INTRODUCTION

What is the purpose of this proxy statement?

This proxy statement relates to Grainger's 2008 annual meeting of shareholders to be held on April 30, 2008, and any adjournment of that meeting. It contains information intended to help you make your voting decisions. We are sending the proxy statement to you because Grainger's Board of Directors is soliciting your proxy to vote your shares at the meeting. The mailing of the proxy statement and other proxy-soliciting materials to you and other shareholders began on or about March 14, 2008.

What matters are scheduled to be presented?

The election of thirteen directors. A proposal to ratify the appointment of Ernst & Young LLP as Grainger's independent auditor for the year ending December 31, 2008.

Who is entitled to vote?

Holders of shares of common stock outstanding on Grainger's books at the close of business on March 3, 2008, the record date for the meeting, may vote. There were 77,447,168 shares of common stock outstanding at that time.

How many votes do I have?

You have the right to cumulative voting in the election of directors. This means that you have a number of votes in the election equal to the number of shares you own multiplied by the number of directors being elected. You can cast those votes for the nominees as you choose. For example, you may cast all your votes for one nominee or you may apportion your votes among two or more nominees.

In any matter other than the election of directors, each of your shares is entitled to one vote.

Does Grainger have majority voting for election of directors?

Yes. Directors are elected by the votes of a majority of the shares represented in person or by proxy at the meeting and entitled to vote.

What if I don't indicate my voting choices?

If Grainger receives your proxy in time to permit its use at the meeting, your shares will be voted in accordance with the instructions you indicate. If we have received your proxy and you have not indicated otherwise, your shares will be voted as recommended by Grainger's Board. Specifically, your shares will be voted, either individually or cumulatively, FOR the election of the director nominees and FOR the proposal to ratify the appointment of the independent auditor.

How does discretionary voting apply?

Grainger is not aware of any matter not described in this proxy statement that will be presented for consideration at the meeting. If another matter is properly presented, your shares will be voted on the matter in accordance with the judgment of the person or persons voting the proxy unless your proxy withholds discretionary authority.

ZEQ.=1,SEQ=6,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=303896,FOLIO='1',FILE='DISK126:[08ZAH1.08ZAH15401]DE15401A.;14',USER='GLOPEZA',CD=';5-MAR-2008;17:02'

May I revoke my proxy?

You may revoke your proxy at any time before the voting at the meeting. You can do so in one of the following ways:

What does it mean if I receive more than one set of proxy materials?

Receiving multiple sets of proxy-soliciting materials generally means that your Grainger shares are held in different names or in different accounts. You must vote all of the proxy requests to ensure that all your shares are voted.

What constitutes a quorum at the meeting?

A majority of the outstanding shares entitled to vote on a matter, whether present in person or by proxy, constitutes a quorum for consideration of that matter at the meeting. A quorum is necessary for valid action to be taken on the matter. Your shares will be present by proxy and count toward the quorum if you give us your proxy by telephone, by Internet, or by signing, dating, and returning a proxy form.

Who pays the costs of soliciting proxies?

Grainger will pay all the costs of soliciting management proxies. Brokerage firms, custodians, nominees, fiduciaries, and other intermediaries are being asked to forward the proxy-soliciting materials to beneficial owners of Grainger common stock and to obtain their authority to give proxies. Grainger will reimburse these intermediaries for their reasonable expenses.

In addition to mailing proxy-soliciting materials, Grainger's directors, officers, and regular employees may solicit proxies personally, by telephone, or by other means. They will not receive additional compensation for these services, other than normal overtime pay, if applicable. Representatives of Grainger's transfer agent may also solicit proxies. Grainger additionally has employed D.F. King & Co., Inc. to help solicit proxies and will pay that firm approximately $6,500 for its services, plus reasonable costs and expenses.

How do I submit a shareholder proposal or directly nominate a director at the 2009 annual meeting?

If you wish to have a shareholder proposal included in Grainger's proxy-soliciting materials for the 2009 annual meeting of shareholders, please send a notice of intent to submit your proposal at that meeting to the Corporate Secretary at Grainger's headquarters. The notice, including the text of the proposal, must be in writing, signed, and in compliance with the timing and other requirements of the proxy rules of the Securities and Exchange Commission. For a shareholder proposal relating to the 2009 annual meeting to be timely, Grainger must receive the notice no later than November 14, 2008.

Grainger's by-laws require written notice concerning a shareholder submission of a proposal or a shareholder nomination of a person for election as a director at a meeting of shareholders. For a

ZEQ.=2,SEQ=7,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=934499,FOLIO='2',FILE='DISK126:[08ZAH1.08ZAH15401]DE15401A.;14',USER='GLOPEZA',CD=';5-MAR-2008;17:02'

shareholder proposal, certain information about the shareholder and the proposal is required. For the submission of a proposal, the notice must be furnished generally not less than 90 days and not more than 120 days before the anniversary date of the prior year's annual meeting. Likewise, for a shareholder nomination, certain information about the shareholder and the nominee is required. For a nomination to be considered at Grainger's 2009 annual meeting, the notice must be furnished no later than November 14, 2008.

A copy of the by-laws are available in the Corporate Governance section of Grainger's Web site at www.grainger.com/investor or may be obtained free of charge on written request to the Corporate Secretary at Grainger's headquarters, 100 Grainger Parkway, Lake Forest, Illinois 60045.

ZEQ.=3,SEQ=8,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=230936,FOLIO='3',FILE='DISK126:[08ZAH1.08ZAH15401]DE15401A.;14',USER='GLOPEZA',CD=';5-MAR-2008;17:02'

ELECTION OF DIRECTORS

Grainger's directors are elected each year at the annual meeting. As set forth in the Operating Principles for the Board of Directors, Grainger expects all directors and nominees to attend annual meetings. At the 2007 annual meeting, all of the directors were in attendance.

Thirteen directors are nominated for election at this year's annual meeting. All directors are elected for a one-year term. The directors will therefore serve until the 2009 annual meeting of shareholders or until their successors have been qualified and elected.

Majority (rather than plurality) voting applies to Grainger's director elections. Accordingly, directors are elected by the votes of a majority of the shares of Grainger common stock represented in person or by proxy at the meeting and entitled to vote. A shareholder directing to withhold authority for re-election of directors will have the same effect as votes against the election of directors. Broker non-votes will not affect the outcome of the vote.

If any of the nominees for director mentioned below should be unavailable for election, a circumstance that is not expected, the person or persons voting your proxy may exercise discretion to vote for a substitute nominee selected by the Board.

The Board has adopted "categorical standards" to assist it in evaluating the independence of nominees. The categorical standards are intended to help the Board in determining whether certain relationships between nominees and Grainger are "material relationships" for purposes of the New York Stock Exchange (NYSE) independence standards. The categorical standards adopted by the Board are consistent with, and in some respects more strict in their requirements than, the NYSE's "bright line" independence criteria. The categorical standards adopted by the Board are set forth in Appendix A to this proxy statement and are also available in the Corporate Governance section of Grainger's Web site at www.grainger.com/investor.

