     -------------------------

     AECOM Technology Corporation hereby establishes the AECOM Technology

     For all purposes of this Plan, capitalized terms, unless defined herein,
     shall have the meanings specified in the AECOM RSP, unless a different
     meaning is plainly required by the context.

     forth below, unless a different meaning is plainly required by the context.

          with amounts as provided in Article Two.

     (b)  "AECOM RSP" means the AECOM Technology Corporation Retirement &
          Savings Plan (formerly called the Employee Stock Ownership Plan) as in
          effect on the Effective Date and as such plan may be amended from time
          to time.

          may be required under applicable law) each of whom shall, to the
          extent required by applicable law, be "non-employee directors" within
          the meaning of applicable regulatory requirements, including those
          promulgated under Section 16 of the Securities Exchange Act of 1934

                           Participation and Credits
                           -------------------------

2.1  Participation
     -------------

     (a)  (i)    An Eligible Employee may irrevocably authorize the pre-tax
          deferral (in whole percentages up to 50%, unless otherwise determined
          by the Committee, for any payroll period) of cash Compensation under
          this Plan. Notwithstanding any provision of the Plan to the contrary,
          the authorization of an Eligible Employee to make deferrals under this
          Section 2.1(a)(i) shall only apply, and deferrals shall only be made,
          during periods when the Company determines that the Eligible Employee
          may not make tax deferred contributions to the AECOM RSP because of
          one or more of the following limits: (1) the discrimination tests
          under Section 401(k) and (m) of the Code, (2) the limitations on tax
          deferred contributions to qualified plans under Section 402(g) of the
          Code, (3) the limitation on compensation taken into account in
          qualified plans under Section 401(a)(17) of the Code, or (4) any rule
          imposed by the Company (as administrator of the AECOM RSP) designed to
          meet any of the foregoing limits, which rule may be imposed by
          considering all Eligible Employees in the aggregate for purposes of
          meeting one or more of such limits. Such authorization shall continue
          until the Company determines that such Eligible Employee may again
          make tax deferred contributions to the AECOM RSP.

          (ii)   In addition to deferrals permitted under Section 2.1(a)(i), an
          Eligible Employee may also irrevocably authorize pre-tax contributions
          (in whole percentages up to 100%) of any Compensation paid in the form
          of the Company's Common Stock in lieu of cash or other incentive
          Compensation and/or a combination of these forms of compensation,
          whether such Compensation is paid at the direction of the Company or
          at the election of the Eligible Employee.  Such authorization under
          this Section 2.1(a)(ii) shall commence on the Eligible Employee's
          Eligibility Date.

          (iii)  A Director may irrevocably authorize the pre-tax deferral of
          all or any part of any director's fees or meeting fees that the
          Director is entitled to receive from the Company.

          (iv)   To be effective, the authorization of any Eligible Employee
          under Section 2.1(a)(i) or (ii), or of any Director under Section
          2.1(a)(iii), must be submitted to the Committee on the appropriate
          enrollment form before the Eligible Employee's or Director's
          Eligibility Date. Notwithstanding Section 2.1(a)(i) or (ii), such
          authorization will not continue in effect after the date the
          Participant terminates employment with the Company. Any authorization
          form submitted for a Plan Year shall continue to apply to future Plan
          Years unless the Eligible Employee or Director files a new election
          (or in the case of an Eligible Employee or Director who did not
          previously file an election, a first election) with the Committee
          before the beginning of the future Plan Year, in which case it the new
          election shall apply.

                                       4
<PAGE>

          (v)    Participants shall be entitled to credits to a Supplemental
          Compensation Deferral Account pursuant to Section 2.2 for amounts the
          Participant elects to have contributed on a pre-tax basis.

          (vi)   Notwithstanding anything contained herein to the contrary, no
          election to defer Compensation hereunder shall be effective to reduce
          the Compensation paid to an Eligible Employee for a calendar year to
          an amount that is less than the amount that the Participating Employer
          is required to withhold from such Eligible Employee's Compensation for
          such calendar year for purposes of federal, state and local (if any)
          income tax and employment tax (including Federal Insurance
          Contributions Act (FICA) tax withholding).

     (b)  An Eligible Employee or Director shall become a Participant under this
          Plan when an Account on his behalf is first credited hereunder.

