Amendment of a Material Definitive Agreement with Credit Facility Lenders

On October 7, 2013, Vitran Corporation Inc. (the “Company” or “Vitran”) and certain of its subsidiaries entered into the Fifth Amendment to Credit Agreement (the “Amending Agreement”) amending its Credit Agreement dated November 30, 2011 (the “Original Credit Agreement”) among the Company, certain of its subsidiaries, JPMorgan Chase Bank, N.A., as agent (the “Agent”), and the lenders that are party thereto (the “Lending Group”). The Original Credit Agreement continues in full force and effect, other than as amended by the Amending Agreement, the First Amendment to Credit Agreement dated as of December 29, 2011, the Second Amendment to Credit Agreement dated as of October 10, 2012, the Third Amendment to Credit Agreement dated as of December 28, 2012, and the Fourth Amendment to Credit Agreement dated as of February 12, 2013 (the Original Credit Agreement as amended, the “Credit Agreement”).

The following is a summary of the material terms of the amendments to the Credit Agreement effected by the Amending Agreement:

The Amending Agreement provides consent to the Company from the Lending Group for the sale of the Company’s subsidiaries that formed its U.S. LTL business.

The foregoing description of the Amending Agreement is qualified in its entirety by reference to the full text of the Amending Agreement, a copy of which is attached hereto as Exhibit 10.1 and is hereby incorporated by reference into this Current Report on Form 8-K.

Completion of Divestiture of U.S. LTL Business to Data Processing, LLC

As previously disclosed on the Company’s Form 8-K filed on September 26, 2013, Vitran entered into a Stock Sale and Purchase Agreement with Data Processing, LLC (the “Buyer”) on September 23, 2013. Under the sale transaction, the Buyer acquired 100% of the common stock of the wholly-owned subsidiary which operates Vitran’s U.S. LTL business.

The transaction closed on October 7, 2013 (the “Closing Date”). In order to complete the transaction, the Company capitalized the U.S. LTL business with the net amount of $3.0 million, after deducting the $2.0 million purchase price received by the Company from the Buyer. In addition, the Buyer funded a cash deficit of approximately $1.4 million in the U.S. LTL business between September 23, 2013 and the Closing Date.

As part of the sale transaction, the obligations under the letters of credit currently outstanding for the U.S. LTL business remain guaranteed by the Company’s Canadian LTL business. However, the Buyer has agreed to reduce such letters of credit to zero within 90 days of the Closing Date.

The unaudited pro forma consolidated balance sheet dated June 30, 2013, and unaudited pro forma consolidated statements of income (loss) of the Company for the six months ended June 30, 2013 and for the fiscal years ended December 31, 2012, 2011 and 2010 are filed as Exhibit 99.1 to this Current Report on Form 8-K.
