(d) If Overnite Corporation shall determine that it is desirable for UPC, Overnite Corporation, or a member of the Overnite Consolidated Group to file a claim for refund or an amended return that in any way involves Federal Income Taxes or Unitary Income Taxes for any Pre-Offering Period, Overnite Corporation shall prepare and submit such proposed claim to UPC, together with a reasoned analysis of the merits of the proposed claim and a statement setting forth when the statute of limitations on filing such claim will expire, in sufficient time for UPC to act on such proposed claim. UPC shall reasonably consider and act on any such claim, provided either (i) such claim does not adversely affect UPC, or (ii) Overnite Corporation agrees, in a manner reasonably satisfactory in form and substance to UPC, to indemnify UPC from and against any Actual Loss that UPC may sustain as a result of the filing of such claim or amended return, the conduct of proceedings relating thereto and the allowance or disallowance (in whole or in part) thereof.

(e) To the extent Overnite Corporation’s obligations to indemnify UPC under Section 7.1(e) are involved, Overnite Corporation shall have the right to participate in any proceedings controlled by UPC related to the Section 338(h)(10) Elections, and to review all correspondence with the Taxing Authority relating to such proceedings.

Section 6.2. Notice of Examinations, Amended Returns, Protests and Litigations. Each Party shall promptly give notice to the other of any examination, inquiry, litigation, or proposed or actual assessment by a federal, state, local or foreign Taxing Authority covering any potential Tax liability where one Party may have a right to demand payment for such Tax from, or be indemnified by, the other Party.

Section 6.3. Record Retention. The UPC and Overnite Consolidated Groups shall comply with the record retention provisions of the Code, as interpreted by Treasury Regulations and relevant administrative rulings of the Internal Revenue Service.

Section 6.4. Remedies.

(b) In addition to the indemnification provisions of Section 7.4, if any Party fails to provide (i) any cooperation or information requested pursuant to Section 6.1 by the date reasonably specified by the other Party or (ii) any other information requested pursuant to this Agreement within a reasonable period, as determined in good faith by the requesting Party, then, without limiting any other remedy available to the requesting Party for breach of the obligations under this Agreement, the requesting Party shall have the right to engage an accounting firm of its choice to gather such information. Each Party agrees to permit such accounting firm full access to all appropriate records or other information in the possession of any member of such Party’s consolidated group or unitary group during normal business hours, and promptly to reimburse or pay directly all costs and expenses in connection with the engagement of such accountants.

The members of the UPC Consolidated Group shall be jointly and severally liable for and shall indemnify and hold Overnite Corporation and its Subsidiaries (including Motor Cargo) harmless from and against any Actual Loss suffered or other liability incurred as a result of the nonqualification of the merger consummated under the 2001 Motor Cargo Merger Agreement as a reorganization within the meaning of Section 368(a)(1)(A) and 368(a)(2)(D) of the Code for any reason other than an action taken or failure to act, in either case before or after the Offering Date, by the Overnite Consolidated Group or Overnite Unitary Group.

(d) The members of the UPC Consolidated Group shall be jointly and severally liable for and shall indemnify and hold the members of the Overnite Consolidated Group harmless from and against any Actual Loss and any Section 338(h)(10) Defense Cost suffered or incurred as a result of the invalidity or ineffectiveness (in whole or in part) of any of the Section 338(h)(10) Elections, if such invalidity or ineffectiveness is caused by an action or failure to act by a member of the UPC Consolidated Group (and not by an action or failure to act by any member of the Overnite Consolidated Group). For purposes of this Section 7.1(d), the retention by UPC of any of the Additional Shares shall not be considered an action or failure to act by a member of the UPC Consolidated Group.

(e) The members of the Overnite Consolidated Group shall be jointly and severally liable for and shall indemnify and hold the members of the UPC Consolidated Group harmless from and against any Actual Loss and any Section 338(h)(10) Defense Cost suffered or incurred as a result of the invalidity or ineffectiveness (in whole or in part) of any of the Section 338(h)(10) Elections, if such invalidity or ineffectiveness is caused by an action or failure to act by a member of the Overnite Consolidated Group (and not by an action or failure to act by any member of the UPC Consolidated Group).

