the Company) confidential  information or proprietary data of the Company or URS

which  include  vacation  time accrual  limits.  In addition,  the Company shall
reimburse you for health insurance  premiums  required to be paid by you for one
(1) year to obtain  COBRA  continuation  coverage  within the meaning of Section
4980B(f)(2)  of the  Internal  Revenue Code of 1986,  as amended  (the  "Code"),
provided you elect such continuation  coverage;  provided,  however,  that in no
event  shall the  Company be  required  to make or provide  any such  payment or
benefit  unless  and until you have  executed  and  delivered  to the  Company a
release  in the form of  Exhibit  A to this

Agreement.

         4.2 Termination for Cause.

                  (a) The  Company  shall  have  the  right  to  terminate  your
employment with the Company at any time for Cause (as defined below).

                  (b) "Cause" for termination  shall mean: (i) your  substantial
failure or omission to perform your duties hereunder,  other than as a result of
your death or Disability (as defined  below);  (ii) your act involving  material
injury to the  Company  or to URS  Corporation  (or any  parent,  subsidiary  or
affiliated  corporation or related  entity of either of them),  willful or gross
misconduct,  fraud or dishonesty;  (iii) your conviction of, or plea of "guilty"
or "no contest" to, a felony; or (iv) your disobedience of orders and directives
of the Chief Executive Officer of URS Corporation or his designee.

arrangement  maintained  by the Company or a parent,  subsidiary  or  affiliated
corporation or related entity of the Company;  or (ii) you are unable to perform
the normal duties  assigned to you under this Agreement for a continuous  period
of 60 calendar days or any incapacity,  however caused,  that, in the good faith
opinion of the Chief Executive  Officer of URS  Corporation or his designee,  is
likely to prevent you from  performing  the normal duties  assigned to you under
this  Agreement for more than 90 calendar days in any twelve  consecutive  month
period  (taking into  account,  in the case of such an  inability or  incapacity
which is a physical or mental impairment that  substantially  limits one or more

by you or  the  Company,  the  Company  will  pay  you in a lump  sum an  amount
equivalent  to your base  salary  for one (1) year from the date of  termination
plus any accrued but unused  vacation  time computed at the base salary rate and
in accordance with Company  policies which include vacation time accrual limits.
In addition,  the Company  shall  reimburse  you for health  insurance  premiums
required  to be  paid by you for one  (1)  year  to  obtain  COBRA  continuation
coverage  within the meaning of the Code,  provided you elect such  continuation
coverage;  provided,  however, that in no event shall the Company be required to
make or provide any such payment or benefit  unless and until you have  executed
and  delivered  to the  Company  a  release  in the  form of  Exhibit  A to this
Agreement and seven (7) days have elapsed  following such execution and delivery

employment,  Employee agrees (i) to assist, as reasonably  requested by Company,
in the  transition  of Employee's  responsibilities  and (ii) not to solicit any

(ii) Employee  agrees to keep  confidential  all  information  contained in this
Release (except to the extent (A) Company consents in writing to disclosure, (B)
Employee  is  required by process of law to make such  disclosure  and  Employee
promptly  notifies  Company of receipt by Employee of such process,  or (C) such
information previously shall have become publicly available other than by breach

         Employee  acknowledges and agrees that neither anything in this Release
nor the offer, execution,  delivery, or acceptance thereof shall be construed as

evidence in any proceeding except to enforce this Release.

         It is the intention of Employee in executing  this  instrument  that it
shall be effective as a bar to each and every claim, demand, grievance and cause
of action  hereinabove  specified.  In furtherance of this  intention,  Employee
hereby expressly consents that this Release shall be given full force and effect

Employee  acknowledges  Employee may hereafter discover facts different from, or
in addition to, those  Employee now knows or believes to be true with respect to
the claims, demands, liens, agreements,  contracts,  covenants,  actions, suits,
causes of action,  wages,  obligations,  debts,  expenses,  damages,  judgments,
orders and liabilities  herein released,  and agrees the release herein shall be
and remain in effect in all respects as a complete and general release as to all
matters released herein, notwithstanding any such different or additional facts.

         If any  provision  of  this  Release  or  application  thereof  is held
invalid, the invalidity shall not affect other provisions or applications of the
Release which can be given effect without the invalid  provision or application.
To this end, the provisions of this Release are severable.

         Employee  represents  and warrants  that  Employee  has not  heretofore
assigned or transferred  or purported to assign or transfer to any person,  firm
or corporation any claim,  demand,  right,  damage,  liability,  debt,  account,
action, cause of action, or any other matter herein released.

                               NOTICE TO EMPLOYEE

Employee in writing to consult with an attorney and discuss this Release  before
executing it. Employee acknowledges Company has provided to Employee at least 21
calendar  days within which to review and consider this Release  before  signing
it.

         Should  Employee  decide  not to use the  full 21 days,  then  Employee
knowingly and voluntarily  waives any claims that Employee was not in fact given
that  period of time or did not use the entire 21 days to  consult  an  attorney
and/or  consider this Release.  Employee  acknowledges  that Employee may revoke
this Release for up to seven  calendar days  following  Employee's  execution

midnight on the seventh day following execution of this Release by Employee.  If
Employee  so  revokes  this  Release,  the  Release  shall not be  effective  or
enforceable  and  Employee  will not receive the monies and  benefits  described
above.  If  Employee  does not revoke this  Release in the time frame  specified
above,  the Release  shall become  effective at 12:00:01  A.M. on the eighth day
after it is signed by Employee.


                PLEASE READ CAREFULLY. THIS AGREEMENT CONTAINS A
                GENERAL RELEASE OF ALL KNOWN AND UNKNOWN CLAIMS.

         I have read and understood  the foregoing  General  Release,  have been
advised to and have had the  opportunity  to  discuss  it with  anyone I desire,
including  an attorney  of my own  choice,  and I accept and agree to its terms,
acknowledge  receipt of a copy of the same and the sufficiency of the monies and
benefits  described above, and hereby execute this Release  voluntarily and with
full understanding of its consequences.
