We and substantially all of our subsidiaries are parties to a Third Amended and Restated Credit Facility (the "Credit Facility") with Bank of America, N.A., as agent (the "Agent") and JPMorgan Chase Bank, N.A. (together with the Agent, the "Lenders").

The Credit Facility is a

$95.0

million revolving credit facility, with an uncommitted accordion feature that, so long as

event of default exists, allows us to request an increase in the revolving credit facility of up to

$50.0

million subject to Lender acceptance of the additional funding commitment. The Credit Facility includes, within our

$95.0

million revolving credit facility, a letter of credit sub facility in an aggregate amount of

$95.0

million and a swing line sub facility in an aggregate amount equal to the greater of

$10.0

million or

10%

of the Lenders' aggregate commitments under the Credit Facility from time-to-time. The Credit Facility matures in

September 2018.

Borrowings under the Credit Facility are classified as either "base rate loans" or "LIBOR loans." Base rate loans accrue interest at a base rate equal to the greater of the Agent's prime rate, the federal funds rate plus

0.5%,

or LIBOR plus

1.0%,

plus an applicable margin ranging from

0.5%

1.0%;

while LIBOR loans accrue interest at LIBOR, plus an applicable margin ranging from

1.5%

2.0%

The applicable rates are adjusted quarterly based on average pricing availability. The unused line fee is the product of

0.25%

times the average daily amount by which the Lenders' aggregate revolving commitments under the Credit Facility exceed the outstanding principal amount of revolver loans and the aggregate undrawn amount of all outstanding letters of credit issued under the Credit Facility. The obligations under the Credit Facility are guaranteed by us and secured by a pledge of substantially all of our assets, with the notable exclusion of any real estate or revenue equipment pledged under other financing agreements, including revenue equipment installment notes and capital leases.

Borrowings under the Credit Facility are subject to a borrowing base limited to the lesser of (A)

$95.0

million, minus the sum of the stated amount of all outstanding letters of credit; or (B) the sum of (i)

85%

of eligible accounts receivable, plus (ii) the lesser of (a)

85%

of the appraised net orderly liquidation value of eligible revenue equipment, (b)

95%

of the net book value of eligible revenue equipment, or (c)

35%

of the Lenders' aggregate revolving commitments under the Credit Facility, plus (iii) the lesser of (a)

$25.0

million or (b)

65%

of the appraised fair market value of eligible real estate.

We had

$4.1

million outstanding under the Credit Facility as of

June 30, 2017,

undrawn letters of credit outstanding of approximately

$30.9

million, and available borrowing capacity of

$55.9

million. The interest rate on outstanding borrowings as of

June 30, 2017,

was

4.8%

$4.1

million of base rate loans, and there were

outstanding LIBOR loans

Based on availability as of

June 30, 2017

and

December 31, 2016,

there was

fixed charge coverage requirement.

The Credit Facility includes usual and customary events of default for a facility of this nature and provides that, upon the occurrence and continuation of an event of default, payment of all amounts payable under the Credit Facility

may

be accelerated, and the Lenders' commitments

may

be terminated. If an event of default occurs under the Credit Facility and the Lenders cause or have the ability to cause all of the outstanding debt obligations under the Credit Facility to become due and payable, this could result in a default under other debt instruments that contain acceleration or cross-default provisions. The Credit Facility contains certain restrictions and covenants relating to, among other things, debt, dividends, liens, acquisitions and dispositions outside of the ordinary course of business, and affiliate transactions. Failure to comply with the covenants and restrictions set forth in the Credit Facility could result in an event of default.

Capital lease obligations are utilized to finance a portion of our revenue equipment and are entered into with certain finance companies who are

not

parties to our Credit Facility. The leases in effect at

June 30, 2017

terminate in

July 2017

through

March 2023

and contain guarantees of the residual value of the related equipment by us. As such, the residual guarantees are included in the related debt balance as a balloon payment at the end of the related term as well as included in the future minimum capital lease payments. These lease agreements require us to pay personal property taxes, maintenance, and operating expenses.

Pricing for the revenue equipment installment notes is quoted by the respective financial affiliates of our primary revenue equipment suppliers and other lenders at the funding of each group of equipment acquired and include fixed annual rates for new equipment under retail installment contracts. The notes included in the funding are due in monthly installments with final maturities at various dates ranging from

July 2017

June 2023.

The notes contain certain requirements regarding payment, insuring of collateral, and other matters, but do

not

have any financial or other material covenants or events of default except certain notes totaling

$138.0

million are cross-defaulted with the Credit Facility. Additionally, the abovementioned fuel hedge contracts totaling

$5.4

million at

June 30, 2017,

and are cross-defaulted with the Credit Facility. Concurrent with entering into certain of our revenue equipment installment notes, we entered into interest rate swaps to effectively fix the interest rates. See Note

for further information. Additional borrowings from the financial affiliates of our primary revenue equipment suppliers and other lenders are expected to be available to fund new tractors expected to be delivered for the remainder of

2017,

while any other property and equipment purchases, including trailers, are expected to be funded with a combination of available cash, notes, operating leases, capital leases, and/or from the Credit Facility.

August 2015,

we financed a portion of the purchase of our corporate headquarters, a maintenance facility, and certain surrounding property in Chattanooga, Tennessee by entering into a

$28.0

million variable rate note with a

third

party lender. Concurrently with entering into the note, we entered into an interest rate swap to effectively fix the related interest rate to

4.2%.

See Note

for further information about the interest rate swap.
