 EXECUTIVE SUPPLEMENTAL RETIREMENT INCOME PLAN 
  
 (2004 RESTATEMENT) 
  
 PURPOSE 
  
 This Executive Supplemental Retirement Income Plan (“Plan”) was established effective January 1, 1981, and was later amended, to promote the best interests of the Company by enabling the Company (a) to
attract to its key management positions persons of outstanding ability, and (b) to retain in its employ those persons of outstanding competence who occupy key executive positions and who in the past contributed and who continue in the future to
contribute materially to the success of the business by their ability, ingenuity and industry. Participation in the Plan is limited to a select group of management and highly compensated employees. Effective September 1, 2004, participation is
limited to Participants in the Plan as of September 1, 2004, and no new Participants will be added to the Plan after September 1, 2004. 
  
 ARTICLE I. DEFINITIONS

 1 

 1.05-1 Total Compensation means the sum of (a) plus (b), subject to (c) and to adjustment under
(d) if applicable: 
  
 (a) The annual salary
approved by the Board of Directors and paid by the Company to take effect starting March 1 of the compensation year. 
  
 (b) The award for prior performance approved by the Board of Directors by such March 1 date; provided, however, that if a Participant
terminates employment during the 61 day period immediately preceding March 1, and if the sum of the prior March 1 salary plus the post retirement performance award is greater than the total compensation using the prior March 1 salary and prior March
1 performance award, final average compensation shall be recalculated for the first ten (10) years combining March 1 salary plus the performance award twelve (12) months later for each of the ten (10) years, and used if the resulting final average
compensation is higher. 
  
 (c) Amounts under
(a) or (b) are not reduced by pre-tax elective deferrals under the Company’s Executive Deferred Compensation Plan (effective January 1, 1987) or the Retirement K Savings Plan.

 2.01 Normal Retirement Supplemental Income. Upon retirement at or after the Normal Retirement Date after becoming vested under 2.05, a retired Participant shall receive during the Participant’s lifetime,
subject to 2.07, monthly supplemental retirement payments determined under 2.01-1 through 2.01-5: 
  
 2.01-1 Determining ESRIP Benefit Amount. The amount to be paid at the Normal Retirement Date under this Plan shall be determined by a three step
process under the following (a), (b) and (c): 
  
 (a) Determine Target Benefit. The sum of the Participant’s accrued target percentage credits under 2.01-2 is multiplied by Final Annual Compensation. 
  
 (b) Determine Offset Amount. The amount to be paid at Normal Retirement Date from three other sources
of retirement or deferred compensation benefits shall be determined under 2.01-3. 
  
 (c) Determine Net Benefit. If the target percentage amount under (a) exceeds the total payments from the other three sources under

 3 

 2.01-2 Accrued Target Percentage. Participant’s accrued target percentage shall be the sum
of the accruals at the rate specified below in (a) for each Year of Participation (defined below in (b)) credited under this Plan. 
  
 (a) Yearly Accrual Percentage Schedule: 
  

(1) Years 1-15. The yearly target percentage accrual for all Participants actively employed on and after September 24, 1998,
shall be: 
  

					
	 Years of Participation

	 	 Accrued Target Percentage for
 Each Year of Participation

	 	 Maximum Total Target
 Percentage

	 Years 1 through 15

	 Years of Participation

	 	 Accrued Target Percentage for
 Each Year of Participation

	 	 Maximum Total Target
 Percentage

	 Years 16 through 25
	 	0.50% per Year	 	 70% (15 Years times 4.33%
 plus 10 Years times 0.50%)

  
 Only Participants
named in the 1998 ESRIP Appendix are eligible for additional accruals for Years of Participation after the 15th Year
of Participation. 
  
 (b) Year of
Participation means the sum of (1), (2) and (3): 
  
 (1) Each consecutive twelve (12) month period of Company service measured by each anniversary of the date of first becoming a Participant under this Plan. 
  
 (2) Any additional Years of Participation awarded to a Participant by the Committee in the exercise of its
discretion. 
  
 (3) All years of service credit
earned for Company service and awarded by the Committee for each of the Participants in the Plan on September 1, 2004, as set forth in the attached 2004 ESRIP Appendix. 
  
 2.01-3 Payments From Other Sources. The total annual payments from the three sources listed below in (a), (b) and
(c) shall be determined, all calculated as a single life annuity starting at Participant’s Normal Retirement Date. 
  
 (a) the Company’s Retirement Plan. 
  

 4 

 (b) Social Security (as determined under 2.01-4(b)(2)). 
  
 (c) Supplemental Retirement payments under the
Company’s Executive Deferred Compensation Plan. 
  
 2.01-4
Benefit Payable Under This Plan. The monthly payment under this Plan shall be the monthly excess of the target benefit amount under 2.01-2 over the total monthly payments under 2.01-3, determined under the formula (a) minus (b), with (c)
acting as a minimum benefit: 
  
 (a) The gross
monthly benefit shall be one-twelfth (1/12) times Final Annual Compensation times the accrued target percentage determined under 2.01-2 above; 
  
 MINUS 
  
 (b) The sum of (1) plus (2) plus (3): 
  
 (1) One-twelfth (1/12) of the Participant’s normal retirement allowance under the Retirement Plan; 
  
 PLUS 
  
 (2) One-twelfth (1/12) of the Participant’s annual primary Social Security benefit determined in the
same manner and based on the same earnings as are used to compute the actual Social Security benefit (including, if appropriate, all compensation deferred by the executive under any plan as though it had been “paid” to or
“received” by the executive in the year when the deferral was made); 
  
 PLUS 
  
 (3)
One-twelfth (1/12) of the Participant’s annual supplemental retirement benefit under the Executive Deferred Compensation Plan determined as a supplement to the normal annual retirement allowance under 2.01-4(b)(1). 
  
 (c) For each of the nine (9) Participants named in the
attached 1998 ESRIP Appendix, the payment amount accrued for such Participant as of December 31, 1998, shall be the amount determined under this section 2.01-4 or, if greater, the amount determined under the ESRIP in effect on January 1, 1998,
without any change by ESRIP Amendment 1998-1. 
  
 2.01-5
Deferred Retirement. Payment shall be deferred to actual retirement if the Participant works for the Company after the Participant’s Normal Retirement Date. The supplemental benefit shall be based on Final Annual Compensation at the date
of actual retirement. 
  

