the Debtors, or any of them individually, arising out of any guaranty issued by the Borrowers or the Debtors, or any of them individually, relating to the foregoing or any part thereof, as well as for any and all other indebtedness, obligations and liabilities of the Borrowers and the Debtors, or any of them individually, to the Agent or the Secured Creditors, or any of them individually, evidenced by or otherwise arising out of or relating to this Agreement, the Guaranties or any other Loan Document; in each case, whether now existing or hereafter arising (and whether arising before or after the filing of a petition in bankruptcy), due or to become due, direct or indirect, absolute or contingent, and howsoever evidenced, held or acquired, and owing in any currency; and (ii) any and all expenses and charges, legal or otherwise, suffered or incurred by the Agent or the Secured Creditors, or any of them individually, in collecting or enforcing any of such indebtedness, obligations or liabilities or in realizing on or protecting or preserving any security therefor, including, without limitation, the lien and security interest granted to the Agent in the Collateral hereby (all of the foregoing being hereinafter referred to as the “Obligations”). Notwithstanding anything in this Agreement to the contrary, the right of recovery against any Debtor under this Agreement shall not exceed $1 less than the lowest amount which would render such Debtor’s obligations under this Agreement void or voidable under applicable law, including fraudulent conveyance law.

          Section 3. Covenants, Agreements, Representations and Warranties. Each Debtor hereby covenants and agrees with, and represents and warrants to, the Agent and each Secured Creditor that:

- 5 -

          (a) Each Debtor is a duly organized and validly existing in good standing under the laws of the state of its organization. No Debtor shall change its state of organization without the Agent’s prior written consent (which consent shall not be unreasonably withheld or delayed). Each Debtor’s chief executive office and principal place of business is at the location listed opposite such Debtor’s name under column 2 on Schedule A attached hereto; and such Debtor has no other executive offices or places of business (other than operating job sites in the ordinary course of such Debtor’s business) other than those listed opposite such Debtor’s name under column 3 on Schedule A attached hereto. Each Debtor’s organizational identification number is set forth under its name in column 1 on Schedule A attached hereto. The Collateral owned or leased by each Debtor is and shall remain in such Debtor’s possession or control at the locations listed opposite such Debtor’s name under column 4 on Schedule A attached hereto opposite such Debtors’s name or is or shall be located at such Debtor’s then operating job sites in the ordinary course of its business or is or shall be in transit to or between any of the foregoing locations (collectively, the “Permitted Collateral Locations”) other than temporarily in the ordinary course of business. If for any reason any Collateral is at any time kept or located at a location other than a Permitted Collateral Location, the Agent shall nevertheless have and retain a lien on and security interest in such Collateral. No Debtor shall move its chief executive office or maintain a place of business at a location other than those specified under columns 2 and/or 3 on Schedule A attached hereto other than temporarily in the ordinary course of business or permit any Collateral in excess of $1,000,000 to be located at a location other than a Permitted Collateral Location other than temporarily in the ordinary course of business or a job site, in each case without first providing the Agent 30 days prior written notice of such Debtor’s intent to do so; provided, however, that each Debtor shall at all times maintain its chief executive office and places of business in the United States of America and, with respect to any new chief executive office or place of business or location of Collateral, such Debtor shall have taken all action reasonably requested by the Agent or any Secured Creditor to maintain the lien and security interest of the Agent in the Collateral at all times fully perfected and in full force and effect. The execution and delivery of this Agreement, and the observance and performance of each of the matters and things herein set forth, will not (i) contravene or constitute a default under any provision of law or any judgment, injunction, order or decree binding upon any Debtor or any provision of any Debtor’s organizational documents (e.g.certificate of incorporation, articles of incorporation, by-laws, certificate of formation, limited liability company operating agreement or partnership agreement, as applicable) or any covenant, indenture or agreement of or affecting any Debtor or any of its property or (ii) result in the creation or imposition of any lien or encumbrance on any property of any Debtor except for the lien and security interest granted to the Agent in the Collateral hereunder. Each Debtor’s organizational registration number (if any) is set forth on Schedule A attached hereto.

          (b) The Collateral and every part thereof is and shall be free and clear of all security interests, liens (including, without limitation, mechanics’, laborers’ and statutory liens), attachments, levies and encumbrances of every kind, nature and description and whether voluntary or involuntary, except for the lien and security interest of the Agent therein and other liens permitted by the Credit Agreement or the Term Loan Agreement (herein, the “Permitted Encumbrances”).

- 6 -

          (c) Subject to Sections 4(a), 6(c) and 7(a) hereof, no Debtor shall without the Agent’s prior written consent, sell, assign, mortgage, lease or otherwise dispose of the Collateral or any interest therein, except that (i) until an Event of Default has occurred and is continuing and thereafter until notified by the Agent that it intends to foreclose or otherwise realize upon such Collateral, each Debtor may use and lease its Collateral to the extent not prohibited by the terms of the Credit Agreement or the Term Loan Agreement (including, without limitation, Section 7.14 of each such agreement), and (ii) until an Event of Default has occurred and is continuing, the Debtor may sell or otherwise dispose of Collateral to the extent not prohibited by the terms of the Credit Agreement or the Term Loan Agreement (including, without limitation, Sections 7.14 and 7.15 of each such agreement), and may grant liens on Collateral to the extent permitted by Sections 4.1 and/or 7.11 of the Credit Agreement and the Term Loan Agreement, provided that a sale, lease or other disposition in the ordinary course of business shall not under any circumstance include a transfer, sale or lease in satisfaction, partial or complete, of a debt owing by such Debtor unless the debt so satisfied is secured with a lien on or ownership right in the goods in question which is prior to the security interest of the Agent therein and is a Permitted Encumbrance under the Credit Agreement and the Term Loan Agreement.

          (d) Each Debtor shall at all times insure the Collateral consisting of tangible personal property against such risks and hazards as other persons or entities similarly situated insure against, and including in any event loss or damage by fire, theft, burglary, pilferage, loss in transit and such other hazards as the Agent may reasonably specify, in amounts and under policies containing loss payable clauses to the Agent as its interest may appear (and, if the Agent requests, naming the Agent and the Secured Creditors as additional insureds therein) and by insurers reasonably acceptable to the Agent, it being agreed that the foregoing shall not preclude any Debtor from directly or indirectly self insuring risks as and to the extent prudent and customary for companies similarly situated and then to the extent permitted by the Credit Agreement and the Term Loan Agreement. All premiums on such insurance shall be paid by the Debtors and, upon the Agent’s request, the policies of such insurance (or certificates therefor) shall be delivered by the Debtors to the Agent. All insurance required hereby shall provide that any loss shall be payable notwithstanding any act or negligence of the relevant Debtor, shall provide that no cancellation thereof shall be effective until at least 30 days after receipt by the relevant Debtor and the Agent of written notice thereof, and shall be reasonably satisfactory to the Agent in all other respects. Each Debtor may retain any proceeds of such insurance arising out of the loss, damage or destruction of the Collateral owned or leased by such Debtor so long as no Event of Default shall have occurred and be continuing or shall arise and be continuing after giving effect to such loss, damage or destruction. After the occurrence and during the continuance of any Event of Default, each Debtor will immediately pay over such proceeds of insurance to the Agent which shall thereafter be applied to the reduction of the Obligations (whether or not then due) or held as collateral security therefore, as the Agent may then determine and as otherwise provided for in the Intercreditor Agreement. All insurance proceeds shall be subject to the lien and security interest of the Agent in the Collateral. Each Debtor hereby authorizes the Agent, at the Agent’s option, to adjust, compromise and settle any losses under any insurance afforded at any time after the occurrence and during the continuance of any Event of Default, and such Debtor does hereby irrevocably constitute the Agent, its officers, agents and

- 7 -

attorneys, in such case as such Debtor’s attorneys-in-fact, with full power and authority to effect such adjustment, compromise and/or settlement and to endorse any drafts drawn by an insurer of the Collateral or any part thereof and to do everything necessary to carry out such purposes and to receive and receipt for any unearned premiums due under policies of such insurance.

          (e) Each Debtor shall, at all reasonable times upon reasonable prior notice, allow the Agent, any Secured Creditor, and their respective representatives free access to and right of inspection of the Collateral during such Debtor’s normal business hours. Upon the occurrence and during the continuance of any Event of Default, the Agent shall have the right to verify all or any part of the Collateral in any manner, and through any medium, which the Agent considers appropriate, and each Debtor agrees to furnish all assistance and information, and perform any acts, which the Agent may reasonably require in connection therewith.

          (f) Each Debtor’s legal name and state of organization is correctly set forth in Schedule A attached hereto. No Debtor has transacted business at any time during the immediately preceding five-year period, and does not currently transact business, under any other legal names or trade names other than the prior legal names and trade names (if any) set forth on Schedule B attached hereto. No Debtor shall change its legal name or transact business under any other trade name without first giving 30 days’ prior written notice of its intent to do so to the Agent.

          (g) Schedule C attached hereto contains a true, complete, and current listing of all copyrights, copyright applications, trademarks, trademark rights, tradenames, patents, patent rights and licenses, patent applications and other intellectual property rights that are owned by the Debtors and are registered with any governmental authority. The relevant Debtor shall promptly notify the Agent in writing of any such additional intellectual property rights acquired or arising after the date hereof, and shall submit to the Agent a supplement to Schedule C attached hereto to reflect such additional rights (provided such Debtor’s failure to do so shall not impair the Agent’s security interest therein). The Debtors own or possess rights to use all franchises, licenses, copyrights, copyright applications, patents, patent rights and licenses, patent applications, trademarks, trademark rights, trade names, trade name rights, copyrights and rights with respect to the foregoing which are required to conduct their business. No event has occurred which permits, or after notice or lapse of time or both would permit, the revocation or termination of any such rights, and no Debtor is liable to any person for infringement under applicable law with respect to any such rights as a result of its business operations.

          (h) Schedule E attached hereto contains a true, complete and current listing of all Commercial Tort Claims held or maintained by the Debtors as of the date hereof for an amount equal to or greater than $1,000,000, each described by reference to the specific incident giving rise to the applicable claim. Each Debtor agrees to execute and deliver to the Agent a supplement to this Agreement in the form attached hereto as Schedule F, or in such other form reasonably acceptable to the Agent, promptly upon becoming aware of any other Commercial Tort Claim in an amount equal to or greater than $1,000,000 held or maintained by any Debtor arising after the date hereof.

- 8 -

          (i) Each Debtor agrees to execute and deliver to the Agent such further agreements, assignments, instruments and documents, and to do all such other things, as the Agent may reasonably deem necessary or appropriate to assure the lien and security interest of the Agent in the Collateral granted hereby, including, without limitation, (i) the execution and delivery of such financing statements and amendments thereof and supplements thereto or other instruments and documents as the Agent may from time to time reasonably require to comply with the UCC and any other applicable law, (ii) the execution and delivery of such patent, trademark and copyright assignment agreements as the Agent may from time to time reasonably require to comply with the filing requirements of the United States Patent and Trademark Office and the United States Copyright Office, and (iii) the execution and delivery of and the use of commercially reasonable efforts to cause the relevant depository institutions, financial intermediaries and letter of credit issuers to execute and deliver such control agreements with respect to all Deposit Accounts, Securities Accounts, Letter-of-Credit Rights and electronic Chattel Paper as the Agent may from time to time reasonably require in accordance with the terms hereof. Each Debtor hereby agrees that a carbon, photographic or other reproduction of this Agreement or any such financing statement is sufficient for filing as a financing statement by the Agent without notice thereof to such Debtor wherever the Agent in its sole discretion desires to file the same. Each Debtor hereby authorizes the Agent to file any and all financing statements covering the Collateral or any part thereof as the Agent may require, including financing statements describing the Collateral as “all assets” or “all personal property” or words of like meaning. The Agent may order lien searches from time to time against any Debtor and the Collateral, and the Debtors shall promptly reimburse the Agent for all reasonable costs and expenses incurred in connection with such lien searches; provided, however, that prior to the occurrence of any Event of Default the Debtors shall not have any obligation to reimburse the Agent for the reasonable costs and expenses of more than one lien search during any calendar year. In the event for any reason the law of any jurisdiction other than Illinois becomes or is applicable to the Collateral or any part thereof, or to any of the Obligations, each Debtor agrees to execute and deliver all such instruments and documents and to do all such other things as the Agent reasonably deems necessary or appropriate to preserve, protect and enforce the security interest of the Agent under the law of such other jurisdiction.

