PROPOSAL 1—ELECTION OF DIRECTORS

NW Natural’s Restated Articles of Incorporation provide that the Board of Directors be composed of not less than nine nor more than 13 directors, with the exact number of directors to be determined by the Board. The Board has fixed the number of directors at 11.

Our Chairman of the Board, Mr. Russell F. Tromley, will chair the 2011 Annual Shareholders Meeting. In February 2010, the Board reappointed Mr. Tromley as Chair of the Board of Directors and extended his term as a member of the Board pursuant to its authority under NW Natural’s bylaws and its Corporate Governance Standards. Mr. Tromley has been a director since 1994 and during that time has served on various committees. Currently, Mr. Tromley serves as Chair of the Governance Committee and as a member of the Audit Committee and the Organization and Executive Compensation Committee. Mr. Tromley became Chairman of the Board in 2008. See “Corporate Governance Standards,” below.

The Restated Articles also provide that the Board of Directors be divided into three classes and that the number of directors in each class be as nearly equal in number as possible. Members of each class are elected to serve a three-year term with the terms of office of each class ending in successive years. The term of Class III directors expires with this year’s Annual Meeting. Ms. Martha L. “Stormy” Byorum and Messrs. John D. Carter, C. Scott Gibson and Gregg S. Kantor are nominees for election to the Board as Class III directors to serve until the 2014 Annual Meeting or until their successors have been duly qualified and elected. Ms. Byorum and Messrs. Carter and Gibson were elected to the Board of Directors by the shareholders at the 2008 Annual Meeting. Mr. Kantor was elected to the Board of Directors by the shareholders at the 2009 Annual Meeting. In case any of the nominees should become unavailable for election for any reason, the persons named in the proxy will have discretionary authority to vote for a substitute. Management knows of no reason why any of the nominees would be unable to serve if elected.

Vote Required

Under Oregon law, if a quorum of shareholders is present at the Annual Meeting, the four nominees who receive the greatest number of votes cast at the meeting shall be elected directors. Abstentions and broker non-votes are counted for purposes of determining whether a quorum exists at the Annual Meeting but are not counted and have no effect on the results of the vote for directors.

The Board of Directors recommends the election of the nominees listed below.

INFORMATION CONCERNING NOMINEES

AND CONTINUING DIRECTORS

Set forth below is information with respect to the nominees and continuing directors, including their recent employment or principal occupation, a summary of their specific experience, qualifications, attributes or skills that led to the conclusion that they are qualified to serve as a director, the names of other public companies for which they currently serve as a director or have served as a director within the past five years, and their period of service as a NW Natural director, the committees on which they currently serve, and their age.

CORPORATE GOVERNANCE

THE BOARD OF DIRECTORS AND ITS COMMITTEES

Meeting Attendance

The Board of Directors conducts its annual organization meeting on the same date as the Annual Meeting of Shareholders, which all of the directors are encouraged to attend. In 2010, all of our directors attended the Annual Meeting of Shareholders.

During 2010, there were seven meetings of our Board, each of which included an executive session of non-management directors. No director attended fewer than 75 percent of the aggregate meetings of our Board and Committees on which he or she served.

Independence

The Board of Directors has adopted Director Independence Standards to comply with New York Stock Exchange (NYSE) rules. The Director Independence Standards, amended July 23, 2009, are available at www.nwnatural.com and are available in print to any shareholder who requests them. No director is deemed independent unless the Board affirmatively determines that the director has no material relationship with NW Natural either directly or as a partner, shareholder or officer of an organization that has a relationship with NW Natural. The Board applies NW Natural’s Director Independence Standards as well as additional qualifications prescribed under the listing standards of the NYSE and applicable state and federal statutes. Annually, the Board determines whether each director meets the criteria of independence. In February 2011, the Board determined that nine of the 11 directors met the independence criteria. They are directors Boyle, Byorum, Carter, Gibson, Hamachek, Peverett, Puentes, Thrasher and Tromley.

Board Nominations

The Board is responsible for selecting candidates for Board membership and the Governance Committee has been assigned the responsibility of recommending to the Board of Directors nominees for election as directors. The Governance Committee, with recommendations and input from the Chairman of the Board, the Chief Executive Officer and other directors, evaluates the qualifications of each director candidate in accordance with the Director Selection Criteria established by the Board. Candidates for director nominees are reviewed in the context of the current composition of the Board, the operating requirements of NW Natural, the existing and prospective business environment faced by NW Natural and the long-term interests of shareholders. Such director candidates must be able to make a significant contribution to the governance of NW Natural by virtue of their business and financial expertise, educational and professional background, and current or recent experience as a chief executive officer or other senior leader of a public company or other major organization. The business discipline that may be sought at any given time will vary depending on the needs and strategic direction of our Company and the disciplines represented by our incumbent directors. In addition, the Governance Committee looks at the overall composition of the Board and how a candidate would contribute to the overall synergy and collaborative process of the Board. In conducting its assessment, the Governance Committee considers a variety of criteria, including the following:

Integrity. Directors should have proven integrity and be of the highest ethical character and share NW Natural’s values.

Reputation. Directors should have reputations, both personal and professional, consistent with NW Natural’s image and reputation.

Judgment. Directors should have the ability to exercise sound business judgment on a broad range of issues.

Knowledge. Directors should be financially literate and have a sound understanding of business strategy, business environment, corporate governance and Board operations.

Experience. Directors should be or have been in a generally recognized position of leadership in the nominee’s field of endeavor and have a proven track record of excellence in their field.

Maturity. Directors should value Board and team performance over individual performance, possess respect for others and facilitate superior Board performance.

Commitment. Directors should be able and willing to devote the required amount of time to NW Natural’s affairs, including preparing for and attending meetings of the Board and its committees, and should not be over-committed by service on multiple other boards. Directors should be actively involved in the Board and its decision-making.

Skills. Directors should be selected so that the Board has an appropriate mix of skills in core areas such as: accounting, finance, government relations, technology, management, compensation, crisis management, strategic planning and industry knowledge.

Diversity. Directors should be selected so that the Board of Directors is a diverse body. “Diversity” in this context includes considerations of geographic location, gender, race and professional background.

Age. The Board’s retirement age is 70, unless otherwise determined by the Board. As such, directors must be able, and should be committed, to serve on the Board for an extended period of time.

Independence. Directors should neither have, nor appear to have, a conflict of interest that would impair the director’s ability to represent the interests of all NW Natural’s shareholders and to fulfill the responsibilities of a director.

Ownership stake. Directors should be committed to having a meaningful, long-term equity ownership stake in NW Natural and be willing to comply with our stock ownership guidelines.

Shareholder Nominations

Shareholders’ recommendations for director-nominees may be submitted to NW Natural’s Corporate Secretary for consideration by the Governance Committee. In evaluating shareholder recommendations for director-nominees, the Governance Committee applies the same Director Selection Criteria discussed above. NW Natural’s Restated Articles of Incorporation provide that no person, except those nominated by the Board, shall be eligible for election as a director at any annual or special meeting of shareholders unless a written request that his or her name be placed in nomination, together with the written consent of the nominee, shall be received from a shareholder of record entitled to vote at such election by the Corporate Secretary of NW Natural on or before the later of (a) the thirtieth day prior to the date fixed for the meeting, or (b) the tenth day after the mailing of the notice of that meeting.

Diversity

As indicated above, NW Natural’s Director Selection Criteria includes a consideration of diversity as one factor in evaluating candidates for Board membership. The Board believes that diversity with respect to factors such as background, experience, skills, geographic location, race and gender are important considerations in Board composition. The Governance

Committee discusses diversity considerations in connection with each director candidate, as well as on a periodic basis in connection with the composition of the Board as a whole. In addition, the Governance Committee and the Board conduct formal self-evaluations each year that include an assessment of whether the Governance Committee and the Board have adequately considered diversity, among other factors, in identifying and discussing director candidates. The Governance Committee believes that, as a group, the nominees contribute to the Board’s diverse range of backgrounds, experiences and perspectives.

Board Leadership Structure

The current Board leadership structure separates the role of Chairman and CEO. The Board evaluates its leadership structure and role in risk oversight on an ongoing basis. The decision to combine or separate the Chairman and Chief Executive Officer (CEO) role is determined on the basis of what the Board considers to be best for NW Natural at any given point in time. The independent Chair of the Board meets regularly with the CEO and the Corporate Secretary to discuss appropriate business to come before the Board and its committees and actively recommends agenda items for Board meetings. NW Natural’s Board is structured to promote independence. All but two members of the Board are independent directors. The independent directors of the Board meet regularly in executive sessions at which only the non- management directors are present. Under NW Natural’s bylaws, the Governance Committee, Audit Committee and Organization and Executive Compensation Committee (OECC) must be composed entirely of independent directors. All committees have an independent chair that works with the executive officer primarily responsible for work with that committee, and the Corporate Secretary, to discuss appropriate business to come before the committee and to recommend agenda items for that committee. The Board of Directors believes its leadership structure provides for appropriate independence between the Board and management.

The Governance Committee and the Board annually review the Corporate Governance Standards, which can be accessed electronically in the “Corporate Governance” section of NW Natural’s website at www.nwnatural.com, and the performance of the Board is reviewed annually by the members of the Board. The Corporate Governance Standards describe the Board’s primary responsibilities, which include oversight of NW Natural’s mission, and key programs that enable the Board to assess and manage material risks, including ethics and compliance, operational risk, strategic planning, financial performance, compensation and CEO succession.

Committees

There are six standing committees of the Board: Audit, Finance, Governance, Organization and Executive Compensation, Public Affairs and Environmental Policy, and Strategic Planning. Each of the committees operates according to a formal written charter, all of which are reviewed annually and are available at www.nwnatural.com. Copies of the charters are also available in print to any shareholder upon request. The performance of each committee is reviewed annually. Each committee may obtain advice and assistance from internal or external legal, accounting or other advisors, when appropriate, and each committee has the opportunity to meet in executive session with non-management directors at the end of each committee meeting.

Audit Committee

The Audit Committee is composed of directors Byorum, Carter, Hamachek, Peverett, Thrasher and Tromley, each of whom is an independent director as defined under current NYSE listing standards and NW Natural’s Director Independence Standards. Based on its review of relevant information, the Board has determined that Mr. Carter is an “audit

committee financial expert” and “independent” as those terms are defined under applicable Securities and Exchange Commission (SEC) rules. Mr. Carter serves as Chair of the Audit Committee and was appointed to that position in May 2005.

The Audit Committee is responsible for overseeing matters relating to accounting, financial reporting, internal control, auditing, and NW Natural’s Enterprise Risk Management process.

The Governance Committee, which serves as the nominating committee, makes recommendations to the Board regarding nominees for election to the Board, establishes criteria for Board and committee membership and policies that govern the Board’s activities, including the Corporate Governance Standards discussed below, and evaluates Board and individual director performance. It also considers any questions of possible conflicts of interest of Board members and senior executives and, jointly with the Organization and Executive Compensation Committee, considers CEO succession plans. The Governance Committee is composed of directors Carter, Gibson, Hamachek and Tromley, each of whom is an independent director as defined under current NYSE listing standards and NW Natural’s Director Independence Standards. Mr. Tromley was appointed chair of the Governance Committee in May 2008, and he presides at all executive sessions of the Governance Committee and executive sessions of the non-management directors of the Board in which he is in attendance. The Governance Committee held seven meetings in 2010.

Organization and Executive Compensation Committee

The Organization and Executive Compensation Committee (OECC) reviews the performance of the CEO and other executive officers, makes recommendations to the Board relating to executive compensation programs and benefit plans, and monitors risks related to such programs and plans. The OECC oversees the administration of the Restated Stock Option Plan, the Long Term Incentive Plan, the Executive Deferred Compensation Plan, the Executive Annual Incentive Plan, the Directors Deferred Compensation Plan and the Deferred Compensation Plan for Directors and Executives. The OECC also makes recommendations to the Board regarding Board compensation, and organization and executive succession matters. The OECC is composed of directors Gibson, Peverett, Thrasher and Tromley, each of whom is an independent director as defined under current NYSE listing standards and NW Natural’s

Director Independence Standards. Each member of this OECC also meets the criteria for a “non-employee director” under applicable SEC rules and the criteria for “outside directors” under Section 162(m) of the Internal Revenue Code of 1986, as amended (Internal Revenue Code). Mr. Gibson was appointed Chair of the OECC in May 2008 and he presides at all executive sessions of the OECC in which he is in attendance. The OECC held four meetings in 2010.

Public Affairs and Environmental Policy Committee

The Public Affairs and Environmental Policy Committee reviews NW Natural’s policies and practices relating to significant public and political issues that may impact our business operations, financial performance or public image. The Public Affairs and Environmental Policy Committee oversees our programs and policies relating to civic, charitable and community affairs, safety, and equal employment opportunities. It also reviews and recommends to the Board appropriate environmental policies and informs the Board concerning the status of our compliance with environmental regulations, as well as oversees our administrative and litigation matters related to our environmental liabilities. The Public Affairs and Environmental Policy Committee makes recommendations to the Board to ensure that we fulfill our objectives in a manner consistent with the responsibilities of good corporate citizenship. It is composed of directors Boyle, Dodson, Gibson, Puentes and Thrasher. Mr. Thrasher serves as Chair and was appointed to that position in May 2008 and he presides at all executive sessions of the Public Affairs and Environmental Policy Committee in which he is in attendance.

Mr. Hamachek presides at all executive sessions of the Strategic Planning Committee in which he is in attendance. The Strategic Planning Committee held two meetings in 2010.

Board’s Role in Risk Oversight

NW Natural’s management is responsible for the day-to-day management of risks faced by the Company, while the Board of Directors, collectively and through its committees, has responsibility for the oversight of risk management. The Board periodically reviews its committee risk oversight structure to ensure the Board has adequate oversight coverage and visibility of the Company’s key risks. NW Natural’s independent Audit Committee, which regularly reports to the full Board, has primary responsibility for oversight and evaluation of the Company’s policies with respect to significant risks and exposures faced by the Company and the procedures for assessing, monitoring and managing those risks. Under the terms of its charter, the Audit Committee’s duties include responsibility for oversight of the independent auditor, internal audit, financial reporting, as well as the Company’s Ethics and Compliance program, including the Code of Ethics and its system for review and treatment of complaints regarding accounting or financial irregularities and ethical violations. The Audit Committee also reviews NW Natural’s quarterly financial filings, including the disclosure of NW Natural’s risk factors. The Audit Committee also has oversight responsibility for the Company’s annual

enterprise risk management assessment process. In fulfilling its risk oversight function, the Audit Committee periodically and as needed discusses key risks with NW Natural’s Chief Executive Officer, Chief Financial Officer, legal counsel, internal auditors, and with its independent registered public accounting firm.

In addition to receiving regular reports from the Audit Committee with respect to its risk oversight responsibilities, the Board reviews key risks associated with the Company’s strategic plan at its annual strategic planning session and periodically throughout the year through reports received from its Strategic Planning Committee. Other committees having a significant risk oversight role include the Finance Committee, which has primary responsibility for the financial strategy and policies of the Company, including risk oversight of its capital structure and liquidity, and the Public Affairs and Environmental Policy Committee, which has primary responsibility for overseeing the Company’s strategy related to the Company’s current and potential environmental liabilities, as well as legislative and regulatory risks. In addition, management attends Board and committee meetings and regularly discusses with the Board and the committees various risks confronting the Company.

NW Natural’s Board also manages its executive compensation oversight risk responsibility through the independent OECC, which regularly reports to the full Board. Under the terms of its charter, the OECC is responsible for overseeing the Company’s executive compensation programs and plans to ensure consistency with corporate objectives and its compensation philosophy. In fulfilling its compensation risk oversight function, the OECC discusses with its outside consultant key compensation design elements of the Company’s compensation plans and awards, including, but not limited to, whether those plans and awards properly incentivize executive performance, promote retention of valuable executives, and disincent inappropriate risk-taking. For additional information regarding the OECC oversight of executive compensation, see “Executive Compensation—Compensation Discussion and Analysis—Overview—Organization and Executive Compensation Committee,” below.

CORPORATE GOVERNANCE STANDARDS

The Board of Directors maintains Corporate Governance Standards that provide NW Natural and its Board of Directors with guidelines designed to ensure that business is conducted with the highest level of integrity. The Corporate Governance Standards are reviewed annually by the Governance Committee to determine if changes should be recommended to the Board of Directors. The Corporate Governance Standards, amended July 23, 2009, are available at www.nwnatural.com and are available in print to any shareholder who requests a copy. Among other matters, the Corporate Governance Standards include the following guidelines:

A substantial majority of the Board should be independent as determined annually by the Board in accordance with NW Natural’s Director Independence Standards.

The Governance Committee, the Audit Committee and the Organization and Executive Compensation Committee consist entirely of independent directors, as that term is defined by NYSE listing standards and NW Natural’s Director Independence Standards.

The Governance Committee recommends director nominees to the full Board in accordance with the Director Selection Criteria.

Unless otherwise determined by the Board, directors must retire from the Board at the first annual meeting of shareholders after reaching age 70. See “Proposal 1—Election of Directors,” above.

In addition, the Governance Committee annually conducts peer reviews of directors prior to the end of their term of office.

Annually, the Board reviews and approves the strategic plan and one-year capital expenditure plans.

The Governance Committee recommends committee members for appointment by the Board and committee membership is periodically rotated.

The Board provides an opportunity for an executive session of non-management directors at the end of each Board meeting; the Chair of the Board presides at these executive sessions.

The CEO reports at least annually to the Board regarding succession planning and management development. The OECC is responsible for succession planning and submitting its recommendations to the Board of Directors with respect to CEO selection, and is responsible, in consultation with the Governance Committee, for selecting the CEO.

The OECC recommends to the Board reasonable director compensation. Directors who are also employees of NW Natural receive no additional compensation for their service as directors.

Concerns may be submitted in writing to the non-management directors of NW Natural, c/o Corporate Secretary, 220 NW Second Avenue, Portland OR 97209. Employees and other third parties may also submit concerns anonymously pursuant to the Code of Ethics’ hotline, 1-866-546-3696, also located at our internal website. Our Director of Internal Audit handles matters reported on the internal hotline in coordination with our Chief Compliance Officer and regularly reports to the Audit Committee on hotline activity.

The Corporate Secretary will refer concerns that come directly before the Corporate Secretary or Chief Compliance Officer relating to accounting, financial reporting, internal controls or auditing matters to the chair of the Audit Committee, and other concerns to the chair of the Governance Committee as appropriate. The Corporate Secretary regularly reports to the Governance Committee regarding concerns submitted to the non-management directors of NW Natural, if any.

