In exchange and in consideration for the promises, obligations, and agreements undertaken by Grainger herein, 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 5 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 to 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. Notwithstanding the foregoing, the Officer does not waive any rights he may have to benefits available after termination under any company-sponsored employee benefit plan, or any rights he may have to insurance protection and/or indemnification for actions taken by the Officer while an employee and or Officer of Grainger. The Officer acknowledges that this is an individually negotiated agreement and he agrees that his termination of employment with Grainger is not pursuant to an employment termination program as that term is used in the ADEA.

Excluded from this General Release and Waiver are any claims or rights which Officer cannot waive by law, including workers’ compensation claims, as well as

any claims for breach of this Agreement. 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.

6. Covenants Not to Sue. a) The Officer agrees not to pursue or permit to be filed or pursued against Grainger or any Releasee, any claim or action before any federal, state, or local, administrative, legislative or judicial body based on any claim or liability described in the foregoing section, or otherwise related in any way to the Officer’s employment with Grainger, and understands that the purpose of this waiver and release is to dispose of, with finality, any claims that the Officer may have against Grainger and all other Releasees so that there will be no disputes or controversies concerning any matters following the Separation Date. The Officer has no such claim or lawsuit outstanding at this time, and the Officer does not know of any such potential claim or lawsuit that may be asserted by the Officer or any other person in connection with the Officer’s employment with Grainger. The Officer understands that the terms of this section do not apply to a challenge to the knowing and voluntary nature of this release with respect to claims under ADEA. b) In turn, except as otherwise provided in Section 13 below, Grainger agrees not to pursue any claim or sue Officer for any action or conduct that may otherwise be attributable to Officer during the term of his active employment and through the date that he executes this Agreement.

7. Unfair Competition.

a. The Officer acknowledges that in connection with the performance of his duties for Grainger, he has either created, used or accessed confidential and trade secret information of Grainger and the Affiliates (as further described in Section 11 below). The Officer further acknowledges that his employment with or other work on behalf of a Competitor (defined in Section 7(b) and 7(c)below) would necessarily and inevitably lead to his unauthorized use or disclosure of such confidential and trade secret information. Accordingly, the Officer agrees that based upon the special consideration provided by way of this Agreement, and for a period beginning on the date hereof and continuing until the first anniversary of the Termination Date, and within one hundred (100) miles of any branch, office or distribution center of Grainger or an Affiliate to which he was assigned either physically or electronically within two years prior to ceasing active employment with the Company, as well as on behalf of any Competitor specifically identified on Exhibit A,

anywhere in the United States (the “Restricted Area”), he will not directly or indirectly, whether as executive, officer, director, owner, shareholder, partner, associate, consultant, advisor, contractor, joint venturer, manager, agent, representative or otherwise, work for a Competitor at said location or within the above designated 100 mile radius in any capacity that would involve:

i. the same or substantially similar functions or responsibilities to those the Officer performed for Grainger within two years of the Separation Date; or

ii. supervision over the same or substantially similar responsibilities to those the Officer performed for Grainger within two years of the Separation Date; or

iii. assisting a Competitor in decisions that involve or affect the same or a substantially similar area of operations to those the Officer was involved in with Grainger within two years of the Separation Date.

The Officer may not circumvent the purpose of this restriction by engaging in business within the Restricted Area through remote means such as telephone, correspondence, electronic or any other form of computerized communication.

b. A “Competitor” is any person or legal entity or branch, office or operation thereof (a “Firm”) that engages in business that is competitive with the business activities of Grainger through, but not limited to: (i) selling maintenance, repair and operating (MRO) supplies to North American businesses; (ii) providing indirect materials management services to North American businesses; (iii) aggregating information regarding indirect materials for the purpose of conducting business-to-business Internet commerce with North American businesses; or (iv) indirect materials procurement services to North American businesses. Without limiting the generality of the foregoing, each of the Firms identified on Exhibit A hereto constitutes a Competitor.

c. A Firm shall not be deemed a Competitor unless the aggregate revenue of such Firm for its most recently completed fiscal year that is attributable to the categories of products and services set forth in clauses (i) through (iv) of Section 7(b) above equals more than 5% of the aggregate amount of consolidated revenue that Grainger derived from such categories of products and services during its most recently completed fiscal year.

