the right to vote may vote in person or may authorize another person or persons
to act for him by proxy appointed by an instrument in writing subscribed by such
stockholder and bearing a date not more than three years prior to said meeting,

with the Secretary of the Corporation at the beginning of each meeting in order
to be counted in any vote at the meeting. Each stockholder shall have one vote

Corporation shall prepare and make, at least ten days before every meeting of
stockholders, a complete list of the stockholders entitled to vote at the
meeting, arranged in alphabetical order, and showing the address of each
stockholder and the number of shares registered in the name of each stockholder.
Such list shall be open to the examination of any stockholder, for any purpose
germane to the meeting, during ordinary business hours, for a period of a least
ten days prior to the meeting, either at a place within the city where the
meeting is to be held, which place shall be specified in the notice of the
meeting, or, if not so specified, at the place where the meeting is to be held.
The list shall also be produced and kept at the time and place of the

<PAGE>

meeting during the whole time thereof, and may be inspected by any stockholder
who is present.

      Section 9. Unless otherwise provided in the Certificate of Incorporation,
any action required to be taken at any annual or special meeting of stockholders
of the Corporation, or any action which may be taken at any annual or special
meeting of such stockholders, may be taken without a meeting, without prior
notice and without a vote, if a consent in writing, setting forth the action so
taken, shall be signed by the holders of outstanding stock having not less than
the minimum number of votes that would be necessary to authorize or take such
action at a meeting at which all shares entitled to vote thereon were present
and voted. Prompt notice of the taking of the corporate action without a meeting

time to time by resolution of the Board of Directors, provided that the Board of
Directors shall consist of at least one member. The directors need not be

stockholders, except as provided in Section 2 of this Article, and each director
elected shall hold office until his successor is elected and qualified;
provided, however, that unless otherwise restricted by the Certificate of
Incorporation or by law, any director or the entire Board of Directors may be
removed, either with or without cause, from the Board of Directors at any
meeting of stockholders by a majority of the stock represented and entitled to
vote thereat.

      Section 2. Vacancies on the Board of Directors by reason of death,
resignation, retirement, disqualification, removal from office, or otherwise,

number of directors may be filled by a majority of the directors then in office,
although less than a quorum, or by a sole remaining director. The directors then

directors so chosen shall hold office until the next annual election of
directors and until their successors are duly elected and shall qualify, unless
sooner replaced by a vote of the shareholders. If there are no directors in
office, then an election of directors may be held in the manner provided by
statute. If, at the time of filling any vacancy or any newly created
directorship, the directors then in office shall constitute less than a majority
of the whole Board (as constituted immediately prior to any such increase), the
Court of Chancery may, upon application of any stockholder or stockholders
holding at least ten percent of the total number of the shares at the time
outstanding having the right to vote for such directors, summarily order an
election to be held to fill any such vacancies or newly created directorships,
or to replace the directors chosen by the directors then in office.

      Section 3. The property and business of the Corporation shall be managed
by or under the direction of its Board of Directors. In addition to the powers
and authorities by these Bylaws expressly conferred upon them, the Board my

Board.

      Section 6. Special meetings of the Board of Directors may be called by the
Chairman of the Board or the President on forty-eight hours' notice to each
director, either personally or by mail or by telegram; special meetings shall be
called by the President or the Secretary in like manner and on like notice on
the written request of two directors.

      Section 7. At all meetings of the Board of Directors a majority of the
authorized number of directors shall be necessary and sufficient to constitute a
quorum for the transaction of business, and the vote of a majority of the
directors present at any meeting at which there is a quorum, shall be the act of
the Board of Directors, except as may be otherwise specifically provided by
statute, by the Certificate of Incorporation or by these Bylaws. If a quorum
shall not be present at any meeting of the Board of Directors, the directors
present thereat may adjourn the meeting from time to time, without notice other
than announcement at the meeting, until a quorum shall be present. If only one
director is authorized, such sole director shall constitute a quorum. At any
meeting, a director shall have the right to be accompanied by counsel provided
that such counsel shall agree to any confidentiality restrictions reasonably
imposed by the Corporation.

      Section 8. Unless otherwise restricted by the Certificate of Incorporation
or these Bylaws, any action required or permitted to be taken at any meeting of
the Board of Directors or of any committee thereof may be taken without a
meeting, if all members of the Board or committee, as the case may be, consent
thereto in writing, and the writing or writings are filed with the minutes of
proceedings of the Board or committee.

      Section 9. Unless otherwise restricted by the Certificate of Incorporation
or these Bylaws, members of the Board of Directors, or any committee designated
by the Board of Directors, may participate in a meeting of the Board of
Directors, or any committee, by means of conference telephone or similar
communications equipment by means of which all persons participating in the
meeting can hear each other, and such participation in a meeting shall
constitute presence in person at such meeting.

