SERVICES AGREEMENT

Exhibit 10.6

SERVICES AGREEMENT

THIS SERVICES AGREEMENT (this “Agreement”) is made and entered into as of the              day of                     , 2003 by and between Union Pacific Corporation, a Utah corporation, including all of its subsidiaries and affiliates (“UPC”), and Overnite Corporation, a Virginia corporation, including all of its now or hereafter existing subsidiaries and affiliates (“Overnite”).

WHEREAS, UPC intends to sell its entire interest in Overnite Holding, Inc., a Delaware corporation (“OHI”), in connection with an underwritten initial public offering (the closing of which is hereafter referred to as the “Offering”);

WHEREAS, immediately prior to the Offering, Overnite will acquire from UPC all of the outstanding common stock of OHI in exchange for, inter alia, all of the outstanding common stock of Overnite (the “Divestiture Transaction”), such that OHI will become a wholly-owned subsidiary of Overnite and, immediately following the Offering, Overnite will be a publicly-owned company;

WHEREAS, Overnite Transportation Company, a Virginia corporation (“OTC”), and Motor Cargo Industries, Inc., a Utah corporation (“Motor Cargo”), each a wholly-owned, indirect subsidiary of OHI, will each become a wholly-owned, indirect subsidiary of Overnite immediately following the Divestiture Transaction;

WHEREAS, UPC historically provided certain corporate and administrative services to its subsidiaries, including OHI, OTC, and Motor Cargo; and

WHEREAS, UPC and Overnite desire that UPC continue to provide certain services to Overnite and its subsidiaries following the Offering and the Divestiture Transaction pursuant to the terms and conditions of this Agreement.

NOW, THEREFORE, in consideration of the mutual promises and covenants herein contained and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties to this Agreement, intending to be bound hereby, agree as follows:

1. Services. Following the Offering and the Divestiture Transaction, UPC will provide or cause to be provided to Overnite, those corporate and administrative services described in Exhibit A hereto (the “Services”), as requested by Overnite from time to time. The scope of the Services may be adjusted by the mutual agreement of the parties hereto.

2. Charges for Services. As consideration for the Services provided hereunder, Overnite agrees to pay the following fees and expenses to UPC:

(a) Fees for Services performed for Overnite by a vendor, contractor or similar third party (other than UPC) shall be equal to the final invoiced costs charged by such third party to UPC for the performance of such Services. With respect to all other Services provided by UPC, Overnite will pay to UPC a fee equivalent to $150 per hour, which includes, without limitation, a reasonable allocation of direct and indirect overhead costs (including, without limitation, employee salaries, benefits and other costs) In addition, Overnite will pay reasonable travel and other out-of-pocket expenses incurred in connection therewith. All travel and out-of-pocket expenses of UPC made in accordance with the then effective policies of UPC governing such expenses will be deemed reasonable and may not be subject to any dispute. Notwithstanding the foregoing, the parties agree that there shall not be any charges for Incidental Services provided directly by UPC. For purposes of this Agreement, the term Incidental Services shall mean advice or assistance provided to Overnite by UPC via telephone or electronic mail (excluding the preparation or review by UPC of any agreements or other documents delivered by or included in any electronic mail) which shall not exceed a total of five hours per month for each of the service categories set forth on Exhibit A hereto.

1

(b) If any additional Services not specifically provided for herein are provided to Overnite by UPC, Overnite will pay the fees and expenses for such services in accordance with Section 2(a) of this Agreement.

3. Payments.

(a) UPC shall submit to Overnite by the 10th working day of each quarter an invoice for all charges associated with Services provided during the preceding quarter, including any other amounts payable in respect of the preceding quarter. All invoices shall describe in reasonable detail the Services provided and the charges associated therewith, any related adjustments and any other amounts that are payable. Except as provided in subparagraph (b) below, Overnite shall remit payment in full for all charges invoiced on or before the last business day of the month in which the invoice is received. Payment of all invoices shall be made by wire transfer of immediately available funds to an account or accounts designated by UPC. Any late payment shall bear interest at the rate of 0.5% per month or fraction thereof until paid.

