SECTION 2 ADMINISTRATION 2.1 Management Committee. The Plan shall be administered by a management committee (the "Management Committee") consisting of such executives of the Company as the Chief Executive Officer of the Company shall designate. Subject to review by the Compensation and Nominating Committee of the Board, the Management Committee shall have the complete authority and power to interpret the Plan, prescribe, amend and rescind rules relating to its administration, select eligible Participants, determine a Participant's (or Beneficiary's) right to a payment and the amount of such payment, and to take all other actions necessary or desirable for the administration of the Plan. All actions and decisions of the Management Committee shall be final and binding upon all Participants and Beneficiaries. No member of the Management Committee shall vote on any matter that pertains solely to himself or herself. -3- 6 SECTION 3 PARTICIPANTS 3.1 Participants. The Management Committee shall determine and designate the executives of the Company and other key employees of the Employers who are eligible to defer Base Salary under the Plan (the "Participants"). Participants will be limited to those employees who, because of their management or staff positions, have the principal responsibility for the management, direction and success of the Company as a whole or a subsidiary or a particular business unit thereof. Directors of the Company who are full-time executives of the Company shall be eligible to participate in the Plan. Each Participant must be a "member of a select group of management" or "highly compensated," as those terms are defined in Section 201(2) of the Employee Retirement Income Secuirty Act of 1974, as amended. Further, a Participant shall not be eligible to make deferrals under the Plan with respect to any year unless the Participant has also elected to make such year 401(k) contributions to the Company's qualified defined contribution plan at the highest contribution rate permitted under that plan and any reduction in his or her 401(k) contribution rate under such qualified plan prior to making the maximum 401(k) contribution for that year as permitted by the terms of the qualified plan shall result in the automatic suspension of the Participant's deferrals under this Plan for the remainder of that year. SECTION 4 BENEFITS 4.1 Voluntary Deferrals. Before January 1 of any year (or, with respect to employees who first become Participants during a year, on or before the date on which they become Participants) each Participant may elect to have the payment of all or a portion of his or her Base Salary for that year (or, if later, so much of the year as commences on the day following the date on which the employee becomes a -4- 7 Participant) deferred until his or her Termination. The election shall be irrevocable and shall be made on a form prescribed by the Management Committee, which shall govern the amount deferred, the form of its payment pursuant to Section 4.8 following the Participant's Termination, and, except as provided below, the investment of the Participant's Memorandum Account for such deferral period pending its payment. A Participant's deferral election shall apply only to Base Salary earned during that calendar year or partial year, as the case may be. If a Participant has not made a deferral election, the Base Salary payable to him or her for that year shall be paid in accordance with the Employer's normal payroll practices. 4.2 Special Deferrals. The Management Committee may, in its discretion, approve deferred payments ("Special Deferrals") as follows. Before January 1 of any year (or, with respect to employees who first become Participants during a year, on or before the date on which they become Participants) each Participant may elect to have the payment of all or a portion of his or her Base Salary for that year (or, if later, so much of the year as commences on the day following the date on which the employee becomes a Participant) deferred until a date or dates specified by the Management Committee, which, with respect to any Special Deferral invested in Phantom Stock, must be more than six months after the effective date of such deferral. The Participant's election shall be irrevocable and shall be made on a form prescribed by the Management Committee. A Participant's Special Deferral election shall apply only to Base Salary earned during that calendar year or partial year, as the case may be. If a Participant has not made a Special Deferral election, the Base Salary paid to him or her for that year (or partial year) shall be paid in accordance with Section 4.1. 