may use the Commitment by borrowing, prepaying the Loans in whole or in part and reborrowing, all in accordance with the terms and conditions hereof.

Bank on or prior to the first day of any month that the Company requests that the Bank make that portion of the Excess Line Commitment available, in increments of $500,000, to the Company during such month; provided, however, that at any time as
there may 

  

 9 

 
exist any outstanding Loans under the Excess Line Commitment, the Company shall be deemed to have given notice requesting availability under the Excess Line
Commitment. 
  
 (c) The Loans may be, to the extent any such Type
is available in accordance with Schedule I hereto, either (i) LIBOR Loans, (ii) Prime Rate Loans, (iii) C/D Rate Loans (iv) Fed Funds Rate Loans, (v) Negotiated Rate Loans or (vi) a combination thereof, provided

the Bank, each continuation thereof, each conversion of all or a portion thereof to another Type, the date and amount of each prepayment of principal thereof, and, in the case of LIBOR Loans, C/D Rate Loans or Negotiated Rate Loans, the length of
each Interest Period and the interest rate with respect thereto, on the schedule annexed to and constituting a part of its Note, and any such recordation shall constitute prima facie evidence of the accuracy of the information so
recorded; provided, however, that the failure of the Bank to make any such recordation or any error in any such recordation shall not affect the obligations of the Company hereunder or under such Note; provided, further,
however, that in the absence of any such recordation, the loan accounts and records of the Bank shall constitute prima facie evidence of the outstanding amount of any Loans and interest accrued thereon. 
  
 2.2 Termination or Reduction of Commitments; Extension of Commitment
Termination Date. (a) The Company shall have the right, upon not less than three Business Days’ notice to the Bank, to terminate the Commitment or, from time to time, reduce the amount of the Commitment, provided that (i) no such
reduction or termination shall be permitted if, after giving effect thereto and to any prepayments of the Loans made on the effective date thereof, the then outstanding principal amount of the Loans would exceed the amount of the Commitment then in
effect and (ii) any termination of the Commitment while LIBOR Loans or C/D Rate Loans are outstanding and any reduction of the aggregate amount of the Commitment that reduces the amount of the Commitment below the principal amount of the LIBOR
Loans or C/D Rate Loans then outstanding may be made only on the last day of the respective Interest Period for such LIBOR Loans or C/D Rate Loans. Termination of the Commitment shall also terminate the obligation of the Bank to make Loans.

 10 

 2.3 Interest Rate Options. The Company shall have the options set forth on Schedule I
hereto from which to choose interest rates payable on amounts outstanding under the Loans, as the Company shall specify in the related Notice of Election (each an “Interest Rate Option”). The Interest Rate Options to be made available by
the Bank at the time of any requests for Loans shall include a LIBOR Loan and at least one and as many as all of the following as are elected on Schedule I: 
  
 (a) Prime Rate Loans. 
  
 A Prime Rate Loan shall bear interest at the per annum rate equal to the Bank’s Prime Rate, fully
floating, and each change in said rate to become effective on the effective date of each change announced by the Bank. Interest shall be computed on the outstanding principal amount on the basis of a 365-day or 366-day year, as applicable, and
actual days elapsed. If at any time there is no Interest Rate Option in effect for an amount outstanding hereunder, the Company shall be deemed to have elected the Prime Rate for such amount. 
  
 (b) C/D Rate Loans. 
  
 A C/D Rate Loan shall bear interest at the Adjusted C/D Rate
plus the applicable Rating Level Margin set forth on Schedule I for each Interest Period. Interest shall be computed on the outstanding principal amount for the actual number of days elapsed from the first day of the applicable Interest
Period to, but not including, the last day thereof, on the basis of a 360-day year. 
  
 (c) LIBOR Loans. 
  
 A LIBOR Loan shall bear interest at the Adjusted LIBOR Rate plus the applicable Rating Level Margin for each Interest Period set forth on
Schedule I . Interest shall be computed on the outstanding principal amount for the actual number of days elapsed from the first day of the applicable Interest Period to, but not including, the last day thereof, on the basis of a 360-day
year. 
  
 (d) Fed Funds Rate Loans.

  
 A Fed Funds Rate Loan shall bear interest at
the Fed Funds Rate, fully floating, plus the applicable Rating Level Margin for each Interest Period set forth on Schedule I. Interest shall be computed on the outstanding principal amount on the basis of a 360-day year, as applicable, and
actual days elapsed. 
  
 (e) Negotiated Rate
Loans. 
  
 The Company may request the Bank
to provide a bid stating the lowest fixed rate at which the Bank would be willing to make a Loan to the Company for the Interest Period, with the Interest Payment Dates and method of interest calculation, and in the amount requested. Such request
for a bid may be made by the Company at any time prior to the proposed Borrowing or conversion of outstanding Loans. Any Loan made at such bid rate shall be a Negotiated Rate Loan. The Bank shall advise Company of its bid rate and the Company may
choose to accept such rate in its sole 

  

 11 

 
discretion by electing a Negotiated Rate Loan in its Notice of Election. Interest on a Negotiated Rate Loan shall be computed on the basis of a 360-day year,
as applicable, and actual days elapsed. 
  