SECTION 16(a) BENEFICIAL OWNERSHIP REPORTING COMPLIANCE

Section 16(a) of the Securities Exchange Act of 1934, as amended, requires NW Natural’s directors and executive officers to file initial reports of ownership and changes in ownership of NW Natural Common Stock with the SEC. Based solely on a review of the copies of reports furnished to us and written representations that no other such reports were required, we believe that all directors and executive officers timely filed all reports required under Section 16(a) of the Securities Exchange Act of 1934, as amended.

COMPENSATION COMMITTEE INTERLOCKS AND INSIDER PARTICIPATION

There are no “Compensation Committee interlocks” or “insider participation,” which SEC regulations or NYSE listing standards require to be disclosed in this proxy statement.

TRANSACTIONS WITH RELATED PERSONS

The Board adopted a written policy on the review of related person transactions (Transactions with Related Persons Policy) specifying that certain transactions involving directors, nominees, executive officers, significant shareholders and certain other related persons in which NW Natural is or will be a participant, and are of the type required to be reported as a related person transaction under Item 404(a) of SEC Regulation S-K, shall be reviewed by the Audit Committee. Pursuant to its charter, the Audit Committee is responsible for reviewing related person transactions.

Under the Transactions with Related Persons Policy, the Audit Committee reviews the material facts and circumstances of any transaction that may require reporting under Item 404(a) of SEC Regulation S-K to determine: (i) whether or not the transaction is on terms comparable to those that could be obtained in arm’s length dealings with an unrelated third party; or (ii) whether or not the transaction is otherwise in the best interest of the Company. Upon review of a transaction, the Audit Committee may approve or disapprove the transaction and direct the officers of the Company to take appropriate action. In the event the Audit Committee is not otherwise convening, the transaction may be approved or ratified by the majority of disinterested members of the Board of Directors. We are not aware of any transactions entered into during the last fiscal year that did not follow the procedures outlined in the policy.

Compensation to Spouse of a Named Executive Officer

Ted Smart, the husband of Lea Anne Doolittle, Senior Vice President, has been an employee of NW Natural since February 2006. In November 2006, Mr. Smart moved from his position as a senior auditor to purchasing manager. Ms. Doolittle was not involved in decisions regarding Mr. Smart’s hiring, promotion or compensation. Cash compensation paid to Mr. Smart in 2010 was approximately $143,000 and is expected to be approximately $148,000 in 2011. Mr. Smart reports to David Anderson, Senior Vice President and Chief Financial Officer. Compensation paid to Mr. Smart is reviewed periodically by the Audit Committee in accordance with our Transactions with Related Persons Policy.

EXECUTIVE COMPENSATION

REPORT OF THE ORGANIZATION AND EXECUTIVE COMPENSATION COMMITTEE

The Organization and Executive Compensation Committee of the Board of Directors (OECC) is responsible for discharging the responsibilities of the Board of Directors relating to the compensation of executives by ensuring that the Chief Executive Officer and other senior executives are compensated appropriately and in a manner consistent with the stated compensation philosophy of NW Natural and the requirements of the appropriate regulatory authorities.

The OECC is responsible for producing this report and for providing input and guidance to management in the preparation of the Compensation Discussion and Analysis following this report. In fulfilling its responsibilities, the OECC has reviewed and discussed the Compensation Discussion and Analysis with management.

In reliance on the review and discussion referred to above, the OECC recommended to the Board of Directors (and it has approved and directed) that the Compensation Discussion and Analysis be included in this proxy statement and incorporated by reference into NW Natural’s Annual Report on Form 10-K for the year ended December 31, 2010.

Respectfully submitted on February 23, 2011 by the Organization and Executive Compensation Committee of the Board of Directors:

COMPENSATION DISCUSSION AND ANALYSIS

Overview

Organization and Executive Compensation Committee

The Organization and Executive Compensation Committee (OECC) operates pursuant to a written charter that is available at www.nwnatural.com. Under the charter, the OECC is primarily responsible for:

discussing and reviewing the management and affairs of NW Natural relating to its organization and to executive personnel and their compensation;

producing an annual compensation committee report for inclusion in NW Natural’s proxy statement; and

providing input and guidance to management in the preparation of the Compensation Discussion and Analysis also to be included in NW Natural’s proxy statement.

The OECC also periodically reviews with the Chief Executive Officer and the Senior Vice President responsible for human resources NW Natural’s succession planning process, including the identification of potential internal and external candidates for executive positions. The OECC’s policies and decisions applicable to the compensation of all of the Named Executive Officers (listed below) are generally similar in all material respects.

Delegation of Authority. The Board of Directors has delegated to the OECC its full authority to grant stock options under the terms of the Restated Stock Option Plan and to grant awards under the terms of the Long Term Incentive Plan. Both of these plans have been approved by our shareholders. With respect to other components of the Named Executive Officers’ compensation, the OECC submits its recommendations to the Board for approval. Day-to-day administration of director and executive compensation plans has been delegated, under the terms of the plans, which have been approved either by shareholders or the Board of Directors, to certain officers, with oversight provided by the OECC.

Management’s Role. Management provides support to the OECC in a number of ways to facilitate executive compensation decisions, including working with counsel on plan design changes, preparing reports and materials, communicating with outside advisors, administering plans and implementing the Board’s and OECC’s decisions. The Senior Vice President responsible for human resources is the primary management contact for the OECC. The Chief Executive Officer makes recommendations to the OECC regarding plan design, salary increases, incentive awards and other executive compensation decisions for executives other than himself.

Use of Consultants. The OECC has engaged Towers Watson, an independent compensation consulting firm (Consultant), to assist in the evaluation of the competitiveness of our executive compensation programs and to provide overall guidance to the OECC in the design and operation of these programs. The Consultant reports directly to the OECC chair, and the chair reviews all invoices submitted by the Consultant. At the direction and under the guidance of the OECC chair, the Consultant provides data and analysis that is used by both management and the OECC to develop recommendations for executive compensation and executive programs to submit to the OECC for its consideration.

Our Named Executive Officers

For purposes of this report, our Named Executive Officers include the following individuals:


Name		Title
Gregg S. Kantor		President and Chief Executive Officer
David H. Anderson		Senior Vice President and Chief Financial Officer
Lea Anne Doolittle		Senior Vice President
J. Keith White		Vice President, Business Development and Energy Supply and Chief Strategic Officer
Margaret D. Kirkpatrick		Vice President and General Counsel

Our Compensation Philosophy

The OECC has adopted a total compensation philosophy centered on pay for performance to guide its decisions with respect to executive compensation. Each year, including 2010, the OECC reviews, makes changes or corrections as necessary, and reaffirms its compensation philosophy. The guiding principles of this philosophy are to design executive compensation programs that:

ensure that we have the ability to attract, retain and motivate talented and qualified executives critical to the achievement of our annual goals, our long-term business strategy and objectives, and the enhancement of shareholder value by providing total remuneration, including base salary, incentive compensation, benefits and retirement income, at a level that is competitive with that of other energy service and general industry companies, as applicable, of comparable size and circumstances;

motivate high levels of performance by linking a significant portion of each executive’s total direct compensation opportunity, which includes base salary and annual and long-term incentives, to Company performance using the achievement of previously-established annual and long-term performance goals, and by including components of compensation opportunity that are at risk subject to the achievement of established performance criteria;

promote creation of shareholder value by requiring meaningful stock ownership by officers (see “Stock Ownership Guidelines,” below), and by providing a significant component of compensation that is based on earnings growth and stock price performance (see “Compensation Programs—Long-Term Incentives,” below) to align executives’ long-term interests with those of our shareholders;

pay for performance and the right results by driving the achievement of our business strategy while creating shareholder value, operating within the established risk profile of NW Natural, and providing a significant portion of pay through incentive compensation programs that are tied to NW Natural strategies and objectives;

achieve the correct balance by providing compensation that is attractive to executives, affordable to NW Natural, proportional to the executive’s contribution, and fair to shareholders and employees, while providing a payout that is aligned with actual performance, balances short- and long-term incentive measures, and uses multiple incentive measures where appropriate; and

align pay practices with shareholder interests with an eye toward remaining competitive, and use risk analysis and mitigation to provide compensation practices that motivate appropriate risk-taking, by, for example, providing compensation incentives for achievement of certain identified Company objectives and goals, while disincenting unnecessary risk-taking, by, for example, including “clawbacks” from certain executive officers’ compensation under certain plans and awards in the event of misconduct.

The OECC has taken a number of actions in recent years in furtherance of its total compensation philosophy, including, but not limited to:

eliminating perquisites for executives;

eliminating change-in control severance gross-up payments;

establishing a policy whereby potential change-of-control severance payments decline in amount as an executive nears retirement age;

reducing the interest crediting rate on compensation deferred after 2004 to a variable market rate;

modifying the Executive Supplemental Retirement Income Plan (ESRIP) and Supplemental Executive Retirement Plan (SERP) to reduce benefits and expenses, including limiting the amount of an executive’s annual bonus that is included in final average compensation for purposes of those plans and eliminating the annual payment of ESRIP-related FICA tax on behalf of ESRIP participants;

closing new participation in the ESRIP and SERP Tier I;

establishing guidance to discontinue use of employment contracts and provide limited use and duration of non-change-in-control severance; and

increasing the percentage of total target direct executive compensation that is at-risk, particularly for the Chief Executive Officer.

Highlights of 2010 OECC Actions

In 2010, the OECC took the following significant actions with respect to our executive compensation programs and practices:

implemented decisions made in late 2009 to add new requirements to “clawback” from executive officers certain benefits under annual and long-term incentive awards in the event of misconduct (see “Clawback Provisions”);

conducted a thorough request for proposal with six executive compensation consulting firms, and after considering quality of services, price, knowledge of industry policies and procedures in place to prevent conflicts and other factors, decided to retain the current consultant, Towers Watson; and

reviewed, analyzed and considered whether the Company’s compensation policies and practices create risks that are reasonably likely to have a material adverse effect on NW Natural, and concluded that no such material risks were identified.

Elements and Objectives of our Executive Compensation Program

At the core of our total compensation philosophy is pay for performance through the use of both annual and long-term incentives. The elements and objectives of the executive compensation program for the Named Executive Officers are described below:


Compensation Element	Objective(s)	Key Features

*Base Salaries*	• Reflect executives’ performance in demonstrating leadership competencies. • Recognize that certain aspects of executives’ leadership roles cannot be measured as objectively as other functions for purposes of meeting performance measures under incentive pay programs.	• Targeted at 50th percentile of the applicable survey data, on average, except that CEO is targeted below 50th percentile to have a greater percentage of pay at risk and tied to Company performance. • Adjustments are made based upon the value of the position to the business, the performance of the individual, and pay relative to the market.

*Executive Annual Incentive Plan*	• Encourage and reward executive officers’ contributions in achieving our annual goals, including financial, operating and individual performance goals	• Annual incentive cash payments are based on a formula that includes earnings per share, return on invested capital, Company performance relative to other operational goals, and individual performance.

*Long-term incentive awards*	• Provide executives with an incentive to work toward increasing the price of our Common Stock. • More closely align executives’ interests with shareholders’ interests. • Reward relative total shareholder return performance to the Company’s peer group. • Focus the executives on key long-term objectives and long-term business results that align with the creation of shareholder value.	• We seek to have the expected value of long-term incentives granted to executive officers be approximately 20-25 percent in the form of stock options and approximately 75-80 percent in the form of performance share awards. • Performance share awards have a performance period of three years and are based 75 percent on total shareholder return and 25 percent on achievement of performance milestones relative to strategic plan goals. • Stock options are granted at market and vest in annual increments generally over the first four years after the grant date.


Compensation Element	Objective(s)	Key Features
*Executive health, welfare and retirement benefits*	• Provide executives reasonable and competitive benefits. • Encourage savings for retirement. • Allow for attraction and retention of experienced mid-career hires. • Mitigate the impact of limits on qualified plan benefits imposed by the Internal Revenue Code.	• Health and welfare benefits consistent with standard benefits provided to non-bargaining unit employees. • 401(k) plan and non-qualified deferred compensation plans allow for deferral of compensation and Company matching contributions on such deferrals. • Qualified pension plan for persons employed prior to 2007, including all Named Executive Officers, and supplemental non-qualified pension benefits with lower benefit levels for newer executive officers.

*Change-in-control arrangements*	• Ensure attention and dedication to performance without distraction in the circumstance of a potential change in control of NW Natural. • Enables executives to maintain objectivity with respect to merger or acquisition offers considered by the Board.	• Double trigger change in control severance agreements. • Declining levels of benefits as executive approaches age 65.

Pay for Performance

2010 was a strong year for NW Natural. Full year 2010 operating results were among the highest in the Company’s history with earnings of $2.73 per share. NW Natural achieved a ranking of highest in the nation among gas utilities for residential customer satisfaction. The Company also reduced its operations and maintenance expenses 5 percent for the year as compared to 2009, and customer gas rates declined in Oregon and Washington for the second year in a row. Moreover, the Gill Ranch Storage facility near Fresno, California commenced operations in the fall of 2010. The Company’s strong performance was reflected in an average payout to NEOs of 132.66 percent under the Executive Annual Incentive Plan, which is designed to tie executive compensation to executive officers’ contributions in achieving NW Natural’s annual goals, including financial, operating and individual performance goals. Factors contributing to the higher than targeted payout under the Executive Annual Incentive Plan include, among other things, achievement of earnings per share (EPS) of $2.73, which was 8 cents higher than the target EPS for the year, achievement of a return on invested capital (ROIC) of 8.32 percent, which was higher than the targeted ROIC of 7.95 percent and achievement of several other operating goals established in pre-set targets.

Despite NW Natural’s strong annual performance, executive officers received a payout of only 23.94 percent from their performance share awards under the Long Term Incentive Plan for the 2008-2010 award cycle. The payout was low because the total shareholder return

component factor, which comprises 75 percent of our performance share award, resulted in a zero percent payout factor, due to a total shareholder return for the period that was below the plan threshold and below the ninth best performing company in the plan’s assigned peer group of ten companies. The OECC assigned a rating of 95.75 percent to the remaining 25 percent of the performance share awards reflecting, among other things, strong financial performance, including cost-effective operation of our core business in a low-growth environment offset by certain challenges surrounding budget overruns on construction of the Gill Ranch storage facility and difficult market conditions in the gas storage markets generally.

Market Position

The OECC seeks to achieve its executive compensation program’s objectives by positioning total executive compensation, consisting of annual base salary, annual incentives, long-term incentives and benefits, at or near the 50^th percentile of the applicable competitive market. The OECC has determined that using the 50^th percentile of competitive market surveys as a guide for establishing executive compensation will provide us with the ability to attract and retain the best possible executive talent at or near competitive standards for comparable positions in the competitive market for each executive position. Although the total remuneration program is designed to pay compensation at the middle of the competitive market, the program contains several variable components, which allow compensation to exceed median competitive pay levels when the performance expectations of the OECC are exceeded; conversely, the program provides less than median competitive compensation when performance does not meet those expectations.

We are likely to attract candidates for most executive positions from the energy service market, specifically, from gas and electric companies with similar revenue size in the United States. However, general industry market information may be considered for certain executive positions that can be found in any industry. The OECC reviews all components of executive compensation (including salary, annual incentives, equity and long-term incentive compensation, health, welfare, and other benefits, as well as the dollar value and cost of all benefits under our qualified and non-qualified deferred compensation and supplemental retirement plans) and compares them to the applicable competitive market for each executive officer every two years, including 2009 and 2011. The direct compensation components (salary and annual and long-term incentives) are compared to the applicable competitive market for each executive officer annually. The market data used in these comparative analyses are generally obtained from salary survey databases compiled by the Consultant, industry associations or other general industry sources.

In preparing its competitive market assessment, the Consultant employs a methodology that focuses on survey data for energy service companies with annual revenues of $500 million to $3.0 billion, which is an annual revenue range and industry group that the Consultant has determined to be appropriate. The Consultant also provides survey data for general industry companies within the same annual revenue range. The Consultant collects and updates 50^thpercentile data from compensation surveys for base salaries, annual incentives and long-term incentives annually. The Consultant selects the most appropriate market comparisons for each executive position and synthesizes that data to provide to the OECC for its review. Named Executive Officers’ positions are matched to survey benchmarks based on functional responsibilities. Survey data used in this analysis includes the American Gas Association, “Executive Compensation Survey Results”, Towers Perrin “Energy Services Executive Survey”, and Towers Perrin “General Industry Executive Compensation Survey.”

In addition to looking at survey data to understand competitive market pay, the Consultant also provided the OECC with supplementary data in February 2010 for the Chief Executive

Officer, Chief Financial Officer, General Counsel, and the two to five other most highly paid executives from the following 13 natural gas industry companies, as reported in their most recent proxy statements:


AGL Resources Inc.		Ni Source Inc.
Atmos Energy Corp.		Piedmont Natural Gas Company Inc.
Chesapeake Utilities Corp.		South Jersey Industries Inc.
Laclede Group Inc.		Southwest Gas Corp.
National Fuel Gas Co.		Vectren Corp.
New Jersey Resources Corp.		WGL Holdings
Nicor Inc.

While the OECC considers data from these natural gas industry companies, it focuses on the survey data, rather than the proxy data, because the majority of the companies in the proxy group are larger than NW Natural as measured by revenues, and because proxy data is provided by position title, rather than position function, the latter of which the OECC has determined is more meaningful. While the median revenues for the proxy data peer group are $2.5 billion, some of the companies in the proxy data group may be included in one or more of the survey data groups, if their annual revenues are comparable to NW Natural’s.

Tally Sheets

Every year the OECC reviews the total remuneration of executives in the form of a tally sheet prepared by our human resources department and reviewed by outside consultants (legal, actuarial and compensation), which shows each executive’s current total compensation from all sources, including probability of attainment weighted potential compensation from equity awards not yet earned, as well as retirement benefits, along with possible compensation from any severance arrangements, including change in control compensation. The OECC also uses tally sheets to review the potential impact of any significant plan change. In its most recent review of tally sheets, the OECC determined that each executive’s compensation remained consistent with the OECC’s expectations and no changes to pay programs or practices were recommended.

Stock Ownership Guidelines

Our Corporate Governance Standards provide the following ownership guidelines for executive officers, expressed as a multiple of each executive officer’s base salary:


Position	Dollar Value of Stock Owned as Multiple of Base Salary
Chief Executive Officer		2x
Executive and Senior Vice Presidents		1.5x
All other executive officers		1x

The OECC reviewed and reaffirmed the stock ownership requirements for executive officers as of December 31, 2010. The Board of Directors of NW Natural believes that these ownership objectives provide executives with a meaningful stake in the ownership of NW Natural and, as a result, fully align executive officers’ interests with those of our shareholders. The stock ownership objectives should generally be attained within five years of appointment as an officer. The OECC annually reviews the progress made by executives against these objectives. This progress is measured using both shares owned directly by executives as well as shares credited to their Retirement K Savings Plan (401(k) Plan) and non-qualified deferred compensation plan accounts and is determined using the average daily closing price for the

Common Stock over the preceding calendar year. The OECC last reviewed the progress of the Named Executive Officers in achieving these stock ownership objectives in February 2011 and concluded that all of the Named Executive Officers have achieved stock ownership goals or, for newer officers, have made satisfactory progress in achieving these goals given the time they have served in their respective executive positions. The Company does not have a policy that requires retention of stock acquired from equity compensation plans or vesting of shares.