 5 

 2.02 Early Retirement Supplemental Income. Upon retirement at or after age fifty-five (55) with at
least ten (10) years of vesting service under 1.11(b), a retired Participant shall receive during the Participant’s lifetime, subject to 2.07, the reduced monthly supplemental retirement payments determined as follows: 
  
 2.02-1 First, the gross annual retirement benefit at the Participant’s
Normal Retirement Date shall be determined under 2.01-2 using the Participant’s Final Annual Compensation and Service under 1.11(a) at the time employment by the Company ends. 
  
 2.02-2 Second, the monthly supplemental payment under this Plan starting at the Normal Retirement Date shall be determined
under the formula in 2.01-4 using the Participant’s early annual retirement allowance (under Retirement Plan 7.02) payable at his Normal Retirement Date, projected annual primary Social Security benefit under the Retirement Plan, and annual
retirement benefits payable under the Executive Deferred Compensation Plan determined as a supplement to such payment under the Retirement Plan. 
  
 2.02-3 Third, if supplemental payments start before the Participant’s Normal Retirement Date, to achieve the necessary reduction of the target
benefit under 2.01 and 2.02-1, the monthly amount under 2.02-2 shall be reduced by one-half of one percent (0.50%) per month for each month that the benefits begin before the Participant’s 62nd birthday, as illustrated in the following table:

  
 Percentage of ESRIP Normal Retirement Benefit for Benefits
Beginning at Specified Age* 
  

			
		
	 Retirement Age

	 	 Percentage

	 55
	 	58%
	 56
	 	64%
	 57
	 	70%
	 58
	 	76%
	59	 	82%
	60	 	88%
	61	 	94%
	62-64	 	100%

	*	This table shows the percentage reduction based on years. The percentage reduction will be further adjusted for each additional month by which the retirement age precedes the
retirement age specified in the table. 

  
 2.03
Disability Retirement Supplemental Income. Upon total and permanent disability after at least fifteen (15) years of service which qualifies for disability retirement benefits under the Retirement Plan, a retired disabled Participant shall
receive monthly supplemental retirement payments determined as follows: 
  
 2.03-1 First, the total annual retirement pay at normal retirement date shall be determined under 2.01-1 using the Participant’s Final Annual Compensation and Service under 1.11(a) at date of disability.

  

 6 

 2.03-2 Second, the monthly supplemental payment under this Plan starting at the Normal Retirement Date
shall be determined under 2.01-4 using the Participant’s disability annual retirement allowance and projected primary Social Security benefit under the Retirement Plan, and that monthly supplemental amount shall be further reduced by
subtracting the monthly value of any disability benefits payable after the Participant’s 65th birthday under any other Company sponsored disability income plan or under any workers’ compensation law. 
  
 2.03-3 Third, if supplemental payments start before the Participant’s
normal retirement date, the monthly amount under 2.03-2 shall be reduced to the same percentage applicable to a disability retirement benefit under the Retirement Plan starting on the same date, and that monthly supplemental amount shall be further
reduced by subtracting the monthly value of any payments received by the Participant to the Participant’s 65th birthday under any other Company sponsored disability income plan or under any workers’ compensation law. 
  
 2.04 Death Benefits. A death benefit shall be paid if an eligible
Participant dies during employment or before the first one hundred twenty (120) monthly payments have been made under this Plan on account of such Participant, as follows: 
  
 2.04-1 Entitlement and Amount. 
  
 (a) Preretirement Elective Spousal Annuity. For any married Participant who (i) is fifty-five (55) or
older, (ii) has completed at least ten (10) years of service credited for vesting under 1.11(b), and (iii) so elects in writing within ninety (90) days after September 21, 1995, or within ninety (90) days after becoming vested under 2.05, upon the
death of such Participant before any post-retirement form of payment under Article III takes effect, the Participant’s lawful spouse on the date of death shall receive as an annuity for life the actuarial equivalent value (as determined by the
Plan’s actuary) of the surviving spouse’s annuity payable under the full (100 percent) joint and survivor annuity form provided under 3.01-3. Any pre-retirement election of this death benefit shall supersede the regular death benefit under
2.04-1(b) and shall continue until the earlier of (iv) or (v): 
  
 (iv) the Participant’s death before retirement without a spouse (e.g., prior death or divorce of spouse), in which case 2.04-1(b) shall apply; 
  
 (v) the Participant lives until retirement (with or without a spouse), in which case the Participant shall
be entitled to elect to receive any form of post-retirement benefit provided under Article III. 
  
 If no election of this 2.04-1(a) benefit form is made or in effect at the Participant’s death, the only death benefit shall be the benefit under
2.04-1(b) or (c), as applicable. 
  
 (b)
Regular Death Benefit. For regular death benefit payments determined under 2.01, 2.02, 2.03 or 2.05, as applicable, where no election has been made under 2.04-1(a), the death of the Participant must occur after the Participant has, during
active employment of at least ten (10) years of service credited for vesting under 1.11(b), 
  

 7 

 satisfied the age and service requirements to receive normal, early or disability retirement payments
under this Plan (whether the Participant was working or retired at date of death) and prior to the 120th monthly payment. The regular death benefit guarantees that a total of 120 monthly payments of the applicable supplemental payment under this
Plan shall be made to Participant and, if applicable, Participant’s surviving designated beneficiary. Under no circumstances shall any supplemental payment under this (b) be made after the later of the 120th monthly payment or the
Participant’s death. 
  
 (c) Special
Preretirement Death Benefit. For special death benefit payments where 2.04-1(a) and (b) do not apply, the death of the Participant can occur at any age while the Participant remains actively employed by the Company on or after September 24,
1998. The Participant’s accrued benefit under 2.01 at date of death shall be 100% vested and nonforfeitable, and shall be paid under (1) or (2): 
  
 (1) Surviving Spouse Annuity. If Participant is survived by a spouse, such spouse shall receive a fifty percent (50%) survivorship
annuity determined under 3.01-2 as though the Participant had retired on the day before dying. 
  