 2.4 Election
Procedures. 
  
 (a) The Company shall give
notice of each proposed Borrowing and/or interest rate election (“Notice of Election”) to the Bank in writing or by telephone, and confirmed as soon as practicable in writing. Such Notice is to be received by the Bank no later than 10:00
a.m., Pacific time, on the proposed date of the Loan and/or commencement date of the Interest Period; except that Notice of Election to borrow or convert to (i) a LIBOR Loan shall be received no later than 10:00 a.m. (Pacific time) three
Business Days prior to the proposed date of the Loan or conversion or, (ii) a C/D Rate Loan shall be received by the Bank no later than two Business Days prior to the proposed date of the Loan or conversion. The Bank shall be entitled to rely
on any Notice of Election given on behalf of the Company by any Responsible Officer or any other person authorized in writing by a Responsible Officer to give such Notice. 
  
 Each Notice of Election shall specify the amount (and how much of said amount is a conversion of an
outstanding Loan) and date of the Loan, Interest Rate Option, and, in the case of a requested C/D Rate Loan, or LIBOR Loan the Interest Period, and in the case of a Negotiated Rate Loan for which a bid is being accepted the Interest Period and the
Interest Payment Date(s). 
  
 (b) Each C/D Rate
Loan, or LIBOR Loan shall be in the principal amount of Five Hundred Thousand and No/100 Dollars ($500,000.00) or an amount greater by multiples of One Hundred Thousand and No/100 Dollars ($100,000.00). In the case of Prime Rate Loans or Negotiated
Rate Loans, the Company may borrow in any principal amount up to the amount of the Commitment Amount. 
  
 (c) On the date of a proposed Loan, the Bank shall transfer to the Company the principal amount of the Loan to such account in such bank
as the Company instructs the Bank in writing. Loans shall be made and repaid in immediately available funds unless the Company and the Bank may otherwise agree in writing in their sole discretion. 
  
 (d) When the Company makes borrowings under the Credit
Agreements, it shall request such Loans equally from each of the Banks that are party to the Credit Agreements; provided, however that in no event shall the Company be required to request a Loan of less than $2 million from any one Bank. For
purposes of clarification, assuming that there are five Banks that are party to the Credit Agreements and that the Company chooses to borrow Loans aggregating $10 million, the Company shall request $2 million from each of the five Banks that are
party to the Credit Agreement. If the Company chooses to borrow an additional $4 million, the Company need only request loans in the amount of $2 million from any two of the five Banks. 
  

 12 

 2.5 Principal and Interest Payments; Prepayments. 
  
 (a) The aggregate unpaid principal amount of all Loans
outstanding under this Agreement, together with unpaid accrued interest thereon, shall be due and payable in full on the Commitment Termination Date. The Company may from time to time prepay any Prime Rate Loan or Fed Funds Rate Loan in whole or in
part without premium or penalty. Borrower may not prepay a Negotiated Rate Loan, C/D Rate Loan or LIBOR Loan prior to the last day of the applicable Interest Period. Interest on each Loan shall be payable in arrears on each Interest Payment Date
with respect thereto. 
  
 (b) All payments shall
be made by the Company to the Bank not later than 12:00 Noon, Pacific time, on the date due, at the office of the Bank designated on Schedule I for such purpose, or such other place as the Bank may designate in writing. 
  
 (c) If any payment of principal or interest falls due on a
day which is not a Business Day, then such due date shall be extended to the next following Business Day, subject to clause (i) of the definition of “Interest Period.” Additional interest shall accrue and be payable for the period of
any such extension. All payments hereunder shall be applied first to interest, then to principal. 
  
 (d) Any overdue principal on any of the Loans, and to the extent permitted by law, overdue interest thereon, shall bear interest, payable
on demand, for each day from the date on which payment was due until the date of payment at a rate per annum equal to the Prime Rate plus 1.5% per annum (computed on the basis of a 360-day year and the actual number of days elapsed).

  
 (e) When the Company makes any payment or
prepayment on the Loans, it shall offer such payment or prepayment on a pro rata basis to each Bank that is a party to the Credit Agreements; provided however that in no event shall the Company be required to make a Loan payment or prepayment to any
one bank for an amount less than $2 million; and provided further that in no event shall the Company, as a result of this Section 2.5, be required to make any payment or prepayment on the Loans that would result in the Company’s obligation
to indemnify one or more Banks under Section 2.11 of this Agreement. 
  