      Section 10. The Board of Directors may, by resolution passed by a majority
of the whole Board, designate one or more committees, each such committee to
consist of one or more of the directors of the Corporation. The Board may
designate one or more directors as alternate members of any committee, who may
replace any absent or disqualified member at any meeting of the committee. In
the absence or disqualification of a member of a committee, the member or
members thereof present at any meeting and not disqualified from voting, whether
or not he or they constitute a quorum, may unanimously appoint another member of
the Board of Directors to act at the meeting in the place of any such

<PAGE>

absent or disqualified member. Any such committee, to the extent provided in the
resolution of the Board of Directors, shall have and may exercise all the powers
and authority of the Board of Directors in the management of the business and
affairs of the Corporation, and may authorize the seal of the Corporation to be
affixed to all papers which may require it; but no such committee shall have the
power or authority in reference to amending the Certificate of Incorporation,
adopting an agreement of merger or consolidation, recommending to the
stockholders the sale, lease or exchange of all or substantially all of the
Corporation's property and assets, recommending to the stockholders a
dissolution of the Corporation or a revocation of a dissolution, or amending the
Bylaws of the Corporation; and, unless the resolution or the Certificate of
Incorporation expressly so provide, no such committee shall have the power or
authority to declare a dividend or to authorize the issuance of stock.

      Section 11. Each committee shall keep regular minutes of its meetings and
report the same to the Board of Directors when required.

      Section 12. Unless otherwise restricted by the Certificate of
Incorporation or these Bylaws, the Board of Directors shall have the authority
to fix the compensation of directors. The directors may be paid their expenses,
if any, of attendance at each meeting of the Board of Directors and may be paid
a fixed sum for attendance at each meeting of the Board of Directors or a stated
salary as director. No such payment shall preclude any director from serving the
Corporation in any other capacity and receiving compensation therefor. Members
of special or standing committees may be allowed like compensation for attending
committee meetings.

      Section 13. The Corporation shall indemnify every person who is or was a
party or is or was threatened to be made a party to any action, suit, or
proceeding, whether civil, criminal, administrative or investigative, by reason
of the fact that he is or was a director or officer of the Corporation or, while
a director or officer or employee of the Corporation, is or was serving at the
request of the Corporation as a director, officer, employee, agent or trustee of
another corporation, partnership, joint venture, trust, employee benefit plan or
other enterprise, against expenses (including counsel fees), judgments, fines
and amounts paid in settlement actually and reasonably incurred by him in
connection with such action, suit or proceeding, to the full extent permitted by
applicable law.

                                 URS CORPORATION
                           1999 INCENTIVE EQUITY PLAN

              RESTRICTED STOCK AWARD AGREEMENT FOR MARTIN M. KOFFEL

      Pursuant to Section 4(b) of the Employment Agreement (as defined below),
the Restricted Stock Award Grant Notice ("Grant Notice") and this Restricted
Stock Award Agreement (collectively, the "Award"), and in consideration of your
past services, URS Corporation (the "Company") has awarded you a restricted
stock award under its 1999 Incentive Equity Plan (the "Plan") for the number of
shares of the Company's Common Stock subject to the Award indicated in the Grant
Notice. Except where indicated otherwise, defined terms not explicitly defined
in this Restricted Stock Award Agreement but defined in the Plan shall have the
same definitions as in the Plan.

      The details of your Award are as follows:

      1. VESTING. Subject to the limitations contained herein, your Award shall
vest as provided in the Grant Notice. Notwithstanding the foregoing, vesting of
your Award shall be accelerated both (i) in the circumstances provided in
Section 12(c) of the Plan and (ii) under the circumstances set forth in Section
6 below. The shares subject to your Award will be held by the Company until your
interest in such shares vests. As each portion of your interest in the shares
vests, the Company shall issue you a stock certificate covering such vested
shares.

      2. NUMBER OF SHARES. The number of shares subject to your Award may be
adjusted from time to time for Capitalization Adjustments, as provided in the
Plan.

      3. PAYMENT. This Award was granted in consideration of your past services
to the Company. You will not be required to make any payment to the Company with
respect to your receipt of the Award or the vesting thereof.

      4. SECURITIES LAW COMPLIANCE. You will not be issued any shares under your
Award unless the shares are either (a) then registered under the Securities Act
or (b) the Company has determined that such issuance would be exempt from the
registration requirements of the Securities Act. Your Award must also comply
with other applicable laws and regulations governing the Award, and you will not
receive such shares if the Company determines that such receipt would not be in
material compliance with such laws and regulations.

      5. TRANSFER RESTRICTIONS. Prior to the time that they have vested, you may
not transfer, pledge, sell or otherwise dispose of the shares subject to the
Award. For example, you may not use shares subject to the Award that have not
vested as security for a loan. In addition, you may not transfer, pledge, sell
or otherwise dispose of the shares subject to the Award that have vested at any
time when applicable securities laws or Company policies would prohibit such a
transfer. This restriction on the transfer of vested shares will lapse upon your
termination of Continuous Service. Notwithstanding the foregoing, you may, by
delivering written notice to the Company, in a form satisfactory to the Company,
designate a third party who, in the event of your death, shall thereafter be
entitled to receive vested shares as of the date of your death.

