                                 URS CORPORATION
                           1999 EQUITY INCENTIVE PLAN

                       NONSTATUTORY STOCK OPTION AGREEMENT

      Pursuant to your Stock Option Grant Notice ("Grant Notice") and this Stock
Option Agreement, URS Corporation (the "Company") has granted you an option
under its 1999 Equity Incentive Plan (the "Plan") to purchase the number of
shares of the Company's Common Stock indicated in your Grant Notice at the
exercise price indicated in your Grant Notice. Defined terms not explicitly
defined in this Stock Option Agreement but defined in the Plan shall have the
same definitions as in the Plan.

      The details of your option are as follows:

      1. VESTING. Subject to the limitations contained herein, your option will
vest as provided in your Grant Notice, provided that vesting will cease upon the
termination of your Continuous Service.

      2. NUMBER OF SHARES AND EXERCISE PRICE. The number of shares of Common
Stock subject to your option and your exercise price per share referenced in
your Grant Notice may be adjusted from time to time for Capitalization
Adjustments, as provided in the Plan.

      3. METHOD OF PAYMENT. Payment of the exercise price is due in full upon
exercise of all or any part of your option as follows:

            (a) You may elect to make payment of the exercise price in any
manner PERMITTED BY YOUR GRANT NOTICE, which may include one or more of the
following:

                  (i) In cash or by check;

                  (ii) In the Company's sole discretion at the time your option
is exercised, and provided that at the time of exercise the Common Stock is
publicly traded and quoted regularly in The Wall Street Journal, pursuant to a
same day sale program developed under Regulation T as promulgated by the Federal
Reserve Board that, prior to the issuance of Common Stock, results in either the
receipt of cash (or check) by the Company or the receipt of irrevocable
instructions to pay the aggregate exercise price to the Company from the sales
proceeds; or

                  (iii) Provided that at the time of exercise the Common Stock
is publicly traded and quoted regularly in The Wall Street Journal, by delivery
of already-owned shares of Common Stock either that you have held for the period
required to avoid a charge to the Company's reported earnings (generally six
months) or that you did not acquire, directly or indirectly from the Company,
that are owned free and clear of any liens, claims, encumbrances or security
interests, and that are valued at Fair Market Value on the date of exercise.
"Delivery"

<PAGE>

for these purposes, in the sole discretion of the Company at the time you
exercise your option, shall include delivery to the Company of your attestation
of ownership of such shares of Common Stock in a form approved by the Company.
Notwithstanding the foregoing, you may not exercise your option by tender to the
Company of Common Stock to the extent such tender would violate the provisions
of any law, regulation or agreement restricting the redemption of the Company's
stock.

            (b) If and when expressly authorized by the Compensation Committee
of the Board of Directors and PERMITTED BY YOUR GRANT NOTICE, you may "net
exercise" your option in such manner as the Compensation Committee may
authorize, whereby the Company will deliver to you upon such exercise, subject
to withholding pursuant to Section 10 below, that number of shares equal to the
quotient of (i) the excess of the aggregate Fair Market Value of the number of
shares of Common Stock as to which your option is being exercised over the
aggregate exercise price of your option as to such number of shares, divided by
(ii) the Fair Market Value.

      4. MINIMUM EXERCISE. You may not exercise your option for less than one
hundred (100) shares of Common Stock at any one time, except that it may be
exercised for all of the Common Stock remaining subject to the option if fewer
than one hundred (100) shares remain. You may exercise your option only for
whole shares of Common Stock.

      5. SECURITIES LAW COMPLIANCE. Notwithstanding anything to the contrary
contained herein, you may not exercise your option unless the shares of Common
Stock issuable upon such exercise are then registered under the Securities Act
or, if such shares of Common Stock are not then so registered, the Company has
determined that such exercise and issuance would be exempt from the registration
requirements of the Securities Act. The exercise of your option must also comply
with other applicable laws and regulations governing your option, and you may
not exercise your option if the Company determines that such exercise would not
be in material compliance with such laws and regulations.

      6. TERM. You may not exercise your option before the commencement of its
term or after its term expires. The term of your option commences on the Date of
Grant and expires upon the EARLIEST of the following:

            (a) three (3) months after the termination of your Continuous
Service for any reason other than your retirement from the Company on or after
the date you attain age 65, Disability or death, provided that if during any
part of such three- (3-) month period you may not exercise your option solely
because of the condition set forth in the preceding paragraph relating to
"Securities Law Compliance," your option shall not expire until the earlier of
the Expiration Date or until it shall have been exercisable for an aggregate
period of three (3) months after the termination of your Continuous Service;

            (b) three (3) years after your retirement from the Company, if such
retirement occurs on or after the date you attain age 65;

            (c) twelve (12) months after the termination of your Continuous
Service due to your Disability;

<PAGE>

            (d) twelve (12) months after your death if you die either during
your Continuous Service or within three (3) months after your Continuous Service
terminates for any reason other than your retirement from the Company on or
after the date you attain age 65;

            (e) the Expiration Date indicated in your Grant Notice; or

            (f) the day before the tenth (10th) anniversary of the Date of
Grant.