 2.6 Modification to Adjusted LIBOR Rate or Adjusted C/D Rate Calculations. If after the date of this Agreement there is a change in any law, rule or regulation, or in the interpretation or administration
thereof by any Governmental Authority, central bank or comparable agency, or compliance by the Bank with any request or direction (whether or not having the force of law) of any such authority, central bank or comparable agency that subjects the
Bank to additional costs in, or reduces, in the Bank’s opinion, the amount of any payment received or receivable by the Bank under this Agreement or under the Note by reason of obtaining funds in the LIBOR or domestic C/D markets, through
imposition of additional taxes, reserves or any other conditions, then the formulas for calculating the Adjusted LIBOR Rate and Adjusted C/D Rate for LIBOR or C/D Rate Loans shall immediately be modified to reflect and include the impact of such
change whether or not the Bank purchases funds in the applicable LIBOR or domestic C/D markets. The Bank shall provide the Company with a statement detailing any modification of calculation. 
  

 13 

 2.7 Unavailability of Certain Loans. If, with respect to any Interest Period for a C/D Rate Loan
or LIBOR Loan, the Bank determines that deposits in dollars are not being offered in the relevant market for such Interest Period, or that adequate and reasonable means do not exist for ascertaining the applicable rate for a LIBOR Loan or C/D Rate
Loan, then the Bank shall promptly notify the Company thereof by telephone, confirmed in writing, and any request by the Company for such C/D Rate Loan or such LIBOR Loan shall be deemed to be rescinded. In the case of any outstanding C/D Rate Loans
or LIBOR Loans so affected, on the last day of the then current Interest Period for such Loans, Borrower shall either repay the Loans in full or the Loans shall automatically be converted into Prime Rate Loans, or at the Company’s election,
Loans of another available Type. Thereafter, the obligation of the Bank to make C/D Rate Loans or LIBOR Loans, as the case may be, shall be suspended until the Bank revokes the notice to the Company referenced in this subsection 2.7. 
  
 2.8 Changes in Law Rendering Certain Loans Illegal. If after the date
of this Agreement there is a change in any law (including the adoption of any new law), rule or regulation or in the interpretation or administration thereof by any Governmental Authority, central bank or comparable agency that renders it illegal
for the Bank to make or maintain C/D Rate Loans or LIBOR Loans, or makes it illegal for the Bank to fund itself in the applicable LIBOR or C/D markets, then the Bank shall promptly so notify the Company, and upon the effective date of such event,
suspend availability of the LIBOR option or C/D Rate option for the duration of the illegality. If Bank requests, as may be required by the relevant law, rule, regulation, interpretation or administration, the Company shall repay or convert to
another Type any such LIBOR Loan or C/D Rate Loan. 
  
 2.9
Capital Adequacy Adjustment. If, after the date hereof, the adoption or effectiveness of any applicable law, rule or regulation regarding capital adequacy, or any change in any existing law, rule or regulation or any change in the
interpretation or administration thereof by any Governmental Authority, central bank or comparable agency charged with the interpretation or administration thereof, or compliance by the Bank with any request or directive regarding capital adequacy
(whether or not having the force of law) of any such authority, central bank or comparable agency, has or would have the effect of reducing the rate of return on the Bank’s capital or assets as a consequence of the Bank’s Commitment,
Loans, credits or obligations under this Agreement to a level below that which the Bank could have achieved but for such adoption, effectiveness, change or compliance (taking into consideration the Bank’s policies with respect to capital
adequacy), and the Bank demonstrates that the amount of the reduction reasonably attributable to such adoption, effectiveness, change or compliance is material to the Bank, then from time to time, within fifteen (15) days after demand by the
Bank, the Company shall (a) pay to the Bank such additional amount or amounts as will compensate the Bank for such reduction or (b) prepay the outstanding balance hereunder without premium or penalty except as required in subsection 2.11.
In determining such amount(s), the Bank may use any reasonable averaging and attribution methods. 
  
 2.10 Commitment and Upfront Fees. During the term of this Agreement, the Company shall pay to the Bank commitment fees and upfront fees computed at
the rates set forth in Schedule I. The commitment fees and shall be computed for the 

  

 14 

 
actual number of days elapsed on the basis of a 360-day year, as applicable, and shall be due and payable quarterly in arrears on the last day of March,
June, September and December and on the Commitment Termination Date, unless payment terms are otherwise provided on Schedule I. The upfront fees shall be due and payable upon execution of this Agreement. Payment of fees shall be made at the
office of Bank designated by Bank on Schedule I for the purpose of payment. 
  
