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.

The terms of the Indenture, among other things, limit the ability of the Company and its restricted subsidiaries to (i) incur additional indebtedness or issue certain preferred stock; (ii) pay dividends on, or make distributions in respect of, the Company’s capital stock or repurchase the Company’s capital stock; (iii) make certain investments or other restricted payments; (iv) sell certain assets; (v) create liens or use assets as security in other transactions; (vi) merge, consolidate or transfer or dispose of substantially all of the Company’s assets; and (vii) engage in certain transactions with affiliates.

The Senior Notes are redeemable, in whole or in part, at any time on or after November 1, 2014, at the redemption prices specified in the Indenture, together with accrued and unpaid interest, if any, to the redemption date. At any time prior to November 1, 2013, the Company could have redeemed up to 35% of the aggregate principal amount of the Senior Notes with the net cash proceeds from certain equity offerings at a redemption price equal to 107.625% of the principal amount thereof, together with accrued and unpaid interest, if any, to the redemption date. In addition, at any time prior to November 1, 2014, the Company may redeem the Senior Notes, in whole or in part, at a redemption price equal to 100% of the principal amount of the Senior Notes so redeemed, plus a “make whole” premium, together with accrued and unpaid interest, if any, to the redemption date.

Upon the occurrence of a change of control triggering event specified in the Indenture, the Company must offer to purchase the Senior Notes at a redemption price equal to 101% of the principal amount thereof, plus accrued and unpaid interest, if any, to the date of purchase.

The Indenture provides for customary events of default (subject in certain cases to customary grace and cure periods), which include nonpayment, breach of covenants in the Indenture, payment defaults or acceleration of other indebtedness, a failure to pay certain judgments and certain events of bankruptcy and insolvency. If an event of default occurs and is continuing, the Trustee or holders of at least 25% in principal amount of the outstanding Senior Notes may declare the principal, accrued and unpaid interest, if any, on all the Senior Notes to be due and payable.

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 Exchange Offer 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”) with Bank of America, N.A., which has been amended by a Joinder Agreement dated October 21, 2011 executed by Becho, Inc. The Credit Agreement 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”).

On August 2, 2012, the Company entered into a First Amendment (the “First Amendment”) to its Fifth Amended and Restated Credit Agreement (the “Amended Credit Agreement”) with Bank of America, N.A., as Administrative Agent, Swing Line Lender and L/C Issuer (the “Lender”). The First Amendment modifies the financial covenants under the Amended Credit Agreement beginning with the period ended September 30, 2012 to allow for more favorable minimum net worth, minimum fixed charge and maximum leverage ratios for the Company and also to add new financial covenants including minimum liquidity and consolidated senior leverage ratio covenants. The First Amendment also increases the sublimit for letters of credit from $50 million to $150 million.

Under the First Amendment, the minimum net worth covenant is modified such that the consolidated net worth of the Company cannot be less than the sum of: (i) 85% of the consolidated net worth as of March 31, 2012 less the actual goodwill and intangible assets impairment charge taken on or before September 30, 2012, not to exceed $450.0 million; (ii) an amount equal to 50% of net income for each fiscal quarter ending after June 30, 2012 (with no deduction for net losses); and (iii) an amount equal to 100% of the aggregate amount of all equity issuances after June 30, 2012 that increase stockholder’s equity. The minimum fixed charge ratio covenant is modified such that the minimum fixed charge ratio shall not be less than 1.00 to 1.00 for the quarterly periods ending September 30, 2012 and December 31, 2012, 1.10 to 1.00 for the quarterly periods ending March 31, 2013 and June 30, 2013, and 1.25 to 1.00 for the quarterly periods ending September 30, 2013 and thereafter. The consolidated leverage ratio covenant is modified such that the consolidated leverage ratio shall not be greater than 4.25 to 1.00 for the quarterly periods ending September 30, 2012 through March 31, 2013, 3.75 to 1.00 for the quarterly periods ending June 30, 2013 through December 31, 2013, 3.25 to 1.00 for the quarterly periods ending March 31, 2014 through September 30, 2014 and 2.75 to 1.00 for the quarterly periods ending December 31, 2014 and thereafter. The First Amendment allows for an add-back to EBITDA of up to $450.0 million for any goodwill and intangible asset impairment charges that impact the ratios for all fiscal quarters through March 31, 2013.