      7. EXERCISE.

            (a) You may exercise the vested portion of your option during its
term by delivering a Notice of Exercise (in a form designated by the Company)
together with the exercise price to the Secretary of the Company, or to such
other person as the Company may designate, during regular business hours,
together with such additional documents as the Company may then require.

            (b) By exercising your option you agree that, as a condition to any
exercise of your option, the Company may require you to enter into an
arrangement providing for the payment by you to the Company of any tax
withholding obligation of the Company arising by reason of (1) the exercise of
your option or (2) the disposition of shares of Common Stock acquired upon such
exercise.

      8. TRANSFERABILITY. Your option is not transferable, except by will or by
the laws of descent and distribution, and is exercisable during your life only
by you. Notwithstanding the foregoing, by delivering written notice to the
Company, in a form satisfactory to the Company, you may designate a third party
who, in the event of your death, shall thereafter be entitled to exercise your
option.

      9. OPTION NOT A SERVICE CONTRACT. Your option is not an employment or
service contract, and nothing in your option shall be deemed to create in any
way whatsoever any obligation on your part to continue in the employ of the
Company or an Affiliate, or of the Company or an Affiliate to continue your
employment. In addition, nothing in your option shall obligate the Company or an
Affiliate, their respective shareholders, Boards of Directors, Officers or
Employees to continue any relationship that you might have as a Director or
Consultant for the Company or an Affiliate.

      10. WITHHOLDING OBLIGATIONS.

            (a) At the time you exercise your option, in whole or in part, 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 (including by means of a "cashless
exercise" pursuant to a program developed under Regulation T as promulgated by
the Federal Reserve Board to the extent permitted by the Company), any sums
required to satisfy the federal, state, local and foreign tax withholding
obligations of the Company or an Affiliate, if any, which arise in connection
with your option.

            (b) Upon your request and subject to approval by the Company, in its
sole discretion, and compliance with any applicable conditions or restrictions
of law, the Company

<PAGE>

may withhold from fully vested shares of Common Stock otherwise issuable to you
upon the exercise of your option a number of whole shares of Common Stock having
a Fair Market Value, determined by the Company as of the date of exercise, that
satisfies federal, state, local and foreign tax obligations of the Company and
you; provided that the Company shall not withhold shares of Common Stock at
rates in excess of the minimum statutory withholding rates imposed upon the
Company for federal and state tax purposes if such withholding would result in a
charge to the Company's earnings for accounting purposes. Any adverse
consequences to you arising in connection with such share withholding procedure
shall be your sole responsibility.

            (c) You may not exercise your option unless the tax withholding
obligations of the Company and/or any Affiliate are satisfied. Accordingly, you
may not be able to exercise your option when desired even though your option is
vested, and the Company shall have no obligation to issue a certificate for such
shares of Common Stock or release such shares of Common Stock from any escrow
provided for herein.

      11. NOTICES. Any notices provided for in your option or the Plan shall be
given in writing and shall be deemed effectively given upon receipt or, in the
case of notices delivered by mail 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.

      12. GOVERNING PLAN DOCUMENT. Your option is subject to all the provisions
of the Plan, the provisions of which are hereby made a part of your option, 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 option and those of the
Plan, the provisions of the Plan shall control.<PAGE>

parameters as the Board or the Committee may establish from time to time. The
delegation of authority shall be subject to such resolutions, not inconsistent
with the provisions of the Plan, as may be adopted from time to time by the
Board or the Committee. The Board or the Committee may abolish any such
delegation of authority at any time and revest in the Board or the Committee the
administration of the Plan.

4. SHARES SUBJECT TO THE PLAN.

      (a) SHARE RESERVE. Subject to the provisions of Section 12 relating to
adjustments upon changes in Common Stock, the Common Stock that may be issued
pursuant to Stock Awards shall not exceed in the aggregate one million five
hundred thousand (1,500,000) shares of Common Stock plus (i) the number of
shares of Common Stock added to the share reserve

<PAGE>

pursuant to the next sentence of this subsection 4(a), (ii) the number of shares
of Common Stock remaining available for award under the Company's 1991 Stock
Incentive Plan (the "1991 Plan") on the Effective Date of this Plan, (iii) the
number of shares of Common Stock that were issuable pursuant to options or stock
award agreements under the 1991 Plan that revert to the share reserve pursuant
to subsection 4(b) below and (iv) the number of shares of Common Stock remaining
available for award under the Company's Non-Executive Directors Stock Grant Plan
on the Effective Date of this Plan. As of each July 1, beginning with July 1,
2000 and continuing through and including July 1, 2009, the number of reserved
shares shall be increased automatically by the lesser of (i) five percent (5%)
of the total number of shares of Common Stock outstanding, including for this
purpose outstanding shares of capital stock convertible to Common Stock, on such
date or (ii) one million five hundred thousand (1,500,000) shares of Common
Stock.