4.3 Automatic Deferrals. If the Management Committee determines that all or part of the Base Salary to be paid to a Participant for a year would be -5- 8 nondeductible by the Company or a subsidiary for Federal tax purposes due to the limitations of Section 162(m) of the Internal Revenue Code, so much of the Base Salary that would not be deductible that year shall be deferred automatically and, unless the Management Committee, in its sole discretion, directs otherwise, credited to the Participant's Automatic Memorandum Account, which, pursuant to the Participants' election, shall be invested and payable as follows; (a) invested in the Interest Account and payable in the first year or years in which the Management Committee, in its sole discretion, determines either such payment(s) would be deductible or to forego the deduction; (b) invested in the Interest Account and payable upon the Participant's Termination; or (c) invested in the Company Stock Account and payable upon the Participant's Termination. A Participant's election must be made prior to the deferral date and, if (b) or (c) is elected, the election must also specify the form in which the Account is to be paid as provided in Section 6.9. If the Participant does not timely make an election with respect to an automatic deferral, he or she shall be deemed to have elected option (a) above. Automatic Memorandum Accounts are payable only in cash. 4.4 Memorandum Accounts. Each year the Company shall establish a ledger or notional account (the "Memorandum Account") for each Participant who has elected to defer payment of his or her Base Salary that year for the purpose of reflecting the Company's obligation to pay the deferred Base Salary for such year as specified pursuant to Section 4.8; provided, however, that all Memorandum Accounts established for a Participant that are to be paid in the same manner, i.e., a lump sum, 60 installments or 120 installments, may be combined into a single Memorandum Account. Similarly, a separate Special Memorandum Account shall be established for each Special Deferral for each Participant; however, all Special Deferrals of a Participant that are to be paid at the same time and in the same manner may be -6- 9 combined into a single Special Memorandum Account. In addition, a separate Automatic Memorandum Account shall be established for each automatic deferral made pursuant to Section 4.3 with respect to a Participant. 4.5 Investment of Accounts. Except as provided below, each Account shall accrue interest on the deferred Base Salary credited to such Account from the date such Base Salary is credited to the Account through the date of its distribution (the "Interest Account"). Such interest shall be credited to the Interest Account at the end of each calendar quarter or such other periods as may be determined by the Management Committee. The Management Committee shall determine, in its sole discretion, the rate of interest to be credited periodically to the Interest Accounts. With respect to an election to defer (or an automatic deferral of) Base Salary for any year beginning after 1993, a Participant may irrevocably request that the Management Committee credit all or a specified percentage of his or her Base Salary deferred that year in shares of Phantom Stock; however, the Management Committee shall not be obligated to honor any such Participant's request. If the Management Committee elects to honor any such request, it shall establish a separate notional subaccount for such Participant under his or her Account, which shall be credited with whole and fractional shares of Phantom Stock periodically as of the payroll dates of the deferrals in such year, and with phantom (notional) dividends with respect to the Phantom Stock, which shall be credited as being reinvested in additional shares of Phantom Stock (the "Company Stock Account"). All credits and debits to the Company Stock Account shall be made based on the Fair Market Value per share of the Company's common stock on the applicable date. If the Management Committee chooses to not honor any Participant's request to invest his or her Account in shares of Phantom Stock, the Participant's deferral automatically shall be held in the Interest Account. -7- 10 4.6 Special Phantom Stock Investment Elections. Each Participant who has an Account under the Plan on October 1, 1994 (including with respect to deferrals made in 1994) shall be given a one-time irrevocable election to request that all or a specified percentage of his or her Account balances as of that date, as elected by the Participant, be invested in the Company Stock Account; however, the Management Committee shall not be obligated to honor any such request. This election shall be in such form as the Management Committee shall establish, and must be made prior to October 1, 1994. 