     (c)  In-Service Distribution Elections.  At the time of submitting an
          ---------------------------------
          initial enrollment form pursuant to Section 2.1(a)(iv), a Participant
          may elect (in the manner specified by the Committee) to receive an in-
          service distribution of the cash amount or Common Stock Units credited
          to the Participant's Account pursuant to Section 2.2 for the first
          full or partial Plan Year of participation, together with interest or
          earnings or losses credited with respect to such amounts pursuant to
          Section 2.3, in a lump sum payment in any January that occurs after
          the second anniversary of the last day of such Plan Year.  Thereafter,
          a Participant may elect to receive an in-service distribution of the
          amounts credited to the Participant's Account pursuant to Section 2.2
          for any particular Plan Year, together with interest or earnings or
          losses, in a lump payment in any January that occurs after the fourth
          anniversary of the last day of such Plan Year by filing an election,
          on a form provided and in a manner specified by the Committee no later
          than December 15 of the preceding Plan Year (or such later date as the
          Committee designates, but in all events no later than December 31 of
          the preceding Plan Year).  If a Participant fails to make an in-
          service distribution election under this Section 2.1(c) for a
          particular Plan Year, the amounts credited to the Participant's
          Account pursuant to Section 2.2 for that Plan Year shall be
          distributed as set forth in Section 3.1(b).  Any election made under
          this Section 2.1(c) shall be irrevocable.

2.2  Credits to Supplemental Compensation Deferral Account
     -----------------------------------------------------

     (a)  Deferrals authorized to be credited on behalf of a Participant
          pursuant to Section 2.1(a) above shall be credited by the Company to
          the Participant's Supplemental Compensation Deferral Account. Such
          credits shall be made as of the date on which the amount being
          credited would have been paid to the Participant, but for the
          authorization of the Participant under Section 2.1(a).

     (b)  In addition to the crediting deferrals authorized pursuant to Section
          2.1(a), the Company may credit to the Participant's (or Eligible
          Employee's, if the person is not already a Participant) Supplemental
          Compensation Deferral Account any

                                       5
<PAGE>

          additional cash amounts or Common Stock Units which the Company has
          determined, for any reason, to credit to such Participant.

     (c)  If a Participant makes one or more in-service distribution elections
          pursuant to Section 2.1(c), the Committee shall, to the extent
          necessary, separately track the Common Stock Units that are subject to
          each in-service distribution election providing a different payout
          date.  Such separate amounts shall be referred to as Plan Year
          Subaccounts.

2.3  Accounts and Interest Equivalents
     ---------------------------------

     (a)  Participants' Accounts.  The Company shall establish a Supplemental
          ----------------------
          Compensation Deferral Account for each Participant to determine the
          amount payable on behalf of the Participant under the Plan.

     (b)  Common Stock Units.  Cash amounts credited to each Participant's
          ------------------
          Account under the Plan shall be converted into a number of Common
          Stock Units by dividing the cash amount in each Account by the fair
          market value of a share of Common Stock of the Company.  For this
          purpose, cash amounts credited to a Participant's Account shall be
          converted to Common Stock Units based upon the value of the Common
          Stock as determined in a manner consistent with the valuation of such
          stock under the AECOM RSP.

     (c)  Dividends.  At any time that the Company issues a cash or stock
          ---------
          dividend with regard to its Common Stock, an amount shall be credited
          to each Participant's Account under the Plan equal to the dividends
          that would be payable if the Common Stock Units in the Participant's
          Account constituted outstanding shares of Common Stock of the Company.
          Amounts so credited to Participants' Accounts shall be converted into
          Common Stock Units in accordance with the provisions of Section
          2.3(b).

     (d)  Adjustments.  If the outstanding shares of the Company's Common Stock
          -----------
          are increased, decreased or changed into, or exchanged for, a
          different number or kind of shares or securities of the Company
          through a reorganization or merger in which the Company is the
          surviving entity, or through a combination, recapitalization,
          reclassification, stock split, stock dividend, stock consolidation or
          otherwise, an appropriate adjustment shall be made in the number and
          kind of Common Stock Units that are credited to each Participant's
          Account under the Plan.

     (e)  Statements.  Each Participant shall receive a statement of the balance
          ----------
          in his or her Account at least annually.

2.4  Vesting
     -------

     Each Participant shall be one hundred percent vested, at all times, in the
     value of his Supplemental Compensation Deferral Account.

                              -------------------

3.1  Commencement and Form of Payment
     --------------------------------

     (a)  Scheduled In-Service Distribution.
          ---------------------------------

          (i)  The amounts credited to each of the Participant's Plan Year
          Subaccounts that are subject to an in-service distribution election
          made by the Participant pursuant to Section 2.1(c) above shall be
          distributed in January of the year elected by the Participant,
          provided that the Participant is employed by a Participating Company
          on the date that the distribution is scheduled to be made.

