================================================================================ EXHIBIT (10k.) NORTHWEST NATURAL GAS COMPANY EXECUTIVE ANNUAL INCENTIVE PLAN As amended effective January 1, 2000 ================================================================================ EXECUTIVE ANNUAL INCENTIVE PLAN This amended Executive Annual Incentive Plan (the "Plan") is executed by Northwest Natural Gas Company, an Oregon corporation (NNG), effective January 1, 1996. I. PURPOSE OF PLAN 1.0 The success of NNG is dependent upon its ability to attract and retain the services of key executives of the highest competence and to provide incentives for superior performance. The purpose of the plan is to advance the interests of NNG and its shareholders through an incentive compensation program that will attract and retain key executives and motivate them to achieve performance goals. II. TYPE OF PLAN 2.0 This Plan is intended to be and shall be administered by NNG as an income tax nonqualified plan primarily for the purpose of providing compensation for a "select group of management or highly compensated employees" within the meaning of Sections 201(2), 301(a)(3), and 401(a)(1) of the Employee Retirement Income Security Act of 1974, as amended. III. PARTICIPATION 3.0 All executive officers of the company and any other highly compensated employees as designated by the Board of Directors are eligible to participate in the Executive Annual Incentive Plan. 3.1 Each calendar year, NNG's Organization and Executive Compensation Committee (the "Committee") shall determine whether NNG's chief executive officer and other eligible officers shall participate in the Plan. Such participating employees shall be referred to as "Participants." EXECUTIVE ANNUAL INCENTIVE PLAN As amended effective January 1, 2000 Page 2 IV. INCENTIVE COMPENSATION 4.0 Each Participant's potential total incentive compensation consists of two components, a corporate performance award and an individual performance award. 4.1 The total incentive compensation award ("Award") consists of: (a) Base salary x Corporate performance rating x Corporate allocation percentage x Target percentage; plus, (b) Base salary x Individual performance rating x Individual allocation percentage x Target percentage. 4.2 There shall be no incentive compensation award under the Plan for any Plan Year in which net income shall be less than dividends payable on the preferred, preference and common stock. V. DEFINITIONS Corporate Allocation Percentage - ------------------------------- 5.0 The corporate allocation percentage reflects the Participant's contribution to corporate performance. The difference between this percentage and 100% is the individual allocation percentage. The ratio will be determined annually by the Committee. EXECUTIVE ANNUAL INCENTIVE PLAN As amended effective January 1, 2000 Page 3 Corporate Performance Matrix - ---------------------------- 5.1 At the beginning of each fiscal year ("Plan Year"), a corporate performance matrix shall be submitted to the Committee for approval. The vertical axis represents the average of the corporate performance goals. The horizontal axis represents the percentage attainment of the earnings plan. 5.1.1 Should unexpected deviations in corporate goals occur in the course of the Plan Year that produce distortions in the application of the matrix, the Committee may adjust the matrix to correct the distortions. Individual Performance Rating - ----------------------------- 5.2 The Participant's individual performance rating is determined by the executive's performance evaluation by his superior officer as approved by the C.E.O. If the Participant's individual rating is less than .5 on a scale of 0 to 1.5, he shall receive no Award. Target Percentage 5.3 The target percentage is the percentage of Base salary determined by the Committee to be appropriate for each Participant. Calculation of the Award - ------------------------ 5.4 The Committee shall calculate the Award for each Participant for a Plan Year no later than two months after the end of the Plan Year. In the event of a change in job position during the year, the Committee may, in its discretion, increase or decrease the amount of a Participant's Award to reflect such change. Right to Receive Award - ---------------------- 5.5 A Participant must continue employment with NNG until the end of the Plan Year in order to be entitled to receive the Participant's Award in accordance with the terms of the Plan. This shall not be a guarantee of employment and such employment may be terminated by either party to the employment relationship at any time and for any reason which does not violate any preexisting law or other agreement, if any, between the parties. If a Participant's employment with NNG or its subsidiaries is terminated prior to the EXECUTIVE ANNUAL INCENTIVE PLAN As amended effective January 1, 2000 Page 4 end of the Plan Year for a reason other than death, disability, or retirement, the Participant shall not be entitled to any payment of an Award for that Plan Year. If a Participant's employment with NNG is terminated prior to the end of the Plan Year due to death, disability, or retirement, the Committee, in its sole discretion, shall determine whether the Participant or the Participant's beneficiary or estate shall be entitled to receive payment of a portion of the Participant's Award for the Plan Year. VI. ADMINISTRATION 6.0 The Plan shall be administered by the Committee. The Committee shall have the exclusive authority and responsibility for all matters in connection with the operation and administration of the Plan. The Committee's powers and duties shall include, but shall not be limited to, the following: (a) Responsibility for the compilation and maintenance of all records necessary in connection with the Plan; (b) Subject to the Board of Directors approval authorizing the payment of all benefits and expenses of the Plan as they become payable under the Plan; and (c) Authority to engage such legal, accounting, and other professional services as it may deem proper. 6.1 Decisions by the Committee shall be final and binding upon all parties affected by the Plan, including the beneficiaries of Participants. 6.2 The Committee may rely on information and recommendations provided by management. The Committee may delegate to management the responsibility for decisions that it may make or actions that it may take under the terms of the Plan, subject to the Committee's reserved right to review such decisions or actions and modify them when necessary or appropriate under the circumstances. The Committee shall not allow any employee to obtain control over decisions or actions that affect that employee's Plan benefits.