(f) For purposes of this Article VII, the planning of the structure of the Acquisition and the Offering shall not be considered an action (or failure to act) by either Party.

The members of the Overnite Consolidated Group shall be jointly and severally liable for and shall indemnify and hold the members of the UPC Consolidated Group harmless from and against any Actual Loss suffered by the UPC Consolidated Group due to any failure of the Overnite Consolidated Group to comply with the requirements of Article VI of this Agreement. The members of the UPC Consolidated Group shall be jointly and severally liable for and shall indemnify and hold the members of the Overnite Consolidated Group harmless from and against any Actual Loss suffered by the Overnite Consolidated Group due to any failure of the UPC Consolidated Group to comply with the requirements of Article VI of this Agreement.

Section 7.5. Indemnity Payments. Any indemnity payment made under this Article VII shall be reduced to account for Tax Benefits realized by the indemnified Party by reason of the facts and circumstances giving rise to the indemnity payment and increased to account for Taxes incurred on the receipt of the indemnity payment, such that the indemnity payment made to the indemnified Party, when adjusted to take into account such Tax Benefits and Taxes, is equal to the amount required to be indemnified under the relevant section of this Article VII (for example, Actual Losses plus Section 338(h)(10) Defense Costs in the case of a Section 7.1(d) or 7.1(e) indemnity).

ARTICLE VIII

DISPUTES

Section 8.1. Negotiation. UPC and Overnite Corporation shall attempt in good faith promptly to resolve any dispute arising in connection with this Agreement. In the event of any such dispute, either Party may deliver a notice of dispute to the other Party explaining the issue in dispute and beginning the Negotiation Period. Within 90 Business Days of the receipt of such notice, the appropriate representatives of UPC and Overnite Corporation shall meet to attempt to resolve the dispute. If, within a reasonable time thereafter, the dispute is not resolved by agreement of the Parties, or if one of the Parties fails or refuses to negotiate the dispute, the issue shall be settled by arbitration pursuant to this Article VIII. Either Party may terminate the Negotiation Period at any time after 120 Business Days have elapsed since the beginning of the Negotiation Period by giving notice to the other Party. Nothing in this Article VIII shall be construed to extend the time periods set forth in this Agreement during which any Party may make a payment, deliver a notice, provide information, grant or withhold approval or consent or take any other action.

Section 8.2. Arbitration Procedure. Either Party may initiate arbitration by giving the other Party written notice within one year following the end of the Negotiation Period. The place of arbitration shall be St. Louis, Missouri, but not at the offices of any Party. Any time period or deadline specified in this Article VIII may be extended by mutual agreement of the Parties.

Section 8.3. Selection of Arbitrators. UPC and Overnite shall make every reasonable effort to jointly select the arbitrator. If UPC and Overnite are unable to agree on the designated arbitrator within 20 Business Days after either Party gives notice of arbitration, then the arbitration shall be by a panel of three arbitrators. UPC and Overnite shall each appoint one arbitrator. The two arbitrators so appointed shall appoint the third arbitrator. If either UPC or Overnite shall fail to appoint an arbitrator within such 20 Business Day period, the arbitration shall be by the sole arbitrator appointed by the other Party. Whether jointly selected by UPC and Overnite or otherwise, each arbitrator shall be an attorney or accountant who is generally recognized in the Tax community as a qualified and competent Tax practitioner.

Section 8.4. Settlement Proposals. Each Party shall present an overall settlement proposal to the arbitrator or arbitrators which shall encompass all issues to be resolved. The proposals from each Party shall set the outer limits of the range within which the arbitrator or arbitrators may make a determination as to the appropriate settlement result. If such appropriate settlement result is less than $250,000 in amount, it shall be deemed to be zero, unless the arbitrator or arbitrators determine that there was not a reasonable basis for the position of the non-prevailing Party. If such appropriate settlement result is not less than $250,000 in amount, $250,000 shall be subtracted from such appropriate settlement result by the arbitrator or arbitrators in reaching their determination of the amount to be awarded one of the Parties, unless the arbitrator or arbitrators determine that there was not a reasonable basis for the position of the non-prevailing Party.

