Supplemental Basic Compensation................................... 1 CNF INC. 2005 SUPPLEMENTAL EXCESS RETIREMENT PLAN CNF Inc. (the "Company") maintains a Supplemental Excess Retirement Plan (the "Prior Plan") for the purpose of providing key executives of the Company with retirement benefits in excess of those benefits provided under the CNF Inc. Retirement Plan (the "Retirement Plan") and the EWA Pilots' Retirement Plan. The Company has amended the Prior Plan to limit it to pre- 2005 accruals. As a consequence, the Prior Plan need not meet the requirements of Section 409A of the Internal Revenue Code (the "Code"). The Company hereby adopts this 2005 Supplemental Excess Retirement Plan (the "Plan") to provide for post-2004 accruals in such a way as to meet the requirements of Section 409A. ARTICLE 1 Effective Date; Tax and ERISA Status 1.1 Effective Date; Plan Year 1.1-1 The Plan shall be effective January 1, 2005. 1.1-2 The "Plan Year" of the Plan shall be the calendar year, the same as for the Retirement Plan. 1.2 Tax and ERISA Status 1.2-1 The Plan is not intended to qualify under Section 401(a) of the Code. 1.2-2 The Plan is intended to constitute a plan of deferred compensation for a select group of management or highly compensated employees. ARTICLE 2 Application to the Company and Affiliates 2.1 Affiliates 2.1-1 The Company sponsors the Plan for its employees and for the employees of any Affiliate that is an Employer under the Plan. 2.1-2 "Affiliate" means a corporation, person or other entity that is one of the following: (a)A member, with an Employer, of a controlled group under Section 414(b) of the Code. (b)A member, with an Employer, of a group of trades or businesses under common control under Section 414(c) of the Code. (c)A member, with an Employer, of an affiliated service group under Section 414(m) of the Code. (d)A member, with an Employer, of a group of employers required to be aggregated under Section 414(o) of the Code. 2.1-3Employer "Employer" means the Company and any Affiliate that is an Employer under the Retirement Plan. A list of Employers is attached to the Retirement Plan. ARTICLE 3 Participation and Benefits 3.1 Participation 3.1-1Any employee of Employer who participates in the Retirement Plan shall be eligible for this Plan if the employee has either of the following: (a)Compensation deferred under an elective nonqualified deferred compensation plan of Employer. (b)Compensation, as defined in a Retirement Plan, in excess of the limit imposed by Section 401(a)(17) of the Code. 3.1-2"Participant" means any employee of Employer who satisfies the conditions of 3.01-1. 3.2Amount of Benefit 3.2-1Subject to the limitations of Section 3.02-4, a Participant shall have a retirement benefit under the Plan equal to the excess of (a) over (b) based on the Retirement Plan covering the Participant: (a)The "Basic Benefit," as defined in the Retirement Plan, the Participant would have had if Supplemental Basic Compensation were used in place of "Basic Compensation" as defined in the Retirement Plan. (b)The Participant's actual Basic Benefit under the Retirement Plan. 3.2-2"Supplemental Basic Compensation" means a Participant's Basic Compensation increased to include: (a)Any compensation deferred by the Participant pursuant to a nonqualified deferral arrangement that, but for such arrangement, would have been included in Basic Compensation; and (b)Any compensation that would have been included in Basic Compensation but for the limitations imposed by Section 401(a)(17) of the Code. An amount described in (a) shall be counted as Supplemental Basic Compensation in the year in which it would have been paid but for such deferral. An amount described in (b) shall be counted as Supplemental Basic Compensation in the year paid. 3.2-3If the surviving Spouse of a Participant is entitled to a pre- retirement survivor annuity under a Retirement Plan, the Spouse shall have a benefit under this Plan calculated by applying the provisions of the Retirement Plan for the amount of pre-retirement survivor annuity to an accrued benefit of the Participant on the date of death equal to the excess benefit described in 3.02-1. For purposes of the Plan, the term "Spouse" has the meaning set forth in the Defense of Marriage Act of 1996 (P.L. 104-199), as amended. (As of January 1, 2005, this definition is a legal union between one man and one woman as husband and wife.) 3.2-4The retirement benefit described in 3.02-1 shall be the sum of the retirement benefit provided by the Plan and the retirement benefit provided by the Prior Plan. The Prior Plan applies to benefits accrued as of December 31, 2004. The Plan applies to benefits accrued after December 31, 2004. The Committee shall determine accrued benefits as of December 31, 2004 in a manner consistent with Section 409A of the Code, the regulations thereunder, and any additional guidance provided by the Treasury Department. 3.3Vesting A Participant's retirement benefit under this Plan shall become vested at the same time as the Participant's retirement benefit under the Retirement Plan becomes vested. If the Participant forfeits retirement benefits due to having five consecutive "Break in Service Years" as defined in the Retirement Plan, the Participant's benefits under this Plan also shall be forfeited. 3.4Time and Form of Benefits 3.4-1A retirement benefit or preretirement survivor annuity under this Plan shall be paid at the same time and in the same form as the corresponding benefit is paid under the Retirement Plan; provided, however that, if such payment would cause the Plan to fail to meet the requirements of Section 409A of the Code, the retirement benefit or preretirement survivor annuity under this Plan shall be paid at the time and in the form the corresponding benefit would have been paid under the Retirement Plan if - (a)The Participant had elected to commence benefits under the Retirement Plan at the earliest time permitted but not before the time the Participant had incurred a separation from service, as that term is used in Section 409A(a)(2)(A)(i) of the Code. (b)If the Participant has no Spouse when benefits would have commenced, benefits were paid in the form of the "Basic Benefit" as defined in the Retirement Plan. (c)If the Participant has a Spouse when benefits would have commenced, benefits were paid in the form of a life annuity with half payments continued to the Spouse. (d)The Participant did not waive the pre-retirement survivor annuity. 3.4-2If a Participant dies after benefits under this Plan commence, survivor benefits, if any, shall be paid in accordance with the form of benefit being paid to the Participant. 3.4-3If the Actuarial Equivalent lump sum value of a benefit payable to a Participant or surviving Spouse is less than $10,000 at the time payment is to commence, payment shall be made at that time in a lump sum and not in the form provided in 3.04-1 or 3.04-2.