(b) In the event of a dispute as to an invoiced amount, Overnite shall promptly pay all undisputed amounts, but shall be entitled to withhold amounts in dispute, and shall promptly notify UPC of such dispute and the basis therefor. The parties agree to provide each other with sufficient records and information to resolve such dispute and, without limiting the rights and remedies of the parties hereunder, to negotiate in good faith a resolution thereto. Notwithstanding this clause (b), the late payment interest provision in Section 3(a) shall apply to all such withheld amounts that are ultimately determined to be due and payable, which amounts, including any interest, shall be promptly remitted to UPC in the manner provided herein.

(c) In the event that UPC provides to Overnite any one-time services not contemplated by this Agreement, UPC may invoice Overnite separately for all reasonable fees and expenses for such services, which fees and expenses will be calculated in accordance with Section 2(a) of this Agreement. In connection with such one-time or other similar extraordinary projects or services undertaken or provided by UPC, UPC may invoice Overnite separately for such services on a monthly basis on the first business day of each month and Overnite shall remit payment in full for all fees invoiced on or before the last business day of the month in which the invoice is received, subject to the invoicing provisions set forth in Sections 3(a) and 3(b) above.

4. Term of Agreement. The term of this Agreement shall commence immediately following the Offering and the Divestiture Transaction and shall continue for a period of 18 months unless terminated by agreement of the parties hereto (except with respect to the services identified in Paragraph 7 of Exhibit A, which shall be provided until December 31, 2004). Notwithstanding the foregoing this Agreement shall become terminable (i) at any time by Overnite upon delivery of written notice to UPC with respect to any Services or any part thereof or (ii) by UPC immediately upon the acquisition by any third party (including any group of investors or acquirors acting in concert with the intent to acquire or acquire control of Overnite) of all or substantially all of the assets of Overnite or a majority of the issued and outstanding common stock of Overnite or that amount of any other voting security or securities of Overnite that would constitute a majority of the voting securities of Overnite or other similar disposition or transaction. Termination under this Section 4 or otherwise shall have no effect on the obligations of the parties to provide Services prior to the effective date of such termination or to make payments in respect of charges incurred in connection therewith or which relate to events occurring prior to such date.

5. Performance of Services.

(a) UPC shall perform the Services or cause the Services to be performed with the same degree of care, skill, timeliness and prudence customarily exercised with respect to its own operations. It is understood and agreed that the Services will be substantially identical in nature and quality to the Services performed by UPC for OHI and its subsidiaries during the year prior to the commencement of the term of this Agreement, except with respect to such services required to effect the Divestiture Transaction and the Offering.

2

(b) Each party acknowledges that the Services will be provided only with respect to the businesses of Overnite as such businesses exist immediately following the Offering and the Divestiture Transaction or as otherwise mutually agreed by the parties. Services will not be requested for the benefit of any entity other than Overnite. Overnite agrees that it will use the Services only in accordance with all applicable federal, state and local laws, regulations and tariffs and in accordance with the reasonable conditions, rules, regulations and specifications which are or may be set forth in any manuals, materials, documents or instructions of UPC. UPC reserves the right to take all actions, including the termination of any Services or part thereof, in order to ensure that the Services are provided in accordance with any applicable laws, regulations and tariffs.

(c) Any input or information needed by either party to perform or utilize the Services pursuant to the provisions of this Agreement shall be provided by the other party or its subsidiaries, as the case may be, in a manner consistent with the practices employed by the parties during the year prior to the Offering. Should the failure by Overnite to provide such input or information render the performance of the Services impossible or unreasonably difficult, UPC may, upon reasonable notice, refuse to provide such Services.

