(b) Each Union Pacific Stock Option that is intended to be an incentive stock option under Section 422 of the Internal Revenue Code of 1986, as amended (the “Code”), and that was granted before 1996 shall remain outstanding and shall continue to vest (or become exercisable) in accordance with its original terms as if the Employee’s employment with Overnite or an affiliate after the Effective Date was employment with Union Pacific; provided, however, that such options shall expire and shall not be exercisable after the earlier of (i) the original expiration date of such option and (ii) the date that is three months after the Effective Date.

(c) Each Union Pacific Stock Option that is intended to be an incentive stock option under Section 422 of the Code, and that was granted after 1995 shall remain outstanding and shall continue to vest (or become exercisable) in accordance with its original terms as if the Employee’s employment with Overnite or an affiliate after the Effective Date was employment with Union Pacific; provided, however, that such options shall expire and shall not be exercisable after the earlier of (i) the original expiration date of such option and (ii) the fifth anniversary of the Effective Date and shall by virtue of this Section 1(c) become nonqualified options under the Code.

(d) Each Union Pacific Stock Option that is not intended to be an incentive stock option under Section 422 of the Code, shall remain outstanding and shall continue to vest (or become

exercisable) in accordance with its original terms as if the Employee’s employment with Overnite or an affiliate after the Effective Date was employment with Union Pacific; provided, however, that such options shall expire and shall not be exercisable after the earlier of (i) the original expiration date of such option and (ii) the fifth anniversary of the Effective Date.

2. Retention Shares

Each Retention Share that is outstanding on the Effective Date and that is held by an Employee shall be vested and transferable as of the Effective Date. The term “Retention Share” means a “Retention Share” as defined in the Union Pacific 2001 Stock Incentive Plan.

Awards under the Union Pacific 2001 Long-Term Plan (the “LTP”), whether denominated as retention shares, retention stock units, cash awards or otherwise, held by Employees on the Effective Date (the “LTP Awards”) shall remain outstanding, and Union Pacific waives as of the Effective Date all employment requirements set forth in the LTP All of the LTP Awards shall be paid in accordance with the 2001 Long-Term Plan to the extent that the applicable Union Pacific performance objectives are achieved.

(a) Union Pacific agrees to guarantee payment of the benefit accrued under Overnite’s Supplemental Executive Retirement Plan (“SERP”) to each of the Employees identified on Schedule I to this Agreement (and their respective beneficiaries in accordance with the applicable terms of the SERP) in the event Overnite fails to pay all or part of the benefit payable under the SERP to such Employee or beneficiary: provided, (i) Union Pacific’s obligation under this Section 4 with respect to any Employee shall not exceed the benefit accrued under the SERP as of December 31, 2003 and shall be determined using the terms of the SERP as of the Effective Date and (ii) the obligation of Union Pacific to make payments under this Section 4 with respect to any Employee (or their beneficiary) will be reduced by the amount of all payments made to such Employee (or their beneficiary) directly or indirectly by Overnite pursuant to the terms and conditions of the SERP or in satisfaction thereof. Any payment made by Union Pacific pursuant to this Section 4 shall be made directly to the Employee or their beneficiary, as appropriate.

(b) In the event that Overnite fails or refuses to pay all or any part of a benefit or benefits to any Employee (or their beneficiary) to which they are entitled under this Section 4 after any such Employee or beneficiary has in good faith submitted a claim to Overnite for such benefit or benefits (and such Employee has not caused the failure or refusal by Overnite to make any such payment), Union Pacific shall make such payments as are required by Section 4(a). Union Pacific, in addition to all other rights or remedies available at law, in equity or otherwise, including, without limitation, legal subrogation, shall be subrogated to the rights of any Employee (or their beneficiary) with respect to any payments made to any Employee (or their beneficiary) pursuant to Section 4(a) such that Union Pacific may recover directly from either or both of Overnite and OTC (or their respective successors and assigns) the aggregate amount of any such payments.

Union Pacific, in addition to all other remedies available at law, in equity or otherwise, including, without limitation, legal subrogation, shall be subrogated to the rights of any Employee (or their beneficiary) with respect to any payments made to any Employee (or their beneficiary) pursuant to Section 5(a) such that Union Pacific may recover directly from either or both of Overnite or OTC (or their respective successors and assigns) the aggregate amount of any such payments.

6. Other Deferred Compensation Plans

Union Pacific agrees that an Employee’s employment with Overnite or an affiliate will be deemed continued employment under the plans for purposes of vesting and determining the date on which distributions will commence under the nonqualified deferred compensation plans maintained by Union Pacific; provided, however, that an Employee shall not accrue any additional benefits (except for gains or losses attributable to investments) under such plans on account of employment with Overnite or an affiliate after the Effective Date. Union Pacific agrees that it remains liable for the payment of benefits to Employees under such nonqualified deferred compensation plans; provided, however, that the obligation of Union Pacific under this Section 6 with respect to any individual covered under this Section 6 shall be adjusted to reflect any subsequent gains or losses attributable to investments. Notwithstanding the foregoing, Union Pacific waives as of the Effective Date all employment requirements set forth in the plans.