          (j) Upon the occurrence and during the continuance of any Event of Default, on failure of any Debtor to perform any of its covenants and agreements herein contained, the Agent may at its option perform the same and in so doing may expend such sums as the Agent may reasonably deem advisable in the performance thereof, including, without limitation, (i) payment of any insurance premiums, (ii) payment of any taxes, liens and encumbrances, (iii) expenditures made in defending against any adverse claims and (iv) all other expenditures which the Agent may be compelled to make by operation of law or which the Agent may make by agreement or otherwise for the protection of the Collateral. All such sums and amounts so expended shall be repayable by such Debtor immediately without notice or demand, shall constitute additional Obligations secured hereunder, and shall bear interest from the date said amounts are expended at the rate per annum (computed on the basis of a 360-day year for the actual number of days elapsed) equal to the sum of 2% plus the Domestic Rate as from time to time in effect (with any change in such rate per annum as so determined by reason of a change in such Domestic Rate to be effective on the date of such change in said Domestic

- 9 -

Rate) (such rate per annum as so determined being hereinafter referred to as the “Reimbursement Rate”). No such performance of any covenant or agreement by the Agent on behalf of any Debtor, and no such advancement or expenditure therefor, shall relieve any Debtor of any default under the terms of this Agreement or in any way obligate the Agent or any Secured Creditor to take any further or future action with respect thereto. The Agent is hereby authorized to charge any depository or other account of any Debtor maintained with the Agent for the amount of such sums and amounts so expended.

          Section 4. Special Provisions Re: Receivables.

          (a) So long as no Event of Default shall have occurred and be continuing, any merchandise or other goods which are returned by a customer or account debtor to any Debtor or are otherwise recovered by such Debtor, may be resold by such Debtor in the ordinary course of its business in accordance with Section 3(c) hereof; and after the occurrence and during the continuance of any Event of Default, at the request of the Agent, such merchandise and other goods shall be set aside and held by such Debtor as trustee for the Agent and the Secured Creditors and shall remain part of the Collateral. So long as no Event of Default shall have occurred and be continuing, each Debtor may settle and adjust disputes and claims with its customers and account debtors, handle returns and recoveries and grant discounts, credits and allowances, in each case in the ordinary course of its business and otherwise for amounts and on terms which such Debtor considers advisable. However, after the occurrence and during the continuance of any Event of Default, at the request of the Agent, each Debtor shall notify the Agent promptly of all returns and recoveries and shall deliver the merchandise or other returned goods to the Agent. After the occurrence and during the continuance of any Event of Default, at the request of the Agent each Debtor shall also notify the Agent promptly of all disputes and claims and settle or adjust them at no expense to the Agent or the Secured Creditors, but no discount, credit or allowance other than on normal trade terms in the ordinary course of business shall be granted to any customer or account debtor and no returns of merchandise or other goods shall be accepted by any Debtor without the Agent’s consent. The Agent may, at all times after the occurrence and during the continuance of any Event of Default, settle or adjust disputes and claims directly with customers or account debtors for amounts and upon terms which the Agent considers advisable.

          (b) If any Receivable arises out of a contract with the United States of America or any of its departments, agencies or instrumentalities, upon the Agent’s request after the occurrence and during the continuance of an Event of Default, each Debtor agrees to so notify the Agent and execute whatever instruments and documents are reasonably required by the Agent in order that such Receivable shall be assigned to the Agent and that proper notice of such assignment shall be given under the federal Assignment of Claims Act (or any successor statute).

          Section 5. Special Provisions Re: Pledged Notes.

          (a) To the extent any Pledged Note or other item of Collateral is evidenced by an Instrument or Chattel Paper, the applicable Debtor shall cause such Instrument or Chattel Paper to be pledged and delivered to the Agent; provided, however, that, unless (i) an Event of Default shall have occurred and be continuing and (ii) the Agent or the Required Lenders shall have otherwise required, a Debtor shall not be required to deliver any such Instrument or Chattel

- 10 -

Paper if and only so long as (A) the fair market value of any such Instrument or Chattel Paper held by such Debtor is less than $1,000,000 and (B) the aggregate fair market value of all such Instruments or Chattel Paper held by the Borrowers, the Debtors and the other Guarantors and not delivered to the Agent under the Collateral Documents is less than $5,000,000 at any one time outstanding.

          (b) To the extent required to be delivered under Section 5(a) above, the relevant Debtor shall endorse all Instruments and Chattel Paper evidencing a Pledged Note or other item of Collateral in blank and deliver the same to the Agent in a form sufficient to transfer title thereto and shall also duly execute and deliver such other Instruments and Chattel Paper of transfer or assignment as to any other Collateral granted pursuant hereto, all in form and substance reasonably satisfactory to the Agent. To the extent required to be delivered under Section 5(a) above, the relevant Debtor shall deliver to the Agent true and correct copies of all Instruments and Chattel Paper and documents securing each instrument evidencing a Pledged Note or other item of Collateral or setting forth terms and conditions applicable thereto (collectively the “Note Documents”). After the occurrence and during the continuance of an Event of Default, upon request by the Agent, all tangible Chattel Paper and Instruments shall, unless delivered to the Agent or its agent, contain a legend reasonably acceptable to the Agent indicating that such Chattel Paper or Instrument is subject to the security interest of the Agent contemplated by this Agreement; provided, however, that unless the Agent or the Required Lenders shall have required otherwise, a Debtor shall not be required to so legend any such Instrument or Chattel Paper if and only so long as (i) the fair market value of any such Instrument or Chattel Paper held by such Debtor is less than $1,000,000 and (ii) the aggregate fair market value of all such Instruments or Chattel Paper held by the Borrowers, the Debtors and the other Guarantors and not delivered to the Agent under the Collateral Documents is less than $5,000,000 at any one time outstanding.

          (c) After the occurrence and during the continuance of any Event of Default, no Debtor shall, without the prior written consent of the Agent, release any collateral or guarantors for the Pledged Notes or the Note Documents or amend, modify, waive or otherwise take any action which would materially impair the value or collectability of all or any part thereof. At the request of the Agent, each Debtor further agrees to promptly deliver to the Agent copies of all statements, reports and other information and data submitted by any obligor of a Pledged Note to such Debtor.

          (d) Each Debtor hereby authorizes and directs each obligor of a Pledged Note, upon receipt of notice from the Agent that an Event of Default has occurred and is continuing, to make all distributions and payments now due or hereafter to become due to such Debtor in respect of the Pledged Notes or the Note Documents directly to the Agent, and such Debtor agrees that such payments or distributions to the Agent as aforesaid shall be a good receipt and acquittance to such Debtor to the extent so made.

- 11 -

          Section 6. Special Provisions Re: Investment Property and Deposits.

          (a) Unless and until an Event of Default has occurred and is continuing and thereafter until notified to the contrary by the Agent pursuant to Section 10(e) hereof:

          (i) each Debtor shall be entitled to exercise all voting and/or consensual powers pertaining to the Investment Property or any part thereof owned or held by it, for all purposes not inconsistent with the terms of this Agreement, the Credit Agreement, the Term Loan Agreement or any other document evidencing or otherwise relating to any Obligations; and

          (ii) each Debtor shall be entitled to receive and retain all cash dividends paid upon or in respect of the Investment Property owned or held by it.

          (b) Except for equity interests in direct or indirect Subsidiaries, all Investment Property of each Debtor (including all securities, certificated or uncertificated, securities accounts, and commodity accounts but excluding any split-dollar insurance policies) having a fair market value of $1,000,000 or more maintained by such Debtor on the date hereof is listed and identified on Schedule D attached hereto. Each Debtor shall promptly notify the Agent of any other such Investment Property acquired or maintained by such Debtor after the date hereof, and shall submit to the Agent a supplement to Schedule D attached hereto to reflect such additional Investment Property (provided such Debtor’s failure to do so shall not impair the Agent’s security interest therein). Certificates for all certificated securities now or at any time constituting such Investment Property hereunder shall be promptly delivered by the relevant Debtor to the Agent duly endorsed in blank for transfer or accompanied by an appropriate assignment or assignments or an appropriate undated stock power or powers, in every case sufficient to transfer title thereto, and, with respect to any such uncertificated securities or any such Investment Property held by a securities issuer or intermediary, commodity issuer or intermediary, or other issuer or financial intermediary of any kind, the relevant Debtor shall execute and deliver, and shall cause any such issuer or intermediary to execute and deliver, an agreement among such Debtor, the Agent and such issuer or intermediary in form and substance satisfactory to the Agent which provides, among other things, for the issuer’s or intermediary’s agreement that it will comply with such entitlement orders, and apply any value distributed on account of any such Investment Property, as directed by the Agent without further consent by such Debtor at any time after the occurrence and during the continuance of any Event of Default; provided, however, that, unless (i) an Event of Default shall have occurred and be continuing and (ii) the Agent or the Required Lenders shall have otherwise required, a Debtor shall not be required to deliver any such certificates or cause any such agreement to be entered into with the relevant issuer or financial intermediary with respect to (A) Investment Property having a final maturity date not in excess of 90 days from the date the relevant Debtor obtains such Investment Property or (B) other Investment Property if and so long as (x) the fair market value of any such other Investment Property held by such Debtor is less than $1,000,000 and (y) the aggregate fair market value of all such other Investment Property held by the Borrowers, the Debtors and the other Guarantors and not subject to the control (as such term is defined in the UCC) of the Agent under the Collateral Documents is less than $5,000,000 at any one time outstanding. The Agent may at any time after the occurrence and during the continuance of an Event of Default cause to be transferred into its name or the name of its nominee or nominees any and all of the Investment Property hereunder.

- 12 -

          (c) Unless and until an Event of Default has occurred and is continuing, each Debtor may sell or otherwise dispose of any Investment Property to the extent permitted by the Credit Agreement and the Term Loan Agreement. During the existence of any Event of Default, no Debtor shall sell or otherwise dispose of all or any part of the Investment Property without the prior written consent of the Agent.

          (d) Each Debtor represents that on the date of this Agreement, to the best of its knowledge, none of the Investment Property consists of margin stock (as such term is defined in Regulation U of the Board of Governors of the Federal Reserve System) except to the extent such Debtor has delivered to the Agent a duly executed and completed Form U-1 with respect to such margin stock. If at any time the Investment Property or any part thereof consists of margin stock and the relevant Debtor has knowledge of the same, such Debtor shall promptly so notify the Agent and deliver to the Agent a duly executed and completed Form U-1 and such other instruments and documents as (i) are necessary to satisfy the applicable requirements of Regulations T, U and X of the Board of Governors of the Federal Reserve System with respect to such margin stock and (ii) are reasonably requested by the Agent in form and substance reasonably satisfactory to the Agent.

          (e) Notwithstanding anything to the contrary contained herein, in the event any Investment Property is subject to the terms of a separate security agreement (including, without limitation, the Pledge Agreement bearing even date herewith relating to the stock of certain of the Debtors hereunder) in favor of the Agent, the terms of such separate security agreement shall govern and control unless otherwise agreed to in writing by the Agent and the Secured Creditors.

          (f) With respect to any Deposit Account maintained by a depository institution other than the Agent or any Secured Creditor, upon the Agent’s request, the relevant Debtor, the depository institution and the Agent shall, to the extent requested by the Agent, execute and deliver an account control agreement in form and substance satisfactory to the Agent which provides, among other things, for the depository institution’s agreement that it will comply with instructions originated by the Agent directing the disposition of the funds in the Deposit Account without further consent by such Debtor.

          Section 7. Collection of Receivables and Pledged Notes.

          (a) Except as otherwise provided in this Agreement, each Debtor shall make collection of all Receivables and Pledged Notes and may use the same to carry on its business in accordance with sound business practice and otherwise subject to the terms hereof.

          (b) If any Event of Default has occurred and is continuing, in the event the Agent requests a Debtor to do so: (i) all Instruments and Chattel Paper at any time constituting part of the Collateral (including any postdated checks) shall, upon receipt by the relevant Debtor, be immediately endorsed to and deposited with Agent; and/or (ii) such Debtor shall instruct all customers and account debtors and any other obligor of any of the Collateral to remit all payments in respect of the Collateral to a lockbox or lockboxes under the sole custody and control of Agent and which are maintained at post offices selected by the Agent.

          (c) If any Event of Default has occurred and is continuing, the Agent or its designee may notify each Debtor’s customers or account debtors or any other obligor at any time that the Collateral has been assigned to the Agent or that the Agent has a security interest therein, and

either in its own name, or such Debtor’s name, or both, demand, collect (including, without limitation, through a lockbox analogous to that described in Section 7(b)(ii) hereof), receive, receipt for, sue for, compound and give acquittance for any or all amounts due or to become due on the Collateral, and in the Agent’s discretion file any claim or take any other action or proceeding which the Agent may deem reasonably necessary or appropriate to protect and realize upon the security interest of the Agent in the Collateral or any part thereof.

