7.625% Senior Notes due 2018

On October 20, 2010, the Company completed a private placement offering of $300 million in aggregate principal amount of its 7.625% senior unsecured notes due November 1, 2018 (the “Senior Notes”). The Senior Notes were priced at 99.258%, resulting in a yield to maturity of 7.75%. The Senior Notes were made available in a private offering that is exempt from the registration requirements of the Securities Act of 1933, as amended (the “Securities Act”). The private placement of the Senior Notes resulted in proceeds to the Company of approximately $293.2 million after a debt discount of $2.2 million and initial debt issuance costs of $4.6 million. The Senior Notes were issued pursuant to an indenture (the “Indenture”), dated as of October 20, 2010 by and among the Company, its subsidiary guarantors and Wilmington Trust FSB, as trustee (the “Trustee”).

The Senior Notes mature on November 1, 2018, and bear interest at a rate of 7.625% per annum, payable semi-annually in cash in arrears on May 1 and November 1 of each year, beginning on May 1, 2011. The Senior Notes are senior unsecured obligations of the Company and are guaranteed by substantially all of the Company's existing and future subsidiaries that guarantee obligations under the Company's Amended Credit Agreement.

In April 2011, the Company filed an amended registration statement with the Securities and Exchange Commission with respect to an offer to exchange the Senior Notes for a new issue of debt securities registered under the Securities Act (the “Exchange Offer”), with terms substantially identical to those of the Senior Notes, (except for provisions relating to the transfer restrictions and payment of additional interest), and to keep the Exchange Offer open for at least 30 business days (the “Registration Statement”). The Registration Statement was consummated in June 2011.

Amended Credit Agreement

On August 3, 2011, the Company entered into a Fifth Amended and Restated Credit Agreement (the “Credit Agreement”), as Borrower, with Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer (the “Lender”). The Credit Agreement amends and restates in its entirety an existing Fourth Amended and Restated Credit Agreement dated May 4, 2011 among the Company, as Borrower, and the Lender, as Administrative Agent (the “Existing Agreement”), which provided for a $260 million revolving credit facility and an additional $99.6 million under a supplemental facility.

The Credit Agreement replaces the Existing Agreement and allows the Company to borrow up to $300 million on a revolving credit basis (the “Revolving Facility”), with a $50 million sublimit for letters of credit, and an additional $200 million term loan (the “Term Loan”). Subject to certain conditions, the Company has the option to increase the base facility by up to an additional $50 million. Substantially all of the Company's subsidiaries unconditionally guarantee the obligations of the Company under the Credit Agreement. The obligations under the Credit Agreement are secured by a lien on all personal property of the Company and its subsidiaries party thereto. Amounts outstanding under the Credit Agreement bear interest at a rate equal to, at the Company's option, (a) the adjusted British Bankers Association LIBOR rate, as defined, plus 200 to 300 basis points (floor of 200 basis points) based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA or (b) the higher of the Federal Funds Rate plus 50 basis points, or the prime rate announced by Bank of America, N.A., plus up to 200 basis points based on the ratio of consolidated funded indebtedness of the Company and its subsidiaries to consolidated EBITDA. In addition, the Company has agreed to pay quarterly facility fees ranging from 0.375% to 0.50% per annum of the unused portion of the credit facility. Any outstanding loans under the Revolving Facility mature on August 3, 2016, while the Term Loan includes annual installments of principal and interest payable over a five-year period.

Similar to the Existing Agreement, the Credit Agreement requires the Company to comply with certain financial and other covenants including minimum net worth, minimum fixed charge coverage and maximum leverage ratios. The Company is currently in compliance with the covenants of the Credit Agreement.

The Credit Agreement also includes certain customary provisions for this type of facility, including operational covenants restricting liens, investments, indebtedness, fundamental changes in corporate organization, and dispositions of property, and events of default, certain of which include corresponding grace periods and notice requirements.

The Credit Agreement provides for customary events of default with corresponding grace periods, including (i) failure to pay any principal or interest when due, (ii) failure to comply with covenants, (iii) any material representation or warranty made by the Company proving to be incorrect in any material respect, (iv) defaults relating to or acceleration of other material indebtedness, (v) certain insolvency or receivership events affecting the Company, (vi) a change in control of the Company, or (vii) the Company becoming subject to certain material judgments.

In the event of a default, the Administrative Agent, at the request of the requisite number of lenders, must terminate the lenders' commitments to make loans under the Credit Agreement and declare all obligations under the Credit Agreement immediately due and payable. For certain events of default related to insolvency and receivership, the commitments of the lenders will be automatically terminated and all outstanding obligations of the Company under the Credit Agreement will become immediately due and payable.

The Company had $200 million of outstanding borrowings under its Revolving Facility as of June 30, 2011 and no outstanding borrowings as of December 31, 2010. The Company utilized the Revolving Facility for letters of credit in the amount of $3.0 million and $0.2 million as of June 30, 2011 and December 31, 2010, respectively. Accordingly, at June 30, 2011, the Company had $156.6 million available to borrow under the Existing Agreement, including the Supplemental Facility.

Debt Agreements from Recent Acquisitions

In connection with the acquisition of Frontier-Kemper (see Note 3), the Company assumed approximately $52 million of debt of which approximately $35 million was paid off upon the closing of the transaction. Substantially all of the debt remaining exists in the form of a promissory note payable from Frontier-Kemper to the former sole shareholder of Frontier-Kemper in the amount of $17.3 million (the “Frontier-Kemper Seller Note”). Interest under the Frontier-Kemper Seller Note accrues at the rate of 2% per annum with all accrued but unpaid interest payable on September 30, 2011. Additionally, the Frontier-Kemper Seller Note contains an indemnification provision allowing the Company to offset balances against the principal due under certain circumstances. The Frontier-Kemper Seller Note matures on December 31, 2011. The Company may prepay all or any portion of the Frontier-Kemper Seller Note at any time without premium or penalty.

In connection with the July 1, 2011 acquisitions of Lunda Construction Company (“Lunda”) and GreenStar Services Corporation (“GreenStar”), the Company issued additional promissory notes. The material terms of the promissory notes are described in further detail in Note 16.

Collateralized Loans

In March 2011, the Company paid off and subsequently refinanced several of its equipment financing agreements at lower interest rates and also entered into several new equipment financing agreements. The refinancing resulted in payments totaling $27.4 million which paid off the previous agreements in place. The Company obtained loans totaling $59.7 million, which are collateralized by construction equipment owned by the Company. The terms of the loans include equal monthly installments inclusive of principal and interest at an interest rate of 3.98% payable over a five-year period, with balloon payments totaling $9.0 million in 2016.
