The information required by item 1.01 is included in Item 2.03 and is incorporated by reference herein.

On December 19, 2013, CatchMark Timber Trust, Inc. (the “Company”), through Timberlands II, LLC and CatchMark Timber Operating Partnership, L.P. (together, the “Borrowers”), entered into a third amended and restated credit agreement (the “Credit Agreement”) with CoBank, ACB (“CoBank”), as administrative agent, joint lead arranger, sole bookrunner, swingline lender and issuing lender, Agfirst Farm Credit Bank, (“Agfirst”), joint lead arranger and syndication agent, and Cooperatieve Centrale Raiffelsen-Boerenleenbank, B.A. (“RaboBank”), as documentation agent, and certain financial institutions, as lenders. The Credit Agreement amends and restates in its entirety the pre-existing senior credit agreement, dated as of September 28, 2012, by and among the Borrowers and CoBank, as administrative agent, lead arranger, and bookrunner, RaboBank, as documentation agent, and Agfirst, as syndication agent, and certain financial institutions, as lenders.

The Credit Agreement provides for borrowing, in each case subject to limitations on availability as set forth therein, under credit facilities consisting of:

The Credit Agreement provides that the New Credit Facilities may be increased, upon the agreement of lenders willing to increase their loans, by up to $75.0 million, consisting of up to a $10.0 million increase in the Revolving Credit Facility and the remainder available for incremental term loans.

Borrowings under the Revolving Credit Facility may be used for working capital, to support letters of credit and other general corporate purposes, but may not be used for timber acquisitions. The Revolving Credit Facility will bear interest at an adjustable rate equal to a base rate plus between 0.50% and 1.75% or a LIBOR rate plus between 1.50% and 2.75%, in each case depending on our loan to value (“LTV”) ratio, and will terminate and all amounts under the facility will be due and payable on December 19, 2018.

The Multi-Draw Credit Facility may be drawn upon up to five times during the period beginning on December 19, 2013 through December 19, 2016 and may be used to finance domestic timber acquisitions and associated expenses. Amounts repaid under the Multi-Draw Credit Facility may be reborrowed prior to the third anniversary of the closing date. The Multi-Draw Facility will bear interest at an adjustable rate equal to a base rate plus between 0.75% and 2.00% or a LIBOR rate plus between 1.75% and 3.00%, in each case depending on our LTV ratio, and will terminate and all amounts under the facility will be due and payable on December 19, 2020. The Multi-Draw Credit Facility is interest only until the maturity date; however, if the Company’s LTV ratio is equal to or in excess of 35%, then principal payments will be required to be made beginning on December 31, 2016 at a per annum rate of 7.5% of the principal amount outstanding under the Multi-Draw Credit Facility.

The Term Loan Facility will bear interest at an adjustable rate equal to a base rate plus between 0.50% and 1.75% or a LIBOR rate plus between 1.50% and 2.75%, in each case depending on the Company’s LTV ratio, and will terminate and all amounts under the facility will be due and payable on December 19, 2018.

The representations and covenants contained in the Credit Agreement are customary for financing transactions of this nature including, among others, a requirement that the LTV ratio not exceed 45% at any time and a minimum liquidity balance until the date that the Company has achieved a fixed charge coverage ratio of not less than 1.05:1 (after such date the Company must maintain a fixed coverage charge ratio of not less than 1.05:1), in each case as set forth in the Credit Agreement. In addition, certain other covenants could restrict the Company’s ability to incur additional debt, pay dividends or acquire or dispose of assets.

The Credit Agreement also provides for events of default that are customary for financing transactions of this nature, including cross-defaults to other material indebtedness. Upon the occurrence of an event of default, the Company could be required to immediately repay all amounts outstanding under the applicable facility.

The Borrowers’ obligations under the Credit Agreement are collateralized by a first priority lien on the timberlands owned by the Company’s subsidiaries and substantially all of the Borrowers’ and each of their subsidiaries’ other assets in which a security interest may lawfully be granted, including, without limitation, accounts, equipment, inventory, intellectual property, bank accounts and investment property. In addition, the Borrowers’ obligations under the Credit Agreement are guaranteed by the all of the Borrowers’ subsidiaries. The Company has also agreed to guarantee certain losses caused by certain willful acts of the Borrowers.

The Company and certain of its affiliates may have commercial banking, investment banking and retail lending and other relationships with certain of the lenders under the New Credit Facilities and/or their respective affiliates. These lenders, or their respective affiliates, have received, and may in the future receive, customary fees and expenses for those services.
