On April 12, 2013, EnerNOC, Inc. and ENOC Securities Corporation entered into a Second Amendment to its secured revolving credit facility with Silicon Valley Bank, dated March 14, 2012, as amended on June 29, 2012. The Second Amendment provides for an extension of the 2012 Credit Facility's revolving termination date from April 15, 2013 to April 30, 2013. On April 18, 2013, EnerNOC entered into a $70 million senior secured revolving credit facility pursuant to a Credit Agreement, among EnerNOC, the several lenders from time to time party thereto and Silicon Valley Bank, as administrative agent, swing line lender, issuing lender, lead arranger and book manager. Subject to continued covenant compliance, the 2013 Credit Agreement provides for a two-year revolving line of credit in the aggregate amount of $70 million, the full amount of which may be available for issuances of letters of credit and up to $5 million of which may be available for swing line loans. The revolving line of credit is subject to increase from time to time up to an aggregate amount of $100 million with additional commitments from the Lenders or new commitments from financial institutions acceptable to SVB. The interest on revolving loans under the 2013 Credit Agreement will accrue, at EnerNOC's election, at either the Eurodollar Rate with respect to the relevant interest period plus 2.00% or the ABR (defined as the highest of the prime rate as quoted in the Wall Street Journal, and the Federal Funds Effective Rate plus 0.50%) plus 1.00%. The 2013 Credit Agreement terminates and all amounts outstanding there under are due and payable in full on April 18, 2015.