          (d) Any proceeds of Collateral transmitted to or otherwise received by the Agent pursuant to any of the provisions of Sections 7(b) or 7(c) hereof may be handled and administered by the Agent in and through a remittance account or accounts maintained at the Agent or by the Agent at a commercial bank or banks selected by the Agent (each a “Depositary Bank”), and each Debtor acknowledges that the maintenance of such remittance accounts by the Agent is solely for the Agent’s convenience. The Agent need not apply or give credit for any item included in proceeds of Receivables, Pledged Notes or other Collateral until the relevant Depositary Bank has received final payment therefor at its office in cash or final solvent credits current at the site of deposit acceptable to the Agent and the relevant Depositary Bank as such. However, if the Agent does permit credit to be given for any item prior to a Depositary Bank receiving final payment therefor and such Depositary Bank fails to receive such final payment or an item is charged back to the Agent or any Depositary Bank for any reason, the Agent may at its election in either instance charge the amount of such item back against any such remittance account or any depository account of a Debtor maintained with the Agent. Each Debtor hereby indemnifies the Agent and the Secured Creditors from and against all liabilities, damages, losses, actions, claims, judgments, costs, expenses, charges and attorneys’ fees suffered or incurred by the Agent or any Secured Creditor because of the maintenance of the foregoing arrangements; provided, however, that no Debtor shall be required to indemnify the Agent or any Secured Creditor for any of the foregoing to the extent they arise from the negligence or willful misconduct of the person seeking to be indemnified. The Agent and the Secured Creditors shall have no liability or responsibility to any Debtor for the Agent or any other Depositary Bank accepting any check, draft or other order for payment of money bearing the legend “payment in full” or words of similar import or any other restrictive legend or endorsement whatsoever or be responsible for determining the correctness of any remittance.

          Section 8. Special Provisions Re: Inventory and Equipment.

          (a) Each Debtor shall at its own cost and expense maintain, keep and preserve all material portions of the Inventory in good and merchantable condition and keep and preserve all material portions of the Equipment in good repair, working order and condition, ordinary wear and tear excepted, and, without limiting the foregoing, will from time to time make all necessary and proper repairs, replacements and additions to the Equipment so that the overall efficiency of the Equipment taken as a whole shall be fully preserved and maintained.

          (b) Each Debtor warrants and agrees that no Inventory is or will be consigned to any other person or entity without the Agent’s prior written consent.

          (c) At the Agent’s request, each Debtor shall at its own cost and expense cause the lien of the Agent in and to any portion of the Collateral subject to a certificate of title law to be duly noted on such certificate of title or to be otherwise filed in such manner as is prescribed by law in

- 14 -

order to perfect such lien and will cause all such certificates of title and evidences of lien to be deposited with the Agent.

          (d) In the event the Equipment, or any part thereof, is or may be attached to real estate in such a manner that the same may become a fixture, at the Agent’s request after the occurrence and during the continuance of an Event of Default, the relevant Debtor shall take all action reasonably requested by the Agent to maintain the lien and security interest of the Agent in such Collateral at all times fully perfected and in full force and effect, including, without limitation, such fixture financing statements as the Agent may require and, in the event any other person has any right, title or interest in, or lien upon, any such real estate, such Debtor shall use commercially reasonable efforts to cause such person to enter an agreement (i) pursuant to which such person disclaims any right, title and interest in, or lien on, such Equipment, (ii) which allows for the removal of such Equipment by the Agent and (iii) which is otherwise in form and substance reasonably satisfactory to the Agent.

          (e) If any of the Inventory is at any time evidenced by a negotiable document of title, at the Agent’s request after the occurrence and during the continuance of an Event of Default, such document shall be promptly delivered by the relevant Debtor to the Agent.

          Section 9. Power of Attorney. In addition to any other powers of attorney contained herein, each Debtor hereby appoints the Agent, its nominee, or any other person whom the Agent may designate as such Debtor’s attorney-in-fact, with full power after the occurrence and during the continuance of any Event of Default: (i) to sign such Debtor’s name on verifications of Receivables and other Collateral; (ii) to send requests for verification of Collateral to such Debtor’s customers, account debtors and other obligors; (iii) to endorse such Debtor’s name on any checks, notes, acceptances, money orders, drafts and any other forms of payment or security that may come into the Agent’s possession; (iv) to endorse the Collateral in blank or to the order of the Agent or its nominee; (v) to sign such Debtor’s name on any invoice or bill of lading relating to any Collateral, on claims to enforce collection of any Collateral, on notices to and drafts against customers and account debtors and other obligors, on schedules and assignments of Collateral, on notices of assignment and on public records; (vi) to notify the post office authorities to change the address for delivery of such Debtor’s mail to an address designated by the Agent; (vii) to receive and open all mail addressed to such Debtor; and (viii) to do all things necessary to carry out this Agreement. Each Debtor hereby ratifies and approves all acts of any such attorney and agrees that neither the Agent nor any such attorney will be liable for any acts or omissions nor for any error of judgment or mistake of fact or law other than such person’s gross negligence or willful misconduct. The Agent may file one or more financing statements disclosing its security interest in any or all of the Collateral without any Debtor’s signature appearing thereon. Each Debtor also hereby grants the Agent a power of attorney to execute any such financing statements, or amendments and supplements to financing statements, on behalf of such Debtor without prior notice thereof to any Debtor. The foregoing powers of attorney, being coupled with an interest, are irrevocable until the Obligations have been fully paid and satisfied and the commitments of the Secured Creditors to extend credit to or for the account of the Borrowers have expired or otherwise been terminated; provided, however, that the Agent agrees not to exercise the powers of attorney set forth in this Section unless an Event of Default has occurred and is continuing.

- 15 -

          Section 10. Defaults and Remedies.

          (a) The occurrence of any one or more of the following events shall constitute an “Event of Default” hereunder:

          (i) any default in the payment when due (whether by lapse of time, acceleration or otherwise) of the Obligations or any part thereof after giving effect to any applicable notice or grace period; or

          (ii) any representation or warranty made by a Debtor herein, or in any statement or certificate furnished by it pursuant hereto, shall be false in any material respect as of the date of the issuance or making thereof; or

          (iii) any default in the observance or performance of any covenant set forth or otherwise referred to in Section 3(c) hereof or of any provision hereof requiring the maintenance of insurance on the Collateral or dealing with the use or remittance of proceeds of Collateral; or

          (iv) any default in the observance or performance of any other provision hereof which is not remedied within 30 days from the date any Debtor has knowledge of the default; or

          (v) any event occurs or conditions exists which is specified as an “Event of Default” under the Credit Agreement or the Term Loan Agreement.

          (b) During the existence of any Event of Default, the Agent shall have, in addition to all other rights provided herein or by law, the rights and remedies of a secured party under the UCC (regardless of whether the UCC is the law of the jurisdiction where the rights or remedies are asserted and regardless of whether the UCC applies to the affected Collateral), and further the Agent may, without demand and without advertisement, notice, hearing or process of law to the extent permitted by law, all of which each Debtor hereby waives to the extent permitted by law, at any time or times, sell and deliver any or all Collateral held by or for it at public or private sale, at any securities exchange or broker’s board or at any of the Agent’s offices or elsewhere, for cash, upon credit or otherwise, at such prices and upon such terms as the Agent deems advisable, in its sole discretion. Also, if less than all the Collateral is sold, the Agent shall have no duty to marshall or apportion the part of the Collateral sold as between the Debtors, or any of them, but may sell and deliver any or all of the Collateral without regard to which of the Debtors are the owners thereof. In the exercise of any such remedies, the Agent may sell all the Collateral as a unit even though the sales price thereof may be in excess of the amount remaining unpaid on the Obligations. The Agent is authorized at any sale or other disposition of the Collateral or any part thereof, if it deems it advisable so to do, to restrict the prospective bidders or purchasers to persons who will represent and agree that they are purchasing for their own account for investment, and not with a view to the distribution or resale of any of the Collateral. In addition to all other sums due the Agent or any Secured Creditor hereunder, each Debtor shall pay the Agent and the Secured Creditors all reasonable costs and expenses incurred by the Agent and such Secured Creditors, including reasonable attorneys’ fees and court costs, in obtaining, liquidating or enforcing payment of Collateral or the Obligations or in the prosecution or defense of any action or proceeding by or against the Agent, such Secured Creditor or any Debtor

- 16 -

concerning any matter arising out of or connected with this Agreement or the Collateral or the Obligations, including, without limitation, any of the foregoing arising in, arising under or related to a case under the United States Bankruptcy Code (or any successor statute). Any requirement of reasonable notice shall be met if such notice is personally served on or mailed, postage prepaid, to the Debtors in accordance with Section 16(b) hereof at least 10 days before the time of sale or other event giving rise to the requirement of such notice; provided however, that during the existence of any Event of Default, no notification need be given to a Debtor if such Debtor has signed, after the occurrence of such Event of Default, a statement renouncing any right to notification of sale or other intended disposition. The Agent shall not be obligated to make any sale or other disposition of the Collateral regardless of notice having been given. The Agent or any Secured Creditor may be the purchaser at any such sale. Each Debtor hereby waives to the extent permitted by law all of its rights of redemption from any such sale. The Agent may postpone or cause the postponement of the sale of all or any portion of the Collateral by announcement at the time and place of such sale, and such sale may, without further notice, be made at the time and place to which the sale was postponed or the Agent may further postpone such sale by announcement made at such time and place. The Agent has no obligation to prepare the Collateral for sale. The Agent may sell or otherwise dispose of the Collateral without giving any warranties as to the Collateral or any part thereof, including disclaimers of any warranties of title or the like, and each Debtor acknowledges and agrees that the absence of such warranties shall not render the disposition commercially unreasonable.

          (c) Without in any way limiting the foregoing, if any Event of Default has occurred and is continuing, the Agent shall have the right, in addition to all other rights provided herein or by law, to take physical possession of any and all of the Collateral and anything found therein, the right for that purpose to enter without legal process any premises where the Collateral may be found (provided such entry be done lawfully), and the right to maintain such possession on each Debtor’s premises (the Debtors hereby agreeing to lease such premises without cost or expense to the Agent or its designee if the Agent so requests) or to remove the Collateral or any part thereof to such other places as the Agent may desire. If any Event of Default has occurred and is continuing, the Agent shall have the right to exercise any and all rights with respect to all Deposit Accounts of each Debtor, the right to direct the disposition of the funds in each Deposit Account and to collect, withdraw and receive all amounts due or to become due or payable under each such Deposit Account. If any Event of Default has occurred and is continuing, each Debtor shall, upon the Agent’s demand, assemble the Collateral and make it available to the Agent at a place designated by the Agent. If the Agent exercises its right to take possession of the Collateral, each Debtor shall also at its expense perform any and all other steps requested by the Agent to preserve and protect the security interest hereby granted in the Collateral, such as placing and maintaining signs indicating the security interest of the Agent, appointing overseers for the Collateral and maintaining Collateral records.

          (d) Without in any way limiting the foregoing, if any Event of Default has occurred and is continuing, each Debtor hereby grants to the Agent and the Secured Creditors a royalty-free irrevocable license and right to use all of such Debtor’s patents, patent applications, patent licenses, trademarks, trademark registrations, trademark licenses, trade names, trade styles, and similar intangibles in connection with any foreclosure or other realization by the Agent or the Secured Creditors on all or any part of the Collateral, provided that the license granted hereunder shall not include any rights in any license agreement under which the relevant Debtor is licensee which, by its terms, prohibits the license contemplated by this Section 10(d). The license and

- 17 -

right granted the Agent and the Secured Creditors hereby shall be without any royalty or fee or charge whatsoever.

          (e) Without in any way limiting the foregoing, if any Event of Default has occurred and is continuing, all rights of a Debtor to exercise the voting and/or consensual powers which it is entitled to exercise pursuant to Section 6(a)(i) hereof and/or to receive and retain the distributions which it is entitled to receive and retain pursuant to Section 6(a)(ii) hereof, shall, at the option of the Agent, cease and thereupon become vested in the Agent, which, in addition to all other rights provided herein or by law, shall then be entitled solely and exclusively to exercise all voting and other consensual powers pertaining to the Investment Property (including, without limitation, the right to deliver notice of control with respect to any Investment Property held in a securities account or commodity account and deliver all entitlement orders with respect thereto) and/or to receive and retain the distributions which such Debtor would otherwise have been authorized to retain pursuant to Section 6(a)(ii) hereof and shall then be entitled solely and exclusively to exercise any and all rights of conversion, exchange or subscription or any other rights, privileges or options pertaining to any Investment Property as if the Agent were the absolute owner thereof including, without limitation, the rights to exchange, at its discretion, any and all of the Investment Property upon the merger, consolidation, reorganization, recapitalization or other readjustment of the respective issuer thereof or upon the exercise by or on behalf of any such issuer or the Agent of any right, privilege or option pertaining to any Investment Property and, in connection therewith, to deposit and deliver any and all of the Investment Property with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Agent may determine. In the event any of the Collateral shall constitute restricted securities within the meaning of any applicable securities laws, any disposition thereof in compliance with such laws shall not render the disposition commercially unreasonable.