In the ordinary course of its operations during 2007, Grainger engaged in various types of transactions with organizations with which Grainger directors are associated in their principal business occupations or otherwise. Specifically, in the ordinary course of its business during 2007, Grainger bought products and/or services from, or sold products and/or services to, companies with which Messrs. Hall, Levenick, McCarter, and Slavik are associated as executive officers or otherwise. In no instance did the total amount of the purchases from or sales to such a company during 2007 represent more than 0.38% of the projected consolidated gross revenues of that company for the year or 0.08% of the consolidated gross revenues of Grainger for the year. In addition, as part of its overall 2007 charitable contributions program, Grainger made donations to tax-exempt organizations with which Messrs. Anderson, Gantz, Hall, McCarter, Novich, and Smith serve as officers, directors or trustees. In no instance did the total amount of the contributions to such an organization during 2007 represent more than 0.20% of that organization's projected total contributions for the year. The Board considered these transactions and donations in assessing the independence of the directors involved against the NYSE's independence standards and Grainger's categorical standards, and determined that none of the directors had any direct or material indirect interest in the transactions and donations. Similar transactions and donations are likely to occur in the future, and are not expected to impair the independence of the directors involved.

The Board has determined that each of Messrs. Anderson, Gantz, Hall, Levenick, McCarter, Novich, Roberts, Rogers, Slavik, and Smith and Ms. Hailey has no material relationship with Grainger within the meaning of the NYSE independence standards and Grainger's categorical standards. The

ZEQ.=4,SEQ=9,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=696996,FOLIO='4',FILE='DISK126:[08ZAH1.08ZAH15401]DE15401A.;14',USER='GLOPEZA',CD=';5-MAR-2008;17:02'

other nominees, Messrs. Keyser and Ryan, are Grainger employees and, accordingly, are not considered "independent." All of the nominees were previously elected by the shareholders. The nominees have provided the following information about themselves, including their ages in March 2008. Unless otherwise indicated, each has served for at least the past five years in the principal business position currently or most recently held.

BOARD OF DIRECTORS AND BOARD COMMITTEES

Five meetings of the Board were held in 2007. Each Board meeting included at least one executive session, during which only independent directors were present. In addition, the directors acted twice by unanimous consent during the year.

The Board has three standing committees: Audit, Board Affairs and Nominating, and Compensation. All members of these committees are required to be "independent" directors. All non-employee directors have been determined to be independent. Committee memberships are shown in the following table:

Each non-employee director of Grainger is an alternate member of each Board committee of which the director has not been specifically appointed a member. An alternate committee member may serve for all purposes at a committee meeting in place of a regular member who is absent.

Audit Committee

The Audit Committee met four times in 2007. The Board has determined that each of the members of the Audit Committee is "independent," as that term is defined in the independence requirements for audit committee members contained in the applicable rules of the Securities and Exchange Commission (SEC) and standards of the New York Stock Exchange (NYSE). The Board has also determined that each of Mr. Brian P. Anderson, Chairman of the Audit Committee, and Ms. V. Ann Hailey, a member of the Audit Committee, is an "audit committee financial expert," as that term is defined in the applicable rules of the SEC.

The Audit Committee assists the Board in its oversight responsibility with respect to Grainger's financial reporting process, Grainger's systems of internal accounting and financial controls, the

integrity of Grainger's financial statements, Grainger's compliance with legal and regulatory requirements, the qualifications and independence of Grainger's independent auditors, and the performance of Grainger's internal audit function and independent auditors. It also has oversight responsibilities for various aspects of certain employee benefit plans. Additionally included among the responsibilities of the Audit Committee are the appointment, compensation, retention, and oversight of the independent auditors, the establishment of procedures for the treatment of complaints regarding accounting, internal accounting controls, and auditing matters, and the pre-approval of audit and non-audit services to be provided by the independent auditors. The Audit Committee has the further responsibility of overseeing compliance with Grainger's Business Conduct Guidelines.

Board Affairs and Nominating Committee

The Board Affairs and Nominating Committee met three times in 2007. The Board has determined that each of the members of the Board Affairs and Nominating Committee is "independent," as that term is defined in the independence requirements for members of nominating committees contained in the applicable standards of the NYSE. The Chairman of the Board Affairs and Nominating Committee (currently, John W. McCarter, Jr.) reviews in advance of meetings all agendas of Board meetings and acts as Chairman and presides at regular executive sessions of the Board without management participation.

The Board Affairs and Nominating Committee makes recommendations to the Board regarding the makeup of the Board and its committees, establishes specific criteria by which potential directors shall be qualified, identifies potential nominees, makes recommendations concerning director and nominee independence, reviews transactions between Grainger and related persons (as further discussed below) as well as evaluates the overall performance of the Board. It also has primary responsibility for corporate governance oversight, including the responsibility to recommend corporate governance principles, recommend Board committee responsibilities and members, evaluate the Board in the area of corporate governance, including the adequacy of the information supplied to the Board and the Board's performance of its oversight responsibilities relative to the management of Grainger, and to recommend retirement, compensation, and other policies applicable to directors. Additional responsibilities are to review senior management organization and succession and to make initial assessments regarding major issues or proposals.

Compensation Committee

The Compensation Committee oversees Grainger's activities in the area of compensation and benefits (generally with regard to all employees and specifically with regard to officers) and reviews and makes recommendations concerning compensation-related matters to be submitted to the Board and/or shareholders for approval. The general responsibilities of the Committee are to ensure:

That a market competitive compensation structure is in place that will attract, motivate, and retain key talent necessary to help deliver performance that will increase shareholder value; That compensation and benefit policies and practices reflect the highest level of integrity; That compensation, especially senior management compensation, is linked to performance, both personal and Company; and The appropriate administration of various stock and incentive plans.

In 2007, the Compensation Committee met six times. Each meeting included an executive session without management present. The Board has determined that each of the members of the Compensation Committee is "independent," as that term is defined in the independence requirements for members of compensation committees contained in the applicable standards of the NYSE.

The Compensation Committee annually reviews and approves corporate goals and objectives, including financial performance measures relevant to chief executive officer compensation, evaluates the chief executive officer's performance in light of those goals and objectives, and, either as a committee or together with the other independent directors as directed by the Board, determines and approves the chief executive officer's compensation level based on this evaluation.

In establishing Grainger's compensation systems, the Compensation Committee develops programs based on its own deliberations, as well as considers alternatives and recommendations from its own independent consultant, a variety of other compensation and benefits consultants, and management. Since 2004, the Committee has retained Deloitte Consulting LLP (Deloitte) as its independent compensation consultant. The independent compensation consultant is solely hired by and reports directly to the Committee, and it is the Committee's practice to routinely meet privately with the independent consultant in executive session. The Committee has sole authority to retain and terminate the independent consultant, including sole authority to approve the consultant's fees. The independent compensation consultant:

attends Committee meetings; assists the Committee in evaluating compensation proposals; helps analyze recommendations proposed by management; responds to specific compensation-related inquiries; and undertakes special projects as instructed by the Committee.

