On June 14, 2013, Quality Distribution, Inc. (the “Company”) and its wholly owned subsidiary, Quality Distribution, LLC (“QD LLC”), added a $17.5 million senior secured term loan facility (the “Term Loan Facility”) to QD LLC’s existing senior secured asset-based revolving credit facility (the “ABL Facility”) pursuant to the Credit Agreement dated as of August 19, 2011, with Bank of America, N.A., as administrative agent and collateral agent, and the lenders party thereto from time to time (as amended, including pursuant to the Second Amendment described below, the “Amended Credit Agreement”). QD LLC expects to use the proceeds of the Term Loan Facility, together with borrowings under the ABL Facility and/or cash on hand, to effect the redemption described below under “Other Events.”

The increase was effectuated through a Second Amendment to Credit Agreement (the “Second Amendment”) dated as of June 14, 2013 (the “Amendment Effective Date”), among the Company, QD LLC, the other loan parties party thereto, Bank of America, N.A., as administrative agent and collateral agent, and the lenders party thereto. The Amended Credit Agreement permits QD LLC to draw a term loan in an aggregate principal amount not to exceed $17.5 million.

One borrowing under the Term Loan Facility may be made at any time during the 60-day period commencing on the Amendment Effective Date. Borrowings under the Term Loan Facility bear interest at a rate per annum equal to an applicable margin plus, at the Company’s option, either a base rate or LIBOR. The initial applicable margin is 2.50% for base rate borrowings and 3.50% for LIBOR borrowings, with a potential step-down after 18 months based on a senior secured leverage ratio to 2.25% for base rate borrowings and 3.25% for LIBOR borrowings. QD LLC may voluntarily repay outstanding loans under the Term Loan Facility at any time without premium or penalty, other than customary “breakage” costs with respect to LIBOR loans. Obligations under the Term Loan Facility mature on the earlier of third anniversary of the Amendment Effective Date and the date on which the ABL Facility terminates.

All obligations under the Term Loan Facility are guaranteed by the Company and the Company’s wholly-owned domestic restricted subsidiaries (other than immaterial subsidiaries) pursuant to a Guarantee and Collateral Agreement, dated as of August 19, 2011, among the Company, QD LLC, each of the Company’s subsidiaries party thereto, and Bank of America, N.A., as administrative agent and collateral agent (the “Guarantee and Collateral Agreement”). Further, pursuant to the Guarantee and Collateral Agreement obligations under the Term Loan Facility, and the guarantees of those obligations (as well as cash management obligations and any interest hedging or other swap agreements), are secured by a first priority lien on substantially all of the assets of QD LLC and the guarantors.

The Term Loan Facility is otherwise subject to terms and conditions similar to those applicable to the ABL Facility. The maturity, interest rate and other material terms and conditions of the ABL Facility remain the same.

The foregoing description of the Second Amendment does not purport to be complete and is qualified in its entirety by reference to the full text of the Second Amendment, a copy of which is filed herewith as Exhibit 10.1 and is incorporated in this Item 1.01 by reference.

On June 17, 2013, the Company announced that its wholly owned subsidiaries, Quality Distribution, LLC and QD Capital Corporation, plan to redeem $22,500,000 outstanding principal amount of their 9.875% Second-Priority Senior Secured Notes due 2018 on July 15, 2013 (the “Redemption Date”). The redemption price for the 2018 Notes will be equal to 100% of the aggregate redemption amount of $22.5 million (plus accrued but unpaid interest up to the Redemption Date) plus a 3.0% premium. This redemption is expected to be funded with net proceeds from the Term Loan Facility, plus borrowings under the existing ABL Facility and/or cash on hand.