 (2) Unmarried Participant. If Participant is not married at date of death, Participant’s survivor under 2.04-2 shall receive
one hundred twenty (120) monthly payments equal to 1/12th of twenty-five percent (25%) (or 2.08333%) of the Participant’s Final Annual Compensation determined at date of death. 
  
 2.04-2 Recipient of Nonannuity Benefits. The recipient of death benefits paid under the 120 month guarantee of
2.04-1(b) or (c) shall be Participant’s Surviving Beneficiary or estate, as determined under the following (a), (b) or (c): 
  
 (a) On the death of the Participant before the 120th monthly payment, Participant’s Surviving Beneficiary(ies) shall receive the
balance of the one hundred twenty (120) payments, in monthly or annual payments or in a single Lump Sum payment, as determined by the Committee in its discretion. 
  
 (b) If no designated beneficiary survives the Participant, the unpaid balance of the one hundred twenty
(120) payments shall be paid in a single Lump Sum to the Participant’s estate. 
  
 (c) If the last Surviving Beneficiary dies before the last of the one hundred twenty (120) payments, the unpaid balance shall be paid in a
single Lump Sum to the estate of such last survivor. 
  
 2.04-3
Other Death Benefits. The supplemental death benefit under this Plan shall be in addition to any death benefit provided by any other Company sponsored plan or insurance program. 
  

 8 

 2.05 Vested Benefits. Subject to 2.07, a Participant shall be entitled to receive a specified
percentage of the benefits payable under this Plan based on benefit accruals under 2.01 and Service under 1.11(b), according to the following vesting schedule: 
  

			
	 Completed Years of Vesting Service

	 	 Vested Percentage

	 Years 1-4

	     Year 8
	 	80%
	     Year 9
	 	90%
	 Year 10 and above
	 	100%

  
 2.05-1 Vesting
Service Credit. One year of vesting service is awarded for each period of 12 consecutive months of employment with the Company, with the first such period beginning on the Participant’s employment commencement date and subsequent periods
beginning on each anniversary of the Participant’s employment commencement date. 
  
 2.05-2 Payment of Vested Benefit. A fully or partially vested Participant who is not entitled to early or disability retirement benefits under 2.02 or 2.03 shall be entitled to begin receiving payment of the
vested benefit under the following (a) or (b): 
  
 (a) Termination Before Age 55. If the Participant’s employment terminates before age 55, payment can begin at or after age 55, but if payment starts before age 65, the vested benefit payable under 2.01 will be reduced to reflect
commencement before age 65 under the following table: 
  
 Percentage of ESRIP Normal Retirement Benefit for Benefits Beginning at Specified Age

 (b)
Termination Age 55 or Older. If the Participant’s employment terminates at or after age 55, the vested benefit payable under 2.01 will be reduced using the same reduction percentages applicable to early retirement benefits under 2.02.

  
 2.05-3 Committee Discretion. For any specified
Participant, the Committee may, in its discretion, grant additional vesting service credit, waive the minimum service requirement, reduce the early retirement reduction percentage for payments starting before age 65, or make any appropriate
adjustment of the benefit amount or time of payment under this Plan. 
  

 9 

 2.06 Post-Retirement Change in Retirement Plan Benefits. 
  
 2.06-1 Change in Benefit Formula. If, after supplemental payments
start under this Plan, the benefit payable to a retired Participant is increased under the Retirement Plan by a change in the Retirement Plan benefit formula or its components, the supplemental payment under this Plan shall be reduced to reflect
such increase, effective for and after the first month when such increase is paid. The supplemental benefit shall be recalculated under the benefit formula (2.01, 2.02, 2.03, 2.04 or 2.05) applicable to the retiree by substituting such increased
Retirement Plan benefit in the formula, with all other components of the formula to remain unchanged. 
  
 2.06-2 COLA Supplement. Any post-retirement increase to the Retirement Plan benefit that is not the result of a change of the Retirement Plan
benefit formula or its components (such as a cost of living adjustment for retirees) shall not trigger a recalculation of benefits under 2.06-1 of this Plan. 
  
 2.07 Forfeiture or Suspension of Benefits. Notwithstanding any other provision of this Plan to the contrary, Plan benefits shall be forfeited or
suspended as follows: 
  
 2.07-1 Discharge for Cause. No
supplemental benefits shall be paid if the Participant is discharged from the Company for cause involving illegal or fraudulent acts or conduct detrimental to the interests of the Company. 
  
 2.07-2 Suicide. No supplemental benefits shall be paid if the
Participant commits suicide, while sane or insane, within one (1) year from the date he is enrolled under the Plan. 
  
 2.07-3 Suspended Payment. Supplemental benefit payments shall be suspended during any period of reemployment by the Company or other period when
payments under the Retirement Plan are suspended. If a rehired retiree elects to stop receiving Retirement Plan payments during reemployment under Retirement Plan 6.11, upon later re-retirement the supplemental benefits under this Plan will be
recalculated to take into account any applicable change under Plan 2.01-2.06. 
  
 2.07-4 Agreement Not to Compete. Supplemental benefits shall be withheld pending receipt by the Company of Participant’s written agreement not to compete with the Company or its subsidiaries during the
period of supplemental payments, and shall be suspended or forfeited, as the Committee shall decide, for any breach of such agreement not to compete. 
  

 10 

 2.08 1995 Special Benefit Increase. For all retirees and beneficiaries entitled to receive
benefits on January 1, 1995, based on a retirement date which occurred on or before January 1, 1985, the monthly amount payable on and after January 1, 1995, shall be determined as follows: 
  
 2.08-1 The sum of the benefit amounts payable on December 1, 1994, under
this Plan and the Retirement Plan, multiplied by one hundred five percent (105%); 
  
 2.08-2 Less the benefit amount payable under the Retirement Plan on January 1, 1995, including the amount of the 1995 special benefit increase provided under the Retirement Plan. 
  
 ARTICLE III. PAYMENT OF BENEFITS 
  
 3.01 Form of Payment. Payments to a Participant shall be made monthly
in one of the forms under 3.01-1, 3.01-2 or 3.01-3: 
  
 3.01-1
Life Annuity With One Hundred Twenty (120) Guaranteed Payments. Unless the Participant makes a different election (or is deemed to have made an election for the 50% or 100% Joint and Survivor Annuity under 3.01-2 and 3.01-3), the
Participant’s benefit shall be paid as equal monthly payments for the Participant’s lifetime. If the Participant dies before receiving one hundred twenty (120) monthly payments, the balance of the one hundred twenty (120) payments shall be
made monthly to the beneficiary designated by the Participant, unless the Committee decides to pay an annual benefit or a single Lump Sum to the beneficiary. 
  
