Item 1.01. Entry into a Material Definitive Agreement.

On February 3, 2014, Lamar Media Corp. (“Lamar Media”), a wholly owned subsidiary of Lamar Advertising Company (“Lamar Advertising” or the “Company”), entered into a Second Restatement Agreement (the “Second Restatement Agreement”) with Lamar Advertising, certain of Lamar Media’s subsidiaries as Guarantors, JPMorgan Chase Bank, N.A. as Administrative Agent and the Lenders named therein under which the parties agreed to amend and restate Lamar Media’s existing senior credit facility on the terms set forth in the Second Amended and Restated Credit Agreement attached as Exhibit A to the Second Restatement Agreement (such Second and Amended and Restated Credit Agreement together with the Second Restatement Agreement being herein referred to as the “Amended Senior Credit Agreement”). The Amended Senior Credit Agreement increases (i) the revolving credit facility from $250 million to $400 million and (ii) the incremental facility from $300 million to $500 million. In addition, the Amended Senior Credit Agreement contains provisions that would allow Lamar Media to conduct its affairs in a manner that would allow Lamar Advertising to qualify and remain qualified as a REIT, including by allowing Lamar Media to make distributions to Lamar Advertising required for the Company to qualify and remain qualified for taxation as a REIT, subject to certain restrictions. It also eliminates a requirement that Lamar Media make mandatory prepayments on loans in certain circumstances based on excess cash flow. The maturity date of the revolving credit facility was extended to February 2, 2019. As of the date hereof, there are no outstanding term loans under the Amended Senior Credit Agreement and Lamar Media’s lenders have no obligation to make additional loans under the incremental facility, but may enter into such commitments in their sole discretion.

In addition, the covenants that Lamar Media and its restricted subsidiaries must adhere to under the Amended Senior Credit Agreement were amended to require that the following financial ratio that must be maintained:

The amended definition of “EBITDA” in the Amended Senior Credit Agreement is as follows: “EBITDA” means, for any period, operating income for the Company and its restricted subsidiaries (determined on a consolidated basis without duplication in accordance with GAAP) for such period (calculated before (i) taxes, (ii) interest expense, (iii) depreciation, (iv) amortization, (v) any other non-cash income or charges accrued for such period, (vi) charges and expenses in connection with the credit facility transactions, (vii) costs and expenses of Lamar Advertising associated with the REIT conversion, provided that the aggregate amount of costs and expenses that may be added back pursuant to this clause (vii) shall not exceed $10,000,000 in the aggregate and (viii) the amount of cost savings, operating expense reductions and other operating improvements or synergies projected by the Lamar Media in good faith to be realized as a result of any acquisition, investment, merger, amalgamation or disposition within 12 months of any such acquisition, investment, merger, amalgamation or disposition, net of the amount of actual benefits realized during such period from such action; provided, (a) the aggregate amount for all such cost savings, operating expense reductions and other operating improvements or synergies shall not exceed an amount equal to 15% of EBITDA for the applicable four quarter period and (b) any such adjustment to EBITDA may only take into account cost savings, operating expense reductions and other operating improvements or synergies that are (I) directly attributable to such acquisition, investment, merger, amalgamation or disposition, (II) expected to have a continuing impact on the Lamar Media and its restricted subsidiaries and (III) factually supportable, in each case all as certified by the chief financial officer of the Lamar Media on behalf of the Lamar Media, and (ix) any loss or gain relating to amounts paid or earned in cash prior to the stated settlement date of any swap agreement that has been reflected in operating income for such period) and (except to the extent received or paid in cash by Company and its restricted subsidiaries income or loss attributable to equity in affiliates for such period), excluding any extraordinary and unusual gains or losses during such period, and excluding the proceeds of any casualty events whereby insurance or other proceeds are received and certain dispositions. For purposes of calculating EBITDA, the effect on such calculation of any adjustments required under Statement of Financial Accounting Standards No. 141R is excluded.

The foregoing description of the Amended Senior Credit Agreement, is qualified in its entirety by reference to the complete text of the Amended Senior Credit Agreement, which is filed as Exhibit 10.1 to this report and incorporated herein by reference.
