3.    General Release and Waiver of Claims. In exchange and in consideration for the LTIP treatment and CMIP treatment set forth in Section 2 hereof and the other promises, obligations, and agreements undertaken by Grainger herein, all of which the Officer agrees and acknowledges are adequate and sufficient consideration, the Officer, on behalf of himself, his spouse, agents, representatives, attorneys, assigns, heirs, executors, administrators, and other personal representatives, releases and forever discharges Grainger, the Affiliates, and all of their officers, employees, directors, agents, attorneys, personal representatives, predecessors, successors, and assigns (hereinafter collectively referred to as the "Releasees") from any and all claims of any kind which he has, or might have, as of the date of this Agreement; or which are based on any facts which exist or existed on or before the date of this Agreement. The claims the Officer is releasing include, but are not limited to, all claims relating in any way to his employment at Grainger or his separation from that employment; and all claims under Title VII of the Civil Rights Act of 1964, the Civil Rights Act of 1991, 42 U.S.C. § 1981, the Equal Pay Act, the Employee Retirement Income Security Act, the Americans with Disabilities Act, the Federal Rehabilitation Act, the Age Discrimination in Employment Act ("ADEA"), the Older Worker Benefit Protection Act, the Equal Pay Act, as amended, the Illinois Fair Employment Practices Act, the Illinois Wage Payment and Collection Act, or any other federal, state or local law relating to employment, discrimination, retaliation, or wages, or under the common law of any state (including, without limitation, claims relating to contracts, wrongful discharge, retaliatory discharge, defamation, intentional or negligent infliction of emotional distress, and wrongful termination of benefits). The Officer also releases and forever discharges Grainger and all other Releasees from any and all other demands, claims, causes of action, obligations, agreements, promises, representations, damages, suits, and liabilities whatsoever, both known and unknown, in law or in equity, which he has or might have as of the date of this Agreement. The Officer understands that this Section 3 of this Agreement contains a complete and general release of any claim that he now has against Grainger and all other Releasees or could ever have against Grainger and all other Releasees, based on any fact, event, or omission that has occurred up to the time at which he signs the Agreement.

The Officer does not intend nor is he waiving any rights or claims that may arise after the date that he signs this Agreement, or any right on the Officer's part to challenge the knowing and voluntary nature of this release with respect to claims under ADEA.

Also excluded from this Agreement are Officer's rights to file a charge with the Equal Employment Opportunity Commission or any other federal, state, or local agency, and to participate in an agency investigation. Officer, however, waives all rights to recover money or other individual relief if any administrative agency or another person or entity pursues any claim on Officer's behalf arising out of or related to Officer's employment with Grainger. Officer represents that there is no lawsuit or other claim against Grainger pending in any federal, state, or municipal court or other tribunal which has not been addressed herein.

The Officer understands and agrees that this waiver and release is an essential and material term of this Agreement and that, without such provision, no agreement would have been reached by the parties.

In the event that a Court or Administrative Tribunal of competent jurisdiction concludes that any term, provision or section of this Agreement is invalid or unenforceable (and, in the case of the Competition Agreement incorporated into Section 4 of this Agreement, such provision is not modified by a Court or Administrative Tribunal to be enforceable), then said term, provision, or section shall be deemed eliminated from this Agreement to the extent necessary and in order to permit the remaining portions of the Agreement to be enforced. Any such eliminations shall not affect Grainger's entitlement, if any, to receive, pursuant to Sections 4 and 9 hereof, amounts paid and benefits provided to the Officer under this Agreement.

15.    Confidentiality of Agreement. The Officer represents and agrees (and acknowledges the sufficiency of the consideration for his agreement), except as otherwise required by law, to keep the terms, amounts and facts surrounding this Agreement completely confidential, save claims involving workplace harassment, and that the Officer will not disclose any information concerning this Agreement to anyone; provided, however, that this section will not prevent the Officer from disclosing information concerning this Agreement to the Officer's current spouse, attorneys, accountants, financial or tax advisors, a designated Grainger official, or as required by law. Notwithstanding, in accordance with U.S. Treasury Regulation 1.6011-4(b)(3)(iii), each party (and each employee, representative, or other agent of each party) to this Agreement may disclose to all persons, without limitation of any kind, the tax treatment, tax structure, and all materials of any kind provided to the other party relating to such tax treatment and tax structure. Nothing in this confidentiality provision prohibits Officer from reporting possible violations of federal law or regulation to any governmental agency or entity, including but not limited to the Department of Justice, the Securities and Exchange Commission, the Congress, and any agency Inspector General, or making other disclosures that are protected under the whistleblower provisions of federal law or regulation. Officer does not need the prior authorization of the Company to make any such reports or disclosures and Officer is not required to notify the Company that Officer has made such reports or disclosures and nothing in this confidentiality provision prohibits Officer from receiving a monetary award for providing information directly to a government agency. Officer may disclose Trade Secrets in

confidence, either directly or indirectly, to a Federal, State, or local government official, or to an attorney, solely for the purpose of reporting or investigating a suspected violation of law, or in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Additionally, Officer may file a lawsuit, to include retaliation, in conjunction with reporting a suspected violation of law and may disclose related Trade Secrets to his attorney and use them in related court proceedings, as long as the individual files documents containing the Trade Secret under seal and does not otherwise disclose the Trade Secret except pursuant to Court Order.