Compensation Programs

How Compensation Decisions Are Made

Competitive data is used as a guide to make compensation decisions, along with other relevant considerations including corporate and individual performance, an executive’s experience and contribution, as well as the relative relationship of an executive’s responsibilities to other executive roles. Our executive compensation programs are sufficiently flexible to allow pay relative to the market median to vary by individual position if warranted by special circumstances. These special circumstances might include strong individual performance, marketability of skills, or retention considerations that could allow certain executives to receive higher than the average compensation increases for the industry or higher incentive awards in recognition of these special considerations. The Chief Executive Officer considers this type of information prior to recommending to the OECC salary, and annual and long-term incentive compensation levels for the other Named Executive Officers. The OECC then considers the Chief Executive Officer’s recommendations with respect to the other Named Executive Officers and completes its own evaluation and recommendation with respect to the Chief Executive Officer, considering competitive data prepared by the Consultant in both instances.

The OECC also considers the Consultant’s advice, including information from the Consultant’s competitive analysis and survey, to determine:

the inclusion of the various compensation program elements;

policies for allocating between long-term and currently paid compensation;

policies for allocating between cash and non-cash compensation, and among the different forms of non-cash compensation; and

the basis for allocating to each of the two primary types of long-term compensation award opportunity.

The OECC’s policy is to establish the allocations between long-term and currently paid compensation, and between cash and non-cash compensation (including the allocation among different forms of non-cash compensation), in approximately the same manner as the median of the applicable competitive market for comparable executive positions. The OECC also evaluates the total remuneration package for each executive to consider whether those compensation packages encourage unnecessary or inappropriate risk-taking on the part of the executive or the Company, such as by encouraging behavior that focuses on short-term results at the expense of long-term value, and whether the compensation package encourages meaningful ownership by each executive to align that executive’s interests with that of the shareholders.

Current vs. At-Risk Compensation

An executive’s base salary is intended to reflect the value of the executive’s position to our Company and provide a competitive foundation for the work being performed. The remainder of the total direct compensation is at risk and must be earned by achieving short-term and

long-term performance goals, which are intended to increase shareholder value. See “Long-Term Incentives” below for a brief description of how NW Natural determines the “expected value” of long-term incentives. The portion of total direct compensation designed to be paid in base salary versus variable pay depends upon the executive’s position and the ability of that position to influence outcomes, as well as market factors. The Chief Executive Officer has the largest portion of pay at risk, and the OECC’s current compensation strategy for the Chief Executive Officer is to continue to increase the percentage of his pay at risk. In 2010, the percentage of targeted total direct compensation opportunity at risk or earned by achieving performance goals was approximately 71 percent for the Chief Executive Officer, and, for the other Named Executive Officers, the average percentage of such compensation at risk was approximately 51 percent. The remaining portion of direct compensation is delivered in the form of base salary.

2010 Base Salaries

Base salaries paid to executives are established by the Board of Directors, on recommendation of the OECC, based upon the value of the position to the business, the performance of the individual and consideration of the market salary analyses prepared by the Consultant. As described above, these analyses include salary survey and proxy data for comparable positions at similarly-sized energy service and general industry companies. Salaries are typically adjusted March 1 of each year.

The following table shows the salaries of the Named Executive Officers before and after 2010 salary adjustments went into effect on March 1, 2010. The Named Executive Officers received salary increases ranging from 2.4 percent to 3.2 percent, generally consistent with the average salary increase for non-union employees of 2.75 percent for 2010. For his second year as Chief Executive Officer, Mr. Kantor’s salary continued to be under the 50^th percentile salary for energy service company chief executive officers, at 81 percent of the 50^th percentile. Mr. Kantor presented his request to the OECC that any base salary increase be generally consistent with increases made for other employees. The OECC chose to substantially increase the expected value of his long-term incentives in lieu of a more significant salary increase, consistent with Mr. Kantor’s request and the OECC’s strategy to increase the portion of his compensation at risk subject to the Company’s long-term performance. The salary survey data reviewed by the OECC in early 2010 for the other Named Executive Officers reflected small increases from the similar data reviewed in early 2009, so salaries for Ms. Kirkpatrick and Mr. White remained near the 50th percentile of the energy service company survey data for their positions, and the salaries for Mr. Anderson and Ms. Doolittle remained at or about the mid-point between the energy service and general industry survey data medians for their positions, consistent with the OECC’s ongoing view that these two positions should be competitive with and partially reflect the higher median salaries paid by general industry companies.


Name	Salary Effective March 1, 2009		Salary Effective March 1, 2010
Gregg S. Kantor	$	446,000	$	456,570
David H. Anderson		343,000		353,000
Lea Anne Doolittle		240,000		247,000
J. Keith White		220,000		227,000
Margaret D. Kirkpatrick		262,000		270,000

The following discussion and analysis contains statements regarding individual and corporate performance measures, targets and goals. These measures, targets and goals are used for purposes of executive incentive compensation programs, and in some cases incentive compensation programs that are available to all NW Natural employees. These measures, targets and goals are disclosed in the limited context of NW Natural’s compensation programs and should not be understood to be statements of management’s representations of Company financial performance for the periods covered. The results reported with respect to these incentive compensation programs are used specifically for executive incentive compensation programs, and NW Natural cautions investors not to apply these statements to other contexts. Furthermore, these prior results are not intended to be and are not indicative of the Company’s future financial performance.

Executive Annual Incentive Plan

The Executive Annual Incentive Plan is designed to tie executive pay to Company performance by incenting key executives to achieve our annual goals, including financial, operating and individual performance goals. Awards are paid by March 15 of the following year if the OECC determines the goals are achieved. Although the OECC has discretion to increase an award up to a maximum of 150 percent of the target or to reduce an executive’s performance-based award, it has not determined the need to increase or decrease awards under this plan to date.

In 2009, we modified this plan to generally provide that in the event of a restatement of the Company’s financial statements due to misconduct of any person, all participants must repay to the Company the difference between the bonus received for the affected year and the amount of bonus that would have been received if calculated based on the financial statements as restated, as well as to preclude any payout or benefit following termination of employment for any participant who is terminated for cause.

We believe this program supports our compensation objective of motivating executives to achieve high levels of performance. Participation in the plan currently is limited to 12 participants selected by the OECC, including the Named Executive Officers.

Target awards for executives vary as a percent of base salary based on the executive’s position. The 2010 bonus target percentages for all Named Executive Officers except Mr. White remained the same as 2009 levels. Mr. White’s target award percentage increased from 35 percent in 2009 to 40 percent in 2010 to reflect his increased accountability for business development initiatives, including gas storage. Target and actual awards in dollars and as a percent of base salary (in effect on December 31, 2010) for 2010 incentive awards paid in 2011 were as follows:


Named Executive Officer	Target Award Percentage			Target Award Amount		Actual Award Percentage			Actual Award Amount
Gregg S. Kantor		70	%	$	319,599		94	%	$	428,000
David H. Anderson		45	%		158,850		60	%		211,000
Lea Anne Doolittle		35	%		86,450		48	%		119,000
J. Keith White		40	%		90,800		50	%		114,000

When added to base salaries, the amounts payable upon achievement of these goals are intended to place executives’ compensation at the 50^th percentile of total cash compensation for applicable comparable energy service industry positions included in the Consultant’s survey data and analyses, except that Mr. Anderson and Ms. Doolittle have target total cash

compensation at or about the midpoint between the energy service and general industry medians for their positions, which is consistent with their salary positioning, and Mr. Kantor’s target total cash compensation is about 85 percent of the energy service median (50^th percentile) for his position, also consistent with his salary positioning. Consistent with our philosophy that executives should be paid in accordance with the performance of the Company, when goals are exceeded, it is expected that executives’ compensation will be above these levels; conversely if goals are not achieved, executives’ compensation will be below these levels. For information on the performance-based portion of specific awards granted to each Named Executive Officer, see the “Grants of Plan-Based Awards During 2010” table below.

The OECC has given considerable attention to what performance measures are appropriate for the executive incentive plans, and reviews these measures at least annually. Changes may be made to the measures at the start of new performance periods if the OECC determines that changes are appropriate. For 2010, awards under the Executive Annual Incentive Plan reflect a focus on compensation for Company performance, with an allocation of 75 percent to corporate performance goals (EPS, return on invested capital and certain operating goals) and an allocation of 25 percent to individual performance criteria established for each executive. The formula for the total incentive award is as follows:

Corporate Performance Goals. In 2010, the corporate performance goals established by the OECC for the Executive Annual Incentive Plan were designed to reward participants for exceeding the Company’s budgeted operating results by emphasizing the achievement of EPS and return on invested capital targets, and the attainment of several key operating goals shared with all employees. The ranges and targets set each year vary from prior years, in some cases with higher ranges and targets and in some cases with lower ranges and targets. In each case, the OECC sets the ranges and targets taking into account Management’s annual objectives and the way in which those annual objectives fit within the larger growth goals for the Company.

The corporate performance factor is determined using the following formula:

Performance Factor

Earnings Per Share factor. The OECC concluded that EPS would be accorded a weight of 33.33 percent to align executives’ interests with shareholders’ interests and in recognition of the importance earnings have in influencing our future stock price. For 2010, the EPS performance goal consisted of a range of diluted EPS results from $2.508 per share to $2.84 or above, corresponding to payout factors ranging from 0 percent to 150 percent. The target level of diluted EPS was $2.65 per share, corresponding to a 100 percent payout factor. Actual EPS results are interpolated to determine the corresponding performance factor, up to a maximum of 150 percent.

Actual 2010 diluted EPS was $2.73, or 8 cents above the 2010 target of $2.65, resulting in an EPS factor equal to 121.04 percent, which was calculated according to the formula established by the OECC at the beginning of the year.

Return on Invested Capital factor. The weighting assigned to the Return on Invested Capital factor also was 33.33 percent. The OECC includes this measure because there is a significant amount of capital deployed to build and maintain the gas distribution and storage businesses and the OECC wants to hold the executives accountable for ensuring that the Company is getting a reasonable return on the capital being deployed into the business. Return on Invested Capital is defined as net income plus net interest divided by average long-term capital (shareholders’ equity plus long-term debt, including current portion).

This goal consisted of a range of results from 7.21 percent to 8.08 percent or greater, which were generated taking into account NW Natural’s forecasted capital spending plans, corresponding to payout factors ranging from 0 to 150 percent. The target level of return on invested capital was set at 7.95 percent, which corresponds to a 100 percent payout factor, and which is slightly below NW Natural’s current cost of capital.

Actual 2010 return on invested capital was 8.32 percent, resulting in a return on invested capital factor equal to 150 percent.

Key Goals factor. Operating goals of significant importance to the enhancement of our overall profitability and productivity were selected by the OECC to comprise the Key Goals factor, which accounts for 33.33 percent of the weighting for corporate performance goals. The operating goals are substantially aligned with the Key Goals incentive program for all employees. While each goal can contribute a goal rating between 0 and 200 percent multiplied by the assigned goal weight based on actual results, the aggregate of the Key Goals factor is limited to a maximum of 150 percent. Actual results are interpolated to determine the performance factor for each goal.

The Key Goals factor was determined using the following formula:

Sum of [Goal Performance X Goal Weight] for each of 9 Key Goals = Key Goals Factor

A summary of the key operating goals for 2010 and the weighting of each goal to the overall factor is set forth in the following table:


Key Goals	Goal Description	Goal Performance Range	Target (100%) Performance	Goal Weight in Key Goal Performance Factor



Profitability—Earnings per share (utility only)	Earnings per share for utility operations (excludes earnings per share contributions from certain non-utility activities)	$2.49 – $2.75	$2.62	40.00%

Customer satisfaction— overall	On a survey scale of 1-10 (10 as highest), percent of customers rating overall satisfaction at a 9 or 10	56.63% – 63.38%	60.00%	5.00%

Customer satisfaction— employee interaction	Customers who had interactions with service technicians and/or construction crew members rating satisfaction at a 9 or 10	73.75% – 84.25%	79.00%	10.00%

Total Customer Additions	Total new meter sets	8,214 – 10,614	9,414	5.00%

Productivity— expense per customer	Operations and maintainance expense divided by year-end number of customers	$174.88 – $166.38	$170.63	10.00%

Effectiveness of capital investment—capital expenditures per customer	Measures capital expenditures (excluding new meter construction costs) per customer	$125.39 – $116.89	$121.14	5.00%

Effectiveness of Capital Investment—Total Acquisition construction cost per meter	Efficiency measure to calculate construction costs to install each new meter	$2,305.22 – $2,005.22	$2,155.22	5.00%

Retail Gross Margins	Utility net operating revenues	$334,235,000 – $339,965,000	$337,100,000	10.00%

Return on invested capital	Net income plus net interest divided by average long-term capital (shareholders’ equity plus long-term debt, including current portion)	7.21% – 8.21%	7.95%	10.00%

Our operating performance in 2010 resulted in a Key Goals factor at the 150 percent maximum level. Before application of the 150 percent cap on this factor, our performance relative to the Key Goals generated a payout factor of 163 percent. This high level of achievement resulted from several operating goals for which target levels were substantially exceeded (e.g., the utility EPS, return on invested capital, productivity—expense per customer, and overall customer satisfaction goals were each equal to the maximum of 200 percent, the employee interaction customer satisfaction goal was equal to 188 percent, and the retail gross margin goal was equal to 144 percent). High performance on these goals more than offset those goals that were achieved below targeted levels (e.g., the total customer additions goal was equal to 5 percent), or not achieved at all (e.g., capital expenditures per customer and total acquisition construction cost per meter were equal to 0 percent). The goals not achieved were primarily due to a slowdown in the new construction market as a result of the national economic recession and housing market decline, and higher than planned costs for new customer additions.

For 2010, the combination of the Earnings Per Share factor, the Return on Invested Capital factor and the Key Goals factor, produced an overall corporate performance factor equal to 140.35 percent of target.

Individual Performance Goals. Twenty-five percent of each Named Executive Officer’s annual incentive target award is based on individual performance goals. In the case of the Chief Executive Officer, individual goals are determined by the OECC in consultation with the Chief Executive Officer. The Chief Executive Officer’s attainment of his goals is determined largely based on the OECC’s qualitative assessment of the Chief Executive Officer’s performance. The other Named Executive Officers’ individual performance goals align with the Chief Executive Officer’s goals and support the Company’s strategic plan. The OECC and the Company believe that achieving its strategic goals, along with the strong operation and management of our day-to-day business, will create success for our customers, employees and shareholders. Generally, NW Natural’s 2010 annual priority goals included:

improving productivity through the continued deployment and integration of new technology and through the effective use of resources;

continuing advancement of the Palomar projects;

completing construction of Gill Ranch consistent with milestone objectives;

continuing to emphasize NW Natural’s commitment to clean and green policies and technologies;

achieving overall customer satisfaction consistent with the Key Goals target;

achieving EPS growth, return on invested capital and cash flow targets; and

accomplishing these goals in a manner consistent with NW Natural’s core values.

In addition to the above shared executive officer goals, the Chief Executive Officer’s individual performance goals included exceeding the EPS goal, ensuring that the construction of Gill Ranch was completed and certain capacity contracts received by year end, advancement of Palomar and the continued strengthening of alignment and strategic direction of the executive management team.

The Chief Executive Officer evaluated the 2010 individual performance of each Named Executive Officer on a scale from 0 to 150 percent, based on performance and peer ratings. The Chief Executive Officer’s recommendations regarding individual performance are reviewed and approved by the OECC as it reviews the overall performance of executives against the operating goals. The OECC uses this same method of assessment to establish the year-end performance rating for the Chief Executive Officer. The OECC determined that executives had met or exceeded these goals and assigned a rating of 114 percent for the Chief Executive Officer’s individual performance. Performance of the other Named Executive Officers ranged from 77.78 percent to 127.74 percent.

On average, the total awards for the Chief Executive Officer and the other Named Executive Officers were 32.66 percent above the target awards for the year, primarily due to higher than targeted EPS and return on invested capital performance for the year.

Long-Term Incentives

The long-term incentive portion of our executive compensation program consists of two components: stock options and performance shares. The Consultant provides the OECC with annual compensation survey data based on the total expected value of long-term incentives, which is defined for stock options to be the grant-date Black-Scholes value of options granted

during the year, and is defined for performance share awards to be the grant-date market price of the target number of performance shares covered by awards during the year. The survey data provided by the Consultant in February 2010 showed lower expected values of long-term incentives for all executive positions than the survey data provided in 2009, reflecting generally lower industry equity values in the 2010 survey period. Accordingly, for all Named Executive Officers other than Ms. Kirkpatrick, the 2010 survey data indicated that the expected value of long-term incentives granted in 2009 was above the energy service median levels for their positions. As the only executive below market, Ms. Kirkpatrick therefore received a higher performance share grant in 2010 compared to 2009 to bring her long-term incentive value up to the energy service median level for her position. The OECC chose not to reduce grant levels based on the 2010 survey data, so the stock option and performance share award levels Mr. Anderson, Ms. Doolittle and Mr. White were unchanged in 2010. For Mr. Kantor, the OECC’s compensation strategy is to award target long-term incentive opportunities above market for his position while maintaining salary below market for his position to tie a relatively larger percentage of his compensation directly to long-term Company performance. Accordingly, the targeted value of long-term incentives granted to Mr. Kantor in 2010 increased by 27 percent compared to 2009, to a level that was 137 percent of the energy service median level for his position in the 2010 survey data, although only 114 percent of the energy service median level for his position in the 2009 survey data.

In 2010, the long-term incentive portion of our executive compensation program was designed such that approximately 20 percent of the expected value of long-term incentives to be granted to each Named Executive Officer’s interest would be granted in the form of stock options, and approximately 80 percent of such expected value of long-term incentives would be granted as performance share awards. While equity provides incentives to executives to work toward increasing the price of our Common Stock, and to more closely align executives’ interests with shareholders’ interest, the performance share program rewards relative stock price performance to a peer group, and also focuses the executives on key long-term objectives that align with the creation of shareholder value, thereby tying this portion of executive pay to Company performance. The OECC believes that equity provides a balanced performance focus for executives.

For 2010 compensation, the expected value of long-term incentives represented approximately 52 percent of the target total direct compensation for the Chief Executive Officer and approximately 32 percent on average for the other Named Executive Officers.

Stock Options

In 2010, pursuant to the Restated Stock Option Plan, the OECC granted stock options which vest equally over four years. Except in cases of grants of options made to attract new employees, option and performance share grants are made by the OECC at its meeting each February. This is the same time the OECC considers and approves changes in all of the other components of executive compensation, thus having the benefit of considering the relative value of all components of pay (base salary, and annual and long-term incentives) at once, as well as reviewing the Consultant’s annual updated competitive compensation analysis. The exercise price for stock options is set at 100 percent of the closing market price of our Common Stock quoted on the NYSE on the date of grant. The OECC uses the same practice to establish stock option exercise prices for all employees receiving options. Option repricing is specifically prohibited under our Corporate Governance Standards.

It is the OECC’s policy to grant non-statutory stock options under the Internal Revenue Code and the related regulations so that any compensation recognized upon the exercise of options will be tax deductible by NW Natural. The shareholders have previously approved the

Restated Stock Option Plan to comply with the performance-based compensation requirements of Section 162(m) of the Internal Revenue Code, and the plan provisions are designed to satisfy the other requirements for performance-based compensation so that compensation related to the exercise of options granted under this Plan would not be subject to the $1 million limitation on tax-deductible compensation.

In 2010, the Company amended its form of stock option agreement, effective for both new and existing options, to generally provide that if a participant’s misconduct contributes to an inflated stock price and the participant sells shares acquired upon exercise of an option at such inflated stock price, the OECC may require the participant to repay the amount determined by the OECC to be the excess amount received. Additionally, these agreements were amended to preclude any exercise of options following termination of employment by any participant who is terminated for cause.

Among the factors the OECC considers in determining the number of options to be granted to the Chief Executive Officer, and that the Chief Executive Officer considers when making recommendations for the other Named Executive Officers, are:

•

the total long-term competitive market compensation survey data provided by the Consultant;

•

the executive’s relative position and level of responsibility within NW Natural;

•

the performance of the executive during the prior period;

•

the retention value of options before vesting; and

•

the number of options needed to ensure that executives are focused on absolute share price appreciation over the long term.

Considering these factors, the OECC granted options to the Named Executive Officers in 2010 as shown in the “Grants of Plan-Based Awards During 2010” table below. The option grant for Mr. Kantor in 2010 increased by 5,000 shares compared to his 2009 option grant of 25,000 shares, due to the OECC’s desire to have a greater portion of Mr. Kantor’s total mix of compensation be at-risk and contain a greater weighting of long-term incentive to incent him to focus on long-term Company performance. Option grants in 2010 for Mr. Anderson, Ms. Doolittle, Mr. White and Ms. Kirkpatrick remained unchanged from 2009 at 8,000, 3,000, 4,000 and 4,000, respectively.

Performance Shares

The second component of our executives’ long-term compensation program is provided through a performance share program under our Long Term Incentive Plan. The purpose of the performance share program is to provide a means for rewarding executives for their success in driving long-term performance results that increase shareholder value and to tie executive compensation directly to Company performance. This component is also designed to encourage ownership of our stock by our executives. All of the Named Executive Officers participate in the performance share program.

In 2010, the Company amended the form of performance share agreement for new awards to generally provide that if a participant’s misconduct contributed to an inflated payout under the total shareholder return component of any award because the Company’s stock price in the last three months of the performance cycle was higher than it would have been absent the misconduct, the OECC may require the participant to repay the amount determined by the OECC to be the excess amount received.

In February 2010, each Named Executive Officer received a performance share award to be earned over a three-year performance period (2010-2012). The threshold (minimum award other than no award), target and maximum performance share awards approved by the OECC for the Named Executive Officers in 2010 were primarily based on the Consultant’s analysis considering competitive opportunities for comparable executive positions and consideration of the level of expected value provided by the program as a percentage of the participant’s total direct compensation opportunity. In 2010, Mr. Kantor’s performance share award increased by 2,000 shares, from 13,000 shares in 2009 to 15,000 shares in 2010 due to the OECC’s desire to have a greater portion of Mr. Kantor’s total mix of compensation be at-risk and contain a greater weighting of long-term incentives to incent him to focus on long-term Company performance. Ms. Kirkpatrick’s performance share award increased by 500 shares, from 3,000 shares in 2009 to 3,500 shares in 2010 to better align her incentive compensation with competitive market medians. Performance share awards remained the same for Mr. Anderson, Ms. Doolittle and Mr. White in 2010 at 5,500, 2,500 and 3,000, respectively.

The performance criteria used for the three most recent three-year performance cycles, 2008-2010, 2009-2011 and 2010-2012, were based on two primary factors: a total shareholder return component that measures relative total shareholder return versus a named peer group of energy companies (weighted 75 percent of the total award) and a strategic component which measures achievement of performance milestones relative to our core and non-core strategic plan goals (weighted 25 percent of the total award).

Total Shareholder Return Component. 75 percent of the performance share award is based on total shareholder return relative to a peer group of 10 natural gas utility companies. The OECC selected this peer group of companies because of the companies’ comparability to NW Natural both in terms of size and the nature of their business. This peer group differs from the group included in the total shareholder return table appearing in our 2010 Annual Report to Shareholders in that it focuses on local gas distribution companies instead of a broader group of energy companies. This peer group consists of AGL Resources Inc., Atmos Energy Corporation, South Jersey Industries, Inc., The Laclede Group, Inc., New Jersey Resources Corporation, Nicor Inc., Vectren Corporation, Piedmont Natural Gas Company Inc., Southwest Gas Corporation and WGL Holdings, Inc. This peer group is also considered by the OECC when reviewing compensation practices but is not the primary source of comparison used. Some or all of the companies may be included in the total shareholder return table included in our 2010 Annual Report. If over the course of the cycle a peer company ceases to be publicly traded, an alternative peer company is substituted from a pre-established alternate peer list, which for the 2010-2012 cycle consists of NiSource, National Fuel Gas Company and Chesapeake Utilities Corporation. Total shareholder return is the return a shareholder earns over a specified period of time, in this case the three-year performance period. Total shareholder return measures the change in share price, assuming dividends are reinvested, and is what we might expect a shareholder to receive from his or her ownership in NW Natural. The value at the end of the period is determined based on the three-month average daily closing price prior to the end of the performance period compared to the three months immediately prior to the start of the performance period. This measure was determined by the OECC to best align the interests of management with those of the shareholders. For performance cycles prior to the 2010-2012 cycle, we are required to achieve a minimum average of six percent total shareholder return per year (a cumulative total of 19.1 percent for the three-year cycle) over the three-year period before any awards can be earned under this component. In 2010, the OECC reviewed the minimum average total shareholder return requirement by looking at peer companies’ thresholds and past plan payouts. The OECC determined that peer companies’ plans did not contain a similar threshold. The OECC also determined that the minimum threshold prevented appropriate performance share payouts in

years where the Company had overall outstanding relative performance. As a result, for the 2010-2012 cycle, the OECC reduced the minimum average total shareholder return requirement to 0 percent, so that for the 2010-2012 cycle and on a go-forward basis, this component will pay out based on performance relative to the peer group so long as the Company’s total shareholder return is a positive number for the cycle.

The following table shows the total shareholder return component factors we use to determine NW Natural’s factor for total shareholder return compared to rankings for companies in the peer group noted above:


Total Shareholder Return Ranking for Peer Group		Total Shareholder Return Component Factor
10		0%
9		0%
8		25%
7		25%
6		50%
5		75%
4		100%
3		125%
2		150%
1		200%

For the 2008-2010 performance cycle, NW Natural’s total shareholder return was a cumulative 12.63 percent, which was below the level achieved by the ninth best performing company in the peer group, and therefore resulted in a 0 percent payout factor for the total shareholder return component. As indicated above, the total shareholder return is, in part, based on the difference between the three-month average daily closing price prior to the end of the performance period compared to the three month average immediately prior to the start of the performance period. The total shareholder return on this calculation was lower for NW Natural than its peers due in part to NW Natural’s strong comparative performance in the cycle that ended with the last three months of 2007, which set a higher floor against which the current period’s stock price performance was measured.

Strategic Component. The remaining 25 percent of any performance share award is subjective and determined at the discretion of the OECC at the end of the three-year performance cycle. Among other things, the OECC considers actual performance relative to strategic milestones set forth in our strategic plan and approved by the OECC prior to the beginning of the cycle. Factors considered by the OECC include, but are not limited to:

financial measures, consisting of return on invested capital and return on equity;

growth measures relating to organizational transition, gas storage and pipeline and gas supply projects; and

leadership development and succession planning matters.

The following formula is used to determine the performance share factor at the end of the three-year performance period. This factor is then applied to the target awards for each award recipient.

At the end of the 2008-2010 program term, the OECC determined the degree to which the strategic goals were achieved. The OECC weighed its subjective assessment of strong NW Natural financial performance, management’s business development activities, milestones achieved in execution of our strategic plan in workforce development and succession planning, management’s strong performance in executing its business plan cost effectively in a low-growth economy, and management’s continued progress toward its overall goal of achieving NW Natural’s five percent annual long-term earnings growth targets, as well as challenges in the construction and start-up of our Gill Ranch gas storage project, including some budget overruns and the difficult gas storage market generally, and assigned a strategic component factor of 95.75 percent, which was slightly below expected targets.

Because the OECC’s determination as to the achievement of this portion of the award is discretionary, amounts paid to the Named Executive Officers may not be tax deductible under Section 162(m) of the Internal Revenue Code. See “Regulatory, Tax and Accounting Considerations,” below.

Total 2010 Performance Shares. The combination of the total shareholder return component factor (at 0 percent, weighted 75 percent) and the strategic component factor (at 95.75 percent, weighted 25 percent) for the 2008-2010 cycle resulted in a performance share factor of 23.94 percent of target. For actual 2010 award amounts, see the “Option Exercises and Stock Vested During 2010” table, below.

Storage Project Performance Share Award. Mr. White is the executive officer with principal responsibility for the development of the Company’s Gill Ranch gas storage project. To provide an additional incentive for Mr. White specifically related to the successful completion and early performance of this multi-year project, in February 2009 the OECC approved a special performance share award to him for 2,000 shares. The performance goals for this award are subjective and will be determined in the discretion of the OECC, with one-half of the target award subject to project completion and initial performance through June 30, 2011, and one quarter of the target award subject to performance of the project in each of the following 12-month periods. Payout of this award can range from 0 percent to 125 percent of the target award.

Perquisites

The OECC reviewed its perquisite policy and eliminated perquisites for executives effective January 1, 2008. The OECC acknowledges that certain benefits incidental to other business-related activities may continue, but the aggregate annual value of such benefits is not expected to exceed $10,000 for any Named Executive Officer. The OECC confirmed that while many utilities continue to provide some level of perquisites, many general industry companies are moving away from this practice as these benefits are not provided to all employees.

Qualified and Non-Qualified Retirement (Defined Benefit) Plans

In general, when compared to non-utilities, the utility industry has historically provided a greater percentage of total remuneration in the form of retirement benefits, particularly in the form of defined benefit plans, rather than current cash compensation. The Named Executive Officers participate in the Retirement Plan for Non-Bargaining Unit Employees, our qualified defined benefit pension plan, on the same terms as other salaried employees. We also maintain the following non-qualified supplemental retirement plans for certain executives: the Executive Supplemental Retirement Income Plan and the Supplemental Executive Retirement Plan. These plans are more fully described below under the “Pension Benefits as of

December 31, 2010” table and the related narrative discussion. As discussed there, in 2009 the OECC recommended and the Board approved amendments to these plans that will moderate the growth in benefits payable under these plans.

Qualified and Non-Qualified Deferred Compensation (Defined Contribution) Plans

We also maintain both tax-qualified and non-tax-qualified defined contribution plans in which the Named Executive Officers are eligible to participate. Our 401(k) Plan is a tax-qualified defined contribution plan and our Deferred Compensation Plan for Directors and Executives is a non-tax-qualified deferred compensation plan. For further discussion of Named Executive Officer participation in non-qualified deferred compensation plans in 2010, see the “Non-Qualified Deferred Compensation in 2010” table below.

Change in Control/ Severance Agreements

The Board of Directors considers the establishment and maintenance of an effective, sound and vital management team to be essential to protecting and enhancing the best interests of our Company. In recognition of the possibility of a change in control of NW Natural and that such possibility, and the uncertainty and questions that it could raise among management, may result in the departure or distraction of management personnel to our detriment, the Board has approved double trigger severance agreements with all of the Named Executive Officers. The agreements contain a provision that reduces the level of benefits available under the agreements as the Named Executive Officers approach age 65 given that the value of the benefit should diminish commensurate with an officer’s potential remaining years of employment. The Board believes the current form of severance agreement reflects a conservative approach using energy industry standards. None of the agreements with officers of NW Natural include provisions for tax gross-up upon a triggering event. See “Potential Payments Upon Termination or Change in Control,” below.

In general, the OECC prefers not to enter into severance agreements other than for change in control purposes as discussed above. Accordingly, the OECC has established a guideline that severance benefits may only be provided following a termination without cause in the first five years of employment in a particular position or after a change in control. The benefit for termination without cause, absent a change in control, is reduced over the term of the agreement, which cannot exceed five years. In late 2008, the OECC approved an agreement of this nature with Mr. Kantor as the incoming Chief Executive Officer. See “Potential Payments Upon Termination or Change in Control,” below.

Regulatory, Tax and Accounting Considerations

Regulatory Treatment

We fully assess the accounting and tax treatment of each form of compensation paid to the Named Executive Officers for both NW Natural and the individual executive. This is particularly important in a regulated business where we are allowed to recover costs of service in rates (salaries, qualified pensions and health and welfare benefit costs), while other elements of executive compensation, such as annual incentive awards, long-term performance shares and non-qualified retirement benefits, are typically shareholder expenses because the programs are designed to meet shareholder objectives. However, our incentive compensation programs benefit customers by including performance incentives that:

•

encourage efficient, safe and reliable service;

•

encourage management of capital, operating and maintenance costs, which helps to abate the need for future rate increases; and

•

focus on customer satisfaction.

See “Corporate Performance Goals,” above. Actual amounts currently recovered in rates are based on amounts determined in our general rate cases approved by the Oregon Public Utility Commission in 2003 and by the Washington Utilities and Transportation Commission in 2008. The following table shows the current rate recovery treatment for categories of compensation expenses for various elements of our executive compensation program:


Expenses Recovered in Rates		Expenses Not Recovered in Rates

Salaries		Stock Options

Qualified pension plan benefits		Executive Annual Incentive Plan

Qualified Retirement K Savings Plan matching contributions Health and welfare benefits		Long Term Incentive Plan Interest accruals and matching contributions on Deferred Compensation Plan for Directors and Executives

		Interest accruals on Executive Deferred Compensation Plan

		Executive Supplemental Retirement Income Plan

		Supplemental Executive Retirement Plan

		Change-in-control severance benefits

		Non-change-in-control severance benefits

Tax Deductibility of Compensation

In developing executive compensation programs, the OECC takes into consideration the tax deductibility of the various components of compensation under the Internal Revenue Code. Section 162(m) of the Internal Revenue Code generally limits to $1 million per person the amount that may be deducted for compensation paid in any year to our Named Executive Officers (other than the chief financial officer). Certain exceptions to this limitation apply to “performance-based compensation.” We have obtained shareholder approval of the Restated Stock Option Plan and the Long Term Incentive Plan to qualify the exercise of non-statutory stock options and the payment of the non-discretionary portion of long-term incentive awards under the Long Term Incentive Plan as performance-based so that compensation received would not be subject to the $1 million limitation. It is the OECC’s policy to grant options that meet the requirements of the Internal Revenue Code and related regulations so that any such compensation recognized by an optionee will be fully-deductible, performance-based compensation. The non-discretionary portion of performance share long-term incentive awards granted by the OECC is also generally intended to meet the “performance-based compensation” requirements of the Internal Revenue Code and related regulations so that any compensation paid under the non-discretionary portion of those awards should be fully deductible. We do not expect any amounts paid to our Named Executive Officers in 2010 to be considered non-deductible under Section 162(m).

SUMMARY COMPENSATION TABLE

The following is a summary of the compensation for our Named Executive Officers in 2008, 2009 and 2010. Only a portion of the executive compensation shown in this Summary Compensation Table is included for purposes of establishing regulatory rates charged to customers. Although most of our compensation programs are designed to promote shareholder objectives, our customers also directly benefit because many of the programs include performance incentives that are designed to improve service to our customers. For discussion regarding amounts excluded from rate recovery, see “Compensation Discussion and Analysis—Regulatory, Tax and Accounting Considerations—Regulatory Treatment,” above.

The total bonus paid to each Named Executive Officer under our Executive Annual Incentive Plan for performance in 2010 is split between columns (d) and (g). Amounts constituting the discretionary portion of bonuses under the plan are the amounts listed as bonuses in column (d). Amounts constituting the performance-based, non-discretionary portion of bonuses under the plan are the amounts listed as non-equity incentive plan compensation in column (g).

Amounts shown in column (e) represent the grant date fair value of performance share awards granted in each year, disregarding estimated forfeitures, determined under share-based compensation accounting guidance. The issuance of the shares under these awards is contingent upon meeting certain performance criteria, so the shares may or may not be earned. The portion of each performance share award based on relative total shareholder return (75 percent of each target award other than Mr. White’s 2009 gas storage project award) is considered to be subject to a market condition, so the amount shown for that portion of each award represents the grant date fair value of the award calculated using a binomial pricing model. For the remaining portion of each performance share award subject to strategic performance milestones (100 percent of Mr. White’s 2009 gas storage project award and 25 percent of each other target award), the amount shown is based on the estimated number of shares to be issued multiplied by the sum of the closing market price of the Common Stock on the date of grant plus the estimated dividends per share to be paid over the three-year performance period. As of the grant date of these awards, the target number of shares was estimated to be the number of shares to be issued under the strategic portions of the awards. If the maximum number of shares issuable under the strategic portion had been used as the estimated number of shares, the total amounts in column (e) for 2010 would have been $570,366 for Mr. Kantor, $209,134 for Mr. Anderson, $95,061 for Ms. Doolittle, $114,073 for Mr. White, and $133,085 for Ms. Kirkpatrick.

Amounts shown in column (f) represent the grant date fair value of options granted in each year, disregarding estimated forfeitures, estimated using the Black-Scholes option pricing model. The assumptions used in determining the grant date fair values of options under share-based compensation accounting guidance are disclosed in Note 6 to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2010.

⁴

The amounts included in column (h) as the aggregate change in the actuarial present value of the Named Executive Officers’ accumulated benefits under all defined benefit pension plans during 2010 were: $1,291,313 for Mr. Kantor, $185,864 for Mr. Anderson, $398,033 for Ms. Doolittle, $258,338 for Mr. White, and $148,589 for Ms. Kirkpatrick. Amounts of above-market interest included in column (h) that were credited to the non-qualified deferred compensation plan accounts of the Named Executive Officers during 2010 were: $4,695 for Mr. Kantor, $73 for Mr. Anderson, $4,335 for Ms. Doolittle, $4,683 for Mr. White, and $0 for Ms. Kirkpatrick. For this purpose, interest credited is considered above-market to the extent such interest exceeds 120 percent of the average of the applicable long-term federal rates, with quarterly compounding, for the three months in the prior quarter.