          (f) The powers conferred upon the Agent hereunder are solely to protect its interest in the Collateral and shall not impose on it any duty to exercise such powers. The Agent shall be deemed to have exercised reasonable care in the custody and preservation of the Collateral in its possession or control if such Collateral is accorded treatment substantially equivalent to that which the Agent accords its own property, consisting of similar type assets, it being understood, however, that the Agent shall have no responsibility for ascertaining or taking any action with respect to calls, conversions, exchanges, maturities, tenders or other matters relating to any such Collateral, whether or not the Agent has or is deemed to have knowledge of such matters. This Agreement constitutes an assignment of rights only and not an assignment of any duties or obligations of the Debtors in any way related to the Collateral, and the Agent shall have no duty or obligation to discharge any such duty or obligation. The Agent shall have no responsibility for taking any necessary steps to preserve rights against any parties with respect to any Collateral or initiating any action to protect the Collateral against the possibility of a decline in market value. Neither the Agent nor any party acting as attorney for the Agent shall be liable for any acts or omissions or for any error of judgment or mistake of fact or law other than their gross negligence or willful misconduct.

          (g) Failure by the Agent to exercise any right, remedy or option under this Agreement or any other agreement between any Debtor and the Agent or provided by law, or delay by the Agent in exercising the same, shall not operate as a waiver; and no waiver shall be effective unless it is in writing, signed by the party against whom such waiver is sought to be enforced and

- 18 -

then only to the extent specifically stated. Neither the Agent or any Secured Creditor, nor any party acting as attorney for the Agent or any Secured Creditor, shall be liable hereunder for any acts or omissions or for any error of judgment or mistake of fact or law other than such person’s gross negligence or willful misconduct. The rights and remedies of the Agent and the Secured Creditors under this Agreement shall be cumulative and not exclusive of any other right or remedy which the Agent or the Secured Creditors may have. For purposes of this Agreement, an Event of Default shall be construed as continuing after its occurrence until the same is waived or cured in writing by the Secured Creditors or the Required Lenders, as the case may be, in accordance with the Intercreditor Agreement.

          Section 11. Application of Proceeds. The proceeds and avails of the Collateral at any time received by the Agent during the existence of any Event of Default hereunder shall, when received by the Agent in cash or its equivalent, be applied by the Agent in reduction of, or as collateral security for, the Obligations in accordance with the terms of the Intercreditor Agreement. Each Debtor shall remain liable to the Agent and the Secured Creditors for any deficiency. Any surplus remaining after the full payment and satisfaction of the Obligations shall be returned to the Debtors or to whomsoever the Agent reasonably determines is lawfully entitled thereto.

          Section 12. Continuing Agreement. This Agreement shall be a continuing agreement in every respect and shall remain in full force and effect until all of the Obligations, both for principal and interest, have been fully paid and satisfied and the commitments of the Secured Creditors to extend credit or otherwise make financial accommodations available to (i) the Revolver Borrowers under the Credit Agreement have expired or otherwise been terminated, and (ii) the Company under the Term Loan Agreement have expired or otherwise been terminated. Upon each such termination of this Agreement, the Agent shall, upon the request and at the expense of the Debtors, forthwith release its security interest hereunder.

          Section 13. Primary Security; Obligations Absolute. The lien and security herein created and provided for stand as direct and primary security for the Obligations. No application of any sums received by the Agent in respect of the Collateral or any disposition thereof to the reduction of the Obligations or any portion thereof shall in any manner entitle any Debtor to any right, title or interest in or to the Obligations or any collateral security therefor, whether by subrogation or otherwise, unless and until all Obligations have been fully paid and satisfied and the commitments of the Secured Creditors to extend credit or otherwise make financial accommodations available to the Borrowers, or any one of them, under the Credit Agreement and the Term Loan Agreement have expired or otherwise have been terminated. Each Debtor acknowledges and agrees that the lien and security hereby created and provided for are absolute and unconditional and shall not in any manner be affected or impaired by any acts or omissions whatsoever of the Agent, any Secured Creditor or any other holder of any of the Obligations, and without limiting the generality of the foregoing, the lien and security hereof shall not be impaired by any acceptance by the Agent, any Secured Creditor or any holder of any of the Obligations of any other security for or guarantors upon any of the Obligations or by any failure, neglect or omission on the part of the Agent, any Secured Creditor or any other holder of any of the Obligations to realize upon or protect any of the Obligations or any collateral security therefor. The lien and security hereof shall not in any manner be impaired or affected by (and the Agent and the Secured Creditors, without notice to anyone, are hereby authorized to make from time to time) any sale, pledge, surrender, compromise, settlement, release, renewal, extension,

- 19 -

indulgence, alteration, substitution, exchange, change in, modification or disposition of any of the Obligations, or of any collateral security therefor, or of any guaranty thereof or of any obligor thereon. The Secured Creditors may at their discretion at any time grant credit to the Borrowers, or any of them individually, without notice to any Debtor in such amounts and on such terms as the Secured Creditors may elect without in any manner impairing the lien and security hereby created and provided for. No release, compromise or discharge of any Debtor hereunder or with respect to any of the Obligations or any Collateral provided by such Debtor shall release or discharge, or impair the agreements of, any other Debtor hereunder or in any manner impair the liens and security interests granted by any other Debtor hereunder; and the Agent may proceed against the Collateral provided hereunder by any one or more of the Debtors without proceeding against the other Debtors, their respective properties or any other security or guaranty whatsoever. Without limiting the generality of the foregoing, the requisite number of Secured Creditors (as determined in accordance with the terms of the Intercreditor Agreement) may at any time or from time to time release any Debtor from its obligations hereunder or release any Collateral or effect any compromise with any Debtor, and no such release or compromise shall in any manner impair or otherwise effect the liens granted by, or the obligations of, the other Debtors hereunder. In order to foreclose or otherwise realize hereon and to exercise the rights granted the Agent hereunder and under applicable law, there shall be no obligation on the part of the Agent, any Secured Creditor or any other holder of any of the Obligations at any time to first resort for payment to any Borrower or any other obligor on any of the Obligations or to any guaranty of the Obligations or any portion thereof or to resort to any other collateral security, property, liens or any other rights or remedies whatsoever, and the Agent shall have the right to enforce this instrument irrespective of whether or not other proceedings or steps are pending seeking resort to or realization upon or from any of the foregoing.

          Section 14. The Agent. In acting under or by virtue of this Agreement, the Agent shall be entitled to all the rights, authority, privileges and immunities provided in the Credit Agreement and the Term Loan Agreement, all of which provisions of the Credit Agreement and the Term Loan Agreement (including, without limitation, Section 10 of each such agreement) are incorporated by reference herein with the same force and effect as if set forth herein in their entirety. The Agent hereby disclaims any representation or warranty to the Secured Creditors concerning the perfection of the security interest granted hereunder or in the value of any of the Collateral.

          SECTION 15. PERSONAL JURISDICTION.

          (a) EXCLUSIVE JURISDICTION. EXCEPT AS PROVIDED IN SECTION 15(b), THE AGENT, THE SECURED CREDITORS AND THE DEBTORS 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 STATE OR FEDERAL COURTS LOCATED IN COOK COUNTY, ILLINOIS, BUT EACH OF THE AGENT, THE SECURED CREDITORS AND THE DEBTORS ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF COOK COUNTY, ILLINOIS. EACH OF THE DEBTORS WAIVES IN ALL DISPUTES ANY OBJECTION THAT SUCH DEBTOR MAY HAVE TO THE LOCATION OF THE COURT CONSIDERING THE DISPUTE OR ANY OBJECTION THAT SUCH DEBTOR MAY HAVE THAT ANY OTHER PARTY HAS NOT BEEN JOINED IN SUCH PROCEEDING.

- 20 -

          (b) OTHER JURISDICTIONS. EACH OF THE DEBTORS AGREES THAT THE AGENT AND THE SECURED CREDITORS SHALL HAVE THE RIGHT TO PROCEED AGAINST EACH OF THE DEBTORS OR THEIR COLLATERAL IN A COURT IN ANY LOCATION TO ENABLE THE AGENT OR ANY SECURED CREDITOR TO REALIZE ON THE COLLATERAL, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER ENTERED IN FAVOR OF THE AGENT OR ANY SECURED CREDITOR, WHETHER OR NOT PROCEEDING SEPARATELY AGAINST ANY DEBTOR AND ITS PROPERTY OR JOINTLY AGAINST ANY BORROWER AND ANY ONE OR MORE OF THE DEBTORS AND THEIR PROPERTY. EACH OF THE DEBTORS AGREES THAT IT WILL NOT ASSERT ANY PERMISSIVE COUNTERCLAIMS IN ANY PROCEEDING BROUGHT IN ACCORDANCE WITH THIS PROVISION BY THE AGENT OR ANY SECURED CREDITOR TO REALIZE ON COLLATERAL, OR TO ENFORCE A JUDGMENT OR OTHER COURT ORDER IN FAVOR OF THE AGENT OR ANY SECURED CREDITOR. EACH OF THE DEBTORS WAIVES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE COURT IN WHICH THE AGENT OR ANY SECURED CREDITOR HAS COMMENCED A PROCEEDING DESCRIBED IN THIS SUBSECTION.

          Section 16. Miscellaneous.

          (a) This Agreement cannot be changed or terminated orally. This Agreement shall create a continuing lien on and security interest in the Collateral to the extent set forth herein and shall be binding upon each Debtor and its successors and assigns and shall inure, together with the rights and remedies of the Agent and the Secured Creditors hereunder, to the benefit of the Agent, the Secured Creditors and their successors and assigns; provided, however, that no Debtor may assign its rights or delegate its duties hereunder without the prior written consent of the Agent and the Secured Creditors. Without limiting the generality of the foregoing, and subject to the provisions of the Credit Agreement or the Term Loan Agreement, as the case may be, any Secured Creditor as a lender may assign or otherwise transfer any indebtedness held by it secured by this Agreement to any other person or entity, and such other person or entity shall thereupon become vested with all the benefits in respect thereof granted to such Secured Creditor herein or otherwise.

          (b) Except as otherwise specified herein, all notices hereunder shall be in writing (including, without limitation, notice by telecopy) and shall be given to the relevant party, and shall be deemed to have been made when given to the relevant party, in accordance with Section 8 of the Intercreditor Agreement. All notices to the Debtors hereunder shall be made to the Company, as their agent, in accordance with Section 8 of the Intercreditor Agreement.

          (c) No Secured Creditor shall have the right to institute any suit, action or proceeding in equity or at law for the foreclosure or other realization upon any Collateral subject to this Agreement or for the execution of any trust or power hereof or for the appointment of a receiver, or for the enforcement of any other remedy under or upon this Agreement; it being understood and intended that no one or more of the Secured Creditors shall have any right in any manner whatsoever to affect, disturb or prejudice the lien and security interest of this Agreement by its or their action or to enforce any right hereunder, and that all proceedings at law or in equity shall be instituted, had and maintained by the Agent in the manner herein provided for the benefit of the Secured Creditors.

          (d) In the event that any provision hereof shall be deemed to be invalid or unenforceable by reason of the operation of any law or by reason of the interpretation placed thereon by any court, this Agreement shall be construed as not containing such provision, but

- 21 -

only as to such jurisdictions where such law or interpretation is operative, and the invalidity or unenforceability of such provision shall not affect the validity of any remaining provisions hereof, and any and all other provisions hereof which are otherwise lawful and valid shall remain in full force and effect.

          (e) This Agreement shall be deemed to have been made in the State of Illinois and shall be governed by, and construed in accordance with, the laws of the State of Illinois. The headings in this Agreement are for convenience of reference only and shall not limit or otherwise affect the meaning of any provision hereof.

          (f) This Agreement constitutes an assignment of rights only and not an assignment of any duties or obligations of any Debtor in any way related to the Collateral and that the Agent and the Secured Creditors shall have no duty or obligation to perform or discharge any such duty or obligation.

          (g) In the event the Secured Creditors shall at any time in their discretion permit a substitution of Debtors hereunder or a party shall wish to become Debtor hereunder, such substituted or additional Debtor shall, upon executing an agreement in the form attached hereto as Schedule H, become a party hereto and be bound by all the terms and conditions hereof to the same extent as though such Debtor had originally executed this Agreement and in the case of a substitution, in lieu of the Debtor being replaced. No such substitution shall be effective absent the written consent of the Secured Creditors nor shall it in any manner affect the obligations of the other Debtors hereunder.

          (h) This Agreement may be executed in any number of counterparts and by different parties hereto on separate counterpart signature pages, each constituting an original, but all together one and the same agreement.

          (i) EACH DEBTOR, THE AGENT, AND EACH SECURED CREDITOR HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

          (j) In the event of any inconsistency between this Agreement, the Credit Agreement or the Term Loan Agreement, respectively, the terms of the Credit Agreement or the Term Loan Agreement, as applicable, shall govern.