The Committee seeks advice from the independent consultant on compensation trends and best practices, as well as in reviewing Grainger's plans to ensure they are designed and operate to achieve their purposes and goals. During 2007, the independent consultant performed a number of specific projects including an analysis of executive compensation trends incorporating alternative ways to view executive compensation and an analysis and competitive market valuation for director compensation, as well as provided advice on executive compensation disclosure requirements and trends. In 2007, the independent consultant attended all Compensation Committee meetings as well as the executive sessions without management present.

Deloitte provides other services to Grainger that are unrelated to executive compensation matters. The Committee believes that the scope and nature of these services do not impair the independence of its advisor.

Members of management (including certain of its "Named Executive Officers," or NEOs, as that term is further described below) assist the Compensation Committee in performing its responsibilities by providing recommendations for the Committee's consideration concerning the design of Grainger's compensation program for its NEOs, other officers, and other employees. Management also recommends award levels, except those related to Messrs. Keyser and Ryan, which are reviewed by the Compensation Committee and then determined by the independent members of the Board in executive session without members of management present.

The Compensation Committee grants equity awards (stock options, restricted stock units (RSUs), and performance shares) to elected officers and other employees under the 2005 Incentive Plan. The Committee delegates to management a limited authority to grant stock options and RSUs to employees. Awards under this authority are granted using features and agreements that have been approved by the Committee. The pool of shares available to management is refreshed annually to 50,000 options and 25,000 RSUs. The maximum amount that management can award to any employee is 5,000 stock options and 2,500 RSUs. The awards are effective the first business day of the month following the month in which the grant was approved by management. Information concerning the grants is shared with the Committee at its next meeting following the grant. The delegation of authority may be terminated by the Committee at its discretion.

DIRECTOR COMPENSATION

The 11 independent directors are compensated at a level that approximates median market practice for an appropriate compensation comparator group, as confirmed by the Compensation Committee's independent compensation consultant. Grainger pays these directors an annual retainer of $60,000 for the year beginning with the annual meeting of shareholders, which is intended to cover all regularly scheduled meetings of the Board and its committees. If additional meetings are held, a per-meeting fee of $1,500 is paid to each attending director. A director who is an employee of Grainger or any Grainger subsidiary does not receive any compensation for serving as a director.

The Chairmen of Board committees receive annual retainers. For the Chairman of the Audit Committee, the annual retainer is $10,000; for the Chairman of the Board Affairs and Nominating Committee and the Chairman of the Compensation Committee, the retainer is $7,500. Other directors receive an annual retainer of $5,000 for each committee on which they serve as a member. Directors may elect to defer, in a deferred stock unit account, their chair and committee retainers as well as the annual retainers and meeting fees described in the preceding paragraph.

In addition, directors receive an annual deferred stock unit grant. The number of shares covered by each grant is equal to $60,000 divided by the fair market value of a share of Grainger common stock at the time of grant, rounded up to the next ten-share increment. The deferred stock units are settled on termination of service as a director. Grainger provides travel and reimburses travel expenses relating to service as a director and reimburses directors for attending continuing education programs. In addition, Grainger matches directors' charitable contributions and provides discounts on product purchases on the same basis as Grainger employees.

The directors' compensation will be increased at the 2008 Annual Meeting of Shareholders so that the annual retainer will be $70,000 and the deferred stock grant will equal $100,000. The annual retainer for the Audit Committee Chair will remain $10,000. The annual retainers for the other committee Chairs will be reduced to $5,000. There will no longer be annual retainers for committee members.

Stock ownership guidelines applicable to non-employee directors were established in 1998. These guidelines provide that within five years after election, a director must own Grainger common

OWNERSHIP OF GRAINGER STOCK

The table below shows how many shares of Grainger common stock the directors, the nominees, certain executive officers, and all directors and executive officers as a group beneficially owned as of March 3, 2008.

Beneficial ownership is a term broadly defined by the SEC. In general, a person beneficially owns securities if the person, alone or with another, has voting power or investment power (the power to sell) over the securities. Being able to acquire either voting or investment power within 60 days, such as by exercising stock options, also results in beneficial ownership of securities. Unless otherwise indicated in the footnotes following the table, each of the named persons had beneficial ownership of the indicated number of Grainger shares by sole voting and investment power.

REPORT OF THE AUDIT COMMITTEE OF THE BOARD

The Audit Committee of the Board of Directors assists the Board in fulfilling its oversight responsibilities. The Board has determined that each of the members of the Audit Committee is "independent," as that term is defined in the independence requirements for audit committee members contained in the applicable rules of the Securities and Exchange Commission and standards of the New York Stock Exchange. The Audit Committee acts under a charter that was last amended by the Board on February 20, 2008, and is available on the Company's website at www.grainger.com/investor.

Management is responsible for the Company's internal controls and the financial reporting process. Ernst & Young LLP, the Company's independent auditor, was responsible for performing an independent audit of the Company's most recent consolidated financial statements and expressing an opinion on the conformity of those financial statements with accounting principles generally accepted in the United States of America, as well as expressing an opinion on (i) management's assessment of the effectiveness of internal control over financial reporting and (ii) the effectiveness of the Company's internal control over financial reporting. The Audit Committee's responsibility is to monitor and oversee these processes.

In performing these responsibilities, the Audit Committee reviewed and discussed the Company's audited consolidated financial statements and the effectiveness of internal control over financial reporting with management and Ernst & Young LLP. The Audit Committee discussed with Ernst & Young LLP matters required to be discussed by Statement on Auditing Standards No. 61, "Communication with Audit Committees," and Public Company Accounting Oversight Board (PCAOB) Auditing Standard No. 5, "An Audit of Internal Control Over Financial Reporting Performed in Conjunction with An Audit of Financial Statements." Ernst & Young LLP also provided to the Audit Committee the letter and written disclosures required by Independence Standards Board Standard No. 1, "Independence Discussions with Audit Committees," and the Audit Committee discussed with Ernst & Young LLP the matter of the firm's independence.

Based on the review and discussions described above, the Audit Committee recommended to the Board of Directors that the audited financial statements be included in the Company's Annual Report on Form 10-K for the year ended December 31, 2007, as filed with the Securities and Exchange Commission.

COMPENSATION DISCUSSION AND ANALYSIS

This Compensation Discussion and Analysis discusses the Company's compensation policies and arrangements that are applicable to the Named Executive Officers (NEOs) appearing in the Summary Compensation Table (which follows below) for fiscal year 2007.

Overview of the Compensation Program

The Company's compensation program for its NEOs builds upon a philosophy that is applied to all Company employeesattract the best people and encourage them to achieve the results that create shareholder value. The Company uses its compensation systems to attract, reward, and retain its employees and to motivate them to grow the business profitably. By aligning compensation with growth and return on capital, the Company has linked its incentives with increases in shareholder return.