6. Liability and Indemnification. Except as provided below, UPC and all of its directors, officers, agents and employees shall have no liability, whether direct or indirect, in contract, tort or otherwise, under this Agreement for any damage, loss or other harm (including, without limitation, out-of-pocket expenses and fees and disbursements of counsel) of any type suffered by Overnite or any third party in connection with the performance or non-performance of this Agreement or the Services contemplated hereby or any action or in-action of any of the indemnified parties in connection with the foregoing, except for any such damage, loss or other harm directly caused by or directly resulting from the gross negligence or willful misconduct of UPC in connection with the performance or non-performance of this Agreement or the Services contemplated hereby or the action or inaction of any of the indemnified parties in connection with the foregoing. In the event of a third party claim, Overnite, including its successors and assigns, for itself and on behalf of all of its subsidiaries and affiliates, including their respective successors and assigns, shall indemnify, defend and hold harmless UPC and all of its directors, officers, agents and employees from and against any and all such damages, losses and other harms (including, without limitation, out-of-pocket expenses and fees and disbursements of counsel) caused by or arising out of the performance or non-performance of this Agreement or the Services contemplated hereby or the actions or in-actions of any of the indemnified parties in connection with the foregoing other than any such damage, loss or other harm directly caused by or directly resulting from the gross negligence or willful misconduct of UPC in connection with the performance or non-performance of this Agreement or the Services contemplated hereby or the actions or in-actions of any of the indemnified parties in connection with the foregoing. The total liability of UPC under this Section 6 will not under any circumstances exceed the aggregate amount of fees paid to UPC by Overnite. Notwithstanding any other provision of this Agreement, UPC shall have no liability for (i) any lost profits or any incidental, consequential, special, indirect or similar damages of any kind or nature whatsoever of Overnite or any third party (including the fees and expenses of counsel) or (ii) the acts or omissions of any third party (other than UPC) that provides Services hereunder. This Section 6 shall survive the termination of this Agreement until such time as the obligations of the parties (including their respective successors and assigns) set forth in this Section 6 have been fully satisfied.

7. Confidentiality. The parties each agree to hold in trust and maintain confidential, and, except as required by law or applicable rules and regulations promulgated thereunder or by court order or other legal process, not to disclose to others without first obtaining the prior written approval of the other party, any information received by it from the other party or developed or otherwise obtained by it under this Agreement, including all information resulting from the provision or utilization of the Services hereunder (collectively, the “Information”). At the time of termination of this Agreement in whole or in part, each party shall, within 90 days after the effective date of such termination, return to each other all written Information that it obtained and shall not retain or allow any third party to retain photocopies or other reproductions of such Information, provided that (i) the parties may retain any Information to the extent reasonably needed to comply with applicable tax, accounting or financial reporting requirements or to resolve any legal issues identified at the time of termination, and (ii) in the case of a partial termination of this Agreement, the parties may retain any Information required to perform or utilize any remaining Services covered by this Agreement. Alternatively, each party may, upon

3

receipt of the written consent of the other party, destroy such Information instead of returning the same pursuant to the foregoing sentence. The obligations set forth in this Section 7 shall not apply to any Information which is shown by either party to be or have become knowledge generally available to the public other than through the acts or omissions of such party.

8. Assignment. Neither party shall assign or transfer any of its rights or delegate any of its obligations under this Agreement without first obtaining the prior written consent of the other party, which consent may be withheld by such other party in its sole discretion; provided that UPC shall be permitted to cause any Services to be provided or caused to be provided by UPC through one or more third parties selected by UPC; and provided further that the selection of any third party by UPC shall be subject to the prior written consent of Overnite (which shall not be unreasonably withheld or delayed) unless such third party shall have provided the same or similar Services to UPC or its affiliates at any time during the 12 months immediately preceding the Offering. This Agreement shall be binding upon and inure to the benefit of the parties hereto and their successors and permitted assigns.

9. Notices. All notices and other communications hereunder shall be in writing and shall be delivered in person, by United States mail, certified, return receipt requested, postage prepaid, by express mail by a nationally recognized carrier, or by facsimile transmission (provided, if sent by facsimile transmission, such notice shall also be sent by one of the other methods provided under this section within 24 hours after initially sent by facsimile transmission) to the following:
