The Plan

2.1 Name. This Plan shall be known as the “ABM Industries Incorporated Executive Stock Option Plan”.

2.2 Purpose. The purpose of the Plan is to advance the interests of the Company and its shareholders by affording to Nonemployee Directors and to key management employees of the Company and its Subsidiaries an opportunity to acquire or increase their proprietary interest in the Company by the grant to such individuals of Options under the terms set forth herein. By thus encouraging such individuals to become owners of the Company shares, the Company seeks to motivate, retain, and attract those highly competent individuals upon whose judgment, initiative, leadership, and continued efforts the success of the Company in large measure depends.

Effective December 9, 2003, no additional Options shall be granted under the Plan. Each Nonemployee Director who both (1) is such on the date of the 1995 Annual Meeting of Stockholders, and (2) does not hold an Option, automatically shall receive as of such date only, an Option to purchase 12,000 shares of Stock, but subject to Section 6.2 (regarding the ineligibility of 10 percent ((10%) holders). Each Nonemployee Director who becomes such after the 1995 Annual Meeting of Stockholders and prior to December 9, 2003, automatically shall receive, as of the date of his or her election or appointment to the Board, an Option to purchase 12,000 shares of Stock.

6.2 Participant Limitation. The Committee shall not grant an Option to any individual for such number of shares of Stock that, immediately after the grant, the total number of shares of Stock owned or subject to all options exercisable at any time by such individual exceed ten percent (10%) of the total combined voting power of all Stock of the Company or its Subsidiaries. For this purpose an individual shall be considered as owning stock owned, directly or indirectly, by or for his brothers and sisters (whether by the whole or half blood), spouse, ancestors, and lineal descendents, and stock owned, directly or indirectly, by or for a corporation, partnership, estate, or trust shall be considered as being owned proportionately by or for its shareholders, partners, or beneficiaries.

The per share Option price of the Stock subject to each Option shall be determined by the Committee, but the per share price shall not be less than the Fair Market Value of the Stock on the date the Option is granted.

6.4 Period of Exercisablity. Subject to Sections 6.5 (a) and 6.7, the period during which each Option may be exercised shall be determined in accordance with the following rules. As to the first fifty percent (50%) of the shares covered by an Option, the Option may be exercised during the period commencing on the Optionee’s Initial Vesting Date and ending one (1) year after the Optionee’s termination of employment with the Company and all of its Subsidiaries (termination from the Board, in the case of Nonemployee Director).

As to the remaining fifty percent (50%) of the shares covered by the Option, the Option may be exercised during the period commencing on the Optionee’s Final Vesting Date and ending one (1) year after the Optionee’s termination of employment with the Company and all of its Subsidiaries (termination from the Board, in the case of a Nonemployee Director).

6.5 Option Exercise.

(a) Options granted hereunder may not be exercised unless the Optionee shall have remained in the employ of the Company or its Subsidiaries (on the Board in the case of a Nonemployee Director) until the applicable Vesting Date.

(b) Options may be exercised in whole or in part from time to time with respect to whole shares only, during such period for the exercise thereof, and shall be exercised by written notice of exercise with respect to a specified number of shares delivered to the Company at its headquarters office, and payment in full to the Company at said office of the amount of the Option price for the number of shares of Stock with respect to which the Option is exercised. The Option exercise price shall be payable in cash or, in the discretion of the Committee, in shares of Stock or a combination of cash and shares of Stock. In addition to and at the time of payment of the Option price, Optionee shall pay to the Company in cash or, in the discretion of the Committee, in shares of Stock or a combination of cash and shares of Stock, the full amount of all applicable withholding taxes applicable to the taxable income of such Optionee resulting from such exercise.

Notwithstanding the foregoing, an Optionee may designate a Beneficiary to succeed, after the Optionee’s death, to all of the Optionee’s Options outstanding on the date of death.

In the event of a Change in Control, the surviving, continuing, successor, or purchasing Company or other business entity or parent thereof, as the case may be (the “Acquiror”) may, without the consent of any Optionee, either assume or continue the Company’s rights and obligations under outstanding Options or substitute for outstanding Options substantially equivalent options covering the Acquiror’s stock. All options assumed or continued by the Acquiror in connection with a Change in Control will become fully vested and exercisable if, during the 12-month period following the Change in Control, the Optionee’s employment is terminated without Cause or, in the case of a Nonemployee Director, the Optionee’s service to the Company as a Director is terminated. Any Options that are neither assumed nor continued by the Acquiror in connection with the Change in Control shall, contingent on the Change in Control, become fully vested and exercisable immediately prior to the Change in Control.

6.8 Effect of Termination of Employment or Service. Subject to the provisions of Section 6.7 above, if, prior to an Optionees applicable Vesting Date, the Optionee’s employment or service shall be terminated by the Company or a Subsidiary with or without Cause, or by the act of the Optionee, the right to exercise such Option (or portion thereof) shall terminate and all rights thereunder shall cease.