4.7 Change in Section 16(b) Rules. Notwithstanding anything in the Plan to the countrary, if the rules promulgated under Section 16(b) of the Securities Act of 1934, as amended, are amended or interpreted by the Securities and Exchange Commission to permit "insiders" to make investment changes with respect to their accounts under cash only type of plans like the Plan, the Management Committee, in its sole discretion, may amend the Plan in any manner it deems appropriate to allow Participants the ability to request, from time to time, investment changes with respect to their future deferrals and/or their existing Account balances under the Plan and may also add additional notional subaccounts under the Plan for such other investments as the Management Committee deems appropriate to offer under the Plan. 4.8 Payment of Accounts. Except as provided below, upon a Participant's Termination or on any Special Deferral payment date, the Company shall pay to such Participant (or to his or her Beneficiary in case of the Participant's death) an amount in cash equal to the balance then credited to his or her affected Account(s) as follows: (a) a lump sum payment; or (b) in 60 consecutive substantially equal monthly installments; or (c) in 120 consecutive substantially equal monthly installments, -8- 11 whichever form of payment has been elected by the Participant. However, if a Participant elects to receive the distribution of a Company Stock Account in installments, his or her Company Stock Account automatically shall be converted into an Interest Account as of the Participant's date of Termination or Special Deferral payment date, as the case may be. Payment of Accounts shall commence or be made in the month following the month in which the Participant's Termination or Special Deferral payment date occurs; provided, however, if the Management Committee determines that all or part of a payment to be made to a Participant pursuant to this Section 4.8 would be nondeductible by the Company or a subsidiary for Federal tax purposes due to the limitations of Section 162(m) of the Internal Revenue Code, so much of the payment, if any, that would be deductible in the year of Termination (or Special Deferral payment date) shall be paid to the Participant immediately following his or her Termination (or Special Deferral payment date) and, unless the Management Committee, in its sole discretion, directs otherwise, the balance of the Account shall be paid to the Participant (i) with respect to a Termination, not later than the end of the third month of the next following year and (ii) with respect to a Special Deferral payment date, in the first year in which the Management Committee, in its sole discretion, determines either such payment would be deductible or to forego such deduction, in each case such delayed payment being based on the value of the Account at the time of such actual payment. Notwithstanding anything in the Plan to the contrary however, each Participant who has an Account under the Plan on October 1, 1994 shall be given a one-time irrevocable election to change, within the distribution options specified above, the manner in which one or more of such Accounts is to be paid on his or her Termination; provided, however, no such distribution election change shall be effective with respect to any Termination (or Special Deferral payment date) -9- 12 occurring prior to January 1, 1995, unless such Termination is due to the Participant's death, Permanent Disability occurring after October 1, 1994, or involuntary termination by the Company or a subsidiary (whether a termination is involuntary shall be determined by the Committee). Such distribution election change shall be in such form as established by the Management Committee and must be made prior to October 1, 1994. Further, if the Management Committee determines at any time that Participants may be given the ability to change their election as to the form of distribution of their Account(s) without causing the loss of any exempt treatment to "insiders" for securities laws purposes, the Management Committee may amend the Plan to provide for such election changes as it deems appropriate. 4.9 Acceleration of Payments. Notwithstanding a Participant's election to the contrary, the Management Committee, in its sole discretion, may accelerate the payment of all or part of the unpaid balance of a Participant's Account(s) in the event of the Participant's Termination, or upon its determination that the Participant (or his or her Beneficiary in the case of the Participant's death) has incurred a "severe financial hardship" resulting from a sudden and unexpected illness or accident of such person or of a dependent, a loss of such person's property due to casualty, or other similar extraordinary and unforeseeable circumstances arising as a result of events beyond the control of such person. The Management Committee in making its determination of severe financial hardship may consider such factors and require such information as it deems appropriate, but, in any case, payment may not be made to the extent that such hardship is or may be relieved (i) through reimbursement or compensation by insurance or otherwise or (ii) by liquidation of such person's assets, to the extent liquidation of such assets will not itself cause severe financial hardship. However, notwithstanding the foregoing, the Management Committee shall not accelerate the payment of any Common Stock -10- 13 Account maintained for a Participant if such acceleration would cause the loss on any exempt treatment under the Plan for "insiders" for securities laws purposes. 