 2.11 Indemnity for Certain Fees. The Company agrees to indemnify the Bank and to hold the Bank harmless from any loss or expense which such Bank may sustain or incur as a consequence of (a) default by the
Company in payment when due of the principal amount of or interest on any Loan, (b) default by the Company in making a borrowing or conversion after the Company has given a Notice of Election in accordance with subsection 2.4, and/or
(c) the making by the Company of a payment of any LIBOR Loan or C/D Rate Loan on a day which is not the last day of the Interest Period pertaining thereto, including, without limitation, any such loss or expense arising from the reemployment of
funds obtained by it to maintain its Loans hereunder or from fees payable to terminate the deposits from which such funds were obtained, but excluding loss of margin for the period after a prepayment described in clause (c) above and, as to
clauses (a), (b) and (c) of this subsection 2.11, excluding any consequential damages. This covenant shall survive termination of this Agreement and payment of the Note. 
  
 2.12 Use of Proceeds. The proceeds of the Loans shall be used for general corporate purposes of the Company. The
Company will not, nor will it permit any Subsidiary to, use any of the proceeds of the Loans to purchase or carry any “Margin Stock” (as defined in Regulation U of the Board of Governors of the Federal Reserve System, as amended from time
to time). 
  
 2.13 Other Agreements. None of the Credit
Agreements contains any provision, including, without limitation, any financial covenant, which (a) increases or expands material restrictions on the Borrower as compared to those contained herein; (b) provides for options for interest
rates other than those listed on Schedule I; (c) provides for fees or penalty terms other than those described herein; (d) provides for maturity earlier than the maturity hereof; or (e) grants collateral for the obligations of the
Borrower. 
  
 2.14 General Indemnity. The Company agrees to
indemnify Bank and its respective directors, officers, employees and agents (each an “Indemnitee”) against, and to hold each Indemnitee harmless from, any and all losses, claims, damages, liabilities and related expenses, including
reasonable counsel fees, charges and disbursements (but excluding income, franchise and similar taxes), incurred by or asserted against any Indemnitee arising out of, in any way connected with, or as a result of (a) the execution or delivery of
this Agreement or any agreement or instrument contemplated hereby, the performance by the parties hereto of their respective obligations hereunder or the consummation of the transactions contemplated hereby; (b) use of the proceeds of the
Loans; or (c) any claim, litigation, investigation or proceeding relating to any of the foregoing, whether or not any Indemnitee is a party thereto; provided that such indemnity shall not, as to any Indemnitee, be available to the extent that
such losses, claims, damages, liabilities or related expenses are determined by a court of competent jurisdiction by final and nonappealable judgment to have 

  

 15 

 
resulted from the gross negligence or willful misconduct of any Indemnitee. The provisions of this Section 2.14 shall remain operative and in full force
and effect regardless of the expiration of the term of this Agreement, the consummation of the transaction contemplated hereby, the repayment of any of the Loans, the invalidity or unenforceability of any term or provision of this Agreement or any

 22 

 (c) The Company shall default in the observance or performance of any other agreement or covenant
contained in this Agreement, and such default shall continue unremedied for a period of 30 days after written notice thereof shall have been given to the Company by the Bank; provided, however, that no such written notice or cure period shall apply
to default in the observance or performance of the covenants described in Sections 6.1 and 6.2; or 
  
 (d) The Company shall default in any payment of principal of or interest on any Indebtedness for borrowed money under any one of the Credit Agreements; or

  
 (e) The Company shall fail to make any payment in respect of
any Funded Indebtedness (other than the Notes) having singly or in the aggregate an outstanding amount in excess of $15 million when due or within any applicable grace period; 
  
 (f) A final judgment for the payment of money exceeding an aggregate of $15 million shall be rendered or entered against the

an Event of Default specified in clause (i) or (ii) of paragraph (g) above with respect to the Company, automatically the Commitments shall immediately terminate and the Loans hereunder (with accrued interest thereon) and all other
amounts owing under this Agreement and the Note shall immediately become due and payable, and (B) if such event is any other Event of Default, either or both of the following actions may be taken: (i) the Bank may, by notice to the Company
declare the Commitment to be terminated, whereupon the Commitment shall immediately terminate; and (ii) the Bank may, by notice of default to the Company, declare the Loans hereunder (with accrued interest thereon) and all other amounts owing
under this Agreement and the Note to be due and payable whereupon the same shall immediately become due and payable. Except as expressly provided above in this Section, presentment, demand, protest and all other notices of any kind are hereby

 8.2 Waiver; Amendment. 
  
 (a) No delay or omission to exercise any right, power or remedy accruing to the Bank upon any breach or Default by the Company under this Agreement shall impair any such right, power or remedy of the Bank, nor shall
it be construed to be a waiver of any such breach or default, or an acquiescence therein, or of or in any similar breach or Default thereafter occurring; nor shall any waiver of any single breach or default be deemed a waiver of any other breach or
default theretofore or thereafter occurring. Any waiver, permit, consent or approval of any kind or character on the part of the Bank of any breach or Default under this Agreement or any waiver on the part of the Bank of any provision or condition
of this Agreement must be in writing and shall be effective only to the extent in such writing specifically set forth. All remedies, either under this Agreement or by law or otherwise afforded to Bank, shall be cumulative and not alternative.

