Entry into a Material Definitive Agreement with Legacy SCO, Inc.

Vitran Corporation Inc. (the “Company” or “Vitran”) has entered into an agreement dated February 12, 2013 with Legacy SCO Inc. (“Legacy”), an affiliate of Legacy Supply Chain, Inc., based in Portsmouth, New Hampshire, for the sale of the Company’s Supply Chain Operation (SCO) division to Legacy for U.S. $97.0 million in cash, subject to certain working capital adjustments. Vitran intends to use a portion of the net proceeds from this transaction to fully reduce its outstanding debt under its senior revolving credit facility and to support the development of its LTL business. Vitran’s Board of Directors is also evaluating various options for the use of the remaining net proceeds.

Legacy has obtained written commitments from certain financial institutions to provide sufficient debt financing for the transaction and has agreed to diligently work to complete the financing. The financing is subject to the completion of confirmatory due diligence. The sale of the SCO business is expected to close by March 1, 2013, upon completion of the Legacy financing, and is subject to customary conditions for this type of transaction.

The Company intends to file a current report disclosing the additional information required by Item 2.01 of Form 8-K upon completion of the transaction.