d. The Officer may at any time, or from time to time, request Grainger to advise the Officer in writing whether or not Grainger considers a specified Firm to be a Competitor. Any such request shall be made by written notice to Grainger that includes: (i) the name of the specific business unit for which the Officer proposes to work; (ii) the name or names of any parent companies of such business unit; (iii) a description of the specific services which the Officer proposes to perform for such business unit; (iv) a statement as to why the Officer believes that the performance of such

services will not adversely affect Grainger’s legitimate protectible interests; and (v) the requested date of Grainger’s response (which date shall be at least 14 days after the date of Grainger’s receipt of the Officer’s request).

e. The Officer specifically recognizes and affirms that Section 7(a) is a material and important term of this Agreement. If any court of competent jurisdiction determines that the covenant set forth in Section 7(a), or any part thereof, would be unenforceable due to the stated duration or geographical scope of such covenant, such court shall have the power to reduce the duration or scope of such provision, as the case may be, and, as so reduced, such provision shall then be enforceable. If the court does not modify such provision as aforeseaid, or if the provision is otherwise held or found invalid or unenforceable for any reason whatsoever, then (without limiting any other remedies which may be available to Grainger under this Agreement or otherwise, including, without limitation, Section 13 hereof), Grainger shall be entitled to cease making payments and furnishing benefits to the Officer pursuant to this Agreement and shall be further entitled to receive from the Officer reimbursement of all Compensation Continuation Payments and other payments and benefits theretofore furnished to the Employee pursuant to this Agreement.

Pending such reimbursement, and without limiting Grainger’s rights under Section 13 hereof or any other rights and remedies of Grainger, Grainger shall have the right to offset the amount of such reimbursement against any amount or benefit otherwise payable to the Officer.

8. Non-Disparagement. The Officer agrees to take no action in derogation or disparagement of Grainger or the Affiliates, or their respective businesses or strategic interests, or the Releasees. The Officer further agrees not to discuss or otherwise comment on Grainger or any Affiliate, or their respective businesses or strategic interests, or the Releasees, in public, for publication on electronic media (including but not limited to chat rooms, message boards, or the like), in similar public forums, or otherwise, other than communication of publicly available information. In turn, Grainger agrees that its Senior Corporate Officers will make no public statements nor sanction any action in derogation or disparagement of the Officer.

9. Non-Interference with Business Relationships. The Officer agrees not to interfere with the employment of any Grainger employee or otherwise with the business relationships of Grainger, and to the extent required to enforce this promise, agrees not to induce, directly or indirectly, any Grainger customer or supplier to breach any contract with Grainger, and further agrees not to solicit, attempt to hire, or hire, directly or indirectly, any Grainger employee, or request, induce or advise any such employee to leave the employment of Grainger at any time before the Termination Date and for one year thereafter. Should the Officer wish to hire a Grainger employee in contravention of this Section 9, or to perform work which is precluded by the Officer’s non-competition obligations set forth in Section 7 hereof, the Officer understands that he may request that Grainger agree that the Officer may perform such

work or offer employment to such employee, and that with Grainger’s prior written agreement, which it may withhold at its sole discretion, the Officer may do so.

10. Return of Property: Business Expenses. The Officer shall promptly account for and return to Grainger all Grainger property, including but not limited to proprietary information, which is in the Officer’s possession or control. This property includes (but is not limited to) Officer’s Grainger work computer along with related drives and peripherals, correspondence, financial materials, files, reports, minutes, plans, records, surveys, diagrams, computer print-outs, floppy disks, manuals, client/customer information and documentation, and any company research, goals, objectives, recommendations, proposals or other information relating to Grainger, its business, or its clients or customers, which is not generally known to the public, and which the Officer acquired in the course of his employment with Grainger. Notwithstanding, Officer shall be permitted to retain his Grainger cell phone along with his current telephone number. The Officer further agrees that all business expenses incurred prior to the Separation Date that are reimbursable in accordance with Grainger’s normal policies and procedures have been reimbursed to the Officer or submitted for reimbursement, and that other than as specifically provided in this Agreement, the Officer will not incur any additional business expenses after the Separation Date unless previously authorized and approved in writing by Grainger.