4.10 Payment of Burlington Northern Inc. Deferred Base Salary. Base Salary that was deferred by a Participant under the Burlington Northern Inc. Deferred Compensation Plan, together with interest accrued thereon, shall be paid by the Company in accordance with the terms of this Plan and shall be in lieu of payment by Burlington Northern Inc. SECTION 5 GENERAL PROVISIONS 5.1 Unfunded Obligation. The amounts to be paid to Participants pursuant to this Plan are unfunded obligations of the Company. The Company is not required to segregate any monies from its general funds, to create any trusts, or to make any special deposits with respect to this obligation. Title to and beneficial ownership of any investments, including trust investments, which the Company may make to fulfill this obligation shall at all times remain in the Company. Any investments and the creation or maintenance of any trust or notional accounts shall not create or constitute a trust or a fiduciary relationship between the Management Committee or the Company and a Participant, or otherwise create any vested or beneficial interest in any Participant or his or her Beneficiary or his or her creditors in any assets of the Company whatsoever. The Participants (and Beneficiaries) shall have no claim against the Company for any changes in the value of any Accounts and shall be general unsecured creditors of the Company with respect to any payment due under this Plan. 5.2 Incapacity of Participant or Beneficiary. If the Mangement Committee finds that any Participant or Beneficiary to whom a payment is payable under the Plan is unable to care for his or her affairs because of illness or accident or is under a legal disability, any payment due (unless a prior claim therefore shall have -11- 14 been made by a duly appointed legal representative) at the discretion of the Management Committee, may be paid to the spouse, child, parent or brother or sister of such Participant or Beneficiary or to any person whom the Management Committee has determined has incurred expense for such Participant or Beneficiary. Any such payment shall be a complete discharge of the obligations of the Company under the provisions of the Plan. 5.3 Nonassignment. The right of a Participant or Beneficiary to the payment of any amounts under the Plan may not be assigned, transferred, pledged or encumbered in any manner nor shall such right or other interests be subject to attachment, garnishment, execution or other legal process. 5.4 No Right to Continued Employment. Nothing in the Plan shall be construed to confer upon any Participant any right to continued employment with the Employers, nor interfere in any way with the right of an Employer to terminate the employment of such Participant at any time without assigning any reason therefor. 5.5 Withholding Taxes. Appropriate taxes shall be withheld from the Participant's Base Salary with respect to all deferrals made under the Plan and from all payments made to Participants and Beneficiaries pursuant to the Plan. 5.6 Termination and Amendment. The Compensation and Nominating Committee of the Board may from time to time amend, suspend or terminate the Plan, in whole or in part, and if the Plan is suspended or terminated, the Compensation Committee and Nominating Committee may reinstate any or all of its provisions. The Management Committee may also amend the Plan; provided, however, it may not suspend or terminate the Plan, or substantially increase the obligations of the Company under the Plan (provided, however, the addition of new notional subaccounts for investments shall not be deemed an increase in the obligations of the Company), or expand the classification of employees who are eligible to participate in the Plan. No amendment, suspension or termination of the Plan may impair the -12- 15 right of a Participant or his or her Beneficiary to receive the benefit accrued hereunder prior to the effective date of such amendment, suspension or termination. 5.7 Compliance with Securities Laws. It is the intention of the Company that, so long as any of the Company's equity securities are registered pursuant to Section 12(b) or 12(g) of the Securities Exchange Act of 1934, as amended (the "Exchange Act"), this Plan shall be construed to meet the requirements for exemption from Section 16 of the Exchange Act and, if any Plan provision is later found to be contrary to meeting the requirements for such exemption, that provision shall be deemed null and void. Notwithstanding anything in the Plan to the contrary, the Compensation and Nominating Committee, in its absolute discretion, may bifurcate the Plan so as to restrict, limit or condition the use of any provision of the Plan to Participants who are officers and directors subject to Section 16 of the Exchange Act without so restricting, limiting or conditioning the Plan with respect to other Participants. 5.8 Applicable Law. Except to the extent preempted by applicable federal law, the Plan shall be construed and governed in accordance with the laws of the State of Texas. -13-