Demonstrating the Company's long-standing commitment to this compensation philosophy is the Profit Sharing Trust (PST). All U.S.-based employees participate in the PST as their sole Company-sponsored retirement vehicle. The PST aligns the interests of the Company's employees, management, and shareholders. The Company's annual contribution to the PST is based on a formula that incorporates two key drivers of shareholder valueearnings performance and capital employed. Employees share in the success of the Company only if the business is profitable and only after a threshold return has been provided on invested capital. The contribution percentage that each participating employee receives is a function of his or her years of service. The maximum contribution occurs at five or more years of service. The Company's NEOs participate in the PST on the same basis as all other employees.

The compensation program for NEOs consists of base salary, annual cash incentive, long-term incentives, benefits, and perquisites. It is designed, as a whole, to attract, reward, motivate, and retain high-quality executive and managerial talent and to provide appropriate cash- and equity-based incentives for achieving the Company's business goals and strategic objectives. A substantial portion of the executives' pay is directly tied to Company performance. The Company endeavors to accomplish the compensation program's objectives by providing total compensation opportunities at target levels of performance at the median of the market.

An NEO's compensation includes variable pay components that link a substantial portion of compensation to the Company's performance, the individual's functional and managerial responsibilities and performance, and the creation of long-term shareholder value. These variable components include annual cash incentives and long-term equity-based incentives. Variable compensation, as a percentage of total compensation, generally increases with greater levels of responsibility within the Company. Compensation for the NEOs is generally structured so that the largest component is long-term equity, followed by base salaries, and short-term incentive plan compensation. In exercising its judgment in setting the components of total compensation, the Compensation Committee of the Board (Committee) considers competitive pay data but has not established a rigid formula or allocation.

In setting individual compensation levels, the Committee selects a compensation comparator group of companies and reviews studies of total compensation paid to executives occupying similar positions in those companies. The Committee then considers a variety of reference points, including competitive compensation data at the 25 th , 50 th , and 75 th percentiles, the executive's overall experience, individual and Company performance, replaceability, internal equity, and unique skills in

ZEQ.=2,SEQ=27,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=206572,FOLIO='22',FILE='DISK126:[08ZAH1.08ZAH15401]DM15401A.;46',USER='GLOPEZA',CD=';5-MAR-2008;19:43'

determining an appropriate level of compensation for each individual executive. All elements of compensation are valued and reviewed in evaluating the relative competitiveness of the Company's compensation practices against the comparator group. Target total compensation for the Company is generally set to approximate the market median.

In addition, the Committee annually reviews a tally sheet for each NEO, which includes the current base salary, annual incentive award, and the value of all outstanding equity-based awards, deferrals, benefits, and perquisites, as well as potential payments under retirement and certain change in control situations. The Committee uses the tally sheets to help it understand the value of all compensation (both vested and unvested) that may be due an NEO. Since the NEOs do not have employment contracts with the Company that guarantee continued employment, the tally sheets also facilitate the Committee's evaluation of the reasonableness of awards and their likely retentive impact. The Committee did not make specific adjustments to the compensation program based on its review of the tally sheets, as it concluded the awards earned or provided on termination were consistent with the Committee's pay philosophy, Company and individual performance, and market practices.

The other components of the Company's compensation program for NEOs are substantially similar to the program available for most of the Company's managers. This includes the same health and welfare benefits as well as the same methodology for determining the percentage contribution in the PST. The Company maintains supplemental retirement plans only to the extent necessary to provide all employees with profit sharing benefits commensurate with current compensation and unaffected by limitations imposed by tax law.

Role of Management

A committee of management, including the CEO, the President, the CFO, the General Counsel, and the Senior Vice President, Human Resources, routinely recommends compensation and performance-incentive programs that it believes will provide the appropriate level of incentives to achieve the Company's compensation goals: attract the best people and encourage them to achieve results that create shareholder value. The recommendations also include the structure of short- and long-term incentive programs for all employees and changes to programs required for regulatory compliance. These recommendations are reviewed and approved by the CEO before they are presented to the Compensation Committee of the Board.

Consistent with this process and the factors discussed above, management works with advisors from Hewitt Associates LLC (Hewitt) to develop market information and recommends base salaries and adjustments, annual incentive targets, and long-term incentive awards to the Committee for officers including the NEOs other than Messrs. Keyser and Ryan. The compensation awarded to Messrs. Keyser and Ryan is considered by the Committee and, following the Committee's recommendation, is then determined by the independent members of the Board in executive session without members of management present. Management also develops the annual and long-term incentive targets for the year for approval by the Committee. The Committee reviews these recommendations in conjunction with its independent compensation consultant.

Compensation Comparator Group

The compensation comparator group is derived from a database maintained by Hewitt that contains detailed company-specific compensation data. Every other year, the Committee commissions a comparator group study from Hewitt, which it then reviews with Hewitt and the Committee's independent compensation consultant (Deloitte). The most recent comparator group study was

ZEQ.=3,SEQ=28,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=578639,FOLIO='23',FILE='DISK126:[08ZAH1.08ZAH15401]DM15401A.;46',USER='GLOPEZA',CD=';5-MAR-2008;19:43'

performed in 2006 (2006 Compensation Study), and the Company expects that a new study will be commissioned in 2008.

In 2006, the comparator group from the previous study was enlarged by five companies and now consists of 22 businesses that are relatively similar in complexity and size (based on 2005 sales and market capitalization) to the Company, and that are representative of the types of major companies with which the Company historically competes for executive talent. This "competitive market" for executive talent includes companies both within and outside the same industry or sector as the Company. Most of the Company's publicly traded direct competitors tend to be too small in sales or scope of operations for direct compensation comparisons with the Company. Including a broader range of companies provides a more representative depiction of the competitive market for talent. Therefore, companies used for compensation comparison purposes differ from those in the industry indicies used in the Company Performance graph in Part II, Item 5 of the Company's most recent Annual Report on Form 10-K. Management has a minimal role in selecting the comparator group. The Committee has relied on Hewitt and Deloitte for input in this area. The primary role of management in determining the comparator group was to provide general comments on the relevance of each industry represented by the comparator companies.

Below is the 2006 Compensation Study comparator group used by the Company, including 2005 sales and market capitalization data used to determine the comparator group. The compensation comparator group is expected to be reevaluated in 2008 using the most currently available data.

Base Salaries

Base salaries are intended to provide an appropriate level of fixed compensation to aid in attraction and retention. Base salaries are determined based on performance, experience, and market. Adjustments to base salaries require a detailed evaluation of individual performance, competitive market levels and rates of increase, executive experience, and internal equity, as well as the Company's overall salary budget. The 2006 Compensation Study showed that, on average, the Company's base salaries for officers were approximately at the market median, although Mr. Keyser, who has been Chief Executive Officer for over 12 years, was 5.9% above the market median. In 2007, Mr. Keyser's base salary was established as $1,170,000, representing a 6.4% increase over 2006. In addition, the Committee approved base salary increases of 6.0% for Mr. Loux, 16.7% for Mr. Ryan (this included a promotional increase), 12.5% for Mr. Chen (this included a promotional increase) and 5.9% for Mr. Howard. These base salary adjustments were made to reflect individual performance, contribution, experience, and to adjust salaries for certain executives to be closer to the market median reflecting their responsibilities. Base salary increases also have the effect of increasing the size of annual incentive and profit sharing opportunities, as both are tied to formulas that are functions of base salary. Base salary increases generally do not impact the long-term equity incentive award opportunities as the Company's long-term award targets are generally tied to organizational positions rather than an individual's base salary.