                                       1.

      6. TERMINATION OF CONTINUOUS SERVICE; ACCELERATION OF VESTING. In the
event your Continuous Service terminates for any reason, you will be credited
with the vesting that has accrued under your Award as of the date of your
termination of Continuous Service; provided, however, that the Award
automatically shall become vested in full as of the effective date of such
termination (i) if your Continuous Service terminates pursuant to any of clauses
(iv), (v) or (vi) of Section 6(a) of the employment agreement that you entered
into with the Company on September 5, 2003, as amended from time to time (the
"Employment Agreement"), or (ii) if such termination is the result of your death
or Disability (as such term is defined in your Employment Agreement).

      7. RESTRICTIVE LEGENDS. The shares issued under your Award shall be
endorsed with appropriate legends determined by the Company.

      8. RIGHTS AS A STOCKHOLDER. You shall exercise all rights and privileges
of a stockholder of the Company with respect to the shares subject to your
Award. You shall be deemed to be the holder of the shares for purposes of
receiving any dividends which may be paid with respect to such shares and for
purposes of exercising any voting rights relating to such shares, even if some
or all of such shares have not yet vested.

      9. AWARD NOT A SERVICE CONTRACT. Your Award is not an employment or
service contract, and nothing in your Award shall be deemed to (i) alter the
terms of your Employment Agreement or (ii) create in any way whatsoever any
obligation on your part to continue in the employ of the Company or any
affiliate thereof, or on the part of the Company or any affiliate thereof to
continue your employment or service. In addition, nothing in your Award shall
obligate the Company or any affiliate thereof, their respective stockholders,
boards of directors, officers or employees to continue any relationship that you
might have as a director or consultant for the Company or any affiliate thereof.

      10. WITHHOLDING OBLIGATIONS.

            (a) At the time your Award is made, or at any time thereafter as
requested by the Company, you hereby authorize withholding from payroll and any
other amounts payable to you, and otherwise agree to make adequate provision for
any sums required to satisfy the federal, state, local and foreign tax
withholding obligations of the Company or any affiliate thereof, if any, which
arise in connection with your Award. Such withholding obligations may be
satisfied by your relinquishment of your right to receive a portion of the
shares otherwise issuable to you pursuant to the Award; provided, however, that
you shall not be authorized to relinquish your right to shares with a fair
market value in excess of the amount required to satisfy the minimum amount of
tax required to be withheld by law.

            (b) Unless the tax withholding obligations of the Company and/or any
affiliate thereof are satisfied, the Company shall have no obligation to issue a
certificate for such shares or release such shares from any escrow provided for
herein.

      11. TAX CONSEQUENCES. The acquisition and vesting of the shares may have
adverse tax consequences to you that may be mitigated by filing an election
under Section 83(b) of the Code. Such election must be filed within thirty (30)
days after the date of the grant of

                                       2.

your Award. YOU ACKNOWLEDGE THAT IT IS YOUR OWN RESPONSIBILITY, AND NOT THE
COMPANY'S, TO FILE A TIMELY ELECTION UNDER CODE SECTION 83(B), EVEN IF YOU
REQUEST THE COMPANY TO MAKE THE FILING ON YOUR BEHALF.

      12. NOTICES. Any notices provided for in your Award or the Plan shall be
given in writing and shall be deemed effectively given upon receipt or, in the
case of notices delivered by the Company to you, five (5) days after deposit in
the United States mail, postage prepaid, addressed to you at the last address
you provided to the Company.

      13. MISCELLANEOUS.

            (a) The rights and obligations of the Company under your Award shall
be transferable to any one or more persons or entities, and all covenants and
agreements hereunder shall inure to the benefit of, and be enforceable by the
Company's successors and assigns. Your rights and obligations under your Award
may only be assigned with the prior written consent of the Company.

            (b) You agree upon request to execute any further documents or
instruments necessary or desirable in the sole determination of the Company to
carry out the purposes or intent of your Award.

            (c) You acknowledge and agree that you have reviewed your Award in
its entirety, have had an opportunity to obtain the advice of counsel prior to
executing and accepting your Award and fully understand all provisions of your
Award.

      14. GOVERNING PLAN DOCUMENT. Your Award is subject to all the provisions
of the Plan, the provisions of which are hereby made a part of your Award, and
is further subject to all interpretations, amendments, rules and regulations
which may from time to time be promulgated and adopted pursuant to the Plan. In
the event of any conflict between the provisions of your Award and those of the
Plan, the provisions of the Plan shall control.

                                       3.