      (b) REVERSION OF SHARES TO THE SHARE RESERVE.

            (i) EXPIRATION OR TERMINATION OF STOCK AWARD. If any Stock Award
granted under this Plan or any option or stock award agreement granted under the
1991 Plan shall for any reason expire or otherwise terminate, in whole or in
part, without having been exercised in full, the shares of Common Stock not
acquired under such Stock Award shall revert to and again become available for
issuance under the Plan.

            (ii) ISSUANCE OF COMMON STOCK. To the extent that any shares of
Common Stock are not issued to a Participant upon the exercise of an Option
granted under this Plan, such shares shall revert to and again become available
for issuance under this Plan. If shares of Common Stock are not issued to a
Participant because the Common Stock issuable upon the exercise of the Option is
used to satisfy an applicable tax withholding requirement, such shares will be
deemed not to have been issued to a Participant. In addition, if the exercise
price of any Option is satisfied by a Participant's tender of shares of Common
Stock to the Company (by actual delivery or attestation), only the number of
shares of Common Stock issued net of the shares so tendered shall be deemed
issued to the Participant.

      (c) SOURCE OF SHARES. The shares of Common Stock subject to the Plan may
be unissued shares or reacquired shares, bought on the market or otherwise.

5. ELIGIBILITY.

      (a) ELIGIBILITY FOR SPECIFIC STOCK AWARDS. Incentive Stock Options may be
granted only to Employees. Stock Awards other than Incentive Stock Options may
be granted to Employees, Directors and Consultants. Non-Executive Director Stock
Awards may be granted only to Non-Executive Directors and only pursuant to the
formula set forth in Section 8.

      (b) TEN PERCENT STOCKHOLDERS. A Ten Percent Stockholder shall not be
granted an Incentive Stock Option unless the exercise price of such Option is at
least one hundred ten percent (110%) of the Fair Market Value of the Common
Stock at the date of grant and the Option is not exercisable after the
expiration of five (5) years from the date of grant.

      (c) CONSULTANTS. A Consultant shall not be eligible for the grant of a
Stock Award if, at the time of grant, a Form S-8 Registration Statement under
the Securities Act ("Form S-8") is

<PAGE>

not available to register either the offer or the sale of the Company's
securities to such Consultant because of the nature of the services that the
Consultant is providing to the Company, or because the Consultant is not a
natural person, or as otherwise provided by the rules governing the use of Form
S-8, unless the Company determines both (i) that such grant (A) shall be
registered in another manner under the Securities Act (e.g., on a Form S-3
Registration Statement) or (B) does not require registration under the
Securities Act in order to comply with the requirements of the Securities Act,
if applicable, and (ii) that such grant complies with the securities laws of all
other relevant jurisdictions.

      (d) SECTION 162(m) LIMITATION. Subject to the provisions of Section 12
relating to adjustments upon changes in the shares of Common Stock, no Employee
shall be eligible to be granted Options covering more than one million
(1,000,000) shares of the Common Stock during any fiscal year of the Company.

6. OPTION PROVISIONS.

      Each Option shall be in such form and shall contain such terms and
conditions as the Board shall deem appropriate. All Options shall be separately
designated Incentive Stock Options or Nonstatutory Stock Options at the time of
grant, and, if certificates are issued, a separate certificate or certificates
will be issued for shares of Common Stock purchased on exercise of each type of
Option. The provisions of separate Options need not be identical, but each
Option shall include (through incorporation of provisions hereof by reference in
the Option or otherwise) the substance of each of the following provisions:

      (a) TERM. Subject to the provisions of subsection 5(b) regarding Ten
Percent Stockholders, no Incentive Stock Option shall be exercisable after the
expiration of ten (10) years from the date it was granted.

      (b) EXERCISE PRICE OF AN INCENTIVE STOCK OPTION. Subject to the provisions
of subsection 5(b) regarding Ten Percent Stockholders, the exercise price of
each Incentive Stock Option shall be not less than one hundred percent (100%) of
the Fair Market Value of the Common Stock subject to the Option on the date the
Option is granted. Notwithstanding the foregoing, an Incentive Stock Option may
be granted with an exercise price lower than that set forth in the preceding
sentence if such Option is granted pursuant to an assumption or substitution for
another option in a manner satisfying the provisions of Section 424(a) of the
Code.

