Exhibit

In consideration of the Executive's agreement to enter into an Unfair Competition Agreement with the Company concurrently with this Agreement on the Grant Date (the "Unfair Competition Agreement"), the Company desires to grant the Executive an award of performance restricted stock units (the "PRSUs"), providing for the issuance of shares of the Company's common stock ("Shares") pursuant to the W.W. Grainger, Inc. 2015 Incentive Plan (as may be amended from time to time, the "Plan") subject to the Company's attainment of certain long-term performance goals and the Executive agrees to enter into the Unfair Competition Agreement and accept such PRSUs on the terms and conditions set forth in this Agreement, the Plan and the Unfair Competition Agreement. Capitalized terms used but not defined in this Agreement have the meanings specified in the Plan.

1.01 Grant. Subject to the terms and conditions of this Agreement, the Plan and the Unfair Competition Agreement (the terms of which are hereby incorporated herein by reference) and effective on the Grant Date, the Company hereby grants to the Executive the number of PRSUs (the "Target PRSUs") as specified in the April 2, 2018 award grant notice posted to the Executive's electronic investment account maintained with the brokerage firm/third party service provider engaged by the Company in connection with the administration of the Plan (the "Administrator"). Each PRSU represents a contractual right to receive one (1) Share upon the satisfaction of the terms and conditions of this Agreement. The actual number of PRSUs that may become vested and settled pursuant to this Agreement will depend on the Company’s average return on invested capital ("ROIC") during the period of January 1, 2018 through December 31, 2020 (the "Measurement Period"). For this purpose, ROIC means the Company’s operating earnings divided by its net working assets, as determined by the Committee in its sole discretion. The actual number of vested PRSUs will be determined in accordance with Section 2 below.

For purposes of the foregoing, the level of achievement of the ROIC Target shall be determined by the Committee in its sole discretion by calculating the Company's return on invested capital for each applicable fiscal year by dividing (i) the Company's operating earnings for the applicable fiscal year, by (ii) the Company's net working assets for the applicable fiscal year. Further, the actual number of PRSUs subject to this Agreement based upon the Company's achievement of the ROIC Target shall be determined by applying straight-line interpolation rounded down to the nearest whole number of PRSUs. If the PRSUs vest, then in settlement of the PRSUs, the Executive will receive a number of shares of Common Stock equal to the number of PRSUs determined under this Section 2.01, subject, however, to the withholding provisions below. If the PRSUs do not vest, then they will be forfeited in full and the Executive shall have no further rights with respect to the award hereunder.

2.02 Vesting of PSUs. If the Executive remains continuously employed by the Employer (or any other Subsidiary or Affiliate) through the third anniversary of the Grant Date (the "PRSUS Vesting Date"), the actual number of PRSUs as determined pursuant to Section 2.01 shall become fully vested on such date and the Executive shall be entitled to receive the underlying Shares as provided herein. The PRSUs shall not vest before the PRSU Vesting Date unless otherwise provided or permitted by the Plan or this Agreement, and any PRSUs that do not vest shall be forfeited in full and the Executive shall have no further rights with respect to such PRSUs. Each PRSU that becomes vested as provided herein shall be settled in accordance with Section 2.06. No dividend equivalents will be paid on the shares of Common Stock underlying the PRSUs.

2.03 Effect of Termination of Employment. Except as otherwise stated in the Plan, if the Executive's employment or service is terminated prior to the PRSU Vesting Date for any reason whatsoever other than the Executive's death, Disability (defined below) or retirement, the PRSU shall be forfeited in their entirety. If the Executive is a resident of, or employed in, the United States, "Termination Date" shall mean the effective date of termination of the Executive's employment. If the Executive is a resident of, or employed outside of, the United States, "Termination Date" shall mean the earliest of (i) the date on which notice of termination is provided to the Executive, (ii) the last day of the Executive's active service with the Employer or (iii) the last day on which the Executive is an employee of the Employer, as determined in each case without including any required advanced notice period and irrespective of the status of the termination under local labor or employment laws.

2.05 Effect of Retirement of the Executive. If the Executive’s employment or service is terminated prior to the PRSU Vesting Date due to the retirement of the Executive, the Executive will continue vesting in accordance with Section 2.02 as if the Executive had not been terminated. Each Actual PRSU that becomes vested as provided herein shall be settled in accordance with Section 2.06. For purposes of this Agreement, "retirement" shall mean the Executive’s termination of service with (i) 25 years of service, (ii) 20 years of service and attainment of age 55, or (iii) attainment of age 60.

2.06 Settlement. Upon the PRSU Vesting Date, the Company shall, as soon as practicable (but in no event later than 60 days following the applicable PRSU Vesting Date), settle the PRSU by registering Shares in the Executive's name and delivering such Shares to the Executive's electronic stock plan account maintained by the Administrator. At the discretion of the Committee, and subject to such policies and procedures as it may adopt from time to time, the Executive's PRSU may be settled in the form of: (i) cash, to the extent settlement in Shares (a) is prohibited under applicable Laws, (b) would require the Executive, the Company or the Employer to obtain the approval of any governmental and/or regulatory body in the Executive's country of residence (and country of employment, if different), or (c) is administratively burdensome or (ii) Shares, but the Company may require the Executive to immediately sell such Shares if necessary to comply with applicable Laws (in which case, the Executive hereby expressly authorizes the Company to issue sales instructions in relation to such Shares on the Executive's behalf).