  
 (b) Neither this Agreement nor any provision
hereof may be amended, waived, discharged or terminated orally, but only by an instrument in writing, signed by the Company and the Bank. 
  
 8.3 Survival. All warranties, representations and covenants made by the Company herein or in any certificate or other instrument delivered by it or
on its behalf under this Agreement shall be considered to have been relied upon by the Bank and shall survive the making of any Loan hereunder and delivery to the Bank of the Note, regardless of any investigation made by the Bank or on its behalf.

other instrument or agreement required or contemplated hereunder, the prevailing party, in addition to all other sums which the other party may be called upon to pay, shall be entitled to recover 

  

 24 

 
such additional sum for the prevailing party’s attorneys’ fees (including the allocated cost of internal counsel), incurred therein, as the trial
court or any appellate court adjudges reasonable in said suit or action. 
  
 8.6 Governing Laws; Jurisdiction. 
  
 (a) This Agreement, the Note, and any other instrument or agreement required or contemplated hereunder, shall be governed by, and construed under, the laws of the State of Oregon without regard to principles of
conflicts of law. Any suit or action in regard to or arising out of the terms or conditions of this Agreement shall be litigated in the state or federal courts situated in the State of Oregon, and the Company and the Bank hereby submit to the
jurisdiction of those courts. 
  
 (b) The Company
and the Bank hereby irrevocably submit to the jurisdiction of any state or federal court sitting in Portland, Oregon, for any action or proceeding relating to this Agreement. The Company waives any objection which it may now or hereafter have to a
laying of venue in any such action or proceeding in any such forums, and also waives any claim that any such forum is an inconvenient forum. The Company and the Bank agree that a final judgment in any such action or proceeding shall be conclusive
and may be enforced in other jurisdictions by suit on the judgment or any other manner provided by law. The Company agrees that it shall not bring suit or action arising out of this Agreement in the courts of any other jurisdiction, and the Bank
agrees that it will not bring suit or action against the Company in any other jurisdiction provided that the Company maintains its corporate headquarters and a substantial business presence in Oregon. 
  
 (c) The Company and the Bank hereby waives, to the fullest
extent permitted by applicable law, any right it may have to a trial by jury in respect of any litigation directly or indirectly arising out of, under or in connection with this Agreement or any related document. The Company and Bank hereto

and the other parties hereto have been induced to enter into this Agreement by, among other things, this mutual waiver. 
  
 8.7 Counterparts. This Agreement may be executed in as many counterparts as may be deemed necessary or convenient, each of which, when so executed,
shall be deemed an original, but all such counterparts shall constitute but one and the same instrument. 
  

 25 

 8.8 Participations. 
  
 (a) Bank may grant participations to one or more banks or other entities in all or any part of any Loan or
Loans owing to the Bank hereunder and also the Note held by the Bank. 
  
 (b) In the event that Bank grants, assigns, or sells any of its interest in this Agreement or the Note, including the sale of a participation herein, such grantee, assignee, purchaser or participant is hereby granted
the right of setoff against any and all property which may come into its possession to the same extent as if it were the Bank; provided that such rights are employed solely to reduce the amount of the Company’s obligations hereunder. The Bank
shall have no liability for any setoff or action taken by any participant without the Bank’s consent. 
  
 8.9 Entire Agreement. This Agreement, together with the Note and the other documents and agreements required hereunder, embodies the entire
agreement and understanding between the Company and the Bank, and supersedes all prior and contemporaneous agreements and understandings of such Persons, verbal or written, relating to the subject matter hereof and thereof. Terms and conditions of

that have executed Credit Agreements.

Document. The Company and the Bank hereby acknowledge receipt of a copy of this Agreement. 
  
 8.11 Interest Rate Limitation. Notwithstanding anything herein to the contrary, if at any time the interest rate applicable to any of the Loans, together with all fees, charges and other amounts which are
treated as interest on such Loan under applicable law (collectively the “Charges”), shall exceed the maximum lawful rate (the “Maximum Rate”) which may be contracted for, charged, taken, received or reserved by the
Bank in accordance with applicable law, the rate of interest payable in respect of such Loan hereunder, together with all Charges payable in respect thereof, shall be limited to the Maximum Rate and, to the extent lawful, the interest and Charges
that would have been payable in respect of such Loan but were not payable as a result of the operation of this section shall be cumulated and the interest and Charges payable to the Bank in respect of other Loans or periods shall be increased (but
not above the Maximum Rate therefore) until such cumulated amount, together with interest thereon at the Federal Funds Rate to the date of repayment, shall have been received by the Bank. 
  
 8.12 USA Patriot Act. The Bank hereby notifies the Company that pursuant to the requirements of the USA Patriot Act
(Title III of Pub. L. 107-56 (signed into law October 26, 2001)) (the “Act”), it is required to obtain, verify and record information that identifies the Company, which information includes the name and address of the Company and

as of                         , between Northwest Natural Gas Company, an Oregon corporation (the “Company”), and
____________ (“Recipient”). 
  