      (c) EXERCISE PRICE OF A NONSTATUTORY STOCK OPTION. The exercise price of
each Nonstatutory Stock Option shall be not less than one hundred percent (100%)
of the Fair Market Value of the Common Stock subject to the Option on the date
the Option is granted. Notwithstanding the foregoing, a Nonstatutory Stock
Option may be granted with an exercise price lower than that set forth in the
preceding sentence if (i) such Option is granted with an exercise price of not
less than fifty percent (50%) of the Fair Market Value of the Common Stock
subject to the Option to an individual who is not employed by the Company or an
Affiliate immediately prior to the date of grant of the Option to induce such
individual to accept employment with the Company or an Affiliate or (ii) such
Option is granted pursuant to an

<PAGE>

assumption or substitution for another option in a manner satisfying the
provisions of Section 424(a) of the Code.

      (d) CONSIDERATION. The purchase price of Common Stock acquired pursuant to
an Option shall be paid, to the extent permitted by applicable statutes and
regulations, either (i) in cash at the time the Option is exercised or (ii) at
the discretion of the Board at the time of the grant of the Option (or
subsequently in the case of a Nonstatutory Stock Option): (1) by delivery to the
Company of other Common Stock that has been held by the Optionee for more than
six (6) months, which delivery may be made by attestation or actual delivery,
(2) by delivery, in a form prescribed by the Company, of an irrevocable
direction to a securities broker approved by the Company to sell Common Stock
and to deliver all or part of the sales proceeds to the Company in payment of
all or part of the purchase price and applicable withholding taxes, (3)
according to a deferred payment or other similar arrangement with the Optionee
or (4) in any other form of legal consideration that may be acceptable to the
Board; provided, however, that at any time that the Company is incorporated in
Delaware, payment of the Common Stock's "par value," as defined in the Delaware
General Corporation Law, shall not be made by deferred payment. If, pursuant to
clause (ii)(2) above, the Optionee delivers shares of Common Stock that the
Optionee has acquired pursuant to a restricted stock award made under this Plan
or a stock award agreement made under the 1991 Plan and that have not yet
vested, the restrictions applicable to the delivered shares shall be imposed
upon the Common Stock issued upon the exercise of the Option.

      In the case of any deferred payment arrangement, interest shall be
compounded at least annually and shall be charged at the minimum rate of
interest necessary to avoid the treatment as interest, under any applicable
provisions of the Code, of any amounts other than amounts stated to be interest
under the deferred payment arrangement.

      (e) TRANSFERABILITY OF AN INCENTIVE STOCK OPTION. An Incentive Stock
Option shall not be transferable except by will or by the laws of descent and
distribution and shall be exercisable during the lifetime of the Optionee only
by the Optionee. Notwithstanding the foregoing, the Optionee may, by delivering
written notice to the Company, in a form satisfactory to the Company, designate
a third party who, in the event of the death of the Optionee, shall thereafter
be entitled to exercise the Option.

      (f) TRANSFERABILITY OF A NONSTATUTORY STOCK OPTION. A Nonstatutory Stock
Option shall be transferable to the extent provided in the Option Agreement. If
the Nonstatutory Stock Option does not provide for transferability, then the
Nonstatutory Stock Option shall not be transferable except by will or by the
laws of descent and distribution and shall be exercisable during the lifetime of
the Optionee only by the Optionee. Notwithstanding the foregoing, the Optionee
may, by delivering written notice to the Company, in a form satisfactory to the
Company, designate a third party who, in the event of the death of the Optionee,
shall thereafter be entitled to exercise the Option.

      (g) VESTING GENERALLY. The total number of shares of Common Stock subject
to an Option may, but need not, vest and therefore become exercisable in
periodic installments that may, but need not, be equal. The Option may be
subject to such other terms and conditions on the time or times when it may be
exercised (which may be based on performance or other

<PAGE>

criteria) as the Board may deem appropriate. The vesting provisions of
individual Options may vary. The provisions of this subsection 6(g) are subject
to any Option provisions governing the minimum number of shares of Common Stock
as to which an Option may be exercised.

      (h) TERMINATION OF CONTINUOUS SERVICE. In the event an Optionee's
Continuous Service terminates (other than upon the Optionee's death or
Disability), the Optionee may exercise his or her Option (to the extent that the
Optionee was entitled to exercise such Option as of the date of termination) but
only within such period of time ending on the earlier of (i) the date three (3)
months following the termination of the Optionee's Continuous Service (or such
longer or shorter period specified in the Option Agreement) or (ii) the
expiration of the term of the Option as set forth in the Option Agreement. If,
after termination of Continuous Service, the Optionee does not exercise his or
her Option within the time specified in the Option Agreement, the Option shall
terminate.

      (i) EXTENSION OF TERMINATION DATE. An Optionee's Option Agreement may also
provide that if the exercise of the Option following the termination of the
Optionee's Continuous Service (other than upon the Optionee's death or
Disability) would be prohibited at any time solely because the issuance of
shares of Common Stock would violate the registration requirements under the
Securities Act, then the Option shall terminate on the earlier of (i) the
expiration of the term of the Option set forth in subsection 6(a) or (ii) the
expiration of a period of three (3) months after the termination of the
Optionee's Continuous Service during which the exercise of the Option would not
be in violation of such registration requirements.

