                                      -4-
<PAGE>

     evidenced by an Agreement between the recipient and the Company containing
     the terms and conditions of the Option.

          (b)  Option Price. The Exercise Price of Common Stock issued pursuant
     to each Option shall be equal to the Fair Market Value of the Common Stock
     as of the end of the fiscal year immediately preceding the Award Date.

          (c)  Term of Option. No Option shall be exercisable more than ten
     years after the date the Option is granted.

          (d)  Vesting. Options granted under the Plan shall vest six months
     after the date of grant.

          (e)  Exercise. Options, to the extent they are vested, may be
     exercised in whole or in part at any time during the option period;
     provided, however, that an option may not be exercised at any time for
     fewer than 100 shares (or the total remaining shares covered by the Option
     if fewer than 100 shares) during the term of the Option. The specified
     number of shares will be issued upon receipt by the Company of (i) notice
     from the optionee of exercise of an Option, and (ii) payment to the Company
     (as provided in (f) below) of the Exercise Price for the number of shares
     with respect to which the Option is exercised. Each such notice and payment
     shall be delivered or mailed by postpaid mail, addressed to the Treasurer
     of the Company at AECOM Technology Corporation, 3250 Wilshire Blvd., Los
     Angeles, California 90010, or such other place as the Company may designate
     from time to time.

          (f)  Payment for Shares. The Exercise Price for the Common Stock shall

     paid in whole or in part (i) in cash, (ii) in whole shares of Common Stock
     owned by the Director six months or longer and evidenced by negotiable
     certificates, valued at their Fair Market Value on the date of exercise,
     (iii) by a combination of such methods of payment, or (iv) in such other
     form or in such other manner as the Committee may determine. In addition, a
     Director may exercise the Option by effecting a "cashless exercise" of the
     Option; that is providing assurance from a broker registered under the
     Exchange Act, of the delivery of the proceeds of an imminent sale of the
     stock to be issued pursuant to the exercise of such Option, such sale to be
     made at the direction of the Director.

          (g)  Termination. If a Director's service on the Board terminates by
     reason of (i) normal retirement from the Board at age 72, (ii) the death or
     total and permanent disability within the meaning of Section 22(e)(3) of
     the Code of such Director, (iii) an Event, or (iv) voluntary early
     retirement to take a position

                                      -5-
<PAGE>

     in governmental service, any Option held by such Director may thereafter be
     exercised by the Director, or in the event of death by his or her
     Beneficiary, to the extent it was vested and exercisable at the time of
     termination (i) for a period equal to the number of years of completed
     Board service as of the date of termination of the Director on whose behalf
     the Option is exercised, or (ii) until the expiration of the stated term of
     such Option, whichever period is the shorter. In the event of termination
     for any reason other than those set forth above, any Option held by such
     Director may thereafter be exercised by the Director to the extent it was
     vested and exercisable at the time of termination (i) for a period of one
     year from the date of such termination or (ii) until the expiration of the
     stated term of such Option, whichever period is the shorter.
          (h)  Term. No Option shall be granted pursuant to the Plan on or after
     the tenth anniversary of the effective date of this Plan, but Option awards
     granted prior to such tenth anniversary may extend beyond that date until
     the expiration of their terms.


                     ARTICLE III.  MISCELLANEOUS PROVISIONS
                     --------------------------------------

1.   BENEFICIARY DESIGNATION
     -----------------------

     A Director may designate any person to whom payments are to be made if the
     Director dies before receiving payment of all amounts due hereunder.  A
     designation of Beneficiary will be effective only after the signed Election
     is filed with the Secretary of the Company while the Director is alive and
     will cancel all designations of a Beneficiary signed and filed earlier.  If
     the Director fails to designate a Beneficiary as provided above, remaining
     unpaid amounts shall be paid to the estate of such Director.  If all
     Beneficiaries of the Director die before the Director or before complete
     payment of all amounts due hereunder, the remaining unpaid amounts shall be
     paid to the estate of the last to die of such Beneficiaries.

2.   INALIENABILITY OF BENEFITS
     --------------------------

     The interests of the Directors and their Beneficiaries under the Plan may
     not in any way be voluntarily or involuntarily transferred, alienated or
     assigned, nor be subject to attachment, execution, garnishment or other
     such equitable or legal process. Any Option shall be exercisable, during a
     Director's lifetime, only by him or her or his or her Personal
     Representative.

3.   GOVERNING LAW
     -------------

                                      -6-
<PAGE>

     The provisions of this Plan shall be interpreted and construed in
     accordance' with the laws of the State of California, without giving effect
     to the doctrine of conflict of laws.

4.   AMENDMENTS
     ----------

     The Committee may amend, alter or terminate this Plan at any time without
     the prior approval of the Directors. The Company, with the consent of the
     Participant, may make such modifications of the terms and conditions of
     such Participant's Options as it shall deem advisable. No Options may be
     granted during any suspension of this Plan or after its termination. The
     amendment, suspension or termination of this Plan shall not, without the
     consent of the Participant, alter or impair any rights or obligations
     pertaining to any Awards granted under this Plan prior to such amendment,
     suspension or termination.

5.   COMPLIANCE WITH RULE 16b-3
     --------------------------

     It is the intention of the Company that the Plan comply in all respects
     with Rule 16b-3 promulgated under Section 16(b) of the Exchange Act to the
     extent that such Rule is applicable to the Company and that Plan
     participants remain disinterested persons ("Disinterested Persons") for
     purposes of administering other employee benefit plans of the Company and
     having such other plans be exempt from Section 16(b) of the Exchange Act.
     Therefore, if any Plan provision is found not to be in compliance with Rule
     16b-3 or if any Plan provision would disqualify Plan participants from
     remaining Disinterested Persons, that provision shall be deemed amended so
     that the Plan does so comply and the Plan participants remain
     disinterested, to the extent permitted by law and deemed advisable by the
     Committee, and in all events the Plan shall be construed in favor of its
     meeting the requirements of Rule 16b-3.

6.   EFFECTIVE DATE