 On
                        , the Organization and Executive Compensation Committee (the “Committee”) of the Company’s
Board of Directors (the “Board”) authorized an objectively-determinable performance-based award (the “TSR Award”) to Recipient pursuant to Section 8 of the Company’s Long Term Incentive Plan (the “Plan”) and a
subjective performance-based award (the “Strategic Award”) to Recipient pursuant to Section 6 of the Plan. Compensation paid pursuant to the TSR Award is intended to qualify as performance-based compensation under Section 162(m)
of the Internal Revenue Code of 1986 (the “Code”), while compensation paid pursuant to the Strategic Award will not so qualify. Recipient desires to accept the awards subject to the terms and conditions of this Agreement. 
  
 NOW, THEREFORE, the parties agree as follows: 
  
 1. Awards. Recipient’s “Target Share Amount” for
purposes of this Agreement is ________ shares. 
  
 1.1 TSR
Award. Subject to the terms and conditions of this Agreement, the Company shall issue or otherwise deliver to the Recipient the number of shares of Common Stock of the Company (the “TSR Performance Shares”) determined under this
Agreement based on (a) the performance of the Company’s Common Stock relative to a peer group of companies during the three-year period from January 1,          to December 31,
         (the “Award Period”) as described in Section 2 and (b) Recipient’s continued employment during the Award Period as described in Section 4. If the Company issues or
otherwise delivers TSR Performance Shares to Recipient, the Company shall also pay to Recipient the amount of cash determined under Section 5 (the “TSR Dividend Equivalent Cash Award”). Recipient’s “TSR Target Share
Amount” for purposes of this Agreement is 75% of the Target Share Amount. 
  
 1.2 Strategic Award. Subject to the terms and conditions of this Agreement, the Company shall issue or otherwise deliver to the Recipient the number of shares of Common Stock of the Company (the “Strategic
Performance Shares” and, together with the TSR Performance Shares, the “Performance Shares”) determined under this Agreement based on (a) the Company’s performance against milestones during the Award Period as determined by
the Committee under Section 3 and (b) Recipient’s continued employment during the Award Period as described in Section 4. If the Company issues or otherwise delivers Strategic Performance Shares to Recipient, the Company shall
also pay to Recipient the amount of cash determined under Section 5 (the “Strategic Dividend Equivalent Cash Award” and, together with the TSR Dividend Equivalent Cash Award, the “Dividend Equivalent Cash Awards”).
Recipient’s “Strategic Target Share Amount” for purposes of this Agreement is 25% of the Target Share Amount. 

 2. TSR Performance Condition. 
  
 2.1 Subject to possible reduction under Section 4, the number of TSR Performance Shares to be issued or otherwise
delivered to Recipient shall be determined by multiplying the TSR Payout Factor (as defined below) by the TSR Target Share Amount; provided, however, that no TSR Performance Shares shall be issued or otherwise delivered unless the Company’s TSR
(as defined below) for the Award Period is at least     %. 
  
 2.2 To determine the “TSR Payout Factor,” the ten Peer Group Companies (as defined below) shall be ranked based on their respective TSR’s from highest to lowest, with the Peer Group Company with the
highest TSR having a TSR Ranking of “1” and the Peer Group Company with the lowest TSR having a TSR Ranking of “10.” If the Company’s TSR is equal to the TSR of any other Peer Group Company, the TSR Payout Factor will be the
percentage in the following table corresponding to the TSR Ranking of that Peer Group Company. 
  

			
	 TSR Ranking

	 	 TSR Payout Factor

	 10
	 	0%
	 9
	 	0%
	 8
	 	25%
	 7
	 	25%
	 6
	 	50%
	 5
	 	75%
	 4
	 	100%
	 3
	 	125%
	 2
	 	150%
	 1
	 	200%

  
 If the Company’s TSR is higher
than the TSRs of all Peer Group Companies, the TSR Payout Factor will be 200%. If the Company’s TSR is not at least as high as the TSR of the Peer Group Company with the TSR Ranking of “8,” the TSR Payout Factor will be 0%. If the
Company’s TSR is between the TSRs of any two Peer Group Companies with TSR Rankings between “1” and “8,” the TSR Payout Factor shall be interpolated as follows. The excess of the Company’s TSR over the TSR of the lower
Peer Group Company shall be divided by the excess of the TSR of the higher Peer Group Company over the TSR of the lower Peer Group Company. The resulting fraction shall be multiplied by the difference between the percentages in the above table
corresponding to the TSR Rankings of the two Peer Group Companies. The product of that calculation shall be added to the percentage in the above table corresponding to the TSR Ranking of the lower Peer Group Company, and the resulting sum shall be
the TSR Payout Factor. 
  