          (k) Upon the execution and delivery of this Agreement by the Company, the other Debtors and the Agent, this Agreement shall supersede all provisions of the Prior Security Agreement as of such date. Each Debtor hereby agrees that, notwithstanding the execution and delivery of this Agreement, the liens and security interests created and provided for under the Prior Security Agreement continue in effect under and pursuant to the terms of this Agreement for the benefit of all of the Obligations secured hereby. Nothing herein contained shall in any manner affect or impair the priority of the liens and security interests created and provided for by the Prior Security Agreement as to the indebtedness and obligations which would otherwise be secured thereby prior to giving effect to this Agreement.

          WHEREAS, the Borrowers and the other Pledgors may from time to time enter into one or more agreements with respect to interest rate exchange, swap, cap, collar, floor or other similar agreements and one or more foreign currency contracts, currency swap contracts or other similar agreements with one or more of the Revolver Lenders or the Term Loan Lenders, or their affiliates, for the purpose of hedging or otherwise protecting against interest rate and foreign currency exposure (the liability of the Borrowers and the other Pledgors in respect of such interest rate and foreign currency hedging agreements being hereinafter referred to as “Hedging Liability”) (the Revolver Agent, the Term Loan Agent, the Revolver Lenders, the Term Loan Lenders, together with any affiliates of such lenders to whom any Hedging Liability is owed, being hereinafter referred to collectively as the “Secured Creditors” and individually as a “Secured Creditor”);

          WHEREAS, except as indicated on Schedule A attached hereto, the Company owns, directly or indirectly, all or substantially all of the equity interests in each Pledgor (other than the Company), and the Borrowers provide each Pledgor with financial, management, administrative, and technical support which enables such Pledgor to conduct its business in an orderly and efficient manner in the ordinary course; and

          WHEREAS, each Pledgor will benefit, directly and indirectly, from credit and other financial accommodations extended by the Secured Creditors to the Borrowers.

          NOW,THEREFORE, for and in consideration of, among other things, the execution and delivery by the Term Loan Lenders of the Term Loan Agreement, the Revolver Agent, the Term Loan Agent and the Agent of the Intercreditor Agreement, and other good and valuable consideration, receipt whereof is hereby acknowledged, the parties hereto hereby agree as follows:

SECTION 1. TERMS DEFINED IN CREDIT AGREEMENT AND TERM LOAN AGREEMENT.

          All capitalized terms used herein without definition shall have the same meanings herein as such terms have in the Credit Agreement or the Term Loan Agreement, as the context may require. The term “Pledgor” and “Pledgors” as used herein shall mean and include the Pledgors collectively and also each individually, with all grants, representations, warranties and covenants

- 2 -

of and by the Pledgors, or any of them, herein contained to constitute joint and several grants, representations, warranties and covenants of and by the Pledgors; provided, however, that unless the context in which the same is used shall otherwise require, any grant, representation, warranty or covenant contained herein related to the Pledged Securities shall be made by each Pledgor only with respect to the Pledged Securities owned by it or represented by such Pledgor as owned by it.

SECTION 2. GRANT OF SECURITY INTEREST IN THE PLEDGED SECURITIES; OBLIGATIONS SECURED.

          (a) Subject to the terms of the Credit Agreement and the Term Loan Agreement, each Pledgor hereby pledges and deposits with the Agent, and grants to the Agent a security interest in, in each case for the benefit of the Secured Creditors, and acknowledges and agrees that the Agent has and shall continue to have for the benefit of the Secured Creditors a continuing security interest in, any and all right, title and interest of such Pledgor, whether now existing or hereafter acquired or arising, in and to (i) all shares of the capital stock or other equity interests of each Restricted Subsidiary owned or held by such Pledgor, whether now existing or hereafter formed or acquired (those of such shares delivered to and deposited with the Agent concurrently herewith being listed and described on Schedule A as of the date hereof), (ii) all substitutions and additions to such shares or other equity interests, (iii) all dividends, distributions and sums distributable or payable from, upon or in respect of such shares or other equity interests, (iv) all other rights or privileges incident to such shares or other equity interests, and (v) all proceeds and products of any of the foregoing (such shares, equity interests and all other of the foregoing being hereinafter sometimes referred to as the “Pledged Securities”); provided, however, that the Pledged Securities hereunder shall not include any interest held by a Pledgor in the capital stock of any of its Unrestricted Subsidiaries or any of its Foreign Subsidiaries; provided further however that the pledge and security interest created hereby shall remain subject in all respects to the provisions of Section 4.1 of the Credit Agreement and the Term Loan Agreement.

          (b) This Agreement is made and given to secure, and shall secure, the payment and performance of: (i) each of (A) any and all indebtedness, obligations and liabilities of the Borrowers to the Secured Creditors, or any of them individually, evidenced by or otherwise arising out of or relating to the Credit Agreement, the Term Loan Agreement or any promissory note of any Borrower heretofore or hereafter issued under the Credit Agreement or the Term Loan Agreement; (B) any and all obligations of the Revolver Borrowers, or any of them individually, to reimburse the Revolver Agent or any Revolver Lender with respect to any letter of credit or banker’s acceptance issued to or for the account of the Revolver Borrowers, or any of them individually, under the Credit Agreement; (C) any and all obligations of the Borrowers, or any of them individually, to the Secured Creditors, or any of them individually, with respect to Hedging Liability; and (D) any and all liabilities of the Borrowers or the Pledgors, or any of them individually, arising out of any guaranty issued by the Borrowers or the Pledgors, or any of them individually, relating to the foregoing or any part thereof, as well as for any and all other indebtedness, obligations and liabilities of the Borrowers and the Pledgors, or any of them individually, to the Agent or the Secured Creditors, or any of them individually, evidenced by or otherwise arising out of or relating to this Agreement, the Guaranties or any other Loan Document; in each case, whether now existing or hereafter arising (and whether arising before or after the filing of a petition in bankruptcy), due or to become due, direct or indirect, absolute or contingent, and howsoever evidenced, held or acquired, and owing in any currency; and (ii) any

- 3 -

and all expenses and charges, legal or otherwise, suffered or incurred by the Agent or the Secured Creditors, or any of them individually, in collecting or enforcing any of such indebtedness, obligations or liabilities or in realizing on or protecting or preserving any security therefor, including, without limitation, the lien and security interest granted to the Agent in the Pledged Securities hereby (all of the foregoing being hereinafter referred to as the “Obligations”). Notwithstanding anything in this Agreement to the contrary, the right of recovery against any Pledgor under this Agreement shall not exceed $1 less than the lowest amount which would render such Pledgor’s obligations under this Agreement void or voidable under applicable law, including fraudulent conveyance law.

SECTION 3. COVENANTS, REPRESENTATIONS AND WARRANTIES.

          Subject to the terms of the Credit Agreement and the Loan Agreement, each Pledgor hereby covenants and agrees with, and represents and warrants to, the Agent and the Secured Creditors as follows:

          (a) The certificates for all shares of stock, equity interests and other securities owned by each Pledgor (other than securities evidencing an ownership interest in any entity whose total assets are less than or equal to $100,000) in each case to the extent certificated now or at any time constituting the Pledged Securities shall be delivered to the Agent duly endorsed in blank for transfer or accompanied by an appropriate assignment or assignments or an appropriate undated stock power or powers, in every case sufficient to transfer title thereto. The Agent may at any time after the occurrence of an Event of Default and during the continuance thereof cause to be transferred into its name or the name of its nominee or nominees any and all of the Pledged Securities hereunder. The Agent shall at all times have the right to exchange the certificates representing the Pledged Securities for certificates of smaller or larger denominations.

          (b) Each Pledgor is and will be the sole and lawful legal and beneficial owner of all of the Pledged Securities deposited by such Pledgor hereunder. Each Pledgor agrees not to sell, assign, pledge or otherwise dispose of any of such Pledgor’s Pledged Securities or any interest therein except for the security interest granted to the Agent hereunder and liens permitted by Sections 4.1 and 7.11 of the Credit Agreement and the Term Loan Agreement and except for the sale or other disposition of Pledged Securities permitted by the Credit Agreement or the Term Loan Agreement (including, without limitation, Sections 7.14 and 7.15 in each such agreement). In the case of such permitted sale, disposition or dissolution, the Agent shall release the lien upon such Pledged Securities and deliver such Pledged Securities to the relevant Pledgor. The Pledged Securities are and will be free and clear of all security interests, Liens, rights, claims, attachments, levies and encumbrances of every kind, nature and description and whether voluntary or involuntary except for the pledge to the Agent hereunder and for other Liens permitted by the Credit Agreement and the Term Loan Agreement, and each Pledgor will warrant and defend all Pledged Securities which such Pledgor has deposited with the Agent against any claims and demands of all other persons at any time claiming the same or any interest therein adverse to the Agent and the Secured Creditors. Each Pledgor has the right to vote the Pledged Securities (except as set forth herein) and there are no restrictions upon the voting rights associated with, or the transfer of, any of the Pledged

- 4 -

Securities, except as provided by any law applicable to the sale of securities generally or the terms and provisions of this Agreement.

          (c) The Pledged Securities have been validly issued and are fully paid and non-assessable (except for the provisions of Section 630 of the Business Corporation Law of the State of New York as to New York corporations). There are no outstanding commitments or other obligations of the issuers of the Pledged Securities to issue, and no options, warrants or other rights of any individual or entity to acquire, any share of any class or series of capital stock or other equity interests of such issuers. Except otherwise indicated on Schedule A, the Pledged Securities listed and described on Schedule A attached hereto constitute all of the issued and outstanding capital stock or other equity interests of every series and class of each issuer thereof. Each Pledgor further agrees that in the event any such issuer shall issue any additional capital stock of any series or class, each Pledgor will forthwith pledge and deposit hereunder, or cause to be pledged and deposited hereunder, all such additional shares of such capital stock.

          (d) On failure of any Pledgor to perform any of the agreements and covenants herein contained, the Agent may perform the same and in so doing may expend such sums as the Agent may deem advisable in the performance thereof, including without limitation the payment of any taxes, liens and encumbrances, expenditures made in defending against any adverse claim or demand and all other expenditures which the Agent may be compelled to make by operation of law or which Agent may make by agreement or otherwise for the protection of the security hereof. All such sums and amounts so expended shall be due and payable, immediately without notice or demand, shall constitute additional Obligations hereby secured together with interest thereon at the rate per annum (computed on the basis of a year of 360 days) determined by adding 2% to the Domestic Rate from time to time in effect (with any change in such rate per annum as so determined by reason of a change in such Domestic Rate to become effective on the date of such change in said Domestic Rate) (such rate per annum as so determined being hereinafter referred to as the “Reimbursement Rate”). No such performance of any covenant or agreement by the Agent on behalf of such Pledgor, and no such advancement or expenditure therefor, shall relieve such Pledgor of any default under the terms of this Agreement or in any way obligate the Agent or any Secured Creditor to take any further or future action with respect thereto. The Agent is authorized to charge any depository account of any Pledgor maintained with the Agent for the amount of such sums and amounts so expended.

          (e) Each Pledgor represents that this Agreement, together with its delivery to the Agent of the certificates evidencing the Pledged Securities and stock powers therefor, creates a valid security interest securing payment and performance of the Obligations and that no other action is necessary to perfect such security interest. Each Pledgor agrees to execute and deliver to the Agent such further agreements and assignments or other instruments and to do all such other things as the Agent may deem reasonably necessary or appropriate to assure the Agent of such Pledgor’s pledge of the Pledged Securities hereunder.

          (f) If, as and when any Pledgor delivers any securities for pledge hereunder in addition to those listed on Schedule A hereto, the Pledgors shall furnish the Agent a duly

- 5 -

completed and executed amendment to such Schedule in substantially the form (with appropriate insertions) of Schedule B hereto reflecting the securities pledged hereunder after giving effect to such addition.

SECTION 4. VOTING RIGHTS AND DIVIDENDS.

Unless and until an Event of Default hereunder has occurred and is continuing:

          (a) Each Pledgor shall be entitled to exercise all voting and/or consensual powers pertaining to such Pledgor’s Pledged Securities or any part thereof, for all purposes not inconsistent with the terms of this Agreement, the Credit Agreement, the Term Loan Agreement or any other document evidencing or otherwise relating to any Obligations.

          (b) To the extent not prohibited by the terms of the Credit Agreement and the Term Loan Agreement, each Pledgor shall be entitled to receive and retain all dividends and distributions in respect of the Pledged Securities which are paid in cash of whatsoever nature.

          (c) In order to permit each Pledgor to exercise such voting and/or consensual powers which he is entitled to exercise under clause (a) above and to receive such distributions which such Pledgor is entitled to receive and retain under clause (b) above, the Agent shall, if necessary, upon the written request of such Pledgor, from time to time execute and deliver to such Pledgor appropriate proxies and dividend orders.

SECTION 5. POWER OF ATTORNEY.

