EXHIBIT 10 ---------- SPECIAL EMPLOYMENT AGREEMENT THIS AGREEMENT is between NORTHWEST NATURAL GAS COMPANY ("Company") and DWAYNE L. FOLEY ("Employee"), and is made on May 11, 1999. RECITALS: Employee has served as a valued employee involved in the management of the Company. The Company President has determined that it is in the best interests of Company that Employee's employment with Company continue on the terms and conditions set forth herein. Employee wishes to continue his employment with Company on the terms set forth below. AGREEMENT: The parties agree as follows: 1. Employment. Company agrees to employ Employee, and Employee ---------- accepts such employment on the terms and conditions set forth in this Agreement. 1.1 Present to March 31, 2000. During the period from the date of ------------------------- this Agreement through March 31, 2000, Employee agrees to devote such time, attention, effort and ability needed to perform any storage or pipeline work, or other work, that the Company shall need, at times and under circumstances that are mutually agreeable to Company and Employee. Company and Employee agree to cooperate to accommodate their respective needs. Employee shall not be required to be present at any Company facility or report to any Company employee, except as separately so agreed. During this period of paid absence where Employee is subject to being called to perform work for the Company, Employee shall receive monthly his current regular monthly salary of $16,041.67, together with all fringe benefits set forth in Appendix A under "Eligibility 4/23/99 - 9/30/00." 1.2 April 1, 2000 to September 30, 2000. During the period April ----------------------------------- 1, 2000 to September 30, 2000, Employee shall not be subject to call to perform work for the Company and shall not receive a monthly salary, but shall receive the following compensation: (a) A minimum bonus of $38,500 payable on or about 3/1/2000. (b) Accrued vacation payable in six monthly installments of $9,650 each starting April 1, 2000, which is one-sixth of the dollar value of Employee's 625 hours of banked and accrued vacation pay as of February 28, 1999. (c) All fringe benefits set forth in Appendix A under "Eligibility 4/23/99 - 9/30/00." (d) A single cash payment on or about October 1, 2000 equal to the dollar value of any hours of paid vacation accrued from March 1, 1999 to September 30, 2000 which have not been used for paid vacation during that time. 1.3 October 1, 2000 and after. Employee's employment under this ------------------------- Agreement shall terminate at midnight on September 30, 2000, and thereafter he shall be eligible to begin receiving retirement benefits under the Company's post-retirement plans. Such retirement shall not prevent the Company from arranging with Employee to perform services for the Company as an independent contractor or employee under mutually agreed terms. Any such service after September 30, 2000, shall be subject to the terms of any retirement plan regarding suspension of plan benefits during reemployment. 2. Retirement Plan and ESRIP. Employee shall be entitled to coverage and ------------------------- credit under Company's Retirement Plan for Non-Bargaining Unit Employees ("Retirement Plan") and Executive Supplemental Retirement Income Plan ("ESRIP") as follows: 2.1 November 1, 1998 to October 31, 1999. Employee shall receive ------------------------------------ service credit under the Retirement Plan of 900 hours of service for the period of service from November 1, 1998 to April 23, 1999; plus two additional months of service credit at 83 hours per month for two months of paid absence from April 23, 1999 to October 31, 1999, resulting in one full Accredited Year of Service ("AYS") of at least 1,000 hours for his Benefit Accrual Year ("BAY") from November 1, 1998 to October 31, 1999. 2.2 November 1, 1999 to September 30, 2000. For the eleven (11) -------------------------------------- month period November 1, 1999 to September 30, 2000, Employee shall receive monthly service credit at 83 hours per month comprised of four months of paid absence credit from November 1, 1999 to February 28, 2000; plus seven months of service credit for booked and accrued vacation; resulting in 11/12ths AYS for BAY starting November 1, 1999. 