On December 28, 2012, Primoris Services Corporation entered into a revolving credit facility, by and among the company, The PrivateBank and Trust Company, as administrative agent and co-lead arranger, The Bank of the West, as co-lead arranger and IBERIABANK Corporation. 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: LIBOR plus an applicable margin as specified in the credit agreement (based on the company's senior debt to EBITDA ratio), or the Base Rate (which is the greater of the Federal Funds Rate plus 0.5% or 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.