 3.01-2 Half (50%) Joint and Survivor Annuity. If the Participant elects the half (50%) joint and survivor annuity form (with or without the
“pop-up” feature) under the Retirement Plan, the Participant shall be deemed to elect to receive payment in the form of a half (50%) joint and survivor annuity under this Plan. The 50% joint and survivor annuity shall be the actuarial
equivalent (as determined by the Plan’s actuary) of the benefit under 3.01-1 and shall pay a reduced amount to the Participant for his life and, if the Participant’s designated joint annuitant survives the Participant’s death, fifty
percent (50%) of the reduced amount will be paid to the joint annuitant for the life of the joint annuitant. The monthly Plan benefit shall be recalculated as a single life annuity following the death of Participant’s joint annuitant if the
“pop-up” annuity is in effect under the Retirement Plan. 
  
 3.01-3 Full (100%) Joint and Survivor Annuity. If the Participant elects to receive the full (100%) joint and survivor annuity form (with or without the “pop-up” feature) under the Retirement Plan, the Participant shall be
deemed to elect to receive payment in the form of a full (100%) joint and survivor annuity under this Plan. The 100% joint and survivor annuity shall be the actuarial equivalent (as determined by the Plan’s actuary) of the benefit under 3.01-1
and shall pay a reduced amount to the Participant for his life and, if the designated joint annuitant survives the Participant’s death, the same amount will be paid to joint annuitant for the life of the joint annuitant. The monthly Plan
benefit shall be recalculated as a single life annuity following the death of Participant’s joint annuitant if the “pop-up” annuity is in effect under the Retirement Plan. 
  

 11 

 3.02 Source. The commitment of the Company to pay supplemental retirement benefits under this Plan
is an unsecured promise of the Company to make the payments. There is no asset or trust fund set aside for payment of benefits hereunder, except to the extent held under the Company’s Umbrella Trust, which is subject to the claims of the
Company’s creditors under conditions specified therein. 
  
 3.03 Key Man Insurance. The Company shall purchase and own such key man life insurance as it chooses on the life of any Participant. No Participant, nor his beneficiaries, heirs, assigns, personal representative or estate, shall have
any right to or interest in any such policy or the proceeds payable thereunder on his death. On death of the Participant, the proceeds shall be paid to the Company. 
  
 ARTICLE IV. ADMINISTRATION 
  
 4.01 Committee Discretion. The Committee shall have full power and authority to interpret, construe and administer
this Plan, to adopt appropriate procedures, and to make all decisions necessary or proper to carry out the terms of the Plan. The Committee’s interpretation and construction hereof, and actions hereunder, including any determination of benefit
amount or designation of the person to receive supplemental payments, shall be binding and conclusive on all persons for all purposes. The timetable and procedure for notice of denial of benefit claims and for hearing on review of such denial shall
be as set forth in Article XII of the Retirement Plan, and the Committee shall make such final review and decision. The Company’s corporate secretary shall act as the Committee’s agent in administering this Plan. Neither the Company, nor
its officers, employees, directors or Committee, nor any member thereof, shall be liable to any person for any action taken or omitted in connection with the interpretation and administration of this Plan. 
  
 4.02 Company Right to Amend or Terminate. The Company, by action of
the Board of Directors, reserves the exclusive right to amend, modify, or terminate this Plan in whole or in part without notice to any Participant. Any such termination, modification or amendment shall not terminate nor diminish any rights or
benefits accrued by any Participant or surviving beneficiary prior thereto. 
  
 ARTICLE V. GENERAL PROVISIONS 
  
 5.01 No Effect on Employment. This Plan shall not be deemed to give any Participant or other person in the employ of the Company any right to be retained in the employment of the Company, or to interfere with the right of the Company
to terminate any Participant or such other person at any time. The Company is authorized and empowered to treat the Participant or other person without regard to the effect which such treatment might have under the Plan. 
  
 5.02 Legally Binding. The rights, privileges, benefits and obligations
under this Plan are intended to be legal obligations of the Company and binding upon the Company, its successors and assigns. The Company agrees it will not be a party to any merger, consolidation or reorganization, unless and until its obligations

 1998 ESRIP CHANGE IN CONTROL APPENDIX 
 TO 
 NORTHWEST NATURAL GAS COMPANY 
 EXECUTIVE SUPPLEMENTAL RETIREMENT INCOME PLAN 
 (Effective September 24, 1998) 
  
 The benefits of any
actively employed Participant covered under the Company’s Executive Supplemental Retirement Income Plan (ESRIP) who has a Qualified Termination of employment within twenty-four (24) months after a Change in Control shall be vested, determined
and paid under the Plan as modified by the provisions set forth below in 1.05A, 1.11(a), 1.14, 1.15, 2.01-2(a)(4), 2.02A, 2.05A, and 4.02A: 
  
 1. Section 1.05A defining “final annual compensation” replaces Plan § 1.05 for any Participant who has a Qualifying Termination under 1.15:

  
 1.05A “Final Annual Compensation: means:

  
 1.05A-1 The annual salary of the Participant last approved by
the Board of Directors and being paid by the Company at the date of the Qualified Termination; 
  
 1.05A-2 Plus the average annual performance award determined by taking the sum of the awards (if any) paid on the three (3) consecutive March 1 award payment dates, which immediately precede the Qualifying Termination
date, and dividing such sum by three (3); provided, however, that if a participant terminates employment during the 61-day period immediately preceding March 1, and if the sum of the post termination performance award plus the two (2) consecutive
preceding awards is greater than the above determined 3-year total of awards, such greater sum shall be divided by three (3) and used to determine final average compensation; 
  
 1.05A-3 Without reduction under 1.05A-1 or 1.05A-2 for any such amounts which are subject to a payment deferral election
under the Company’s Executive Deferred Compensation Plan (effective January 1, 1987) or Retirement K Savings Plan. 
  