⁵

The amounts included in column (i) as matching contributions under the qualified defined contribution plan 401(k) Plan during 2010 were: $8,820 for each of Mr. Kantor, Mr. Anderson, Ms. Doolittle, Mr. White and Ms. Kirkpatrick. The amounts paid as matching contributions under non-qualified deferred compensation plans during 2010 were: $23,377 for Mr. Kantor, $11,589 for Mr. Anderson, $4,268 for Ms. Doolittle, $0 for Mr. White, and $0 for Ms. Kirkpatrick. Amounts in column (i) also include a $250 gift card plus $164.25 gross up expense for each of Mr. Anderson, Ms. Doolittle, Mr. White and Ms. Kirkpatrick.

Executive Officer Perquisites

We do not routinely provide perquisites to our executive officers. No Named Executive Officer received perquisites totaling $10,000 or more in 2010.

GRANTS OF PLAN-BASED AWARDS DURING 2010

Column (i) was deleted as it is not applicable.

Threshold level estimated payouts cannot be determined because the minimum performance level for payout under each component of the formula in the Executive Annual Incentive Plan is interpolated down to a zero payout. See “Executive Annual Incentive Plan Awards” following this table and “Compensation Discussion and Analysis—Compensation Programs—Executive Annual Incentive Plan,” above, for a complete discussion of the terms of the awards. Amounts above include only the portion of the award subject to performance metrics, constituting 75 percent of the annual incentive opportunity. The remaining 25 percent of the annual incentive opportunity is awarded based on discretionary criteria and is reflected as a bonus in column (d) of the Summary Compensation Table. The actual non-equity incentive plan portion of the awards earned in 2010 and paid in 2011 are reflected in column (g) of the Summary Compensation Table.

Share amounts represent potential performance share awards granted pursuant to the terms of the Long Term Incentive Plan (LTIP). See “Long Term Incentive Plan Awards” following this table and “Compensation Discussion and Analysis—Compensation Programs—Long-Term Incentives—Performance Shares,” above, for a complete discussion of the terms of the awards. Share amounts do not include an estimate of an additional $5.28 per share dividend equivalent also payable pursuant to the terms of the awards. Threshold level estimated future payouts assume the minimum award payable other than no payout for each component of the formula in the LTIP.

Stock options granted on February 24, 2010 pursuant to the Restated Stock Option Plan vest in four equal installments on February 24, 2011 and January 1, 2012, 2013 and 2014. Vesting will be accelerated upon death, disability or retirement as described below under “Potential Payments upon Termination or Change in Control.” Each option has a maximum term of 10 years and seven days, subject to earlier termination in connection with a termination of the optionee’s employment.

⁴

Amounts shown in column (l) for option awards represent the grant date fair value of the options based on a value of $6.36 per share calculated using a Black-Scholes option pricing model. The portion of each performance share award under the LTIP based on relative total shareholder return (75 percent of each target award) is considered to be subject to a market condition under share-based compensation accounting guidance, so the amounts shown for that portion represent the grant date fair value of the awards based on a value of $17.68 per share calculated using a binomial pricing model. Amounts shown for the remaining portion of each performance share award subject to strategic performance milestones (25 percent of each target award) represent the grant date fair value of the awards based on a value of $49.53 per share which was the sum of the closing market price of the Common Stock on the grant date plus the estimated dividends per share to be paid over the three-year performance period. The values used for option and performance share awards are the same as those used under share-based compensation accounting guidance. The assumptions used in determining option values are described in Note 6 to the Consolidated Financial Statements in our Annual Report on Form 10-K for the year ended December 31, 2010.

Compensation and Award Table Discussion

Executive Annual Incentive Plan Awards

Payment of awards under the Executive Annual Incentive Plan is contingent upon meeting predetermined individual and corporate performance goals. Depending upon position, performance, and the other factors considered by the Organization and Executive Compensation Committee (OECC), the Named Executive Officers may earn from 35 percent to 70 percent of base salary if the prescribed corporate and individual performance goals are met, or up to 52.5 percent to 105 percent of base salary if these goals are exceeded. At the beginning of each year, weighted performance goals are established and, at year-end, performance is measured against these goals. Actual results are considered by the OECC in determining the amounts to be awarded, if any. For further discussion regarding the Executive Annual Incentive Plan, including the components of corporate and individual performance, see “Compensation Discussion and Analysis—Compensation Programs—Executive Annual Incentive Plan,” above.

Long Term Incentive Plan Awards

The OECC makes annual performance share awards under the Long Term Incentive Plan payable in Common Stock based on our performance over three-year performance cycles. Target awards are determined by the OECC for each participant. Executives are limited to a maximum performance share award equal to 200 percent of the target award.

The OECC establishes corporate performance measures based on total shareholder return relative to our peer group, with a minimum required average return over the performance period of six percent per year for the cycle (75 percent of award) and performance milestones relative to our core and non-core strategic plans (25 percent of award). At the end of the cycle, the OECC determines whether the strategic performance milestones were achieved and assigns a factor ranging between 0 percent and 200 percent. As a general guideline, if we achieve the targets as stated, each component factor would be 100 percent. A participant generally must be employed by NW Natural at the end of the performance period to receive an award payout, although pro-rated awards will be paid if employment terminates earlier on account of death, disability or retirement. Awards will be paid in Common Stock as soon as practicable after the end of the performance period. Participants will also receive dividend equivalent cash payments on the number of shares of Common Stock received on the award payout multiplied by the aggregate cash dividends paid per share by NW Natural during the performance period. For further discussion regarding the terms of the performance shares, see “Compensation Discussion and Analysis—Compensation Programs—Long-Term Incentives—Performance Shares,” above.

Restricted Stock Grants. The Long Term Incentive Plan also provides the OECC the ability to grant restricted stock awards. Typically, restricted stock awards are used in special, limited circumstances such as new hire grants and retention or special recognition awards. The OECC infrequently makes restricted stock grants since our long-term incentive program is heavily-weighted to performance shares under the Long Term Incentive Plan, which provides stock incentives that are linked to performance. No restricted stock grants were made during 2010, and as of December 31, 2010, no restricted stock awards were outstanding.

¹	Amounts are calculated based on the price of $46.47, the closing market price on the NYSE on December 31, 2010.

All share amounts are based on target level awards of performance shares eligible to be earned under the Long Term Incentive Plan (LTIP) upon achievement of performance objectives, which is determined to be the most probable level of payout other than no award. The actual number of shares issuable will be determined by the OECC at the end of the three-year performance cycles ending December 31, 2011 and 2012. Amount does not include an estimate for the accumulated cash dividends also

payable pursuant to the terms of the awards. For a complete description of the performance objectives, see “Compensation Discussion and Analysis—Compensation Programs—Long-Term Incentives,” above.

Amounts represent performance share awards earned by the Named Executive Officers for the three-year award cycle 2008-2010 under the Long Term Incentive Plan (LTIP), but unpaid as of the fiscal year-end and are based on a price of $46.47, the closing market price on the NYSE on December 31, 2010, plus dividend equivalents. The award paid at 24 percent of the target level incentive based upon total shareholder return performance and strategic results. See “Compensation Discussion and Analysis—Compensation Programs—Long-Term Incentives—Performance Shares,” above. The number of shares actually paid was determined by the OECC on February 23, 2011. Value realized includes cash for dividend equivalents of $4.80 per share based on dividends per share paid by us during the performance period as follows: Kantor, $7,469; Anderson, $6,322; Doolittle, $4,022; White, $3,446; and Kirkpatrick, $3,446. Receipt of the following amounts under performance share awards was deferred pursuant to elections under our Deferred Compensation Plan for Directors and Executives: Mr. Kantor, 389 shares valued at $18,077 and $1,867 of dividend equivalents; Mr. Anderson, 0 shares; Ms. Doolittle, 126 shares valued at $5,855 and $0 of dividend equivalents; Mr. White, 718 shares valued at $33,365 and $0 of dividend equivalents; and Ms. Kirkpatrick, 0 shares.

The Present Value of Accumulated Benefit in the above table represents the actuarial present value as of December 31, 2010 of the pension benefits of the Named Executive Officers under the respective pension plans calculated based on years of service and final average compensation as of that date but assuming retirement at the earliest age at which benefits were unreduced under the respective plans. Mr. Kantor’s years of service under the Executive Supplemental Retirement Income Plan are based on his years of service since becoming eligible to participate under the plan. The actuarial present value was calculated assuming all participants are fully vested, and using the 2011 Static Mortality Table for Non-Annuitants per § 1.430(h)(3)-1(e) and a discount rate of 5.61 percent, the same assumptions used in the pension benefit calculations reflected in our audited balance sheet as of December 31, 2010.

Ms. Doolittle is eligible for early retirement benefits under the Executive Supplemental Retirement Income Plan (ESRIP), but not the other pension plans in which she is a participant. If she had retired on December 31, 2010 and immediately commenced receiving an early retirement benefit under the ESRIP, the Present Value of Accumulated Benefits under the ESRIP for her as reflected in the above table would have been higher by $9,558.

Mr. White is eligible for early retirement benefits under the pension plans in which he is a participant. If he had retired on December 31, 2010 and immediately commenced receiving an early retirement benefit under those plans, the Present Value of Accumulated Benefits for him as reflected in the above table would have been higher by the following amounts: Retirement Plan for Non-Bargaining Unit Employees—$53,172, Supplemental Executive Retirement Plan Tier 2—$8,975, and Deferred Compensation Plan Supplemental Annuity—$3,823.

Retirement Plan for Non-Bargaining Unit Employees

The Retirement Plan for Non-Bargaining Unit Employees (NBU Plan) is our qualified pension plan covering all regular, full-time employees not covered under a labor agreement whose employment commenced prior to January 1, 2007 (when the NBU Plan was closed to new participants). Eligible employees commenced participation in the NBU Plan after one year of service and become 100 percent vested after five years of service. Final average earnings for purposes of calculating benefits consist of the participant’s highest average total annual compensation for any five consecutive years in the last ten years of employment, with total annual compensation for this purpose generally consisting of salary and annual incentive, excluding long-term incentives, amounts deferred under our non-qualified deferred compensation plans and, commencing in 2010 as provided in an NBU Plan amendment approved in 2009, annual incentive payments in excess of target. In addition, as of December 31, 2010, the Internal Revenue Code limited the amount of annual compensation considered for purposes of calculating benefits under the NBU Plan to $245,000.

A normal retirement benefit is payable upon retirement at or after age 62 and consists of (a) an annuity benefit equal to 1.8 percent of final average earnings for each of the participant’s first 10 years of service, and (b) a lump sum benefit equal to 7.5 percent of final average earnings for each year of service in excess of 10 years. In addition, for participants hired before January 1, 2000 and under age 60 on that date (including Messrs. Kantor and White), a supplemental annuity is provided under the NBU Plan equal to the participant’s total years of service multiplied by the sum of (x) a varying percentage (based on the participant’s hire age and age on January 1, 2000, and which is 0.295 percent for Mr. Kantor and 0.447 percent for Mr. White) of total final average earnings, and (y) 0.425 percent of the excess of final average earnings over an amount referred to as Covered Compensation, which generally consists of the average of the Social Security maximum taxable wage bases over the 35 years preceding the participant’s retirement.

Employees who have attained age 55, if age plus accredited years of service totals 70 or more, are eligible for early retirement benefits. Annuity benefits are reduced by 1/3 percent per month (four percent per year) for each month that the benefit commencement date precedes age 62, with such benefit reduction increased to 1/2 percent per month (six percent per year) for each month that the benefit commencement date precedes age 60. The lump sum benefit is not subject to reduction on early retirement. At December 31, 2010, Mr. White was the only Named Executive Officer eligible for early retirement benefits under the NBU Plan.

The basic benefit form for annuity benefits is a monthly single life annuity. The participant may choose among different annuity forms that are the actuarial equivalent of the basic benefit.

Deferred Compensation Plan Supplemental Annuity

As discussed above, final average earnings for purposes of calculating benefits under the NBU Plan excludes amounts deferred under our non-qualified deferred compensation plans, consisting of our Executive Deferred Compensation Plan (EDCP) and Deferred Compensation Plan for Directors and Executives (DCP), which are described below under “Non-Qualified Deferred Compensation Plans.” Accordingly, deferral of compensation under these plans during a participant’s last 10 years of employment may result in a reduction in benefits payable

under the NBU Plan unless the participant’s total annual compensation in each of those years is over the limit ($245,000 in 2010) imposed by the Internal Revenue Code. In recognition of this possible loss of NBU Plan benefits, the DCP provides for payment of a supplemental annuity generally payable in the same form and for the same period of time as the annuity payable under the NBU Plan, subject to certain requirements for the timing of commencement of benefits. The supplemental annuity is equal to the difference between the actual benefit under the NBU Plan assuming the participant had elected to receive the lump sum benefit in the form of an annuity and the corresponding benefit that otherwise would have been payable under the NBU Plan if the participant had not deferred compensation under the EDCP and/or the DCP.

Executive Supplemental Retirement Income Plan

The Executive Supplemental Retirement Income Plan (ESRIP) is a non-qualified pension plan providing supplemental retirement benefits to persons who were executive officers prior to September 1, 2004, including Mr. Kantor and Ms. Doolittle. Under the ESRIP, a target annual retirement benefit is determined for each participant, which is then reduced by the participant’s (a) NBU Plan benefit (with the lump sum portion converted to a single life annuity), (b) annual Social Security benefits, and (c) any supplemental annuity under the DCP, in each case assuming commencement of benefits at age 65. Final average compensation for purposes of calculating ESRIP benefits generally consists of the participant’s highest average salary and annual incentive for any three consecutive compensation years in the last 10 years of employment. Long-term compensation is excluded from the definition of final average compensation. To help control the cost of future benefits under the ESRIP, the Board authorized ESRIP amendments in 2009 to provide that, commencing with annual incentives paid for 2010 performance, annual incentive compensation in excess of 125 percent of target will also be excluded from the calculation of final average compensation. As provided in the same ESRIP amendments, final average compensation will be calculated using a four-year average commencing on December 31, 2012 for Ms. Doolittle and commencing on December 31, 2013 for Mr. Kantor, increasing to a five-year average for each of them one year later.

The target annual retirement benefit is equal to (a) 4.33 percent of final average compensation for each of the participant’s first 15 years of service, plus (b) for persons who were ESRIP participants as of September 1, 1998 (including Mr. Kantor), 0.5 percent of final average compensation for up to 10 additional years of service in excess of 15 years. This formula results in a target benefit of 65 percent of final average compensation after 15 years of service and a maximum 70 percent of final average compensation for those eligible after 25 years of service. A normal retirement benefit equal to the target benefit reduced by NBU Plan, Social Security and DCP supplemental annuity benefits as discussed above is payable upon retirement at the later of age 62 or after 10 years of service. Participants become vested for 50 percent of this benefit after five years of service and then become vested for an additional 10 percent for each additional year of service until fully vested after 10 years of service.

A participant who is age 55 or older with at least 10 years of service is eligible for early retirement benefits. The ESRIP normal retirement benefit is reduced by 1/2 percent per month (six percent per year) for each month that the benefit commencement date precedes age 62. At December 31, 2010, Ms. Doolittle was the only Named Executive Officer eligible for early retirement benefits under the ESRIP.

The basic benefit form for ESRIP benefits is a monthly single life annuity with 10 years of guaranteed payments. The participant may choose among different annuity forms that are the actuarial equivalent of the basic benefit.

Supplemental Executive Retirement Plan

The Supplemental Executive Retirement Plan (SERP) is a non-qualified pension plan providing supplemental retirement benefits to persons who become executive officers after September 1, 2004, including Mr. Anderson, Ms. Kirkpatrick and Mr. White. The SERP is divided into two tiers, with persons who became executive officers between September 1, 2004 and December 1, 2006 (Mr. Anderson and Ms. Kirkpatrick) being participants in SERP Tier 1, and persons who become executive officers after December 1, 2006 (Mr. White) being participants in SERP Tier 2. Participants must complete five years of service before becoming 100 percent vested in SERP benefits.

SERP Tier 1

Under SERP Tier 1, a target lump sum retirement benefit is determined for each participant, which is then reduced by the lump sum actuarial equivalent of the participant’s NBU Plan benefit, Social Security benefit and any supplemental annuity under the DCP, in each case valued as of and assuming commencement at age 65. Final average pay for purposes of calculating SERP Tier 1 benefits generally consists of the participant’s highest average salary and annual incentive for any five consecutive compensation years in the last 10 years of employment. To help control the cost of future benefits under the SERP, the Board authorized SERP amendments in 2009 to provide that, commencing with annual incentives paid for 2010 performance, annual incentive compensation in excess of 125 percent of target will be excluded from the calculation of final average pay.

The target lump sum retirement benefit is equal to 40 percent of final average pay for each of the participant’s first 15 years of service, resulting in a maximum target benefit of six times final average pay after 15 years of service. A normal retirement benefit equal to the target benefit reduced by the lump sum actuarial equivalents of NBU Plan, Social Security and DCP supplemental annuity benefits as discussed above is payable as a lump sum upon retirement at or after age 60. Upon termination of employment at any time after becoming vested, a participant will receive a termination benefit equal to the SERP Tier 1 normal retirement benefit reduced by 5/12 percent per month (five percent per year) for each month that termination of employment precedes age 60, up to a maximum reduction of 60 percent for termination at age 48 or below. Participants may choose among different annuity forms that are the actuarial equivalent of the basic lump sum benefit.

SERP Tier 2

As discussed above, final average earnings for purposes of calculating benefits under the NBU Plan excludes amounts of compensation over a limit ($245,000 in 2010) imposed by the Internal Revenue Code. SERP Tier 2 provides a make-up benefit calculated using the NBU Plan formula (see Retirement Plan for Non-Bargaining Unit Employees, above) without applying this limit. Accordingly, benefits under SERP Tier 2 are equal to (a) the benefits that would be calculated under the NBU Plan if compensation taken into account when determining final average earnings was not limited by the Internal Revenue Code and did not exclude amounts deferred under our non-qualified deferred compensation plans, minus (b) the sum of the actual NBU Plan benefits and the DCP supplemental annuity benefits. SERP Tier 2 benefits are generally payable in the same form and for the same period of time as the annuity payable under the NBU Plan, subject to certain requirements for the timing of commencement of benefits.