The Company was in compliance with the modified financial covenants of the Amended Credit Agreement for the period ended December 31, 2013.

The First Amendment also modifies the applicable interest rates for amounts outstanding such that they 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 400 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 300 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 0.700% per annum of the unused portion of the credit facility.

The Amended Credit Agreement increases the sublimit for letters of credit from $50 million to $150 million. Substantially all of the Company’s subsidiaries unconditionally guarantee the obligations of the Company under the Amended Credit Agreement. The obligations under the Amended Credit Agreement are secured by a lien on all personal property of the Company and its subsidiaries party thereto. Any outstanding loans under the Revolving Facility mature on August 3, 2016, while the Term Loan includes quarterly installments of principal and interest payable over a five-year period. The Term Loan balance has been paid down to $115.0 million at December 31, 2013.

The Amended 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 Amended 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 Amended Credit Agreement and declare all obligations under the Amended 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 Amended Credit Agreement will become immediately due and payable.

The Company had $135.0 million of outstanding borrowings under the Revolving Facility as of December 31, 2013 and $120.0 million of outstanding borrowings as of December 31, 2012. The Company utilized the Revolving Facility for letters of credit in the amount of $0.2 million as of both December 31, 2013 and 2012. Accordingly, at December 31, 2013, the Company had $164.9 million available to borrow under the Amended Credit Agreement.

On August 26, 2011, the Company entered into a swap agreement (“Swap Agreement”) with Bank of America, N.A. to establish a long-term interest rate for the Term Loan discussed above. The Swap Agreement pertains to the Term Loan principal balance outstanding at January 31, 2012 and will remain effective through the maturity date of the Term Loan. Amounts outstanding under the Swap Agreement will bear interest at a rate equal to the Applicable Rate, as defined in the Amended Credit Agreement (based upon the Company’s consolidated leverage ratio) plus 97.5 basis points. The Swap Agreement includes quarterly installments of principal and monthly installments of interest payable through the maturity date of the Term Loan.

Debt Agreements from Recent Acquisitions

In connection with the acquisition of Frontier-Kemper and GreenStar, we assumed certain debt, all of which was paid off in 2011.

In connection with the acquisition of Lunda, the Company issued to the former Lunda shareholders promissory notes in an aggregate amount of approximately $21.7 million (the “Lunda Seller Notes”). Interest under the Lunda Seller Notes accrues at the rate of 5% per annum with all accrued but unpaid interest payable annually. The Lunda Seller Notes mature on July 1, 2016. The Company may prepay all or any portion of the Lunda Seller Notes at any time without premium or penalty. To the extent that the Company prepays all or any portion of its outstanding Senior Notes, it is also required to repay a pro rata portion (based upon the amount being prepaid under the Senior Notes and the total amount outstanding under the Senior Notes) of the Lunda Seller Notes. The Lunda Seller Notes are guaranteed by Lunda, which, as a result of the acquisition, is a wholly owned subsidiary of the Company.

Collateralized Loans

During 2013 and 2011, the Company entered into several equipment financing arrangements for its existing and its recently acquired equipment fleets as discussed in more detail below. The Company attempted to take advantage of the opportunity to fix low interest rates for these fleets which has provided additional cash flows available for general corporate purposes.

During 2013, we obtained equipment financing totaling $25.8 million at fixed rates ranging from 2.28% to 3.09%, payable in equal monthly installments for sixty months. We obtained a mortgage loan of $9.6 million collateralized by land and improvements located in Houston, Texas, with equal monthly installments over a 30-year period at LIBOR plus 3.00% with a balloon payment of $6.7 million due in 2023.

In September 2011, the Company entered into two new equipment financing agreements. The Company obtained two loans for $12.5 million each, which are collateralized by construction equipment owned by the Company. The terms of each of the loans include equal monthly installments inclusive of principal and interest at an interest rate of 2.21% payable over a five-year period. In August 2011, the Company entered into a new equipment financing agreement. The Company obtained a loan totaling $25.0 million, which is collateralized by construction equipment owned by the Company. The terms of the loan include equal monthly installments inclusive of principal and interest at an interest rate of 2.53% payable over a five-year period. 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 $8.8 million in 2016.
