INTRODUCTORY NOTE

On July 25, 2012, Universal Truckload Services, Inc., a Michigan corporation (“Universal”), and LINC Logistics Company, a Michigan corporation (“LINC”), announced that their respective boards of directors adopted and the parties entered into an Agreement and Plan of Merger (the “Merger Agreement”) by and among LINC, Universal, Upton Merger Sub I, Inc., a Michigan corporation, Upton Merger Sub II, LLC, a Michigan limited liability company, Matthew T. Moroun, Matthew T. Moroun as Trustee of the Manuel J. Moroun 2012 Annuity Trust dated April 30, 2012, Manuel J. Moroun, in his capacity as Trustee of the Manuel J. Moroun Revocable Trust U/A dated March 24, 1977, as amended and restated on December 22, 2004, Matthew T. Moroun, in his capacity as agent and attorney-in-fact for the Company Shareholders (as defined in the Merger Agreement), and Manuel J. Moroun, solely with respect to the Applicable Sections (as defined in the Merger Agreement).

On August 30, 2012, Universal entered into a Revolving Credit and Term Loan Agreement, dated as of August 28, 2012 (the “Credit Agreement”), with and among the lenders parties thereto and Comerica Bank, as administrative agent, arranger and documentation agent, providing for aggregate borrowing facilities of up to $220,000,000. Pursuant to the Credit Agreement, the lenders thereunder shall not be obligated to make any advances or loans under the Credit Agreement until all conditions precedent have been satisfied, including that all conditions to consummate the mergers contemplated by the Merger Agreement have been satisfied. Entering into the Credit Agreement is a closing condition pursuant to the Merger Agreement.

The Credit Agreement consists of a $110,000,000 revolving credit facility (which amount may be increased by up to $20,000,000 upon request of Universal and approval of the lenders), a $60,000,000 equipment credit facility, and a $50,000,000 term loan. Borrowings under the revolving credit facility may be made until, and mature on, August 28, 2017. Borrowings under the equipment credit facility may be made until August 28, 2015 and such borrowings made in any year shall be repaid in 28 quarterly installments beginning on April 1 of the year after the applicable borrowing was made. Borrowings under the term loan facility shall be made on the Effective Date and shall mature on August 28, 2017.

Borrowings under the Credit Agreement bear interest at LIBOR or a base rate, plus an applicable margin for each. The applicable margin fluctuates based on Universal’s total debt to EBITDA ratio, as defined in the Credit Agreement. Additionally, the Credit Agreement provides for up to $5,000,000 in letters of credit, which letters of credit reduce availability under the revolving credit facility.

The Credit Agreement requires Universal to repay the borrowings made under the term loan facility and the equipment credit facility as follows:

Universal may voluntarily repay outstanding loans under each of the facilities at any time, subject to certain customary “breakage” costs with respect to LIBOR-based borrowings. In addition, Universal may elect to permanently terminate or reduce all or a portion of the revolving credit facility.

All obligations under the Credit Agreement are unconditionally guaranteed by Universal’s material U.S. subsidiaries and the obligations of Universal and such subsidiaries under the Credit Agreement and such guarantees are secured by, subject to certain exceptions, substantially all of their assets.

The Credit Agreement includes financial covenants requiring Universal to maintain maximum leverage ratios and a minimum fixed charge coverage ratio, as well as customary affirmative and negative covenants and events of default.

Initial advances made under the Credit Agreement are subject to, among other things, the satisfaction of all conditions to closing in connection with the merger under the Merger Agreement.

Universal expects to borrow funds under the Credit Agreement on the Effective Date to pay off LINC’s existing indebtedness to lenders, to pay off obligations of LINC to its current and former shareholders and affiliates and to pay fees and transaction costs related to the merger and the Credit Agreement. Universal expects to use the proceeds of any borrowings under the Credit Agreement after the merger for general corporate purposes.

The foregoing summary of the Credit Agreement does not purport to be complete and is subject to, and qualified in its entirety by, the full text of the Credit Agreement, which is filed as Exhibit 10.1 and is incorporated by reference into this report.

The information set forth under Item 1.01 of this current report on Form 8-K is hereby incorporated by reference into this Item 2.03.