 2.3 The “Peer Group
Companies” are AGL Resources Inc., Atmos Energy Corporation, Cascade Natural Gas Corporation, The Laclede Group, Inc., New Jersey Resources Corporation, Nicor Inc., Peoples Energy Corporation, Piedmont Natural Gas Company, Inc., Southwest Gas
Corporation, and WGL Holdings, Inc. If prior to the end of the Award Period, the common stock of any Peer Group Company ceases to be publicly traded for any reason, then such company shall no longer be considered a Peer Group Company, and an
alternate peer company shall become a Peer Group Company effective as of the start of the Award Period. The 

  

 2 

 
alternate peer companies, and the order in which they will be added as Peer Group Companies, if necessary, are: first, South Jersey Industries, Inc.; second,
Keyspan Corporation; and third, Vectren Corporation. 
  
 2.4 The
“TSR” for the Company and each Peer Group Company shall be calculated by (a) assuming that $100 is invested in the common stock of the company at a price equal to the average of the closing market prices of the stock for the period
from October 1,          to December 31,         , (b) assuming that for each dividend paid on the stock during the Award Period, the amount equal to the
dividend paid on the assumed number of shares held is reinvested in additional shares at a price equal to the closing market price of the stock on the ex-dividend date for the dividend, and (c) determining the final dollar value of the total
assumed number of shares based on the average of the closing market prices of the stock for the period from October 1,          to December 31,         . The
“TSR” shall then equal the amount determined by subtracting $100 from the foregoing final dollar value, dividing the result by 100 and expressing the resulting fraction as a percentage. 
  
 3. Strategic Performance Condition. Subject to possible reduction
under Section 4, the number of Strategic Performance Shares to be issued or otherwise delivered to Recipient shall be determined by multiplying the Strategic Payout Factor by the Strategic Target Share Amount. The “Strategic Payout
Factor” shall be a percentage between 0% and 200% determined by the Committee after the Award Period based on the Committee’s assessment of the extent to which the Company has achieved the following goals during the Award Period:

  

	 	3.1	EPS Contribution of New Customers (Core): 

	 	·	2004: [Applicable goal] 

	 	·	2005: [Applicable goal] 

	 	·	2006: [Applicable goal] 

  

	 	3.2	Non-core Growth: 

	 	    	For 2004: 

	 	·	[Applicable goals] 

	 	·	                     

	 	    	For 2005 and 2006: 

	 	·	                     

	 	·	[Applicable goals] 

  

	 	3.3	[Applicable goal] 

  

 3 

 The Strategic Payout Factor shall be the same percentage for Recipient and all other recipients of similar awards for the
Award Period. In determining the Strategic Payout Factor, the Committee in its discretion generally will assign a percentage of 100% for satisfactory achievement of all goals, a higher percentage for exceeding expectations and a lower percentage if
goals are not achieved. 
  
 4. Employment Condition.

  
 4.1 In order to receive the full number of Performance Shares
determined under Section 2 or Section 3, Recipient must be employed by the Company on the last day of the Award Period. 
  
 4.2 If Recipient’s employment by the Company is terminated at any time prior to the end of the Award Period because of death, physical disability
(within the meaning of Section 22(e)(3) of the Code), or retirement (as defined in the Company’s Retirement Plan for Non-Bargaining Unit Employees) at or after reaching age 60, Recipient shall be entitled to receive pro-rated awards. The
number of each type of Performance Shares to be issued or otherwise delivered as a pro-rated award shall be determined by multiplying the number of Performance Shares determined under Section 2 or Section 3 by a fraction, the numerator of
which is the number of days Recipient was employed by the Company during the Award Period and the denominator of which is the number of days in the Award Period. 
  
 4.3 If Recipient’s employment by the Company is terminated at any time prior to the end of the Award Period and
Section 4.2 does not apply to such termination, Recipient shall not be entitled to receive any Performance Shares. 
  
 5. Dividend Equivalent Cash Awards. The amount of each type of Dividend Equivalent Cash Award shall be determined by multiplying the number of
Performance Shares deliverable to Recipient as determined under Sections 2 and 4 or under Sections 3 and 4, as applicable, by the total amount of dividends paid per share of the Company’s Common Stock for which the dividend record date occurred
after the beginning of the Award Period and before the date of delivery of the Performance Shares. 
  