          (ii) If the Participant's employment with all Participating Employers
          is terminated for any reason prior to the commencement of a scheduled
          in-service distribution for a Plan Year Subaccount pursuant to
          subsection (i) above, the Participant's in-service distribution
          election for such Plan Year Subaccount shall no longer be effective
          and all of the amounts credited to such Plan Year Subaccount shall be
          distributed as set forth in the following subsections of this Section
          3.1 in accordance with any applicable election by the Participant.

     (b)  Payment at Termination of Employment.
          ------------------------------------

          (i)  As soon as practicable following each Participant's termination
          of employment with all Participating Employers, the Participating
          Employer by which the Participant was last employed shall pay to such
          Participant, or, if such Participant is not living at the time for
          payment, to such Participant's Beneficiary, the amount then credited
          to the Participant's Account in a lump sum as soon as practicable
          after termination of employment. An Eligible Employee who terminates
          employment with a Participating Employer shall be treated under the
          Plan as a terminated Eligible Employee without regard to whether he or
          she becomes a Director upon or after ceasing to be an Eligible
          Employee. A Director shall be deemed to have "terminated employment"
          and be entitled to distribution of the amount then credited to his
          Account on the date that he ceases to be a member of the Board.

          (ii) Notwithstanding the foregoing, a Participant may elect to receive
          such distribution in substantially equal annual installments over five
          or ten years beginning as soon as practicable following termination of
          employment, provided that such election is made at least one year
          prior to his termination of employment on a form provided and in a
          manner specified by the Committee.  A Participant may change the form
          of distribution, provided that his change of election is made on a
          form and in a manner specified by the Committee and such election is
          received by the Committee at least one year prior to the Participant's
          termination of employment.

<PAGE>

     (c)  Form of Payment.
          ---------------

          Unless otherwise determined by the Committee, payments of a
          Participant's Account shall be made in actual shares of Common Stock
          of the Company in a number equal to the number of Common Stock Units
          then payable, with any fractional Common Stock Units to be settled by
          a cash payment.

3.2  Loans and In-service Payments and Withdrawals
     ---------------------------------------------

     No Participant shall be allowed to borrow from the Plan.  Except as
     provided in Section 2.1(c) and 3.1(a), no withdrawal or payment of benefits
     shall be allowed before a Participant terminates employment with the
     Company.

     The Committee shall be solely responsible for the operation and
     administration of the Plan and shall have all powers described in the AECOM

     power to determine whether a dollar credit should be made on behalf of a
     Participant, the amount of the dollar credit, and the number of Common
     Stock Units into which such dollar credits are converted.  The Committee
     shall have full discretion to construe and interpret the terms and
     provisions of this Plan, which interpretation or construction shall be
     final and binding on all parties, except as otherwise provided by law.

5.1  Amendment
     ---------

     The Company reserves the right at any time and from time to time, and

                            Miscellaneous Provisions
                            ------------------------

6.1  Source of Payments
     ------------------

     The Plan shall not be funded and all payments hereunder to Participants or
     Beneficiaries shall be paid from the general assets of each Participating
     Employer, except to the extent paid by the Trust provided for below.  No
     Participating Employer shall, by virtue of any provisions of the Plan or by
     any action of any person, be deemed to be a trustee or other fiduciary of
     any property for any Participant or Beneficiary, and the liabilities of
     each Participating Employer to any Participant or Beneficiary pursuant to
     the Plan shall be those of a debtor pursuant only to such contractual
     obligations as are created by the Plan; no such obligation of a
     Participating Employer shall be deemed to be secured by any pledge or other
     encumbrance on any property of such Participating Employer.  To the extent
     that any Participant or Beneficiary acquires a right to receive payment
     from a Participating Employer under the Plan, such right shall be no
     greater than the right of an unsecured general creditor of the
     Participating Employer.

     Notwithstanding the foregoing, the Company may create and fund a "rabbi
     trust" (the "Trust") with respect to this Plan.  The creation and funding
     of said Trust shall not create a security interest in the property of such
     Trust in favor of Participants or Beneficiaries or otherwise cause a
     funding of the Plan or Trust in any manner inconsistent with the preceding
     paragraph or Section 6.8.  The amount of any contributions to such Trust
     shall be totally discretionary as determined by the Company.  Any amount
     paid from such Trust to the Participant shall reduce the amount to be paid
     pursuant to this Plan by the Participating Employer.  In the event the
     amounts paid from the Trust are insufficient to provide the full benefits
     payable to the Participant under this Plan, the Participating Employer
     shall pay the remainder of such benefit in accordance with the terms of
     this Plan.

     It is the intention of the Participating Employers that this Plan and Trust
     be considered unfunded for purposes of the Code and Title 1 of ERISA.