 2. Section 1.11(a) is amended to cross reference new 2.01-2(b)(4): 
  
 (a) Benefit Accrual. Service for benefit accrual under 2.01 means years of actual participation,
including service credited under 1.11(c), after becoming a Participant under this Plan, plus any additional years of benefit accrual credit earned or awarded pursuant to 2.01-2(b)(2), (3), or (4). 
  
 3. Section 1.14 is added to define “Change in
Control,” “Potential Change in Control” and “Person.” 

 1.14 Change in Control; Potential Change in Control; Person. 
  
 1.14-1 Change in Control. For purposes of this Plan, a “Change
in Control” of the Company shall mean the occurrence of any of the events described below in (a), (b) or (c), subject to the limitation described in (d): 
  

(a) The approval by the shareholders of the Company of: 
  
 (1) any consolidation, merger or plan of share exchange involving the Company (a “Merger”) in
which the Company is not the continuing or surviving corporation or pursuant to which shares of Common Stock of the Company (“Company Shares”) would be converted into cash, securities or other property, other than a Merger involving
Company Shares in which the holders of Company Shares immediately prior to the Merger have the same proportionate ownership of common stock of the surviving corporation immediately after the Merger; 
  
 (2) any sale, lease, exchange or other transfer (in one
transaction or a series of related transactions) of all, or substantially all, the assets of the Company; or 
  
 (3) the adoption of any plan or proposal for the liquidation or dissolution of the Company; 
  
 (b) At any time during a period of two (2) consecutive
years, individuals who at the beginning of such period constituted the Board (“Incumbent Directors”) shall cease for any reason to constitute at least a majority thereof; provided, however, that the term “Incumbent Director”
shall also include each new director elected during such two-year period whose nomination or election was approved by two-thirds of the Incumbent Directors then in office; or 
  
 (c) Any Person (as hereinafter defined) shall, as a result of a tender or exchange offer, open market
purchases or privately negotiated purchases from anyone other than the Company, have become the beneficial owner (within the meaning of Rule 13d-3 under the Securities Exchange Act of 1934), directly or indirectly, of securities of the Company
ordinarily having the right to vote for the election of directors (“Voting Securities”) representing twenty percent (20%) or more of the combined voting power of the then outstanding Voting Securities. 
  
 (d) Notwithstanding anything in the foregoing to the
contrary, unless otherwise determined by the Board, no Change in Control shall be deemed to have occurred for purposes of this Plan for any Participant who (1) acquires (other than on the same basis as all other holders of Company Shares) an equity
interest in an entity that acquires the Company in a Change in Control otherwise described above in (a), or (2) is part of a group that constitutes a Person which becomes a beneficial owner of Voting Securities in a transaction that otherwise would
have resulted in a Change in Control described above in (c). 
  

 2 

 1.14-2 Potential Change in Control. For purposes of this Plan, a “potential Change in
Control” of the Company shall be deemed to have occurred if the following (a), (b) or (c) occurs: 
  
 (a) the Company enters into an agreement, the approval of which by the shareholders would result in the occurrence of a Change in Control
of the Company; 
  
 (b) any Person (including the
Company) publicly announces an intention to take or to consider taking actions which, if consummated, would constitute a Change in Control of the Company; or 
  

(c) the Board adopts a resolution to the effect that, for purposes of this Plan, a potential Change in Control of the Company has
occurred. 
  
 1.14-3 Person. For purposes of this Plan, the
term “Person” shall mean and include any individual, corporation, partnership, group, association of other “person,” as such term is used in Section 14(d) of the Securities Exchange Act of 1934 (the “Exchange Act”),
other than the Company or any employee benefit plan(s) sponsored by the Company. 
  
 4. Section 1.15 is added defining the termination of employment that qualifies for increased benefits in connection with a Change in Control: 
  
 1.15 Qualifying Termination means the termination of the employment of any Participant within twenty-four (24) months after a Change in Control
event under 1.14, for a reason other than: 
  
 (a) Participant’s death; 
  
 (b)
termination after Participant’s 62nd birthday; 
  
 (c) disability (under 1.15-1) 
  
 (d) termination by the Company for Cause (under 1.15-2); or 
  
 (e) termination by the Participant without Good Reason
(defined in 1.15-3) based on an event occurring concurrent with or after a Change in Control. 
  
 1.15-1 Disability. Termination by the Company of Participant’s employment based on “Disability” shall mean termination because of absence from duties with the Company on a full-time basis for one
hundred eighty (180) consecutive days as a result of Participant’s incapacity due to physical or mental illness, unless within thirty (30) days after Notice of Termination (as hereinafter defined) is given following such absence Participant
shall have returned to the full-time performance of Company duties. 
  

 3 

 1.15-2 Cause. Termination by the Company of a Participant’s employment for “Cause”
shall mean termination upon: 
  
 (a) the willful
and continued failure of Participant to perform substantially the reasonably assigned duties with the Company consistent with those duties assigned prior to the Change in Control (other than any such failure resulting from incapacity due to physical
or mental illness) after a demand for substantial performance is delivered to Participant by the Chairman of the Board or Chief Executive Officer of the Company which specifically identifies the manner in which such executive believes that
Participant has not substantially performed such duties; or 
  
 (b) the willful engaging by Participant in illegal conduct which is materially and demonstrably injurious to the Company. 
  
 (c) For purposes of 1.15-2, no act, or failure to act, shall be considered “willful” unless done, or omitted to be done, in
knowing bad faith and without reasonable belief that the action or omission was in, or not opposed to, the best interests of the Company. Any act, or failure to act, based upon authority given pursuant to a resolution duly adopted by the Board or
based upon the advice of counsel for the Company shall be conclusively presumed to be done, or omitted to be done, by Participant in good faith and in the best interests of the corporation. Notwithstanding the foregoing, Participant shall not be
deemed to have been terminated for Cause unless and until there shall have been delivered a copy of the resolution duly adopted by the affirmative vote of not less than three-quarters of the entire membership of the Board at a meeting of the Board
called and held for the purpose (after reasonable notice and an opportunity for Participant, together with Participant’s counsel, to be heard before the Board), finding that in the good faith opinion of the Board, Participant was guilty of the
conduct set forth above in (a) or (b), and specifying the particulars thereof in detail. 
  