          Each Pledgor does hereby irrevocably constitute and appoint the Agent its true and lawful attorney, with full power of substitution, for it and in its name, place and stead, to ask, demand, collect, receive, receipt for, sue for, compound and give acquittance for any and all sums or properties which may be or become due, payable or distributable on or in respect of such Pledgor’s Pledged Securities or which constitute a part thereof, with full power to settle, adjust or compromise any claim thereunder or therefor as fully as such Pledgor could itself do, and to endorse or sign the name of such Pledgor on all commercial paper given in payment or in part payment thereof and on all documents of satisfaction, discharge or receipt required or requested in connection therewith, and in the Agent’s discretion, to file any claim or take any other action or proceeding, either in its own name or in the name of such Pledgor, or otherwise, which the Agent may deem necessary or appropriate to collect or otherwise realize upon any and all of such Pledgor’s Pledged Securities, or effect a transfer thereof, or which may be necessary or appropriate to protect and preserve the right, title and interest of the Agent in and to such Pledgor’s Pledged Securities and the security intended to be afforded hereby; provided, however, that the Agent agrees not to exercise the powers of attorney set forth in this Section unless an Event of Default has occurred and is continuing.

- 6 -

SECTION 6. DEFAULTS AND REMEDIES.

          (a) The occurrence of any event or the existence of any condition which is specified as an “Event of Default” under the Credit Agreement or the Term Loan Agreement shall constitute an “Event of Default” hereunder.

          (b) Upon the occurrence and during the continuance of any Event of Default hereunder, all rights of the Pledgors to exercise the voting and/or consensual powers which they are entitled to exercise pursuant to Section 4(a) hereof and/or to receive and retain the distributions which they are entitled to receive and retain pursuant to Section 4(b) hereof, shall, at the option of the Agent, cease and thereupon become vested in the Agent, which, in addition to all other rights provided herein or by law, shall then be entitled solely and exclusively to exercise all voting and other consensual powers pertaining to the Pledged Securities and/or to receive and retain the distributions which the Pledgors would otherwise have been authorized to retain pursuant to Section 4(b) hereof and shall then be entitled solely and exclusively to exercise any and all rights of conversion, exchange or subscription or any other rights, privileges or options pertaining to the Pledged Securities as if the Agent were the absolute owner thereof including, without limitation, the rights to exchange, at its discretion, any and all of the Pledged Securities upon the merger, consolidation, reorganization, recapitalization or other readjustment of the respective issuer thereof or upon the exercise by or on behalf of any such issuer or the Agent of any right, privilege or option pertaining to the Pledged Securities and, in connection therewith, to deposit and deliver any and all of the Pledged Securities with any committee, depositary, transfer agent, registrar or other designated agency upon such terms and conditions as the Agent may determine.

          (c) Upon the occurrence and during the continuance of any Event of Default hereunder, the Agent shall have, in addition to all other rights provided herein or by law, the rights and remedies of a secured party under the Uniform Commercial Code of Illinois in respect to the Pledged Securities (regardless of whether such Uniform Commercial Code is the law of the jurisdiction where the rights or remedies are asserted and regardless of whether such Code applies to the affected Pledged Securities) and further the Agent may, without demand and without advertisement or notice, all of which the Pledgors waive to the extent permitted by law, at any time or times, sell and deliver any or all of the Pledged Securities held by or for it at public or private sale, at any securities exchange or broker’s board or at any of the Agent’s offices or elsewhere, for cash, upon credit or otherwise, at such prices and upon such terms as the Agent deems advisable, in its sole discretion. In the exercise of any such remedies, the Agent may sell all the Pledged Securities as a unit even though the sales price thereof may be in excess of the amount remaining unpaid on the Obligations. Also, if less than all the Pledged Securities are sold, the Agent shall have no duty to marshal or apportion the part of the Pledged Securities so sold as between the Pledgors, or any of them, but may sell and deliver any or all of the Pledged Securities without regard to which of the Pledgors are the owners thereof. The Agent is authorized at any sale or other disposition of the Pledged Securities, if it deems it advisable so to do, to restrict the prospective bidders or purchasers to persons who will represent and agree that they are purchasing for their own account for investment, and not with a view to the distribution or resale of any of the Pledged Securities. The Agent or any Secured Creditor may be the purchaser at any sale or other disposition of the Pledged Securities. The Pledgors hereby waive all of their rights of redemption from any sale or other disposition of the Pledged Securities. Any requirement of reasonable notice shall be met if such notice is personally served on or mailed, postage prepaid, to the Pledgors in accordance with Section 11(h) hereof at least 10 days before

- 7 -

the time of sale or other event giving rise to the requirement of such notice; provided, however, no notification need be given to a Pledgor if such Pledgor has signed, after an Event of Default hereunder has occurred, a statement renouncing any right to notification of sale or other intended disposition. The Agent shall not be obligated to make any sale or other disposition of the Pledged Securities regardless of notice having been given. The Agent may postpone or cause the postponement of the sale of all or any portion of the Pledged Securities by announcement at the time and place of such sale, and such sale may, without further notice, be made at the time and place to which the sale was postponed or the Agent may further postpone such sale by announcement made at such time and place. The proceeds of sale shall be applied first to all costs and expenses of sale, including attorney’s fees and court costs, and second to the payment of the Obligations in accordance with the terms of the Intercreditor Agreement.

          (d) No delay or omission on the part of the Agent in the exercise of any right or remedy hereunder shall operate as a waiver of such right or remedy, nor shall the exercise of any such right or remedy preclude the later or further exercise thereof. All rights or remedies of the Agent on account of the collateral or on account of any of the indebtedness hereby secured, whether arising under this Agreement, any other instrument or document, or at law or in equity, shall be cumulative and not exclusive of each other, and may be exercised by the Agent at such times and in such order as the Agent may determine. The Pledgors agree to pay all costs and expenses (including court costs and reasonable attorney’s fees) incurred by the Agent in enforcing or collecting any of the Obligations secured hereunder, in enforcing any of the terms hereof or in retaking, holding, preparing for sale, selling, collecting or otherwise realizing upon any Pledged Securities, including, without limitation, any of the foregoing arising in, arising under or related to a case under the United States Bankruptcy Code or any successor statute(s) thereto; and all such costs and expenses shall constitute additional Obligations hereby secured which shall be payable on demand together with interest thereon at the Reimbursement Rate. Neither the Agent nor any Secured Creditor, nor any party acting as its attorney, shall be liable for any acts or omissions or for any error of judgment or mistake of fact or law other than such person’s gross negligence or willful misconduct.

SECTION 7. PRIMARY SECURITY; OBLIGATIONS ABSOLUTE.

          The pledge and security herein created and provided for stand as direct and primary security for the Obligations. No application of any sums received by the Agent in respect of the Pledged Securities or any disposition thereof to the reduction of the Obligations or any portion thereof shall in any manner entitle any Pledgor to any right, title or interest in or to the Obligations or any collateral security therefor, whether by subrogation or otherwise, unless and until all Obligations have been fully paid and satisfied and each of the commitments of the Secured Creditors to extend credit or otherwise make financial accommodations available to the Borrowers, or any one of them, under the Credit Agreement and the Term Loan Agreement have expired or otherwise have been terminated. The Pledgors acknowledge and agree that the pledge and security hereby created and provided for are absolute and unconditional and shall not in any manner be affected or impaired by any acts or omissions whatsoever of the Agent, the Secured Creditors or any other holder of any Obligations, and without limiting the generality of the foregoing, the pledge and security hereof shall not be impaired by any acceptance by the Agent, the Secured Creditors or any other holder of any Obligations of any other security for or guarantors upon any Obligations or by any failure, neglect or omission on the part of the Agent, any Secured Creditor or any other holder of any Obligations to realize upon or protect any

- 8 -

Obligations or any collateral security therefor. The pledge and security hereof shall not in any manner be impaired or affected by (and the Agent and the Secured Creditors, without notice to anyone, are hereby authorized to make from time to time) any sale, pledge, surrender, compromise, settlement, release, renewal, extension, indulgence, alteration, substitution, exchange, change in, modification or disposition of any Obligations, or of any collateral security therefor, or of any guaranty thereof, or of the Credit Agreement, or of the Term Loan Agreement or any other instrument or document delivered in connection therewith. The Secured Creditors may at their discretion at any time grant credit to the Borrowers, or any of them, without notice to the Pledgors in such amounts and on such terms as the Secured Creditors may elect without in any manner impairing the pledge and security hereby created and provided for. In order to foreclose or otherwise realize hereon and to exercise the rights granted the Agent hereunder and under applicable law, there shall be no obligation on the part of the Agent or the Secured Creditors or any other holder of any Obligations at any time to first resort for payment to the Borrowers or to any other obligor on any Obligations or to any guaranty of the Obligations or any portion thereof or to resort to any other collateral security, property, liens or any other rights or remedies whatsoever, and the Agent shall have the right to enforce this instrument irrespective of whether or not other proceedings or steps are pending seeking resort to or realization upon or from any of the foregoing.

SECTION 8. APPLICATION OF PROCEEDS.

          The proceeds and avails of the Pledged Securities at any time received by the Agent after the occurrence and during the continuance of any Event of Default hereunder shall, when received by the Agent in cash or its equivalent, be applied by the Agent in reduction of the Obligations as set forth in the Intercreditor Agreement. The Pledgors shall remain liable to the Agent and the Secured Creditors for any deficiency. Any surplus remaining after the full payment and satisfaction of the Obligations shall be returned to the Borrowers on behalf of the Pledgors or to whomsoever a court of competent jurisdiction shall determine to be entitled thereto.

SECTION 9. CONTINUING AGREEMENT.

          This Agreement shall be a continuing agreement in every respect and shall remain in full force and effect until all of the Obligations, both for principal and interest, have been fully paid and satisfied and each of the commitments by the Secured Creditors to extend credit or otherwise make financial accommodations available to the Borrowers under the Credit Agreement and the Term Loan Agreement have expired or otherwise have been terminated. Upon such termination of this Agreement, the Agent shall, upon the request and at the expense of the Pledgors, forthwith release all its liens and security interests hereunder.

SECTION 10. THE AGENT.

          In acting under or by virtue of this Agreement, the Agent shall be entitled to all the rights, authority, privileges and immunities provided in the Credit Agreement and the Term Loan Agreement, all of which provisions of the Credit Agreement and the Term Loan Agreement (including, without limitation, Section 10 of each such agreement) are incorporated by reference herein with the same force and effect as if set forth herein. The Agent hereby disclaims any

- 9 -

representation or warranty to the Secured Creditors concerning the perfection of the security interest granted hereunder or the value of the Pledged Securities.

SECTION 11. MISCELLANEOUS.

          (a) Each Pledgor agrees to pay to the Agent upon demand the cost and expenses incurred by the Agent in connection with the filing of any financing statements or any other steps taken by the Agent in connection with the perfection or protection of such Pledgor’s Pledged Securities hereunder and in connection with releasing such pledge and security interest herein granted and provided for upon termination hereof.

          (b) No waiver or modification or amendment to the terms of this Agreement shall be effective as against the Agent and the Secured Creditors unless the same is in writing and signed by an officer of the Agent. No such waiver, modification or amendment shall in any way affect any of the rights or remedies of the Agent and the Secured Creditors hereunder except to the extent that such waiver, modification or amendment specifically provides.

          (c) This Agreement and all of the rights, privileges, remedies and options given to the Agent and the Secured Creditors hereunder and in and to any of the Pledged Securities hereunder shall inure to the benefit of the Agent and the Secured Creditors and their successors and assigns; and all the terms, conditions, promises, covenants, representations and warranties of and in this Agreement shall bind each Pledgor and its successors and assigns, provided that no Pledgor may assign its rights or delegate its duties hereunder without the Agent’s prior written consent.

          (d) In the event that any provision hereof shall be deemed to be invalid by reason of the operation of any law or by reason of the interpretation placed thereon by any court, this Agreement shall be construed as not containing such provision, but only as to such locations where such law or interpretation is operative, and the invalidity of such provision shall not affect the validity of any remaining provision hereof, and any and all other provisions hereof which are otherwise lawful and valid shall remain in full force and effect.

          (e) No Secured Creditor shall have the right to institute any suit, action or proceeding in equity or at law for the enforcement of any remedy under or upon this Agreement; it being understood and intended that no one or more of the Secured Creditors shall have any right in any manner whatsoever to affect, disturb or prejudice the lien of this Agreement by its or their action or to enforce any right hereunder, and that all proceedings at law or in equity shall be instituted, had and maintained by the Agent in the manner herein provided and for the benefit of the Secured Creditors.

          (f) This Agreement shall be deemed to have been made in the State of Illinois. This Agreement and all rights and obligations hereunder, including matters of construction, validity and performance shall be governed by the internal laws of the State of Illinois. All terms which are used in this Agreement which are defined in the Uniform Commercial Code of Illinois shall have the same meanings herein as said terms do in such Uniform Commercial Code unless this Agreement shall otherwise specifically provide. The headings in this instrument are for convenience of reference only and shall not limit or otherwise affect the meaning of any provision hereof.