      (j) DISABILITY OF OPTIONEE. In the event that an Optionee's Continuous
Service terminates as a result of the Optionee's Disability, the Optionee may
exercise his or her Option (to the extent that the Optionee was entitled to
exercise such Option as of the date of termination), but only within such period
of time ending on the earlier of (i) the date twelve (12) months following such
termination (or such longer or shorter period specified in the Option Agreement)
or (ii) the expiration of the term of the Option as set forth in the Option
Agreement. If, after termination of Continuous Service, the Optionee does not
exercise his or her Option within the time specified herein, the Option shall
terminate.

      (k) DEATH OF OPTIONEE. In the event (i) an Optionee's Continuous Service
terminates as a result of the Optionee's death or (ii) the Optionee dies within
the period (if any) specified in the Option Agreement after the termination of
the Optionee's Continuous Service for a reason other than death, then the Option
may be exercised (to the extent the Optionee was entitled to exercise such
Option as of the date of death) by the Optionee's estate, by a person who
acquired the right to exercise the Option by bequest or inheritance or by a
person designated to exercise the Option upon the Optionee's death pursuant to
subsection 6(e) or 6(f), but only within the period ending on the earlier of (1)
the date twelve (12) months following the date of death (or such longer or
shorter period specified in the Option Agreement) or (2) the expiration of the
term of such Option as set forth in the Option Agreement. If, after death, the
Option is not exercised within the time specified herein, the Option shall
terminate.

      (l) EARLY EXERCISE. The Option may, but need not, include a provision
whereby the Optionee may elect at any time before the Optionee's Continuous
Service terminates to exercise the Option as to any part or all of the shares of
Common Stock subject to the Option prior to the

<PAGE>

full vesting of the Option. Any unvested shares of Common Stock so purchased may
be subject to a repurchase option in favor of the Company or to any other
restriction the Board determines to be appropriate.

7. PROVISIONS OF RESTRICTED STOCK AWARDS.

      Each restricted stock purchase agreement shall be in such form and shall
contain such terms and conditions as the Board shall deem appropriate. The terms
and conditions of restricted stock purchase agreements may change from time to
time, and the terms and conditions of separate restricted stock purchase
agreements need not be identical, but each restricted stock purchase agreement
shall include (through incorporation of provisions hereof by reference in the
agreement or otherwise) the substance of each of the following provisions:

      (a) CONSIDERATION. A restricted stock award may be awarded in
consideration for past services actually rendered to the Company or an Affiliate
for its benefit.

      (b) VESTING. Shares of Common Stock acquired under a restricted stock
purchase agreement may, but need not, be subject to a share repurchase option in
favor of the Company in accordance with a vesting schedule to be determined by
the Board. The restricted stock award may be subject to such other terms and
conditions on the time or times at which it may be exercised (which may be based
on performance or other criteria) as the Board may deem appropriate. The vesting
provisions of individual restricted stock awards may vary.

      (c) TERMINATION OF PARTICIPANT'S CONTINUOUS SERVICE. In the event a
Participant's Continuous Service terminates, the Company may repurchase or
otherwise reacquire any or all of the shares of Common Stock held by the
Participant which have not vested as of the date of termination under the terms
of the restricted stock purchase agreement.

      (d) TRANSFERABILITY. Rights to acquire shares under the restricted stock
purchase agreement shall be transferable by the Participant only upon such terms
and conditions as are set forth in the restricted stock purchase agreement, as
the Board shall determine in its discretion, so long as Common Stock awarded
under the restricted stock purchase agreement remains subject to the terms of
the restricted stock purchase agreement. Notwithstanding the foregoing, the
Participant may, by delivering written notice to the Company, in a form
satisfactory to the Company, designate a third party who, in the event of the
death of the Participant, shall thereafter be entitled to receive shares of
Common Stock that have become vested as of the date of the Participant's death.

8. NON-EXECUTIVE DIRECTOR STOCK AWARDS.

      (a) Without any further action of the Board or any committee thereof, each
Non-Executive Director shall be granted a Non-Executive Director Stock Award at
each of the times specified in subsection 8(a)(1) below, which Non-Executive
Director Award shall have the terms set forth in subsections 8(a)(2) and 8(a)(3)
below. Such award shall result in the issuance and delivery of shares of the
Corporation's Common Stock to the Non-Executive Director on the date of grant.

<PAGE>

            (i) QUARTERLY GRANTS. Each Non-Executive Director who is serving as
a Non-Executive Director on the last day of each of the Corporation's fiscal
quarters shall be granted a Non-Executive Director Stock Award on such day (a
"Quarterly Grant").

            (ii) NUMBER OF SHARES. The number of shares of the Corporation's
Common Stock subject to each Quarterly Grant will be equal to the quotient of
Eight Thousand Seven Hundred Fifty Dollars ($8,750) divided by the Fair Market
Value of the Common Stock on the date of grant, rounded down to the nearest
whole share.