All amounts reported in the Executive Contributions and NW Natural Contributions columns are also included in amounts reported in the Summary Compensation Table above for either 2009 or 2010. The portion of the amounts reported in the Aggregate Earnings column that represents above-market earnings is included in column (h) of the Summary Compensation Table, and the amount of above-market earnings for each Named Executive Officer is set forth in footnote 4 to that table. Of the amounts reported in the Aggregate Balance column, the following amounts have been reported in the Summary Compensation Tables in this proxy statement or in prior year proxy statements: Mr. Kantor, $525,199; Mr. Anderson, $348,294; Ms. Doolittle, $331,842; Mr. White $219,235; and Ms. Kirkpatrick, $0. Amounts not previously reported consist of market-rate earnings on amounts deferred and amounts deferred before designation as a Named Executive Officer.

Non-Qualified Deferred Compensation Plans

We currently maintain two non-qualified deferred compensation plans for executive officers: the Executive Deferred Compensation Plan (the EDCP) and the Deferred Compensation Plan for Directors and Executives (the DCP). Prior to 2005, the EDCP was the plan pursuant to which our executives deferred compensation. On January 1, 2005, deferrals under the EDCP were discontinued and the DCP became effective for future deferrals of compensation by our executives. Accordingly, all deferred contributions in 2010 were made under the DCP, while earnings continued to accrue on EDCP account balances.

Participants in the DCP may elect in advance to defer up to 50 percent of their salaries, up to 100 percent of their annual incentives, and up to 100 percent of performance share awards under our Long Term Incentive Plan. We make matching contributions each year equal to (a) the lesser of 60 percent of the participant’s salary and annual incentive deferred during the year under both the DCP and our 401(k) Plan or 3.6 percent of the participant’s total salary and annual incentive for the year, reduced by (b) the maximum matching contribution we would have made under our 401(k) Plan if the participant had fully participated in that plan.

All amounts deferred under the EDCP or the DCP have been or will be credited to either a “stock account” or a “cash account.” Under the DCP, deferrals of compensation payable in cash are made to cash accounts and deferrals of compensation payable in our Common Stock are made to stock accounts, except that participants were permitted to elect to defer performance share award payouts made prior to 2009 into cash accounts. No transfers between a participant’s cash account and stock account are permitted under the EDCP. Under the DCP, transfers from a cash account to a stock account are permitted, but not vice-versa. Stock accounts represent a right to receive shares of our Common Stock on a deferred basis, and are credited with additional shares based on the deemed reinvestment of dividends. Accordingly, the rate of earnings on stock accounts over the previous five years ending December 31, 2010 was approximately 12.81 percent representing the total shareholder return

of our Common Stock annualized, assuming dividend reinvestment, and in 2010 was approximately 6.90 percent, representing the total shareholder return of our Common Stock annualized, assuming dividend reinvestment. Cash accounts under the EDCP are credited quarterly with interest at a rate equal to Moody’s Average Corporate Bond Yield plus two percentage points, subject to a six percent minimum rate. The average interest rate paid on EDCP cash accounts in 2010 was 7.57 percent. Cash accounts under the DCP are credited quarterly with interest at a rate equal to Moody’s Average Corporate Bond Yield without the additional two percentage points or the six percent minimum. The average interest rate paid on DCP cash accounts in 2010 was 5.57 percent.

Participants make elections regarding distributions of their accounts at the time they elect to defer compensation, and have limited rights to change these payment elections. Distributions may commence on a predetermined date while still employed or upon termination of employment, and may be made in a lump sum or in annual installments over five, 10 or 15 years. Hardship withdrawals are permitted under both the EDCP and the DCP, and participants in the EDCP may withdraw their full account balance at any time subject to forfeiture of 10 percent of the balance.

POTENTIAL PAYMENTS UPON TERMINATION OR CHANGE IN CONTROL

Change in Control Compensation

We have agreed to provide certain benefits to the Named Executive Officers upon a “change in control” of NW Natural, although certain of the benefits are only payable if the Named Executive Officer’s employment is terminated without “cause” or by the officer for “good reason” within 24 months after the change in control. In our plans and agreements, “change in control” is generally defined to include:

the acquisition by any person of 20 percent or more of our outstanding Common Stock,

the nomination (and subsequent election) of a majority of our directors by persons other than the incumbent directors, and

the consummation of a sale of all or substantially all of our assets, or an acquisition of NW Natural through a merger or share exchange.

In our plans and agreements, “cause” generally includes willful and continued failure to substantially perform assigned duties or willfully engaging in illegal conduct injurious to NW Natural, and “good reason” generally includes a change in position or responsibilities (that does not represent a promotion), a decrease in compensation, or a home office relocation of over 30 miles.

The following table shows the estimated change in control benefits that would have been payable to the Named Executive Officers if (i) a change in control had occurred on December 31, 2010, and (ii) each officer’s employment was terminated on that date either by us without “cause” or by the officer with “good reason.”

Cash Severance Benefit. Each Named Executive Officer has entered into a severance agreement providing for, among other things, cash severance benefits payable if the officer’s employment is terminated by us without “cause” or by the officer for “good reason” within 24 months after a change in control. The cash severance benefit for each Named Executive Officer is equal to two times (2.5 times for Mr. Kantor) the sum of final annual salary plus average annual incentive for the last three years (annualized for annual incentives paid for partial years). These amounts are payable in a lump sum within five days after termination. The agreements provide for the following reductions in the cash severance benefit based on age at the time of termination: 10% reduction at age 62, 40% reduction at age 63, 70% reduction at age 64, and 100% reduction at age 65.

Under the severance agreements, if any payments to a Named Executive Officer in connection with a change in control would be subject to the 20 percent excise tax on “excess parachute payments” as defined in Section 280G of the Internal Revenue Code, then, if it would result in a greater net after-tax benefit for the officer to have the payments that would otherwise be made reduced by the amount necessary to prevent them from being “parachute payments,” then the officer will be paid such reduced benefits. The amounts in the above table under Cash Severance Benefit and Insurance Continuation for Mr. White and Ms. Kirkpatrick have been reduced in accordance with this provision.

Insurance Continuation. If cash severance benefits are triggered, the severance agreements also provide for the continuation of life and health insurance benefits for two years following termination of employment, but not to the extent similar benefits are provided by a subsequent employer. The amounts in the table above represent the present value of two years’ of monthly life and health insurance benefit payments at the rates paid by us for each officer as of December 31, 2010.

Performance Share Acceleration. As described above under the “Grants of Plan-Based Awards During 2010” table and “Compensation Discussion and Analysis—Compensation Programs—Long-Term Incentives—Performance Shares,” we granted performance share awards to the Named Executive Officers in February 2010 under which shares of our Common Stock (plus accumulated cash dividends) will be issued to them based on our performance over the years 2010 to 2012. Similar awards were granted in February 2009 to the Named Executive Officers under which Common Stock (and dividends) will be issued based on our performance over the years 2009 to 2011. The award agreements for all awards other than the special Gill Ranch storage project award granted to Mr. White require us to issue a calculated number of shares within five days after a change in control and provide that (i) the number of shares to be issued will be pro-rated based on the portion of the award period completed prior to the change in control, (ii) for the portion of the award payable based on total shareholder return relative to a peer group of companies, actual stock performance through the date of the change in control will be applied to determine a gross payout amount before applying the above pro-ration, and (iii) for the portion of the award payable based on achievement of strategic milestones, the payout will be based on 100 percent of the pro-rated target. These payments are required whether or not the officer’s employment is terminated in connection with the change in control. The amounts in the table above represent the number of shares that would have been issued under the awards based on stock performance through December 31, 2010, multiplied by a stock price of $46.47 per share, which was the closing price of our Common Stock on the last trading day of 2010, plus an amount equal to the dividends paid per share during the applicable award periods through December 31, 2010.

⁴

Additional Lump Sum SERP Tier 1 Benefit. As discussed above in the text accompanying the “Pension Benefits” table, two of our Named Executive Officers are participants in the SERP Tier 1, which generally provides for a lump sum benefit payable six months after termination of employment. If a SERP Tier 1 participant’s employment is terminated by us without “cause” or by the participant for “good reason” within 24 months after a change in control, the SERP Tier 1 participant will receive three additional years of service for purposes of calculating their SERP Tier 1 benefit. The amounts in the table represent the excess of the SERP benefit the participant would receive on termination following a change in control over the SERP benefit he or she would have received if employment had terminated absent a change in control on December 31, 2010.

⁵	Total Lump Sum Payments. Amounts in this column equal the sum of the amounts in the four columns to its left.

⁶	Additional Annual ESRIP and SERP Tier 2 Benefits. As discussed above in the text accompanying the “Pension Benefits” table, Mr. Kantor and Ms. Doolittle are participants in the ESRIP, which generally provides for a lifetime supplemental pension

benefit payable by us following retirement. If the employment of any ESRIP participant is terminated by us without “cause” or by the participant for “good reason” within 24 months after a change in control, the ESRIP participant will receive three additional years of service for purposes of calculating his or her ESRIP benefit. In addition, (i) the benefit reductions for commencement of ESRIP benefits prior to age 65 are reduced, from 6 percent for each year benefits commence prior to age 65 (applicable to a participant like Mr. Kantor who is not yet eligible for early retirement) or age 62 (applicable to a participant like Ms. Doolittle who is eligible for early retirement) to three percent for each year benefits commence prior to age 62; and (ii) benefits will commence immediately, or if later, at age 55 (as compared to age 57 for Mr. Kantor and age 58 for Ms. Doolittle as elected by them for terminations not involving a change in control). The amounts in the table above represent the excess of the annual ESRIP benefit each of Mr. Kantor and Ms. Doolittle would receive commencing immediately, or if later, at age 55 and giving effect to the above benefit enhancements, over the annual ESRIP benefit they would each receive commencing at the later ages set forth above assuming a voluntary termination of employment on December 31, 2010. The additional actuarial present value of these enhanced ESRIP benefits, calculated using the same mortality and discount rate assumptions as used for purposes of the “Pension Benefits” table above, is $2,643,775 and $739,023, for Mr. Kantor and Ms. Doolittle, respectively. As discussed above in the text accompanying the “Pension Benefits” table, Mr. White is a participant in the SERP Tier 2, which generally provides for a lifetime supplemental pension benefit payable by us following retirement. If the employment of any SERP Tier 2 participant is terminated by us without “cause” or by the participant for “good reason” within 24 months after a change in control, the SERP Tier 2 participant will receive three additional years of service for purposes of calculating his or her SERP Tier 2 benefit. The amount for Mr. White in the table above represents the excess of the annual SERP Tier 2 benefit he would receive on termination following a change in control over the annual SERP Tier 2 benefit he would have received if his employment had terminated absent a change in control on December 31, 2010. The additional actuarial present value of this enhanced SERP Tier 2 benefit, calculated using the same mortality and discount rate assumptions as used for purposes of the “Pension Benefits” table above, is $129,483.

Other Benefits Triggered on Certain Employment Terminations

When Mr. Kantor was promoted to President and Chief Executive Officer effective January 1, 2009, we entered into a severance agreement with him that provides the following severance benefits if we terminate his employment without cause:

80 percent of his base salary for a termination without cause during 2010, decreasing to 60 percent of base salary for a termination in 2011, 40 percent in 2012, 20 percent in 2013, and 0 percent thereafter.

For any termination without cause occurring before his 55th birthday on April 30, 2012, Mr. Kantor will be treated as eligible for early retirement benefits under the ESRIP, for which he will not otherwise be eligible unless he remains employed through his 55th birthday. The estimated value of this ESRIP modification, based on an assumed termination of Mr. Kantor’s employment on December 31, 2010, is an increase in ESRIP benefits of $62,962 per year commencing at age 57, which has an actuarial present value as of December 31, 2010, calculated using the same mortality and discount rate assumptions as used for purposes of the “Pension Benefits” table above, of $735,439.

As described above under “Grants of Plan-Based Awards During 2010” table and “Compensation Discussion and Analysis—Compensation Programs—Long-Term Incentives—Performance Shares,” we granted performance share awards to the Named Executive Officers in February 2010 under which shares of our Common Stock (plus accumulated cash dividends) will be issued to them based on our performance over the years 2010 to 2012. Similar awards were granted in February 2009 under which Common Stock (and dividends) will be issued based on our performance over the years 2009 to 2011. The award agreements generally require the officer to be employed by us on the last day of the performance period to receive an award payout, but the award agreements for all awards other than the special Gill Ranch storage project award granted to Mr. White provide that if employment terminates earlier as a result of death, disability or retirement after reaching age 60 the officer will be entitled to a pro-rated award payout. Accordingly, if any Named Executive Officer had terminated employment on December 31, 2010 as a result of death, disability or retirement, his or her target award for the 2010-2012 performance period would have been reduced to one-third of the original target award reflecting employment for one year of the three-year performance

period, and his or her target award for the 2009-2011 performance period would have been similarly reduced to two-thirds of the original target award, and then he or she would receive payouts under these adjusted awards at the end of the applicable performance periods based on our actual performance against the performance goals. Assuming achievement of target performance levels, the estimated value of the pro-rated award payouts, based on a stock price of $46.47 per share and continuation of quarterly dividends for the remainder of the performance period on our Common Stock at the current rate, for each Named Executive Officer would be: Mr. Kantor, $704,161; Mr. Anderson, $283.365; Ms. Doolittle, $128,802; Mr. White, $154,563; and Ms. Kirkpatrick, $163,160.

As of December 31, 2010, each Named Executive Officer held options to purchase Common Stock as listed in the “Outstanding Equity Awards” table above. Under the terms of their stock option agreements, upon the death or disability of the officer, all unexercisable options become fully exercisable and the standard three-month period for exercising options following termination of employment is extended to one year, but not beyond each option’s original 10-year term. If death or disability of a Named Executive Officer had occurred on December 31, 2010, the sum of (i) for outstanding unexercisable options, the aggregate value as of December 31, 2010 of those options, assuming a one-year remaining term and otherwise calculated using the Black-Scholes option pricing model with the same assumptions used for valuing our options under ASC 718, plus (ii) for outstanding exercisable options, the increase in value of those options resulting from the extension of the post-termination exercise period from three months to one year with the option values as of December 31, 2010 for three-month and one-year remaining terms calculated using the Black-Scholes option pricing model with the same assumptions used for valuing our options under ASC 718, for each of the Named Executive Officers was Mr. Kantor, $309,261, Mr. Anderson, $115,990; Ms. Doolittle, $47,680 Mr. White, $55,542, and Ms. Kirkpatrick, $67,369. If an officer terminates employment when eligible for normal or early retirement under our NBU Plan, the stock option agreements provide that all unexercisable options become fully exercisable and the standard three-month period for exercising options following termination of employment is extended to three years, but not beyond each option’s original 10-year-term. As of December 31, 2010, Mr. White was the only Named Executive Officer eligible for normal or early retirement under the NBU Plan. If he had retired on December 31, 2010, the aggregate value of option enhancements calculated as described above but using a three-year remaining term instead of a one-year remaining term was $79,672.

Non-Employee Director Compensation Philosophy

The OECC’s compensation philosophy for non-employee members of the Board of Directors is designed to attract and retain high performing directors who will perform in the best interest of shareholders. The OECC targets the compensation of Board members to be aligned with the middle of the market (50^th percentile) for about 24 peer companies. The OECC reviews Board compensation every two years and recommends adjustments to compensation only as necessary. Towers Perrin, the same consulting firm that assists the OECC with executive compensation, provides competitive market data for Board compensation.

While the components of compensation have evolved over the years, the current pay components consist of a cash retainer, cash meeting fees, and extra cash retainers for serving as chair of the Board or of committees of the Board.

The Board has adopted stock ownership guidelines that require directors to own NW Natural shares valued at the lesser of $300,000 or five times their annual retainer within five years of joining the Board, including amounts deferred pursuant to the plans described below. The OECC last reviewed the progress of the directors in achieving these stock ownership objectives in February 2011 and concluded that all of the directors have achieved the stock ownership goals.

Deferred Compensation Plans

Directors Deferred Compensation Plan

Prior to January 1, 2005, directors could elect to defer the receipt of all or a part of their directors’ compensation fees (cash or stock retainers and meeting fees) under our non-qualified Directors Deferred Compensation Plan (DDCP). At the director’s election, deferred amounts were credited to either a “cash account” or a “stock account.” If deferred amounts were credited to stock accounts, such accounts were credited with a number of shares based on the purchase price of our Common Stock on the next purchase date under our Dividend Reinvestment and Direct Stock Purchase Plan, and such accounts were credited with additional shares based on the deemed reinvestment of dividends. Cash accounts are credited quarterly with interest at a rate equal to Moody’s Average Corporate Bond Yield plus two percentage points and the crediting rate is subject to a six percent minimum rate. The rate is adjusted quarterly. At the election of the participant, deferred balances in the stock and/or cash accounts are payable after termination of Board service in a lump sum, in installments over a period not to exceed 10 years, or in a combination of lump sum and installments.

In September 2004, the Board approved an amendment to the DDCP partially terminating the plan so that no deferrals will be made to the plan subsequent to December 31, 2004. All amounts deferred into the plan prior to December 31, 2004 will remain in the plan and all other provisions of the DDCP remain in effect.

Deferred Compensation Plan for Directors and Executives

In January 2005, the Deferred Compensation Plan for Directors and Executives (DCP) replaced the existing DDCP as the vehicle for non-qualified deferral of compensation by directors. See “Non-qualified Deferred Compensation Plans,” above. Our obligation to pay deferred compensation in accordance with the terms of the DCP will generally become due on retirement, death, or other termination of service, and will be paid in a lump sum or in

installments of five, 10 or 15 years as elected by the participant in accordance with the terms of the DCP. The right of each participant in the DCP is that of one of our general, unsecured creditors.

Directors Retirement Benefit

On January 1, 1998, in connection with the termination of a prior retirement benefit for directors and in lieu of that benefit, we credited a number of shares of our Common Stock to a stock account under the DDCP for each then current director. If such a director retired from the Board at age 70 or older with 10 or more years of service as a director or if the director earlier died or became disabled or if there was an earlier change in control of NW Natural, we were obligated to deliver to the director (or to his or her beneficiary) the number of shares credited to the account, plus an additional number of shares based on reinvested dividends credited to the account over time. Concurrently with the creation of the stock accounts, we contributed to the Umbrella Trust for Directors a number of shares of our Common Stock equal to the number of shares credited to directors’ accounts. Such stock is held in the Umbrella Trust and will be used to fund our obligation to pay out the stock accounts. In February 2008, the Board of Directors amended the DDCP such that each of the directors with this benefit became fully vested in the shares. At that time, the number of shares credited to retirement benefit accounts of then-current directors were as follows: Mr. Hamachek, 919 shares; and Mr. Tromley, 1,415 shares.

Director Perquisites and Other Compensation

We do not provide perquisites to our directors of other than nominal value and no director received perquisites at or exceeding a total value of $10,000 in 2010.