Annual Incentives

Named Executive Officers (NEOs), along with approximately 1,400 other managers, participate in the Management Incentive Program (MIP), which provides for annual cash incentives based on the achievement of specified annual Company-wide financial performance measures and individual performance. The Company structures the MIP to motivate performance that balances short-term and long-term results and aligns the interests of management with shareholders. The Company believes that the design of the annual incentive program encourages performance that creates shareholder value by focusing on profitable sales growth and return on invested capital (ROIC). For 2007, MIP was based on ROIC, year-over-year sales growth, and the individual executive's performance. ROIC reflects how effectively management uses Company assets and is generally defined by the Company as pre-tax operating earnings divided by net working assets. The total MIP payout is calculated as follows:

MIP Payout = (ROIC Performance × Sales Growth Multiplier) + Individual Performance

This framework was selected as it balances sales growth with profitability, efficiency, expense management, and asset management and encourages achievement of individual objectives. These measures are consistent with the Company's objective of growing profitably over time, which it

ZEQ.=5,SEQ=30,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=31486,FOLIO='25',FILE='DISK126:[08ZAH1.08ZAH15401]DM15401A.;46',USER='GLOPEZA',CD=';5-MAR-2008;19:43'

believes is closely linked with shareholder value creation. The MIP framework allows the Committee the opportunity to annually adjust performance objectives in light of the current economic and competitive environments. The MIP framework also enables the Company to set goals and adjust performance objectives for its individual business units.

The MIP framework has been consistently applied for the past seven years, although specific objectives and target levels have been modified on a year-by-year basis.

The potential payouts for the 2007 MIP range from 0% to 200% of the target award. Actual payout depends upon the Company and individual performance components. The Company performance component has a range of 0% to 170% and is determined by a two-step process:

First, the Company must meet its ROIC threshold. If the Company does not achieve the minimum ROIC threshold (set at 16% for 2007), no Company performance portion can be awarded. If the Company meets or exceeds the ROIC goal (set at 20% for 2007), the employee will have earned an ROIC payout of 50% of his or her MIP target. Amounts are interpolated as necessary. Second, sales growth acts as a multiplier of the ROIC payout. The value of the sales growth multiplier increases as revenue growth increases. If year-over-year sales growth meets the Company's target, the sales multiplier would yield an amount that equals an MIP award of 75% of target. Amounts are interpolated as necessary.

The individual performance component has a range of 0% to 30% of the target award and is determined by achievement of functional and managerial objectives as established at the beginning of the year. Each objective must be connected to activities designed to either grow revenue or impact returns on invested capital. Achievement of the objectives is determined through qualitative as well as quantitative measures.

The Company performance component and the individual performance component are then combined to determine the executive's total MIP payment. Assuming that year-over-year sales growth meets the Company's target and that the individual executive fulfilled all function and managerial objectives, the total MIP award would be 75% + 30% = 105% of the target award.

The 2007 ROIC goal was 20%, which was considered an appropriate long-term level. Exceeding this objective does not create an additional payout, but achieving less than 16% ROIC eliminates the payout associated with both ROIC and sales growth. Over the last ten years, ROIC has ranged from a low of 17.1% in 2000 to a high of 28.5% in 2007. The 2007 sales growth target was 8.0%. Over the last ten years, sales growth has ranged from a low of -4.5% in 2001 to a high of 9.4% in 2005.

The executive's target incentive award under the annual incentive program is based on a review of competitive market practice. For 2007, the target annual incentive awards as a percent of base salary were 110%, 70%, 80%, 70%, and 50% for Messrs. Keyser, Loux, Ryan, Chen, and Howard, respectively. These targets were determined to approximate the market median of the compensation comparator group companies. Actual payments are a product of the executive's incentive target adjusted by the Company's actual results achieved under the financial measures and the assessment of individual performance against specific goals that were established at the beginning of the year. The Company believes that it has set the ROIC and sales growth targets so that together they provide the appropriate level of motivation for participants to grow the Company profitably, which in turn should create shareholder value.

Assessments of the individual performance components were conducted by the NEOs' individual managers, except for Messrs. Keyser and Ryan, each of whose individual performance was assessed by the Committee without management present and then determined by the independent members of the Board in executive session without those officers present. Based on qualitative evaluation, each NEO achieved his individual functional and managerial objectives in 2007, resulting in each receiving a full 30% of their individual performance targets. Each NEO had function-specific goals designed to either grow revenue or impact returns on invested capital that included group objectives and group performance, as well as individual objectives that included implementing the Company's new Enterprise Resource Planning system.

Under the terms of the annual program, the Committee has the discretion to adjust MIP payment amounts to correct for any unusual items or circumstances, both positive and negative, that might affect ROIC or sales growth. No discretionary adjustments were made in 2007.

Incentive amounts were paid to Messrs. Keyser, Loux, and Ryan based on the performance targets established for the 2007 MIP and were made under a separate annual incentive program described in the 2005 Incentive Plan. They were designated as "Covered Employees" under the 2005 Incentive Plan, a separate shareholder-approved plan providing for, among other things, annual incentive programs funded through amounts determined by reference to the Company's reported net earnings. This program is designed to ensure that annual incentives are fully tax deductible by the Company under Section 162(m) of the Internal Revenue Code. Under the program, the Committee allocates to each participant a portion of an incentive pool, which is funded with 5% of the Company's net earnings and the independent members of the Board have the authority to make specific awards. The sum of the individual participants' percentages may not be greater than 100% of the pool. The 5% funding level and predetermined incentive pool allocations were selected to provide the independent members of the Board with sufficient flexibility to calculate an appropriate level of incentives for each executive, while complying with Section 162(m). The independent members of the Board may use their discretion to reduce these amounts but may not increase them. For 2007, the program created a pool of $21 million, of which only $3.1 million or 15% of the total pool was distributed to participants. As it has done in the past, the independent members of the Board used their discretion to reduce amounts to yield payments equal, on a percentage basis, to those made under the 2007 MIP for the other NEOs, coupled with specific individual performance goals.

Based on the amounts of total compensation listed in the Summary Compensation Table (below), annual variable compensation represented from 24% to 31% of total compensation for the NEOs in fiscal year 2007. This is consistent with practices in the Company's compensation comparator group.

Actual results for 2007 were 28.5% ROIC (which is above the MIP target) and 9.1% year-over-year growth in sales (which is below the MIP target). These results translated into annual

ZEQ.=8,SEQ=33,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=74111,FOLIO='28',FILE='DISK126:[08ZAH1.08ZAH15401]DM15401A.;46',USER='GLOPEZA',CD=';5-MAR-2008;19:43'

incentive amounts for 2007 that ranged from 70% to 153% of base salary for the NEOs and represented 139% of the individual target opportunities (including the individual performance component).