 1.15-3 Good Reason. Termination of a Participant’s employment for “Good Reason” shall mean termination based on: 
  
 (a) a change in Participant’s status, title, position(s) or responsibilities as an officer of the
Company which, in Participant’s reasonable judgment, does not represent a promotion from Participant’s status, title, position(s) and responsibilities as in effect immediately prior to the Change in Control, or the assignment to
Participant of any duties or responsibilities which, in Participant’s reasonable judgment, are inconsistent with such status, title or position(s), or any removal of Participant from or any failure to reappoint or reelect Participant to such
position(s), except in connection with the termination of Participant’s employment for Cause, Disability or Retirement or as a result of Participant’s death or by Participant other than for Good Reason; 
  
 (b) a reduction by the Company in Participant’s base
salary as in effect immediately prior to the Change in Control; 
  

 4 

 (c) the failure by the Company to continue in effect any Plan (as hereinafter defined) in
which Participant is participating at the time of the Change in Control of the Company (or Plans providing Participant with at least substantially similar benefits) other than as a result of the normal expiration of any such Plan in accordance with
its terms as in effect at the time of the Change in Control, or the taking of any action, or the failure to act, by the Company which would adversely affect Participant’s continued participation in any of such Plans on at least as favorable a
basis to Participant as is the case on the date of the Change in Control or which would materially reduce Participant’s benefits in the future under any of such Plans or deprive Participant of any material benefit enjoyed by Participant at the
time of the Change in Control. For purposes of this 1.15-3(c), “Plan” shall mean any compensation plan such as an incentive, stock option or restricted stock plan or any employee benefit plan such as a thrift, pension, profit sharing,
deferred compensation, medical, disability, accident, life insurance, or relocation plan or policy or any other plan, program or policy of the Company intended to benefit employees. 
  
 (d) the failure by the Company to provide and credit Participant with the number of paid vacation days to
which Participant is then entitled in accordance with the Company’s normal vacation policy as in effect immediately prior to the Change in Control; 
  
 (e) the Company’s requiring Participant to be based anywhere other than where Participant’s office is located immediately prior
to the Change in Control except for required travel on the Company’s business to an extent substantially consistent with the business travel obligations which Participant understood on behalf of the Company prior to the Change in Control;

  
 (f) the failure by the Company to obtain from
any Successor (as hereinafter defined) the assent to Participant’s employment or severance agreement (if any); or 
  
 (g) any purported termination by the Company of Participant’s employment which is not effected pursuant to a Notice of Termination
satisfying the requirements of 1.15-4 ; and for purposes of this Plan, no such purported termination shall be effective. 
  
 1.15-4 Notice of Termination. Any purported termination by the Company or by Participant following a Change in Control shall be communicated by
Written Notice of Termination to the other party. For purposes of this Plan, a “Notice of Termination” shall mean a notice which shall indicate the specific termination provision in this Plan relied upon and shall set forth in reasonable
detail the facts and circumstances claimed to provide a basis for termination of Participant’s employment under the provision so indicated. 
  
 1.15-5 Date of Termination. “Date of Termination” following a Change in Control shall mean (a) if Participant’s employment is to be
terminated for a Disability, thirty (30) days after Notice of Termination is given (provided that Participant shall not have returned to the 
  

 5 

 performance of his duties on a full-time basis during such thirty (30) day period, (b) if Participant’s employment
is to be terminated by the Company for Cause, the date on which a Notice of Termination is given, and (c) if Participant’s employment is to be terminated by Participant or by the Company for any other reason, the date specified in the Notice of
Termination, which shall be a date no earlier than ninety (90) days after the date on which a Notice of Termination is given (provided that if the termination is by Participant for Good Reason, the circumstances giving rise to the Good Reason have
not been fully corrected by the specified date), unless an earlier date has been agreed to by the party receiving the Notice of Termination either in advance of, or after, receiving such Notice of Termination. Notwithstanding anything in the
foregoing to the contrary, if the party receiving the Notice of Termination has not previously agreed to the termination, then within thirty (30) days after any Notice of Termination is given, the party receiving such Notice of Termination may
notify the other party that a dispute exists concerning the termination, in which event the Date of Termination shall be the date set either by mutual written agreement of the parties or by the arbitrators in an arbitration proceeding as provided
under the Company’s executive employment or severance agreements. 
  
 4.
Section 2.01-2(b)(4) is added to increase the years of participation benefit accrual by three (3) years for any Participant who has a Qualifying Termination under 1.15: 
  
 (b) Year of Participation means: 
  
 (1) Each consecutive twelve (12) month period of Company service measured by each anniversary of the date of
first becoming a Participant under this Plan. 
  
 (2) All additional years of participation credit awarded to a Participant by the Committee in the exercise of its discretion. 
  
 (3) All years of service credit earned for Company service and awarded by the Committee for each of the ten (10) Participants in the Plan
on September 1, 1998, as set forth in the attached 1998 ESRIP Appendix. 
  
 (4) Three (3) additional years of participation credit shall be awarded to any Participant who has a Qualifying Termination (defined in 1.15) within twenty-four (24) months after a Change in Control (defined in 1.14)
pursuant to the 1998 ESRIP Change in Control Appendix. 
  
 5. Section 2.02A
shall replace 2.02 regarding eligibility to receive and the award of the early retirement benefits for any Participant who has a Qualifying Termination under 1.15: 
  
 2.02A Early Retirement Supplemental Income. Any Participant who has a Qualifying Termination (defined in 1.15) within
twenty-four (24) months after a Change in Control (defined in 1.14) shall be entitled at or after age fifty-five (55) to receive during Participant’s lifetime the reduced monthly supplemental retirement payments determined as follows:

  
 2.02A-1 First, the total annual retirement pay at normal
retirement date shall be determined under 2.01-2 and -3, using the Participant’s final annual compensation and service at the time employment by the Company ends. 
  

 6 

 2.02A-2 Second, the monthly supplemental payment under this Plan starting at normal retirement date shall
be determined under 2.01-4, using the Participant’s early annual retirement allowance payable at the normal retirement date (under Retirement Plan 7.02-1), projected annual primary Social Security benefit under the Retirement Plan, and annual
retirement benefits under the Executive Deferred Compensation Plan determined as a supplement to such payment under the Retirement Plan. 
  