6.2  General Provisions
     ------------------

     (a)  This Plan and the issuance or transfer of shares of Common Stock
          (and/or the payment of money) pursuant thereto are subject to all
          applicable Federal and state laws, rules and regulations, to the
          rights, preferences, limitations, and restrictions set forth in the
          Company's Certificate of Incorporation and Bylaws, and to such
          approvals by any regulatory or governmental agency (including without
          limitation "no action" positions of the Securities and Exchange
          Commission) which may, in the opinion of counsel for the Company, be
          necessary or advisable in connection therewith.  Without limiting the
          generality of the foregoing, no shares shall be issued by the Company,
          nor cash payments made by the Company, unless and until all legal
          requirements applicable to the issuance or payment have, in the
          opinion of counsel to the Company, been complied with.  In connection
          with any stock issuance or transfer, the person acquiring the shares
          shall, if requested by

                                      11

<PAGE>

          the Company, give assurances satisfactory to counsel to the Company in
          respect to such matters as the Company may deem desirable to assure
          compliance with all applicable legal requirements and the Company's
          Certificate of Incorporation and Bylaws.

     (b)  The Committee may specify such provisions as it deems appropriate for
          payment under the Plan upon the occurrence of any of the following
          events (each a "Corporate Event"):

          (i)   Approval by the stockholders of the Company of the dissolution
                or liquidation of the Company;

          (ii)  Approval by the stockholders of the Company of an agreement to
                merge or consolidate, or otherwise reorganize, with or into one
                or more entities of which less than 50% of the outstanding
                voting securities of the surviving or resulting entity are, or
                are to be, owned by former stockholders of the Company
                (excluding from the term "former stockholders" a stockholder who
                is, or as a result of the transaction in question becomes, an
                "affiliate," as that term is used in the Act and the Rules
                promulgated thereunder, of any party to such merger,
                consolidation or reorganization); or

          (iii) Approval by the stockholders of the Company of the sale of
                substantially all of the Company's business and/or assets to a
                person or entity that is not a subsidiary.

     For purposes of this paragraph (b), the term "subsidiary" shall mean any
     corporation or other entity a majority or more of whose outstanding voting
     stock or voting power is beneficially owned directly or indirectly by the
     Company.

6.3  Inalienability of Benefits
     --------------------------

     No benefit payable under, or interest in, the Plan shall be subject in any
     manner to anticipation, alienation, sale, transfer, assignment, pledge,
     encumbrance, or charge, and any attempt to do so shall be void.  Any such
     benefit or interest shall not in any manner be liable for or subject to
     garnishment, attachment, execution, or levy or liable for or subject to the
     debts, contract, liabilities, engagements, or torts of any Participant or
     Beneficiary.  If the Committee finds that any Participant or Beneficiary
     has become bankrupt or that any attempt has been made to anticipate,
     alienate, sell, transfer, assign, pledge, encumber, or charge any benefit
     payable under, or interest in, the Plan, the Committee shall hold or apply
     such benefit or interest or any part thereof to or for the benefit of such
     Participant or Beneficiary.

6.4  Expenses
     --------

     Each Participating Employer shall pay all costs and expenses incurred in
     operating and administering the Plan attributable to that Participating
     Employer; provided that the

                                      12
<PAGE>

     Company may in its discretion pay some or all costs and expenses of a
     Participating Employer.

6.5  No Right of Employment
     ----------------------

     Nothing contained herein nor any action taken under the provisions hereof
     shall be construed as giving any Participant the right to be retained in
     the employ of any Participating Employer.

6.6  Withholding
     -----------

     Each Participating Employer shall withhold from any payment hereunder any
     required amount of income and other taxes.

6.7  Headings
     --------

     The headings of the sections in the Plan are placed herein for convenience
     of reference; in the case of any conflict, the text of the Plan, rather
     than such heading, shall control.

6.8  Construction
     ------------

     Except to the extent governed by federal law, the Plan shall be construed,
     regulated, and administered in accordance with the laws of the State of
     California.  If any provision shall be held by a court of competent
     jurisdiction to be invalid and unenforceable, the remaining provisions of
     this Plan shall continue to be fully effective.  To the extent that the
     Plan is subject to the provisions of the Employee Retirement Income
     Security Act of 1974, as amended, ("ERISA") it is intended to be an
     unfunded deferred compensation plan "for a select group of management or
     highly compensated employees."  It is also intended that the Plan
     constitute an excess plan, as defined by ERISA.  Each provision of the Plan
     shall be administered, interpreted and construed to carry out such
     intention, and any provision that cannot be so administered, interpreted
     and construed shall, to that extent, be disregarded.

          IN WITNESS WHEREOF, the Company has caused this Plan to be executed
this _________ day of ___________, 2002.