2.3 October 1, 2000. Employee shall be an active employee and --------------- Plan member during the month of his 55th birthday (September 25, 2000), and shall be entitled to begin Early Retirement and to receive benefit payments if he so elects under the Retirement Plan and ESRIP on October 1, 2000. (a) ESRIP benefit 10/1/00. For early retirement on or --------------------- after October 1, 2000, Employee shall be entitled to receive, as a single life annuity under the ESRIP (i) the 70% target percentage, (ii) times his highest per year average of three (3) consecutive highest years of salary and performance awards during his final ten (10) years of employment (currently $245,567), (iii) resulting in a yearly target benefit starting at age 65 of $171,896.90 (based on (ii)), (iv) reduced by 0.25 percent (.0025) per month for each month of age before age 62 during the period starting on the date the first early retirement payment is to be made and ending on Employee's 62nd birthday (e.g., on 10/1/00, the reduction is 21%), (v) resulting in a yearly single life annuity amount on 10/1/00 of $135,798.55 (.79 times $171,896.90) and (vi) a monthly amount of $11,316.55. If Employee elects to start receiving payments after 10/1/00, the reduction amount will change and result in a larger monthly ESRIP target amount starting on the first payment month (e.g., a 6% reduction to $13,465.26 on 10/1/05, or no reduction of $14,324.74 on or after 10/1/07). The portion of the ESRIP benefit payable monthly by the Company is reduced by the following (vii)-(ix), also determined as a single life annuity starting at the same first date of payment: (vii) the monthly amount payable to Employee under the Retirement Plan, (viii) the monthly supplemental retirement benefit payable to Employee under the Company's Executive Deferred Compensation Plan ("EDCP"), and (ix) the amount which Employee will be entitled to receive as a retirement benefit from Social Security starting at age 65, which amount shall be determined by using the age 65 amount under the Social Security OASDI table in effect for the calendar year which includes the earliest effective date to receive ESRIP payments and without taking into account any offset that might be imposed because of nonretirement earnings by Employee; provided, however, that solely for payments made before Employee's 65th birthday, the Company shall pay to Employee the Social Security amount deducted under this (ix). Employee shall be entitled to elect to receive payment in any of the forms provided under present ESRIP Article III, or in any other form provided in the ESRIP at the time he elects to begin receiving ESRIP benefit payments, and his single life annuity amount shall be reduced for any benefit form providing survivorship benefits after his death using the actuarial equivalent conversion criteria applicable to all ESRIP beneficiaries at the time of Employee's retirement. An illustration of the estimated amount payable under this 2.3(a) based on information and assumptions at the time this Agreement is signed is attached as Appendix B. (b) Other retirement plan benefits. At retirement on or ------------------------------ after October 1, 2000, Employee shall be entitled to receive the benefits he is entitled to receive under the terms of the Company's Retirement Plan, EDCP and Retirement K Savings Plan. 3. Other Benefits. Employee shall receive the following other -------------- benefits: 3.1 Lump Sum Payment. If Employee is married on October 1, 2000, ---------------- Employee then shall receive a single cash payment that is the actuarial equivalent lump sum present value of the lifetime payments that the Company would be expected to make to provide post-retirement medical coverage to such spouse under the Company's retiree medical plan for qualified non-bargaining unit employees and their spouses, assuming that such coverage for the spouse will start when Employee is age 62 (9/25/07) and that the cost of each future year will equal what the Company pays to provide post-retirement benefits to a qualified spouse during 2000. The lump sum will be calculated using an interest rate of 5.25% per annum and the GAM 83 (50/50) mortality table. As a condition precedent to receiving such lump sum, Employee shall sign a document (attached Appendix C) confirming his agreement to the provisions of 7 - 14 below as applied to the period from the date this Agreement is signed to the date such confirmation is signed. 3.2 Outplacement. Company shall pay $20,000.00 to provide ------------ executive outplacement services for Employee by Right, Chapel & Stowell. 3.3 No Severance; Change in Control. In consideration of the ------------------------------- benefits under this Agreement, Employee shall not be entitled to receive benefits under any Company severance pay plan, program or practice; provided, however, that Employee shall be entitled to receive the benefits he is entitled to in the event of a change in control under the Company's executive severance agreement applicable to Employee or under the ESRIP. 4. Withholdings. Payments made to Employee under 1, 2 and 3 shall ------------ be subject to applicable tax withholding and reporting rules. 5. Proprietary Information. In the course of employment with Company, it ----------------------- is anticipated that Employee may acquire knowledge (both orally and in writing) regarding confidential affairs of Company and confidential or proprietary information relating to Company including but not limited to: (a) business plans and strategies; (b) personnel information; (c) matters under litigation or potential litigation; and (d) other proprietary information and trade secrets which are not required to be disclosed by Company to the public.
