Capitalized terms defined in the Credit Agreement and not otherwise defined or redefined herein are used herein with the meanings so defined.

NOW, THEREFORE, in consideration of the foregoing and for other good and valuable consideration, the receipt and sufficiency of which are hereby acknowledged, the parties hereto hereby agree as follows: 1. Amendment of Credit Agreement. The Credit Agreement is hereby amended as follows: 1.1. Table of Contents.

"Maximum Borrowing Base Real Property Amount" means $100,000,000 as such amount may be increased up to but not exceeding $115,000,000 as follows: (a) For every Asset Sale occurring after January 31, 1997 involving Revenue Equipment, the Net Cash Proceeds of which are used (i) to reduce the Term Advances or (ii) after the repayment in full of the Term Advances to permanently reduce the Revolving Commitments pursuant to Section 2.04, the Maximum Borrowing Base Real Property Amount shall be increased by one Dollar multiplied by a factor of 0.80 for each Dollar of Net Cash Proceeds generated with respect to such Asset Sale; and (b) For every Asset Sale occurring after January 31, 1997 involving real property, the Net Cash Proceeds of which are used (i) to reduce the Term Advances or (ii) after the repayment in full of the Term Advances to permanently reduce the Revolving Commitments pursuant to Section 2.04, the Maximum Borrowing Base Real Property Amount shall be increased by one Dollar multiplied by a factor of 0.67 for each Dollar of Net Cash Proceeds generated with respect to such Asset Sale.

Subject to the other provisions hereof, the Borrower may from time-to-time borrow, prepay (in whole or in part) and reborrow Swingline Advances. (A) Except as provided in the following clause (B) below, each request for a Swingline Advance shall be made pursuant to telephone notice to SocGen given no later than 11:00 a.m. (Dallas, Texas time) on the date of the proposed Swingline Advance, promptly confirmed by a completed and executed Notice of Borrowing telecopied to the Agent.

(B) The Borrower and the Banks agree that in the event any Swingline Advance is not repaid on the date due to SocGen, each Bank shall pay to the Agent its Pro Rata Share of such Swingline Advance and such payment shall be deemed to be a Prime Rate Advance made pursuant to such Bank's Revolving Commitment, whether made before or after termination of the Commitments, acceleration of the Advances, or otherwise, and whether or not the conditions precedent in Section 3.02 have been satisfied. The Agent shall give each Bank notice of such Mandatory Revolving Borrowing by 11:00 a.m. (Dallas, Texas time) on the date the Mandatory Revolving Borrowing is to be made. Each Bank shall make its Advance available to the Agent for the account of SocGen in immediately available funds by 1:00 p.m. (Dallas, Texas time) on the date requested, and the Borrower hereby irrevocably instructs SocGen to apply the proceeds of such Mandatory Revolving Borrowing to the payment of the outstanding Swingline Advances. 1.4.

In the case of a proposed Borrowing comprised of Eurodollar Rate Advances, the Agent shall promptly notify each Bank of the applicable interest rate under Section 2.06(b). Each Bank shall (i) in the case of all Revolving Borrowings other than Borrowings made on the same day as the day the Notice of Borrowing is received, before 11:00 a.m. (Dallas, Texas time) on the date of such Borrowing and (ii) in the case of Revolving Borrowings made on the same day as the date of the Notice of Borrowing or Mandatory Revolving Borrowings, before 1:00 p.m. (Dallas, Texas time), make available for the account of its Applicable Lending Office to the Agent at its address referred to in Section 9.02, or such other location as the Agent may specify by notice to the Banks, in same day funds, such Bank's Pro Rata Share of such Borrowing. After the Agent's receipt of such funds and upon fulfillment of the applicable conditions set forth in Article III, the Agent will make such funds available to the Borrower at its account with the Agent. (b) Conversions and Continuations. In order to elect to Convert or continue Advances comprising part of the same Revolving Borrowing or Term Borrowing under this Section, the Borrower shall deliver an irrevocable Notice of Conversion or Continuation to the Agent at the Agent's office no later than 11:00 a.m. (Dallas, Texas time) (i) on the Business Day of the proposed conversion date in the case of a Conversion of such Advances to Prime Rate Advances and (ii) at least three Business Days in advance of the proposed Conversion or continuation date in the case of a Conversion to, or a continuation of, Eurodollar Rate Advances. Each such Notice of Conversion or Continuation shall be in writing or by telecopier, specifying (i) the requested Conversion or continuation date (which shall be a Business Day), (ii) the Borrowing amount and Type of the Advances to be Converted or continued, (iii) whether a Conversion or continuation is requested, and if a Conversion, into what Type of Advances, and (iv) in the case of a Conversion to, or a continuation of, Eurodollar Rate Advances, the requested Interest Period. Term Advances may only be Converted or continued as Term Advances and Revolving Advances may only be Converted or continued as Revolving Advances. Swingline Advances may not be converted or continued. Promptly after receipt of a Notice of Conversion or Continuation under this paragraph, the Agent shall provide each Bank with a copy thereof and, in the case of a Conversion to or a Continuation of Eurodollar Rate Advances, notify each Bank of the applicable interest rate under Section 2.06(b). For purposes other than the conditions set forth in Section 3.02, the portion of Term Advances comprising part of the same Term Borrowing that are Converted to Term Advances of another Type shall constitute a new Term Borrowing and the portion of Revolving Advances comprising part of the same Revolving Borrowing that are Converted to Revolving Advances of another Type shall constitute a new Revolving Borrowing. (c) Certain Limitations. Notwithstanding anything in paragraphs (a) and (b) above: (i) each Borrowing (other than a Borrowing of Swingline Advances) shall be in an aggregate amount not less than $2,000,000 or greater multiples of $1,000,000, in the case of Eurodollar Rate Advances, or $1,000,000 or greater multiples of $100,000, in the case of Prime Rate Advances, and shall consist of Advances of the same Type made on the same day by the Banks ratably according to their respective Commitments. (e) Agent Reliance. Unless the Agent shall have received notice from a Bank before the date of any Revolving Borrowing or Mandatory Revolving Borrowing that such Bank will not make available to the Agent such Bank's Pro Rata Share of the Borrowing, the Agent may assume that such Bank has made its Pro Rata Share of such Borrowing available to the Agent on the date of such Borrowing in accordance with paragraph (a) of this Section 2.02 and the Agent may, in reliance upon such assumption, make available to the Borrower on such date a corresponding amount. If and to the extent that such Bank shall not have so made its Pro Rata Share of such Borrowing available to the Agent, such Bank and the Borrower severally agree to immediately repay to the Agent on demand such corresponding amount, together with interest on such amount, for each day from the date such amount is made available to the Borrower until the date such amount is repaid to the Agent, at (i) in the case of the Borrower, the interest rate applicable on such day to Advances comprising such Borrowing and (ii) in the case of such Bank, the Federal Funds Rate for such day. If such Bank shall repay to the Agent such corresponding amount and interest as provided above, such corresponding amount so repaid shall constitute such Bank's Advance as part of such Borrowing for purposes of this Agreement even though not made on the same day as the other Advances comprising such Borrowing. (g) Notes. The indebtedness of the Borrower to each Bank resulting from Revolving Advances owing to such Bank shall be evidenced by the Revolving Note of the Borrower payable to the order of such Bank in substantially the form of Exhibit A.