16.    Jurisdiction and Governing Law. The Officer acknowledges that for the purpose of this Agreement as well as his employment with Grainger, he is an Illinois employee. This Agreement shall in all respects be interpreted, enforced, and governed by and under the laws of the State of Illinois, without regard to its conflicts of law principles.

17.    Voluntary Agreement. The Officer acknowledges that the payments and benefits that Grainger is providing hereunder exceed the compensation and benefits otherwise payable to the Officer or on the Officer's behalf and that such payments and benefits are provided by Grainger in exchange for execution of this Agreement. The Officer acknowledges that he was given twenty-one (21) days to consider the terms of this Agreement, that the Officer may revoke this Agreement at any time within seven (7) days after the date that the Officer signs it, and that he has been advised to and has had the opportunity to seek out counsel of his own choice. Any revocation must be communicated in writing, via personal delivery or overnight mail, to Nancy Berardinelli-Krantz, Senior Vice President and Chief Legal Officer, W.W. Grainger, Inc., 100 Grainger Parkway, Lake Forest, Illinois 60045. The Officer further understands that this Agreement does not take effect until after the expiration of the seven (7) day period for revocation. Unless the timeline for Officer’s consideration of the terms of this Agreement is extended by Grainger, all referenced payments and applicable benefits identified in this Agreement will automatically cease on the 21st day should the Officer not return a fully executed copy of this Agreement to Grainger within the specified 21-day consideration period. The Officer has read this Agreement and understands its terms.

18.    Tax Matters

a.Grainger may withhold from any and all amounts payable under this Agreement or otherwise such federal, state and local taxes as may be required to be withheld pursuant to any applicable law or regulation.

b.The intent of the parties is that payments and benefits under this Agreement comply with Internal Revenue Code Section 409A and the regulations and guidance promulgated thereunder (collectively "Code Section 409A") and, accordingly, to the maximum extent permitted, this Agreement shall be interpreted to be in compliance therewith. To the extent that any provision hereof is modified in order to comply with Code

Section 409A, such modification shall be made in good faith and shall, to the maximum extent reasonably possible, maintain the original intent and economic benefit to the Officer and Grainger of the applicable provision without violating the provisions of Code Section 409A. Notwithstanding any other provision of this Agreement, Grainger shall not be obligated to guarantee any particular tax result for the Officer with respect to any payment provided to the Officer hereunder, and the Officer shall be responsible for any taxes imposed on the Officer with respect to any such payment.

c.Notwithstanding anything to the contrary in this Agreement, with respect to any amounts referenced herein that constitute an earned and vested payment pursuant to a separate “nonqualified deferred compensation” agreement that is subject to the requirements of Code Section 409A (a “409A Arrangement”), such amounts shall be paid at the original times provided in the 409A Arrangement to the extent required by Code Section 409A.

d.Notwithstanding anything to the contrary in this Agreement, if the Officer is deemed on the date of termination to be a "specified employee" within the meaning of that term under Code Section 409A(a)(2)(B), then with regard to any payment or the provision of any benefit that is considered “nonqualified deferred compensation” under Code Section 409A payable on account of a "separation from service," such payment or benefit shall not be made or provided until the date which is the earlier of (A) the expiration of the six (6)-month period measured from the date of such "separation from service" of the Officer, and (B) the date of the Officer’s death, in each case to the extent required under Code Section 409A. Upon the expiration of the foregoing delay period, all payments and benefits delayed pursuant to this section (whether they would have otherwise been payable in a single sum or in installments in the absence of such delay) shall be paid or reimbursed to the Officer in a lump sum, and any remaining payments and benefits due under this Agreement shall be paid or provided in accordance with the normal payment dates specified for them herein.

e.To the extent that reimbursements or other in-kind benefits under this Agreement constitute "nonqualified deferred compensation" for purposes of Code Section 409A, (A) all such expenses or other reimbursements hereunder shall be made on or prior to the last day of the taxable year following the taxable year in which such expenses were incurred by the Officer, (B) any right to such reimbursement or in-kind benefits shall not be subject to liquidation or exchange for another benefit, and (C) no such reimbursement, expenses eligible for reimbursement, or in-kind benefits provided in any taxable year shall in any way affect the expenses eligible

for reimbursement, or in-kind benefits to be provided, in any other taxable year.

f.For purposes of Code Section 409A, the Officer’s right to receive installment payments, if any, pursuant to this Agreement shall be treated as a right to receive a series of separate and distinct payments. Whenever a payment, if any, under this Agreement specifies a payment period with reference to a number of days, the actual date of payment within the specified period shall be within the sole discretion of the Company.

g.Notwithstanding any other provision of this Agreement to the contrary, in no event shall any payment under this Agreement that constitutes "nonqualified deferred compensation" for purposes of Code Section 409A be subject to offset by any other amount unless otherwise permitted by Code Section 409A.

I have read this Separation Agreement and General Release and understand all terms contained herein. I voluntarily execute this Separation Agreement and General Release with full knowledge of

its meaning on this date ___________________.