The Company will continue to use the same basic MIP framework for 2008, with payouts to be based on Company performance as measured by ROIC and sales growth. Individual performance will no longer be directly reflected in MIP, as the Company believes its sales growth and ROIC goals can be better achieved through providing incentives for performance at an organizational level. The Company will also maintain a focus on individual results through its performance management systems and individual achievement and performance will continue to be considered and rewarded as appropriate by promotions, salary increases, and differentiated equity awards.

Long-Term Incentives

The Company annually provides long-term incentives to NEOs and other key managers in order to:

Achieve specific business goals and objectives (including achieving financial performance that balances growth, profitability, and asset management); Reward management for results that create shareholder value; Attract qualified managers to join the Company; and Retain management through business cycles.

The Company's long-term incentives are stock-based. The target number of shares covered by long-term incentive awards is designed to provide an economic value that is generally at the median of the compensation comparator group for comparable jobs; the target can be adjusted up or down to reflect individual performance. The Committee established the target number of shares at its February 2007 meeting and approved the awards at its April 2007 meeting for all participants, including the NEOs. In connection with their long-term incentive awards, recipients are required to sign an agreement containing confidentiality and non-competition obligations, designed to protect the Company's confidential and proprietary information and to preserve the Company's competitive advantages. Under these agreements, should an executive violate his or her confidentiality or non-compete obligations, any award is automatically forfeited. The agreements also require, in certain circumstances, that an executive who has breached the confidentiality and non-compete agreements must return vested shares and/or gains from disposition of shares to the Company.

The Company's long-term incentives consist of stock options, performance shares, and restricted stock units (RSUs) and are provided under the 2005 Incentive Plan. In 2006, the Company increased the performance component of the long-term incentive program by awarding performance shares to the NEOs and other officers. The performance shares can be earned only if the Company achieves certain objectives described below. The Company seeks to structure awards such that stock options represent approximately 40% of the total value of long-term incentive compensation, RSUs represent approximately 30% of the total value, and performance shares represent approximately 30% of the total value. This mix was chosen to achieve the program objectives noted above. This mix is also reflective of market practices for senior executives, which is to use a combination of awards to provide the desired level of long-term incentives.

40% Stock Options. The Company's stock options provide the right to purchase Company stock at a specified price over a ten-year term and vest 100% on the third anniversary of grant.

ZEQ.=9,SEQ=34,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=1010457,FOLIO='29',FILE='DISK126:[08ZAH1.08ZAH15401]DM15401A.;46',USER='GLOPEZA',CD=';5-MAR-2008;19:43'

30% RSUs. The Company's RSUs are settled in Company stock if the executive is still employed with the Company on the fourth anniversary of the grant. RSUs are intended to increase the retentive qualities of the compensation program through the four-year cliff vesting provision of the awards, to help build stock ownership, and to help meet stock ownership guidelines. The value of the RSUs increases or decreases with changes in the stock price, thus aligning the executives' interests with the shareholders'. Dividend equivalents are paid during the vesting period in order to simulate share ownership. 30% Performance Shares. Performance shares are intended to further align compensation with the Company's business strategy and the long-term creation of shareholder value. The Company's performance shares provide the executive with a range of potential share payouts in three years only if specified performance criteria are met. The actual number of earned shares can range from 0% to 200% of the target number of shares, depending on one-year sales growth and continued ROIC achievement over three years.

The three-year performance cycle for the performance shares begins on January 1 of each year. The number of shares that could have been earned for the 2007 grant of performance shares ranged from 0% to 200% of the target award, depending on the Company's year-over-year growth in sales. The 2007 performance share program was structured as follows:

end of user-specified TAGGED TABLE (1) Amounts are interpolated, as necessary. (2) Vesting is contingent upon the achievement of a 3-year average 18% ROIC threshold.

If, during 2007, the Company had achieved less than 5 percent sales growth, 0% of the target award would be available, 5 percent growth would have yielded 50% of the target award, 8 percent growth would have yielded 100%, and 11% growth would have yielded 200%. Given actual sales growth performance of 9.1%, the number of shares determined for the NEOs for 2007 was 137% of target. These shares will vest at the end of fiscal year 2009 only if the average ROIC performance over the three-year period from 2007 through 2009 is greater than or equal to 18%. The Committee selected these measures as they balance sales growth with profitability, expense management, and

ZEQ.=10,SEQ=35,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=155545,FOLIO='30',FILE='DISK126:[08ZAH1.08ZAH15401]DM15401A.;46',USER='GLOPEZA',CD=';5-MAR-2008;19:43'

asset management and are consistent with the short-term objectives established in the annual incentive program. The Committee may use different sales growth and ROIC objectives and target share numbers from year to year to maximize alignment with then-current business objectives. Performance shares pay dividend equivalents after the end of the first year in order to simulate share ownership.

The annual option and RSU awards fully vest upon death, disability, or retirement from the Company. Performance share awards are subject to prorata vesting upon death, disability, or retirement from the Company. The definition of retirement eligibility is the same for all U.S. employees for the long-term incentive program, as well as the profit sharing program. Under this definition, an employee is retirement-eligible upon attaining any of the following:

Age 60; Age 55 and 20 years of service; or 25 years of service.

Messrs. Chen, Keyser, Loux, and Ryan are currently retirement-eligible.

The use of options and performance shares satisfies the requirements for qualified performance-based compensation under Section 162(m) of the Internal Revenue Code. The use of RSUs and performance shares also helps reduce share dilution, as compared with stock options. The Company historically makes stock option and RSU awards to current officers and employees each year on the date of the annual meeting of shareholders, and performance share awards no later than March 15 in order to qualify those awards as performance-based compensation under Section 162(m) of the Internal Revenue Code. The Company has not timed the grant of long-term incentive awards in respect of the release of material, non-public information nor for the purpose of affecting the value of executive compensation.

Based on the amounts of total compensation listed in the Summary Compensation Table, long-term variable compensation represented from 41% to 54% of total compensation for the NEOs in fiscal year 2007, which is consistent with the compensation comparator group practice as well as the Committee's overall compensation objectives.