Section 8.5. Arbitrator’s Determination Final. The determination made by the arbitrator or arbitrators shall be conclusive and binding upon the Parties and shall not be subject to appeal, except in the case of manifest factual or mathematical error, or fraud or bias on the part of the arbitrator or arbitrators. The arbitrator or arbitrators shall also determine which Party shall bear the costs of the arbitration process, including counsel fees, and may allocate such costs between the Parties in any manner.

ARTICLE IX

MISCELLANEOUS

Section 9.1. Sharing of Information. Each Party shall provide the other Party with all relevant Tax accounting information and portions of returns, elections, amended returns, claims for refund, consents, and extensions of the statute of limitations which each files on behalf of the Overall Consolidated Group (or any members thereof) for any periods which are reasonably requested. Such information shall be provided to the other Party within 30 Business Days of the request.

Section 9.2. Confidentiality. The Parties agree that, except as otherwise expressly agreed in writing, any information furnished to the other Party pursuant to this Agreement is confidential. Except to the extent required for the proper filing of returns or resolving a dispute, audit, or litigation, the Parties covenant not to disclose, and not to permit disclosure of, such information to persons other than their own auditors or Tax advisors. Such auditors or Tax advisors shall be instructed to maintain a level of confidentiality with respect to the information as if the furnishing Party were their client. Notwithstanding anything herein or in the Stock Purchase and Indemnification Agreement to the contrary, any Party (and any employee, representative, or other agent of any Party) may disclose to any and all persons, without limitation of any kind, the tax treatment and tax structure of the Acquisition, the Offering, and any other transaction contemplated by this Agreement and all materials of any kind (including opinions or other tax analyses) that are provided to it relating to such tax treatment and tax structure; provided, however, that any such information is required to be kept confidential to the extent necessary to comply with any applicable federal and state securities laws.

Section 9.3. Successors. This Agreement is being entered into by the Parties on behalf of themselves and each member of the UPC Consolidated Group and the Overnite Consolidated Group, respectively. This Agreement shall bind each member of the UPC Consolidated Group and the Overnite Consolidated Group, and shall continue to bind each such member whether or not it remains affiliated with UPC or Overnite Corporation, as the case may be, and shall be deemed to have been readopted and affirmed on behalf of any corporation which, subsequent to the date hereof, becomes a member of the UPC Consolidated Group or the Overnite Consolidated Group. This Agreement shall be binding upon and inure to the benefit of any successor to the Parties (by merger, consolidation, liquidation, acquisition of all or substantially all of a Party’s assets, or otherwise) to the same extent as if the successor had been an original party to this Agreement.

Section 9.4. Governing Law. This Agreement shall be governed by and construed in accordance with the laws of the State of Delaware, without regard to the conflict-of-laws principles thereof.

Section 9.5. Headings. The headings in this Agreement are for convenience only and shall not be deemed for any purpose to constitute a part of or to affect the interpretation of this Agreement.

Section 9.6. Notices. Except as otherwise specifically provided in this Agreement or agreed to in writing by UPC and Overnite Corporation, all notices, claims, requests, demands and other communications under this Agreement shall be in writing and shall be deemed to have been duly given either (i) when transmitted by fax or electronic mail, receipt of which is acknowledged by fax or electronic mail, provided a confirming copy is simultaneously mailed (registered or certified mail,

(b) If, due to any change in applicable law or regulations or their interpretation by any court of law or other governing body having jurisdiction subsequent to the date of this Agreement, performance of any provision of this Agreement or any transaction contemplated thereby shall become impracticable or impossible, the parties hereto shall use their commercially reasonable efforts to find and employ an alternative means to achieve the same or substantially the same result as that contemplated by such provision.

Section 9.8. Severability. If any provision of this Agreement is held to be unenforceable for any reason, it shall be adjusted rather than voided, if possible, in order to achieve the intent of the Parties to the maximum extent practicable.