- 10 -

          (g) This Agreement may be executed in any number of counterparts, each constituting an original, but all together one and the same instrument. Each Pledgor acknowledges that this Agreement is and shall be effective upon its execution and delivery by such Pledgor to the Agent, and it shall not be necessary for the Agent to execute this Agreement or any other acceptance hereof or otherwise to signify or express its acceptance hereof.

          (h) Except as otherwise specified herein, all notices hereunder shall be in writing (including, without limitation, notice by telecopy) and shall be given to the relevant party, and shall be deemed to have been made when given to the relevant party, in accordance with Section 8 of the Intercreditor Agreement. All notices to the Pledgors hereunder shall be made to the Company, as their agent, in accordance with Section 8 of the Intercreditor Agreement.

          (i) In the event the Secured Creditors shall at any time in their discretion permit a substitution of Pledgors hereunder or a party shall wish to become a Pledgor hereunder, such substituted or additional Pledgor shall, upon executing an agreement in the form attached hereto as Schedule C, become a party hereto and be bound by all the terms and conditions hereof to the same extent as though such Pledgor had originally executed this Agreement and, in the case of a substitution, in lieu of the Pledgor being replaced. No such substitution shall be effective absent the written consent of Secured Creditors nor shall it in any manner affect the obligations of the other Debtors hereunder.

          (j) JURY TRIAL WAIVER. EACH PLEDGOR, THE AGENT, AND EACH SECURED CREDITOR HEREBY IRREVOCABLY WAIVES ANY AND ALL RIGHT TO TRIAL BY JURY IN ANY LEGAL PROCEEDING ARISING OUT OF OR RELATING TO THIS AGREEMENT OR THE TRANSACTIONS CONTEMPLATED HEREBY.

EXCEPT AS PROVIDED IN SUBSECTION (ii), EACH PLEDGOR, THE AGENT AND THE SECURED CREDITORS AGREE THAT ALL DISPUTES BETWEEN THEM ARISING OUT OF, CONNECTED WITH, RELATED TO, OR INCIDENTAL TO THE RELATIONSHIP ESTABLISHED BETWEEN THEM IN CONNECTION WITH THIS AGREEMENT, AND WHETHER ARISING IN CONTRACT, TORT, EQUITY, OR OTHERWISE, SHALL BE RESOLVED ONLY BY STATE OR FEDERAL COURTS LOCATED IN COOK COUNTY, ILLINOIS, BUT EACH OF THE PLEDGORS, THE AGENT AND THE SECURED CREDITORS ACKNOWLEDGE THAT ANY APPEALS FROM THOSE COURTS MAY HAVE TO BE HEARD BY A COURT LOCATED OUTSIDE OF COOK COUNTY, ILLINOIS. EACH PLEDGOR WAIVES IN ALL DISPUTES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE COURT CONSIDERING THE DISPUTE.

          (ii) OTHER JURISDICTIONS.

EACH PLEDGOR WAIVES ANY OBJECTION THAT IT MAY HAVE TO THE LOCATION OF THE COURT IN WHICH THE AGENT OR ANY SECURED CREDITOR HAS COMMENCED A PROCEEDING DESCRIBED IN THIS SUBSECTION.

- 11 -

          (l) In the event of any inconsistency between this Agreement, the Credit Agreement or the Term Loan Agreement, respectively, the terms of the Credit Agreement or the Term Loan Agreement, as applicable, shall govern.

SCHEDULE B

AMENDMENT TO SECOND AMENDED AND RESTATED PLEDGE AGREEMENT

          Reference is hereby made to that certain Second Amended and Restated Pledge Agreement dated as of September _, 2007, as heretofore amended (the “Pledge Agreement”), from the Pledgors signatory thereto to Harris N.A. (“Harris”), as collateral agent for the Secured Creditors (Harris acting as such collateral agent and any successor or successors to Harris in such capacity being hereinafter referred to as the “Agent”). Capitalized terms not otherwise defined herein shall have the meaning set forth in the Pledge Agreement.

          Subsequent to the Pledgors’ delivery of the Pledge Agreement, certain shares of stock have been added as Pledged Securities under the Pledge Agreement. As a result of such addition, Schedule A of the Pledge Agreement does not accurately describe the shares of capital stock currently held by the Agent as collateral under the Pledge Agreement.

          The Pledgors now desire to amend Schedule A to the Pledge Agreement to reflect such addition, and this instrument shall constitute an agreement between the Pledgors and the Agent amending the Pledge Agreement in the respects, but only in the respects, hereinafter set forth:

          1. Schedule A of the Pledge Agreement shall be and hereby is amended and as so amended shall be restated in its entirety to read as Annex A attached hereto.

          2. As collateral security for the Obligations, each Pledgor hereby grants to the Agent a continuing security interest in, and acknowledges and agrees that the Agent has and shall continue to have a continuing security interest in, all the shares of capital stock of each issuer listed and described on Annex A attached hereto and all the other properties, rights, interests and privileges comprising the Pledged Securities (as such term is defined in the Pledge Agreement after giving effect to this Amendment), to the same extent and with the same force and effect as if the shares of stock described on Annex A had originally been included on Schedule A to the Pledge Agreement. The foregoing granting clause is in addition to and supplemental of and not in substitution for the granting clause contained in the Pledge Agreement. Neither the Pledgors nor the Agent intend by this Amendment to in any way impair or otherwise affect the lien of the Pledge Agreement on such of the Pledged Securities which were subject to the Pledge Agreement prior to giving effect to this Amendment.

          3. Each Pledgor hereby repeats and reaffirms all of its covenants, agreements, representations and warranties contained in the Pledge Agreement, each and all of which shall be applicable to all of the stock and other properties, rights, interests and privileges subject to the lien of the Pledge Agreement after giving effect to this Amendment. Each Pledgor hereby certifies that no Event of Default or event which, with notice or lapse of time or both, would constitute an Event of Default exists under the Pledge Agreement after giving effect to this Amendment.

          4. No reference to this Amendment need be made in any note, instrument or other document at any time referring to the Pledge Agreement, any reference in any of such to the Pledge Agreement to be deemed to reference to the Pledge Agreement as modified hereby. All references in the Pledge Agreement to the term “Pledged Securities” shall be deemed a reference to such term as defined in the Pledge Agreement after giving effect to this Amendment.

          5. Except as specifically modified hereby, all the terms and conditions of the Pledge Agreement shall stand and remain unchanged and in full force and effect. This Amendment shall be effective upon the Pledgors’ execution and delivery thereof to the Agent, no acceptance by the Agent being required.

(“Harris”), as collateral agent for the Secured Creditors (defined in the Pledge Agreement hereinafter identified and defined) (Harris acting as such collateral agent and any successor or successors to Harris in such capacity being hereinafter referred to as the “Agent”);

WITNESSETH  THAT:

          WHEREAS, EMCOR Group, Inc. and certain other parties have executed and delivered to the Agent that certain Second Amended and Restated Pledge Agreement dated as of September ___, 2007 or supplements thereto (such Second Amended and Restated Pledge Agreement, as the same may from time to time be modified or amended, including supplements thereto which add additional parties as Pledgors thereunder, being hereinafter referred to as the “Pledge Agreement”) pursuant to which such parties (the “Existing Pledgors”) have granted to the Agent for the benefit of the Secured Creditors a lien on and security interest in such Existing Pledgors’ Pledged Securities (as such term is defined in the Pledge Agreement) to secure the Obligations (as such term is defined in the Pledge Agreement) of the Borrowers referred to therein owing to the Agent and the Secured Creditors arising out of or related to the Credit Agreement and the Term Loan Agreement referred to therein; and

          WHEREAS, the Borrowers provide the New Pledgor with substantial financial, managerial, administrative, technical and design support and the New Pledgor will directly and substantially benefit from credit and other financial accommodations extended and to be extended by the Secured Creditors to the Borrowers;

          NOW, THEREFORE, FOR VALUE RECEIVED, and in consideration of advances made or to be made, or credit accommodations given or to be given, to the Borrowers by the Secured Creditors from time to time, the New Pledgor hereby agrees as follows:

          1. The New Pledgor acknowledges and agrees that it shall become a “Pledgor” party to the Pledge Agreement effective upon the date the New Pledgor’s execution of this Agreement and the delivery of this Agreement to the Agent, and that upon such execution and delivery, all references in the Pledge Agreement to the terms “Pledgor” or “Pledgors” shall be deemed to include the New Pledgor. Without limiting the generality of the foregoing, the New Pledgor hereby repeats and reaffirms all grants (including the grant of a lien and security interest), covenants, agreements, representations and warranties contained in the Pledge Agreement as amended hereby, each and all of which are and shall remain applicable to the Pledged Securities from time to time owned by the New Pledgor or in which the New Pledgor from time to time has any rights. Without limiting the foregoing, in order to secure payment of the Obligations, whether now existing or hereafter arising, the New Pledgor does hereby grant to the Agent for the benefit of the Secured Creditors, and hereby agrees that the Agent has and shall continue to

have for the benefit of the Secured Creditors a continuing security interest in, among other things, all of the New Pledgor’s Pledged Securities (as such term is defined in the Pledge Agreement) described in, and subject to the limitations set forth in, Section 2 of the Pledge Agreement, each and all of such granting clauses being incorporated herein by reference with the same force and effect as if set forth in their entirety except that all references in such clauses to the Existing Pledgor or any of them shall be deemed to include references to the New Pledgor. Nothing contained herein shall in any manner impair the priority of the liens and security interests heretofore granted in favor of the Agent under the Pledge Agreement.

          2. The New Pledgor hereby acknowledges and agrees that the Obligations are secured by all of the Pledged Securities according to, and otherwise on and subject to, the terms and conditions of the Pledge Agreement to the same extent and with the same force and effect as if the New Pledgor had originally been one of the Existing Pledgors under the Pledge Agreement and had originally executed the same as such an Existing Pledgor.

          3. All capitalized terms used in this Agreement without definition shall have the same meaning herein as such terms have in the Pledge Agreement, except that any reference to the term “Pledgor” or “Pledgors” and any provision of the Pledge Agreement providing meaning to such term shall be deemed a reference to the Existing Pledgors and the New Pledgor. Except as specifically modified hereby, all of the terms and conditions of the Pledge Agreement shall stand and remain unchanged and in full force and effect.

          4. The New Pledgor agrees to execute and deliver such further instruments and documents and do such further acts and things as the Agent may reasonably deem necessary or proper to carry out more effectively the purposes of this Agreement.

          5. No reference to this Agreement need be made in the Pledge Agreement or in any other document or instrument making reference to the Pledge Agreement, any reference to the Pledge Agreement in any of such to be deemed a reference to the Pledge Agreement as modified hereby.

          6. This Agreement shall be governed by and construed in accordance with the State of Illinois (without regard to principles of conflicts of law).

EXHIBIT 4.1(d)

GUARANTY AGREEMENT

          This Guaranty Agreement (the “Guaranty”) is dated as of September 19, 2007, by the parties executing this Guaranty under the heading “Guarantors” (such parties, along with any other parties who execute and deliver to the Agent hereinafter identified and defined an agreement in the form attached hereto as Exhibit A, being hereinafter referred to collectively as the “Guarantors” and individually as a “Guarantor”) in favor of the Guaranteed Creditors referred to below.

WITNESSETH:

          WHEREAS, EMCOR Group, Inc., a Delaware corporation (the “Borrower”), Bank of Montreal (“BMO”), individually as a lender and as administrative agent (BMO, in such capacity as administrative agent, hereinafter referred to as the “Agent”) and certain other lenders have entered into a Term Loan Agreement dated as of September 19, 2007 (such Term Loan Agreement, as the same may be amended, modified or restated from time to time, being hereinafter referred to as the “Loan Agreement”), pursuant to which BMO and such other lenders from time to time party thereto (BMO, in its individual capacity, and such other lenders which are now or which from time to time hereafter become party to the Loan Agreement being hereinafter referred to collectively as the “Lenders” and individually as a “Lender”) have agreed, subject to certain terms and conditions, to make a term loan and make certain other financial accommodations available to the Borrower;

          WHEREAS, as a condition precedent to making the term loan or otherwise making financial accommodations available to the Borrower under the Loan Agreement, the Lenders have required, among other things, that the Guarantors guarantee the payment and performance of the Borrower’s obligations and liabilities arising under or otherwise relating to the Loan Agreement and, in that regard, that the Guarantors execute and deliver this Guaranty in favor of the Agent and the Lenders (the Agent and the Lenders together with any affiliates of the Lenders to whom any Hedging Liability (each as defined below) is owed being hereinafter referred to collectively as the “Guaranteed Creditors” and individually as a “Guaranteed Creditor”);

          WHEREAS, the Borrower and the other Guarantors may from time to time enter into one or more agreements with respect to interest rate exchange, swap, cap, collar, floor or other similar agreements and one or more foreign currency contracts, currency swap contracts or other similar agreements with one or more of the Lenders, or their affiliates, for the purpose of hedging or otherwise protecting against interest rate and foreign currency exposure (the liability of the Borrower and the Guarantors in respect of such interest rate and foreign currency hedging agreements being hereinafter referred to as “Hedging Liability”);

          WHEREAS, the Borrower owns, directly or indirectly, all or substantially all of the equity interests in each Guarantor, and the Borrower provides each Guarantor with financial, management, administrative, and technical support which enables such Guarantor to conduct its business in an orderly and efficient manner in the ordinary course; and

          WHEREAS, each Guarantor will benefit, directly and indirectly, from credit and other financial accommodations extended by the Lenders to the Borrower.