2010 AND 2009 AUDIT FIRM FEES

Pre-Approval Policy for Audit and Non-Audit Services

The Audit Committee approved 100 percent of 2010 and 2009 services for audit, audit-related, tax services and all other fees, including audit services relating to compliance with Section 404 of the Sarbanes-Oxley Act. The Chair of the Audit Committee is authorized to pre-approve non-audit services between meetings of the Audit Committee and must report such approvals at the next Audit Committee meeting. See “Report of the Audit Committee,” below.

REPORT OF THE AUDIT COMMITTEE

The Audit Committee of the Board of Directors (Committee) is responsible for providing independent, objective oversight of NW Natural’s accounting and auditing functions, financial reporting and internal control over financial reporting. The Committee is solely responsible for the engagement of the independent registered public accounting firm on behalf of NW Natural, and the independent registered public accounting firm reports to the Committee. The Committee acts under a written charter, amended as of July 22, 2010, to ensure compliance with applicable laws and regulations. The charter is reviewed annually by the Committee and is available at www.nwnatural.com. Each of the members of the Committee is independent as defined by current New York Stock Exchange listing standards and NW Natural’s Director Independence Standards. The Board of Directors has designated John D. Carter, chair of the committee, as an “audit committee financial expert.”

The Committee, in accordance with its written charter, oversees the quality and integrity of NW Natural’s accounting, auditing and financial reporting practices. During fiscal year 2010, the Committee discussed the interim financial information in each of NW Natural’s quarterly reports to the Securities and Exchange Commission (SEC) in special meetings with the Chief Executive Officer, the Chief Financial Officer, the Controller, and PricewaterhouseCoopers LLP, NW Natural’s independent registered public accounting firm, prior to filing them with the SEC. In addition, the Chair of the Committee and available Committee members review NW Natural’s quarterly earnings press release before its dissemination.

During 2010, the Committee reviewed disclosure controls and procedures designed to ensure the continuing integrity of NW Natural’s financial reports and executive compensation disclosure. The Committee provided regular oversight of NW Natural’s assessment of its internal control over financial reporting in compliance with Section 404 of the Sarbanes-Oxley Act of 2002.

In fulfilling its responsibilities, the Committee has reviewed and discussed the audited financial statements contained in NW Natural’s Annual Report on Form 10-K for the year ended December 31, 2010 with NW Natural’s management and the independent registered public accounting firm. As part of its review, the Committee discussed NW Natural’s critical accounting policies and matters of judgment and estimates used in the preparation of the financial statements included in NW Natural’s 2010 Annual Report on Form 10-K. In addition, the Committee discussed with the independent registered public accounting firm those matters required to be discussed by Statement on Auditing Standards No. 61, as amended by the Public Accounting Oversight Board (PCAOB) AU 380, Communications with Audit Committees.

In discharging its oversight responsibility as to the audit process, the Committee obtained from the independent registered public accounting firm written disclosures and the letter required by the PCAOB Ethics and Independence Rule 3526, Communication with Audit Committees Concerning Independence, and has discussed with the independent registered public accounting firm the independent registered public accounting firm’s independence. In this regard, the Committee considered whether or not the provision of non-audit services by the independent registered public accounting firm for the year ended December 31, 2010 is compatible with maintaining the independence of the firm and determined that none of the services provided to NW Natural impacted a finding of independence. In addition, for year ended December 31, 2010, the Committee reviewed the relationship with its registered public accounting firm, PricewaterhouseCoopers LLP. Based upon the Committee’s assessment and satisfaction with the services provided, the Committee determined it was in NW Natural’s best interest to continue its engagement of PricewaterhouseCoopers LLP.

In February 2010, the Committee pre-approved certain non-audit services performed by NW Natural’s independent registered public accounting firm and affirmed its procedure for the pre-approval of any future non-audit services performed by its independent auditor. On February 24, 2011, the Committee pre-approved specific services to be performed by the independent auditor in 2011, including audit, audit-related and tax services, and established its procedure for pre-approval of all other services to be performed by the independent auditor in 2011. The Committee determined that:

for proposed non-audit services, management will submit to the Committee a list of non-audit services that it recommends the Committee engage the independent registered public accounting firm to provide;

the Committee will review and consider for approval the list of permissible non-audit services and the budget for such services;

management will routinely inform the Committee regarding the non-audit services actually provided by the independent auditor pursuant to this pre-approval process; and

the Director of Internal Auditing will be responsible for reporting at least annually to the Committee all independent registered public accounting firm fees and the pre-approved budget for such services.

The Chair of the Committee is authorized to pre-approve non-audit services between meetings of the Committee and must report such approvals at the next Committee meeting.

The Committee also discussed with the independent registered public accounting firm any relationships that may impact its objectivity and independence and satisfied itself as to the auditor’s independence. The Committee also completed its annual assessment of the independent registered public accounting firm’s and internal auditors’ performance. The Committee discussed with management and the internal auditors the quality, adequacy and effectiveness of NW Natural’s internal control over financial reporting, and the organization, responsibilities, budget and staffing of the internal audit function. The Committee reviewed with the independent registered public accounting firm any significant matters regarding NW Natural’s internal control over financial reporting that had come to their attention during the conduct of their audit. The Committee reviewed with both the independent registered public accounting firm and the internal auditors their respective audit plans, audit scopes and identification of audit risks.

The Committee, in reliance on the reviews and discussions referred to above, recommended to the Board of Directors (and the Board has approved and directed) that the audited consolidated financial statements be included in Northwest Natural Gas Company’s Annual Report on Form 10-K for the year ended December 31, 2010, for filing with the SEC.

Respectfully submitted to the Board of Directors on February 24, 2011 by the Audit Committee:


		John D. Carter, Chair		Jane L. Peverett
		Martha L. “Stormy” Byorum		Kenneth Thrasher
		Tod R. Hamachek		Russell F. Tromley

PROPOSAL 2—PROPOSED REAPPROVAL AND AMENDMENT OF

LONG TERM INCENTIVE PLAN

In December 2000 the Board of Directors adopted, and in May 2001 the shareholders approved, the Company’s Long Term Incentive Plan (the Plan). The Plan was reapproved without amendment by the shareholders in May 2006. The Plan gives the Board of Directors broad authority to make long term stock incentive awards and, in its discretion, to qualify such awards as “performance-based compensation” as defined under Section 162(m) of the Internal Revenue Code of 1986 (the Code), thereby permitting full deductibility of any amounts paid under such awards to the Named Executive Officers. The Code requires that the Plan be reapproved by the shareholders at least once every five years in order for awards under the Plan to continue to qualify as performance-based compensation, and the Plan is being submitted to shareholders for that reason.

As of March 15, 2011, there were 274,155 shares available for issuance under the Plan, and target awards for a total of 82,500 shares were outstanding. To ensure that sufficient shares are authorized for the Plan to cover awards for the next five years at grant levels consistent with recent practice, the Board of Directors believes that additional shares are needed. Accordingly, in February 2011, the Board of Directors approved an amendment to the Plan, subject to shareholder approval, to reserve an additional 100,000 shares of Common Stock for the Plan, thereby increasing the total number of shares reserved for issuance under the Plan from 500,000 to 600,000 shares.

The material terms of the Plan are described below, and a complete copy of the Plan, marked to show the proposed amendment, is attached to this Proxy Statement as Appendix A.

Eligibility

All employees, officers and directors of the Company and its subsidiaries are eligible to receive awards under the Plan.

Shares Available

The Plan provides that not more than 500,000 shares of Common Stock may be issued pursuant to the Plan. Since the Plan was adopted in 2001, a total of 143,345 shares have been issued under the Plan. The proposed amendment will increase the number of shares available for issuance under the Plan by 100,000 shares.

Administration

The Plan states that it is administered by the Board of Directors, which may adopt rules and regulations for the operation of the Plan and generally supervises the administration of the Plan. The Board of Directors may delegate to a committee of the Board of Directors or specified officers of the Company, or both, authority to administer the Plan, except that only the Board of Directors may amend, modify or terminate the Plan. The Board of Directors has delegated to the Organization and Executive Compensation Committee (OECC) general authority for making awards under the Plan. The OECC determines individuals to whom awards are made under the Plan and the terms of any such awards.

Term of Plan

The Plan will continue until all shares available for issuance under the Plan have been issued and all restrictions on such shares have lapsed. The Board of Directors may suspend or terminate the Plan at any time.

Stock Bonus Awards

The OECC may award Common Stock as a stock bonus under the Plan. The OECC may determine the persons to receive awards, the number of shares to be awarded and the time of the award. No cash consideration (other than tax withholding amounts) will be paid by employees to the Company in connection with stock bonuses. Stock received as a stock bonus is subject to the terms, conditions and restrictions determined by the OECC at the time the stock is awarded. Restrictions may include restrictions concerning transferability and forfeiture of the shares. Stock bonus shares which are forfeited to the Company are again available for issuance under the Plan.

Restricted Stock

The Plan provides that the Company may issue restricted shares in such amounts, for such consideration (including promissory notes and services), subject to such restrictions and on such terms as the OECC may determine. Restrictions may include restrictions concerning transferability, repurchase by the Company and forfeiture of the shares. Restricted shares that are forfeited to or repurchased by the Company are again available for issuance under the Plan.

Performance-based Awards

The OECC may grant Performance-based Awards denominated either in Common Stock or in dollar amounts. All or part of the awards will be earned if performance goals established by the OECC for the period covered by the award are met and the employee satisfies any other restrictions established by the OECC. The performance goals may be expressed as one or more targeted levels of performance with respect to one or more of the following objective measures with respect to the Company or any subsidiary, division or other unit of the Company: earnings, earnings per share, stock price increase, total shareholder return (stock price increase plus dividends), return on equity, return on assets, return on capital, economic value added, revenues, operating income, inventories, inventory turns, cash flows or any of the foregoing before the effect of acquisitions, divestitures, accounting changes, and restructuring and special charges. Performance-based Awards may be paid in cash or Common Stock and may be made as awards of restricted shares subject to forfeiture if performance goals are not satisfied, as determined by the OECC. No employee may receive in any fiscal year Performance-based Awards denominated in Common Stock under which the aggregate amount payable under the Awards exceeds the equivalent of 50,000 shares of Common Stock or Performance-based Awards denominated in dollars under which the aggregate amount payable under the Awards exceeds $1,000,000. The payment of a Performance-based Award in cash will not reduce the number of shares reserved under the Plan.

Changes in Capital Structure

The Plan provides that if the outstanding Common Stock is 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, stock dividend or recapitalization, appropriate adjustment will be made by the OECC in the number and kind of shares available for awards under the Plan.

Tax Consequences

An employee who receives stock in connection with the performance of services will generally realize taxable income at the time of receipt unless the shares are substantially nonvested for purposes of Section 83 of the Code. Absent an election under Section 83(b), an employee who receives substantially nonvested stock in connection with performance of services will realize taxable income in each year in which a portion of the shares substantially

vest. The Company will generally be entitled to a tax deduction in the amount includable as income by the employee at the same time or times as the employee recognizes income with respect to the shares.

Section 162(m) of the Code limits to $1,000,000 per person the amount that the Company may deduct for compensation paid to any individual who, on the last day of the taxable year, is its chief executive officer or one of its three other highest compensated officers (excluding the chief financial officer). Under IRS regulations, compensation received through a performance-based award will not be subject to the $1,000,000 limit if the performance-based award and the plan meet certain requirements. One such requirement is shareholder approval at least once every five years of the performance criteria upon which award payouts will be based and the maximum amount payable under awards, both of which are set forth in Section 8 of the Plan. Approval of this proposal will constitute reapproval of the performance criteria and maximum amounts under the Plan previously approved by shareholders. Other requirements are that objective performance goals and the amounts payable upon achievement of the goals be established by a committee of at least two outside directors and that no discretion be retained to increase the amount payable under the awards. The Company believes that, if this proposal is approved by the shareholders, compensation received on vesting of Performance-based Awards granted under the Plan in compliance with all of the above requirements will continue to be exempt from the $1,000,000 deduction limit.

Plan Benefits

In 2010, the Company granted Performance-based Awards under the Plan to the Named Executive Officers, the amounts of which are set forth in the table above under “Executive Compensation—Grants of Plan-Based Awards During 2010” and the terms of which are summarized above under “Compensation Discussion and Analysis–Compensation Programs–Long-Term Incentives–Performance Shares.” In total, the Company granted Performance-based Awards in 2010 on the same terms to all current executive officers as a group at an aggregate target award level of 38,500 shares, and to all other employees as a group at an aggregate target award level of 3,000 shares.

Shares issued pursuant to the LTIP do not include an exercise price, but are payable when the award criteria are satisfied. If the maximum awards were paid pursuant to the performance-based awards outstanding at December 31, 2010, the number of shares shown in column (a) would increase by 82,500 shares and the number of shares shown in column (c) would decrease by 82,500 shares.

Prior to January 1, 2005, deferred amounts were credited, at the participant’s election, to either a “cash account” or a “stock account.” If deferred amounts were credited to stock accounts, such accounts were credited with a number of shares of NW Natural common stock based on the purchase price of the common stock on the next purchase date under our Dividend Reinvestment and Direct Stock Purchase Plan, and such accounts were credited with additional shares based on the deemed reinvestment of dividends. Cash accounts are credited quarterly with interest at a rate equal to Moody’s Average Corporate Bond Yield plus two percentage points, subject to a six percent minimum rate. At the election of the participant, deferred balances in the stock accounts are payable after termination of Board service or employment in a lump sum, in installments over a period not to exceed 10 years in the case of the DDCP, or 15 years in the case of the EDCP, or in a combination of lump sum and installments. We have contributed common stock to the trustee of the Umbrella Trusts such that the Umbrella Trusts hold approximately the number of shares of common stock equal to the number of shares credited to all participants’ stock accounts.

Effective January 1, 2005, the EDCP and DDCP were replaced by the DCP. The DCP continues the basic provisions of the EDCP and DDCP under which deferred amounts are credited to either a “cash account” or a “stock account.” Stock accounts represent a right to receive shares of NW Natural common stock on a deferred basis, and such accounts are credited with additional shares based on the deemed reinvestment of dividends. Effective January 1, 2007, cash accounts are credited quarterly with interest at a rate equal to Moody’s Average Corporate Bond Yield. Our obligation to pay deferred compensation in accordance with the terms of the DCP will generally become due on retirement, death, or other termination of service, and will be paid in a

lump sum or in installments of 5, 10 or 15 years as elected by the participant in accordance with the terms of the DCP. We have contributed common stock to the trustee of the Supplemental Trust such that this trust holds approximately the number of common shares equal to the number of shares credited to all participants’ stock accounts. The right of each participant in the DCP is that of a general, unsecured creditor of the Company.

Vote Required

Reapproval and amendment of the Plan by the shareholders will require the affirmative vote of the holders of a majority of the shares of Common Stock of the Company present, or represented by proxy, and entitled to vote on the matter at the Annual Meeting. Abstentions have the effect of “no” votes in determining whether this proposal is approved. Broker non-votes are counted for purposes of determining whether a quorum exists at the Annual Meeting but are not counted and have no effect on the results of the vote.

The Board of Directors recommends a vote FOR this proposal.

PROPOSAL 3—ADVISORY VOTE ON EXECUTIVE COMPENSATION

This proxy statement includes extensive disclosure regarding the compensation of our Named Executive Officers under the heading “Executive Compensation” on pages 26 to 62 above. Section 14A of the Securities Exchange Act of 1934, enacted as part of the Dodd-Frank Wall Street Reform and Consumer Protection Act in July 2010, requires us to submit to our shareholders a nonbinding advisory resolution to approve the compensation of the Named Executive Officers disclosed in this proxy statement. Accordingly, the Board of Directors has approved the submission of the following resolution to the shareholders for approval at the Annual Meeting:

“RESOLVED, that the compensation of the Company’s Named Executive Officers, as disclosed pursuant to Item 402 of Regulation S-K under the heading “Executive Compensation” in the Proxy Statement for the Company’s 2011 Annual Meeting of Shareholders, is approved.”

This proposal gives you the opportunity to endorse or not endorse our executive compensation program by voting for or against the above resolution. As discussed under “Executive Compensation—Compensation Discussion and Analysis” above, our executive compensation programs have been carefully designed and implemented to attract, retain and motivate talented and qualified executives, to link compensation to achievement of annual and long-term performance goals, to align executives’ interests with shareholders’ interests, to emphasize pay for performance and to achieve a correct balance between compensation that is attractive to executives, affordable to the Company and fair to shareholders and employees.

Substantial components of executive compensation are tied to the Company’s annual and long-term performance. For example, the Executive Annual Incentive Plan, which is designed to encourage and reward executive officer’s contributions in achieving NW Natural’s annual goals, provides for cash payments that are based on a formula that includes earnings per share, return on invested capital, Company performance relative to other operational goals and individual performance. Similarly, NW Natural’s Long Term Incentive Plan is designed to align executives’ interests with shareholder interests, by rewarding total shareholder return performance relative to the Company’s peer group and focusing executives on key long-term objectives and long-term business results that align with the creation of shareholder value. Performance share awards under the Long Term Incentive Plan have a performance period of three years and are based 75 percent on total shareholder return and 25 percent on achievement of performance milestones relative to strategic plan goals. Additionally, NW Natural’s pay practices work to align executives’ interests with shareholders’ interests by emphasizing stock ownership through stock ownership guidelines and the provision of compensation under the Stock Option Plan and the Long Term Incentive Plan.

Over the last few years, NW Natural has also adopted a number of pay practices that emphasize fairness to shareholders. Among other practices, executive change in control severance agreements are double-trigger and contain no gross-up provisions, with declining levels of benefits as executives approach age 65. Additionally, the OECC has eliminated perquisites for executives, reduced the interest crediting rate on compensation deferred after 2004 to a variable market rate, modified the Executive Supplemental Retirement Income Plan (ESRIP) and Supplemental Retirement Plan (SERP) to reduce benefits and expenses, including limiting the amount of an executive’s annual bonus that is included in final average compensation for purpose of those plans, eliminated the annual payment of ESRIP-related FICA tax on behalf of ESRIP participants, closed new participation in the ESRIP and Tier I of the SERP, and increased the percentage of total targeted direct compensation that is at-risk, particularly for the Chief Executive Officer. Moreover, NW Natural’s annual and long-term incentive awards contain provisions that “clawback” from executives certain benefits under those awards in the event of misconduct.

Overall, NW Natural’s compensation practices are driven by our total compensation philosophy which is designed to provide total remuneration in a manner that motivates high levels of performance, creates shareholder value, and emphasizes our commitment to tie a significant portion of executive compensation to the Company’s performance.

Vote Required

Approval of this proposal by the shareholders will require that the votes cast in favor of the proposal at the Annual Meeting exceed the votes cast against the proposal. Abstentions and broker non-votes will be counted for purposes of determining whether a quorum exists at the Annual Meeting, but will have no effect on the results of the vote on this proposal.

