Dear Henrik:

This letter agreement (this “Letter Agreement”) supplements the Amended and Restated Employment Agreement dated July 16, 2013 (the “Employment Agreement”), by and between you and ABM Industries Incorporated (the “Company”), and serves to set forth the terms and conditions for your Departure from the Company. You and the Company have entered into this Letter Agreement as of the date of the last signature to this Letter Agreement. Terms used in this Letter Agreement with initial capital letters that are not locally defined in this Letter Agreement are used in this Letter Agreement as defined in Section 13 of this Letter Agreement.

In consideration of the mutual promises contained in this Letter Agreement, the Company and you (“you”, “Executive”, or “he”) agree, effective as of January 12, 2015 (the “Effective Date”), as follows:

1. Departure from the Company.

(a) As of March 31, 2015 (the “March Date”), Executive will resign all positions he has held as an officer, director, and employee of the Company and its subsidiaries and affiliates, and will promptly execute such documents and take such actions as may be necessary or reasonably requested by the Company to effectuate or memorialize the resignation from such positions. Executive acknowledges and agrees that his service as an employee of the Company through the March Date satisfies any 90-day notification requirement under the Employment Agreement. The Company acknowledges that Executive will incur a “separation from service” at the close of business on the March Date for purposes of Treasury Regulation Section 1.409A-1(h).

(b) After the March Date, Executive will serve up to eight hours per week as a consultant to the Company, with the title of “Senior Advisor.” As Senior Advisor, Executive’s duties and responsibilities shall consist of (i) assisting and advising the successor Chief Executive Officer with transition matters, including relationships with customers, industry peers, employees and labor unions, and (ii) assisting the Board of Directors of the Company (the “Board”) and the successor Chief Executive Officer with the evaluation of strategic opportunities and initiatives. He shall make himself available to perform such duties at the principal offices of the Company or by telephone

000 Xxxxx Xxxxxx, Xxxxx 000 Xxx Xxxx, X.X. 00000 Office: (000) 000-0000 Fax: (000) 000-0000

at such times during regular business hours as reasonably requested by the successor Chief Executive Officer or the Board. As Senior Advisor, Executive will be acting as an independent contractor and not as an employee of the Company. Subject to Section 1(c), Executive will serve as Senior Advisor on an at-will basis through September 30, 2015 (the “September Date”) under the terms of this Letter Agreement. This period, as extended by Section 1(c) if applicable, shall be referred to as the “Transition Period.” During the Transition Period, Executive’s service with the Company may be terminated by either the Company or Executive, either with or without “Just Cause” (as such term is defined in the Employment Agreement). In the event that Executive is terminated with or without Just Cause during the Transition Period, Executive shall only be entitled to compensation through his last day of service. At the end of the Transition Period, or the last day of service if terminated earlier, the “Transition End Date”, Executive will cease to have the title of “Senior Advisor” and his service with the Company shall terminate.

(c) The parties agree that Executive and the Company may opt to extend Executive’s service with the Company as a Senior Advisor beyond the September Date for an additional period of between three and six months, provided, that such an extension shall be subject to the mutual agreement of the parties.

2. Severance Under The Employment Agreement and Certain Payments, Benefits, and New Consideration.

(a) Executive will be deemed to have been terminated by the Company without Just Cause pursuant to Paragraph 15(D) of the Employment Agreement as of the March Date. As such, Executive shall be entitled to the payments and benefits specified in Paragraph 15(D) of the Employment Agreement, including an amount equal to two times the sum of Executive’s current base salary and current target annual incentive opportunity of $888,666 under the Company’s annual performance incentive program, payable in substantially equal installments over 24 months commencing with April, 2015, subject to Executive’s execution between April 1 and 21, 2015 and non-revocation of the release attached hereto as Exhibit A, which shall be in addition to the release set forth in Section 4 of this Letter Agreement. The payments described in the preceding sentence shall not be deferred by reason of Executive being a “specified employee” pursuant to Section 409A of the Internal Revenue Code of 1986, as amended (the “Code”). Per the terms of the Employment Agreement, Executive’s rights under that certain Change-in-Control Agreement between Executive and the Company, dated December 30, 2008, shall terminate as of the March Date and be of no further force and effect.

In the event that Executive dies prior to the expiration of such ten-year period, the Company shall pay Executive’s surviving spouse $10,000 per year