            (iii) VESTING. Each Quarterly Grant shall be fully vested on the
date of grant.

      (b) DEFERRED STOCK AWARDS. Without any further action of the Board or any
committee thereof, each Non-Executive Director shall be granted a deferred
Non-Executive Director Stock Award at the time specified in subsection 8(b)(1)
below, which deferred Non-Executive Director Stock Award shall have the terms
set forth in subsections 8(b)(2) and 8(b)(3) below. Until shares of the
Corporation's Common Stock are issued pursuant to subsection 8(b)(3) below in
respect of a deferred Non-Executive Director Stock Award, such Award shall
represent a notional number of shares and a promise by the Corporation to issue
to the Non-Executive Director such number of shares (subject to adjustment as
provided in Section 12(a)), and the Non-Executive Director shall have no
stockholder or other ownership rights (including, but not limited to, the right
to receive any dividend paid) in respect of such shares until their issuance.

            (i) QUARTERLY GRANTS. Each Non-Executive Director who is serving as
a Non-Executive Director on the last day of each of the Corporation's fiscal
quarters shall be granted a deferred Non-Executive Director Stock Award on such
day (a "Quarterly Deferred Grant").

            (ii) NUMBER OF SHARES. Each Quarterly Deferred Grant will entitle
the Non-Executive Director to receive, at the time specified in subsection
8(b)(3) below, a number of shares of the Corporation's Common Stock equal to the
quotient of Eight Thousand Seven Hundred Fifty Dollars ($8,750) divided by the
Fair Market Value of the Common Stock on the date of grant, rounded down to the
nearest whole share (and subject to adjustment as necessary).

            (iii) VESTING; ISSUANCE. Each Quarterly Deferred Grant shall be
fully vested on the date of grant; provided that the notional number of shares
of the Corporation's Common Stock in respect of each Quarterly Deferred Grant
shall not be issued or issuable, and instead shall accumulate and be credited by
the Corporation to a bookkeeping account in the name of such Director, until
such time as the Director terminates his or her service on the Board of
Directors for any reason, at which time the Corporation shall issue and deliver
to the Non-Executive Director, within thirty (30) days of such termination of
service, a number of shares of the Corporation's Common Stok equal to the
cumulative notional number of shares (as adjusted) in respect of such Director's
cumulative Quarterly Deferred Grants.

      (c) CONSIDERATION. Each Quarterly Grant and Quarterly Deferred Grant shall
be awarded in consideration for services rendered as a Non-Executive Director.

<PAGE>

      (d) AMENDMENT OF TERMS OF NON-EXECUTIVE DIRECTOR STOCK AWARDS. The Board
may at any time, and from time to time, amend the terms pursuant to which
Non-Executive Director Stock Awards, including the Quarterly Grants and
Quarterly Deferred Grants, shall be granted including, without limitation,
amendment of the dollar amount specified in subsections 8(a)(2) and 8(b)(2)
above and any other provision of this Section 8.

9. COVENANTS OF THE COMPANY.

      (a) AVAILABILITY OF SHARES. During the terms of the Stock Awards, the
Company shall keep available at all times the number of shares of Common Stock
required to satisfy such Stock Awards.

      (b) LEGAL COMPLIANCE. The Company shall seek to obtain from each
regulatory commission or agency having jurisdiction over the Plan such authority
as may be required to grant Stock Awards and to issue and sell shares of Common
Stock upon exercise of the Stock Awards; provided, however, that this
undertaking shall not require the Company to register under the Securities Act
the Plan, any Stock Award or any Common Stock issued or issuable pursuant to any
such Stock Award. If, after reasonable efforts, the Company is unable to obtain
from any such regulatory commission or agency the authority which counsel for
the Company deems necessary for the lawful issuance and sale of Common Stock
under the Plan, the Company shall be relieved from any liability for failure to
issue and sell Common Stock upon exercise of such Stock Awards unless and until
such authority is obtained.

10. USE OF PROCEEDS FROM STOCK.

            Proceeds from the sale of Common Stock pursuant to Stock Awards
shall constitute general funds of the Company.

11. MISCELLANEOUS.

      (a) ACCELERATION OF EXERCISABILITY AND VESTING. The Board shall have the
power to accelerate the time at which a Stock Award may first be exercised or
the time during which a Stock Award or any part thereof will vest in accordance
with the Plan, notwithstanding the provisions in the Stock Award stating the
time at which it may first be exercised or the time during which it will vest.

      (b) STOCKHOLDER RIGHTS. No Participant shall be deemed to be the holder
of, or to have any of the rights of a holder with respect to, any shares of
Common Stock subject to such Stock Award unless and until such Participant has
satisfied all requirements for exercise of the Stock Award pursuant to its
terms.