3.01 Recoupment in Event of Misconduct. If the Company determines that the Executive has committed fraud against the Company or has engaged in any criminal conduct that involves or is related to the Company, or any other conduct that violates Company policy, and such Executive has received or is entitled to receive performance stock units, performance restricted stock units, stock options, restricted stock units or cash incentive compensation (collectively, "Incentive Compensation"), then the Company shall have the right to cancel the Incentive Compensation, require the return of shares of Common Stock acquired under the Plan, recapture any gain realized upon the sale of shares of Common Stock acquired under the Plan or take any other action it deems appropriate under the circumstances with respect to recouping the Incentive Compensation. The Company shall have sole discretion in determining whether the Executive's conduct was in compliance with applicable Law or Company policy and the extent to which the Company will seek recovery of the Incentive Compensation notwithstanding any other remedies available to the Company. If the Executive engages in misconduct or is believed to have engaged in misconduct, including but not limited to any violation of any of Executive's obligations under the Unfair Competition Agreement, the Company shall be entitled to take the actions outlined above for recouping the Incentive Compensation, as the Company deems appropriate under the circumstances.

paid or settled to the Executive during the period covered by the Subject Financials as set forth herein. If the payment or settlement of Incentive Compensation would have been lower had the achievement of applicable financial performance goals been calculated based on restated financial results with respect to the Subject Financials, the Company may, if it determines it appropriate in its sole discretion, recover the portion of the paid or settled Incentive Compensation in excess of the payment or settlement that would have been made based on restated financial results. The Company will not seek to recover Incentive Compensation received or settled more than three (3) years after the date of the initial filing that contained the Subject Financials.

3.03 Implementation. For purposes of this Article III, the Executive expressly authorizes the Company to issue instructions, on behalf of the Executive, to the Administrator (and/or any other brokerage firm/third party service provider engaged by the Company to hold Shares and other amounts acquired under the Plan) to reconvey, transfer or otherwise return to the Company any Incentive Compensation subject to recoupment hereunder. Executive acknowledges and agrees that the Company's rights hereunder shall not be affected in any way by any subsequent change in the Executive’s status, including retirement or termination of employment (including due to death or Disability).

4.01 Tax-Related Items. Regardless of any action the Company or the Employer takes with respect to any or all income tax (including U.S. federal, state and local taxes or non-U.S. taxes), social insurance, payroll tax, payment on account or other tax-related withholding ("Tax-Related Items"), the Executive acknowledges and agrees that the ultimate liability for all Tax-Related Items legally due by the Executive is and remains the Executive's responsibility and that the Company and the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the PRSU, including the grant of the PRSU, the vesting of the PRSU, the subsequent sale of any Shares acquired pursuant to the PRSU and the receipt of any dividends and (ii) do not commit to structure the terms of the grant or any aspect of the PRSU to reduce or eliminate the Executive's liability for Tax-Related Items.

4.02 Tax Withholding Obligations. Prior to the delivery of Shares (or cash) upon the vesting of the PRSU, if the Executive's country of residence (and country of employment, if different) requires withholding of Tax-Related Items, the Company shall withhold a sufficient number of whole Shares otherwise issuable upon the vesting of the PRSU that have an aggregate Fair Market Value sufficient to pay the Tax-Related Items required to be withheld with respect to the Shares or the cash equivalent. Depending on the withholding method specified in the Plan, the Company may withhold or account for Tax-Related Items by considering applicable statutory withholding rates or other applicable withholding rates, including maximum applicable rates, in which case the Company shall make a cash payment to the Executive equal to the over-withheld amount, if applicable, as soon as administratively practicable. The cash equivalent of the Shares withheld will be used to settle the obligation to withhold the Tax-Related Items. In the event that the withholding of Shares is prohibited under applicable Law or otherwise may trigger adverse consequences to the Company or the Employer, the Company and the Employer may withhold the Tax-Related Items required to be withheld with respect to the Shares in cash from the Executive's regular salary and/or wages

or any other amounts payable to the Executive, or may require the Executive to personally make payment of the Tax-Related Items required to be withheld. In the event the withholding requirements are not satisfied through the withholding of Shares by the Company or through the withholding of cash from the Executive's regular salary and/or wages or other amounts payable to the Executive, no Shares will be issued to the Executive (or the Executive's estate) upon vesting of the PRSU unless and until satisfactory arrangements (as determined by the Committee) have been made by the Executive with respect to the payment of any Tax-Related Items that the Company or the Employer determines, in its sole discretion, must be withheld or collected with respect to such PRSUs. If the obligation for the Executive's Tax-Related Items is satisfied by withholding a number of Shares as described herein, the Executive shall be deemed to have been issued the full number of Shares issuable upon vesting, notwithstanding that a number of the Shares is held back solely for the purpose of paying the Tax-Related Items due as a result of the vesting or any other aspect of the PRSU.