 2.02A-3 Third, if supplemental payments start before the Participant’s normal retirement date, to achieve the necessary reduction of the target
benefit under 2.01 and 2.02A-1, the monthly amount under 2.02A-2 shall be reduced 0.25 percent (.0025) per month for each month of age during the period starting on the date the first early retirement payment is to be made and ending on
Participant’s 62nd birthday. 
  
 6. Section 2.05A shall replace 2.05 regarding the vested benefits of any Participant who has a Qualifying Termination under 1.15:

  
 2.05A Vested Benefits. Any Participant who has a
Qualifying Termination (defined in 1.15) within twenty-four (24) months after a Change in Control (defined in 1.14) thereupon shall have a 100% vested and nonforfeitable right to receive supplemental payments under this Plan starting as early as age
55 under 2.02A. 
  
 7. Section 4.02A replaces Section 4.02 and shall apply
on and after the date there is a Potential Change in Control (defined in 1.14): 
  
 4.02A Company. The Company, by action of the Board of Directors, reserves the exclusive right to amend, modify, or terminate this Plan in whole or in part without notice to any Participant; provided, however,
that the Change in Control benefits provided by the 1998 ESRIP Change in Control Amendment shall not be diminished or eliminated (but may be increased) on and after the date when the first Potential Change in Control (defined in 1.14-2) shall occur
after September 1, 1998. Any such termination, modification or amendment shall not terminate nor diminish any rights or benefits accrued by any Participant or surviving beneficiary prior thereto. 
  
 8. Section 5.02A replaces Section 5.02 to delete the “change of control”
definition that is replaced by 1.14 and to affirm the change of control provisions in this 1998 Amendment: 
  
 5.02 Legally Binding. The rights, privileges, benefits and obligations under this Plan are intended to be legal obligations of the Company and
binding upon the Company, its successors and assigns. The Company agrees it will not be a party to any merger, consolidation or reorganization, unless and until its obligations hereunder shall be expressly assumed by its successor or successors.
Notwithstanding any of the provisions of the Plan to the contrary, upon a change of control (defined in 1.14), the cessation of the corporate existence of the Company or the failure to continue such existence in full force and effect as a result of
any circumstances or event, each Participant shall be entitled to receive any Plan benefits, as determined in accordance with the terms and conditions of payment set forth in Articles II and III, and, if applicable, the 1998 ESRIP Change in Control
Appendix.

 Exhibit 10.3 
  
 FORM OF RESTRICTED STOCK BONUS AGREEMENT 
  
 This Agreement is entered into as of             , 2004,
between Northwest Natural Gas Company, an Oregon corporation (the “Company”), and              (“Recipient”). 
  
 The Company has awarded a restricted stock bonus to Recipient pursuant to
Section 6 of the Company’s Long Term Incentive Plan (the “Plan”) and Recipient desires to accept the award subject to the terms and conditions of this Agreement. 
  
 NOW, THEREFORE, the parties agree as follows: 
  
 1. Award of Restricted Stock Bonus. Subject to the terms and conditions of this Agreement, the Company hereby grants
to Recipient              shares of Common Stock of the Company (the “Restricted Shares”). The Restricted Shares are subject to forfeiture to the Company as set forth in
Section 3. 
  
 2. Shares Purchased on Open Market; Stock
Certificate. 
  
 2.1 As soon as practicable after execution
of this Agreement by the Company and Recipient, the Company shall pay to a securities broker or other third party an amount equal to the market price of the Restricted Shares, with instructions to purchase the Restricted Shares on the open market in
Recipient’s name and to deliver the certificates in Recipient’s name representing the Restricted Shares to the Company to hold pursuant to Section 2.2. 
  
 2.2 To secure the rights of the Company under Sections 3 and 5, the Company will retain the certificate or certificates
representing the Restricted Shares. Upon any forfeiture of Restricted Shares covered by this Agreement, the Company shall have the right to cancel such Restricted Shares in accordance with this Agreement without any further action by Recipient.
After Restricted Shares have vested and all required withholding has been paid to the Company in connection with such vesting, the Company shall deliver a certificate for the vested Restricted Shares to Recipient (unless Recipient shall have made a
deferral election as provided for in Section 5.3). 
  
 3.
Vesting; Forfeiture Restriction. 
  
 3.1 All of the
Restricted Shares shall initially be unvested. The Restricted Shares shall vest in accordance with the following schedule: 
  
 [VESTING SCHEDULE] 
  
 In addition, all Restricted Shares shall immediately vest if (a) Recipient’s employment by the Company is terminated because of death or physical disability (within
the meaning of Section 22(e)(3) of the Internal Revenue Code of 1986 (the “Code”)), or (b) a Change in Control (as defined below) shall occur. 

 3.2 If Recipient ceases to be employed by the Company for any reason or for no reason, with or without
cause, other than death or physical disability (within the meaning of Section 22(e)(3) of the Code), any unvested Restricted Shares shall be forfeited to the Company. 
  
 3.3 For purposes of this Agreement, a “Change in Control” of the Company shall mean the occurrence of any of the
following events: 
  
 (a) The approval by the shareholders of
the Company of: 
  
 (1) any consolidation, merger or plan of
share exchange involving the Company (a “Merger”) in which the Company is not the continuing or surviving corporation or pursuant to which shares of Common Stock of the Company (“Company Shares”) would be converted into cash,
securities or other property, other than a Merger involving Company Shares in which the holders of Company Shares immediately prior to the Merger have the same proportionate ownership of common stock of the surviving corporation immediately after
the Merger; 
  
 (2) any sale, lease, exchange or other transfer
(in one transaction or a series of related transactions) of all, or substantially all, the assets of the Company; or 
  
 (3) the adoption of any plan or proposal for the liquidation or dissolution of the Company; 
  
 (b) At any time during a period of two consecutive years, individuals who at the beginning of such period constituted the
Company’s Board of Directors (“Incumbent Directors”) shall cease for any reason to constitute at least a majority thereof; provided, however, that the term “Incumbent Director” shall also include each new director elected
during such two-year period whose nomination or election was approved by two-thirds of the Incumbent Directors then in office; or 
  
 (c) Any person (as such term is used in Section 14(d) of the Securities Exchange Act of 1934, other than the Company or any employee benefit plan
sponsored by the Company) shall, as a result of a tender or exchange offer, open market purchases or privately negotiated purchases from anyone other than the Company, have become the beneficial owner (within the meaning of Rule 13d-3 under the
Securities Exchange Act of 1934), directly or indirectly, of securities of the Company ordinarily having the right to vote for the election of directors (“Voting Securities”) representing twenty percent (20%) or more of the combined voting
power of the then outstanding Voting Securities. 
  