      (c) NO EMPLOYMENT OR OTHER SERVICE RIGHTS. Nothing in the Plan or any
instrument executed or Stock Award granted pursuant thereto shall confer upon
any Participant any right to continue to serve the Company or an Affiliate in
the capacity in effect at the time the Stock Award was granted or shall affect
the right of the Company or an Affiliate to terminate (i) the employment of an
Employee with or without notice and with or without cause, (ii) the service of a
Consultant pursuant to the terms of such Consultant's agreement with the Company
or an Affiliate or (iii) the service of a Director pursuant to the Bylaws of the
Company or an Affiliate,

<PAGE>

and any applicable provisions of the corporate law of the state in which the
Company or the Affiliate is incorporated, as the case may be.

      (d) INCENTIVE STOCK OPTION $100,000 LIMITATION. To the extent that the
aggregate Fair Market Value (determined at the time of grant) of Common Stock
with respect to which Incentive Stock Options are exercisable for the first time
by any Optionee during any calendar year (under all plans of the Company and its
Affiliates) exceeds one hundred thousand dollars ($100,000), the Options or
portions thereof which exceed such limit (according to the order in which they
were granted) shall be treated as Nonstatutory Stock Options.

      (e) INVESTMENT ASSURANCES. The Company may require a Participant, as a
condition of exercising or acquiring Common Stock under any Stock Award, (i) to
give written assurances satisfactory to the Company as to the Participant's
knowledge and experience in financial and business matters and/or to employ a
purchaser representative reasonably satisfactory to the Company who is
knowledgeable and experienced in financial and business matters and that he or
she is capable of evaluating, alone or together with the purchaser
representative, the merits and risks of exercising the Stock Award and (ii) to
give written assurances satisfactory to the Company stating that the Participant
is acquiring Common Stock subject to the Stock Award for the Participant's own
account and not with any present intention of selling or otherwise distributing
the Common Stock. The foregoing requirements, and any assurances given pursuant
to such requirements, shall be inoperative if (A) the issuance of the shares of
Common Stock upon the exercise or acquisition of Common Stock under the Stock
Award has been registered under a then currently effective registration
statement under the Securities Act or (B) as to any particular requirement, a
determination is made by counsel for the Company that such requirement need not
be met in the circumstances under the then applicable securities laws. The
Company may, upon advice of counsel to the Company, place legends on stock
certificates issued under the Plan as such counsel deems necessary or
appropriate in order to comply with applicable securities laws, including, but
not limited to, legends restricting the transfer of the Common Stock.

      (f) WITHHOLDING OBLIGATIONS. To the extent provided by the terms of a
Stock Award Agreement, the Participant may satisfy any federal, state, local or
foreign tax withholding obligation relating to the exercise or acquisition of
Common Stock under a Stock Award by any of the following means (in addition to
the Company's right to withhold from any compensation paid to the Participant by
the Company) or by a combination of such means: (i) tendering a cash payment,
(ii) authorizing the Company to withhold shares of Common Stock from the shares
of Common Stock otherwise issuable to the Participant as a result of the
exercise or acquisition of Common Stock under the Stock Award or (iii)
delivering to the Company owned and unencumbered shares of the Common Stock.
Notwithstanding the foregoing, the Company shall not be authorized to withhold
shares of Common Stock at rates in excess of the minimum statutory withholding
rates imposed upon the Company for federal and state tax purposes if such
withholding would result in a charge to the Company's earnings for accounting
purposes.

12. ADJUSTMENTS UPON CHANGES IN STOCK.

      (a) CAPITALIZATION ADJUSTMENTS. If any change is made in the Common Stock
subject to the Plan, or subject to any Stock Award, without the receipt of
consideration by the

<PAGE>

Company (through merger, consolidation, reorganization, recapitalization,
reincorporation, stock dividend, dividend in property other than cash, stock
split, liquidating dividend, combination of shares, exchange of shares, change
in corporate structure or other transaction not involving the receipt of
consideration by the Company), the Plan will be appropriately adjusted in the
class(es) and maximum number of securities subject to the Plan pursuant to
subsection 4(a) and the maximum number of securities subject to award to any
person pursuant to subsection 5(d), and the outstanding Stock Awards will be
appropriately adjusted in the class(es) and number of securities and price per
share of Common Stock subject to such outstanding Stock Awards. The Board shall
make such adjustments, and its determination shall be final, binding and
conclusive. (The conversion of any convertible securities of the Company shall
not be treated as a transaction "without receipt of consideration" by the
Company.)

      (b) DISSOLUTION OR LIQUIDATION. In the event of a dissolution or
liquidation of the Company, then all outstanding Stock Awards shall terminate
immediately prior to such event.