 6. Certification and Payment. At the regularly scheduled meeting of the Committee held in February of the year immediately following the final year
of the Award Period (the “Certification Meeting”), the Committee shall determine the Strategic Payout Factor and certify in writing (which may consist of approved minutes of the Certification Meeting) the number of Strategic Performance
Shares deliverable to Recipient and the amount of the Strategic Dividend Equivalent Cash Award payable to Recipient. Prior to the Certification Meeting, the Company shall calculate the number of TSR Performance Shares deliverable and the amount of
the TSR Dividend Equivalent Cash Award payable to Recipient, and shall submit these calculations to the Committee. At or prior to the Certification Meeting, the Committee shall certify in writing (which may consist of approved minutes of the
Certification Meeting) the levels of TSR attained by the Company and the Peer Group Companies, the number of TSR Performance Shares deliverable to Recipient and the amount of the TSR Dividend Equivalent Cash Award payable to Recipient. Subject to
applicable tax withholding, the amounts so certified shall be delivered or paid (as applicable) as soon as practicable following the Certification Meeting, and no amounts 

  

 4 

 
shall be delivered or paid prior to certification. No fractional shares shall be delivered and the number of Performance Shares deliverable shall be rounded
to the nearest whole share. Notwithstanding the foregoing, if Recipient shall have made a valid election to defer receipt of Performance Shares or Dividend Equivalent Cash Awards pursuant to the terms of the Company’s Executive Deferred
Compensation Plan, payment of the award shall be made in accordance with that election. 
  
 7. Tax Withholding. Recipient acknowledges that, on the date the Performance Shares are issued or otherwise delivered to Recipient (the “Payment Date”), the Value (as defined below) on that date of
the Performance Shares (as well as the amount of the Dividend Equivalent Cash Awards) 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
these income amounts. To satisfy the required withholding amount, the Company shall first withhold all or part of the Dividend Equivalent Cash Awards, and if that is insufficient, the Company shall withhold the number of Performance Shares having a
Value equal to the remaining withholding amount. For purposes of this Section 7, the “Value” of a Performance Share shall be equal to the closing market price for Company Common Stock on the last trading day preceding the Payment
Date. Notwithstanding the foregoing, Recipient may elect not to have Performance Shares withheld to cover taxes by giving notice to the Company in writing prior to the Payment Date, in which case no Performance Shares shall be delivered to Recipient
until Recipient shall have paid to the Company in cash any required tax withholding not covered by withholding of the Dividend Equivalent Cash Awards. 
  
 8. Change in Control. 
  
 8.1 If a Change in Control (as defined below) occurs before the end of the Award Period, the Company shall, within 5 business days thereafter and subject
to applicable tax withholding as provided for in Section 7, issue or otherwise deliver to Recipient a number of Performance Shares equal to the Target Share Amount and pay to Recipient a Dividend Equivalent Cash Award based on such number of
Performance Shares. Amounts delivered or paid under this Section 8 shall be in satisfaction of any and all obligations of the Company to issue or otherwise deliver Performance Shares or pay Dividend Equivalent Cash Awards under this Agreement.

  
 8.2 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”) as a result of which the holders of outstanding securities of the Company ordinarily having the right to vote for
the election of directors (“Voting Securities”) immediately prior to the Merger do not continue to hold at least 50% of the combined voting power of the outstanding Voting Securities of the surviving corporation or a parent corporation of
the surviving corporation immediately after the Merger, disregarding any Voting Securities issued to or retained by such holders in respect of securities of any other party to the Merger; 
  

 5 

 (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 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 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
Voting Securities representing twenty percent (20%) or more of the combined voting power of the then outstanding Voting Securities. 
  
 8.3 Amendment of Prior Agreements. Recipient is a party to one or more agreements relating to prior performance-based awards under the Plan. The
definition of Change in Control in Section 7.2 of each of those prior agreements is hereby amended in its entirety and replaced by the definition in Section 8.2 of this Agreement. 
  
 9. Changes in Capital Structure. If the outstanding Common Stock of
the Company is hereafter increased or decreased or changed into or exchanged for a different number or kind of shares or other securities of the Company by reason of any stock split, combination of shares or dividend payable in shares,
recapitalization or reclassification, appropriate adjustment shall be made by the Committee in the number and kind of shares subject to this Agreement so that the Recipient’s proportionate interest before and after the occurrence of the event
is maintained. 
  
 10. Approvals. The issuance by the
Company of authorized and unissued shares or reacquired shares under this Agreement is subject to the approval of the Oregon Public Utility Commission and the Washington Utilities and Transportation Commission, but no such approvals shall be
required for the purchase of shares on the open market for delivery to Recipient in satisfaction of its obligations under this Agreement. The obligations of the Company under this Agreement are otherwise subject to the approval of state and federal
authorities or agencies with jurisdiction in the matter. The Company will use its best efforts to take steps required by state or federal law or applicable regulations, including rules and regulations of the Securities and Exchange Commission and
any stock exchange on which the Company’s shares may then be listed, in connection with the award under this Agreement. The foregoing notwithstanding, the Company shall not be obligated to issue or deliver Common Stock under this Agreement if
such issuance or delivery would violate applicable state or federal law. 
  

 6 

 11. 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. 
  
 12. Miscellaneous.

entire agreement of the parties with regard to the subjects hereof and may be amended only by written agreement between the Company and Recipient.

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. 
  
 12.3 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.
