Credit Agreements

Revolving Credit Facility

On December 28, 2012, the Company entered into a revolving credit facility (the “Credit Agreement”), by and among the Company, The PrivateBank and Trust Company, as administrative agent (the “Administrative Agent”) and co-lead arranger, The Bank of the West, as co-lead arranger and IBERIABANK Corporation (the “Lenders”). The Credit Agreement is a $75 million revolving credit facility whereby the lenders agree to make loans on a revolving basis from time to time and to issue letters of credit for up to the $75 million committed amount. The Credit Agreement also provides for an incremental facility of up to $50 million. The termination date of the Credit Agreement is December 28, 2017.

The principal amount of any loans under the Credit Agreement will bear interest at either: (i) LIBOR plus an applicable margin as specified in the Credit Agreement (based on the Company’s senior debt to EBITDA ratio), or (ii) the Base Rate (which is the greater of (a) the Federal Funds Rate plus 0.5% or (b) the prime rate as announced by the Administrative Agent). Quarterly non-use fees, letter of credit fees and administrative agent fees are payable by the Company at rates specified in the Credit Agreement.

The principal amount of any loan drawn under the Credit Agreement may be prepaid in whole or in part, with a minimum prepayment of $5 million, at any time, potentially subject to make-whole provisions.

The Credit Agreement includes customary restrictive covenants for facilities of this type, as discussed below.

Other than commercial letters of credit amounting to $4,808, there were no borrowings under this line of credit during the twelve months ended December 31, 2012, leaving available borrowing capacity at $70,192.

As part of the execution of the Credit Agreement described above, the previous Loan and Security Agreement dated October 29, 2009, as amended, between the Company and The Private Bank and Trust Company (the “PrivateBank Agreement”), was terminated. The Company was in compliance with the bank covenants at the time of the termination and there were no penalties or fees incurred as a result of the termination. There were no borrowings outstanding at the time of the termination and all letter of credit amounts issued and outstanding under the terminated agreement were transferred to the Lenders under the Credit Agreement discussed above.

In 2011, the Company entered into an agreement with Bank of the West whereby the Company agrees to maintain a cash balance at the bank equal to the full amount of certain commercial letters of credit. The agreement was terminated and all the remaining liabilities were transferred to the Credit Agreement discussed above.

Senior Secured Notes and Shelf Agreement

On December 28, 2012, the Company also entered into a $50 million Senior Secured Notes purchase (“Senior Notes”) and a $25 million private shelf agreement (the “Notes Agreement”) by and among the Company and The Prudential Investment Management, Inc. and certain Prudential affiliates (the “Noteholders”).

A total of $50 million in Senior Notes was funded on December 28, 2012. The Senior Notes are due December 28, 2022 and bear interest at an annual rate of 3.65%, paid quarterly in arrears. Annual principal payments of $7.1 million are required beginning December 28, 2016 through December 28, 2021 with a final payment due on December 28, 2022. The principal amount may be prepaid in whole or in part, with a minimum prepayment of $5 million, at any time, subject to make-whole provisions.

The Notes Agreement provides for the issuance of additional notes of up to $25 million, during the first three years of the Notes Agreement with maturity dates no more than 10 years from the date issued, at the market interest rate for notes with equivalent terms and conditions.

All loans made under both the Credit Agreement and the Notes Agreement are secured by our assets, including, among others, our cash, inventory, goods, equipment (excluding equipment subject to permitted liens) and accounts receivable. All of our domestic subsidiaries have issued joint and several guaranties in favor of the Lenders and Noteholders for all amounts under the Credit Agreement and Notes Agreement.

Both the Credit Agreement and the Notes Agreement contain various restrictive and financial covenants including among others, minimum tangible net worth, senior debt/EBITDA ratio, debt service coverage requirements and a minimum balance for unencumbered net book value for fixed assets. In addition, the agreements include restrictions on investments, change of control provisions and provisions in the event the Company disposes more than 20% of its total assets.

The Company was in compliance with the bank covenants as of December 31, 2012.

Canadian Credit Facility

The Company has a credit facility with a Canadian bank for purposes of issuing commercial letters of credit in Canada, for an amount of up to $10,000 in Canadian dollars. The credit facility has an annual renewal and provides for the issuance of commercial letters of credit for a term of up to five years. The facility provides for an annual fee of 1% for any issued and outstanding commercial letters of credit. Letters of credit can be denominated in either Canadian or U.S. dollars. At December 31, 2012 and 2011, commercial letters of credit outstanding under this credit facility totaled $1,364 and $4,036 in Canadian dollars, respectively. At December 31, 2012, the available borrowing capacity under this credit facility was $8,636 in Canadian dollars.

Subordinated Promissory Note — Rockford. In connection with the 2010 acquisition of Rockford, the Company executed an unsecured promissory note (the “Rockford Note”).

As a result of a dispute related to a certain liability at the time of the closing of the transaction, the Company ceased making principal and interest payments in May 2012, when the outstanding balance reached $5,000. The balance was reclassified on the Company’s balance sheet from notes payable to accrued liabilities in September 2012.

In December 2012, the parties came to a resolution whereby the Company would pay $1,500 to cancel the subordinated note. Final payment is expected in the first quarter of 2013.

Subordinated Promissory Note — JCG. In connection with the acquisition of JCG, the Company executed an unsecured promissory note (the “JCG Note”) on December 18, 2009 in favor of the sellers of JCG with an initial principal amount of $53,500. The JCG Note was due and payable on December 15, 2014 and bore interest at differing rates until maturity. The JCG note was paid in full on March 12, 2012.