The Executive will pay to the Company or the Employer any amount of Tax-Related Items that the Company or the Employer may be required to withhold as a result of the Executive's participation in the Plan or the Executive's acquisition of Shares that cannot be satisfied by the means described in this Article IV. The Company may refuse to deliver any Shares due upon vesting of the PRSU if the Executive fails to comply with his or her obligations in connection with the Tax-Related Items as described herein. If the Executive is subject to taxation in more than one jurisdiction, the Executive acknowledges that the Company, the Employer or one or more of their respective Subsidiaries may be required to withhold or account for Tax-Related Items in more than one jurisdiction. The Executive hereby consents to any action reasonably taken by the Company and the Employer to meet his or her obligation for Tax-Related Items. By accepting this grant of the PRSU, the Executive expressly consents to the withholding of Shares and/or withholding from the Executive's regular salary and/or wages or other amounts payable to the Executive as provided for hereunder. All other Tax-Related Items related to the PRSU and any Shares delivered in payment thereof are the Executive's sole responsibility.

5.02 Foreign Asset and Account Reporting Requirements. The Executive acknowledges that there may be certain foreign asset and/or account reporting requirements, which may affect the Executive's ability to acquire or hold Shares acquired under the Plan or cash received from participating in the Plan (including from any dividends or dividend equivalent payments) in a brokerage or bank account outside the Executive's country of residence (and country of employment, if different). The Executive may be required to report such accounts, assets or transactions to the tax or other authorities in the Executive's country of residence (and country of employment, if different). The Executive acknowledges and agrees that it is his or her personal responsibility to be compliant with such Laws.

5.03 Country Specific Addendum. Notwithstanding any provisions of this Agreement to the contrary, the PRSU shall be subject to any special terms and conditions for the Executive's country of residence (and country of employment, if different) set forth in the addendum to this Agreement ("Addendum"). If the Executive transfers residence and/or employment to another country reflected in an Addendum at the time of transfer, the special terms and conditions for such country will apply to the Executive to the extent the Company determines, in its sole discretion, that the application of such special terms and conditions is necessary or advisable in order to comply with local Laws or to facilitate the operation and administration of the PRSU and the Plan (or the Company may establish alternative terms and conditions as may be necessary or advisable to accommodate the Executive's transfer). In all circumstances, any applicable Addendum shall constitute part of this Agreement.

5.04 Controlling Language. The Executive acknowledges and agrees that it is the Executive's express intent that this Agreement, the Plan, the Unfair Competition Agreement and all other documents, notices and legal proceedings entered into, given or instituted pursuant to the PRSU be drawn up in English. If the Executive has received this Agreement, the Plan, the Unfair Competition Agreement or any other documents related to the PRSU translated into a language other than English and the meaning of any translated version is different than the English version, the English version will control.

6.03 Administration. The Committee shall have the power to interpret the Plan and this Agreement and to adopt such rules for the administration, interpretation, and application of the Plan as are consistent therewith and to interpret or revoke any such rules. All actions taken and all interpretations and determinations made by the Committee shall be final and binding upon the Executive, the Company, and all other Persons. No member of the Committee shall be personally liable for any action, determination, or interpretation made in good faith with respect to the Plan or this Agreement.

6.04 No Employment Rights.

Without limiting the generality of the foregoing, the Committee shall have the discretion to adjust the terms and conditions of any award of PRSUs to correct for any windfalls or shortfalls in such PRSU which, in the Committee's determination, arise from factors beyond the Executive's control; provided, however, that the Committee's authority with respect to any PRSU to a "covered employee," as defined in Section 162(m)(3) of the Code, shall be limited to decreasing, and not increasing, such PRSU.

6.06 Compliance with Law. The Company shall not be required to issue or deliver any Shares pursuant to this Agreement pending compliance with all applicable Laws (including any registration requirements or tax withholding requirements) and compliance with the Laws and practices of any stock exchange or quotation system upon which the Shares are listed or quoted. If the Executive resides or is employed outside of the United States, the Executive agrees, as a condition of the grant of the PRSUs, to repatriate all payments attributable to the Shares and/or cash acquired under the Plan (including, but not limited to, dividends and any proceeds derived from the sale of Shares acquired pursuant to the PRSUs) if required by and in accordance with local Laws in the Executive’s country of residence (and country of employment, if different). In addition, the Executive also agrees to take any and all actions, and consent to any and all actions taken by the Company, its Subsidiaries and the Employer, as may be required to allow the Company, its Subsidiaries and the Employer to comply with local Laws in the Executive’s country of residence (and country of employment, if different). Finally, the Executive agrees to take any and all actions as may be required to comply with the Executive’s personal legal and tax obligations under local Laws in the Executive’s country of residence (and country of employment, if different).