Stock Ownership Guidelines

In 1996, the Company established stock ownership guidelines for its NEOs and other officers. The Company continues to believe that requiring executive ownership of Company stock creates alignment between executives and shareholders and encourages executives to act to increase shareholder value. The stock ownership guidelines for the NEOs are established based upon their respective positions within the Company and as follows:

User-specified TAGGED TABLE

NEO	Minimum Ownership Requirement as a Percentage of Base Salary	Currently in Compliance?
Richard L. Keyser	5x	Yes
P. Ogden Loux	3x	Yes
James T. Ryan	4x	Yes
Y. C. Chen	3x	Yes
John L. Howard	3x	Yes

end of user-specified TAGGED TABLE

These ownership guidelines must be met within three years of being elected an officer and are reviewed annually by the Board. Officers who fail to achieve these ownership levels will not be eligible to receive any stock-based awards until they achieve their required ownership levels. Shares

ZEQ.=11,SEQ=36,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=104954,FOLIO='31',FILE='DISK126:[08ZAH1.08ZAH15401]DM15401A.;46',USER='GLOPEZA',CD=';5-MAR-2008;19:43'

owned directly by the officer (including those held as a joint tenant or as tenant in common), restricted stock or RSUs, shares underlying performance shares once the number of shares is fixed, shares owned in a self-directed IRA, and certain shares owned or held for the benefit of a spouse or minor children are counted toward meeting the guidelines. Options and underlying performance awards before the number of shares is fixed are not counted toward meeting the ownership guidelines. As of the close of the 2007 fiscal year and the date of this report, all officers subject to the guidelines, including the NEOs, are in compliance with them. The Company's Business Conduct Guidelines (which are available in the Corporate Governance section of Grainger's Web site at www.grainger.com/investor) forbid employees from hedging stock ownership.

Other Benefits

NEOs and certain other officers may elect to defer receipt of up to 50% of base salary and/or 85% of annual cash incentives under the 2004 Voluntary Salary and Incentive Deferral Plan, an unfunded deferred compensation plan. The purpose of the plan is to provide executives with retirement savings and financial planning opportunities that are not available to them in tax-qualified retirement plans due to Internal Revenue Code limitations.

The NEOs and certain other Company officers also participate in the Company's Executive Death Benefit Plan. The Company has purchased and owns life insurance contracts to reduce its exposure relating to the Executive Death Benefit Plan. The plan is designed to offer a competitive death benefit for executives. The beneficiary of a participant who dies while employed by the Company is generally entitled to 120 monthly payments of 50% of the participant's monthly compensation, calculated on the basis of salary and target annual incentive under the applicable cash incentive program.

Other benefits provided to the NEOs and other officers include a car allowance and reimbursement for financial services. The car allowance and financial service reimbursements are fully taxable and not grossed up to cover taxes. Officers are allowed the business use of corporate aircraft and car service, while Messrs. Keyser and Ryan are also allowed personal use of both. These benefits represent a cost-effective method of allowing the Company's top executives to more effectively use their time. All other benefits, including the profit sharing contribution percentages and various welfare benefits, provided to NEOs and other executive officers are comparable to those provided to the majority of salaried and hourly Company employees.

end of user-specified TAGGED TABLE (1) For Messrs. Keyser, Loux, and Ryan, this represents potential amounts under the annual cash incentive award in the 2005 Incentive Plan, a 162(m)-qualified, shareholder-approved plan. The 2005 Incentive Plan establishes a pool equal to five percent (5%) of the Company's Net Earnings for this Plan Year. For 2007, the Committee used its discretion to reduce amounts to yield payments equal to those that would have been made using the same financial measures as the MIP for the other NEOs. For Messrs. Chen and Howard, this represents amounts payable under the MIP. (2) The number of shares that could have been earned for the 2007 grant of performance shares ranged from 0% to 200% of the target award and was determined based on the Company's year-over-year growth in revenue. Given the revenue growth performance, the number of shares determined for the NEOs for 2007 was 137% of target. These shares will vest at the end of fiscal year 2009 if three-year average ROIC is greater than 18%. The Company selected these measures as they balance revenue growth with profitability, expense management, and asset management and are consistent with the short-term objectives established in the annual incentive program. The Company believes that it has set the ROIC targets sufficiently high to provide the appropriate level of motivation for participants based on market and industry expectations and believes there is a strong probability that the ROIC level can be attained, thus allowing the shares to vest in 2009. (3) Represents RSU awards that vest in four years and accelerate upon retirement. Also includes a 6,000 one-time RSU award for Mr. Loux that vests in three years and a 10,000 one-time promotional RSU award for Mr. Ryan that vests in seven years; neither award automatically vests upon retirement. (4) Represents stock option awards with a ten-year term and three-year cliff vesting. (5) Awards were issued at fair market value, which the Company has consistently determined as the closing price the day before the award. (6) Represents the actual closing stock price on the option approval date. (7) Represents the full grant date fair value of awards as calculated under FAS 123R without spreading over the vesting period.

(3) Represents earnings on all nonqualified deferred compensation balances, including supplemental profit sharing plan earnings, stock price appreciation and dividend equivalent payments for vested, deferred RSUs, and for Messrs. Chen and Howard, earnings on voluntary deferrals. Investment choices for any officer, including an NEO, who elects to defer salary and/or bonus may be made only from the same investment funds available to all employees under the Company's profit sharing plan. The rate of return on the individual accounts (positive or negative) is a function of the participant-selected investment funds. A participating officer may elect to receive distribution of deferred amounts upon his or her retirement or disability or upon a specified date certain, and may elect to receive the distributions as a single sum or in annual installments over a period of up to 15 years. If a participant dies, any undistributed deferred amounts will be distributed to the participant's designated beneficiary in a single sum as soon as administratively practicable. If a participant's employment terminates for any reason other than retirement, disability or death, the deferred amounts will be paid to the participant as soon as administratively practicable. In the event of a change in control of the Company, all deferred amounts will be paid to participants in a lump sum within five days after the change in control, subject to any applicable requirements of Internal Revenue Code Section 409A.

Keyser, Loux, Ryan, and Chen have 130,595, 29,250, 51,500, and 18,350 vested, deferred RSUs outstanding, respectively. For Mr. Keyser, this includes $1,232,442 representing the present value (using a 6% discount factor) from his participation in the 1985 Executive Deferred Compensation Plan, which permitted certain employees to elect a salary reduction of between 5% and 15% (or more with special agreement) for up to four years. The Company has purchased and owns life insurance contracts to reduce its exposure relating to the 1985 Executive Deferred Compensation Plan. Under the related plan agreement, a participant was generally entitled to 180 monthly payments, commencing at age 65, in an annual amount that is based upon the amount of the salary reduction, the additional amount allocated by the Company, and the number of years from deferral to normal retirement age. Mr. Keyser previously made a voluntary election to defer salary payments under the Plan, which has not permitted deferrals for over 20 years. Mr. Keyser commenced receiving monthly payments of $10,509 under the plan in October 2007 when he reached age 65. None of the other NEOs have been eligible to participate in the Plan. The Company maintains a supplemental profit sharing plan only to the extent necessary to provide all employees with profit sharing benefits commensurate with current compensation and unaffected by limitations imposed by tax law.