      (c) CHANGE IN CONTROL. Unless otherwise provided in the Stock Award
Agreement, in the event of a Change in Control, then (i) prior to the completion
of the Change in Control, any surviving entity or controlling entity may assume
any Stock Awards outstanding under the Plan or may substitute similar stock
awards (including an award to acquire the same consideration paid to the
stockholders in the Change in Control) for those outstanding under the Plan or
(ii) prior to the completion of the Change in Control, the Board may, in its
sole discretion, make cash payments to Participants holding Stock Awards in
amounts that the Board determines represent the cash value of the outstanding
Stock Awards and such payments shall completely discharge the Company's
obligations under such outstanding Stock Awards. In the event (i) any surviving
corporation or acquiring corporation does not assume such Stock Awards or
substitute similar stock awards for those outstanding under the Plan and (ii)
the Board does not settle the outstanding Stock Awards in cash, then (a) with
respect to Stock Awards held by Participants whose Continuous Service has not
terminated, the vesting of such Stock Awards (and, if applicable, the time
during which such Stock Awards may be exercised) shall be accelerated in full as
of a time designated by the Board, and the Stock Awards shall terminate if not
exercised (if applicable) at or prior to a time designated by the Board and (b)
with respect to any other Stock Awards outstanding under the Plan, such Stock
Awards shall terminate if not exercised (if applicable) prior to a time
designated by the Board.

13. LIMITATION ON PAYMENTS.

      (a) BASIC RULE. Any provision of the Plan to the contrary notwithstanding,
in the event that the independent auditors most recently selected by the Board
(the "Auditors") determine that any payment or transfer by the Company to or for
the benefit of a Participant, whether paid or payable (or transferred or
transferable) pursuant to the terms of this Plan or otherwise (a "Payment"),
would be nondeductible by the Company for federal income tax purposes because of
the provisions concerning "excess parachute payments" in Section 280G of the
Code, then the aggregate present value of all Payments shall be reduced (but not
below zero) to the Reduced Amount; provided that the Board, at the time of
granting a Stock Award under this Plan or at any time thereafter, may specify in
writing that such Award shall not be so reduced and shall not be subject to this
Section 13. For purposes of this Section 13, the "Reduced Amount" shall be the
amount, expressed as a present value, which maximizes the aggregate

<PAGE>

present value of the Payments without causing any Payment to be nondeductible by
the Company because of section 280G of the Code.

      (b) REDUCTION OF PAYMENTS. If the Auditors determine that any Payment
would be nondeductible by the Company because of Section 280G of the Code, then
the Company shall promptly give the Participant notice to that effect and a copy
of the detailed calculation thereof and of the Reduced Amount, and the
Participant may then elect, in his or her sole discretion, which and how much of
the Payments shall be eliminated or reduced (as long as after such election the
aggregate present value of the Payments equals the Reduced Amount) and shall
advise the Company in writing of his or her election within ten (10) days of
receipt of notice; provided, however, that such election shall be subject to
Company approval if made on or after the effective date of a Change in Control.
If no such election is made by the Participant within such ten (10) day period,
then the Company may elect which and how much of the Payments shall be
eliminated or reduced (as long as after such election the aggregate present
value of the Payments equals the Reduced Amount) and shall notify the
Participant promptly of such election. For purposes of this Section 13, present
value shall be determined in accordance with Section 280G(d)(4) of the Code. All
determinations made by the Auditors under this Section 13 shall be binding upon
the Company and the Participant and shall be made within sixty (60) days of the
date when a payment becomes payable or transferable. As promptly as practicable
following such determination and the elections hereunder, the Company shall pay
or transfer to or for the benefit of the Participant such amounts as are then
due to him or her under the Plan and shall promptly pay or transfer to or for
the benefit of the Participant in the future such amounts as become due to him
or her under the Plan.

      (c) OVERPAYMENTS AND UNDERPAYMENTS. As a result of uncertainty in the
application of Section 280G of the Code at the time of an initial determination
by the Auditors hereunder, it is possible that Payments will have been made by
the Company which should not have been made (an "Overpayment") or that
additional Payments which will not have been made by the Company could have been
made (an "Underpayment"), consistent in each case with the calculation of the
Reduced Amount hereunder. In the event that the Auditors determine, based upon
the assertion of a deficiency by the Internal Revenue Service against the
Company or the Participant which the Auditors believe has a high probability of
success, that an Overpayment has been made, such Overpayment shall be treated
for all purposes as a loan to the Participant which he or she shall repay to the
Company, together with interest at the applicable federal rate provided in
Section 7872(f)(2) of the Code; provided, however, that no amount shall be
payable by the Participant to the Company if and to the extent that such payment
would not reduce the amount that is subject to taxation under Section 4999 of
the Code. In the event that the Auditors determine that an Underpayment has
occurred, such Underpayment shall promptly be paid or transferred by the Company
to or for the benefit of the Participant, together with interest at the
applicable federal rate provided in Section 7872(f)(2) of the Code.

      (d) RELATED CORPORATIONS. For purposes of this Section 13, the term
"Company" shall include affiliated corporations to the extent determined by the
Auditors in accordance with Section 280G(d)(5) of the Code.