 4.
Restriction on Transfer. Recipient shall not sell, assign, pledge, or in any manner transfer unvested Restricted Shares, or any right or interest in unvested Restricted Shares, whether voluntarily or by operation of law, or by gift, bequest
or otherwise. Any sale or transfer, or purported sale or transfer, of unvested Restricted Shares, or any right or interest in unvested Restricted Shares, in violation of this Section 4 shall be null and void.

 5. Tax Withholding; Deferral Election. 
  
 5.1 Except as otherwise provided in Section 5.2 or 5.3, Recipient
acknowledges that, on the date (the “Vesting Date”) any portion of the Restricted Shares vests, the Value (as defined below) on that date of such vested Restricted Shares will be treated as ordinary compensation income for federal and
state income and FICA tax purposes, and that the Company will be required to withhold taxes on this income amount. To satisfy the required withholding amount, Recipient shall surrender to the Company the number of vested Restricted Shares having a
Value equal to the required withholding amount, and the Company shall have the right to cancel such number of vested Restricted Shares without any further action by Recipient before delivering the balance of the vested Restricted Shares to Recipient
in accordance with Section 2.2. For purposes of this Section 5, the “Value” of a Restricted Share shall be equal to the closing market price for Company Common Stock on the last trading day preceding the Vesting Date. Notwithstanding the
foregoing, Recipient may elect not to have Restricted Shares withheld to cover taxes by giving notice to the Company in writing prior to the Vesting Date, in which case no certificates for vested Restricted Shares shall be delivered to Recipient
until Recipient shall have paid to the Company in cash any required tax withholding. 
  
 5.2 If Recipient timely files an election under Section 83(b) of the Code with respect to the Restricted Shares, Recipient acknowledges that the Value of the Restricted Shares as of the date of this Agreement will be
treated as ordinary compensation income for federal and state income and FICA tax purposes, and that the Company will be required to withhold taxes on this income amount. Promptly following Recipient’s filing of a timely election under Section
83(b) of the Code, the Company will notify Recipient of the required withholding amount. Within 10 days of such notice, Recipient shall pay to the Company the required withholding amount in cash or, at the election of Recipient, by surrendering to
the Company for cancellation other fully vested Company Shares valued at the closing market price for Company Common Stock on the last trading day preceding the date of Recipient’s election to surrender such shares. 
  
 5.3 If Recipient makes a valid election to defer receipt of vested Restricted
Shares pursuant to the terms of the Company’s Executive Deferred Compensation Plan (as such plan may be amended to permit such elections), any vested Restricted Shares covered by such election shall be delivered to the trustee of the
Company’s Umbrella TrustTM For Executives
promptly following vesting and withholding of taxes shall be governed by the terms of the Executive Deferred Compensation Plan. 
  
 6. Rights as Shareholder; Dividends. Upon the execution and delivery of this Agreement and the purchase of the Restricted Shares in the market as
provided in Section 2.1, the award of the Restricted Shares shall be completed and, except as limited by this Agreement, Recipient shall be the owner of the Restricted Shares with all rights of a shareholder, including the right to vote the
Restricted Shares and to receive dividends payable with respect to the Restricted Shares. Until the Restricted Shares become vested, the Restricted Shares will not be treated as issued shares for tax purposes and dividends paid to Recipient with
respect to unvested Restricted Shares will be treated for federal and state income and FICA tax purposes as ordinary compensation income subject to applicable withholding. 
  

 3 

 7. Additional Company Shares. If, prior to vesting of Restricted Shares, the outstanding Common
Stock is increased as a result of a stock dividend or stock split, the restrictions and other provisions of this Agreement shall apply to any such additional shares of Common Stock which are issued in respect of the Restricted Shares to the same
extent as such restrictions and other provisions apply to the Restricted Shares. 
  
 8. Restrictive Legends. Stock certificates for shares granted under this Agreement may bear the following legends: 
  
 The shares represented by this certificate are subject to a Restricted Stock Bonus Agreement between the registered owner and Northwest Natural Gas
Company which restricts the transferability of the shares. A copy of the agreement is on file with the Secretary of Northwest Natural Gas Company. 
  
 9. No Right to Employment. Nothing contained in this Agreement shall confer upon Recipient any right to be employed by the Company or to continue
to provide services to the Company or to interfere in any way with the right of the Company to terminate Recipient’s services at any time for any reason, with or without cause. 
  
 10. Miscellaneous. 
  
 10.1 Entire Agreement; Amendment. This Agreement constitutes the entire agreement of the parties with regard to the subjects hereof and may be
amended only by written agreement between the Company and Recipient. 
  
 10.2 Notices. Any notice required or permitted under this Agreement shall be in writing and shall be deemed sufficient when delivered personally to the party to whom it is addressed or when deposited into the United States Mail as
registered or certified mail, return receipt requested, postage prepaid, addressed to the Company, Attention: Corporate Secretary, at its principal executive offices or to Recipient at the address of Recipient in the Company’s records, or at
such other address as such party may designate by ten (10) days’ advance written notice to the other party. 
  
 10.3 Assignment; Rights and Benefits. Recipient shall not assign this Agreement or any rights hereunder to any other party or parties without the
prior written consent of the Company. The rights and benefits of this Agreement shall inure to the benefit of and be enforceable by the Company’s successors and assigns and, subject to the foregoing restriction on assignment, be binding upon
Recipient’s heirs, executors, administrators, successors and assigns. 
  
 10.4 Further Action. The parties agree to execute such further instruments and to take such further action as may reasonably be necessary to carry out the intent of this Agreement. 
  
 10.5 Applicable Law; Attorneys’ Fees. The terms and conditions of
this Agreement shall be governed by the laws of the State of Oregon. In the event either party institutes litigation hereunder, the prevailing party shall be entitled to reasonable attorneys’ fees to be set by the trial court and, upon any
appeal, the appellate court.