Employment Contracts, Termination of Employment Arrangements, and Change in Control Arrangements

All of the NEOs and certain other key executives have entered into Change in Control Employment Agreements (CIC Agreements) with the Company. These agreements are intended to ensure that in the event of a pending or threatened change in control of the Company, the executives' full attention is focused on the best interests of the Company and its shareholders and not on their future employment prospects or by uncertainty about their compensation and benefits under those circumstances. The Company does not maintain any other employment agreements with its executives. Under each CIC Agreement, the executive is entitled to certain benefits if, within a two-year period following a change in control of the Company, (a) the executive's employment is terminated other than for cause, or (b) the executive terminates employment for good reason (for example, because Grainger reduced his authority or his aggregate benefits). Benefits include a lump-sum payment generally equal to a multiple of the sum of (i) the executive's annual salary, (ii) the executive's target annual incentive, and (iii) in connection with the Company's non-contributory profit sharing plans, a percentage of annual salary and annual incentive equal to the average percentage of covered compensation contributed by the Company under the plans for the last three fiscal years. In the case of all of the NEOs, the multiple is three. In the case of most of the other key executives, the multiple is two. The level of CIC Agreements is determined by the individual executive's position within the Company, as well as the likely value each would be required to add to any change in control transaction, and the likelihood that employment would continue after a CIC event.

Benefits that are payable under the CIC Agreements include continuation of health and dental benefits for a number of years equal to the applicable multiple. Each agreement further provides that the executive is to be made whole on an after-tax basis with respect to excise tax due as a consequence of payments (whether or not under the agreement) being classified as "excess parachute payments" under Section 280G of the Internal Revenue Code. In certain cases, the lump-sum payment upon termination is limited under the CIC Agreement to an amount such that no payments would be considered "excess parachute payments" and thus no excise tax would be due.

Deductibility of Executive Compensation; Accounting Considerations

Section 162(m) of the Internal Revenue Code generally disallows a federal income tax deduction to a public company for compensation over $1 million per fiscal year paid to the company's chief executive officer and its four other most highly compensated executive officers serving at the end of that year. Not subject to the deductibility limit, however, is compensation that qualifies as "performance-based" compensation. A Company objective is to attempt to maximize the deductibility of compensation under Section 162(m) to the extent doing so is reasonable and consistent with Company strategies and goals. Awards under the cash incentive plan in which Messrs. Keyser, Loux, and Ryan participate, gains on exercises of stock options, and shares received as the result of performance share awards are considered to be "performance-based" compensation not subject to the Section 162(m) deductibility limit. Awards of time-vested restricted stock and RSUs are not exempt from the Section 162(m) deductibility limit, and all or a portion of these awards may be nondeductible when the awards vest. While the accounting treatment applicable to the Company's compensation programs was taken into account in designing those programs, it was not a significant consideration.

Upon vesting, settlement or maturity, awards under the 2005 Incentive Plan and predecessor plans are distributed in the form of shares of the Company's common stock. Under FAS 123R, these types of awards are considered equity awards. As a result, the total amount of compensation expense

ZEQ.=1,SEQ=44,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=975115,FOLIO='39',FILE='DISK126:[08ZAH1.08ZAH15401]DQ15401A.;12',USER='EYOUNG',CD=';6-MAR-2008;14:21'

to be recorded for the awards is based on the fair value of the awards on the grant date. This fair value is then recorded ratably over the vesting period, usually three years, and is recorded to compensation expense and as an increase in paid-in capital. The amount of compensation expense is not subsequently adjusted for changes in the Company's share price, for the actual number of shares distributed, or for any other factors except for forfeitures. If an equity award is forfeited, all previously recorded compensation expensed is reversed.

Other Potential Post-Employment Payments

The Company has entered into agreements with each NEO that provide for payments at, following, or in connection with a change in control of the Company. The tables below reflect the estimated payments and benefits that would be provided in various circumstances. The amounts shown below assume that such termination or change in control was effective as of December 31, 2007, and thus only includes amounts earned through such time. However, the actual amounts that would be paid out under each circumstance can only be determined at the time of separation.

Termination

None of the NEOs are legally entitled to severance upon termination, as the Company does not maintain a severance agreement and the NEOs are not covered by employment contracts.

Retirement

The Company provides the following post-termination benefits and payments upon retirement:

Outstanding options shall become vested and executives shall have the right to exercise such options within six years from date of termination or for the remaining term of the option, whichever is less; Settlement of performance shares in common stock equal to the number of the executive's outstanding performance shares multiplied by the prorated portion of the performance period completed; Installments paid over a period of up to 15 years or a lump-sum payment of cash equal to account balances under the Profit Sharing Trust (PST), any supplemental profit sharing program, and the Voluntary Salary and Incentive Deferral Plan; Unvested RSUs shall become immediately vested; and Life insurance benefits until executive's death.

In addition to the retirement benefits listed above, NEOs will receive benefits under the Company's disability plan or payments under the Company's Executive Death Benefit Plan in the event of death or disability.

Change in Control

The Company maintains Change in Control Employment Agreements that cover each NEO. As set forth in this agreement, if an executive's employment is terminated following a change in control (other than termination by the Company for cause, involuntary termination without good reason, or by reason of death or disability) or if the executive terminates his employment in certain circumstances

ZEQ.=2,SEQ=45,EFW="2183342",CP="GRAINGER W.W. INC.",DN="1",CHK=486388,FOLIO='40',FILE='DISK126:[08ZAH1.08ZAH15401]DQ15401A.;12',USER='EYOUNG',CD=';6-MAR-2008;14:21'

defined in the agreement which constitute good reason, the Company shall provide each NEO with the following:

Lump-sum payment of cash severance benefit in an amount equal to three times the sum of an executive's base salary, target annual incentive opportunity under the MIP, and average profit sharing contribution for the previous three years; Prorated annual bonus; An amount equal to the value of the unvested portion of executive's account under the supplemental profit sharing plan; Any unexercised options, whether or not exercisable on the date of such change in control; Accelerated vesting of unvested RSUs; Settlement of performance shares in common stock equal to 100 percent of the executive's outstanding performance shares; Lump-sum payment of cash equal to account balance under the compensation deferral plan; and Gross-up tax on any payment that will become subject to any excise tax or similar tax.

The following tables illustrate the potential incremental payments and benefits based on December 31, 2007 computations that could be received by the NEOs upon a termination or change in control of the Company.

TRANSACTIONS WITH RELATED PERSONS

Grainger's Business Conduct Guidelines require that conflicts of interest in any form be avoided. The Board has adopted written policies and procedures, to be applied by the Board Affairs and Nominating Committee, for the review, approval or ratification of any transactions with related persons. Those policies and procedures apply to any proposed transaction in which Grainger is a participant, the amount involved exceeds $120,000, and any director, executive officer or significant shareholder or any immediate family member of such a person has a direct or material indirect interest. The policy requires that any such proposed transaction be reviewed by the Board Affairs and Nominating Committee to determine, among other things, the benefits of the transaction to Grainger, the availability of other sources of comparable products or services, and whether the terms of the proposed transaction are comparable to those provided to unrelated third parties.

David W. Grainger, who is the beneficial owner of approximately 9.48% of the Company's outstanding common stock, is a non-executive officer of the Company. As compensation for his services as an officer, Mr. Grainger receives an annual salary of $120,000, perquisites and benefits comparable to those received by other officers, and the ability to use Company aircraft for personal travel, subject to the requirement that he fully reimburse the Company for such use.