          NOW, THEREFORE, FOR VALUE RECEIVED, and in consideration of advances made or to be made, or credit accommodations given or to be given, to the Borrower by the Lenders from time to time, each Guarantor hereby makes the following representations and warranties to the Guaranteed Creditors, and hereby covenants and agrees with the Guaranteed Creditors, as follows:

          1. All capitalized terms used herein without definition shall have the same meanings herein as such terms have in the Loan Agreement.

          2. Each Guarantor hereby jointly and severally guarantees to the Guaranteed Creditors, the due and punctual payment of (i) any and all indebtedness, obligations and liabilities of the Borrower owing to the Guaranteed Creditors, or any of them individually, evidenced by or otherwise arising out of or relating to the Loan Agreement, any promissory note of the Borrower heretofore or hereafter issued under the Loan Agreement, all obligations of the Borrower and the Guarantors to the Guaranteed Creditors, and to any of them individually, with respect to Hedging Liability, and any liability of the Borrower arising out of any guaranty issued by it relating to the foregoing or any part thereof, as well as for any and all other indebtedness, obligations and liabilities of the Borrower and the Guarantors, or any of them individually, to the Guaranteed Creditors, or any of them individually, evidenced by or otherwise arising out of or relating to any other Loan Document, in each case, whether now existing or hereafter arising (and whether arising before or after the filing of a petition in bankruptcy), due or to become due, direct or indirect, absolute or contingent, and howsoever evidenced, held or acquired, and owing in any currency, and (ii) any and all expenses and charges, legal or otherwise, suffered or incurred by the Guaranteed Creditors, or any of them individually, in collecting or enforcing any of such indebtedness, obligations or liabilities or in realizing on or protecting or preserving any security therefor (all of the foregoing hereinafter referred to as the “indebtedness hereby guaranteed”). In case of failure by the Borrower punctually to pay any indebtedness hereby guaranteed, each Guarantor hereby jointly and severally agrees to make such payment or to cause such payment to be made punctually as and when the same shall become due and payable, whether at stated maturity, by acceleration or otherwise, and as if such payment were made by the Borrower.

          3. Each Guarantor further jointly and severally agrees to pay all expenses, legal and/or otherwise (including court costs and reasonable attorneys’ fees), paid or incurred by any Guaranteed Creditor in endeavoring to collect the indebtedness hereby guaranteed, or any part thereof, and in protecting, defending or enforcing this Guaranty in any litigation, bankruptcy or insolvency proceedings or otherwise.

          4. Until the indebtedness hereby guaranteed is paid and satisfied in full and each of the commitments by the Guaranteed Creditors to extend any indebtedness hereby guaranteed have expired or otherwise have terminated, each Guarantor agrees that, upon demand, such Guarantor will then pay to the Agent for the benefit of the Guaranteed Creditors the full amount of the indebtedness hereby guaranteed whether or not any proceedings or steps are pending seeking payment of the indebtedness hereby guaranteed from any one or more of the other Guarantors.

-2-

          5. Each Guarantor agrees that such Guarantor will not exercise or enforce any right of exoneration, contribution, reimbursement, recourse or subrogation available to such Guarantor against any person liable for payment of the indebtedness hereby guaranteed, or as to any security therefor, unless and until the full amount owing to the Guaranteed Creditors of the indebtedness hereby guaranteed has been fully paid and satisfied and each of the commitments by the Guaranteed Creditors to extend any indebtedness hereby guaranteed to the Borrower shall have expired or otherwise shall have terminated. The payment by any Guarantor of any amount or amounts to the Guaranteed Creditors pursuant hereto shall not in any wise entitle any such Guarantor, either at law, in equity or otherwise, to any right, title or interest (whether by way of subrogation or otherwise) in and to the indebtedness hereby guaranteed or any part thereof or any collateral security therefor or any other rights or remedies in any way relating thereto or in and to any amounts theretofore, then or thereafter paid or applicable to the payment thereof howsoever such payment may be made and from whatsoever source such payment may be derived unless and until all of the indebtedness hereby guaranteed and all costs and expenses suffered or incurred by the Guaranteed Creditors in enforcing this Guaranty have been paid and satisfied in full and each of the commitments by the Guaranteed Creditors to extend any indebtedness hereby guaranteed to the Borrower shall have expired or otherwise shall have terminated and unless and until such payment in full and termination, any payments made by any Guarantor hereunder and any other payments from whatsoever source derived on account of or applicable to the indebtedness hereby guaranteed or any part thereof shall be held and taken to be merely payments in gross to the Guaranteed Creditors reducing pro tanto the indebtedness hereby guaranteed.

          6. To the extent permitted by the Loan Agreement, each Guaranteed Creditor may, without any notice whatsoever to any of the Guarantors, sell, assign, or transfer all of the indebtedness hereby guaranteed, or any part thereof, or grant participations therein, and in that event each and every immediate and successive assignee, transferee, or holder of all or any part of the indebtedness hereby guaranteed, shall have the right through the Agent pursuant to Section 19 hereof to enforce this Guaranty, by suit or otherwise, for the benefit of such assignee, transferee, or holder as fully as if such assignee, transferee, or holder were herein by name specifically given such rights, powers and benefits; but each Guaranteed Creditor through the Agent pursuant to Section 19 hereof shall have an unimpaired right to enforce this Guaranty for its own benefit, as to so much of the indebtedness hereby guaranteed that it has not sold, assigned or transferred.

          7. This Guaranty is a continuing, absolute and unconditional Guaranty, and shall remain in full force and effect until written notice of its discontinuance executed by the Borrower and all the Guarantors shall be actually received by the Guaranteed Creditors, and also until any and all of the indebtedness hereby guaranteed which was created or existing before receipt of such notice shall be fully paid and satisfied and each of the commitments by the Guaranteed Creditors to extend any indebtedness hereby guaranteed to the Borrower shall have expired or otherwise shall have terminated. The dissolution of any Guarantor shall not terminate this Guaranty as to such Guarantor until notice of such dissolution shall have been actually received by the Guaranteed Creditors, nor until all of the indebtedness hereby guaranteed, created or existing or committed to be extended in each case before receipt of such notice shall be fully paid and satisfied. The Guaranteed Creditors may at any time or from time to time release any Guarantor from its obligations hereunder or effect any compromise with any Guarantor and no such release or compromise shall in any manner impair or otherwise affect the obligations

hereunder of the other Guarantors. The Guaranteed Creditors shall release a Guarantor from its obligations hereunder upon a sale of all the outstanding capital stock owned by the Borrower and any Subsidiary as permitted by Sections 7.14 or 7.15 of the Loan Agreement.

In case of the dissolution, liquidation (except as permitted by the Loan Agreement) or insolvency (howsoever evidenced) of, or the institution of bankruptcy or receivership proceedings against, the Borrower or any Material Restricted Subsidiary, all of the indebtedness hereby guaranteed which is then existing shall, at the option of the Lenders (as determined in accordance with the terms of the Loan Agreement), immediately become due or accrued and payable from the Material Restricted Subsidiary. All payments received from the Borrower or on account of the indebtedness hereby guaranteed from whatsoever source, shall be taken and applied as payment in gross, and this Guaranty shall apply to and secure any ultimate balance that shall remain owing to the Guaranteed Creditors.

          9. The liability hereunder shall in no way be affected or impaired by (and the Guaranteed Creditors are hereby expressly authorized to make from time to time, without notice to any of the Guarantors) any sale, pledge, surrender, compromise, settlement, release, renewal, extension, indulgence, alteration, substitution, exchange, change in, modification or other disposition of any of the indebtedness hereby guaranteed, either express or implied, or of any Loan Document or any other contract or contracts evidencing any thereof, or of any security or collateral therefor or any guaranty thereof. The liability hereunder shall in no way be affected or impaired by any acceptance by the Guaranteed Creditors of any security for or other guarantors upon any of the indebtedness hereby guaranteed, or by any failure, neglect or omission on the part of the Guaranteed Creditors to realize upon or protect any of the indebtedness hereby guaranteed, or any collateral or security therefor, or to exercise any lien upon or right of appropriation of any moneys, credits or property of the Borrower, possessed by the Guaranteed Creditors, toward the liquidation of the indebtedness hereby guaranteed, or by any application of payments or credits thereon. The Guaranteed Creditors shall have the exclusive right to determine how, when and what application of payments and credits, if any, shall be made on said indebtedness hereby guaranteed, or any part of same. In order to hold any Guarantor liable hereunder, there shall be no obligation on the part of the Guaranteed Creditors at any time, to resort for payment to the Borrower or to any other Guarantor, or to any other person or entity, their properties or estate, or resort to any collateral, security, property, liens or other rights or remedies whatsoever, and the Guaranteed Creditors shall have the right to enforce this Guaranty against any Guarantor irrespective of whether or not other proceedings or steps are pending seeking resort to or realization upon or from any of the foregoing.

          10. In the event the Guaranteed Creditors shall at any time in their discretion permit a substitution of Guarantors hereunder or a party shall wish to become Guarantor hereunder, such substituted or additional Guarantor shall, upon executing an agreement in the form attached hereto as Exhibit A, become a party hereto and be bound by all the terms and conditions hereof to the same extent as though such Guarantor had originally executed this Guaranty and, in the case of a substitution, in lieu of the Guarantor being replaced. No such substitution shall be effective absent the written consent of the Guaranteed Creditors nor shall it in any manner affect the obligations of the other Guarantors hereunder.

-4-

          11. All diligence in collection or protection, and all presentment, demand, protest and/or notice, as to any and everyone, whether or not the Borrower or the Guarantors or others, of dishonor and of default and of non-payment and of the creation and existence of any and all of said indebtedness hereby guaranteed, and of any security and collateral therefor, and of the acceptance of this Guaranty, and of any and all extensions of credit and indulgence hereunder, are expressly waived.

          12. No act of commission or omission of any kind, or at any time, upon the part of the Guaranteed Creditors in respect to any matter whatsoever, shall in any way affect or impair this Guaranty.

          13.

The Guarantors agree that the Guarantors shall be and remain jointly and severally liable for any deficiency remaining after foreclosure or other realization on any lien or security interest securing the indebtedness hereby guaranteed, whether or not the liability of the Borrower or any other obligor for such deficiency is discharged pursuant to statute or judicial decision.

          14. If any payment applied by the Guaranteed Creditors to the indebtedness hereby guaranteed is thereafter set aside, recovered, rescinded or required to be returned for any reason (including, without limitation, the bankruptcy, insolvency or reorganization of the Borrower or any other obligor), the indebtedness hereby guaranteed to which such payment was applied shall for the purposes of this Guaranty be deemed to have continued in existence, notwithstanding such application, and this Guaranty shall be enforceable as to such of the indebtedness hereby guaranteed as fully as if such application had never been made.

          15. The liability of the Guarantors under this Guaranty is in addition to and shall be cumulative with all other liabilities of the Guarantors after the date hereof to the Guaranteed Creditors as a Guarantor of the indebtedness hereby guaranteed, without any limitation as to amount, unless the instrument or agreement evidencing or creating such other liability specifically provides to the contrary.

          16. Any invalidity or unenforceability of any provision or application of this Guaranty shall not affect other lawful provisions and applications hereof, and to this end the provisions of this Guaranty are declared to be severable. Without limiting the generality of the foregoing, any invalidity or unenforceability against any Guarantor of any provision or application of the Guaranty shall not affect the validity or enforceability of the provisions or application of this Guaranty as against the other Guarantors.

          17. Notwithstanding anything herein to the contrary, the right of recovery against any Guarantor under this Guaranty shall not exceed $l less than the lowest amount which would

-5-

render such Guarantor’s obligations under this Guaranty void or voidable under applicable law, including fraudulent conveyance law.

          18. Any demand for payment on this Guaranty or any other notice required or desired to be given hereunder to any Guarantor shall be deemed to have been validly served, given or delivered to such Guarantor when given to such Guarantor or when given to the Borrower in accordance with the Loan Agreement.

          19. No Guaranteed Creditor shall have the right to institute any suit, action or proceeding in equity or at law in connection with this Guaranty for the enforcement of any remedy under or upon this Guaranty; it being understood and intended that no one or more of the Guaranteed Creditor shall have any right in any manner whatsoever to enforce any right hereunder, and that all proceedings at law or in equity shall be instituted, had and maintained by the Agent in the manner herein provided and for the benefit of the Guaranteed Creditor.