11. Confidential Information. The Officer agrees to refrain from ever disclosing to anyone outside the employment of Grainger any confidential or trade secret information, whether in oral, written and/or electronic form, including but not limited to information that (a) relates to Grainger’s or the Affiliates’ past, present and future research, development, technical and non-technical data and designs, finances, marketing, products, services, customers, suppliers, and other business activities of any kind or (b) has been identified, either orally or in writing, as confidential by Grainger or any Affiliate; provided that this limitation shall not apply to information that is part of the public domain through no breach of this Agreement or is acquired from a third party not under similar nondisclosure obligations to Grainger or such Affiliate. The Officer acknowledges that his obligations under any confidentiality or nondisclosure or similar agreements or provisions that the Officer previously executed will remain in full force and effect. Further, through the Termination Date, the Officer agrees to fully comply with all policies of Grainger regarding confidential or trade secret information.

12. Cooperation with Company. The Officer agrees, during the term of this Agreement as well as during the 6 month period immediately thereafter, to both make himself available and to provide reasonable cooperation to Grainger or its attorneys to assist Grainger or serve as a witness in connection with any matter, litigation, potential litigation, or other business matter in which the Officer may have knowledge, information, or expertise. The Officer also agrees to provide Grainger or its designated representatives, upon request, with information and assistance about programs, processes,

and projects related to the Officer’s job responsibilities while employed by Grainger; to answer any questions relating to the work to which the Officer was assigned; and to otherwise provide reasonable cooperation to Grainger regarding matters relating to this Agreement and the Officer’s employment with Grainger. Grainger will reimburse the Officer for any reasonable expenses he incurs in activities which he undertakes at Grainger’s request pursuant to this Section 12.

13. Breach of Agreement - Misconduct. The Officer understands and agrees that if, after receiving all or any part of the payments and benefits described herein, the Officer breaches this Agreement, or commits or is discovered to have committed any act of misconduct including any violation of Company Policy, embezzlement, fraud or theft with respect to the property of Grainger, or causes or is discovered to have caused, any loss, damage, injury or other endangerment to Grainger’s property, reputation or past, present, or future directors, officers or employees, Grainger reserves the right to demand repayment of all such payments and benefits. Grainger shall further be released from any future payment then or thereafter otherwise due and shall discontinue any and all benefit coverage (other than vested benefits under the PST and SPSP, and COBRA coverage. To the extent permitted by law, the Officer further understands and agrees that Grainger reserves the right to pursue all other available remedies in an effort to preserve its legitimate business interests. The Officer also agrees to indemnify and hold harmless Grainger from any loss, cost, damage, or expense, including fees, which Grainger may incur because of the Officer’s violation of this Agreement. The Officer understands that this Section 13 does not apply to a challenge to the knowing and voluntary nature of this release with respect to claims under ADEA. Should a dispute arise relative to any claim associated with this Section that is not otherwise privately resolved between Grainger and the Officer, it is understood and agreed that such dispute shall then be submitted for arbitration with an arbitrator mutually selected through the American Arbitration Association’s panel selection process.

14. Supersedes Other Agreements. Other than any vested rights that the Officer may have under employee benefit plans subject to ERISA, the Officer understands that this Agreement supersedes any and all obligations (written or oral) which Grainger otherwise might have to the Officer for compensation or other expectations of remuneration or benefit on the Officer’s part. The Officer specifically acknowledges that all of Grainger’s obligations under the Change in Control Employment Agreement entered into between Grainger and the Officer (the “Change in Control Agreement”) shall become null and void as of the Separation Date. Notwithstanding the above and based upon the special consideration provided by way of this Agreement, all obligatory provisions relating to the Officer that are contained within any Grainger Non-Competition Agreement, Stock Option, Special RSU, or Performance Share Agreement entered into between the Officer and Grainger, or other Grainger Governance shall remain in full force and effect as originally executed and be incorporated by reference as being materials parts of this Agreement.

18. Entire Understanding. The Officer understands and agrees that this Agreement, including Exhibit A hereto, contains the entire understanding between the parties and may not be amended except by mutual agreement in an amendment executed by both parties.

19. Severability. The provisions of this Agreement are declared to be severable, which means that if any provision of this Agreement or the application thereof is found to be invalid, the invalidity shall not affect other provisions or applications of this Agreement, which will be given effect without the invalid provisions or applications.

The Officer represents and agrees, 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 spouse, attorneys, accountants, financial or tax advisors, a designated Grainger official, or as required by law or spouse.

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. 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.
