Carruthers will resign from the office of Senior Vice President effective July 31, 2015 (the “Resignation Date”) and agrees to execute such documents as may be required to effect his resignation as an officer or director of the Company, its parent or any of its affiliates. Until December 31, 2015 (the “Separation Date”) Carruthers will receive his regular salary and benefit coverage, and in so doing will assist the Company with the transition of his responsibilities, as required. His employment status with the Company will terminate for all purposes on the earlier of December 31, 2017 or the date on which Separation Payments cease (the “Termination Date”).

Separation Payments. Subject to continued compliance by Carruthers with his obligations under section 16 hereunder, commencing on the first pay date following the Separation Date, the Company shall pay the equivalent of eighteen (18) months of salary to Carruthers, calculated at his current base rate of pay (the “Separation Payments”), less required deductions with no other allowances except as called out below. Payments shall be made on the Company’s regular pay dates and pursuant to the Company’s normal payroll processes on a pro-rated basis over a period of eighteen (18) months, or pro-rated over 24 months ending December 31, 2017, at Carruthers’ election. In the event of the death of Carruthers prior to the Termination Date, the balance of any Separation Payments to which he is entitled at that time shall be paid to the duly appointed personal representative of his estate. The Separation Payments are inclusive of any statutory entitlements.

Management Incentive Program (“MIP”). Carruthers’ current and future participation in the MIP shall be governed by way of this Section as well as the provisions of the Plan then in effect. In or about March 2016, Carruthers will receive a payment under the MIP in respect of the full year 2015, based upon his current base salary subject to the applicable percentage multiple and the actual performance of the Company, and pursuant to the terms of the Plan then in effect as would be applicable to Senior Officers of the Company. No other MIP payments will be made to Carruthers beyond those outlined above.

Vacation Pay/PTO. Carruthers will be paid all vacation pay/PTO outstanding and accrued as of the Separation Date on the date of the first Separation Payment in accordance with the Company’s practice and subject to applicable United States and Canadian provisions. No additional vacation or PTO will be earned after this date.

Group Health Benefits. Carruthers’ current group health benefit coverage for health care, dental, life insurance and vision care benefits will continue, to the extent permitted by the carriers, until the earlier of the Termination Date or the date on which Carruthers becomes eligible for benefit coverage through a subsequent employer, subject to any revisions to the plans that are made generally in respect of benefits for executives of the Company. Eligibility for Grainger’s Executive Physical Examination Program shall remain available to Carruthers for the years 2015 and 2016. All other benefit coverage and Carruthers’ eligibility to participate in any other Company employee programs end on the Separation Date.

Pension Plan. The Company will, consistent with its past practice and subject to Carruthers continuing his contributions, continue its contributions to the defined contribution pension plan to the earlier of the Termination Date or the date on which Carruthers becomes eligible for membership in a pension plan through a subsequent employer. Carruthers will be contacted by the plan administrator after his participation ends regarding his options under the pension plan.

Notional Account Plan. To the extent permissible, the Company will continue to make notional contributions based on the eligible portion of the Separation Payments for the period ending on the Termination Date in accordance with the provisions of the Acklands-Grainger Inc. Notional Account Plan for Designated Executives and Senior Managers. Receipt of any Notional Account balance shall occur pursuant to the provisions of the Notional Plan. So as to insure compliance with U.S. Section 409-a, Carruthers will receive payment of all funds contained within his Notional Account 6 months after his Termination Date.

Expatriation - Long Term International Assignment. The terms of the repatriation engagement letter dated December 22, 2011, with the exception of the tax equalization provisions, shall continue to apply up to the Separation Date. Tax equalization provisions will apply to all payments pursuant to the terms of this Agreement. Should Carruthers elect to be repatriated to Canada prior to the Separation Date, the repatriation provisions of the repatriation engagement letter will be honoured. Should Carruthers return to Canada after his Separation Date but prior to September 30, 2016, Grainger will provide Carruthers with a sum, up to $25,000 against invoices for purposes of the movement of household goods between the United States and Canada.

Stock Options and Performance Share Units. Carruthers will be eligible to exercise all vested stock options pursuant to the terms of the W.W. Grainger, Inc. 2010 Incentive Plan and companion agreements. Applicable Options and Performance Share Units (i.e. awarded in 2012, 2013 and 2014) will continue to vest through the Termination Date, with any remaining unvested options or units forfeiting as of the Termination Date. Thereafter, all then vested options must be exercised on or before the expiration date of each option or within three (3) months of the Termination Date, whichever should occur first. The Special January 1, 2014 PRSU Grant shall vest by operation of this Agreement as of January 1, 2017. Performance Shares issued in 2013, 2014 and 2015 will vest by operation of this Agreement. Carruthers further understands and agrees that the non-competition provisions of performance share, restricted stock unit and/or stock option agreements to which Carruthers is a party, which provisions are incorporated herein by reference, including without limitation the W.W. Grainger, Inc. Unfair Competition Agreement dated January 1, 2015, and the W.W. Grainger, Inc. Stock Option Agreement dated April 30, 2014 (collectively, the "non­competition provisions"), will remain in full force and effect, and are in addition to and not superseded by any other obligation set forth in this Agreement. Carruthers acknowledges and agrees that, for purposes of such agreements, his employment with the Company shall be considered terminated on the Termination Date hereunder, and the term "Date of Termination" as used in the Unfair Competition Agreement dated January 1, 2015, shall mean the Termination Date hereunder. Carruthers understands that he will not be eligible for any further grants of Stock Options or Performance Shares beyond those he has already received.