The Board of Directors recommends a vote FOR this proposal.

PROPOSAL 4—ADVISORY VOTE ON FREQUENCY OF VOTING ON

EXECUTIVE COMPENSATION

Section 14A of the Securities Exchange Act of 1934 requires us to submit the resolution in Proposal 3 above to a shareholder vote at least once every three years, and also requires us at least once every six years to submit to shareholders for a nonbinding advisory vote the question of whether the resolution in Proposal 3 should be voted on every year, every two years or every three years. Accordingly, the Board of Directors has approved the submission of this question to a vote of the shareholders at the Annual Meeting.

The Board of Directors recommends that you vote to hold a non-binding advisory vote on executive compensation every three years. Our reasons for this recommendation are:

Our executive compensation programs avoid problematic pay practices, are straightforward and are consistently implemented. Accordingly, we think that an advisory vote every three years provides shareholders with timely and appropriate input, while avoiding the incremental program and administrative costs for both the Company and its shareholders of holding more frequent advisory votes on executive compensation with little to no additional value to shareholders for that cost.

An annual say-on-pay vote would not allow for changes to the Company’s compensation program to be in place long enough to evaluate whether the changes were effective. We believe that a three-year interval between advisory votes will provide us with the needed time to thoughtfully evaluate and respond to shareholder input, implement appropriate changes, as needed, to our executive compensation programs, and then have the results of those changes reflected in compensation disclosed in the proxy statement for the next advisory vote three years later.

A three-year vote matches our three-year long-term incentive cycles. In determining the interval to recommend to shareholders, the Board considered that the ultimate goal of corporate performance is to increase long-term shareholder value. This is reflected by the fact that 51 percent or more of the total direct compensation to each of the Named Executive Officers is at risk and tied to incentive performance; accordingly, a significant portion of the elements of executive compensation do not typically change in a significant manner from year to year.

At this meeting we are also seeking shareholder reapproval of our Long Term Incentive Plan, and do so every five years which allows shareholders to approve or disapprove the design of that plan in a binding vote. See Proposal 2 above. We also request shareholder reapproval of our Restated Stock Option Plan every five years in a binding vote. Each of these reapprovals provide shareholders an additional opportunity to vote on components of executive compensation.

The Board of Directors recommends a vote for EVERY THREE YEARS on this proposal.

PROPOSAL 5—RATIFICATION OF APPOINTMENT OF

INDEPENDENT REGISTERED PUBLIC ACCOUNTANTS

At a meeting held February 24, 2011, the Audit Committee of the Board of Directors appointed PricewaterhouseCoopers LLP, independent registered public accounting firm, to audit the books, records and accounts of NW Natural for fiscal year 2011. The Audit Committee and the Board of Directors recommend that the shareholders ratify this appointment.

Representatives of PricewaterhouseCoopers LLP will be present at the Annual Meeting with the opportunity to make a statement if they desire to do so, and will be available to respond to appropriate questions.

See “2010 and 2009 Audit Firm Fees,” above.

Vote Required

The ratification of the appointment of PricewaterhouseCoopers LLP as independent registered public accountants for 2011 will require the affirmative vote of the holders of a majority of the shares of Common Stock of NW Natural present, or represented by proxy, and entitled to vote on the matter at the Annual Meeting. Abstentions have the effect of “no” votes in determining whether the proposal is ratified. Broker non-votes are counted for purposes of determining whether a quorum exists at the Annual Meeting but are not counted and have no effect on the results of the vote.

The Audit Committee and the Board of Directors recommend a vote FOR this proposal.

OTHER MATTERS

Management does not know of any other matters to be presented at the Annual Meeting. If other matters should be properly presented at the meeting, the persons named in the accompanying proxy will vote the shares represented by such proxy with respect to such matters in accordance with their best judgment.

Consolidation Services Provided

The consolidation of an individual’s multiple proxy cards into one envelope is a service NW Natural provides based on Social Security Number or Tax ID Number match.

If you received a consolidated mailing this year and you would like to receive a separate annual report or proxy statement for each account with the same Social Security Number, please submit your request to Shareholder Services, 220 NW Second Avenue, Portland, OR 97209 or call (800) 422-4012, ext. 3412. NW Natural will promptly send additional copies of the annual report and/or proxy statement upon receipt of such request. You may also contact NW Natural if you received multiple copies of the Annual Meeting materials and would prefer to receive a single copy in the future.

Delivery of Proxy Materials to Households

Only one copy of our annual report and proxy statement will be delivered to an address where two or more shareholders reside unless we have received contrary instructions from a shareholder at the address. A separate proxy card will be delivered to each shareholder at the shared address.

If you are a shareholder who lives at a shared address and you would like additional copies of the annual report, this proxy statement, or any future annual reports or proxy statements, contact Shareholder Services, 220 NW Second Avenue, Portland, OR 97209 or call (800) 422-4012, ext. 3412. NW Natural will promptly send additional copies of the annual report and/or proxy statement upon receipt of such request.

If you share the same address with another NW Natural shareholder and you currently receive multiple copies of annual reports or proxy statements, you may request delivery of a single copy of future annual reports or proxy statements at any time by calling Shareholder Services at (800) 422-4012, ext. 3412, or by writing Shareholder Services, 220 NW Second Avenue, Portland, OR 97209.

Many brokerage firms and other shareholders of record have procedures for the delivery of single copies of company documents to households with multiple beneficial shareholders. If your family has one or more “street name” accounts under which you beneficially own shares of NW Natural Common Stock, please contact your broker, financial institution, or other shareholder of record directly if you require additional copies of this proxy statement or NW Natural’s annual report, or if you have other questions or directions concerning your “street name” account.

2012 ANNUAL MEETING OF SHAREHOLDERS

The SEC’s proxy rules require that any shareholder proposal to be considered for inclusion in NW Natural’s proxy statement for the 2012 Annual Meeting of Shareholders must be received at NW Natural’s principal executive office no later than December 21, 2011.

NW Natural’s bylaws require shareholders to give NW Natural advance notice of any proposal to be submitted at any meeting of shareholders. The bylaws prescribe the information to be contained in any such notice, and a copy of the relevant provisions of the bylaws will be provided to any shareholder upon written request to the Corporate Secretary of NW Natural. For any shareholder proposal to be considered at the 2012 Annual Meeting of Shareholders, the shareholder’s notice must be received by NW Natural’s Corporate Secretary no later than February 25, 2012. The SEC’s proxy rules allow NW Natural to use discretionary voting authority to vote on a matter coming before an annual meeting of shareholders which is not included in NW Natural’s proxy statement, if NW Natural does not have notice of the matter before the deadline established in its bylaws. In addition, discretionary voting authority may generally also be used if NW Natural receives timely notice of such matter (as described above) and if, in the proxy statement, NW Natural describes the nature of such matter and how NW Natural intends to exercise its discretion to vote on such matter.

APPENDIX A

NORTHWEST NATURAL GAS COMPANY

LONG TERM INCENTIVE PLAN¹

1. Purpose. The purpose of this Long Term Incentive Plan (the “Plan”) is to enable Northwest Natural Gas Company (the “Company”) to attract and retain the services of selected employees, officers and directors of the Company or of any subsidiary of the Company.

2. Shares Subject to the Plan. Subject to adjustment as provided below and in Section 9, the shares to be offered under the Plan shall consist of Common Stock of the Company, and the total number of shares of Common Stock that may be awarded under the Plan shall not exceed 600,000 ~~500,000~~ shares. The shares awarded under the Plan may be authorized and unissued shares, reacquired shares or shares purchased on the open market for delivery to participants. If a Performance-based Award granted under the Plan expires, terminates or is cancelled, the shares subject to such Performance-based Award shall again be available under the Plan. If shares sold or awarded as a bonus or Performance-based Award under the Plan are forfeited to the Company or repurchased by the Company, the number of shares forfeited or repurchased shall again be available under the Plan.

3. Effective Date and Duration of Plan.

(a) Effective Date. The Plan shall become effective as of January 1, 2001. However, all awards under the Plan shall be conditioned on and subject to approval of the Plan by the shareholders of the Company. Subject to this limitation, Performance-based Awards may be granted and shares may be awarded as bonuses or sold under the Plan at any time after the effective date and before termination of the Plan.

(b) Duration. The Plan shall continue in effect until all shares available for award under the Plan have been delivered to participants and all restrictions on such shares have lapsed. The Board of Directors may suspend or terminate the Plan at any time except with respect to Performance-based Awards and shares subject to restrictions then outstanding under the Plan. Termination shall not affect any right of the Company to repurchase shares or the forfeitability of shares awarded under the Plan.

4. Administration.

(a) Board of Directors. The Plan shall be administered by the Board of Directors of the Company, which shall determine and designate from time to time the individuals to whom awards shall be made, the amount of the awards and the other terms and conditions of the awards. Subject to the provisions of the Plan, the Board of Directors may from time to time adopt and amend rules and regulations relating to administration of the Plan, advance the lapse of any waiting period, accelerate any exercise date, waive or modify any restriction applicable to shares (except those restrictions imposed by law) and make all other determinations in the judgment of the Board of Directors necessary or desirable for the administration of the Plan. The interpretation and construction of the provisions of the Plan and related agreements by the Board of Directors shall be final and conclusive. The Board of Directors may correct any defect or supply any omission or reconcile any inconsistency in the Plan or in any related agreement in the manner and to the extent it shall deem expedient to carry the Plan into effect, and it shall be the sole and final judge of such expediency.

¹	Double-underlined matter is new; matter crossed out is proposed to be deleted.

A-1

(b) Committee. The Board of Directors may delegate to a committee of the Board of Directors or specified officers of the Company, or both (the “Committee”) any or all authority for administration of the Plan. If authority is delegated to a Committee, all references to the Board of Directors in the Plan shall mean and relate to the Committee except (i) as otherwise provided by the Board of Directors, and (ii) that only the Board of Directors may amend or terminate the Plan as provided in Sections 3 and 10.

5. Types of Awards; Eligibility. The Board of Directors may, from time to time, take the following action, separately or in combination, under the Plan: (i) award stock bonuses as provided in Section 6; (ii) sell shares subject to restrictions as provided in Section 7; and (iii) grant Performance-based Awards as provided in Section 8. An award may be made to any employee, officer or director of the Company or any subsidiary of the Company. The Board of Directors shall select the individuals to whom awards shall be made and shall specify the action taken with respect to each individual to whom an award is made. At the discretion of the Board of Directors, an individual may be given an election to surrender an award in exchange for the grant of a new award.

6. Stock Bonuses. The Board of Directors may award shares under the Plan as stock bonuses. Shares awarded as a bonus shall be subject to the terms, conditions and restrictions determined by the Board of Directors. The restrictions may include restrictions concerning transferability and forfeiture of the shares awarded, together with any other restrictions determined by the Board of Directors. The Board of Directors may require the recipient to sign an agreement as a condition of the award, but may not require the recipient to pay any monetary consideration other than amounts necessary to satisfy tax withholding requirements. The agreement may contain any terms, conditions, restrictions, representations and warranties required by the Board of Directors. The certificates representing the shares awarded shall bear any legends required by the Board of Directors. The Company may require any recipient of a stock bonus to pay to the Company in cash or by check upon demand amounts necessary to satisfy any applicable federal, state or local tax withholding requirements. If the recipient fails to pay the amount demanded, the Company may withhold that amount from other amounts payable to the recipient, including salary, subject to applicable law. With the consent of the Board of Directors, a recipient may satisfy this obligation, in whole or in part, by instructing the Company to withhold from any shares to be received or by delivering to the Company other shares of Common Stock; provided, however, that the number of shares so withheld or delivered shall not exceed the minimum amount necessary to satisfy the required withholding obligation. Upon the payment of a stock bonus, the number of shares reserved for award under the Plan shall be reduced by the number of shares paid as a bonus, less the number of shares withheld or delivered to satisfy withholding obligations.

7. Restricted Stock. The Board of Directors may sell shares under the Plan for any consideration (including promissory notes and services) determined by the Board of Directors. Shares sold under the Plan shall be subject to the terms, conditions and restrictions determined by the Board of Directors. The restrictions may include restrictions concerning transferability, repurchase by the Company and forfeiture of the shares sold, together with any other restrictions determined by the Board of Directors. All Common Stock sold pursuant to this Section 7 shall be subject to a purchase agreement, which shall be executed by the Company and the prospective purchaser of the shares before the delivery of certificates representing the shares to the purchaser. The purchase agreement may contain any terms, conditions, restrictions, representations and warranties required by the Board of Directors. The certificates representing the shares shall bear any legends required by the Board of Directors. The Company may require any purchaser of restricted stock to pay to the Company in cash or by check upon demand amounts necessary to satisfy any applicable federal, state or

A-2

local tax withholding requirements. If the purchaser fails to pay the amount demanded, the Company may withhold that amount from other amounts payable to the purchaser, including salary, subject to applicable law. With the consent of the Board of Directors, a purchaser may satisfy this obligation, in whole or in part, by instructing the Company to withhold from any shares to be received or by delivering to the Company other shares of Common Stock; provided, however, that the number of shares so withheld or delivered shall not exceed the minimum amount necessary to satisfy the required withholding obligation. Upon the sale of restricted stock, the number of shares reserved for award under the Plan shall be reduced by the number of shares sold, less the number of shares withheld or delivered to satisfy withholding obligations.

8. Performance-based Awards. The Board of Directors may grant awards intended to qualify as qualified performance-based compensation under Section 162(m) of the Internal Revenue Code of 1986, as amended, and the regulations thereunder (“Performance-based Awards”). Performance-based Awards shall be denominated at the time of grant either in Common Stock (“Stock Performance Awards”) or in dollar amounts (“Dollar Performance Awards”). Payment under a Stock Performance Award or a Dollar Performance Award shall be made, at the discretion of the Board of Directors, in Common Stock (“Performance Shares”), or in cash or in any combination thereof. Performance-based Awards shall be subject to the following terms and conditions:

(a) Award Period. The Board of Directors shall determine the period of time for which a Performance-based Award is made (the “Award Period”).

(b) Performance Goals and Payment. The Board of Directors shall establish in writing objectives (“Performance Goals”) that must be met by the Company or any subsidiary, division or other unit of the Company (“Business Unit”) during the Award Period as a condition to payment being made under the Performance-based Award. The Performance Goals for each award shall be one or more targeted levels of performance with respect to one or more of the following objective measures with respect to the Company or any Business Unit: earnings, earnings per share, stock price increase, total shareholder return (stock price increase plus dividends), return on equity, return on assets, return on capital, economic value added, revenues, operating income, inventories, inventory turns, cash flows or any of the foregoing before the effect of acquisitions, divestitures, accounting changes, and restructuring and special charges (determined according to criteria established by the Board of Directors). The Board of Directors shall also establish the number of Performance Shares or the amount of cash payment to be made under a Performance-based Award if the Performance Goals are met or exceeded, including the fixing of a maximum payment (subject to Section 8(d)). The Board of Directors may establish other restrictions to payment under a Performance-based Award, such as a continued employment requirement, in addition to satisfaction of the Performance Goals. Some or all of the Performance Shares may be delivered to the participant at the time of the award as restricted shares subject to forfeiture in whole or in part if Performance Goals or, if applicable, other restrictions are not satisfied.

(c) Computation of Payment. During or after an Award Period, the performance of the Company or Business Unit, as applicable, during the period shall be measured against the Performance Goals. If the Performance Goals are not met, no payment shall be made under a Performance-based Award. If the Performance Goals are met or exceeded, the Board of Directors shall certify that fact in writing and certify the number of Performance Shares earned or the amount of cash payment to be made under the terms of the Performance-based Award.

A-3

(d) Maximum Awards. No participant may receive in any fiscal year Stock Performance Awards under which the aggregate amount payable under the Awards exceeds the equivalent of 50,000 shares of Common Stock or Dollar Performance Awards under which the aggregate amount payable under the Awards exceeds $1,000,000.

(e) Tax Withholding. Each participant who has received Performance Shares shall, upon notification of the amount due, pay to the Company in cash or by check amounts necessary to satisfy any applicable federal, state and local tax withholding requirements. If the participant fails to pay the amount demanded, the Company or the Employer may withhold that amount from other amounts payable to the participant, including salary, subject to applicable law. With the consent of the Board of Directors, a participant may satisfy this obligation, in whole or in part, by instructing the Company to withhold from any shares to be received or by delivering to the Company other shares of Common Stock; provided, however, that the number of shares so delivered or withheld shall not exceed the minimum amount necessary to satisfy the required withholding obligation.

(f) Effect on Shares Available. The payment of a Performance-based Award in cash shall not reduce the number of shares of Common Stock reserved for award under the Plan. The number of shares of Common Stock reserved for award under the Plan shall be reduced by the number of shares delivered to the participant upon payment of an award, less the number of shares delivered or withheld to satisfy withholding obligations.

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 Board of Directors in the number and kind of shares available for grants under the Plan. In addition, the Board of Directors shall make appropriate adjustment in the number and kind of shares subject to outstanding Performance-based Awards so that the recipient’s proportionate interest before and after the occurrence of the event is maintained. Notwithstanding the foregoing, the Board of Directors shall have no obligation to effect any adjustment that would or might result in the award of fractional shares, and any fractional shares resulting from any adjustment may be disregarded or provided for in any manner determined by the Board of Directors. Any such adjustments made by the Board of Directors shall be conclusive.

10. Amendment of Plan. The Board of Directors may at any time, and from time to time, modify or amend the Plan in such respects as it shall deem advisable because of changes in the law while the Plan is in effect or for any other reason. Except as provided in Section 9, however, no change in an award already granted shall be made without the written consent of the holder of such award.

11. Approvals. The issuance by the Company of authorized and unissued shares or reacquired shares under the Plan 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 participants in satisfaction of awards under the Plan. The obligations of the Company under the Plan 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 grants under the Plan. The foregoing notwithstanding, the

A-4

Company shall not be obligated to issue or deliver Common Stock under the Plan if such issuance or delivery would violate applicable state or federal securities laws.

12. Employment and Service Rights. Nothing in the Plan or any award pursuant to the Plan shall (i) confer upon any employee any right to be continued in the employment of the Company or any subsidiary or interfere in any way with the right of the Company or any subsidiary by whom such employee is employed to terminate such employee’s employment at any time, for any reason, with or without cause, or to decrease such employee’s compensation or benefits, or (ii) confer upon any person engaged by the Company any right to be retained or employed by the Company or to the continuation, extension, renewal, or modification of any compensation, contract, or arrangement with or by the Company.

13. Rights as a Shareholder. The recipient of any award under the Plan shall have no rights as a shareholder with respect to any Common Stock until the date the recipient becomes the holder of record of those shares. Except as otherwise expressly provided in the Plan, no adjustment shall be made for dividends or other rights for which the record date occurs prior to the date the recipient becomes the holder of record.
